GENERAL DEVELOPMENTS OF OUR BUSINESS

History and Significant Acquisitions

The Enterra Arrangement

The Enterra Arrangement became effective on November 25, 2003.  Pursuant to the Enterra Arrangement, the outstanding common shares of Old Enterra were exchanged by the shareholders thereof for an aggregate of 18,951,556 Trust Units.  In addition, as part of the Enterra Arrangement, EEC issued an aggregate of 2,000,000 EEC Exchangeable Shares to former holders of Old Enterra common shares in accordance with elections made by such holders under the Enterra Arrangement.  Each EEC Exchangeable Share was exchangeable into Trust Units at any time.  On January 31, 2007, all of the then-outstanding EEC Exchangeable Shares were redeemed in exchange for Trust Units.

2004 Acquisition of Rocky Mountain Energy Corp.

On September 29, 2004 Enterra completed the acquisition of Rocky Mountain Energy Corp. by way of a plan of arrangement whereby Enterras wholly-owned subsidiary, Rocky Mountain Acquisition Corp. (RMAC), acquired all the issued and outstanding common shares of RMEC.  The transaction was valued at approximately $50.3 million.  RMEC shareholders received approximately 86% of the consideration in the form of Trust Units and RMAC Exchangeable Shares and 14% in cash.  The Trust and RMAC issued 1,946,576 Trust Units and 341,882 RMAC Exchangeable Shares, respectively.  The acquisition of RMEC added approximately 1,000 BOE/d of production together with the potential to drill over 22 additional wells.  RMAC was subsequently renamed to Enterra Production Corp. (EPC) on January 1, 2007.  On January 19, 2007 all of the then-outstanding RMAC Exchangeable Shares were redeemed in exchange for Trust Units and EPC was amalgamated with Enterra Energy Corp. (EEC) January 31, 2007.

2005 Acquisition of Rocky Mountain Gas, Inc.

On June 1, 2005, Enterra acquired 100% of the issued and outstanding shares of Rocky Mountain Gas, Inc. (RMG), an entity with natural gas properties in Montana and Wyoming.  The transaction was valued at approximately $24.0 million and was financed with 736,842 RMG Exchangeable Shares valued at $16.7 million, 275,474 Trust Units valued at $6.3 million and cash of $1.0 million. On June 1, 2006, all of the then-outstanding RMG Exchangeable Shares were redeemed for Trust Units.

2005 Acquisition of High Point Resources Inc.

On August 17, 2005 Enterra completed the acquisition of 100% of the common shares of High Point Resources Inc. through our wholly-owned subsidiary, RMAC, in exchange for 7,490,898 Trust Units and 1,407,177 RMAC Exchangeable Shares.  High Points oil and natural gas properties were predominantly in Alberta and British Columbia.  The acquisition increased Enterras natural gas production and development portfolio in addition to contributing significant tax pools to the Trust.

2006 Acquisition of Oklahoma Assets

During the first six months of 2006, Enterra acquired oil and natural gas producing assets located in Oklahoma (Oklahoma Assets).  The acquisition was completed through four closings.  The first closing occurred on January 18, 2006 and represented approximately 1,300 BOE/d of production capacity.  The second closing occurred on March 21, 2006 and represented approximately 3,700 BOE/d of production capacity.  The final two closings occurred on April 4, 2006 and April 18, 2006 and represented approximately 1,300 BOE/d of production capacity.  The assets consisted of approximately 80% natural gas and 20% light oil production and included approximately 53,000 net acres of land of which over 25,000 net acres were undeveloped.  The purchase price of US$307.6 million was paid for through the issuance of 5,685,028 Trust Units valued at $116.5 million, $181.0 million of cash and closing costs of $10.0 million.  Enterra filed a business acquisition report dated June 29, 2006 on SEDAR with respect to this acquisition.

The current and anticipated production from the Oklahoma Assets is primarily from the Hunton Group carbonate formations and is derived through a de-pressuring of the formation via water production followed by hydrocarbon production.  The Hunton Group is exploited at depths of approximately 1,500 metres using long, multi-leg horizontal wells.  Enterra operates all of its related production, gathering and water disposal facilities.  On June 27, 2006, a farm-out agreement was entered into with our US Farmout Partner to exploit the undeveloped Hunton Group prospects.  Additionally, all of the developed and undeveloped lands are overlain by the Woodford Shale, which is speculated to be a prospective shale gas target similar to the Barnett Shale in Texas.  Enterras long term plans include testing of this concept.

2006 Property Swap with JED Oil Inc.

On September 28, 2006, Enterra closed a property swap agreement with JED Oil Inc. whereby Enterra swapped certain of its interests in properties in the Ferrier area of Alberta for interests of JED in common with Enterras in East Central Alberta, the Desan area of Northeast British Columbia and the Ricinus area of Alberta.  The swap was based on independent third party engineering evaluations and was effective July 1, 2006.  The transaction also resulted in the termination of an Agreement of Business Principles between the Trust and JED whereby the Trust had a right of first refusal on properties that JED owned and JED had the ability to farm-in on the Trusts undeveloped lands.  Concurrent with the swap, the Trust settled all amounts owing to JED.

2007 Acquisition of Trigger Resources Ltd.

On April 30, 2007, Enterra acquired all of the issued and outstanding shares of Trigger Resources Ltd. (Trigger Resources).  Trigger Resources shareholders received cash consideration of $63.3 million which was funded by the issuance of $40.0 million of 8.25% convertible debentures that mature on June 30, 2012 and $29.2 million of Trust Units (4,945,000 trust units).  Trigger Resources oil and natural gas properties are located in west central and southwest Saskatchewan and, at the time of acquisition, added approximately 2,400 BOE/d (58% oil, 42% gas) to Enterras production portfolio.  The properties generally have 100% working interest with year round access and relatively low operating costs.

2007 Disposition of Non-core Assets

Enterra regularly evaluates asset acquisition and divestiture candidates.  This practice, in conjunction with Enterras debt reduction strategy, led the Trust in 2007 to review and identify assets deemed to be non-core to its ongoing operations.  Certain of these assets were then publicly marketed in the fall of 2007.  Enterra received numerous proposals for the assets marketed in addition to several unsolicited offers for non-core assets that had not been actively marketed.  During 2007 certain Princess non-operated, Willesden Green and Little Bow properties were sold.  At December 31, 2007, Enterra had entered into purchase and sale agreements for three other asset packages with gross proceeds totalling $45.9 million.  Subsequent to year end, all of these outstanding purchase and sale agreements have been closed.  Substantially all net proceeds have been applied to debt reduction of the Trust.  The Trust currently has another purchase and sale agreement for another asset package with gross proceeds of $1.6 million that is expected to close in Q2 2008.

Enterra continues to evaluate asset acquisition and divestiture opportunities as part of the ongoing management of its asset portfolio.

Equity Offerings

2005 Financings

On March 4, 2005 Enterra completed a private placement of 500,000 Trust Units at a price of US$19.00 for gross proceeds of US$9.5 million.  The funds received from this financing were used to reduce outstanding debt and for general corporate purposes.

On April 22, 2005 Enterra entered into an equity line of credit arrangement with Kingsbridge Capital Limited (Kingsbridge) whereby Kingsbridge committed to purchase up to US$100.0 million of Trust Units in various tranches at the option of the Trust.  Under the arrangement, the Trust issued 695,141 Trust Units for proceeds of $15.8 million.  The proceeds from the issuances were used to reduce outstanding debt and general corporate purposes.

On December 20, 2005 Enterra filed a prospectus supplement for the issuance of up to 950,000 Trust Units at US$16.00 per unit.  The issuances under the prospectus supplement were completed by January 13, 2006.  Enterra issued 950,000 Trust Units for proceeds of $17.8 million under this prospectus supplement.  The proceeds from this financing were used to fund capital expenditures and for general corporate purposes.

2006 Financings

On March 3, 2006 Enterra filed a prospectus supplement for the issuance of up to 1,500,000 Trust Units at US$17.25 per unit.  275,000 Trust Units were issued under this prospectus supplement for proceeds of $5.4 million.  Funds received from this financing were used for capital expenditures and for general corporate purposes.

On November 10, 2006 Enterra filed a short form prospectus for the issuance of 4,979,500 Trust Units at $8.10 per unit for proceeds of $40.3 million.  Funds received from this financing were used to partially repay Enterras then-existing bridge credit facilities.

On November 10, 2006 Enterra filed a short form prospectus for the issuance of $138,000,000 of 8% debentures convertible into Trust Units at $9.25 per unit.  The funds received from this financing were used to partially repay Enterras then-existing bridge credit facilities.  As at December 31, 2006 $57,669,000 of the convertible debentures had been converted into 6,234,483 Trust Units.

2007 Financings

On April 11, 2007 Enterra filed a preliminary short form prospectus for the issuance of up to 4,945,000 Trust Units, inclusive of the underwriters over-allotment option of 645,000 Trust Units, at a price of $5.90 per Trust Unit for gross proceeds of $29.2 million and $40.0 million of 8.25% debentures convertible into Trust Units at a price of $6.80 per Trust Unit.  The net proceeds of this issuance were used to finance the acquisition of Trigger Resources.

Implications of Tax Proposals by the Canadian Minister of Finance

On October 31, 2006, the Minister of Finance (Canada) (Finance) announced tax measures which will materially reduce the amount of cash available for distributions to the Unitholders.  It is expected that the Trust will be subject to these new rules beginning on January 1, 2011.

As noted above, the Trust could become subject to these changes before 2011 if it experiences growth, other than normal growth, before that time.  Under the December 15, 2006 guidelines, the Trust will be considered to have experienced only normal growth if its issuances of new equity (which for this purpose includes Trust Units and debt that is convertible into Trust Units, but does not include non-convertible debt) do not exceed, for each of the intervening periods set forth below, a safe harbour measured by reference to the Trust's market capitalization as of the end of trading on October 31, 2006 (measured solely by the market value of the issued and outstanding Trust Units as of that date).  The Trust's market capitalization as of October 31, 2006 was approximately $408,000,000.  The intervening periods and their respective safe harbour amounts are as follows:

(a)

November 1, 2006 to December 31, 2007  40% of the Trust's market capitalization as of October 31, 2006;

(b)

January 1, 2008 to December 31, 2008  20% of the Trust's market capitalization as of October 31, 2006;

(c)

January 1, 2009 to December 31, 2009  20% of the Trust's market capitalization as of October 31, 2006;

(d)

January 1, 2010 to December 31, 2010  20% of the Trust's market capitalization as of October 31, 2006.

The December 15, 2006 guidelines provide that these annual safe harbour amounts are cumulative, and that replacing debt that was outstanding as of October 31, 2006 with new equity, whether through a debenture conversion or otherwise, will not be considered growth for these purposes.  In addition, an issuance of new equity will not be considered growth to the extent that the issuance is made in satisfaction of the exercise by another person of a right in place on October 31, 2006 to exchange an interest in a partnership, or a share of a corporation (such as exchangeable shares), for Trust Units.

On November 21, 2006 Enterra issued Trust Units and convertible Debentures for total gross proceeds of $178.3 million.  The net proceeds from the issue combined with drawings under our Revolving and Operating Credit Facilities were used to repay in full bridge loans that had been outstanding on October 31, 2006.  The issuances will not be considered new equity for purposes of the safe harbour amounts.

On April 30, 2007 Enterra issued Trust Units and convertible debentures for total gross proceeds of $69.2 million.  The net proceeds of this issuance were used to fund the acquisition of Trigger Resources.  This issuance of new equity is within the prescribed safe harbour amounts and is not expected to be deemed as undue expansion of the Trust.

Implication of Recent Royalty Proposals by the Alberta Provincial Government

On October 25, 2007 the Alberta Provincial Government (the Province) announced revisions to its existing royalty regime for non-renewable energy resources that would be effective, if enacted, as of January 1, 2009 (the New Regime).  Specific details of the New Regime are still under review as the Province continues to consult with stakeholders including the oil and gas industry.  If the New Regime is enacted as currently written, however, Enterras initial assessment is that the royalty rates for its Alberta oil and gas production will, in aggregate, be impacted in a direct manner dependent upon commodity prices.  Asset dispositions closed in December 2007 and subsequent to year end consisted exclusively of Alberta based production and will reduce the Trusts exposure to changes in the royalty structure contemplated under the New Regime.  Royalty rates for production of the Trust from British Columbia, Saskatchewan and the United States are not impacted by the New Regime.

DESCRIPTION OF OUR BUSINESS AND PROPERTIES

Who We Are

Our portfolio of crude oil, natural gas liquids and natural gas interests is geographically diversified and split between natural gas and liquids production.  Our properties are located principally in Alberta, British Columbia, Saskatchewan and Oklahoma.  Our average production for 2007 was 12,428 BOE/d, which was comprised of 62% natural gas and 38% crude oil and natural gas liquids.

Current Focus of the Trust

Circumstances in 2007 that have resulted in the current suspension of Trust distributions are also causing a review of the key strategies of Enterra.  A primary goal for 2008 is the reduction of debt with the long term goal to improve the balance sheet.  At the same time, select capital reinvestment projects thought to have the best performance on a near term basis are being pursued and to the extent possible, production rates and reserve values are being preserved.  It is not anticipated that production and reserves values can be held flat with the current capital budget of $30.0 million for 2008.  Cost reduction at operating and overhead levels will be important to achieving both debt reduction and capital reinvestment goals.

Business Strategy During 2007

The goal of Enterra has been to generate returns for its unitholders from steady and consistent increases in reserves, production and funds from operations per trust unit.  To achieve that goal the Trust has pursued a three-point strategy as follows:

Organic Growth

The Trust currently targets investment in the large portfolio of lower-risk development opportunities it has identified within its existing asset base.  The individual nature and number of opportunities varies across the properties, but in aggregate the Trust believes they offer a means of adding reserves and production on a basis that will be accretive to unitholders and at a pace that is generally within the control of the Trust.  As a method of countering natural production declines and potentially growing reserve values, the Trust believes that investing in such projects is in the long-term interest of unitholders.

Accretive Acquisitions

Corporate and property acquisitions can be an effective means of consolidating assets, improving efficiencies in existing core areas or adding new core areas.  The ability to make material, accretive acquisitions is subject to the business environment prevailing at any particular time and the availability of capital beyond the internally generated cash flow of the Trust.

Strategic Partnerships

The Trust has actively sought to align itself with industry partners that provide access to projects that otherwise may not be available due to the nature or degree of risk involved or due to the expertise required to properly capitalize on the opportunity.

In pursuing the strategies, Enterra has sought to manage the risk to unitholders by a geographically diversified production base, by maintaining a reasonable balance between liquids and gas production, seeking high working interests, operatorship and ownership of associated infrastructure, and maintaining a multi-year inventory of lower-risk development projects.

Competitive Strengths

We believe we have identified a number of competitive strengths which will enhance the execution of our business strategy and assist us in meeting our goal of generating strong returns.  Our competitive strengths include:



- 13 -



---







Diversified Production Base

Our assets are concentrated in four areas: north east British Columbia, Alberta, Saskatchewan and Oklahoma.  While each area has different geological, production and infrastructure characteristics, in aggregate they have historically provided a stable source of production.  See Statement of Reserves and other Oil and Gas Information.

Large Portfolio of Development Projects

Our properties contain a number of potential development projects, which we believe supports our strategy of reserving a portion of funds from operations to invest in organic growth opportunities.  Currently, we estimate that there are a significant number of drilling opportunities on our approximately 277,000net acres of undeveloped land.  See Statement of Reserves and other Oil and Gas Information.

U.S. Platform Distinguishes Us From Other Canadian Oil & Gas Trusts

Based on average production in December 2007, approximately41% of our production is in the United States.  We believe that our presence in both countries, in terms of people and assets, provides us with a broader range of opportunity, improves our perspective when evaluating projects or acquisitions, and reduces our dependence on the highly competitive Canadian market.

Attractive Commodity Price Hedges

As part of our active risk management program where we hedge up to 50% of our projected gross production up to 24 months in advance, we have entered into a series of collars to reduce the impact of short-term fluctuations in crude oil and natural gas prices.  The terms of the transactions are detailed in the notes to our 2007 consolidated annual financial statements and in the associated Managements Discussion and Analysis of Financial Condition and Results of Operations.

