ENTERRA ENERGY TRUST

Our business

We may undertake acquisitions that could limit our ability to manage and maintain our business, result in adverse accounting treatment and are difficult to integrate into our business. Any of these events could result in a material change in our liquidity, impair our ability to pay dividends and could adversely affect the value of your investment.

CAPITALIZATION

An unlimited number of trust units may be created and issued pursuant to our trust indenture. Each trust unit entitles the holder thereof to one vote at any meeting of the unitholders and represents an equal fractional undivided beneficial interest in any distribution from us, including net income, net realized capital gains or other amounts, and in our net assets in the event of termination or winding up of our business. All trust units rank among themselves equally and ratably without discrimination, preference or priority. Each trust unit is transferable, is not subject to any conversion or pre-emptive rights and entitles the holder thereof to require us to redeem any or all of the trust units held by such holder.

In conjunction with our reorganization we issued exchangeable shares that are intended to be the economic equivalent of trust units. We issued a total of 2,000,000 exchangeable shares.

The exchangeable shares are convertible at any time into trust units at the option of the holder based on an exchange ratio. The exchange ratio is increased monthly based on the cash distribution paid on the trust units divided by the ten day weighted average unit price preceding the distribution payment date. From November 25 to December 31, 2003, a total of 4,404 exchangeable shares were converted into 4,404 trust units at the exchange ratio of 1:1 prevailing at the time. Cash distributions are not paid on the exchangeable shares. On the third anniversary of the issuance of the exchangeable shares, subject to our extension or, at our option at any time when the aggregate number of issued and outstanding exchangeable shares is less than 1,000,000, the exchangeable shares will be redeemed for trust units based upon the exchange ratio in effect on the redemption date. The exchangeable shares are not listed for trading on an exchange.

There is no law or government decree or regulation in Canada that restricts the export or import of capital, or affects the remittance of dividends, interest or other payments to non-resident holders of trust units, other than withholding tax requirements.

There is no limitation imposed by Canadian law or by our trust indenture on the right of a non-resident to hold or vote our trust units, other than as provided by the Investment Canada Act, the North American Free Trade Agreement Implementation Act (Canada) and the World Trade Organization Agreement Implementation Act. The Investment Canada Act requires notification and, in certain cases, advance review and approval by the Government of Canada of the acquisition by a "non-Canadian" of "control" of a "Canadian business," each as defined in the Investment Canada Act. In general, the threshold for review will be higher in monetary terms for a member of the World Trade Organization or North American Free Trade Agreement.

The transfer agent and registrar for our trust units is Olympia Trust Company at its principal offices in Calgary and Toronto, Canada.

In January 2004 Glickenhaus & Co., a registered investment advisor residing at 6 East 43rd Street, New York, NY 10017, committed to purchase 1,650,000 trust units from us in a privately negotiated transaction at US$10.00 per unit. We have agreed that that Glickenhaus & Co. will pay us on our delivering to it registered trust units.

Glickenhaus & Co. may, from time to time, offer and sell up to 1,650,000 trust units as a selling unitholder under this prospectus. Our registration of the trust units does not necessarily mean that the selling unitholder will sell all or any of the trust units covered by this prospectus. As the selling unitholder is a registered broker-dealer, they are deemed to be an "underwriter" under interpretations of the Securities and Exchange Commission and within the meaning of the Securities Act.

The selling unitholder presently owns 198,600 trust units, or approximately 0.9% of our total outstanding trust units and exchangeable shares. Upon completion of this transaction they will beneficially own 1,848,600 trust units or approximately 7.8% of our total outstanding trust units and exchangeable shares. Because the selling unitholder may offer all or some of their trust units from time to time, we cannot estimate the number of trust units that will be held by the selling unitholder upon the termination of any particular offering. See "Plan of Distribution."

The percentage of total trust units outstanding prior to this transaction is calculated based upon 23,610,956 trust units, including 1,955,596 trust units issuable for exchangeable shares, as of March 31, 2004.

Sales of the trust units covered by this prospectus may be effected from time to time in transactions (which may include block transactions) on the Nasdaq National Market, Toronto Stock Exchange, or other markets on which our trust units are traded.

Sales effected through negotiated transactions, through put or call option transactions relating to the units, through short sales of units, or a combination of such methods of sale, at fixed prices which may be changed, at market prices prevailing at the time of sale, or at negotiated prices. The selling unitholder has not entered into agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their units. The selling unitholder may effect transactions by selling their units directly to purchasers or through broker-dealers, who may act as agents or principals. Such broker-dealers may receive compensation in the form of discounts, concessions, or commissions from the selling unitholder and/or the purchasers of the units for whom such broker-dealers may act as agents, or to whom they sell as principal, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions).

The selling unitholder and any broker-dealers who act in connection with the sale of the units might be deemed to be underwriters within the meaning of Section 2(11) of the Securities Act of 1933 and any commissions received by such broker-dealers and any profit on the resale of the units sold by them while acting as principals might be deemed to be underwriting discounts or commissions under the Securities Act. We have agreed to indemnify the selling unitholder against a number of liabilities, including liabilities arising under the Securities Act. The selling unitholder may agree to indemnify any agent, dealer or broker-dealer who participates in transactions involving sales of the securities against the liabilities, including liabilities arising under the Securities Act. As used herein, "selling unitholder" includes affiliates, nominees, distributees, donees and pledgees selling units received from a named selling unitholder after the date of this prospectus.

The selling unitholder also may resell all or a portion of the units in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of such Rule.

