Rex Energy Corporation, together with our subsidiaries (the “Company”), is an independent oil, natural gas liquid (“NGL”) and natural gas company with operations currently focused in the Appalachian and Illinois Basins. In the Appalachian Basin, we are focused on our Marcellus Shale, Utica Shale and Upper Devonian (“Burkett”) Shale drilling and exploration activities. In the Illinois Basin, we are focused on developmental oil drilling and the implementation of enhanced oil recovery (“EOR”) on our properties. We pursue a balanced growth strategy of exploiting our sizable inventory of high potential exploration drilling prospects while actively seeking to acquire complementary oil and natural gas properties. In addition to our drilling and exploration activities, we are also engaged in oil and gas field services, where we provide water sourcing, water disposal and water transfer capabilities for completion operations.

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of all of our wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated. Unless otherwise indicated, all references to “Rex Energy Corporation,” “our,” “we,” “us” and similar terms refer to Rex Energy Corporation and its subsidiaries together. In preparing the accompanying financial statements, management has made certain estimates and assumptions that affect reported amounts in the financial statements and disclosures of contingencies.

The interim Consolidated Financial Statements of the Company are unaudited and contain all adjustments (consisting primarily of normal recurring accruals) necessary for a fair statement of the results for the interim periods presented. Actual results may differ from those estimates and results for interim periods are not necessarily indicative of results to be expected for a full year or for previously reported periods due in part, but not limited to, the volatility in prices for crude oil, NGLs and natural gas, future commodity prices for financial derivative instruments, interest rates, estimates of reserves, drilling risks, geological risks, transportation restrictions, the timing of acquisitions, product demand, market consumption, interruption in production, our ability to obtain additional capital, and the success of oil, NGL and natural gas recovery techniques.

Certain amounts and disclosures have been condensed or omitted from these Consolidated Financial Statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Therefore, these interim financial statements should be read in conjunction with the audited Consolidated Financial Statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013.

During December 2011, our board of directors approved a formal plan to sell our DJ Basin assets located in the states of Wyoming and Colorado, for which the final sale was completed in 2013. Pursuant to the rules for discontinued operations, the results of operations are reflected as Discontinued Operations in our Consolidated Statements of Operations. Unless otherwise noted, all disclosures and tables reflect the results of continuing operations and exclude any assets, liabilities or results from our discontinued operations. For additional information see Note 4, Discontinued Operations/Assets Held for Sale, to our Consolidated Financial Statements.

We have two principal reportable segments, which are segregated based on the products and services that each provides: (a) exploration and production, and (b) field services. Our exploration and production segment engages in the exploration, acquisition, development and production of oil, NGLs and natural gas. We have a single, company-wide management team that oversees all properties as a whole rather than isolating operating segments; however, we do track basic operational data by area. Our financial performance is measured as a single enterprise and not by individual area. Our field services segment operates and manages water sourcing, water transfer, equipment rental and water disposal services, primarily in the Appalachian Basin. Our field services segment is comprised of operations that have economic characteristics that are distinct from those of our exploration and production segment and is managed by its own unique management team.

We evaluate the performance of our business segments based on net income (loss) from continuing operations, before income taxes. All intercompany transactions, including those between consolidated business segments, are eliminated in consolidation. Summarized financial information concerning our segments is shown in the following table for the three and six months ended June 30, 2014 and 2013 (in thousands):

Future abandonment costs are recognized as obligations associated with the retirement of tangible long-lived assets that result from the acquisition and development of the asset. We recognize the fair value of a liability for a retirement obligation in the period in which the liability is incurred. For natural gas and oil properties, this is the period in which the natural gas or oil well is acquired or drilled. The future abandonment cost is capitalized as part of the carrying amount of our natural gas and oil properties at its discounted fair value. The liability is then accreted each period until the liability is settled or the natural gas or oil well is sold, at which time the liability is reversed. If the fair value of a recorded future abandonment cost changes, a revision is recorded to both the asset retirement obligation and the asset retirement cost.

Accretion expense totaled approximately $0.9 million and $1.6 million for the three and six months ended June 30, 2014, respectively, and $0.5 million and $1.1 million for the three and six months ended June 30, 2013, respectively. These amounts are recorded as depreciation, depletion, amortization and accretion (“DD&A”) expense on our Consolidated Statements of Operations. We account for future abandonment costs that relate to wells that are drilled jointly based on our working interest in those wells.

¹ Includes approximately $2.9 million of short-term future abandonment costs, which are classified as Accrued Liabilities on our Consolidated Balance Sheet.

During December 2011, our board of directors approved a formal plan to sell our DJ Basin assets located in the states of Wyoming and Colorado. During 2012, we sold various parcels of acreage throughout our DJ Basin holdings at varying prices, much

of which was lower than the existing carrying value of similar remaining acreage at the time of sale. During the first quarter of 2013, we entered an agreement to sell our remaining DJ Basin assets for $3.1 million. This transaction closed during the second quarter of 2013 and resulted in a gain of approximately $1.0 million. Since that time, we have had no assets or liabilities related to the DJ Basin or continuing cash flows from this region.

Summarized financial information for Discontinued Operations is set forth in the table below, and does not reflect the costs of certain services provided. Such costs, which were not allocated to the Discontinued Operations, were for services, including legal counsel, insurance, external audit fees, payroll processing, certain human resource services and information technology systems support.

There were no significant asset acquisitions or dispositions during the three and six-month periods ended June 30, 2014.

In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposal of Components of an Entity. The amendments in this ASU change the criteria for reporting discontinued operations while enhancing the disclosures in this area. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. In addition, the new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. The amendments in this ASU are effective in the first quarter of 2015 for public organizations with calendar year ends. We are currently evaluating the potential effect of this ASU but do not believe that it will have a material impact on our Consolidated Financial Statements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The amendments in this ASU affects any entity using U.S. GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services by following five steps:

An entity should apply the amendments in this ASU using one of the following two methods:

For public entities, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. We are currently evaluating the potential impact of this ASU.

In June 2014, the FASB issued ASU 2014-12, Compensation – Stock Compensation. The amendments in this ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. Entities may apply the amendments in this ASU either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new awards thereafter. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. We are currently evaluating the potential effect of this ASU but do not believe that it will have a material impact on our Consolidated Financial Statements.

By using derivative instruments to hedge exposure to changes in commodity prices, we are exposed to credit risk and market risk. Credit risk is the failure of the counterparties to perform under the terms of the derivative contract. When the fair value of the derivative is positive, the counterparty owes us, which creates repayment risk. We minimize the credit or repayment risk in derivative instruments by entering into transactions with high-quality counterparties. Our counterparties are investment grade financial institutions and lenders in our Senior Credit Facility (see Note 8, Long-term Debt, to our Consolidated Financial Statements). We have a master netting agreement in place with our counterparties that provides for the offsetting of payables against receivables from separate derivative contracts. None of our derivative contracts have a collateral provision that would require funding prior to the scheduled cash settlement date. For additional information, see Note 9, Fair Value of Financial and Derivative Instruments, to our Consolidated Financial Statements.

We also depend on a relatively small number of purchasers for a substantial portion of our revenue. For the six months ended June 30, 2014, approximately 95.7% of our commodity sales came from five purchasers, with the largest single purchaser accounting for 35.9% of commodity sales. We believe the continued growth in our Appalachian Basin operations will help us to minimize our future risks by diversifying our ratio of oil, NGLs and natural gas sales as well as the quantity of purchasers.

We maintain a revolving credit facility evidenced by a credit agreement, dated March 27, 2013 (the “Senior Credit Facility”) As of June 30, 2014, the borrowing base under the Senior Credit Facility was $375.0 million; however, the Senior Credit Facility may be increased to up to $500.0 million upon re-determinations of the borrowing base, consent of the lenders and other conditions prescribed by the agreement. Within the Senior Credit Facility, a letter of credit subfacility exists of up to $60.0 million of letters of credit. The Senior Credit Facility provides that the borrowing base will be re-determined semi-annually by the lenders. Subsequent to our offering of 6.25% senior notes in July 2014, our borrowing base was immediately reduced to approximately $293.8 million. For additional information on our offering of 6.25% senior notes, see Note 20, Subsequent Events, to our Consolidated Financial Statements. As of June 30, 2014, loans made under the Senior Credit Facility were set to mature on March 27, 2018. In certain circumstances, we may be required to prepay the loans. Management does not believe that a prepayment will be required within the next twelve months. As of June 30, 2014 and December 31, 2013, we had approximately $200.0 million and $59.0 million, respectively, of outstanding borrowings under the Senior Credit Facility.

At our election, borrowings under the Senior Credit Facility bear interest at a rate per annum equal to the “Adjusted LIBO Rate” or the “Alternate Base Rate” (each as defined below), plus, in each case, an applicable per annum margin. The “Adjusted LIBO Rate”

is equal to the product of: (i) the London Interbank Offered Rate for deposits with a maturity comparable to the borrowings (the “LIBO Rate”) multiplied by (ii) the statutory reserve rate. The Alternative Base Rate is equal to the greater of: (i) KeyBank’s announced prime rate; (ii) the federal funds effective rate from time to time plus 0.5%; and (iii) Adjusted LIBO Rate for a one month interest period plus 1.0%. The applicable per annum margin, in the case of loans bearing interest at the Adjusted LIBO Rate, ranges from 150 to 250 basis points, and the applicable per annum margin, in the case of loans bearing interest at the Alternate Base Rate, ranges from 50 to 150 basis points, in each case, determined based upon our borrowing utilization at such date of determination. Upon the occurrence and continuance of an event of default, all outstanding loans shall bear interest at a rate equal to 200 basis points per annum plus the then effective rate of interest. Interest is payable on the last day of the relevant interest period (or at least every three months), in the case of loans bearing interest at the Adjusted LIBO Rate, and quarterly, in the case of loans bearing interest at the Alternate Base Rate.

Under the Senior Credit Facility, we may enter into commodity swap agreements with counterparties approved by the lenders, provided that the notional volumes for such agreements, when aggregated with other commodity swap agreements then in effect (other than basis differential swaps on volumes already hedged pursuant to other swap agreements), do not exceed, as of the date the swap agreement is executed, 85% of the reasonably anticipated projected production from our proved developed producing reserves for the 36 months following the date such agreement is entered into, and 75% thereafter, for each of crude oil and natural gas, calculated separately. We may also enter into interest rate swap agreements with counterparties approved by the lenders that convert interest rates from floating to fixed provided that the notional amounts of those agreements, when aggregated with all other similar interest rate swap agreements then in effect, do not exceed the greater of $20 million and 75% of the then outstanding principal amount of our debt for borrowed money which bears interest at a floating rate. As of June 30, 2014, we were in compliance with all of these metrics, and there were no existing defaults or events of default under our Senior Credit Facility.

