PROSPECTUS (Subject to Completion)
Issued February 8, 2012

25,000,000 Common Units

SandRidge Mississippian Trust II

Representing Beneficial Interests



This is an initial public offering of common units representing beneficial interests in SandRidge Mississippian Trust II. The trust is selling all of the units offered hereby. SandRidge Energy, Inc. ("SandRidge") will convey to the trust certain royalty interests in exchange for the net proceeds of this offering and common and subordinated units collectively representing a 48.2% beneficial interest in the trust (without giving effect to the exercise of the underwriters' over-allotment option). SandRidge anticipates that the initial public offering price will be between $                      and $                      per common unit.



The trust intends to apply to have the common units approved for listing on the New York Stock Exchange under the symbol "SDR."



The Trust Units.    Trust units, consisting of common and subordinated units, are units representing beneficial interests in the trust and represent undivided beneficial interests in the property of the trust. They do not represent any interest in SandRidge.

The Trust.    The trust will own overriding royalty interests in certain of SandRidge's properties in the Mississippian formation in northern Oklahoma and southern Kansas. These royalty interests will entitle the trust to receive, after the deduction of certain costs, (a) 80% of the proceeds attributable to SandRidge's net revenue interest in the sale of production from 67 producing wells and (b) 70% of the proceeds attributable to SandRidge's net revenue interest in the sale of production from 206 development wells to be drilled within an area of mutual interest consisting of approximately 81,200 gross acres (53,000 net acres) held by SandRidge. The trust will not be responsible for any costs related to the operation of the producing wells or the drilling or operation of the development wells. The trust will be treated as a partnership for U.S. federal income tax purposes.

The Trust Unitholders.    As a trust unitholder, you will receive quarterly distributions of cash from the proceeds that the trust receives from SandRidge's sale of oil and natural gas subject to the royalty interests to be held by the trust. The distributions will also reflect hedges entered into pursuant to a derivatives agreement between the trust and SandRidge, as well as hedges entered into by the trust directly with unaffiliated hedge counterparties. For information on target distributions and related matters pertinent to trust unitholders, please see "Target Distributions and Subordination and Incentive Thresholds."



Investing in the common units involves risks. See "Risk Factors" beginning on page 20.

These risks include the following:

Drilling for and producing oil and natural gas involves many risks that could delay the anticipated drilling schedule for the development wells to be drilled by SandRidge, which could adversely affect future production and decrease cash distributions to unitholders.

Oil and natural gas price fluctuations could reduce proceeds to the trust and cash distributions to unitholders.

Actual reserves and future production may be less than current estimates.

Estimates of target distributions to unitholders are based on assumptions that are inherently subjective and are subject to significant risks and uncertainties.

The hedging arrangements will cover only a portion of the expected production attributable to the trust, and such arrangements will limit the trust's ability to benefit from commodity price increases for hedged volumes above the corresponding hedge price.

If the trust were treated as a corporation for U.S. federal income tax purposes, then its cash available for distribution to unitholders would be substantially reduced.

If the IRS contests the tax positions the trust takes, the value of the trust units may be adversely affected, the cost of any IRS contest will reduce the trust's cash available for distribution and income, gain, loss and deduction may be reallocated among trust unitholders.

The tax treatment of an investment in trust units could be affected by potential legislative changes, possibly on a retroactive basis.

SUMMARY

        This summary provides a brief overview of information contained elsewhere in this prospectus. To understand this offering fully, you should read the entire prospectus carefully, including the risk factors and the financial statements and notes to those statements. Definitions for terms relating to the oil and natural gas business can be found in "Glossary of Certain Oil and Natural Gas Terms and Terms Related to the Trust." Netherland, Sewell & Associates, Inc., referred to in this prospectus as "Netherland Sewell," an independent engineering firm, provided the estimates of proved and probable oil and natural gas reserves as of December 31, 2011 included in this prospectus. These estimates are contained in summaries prepared by Netherland Sewell of its reserve reports for (1) the oil and natural gas properties held by SandRidge from which the royalty interests will be conveyed to the trust (the "Underlying Properties"), dated January 2, 2012, and (2) the royalty interests to be held by the trust, dated January 3, 2012. These summaries are included as Annex A to this prospectus and are referred to in this prospectus as the "reserve report."

        References to "SandRidge" in this prospectus are to SandRidge Energy, Inc. and, where the context requires, one or more of its subsidiaries. The royalty interests to be conveyed to the trust are sometimes referred to as the "trust properties."

        Unless otherwise indicated, all information in this prospectus assumes an initial public offering price of $        per common unit and no exercise of the underwriters' over-allotment option.

SandRidge Mississippian Trust II

        SandRidge Mississippian Trust II is a Delaware statutory trust formed in December 2011 to own (a) overriding royalty interests to be conveyed to the trust by SandRidge in 67 producing horizontal wells, including 13 wells currently awaiting completion (the "Producing Wells"), in the Mississippian formation in northern Oklahoma and southern Kansas, and (b) overriding royalty interests in 206 horizontal development wells (calculated as described under "—The Development Wells") to be drilled in the Mississippian formation (the "Development Wells") on properties within an Area of Mutual Interest (the "AMI"). The AMI, which is limited to the Mississippian formation and consists of approximately 81,200 gross acres (53,000 net acres) held by SandRidge, is depicted by the area identified on the inside front cover of this prospectus. The Mississippian formation is encountered at depths between approximately 4,000 feet and 7,000 feet and lies stratigraphically between the Pennsylvanian-aged Morrow formation and the Devonian-aged Woodford Shale formation. SandRidge intends to drill, or cause to be drilled, the Development Wells in the AMI by December 31, 2015 and is obligated to complete such drilling by December 31, 2016. Until SandRidge has satisfied its drilling obligation to the trust, it will not be permitted to drill and complete any wells for its own account within the AMI. See "The Trust—Development Agreement and Drilling Support Lien—Additional Provisions."

        The royalty interests will be conveyed from SandRidge's interest in the Producing Wells and the Development Wells effective as of January 1, 2012. The royalty interest in the Producing Wells (the "PDP Royalty Interest") entitles the trust to receive 80% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of oil and natural gas attributable to SandRidge's net revenue interest in the Producing Wells. The royalty interest in the Development Wells (the "Development Royalty Interest") entitles the trust to receive 70% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Development Wells.

        As of December 31, 2011, the total proved reserves estimated to be attributable to the trust were 26.1 million barrels of oil equivalent ("MMBoe"). This amount includes 10.2 MMBoe attributable to the PDP Royalty Interest and 15.9 MMBoe attributable to the Development Royalty Interest. The proved reserves consist of 46.8% oil and 53.2% natural gas. In addition, as of December 31, 2011, there were 9.8 MMBoe of probable reserves estimated to be attributable to the trust, all of which were attributable to

Table of Contents

the Development Royalty Interest. The probable reserves consist of 46.9% oil and 53.1% natural gas. Please see "The Underlying Properties—Oil and Natural Gas Reserves" and "The Underlying Properties—The Reserve Report" for information about the estimated reserves attributable to the trust.

        The percentage of production proceeds to be received by the trust with respect to a well will equal the product of (a) the percentage of proceeds to which the trust is entitled under the terms of the conveyances (80% for the Producing Wells and 70% for the Development Wells) multiplied by (b) SandRidge's net revenue interest in the well. SandRidge on average owns a 53.6% net revenue interest in the Producing Wells. Therefore, the trust will have an average 42.9% net revenue interest in the Producing Wells. SandRidge on average owns a 47.4% net revenue interest in the properties in the AMI on which it expects to drill the Development Wells, and based on this net revenue interest, the trust would have an average 33.2% net revenue interest in the Development Wells. SandRidge's actual net revenue interest in any particular Producing Well or Development Well may differ from these averages.

        The trust will not be responsible for any costs related to the drilling of the Development Wells or any other operating and capital costs, except for certain taxes and other post-production costs. The trust's cash receipts in respect of the trust properties will be determined after deducting post-production costs and any applicable taxes associated with the PDP Royalty Interest and the Development Royalty Interest. Post-production costs and applicable taxes will generally consist of production and severance taxes and costs incurred to gather, store, compress, transport, process, treat, dehydrate and market the oil and natural gas produced. However, the trust will not be responsible for costs of marketing services provided by SandRidge. Cash distributions to unitholders will reflect hedging arrangements, as well as trust general and administrative expenses.

        Hedging arrangements covering a portion of expected production will be implemented in two ways. First, SandRidge will enter into a derivatives agreement with the trust to provide the trust with the economic effect of specified hedge contracts entered into between SandRidge and unaffiliated counterparties. Under the derivatives agreement, SandRidge will pay the trust amounts it receives from its hedge counterparties, and the trust will pay SandRidge any amounts that SandRidge is required to pay such counterparties. Second, the trust will enter into hedge contracts directly with unaffiliated hedge counterparties. As a party to these contracts, the trust will receive payments directly from its counterparties, and be required to pay any amounts owed directly to its counterparties. Under the combined hedging arrangements, approximately    % of the expected production and    % of the expected revenues upon which the target distributions are based from        through        will be hedged. Under the derivatives agreement, as Development Wells are drilled, SandRidge will have the right to novate to the trust any of the SandRidge-provided hedges in certain circumstances. Please see "The Trust—Hedging Arrangements" and "Target Distributions and Subordination and Incentive Thresholds."

        The trust will make quarterly cash distributions of substantially all of its cash receipts, after deducting the trust's administrative expenses, on or about 60 days following the completion of each quarter through (and including) the quarter ending December 31, 2031. The first distribution, which will cover the first quarter of 2012 (consisting of proceeds attributable to two months of production due to the timing of payment of production proceeds to the trust), is expected to be made on or about May 30, 2012 to record unitholders as of May 15, 2012. The trustee intends to withhold $1.0 million from the first distribution to establish a cash reserve available for trust administrative expenses.

        The PDP Royalty Interest and the Development Royalty Interest will each consist of two separate royalty interests conveyed by SandRidge to the trust: (a) a term overriding royalty interest for a period of 20 years commencing on January 1, 2012 and ending on December 31, 2031 (the "Term Royalties") and (b) an overriding royalty interest in all oil and natural gas that may be produced from the subject properties (the "Perpetual Royalties"). The trust will dissolve and begin to liquidate on December 31, 2031 (such date is referred to as the "Termination Date") and will soon thereafter wind up its affairs and terminate. At the Termination Date, the Term Royalties will revert automatically to SandRidge. Following

Table of Contents

the Termination Date, the Perpetual Royalties will be sold by the trust, and the net proceeds of the sale, as well as any remaining trust cash reserves, will be distributed to the unitholders pro rata. SandRidge will have a right of first refusal to purchase the Perpetual Royalties from the trust following the Termination Date.

        SandRidge will retain 20% of the proceeds from the sale of oil and natural gas attributable to its net revenue interest in the Producing Wells, as well as 30% of the proceeds from the sale of future production attributable to its net revenue interest in the Development Wells. SandRidge initially will own 48.2% of the trust units (without giving effect to the exercise of the underwriters' over-allotment option). By virtue of SandRidge's retained interest in the Producing Wells and the Development Wells, as well as its ownership of 48.2% of the trust units, it will have an effective average net revenue interest of 31.4% in the Producing Wells and 30.2% in the Development Wells, compared with an effective average net revenue interest for the holders of trust units other than SandRidge of 22.2% in the Producing Wells and 17.2% in the Development Wells.

        SandRidge operates 79% of the Producing Wells and expects to operate approximately 67% of the Development Wells during the subordination period described herein. In addition, for those wells it operates, SandRidge has agreed to operate the properties and cause to be marketed oil and natural gas produced from these properties in the same manner it would if such properties were not burdened by the royalty interests.

        The business and affairs of the trust will be managed by The Bank of New York Mellon Trust Company, N.A., as trustee. However, the trustee will have no ability to manage or influence the operation of the Underlying Properties. SandRidge expects to operate substantially all of the Underlying Properties, but will have no ability to manage or influence the management of the trust except through its limited voting rights as a holder of trust units and its limited ability to manage the hedging program. Please see "The Trust—Hedging Arrangements," "The Trust—Administrative Services Agreement" and "Description of the Trust Units—Voting Rights of Trust Unitholders."

        The principal offices of the trust are located at 919 Congress Avenue, Suite 500, Austin, Texas 78701, and its telephone number is (512) 236-6599.

The Development Wells

        Pursuant to a development agreement with the trust, SandRidge intends to drill, or cause to be drilled, 206 Development Wells in the AMI by December 31, 2015 and is obligated to complete such drilling by December 31, 2016. SandRidge will be credited for drilling one full Development Well if the perforated length of the well bore (or the length of the well bore that is otherwise made ready to commence stimulation, which is also referred to in this prospectus as the "perforated length") is between 3,500 feet and 4,500 feet and SandRidge's net revenue interest in the well is equal to 47.4%. For wells with a perforated length of less than 3,500 feet, SandRidge will receive credit in the proportion that the well's perforated length bears to 3,500 feet, and for wells with a perforated length of more than 4,500 feet, SandRidge will receive credit in the proportion that the well's perforated length bears to 4,500 feet. For wells in which SandRidge has a net revenue interest greater than or less than 47.4%, SandRidge will receive credit for such well in the proportion that its net revenue interest in the well bears to 47.4%. As a result, SandRidge may be required to drill more or less than 206 wells in order to fulfill its drilling obligation. See "The Trust—Development Agreement and Drilling Support Lien."

        Under the development agreement, SandRidge is required to adhere to a reasonably prudent operator standard, which requires that it act with respect to the Underlying Properties as it would act with respect to its own properties, disregarding the existence of the royalty interests as burdens affecting such property. Accordingly, SandRidge expects that the average perforated length of future well bores will be generally consistent with the perforated length of the completed Producing Wells and other Mississippian wells outside of the AMI that have been drilled and completed by SandRidge or for its account. However,

Table of Contents

due to the complexity of well completions and future developments in completion technologies, it may be appropriate in some instances to complete longer or shorter wells. The completed Producing Wells and 121 other Mississippian wells outside of the AMI that have been completed by SandRidge have an average perforated length of approximately 4,200 feet.

        SandRidge Exploration and Production, LLC ("SandRidge E&P"), a wholly owned subsidiary of SandRidge, will grant to the trust a lien on its interests in the AMI (except the Producing Wells and any other wells that are already producing and not subject to the royalty interests) in order to secure the estimated amount of the drilling costs for the trust's interests in the Development Wells (the "Drilling Support Lien"). The amount obtained by the trust pursuant to the Drilling Support Lien may not exceed approximately $269.1 million. As SandRidge fulfills its drilling obligation over time, Development Wells that are completed or that are perforated (or made ready to commence stimulation) for completion and then plugged and abandoned will be released from the Drilling Support Lien. After SandRidge has drilled 103 Development Wells, the total dollar amount that may be recovered by the trust for any failure by SandRidge to fulfill its drilling obligation will be proportionately reduced as SandRidge completes the remaining Development Wells. After SandRidge has satisfied its drilling obligation under the development agreement, it may sell, without the consent or approval of the trust unitholders, all or any part of its interest in the Underlying Properties, as long as such sale is subject to and burdened by the royalty interests.

Underlying Properties

        The Underlying Properties are located in Noble, Kay, Alfalfa, Grant and Woods counties in northern Oklahoma and Harper, Comanche, Sumner and Barber counties in southern Kansas in the Mississippian formation, which is an expansive carbonate hydrocarbon system located on the Anadarko Shelf. The top of the formation is encountered between 4,000 feet and 7,000 feet and lies stratigraphically between the Pennsylvanian-aged Morrow formation and the Devonian-aged Woodford Shale formation. The Mississippian formation can reach 1,000 feet in gross thickness and the targeted porosity zone is between 50 and 100 feet in thickness. The formation's geology is well understood as a result of the thousands of vertical wells drilled and produced there since the 1940s, including approximately 73 vertical wells drilled on the Underlying Properties, and over 400 horizontal wells drilled in the region in the Mississippian formation, as discussed below.

        In 2007, the application of horizontal cased-hole drilling and multi-stage hydraulic fracturing treatments demonstrated the potential for extracting significant additional quantities of oil and natural gas from the formation. Since the beginning of 2009, there have been over 400 horizontal wells drilled in the Mississippian formation in northern Oklahoma and southern Kansas, including 205 drilled by SandRidge. From December 31, 2010 to December 31, 2011, the number of SandRidge's producing horizontal wells in the Mississippian formation increased from 44 to 174. As of December 31, 2011, there were approximately 43 horizontal rigs drilling in the formation, with 19 of those rigs drilling for SandRidge. While horizontal wells are more expensive than vertical wells, a horizontal well bore increases the production of hydrocarbons and adds significant recoverable reserves per well. In addition, one horizontal well is the effective equivalent of several vertical wells and, as a result, better returns on drilling investments may be achieved with horizontal drilling.

        As of December 31, 2011, SandRidge had approximately 1.5 million net acres leased in the Mississippian formation in northern Oklahoma and Kansas.

Target Distributions and Subordination and Incentive Thresholds

        SandRidge has calculated quarterly target levels for cash distributions to unitholders for the life of the trust as set forth on Annex B to this prospectus. The amount of actual quarterly distributions may fluctuate from quarter to quarter, depending on the proceeds received by the trust, payments under the hedge

Table of Contents

arrangements, the trust's administrative expenses and other factors. Annex B reflects that while target distributions initially increase as SandRidge completes its drilling obligation and production increases, over time target distributions decline as the rate of production decreases over the life of each well as a result of the depletion of the reserves in the Underlying Properties. The target distributions were derived by assuming that oil and natural gas production from the trust properties will equal the volumes reflected in the reserve report and that prices received for such production will be consistent with monthly NYMEX forward pricing as of January 3, 2012 for the period ending December 31, 2014, and assumed price increases after December 31, 2014 of 2.5% annually, capped at $120.00 per Bbl of oil and $7.00 per MMBtu of natural gas. Using these assumptions, the price of oil would reach the $120.00 per Bbl cap in January 2025, and the price of natural gas would reach the $7.00 per MMBtu cap in September 2031. The target distributions also give effect to estimated post-production expenses and assumed trust general and administrative expenses. While these target distributions do not represent the actual distributions you will receive with respect to your common units, they were used to calculate the subordination and incentive thresholds described in more detail below. For a description of the significant assumptions used to prepare the target distributions, see "Target Distributions and Subordination and Incentive Thresholds—Significant Assumptions Used to Calculate the Target Distributions."

        In order to provide support for cash distributions on the common units, SandRidge has agreed to subordinate 12,062,500 of the trust units it will retain following this offering, which will constitute 25% of the total trust units outstanding. The subordinated units will be entitled to receive pro rata distributions from the trust each quarter if and to the extent there is sufficient cash to provide a cash distribution on the common units that is no less than the applicable quarterly subordination threshold. If there is not sufficient cash to fund such a distribution on all of the common units, the distribution to be made with respect to the subordinated units will be reduced or eliminated for such quarter in order to make a distribution, to the extent possible, of up to the subordination threshold amount on all the common units, including the common units held by SandRidge. Each quarterly subordination threshold is 20% below the target distribution level for the corresponding quarter (each, a "subordination threshold").

        In exchange for agreeing to subordinate a majority of its trust units, and in order to provide additional financial incentive to SandRidge to satisfy its drilling obligation and perform operations on the Underlying Properties in an efficient and cost-effective manner, SandRidge will be entitled to receive incentive distributions equal to 50% of the amount by which the cash available for distribution on all of the trust units in any quarter is 20% greater than the target distribution for such quarter (each, an "incentive threshold"). The remaining 50% of cash available for distribution in excess of the incentive thresholds will be paid to trust unitholders, including SandRidge, on a pro rata basis.

        By way of example, if the target distribution per unit for a particular quarterly period is $.50, then the subordination threshold would be $.40 and the incentive threshold would be $.60 for such quarter. This means that if the cash available for distribution to all holders for that quarter would result in a per unit distribution below $.40, the distribution to be made with respect to subordinated units will be reduced or eliminated in order to make a distribution, to the extent possible, up to the amount of the subordination threshold, on the common units. If, on the other hand, the cash available for distribution to all holders would result in a per unit distribution above $.60, then SandRidge would receive 50% of the amount by which the cash available for distribution on all the trust units exceeds $.60, with all trust unitholders (including SandRidge on a pro rata basis) sharing in the other 50% of such excess amount. See "Target Distributions and Subordination and Incentive Thresholds."

        At the end of the fourth full calendar quarter following SandRidge's satisfaction of its drilling obligation with respect to the Development Wells, the subordinated units will automatically convert into common units on a one-for-one basis and SandRidge's right to receive incentive distributions will terminate. After such time, the common units will no longer have the protection of the subordination threshold, and all trust unitholders will share on a pro rata basis in the trust's distributions. SandRidge currently expects that it will complete its drilling obligation on or before December 31, 2015 and that,

accordingly, the subordinated units will convert into common units on or before December 31, 2016. SandRidge is obligated to complete its drilling obligation by December 31, 2016, in which event the subordinated units would convert into common units on or before December 31, 2017. The period during which the subordinated units are outstanding is referred to as the "subordination period."

        SandRidge's management has prepared the prospective financial information set forth below to present the target distributions to the holders of the trust units based on the estimates and assumptions described under "Target Distributions and Subordination and Incentive Thresholds." The accompanying prospective financial information was not prepared with a view toward complying with the guidelines of the U.S. Securities and Exchange Commission ("SEC") or the guidelines established by the American Institute of Certified Public Accountants with respect to preparation and presentation of prospective financial information. More specifically, such information omits items that are not relevant to the trust. SandRidge's management believes the prospective financial information was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of management's knowledge and belief, the expected course of action and the expected future financial performance of the royalty interests. However, this information is based on estimates and judgments, and readers of this prospectus are cautioned not to place undue reliance on the prospective financial information.

        The prospective financial information included in this prospectus has been prepared by, and is the responsibility of, SandRidge's management. PricewaterhouseCoopers LLP, the trust's and SandRidge's independent registered public accountant, has not examined, compiled or performed any procedures with respect to the accompanying prospective financial information and, accordingly, PricewaterhouseCoopers LLP expresses no opinion or any other form of assurance with respect thereto. The reports of PricewaterhouseCoopers LLP included in this prospectus relate to the Statement of Assets and Trust Corpus of the trust and the historical Statement of Revenues and Direct Operating Expenses of the Underlying Properties. The foregoing reports do not extend to the prospective financial information and should not be read to do so.

        The following table sets forth the target distributions and subordination and incentive thresholds for each calendar quarter through the fourth quarter of 2017. The effective date of the conveyance of the royalty interests is January 1, 2012, which means that the trust will be credited with the proceeds of production attributable to the royalty interests from that date even though the trust properties will not be conveyed to the trust until the closing of this offering. Please see "—Calculation of Target Distributions" below. The first distribution, which will cover the first quarter of 2012, is expected to be made on or about May 30, 2012 to record unitholders as of May 15, 2012. Due to the timing of the payment of production proceeds to the trust, the trust expects that the first distribution will include sales for oil and natural gas for two months. Thereafter, quarterly distributions will generally include royalties attributable to sales of oil and natural gas for three months, including one month of the prior quarter. The trustee intends to

Calculation of Target Distributions

        The following table presents the calculation of the target distributions for each quarter through and including the quarter ending December 31, 2012. The target distributions were prepared by SandRidge based on assumptions of production volumes, pricing and other factors. The production forecasts used to calculate target distributions are based on estimates by Netherland Sewell. Payments to unitholders will generally be made 60 days following each calendar quarter. SandRidge will make payments to the trust that will include cash from production from the first two months of the quarter just ended as well as the last month of the immediately preceding quarter. Actual cash distributions to the trust unitholders will fluctuate quarterly based on the quantity of oil and natural gas produced from the Underlying Properties, the prices received for oil and natural gas production, the trust's hedging arrangements and other factors. Please read "Target Distributions and Subordination and Incentive Thresholds—Significant Assumptions Used to Calculate the Target Distributions."

        On a pro forma basis, cash available for distribution was $16.6 million for the nine-month period ended September 30, 2011. See "Unaudited Pro Forma Financial Information."

Key Investment Considerations

        The following are some key investment considerations related to the Underlying Properties, the royalty interests and the common units:

Table of Contents

Proved and Probable Reserves

        Proved and Probable Reserves of Underlying Properties and Royalty Interests.    The following table sets forth estimated proved and probable reserves and the PV-10 value as of December 31, 2011 attributable to the Underlying Properties, the PDP Royalty Interest and the Development Royalty Interest, in each case derived from the reserve report. The reserve report was prepared by Netherland Sewell in accordance with criteria established by the SEC. A summary of the reserve report is included as Annex A to this prospectus.

        Reserve quantities attributable to the royalty interests are calculated by multiplying the gross reserves for each property by the royalty interest assigned to the trust in each property. The reserves related to the Underlying Properties include all of the proved and probable reserves expected to be economically produced during the life of the properties. The reserves and revenues attributable to the trust's interests include only the reserves attributable to the Underlying Properties that are expected to be produced within the 20-year period in which the trust owns the Term Royalties as well as the residual interest in the reserves that the trust will own on the Termination Date.

        Proved reserves are reserves that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward from known reservoirs under existing economic conditions, operating methods and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain. Probable reserves are reserves that are less certain to be recovered than proved reserves but that, together with proved reserves, are at least as likely as not to be recovered. Estimates of probable reserves are less certain than estimates of proved reserves and are subject to substantially greater risk of not actually being realized. With respect to the Underlying Properties, and subject to the criteria described above, the proved reserves are limited to productive units and undeveloped offset units, and the probable reserves are limited to step-out units from the proved units. There are 67 Producing Wells and 122 Development Well locations attributable to proved undeveloped, or "PUD," reserves or 1.8 Development Well locations attributable to PUD reserves for every Producing Well. There are 84 Development Well locations attributable to probable reserves or 1.3 Development Well locations attributable to probable reserves for every Producing Well. For a discussion of the uncertainties associated with estimates of probable reserves, see "Risk Factors—Actual reserves and future production may be less than current estimates, which could reduce cash distributions by the trust and the value of the trust units."

        Estimates of reserves are also continually subject to revisions based on production history, results of additional exploration and development, price changes, and other factors. See "The Underlying Properties—Oil and Natural Gas Reserves" and "The Underlying Properties—The Reserve Report" for information about the estimated reserves attributable to the trust and a discussion of the methods used to estimate such reserves and the allocation of proved and probable reserves to the trust.

The proved and probable reserves were determined using a 12-month unweighted arithmetic average of the first-day-of-the-month prices for oil and natural gas for the period from December 31, 2010 through December 31, 2011, without giving effect to derivative transactions, and were held constant

The prices used in the reserve report, as well as SandRidge's internal reports, yield weighted average prices at the wellhead, which are based on first-day-of-the-month reference prices and adjusted for transportation and regional price differentials. The reference prices and the equivalent weighted average wellhead prices are both presented in the table below.

PV-10 is the present value of estimated future net revenue to be generated from the production of proved or probable reserves, discounted using an annual discount rate of 10%, calculated without deducting future income taxes. PV-10 is a non-GAAP financial measure and generally differs from standardized measure of discounted net cash flows, or Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. Because the historical financial information related to the Underlying Properties consists solely of revenues and direct operating expenses and does not include the effect of income taxes, we expect the PV-10 and Standardized Measure attributable to the Underlying Properties to be equivalent. Because the trust will not bear federal income tax expense, we also expect the PV-10 and Standardized Measure attributable to the royalty interests to be equivalent. Neither PV-10 nor Standardized Measure represents an estimate of the fair market value of the Underlying Properties or the royalty interests. SandRidge and others in the industry use PV-10 as a measure to compare the relative size and value of proved and probable reserves held by companies without regard to the specific tax characteristics of such entities. PV-10 for the royalty interests has been calculated without deduction for production and development costs, as the trust will not bear those costs.

See "The Trust—Formation Transactions."

Total units outstanding after the offering

 

48,250,000 trust units, consisting of 36,187,500 common units and 12,062,500 subordinated units

Over-allotment option

 

3,750,000 common units will be issued and retained by the trust at the initial closing, to be used to satisfy (if necessary) the over-allotment option granted to the underwriters. If the over-allotment option is exercised, the trust will sell to the underwriters such number of the retained units as is necessary to satisfy the over-allotment option, and will then deliver the net proceeds of such sale, together with any remaining unsold units, to SandRidge (or a SandRidge subsidiary) as partial consideration for the conveyance of the Perpetual Royalties. If the over-allotment option is not exercised by the underwriters, the retained units will be delivered to SandRidge (or a SandRidge subsidiary), as partial consideration for the conveyance of the Perpetual Royalties, promptly following the 30th day after the initial closing.

Directed unit program

 

The underwriters have reserved up to 5% of the common units being offered by this prospectus for sale to SandRidge's directors, officers, and certain other persons associated with SandRidge, at the initial public offering price. The sales will be made by Morgan Stanley & Co. LLC through a directed unit program. See "Underwriters—Directed Unit Program."

Use of proceeds

 

The trust is offering the common units to be sold in this offering. Assuming no exercise of the underwriters' over-allotment option and an initial public offering price of $        per common unit, the estimated net proceeds of this offering will be approximately $       million, after deducting underwriting discounts and commissions and offering expenses. The trust will deliver the net proceeds to one or more wholly-owned subsidiaries of SandRidge as part of the consideration for the conveyance of the royalty interests. See "The Trust—Formation Transactions."

 

SandRidge intends to use the offering proceeds, including proceeds from any exercise of the underwriters' over-allotment option, for general corporate purposes, which may include the funding of the drilling obligation.

Quarterly cash distributions

 

Quarterly cash distributions during the term of the trust will be made by the trustee on or about the 60th day following the end of each calendar quarter to unitholders of record on or about the 45th day following each calendar quarter. The first distribution, which will cover the first quarter of 2012, is expected to be made on or about May 30, 2012 to record unitholders as of May 15, 2012. Due to the timing of the payment of production proceeds to the trust, the trust expects that the first distribution will include sales for oil and natural gas for two months. The trustee intends to withhold $1.0 million from the first distribution to establish a cash reserve available for trust administrative expenses.

 

Actual cash distributions to the trust unitholders will fluctuate quarterly based on the quantity of oil and natural gas produced from the Underlying Properties, the prices received for oil and natural gas production, the trust's hedging arrangements and other factors. Because payments to the trust will be generated by depleting assets and production from the Underlying Properties will diminish over time, a portion of each distribution will represent a return of your original investment. Given that the production from the Underlying Properties is expected to initially increase and then subsequently decline over time, the target distributions are also expected to initially increase before declining over time.

Voting rights in the trust

 

Matters voted on by trust unitholders will generally be subject to approval by holders of a majority of the common units (excluding common units owned by SandRidge and its affiliates) and holders of a majority of the trust units, in each case voting in person or by proxy at a meeting of such holders at which a quorum is present. SandRidge will not be entitled to vote on the removal of the trustee or appointment of a successor trustee. However, at any time SandRidge and its affiliates own less than 10% of the total trust units outstanding, matters voted on by trust unitholders will be subject to approval by a majority of the trust units, including units owned by SandRidge, voting in person or by proxy at a meeting of such holders at which a quorum is present.

Termination of the trust

 

The trust will dissolve and begin to liquidate on the Termination Date, which is December 31, 2031, and will soon thereafter wind up its affairs and terminate. At the Termination Date, the Term Royalties will revert automatically to SandRidge. The Perpetual Royalties will be retained by the trust at the Termination Date and thereafter sold, and the net proceeds of the sale, as well as any remaining trust cash reserves, will be distributed to the unitholders in accordance with their interests. SandRidge will have a right of first refusal to purchase the Perpetual Royalties after the Termination Date.

Table of Contents

U.S. federal income tax considerations

 

The trust will be treated as a partnership for U.S. federal income tax purposes. Consequently, the trust will not incur any U.S. federal income tax liability. Instead, trust unitholders will be allocated an amount of the trust's income, gain, loss or deductions corresponding to their interest in the trust, which amounts may differ in timing or amount from actual distributions.

 

The Term PDP Royalty will, and the Term Development Royalty should, be treated as debt instruments for U.S. federal income tax purposes. The trust will be required to treat a portion of each payment it receives with respect to each such royalty interest as interest income in accordance with the "noncontingent bond method" under the original issue discount rules contained in the Internal Revenue Code of 1986, as amended, and the corresponding IRS regulations.

 

The Perpetual PDP Royalty and the Perpetual Development Royalty will be granted on a perpetual basis. The Perpetual PDP Royalty will, and the Perpetual Development Royalty should, be treated as mineral royalty interests for U.S. federal income tax purposes, generating ordinary income subject to depletion.

 

The terms "Term PDP Royalty," "Term Development Royalty," "Perpetual PDP Royalty," and "Perpetual Development Royalty" as used above are defined in "The Trust—Formation Transactions."

 

Please read "U.S. Federal Income Tax Considerations" for more information.

Estimated ratio of taxable income to distributions

 

SandRidge estimates that if you own the units you purchase in this offering through the record date for distributions for the period ending December 31, 2014, you will be allocated, on a cumulative basis, an amount of federal taxable income for that period that will be approximately        % of the cash distributed to you with respect to that period. For example, if you receive an annual distribution of $        per unit, the trust estimates that your average allocable federal taxable income per year will be approximately $        per unit.

        You should carefully consider the risks described below before making an investment decision. The trust's cash available for distribution could be materially adversely affected by any of these risks. The trading price of the common units could decline due to any of these risks, or you may lose all or part of your investment.

Risks Related to the Units

         Drilling for and producing oil and natural gas on the Underlying Properties are high risk activities with many uncertainties that could delay or change the anticipated drilling schedule for the Development Wells and adversely affect future production from the Underlying Properties. Any such delays or reductions in production could decrease cash that is available for distribution to unitholders.