We have agreed to keep the registration statement, of which this prospectus is a part, effective until all the units covered by this prospectus are sold or can be sold freely under an appropriate exemption from the securities laws of the United States and the states, without limitation.

In order to comply with the applicable state securities laws, the units covered by this prospectus will be offered or sold through registered or licensed brokers or dealers in those states. In addition, in a number of states the units may not be offered or sold unless they have been registered or qualified for sale in such states, or an exemption from such registration or qualification requirement is available and such offering or sale is in compliance therewith.

Under applicable rules and regulations under the Exchange Act, any person engaged in a distribution of the units may not simultaneously engage in market making activities with respect to such securities for a period beginning when such person becomes a distribution participant and ending upon such person’s completion of participation in a distribution, including stabilization activities in the trust units to effect syndicate covering transactions, to impose penalty bids or to effect passive market making bids. In addition, the selling unitholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Rule 10b-5 and, insofar as the selling unitholder is a distribution participant, Regulation M and Rules 100, 101, 102, 103, 104 and 105 thereof, all of which may affect the marketability of the units covered by this prospectus.

We will pay all of the expenses relating to the registration of the units covered by this prospectus, except that the selling unitholder will pay any underwriting commissions and expenses, brokerage fees, transfer taxes and the fees and expenses of their attorneys and other experts. The following table sets forth expenses payable by us in connection with the registration of the trust units. All amounts are estimates except the SEC registration fee.

The following is a summary of the material Canadian federal income tax considerations under the Income Tax Act (Canada) (the "Tax Act") in respect of the acquisition of trust units pursuant this offering generally applicable to purchasers who (i) hold trust units as capital property for purposes of the Tax Act, and (ii) at all material times deal at arm's length, and are not affiliated, with Enterra and New Enterra for purposes of the Tax Act. Generally, trust units will be considered to be capital property to a holder who does not hold such securities in the course of carrying on a business and has not acquired them in one or more transactions considered to be an adventure in the nature of trade. Certain Canadian resident unitholders who might not otherwise be considered to hold their trust units as capital property may, in certain circumstances, be entitled to make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have such trust units treated as capital property.

This summary is not applicable to either a unitholder that is a "financial institution" or a "specified financial institution", as defined for purposes of the Tax Act, or a unitholder, an interest in which would be a "tax shelter investment" under the Tax Act.

This summary is based upon the provisions of the Tax Act and the regulations thereunder ("Tax Regulations") in force as of the date hereof, all specific proposals to amend the Tax Act and the Tax Regulations that have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the "Proposed Amendments") and Canadian counsel's understanding of the current published administrative and assessing policies of the Canada Customs and Revenue Agency (the "CCRA").

This summary is not exhaustive of all possible Canadian federal income tax considerations applicable to the acquisition of trust units and, except for the Proposed Amendments, does not take into account or anticipate any changes in the law, whether by legislative, governmental or judicial action or changes in the administrative and assessing practices of the CCRA. This summary does not take into account any provincial, territorial or foreign tax considerations, which may differ significantly from those discussed herein.

This summary is of a general nature only and it should not be relied on as legal or tax advice or representations to any particular investor. Potential investors are urged to seek independent tax advice in respect of the consequences to them of the acquisition of trust units having regard to their particular circumstances.

This portion of the summary is applicable to a unitholder who, for the purposes of the Tax Act and at all relevant times, is resident, or deemed to be resident, in Canada.

Based upon a certificate from New Enterra, the Trust qualifies as a mutual fund trust under the provisions of the Tax Act and the balance of the summary assumes that the Trust will continue to so qualify. The Trust has registered as a "registered investment" under the Tax Act from inception, and this summary further assumes that the Trust continues to be so registered.

The requirements to qualify as a mutual fund trust for purposes of the Tax Act include:

1. the sole undertaking of the Trust must be the investing of its funds in property (other than real property or interests in real property), the acquiring, holding, maintaining, improving, leasing or managing of any real property (or an interest in real property) that is capital property of the Trust, or any combination of these activities;

2. the Trust must comply on a continuous basis with certain requirements relating to the qualification of the trust units for distribution to the public, the number of unitholders and the dispersal of ownership of trust units. In this regard, there must be at least 150 unitholders, each of whom owns not less than one "block" of trust units having a fair market value of not less than $500. A "block" of trust units means 100 trust units if the fair market value of one trust unit is less than $25; and

3. continuously from the time of its creation, all or substantially all of the Trust's property must consist of property other than property that would be "taxable Canadian property" for purposes of the Tax Act.

The Trust has certain restrictions on its activities and its powers and certain restrictions on the holding of taxable Canadian property, such that it is reasonable to expect that the requirements will be satisfied. However, Canadian counsel can provide no assurances that the requirements will continue to be met.

If the Trust were not to so qualify as a mutual fund trust or were not to be registered as a registered investment from inception, the income tax considerations would in some respects be materially different from those described below.

The Trust is subject to tax in each taxation year on its income or loss for the year, computed as though it were a separate individual resident in Canada. The taxation year of the Trust will end on December 31 of each year.

The Trust will be required to include in its income for each taxation year (i) all interest on the Series A Notes that accrues to, becomes receivable or is received by it before the end of the year, except to the extent that such interest was included in computing its income for a preceding year (ii) all interest on the CT Note that accrues to, becomes receivable or is received by it before the end of the year, except to the extent that such interest was included in computing its income for a preceding year (iii) the net income of Commercial Trust paid or payable to the Trust in the year and (iv) all amounts in respect of any oil and gas royalties, if any, held by the Trust including any amounts required to be reimbursed to the grantor of the royalty in respect of Crown charges.

