Section 3.11                             Books and Records; Sarbanes-Oxley Compliance.

(a)                       Each of the Triangle Entities (i) makes and keeps accurate books and records and (ii) maintains and has maintained effective internal control over financial reporting (as defined in Rule 13a-15 under the Exchange Act) and a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations, (B) transactions are recorded as necessary to permit preparation of Triangle’s consolidated financial statements in conformity with GAAP and to maintain accountability for its assets, (C) access to the Triangle Entities’ assets is permitted only in accordance with management’s general or specific authorization and (D) the recorded accountability for the Triangle Entities’ assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Triangle is not aware of any failures of such internal accounting controls that are material or that would be required to be disclosed pursuant to any applicable Law.

(b)                       Triangle has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 under the Exchange Act), such disclosure controls and procedures are designed to ensure that the information required to be disclosed by Triangle in the reports it files or submits under the Exchange Act is accumulated and communicated to management of Triangle, including its principal executive officers and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure to be made and such disclosure controls and procedures are effective in alerting Triangle in a timely manner to material information required to be disclosed in Triangle’s reports filed with the Commission.

(c)                        To the Knowledge of Triangle, there is and has been no failure on the part of Triangle or any of Triangle’s directors or officers, in their capacities as such, to comply in all material respects with the provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith.

Section 3.12                             No Material Adverse Change.  Except as described on Schedule 3.12, since January 31, 2013, there has not been (i) any change, development, condition, circumstance, occurrence or event that has had or is reasonably likely to have a Triangle Material Adverse Effect, (ii) any transaction that is material to the Triangle Entities taken as a whole, (iii) any obligation or liability, direct or contingent (including any off-balance sheet obligations), incurred by any of the Triangle Entities that is material to the Triangle Entities taken as a whole,

(iv) any change in the capital stock, membership or other equity interests or outstanding indebtedness of any of the Triangle Entities that is material to the Triangle Entities taken as a whole, (v) any dividend or distribution of any kind declared, paid or made on the capital stock of Triangle or (vi) any material change in Triangle’s accounting or tax principles, practices or methods.

Section 3.13                             Title to Property.

(a)                       Except as described on Schedule 3.13, other than to the extent such would not, individually or in the aggregate, reasonably be expected to have a Triangle Material Adverse Effect, each of the Triangle Entities has good and marketable title to all real property (other than oil and gas properties) and personal property owned by them and valid, legal and defensible title to the interests in oil and gas properties underlying the estimates of the Triangle Entities’ proved reserves set forth in Triangle’s most recently-filed Form 10-K, as amended, in each case free and clear of all Liens except (i) Liens arising under or securing indebtedness incurred under the Triangle Credit Agreement or the RockPile Credit Agreement or (ii) Liens that do not materially affect the value of such properties taken as a whole.

(b)                       Other than to the extent such would not, individually or in the aggregate, reasonably be expected to have a Triangle Material Adverse Effect, all real property and buildings held under lease by the Triangle Entities are held by them under valid, subsisting and enforceable leases, and the working interests derived from oil, gas and mineral leases or mineral interests held or leased by the Triangle Entities give the Triangle Entities the right to explore, develop and produce hydrocarbons from such properties consistent with standard industry practices.  The care taken by the Triangle Entities with respect to acquiring or otherwise procuring such leases or mineral interests was generally consistent with standard industry practices in the areas in which the Triangle Entities operate for acquiring or procuring leases and mineral interests therein to explore, develop and produce hydrocarbons. No real property (including oil, gas and mineral leases and mineral interests) owned, leased, licensed or used by the Triangle Entities lies in an area which is, or to the Knowledge of the Triangle Entities will be, subject to restrictions which would prohibit, and no statements of facts relating to the actions or inaction of another Person or its ownership, leasing, licensing, or use of any real or personal property (including oil, gas and mineral leases and mineral interests) exists or will exist which would prevent, the continued effective ownership, leasing, licensing, exploration, development or production or use of such property in the business of the Triangle Entities as presently conducted or as the Triangle SEC Documents indicate they contemplate conducting.