        The drilling and completion of the Development Wells are subject to numerous risks beyond SandRidge's and the trust's control, including risks that could delay or change the current drilling schedule for the Development Wells and the risk that drilling will not result in commercially viable oil and natural gas production. Drilling for oil and natural gas can be unprofitable if dry wells are drilled and if productive wells do not produce sufficient revenues to return a profit. SandRidge's and any third-party operators' decisions to develop or otherwise exploit certain areas within the AMI will depend in part on the evaluation of data obtained through geophysical and geological analyses, production data and engineering studies, the results of which are often inconclusive or subject to varying interpretations. The estimated costs of drilling, completing and operating wells are uncertain before drilling commences. Overruns in budgeted expenditures are common risks that can make a particular project uneconomical. A Development Well that is successfully completed may not pay out the capital costs spent to drill it. Drilling and production operations on the Underlying Properties may be curtailed, delayed or canceled as a result of various factors, including the following:

20


Table of Contents

        In the event that drilling of the Development Wells is delayed or the Producing Wells or Development Wells have lower than anticipated production due to one of the factors above, or for any other reason, cash distributions to unitholders may be reduced. In addition, wells drilled in the Mississippian formation in the AMI typically produce a large volume of water, which requires the drilling of saltwater disposal wells. SandRidge's inability to drill these wells or otherwise dispose of the water produced from the Producing Wells and Development Wells in an efficient manner could delay production and therefore the trust's receipt of proceeds from the royalty interests. Under the Development Agreement, SandRidge will receive credit for drilling a Development Well if the well is drilled in the AMI and perforated (or made ready to commence stimulation) horizontally for completion in the Mississippian formation, even if such well does not successfully produce hydrocarbons.

         Oil and natural gas prices fluctuate due to a number of factors that are beyond the control of the trust and SandRidge, and lower prices could reduce proceeds to the trust and cash distributions to unitholders.

        The trust's reserves and quarterly cash distributions are highly dependent upon the prices realized from the sale of oil and natural gas. The markets for these commodities are very volatile. Oil and natural gas prices can fluctuate widely in response to a variety of factors that are beyond the control of the trust and SandRidge. These factors include, among others:

        For oil, from January 1, 2008 through December 31, 2011, the highest monthly NYMEX settled price was $140.00 per Bbl and the lowest was $41.68 per Bbl. For natural gas, from January 1, 2008 through December 31, 2011, the highest monthly NYMEX settled price was $13.11 per MMBtu and the lowest was $2.84 per MMBtu. In addition, the market price of oil and natural gas is generally higher in the winter months than during other months of the year due to increased demand for oil and natural gas for heating purposes during the winter season.

        Lower oil and natural gas prices will reduce proceeds to which the trust is entitled and may ultimately reduce the amount of oil and natural gas that is economic to produce from the Underlying Properties. As a result, SandRidge or any third-party operator of any of the Underlying Properties could determine during periods of low oil and natural gas prices to shut in or curtail production from wells on the Underlying

21


Table of Contents

Properties. In addition, the operator of the Underlying Properties could determine during periods of low oil and natural gas prices to plug and abandon marginal wells that otherwise may have been allowed to continue to produce for a longer period under conditions of higher prices. Specifically, SandRidge or any third party operator may abandon, at its cost, any well or property if it reasonably believes that the well or property can no longer produce oil and natural gas in commercially economic quantities. This could result in termination of the portion of the royalty interest relating to the abandoned well or property, and SandRidge would have no obligation to drill a replacement well. In addition, lower oil and natural gas prices could make it more likely that leases in the undeveloped acreage will expire at the end of their respective primary terms as a result of the failure to establish production from such leasehold acreage in commercially paying quantities prior to such date. The volatility of oil and natural gas prices also reduces the accuracy of target distributions to trust unitholders. For a discussion of certain risks related to the trust's hedging arrangements, see "—The hedging arrangements for the trust will cover only a portion of the production attributable to the trust, and such arrangements will limit the trust's ability to benefit from commodity price increases for hedged volumes above the corresponding hedge price."

         Actual reserves and future production may be less than current estimates, which could reduce cash distributions by the trust and the value of the trust units.

        The value of the trust units and the amount of future cash distributions to the trust unitholders will depend upon, among other things, the accuracy of the reserves estimated to be attributable to the trust's royalty interests. It is not possible to measure underground accumulations of oil and natural gas in an exact way, and estimating reserves is inherently uncertain. Further, estimates of probable reserves are, by definition, less certain than estimates of proved reserves and are subject to substantially greater risk of not actually being realized. As discussed below, the process of estimating oil and natural gas reserves requires interpretations of available technical data and many assumptions. Any significant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves shown in this prospectus. This could result in actual production and revenues for the Underlying Properties being materially less than estimated amounts.

        In order to prepare the estimates of reserves attributable to the Underlying Properties and the trust, SandRidge and the trust must project production rates and the timing of development expenditures. In so doing, SandRidge and the trust must analyze available geological, geophysical, production and engineering data. The extent, quality and reliability of this data can vary.

        In addition, petroleum engineers are required to make subjective estimates of underground accumulations of oil and natural gas based on factors and assumptions that include:

        Changes in these assumptions or actual production costs incurred and results of actual development could materially decrease reserve estimates and, because they are inherently less certain than proved reserves, this variability is likely to be higher for probable reserves estimates.

        Estimates of reserves are also continually subject to revisions based on production history, results of additional exploration and development, price changes, and other factors. See "The Underlying Properties—Oil and Natural Gas Reserves" and "The Underlying Properties—The Reserve Report" for information about the estimated reserves attributable to the trust and a discussion of the methods used to estimate such reserves and the allocation of proved and probable reserves to the trust.

        Reserve estimates for fields that do not have a lengthy production history are less reliable than estimates for fields with lengthy production histories. Less production history may contribute to less accurate estimates of reserves, future production rates and the timing of development expenditures. Most

Table of Contents

of the Producing Wells have been operational for less than one year and estimated reserves vary substantially from well to well and are not directly correlated to perforated lateral length or completion technique. Historical production data from vertical wells drilled in the AMI analyzed by SandRidge and Netherland Sewell may not accurately predict future production from horizontal wells. The lack of operational history for horizontal wells in the Mississippian formation may also contribute to the inaccuracy of estimates of reserves. A material and adverse variance of actual production, revenues and expenditures from those underlying reserve estimates would have a material adverse effect on the financial condition, results of operations and cash flows of the trust and would reduce cash distributions to trust unitholders. As with all horizontal drilling programs, there is a risk that some or all of a horizontal well could miss the target reservoir. As a result, you may not receive the benefit of the total amount of reserves reflected in the reserve report, notwithstanding the fact that SandRidge has satisfied its drilling obligation. See "Summary—The Development Wells."

         In certain circumstances the trust may have to make cash payments under the hedging arrangements and these payments could be significant; such arrangements will be secured by the trust's royalty interests in the Underlying Properties.

        If actual production is below the amounts forecast in the reserve report and oil prices rise, the hedging arrangements entered into by the trust may result in the trust having to make cash payments under the hedging arrangements which could, in certain circumstances, be significant. Swap contracts underlying the derivatives agreement between SandRidge and the trust and swap contracts entered into between the trust and unaffiliated hedge counterparties provide the trust with the right to receive from SandRidge or the hedge counterparties, as applicable, the excess of the fixed price specified in the hedge contract over a floating market price, multiplied by the volume of production hedged. If the floating market price exceeds the specified fixed price, the trust must pay SandRidge or its hedge counterparties, as applicable, this difference in price multiplied by the volume of production hedged, even if the production attributable to the trust's royalty interests is insufficient to cover the volume of production specified in the applicable hedge contracts. Accordingly, if the production attributable to the trust's royalty interests is less than the volume hedged and the floating market price exceeds the specified fixed price, the trust will have to make payments against which it will have insufficient offsetting cash receipts from the sale of production attributable to its royalty interests. Furthermore, if one or more of the purchasers of the production attributable to the Underlying Properties defaults on a payment obligation, the trust may have insufficient cash receipts to make payments under the hedging arrangements. If these payments become too large, the trust's liquidity and cash available for distribution may be adversely affected.

        In addition, the trust's obligations to the counterparties under its direct hedge contracts will be secured by a first priority lien on the trust's royalty interests in the Underlying Properties. If the trust fails to make any required payments to its unaffiliated hedge counterparties, these counterparties will have a right to foreclose on the trust's royalty interests and may sell the trust's royalty interests in order to satisfy the trust's payment obligations. Following foreclosure by the hedging counterparties, the counterparties may not be able to secure a replacement operator and any amounts recovered in such foreclosure action would not result in any distribution to the trust unitholders. In addition, the trust's hedging arrangements will contain a prohibition on the trust granting additional liens on any of its properties, other than customary permitted liens and liens in favor of the trustees of the trust. Please see "The Trust—Hedging Arrangements" for more details on the prices and production volumes associated with the trust's hedging arrangements.

         Estimates of the target distributions to unitholders, subordination thresholds and incentive thresholds are based on assumptions that are inherently subjective and are subject to significant business, economic, financial, legal, regulatory and competitive risks and uncertainties that could cause actual cash distributions to differ materially from those estimated.

        The estimates of target distributions to unitholders, subordination thresholds and incentive thresholds, as set forth in this prospectus, are based on SandRidge's calculations, and SandRidge has not

23


Table of Contents

received an opinion or report on such calculations from any independent accountants, financial advisers, or engineers. Such calculations are based on assumptions about drilling, production, oil and natural gas prices, hedging activities, capital expenditures, expenses, tax rates and production tax credits under state law, the location of Development Wells, and other matters that are inherently uncertain and are subject to significant business, economic, financial, legal, regulatory and competitive risks and uncertainties that could cause actual results to differ materially from those estimated. For example, these estimates have assumed that oil and natural gas production is sold at prices consistent with monthly NYMEX forward pricing as of January 3, 2012 for the period ending December 31, 2014, and assumed price increases after December 31, 2014 of 2.5% annually, capped at $120.00 per Bbl of oil in January 2025 and $7.00 per MMBtu of natural gas in September 2031; however, actual sales prices may be significantly lower. Additionally, these estimates assume that the Development Wells will be drilled on SandRidge's current anticipated schedule at the locations referenced in the reserve report and that the related Underlying Properties will achieve production volumes set forth in the reserve report; however, the drilling of the Development Wells may be delayed. Development Wells may be drilled at locations with higher post-production expenses and applicable taxes and actual production volumes may be significantly lower than estimated. Further, after wells are completed, production operations may be curtailed, delayed or terminated as a result of a variety of risks and uncertainties, including those described above under "—Drilling for and producing oil and natural gas on the Underlying Properties are high risk activities with many uncertainties that could delay the anticipated drilling schedule for the Development Wells and adversely affect future production from the Underlying Properties. Any such delays or reductions in production could decrease cash that is available for distribution to unitholders."

        Furthermore, neither the target distribution nor the subordination threshold for each quarter during the subordination period necessarily represents the actual cash distributions you will receive. To the extent actual production volumes or sales prices of oil and natural gas differ from the assumptions used to generate the target distributions, the actual distributions you receive may be lower than the target distribution and the subordination threshold for the applicable quarter. A cash distribution to trust unitholders below the target distribution amount or the subordination threshold may materially adversely affect the market price of the trust units.

         The subordination of certain trust units held by SandRidge does not assure that you will in fact receive any specified return on your investment in the trust.

        Although SandRidge will not be entitled to receive any distribution on its subordinated units unless there is enough cash for all of the common units to receive a distribution equal to the subordination threshold for such quarter (which is 20% below the target distribution level for the corresponding quarter), the subordinated units constitute only a 25% interest in the trust, and this feature does not guarantee that common units will receive a distribution equal to the subordination threshold, or any distribution at all. Additionally, the subordination period will terminate and the subordinated units will automatically convert into common units on a one-for-one basis, following which they will no longer be subject to the subordination threshold, at the end of the fourth full calendar quarter following SandRidge's satisfaction of its drilling obligation with respect to the Development Wells.

        Quarterly cash distributions will be made by the trust based on the proceeds received by the trust pursuant to the royalty interests for the preceding calendar quarter. If a quarterly cash distribution is lower than the target distribution amount or subordination threshold set forth in this prospectus for any quarter, the common units will not be entitled to receive any additional distributions nor will the units be entitled to arrearages in any future quarter.

         The historical and pro forma financial information included in this prospectus may not be representative of the trust's future distributable income.

        The historical financial information for the Underlying Properties included in this prospectus is derived from SandRidge's historical financial statements for periods prior to the trust's initial public

offering without giving effect to the terms and conditions of the royalty interests and, as a result, does not reflect what the trust's distributable income will be in the future.

        In preparing the pro forma statement of distributable income included in this prospectus, SandRidge has made adjustments to the historical financial information for the Underlying Properties based upon currently available information and upon assumptions that SandRidge's management believes are reasonable in order to reflect, on a pro forma basis, the impact of the conveyance of the royalty interests to the trust and the other items discussed in the unaudited pro forma financial statement and related notes. The estimates and assumptions used in the calculation of the pro forma financial information in this prospectus may be materially different from the trust's actual experience. Accordingly, the pro forma financial information included in this prospectus does not purport to represent what the trust's distributable income would actually have been had it been in operation during the periods presented or what the trust's distributable income will be in the future, nor does the pro forma financial information give effect to any events other than those discussed in the unaudited pro forma financial statement and related notes.

         Shortages or increases in costs of equipment, services and qualified personnel could delay the drilling of the Development Wells and result in a reduction in the amount of cash available for distribution.

        The demand for qualified and experienced personnel to conduct field operations, geologists, geophysicists, engineers and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with oil and natural gas prices, causing periodic shortages. Historically, there have been shortages of drilling rigs and other equipment as demand for rigs and equipment has increased along with the number of wells being drilled. These factors also cause significant increases in costs for equipment, services and personnel. Higher oil and natural gas prices generally stimulate demand and result in increased prices for drilling rigs, crews and associated supplies, equipment and services. Shortages of field personnel and equipment or price increases could significantly hinder SandRidge's ability to perform the drilling obligation and delay completion of the Development Wells, which would reduce future distributions to trust unitholders.

         Due to the trust's lack of industry and geographic diversification, adverse developments in the trust's existing area of operation could adversely impact its financial condition, results of operations and cash flows and reduce its ability to make distributions to the unitholders.

        The Underlying Properties will be operated for oil and natural gas production only and are focused exclusively in the Mississippian formation in northern Oklahoma and southern Kansas. This concentration exposes the trust's interests to operational and regulatory risk in that area. Due to the lack of diversification in industry type and location of the trust's interests, adverse developments in the oil and natural gas market or the area of the Underlying Properties, including, for example, transportation or treatment capacity constraints, curtailment of production or treatment plant closures for scheduled maintenance, could have a significantly greater impact on the trust's financial condition, results of operations and cash flows than if the trust's royalty interests were more diversified.

         The generation of proceeds for distribution by the trust depends in part on access to and the operation of gathering, transportation and processing facilities. Limitations in the availability of those facilities could interfere with sales of oil and natural gas production from the Underlying Properties.

        The amount of oil and natural gas that may be produced and sold from any well to which the Underlying Properties relate is subject to curtailment in certain circumstances, such as by reason of weather conditions, pipeline interruptions due to scheduled and unscheduled maintenance, failure of tendered oil and natural gas to meet quality specifications of gathering lines or downstream transporters, excessive line pressure which prevents delivery, physical damage to the gathering system or transportation system or lack of contracted capacity on such systems. The curtailments may vary from a few days to several months. In many cases, SandRidge is provided limited notice, if any, as to when production will be curtailed and the duration of such curtailments. If SandRidge is forced to reduce production due to such a

25


Table of Contents

curtailment, the revenues of the trust and the amount of cash distributions to the trust unitholders would similarly be reduced due to the reduction of proceeds from the sale of production.

        Some of the Development Wells on the Underlying Properties may be drilled in locations that currently are not serviced by natural gas gathering and transportation pipelines or locations in which existing gathering and transportation pipelines do not have sufficient capacity to transport additional production. As a result, SandRidge may not be able to sell the natural gas production from certain Development Wells until the necessary gathering systems and/or transportation pipelines are constructed or until the necessary transportation capacity on an interstate pipeline is obtained. In particular, the system SandRidge intends to use to compress and process the natural gas produced from certain of the Underlying Properties could be near its capacity and may not be able to process all of SandRidge's gas. Any delay in the expansion of such system or the construction or expansion of any other natural gas gathering systems beyond the currently estimated construction schedules, or a delay in the procurement of additional transportation capacity would delay the receipt of any proceeds that may be associated with the natural gas production from the Development Wells.

         Title deficiencies with respect to the Underlying Properties could adversely affect SandRidge's rights to production from the Underlying Properties.

        The existence of title deficiencies with respect to the Underlying Properties could reduce the value or render properties worthless, thus adversely affecting the distributions to unitholders. SandRidge does not obtain title insurance covering oil, gas and mineral leaseholds. Additionally, undeveloped leasehold acreage has greater risk of title defects than developed acreage.

        SandRidge has not necessarily obtained drilling title opinions on all of the Underlying Properties. Prior to drilling of a Development Well, SandRidge intends to obtain a drilling title opinion to identify defects in title to the leasehold. Frequently, as a result of title examinations, certain curative work may be required to correct identified title defects, and such curative work entails time and expense. SandRidge's inability or failure to cure title defects could render some locations undrillable or cause SandRidge to lose its rights to some or all production from some of the Underlying Properties, which could result in a reduction in proceeds available for distribution to unitholders and the value of the trust units if a comparable additional location to drill a Development Well cannot be identified.

         The trust is passive in nature and will have no voting rights in SandRidge, managerial, contractual or other ability to influence SandRidge, or control over the field operations of, sale of oil and natural gas from, or development of, the Underlying Properties.

        Trust unitholders have no voting rights with respect to SandRidge and, therefore, will have no managerial, contractual or other ability to influence SandRidge's activities or operations of the Underlying Properties. In addition, some of the Development Wells may be operated by third parties unrelated to SandRidge. Such third party operators may not have the operational expertise of SandRidge within the AMI. Oil and natural gas properties are typically managed pursuant to an operating agreement among the working interest owners in the properties. The typical operating agreement contains procedures whereby the owners of the aggregate working interest in the property designate one of the interest owners to be the operator of the property. Under these arrangements, the operator is typically responsible for making all decisions relating to drilling activities, sale of production, compliance with regulatory requirements and other matters that affect the property. The failure of an operator to adequately perform operations could reduce production from the Underlying Properties and cash available for distribution to unitholders. Neither the trustee nor the trust unitholders has any contractual ability to influence or control the field operations of, sale of oil and natural gas from, or future development of, the Underlying Properties.

Table of Contents

         The oil and natural gas reserves estimated to be attributable to the Underlying Properties of the trust are depleting assets and production from those reserves will diminish over time. Furthermore, the trust is precluded from acquiring other oil and gas properties or royalty interests to replace the depleting assets and production.

        The proceeds payable to the trust from the royalty interests are derived from the sale of the production of oil and natural gas from the Underlying Properties. The oil and natural gas reserves attributable to the Underlying Properties are depleting assets, which means that the reserves of oil and natural gas attributable to the Underlying Properties will decline over time as will the quantity of oil and natural gas produced from the Underlying Properties.

        Future maintenance may affect the quantity of proved reserves that can be economically produced from the Underlying Properties to which the wells relate. The timing and size of these projects will depend on, among other factors, the market prices of oil and natural gas. With the exception of SandRidge's commitment to drill the Development Wells, SandRidge has no contractual obligation to make capital expenditures on the Underlying Properties in the future. Furthermore, for properties on which SandRidge is not designated as the operator, SandRidge has no control over the timing or amount of those capital expenditures. SandRidge also has the right to non-consent and not participate in the capital expenditures on properties for which it is not the operator, in which case SandRidge and the trust will not receive the production resulting from such capital expenditures. If SandRidge or other operators of the wells to which the Underlying Properties relate do not implement maintenance projects when warranted, the future rate of production decline of proved reserves may be higher than the rate currently expected by SandRidge or estimated in the reserve report.

        The trust agreement will provide that the trust's business activities will generally be limited to owning the royalty interests and entering into the hedging arrangements and activities reasonably related thereto, including activities required or permitted by the terms of the conveyances related to the royalty interests. As a result, the trust will not be permitted to acquire other oil and gas properties or royalty interests to replace the depleting assets and production attributable to the trust.

         An increase in the differential between the price realized by SandRidge for oil and natural gas produced from the Underlying Properties and the NYMEX or other benchmark price of oil or natural gas could reduce the proceeds to the trust and therefore the cash distributions by the trust and the value of trust units.

        The prices received for SandRidge's oil and natural gas production usually fall below benchmark prices such as NYMEX. The difference between the price received and the benchmark price is called a differential. The amount of the differential will depend on a variety of factors, including discounts based on the quality and location of hydrocarbons produced, Btu content and post-production costs. These factors can cause differentials to be volatile from period to period. SandRidge has little or no control over the factors that determine the amount of the differential, and cannot accurately predict differentials for natural gas or crude oil. Increases in the differential between the realized price of oil or natural gas and the benchmark price for oil or natural gas could reduce the proceeds to the trust and therefore the cash distributions made by the trust and the value of the trust units. The estimated realized prices for natural gas used to prepare the target distributions are the NYMEX futures prices for natural gas, and the estimated realized prices for oil used to prepare the target distributions assume a $5.03 per barrel negative differential from the NYMEX futures prices for oil. For more information on the differentials assumed for purposes of preparing the target distributions, see "Target Distributions and Subordination and Incentive Thresholds—Significant Assumptions Used to Calculate the Target Distributions."

27


Table of Contents

         The amount of cash available for distribution by the trust will be reduced by post-production costs and applicable taxes associated with the trust's royalty interests, trust expenses and incentive distributions payable to SandRidge.

        The amount of post-production costs, taxes, expenses borne by the trust and incentive distributions payable to SandRidge may vary materially from quarter-to-quarter. The extent by which the costs and expenses of the trust are higher or lower in any quarter will directly decrease or increase the amount received by the trust and available for distribution to the unitholders. For a further summary of post-production costs and applicable taxes for the producing lives of the Producing Wells and Development Wells, see "The Underlying Properties." Historical post-production costs and taxes, however, may not be indicative of future post-production costs and taxes.

         The hedging arrangements for the trust will cover only a portion of the production attributable to the trust, and such arrangements will limit the trust's ability to benefit from commodity price increases for hedged volumes above the corresponding hedge price.

        Under the trust's hedging arrangements, approximately            % of the expected production and approximately            % of the expected revenues upon which the target distributions are based from                        through                         will be hedged. The remaining estimated production of oil during that time, all production of natural gas during that time, and all production after such time will not be hedged. With respect to unhedged volumes and periods, the trust will not be protected against the price risks inherent in holding interests in oil and natural gas, commodities that are frequently characterized by significant price volatility. Furthermore, while the use of hedging arrangements limits the downside risk of price declines, they may also limit the trust's ability to benefit from increases in oil prices above the hedge price on the portion of the production attributable to the trust's royalty interests that is hedged.

        The trust's receipt of any payments due to it based on the trust's hedge contracts with unaffiliated hedge counterparties and the derivatives agreement with SandRidge depends upon the financial position of the trust's unaffiliated hedging counterparties, SandRidge and SandRidge's hedging counterparties. The trust's counterparties under its hedge contracts with unaffiliated third parties will be institutions with a corporate credit rating of at least A-/A3 as rated by Standard & Poor's or Moody's. The trust's counterparty under the derivatives agreement is SandRidge, whose counterparties will also be institutions with a corporate credit rating of at least A-/A3. In the event that any of the counterparties to the oil hedge contracts default on their obligations to make payments under such contracts, the cash distributions to the trust unitholders would likely be materially reduced as the hedge payments are intended to provide additional cash to the trust during periods of lower oil prices. SandRidge will not be required to make payments to the trust under the derivatives agreement to the extent of payment defaults by SandRidge's hedge contract counterparties. Following this offering, except in limited circumstances involving the restructuring of an existing hedge, the trust will have no ability to terminate its hedge contracts or enter into additional hedges of its own. See "—SandRidge's ability to satisfy its obligations to the trust depends on its financial position, and in the event of a default by SandRidge in its obligation to drill the Development Wells, or in the event of SandRidge's bankruptcy, it may be expensive and time-consuming for the trust to exercise its remedies."

         For Development Wells drilled on properties where SandRidge is not the operator, SandRidge will rely on third party operators to drill the Development Wells, and for Development Wells where SandRidge is the operator, SandRidge may rely on third party servicers to conduct the drilling operations.

        SandRidge expects to operate approximately 67% of the Development Wells during the subordination period. For Development Wells drilled on properties where SandRidge is not the operator, however, SandRidge will rely on third party operators to drill the Development Wells. In addition, where SandRidge is the operator of a Development Well, it may rely on third party service providers to perform the necessary drilling operations. The ability of third-party operators to help SandRidge meet the drilling

28


Table of Contents

obligation, and the ability of third-party servicers to perform drilling operations for SandRidge, will depend on those operators' future financial condition and economic performance and access to capital, which, in turn, will depend upon the supply and demand for oil and natural gas, prevailing economic conditions and financial, business and other factors. The failure of a third-party operator to adequately perform operations could delay drilling or completion of wells, or reduce production from the Underlying Properties and the cash available for distribution to trust unitholders. SandRidge may be provided little or no notice by these operators that they are failing to drill the Development Wells in accordance with pre-existing schedules. If the Development Wells take longer to be drilled and completed than currently anticipated, this may delay revenue attributable to the production of oil and natural gas by such wells. The revenues distributable to the trust and the amount of cash distributable to the trust unitholders would similarly be delayed.

        Because SandRidge does not have a majority working interest in the non-operated properties comprising the Underlying Properties, SandRidge may not be able to remove the operator in the event of poor or untimely performance. If the Development Wells take longer to be drilled than currently anticipated, this may delay revenue attributable to the production of oil and natural gas by such wells. The revenues distributable to the trust and the amount of cash distributable to the trust unitholders would similarly be delayed.

         Production of oil and natural gas on the Underlying Properties could be materially and adversely affected by severe or unseasonable weather.

        Production of oil and natural gas on the Underlying Properties could be materially and adversely affected by severe weather. Repercussions of severe weather conditions may include:

         The initial public offering price of the common units may not be indicative of future ending prices, there has been no public market for the common units, and no independent appraisal of the value of the royalty interests has been performed.

        The initial public offering price of the common units will be determined by negotiation among SandRidge, the trust and the underwriters. Among the factors to be considered in determining the initial public offering price, in addition to prevailing market conditions, will be current and historical oil and natural gas prices, current and prospective conditions in the supply and demand for oil and natural gas, reserve and production quantities estimated for the royalty interests and the trust's cash distributions prospects. None of SandRidge, the trust or the underwriters will obtain any independent appraisal or other opinion of the value of the royalty interests other than the reserve report prepared by Netherland Sewell.

         The trust is managed by a trustee who cannot be replaced except at a special meeting of trust unitholders.

        The business and affairs of the trust will be managed by the trustee. Your voting rights as a trust unitholder are more limited than those of stockholders of most public corporations. For example, there is no requirement for annual meetings of trust unitholders or for an annual or other periodic re-election of the trustee. The trust agreement provides that the trustee may only be removed and replaced by the holders of a majority of the outstanding trust units, excluding trust units held by SandRidge, voting in person or by proxy at a special meeting of trust unitholders at which a quorum is present called by either the trustee or the holders of not less than 10% of the outstanding trust units. As a result, it may be difficult

29


Table of Contents

for public unitholders to remove or replace the trustee without the cooperation of holders of a substantial percentage of the outstanding trust units.

         Trust unitholders have limited ability to enforce provisions of the royalty interests, and SandRidge's liability to the trust is limited.

        If the trustee does not take appropriate action to enforce provisions of the conveyances creating the royalty interests a trust unitholder's recourse would be limited to bringing a lawsuit against the trustee to compel the trustee to take specified actions. The trust agreement expressly limits a trust unitholder's ability to directly sue SandRidge or any other party other than the trustee. As a result, trust unitholders will not be able to sue SandRidge or any future owner of the Underlying Properties to enforce the trust's rights under the conveyances. Furthermore, the royalty interest conveyances provide that, except as set forth in the conveyances, SandRidge will not be liable to the trust for the manner in which it performs its duties in operating the Underlying Properties as long as it acts in good faith and, to the fullest extent permitted by law, will owe no fiduciary duties to the trust or the unitholders.

         Courts outside of Delaware may not recognize the limited liability of the trust unitholders provided under Delaware law.

        Under the Delaware Statutory Trust Act, trust unitholders will be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit under the General Corporation Law of the State of Delaware. However, courts in jurisdictions outside of Delaware may not give effect to such limitation.

         Sales of trust units by SandRidge could have an adverse impact on the trading price of the common units.

        After the closing of the offering, SandRidge will hold an aggregate of 11,187,500 common units and 12,062,500 subordinated units. All of the subordinated units will automatically convert into common units on a one-for-one basis at the end of the subordination period. SandRidge has agreed not to sell any trust units for a period of 180 days after the date of this prospectus without the consent of Morgan Stanley & Co. LLC and Raymond James & Associates, Inc., acting as representatives of the several underwriters. See "Trust Units Eligible for Future Sale—SandRidge Lock-up Agreement." After such period, SandRidge may sell trust units in the public or private markets, and any such sales could have an adverse impact on the price of the common units or on any trading market that may develop. The trust has granted registration rights to SandRidge, which, if exercised, would facilitate sales of common units by SandRidge to the public. See "Trust Units Eligible for Future Sale—Registration Rights Agreement."

         SandRidge could have interests that conflict with the interests of the trust and trust unitholders.

        As a working interest owner in the Underlying Properties, SandRidge could have interests that conflict with the interests of the trust and the trust unitholders. For example:

        In addition, SandRidge has agreed that, if at any time the trust's cash on hand (including available cash reserves) is not sufficient to pay the trust's ordinary course administrative expenses as they become due, SandRidge will loan funds to the trust necessary to pay such expenses. Any such loan will be on an unsecured basis, and the terms of such loan will be substantially the same as those which would be obtained in an arms' length transaction between SandRidge and an unaffiliated third party. If SandRidge provides such funds to the trust, it would become a creditor of the trust and its interests as a creditor could conflict with the interests of unitholders. Finally, as hedge manager to the trust, SandRidge will have the ability to negotiate the terms of any novation or transfer of any hedge contract to which it is a party to the trust.

         SandRidge may sell all or a portion of the Underlying Properties, subject to and burdened by the royalty interests, after satisfying its drilling obligation to the trust; any such purchaser could have a weaker financial position and/or be less experienced in oil and natural gas development and production than SandRidge.

        You will not be entitled to vote on any sale of the Underlying Properties if the Underlying Properties are sold subject to and burdened by the royalty interests and the trust will not receive any proceeds from any such sale. The purchaser would be responsible for all of SandRidge's obligations relating to the royalty interests on the portion of the Underlying Properties sold, and SandRidge would have no continuing obligation to the trust for those properties. Additionally, SandRidge may enter into farmout or joint venture arrangements with respect to the wells burdened by the trust's royalty interest. Any purchaser, farmout counterparty or joint venture partner could have a weaker financial position and/or be less experienced in oil and natural gas development and production than SandRidge.

         SandRidge's ability to satisfy its obligations to the trust depends on its financial position, and in the event of a default by SandRidge in its obligation to drill the Development Wells, or in the event of SandRidge's bankruptcy, it may be expensive and time-consuming for the trust to exercise its remedies.

        Pursuant to the terms of the development agreement, SandRidge will be obligated to drill, or cause to be drilled, the Development Wells at its own expense. SandRidge operates 79% of the Producing Wells and expects to operate approximately 67% of the Development Wells during the subordination period. The conveyances provide that SandRidge will be obligated to market, or cause to be marketed, the oil and natural gas production related to the Underlying Properties. Additionally, SandRidge will be the counterparty to the trust's derivatives agreement and will have certain obligations to the trust under the agreement. In the event that SandRidge defaults on its obligation to make payments under the derivatives agreement, the cash distributions to the trust unitholders may be materially reduced as these payments are intended to provide additional cash to the trust during periods of lower oil and natural gas prices. Due to the trust's reliance on SandRidge to fulfill these numerous obligations, the value of the trust's royalty interest and its ultimate cash available for distribution will be highly dependent on SandRidge's performance.

        SandRidge has drilling obligations to two other royalty trusts, which will require it to make capital expenditures over the next several years at the same time it plans to drill the Development Wells. SandRidge's ability to satisfy its drilling obligation to the trust will depend on, among other things, the availability of sufficient funds and drilling rigs. More generally, SandRidge's ability to satisfy its drilling obligation to the trust and to perform its other obligations to the trust will depend on its future financial condition and economic performance and access to capital, which in turn will depend upon the supply and demand for oil and natural gas, prevailing economic conditions and financial, business and other factors, many of which are beyond SandRidge's control. See "SandRidge Energy, Inc." and "Where You Can Find More Information" for additional information relating to SandRidge.

        In the event that SandRidge defaults on its obligation to drill the Development Wells, the trust would be able to foreclose on the Drilling Support Lien to the extent of SandRidge's remaining interests in the undeveloped portions of the AMI, attempt to collect money damages from SandRidge and pursue other available legal remedies against SandRidge. However, the trust is not permitted to obtain specific performance from SandRidge of its drilling obligation, and the maximum amount the trust can recover in a foreclosure or other action is limited to approximately $269.1 million, which amount will be reduced proportionately, once SandRidge has completed 103 Development Wells, as each of the remaining Development Well is drilled. The value of SandRidge's interests in the undeveloped portions of the AMI secured by the Drilling Support Lien may not be equal to the amount recoverable at any given time, and such interests may be worth considerably less. The process of foreclosing on such collateral may be expensive and time-consuming and delay the drilling and completion of the Development Wells; such delays and expenses would reduce trust distributions by reducing the amount of proceeds available for distribution. Any amounts actually recovered in a foreclosure action would be applied to completion of SandRidge's drilling obligation, would not result in any distribution to the trust unitholders and may be insufficient to drill the number of wells needed for the trust to realize the full value of the Development Royalty Interest. Furthermore, the trust would have to seek a new party to perform the drilling and operations of the wells. The trust may not be able to find a replacement driller or operator, and it may not be able to enter into a new agreement with such replacement party on favorable terms within a reasonable period of time. As long as the trust's royalty interests are pledged as collateral to the trust's hedge counterparties, the trust's arranging for a replacement driller or operator may be more difficult or impossible. In such an event, the production from the trust's properties and the trust's revenues would decline. If a decline in the trust's revenues prevents it from satisfying its obligations under its hedging arrangements, the hedging counterparties could foreclose on the trust's royalty interests. The possibility of this foreclosure could deter the trust from exercising its right to foreclose on the Drilling Support Lien.