In computing its income, the Trust will generally be entitled to deduct reasonable administrative expenses incurred to earn income. The Trust will be entitled to deduct the costs incurred by it in connection with the issuance of trust units on a five-year, straight-line basis (subject to pro-ration for short taxation years). The Trust may also deduct amounts which become payable by it to unitholders in the year, to the extent that the Trust has net income for the year after the inclusions and deductions outlined above and to the extent permitted under the Tax Act. An amount will be considered to have become payable to a unitholder in a taxation year only if it is paid in that year by the Trust or the unitholder is entitled in that year to enforce payment of the amount. Under the Trust Indenture, net income of the Trust for each year will be paid or made payable by way of cash distributions to the unitholders. The Trust Indenture also contemplates other situations in which the Trust may not have sufficient cash to distribute all of its net income by way of such cash distributions. In such circumstances, such net income will be payable to unitholders in the form of the issuance by the Trust of additional trust units ("Reinvested trust units"). Accordingly, it is anticipated that the Trust will generally not have any taxable income for the purposes of the Tax Act.

Under the Trust Indenture, income received by the Trust may be used to finance cash redemptions of trust units. A redemption of trust units that is effected by a distribution by the Trust to a unitholder of Series A Notes will be treated as a disposition by the Trust of such Series A Notes for proceeds of disposition equal to the fair market value thereof and may give rise to a taxable capital gain to the Trust.

The Trust will be entitled for each taxation year to reduce (or receive a refund in respect of) its liability, if any, for tax on its net taxable capital gains by an amount determined under the Tax Act based on the redemption or retraction of trust units during the year (the "Capital Gains Refund"). In certain circumstances, the Capital Gains Refund for a particular taxation year may not completely offset the Trust's tax liability on net realized capital gains for such taxation year.

For purposes of the Tax Act, the Trust generally intends to deduct, in computing its income and taxable income, the full amount available for deduction in each year. As a result of such deductions and the Trust's entitlement to a Capital Gains Refund, it is expected that the Trust will not be liable for any material amount of tax under the Tax Act. However, no assurance can be given in this regard.

The Trust has registered be a "registered investment" under the Tax Act from the Trust's inception. The Trust may have its registration revoked by the CCRA if it ceases to be a mutual fund trust and did not otherwise qualify for registered investment status. As a registered investment, the Trust may be subject to a special tax under Part XI of the Tax Act if it acquires or holds foreign property in excess of the limits provided in the Tax Act or enters into certain agreements to acquire shares of a corporation at a price that may differ from the fair market value of the shares at the time of acquisition. Based on Enterra's certificate as to certain factual matters and the terms of the Trust Indenture, which restrict its investments in foreign property, the Trust will not become liable for such tax.

If the Trust ceases to qualify as a mutual fund trust, the Trust may be required to pay tax under Part XII.2 of the Tax Act. The payment of Part XII.2 tax by the Trust may have material adverse tax consequences for certain unitholders.

The income of a unitholder from the trust units will be considered to be income from property for the purposes of the Tax Act. Any deduction or loss of the Trust for the purposes of the Tax Act cannot be allocated to and treated as a deduction or loss of a unitholder.

A unitholder will generally be required to include in computing income for a particular taxation year of the unitholder the portion of the net income of the Trust for a taxation year, including taxable dividends and net taxable capital gains, that is paid or becomes payable to the unitholder in that particular taxation year, whether such amount is payable in cash or in Reinvested trust units. Provided that appropriate designations are made by Commercial Trust and the Trust, such portion of the Trust's net taxable capital gains and taxable dividends, if any, as are paid or payable to a unitholder will effectively retain their character as taxable capital gains and taxable dividends, respectively, and will be treated as such in the hands of the unitholder for purposes of the Tax Act.

The amount of any net taxable capital gains designated by the Trust to a unitholder will be included in the unitholder's income under the Tax Act for the year of disposition as a taxable capital gain. See "Taxation of Capital Gains and Capital Losses" above. The non-taxable portion of net realized capital gains of the Trust that is paid or becomes payable to a unitholder in a year will not be included in computing the unitholder's income for the year. Any other amount in excess of the net income of the Trust that is paid or becomes payable by the Trust to a unitholder in a year will generally not be included in the unitholder's income for the year. However, a unitholder is required to reduce the adjusted cost base of the trust units held by such unitholder by each amount payable to the unitholder otherwise than as proceeds of disposition of trust units (except to the extent that the amount either was included in the income of the unitholder or was the unitholder's share of the non-taxable portion of the net capital gains of the Trust, the taxable portion of which was designated by the Trust in respect of the unitholder). To the extent that the adjusted cost base of a trust unit is less than zero, the negative amount will be deemed to be a capital gain of a unitholder from the disposition of the trust unit in the year in which the negative amount arises. See "Taxation of Capital Gains and Capital Losses" below.

The amount of dividends designated by the Trust to a unitholder will be subject to, among other things, the gross-up and dividend tax credit provisions for unitholders who are individuals, the refundable tax under Part IV of the Tax Act applicable to "private corporations" and "subject corporations" (as defined under the Tax Act), and the deduction in computing taxable income in respect of dividends received by taxable Canadian corporations. In general, net income of the Trust that is designated as taxable dividends from taxable Canadian corporations or as net taxable capital gains may increase an individual unitholder's liability for alternative minimum tax.

