Note 1—Business Organization PostRock Energy Corporation (“PostRock”) was formed in 2009 to combine its predecessor entities, Quest Resource Corporation (“QRCP”), Quest Energy Partners, L.P. (“QELP”) and Quest Midstream Partners, L.P. (“QMLP”) (collectively, the “Predecessors”) into a single entity. On March 6, 2010, PostRock completed the recombination of these entities (the “Recombination”). Unless the context requires otherwise, references to the “Company,” “we,” “us” and “our” refer to PostRock and its subsidiaries from the date of the Recombination and to the Predecessors on a consolidated basis prior thereto. The Company is an independent oil and gas company engaged in the acquisition, exploration, development, production and gathering of crude oil and natural gas. It manages its business in two segments, production and pipeline. Its production segment is focused in the Cherokee Basin, a 15-county region in southeastern Kansas and northeastern Oklahoma. It also has minor oil producing properties in Oklahoma and oil and gas producing properties in the Appalachian Basin. The pipeline segment consists of a 1,120 mile interstate natural gas pipeline, which transports natural gas from northern Oklahoma and western Kansas to Wichita and Kansas City (the “KPC Pipeline”).

Note 2—Summary of Significant Accounting Policies Principles of Consolidation—These consolidated financial statements include the Company’s and its subsidiaries’ accounts. Subsidiaries in which the Company directly or indirectly owns more than 50% of the outstanding voting securities or those in which the Company has effective control over are generally accounted for under the consolidation method of accounting. Under this method, a subsidiaries’ balance sheet and results of operations are reflected within the Company’s consolidated financial statements. The equity of the noncontrolling interests in the Company’s majority-owned or effectively controlled subsidiaries are shown in the consolidated financial statements as “noncontrolling interest”. Noncontrolling interest adjusts the consolidated results of operations to reflect only the Company’s share of the earnings or losses of the consolidated subsidiary. Upon dilution of control below 50% or the loss of effective control, the accounting method is adjusted to the equity or cost method of accounting, as appropriate, for subsequent periods. All significant intercompany accounts and transactions have been eliminated. Use of Estimates in the Preparation of Financial Statements—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s most significant recurring estimates are based on remaining proved oil and gas reserves. Estimates of proved reserves are key components of the Company’s depletion rate for oil and gas properties and its full cost ceiling test limitation. In addition, estimates are used in computing fair value of impaired assets, taxes, asset retirement obligations, fair value of derivative contracts and other items. Actual results could differ from these estimates. Cash and Cash Equivalents—The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash balances are maintained at several financial institutions that are insured by the Federal Deposit Insurance Corporation although such balances typically are in excess of the insured amount; however, no losses have been recognized as a result of this circumstance. During 2011, the Company began utilizing a controlled disbursement cash account which is funded when outstanding checks and electronic payments are presented for payment and an overdraft is the normal book balance. The Company’s policy has been to fund these outstanding checks and electronic payments as they clear through the banking system with customer receipts and borrowings under its Borrowing Base Credit Facility (as defined below). The Company accounts for such outstanding checks and electronic payments that have been issued but not cleared through the banking system by reporting them in accounts payable in its consolidated balance sheets and including the change in such amounts in cash flows from operating activities in its consolidated statements of cash flows. Outstanding checks and electronic payments included in accounts payable at December 31, 2011, amounted to $2.1 million. Accounts Receivable—The Company conducts the majority of its operations in Kansas and Oklahoma and operates exclusively in the oil and gas industry. Receivables are generally unsecured; however, the Company has not experienced any significant losses to date. Receivables are recorded at the estimate of amounts due based upon the terms of the related agreements. Management periodically assesses the accounts receivable and establishes an allowance for estimated uncollectible amounts. Accounts estimated to be uncollectible are charged to operations in the period the reserve is established. The allowance for doubtful accounts was approximately $258,000 and $181,000 at December 31, 2010 and 2011, respectively. Inventory—Inventory includes tubular goods and other lease and well equipment which the Company plans to utilize in its ongoing exploration and development activities and is carried at the lower of cost or market using the specific identification method. Oil and Natural Gas Properties—The Company uses the full cost method of accounting for oil and gas properties. Under the full cost method, all direct costs and certain indirect costs associated with the acquisition, exploration, and development of its oil and gas properties are capitalized. Oil and gas properties are depleted using the units-of-production method. The depletion expense is significantly affected by the unamortized historical and future development costs and the estimated proved oil and gas reserves. Estimation of proved oil and gas reserves relies on professional judgment and use of factors that cannot be precisely determined. Holding all other factors constant, if proved oil and gas reserve quantities were revised upward or downward, earnings would increase or decrease, respectively. Subsequent proved reserve estimates materially different from those reported would change the depletion expense recognized during the future reporting period. No gains or losses are recognized upon the sale or disposition of oil and gas properties unless the deferral of gains or losses will result in an amortization rate materially different from the amortization rate calculated upon recognition of gains or losses. Under the full cost accounting rules, total capitalized costs are limited to a ceiling equal to the present value of future net revenues, discounted at 10% per annum less income tax effects (the “ceiling limitation”). The Company performs a quarterly ceiling test to evaluate whether the net book value of its full cost pool exceeds the ceiling limitation. If capitalized costs (net of accumulated depreciation, depletion, and amortization) less related deferred taxes are greater than the discounted future net revenues or ceiling limitation, a write-down or impairment of the full cost pool is required. A write-down of the carrying value of the full cost pool is a non-cash charge that reduces earnings and impacts stockholders’ (deficit) equity in the period of occurrence and typically results in lower depreciation, depletion, and amortization expense in future periods. Once incurred, a write-down is not reversible at a later date. The risk that the Company will be required to write down the carrying value of its oil and gas properties increases when oil and gas prices are depressed, even if low prices are temporary. This is partially mitigated by recent changes in accounting rules requiring the use of an unweighted arithmetic first day of the month price for trailing average twelve-month market prices to determine the ceiling. In addition, a write-down may occur if estimates of proved reserves are substantially reduced or estimates of future development costs increase significantly. Unevaluated Properties—The costs directly associated with unevaluated oil and gas properties and properties under development are not initially included in the amortization base and relate to unproved leasehold acreage, seismic data, wells and production facilities in progress and wells pending determination together with interest costs capitalized for these projects. Unevaluated leasehold costs are transferred to the amortization base once determination has been made or upon expiration of a lease. Geological and geophysical costs and cumulative drilling costs to date associated with a specific unevaluated property are transferred to the amortization base with the associated leasehold costs on a specific project basis. Costs associated with wells in progress and wells pending determination are transferred to the amortization base once a determination is made whether or not proved reserves can be assigned to the property. All items included in the Company’s unevaluated property balance are assessed on a quarterly basis for possible impairment or reduction in value. The assessment includes consideration of numerous factors, including intent to drill, remaining lease term, geological and geophysical evaluations, drilling results and activity, assignment of proved reserves and economic viability of development if proved reserves are assigned. Any impairments of unevaluated properties are transferred to the amortization base. Capitalized General and Administrative Expenses—Under the full cost method of accounting, a portion of general and administrative expenses that are directly attributable to acquisition, exploration, and development activities are capitalized to the full cost pool. The capitalized costs include salaries, related fringe benefits, cost of consulting services and other costs directly associated with those activities. The Company capitalized general and administrative costs of $843,000 related to its acquisition, exploration and development activities for the period from March 6 to December 31, 2010 and $1.1 million for the year ended December 31, 2011. It did not capitalize any general and administrative expenses in 2009 due to the significant decrease in its acquisition and development activities. Capitalized Interest Costs—The Company capitalizes interest based on the cost of major development projects. Capitalized interest was $51,000 for the year ended December 31, 2011, while no interest was capitalized for the years ended December 31, 2009 and 2010. Other Property and Equipment—The cost of other property and equipment is depreciated over the estimated useful lives of the related assets. The cost of leasehold improvements is depreciated over the lesser of the length of the related leases or the estimated useful lives of the assets. Upon disposition or retirement of property and equipment, other than oil and gas properties, the cost and related accumulated depreciation are removed from the accounts and the gain or loss thereon, if any, is recognized in the statement of operations in the period of sale or disposition. Maintenance and repair costs are charged to operating expense as incurred. Impairment—Long-lived assets, such as property, equipment, and finite-lived intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of such assets to estimated undiscounted future cash flows expected to be generated by the assets. If the carrying amount of such assets exceeds their undiscounted estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of such assets exceeds the fair value of the assets. Intangible Assets—The Company carries contract-related intangible assets that were obtained in connection with the KPC Pipeline acquisition; they are amortized over their estimated useful lives and are reviewed for impairment whenever impairment indicators are present. Equity Investment—The Company elected to measure its investment in Constellation Energy Partners LLC (“CEP”) at fair value with changes in fair value included in the consolidated statement of operations. If the Company had not elected the fair value method, the investment would have qualified for the equity method of accounting, under which the Company’s proportionate share of the investee’s income would have been reported in the consolidated statement of operations.   Asset Retirement Obligations—Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 410, Asset Retirement and Environmental Obligations (ASC 410) requires that the fair value of an asset retirement cost and the corresponding liability should be recorded as part of the cost of the related long-lived asset and subsequently allocated to expense using a systematic and rational method. The Company records asset retirement obligations to reflect the Company’s legal obligations related to future plugging and abandonment of its natural gas and oil wells and interstate pipeline assets. Asset retirement obligations associated with the retirement of a tangible long-lived asset are recognized as a liability in the period incurred or when it becomes determinable that there is a legal or contractual obligation to dismantle or dispose of the asset and reclaim or remediate any related property at the end of its useful life, with an associated increase in the carrying amount of the related long-lived asset. The cost of the tangible asset, including the asset retirement cost, is depreciated over the useful life of the asset. The asset retirement obligation is recorded at its estimated fair value, measured by reference to the expected future cash outflows required to satisfy the retirement obligation discounted at the Company’s credit-adjusted risk-free interest rate. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. If the estimated future cost of the asset retirement obligation changes, an adjustment is recorded to both the asset retirement obligation and the long-lived asset. Revisions to estimated asset retirement obligations can result from changes in retirement cost estimates, revisions to estimated inflation rates and changes in the estimated timing of abandonment. The Company owns oil and gas properties that require expenditures to plug and abandon the wells when the oil and gas reserves in the wells are depleted. These expenditures are recorded in the period in which the liability is incurred (at the time the wells are drilled or acquired). Asset retirement obligations are recorded as a liability at their estimated present value at the asset’s inception, with the offsetting increase to property cost. Periodic accretion expense of the estimated liability is recorded in the consolidated statements of operations. The Company has recorded asset retirement obligations relative to the abandonment of its interstate pipeline assets because the Company believes it has a legal or constructive obligation relative to asset retirements of the interstate pipeline system. It has not recorded an asset retirement obligation relating to its gathering system because it does not have any legal or constructive obligations relative to asset retirements of the gathering system. Derivative Instruments—The Company utilizes derivative instruments in conjunction with marketing and trading activities to manage price risk attributable to its forecasted sales of oil and gas production. The Company elects “Normal Purchases Normal Sales” (“NPNS”) accounting for derivative contracts that provide for the purchase or sale of a physical commodity that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Derivatives that are designated as NPNS are accounted for under the accrual method of accounting. For those derivatives that do not meet the requirements for NPNS designation nor qualify for hedge accounting, the Company believes that such contracts are still effective as economic hedges of its commodity price exposure. These contracts are accounted for using the mark-to-market accounting method. Using this method, the contracts are carried at their fair value on the Company’s consolidated balance sheets under the caption “Derivative financial instruments.” The Company recognizes all unrealized and realized gains and losses related to these contracts on its consolidated statements of operations under the caption “Gain (loss) from derivative financial instruments,” which is a component of other income (expense). The Company has exposure to credit risk to the extent a counterparty to a derivative instrument is unable to meet its settlement commitment. It actively monitors the creditworthiness of each counterparty and assesses the impact, if any, on its derivative positions. The Company does not apply hedge accounting to its derivative instruments. As a result, both realized and unrealized gains and losses on derivative instruments are recognized in the statement of operations as they occur. Legal—The Company is subject to legal proceedings, claims and liabilities which arise in the ordinary course of its business. It accrues for losses associated with legal claims when such losses are probable and can be reasonably estimated. These estimates are adjusted as additional information becomes available or circumstances change. Revenue Recognition—Revenue from the Company’s oil and gas operations is derived from the sale of produced oil and natural gas. The Company uses the sales method of accounting for the recognition of oil and gas revenue. Because there is a ready market for oil and gas, the Company sells its oil and gas shortly after production at various pipeline receipt points at which time title and risk of loss transfers to the buyer. Revenue is recorded when title and risk of loss is transferred based on the Company’s net revenue interests. Gathering revenue is recognized at the time the gas is gathered or transported through the system and delivered to a third party as evidenced by a contract. Transportation revenue from the Company’s interstate pipeline operations is primarily from services pursuant to firm transportation agreements. These agreements provide for a demand charge based on the volume of contracted capacity and a commodity charge based on the volume of gas delivered, both at rates specified in the Company’s Federal Energy Regulatory Commission (“FERC”) tariffs. The Company recognizes revenues from demand charges ratably over the contract period regardless of the volume of gas that is transported or stored. Revenues for commodity charges are recognized when gas is scheduled to be delivered at the agreed upon delivery point. Environmental Costs—Environmental expenditures are expensed or capitalized, as appropriate, depending on future economic benefit. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefit are expensed. Liabilities related to future costs are recorded on an undiscounted basis when environmental assessments and/or remediation activities are probable and costs can be reasonably estimated. The Company has no environmental costs accrued for the periods presented. Stock-Based Compensation—The Company grants various types of stock-based awards (including stock options and restricted stock) and accounts for stock-based compensation at fair value. The fair value of stock option awards is determined using a Black-Scholes pricing model. The fair value of restricted stock awards are valued using the market price of the Company’s common stock on the grant date. Stock-based compensation expense is recognized over the requisite service period net of estimated forfeitures. The Company accounts for stock-based compensation in accordance with FASB ASC 718 Compensation—Stock Compensation, which requires that compensation related to all stock-based awards, including stock options, be recognized in the financial statements based on their estimated grant-date fair value. Income Taxes—The Company records its income taxes using an asset and liability approach in accordance with the provisions of the FASB ASC 740 Income Taxes. This results in the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences (primarily intangible drilling costs and the net operating loss carry forward) between the book carrying amounts and the tax bases of assets and liabilities using enacted tax rates at the end of the period. Under FASB ASC 740, the effect of a change in tax rates of deferred tax assets and liabilities is recognized in the year of the enacted change. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. At December 31, 2010 and 2011, a full valuation allowance was recorded against the Company’s net deferred tax assets.   The Company regularly analyzes tax positions taken or expected to be taken in a tax return based on the threshold condition prescribed under FASB ASC 740. Tax positions that do not meet or exceed this threshold condition are considered uncertain tax positions. The Company accrues interest and penalties related to uncertain tax positions as income tax expense. Net Income (Loss) per Common Share—Basic earnings (loss) per share is calculated by dividing net income (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share assumes the conversion of all potentially dilutive securities (warrants, stock options and restricted stock awards) and is calculated by dividing net income (loss) by the sum of the weighted average number of shares of common stock outstanding plus potentially dilutive securities under the treasury stock method. Concentrations of Market Risk—The Company’s future results will be affected by the market price of oil and gas. The availability of a ready market for oil and gas will depend on numerous factors beyond the Company’s control, including weather, production of oil and gas, imports, marketing, competitive fuels, proximity of oil and gas pipelines and other transportation facilities, any oversupply or undersupply of oil and gas, the regulatory environment, and other regional and political events, none of which can be predicted with certainty. Concentrations of Credit Risk—Financial instruments, which subject the Company to concentrations of credit risk, consist primarily of cash and accounts receivable. Risk with respect to receivables at December 31, 2010 and 2011, arise substantially from the sales of oil and gas and transportation revenue from its pipeline system. ONEOK Energy Marketing and Trading Company (“ONEOK”) accounted for 81%, 60% and 31% of oil and gas revenue for the years ended December 31, 2009, 2010 and 2011, respectively. Fair Value—The Company adopted the full provisions of FASB ASC 820 Fair Value Measurements and Disclosures effective January 1, 2009. Fair value is the exit price that we 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:   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="5%"> </td> <td width="2%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> Level 1—Quoted prices available in active markets for identical assets or liabilities at the reporting date. </td> </tr> </table>   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="5%"> </td> <td width="2%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> Level 2—Pricing inputs other than quoted prices in active markets included in Level 1 which are either directly or indirectly observable at the reporting date. Level 2 consists primarily of non-exchange traded commodity derivatives. </td> </tr> </table>   <table style="border-collapse:collapse; text-align: left" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="5%"> </td> <td width="2%" valign="top" align="left">•</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> Level 3—Pricing inputs include significant inputs that are generally less observable from objective sources. </td> </tr> </table> 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 may be 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 income valuation approach, which involves discounting estimated cash flows, is primarily used to determine recurring fair value measurements of the Company’s derivative instruments classified as Level 2 or Level 3. Transfers of assets and liabilities between Level 1 and Level 2 are recognized at the end of a reporting period. The Company prioritizes the use of the highest level inputs available in determining fair value.   The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of assets and liabilities within the fair value hierarchy. Because of the long-term nature of certain assets and liabilities measured at fair value as well as differences in the availability of market prices and market liquidity over their terms, inputs for some assets and liabilities may fall into any one of the three levels in the fair value hierarchy. While FASB ASC 820 requires classification of these assets and liabilities in the lowest level in the hierarchy for which inputs are significant to the fair value measurement, a portion of that measurement may be determined using inputs from a higher level in the hierarchy. Recent Accounting Pronouncements In January 2010, the FASB issued 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 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 is 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, while the provisions requiring gross presentation of activity within Level 3 assets were adopted beginning with the quarter ended March 31, 2011. The adoption did not materially affect the Company’s financial statements. In May 2011, the FASB issued ASU 2011-04 Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. ASU 2011-04 clarifies the principles and definitions used to measure fair value and expands disclosure requirements in order to achieve greater consistency between U.S. GAAP and International Financial Reporting Standards. The amendment does not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financial reporting. ASU 2011-04 is to be applied prospectively and is effective during interim and annual periods beginning after December 15, 2011. The amendment will not have a material impact on the Company’s financial statements. In June 2011, the FASB issued ASU 2011-05 Comprehensive Income (Topic 220): Presentation of Comprehensive Income. ASU 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income and the total of comprehensive income. Certain provisions in this update relating to the new presentation for reclassifications of items out of accumulated other comprehensive income have been delayed indefinitely. The remaining amendments are to be applied retrospectively and are effective for fiscal years and interim periods within those years beginning after December 15, 2011. The amendment will not have a material impact on the Company’s financial statements.