        SandRidge will not be required to maintain a segregated account for proceeds payable to the trust. The proceeds of the royalty interests may be commingled with proceeds of SandRidge's retained interest in the Underlying Properties for the period of time between SandRidge's sale of production attributable to the trust's royalty interests and the quarterly payment to the trust of its share of proceeds. It is possible that the trust may not have adequate facts to trace its entitlement to funds in the commingled pool of funds and that other persons may, in asserting claims against SandRidge's retained interest, be able to assert claims to the proceeds that should be delivered to the trust. If there is an event of default under SandRidge's credit facility, SandRidge must keep its accounts with banks that enter into control agreements with the administrative agent under the credit facility, which would permit the administrative agent to direct payment of funds in such accounts during the pendency of an event of default. In addition, during any bankruptcy of SandRidge, it is possible that payments of the royalties may be delayed or deferred. During the pendency of any SandRidge bankruptcy proceedings, the trust's ability to foreclose on the Drilling Support Lien, and the ability to collect cash payments being held in SandRidge's accounts that are attributable to production from the trust properties, may be stayed by the bankruptcy court. Delay in realizing on the collateral for the Drilling Support Lien is possible, and it cannot be guaranteed that a bankruptcy court would permit such foreclosure. It is possible that the bankruptcy would also delay the execution of a new agreement with another driller or operator. If the trust enters into a new agreement with a drilling or operating partner, the new partner might not achieve the same levels of production or sell oil and natural gas at the same prices as SandRidge was able to achieve.

         Oil and natural gas wells are subject to operational hazards that can cause substantial losses. SandRidge maintains insurance; however, SandRidge may not be adequately insured for all such hazards.

        There are a variety of operating risks inherent in oil and natural gas production and associated activities, such as fires, leaks, explosions, mechanical problems, major equipment failures, blowouts, uncontrollable flow of oil, natural gas, water or drilling fluids, casing collapses, abnormally pressurized formations and natural disasters. The occurrence of any of these or similar accidents that temporarily or permanently halt the production and sale of oil and natural gas at any of the Underlying Properties will reduce trust distributions by reducing the amount of proceeds available for distribution.

        Additionally, if any of such risks or similar accidents occur, SandRidge could incur substantial losses as a result of injury or loss of life, severe damage or destruction of property, natural resources and equipment, regulatory investigation and penalties and environmental damage and clean-up responsibility. If SandRidge experiences any of these problems, its ability to conduct operations and perform its obligations to the trust could be adversely affected. While SandRidge intends to obtain and maintain insurance coverage it deems appropriate for these risks with respect to the Underlying Properties, SandRidge's operations may result in liabilities exceeding such insurance coverage or liabilities not covered by insurance. If a well is damaged, SandRidge would have no obligation to drill a replacement well or make the trust whole for the loss.

        For more information on SandRidge's insurance coverage, please see "The Underlying Properties—Insurance."

         SandRidge is subject to complex federal, state, local and other laws and regulations that could adversely affect the cost, manner or feasibility of conducting its operations or expose SandRidge to significant liabilities.

        SandRidge's oil and natural gas exploration, production, transportation and treatment operations are subject to complex and stringent laws and regulations. In order to conduct its operations in compliance with these laws and regulations, SandRidge must obtain and maintain numerous permits, approvals and certificates from various federal, state and local governmental authorities. SandRidge may incur substantial costs in order to maintain compliance with these existing laws and regulations. Further, in light of the explosion and fire on the drilling rig Deepwater Horizon in the Gulf of Mexico, as well as recent incidents involving the release of oil and natural gas and fluids as a result of drilling activities in the United

33


Table of Contents

States, there has been a variety of regulatory initiatives at the federal and state levels to restrict oil and natural gas drilling operations in certain locations. Any increased regulation or suspension of oil and natural gas exploration and production, or revision or reinterpretation of existing laws and regulations, that arises out of these incidents or otherwise could result in delays and higher operating costs. Such costs or significant delays could have a material adverse effect on SandRidge's business, financial condition and results of operations. SandRidge must also comply with laws and regulations prohibiting fraud and market manipulations in energy markets. To the extent SandRidge is a shipper on interstate pipelines, it must comply with the tariffs of such pipelines and with federal policies related to the use of interstate capacity.

        Laws and regulations governing oil and natural gas exploration and production may also affect production levels. SandRidge is required to comply with federal and state laws and regulations governing conservation matters, including provisions related to the unitization or pooling of the oil and natural gas properties; the establishment of maximum rates of production from wells; the spacing of wells; and the plugging and abandonment of wells. These and other laws and regulations can limit the amount of oil and natural gas SandRidge can produce from its wells, limit the number of wells it can drill, or limit the locations at which it can conduct drilling operations, which in turn could negatively impact trust distributions, estimated and actual future net revenues to the trust and estimates of reserves attributable to the trust's interests.

        New laws or regulations, or changes to existing laws or regulations may unfavorably impact SandRidge, could result in increased operating costs and have a material adverse effect on SandRidge's financial condition and results of operations. For example, Congress has recently considered, and may continue to consider, legislation that, if adopted in its proposed form, would subject companies involved in oil and natural gas exploration and production activities to, among other items, additional regulation of and restrictions on hydraulic fracturing of wells, and the elimination of most U.S. federal tax incentives and deductions available to oil and natural gas exploration and production activities. In addition, the Dodd-Frank Wall Street Reform and Consumer Protection Act and rules promulgated thereunder could reduce trading positions in the energy futures markets and materially reduce hedging opportunities for SandRidge, which could adversely affect its revenues and cash flows during periods of low commodity prices, and which could adversely affect the ability to restructure the trust's hedges when it might be desirable to do so.

        Additionally, state and federal regulatory authorities may expand or alter applicable pipeline safety laws and regulations, compliance with which may require increased capital costs on the part of SandRidge and third party downstream oil and natural gas transporters. These and other potential regulations could increase SandRidge's operating costs, reduce SandRidge's liquidity, delay SandRidge's operations, increase direct and third party post production costs associated with the trust's interests or otherwise alter the way SandRidge conducts its business, which could have a material adverse effect on SandRidge's financial condition, results of operations and cash flows and which could reduce cash received by or available for distribution, including any amounts paid by SandRidge for transportation on downstream interstate pipelines.

         The operations of SandRidge are subject to environmental laws and regulations that could adversely affect the cost, manner or feasibility of conducting operations or result in significant costs and liabilities.

        The oil and natural gas exploration and production operations of SandRidge in the Mississippian formation are subject to stringent and comprehensive federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. These laws and regulations may impose numerous obligations that are applicable to SandRidge's operations including the acquisition of a permit before conducting drilling; water withdrawal or waste disposal activities; the restriction of types, quantities and concentration of materials that can be released into the environment; the limitation or prohibition of drilling activities on certain lands lying within wilderness, wetlands and other protected areas; and the imposition of substantial liabilities for

34


Table of Contents

pollution resulting from operations. Numerous governmental authorities, such as the U.S. Environmental Protection Agency ("EPA") and analogous state agencies, have the power to enforce compliance with these laws and regulations and the permits issued under them, often requiring difficult and costly actions. Failure to comply with these laws and regulations may result in the assessment of administrative, civil or criminal penalties; the imposition of investigatory or remedial obligations; and the issuance of injunctions limiting or preventing some or all of SandRidge's operations.

        There is inherent risk of incurring significant environmental costs and liabilities in the performance of SandRidge's operations due to its handling of petroleum hydrocarbons and wastes, because of air emissions and wastewater discharges related to its operations, and as a result of historical industry operations and waste disposal practices. Under certain environmental laws and regulations, SandRidge could be subject to joint and several strict liability for the removal or remediation of previously released materials or property contamination regardless of whether SandRidge was responsible for the release or contamination or if the operations were in compliance with all applicable laws at the time those actions were taken. Private parties, including the owners of properties upon which SandRidge's wells are drilled and facilities where SandRidge's petroleum hydrocarbons or wastes are taken for reclamation or disposal may also have the right to pursue legal actions to enforce compliance, as well as to seek damages for contamination even in the absence of non-compliance, with environmental laws and regulations or for personal injury or property damage. In addition, the risk of accidental spills or releases could expose SandRidge to significant liabilities that could have a material adverse effect on its financial condition or results of operations. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly construction, drilling, water management, completion, waste handling, storage, transport, disposal or cleanup requirements could require SandRidge to make significant expenditures to attain and maintain compliance and may otherwise have a material adverse effect on its results of operations, competitive position or financial condition. SandRidge may not be able to recover some or any of these costs from insurance. As a result of the increased cost of compliance, SandRidge may decide to discontinue drilling. Additionally, permitting delays may inhibit SandRidge's ability to drill the Development Wells on schedule.

        For more information on the environmental laws and regulations governing SandRidge's operations, please see "The Underlying Properties—Regulation."

         Climate change laws and regulations restricting emissions of "greenhouse gases" could result in increased operating costs and reduced demand for the oil and natural gas that SandRidge produces while the physical effects of climate change could disrupt SandRidge's production and cause SandRidge to incur significant costs in preparing for or responding to those effects.

        In December 2009, the EPA published its findings that emissions of carbon dioxide, methane and other greenhouse gases ("GHGs") present a danger to public health and the environment. These findings allow the agency to adopt and implement regulations that restrict emissions of GHGs under existing provisions of the federal Clean Air Act. Accordingly, the EPA has adopted regulations that require a reduction in emissions of GHGs from motor vehicles and also trigger Clean Air Act construction and operating permit review for GHG emissions from certain large stationary sources. The EPA's rules relating to emissions of GHGs from large stationary sources of emissions are currently subject to a number of political and legal challenges, but the federal courts have thus far declined to issue any injunctions to prevent EPA from implementing, or requiring state environmental agencies to implement, the rules. In addition, in October 2009, the EPA published a final rule requiring the reporting of GHG emissions from specified large GHG emission sources in the United States, beginning in 2011 for emissions occurring in 2010. In November 2010, the EPA published a final rule that expands its October 2009 final rule on reporting of GHG emissions to require certain owners and operators of onshore oil and natural gas production to monitor greenhouse gas emissions beginning in 2011 and to report those emissions beginning in 2012. Both houses of Congress have from time to time considered legislation to reduce emissions of GHGs and almost one-half of the states, either individually or through multi-state regional

35


Table of Contents

initiatives, already have begun implementing legal measures to reduce emissions of GHGs. The adoption and implementation of any regulations imposing reporting obligations on, or limiting emissions of GHGs from, SandRidge's equipment and operations could require SandRidge to incur additional costs to reduce emissions of GHGs associated with its operations or could adversely affect demand for the oil and natural gas that it produces. Finally, some scientists have concluded that increasing concentrations of greenhouse gases in the Earth's atmosphere may produce climate change that could have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climatic events; if any such effects were to occur, they could have an adverse effect on SandRidge's assets and operations.

         Federal and state legislative and regulatory initiatives as well as governmental reviews relating to hydraulic fracturing could result in increased costs and additional operating restrictions or delays as well as adversely affect SandRidge's level of production.

        SandRidge makes extensive use of hydraulic fracturing in producing from the Underlying Properties. The process involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate production. The process is typically regulated by state oil and gas commissions. However, the EPA recently asserted federal regulatory authority over certain hydraulic fracturing practices not currently employed by SandRidge in the AMI. Also, legislation has been introduced, but not enacted, in Congress to provide for federal regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. In addition, some states have adopted, and other states, including Kansas, are considering adopting, regulations that could restrict hydraulic fracturing in certain circumstances. If new laws or regulations that significantly restrict or regulate hydraulic fracturing are adopted, such legal requirements could cause project delays and make it more difficult or costly for SandRidge to perform fracturing to stimulate production from the Mississippian formation. These delays or additional costs could adversely affect the determination of whether a well is commercially viable. Restrictions on hydraulic fracturing could also reduce the amount of oil and natural gas that SandRidge is ultimately able to produce in commercial quantities from the Underlying Properties.

        In addition, a number of federal agencies are analyzing, or have been requested to review, a variety of environmental issues associated with hydraulic fracturing. The White House Council on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices, and a committee of the United States House of Representatives has conducted an investigation of hydraulic fracturing practices. The EPA has commenced a study of the potential environmental effects of hydraulic fracturing on drinking water and groundwater, with initial results expected to be available by late 2012 and final results by 2014. Moreover, the EPA announced on October 20, 2011 that it is also launching a study regarding wastewater resulting from hydraulic fracturing activities and currently plans to propose standards by 2014 that such wastewater must meet before being transported to a treatment plant. In addition, the U.S. Department of Energy is conducting an investigation of practices the agency could recommend to better protect the environment from drilling using hydraulic fracturing completion methods. Also, the U.S. Department of the Interior is considering disclosure requirements or other mandates for hydraulic fracturing on federal lands. Additionally, certain members of Congress have called upon the U.S. Government Accountability Office to investigate how hydraulic fracturing might adversely affect water resources; the U.S. Securities & Exchange Commission to investigate the natural gas industry and any possible misleading of investors or the public regarding the economic feasibility of pursuing natural gas deposits in shales by means of hydraulic fracturing; and the U.S. Energy Information Administration to provide a better understanding of that agency's estimates regarding natural gas reserves, including reserves from shale formations, as well as uncertainties associated with those estimates. These ongoing or proposed studies, depending on their degree of pursuit and any meaningful results obtained, could spur initiatives to further regulate hydraulic fracturing under the federal Safe Drinking Water Act or other regulatory mechanisms.

         The trust will be subject to the requirements of the Sarbanes-Oxley Act of 2002, which may impose cost and operating challenges on it.

        The trust will be subject to certain of the requirements of the Sarbanes-Oxley Act of 2002, which will require, among other things, maintenance by the trust of, and reports regarding the effectiveness of, a system of internal control over financial reporting. Complying with these requirements may pose operational challenges and may cause the trust to incur unanticipated expenses. Any failure by the trust to comply with these requirements could lead to a loss of public confidence in the trust's internal controls and in the accuracy of the trust's publicly reported results.

Tax Risks Related to the Units

         The trust's tax treatment depends on its status as a partnership for U.S. federal income tax purposes. If the U.S. Internal Revenue Service ("IRS") were to treat the trust as a corporation for U.S. federal income tax purposes, then its cash available for distribution to unitholders would be substantially reduced.

        The anticipated after-tax economic benefit of an investment in the trust units depends largely on the trust being treated as a partnership for U.S. federal income tax purposes. The trust has not requested, and does not plan to request, a ruling from the Internal Revenue Service, or IRS, on this or any other tax matter affecting it.

        It is possible in certain circumstances for a publicly traded trust otherwise treated as a partnership, such as the trust, to be treated as a corporation for U.S. federal income tax purposes. In addition, a change in current law could cause the trust to be treated as a corporation for U.S. federal income tax purposes or otherwise subject it to taxation as an entity.

        If the trust were treated as a corporation for U.S. federal income tax purposes, it would pay federal income tax on its taxable income at the corporate tax rate, which is currently a maximum of 35%. Distributions to you would generally be taxed again as corporate distributions, and no income, gains, losses, deductions or credits would flow through to you without first being subjected to taxation at the entity level. Because a tax would be imposed upon the trust as a corporation, its cash available for distribution to you would be substantially reduced. Therefore, treatment of the trust as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to the trust unitholders, likely causing a substantial reduction in the value of the trust units.

         If the trust were subjected to a material amount of additional entity-level taxation by individual states, it would reduce the trust's cash available for distribution to unitholders.

        Changes in current state law may subject the trust to additional entity-level taxation by individual states. Because of widespread state budget deficits and other reasons, several states are evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise and other forms of taxation. Imposition of such taxes may substantially reduce the cash available for distribution to unitholders and, therefore, negatively impact the value of an investment in trust units. The trust agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects the trust to additional amounts of entity-level taxation for state or local income tax purposes, the subordination threshold amounts, incentive threshold amounts and target distribution amounts may be adjusted to reflect the impact of that law on the trust.

         The tax treatment of an investment in trust units could be affected by recent and potential legislative changes, possibly on a retroactive basis.

        The Health Care and Education Reconciliation Act of 2010 includes a provision that, in taxable years beginning after December 31, 2012, subjects an individual having adjusted gross income in excess of $200,000 (or $250,000 for married taxpayers filing joint returns) to an additional "Medicare tax" equal generally to 3.8% of the lesser of such excess or the individual's net investment income, which appears to

37


Table of Contents

include interest income and royalty income derived from investments such as the trust units as well as any net gain from the disposition of trust units. In addition, absent new legislation extending the current rates, beginning January 1, 2013, the highest marginal U.S. federal income tax rate applicable to ordinary income and long-term capital gains of individuals will increase to 39.6% and 20%, respectively. Moreover, these rates are subject to change by new legislation at any time.

        Current law may change so as to cause the trust to be treated as a corporation for U.S. federal income tax purposes or otherwise subject the trust to entity-level taxation. Specifically, the present U.S. federal income tax treatment of publicly traded partnerships, including the trust, or an investment in the trust units may be modified by administrative, legislative or judicial interpretation at any time. For example, at the federal level, legislation has been proposed in the past that would have eliminated partnership tax treatment for certain publicly traded partnerships. Although such legislation would not have applied to the trust as it was proposed, it could be reintroduced in a manner that does apply to the trust.

        The trust agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects the trust to taxation as a corporation or otherwise subjects it to entity-level taxation for U.S. federal income tax purposes, the subordination threshold amounts, incentive threshold amounts and target distribution amounts may be adjusted to reflect the impact of that law on the trust.

         The trust will adopt positions that may not conform to all aspects of existing Treasury Regulations. If the IRS contests the tax positions the trust takes, the value of the trust units may be adversely affected, the cost of any IRS contest will reduce the trust's cash available for distribution and income, gain, loss and deduction may be reallocated among trust unitholders.

        If the IRS contests any of the U.S. federal income tax positions the trust takes, the value of the trust units may be adversely affected because the cost of any IRS contest will reduce the trust's cash available for distribution and income, gain, loss and deduction may be reallocated among trust unitholders. For example, the trust will generally prorate its items of income, gain, loss and deduction between transferors and transferees of the trust units each quarter based upon the record ownership of the trust units on the quarterly record date in such quarter instead of on the basis of the date a particular trust unit is transferred. Although simplifying conventions are contemplated by the Internal Revenue Code, and most publicly traded partnerships use similar simplifying conventions, the use of these methods may not be permitted under existing Treasury Regulations.

        The trust has not requested a ruling from the IRS with respect to its treatment as a partnership for U.S. federal income tax purposes or any other matter affecting the trust. The IRS may adopt positions that differ from the conclusions of the trust's counsel expressed in this prospectus or from the positions the trust takes. It may be necessary to resort to administrative or court proceedings to attempt to sustain some or all of the conclusions of the trust's counsel or the positions the trust takes. A court may not agree with some or all of the conclusions of the trust's counsel or positions the trust takes. Any contest with the IRS may materially and adversely impact the market for the trust units and the price at which they trade. In addition, the trust's costs of any contest with the IRS will be borne indirectly by the trust unitholders because the costs will reduce the trust's cash available for distribution.

         You will be required to pay taxes on your share of the trust's income even if you do not receive any cash distributions from the trust.

        Because the trust unitholders will be treated as partners to whom the trust will allocate taxable income that could be different in amount than the cash the trust distributes, you will be required to pay any federal income taxes and, in some cases, state and local income taxes on your share of the trust's taxable income even if you receive no cash distributions from the trust. You may not receive cash distributions from the trust equal to your share of the trust's taxable income or even equal to the actual tax liability that results from that income.

         Tax gain or loss on the disposition of the trust units could be more or less than expected.

        If you sell your trust units, you will recognize a gain or loss equal to the difference between the amount realized and your tax basis in those trust units. Because distributions in excess of your allocable share of the trust's net taxable income decrease your tax basis in your trust units, the amount, if any, of such prior excess distributions with respect to the trust units you sell will, in effect, become taxable income to you if you sell such trust units at a price greater than your tax basis in those trust units, even if the price you receive is less than your original cost. Furthermore, a substantial portion of the amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including depletion recapture. Please read "U.S. Federal Income Tax Considerations—Disposition of Trust Units—Recognition of Gain or Loss" for a further discussion of the foregoing.

         The ownership and disposition of trust units by non-U.S. persons may result in adverse tax consequences to them.

        Investment in trust units by non-U.S. persons raises issues unique to them. For example, distributions to non-U.S. persons will be reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons may be required to file U.S. federal income tax returns and pay tax on their share of the trust's taxable income or proceeds from the sale of trust units. If you are a non-U.S. person, you should consult a tax advisor before investing in the trust units.

         The trust will treat each purchaser of trust units as having the same economic attributes without regard to the actual trust units purchased. The IRS may challenge this treatment, which could adversely affect the value of the trust units.

        Due to a number of factors, including the trust's inability to match transferors and transferees of trust units, the trust will adopt positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely alter the tax effects of an investment in trust units. It also could affect the timing of tax benefits or the amount of gain from your sale of trust units and could have a negative impact on the value of the trust units or result in audit adjustments to your tax returns. Please read "U.S. Federal Income Tax Considerations—Tax Consequences of Trust Unit Ownership—Section 754 Election."

         The trust will prorate its items of income, gain, loss and deduction between transferors and transferees of the trust units each quarter based upon the record ownership of the trust units on the quarterly record date in such quarter instead of on the basis of the date a particular trust unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among the affected trust unitholders.

        The trust will generally prorate its items of income, gain, loss and deduction between transferors and transferees of the trust units based upon the record ownership of the trust units on the quarterly record date in such quarter instead of on the basis of the date a particular trust unit is transferred. The use of this proration method may not be permitted under existing Treasury Regulations, and, accordingly, the trust's counsel is unable to opine as to the validity of this method. If the IRS were to challenge the trust's proration method, the trust may be required to change its allocation of items of income, gain, loss and deduction among the trust unitholders and the costs to the trust of implementing and reporting under any such changed method may be significant. Please read "U.S. Federal Income Tax Considerations—Disposition of Trust Units—Allocations Between Transferors and Transferees."

         The trust will adopt certain valuation methodologies that may affect the income, gain, loss and deduction allocable to the trust unitholders. The IRS may challenge this treatment, which could adversely affect the value of the trust units.

        The U.S. federal income tax consequences of the ownership and disposition of trust units will depend in part on the trust's estimates of the relative fair market values, and the initial tax bases, of the trust's assets. Although the trust may from time to time consult with professional appraisers regarding valuation matters, the trust will make many of the relative fair market value estimates itself. These estimates and determinations of basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss or deductions previously reported by trust unitholders might change, and trust unitholders might be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.

         The sale or exchange of 50% or more of the trust's capital and profits interests during any twelve-month period will result in the termination of the trust for U.S. federal income tax purposes.

        The trust will be considered to have technically terminated for U.S. federal income tax purposes if there is a sale or exchange of 50% or more of the total interests in its capital and profits within a twelve-month period. For purposes of determining whether the 50% threshold has been met, multiple sales of the same trust unit within any 12 month period will be counted only once. The trust's termination would, among other things, result in the closing of its taxable year for all trust unitholders, which would result in the trust filing two tax returns (and the trust unitholders could receive two Schedules K-1) for one calendar year. The IRS has recently announced a relief procedure whereby if a publicly traded partnership that has technically terminated requests and the IRS grants special relief, among other things, the partnership will be required to provide only a single Schedule K-1 to unitholders for the tax year in which the termination occurs. In the case of a unitholder reporting on a taxable year other than a calendar year ending December 31, the closing of the trust's taxable year as a result of any technical termination may also result in more than 12 months of the trust's taxable income being includable in his taxable income for the year of termination. A technical termination would not affect the trust's classification as a partnership for U.S. federal income tax purposes, but instead, the trust would be treated as a new partnership for tax purposes. If treated as a new partnership, the trust must make new tax elections and could be subject to penalties if the trust is unable to determine that a technical termination occurred.

         Certain U.S. federal income tax preferences currently available with respect to oil and natural gas production may be eliminated as a result of future legislation.

        In recent years, the Obama administration's budget proposals and other proposed legislation have included elimination of certain key U.S. federal income tax incentives currently available to oil and gas exploration and production. If enacted into law, these provisions would eliminate certain tax preferences applicable to taxpayers engaged in the exploration or production of natural resources. Specifically, these proposals have included repeal of the deduction for percentage depletion with respect to wells, including perpetual royalty interests in such wells, in which case only cost depletion would be available. It is unclear whether any such changes will be enacted and, if so, when any such changes would become effective.

USE OF PROCEEDS

        The trust is offering all of the common units to be sold in this offering. Assuming no exercise of the underwriters' over-allotment option and an initial public offering price of $            per common unit, the estimated net proceeds of this offering will be approximately $             million, after deducting underwriting discounts and commissions and offering expenses. The trust will deliver all of the net proceeds to one or more of SandRidge's wholly-owned subsidiaries as part of the consideration for the conveyance of the royalty interests. See "The Trust—Formation Transactions."

        At the initial closing, 3,750,000 common units will be issued and retained by the trust and will be used to satisfy (if necessary) the over-allotment option granted to the underwriters. If the over-allotment option is exercised, the trust will sell to the underwriters such number of the retained units as is necessary to satisfy the over-allotment option, and will then deliver the net proceeds of such sale, together with any remaining unsold units, to one or more SandRidge subsidiaries as partial consideration for the conveyance of certain of the royalty interests. If the over-allotment option is not exercised by the underwriters, the retained units will be delivered to SandRidge subsidiaries, as partial consideration for the conveyance of certain of the royalty interests, promptly following the 30th day after the initial closing.

        SandRidge intends to use the proceeds received from the offering for general corporate purposes, which may include the funding of the drilling obligation, which is estimated to be approximately $384.4 million.

SandRidge's Experience With Other Royalty Trusts

        SandRidge is the sponsor of two other royalty trusts, SandRidge Mississippian Trust I and SandRidge Permian Trust. These trusts have many of the same terms as SandRidge Mississippian Trust II. Summary information about each of these two trust follows.

        SandRidge Mississippian Trust I (NYSE: SDT).    In connection with the formation of SandRidge Mississippian Trust I and its initial public offering, SandRidge conveyed royalty interests in specified oil and natural gas properties in the Mississippian formation in Alfalfa, Garfield, Grant, Major and Woods Counties in Oklahoma to SandRidge Mississippian Trust I in exchange for trust units and the net proceeds of the offering. SandRidge received 3,750,000 common units and 7,000,000 subordinated units in SandRidge Mississippian Trust I, together representing an approximately 38% beneficial interest, along with approximately $338.7 million in net proceeds, before offering expenses. SandRidge Mississippian Trust I completed its initial public offering on April 12, 2011.

        SandRidge Mississippian Trust I makes quarterly cash distributions of substantially all of its cash receipts, after deducting the trust's administrative expenses, on or about 60 days following the completion of each quarter through (and including) the quarter ending December 31, 2030. On July 22, 2011, SandRidge Mississippian Trust I declared a cash distribution of approximately $1.068 per unit covering production for the period from January 1, 2011 to May 31, 2011 for record holders as of August 15, 2011. The distribution was paid on August 30, 2011. This distribution exceeded the target distribution for such period of $1.014 per unit. On October 28, 2011, SandRidge Mississippian Trust I announced a cash distribution of approximately $.816 per unit covering production for the period from June 1, 2011 through August 31, 2011. SandRidge Mississippian Trust I made this distribution on November 30, 2011 to unitholders of record as of November 15, 2011. This distribution exceeded the target distribution for such period of $.667 per unit. On February 2, 2012, SandRidge Mississippian Trust I announced a cash

43


Table of Contents

distribution of approximately $.791 per unit covering production for the period from September 1, 2011 through November 30, 2011. This distribution will be paid on or about February 29, 2012 to unitholders of record on February 14, 2012. This distribution exceeds the target distribution for such period of $.633 per unit.

        Under a development agreement with SandRidge Mississippian Trust I, SandRidge intends to drill, or cause to be drilled, a total of 123 development wells by December 31, 2014, and is obligated to complete such drilling by December 31, 2015. SandRidge's wholly owned subsidiary, SandRidge E&P, has granted to SandRidge Mississippian Trust I a lien covering its interest in the area of mutual interest in which the trust underlying properties are located in order to secure the estimated amount of the drilling costs for the interests of SandRidge Mississippian Trust I in the undeveloped underlying properties. The amount recoverable by SandRidge Mississippian Trust I pursuant to this lien may not exceed $166.1 million. As SandRidge fulfills its drilling obligation over time, the total amount that may be recovered is proportionately reduced and the completed development wells will be released from the lien. As of September 30, 2011, approximately 42 development wells had been drilled and the maximum amount recoverable under the Drilling Support Lien had been reduced to approximately $109.6 million.

        Under an administrative services agreement with SandRidge Mississippian Trust I, SandRidge receives an annual administrative services fee of $200,000 for accounting, tax preparation, bookkeeping and informational services to be performed by SandRidge on behalf of SandRidge Mississippian Trust I. SandRidge Mississippian Trust I is also party to a derivatives agreement with SandRidge that provides SandRidge Mississippian Trust I with the benefit of certain oil and natural gas derivative contracts previously entered into by SandRidge with third parties. The underlying commodity derivative contracts cover volumes of oil and natural gas production through December 31, 2015.

        SandRidge Permian Trust (NYSE: PER).    In connection with SandRidge Permian Trust's formation and initial public offering, SandRidge conveyed royalty interests in specified oil and natural gas properties in the Permian Basin in Andrews County in Texas to SandRidge Permian Trust in exchange for trust units and the net proceeds of the offering. SandRidge received 4,875,000 common units and 13,125,000 subordinated units in SandRidge Permian Trust, together representing an approximately 34% beneficial interest, along with approximately $583.7 million in net proceeds, before offering expenses. SandRidge Permian Trust completed its initial public offering on August 16, 2011.

        SandRidge Permian Trust makes quarterly cash distributions of substantially all of its cash receipts, after deducting the trust's administrative expenses, on or about 60 days following the completion of each quarter through (and including) the quarter ending March 31, 2031. On October 28, 2011, SandRidge Permian Trust announced a cash distribution of approximately $.723 per unit covering production for the period from April 1, 2011 through August 31, 2011. SandRidge Permian Trust made this distribution on November 30, 2011 to unitholders of record as of November 15, 2011. This distribution exceeded the target distribution for such period of $.660 per unit. On February 2, 2012, SandRidge Permian Trust announced a cash distribution of approximately $.554 per unit covering production for the period from September 1, 2011 through November 30, 2011. This distribution will be paid on or about February 29, 2012 to unitholders of record on February 14, 2012. This distribution exceeds the target distribution for such period of $.490 per unit.

        Under a development agreement with SandRidge Permian Trust, SandRidge intends to drill, or cause to be drilled, a total of 888 development wells by March 31, 2015, and is obligated to complete such drilling by March 31, 2016. SandRidge E&P has granted to SandRidge Permian Trust a lien covering its interest in the area of mutual interest in which the trust underlying properties are located in order to secure the estimated amount of the drilling costs for SandRidge Permian Trust's interests in the undeveloped underlying properties. The amount recoverable by SandRidge Permian Trust pursuant to this lien may not exceed approximately $295 million. As SandRidge fulfills its drilling obligation over time, the total amount that may be recovered is proportionately reduced and the completed development wells will be released

44


Table of Contents

from the lien. As of September 30, 2011, approximately 134 development wells had been drilled and the maximum amount recoverable under the lien had been reduced to approximately $250.0 million.

        Under an administrative services agreement with SandRidge Permian Trust, SandRidge receives an annual administrative services fee of $300,000 for accounting, tax preparation, bookkeeping, informational and hedge management services to be performed by SandRidge on behalf of SandRidge Permian Trust. SandRidge Permian Trust is also party to a derivatives agreement with SandRidge that provides SandRidge Permian Trust with the benefit of certain oil and derivative contracts previously entered into by SandRidge with third parties. The underlying commodity derivative contracts cover volumes of oil production through March 31, 2015.

        For a discussion of risks associated with SandRidge's ability to satisfy its obligations to the trust and its other royalty trusts, see "Risk Factors—SandRidge's ability to satisfy its obligations to the trust depends on its financial position, and in the event of a default by SandRidge in its obligations to drill the Development Wells, or in the event of a SandRidge bankruptcy, it may be expensive and time-consuming for the trust to exercise its remedies."

THE TRUST

        The trust is a statutory trust created under the Delaware Statutory Trust Act in December 2011. The business and affairs of the trust will be managed by The Bank of New York Mellon Trust Company, N.A., as trustee. In addition, The Corporation Trust Company will act as Delaware trustee of the trust. The Delaware trustee will have only minimal rights and duties as are necessary to satisfy the requirements of having a trustee in Delaware who will accept service of process on the trust under the Delaware Statutory Trust Act. Although SandRidge will operate substantially all of the Underlying Properties, SandRidge will have no ability to manage or influence the management of the trust (except through its limited voting rights as a holder of trust units and its limited ability to manage the hedging program) and, to the fullest extent permitted by law, will owe no fiduciary duties to the trust or the unitholders.

        The trustee can authorize the trust to borrow money to pay trust administrative or incidental expenses that exceed cash held by the trust. The trustee may authorize the trust to borrow from the trustee as a lender provided the terms of the loan are fair to the trust unitholders. The trustee may also deposit funds awaiting distribution in an account with itself, if the interest paid to the trust at least equals amounts paid by the trustee on similar deposits, and make other short term investments with the funds distributed to the trust. The trustee may also hold funds awaiting distribution in a non-interest bearing account.

        The trust will be responsible for paying all legal, accounting, tax advisory, engineering, printing costs and other administrative and out-of-pocket expenses incurred by or at the direction of the trustee or the Delaware trustee, including tax return and Schedule K-1 preparation and mailing costs, independent auditor fees and registrar and transfer agent fees. The trust will also be responsible for any payment obligations under the hedging arrangements and administrative expenses incurred as a result of being a publicly traded entity, including costs associated with annual and quarterly reports to unitholders. Trust administrative expenses are anticipated to aggregate approximately $1.3 million per year, although such costs could be greater or less depending on future events that cannot be predicted. Included in the annual estimate is an annual administrative fee of $150,000 for the trustee, which may be adjusted beginning on January 1, 2018 as provided in the trust agreement, an annual administrative fee of $2,400 for the Delaware trustee, an annual fee of $300,000 payable to SandRidge pursuant to the terms of the administrative services agreement and an annual fee estimated to be $15,000 payable to the collateral agent under the security instruments in respect of the lien securing the trust's obligations under its direct hedge contracts. The trustee will also receive a one-time acceptance fee of $10,000. These costs will be deducted by the trust before distributions are made to trust unitholders. The trustee intends to withhold $1.0 million from the first distribution to unitholders to establish a cash reserve available to the trustee to pay trust administrative expenses.

