Subject to the consent and cooperation of third parties, American will assist Enerplus in Enerplus’s efforts to obtain, at Enerplus’s expense, such additional information from third parties as Enerplus may reasonably request, for the purposes of Enerplus’s due diligence review. Enerplus may inspect the Records and such additional information only to the extent such inspection does not violate any contractual commitment of American to an unaffiliated third party. American shall make reasonable efforts to obtain consent from any such third party to disclose the information and Records to Enerplus, provided that Enerplus agrees to keep same confidential and not disclose it to anyone other than its advisors in this transaction, and provided further that American shall have no obligation to make any payment to obtain such consent.

Enerplus waives, releases and agrees to indemnify American, and its respective directors, officers, shareholders, members, employees, agents and representatives against all liabilities and obligations, including without limitation, personal injury, death and/or property damage, arising from Enerplus’s activities on the Assets except to the extent such liability or damages are caused by American’s willful misconduct. The provisions of this Section shall survive termination of this Agreement.

ARTICLE III
TITLE MATTERS

3.1 Definitions.

(a) Defensible Title. “Defensible Title” means such record title to the Leases that (i) would lead a reasonable prudent operator to distribute to American not less than the net revenue interest set forth on Schedule 1.2(a) for each Lease (“NRI”); (ii) would lead a reasonable prudent operator to xxxx American for costs and expenses relating to the maintenance, development, and operation of xxxxx located on the Leases in an amount not greater than the working interest set forth in Schedule 1.2(a) (“WI”); and (iii) is free and clear of encumbrances, liens and defects, other than Permitted Encumbrances.

(b) Permitted Encumbrances. “Permitted Encumbrances” means:

(1) lessors’ royalties, overriding royalties, net profits interests, production payments, reversionary interests and similar burdens (payable or in suspense) if the net cumulative effect of such burdens does not operate to reduce the NRI;

(2) liens for Taxes [as defined in Section 8.1(a)], or assessments not yet due and delinquent or, if delinquent, that are being contested in good faith in the normal course of business and if so required by statute for which bond has been posted;

(3) all required notices, consents, actions, or filings with any governmental agency related to conveyance of the applicable Lease, if the same are customarily obtained after Closing;

(4) rights of reassignment upon the surrender or expiration of any Lease;

(5) easements, rights-of-way, servitudes, permits, surface leases and other surface rights on or over the Leases or any restrictions on access thereto that do not materially interfere with the operation of the affected Lease as they have been conducted in the past;

(6) materialmen’s, mechanics’, operators’ or other similar liens arising in the ordinary course of business incidental to operation of the Leases (i) if such liens and charges have not been filed pursuant to law and the time for filing such liens and charges has expired, (ii) if filed, such liens and charges have not yet become due and payable or

payment is being withheld as provided by law, or (iii) if their validity is being contested in good faith by appropriate action; and

(7) depth limitations on American’s ownership of leasehold interests.

(c) Title Defect. “Title Defect” means any lien, encumbrance, claim, defect in or objection to real property title, other than Permitted Encumbrances, that alone or in combination with other defects (i) renders American’s title to the Lease less than Defensible Title and that (ii) reduces the Allocated Value of the affected Lease by more than $5,000.

(d) Title Defect Value. “Title Defect Value” means the amount by which the Allocated Value of a Lease is reduced by a Title Defect, although the Title Defect Value may never exceed the Allocated Value of the Lease. The Title Defect Value shall be determined by the Parties as follows:

(1) If the Title Defect is an indebtedness secured by a lien or encumbrance on a Lease that may be discharged in full by the satisfaction of such indebtedness, the Title Defect Value shall be the total amount to discharge such indebtedness so that such lien or encumbrance no longer burdens the Lease.

(2) If the Title Defect is an actual reduction in NRI with no change in WI, the Title Defect Value shall be the Allocated Value for the particular Lease, proportionately reduced by the ratio of the actual NRI to the NRI as set forth on Schedule 1.2(a).

(3) If the Title Defect does not fall into Section (1) or (2), then the Title Defect Value shall be determined by the Parties in good faith, taking into account all relevant factors, including without limitation, the following:

(i) The Allocated Value of the affected Lease;

(ii) If the Title Defect represents only a possibility of title failure, the probability that such failure will occur; and

(iii) The legal effect of the Title Defect.