The Senior Credit Facility contains covenants that restrict our ability to, among other things, materially change our business; approve and distribute dividends; enter into transactions with affiliates; create or acquire additional subsidiaries; incur indebtedness; sell assets; make loans to others; make investments; enter into mergers; incur liens; and enter into agreements regarding swap and other derivative transactions (for further information, see Note 7, Concentrations of Credit Risk, and Note 9, Fair Value of Financial Instruments and Derivative Instruments, to our Consolidated Financial Statements). Borrowings under the Senior Credit Facility have been used to finance our working capital needs and for general corporate purposes in the ordinary course of business, including the exploration, acquisition and development of oil and gas properties. Obligations under the Senior Credit Facility are secured by mortgages on the oil and gas properties of our subsidiaries located in Pennsylvania, Ohio, Illinois and Indiana. We are required to maintain liens covering our oil and gas properties representing at least 80% of our total value of all oil and gas properties.

The Senior Credit Facility also requires we meet, on a quarterly basis, minimum financial requirements of consolidated current ratio, EBITDAX to interest expense and total debt to EBITDAX. EBITDAX is a non-GAAP financial measure used by our management team and by other users of our financial statements, such as our commercial bank lenders, which adds to or subtracts from net income the following expenses or income for a given period to the extent deducted from or added to net income in such period: interest, income taxes, depreciation, depletion, amortization, unrealized gains and losses from derivatives, exploration expense and other similar non-cash activity. The Senior Credit Facility requires that as of the last day of any fiscal quarter, our ratio of consolidated current assets, which includes the unused portion of our borrowing base, as of such day to consolidated current liabilities as of such day, known as our current ratio, must not be less than 1.0 to 1.0. Our current ratio as of June 30, 2014 was approximately 2.2 to 1.0. Additionally, the Senior Credit Facility requires that as of the last day of any fiscal quarter, our ratio of EBITDAX for the trailing twelve months to interest expense for such period, known as our interest coverage ratio, must not be less than 3.0 to 1.0. Our interest coverage ratio as of June 30, 2014 was approximately 4.8 to 1.0. Additionally, as of the last day of any fiscal quarter, our ratio of total debt to EBITDAX for the trailing twelve months must not exceed 4.25 to 1.0. Our ratio of total debt to EBITDAX as of June 30, 2014 was approximately 3.4 to 1.0.

As of June 30, 2014 and December 31, 2013, we had recorded on our Consolidated Balance Sheet approximately $352.9 million and $353.1 million of 8.875% senior notes due 2020 (the “Senior Notes”), which is inclusive of a net premium of $2.9 million and $3.1 million, respectively. The amortization of our net premium during the first six months of 2014, which follows the effective interest method, was approximately $0.2 million and was recorded as a credit to Interest Expense on our Consolidated Statement of Operations. Bond issuance costs of $8.4 million were recorded as Deferred Financing Costs and Other Assets-Net on our Consolidated Balance Sheet and are being amortized over the term of the Senior Notes as Interest Expense on our Consolidated Statements of Operations using the effective interest method.

The Senior Notes are fully and unconditionally guaranteed on a senior unsecured basis by certain of our existing and future domestic subsidiaries. In addition, there are no significant restrictions on our ability, or the ability of any subsidiary guarantor, to receive funds from our subsidiaries through dividends, loans, advances or otherwise. For additional information on our guarantor and non-guarantor subsidiaries, see Note 19, Condensed Consolidating Financial Information, to our Consolidated Financial Statements.

In addition to the Senior Credit Facility and the Senior Notes, we may, from time to time in the normal course of business finance assets such as vehicles, office equipment and leasehold improvements through debt financing at favorable terms. Long-term debt and other obligations consisted of the following at June 30, 2014 and December 31, 2013:

On October 18, 2013, Water Solutions Holdings entered into agreements with M&T Bank (“M&T”) to obtain a revolving line of credit (“Demand Note”) and an equipment line of credit (“Equipment Term Note”).

The borrowing base for the Demand Note is the lesser of (a) $8.0 million, increased from $4.0 million at December 31, 2013, or (b) 80% of Water Solutions’ Accounts Receivable which are less than 90 days old. Borrowings under the Demand Note are to be used for working capital and general corporate purposes. At Water Solutions’ election, borrowings under the Demand Note bear interest per annum equal to an adjusted LIBOR rate or an adjusted base rate, as defined below. The adjusted LIBOR rate is equal 2.75 percentage points above the greater of (a) one-month LIBOR, adjusting daily, or (b) one-day LIBOR. The adjusted base rate is equal to 2.0 percentage points above the rate of interest announced by M&T as its prime rate. All interest that is accrued through the last day of any calendar month will be due and payable by the tenth day of the next calendar month. While there is no stated maturity date for amounts outstanding under the Demand Note, in certain circumstances, Water Solutions may be required to repay amounts outstanding on demand from M&T. As of June 30, 2014, there was approximately $3.9 million outstanding under the Demand Note.

The Demand Note agreement does not contain any collateral requirements on behalf of Water Solutions, nor does it contain any financial covenant requirements.

Maximum borrowings under the Equipment Term Note are equal to $6.0 million and are to be used for purposes of making equipment or vehicle acquisitions up to a maximum of 80% of the costs of such assets. Borrowings under the Equipment Term Note bear interest per annum equal to the three month LIBOR plus 3.0 percentage points. All interest is due and payable on the first day of each fiscal quarter. Maturity dates will vary with each borrowing, but will generally be three to four years from the date of borrowing. In certain circumstances, Water Solutions may be required to prepay any loans that are outstanding. As of June 30, 2014, there was approximately $3.9 million outstanding under the Equipment Term Note.

The Equipment Term Note contains covenants that restrict Water Solutions’ ability to, among other things, materially change their business; incur indebtedness; make loans to others; incur liens; make investments; or become a guarantor. Borrowings under the Equipment Term Note are collateralized with liens covering 80% of the value of assets purchased with associated loans under the Equipment Term Note. The Equipment Term Note also requires that Water Solutions meet certain financial covenants regarding tangible net worth, fixed charge coverage ratio and a debt to EBITDA ratio (as defined in the Equipment Term Note). EBITDA is a non-GAAP financial measure used by the management of Water Solutions and by other users of Water Solutions’ financial statements, such as commercial bank lenders, which adds to or subtracts from net income the following expenses or income for a given period to the extent deducted from or added to net income in such period: interest, income taxes, depreciation, amortization and other similar non-cash activity. The Equipment Term Note requires that tangible net worth (i) not be less than $2.5 million measured annually, and (ii) not be less than $2.5 million plus 30% of annual net income commencing with the fiscal year ended December 31, 2013 and each fiscal year thereafter. As of December 31, 2013, Water Solutions’ net worth was approximately $9.2 million. Also, Water Solutions’ fixed charge coverage ratio for four consecutive fiscal quarters ending at the end of each fiscal quarter shall not be less than 1.75 to 1.0. As of June 30, 2014, Water Solutions’ fixed charge coverage ratio was approximately 2.1 to 1.0. Water Solutions’ debt to EBITDA ratio for the trailing 12 month period ending on the last day of the measurement period shall not be greater than 2.25 to 1.0. As of June 30, 2014, Water Solutions’ debt to EBITDA ratio was approximately 1.1 to 1.0.

The following is the principal maturity schedule for debt outstanding as of June 30, 2014:

Our results of operations and operating cash flows are impacted by changes in market prices for oil, natural gas and NGLs. To mitigate a portion of the exposure to adverse market changes, we enter into oil, natural gas and NGL commodity derivative instruments to establish price floor protection. As such, when commodity prices decline to levels that are less than our average price floor, we receive payments that supplement our cash flows. Conversely, when commodity prices increase to levels that are above our average price ceiling, we make payments to our counterparties. We do not enter into these arrangements for speculative trading purposes. As of June 30, 2014 and December 31, 2013, our commodity derivative instruments consisted of fixed rate swap contracts, puts, collars, swaptions, deferred put spreads, cap swaps, basis swaps and three-way collars. We did not designate these instruments as cash flow hedges for accounting purposes. Accordingly, associated unrealized gains and losses are recorded directly as Gain (Loss) on Derivatives, Net.

Swap contracts provide a fixed price for a notional amount of sales volumes. Collars contain a fixed floor price (“put”) and ceiling price (“call”). The put options are purchased from the counterparty by our payment of a cash premium. If the put strike price is greater than the market price for a settlement period, then the counterparty pays us an amount equal to the product of the notional quantity multiplied by the excess of the strike price over the market price. The call options are sold to the counterparty, for which we receive a cash premium. If the market price is greater than the call strike price for a settlement period, then we pay the counterparty an amount equal to the product of the notional quantity multiplied by the excess of the market price over the strike price. A three-way collar is a combination of options, a sold call, a purchased put and a sold put. The purchased put establishes a minimum price unless the market price falls below the sold put, at which point the minimum price would be the settlement price plus the difference between the purchased put and the sold put strike price. The sold call establishes a maximum price we will receive for the volumes under contract. Deferred put spread contracts are similar to three-way collars except that there is no maximum price ceiling established. Swaption agreements provide options to counterparties to extend swaps into subsequent years. Similar to a deferred put spread and a three-way collar, a cap swap provides a sold put in combination with a swap. Should prices fall below the sold put, we would receive the settlement price plus the differential between the sold put and the swap. Basis swaps are arrangements that guarantee a price differential from a specified delivery point. Currently, our basis swaps provide basis protection between Henry Hub and Dominion Appalachia pricing.

We enter into the majority of our derivative arrangements with five counterparties and have a netting agreement in place with these counterparties. We do not obtain collateral to support the agreements, but we believe our credit risk is currently minimal on these transactions. For additional information on the credit risk regarding our counterparties, see Note 7, Concentrations of Credit Risk, to our Consolidated Financial Statements.

None of our commodity derivatives are designated for hedge accounting but are, to a degree, an economic offset to our commodity price exposure. We utilize the mark-to-market accounting method to account for these contracts. We recognize all gains and losses related to these contracts in the Consolidated Statements of Operations as Gain (Loss) on Derivatives, Net under Other Expense. We paid net cash settlements of $2.0 million and $7.2 million in relation to our commodity derivatives during the three and six months ended June 30, 2014, respectively, and received net cash settlements of $1.1 million and $4.8 million in relation to our commodity derivatives for the three and six months ended June 30, 2013, respectively.