Formation Transactions

        At or prior to the closing of the offering, SandRidge will cause to be conveyed to the trust an 80% royalty interest in the Producing Wells and a 70% royalty interest in the Development Wells.

        The 80% royalty interest in the Producing Wells will consist of a term overriding royalty interest entitling the trust to receive 40% of the proceeds from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Producing Wells (after deducting post-production costs and any applicable taxes) for a period of 20 years commencing on January 1, 2012 (the "Term PDP Royalty") and an overriding royalty interest entitling the trust to receive 40% of the proceeds from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Producing Wells (after deducting post-production costs and any applicable taxes) (the "Perpetual PDP Royalty").

        The 70% royalty interest in the Development Wells will consist of a term overriding royalty interest entitling the trust to receive 35% of the proceeds from the sale of the production of oil and natural gas attributable to SandRidge's net revenue interest in the Development Wells (after deducting post-production costs and any applicable taxes) for a period of 20 years commencing on January 1, 2012 (the "Term Development Royalty") and an overriding royalty interest entitling the trust to receive 35% of

46


Table of Contents

the proceeds from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Development Wells (after deducting post-production costs and any applicable taxes) (the "Perpetual Development Royalty"). The Perpetual Development Royalty in respect of the Development Wells located in Kansas will have a term of 21 years commencing on January 1, 2012 and, if production commences during such period, so long thereafter as SandRidge's leasehold interests remain in force.

        The Perpetual Royalties will be conveyed directly from SandRidge E&P to the trust. The Term Royalties will be conveyed from SandRidge E&P to another wholly owned subsidiary of SandRidge ("Term Royalty Subsidiary") in exchange for a demand note in a principal amount expected to be a significant portion of the net proceeds of the offering, and then assigned from the Term Royalty Subsidiary to the trust. In exchange for the Perpetual Royalties, the trust will issue to SandRidge E&P 7,437,500 common units and 12,062,500 subordinated units. In exchange for the Term Royalties, the trust will pay a significant portion of the net proceeds of this offering to the Term Royalty Subsidiary, and the Term Royalty Subsidiary will use such proceeds to repay the demand note to SandRidge E&P. Any proceeds not paid to the Term Royalty Subsidiary will be paid to SandRidge E&P, as additional consideration for the conveyance of the Perpetual Royalties. See "Use of Proceeds."

        3,750,000 common units will be issued and retained by the trust at the initial closing, to be used to satisfy (if necessary) the over-allotment option granted to the underwriters. If the over-allotment option is exercised, the trust will sell to the underwriters such number of the retained units as is necessary to satisfy the over-allotment option, and will then deliver the net proceeds of such sale, together with any remaining unsold units, to one or more SandRidge subsidiaries as partial consideration for the conveyance of the Perpetual Royalties. If the over-allotment option is not exercised by the underwriters, the retained units will be delivered to SandRidge subsidiaries, as partial consideration for the conveyance of the Perpetual Royalties, promptly following the 30th day after the initial closing.

        The trust will sell the 25,000,000 common units offered hereby to the public, representing a 51.8% interest in the trust.

        SandRidge and the trust will enter into several agreements in connection with the conveyance of the royalty interests, including: (1) a development agreement, which sets forth SandRidge's drilling obligation to the trust with respect to the Development Wells, (2) a derivatives agreement, pursuant to which SandRidge will provide the trust with the economic effect of certain hedge contracts entered into between SandRidge and unaffiliated counterparties, (3) an administrative services agreement, which outlines SandRidge's duty to provide certain administrative services to the trust, (4) the Drilling Support Lien and (5) a registration rights agreement, which is described under "Trust Units Eligible For Resale—Registration Rights Agreement." These agreements are described in more detail below.

Termination Date; Liquidation

        The trust will dissolve and begin to liquidate on the Termination Date, which is December 31, 2031, and will soon thereafter wind up its affairs and terminate. At the Termination Date, the Term Royalties will automatically revert to SandRidge, while the Perpetual Royalties will be sold and the proceeds will be distributed to the unitholders at the Termination Date or soon thereafter, but only after the trust has paid, or made reasonable provision for payment of, all liabilities of the trust. See "Description of the Royalty Interests—Sale of the Perpetual Royalties." Any additional cash held in reserve by the trustee will also be distributed to unitholders.

Development Agreement and Drilling Support Lien

        In connection with the closing of this offering, the trust will enter into a development agreement with SandRidge and SandRidge E&P that will obligate SandRidge to drill, or cause to be drilled, all of the Development Wells. SandRidge intends to drill, or cause to be drilled, the Development Wells in the AMI by December 31, 2015 and is obligated to complete such drilling by December 31, 2016. SandRidge may, and anticipates that it will, rely on third-party operators to fulfill a portion of its drilling obligation. In

47


Table of Contents

order to secure the estimated amount of the drilling costs for the trust's interests in the Development Wells, SandRidge E&P will grant to the trust the Drilling Support Lien, covering SandRidge E&P's interests in the AMI (except the Producing Wells and any other wells that are already producing and not subject to the royalty interests). The amount obtained by the trust pursuant to the Drilling Support Lien may not exceed approximately $269.1 million. As SandRidge fulfills its drilling obligation over time, Development Wells that are completed or that are perforated (or made ready to commence stimulation) for completion and then plugged and abandoned will be released from the Drilling Support Lien. After SandRidge has drilled 103 Development Wells, the total dollar amount that may be recovered by the trust for SandRidge's failure to fulfill its drilling obligation will be proportionately reduced as SandRidge drills the remaining Development Wells.

        Calculation of a Development Well.    Under the development agreement, a Development Well is calculated based on the perforated length of the well bore (measured from the first perforation or stimulation site along the measured depth to the last perforation or stimulation site along the measured depth) and SandRidge's net revenue interest in such well. SandRidge will be credited for drilling one Development Well if the perforated length of the well bore is between 3,500 feet and 4,500 feet and SandRidge's net revenue interest in the well is equal to 47.4%.

        For wells with a perforated length of less than 3,500 feet, SandRidge will receive partial credit equal to the fraction calculated by dividing the well's perforated length by 3,500 feet. For wells with a perforated length of more than 4,500 feet, SandRidge will receive extra credit equal to the fraction calculated by dividing the well's perforated length by 4,500 feet.

        For wells in which SandRidge has a net revenue interest greater than or less than 47.4%, SandRidge will receive credit for such well in the proportion that its net revenue interest in the well bears to 47.4%.

        Accordingly, for example, if SandRidge drilled one well in which it has a 70% net revenue interest, and such well was drilled to a perforated length of 5,000 feet, such well would count for purposes of the development agreement as 1.64 Development Wells (i.e., 5,000 / 4,500 × 70% / 47.4%). If, on the other hand, SandRidge drilled one well in which it has a 40% net revenue interest, and such well was drilled to a perforated length of 3,000 feet, such well would count for purposes of the development agreement as only .72 of a Development Well (i.e., 3,000 / 3,500 × 40% / 47.4%).

        Given that SandRidge's actual net revenue interest in each Development Well may be greater than or less than 47.4% and the perforated length of each well drilled may be less than 3,500 feet or more than 4,500 feet, SandRidge may be required to drill more or less than 206 wells in order to fulfill its drilling obligation.

        SandRidge will receive credit for drilling a Development Well if the well is drilled in the AMI and perforated (or made ready to commence stimulation) horizontally for completion in the Mississippian formation, even if such well does not successfully produce hydrocarbons. Additionally, if SandRidge perforates (or makes ready to commence stimulation) a Development Well for completion and then plugs and abandons that well, it will be released from the Drilling Support Lien.

        Additional Provisions.    In drilling and completing the Development Wells, SandRidge is required to adhere to a reasonably prudent operator standard, which requires that it act with respect to the Underlying Properties as it would act with respect to its own properties, disregarding the existence of the royalty interests as burdens affecting such properties. Accordingly, SandRidge expects that the average perforated length of future well bores will be generally consistent with the perforated length of the completed Producing Wells and other Mississippian wells outside of the AMI that have been drilled and completed by SandRidge or for its account. However, due to the complexity of well completions and future developments in completion technologies, it may be appropriate in some instances to complete longer or shorter wells.

        The reserves reflected in the reserve report assume that SandRidge will drill and complete the 206 Development Wells with the same completion technique as the 67 Producing Wells completed to date.

48


Table of Contents

These 67 Producing Wells produce from perforated lengths ranging from 3,584 feet to 6,879 feet. The average perforated length contributing to production of the 67 Producing Wells and the other Mississippian wells with available perforated lengths outside of the AMI that have been completed by SandRidge is approximately 4,200 feet, which is longer than the minimum 3,500 feet perforated length upon which the definition of one full Development Well is based.

        The trust will not bear any of the costs of drilling and completing the Development Wells that SandRidge drills or causes to be drilled.

        In addition, SandRidge will covenant and agree not to drill and complete, and will not permit any other person within its control to drill and complete, any well in the AMI other than a Development Well until such time as SandRidge has met its commitment to drill the Development Wells. Once SandRidge has completed its drilling obligation, the trustee will be required to release the Drilling Support Lien in full. Upon the trustee's release of the Drilling Support Lien, SandRidge will further agree not to drill and complete, and will not permit any other person within its control to drill and complete, any well that will have a perforation (or stimulation site) that will be within 660 feet of any perforation (or stimulation site) of any Development Well or Producing Well during the time period in which any such well is producing.

Hedging Arrangements

        Hedging arrangements covering a portion of expected production will be implemented by the trust in two ways. First, SandRidge will enter into a derivatives agreement with the trust to provide the trust with the economic effect of specified hedge contracts entered into between SandRidge and unaffiliated counterparties. Under the derivatives agreement, SandRidge will pay the trust amounts it receives from its hedge counterparties, and the trust will pay SandRidge any amounts that SandRidge is required to pay such counterparties. Second, the trust will enter into hedge contracts directly with unaffiliated hedge counterparties. As a party to these contracts, the trust will receive payments directly from its counterparties, and be required to pay any amounts owed directly to its counterparties. Under the derivatives agreement, as Development Wells are drilled, SandRidge will have the right to novate to the trust any of the SandRidge-provided hedges, or to replace them with hedges executed by the trust directly with counterparties, as long as the hedging effects of the assigned or replacement hedges are economically equivalent to the hedging effects of the SandRidge-provided hedges, the counterparties to the assigned or replacement hedges have a corporate credit rating equal to or better than A-/A3 as rated by Standard and Poor's or Moody's and the counterparties to the existing hedges approve.

        The trust's counterparty under the derivatives agreement is SandRidge, whose hedge counterparties will be institutions with corporate credit ratings equal to or better than A-/A3. The counterparties to the trust's direct hedging contracts will also be institutions with corporate credit ratings of at least A/A2. In the event that one or more counterparties to the trust's hedging arrangements default on their obligations to make payments under such arrangements, the cash distributions to the trust unitholders could be materially reduced as the hedge payments are intended to provide additional cash to the trust during periods of lower oil prices. SandRidge will not be required to pay the trust to the extent of payment defaults by SandRidge's hedge contract counterparties. SandRidge will also have authority, in its role as hedge manager to the trust, to terminate, restructure or otherwise modify a portion of the trust's hedge contracts to the extent that SandRidge reasonably determines that the volumes hedged under such portion of the contracts exceed, or are expected to exceed, estimated production attributable to the trust's royalty interests over the periods hedged. Except in the limited circumstances involving the restructuring of an existing hedge, the trust will not have the ability to enter into additional hedges on its own and, accordingly, after the expiration of the hedging arrangements in        , there will be no hedges going forward. For more information on SandRidge's role as hedge manager for the trust, please see "—Administrative Services Agreement."

        The trust's obligations to the counterparties under its direct hedge contracts will be secured by a first priority lien on the trust's royalty interest in the Underlying Properties. In addition, the trust's direct hedge

Table of Contents

contracts will contain a prohibition on the trust granting additional liens on its royalty interest in the Underlying Properties, other than customary permitted liens and liens in favor of the trustee.

        Under the combined hedging arrangements, approximately            % of the expected production and            % of the expected revenues upon which the target distributions are based from                        through            will be hedged. All of the hedge contracts relate to oil production. Expressed in terms of oil production alone, approximately            % of the estimated oil production from            through            will be hedged. The remaining estimated production of oil during that time, all production of natural gas during that time, and all production after such time will not be hedged.

        The following table illustrates the type of contract, notional amount and weighted average fixed price for the oil hedge contracts that the trust will enter into directly or that SandRidge will pass through to the trust under the derivatives agreement. All of the hedging contracts will be price swap contracts.

Administrative Services Agreement

        In connection with the closing of this offering, the trust will enter into an administrative services agreement with SandRidge pursuant to which SandRidge will provide the trust with certain accounting, tax preparation, bookkeeping and informational services related to the royalty interests and the registration rights agreement.

        Additionally, the administrative services agreement will designate SandRidge as the trust's hedge manager, pursuant to which SandRidge will have authority to administer the hedge contracts underlying the derivatives agreement, and, on behalf of the trust, to administer the trust's direct hedge contracts. As hedge manager, SandRidge will also have authority, in its discretion, to terminate, restructure or otherwise modify any or all of such hedge contracts to the extent that SandRidge reasonably determines that the volumes hedged under such contracts exceed, or are expected to exceed, estimated production attributable to the trust's royalty interests over the periods hedged. SandRidge will be required to use commercially reasonable efforts to effect such modifications to the hedge contracts in a manner that is cash neutral to the trust. For example, hedge prices may be reset and/or a portion of hedged volumes may be reallocated to different periods. However, in fulfilling its role as hedge manager, SandRidge will not act as a fiduciary for the trust, will have no affirmative duty to modify any of the trust's hedges, and will have no liability to the trust in connection with SandRidge's failure to modify, or any affirmative modification of, any of the trust's hedges. Moreover, SandRidge will be indemnified by the trust for any actions it takes in this regard.

        In return for the services provided by SandRidge to the trust under the administrative services agreement, the trust will pay SandRidge, on a quarterly basis, a total annual fee of $300,000. SandRidge will also be entitled to receive reimbursement for its actual out-of-pocket fees, costs and expenses incurred in connection with the provision of any of the services under the agreement.

        The administrative services agreement will terminate upon the earliest to occur of: (a) the date the trust shall have dissolved and commenced winding up in accordance with the trust agreement, (b) the date that all of the royalty interests have been terminated or are no longer held by the trust, (c) with respect to services to be provided with respect to any Underlying Properties being transferred by SandRidge, the date that either SandRidge or the trustee may designate by delivering 90-days prior written notice, provided that SandRidge's drilling obligation has been completed and the transferee of such Underlying Properties assumes responsibility to perform the services in place of SandRidge and (d) a date mutually agreed by SandRidge and the trustee.

TARGET DISTRIBUTIONS AND SUBORDINATION AND INCENTIVE THRESHOLDS

        SandRidge will convey to the trust royalty interests in specified oil and natural gas properties in the AMI. The PDP Royalty Interest will entitle the trust to receive 80% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Producing Wells. The Development Royalty Interest will entitle the trust to receive 70% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of future production of oil and natural gas attributable to SandRidge's net revenue interest in the Development Wells.

        The amount of trust revenues and cash distributions to trust unitholders will depend on:

        SandRidge has calculated quarterly target levels of cash distributions for the life of the trust. Such target distribution levels are set forth on Annex B to this prospectus. The target distributions were prepared by SandRidge on a cash basis based on assumptions of production volumes, pricing and other assumptions that are described below in "—Significant Assumptions Used to Calculate the Target Distributions." The production forecasts are estimates prepared by Netherland Sewell and have been used to calculate target distributions. Actual cash distributions may vary from those presented. SandRidge will pay to the trust each quarter an amount equal to the trust's royalty interest in the proceeds of production from the Underlying Properties received during the calendar quarter most recently ended (after deducting post-production costs and any applicable taxes). The trust, in turn, will make quarterly cash distributions of substantially all of its quarterly cash receipts, after deduction of fees and expenses for the administration of the trust, to holders of trust units.

        The first distribution, which will cover the first quarter of 2012, is expected to be made on or about May 30, 2012 to record unitholders as of May 15, 2012. The trustee intends to withhold $1.0 million from the first distribution to establish a cash reserve available to pay trust administrative expenses. If the trustee uses such cash reserve to pay for trust administrative expenses, the reserve must be replenished before any further quarterly distributions are made to trust unitholders. Due to the timing of the payment of production proceeds to the trust, the trust expects that the first distribution will include sales for oil and natural gas for two months. Thereafter, quarterly distributions will generally include royalties on sales of oil and natural gas for three months, including the first two months of the quarter just ended as well as the last month of the immediately preceding quarter. Because payments to the trust will be generated by depleting assets and production from the Underlying Properties will diminish over time, a portion of each distribution will represent a return of your original investment.

        In order to provide support for cash distributions on the common units, SandRidge has agreed to subordinate 12,062,500 of the trust units it will retain following this offering, which will constitute 25% of the total trust units outstanding. The subordinated units will be entitled to receive pro rata distributions from the trust if and to the extent there is sufficient cash to provide a cash distribution on the common units that is no less than the applicable quarterly subordination threshold. If there is not sufficient cash to fund such a distribution on all trust units, the distribution to be made with respect to the subordinated units will be reduced or eliminated in order to make a distribution, to the extent possible, of up to the subordination threshold amount on the common units. Each applicable quarterly subordination threshold

51


Table of Contents

is 20% below the target distribution level for the corresponding quarter, as reflected on Annex B. In exchange for agreeing to subordinate these trust units, and in order to provide additional financial incentive to SandRidge to perform its drilling obligation and operations on the Underlying Properties in an efficient and cost-effective manner, SandRidge will be entitled to receive incentive distributions equal to 50% of the amount by which the cash available for distribution on all of the trust units in any quarter during the subordination period exceeds the target distribution for such quarter by more than 20%. SandRidge's right to receive incentive distributions will terminate upon the expiration of the subordination period.

        The subordinated units will automatically convert into common units on a one-for-one basis, and SandRidge's right to receive incentive distributions will terminate, at the end of the fourth full calendar quarter following SandRidge's satisfaction of its drilling obligation with respect to the Development Wells. SandRidge currently expects that it will complete its drilling obligation on or before December 31, 2015 and that, accordingly, the subordinated units will convert into common units on or before December 31, 2016. SandRidge is obligated to complete its drilling obligation by December 31, 2016, in which event the subordinated units would convert into common units on or before December 31, 2017.

        SandRidge's management has prepared the prospective financial information set forth below to present the target distributions to the holders of the trust units based on the estimates and assumptions described below. The accompanying prospective financial information was not prepared with a view toward complying with the guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants with respect to preparation and presentation of prospective financial information.

Includes proceeds attributable to the first two months of production from January 1, 2012 to February 29, 2012, and gives effect to $1.0 million of reserves for general and administrative expenses withheld by the trustee and additional administrative costs relating to the formation of the trust.

        SandRidge has prepared the operational and financial information set forth above and below in order to present the target distributions attributable to the oil and natural gas sales volumes reflected in the reserve report. The target distributions, in the view of SandRidge's management, were prepared on a

53


Table of Contents

reasonable basis based on the assumptions outlined in "—Significant Assumptions Used to Calculate the Target Distributions."

        The operational and financial targets outlined below should not be relied upon as being necessarily indicative of future results. Neither SandRidge nor the trust undertakes any obligation to update the financial forecast to reflect events or circumstances after the date of this prospectus and readers of this prospectus are cautioned not to place undue reliance on this financial information.

        The projections and assumptions on which the operational and financial targets are based are subject to significant uncertainties, many of which are beyond the control of SandRidge and the trust. Actual cash distributions to trust unitholders, therefore, could vary significantly based upon events or conditions occurring that are different from the events or conditions assumed to occur for purposes of these operational and financial targets.

        Cash distributions to trust unitholders will be particularly sensitive to fluctuations in oil and natural gas prices and production volumes. See "—Sensitivity of Target Distributions to Oil and Natural Gas Prices and Volumes," which shows estimated effects to cash distributions through December 31, 2012 from changes in assumed realized oil and natural gas prices as well as changes in estimated production volumes attributable to probable reserves, which are, by definition, less certain to be produced than are proved reserves. As a result of typical production declines for oil and natural gas properties, production estimates generally decrease from year to year. However, the production estimates included in the table below reflect that these declines are expected to be offset by additional production from Development Wells as they are completed and begin to produce. The timing of the completion of, and the amount of production attributable to, the Development Wells are substantially dependent on SandRidge executing its drilling plans with respect to the drilling and completion of the Development Wells in a manner substantially similar to those underlying the assumptions used in establishing these target distributions. In addition, the completion of SandRidge's drilling obligation will depend, in part, on the completion of drilling for certain Development Wells by third parties, over whom SandRidge has no control, in a manner consistent with the assumptions used in establishing these target distributions. Please see "Risk Factors" for risks relating to the timing of drilling and amount of production attributable to the Development Wells. As a result of these factors, the target distributions shown in the tables below are not necessarily indicative of actual distributions to be made in future years.

        Because payments to the trust will be generated by depleting assets and production from the Underlying Properties will diminish over time, a portion of each distribution will represent a return of your original investment. See "Risk Factors—The oil and natural gas reserves estimated to be attributable to the Underlying Properties of the trust are depleting assets and production from those reserves will diminish over time. Furthermore, the trust is precluded from acquiring other oil and gas properties or royalty interests to replace the depleting assets and production."

Unaudited Pro Forma Distributable Income

        If the conveyance of the royalty interests and the closing of this offering had taken place on January 1, 2011, pro forma distributable income of the trust for the nine-month period ended September 30, 2011 would have been $16.6 million or $.34 per trust unit. There were significantly fewer producing wells in the Underlying Properties in 2011 compared to the number of wells in the Underlying Properties that are

56


Table of Contents

anticipated to be completed and producing during 2012. Production of oil and natural gas from the Underlying Properties has increased during each quarter in 2011 and it is anticipated that production will continue to increase in 2012 as more wells are completed and begin to produce. As a result, it is anticipated that cash available for distribution in quarterly periods in 2012 will be in excess of the historical amounts shown in the pro forma statements for the period ended September 30, 2011. This increasing level of production is reflected in the estimated cash available for distribution in quarterly periods during 2012. Estimated production amounts reflected in the reserve reports prepared by Netherland Sewell are consistent with actual production from the Producing Wells for the nine-month period ended September 30, 2011. For a calculation of the pro forma distributable income of the trust for these periods, please read "Unaudited Pro Forma Financial Information" beginning on page F-14.

Significant Assumptions Used to Calculate the Target Distributions

        In preparing the target distributions and subordination and incentive threshold tables above and sensitivity tables below, the revenues and expenses of the trust were calculated based on the terms of the conveyances creating the trust's royalty interests using the following assumptions and those set forth above under "Target Distributions and Subordination and Incentive Thresholds." These calculations are described under "Description of the Royalty Interests."

        Production Estimates.    Production estimates for each of the quarters during the life of the trust are based on the reserve report. The estimates of reserves and production relating to the Underlying Properties and the royalty interests included in the reserve report have been made in accordance with the SEC's rules for reserve reporting. Production attributable to the royalty interests from the Underlying Properties for the 12-months ending December 31, 2012 is estimated to be 2,018 MBoe. However, due to the timing of the payment of production proceeds to the trust, the production attributable to the distributions for the 12-months ending December 31, 2012 will be for the 11-months ending November 30, 2012, estimated to be 1,842 MBoe. The estimated production in the forecast period gives effect to the drilling and completion by SandRidge of approximately 49 Development Wells per year during the four-year drilling period, and the completion by SandRidge of its drilling obligation to the trust of 206 Development Wells on or before December 31, 2015. As a reasonably prudent operator, SandRidge is obligated to drill and complete the Development Wells consistent with the drilling and completion techniques used in the Producing Wells to enhance oil and natural gas recovery in a cost effective manner. See "—Oil Prices" and "—Natural Gas Prices" below for a description of changes in production due to price variations. Differing levels of production will result in different levels of distributions and cash returns.

        If oil and natural gas prices decline, the operators of producing oil and natural gas properties may elect to reduce or completely suspend production. SandRidge is required under the applicable conveyance to act as a reasonably prudent operator with respect to the Underlying Properties under the same or similar circumstances as it would act if it were acting with respect to its own properties, disregarding the existence of the royalty interests as burdens affecting such properties. No adjustments have been made to estimated production in the tables above to reflect potential reductions or suspensions of production by SandRidge or third party operators.

        Oil Prices.    The assumed oil prices utilized for purposes of preparing the target distributions are based on monthly NYMEX forward pricing for the period ending December 31, 2014 and assumed price increases after December 31, 2014 of 2.5% annually, capped at $120.00 per Bbl. Using these assumptions, the price per Bbl would reach the $120.00 per Bbl cap in January 2025. The table below sets forth NYMEX forward pricing as of January 3, 2012 for the period ending December 31, 2014.

        Natural Gas Prices.    The assumed natural gas prices utilized for purposes of preparing the target distributions are based on NYMEX forward pricing for the period ending December 31, 2014 and assumed price increases after December 31, 2014 of 2.5% annually, capped at $7.00 per MMBtu. Using these assumptions, the price per MMBtu would reach the $7.00 per MMBtu cap in September 2031. The table below sets forth NYMEX forward pricing as of January 3, 2012 for the period ending December 31, 2014.

        Hedging.    The trust will enter into hedge contracts directly with unaffiliated counterparties. Additionally, SandRidge will enter into a derivatives agreement with the trust in order to transfer to the trust the economic effect of the hedge contracts entered into between SandRidge and unaffiliated counterparties. Pursuant to these arrangements, approximately            % of the expected production and            % of the expected revenues upon which the target distributions are based from                        through                         will be hedged. All of the hedge contracts relate to oil production. See "The Trust—Hedging Arrangements." However, the oil prices used for purposes of preparing the target distributions set forth in the prospectus do not reflect any hedging assumptions.

58


Table of Contents

        Differentials.    Proceeds to the trust will be calculated based on the actual price realized by SandRidge for oil and natural gas produced, which will differ from NYMEX prices as a result of:

        These charges are collectively referred to as pricing "differentials" from NYMEX pricing.

        To prepare the target distributions, assumed differentials were subtracted from the NYMEX prices shown in the tables above, based on an analysis by SandRidge of historical realized prices for production from the region. The estimated realized prices for natural gas equal the NYMEX futures prices for natural gas, and the estimated realized prices for oil assume a $5.03 per barrel negative differential from the NYMEX futures prices for oil.

        There can be no assurance that realized prices in the future will be the same as historical realized prices or the assumed realized prices used to prepare the target distributions.

        Administrative Expense.    Trust administrative expense per year is estimated to be approximately $1.3 million, although such costs could be greater or less depending on future events that cannot be predicted. Included in this annual estimate are annual administrative fees of $150,000 for the trustee and $300,000 for SandRidge. The remaining $850,000 of the trust's estimated administrative expenses are comprised of filing fees and professional services fees for audit and tax compliance services, reserve estimation services and legal fees. The estimate was based on estimates provided by service providers, SandRidge's experience with its other royalty trusts, and SandRidge's experience as a public company. It has been assumed that the annual fee to SandRidge will remain flat for the life of the trust, the annual fee to the trustee will escalate at 2.5% after the fourth quarter of 2017, and the remaining estimated costs of $850,000 will escalate at a rate of 2.5% annually starting in the first quarter of 2014. It has been assumed that the trust will also pay, out of the first cash payment received by the trust, the trustee's and Delaware trustee's legal expenses incurred in forming the trust as well as the trustee's acceptance fee in the amount of $10,000. These costs will be deducted by the trust before distributions are made to trust unitholders.

        Trustee's Cash Reserve.    It has been assumed that the trustee will withhold $1.0 million from the first distribution to unitholders to establish a cash reserve available for potential administrative expenses of the trust. No other cash reserves have been assumed.

        Tax Treatment of Royalty Interests.    For U.S. federal income tax purposes, the Term PDP Royalty will, and the Term Development Royalty should, be treated as debt instruments. Accordingly, the Term Royalties will be subject to the original issue discount, or OID, rules of the Internal Revenue Code, which require that payments made to the trust with respect to the Term Royalties will be treated first as consisting of a payment of interest to the extent of interest deemed accrued under the OID rules at the "comparable yield" SandRidge would be expected to pay, as of the initial issue date, on a fixed rate debt security with no contingent payments but otherwise comparable terms and conditions, and the excess, if any, will be treated as a payment of principal (which is non-taxable). For federal income tax purposes, the Perpetual PDP Royalties will be, and the Perpetual Development Royalties should be, treated as mineral royalty interests, which give rise to ordinary income subject to depletion.

        Timing of Actual Cash Distributions.    Quarterly cash distributions will be made on or about the 60th day following the end of each calendar quarter to unitholders of record on or about the 45th day following each calendar quarter. Due to the timing of SandRidge's receipt of cash for production, it has been assumed that cash distributions for each quarter will include production from the first two months of the

59


Table of Contents

quarter just ended as well as the last month of the immediately preceding quarter. The first distribution, which will cover the first quarter of 2012, is expected to be made on or about May 30, 2012 to record unitholders as of May 15, 2012, and will include sales for oil and natural gas for two month period from January 1, 2012 through February 29, 2012. Thereafter, quarterly distributions will generally relate to production of oil and natural gas for a three month period, including one month of the prior quarter.

        Applicable Taxes.    Oklahoma levies a tax on the production of oil and natural gas in the state. Under current law, a reduced rate of production tax is available for the first four years of a horizontal well's production so long as the well is producing before July 1, 2015. Accordingly, it has been assumed that the effective rate of Oklahoma production tax on the oil and gas attributable to the trust will be approximately 1.0% for the first four years of production for each well, and approximately 7.0% thereafter.

        Kansas levies an 8% mineral severance tax on the taxable gross value of oil and natural gas production. However, for a period of 24 months following the month in which oil or natural gas is first produced from a new pool, such production is exempt from the mineral severance tax. In addition to the mineral severance tax, producing oil and natural gas wells and associated equipment are generally considered taxable personal property subject to Kansas property taxes. Effective composite property tax rates within the section of the AMI located in Kansas will vary by year and taxing authority but are expected to range between 3% and 5% of the taxable value of the oil and natural gas reserves owned by the trust. Persons who are liable for both property and mineral severance taxes, as would be the trust, are allowed a credit against the mineral severance tax in an amount equal to 3.67% of the taxable gross value, effectively reducing the mineral severance tax to 4.33%.

        It is assumed that 190 Development Wells will be drilled in Oklahoma and 16 Development Wells will be drilled in Kansas. If a different number of Development Wells is drilled in each jurisdiction, applicable taxes would be affected commensurately.

        Incentive Distributions.    To the extent that the trust has cash available for distribution in excess of the incentive thresholds during the subordination period, SandRidge will be entitled to receive 50% of such cash as incentive distributions. The incentive distributions terminate upon completion of the subordination period.

        Valuation of Perpetual Royalties.    In estimating the cash available for distribution to trust unitholders following the Termination Date, the royalty interests attributable to the Perpetual Royalties, which the trust will own on the Termination Date and subsequently sell, were valued at $184.7 million as of the Termination Date. This value was determined using a discounted cash flow analysis assuming:

        The actual value of the Perpetual Royalties sold by the trust following the Termination Date and the proceeds available for distribution to trust unitholders from such sale will depend on numerous factors out of SandRidge's or the trust's control, including the estimated future production of the reserves attributable to the Perpetual Royalties on the Termination Date, current and expected commodity prices as of the Termination Date and the discount rate employed by prospective purchasers.

Sensitivity of Target Distributions to Changes in Oil and Natural Gas Prices and Volumes

        The amount of revenues of the trust and cash distributions to the trust unitholders will be directly dependent on the sales price for oil and natural gas sold, the volumes of oil and natural gas produced and,

60


Table of Contents

to some degree, variations in property and production taxes, if any, and post-production costs. The following tables demonstrate the effect that changes in the estimated oil and natural gas production for the forecast period ending December 31, 2012 as reflected in the reserve report and the impact that fluctuations in assumed realized oil and natural gas prices could have on cash distributions to the trust unitholders.

        These tables set forth the sensitivity of annual cash distributions per trust unit for the forecast period ending December 31, 2012 based upon:

        The tables give effect to the subordination and incentive distribution features that are contained in the terms of the trust. For a description of the way in which those features would impact trust unitholders' distributions, please see "Target Distributions and Subordination and Incentive Thresholds."

        The following tables are not a projection or forecast of the actual or estimated results from an investment in the common units. The purpose of these tables is to illustrate the sensitivity of cash distributions to changes in oil and natural gas production levels and the price of oil and natural gas. There is no assurance that the assumptions described below will actually occur or that oil and natural gas production levels and the prices of oil and natural gas will not change by amounts different from those shown in the tables.

        The hedging arrangements for the trust will be in effect only through            , and thus there is likely to be greater fluctuation in cash distributions resulting from fluctuations in realized oil and natural gas prices in periods subsequent to such time. See "Risk Factors" for a discussion of various items that could impact production levels and the price of oil and natural gas.

        These distributions are sensitized to both assumed NYMEX oil and natural gas prices as well as the assumed production from the trust properties. The quarterly distributions in the tables below are based on assumptions outlined in "—Significant Assumptions Used to Calculate the Target Distributions." The tables set forth below provide examples of possible distributions for the quarters ending March 31, 2012, June 30, 2012, September 30, 2012 and December 31, 2012 based on various NYMEX pricing and production assumptions.

        For scenarios in these tables that involve lower NYMEX oil or natural gas prices and production volumes, as applicable, the quarterly distribution per unit does not fall below the subordination threshold because the subordinated units support the common distributions.

61


Table of Contents

        For each table, the assumed NYMEX oil price per Bbl or natural gas price per MMBtu, as applicable, used to estimate quarterly distributions is also the assumed NYMEX oil price or gas price for all previous quarters. The distributions below do not reflect any hedging assumptions.