The cost to a unitholder of a trust unit will generally include all amounts paid by the unitholder for the trust unit. Reinvested trust units issued to a unitholder as a non-cash distribution of income will have a cost equal to the amount of income distributed by the issuance of such Reinvested trust units. This cost will be averaged with the adjusted cost base of all other trust units held by the unitholder as capital property in order to determine the respective adjusted cost base of each trust unit.

Upon the disposition or deemed disposition by a unitholder of a trust unit, whether on a redemption or otherwise, the unitholder will generally realize a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition exceed (or are less than) the aggregate of (i) such unitholder's adjusted cost base of the trust units disposed of, determined immediately before the disposition and (ii) any reasonable costs of disposition. A redemption of trust units in consideration for cash distributed to the unitholder in satisfaction of the Market Redemption Price, or the issuance of a Redemption Note by the Trust in satisfaction of the Market Redemption Price, will be a disposition of such trust units for proceeds of disposition equal to the cash or the principal amount of the Redemption Note, as the case may be. Where trust units are redeemed by the distribution of Series A Notes to the unitholder, the proceeds of disposition to the unitholder of such trust units will generally be equal to the fair market value of the Series A Notes so distributed less any capital gain or income realized by the Trust in connection with such redemption which has been designated by the Trust to the redeeming unitholder.

Where a unitholder that is a corporation or a trust (other than a mutual fund trust) disposes of a trust unit, the unitholder's capital loss from the disposition will generally be reduced by the amount of dividends from taxable Canadian corporations previously designated by the Trust to the unitholder, except to the extent that a loss on a previous disposition of a trust unit has been reduced by such dividends. Similar rules apply where a corporation or trust (other than a mutual fund trust) is a member of a partnership that disposes of trust units. See "Taxation of Capital Gains and Capital Losses" below.

The cost to a unitholder of any Series A Notes distributed to the unitholder by the Trust on a redemption of trust units will be equal to the fair market value of such Series A Notes at the time of distribution, excluding any accrued interest thereon. Such a unitholder will be required to include in income interest on such Series A Notes (including interest that had accrued to the date of distribution of the Series A Notes to the unitholder) in accordance with the provisions of the Tax Act. To the extent that the unitholder is required to include in income any interest that had accrued to the date of distribution of the Series A Notes, an offsetting deduction will be available in computing the unitholder's income from the Trust.

A unitholder will be required to include in income interest on the Redemption Notes in accordance with the provisions of the Tax Act.

A unitholder that is corporation that is throughout a relevant taxation year a "Canadian-controlled private corporation", as defined in the Tax Act, may be liable to pay an additional refundable tax of 6 2/3% on certain investment income, including taxable capital gains and interest.

Provided that the Trust qualifies as a "mutual fund trust" or is a "registered investment" for purposes of the Tax Act at a particular time, the trust units will be qualified investments for Exempt Plans. If the Trust ceases to qualify as a mutual fund trust and the Trust's registration as a registered investment under the Tax Act is revoked, the trust units will cease to be qualified investments under the Tax Act for Exempt Plans. Where, at the end of a month, an Exempt Plan holds trust units or other properties that are not qualified investments, the Exempt Plan may, in respect of that month, be required to pay a tax under Part XI.1 of the Tax Act.

Exempt Plans will generally not be liable for tax in respect of any distributions received from the Trust or any capital gain arising on the disposition of trust units. However, where an Exempt Plan receives trust property as a result of a redemption of trust units, some or all of such property may not be qualified investments under the Tax Act for the Exempt Plans and could, as discussed above, give rise to adverse consequences to the Exempt Plans (and, in the case of registered retirement savings plans or registered retirement income funds, to the annuitants thereunder). Accordingly, Exempt Plans that own trust units should consult their own tax advisors before deciding to exercise their redemption rights thereunder.

Based on Enterra's certificate as to certain factual matters, provided that the Trust is a "mutual fund trust" and restricts its holdings of foreign property within the limits provided under the Tax Act (30% based on cost in 2003), or the Trust is a "registered investment" within the meaning of the Tax Act (see "Taxation of the Trust" above), the trust units will not constitute foreign property for Exempt Plans, registered pension funds or plans or other persons subject to tax under Part XI of the Tax Act. Registered education savings plans are not subject to tax under Part XI of the Tax Act.

Generally, one half of any capital gain (a "taxable capital gain") realized by a unitholder or a unitholder on the disposition of capital property in a taxation year must be included in the income of the holder for the year, and one half of any capital loss (an "allowable capital loss") realized in a taxation year may be deducted from taxable capital gains realized by the holder in that year. Allowable capital losses for a taxation year in excess of taxable capital gains for that year generally may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against net capital gains realized in such years, to the extent and under the circumstances described in the Tax Act.

A corporation that is throughout a relevant taxation year a "Canadian-controlled private corporation", as defined in the Tax Act, may be liable to pay an additional refundable tax of 6 2/3% on certain investment income, including taxable capital gains realized in the particular taxation year.

Capital gains realized by an individual may give rise to a liability for alternative minimum tax.

This portion of the summary is applicable to a unitholder who, for the purposes of the Tax Act, and at all relevant times is not resident in Canada and is not deemed to be resident in Canada, does not use or hold, and is not deemed to use or hold, trust units in, or in the course of, carrying on business in Canada, and is not an insurer who carries on an insurance business in Canada and elsewhere (a "Non-Resident Holder").

The tax treatment of the Trust under the Tax Act is as generally described above under "Residents of Canada – Taxation of the Trust". If the Trust ceases to qualify as a mutual fund trust for purposes of the Tax Act, the Trust may be required to pay tax under Part XII.2 of the Tax Act. The payment of Part XII.2 tax by the Trust may have adverse tax consequences to certain unitholders.