Note 3—Acquisitions and Divestitures CEP Investment—During 2011, the Company acquired from Constellation Energy Group, Inc. (“CEG”) a 26.4% voting interest in CEP in two separate transactions at a total cost of $17.6 million. In the first transaction, the Company acquired a 14.9% voting interest in CEP which included the right to appoint two directors to CEP’s Board. The 14.9% voting interest consisted of 485,065 of CEP’s outstanding Class A Member Interests, representing all of the class, and 3,128,670 Class B Member Interests. In the second transaction, the Company acquired an additional 2,790,224 Class B Member Interests, bringing the Company’s ownership to a combined 26.4% voting interest at December 31, 2011. The $17.6 million cost included $12.6 million of cash, 1,000,000 shares of the Company’s common stock with a fair value of $4.1 million, warrants to acquire an additional 673,822 shares of the Company’s common stock with a fair value of $518,000, and acquisition costs of $352,000. Of the warrants, 224,607 are exercisable for one year following issuance at an exercise price of $6.57 a share, 224,607 are exercisable for two years following issuance at $7.07 a share and 224,608 for three years following issuance at $7.57 a share. The Class B Member Interests are traded on the New York Stock Exchange under the ticker symbol “CEP” with a closing price of $1.96 per unit at December 30, 2011. CEP is focused on the acquisition, development and production of oil and natural gas properties as well as related midstream assets. All of its proved reserves are located in the Cherokee Basin in Kansas and Oklahoma, the Black Warrior Basin in Alabama, the Woodford Shale in the Arkoma Basin in Oklahoma and the Central Kansas Uplift in Kansas and Nebraska. Because PostRock and CEP each have the majority of their assets in the Cherokee Basin of Kansas and Oklahoma, the investment was made in an attempt to work with CEP to explore opportunities to reduce costs and enhance value for the companies’ respective investors. Appalachia Basin Sale—On December 24, 2010, the Company entered into an agreement with Magnum Hunter Resources Corporation (“MHR”) to sell certain oil and gas properties and related assets in West Virginia. The sale closed in three phases for a total of $44.6 million. The first phase closed in December 2010 for $28 million while the following two phases closed in January and June 2011 for a combined $16.6 million. The amount received for the first and second phases was paid half in cash and half in MHR common stock, while the amount received for the third phase was paid entirely in cash. Of the proceeds received, $6.4 million was set aside in escrow to cover potential claims for indemnity and title defects. The total first and second closing escrowed amount of $5.9 million is to be released in June 2012 while the third closing escrowed amount of $564,000 is to be released in December 2012. These amounts are reflected in the consolidated balance sheet as a component of other current assets. If all of the amounts in escrow are released, the Company would receive a total of $1.5 million, which includes $843,000 in connection with the QER Loan (see Note 10—Long-Term Debt). The remaining amount would be released to the lender and a third-party and is reflected in the consolidated balance sheet in other current liabilities. In general, no gains or losses are recognized upon the sale or disposition of oil and gas properties unless the deferral of gains or losses would significantly alter the relationship between capitalized costs and proved reserves of oil and gas. A significant alteration generally occurs when the deferral of gains or losses will result in an amortization rate materially different from the amortization rate calculated upon recognition of gains or losses. The Company’s evaluation demonstrated that a material difference in amortization rates would occur if no gain was recognized on the three-phased sale described above. Gains of $13.7 million and $12.5 million, net of $728,000, and $2.6 million in selling costs and adjustments, were recorded in 2010 and 2011 related to the three phases of the sale. The corresponding reduction in the Company’s oil and gas full cost pool for the three phases of the sale was $13.6 million and $1.5 million in 2010 and 2011, respectively. On February 13, 2009, the Company divested approximately 23,000 net undeveloped acres and one well in Lycoming County, Pennsylvania to a private party for approximately $8.7 million. The proceeds from the divestiture during 2009 reduced the full cost pool.     Note 4—Other Balance Sheet Items The following describes the components of the following consolidated balance sheet items