(e) Title Disputes. Any dispute between American and Enerplus concerning the existence, nature or extent of a Title Defect, the Title Defect Value, or the adequacy of curative work performed in respect of such Title Defect shall be resolved as provided in Section 14.8, below.

3.2 Purchase Price Adjustments for Title Defects.

(a) Notice of Title Defects. Enerplus may give American written “Title Defect Notice” as soon as reasonably possible but no later than Tuesday, March 28, 2006 at 5:00 p.m. Mountain Time (“Title Defect Notice Date”). The Title Defect Notice must be in writing, name the affected Lease, describe each Title Defect and its basis in reasonable detail, state Enerplus’s good faith estimate of the Title Defect Value, and, if applicable, contain the information required by Section 3.2(b).

(b) Defect Adjustments. No adjustments to the Purchase Price shall be made unless and until the aggregate Title Defect Value exceeds $150,000.00. In its Title Defect Notice,

Enerplus shall identify Leases of its choice (the “Included Leases”) that suffer Title Defects in an amount equal to the lesser of (i) the aggregate Title Defect Value of all uncured Title Defects or (ii) $150,000.00. American shall be under no obligation to cure Title Defects in the Included Leases; instead, American’s entire interest in all of the Included Leases shall be assigned to Enerplus at Closing, without any reduction in the Purchase Price and without any continuing liabilitry or responsibility on the part of American in respect of such Title Defects. If, however, the aggregate value of all uncured Title Defects exceeds $150,000.00, then, only as to Leases suffering from Title Defects that are not Included Leases, each such Lease will not be assigned to Enerplus at Closing and the Purchase Price will be reduced at Closing by the Title Defect Value, unless (i) American elects to cure the Title Defect prior to Closing, (ii) Enerplus agrees to waive the relevant Title Defect, (iii) American elects on or before Closing to cure such Title Defect no later than 90 days after Closing, or (iv) American, with Enerplus’s consent, elects on or before Closing to indemnify Enerplus against any loss attributable to the relevant Title Defect.

(1) If American elects to cure the applicable Title Defect post-Closing, then Enerplus shall, pending such post Closing period, withhold and retain from the Purchase Price payable at Closing an amount equal to the Title Defect Value attributable to the affected Lease and American shall not assign the affected Lease to Enerplus at Closing.

(2) If American elects to cure the applicable Title Defect post-Closing, but does not cure the applicable Title Defect to Enerplus’s reasonable satisfaction within the 90 day time period (or such longer period as may be agreed to by the Parties), Enerplus may waive the applicable Title Defect, or if Enerplus does not waive the Title Defect, then, the Purchase Price shall be adjusted for the Title Defect Value of the affected Lease in accordance with the terms of this Agreement. If American cures the applicable Title Defect to Enerplus’s reasonable satisfaction within the 90-day time period (or such longer period as may be agreed to by the Parties), Enerplus shall pay to American the Title Defect Value attributable to the affected Lease and American shall assign such Lease to Enerplus.

3.3 Casualty Loss. Prior to Closing, if a portion of the Assets is destroyed by fire or other casualty (“Casualty Loss”), Enerplus shall purchase the Asset at Closing for the Allocated Value of the Asset reduced by the estimated cost to Enerplus for repair of such Asset (with equipment of similar utility) up to the Allocated Value thereof net of any payments as may be received from American’s insurers and paid to Enerplus attributable to any applicable insurance claims made on such Casualty Loss (the net reduction being the “Net Casualty Loss”). American, at its sole option, may elect to cure such Casualty Loss by replacing any personal property that is the subject of a Casualty Loss with equipment of equal (or better if American elects in its sole discretion) grade and utility and, if American elects to so cure the Casualty Loss, Enerplus shall purchase the affected Asset at Closing for the Allocated Value thereof.

3.4 Preferential Rights and Consents. Schedule 3.4 identifies preferential purchase rights and Required Consents. “Required Consents” are consents that, if not obtained by Closing, would invalidate the conveyance of an Asset; provided, however, that consents and approvals customarily obtained after Closing (such as federal and state approvals of assignments), and consents that do not specifically invalidate the conveyance if not obtained are not Required Consents. American shall use reasonable efforts to obtain all Required Consents and to give notices required in connection with preferential purchase rights prior to Closing. If, before Closing, Enerplus discovers other Required Consents or preferential purchase rights, Enerplus shall notify American immediately and American shall use

reasonable efforts to obtain such consents and to give the notices required in connection with the preferential rights prior to Closing.

