Notice to Secretary of Intention to Nominate Persons

for Election as Members of the Board of Managers

CONSTELLATION ENERGY PARTNERS MANAGEMENT, LLC

July 26, 2013

VIA MESSENGER AND MAIL

Constellation Energy Partners LLC

1801 Main Street, Suite 1300

Houston, TX 77002

Attention: Elizabeth A. Evans, Corporate Secretary

Re: Notice of Intent to Nominate Persons for Election as Members of the Board of Managers at the 2013 Annual Meeting of Members

Dear Ms. Evans:

We propose Helene S. Cohen and Steven M. Bradshaw as nominees for election to the Board of Managers of Constellation Energy Partners LLC (the “Company”). We propose that Ms. Cohen and Mr. Bradshaw will take the seats currently held by John N. Seitz and Richard S. Langdon, who we believe have not adequately increased unitholder value. We believe that each of our nominees has outstanding qualifications and experience that would add a unique mixture of both public and private sector expertise. We also believe that Ms. Cohen and Mr. Bradshaw would work constructively with both the Board of Managers and management to unlock value for all members. As such, we request that you include these individuals in the Board of Managers’ nominees for election at the 2013 annual meeting of members. If you do not, we will solicit proxies from the members of the Company for the election of Ms. Cohen and Mr. Bradshaw. At the annual meeting, we intend to support our nominees and Richard H. Bachmann.

The following notice is submitted to comply with Section 11.13 of the Second Amended and Restated Operating Agreement of the Company dated as of November 20, 2006 (as amended, the “Operating Agreement”):

Constellation Energy Partners Management, LLC (the “Nominating Unitholder”) hereby notifies you of its intent to nominate two (2) persons for election to the Board of Managers of the Company (the “Board”) by the holders of common units representing Class B Member Interests of the Company (the “Common Units”) at the 2013 annual meeting of members of the Company or any other meeting of members held in lieu thereof, and any adjournments, postponements, reschedulings or continuations thereof (the “Annual Meeting”). This letter, including the exhibits attached hereto, is collectively referred to as the “Notice.” The persons that the Nominating Unitholder intends to nominate for election to the Board as Class B Managers (as defined in the Operating Agreement) at the Annual Meeting are Helene S. Cohen and Steven M. Bradshaw. Ms. Cohen and Mr. Bradshaw are each referred to herein as a “Nominee”, and collectively, the “Nominees”. Biographical information for Ms. Cohen and Mr. Bradshaw is set forth in Exhibit A hereto.

Pursuant to Section 11.13 of the Operating Agreement, the undersigned hereby sets forth the following:

1. Information regarding each Nominee that is required to be disclosed in solicitations of proxies for the election of managers of the Company, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is set forth in Exhibit A and Exhibit B.

CUSIP No. 21038E 10 1 Page 17 of 41

2. The Nominees are willing to be nominated by the Nominating Unitholder. Each Nominee’s written consent to his or her nomination, to being named in any proxy statement as a nominee, and to serving as a manager of the Company if elected, is included as Exhibit C.

3. The Nominating Unitholder is the record owner of 5,918,894 Common Units and 485,065 Class A Units of the Company. The Nominating Unitholder is a holder of outstanding Common Units who is entitled to vote at the Annual Meeting. The name and address of the Nominating Unitholder is Constellation Energy Partners Management, LLC, 210 Park Avenue, Oklahoma City, OK 73102.

PostRock Energy Corporation (“PostRock”) as well as White Deer Energy L.P., White Deer Energy TE L.P. and White Deer Energy FI L.P., Edelman & Guill Energy L.P., Edelman & Guill Energy Ltd., Thomas J. Edelman and Ben A. Guill (collectively, the “White Deer Parties”) may be deemed beneficial owners of the Nominating Unitholder. PostRock and each of the White Deer Parties may be deemed to be the beneficial owners of 5,918,894 Common Units and 485,065 Class A Units of the Company. The address of PostRock is 210 Park Avenue, Suite 2750, Oklahoma City, OK 73102 and the address of each of the White Deer Parties is 667 Madison Avenue, 4^th Floor, New York, NY 10065.

