PIONEER SOUTHWEST ENERGY PARTNERS L.P. INDEMNIFICATION AGREEMENT

This Agreement (“Agreement”) is made and entered into as of the 7th day of March, 2013, by and between Pioneer Southwest Energy Partners L.P., a Delaware limited partnership (the “Partnership”), and Phillip A. Gobe (“Indemnitee”).

A.    Highly competent and experienced persons are reluctant to serve companies as directors, executive officers or in other capacities unless they are provided with adequate protection through insurance and indemnification against claims and actions against them arising out of their service to and activities on behalf of the company.

B.    The Board of Directors (the “Board”) of Pioneer Natural Resources GP LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), has determined that the inability to attract and retain such persons would be detrimental to the best interests of the Partnership and its unitholders and that the Partnership should act to assure such persons that there will be increased certainty of such protection in the future.

C.    The Board has also determined that it is reasonable, prudent and necessary for the Partnership, in addition to purchasing and maintaining directors’ and officers’ liability insurance (or otherwise providing for adequate arrangements of self-insurance), contractually to obligate itself to indemnify such persons to the fullest extent permitted by the Partnership Agreement (as hereinafter defined) so that they will serve or continue to serve the General Partner and the Partnership free from undue concern that they will not be adequately protected.

D.    Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the General Partner and the Partnership on the condition that Indemnitee be so indemnified to the fullest extent permitted by the Partnership Agreement.

E.    Section 7.7 of the First Amended and Restated Agreement of Limited Partnership of the Partnership (the “Partnership Agreement”) provides for indemnification of directors and officers.

F.    Indemnitee is an “Indemnitee” as such term is defined in the Partnership Agreement.

In consideration of the foregoing and the mutual covenants herein contained, and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereby agree as follows:

As used herein, the following words and terms shall have the following respective meanings (whether singular or plural):

“Affiliate” means, with respect to any Person, any other Person that directly or indirectly through one or more intermediaries controls, is controlled by or is under common control with the Person in question.

Should any payments by the Partnership under this Agreement be determined to be subject to any federal, state or local income or excise tax, “Expenses” shall also include such amounts as are necessary to place Indemnitee in the same after-tax position (after giving effect to all applicable taxes) as Indemnitee would have been in had no such tax been determined to apply to such payments. Also, in this Agreement “witness” includes responding (or objecting) to a discovery request, whether in writing or in an oral deposition, in any Proceeding.

Indemnitee and the Partnership each acknowledge that they have entered into this Agreement as a means of inducing Indemnitee to serve, or continue to serve, the General Partner in such capacities. Indemnitee may at any time and for any reason resign from such position or positions (subject to any other contractual obligation or any obligation imposed by operation of law). Neither the General Partner nor the Partnership shall have any obligation under this Agreement to continue Indemnitee in any such position or positions.

Section 3.1    General. Subject to the provisions set forth in Article IV, the Partnership shall indemnify, and advance Expenses to, Indemnitee to the fullest extent permitted by the Partnership Agreement on the date hereof and to such greater extent as the Partnership Agreement

may hereafter from time to time permit. The other provisions set forth in this Agreement are provided in addition to and as a means of furtherance and implementation of, and not in limitation of, the obligations and limitations expressed in this Article III. No requirement, condition to or limitation of any right to indemnification or to advancement of Expenses under this Article III shall in any way limit the rights of Indemnitee under Article VII.

Section 3.2    Additional Indemnity of the Partnership. Indemnitee shall be entitled to indemnification pursuant to this Section 3.2 if, by reason of anything done or not done by Indemnitee in, or by reason of any event or occurrence related to, Indemnitee’s Status, Indemnitee is, was or becomes, or is threatened to be made, a party to, or witness or other participant in any Proceeding. Pursuant to this Section 3.2, Indemnitee shall be indemnified against any and all Expenses, judgments, penalties (including excise or similar taxes), fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any such Expenses, judgments, penalties, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any Claim, issue or matter therein. Notwithstanding the foregoing, the obligations of the Partnership under this Section 3.2 shall be subject to the condition that no determination (which, in any case in which Independent Counsel is involved, shall be in a form of a written opinion) shall have been made pursuant to Article IV or Article V that Indemnitee would not be permitted to be indemnified under the Partnership Agreement. Nothing in this Section 3.2 shall limit the benefits of Section 3.1, Section 3.3 or any other Section hereunder.