Projected amortization expense is expected to be $292,000 in 2012, $250,000 in 2013 and $134,000 thereafter. Amortization expense related to those contracts was $3.3 million for the year ended December 31, 2009. Amortization for the periods from January 1 to March 5, 2010, and from March 6 to December 1, 2010, was $78,000 and $214,000, respectively. Amortization expense related to those contracts for the year ended December 31, 2011 was $292,000. As discussed in Note 5, the Company recorded an impairment of its KPC pipeline during the fourth quarter of 2009 upon the loss of a contract with a major customer. The impairment analysis included the contract-related intangibles as part of the asset grouping for which the lowest level of independent cash flows could be identified apart from cash flows attributable to other assets and liabilities of the Company’s pipeline segment. Upon determining the write-off required for the asset group, the Company allocated a pro-rata portion of the write-off to the contract related intangibles of $1.0 million. The write-off is reflected as a component of impairments in the consolidated statement of operations for the year ended December 31, 2009. Deferred Financing Costs—The Company’s expense related to amortizing or writing off deferred financing costs was $7.8 million for the year ended December 31, 2009, $2.1 million and $5.7 million for the periods from January 1 to March 5 and from March 6 to December 31, 2010, respectively, and $1.7 million for the year ended December 31, 2011. These costs are included in interest expense. Included in the amounts above were $3.5 million and $1.8 million of write-offs of unamortized debt issuance costs for the year ended December 31, 2009, and for the period from March 6 to December 31, 2010, respectively. The write-offs were made in connection with substantial amendments of the Company’s credit facilities during those periods.

