Section 3.11 Books and Records; Xxxxxxxx-Xxxxx 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.

(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 Xxxxxxxx-Xxxxx Act of 2002 and the rules and regulations promulgated in connection therewith.

Section 3.12 No Material Adverse Change.

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

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) Xxxxxx, Xxxxxxxxx & 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.

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.

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

In addition, Triangle agrees that it will indemnify and hold harmless the Purchaser from and against any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees or commissions incurred by Triangle or alleged to have been incurred by Triangle in connection with the sale of the Shares or the consummation of the transactions contemplated by the Transaction Documents.

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

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

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.

Triangle shall reasonably cooperate with the Purchaser to effect removal of such legend.

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).

Notwithstanding anything to the contrary herein, in no event shall Triangle be required to effectuate a Demand Registration for Registrable Securities having an aggregate value of less than $30 million based on the VWAP of such Registrable Securities as of the date of the Demand Notice.

(ii) Within five Business Days of the receipt of the Demand Notice, Triangle shall give written notice of such Demand Notice to all Holders and, as soon as reasonably practicable thereafter, shall, subject to the limitations of this Section 2(a), file a Registration Statement covering all of the Registrable Securities that the Holders shall in writing request (such request to be given to Triangle within three days of receipt of such notice of the Demand Notice given by Triangle pursuant to this Section 2(a)(ii)) to be included in such Demand Registration as promptly as practicable as directed by the Initiating Holder in accordance with the terms and conditions of the Demand Notice and use all commercially reasonable efforts to cause such Registration Statement to become effective under the Securities Act and remain effective under the Securities Act until all Registrable Securities covered by such Registration Statement have been sold (the “Effectiveness Period”).

(iii) Subject to the other limitations contained in this Agreement, Triangle is not obligated hereunder to effect (A) more than one Demand Registration in any 12 month period, (B) more than a total of three Demand Registrations pursuant to this Agreement and (C) a subsequent Demand Registration pursuant to a Demand Notice if a Registration Statement covering all of the Registrable Securities held by the Holders providing such Demand Notice shall have become effective under the Securities Act and remains effective under the Securities Act and is sufficient to permit offers and sales of the number and type of Registrable Securities on the terms and conditions specified in the Demand Notice in accordance with the intended timing and method or methods of distribution thereof specified in the Demand Notice.

(iv) Notwithstanding any other provision of this Section 2(a), Triangle shall not be required to effect a registration or file a Registration Statement (or any amendment thereto) for a period of up to 60 days, if (A) the Board determines that a postponement is in the best interest of Triangle and its stockholders generally due to a pending transaction involving Triangle, (B) the Board determines such registration would render Triangle unable to comply with applicable securities laws or (C) the Board determines such registration would require disclosure of material information that

Triangle has a bona fide business purpose for preserving as confidential (any such period, a “Blackout Period”); provided, however, that (i) in no event shall any Blackout Period together with any Suspension Period collectively exceed an aggregate of 120 days in any 12 month period, (ii) during any Blackout Period contemplated by Section 2(a)(iv)(B) or any Suspension Period, Triangle shall not engage in any transaction involving the offer, issuance, sale, or purchase of Triangle Securities (whether for the benefit of Triangle or a third Person), except transactions involving the issuance or purchase of Triangle Securities as contemplated by Triangle employee benefit plans or employee or director arrangements or in connection with the conversion or exercise of outstanding securities, including the Convertible Note, and (iii) during any Blackout Period contemplated by Section 2(a)(iv)(B) or (C) or any Suspension Period, Triangle shall not file a registration statement (or any amendment or supplement thereto) for any other holder of registration rights.

(v) Triangle may include in any such Demand Registration other Triangle Securities for sale for its own account or for the account of any other Person; provided that if the managing underwriter, if any, for the Underwritten Offering determines that the type or number of Triangle Securities proposed to be offered in such offering would likely have an adverse effect in any material respect on the price, timing or distribution of the Registrable Securities proposed to be included in such offering, the Registrable Securities to be sold by the Holders shall be included in such registration before any Triangle Securities proposed to be sold for the account of Triangle or any other Person other than the NGP Holders.

