The Asset Allocation shall be used for purposes of determining the aggregate deemed sales price and adjusted grossed-up basis under the applicable Treasury Regulations and in reporting the deemed sale of assets of the Company in connection with the Section 338(h)(10) Elections. Purchaser, Seller and their respective Affiliates hereby agree that they will report the federal, state, foreign and other tax consequences of the transactions contemplated by this Agreement in a manner consistent with the Section 338(h)(10) Elections and the Asset Allocation.

(c) Purchaser shall be responsible for the preparation of all forms and documents required in connection with the Section 338(h)(10) Elections. Purchaser, Seller and their respective Affiliates shall timely file all forms required to be filed to make the Section 338(h)(10) Elections and shall provide each other with evidence that such filings have been made. Seller and/or its Affiliates shall execute and deliver to Purchaser such documents or forms consistent with the Asset Allocation (including Section 338 Forms, as defined below) as Purchaser shall request or as are required by applicable Law for an effective Section 338(h)(10) Election. “Section 338 Forms” shall mean all returns, documents, statements, and other forms that are required to be submitted to any federal, state, county or other local taxing authority in connection with a Section 338(h)(10) Election, including any “statement of Section 338 election” and Internal Revenue Service Forms 8023 and 8883 (together with any schedules or attachments thereto) that are required pursuant to the Treasury Regulations.

(d) Purchaser shall indemnify Seller from and against any increase in Taxes payable by Seller due to the Section 338(h)(10) Elections. The indemnification shall be in an amount equal to the quotient of (i) the Taxes paid by Seller with respect to the sale of the Shares with the Section 338(h)(10) Election minus the taxes which would have been paid by the Seller with respect to the sale of the Shares without the Section 338(h)(10) Elections, divided by (ii) 1 minus the sum of the federal income tax rate on capital gains plus the state income tax rate on capital gains plus the local income tax rate on capital gains applicable to Seller at the time indemnification payments are made under this Section 8.9(d). For purposes of calculating the amount of Taxes payable by Seller or which would have been payable by Seller had the election not been made, such amounts will be calculated without regard to tax attributes or then-current year taxable income or loss attributable to any member of the Seller Group (other than the Company). For avoidance of doubt, if a member of the Seller Group (other than the Company) has tax deductions which reduce the taxes payable by the Seller, then such deduction shall not be used in calculating taxes payable by the Seller for purposes of this Section. Purchaser shall indemnify Seller within thirty (30) days following Purchaser’s receipt of the submission by Seller to Purchaser of written calculations of the indemnification amount, supported by either (i) the actual tax returns of Seller, (ii) assessment of taxes by any Governmental Authority, or (iii) the Section 338 Forms and a calculation of the Company’s adjusted tax basis of its properties certified by an officer of the Seller and pro forma calculations of taxes which Seller would have paid with respect to the sale of the Shares without the Section 338(h)(10) Elections. Purchaser’s indemnification obligation under this Section 8.9(d) shall survive Closing and continue in effect until ninety (90) days following the expiration of the statute of limitations on all federal, state and local Taxes for any and all years in which payments of Adjusted Purchase Price are made under this Agreement. Purchaser’s indemnification obligations under this Section 8.9(d) shall not be subject to and shall not be limited by Article X.

This Agreement may be terminated at any time prior to Closing: (a) by the mutual prior written consent of the Parties, or the prior written agreement of Purchaser and the Seller; (b) by either Seller or Purchaser by notice to the other pursuant to Section 7.5; or (c) by either Seller or Purchaser by notice to the other if Closing has not occurred on or before one hundred eighty (180) days from the date of this Agreement or such other date as may be agreed to in writing by the Parties, provided, however, that no Party shall be entitled to terminate this Agreement under this Section 9.1(c) if Closing has failed to occur because such Party negligently or willfully failed to perform or observe in any material respect its covenants and agreements hereunder.

In the event of termination of this Agreement by Seller under Section 9.1(c) due to non-satisfaction of a closing condition set out in Section 6.1, Purchaser shall have no liability whatsoever to Seller, notwithstanding anything to the contrary in this Agreement. Termination of this Agreement by either Party under Section 9.1(c) shall not relieve the other Party from liability for any willful or negligent failure to perform or observe in any material respect any of its agreements or covenants contained herein that are to be performed or observed at or prior to Closing, and in such event, the first-mentioned Party shall be entitled to all remedies available at law or in equity, and shall be entitled to recover court costs, attorneys’ fees and any other relief to which such Party may be entitled.

