-13-

DBJV Assets were used and operated by DBJV immediately prior to the Closing Date. A true and complete list of all DBJV Surface Contracts involving an annual payment in excess of $1 million and all property owned by DBJV in fee is set forth on Schedule 4.6(b). The Seller has provided true, correct and complete copies of all material DBJV Surface Contracts to the Buyer.

The Tax Partnership is properly treated as a partnership for federal income tax purposes. The classification for federal income tax purposes of DBJV will not change after the Closing by reason of any action taken by the Seller on or before the Closing Date or by reason of any action taken on or before the Closing Date by any Person who was at the time such action was taken an Affiliate of the Seller.

ARTICLE VIII

TERMINATION

Section 8.1 Termination.

(a) Right to Terminate. This Agreement may be terminated and the transactions contemplated hereby abandoned at any time prior to the Closing:

(i) by mutual written consent of Anadarko and the Partnership;

(ii) by either Anadarko or the Partnership if the Closing has not occurred within 90 days of the date of this Agreement (the “Termination Date”); provided, however, that this right to terminate this Agreement shall not be available to any Party whose breach of this Agreement or whose Affiliate’s breach of this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before such date;

(iii) by either Anadarko or the Partnership if a Governmental Entity shall have issued an Order or taken any other action, in each case permanently restraining, enjoining, or otherwise prohibiting the transactions contemplated by this Agreement; or

(iv) by Anadarko in the event of a breach by the Buyer, or by the Partnership in the event of a breach by Anadarko or the Seller, of any representation, warranty, covenant or other agreement contained in this Agreement which (A) would give rise to the failure of a condition set forth in Section 7.2(b), Section 7.2(c), Section 7.2(e), Section 7.3(a) or Section 7.3(b), as applicable, and (B) cannot be or has not been cured by the earlier of (x) 20 days following receipt by the breaching party of written notice of such breach or (y) the Business Day immediately preceding the Termination Date.

(b) Effect of Investigation. The right of any Party to terminate this Agreement pursuant to this Section 8.1 shall remain operative and in full force and effect regardless of the actual or constructive knowledge of such Party regarding the subject matter giving rise to such right of termination.

Section 8.2 Effect of Termination. Upon termination of this Agreement pursuant to Section 8.1, the undertakings of the Parties set forth in this Agreement shall forthwith be of no further force and effect; provided, however, that no such termination shall relieve any Party of any intentional material breach of any term or provision hereof.

ARTICLE IX

INDEMNIFICATION

Section 9.1 Survival.

(a) The representations and warranties in this Agreement shall survive the Closing until the applicable dates specified in Sections 9.1(b) and 9.1(c) and regardless of

-24-

any inspection or investigation by or on behalf of the Buyer or the Seller, respectively; provided that any representation or warranty with respect to which a claim for indemnification has been brought pursuant to this Article IX that is pending at the end of the applicable survival period shall continue to survive until the final resolution of such claim.

(b) The liability of Anadarko and the Seller for the breach of any of the representations and warranties of Anadarko and the Seller set forth in Article IV shall be limited to claims for which a Partnership Indemnified Party delivers written notice to Anadarko on or before the date that is 18 months after the Closing Date; provided, however, that (i) the representations and warranties in Section 4.9 shall be limited to claims for which a Partnership Indemnified Party delivers written notice to Anadarko on or before the date that is 24 months after the Closing Date; and (ii) the representations and warranties set forth in Sections 4.1, 4.2, 4.6 and 4.7 shall not be limited as to time other than the applicable statute of limitations.

(c) The liability of the Buyer for the breach of any of the representations and warranties of the Buyer set forth in Article V shall be limited to claims for which an Anadarko Indemnified Party delivers written notice to the Partnership on or before 18 months after the Closing Date; provided, however, that the representations and warranties set forth in Sections 5.1 and 5.2 shall not be limited as to time other than the applicable statute of limitations.

Section 9.2 Indemnification of the Anadarko Indemnified Parties. Solely for the purpose of indemnification in this Section 9.2, the representations and warranties of the Buyer in this Agreement shall be deemed to have been made without regard to any materiality or Material Adverse Effect qualifiers. The Partnership, from and after the Closing Date, shall indemnify and hold Anadarko, the Seller and their respective Affiliates (other than any of the Partnership Entities), shareholders, unitholders, members, directors, officers, employees, agents and representatives (together with Anadarko and the Seller, the “Anadarko Indemnified Parties”) harmless from and against any and all Losses, suffered or incurred by the Anadarko Indemnified Parties as a result of, caused by, arising out of, or in any way relating to (a) subject to Section 9.1, any breach of a representation or warranty of the Buyer in this Agreement, and (b) any breach of any agreement or covenant on the part of the Buyer in this Agreement.

