Table of Contents

Q1:	What is the proposed transaction for which I am being asked to vote?
A1:	If you are a Darling stockholder you are being asked to vote to approve an asset purchase agreement entered into by and among Darling International Inc., National By-Products, LLC and a wholly-owned subsidiary of Darling, and the transactions contemplated by the asset purchase agreement, including the issuance of shares of Darling common stock in accordance with the asset purchase agreement. If you are a National By-Products unitholder you are being asked to vote to approve the asset purchase agreement by and among Darling, National By-Products and a wholly-owned subsidiary of Darling, and the transactions contemplated by the asset purchase agreement, including an amendment to the articles of organization of National By-Products to change its name to West-end Liquidation, LLC effective upon closing of the acquisition. The asset purchase agreement contemplates the purchase of substantially all of the assets of National By-Products by a newly formed and wholly-owned subsidiary of Darling. When the acquisition occurs, National By-Products will receive the acquisition consideration and distribute the acquisition consideration, less certain amounts, to its unitholders. See “The Asset Purchase Agreement — Consideration” beginning on page 63.
Q2:	Why did the companies enter into the asset purchase agreement?
A2:	Darling and National By-Products entered into the asset purchase agreement with the expectation that the acquisition will result in mutual benefits including, among other things, increasing revenue, diversifying raw material supplies and creating a larger platform to grow the restaurant services segment.
Q3:	What vote is required for approval of the proposals under consideration at the special meetings?
A3:	The asset purchase agreement and the issuance of shares of Darling common stock in the acquisition must be approved by a majority of the outstanding shares of Darling common stock, and the asset purchase agreement must be approved by a majority of the outstanding National By-Products membership units. Therefore, if you abstain or fail to vote, the effect will be the same as voting against the applicable proposal. You are entitled to vote on the applicable proposal if you held Darling common stock at the close of business on the Darling record date, which is April 6, 2006, or National By-Products membership units on the National By-Products record date, which is the date of the mailing of the notice of special meeting. On those dates, [                    ] shares of Darling common stock and 1,206,313 National By-Products membership units, respectively, were outstanding and entitled to vote. The adjournment proposal for each of the Darling stockholders and the National By-Products unitholders must be approved by the affirmative vote of a majority of the shares of Darling common stock or National By-Products membership units, as applicable, present in person or by proxy at the applicable special meeting, without regard to abstentions, even if there is no quorum at that meeting.
Q4:	What do I need to do now?
A4:	After carefully reading and considering the information contained in this joint proxy statement/ prospectus, please vote your shares or units, as applicable, as soon as possible so that your shares or units, as applicable, will be represented at your company’s special meeting. Please follow the instructions set forth on the proxy card or on the voting instruction form provided by the record holder if your shares or units, as applicable, are held in the name of your broker or other nominee.
Q5:	How do I vote?
A5:	If you are a Darling stockholder, you may vote before your special meeting in one of the following ways:

	•	use the toll-free number shown on your proxy card;
	•	visit the website shown on your proxy card to vote via the Internet; or

Table of Contents

	•	complete, sign, date and return the enclosed proxy card in the enclosed postage prepaid envelope.

	If you are a National By-Products unitholder, you may only vote before your special meeting by completing, signing, dating and returning the enclosed proxy card in the enclosed postage prepaid envelope.

Q6:	If my shares are held in “street name” by my broker or other nominee, will my broker or nominee vote my shares for me?
A6:	Your broker will vote your shares only if you provide instructions to your broker on how to vote. You should instruct your broker to vote your shares by following the directions provided to you by your broker. Without instructions, your broker will not vote any of your shares held in “street name” and the effect will be the same as a vote against the acquisition. See “The Special Meetings” beginning on page 36.
Q7:	What if I do not vote on the matters relating to the acquisition?
A7:	If you are a Darling stockholder and you fail to respond with a vote or fail to instruct your broker or other nominee how to vote on the acquisition proposal, it will have the same effect as a vote against the acquisition proposal. If you respond but do not indicate how you want to vote on the acquisition proposal, your proxy will be counted as a vote in favor of the acquisition proposal. If you respond and indicate that you abstain from voting on the acquisition proposal, your proxy will have the same effect as a vote against the acquisition proposal.