THE UNDERLYING PROPERTIES

        The Underlying Properties consist of the oil and gas leasehold interest owned by SandRidge in the Mississippian formation in Noble, Kay, Alfalfa, Grant and Woods counties in northern Oklahoma and Harper, Comanche, Sumner and Barber counties in southern Kansas arising under leases and farmout agreements related to properties from which the PDP Royalty Interest and the Development Royalty Interest will be conveyed. The Underlying Properties consist of approximately 81,200 gross acres (53,000 net acres). As of December 31, 2011 and after giving effect to the conveyance of the PDP Royalty Interest and the Development Royalty Interest to the trust, the total proved reserves estimated to be attributable to the trust were 26.1 MMBoe. This amount includes 10.2 MMBoe attributable to the PDP Royalty Interest and 15.9 MMBoe attributable to the Development Royalty Interest. In addition, as of December 31, 2011 and after giving effect to the conveyance of the PDP Royalty Interest and the Development Royalty Interest to the trust, there were 9.8 MMBoe of probable reserves estimated to be attributable to the trust, all of which was attributable to the Development Royalty Interest. Please see "—Oil and Natural Gas Reserves" and "—The Reserve Report" for information about the estimated reserves attributable to the trust. The reserves attributable to the trust's royalty interests include the reserves that are expected to be produced from the Mississippian formation during the 20-year period in which the trust owns the royalty interests as well as the residual interest in the reserves that the trust will sell on or shortly following the Termination Date.

Overview of the Underlying Properties

        The Underlying Properties are located in northern Oklahoma and southern Kansas in the Mississippian formation, which is an expansive carbonate hydrocarbon system located on the Anadarko Shelf. The top of the formation is encountered between 4,000 feet and 7,000 feet and lies stratigraphically between the Pennsylvanian-aged Morrow formation and the Devonian-aged Woodford Shale formation. The Mississippian formation can reach 1,000 feet in gross thickness and the targeted porosity zone is between 50 and 100 feet in thickness. The formation's geology is well understood as a result of the thousands of vertical wells drilled and produced there since the 1940s, including approximately 73 vertical wells drilled on the Underlying Properties, and over 400 horizontal wells drilled in the region in the Mississippian formation.

        In 2007, the application of horizontal cased-hole drilling and multi-stage hydraulic fracturing treatments demonstrated the potential for extracting significant additional quantities of oil and natural gas from the formation. Since the beginning of 2009, there have been over 400 horizontal wells drilled in the Mississippian formation in northern Oklahoma and southern Kansas, including 205 drilled by SandRidge. From December 31, 2010 to December 31, 2011, the number of SandRidge's producing horizontal wells in the Mississippian formation increased from 44 to 174. As of December 31, 2011, there were approximately 43 horizontal rigs drilling in the formation, with 19 of those rigs drilling for SandRidge. While horizontal wells are more expensive than vertical wells, a horizontal well bore increases the production of hydrocarbons and adds significant recoverable reserves per well. In addition, one horizontal well is the effective equivalent of several vertical wells, and as a result better returns on drilling investments may be achieved with horizontal drilling.

        As of December 31, 2011, SandRidge had approximately 1.5 million net acres leased in the Mississippian formation in northern Oklahoma and Kansas.

Historical Results from the Producing Wells

        The following table provides revenues and direct operating expenses relating to the Producing Wells for the nine-month period ended September 30, 2011, derived from the Underlying Properties' statement of revenues and direct operating expenses included elsewhere in this prospectus. As of September 30, 2011, there were 38 Producing Wells, the first of which began producing in February 2011. As a result, the information in the table set forth below will not be comparable to the trust's results going forward as SandRidge completes additional Producing Wells. The information in the table below does not reflect the formation of the trust or the conveyance of the PDP Royalty Interest to the trust. The selected financial data presented below should be read in conjunction with the audited statement of revenues and direct operating expenses of the Underlying Properties, the related notes and "—Discussion and Analysis of Historical Results from the Producing Wells" included elsewhere in this prospectus and the discussion of SandRidge's business and related Management's Discussion and Analysis of Financial Condition and Results of Operations of SandRidge Energy, Inc. incorporated by reference in this prospectus.

Discussion and Analysis of Historical Results from the Producing Wells

        Nine months ended September 30, 2011.    During the nine months ended September 30, 2011, SandRidge drilled or participated in the drilling of 47 wells included in the Underlying Properties, including two wells spud in late 2010. The first of these wells began production in February 2011 with an additional 37 wells beginning production during the first nine months of 2011. Of the remaining wells drilled during this period, three had been completed and were awaiting infrastructure and six were awaiting completion at September 30, 2011. The completed wells, including those awaiting infrastructure, were drilled with an average perforated interval length of 4,300 feet and completed with an average of 8.6 fracture stimulations per well. Aggregate monthly production net to SandRidge's interest ranged during this period from a low of approximately 120 Boe during February 2011 to a high of approximately 143,000 Boe during September 2011. Total volumes produced and sold during the nine months ended September 30, 2011 from the 38 wells producing during the period was approximately 396,000 Boe.

        The average sales prices received for oil and natural gas production during the nine months ended September 30, 2011 were $85.64 per barrel of oil and $4.59 per Mcf, respectively, before deduction of any post-production costs or operating expenses. Prices received ranged from a low of $75.80 per barrel in August 2011 to a high of $103.35 per barrel in April 2011 for oil sales and from a low of $4.16 per Mcf in March 2011 to a high of $4.83 per Mcf in May 2011 for natural gas sales. Post-production costs were $2.48 per Boe produced and totaled approximately $983,000 for the nine months ended September 30, 2011. Lease operating expenses were $11.09 per Boe produced and totaled approximately $4,391,000 for the same period. Revenues less direct operating expenses were approximately $17,588,000 for the nine months ended September 30, 2011.

        During the nine months ended September 30, 2011, SandRidge invested approximately $555,000 in the development of one well that was classified as proved undeveloped at December 31, 2010. This well was classified as proved developed at September 30, 2011. As of September 30, 2011, all of the 38 producing wells were expected to pay out their drilling and completion costs.

Oil and Natural Gas Reserves

        Netherland Sewell estimated oil and natural gas reserves attributable to the Underlying Properties as of December 31, 2011. Numerous uncertainties are inherent in estimating reserve volumes and values, and the estimates are subject to change as additional information becomes available. The reserves actually recovered and the timing of production of the reserves may vary significantly from the original estimates.

        Proved and probable reserves of the Underlying Properties and royalty interests.    The following table sets forth certain estimated proved and probable reserves and their PV-10 value as of December 31, 2011 attributable to the Underlying Properties and the royalty interests, in each case derived from the reserve report. The reserve report was prepared by Netherland Sewell in accordance with criteria established by the SEC.

        Reserve quantities attributable to the royalty interests are calculated by multiplying the gross reserves for each property by the royalty interest assigned to the trust in each property. The net revenues attributable to the trust's reserves are net of an assumed level of post-production costs based on historical results. The reserves related to the Underlying Properties include all of the proved and probable reserves expected to be economically produced during the life of the properties. The reserves and revenues attributable to the trust's interests include only the reserves attributable to the Underlying Properties that are expected to be produced within the 20-year period in which the trust owns the Term Royalties as well as the residual interest in the reserves that the trust will own on the Termination Date attributable to the Perpetual Royalties.

Table of Contents

        Proved reserves are reserves that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward from known reservoirs under existing economic conditions, operating methods and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain. Probable reserves are reserves that are less certain to be recovered than proved reserves but that, together with proved reserves, are at least as likely as not to be recovered. Estimates of probable reserves are subject to substantially greater risk of not actually being realized. For a discussion of the uncertainties associated with estimates of probable reserves, see "Risk Factors—Actual reserves and future production may be less than current estimates, which could reduce cash distributions by the trust and the value of the trust units."

The proved and probable reserves were determined using a 12-month unweighted arithmetic average of the first-day-of-the-month prices for oil and natural gas for the period from December 31, 2010 through December 31, 2011, without giving effect to derivative transactions, and were held constant for the life of the properties. The prices used in the reserve report, as well as SandRidge's internal reports, yield weighted average prices at the wellhead, which are based on first-day-of-the-month reference prices and adjusted for transportation and regional price differentials. The reference prices and the equivalent weighted average wellhead prices are both presented in the table below.

PV-10 is the present value of estimated future net revenue to be generated from the production of proved and probable reserves, discounted using an annual discount rate of 10%, calculated without deducting future income taxes. PV-10 is a non-GAAP financial measure and generally differs from standardized measure of discounted net cash flows, or Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. Because the historical financial information related to the Underlying Properties consists solely of revenues and direct operating expenses and does not include the effect of income taxes, we expect the PV-10 and Standardized Measure attributable to the Underlying Properties to be equivalent. Because the trust will not bear federal income tax expense, we also expect the PV-10 and Standardized Measure attributable to the royalty interests to be equivalent. Neither PV-10 nor Standardized Measure represents an estimate of the fair market value of the Underlying Properties or the royalty interests. SandRidge and others in the industry use PV-10 as a measure to compare the relative size and value of proved and probable reserves held by companies without regard to the specific tax characteristics of such entities. PV-10 for the royalty interests has been calculated without deduction for production and development costs, as the trust will not bear those costs.

Table of Contents

        Information concerning historical changes in net proved reserves attributable to the Underlying Properties, and the calculation of the standardized measure of discounted future net revenues related thereto, is contained in the historical financial statements and pro forma financial information contained elsewhere in this prospectus. SandRidge has not filed reserve estimates covering the Underlying Properties with any other federal authority or agency.

The Reserve Report

        All of the oil and natural gas reserves as of December 31, 2011 in this prospectus were estimated by Netherland Sewell. The process to review and estimate the reserves began with a SandRidge staff reservoir engineer collecting and verifying all pertinent data, including but not limited to well test data, production data, historical pricing, cost information, property ownership interests, reservoir data, geosciences data and non-confidential production data of relevant wells and operations in the area. This data was reviewed by various levels of SandRidge management for accuracy, before consultation with Netherland Sewell. These individuals consulted regularly with Netherland Sewell during the reserve estimation process to review properties, assumptions, and any new data available. Internal reserve estimates and methodologies were compared to those prepared by Netherland Sewell to test the reserve estimates and conclusions before the reserve estimates were included in this prospectus. Additionally, SandRidge's senior management reviewed and approved the reserve report contained herein.

        Internal Controls.    SandRidge's Executive Vice President—Reservoir Engineering is the technical person primarily responsible for overseeing the preparation of the company's reserve estimates, is the primary contact with Netherland Sewell and received the reserve report from Netherland Sewell. He has a Bachelor of Science degree in Mechanical Engineering with 30 years of practical industry experience, including 25 years of estimating and evaluating reserve information. In addition, SandRidge's Executive Vice President—Reservoir Engineering has been a certified professional engineer in the state of Oklahoma since 1988 and a member of the Society of Petroleum Engineers since 1980.

        SandRidge's Reservoir Engineering Department continually monitors asset performance and makes reserves estimate adjustments, as necessary, to ensure the most current reservoir information is reflected in reserves estimates. Reserve information includes production histories as well as other geologic, economic, ownership and engineering data. The department currently has a total of 21 full-time employees, comprised of eight degreed engineers and 13 engineering analysts/technicians with a minimum of a four-year degree in mathematics, economics, finance or other business or science fields.

        SandRidge maintains a continuous education program for engineers and technicians on new technologies and industry advancements and also offers refresher training on basic skill sets.

        In order to ensure the reliability of reserves estimates, internal controls observed within the reserve estimation process include:

        Each quarter, the Executive Vice President—Reservoir Engineering presents the status of SandRidge's reserves, including the reserves associated with the Underlying Properties, to the Executive Committee, which subsequently approves all changes. In the event the quarterly updated reserves estimates are disclosed, the aforementioned review process is evidenced by signatures from the Executive Vice President—Reservoir Engineering and the Chief Financial Officer.

        SandRidge's Reservoir Engineering Department works closely with its independent petroleum consultants at each fiscal year end to ensure the integrity, accuracy and timeliness of annual independent reserves estimates. These independently developed reserves estimates are adopted as SandRidge's corporate reserves and are reviewed by the Audit Committee, as well as the Chief Financial Officer, Senior Vice President of Accounting, Vice President of Internal Audit, Vice President of Financial Reporting, Treasurer and General Counsel. In addition to reviewing the independently developed reserve reports, the Audit Committee interviews the third-party engineer at Netherland Sewell primarily responsible for the reserve report.

        Technologies.    Under SEC rules, proved reserves are those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from known reservoirs from a given date forward, and under existing economic conditions, operating methods, and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. The term "reasonable certainty" implies a high degree of confidence that the quantities of oil and/or natural gas actually recovered will equal or exceed the estimate. Reasonable certainty can be established using techniques that have been proved effective by actual production from projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that establishes reasonable certainty. Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation.

        Under SEC rules, probable reserves are those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, are less certain to be recovered than proved reserves but which, together with proved reserves, are as likely as not to be recovered from a given date forward, and under existing economic conditions, operating methods, and government regulations prior to the time which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probalistic methods are used for the estimation.

        The estimates of proved developed reserves included in the reserve report were prepared using decline curve analysis to determine the reserves of individual Producing Wells.

        After estimating the reserves of each proved developed well, it was determined that a reasonable level of certainty exists with respect to the reserves that can be expected from close offset undeveloped wells in the field. The continuity of the formation across the AMI was established by reviewing electric well logs, geologically mapping the analogous reservoir and reviewing extensive production data from more than 1,200 vertical and 145 horizontal wells. The reserves attributable to the Producing Wells, which cover a wide area of the AMI, and the continuity of the formation over the AMI classification further supports proved undeveloped classification within close proximity to the Producing Wells. Data from both SandRidge and offset operators with which SandRidge has exchanged technical data demonstrate a consistency in this formation and the in situ fluids over an area much larger than the AMI. In addition, direct measurement from other producing wells was also used to confirm consistency in reservoir properties such as porosity, thickness and stratigraphic conformity.

        While vertical well control exists across all of the AMI most of the existing producing horizontal wells were drilled without benefit of a direct offset producing lateral section. These wells all encountered proven reserves in the Mississippian formation. The proved undeveloped locations within the AMI are generally

69


Table of Contents

direct parallel offsets to the horizontal wells drilled and producing to date. Of the proved undeveloped drilling locations identified in the reserve report, only approximately 16% are not direct offsets of other historically producing wells. Those approximately 16% proved undeveloped drilling locations are generally characterized as the second parallel offset and are interior to developed wells with commercial representative production.

        With respect to the Underlying Properties, the proved reserves are limited to the productive units and proved units that are reasonably certain of economic production when drilled, within the productive limits of the reservoir. The probable reserve locations do not meet the reasonable certainty criteria because they are not direct offsets to producing horizontal wells and are perimeter to developed wells, even though extensive geological and engineering data demonstrates a continuity of the formation. However, the probable reserves, together with proved reserves, are at least as likely as not to be recovered when drilled. The locations of proved undeveloped reserves and probable reserves were estimated using analogy to the representative proved developed wells. This analogy is based on 145 producing wells which provide the estimated reserves and production profile for the proved and probable undeveloped wells. There are 67 Producing Wells and 122 Development Well locations attributable to PUD reserves or 1.8 Development Well locations attributable to PUD reserves for every Producing Well. There are 84 Development Well locations attributable to probable reserves or 1.3 Development Well locations attributable to probable reserves for every Producing Well.

        Netherland Sewell.    Netherland Sewell, the independent petroleum engineering consultant, estimated all of the reserve information in this prospectus, in accordance with the definitions and guidelines of the SEC and, with the exception of the exclusion of future income taxes, conform to the FASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas. For the purposes of the reserve report, Netherland Sewell used technical and economic data including, but not limited to, well test data, production data, historical price and cost information, and property ownership interests. The reserves in the reserve report have been estimated using deterministic methods. Netherland Sewell used standard engineering and geosciences methods, or a combination of methods, such as performance analysis and analogy, that they considered to be appropriate and necessary to categorize and estimate reserves in accordance with SEC definitions and guidelines. A substantial portion of these reserves are for undeveloped locations and producing wells that lack sufficient production history upon which performance-related estimates of reserves can be based. Therefore, these reserves are based on estimates of reservoir volumes and recovery efficiencies along with analogy to properties with similar geologic and reservoir characteristics.

        Netherland Sewell's expertise is in petroleum engineering, geoscience, and petrophysical interpretation, not legal or accounting matters; they are not accountants, attorneys, or landmen. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, the conclusions from Netherland Sewell necessarily represent only informed professional judgment. The titles to the properties have not been examined by Netherland Sewell, nor has the actual degree or type of interest owned been independently confirmed. The data used in Netherland Sewell's estimates were obtained from SandRidge and the non-confidential files of Netherland Sewell and were accepted as accurate. Supporting geoscience, field performance, and work data are on file in their office.

        The qualifications of the technical person at Netherland Sewell primarily responsible for overseeing his firm's preparation of the reserve estimates presented herein include: 29 years of practical experience in petroleum engineering and more than 12 years estimating and evaluating reserve information; a registered professional engineer in the states of Texas, Louisiana and Wyoming; and a Bachelor of Science Degree in Civil Engineering and Masters in Business Administration. These qualifications meet or exceed the Society of Petroleum Engineers standard requirements to be a professionally qualified Reserve Estimator and Auditor.

Properties Underlying the Development Royalty Interest

        SandRidge's average net revenue interest in the oil and natural gas properties underlying the Development Royalty Interest is approximately 47.4%. The Development Royalty Interest will entitle the trust to receive 70% of the proceeds attributable to SandRidge's net revenue interest in future production of oil and natural gas resulting from the drilling of the Development Wells, with 35% of such proceeds attributable to the Term Development Royalty and 35% of such proceeds attributable to the Perpetual Development Royalty.

        SandRidge expects to operate approximately 67% of the Development Wells during the subordination period. Until such time as SandRidge has met its commitment to drill the Development Wells, SandRidge will covenant and agree not to drill and complete, and will not permit any other person within its control to drill and complete, any well in the AMI for its own account. Upon the trustee's release of the Drilling Support Lien, SandRidge will further agree not to drill and complete, and will not permit any other person within its control to drill and complete, any well in the AMI that will have a perforation that will be within 660 feet of any perforation of any Development Well or Producing Well during the time period in which any such well is producing.

        If SandRidge drills one or more Development Wells in which it has less than a 47.4% net revenue interest, it may drill, or cause to be drilled, additional wells above the planned number for the trust in order to make the total number of Development Wells equal 206. For instance, if SandRidge drilled one well in which it has a 40% net revenue interest, and such well was drilled to a perforated length of 3,000 feet, such well would count for purposes of the development agreement as only .72 Development Wells (i.e., 3,000 / 3,500 X 40% / 47.4%). In order to compensate for this, SandRidge could drill, or cause to be drilled, an additional well with a perforated length of 2,000 feet and a 23.2% net revenue interest so that the trust still received one Development Well. See "The Trust—Development Agreement and Drilling Support Lien."

        Prior to fulfilling its drilling obligation to the trust, SandRidge may in limited circumstances cause the trust to exchange leased acreage in the AMI subject to the royalty interests, free and clear of such royalty interests, for other leased acreage in the AMI or the sections adjacent to the AMI (but excluding any sections that comprise part of the Area of Mutual Interest with respect to SandRidge Mississippian Trust I), and to cause such leased acreage exchanged with the trust to be made subject to the royalty interests as set forth in the conveyances. Such adjacent sections are referred to as the "Development Area." In addition, if SandRidge acquires any additional leases or interests in the AMI prior to the completion of its drilling obligation, SandRidge may make such additional leases or interests subject to the royalty interests with respect to any Development Wells subsequently drilled on such acreage. If additional acreage in the Development Area becomes subject to the royalty interests, then the AMI will automatically expand without further action by SandRidge or the trust to include such additional acreage. However, the

72


Table of Contents

aggregate acreage attributable to the exchanged acreage or additional leases or interests that becomes subject to the royalty interests may not exceed five percent of the acreage initially subject to the royalty interests. See "Description of the Royalty Interests—Additional Features of the Royalty Interests—Exchange and Addition of Acreage" for more information.

Sale and Abandonment of the Underlying Properties

        SandRidge and any transferee will have the right to abandon its interest in any well or property comprising a portion of the Underlying Properties if, in its opinion, such well or property ceases to produce or is not capable of producing in commercially paying quantities. To reduce or eliminate the potential conflict of interest between SandRidge and the trust in determining whether a well is capable of producing in commercially paying quantities, SandRidge and any transferee, as applicable, will be required under the applicable conveyance to act in good faith and as a reasonably prudent operator in the AMI under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the royalty interests as a burden affecting such properties.

        After completion of its drilling obligation, SandRidge generally may sell all or a portion of its interests in the Underlying Properties, subject to and burdened by the royalty interests, without the consent of the trust unitholders. In addition, SandRidge may, without the consent of the trust unitholders, require the trust to release for sale royalty interests with an aggregate value to the trust not to exceed $5.0 million during any 12-month period. These releases will be made only in connection with a sale by SandRidge of Underlying Properties and are conditioned upon the trust receiving an amount equal to the fair value to the trust of such royalty interests. Any net sales proceeds paid to the trust are distributable to trust unitholders for the quarter in which they are received. SandRidge has not identified for sale any of the Underlying Properties.

Marketing and Post-Production Services

        Pursuant to the terms of the conveyances creating the royalty interests, SandRidge will have the responsibility to market, or cause to be marketed, the oil and natural gas production related to the Underlying Properties. The terms of the conveyances creating the royalty interests do not permit SandRidge to charge any marketing fee when determining the proceeds upon which the royalty payments will be calculated. As a result, the proceeds to the trust from the sales of oil and natural gas production from the Underlying Properties will be determined based on the same price (net of post-production costs) that SandRidge receives for oil and natural gas production attributable to SandRidge's remaining interest in the Underlying Properties.

        A wholly owned subsidiary of SandRidge markets the majority of SandRidge's operated production. Such subsidiary enters into oil and natural gas sales arrangements with large aggregators of supply and these arrangements may be on a month-to-month basis or may be for a term of up to one year or longer. The oil and natural gas are sold at a market price and subsequently any applicable post-production costs will be deducted. The primary aggregators of supply with whom SandRidge currently does business in the AMI are Atlas Pipeline Mid-Continent WestOk, LLC, Sunoco Partners Marketing & Terminals, L.P., and Gavilon, LLC.

        Following this offering, post-production costs will be deducted from proceeds paid to the trust. SandRidge may provide post-production services itself or contract with others to provide post-production services, including gathering, transportation, processing and other reasonable post-production services, including transportation on downstream interstate pipelines. Such post-production costs will be expressed either (1) as a cost per Bbl or MMBtu or (2) as a percentage of the gross production from a well. The trust's cash available for distribution will be reduced by SandRidge's deductions for these post-production costs.

        Post-production costs may be deducted by the ultimate purchaser of the oil and natural gas prior to payment being made to SandRidge or its marketing affiliate for such production. At other times, SandRidge or its marketing affiliate will make payments directly to the third parties providing such

73


Table of Contents

post-production services. In either instance, the trust's cash available for distribution will be reduced by the costs paid by SandRidge for such post-production services provided by third parties. If the post-production costs are expressed as a percentage of the gross production from a well, then the volume of production from that well actually available for sale is less the applicable percentage charged, and as a result the reserves associated with that well that are attributable to the royalty interest are reduced accordingly.

        The cost of marketing and post-production services is included within the assumed differentials from NYMEX pricing discussed above under "Target Distributions and Subordination and Incentive Thresholds."

        Regardless of whether the post-production costs are based upon a cost per Bbl or per MMBtu or a percentage of gross production from a well, such costs may increase or decrease in the future. The post-production costs attributable to third party arrangements may be costs established by arms-length negotiations or pursuant to a state or federal regulatory proceeding. SandRidge will be permitted to deduct from the proceeds available to the trust other post-production costs necessary to make the oil and natural gas from the Underlying Properties marketable, so long as such costs do not materially exceed the charges prevailing in the area for similar services.

        SandRidge expects to enter into oil and natural gas supply arrangements and post-production service arrangements for the oil and natural gas to be produced from the Development Wells that are similar to those in place with respect to the Producing Wells. Any new oil and natural gas supply arrangements or those entered into for providing post-production services, will be utilized in determining the proceeds for the Underlying Properties.

Title to Properties

        The Underlying Properties are subject to certain burdens that are described in more detail below. To the extent that these burdens and obligations affect SandRidge's rights to production and the value of production from the Underlying Properties, they have been taken into account in calculating the trust's interests and in estimating the size and the value of the reserves attributable to the royalty interests.

        SandRidge acquired its interests in the Underlying Properties through a variety of means, including through the acquisition of oil and natural gas leases by SandRidge directly from the mineral owner, through assignments of oil and natural gas leases to SandRidge by the lessee who originally obtained the leases from the mineral owner, through farmout agreements that grant SandRidge the right to earn interests in the properties covered by such agreements by drilling wells, and through acquisitions of other oil and natural gas interests by SandRidge.

        SandRidge's interests in the oil and natural gas properties comprising the Underlying Properties are typically subject, in one degree or another, to one or more of the following:

74


Table of Contents

        SandRidge believes that the burdens and obligations affecting the Underlying Properties and the royalty interests are conventional in the industry for similar properties. SandRidge also believes that the burdens and obligations do not, in the aggregate, materially interfere with the use of the Underlying Properties and will not materially adversely affect the value of the royalty interest.

        SandRidge believes that its title to the Underlying Properties is, and the trust's title to the royalty interests will be, good and defensible in accordance with standards generally accepted in the oil and gas industry, subject to such exceptions as are not so material as to detract substantially from the use or value of such properties or royalty interests. SandRidge has not necessarily obtained drilling title opinions on all of the Underlying Properties. SandRidge does not intend to perform any further title examination prior to the closing of the offering being made hereby. Prior to drilling of a Development Well, SandRidge intends to obtain a drilling title opinion to identify defects in title to the leasehold. Frequently, as a result of title examinations, certain curative work may be required to correct identified title defects, and such curative work entails time and expense. SandRidge will not be relieved of its obligation to drill a well if title defects are identified that prevent SandRidge from drilling in such drill site.

Insurance

        In accordance with industry practice, SandRidge maintains insurance against some, but not all, of the operating risks to which its business is exposed. SandRidge currently has insurance policies that include coverage for general liability (includes sudden and accidental pollution), physical damage to its oil and gas properties, operational control of offshore wells, aviation, auto liability, marine liability, worker's compensation and employer's liability, among other things. At the depths and in the areas in which SandRidge operates, and in light of the vertical and horizontal drilling that it undertakes, SandRidge typically does not encounter high pressures or extreme drilling conditions. Accordingly, SandRidge does not carry control of well insurance for onshore operations.

        Currently, SandRidge has general liability insurance coverage up to $1 million per occurrence, which includes sudden and accidental environmental liability coverage for the effects of pollution on third parties arising from its operations. SandRidge's insurance policies contain maximum policy limits and in most cases, deductibles (generally ranging from $25,000 to $1 million) that must be met prior to recovery. These insurance policies are subject to certain customary exclusions and limitations. In addition, SandRidge maintains $100 million in excess liability coverage, which is in addition to and triggered if the general liability per occurrence limit is reached.

        SandRidge requires all of its third-party contractors to sign master services agreements in which they agree to indemnify SandRidge for injuries and deaths of the service provider's employees as well as contractors and subcontractors hired by the service provider. Similarly, SandRidge generally agrees to indemnify each third-party contractor against claims made by employees of SandRidge and SandRidge's other contractors. Additionally, each party generally is responsible for damage to its own property.

        The third-party contractors that perform hydraulic fracturing operations for SandRidge sign the master services agreements containing the indemnification provisions noted above. SandRidge does not currently have any insurance policies in effect that are intended to provide coverage for losses solely related to hydraulic fracturing operations. However, SandRidge believes its general liability and excess liability insurance policies would cover third party claims related to hydraulic fracturing operations and associated legal expenses, in accordance with, and subject to, the terms of such policies.

        SandRidge re-evaluates the purchase of insurance, coverage limits and deductibles annually. Future insurance coverage for the oil and gas industry could increase in cost and may include higher deductibles or retentions. In addition, some forms of insurance may become unavailable in the future or unavailable on terms that are economically acceptable. No assurance can be given that SandRidge will be able to maintain insurance in the future at rates that it considers reasonable and SandRidge may elect to self-insure or maintain only catastrophic coverage for certain risks in the future.

Competition and Markets

        The oil and natural gas industry is highly competitive. SandRidge competes with major oil and gas companies and independent oil and gas companies for leases, equipment, personnel and markets for the sale of oil and natural gas. Many of these competitors are financially stronger than SandRidge, but even financially troubled competitors can affect the market because of their need to sell oil and natural gas at any price to attempt to maintain cash flow. The trust will be subject to the same competitive conditions as SandRidge and other companies in the oil and gas industry.

        Oil and natural gas compete with other forms of energy available to customers, primarily based on price. These alternate forms of energy include electricity, coal and fuel oils. Changes in the availability or price of oil and natural gas or other forms of energy, as well as business conditions, conservation, legislation, regulations and the ability to convert to alternate fuels and other forms of energy may affect the demand for oil and natural gas.

        Future price fluctuations for oil and natural gas will directly impact trust distributions, estimates of reserves attributable to the trust's interests, and estimated and actual future net revenues to the trust. In view of the many uncertainties that affect the supply and demand for oil and natural gas, neither the trust nor SandRidge can make reliable predictions of future supply and demand for oil and natural gas, future oil and natural gas prices or the effect of future oil and natural gas prices on the trust.

Regulation

        Oil and Natural Gas Regulation.    The availability, terms and cost of transportation significantly affect sales of oil and natural gas. The interstate transportation and sale for resale of oil and natural gas is subject to federal regulation, including regulation of the terms, conditions and rates for interstate transportation, storage and various other matters, primarily by the Federal Energy Regulatory Commission. Federal and state regulations govern the price and terms for access to oil and natural gas pipeline transportation. The Federal Energy Regulatory Commission's regulations for interstate oil and natural gas transmission in some circumstances may also affect the intrastate transportation of oil and natural gas.

        Sales of oil and natural gas are not currently regulated and are made at market prices. Although oil and natural gas prices are currently unregulated, Congress historically has been active in the area of oil and natural gas regulation. Neither SandRidge nor the trust can predict whether new legislation to regulate oil and natural gas prices might be proposed, what proposals, if any, might actually be enacted by Congress or state legislatures, and what effect, if any, the proposals might have on the operations of the Underlying Properties.

        Environmental Regulation.    The exploration, development and production of oil and natural gas are subject to federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. These laws and regulations may, among other things, require permits to conduct drilling, water withdrawal and waste disposal operations; govern the amounts and types of substances that may be disposed or released into the environment; limit or prohibit construction or drilling activities in sensitive areas such as wetlands, wilderness areas or areas inhabited by endangered or threatened species; require investigatory and remedial actions to mitigate pollution conditions arising from SandRidge's operations or attributable to former operations; and impose obligations to reclaim and abandon well sites and pits. Failure to comply with these laws and regulations may result in the assessment of sanctions, including monetary penalties, the imposition of remedial obligations and the issuance of orders enjoining operations in affected areas.

        The clear trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment, and thus, any changes in environmental laws and regulations or re-interpretation of enforcement policies that result in more stringent and costly construction, drilling, water management, completion, waste handling, storage, transport, disposal, or remediation requirements or emission or discharge limits could have a material adverse effect on the proceeds available to the trust under the royalty interests. Moreover, accidental releases or spills may occur in the course of SandRidge's operations on the Underlying Properties, and there can be no assurance that SandRidge will not incur

76


Table of Contents

significant costs and liabilities as a result of such releases or spills, including any third party claims for damage to property and natural resources or personal injury.

        The following is a summary of the more significant existing environmental, health and safety laws and regulations applicable to the oil and natural gas industry and for which compliance may have a material adverse impact on SandRidge's operation of the Underlying Properties.

        Hazardous Substances and Wastes.    The Comprehensive Environmental Response, Compensation and Liability Act, as amended ("CERCLA"), also known as the Superfund law and comparable state laws impose joint and several liability, without regard to fault or legality of conduct, on certain classes of persons who are considered to be responsible for the release of a "hazardous substance" into the environment. These persons include current and prior owners or operators of the site where the release occurred and entities that disposed or arranged for the disposal of the hazardous substances found at the site. Under CERCLA, these "responsible persons" may be subject to strict joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain environmental and health studies. In addition, it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances into the environment. CERCLA also authorizes the EPA and, in some instances, third parties to act in response to threats to the public health or the environment and to seek to recover from the responsible classes of persons the costs they incur. SandRidge generates materials in the course of its operations, including with respect to the Underlying Properties, that may be regulated as hazardous substances.

        SandRidge generates wastes that are subject to the requirements of the Resource Conservation and Recovery Act, as amended ("RCRA"), and comparable state statutes. RCRA imposes strict requirements on the generation, transportation, treatment, storage, disposal and cleanup of hazardous and non-hazardous wastes. Drilling fluids, produced waters and most of the other wastes associated with the exploration, production and development of crude oil and natural gas are currently exempt from regulation as hazardous wastes under RCRA. However, it is possible that certain oil and natural gas exploration and production wastes now classified as non-hazardous could be classified as hazardous wastes in the future. In September 2010, the Natural Resources Defense Council filed a petition for rulemaking with the EPA requesting reconsideration of the RCRA exemption for exploration, production, and development wastes. To date, the EPA has not taken any action on the petition. Any change in the RCRA exemption for such wastes could result in an increase in costs to manage and dispose of wastes, which could have a material adverse effect on the cash distributions to the trust unitholders. In the course of its operations, SandRidge generates petroleum hydrocarbon wastes and ordinary industrial wastes that are subject to regulation under the RCRA. SandRidge is in substantial compliance with all regulations regarding the handling and disposal of oil and gas exploration and production wastes from its operations, including with respect to the Underlying Properties.

        SandRidge currently owns or leases, and in the past may have owned or leased, properties that have been used to explore for and produce oil and natural gas. Although SandRidge may have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons and wastes may have been disposed of or released on or under the properties owned or leased by SandRidge or on or under the other locations where these hydrocarbons and wastes have been taken for treatment or disposal. In addition, certain of these properties have been operated by third parties whose treatment and disposal or release of hydrocarbons and wastes was not under SandRidge's control. These properties and wastes disposed thereon may be subject to CERCLA, RCRA and analogous state laws. Under these laws, SandRidge could be required to remove or remediate previously disposed wastes, to clean up contaminated property and to perform remedial operations to prevent future contamination or to pay some or all of the costs of any such action.

