or by general equity principles (regardless of whether such enforceability is considered in a proceeding in equity or at law). Upon their respective execution by the Company and the other parties thereto and assuming that they constitute legal and
binding agreements of the other parties thereto, each of the Transaction Agreements will constitute a

pre-emptive or similar rights and will rank pari passu in all respects with all other existing shares of Common Stock. The Firm Shares have been duly authorized and, upon issuance in accordance with the terms
hereof, will be validly issued, fully paid and non-assessable and will not be subject to any pre-emptive or similar rights and will rank pari passu in all respects with

business or described in the SEC Reports or pursuant to that certain Development Agreement dated as of October 14, 2016.

patent, trademark, service mark, trade name, copyright, trade secret, license in or other intellectual property right or franchise right of any person. The Company has taken all reasonable steps to protect, maintain and safeguard its rights in all
Intellectual Property, including the execution of appropriate nondisclosure and confidentiality agreements. The consummation of the transactions contemplated by this Agreement will not result in the loss or impairment of or payment of any additional
amounts with respect to, nor require the consent of any other person in respect of, the right of the Company to own, use or hold for use any of the Intellectual Property as owned, used or held for use in the conduct of the businesses as currently

agreement or instrument, credit facility, franchise, license, judgment, order, statute, law, ordinance, rule or regulations, applicable to the Purchasers or their respective properties or assets, except, in the case of clause (ii), as would not,
individually or in the aggregate, be reasonably expected to materially delay or hinder the ability of the Purchasers to perform their obligations under the Transaction Agreements (a “Purchaser Adverse Effect”). 

4.4.    Consents. All consents, approvals, orders and authorizations required on the part of the Purchasers in
connection with the execution, delivery or performance by the Purchasers of the Transaction Agreements to which it is a party have been obtained or made, other than (i) the expiration or termination of the applicable waiting period under the

Effect. 
 4.5.    Absence of Litigation. As of the date hereof, there is no action, suit, proceeding,
investigation or inquiry pending or, to the Purchasers’ knowledge, threatened by or before any Governmental Authority against the Purchasers which, individually or in the aggregate, would reasonably be expected to have a Purchaser Adverse

 - 20 - 

 4.9.    Investor Status. 

(a)    The Purchasers certify and represent to the Company that the Purchasers are each an “accredited investor”
as defined in Rule 501 of Regulation D promulgated under the Securities Act. 
 (b)    The Purchasers (i) have
such knowledge and experience in financial and business matters as to be able to evaluate the risks and merits of its prospective investment in the Securities and (ii) have the ability to bear the economic risks of its prospective investment

 4.10.    Offer and Sale of Securities Not
Registered. The Purchasers understand that the offer and sale of the Securities have not been registered under the Securities Act, by reason of their issuance by the Company in a transaction exempt from the registration requirements of the
Securities Act, and that the Securities must continue to be held by the Purchasers unless a subsequent disposition thereof is registered under the Securities Act or is exempt from such registration and in each case in accordance with any applicable
securities laws of any state of the United States. The Purchasers understand that the exemptions from registration afforded by Rule 144 (the provisions of which are known to it) promulgated under the Securities Act depend on the satisfaction of
various conditions including, but not limited to, as to manner of sale and a minimum holding period, and on requirements relating to the Company which are outside of the Purchasers’ control and which the Company is under no obligation and may
not be able to satisfy, and that, if applicable, Rule 144 may afford the basis for sales only in limited amounts. The Purchasers understand that the purchase of the Securities and other rights afforded to the Purchasers or their Affiliates pursuant
to the Transaction Documents may deem the Purchasers and their Affiliated Entities “affiliates” of the Company within the meaning of Rule 144 and as a result further restrict the Purchasers’ ability to resell or transfer the
Securities under Rule 144. 
 4.11.    Legends. The Purchasers understand that the certificates evidencing the
Firm Shares or the book-entry accounts maintained by the transfer agent evidencing ownership of the Firm Shares, as applicable, will bear the following legend or restrictive notation: 

“THE OFFER AND SALE OF THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THESE SECURITIES MAY NOT
BE SOLD, OFFERED FOR SALE, PLEDGED OR 

  
 - 21 - 

 
HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER AND, IN THE CASE OF A
TRANSACTION EXEMPT FROM REGISTRATION, UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT OR THE ISSUER HAS RECEIVED DOCUMENTATION REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER SUCH ACT.” 

4.12.    Reliance by the Company. The Purchasers acknowledge that the Company will rely upon the truth and accuracy
of, and the Purchasers’ compliance with, the representations, warranties, agreements, acknowledgements and understandings of the Purchasers set forth herein. 

5.    Covenants. 

5.1.    HSR Approval. The Company and the Purchasers acknowledge that one or more filings under the HSR Act may be
necessary in connection with the issuance of the Conversion Shares upon conversion of the Notes. The Purchasers shall be solely responsible for determining whether any filings under the HSR Act or any foreign antitrust requirements may be necessary
in connection with any conversion of Notes held by them and will promptly notify the Company if any such filing is required. If the Purchasers determine that any such filing is required, the Purchasers shall not convert the Notes until such time as
the applicable requirements of the HSR Act or such foreign antitrust requirements have been satisfied and any related approvals, consents or waivers have been received, or such time as the Purchasers determine that such requirements are no longer
applicable. To the extent reasonably requested, the Company will cooperate with the Purchasers in timely making or causing to be made all applications and filings under the HSR Act or any non-U.S. antitrust
requirements in connection with the issuance of the Conversion Shares upon conversion of Notes held by the Purchasers as promptly as reasonably practicable or as required by the law of the applicable jurisdiction. The Company shall as promptly as
reasonably practicable provide from time-to-time such information and documentation regarding the Company as the Purchasers or their assignees may reasonably request in
order to determine what non-U.S. antitrust requirements may exist with respect to any potential conversion of the Notes. The Purchasers shall be responsible for the payment of the filing fees associated with
any such applications or filings. For the avoidance of doubt, any delivery of the Conversion Shares upon conversion of the Notes shall be subject to the terms and conditions of the Indenture. 

