Sanchez Production Partners LP, a Delaware limited partnership (the “Partnership”), confirms its agreement (this “Agreement”) with FBR Capital Markets & Co. (“FBR”) as follows:

Sanchez Production Partners GP LLC, a Delaware limited liability company, is the sole general partner of the Partnership (the “General Partner”).

1. Issuance and Sale of Securities. The Partnership agrees that, from time to time during the term of this Agreement, on the terms and subject to the conditions set forth herein, it may issue and sell through FBR, acting as sales agent, common units representing limited partner interests in the Partnership (the “Common Units”). The Common Units to be issued and sold pursuant to this Agreement are referred to herein as the “Securities.” Notwithstanding anything to the contrary contained herein, the parties hereto agree that compliance with the limitations set forth in this Section 1 regarding the number and aggregate sale price of the Securities shall be the sole responsibility of the Partnership, and that FBR shall have no obligation in connection with such compliance. The issuance and sale of the Securities through FBR will be effected pursuant to the Registration Statement (as defined below) filed by the Partnership and declared effective by the Securities and Exchange Commission (the “Commission”), although nothing in this Agreement shall be construed as requiring the Partnership to use the Registration Statement to issue any Securities.

The Partnership has filed, in accordance with the provisions of the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder (the “Securities Act Regulations”), with the Commission, a registration statement on Form S-3 (File No. 333-202575), including a base prospectus, relating to certain securities, including the Securities to be issued from time to time by the Partnership, and which incorporates by reference documents that the Partnership has filed or will file in accordance with the provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations thereunder (collectively, the “Exchange Act Regulations”). The Partnership will prepare one or more prospectus supplements specifically relating to the Securities (each a “Prospectus Supplement”) to the base prospectus included as part of such registration statement. The Partnership will furnish to FBR, for use by FBR, copies of the base prospectus included as part of such registration statement, as supplemented by one or more Prospectus Supplements, relating to the Securities. Except where the context otherwise requires, such registration statement, as amended when it became effective,

including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part of such registration statement pursuant to Rule 430B of the Securities Act, is herein called the “Registration Statement.” The base prospectus, including all documents incorporated or deemed incorporated therein by reference to the extent such information has not been superseded or modified in accordance with Rule 412 under the Securities Act (as qualified by Rule 430B(g) of the Securities Act), included in the Registration Statement, as it may be supplemented by one or more Prospectus Supplements, in the form in which such base prospectus and/or a Prospectus Supplement have most recently been filed by the Partnership with the Commission pursuant to Rule 424(b) under the Securities Act, is herein called the “Prospectus.” Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated or deemed incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein (the “Incorporated Documents”).

For purposes of this Agreement, all references to the Registration Statement, the Prospectus or to any amendment or supplement thereto shall be deemed to include the most recent copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval System, or if applicable, the Interactive Data Electronic Application system when used by the Commission (collectively, “EDGAR”).

2. Placements. Each time that the Partnership wishes to issue and sell the Securities hereunder (each, a “Placement”), it will notify FBR by email notice (or other method mutually agreed to in writing by the parties) containing the parameters in accordance with which it desires the Securities to be sold, which shall at a minimum include the number of Securities to be issued (the “Placement Securities”), the time period during which sales are requested to be made, any limitation on the number of Placement Securities that may be sold in any one day and any minimum price below which sales may not be made (a “Placement Notice”), a form of which is attached hereto as Schedule 1. Each Placement Notice shall originate from any of the individuals from the Partnership set forth on Schedule 3 (with a copy to each of the other individuals from the Partnership listed on such schedule), and shall be addressed to each of the individuals from FBR set forth on Schedule 3, as such schedule may be amended from time to time. If FBR wishes to accept such proposed terms included in a Placement Notice (which it may decline to do so for any reason in its sole discretion) it may do so by providing email notice (or other method mutually agreed to in writing by the parties) to the individuals from the Partnership set forth on Schedule 3. Each Placement Notice shall be effective upon receipt by the Partnership of FBR’s acceptance of the terms of the Placement Notice unless and until (i) the entire amount of the Placement Securities thereunder has been sold, (ii) the Partnership suspends or terminates the Placement Notice, (iii) the Partnership issues a subsequent Placement Notice with parameters superseding those on the earlier dated Placement Notice or (iv) this Agreement has been terminated under the provisions of Section 13. The amount of any discount, commission or other compensation to be paid by the Partnership to FBR in connection with the sale of the Placement Securities shall be calculated in accordance with the terms set