As of June 30, 2014, we had over 90.0% of our annualized 2014 oil production hedged through the remainder of 2014, over 80.0% and 40.0% of our annualized 2014 natural gas production hedged through the remainder of 2014 and 2015, respectively, and over 70.0% of our annualized 2014 NGL production hedged through the remainder of 2014. These percentages exclude the effects of our basis swaps and do not include any estimated impact of increased production from future and completion or the natural decline of our oil and gas production.

We are exposed to interest rate risk on our long-term fixed and variable interest rate borrowings. Fixed rate debt, where the interest rate is fixed over the life of the instrument, exposes us to changes in the market interest rates which are lower than our current fixed rate. Variable rate debt, where the interest rate fluctuates, exposes us to changes in market interest rates, which may increase over time. As of June 30, 2014 and December 31, 2013, we had approximately $200.0 million and $59.0 million outstanding under our Senior Credit Facility, respectively, which is subject to variable rates of interest and $350.0 million of Senior Notes outstanding subject to a fixed interest rate. See Note 8, Long-Term Debt, to our Consolidated Financial Statements for additional information on our Senior Credit Facility and Senior Notes.

As of December 31, 2013, we had a $25.0 million notional fixed-to-variable interest rate swap to manage our interest rate exposure related to the Senior Notes. Prior to 2013, we did not have any interest rate swap agreements. During the three months ended June 30, 2014, we terminated our interest rate swap for net proceeds of approximately $0.6 million. We utilized the mark-to-market accounting method to account for our interest rate swap. We recognized all gains and losses related to this contract in the Consolidated Statements of Operations as Gain (Loss) on Derivatives, Net under Other Expense. During 2013, there were no cash settlements related to our interest rate swap agreement. During the three and six months ended June 30, 2014, we received cash payments of approximately $0.5 million and $0.9 million, respectively, related to our interest rate swaps. The fair value of our interest rate swap as December 31, 2013, was a liability of approximately $0.2 million.

The following table summarizes the location and amounts of gains and losses on our derivative instruments from continuing operations, none of which are designated as hedges for accounting purposes, in our accompanying Consolidated Statements of Operations for the three and six months ended June 30, 2014 and 2013:

Our derivative instruments are recorded on the balance sheet as either an asset or a liability, in either case measured at fair value. The fair value associated with our derivative instruments was a net liability of approximately $3.9 million and $0.2 million at June 30, 2014 and December 31, 2013, respectively.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the market approach for recurring fair value measurements and attempt to utilize the best available information. We utilize a fair value hierarchy that gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and lowest priority to unobservable inputs (Level 3 measurement). The three levels of fair value hierarchy are as follows:

Level 1—Quoted prices are 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 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Our derivatives, which consist primarily of commodity swaps and collars, are valued using commodity market data which is derived by combining raw inputs and quantitative models and processes to generate forward curves.

Where observable inputs are available, directly or indirectly, for substantially the full term of the asset or liability, the instrument is categorized in Level 2.

Level 3—Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

Our Level 2 fair value measurements are comprised of our derivative contracts, excluding our basis swap derivatives, and are based upon inputs that are either readily available in the public market, such as oil and natural gas futures prices, volatility factors, interest rates and discount rates, or can be confirmed from other active markets. The fair values recorded as of June 30, 2014 and December 31, 2013, were based upon quotes obtained from the counterparties to these contracts and verified by an independent third party.

Our Level 3 fair value measurements are comprised of our natural gas basis swap contracts. The fair values recorded as of June 30, 2014 were based upon quotes obtained from the counterparties to these contracts and verified by an independent third party. The significant unobservable input used in the fair value measurement of our natural gas basis swaps was the estimate of future natural gas basis differentials. Significant variations in price differentials could result in a significantly different fair value measurement.

The significant unobservable inputs and the range and weighted average of these inputs used in the fair value measurements of our natural gas basis swaps as of June 30, 2014 are included in the table below.

During the three and six months ended June 30, 2014, there were no transfers into or out of Level 1 or Level 2 measurements.

The following table presents the fair value hierarchy table for assets and liabilities measured at fair value ($ in thousands):

The value of our oil derivatives are comprised of collar, three-way collar, swap, cap swap and deferred put spread contracts for notional barrels of oil at interval New York Mercantile Exchange (“NYMEX”) West Texas Intermediate (“WTI”) oil prices. The fair value of our oil derivatives as of June 30, 2014 are based on (i) the contracted notional volumes, (ii) independent active NYMEX futures price quotes for WTI oil and (iii) the implied rate of volatility inherent in the contracts. The implied rates of volatility inherent in our contracts were determined based on market-quoted volatility factors. Our gas derivatives are comprised of puts, swaps, swaptions, collars, three way collars, basis swaps, cap swaps, and deferred put spreads contracts for notional volumes of gas contracted at NYMEX Henry Hub (“HH”). The fair values attributable to our gas derivative contracts as of June 30, 2014 are based on (i) the contracted notional volumes, (ii) independent active NYMEX futures price quotes for HH gas, (iii) independent market-quoted forward index prices and (iv) the implied rate of volatility inherent in the contracts. The implied rates of volatility inherent in our contracts were determined based on market-quoted volatility factors. Our NGL derivatives are comprised of swaps for notional volumes of NGLs contracted at NYMEX Mont Belvieu. The fair values attributable to our NGL derivative contracts as of June 30, 2014 are based on (i) the contracted notional volumes, (ii) independent active NYMEX futures price quotes for Mont Belvieu, (iii) independent market-quoted forward index prices and (iv) the implied rate of volatility inherent in the contracts. The implied rates of volatility inherent in our contracts were determined based on market-quoted volatility factors. We classify our derivatives as Level 2 if the inputs used in the valuation models are directly observable for substantially the full term of the instrument; however, if the significant inputs were not observable for substantially the full term of the instrument, we would classify those derivatives as Level 3. We categorize our measurements as Level 2 because the valuation of our derivative instruments are based on similar transactions observable in active markets or industry standard models that primarily rely on market observable inputs. Substantially all of the assumptions for industry standard models are observable in active markets throughout the full term of the instruments.

The table below sets forth a reconciliation of our commodity derivative contracts at fair value on a recurring basis using significant unobservable inputs (Level 3) during the six months ended June 30, 2014 and 2013:

Changes in fair value on our Level 3 commodity derivative contracts outstanding for the six months ended June 30, 2014, resulted in a loss of approximately $2.0 million. This amount has been included in Gain (Loss) on Derivatives, Net in our Consolidated Statements of Operations. There were no outstanding Level 3 commodity derivatives as of June 30, 2013.

We report the fair value of future abandonment costs on a nonrecurring basis in our Consolidated Balance Sheets. We estimate the fair value of future abandonment costs based on discounted cash flow projections using numerous estimates, assumptions and judgments regarding such factors as the existence of a legal obligation for an asset retirement obligation; estimated probabilities, amounts and timing of settlements; estimated plugging costs; the credit-adjusted risk-free rate to be used; and inflation rates. The most significant inputs used in the determination of future abandonment costs are the estimated costs to plug and abandon our wells. Significant changes in the estimated cost to plug and abandon our wells can cause significant changes in the fair value measurement of our future abandonment costs due to the large number of wells that we operate. These inputs are unobservable, and thus result in a Level 3 classification. Refer to Note 3, Future Abandonment Cost, of our Consolidated Financial Statements for further information on future abandonment costs, which include a reconciliation of the beginning and ending balances.

The following table sets forth the fair values of financial instruments that are not recorded at fair value in our Consolidated Financial Statements:

The fair value of the secured lines of credit approximates carrying value based on borrowing rates available to us for bank loans with similar terms and maturities and would be classified as Level 2 in the fair value hierarchy.

The fair value of the Senior Notes uses pricing that is readily available in the public market. Accordingly, the fair value of the Senior Notes would be classified as Level 1 in the fair value hierarchy. The fair value of our capital leases and other obligations are determined using a discounted cash flow approach based on the interest rate and payment terms of the obligations and assumed discount rate. The fair values of the obligations could be significantly influenced by the discount rate assumptions, which is unobservable. Accordingly, the fair value of the capital leases and other obligations would be classified as Level 3 in the fair value hierarchy.

The carrying values of all classes of cash and cash equivalents, accounts receivables and accounts payables are considered to be representative of their respective fair values due to the short term maturities of those instruments.

We recognize deferred income taxes for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and net operating loss and credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of any tax rate change on deferred taxes is recognized in the

period that includes the enactment date of the tax rate change. Realization of deferred tax assets is assessed and, if not more likely than not, a valuation allowance is recorded to write down the deferred tax assets to their net realizable value.

For the six months ended June 30, 2014, our overall effective tax rate on pre-tax income from continuing operations was different than the statutory rate of 35% due primarily to decreases in state taxes, partially offset by section 162(m) limitations. For the six months ended June 30, 2013, our overall effective tax rate on pretax losses from continuing operations was different than the statutory rate of 35% due primarily to state taxes.

Income tax payments made during the three and six months ended June 30, 2014 and 2013 were negligible. We received tax refunds during the three and six months ended June 30, 2014 of approximately $3.4 million as compared to $5.0 million for the three and six months ended June 30, 2013.

We have authorized capital stock of 100,000,000 shares of common stock and 100,000 shares of preferred stock. As of June 30, 2014 and December 31, 2013, we had 54,089,782 and 54,186,490 shares of common stock outstanding, respectively. There were no shares of preferred stock outstanding as of June 30, 2014 and December 31, 2013.

We recognize all share-based payments to employees, including grants of employee stock options, in our Consolidated Statements of Operations based on their grant-date fair values, using prescribed option-pricing models where applicable. The fair value is expensed over the requisite service period of the individual grantees, which generally equals one vesting period. We report any benefits of income tax deductions in excess of recognized financial accounting compensation as cash flows from financing activities, rather than as cash flows from operating activities.

We have granted stock options, stock appreciation rights and restricted stock awards to various employees, non-employee contractors and non-employee directors under the terms of our 2007 Long-Term Incentive Plan, as amended (the “Plan”). The Plan is administered by the Compensation Committee of our Board of Directors (the “Compensation Committee”). Among the Compensation Committee’s responsibilities are: selecting participants to receive awards; determining the form, amount and other terms and conditions of awards; interpreting the provisions of the Plan or any award agreement; and adopting such rules, forms, instruments and guidelines for administering the Plan as it deems necessary or proper. All actions, interpretations and determinations by the Compensation Committee are final and binding. The composition of the Compensation Committee is intended to permit the awards under the Plan to qualify for exemption under Rule 16b-3 of the Exchange Act. In addition, awards under the Plan, including annual incentive awards paid to executive officers subject to section 162(m) of the Internal Revenue Code or covered employees, are intended to satisfy the requirements of section 162(m) to permit the deduction by us of the associated expenses for federal income tax purposes.

