POSTROCK ENERGY CORPORATION AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2010
(Unaudited)
Note 1 — Basis of Presentation
     PostRock Energy Corporation (“PostRock”) is a Delaware corporation formed on July 1, 2009 for the purpose of effecting the recombination of Quest Resource Corporation (“QRCP”), Quest Energy Partners, L.P. (“QELP”) and Quest Midstream Partners, L.P. (“QMLP”). On July 2, 2009, PostRock, QRCP, QELP, QMLP and other parties thereto entered into a merger agreement pursuant to which QRCP, QELP and QMLP would recombine. The recombination was effected by forming a new publicly traded corporation, subsequently named PostRock, that, through a series of mergers and entity conversions, wholly owns all three entities. The recombination was completed on March 5, 2010. Since QRCP was the parent company which consolidated both QELP and QMLP prior to the recombination, the recombination was a transaction between equity interest holders within a consolidated entity rather than a business combination. The transaction was therefore accounted for on a historical cost basis. Since PostRock did not own any assets prior to the consummation of the recombination, the purpose of these condensed consolidated financial statements is to present the historical consolidated financial position and results of operations, cash flows and changes in equity of the predecessor entities (collectively referred to as “Predecessor”) prior to the recombination and to present such information for PostRock subsequent to the recombination. Unless the context requires otherwise, references to “we,” “us,” “our” or the “Company” are intended to mean and include the consolidated businesses and operations of our Predecessor for dates prior to March 6, 2010 and to the consolidated businesses and operations of PostRock and its subsidiaries for dates on or subsequent to March 6, 2010.
     The Company is an independent energy company involved in the acquisition, development, gathering, transportation, exploration, and production of oil and natural gas. Its principal operations and producing properties are located in the Cherokee Basin of southeastern Kansas and northeastern Oklahoma. The Cherokee Basin operations are currently focused on developing and gathering coal bed methane (“CBM”) gas production. The Company also owns and operates an interstate natural gas transmission pipeline.
     The Company also has development, exploration, production and gathering assets in the Appalachian Basin in West Virginia and New York. The Company’s Appalachian Basin operations are primarily focused in the Marcellus Shale. An investment advisory company has been engaged to pursue strategic alternatives, which may include a sale, of some of the Company’s Appalachian assets.
     The condensed consolidated balance sheet as of December 31, 2009, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements have been prepared by PostRock and the Predecessor pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods on a basis consistent with the annual audited consolidated financial statements. All such adjustments are of a normal recurring nature. Certain information, accounting policies and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the summary of significant accounting policies and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009 (the “2009 Form 10-K”).
     The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The operating results for the interim periods are not necessarily indicative of the results to be expected for the full year.

These transactions resulted in more favorable terms for its credit agreements and a $58.9 million repayment of outstanding debt. See Notes 2 and 3 for further details on the restructuring of the Company’s credit facilities and the White Deer investment.
     Prior to the equity investment and debt restructuring transactions described above, it was uncertain whether the Company would be able to meet its debt obligations as they came due. With the closing of the equity investment and the restructuring of the credit agreements, the Company has alleviated uncertainty regarding its ability to fund payment obligations in the near term.
Recent Accounting Pronouncements and Recently Adopted Accounting Pronouncements
     In January 2010, the Financial Accounting Standards Board (“FASB”) released Accounting Standards Update (“ASU”) 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements. The update requires reporting entities to provide information about movements of assets among Levels 1 and 2 of the three-tier fair value hierarchy established under FASB Accounting Standards Codification (“FASB ASC”) 820. The update also requires separate presentation (on a gross basis rather than as one net number) about purchases, sales, issuances, and settlements within the reconciliation of activity in Level 3 fair value measurements. The guidance is effective for any fiscal period beginning after December 15, 2009 except for the requirement to separately disclose purchases, sales, issuances, and settlements, which will be effective for any fiscal period beginning after December 15, 2010. The Company adopted the provisions of this update relating to disclosure on movement of assets among Levels 1 and 2 beginning with the quarter ended March 31, 2010. Other than additional disclosure required by the update, there was no material impact on its financial statements.
     In February 2010, the FASB released ASU 2010-09, Subsequent Events (Topic 855): Amendments to Certain Recognition and Disclosure Requirements which removed some contradictions between the requirements of GAAP and the SEC’s filing rules. As a result, public companies will no longer have to disclose the date of their financial statements in both issued and revised financial statements. The amendments became effective upon issuance of the update and the Company adopted the provisions of this update beginning with the quarter ended March 31, 2010 with no material impact on its financial statements.
Note 2 — Long-Term Debt
Former Credit Agreements
     On September 21, 2010, the Company completed a restructuring of its credit agreements. Prior to the restructuring, the Company had four credit agreements (the “Former Credit Agreements”) summarized as follows:
     (i) A term loan with an outstanding principal balance of approximately $125 million and no available capacity, secured by the Company’s assets owned by Quest Cherokee, LLC (the “Quest Cherokee Loan”);
     (ii) A second lien senior term loan with an outstanding principal balance of approximately $30.2 million, secured by a second lien on the Company’s assets owned by Quest Cherokee, LLC (the “Second Lien Loan”);
     (iii) A credit agreement with an outstanding principal balance of approximately $118.7 million secured by the Company’s assets owned by PostRock Midstream LLC and Bluestem Pipeline, LLC, which included the Bluestem gas gathering system and the KPC Pipeline (the “Midstream Loan”); and
     (iv) A credit agreement with an outstanding principal balance of approximately $43.8 million, secured by the Company’s Appalachian assets owned indirectly by PostRock Energy Services Corporation (the “PESC Loan”).
     The terms of the Company’s previous credit facilities and activity prior to the restructuring are described in Item 8. Financial Statement and Supplementary Data in the 2009 Form 10-K and in Part I, Item 1. of the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2010.

New Credit Agreements
     As of September 30, 2010, the Company has three credit agreements (the “New Credit Agreements”) summarized as follows:
     (i) A $350 million secured borrowing base revolving credit facility with an initial borrowing base of $225 million and outstanding borrowings of $190.0 million secured by, among other things, a first lien on the Company’s Cherokee Basin exploration and production assets, certain producing Appalachian production assets and the Cherokee Basin gas gathering system and a second lien on the Company’s interstate natural gas transportation pipeline (the “Borrowing Base Facility”);
     (ii) A term loan with an outstanding principal balance of $15 million, secured by, among other things, a first lien on the Company’s interstate natural gas transportation pipeline and a second lien on the Company’s Cherokee Basin exploration and production assets, certain producing Appalachian production assets and the Cherokee Basin gas gathering system (the “Secured Pipeline Loan”); and
     (iii) A term loan with an outstanding principal balance of $43.8 million, secured by the Company’s assets owned by Quest Eastern Resource LLC (“QER”), which include certain producing and non-producing Appalachian properties and the Appalachian gas gathering system, and a pledge of the equity of QER (the “QER Loan”).

Borrowing Base Facility
     The Borrowing Base Facility with PostRock Energy Services Corporation (“PESC”) and PostRock MidContinent Production, LLC (formerly known as Bluestem Pipeline, LLC and the successor by merger to Quest Cherokee, LLC) (“MidContinent”) as borrowers, Royal Bank of Canada (“RBC”) as administrative and collateral agent, and the lenders party thereto is a secured borrowing base facility with an initial borrowing base of $225 million and is guaranteed by PostRock and certain of its subsidiaries.
     The Borrowing Base Facility is the result of restructuring the Quest Cherokee Loan, the Second Lien Loan and all but $15 million of the outstanding indebtedness under the Midstream Loan (see “ — Secured Pipeline Loan” below) and amending and restating the related agreements in whole or in part.
     Under the terms of the Borrowing Base Facility, MidContinent and PESC prepaid the outstanding indebtedness under the Quest Cherokee Loan in an amount equal to approximately $19.2 million. In consideration therefor, the lenders completely restructured the credit agreements relating to the Quest Cherokee Loan and the Second Lien Loan with the Borrowing Base Facility, partially restructured the Midstream Loan, and secured the Borrowing Base Facility with the same assets that secured the Quest Cherokee Credit Agreement and the Second Lien Loan Agreement (including the assets of MidContinent, which include all of the oil and gas exploration assets located in

F-7


Table of Contents

the Cherokee Basin and all of the oil and gas exploration assets located in the Appalachian basin that are not owned by QER) in addition to the Bluestem gas gathering system (which had formerly partially secured the Midstream Loan).
     Other material terms of the Borrowing Base Facility include the following:
Covenants The Borrowing Base Facility contains affirmative and negative covenants that are customary for transactions of this type, including financial covenants that prohibit PESC, MidContinent and any of their subsidiaries (with certain exceptions) from:
permitting the borrowers’ current ratio (ratio of consolidated current assets (as defined in the agreement) to consolidated current liabilities (as defined in the agreement)) at any fiscal quarter-end to be less than or equal to 1.0 to 1.0;
permitting the borrowers’ interest coverage ratio (ratio of adjusted consolidated EBITDA to consolidated interest charges) at any fiscal quarter-end to be less than or equal to 3.0 to 1.0 measured on a trailing four quarter basis; and
permitting the borrowers’ leverage ratio (ratio of cash adjusted consolidated funded debt to adjusted consolidated EBITDA for the four fiscal quarters ending on the applicable fiscal quarter-end) (1) commencing with the quarter ending September 30, 2010, and ending on the quarter ending March 31, 2011, to be greater than or equal to 4.5 to 1.0, (2) commencing with the quarter ending June 30, 2011, and ending on the quarter ending March 31, 2012, to be greater than or equal to 4.0 to 1.0, and (3) commencing with the quarter ending June 30, 2012, and continuing until the maturity date to be greater than or equal to 3.5 to 1.0.
Interest Rate LIBOR plus 3.50% to 4.00% or, at the borrowers option, Base Rate plus 2.50% to 3.00%, in each case depending on utilization. The interest rate on the outstanding borrowings at September 30, 2010, was 4.01%.
Maturity Date June 30, 2013.
Capital Expenditures The borrowers are obligated to make minimum capital expenditures in the cumulative aggregate amount of (1) $5.0 million for the six-month period ending December 31, 2010, (2) $10.0 million for the nine-month period ending March 31, 2011, (3) $17.5 million for the 12-month period ending June 30, 2011, and (4) $25.0 million for the 15-month period ending September 30, 2011. If the borrowers have not expended the required amounts by December 31, 2010, the borrowers are entitled to an additional quarter to expend that amount. In the event the borrowers have not expended the minimum aggregate capital expenditure amount required to be expended by March 31, 2011, June 30, 2011 or September 30, 2011, the borrowing base will be reduced by an amount equal to the shortfall.
Borrowing Base Redetermination The first borrowing base redetermination with respect to the indebtedness under the Borrowing Base Facility will be effective on July 31, 2011 and based on the Company’s March 31, 2011 oil and natural gas reserves. After July 31, 2011, the borrowing base redeterminations by the lenders will be effective every April 30th and October 31st until maturity taking into account the value of MidContinent’s proved reserves. In addition, the borrowers, during each period between scheduled redeterminations of the borrowing base, and, the required lenders, after the redetermination effective April 30, 2012, have the right to initiate a redetermination of the borrowing base between each scheduled redetermination, provided that no more than two such redeterminations may occur in a 12-month period. In addition, upon a material disposition of assets and a material acquisition of oil and gas properties, and in certain other limited circumstances, the borrowing base will or may be redetermined. If the borrowing base is reduced in connection with a redetermination, the borrowers can elect to either repay the entire deficiency within 30 days, repay the deficiency in six equal monthly installments, or contribute additional properties to increase the value of the collateral to support the prior borrowing base.