(c)                        As of the date hereof, (i) all royalties, rentals, deposits and other amounts owed under the oil and gas leases constituting the oil and gas properties of the Triangle Entities have been properly and timely paid (other than amounts held in suspense accounts pending routine payments or related to disputes about the proper identification of royalty owners), and no material amount of proceeds from the sale or production attributable to the oil and gas properties of the Triangle Entities are currently being held in suspense by any purchaser thereof, and (ii) there are no claims under take-or-pay contracts pursuant to which natural gas purchasers have any make-up rights affecting the interests of the Triangle Entities in their oil and

16

gas properties, except in each case where such failure to pay or claim would not, individually or in the aggregate, be reasonably likely to have a Triangle Material Adverse Effect.

Section 3.14                             Reserve Engineers; Reserve Estimates.

(a)                       Cawley, Gillespie & Associates, Inc., who issued a report with respect to the Triangle Entities’ oil and natural gas reserves at January 31, 2013, has represented to Triangle that it is, and to the Knowledge of Triangle is, an independent petroleum engineer with respect to Triangle.

(b)                       The oil and gas reserve estimates of the Triangle Entities included in Triangle’s most recently-filed Form 10-K, as amended, have been prepared by independent reserve engineers in accordance with Commission guidelines applied on a consistent basis throughout the periods involved, and Triangle has no reason to believe that such estimates do not fairly reflect the oil and gas reserves of the Triangle Entities as of the dates indicated.  Other than normal production of the reserves and intervening market commodity price fluctuations, and except as described in Triangle’s most recently-filed Form 10-K, as amended, Triangle is not aware of any facts or circumstances that would result in a material adverse change in the aggregate net reserves, or the aggregate present value of future net cash flows therefrom, as described in Triangle’s most recently-filed Form 10-K, as amended.

Section 3.15                             Insurance.  The Triangle Entities are insured by insurers in such amounts as Triangle believes are adequate for the conduct of their business and as Triangle believes are customary for the business in which they are engaged.  All such policies of insurance insuring the Triangle Entities are in full force and effect and the Triangle Entities have no reason to believe that any of them will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business. There are no material claims by any of the Triangle Entities under any such policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause.

Section 3.16                             Litigation.  Except as described on Schedule 3.16, there are no actions, suits, claims, investigations or proceedings pending or, to the Knowledge of Triangle, threatened, to which any of the Triangle Entities is or would be a party or of which any of their respective properties or assets is or would be subject at Law or in equity, before or by any Governmental Authority, or before or by any self-regulatory organization or other non-governmental regulatory authority (including NYSE MKT), which are reasonably likely to, individually or in the aggregate, have a Triangle Material Adverse Effect.

Section 3.17                             Labor, Employment and Benefit Matters.

(a)                       None of the Triangle Entities have agreed to recognize any union or other collective bargaining representative, and no union or other collective bargaining representative has been certified as the exclusive bargaining representative of any of their employees.  To the Knowledge of Triangle, no union organizational campaign or representation

petition is currently pending with respect to any of the employees of the Triangle Entities.  None of the Triangle Entities are party to or bound by any collective bargaining agreement or labor contract or individual agreement applicable to any employees of the Triangle Entities.  No collective bargaining agreements or other labor contract relating to employees of the Triangle Entities are being negotiated.  Except for such exceptions as would not, individually or in the aggregate, reasonably be expected to have a Triangle Material Adverse Effect, none of the Triangle Entities are subject to any consent decree with any Governmental Authority or arbitrator relating to claims of unfair labor practices, employment discrimination, or other claims with respect to employment and labor practices and policies, and no Government Authority or arbitrator has issued a judgment, order, decree, injunction, decision, award or finding with respect to the employment and labor practices or policies of the Triangle Entities. No labor dispute with the employees of the Triangle Entities exists or, to the Knowledge of Triangle, is imminent, and Triangle is not aware of any existing or imminent labor disturbance by the employees of any of the Triangle Entities’ principal operators, contractors, suppliers or customers, which, in any such case would, individually or in the aggregate, reasonably be likely to have a Triangle Material Adverse Effect.  To the Knowledge of Triangle, no executive officer of Triangle presently plans to terminate his or her employment.