</table> For the year ended December 31, 2009, depletion, depreciation and amortization expense (excluding impairment amounts discussed below) on oil and gas properties amounted to $35.5 million; depreciation expense on pipeline assets amounted to $5.0 million and depreciation expense on other property and equipment amounted to $3.5 million. For the periods from January 1 to March 5, 2010, and from March 6 to December 31, 2010, depletion, depreciation and amortization expense on oil and gas properties amounted to $2.9 million and $12.0 million, respectively; depreciation expense on pipeline assets amounted to $496,000 and $2.5 million, respectively; and depreciation expense on other property and equipment amounted to $604,000 and $3.4 million, respectively. For the year ended December 31, 2011, depletion, depreciation and amortization expense on oil and gas properties amounted to $19.6 million; depreciation expense on pipeline assets amounted to $3.0 million; and depreciation expense on other property and equipment amounted to $4.1 million. During 2011, the Company elected to shorten the depreciable lives of selected vehicle and equipment property in its pipeline segment as well as technologically limited assets, including computer hardware and communication devices, in service throughout the Company. The overall impact of this change was to increase depletion, depreciation and amortization by $0.7 million and aligns the remaining depreciable lives for these assets along the lines of the demonstrated useful lives of these assets.   Impairment of oil and gas properties—At December 31, 2011, the Company’s net book value of oil and gas properties was below the full cost ceiling. Accordingly, a provision for impairment was not required in the fourth quarter of 2011 while no impairment was recorded during the prior quarters of 2011. The Company recorded impairments of $102.9 million for the year ended December 31, 2009, while no impairment was recorded for the year ended December 31, 2010. During the fourth quarter of 2010, the Company reclassified the operations and assets of its gathering system in the Cherokee Basin from its former natural gas pipelines segment to its production segment. The gathering system was subject to an impairment charge of $112.2 million during the fourth quarter of 2009. The impairment was due to a reduction in projected future gathering revenues associated with the Company’s Cherokee Basin production partially the result of the capital expenditure limits contained in the Company’s former credit facilities. Impairment of pipeline related assets—During the fourth quarter of 2009, the Company recorded an impairment of $52.6 million on its pipeline assets and $1.0 million on the related contract-intangibles. The impairment was triggered by the Company’s inability to negotiate a new contract with one of its major customers, Missouri Gas and Electric (“MGE”). Its existing contract with MGE expired in October 2009, although prior to the expiration the Company believed that the contract could be extended or renegotiated with MGE or replaced by another customer.

Note 6—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. 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. Specifically, the Company may utilize futures, swaps and options. Derivative instruments expose the Company to counterparty credit risk. The Company’s commodity derivative instruments are currently with several counterparties. The Company generally executes commodity derivative instruments under master agreements which allow it, in the event of default, to elect early termination of all contracts with the defaulting counterparty. If the Company chooses to elect early termination, all asset and liability positions with the defaulting counterparty would be net cash settled at the time of election. The Company monitors the creditworthiness of its counterparties; however, it is not able to predict sudden changes in counterparties’ creditworthiness. In addition, even if such changes are not sudden, it may be limited in its ability to mitigate an increase in counterparty credit risk. Possible actions would be to transfer its position to another counterparty or request a voluntary termination of the derivative contracts resulting in a cash settlement. Should one of these counterparties not perform, the Company may not realize the benefit of some of its derivative instruments under lower commodity prices as well as incur a loss. The Company includes a measure of counterparty credit risk in its estimates of the fair values of derivative instruments in an asset position.   The Company does not designate its derivative financial instruments as hedging instruments for financial accounting purposes; as a result, it recognizes the change in the respective instruments’ fair value currently in earnings. The tables below outline the classification of derivative financial instruments on the consolidated balance sheet and their financial impact on the consolidated statements of operations at and for the

Note 7—Financial Instruments The Company’s financial instruments include commodity derivatives, debt, cash, receivables, payables, redeemable preferred stock and equity securities. The carrying amount of cash, receivables and payables approximates fair value because of the short-term nature of those instruments. 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. In June 2011, the Company transferred 23,517 shares of MHR common stock with a fair value of $159,000 from Level 2 to Level 1 due to the limited amount of time remaining until restrictions on the Company’s ability to trade these securities lapsed in July 2011. The lifting of restrictions enabled the Company to value these securities at published market prices. Following the lapse of restrictions, these securities were sold in July 2011 for approximately $168,000. There were no other movements between Levels 1 and 2 during the periods from January 1 to March 5 and March 6 to December 31, 2010, and for the year ended December 31, 2011.   The following table sets forth a reconciliation of changes in the fair value of risk management assets and liabilities classified as Level 3 in the fair value hierarchy for the periods presented (in thousands). There were no purchases, sales or issuances during the time period presented.   <table cellspacing="0" cellpadding="0" width="92%" border="0" style="border-collapse:collapse; text-align: left"

consist of variable to fixed price swaps, collars and basis swaps. When possible, the Company estimates the fair values of these instruments based on published forward commodity price curves as of the date of the estimate. The discount rate used in the discounted cash flow projections is based on published LIBOR rates adjusted for counterparty credit risk. Counterparty credit risk is incorporated into derivative assets while the Company’s own credit risk is incorporated into derivative liabilities. Both are based on the current published credit default swap rates. Short-Term Investments At December 31, 2010, these investments consisted of 218,095 shares of MHR common stock received as proceeds from the Appalachia Basin sale described in Note 3, which were subsequently sold in June 2011 for $1.5 million. The fair value of these securities at December 31, 2010, was based on the published market price of the common stock adjusted for a six month restriction on the Company’s ability to trade the securities at that time.   Equity Investment The Company’s 26.4% voting interest in CEP at December 31, 2011, consists of 485,033 of CEP’s outstanding Class A Member Interests and 5,918,894 Class B Member Interests. Fair value for the Class B Member Interests, which are publicly traded, is based on market price. Fair value for the Class A Member Interests is based on the market price of the publicly traded interests and a premium reflecting certain additional rights. At December 31, 2011, the fair values used for the Class A units and the Class B units were $2.87 and $1.96 per unit, respectively. Additional Fair Value Disclosures—The Company has 6,000 outstanding shares of Series A Cumulative Redeemable Preferred Stock (see Note 12—Redeemable Preferred Stock). The fair value and the carrying value of these securities at December 31, 2010, were $68.5 million and $50.6 million, respectively. The fair value and the carrying value of these securities at December 31, 2011, were $62.2 million and $56.7 million, respectively. The fair value was determined by discounting the cash flows over the remaining life of the securities utilizing a LIBOR interest rate and a risk premium of approximately 13.0% at December 31, 2011, which was based on companies with similar leverage ratios to PostRock. The Company’s long term debt consists entirely of floating-rate facilities. The carrying amount of floating-rate debt approximates fair value because the interest rates paid on such debt are generally set for periods of six months or shorter.