If you are a National By-Products unitholder and you fail to respond with a vote, it will have the same effect as a vote against the acquisition proposal. If you respond but do not indicate how you want to vote on the acquisition proposal, your proxy will be counted as a vote in favor of the acquisition proposal. If you respond and indicate that you abstain from voting on the acquisition proposal, your proxy will have the same effect as a vote against the acquisition proposal.

Q8:	May I change my vote after I have delivered my proxy card?
A8:	Yes. You can change your vote at any time before we vote your proxy at your special meeting. You can do so in one of the following ways:

	•	by sending a notice of revocation to the corporate secretary of Darling or National By-Products, as applicable;
	•	by sending a completed proxy card bearing a later date than your original proxy card; or
	•	by attending your special meeting and voting in person.

	If you are a Darling stockholder you can also change your vote at any time before we vote your proxy at your special meeting by logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically or by calling the telephone number specified on your proxy card, in each case if you are eligible to do so and by following the instructions on the proxy card. Your attendance alone will not revoke any proxy.
	If you choose to change your vote using any of the methods above, other than by attending your special meeting and voting in person, you must take the described action no later than the beginning of your special meeting or no later than the time indicated on your proxy card. If your shares are held in an account at a broker or other nominee, you should contact your broker or other nominee to change your vote.

Table of Contents

Q9:	If I hold National By-Products membership units, should I send them in order to receive the acquisition consideration?
A9:	No. You do not need to turn in your membership units or take other action to receive the acquisition consideration. The acquisition consideration will be sent to you by National By-Products subject to retention of such amounts by National By-Products as determined by its board of managers to be appropriate for purposes of satisfying obligations of National By-Products.

Q10:	Why am I receiving this document?
A10:	We are delivering this document to you as both a joint proxy statement of Darling and National By-Products and a prospectus of Darling. It is a joint proxy statement because each of Darling’s board of directors and National By-Products’ board of managers is soliciting proxies from its stockholders and unitholders, respectively. It is a prospectus because Darling will issue shares of its stock to National By-Products in the acquisition.
Q11:	Who should I call if I have additional questions or need additional copies of the joint proxy documents?
A11:	If you are a Darling stockholder and you would like additional copies of this joint proxy statement/ prospectus or a new proxy card or if you have questions about the acquisition, you should contact Brad Phillips at (972) 717-0300.

	If you are a National By-Products unitholder and you would like additional copies of this joint proxy statement/ prospectus or a new proxy card or if you have questions about the acquisition, you should contact David Pace at (515) 288-2166.