All awards granted under the Plan have been issued at the closing price of our common stock on the NASDAQ Global Select Market on the date of the grant. All outstanding stock options have been awarded with five or ten year expiration dates at an exercise price equal to our closing price on the NASDAQ Global Select Market on the day the award was granted. A forfeiture rate based on a blended average of individual participant terminations and number of awards cancelled is used to estimate forfeitures prospectively.

Stock options represent the right to purchase shares of common stock in the future at the fair market value of the stock on the date of grant. In the event that any outstanding award expires, is forfeited, cancelled or otherwise terminated without the issuance of shares of our common stock or is otherwise settled in cash, shares of our common stock allocable to such award, including the unexercised portion of such award, shall again be available for the purposes of the Plan. If any award is exercised by tendering shares of our common stock to us, either as full or partial payment, in connection with the exercise of such award under the Plan or to satisfy

our withholding obligation with respect to an award, only the number of shares of our common stock issued net of such shares tendered will be deemed delivered for purposes of determining the maximum number of shares of our common stock then available for delivery under the Plan. During the three and six months ended June 30, 2014 and 2013, we did not issue options to purchase shares of our common stock.

Stock-based compensation expense relating to stock options outstanding for the three and six months ended June 30, 2014 and 2013 was negligible. The expense related to stock option grants was recorded on our Consolidated Statements of Operations under the heading of General and Administrative Expense. The intrinsic value of stock options exercised for the six months ended June 30, 2014 and 2013, was approximately $0.3 million and $0.2 million, respectively. The total tax benefit was approximately $0.1 million for each of the six-month periods ended June 30, 2014 and 2013, respectively.

A summary of the status of our issued and outstanding stock options as of June 30, 2014 is as follows:

The weighted average remaining contractual term and the aggregate intrinsic value for options outstanding at June 30, 2014 were 3.4 years and $3.0 million, respectively. The weighted average remaining contractual term and the aggregate intrinsic value for options exercisable at June 30, 2014 were 3.5 years and $2.8 million, respectively. As of June 30, 2014, unrecognized compensation expense related to stock options was negligible.

During the six-month period ended June 30, 2014, the Compensation Committee approved the issuance of an aggregate of 17,643 shares of restricted common stock to 12 employees. During the six-month period ended June 30, 2013, the Compensation Committee approved the issuance of an aggregate of 383,384 shares of restricted stock to 40 employees and three non-employees. The shares granted are subject to time vesting and, in some cases, performance-based vesting. The shares will vest on the date on which the Compensation Committee certifies that the performance goals have been satisfied, provided that the recipient has been in continuous employment with us from the grant date through the date upon which the shares are released. Restrictions on the transfer associated with vesting schedules were determined by the Compensation Committee on an individual award basis. The restricted shares of common stock are valued at the closing price of our common stock on the NASDAQ Global Select Market on the date of grant. Upon a “change in control” of us, as such term is defined in the Plan, restrictions on time vesting and performance-based vesting restricted stock will lapse to varying degrees as outlined in each award agreement. Compensation expense associated with the restricted stock awards is recognized on a straight-line basis over the vesting period.

Certain of our outstanding restricted stock awards granted in 2014, 2013 and 2012 are subject to market-based vesting through a calculation of total shareholder return (“TSR”) of our common stock relative to a pre-defined peer group over a three-year period.

The number of shares ultimately awarded will correspond with the final TSR rank amongst the peer group in accordance with the following schedule:

The weighted average fair value of the TSR awards granted as of June 30, 2014 and December 31, 2013 were $10.15 and $12.59 per share, respectively. Average fair values were estimated on the date of each grant using a Monte Carlo Simulation model that estimates the most likely outcome based on the terms of the award and used the following assumptions:

The dividend yield of zero reflects the fact that we have never paid cash dividends on our common stock and have no present intentions of doing so. The risk-free interest rate reflects the U.S. Treasury Constant Maturity rates as of the measurement date, converted into an implied “spot rate” yield. Our expected volatility estimates are based on observed historical volatility of daily stock returns for the three-year period preceding the grant date. Market index is an equal-weight index of the companies in the peer group. Expected life is measured as the grant date through the end of the performance period. Performance and market shares will vest on the date on which the Compensation Committee certifies that the performance goals have been satisfied, provided that the recipient has been in continuous employment with us from the grant date through the third anniversary of the grant date. Compensation expense for the TSR awards is recognized on a straight-line basis over the vesting period.

Compensation expense associated with restricted stock awards totaled $1.1 million and $2.7 million for the three and six-month periods ended June 30, 2014, respectively, and $1.1 million and $2.2 million for the three and six-month periods ended June 30, 2013, respectively. As of June 30, 2014, total unrecognized compensation cost related to restricted common stock grants was approximately $6.8 million, which will be recognized over a weighted average period of 2.0 years.

A summary of the restricted stock activity for the six months ended June 30, 2014 is as follows:

We are involved in various legal proceedings that arise in the ordinary course of our business. Although we cannot predict the outcome of these proceedings with certainty, we do not currently expect these matters to have a material adverse effect on our consolidated financial position or results of operations.

The accrual of reserves for legal matters is included in Accrued Liabilities on our Consolidated Balance Sheets. The establishment of a reserve involves an estimation process that includes the advice of legal counsel and the subjective judgment of management. While we believe that these reserves are adequate, there are uncertainties associated with legal proceedings and we can give no assurance that our estimate of any related liability will not increase or decrease in the future. The reserved and unreserved exposures for our legal proceedings could change based upon developments in those proceedings or changes in the facts and circumstances. It is possible that we could incur losses in excess of the amounts currently accrued. Based on currently available information, we believe that it is remote that future costs related to known contingent liability exposures for legal proceedings will exceed our current accruals by an amount that would have a material adverse effect on our consolidated financial position, although cash flow could be significantly impacted in the reporting periods in which such costs are incurred.

There have been no significant changes with respect to the legal matters disclosed in our Annual Report on Form 10-K for the year ended December 31, 2013.

Due to the nature of the oil and natural gas business, we are exposed to possible environmental risks. We have implemented various policies and procedures to avoid environmental contamination and risks from environmental contamination. We conduct periodic reviews of our policies and properties to identify changes in the environmental risk profile. In these reviews we evaluate whether there is a probable liability, its amount and the likelihood that the liability will be incurred. The amount of any potential liability is determined by considering, among other matters, incremental direct costs of any likely remediation and the proportionate cost of employees who are expected to devote a significant amount of time directly to any remediation effort.

We manage our exposure to environmental liabilities on properties to be acquired by identifying existing problems and assessing the potential liability. As of June 30, 2014, we know of no significant probable or possible environmental contingent liabilities.

At June 30, 2014, we had posted $2.0 million in various letters of credit to secure our drilling and related operations.

As of June 30, 2014, we have lease commitments for various real estate leases. Rent expense is recognized on a straight-line basis and has been recorded in General and Administrative expense on our Consolidated Statements of Operations. Rent expense for the three and six months ended June 30, 2014 and 2013 was $0.2 million and $0.5 million in 2014, respectively, and $0.2 million and $0.3 million in 2013, respectively. Lease commitments by year for each of the next five years are presented in the table below ($ in thousands):

We have a capacity reservation arrangement with a subsidiary of MarkWest Energy Partners, L.P. (“MarkWest”) to ensure sufficient capacity at the cryogenic gas processing plants owned by MarkWest in Butler County, Pennsylvania to process our produced natural gas. In the event that we do not process any gas through the cryogenic gas processing plants, we may be obligated to pay approximately $5.8 million in 2014, $13.0 million in 2015, $14.6 million in 2016, $14.6 million in 2017, $14.6 million in 2018 and $100.7 million thereafter, assuming our average working interest in the region of approximately 70%. Charges incurred for processing capacity with MarkWest were negligible during the three and six-month periods ended June 30, 2014 and 2013.

We have contracted drilling rig services on three rigs to support our Appalachian Basin operations. The minimum cost to retain these rigs would require payments of approximately $3.9 million in 2014, $3.2 million in 2015 and $1.5 million in 2016, which is consistent with our estimated working interest in this project area. We also have agreements for contracted completion services in the Appalachian Basin. The minimum cost to retain the completion services is approximately $2.6 million in 2014 and $5.1 million in 2015, which is consistent with our estimated working interest in this project area.

During the normal course of business, we have entered into certain agreements to ensure the gathering, transportation, processing and sales of specified quantities of our oil, natural gas and NGLs. In some instances, we are obligated to pay shortfall fees, whereby we would pay a fee for any difference between actual volumes provided as compared to volumes that have been committed. In other instances, we are obligated to pay a fee on all volumes that are subject to the related agreement. In connection with our entry into certain of these agreements, we concurrently entered into a guaranty whereby we have guaranteed the payment of obligations under the specified agreements up to a maximum of $406.2 million, which is larger than our estimated minimum obligations due to certain contracts which have minimum commitment volumes and other contracts which contain provisions that require payment on all volumes delivered.

For the three months ended June 30, 2014 and 2013, we incurred expenses related to the transportation, processing and marketing of our oil, natural gas and NGLs of approximately $11.1 million and $5.1 million, respectively. For the six months ended June 30, 2014 and 2013, we incurred expenses related to the transportation, processing and marketing of our oil, natural gas and NGLs of approximately $20.5 million and $10.0 million, respectively. Expense related to these agreements makes up a substantial portion of our Lease Operating Expense, which we expect to continue as existing agreements commence and new transportation, processing and marketing agreements are entered that will enable us to sell our product. Minimum net obligations under these sales, gathering and transportation agreements for the next five years are as follows ($ in thousands):

In 2012, we entered into a drill-to-earn agreement with MFC Drilling, Inc. (“MFC”). Under the terms and conditions of the agreement, we will acquire a minimum, through a drill-to-earn structure, a 62.5% working interest in approximately 4,510 acres in Belmont, Guernsey and Noble Counties, Ohio. The agreement provides that in order for us to earn the 62.5% working interest, we will bear the cost for our 62.5% working interest and 100% of the 15% working interest of MFC until such time that we have met the $14.1 million drilling carry obligation. As of June 30, 2014, the remaining drilling carry obligation balance was approximately $4.8 million. Our 2014 capital budget includes additional development in this area.