(vi) Subject to the limitations contained in this Agreement, Triangle shall effect any Demand Registration on Form S-3 (except if Triangle is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such Demand Registration shall be effected on another appropriate form for such purpose pursuant to the Securities Act) and if Triangle becomes, and is at the time of its receipt of a Demand Notice, a WKSI, the Demand Registration for any offering and selling of Registrable Securities shall be effected pursuant to an Automatic Shelf Registration Statement, which shall be on Form S-3 or any equivalent or successor form under the Securities Act (if available to Triangle); provided, however, that if at any time a Registration Statement on Form S-3 is effective and a Holder provides written notice to Triangle that it intends to effect an offering of all or part of the Registrable Securities included on such Registration Statement, Triangle will amend or supplement such Registration Statement as may be necessary in order to enable such offering to take place.

(vii) Without limiting Section 3, in connection with any Demand Registration pursuant to and in accordance with this Section 2(a), Triangle shall, (A) promptly prepare and file or cause to be prepared and filed (1) such additional forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents, as may be necessary or advisable to register or qualify the securities subject to such Demand Registration, including under the securities laws of such states as the Holders shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, Triangle would become subject to general service of process or to taxation or qualification to do business in such

jurisdiction solely as a result of registration and (2) such forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to such Demand Registration on the Trading Market and (B) do any and all other acts and things that may be reasonably necessary or appropriate or reasonably requested by the Holders to enable the Holders to consummate a public sale of such Registrable Securities in accordance with the intended timing and method or methods of distribution thereof.

(ix) In the event a Holder transfers Registrable Securities included on a Registration Statement and such Registrable Securities remain Registrable Securities following such transfer, at the request of such Holder, Triangle shall amend or supplement such Registration Statement as may be necessary in order to enable such transferee to offer and sell such Registrable Securities pursuant to such Registration Statement; provided that in no event shall Triangle be required to file a post-effective amendment to the Registration Statement unless (A) such Registration Statement includes only Registrable Securities held by the Holder, Affiliates of the Holder or transferees of the Holder or (B) Triangle has received written consent therefor from whom Registrable Securities have been registered on (but not yet sold under) such Registration Statement, other than the Holder, Affiliates of the Holder or transferees of the Holder.

(x) The rights of the Holders under this Section 2(a) shall terminate at such time that both (A) the number of Registrable Securities is less than 3% of the number of outstanding shares of Common Stock, and (B) such Registrable Securities may be sold or transferred by the Holder thereof under Rule 144 under the Securities Act without any limitation on the volume or timing.

(b) Piggyback Registration.

(i) If Triangle shall at any time propose to conduct, other than pursuant to any Demand Registration, a public offering of Common Stock for cash (whether in connection with a public offering of Common Stock by Triangle, a public offering of Common Stock by stockholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or S-8 or an offering on any registration statement form that does not permit secondary sales), Triangle shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five Business Days before) the commencement of the offering (the “Piggyback Notice”). The Piggyback Notice shall offer the Holders the opportunity to include for registration in such Registration Statement the number of Registrable Securities as they may request (a “Piggyback Registration”). Triangle shall use commercially reasonable efforts to include in each such Piggyback Registration such Registrable Securities for which Triangle has received a written request from a Holder within three Business Days after delivery of the Piggyback Notice to such Holder (“Piggyback Request”) for inclusion therein. If a Holder decides not to include all of its Registrable Securities in any Registration Statement thereafter filed by Triangle, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by

Triangle with respect to offerings of Common Stock, all upon the terms and conditions set forth herein.