5.2.    Shares Issuable Upon Conversion. At any time that the Notes are outstanding, the Company shall cause to be
maintained all authorizations required for the issuance of a number of Conversion Shares which the Company may be liable to issue upon the conversion of the Notes from time to time remaining outstanding, in accordance with the terms and conditions
of the Notes. All Conversion Shares delivered upon conversion of the Notes shall be newly issued shares or shares held in treasury by the Company, shall have been duly authorized and validly issued and shall be fully paid and non-assessable and free of any lien and shall not be subject to any pre-emptive rights or similar rights and shall rank pari passu in all respects with other existing shares
of Common Stock. The Company will cause any Conversion Shares issued upon conversion of the Notes to be listed with the NYSE MKT or, if the Common Stock is no longer listed on the NYSE MKT, the primary stock exchange or quotation system on which the
Common Stock is then listed or quoted.

 5.3.    Further Assurances. Each party agrees to cooperate with each
other and their respective officers, employees, attorneys, accountants and other agents, and, generally, do such other reasonable acts and things in good faith as may be necessary to effectuate the intents and purposes of this Agreement, subject to
the terms and conditions hereof and compliance with applicable law, including taking reasonable action to facilitate the filing of any document or the taking of reasonable action to assist the other parties hereto in complying with the terms hereof.
Without limiting the foregoing: the Company shall (x) execute and deliver the Indenture and engage a trustee under the Indenture and cause such trustee to execute and deliver the Indenture, and (y) the Company will execute and deliver to
the Purchasers the Registration Rights Agreement. 
 5.4.    Board Nominees and Observers. 

(a)    Following the Closing, the Purchasers shall, collectively, have the right to nominate, pursuant to the terms and
subject to the conditions of this Section 5.4, two nominees to the Board of Directors (the “Board Nominees”). Each such nominee shall not be prohibited from serving as a director pursuant to any applicable
law (including, the Exchange Act and the Clayton Antitrust Act of 1914, as amended) or rule or regulation of the SEC or any national securities exchange on which the Company’s Common Stock is listed or admitted to trading (the
“Qualification Requirement”); provided, that Messrs. Nathan Walton and Ronald Scott (the initial Board Nominees) shall be deemed to satisfy such Qualification Requirement. In addition, at least one such nominee shall satisfy
the independence requirements of the NYSE MKT or any other national securities exchange on which the Company’s Common Stock is listed or admitted to trading (other than for service on the audit committee), as determined in the good faith,
reasonable judgment of the Company. The Board of Directors and the appropriate committees of the Board of Directors shall conduct the consideration of the qualifications, suitability and independence of a Board Nominee, and make any determinations
with respect thereto, in a manner consistent with considerations and determinations in respect of other members of the Board of Directors. The Purchasers will take all necessary action to cause any nominee for Board Nominee to make himself or
herself reasonably available for interviews, to consent to such reference and background checks or other investigations and to provide such information (including information necessary to determine the nominee’s independence status under
various requirements and institutional investor guidelines as well as information necessary to determine any disclosure obligations of the Company) as the Board of Directors or its Nominating and Governance Committee may reasonably request;
provided, that in each such case, all interviews, investigations and information are generally required to be delivered to the Company by the outside directors of the Company. Provided that the Board Nominees then meet the Qualification
Requirement, the Company shall nominate (x) each Board Nominee for re-election as director at the end of each term of such Board Nominee in the event the Purchasers, together with their Affiliated
Entities, collectively, then Beneficially Own at least 15% of the outstanding Common Stock or (y) one Board Nominee for re-election as director at the end of the term of such Board Nominee in the event
the Purchasers, together with their Affiliated Entities, collectively, then Beneficially Own at least 5% but less than 15% of the outstanding Common Stock, in each case as part of the slate proposed by the Company that is included in the

  
 - 23 - 

 
proxy statement (or consent solicitation or similar document) of the Company relating to the election of the Board of Directors and will use its reasonable best efforts to cause the election of
such Board Nominee(s) to the Board of Directors (including providing the same level of support as is provided for other nominees of the Company to the Board of Directors). In the event that a Board Nominee ceases to be a member of the Board of
Directors and at such time another Board Nominee is still a member of the Board of Directors, so long as the Purchasers, together with their Affiliated Entities, collectively, Beneficially Own at least 15% of the outstanding Common Stock, the
Purchasers may select another person as a nominee for Board Nominee to fill the vacancy created thereby and, if the Board of Directors determines that such nominee meets the Qualification Requirement, such nominee shall become a Board Nominee and
shall be appointed to fill such vacancy. In the event that a Board Nominee ceases to be a member of the Board of Directors and at such time there are no other Board Nominee on the Board of Directors, so long as the Purchasers, together with their
Affiliated Entities, collectively, Beneficially Own at least 5% of the outstanding Common Stock, the Purchasers may select another person as a nominee for Board Nominee to fill the vacancy created thereby and, if the Board of Directors determines
that such nominee meets the Qualification Requirement, such nominee shall become a Board Nominee and shall be appointed to fill such vacancy. 