In addition to the drilling carry obligation, we are required to meet drilling commitments. Amounts incurred toward the attainment of the drilling commitments are credited towards the drilling carry obligation. Our drilling commitments require us to commence the drilling of at least three Utica Shale wells by November 15 of each year until the carry obligation has been satisfied, with credits given to additional wells drilled beyond the annual commitment. We currently estimate the commitment for each well drilled and completed for our working interest and that of MFC to be approximately $8.0 million to $9.0 million. Should we not comply with the drilling commitments or terminate the agreement, we would be responsible for payment of any remaining drilling carry obligation at that time.

In 2012, Pennsylvania state legislators instituted a natural gas impact fee on producers of unconventional natural gas. The fee will be imposed on every producer of unconventional gas and applies to unconventional wells spud in Pennsylvania regardless of when spudding occurred. The fee for each unconventional gas well is determined using the following matrix, with vertical unconventional gas wells being charged 20% of the applicable rates:

⁽^a⁾ Pricing utilized for determining annual fee is based on the arithmetic mean of the NYMEX settled price for the near-month contract as reported by the Wall Street Journal for the last trading day of each month of a calendar year for the 12-month period ending December 31.

All fees owed will be due on April 1 of each year. For each of the three-month periods ended June 30, 2014 and 2013, we recorded expense of approximately $0.7 million, and $1.3 million for each of the six month periods ended June 30, 2014 and 2013. We record expenses related to the impact fees as Production and Lease Operating Expense.

In addition to the Asset Retirement Obligation discussed in Note 3, Future Abandonment Costs, to our Consolidated Financial Statements, we have withheld from distributions to certain other working interest owners amounts to be applied towards their share of those retirement costs. These amounts totaled $0.1 million and $0.3 million at June 30, 2014 and December 31, 2013, respectively, and are included in Other Liabilities on our Consolidated Balance Sheets.

Basic income per common share is calculated based on the weighted average number of common shares outstanding at the end of the period, excluding restricted stock with performance-based vesting criteria. Diluted income per common share includes the assumed exercise of stock options and performance-based restricted stock which contain conditions that are not earnings or market based, given that the hypothetical effect is not anti-dilutive. For each of the three and six-month periods ending June 30, 2014, stock options to purchase 0.3 million shares of common stock were outstanding but not included in the computation of diluted net income per share primarily due to the estimate of shares that would be repurchased using the treasury method. Performance-based restricted stock awards of 0.8 million shares of common stock for each of the three and six-month periods ended June 30, 2014, were outstanding but not included in the computations of diluted net income per share calculations due to performance metrics that have not yet been attained. For each of the three and six-month periods ending June 30, 2013, stock options to purchase 0.3 million shares of common stock were outstanding but not included in the computation of diluted net income per share primarily due to the estimate of shares that would be repurchased using the treasury stock method. Performance-based restricted stock awards of 0.5 million shares and 0.6 million shares of common stock for the three and six months ended June 30, 2013, respectively, were outstanding but not included in the computations of diluted net income per share due to due to performance metrics that have not yet been attained. The following table sets forth the computation of basic and diluted earnings per common share (in thousands except per share amounts):

In November 2009, we entered into a limited liability agreement with Sand Hills Management, LLC (“Sand Hills”) to form Water Solutions Holdings, LLC (“Water Solutions”) for the purpose of acquiring, managing and operating water treatment, disposal and transportation facilities that are designed to treat, dispose or transport brine and fresh waters used and produced in oil and gas well development activities. As the result of a change in membership interest that occurred on April 1, 2013, Rex Energy Corporation owns a 60% membership interest in Water Solutions and Sand Hills owns a 40% membership interest and serves as the operator of the entity. The change in ownership interests occurred in accordance with the original operating agreement which stipulated that the change would occur upon the return of our initial capital investments. The change in ownership transaction, in which we retained our controlling financial interest, was accounted for as an equity transaction, with no impact to our Consolidated Statements of Operations. Prior to the change in membership interests, the entity was owned 80% by us and 20% by Sand Hills.

We fully consolidate the accounts of Water Solutions in our financial statements and accounted for the 40% equity interest owned by Sand Hills as a noncontrolling interest. Water Solutions is financed through cash contributions from its members and a credit facility upon which $7.8 million was drawn as of June 30, 2014. As of June 30, 2014, Water Solutions maintained capital leases of approximately $5.5 million. Capital contributions to Water Solutions during the first six months of 2014 and 2013 were negligible. The table below sets forth the carrying amount and classifications of Water Solutions’ assets and liabilities as of June 30, 2014 and December 31, 2013, with no restrictions or obligations to use certain assets to settle associated liabilities:

We own a 40% non-operated interest in RW Gathering, LLC (“RW Gathering”), which owns gas-gathering assets to facilitate development in our Appalachian Basin operations. We recorded our investment in RW Gathering of approximately $18.3 million and $18.7 million as of June 30, 2014 and December 31, 2013, respectively, on our Consolidated Balance Sheets as Equity Method Investments. We did not make any capital contributions to RW Gathering during the first six months of 2014 as compared to contributions of $2.2 million in cash to support gathering line construction during first six months of 2013. RW Gathering recorded net losses from continuing operations of $0.5 million and $1.0 million for each of the three and six months ended June 30, 2014, respectively, as compared to losses of $0.5 million and $0.9 million for each of the three and six months ended June 30, 2013, respectively. The losses incurred were due to insurance fees, bank fees, rent expenses and depreciation expense. Our share of the net loss is recorded on the Statements of Operations as Loss on Equity Method Investments.

During the three and six-month periods ended June 30, 2014, we incurred approximately $0.2 million and $0.4 million for 2014, respectively, as compared to $0.2 million and $0.4 million for 2013, respectively, in compression expenses that were charged to us from Williams Production Appalachia, LLC. These costs are in relation to compression costs incurred by RW Gathering and are recorded as Production and Lease Operating Expense on our Consolidated Statement of Operations. As of June 30, 2014 and December 31, 2013, there were no receivables due from RW Gathering to us.

For the three and six months ended June 30, 2014 and 2013, impairment expenses incurred were negligible. We continually monitor the carrying value of our oil and gas properties and make evaluations of their recoverability when circumstances arise that may contribute to impairment. As of June 30, 2014, we continued to carry the costs of undeveloped properties of approximately $227.8 million on our Consolidated Balance Sheet, which is primarily related to the Marcellus and Utica Shale in the Appalachian Basin and for which we have development, trade or lease extension plans.

For the three and six months ended June 30, 2014, we incurred approximately $1.4 million and $3.4 million in exploration expenses, respectively, as compared to $2.2 million and $4.4 million in exploration expenses for the same periods ended June 30, 2013, respectively. Approximately $2.4 million of the expense incurred in 2014 was due to geological and geophysical type expenditures. An additional $0.8 million of expense was incurred through the payment of delay rentals, predominately in the Appalachian Basin. Approximately $3.8 million of the expense incurred in 2013 was due to geological and geophysical type expenditures. An additional $0.5 million of expense was incurred through the payment of delay rentals, predominately in the Appalachian Basin.

As of June 30, 2014, we had $350.0 million of outstanding Senior Notes due 2020, as shown in Note 8, Long-Term Debt, to our Consolidated Financial Statements. The Senior Notes are guaranteed by certain of our wholly-owned subsidiaries, or guarantor subsidiaries. Unless otherwise noted below, each of the following guarantor subsidiaries are wholly-owned by Rex Energy Corporation and have provided guarantees of the Senior Notes that are joint and several and full and unconditional as of June 30, 2014:

The non-guarantor subsidiaries include certain consolidated subsidiaries, including Water Solutions, R.E. Disposal, LLC, Rex Energy Marketing, LLC and R.E. Ventures Holdings, LLC. We derive much of our business through and derive much of our income through our subsidiaries. Therefore, our ability to make required payments with respect to indebtedness and other obligations depends on the financial results and condition of our subsidiaries and our ability to receive funds from our subsidiaries. As of June 30, 2014, there were no restrictions on the ability of any of the guarantor subsidiaries to transfer funds to us. There may be restrictions for certain non-guarantor subsidiaries.

The following financial statements present condensed consolidating financial data for (i) Rex Energy Corporation, the issuer of the notes, (ii) the combined Guarantors, (iii) the combined other subsidiaries of the Company that did not guarantee the Notes, and (iv) eliminations necessary to arrive at our consolidated financial statements, which include condensed consolidated balance sheets as of June 30, 2014 and December 31, 2013, the condensed consolidating statements of operations for each of the three and six-month periods ended June 30, 2014 and 2013, and the condensed consolidating statements of cash flows for each of the six-month periods ended June 30, 2014 and 2013.

On July 14, 2014, we issued $325.0 million in aggregate principal amount of 6.25% senior notes in an offering at an issue price of 100.0% of the aggregate principal amount of senior notes, due to mature on August 1, 2022. We received net proceeds in the offering of approximately $318.8 million, after discounts and offering expenses. Interest is payable semi-annually at a rate of 6.25% per annum on February 1 and August 1 of each year, with the first interest payment to be made on February 1, 2015. We used the proceeds of the offering to repay all of the borrowings outstanding under our Senior Credit Facility, which was $218.0 million at the time of the payment, and expect to use the remaining proceeds for general corporate purposes.

The following is management’s discussion and analysis of certain significant factors that have affected aspects of our financial position and results of operations during the periods included in the accompanying unaudited financial statements. You should read this in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the audited financial statements for the year ended December 31, 2013 included in our Annual Report on Form 10-K and the unaudited financial statements included elsewhere herein.

We use a variety of financial and operational measurements at interim periods to analyze our performance. These measurements include an analysis of production and sales revenue for the period; EBITDAX, a non-GAAP financial measurement; lease operating expenses per Mcf equivalent (“LOE per Mcfe”); and general and administrative (“G&A”) expenses per Mcfe.

We are an independent oil and gas company operating in the Appalachian Basin and Illinois Basin. In the Appalachian Basin, we are focused on our Marcellus Shale, Utica Shale and Upper Devonian (“Burkett”) Shale drilling and exploration activities. In the Illinois Basin, in addition to our developmental oil drilling, we are focused on the implementation of enhanced oil recovery on our properties. We pursue a balanced growth strategy of exploiting our sizable inventory of high potential exploration drilling prospects while actively seeking to acquire complementary oil and natural gas properties. In addition to our drilling and exploration activities, we are also engaged in oil and gas field services, where we provide water sourcing, water disposal and water transfer solutions for completion operations.

We divide our operations into two principal business segments: (1) exploration and production and (2) field services. We are headquartered in State College, Pennsylvania, and have regional offices in Bridgeport, Illinois; Cranberry, Pennsylvania; and Carrolton, Ohio.