Note 8—Equity Investment The Company believes that its 26.4% voting interest in CEP at December 31, 2011, along with the right to appoint two directors to CEP’s Board provide it the ability to exercise significant influence over the operating and financial policies of CEP. Rather than accounting for the investment under the equity method, the Company elected the fair value option to account for its interest in CEP at the first acquisition date on August 8, 2011. The fair value option was chosen as the Company determined that the market price of CEP’s publicly traded interests provided a more accurate fair value measure of the Company’s investment in CEP. The Company has not elected the fair value option for any of its other assets and liabilities. As a result of the decline in the market price of CEP’s traded interests, the Company recorded a loss of $4.6 million for the year ended December 31, 2011. The loss was recorded as a component of other income (expense) in the consolidated statement of operations.

obligation to plug, abandon and dismantle 30 inactive wells in the Cherokee Basin. The actual costs associated with these retirements were used to review and revise the Company’s current asset retirement obligation estimates. In reviewing current estimates against actual costs incurred in 2011, the Company increased its reserve amount by $3.9 million. The increase was primarily due to an increase in labor and third party costs required to perform the necessary remediation.

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 December 31, 2011, was 4.57%. Maturity Date June 30, 2013. Borrowing Base Redetermination The first borrowing base redetermination with respect to the indebtedness under the Borrowing Base Facility was made on July 31, 2011, based on the Company’s March 31, 2011, oil and gas reserves. The borrowing base is determined based on the value of reserves at the Company’s lenders’ forward price forecasts, which are generally derived from futures prices. As a result of the significant decline in lender forward price forecasts since the Company’s prior borrowing base determination and the roll off of hedges, the borrowing base was reduced from $225 million to $200 million. 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. The Company was in compliance with all its financial covenants under the Secured Pipeline Loan at December 31, 2011. The Company repaid the outstanding balance on the Secured Pipeline Loan in full on its maturity date of February 28, 2012. QER Loan In connection with the restructuring of the Company’s credit facilities in 2010, the Company entered into an asset sale agreement with RBC that allowed the Company to sell PostRock Eastern Production, LLC, formerly named Quest Eastern Resource LLC (“QER”), or its assets and, in the event the proceeds were not adequate to repay the QER Loan in full, the Company agreed to pay a portion of such shortfall in cash, stock or a combination thereof. As discussed in Note 3, the Company sold certain Appalachian Basin oil and gas properties to MHR in three phases that closed in December 2010, January 2011 and June 2011. Included in the $44.6 million total was approximately $41.6 million representing the purchase price of assets owned by QER pledged as collateral under the QER Loan. From the sale proceeds, QER made payments to the lender, RBC, in the amount of $21.2 million in December 2010, $9.3 million in January 2011 and $4.3 million in June 2011. The $9.3 million payment in January 2011 consisted of $5.7 million in MHR common stock and $3.6 million in cash while the $4.3 million payment in June 2011 was entirely in cash. Concurrent with the June 2011 payment and pursuant to the terms of an asset sale agreement with RBC, the Company fully settled the outstanding balance of the QER Loan of approximately $843,000 by issuing 141,186 shares of its common stock with a fair value of $744,000 to RBC. The Company expects to recover the full amount of the $843,000 payment to RBC in June 2012.   The settlement of the QER Loan was facilitated by the restructuring of a prior loan that met the criteria under accounting guidance to be classified as a troubled debt restructuring. The Company had previously recorded a gain on debt restructuring related to the QER Loan of $2.9 million in 2010. Following a re-evaluation of the maximum sum of future cash flows that would be paid to RBC, the Company recorded an additional gain of $1.6 million during the second quarter of 2011. The gain includes $799,000 of accrued interest that was forgiven at the time the balance of the loan was settled. The gain is reflected as a “gain on forgiveness of debt” in the consolidated statement of operations.

amounts used for income tax reporting. Deferred tax assets are reduced by a valuation allowance if it is deemed more likely than not that some or all of the deferred assets will not be realized based on the weight of all available evidence. Based on the negative evidence that existed at each reporting period, the Company recorded a full valuation allowance against its net deferred tax asset at December 31, 2009, 2010, and 2011.

carryforwards that are available to reduce future U.S. taxable income. If not utilized, such carryforwards will expire from 2021 through 2031. The Company’s ability to utilize NOL carryforwards to reduce future federal taxable income and federal income tax of the Company is subject to various limitations under Internal Revenue Code (“IRC”) Section 382. The utilization of such carryforwards may be limited upon the occurrence of certain ownership changes, including the issuance or exercise of rights to acquire stock, the purchase or sale of stock by 5% stockholders, as defined in the Treasury regulations, and the offering of stock of PostRock during any three-year period resulting in an aggregate change of more than 50% in the beneficial ownership of PostRock. The Company experienced ownership changes within the meaning of IRC Section 382 on November 14, 2005, March 5, 2010, and September 21, 2010. The Company has NOL carryforwards of approximately $254 million at December 31, 2011 that are available to reduce future U.S. taxable income in certain circumstances. At December 31, 2011, $228 million of federal NOL carryforwards are subject to the IRC Section 382 limitation and it is anticipated that $207 million of these federal NOL carryforwards will expire unused due to the IRC Section 382 limitation. As a result, only $47 million of federal NOL carryforwards have been recorded as a deferred tax asset. The limitation does not result in a current federal tax liability for the period ending December 31, 2011. In December 2010, certain assets located in Wetzel County, West Virginia, were sold to MHR (see Note 3), resulting in a recognized built-in loss of $5.0 million. The Company also had recognized built-in losses of $46.8 million due to depreciation and depletion expense limitations as a result of the ownership changes that occurred in March and September of 2010. It is anticipated that $50.8 million of these recognized built-in losses will expire unused. FASB ASC 740-10 provides guidance for recognizing and measuring uncertain tax positions. Based upon the provision of FASB ASC 740-10, the Company did not record any amounts for uncertain tax benefits upon adoption of the standard and has no amounts recorded for uncertain tax benefits at December 31, 2011. Accordingly, there has been no change in unrecognized tax benefits during the year. The Company files income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. Tax years ended December 31, 2008, 2009 and 2010 remain open for examination by the relevant taxing authorities. In addition, the Company’s tax returns for the tax years ended December 31, 2001, through December 31, 2007, can be examined and adjustments made to the amount of net operating losses flowing from those years into an open tax year. However, no assessment of income tax may generally be made for those years on which the statute has closed. The Company’s policy is to recognize interest and penalties, if any, related to unrecognized tax benefits as income tax expense.