(b)    The Board Nominees shall be subject to the policies and requirements of the Company and its Board of Directors,
including the corporate governance guidelines of the Board of Directors and the Company’s Code of Ethics, in a manner consistent with the application of such policies and requirements to other members of the Board of Directors and in a manner
that does not discriminate against the Purchasers or their Affiliates. The Company shall compensate the Board Nominees, reimburse their expenses, indemnify them and provide the Board Nominees with director and officer insurance to the same extent it
compensates, reimburses, indemnifies and provides insurance for the outside members of the Board of Directors pursuant to its organizational documents, applicable law or otherwise. 

(c)    Subject to applicable law and the approval of the Board of Directors to the extent such approval is required by
law, which the Company will use its best efforts to obtain, at least one Board Nominee shall be entitled (but not be required) to sit as a member of each committee of the Board of Directors. 

(d)    Other than transfers to an Affiliate of the Purchasers (which shall not require the consent of the Company), the
rights of the Purchasers pursuant to this Section 5.4 shall be specific to the Purchasers and may not be transferred or assigned, in whole or in part, by the Purchasers directly or indirectly (including by way of direct or
indirect transfers of equity interests in such Persons) without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. Without limiting any other reason for the Company to withhold
consent, it will be deemed reasonable for the Company to withhold consent to the transfer or assignment of the rights of the Purchasers pursuant to this Section 5.4 to a Competitor. 

(e)    So long as the Purchasers, together with their Affiliated Entities, collectively, then Beneficially Own at least
5% of the outstanding Common Stock (including for this purpose all Conversion Shares issuable upon the Notes assuming such Notes were converted entirely into Common Stock), the Purchasers shall be entitled to appoint a number of observers

  
 - 24 - 

 
(the “Observers”) to the Board of Directors, who shall be reasonably acceptable to the Company, equal to the number of Board Nominees that the Purchasers are then entitled to
nominate, less the number of Board Nominees of the Purchasers that are then members of the Board of Directors. The Observers shall be permitted to attend and observe all meetings (other than executive sessions) of the Board of Directors, including
any committees of the Board of Directors. The Observers shall not have the right to vote on any matter that comes before the Board of Directors. The Observers shall receive copies of all written materials distributed to the Board of Directors and
shall receive notice of each meeting or action by written consent of the Board of Directors at the same time and in the same manner as notice is given to the Board of Directors. Notwithstanding the foregoing, the Company shall be entitled to
withhold any information from an Observer and exclude such Observer from any meeting, or any portion thereof, (i) if the Company reasonably determines that such withholding or exclusion is necessary to preserve attorney-client privilege, to
protect highly confidential competitively sensitive information or for other similar reasons, or (ii) if the Company believes in good faith that such Observer has a conflict of interest. The Observers shall execute a confidentiality agreement
in form and substance reasonably acceptable to the Company and such Observers with respect to the information and discussions to which the Observers will have access. 

(f)    All obligations of the Company pursuant to Sections 5.4(a), (b), (c) and
(e) shall terminate upon the first to occur of: (i) such time as the Purchasers, together with their Affiliated Entities, collectively, do not Beneficially Own at least 5% of the outstanding Common Stock, (ii) the Company sells
all or substantially all of its consolidated assets to an unaffiliated third party, (iii) any Person or “group” (as such term is used in Section 13 of the Exchange Act) (other than the Purchasers or any “group”
including the Purchasers), directly or indirectly, obtains Beneficial Ownership of 50% or more of the total outstanding voting power of the Voting Stock, (iv) the Company participates in any merger, consolidation or similar transaction unless
immediately following the consummation of such transaction the stockholders of the Company immediately prior to the consummation of such transaction continue to hold (in substantially the same proportion as their ownership of the Company’s
Voting Stock immediately prior to the transaction) more than 50% of all of the outstanding common stock or other securities entitled to vote for the election of directors of the surviving or resulting entity in such transaction or (v) the
Purchasers irrevocably waive and terminate all of its rights under this Section 5.4. In addition, the right of the Purchasers to nominate two nominees to the Board of Directors pursuant to Section 5.4(a) shall be
reduced to one nominee at such time as the Purchasers, together with their Affiliated Entities, collectively, do not Beneficially Own at least 15% of the outstanding Common Stock. 

5.5.    Board Composition. Subject to the terms of the Company’s existing 8.625% Series A Cumulative Preferred
Stock and 10.75% Series B Cumulative Preferred Stock as of the date hereof, for so long as the Purchasers have the right to nominate at least one person to the Board of Directors in accordance with Section 5.4, the Company
shall not, without the prior written consent of the Purchasers, increase the size of the Board of Directors in excess of eight (8) directors or decrease the size of the Board of Directors if such decrease would require the resignation of a
Board Nominee. 
 5.6.    Specific Performance. The Purchasers and the Company agree that irreparable damage
would occur and that the Company and the Purchasers, as applicable, would 

  
 - 25 - 

 
not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that money
damages or other legal remedies would not be an adequate remedy for any such failure to perform or breach. Accordingly, the Purchasers and the Company agree that in the event of any breach or threatened breach by the Company on the one hand and the
Purchasers on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company and the Purchasers, as applicable, shall without the necessity of proving the inadequacy of money damages or posting a bond or
other security be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms, provisions and covenants contained herein, this being in addition to any other remedy to
which they are entitled at law or in equity. 
 5.7.    Use of Proceeds. The Company shall use the proceeds from
the issuance of securities pursuant to this Agreement solely to repay all outstanding borrowings under the Revolving Credit Facility, redeem in full the Senior Secured Notes and for general corporate purposes. 