(a) Consents. If a Required Consent has not been obtained by Closing, then (i) the portion of the Assets for which such consent has not been obtained shall not be conveyed at the Closing, (ii) the Allocated Value for that Asset shall not be paid to American, and (iii) American shall use reasonable efforts to obtain such consent as promptly as possible after Closing. If such consent has been obtained as of the Final Settlement Date, American shall convey the affected Asset to Enerplus effective as of the Effective Time and Enerplus shall pay American the Allocated Value of the affected Asset, together with any proceeds from the affected Asset attributable to the period of time after the Effective Time. If such consent has not been obtained as of the Final Settlement Date, American shall retain such Asset. Enerplus shall reasonably cooperate with American in obtaining any Required Consent, including providing assurance of financial condition, but Enerplus shall not be required to expend funds or make any other type of financial commitment as a condition of obtaining such consent.

(b) Preferential Purchase Rights.

(1) If any preferential right to purchase any portion of the Assets is exercised prior to the Closing Date, or if the time for exercise of such preferential purchase rights has not expired and American has not received notice of an intent not to exercise or otherwise to waive the preferential purchase right, that portion of the Assets affected by the preferential purchase right shall be excluded from the Assets and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such affected Assets.

(2) If a third party exercises its preferential right to purchase, but fails to consummate the transaction prior to the Closing, American shall retain the affected Asset and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such affected Assets.

(3) If a third party exercises its preferential right to purchase, but does not consummate the transaction within the time specified in the preferential purchase right, provided that the reason therefor is not American’s fault, American shall convey the affected Asset to Enerplus as soon as possible after the expiration of the time for consummation of the transaction, effective as of the Effective Time, and Enerplus shall pay American the Allocated Value of the affected Asset.

(4) If a preferential purchase right is not discovered before Closing and the affected Asset is conveyed to Enerplus at Closing, and if the preferential purchase right is later exercised, then Enerplus agrees to convey the affected Asset to the party exercising such right on the same terms and conditions under which American conveyed such Asset to Enerplus (with the purchase price being the Allocated Value for the affected Asset) and retain all amounts paid by the party exercising such preferential right to purchase. In the event of such exercise, Enerplus shall prepare, execute and deliver an appropriate form of conveyance of such Asset to the exercising party, and American agrees to hold harmless and indemnify Enerplus from any and all Losses, liabilities and obligations associated with such conveyed Asset, including, without limitation, any deficiency in the amount paid by such third party below the Allocated Value, if any, of the Asset.

(c) Remedies. The remedies set forth in this Section 3.4 are the exclusive remedies for the preferential purchase rights and Required Consents as listed on Schedule 3.4.

“Environmental Defect” means a condition in, on or under the Asset (including, without limitation, air, land, soil, surface and subsurface strata, surface water and ground water) that (i) causes an Asset to be in material violation of an Environmental Law or (ii) would give rise to a claim for damages by a third party.

“Environmental Defect Notice” means a written notice of an Environmental Defect, as more specifically described in Section 4.3, made by Enerplus to American, on or before the Environmental Defect Notice Date.

“Environmental Defect Notice Date” means Tuesday, March 28, 2006 at 5:00 p.m. Mountain Time.

“Environmental Law” means any statute, law, ordinance, rule, regulation, code, order, judicial writ, injunction, or decree issued by any federal, state, or local governmental authority including common law, in effect on or before the Effective Time relating to the control of any pollutant or protection of the air, water, land, or environment or the release or disposal of hazardous materials, hazardous substances or waste materials.

“Remediation” means actions taken to correct an Environmental Defect as recommended by an Environmental Consultant.

“Remediation Costs” means the costs or estimates thereof, to remediate a particular Environmental Defect, as estimated in writing by an Environmental Consultant.

4.2 Environmental Liabilities and Obligations.

(a) Retained Environmental Liabilities.

Timely receipt of a valid and complete Environmental Defect Notice is a condition precedent to American’s obligations under this Section.