        Air Emissions.    The Clean Air Act, as amended, and comparable state laws and regulations restrict the emission of air pollutants from many sources and also impose various monitoring and reporting requirements. These laws and regulations may require SandRidge to obtain pre-approval for the

77


Table of Contents

construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and strictly comply with air permit requirements or utilize specific equipment or technologies to control emissions. Obtaining permits has the potential to delay the development of oil and natural gas projects. While SandRidge may be required to incur certain capital expenditures for air pollution control equipment or other air emissions-related issues, SandRidge does not believe that such requirements will have a material adverse effect on its ability to satisfy its obligations to the trust. In July 2011, the EPA proposed a range of new regulations that would establish new air emission controls for oil and natural gas production and natural gas processing, including, among other things, a new source performance standard for volatile organic compounds that would apply to hydraulically fractured wells, compressors, pneumatic controllers, condensate and crude oil storage tanks, and natural gas processing plants. The EPA is under a court order to finalize these proposed regulations by April 3, 2012.

        Water Discharges.    The Federal Water Pollution Control Act, as amended ("Clean Water Act"), and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants into navigable waters. Pursuant to the Clean Water Act and analogous state laws, permits must be obtained to discharge produced waters and sand, drilling fluids, drill cuttings and other substances related to the oil and gas industry into onshore, coastal and offshore waters of the United States or state waters. Any such discharge of pollutants into regulated waters must be performed in accordance with the terms of the permit issued by EPA or the analogous state agency. Spill prevention, control and countermeasure requirements under federal law require appropriate containment berms and similar structures to help prevent the contamination of navigable waters in the event of a petroleum hydrocarbon tank spill, rupture or leak. In addition, the Clean Water Act and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from certain types of facilities.

        Climate Change.    In December 2009, the EPA published its findings that emissions of carbon dioxide, methane and certain other GHGs present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth's atmosphere and other climatic changes. These findings allow the EPA to adopt and implement regulations that restrict emissions of GHGs under existing provisions of the federal Clean Air Act. Accordingly, the EPA has adopted regulations that require a reduction in emissions of GHGs from motor vehicles and also trigger Clean Air Act construction and operating permit review for GHG emissions from certain large stationary sources. The EPA's rules relating to emissions of GHGs from large stationary sources of emissions are currently subject to a number of legal challenges, but the federal courts have thus far declined to issue any injunctions to prevent the EPA from implementing, or requiring state environmental agencies to implement, the rules. In addition, in October 2009, the EPA published a final rule requiring the reporting of GHG emissions from specified large GHG emission sources in the United States, including sources emitting more than 25,000 tons of GHGs on an annual basis, beginning in 2011 for emissions occurring in 2010. In November 2010, the EPA published a final rule that expands its October 2009 final rule on reporting of GHG emissions to require certain owners and operators of onshore oil and natural gas production to monitor greenhouse gas emissions beginning in 2011 and to report those emissions beginning in 2012. The adoption and implementation of any regulations imposing reporting obligations on, or limiting emissions of GHG gases from, SandRidge's equipment and operations could require SandRidge to incur additional costs to reduce emissions of GHGs associated with its operations or could adversely affect demand for the oil and natural gas it produces. Finally, some scientists have concluded that increasing concentrations of GHGs in the Earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, and floods and other climatic events; if any such effects were to occur, they could have an adverse effect on SandRidge's assets and operations.

        In addition, Congress has considered legislation to reduce emissions of GHGs and almost one-half of the states have begun taking actions to control and/or reduce emissions of GHGs, primarily through the planned development of GHG emission inventories and/or regional GHG cap and trade programs. Any future federal laws or implementing regulations that may be adopted to address GHG emissions could

require SandRidge to incur increased operating costs, could adversely affect demand for the oil and natural gas that it produces, and could have a material adverse effect on SandRidge's business, financial condition and results of operations.

        Endangered Species.    The federal Endangered Species Act ("ESA") restricts activities that may affect endangered or threatened species or their habitats. We believe operations are in substantial compliance with the ESA. If endangered species are located in areas of the underlying properties where SandRidge wishes to conduct seismic surveys, development activities or abandonment operations, the work could be prohibited or delayed or expensive mitigation may be required. Moreover, as a result of a settlement approved by the U.S. District Court for the District of Columbia on September 9, 2011, the U.S. Fish and Wildlife Service is required to consider listing more than 250 species as endangered under the ESA. Under the September 9, 2011 settlement, the federal agency is required to make a determination on listing of the species as endangered or threatened over the next six years, through the agency's 2017 fiscal year. The designation of previously unprotected species as threatened or endangered in areas where underlying property operations are conducted could cause SandRidge to incur increased costs arising from species protection measures or could result in limitations on its exploration and production activities that could have an adverse impact on its ability to develop and produce reserves.

        Employee Health and Safety.    The operations of SandRidge are subject to a number of federal and state laws and regulations, including the federal Occupational Safety and Health Act, as amended ("OSHA"), and comparable state statutes, whose purpose is to protect the health and safety of workers. In addition, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in SandRidge's operations and that this information be provided to employees, state and local government authorities and citizens. SandRidge believes that it is in substantial compliance with all applicable laws and regulations relating to worker health and safety.

        State Regulation.    Both Oklahoma and Kansas regulate the drilling for, and the production and gathering of, oil and natural gas, including requirements relating to drilling permits, the location, spacing and density of wells, unitization and pooling of interests, the method of drilling, casing and equipping of wells, the protection of fresh water sources, the orderly development of common sources of supply of oil and natural gas, the operation of wells, allowable rates of production, the use of fresh water in oil and natural gas operations, saltwater injection and disposal operations, the plugging and abandonment of wells and the restoration of surface properties, the prevention of waste of oil and natural gas resources, the protection of the correlative rights of oil and natural gas owners and, where necessary to avoid unfair, unjust or discriminatory service, the fees, terms and conditions for the gathering of natural gas. The effect of these regulations may be to limit the number of wells that SandRidge may drill, impact the locations at which SandRidge may drill wells, restrict the amounts of oil and natural gas that may be produced from SandRidge's wells and increase the costs of its operations. Realized prices for the first sale of oil and natural gas are not subject to state regulation in Oklahoma or Kansas.

        Hydraulic Fracturing.    Oil and natural gas may be recovered from the Underlying Properties through the use of hydraulic fracturing, combined with sophisticated drilling. Hydraulic fracturing, which involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate production, is typically regulated by state oil and gas commissions. However, the EPA recently asserted federal regulatory authority over certain hydraulic fracturing practices not currently employed by SandRidge in the AMI. Also, legislation has been introduced, but not enacted, in Congress to provide for federal regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. In addition, some states have adopted, and other states, including Kansas, are considering adopting, regulations that could restrict hydraulic fracturing in certain circumstances. If new laws or regulations that significantly restrict hydraulic fracturing are adopted at the state level, such legal requirements could cause project delays and make it more difficult or costly for SandRidge to perform fracturing to stimulate production from the Mississippian formation. These delays or additional costs could

79


Table of Contents

adversely affect the determination of whether a well is commercially viable. In addition, if hydraulic fracturing is regulated at the federal level, SandRidge's fracturing activities, including with respect to its operations at the Underlying Properties, could become subject to additional permit requirements or operational restrictions and also to associated permitting delays and potential increases in costs. Restrictions on hydraulic fracturing could also reduce the amount of oil and natural gas that SandRidge is ultimately able to produce in commercial quantities from the Underlying Properties.

        In addition, a number of federal agencies are analyzing, or have been requested to review, a variety of environmental issues associated with hydraulic fracturing. The White House Council on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices, and a committee of the United States House of Representatives has conducted an investigation of hydraulic fracturing practices. The EPA has commenced a study of the potential environmental effects of hydraulic fracturing on drinking water and groundwater, with initial results expected to be available by late 2012 and final results by 2014. Moreover, the EPA announced on October 20, 2011 that it is also launching a study regarding wastewater resulting from hydraulic fracturing activities and currently plans to propose standards by 2014 that such wastewater must meet before being transported to a treatment plant. In addition, the U.S. Department of Energy is conducting an investigation of practices the agency could recommend to better protect the environment from drilling using hydraulic fracturing completion methods. Also, the U.S. Department of the Interior is considering disclosure requirements or other mandates for hydraulic fracturing on federal lands. Additionally, certain members of Congress have called upon the U.S. Government Accountability Office to investigate how hydraulic fracturing might adversely affect water resources; the SEC to investigate the natural gas industry and any possible misleading of investors or the public regarding the economic feasibility of pursuing natural gas deposits in shales by means of hydraulic fracturing; and the U.S. Energy Information Administration to provide a better understanding of that agency's estimates regarding natural gas reserves, including reserves from shale formations, as well as uncertainties associated with those estimates. These ongoing or proposed studies, depending on their degree of pursuit and any meaningful results obtained, could spur initiatives to further regulate hydraulic fracturing under the federal Safe Drinking Water Act or other regulatory mechanisms.

        All of the acreage and undeveloped reserves within the AMI are subject to hydraulic fracturing procedures as the process is required to economically develop the Mississippian formation in northern Oklahoma and southern Kansas. The hydraulic fracturing process is integral to SandRidge's overall drilling and completion costs in the AMI and represents approximately 15% of the total drilling/completion costs per well (or, approximately $450,000 per well).

        SandRidge diligently reviews best practices and industry standards, and complies with all regulatory requirements in the protection of potable water sources. Protective practices include, but are not limited to, setting multiple strings of protection pipe across the potable water sources and cementing these pipes from setting depth to surface, continuously monitoring the hydraulic fracturing process in real time, and disposing of all non-commercially produced fluids in certified disposal wells at depths below the potable water sources.

        Based on current completion techniques, a typical fracturing procedure for a well in the Mississippian formation uses approximately 1,680,000 gallons of fluid and approximately 35,000 gallons-equivalent of sand. Fresh water and/or produced saltwater make up approximately 99.8% of the total fracturing fluid. Of the remaining .2% of fluid, approximately one third is comprised of material such as enzymes and Guar (a common food additive), and slightly more than two thirds is a combination of other chemicals. In total, approximately 1,715,000 gallons of water, sand and chemicals are pumped during the typical Mississippian fracture treatment.

        There have not been any incidents, citations or suits related to SandRidge's hydraulic fracturing activities involving environmental concerns.

DESCRIPTION OF THE ROYALTY INTERESTS

        The royalty interests will be conveyed to the trust by SandRidge by means of conveyance instruments that will be recorded in the real property records in Noble, Kay, Alfalfa, Grant and Woods counties in northern Oklahoma and Harper, Comanche, Sumner and Barber counties in southern Kansas and, if necessary, the real property records of any additional counties where the oil and natural gas to which the Underlying Properties relate are located.

        The royalty interests will be conveyed from SandRidge's interest in the Producing Wells and the Development Wells. The PDP Royalty Interest entitles the trust to receive 80% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of oil and natural gas attributable to SandRidge's net revenue interest in the Producing Wells. The Development Royalty Interest entitles the trust to receive 70% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of production of oil and natural gas attributable to SandRidge's net revenue interest in the Development Wells.

        The percentage of production proceeds to be received by the trust with respect to a well will equal the product of (1) the percentage of proceeds to which the trust is entitled under the terms of the conveyances (80% for the Producing Wells and 70% for the Development Wells) multiplied by (2) SandRidge's net revenue interest in the well. SandRidge on average owns a 53.6% net revenue interest in the Producing Wells. Therefore, the trust will have an average 42.9% net revenue interest in the Producing Wells. SandRidge on average owns a 47.4% net revenue interest in the properties in the AMI on which it intends to drill the Development Wells and based on this net revenue interest, the trust would have an average 33.2% net revenue interest in the Development Wells. SandRidge's actual net revenue interest in any particular Development Well may differ from this average, and will depend on SandRidge's working interest and the royalty interests and similar revenue burdens owed to third parties with respect to such well.

PDP Royalty Interest

        The PDP Royalty Interest entitles the trust to receive an amount of cash for each calendar quarter equal to 80% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Producing Wells. Proceeds from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Producing Wells in any calendar quarter means, for any calendar quarter commencing on or after January 1, 2012, the amount calculated based on actual production volumes attributable to SandRidge's net revenue interest in the Producing Wells, in each case after deducting the trust's proportionate share of:

        Proceeds payable to the trust from the sale of oil and natural gas production attributable to the Producing Wells in any calendar quarter will not be subject to any deductions for any expenses attributable to exploration, drilling, development, operating, maintenance or any other costs incident to the production of oil and natural gas production attributable to the Producing Wells, including any costs to plug and abandon a Producing Well.

81


Table of Contents

Development Royalty Interest

        The Development Royalty Interest entitles the trust to receive an amount of cash for each calendar quarter equal to 70% of the proceeds (exclusive of any production or development costs but after deducting post-production costs and any applicable taxes) from the sale of estimated oil and natural gas production attributable to SandRidge's net revenue interest in the Development Wells. Proceeds from the sale of oil and natural gas production attributable to SandRidge's net revenue interest in the Development Wells in any calendar quarter means, for any calendar quarter commencing on or after January 1, 2012, the amount calculated based on actual production volumes attributable to SandRidge's net revenue interest in the Development Wells, in each case after deducting the trust's proportionate share of:

        Proceeds payable to the trust from the sale of oil and natural gas production attributable to the Development Wells in any calendar quarter will not be subject to any deductions for any expenses attributable to exploration, drilling, development, operating, maintenance or any other costs incident to the production of oil and natural gas production attributable to the Development Wells, including any costs to drill a Development Well.

        The Perpetual Development Royalty in respect of the Development Wells located in Kansas will have a term of 21 years commencing on January 1, 2012 and, if production commences during such period, so long thereafter as SandRidge's leasehold interests remain in force.

Sale of the Perpetual Royalties

        The trust will begin to liquidate on the Termination Date and will soon thereafter wind up its affairs and terminate. The Term Royalties will automatically revert to SandRidge at the Termination Date, while the Perpetual Royalties will be sold and the proceeds thereof will be distributed to the unitholders at the Termination Date or soon thereafter. SandRidge will have a first right of refusal to purchase the Perpetual Royalties at the Termination Date.

        The trust agreement provides that the trustee will use commercially reasonable efforts to retain a third-party advisor to market the Perpetual Royalties within 30 business days of the Termination Date. If the trustee receives a bona fide offer from a proposed purchaser other than SandRidge and wants to sell all or part of the Perpetual Royalties, it will be required to give notice (the "Offer Notice") to SandRidge, identifying the proposed purchaser and setting forth the proposed sale price, payment terms and other material terms and conditions under which the trustee is proposing to sell. SandRidge would then have 30 days from receipt of the Offer Notice to elect, by notice to the trustee, to purchase the subject properties offered for sale on the terms and conditions set forth in the Offer Notice. If SandRidge makes such election, the proposed purchaser would be entitled to receive reimbursement of its reasonable and documented expenses incurred in connection with its review and analysis of the subject properties and bid preparation. SandRidge and the trust would share equally the cost of reimbursement to the proposed purchaser.

        If SandRidge does not give notice within the 30-day period following the Offer Notice, the trustee may, within 60 days, sell such properties to the identified purchaser on terms and conditions that are substantially the same as those previously set forth in such Offer Notice. Moreover, if, after a reasonable marketing period, no bid is received on any or all of the Perpetual Royalties from any party other than

82


Table of Contents

SandRidge, then SandRidge shall obtain, at the trust's expense, and deliver to the trustee, a fairness opinion from a nationally-recognized valuation firm with expertise in valuing oil and natural gas properties stating that the proposed sale price to be paid by SandRidge to the trust for the properties is fair to the trust.

Additional Features of the Royalty Interests

        Reasonably Prudent Operator Standard.    Under the conveyances, SandRidge is obligated to act in good faith and as a reasonably prudent operator in the AMI under the same or similar circumstances as it would if it were acting with respect to its own properties, disregarding the existence of the royalty interests as burdens affecting such properties. Accordingly, there may be situations where SandRidge will drill on one or more potential drilling locations within the AMI that are not those identified locations underlying the reserve report.

        Warranty and Remedies.    In the conveyances, SandRidge will warrant to the trust that the royalty interests granted to the trust are free of all encumbrances created by, through or under SandRidge (other than certain permitted encumbrances). If this warranty is breached, SandRidge must add to amounts owed to the trust the difference between what the trust actually receives from the royalty interests and what the trust should have received from the royalty interests had this warranty not been breached. If SandRidge's net revenue interest with respect to the Underlying Properties ever proves to be larger as of the effective date of a conveyance than the amount reflected in the conveyance at the time of grant, and, as a result, the trust receives amounts greater than what the trust would have received if the correct net revenue interest had been reflected in the conveyance, SandRidge will have the right to treat any such amounts paid to the trust as a credit or offset against any amounts payable to the trust on account of a breach of the warranty described above.

        Controversies.    If a controversy arises as to the sales price of any production, then for purposes of determining gross proceeds:

        Overpayments.    The trustee is not obligated to return any cash received from the royalty interests. Any overpayments made to the trust by SandRidge due to adjustments to prior calculations of proceeds or otherwise will reduce future amounts payable to the trust until SandRidge recovers the overpayments.

        Sale and Release of Underlying Properties.    The conveyances provide that SandRidge may not sell any of the Underlying Properties subject to the royalty interests until it has satisfied the drilling obligation pursuant to the terms of the development agreement. After the satisfaction of its drilling obligation, the conveyances generally permit SandRidge to sell, without the consent or approval of the trust unitholders, all or any part of its retained interest in the Underlying Properties, if such Underlying Properties are sold subject to and burdened by the royalty interests. The trust unitholders are not entitled to any proceeds of any sale of SandRidge's interest in the Underlying Properties that remains subject to and burdened by the royalty interests. Following such sale, the royalties attributable to the transferred property will be calculated as described in this prospectus, and paid by the purchaser or transferee to the trust. As a result, any additional costs resulting from the sold property will not reduce the proceeds paid to the trust from the Underlying Properties retained by SandRidge. SandRidge will require any purchaser of any of the

83


Table of Contents

Underlying Properties to enter into an agreement to perform SandRidge's obligations under the administrative services agreement with respect to those properties under the same terms and conditions.

        In addition, following the satisfaction of its drilling obligation, SandRidge may, without the consent of the trust unitholders, require the trust to release for sale royalty interests with an aggregate value to the trust not to exceed $5.0 million during any 12-month period. These releases will be made only in connection with a sale by SandRidge of a portion of the Underlying Properties and are conditioned upon the trust receiving an amount equal to the fair value to the trust of such royalty interests. Any net sales proceeds paid to the trust in respect of any such released Underlying Properties are distributable to trust unitholders for the quarter in which they are received. SandRidge has not identified for sale any of the Underlying Properties.

        Exchange and Addition of Acreage.    SandRidge may at its option at any time prior to the completion of its drilling obligation cause the trust to exchange leased acreage subject to the royalty interests, free and clear of such royalty interests, for other leased acreage in the AMI or the Development Area, and cause such leased acreage exchanged to the trust to be made subject to the royalty interests as set forth in the conveyances (excluding any wells that are already producing on such leased acreage at the time of such exchange). Following such an exchange, any exchange acreage in the Development Area will be included in the AMI for all purposes of the development agreement, and the corresponding acreage in the AMI exchanged therewith will be excluded from the AMI for all purposes of the development agreement. In addition, in the event SandRidge acquires any additional leases or interests in the AMI (other than renewals or extensions) prior to the completion of its drilling obligation, SandRidge may at its option make such additional leases or interests subject to the royalty interests with respect to any Development Wells subsequently drilled on such acreage. In no event, however, may any exchange of acreage or any addition of leased acreage or interests be effected unless SandRidge certifies to the trust that, among other things, all of the aggregate acreage attributable to the exchanged leases or additional leases or interests does not exceed five percent of the acreage initially subject to the royalty interests and that, with respect to exchange acreage, the reasonable quantity of proved undeveloped reserves and probable reserves of such exchange acreage does not differ significantly from the reasonable quantity of proved undeveloped reserves and probable reserves being exchanged for such acreage, and, with respect to additional leases or interests, the reserve profile of such acreage is consistent with the reserve profile of the acreage that would be developed in the absence of such additional acreage.

        Abandonment of Underlying Property.    SandRidge or any transferee of an Underlying Property will have the right to abandon, at its cost, any well or property if it reasonably believes the well or property ceases to produce or is not capable of producing in commercially paying quantities. In making such decisions, SandRidge or any transferee of an Underlying Property is required under the applicable conveyance to act as a reasonably prudent operator in the AMI under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the royalty interests as burdens affecting such properties. Upon termination of the lease, that portion of the royalty interests derived from the terminated lease will be extinguished.

        Maintenance of Books and Records.    SandRidge must maintain books and records sufficient to determine the amounts payable for the royalty interests to the trust. Quarterly and annually, SandRidge must deliver to the trustee a statement of the computation of the proceeds for each computation period as well as quarterly drilling and production results. Because SandRidge files reports with the SEC, those reports will be publicly available. See "Where You Can Find More Information."

        Reservation of Rights.    Pursuant to the conveyances, SandRidge will expressly except and reserve all right, title and interest in and to any well and appurtenant production facilities not expressly conveyed to the trust.

DESCRIPTION OF THE TRUST AGREEMENT

Creation and Organization of the Trust; Amendments

        The trust was created under Delaware law as a separate legal entity to acquire and hold the royalty interests for the benefit of the trust unitholders pursuant to an agreement between SandRidge, the trustee and the Delaware trustee. The royalty interests are passive in nature and neither the trust nor the trustee has any control over or responsibility for costs relating to the operation of the Underlying Properties. Neither SandRidge nor any other operator of the Underlying Properties has any contractual commitments to the trust to provide additional funding or to conduct further drilling on or to maintain its ownership interest in any of these properties other than the obligations of SandRidge to designate and drill the Development Wells. After the conveyance of the royalty interests, however, SandRidge will retain an interest in each of the Underlying Properties. For a description of the Underlying Properties and other information relating to them, see "The Underlying Properties."

        The trust agreement will provide that the trust's business activities will generally be limited to owning the royalty interests and entering into hedging arrangements and other activities reasonably related thereto, including activities required or permitted by the terms of the conveyances related to the royalty interests. As a result, the trust will not be permitted to acquire other oil and natural gas properties or royalty interests. Additionally, following the completion of this offering, the trust will not be able to issue any additional trust units.

        The beneficial interests in the trust are divided into 48,250,000 trust units. Each trust unit represents an equal undivided beneficial interest in the property of the trust. Please read "Description of the Trust Units" for additional information concerning the trust units.

        Amendment of the trust agreement generally requires the vote of holders of a majority of the trust units and a majority of the common units (excluding common units owned by SandRidge and its affiliates) voting in person or by proxy at a meeting of such unitholders at which a quorum is present. At any time that SandRidge and its affiliates collectively own less than 10% of the total trust units outstanding, however, the standard for approval will be the vote of a majority of the trust units, including units owned by SandRidge, voting in person or by proxy at a meeting of the unitholders at which a quorum is present. Abstentions and broker non-votes shall not be deemed to be a vote cast. However, no amendment may:

        Amendments to the trust agreement's provisions addressing the following matters may not be made without SandRidge's consent:

        Certain amendments to the trust agreement do not require the vote of the trust unitholders. See "—Permitted Amendments."

85


Table of Contents

        The business and affairs of the trust will be managed by the trustee. The trustee will have no ability to manage or influence the operations of the Underlying Properties. SandRidge operates 79% of the Producing Wells and expects to operate approximately 67% of the Development Wells during the subordination period but will have no ability to manage or influence the management of the trust, except through its limited voting rights as a holder of trust units and its limited ability to manage the hedging program.

Assets of the Trust

        Upon completion of this offering, the principal assets of the trust will consist of the PDP Royalty Interest, the Development Royalty Interest and any cash and temporary investments being held for the payment of expenses and liabilities and for distribution to the trust unitholders, as well as the trust's rights under its contractual arrangements, including the development agreement, the Drilling Support Lien, the administrative services agreement, the derivatives agreement and the hedge contracts with unaffiliated hedge counterparties. See "The Trust" for more information.

Duties and Powers of the Trustee; Liability of the Trustee

        The duties and powers of the trustee are specified in the trust agreement and by the laws of the State of Delaware, except as modified by the trust agreement. The trust agreement provides that the trustee shall not have any duties or liabilities, including fiduciary duties, except as expressly set forth in the trust agreement and the duties and liabilities of the trustee as set forth in the trust agreement replace any other duties and liabilities, including fiduciary duties, to which the trustee might otherwise be subject.

        The trustee's principal duties consist of:

        SandRidge will provide administrative and other services to the trust in fulfillment of certain of the foregoing duties, pursuant to the administrative services agreement.

        If a trust liability is contingent or uncertain in amount or not yet currently due and payable, the trustee may create a cash reserve to pay for the liability. If the trustee determines that the cash on hand and the cash to be received are insufficient to cover the trust's liability, the trustee may cause the trust to borrow funds required to pay the liabilities. The trust may borrow the funds from any person, including the trustee or its affiliates or, as described below, SandRidge. The terms of such indebtedness, if funds were loaned by the entity serving as trustee or Delaware trustee, would be similar to the terms which such entity would grant to a similarly situated commercial customer with whom it did not have a fiduciary relationship, and such entity shall be entitled to enforce its rights with respect to any such indebtedness as if it were not then serving as trustee or Delaware trustee. If the trust borrows funds, the trust unitholders will not receive

86


Table of Contents

distributions until the borrowed funds are repaid (except, in certain circumstances, where the trust borrows funds from SandRidge). For information regarding SandRidge's obligation to loan funds to the trust in certain limited circumstances, see "—SandRidge Obligation to Fund Trust Expenses in Certain Circumstances" below.

        Each quarter, the trustee will pay trust obligations and expenses and distribute to the trust unitholders the remaining proceeds received from the royalty interests and hedging arrangements. The cash held by the trustee as a reserve against future liabilities must be invested in:

        Alternatively, cash held for distribution at the next distribution date may be held in a non-interest bearing account.

        The trustee intends to withhold $1.0 million from the first distribution to unitholders to establish a cash reserve available to the trustee to pay trust administrative expenses. If the trustee uses such cash reserve (or any portion thereof) to pay or reimburse trust liabilities or expenses, no further distributions will be made to unitholders (except in respect of any previously determined quarterly cash distribution amount) until the cash reserve is replenished. This cash reserve will be part of the trust estate and will bear interest at the same rate as other cash on hand in the trust estate. Upon the dissolution of the trust, the balance of the cash reserve (including accrued interest thereon) will be distributed to trust unitholders on a pro rata basis.

        The trust may not acquire any asset except the royalty interests, the other assets described above under "—Assets of the Trust" and cash and temporary cash investments, and it may not engage in any investment activity except investing cash on hand. The trust may also enter into replacement hedges, or modify its hedging arrangements, in certain circumstances.

        The trust agreement provides that the trustee will not make business decisions affecting the assets of the trust. However, the trustee may:

        In discharging its duty to trust unitholders, the trustee may act in its discretion and will be liable to the trust unitholders only for willful misconduct, bad faith or gross negligence. The trustee will not be liable for any act or omission of its agents or employees unless the trustee acted with willful misconduct, bad faith or gross negligence in its selection and retention. The trustee will be indemnified individually or as the trustee for any liability or cost that it incurs in the administration of the trust, except in cases of willful misconduct, bad faith or gross negligence. The trustee will have a lien on the assets of the trust as security for this indemnification and its compensation earned as trustee. Trust unitholders will not be liable to the trustee for any indemnification. See "Description of the Trust Units—Liability of Trust Unitholders." The trustee will ensure that all contractual liabilities of the trust are limited to the assets of the trust.

87


Table of Contents

Merger or Consolidation of Trust

        The trust may merge or consolidate with or into, or convert into, one or more limited partnerships, general partnerships, corporations, business trusts, limited liability companies, or associations or unincorporated businesses if such transaction is agreed to by the trustee and approved by the vote of the holders of a majority of the trust units and a majority of the common units (excluding common units owned by SandRidge and its affiliates) in each case voting in person or by proxy at a meeting of such holders at which a quorum is present and such transaction is permitted under the Delaware Statutory Trust Act and any other applicable law. At any time that SandRidge and its affiliates collectively own less than 10% of the total trust units outstanding, however, the standard for approval will be the vote of a majority of the trust units, including units owned by SandRidge voting in person or by proxy at a meeting of such holders at which a quorum is present.

Trustee's Power to Sell Royalty Interests

        The trustee may sell the royalty interests under any of the following circumstances:

        Upon dissolution of the trust the trustee must sell the royalty interests. No trust unitholder approval is required in this event. See "—Duration of the Trust; Sale of Royalty Interests" below.

        The trustee will distribute the net proceeds from any sale of the royalty interests and other assets to the trust unitholders after payment or reasonable provision for payment of the liabilities of the trust.

Permitted Amendments

        The trustee may amend or supplement the trust agreement, the conveyances, the development agreement, the administrative services agreement, the derivatives agreement, the hedge contracts, the registration rights agreement or the Drilling Support Lien, without the approval of the trust unitholders, to cure ambiguities, to correct or supplement defective or inconsistent provisions, to grant any benefit to all trust unitholders, to add collateral to the Drilling Support Lien, to evidence or implement any changes required by applicable law or to change the name of the trust, provided, however, that any such supplement or amendment does not adversely affect the interests of the trust unitholders. Furthermore, the trustee, acting alone, may amend the administrative services agreement without the approval of trust unitholders if such amendment would not increase the cost or expense of the trust or create an adverse economic impact on the trust unitholders. Finally, modifications of the hedging arrangements entered into by the trust will not require the approval of the trust unitholders.

        All other permitted amendments to the trust agreement and other agreements listed above may only be made by the vote of a majority of the trust units and a majority of the common units (excluding common units owned by SandRidge and its affiliates) in each case voting in person or by proxy at a meeting of such holders at which a quorum is present; except that at any time that SandRidge and its affiliates collectively own less than 10% of the total trust units outstanding, the standard for approval will be the vote of a majority of the trust units, including units owned by SandRidge voting in person or by proxy at a meeting

of such holders at which a quorum is present. Abstentions and broker non-votes shall not be deemed to be a vote cast.

Liabilities of the Trust; Fees and Expenses

        The trust will be a party to oil hedging arrangements and could have payment obligations under such arrangements. Otherwise, the trust does not conduct an active business and the trustee has little power to incur obligations. As a result, it is expected that the trust will only incur liabilities for routine administrative expenses, such as legal, accounting, tax advisory, engineering, printing and other administrative and out-of-pocket fees and expenses incurred by or at the direction of the trustee or the Delaware trustee, including tax return and Schedule K-1 preparation and mailing costs; independent auditor fees; and registrar and transfer agent fees. The trust will also be responsible for paying costs associated with annual and quarterly reports to unitholders. Moreover, the trustee's and the Delaware trustee's compensation, and the fee payable to SandRidge pursuant to the administrative services agreement will be paid out of the trust's assets. See "The Trust" for more information on these costs.

SandRidge Obligation to Fund Trust Expenses in Certain Circumstances

        SandRidge has agreed that, if at any time the trust's cash on hand (including available cash reserves) is not sufficient to pay the trust's ordinary course administrative expenses as they become due, SandRidge will loan funds to the trust necessary to pay such expenses. Any funds loaned by SandRidge pursuant to this commitment will be limited to the payment of current accounts payable or other obligations to trade creditors in connection with obtaining goods or services or the payment of other accrued current liabilities arising in the ordinary course of the trust's business, and may not be used to satisfy trust indebtedness. If SandRidge loans funds pursuant to this commitment, unless SandRidge agrees otherwise, no further distributions will be made to unitholders (except in respect of any previously determined quarterly cash distribution amount) until such loan is repaid. Any such loan will be on an unsecured basis, and the terms of such loan will be substantially the same as those which would be obtained in an arms' length transaction between SandRidge and an unaffiliated third party.

Duration of the Trust; Sale of Royalty Interests

        The trust will not dissolve until the Termination Date, which is December 31, 2031, unless:

        In the case of any of the foregoing, the trustee would sell all of the trust's assets, either by private sale or public auction, and distribute the net proceeds of the sale to the trust unitholders after payment, or reasonable provision for payment, of all trust liabilities.

Dispute Resolution

        To the fullest extent permitted by law, any dispute, controversy or claim that may arise between SandRidge and the trustee relating to the trust will be submitted to binding arbitration before a panel of three arbitrators.

Tax Matters

        Trust unitholders will be treated as partners of the trust for U.S. federal income tax purposes. The trust agreement contains tax provisions that generally allocate the trust's income, gain, loss, deduction and credit among the trust unitholders in accordance with their percentage interests in the trust. The trust agreement also sets forth the tax accounting principles to be applied by the trust.

Miscellaneous

        The trustee may consult with counsel (which may include counsel to SandRidge), accountants, tax advisors, geologists and engineers and other parties the trustee believes to be qualified as experts on the matters for which advice is sought. The trustee will be protected for any action it takes in good faith reliance upon the opinion of the expert.

        The Delaware trustee and the trustee may resign at any time or be removed with or without cause at any time by the vote of a majority of the common units (excluding common units owned by SandRidge and its affiliates) voting in person or by proxy at a meeting of such holders at which a quorum is present; except that at any time that SandRidge and its affiliates collectively own less than 10% of the total trust units outstanding, the standard for approval will be the vote of a majority of the trust units, including units owned by SandRidge, voting in person or by proxy at a meeting of such holders at which a quorum is present. Abstentions and broker non-votes shall not be deemed to be a vote cast. Any successor must be a bank or trust company meeting certain requirements including having combined capital, surplus and undivided profits of at least $20 million, in the case of the Delaware trustee, and $100 million, in the case of the trustee.

        The principal offices of the trust are located at 919 Congress Avenue, Suite 500, Austin, Texas 78701, and its telephone number is (512) 236-6599.

DESCRIPTION OF THE TRUST UNITS

        Each trust unit is a unit of the beneficial interest in the trust and is entitled to receive cash distributions from the trust on a pro rata basis. Each trust unitholder has the same rights regarding each of his trust units as every other trust unitholder has regarding his units. The trust will have 48,250,000 trust units outstanding upon completion of the offering, consisting of 36,187,500 common units and 12,062,500 subordinated units.

Common Units; Subordinated Units

        The trust units will initially be comprised of both common units and subordinated units. The common units and subordinated units will have identical rights and privileges, except with respect to their voting rights and rights to receive distributions. For a discussion of unitholders' voting rights, see "—Voting Rights of Trust Unitholders" below.

        The subordinated units will be entitled to receive pro rata distributions from the trust each quarter if and to the extent there is sufficient cash to provide a cash distribution on the common units that is no less than the applicable quarterly subordination threshold. If there is not sufficient cash to fund such a distribution on all of the common units, the distribution to be made with respect to the subordinated units will be reduced or eliminated for such quarter in order to make a distribution, to the extent possible, of up to the subordination threshold amount on all the common units, including the common units held by SandRidge. For more information, see "Target Distributions and Subordination and Incentive Thresholds."