forth in Schedule 2. It is expressly acknowledged and agreed that neither the Partnership nor FBR will have any obligation whatsoever with respect to a Placement or any Placement Securities unless and until the Partnership delivers a Placement Notice to FBR and FBR accepts such Placement Notice pursuant to the terms set forth above, and then only upon the terms specified therein and herein. In the event of a conflict between the terms of Sections 2 or 3 of this Agreement and the terms of a Placement Notice, the terms of the Placement Notice will control.

3. Sale of Placement Securities by FBR. Subject to the terms and conditions of this Agreement, for the period specified in a Placement Notice, FBR will use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the NYSE MKT LLC (the “Exchange”), to sell the Placement Securities up to the amount specified in, and otherwise in accordance with the terms of, such Placement Notice. FBR will provide written confirmation to the Partnership no later than the opening of the Trading Day (as defined below) immediately following the Trading Day on which it has made sales of Placement Securities hereunder setting forth the number of Placement Securities sold on such day, the compensation payable by the Partnership to FBR pursuant to Section 2 with respect to such sales, and the Net Proceeds (as defined below) payable to the Partnership, with an itemization of the deductions made by FBR (as set forth in Section 5(b)) from the gross proceeds that it receives from such sales. Subject to the terms of a Placement Notice, FBR hereby covenants and agrees not to sell Placement Securities other than (i) by any method permitted by law deemed to be an “at-the-market” offering as defined in Rule 415 of the Securities Act, including without limitation sales made directly on the Exchange, on any other existing trading market for the Common Units or to or through a market maker, or (ii) by any other method permitted by law, including but not limited to negotiated transactions. For the purposes hereof, “Trading Day” means any day on which the Common Units are purchased and sold on the Exchange.

4. Suspension of Sales. The Partnership or FBR may, upon notice to the other party in writing (including by email correspondence to each of the individuals of the other party set forth on Schedule 3, if receipt of such correspondence is actually acknowledged by any of the individuals to whom the notice is sent, other than via auto-reply) or by telephone (confirmed immediately by verifiable facsimile transmission or email correspondence to each of the individuals of the other party set forth on Schedule 3), suspend any sale of Placement Securities; provided, however, that such suspension shall not affect or impair any party’s obligations with respect to any Placement Securities sold hereunder prior to the receipt of such notice. Each of the parties agrees that no such notice under this Section 4 shall be effective against any other party unless it is made to one of the individuals named on Schedule 3 hereto, as such Schedule may be amended from time to time.

a. Sale of Placement Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, upon FBR’s acceptance of the terms of a Placement Notice, and unless the sale of the Placement Securities described therein has been declined, suspended, or otherwise

terminated in accordance with the terms of this Agreement, FBR, for the period specified in the Placement Notice, will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Placement Securities up to the amount specified in, and otherwise in accordance with the terms of, such Placement Notice. The Partnership acknowledges and agrees that (i) there can be no assurance that FBR will be successful in selling Placement Securities, (ii) FBR will incur no liability or obligation to the Partnership or any other person or entity if it does not sell Placement Securities for any reason other than a failure by FBR to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Placement Securities as required under this Agreement and (iii) FBR shall be under no obligation to purchase Placement Securities on a principal basis pursuant to this Agreement, except as otherwise agreed to in writing by FBR and the Partnership, which such writing shall include a price agreed to at the time of sale of any Placement Securities on a principal basis.