New Experienced Management Team

Over the past year, we have made several changes to our management team which we believe has resulted in the formation of a strong, experienced and committed management team that has demonstrated its ability to identify and successfully execute our business plans.  See Corporate Governance  Directors and Officers.

Personnel

At December 31, 2007, we employed or contracted 55 office personnel and 42 field operations personnel in our Canadian operations and 25 office personnel and 25 field operations personnel in our U.S. operations for a total of 147 employees.

RISK FACTORS

Risks Related to Our Business

Volatility in oil and natural gas prices could have a material adverse effect on results of operations and financial condition, which, in turn, could affect the market price of our Trust Units or Debentures and the amount of distributions to Unitholders.

Our business, results of operations, financial condition and future growth are substantially dependent on the prevailing prices for our production.  Historically, the markets for oil and natural gas have been volatile and such markets are likely to continue to be volatile in the future.  Prices for oil and natural gas are based on world supply and demand and are subject to large fluctuations in response to relatively minor changes in supply or demand, whether the result of uncertainty or a variety of additional factors beyond our control including, without limitation, actions taken by OPEC and its adherence to agreed production quotas, war, terrorism, government regulation, social and political conditions, economic conditions, prevailing weather patterns and the availability of alternative sources of energy.  Any substantial decline in the price of oil or natural gas could have a material adverse effect on our revenues, operating income, cash flows and borrowing capacity and may require a reduction in the carrying value of our properties, planned level of spending for exploration and development and level of reserves.  No assurance can be given that prices for oil or natural gas will be sustained at levels that will enable us to operate profitably or make distributions.

We use financial derivative instruments and other hedging mechanisms to try to limit a portion of the adverse effects resulting from changes in oil and natural gas prices.  To the extent we hedge our commodity price exposure, we forego the benefits we would otherwise experience if commodity prices were to increase.  In addition, our commodity hedging activities could expose us to losses.  Such losses could occur under various circumstances, including where the other party to a hedge does not perform its obligations under the hedge agreement, the hedge is imperfect or our hedging policies and procedures are not followed.  Furthermore, it is unlikely that such hedging transactions will fully offset the risks of changes in commodity prices.

Our Revolving and Operating Credit Facilities may not provide sufficient liquidity.

Our Revolving and Operating Credit Facilities may not provide us with sufficient liquidity.  Currently, the amounts available under our Revolving and Operating Credit Facilities are not sufficient to repay our Second-Lien Credit Facility by its maturity date on November 20, 2008, and we may not be able to obtain additional financing on economic terms attractive to us, if at all.

Under the current terms of our Revolving and Operating Credit Facilities the Trust cannot use cash flow from operations to fund the required SecondLien debt repayments and convertible debenture interest repayments.  The Trust is required under the Second-Lien Credit Facility to reduce the debt to $28.0 by June 30, 2008 from its current level of $29.1 million.  Furthermore, the Trust must make interest payments on its convertible debentures of approximately $4.9 million on June 30, 2008.  There is a risk that the Trust will not be able to renegotiate these restrictions on cash under its current credit agreements, receive proceeds from asset dispositions or the issuance of new equity or new borrowings to make these required payments.

Our obligations to our lenders may have a material adverse affect on our ability to pay distributions to Unitholders.

The payment of interest and principal, and other costs, expenses and disbursements to our lenders reduces the amounts available for potential distribution to Unitholders.  Variations in interest rates and required principal repayments could result in significant changes to the amount of the funds from operations required to be applied to the debt before payment of any amounts to Unitholders.  The agreement governing our Revolving and Operating Credit Facilities provides that if we are in default of its terms, or if amounts outstanding exceed the amount of the borrowing base, our ability to make distributions to Unitholders may be restricted.



- 15 -



---





On September 17, 2007 the Trust suspended its monthly distributions in order to redirect its cash flow to the repayment of its outstanding debt.

Our assets are leveraged.  Any material change in our liquidity could impair our ability to make potential distributions to Unitholders and could adversely affect the market price of our Trust Units or Debentures.

We carry debt that is secured by our assets.  A decrease in the amount of production or the price received for it could make it difficult for us to service our debt or may cause our lenders to determine that our assets are insufficient security for the debt.  Repayment of all or a portion of outstanding amounts under our Revolving and Operating Credit Facilities may be demanded on relatively short notice.  If this occurs, we may need to obtain alternate financing.  Any failure to obtain suitable replacement financing may have a material adverse effect on our business, or adversely affect the market price of our Trust Units or Debentures.  On September 17, 2007 the Trust suspended its monthly distributions in order to redirect its cash flow to the repayment of its outstanding debt.

An inability to add additional reserves through development or acquisition could have a material adverse effect on the market price of our Trust Units or Debentures.

We do not actively explore for oil and natural gas reserves.  Instead, we add to our oil and natural gas reserves primarily through development, exploitation and acquisitions.  As a result, future oil and natural gas reserves are highly dependent on success in developing and exploiting existing properties and acquiring additional reserves.  Accordingly, if external sources of capital, including the issuance of additional Trust Units or other securities, become limited or unavailable on commercially reasonable terms, our ability to make the necessary capital investments to maintain or expand oil and natural gas reserves will be impaired. To the extent that we are required to use funds from operations to finance capital expenditures or property acquisitions, the level of funds from operations available for distribution to Unitholders will be reduced.  Additionally, we cannot guarantee that we will be successful in developing or exploiting additional reserves or acquiring additional reserves on terms that meet our investment objectives.  Without these reserve additions, our reserves will deplete and as a consequence, either production from, or the average reserve life of, our properties will decline.  Either decline may result in a reduction in the value of our Trust Units and in a reduction in cash available for potential distributions to Unitholders.

A decline in our ability to market our oil and natural gas production could have a material adverse effect on production levels or on the price received for production, which, in turn, could have a material adverse effect on the market price of our Trust Units or Debentures.

Our business depends in part upon the availability, proximity and capacity of oil and gas gathering systems, pipelines and processing facilities.  Canadian federal and provincial, as well as United States federal and state, regulation of oil and gas production, processing and transportation, tax and energy policies, general economic conditions, and changes in supply and demand could adversely affect our ability to produce and market oil and natural gas. If market factors change and inhibit the marketing of our production, overall production or realized prices may decline, which could reduce potential distributions to Unitholders.

Fluctuations in foreign currency exchange rates could have a material adverse effect on our business.

The price that we receive for a majority of our oil and natural gas is based on United States dollar denominated benchmarks, and therefore the price that we receive in Canadian dollars is affected by the exchange rate between the two currencies.  A material increase in the value of the Canadian dollar relative to the United States dollar may negatively impact net production revenue by decreasing the Canadian dollars received for a given United States dollar price.  We could be subject to unfavourable price changes to the extent that we have engaged, or in the future engage, in risk management activities related to foreign exchange rates, through entry into forward foreign exchange contracts or otherwise.

---





Distributions, if any, may be reduced during periods in which we make capital expenditures or debt repayments using cash flow.

To the extent that we use cash flow to finance acquisitions, development costs and other significant expenditures, the portion of funds from operations that is available for distribution to Unitholders will be reduced.  As a result, the timing and amount of capital expenditures may affect the amount of cash available to distribute to Unitholders.  Distributions may be reduced, or even eliminated, at times when we make significant capital or other expenditures.

The board of EEC, the administrator and principal operating subsidiary of the Trust, has the discretion to determine the extent to which funds from operations will be allocated to the payment of debt service charges as well as the repayment of outstanding debt, including under our Revolving and Operating Credit Facilities.  As a consequence, the amount of funds EEC retains to pay debt service charges or reduce debt will reduce the amount of cash available for distribution to Unitholders during those periods in which funds are so retained.

Actual reserves will vary from reserve estimates, and those variations could have a material adverse effect on the market price of the Trust Units or Debentures and distributions to Unitholders.

The reserve and recovery information contained in the Reserve Reports relating to our reserves are only estimates and the actual production and ultimate reserves from its properties may be greater or less than the estimates prepared by such firms.

The value of our Trust Units and Debentures depends upon, among other things, the reserves attributable to our properties.  Estimating reserves is inherently uncertain.  Ultimately, actual reserves attributable to our properties will vary from estimates, and those variations may be material.  The reserve figures contained herein are only estimates.  A number of factors are considered and a number of assumptions are made when estimating reserves.  These factors and assumptions include, among others:

•

historical production in the area compared with production rates from similar producing areas;

•

future commodity prices, production and development costs, royalties and capital expenditures;

•

initial production rates;

•

production decline rates;

•

ultimate recovery of reserves;

•

success of future development activities;

•

marketability of production;

•

effects of government regulation; and

•

other government levies that may be imposed over the producing life of reserves.

As much of our production is from geological formations with relatively limited long term production history (including the Jean Marie trend in northeast British Columbia and the Hunton formation in Oklahoma), actual results are more likely to vary from estimates.



- 17 -



---





Reserve estimates are based on the relevant factors, assumptions and prices on the date the relevant evaluations were prepared.  Many of these factors are subject to change and are beyond our control.  If these factors, assumptions and prices prove to be inaccurate, actual results may vary materially from reserve estimates.

In addition, the level of production from our existing properties may decline at rates greater than anticipated due to unforeseen circumstances, many of which are beyond our control.  A significant decline in production could result in materially lower revenues and cash flow and, therefore, could reduce the amount available for distributions to Unitholders.

As we expand our operations beyond conventional oil and natural gas production in Western Canada, we face new challenges and risks.

Our operations and expertise were previously focused on the production of conventional oil and gas production and development in the Western Canadian Sedimentary Basin.  In the second quarter of 2005, we acquired coal-bed methane properties in Wyoming and Montana and in the first quarter of 2006, we acquired properties in Oklahoma.  We have gained significant experience operating in these jurisdictions but we still will face operating and business challenges that we cannot at present foresee and will need to rely on local management.

Our Trust Indenture does not limit our activities to oil and gas production and development, and we could acquire other energy related assets, such as oil and natural gas processing plants or pipelines.  Expansion of our activities into new areas presents challenges and risks that we may not have faced in the past.  If we do not manage these challenges and risks successfully, results of operations and financial condition could be adversely affected.

Incorrect assessments of value at the time of acquisitions could have a material adverse effect on the market price of our Trust Units or Debentures and distributions to Unitholders.

The price we are willing to pay for reserve acquisitions is based largely on estimates of the reserves to be acquired.  Actual reserves could vary materially from these estimates.  Consequently, the reserves we acquire may be less than expected, which could adversely impact cash flows and distributions to Unitholders.  An initial assessment of an acquisition may be based on a report by engineers or firms of engineers that have different evaluation methods and approaches than those of our engineers, and these initial assessments may differ significantly from our subsequent assessments.

We may undertake acquisitions that could limit our ability to manage and maintain our business, result in adverse accounting treatment or be difficult to integrate into our business.  Any of these events could result in a material change in our liquidity, impair our ability to make distributions to Unitholders and could adversely affect the market price of the Trust Units or Debentures.

A component of our future growth depends on our ability to identify, negotiate, and acquire additional entities and assets that complement or expand our existing operations.  However we may be unable to complete any acquisitions or any acquisitions that may be completed may not enhance our business.  Any acquisitions could subject us to a number of risks, including:

---







•

diversion of managements attention;

•

inability to retain the management, key personnel and other employees of the acquired business;

•

inability to establish uniform standards, controls, procedures and policies;

•

inability to retain the acquired companys customers;

•

exposure to legal claims for activities of the acquired business prior to acquisition; and

•

inability to integrate the acquired company and its employees into our organization effectively.



The exploration, development and operation of a portion of our properties is dependent on third-parties, and their failure to perform or harm to their business could adversely affect our revenues and ultimately our distributions to Unitholders.

The exploration and development of a portion of our properties may be undertaken by industry partners and a lack of success or an inability to perform by such partners would affect our future prospects, revenues and distributions.

We still have limited experience operating properties in the United States and are reliant on the local employees and on our US Farmout partner for technical and operational support.  It is our expectation that we will gain more insight into the technical and operational characteristics of each of these properties through these relationships.  Any early termination or deterioration of the relationship with a partner, or any inability to rapidly understand the geology and production characteristics of the properties, could have a material adverse effect on the market price of our Trust Units or Debentures.

On properties where we are not the operator, we are reliant on the operator for continuing production from the property, and to some extent, the marketing of that production.  During 2007, approximately 23% of daily production was from properties operated by third-parties.  To the extent a third-party operator fails to perform its functions efficiently or becomes insolvent, our revenue may be reduced.  Third-party operators also makes estimating of future capital expenditures more difficult.

Further, the operating agreements which govern the properties not operated by us typically require the operator to conduct operations in a good and workman like manner.  These operating agreements generally provide, however, that the operator has no liability to the other non-operating working interest owners for losses sustained or liabilities incurred, except for liabilities that may result from gross negligence or wilful misconduct.

The exploration, development and exploitation of a portion of our properties is dependent on technological advancements becoming available on a timely basis.  Any failure to obtain or delay in achieving the advancements could adversely affect the market price of our Trust Units or Debentures and distributions to Unitholders.

The exploration, development and exploitation of certain of our properties on a basis that will maximize their contribution to the market value of our Trust Units or Debentures and to funds available for distribution requires that we be able to access on a timely basis technological advancements.  The effective realization of value from the Woodford shale formation in Oklahoma and coal bed methane potential in Wyoming are examples of such properties.  We may not be able to achieve those technological advancements or acquire the benefit of them from third-parties.

Delays in business operations could adversely affect our distributions to Unitholders.

In addition to the usual delays in payment by purchasers of oil and natural gas to the operators of our properties, and the delays of those operators in remitting payment to us, payments between any of these parties may also be delayed by:

•

restrictions imposed by lenders;

•

accounting delays;

•

delays in the sale or delivery of products;

•

delays in the connection of wells to a gathering system;

•

blowouts or other accidents;

•

adjustments for prior periods;

•

recovery by the operator of expenses incurred in the operation of the properties; or

•

the establishment by the operator of reserves for these expenses.

Any of these delays could reduce the amount of cash available for distribution to Unitholders in a given period and expose us to additional third party credit risks.

Changes in market-based factors may adversely affect the trading price of our Trust Units or Debentures.

The market price of our Trust Units is primarily a function of anticipated distributions to Unitholders and the value of our properties.  The market price of our Trust Units or Debentures is therefore sensitive to a variety of market-based factors, including, but not limited to, interest rates and the comparability of the Trust Units or Debentures to other similar securities.  Any changes in these market-based factors may adversely affect the trading price of the Trust Units or Debentures.

Our operations are entirely dependent on our management and the loss of key management and other personnel could negatively impact our business.

Unitholders are entirely dependent on our management with respect to the acquisition of oil and gas properties and assets, the development and acquisition of additional reserves, the management and administration of all matters relating to our oil and natural gas properties and the administration of the Trust.  The loss of the services of key individuals who currently comprise the management team could have a detrimental effect on us.

Management of the Trust may have conflicts of interest.

There are conflicts of interest to which several of our directors and officers are subject in connection with our operations.  In particular, certain of our directors and officers are involved in managerial or directorial positions with other oil and gas companies whose operations, from time to time, are in direct competition with our operations.  Additionally, certain of our directors and officers may become involved with entities which may, from time to time, provide financing to, or make equity investments in, our competitors.  See Conflicts of Interest and Interests of Management and Others in Material Transactions.

We may be unable to successfully compete for resources with other organizations in our industry.

We compete for capital, reserves, undeveloped lands, skilled personnel, access to drilling rigs, service rigs and other equipment, access to processing facilities, pipeline and refining capacity and in other respects with a substantial number of other organizations, many of which may have greater technical and financial resources than we do.  Some of these organizations not only explore for, develop and produce oil and natural gas but also carry on refining operations and market oil and other products on a worldwide basis.  As a result of these complementary activities, some of our competitors may have greater and more diverse competitive resources to draw on than we do. In addition, to the extent our Trust Units receive a lower market valuation relative to competing entities; we will be at a disadvantage in acquiring properties in competition with such entities.  Given the highly competitive nature of the oil and natural gas industry, any competitive disadvantage could adversely affect the market price of our Trust Units or Debentures and distributions to Unitholders.

The industry in which we operate exposes us to potential liabilities that may not be covered by insurance.