	•	On December 23, 2003, a cow originally imported from Canada to the state of Washington was diagnosed to have BSE. The U.S. government subsequently banned downer animals and specified risk materials (SRM) from food and cosmetics. Cattle that are tested for BSE are also prohibited from entering the food or feed chains until the animals are verified to be negative for the disease. On January 26, 2004, the FDA announced intentions to modify its BSE Feed Rule. Subsequently, on July 14, 2004, the FDA and USDA jointly requested public comment on possible actions to further mitigate the risk of BSE. On September 30, 2004, the FDA published a guidance document indicating that, pursuant to Section 402(a)(5) of the Federal Food, Drug, and Cosmetic Act, animal feed and feed ingredients containing material from a BSE-positive animal will be considered adulterated and may not be fed to animals.
	•	On June 24, 2005, a 12-year-old U.S.-born cow was diagnosed to have BSE. The animal was born more than four years before the FDA implemented the BSE Feed Rule in 1997. The cow was originally sampled at a pet food plant on November 18, 2004. Rapid screening tests for BSE were inconclusive and the carcass was incinerated so it did not enter the feed chain. Confirmation tests subsequently conducted by the USDA using immunohistochemistry (IHC) indicated the animal was negative for BSE. However, following an audit of the USDA’s enhanced BSE surveillance program by the Inspector General for USDA, the sample was retested on June 18, 2005 for BSE using the Western Blot technique, another internationally accepted confirmation test. The sample was positive for BSE using the Western Blot test. Because of the conflicting results obtained from the two test methods, the sample was sent to The Veterinary Laboratories Agency in Weybridge, England, where on June 24, 2005 it was confirmed to be positive for BSE. During the subsequent USDA investigation, 67 animals from the index herd were sacrificed, tested and found to be negative for BSE. In addition, the FDA investigation found the infected animal was fed in compliance to the BSE Feed Rule and did not receive MBM of ruminant animal origin after 1997, when the rule banning such practices went into effect. The FDA concluded the animal was most likely exposed to BSE before the BSE Feed Rule was promulgated.
	•	On March 13, 2006, the USDA announced that another cow in the U.S. was diagnosed to have BSE. Samples were taken from this non-ambulatory animal on a farm in the state of Alabama by a veterinarian who euthanized the animal and sent the samples for testing. Initial rapid screening tests for BSE were inconclusive, but subsequent tests using the Western Blot technique were positive for BSE. This cow did not enter the animal or human food chain. The USDA is currently performing epidemiological work to determine the animal’s precise age and origin. The Company’s management will continue to monitor this situation.
	•	A few major beef packing companies have begun selling SRM-free MBM for a premium to specific customers, primarily pet food manufacturers.
	•	As a result of the first BSE case, many foreign countries banned imports of U.S.-produced beef and beef products, including MBM. Tallow exports were briefly banned, but this initial ban was relaxed to permit imports of U.S.-produced tallow with less than 0.15% impurities. As of January 11, 2006, many foreign markets were closed to U.S. beef following the discovery of the first U.S. case of BSE, had been reopened, although some, such as Hong Kong, permit only boneless beef from U.S. cattle less than 30 months of age to be imported. Steps towards regaining the major former export markets of Japan, the largest, and South Korea, the second largest, had also been made. On December 12, 2005, Japan eased its ban by permitting meat from U.S. cattle less than 21 months of age to be imported. Two days later, South Korea’s agriculture ministry concluded that U.S. beef was not a health concern, which may be an important step towards lifting that country’s ban. On January 20, 2006, however, Japan suspended imports of U.S. beef because one shipment contained

		vertebral column, in violation of the terms of the agreement between the U.S. and Japan. The USDA immediately implemented protocols to prevent such violations in the future and began negotiations with Japan to lift the suspension. Except for Indonesia, export markets for MBM containing beef material produced in the U.S. have generally remained closed. Indonesia reopened its border to pork-free MBM in March 2005, but re-initiated its ban on U.S. MBM following the announcement that a second case of BSE had been found in the U.S.
	•	In May 2003, the USDA closed the border to live cattle and beef from Canada after a cow with BSE was discovered there. Boneless beef derived from Canadian cattle under 30 months of age was later approved for importation into the U.S. Canadian officials found two additional cases of BSE in December 2004 and January 2005. On January 4, 2005, the USDA published a Final Rule establishing criteria for classifying geographic regions as presenting minimal-risk of introducing BSE into the U.S. This same rulemaking placed Canada into the minimal-risk category based on an extensive investigation by USDA veterinarians. Based on this classification, USDA announced its intent to reopen the Canadian border to live cattle under 30 months of age and beef from such cattle beginning March 7, 2005. Imports of SRM-free beef from cattle over 30 months of age were also to be allowed, but this action was tabled by the Secretary of Agriculture on February 9, 2005 to allow time for further study. The Ranchers — Cattlemen Action Legal Fund — United Stock Growers of America (R-CALF) sued the USDA and, on March 2, 2005, was granted a temporary injunction by the U.S. District Court for the District of Montana, which prevented implementation of the Minimal Risk Rule and kept the border closed to Canadian cattle. On July 14, 2005, the U.S. Ninth Circuit Court of Appeals agreed with the USDA and overturned the lower court’s temporary injunction, reopening the Canadian border to cattle less than 30 months of age. The first Canadian cattle were imported into the U.S. on July 18, 2005. The importation of SRM-free beef from Canadian cattle over 30 months of age continues to be banned.