(ii) If the Registration Statement under which Triangle gives notice under this Section 2(b) is for an underwritten offering, Triangle shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Section 2(b) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by Triangle. If the managing underwriter or managing underwriters of such offering advise Triangle and the Holders in writing that in their reasonable opinion that the inclusion of all of the Holders’ Registrable Securities in the subject Registration Statement (or any other Common Stock proposed to be included in such offering) would likely have an adverse effect in any material respect on the price, timing or distribution of Common Stock proposed to be included in such offering, Triangle shall include in such offering only that number of shares of Common Stock proposed to be included in such offering that, in the reasonable opinion of the managing underwriter or managing underwriters, will not have such effect, with such number to be allocated as follows:

(A) if such registration statement is filed other than pursuant to a demand registration initiated by the NGP Holders, (i) first, to Triangle, (ii) if there remains availability for additional shares of Common Stock to be included in such registration, second pro rata among the NGP Holders and all Holders desiring to register Registrable Securities based on the number of Registrable Securities held by all such Holders and the number of registrable securities held by the NGP Holders, and (iii) if there remains availability for additional shares of Common Stock to be included in such registration, third pro-rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration.

(B) if such registration statement is filed pursuant to a demand registration initiated by the NGP Holders, (i) first, to the NGP Holders, (ii) if there remains availability for additional shares of Common Stock to be included in such registration, second pro rata to the Holders desiring to register Registrable Securities based on the number of Registrable Securities held by all such Holders, and (iii) if there remains availability for additional shares of Common Stock to be included in such registration, third pro-rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration.

If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to Triangle and the managing underwriter(s) delivered on or prior to the time of the commencement of such offering. Any Registrable

Securities withdrawn from such underwriting shall be excluded and withdrawn from the registration.

(iii) Triangle shall have the right to terminate or withdraw any registration initiated by it under this Section 2(b) at any time in its sole discretion whether or not any Holder has elected to include Registrable Securities in such Registration Statement. The registration expenses of such withdrawn registration shall be borne by Triangle in accordance with Section 4 hereof.

(iv) The rights of the Holders under this Section 2(b) shall terminate if the number of Registrable Securities is less than 5% of the number of outstanding shares of Common Stock.

In connection therewith, if required by Triangle’s transfer agent, Triangle will promptly, after the Effective Date of the Registration Statement, cause an opinion of counsel as to the effectiveness of the Registration Statement to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to issue such Registrable Securities without any such legend upon sale by the Holder of such Registrable Securities under the Registration Statement.

(k) Such Holders may distribute the Registrable Securities by means of an underwritten offering; provided that (i) in the case of a Demand Registration, (A) the Initiating Holder provides written notice to Triangle of its intention to distribute Registrable Securities by means of an underwritten offering, which for the avoidance of doubt may be made at a date later than the original Demand Notice (the “Underwritten Offering Notice” and such underwritten offering being referred to herein as an “Underwritten Offering”) and (B) Holders (including the Initiating Holder) having an aggregate value of at least $30 million based on the VWAP of such Registrable Securities as of the date of such Underwritten Offering Notice desire to participate in such Underwritten Offering and, in the case of a Piggyback Registration, the electing Holders must include their Registrable Securities in an underwritten offering if the Piggyback Notice so requires, (ii) the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein, (iii) the managing underwriter or managing underwriters thereof shall be designated by the Initiating Holder in the case of a Demand Registration (provided, however, that such designated managing underwriter or managing underwriters shall be reasonably acceptable to Triangle), by Triangle in the case of a registration initiated by Triangle or by such other holder in the case of a registration initiated by another holder, (iv) each Holder participating in such underwritten offering agrees to enter into an underwriting agreement in customary form and sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled to select the managing underwriter or managing underwriters hereunder and (v) each Holder participating in such underwritten offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. Triangle hereby agrees with each Holder that, in connection with any Underwritten Offering in accordance with the terms hereof, it will negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, including using all commercially reasonable efforts to procure customary legal opinions and auditor “comfort” letters. Notwithstanding the foregoing, Triangle is not obligated to effect more than (A) one Underwritten Offering in any 12 month period and (B) a total of three Underwritten Offering pursuant to this Agreement. If, in the case of an Underwritten Offering, the managing underwriter advises Triangle that the inclusion of all of the Holders’ Registrable Securities in the subject Underwritten Offering would likely have an adverse effect in any material respect on the price, timing or distribution of Registrable Securities proposed to be included in such Underwritten Offering, then Triangle shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Common Stock that may be included in the Underwritten Offering shall be allocated:

(A) in the case of a demand registration initiated by the NGP Holders, (i) first to the NGP Holders and (ii) second to the Holders on a pro rata basis based on the number of Registrable Securities held by all such Holders.

(B) in the case of a Demand Registration, (i) first to the Holders on a pro rata basis based on the number of Registrable Securities held by all such Holders (including the Initiating Holders) and (ii) second to the NGP Holders.

Any Registrable Securities excluded or withdrawn from such Underwritten Offering shall be withdrawn from the Underwritten Offering. In the event that the managing underwriter limits the number of Registrable Securities to be included in the Underwritten Offering pursuant to this Section 3(k) such that at least one-third of the aggregate Registrable Securities set forth in such Holders’ written requests pursuant to this Section 3(k) are included in the Underwritten Offering, such Underwritten Offering shall not be considered to be an Underwritten Offering for purposes of the limitations set forth in this Section 3(k).

(l) In the event such Holders seek to complete an Underwritten Offering, for a reasonable period prior to the filing of any Registration Statement and throughout the Effectiveness Period, Triangle will make available upon reasonable notice at Triangle’s principal place of business or such other reasonable place for inspection during normal business hours by the managing underwriter or managing underwriters selected in accordance with Section 3(k) such financial and other information and books and records of Triangle, and cause the officers, employees, counsel and independent certified public accountants of Triangle to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in such counsel’s reasonable belief) to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act.

(m) In connection with any Demand Registration, Triangle will use commercially reasonable efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in presentations, meetings and road shows.

(n) Triangle may require the Holder to furnish to Triangle any other information regarding the Holder and the distribution of such securities as Triangle reasonably determines is required to be included in any Registration Statement.

4. Registration Expenses. All Registration Expenses incident to the Parties’ performance of or compliance with their respective obligations under this Agreement or otherwise in connection with any Demand Registration or Piggyback Registration (in each case, excluding any Selling Expenses) shall be borne by Triangle, whether or not any Registrable Securities are sold pursuant to a Registration Statement. “Registration Expenses” shall include, without limitation, (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with the Trading Market and (B) in compliance with applicable state securities or “Blue Sky” laws), (ii) printing expenses (including expenses of printing certificates for Triangle Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by a Holder of Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel, auditors and accountants for Triangle, (v) Securities Act liability insurance, if Triangle so desires such insurance, (vi) fees and expenses of all other Persons retained by Triangle in connection with the consummation of the transactions contemplated by this Agreement and (vii) all expenses relating to marketing the sale of the Registrable Securities, including expenses related to conducting a “road show.” In addition, Triangle shall be responsible for all of its expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including expenses payable to third parties and including all salaries and expenses of their officers and employees performing legal or

accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on the Trading Market.

5. Indemnification.

(a) Triangle shall indemnify and hold harmless each Holder, its Affiliates and each of their respective officers and directors and any Person who controls any such Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Holder Indemnified Persons”), to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses, judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which any Registrable Securities were registered, in any preliminary prospectus (if Triangle authorized the use of such preliminary prospectus prior to the Effective Date), or in any summary or final prospectus or free writing prospectus (if such free writing prospectus was authorized for use by Triangle) or in any amendment or supplement thereto (if used during the period Triangle is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which they were made, not misleading; provided, however, that Triangle shall not be liable to any Holder Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary or final prospectus or free writing prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to Triangle by or on behalf of such Holder Indemnified Person or any underwriter specifically for use in the preparation thereof. Triangle shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which Triangle is aware in connection with the transactions contemplated by this Agreement. Notwithstanding anything to the contrary herein, this Section 5 shall survive any termination or expiration of this Agreement indefinitely.