        The subordinated units will automatically convert into common units on a one-for-one basis at the end of the fourth full calendar quarter following SandRidge's satisfaction of its drilling obligation with respect to the Development Wells.

Distributions; Income Computations

        Cash distributions to trust unitholders will be made by the trust from its available funds for each calendar quarter. Royalty interest payments due to the trust with respect to any calendar quarter will be based on actual production volumes attributable to the trust properties for the first two months of the quarter just ended as well as the last month of the immediately preceding quarter (as measured at SandRidge metering systems) and actual revenues received for such volumes. During the term of the derivatives agreement, SandRidge will determine the amounts due to (or from) the trust under the derivatives agreement. SandRidge will make a payment to the trust equal to the sum of the royalty interest payments and amounts due the trust under the derivatives agreement within 45 days of the end of each calendar quarter. In addition, any payment due from or required to be made to the counterparties under the trust's direct hedge contracts or SandRidge under the derivatives agreement will be paid by the 45th day following the end of such calendar quarter. After the receipt and disbursement of all such amounts, the trustee will determine for such calendar quarter the amount of funds available for distribution to the trust unitholders. Available funds are the excess cash, if any, received by the trust over the trust's expenses for that quarter. Available funds will be reduced by any cash the trustee decides to hold as a reserve against future liabilities.

        The amount of available funds for distribution each quarter will be payable to the trust unitholders of record on or about the 45th day following the end of such calendar quarter or such later date as the trustee determines is required to comply with legal or stock exchange requirements. The trustee will distribute cash on or about the 60th day (or the next succeeding business day following such day if such day is not a business day) following such calendar quarter to each person who was a trust unitholder of record on the quarterly record date, together with interest expected to be earned on the amount of such quarterly distribution from the date of receipt thereof by the trustee to the payment date.

91


Table of Contents

        Unless otherwise advised by counsel or the IRS, the trustee will treat the income and expenses of the trust for each quarter as belonging to the trust unitholders of record on the quarterly record date that occurs in such quarter. Trust unitholders will recognize income and expenses for tax purposes in the quarter the trust receives or pays those amounts, rather than in the quarter the trust distributes them. Minor variances may occur. For example, the trustee could establish a reserve in one quarter that would not result in a tax deduction until a later quarter. The trustee could also make a payment in one month that would be amortized for tax purposes over several quarters. See "U.S. Federal Income Tax Considerations."

Transfer of Trust Units

        Trust unitholders may transfer their trust units in accordance with the trust agreement. The trustee will not require either the transferor or transferee to pay a service charge for any transfer of a trust unit. The trustee may require payment of any tax or other governmental charge imposed for a transfer. The trustee may treat the owner of any trust unit as shown by its records as the owner of the trust unit. The trustee will not be considered to know about any claim or demand on a trust unit by any party except the record owner. A person who acquires a trust unit after any quarterly record date will not be entitled to the distribution relating to that quarterly record date. Delaware law will govern all matters affecting the title, ownership or transfer of trust units.

Tax Schedules and Periodic Reports

        The trustee will file all required trust federal and state income tax and information returns. The trustee will prepare and mail to trust unitholders a Schedule K-1 that trust unitholders need to correctly report their share of the income and deductions of the trust. The trustee will also cause to be prepared and filed reports required to be filed under the Securities Exchange Act of 1934, as amended, and by the rules of any securities exchange or quotation system on which the trust units are listed or admitted to trading.

        Each trust unitholder and his representatives may examine, for any proper purpose, during reasonable business hours the records of the trust and the trustee.

Liability of Trust Unitholders

        Under the Delaware Statutory Trust Act, trust unitholders will be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit under the General Corporation Law of the State of Delaware. No assurance can be given, however, that the courts in jurisdictions outside of Delaware will give effect to such limitation.

Voting Rights of Trust Unitholders

        The trustee or trust unitholders owning at least 10% of the total trust units outstanding may call meetings of trust unitholders. The trust will be responsible for all costs associated with calling a meeting of trust unitholders unless such meeting is called by the trust unitholders, in which case the trust unitholders will be responsible for all costs associated with calling such meeting of trust unitholders. Meetings must be held in such location as is designated by the trustee in the notice of such meeting. The trustee must send notice of the time and place of the meeting and the matters to be acted upon to all of the trust unitholders at least 20 days and not more than 60 days before the meeting. Trust unitholders representing a majority of trust units outstanding must be present or represented to have a quorum. Each trust unitholder is entitled to one vote for each trust unit owned. Abstentions and broker non-votes shall not be deemed to be a vote cast.

        Unless otherwise required by the trust agreement, a matter may be approved or disapproved by the vote of a majority of the trust units held by the trust unitholders voting in person or by proxy at a meeting

where there is a quorum. This is true, even if a majority of the total trust units outstanding did not approve it.

        Until such time as SandRidge and its affiliates own less than 10% of the total trust units outstanding, the vote of the holders of a majority of common units (excluding common units owned by SandRidge and its Affiliates) and a majority of trust units voting in person or by proxy at a meeting of such holders at which a quorum is present is required to:

        In addition, until such time as SandRidge and its affiliates own less than 10% of the total trust units outstanding, the vote of the holders of a majority of common units (excluding common units owned by SandRidge and its affiliates) voting in person or by proxy at a meeting of such holders at which a quorum is present is required to remove the trustee and to appoint a successor trustee.

        At any time when SandRidge and its affiliates own less than 10% of the total trust units outstanding, the vote of the holders of a majority of trust units, including units owned by SandRidge voting in person or by proxy at a meeting of such holders at which a quorum is present will be required to take the actions described above.

        Certain amendments to the trust agreement may be made by the trustee without approval of the trust unitholders. The trustee must consent before all or any part of the trust assets can be sold except in connection with the dissolution of the trust or limited sales directed by SandRidge in conjunction with its sale of Underlying Properties.

Comparison of Trust Units and Common Stock

        Trust unitholders have more limited voting rights than those of stockholders of most public corporations. For example, there is no requirement for annual meetings of trust unitholders or for annual or other periodic re-election of the trustee.

93


Table of Contents

        Unitholders should also be aware of the following ways in which an investment in trust units is different from an investment in common stock of a corporation.

 
  Trust units   Common stock
Voting   The trust agreement provides voting rights to trust unitholders to remove and replace (but not elect) the trustee and to approve or disapprove major trust transactions.   Unless otherwise provided in the certificate of incorporation, corporate statutes provide voting rights to stockholders of the corporation to elect directors and to approve or disapprove amendments to the certificate of incorporation and certain major corporate transactions.

Income Tax

 

The trust is not subject to U.S. federal income tax. Trust unitholders are subject to income tax on their allocable share of trust income, gain, loss and deduction.

 

Corporations are subject to U.S. federal income tax. Their stockholders are taxed on dividends.

Distributions

 

All trust revenue is distributed to trust unitholders after payment of trust expenses and additions, if any, to trust reserves.

 

Unless otherwise provided in the certificate of incorporation, stockholders are entitled to receive dividends solely at the discretion of the board of directors.

Business and Assets

 

The business of the trust is limited to specific assets with a finite economic life.

 

Unless otherwise provided in the certificate of incorporation, a corporation conducts an active business for an unlimited term and can reinvest its earnings and raise additional capital to expand.

Fiduciary Duties

 

To the extent provided in the trust agreement, the trustee has limited its fiduciary duties in the trust agreement as permitted by the Delaware Statutory Trust Act so that it will be liable to unitholders only for willful misconduct, bad faith or gross negligence.

 

Officers and directors have a fiduciary duty of loyalty to the corporation and the stockholders and a duty to exercise due care in the management and administration of a corporation's affairs.

TRUST UNITS ELIGIBLE FOR FUTURE SALE

General

        Prior to this offering, there has been no public market for the common units. Sales of substantial amounts of the common units in the open market, or the perception that those sales could occur, could adversely affect prevailing market prices.

        Upon completion of this offering, there will be 48,250,000 trust units outstanding. All of the 25,000,000 common units sold in this offering, or the 28,750,000 common units if the underwriters exercise their over-allotment option in full, will be freely tradable without restriction under the Securities Act. All of the 23,250,000 trust units to be held by SandRidge (19,500,000 trust units if the underwriters exercise their over-allotment in full) following completion of the offering will be "restricted securities" within the meaning of Rule 144 under the Securities Act and may not be sold other than through registration under the Securities Act or pursuant to an exemption from registration, subject to the restrictions on transfer contained in the lock-up agreements described below and in "Underwriters." SandRidge expects to pledge all of the units it owns after completion of the offering as collateral under its credit facility.

SandRidge Lock-up Agreement

        In connection with this offering, SandRidge has agreed, for a period of 180 days after the date of this prospectus, not to offer, sell, contract to sell or otherwise dispose of or transfer any trust units or any securities convertible into or exchangeable for trust units, without the prior written consent of Morgan Stanley & Co. LLC and Raymond James & Associates, Inc., acting as representatives of the several underwriters. See "Underwriters" for a description of this lock-up agreement. Upon the expiration of this lock-up agreement, all of the units held by SandRidge will be eligible for sale in the public market under Rule 144 of the Securities Act, subject to volume limitations and other restrictions contained in Rule 144, or through registration under the Securities Act.

Rule 144

        The common units sold in the offering will generally be freely transferable without restriction or further registration under the Securities Act, except that any common units owned by an "affiliate" of SandRidge or the trust may not be resold publicly except in compliance with the registration requirements of the Securities Act or under an exemption under Rule 144 or otherwise. Rule 144 permits securities acquired by an affiliate to be sold into the market in an amount that does not exceed, during any three-month period, the greater of:

        Sales under Rule 144 are also subject to specific manner of sale provisions, holding period requirements, notice requirements and the availability of current public information about the trust. A person who is not deemed to have been an affiliate of SandRidge or the trust at any time during the three months preceding a sale, and who has beneficially owned common units for at least six months (provided the trust is in compliance with the current public information requirement) or one year (regardless of whether the trust is in compliance with the current public information requirement), would be entitled to sell common units under Rule 144 without regard to the rule's public information requirements, volume limitations, manner of sale provisions and notice requirements.

Registration Rights Agreement

        The trust intends to enter into a registration rights agreement for the benefit of SandRidge and certain of its affiliates and transferees (each, a "holder"). In the registration rights agreement, the trust will agree, for the benefit of each holder, to register the trust units held by such holder. Specifically, the trust will agree:

        The holders will have the right to require the trust to file no more than five registration statements in aggregate.

        In connection with the preparation and filing of any registration statement, SandRidge will bear all costs and expenses incidental to any registration statement, excluding certain internal expenses of the trust, which will be borne by the trustee, and any underwriting discounts and commissions, which will be borne by the seller of the trust units.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

        This section is a discussion of the material tax considerations that may be relevant to prospective trust unitholders who are individual citizens or residents of the United States and, unless otherwise noted in the following discussion, is the opinion of Covington & Burling LLP, counsel to SandRidge and the trust, insofar as it relates to legal conclusions with respect to matters of U.S. federal income tax law. This section is based upon current provisions of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), existing and proposed Treasury regulations promulgated under the Internal Revenue Code (the "Treasury Regulations") and current administrative rulings and court decisions, all of which are subject to change. Future changes in these authorities may cause the tax consequences to vary substantially from the consequences described below.

        The following discussion does not address all U.S. federal income tax matters affecting the trust or the trust unitholders. Moreover, the discussion focuses on trust unitholders who are individual citizens or residents of the United States and has only limited application to corporations, estates, trusts, nonresident aliens or other unitholders subject to specialized tax treatment, such as tax-exempt institutions, non-U.S. persons, taxpayers subject to the alternative minimum tax, individual retirement accounts (IRAs), employee benefit plans, real estate investment trusts (REITs) or mutual funds. Accordingly, the trust encourages each prospective trust unitholder to consult, and depend on, his own tax advisor in analyzing the federal, state, local and foreign tax consequences particular to him of the ownership or disposition of trust units.

        No ruling has been or will be requested from the Internal Revenue Service (the "IRS") regarding any matter affecting the trust or prospective trust unitholders. Instead, the trust will rely on opinions of counsel. Unlike a ruling, an opinion of counsel represents only that counsel's best legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS. Any contest of this sort with the IRS may materially and adversely impact the market for the trust units and the prices at which trust units trade. In addition, the costs of any contest with the IRS, principally legal, accounting and related fees, will result in a reduction in cash available for distribution to the trust unitholders, and thus will be borne indirectly by the trust unitholders. Furthermore, the tax treatment of the trust, or of an investment in the trust, may be significantly modified by future legislative or administrative changes or court decisions. Any modifications may or may not be retroactively applied.

        All statements as to matters of law and legal conclusions, but not as to factual matters, contained in this section, unless otherwise noted, are the opinion of Covington & Burling LLP and are based on the accuracy of the representations made by SandRidge and the trust.

        For the reasons described below, Covington & Burling LLP has not rendered an opinion with respect to the following specific U.S. federal income tax issues: (1) the treatment of a trust unitholder whose trust units are loaned to a short seller to cover a short sale of trust units (please read "—Tax Consequences of Trust Unit Ownership—Treatment of Short Sales"); (2) whether the trust's convention for allocating taxable income and losses is permitted by existing Treasury Regulations (please read "—Disposition of Trust Units—Allocations Between Transferors and Transferees"); and (3) whether percentage depletion will be available to a trust unitholder or the extent of the percentage depletion deduction available to any trust unitholder (please read "—Tax Consequences of Trust Unit Ownership—Tax Treatment of the Perpetual Royalties").

        As used herein, the term "trust unitholder" means a beneficial owner of trust units that for U.S. federal income tax purposes is:

97


Table of Contents

        The term "non-U.S. trust unitholder" means any beneficial owner of a trust unit (other than an entity that is classified for U.S. federal income tax purposes as a partnership or as a "disregarded entity") that is not a trust unitholder.

        If an entity that is classified for U.S. federal income tax purposes as a partnership is a beneficial owner of trust units, the tax treatment of a member of the entity will depend upon the status of the member and the activities of the entity. The trust encourages any entity that is classified for U.S. federal income tax purposes as a partnership and that is a beneficial owner of trust units, and the members of such an entity, to consult their own tax advisors about the U.S. federal income tax considerations of purchasing, owning, and disposing of trust units.

Classification of the Trust as a Partnership

        Although the trust is formed as a statutory trust under Delaware law, the trust's classification for U.S. federal income tax purposes is based on its characteristics rather than its form. Based on such characteristics, it is expected that, as described below, the trust will be treated for federal and applicable state income tax purposes as a partnership and trust unitholders will be treated as partners in that partnership.

        A partnership is not a taxable entity and incurs no U.S. federal income tax liability. Instead, each partner of a partnership is required to take into account his share of items of income, gain, loss, deduction and credit of the partnership in computing his federal income tax liability, regardless of whether cash distributions are made to him by the partnership. Distributions by a partnership to a partner are generally not taxable to the partner unless the amount of cash distributed to him is in excess of the partner's adjusted basis in his partnership interest as of the end of the taxable year in which the distribution is made.

        Section 7704 of the Internal Revenue Code provides that publicly traded partnerships will, as a general rule, be taxed as corporations. However, an exception, referred to in this discussion as the "Qualifying Income Exception," exists with respect to publicly traded partnerships of which 90% or more of the gross income for every taxable year consists of "qualifying income." Qualifying income includes income and gains derived from the exploration, development, production and marketing of oil and natural gas and interest income (other than from a financial business). Other types of qualifying income include gains from the sale of real property and income from certain hedging transactions. The trust anticipates that substantially all of its gross income will be qualifying income. Based upon the factual representations made by the trust and SandRidge and a review of the applicable legal authorities, Covington & Burling LLP is of the opinion that at least 90% of the trust's gross income will constitute qualifying income.

        No ruling has been or will be sought from the IRS and the IRS has made no determination as to the trust's status for federal income tax purposes or whether the trust's operations generate "qualifying income" under Section 7704 of the Internal Revenue Code. Instead, the trust will rely on the opinion of Covington & Burling LLP on such matters. It is the opinion of Covington & Burling LLP that, based upon the Internal Revenue Code, Treasury Regulations, published revenue rulings and court decisions and the representations described below, the trust will be classified as a partnership for federal income tax purposes.

98


Table of Contents

        In rendering its opinion, Covington & Burling LLP has relied on factual representations made by the trust and SandRidge. The representations made by the trust and SandRidge upon which Covington & Burling LLP has relied are:

        The trust believes that these representations are true and expects that these representations will continue to be true in the future.

        If the trust fails to meet the Qualifying Income Exception, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery (in which case the IRS may also require the trust to make adjustments with respect to the trust's unitholders allocable share of trust income, gain, loss or deduction or pay other amounts), the trust will be treated as if it had transferred all of its assets, subject to liabilities, to a newly formed corporation, on the first day of the year in which the trust fails to meet the Qualifying Income Exception, in return for stock in that corporation, and then distributed that stock to the unitholders in liquidation of their interests in the trust. This deemed contribution and liquidation should be tax-free to the trust unitholders and the trust. Thereafter, the trust would be treated as an association taxable as a corporation for federal income tax purposes.

        If the trust were treated as an association taxable as a corporation in any taxable year, either as a result of a failure to meet the Qualifying Income Exception or otherwise, the trust's items of income, gain, loss and deduction would be reflected only on the trust's tax return rather than being passed through to the trust unitholders, and the trust's net income would be taxed to the trust at corporate rates. In addition, any distribution made to a trust unitholder would be treated as either taxable dividend income, to the extent of the trust's current or accumulated earnings and profits, or, in the absence of earnings and profits, a nontaxable return of capital, to the extent of the trust unitholder's tax basis in his trust units, or taxable capital gain, after the trust unitholder's tax basis in his trust units is reduced to zero. Accordingly, taxation as a corporation would result in a material reduction in a trust unitholder's cash flow and after-tax return and thus would likely result in a substantial reduction of the value of the trust units.

        The discussion below is based on Covington & Burling LLP's opinion that the trust will be classified as a partnership for U.S. federal income tax purposes.

Partner Status

        Trust unitholders will be treated as partners of the trust for U.S. federal income tax purposes. Also, trust unitholders whose trust units are held in street name or by a nominee and who have the right to direct the nominee in the exercise of all substantive rights attendant to the ownership of their trust units will be treated as partners of the trust for U.S. federal income tax purposes.

        A beneficial owner of trust units whose trust units have been transferred to a short seller to complete a short sale would appear, as a result, to lose his status as a partner with respect to those trust units for U.S. federal income tax purposes. Please read "—Tax Consequences of Trust Unit Ownership—Treatment

Table of Contents

of Short Sales." Income, gain, deductions or losses would not appear to be reportable by a trust unitholder who is not a partner for federal income tax purposes, and any cash distributions received by a trust unitholder who is not a partner for federal income tax purposes would therefore appear to be fully taxable as ordinary income. These unitholders are urged to consult their own tax advisors with respect to their tax considerations related to holding trust units. The references to "unitholders" in the discussion that follows are to persons who are treated as partners in the trust for federal income tax purposes.

Tax Classification of the PDP Royalty Interest and the Development Royalty Interest

        For U.S. federal income tax purposes, the Perpetual PDP Royalty and the Perpetual Development Royalty will have the tax characteristics of mineral royalty interests to the extent they are, at the time of their creation, reasonably expected to have an economic life that corresponds substantially to the economic life of the mineral property or properties burdened thereby. Payments out of production that are received in respect of a mineral interest that constitutes a royalty interest for U.S. federal income tax purposes are taxable under current law as ordinary income subject to an allowance for cost or percentage depletion in respect of such income.

        In contrast, the Term PDP Royalty and the Term Development Royalty will have the tax characteristics of production payments governed by Section 636 of the Internal Revenue Code to the extent they may not, at the time of their creation, be reasonably expected to extend in substantial amounts over the entire productive lives of the mineral property or properties they burden. Payments out of production that are received in respect of a mineral interest that constitutes a production payment for U.S. federal income tax purposes are treated under current law as consisting of a receipt of principal and interest on a nonrecourse debt obligation, with the interest component being taxable as ordinary income.

        In the event that a portion of a single royalty interest terminates by its terms prior to the point in time that the economically productive life of the burdened mineral property is substantially exhausted and the remaining portion continues to burden the property until its economically productive life is substantially exhausted, the federal income tax characteristics of the royalty interest are determined as if it comprised two separate interests, with the terminating portion being treated as a production payment and the continuing portion being treated as a royalty interest.

        Based on the reserve report and representations made by SandRidge regarding the expected economic life of the Underlying Properties and the expected duration of the Term Royalties and the Perpetual Royalties, the Term PDP Royalty will and the Term Development Royalty should be treated as "production payments" under Section 636 of the Internal Revenue Code, and thus as nonrecourse debt instruments of SandRidge for U.S. federal income tax purposes. The Perpetual PDP Royalty will, and the Perpetual Development Royalty should, be treated as continuing, nonoperating economic interests in the nature of royalties payable out of production from the mineral interests they burden.

        The difference in certainty between the treatment of the Term PDP Royalty and the Perpetual PDP Royalty, on the one hand, and the Term Development Royalty and the Perpetual Development Royalty, on the other hand, stems from the fact that while the Term PDP Royalty and Perpetual PDP Royalty are interests in the Producing Wells (developed wells that have been drilled), the Term Development Royalty and Perpetual Development Royalty are interests in the Development Wells (undeveloped wells that will be drilled in the future). The applicable laws are well developed, and directly applicable precedents exist, with regard to the tax treatment of royalty interests in specified developed wells that have been drilled. Although such laws and precedents are applicable in analyzing the tax treatment of royalty interests in proven reserves and undeveloped wells related thereto that will be drilled in the future, the law is less well developed in this area. As a result, the tax treatment of the Term Development Royalty and the Perpetual Development Royalty are not entirely free from doubt. Therefore, the difference in certainty between the treatment of the PDP Royalties and the Development Royalties set forth in the preceding paragraph and elsewhere in this prospectus reflects the difference in certainty between developed and undeveloped wells.

Table of Contents

        Consistent with the foregoing, SandRidge and the trust intend to treat the Perpetual Royalties as mineral royalty interests for U.S. federal income tax purposes. In addition, SandRidge and the trust intend to treat the Term Royalties as debt instruments for U.S. federal income tax purposes subject to the Treasury Regulations applicable to contingent payment debt instruments (the "CPDI regulations"), and the trust will agree to be bound by SandRidge's application of the CPDI regulations, including SandRidge's determination of the rate at which interest will be deemed to accrue on such interests. The remainder of this discussion assumes that the Term Royalties will be treated in accordance with that agreement and SandRidge's determinations and that the Perpetual Royalties will be treated as mineral royalty interests. No assurance can be given that the IRS will not assert that such interests should be treated differently. Such different treatment could affect the amount, timing and character of income, gain or loss in respect of an investment in trust units and could require a trust unitholder to accrue interest income at a rate different than the "comparable yield" described below. Please read "—Tax Consequences of Trust Unit Ownership—Tax Treatment of the Term Royalties," and "—Tax Consequences of Trust Unit Ownership—Tax Treatment of the Perpetual Royalties."

Tax Consequences of Trust Unit Ownership

        Flow-Through of Taxable Income.    As a partnership for U.S. federal income tax purposes, the trust will not be a taxable entity required to pay any federal income tax. Instead, each trust unitholder will be required to report on his income tax return his allocable share of the trust's income, gains, losses, deductions and credits without regard to whether the trust makes cash distributions to him. Consequently, the trust may allocate taxable income to a trust unitholder even if he has not received a cash distribution.

        Accounting Method and Taxable Year.    The trust will use the year ending December 31 as its taxable year and the accrual method of accounting for U.S. federal income tax purposes. Each trust unitholder will be required to include in income his share of the trust's income, gain, loss, deduction and credit for the trust's taxable year ending within or with his taxable year. In addition, a trust unitholder who has a taxable year ending on a date other than December 31 and who disposes of all of his trust units following the close of the trust's taxable year but before the close of his taxable year must include his share of the trust's income, gain, loss, deduction and credit in his taxable income for his taxable year, with the result that he will be required to include in income for his taxable year his share of more than 12 months of the trust's income, gain, loss, deduction and credit. Please read "—Disposition of Trust Units—Allocations Between Transferors and Transferees."

        A trust unitholder's initial tax basis for his trust units will be the amount he paid for the trust units. That basis will be increased by his share of the trust's income and gain and decreased, but not below zero, by distributions from the trust, by the trust unitholder's share of the trust's losses, if any, by depletion deductions taken by him to the extent such deductions do not exceed his proportionate allocated share of the adjusted tax basis of the Perpetual Royalties, and by his share of the trust's expenditures that are not deductible in computing taxable income and are not required to be capitalized. Please read "—Disposition of Trust Units—Recognition of Gain or Loss."

        Allocation of Income, Gain, Loss, Deduction and Credit.    In general, if the trust has a net profit, the trust's items of income, gain, loss, deduction and credit will be allocated among the trust unitholders in accordance with their percentage interests in the trust. At any time that distributions are made to the common units in excess of distributions to the subordinated trust units, or SandRidge receives incentive distributions, gross income will be allocated to the recipients to the extent of these distributions. If the trust has a net loss, that loss will be allocated first to the subordinated trust units to the extent of their positive capital accounts and thereafter to the trust unitholders in accordance with their percentage interests in the trust.

        Specified items of the trust's income, gain, loss, deduction and credit will be allocated under Section 704(c) of the Internal Revenue Code to account for any difference between the tax basis and fair

101


Table of Contents

market value of any property treated as having been contributed to the trust by SandRidge or certain of its affiliates that exists at the time of such contribution, together, referred to in this discussion as the "Contributed Property." These "Section 704(c) Allocations" are required to eliminate the difference between a partner's "book" capital account, credited with the fair market value of Contributed Property, and the "tax" capital account, credited with the tax basis of Contributed Property, referred to in this discussion as the "Book-Tax Disparity." The effect of these Section 704(c) Allocations to a unitholder purchasing trust units from the trust in this offering will be essentially the same as if the tax bases of the trust's assets were equal to their fair market value at the time of this offering. Finally, although the trust does not expect that its operations will result in the creation of negative capital accounts, if negative capital accounts nevertheless result, items of the trust's income and gain will be allocated in an amount and manner sufficient to eliminate the negative balance as quickly as possible.

        An allocation of items of the trust's income, gain, loss, deduction or credit, other than an allocation required by Section 704(c) of the Internal Revenue Code to eliminate the Book-Tax Disparity, will generally be given effect for U.S. federal income tax purposes in determining a unitholder's share of an item of income, gain, loss, deduction or credit only if the allocation has substantial economic effect. In any other case, a unitholder's share of an item will be determined on the basis of his interest in the trust, which will be determined by taking into account all the facts and circumstances, including:

        Covington & Burling LLP is of the opinion that, with the exception of the issues described in "Disposition of Trust Units—Allocations Between Transferors and Transferees," allocations under the trust agreement will be given effect for U.S. federal income tax purposes in determining a unitholder's share of an item of income, gain, loss, deduction or credit.

        Treatment of Trust Distributions.    Distributions by the trust to a trust unitholder generally will not be taxable to the trust unitholder for U.S. federal income tax purposes, except to the extent the amount of any such cash distribution exceeds his tax basis in his trust units immediately before the distribution. The trust's cash distributions in excess of a unitholder's tax basis (if any) generally will be considered to be gain from the sale or exchange of the trust units, taxable in accordance with the rules described under "—Disposition of Trust Units" below.

        Ratio of Taxable Income to Distributions.    The trust estimates that a purchaser of trust units in this offering who owns those trust units from the date of closing of this offering through the record date for distributions for the period ending December 31, 2014, will be allocated, on a cumulative basis, an amount of federal taxable income for that period that will be approximately            % of the cash distributed with respect to that period. These estimates and assumptions are subject to, among other things, numerous business, economic, regulatory, legislative, competitive and political uncertainties beyond the trust's control. Further, the estimates are based on current tax law and tax reporting positions that the trust will adopt and with which the IRS could disagree. Accordingly, the trust cannot assure unitholders that these estimates will prove to be correct. The actual percentage of distributions that will correspond to taxable income could be higher or lower than expected, and any differences could be material and could materially affect the value of the trust units.

        Tax Treatment of the Term Royalties.    Under the CPDI regulations, the trust generally will be required to accrue income on the Term Royalties which are treated as production payments, and therefore as nonrecourse debt obligations of SandRidge for U.S. federal income tax purposes, in the amounts described below.

102


Table of Contents

        The CPDI regulations provide that the trust must accrue an amount of ordinary interest income for U.S. federal income tax purposes, for each accrual period prior to and including the maturity date of the debt instrument that equals:

        The "issue price" of the debt instrument represented by each production payment held by the trust is the portion of the first price at which a substantial amount of the trust units is sold to the public, excluding sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers, that is allocable to the production payment based on the relative fair market value of the production payment to the other assets of the trust. The "adjusted issue price" of such a debt instrument is its issue price increased by any interest income previously accrued, determined without regard to any adjustments to interest accruals described below, and decreased by the projected amount of any payments scheduled to be made with respect to the debt instrument at an earlier time (without regard to the actual amount paid). The term "comparable yield" means the annual yield SandRidge would be expected to pay, as of the initial issue date, on a fixed rate debt security with no contingent payments but with terms and conditions otherwise comparable to those of the debt instrument represented by the production payment.

        SandRidge will determine the comparable yield and provide this information to the trust. In addition, the CPDI regulations require that SandRidge provide to the trust, solely for determining the amount of interest accruals for U.S. federal income tax purposes, a schedule of the projected amounts of payments, which are referred to as projected payments, on the Term Royalties treated as debt instruments held by the trust. These payments set forth on the schedule must produce a total return on such debt instruments equal to their comparable yield. Amounts treated as interest under the CPDI regulations are treated as original issue discount for all purposes of the Internal Revenue Code.

        As required by the CPDI regulations, for U.S. federal income tax purposes, the trust must use the comparable yield and the schedule of projected payments as described above in determining the trust's interest accruals, and the adjustments thereto described below, in respect of the debt instruments held by the trust.

        SandRidge's determinations of the comparable yield and the projected payment schedule are not binding on the IRS and it could challenge such determinations. If it did so, and if any such challenge were successful, then the amount and timing of interest income accruals of the trust would be different from those reported by the trust or included on previously filed tax returns by the trust unitholders.

        The comparable yield and the schedule of projected payments are not determined for any purpose other than for the determination for U.S. federal income tax purposes of the trust's interest accruals and adjustments thereof in respect of the debt instruments held by the trust and do not constitute a projection or representation regarding the actual amounts payable to the trust.

        For U.S. federal income tax purposes, the trust is required under the CPDI regulations to use the comparable yield and the projected payment schedule established by SandRidge in determining interest accruals and adjustments in respect of the production payments, unless the trust timely discloses and justifies the use of a different comparable yield and projected payment schedule to the IRS. Pursuant to the terms of the conveyance, SandRidge and the trust have agreed (in the absence of an administrative determination or judicial ruling to the contrary) to be bound by SandRidge's determination of the comparable yield and projected payment schedule.

103


Table of Contents

        If, during any taxable year, the trust receives actual payments with respect to a debt instrument held by the trust that in the aggregate exceed the total amount of projected payments for that taxable year, the trust will incur a "net positive adjustment" under the CPDI regulations equal to the amount of such excess. The trust will treat a "net positive adjustment" as additional interest income for such taxable year.

        If the trust receives in a taxable year actual payments with respect to a debt instrument held by the trust that in the aggregate are less than the amount of projected payments for that taxable year, the trust will incur a "net negative adjustment" under the CPDI regulations equal to the amount of such deficit. This adjustment will (a) reduce the trust's interest income on the debt instrument held by the trust for that taxable year, and (b) to the extent of any excess after the application of (a) give rise to an ordinary loss to the extent of the trust's interest income on such debt instrument during prior taxable years, reduced to the extent such interest was offset by prior net negative adjustments. Any negative adjustment in excess of the amount described in (a) and (b) will be carried forward, as a negative adjustment to offset future interest income in respect of that debt instrument held by the trust. If either of the Term Royalties is not treated as a production payment (and not otherwise as a debt instrument) for U.S. federal income tax purposes, the trust intends to take the position that its basis in the Term Royalty is recouped in proportion to the production from the Term Royalty.

        Neither the trust nor the trust unitholders are entitled to claim depletion deductions with respect to the Term Royalties.

        Tax Treatment of the Perpetual Royalties.    The payments received by the trust in respect of the Perpetual Royalties treated as mineral royalty interests for U.S. federal income tax purposes should be treated as ordinary income. Trust unitholders should be entitled to deductions for the greater of either cost depletion or (if otherwise allowable) percentage depletion with respect to such income. Although the Internal Revenue Code requires each trust unitholder to compute his own depletion allowance and maintain records of his share of the adjusted tax basis of the underlying royalty interest for depletion and other purposes, the trust intends to furnish each of the trust unitholders with information relating to this computation for U.S. federal income tax purposes. Each trust unitholder, however, remains responsible for calculating his own depletion allowance and maintaining records of his share of the adjusted tax basis of the Perpetual Royalties for depletion and other purposes.

        Percentage depletion is generally available with respect to trust unitholders who qualify under the independent producer exemption contained in Section 613A(c) of the Internal Revenue Code. For this purpose, an independent producer is a person not directly or indirectly involved in the retail sale of oil, oil and natural gas, or derivative products or the operation of a major refinery. Percentage depletion is calculated as an amount generally equal to 15% (and, in the case of marginal production, potentially a higher percentage) of the trust unitholder's gross income from the depletable property for the taxable year. The percentage depletion deduction with respect to any property is limited to 100% of the taxable income of the trust unitholder from the property for each taxable year, computed without the depletion allowance. A trust unitholder that qualifies as an independent producer may deduct percentage depletion only to the extent the trust unitholder's average daily production of domestic oil, or the natural gas equivalent, does not exceed 1,000 barrels. This depletable amount may be allocated between oil and natural gas production, with 6,000 cubic feet of domestic oil and natural gas production regarded as equivalent to one barrel of crude oil. The 1,000-barrel limitation must be allocated among the independent producer and controlled or related persons and family members in proportion to the respective production by such persons during the period in question.