Section 3.3    Advancement of Expenses. The Partnership shall pay all Expenses reasonably incurred by, or in the case of retainers to be incurred by, or on behalf of Indemnitee (or, if applicable, reimburse Indemnitee for any and all Expenses reasonably incurred by Indemnitee and previously paid by Indemnitee) in connection with any Claim or Proceeding, whether brought by the Partnership or otherwise, in advance of any determination respecting entitlement to indemnification pursuant to Article IV hereof (and shall continue to pay such Expenses after such determination and until it shall ultimately be determined (in a final adjudication by a court from which there is no further right of appeal or in a final adjudication of an arbitration pursuant to Section 5.1 if Indemnitee elects to seek such arbitration) that Indemnitee is not entitled to be indemnified by the Partnership against such Expenses) within 10 days after the receipt by the Partnership of (a) a written request from Indemnitee requesting such payment or payments from time to time, whether prior to or after final disposition of such Claim or Proceeding and (b) a written affirmation from Indemnitee of Indemnitee’s good faith belief that Indemnitee has met the standard of conduct necessary for Indemnitee to be permitted to be indemnified under applicable law. Any such payment by the Partnership is referred to in this Agreement as an “Expense Advance.” In connection with any request for an Expense Advance, if requested by the Partnership, Indemnitee or Indemnitee’s counsel shall also submit an affidavit stating that the Expenses incurred were, or in the case of retainers to be incurred are, reasonably incurred. Any dispute as to the reasonableness of the incurrence of any Expense shall not delay an Expense Advance by the Partnership, and the Partnership agrees that any such dispute shall be resolved only upon the disposition or conclusion of the underlying Claim against Indemnitee. Indemnitee hereby undertakes and agrees that Indemnitee will reimburse and repay the Partnership without interest for any Expense Advances to the extent that it shall ultimately be determined (in a final adjudication by a court from which there

is no further right of appeal or in a final adjudication of an arbitration pursuant to Section 5.1 if Indemnitee elects to seek such arbitration) that Indemnitee is not entitled to be indemnified by the Partnership against such Expenses. Indemnitee shall not be required to provide collateral or otherwise secure the undertaking and agreement described in the prior sentence. The Partnership shall make all Expense Advances pursuant to this Section 3.3 without regard to the financial ability of the Indemnitee to make repayment and without regard to the prospect of whether the Indemnitee may ultimately be found to be entitled to indemnification under the provisions of this Agreement.

Section 3.4    Indemnification for Additional Expenses. The Partnership shall indemnify Indemnitee against any and all costs and expenses (of the types described in the definition of Expenses in Article I) and, if requested by Indemnitee, shall (within two business days of that request) advance those costs and expenses to Indemnitee, that are incurred by Indemnitee in connection with any claim asserted against, or action brought by, Indemnitee for (i) indemnification or an Expense Advance by the Partnership under this Agreement or any other agreement or provision of the Partnership Agreement now or hereafter in effect relating to any Claim or Proceeding, (ii) recovery under any directors’ and officers’ liability insurance policies maintained by the Partnership, or (iii) enforcement of, or claims for breaches of, any provision of this Agreement, in each of the foregoing situations regardless of whether Indemnitee ultimately is determined to be entitled to that indemnification, Expense Advances payment, insurance recovery, enforcement, or damage claim, as the case may be, and regardless of whether the nature of the proceeding with respect to such matters is judicial, by arbitration, or otherwise.

Section 3.5    Partial Indemnity. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Partnership for some or a portion of the Expenses, judgments, fines, penalties, and amounts paid in settlement of a Claim or Proceeding but not, however, for all of the total amount thereof, the Partnership shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. Moreover, notwithstanding any other provision of this Agreement, to the extent that Indemnitee has been successful on the merits or otherwise in defense of any or all Claims or Proceedings, or in defense of any issue or matter therein, including dismissal without prejudice, Indemnitee shall be indemnified against all Expenses incurred in connection therewith.

Section 4.1    Request by Indemnitee. To obtain indemnification under this Agreement, Indemnitee shall submit to the Partnership a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the General Partner shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Nevertheless, any failure of Indemnitee to provide a request to the Partnership, or to provide such a request timely, shall not

relieve the Partnership of any liability that it may have to Indemnitee hereunder except, and to the extent that, such failure actually and materially prejudices the interests of the Partnership.

Section 4.2    Determination of Request. Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 4.1 hereof, a determination, if required by applicable law, with respect to whether Indemnitee is permitted under Article III to be indemnified shall be made in accordance with the terms of Section 4.5, in the specific case as follows:

(a)    If a Potential Change in Control or a Change in Control shall have occurred, by Independent Counsel (selected in accordance with Section 4.3) in a written opinion to the Board and Indemnitee, unless Indemnitee shall request that such determination be made by the Board, or a committee of the Board, in which case by the person or persons or in the manner provided for in clause (i) or (ii) of paragraph (b) below; or

(b)    If a Potential Change in Control or a Change in Control shall not have occurred, (i) by the Board by a majority vote of the Disinterested Directors even though less than a quorum of the Board, or (ii) by a majority vote of a committee consisting solely of two or more Disinterested Directors designated to act in the matter by a majority vote of all Disinterested Directors even though less than a quorum of the Board, or (iii) by Independent Counsel selected by the Board or a committee of the Board by a vote as set forth in clauses (i) or (ii) of this paragraph (b), or if such vote is not obtainable or such a committee cannot be established, by a majority vote of all directors, or (iv) if Indemnitee and the Partnership agree, by the unitholders of the Partnership in a vote that excludes the units held by directors who are not Disinterested Directors.