b. Settlement of Placement Securities. Unless otherwise specified in the applicable Placement Notice, settlement for sales of Placement Securities will occur on the third (3^rd) Trading Day (or such earlier day as is industry practice for regular-way trading) following the date on which such sales are made (each, a “Settlement Date”). The amount of proceeds to be delivered to the Partnership on a Settlement Date against receipt of the Placement Securities sold (the “Net Proceeds”) will be equal to the aggregate sales price received by FBR, after deduction for (i) FBR’s commission, discount or other compensation for such sales payable by the Partnership pursuant to Section 2 hereof, and (ii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales.

c. Delivery of Placement Securities. On or before each Settlement Date, the Partnership will, or will cause its transfer agent to, electronically transfer the Placement Securities being sold by crediting FBR’s or its designee’s account (provided FBR shall have given the Partnership written notice of such designee at least one Trading Day prior to the Settlement Date) at The Depository Trust Company (“DTC”) through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto which in all cases shall be freely tradable, transferable and registered units eligible for delivery through DTC. On each Settlement Date, FBR will deliver the related Net Proceeds in same day funds to an account designated by the Partnership on, or prior to, the Settlement Date. The Partnership agrees that if the Partnership, or its transfer agent (if applicable), defaults in its obligation to deliver Placement Securities on a Settlement Date, the Partnership agrees that in addition to and in no way limiting the rights and obligations set forth in Section 11(a) hereto, it will (i) hold FBR harmless against any loss, claim, damage, or reasonable, documented expense (including reasonable and documented legal fees and expenses), as incurred, arising out of or in connection with such default by the Partnership or its transfer agent (if applicable) and (ii) pay to FBR (without duplication) any commission, discount, or other compensation to which it would otherwise have been entitled absent such default.

d. Limitations on Offering Size. Under no circumstances shall the Partnership cause or request the offer or sale of any Securities, if after giving effect to

the sale of such Securities, the aggregate offering price of the Securities sold pursuant to this Agreement would exceed the lesser of (A) the amount available for offer and sale under the currently effective Registration Statement (including, if applicable, pursuant to Instruction I.B.6. of Form S-3), or (B) the amount authorized from time to time to be issued and sold under this Agreement by the board of directors of the General Partner (the “Board”), or a duly authorized committee thereof, and notified to FBR in writing. Under no circumstances shall the Partnership cause or request the offer or sale of any Securities pursuant to this Agreement at a price lower than the minimum price, if any, authorized from time to time by the Board or a duly authorized committee thereof, and notified to FBR in writing.

aa. Review of Environmental Laws. The Partnership has reviewed the effect of Environmental Laws in effect on the date hereof on the business, operations and properties of the Partnership and its subsidiaries, in the course of which it identified and evaluated associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with such Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties).

