WHEREAS, Parent, Parent GP, Javelina Merger Sub LLC, a Delaware limited liability company and wholly owned subsidiary of Parent (“Merger Sub”), and the Company entered into an Agreement and Plan of Merger, dated as of January 29, 2013 (as it may be amended from time to time, the “Merger Agreement”), providing for, among other things, subject to the terms and conditions of the Merger Agreement, the merger of Merger Sub with and into the Company (the “Merger”);

WHEREAS, as of the date hereof, the Unitholder is the record and beneficial owner of 12,897,029 Series A convertible preferred units of the Company (the “Preferred Units”) (such Preferred Units, the “Existing Units” and such Existing Units, together with any Common Units and Preferred Units acquired by the Unitholder after the date hereof, including as indicated in Section 4.1 below, the “Owned Units”); and

WHEREAS, as a condition to Parent’s willingness to enter into the Merger Agreement, Parent has required that the Unitholder agree, and the Unitholder has agreed, to enter into this Agreement.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration given to each party hereto, the receipt of which is hereby acknowledged, the parties agree as follows:

1. Agreement to Vote.

1.1 Agreement to Vote. The Unitholder hereby irrevocably and unconditionally agrees that, from the date hereof until the earlier of the (a) time that the Company Unitholder Approval has been obtained and (b) termination of this Agreement in accordance with Section 5.1 (the “Agreement Term”), at any meeting of the Unitholders of the Company at which the approval and adoption of the Merger Agreement and the transactions contemplated thereby is to be voted upon, however called, or any adjournment or postponement thereof, the Unitholder shall be present (in person or by proxy) and vote (or cause to be voted), to the extent entitled to vote thereon, all of its Owned Units at such time: (i) in favor of (A) adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger and (B) the approval of any proposal to adjourn or postpone the meeting to a later date if there are not sufficient votes for adoption of the Merger Agreement; (ii) against any Alternative Proposal; and (iii) against any action or agreement (including any amendment of any agreement) that would, or would reasonably be expected to, prevent or in any material respect impede or

delay the consummation of the Merger and the other transactions contemplated by the Merger Agreement.

1.2 Other Voting Rights. Except as permitted by this Agreement, throughout the Agreement Term, the Unitholder will continue to hold, and shall have the right to exercise, all voting rights related to the Owned Shares.

1.3 Grant of Irrevocable Proxy.

(a) The Unitholder hereby irrevocably appoints Parent and any designee of Parent, and each of them individually, as the Unitholder’s proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote at any annual or special meeting of Unitholders at which any of the matters described in Section 1.1. is to be considered during the Agreement Term, with respect to the Owned Shares as of the applicable record date, in each case solely to the extent and in the manner specified in Section 1.1; provided, however, that the Unitholder’s grant of the proxy contemplated by this Section 1.3 shall be effective if, and only if, the Unitholder has not delivered to the Secretary of the Company, at least two (2) business days prior to the applicable meeting, a duly executed irrevocable proxy card directing that the Owned Units be voted in accordance with Section 1.1. This proxy, if it becomes effective, is given to secure the performance of the duties of the Unitholder under this Agreement, and its existence will not be deemed to relieve the Unitholder of its obligations under Section 1.1. This proxy shall expire and be deemed revoked automatically at the expiration or termination of the Agreement Term.

(b) The Unitholder agrees and acknowledges that the proxy in Section 1.3(a) is: (i) given (x) in connection with the execution of the Merger Agreement and (y) to secure the performance of the Unitholder’s duties under this Agreement, (ii) coupled with an interest and may not be revoked except as otherwise provided in this Agreement and (iii) intended to be irrevocable prior to the expiration or termination of the Agreement Term.

5.9 Governing Law; Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, applicable to contracts executed in and to be performed entirely within that State.

(b) Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties hereto hereby irrevocably submits with regard to any such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve in accordance with this Section 5.9, (ii) any claim that it or its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by the applicable Law, any claim that (x) the suit, action or proceeding in such court is brought in an inconvenient forum, (y) the venue of such suit, action or proceeding is improper or (z) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

(c) EACH PARTY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, THE MERGER AGREEMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY OR THE ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND BY THE MERGER AGREEMENT.

5.10 Specific Performance; Exclusive Remedy. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, in accordance with this Section 5.10 in the Delaware Court of Chancery or any federal court sitting in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief as provided herein on the basis that (x) either party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. Each party further agrees that no party shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 5.10, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

5.11 Counterparts; Effectiveness. This Agreement may be executed in counterparts (each of which shall be deemed to be an original but all of which taken together shall constitute one and the same agreement) and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

5.12 Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms, provisions and conditions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

5.13 Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, agent, attorney, representative or affiliate of any party hereto or of any of its respective Affiliates (unless such Affiliate is expressly a party to this Agreement) shall have any liability (whether in contract or in tort) for any obligations or liabilities of such party arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby; provided, however, that nothing in this Section 5.13 shall limit any liability of the parties to this Agreement for breaches of the terms and conditions of this Agreement.

5.14 Interpretation.

(a) When a reference is made in this Agreement to an Article, a Section, Exhibit or Schedule, such reference shall be to an Article of, a Section of, or an Exhibit or Schedule to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation 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.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement.