	•	On October 6, 2005, the FDA proposed to amend the agency’s regulations to prohibit certain cattle origin materials in the food or feed of all animals, which we refer to as the “Proposed Rule.” The materials that are proposed to be banned include: (1) the brain and spinal cord from cattle 30 months and older that are inspected and passed for human consumption; (2) the brain and spinal cord from cattle of any age not inspected and passed for human consumption; and (3) the entire carcass of cattle not inspected and passed for human consumption if the brains and spinal cords have not been removed. In addition, the Proposed Rule provides that tallow containing more than 0.15% insoluble impurities also be banned from all animal food and feed if such tallow is derived from the proposed prohibited materials. Proposed rules are not regulations and are not enforceable. Such proposals are published to obtain public comment on actions that the agency is considering. The 75-day public comment period for the Proposed Rule closed December 20, 2005. The FDA is currently reviewing the comments submitted and has not taken any further action. Darling’s management will continue to monitor this and other regulatory issues.
	•	Effective October 7, 2005, the FDA amended its July 14, 2004 interim final rule, which prohibited the use of SRM for human food and required that tallow intended for use in human food and cosmetics contain less than 0.15% impurities. The FDA amended its original interim final rule to remain consistent with rulemaking by the Food Safety Inspection Service of the USDA regarding SRM, which was also effective on October 7, 2005. In the amended final rule, the FDA permits the use of beef small intestine for human food, provided the last 80 inches (distal ileum) of small intestine is removed and the small intestine is derived from cattle that have been inspected and passed for human consumption. The FDA also amended its list of acceptable methods for measuring insoluble impurity levels in tallow to include the methods commonly used by the tallow industry. The impurities limit does not apply to tallow used to make tallow-derivatives (fatty acids).

	Darling has debt and interest payment requirements that could adversely affect its ability to operate its business.

	•	if the acquisition is consummated, Darling will be required to use approximately $8.9 million of its cash flow from operations in Fiscal 2006 to pay its indebtedness, thereby reducing the availability of its cash flow to fund the implementation of Darling’s business strategy, working capital, capital expenditures, product development efforts and other general corporate purposes;
	•	Darling’s interest expense could increase if interest rates in general increase because a portion of Darling’s debt will bear interest based on market rates;
	•	Darling’s level of indebtedness will increase its vulnerability to general adverse economic and industry conditions;
	•	Darling’s debt service obligations could limit Darling’s flexibility in planning for, or reacting to, changes in Darling’s business;
	•	Darling’s level of indebtedness may place it at a competitive disadvantage compared to its competitors that have less debt; and
	•	a failure by Darling to comply with financial and other restrictive covenants in the agreements governing Darling’s indebtedness could result in an event of default and could have a material adverse effect on Darling.

	•	On January 26, 2004, the FDA announced intentions to modify its feed rule (21 CFR 589.2000) by removing the exemptions for certain products, including blood and blood products, and requiring dedicated processing lines for handling and processing restricted use and exempted proteins. On July 14, 2004, the FDA requested public comment on their intended modifications to the feed rule as well as regulations that would: 1) prohibit material derived from SRM and dead or non-ambulatory cattle in animal feed; 2) prohibit all animal proteins in feed for ruminant animals;

		and/or 3) require that only BFT either derived from SRM-free material or containing less than 0.15% impurities be allowed in animal feed. Only questions were posed in this announcement of proposed rulemaking, to which National By-Products, among others, responded in comments submitted to the FDA. No new regulations affecting animal feed or modifying the feed rule have been issued to date. This situation will likely continue to be fluid into Fiscal 2006.
	•	On January 26, 2004, the FDA announced its intent to ban the use of certain animal tissue derived materials in food and supplements. Subsequently, on July 14, 2004, the FDA published regulations prohibiting: 1) SRM from human food and cosmetics; and 2) SRM and non-ambulatory or dead cattle from cosmetics. BFT that is either derived from SRM-free raw materials or contains less than 0.15% hexane insoluble impurities will be permitted in human food, supplements and cosmetics. Derivatives of BFT (glycerin and fatty acids) are exempt from these regulations. On September 30, 2004, the FDA issued Guidance Document #174 , which cited the agency’s statutory authority to consider animal feed and feed ingredients derived from a BSE-positive animal to be adulterated and prohibit the use of adulterated material in animal feed.