Payments Principal is required to be repaid on the maturity date. The borrowers are required to make a mandatory prepayment of principal upon the occurrence of any of the following events: (a) a material disposition of assets; (b) a sale of the Appalachian assets owned by MidContinent; (c) a change of control occurring after September 21, 2010; and (d) the existence of a borrowing base deficiency. Interest payments are due (i) at the end of each LIBOR interest period but in no event less frequently than quarterly in the case of LIBOR loans or (ii) quarterly in the case of Base Rate loans.
Security Interest The Borrowing Base Facility is secured by (i) a first lien on all of PostRock’s assets except for the Appalachian properties owned by QER, the equity of QER, three lateral gas pipelines owned by Quest Transmission Company, LLC, the KPC Pipeline and the other assets of KPC and (ii) a second lien on the KPC Pipeline and the other assets of KPC.
Events of Default Events of default are customary for transactions of this type and include, without limitation, non-payment of principal when due, non-payment of interest, fees and other amounts within three business days after the due date, failure to perform or observe covenants and agreements (subject to a 30-day cure period in certain cases), representations and warranties not being correct in any material respect when made, certain acts of bankruptcy or insolvency, cross defaults to other material indebtedness, non-appealable judgment in a material amount is entered against a borrower or its affiliate, ERISA violations, invalidity of loan documents, dissolution, collateral impairment, borrowing base deficiencies, and change of control.
Secured Pipeline Loan
     The Secured Pipeline Loan with PESC and PostRock KPC Pipeline, LLC (“KPC”) as borrowers, RBC as administrative and collateral agent, and the lenders party thereto is a $15 million term loan secured by a first lien on the KPC Pipeline and the other assets of KPC, and by a second lien on the assets on which the lenders under the Borrowing Base Facility have a first lien.
     Under the terms of the Secured Pipeline Loan, PESC and KPC prepaid approximately $14,700,000 of the outstanding indebtedness under the Midstream Loan in exchange for the assignment by the lenders under the Midstream Loan of approximately $89,000,000 of the indebtedness owing under the Midstream Loan to the lenders under the Borrowing Base Facility. The remaining $15,000,000 of such indebtedness was retained under the Secured Pipeline Loan.
Other material terms of the Secured Pipeline Loan include the following:
Covenants The Secured Pipeline Loan contains affirmative and negative covenants that are customary for credit agreements of this type. The financial covenants in the Secured Pipeline Loan are substantially the same as the financial covenants in the Borrowing Base Facility.
Interest Rate LIBOR plus 3.75% or, at the borrowers option, Base Rate plus 2.75%. The interest rate on September 30, 2010, was 4.01%.
Maturity Date February 28, 2012.
Payments Principal payments in the amount of $500,000 are due monthly for the first six months beginning October 21, 2010, and $1,000,000 monthly thereafter, as well as monthly interest payments. Prepayments are required to be made in the following amounts: (a) net available cash from the sale of the KPC Pipeline or the equity of KPC and (b) total outstanding amounts upon a change of control.
Events of Default Events of default under the Secured Pipeline Loan are customary for transactions of this type and include, without limitation, non-payment of principal when due, non-payment of interest, fees and other amounts within three business days after the due date, failure to perform or observe covenants and agreements (subject to a 30-day cure period in certain cases), representations and warranties not being correct in any material respect when made, certain acts of bankruptcy or insolvency, cross defaults to other material indebtedness, non-

appealable judgment in a material amount is entered against a borrower or its affiliate, ERISA violations, invalidity of loan documents, dissolution, collateral impairment, and change of control.
QER Loan
     As part of the closing of our amended and restated credit facilities, PESC, QER and RBC entered into an assumption agreement whereby QER assumed all of PESC’s rights and obligations as borrower under the PESC Loan. In addition, QER, as borrower, entered into the third amended and restated credit agreement with RBC in the amount of approximately $43.8 million. In connection therewith, RBC, the lender under the PESC Loan released PESC from any liability or obligation to repay amounts owing under the PESC Loan and all of the guarantors thereunder from their respective guarantees of the indebtedness owing under the PESC Loan and (except for QER) from their respective mortgages and security agreements. RBC also released the liens on all the collateral owned by PESC, other than the Appalachian assets owned by QER and the equity of QER; and agreed to reconvey the overriding royalty interests to their respective grantors (or their designees) at such time as the Appalachian assets or equity of QER are sold. Accordingly, under the QER Loan, RBC has recourse only to QER, its assets and the equity of QER.
Other material terms of the QER Loan include the following:
Covenants The QER Loan contains non-financial affirmative and negative covenants that are customary for credit agreements of this type. There are no financial covenants contained in the QER Loan.
Interest Rate LIBOR plus 4.00% or, at the borrowers option, Base Rate plus 3.00%. The weighted average interest rate on September 30, 2010, was 4.27%.
Maturity Date June 30, 2013.
Payments No interim principal payments are scheduled under the QER Loan. Interest payments are not required until on or after March 31, 2011, and then are due quarterly, in the case of Base Rate Loans, or at the end of each LIBOR interest period, but in no event less frequently than quarterly, in the case of LIBOR loans. Mandatory prepayment of the net cash proceeds upon a disposition of the Appalachian assets owned by QER is required. The principal plus accrued interest is due at maturity.
Security Interest The QER Loan is secured by a first priority lien on the assets of QER and a pledge by PESC of QER’s equity.
Events of Default Events of default are customary for transactions of this type and include, without limitation, non-payment of principal when due, non-payment of interest, fees and other amounts within three business days after the due date, failure to perform or observe covenants and agreements (subject to a 30-day cure period in certain cases), representations and warranties not being correct in any material respect when made, certain acts of bankruptcy or insolvency, non-appealable judgment in a material amount is entered against a borrower or its affiliate, ERISA violations, invalidity of loan documents, dissolution, collateral impairment, and change of control.
     In connection with the QER Loan, PostRock entered into an asset sale agreement with RBC that allows PostRock to sell QER or substantially all of its assets and, in the event the proceeds are not adequate to repay the QER Loan in full, PostRock has agreed to pay a portion of such shortfall in cash, stock or a combination thereof.
     Troubled debt restructuring — The interest rate margin under the QER Loan of 3%-4% is lower than the margin under the previous PESC Loan, which was 10%. Due to a reduction in the interest rate coupled by the Company’s recent financial difficulties, the QER Loan restructuring met the criteria under FASB ASC 470-60 Debt—Troubled Debt Restructurings by Debtors (“FASB ASC 470-60”) to be classified as a troubled debt restructuring. In accordance with accounting guidance, the Company evaluated whether the sum of future cash flows under the QER Loan would be less than the amount payable under the original loan (PESC Loan), which would require a gain to be recognized on the debt restructuring. These cash flows are indeterminate as they depend on proceeds from the sale

F-10


Table of Contents

of QER’s assets. Since such proceeds could potentially be sufficient to repay the QER Loan in full, the Company determined that it was not necessary to recognize a gain on the debt restructuring. As required by FASB ASC 470-60, the Company expensed $0.9 million in fees incurred to restructure the debt which are reflected in interest expense, net, on the condensed consolidated statements of operations. The Company evaluated the restructuring of its former credit facilities that resulted in the Borrowing Base Facility and Secured Pipeline Loan and determined that they were not troubled debt restructurings.
Debt fees
     Upon the successful restructuring of the Company’s Former Credit Agreements, the unamortized balance of debt fees related to those agreements was $1.8 million. The Company wrote off the unamortized balance of $1.8 million in accordance with the provisions of FASB ASC 470-50 Debt—Modifications and Extinguishments.
     The Company incurred a total of $6.8 million in fees related to its New Credit Facilities and the White Deer equity investment of which $4.4 million related to the Borrowing Base Facility and $0.3 million related to the Secured Pipeline Loan were capitalized, $0.9 million related to the QER Loan was recorded as an expense, and the remaining $1.2 million related to the White Deer equity investment was recorded as a reduction to additional paid-in capital. The write-off of unamortized debt fees and the fees related to the QER Loan have been recognized as a component of interest expense, net, on the condensed consolidated statements of operations.