Our operations are subject to all of the risks associated with the operation and development of oil and natural gas properties, including the drilling of oil and natural gas wells, and the production and transportation of oil and natural gas.  These risks include encountering unexpected formations or pressures, premature declines of reservoirs, blow-outs, equipment failures and other accidents, cratering, sour gas releases, uncontrollable flows of oil, natural gas or well fluids, adverse weather conditions, pollution, other environmental risks, fires and spills.  A number of these risks could result in personal injury, loss of life, or environmental and other damage to our property or the property of others.  We cannot fully protect against all of these risks, nor are all of these risks insurable. We may become liable for damages arising from these events against which we cannot insure or against which we may elect not to insure because of high premium costs or other reasons. Any costs incurred to repair these damages or pay these liabilities would reduce funds available for distribution to Unitholders.

We may incur material costs and liabilities to comply with or as a result of health, safety and environmental laws and regulations.

The oil and natural gas industry is subject to extensive environmental regulation pursuant to local, state, provincial and federal legislation in Canada and the United States.  A breach of that legislation by us may result in the imposition of administrative, civil or criminal penalties, damages, fines, the issuance of clean up orders or the issuance of injunctions limiting or prohibiting some or all of its operations.  Strict liability may be incurred under these environmental regulations and legislation in connection with discharges or releases of petroleum hydrocarbons and wastes into the environment as a result of our operations.  In addition, legislation regulating the oil and natural gas industry may be changed to impose higher standards and potentially more costly obligations.  The 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change, known as the Kyoto Protocol, was ratified by the Canadian government in December 2002 and would require, among other things, significant reductions in greenhouse gases.  The impact of the Kyoto Protocol on us is uncertain and may result in significant additional costs for our operations.  Although we record a provision in our financial statements relating to estimated future environmental and reclamation obligations, we cannot guarantee that we will be able to satisfy our actual future environmental and reclamation obligations.

We are not fully insured against certain environmental risks, either because such insurance is not available or because of high premium costs.  In particular, insurance against risks from environmental pollution occurring over time (as opposed to sudden and catastrophic damages) is not available on economically reasonable terms.  Accordingly, our properties may be subject to liability due to hazards that cannot be insured against, or that have not been insured against due to prohibitive premium costs or for other reasons.  Any site reclamation or abandonment costs actually incurred in the ordinary course of business in a specific period will be funded out of funds from operations and therefore, will reduce the amount of funds available for distribution to Unitholders.  Should we be unable to fully fund the cost of remedying an environmental problem, we might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy.

Climate change impact

Enterra faces a variety of uncertainties related to climate change. These range from potential impacts from emissions restrictions, carbon taxes and other government policy initiatives to changes in weather patterns that may affect operations. Both the Alberta provincial government and the Canadian federal government have introduced planned legislative concepts that are intended, among other things, to drive industry towards CO2 emissions reduction and CO2 capture and sequestration in below ground geologic formations. In early 2008, the British Columbia provincial government announced its intention to introduce a carbon tax on fuels.

Although Enterra is not a large emitter of greenhouse gases, these forms of legislation may have an impact on both revenues and cost structures at a future undetermined time.

Another potential climate change impact on the Trust may result from the direct consequences of weather events. These may range from extreme cold events, to early break up in winter-only areas and unusual storms. In 2007, the Trusts Oklahoma operations suffered from all-time record rainfall amounts and later from a severe ice storm in December. Whether these conditions relate to a specific climate change trend or are just statistical anomalies is unknown.

Lower oil and gas prices increase the risk of impairment of our oil and gas property investments.

All costs related to the exploration for and the development of our oil and gas reserves are capitalized into one of two cost centers, Canada and the United States.  Costs capitalized include land acquisition costs, geological and geophysical expenditures, lease rentals on undeveloped properties and costs of drilling productive and non-productive wells and production equipment.  General and administrative costs are capitalized if they are directly related to development or exploration projects.  Proceeds from the disposal of oil and natural gas properties are applied as a reduction of cost without recognition of a gain or loss except where such disposals would result in a 20% change in the depletion rate.

Capitalized costs are depleted and depreciated using the unit-of-production method based on the estimated gross proven oil and natural gas reserves before royalties as determined by independent engineers.  Units of natural gas are converted into barrels of equivalents on a relative energy content basis.  The amounts recorded for depletion, depreciation and the asset retirement obligation are based on estimates.  We place a limit on the carrying value of our petroleum and natural gas properties, which may be depleted against revenues of future periods (the ceiling test).  The ceiling test is conducted separately for each cost center.  The carrying value is assessed to be recoverable when the sum of the undiscounted cash flows expected from the production of proved reserves, the lower of cost and market of unproved properties and the cost of major development projects exceeds the carrying value of the cost center.  When the carrying value is not assessed to be recoverable, an impairment loss is recognized to the extent that the carrying value of petroleum and natural gas properties exceeds the sum of the discounted cash flows expected from the production of proved and probable reserves, the lower of cost and market of unproved properties and the cost of major development projects.  The cash flows are estimated using expected future product prices and costs and are discounted using a risk-free interest rate.  The ceiling test calculation is based on estimates of reserves, production rates, oil and natural gas prices, future costs (including asset retirement costs) and other relevant assumptions.  By their nature, these estimates are subject to measurement uncertainty and may impact the consolidated financial statements of future periods.  The risk that we will be required to write down the carrying value of crude oil and natural gas properties increases when crude oil and natural gas prices are low or volatile.

At December 31, 2007 a provision of $26.2 million was recorded due to ceiling test impairment on the property, plant and equipment of Enterra which was the result of the fair value of the assets sold subsequent to year end being less than the book value of those properties.

While a write down does not directly affect funds from operations, the charge to earnings could be viewed unfavourably in the market or could limit our ability to borrow funds or comply with covenants contained in current or future credit agreements or other debt instruments.

Unforeseen title defects may result in a loss of entitlement to our production and reserves.

Although we conduct title reviews in accordance with industry practice prior to any purchase of resource assets, such reviews do not guarantee that an unforeseen defect in the chain of title will not arise and defeat our title to the purchased assets.  If such a defect were to occur, our entitlement to the production from such purchased assets could be jeopardized and, as a result, distributions to Unitholders may be reduced.

Aboriginal land claims.

The economic impact on us of claims of aboriginal title is unknown.  Aboriginal people have claimed aboriginal title and rights to a substantial portion of Western Canada.  We are unable to assess the effect, if any, that any such claim would have on our business and operations.

Electricity costs and water production may have an impact on operating costs.

Our Oklahoma and Alberta properties consume significant quantities of electricity to drive motors and pumps for the production of hydrocarbons and the lifting and re-injection of formation water.  The cost of electricity is a major component of lifting expense.  While we establish term purchases of electrical power at competitive rates, we cannot guarantee that changes in market conditions and contract renewals will continue to allow operating costs to remain competitive and certain of our key fields profitable.  Under these circumstances we would attempt to seek alternatives including self-generation of our own power requirements.  However, we cannot guarantee that self-generation of power using our own product as fuel as an alternative to grid power will be either profitable or acceptable to landowners or regulators.  A significant loss in profitability of key fields as a result of higher costs of electricity or lack of availability of electricity could affect future funds from operations and distributions.

The disposal of water associated with coal-bed methane production in Wyoming and Montana has been a significant concern of certain environmental groups.  Opposition by various environmental interests has resulted in significant delays to the permitting of coal-bed methane projects, particularly those on federal lands.  While we believe our projects will be developed successfully, we cannot guarantee that these will not be delayed or subject to restrictions that render them unprofitable.

Prospectivity of the Woodford shale for shale gas is not firmly established.

We believe the Woodford shale that underlies our lands in Oklahoma is prospective for shale gas.  However, while there is some minor production from the Woodford shale, a number of industry players have commented favourably on expectations for the Woodford shale and tests are currently being drilled in various locations in Oklahoma and Texas, the prospectivity of the Woodford shale for shale gas is not sufficiently established.  The play is technically complex and we cannot guarantee that the technical challenges will be overcome, or that the Woodford shale under our lands will prove economically successful.

Risks Related to the Trust Structure and the Ownership of Trust Units and Debentures

There would be material adverse tax consequences if we lost our status as a mutual fund trust under Canadian tax laws.

Generally speaking, the Income Tax Act (Canada) (the Tax Act) provides that a trust will permanently lose its mutual fund trust status (which is essential to the income trust structure) if it is established or maintained primarily for the benefit of non-residents of Canada (which is generally interpreted to mean that the majority of Unitholders must not be non-residents of Canada), unless at all times all or substantially all of the trusts property consisted of property other than certain taxable Canadian property (the TCP Exception). Based on the most recent information obtained through our transfer agent and financial intermediaries, in February 2008 an estimated 91% of our issued and outstanding Trust Units were held by non-residents of Canada (as defined in the Tax Act).  We are currently able to take advantage of the TCP Exception, and as a result, we do not currently have a specific limit on the percentage of Trust Units that may be owned by non-residents. We intend to continue to take the necessary measures in order to ensure that we continue to qualify as a mutual fund trust under the Tax Act.  However, we may not be able to take steps necessary to ensure that we maintain our mutual fund trust status.  Even if we are successful in taking such measures, these measures could be adverse to certain holders of Trust Units, particularly non-residents of Canada. The board of EEC could impose a specific limit on the number of Trust Units that could be beneficially owned by non-residents of Canada, similar to the non-resident ownership restrictions in place for other income funds in Canada, or could implement a dual-class unit structure which would effectively limit the aggregate number of Trust Units that could be owned by non-residents of Canada. Steps could be taken to ensure that no additional Trust Units are issued or transferred to non-residents, including limiting or suspending the trading of our Trust Units.

Should our status as a mutual fund trust be lost or successfully challenged by the Canada Revenue Agency, certain adverse consequences may arise for us and our Unitholders.  Some of the significant consequences of losing mutual fund trust status are as follows:

•

we would be subject to a special tax under Part XII.2 of the Tax Act of 36% of our designated income (which would not include interest on the Series Notes or the CT Notes). Payment of this tax may have adverse consequences for some Unitholders, particularly Unitholders that are non-residents of Canada and residents of Canada that are otherwise exempt from Canadian income tax;

•

Trust Units and Debentures held by non-residents of Canada would become taxable Canadian property. Non-resident holders would then be subject to Canadian tax reporting and payment requirements on any gains realized on a disposition of Trust Units or Debentures held by them;

•

the Trust Units and Debentures may no longer constitute qualified investments under the Tax Act for registered retirement savings plans (RRSPs), registered retirement income funds (RRIFs), registered education savings plans (RESPs), or deferred profit sharing plans (DPSPs) (collectively, Exempt Plans). If, at the end of any month, one of these Exempt Plans holds Trust Units or Debentures that are not a qualified investment, the plan must pay a tax equal to 1% of the fair market value of the Trust Units or Debentures at the time the Trust Units or Debentures were acquired by the Exempt Plan. An RRSP or RRIF holding Trust Units or Debentures that are not a qualified investment would be subject to taxation on income attributable to the Trust Units or Debentures, including the full amount of any capital gain from a disposition of the Trust Units or Debentures. If an RESP holds Trust Units or Debentures that are not a qualified investment, it may have its registration revoked by the Canada Revenue Agency; and

•

we would cease to be eligible for the capital gains refund mechanism available under the Tax Act.

Changes in tax and other legislation may adversely affect Unitholders.

Income tax laws, other legislation or government incentive programs relating to the oil and gas industry, such as the treatment of mutual fund trusts and resource allowance, may in the future be changed or interpreted in a manner that adversely affects us and our Unitholders.  Tax authorities having jurisdiction over us or our Unitholders may disagree with the manner in which we calculate our income for tax purposes or could change their administrative practices to our detriment or the detriment of our Unitholders.

On March 23, 2004, the Canadian federal government announced proposed changes to the Tax Act, which would have effectively eliminated, over a period of time, the TCP Exception currently relied on by most oil and gas trusts to maintain their mutual fund trust status. However, as the proposed changes only affected mutual fund trusts that held contractual oil and gas royalties, the proposals would not have had a direct impact on us. In response to submissions from and discussions with stakeholders, the Canadian federal government suspended the implementation of those proposed amendments.

On October 31, 2006, the Minister of Finance (Canada) (Finance) announced tax measures which will materially reduce the amount of cash available for distributions to the Unitholders.  It is expected that the Trust will be subject to these new rules beginning on January 1, 2011.

As noted above, the Trust could become subject to these changes before 2011 if it experiences growth, other than normal growth, before that time.  Under the December 15, 2006 guidelines, the Trust will be considered to have experienced only normal growth if its issuances of new equity (which for this purpose includes Trust Units and debt that is convertible into Trust Units, but does not include non-convertible debt) do not exceed, for each of the intervening periods set forth below, a safe harbour measured by reference to the Trust's market capitalization as of the end of trading on October 31, 2006 (measured solely by the market value of the issued and outstanding Trust Units as of that date).  The Trust's market capitalization as of October 31, 2006 was approximately $408,000,000.  The intervening periods and their respective safe harbour amounts are as follows:

(a)

November 1, 2006 to December 31, 2007  40% of the Trust's market capitalization as of October 31, 2006;

(b)

January 1, 2008 to December 31, 2008  20% of the Trust's market capitalization as of October 31, 2006;

(c)

January 1, 2009 to December 31, 2009  20% of the Trust's market capitalization as of October 31, 2006;

(d)

January 1, 2010 to December 31, 2010  20% of the Trust's market capitalization as of October 31, 2006.

The December 15, 2006 guidelines provide that these annual safe harbour amounts are cumulative, and that replacing debt that was outstanding as of October 31, 2006 with new equity, whether through a debenture conversion or otherwise, will not be considered growth for these purposes.  In addition, an issuance of new equity will not be considered growth to the extent that the issuance is made in satisfaction of the exercise by another person of a right in place on October 31, 2006 to exchange an interest in a partnership, or a share of a corporation (such as exchangeable shares), for Trust Units.

While these guidelines are such that it is unlikely they would affect the Trust's ability to raise the capital required to maintain and grow its existing operations in the ordinary course during the transition period, they could adversely affect the cost of raising capital and the Trust's ability to undertake more significant acquisitions.

It is not known at this time if or when the October 31 Proposals will be enacted by Parliament or whether the October 31 Proposals will be enacted in the form currently proposed.

There is no assurance that the Canadian federal government will not introduce other changes to the Tax Act directed at non-resident ownership which, given our level of non-resident ownership, may result in us losing our mutual fund trust status or could otherwise detrimentally affect us and the market price of our Trust Units.

The incurrence of tax by the Operating Subsidiaries could have a material adverse effect on our ability to pay distributions to Unitholders.

Our Operating Subsidiaries are subject to taxation in their respective taxation years on their respective taxable incomes for the year.  Our Operating Subsidiaries intend to deduct, in computing their income for tax purposes, the full amount available for deduction in each year associated with their income tax resource pools, undepreciated capital costs (UCC) and non-capital losses, if any.  If there are not sufficient resource pools, UCC, non-capital losses carried forward, and interest to shelter the income of our Operating Subsidiaries, then cash taxes would be payable.  In addition, there can be no assurance that taxation authorities will not seek to challenge the amount of resource pools, non-capital losses or interest expense relating to the Series Notes.  If such a challenge were to succeed, it could materially adversely affect the amount of cash available for distribution to Unitholders and the market value of our Trust Units.

The cash available for distribution to Unitholders is ultimately sourced from our Operating Subsidiaries, some of which are in the United States and, as a result, subject to U.S. taxation.  The Operating Subsidiaries that are subject to income taxation in the United States intend to deduct the full amount available in respect of depletion, depreciation, interest or other allowances under applicable law to reduce taxable income of such Operating Subsidiaries. There can be no assurances, however, that the taxation authorities of the United States will not challenge the amount of such deductions.  If such a challenge were to succeed it could materially adversely affect the amount of cash available for distribution to Unitholders.  Changes to the income tax law in the United States, changes to tax regulations in the United States, or changes in the interpretation or application of such law or regulations may result in increased taxation of funds generated in the United States and may adversely affect distributions to Unitholders and the market value of the Trust Units.