ARTICLE 10. INDEMNIFICATION; LIMITATIONS

  Section 10.1Indemnification.

(a)From and after Closing, Purchaser shall indemnify, defend and hold harmless Seller from and against all Damages:

(i)caused by or arising out of or resulting from the condition, ownership, use or operation of the Assets or ownership of any of the Shares, whether before or after the Effective Time or the Closing Date (unless such Damages are the result of a breach of a representation or warranty by Seller as set forth in Section 10.1(e));

(ii)caused by or arising out of or resulting from Purchaser’s breach of any of Purchaser’s covenants or agreements contained in Article 5; or

(iii)caused by or arising out of or resulting from any breach of any representation or warranty made by Purchaser contained in Article 4 or in the certificate delivered by Purchaser at Closing pursuant to Section 7.3(c);

(b)Except as provided for in Section 10.1(e), Purchaser releases, remises and forever discharges Seller and its Affiliates and all such Persons’ stockholders, officers, directors, trustees, employees, agents, advisors and representatives from any and all suits, legal or administrative proceedings, claims, demands, damages, losses, costs, liabilities, interest or causes of action whatsoever, at law or in equity, known or unknown, which Purchaser might now or subsequently may have, based on, relating to or arising out of this Agreement, the Shares of the Company or the Company’s ownership, use or operation of the Assets or the condition of the Assets, including any rights under insurance policies issued or underwritten by Seller or any of its Affiliates and any rights under agreements between the Company and Seller or any other Affiliate of the Company. Notwithstanding the foregoing, Purchaser and its heirs, legal representatives, successors and assignees retain, and do not release, their rights and interests under this Agreement and any documents to be delivered as set out herein.

32

(c)“Damages”, for purposes of this Agreement, shall mean the amount of any actual liability, loss, cost, expense, claim, award or judgment incurred or suffered by any Indemnified Person arising out of or resulting from the indemnified matter, whether attributable to personal injury or death, property damage, contract claims, torts or otherwise including reasonable fees and expenses of attorneys, consultants, accountants or other agents and experts reasonably incident to matters indemnified against, and the costs of investigation and/or monitoring of such matters, and the costs of enforcement of the indemnity; provided, however, that no Party shall be entitled to indemnification under this Section 10.1 for, and “Damages” shall not include: (i) any loss of profits, other indirect or consequential damages, special damages, exemplary damages or punitive damages except those payable to third Persons; or (ii) any liability, loss, cost, expense, claim, award or judgment to the extent resulting from or increased by the actions or omissions of any Indemnified Person after the Closing Date.

(d)The indemnities to which each Party is entitled under this Section 10.1 shall be for the benefit of and extend to such Party’s present and former Affiliates, and all of its respective directors, officers, employees and agents. Any claim for indemnity under this Section 10.1 by any such Affiliate, director, officer, employee or agent must be brought and administered by the relevant Party on behalf of such Indemnified Person. No Indemnified Person other than a Party hereto shall have any rights against any Party under the terms of this Section 10.1 except as may be exercised on its behalf by the relevant Party pursuant to this Section 10.1(d). A Party may elect to exercise or not exercise indemnification rights under this Section on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section.

(e)Subject to the limitations provided in this Section 10.1 and Section 10.3, in the event Seller breaches any of its representations and warranties contained in Sections 3.2 through 3.22 herein or in the certificate delivered by Seller at Closing pursuant to Section 7.2(d), or breaches any of its covenants and agreements contained in Article 5, and, provided that Purchaser makes a written claim for indemnification against Seller pursuant to Section 10.2 below within the survival period, then Seller shall be obligated to indemnify Purchaser from and against the entirety of any Damages Purchaser may suffer resulting from, arising out of, relating to, in the nature of, or caused by the breach (or the alleged breach); provided, however, (A) that Seller shall not have any obligation to indemnify Purchaser from and against any Damages resulting from, arising out of, relating to, in the nature of, or caused by the breach of any representation or warranty of Seller contained in Sections 3.2 through 3.22 (except for Section 3.16) until the Purchaser shall have suffered Damages by reason of all such breaches in excess of a $500,000 aggregate threshold (at which point Seller will be obligated to indemnify Purchaser from and against all such Damages), and (B) that the aggregate liability of the Seller under this Section 10.1(e) with respect to the representations and warranties contained in Sections 3.4 through 3.22 shall not exceed fifteen percent (15%) of the Adjusted Purchase Price and with respect to all other Damages shall not exceed the Adjusted Purchase Price. For the avoidance of doubt, all materiality qualifications contained in any of the representations and warranties made in Article 3 or Article 4 of this Agreement, and/or any document required to be executed and delivered as set out herein, including the term “Material Adverse Effect” will be taken into account in this Article 10 solely for purposes of determining whether a breach or violation of such representation or warranty has occurred for which an indemnity obligation exists. Without limiting the generality of the foregoing, all such materiality qualifications will be ignored and not given effect for the purposes of determining the amount of Damages for any such breach or violation.