All income of the Trust determined in accordance with the Tax Act (except taxable capital gains) paid or credited by the Trust in a taxation year to a Non-Resident Holder will generally be subject to Canadian withholding tax at a rate of 25%, subject to a reduction of such rate under an applicable income tax treaty or convention, whether such income is paid or credited in cash or in Reinvested trust units. See "Residents of Canada – Taxation of the Trust" above. Provided that certain conditions are satisfied, the rate of Canadian withholding tax may be reduced to nil in respect of amounts that are paid or credited by the Trust to a Non-Resident Holder as income of or from the Trust where the amount that can reasonably be regarded as being derived from interest that would not have been subject to Canadian withholding tax under the Tax Act had the interest been paid directly to the Non-Resident Holder instead of to the Trust.

Taxable capital gains realized by the Trust and paid or payable by the Trust in a taxation year to a Non-Resident Holder will generally be deemed to be taxable capital gains of the Non-Resident Holder from the disposition of capital property and may be subject to tax under the Tax Act. See "Taxation of Capital Gains and Capital Losses on Dispositions of Taxable Canadian Property" above.

The cost to a Non-Resident Holder of a trust unit will generally include all amounts paid by the Non-Resident Holder for the trust unit. Reinvested trust units issued to a Non-Resident Holder as a non-cash distribution of income will have a cost equal to the amount of income distributed by the issuance of such Reinvested trust units for purposes of the Tax Act. This cost will be averaged with the adjusted cost base of all other trust units held by the Non-Resident Holder as capital property in order to determine the respective adjusted cost base of each trust unit.

Upon a redemption of trust units, a Non-Resident Holder will be subject to Canadian withholding tax at a rate of 25%, subject to reduction under any applicable tax treaty or convention, of the amount that is the Non-Resident Holder's share of taxable capital gains realized by the Trust as a result of the redemption (other than taxable capital gains that are paid or payable to the Non-Resident Holder by the Trust under the Tax Act) and of any accrued interest on the Series A Notes that is transferred to the Non-Resident Holder on the redemption.

Taxable capital gains realized by the Trust on a disposition of Series A Notes to a Non-Resident Holder on a redemption of trust units, which are paid or payable by the Trust in a taxation year to a Non-Resident Holder will generally be deemed to be taxable capital gains of the Non-Resident Holder from the disposition of capital property and may be subject to tax under the Tax Act. See "Taxation of Capital Gains and Capital Losses on Dispositions of Taxable Canadian Property" below.

A Non-Resident Holder will be subject to taxation in Canada in respect of a capital gain or capital loss realized on the disposition of trust units only to the extent such units constitute "taxable Canadian property", as defined in the Tax Act, and the Non-Resident Holder is not afforded relief under an applicable income tax treaty or convention.

Trust units will normally not be taxable Canadian property at a particular time provided that (i) the Non-Resident Holder, persons with whom the Non-Resident Holder does not deal at arm's length (within the meaning of the Tax Act), or the Non-Resident Holder together with such persons, did not own or have an interest in or option in respect of 25% or more of the issued trust units at any time during the 60-month period preceding the particular time (ii) the Trust is a mutual fund trust at the time of the disposition, and (iii) the trust units are not otherwise deemed to be taxable Canadian property.

A Non-Resident Holder whose trust units constitute taxable Canadian property generally will realize a capital gain (or capital loss) on the redemption or disposition of such units equal to the amount by which the proceeds of disposition exceeds (or is less than) the aggregate of (i) such unitholder's adjusted cost base of its trust units so redeemed or disposed, determined immediately before the redemption or disposition and (ii) any reasonable costs of disposition. A redemption of trust units in consideration for cash distributed to the Non-Resident Holder in satisfaction of the Market Redemption Price, or the issuance of a Redemption Note by the Trust in satisfaction of the Market Redemption Price, will be a disposition of such trust units for proceeds of disposition equal to the cash or the principal amount of the Redemption Note, as the case may be. Where trust units are redeemed by the distribution of Series A Notes to the Non-Resident Holder, the proceeds of disposition to the Non-Resident Holder of such trust units will generally be equal to the fair market value of the Series A Notes so distributed less any capital gain or income realized by the Trust in connection with such redemption which has been designated by the Trust to the redeeming unitholder.

Where a Non-Resident Holder that is a corporation or a trust (other than a mutual fund trust) disposes of a trust unit, the Non-Resident Holder's capital loss from the disposition will generally be reduced by the amount of dividends from taxable Canadian corporations previously designated by the Trust to the unitholder, except to the extent that a loss on a previous disposition of a trust unit has been reduced by such dividends. Similar rules apply where a corporation or trust (other than a mutual fund trust) is a member of a partnership that disposes of trust units. See "Taxation of Capital Gains and Capital Losses on Dispositions of Taxable Canadian Property" below.

The cost to a Non-Resident Holder of any Series A Notes distributed to the Non-Resident Holder by the Trust on a redemption of trust units will be equal to the fair market value of such Series A Notes at the time of distribution, excluding any accrued interest thereon.

Generally, one half of any capital gain (a "taxable capital gain") realized by a Non-Resident Holder on a disposition of taxable Canadian property in a taxation year must be included in the income of the Non-Resident Holder for the year, and one half of any capital loss (an "allowable capital loss") realized by a Non-Resident Holder on a disposition of taxable Canadian property in a taxation year may be deducted from taxable capital gains realized by the Non-Resident Holder in that year. Allowable capital losses for a taxation year in excess of taxable capital gains for that year generally may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against net capital gains realized in such years, to the extent and under the circumstances described in the Tax Act.