5.8.    PATRIOT Act. The Company shall use reasonable best efforts to provide all documentation at least two
business days prior to the Closing Date that the Purchasers or the Purchasers’ financing sources have reasonably determined is required by United States regulatory authorities under applicable “know your customer” and anti-money
laundering rules and regulations, including Title III of the U.S.A. PATRIOT Act of 2001 to the extent such documentation is requested by the Purchasers at least ten (10) business days prior to the Closing Date. 

5.9.    DTC. The Company will (i) cause the Notes to be eligible for inclusion in the book-entry settlement
system of The Depository Trust Company (the “DTC”) and (ii) comply with all of its obligation set forth in the representations letter (and related riders) of the Company to the DTC relating to such inclusion. 

5.10.    Preemptive Rights. 

(a)    From and after the Closing, for so long as the Purchasers, together with their Affiliated Entities, collectively,
Beneficially Own at least 10% of the outstanding Common Stock (including for this purpose all Conversion Shares issuable upon conversion of the Notes assuming such Notes were converted entirely into Common Stock at such time), if the Company
proposes to issue for cash Equity Securities of any kind, other than Excluded Stock, then, the Company shall: 

(i)    give written notice to each Purchaser (no less than five (5) business days prior to the closing of such
issuance or if the Company reasonably expects such issuance to be completed in less than five (5) business days, such shorter period, which shall be as long as commercially practicable (and in any event no less than three (3) business
days), required for the Purchasers to participate in such issuance) setting forth in reasonable detail (A) the designation and all of the terms and provisions of the Equity Securities proposed to be issued (the “Proposed
Securities”), including, where applicable, the voting powers, preferences and relative participating, optional or other special rights, and the qualification, limitations or 

  
 - 26 - 

 
restrictions thereof and interest rate and maturity; (B) the price and other terms of the proposed sale of such securities; (C) the amount of such securities proposed to be issued; and
(D) such other information as the any Purchaser may reasonably request in order to evaluate the proposed issuance; and 

(ii)    offer to issue and sell to each of the Purchasers, on such terms as the Proposed Securities are issued, up to
that portion of the Proposed Securities equal to a percentage determined by dividing (A) the number of shares of Common Stock such Purchasers Beneficially Own (on an as-converted basis) by (B) the
total number of shares of Common Stock then outstanding (on an as-converted basis) (the “Pro Rata Share”). 

(b)    The Purchasers must exercise their purchase rights hereunder within four (4) business days after receipt of
such notice from the Company, or if the Company reasonably expects such issuance to be completed in less than four (4) business days, such shorter period, which shall be as long as practicable (and in any event no less than three
(3) business days after receipt of notice from the Company), required for the Purchasers to participate in such issuance. If the Company offers two (2) or more securities in units to the other participants in the offering, the Purchasers
must purchase such units as a whole and will not be given the opportunity to purchase only one (1) of the securities making up such unit. The closing of the exercise of such subscription right shall take place simultaneously with the closing of
the sale of the Proposed Securities giving rise to such subscription right. 
 (c)    Upon the expiration of the
offering period described above, the Company will be free to sell such Proposed Securities that the Purchasers have not elected to purchase during the ninety (90) days following such expiration on terms and conditions no more favorable to the
purchasers thereof than those offered to the Purchasers in the notice delivered in accordance with Section 5.10(a)(i). Any Proposed Securities offered or sold by the Company after such 90-day period
must be reoffered to the Purchasers pursuant to this Section 5.10. 
 (d)    In the case of
any underwritten offering conducted by the Company pursuant to a registration statement under the Securities Act or the exemption from registration in Rule 144A of the Securities Act that would otherwise be subject to this
Section 5.10, in lieu of the procedures set forth in clauses (a) through (c) above, the Company shall cause its lead underwriter to (i) deliver written notice to the Purchasers regarding the expected range of
pricing in such offering, with the highest expected price in such range not to exceed 110% of the lowest expected price in such range, at least three (3) business days prior to the day of pricing of such offering and the other information
contemplated by Section 5.10(a)(i)(A), (C) and (D), (ii) solicit an order from each Purchaser on the day of pricing in the same way orders are solicited from other investors on the day of pricing and
(iii) fill any such order submitted by a Purchaser, at the pricing of such offering and subject to any price caps or volume restrictions specified by such Purchaser, up to the relevant Purchaser’s Pro Rata Share of such offering (including
any Green Shoe option contemplated thereby). For the avoidance of doubt, the Company shall be liable for any breach of these procedures by its lead underwriter. In the event the Purchasers do not submit one or more orders as contemplated by
clause (iii) above, the Company will be free to sell such Proposed Securities in such underwritten offering on terms and conditions no more favorable to the purchasers thereof than those quoted to the Purchasers by the lead underwriter on the
day of pricing, as contemplated by Section 5.10(d)(ii). Any Proposed Securities offered or sold by the Company in any subsequent underwritten offering must be reoffered to the Purchasers pursuant to this Section 5.10(d). 

  
 - 27 - 

 (e)    The election by any Purchaser not to exercise its subscription rights
under this Section 5.10 in any one instance shall not affect their right as to any subsequent proposed issuance. Any sale of Equity Securities by the Company without first giving the Purchasers the rights described in this
Section 5.10 shall be void and of no force and effect. 
 (f)    Purchasers acknowledge that
delivery of any notice delivered in accordance with Section 5.10(a)(i) or any notice of any lead underwriter delivered in accordance with Section 5.10(d), and the information provided in any such notice, shall be treated as
Confidential Information (as defined in Section 10.9). 
 (g)    Notwithstanding anything to
the contrary in this Agreement, the rights of Purchasers under this Section 5.10 (i) shall terminate at the first time following Closing that Purchasers, together with their Affiliated Entities, collectively, cease to
Beneficially Own at least 10% of the outstanding Common Stock (including for this purpose all Conversion Shares issuable upon conversion of the Notes assuming such Notes were converted entirely into Common Stock) and (ii) shall be limited to
the right to purchase only such amount of Proposed Securities as may be permitted without requiring the approval of stockholders of the Company under any then applicable rule of the primary securities exchange on which the Common Stock is traded.