(b) In connection with any Registration Statement in which a Holder participates, such Holder shall indemnify and hold harmless Triangle, its Affiliates and each of their respective officers, directors and any Person who controls Triangle (within the meaning of the Securities Act) and any agent thereof (collectively, the “Triangle Indemnified Persons”), to the fullest extent permitted by applicable law, from and against any and all Losses as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any such Registration Statement, in any preliminary prospectus (if used prior to the Effective Date of such Registration Statement), or in any summary or final prospectus or free writing prospectus or in any amendment or supplement thereto (if used during the period Triangle is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which they

were made, not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to the Holder furnished in writing to Triangle by such Holder for use therein.

(c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim or there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim. Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

6. Facilitation of Sales Pursuant to Rule 144. To the extent it shall be required to do so under the Exchange Act, Triangle shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144. Upon the request of any Holder in connection with that Holder’s sale pursuant to Rule 144, Triangle shall deliver to such Holder a written statement as to whether it has complied with such requirements.

7. [Intentionally Omitted]

8. Preemptive Rights.

(a) Except in the case of Excluded Securities, Triangle shall not issue, exchange or otherwise Dispose, agree to issue, exchange or otherwise Dispose, or reserve or set aside for the same, any Equity Securities of Triangle or any securities convertible into or exchangeable for Equity Securities of Triangle (the “Offered Securities”), unless in each case Triangle shall have first given written notice to Purchaser (the “Preemptive Offer Notice”) at least 10 Business Days prior to entering into a definitive agreement for such sale stating that Triangle proposes to sell such Offered Securities, the number or amount of the Offered Securities proposed to be sold, the proposed purchase price or price range therefor and any other terms and conditions of such offer.

(b) On or before the seventh Business Day following the date of the Preemptive Offer Notice (the “Preemptive Offer Period”), the Purchaser shall have the option to subscribe for up to its pro rata share of such Offered Securities (based on its percentage ownership of Common Stock calculated on a fully-diluted basis using the treasury stock method and assuming full conversion of any outstanding convertible notes of the Company) by delivering written notice to Triangle (a “Preemptive Offer Acceptance Notice”). Notwithstanding the preceding sentence, the number of Offered Securities that the Purchaser is entitled to purchase shall not exceed an amount that would require Stockholder Approval under, or would result in a violation of, the rules and regulations of NYSE MKT or any other principal stock exchange or market upon which the Offered Securities trade; provided, however, that if the Purchaser cannot purchase at least 75% of the number of Offered Securities as to which a Preemptive Offer Acceptance Notice has been given by the Purchaser as a result of the limitations set forth in this sentence, then Triangle shall not issue, exchange or otherwise Dispose, agree to issue, exchange or otherwise Dispose, or reserve or set aside for the same all or any part of the Offered Securities without the prior written consent of the Purchaser. Each Preemptive Offer Acceptance Notice shall specify: (i) the amount of Offered Securities the Purchaser desires to subscribe for and (ii) the prices at which the Purchaser is willing to purchase such amounts of the Offered Securities at each such price.