If it is so determined that Indemnitee is permitted to be indemnified under Article III, payment to Indemnitee shall be made within 10 days after such determination. Nothing contained in this Agreement shall require that any determination be made under this Section 4.2 prior to the disposition or conclusion of a Claim or Proceeding against Indemnitee; provided, however, that Expense Advances shall continue to be made by the Partnership pursuant to, and to the extent required by, the provisions of Article III. Indemnitee shall cooperate with the person or persons making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person upon reasonable advance request any documentation or information that is not privileged or otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person or persons making such determination shall be borne by the Partnership (irrespective of the determination as to Indemnitee’s entitlement to indemnification), and the Partnership shall indemnify and hold harmless Indemnitee therefrom.

Section 4.3    Independent Counsel. If a Potential Change in Control or a Change in Control shall not have occurred and the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be selected by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board or (b) if there are no Disinterested Directors, by a majority vote of the Board, and the Partnership shall give written

notice to Indemnitee, within 10 days after receipt by the Partnership of Indemnitee’s request for indemnification, specifying the identity and address of the Independent Counsel so selected. If a Potential Change in Control or a Change in Control shall have occurred and the determination of entitlement to indemnification is to be made by Independent Counsel, the Independent Counsel shall be selected by Indemnitee, and Indemnitee shall give written notice to the Partnership, within 10 days after submission of Indemnitee’s request for indemnification, specifying the identity and address of the Independent Counsel so selected (unless Indemnitee shall request that such selection be made by the Disinterested Directors or a committee of the Board, in which event the Partnership shall give written notice to Indemnitee within 10 days after receipt of Indemnitee’s request for the Board or a committee of the Disinterested Directors to make such selection, specifying the identity and address of the Independent Counsel so selected). In either event, (i) such notice to Indemnitee or the Partnership, as the case may be, shall be accompanied by a written affirmation of the Independent Counsel so selected that it satisfies the requirements of the definition of “Independent Counsel” in Article I and that it agrees to serve in such capacity and (ii) Indemnitee or the Partnership, as the case may be, may, within seven days after such written notice of selection shall have been given, deliver to the Partnership or to Indemnitee, as the case may be, a written objection to such selection. Any objection to the selection of Independent Counsel pursuant to this Section 4.3 may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of the definition of “Independent Counsel” in Article I, and the objection shall set forth with particularity the factual basis of such assertion. If such written objection is timely made, the Independent Counsel so selected may not serve as Independent Counsel unless and until a court of competent jurisdiction (the “Court”) has determined that such objection is without merit or such objection is withdrawn. In the event of a timely written objection to a choice of Independent Counsel, the party originally selecting the Independent Counsel shall have seven days to make an alternate selection of Independent Counsel and to give written notice of such selection to the other party, after which time such other party shall have five days to make a written objection to such alternate selection. If, within 30 days after submission of Indemnitee’s request for indemnification pursuant to Section 4.1, no Independent Counsel shall have been selected and not objected to, either the Partnership or Indemnitee may petition the Court for resolution of any objection that shall have been made by the Partnership or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Court or by such other person as the Court shall designate, and the person with respect to whom an objection is so resolved or the person so appointed shall act as Independent Counsel under Section 4.2. The Partnership shall pay any and all fees of, and expenses reasonably incurred by, such Independent Counsel in connection with acting pursuant to Section 4.2, and the Partnership shall pay all fees and expenses reasonably incurred incident to the procedures of this Section 4.3, regardless of the manner in which such Independent Counsel was selected or appointed. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 5.1, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing).

Section 4.4    Establishment of a Trust. In the event of a Potential Change in Control or a Change in Control, the Partnership shall, upon written request by Indemnitee, create a trust for the benefit of Indemnitee (the “Trust”) and from time to time upon written request of Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all Expenses reasonably anticipated at the time of each such request to be incurred in connection with investigating, preparing for, and defending any Claim, and any and all judgments, fines, penalties, and settlement amounts of any and all Claims from time to time actually paid or claimed, reasonably anticipated, or proposed to be paid. The amount to be deposited in the Trust pursuant to the foregoing funding obligation shall be determined by the Independent Counsel (or other person(s) making the determination of whether Indemnitee is permitted to be indemnified by applicable law). The terms of the Trust shall provide that, upon a Change in Control, (i) the Trust shall not be revoked or the principal thereof invaded, without the written consent of Indemnitee; (ii) the trustee of the Trust shall advance to Indemnitee, within ten days of a request by Indemnitee, any and all Expenses reasonably incurred by, or in case of retainer to be incurred by, or on behalf of Indemnitee (or, if applicable, reimburse Indemnitee for any Expense reasonably incurred by Indemnitee and previously paid by Indemnitee), with any required determination concerning the reasonableness of the Expenses to be made by the Independent Counsel (and Indemnitee hereby agrees to reimburse the Trust under the circumstances in which Indemnitee would be required to reimburse the Partnership for Expense Advances under Section 3.3 of this Agreement); (iii) the Trust shall continue to be funded by the Partnership in accordance with the funding obligation set forth above; (iv) the trustee of the Trust shall promptly pay to Indemnitee all amounts for which Indemnitee shall be entitled to indemnification pursuant to this Agreement; and (v) all unexpended funds in the Trust shall revert to the Partnership upon a final determination by the Independent Counsel or a court of competent jurisdiction, as the case may be, that Indemnitee has been fully indemnified under the terms of this Agreement. The trustee of the Trust shall be chosen by Indemnitee and shall be an institution that is not affiliated with Indemnitee. Nothing in this Section 4.4 shall relieve the Partnership of any of its obligations under this Agreement.