Interest and dividends that we receive from our Operating Subsidiaries in the United States will be subject to United States withholding taxes the amount of which will be determined under applicable law, income tax treaties and regulations.  In this regard, the United States Treasury Department has announced its intention to renegotiate one of the income tax treaties upon which we rely for a reduction in withholding taxes on distributions from our Operating Subsidiaries in the United States.  Changes in the applicable law, income tax treaties or regulations or in the application or interpretation thereof may increase such withholding taxes and may adversely affect distributions to Unitholders.

Unitholders may be required to pay taxes even if they do not receive any cash distributions.

Interest on the Series Notes and the CT Notes accrues at the Trust level for income tax purposes whether or not actually paid.  Our Trust Indenture provides that an amount equal to the taxable income of the Trust will be payable each year to Unitholders in order to reduce the Trusts taxable income to zero.  Our Trust Indenture provides that where, in a particular year, the Trust does not have sufficient available cash to distribute such an amount to the Unitholders, additional Trust Units will be distributed to Unitholders in lieu of cash payments.  Unitholders will generally be required to include an amount equal to the fair market value of those Trust Units in their taxable income, notwithstanding that they do not directly receive a cash payment.

United States Unitholders may be limited in their ability to use the Canadian withholding tax as a credit against United States federal income tax and in their ability to claim the effect of certain other favourable United States income tax provisions.

We expect that the Trust will be classified for United States federal income tax purposes as a partnership and not as a corporation. As a result, a citizen of the United States and each other person who is subject to United States federal income tax on a net income basis with respect to the Trust Units (each such person is referred to herein as a U.S. Holder) will generally include its share of the income, gain, loss, deduction and credit of the Trust on its United States federal income tax return in determining its liability for the United States federal income tax.

The Canadian income taxes that are withheld (currently at a 15 percent rate) from a distribution to a U.S. Holder on a Trust Unit may be deducted or, subject to limitations, used as a credit for United States federal income tax purposes. 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. Special rules apply in determining the foreign tax credit limitation with respect to dividends that are subject to the 15 percent rate (discussed below).  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.

For a U.S. Holder who is a non-corporate Unitholder, its share of the Trusts dividend income from its Canadian subsidiaries received before January 1, 2011 should be subject to United States federal income tax at a maximum rate of 15 percent provided that, among other things, (a) that the payor of the dividend is not classified as a PFIC during the taxable year in which such distribution is paid or the preceding taxable year, (b) that the U.S. Holder has satisfied certain holding period requirements, and (c) that the U.S. Holder has not made an election to treat the dividend as investment income for purposes of the investment interest deduction rules. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. If the rate reduction is not applicable, the dividends would be subject to United States federal income taxation at ordinary income tax rates.

Each such U.S. Holder should discuss the effect of the limitations on the use of such Canadian taxes as a credit (including the effect of any ability to obtain a refund of such Canadian withholding tax in certain circumstances) and the limitations on obtaining the favourable United States federal rate reduction with its own advisers.

United States Unitholders who are generally tax exempt under United States law may recognize unrelated business taxable income (which is subject to United States federal income tax) in respect of their Trust Units.

Individual retirement accounts, other employee benefit plans and certain organizations that are generally exempt from United States federal income tax are subject to United States federal income tax on unrelated business taxable income, such as certain income from debt financed property, to the extent that such unrelated business taxable income for a taxable year is in excess of $1,000. The Trust has in the past and may in the further incur debt the proceeds of which are invested in stock of EEC or another corporation. In that event, the dividends that the Trust receives from such corporation (which flow through to the holders of Trust Units while the Trust is a treated as a partnership for United States federal income tax purposes) will be unrelated business taxable income.

Such an individual retirement account or other tax exempt organization will generally also be subject to Canadian withholding tax on distributions that the Trust makes and will as a general matter be able to use all or a portion of that Canadian withholding tax as a credit against the United States federal income tax for which it is liable on any unrelated business taxable income in accordance with applicable law and with due regard to the applicable restrictions thereon. Such Canadian income tax will not as a general matter reduce or otherwise affect the Untied States federal income taxation of distributions that an individual retirement account or other employee benefit plans makes to its beneficiary or beneficiaries.

United States Unitholders may be subject to passive foreign investment company rules.

Although we do not expect that any of the Trusts subsidiaries that are corporations for United States federal income tax purposes (or the Trust if it were to be a corporation for such purposes) is or has been a passive foreign investment company, or PFIC, there is no assurance in that regard.

A foreign corporation is, as a general matter, 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 certain partially owned (whether directly or indirectly) corporations, is passive income (as defined in the pertinent provisions of the Code) or (b) 50 percent or more of its assets (including the pro rata share of the assets of any such partially owned subsidiary) are held for the production of, or to produce, passive income.

If the Trust or any of its subsidiaries were a PFIC, then a U.S. Holder who did not make an election to treat such corporation as a qualified electing fund (there is no assurance that it will be able to make such an election) would pay United States federal income tax on any excess distributions in respect of  the PFIC stock (even if such U.S. Holder did not own stock in the PFIC directly) is allocated rateably over the U.S. Holders holding period. The amounts allocated to the taxable year of the excess distribution and to any year before the relevant stock interest became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to United States federal income taxation at the highest rate in effect for individuals or corporations in such taxable year, as appropriate, and an interest charge would be imposed on the amount allocated to that taxable year. Distributions made in respect of the relevant PFIC stock interest during a taxable year (including any gain realized on the sale or other disposition of the PFIC stock, even if the cash proceeds thereof were not received) will be an excess distribution to the extent they exceed 125 percent of the average of the annual distributions in respect of said stock interest received by the U.S. Holder during the preceding three taxable years or the U.S. Holders holding period, whichever is shorter. Moreover, any non-corporate Unitholder who is a U.S. Holder would not be entitled to the 15 percent maximum rate of Untied States federal income tax on any dividend that is received in respect of the stock in any such PFIC.

U.S. Holders are urged to consult their own tax advisors regarding the United States federal income tax consequences of classification as a PFIC of any corporation in which the Trust owns an interest (or the Trust) and of the consequences of such classification.

United States and other non-resident Unitholders may be subject to additional taxation.

The Tax Act and the tax treaties between Canada and other countries may impose additional withholding or other taxes on the cash distributions or other property paid by the Trust to Unitholders who are not residents of Canada, and these taxes may change from time to time.  For instance, since January 1, 2005, a 15 percent withholding tax is applied to return of capital portion of distributions made to non-resident Unitholders.

The ability of United States and other non-resident investors to enforce civil remedies may be limited.

The Trust is a trust organized under the laws of Alberta, Canada, and EECs principal offices are in Canada.  Most of our directors and officers are residents of Canada and most of the experts who provide services to us (such as its auditors and some of its independent reserve engineers) are residents of Canada, and all or a substantial portion of their assets and the assets of the Trust are located within Canada.  As a result, it may be difficult for investors in the United States or other non-Canadian jurisdictions (a Foreign Jurisdiction) to effect service of process within such Foreign Jurisdiction upon such directors, officers and representatives of experts who are not residents of the Foreign Jurisdiction or to enforce against them judgement of courts of the applicable Foreign Jurisdiction based upon civil liability under the securities laws of such Foreign Jurisdiction, including United States federal securities laws or the securities laws of any state within the United States.  In particular, there is doubt as to the enforceability in Canada against EEC or any of its directors, officers or representatives of experts who are not residents of the Untied States, in original actions or in actions for enforcement of judgments of United States courts of liabilities based solely upon the Untied States federal securities laws or the securities laws of any state within the United States.

Rights as a Unitholder differ from those associated with other types of investments.

The Trust Units do not represent a traditional investment in the oil and natural gas sector and should not be viewed by investors as shares in the Trust or the Trust Subsidiaries. The Trust Units represent an equal fractional beneficial interest in the Trust and, as such, the ownership of the Trust Units does not provide Unitholders with the statutory rights normally associated with ownership of shares of a corporation, including, for example, the right to bring oppression or derivative actions. The unavailability of these statutory rights may also reduce the ability of Unitholders to seek legal remedies against other parties on the Trusts behalf.

The Trust Units are also unlike conventional debt instruments in that there is no principal amount owing to Unitholders. The Trust Units will have minimal value when reserves from our properties can no longer be economically produced or marketed. Unitholders will only be able to obtain a return of the capital they invested during the period when reserves may be economically recovered and sold. Accordingly, cash distributions do not represent a yield in the traditional sense as they represent both return of capital and return on investment and the distributions received over the life of the investment may not meet or exceed the initial capital investment.

The limited liability of Unitholders of the Trust is uncertain.

Notwithstanding the fact that Alberta (the Trusts governing jurisdiction) has adopted legislation purporting to limit Unitholder liability, because of uncertainties in the law relating to investment trusts, there is a risk that a Unitholder could be held liable for obligations of the Trust in respect of contracts or undertakings which the Trust enters into and for certain liabilities arising otherwise than out of contracts including claims in tort, claims for taxes and possibly certain other statutory liabilities. Although every written contract or commitment of the Trust must contain an express disavowal of liability of the Unitholders and a limitation of liability to Trust property, such protective provisions may not operate to avoid Unitholder liability. Notwithstanding attempts to limit Unitholder liability, Unitholders may not be protected from liabilities of the Trust to the same extent that a shareholder is protected from the liabilities of a corporation. Further, although the Trust has agreed to indemnify and hold harmless each Unitholder from any costs, damages, liabilities, expenses, charges and losses suffered by the Unitholder resulting from or arising out of that Unitholder not having limited liability, the Trust cannot guarantee that any assets would be available in these circumstances to reimburse Unitholders for any such liability.  There can be no assurance that the Alberta legislation purporting to limit Unitholder liability eliminates the risk that a Unitholder could be held liable for obligations of the Trust, and the legislation does not affect liability with respect to any act, default, obligation or liability that arose prior to July 1, 2004.

The cash redemption rights of Unitholders are limited.

Unitholders have a right to require the Trust to repurchase their Trust Units, which is referred to as a redemption right. It is anticipated that the redemption right will not be the primary mechanism for Unitholders to liquidate their investment. The Trusts obligation to pay cash in connection with redemption is subject to limitations. Any securities, which may be distributed in specie to Unitholders in connection with a redemption, may not be listed on any stock exchange and a market may not develop for such securities. In addition, there may be resale restrictions imposed by law upon the recipients of the securities pursuant to the redemption right.

There may be future dilution.

One of our objectives is to continually add to our reserves through acquisitions and through development. Since at present we do not reinvest the majority of our cash flow, our success is, in part, dependent on our ability to raise capital from time to time by selling additional Trust Units. Unitholders will suffer dilution as a result of these offerings if, for example, the cash flow, production or reserves from the acquired assets do not reflect the additional number of Trust Units issued to acquire those assets. Unitholders may also suffer dilution in connection with future issuances of Trust Units to effect acquisitions.

Unitholders will also suffer dilution as a result of the conversion of any of the Trusts Debentures, or if the Trust redeems outstanding Debentures for Trust Units or satisfies the obligation to pay interest on the Debentures by issuing additional Trust Units.  See Capital Structure  Description of Debentures.

Prior distributions are not reflective of future distributions.

Our historical distributions are not reflective of future distributions.  Future distributions will be subject to review by, and are in the discretion of, the board of EEC. On July 18, 2006, the board of EEC determined to reduce the Trusts target payout ratio range to 60% to 70% of funds from operations. On January 19, 2007, the board of EEC announced a cash distribution of US$0.06 per Trust Unit in respect of January 2007 production, a reduction from the distribution of US $0.12 per Trust Unit paid in each of the prior six months, as a result of significantly weaker commodity prices, capital market uncertainty resulting from the tax changes proposed by the Canadian government, and early conversion of Debentures to Trust Units.  On September 17, 2007 the Trust suspended its monthly distributions in order to redirect its cash flow to the repayment of its outstanding debt.

The actual amounts distributed, if any, will be based on the circumstances as they exist at the time and will be subject to a number of factors, many of which are beyond our control including, without limitation, the outlook for commodity prices and other macro-economic factors, the availability and cost of equity and debt financing, the size and nature of the prospects and opportunities available to us, and our financial position and commitments.

There may not always be an active trading market for the Trust Units and Debentures.

While there is currently an active trading market for the Trust Units in the United States and Canada and for the Debentures in Canada, there are no assurances that an active trading market will be sustained.

STATEMENT OF RESERVES DATA AND OTHER OIL AND GAS INFORMATION

Disclosure of Reserves Data

The reserves data set forth below (the Reserves Data) is based upon evaluations conducted by McDaniel with an effective date of December 31, 2007 contained in the McDaniel Report, by Haas with an effective date of December 31, 2007 contained in the Haas Report and by MHA with an effective date of January 1, 2008 contained in the MHA Report.  The Reserves Data summarizes our oil, NGL and natural gas reserves and the net present values of future net revenue for these reserves using constant prices and costs and forecast prices and costs.  The McDaniel, Haas and MHA Reports have been prepared in accordance with the standards contained in the COGE Handbook and the reserve definitions contained in NI 51-101.  Information not required by NI 51-101 has been presented to provide continuity and additional information which we believe is important.  We engaged McDaniel, Haas and MHA to provide an evaluation of our proved and proved plus probable reserves.

At December 31, 2007 our reserves were in Canada, specifically, in the provinces of Alberta, British Columbia, Saskatchewan and Manitoba, and in the United States, specifically in the states of Wyoming and Oklahoma.  McDaniel reviewed the reserves in Canada, Haas reviewed the reserves in Oklahoma and MHA reviewed the reserves in Wyoming.

All evaluations and reviews of future net cash flow are stated prior to any provision for interest costs or general and administrative costs and after the deduction of estimate future capital expenditures for wells to which reserves have been assigned.  It should not be assumed that the estimated future net cash flow shown below is representative of the fair market value of our properties.  There is no assurance that such price and cost assumptions will be attained, and variances could be material.  The recovery and reserve estimates of crude oil, NGL and natural gas reserves provided herein are estimates only and there is no guarantee that the estimated reserves will be recovered.  Actual crude oil, NGL and natural gas reserves may be greater than or less than the estimates provided herein.

Oil and Natural Gas Reserves and Net Present Value of Future Net Revenue

The tables below are summaries of our oil, NGL and natural gas reserves and the net present value of future net revenue attributable to such reserves as evaluated by McDaniel, Haas and MHA based on constant and forecast price and cost assumptions.  The tables summarize the data contained in the McDaniel, Haas and MHA Reports.  Gross reserves include royalty interests.  The data may contain slightly different numbers than the reports due to rounding.  Additionally, the numbers in the tables may not add exactly due to rounding.

The McDaniel, Haas and MHA Reports are based on certain factual data supplied by us and on McDaniels, Haas and MHAs opinions of reasonable practice in the industry.  The extent and character of ownership and all factual data pertaining to our petroleum properties and contracts (except for certain information residing in the public domain) were supplied by us to McDaniel, Haas and MHA and were accepted without any further investigation.

Undeveloped Reserves

Our undeveloped reserves were estimated by McDaniel and Haas in accordance with standards and procedures in the COGE Handbook and reserve definitions in NI 51-101. In general, undeveloped reserves are reserves scheduled to be developed within the next couple of years.

We have proved and probable undeveloped reserves in Canada and Oklahoma.  In Canada there are proved undeveloped reserves assigned to the Primate, Princess, Ricinus, Halkirk, Desan and the Cummings Y Unit assets.  Canadian proved undeveloped reserves of 2.5 Bcf of natural gas and 18.42 Mbbl of NGL and 302.3 Mbbl of oil (737 mboe) represent 7% of the total Canadian proved reserves on a boe basis. In 2007 we developed 332.2 mboe of proved plus probable reserves with drilling. In Desan, 6 development wells are planned for 2008/2009 to develop proved plus probable reserves of 5.6 Bcf and 29.9 Mbbl of NGLs.  In the Cummings Y Unit, continued development and optimization of the water flood will develop 83.9 Mbbl with an additional 83.9 Mbbl of probable reserves.  Four undeveloped locations have been identified in the Princess asset with proved plus probable undeveloped reserves of 224.1 mbbl of oil.  The Halkirk asset has one proved undeveloped location and one probable undeveloped location, both follow up locations to the successful well drilled in 2007.  These Halkirk and Princess locations are to drilled in the 2008 and 2009. A deep gas proved undeveloped location has been identified in our Ricinus Leduc asset with proved plus probable reserves of 4.0 BCF.  We plan to drill this well in 2008. The finalization of the new Alberta royalty regime may impact the timing of drilling this well and the reserve classification.

