Shared G&A Services Allocation Shared G&A Services Allocation November 2009

2010 Shared Services Allocation Procedure . G&A is composed of two categories: . Third-party services that are performed on behalf of and directly billed to individual Quest entities (QRCP, QELP, & QMLP) . Shared services billed through Quest Energy Services (QES) . d S (QES) . QES shared services are composed of two components: . Directly allocable expenses, such as: — Expenses incurred by a QES employee performing a discreet project for a single Quest entity (for example, airfare for a trip to visit a Quest Midstream only customer) . Shared services costs, such as: — Salaries of QES employees that perform services for the benefit of multiple Quest entities — Shared overhead of QES employees (for example, rent/utilities of office space) . Shared services employee compensation allocations are updated monthly by each QES employee. Shared services overhead costs are allocated based on a compensation-weighted time allocation of all QES employees that is updated on a monthly basis . . The forecasted 2010 G&A budget, reflected in the projections, assumes a 12/31/09 recombination. Therefore, continued professional fees as a result of the now-forecasted 1st quarter 2010 recombination are not reflected in the current budget (1)

Allocation Mechanics Example 1 — A/P and Purchasing 1) QES Accounts Payable (A/P) employees perform services for each individual Quest entity as well as for the shared services entity (QES) 2) On a monthly basis, each A/P employee allocates the amount of their time they anticipate working on projects related to each Quest entity identified in Figure 1 below related to each Quest entity identified in Figure 1 below 3) Non-QES time allocations are grossed up to 100% (for use in compensation-weighted QES time allocation — see step 4) 4) Final monthly time of A/P employees for QES allocation is calculated, as sum of Fi 1 N b 2009 Q t A/P & P hi C All W k ht A. Direct allocation of non-QES overhead B. Allocation of QES overhead based on overall compensation-weighted monthly time allocation of all QES employees, which is calculated per the 100%-gross up of direct time allocation (per step 3) Figure 1: November 2009 Quest A/P & Purchasing Compensation Allocation Worksheet Employee QMLP QELP QRCP QES Name BSP + KPC Cherokee Appalachia Appalachia Other Overhead QMP QELP QRCP QMLP QELP QRCP QMLP QELP QRCP Employee 1 (Manager) Employee’s Time Allocation % to: Final Employee’s Time Spent on the Following: Employee’s Time Allocation % to: Convert Non-OKC to 100% for QES Calc 2 3 41 py ( g ) Employee 1 10% 45% 40% 0% 2% 3% 10% 85% 2% 10% 88% 2% 11% 87% 3% Employee 2 20% 35% 5% 5% 18% 17% 20% 40% 23% 24% 48% 28% 24% 50% 26% Employee 3 20% 50% 10% 10% 5% 5% 20% 60% 15% 21% 63% 16% 21% 63% 16% Employee 4 20% 40% 10% 10% 10% 10% 20% 50% 20% 22% 56% 22% 23% 56% 22% Employee 5 30% 40% 10% 10% 5% 5% 30% 50% 15% 32% 53% 16% 31% 53% 16% Employee 6 65% 5% 0% 25% 2% 3% 65% 5% 27% 67% 5% 28% 66% 7% 28% Employee 7 25% 25% 13% 13% 13% 12% 25% 38% 26% 28% 43% 29% 28% 44% 28% Compensation-Weighted Monthly Time Allocation Average (Excluding Co. 14) 25% 58% 17% 4A 4B (2)

Allocation Mechanics Example 2 — Management Team . Compensation of Quest management team and executive support staff are currently allocated 45%/45%/10% between QMLP, QELP, and QRCP respectively. Since mid-year 20092009, management efforts have been focused on recombination Per section 8.12 of the Merger Agreement executed July 2, 2009, “all costs and expenses incurred by the parties to this Agreement in connection with this Agreement and the transaction contemplated hereby shall be paid on the basis of 10% by QRCP,, 45% by QELP and 45% by QMLP” . After recombination is completed or is no longer being pursued, time allocations will be adjusted as needed at direction of individual employees on a monthly basis Final Employee’s Time Name Allocation %to: Last QMLP QELP QRCP President & CEO Employee 1 Employee 1 45% 45% 10% 45% 45% 10% Employee 2 45% 45% 10% Employee 3 45% 45% 10% Employee 4 45% 45% 10% Employee 5 45% 45% 10% Employee 6 45% 45% 10% Employee 7 45% 45% 10% 7 45% 45% 10% Employee 8 45% 45% 10% (3)

METHODOLOGY FOR DETERMINING ALLOCATED TAXES
OUTLINE OF TERMS OF TAX SHARING AGREEMENT

1. Overview. The Tax Sharing Agreement will provide for the allocation and sharing of income taxes among PostRock Energy Corporation (“Parent”), Quest Energy Partners, LLC and its subsidiaries (collectively, “QELLC”), Quest Midstream Partners, LLC and its subsidiaries (collectively “QMLLC”), and Quest Resource Corporation and its subsidiaries other than QMLLC and QELLC (collectively, “QRC”), for taxable periods beginning on or after the date of the recombination (“Tax Periods”).

2. Allocation and Sharing of U.S. Federal Income Taxes. For each Tax Period, Parent will file a consolidated U.S. federal income tax return which includes the income, gains, losses, deductions, and credits (“Tax Items”) of each of QRC, QELLC, and QMLLC for such Tax Period. Each of QRC, QELLC, and QMLLC will pay its respective allocable share of U.S. federal income taxes to Parent for each Tax Period. Such allocable share shall equal the amount of U.S. federal income tax that would have been owed to the IRS for such Tax Period by QRC, QELLC, or QMLLC, as the case may be, determined as if such entity were a C corporation that filed its own separate corporate return for U.S. federal income tax purposes and by taking into account (i) Tax Items generated by such entity during such Tax Period which are includible on Parent’s consolidated federal income tax return and (ii) any net operating losses, net capital losses, or tax credits generated by such entity in any other Tax Periods (excluding taxable periods ending on or prior to the date of the recombination) which could have been carried forward to such Tax Period if such entity were a C corporation that filed its own separate corporate return (and elected to waive any carryback of any such losses or credits) for U.S. federal income tax purposes for each Tax Period.

3. Allocation and Sharing of State Income Taxes. In those states where QRC, QELLC, or QMLLC are included in a combined, unitary or consolidated return filed by Parent, QRC’s, QELLC’s, or QMLLC’s respective shares of any such state income taxes payable to Parent shall be determined in a manner similar to that described in the preceding paragraph, but by applying applicable state tax law (rather than federal tax law) in determining the amount of Tax Items and net operating loss, tax credit or other tax attribute carryovers.

4. Payment of Tax Sharing Amounts. Any tax sharing amounts, including estimated taxes, payable by QRC, QELLC, or QMLLC for a Tax Period under the foregoing provisions shall be paid to Parent no later than 5 days prior to the date that such taxes are due and payable by Parent to the applicable taxing authority. In cases where estimated or interim tax payments are made to Parent for a Tax Period, QRC’s, QELLC’s, and QMLLC’s respective shares of the estimated or interim tax payments shall be determined in a manner similar to that described in the preceding paragraphs (but shall be based on estimates for the portions of the Tax Period covered by the estimated or interim tax payment).

5. Tax Adjustments. If any adjustment is subsequently made to the Tax Items of QRC, QELLC, or QMLLC pursuant to an original or amended return, refund claim, audit adjustment or administrative or judicial decision, QRC’s, QELLC’s, and QMLLC’s respective allocable shares of tax liability shall be readjusted accordingly and any payments required to conform to such adjustment shall be made to or by Parent.