Section 4.5    Presumptions and Effect of Certain Proceedings.

(a)    Indemnitee shall be presumed to be entitled to indemnification under this Agreement upon submission of a request for indemnification under Section 4.1, and the Partnership shall have the burden of proof in overcoming that presumption in reaching a determination contrary to that presumption. Such presumption shall be used by Independent Counsel (or other person or persons determining entitlement to indemnification) as a basis for a determination of entitlement to indemnification unless the Partnership provides information sufficient to overcome such presumption by clear and convincing evidence or unless the investigation, review and analysis of Independent Counsel (or such other person or persons) convinces Independent Counsel by clear and convincing evidence that the presumption should not apply.

(b)    If the person or persons empowered or selected under Article IV of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have

made a determination within 60 days after receipt by the Partnership of the request by Indemnitee therefor, the determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the person making the determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating to such determination; and provided, further, that the 60-day limitation set forth in this Section 4.5(b) shall not apply and such period shall be extended as necessary (i) if within 30 days after receipt by the Partnership of the request for indemnification under Section 4.1 Indemnitee and the Partnership have agreed, and the Board has resolved, to submit such determination to the unitholders of the Partnership pursuant to Section 4.2(b) for their consideration and a special meeting of unitholders is called within 30 days after such receipt for the purpose of making such determination, such meeting is held for such purpose within 60 days after having been so called and such determination is made thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 4.2(a) of this Agreement, in which case the applicable period shall be as set forth in Section 5.1(c).

(c)    The termination of any Proceeding or of any Claim, issue or matter by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) by itself adversely affect the rights of Indemnitee to indemnification or create a presumption that Indemnitee failed to meet any particular standard of conduct, that Indemnitee had any particular belief, or that a court has determined that indemnification is not permitted by the Partnership Agreement. Indemnitee shall be deemed to have been found liable in respect of any Claim, issue or matter only after Indemnitee shall have been so adjudged by the Court after exhaustion of all appeals therefrom.

(d)    For purposes of the second sentence of Section 3.5, a settlement or other resolution of a Proceeding short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. For purposes of the second sentence of Section 3.5, in the event that any Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including settlement of such Proceeding with or without payment of money or other consideration), it shall be presumed that Indemnitee has been successful on the merits or otherwise in such Proceeding. Anyone seeking to overcome this presumption shall have the burden of proof by clear and convincing evidence.

(e)    The failure of the Partnership (including by the directors of the General Partner or Independent Counsel) to have made a determination before the commencement of any action pursuant to this Agreement that indemnification is proper because Indemnitee has met the applicable standard of conduct shall not be a defense to the action or create a presumption that Indemnitee has not met the standard of conduct.

Section 5.1    Indemnitee Entitled to Adjudication in an Appropriate Court. If (1) a determination is made pursuant to Article IV that Indemnitee is not entitled to indemnification under this Agreement; (1) there has been any failure by the Partnership to make timely payment or advancement of any amounts due hereunder (including, without limitation, any Expense Advances); or (1) the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 4.2 and such determination shall not have been made and delivered in a written opinion within 90 days after the latest of (i) such Independent Counsel’s being appointed, (ii) the overruling by the Court of objections to such counsel’s selection, or (iii) expiration of all periods for the Partnership or Indemnitee to object to such counsel’s selection, Indemnitee shall be entitled to commence an action seeking an adjudication in the Court of Indemnitee’s entitlement to such indemnification or advancements due hereunder, including, without limitation, Expense Advances. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the commercial arbitration rules of the American Arbitration Association. Indemnitee shall commence such action seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such action pursuant to this Section 5.1, or such right shall expire. The Partnership agrees not to oppose Indemnitee’s right to seek any such adjudication or award in arbitration and it shall continue to pay Expense Advances pursuant to Section 3.3 until it shall ultimately be determined (in a final adjudication by a court from which there is no further right of appeal or in a final adjudication of an arbitration pursuant to this Section 5.1 if Indemnitee elects to seek such arbitration) that Indemnitee is not entitled to be indemnified by the Partnership against such Expenses.