In Oklahoma, there are proved undeveloped reserves of 8.2 Bcf of natural gas and 127 Mbbl of oil representing 14% of the total Oklahoma proved reserves and probable undeveloped reserves of 5.9 Bcf of natural gas and 145.5 Mbbl of oil representing 45% of the total probable reserves.  The planned development well drilling program of 25 to 35 wells per year for the next couple of years is anticipated to develop these reserves. The 2007 19 well drilling program added 6.5 BCF and 110.9 mbbl of oil of proved plus probable reserves

Significant Factors or Uncertainties Affecting Reserves Data

The process of estimating reserves is complex.  It requires significant judgments and decisions based on available geological, geophysical, engineering, and economic data.  These estimates may change substantially as additional data from ongoing development activities and production performance becomes available and as economic conditions impacting oil and gas prices and costs change.  The reserve estimates contained herein are based on current production forecasts, prices, royalty rates and economic conditions. McDaniel, Haas and MHA, independent engineering firms, evaluate our reserves.

The Alberta government has proposed a new royalty regime but due to the uncertainties and lack of sufficient details to determine royalties for some product types the 2007 year end reserve report was prepared using the existing royalty regime.  The Canadian independent evaluation firms developed common high and low sensitivity cases to reflect the potential range of impact of the new royalty regime. The estimated impact to Enterras proved plus probable future net present value at 10 % is estimated at less than 3% reduction in net present value based on those sensitivity cases.

Although every reasonable effort is made to ensure that reserve estimates are accurate, reserve estimation is an inferential science.  As a result, the subjective decisions, new geological or production information and a changing environment may impact these estimates.  Revisions to reserve estimates can arise from changes in year-end oil and gas prices, and reservoir performance.  Such revisions can be either positive or negative.

Future Development Costs

The table below sets out the development costs deducted in the estimation of future net revenue attributable to proved reserves (using both constant prices and costs and forecast prices and costs) and proved plus probable reserves (using forecast prices and costs only).  Note: all future development costs are associated with Canadian assets; there are no future development costs associated with our U.S. assets.

We estimate that our internally generated cash flow will be sufficient to fund the future development costs disclosed above.  We typically have available three sources of funding to finance our capital expenditure program: internally generated cash flow from operations, debt financing when appropriate and new equity issues, if available on favourable terms.

We expect to fund our total 2008 capital program with internally generated cash flow.

Oil and Gas Properties

Our core areas include a variety of assets in Western Canada in the provinces of British Columbia, Alberta and Saskatchewan.  In Alberta, the major producing fields are: Clair, Sylvan Lake, Provost-Alliance-Wainwright, Princess, Ricinus, Ferrier and Lochend.  In northeast British Columbia we have a significant producing area at Desan and in west-central Saskatchewan we have production in the Primate and Liebenthal pools.  In the United States our significant producing assets are located in Grant, Lincoln and Logan counties in Oklahoma.  We also have an inventory of minor producing assets, minor royalty interests, and various prospects of an exploitation and exploration nature on undeveloped lands in Alberta, British Columbia, Saskatchewan, Wyoming, Montana and Oklahoma, the development of which could significantly increase the size of our existing production and reserve base.

In late 2007 Enterra divested its interest in its non operated properties in the Princess area and in the first quarter of 2008 we divested our interest in the Sylvan Lake, Lochend, Ferrier, and Ricinus operated properties to reduce bank debt.

Northeast British Columbia

Our northeast British Columbia assets consist of our producing property in Desan and our undeveloped properties at Kotcho and Peggo-Pesh.

Desan

The Desan property is located 75 miles northeast of Fort Nelson, British Columbia in the gas producing greater Sierra area.  The primary producing zone is the Jean Marie formation.  This regional carbonate has historically been the target for sweet dry gas and provides very good initial production and a long life of slow decline ideally suited to predictable cash flow.  Although the Jean Marie is regionally gas charged the best reserves are discovered through detailed geological and geophysical analysis, pinpointing areas of secondary porosity associated with structures.  The Jean Marie, at 1,300 m (4,250 feet), is best exploited using under-balanced drilling technology in horizontal wells.

Enterra has acquired 45 square kilometres (17 square miles) of 3D seismic and 61 kilometres (38 miles) of trade 2D seismic.  Based upon our technical review of this information we re-entered a poorly performing well and turned it into a successful gas producer by drilling to a new target zone.  We plan to exploit this knowledge by pursuing a multi-well drilling program during the 2008/2009 winter drilling season.

In late 2007 Enterras undeveloped Sierra property was divested to a third party in exchange for their Gross Overriding Riding Royalty on our Desan production plus cash consideration. This transaction will enhance the long term value of the property and provide additional development opportunities.  The average production for December 2007 was 3.3 mmcf/d natural gas and 27 bbls/d of crude oil and NGL from a total of 23 wells.

McDaniel assigned total proved plus probable reserves of 20.6 Bcf of natural gas and 109 Mbbl of NGL to the Desan property, as of December 31, 2007.

Western Alberta

In western Alberta, Enterras properties range from deep, high-rate foothills sour gas wells in Ricinus to mid-depth oil wells at Clair, Sylvan Lake, Lochend and Ferrier.  In late 2007 Enterra divested its interest in its non operated properties in the Princess area and in the first quarter of 2008 we divested our interest in our  Sylvan Lake, Lochend, Ferrier,  and  Ricinus operated  properties to reduce bank debt.

Clair

The Clair property is located 7 miles north of Grande Prairie, Alberta.  Our assets include a 100% working interest in 3,040 acres of land, 19 producing oil wells, 7 injection wells and an oil treating facility.  Gas is conserved and processed at the Tusk Energy Sexsmith gas plant and the oil is delivered into the Pembina Peace Pipeline System.

Production is primarily from the Doe Creek (Dunvegan) formation with a small amount of gas production from the Charlie Lake and Halfway formations. Production is light, 41°API gravity crude oil and solution gas from the Doe Creek oil pool.  This pool is being water flooded to maximize recovery. There is also gas production from one Charlie Lake gas well.  At December 31, 2007 there were 19 oil wells and one gas well producing a combined 765 bbl/d of oil and 850Mcf/d of raw solution gas on a working interest basis before royalties.  Enterras technical team has initiated several studies to optimize the efficiency of the water flood and to extend the pool boundaries.  The recommendations from this study will be implemented in 2008 and 2009.

McDaniel assigned proved plus probable reserves to the Doe Creek A (Dunvegan) pool of 692 Mbbl of crude oil, 831 Mmcf of gas and 54 Mbbl of NGL, as of December 31, 2007.  Included in the total net proved reserves of Clair are reserves assigned to the 13-07-073-5W6 Charlie Lake/ Halfway gas well of 159 Mmcf of gas and 10 Mbbl of NGL.

Ricinus

Ricinus is located in the Rocky Mountain foothills, 80 miles northwest of Calgary. At Ricinus, Enterra is 50% owner of a deep (2,800 m 9,200 feet) high-rate Leduc reef sour gas well that has steady gross production of 10 mmcf/d.  This well has the capability to produce at higher rates but has been limited to maximize the value of the asset. After evaluating our 3D seismic information over the reef, Enterra has entered into discussions with our partner to further develop the pool.  Timing of this development is dependent on the Alberta Government final Alberta Deep Gas Royalty Regime and results of the partner discussions.

McDaniel assigned proved plus probable gas reserves of 6.1 Bcf of natural gas to the producing well.

Eastern Alberta

Provost-Alliance-Wainwright, Alberta

The Provost-Alliance-Wainwright producing area is located near Provost, Alberta. Major areas within the package are Alliance, Sounding Lake, Halkirk, Monitor, Provost Cummings Y Unit and Wainwright. We currently have 371 producing oil and gas wells in this area.

Production is obtained primarily from the Dina, Cummings and Belly River formations. Average production for December, 2007 was 1,010 bbl/d of oil and NGL and 1,000 Mcf/d of gas on a working interest basis before royalties.  In order to increase production and lower operating costs, we have and continue to optimize the well pumping systems and upgrade or consolidate oil batteries to handle higher volumes of total fluid and injection water.  Solution gas is currently conserved at most of the oil batteries.

While these pools are mature, detailed geologic and engineering studies have identified significant potential for increases in both production and reserves through more efficient secondary recovery and exploitation of bypassed pay zones.  These studies are ongoing and will be put into practice in 2008.

McDaniel assigned proved plus probable reserves in the Provost-Alliance-Wainwright area of 2,368 Mbbl of oil 2,027 Mmcf of natural gas and 33 Mbbl of NGL, as of December 31, 2007.

Princess

Princess is located 100 miles southeast of Calgary.  The primary production is crude oil (27o API) from the Pekisko formation, a porous carbonate.  Much of Enterras land is covered by 3D seismic, and detailed geological and geophysical studies have outlined new development drilling opportunities which we plan to drill during 2008 and 2009.  In addition, significant potential lies in the Glauconite and Sunburst formations.  At year end 2007, Enterra had 20 wells in the Princess area and produced 293 bbl/d of crude oil and NGL and 0.52 mmcf/d of natural gas.

In late 2007 Enterra divested its non-operated Princess holdings to its partner.

McDaniel assigned total proved plus probable reserves in the Princess area of 556 Mbbl of crude oil, 924  Mmcf of natural gas and 12 Mbbl of NGL as of December 31, 2007.

Saskatchewan

In May 2007, Enterra purchased Trigger Resources. Included in the purchase were several pools in west central Saskatchewan, including Primate and Liebenthal.  In addition, there were several minor non-core pools scattered geographically.  McDaniel assigned total proved plus probable reserves of 15.5 Bcf of natural gas and 1,280 Mbbls of heavy oil to the Trigger Resources fields, as of December 31, 2007.

Primate

The Primate pool was the main producing asset of the Trigger Resources purchase and is 100% owned by Enterra. Production is from the McLaren formation and although the oil is a relatively heavy (11° API), its gasified nature allows high initial production rates of up to 250 bbls/day per well of oil under primary recovery.

The pool is covered by 3D seismic and three successful wells were drilled in 2007 to further delineate the pool edges. Plans for 2008 include drilling infill wells and completing a study of secondary recovery opportunities in the pool which potentially could double the ultimate recoverable reserves.

At year end 2007 the Primate area was producing nearly 1,000 bbls/day of crude oil and over 1,500 mcf/day of gas before royalties, and the Trust had over 22,000 net undeveloped acres of land.

Liebenthal

The gas production from the Liebenthal pool comes from the Viking formation. The three highly productive wells in the pool are 100% owned by Enterra. Seismic indicates that the pool is structurally controlled and future opportunities include infill drilling of the main pool and exploiting up-hole potential in the Belly River formation. At year end 2007, Liebenthal production was over 3,100 mcf/day of natural gas on a working interest basis before royalties, with more than 18,000 net undeveloped acres of land.

Powder River Basin, Montana and Wyoming

We have a variety of coal-bed methane assets in the Powder River Basin of Wyoming and southern Montana.  Average production for 2007 was approximately 143 BOE/d from the property near Gillette, Wyoming.  Several developing exploitation and exploration plays are located in various parts of the basin.

We also hold a significant acreage position in the Oyster Ridge area of southwest Wyoming.  Wet coal dewatering projects are currently underway with promising early indications while other areas are in the planning and evaluation stages with the emphasis on longer term potential.

Oklahoma

In Oklahoma, we have approximately 94,300 gross developed and undeveloped acres of land, with an average working interest of 80.4% at year end 2007, centered in Grant, Lincoln and Logan Counties.  We generally have 20-25% working interest in producing wells drilled by our US Farmout Partner, depending on the participation of other parties in the wells.  The key producing horizon is the Hunton formation.  The Hunton formation is a carbonate rock formation which has been largely ignored by the industry in areas with high water/hydrocarbon production ratios.  Over the last decade, new drilling and production techniques have enabled the profitable development of hydrocarbon production from these areas of the Hunton formation.  Extensive dewatering lowers pressure allowing the liberation and mobilization of oil and gas from smaller rock pores.  In our experience, total gross peak hydrocarbon production rates average 150 BOE/d per horizontal well within six months after drilling and tie-in.  The average gross proved plus probable reserves are approximately 280,000 boe per horizontal well.

Our average production for 2007 in Oklahoma was 25.6 Mmcf/d of natural gas and 630 bbl/d of crude oil and NGL.  Haas attributed total proved and probable reserves of 1,432 Mbbl of crude oil and 69.1 Bcf of natural gas to this area as of December 31, 2007, resulting in a RLI of 7.3 years. December 2007 rates were 23.2 Mmcf/d and 383 bbl/d oil.  These rates reflect the effects of the severe ice storm in early December that damaged the electrical infrastructure supplying power to our producing wells and water disposal systems.  Operating costs on our properties averaged $10.45/boe during 2007.  We maintain a fully staffed field office in Carney, Oklahoma about 50 miles northeast of Oklahoma City.  Our staff complement as of December 31, 2007 is 44 people including our Chief Operating Officer, US Operations.

We have approximately 46,100 net undeveloped acres in the Alfalfa, Grant, Lincoln and Logan Counties in Oklahoma. To date, we have identified more than 100 drilling locations on our properties.

Under a farmout agreement, the US Farmout Partner pays 100% of the costs of drilling and completing each well on Trust lands to earn a 70% working interest.  The farmout agreement requires the US Farmout Partner to drill not less than 30 wells during rolling twenty-month periods.  By the end of 2007, 30 producing wells had been drilled and completed, another well had been drilled and was awaiting completion, and three wells were drilling. In addition, two saltwater disposal wells had been drilled.   Enterra pays 100% of the costs of drilling the required water disposal wells and associated infrastructure, but recovers 100% of those costs plus interest over a 3-year period through a capital recovery agreement with the US Farmout Partner.

Environmental Protection

Our operations in Canada and the United States are subject to stringent government laws and regulations regarding pollution, protection of the environment and the handling and transport of hazardous materials.  These laws and regulations may impose administrative, civil and criminal penalties as well as joint and several, strict liability for failure to comply, and generally require us to remove or remedy the effect of our activities on the environment and present and former operating sites, including dismantling production facilities and remediate damage caused by the use or release of specified substances.  The Board reviews our environment policy and our compliance with applicable laws and regulations.  Monitoring and reporting programs for environment, health and safety performance in day-to-day operations, as well as inspections and assessments, are designed to provide assurance that environmental and regulatory standards are met.  Contingency plans are in place for a timely response to an environmental event and remediation/reclamation programs are in place and utilized to restore the environment.

We currently own or lease, and have in the past owned or leased, properties that have been used for oil and natural gas exploration and production activities for many years.  Although we used operating and disposal practices that were standard in the industry at the time, petroleum hydrocarbons or wastes may have been disposed of or released on or under the properties owned or leased by us on or under other locations where such wastes have been taken for disposal.  In addition, some of these properties have been operated by third parties whose treatment and disposal or release of petroleum hydrocarbons and wastes were not under our control, including when these properties were owned or leased by any previous owner(s).  These properties and the materials disposed or released on them may be subject to joint and several, strict liability laws at the federal, state and/or provincial levels.  Under such laws, we could be required to remove or remediate previously disposed wastes or property contamination, or to perform remedial activities to prevent future contamination.  We are currently involved in several remediation projects but we do not believe these costs to be material to our operations or financial position.

We expect to incur abandonment and site reclamation costs as existing oil and gas properties are abandoned and reclaimed.  Between late 2006 and mid-2007, the Trust experienced three pipeline failures in Canada.  As well, we experienced three spills that required clean-up beyond our facility lease in Oklahoma.  While the balance of the environmental reclamation work has been completed, there will be some work including vegetation and subsequent monitoring with the potential for further evaluation required for these areas.  Beyond these specific pipeline repair sites, we do not anticipate making any material expenditure for any reclamation work other than normal compliance with the environmental regulations in 2007.

Abandonment and Reclamation Costs

We estimate well abandonment costs on an area-by-area basis.  Such costs are included in the Reserve Reports as deductions in arriving at future net revenue.  The expected total abandonment costs included in the Reserve Reports under the proved reserves category is $27.0 million undiscounted, $13.6 million discounted at 10% to abandon 599.6 net wells. It is estimated the approximately $3.0 million of this total will be spent over the next 3 years.