Section 9.3 Indemnification of the Partnership Indemnified Parties. Solely for the purpose of indemnification in this Section 9.3, the representations and warranties of Anadarko and the Seller in this Agreement shall be deemed to have been made without regard to any materiality or Material Adverse Effect qualifiers. Anadarko shall indemnify and hold the Buyer, the Partnership and their respective Affiliates (other than any of the Anadarko Entities), shareholders, unitholders, members, directors, officers, employees, agents and representatives (together with the Buyer and the Partnership, the “Partnership Indemnified Parties”) harmless from and against any and all Losses suffered or incurred by the Partnership Indemnified Parties as a result of, caused by, arising out of, or in any way relating to:

(a) subject to Section 9.1, any breach of a representation or warranty of Anadarko or the Seller in this Agreement;

-25-

(b) any breach of any agreement or covenant on the part of Anadarko or the Seller in this Agreement;

(c) any Taxes imposed on or incurred by DBJV, the Tax Partnership or related to the DBJV Assets with respect to any Pre-Closing Tax Period and the portion of any Straddle Period ending on the Closing Date, or with respect to the matters on Schedule 9.3(e);

(d) the failure to obtain, make or comply with any DBJV Asset Required Consents; and

(e) the matters set forth on Schedule 4.5 and Schedule 9.3(e).

Section 9.4 Demands. The Indemnified Party agrees that within 30 days after it becomes aware of facts giving rise to a claim for indemnification pursuant to this Article IX, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial or otherwise, by any third party (any such third party action being referred to herein as the “Indemnity Claim”), with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will provide notice thereof in writing to the Indemnifying Party specifying in reasonable detail the nature of and specific basis for such claim. Notwithstanding the foregoing, the Indemnified Party’s failure to provide notice under this Section 9.4 will not relieve the Indemnifying Party from the liability hereunder with respect to such matter except in the event and only to the extent that the Indemnifying Party is materially prejudiced by such failure or delay. Such notice shall include a formal demand for indemnification under this Agreement.

Section 9.5 Right to Contest and Defend. The Indemnifying Party shall be entitled at its cost and expense to contest and defend by all appropriate legal proceedings any Indemnity Claim with respect to which it is called upon to indemnify the Indemnified Party under the provisions of this Agreement; provided that notice of the intention to so contest shall be delivered by the Indemnifying Party to the Indemnified Party within 20 days from the date of receipt by the Indemnifying Party of notice by the Indemnified Party of the assertion of the Indemnity Claim. Any such contest may be conducted in the name and on behalf of the Indemnifying Party or the Indemnified Party as may be appropriate. Such contest shall be conducted by reputable counsel (in the reasonable opinion of the Indemnifying Party) employed by the Indemnifying Party and not reasonably objected to by the Indemnified Party, but the Indemnified Party shall have the right but not the obligation to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense. The Indemnifying Party shall have full authority to determine all action to be taken with respect such proceedings; provided, however, that the Indemnifying Party will not have the authority to subject the Indemnified Party to any obligation whatsoever, other than the performance of purely ministerial tasks or obligations not involving material expense. If the Indemnifying Party does not elect to contest any such Indemnity Claim, the Indemnifying Party shall be bound by the result obtained with respect to such claim by the Indemnified Party. If the Indemnifying Party shall have assumed the defense of an Indemnity Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of an Indemnity Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the

-26-

liability in connection with such Indemnity Claim, which fully and completely releases the Indemnified Party in connection with such Indemnity Claim and which would not otherwise adversely affect the Indemnified Party.

Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Indemnity Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the Indemnified Party in defending such Indemnity Claim) if the Indemnity Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnified Party which the Indemnified Party reasonably determines, upon the advice of outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or other relief portion of the Indemnity Claim can be so separated from that for money damages, the Indemnifying Party shall be entitled to assume the defense of the portion relating to money damages.

Section 9.6 Cooperation. The Indemnified Party agrees to cooperate with the Indemnifying Party with respect to all aspects of the defense of any Indemnity Claims covered by the indemnification set forth in this Article IX, including the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the names of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party reasonably considers relevant to such defense and the making available to the Indemnifying Party of any employees of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 9.6, unless otherwise required by Law or the listing standards of the New York Stock Exchange or any other applicable exchange or quotation system. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article IX; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party reasonably informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense to the extent provided above.