Note 12—Redeemable Preferred Stock and Warrants On September 21, 2010, the Company issued to White Deer Energy L.P. and its affiliates (“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 $60 million. The initial investment was recognized on the Company’s consolidated balance sheet based on the relative fair values of the Series A Preferred Stock, Series B Preferred Stock and the warrants allocated to the $60 million of gross proceeds. The Series A Preferred Stock is entitled to a cumulative dividend of 12% per year on its liquidation preference, compounded quarterly. The liquidation preference was $60 million on the closing date of the equity investment and will increase by the amount of dividends paid in kind. The Company is not required to pay cash dividends until July 1, 2013. Any dividends prior to that time not paid in cash will accrue as additional liquidation preference. Subsequent to July 1, 2013, dividends are required to be paid in cash, subject to the legal availability of funds for the declaration and payment thereof, 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 does not vote generally with the common stock, but has 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. Prior to July 1, 2013, if dividends on the Series A Preferred Stock 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. 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. At January 1, 2012, with respect to the votes applicable to the Series B Preferred Stock, the holders of the Series B Preferred Stock and their affiliates are limited to 45% of the votes applicable to all outstanding voting stock; such holders and their affiliates may vote any shares of common stock held by them without regard to that limit. When the Company accrues dividends on its Series A Preferred Stock on a quarterly dividend payment date, it records the increase in liquidation preference and the issuance of additional warrants by allocating their relative fair values to the amount of accrued dividends. The allocation results in an increase to the Company’s temporary equity related to the Series A Preferred Stock and an increase to additional paid in capital related to the additional warrants issued. The increase to additional paid in capital related to additional warrants issued was $872,000 and $3.2 million for the years ended December 31, 2010 and 2011, respectively.   The following table summarizes changes in the Series A Preferred Stock and associated warrants since White Deer’s initial investment on September 21, 2010.   <table cellspacing="0" cellpadding="0" width="100%" border="0"

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 which would have required recognition as a 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.

Note 13—Stockholders’ Equity Restricted share and stock option awards of QRCP prior to the Recombination were made under the 2005 Omnibus Stock Award Plan (as amended). 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”) of which 850,000 shares were initially authorized for future stock and option awards with an additional 2,000,000 shares authorized in 2011. 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 Predecessors and the Predecessors’ consolidated subsidiaries recognized $393,000 of compensation expense related to the accelerated vesting discussed above. All remaining unvested awards were converted to 595,923 PostRock restricted share awards.   A summary of changes in the non-vested restricted shares for PostRock and its Predecessors for the periods presented is below:   <table cellspacing="0" cellpadding="0" width="76%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="64%"> </td> <td valign="bottom"

The Company determines the fair value of stock option awards using the Black-Scholes option pricing model. The expected life of the option is estimated based upon historical exercise behavior. The expected forfeiture rate was estimated based upon historical forfeiture experience. The volatility assumption was estimated based upon expectations of volatility over the life of the option as measured by historical and implied volatility. The risk-free interest rate was based on the U.S. Treasury rate for a term commensurate with the expected life of the option. The dividend yield was based upon a 12-month average dividend yield.