Tax Horizon

Canadian

Under the current structure, cash is transferred to the Trust by way of interest and redemptions of securities from the operating subsidiaries to the Trust.  The Trust, in turn, allocates all of its taxable income to the unitholders.  With the exception of capital taxes in certain provinces, no Canadian income taxes are currently expected to be incurred by the Trust or its Canadian operating subsidiaries.

United States

U.S. income related cash taxes have not been paid by the Trust or its U.S. Operating Subsidiaries for the year ended December 31, 2007.  The income from our U.S. operations (reduced by any deductible interest expense on debt held by the Trust or its Canadian Operating Subsidiaries) is subject to United States income tax under U.S. income tax rules and regulations.  As a result, our U.S. operations may incur cash U.S. income taxes in the future.  In addition, as funds are repatriated to Canada, withholding taxes that are required by U.S. tax law may become payable.

Exploration and Development Activities

The following table sets forth the gross and net development wells that we participated in during the year ended December 31, 2007.  We did not participate in any exploration wells during 2007.  In the farm-in arrangement with the US Farmout Partner in Oklahoma, we have had no interest in dry holes and have a carried interest in producing wells.  The carried interest in the producing wells is shown in this table for wells associated with this arrangement.

CAPITAL STRUCTURE

The Trust Indenture

Our principal undertaking is to issue Trust Units and to acquire and hold debt instruments, securities, royalties and other interests.  The Operating Subsidiaries carry on the business of acquiring and holding interests in petroleum and natural gas properties and assets related thereto.  Cash flow from the properties is flowed from the Trust Subsidiaries to the Trust primarily through (i) payments of interest and principal in respect of the Series Notes, (ii) payments of interest and principal in respect of the CT Notes, and (iii) dividends declared on the common shares of certain Operating Subsidiaries and/or redemptions of preferred shares of certain Operating Subsidiaries, which amounts are transferred from EECT to the Trust as payments of interest or principal on the CT Notes.  Cash flow received by the Trust is distributed to our Unitholders on a monthly basis.

Trust Units and Other Securities

Trust Units

An unlimited number of Trust Units may be created and issued pursuant to our Trust Indenture.  See Description of Trust Units.

Series Notes

The Series Notes are unsecured debt obligations of the Operating Subsidiaries and are subordinated to all of our Senior Indebtedness.  They bear interest at various annual rates, expire at various dates up to 2033 and the principal amounts of the notes vary as additional funds are loaned by us to the Operating Subsidiaries or as principal repayments are made on the notes.  Interest for each month is payable monthly in arrears on the 15th day of the month.

CT Notes

The CT Notes are subordinated, demand participating promissory notes.  The CT Notes were issued by EECT to the Trust. Redemptions and returns of capital on shares of EEC held by EECT may be made from time to time and applied as prepayments of the principal amount of the CT Notes.  The CT Notes bear interest at a rate that is reset from time to time to approximate the return on investments held by EECT.

Income Streams

A portion of the cash flows generated by the assets held, directly or indirectly, by the Trust is distributed to our Unitholders.  Our Trustee may, upon the recommendation of the board of EEC in respect of any period, declare payable to our Unitholders all or any part of the net income of the Trust.  The Trusts primary sources of cash flow are payments of interest and repayments of principal from the Trust Subsidiaries in respect of indebtedness of each of those entities to and in favour of the Trust.

Unitholder Limited Liability

Our Trust Indenture provides that no Unitholder, in its capacity as such, shall incur or be subject to any liability in contract or in tort or of any other kind whatsoever, including taxes payable, in connection with the Trust or its obligations or affairs and, in the event that a court determines that Unitholders are subject to any such liabilities, the liabilities will be enforceable only against, and will be satisfied only out of the Trusts assets. Pursuant to our Trust Indenture, the Trust will indemnify and hold harmless each Unitholder from any costs, damages, liabilities, expenses, charges or losses suffered by a Unitholder from or arising as a result of such Unitholder not having such limited liability.

Our Trust Indenture provides that all contracts signed by or on behalf of the Trust must contain a provision to the effect that such obligation will not be binding upon Unitholders personally. Notwithstanding the terms of our Trust Indenture, Unitholders may not be protected from liabilities of the Trust to the same extent a shareholder is protected from the liabilities of a corporation.

The activities of the Trust and the Trust Subsidiaries are conducted in such a way, upon advice of counsel, and in such jurisdictions as to avoid as far as possible any material risk of liability to our Unitholders for claims against the Trust including by obtaining appropriate insurance, where available, for the operations of the Operating Subsidiaries and by having contracts signed by or on behalf of the Trust include a provision that such obligations are not binding upon Unitholders personally.

Issuance of Trust Units

Our Trust Indenture provides that Trust Units, including rights, warrants (including so called special warrants which may be exercisable for no additional consideration) and other securities to purchase, to convert into or to exchange into Trust Units, may be created, issued, sold and delivered on such terms and conditions and at such times as our Trustee may determine, including, without limitation, instalment or subscription receipts.  Our Trust Indenture also provides that our Trustee may authorize the creation and issuance of Debentures, notes and other evidences of indebtedness of the Trust, which Debentures, notes or other evidences of indebtedness may be created and issued from time to time on such terms and conditions to such persons and for such consideration as our Trustee may determine.

Trustee

Olympia Trust Company is the Trustee of the Trust. The Trustee is responsible for, among other things, accepting subscriptions for Trust Units and issuing Trust Units pursuant thereto, maintaining the books and records of the Trust and providing timely reports to our Unitholders. The Trust Indenture provides that the Trustee shall exercise its powers and carry out its functions thereunder as trustee honestly, in good faith and in the best interests of the Trust and the Unitholders and, in connection therewith, shall exercise that degree of care, diligence and skill that a reasonably prudent trustee would exercise in comparable circumstances.

The initial term of the Trustees appointment was until the third annual meeting of Unitholders in May, 2006.  At the June 2007 annual meeting the Unitholders re-appointed Olympia Trust Company as Trustee for an additional three year term, and thereafter, the Unitholders shall reappoint or appoint a successor to the Trustee at the annual meeting of Unitholders three years following the reappointment or appointment of the successor to the Trustee. The Trustee may also be removed by special resolution of Unitholders.  Such resignation or removal becomes effective upon the acceptance or appointment of a successor trustee.

Liability of the Trustee

The Trustee, its directors, officers, employees, shareholders and agents are not liable to any Unitholder or any other person, in tort, contract or otherwise, in connection with any matter pertaining to the Trust or the property of the Trust, arising from the exercise by the Trustee of any powers, authorities or discretion conferred under the Trust Indenture, including, without limitation, any action taken or not taken in good faith in reliance on any documents that are, prima facie, properly executed, any depreciation of, or loss to, the property of the Trust incurred by reason of the sale of any asset, any inaccuracy in any evaluation provided by any other appropriately qualified person, any reliance on any such evaluation, any action or failure to act of EEC, or any other person to whom the Trustee has, with the consent of EEC, delegated any of its duties hereunder, or any other action or failure to act (including failure to compel in any way any former trustee to redress any breach of trust or any failure by EEC to perform its duties under or delegated to it under the Trust Indenture or any other contract), unless such liabilities arise out of the gross negligence, wilful default or fraud of the Trustee or any of its directors, officers, employees or shareholders. If the Trustee has retained an appropriate expert, adviser or legal counsel with respect to any matter connected with its duties under the Trust Indenture, the Trustee may act or refuse to act based on the advice of such expert, adviser or legal counsel, and the Trustee shall not be liable for and shall be fully protected from any loss or liability occasioned by any action or refusal to act based on the advice of any such expert, adviser or legal counsel. In the exercise of the powers, authorities or discretion conferred upon the Trustee under the Trust Indenture, the Trustee is and shall be conclusively deemed to be acting as Trustee of the assets of the Trust and shall not be subject to any personal liability for any debts, liabilities, obligations, claims, demands, judgments, costs, charges or expenses against or with respect to the Trust or the property of the Trust. In addition, the Trust Indenture contains other customary provisions limiting the liability of the Trustee.

Special Voting Rights

The Trust Indenture allows for the creation and issuance of an unlimited number of Special Voting Rights which enable the Trust to provide voting rights to holders of securities issued by certain Trust Subsidiaries (such as exchangeable shares) that may be issued by subsidiaries of the Trust in connection with exchangeable share transactions.

Holders of Special Voting Rights are not entitled to any distributions of any nature whatsoever from the Trust.  Each holder is entitled to attend and vote at meetings of Unitholders according to the terms of the instrument pursuant to which the Special Voting Rights are issued.  Each holder of outstanding Special Voting Rights is entitled to that number of votes equal to the number of votes attached to the Trust Units for which the securities relating to such Special Voting Rights held by such holder are exchangeable, exercisable or convertible.  Holders of Special Voting Rights are also entitled to receive all notices, communications or other documentation required to be given or otherwise sent to Unitholders. Except for the right to attend and vote at meetings of Unitholders and receive notices, communications and other documentation sent to Unitholders, the Special Voting Rights do not confer upon the holders thereof any other rights.

Redemption Right

Our Trust Units are redeemable at any time on demand by the holders thereof upon delivery to the transfer agent of the Trust of the certificate or certificates representing such Trust Units and a duly completed and properly executed notice requiring redemption. Upon receipt of the notice to redeem Trust Units by our transfer agent, the holder thereof will only be entitled to receive a price per Trust Unit (the Market Redemption Price) equal to the lesser of: (iii) 90% of the market price of the Trust Units on the principal market on which the Trust Units are quoted for trading during the 10 trading day period commencing immediately after the date on which the Trust Units are tendered to the Trust for redemption; and (iv) the closing market price on the principal market on which the Trust Units are quoted for trading on the date that the Trust Units are so tendered for redemption. Where more than one market exists for the Trust Units, the principal market shall mean the market on which the Trust Units experience the greatest volume of trading activity on the date or for the period in question, as applicable.

For the purposes of this calculation, market price is an amount equal to the simple average of the closing price of the Trust Units for each of the trading days on which there was a closing price; provided that, if the applicable exchange or market does not provide a closing price but only provides the highest and lowest prices of the Trust Units traded on a particular day, the market price shall be an amount equal to the simple average of the average of the highest and lowest prices for each of the trading days on which there was a trade; and provided further that if there was trading on the applicable exchange or market for fewer than five of the 10 trading days, the market price shall be the simple average of the following prices established for each of the 10 trading days: the average of the last bid and last ask prices for each day on which there was no trading; the closing price of the Trust Units for each day that there was trading if the exchange or market provides a closing price; and the average of the highest and lowest prices of the Trust Units for each day that there was trading, if the market provides only the highest and lowest prices of Trust Units traded on a particular day. The closing market price is: an amount equal to the closing price of the Trust Units if there was a trade on the date; an amount equal to the average of the highest and lowest prices of the Trust Units if there was trading and the exchange or other market provides only the highest and lowest prices of Trust Units traded on a particular day; and the average of the last bid and last ask prices if there was no trading on the date.

We will pay the aggregate Market Redemption Price in respect of any Trust Units surrendered for redemption during any calendar month by cheque on the last day of the following month. The entitlement of Unitholders to receive cash upon the redemption of their Trust Units is subject to the limitation that the total amount payable by the Trust in respect of such Trust Units and all other Trust Units tendered for redemption in the same calendar month and in any preceding calendar month during the same year shall not exceed $100,000; provided that we may, in our sole discretion, waive such limitation in respect of any calendar month. If this limitation is not so waived, the Market Redemption Price payable by the Trust in respect of Trust Units tendered for redemption in such calendar month will be paid on the last day of the following month as follows: (i) secondly, to the extent that the Trust does not hold Series Notes having a sufficient principal amount outstanding to effect such payment, by the Trust issuing its own promissory notes to Unitholders who exercised the right of redemption having an aggregate principal amount equal to any such shortfall (herein referred to as Redemption Notes).

Notwithstanding the foregoing, the distribution of any Series Notes and the issuance of any Redemption Notes will be conditional upon the receipt of all necessary regulatory approvals and the making of all necessary governmental registrations, declarations and filings, including, without limitation, any required registration of the Series Notes or Redemption Notes, as applicable, to be distributed or issued in respect of the payment of the Market Redemption Price, and any required qualification of our Trust Indenture relating to such Series Notes or Redemption Notes, as the case may be, under the securities laws of the United States.

If at the time Trust Units are tendered for redemption by a Unitholder, (i) trading of our outstanding Trust Units is suspended or halted on any stock exchange on which our Trust Units are listed for trading or, if not so listed, on any market on which the Trust Units are quoted for trading, on the date such Trust Units are tendered for redemption or for more than five trading days during the 10 trading day period, commencing immediately after the date such Trust Units were tendered for redemption then such Unitholder shall, instead of the Market Redemption Price, be entitled to receive a price per Trust Unit (the Appraised Redemption Price) equal to 90% of the fair market value thereof as determined by EEC as at the date on which such Trust Units were tendered for redemption. The aggregate Appraised Redemption Price payable by the Trust in respect of Trust Units tendered for redemption in any calendar month will be paid on the last day of the third following month by, at the option of the Trust: (i) a distribution of Series Notes and/or Redemption Notes as described above.

It is anticipated that this redemption right will not be the primary mechanism for holders of our Trust Units to dispose of their Trust Units. Series Notes or Redemption Notes, which may be distributed in specie to Unitholders in connection with a redemption, will not be listed on any stock exchange and no market is expected to develop in such Series Notes or Redemption Notes. Series Notes or Redemption Notes may not be qualified investments for trusts governed by registered retirement savings plans, registered retirement income funds, deferred profit sharing plans and registered education savings plans.

Meetings of Unitholders

Our Trust Indenture provides that meetings of our Unitholders must be called and held for, among other matters, the election or removal of our Trustee, the appointment or removal of our auditors, the approval of amendments to our Trust Indenture (except as described under Amendments to the Trust Indenture), the sale of the property of the Trust as an entirety or substantially as an entirety, and the commencement of winding up the affairs of the Trust.

---





A meeting of our Unitholders may be convened at any time and for any purpose by our Trustee and must be convened, except in certain circumstances, if requisitioned in writing by: (i) the holders of Trust Units and Special Voting Rights holding in aggregate not less than 5% of the votes entitled to be voted at a meeting of our Unitholders. A requisition must, among other things, state in reasonable detail the business purpose for which the meeting is to be called.

Unitholders and holders of Special Voting Rights may attend and vote at all meetings of Unitholders either in person or by proxy and a proxy holder need not be a Unitholder. Two persons present in person or represented by proxy and representing in the aggregate at least 5% of the votes attaching to all outstanding Trust Units shall constitute a quorum for the transaction of business at all such meetings. For purposes of determining such quorum, the holders of any issued Special Voting Rights who are present at the meeting shall be regarded as representing outstanding Trust Units equivalent in number to the votes attaching to such Special Voting Rights.

Our Trust Indenture contains provisions as to the notice required and other procedures with respect to the calling and holding of meetings of our Unitholders in accordance with the requirements of applicable laws.

Exercise of Voting Rights

Our Trustee is prohibited from authorizing or approving:

•

any sale, lease or other disposition of, or any interest in, all or substantially all of the assets owned, directly or indirectly, by the Trust, except in conjunction with an internal reorganization of the direct or indirect assets of the Trust, as a result of which the Trust has substantially the same interest, whether direct or indirect, in the assets as the interest, whether direct or indirect, that it had prior to the reorganization;

•

any merger, amalgamation, arrangement, reorganization, recapitalization, business combination or similar transaction as the case may be, of the Trust with any other person, except: (i) in conjunction with an internal reorganization as referred to in the bulleted paragraph above, or (ii) where immediately following completion of such transaction, the holders (or affiliates thereof) of equity interests in such other person (such holder being determined immediately prior to the entering into of such transaction) do not hold, directly or indirectly (on a fully diluted basis), more than 50% of, as applicable, (x) the issued and outstanding voting rights attributable to securities of the issuer which results from such transaction, or (y) the issued and outstanding Trust Units; or

•

the winding up, liquidation or dissolution of the Trust prior to the end of the term of the Trust except in conjunction with an internal reorganization as referred toin the first bulleted paragraph above;

without the prior approval of our Unitholders by Special Resolution at a meeting of Unitholders called for that purpose.