(b) Assumed Environmental Liabilities. Except for Retained Environmental Liabilities and subject to the provisions of Section 4.4 and Article XIII, upon Closing, Enerplus agrees to assume and pay, perform, fulfill and discharge and release American from all Losses

relating to environmental conditions in, on or under the Assets attributable to the period of time before and after the Effective Time, including without limitation any and all liability for naturally occurring radioactive materials and man-made material fibers, and the obligation to plug and abandon all of the Xxxxx and reclamation of existing Well sites (collectively, “Assumed Environmental Liabilities”). Assumed Environmental Liabilities shall include any and all claims, costs, expenses, liabilities, and obligations attributable to the environmental condition of the Assets that were not the subject of a valid Environmental Defect Notice.

4.3 Environmental Defect Notice. An Environmental Defect Notice must be in writing and received on or before the Environmental Defect Notice Date, name the affected Asset and identify the condition in, on or under the Asset that causes the Environmental Defect, and contain a written statement of the estimated Remediation Costs by an Environmental Consultant.

4.4 Remedies for Environmental Defects. If Enerplus delivers a valid and complete Environmental Defect Notice to American, American may elect one of the following options: (i) American remediates the Environmental Defect, such remediation to be consistent with Environmental Laws; or (ii) American contests the existence of the Environmental Defect or the Remediation Costs in accordance with Section 4.5; or (iii) American pays Enerplus’s estimate of the Remediation Cost (“Environmental Defect Adjustment”). If American elects one of the foregoing three alternatives in respect of a particular Environmental Defect, American shall have no Retained Environmental Liability as to that Environmental Defect.

4.5 Contested Environmental Defects. If American contests the existence of an Environmental Defect or the Remediation Costs, American shall notify Enerplus in writing on or before ten days after receipt of the Environmental Defect Notice (“Rejection Notice”). The Rejection Notice shall state with reasonable specificity the basis of the rejection of the Environmental Defect or the Remediation Costs. Within 5 days of receipt of the Rejection Notice, representatives of Enerplus and American knowledgeable in environmental matters, shall meet and either (i) mutually agree to reject the particular Environmental Defect or (ii) agree on the validity of such Environmental Defect and the Remediation Costs. If the Parties cannot agree on either option (i) or (ii) in the preceding sentence, the Environmental Defect and/or the Remediation Costs subject to the Rejection Notice shall be resolved as provided in Section 14.8, below. If American fails timely to deliver a Rejection Notice, American shall be deemed to have accepted the validity of the Environmental Defect and Enerplus’s estimate of the Remediation Costs, and shall be deemed to have waived its own option to contest the Environmental Defect pursuant to this Section.

4.6 Exclusive Remedies. The rights and remedies granted each Party in this Article, together with the indemnifications set forth in Article XIII, are the exclusive rights and remedies against the other Party related to any Environmental matter, including, without limitation, Environmental Defects.

Unless American obtains the prior written consent of Enerplus to act otherwise, American will use good-faith efforts within the constraints of the applicable operating agreements and other applicable agreements and affording Enerplus’s representatives sufficient information and time to reasonably respond, not to (i) abandon any part of the Assets (except in the ordinary course of business or the abandonment of leases upon the expiration of their respective primary terms or if not capable of production in paying quantities), (ii) approve any operations on the Assets anticipated in any instance to cost the owner of the Assets more than $50,000 per activity (excepting emergency operations, operations required under presently existing contractual obligations, ongoing commitments under existing AFEs and operations undertaken to avoid a monetary penalty or forfeiture provision of any applicable

agreement or order), (iii) convey or dispose of any part of the Assets (other than replacement of equipment or sale of oil, gas, and other liquid products produced from the Assets in the regular course of business) or enter into any new farmout, farmin or other similar contract affecting the Assets, (iv) let lapse any insurance now in force with respect to the Assets, (v) modify or terminate any contract relating to the operation of the Assets, or (vi) enter into any new contracts without prior approval of Enerplus’s representatives.

(c) Notices of Claims. American shall promptly notify Enerplus, if, between the date of execution of this Agreement and the Closing Date, American receives written notice of any claim, suit, action or other proceeding or written notice of any material default under any Material Agreement.