     Redeemable Preferred Shares — On September 21, 2010, the Company issued to White Deer 6,000 shares of the Company’s Series A Cumulative Redeemable Preferred Stock (the “Series A Preferred Stock”), 190,476.19 shares of its Series B Voting Preferred Stock (the “Series B Preferred Stock”) and warrants to purchase 19,047,619 shares of the Company’s common stock. The preferred stock and warrants were issued in exchange for a $60 million equity infusion from White Deer.
     The Series A Preferred Stock is entitled to a cumulative dividend of 12% per year on its liquidation preference, compounded quarterly. The liquidation preference totaled $60 million on the closing date of the equity investment and will increase by the amount of accrued and unpaid dividends. The Company is not required to pay cash

F-11


Table of Contents

dividends until July 1, 2013. Any dividends prior to that time not paid in cash will accrue as additional liquidation preference. Subsequent to July 13, 2013, dividends are required to be paid in cash and any payment default after that date will increase the accrual of the additional liquidation preference during the default period from a rate of 12% to 14%. The Company is required to redeem the Series A Preferred Stock on March 21, 2018 at 100% of the liquidation preference. From and after one year from the issuance date until such mandatory redemption date, the Company will have the option to redeem all or a specified minimum portion of the Series A Preferred Stock at 110% of the liquidation preference. The holders of the Series A Preferred Stock have the right to require the Company to purchase their shares on the occurrence of specified change in control events at 110% of the liquidation preference. In the case of specified defaults by the Company, including the failure to pay dividends for any quarterly period after July 1, 2013, and until the defaults are cured, the holders of the Series A Preferred Stock have the right to appoint two additional directors to the Board of Directors. The Series A Preferred Stock do not vote generally with the common stock, but have specified approval rights with respect to, among other things, changes to the Company’s certificate of incorporation that affect the Series A Preferred Stock, cash dividends on the common stock or other junior stock, redemptions or repurchases of common stock or other capital stock, increases in the size of the Board of Directors, changes to specified debt agreements and changes to the Company’s business.
     The warrants issued at the closing of the investment are exercisable for a total of 19,047,619 shares of common stock at an exercise price of $3.15 per share which represents an approximate 5% premium to the closing price of the common stock on September 1, 2010, the day before the transaction was publicly announced. Prior to July 1, 2013, the Company may elect to pay dividends on the Series A Preferred Stock in cash. During this period, if such dividends are not paid in cash on a dividend payment date, the Company will issue additional warrants exercisable for a number of shares of common stock equal to the amount of dividends that are not paid on that dividend payment date divided by the closing price of the common stock on the trading date immediately preceding the dividend payment date. The exercise price of the warrants will be such closing price. The warrants, including any additional warrants, are exercisable for 90 months following the applicable issuance date, but not before the earlier of January 19, 2011 or a change in control of the Company. Each warrant is coupled, and may only be transferred as a unit, with a number of one one-hundredths of a share, or a “fractional share,” of Series B Preferred Stock equal to the number of shares of common stock purchasable upon exercise of the warrant. The warrants and the Series B Preferred Stock may not be transferred separately. If and when the warrant is exercised, the holder of the warrant will be required to deliver to the Company, as part of the payment of the exercise price, a number of fractional shares of Series B Preferred Stock equal to the number of shares of common stock purchased upon such exercise. The holders of the warrants have the right to pay the exercise price in cash, by electing a cashless exercise (whereby the holder will receive the excess of the market price of the common stock over the exercise price in shares of common stock valued at the market price) or by tendering shares of Series A Preferred Stock with a liquidation preference equal to the exercise price. If the market price of the common stock exceeds 300% of the exercise price for a specified period of time and other conditions are satisfied, the Company may require the holders of the warrants to exercise warrants to purchase up to 50% of shares covered thereby, but in the aggregate not less than 750,000 shares or more than 50% of the trading volume of the common stock over the preceding 20 trading days.
     The holders of Series B Preferred Stock are entitled to vote in the election of directors and on all other matters submitted to a vote of the holders of common stock of the Company, with the holders of Series B Preferred Stock and the holders of common stock voting together as a single class. Each fractional share of Series B Preferred Stock has one vote. The voting rights of each share of Series B Preferred Stock may not be exercised by any person other than the holder of the warrant that is part of the unit with such share or fractional share and will expire on the expiration date of such warrant. The Series B Preferred Stock has no dividend rights and a nominal liquidation preference. Until December 31, 2011, the holders of the Series B Preferred Stock and their affiliates are limited to 45% of the votes applicable to all outstanding voting stock, which limit includes any common stock held by them. After December 31, 2011, the limit only restricts the voting of the Series B Preferred Stock, and the holders and their affiliates may vote any shares of common stock held by them without regard to that limit.
     The Series A Preferred Stock has been recorded outside of permanent equity and liabilities, in the Company’s condensed consolidated balance sheet because the settlement provisions of the warrants allow White Deer to “net exercise” the warrants by requiring the Company to repay the Series A Preferred Stock at the liquidation preference to offset the strike price of the warrants that would otherwise be due from White Deer in cash. Absent this provision, the Series A Preferred Stock would have met the definition of mandatorily redeemable preferred stock under FASB ASC 480 Distinguishing Liabilities from Equity (“FASB ASC 480”) which would have required recognition as a

F-12


Table of Contents

liability. This provision allows the Series A Preferred Stock to effectively be convertible to common stock at the election of White Deer. In the event that White Deer exercises the warrants without net-exercising the Series A Preferred Stock back to the Company as payment for the strike price of the warrants, the Company will be required to reclassify a proportionate amount of Series A Preferred Stock from temporary equity to liabilities as that portion of the Series A Preferred Stock is no longer convertible to common stock.
     The $60 million in gross proceeds from White Deer was allocated among the Series A Preferred Stock, Series B Preferred Stock and the warrants. The warrants were recognized at a fair value of $10.8 million on the date of issuance and recorded as additional paid in capital in our condensed consolidated balance sheet. The preferred stock was subsequently recognized in an amount equal to the $60 million in proceeds net of the fair value of the warrants resulting in $49.2 million recorded in temporary equity related to the Series A Preferred Stock and approximately $2,000 recorded in equity related to the par value of the Series B Preferred Stock. As the Series A Preferred Stock is initially recorded at a discount, it will be accreted to its full redemption value over the 7 1/2 year term under the interest method in accordance with FASB ASC 480. Offering fees of $1.2 million were recorded as a reduction of additional paid in capital.
     The Company used a Monte Carlo stock option pricing simulation to value the warrants. The warrants are classified as Level 3 within the fair value hierarchy established by FASB ASC 820 because observable market data is not available. The assumptions used in the model for the warrant valuation included the exercise price of $3.15 per share and inputs relating to stock price drift and daily volatility. The Series A Preferred Stock also contains a put option whereby White Deer can put the stock to the Company at 110% of the liquidation preference upon a change in control. Under FASB ASC 815, “Derivatives and Hedging,” (“FASB ASC 815”) it was determined that the put option is both indexed to the Company’s own stock and classified in stockholder’s equity as the underlying Series A Preferred Stock is classified as temporary equity. Accordingly, the put option is scoped out of FASB ASC 815 and does not require separate accounting as a bifurcated derivative.

Note 4 — Derivative Financial Instruments
     The Company is exposed to commodity price risk and management believes it prudent to periodically reduce exposure to cash-flow variability resulting from this volatility. Accordingly, the Company enters into certain derivative financial instruments in order to manage exposure to commodity price risk inherent in its oil and gas production operations. Specifically, the Company may utilize futures, swaps and options. Futures contracts and commodity swap agreements are used to fix the price of expected future oil and gas sales at major industry trading locations, such as Henry Hub, Louisiana for gas and Cushing, Oklahoma for oil. Basis swaps are used to fix or float the price differential between the price of gas at Henry Hub and various other market locations. Options are used to fix a floor and a ceiling price (collar) for expected future oil and gas sales. Derivative financial instruments are also used to manage commodity price risk inherent in customer pricing requirements and to fix margins on the future sale of natural gas.
     Settlements of any exchange-traded contracts are guaranteed by the New York Mercantile Exchange (NYMEX) or the Intercontinental Exchange and are subject to nominal credit risk. Over-the-counter traded swaps, options and physical delivery contracts expose us to credit risk to the extent the counterparty is unable to satisfy its settlement commitment. The Company monitors the creditworthiness of each counterparty and assesses the impact, if any, on fair value. In addition, it routinely exercises its contractual right to net realized gains against realized losses when settling with our swap and option counterparties.

     The Company accounts for its derivative financial instruments in accordance with FASB ASC 815 Derivatives and Hedging (“FASB ASC 815”). FASB ASC 815 requires that every derivative instrument (including certain derivative instruments embedded in other contracts) be recorded on the balance sheet as either an asset or liability measured at its fair value. FASB ASC 815 requires that changes in the derivative’s fair value be recognized currently in earnings unless specific hedge accounting criteria are met or exemptions for normal purchases and normal sales (“NPNS”) as permitted by FASB ASC 815 exist. The Company does not designate its derivative financial instruments as hedging instruments for financial accounting purposes and, as a result, it recognizes the change in the respective instruments’ fair value currently in earnings. In accordance with FASB ASC 815, the table below outlines the classification of derivative financial instruments on the condensed consolidated balance sheet and their financial impact in the condensed consolidated statements of operations as of and for the periods indicated (in thousands):

     Settlements in the normal course of maturities of derivative financial instrument contracts result in cash receipts from or cash disbursement to derivative contract counterparties and are, therefore, realized gains or losses. Changes in the fair value of derivative financial instrument contracts are included in income currently with a corresponding increase or decrease in the balance sheet fair value amounts.

     During October 2010, the Company entered into new crude oil swap contracts for 48,000 barrels with an average contract price of $85.90 per barrel for 2011 and 42,000 barrels with an average price of $87.90 per barrel for 2012.
Note 5 — Fair Value Measurements
     The Company’s financial instruments include derivatives, debt, cash, receivables and payables. The carrying value of the Company’s debt approximates fair value due to the variable nature of the interest rates. The carrying amount of cash, receivables and payables approximates fair value because of the short-term nature of those instruments.
     As discussed in Note 3, White Deer’s investment in the Company included 7 1/2 year warrants to purchase common stock at an exercise price of $3.15 per share. Warrants to White Deer are recognized at fair value on the

F-15


Table of Contents

date of issuance and recorded as a component of additional paid-in capital on the condensed consolidated balance sheet. See Note 3 for a discussion on the valuation of these warrants.
     Effective January 1, 2009, the Company adopted FASB ASC 820 Fair Value Measurements and Disclosures (“FASB ASC 820”), which applies to its nonfinancial assets and liabilities for which it discloses or recognizes at fair value on a nonrecurring basis, such as asset retirement obligations and other assets and liabilities. Fair value is the exit price that the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date.
     FASB ASC 820 also establishes a hierarchy that prioritizes the inputs used to measure fair value. The three levels of the fair value hierarchy are as follows:
  Level 1 — Quoted prices available in active markets for identical assets or liabilities as of the reporting date.
  Level 2 — Pricing inputs other than quoted prices in active markets included in Level 1 which are either directly or indirectly observable as of the reporting date. Level 2 consists primarily of non-exchange traded commodity derivatives.
  Level 3 — Pricing inputs include significant inputs that are generally less observable from objective sources.
     The Company classifies assets and liabilities within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement of each individual asset and liability taken as a whole. Certain derivatives are classified as Level 3 because observable market data is not available for all of the time periods for which the Company has derivative instruments. As observable market data becomes available for all of the time periods, these derivative positions will be reclassified as Level 2. The availability of market based information starting in July 2010 has allowed the Company to reclassify a portion of its swap contracts tied to Southern Star prices from Level 3 to Level 2 in the third quarter of 2010.
     ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements requires reporting entities to provide information about movements of assets among Levels 1 and 2 of the three-tier fair value hierarchy established under FASB ASC 820. There were no movements between Levels 1 and 2 for the three month or nine month periods ending September 30, 2010 and 2009.
     The following table sets forth, by level within the fair value hierarchy, the assets and liabilities that were measured at fair value on a recurring basis as of the dates indicated (in thousands):