(b)                       Each Plan has been established, administered and operated in compliance with its terms and all applicable Laws, including without limitation the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the Internal Revenue Code of 1986, as amended (the “Code”), except where the failure to so comply would not, individually or in the aggregate, be reasonably likely to have a Triangle Material Adverse Effect.  Each Plan intended to be qualified under section 401(a) of the Code (i) is maintained pursuant to a prototype document approved by the Internal Revenue Service, for which a separate determination letter is not required, or has received a favorable determination letter from the Internal Revenue Service regarding such qualified status, and (ii) has not been operated in a way that would reasonably be expected to adversely affect its qualified status.  No Plan is, and none of Triangle, the Triangle Subsidiaries or any ERISA Affiliate has any liability with respect to, a multiemployer plan (within the meaning of section 3(37) of ERISA) or a plan subject to Title IV of ERISA, Section 302 of ERISA or Section 412 of the Code.  No Plan provides or promises to provide retiree medical, dental or life insurance benefits to any current or former employee of Triangle or any Triangle Subsidiary (except to the extent required pursuant to Section 4980B(f) of the Code and the corresponding provisions of ERISA).  As used herein: (1) the term “Plan” means each of the following that is sponsored, maintained or contributed to by Triangle, any Triangle Subsidiary or any ERISA Affiliate, or with respect to which any of such entities could have any liability: (A) each “employee benefit plan,” as such term is defined in section 3(3) of ERISA (including employee benefit plans, such as foreign plans, which are not subject to the provisions of ERISA); and (B) each bonus, equity ownership, equity option, phantom equity, deferred compensation, incentive compensation, vacation, holiday, sick leave, and each other employee benefit plan, agreement, program, practice or understanding which is not described in clause (A); and (2) the term “ERISA Affiliate” means any entity, trade or business that is a member of a group described in Section 414(b), (c), (m) or (o) of the Code or Section 4001(b)(l) of ERISA that includes Triangle or any Triangle Subsidiary, or that is a member of the same

18

“controlled group” as Triangle or any Triangle Subsidiary pursuant to Section 4001(a)(14) of ERISA.

(c)                        All employees and former employees of the Triangle Entities have been paid in full all accrued and due wages, salaries, commissions, bonuses, vacation pay, severance and termination pay, sick pay, and other accrued and due compensation for all services performed by them up to the date hereof.  Except for such exceptions as would not, individually or in the aggregate, reasonably be expected to have a Triangle Material Adverse Effect, the Triangle Entities have, and have always been since February 1, 2010, in compliance with all applicable laws and regulations regarding labor and employment practices.

Section 3.18                             Tax Returns.

None of the Triangle Entities has entered into any transaction that, as of the date of this Agreement, has been identified by the Internal Revenue Service in published guidance as a “listed transaction” as defined under Section 1.6011-4(b)(2) of the Treasury Regulations promulgated under the Code.

(b)                       As used in this Agreement, (i) “Taxes” means any and all domestic or foreign, federal, state, local or other taxes of any kind (together with any and all interest, penalties, additions to tax and additional amounts imposed with respect thereto) imposed by any Governmental Authority, including taxes on or with respect to income, franchises, windfall or other profits, gross receipts, property, sales, use, capital stock, payroll, employment, unemployment, social security, workers’ compensation or net worth, and taxes in the nature of excise, withholding, ad valorem or value added, and including any liability in respect of any items described above as a transferee or successor, pursuant to Section 1.1502-6 of the Treasury Regulations (or any similar provision of state, local or foreign Law), or as an indemnitor, guarantor, surety or in a similar capacity under any Contract, and (ii) “Tax Return” means any return, report or similar filing (including the attached schedules) filed or required to be filed with respect to Taxes (and any amendments thereto), including any information return, claim for refund or declaration of estimated Taxes.

Section 6.02                             Indemnification by the Purchaser.  The Purchaser agrees to indemnify Triangle and its Representatives (collectively, “Triangle Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection

26

therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects as of the date hereof or as of the Closing or (ii) the breach of any of the covenants of the Purchaser contained herein; provided, that in the case of the immediately preceding clause (i), such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Triangle Related Party shall have given notice to the Purchaser shall constitute the date upon which such claim has been made; provided, further, that, absent fraud or willful misconduct, the liability of the Purchaser shall not be greater in amount than the Purchase Price.