7.2 Covenants and Agreements of Both Parties. Each Party covenants and agrees with the other as follows:

(a) Confidentiality. Until the closing (and thereafter, if Closing should not accur for any reason) all data and information, whether written or oral, obtained from American in connection with the transaction contemplated by this Agreement, whether before or after the execution of this Agreement, and data and information generated by Enerplus in connection with this transaction (collectively, the “Information”), is deemed by the Parties to be confidential and proprietary to American. Until the Closing (and thereafter, if Closing should not occur for any reason), except as required by law, Enerplus and its officers, agents and representatives will hold in strict confidence the terms of this Agreement, and all Information, except any Information which: (1) at the time of disclosure to Enerplus by American is in the public domain; (2) after disclosure to Enerplus by American becomes part of the public domain by publication or otherwise, except by breach of this commitment by Enerplus; (3) Enerplus can establish by competent proof was rightfully in its possession at the time of its disclosure to Enerplus by American; (4) Enerplus rightfully receives from third parties free of any obligation of confidence; or (5) is disclosed to Enerplus’s consultants, investors and lenders and those engaged by Enerplus to operate the Assets who similarly agree in writing to protect the confidentiality of such Information and agree to use such Information only for their due diligence evaluation of the Assets.

(b) Return of Information. If the transaction contemplated by this Agreement does not close on or before April 14, 2006, for reasons other than American’s wrongful breach of this Agreement under circumstances where, Enerplus is, but for such breach, ready to close, if American so requests at any time, Enerplus shall (i) return to American all copies of the Information in possession of Enerplus obtained pursuant to any provision of this Agreement, which Information is at the time of termination required to be held in confidence pursuant to Section 7.3(a); (ii) not utilize or permit utilization of the Information to compete with American; and (iii) destroy any and all notes, reports, studies or analyses based on or generated when incorporating or analyzing the Information. The terms of Sections 7.2(a) and (b) shall survive termination of this Agreement.

(c) Communication Between The Parties. If one Party develops information during its due diligence that leads it to believe that the other Party may have breached a representation or warranty under this Agreement, the Party discovering the potential breach shall promptly inform the other Party of such potential breach so that it may attempt to remedy or cure such breach prior to Closing.

(d) Cure Period for Breach. If any Party believes any other Party has breached the terms of this Agreement, the Party who believes the breach has occurred shall give written notice to the breaching Party of the nature of the breach and give that Party 48 hours to cure. Notwithstanding the foregoing, this Section 7.2(d) shall not apply to breach of the Parties’ obligations at Closing and shall not operate to delay Closing.

ARTICLE VIII
TAX MATTERS

8.1 Apportionment of Tax Liability.

(a) Liability for Oil and Gas Taxes. “Taxes” shall mean all ad valorem, property, production, excise, net proceeds, severance and all other taxes and similar obligations (including penalties) assessed against the Assets or based upon or measured by the ownership of the Assets or the production of Hydrocarbons or the receipt of proceeds therefrom, other than income taxes or other taxes levied or assessed against American. All Taxes based or calculated on production of hydrocarbons shall be deemed attributable to the period during which such production occurred and not during the period such Taxes are assessed. With respect to the Assets, all Taxes shall be prorated between Enerplus and American as of the Effective Time for all taxable periods that include the Effective Time; i.e., American shall be responsible for all Taxes for ownership of the Assets prior to the Effective Time, and Enerplus shall be responsible for all Taxes for assessed ownership of the Assets after the Effective Time. Accordingly, for the Assets, (i) Enerplus expressly assumes all obligations and liabilities for all Taxes related to the Assets that are attributable to the period of time after the Effective Time and (ii) American expressly retains all obligations and liabilities for all Taxes related to the Assets that are attributable to the period prior to the Effective Time.

(b) Liability for Income and Other Taxes. Except Taxes allocated to Enerplus pursuant to Section 8.1(a), American expressly retains and indemnifies Enerplus for all taxes levied and assessed against American with respect to the Assets, or otherwise, such taxes to include without limitation, federal, state, local or foreign income taxes, gross receipts, license, withholding, payroll, employment or other taxes (with such Taxes being “Other Taxes”).

8.2 Calculation of Tax Liability. Consistent with Section 8.1, and based on the best current information available as of Closing, the proration of Taxes shall be made between the Parties as an adjustment to the Purchase Price pursuant to Section 1.4 and thereafter from time to time as the Parties agree.

8.3 Tax Reports and Returns. For the tax period in which the Effective Time occurs, American agrees promptly to forward to Enerplus any such tax reports and returns received by American after Closing and provide Enerplus with appropriate information which is necessary for Enerplus to file any required tax reports and returns related to the Assets. Enerplus agrees to file all tax returns and reports applicable to the Assets that are required to be filed after the Closing, and pay all required Taxes payable with respect to the Assets subject to the provisions of Section 8.1.