     Risk management assets and liabilities in the table above represent the current fair value of all open derivative positions, excluding those derivatives designated as NPNS. These derivative instruments are classified as “Derivative financial instrument assets” or “Derivative financial instrument liabilities” in the condensed consolidated balance sheet.
     In order to determine the fair value of amounts presented above, the Company utilizes various factors including market data and assumptions that market participants would use in pricing assets or liabilities as well as assumptions about the risks inherent in the inputs to the valuation technique. These factors include not only the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits, letters of credit and

F-16


Table of Contents

parental guarantees), but also the impact of nonperformance risk on the Company’s liabilities. The Company utilizes observable market data for credit default swaps to assess the impact of non-performance credit risk when evaluating its assets from counterparties.
     In certain instances, the Company may utilize internal models to measure the fair value of derivative instruments. Generally, the Company uses similar models to value similar instruments. Valuation models utilize various inputs which include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, other observable inputs for the assets or liabilities, and market-corroborated inputs, which are inputs derived principally from or corroborated by observable market data by correlation or other means.

Note 7 — Share-Based Compensation
     Immediately prior to the recombination, there were 1,155,327 restricted shares of QRCP, 945,593 phantom units of QELP and 732,784 restricted units of QMLP that were unvested. In the recombination, 118,816 restricted shares of QRCP, 7,500 phantom units of QELP and 67,838 restricted units of QMLP were subject to immediate vesting immediately prior to the closing and, at closing, these awards converted to 36,416 shares of PostRock common stock. PostRock’s predecessor and the predecessor’s consolidated subsidiaries recognized $0.4 million of compensation expense related to the accelerated vesting discussed above. All remaining unvested awards were converted to 595,923 PostRock restricted share awards. In addition, 670,000 of QRCP stock options converted to 38,525 PostRock stock options upon effectiveness of the recombination. For the three months ended September 30, 2010, total share-based compensation related to stock awards and options of PostRock or its predecessor and consolidated subsidiaries of its predecessor was $0.4 million, compared to $0.3 million for the three months ended September 30, 2009. The stock based compensation expense was $1.0 million and $0.8 million for the periods from March 6 to September 30, 2010, and January 1 to March 5, 2010, respectively. The stock based compensation expense was $1.1 million for nine month period ended September 30, 2009. Share-based compensation is included in general and administrative expense on our statements of operations. The granting of future stock awards and options to employees subsequent to the recombination is governed by PostRock’s 2010 Long-Term Incentive Plan

(the “LTIP”). As of September 30, 2010, there were 835,964 shares available under the LTIP for future stock awards and options. Subsequent to the recombination, during 2010, 54,036 shares of PostRock stock were granted to officers and directors of the Company while 137,860 restricted shares and 18,975 stocks options were forfeited as a result of employee turnover. Total share-based compensation to be recognized on unvested stock awards and options as of September 30, 2010, is $1.2 million over a weighted average period of 1.53 years.

(1)   FASB ASC 260 Earnings Per Share requires participating securities to be included in the allocation of earnings when calculating basic earnings per share, or EPS, under the two-class method. During periods of losses, these securities are not included in the basic EPS share computation. For the period from March 6 to September 30, 2010, there were no unvested participating share-based awards.
 
(2)   Restricted stock awards were excluded for the three and nine month periods ended September 30, 2009, because the Predecessor reported a net loss for those periods.
Note 9— Impairment of Oil and Gas Properties
     At the end of each quarterly period, the unamortized cost of oil and natural gas properties, net of related deferred income taxes, is limited to the full cost ceiling, computed as the sum of the estimated future net revenues from proved reserves using twelve-month average prices discounted at 10%, and adjusted for related income tax effects (ceiling test). Prior to December 31, 2009, the present value was calculated using spot market prices at the balance sheet date. Under full cost accounting rules, any ceiling test write-downs of oil and natural gas properties may not be reversed in subsequent periods. Since the Company does not designate its derivative financial instruments as hedges, it is not allowed to use the impacts of the derivative financial instruments in its ceiling test computation. As a result, decreases in commodity prices which contribute to ceiling test write-downs may be offset by mark-to-market gains which are not reflected in the Company’s ceiling test results.
     Under the present full cost accounting rules, the Company is required to compute the after-tax present value of proved oil and natural gas properties using twelve-month average prices for oil and natural gas at the balance sheet

date. The base for the Company’s spot prices for natural gas is Henry Hub and for oil is Cushing, Oklahoma. The Predecessor had previously recognized a ceiling test impairment of $102.9 million during the first quarter of 2009 while no impairment has resulted in 2010. Natural gas, which is sold at other natural gas marketing hubs where the Company conducts operations, is subject to prices which reflect variables that can increase or decrease spot natural gas prices at these hubs such as market demand, transportation costs and quality of the natural gas being sold. Those differences are referred to as the basis differentials. In the past, basis differentials resulted in natural gas prices for the Company’s Cherokee Basin production to be lower than Henry Hub, except in Appalachia, where the Company has typically received a premium to Henry Hub. The Company may face further ceiling test write-downs in future periods, depending on the level of commodity prices, drilling results and well performance.
     The calculation of the ceiling test is based upon estimates of proved reserves. There are numerous uncertainties inherent in estimating quantities of proved reserves, in projecting the future rates of production and in the timing of development activities. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Results of drilling, testing, production and changes in economics related to the properties subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserve estimates are often different from the quantities of oil and natural gas that are ultimately recovered.
Note 10 — Income Taxes
     The effective income tax rate for all periods presented was less than the federal statutory rate primarily due to the effect of changes in the valuation allowance on the net deferred tax asset.
     On March 5, 2010, the Company completed the recombination and, on September 21, 2010, the White Deer equity investment. Both transactions resulted in an ownership change for purposes of Internal Revenue Code Section 382 and significantly restrict the Company’s ability to utilize its otherwise available net operating loss (“NOL”) carryforwards. Accordingly, the Company has reduced its gross deferred tax assets for the NOL carryforwards that it does not believe will be utilized because of the restrictions imposed by Section 382, and has also reversed the associated valuation allowance recorded by the Company in prior periods against such NOLs.
     The Company has recorded no provision for income taxes for the pre-tax earnings for the three months and nine months ended September 30, 2009, for the three months ended September 30, 2010 and for the period from March 6, 2010 through September 30, 2010, as it believes that such earnings can be offset by its remaining unutilized NOLs from prior periods. The Company will continue to record a full valuation allowance against the remaining net deferred tax assets because it does not believe that it is more likely than not that the future tax benefits will be realized.

Paul Rosen, individually and on behalf of all others similarly situated v. Quest Energy Partners LP, Quest Energy GP LLC, Quest Resource Corporation, Jerry Cash, and David E. Grose , Case No. 08-cv-978-M, U.S. District Court for the Western District of Oklahoma, filed September 17, 2008
     Four putative class action complaints were filed in the United States District Court for the Western District of Oklahoma naming QRCP, QELP and Quest Energy GP, LLC, the general partner of the predecessor of QELP (“QEGP”), and certain of their then current and former officers and directors as defendants. The complaints were filed by certain stockholders on behalf of themselves and other stockholders who purchased QRCP common stock between May 2, 2005 and August 25, 2008 and QELP common units between November 7, 2007 and August 25, 2008. The complaints assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b-5 promulgated thereunder, and Sections 11 and 15 of the Securities Act of 1933. The complaints allege that the defendants violated the federal securities laws by issuing false and misleading statements and/or concealing material facts concerning certain unauthorized transfers of funds from subsidiaries of QRCP to entities controlled by QRCP’s former chief executive officer, Mr. Jerry D. Cash. The complaints also allege that, as a result of these actions, QRCP’s stock price and the unit price of QELP was artificially inflated during the class period. On December 29, 2008, the Court consolidated these complaints. Mediation was held among the parties on February 2 and April 2, 2010. An agreement to settle the federal court securities actions, both individual and class action, all federal court shareholder derivative suits and all state court derivative suits was reached in principle. The settlement is subject to court approval. On July 9, 2010, a stipulation of settlement was filed in the consolidated action. On August 13, 2010, the Court entered an order preliminarily approving the settlement. Notice of the proposed settlement has been sent to members of the putative class, who have until November 15, 2010, to submit a claim or to opt out of the settlement. Pursuant to the settlement agreement, the defendants may elect to terminate the settlement if more than five percent of the class members opt out. A hearing on final approval of the proposed settlement is set for November 29, 2010. If approved by the Court, all of the referenced lawsuits will be dismissed with prejudice to refiling. The Company is contributing $1.0 million to the proposed settlement of the lawsuits. In addition, the Company has agreed to pay approximately $0.4 million representing a portion of associated defense costs of certain individual defendants. As of September 30, 2010, the Company has paid $1.3 million of the amounts above. While the Company has recorded an accrual of $1.4 million through the third quarter of 2010, there can be no assurance that final approval of the settlement will be granted by the Court, that the defendants will not terminate the settlement if a sufficient number of the class members opt out or that the final settlement amount will equal the amount of the accrual.
     Federal Individual Securities Litigation
Bristol Capital Advisors v. Quest Resource Corporation, Inc., Jerry Cash, David E. Grose, and John Garrison, Case No. CIV-09-932, U.S. District Court for the Western District of Oklahoma, filed August 24, 2009
     On August 24, 2009, a complaint was filed in the United States District Court for the Western District of Oklahoma naming QRCP and certain then current and former officers and directors as defendants. The complaint was filed by an individual stockholder of QRCP. The complaint asserts claims under Sections 10(b) and 20(a) of the Exchange Act. The complaint alleges that the defendants violated the federal securities laws by issuing false and misleading statements and/or concealing material information concerning unauthorized transfers from subsidiaries of QRCP to entities controlled by QRCP’s former chief executive officer, Mr. Jerry D. Cash. The complaint also alleges that QRCP issued false and misleading statements and or/concealed material information concerning a misappropriation by its former chief financial officer, Mr. David E. Grose, of $1 million in company funds and receipt of unauthorized kickbacks of approximately $850,000 from a company vendor. The complaint also alleges that, as a result of these actions, QRCP’s stock price was artificially inflated when the plaintiff purchased their shares of QRCP common stock. As discussed above, an agreement to settle has been reached in principle. The settlement is subject to court approval and there can be no assurance that final approval of the settlement will be granted by the Court.