In certain cases where a Non-Resident Holder realizes a capital gain from a disposition of property that constitute taxable Canadian property to such Non-Resident Holder, it is possible that any such capital gain may be exempt from tax for the purposes of the Tax Act by virtue of the provisions of an income tax treaty or convention between Canada and the country of residence of the Non-Resident Holder. Conversely, the amount of any capital loss resulting from the disposition of such property may not be deductible against capital gains of the Non-Resident Holder for the purposes of the Tax Act by virtue of the provisions of such income tax treaty or convention. unitholders who are Non-Resident Holders are advised to consult with their tax advisors regarding the application of any applicable income tax treaty or convention.

If a Non-Resident Holder disposes of taxable Canadian property, the Non-Resident Holder is required to file a Canadian income tax return for the taxation year in which such disposition occurs.

The following summary discusses the material United States federal income tax considerations that are generally applicable to a holder of Enterra common shares and trust units who is a citizen or resident of the United States, who is a corporation, partnership or other entity that is created or organized in or under the laws of the United States, who is subject to United States federal income tax on a net income basis with respect to Enterra common shares or who will be subject to United States federal income tax on a net income basis with respect to trust units that are acquired (a "U.S. Holder'').

This summary does not purport to be a complete description of all of the United States federal income tax considerations that may be relevant to a U.S. Holder. In particular, this summary deals only with U.S. Holders who hold Enterra common shares as a capital asset. This summary does not address the tax treatment of U.S. Holders who are subject to special tax rules. Nor does this summary discuss the United States federal income tax considerations for a partner in a partnership which holds Enterra common shares or trust units.

A U.S. holder will include in each of its taxable years its share of our items of income, gain, loss, deduction and credit and certain deductions in respect of depletion for each of our taxable years that ends within or with such U.S. holder's taxable year on its own United States federal income tax return in order to determine its liability for United States federal income tax whether or not we make any distribution to it. Such items of income, gain, loss, deduction and credit will be determined on United States federal income tax principles and will as a general matter retain their character and source as they flow through us to the holders of trust units. The use by a holder of trust units of certain of our items of deduction, loss and credit will be limited as is discussed below.

As a result, a U.S. holder whose taxable year is not the same as our taxable year and who disposes of all of its trust units after the close of its taxable year but before the end of our taxable year will be required to include in income for its then taxable year its share of more than one year of our items of income, gain, loss, deduction and credit. A U.S. Holder's share of our items of income, gain, loss, deduction and credit will, as a general matter, be its percentage interest in us of such items.

As general matter, the character and source of a U.S. holder's share of the items of the income, gain, loss, deduction and credit is determined at our level and flows through us to each such U.S. holder in determining its liability for United States federal income tax including any effect of the alternative minimum tax. Each U.S. holder should consult with its tax advisors as to the impact of holding trust units on its liability for the United States federal income tax and the alternative minimum tax. The rules as to the use of foreign income taxes as credits are complex, the following discussion is only a summary of a portion thereof, and a U.S. holder should discuss these matters with its own tax advisors.

A U.S. holder's share of our oil and gas production is treated as ordinary income subject to cost depletion. Such ordinary income is generally subject to the income tax at a maximum rate of 35 percent. Dividends that are received from a foreign corporation are currently subject to the United States federal income tax at a maximum rate of 15 percent under certain conditions. If a U.S. holder who is an individual, then any dividends received would be subject to the United States federal income tax at a maximum rate of 15 percent so long as (i) the shares in respect of which the dividends are paid have been held (subject to certain tolling rules) for more than 60 days during the 120 day period which begins 60 days before the those shares go ex-dividend, (ii) such U.S. holder is not under an obligation to make certain related payments with respect to substantially similar or related property, (iii) we are not either a foreign personal holding company, a foreign investment company or a passive foreign investment company, and (iv) we are eligible for the benefits of the income tax treaty between Canada and the United States. It is likely that the Internal Revenue Service will take the position that such holding period requirement is applied when an individual holds shares indirectly through us to the individual's holding period in trust units.

For a U.S. holder who is an individual, any long-term capital gain that is realized on the sale or other disposition of trust units (including any part of a distribution that is treated as gain on such shares that is a long-term capital gain) would be subject to tax at a maximum rate of 15 percent until the end of 2008 under current law. Each U.S. holder should discuss with its own advisor whether a person whose holding period in us is less than one year can claim such 15 percent tax rate.

As a general matter, any Canadian income taxes that are withheld from distributions are foreign income taxes that, subject to generally applicable limitations under United States law, may be used by a U.S. holder as a credit against its United States federal income tax liability or as a deduction (but only for a taxable year for which such U.S. holder elects to do so with respect to all foreign income taxes). So long as we are a partnership for United States federal income tax purposes, the provisions of Section 901(k) of the Internal Revenue Code should not apply. If we were a corporation for such purposes, then a U.S. Holder would not be able to claim the foreign tax credit with respect to any such Canadian tax that is withheld on a distribution that we made unless such U.S. holder had held the trust units for a minimum period (subject to certain tolling rules) of at least 16 days during the 30 day period beginning on the date which is 15 days before the date on which the trust units went ex-dividend with respect to such dividend or to the extent such U.S. holder is under an obligation to make related payments with respect to substantially similar or related property. It is likely that the Internal Revenue Service will take the position that the holding period requirement that is summarized in the preceding sentence is measured as to an individual partner of us in respect of any Canadian taxes paid by us in respect of dividends that we receive by the holding period in the trust units.

