party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.  An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

9.                                      The respective indemnities, agreements, representations, warranties and other statements of the Partnership and the Investor, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Investor or any controlling person of the Investor, or the Partnership, or any officer or director of the General Partner or controlling person of the Partnership, and shall survive delivery of and payment for the Investor Units.

10.                               If for any reason other than a breach of the Investor of any of its representations, warranties and covenants hereunder, any Investor Units are not delivered by or on behalf of the Partnership as provided herein, the Partnership will reimburse the Investor for all out-of-pocket expenses of the Investor, including fees and disbursements of counsel, reasonably incurred by the Investor in making preparations for the purchase, sale and delivery of the Investor Units not so delivered, but the Partnership shall then be under no further liability to the Investor except as provided in Section 8 hereof.

11.                               All statements, requests, notices and agreements hereunder shall be in writing, and if to the Investor shall be delivered or sent by mail, telex or facsimile transmission to SN UR Holdings, LLC at 1000 Main Street, Suite 300, Houston, Texas 77002 Attention: President, facsimile number (713) 756-2784; and if to the Partnership shall be delivered or sent by mail, telex or facsimile transmission to Sanchez Production Partners LP at 1000 Main Street, Suite 300, Houston, Texas 77002, Attention: Chief Financial Officer, facsimile number (832) 742-3823.  Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

12.                               This Agreement shall be binding upon, and inure solely to the benefit of, the Investor, the Partnership and, to the extent provided in Section 8 hereof, the officers and directors of the General Partner and each person who controls the Partnership or the Investor, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue

20

of this Agreement.  No purchaser of any of the Investor Units from the Investor shall be deemed a successor or assign by reason merely of such purchase.

13.                               Time shall be of the essence of this Agreement.  As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

14.                               This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Partnership and the Investor, or any of them, with respect to the subject matter hereof.

15.                               THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF TEXAS.  The Partnership and the Investor agree that any suit or proceeding arising in respect of this agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of Texas or, if that court does not have subject matter jurisdiction, in any state court located in The City of Houston, Harris County and the Partnership and the Investor agree to submit to the jurisdiction of, and to venue in, such courts.

16.                               The Partnership and the Investor hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

If the foregoing is in accordance with the Investor’s understanding, please sign and return to us counterparts hereof, and upon the acceptance hereof by the Investor, this letter and such acceptance hereof shall constitute a binding agreement between the Investor and the Partnership.