Section 5.2    Adverse Determination Not to Affect any Judicial Proceeding. If a determination shall have been made pursuant to Article IV that Indemnitee is not entitled to indemnification under this Agreement, any judicial proceeding or arbitration commenced pursuant to this Article V shall be conducted in all respects as a de novo trial or arbitration on the merits, and Indemnitee shall not be prejudiced by reason of such initial adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Article V, Indemnitee shall be presumed to be entitled to indemnification or advancement of Expenses, as the case may be, under this Agreement and the Partnership shall have the burden of proof in overcoming such presumption and to show by clear and convincing evidence that Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be.

Section 5.3    Partnership Bound by Determination Favorable to Indemnitee in any Judicial Proceeding or Arbitration. If a determination shall have been made or deemed to have been made pursuant to Article IV that Indemnitee is entitled to indemnification, the Partnership shall be irrevocably bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Article V, and shall be precluded from asserting that such determination has not been made or that the procedure by which such determination was made is not valid, binding and enforceable.

Section 5.4    Partnership Bound by the Agreement. The Partnership shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Article V that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Partnership is bound by all the provisions of this Agreement. Without limiting the generality of the preceding sentence, the Partnership shall not seek from a court, or agree to, a “bar order” that would have the effect of prohibiting or limiting Indemnitee’s rights to advancement of any Expenses under this Agreement.

Section 6.1    Contribution Payment.

(a)    Whether or not the indemnification provided in Article III hereof is available, in respect of any threatened, pending or completed action, suit or Proceeding in which the Partnership is jointly liable with Indemnitee (or would be if joined in such action, or Proceeding), the Partnership shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or Proceeding without requiring Indemnitee to contribute to such payment, and the Partnership hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Partnership shall not enter into any settlement of any action, suit or Proceeding in which the Partnership is jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee.

(b)    Without diminishing or impairing the obligations of the Partnership set forth in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or Proceeding in which the Partnership is jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding), the Partnership shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Partnership and all officers, directors or employees of the General Partner, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction or events from which such action, suit or Proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the Partnership and all officers, directors or employees of the General Partner other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or Proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the transaction or events that resulted in such Expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable law may require to be considered.

(c)    The Partnership hereby agrees, to the fullest extent permitted by applicable law, to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by officers, directors or employees of the General Partner, other than Indemnitee, who may be jointly liable with Indemnitee.

(d)    To the fullest extent permissible under applicable law and without diminishing or impairing the obligations of the Partnership set forth in the preceding subparagraphs of this Section 6.1, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Partnership, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Partnership and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Partnership (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s).

Section 6.2    Relative Fault. The relative fault of the Indemnitee, on the one hand, and of the Partnership and any and all other parties (including officers and directors of the Partnership other than Indemnitee) who may be at fault with respect to such matter shall be determined (i) by reference to the relative fault of Indemnitee as determined by the court or other governmental agency assessing the contribution amounts or (ii) to the extent such court or other governmental agency does not apportion relative fault, by the Independent Counsel (or such other party which makes a determination under Article IV) after giving effect to, among other things, the degree of which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary, the degree to which their conduct is active or passive, the degree of the knowledge, access to information, and opportunity to prevent or correct the subject matter of the Proceedings and other relevant equitable considerations of each party. The Partnership and Indemnitee agree that it would not be just and equitable if contribution pursuant to this Section 6.2 were determined by pro rata allocation or by any other method of allocation which does take account of the equitable considerations referred to in this Section 6.2.

Section 7.1    Non-Exclusivity. The rights of Indemnitee to receive indemnification and advancement of Expenses under this Agreement shall be in addition to, and shall not be deemed exclusive of, any other rights Indemnitee shall have under the DLLCA, DRULPA or other applicable law, the certificate of formation and limited liability company agreement of the General Partner, the certificate of limited partnership of the Partnership and the Partnership Agreement, any other agreement, vote of members or unitholders or a resolution of directors, or otherwise. Every other right or remedy of Indemnitee shall be cumulative of the rights and remedies granted Indemnitee hereunder. No amendment or alteration of the certificate of formation and limited liability company

agreement of the General Partner, the certificate of limited partnership of the Partnership or the Partnership Agreement or any provision thereof shall adversely affect Indemnitee’s rights hereunder and such rights shall be in addition to any rights Indemnitee may have under the certificate of formation and limited liability company agreement of the General Partner, the certificate of limited partnership of the Partnership and the Partnership Agreement and the DLLCA, DRULPA or other applicable law. To the extent that there is a change in the DRULPA or other applicable law (whether by statute or judicial decision) that allows greater indemnification by agreement than would be afforded currently under the certificate of limited partnership of the Partnership and the Partnership Agreement and this Agreement, if permitted by the Partnership Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by virtue of this Agreement the greater benefit so afforded by such change. Any amendment, alteration or repeal of the DLLCA or DRULPA that adversely affects any right of Indemnitee shall be prospective only and shall not limit or eliminate any such right with respect to any Proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place before the effective date of such amendment or repeal.

Section 7.2    Insurance and Subrogation.