 (h)    Other than transfers to an Affiliate of the Purchasers in connection with the transfer of Notes or Firm
Shares to such Affiliate (which shall not require the consent of the Company), the rights of the Purchasers pursuant to this Section 5.10 shall be specific to the Purchasers and may not be transferred or assigned, in whole
or in part, by the Purchasers directly or indirectly (including by way of direct or indirect transfers of equity interests in such Persons) without the prior written consent of the Company, which consent may be withheld, conditioned or delayed in
its sole and absolute discretion. 
 5.11.    Standard of Care; Corporate Opportunities. 

(a)    To the fullest extent permitted by the General Corporation Law of the State of Delaware, the Company acknowledges
that: (i) the Purchasers (subject to the proviso below) and each of their Affiliates, (ii) the Board Nominees and the Observers and (iii) any other employee, consultant, officer or director of the Company specifically designated by
the Purchasers or one of their respective Affiliates (collectively, the “Exempt Persons”) shall not make any representations or warranties, express or implied, in respect of the services to be provided by the Purchasers nor any of
their respective Affiliates hereunder or by virtue of holding Equity Securities in the Company. In no event will any Exempt Person be liable to the Company or any of its Affiliates for any act, alleged act, omission or alleged omission relating to
the actions of such Exempt Person in his or her or its capacity as a director, observer, employee or stockholder of the Company that does not constitute willful misconduct or bad faith of such Exempt Person. 

  
 - 28 - 

 (b)    In recognition that the Exempt Persons have access to information
about the Company that will enhance such persons’ knowledge and understanding of the industries in which the Company operates, and currently have and will in the future have or will consider acquiring, investments in numerous companies with
respect to which each Exempt Person may serve as an advisor, a director or in some other capacity, and in recognition that the Exempt Persons have myriad duties to various investors and partners, and in anticipation that the Company, on the one
hand, and the Exempt Persons, on the other hand, may engage in the same or similar activities or lines of business and have an interest in the same areas of corporate opportunities, and in recognition of the benefits to be derived by the Company
hereunder and in recognition of the difficulties which may confront any advisor who desires and endeavors fully to satisfy such advisor’s duties in determining the full scope of such duties in any particular situation, the provisions of this
Section 5.11(b) are set forth to regulate, define and guide the conduct of certain affairs of the Company as they may involve the Exempt Persons, and, except as the Exempt Persons may otherwise agree in writing after the date hereof: 

(i)    the Exempt Persons will have the right (and none of the Exempt Persons will be liable to the Company or any of its
shareholders or Affiliates as a result of the right of the Exempt Persons): (A) to directly or indirectly engage in any business (including, any business activities or lines of business that are the same as or similar to those pursued by, or
competitive with, the Company), (B) to directly or indirectly do business with any client or customer of the Company, (C) to take any other action that the Exempt Persons believes in good faith is necessary to or appropriate to fulfill its
obligations as described in the first sentence of this Section 5.11(b) to third parties and (D) not to communicate or present potential transactions, matters or business opportunities to the Company, and to pursue, directly or
indirectly, any such opportunity for itself, and to direct any such opportunity to another person or entity; 

(ii)    the Exempt Persons will have no duty (contractual or otherwise) to communicate or present any corporate
opportunities to the Company or any of its Affiliates (including potential opportunities in the oil and gas industry generally or that relate directly or indirectly to the Company’s past, current or future lines of business) or to refrain from
any actions specified in Section 5.11(b)(i), and the Company, on its own behalf and on behalf of its Affiliates, hereby renounce and waive any right to require the Exempt Persons to act in a manner inconsistent with the provisions of this
Section 5.11; and 
 (iii)    there is no restriction on the Exempt Persons from using such
knowledge and understanding in making investment, voting, monitoring, governance or other decisions relating to other entities or securities. 

5.12.    No Purchaser Short Positions. From and after the date of this Agreement and for so long as Purchasers,
together with their Affiliated Entities, collectively, Beneficially Own at least 5% of the outstanding any Common Stock (including for this purpose all Conversion Shares issuable upon conversion of the Notes assuming such Notes were converted
entirely into Common Stock at such time) and have at least one director nominee or designee on the Board of Directors, each Purchaser shall refrain from executing or creating, either directly or indirectly including through the use of derivative
securities and trading instruments or through positions created by any of its Affiliated Entities, a short sale trade or a short trading position in the Common Stock or the Notes.

9.    Indemnification of the Purchasers. 

9.1.    General. The Purchasers, their Affiliates and their respective directors, officers, members, partners,

reasonable attorneys’ fees) (collectively, “Losses”) to which such Indemnified Persons may become subject as a result of, arising in connection with, or relating to any Action by any Person (including any stockholder of the
Company regardless of whether such Action is against a Purchaser) if such Action either (x) alleges a breach of any duty, right or other obligation by the Company and/or any officers or directors of any of the foregoing in such capacity or
(y) involves a claim or cause of action with respect to which the Indemnified Persons would not have any liability unless there were a breach of any duty, right or other obligation by the Company and/or any officers or directors of any of the
foregoing in such capacity, in each case with respect to any of the transactions contemplated by this Agreement; provided that the Company will not be liable to indemnify any Indemnified Person for any such Losses to the extent that such Losses
(w) have resulted from an Action by the Company against the Purchasers in connection with such Purchasers’ breach of this Agreement, (x) are as a result of an Action brought against the Purchasers by any Person who is a limited
partner of, or other investor in, such Purchasers in such Person’s capacity as a limited partner of, or other investor in, such Purchasers, (y) as a result of any Action brought against the Purchasers or their Affiliates by any Person
providing financing to the Purchasers or their Affiliates in connection with the Purchasers’ or their Affiliates investment in the Securities. 

