Article II
BUSINESS OPPORTUNITIES

     2.1 Fund Business Opportunities. For a period ending on the earlier of (a) the fifth anniversary of the Closing Date and (b) a Change of Control of the MLP or the General Partner, if any Fund Entity is presented with an opportunity to pursue, purchase or invest in any Fund Business Opportunity, such Fund Entity shall give prompt written notice of such Fund Business Opportunity to the General Partner on behalf of the MLP Group. Such notice shall set forth all information available to the Fund Group, including, but not limited to, the identity of the Fund Business Opportunity and its seller, the proposed price, all written information about the Fund Business Opportunity provided to the Fund Group by or on behalf of the seller or marketer of same, as well as any information or analyses compiled by the Fund Group from other sources (such information referred to collectively herein as “Fund Business Opportunity Information”), and shall include an offer from such Fund Entity to the MLP for the MLP to acquire or invest in up to twenty-five percent (25%) (or such greater percentage as shall be specified in the notice solely in the discretion of such Fund Entity) of the Fund Business Opportunity. Such Fund Entity shall continue to provide promptly to the General Partner, on behalf of the MLP Group, any and all Fund Business Opportunity Information subsequently received or generated. Such Fund Entity shall use its reasonable efforts to provide for the disclosure of the Fund Business Opportunities Information to the MLP Group under the terms and conditions of any confidentiality agreement covering such information, and the Parties shall maintain the confidentiality of all such Fund Business Opportunity Information, subject to compliance with applicable law. As soon as practicable, but in all cases within thirty (30) days after receipt of such initial notification and information, the General Partner, on behalf of the MLP Group, shall notify such Fund Entity that either (a) the General Partner, on behalf of the MLP Group, has elected to cause a member of the MLP Group to pursue the opportunity to acquire or invest in up to twenty-five percent (25%) (or, at the election of the MLP, a larger interest if the notice included an offer to the MLP of an interest exceeding twenty-five percent (25%) such greater percentage as shall be specified in the notice) of the Fund Business Opportunity alongside the Fund Group or (b) the General Partner, on behalf of the MLP Group, has elected not to cause a member of the MLP Group to pursue the opportunity to acquire or invest in the Fund Business Opportunity. If the General Partner fails to notify such Fund Entity of its decision within thirty (30) days after receipt of such initial notification and information, the General Partner will be deemed to have, on behalf of the MLP Group, elected not to cause a member of the MLP Group to pursue the opportunity to acquire or invest in the Fund Business Opportunity. If the General Partner, on behalf of the MLP Group, elects not to cause a member of the MLP Group to pursue any such opportunity or is deemed to do so pursuant to this Section 2.1, or at any time after electing to pursue such opportunity the General Partner, on behalf of the MLP Group, abandons such opportunity (as evidenced in writing by the General Partner following the request of such Fund Entity), the Fund Group may pursue such opportunity without the participation of the MLP Group; provided, however, that such opportunity (x) is consummated within 180 days after the General Partner’s receipt of the initial notification and information, and (y) as consummated, is on terms not materially more favorable to the Fund Group than the terms proposed in the initial notification and information. If any such opportunity is not so consummated during such period, then no Fund Entity may consummate such opportunity without complying again in full with the provisions of this Section 2.1.

     2.2 Scope of Prohibition. Except as provided in this Article II, the Parties and their Affiliates shall be free to engage in any business activity whatsoever without the participation of the other, including, without limitation, those that may be in direct competition with the MLP Group or the Fund Group, as the case may be.

     2.3 Enforcement.

          (a) The Parties agree and acknowledge that there is no adequate remedy at law for the breach by the Parties of the covenants and agreements set forth in this Article II, and that any breach by the Parties of the covenants and agreements set forth in Article II would result in irreparable injury. The Parties further agree and acknowledge that any Party to this Agreement may, in addition to the other remedies that may be available hereunder or under applicable law, file a suit in equity to enjoin the violating Party from such breach, and the Parties consent to the issuance of injunctive relief hereunder.

          (b) If any court determines that any provision of this Article II is invalid or unenforceable, the remainder of such provisions shall not thereby be affected and shall be given full effect without regard to the invalid provision. If any court construes any provision of this Article II, or any part thereof, to be unreasonable because of the duration of such provision or the geographic scope thereof, such court shall have the power to reduce the duration or restrict the geographic scope of such provision and to enforce such provision as so reduced or restricted.

     2.4 New Funds; Application to QEP Funds. If the Fund General Partner or any of its Affiliates shall close any new investment fund whose principal investment purpose and scope is to acquire cash-flow producing, mature, onshore oil and natural gas properties in North America (a “New Fund”) within two years of the Closing Date, then such New Fund shall enter into an amendment to this Agreement (a “New Fund Amendment”) providing that the provisions of this Agreement, but not this Section 2.4, shall apply to such New Fund to the same extent as any Fund Entity. For purposes hereof, the close on a New Fund will occur on the date that the New Fund closes on at least the minimum required investment from investors as specified in the offering materials for the New Fund. For the avoidance of doubt, the provisions of this Agreement, including this Section 2.4 shall not apply to any QEP Fund.