(a)    To the extent that the Partnership maintains an insurance policy or policies providing liability insurance for directors, officers, employees, agents or fiduciaries of the General Partner or the Partnership or for individuals serving at the request of the General Partner as directors, officers, partners, members, venturers, proprietors, trustees, employees, agents, fiduciaries or similar functionaries of another foreign or domestic corporation, partnership, limited liability company, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee, agent or fiduciary under such policy or policies.

(b)    In the event of any payment by the Partnership under this Agreement for which reimbursement is available under any insurance policy or policies obtained by the Partnership, the Partnership shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee under such insurance policy or policies, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Partnership to bring suit to enforce such rights, provided that all Expenses relating to such action shall be borne by the Partnership.

(c)    The Partnership shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under the Partnership’s certificate of limited partnership, the Partnership Agreement, or any insurance policy, contract, agreement or otherwise.

(d)    If Indemnitee is a director of the Company, the Company will advise the Board of any proposed material reduction in the coverage for Indemnitee to be provided by the Partnership’s directors’ liability insurance policy and will not effect such a reduction with respect to Indemnitee without the prior approval of at least 80% of the Independent Directors of the General Partner.

(e)    If Indemnitee is a director of the Company during the term of this Agreement and if Indemnitee ceases to be a director of the General Partner for any reason, the Partnership shall procure a run-off directors’ and officers’ liability insurance policy with respect to claims arising from facts or events that occurred before the time Indemnitee ceased to be a director of the General Partner and covering Indemnitee, which policy, without any lapse in coverage, will provide coverage for a period of six years after the time Indemnitee ceased to be a director of the General Partner and will provide coverage (including amount and type of coverage and size of deductibles) that are substantially comparable to the Partnership’s directors’ and officers’ liability insurance policy that was most protective of Indemnitee in the 12 months preceding the time Indemnitee ceased to be a director of the General Partner, provided, however, that:

(i)    this obligation shall be suspended during the period immediately following the time Indemnitee ceases to be a director of the General Partner if and only so long as the Partnership has a directors’ and officers’ liability insurance policy in effect covering Indemnitee for such claims that, if it were a run-off policy, would meet or exceed the foregoing standards, but in any event this suspension period shall end when a Change in Control occurs; and

(ii)    no later than the end of the suspension period provided in the preceding clause (i) (whether because of failure to have a policy meeting the foregoing standards or because a Change in Control occurs), the Partnership shall procure a run-off directors’ and officers’ liability insurance policy meeting the foregoing standards and lasting for the remainder of the six-year period.

(f)    Notwithstanding the preceding clause (e) including the suspension provisions therein, if Indemnitee ceases to be an officer or a director of the General Partner in connection with a Change in Control or at or during the one-year period following the occurrence of a Change in Control, the Partnership shall procure a run-off directors’ and officers’ liability insurance policy covering Indemnitee and meeting the foregoing standards in clause (e) and lasting for a six-year period upon the Indemnitee’s ceasing to be an officer or a director of the General Partner in such circumstances.

(g)    If at the time of the receipt of a notice of a Claim or Proceeding pursuant to the terms hereof, the Partnership has directors’ and officers’ liability insurance in effect, the Partnership shall give prompt notice of the commencement of such Claim or Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Partnership shall thereafter take all necessary or desirable action to cause such insurers to

pay, on behalf of the Indemnitee, all amounts payable as a result of such Claim or Proceeding in accordance with the terms of such policies.

Section 7.3    Self Insurance of the Partnership; Other Arrangements. The parties hereto recognize that the Partnership may, but except as provided in Section 7.2(d), Section 7.2(e), and Section 7.2(f) is not required to, procure or maintain insurance or other similar arrangements, at its expense, to protect itself and any person, including Indemnitee, who is or was a director, officer, employee, agent or fiduciary of the General Partner or the Partnership or who is or was serving at the request of the General Partner as a director, officer, partner, member, venturer, proprietor, trustee, employee, agent, fiduciary or similar functionary of another foreign or domestic corporation, partnership, limited liability company, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise against any expense, liability or loss asserted against or incurred by such person, in such a capacity or arising out of the person’s status as such a person, whether or not the Partnership would have the power to indemnify such person against such expense or liability or loss.