(c) Triangle shall have 30 days from the expiration of the Preemptive Offer Period to enter into a definitive agreement to issue and sell all or any part of such Offered Securities as to which a Preemptive Offer Acceptance Notice has not been given by the Purchaser (the “Refused Securities”) to any other Persons, but only upon terms and conditions in all material respects, including price, which are no more favorable, individually or in the aggregate, to such other Persons or less favorable, individually or in the aggregate, to Triangle than those set forth in the Preemptive Offer Notice. Upon the closing, which shall occur at a reasonable time and place within 60 days from the expiration of the Preemptive Offer Period (which such period shall be extended for up to 180 days with respect to any Person seeking to purchase Offered Securities, including the Purchaser, for such time as is necessary to allow such Person to request any approvals required under the HSR Act) and shall include full payment to Triangle of the proceeds from the sale to such other Persons of all the Refused Securities, the Purchaser shall purchase from Triangle, and Triangle shall sell to the Purchaser, the Offered Securities with respect to which a Preemptive Offer Acceptance Notice was delivered by the Purchaser, at the terms specified in the Preemptive Offer Notice. In each case, any Offered Securities not purchased by the Purchaser or any other Persons in accordance with this Section 8(c) within 60 days (or such longer period if the time period within which to close is extended as provided in the immediately preceding sentence) after the expiration of the Preemptive Offer Period may not be sold or otherwise Disposed of until they are again offered to the Purchaser under the procedures specified in this Section 8(c).

(d) The rights of the Purchaser under this Section 8 shall terminate upon the occurrence of a Termination Event and shall not apply to the following securities (the “Excluded Securities”):

(i) the issuance of any Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle pursuant to any employee benefits or other compensation plan approved by the Board and the Stockholders;

(ii) Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle issued otherwise than for cash pursuant to, a merger, consolidation, acquisition, disposition or similar business combination approved by the Board;

(iii) Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle issued upon any stock dividend, stock split or other pro-rata distribution, subdivision or combination of securities or other recapitalization of Triangle;

(iv) Equity Securities issued upon conversion of the Convertible Note and other convertible notes issued concurrently herewith; and

(v) Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle issued pursuant to the terms of a “poison pill” or other stockholder rights plan.

9. Director Designation Rights.

(a) Board Representation.

(i) On the date on which the aggregate consideration paid by Purchaser and its Affiliates to Triangle for shares of Common Stock from Triangle exceeds $150 million, the Board shall adopt resolutions that (i) increase the number of natural persons that constitute the whole Board by one (1) person and (ii) fill the vacancy created by virtue of such increase in the size of the Board with an individual designated by the Purchaser, in each case pursuant to the Triangle Organizational Documents, who must in the reasonable judgment of Triangle, (A) qualify as an Independent Director, (B) have the requisite skill and experience to serve as a director of a publicly traded company, (C) not be prohibited or disqualified from serving as a director of Triangle pursuant to the Triangle Bylaws (as in effect as of the date hereof) or any rule or regulation of the Commission, NYSE MKT (or any other principal stock exchange or market upon which the Common Stock may trade) or by applicable law and (D) otherwise be reasonably acceptable to Triangle (the “Designated Director”). The Purchaser shall, and shall cause the Designated Director to, timely provide Triangle with accurate and complete information relating to the Purchaser and the Designated Director that may be required to be disclosed by Triangle under the Exchange Act. In addition, at Triangle’s request, the Purchaser shall cause the Designated Director to complete and execute Triangle’s standard director and officer questionnaire and provide such other information as Triangle may reasonably request prior to being admitted to the Board or standing for reelection at an annual meeting of Stockholders or at such other time as may be requested by Triangle.

(ii) The Designated Director will hold office until his or her term expires and such Designated Director’s successor has been duly elected and qualified or until such Designated Director’s earlier death, resignation or removal.

(iii) In order to designate an individual for appointment to the Board, the Purchaser must submit to Triangle a written notice in accordance with the notice provisions set forth in Section 7.08 of the Purchase Agreement, which notice shall include (i) the name, age, business address and residence address of such designee, (ii) a current resume and curriculum vitae of such designee and (iii) a statement describing such designee’s qualifications.