4. The Nominating Unitholder intends to deliver a proxy statement and form of proxy to holders of a percentage of the outstanding Units of the Company reasonably believed by the Nominating Unitholder to be sufficient to elect the Nominees.

The information included herein and in the exhibits hereto represents the Nominating Unitholder’s best knowledge as of the date hereof. The Nominating Unitholder reserves the right, in the event that such information becomes inaccurate, to provide corrective information to the Company as soon as reasonably practicable, although the Nominating Unitholder does not undertake to update any information herein from and after the date hereof.

Should you have any questions regarding the information contained in this Notice, including the exhibits hereto, please contact Robert Seber of Vinson & Elkins LLP at (212) 237-0132 or rseber@velaw.com; or Kai Haakon Liekefett of Vinson & Elkins LLP at (713) 758-3839 or kliekefett@velaw.com.

Dear Ms. Cohen:

This letter agreement dated July 25, 2013 (this “Agreement”), is with reference to your agreement to become a nominee (a “Nominee”) of Constellation Energy Partners Management, LLC, a Delaware limited liability company (the “Nominating Party”), a wholly-owned subsidiary of PostRock Energy Corporation, a Delaware corporation (“PostRock”), for election as an independent manager of Constellation Energy Partners LLC, a Delaware limited liability company (the “Company”), in respect of the Company’s 2013 annual meeting of members or any special meeting of members of the Company called for a similar purpose, and any adjournment or postponement thereof.

A. Responsibilities of Nominee.

(a) You agree to be named as a Nominee in all materials prepared by the Nominating Party in connection with the solicitation of proxies from the Company’s members (the “Proxy Solicitation”), including, without limitation, all materials required under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder to be disclosed in a proxy statement, and any other materials prepared by the Nominating Party in connection with the Proxy Solicitation (collectively, the “Proxy Statement”). You further agree to (i) provide true and complete information concerning your background, experience, abilities and integrity as may be requested from time to time by the Nominating Party (including, without limitation, all information required for the Proxy Statement), and (ii) not to omit information that may be material to an understanding of your background, experience, abilities and integrity. In addition, you agree that, concurrently with your execution of this Agreement, you will execute a letter in the form attached as Exhibit A, in which you consent to being a Nominee, consent to being named in the Proxy Statement as a Nominee and, if elected, consent to serving as a manager of the Company. You agree that such consent, this Agreement and the information required hereunder may be disclosed by the Nominating Party in the Proxy Statement or otherwise. You agree, if elected, to serve as a manager of the Company, and in that capacity to act in the best interests of the Company and in accordance with the Second Amended and Restated Operating Agreement of the Company dated as of November 20, 2006 (as amended, the “Operating Agreement”) and to exercise your independent judgment in accordance with your fiduciary duties and the Operating Agreement in all matters that come before the board of managers of the Company (the “Board”). You agree that you will promptly provide the Nominating Party with (A) any updates to the information you have previously supplied to the Nominating Party in order to satisfy your obligations hereunder and (B) such additional information as may reasonably be requested by the Nominating Party in connection with your nomination for election to the Board.

(b) The parties acknowledge and agree that you are not an employee, an agent or other representative of the Nominating Party, and that you are independent of, and not controlled by or

CUSIP No. 21038E 10 1 Page 29 of 41

acting at the direction of, the Nominating Party and that, if elected, you will be acting as a manager of the Company, on behalf of the Company and all of the members of the Company and will in no way be controlled by or acting at the direction of the Nominating Party. You shall have no authority to act as an employee, an agent or other representative of the Nominating Party and you shall not represent the contrary to any person.

B. Responsibilities of Nominating Party.

Notwithstanding anything in this Agreement to the contrary, the Nominating Party shall not be obligated to nominate you to the Board or to commence or complete the Proxy Solicitation.