In addition, our Trustee is prohibited from authorizing EECT to vote any shares of EEC in respect of:

•

any sale, lease or other disposition of, or any interest in, all or substantially all of the assets owned, directly or indirectly, by EEC, the Trust or EPP, except in conjunction with an internal reorganization of the direct or indirect assets of EEC, EECT or EPP, as the case may be, as a result of which EECT has substantially the same interest, whether direct or indirect, in the assets as the interest, whether direct or indirect, that it had prior to the reorganization;

•

any merger, amalgamation, arrangement, reorganization, recapitalization, business combination or similar transaction as the case may be, of the Trust with any other person, except: (i) in conjunction with any internal reorganization as referred to in the bulleted paragraph above, or (ii) where immediately following completion of such transaction, the holders (or affiliates thereof) of equity interests in such other person (such holders being determined immediately prior to the entering into of such transaction) do not hold, directly or indirectly (on a fully diluted basis), more than 50% of, as applicable, (x) the issued and outstanding voting rights attributable to securities of the issuer which results from such transaction, or (y) the issued and outstanding Trust Units;

•

any amendment to the articles of EEC to increase or decrease the minimum or maximum number of directors;

•

any material amendments to the articles of EEC to change the authorized share capital or amend the rights, privileges, restrictions and conditions attaching to any class of EECs shares in a manner which may be prejudicial to EECT; or

•

any material amendment to the EECT indenture or the EPP partnership agreement which may be prejudicial to EECT;

without the prior approval of our Unitholders by Special Resolution at a meeting of Unitholders called for that purpose.

Finally, our Trustee is prohibited from authorizing EECT to vote any shares of EEC with respect to any matter which under applicable law (including policies of Canadian securities commissions) or applicable stock exchange rules would require the approval of the holders of shares of EEC by ordinary resolution or special resolution, without the prior approval of our Unitholders by ordinary resolution or special resolution, as the case may be.

Amendments to the Trust Indenture

Our Trust Indenture may be amended or altered from time to time by Special Resolution of our Unitholders.  On May 18, 2006, the Unitholders by Special Resolution, approved an amendment to our Trust Indenture which somewhat broadens the ability of the Trust to undertake certain types of corporate transactions without the necessity of obtaining Unitholder approval, unless otherwise required by applicable law.  Our Trustee may, without the approval of our Unitholders, amend our Trust Indenture for the purpose of:

•

ensuring the Trusts continuing compliance with applicable laws or requirements of any governmental agency or authority;

•

ensuring that the Trust will satisfy the provisions of each of subsections 108(2) and 132(6) and paragraph 132(7)(a) of the Tax Act as from time to time amended or replaced;

•

providing for and ensuring (i) the filing of income tax returns necessary or desirable for the purposes of United States federal income tax; or (ii)compliance by the Trust with any other applicable provisions of United States federal income tax law;

•

changing the situs of or the laws governing the Trust, which, in the opinion of our Trustee, is desirable in order to provide Unitholders with the benefit of any legislation limiting their liability; and

•

ensuring that additional protection is provided for the interests of Unitholders as our Trustee may consider expedient.

Takeover Bid

Our Trust Indenture contains provisions to the effect that if a takeover bid is made for our Trust Units and not less than 90% of the Trust Units (other than Trust Units held at the date of the takeover bid by or on behalf of the offeror or associates or affiliates of the offeror) are taken up and paid for by the offeror, the offeror will be entitled to acquire the Trust Units held by Unitholders who did not accept the take-over bid on the terms offered by the offeror.  In the event of a take-over bid for our Trust Units, any holder of a security exchangeable directly or indirectly into Trust Units may, unless prohibited by the terms and conditions of such exchangeable security, convert, exercise or exchange such exchangeable security for the purpose of tendering Trust Units to the take-over bid, unless an identical offer is made by the offeror to purchase such exchangeable security.

Termination of the Trust

Unitholders may vote to terminate the Trust at any meeting of Unitholders duly called for that purpose, subject to the following: (i) a meeting may only be held for the purpose of such a vote if requested in writing by the holders of not less than 20% of our outstanding Trust Units and Special Voting Rights; (ii) a quorum of the holders of 50% of the issued and outstanding Trust Units and Special Voting Rights must be present in person or by proxy; and (iii) the termination must be approved by Special Resolution of our Unitholders.

Unless the Trust is earlier terminated or extended by vote of our Unitholders, the Trust will continue in full force and effect for a period which shall end twenty-one years after the date of death of the last surviving issue of Her Majesty, Queen Elizabeth II. In the event that the Trust is wound up, our Trustee will sell and convert into money the property of the Trust in one transaction or in a series of transactions at public or private sale and do all other acts appropriate to liquidate the property of the Trust in accordance with any applicable laws or requirements of any governmental agency or authority, and shall in all respects act in accordance with the directions, if any, of our Unitholders in respect of the termination authorized pursuant to the Special Resolution of Unitholders authorizing the termination of the Trust. After paying, retiring or discharging or making provision for the payment, retirement or discharge of all known liabilities and obligations of the Trust and providing for indemnity against any other outstanding liabilities and obligations, our Trustee shall distribute the remaining proceeds of the sale of the assets together with any cash forming part of the property of the Trust among our Unitholders in accordance with their pro rata interests.

Reporting to Unitholders

An independent recognized firm of chartered accountants audits the financial statements of the Trust annually.  The audited consolidated financial statements of the Trust, together with the report of such chartered accountants, will be mailed by our Trustee to Unitholders and the unaudited interim financial statements of the Trust will be mailed to Unitholders within the periods prescribed by securities legislation. The year-end of the Trust is December 31.  The Trust is subject to the continuous disclosure obligations under all applicable securities legislation.

Description of Debentures

General

Our Debentures were issued under a debenture trust indenture (the Debenture Indenture) dated as of November 21, 2006 and April 26, 2007 among the Trust, EEC and Olympia Trust Company (the Debenture Trustee). An unlimited number of Debentures are authorized for issue.

Our Debentures are dated as of November 21, 2006 and April 26, 2007 respectively.  They were issuable only in denominations of $1,000 and integral multiples thereof. The maturity date for the Debentures is December 31, 2011 and June 30, 2012 respectively.

Our Debentures bear interest from the date of issue at 8.0% and 8.25% per annum, which is payable semi-annually in arrears on June 30 and December 31 in each year, commencing June 30, 2007 and December 31, 2007 respectively.

The principal amount of our Debentures is payable in lawful money of Canada or, at our option and subject to applicable regulatory approval, by payment of our Trust Units as further described under Payment upon Redemption or Maturity and Redemption and Purchase. The interest on our Debentures is payable in lawful money of Canada including, at our option and subject to applicable regulatory approval, in accordance with the Unit Interest Payment Election as described under Interest Payment Option.

Our Debentures are direct obligations of the Trust and are not secured by any mortgage, pledge, hypothec or other charge and are subordinated to other liabilities of the Trust as described under Subordination.  Other than as described herein, the Debenture Indenture do not restrict us from incurring additional indebtedness or liabilities or from mortgaging, pledging or charging our properties to secure any indebtedness.

Conversion Privilege

Our Debentures are convertible at the holders option into fully paid and non-assessable Trust Units at any time prior to the close of business on the earlier of the maturity date and the business day immediately preceding the date specified by us for redemption of our Debentures, at a conversion price of $9.25 and $6.80 per Trust Unit respectively, being a conversion rate of 108.1081 and 147.0588 Trust Units for each $1,000 principal amount of Debentures respectively. Holders converting their Debentures will receive all accrued and unpaid interest thereon in cash to the date of conversion.

Subject to the provisions thereof, the Debenture Indenture provides for the adjustment of the conversion price in certain events including: (a) the subdivision or consolidation of our outstanding Trust Units; (b) the distribution of our Trust Units to holders of Trust Units by way of distribution or otherwise other than an issue of securities to holders of our Trust Units who have elected to receive distributions in securities of the Trust in lieu of receiving cash distributions paid in the ordinary course; (c) the issuance of options, rights or warrants to all or substantially all of the holders of our Trust Units entitling them to acquire our Trust Units or other securities convertible into our Trust Units at less than 95% of the then current market price (as defined below) of our Trust Units; and (d) the distribution to all or substantially of the holders of our Trust Units of any securities or assets (other than cash distributions and equivalent distributions in securities paid in lieu of cash distributions in the ordinary course). There will be no adjustment of the conversion price in respect of any event described in (b), (c) or (d) above if the holders of our Debentures are allowed to participate as though they had converted their Debentures prior to the applicable record date or effective date.



- 63 -



---





We are not required to make adjustments in the conversion price unless the cumulative effect of such adjustments would change the conversion price by at least 1%.

The term current market price is defined in the Debenture Indenture to mean the weighted average trading price of our Trust Units on the Toronto Stock Exchange for the 20 consecutive trading days ending on the fifth trading day preceding the date of the applicable event.

In the case of any reclassification or capital reorganization (other than a change resulting from consolidation or subdivision) of our Trust Units or in the case of any consolidation, amalgamation or merger of the Trust with or into any other entity, or in the case of any sale or conveyance of the properties and assets of the Trust as, or substantially as, an entirety to any other entity, or a liquidation, dissolution or winding-up of the Trust, the terms of the conversion privilege shall be adjusted so that each holder of a Debenture shall, after such reclassification, capital reorganization, consolidation, amalgamation, merger, sale, conveyance, liquidation, dissolution or winding-up, be entitled to receive the number of Trust Units such holder would be entitled to receive if on the effective date thereof, it had been the holder of the number of Trust Units into which the Debenture was convertible prior to the effective date of such reclassification, capital reorganization, consolidation, amalgamation, merger, sale, conveyance, liquidation, dissolution or winding-up.

No fractional Trust Units will be issued on any conversion but in lieu thereof we shall satisfy fractional interests by a cash payment equal to the current market price of any fractional interest.

Redemption and Purchase

Our Debentures are not redeemable on or before December 31, 2009 and June 30, 2010 respectively. On or after January 1, 2010 and July 1, 2010 respectively and prior to maturity, our Debentures may be redeemed in whole or in part from time to time at our option on not more than 60 days and not less than 30 days notice, at a Redemption Price of $1,050 per debenture after December 31, 2009 and June 30, 2010 respectively, on or before December 31, 2010 and June 30, 2011 respectively, at a Redemption Price of $1,050 per debenture and on or after January 1, 2011 and July 1, 2011 respectively and prior to maturity at a Redemption Price of $1,025 per debenture, in each case, plus accrued and unpaid interest thereon, if any.

In the case of redemption of less than all of our Debentures, the Debentures to be redeemed will be selected by the Debenture Trustee on a pro rata basis or in such other manner as the Debenture Trustee deems equitable.

We have the right to purchase our Debentures in the market, by tender or by private contract.

Payment upon Redemption or Maturity

On redemption or at maturity, we will, subject to our option to make such repayment in Trust Units as described below, repay the indebtedness represented by our Debentures by paying to the Debenture Trustee in lawful money of Canada an amount equal to the aggregate Redemption Price of the outstanding Debentures which are to be redeemed or the principal amount of the outstanding Debentures which have matured, together with accrued and unpaid interest thereon. We may, at our option, on not more than 60 and not less than 40 days prior notice and subject to applicable regulatory approval, elect to satisfy our obligation to pay the applicable Redemption Price of the Debentures which are to be redeemed or the principal amount of the Debentures which have matured, as the case may be, by issuing freely tradeable Trust Units to the holders of the Debentures. Any accrued and unpaid interest thereon will be paid in cash. The number of Trust Units to be issued will be determined by dividing the aggregate Redemption Price of the outstanding Debentures which are to be redeemed or the principal amount of the outstanding Debentures which have matured, as the case may be, by 95% of the weighted average trading price of our Trust Units for the 20 consecutive trading days ending on the fifth trading day preceding the date fixed for redemption or the maturity date, as the case may be. No fractional Trust Units will be issued on redemption or maturity but in lieu thereof we shall satisfy fractional interests by a cash payment equal to the current market price of any fractional interest.



- 64 -



---







Subordination

The payment of the principal and premium, if any, of, and interest on, our Debentures is subordinated in right of payment, as set forth in the Debenture Indenture, to the prior payment in full of all of our Senior Indebtedness and indebtedness to our trade creditors. Senior Indebtedness is defined in the Debenture Indenture as the principal of and premium, if any, and interest on and other amounts in respect of all of our indebtedness (whether outstanding as at the date of the Debenture Indenture or thereafter incurred), other than indebtedness evidenced by our Debentures and all other existing and future debentures or other instruments of the Trust which, by the terms of the instrument creating or evidencing the indebtedness, is expressed to be pari passu with, or subordinate in right of payment to, our Debentures.  Subject to statutory or preferred exceptions or as may be specified by the terms of any particular securities, each Debenture issued under the Debenture Indenture ranks pari passu with each other Debenture, and with all of our other present and future subordinated and unsecured indebtedness except for sinking provisions (if any) applicable to different series of Debentures or similar types of obligations.

The Debenture Indenture provides that in the event of any insolvency or bankruptcy proceedings, or any receivership, liquidation, reorganization or other similar proceedings relative to us, or to our property or assets, or in the event of any proceedings for our voluntary liquidation, dissolution or other winding-up, whether or not involving insolvency or bankruptcy, or any marshalling of our assets and liabilities, then those holders of Senior Indebtedness, including to our trade creditors, will receive payment in full before the holders of our Debentures will be entitled to receive any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in any such event in respect of any of our Debentures or any unpaid interest accrued thereon. The Debenture Indenture also provides that we cannot make any payment, and the holders of our Debentures are not entitled to demand, institute proceedings for the collection of, or receive any payment or benefit (including without any limitation by set-off, combination of accounts or realization of security or otherwise in any manner whatsoever) on account of indebtedness represented by our Debentures (a) in a manner inconsistent with the terms (as they exist on the date of issue) of our Debentures or (b) at any time when an event of default has occurred under the Senior Indebtedness and is continuing and the notice of such event of default has been given by or on behalf of the holders of Senior Indebtedness to us, unless the Senior Indebtedness has been repaid in full.

Our Debentures are also effectively subordinate to claims of creditors of the Trust Subsidiaries except to the extent we are a creditor of such subsidiaries ranking at least pari passu with such other creditors. Specifically, our Debentures will be effectively subordinated in right of payment to the prior payment in full of all indebtedness under our Revolving and Operating Credit Facilities.

Priority over Trust Distributions

Our Trust Indenture provides that certain expenses of the Trust must be deducted in calculating the amount to be distributed to our Unitholders. Accordingly, the funds required to satisfy the interest payable on our Debentures, as well as the amount payable upon redemption or maturity of our Debentures or upon an Event of Default (as defined below), will be deducted and withheld from the amounts that would otherwise be payable as distributions to our Unitholders.

Change of Control of the Trust

Within 30 days following the occurrence of a change of control of the Trust involving the acquisition of voting control or direction over 66 2/3% or more of our Trust Units (a Change of Control), we are required to make an offer in writing to purchase all of our Debentures then outstanding (the Offer), at a price equal to 101% of the principal amount thereof plus accrued and unpaid interest (the Offer Price).



- 65 -



---





The Debenture Indenture contains notification and repurchase provisions requiring us to give written notice to the Debenture Trustee of the occurrence of a Change of Control within 30 days of such event together with the Offer. The Debenture Trustee will thereafter promptly mail to each holder of Debentures a notice of the Change of Control together with a copy of the Offer to repurchase all the outstanding Debentures.

If 90% or more in aggregate principal amount of our Debentures outstanding on the date of the giving of notice of the Change of Control have been tendered to us pursuant to the Offer, we will have the right and obligation to redeem all the remaining Debentures at the Offer Price. Notice of such redemption must be given by us to the Debenture Trustee within 10 days following the expiry of the Offer, and as soon as possible thereafter, by the Debenture Trustee to the holders of our Debentures not tendered pursuant to the Offer.