(iv) Prior to a Termination Event:

(A) in connection with each annual meeting of Stockholders, and subject to the conditions of Section 9(a)(i) of this Agreement, Triangle shall nominate the Designated Director for reelection to the Board and shall take all reasonable and lawful actions necessary or advisable to cause the Board to recommend that the Stockholders vote “FOR” the election of the Designated Director;

(B) promptly following any annual meeting of Stockholders at which the Designated Director is not elected to the Board, and subject to the provisions of Section 9(a)(i) of this Agreement, the Board shall adopt resolutions that (1) increase the number of natural persons that constitute the whole Board by one (1) person and (2) fill the vacancy created by virtue of such increase in the size of the Board with the Designated Director; and if the Board is prevented by Section 3.1 of the Triangle Bylaws from complying with clause (1) of this Section 9(a)(iv)(B), the Board shall amend the Triangle Bylaws as necessary to permit the Board to comply with clause (1) of this Section 9(a)(iv)(B);

(C) any Designated Director may be removed pursuant to Section 3.6 of the Triangle Bylaws, and any vacancy created by such removal shall be filled by the Board with an individual designated by the Purchaser who, subject to the conditions of Section 9(a)(i) of this Agreement, shall become the Designated Director;

(D) upon written notice from Triangle to the Purchaser that a Resignation Event has occurred, which notice shall set forth in reasonable detail the facts and circumstances constituting the Resignation Event, the Purchaser will cause the Designated Director then serving as a member of the Board to resign as a member of the Board within two (2) Business Days of such written notice; and

(E) any vacancy caused by the death, disability or resignation of the Designated Director shall be filled by the Board with an individual designated by the Purchaser who, subject to the conditions of Section 9(a)(i) of this Agreement, shall become the Designated Director.

(v) Any action by the Purchaser to designate or replace the Designated Director shall be evidenced in writing furnished to Triangle and shall be signed by or on behalf of the Purchaser.

(vi) Prior to designating a Designated Director, the Purchaser shall enter into a written agreement in a form reasonably satisfactory to Triangle with the Designated Director whereby such Designated Director agrees to resign as a member of the Board upon a Resignation Event, a Termination Event or at the Purchaser’s request, as applicable. The Purchaser acknowledges and agrees that such an agreement is in the best interest of Triangle and the Purchaser, and that Triangle shall be a third party beneficiary of the terms and conditions of such an agreement, and Triangle shall have the right to enforce such an agreement to the same extent as the parties thereto.

(vii) Triangle shall not take any action that would lessen, restrict, prevent or otherwise have an adverse effect upon the foregoing rights of the Purchaser to Board representation, including by nominating more directors for election to the Board than the number of directors constituting the full Board; provided, however, that Triangle shall not be prohibited from taking such action that the Board determines (i) may be necessary to (A) comply with any rule or regulation of the Commission or NYSE MKT (or any other principal stock exchange or market upon which the Common Stock may trade) or (B) comply with applicable law or (ii) is required to comply with the provisions of the Triangle Organizational Documents.

(b) Termination of Director Designation Rights. Upon the occurrence of a Termination Event, the Purchaser’s right to designate, and Triangle’s obligation to nominate, the Designated Director shall automatically terminate, and the Purchaser shall cause the Designated Director then serving as a member of the Board, promptly upon (and in any event within two (2) Business Days following) receipt of a written request from Triangle, to resign as a member of the Board. In the event Triangle does not request that the Designated Director be caused to resign upon occurrence of a Termination Event, such Designated Director will no longer be considered a designee of the Purchaser and will be subject to election and reelection in accordance with the Triangle Bylaws. The Purchaser shall have the right at any time to cause the Designated Director to resign as a member of the Board and to waive its rights to designate a nominee for election to the Board.

(c) Director Indemnification. At all times while the Designated Director is serving as a member of the Board, and following any such Designated Director’s death, resignation, removal or other cessation as a director in such former Designated Director’s capacity as a former director, each Designated Director shall be entitled to all rights to indemnification and exculpation as are then made available to any other member of the Board. As between Triangle, on the one hand, and the Purchaser and its Affiliates, on the other hand, Triangle shall, in all events, be the full indemnitor of first resort and shall not be entitled to any contribution, indemnification or other payment by or from any of the Purchaser or its Affiliates.