	Summary of Valuation Methods

	Value to Be Received by National By-Products Unitholders

	1) Cash. Cash of $70.5 million will be paid by Darling to National By-Products less an estimated $1.9 million (determined as of December 16, 2005) to repay borrowed debt for a net cash payment of $68.6 million. Borrowed debt at closing may be more or less than this amount.
	2) Working Capital. Working capital was assumed by Schneider to be $5 million which will be paid by Darling to National By-Products. Working capital at closing may be more or less than this amount.
	3) Darling Stock. Schneider assumed 16,222,750 shares of Darling common stock would be issued to National By-Products with an assumed market value of $3.50 per share less a 5% marketability discount due to restrictions on the sale of Darling common stock by National By-Products unitholders. The result was a value of $53,940,644.
	4) True-up Provision. Additional shares of Darling common stock will be issued in the acquisition if the future value of Darling common stock is less than a specified target price, assumed to be $4.346 per share. Using the Black-Scholes option pricing model, Schneider determined the true-up provision had a value of approximately $6,231,417.

(1)	The Closing Share Price will be an amount equal to the per share closing price of Darling common stock on the AMEX (as reported by The Wall Street Journal, Eastern Edition, or if not reported thereby, any other authoritative source) for the trading day immediately preceding the closing date of the acquisition. The Closing Share Price cannot be determined until the closing of the acquisition. For purposes of this illustration, we used the per share closing price of Darling common stock on March 23, 2006.
(2)	The number of Closing Issued Shares cannot be determined until the closing of the acquisition. For purposes of this illustration, we used 20% of the outstanding shares of Darling common stock on March 23, 2006, calculated on a fully-diluted basis, assuming the issuance of the Closing Issued Shares.
(3)	The Value of the Shares at Closing is calculated by multiplying the Closing Share Price by the Closing Issued Shares. This number represents the aggregate value of the stock consideration issued to National By- Products immediately following the closing of the acquisition, and includes the $6.5 million in value of escrowed shares.
(4)	The Target Share Price is the per share price of Darling common stock that would cause the value of the stock consideration issued to National By-Products at closing to be $70.5 million. This number is

64

---

Table of Contents

	generated by dividing $70.5 million by the number of Closing Issued Shares. The Target Share Price in this example is $4.30208627.
(5)	These per share prices represent various reference prices for the true-up market price.
(6)	This illustration assumes that none of the National By-Products unitholders have transferred any of their Closing Issued Shares (except transfers by gift or into trust) and that no escrowed shares are released to Darling in accordance with the escrow agreement.
(7)	The Value Gap is calculated by multiplying (A) the Remaining Issued Shares by (B) the difference between (x) the Target Share Price and (y) the higher of the True-Up Market Price or $3.60; provided that the difference in (B) is a positive number, if not, then the Value Gap will be zero.
(8)	The number of True-Up Shares is determined by dividing (A) the Value Gap by (B) the higher of (x) the True-Up Market Price and (y) $3.60, rounded to the nearest whole number.

	1. Amendment #1, dated September 30, 2000 — to decrease the restrictive covenant on tangible net worth from $23.0 million to $18.0 million.
	2. Amendment #2, dated January 28, 2002 — to allow for the conversion of National By-Products to a limited liability company; to allow for a supplemental term loan facility of $6.0 million to be used for capital gains tax distributions and purchases of equity interests; and to eliminate the 25% prepayment requirement of free cash flow, among other changes.
	3. Amendment #3, dated March 31, 2003 — to allow for special distributions up to 100% of free cash flow limited to $10.0 million; to increase the tangible net worth restrictive covenant to $31.0 million; and to eliminate the liens on National By-Products’ tractors and trailers, among other changes.
	4. Amendment #4, dated July 2, 2004 — to eliminate the $10.0 million limitation on special distributions; to extend the term by two years to June 30, 2007; and to increase the revolving credit facility from $16.0 million to $21.0 million, among other changes.