The complaint asserts claims for breach of fiduciary duty, waste of corporate assets, unjust enrichment, conversion, disgorgement under the Sarbanes-Oxley Act of 2002, and aiding and abetting breaches of fiduciary duties against the individual defendants and vendors and professional negligence and breach of contract against the external auditors.

     Royalty Owner Class Action
Hugo Spieker, et al. v. Quest Cherokee, LLC, Case No. 07-1225-MLB, U.S. District Court for the District of Kansas, filed August 6, 2007
     The Company was named as a defendant in a putative class action lawsuit filed by several royalty owners in the U.S. District Court for the District of Kansas. The putative class consists of all royalty and overriding royalty owners in the Kansas portion of the Cherokee Basin. Plaintiffs contend that the Company failed to properly make royalty payments by, among other things, paying royalties based on sale volumes rather than wellhead volumes, by allocating expenses in excess of actual costs, by improperly allocating production costs and marketing costs to royalty owners, and by failing to pay interest on royalty payments made late. The Company has filed an answer, denying plaintiffs’ claims.
     The parties participated in a mediation in August 2010 and continue to engage in settlement discussions. The Court has extended the previously entered stay of discovery to provide the parties with time to continue settlement discussions and/or conduct another mediation. The Company has recorded an accrual of $1.0 million related to this case.

royalties of plaintiffs and have engaged in self-dealing contracts and agreements resulting in a less than market price for production. Plaintiffs seek unspecified actual and punitive damages. Limited discovery has taken place and no deadlines have been set. The parties have agreed to participate in a mediation and are working toward scheduling the same.
Contractual Commitments
     The Company has numerous contractual commitments in the ordinary course of business, debt service requirements and operating lease commitments. Commitments as of December 31, 2009, are disclosed within Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations-Contractual Obligations in the Company’s 2009 Form 10-K. In July 2010, the Company entered into an investment advisory agreement in conjunction with its efforts to sell certain oil and gas properties in Appalachia. The agreement does not require a minimum payment but instead specifies payment amounts that are contingent on the successful sale of the properties and amount of proceeds from such sale. Other than the preceding contract and the restructuring of the Company’s credit agreements as described in Note 2, as of September 30, 2010, there were no other material changes to the Company’s commitments compared with December 31, 2009.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Forward-looking statements
     Various statements in this report, including those that express a belief, expectation, or intention, as well as those that are not statements of historical fact, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include those regarding projections and estimates concerning the timing and success of specific projects; financial position; business strategy; budgets; amount, nature and timing of capital expenditures; drilling of wells and construction of pipeline infrastructure; acquisition and development of oil and natural gas properties and related pipeline infrastructure; timing and amount of future production of oil and natural gas; operating costs and other expenses; estimated future net revenues from oil and natural gas reserves and the present value thereof; cash flow and anticipated liquidity; funding of our capital expenditures; ability to meet our debt service obligations; and other plans and objectives for future operations.
     When we use the words “believe,” “intend,” “expect,” “may,” “will,” “should,” “anticipate,” “could,” “estimate,” “plan,” “predict,” “project,” or their negatives, or other similar expressions, the statements which include those words are usually forward-looking statements. When we describe strategy that involves risks or uncertainties, we are making forward-looking statements. The factors impacting these risks and uncertainties include, but are not limited to:
    current weak economic conditions;
 
    volatility of oil and natural gas prices;
 
    benefits or effects of the recombination;
 
    increases in the cost of drilling, completion and gas gathering or other costs of developing and producing our reserves;
 
    our debt covenants;
 
    access to capital, including debt and equity markets;
 
    results of our hedging activities;
 
    drilling, operational and environmental risks; and
 
    regulatory changes and litigation risks.
     You should consider carefully the statements in Part I, Item 1A. “Risk Factors” of our 2009 Form 10-K and Part II, Item 1A. and other sections of this Quarterly Report on Form 10-Q, which describe factors that could cause our actual results to differ from those set forth in the forward-looking statements.
     We have based these forward-looking statements on our current expectations and assumptions about future events. The forward-looking statements in this report speak only as of the date of this report; we disclaim any obligation to update these statements unless required by securities law, and we caution you not to rely on them unduly. Readers are urged to carefully review and consider the various disclosures made by us in our reports filed with the SEC, which attempt to advise interested parties of the risks and factors that may affect our business, financial condition, results of operation and cash flows. If one or more of these risks or uncertainties materialize, or if the underlying assumptions prove incorrect, our actual results may vary materially from those expected or projected.

Overview of PostRock
     PostRock Energy Corporation (“PostRock”) is a Delaware corporation formed on July 1, 2009, solely for the purpose of effecting a recombination of Quest Resource Corporation (“QRCP”), Quest Energy Partners, L.P. (“QELP”) and Quest Midstream Partners, L.P. (“QMLP”). Prior to the consummation of the recombination on March 5, 2010, we did not conduct any business operations other than incidental to our formation and in connection with the transactions contemplated by the merger agreement for the recombination. Following the recombination, we own QRCP, QELP and QMLP and their successors as direct or indirect wholly-owned subsidiaries and have no significant assets other than the stock and other voting securities of our subsidiaries.
     We are an independent energy company involved in the acquisition, development, gathering, transportation, exploration, and production of oil and natural gas. Our principal operations and producing properties are located in the Cherokee Basin of southeastern Kansas and northeastern Oklahoma. The Cherokee Basin operations are currently focused on developing and gathering coal bed methane (“CBM”) gas production. We also own and operate an interstate natural gas transmission pipeline.
     In addition, we own development, exploration, production and gathering assets in the Appalachian Basin in West Virginia and New York. Our Appalachian Basin operations are primarily focused in the Marcellus Shale. An investment advisory company has been engaged to pursue strategic alternatives, which may include a sale, of some of the our Appalachian assets.
     Unless the context requires otherwise, references to “we,” “us” and “our” are intended to mean and include the consolidated businesses and operations of QRCP and its subsidiaries (our “Predecessor”), including QELP and QMLP and their respective subsidiaries, for dates prior to March 6, 2010, and to the consolidated businesses and operations of PostRock and its subsidiaries for dates on or subsequent to March 6, 2010.
     Our highlights in 2010 include:
    Successfully completed the recombination of QRCP, QELP and QMLP.
 
    Completed an equity investment by White Deer Energy L.P. (“White Deer”) of $60.0 million in gross proceeds.
 
    Restructured our credit facilities to provide for more favorable debt covenants, borrowing base provisions and interest rates while permitting us to further simplify our organizational structure and return to a drilling program.
 
    Reduced debt by $80.5 million from December 31, 2009 to September 30, 2010.
 
    Completed and connected 141 new wells in the Cherokee Basin.
 
    Returned approximately 232 wells in the Cherokee Basin to production.
 
    Generated cash flows from operations of $35.3 million for the nine months ended September 30, 2010.
Results of Operations
     The following discussion of financial condition and results of operations should be read in conjunction with the condensed consolidated financial statements and the related notes, which are included elsewhere in this report. Our results of operations for the nine months ended September 30, 2010, represent the combined results of our Predecessor and PostRock. The results of operations for the three and nine months ended September 30, 2009, are those of our Predecessor. We conduct our business through two reportable business segments: (i) oil and natural gas production, and (ii) natural gas pipelines, including transporting, gathering, treating and processing natural gas.

     Oil and Gas Sales Oil and gas sales increased $3.2 million, or 17.2%, to $21.5 million during the three months ended September 30, 2010, from $18.3 million during the three months ended September 30, 2009. This increase was primarily due to an increase in average realized natural gas prices which resulted in increased revenues of $5.0 million partially offset by lower production volumes which decreased revenue by $1.8 million. Natural gas equivalent volumes declined to 5.0 Bcfe for the three months ended September 30, 2010, or 10.1%, from 5.5 Bcfe for the three months ended September 30, 2009. Natural gas production decreased primarily due to a lack of development activity beginning in the latter part of 2008 through 2009 as we faced liquidity constraints. Our lack of development activity has resulted in a limited number of new wells coming online, causing us to rely on existing wells to sustain production. These wells have been subject to a natural decline in production. Although we completed and connected 141 wells in the Cherokee Basin during the first nine months of 2010, these wells are still in the early phase of production and did not contribute significant volume to our production in the third quarter of 2010. Our average realized prices on an equivalent basis (Mcfe) increased to $4.33 per Mcfe for the three months ended September 30, 2010, from $3.33 per Mcfe for the three months ended September 30, 2009.
     Oil and Gas Operating Expenses Oil and gas operating expenses consist of oil and gas production costs and transportation expense. Oil and gas operating expenses decreased $6.1 million, or 30.9%, to $13.6 million for the three months ended September 30, 2010, from $19.7 million for the three months ended September 30, 2009.
     Oil and gas production costs, which include lease operating expenses, severance taxes and ad valorem taxes, decreased $3.1 million, or 35.4%, to $5.6 million during the three months ended September 30, 2010, from $8.7 million during the three months ended September 30, 2009. The decrease was primarily due to lower ad valorem taxes of $2.7 million and lower lease operating expenses of $0.6 million partially offset by higher severance taxes of $0.2 million. Ad valorem taxes were lower as we revised our anticipated ad valorem tax to reflect lower reserve values assessed by taxing authorities. Lease operating expenses decreased as a result of lower labor costs. Production costs were $1.14 per Mcfe for the three months ended September 30, 2010, as compared to $1.59 per Mcfe for the three months ended September 30, 2009.
     Transportation expense decreased $3.0 million, or 27.4%, to $8.0 million during the three months ended September 30, 2010, from $11.0 million during the three months ended September 30, 2009. The decrease was primarily due to a decrease in the contracted transportation fee as well as lower volumes. Transportation expense was $1.61 per Mcfe for the three months ended September 30, 2010, as compared to $2.00 per Mcfe for the three months ended September 30, 2009.
     Depreciation, Depletion and Amortization We are subject to variances in our depletion rates from period to period due to changes in our oil and natural gas reserve quantities, production levels, product prices and changes in the depletable cost basis of our oil and natural gas properties. Our depreciation, depletion and amortization decreased approximately $6.7 million, or 67.6%, during the three months ended September 30, 2010, to $3.2 million from $9.9 million during the three months ended September 30, 2009. On a per unit basis, we had a decrease of $1.15 per Mcfe to $0.65 per Mcfe during the three months ended September 30, 2010, from $1.80 per Mcfe during the three months ended September 30, 2009. This decrease was primarily due to an increase to our reserves as a result of higher prices in 2010 which decreased our rate per unit in the current quarter compared to the prior year quarter.