Section 9.7 Payment of Losses. The indemnification required hereunder shall be made by monthly payments of the amount thereof during the course of the investigation or defense, within 30 days as and when reasonably specific bills are received or Loss is incurred and reasonable evidence thereof is delivered. In calculating any amount to be paid by an Indemnifying Party by reason of the indemnification provisions of this Agreement, the amount to be paid shall be reduced by (i) any insurance proceeds related to indemnified Losses realized by the Indemnified Party and (ii) any amounts related to indemnified Losses recovered by the Indemnified Party under contractual indemnities from third parties.

-27-

Section 9.8 Limitations on Indemnification.

(a) To the extent the Partnership Indemnified Parties are entitled to indemnification for Losses pursuant to Section 9.3(a) (other than for Losses related to a breach of the representations and warranties in Section 4.6), Anadarko shall not be liable for those Losses unless the aggregate amount of Losses exceeds $3,000,000 (the “Deductible”), and then only to the extent of any such excess.

(b) In addition, to the extent the Partnership Indemnified Parties are entitled to indemnification for Losses pursuant to Section 9.3(a), Anadarko shall not be liable for such Losses that exceed, in the aggregate, $75,000,000 less the Deductible.

(c) Notwithstanding Section 9.8(a) and (b), to the extent the Partnership Indemnified Parties are entitled to indemnification for Losses arising from a breach of the representations and warranties in Section 4.6, pursuant to Section 9.3(b), 9.3(c), 9.3(d), or 9.3(e), or for claims arising from fraud, Anadarko shall be fully liable for such Losses without respect to the Deductible in Section 9.8(a) and the limitations in Section 9.8(b).

(d) To the extent the Anadarko Indemnified Parties are entitled to indemnification for Losses pursuant to Section 9.2(a), the Partnership shall not be liable for those Losses unless the aggregate amount of Losses exceeds, in the aggregate, the Deductible, and then only to the extent of any such excess. In addition, to the extent the Anadarko Indemnified Parties are entitled to indemnification for Losses pursuant to Section 9.2(a), the Partnership shall not be liable for such Losses that exceed, in the aggregate, $30,000,000 less the Deductible.

(e) Notwithstanding Section 9.8(d), to the extent the Anadarko Indemnified Parties are entitled to indemnification for Losses pursuant to Section 9.2(b) or for claims arising from fraud, the Partnership shall be fully liable for such Losses without respect to the Deductible and the limitations in Section 9.8(d).

Section 9.9 Sole Remedy. Notwithstanding anything herein to the contrary, after the Closing, this Article IX contains the Anadarko Indemnified Parties’ and the Partnership Indemnified Parties’ exclusive remedy against each other with respect to breaches of the representations, warranties, covenants and agreements of the Parties contained in Article IV and Article V and in the covenants in this Agreement to be performed prior to the Closing, in each case other than claims or causes of action arising from fraud. All references in this Article IX to such breaches of such representations, warranties, covenants and agreements include any affirmation of such representations, warranties, covenants and agreements contained in the certificates delivered at Closing by the Seller pursuant to Section 3.2(b) or by the Buyer pursuant to Section 3.3(b).

Section 9.10 Express Negligence Rule. THE INDEMNIFICATION PROVISIONS PROVIDED FOR IN THIS AGREEMENT HAVE BEEN EXPRESSLY NEGOTIATED IN EVERY DETAIL, ARE INTENDED TO BE GIVEN FULL AND LITERAL EFFECT, AND SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, OBLIGATIONS, CLAIMS, JUDGMENTS, LOSSES, COSTS, EXPENSES OR DAMAGES IN QUESTION ARISE OR AROSE SOLELY OR IN PART FROM THE GROSS, ACTIVE, PASSIVE OR CONCURRENT

-▇▇-

▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇ LIABILITY, OR OTHER FAULT OF ANY INDEMNIFIED PARTY. ANADARKO AND THE SELLER AND THE BUYER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND CONSTITUTES CONSPICUOUS NOTICE. NOTICE IN THIS CONSPICUOUS NOTICE IS NOT INTENDED TO PROVIDE OR ALTER THE RIGHTS AND OBLIGATIONS OF ANADARKO AND THE PARTIES, ALL OF WHICH ARE SPECIFIED ELSEWHERE IN THIS AGREEMENT.

After the Closing, each Party shall take such further actions, including obtaining consents to assignment from third parties, and execute such further documents as may be necessary or reasonably requested by the other Parties in order to effectuate the intent of this Agreement and the Ancillary Documents and to provide such other Parties with the intended benefits of this Agreement and the Ancillary Documents.