	•	Financing facilities, consisting of a $27.0 million term loan facility, a $6.0 million supplemental term loan facility, and a $21.0 million revolving facility, which includes a $5.0 million letter of credit subfacility.

	•	Term of seven years maturing on June 30, 2007.
	•	Scheduled amortization payments on the term loan facility of $1.0 million, due each quarter during the original five-year term of the amended and restated credit. The term loan facility was paid in full during 2003.

Authorized Capital Stock:		The authorized capital stock of Darling currently consists of (i) 100,000,000 shares of common stock, par value $0.01 per share, and (ii) 1,000,000 shares of preferred stock, par value $0.01 per share.		The total number of units of all classes of National By-Products currently consists of (i) 15,000,000 common units and (ii) 5,000,000 preferred units.
Number of Directors:		The Darling board of directors currently consists of six directors. The number of directors is established from time to time by resolution of the Darling board of directors, although there must be a minimum of five and not more than eleven directors.		The National By-Products board of managers consists of nine managers. The number of managers may not be less than three or more than nine, the number within the range to be determined from time to time by a majority vote of the entire board.
Election of Directors/Managers:		Directors are elected by a plurality of the votes cast at a meeting of the stockholders entitled to vote in the election of the directors. The Chairman of the Board is selected by a majority of the board of directors.		If a quorum is present, managers are elected by a majority of the units represented at the meeting and entitled to vote. Nominations of managers by members may be made only in accordance with procedures set forth in the bylaws.

The terms of office of managers of the first class expire at the first annual meeting of members after their election, the terms of office of managers in the second class expire at the second annual meeting of members after their election, and the terms of office of the managers of the third class expire at the third annual meeting of members after their election. At each annual meeting of members, the number of managers equal to the number of the class whose term expires at the time of the meeting will be elected to hold office until the third succeeding meeting.
Removal of Directors/Managers:		Not addressed in Darling’s certificate of incorporation or the bylaws. Delaware law provides that the holders of a majority of the shares then entitled to vote at an election of directors may remove, with or without cause, any director or the entire board of directors.		At a meeting called expressly for that purpose, any manager may be removed at any time, with or without cause, by vote of the members holding at least two- thirds of the outstanding units.
Vacancies on the Board:		Vacancies in Darling’s board of directors and newly created directorships resulting from any increase in the authorized number thereof may be filled by a majority of the remaining directors then in office, although less than a quorum, or by a sole remaining director, and the directors so elected will hold office until the next annual stockholders meeting and until their successors are duly elected and qualified, or until their earlier death, resignation, retirement, disqualification or removal.		Vacancies in National By- Products’ board of managers occurring prior to the expiration of the term of a manager or as a result of new managerships created by an increase in the number of managers will only be filled by a majority vote of the remaining managers constituting the board. An additional manager holds office until his or her successor is designated as manager and is elected and qualified or his or her earlier death, resignation or removal.
Board Quorum and Vote Requirements:		At all meetings of Darling’s board of directors, a majority of directors constitutes a quorum for the transaction of business, and the act of a majority present at any meeting at which there is quorum is the act of the board of directors.		A quorum for a meeting of the board of managers consists of a majority of all managers. At all meetings of the board of managers, a quorum being present, the act of a majority of the managers present at the meeting will be the act of the board of managers, unless the vote of a greater number is