        In addition to the foregoing limitations, the percentage depletion deduction otherwise available is limited to 65% of a trust unitholder's total taxable income from all sources for the year, computed without the depletion allowance, the deduction for domestic production activities, net operating loss carrybacks, or capital loss carrybacks. Any percentage depletion deduction disallowed because of the 65% limitation may be deducted in the following taxable year if the percentage depletion deduction for such year plus the

104


Table of Contents

deduction carryover does not exceed 65% of the trust unitholder's total taxable income for that year. The carryover period resulting from the 65% net income limitation is unlimited.

        In addition to the limitations on percentage depletion discussed above, President Obama's budget proposal for the fiscal year 2012 proposes to eliminate certain tax preferences applicable to taxpayers engaged in the exploration or production of natural resources. Specifically, the budget proposes to repeal the deduction for percentage depletion with respect to wells, in which case only cost depletion would be available. It is uncertain whether this or any other legislative proposals will ever be enacted and, if so, when any such proposal would become effective.

        Trust unitholders that do not qualify under the independent producer exemption are generally restricted to depletion deductions based on cost depletion. Cost depletion deductions are calculated by (a) dividing the trust unitholder's allocated share of the adjusted tax basis in the underlying mineral property by the number of mineral units (barrels of oil and thousand cubic feet of natural gas) remaining as of the beginning of the taxable year and (b) multiplying the result by the number of mineral units sold within the taxable year. The total amount of deductions based on cost depletion cannot exceed the trust unitholder's share of the total adjusted tax basis in the property.

        The foregoing discussion of depletion deductions does not purport to be a complete analysis of the complex legislation and Treasury Regulations relating to the availability and calculation of depletion deductions by the trust unitholders. Further, because depletion is required to be computed separately by each trust unitholder and not by the trust, no assurance can be given, and counsel is unable to express any opinion, with respect to the availability or extent of percentage depletion deductions to the trust unitholders for any taxable year. The trust encourages each prospective trust unitholder to consult his tax advisor to determine whether percentage depletion would be available to him.

        Tax Treatment Upon Sale of the Perpetual Royalties at Termination Date.    The sale of the Perpetual Royalties by the trust at or shortly after the Termination Date will generally give rise to long-term capital gain or loss to the trust unitholders for U.S. federal income tax purposes, except that any gain will be taxed at ordinary income rates to the extent of depletion deductions that reduced the trust unitholder's adjusted basis in the Perpetual Royalties. Each trust unitholder will be responsible for calculating his gain or loss based on the difference between his pro-rata share of the amount realized on the sale by the trust and his adjusted basis in the Perpetual Royalties, and if a gain is realized, the portion thereof taxable as ordinary income by reason of depletion deductions previously claimed by such trust unitholder. However, the trust intends to furnish each of the trust unitholders with information relating to this calculation for U.S. federal income tax purposes in connection with the final partnership tax return for the trust.

        Tax Treatment of Hedging Income.    Income or loss realized with respect to hedging arrangements entered into by the trust will give rise to ordinary income or loss to the trust unitholders for U.S. federal income tax purposes. Trust unitholders will not be entitled to depletion deductions with respect to any hedging income.

        Limitations on Deductibility of Losses.    It is not anticipated that the trust will generate losses. Nevertheless, should losses result, trust unitholders must consult their own tax advisors as to the applicability to them of loss limitation rules that could operate to limit the deductibility to a trust unitholder of his share of the trust's losses such as the basis limitation, the "at risk" rules and the passive loss rules. Special passive loss limitation rules apply with respect to publicly-traded partnerships.

        Limitations on Interest Deductions.    The deductibility of a non-corporate taxpayer's "investment interest expense" is generally limited to the amount of that taxpayer's "net investment income." Investment interest expense includes:

105


Table of Contents

        The computation of a trust unitholder's investment interest expense will take into account interest on any margin account borrowing or other loan incurred to purchase or carry a trust unit. Net investment income includes gross income from property held for investment and amounts treated as portfolio income under the passive loss rules, less deductible expenses, other than interest, directly connected with the production of investment income, but generally does not include gains attributable to the disposition of property held for investment or qualified dividend income. The IRS has indicated that the net passive income earned by a publicly traded partnership will be treated as investment income to its unitholders for purposes of the investment interest deduction limitation. In addition, the trust unitholder's share of the trust's portfolio income will be treated as investment income.

        Entity-Level Withholdings.    If the trust is required or elects under applicable law to pay any federal, state, local or foreign income tax on behalf of any trust unitholder or any former trust unitholder, the trust is authorized to pay those taxes from its funds. That payment, if made, will be treated as a distribution of cash to the trust unitholder on whose behalf the payment was made. If the payment is made on behalf of a person whose identity cannot be determined, the trust is authorized to treat the payment as a distribution to all current trust unitholders. The trust is authorized to amend its trust agreement in the manner necessary to maintain uniformity of intrinsic tax characteristics of trust units. Payments by the trust as described above could give rise to an overpayment of tax on behalf of an individual trust unitholder in which event the trust unitholder would be required to file a claim in order to obtain a credit or refund.

        Treatment of Short Sales.    A trust unitholder whose trust units are loaned to a "short seller" to cover a short sale of trust units may be considered as having disposed of those units. If so, he would no longer be treated for tax purposes as a partner with respect to those trust units during the period of the loan and may recognize gain or loss from the disposition. As a result, during this period:

        Covington & Burling LLP has not rendered an opinion regarding the tax treatment of a trust unitholder whose trust units are loaned to a short seller to cover a short sale of trust units; therefore, trust unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing and loaning their trust units. The IRS has previously announced that it is studying issues relating to the tax treatment of short sales of partnership interests. Please also read "—Disposition of Trust Units—Recognition of Gain or Loss."

        Alternative Minimum Tax.    Each trust unitholder will be required to take into account his distributive share of any items of the trust's income, gain, loss, deduction or credit for purposes of the alternative minimum tax. The current minimum tax rate for non-corporate taxpayers is 26% on the first $175,000 of alternative minimum taxable income in excess of the exemption amount and 28% on any additional alternative minimum taxable income. Prospective trust unitholders are urged to consult with their tax advisors as to the impact of an investment in trust units on their liability for the alternative minimum tax.

        Tax Rates.    Under current law, the highest marginal U.S. federal income tax rate applicable to ordinary income of individuals is 35% and the highest marginal U.S. federal income tax rate applicable to long-term capital gains (generally, capital gains on certain assets held for more than 12 months) of individuals is 15%. However, absent new legislation extending the current rates, beginning January 1, 2013,

106


Table of Contents

the highest marginal U.S. federal income tax rate applicable to ordinary income and long-term capital gains of individuals will increase to 39.6% and 20%, respectively. Moreover, these rates are subject to change by new legislation at any time.

        The recently enacted Health Care and Education Reconciliation Act of 2010 will impose a 3.8% Medicare tax on certain investment income earned by individuals, estates and trusts for taxable years beginning after December 31, 2012. For these purposes, investment income generally includes a trust unitholder's allocable share of the trust's income and gain realized by a trust unitholder from a sale of trust units. In the case of an individual, the tax will be imposed on the lesser of (1) the trust unitholder's net income from all investments, and (2) the amount by which the trust unitholder's adjusted gross income exceeds $250,000 (if the trust unitholder is married and filing jointly or a surviving spouse), $125,000 (if the trust unitholder is married and filing separately) or $200,000 (if the trust unitholder is not married). In the case of an estate or trust, the tax will be imposed on the lesser of (1) the undistributed net investment income of the estate or trust, or (2) the excess of the adjusted gross income of the estate or trust over the dollar amount at which the highest income tax bracket applicable to an estate or trust begins.

        Section 754 Election.    The trust will make the election permitted by Section 754 of the Internal Revenue Code. That election is irrevocable without the consent of the IRS. The election will generally permit the trust to adjust a subsequent trust unit purchaser's tax basis in the trust's assets ("inside basis") under Section 743(b) of the Internal Revenue Code to reflect his purchase price of trust units acquired from another trust unitholder. The Section 743(b) adjustment belongs to the purchaser and not to other trust unitholders. For purposes of this discussion, a trust unitholder's inside basis in the trust's assets will be considered to have two components: (1) his share of tax basis in the trust's assets ("common basis") and (2) his Section 743(b) adjustment to that basis.

        A Section 754 election is advantageous if the transferee's tax basis in his units is higher than the units' share of the aggregate tax basis of the trust's assets immediately prior to the transfer. In such a case, as a result of the election, the transferee would have a higher tax basis in his share of the trust's assets for purposes of calculating, among other items, cost depletion deductions on the Perpetual Royalties, and his share of any gain on a sale of the trust's assets would be less. Conversely, a Section 754 election is disadvantageous if the transferee's tax basis in his units is lower than those trust units' share of the aggregate tax basis of the trust's assets immediately prior to the transfer. Thus, the fair market value of the trust units may be affected either favorably or unfavorably by the election. A basis adjustment is required regardless of whether a Section 754 election is made in the case of a transfer of an interest in the trust if it has a substantial built-in loss immediately after the transfer. Generally a built-in loss or a basis reduction is substantial if it exceeds $250,000.

        The calculations involved in the Section 754 election are complex and will be made on the basis of assumptions as to the value of the trust's assets and other matters. For example, the allocation of the Section 743(b) adjustment among the trust's assets must be made in accordance with the Internal Revenue Code. The trust cannot assure unitholders that the determinations it makes will not be successfully challenged by the IRS and that the deductions resulting from them will not be reduced or disallowed altogether. Should the IRS require a different basis adjustment to be made, and should, in the trust's opinion, the expense of compliance exceed the benefit of the election, the trust may seek permission from the IRS to revoke its Section 754 election. If permission is granted, a subsequent purchaser of trust units may be allocated more income than he would have been allocated had the election not been revoked.

        Initial Tax Basis and Amortization.    The initial tax basis of the portion of the PDP Royalty Interest treated as a royalty interest in minerals (the Perpetual PDP Royalty) and the portion treated as a production payment (the Term PDP Royalty), and the initial basis of the portion of the Development Royalty Interest treated as a royalty interest in minerals (the Perpetual Development Royalty) and the portion treated as a production payment (the Term Development Royalty) will be effectively equal on a

107


Table of Contents

per-unit basis to the portion of the unit price allocated to each based on each such portion's relative fair market value.

        The costs incurred in selling the trust units (called "syndication expenses") must be capitalized and cannot be deducted currently, ratably or upon the trust's termination. There are uncertainties regarding the classification of costs as organizational expenses, which may be amortized by the trust, and as syndication expenses, which may not be amortized by the trust. The underwriting discounts and commissions the trust incurs will be treated as syndication expenses.

        Valuation and Tax Basis of the Trust's Properties.    The U.S. federal income tax consequences of the ownership and disposition of trust units will depend in part on the trust's estimates of the relative fair market values, and the initial tax bases, of the trust's assets. Although the trust may from time to time consult with professional appraisers regarding valuation matters, the trust will make many of the relative fair market value estimates itself. These estimates and determinations of basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss or deductions previously reported by trust unitholders might change, and trust unitholders might be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.

Disposition of Trust Units

        Recognition of Gain or Loss.    Gain or loss will be recognized on a sale of trust units equal to the difference between the amount realized and the trust unitholder's tax basis for the trust units sold. A trust unitholder's amount realized will be measured by the sum of the cash or the fair market value of other property received. The amount realized should be reduced by the unused net negative adjustments attributable to the trust units disposed of as described above under "—Tax Consequences of Trust Unit Ownership—Tax Treatment of the Term Royalties." A trust unitholder's adjusted tax basis in his trust units will be equal to the trust unitholder's original purchase price for the trust units, increased by income and decreased by losses or deductions previously allocated to the trust unitholder and by distributions to the trust unitholder and depletion deductions claimed by the trust unitholder.

        Prior distributions from the trust in excess of cumulative net taxable income for a trust unit that decreased a unitholder's tax basis in that trust unit will, in effect, become taxable income if the trust unit is sold at a price greater than the trust unitholder's tax basis in that trust unit, even if the price received is less than his original cost.

        Except as noted below, gain or loss recognized by a trust unitholder, other than a "dealer" in trust units, on the sale or exchange of a trust unit will generally be taxable as capital gain or loss. Capital gain recognized by an individual on the sale of trust units held for more than 12 months will generally be taxed at a maximum U.S. federal income tax rate of 15% through December 31, 2012 and 20% thereafter (absent new legislation extending or adjusting the current rate). However, a portion, which will likely be substantial, of this gain or loss will be separately computed and taxed as ordinary income or loss under Section 751 of the Internal Revenue Code to the extent attributable to assets giving rise to "unrealized receivables" the trust owns. The term "unrealized receivables" includes potential recapture items, including depletion recapture. Ordinary income attributable to unrealized receivables such as depletion recapture may exceed net taxable gain realized upon the sale of a trust unit and may be recognized even if there is a net taxable loss realized on the sale of a trust unit. Thus, a trust unitholder may recognize both ordinary income and a capital loss upon a sale of trust units. Net capital losses may offset capital gains and no more than $3,000 of ordinary income, in the case of individuals, and may only be used to offset capital gains in the case of corporations.

        The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all those interests. Upon a sale or other disposition of less than all of those interests, a portion of that tax basis must be allocated to the interests

108


Table of Contents

sold using an "equitable apportionment" method, which generally means that the tax basis allocated to the interest sold equals an amount that bears the same relation to the partner's tax basis in his entire interest in the partnership as the value of the interest sold bears to the value of the partner's entire interest in the partnership. Treasury Regulations under Section 1223 of the Internal Revenue Code allow a selling trust unitholder who can identify trust units transferred with an ascertainable holding period to elect to use the actual holding period of the trust units transferred. Thus, according to the ruling discussed above, a trust unitholder will be unable to select high or low basis trust units to sell as would be the case with corporate stock, but, according to the Treasury Regulations, he may designate specific trust units sold for purposes of determining the holding period of trust units transferred. A trust unitholder electing to use the actual holding period of trust units transferred must consistently use that identification method for all subsequent sales or exchanges of trust units. A trust unitholder considering the purchase of additional trust units or a sale of trust units purchased in separate transactions is urged to consult his tax advisor as to the possible consequences of this ruling and application of the Treasury Regulations.

        Specific provisions of the Internal Revenue Code affect the taxation of some financial products and securities, including partnership interests, by treating a taxpayer as having sold an "appreciated" partnership interest, one in which gain would be recognized if it were sold, assigned or terminated at its fair market value, if the taxpayer or related persons enter(s) into:

        Moreover, if a taxpayer has previously entered into a short sale, an offsetting notional principal contract or a futures or forward contract with respect to the partnership interest, the taxpayer will be treated as having sold that position if the taxpayer or a related person then acquires the partnership interest or substantially identical property. The Secretary of the Treasury is also authorized to issue regulations that treat a taxpayer that enters into transactions or positions that have substantially the same effect as the preceding transactions as having constructively sold the financial position.

        Allocations Between Transferors and Transferees.    In general, the trust's taxable income and losses will be determined and allocated on a quarterly basis and apportioned among the trust unitholders in proportion to the number of trust units of record owned by each of them as of the opening of the applicable exchange on which the trust units are then traded on the quarterly record date occurring in such quarter, which is referred to in this prospectus as the "Allocation Date."

        Although simplifying conventions are contemplated by the Internal Revenue Code, the use of this method may not be permitted under existing Treasury Regulations. Accordingly, Covington & Burling LLP is unable to opine on the validity of this method of allocating income and deductions between transferor and transferee trust unitholders. If this method is not allowed under the Treasury Regulations, or only applies to transfers of less than all of the trust unitholder's interest, the trust's taxable income or losses might be reallocated among the trust unitholders. The trust is authorized to revise its method of allocation between transferor and transferee trust unitholders, as well as trust unitholders whose interests vary during a taxable year, to conform to a method permitted under future Treasury Regulations.

        Notification Requirements.    A trust unitholder who sells any of his trust units is generally required to notify the trust in writing of that sale within 30 days after the sale (or, if earlier, January 15 of the year following the sale). A purchaser of trust units who purchases trust units from another trust unitholder is also generally required to notify the trust in writing of that purchase within 30 days after the purchase. Upon receiving such notifications, the trust is required to notify the IRS of that transaction and to furnish specified information to the transferor and transferee. Failure to notify the trust of a purchase may, in some cases, lead to the imposition of penalties. However, these reporting requirements do not apply to a

109

sale by an individual who is a citizen of the United States and who affects the sale or exchange through a broker who will satisfy such requirements.

        Constructive Termination.    The trust will be considered to have been terminated for tax purposes if there are sales or exchanges which, in the aggregate, constitute 50% or more of the total interests in the trust's capital and profits within a twelve-month period. For purposes of measuring whether the 50% threshold is reached, multiple sales of the same interest are counted only once. A constructive termination results in the closing of the trust's taxable year for all trust unitholders. In the case of a trust unitholder reporting on a taxable year other than a calendar year, the closing of the trust's taxable year may result in more than 12 months of the trust's taxable income or loss being includable in his taxable income for the year of termination. A constructive termination occurring on a date other than December 31 will result in the trust filing two tax returns (and trust unitholders may receive two Schedule K-1's) for one fiscal year and the cost of the preparation of these returns will be borne by all trust unitholders. The trust would be required to make new tax elections after a termination, including a new election under Section 754 of the Internal Revenue Code. A termination could also result in penalties if the trust was unable to determine that the termination had occurred. Moreover, a termination might either accelerate the application of, or subject the trust to, any tax legislation enacted before the termination.

Tax-Exempt Organizations and Certain Other Investors

        Ownership of trust units by employee benefit plans, other tax-exempt organizations, non-resident aliens, non-U.S. corporations and other non-U.S. persons raises issues unique to those investors and, as described below, may have substantially adverse tax consequences to them. If a potential investor is a tax-exempt entity or a non-U.S. person, then it should consult a tax advisor before investing in the trust units.

        Tax-Exempt Organizations.    Employee benefit plans and most other organizations exempt from U.S. federal income tax including IRAs and other retirement plans are subject to U.S. federal income tax on unrelated business taxable income. Because all of the income of the trust is expected to be royalty income, interest income, hedging income and gain from the sale of real property, none of which is unrelated business taxable income, any such organization exempt from U.S. federal income tax is not expected to be taxable on income generated by ownership of trust units so long as neither the property held by the trust nor the trust units are debt-financed property within the meaning of Section 514(b) of the Internal Revenue Code. In general, trust property would be debt-financed if the trust incurs debt to acquire the property or otherwise incurs or maintains a debt that would not have been incurred or maintained if the property had not been acquired and a trust unit would be debt-financed if the trust unitholder incurs debt to acquire the trust unit or otherwise incurs or maintains a debt that would not have been incurred or maintained if the trust unit had not been acquired.

        Non-U.S. Persons.    The trust (or the appropriate intermediary if units are held in "Street Name") intends to withhold on distributions paid to non-U.S. trust unitholders. The trust currently intends to withhold at the highest applicable effective tax rate. Non-U.S. trust unitholders should consult their own tax advisors with respect to seeking a credit or refund for any portion of taxes withheld from distributions.

        As long as the trust units are regularly traded on an established securities market, gain realized by a non-U.S. trust unitholder on a sale of trust units will not be subject to U.S. federal income tax unless:

Administrative Matters

        Trust Information Returns and Audit Procedures.    The trust intends to furnish to each trust unitholder, within 90 days after the close of each calendar year, specific tax information, including a Schedule K-1, which describes his share of the trust's income, gain, loss and deduction for the trust's preceding taxable year. In preparing this information, which will not be reviewed by counsel, the trust will take various accounting and reporting positions, some of which have been mentioned earlier, to determine each trust unitholder's share of income, gain, loss and deduction. The trust cannot assure unitholders that those positions will yield a result that conforms to the requirements of the Internal Revenue Code, Treasury Regulations or administrative interpretations of the IRS. Neither the trust nor Covington & Burling LLP can assure prospective trust unitholders that the IRS will not successfully contend in court that those positions are impermissible. Any challenge by the IRS could negatively affect the value of the units.

        The IRS may audit the trust's U.S. federal income tax information returns. Adjustments resulting from an IRS audit may require each trust unitholder to adjust a prior year's tax liability, and possibly may result in an audit of his return. Any audit of a trust unitholder's return could result in adjustments not related to the trust's returns as well as those related to the trust's returns.

        Partnerships generally are treated as separate entities for purposes of federal tax audits, judicial review of administrative adjustments by the IRS and tax settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined in a partnership proceeding rather than in separate proceedings with the partners. The Internal Revenue Code requires that one partner be designated as the "Tax Matters Partner" for these purposes. The trust agreement names SandRidge as the trust's Tax Matters Partner.

        The Tax Matters Partner has made and will make some elections on behalf of the trust and the trust unitholders. In addition, the Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against trust unitholders for items in the trust's returns. The Tax Matters Partner may bind a trust unitholder with less than a 1% profits interest in the trust to a settlement with the IRS unless that trust unitholder elects, by filing a statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the trust unitholders are bound, of a final partnership administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any trust unitholder having at least a 1% interest in profits or by any group of trust unitholders having in the aggregate at least a 5% interest in profits. However, only one action for judicial review will go forward, and each trust unitholder with an interest in the outcome may participate.

        A trust unitholder must file a statement with the IRS identifying the treatment of any item on his federal income tax return that is not consistent with the treatment of the item on the trust's return. Intentional or negligent disregard of this consistency requirement may subject a trust unitholder to substantial penalties.

        Nominee Reporting.    Persons who hold an interest in the trust as a nominee for another person are required to furnish to the trust:

111


Table of Contents

        Brokers and financial institutions are required to furnish additional information, including whether they are United States persons and specific information on units they acquire, hold or transfer for their own account. A penalty of $100 per failure, up to a maximum of $1,500,000 per calendar year, is imposed by the Internal Revenue Code for failure to report that information to the trust. The nominee is required to supply the beneficial owner of the trust units with the information furnished to the trust.

        Accuracy-Related Penalties.    An additional tax equal to 20% of the amount of any portion of an underpayment of tax that is attributable to one or more specified causes, including negligence or disregard of rules or regulations, substantial understatements of income tax and substantial valuation misstatements, is imposed by the Internal Revenue Code. No penalty will be imposed, however, for any portion of an underpayment if it is shown that there was a reasonable cause for that portion and that the taxpayer acted in good faith regarding that portion.

        For individuals, a substantial understatement of income tax in any taxable year exists if the amount of the understatement exceeds the greater of 10% of the tax required to be shown on the return for the taxable year or $5,000. The amount of any understatement subject to penalty generally is reduced if any portion is attributable to a position adopted on the return:

        If any item of income, gain, loss or deduction included in the distributive shares of trust unitholders might result in that kind of an "understatement" of income for which no "substantial authority" exists, the trust must disclose the pertinent facts on its return. In addition, the trust will make a reasonable effort to furnish sufficient information for trust unitholders to make adequate disclosure on their returns and to take other actions as may be appropriate to permit trust unitholders to avoid liability for this penalty. More stringent rules apply to "tax shelters," which the trust does not believe includes it, or any of the trust's investments, plans or arrangements.

        A substantial valuation misstatement exists if (a) the value of any property, or the tax basis of any property, claimed on a tax return is 150% or more of the amount determined to be the correct amount of the valuation or tax basis, (b) the price for any property or services (or for the use of property) claimed on any such return with respect to any transaction between persons described in Internal Revenue Code Section 482 is 200% or more (or 50% or less) of the amount determined under Section 482 to be the correct amount of such price, or (c) the net Internal Revenue Code Section 482 transfer price adjustment for the taxable year exceeds the lesser of $5 million or 10% of the taxpayer's gross receipts.

        No penalty is imposed unless the portion of the underpayment attributable to a substantial valuation misstatement exceeds $5,000 ($10,000 for most corporations). The penalty is increased to 40% in the event of a gross valuation misstatement. The trust does not anticipate making any valuation misstatements.

        Reportable Transactions.    If the trust were to engage in a "reportable transaction," the trust (and possibly the unitholders) would be required to make a detailed disclosure of the transaction to the IRS. A transaction may be a reportable transaction based upon any of several factors, including the fact that it is a

112


Table of Contents

type of tax avoidance transaction publicly identified by the IRS as a "listed transaction" or that it produces certain kinds of losses for partnerships, individuals, S corporations, and trusts in excess of $2 million in any single year, or $4 million in any combination of 6 successive tax years. The trust's participation in a reportable transaction could increase the likelihood that the trust's U.S. federal income tax information return (and possibly the unitholders' tax return) would be audited by the IRS. Please read "—Trust Information Returns and Audit Procedures."

        Moreover, if the trust were to participate in a reportable transaction with a significant purpose to avoid or evade tax, or in any listed transaction, unitholders may be subject to the following provisions of the American Jobs Creation Act of 2004:

The trust does not expect to engage in any "reportable transactions."

STATE TAX CONSIDERATIONS

        The following is intended as a brief summary of certain information regarding state income taxes. No opinion of counsel has been requested or received with respect to the state tax consequences of an investment in trust units. Trust unitholders are urged to consult their own legal and tax advisors with respect to these matters.

        Prospective investors should consider state and local income tax consequences of an investment in the common units. The trust will own royalty interests burdening specified oil and natural gas properties located in Noble, Kay, Alfalfa, Grant and Woods counties in northern Oklahoma and Harper, Comanche, Sumner and Barber counties in southern Kansas.

        Oklahoma Income Taxes.    If the trust is treated as a partnership for U.S. federal income tax purposes, it will also be treated as a partnership for Oklahoma income tax purposes. Trust unitholders will be subject to Oklahoma income tax on all trust royalty income generated by wells located in Oklahoma and allocable to the unitholders; accordingly, trust unitholders will be required to file Oklahoma state income tax returns and pay taxes in Oklahoma, and may be subject to penalties for failure to comply with such requirements. The highest marginal rates for the payment of Oklahoma state income taxes are 5.25% for individuals, trusts and estates, and 6% for corporations. Generally, Oklahoma taxpayers are entitled to a depletion allowance on oil and natural gas income for state income tax purposes equal to the greater of cost depletion or percentage depletion, with the percentage depletion allowance for most taxpayers being 22%, but not in excess of 50% of the gross income from the property; however, each trust unitholder should consult their own legal and tax advisors to determine the Oklahoma depletion allowance specifically applicable to such unitholder. Although payments to out-of-state interest owners, including beneficial owners such as trust unitholders, in respect of Oklahoma oil and natural gas income generally are subject to withholding for Oklahoma income tax purposes at the rate of 5%, an exception exists for publicly traded partnerships that furnish detailed information concerning beneficial owners to the Oklahoma Tax Commission. The trust plans to furnish such information and comply with those Oklahoma Tax Commission requirements as necessary to avoid withholding for Oklahoma state income tax purposes. Although Oklahoma municipalities are statutorily authorized to assess income taxes, no municipality has enacted such a tax. If any Oklahoma municipality were to enact an income tax, the tax could not be levied on nonresidents of the municipality.

        Kansas Income Taxes.    If the trust is treated as a partnership for U.S. federal income tax purposes, it will also be treated as a partnership for Kansas income tax purposes. Trust unitholders who are residents of Kansas will be subject to Kansas income tax on all trust royalty income allocable to the unitholders; provided, however, that a resident of Kansas may be eligible for a credit against the Kansas income tax for income taxes paid to another state. Trust unitholders who are not residents of Kansas will be subject to Kansas income tax on all trust royalty income allocable to the unitholders that is from Kansas sources. Accordingly, trust unitholders will be required to file Kansas state income tax returns and pay taxes in Kansas, and may be subject to penalties for failure to comply with such requirements. The highest marginal rates for the payment of Kansas state income taxes are 6.45% for individuals, trusts and estates, and 4% for corporations; however, a surtax of 3% is levied on taxable income of corporations in excess of $50,000. Although payments to out-of-state interest owners, including beneficial owners such as trust unitholders, in respect of Kansas oil and natural gas income generally are subject to withholding for Kansas income tax purposes at the rate of 6.45%, an exclusion exists for publicly traded partnerships. Consequently, the trust will not withhold for Kansas state income tax purposes.

ERISA CONSIDERATIONS

        The Employee Retirement Income Security Act of 1974, as amended (referred to as "ERISA"), regulates pension plans, profit-sharing plans, stock bonus plans, simplified employee pension plans, Keogh plans, tax deferred annuities and IRAs established or maintained by an employer or employee organization, and other employee benefit plans to which it applies. ERISA also contains standards for persons who are fiduciaries of those plans. In addition, the Internal Revenue Code provides similar requirements and standards which are applicable to pension and welfare plans, and to individual retirement accounts, whether or not subject to ERISA.

        A fiduciary of an ERISA-governed plan should carefully consider fiduciary standards under ERISA before authorizing an investment in trust units. Among other things, a fiduciary should consider:

        A fiduciary should also consider whether an investment in common units might result in nonexempt prohibited transactions under Section 406 of ERISA and Internal Revenue Code Section 4975. In general, to decide whether an investment will result in a prohibited transaction, a fiduciary must determine whether the transaction (1) constitutes a sale or exchange of property, an extension of credit, or the furnishing of goods or services between a fiduciary and an entity known as a "party in interest" under ERISA, (2) involves plan assets , employer securities or real property, or (3) creates a conflict of interest. The Department of Labor has published regulations concerning whether or not a qualified plan's assets would be deemed to include an interest in the underlying assets of an entity for purposes of the reporting, disclosure and fiduciary responsibility provisions of ERISA and analogous provisions of the Internal Revenue Code. These regulations provide that the underlying assets of an entity will not be considered "plan assets" if the equity interests in the entity are a publicly offered security. SandRidge expects that at the time of the sale of the trust units in this offering, they will be publicly offered securities.

        However, the prohibited transaction rules are complex, and persons involved in prohibited transactions are subject to penalties. For that reason, potential plan investors should consult with their counsel to determine the consequences under ERISA and the Internal Revenue Code of their acquisition and ownership of trust units.

UNDERWRITERS

        Subject to the terms and conditions in an underwriting agreement dated                        , 2012, the underwriters named below, for whom Morgan Stanley & Co. LLC and Raymond James & Associates, Inc. are acting as the representatives, have severally agreed to purchase from SandRidge the number of trust units set forth opposite their names:

Morgan Stanley & Co. LLC

       

Raymond James & Associates, Inc. 

       
       

Total

    25,000,000  
       

        The underwriters and the representatives are collectively referred to as the "underwriters" and the "representatives," respectively. The underwriters are obligated to take and pay for all of the common units offered by this prospectus, if any are taken, other than the common units covered by the option described below unless and until this option is exercised. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the common units are subject to a number of conditions, including, among others, the accuracy of the representations and warranties in the underwriting agreement, listing of the common units on the New York Stock Exchange, receipt of specified letters from counsel and the trust's and SandRidge's independent registered public accounting firm, and receipt of specified officers' certificates.

        Common units sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover page of this prospectus. Any common units sold by the underwriters to securities dealers may be sold at a price that represents a concession not in excess of $            per common unit under the initial public offering price. If all of the common units are not sold at the initial public offering price, the offering price and other selling terms may from time to time be varied by the representatives. The offering of the common units by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

        The trust has granted the underwriters an option to buy up to 3,750,000 additional common units from the trust at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. They may exercise that option for 30 days from the date of this prospectus. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase the same percentage of the additional common units as the number listed next to the underwriter's name in the preceding table bears to the total number of common units listed next to the names of all underwriters in the preceding table.

        If the underwriters do not exercise their option to purchase additional common units, the trust will issue 3,750,000 common units to SandRidge upon the option's expiration. If and to the extent the underwriters exercise their option to purchase additional common units, the number of common units purchased by the underwriters pursuant to such exercise will be issued to the public and the remainder, if any, will be issued to SandRidge. Accordingly, the exercise of the underwriters' option will not affect the total number of common units outstanding.

        The following table shows the amount per unit and total underwriting discounts the trust will pay to the underwriters (dollars in thousands, except per unit).

        The trust will pay Morgan Stanley & Co. LLC and Raymond James & Associates, Inc. a structuring fee of $            (or $            if the underwriters exercise their option to purchase additional trust units to cover over-allotments) for evaluation, analysis and structuring of the trust.

        SandRidge estimates that the expenses payable by SandRidge or the trust, excluding underwriting discounts and commissions, will be approximately $             million. In no event will the maximum amount of compensation to be paid to members of the Financial Industry Regulatory Authority, Inc. ("FINRA") in connection with this offering exceed 10%.

        The underwriters have informed the trust that they do not intend sales to discretionary accounts to exceed 5% of the total number of common units offered by them.

        The trust intends to apply to have the common units approved for listing on the New York Stock Exchange under the symbol "SDR."

        SandRidge has agreed with the underwriters, subject to specified exceptions, not to dispose of or hedge any of the common units or securities convertible into or exchangeable for common units during the period from the date of the preliminary prospectus continuing through the date 180 days after the date of this prospectus, except with the prior written consent of Morgan Stanley & Co. LLC and Raymond James & Associates, Inc.

        The 180-day restricted period described in the preceding paragraph will be automatically extended if: (1) during the last 17 days of the 180-day restricted period the trust issues a release concerning distributable cash or announces material news or a material event relating to the trust occurs; or (2) prior to the expiration of the 180-day restricted period, the trust announces that it will release distributable cash during the 16-day period following the last day of the 180-day period, in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or material event.

        The underwriters have informed SandRidge that they do not presently intend to release common units or other securities subject to the lock-up agreements. Any determination to release any common units or other securities subject to the lock-up agreements would be based on a number of factors at the time of any such determination; such factors may include the market price of the common units, the liquidity of the trading market for the common units, general market conditions, the number of common units or other securities subject to the lock-up agreements proposed to be sold, and the timing, purpose and terms of the proposed sale.

        In order to facilitate the offering of the common units, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common units. Specifically, the underwriters may sell more units than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of units available for purchase by the underwriters under the over-allotment option. The underwriters can close out a covered short sale by exercising the over-allotment option or purchasing units in the open market. In determining the source of units to close out a covered short sale, the underwriters will consider, among other things, the

117


Table of Contents

open market price of units compared to the price available under the over-allotment option. The underwriters may also sell units in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing units in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common units in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, common units in the open market to stabilize the price of the common units. These activities may raise or maintain the market price of the common units above independent market levels or prevent or retard a decline in the market price of the common units. The underwriters are not required to engage in these activities and may end any of these activities at any time.

        The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased units sold by or for the account of such underwriter in stabilizing or short covering transactions.

        SandRidge has agreed to indemnify the several underwriters and persons who control the underwriters against certain liabilities that may arise in connection with this offering, including liabilities under the Securities Act of 1933.

        Because FINRA views the common units offered under this prospectus as interests in a direct participatio