9.2.    Claims; Disputes. Each Indemnified Person shall give the Company prompt written notice (an
“Indemnification Notice”) of any third party Action it has actual knowledge of that might give rise to Losses, which notice shall set forth a description of those elements of such Action of which such Indemnified Person has
knowledge; provided, that any delay or failure to give such Indemnification Notice shall not affect the indemnification obligations of the Company hereunder except to the extent the Company is materially prejudiced by such delay or failure. 

9.3.    Opportunity to Defend Third Party Claims. The Company shall have the right, exercisable by written notice
to the applicable Indemnified Person(s) within thirty (30) days of receipt of the applicable Indemnification Notice, to select counsel to defend and control the defense of any third party claim set forth in such Indemnification Notice; provided
that the Company shall not be entitled to so select counsel or control the defense of any claim if (i) such claim seeks primarily non-monetary or injunctive relief against the Indemnified Person or
alleges any violation of criminal law, (ii) the Company does not, subsequent to its assumption of such defense in accordance with this Section 9.3, conduct the defense of the such claim actively and diligently,
(iii) such claim includes as the named parties both the Company and the applicable Indemnified Person(s) and such Indemnified Persons reasonably determine upon the advice of counsel that representation of all such Indemnified Persons by the
same counsel would be prohibited by applicable codes of professional conduct, or (iv) in the event that, based on the 

  
 - 34 - 

 
reasonable advice of counsel for the applicable Indemnified Person(s), there are one or more material defenses available to the applicable Indemnified Person(s) that are not available to the
Company. If the Company does not assume the defense of any third party claim in accordance with this Section 9.3, the applicable Indemnified Person(s) may continue to defend such claim at the sole cost of the Company and
the Company may still participate in, but not control, the defense of such third party claim at the Company’s sole cost and expense. 

9.4.    Settlement. No Indemnified Person shall consent to a settlement of, or the entry of any judgment arising
from, any such claim, without the prior written consent of the Company (such consent not to be unreasonably withheld, conditioned or delayed). Except with the prior written consent of the applicable Indemnified Person(s) (such consent not to be
unreasonably withheld, conditioned or delayed), the Company, in the defense of any such claim, shall not consent to the entry of any judgment or enter into any settlement that (i) provides for injunctive or other nonmonetary relief affecting
any Indemnified Person; (ii) does not include as an unconditional term thereof the giving by each claimant or plaintiff to each such Indemnified Person(s) of an unconditional release of such Indemnified Person(s) from all liability with respect
to such Action; or (iii) includes any admission of fault or culpability or a failure to act by or on behalf of any Indemnified Person. In any such third party claim where the Company has assumed control of the defense thereof, the Company shall
keep the applicable Indemnified Person(s) informed as to the status of such claim at all stages thereof (including all settlement negotiations and offers), promptly submit to such Indemnified Person(s) copies of all pleadings, responsive pleadings,
motions and other similar legal documents and paper received or filed in connection therewith, permit such Indemnified Person(s) and their respective counsels to confer with the Company and its counsel with respect to the conduct of the defense
thereof, and permit such Indemnified Person(s) and their respective counsel(s) a reasonable opportunity to review all legal papers to be submitted prior to their submission.

or claim the same to the extent permitted by applicable law; 
 (iii)    agrees that service of process in any such
action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the party, as the case may be, at its address set forth in
Section 10.3 or at such other address of which the other party shall have been notified pursuant thereto; 

  
 - 37 -

 (vi)    agrees that to the extent that such party has or hereafter may acquire any

CORPORATE LEGAL OPINION MATTERS 
  

	1.	The Company is validly existing as a corporation and in good standing under the laws of the State of Delaware, with the corporate power and authority to own or lease, as the case may be, and to operate its properties
and conduct the businesses in which it is currently engaged; 

  

	2.	The Firm Shares have been duly authorized by all necessary corporate action of the Company and, when issued and delivered by the Company to the Purchasers upon payment therefor in accordance with the Purchase Agreement,
will be validly issued, fully paid and non-assessable; 

  

	3.	The equity holders of the Company have no preemptive rights with respect to the Firm Shares under federal law, the General Corporation Law of the State of Delaware (the “DGCL”) or any agreement filed as
an exhibit to the Company’s SEC Reports to which the Company is a party or by which the Company may be bound; 

  

	4.	The Purchase Agreement, the Registration Rights Agreement and the Indenture have been duly authorized, executed and delivered by the Company; the Purchase Agreement, the Registration Rights Agreement and the Indenture
constitute the legal, valid and binding obligations of the Company, enforceable in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’
rights generally or by general principles of equity, including principles of commercial reasonableness, fair dealing and good faith; 

  

	5.	The Notes have been duly authorized, executed and delivered by the Company; the Notes, when duly authenticated as provided in the Indenture and paid for as provided in the Purchase Agreement, will constitute the valid
and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’ rights
generally or by general principles of equity, including principles of commercial reasonableness, fair dealing and good faith. 