				otherwise affirmatively and expressly required by the Iowa Limited Liability Company Act or other applicable law.
Board Action without a Meeting:		Any action required or permitted to be taken at any meeting of Darling’s board of directors (or a committee) may be taken without a meeting if all members of the board of directors or committee consent to the action in writing, and that writing or those writings are filed with the minutes of proceedings of the board of directors or committee.		Any action required or permitted to be taken at any meeting of National By-Products’ board of managers may be taken without a meeting if the action is taken by all managers and if one or more consents in writing describing the action so taken will be signed by each manager and included in the minutes or filed with National By-Products’ records reflecting the action taken. Any written consent will be effective when the last manager signs the consent, unless the consent specifies a different effective date.
Stockholder/Unitholder Meetings:		All meetings of Darling’s stockholders for the election of directors are held at the place as may be fixed from time to time by the board. Meetings of Darling’s stockholders for any other purpose are held at the time and place, either within or without the State of Delaware, as stated in the notice of the meeting. Annual meetings are held on the second Monday of May, if not a legal holiday, otherwise the next regular business day, at 10:00 a.m., or at another date and time as designated from time to time by the board.		An annual meeting of the members for the purpose of electing managers and for the transaction of other business as may come before the meeting will be held each year on the third Tuesday in May, at 10:00 a.m.; provided that the board of managers may fix some other date or time for the meeting. If the day designated above or fixed by the board of managers for the annual meeting will be a Sunday or other legal holiday in the state where held, the meeting will be held on the next succeeding business day.
		Special meetings of the stockholders of Darling for any purpose or purposes may be called at any time by the board of directors, the chief executive officer, the president or the holders of at least ten percent of Darling’s outstanding shares of capital stock.		Special meetings of National By- Products’ members, for any purpose, may be called by (i) the chairman of the board of managers, (ii) the president or (iii) the board of managers, and will be called by the board of managers at the request of any member or members holding at least ten percent of the outstanding units entitled to vote at the meeting.

Stockholder/Unitholder Proposals:		Business transacted at any special meeting of stockholders is limited to the purposes stated in the notice unless all of the stockholders are present in person or by proxy, in which case any and all business may be transacted at the meeting even though the meeting is held without notice.		For business to be properly brought before an annual meeting by a member, business must be (i) specified in the notice of meeting (or supplement thereto) given by or at the direction of the board of managers, (ii) otherwise properly brought before the meeting by or at the direction of the board of managers, or (iii) otherwise properly brought before the meeting by a member in accordance with National By-Products’ bylaws. Business may be properly brought before an annual meeting by a member only if written notice of the member’s intent to propose the business has been delivered, either by personal delivery, United States mail, first class postage prepaid, or other comparable means to National By-Products’ Secretary not later than the close of business on the tenth day following the day on which notice of the date of the meeting was first mailed to members.
Action of Stockholders and Unitholders by Written Consent:		Any action required or permitted to be taken by Darling’s stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, will be signed by the holders of the outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take the action at a meeting at which all shares		Action required or permitted to be taken at a meeting of members may be taken without a meeting and without notice if the action is evidenced by one or more written consents describing the action taken, signed by members holding at least ninety percent of the outstanding units entitled to vote and delivered to the board of managers for inclusion in the minutes or for filing with National By-Products’

Voting Rights:		Each outstanding share, regardless of class, has the right to one vote on each matter submitted to a vote at a meeting of stockholders.		Except as may be provided with regard to series preferred units, members have one vote for each unit and are entitled to vote on any matter on which the vote of the members is taken.
Dividend/Distribution Rights:		Darling’s ability to pay any cash or non-cash dividends on its common stock is subject to applicable provisions of state law and to the terms of its credit agreements. Under Delaware law, Darling is permitted to pay cash or accumulated dividends on Darling’s capital stock, including Darling’s common stock, only out of surplus, or if there is no surplus, out of Darling’s net profits for the fiscal year in which a dividend is declared or for the immediately preceding fiscal year. Surplus is defined as the excess of a company’s total assets over the sum of its total liabilities plus the par value of its outstanding capital stock. In order to pay dividends, Darling must have surplus or net profits equal to the full amount of the dividends at the time the dividend is declared. In determining Darling’s ability to pay dividends, Delaware law permits Darling’s board of directors to revalue Darling’s assets and liabilities from time to time to their fair market values in order to establish the amount of surplus.		National By-Products’ operating agreement provides that the board of managers will not declare a distribution if, after the distribution is made: (a) National By-Products would not be able to pay its debts as they come due in the usual course of business, (b) National By-Products’ total assets would be less than the sum of its total liabilities, plus the amount that would be needed (if any), if National By-Products were to be dissolved at the time of the distribution, to satisfy preferential rights upon dissolution of members whose preferential rights are superior to the rights of members receiving the distribution or (c) the payment of the distribution would be a default by National By-Products under its credit agreement. Because income of National By- Products is allocated to its members for income tax purposes, on or before April 15 of each year, National By- Products is required to distribute cash to its members in at least the amount estimated to equal the income taxes payable by its members.
Appraisal Rights:		Under Delaware General Corporation Law § 262, Darling’s stockholders have rights to seek appraisal of the fair value of shares in certain circumstances, which do not apply to this acquisition.		Members have the same appraisal rights as shareholders of an Iowa corporation. Under the Iowa Business Corporation Act § 490.1302 National By-Products’ unitholders have rights to seek appraisal of the fair value of units in certain circumstances,