C. Expenses.

The Nominating Party agrees that for the period starting from the date of this Agreement and ending at the earlier of (a) your election to the Board (or if the election or qualification of members to the Board is contested on any grounds, such later date that such contest is resolved) and (b) the date you have been notified by the Nominating Party that it will not commence the Proxy Solicitation or has abandoned the Proxy Solicitation or will not nominate you to the Board or that the requisite number of votes for your election to the Board has not been obtained, the Nominating Party will (i) promptly reimburse you, upon your request, for all reasonable documented out-of-pocket expenses (including business class air travel and lodgings) incurred in the performance of your responsibilities as a Nominee, and (ii) directly pay for the reasonable documented legal fees and out-of-pocket expenses incurred by independent legal counsel selected collectively by and acting on behalf of all Nominees proposed by the Nominating Party as independent managers of the Company (the “Independent Counsel”).

D. Indemnification.

(a) As a material inducement to you to become a Nominee, the Nominating Party hereby agrees to indemnify, defend and hold harmless you from and against any and all losses, claims, damages, liabilities, judgments, costs, and expenses (including reasonable documented out-of-pocket fees and disbursements of counsel) (collectively, “Losses”) to which you may become subject or which you may incur in connection with being made, or threatened with being made, a party or witness (or in any other capacity) to any proceeding at law or in equity or before any governmental agency or board or any other body whatsoever (whether arbitral, civil, criminal, trial, appeal, administrative, formal, informal, investigative or other), arising out of or based upon your nomination for election to the Board, except to the extent such Loss arises or results from (i) your bad faith, willful misconduct or gross negligence or (ii) any untrue statement or omission by you or by the Nominating Party in reliance upon and in conformity with information furnished to the Nominating Party by you.

(b) In the event of the commencement or threatened commencement of any action, claim, suit, investigation or proceeding (each, a “Proceeding”) in respect of which you may seek indemnification from the Nominating Party hereunder, you will give prompt written notice thereof to the Nominating Party; provided, however, that the failure to so provide prompt notice shall not relieve the Nominating Party of its indemnification obligations hereunder except to the

CUSIP No. 21038E 10 1 Page 30 of 41

extent that the Nominating Party is materially prejudiced as a result thereof. The Nominating Party shall be entitled to control your defense in respect of any such Proceeding with counsel chosen by the Nominating Party. Notwithstanding the foregoing, the Nominating Party shall pay all fees and disbursements of Independent Counsel in respect of any such Proceeding; provided, however, you shall have the right to retain separate counsel at your own expense, except that the Nominating Party shall be responsible for the reasonable documented out-of-pocket fees and disbursements of such separate counsel if either (i) you and the Nominating Party mutually agree to the retention of such counsel or (ii) representation of you and other Nominees by the same counsel would be inappropriate due to actual or potential differing interests between you and them. The Nominating Party shall in no event be liable for any settlement by you of any such action effected without the prior written consent of the Nominating Party.

(c) The Nominating Party shall not settle, without your prior written consent (which consent may not be unreasonably withheld, conditioned or delayed), any Proceeding that would impose any penalty, obligation or limitation on you (other than monetary damages for which the Nominating Party agrees to be wholly responsible) or that would contain any language that could reasonably be viewed as an acknowledgement of wrongdoing on your part.

(d) Your rights to indemnification under this Agreement shall include the right to be advanced any and all expenses incurred in connection with any indemnifiable claim as such expenses are incurred.

(e) Notwithstanding anything to the contrary, if the Nominating Party has made payments to you pursuant to the indemnification and expense reimbursement provisions hereof and you subsequently are reimbursed by a third party therefor, you shall remit such subsequent reimbursement to the Nominating Party.

E. General.

The failure of a party to insist upon strict adherence to any term contained herein shall not be deemed to be a waiver of such party’s rights thereafter to insist upon strict adherence to that term or to any other term contained herein. In the event that any one or more provisions of this Agreement are deemed to be invalid, illegal or unenforceable by a court of competent jurisdiction, then such provision(s) shall be deemed severed to the least extent possible without affecting the validity, legality and enforceability of the remainder of this Agreement. This Agreement (i) shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict of laws principles; (ii) contains the entire understanding of the parties with respect to the subject matter contained herein and may not be modified or amended except by mutual written consent; and (iii) shall inure to the benefit of and be binding upon the parties and their respective heirs, representatives, successors, and permitted assigns.

CUSIP No. 21038E 10 1 Page 31 of 41

rights, interests or obligations hereunder to PostRock or the Company.