7. Covenants of the Partnership. The Partnership covenants and agrees with FBR that:

a. Registration Statement Amendments. After the filing of the first Prospectus Supplement relating to the Securities, and during any period in which a prospectus relating to any Placement Securities is required to be delivered by FBR under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act) (the “Prospectus Delivery Period”) (i) the Partnership will notify FBR promptly of the time when any subsequent amendment to the Registration Statement, other than documents incorporated by reference or amendments not related to any Placement, has been filed with the Commission and/or has become effective or any subsequent supplement to the Prospectus has been filed and of any request by the Commission for any amendment or supplement to the Registration Statement or Prospectus related to the Placement or for additional information related to the Placement, (ii) the Partnership will prepare and file with the Commission, promptly upon FBR’s request, any amendments or supplements to the Registration Statement or Prospectus that, in FBR’s reasonable opinion, may be necessary or advisable in connection with the distribution of the Placement Securities by FBR (provided, however, that the failure of FBR to make such request shall not relieve the Partnership of any obligation or liability hereunder, or affect FBR’s right to rely on the representations and warranties made by the Partnership in this Agreement; and provided, further, that the only remedy FBR shall have with respect to the failure to make such filing shall be to cease making sales under this Agreement until such amendment or supplement is filed); (iii) the Partnership will not file any amendment or supplement to the Registration Statement or Prospectus relating to the Placement Securities or a security convertible into the Placement Securities unless a copy thereof has been submitted to FBR within a reasonable period of time before the filing and FBR has not reasonably objected thereto (provided, however, that (A) the failure of FBR to make such objection shall not relieve the Partnership of any obligation or liability hereunder, or affect FBR’s right to rely on the representations and warranties made by the Partnership in this Agreement and (B) the Partnership have no obligation to provide FBR any advance copy of such filing or to provide FBR an opportunity to object to such filing if the filing does not name FBR or does not relate to the transaction herein provided; and provided, further, that the only remedy FBR shall have with respect to the failure by the Partnership to obtain such consent shall be to cease making sales under this Agreement), and the Partnership will furnish to FBR at the time of filing thereof a copy of any document that upon filing is deemed to be incorporated by reference into the Registration Statement or Prospectus, except for those documents available via EDGAR; and (iv) the Partnership will cause each amendment or supplement to the Prospectus to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Securities Act, or in the case of any document to be incorporated therein by reference, to be filed with the Commission as required pursuant to the Exchange Act, within the time period prescribed (the determination to file or not file any amendment or supplement with the Commission under this Section 7(a), based on the Partnership’s reasonable opinion or reasonable objections, shall be made solely by the Partnership).

b. Notice of Commission Stop Orders. The Partnership will advise FBR, promptly after it receives notice or obtains knowledge thereof, of the issuance or threatened issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of the suspension of the qualification of the Placement Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and it

will promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be issued. The Partnership will advise FBR promptly after it receives any request by the Commission for any amendments to the Registration Statement or any amendments or supplements to the Prospectus or any Issuer Free Writing Prospectus or for additional information related to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus.

c. Continued Compliance; Subsequent Changes. During the Prospectus Delivery Period, the Partnership will comply with all requirements imposed upon it by the Securities Act and the Securities Act Regulations, as from time to time in force, and will file on or before their respective due dates all reports and any definitive proxy or information statements required to be filed by the Partnership with the Commission pursuant to Sections 13(a), 13(c), 14, 15(d) or any other provision of or under the Exchange Act. If the Partnership has omitted any information from the Registration Statement pursuant to Rule 430A under the Securities Act, it will use its commercially reasonable efforts to comply with the provisions of and make all requisite filings with the Commission pursuant to said Rule 430A and to notify FBR promptly of all such filings. If during the Prospectus Delivery Period any event occurs as a result of which it is necessary, in the opinion of counsel for FBR or for the Partnership, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such Prospectus Delivery Period it is necessary, in the opinion of such counsel, to amend or supplement the Registration Statement or Prospectus in order to comply with the requirements of the Securities Act and the Securities Act Regulations, the Partnership will promptly notify FBR to suspend the offering of Placement Securities during such period and the Partnership will promptly amend or supplement the Registration Statement or Prospectus (at the expense of the Partnership) so as to correct such statement or omission or effect such compliance; provided, however, that the Partnership may delay the filing of any amendment or supplement, if in the judgment of the Partnership, it is in the best interest of the Partnership.

d. Listing; Blue Sky and Other Qualifications. During the Prospectus Delivery Period, the Partnership will use its commercially reasonable efforts to cause the Placement Securities to be listed on the Exchange and to qualify the Placement Securities for offering and sale, or to obtain an exemption for the Securities to be offered and sold, under the securities laws of such jurisdictions in the United States as FBR reasonably designates and to continue such qualifications in effect so long as required for the distribution of the Placement Securities; provided, however, that the Partnership shall not be obligated to file any general consent to service of process or to qualify as a foreign limited partnership or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

e. Delivery of Registration Statement and Prospectus. The Partnership will furnish to FBR and its counsel (at the reasonable expense of the Partnership) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein) and all amendments and supplements to the Registration Statement or Prospectus that are filed with the Commission during the Prospectus Delivery Period (including all documents filed with the Commission during such period that are deemed to be incorporated by reference therein), in

each case as soon as reasonably practicable and in such quantities as FBR may from time to time reasonably request and, at FBR’s request, will also furnish copies of the Prospectus to each exchange or market on which sales of the Placement Securities may be made; provided, however, that the Partnership shall not be required to furnish any document (other than the Prospectus) to FBR to the extent such document is available on EDGAR.