The limitation under United States law on foreign taxes that may be used as credits is calculated separately with respect to specific classes of income or "baskets." That is, the use of foreign taxes that are paid with respect to income in any such basket as a credit is limited to a percentage of the foreign source income in that basket. For such purposes, a U.S. holder's share of our income, gain, loss and deductions is generally in the passive basket if it holds less than 10 percent of the trust units. Its share of the dividends and the income will be from foreign sources, but the amount of foreign source income of an individual is only a fraction of the dividend income that is subject to the 15 percent maximum rate. Under rules of general application, a portion of a U.S. holder's interest expense and other expenses can be allocated to, and thereby reduce, the foreign source income in any basket.

Any gain that is recognized by a U.S. Holder on the sale of a trust unit that is recognized because a distribution thereon is in excess of basis in that security will generally constitute income from sources within the United States for U.S. foreign tax credit purposes and will therefore not increase the ability to use foreign taxes as credits.

Although we do not expect to be a passive foreign investment company, or PFIC, it will be a PFIC if either (a) 75 percent or more of its gross income in a taxable year, including the pro rata share of the gross income of any company, U.S. or foreign, in which it is considered to own 25 percent or more of the shares by value, is passive income (as defined in the pertinent provisions of the Internal Revenue Code or (b) 50 percent or more of its assets (including the pro rata share of the assets of any company in which it is considered to own 25 percent or more of the shares by value), are held for the production of, or produce, passive income. Although we believe that we are not currently a PFIC and do not expect that we will become a PFIC, there is no assurance in that regard.

If we were a PFIC, and a U.S. holder did not make an election to treat it as a qualified electing fund (there is no assurance that it will be able to make such an election) or elect to make a mark-to-market election (again, there is no assurance that it will be able to make such an election) then distributions on our stock that exceed 125 percent of the average distributions received by the U.S. holder in the shorter of the three previous taxable years or the U.S. holder's holding period for the trust units before the taxable year of distribution and the entire amount of gain that is realized by a U.S. holder upon the sale of the trust units would be subject to an additional United States income tax that approximates (and in some cases exceeds) the value of presumed benefit of a deferral of United States income taxation that was available because we are a foreign corporation.

Ownership of trust units by employee benefit plans, other tax-exempt organizations, non-resident aliens, foreign corporations, other foreign persons and regulated investment companies or mutual funds raises issues unique to those investors and, as described below, may have substantially adverse tax consequences to them.

Employee benefit plans and most other organizations exempt from federal income tax, including individual retirement accounts and other retirement plans, are subject to federal income tax on unrelated business taxable income. We are unable to provide any assurance that the income that we recognize in respect of the royalty or in respect of any of our other assets will not be unrelated business taxable income.

A regulated investment company or "mutual fund" (as such terms are used in the Internal Revenue Code) is required in order to maintain its special status under the Internal Revenue Code to derive 90 percent or more of its gross income from interest, dividends and gains from the sale of stocks or securities or foreign currency or specified related sources. A significant amount of our gross income may not be any such type of income.

We expect to furnish to each unitholder, within 90 days after the close of each calendar year, specific tax information, including a Schedule K-1, which describes the unitholder’s share of our income, gain, loss, deduction and credits for the preceding taxable year. In preparing this information, which will not be reviewed by tax counsel, we will take various accounting and reporting positions, some of which have been mentioned earlier, to determine the share of income, gain, loss and deduction. We cannot assure you that those positions will yield a result that conforms to the requirements of the Internal Revenue Code Treasury regulations or administrative interpretations of the Internal Revenue Service. Any challenge by the Internal Revenue Service could negatively affect the value of the trust units.

The Internal Revenue Service may audit our federal income tax information returns. Adjustments resulting from an Internal Revenue Service audit may require each unitholder to adjust a prior year's tax liability, and possibly may result in an audit of its return. Any audit of a unitholder's return could result in adjustments not related to our returns. Partnerships generally are treated as separate entities for purposes of federal tax audits, judicial review of administrative adjustments by the Internal Revenue Service 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 Tax Matters Partner will make some elections on our behalf and on behalf of unitholders. In addition, the Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against unitholders for items in our returns. The Tax Matters Partner may bind a unitholder with less than a one percent profits interest in us to a settlement with the Internal Revenue Service unless that unitholder elects, by filing a statement with the Internal Revenue Service, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the 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 unitholder having at least one percent interest in profits or by any group of unitholders having in the aggregate at least a five percent interest in profits. However, only one action for judicial review will go forward, and each unitholder with an interest in the outcome may participate.

A unitholder must file a statement with the Internal Revenue Service identifying the treatment of any item on its federal income tax return that is not consistent with the treatment of the item on our return. Intentional or negligent disregard of this consistency requirement may subject a unitholder to substantial penalties.

Persons who hold an interest trust units as a nominee for another person are required to furnish to us:

• the name, address and taxpayer identification number of the beneficial owner and the nominee;

• whether the beneficial owner is:

(i) a person that is not a United States person;

(ii) a foreign government, an international organization or any wholly owned agency or instrumentality of either of the foregoing; or

(iii) a tax-exempt entity;

• the amount and description of trust units held, acquired or transferred for the beneficial owner; and

• specific information including the dates of acquisitions and transfers means of acquisitions and transfers, and acquisition cost for purchases, as well as the amount of net proceeds from sales.