Section 6.03                             Indemnification Procedure.

(a)                                 A claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification that it may claim in accordance with this Article VI.

(b)                                 Promptly after any Triangle Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (each, a “Third Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third Party Claim but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is prejudiced by such failure.  Such notice shall state the nature and the basis of such Third Party Claim to the extent then known.  The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith.  If the Indemnifying Party undertakes to defend or settle such Third Party Claim, it shall promptly, and in no event later than five (5) days following receipt of notice of such Third Party Claim, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof.  Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party.  After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to

27

participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a Third Party Claim, failed (y) to assume the defense or settlement of such Third Party Claim and employ counsel and (z) to notify the Indemnified Party of such assumption, or (B) the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such settlement or legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred; provided, however, that the Indemnifying Party shall not be responsible for the fees and expenses of more than one separate counsel for the Purchaser and its Affiliates.  Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrongdoing by, the Indemnified Party.

Section 6.04                             Tax Matters.  All indemnification payments under this Article VI shall be adjustments to the Purchase Price, except as otherwise required by applicable Law.

Section 6.05                             Exclusive Remedy.  Except for the assertion of any claim based on fraud, the remedies provided in this Article VI shall be the sole and exclusive legal remedies of the Parties, from and after the Closing and prior to the expiration of the applicable survival period in Section 7.04, with respect to breaches of representations, warranties and covenants under this Agreement and the transactions contemplated hereby.

ARTICLE VII

32

Securities Act or applicable state Laws as the case may be, as Triangle may request; provided, that, no opinion of counsel shall be required if the Purchaser is effecting a sale of the Shares pursuant to Rule 144 under the Securities Act (and the Purchaser delivers a Rule 144 Representation Letter to Triangle), or the Shares have been registered under the Securities Act pursuant to an effective registration statement.  Triangle shall reasonably cooperate with the Purchaser to effect removal of such legend.  The legend on the Shares shall be removed and Triangle shall issue new shares of Common Stock without such legend to the holder of the Shares upon which it is stamped, if, unless otherwise required by state securities Laws, (i) such Shares are sold pursuant to an effective registration statement, (ii) in connection with a sale, assignment or other transfer, such holder provides Triangle with an opinion of a law firm reasonably acceptable to Triangle, in a generally acceptable form, to the effect that such sale, assignment or transfer of such Shares may be made without registration under the applicable requirements of the Securities Act, or (iii) in connection with a sale, assignment of or other transfer of such Shares, such holder provides Triangle with a representation letter that such Shares will be sold, assigned or transferred pursuant to Rule 144 under the Securities Act (a “Rule 144A Representation Letter”).  Triangle shall bear all direct costs and expenses associated with the removal of a legend pursuant to this Section 7.09; provided, that the Purchaser shall be responsible for all legal fees and expenses of counsel incurred by the Purchaser with respect to matters addressed in this Section 7.09.

(b)                                 Certificates evidencing Shares shall not contain any legend (including the legend set forth in Section 4.05(d)(i)), (i) while a registration statement covering the resale of such security is effective under the Securities Act and the Purchaser delivers to Triangle a representation letter agreeing that such Shares will be sold under such effective registration statement, or (ii) following any sale of such Shares pursuant to Rule 144, (iii) if such Shares may be sold free of restrictions pursuant to Rule 144(b) or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).

Section 7.10                             Entire Agreement.  This Agreement, the other Transaction Documents and the other agreements and documents referred to herein are intended by the Parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the Parties in respect of the subject matter contained herein and therein.  There are no restrictions, promises, warranties or undertakings between the Parties, other than those set forth or referred to herein or the other Transaction Documents with respect to the rights granted by Triangle or any of its Affiliates or the Purchaser or any of their Affiliates set forth herein or therein.  This Agreement, the other Transaction Documents and the other agreements and documents referred to herein or therein supersede all prior agreements and understandings between the Parties with respect to such subject matter.

Section 7.12                             Waiver of Jury Trial.  THE PARTIES TO THIS AGREEMENT EACH HEREBY WAIVES, AND AGREES TO CAUSE ITS AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE.  THE PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.