  

	6.	The shares of Common Stock initially issuable upon conversion of the Notes (assuming, for this purpose, that the Notes are converted solely into shares of Common Stock (and cash in lieu of fractional shares) and are
converted at the maximum “make-whole” conversion rate provided for in the Indenture) have been duly authorized and reserved for issuance upon such conversion and, assuming the Notes have been delivered to and paid for by the Purchasers in
accordance with the terms of the Purchase Agreement, when such shares of Common Stock are issued upon conversion of the Notes, will be validly issued, fully paid and nonassessable; and the issuance of such shares of Common Stock upon conversion of
the Notes will not violate any preemptive or similar rights pursuant to (i) any agreement or instrument filed as an exhibit to the Company’s SEC Reports, (ii) the Certificate of Incorporation or Bylaws of the Company in effect on the
date hereof or (iii) the DGCL. 

	7.	No approval, authorization, license, registration, qualification, decree, consent or order under any federal law, the DGCL, the laws of the State of New York or approval, authorization, license, registration,
qualification, decree, consent or order of or filing with any U.S. federal, New York or Delaware governmental or regulatory commission, board, body, authority or agency, is necessary or required in connection with the issuance and sale of the
Securities or the consummation by the Company of the transactions contemplated by the Purchase Agreement, the Registration Rights Agreement, the Indenture and the Securities except for such consents, approvals, authorizations, registrations or
qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Securities by the Purchasers (as to which we express no opinion) and except that we express no opinion in this
paragraph with respect to federal securities laws. 

  

	8.	The execution, delivery and performance of the Purchase Agreement, the Registration Rights Agreement, the Indenture and the Securities by the Company, the issuance and sale of the Securities and the consummation of the
transactions contemplated by the Purchase Agreement, the Registration Rights Agreement, the Indenture and the Securities do not and will not result in any breach or violation of or constitute a default under (nor constitute any event which, with
notice, lapse of time or both, would result in any breach or violation of or constitute a default under or give the holder of any indebtedness (or a person acting on such holder’s behalf) the right to require the repurchase, redemption or
repayment of all or a part of such indebtedness under) (or result in the creation or imposition of a lien, charge or encumbrance on any property or assets of the Company or any Subsidiary pursuant to) (i) any agreement or instrument filed as an
exhibit to the Company’s SEC Reports, (ii) the United States federal laws, the DGCL, the laws of the State of New York, in each case, of a kind typically applicable to such transactions, or (iii) any decree, judgment or order
applicable to the Company or any of its respective properties, which decree, judgment or order is known by us; provided that with respect to clause (ii) above, we state no opinion as to any federal or state securities or Blue Sky laws or
federal or state antifraud laws, rules or regulations. 

  

	9.	Assuming the accuracy of the representations and warranties contained in the Purchase Agreement, the sale and issuance of the Securities by the Company to the Purchasers solely in the manner contemplated by the Purchase
Agreement are exempt from the registration requirements of the Securities Act and it is not necessary to qualify the Indenture under the Trust Indenture Act of 1939, as amended; provided, that, we express no opinion as to any subsequent sale or
resale; and 

  

	10.	The Company is not now and, after giving effect to the issuance and sale of the Securities by the Company and the applications of the proceeds therefrom, the Company will not be required to register as an
“investment company” within the meaning of the Investment Company Act.

 Exhibit 10.2 

AMENDMENT NO. 1 
 TO THE

 SECURITIES PURCHASE AGREEMENT 

This AMENDMENT NO. 1 (this “Amendment”), dated as of March 3, 2017, to the Securities Purchase Agreement, dated
as of February 16, 2017 (the “Agreement”), by and among Gastar Exploration Inc., a Delaware corporation (the “Company”) and each of the purchasers listed on Schedule I thereto (the
“Purchasers”). The Company and the Purchasers are each referred to individually as a “Party” and are collectively referred to as the “Parties.” 

R E C I T A L S 
 WHEREAS,
the Parties desire to amend certain provisions of the Agreement pursuant to Section 10.12 thereof, as more particularly set forth in this Amendment. 

A G R E E M E N T S 
 NOW,
THEREFORE, in consideration of the mutual agreements set forth in the Agreement and this Amendment, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows:

 ARTICLE I 

AMENDMENT 

1.1    Defined Terms; References. Unless otherwise specifically defined in this Amendment, each term
used herein that is defined in the Agreement has the meaning assigned to such term in the Agreement, and each reference to a specific Exhibit, Section or Article shall refer to the particular Exhibit, Section or Article in the Agreement. Each
reference to “hereof,” “hereunder,” “herein,” “hereby” and each other similar reference contained in the Agreement shall refer, from and after the date of this Amendment, to the Agreement as amended by this
Amendment. 
 1.2    Amendment to Section 1. The definition of
“Beneficially Own,” “Beneficially Owned,” or “Beneficial Ownership” set forth in Section 1 is hereby amended and restated in its entirety as follows: 

“ “Beneficially Own,” “Beneficially Owned,” or “Beneficial Ownership” shall have the
meaning set forth in Rule 13d-3 of the rules and regulations promulgated under the Exchange Act; provided, that for purposes of this Agreement the words “within sixty days” in Rule 13d-3(d)(1)(i) shall not apply, to the effect that a Person shall be deemed to be the beneficial owner of a security if that Person has the right to acquire beneficial ownership of such security at any time;
provided further that, solely for purposes of Section 5.4(a), Section 5.4(f)(i) and the last sentence of Section 5.4(f), Rule 13d-3(d)(1) shall not apply, to
the effect that a Person shall not be deemed to be the beneficial owner of a security if that Person only has the right to acquire beneficial ownership of such security.” 