33

  Section 10.2Indemnification Actions. All claims for indemnification under Section 10.1 shall be asserted and resolved as follows:

(a)To make claim for indemnification under Section 10.1, an Indemnified Person shall notify the Purchaser or Seller, as applicable (the “Indemnifying Person”) of its claim, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a third Person against the Indemnified Person (a “Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Claim and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Person to give notice of a Claim as provided in this Section 10.2 shall not relieve the Indemnifying Person of its obligations under Section 10.1 except to the extent such failure materially prejudices the Indemnifying Person's ability to defend against the Claim.

(b)In the case of a claim for indemnification based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Claim under this Article 10. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period regarding whether Purchaser admits or denies its obligation to defend the Indemnified Person, the Damages for which the Indemnified Person is seeking indemnity shall be conclusively deemed a liability of the Indemnifying Person hereunder. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(c)If the Indemnifying Person admits its obligation to indemnify the Indemnified Person, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim. The Indemnifying Person shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate in contesting any Claim which the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Person may participate in, but not control, any defense or settlement of any Claim controlled by the Indemnifying Person pursuant to this Section 10.2(c). The Indemnifying Person shall not, without the written consent of the Indemnified Person, such consent not to be unreasonably withheld, settle any Claim or consent to the entry of any judgment with respect thereto that: (i) does not result in a final resolution of the Indemnified Person’s liability with respect to the Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all liability in respect of such Claim); or (ii) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

34

(d)If the Indemnifying Person does not admit its obligation to indemnify the Indemnified Person or admits its obligation but fails to diligently defend or settle the Claim, the Indemnified Person shall have the right to defend against the Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Person to admit its obligation to indemnify the Indemnified Person and assume the defense of the Claim at any time prior to the settlement or the final determination thereof. If the Indemnifying Person has not yet admitted its obligation to indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for ten (10) days following receipt of such notice to: (i) admit in writing its obligation for indemnification with respect to such Claim; and (ii) if its obligation is so admitted, assume the defense of the Claim, including the power to reject the proposed settlement. If the Indemnified Person settles any Claim over the objection of the Indemnifying Person after the Indemnifying Person has timely admitted its obligation for indemnification in writing and assumed the defense of the Claim, the Indemnified Person shall be deemed to have waived any right to indemnity for such Claim hereunder.

(e)In the case of a claim for indemnification not based upon a Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to: (i) cure the Damages complained of; (ii) admit its obligation to indemnify the Indemnified Person for such Damages; or (iii) dispute the Indemnified Person’s claim for such Damages. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period that it has cured the Damages or that it disputes the claim for such Damages, the amount of such Damages shall conclusively be deemed an obligation of the Indemnifying Person hereunder.

Section 10.3Limitation on Actions.

(a)All of the representations and warranties of the Parties contained in this Agreement shall survive Closing and continue in full force and effect for a period of eighteen (18) months thereafter; provided, however, that the representations and warranties in Sections 3.1, 3.2(a)-(c), 3.2(e), 3.3(a)-(b), 3.3(d)-(p), 3.16, 4.1, 4.2, 4.3 and 4.5 through 4.11 shall survive without limitation as to time. Covenants shall survive Closing in accordance with their terms and any covenants or agreements contained in this Agreement that by their terms are to be performed after Closing shall survive until fully discharged. Notwithstanding the foregoing, there shall be no termination of any bona fide claim asserted by Seller pursuant to this Agreement with respect to a representation, warranty, covenant or agreement of Purchaser prior to its expiration date.

(b)The indemnities in Sections 10.1(a)(ii), 10.1(a)(iii) and 10.1(e) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Party on or before such termination date. The indemnity in Section 10.1(a)(i) shall continue without time limit.

(c)The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 10 shall be reduced by the amount of insurance proceeds realized by the Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates).

Section 10.4Exclusive Remedy.

The indemnification provisions of this Article 10 and Section 8.9 shall, following Closing, be the sole remedy for the parties hereto for enforcement of the provisions of this Agreement, including claims for any breach, default or other violation of the terms of this Agreement.

HOUSTON, Texas - September 27, 2007 - Ultra Petroleum Corp.