8.4 Sales Taxes. Enerplus shall be liable for and shall indemnify American for any sales and use taxes, conveyance, transfer and recording fees and real estate transfer stamps or taxes that may be imposed on any transfer of the Assets pursuant to this Agreement. If required by applicable law, American shall, in accordance with applicable law, calculate and remit any sales or similar taxes that are required to be paid as a result of the transfer of the Assets to Enerplus and Enerplus shall promptly

reimburse American therefor. If American receives notice that any sales and/or use taxes are due, American shall promptly forward such notice to Enerplus for handling.

As soon as practicable after the Closing, but in no event later than Friday, May 26, 2006, American will prepare and deliver to Enerplus, in accordance with customary industry accounting practices, the final settlement statement (the “Final Settlement Statement”) setting forth each adjustment or payment that was not finally determined as of the Closing and showing the calculation of such adjustment and the resulting final purchase price (the “Final Purchase Price”). As soon as practicable after receipt of the Final Settlement Statement, but in no event later than on or before Friday, June 9, 2006, Enerplus shall deliver to American a written report containing any changes that Enerplus proposes to make to the Final Settlement Statement. Enerplus’s failure to deliver to American a written report detailing proposed changes to the Final Settlement Statement by that date shall be deemed an acceptance by Enerplus of the Final Settlement Statement as submitted by American. The Parties shall agree with respect to the changes proposed by Enerplus, if any, no later than Friday, June 16, 2006. The Final Settlement Statement shall set forth the “Second Closing Amount” and all adjustments to the Purchase Price and associated calculations. The date upon which such agreement is reached or upon which the Final Purchase Price is established shall be herein called the “Final Settlement Date.” Enerplus agrees to pay American the Second Closing Amount on Friday, July 14, 2006. For a period of six months following the Closing, Enerplus agrees to provide American monthly with copies of joint interest xxxxxxxx and revenue remittances received from the operator of the Assets.

12.2 Records. American agrees to make the Records available for pick up by Enerplus as soon as is reasonably practical, but in any event within seven days after Closing. American may retain copies of the Records and American shall have the right to review and copy the Records during standard business hours upon reasonable notice for so long as Enerplus retains the Records. Enerplus agrees that the Records will be maintained in compliance with all applicable laws governing document retention. Enerplus will not destroy or otherwise dispose of Records after Closing, unless Enerplus first gives American reasonable notice and an opportunity to copy the Records to be destroyed. If and to the extent certain portions of the Records are subject to unaffiliated third party contractual restrictions on disclosure or transfer, American agrees to use reasonable efforts to obtain the waiver of such contractual restrictions; provided, however, that American shall not be required to expend any money in connection with obtaining such waivers.

13.1 Enerplus’s Assumption of Liabilities and Obligations. Upon Closing and subject to the provisions of Section 12.3, and except for Retained Liabilities, Enerplus shall assume and pay, perform, fulfill and discharge of all claims, costs, expenses, liabilities and obligations attributable to the (i) the Assumed Environmental Liabilities and (ii) the Assets and the period of time after the Effective Time, including, without limitation the following as they relate to the period of time after the Effective Date: (a) the Agreements, (b) all liability for royalty and overriding royalty payments and Taxes made with respect to the Assets, (c) the payment of Property Expenses, and (d) the obligation to plug and abandon all xxxxx located on the Lands and reclaim all Well sites located on the Lands (collectively, the “Assumed Liabilities”).

13.2 American’s Retention of Liabilities and Obligations. Upon Closing and subject to the provisions of Section 12.3, American shall retain all claims, costs, expenses, liabilities and obligations accruing or relating to (i) the Retained Environmental Liabilities, (ii) the Other Taxes, and (iii) the Assets and period of time prior to the Effective Time, including without limitation, the following as they relate to the period of time prior to the Effective Time: (a) the liability for royalty and overriding royalty payments and Taxes made with respect to the Assets and (b) any injury, death, casualty, or tortious action occurring on or attributable to the Assets (the “Retained Liabilities”).

By assuming or retaining liabilities or obligations in Sections 13.1 or 13.2, American and Enerplus do not intend to, and shall not be deemed by any third parties to, have admitted any liability for the period of time before American owned the Assets.