During the three and six months ended June 30, 2014, we produced 10,473 MMcfe and 20,372 MMcfe, respectively, in the Appalachian Basin. In the Illinois Basin, we produced 208 MBbls and 391 MBbls during the three and six months ended June 30, 2014, respectively. Overall, our production for the three and six months ended June 30, 2014 averaged 128,791 Mcfe per day and 125,506 Mcfe per day, respectively. As of June 30, 2014, we had 11.0 gross (8.0 net) wells drilled and awaiting completion. Our drilling and completion activity for the period indicated in each of our regions is set forth in the tables below.

On July 14, 2014, we issued $325.0 in million aggregate principal amount of 6.25% senior notes in an offering at an issue price of 100.0% of the aggregate principal amount of senior notes, due to mature on August 1, 2022. We received net proceeds in the offering of approximately $318.8 million, after discounts and offering expenses. Interest is payable semi-annually at a rate of 6.25% per annum on February 1 and August 1 of each year, with the first interest payment to be made on February 1, 2015. We used the proceeds of the offering to repay all of the borrowings outstanding under our Senior Credit Facility, which was $218.0 million at the time of the payment, and expect to use the remaining proceeds for general corporate purposes.

Operating revenue for the three and six months ended June 30, 2014 increased 55.4% and 77.6%, respectively, when compared to the same periods in 2013. The increase in operating revenue for the three and six-month periods ended June 30, 2014, can be

primarily attributed to higher production in both of our operating regions and increased sales prices for oil and NGLs during the three months ended June 30, 2014 and increased sales prices for oil, natural gas and NGLs during the six months ended June 30, 2014. In the Appalachian Basin, our production grew to 10,473 MMcfe for the three-month period ended June 30, 2014, from 6,688 MMcfe for the three-month period ended June 30, 2013, or approximately 56.6%, while realized sales prices have increased to $97.50 per barrel for oil and $46.98 per barrel for NGLs. In the Illinois Basin, our production increased to 208 MBbls for the three-month period ended June 30, 2014 from 191 MBbls for the three-month period ended June 30, 2013, or approximately 9.0%. For the six months ended June 30, 2014, production in the Appalachian Basin has increased 65.4% to 20,372 MMcfe from the same period in 2013, while production in the Illinois Basin for the six months ended June 30, 2014 increased 2.2% to 391 MBls from the same period in 2013. For the six-month period ended June 30, 2014, realized sales prices increased to $95.29 per barrel for oil, $4.58 per mcf for natural gas and $52.50 per barrel for NGLs. Also contributing to our increased revenue was the continued growth of our field services segment from $3.8 million in revenue for the quarter ended June 30, 2013 to $13.1 million in revenue for the quarter ended June 30, 2014. Increased activity and demand in the Appalachian Basin surrounding the Marcellus and Utica Shale plays have led to the growth of our field services activities, particularly water pipeline and water transfer to service well completion activities.

Operating expenses increased $22.5 million and $48.4 million for the three and six-month period ended June 30, 2014, respectively, as compared to the same periods in 2013. Operating expenses primarily comprise: Production and Lease Operating Expenses, G&A Expenses, Gain/Loss on Disposal of Assets, Exploration Expenses, Impairment Expense, DD&A Expenses and Field Operating Expenses. The increases in operating expenses were largely to Production and Lease Operating Expense, G&A Expense, DD&A and Field Service Operating Expense. The growth of these operating expenses is consistent with our overall organizational growth as we continue to increase our drilling and exploration activity and our number of revenue generating assets.

Comparison of the Three Months Ended June 30, 2014 to the Three Months Ended June 30, 2013

Oil, NGL and gas revenue, including the effects of cash settled derivatives, for the three-month periods ended June 30, 2014 and 2013 ($ in thousands, except total Mcfe production and price per Mcfe) is summarized in the following table:

	For Three Months Ended June 30,

Average Realized Price per Mcfe	$	6.05		$	6.71		$	(0.66	)		-9.8	%

Average realized price received for oil, NGLs and natural gas during the second quarter of 2014, after the effect of derivative activities, was $6.05 per Mcfe, a decrease of 9.8%, or $0.66 per Mcfe, from the same period in 2013. This decrease was primarily due to a decrease in realized natural gas sales prices and a net loss on the settlement of derivatives, partially offset by an upward trend of average realized oil and NGL prices. The average price for natural gas, after the effect of derivative activities, decreased 14.2%, or $0.64 per Mcf, to $3.84 per Mcf. The average price for oil and condensate, after the effect of derivative activities, increased 2.6%, or $2.35 per barrel, to $93.51 per barrel. The average price for C3+ NGLs, after the effect of derivative activities, increased 2.9%, or $1.36 per barrel, to $48.86 per barrel. During the second quarter of 2014, we commenced sales of ethane, which had previously been separated from our NGL stream and primarily burned as fuel with small amounts blended with our C3+ NGL sales. The average price for ethane during the three months ended June 30, 2014 was approximately $6.00 per barrel. Our derivative activities effectively decreased net realized prices by $0.17 per Mcfe in the second quarter of 2014 and effectively increased net realized prices by $0.14 per Mcfe in the second quarter of 2013.

Production volumes in the second quarter of 2014 increased 49.7% from the second quarter of 2013. Natural gas production increased approximately 49.8%, oil and condensate production increased approximately 17.8% and our NGL production increased approximately 86.0%. Our production continues to be positively impacted by strong drilling results in the Appalachian Basin.

Overall, our production for the three months ended June 30, 2014 averaged 128,791 Mcfe per day, of which 69.7% was attributable to natural gas, 12.9% to oil and condensate, 16.7% to C3+ NGLs and 0.7% was a result of ethane production.

Field Services Revenue for the three months ended June 30, 2014 increased approximately $9.2 million, as compared to the second quarter of 2013. We generate field services revenue from various field service activities such as the management of water sourcing, water transfer and water disposal activities in the Appalachian Basin. Increased activity and demand in the Appalachian Basin surrounding the Marcellus and Utica Shale plays have led to the growth of our field services activities, particularly water pipeline and water transfer to service well completion activities.

Production and Lease Operating Expense increased approximately $8.5 million, or 65.1%, in the second quarter of 2014 from the same period in 2013. We experienced Production and Lease Operating Expense increases that are commensurate with the increase in producing wells in the Appalachian Basin and related production as they relate to variable type costs such as transportation, marketing, processing and gathering. For the second quarter of 2014, transportation, capacity and processing fees accounted for approximately 51.2% of our total Production and Lease Operating Expense as compared to 38.9% in the second quarter of 2013. These types of agreements typically have a term of several years, and we expect fees associated with these agreements to continue to comprise a significant portion of our Production and Lease Operating Expense.

G&A Expense for the second quarter of 2014 increased approximately $1.5 million, or 18.7%, to $9.2 million from the same period in 2013. The year-over-year increase is predominately due to the expansion of our Appalachian Basin operations and our corporate headquarters that is commensurate with our overall organizational growth.

Exploration Expense for the three months ended June 30, 2014 was approximately $1.4 million, as compared to $2.2 million for the three months ended June 30, 2013. Approximately $0.9 million of the expense incurred in 2014 was due to geological and geophysical type expenditures. An additional $0.4 million of expense was incurred through the payment of delay rentals, predominately in the Appalachian Basin. Approximately $1.3 million of the expense incurred in 2013 was due to geological and geophysical type

expenditures and delay rentals in the Appalachian Basin and $0.9 million was due to geological and geophysical type expenditures and dry hole expense in the Illinois Basin.

DD&A expenses for the three months ended June 30, 2014 increased approximately $8.3 million, or 64.0%, from $12.9 million for the same period in 2013. The period-over-period increase in DD&A expense is consistent with the growth in our asset base, reserves and production since the comparable period of 2013.

Field Service Operating Expense for the three months ended June 30, 2014 totaled approximately $9.6 million, as compared to $2.6 million for the same period 2013. Our field services operating expenses are largely variable in nature and fluctuate commensurate with our level of activity. Increased activity and demand in the Appalachian Basin surrounding the Marcellus and Utica Shale plays has led to the growth of our field service activities, particularly those associated with water pipeline construction and water transfer for well completion operations.

Interest Expense for the three months ended June 30, 2014 was approximately $7.5 million as compared to $5.8 million during the second quarter of 2013. The increase in interest expense was due to the increase in the outstanding balance of our Senior Credit Facility compared to the same period in 2013.

Gain (Loss) on Derivatives, net included a loss of approximately $0.3 million for the second quarter of 2014 as compared to a gain of $11.7 million for the same period in 2013. Changes were attributable to the volatility of oil, NGL and gas commodity prices along with changes in our portfolio of outstanding derivatives. Losses from derivative activities generally reflect higher oil, NGL and gas prices in the marketplace than were in effect at the end of the last period while gains generally reflect the opposite. Our derivative program is designed to provide us with greater reliability of future cash flows at expected levels of oil, NGL and gas production volumes given the highly volatile oil, NGL and gas commodities market.

Income Tax Expense was approximately $5.9 million for the three months ended June 30, 2014, as compared to $9.1 million for the three months ended June 30, 2013. In addition to the variance in Income from Continuing Operations, Before Income Tax, the change was primarily due to a change in the estimated effective state tax rate driven by our increased activities in the state of Ohio.

Net Income Attributable to Rex Energy for the second quarter of 2014 was approximately $8.1 million, as compared $13.7 million for the comparable period in 2013 as a result of the factors discussed above.

Comparison of the Six Months Ended June 30, 2014 to the Six Months Ended June 30, 2013

Oil, NGL and gas revenue, including the effects of cash settled derivatives, for the six-month periods ended June 30, 2014 and 2013 ($ in thousands, except total Mcfe production and price per Mcfe) is summarized in the following table:

Average realized price received for oil, NGLs and natural gas during the first six months of 2014, after the effect of derivative activities, was $6.47 per Mcfe, a decrease of 2.7%, or $0.18 per Mcfe, from the same period in 2013. This decrease was primarily due to net losses on the settlement of derivatives which were partially offset by an upward trend of average realized oil, natural gas and

NGL prices. The average price for natural gas, after the effect of derivative activities, decreased 1.8%, or $0.08 per Mcf, to $4.31 per Mcf. The average price for oil and condensate, after the effect of derivative activities, increased 1.7%, or $1.51 per barrel, to $92.45 per barrel. The average price for C3+ NGLs, after the effect of derivative activities, increased 9.4%, or $4.39 per barrel, to $51.23 per barrel. During the second quarter of 2014 we commenced sales of ethane, which had previously been separated from our NGL stream and primarily burned as fuel with small amounts blended with our C3+ NGL sales. The average price for ethane during the three months ended June 30, 2014 was approximately $6.00 per barrel. Our derivative activities effectively decreased net realized prices by $0.32 per Mcfe in the first half of 2014 and effectively increased net realized prices by $0.33 per Mcfe in the first half of 2013.