Article III
RIGHT OF FIRST OFFER

     3.1 Right of First Offer; Procedures. For a period ending on the earlier of (a) the fifth anniversary of the Closing Date and (b) a Change of Control of the MLP or the General Partner, if any Fund Entity (the “Disposing Party”) desires to sell or otherwise Transfer any Fund Subject Assets, the Disposing Party shall provide the MLP Group a right of first offer to acquire such Fund Subject Assets (the “Fund Sale Assets”) pursuant to the following procedures:

          (a) The Disposing Party shall deliver a written notice (the “Disposing Party Notice”) to the General Partner, on behalf of the MLP Group, that shall describe in reasonable detail the Fund Sale Assets. Except as expressly provided in the Disposing Party Notice, the

Disposing Party Notice shall not constitute an offer to sell the Fund Sale Assets to the MLP Group.

          (b) The General Partner, on behalf of the MLP Group and with the approval of the Conflicts Committee, shall have a period of thirty days or such longer time as agreed by the Conflicts Committee and the Disposing Party (the “Negotiation Period”) from the date of the General Partner’s receipt of the Disposing Party Notice to provide to the Disposing Party the MLP Group’s offer to purchase the Fund Sale Assets on terms approved by the Conflicts Committee.

          (c) If the Disposing Party and the General Partner, on behalf of the MLP Group and with the approval of the Conflicts Committee, agree upon the terms of sale for the Fund Sale Assets prior to the expiration of the Negotiation Period (as same may be extended with the approval of the Disposing Party), such Parties shall enter into definitive documentation to effect such Transfer, which shall be closed within thirty (30) days after the end of the Negotiation Period or such longer period as may be reasonably necessary to complete a unitholder vote by the MLP (if required), to finance the purchase of the Fund Sale Assets (if required), including by means of the issuance of additional Common Units or debt securities, or to obtain any required governmental or other third party consents or approvals.

          (d) If, at the end of the Negotiation Period, the Disposing Party and the General Partner, on behalf of the MLP Group and with the approval of the Conflicts Committee, each acting in good faith, have not agreed upon the terms of sale for the Fund Sale Assets, or if the Transfer is not completed within the period specified in Section 3.1(c), then the Disposing Party may thereafter Transfer the Fund Sale Assets to a third party without further restriction except that, if the Disposing Party elects to consider bids from third parties for the Fund Sale Assets in a formal process, the MLP Group will be permitted to participate in such process, provided that nothing in this Section 3.1(d) will preclude the Disposing Party from dealing solely with independent purchasers outside of any such formal process.

Article IV
PAYMENT; INDEMNIFICATION

     4.1 Title, Tax and Environmental Indemnifications.

          (a) Subject to the provisions of Section 4.2 and Section 4.3, each Fund Entity, severally, in proportion to its respective Property Contributor Percentage, agrees to indemnify, defend and hold harmless the MLP Group from and against:

or (B) are intended to be used by the MLP Group from and after the Closing Date as described in the Registration Statement;

               (ii) any Losses suffered or incurred by the MLP Group by reason of or arising out of any federal, state and local income tax liabilities attributable to the ownership or operation of the MLP Assets prior to the Closing Date, including (A) any such income tax liabilities that may result from the consummation of the formation transactions for the MLP Group occurring on or prior to the Closing Date and (B) any income tax liabilities arising under Treasury Regulation Section 1.1502-6 and any similar provision from state, local or foreign applicable law, by contract, as successor, transferred or otherwise and which income tax is attributable to having been a member of any consolidated, combined or unitary group prior to the Closing Date; and

               (iii) any Covered Environmental Losses suffered or incurred by the MLP Group.

     4.2 Limitations Regarding Indemnification.

          (a) The indemnification obligations of the Fund Group set forth in Section 4.1 shall survive until the first anniversary of the Closing Date in the case of subsections (a)(i) and (a)(iii), and until sixty (60) days after the expiration of any applicable statute of limitations in the case of subsection (a)(ii); provided, however, that any such indemnification obligation shall remain in full force and effect thereafter only with respect to any bona fide claim made thereunder prior to any such expiration and then only for such period as may be necessary for the resolution thereof.

          (b) No claims may be made against the Fund Group for indemnification pursuant to Section 4.1(a)(i) or Section 4.1(a)(iii) unless the aggregate dollar amount of the Material Losses suffered or incurred by the MLP Group exceeds $4,000,000; after such time each Fund Entity shall be liable, severally, in proportion to its respective Property Contributor Percentage, to the extent and only to the extent that such claims exceed $4,000,000. The term “Material Losses” means only those Losses described in Section 4.1(a)(i) or Section 4.1(a)(iii) that exceed seventy-five thousand dollars ($75,000).

