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)).”