f. Earnings Statement. The Partnership will make generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Partnership’s current fiscal quarter, an earnings statement covering a 12-month period that satisfies the provisions of Section 11(a) and Rule 158 of the Securities Act.

g. Use of Proceeds. The Partnership will use the Net Proceeds received by it from the sale of the Securities as described in the Prospectus in the section entitled “Use of Proceeds.”

h. Notice of Other Sales. Without the prior written consent of FBR, the Partnership will not, directly or indirectly, offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Common Units (other than the Placement Securities offered pursuant to this Agreement) or securities convertible into or exchangeable for Common Units, warrants or any rights to purchase or acquire, Common Units during the period beginning on the date on which any Placement Notice is delivered to FBR hereunder and ending on the third (3rd) Trading Day immediately following the final Settlement Date with respect to Placement Securities sold pursuant to such Placement Notice (or, if the Placement Notice has been terminated or suspended prior to the sale of all Placement Securities covered by a Placement Notice, the date of such suspension or termination); and will not directly or indirectly in any other “at-the-market” or continuous equity transaction offer to sell, sell, contract to sell, grant any option to sell or otherwise dispose of any Common Units (other than the Placement Securities offered pursuant to this Agreement) or securities convertible into or exchangeable for Common Units, warrants or any rights to purchase or acquire, Common Units prior to the termination of this Agreement; provided, however, that the Partnership may (A) issue and sell Common Units pursuant to this Agreement; (B) file a registration statement on Form S-8 or issue and sell Common Units or securities convertible into or exchangeable for Common Units pursuant to any long-term incentive plan, employee unit option plan or unit ownership plan of the Partnership in effect at the Applicable Time; (C) issue or deliver Common Units issuable upon the conversion, vesting or exercise of securities (including long-term incentive plan awards, options and warrants) outstanding at the Applicable Time; and (D) issue and sell Common Units, or securities convertible into or exercisable for Common Units, offered and sold in a privately negotiated transaction to vendors, customers, strategic partners or potential strategic partners or other investors conducted in a manner so as not to be integrated with the offering of Common Units hereby. In the event that notice of a proposed sale is provided by the Partnership pursuant to this Section 7(h), FBR may (and shall if requested by the Partnership) suspend activity under this Agreement for such period of time as may be requested by the Partnership or as may be deemed appropriate by FBR.

i. Change of Circumstances. The Partnership will, at any time during the pendency of a Placement Notice, advise FBR promptly after it shall have received notice or obtained knowledge thereof, of any information or fact that would alter or affect in any material respect any opinion, certificate, letter or other document required to be provided to FBR pursuant to this Agreement.

j. Due Diligence Cooperation. During the term of this Agreement, the Partnership will cooperate with any reasonable due diligence review conducted by FBR or its representatives in connection with the transactions contemplated hereby, including, without limitation, providing information and making available documents and senior officers, during regular business hours and at the Partnership’s principal offices, as FBR may reasonably request.

k. Disclosure of Sales. After the filing of the first Prospectus Supplement relating to the Securities, the Partnership will disclose in its quarterly reports on Form 10-Q and in its annual report on Form 10-K the aggregate number of Securities sold through FBR pursuant to this Agreement, the Net Proceeds received by the Partnership with respect to all such sales pursuant to this Agreement, and the aggregate compensation payable by the Partnership to FBR with respect to all such sales pursuant to this Agreement.