13.3 Indemnification. “Losses” shall mean any actual losses, costs, expenses (including court costs, reasonable fees and expenses of attorneys, technical experts and expert witnesses and the cost of investigation), liabilities, damages, demands, suits, claims, and sanctions of every kind and character (including civil fines) arising from, related to or reasonably incident to matters indemnified against; excluding however any special, consequential, punitive or exemplary damages, loss of profits incurred by a Party hereto or Loss incurred as a result of the indemnified Party indemnifying a third party.

After the Closing, the Parties shall indemnify each other as follows:

(a) American’s Indemnification of Enerplus. American assumes all risk, liability, obligation and Losses in connection with, and shall defend, indemnify, and save and hold harmless Enerplus, its partners and all officers, directors, employees and agents of Enerplus and its partners, from and against all Losses which arise from or in connection with (i) the Retained Liabilities and (ii) any matter for which American has specifically agreed to indemnify Enerplus under this Agreement.

(b) Enerplus’s Indemnification of American. Enerplus assumes all risk, liability, obligation and Losses in connection with, and shall defend, indemnify, and save and hold harmless American, its officers, directors, employees and agents, from and against all Losses which arise from or in connection with (i) the Assumed Liabilities and (ii) any matter for which Enerplus has specifically agreed to indemnify American under this Agreement.

(c) Release. Enerplus shall be deemed to have released American at the Closing from any Losses for which Enerplus has agreed to indemnify American hereunder, and American shall be deemed to have released Enerplus at the Closing from any Losses for which American has agreed to indemnify Enerplus hereunder.

13.4 Procedure. The indemnifications contained in Section 13.3 shall be implemented as follows:

(a) Coverage. Such indemnity shall extend to all Losses suffered or incurred by the indemnified Party.

(b) Claim Notice. The Party seeking indemnification under the terms of this Agreement (“Indemnified Party”) shall submit a written “Claim Notice” to the other Party (“Indemnifying Party”) which, to be effective, must state: (i) the amount of each payment claimed by an Indemnified Party to be owing, (ii) the basis for such claim, with supporting documentation, and (iii) a list identifying to the extent reasonably possible each separate item of Loss for which payment is so claimed. The amount claimed shall be paid by the Indemnifying Party to the extent required herein within 30 days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs.

(c) Information. Within 60 days after the Indemnified Party receives notice of a claim or legal action that may result in a Loss for which indemnification may be sought under this Article XIII (a “Claim”), the Indemnified Party shall give written notice of such Claim to the Indemnifying Party. If the Indemnifying Party or its counsel so requests, the Indemnified Party shall furnish the Indemnifying Party with copies of all pleadings and other information with respect to such Claim. At the election of the Indemnifying Party made within 60 days after receipt of such notice, the Indemnified Party shall permit the Indemnifying Party to assume control of such Claim (to the extent only that such Claim, legal action or other matter relates to a Loss for which the Indemnifying Party is liable), including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and the conduct of litigation through attorneys of the Indemnifying Party’s choice; provided, however, that no such settlement can result in any liability or cost to the Indemnified Party for which it is entitled to be indemnified hereunder without its consent. If the Indemnifying Party elects to assume control, (i) any expense incurred by the Indemnified Party thereafter for investigation or defense of the matter shall be borne by the Indemnified Party, and (ii) the Indemnified Party shall give all reasonable information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such Claim, legal action, or other matter. In the absence of such an election, the Indemnified Party will use its best efforts to defend, at the Indemnifying Party’s expense, any claim, legal action or other matter to which such other Party’s indemnification under this Article XIII applies until the Indemnifying Party assumes such defense, and, if the Indemnifying Party fails to assume such defense within the time period provided above, settle the same in the Indemnified Party’s reasonable discretion at the Indemnifying Party’s expense. If such a Claim requires immediate action, both the Indemnified Party and the Indemnifying Party will cooperate in good faith to take appropriate action so as not to jeopardize defense of such Claim or either Party’s position with respect to such Claim.

13.5 No Insurance; Subrogation. The indemnifications provided in this Article XIII shall not be construed as a form of insurance. Enerplus and American hereby waive for themselves, their successors or assigns, including, without limitation, any insurers, any rights to subrogation for Losses for which each of them is respectively liable or against which each respectively indemnifies the other, and, if required by applicable policies, Enerplus and American shall obtain waiver of such subrogation from their respective insurers.

13.6 Reservation as to Non-Parties. Nothing herein is intended to limit or otherwise waive any recourse Enerplus or American may have against any non-party for any obligations or liabilities that may be incurred with respect to the Assets.