Except as provided in Section 7.2(d), Section 7.2(e) and Section 7.2(f), in considering the cost and availability of such insurance, the Partnership (through the exercise of the business judgment of the General Partner’s directors and officers) may, from time to time, purchase insurance which provides for certain (i) deductibles, (ii) limits on payments required to be made by the insurer, or (iii) coverage which may not be as comprehensive as that previously included in insurance purchased by the Partnership or its predecessors. The purchase of insurance with deductibles, limits on payments and coverage exclusions, even if in the best interest of the Partnership, may not be in the best interest of Indemnitee. As to the Partnership, purchasing insurance with deductibles, limits on payments and coverage exclusions is similar to the Partnership’s practice of self-insurance in other areas. In order to protect Indemnitee who would otherwise be more fully or entirely covered under such policies, the Partnership shall, to the maximum extent permitted by the Partnership Agreement, indemnify and hold Indemnitee harmless to the extent (i) of such deductibles, (ii) of amounts exceeding payments required to be made by an insurer, or (iii) of amounts that prior policies of directors’ and officers’ liability insurance held by the Partnership or its predecessors have provided for payment to Indemnitee, if by reason of Indemnitee’s Status Indemnitee is or is threatened to be made a party to any Proceeding. The obligation of the Partnership in the preceding sentence shall be without regard to whether the Partnership would otherwise be required to indemnify such officer or director under the other provisions of this Agreement, or under any law, agreement, vote of unitholders or directors or other arrangement. Without limiting the generality of any provision of this Agreement, the procedures in Article IV hereof shall, to the extent applicable, be used for determining entitlement to indemnification under this Section 7.3.

Section 7.4    Certain Settlement Provisions. The Partnership shall have no obligation to indemnify Indemnitee under this Agreement for amounts paid in settlement of a Proceeding or Claim without the Partnership’s prior written consent. The Partnership shall not settle any Proceeding or Claim in any manner that would impose any fine or other obligation on Indemnitee without Indemnitee’s prior written consent. Neither the Partnership nor Indemnitee shall unreasonably withhold their consent to any proposed settlement.

Section 7.5    Duration of Agreement. This Agreement shall continue for so long as Indemnitee serves as a director, officer, employee, agent or fiduciary of the General Partner or, at the request of the General Partner, as a director, officer, partner, member, venturer, proprietor, trustee, employee, agent, fiduciary or similar functionary of another foreign or domestic corporation, partnership, limited liability company, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise, and thereafter shall survive until and terminate upon the later to occur of: (a) the expiration of 20 years after the latest date that Indemnitee shall have ceased to serve in any such capacity; (b) the final termination of all pending Proceedings in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to Article V relating thereto; or (c) the expiration of all statutes of limitation applicable to possible Claims arising out of Indemnitee’s Status.

Section 7.6    Notice by Each Party. Indemnitee shall promptly notify the Partnership in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document or communication relating to any Proceeding or Claim for which Indemnitee may be entitled to indemnification or advancement of Expenses hereunder; provided, however, that any failure of Indemnitee to so notify the Partnership shall not adversely affect Indemnitee’s rights under this Agreement except to the extent the Partnership shall have been materially prejudiced as a direct result of such failure. The Partnership shall promptly notify Indemnitee in writing as to the pendency of any Proceeding or Claim that may involve a claim against Indemnitee for which Indemnitee may be entitled to indemnification or advancement of Expenses hereunder.

Section 7.7    Amendment. This Agreement may not be modified or amended except by a written instrument executed by or on behalf of each of the parties hereto.

Section 7.8    Waivers. The observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) by the party entitled to enforce such term only by a writing signed by the party against which such waiver is to be asserted. Unless otherwise expressly provided herein, no delay on the part of any party hereto in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any party hereto of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder.

Section 7.9    Entire Agreement. This Agreement and the documents expressly referred to herein constitute the entire agreement between the parties hereto with respect to the matters covered hereby, and any other prior or contemporaneous oral or written understandings or agreements with respect to the matters covered hereby, including without limitation any prior indemnification agreements, are expressly superseded by this Agreement.

Section 7.10    Severability. If any provision of this Agreement (including any provision within a single section, paragraph or sentence) or the application of such provision to any Person or circumstance, shall be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Agreement or affect the application of such provision to other Persons or circumstances, it being the intent and agreement of the parties that this Agreement shall be deemed amended by modifying such provision to the extent necessary to render it valid, legal and enforceable while preserving its intent, or if such modification is not possible, by substituting therefor another provision that is valid, legal and enforceable and that achieves the same objective. Any such finding of invalidity or unenforceability shall not prevent the enforcement of such provision in any other jurisdiction to the maximum extent permitted by applicable law.

Section 7.11    Notices. All notices and other communications hereunder shall be in writing and shall be deemed given upon (a) transmitter’s confirmation of a receipt of a facsimile transmission if during normal business hours of the recipient, otherwise on the next business day, (b) confirmed delivery of a standard overnight courier or when delivered by hand or (c) the expiration of five business days after the date mailed by certified or registered mail (return receipt requested), postage prepaid, to the parties at the following addresses (or at such other addresses for a party as shall be specified by like notice):

or to such other address or to such other individuals as any party shall have last designated by notice to the other parties. All notices and other communications given to any party in accordance with the provisions of this Agreement shall be deemed to have been given when delivered or sent to the intended recipient thereof in accordance with and as provided in the provisions of this Section 7.11.

Section 7.12    Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the State of Delaware without regard to the principles of conflict of laws.

Section 7.13    Certain Construction Rules.