     4.3 Indemnification Procedures.

          (a) Each Party seeking indemnification (each, an “Indemnified Party”) pursuant to this Article IV agrees that within a reasonable period of time after it shall become aware of facts giving rise to a claim for indemnification pursuant to this Article IV, it will provide notice thereof in writing to the Parties from whom indemnification is sought pursuant to this Article IV (each, an “Indemnifying Party”) specifying the nature of and specific basis for such claim; provided, however, that no Indemnified Party shall submit claims more frequently than once a calendar quarter (or twice in the case of the last calendar quarter prior to the expiration of the applicable indemnity coverage under this Agreement); provided further, that failure to timely provide such notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is materially prejudiced by such delay or omission.

          (b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification set forth in this Article IV, including, without limitation, the selection of counsel (provided that such counsel shall be reasonably acceptable to the Indemnified Parties), determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent (which consent shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Parties unless it includes a full release of the Indemnified Parties and their respective Subsidiaries from such matter or issues, as the case may be.

          (c) The Indemnified Parties agree to cooperate fully with the Indemnifying Parties with respect to all aspects of the defense of any claims covered by the indemnification set forth in Article IV, including, without limitation, the prompt furnishing to the Indemnifying Parties of any correspondence or other notice relating thereto that the Indemnified Parties may receive, permitting the names of the Indemnified Parties to be utilized in connection with such defense, the making available to the Indemnifying Parties of any files, records or other information of the Indemnified Parties that Indemnifying Parties consider relevant to such defense and the making available to Indemnifying Parties of any employees of the Indemnified Parties; provided, however, that in connection therewith Indemnifying Parties agree to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Parties and further agrees to reasonably maintain the confidentiality of all files, records and other information furnished by the Indemnified Parties pursuant to this Section 4.3. In no event shall the obligation of the Indemnified Parties to cooperate with Indemnifying Parties as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Parties 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 IV; provided, however, that the Indemnified Parties may, at their option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Parties agree to keep any such counsel hired by the Indemnified Parties reasonably informed as to the status of any such defense, but Indemnifying Parties shall have the right to retain sole control over such defense.

          (d) In determining the amount of any Losses for which the Indemnified Parties are entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Parties, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Parties as a result of such claim and (ii) all amounts recovered by the Indemnified Parties under contractual indemnities from third parties. The Indemnified Parties hereby agree to use commercially reasonable efforts to realize any applicable insurance proceeds or amounts recoverable under such contractual indemnities; provided, however, that the costs and expenses (including, without limitation, court costs and reasonable attorneys’ fees) of the Indemnified Parties in connection with such efforts shall be promptly reimbursed by the Indemnifying Parties. To the extent that Indemnifying Parties have made any indemnification payment hereunder in respect of a claim for which the Indemnified Parties have asserted a related claim for insurance proceeds or under a contractual indemnity, Indemnifying Parties shall be subrogated to the rights of the Indemnified Parties to receive the proceeds of such insurance or contractual indemnity.

     5.3 Entire Agreement. This Agreement constitutes the entire agreement of the Parties relating to the matters contained herein, superseding all prior contracts or agreements, whether oral or written, relating to the matters contained herein.

     5.4 Jointly Drafted. This Agreement, and all the provisions of this Agreement, shall be deemed drafted by all of the Parties, and shall not be construed against any Party on the basis of that Party’s role in drafting this Agreement.

     5.5 Effect of Waiver or Consent. No waiver or consent, express or implied, by any Party of or to any breach or default by any Person in the performance by such Person of its obligations hereunder shall be deemed or construed to be a consent or waiver of or to any other breach or default in the performance by such Person of the same or any other obligations of such Person hereunder. Failure on the part of a Party to complain of any act of any Person or to declare any Person in default, irrespective of how long such failure continues, shall not constitute

a waiver by such Party of its rights hereunder until the applicable statute of limitations period has run.

     5.6 Amendment or Modification. This Agreement may be amended or modified only (a) pursuant to Section 2.4 or (b) from time to time by the written agreement of the Parties; provided, however, that the MLP may not, without the prior approval of the Conflicts Committee, agree to any amendment or modification of this Agreement that, in the reasonable discretion of the General Partner (i) would have a material adverse effect on the holders of Common Units or (ii) materially limit or impair the rights or reduce the obligations of the Parties under this Agreement. Each such instrument shall be reduced to writing and shall be designated on its face an “Amendment” or an “Addendum” to this Agreement.

     5.7 Assignment; No Third-Party Beneficiaries. None of the Parties shall have the right to assign its rights or obligations under this Agreement without the prior written consent of all other Parties. The provisions of this Agreement are enforceable solely by the Parties (including any permitted assignee), but no limited partner or member of any Fund Entity, Holdco, the Fund General Partner or the MLP or other Person shall have the right, separate and apart from the Parties hereto, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.

     5.8 Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signatory Parties had signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument.

     5.9 Severability. If any provision of this Agreement or the application thereof to any Person or circumstance shall be held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

     5.10 Further Assurances. In connection with this Agreement and all transactions contemplated by this Agreement, each Party agrees to execute and deliver such additional documents and instruments and to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of this Agreement and all such transactions.