In the first half of 2014, our realized natural gas prices were higher than the Henry Hub average for the period. During the first quarter of 2014, we were exposed to M3 pricing, a New York area index, on the Texas Eastern pipeline which increased as a result of demand created during the colder winter months.

Production volumes in the first six months of 2014 increased 55.5% from the same period in 2013. Natural gas production increased approximately 54.6%, oil and condensate production increased approximately 22.0% and our NGL production increased approximately 103.9%. Our production continues to be positively impacted by strong drilling results in the Appalachian Basin.

Overall, our production for the six months ended June 30, 2014 averaged 125,506 Mcfe per day, of which 69.7% was attributable to natural gas, 13.3% to oil, 16.7% to C3+ NGLs and 0.4% was a result of ethane production.

Field Services Revenue for the six months ended June 30, 2014 increased approximately $18.0 million, as compared to the first six months of 2013. We generate field services revenue from various field service activities such as the management of water sourcing, water transfer and water disposal activities in the Appalachian Basin. Increased activity and demand in the Appalachian Basin surrounding the Marcellus and Utica Shale plays have led to the growth of our field services activities, particularly water pipeline and water transfer to service well completion activities.

Production and Lease Operating Expense increased approximately $15.1 million, or 57.2%, in the first half of 2014 from the same period in 2013. We experienced Production and Lease Operating Expense increases that are commensurate with the increase in producing wells in the Appalachian Basin and related production as they relate to variable type costs such as transportation, marketing, processing and gathering. For the six months ended June 30, 2014, transportation, capacity and processing fees accounted

for approximately 49.1% of our total Production and Lease Operating Expense as compared to 37.7% in the first half of 2013. These types of agreements typically have a term of several years, and we expect fees associated with these agreements to continue to comprise a significant portion of our Production and Lease Operating Expense.

G&A Expense for the first half of 2014 increased approximately $4.1 million, or 26.0%, to $19.6 million from the same period in 2013. The year-over-year increase is predominately due to the expansion of our Appalachian Basin operations and our corporate headquarters that is commensurate with our overall organizational growth.

Exploration Expense for the six months ended June 30, 2014 was approximately $3.4 million, as compared to $4.3 million for the same period in 2013. Approximately $2.2 million of the expense incurred in 2014 was due to geological and geophysical type expenditures and delay rentals in the Appalachian Basin and $1.1 million was due to geological and geophysical type expenditures in the Illinois Basin. Approximately $2.7 million of the expense incurred in 2013 was due to geological and geophysical type expenditures and delay rentals in the Appalachian Basin and $1.6 million was due to geological and geophysical type expenditures and dry hole expense in the Illinois Basin.

DD&A expenses for the six months ended June 30, 2014 increased approximately $17.5 million, or 72.8%, from $24.1 million for the same period in 2013. The period-over-period increase in DD&A expense is consistent with the growth in our asset base, reserves and production since the comparable period of 2013.

Field Service Operating Expense for the six months ended June 30, 2014 totaled approximately $21.4 million, as compared to $6.7 million for the same period 2013. Our field services operating expenses are largely variable in nature and fluctuate commensurate with our level of activity. Increased activity and demand in the Appalachian Basin surrounding the Marcellus and Utica Shale plays has led to the growth of our field service activities, particularly those associated with water pipeline construction and water transfer for well completion operations. As compared to the first six months of 2013, we have experienced declining gross margins in our field services business primarily due to the diversification of our business, which has included new lower margin service offerings such as pipeline construction and water hauling.

Interest Expense for the six months ended June 30, 2014 was approximately $14.6 million, as compared to $9.8 million during the first quarter of 2013. The increase in interest expense was due to our issuance of an additional $100.0 million of Senior Notes in April 2013 and the increase in the outstanding balance of our Senior Credit Facility in 2014.

Gain (Loss) on Derivatives, net included a loss of approximately $10.0 million for the first half of 2014 as compared to a gain of $3.2 million for the same period in 2013. Changes were attributable to the volatility of oil, NGL and gas commodity prices along with changes in our portfolio of outstanding derivatives. Losses from derivative activities generally reflect higher oil, NGL and gas prices in the marketplace than were in effect at the end of the last period while gains generally reflect the opposite. Our derivative program is designed to provide us with greater reliability of future cash flows at expected levels of oil, NGL and gas production volumes given the highly volatile oil, NGL and gas commodities market.

Income Tax Expense was approximately $10.1 million for the six months ended June 30, 2014 as compared to $7.1 million for the six months ended June 30, 2013. In addition to the variance in Income from Continuing Operations, Before Income Tax, the change was primarily due to a change in the estimated effective state tax rate driven by our increased activities in the state of Ohio.

Net Income Attributable to Rex Energy for the first half of 2014 was approximately $16.9 million, as compared to $10.9 million for the comparable period in 2013, as a result of the factors discussed above.

EBITDAX (Non-GAAP) from continuing operations increased approximately $10.8 million to $44.0 million for the three-month period ended June 30, 2014, as compared to the same period in 2013. EBITDAX from continuing operations increased approximately $33.8 million to $93.1 million for the six-month period ended June 30, 2014, as compared to the same period in 2013. The increase in EBITDAX can be primarily attributed to higher production and higher average sales prices for oil, natural gas and

NGLs for the six-month period ended June 30, 2014 and higher average sales prices for oil and NGLs for the three-month period ended June 30, 2014, resulting in increased operating revenues. These increases were partially offset by an increase in operating expenses and settlements on derivatives. See “Non-GAAP Financial Measures” for our reconciliation of EBITDAX to net income.

LOE per Mcfe measures the average cost of extracting oil, NGLs and natural gas from our basin reserves during the period. This measurement is also commonly referred to in the industry as our “lifting cost”. It represents the average cost of extracting one Mcf of natural gas equivalent from our oil, NGL and natural gas reserves in the ground. LOE per Mcfe increased to $1.84 for the three months ended June 30, 2014 as compared to $1.67 for the same period in 2013. LOE per Mcfe increased to $1.83 for the six months ended June 30, 2014 as compared to $1.81 for the same period in 2013. Our LOE is largely comprised of variable type costs such as transportation, marketing, processing and gathering. For the first half of 2014, transportation, capacity and processing fees accounted for approximately 49.1% of our total Production and Lease Operating Expense as compared to 37.7% in the first half of 2013. These agreements typically have a term of several years, and we expect them to continue to comprise a significant portion of our Production and Lease Operating Expense. Various agreements that we have entered include firm capacity rights, for which we may incur a fee for unused capacity. As we continue to grow our operations, particularly those in the Appalachian Basin, which have lower operating costs, we expect our lifting cost to decrease as we gain additional efficiencies of scale and utilize all of our firm capacity and transportation commitments.

Our G&A expenses include fees for well operating services, marketing, non-field level employee compensation and related benefits, office and lease expenses, insurance costs and professional fees, as well as other costs and expenses not directly related to field operations. Our management continually evaluates the level of our G&A expenses in relation to our production because these expenses have a direct impact on our profitability. G&A expenses per Mcfe decreased to approximately $0.79 for the three-month period ended June 30, 2014, as compared to $0.99 for the same period in 2013. G&A expenses per Mcfe decreased to approximately $0.86 for the six-month period ended June 30, 2014, as compared to $1.07 for the same period in 2013. The year-over-year decrease is predominately due to our production growth, particularly in the Appalachian Basin, which was partially offset by an increase in expenses that is commensurate with our overall organizational growth.

Our primary needs for cash are for the exploration, development and acquisition of oil and gas properties. During the six months ended June 30, 2014, we spent $225.7 million of capital on drilling projects, facilities and related equipment and acquisitions of unproved acreage. We funded our capital program with net cash flows from operations and net proceeds from our Senior Credit Facility. The remainder of our 2014 capital budget of $164.4 million to $179.4 million is expected to be funded primarily by cash on hand, cash flow from operations and borrowings under our Senior Credit Facility, of which approximately $173.0 million was available at June 30, 2014. On July 14, 2014, we issued $325.0 million in aggregate principal amount of 6.25% senior notes. We used the proceeds of this offering to repay all of the borrowings outstanding under our Senior Credit Facility, which was $218.0 million at the time of repayment. In connection with the offering of the notes, our borrowing base was automatically reduced by 25% of the principal amount of the notes to $293.8 million, all of which was available subsequent to the offering of the notes. The amounts remaining under our original 2014 capital budget do not contemplate expenditures related to capital interest or acquisitions of unproved acreage. We currently believe we have sufficient liquidity and cash flow to meet our obligations for the next twelve months; however, a significant drop in commodity prices, particularly natural gas, or reduction in production or reserves could adversely affect our ability to fund capital expenditures and meet our financial obligations. Also, our obligations may change due to acquisitions, divestitures and continued growth. We may also elect to issue additional shares of stock, subordinated notes or other securities or sell non-core assets to fund capital expenditures, acquisitions, extend maturities or to repay debt.

Our ability to fund our capital expenditure program is dependent upon the level of commodity prices and the success of our exploration programs in replacing our existing oil, NGL and gas reserves. If commodity prices decrease, our operating cash flows may decrease and the banks may require additional collateral or reduce our borrowing base, thus reducing funds available to fund our capital expenditure program. The effects of commodity prices on cash flows can be mitigated through the use of commodity derivatives. If we are unable to replace our oil, NGL and gas reserves through our acquisitions, development and exploration programs, we may also suffer a reduction in our operating cash flows and access to funds under the Senior Credit Facility. Under extreme circumstances, commodity price reductions or exploration drilling failures could allow the banks to seek to foreclose on our oil and gas properties, thereby threatening our financial viability.

Our cash flows from operations are driven by commodity prices and production volumes. Prices for oil, NGLs and gas are driven by, among other things, seasonal influences of weather, national and international economic and political environments and, increasingly, from heightened demand for hydrocarbons from emerging nations. Our working capital is significantly influenced by

changes in commodity prices, and significant declines in prices could decrease our exploration and development expenditures. Historically, cash flows from operations, borrowings from our Senior Credit Facility and net proceeds from debt and equity offerings have been primarily used to fund exploration and development of our oil and gas interests.

We are not restricted as to our borrowings under the Senior Credit Facility; however we are subject to the minimum financial requirements detailed in Note 8, Long-Term Debt, to our Consolidated Financial Statements.