Brokers and financial institutions are required to furnish additional information, including whether they are United States persons and specific information on the trust units they acquire, hold or transfer for their own account. A penalty of $50 per failure, up to a maximum of $100,000 per calendar year, is imposed by the Internal Revenue Code for failure to report that information to us. The nominee is required to supply the beneficial owner of the trust units with the information furnished to us.

The Internal Revenue Code requires that "tax shelters" be registered with the Secretary of the Treasury. Although we may not be a "tax shelter" for such purposes, we have applied to register as a "tax shelter" with the Secretary of the Treasury in light of the substantial penalties that might be imposed if registration is required and not undertaken.

Issuance of a tax shelter registration number does not indicate that investment in us or the claimed tax benefits have been reviewed, examined or approved by the Internal Revenue Service.

We will supply our tax shelter registration number to you when one has been assigned to us. A unitholder who sells or otherwise transfers a trust unit in a later transaction must furnish the registration number to the transferee. The penalty for failure of the transferor of a unit to furnish the registration number to the transferee is $100 for each failure. A unitholder must disclose our tax shelter registration number on its tax return on which any deduction, loss or other benefit we generates is claimed or on which any of our income is included. A unitholder who fails to disclose the tax shelter registration number on its return, without reasonable cause for that failure, will be subject to a $250 penalty for each failure. Any penalties discussed are not deductible for federal income tax purposes.

Certain Treasury regulations require taxpayers to report specific information on Internal Revenue Service Form 8886 if they participate in a "reportable transaction." A transaction may be a reportable transaction based upon any of several factors, including the existence of book-tax differences common to financial transactions, one or more of which may be present with respect to your investment in the trust units. Investors should consult their own tax advisor concerning the application of any of these factors to an investment in the trust units. Congress is considering legislative proposals that, if enacted, would impose significant penalties for failure to comply with these disclosure requirements.

We urge each U.S. holder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, of acquiring and holding the trust units. We urge each prospective unitholder to consult tax counsel or other professional advisor with regard to those matters. Further, it is the responsibility of each unitholder to file all state, local and foreign, as well as United States federal tax returns that may be required.

We have filed with the SEC a registration statement on Form F-3 under the U.S. Securities Act with respect to the trust units described in this prospectus. This prospectus, which constitutes a part of that registration statement, does not contain all of the information set forth in that registration statement and its exhibits. For further information with respect to us and our trust units, you should consult the registration statement and its exhibits.

The Registrant’s by-laws provide the following in accordance with the Business Corporations Act (the "Act") Alberta, Canada.

"The Corporation shall indemnify a director or officer of the Corporation, a former director or officer of the Corporation or a person who acts or acted at the Corporation's request as a director or officer of a body corporate of which the Corporation is or was a shareholder or creditor, and his heirs and legal representatives to the extent permitted by the Business Corporations Act."

"Except as otherwise required by the Business Corporations Act and subject to paragraph 6, the Corporation may from time to time indemnify and save harmless any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that he is or was an employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee, agent of or participant in another body corporate, partnership, joint venture, trust or other enterprise, against expenses (including legal fees), judgments, fines and any amount actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted honestly and in good faith with a view to the best interests of the Corporation and, with respect to any criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that his conduct was lawful. The termination of any action, suit or proceeding by judgment, order, settlement or conviction shall not, of itself, create a presumption that the person did not act honestly and in good faith with a view to the best interests of the Corporation and, with respect to any criminal or administrative action or proceeding that is enforced by a monetary penalty, had no reasonable grounds for believing that his conduct was lawful."

"The provisions for indemnification contained in the by-laws of the Corporation shall not be deemed exclusive of any other rights to which any person seeking indemnification may be entitled under any agreement, vote of shareholders or directors or otherwise, both as to action in his official capacity and as to action in another capacity, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs and legal representatives of such a person."

"To the extent permitted by law, no director or officer for the time being of the Corporation shall be liable for the acts, receipts, neglects or defaults of any other director or officer or employee or for joining in any receipt or act for conformity or for any loss, damage or expense happening to the Corporation through the insufficiency or deficiency of title to any property acquired by the Corporation or for or on behalf of the Corporation or for the insufficiency or deficiency of any security in or upon which any of the moneys of or belonging to the Corporation shall be placed out or invested or for any loss or damage arising from the bankruptcy, insolvency or tortious act of any person, firm or body corporate with whom or which any moneys, securities or other assets belonging to the Corporation shall be lodged or deposited or for any loss, conversion, misapplication or misappropriation of or any damage resulting from any dealings with any moneys, securities or other assets belonging to the Corporation or for any other loss, damage or misfortune whatever which may happen in the execution of the duties of his respective office or trust or in relation thereto unless the same shall happen by or through his failure to act honestly and in good faith with a view to the best interests of the Corporation and in connection therewith to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. If any director or officer of the Corporation shall be employed by or shall perform services for the Corporation otherwise than as a director or officer or shall be a member of a firm or a shareholder, director or officer of a body corporate which is employed by or performs services for the Corporation, the fact of his being a director or officer of the Corporation shall not disentitle such director or officer or such firm or body corporate, as the case may be, from receiving proper remuneration for such services."

The undersigned Registrant hereby undertakes:

(1)    To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

1. To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

2. To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

3. To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement;

(2)    That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)    To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)    To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial Statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933 need not be furnished, provided, that the Registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933 or Item 8.A. of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

The undersigned registrant hereby undertakes that, for the purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form F-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the city of Calgary, Canada on this 21th day of June 2004.