(d) Corporate Opportunities. Triangle hereby renounces any interest or expectancy in any business opportunity in which Teachers Insurance and Annuity Association of America, a New York stock life insurance company, or Purchaser or any of their respective Affiliates or Portfolio Companies (including any officers or directors thereof) (the “TIAA Group”) participates or seeks to participate (each, a “Business Opportunity”) other than a Business Opportunity that is presented to a Designated Director in such Person’s capacity as a director of Triangle and with respect to which no other member of the TIAA Group (other than

the Designated Director) independently receives notice or otherwise identifies such Business Opportunity (each Business Opportunity that is so renounced, being referred to as a “Renounced Business Opportunity”). No member of the TIAA Group, including any Designated Director, shall have any obligation to communicate or offer any Renounced Business Opportunity to Triangle, and any member of the TIAA Group may pursue a Renounced Business Opportunity. Notwithstanding anything to the contrary in this Section 9(d), Triangle shall not be prohibited from pursuing any Business Opportunity with respect to which it has renounced any interest or expectancy as a result of this Section 9(d).

10. Approval Right. So long as (a) 50% or more of the Common Stock purchased by the Purchaser pursuant to the Purchase Agreement is issued and outstanding and held by the Purchaser and (b) Purchaser owns at least 10% of the then issued and outstanding Common Stock, Triangle shall not, and shall cause its Subsidiaries not to, directly or indirectly, Incur any Indebtedness (other than pursuant to the Triangle Credit Agreement or the terms of the Notes); provided, however, that Triangle may Incur Indebtedness and any of its Subsidiaries may Incur Indebtedness if on the date thereof the Consolidated Leverage Ratio does not exceed 5.0 to 1.0 (provided that the Triangle Credit Agreement and Notes are excluded from such calculation).

11. Miscellaneous.

(a) Remedies. In the event of a breach by Triangle of any of its obligations under this Agreement, each Holder, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. Triangle agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b) Discontinued Disposition. Each Holder agrees that, upon receipt of a notice from Triangle of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(e) (a “Suspension Notice”), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement as contemplated by Section 3(j) or until it is advised in writing by Triangle that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “Suspension Period”). Triangle may provide appropriate stop orders to enforce the provisions of this Section 11(b).

(c) Amendments and Waivers. No provision of this Agreement may be waived or amended except in a written instrument signed by Triangle and Holders that hold a majority of the Registrable Securities as of the date of such waiver or amendment. Triangle shall provide prior notice to all Holders of any proposed waiver or amendment. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver

of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right.

(d) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Section 11(d) prior to 5:00 p.m. (Denver Time) on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Agreement later than 5:00 p.m. (Denver Time) on any date and earlier than 11:59 p.m. (Denver Time) on such date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service or (iv) upon actual receipt by the Party to whom such notice is required to be given.

Except as provided in this Section 11(e), this Agreement, and any rights or obligations hereunder, may not be assigned without the prior written consent of Triangle and the Purchaser. Notwithstanding anything in the foregoing to the contrary, (i) the registration rights of a Holder pursuant to this Agreement with respect to all or any portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided (A) Triangle is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned and (B) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in this Agreement, and (ii) the rights of the Purchaser under Section 8 may be transferred or assigned in whole or in part by the Purchaser to an Affiliate of the Purchaser provided that (1) Triangle is, within a reasonable time after such transfer, furnished with written notice of the name and address of such Affiliate and (B) such Affiliate agrees in writing to be bound by and subject to the terms set forth in this Agreement. Triangle may not assign its respective rights or obligations hereunder without the prior written consent of the Purchaser.

(f) Third Party Beneficiaries. Other than the Holders (other than the Purchaser), there are no third party beneficiaries having rights under or with respect to this Agreement.

(g) Execution and Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile or electronic mail transmission, such signature shall create a valid binding obligation of the Party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such signature delivered by facsimile or electronic mail transmission were the original thereof.

(h) Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York, without reference to the choice of law provisions thereof.

relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each Party anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the Parties irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.