     Third party natural gas pipeline revenue decreased $1.8 million, or 31.8%, to $3.8 million during the three months ended September 30, 2010, from $5.6 million during the three months ended September 30, 2009. The decrease was primarily due to the loss of a significant interstate pipeline customer during the fourth quarter of 2009 and renegotiated contracts at lower volumes and rates with another significant existing interstate pipeline customer. Also contributing to the decrease was a decline in the transportation rate and volumes of third-party gas transported on our Cherokee Basin gas gathering pipeline network.
     Intercompany natural gas pipeline revenue decreased $3.0 million, or 27.4%, to $8.0 million during the three months ended September 30, 2010, from $11.0 million during the three months ended September 30, 2009. The decrease was primarily due to a lower contracted rate in 2010 along with a decline in volume transported.
     Pipeline Operating Expense Pipeline operating expense decreased $1.5 million, or 18.8%, to $6.7 million during the three months ended September 30, 2010, from $8.2 million during the three months ended September 30, 2009. Contributing to the decrease in operating expense were lower ad valorem taxes.
     Depreciation and Amortization Depreciation and amortization expense decreased $2.4 million, or 60.0%, to $1.7 million during the three months ended September 30, 2010, from $4.1 million during the three months ended September 30, 2009. Depreciation and amortization was lower due to an impairment of $165.7 million on our long lived pipeline related assets recorded during the fourth quarter of 2009, which subsequently lowered the depreciable basis of these assets.
     Unallocated Items
     General and Administrative Expenses General and administrative expenses decreased $6.6 million, or 58.9%, to $4.7 million during the three months ended September 30, 2010, from $11.3 million during the three months ended September 30, 2009. Expenses decreased as a result of higher legal, accounting and consulting fees in 2009 for the reaudit and restatement of previously issued financials and the recombination of the predecessor entities as well as fees to financial advisors, coupled with a reduction in expenses related to certain employee benefits during the current year period.
     Gain from Derivative Financial Instruments Gain from derivative financial instruments increased $23.5 million, or 268.7%, to $32.3 million for the three months ended September 30, 2010, from $8.8 million for the three months

     Oil and Gas Sales Oil and gas sales increased $12.0 million, or 21.2%, to $68.7 million during the nine months ended September 30, 2010 from $56.7 million during the nine months ended September 30, 2009. This increase was primarily due to an increase in average realized natural gas prices which resulted in increased revenues of $18.4 million partially offset by lower production volumes which decreased revenue by $6.4 million.

completed and connected 141 wells in the Cherokee Basin during the first nine months of 2010, these wells are still in the early phase of production and did not contribute significant volume to our production in the first half of 2010. Oil production decreased primarily due to the impact of storm damage sustained to our Central Oklahoma oilfield in May 2010. This damage was repaired and production from the field resumed by the end of the second quarter of 2010. Our average realized prices on an equivalent basis (Mcfe) increased to $4.68 per Mcfe for the nine months ended September 30, 2010, from $3.42 per Mcfe for the nine months ended September 30, 2009.
     Oil and Gas Operating Expenses Oil and gas operating expenses consist of oil and gas production costs and transportation expense. Oil and gas operating expenses decreased $11.0 million, or 20.0%, to $43.9 million for the nine months ended September 30, 2010, from $54.9 million for the nine months ended September 30, 2009.
     Oil and gas production costs, which include lease operating expenses, severance taxes and ad valorem taxes, decreased $3.3 million, or 13.8%, to $20.4 million during the nine months ended September 30, 2010, from $23.7 million during the nine months ended September 30, 2009. The decrease was a result of lower lease operating expenses of $3.2 million and lower ad valorem taxes of $0.9 million partially offset by higher severance taxes of $0.8 million. Lease operating expenses decreased as a result of lower labor costs and lower costs for repairs and maintenance. Ad valorem taxes were lower as we revised our anticipated ad valorem tax to reflect lower reserve values assessed by taxing authorities. Production costs were $1.39 per Mcfe for the nine months ended September 30, 2010, as compared to $1.43 per Mcfe for the nine months ended September 30, 2009.
     Transportation expense decreased $7.7 million, or 24.8%, to $23.5 million during the nine months ended September 30, 2010, from $31.2 million during the nine months ended September 30, 2009. The decrease was primarily due to a decrease in the contracted transportation fee as well as lower volumes. Transportation expense was $1.60 per Mcfe for the nine months ended September 30, 2010, as compared to $1.89 per Mcfe for the nine months ended September 30, 2009.
     Depreciation, Depletion and Amortization We are subject to variances in our depletion rates from period to period due to changes in our oil and natural gas reserve quantities, production levels, product prices and changes in the depletable cost basis of our oil and natural gas properties. Our depreciation, depletion and amortization decreased approximately $16.9 million, or 62.2%, during the nine months ended September 30, 2010, to $10.2 million from $27.1 million during the nine months ended September 30, 2009. On a per unit basis, we had a decrease of $0.94 per Mcfe to $0.70 per Mcfe during the nine months ended September 30, 2010, from $1.64 per Mcfe during the nine months ended September 30, 2009. This decrease was primarily due to the impairment of our oil and gas properties in the first quarter of 2009 along with the impact to our reserves from higher prices in 2010, both of which decreased our rate per unit in the first half of 2010 compared to the prior year period.

     Pipeline Revenue Total natural gas pipeline revenue decreased $17.1 million, or 32.6%, to $35.2 million for the nine months ended September 30, 2010 from $52.3 million for the nine months ended September 30, 2009.
     Third party natural gas pipeline revenue decreased $9.3 million, or 44.2%, to $11.7 million during the nine months ended September 30, 2010, from $21.0 million during the nine months ended September 30, 2009. The decrease was primarily due to the loss of a significant interstate pipeline customer during the fourth quarter of 2009 and renegotiated contracts at lower volumes and rates with another significant interstate pipeline customer. Also contributing to the decrease was a decline in the transportation rate and volumes for third-party gas transported on our Cherokee Basin gas gathering pipeline network. The overall decrease was partially offset by seasonal transportation agreements beginning in November 2009 through March 2010.
     Intercompany natural gas pipeline revenue decreased $7.7 million, or 24.8%, to $23.5 million during the nine months ended September 30, 2010, from $31.2 million during the nine months ended September 30, 2009. The decrease was primarily due to a lower contracted rate in 2010 along with a decline in volume transported.
     Pipeline Operating Expense Pipeline operating expense decreased $2.2 million, or 9.8%, to $20.1 million during the nine months ended September 30, 2010, from $22.3 million during the nine months ended September 30, 2009. The decrease was a result of lower operational costs in our Cherokee Basin gas gathering operations due to reduced compression costs as well as a decrease in ad valorem taxes.
     Depreciation and Amortization Depreciation and amortization expense decreased $7.4 million, or 60.5%, to $4.8 million during the nine months ended September 30, 2010, from $12.2 million during the nine months ended September 30, 2009. Depreciation and amortization was lower due to an impairment of $165.7 million on our long lived pipeline related assets recorded during the fourth quarter of 2009, which subsequently lowered the depreciable basis of these assets.

current year period. The decreases from 2009 were partly offset by higher costs in 2010 for the estimated lawsuit settlement costs along with costs to refinance our debt. Our estimate of settlement costs includes costs associated with our federal securities lawsuits as discussed in Part I, Item 1, Note 11—Commitments and Contingencies. As indicated in our discussion, an agreement to settle all of the securities lawsuits has been reached with preliminary approval from the court. The settlement is subject to final court approval. We have agreed to contribute $1.4 million to the settlement of the securities lawsuits of which $1.3 million had been paid as of September 30, 2010.
     Gain from Derivative Financial Instruments Gain from derivative financial instruments increased $44.4 million, or 142.9%, to $75.5 million for the nine months ended September 30, 2010, from $31.1 million for the nine months ended September 30, 2009. We recorded a $54.4 million unrealized gain and $21.1 million realized gain on our derivative contracts for the nine months ended September 30, 2010, compared to a $52.0 million unrealized loss and $83.1 million realized gain for the nine months ended September 30, 2009. During June 2009 we amended or exited certain above market derivative contracts in order to generate $26 million for the repayment of a borrowing base deficiency associated with our credit facilities. Unrealized gains and losses are attributable to changes in oil and natural gas prices and volumes hedged from one period end to another.
     Interest expense, net Interest expense, net, increased $1.7 million, or 8.2%, to $22.4 million during the nine months ended September 30, 2010, from $20.7 million during the nine months ended September 30, 2009. The increase is primarily due to a $3.6 million increase in amortizing or writing off debt amendment fees offset by lower interest charges on outstanding debt due to a reduced level of debt.
Liquidity and Capital Resources
     Overview Our operating cash flows have historically been driven by the quantities of our production of oil and natural gas and the prices received from the sale of this production and revenue generated from our pipeline operating activities. Prices of oil and natural gas have historically been very volatile and can significantly impact the cash from the sale of our oil and natural gas production. Use of derivative financial instruments helps mitigate this price volatility. Cash expenses also impact our operating cash flow and consist primarily of oil and natural gas property operating costs, severance and ad valorem taxes, interest on our indebtedness and general and administrative expenses. We believe we have adequate credit availability and liquidity to meet our operating expenses and debt service requirements. The following discussion of cash flows from various activities for the nine months ended September 30, 2010, represents the combined cash flows of our Predecessor and of PostRock.
     Our primary sources of liquidity for the nine months ended September 30, 2010 were cash generated from our operations and proceeds from the White Deer equity investment. At September 30, 2010, we had $1.3 million in cash and cash equivalents and the following outstanding amounts on our bank credit facilities:

     Cash Flows from Operating Activities Cash flows provided by operating activities totaled $35.3 million for the nine months ended September 30, 2010, compared to $64.6 million for the nine months ended September 30, 2009. Cash flows from operating activities were lower as a result of a reduction in realized gains on derivative contracts from $83.1 million for the nine months ended September 30, 2009, to $21.1 million for the months ended September

30, 2010. During June 2009, we amended or exited certain above market derivative contracts in order to generate $26 million for the repayment of a borrowing base deficiency associated with our credit facilities. The decrease was offset by a reduction of payables during the nine months ended September 30, 2009.
     Cash Flows from Investing Activities Cash flows used in investing activities totaled $22.4 million for the nine months ended September 30, 2010 as compared to cash flows provided by investing activities of $2.3 million for the nine months ended September 30, 2009. The cash flows from investing activities in 2009 were due to proceeds from the sale of oil and natural gas properties in Pennsylvania for $8.7 million. Capital expenditures were $22.9 million and $6.4 million for the nine months ended September 30, 2010 and 2009, respectively. Our capital expenditures were lower in 2009 due to liquidity constraints during that period. The following table sets forth our capital expenditures, including costs we have incurred but not paid, by major categories for the nine months ended September 30, 2010:

     Cash Flows from Financing Activities Cash flows used in financing activities totaled $32.5 million for the nine months ended September 30, 2010 as compared to cash flows used in financing activities of $46.8 million for the nine months ended September 30, 2009. The cash used in financing activities during 2010 was primarily due to the repayment of $89.0 million of bank borrowings partially offset by proceeds from the White Deer equity investment of $60.0 million and borrowings under our revolving credit facility of $3.0 million. We also incurred $6.5 million in costs related to the equity investment and debt restructuring. Cash used for the nine months ended September 30, 2009 was primarily due to the repayment of $49.1 million of bank borrowings offset by $2.9 million of additional borrowings.
Sources of Liquidity in 2010 and Capital Requirements
     On September 21, 2010, we completed a $60 million equity investment by White Deer. White Deer purchased $60 million initial liquidation preference of our Series A Cumulative Redeemable Preferred stock (the “Series A Preferred Stock”). White Deer also purchased 7 1/2 year warrants to purchase $60 million of our common stock at an exercise price of $3.15 per share, which represents an approximate 5% premium to our closing stock price on September 1, 2010, the day before the transaction was publicly announced. The Series A Preferred Stock is entitled to a cumulative dividend of 12% per year on its liquidation preference, compounded quarterly. Prior to July 1, 2013, we can elect to to pay dividends on the Series A Preferred Stock in cash. During this period, if such dividends are not paid in cash, the liquidation preference of the Series A Preferred Stock will increase by the amount of the dividend and we will issue additional warrants exercisable for shares of our common stock. We are required to redeem the Series A Preferred Stock on March 21, 2018 at 100% of the liquidation preference. See Note 3 in Part I, Item 1. of this Quarterly Report for further details on the securities issued as a result of White Deer’s investment.
     Along with the equity investment described above, on September 21, 2010, our credit agreements were restructured. Concurrent with the restructuring and equity investment, we repaid $58.9 million of our debt. The restructuring resulted in more favorable debt covenants, borrowing base provisions and interest rates for our credit facilities while permitting us to further simplify our organizational structure. The restructured credit agreements provide us with a long term source of liquidity with only $9.0 million of the outstanding balance due within the next twelve months. Prior to the equity investment and debt restructuring transactions described above, it was uncertain whether we would be able to meet our debt obligations as they came due. With the closing of the equity investment

Table of Contents

and the restructuring of the credit agreements, we have alleviated uncertainty regarding our ability to fund payment obligations in the near term.
Former Credit Agreements
     Prior to the restructuring, we had four credit agreements summarized as follows:
     (i) A term loan with an outstanding principal balance of approximately $125 million and no available capacity, secured by our assets owned by Quest Cherokee, LLC (the “Quest Cherokee Loan”);
     (ii) A second lien senior term loan with an outstanding principal balance of approximately $30.2 million, secured by a second lien on our assets owned by Quest Cherokee, LLC (the “Second Lien Loan”);
     (iii) A credit agreement with an outstanding principal balance of approximately $118.7 million secured by our assets owned by PostRock Midstream LLC and Bluestem Pipeline LLC, which included the Bluestem gas gathering system and the KPC Pipeline (the “Midstream Loan”); and
     (iv) A credit agreement with an outstanding principal balance of approximately $43.8 million, secured by our Appalachian assets owned indirectly by PostRock Energy Services Corporation (the “PESC Loan”).
     The terms of our previous credit facilities and activity prior to the restructuring are described in Item 8. Financial Statement and Supplementary Data in our 2009 Form 10-K and in Part I, Item 1. of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2010.
New Credit Agreements
     As of September 30, 2010, we have three credit agreements (the “New Credit Agreements”) summarized as follows:
     (i) A $350 million secured borrowing base revolving credit facility with an initial borrowing base of $225 million and outstanding borrowings of $190.0 million secured by, among other things, a first lien on our Cherokee Basin exploration and production assets, certain producing Appalachian production assets and the Cherokee Basin gas gathering system and a second lien on our interstate natural gas transportation pipeline (the “Borrowing Base Facility”);
     (ii) A term loan with an outstanding principal balance of $15 million, secured by, among other things, a first lien on our interstate natural gas transportation pipeline and a second lien on our Cherokee Basin exploration and production assets, certain producing Appalachian production assets and the Cherokee Basin gas gathering system (the “Secured Pipeline Loan”); and
     (iii) A term loan with an outstanding principal balance of $43.8 million, secured by our assets owned by Quest Eastern Resource LLC (“QER”), which include certain producing and non-producing Appalachian properties and the Appalachian gas gathering system, and a pledge of the equity of QER (the “QER Loan”).
Borrowing Base Facility
     The Borrowing Base Facility with PostRock Energy Services Corporation (“PESC”) and PostRock MidContinent Production, LLC (formerly known as Bluestem Pipeline, LLC and the successor by merger to Quest Cherokee, LLC) (“MidContinent”), as borrowers, RBC as administrative and collateral agent, and the lenders party thereto is a secured borrowing base facility with an initial borrowing base of $225 million and is guaranteed by PostRock and certain of its subsidiaries.
     The Borrowing Base Facility is the result of restructuring the Quest Cherokee Loan, the Second Lien Loan and all but $15 million of the outstanding indebtedness under the Midstream Loan (see “ — the Secured Pipeline Loan” below) and amending and restating the related agreements in whole or in part.
     Under the terms of the Borrowing Base Facility, MidContinent and PESC prepaid the outstanding indebtedness under the Quest Cherokee Loan in an amount equal to approximately $19.2 million. In consideration therefor, the

11


Table of Contents

lenders completely restructured the credit agreements relating to the Quest Cherokee Loan and the Second Lien Loan with the Borrowing Base Facility, partially restructured the Midstream Loan, and secured the Borrowing Base Facility with the same assets that secured the Quest Cherokee Credit Agreement and the Second Lien Loan Agreement (including the assets of MidContinent, which include all of the oil and gas exploration assets located in the Cherokee Basin and all of the oil and gas exploration assets located in the Appalachian basin that are not owned by QER) in addition to the Bluestem gas gathering system (which had formerly partially secured the Midstream Loan). See Note 2 in Part I, Item 1. of this Quarterly Report on Form 10-Q for a summary of the material terms of the Borrowing Base Facility.
     As of October 30, 2010, the outstanding balance on the Borrowing Base Facility was $190.5 million with an additional $1.5 million in outstanding letters of credit, resulting in approximately $33 million of additional availability.
Secured Pipeline Loan
     The Secured Pipeline Loan with PESC and PostRock KPC Pipeline, LLC (“KPC”) as borrowers, RBC as administrative and collateral agent, and the lenders party thereto is a $15 million term loan secured by a first lien on the KPC Pipeline and the other assets of KPC, and by a second lien on the assets on which the lenders under the Borrowing Base Facility have a first lien.
     Under the terms of the Secured Pipeline Loan, PESC and KPC prepaid approximately $14,700,000 of the outstanding indebtedness under the Midstream Loan in exchange for the assignment by the lenders under the Midstream Loan of approximately $89,000,000 of the indebtedness owing under the Midstream Loan to the lenders under the Borrowing Base Facility. The remaining $15,000,000 of such indebtedness was retained under the Secured Pipeline Loan. See Note 2 in Part I, Item 1. of this Quarterly Report on Form 10-Q for a summary of the material terms of the Secured Pipeline Loan.
     As of October 30, 2010, the outstanding balance on the Secured Pipeline Loan was $14.5 million with no additional availability.
QER Loan
     As part of the closing of our amended and restated credit facilities, PESC, QER and RBC entered into an assumption agreement whereby QER assumed all of PESC’s rights and obligations as borrower under the PESC Loan. In addition, QER, as borrower, entered into the third amended and restated credit agreement with RBC in the amount of approximately $43.8 million. In connection therewith, RBC, the lender under the PESC Loan released PESC from any liability or obligation to repay amounts owing under the PESC Loan and all of the guarantors thereunder from their respective guarantees of the indebtedness owing under the PESC Loan and (except for QER) from their respective mortgages and security agreements. RBC also released the liens on all the collateral owned by PESC, other than the Appalachian assets owned by QER and the equity of QER; and agreed to reconvey the overriding royalty interests to their respective grantors (or their designees) at such time as the Appalachian assets or equity of QER are sold. Accordingly, under the QER Loan, RBC has recourse only to QER, its assets and the equity of QER. See Note 2 in Part I, Item 1. of this Quarterly Report on Form 10-Q for a summary of the material terms of the QER Loan.
     As of October 30, 2010, the outstanding balance on the QER Loan was $43.8 million with no additional availability.
     In connection with the QER Loan, we entered into an asset sale agreement with RBC that allows us to sell QER or substantially all of its assets and, in the event the proceeds are not adequate to repay the QER Loan in full, we have agreed to pay a portion of such shortfall in cash, stock or a combination thereof. We currently believe that we will not be required to make any payments under the agreement to cover any shortfall.