l. Representation Dates; Certificate. Each time during the term of this Agreement that the Partnership:

i. amends or supplements (other than a prospectus supplement relating solely to an offering of securities other than the Placement Securities) the Registration Statement or the Prospectus relating to the Placement Securities, by means of a post-effective amendment, sticker, or supplement, but not by means of incorporation of documents by reference into the Registration Statement or the Prospectus relating to the Placement Securities;

ii. files an annual report on Form 10-K under the Exchange Act (including any Form 10-K/A containing amended financial information or a material amendment to the previously filed Form 10-K);

(Each date of filing of one or more of the documents referred to in clauses (i) through (iv) shall be a “Representation Date.”)

the Partnership shall furnish FBR (but in the case of clause (iv) above only if FBR reasonably requests) with a certificate, in the form attached hereto as Exhibit A within five (5) Trading Days of any Representation Date, provided, however, in the case of clause (i) above, the Partnership shall furnish FBR with a certificate, in the form attached hereto as Exhibit A on or prior to the date of the filing of the first Prospectus Supplement relating to the Securities. The requirement to provide a certificate under this Section 7(1) shall be deemed waived by FBR for any Representation Date occurring at a time at which no Placement Notice is pending, which waiver shall continue until the earlier to occur of the date the Partnership delivers a Placement Notice

hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date on which the Partnership files its annual report on Form 10-K. Notwithstanding the foregoing, (i) upon the delivery of the first Placement Notice hereunder and (ii) if the Partnership subsequently decides to sell Placement Securities following a Representation Date when the Partnership relied on such waiver and did not provide FBR with a certificate under this Section 7(1), then before FBR sells any Placement Securities, the Partnership shall provide FBR with a certificate, in the form attached hereto as Exhibit A, dated the date of the Placement Notice.

p. Market Activities.

a. Indemnification by the Partnership. The Partnership agrees to indemnify and hold harmless FBR, its partners, members, directors, officers, employees and agents and each person, if any, who controls FBR within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

i. against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

ii. against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 11(d) below) any such settlement is effected with the written consent of the Partnership, which consent shall not unreasonably be delayed or withheld; and

iii. against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made solely in reliance upon and in conformity with written information furnished to the Partnership by FBR expressly for use in the Registration Statement (or any amendment thereto), or in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto).

b. Indemnification by FBR. FBR agrees to indemnify and hold harmless the Partnership and each director and officer of the General Partner who signed the Registration Statement, and each person, if any, who (i) controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act or (ii) is controlled by or is under common control with the Partnership against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 11(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information relating to FBR and furnished to the Partnership in writing by FBR expressly for use therein.

c. Procedure. Any party that proposes to assert the right to be indemnified under this Section 11 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 11, notify as promptly as reasonably practicable each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but failure to so notify such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this Section 11 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 11 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly after the indemnifying party receives a written invoice relating to fees, disbursements and other charges in reasonable detail. An indemnifying party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 11 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (1) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (2) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

d. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 11 is applicable in accordance with its terms but is for any reason unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, liabilities, expenses and damages referred to therein, then each indemnifying party shall contribute to the total amount of such losses, claims, liabilities, expenses and damages incurred by such indemnified party as incurred (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the indemnified party from persons other than any indemnified party, who also may be liable for contribution) (A) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership on the one hand and FBR on the other hand from the offering of the Securities pursuant to this Agreement or (B) if the allocation provided by clause (A) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (A) above but also the relative fault of the Partnership on the one hand and of FBR on the other hand in connection with the statements or omissions that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership or FBR, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Partnership and FBR agree that it would not be just and equitable if contributions pursuant to this Section 11(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section 11(d) shall be deemed to include, for the purpose of this Section 11(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with Section 11(c) hereof.

Notwithstanding the foregoing provisions of this Section 11(d), FBR shall not be required to contribute any amount in excess of the commissions received by it under this Agreement and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 11(d), any person who controls a party to this Agreement within the meaning of the Securities Act or the Exchange Act, and any officers, directors, partners, employees or agents of FBR, will have the same rights to contribution as that party, and each officer and director of the General Partner who signed the Registration Statement will have the same rights to contribution as the Partnership, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 11(d), will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 11(d) except to the extent that the

failure to so notify such other party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section 11(c) hereof, no party will be liable for contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section 11(c) hereof.

12. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in Section 11 of this Agreement and all representations and warranties of the Partnership herein or in certificates delivered pursuant hereto shall survive, as of their respective dates, regardless of (i) any investigation made by or on behalf of FBR, any controlling persons, or the Partnership (or any of the General Partner’s officers, directors or controlling persons), (ii) delivery and acceptance of the Placement Securities and payment therefor or (iii) any termination of this Agreement.

a. Termination; General. FBR may terminate this Agreement, by notice to the Partnership, as hereinafter specified at any time (A) if there has been, since the time of execution of this Agreement or since the date as of which information is given in the Prospectus, any Material Adverse Effect, or any development that is reasonably likely to have a Material Adverse Effect or, in the sole judgment of FBR, is material and adverse and makes it impractical or inadvisable to market the Placement Securities or to enforce contracts for the sale of the Placement Securities, (B) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of FBR, impracticable or inadvisable to market the Placement Securities or to enforce contracts for the sale of the Placement Securities, (C) if trading in the Common Units has been suspended or limited by the Commission or the Exchange, or if trading generally on the Exchange has been suspended or limited, or minimum prices for trading have been fixed on the Exchange, (D) if any suspension of trading of any securities of the Partnership on any exchange or in the over-the-counter market shall have occurred and be continuing, (E) if a major disruption of securities settlements or clearance services in the United States shall have occurred and be continuing, or (F) if a banking moratorium has been declared by either U.S. Federal or New York authorities. Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination. If FBR elects to terminate this Agreement as provided in this Section 13(a), FBR shall provide the required notice as specified in Section 14 (Notices).

b. Termination by the Partnership. The Partnership shall have the right, by giving five (5) days notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and

Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination.

c. Termination by FBR. FBR shall have the right, by giving five (5) days notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination.

d. Automatic Termination. Unless earlier terminated pursuant to this Section 13, this Agreement shall automatically terminate upon the issuance and sale of all of the Placement Securities through FBR on the terms and subject to the conditions set forth herein except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination.

e. Continued Force and Effect. This Agreement shall remain in full force and effect unless terminated pursuant to Section 13(a), (b), (c), or (d) above or otherwise by mutual agreement of the parties; provided, however, that any such termination by mutual agreement shall in all cases be deemed to provide that Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) shall remain in full force and effect. Upon termination of this Agreement, the Partnership shall not have any liability to FBR for any discount, commission or other compensation with respect to any Placement Securities not otherwise sold by FBR under this Agreement.

f. Effectiveness of Termination. Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided, however, that such termination shall not be effective until the close of business on the date of receipt of such notice by FBR or the Partnership, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Placement Securities, such Placement Securities shall settle in accordance with the provisions of this Agreement.

Any party receiving Electronic Notice may request and shall be entitled to receive the notice on paper, in a nonelectronic form (“Nonelectronic Notice”) which shall be sent to the requesting party within ten (10) days of receipt of the written request for Nonelectronic Notice.

Neither this Agreement nor any term hereof may be amended except pursuant to a written instrument executed by the Partnership and FBR. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable as written by a court of competent jurisdiction, then such provision shall be given full force and effect to the fullest possible extent that it is valid, legal and enforceable, and the remainder of the terms and provisions herein shall be construed as if such invalid, illegal or unenforceable term or provision was not contained herein, but only to the extent that giving effect to such provision and the remainder of the terms and provisions hereof shall be in accordance with the intent of the parties as reflected in this Agreement.

Any such free writing prospectus consented to by FBR or by the Partnership, as the case may be, is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership represents and warrants that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

respect of any of the transactions contemplated by this Agreement, irrespective of whether or not FBR has advised or is advising the Partnership on other matters, and FBR has no obligation to the Partnership with respect to the transactions contemplated by this Agreement except the obligations expressly set forth in this Agreement;

b. it is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement;