In connection with certain marketing, transportation and processing agreements that we have entered into, we may be obligated to pay fees in connection with these agreements of $149.6 million over the next five years, depending on our levels of production. Also in connection with certain of these agreements, we have guaranteed the payment of obligations up to a maximum of $406.2 million over the life of the agreements.

Financial Condition and Cash Flows for the Six Months Ended June 30, 2014 and 2013

The following table summarizes our sources and uses of funds for the periods noted:

Net cash provided by operating activities increased by approximately $25.6 million in the first six months of 2014 over the same period in 2013. Strong production and commodity prices during the first half of 2014 resulted in increased cash flows from operations, which were offset by a reduction in working capital and settlements of derivatives. This offsetting decrease during the first six months of 2014 was primarily driven by an increase in our Accounts Receivable due to our growth in production and revenue and net cash payments on derivatives of $6.3 million in 2014 as compared to net cash receipts on derivatives of $4.8 million.

Net cash used in investing activities increased by approximately $87.7 million from the first six months of 2013 to $225.4 million in the first six months of 2014. This change can be primarily attributed to increased drilling and completion activity and acreage acquisitions in 2014 as compared to 2013.

Net cash provided by financing activities increased by approximately $41.0 million for the first six months of 2014 to $142.9 million from $101.9 million for the first six months of 2013. The increase was primarily due to net borrowings on Senior Credit Facility during the first half of 2014 of $144.7 million as compared to proceeds from our Senior Notes of $105.0 million in 2013.

Our results of operations and cash flows are affected by changing oil, NGL and natural gas prices. If the price of oil, NGLs and natural gas increases or decreases, there could be a corresponding increase or decrease in the operating cost that we are required to bear for operations, as well as an increase or decrease in revenues.

During the quarter ended June 30, 2014, there were no material changes to the critical accounting policies previously reported by us in our Annual Report on Form 10-K for the year ended December 31, 2013. We describe critical recently adopted and issued accounting standards in Item 1. Financial Statements—Note 6, “Recently Issued Accounting Pronouncements.”

“EBITDAX” means, for any period, the sum of net income for such period plus the following expenses, charges or income to the extent deducted from or added to net income in such period: interest, income taxes, DD&A, unrealized losses from financial derivatives, exploration expenses and other similar non-cash charges, minus all non-cash income, including but not limited to, income from unrealized financial derivatives, added to net income. EBITDAX, as defined above, is used as a financial measure by our management team and by other users of its financial statements, such as our commercial bank lenders to analyze such things as:

EBITDAX is not a calculation based on GAAP financial measures and should not be considered as an alternative to net income (loss) (the most directly comparable GAAP financial measure) in measuring our performance, nor should it be used as an exclusive measure of cash flows, because it does not consider the impact of working capital growth, capital expenditures, debt principal reductions, and other sources and uses of cash, which are disclosed in our consolidated statements of cash flows.

We have reported EBITDAX because it is a financial measure used by our existing commercial lenders, and because this measure is commonly reported and widely used by investors as an indicator of a company’s operating performance and ability to incur and service debt. You should carefully consider the specific items included in our computations of EBITDAX. While we have disclosed EBITDAX to permit a more complete comparative analysis of our operating performance and debt servicing ability relative to other companies, you are cautioned that EBITDAX as reported by us may not be comparable in all instances to EBITDAX as reported by other companies. EBITDAX amounts may not be fully available for management’s discretionary use, due to requirements to conserve funds for capital expenditures, debt service and other commitments.

We believe that EBITDAX assists our lenders and investors in comparing our performance on a consistent basis without regard to certain expenses, which can vary significantly depending upon accounting methods. Because we may borrow money to finance our operations, interest expense is a necessary element of our costs. In addition, because we use capital assets, DD&A are also necessary elements of our costs. Finally, we are required to pay federal and state taxes, which are necessary elements of our costs. Therefore, any measures that exclude these elements have material limitations.

To compensate for these limitations, we believe it is important to consider both net income determined under GAAP and EBITDAX to evaluate our performance.

The following table presents a reconciliation of our net income to EBITDAX for each of the periods presented ($ in thousands):

Our revenues, future rate of growth, results of operations, financial condition and ability to borrow funds or obtain additional capital, as well as the carrying value of our properties, are substantially dependent upon prevailing prices of oil, NGLs and natural gas.

We account for our natural gas and oil exploration and production activities under the successful efforts method of accounting. To mitigate some of our commodity price risk, we engage periodically in certain other limited derivative activities including price swaps and costless collars in order to establish some price floor protection.

For the three and six months ended June 30, 2014, we paid net settlements on oil, NGL and natural gas derivatives of approximately $2.0 million and 7.2 million, respectively, as compared to net receipts of approximately $1.1 million and $4.8 million for the comparable period in 2013, respectively. These gains and losses are reported as Gain (Loss) on Derivatives, Net in our Consolidated Statements of Operations. As of June 30, 2014, we had over 90% of our annualized 2014 oil production hedged through the remainder of 2014, over 80% and 40% of our annualized 2014 natural gas production hedged through the remainder of 2014 and 2015, and over 70% of our annualized 2014 NGL production hedged through the remainder of 2014, respectively. These percentages exclude the effects of our basis swaps and do not include any estimated impact of increased production from future drilling and completion activity or the natural decline of our oil and gas production.

While the use of derivative arrangements limits the downside risk of adverse price movements, it may also limit our ability to benefit from increases in the prices of oil, NGLs and natural gas. We enter into all of our derivatives transactions with five counterparties and have a netting agreement in place with our counterparties. While we do not obtain collateral to support the agreements, we do monitor the financial viability of our counterparties and believe our credit risk is minimal on these transactions. Under these arrangements, payments are received or made based on the differential between a fixed and a variable commodity price. These agreements are settled in cash at expiration or exchanged for physical delivery contracts. In the event of nonperformance, we would be exposed again to price risk. We have additional risk of financial loss because the price received for the product at the actual physical delivery point may differ from the prevailing price at the delivery point required for settlement of the derivative transaction. Moreover, our derivatives arrangements generally do not apply to all of our production and thus provide only partial price protection against declines in commodity prices. We expect that the amount of our derivatives will vary from time to time.

For a summary of our current oil, NGL and natural gas derivative positions at June 30, 2014, refer to Item 1. Financial Statements—Note 9, “Fair Value of Financial and Derivative Instruments”.

In addition to our capital expenditure program, we are committed to making cash payments in the future on various types of contracts and obligations. Our contractual obligations include long-term debt, operating leases, other loans and notes payable, derivative obligations, firm commitments under sales, gathering and processing agreements and asset retirement obligations. Since December 31, 2013, there have been no material changes to our contractual obligations, other than an increase in long-term debt due to our borrowings under the Senior Credit Facility. See Item 1. Financial Statements—Note 8, “Long-Term Debt” for additional information on the Senior Credit Facility.

We do not currently use any off-balance sheet arrangements to enhance our liquidity or capital resource position, or for any other purpose.

We are exposed to various market risks, including energy commodity price risk. We expect energy prices to remain volatile and unpredictable. If energy prices were to decrease for a substantial period of time or decline significantly, revenues and cash flows would significantly decline, and our ability to borrow to finance our operations could be adversely impacted. Our financial condition, results of operations and capital resources are highly dependent upon the prevailing market prices of, and demand for, oil, NGLs and natural gas. Conversely, increases in the market prices for oil, NGLs and natural gas can have a favorable impact on our financial condition, results of operations and capital resources. Based on production through June 30, 2014, we project that a 10% decline in the price per barrel of oil and NGLs and the price per Mcf of gas from the first six months of the 2014 average would reduce our gross revenues, before the effects of derivatives, for the remaining six months of 2014 by approximately $15.4 million.

We have designed our hedging program to reduce the risk of price volatility for our production in the oil, NGL and natural gas markets. Our risk management policy provides for the use of derivative instruments to manage these risks. The types of derivative instruments that we use include swaps, collars, put spreads, put options, basis swaps, swaptions and three way collars. The volume of derivative instruments that we may use are governed by the risk management policy and can vary from year to year, but under most circumstances will apply to only a portion of our current and anticipated production, and will provide only partial price protection against declines in oil, NGL and natural gas prices. We are exposed to market risk on our open contracts, to the extent of changes in market prices of oil, NGLs and natural gas. However, the market risk exposure on these hedged contracts is generally offset by the

gain or loss recognized upon the ultimate sale of the commodity that is hedged. Further, if our counterparties should default, this protection might be limited as we might not receive the benefits of the hedges.

At June 30, 2014, we had the following commodity derivative contracts outstanding:

We are also exposed to market risk related to adverse changes in interest rates. Our interest rate risk exposure results primarily from fluctuations in short-term rates, which are LIBOR and prime rate based, as determined by our lenders, and may result in reductions of earnings or cash flows due to increases in the interest rates we pay on our obligations. In the past, we have used an interest rate swap agreement to manage risk associated with interest payments on amounts outstanding from variable rate borrowing under our Senior Credit Facility; however, during the three months ended June 30, 2014, we terminated our interest rate swap for net proceeds of approximately $0.6 million. During the three and six months ended June 30, 2014, we received cash payments of approximately $0.5 million and $0.9 million, respectively, related to our interest rate swaps. Based on our total debt as of June 30, 2014 of approximately $564.6 million, a 1.0% change in interest rates would impact our interest expense by approximately $5.6 million.

We maintain disclosure controls and procedures that are designed to ensure that that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. Such controls include those designed to ensure that information required to be disclosed by us in the reports that we file under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), to allow timely decisions regarding required disclosure.

Our management (with the participation of our CEO and CFO) has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this report. Based on this evaluation, our CEO and CFO have concluded that, as of June 30, 2014, our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and

communicated to management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) promulgated under the Exchange Act) during the quarter ended June 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Our management, including our CEO and CFO, recognizes that the disclosure controls and procedures and internal controls (discussed above) cannot prevent all errors or all attempts at fraud. Any controls system, no matter how well-crafted and operated, can only provide reasonable, and not absolute, assurance of achieving the desired control objectives. Because of the inherent limitations in any control system, no evaluation or implementation of a control system can provide complete assurance that all control issues and all possible instances of fraud have been, or will be, detected.

The information set forth under the subsections Legal Reserves and Environmental in Note 13, Commitments and Contingencies, to our Consolidated Financial Statements included in Item 1 of Part 1 of this report is incorporated herein by reference.

During the quarter ended June 30, 2014, there were no material changes to the risk factors previously reported in our Annual Report on Form 10-K for the year ended December 31, 2013.

The information required by this Item 6 is set forth in the Index to Exhibits accompanying this Form 10-Q and incorporated herein by reference.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this Report to be signed on its behalf by the undersigned thereunto duly authorized.