 1.3    Amendment of Section 5.4(a). Section 5.4(a) is
hereby amended and restated in its entirety as follows: 
 “Following the Closing, the Purchasers shall, collectively, have the right to
nominate, pursuant to the terms and subject to the conditions of this Section 5.4, two nominees to the Board of Directors (the “Board Nominees”). Each such nominee shall not be prohibited from serving as a
director pursuant to any applicable law (including, the Exchange Act and the Clayton Antitrust Act of 1914, as amended) or rule or regulation of the SEC or any national securities exchange on which the Company’s Common Stock is listed or
admitted to trading (the “Qualification Requirement”); provided, that Messrs. Nathan Walton and Ronald Scott (the initial Board Nominees) shall be deemed to satisfy such Qualification Requirement. In addition, at least one
such nominee shall satisfy the independence requirements of the NYSE MKT or any other national securities exchange on which the Company’s Common Stock is listed or admitted to trading (other than for service on the audit committee), as
determined in the good faith, reasonable judgment of the Company. The Board of Directors and the appropriate committees of the Board of Directors shall conduct the consideration of the qualifications, suitability and independence of a Board Nominee,
and make any determinations with respect thereto, in a manner consistent with considerations and determinations in respect of other members of the Board of Directors. The Purchasers will take all necessary action to cause any nominee for Board
Nominee to make himself or herself reasonably available for interviews, to consent to such reference and background checks or other investigations and to provide such information (including information necessary to determine the nominee’s
independence status under various requirements and institutional investor guidelines as well as information necessary to determine any disclosure obligations of the Company) as the Board of Directors or its Nominating and Governance Committee may
reasonably request; provided, that in each such case, all interviews, investigations and information are generally required to be delivered to the Company by the outside directors of the Company. Provided that the Board Nominees then meet the
Qualification Requirement, the Company shall nominate (x) each Board Nominee for re-election as director at the end of each term of such Board Nominee in the event the Purchasers, together with their
Affiliated Entities, collectively, then Beneficially Own at least 15% of the total outstanding voting power of the Voting Stock or (y) one Board Nominee for re-election as director at the end of the term
of such Board Nominee in the event the Purchasers, together with their Affiliated Entities, collectively, then Beneficially Own at least 5% but less than 15% of the total outstanding voting power of the Voting Stock, in each case as part of the
slate proposed by the Company that is included in the proxy statement (or consent solicitation or similar document) of the Company relating to the election of the Board of Directors and will use its reasonable best efforts to cause the election of
such Board Nominee(s) to the Board of Directors (including providing the same level of support as is provided for other nominees of the Company to the Board of Directors). In the event that a Board Nominee ceases to be a member of the Board of
Directors and at such time another Board Nominee is still a member of the Board of Directors, so long as the Purchasers, together with their Affiliated Entities, collectively, Beneficially Own at least 15% of the total outstanding voting power of
the Voting Stock, the Purchasers may select another person as a nominee for Board Nominee to fill the vacancy created thereby and, if the Board of Directors determines that such nominee 

  
 2 

 
meets the Qualification Requirement, such nominee shall become a Board Nominee and shall be appointed to fill such vacancy. In the event that a Board Nominee ceases to be a member of the Board of
Directors and at such time there are no other Board Nominee on the Board of Directors, so long as the Purchasers, together with their Affiliated Entities, collectively, Beneficially Own at least 5% of the total outstanding voting power of the Voting
Stock, the Purchasers may select another person as a nominee for Board Nominee to fill the vacancy created thereby and, if the Board of Directors determines that such nominee meets the Qualification Requirement, such nominee shall become a Board
Nominee and shall be appointed to fill such vacancy.” 
 1.4    Amendment of Section 5.4(f). Section
5.4(f) is hereby amended and restated in its entirety as follows: 
 “All obligations of the Company pursuant to Sections
5.4(a), (b), (c) and (e) shall terminate upon the first to occur of: (i) such time as the Purchasers, together with their Affiliated Entities, collectively, do not Beneficially Own at least 5% of the total
outstanding voting power of the Voting Stock, (ii) the Company sells all or substantially all of its consolidated assets to an unaffiliated third party, (iii) any Person or “group” (as such term is used in Section 13 of the
Exchange Act) (other than the Purchasers or any “group” including the Purchasers), directly or indirectly, obtains Beneficial Ownership of 50% or more of the total outstanding voting power of the Voting Stock, (iv) the Company
participates in any merger, consolidation or similar transaction unless immediately following the consummation of such transaction the stockholders of the Company immediately prior to the consummation of such transaction continue to hold (in
substantially the same proportion as their ownership of the Company’s Voting Stock immediately prior to the transaction) more than 50% of all of the outstanding common stock or other securities entitled to vote for the election of directors of
the surviving or resulting entity in such transaction or (v) the Purchasers irrevocably waive and terminate all of its rights under this Section 5.4. In addition, the right of the Purchasers to nominate two nominees to
the Board of Directors pursuant to Section 5.4(a) shall be reduced to one nominee at such time as the Purchasers, together with their Affiliated Entities, collectively, do not Beneficially Own at least 15% of the total outstanding voting
power of the Voting Stock.” 
 1.5    Amendment of Exhibit A. The definition of “Requisite
Stockholder Approval” set forth in Section 1.01 of Exhibit A is hereby amended and restated in its entirety as follows: 
 “
“Requisite Shareholder Approval” means any and all stockholder approvals that would be required under the listing standards of The NYSE MKT to permit all outstanding Notes to be converted into shares of Common Stock (assuming
Physical Settlement at the maximum Conversion Rate referred to in Section 5.07(A)).”