(a)    The article and section headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. As used in this Agreement, unless otherwise provided to the contrary, (1) all references to days shall be deemed references to calendar days and (2) any reference to a “Section” or “Article” shall be deemed to refer to a section or article of this Agreement. The words “hereof,” “herein” and “hereunder” and words of similar import referring to this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” Unless otherwise specifically provided for herein, the term “or” shall not be deemed to be exclusive. Whenever the context may require, any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa.

(b)    For purposes of this Agreement, references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; references to “serving at the request of the General Partner” shall include any service as a director, officer, employee or agent of the General Partner or the Partnership which imposes duties on, or involves services by, such director, nominee, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner the person reasonably believed to be in the interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interest of the Partnership” for purposes of this Agreement and the DRULPA.

(c)    In the event of a merger, consolidation or amalgamation of the Company with or into any other entity, references to the “Partnership” shall include the entity surviving or resulting from the merger, consolidation or amalgamation as well as the Partnership, and Indemnitee shall stand in the same position under this Agreement with respect to the surviving or resulting entity as Indemnitee would stand with respect to the Partnership if its existence had continued upon and after the merger, consolidation or amalgamation.

Section 7.14    Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument, notwithstanding that both parties are not signatories to the original or same counterpart.

Section 7.15    Certain Persons Not Entitled to Indemnification. The Partnership shall not be obligated pursuant to the terms of this Agreement:

(a)    To indemnify Indemnitee if (and to the extent that) a final decision by a court or arbitration body having jurisdiction in the matter shall ultimately determine that such indemnification is not permitted by the Partnership Agreement; or

(b)    To indemnify Indemnitee for the payment to the Partnership of profits pursuant to Section 16(b) of the Exchange Act, or Expenses incurred by Indemnitee for Proceedings in connection with such payment under Section 16(b) of the Exchange Act.

Section 7.16    Indemnification for Negligence, Gross Negligence, etc. Without limiting the generality of any other provision hereunder, it is the express intent of this Agreement that Indemnitee be indemnified and Expenses be advanced regardless of Indemnitee’s acts of negligence or gross negligence to the extent that indemnification and advancement of Expenses is allowed pursuant to the terms of this Agreement and under the Partnership Agreement.

Section 7.17    Mutual Acknowledgments. Both the Partnership and Indemnitee acknowledge that in certain instances, applicable law (including applicable federal law that may preempt or override applicable state law) or public policy may prohibit the Partnership from indemnifying the directors, officers, employees, agents or fiduciaries of the General Partner under this Agreement or otherwise. For example, the Partnership and Indemnitee acknowledge that the U.S. Securities and Exchange Commission has taken the position that indemnification of directors, officers and controlling Persons of the Partnership for liabilities arising under federal securities laws is against public policy and, therefore, unenforceable. Indemnitee understands and acknowledges that the Partnership has undertaken or may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Partnership’s right under public policy to indemnify Indemnitee. In addition, the Partnership and Indemnitee acknowledge that federal law prohibits indemnifications for certain violations of the Employee Retirement Income Security Act of 1974, as amended.

Section 7.18    Enforcement. The Partnership agrees that its execution of this Agreement shall constitute a stipulation by which it shall be irrevocably bound in any court or arbitration in which a proceeding by Indemnitee for enforcement of Indemnitee’s rights hereunder shall have been commenced, continued or appealed, that its obligations set forth in this Agreement are unique and special, and that failure of the Partnership to comply with the provisions of this Agreement will cause irreparable and irremediable injury to Indemnitee, for which a remedy at law will be inadequate. As a result, in addition to any other right or remedy Indemnitee may have at law or in equity with respect to breach of this Agreement, Indemnitee shall be entitled to injunctive or mandatory relief directing specific performance by the Partnership of its obligations under this Agreement. The Partnership agrees not to seek, and agrees to waive any requirement for the securing or posting of, a bond in connection with Indemnitee’s seeking or obtaining such relief.

Section 7.19    Successors and Assigns. All of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and their respective successors, assigns, heirs, executors, administrators, legal representatives.

Section 7.20    Period of Limitations. No legal action shall be brought and no cause of action shall be asserted by or on behalf of the Partnership or any affiliate of the Partnership against Indemnitee or Indemnitee’s spouse, heirs, executors, or personal or legal representatives after the expiration of one year from the date of accrual of that cause of action, and any claim or cause of action of the Partnership or its affiliate shall be extinguished and deemed released unless asserted by the timely filing of a legal action within that one-year period; provided, however, that for any claim based on Indemnitee’s breach of fiduciary duties to the Partnership or its unitholders, the period set forth in the preceding sentence shall be three years instead of one year; and provided, further, that, if any shorter period of limitations is otherwise applicable to any such cause of action, the shorter period shall govern.

IN WITNESS WHEREOF, this Agreement has been duly executed and delivered to be effective as of the date first above written.

The Partnership entered into an Indemnification Agreement with each of Alan L. Gosule, Royce W. Mitchell and Arthur L. Smith that is otherwise identical to the one entered into with Phillip A. Gobe.