Interest Payment Option

We may elect, from time to time, to satisfy our obligation to pay interest on our Debentures (the Interest Obligation), on the date it is payable under the Debenture Indenture (an Interest Payment Date), by delivering sufficient Trust Units to the Debenture Trustee to satisfy all or any part of the Interest Obligation in accordance with the Debenture Indenture (the Unit Interest Payment Election).  The Indenture provides that, upon such election, the Debenture Trustee shall (a) accept delivery from us of our Trust Units, (b) accept bids with respect to, and consummate sales of, such Trust Units, each as we shall direct in our absolute discretion, (c) invest the proceeds of such sales in short-term permitted government securities (as will be defined in the Debenture Indenture) which mature prior to the applicable Interest Payment Date, and use the proceeds received from such permitted government securities, together with any proceeds from the sale of Trust Units not invested as aforesaid, to satisfy the Interest Obligation, and (d) perform any other action necessarily incidental thereto.

The Debenture Indenture sets forth the procedures to be followed by us and the Debenture Trustee in order to effect the Unit Interest Payment Election. If a Unit Interest Payment Election is made, the sole right of a holder of our Debentures in respect of interest is to receive cash from the Debenture Trustee out of the proceeds of the sale of Trust Units (plus any amount received by the Debenture Trustee from us attributable to any fractional Trust Units) in full satisfaction of the Interest Obligation, and the holder of such Debentures has no further recourse to us in respect of the Interest Obligation.

Neither our making of the Unit Interest Payment Election nor the consummation of sales of Trust Units will (a) result in the holders of our Debentures not being entitled to receive on the applicable Interest Payment Date cash in an aggregate amount equal to the interest payable on such Interest Payment Date, or (b) entitle such holders to receive any of our Trust Units in satisfaction of the Interest Obligation.

Events of Default

The Debenture Indenture provides that an event of default (Event of Default) in respect of our Debentures will occur if any one or more of the following described events has occurred and is continuing with respect to our Debentures: (a) failure for 10 days to pay interest on our Debentures when due; (b) failure to pay principal or premium, if any, when due on our Debentures, whether at maturity, upon redemption, by declaration or otherwise; (c) certain events of our bankruptcy, insolvency or reorganization under bankruptcy or insolvency laws; or (d) default in the observance or performance of any material covenant or condition of the Debenture Indenture and continuance of such default for a period of 30 days after notice in writing has been given by the Debenture Trustee to us specifying such default and requiring us to rectify the same. If an Event of Default has occurred and is continuing, the Debenture Trustee may, in its discretion, and shall upon request of holders of not less than 25% in principal amount of the outstanding Debentures, declare the principal of and interest on all outstanding Debentures to be immediately due and payable. In certain cases, the holders of a majority of the principal amount of the Debentures then outstanding may, on behalf of the holders of all Debentures, waive any Event of Default and/or cancel any such declaration upon such terms and conditions as such holders shall prescribe.

Offers for Debentures

The Debenture Indenture contains provisions to the effect that if an offer is made for our Debentures which is a take-over bid for our Debentures within the meaning of theSecurities Act(Alberta) and not less than 90% of our Debentures (other than Debentures held at the date of the take-over bid by or on behalf of the offeror or associates or affiliates of the offeror) are taken up and paid for by the offeror, the offeror will be entitled to acquire our Debentures held by the holders of Debentures who did not accept the offer on the terms offered by the offeror.

Modification

The rights of the holders of our Debentures as well as any other series of Debentures that may be issued under the Debenture Indenture may be modified in accordance with the terms of the Debenture Indenture. For that purpose, among others, the Debenture Indenture contains certain provisions which make binding on all Debenture holders resolutions passed at meetings of the holders of Debentures by votes cast thereat by holders of not less than 66 2/3% of the principal amount of the outstanding Debentures present at the meeting or represented by proxy, or rendered by instruments in writing signed by the holders of not less than 66 2/3% of the principal amount of the outstanding Debentures.  In certain cases, the modification will, instead or in addition, require assent by the holders of the required percentage of Debentures of each particularly affected series.

Limitation on Issuance of Additional Debentures

The Debenture Indenture provides that we shall not issue additional convertible Debentures of equal ranking if the principal amount of all of our issued and outstanding convertible Debentures exceeds 25% of the Total Market Capitalization of the Trust immediately after the issuance of such additional convertible Debentures. Total Market Capitalization is defined in the Debenture Indenture as the total principal amount of all of our issued and outstanding Debentures which are convertible at the option of the holder into our Trust Units plus the amount obtained by multiplying the number of issued and outstanding Trust Units by the current market price of our Trust Units on the relevant date.

Book-Entry System for Debentures

Our Debentures have been issued in book-entry only form and must be purchased or transferred through a participant (a Participant) in the depository service of The Canadian Depository of Securities Limited (CDS).  The Debentures are evidenced by a single book-entry only certificate. Registration of interests in and transfers of our Debentures are made only through the depository service of CDS.

Except as described below, a purchaser acquiring a beneficial interest in our Debentures (a Beneficial Owner) will not be entitled to a certificate or other instrument from the Debenture Trustee or CDS evidencing that purchasers interest therein, and such purchaser will not be shown on the records maintained by CDS, except through a Participant.

We assume no liability for: (a) any aspect of the records relating to the beneficial ownership of our Debentures held by CDS or the payments relating thereto; (b) maintaining, supervising or reviewing any records relating to our Debentures; or (c) any advice or representation made by or with respect to CDS and relating to the rules governing CDS or any action to be taken by CDS or at the direction of its Participants. The rules governing CDS provide that it acts as the agent and depositary for the Participants. As a result, Participants must look solely to CDS and Beneficial Owners must look solely to Participants for the payment of the principal and interest on our Debentures paid by us or on our behalf to CDS.

---





Our Debentures are issued to Beneficial Owners in fully registered and certificate form (the Debenture Certificates) only if: (a) we are required to do so by applicable law; (b) the book-entry only system ceases to exist; (c) we or CDS advises the Debenture Trustee that CDS is no longer willing or able to properly discharge its responsibilities as depositary with respect to our Debentures and we are unable to locate a qualified successor; (d) we, at our option, decide to terminate the book-entry only system through CDS; or (e) after the occurrence of an Event of Default, Participants acting on behalf of Beneficial Owners representing, in the aggregate, more than 25% of the aggregate principal amount of the Debentures then outstanding advise CDS in writing that the continuation of a book-entry only system through CDS is no longer in their best interest provided the Debenture Trustee has not waived the Event of Default in accordance with the terms of the Debenture Indenture.

Upon the occurrence of any of the events described in the immediately preceding paragraph, the Debenture Trustee will be required to notify CDS, for and on behalf of Participants and Beneficial Owners, of the availability through CDS of Debenture Certificates. Upon surrender by CDS of the single certificate representing our Debentures and receipt of instructions from CDS for the new registrations, the Debenture Trustee will deliver our Debentures in the form of Debenture Certificates and thereafter we will recognize the holders of such Debenture Certificates as Debenture holders under the Debenture Indenture.

Interest on our Debentures will be paid directly to CDS while the book-entry only system is in effect. If Debenture Certificates are issued, interest will be paid by cheque drawn on the Trust and sent by prepaid mail to the registered holder or by such other means as may become customary for the payment of interest. Payment of principal, including payment in the form of our Trust Units if applicable, and the interest due, at maturity or on a redemption date, will be paid directly to CDS while the book-entry only system is in effect. If Debenture Certificates are issued, payment of principal, including payment in the form of our Trust Units if applicable, and interest due, at maturity or on a redemption date, will be paid upon surrender thereof at any office of the Debenture Trustee or as otherwise specified in the Debenture Indenture.

Relationship with JED Oil Inc. and JMG Exploration, Inc.

Under an Agreement of Business Principles first dated September 1, 2003, and amendments thereto, properties acquired by the Trust were contract operated and drilled by JMG, a publicly traded oil and gas

exploration company, if they were exploration properties, and contracted, operated and drilled by JED, a publicly traded oil and gas development company, if they were development projects.  Exploration of the properties was done by JMG, which paid 100% of the exploration costs to earn a 70% working interest in the properties. If JMG discovered commercially viable reserves on the exploration properties, the Trust had the right to purchase 80% of JMGs working interest in the properties at a fair value as determined by independent engineers.  Had the Trust elected to develop the properties, development would have been done by JED, which would pay 100% of the development costs to earn 70% of the interests of both JMG and the Trust.  The Trust had a first right to purchase any assets developed by JED.  The Trust does not own any shares in either JMG or JED.  On September 28, 2006, the Trust terminated the Agreement of Business Principles and amendments thereto, and other related agreements with JED.  Concurrent with the termination of the agreements, the Trust settled all amounts owing to JED.

Effective January 1, 2004, the Trust and JED entered into the Technical Services Agreement, which provided for services required to manage the Trusts field operations and governed the allocation of general and administrative expenses between the two entities. Under the Technical Services Agreement, the Trust and JED allocated costs of management, development, exploitation, operations and general and administrative activities on the basis of production and capital expenditures, or as otherwise agreed to between the Trust and JED.  On January 1, 2006, the Trust terminated the Technical Services Agreement with JED.  The Trust now manages its own management, development, exploitation, operations and general and administrative activities.

During the term of the Trusts agreements with JED and JMG, the Chairman of the Trust until March 31, 2006, Reginald (Reg) J. Greenslade, was also the Chairman and Chief Executive Officer of JED and the Chairman of JMG, as well as an owner of securities in all three entities.  Mr. Greenslade also served as President and CEO of the Trust from January 15, 2005 to June 1, 2005.  In addition, H.S. (Scobey) Hartley, a director of Enterra until May 18, 2006, was the President and CEO and a director of JMG and an owner of securities in both entities.

Relationship with Petroflow Energy Ltd.

Petroflow is one of the Trusts strategic partners and has farmed into the Trusts properties in Oklahoma.  Mr. Conrad, the former President and Chief Executive Officer of EEC, as a founder of Petroflow, through his wholly-owned oil and gas company, Macon Resources Ltd., is considered a promoter of Petroflow.  During October 2005 the President of Petroflow contacted Mr. Conrad, who at the time was also the Chairman of Petroflow, concerning a possible acquisition of Oklahoma properties.  Mr. Conrad reviewed the acquisition in his capacities as Chairman of Petroflow and the President and Chief Executive Officer of EEC and determined that the acquisition had merit and that a partnership between the Trust and Petroflow would be advantageous for both parties.  On November 9, 2005, the acquisition and the farmout to Petroflow were brought to the board of EEC for consideration and again on December 6, 2005 for approval.  On each occasion, Mr. Conrad abstained from voting on the matter.  On March 20, 2006, Mr. Conrad resigned as Chairman and as a director of Petroflow.  Mr. Conrad, through Macon Resources Ltd., remains a significant shareholder of Petroflow owning directly or indirectly 16% of the outstanding common shares.  The board of directors of EEC believes that any of the activities undertaken by Mr. Conrad did not interfere, in any material way, with his ability to act with a view to the best interest of either EEC or the Trust.  Mr. Conrad resigned as Chief Executive Officer and director of EEC on November 27, 2007 and February 20, 2008 respectively.



- 76 -



---







A current director, Mr. Roger Giovanetto, on EECs board has reported that he owns directly or indirectly approximately 2% of the outstanding common shares of Petroflow.

However, the board of EEC is aware of the conflict of interest and has established a committee of directors independent of the Trusts management and excluding Mr. Conrad, to review all material matters related to its business dealings with Petroflow and to approve any material decisions relating thereto.  In addition, at each meeting of the board of EEC, management is required to report on all material matters relating to the business relationship with Petroflow.  Day-to-day oversight of the Petroflow farm-in, including decisions related to the specific location and timing of wells, has been delegated to a five person committee consisting of two representatives of Petroflow and three senior managers of the Trust.

Relationship with Macon Resources Ltd.

Mr. Conrad was not an employee of Enterra.  He provided his services as President and Chief Executive Officer of EEC pursuant to a management agreement that we entered into with Macon Resources Ltd. which was terminated November 2007.  Pursuant to the management agreement, we paid fees to Macon Resources Ltd. in the amount of $33,000 per month and provided office space for approximately 12 employees of Macon Resources Ltd. during the term of that agreement.  Of the $0.7 million paid to Macon during 2007, an agreed amount of $0.3 million related to the termination of the contract that otherwise would have run to June 1, 2008.

Macon Resources Ltd. also provided the services of the Vice President and Chief Financial Officer of the Trust from June 1, 2005 until June 15, 2006 in exchange for a fee of $17,000 per month.

Relationship with Trigger Projects Ltd.

On November 23, 2007, the Trust entered into a consulting agreement with Trigger Projects Ltd. for management services that would effectively be expected of the most senior manager of the Trust.  These services are performed by Don Klapko.  This contract has terms that require payment for services of $40,000 per month and a bonus of up to $0.5 million on termination.  The contract expires on May 31, 2008.  Payments of $50,000 were made to Trigger Projects Ltd. under this contract during 2007.

Other Management and Director Interests

Ms. Kim Booth, former Vice President and Chief Operating Officer, U.S. Operations, owns working interests ranging from 0.5% to 2.0% in approximately 45 wells on our Oklahoma properties.  Ms. Booth owned those interests prior to our acquisition of crude oil and natural gas properties located in Oklahoma.  Ms. Booth is not entitled to additional interests or new interests in any wells drilled on our Oklahoma properties.

Mr. W. Cobb (Chip) Hazelrig, a former director of EEC, has entered into a participation agreement dated March 1, 2006 (the Participation Agreement) with Enterra US Acqco whereby Mr. Hazelrig may, subsequent to March 1, 2006, elect to participate with Enterra US Acqco in the drilling of oil and gas wells on lands situated in Alfalfa, Garfield, Grant, Lincoln, Logan, Noble and Payne Counties, Oklahoma.  Upon the drilling of wells that Mr. Hazelrig has elected to participate in, assuming fulfillment by Mr. Hazelrig of his obligations pursuant to the Participation Agreement, including paying his proportionate share of all costs, expenses, responsibilities and liabilities in respect of the acquiring, maintaining and drilling such wells, Mr. Hazelrig will be entitled to an undivided 2.0% of the working interest owned by Enterra US Acqco in and to each of the oil, gas and mineral leases affected by or attributable to such wells.

As of the date hereof, none of McDaniel, Haas or MHA or any of their designated professionals owns directly or indirectly, any Trust Units.  Our auditors, KPMG LLP, have confirmed that they are independent within the meaning of the Rules of Professional Conduct of the Institute of Chartered Accountants of Alberta.



AUDIT COMMITTEE

General

EEC has established an Audit Committee (the Audit Committee) comprised of three members:  Vick Dusik, Roger Giovanetto and Michael Doyle, each of whom is considered independent and financially literate within the meaning of Multilateral Instrument 52-110  Audit Committees.

Mandate of the Audit Committee

The mandate of the Audit Committee is to assist the board of EEC in its oversight of the integrity of our financial and related information, including the financial statements, internal controls and procedures for financial reporting and the processes for monitoring compliance with legal and regulatory requirements.  In doing so, the Audit Committee oversees the audit efforts of our external auditors and, in that regard, is empowered to take such actions as it may deem necessary to satisfy itself that our external auditors are independent of us.

The Audit Committees function is oversight.  Management of EEC is responsible for the preparation, presentation and integrity of the financial statements of the Trust.  Management is responsible for maintaining appropriate accounting and financial reporting principles and policy and internal controls and procedures that provide for compliance with accounting standards and applicable laws and regulations.

While the Audit Committee has the responsibilities and powers set forth above, it is not the duty of the Audit Committee to plan or conduct audits or to determine whether the financial statements of the Trust are complete and accurate and are in accordance with generally accepted accounting principles.  This is the responsibility of management and the external auditors, on whom the members of the Committee are entitled to rely in good faith.

The mandate of the Audit Committee is attached hereto as Appendix A.

Relevant Education and Experience of Audit Committee Members

The following is a brief summary of the education or experience of each member of the Audit Committee that is relevant to the performance of his responsibilities as a member of the Audit Committee, including any education or experience that has provided the member with an understanding of the accounting principles used by us to prepare our annual and interim financial statements.

On March 20, 2000, Niaski Environmental Inc., which Mr. Conrad was then an insider and control person, made a proposal to its creditors under the Bankruptcy Act, which was approved by the creditors on April 13, 2000.