				including the proposed acquisition by Darling.
Amendment of Certificate of Incorporation/Articles of Organization:		Not addressed in Darling’s certificate of incorporation or its bylaws; however, the Delaware General Corporation Law provides that the board of directors will adopt a resolution setting forth the amendment proposed and declaring its advisability. Stockholders will either vote at the next annual meeting or at a special meeting, as determined by the board. The board of directors must send notice of the meeting that sets forth the amendment in full or a brief summary of the changes. To pass the proposed amendment, a majority of the outstanding stock must be voted in favor of the amendment.		An amendment to National By- Products’ articles of organization requires a majority vote of the outstanding units entitled to vote.
Amendment of Bylaws/Operating Agreement:		Darling’s bylaws may be amended, altered or repealed or new bylaws may be adopted by the stockholders or by the board of directors at any regular meeting of the stockholders or board of directors or any special meeting of the stockholders or board of directors if notice of the alteration, amendment, repeal or adoption of new bylaws is contained in the notice of the special meeting.		An amendment to National By- Products’ operating agreement requires a majority vote of the outstanding units entitled to vote. Its bylaws may be amended by its board of managers.
Exculpation of Directors:		Darling’s certificate of incorporation provides that a director will not be personally liable to Darling or its stockholders for monetary damages for breach of fiduciary duty as a director; except for liability (i) for any breach of the director’s duty of loyalty to Darling or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law (relating to unlawful payment of dividends or unlawful stock purchase or redemption), or (iv) for any transaction from		A manager of National By- Products will not be personally liable to National By-Products or to its members for monetary damages for breach of fiduciary duty as manager, except for liability (i) for breach of the manager’s duty of loyalty to National By-Products or to its members, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, or (iii) for a transaction from which the manager derives an improper personal benefit or a wrongful distribution in violation of the Iowa Limited Liability Company Act.

		which the director derived an improper personal benefit.
Indemnification of Directors/Managers, Officers and Employees:		Darling will indemnify its officers, directors, employees and other agents, and those who served at the request of Darling as an officer, director, employee, or agent of another entity who are a party to or are threatened to be made a party to any threatened, pending or completed action, suit or proceeding.		National By-Products will indemnify each person who is or was a manager or officer who was or is made a party to or a witness in, or is threatened to be made a party to or a witness in any threatened, pending or completed claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including a grand jury proceeding) and whether formal or informal, by reason of the fact that the person (i) is or was a manager or officer of National By-Products or (ii) while a manager or officer of National By-Products, is or was serving at the request of the company as a manager, member, director, officer, partner, trustee, employee or agent of another individual, person or entity.
		Expenses (including attorneys’ fees) incurred by an officer or director in defending a civil, criminal, administrative or investigative action, suit or proceeding will be paid by Darling in advance of the final disposition of the action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined that he is not entitled to be indemnified by Darling. Expenses (including attorneys’ fees) incurred by other employees and agents may be so paid upon the terms and conditions, if any, as the board of directors deems appropriate.		National By-Products will reimburse reasonable expenses incurred in connection with any claim, action, suit or proceeding in advance of its final disposition; provided however, that the payment or reimbursement of the expenses in advance of the final disposition of the claim, action, suit or proceeding will be made only upon delivery to National By-Products of (i) a written undertaking by or on behalf of the person claiming indemnification to repay all amounts so advanced if it is ultimately determined that the person is not entitled to be indemnified and (ii) a written affirmation of the person’s good faith belief that the person has met the applicable standard of conduct necessary to require indemnification by National By-Products.