Contractual Obligations
     We have numerous contractual commitments in the ordinary course of business, debt service requirements and operating lease commitments. Our commitments as of December 31, 2009, are disclosed within Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations” of our 2009 Form 10-K. In July 2010, we entered into an investment advisory agreement in conjunction with our efforts to sell certain oil and gas properties in Appalachia. The agreement does not require a minimum payment but instead specifies payment amounts that are contingent on the successful sale of the properties and amount of proceeds from such sale. Other than the preceding contract and the restructuring of our credit agreements described above, as of September 30, 2010, there were no other material changes to our commitments compared with December 31, 2009.
Off-Balance Sheet Arrangements
At September 30, 2010, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As such, we are not exposed to any financing, liquidity, market, or credit risk that could arise if we had engaged in such activities.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Commodity Price Risk
     Our most significant market risk relates to the prices we receive for our oil and natural gas production. In light of the historical volatility of these commodities, we periodically have entered into, and expect in the future to enter into, derivative arrangements aimed at reducing the variability of oil and natural gas prices we receive for our production.

Item 4. Controls and Procedures.
Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
     Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the principal executive officer and the principal financial officer, to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.
     In connection with the preparation of this Quarterly Report on Form 10-Q, our management, under the supervision and with the participation of the current principal executive officer and current principal financial officer, conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2010. While significant improvements have been implemented, we identified material weaknesses in our internal control over financial reporting, as discussed below, primarily due to the inability to sufficiently test newly implemented controls. As a result, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were not effective as of September 30, 2010. Notwithstanding this determination, our management believes that the condensed consolidated financial statements in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, and results of operations and cash flows as of the dates and for the periods presented, in conformity with GAAP.
     In connection with the preparation of our Annual Report on Form 10-K for the year ended December 31, 2009, our management, under the supervision and with the participation of our principal executive officer and principal financial officer at the time, conducted an evaluation of the effectiveness of our internal control over financial reporting as more fully disclosed in Item 9A(T) of the annual report.
     Based on the evaluation performed, we identified the following material weaknesses in our internal control over financial reporting as of December 31, 2009. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.
     (1) Control environment — We did not maintain a sufficient control environment. The control environment, which is the responsibility of senior management, sets the tone of the organization, influences the control consciousness of its people, and is the foundation for all other components of internal control over financial reporting. Specifically, during the first two quarters of 2009, management’s attention was focused on the restatement and reaudit of prior year financial statements and the recombination, which resulted in the full implementation of our remediation plan being delayed until the third quarter of 2009. During the first two quarters of 2009, only specific identified risks related to items such as the fraud hotline, segregation of duties and cash management controls were actively monitored.
     (2) Internal control over financial reporting — We did not maintain sufficient monitoring controls to determine the adequacy of our internal control over financial reporting. Specifically, we did not design and implement policies and procedures necessary to sufficiently determine and monitor the adequacy of our internal control over financial reporting.
     These material weaknesses relating to the overall control environment and monitoring of our internal control over financial reporting contributed to the material weaknesses described in items (3) through (6) below.
     (3) Period-end financial close and reporting — We did not maintain sufficient controls over certain of our period-end financial close and reporting processes. Specifically, we did not maintain controls over the preparation and review of the interim and annual consolidated financial statements to sufficiently ensure that we identified and accumulated all required supporting information to support the completeness and accuracy of the consolidated financial statements and that balances and disclosures reported in the consolidated financial statements reconciled to the underlying supporting schedules and accounting records.

15


Table of Contents

     (4) Stock compensation cost — We did not maintain sufficient controls to ensure completeness and accuracy of stock compensation costs. Specifically, controls did not operate sufficiently throughout the period to ensure that all stock transactions were properly communicated in order to be recorded accurately.
     (5) Depreciation, depletion and amortization — We did not maintain sufficient controls to ensure completeness and accuracy of depreciation, depletion and amortization expense. Specifically, controls did not operate sufficiently to appropriately calculate and review the depletion of oil and gas properties.
     (6) Impairment of oil and gas properties — We did not maintain sufficient controls to ensure the accuracy and application of GAAP related to the impairment of oil and gas properties and, specifically, to determine, review and record oil and gas property impairments.
     Each of the control deficiencies described in items (1) through (6) above could result in a misstatement of the aforementioned account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.
Changes in Internal Control Over Financial Reporting
     During 2009 and 2010, we implemented certain measures to improve our internal control over financial reporting and to remediate previously identified material weaknesses:
     (a) Appointed a new management team which, under the direction of the Board of Directors, was tasked with achieving and maintaining a strong control environment, high ethical standards, and financial reporting integrity. In May 2009, Mr. David Lawler was appointed Chief Executive Officer (our principal executive officer); in January 2010, Mr. Stephen DeGiusti was appointed General Counsel and Chief Compliance Officer, and in March 2010, Mr. Jack Collins was appointed Chief Financial Officer and Mr. David Klvac was appointed Chief Accounting Officer;
     (b) Hired additional experienced accounting personnel with specific experience in (1) financial reporting for public companies; (2) preparation of consolidated financial statements; (3) oil and gas property and pipeline asset accounting; (4) inter-company accounts and investments in subsidiaries; and (5) revenue accounting;
     (c) Implemented the practice of reviewing operating financial statements with members of our operations groups and consolidated financial statements with senior management, the audit committee of the board of directors, and the full board of directors;
     (d) Implemented a closing calendar and consolidation process that includes preparation of accrual-based financial statements, account reconciliations, inter-company accounts, and journal entries being reviewed by qualified personnel in a timely manner;
     (e) Engaged a professional services firm to assist with the evaluation of derivative transactions, and designed and implemented controls and procedures related to the evaluation and recording of derivative transactions;
     (f) Implemented additional training and/or increased supervision regarding the initiation, approval and reconciliation of cash transactions, and properly segregated the treasury and accounting functions related to cash management and wire transfers;
     (g) Engaged a professional services firm to assist with conducting the evaluation of the design and implementation of the internal control environment, and to assist with identifying opportunities to improve the design and effectiveness of the control environment;
     (h) Completed disclosure checklists for required disclosures under GAAP, SEC rules, and oil and gas accounting in an effort to ensure disclosures are complete in all material respects;
     (i) Created a disclosure committee as part of our SEC filing process and began regular meetings during the third quarter of 2009;

16


Table of Contents

     (j) Improved internal communication with employees regarding ethics and the availability of our internal fraud hotline; and
     (k) Performed a preliminary assessment of accounting and disclosure policies and procedures and began the process of updating and revising those policies and procedures.
     (l) Created a steering committee to monitor the progress of the evaluation of the internal controls and began regular meetings during the second quarter of 2010.
     (m) Created a policy aimed at standardizing the form, timing and authorization of stock based awards.
     We believe these measures have strengthened our internal control over financial reporting and disclosure controls and procedures and have effectively remediated our remaining control deficiencies for future reporting periods. We are unable to conclude that the material weaknesses identified above have been remediated, however, because the measures we have implemented have not yet been fully tested.
     Our new leadership team, together with other senior executives and our Board of Directors, is committed to achieving and maintaining a strong control environment, high ethical standards, and financial reporting integrity. This commitment has been and will continue to be communicated to and reinforced with our employees and to external stakeholders.
     In addition, under the direction of the Board of Directors, management will continue to review and make changes to the overall design of our internal control environment, as well as policies and procedures to improve the overall effectiveness of internal control over financial reporting and our disclosure controls and procedures.
     Other than the measures discussed above, there were no changes in our internal control over financial reporting that occurred during the third quarter of 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
     In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, was enacted into law. The Dodd-Frank Act provides smaller public companies and debt-only issuers with a permanent exemption from the requirement to obtain an external audit on the effectiveness of internal financial reporting controls provided in Section 404(b) of the Sarbanes-Oxley Act. PostRock is a non-accelerated filer and is eligible for this exemption under the Dodd-Frank Act. PostRock will still be required to disclose management’s assessment of the effectiveness of internal control over financial reporting under existing Section 404(a) of the Sarbanes-Oxley Act. The amendment to the Sarbanes-Oxley Act was effective immediately.

Item 1A. Risk Factors.
     For additional information about our risk factors, see Item 1A. “Risk Factors” in our 2009 Form 10-K.
White Deer Energy L.P. and its affiliates beneficially own approximately 69% of our common stock on a fully diluted basis, giving White Deer influence and control in corporate transactions and other matters, including a sale of our company.
     As of November 7, 2010, White Deer Energy L.P. and its affiliates beneficially own 19,047,619 shares of our common stock, issuable upon exercise of outstanding warrants, representing approximately 69% of the shares on a fully diluted basis. In addition, we have agreed to issue White Deer additional warrants on each quarterly dividend payment date of the Series A Preferred Stock prior to July 1, 2013 on which dividends are not paid in cash but instead accrue. Until December 31, 2011, White Deer, as the holder of the Series B Preferred Stock issued with the warrants, is limited to 45% of the votes applicable to all outstanding voting stock, which limit includes any common stock held by White Deer. After December 31, 2011, the limit only restricts the voting of the Series B Preferred Stock, and White Deer may vote any shares of common stock held by it without regard to that limit.
     As a result of its ownership, White Deer effectively will be our controlling stockholder and able to control the election of our directors, determine our corporate and management policies and determine, without the consent of our other stockholders, the outcome of certain corporate transactions or other matters submitted to our stockholders for approval, including, for example, potential mergers or acquisitions, asset sales and other significant corporate transactions. The interests of White Deer may not coincide with the interests of other holders of our common stock.
     Subject to certain restrictions, White Deer may make investments in companies that compete with us. In addition, our interests may conflict with those of White Deer with respect to, among other things, business opportunities that may be presented to White Deer and to our directors associated with White Deer.
Substantial sales of our common stock by White Deer could cause our stock price to decline.
     We are unable to predict whether significant amounts of our common stock will be sold by White Deer. Any sales of substantial amounts of our common stock in the public market by White Deer, or the perception that these sales might occur, could lower the market price of our common stock. In addition, White Deer generally is not prohibited from selling their interest in us to a third party.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Item 5. Other Information.
     On September 1, 2010, our Board of Directors approved the form of indemnification agreement for our directors and executive officers and authorized us to enter into such an agreement with each of our directors and executive officers. We have since entered into an indemnification agreement with each of our directors and executive officers, including the three director designees of White Deer. The agreement provides, among other things, for rights to indemnification to the fullest extent authorized by the Delaware law and the advancement of expenses in connection with service as one of our directors or officers or, at our request, as a director, officer, employee, trustee or other legal representative of any other corporate entity or employee benefit plan. The agreement is in addition to any other rights the director or officer, as applicable, may be entitled to under our bylaws or Delaware law.