Note 14—Commitments and Contingencies Litigation—The Company is subject, from time to time, to certain legal proceedings and claims in the ordinary course of conducting its business. It records a liability related to its legal proceedings and claims when it has determined that it is probable that it will be obligated to pay and the related amount can be reasonably estimated. Except for those legal proceedings listed below, it believes there are no pending legal proceedings in which it is currently involved which, if adversely determined, would have a material adverse effect on its financial position, results of operations or cash flow. The Company had been sued in royalty owner lawsuits filed in Oklahoma and Kansas. In Oklahoma, suits by a group of individual royalty owners and by a putative class representing all remaining royalty owners were filed in the District Court of Nowata County, Oklahoma. Generally, the lawsuits alleged that the Company wrongfully deducted post-production costs from the plaintiffs’ royalties and engaged in self-dealing agreements resulting in a less than market price for the gas production. The Company denied the allegations. Settlements were reached in each of the cases, and on July 28, 2011, the Court entered a final order approving the class action settlement. On July 29, 2011, the Company paid $5.6 million in settlement of both Oklahoma suits. The Kansas lawsuit was a putative class action filed in the United States District Court for the District of Kansas, brought on behalf of all the Company’s royalty owners in that state. Plaintiffs generally alleged that the Company failed to properly make royalty payments by, among other things, charging post-production costs to royalty owners in violation of the underlying lease contracts, paying royalties based on sale point volumes rather than wellhead volumes, allocating expenses in excess of the actual and reasonable post-production costs incurred, allocating production costs and marketing costs to royalty owners, and making royalty payments after the statutorily prescribed time for doing so without paying interest thereon. We denied plaintiffs’ claims. The parties reached a settlement and on December 30, 2011, the Court entered an order certifying a class for settlement purposes consisting of all current and former PostRock royalty and overriding royalty owners, approving the parties’ settlement and dismissing the action. The settlement includes a payment of $3.0 million that was made in January 2012, and a payment of $4.5 million to be made by January 31, 2013, for a total of $7.5 million. At December 31, 2011, the Company had reserved $7.1 million for the estimated cost to resolve the Kansas action. The $7.1 million included the $3.0 million paid in January 2012 and $4.1 million representing the present value of an additional $4.5 million to be paid by January 31, 2013. The $4.1 million reserve is reflected in other noncurrent liabilities in the consolidated balance sheet. The Company recorded litigation reserve expense related to its Oklahoma and Kansas lawsuits of $11.5 million for the year ended December 31, 2011. Environmental Matters—At December 31, 2010 and 2011, there were no known environmental or regulatory matters related to our operations which are reasonably expected to result in a material liability to us. Like other oil and gas producers and marketers, our operations are subject to extensive and rapidly changing federal and state environmental regulations governing air emissions, wastewater discharges, and solid and hazardous waste management activities. Therefore it is extremely difficult to reasonably quantify future environmental related expenditures. Operating Lease Commitments—The Company has lease agreements to obtain natural gas compressors as and when required. Terms of the leases on the gas compressors call for a minimum obligation of one year and are month to month thereafter. In addition, the Company also has operating leases for office space, warehouse facilities and office equipment expiring in various years through 2017.   Future minimum rental payments under all non-cancelable operating leases at December 31, 2011, were as follows (in thousands):   <table cellspacing="0" cellpadding="0" width="68%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="86%"> </td> <td valign="bottom" width="8%"> </td> <td> </td> <td> </td> <td> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Year ending December 31, </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> </tr> <tr> <td valign="top"> 2012 </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">2,172</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> 2013 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,045</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> 2014 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">900</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> 2015 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">771</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> 2016 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">696</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Thereafter </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">422</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr> <td valign="top"> Total minimum lease obligations </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">6,006</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr>  </table> Total rental expense under cancelable and non-cancelable operating leases was $17.3 million for the year ended December 31, 2009, $2.5 million and $13.1 million for the periods from January 1 to March 5, 2010, and March 6 to December 31, 2010, and $13.6 million for the year ended December 31, 2011.

Note 16—Related Party Transactions During the period from 2005 to 2007, our former chief executive officer made certain unauthorized transfers, repayments and re-transfers of funds totaling $10.0 million to entities that he controlled. During 2009, under the terms of a settlement agreement reached in May 2009, the Company received approximately $2.4 million in cash, 60% of the controlled entity’s interest in a natural gas well located in Louisiana and a landfill natural gas development project located in Texas, all of our former chief executive officer’s equity interest in STP Newco, Inc. which owns certain oil producing properties in Oklahoma and other assets for a total estimated net fair value of $3.4 million. During 2010, the Company recovered an additional $1.6 million in assets related to the misappropriation of which $1.1 million was received in cash. No additional recoveries were made during 2011.

Note 17—Operating Segments In accordance with FASB ASC 280, Segment Reporting, the Company divides its operations into two reportable business segments: Production The Company’s production segment includes the acquisition, exploration, development, production and gathering of crude oil and natural gas. Pipeline The Company’s pipeline segment consists of a 1,120 mile interstate natural gas pipeline (the “KPC Pipeline”), which transports natural gas from northern Oklahoma and western Kansas to Wichita and Kansas City. The Company’s Chief Operating Decision Maker evaluates the performance of the reportable segments based on “Income (Loss) before income taxes and noncontrolling interests.” Both of these segments are exclusively located in the continental United States, and each segment uses the same accounting policies as those described in the summary of significant accounting policies (see Note 2—Summary of Significant Accounting Policies). The Company’s reportable segments are strategic business units that offer different products and services. Each segment is managed separately because each segment involves different products and marketing strategies. The Company does not allocate income taxes to its operating segments.   Operating segment data for the periods indicated is as follows (in thousands):   <table cellspacing="0" cellpadding="0"

Note 18—Profit Sharing Plan Substantially all of the Company’s employees are covered by a profit sharing plan under Section 401(k) of the Internal Revenue Code. Eligible employees may make contributions to the plan by electing to defer some of their compensation. Beginning in 2011, the Company contributed two percent of employees’ annual compensation regardless whether contributions were made by the employee. The Company would also match 100% of employee contributions in excess of two percent up to a total of four percent of annual compensation. Employees vest 50% in Company contributions in their second year of service and 100% in their third year of service.

Cawley, Gillespie & Associates, Inc., independent reserve engineering firm, was retained to perform the annual year-end independent evaluation of the Company’s proved reserves. Users of this information should be aware that the process of estimating quantities of “proved,” “proved developed” and “proved undeveloped” oil and gas reserves is very complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. The data for a given reservoir may also change substantially over time as a result of numerous factors including, but not limited to, additional development activity, evolving production history, and continual reassessment of the viability of production under varying economic conditions. Consequently, material revisions (upwards or downward) to existing reserve estimates may occur from time to time. Although every reasonable effort is made to ensure that reserve estimates reported represent the most accurate assessments possible, the significance of the subjective decisions required and variances in available data for various reservoirs make these estimates generally less precise than other estimates presented in connection with financial statement disclosures. The table below presents changes in proved developed and undeveloped reserves of our consolidated entities. During the fourth quarter of 2010, the Company reclassified the operations and assets of its gathering system in the Cherokee Basin from its former natural gas pipelines segment to its production segment. Prior to the reclassification, the determination of the Company’s oil and gas reserves included gathering costs based on the gathering rate charged under the midstream services and gas dedication agreement between Bluestem Pipeline, LLC and QELP. The agreement was no longer in effect subsequent to the restructuring of the Company’s credit facilities at the end of the third quarter in 2010. Gathering costs included in the Company’s oil and gas reserves at December 31, 2010, were subsequently based on projected operating expenses of the gathering system which are lower than the costs under the midstream services and gas dedication agreement. In addition, future oil and gas development costs now include anticipated capital expenditures associated with the gathering system. These changes are reflected in the rollforward of the Company’s reserves for 2010.   <table cellspacing="0" cellpadding="0" width="76%" border="0" style="border-collapse:collapse; text-align: left"
