NOW, THEREFORE, in consideration of the foregoing premises, the mutual covenants and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

(a) Purchase and Sale. Each Seller hereby sells, conveys, assigns and delivers to the Company at the Closing (as defined below), free and clear of all Encumbrances and Transfer Restrictions (each as defined in Section 6 of this Agreement), other than Transfer Restrictions under applicable securities laws or as may be contained in the documents issuing such securities to such Seller, and the Company hereby purchases, acquires and accepts from each Seller at the Closing, the Transaction Securities, together with all rights to receive dividends, interest or other amounts with respect to the Transaction Securities and all other rights relating thereto (the “Transaction”).

(b) Closing. The closing of the Transaction (the “Closing”) shall take place on a date to be determined by the Company (in its sole discretion), but no later than the third (3rd) Business Day immediately following the date hereof (the “Closing Date”) at the offices of Weil, Gotshal & Manges LLP, 767 Fifth Avenue, New York, New York 10153. The Company shall notify each Seller of the date of the Closing as promptly as practicable.

(c) Purchase Price. At the Closing, (i) the Company shall pay, or cause to be paid, to each Seller, an aggregate amount in cash as set forth opposite such Seller’s name on Annex A (the “Purchase Price”), and (ii) each such Seller shall deliver, or cause to be delivered, to the Company, the Transaction Securities, such delivery to be effected in accordance with Section 5(a) of this Agreement.

Section 2. Representations and Warranties of the Seller. Each Seller hereby represents and warrants to the Company on the date hereof and as of the Closing Date as follows:

(a) Capacity; Due Authorization and Execution; Enforceability. Each such Seller has the power and capacity to enter into this Agreement and to consummate the Transaction. The execution, delivery, and performance by such Seller of this Agreement and the consummation by such Seller of its obligations hereunder have been duly authorized by all necessary action by such Seller. This Agreement has been duly and validly executed and delivered by each Seller and constitutes the legal, valid and binding obligation of such Seller, enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws from time to time in effect that affect creditors’ rights generally, and by legal and equitable limitations on the availability of specific remedies. Any person signing this Agreement on behalf of such Seller has been duly and validly authorized and empowered to do so and has the authority to bind such Seller and to effectuate the transactions contemplated by this Agreement.

(b) No Contravention; No Conflict. The execution, delivery and performance by such Seller of this Agreement and consummation by such Seller of the Transaction do not and will not (i) violate any decree or judgment of any court or other governmental authority applicable to or binding on such Seller or its affiliates, (ii) violate any provision of any statute, rule or regulation applicable to such Seller or its affiliates, (iii) conflict with, or result in any violation of, any provision of any organizational document of such Seller or (iv) violate or result in a default under any material contract to which such Seller, its affiliates or any of their respective assets or properties are bound. No consent or approval of, or filing by such Seller with, any governmental authority or other person not a party hereto is required for the execution, delivery and performance by such Seller of this Agreement or the consummation of the Transaction by such Seller, other than routine securities law filings.

(c) Beneficial Ownership; No Encumbrances; Transfer Restrictions. Each Seller is the sole record and beneficial owner of the Transaction Securities set forth opposite its name on Annex A hereto, free and clear of any Encumbrances, and upon the transfer of the Transaction Securities to the Company, the Company shall acquire good title thereto, free and clear of any Encumbrances or Transfer Restrictions, other than Transfer Restrictions arising solely under applicable securities laws or as may be contained in the documents issuing such securities to such Seller. The Transaction Securities constitute 100% of the Common Stock, Preferred Stock and Warrants owned by each Seller and managed by Coliseum Capital Management, LLC (“CCM”) pursuant to an investment management agreement. CCM and its affiliates do not own or manage any accounts that own any other securities convertible into, or rights to acquire, any Transaction Securities.

(d) Information. Each Seller acknowledges that the Company, at the time of the Transaction, possesses a significant amount of Information not known to the Seller. Each Seller acknowledges that it has not requested the Company to disclose, and the Company has not disclosed, such Information to such Seller. Such Information, if known, might affect such Seller’s decision to enter into this Agreement and perform its terms, and/or the price at which such Seller would be willing to sell the Transaction Securities.

(e) Seller’s Information and Investment Experience and Sophistication. Each Seller, by reason of, among other things, the Seller’s business, investment and financial experience and sophistication, acknowledges that it is capable of evaluating the merits and risks of the Transaction and of protecting its own interests in connection with the Transaction. Each Seller is an experienced and sophisticated purchaser and seller of securities of various types and kinds, including but not limited to securities similar to and/or identical to the Transaction Securities.

(f) Required Protections. Each Seller wishes to enter into the Transaction for such Seller’s own business and investment purposes. Each Seller acknowledges that the Company would not enter into the Transaction with such Seller in the absence of the protections afforded to the Company by the Seller’s representations, warranties and agreements set forth in this Section 2 and the releases and waivers set forth in this Section 2 and elsewhere in this Agreement, and that such Seller is providing such representations, warranties, agreements, releases and waivers contained in this Agreement as a material and necessary inducement to the Company to consummate the Transaction (without which the Company would not consummate the Transaction).

(g) Independent Evaluation; Big-Boy Representations. Each Seller has conducted an independent evaluation of the Transaction Securities to determine whether to engage in the Transaction and has advised the Company that it intends to base its determination to proceed solely on publicly available information, even if there is a material discrepancy between publicly available information and Information. Each Seller is voluntarily assuming all risks associated with any Information and expressly warrants and represents that (x) such Seller disclaims the existence of or its reliance on, any representation by the Company concerning any Information and (y) such Seller is not relying on any disclosure or non-disclosure made or not made, or the completeness thereof, in connection with or arising out of the sale of the Transaction Securities, and therefore has no claims against the Company with respect thereto. If any such claim may exist, such Seller, recognizing its disclaimer of reliance and the Company’s reliance on such disclaimer as a condition to entering into this Agreement, covenants and agrees not to assert any such claim (and hereby waives any such claim) against the Company or any of the Company’s officers, directors, shareholders, partners, representatives, agents or affiliates. Each Seller further represents and acknowledges that: (i) it is an accredited investor (as defined in Rule 501(a) of Regulation D promulgated under the Securities Act of 1933), with sufficient knowledge and experience in transactions comparable to the Transaction to evaluate the merits and risks of this Agreement; (ii) it is selling the Transaction Securities solely for its own account; and (iii) the Company is relying upon such acknowledgements and representations as a condition to entering into this Agreement.

(h) Review with Counsel and Other Advisors. Each Seller has had the opportunity to consult with such Seller’s own counsel and financial and other advisors with respect to this Agreement, the terms hereof and the transactions to be consummated hereunder and has executed and delivered this Agreement freely and voluntarily.

(i) Sole Representations or Warranties. Each Seller acknowledges that the Company is not making any representations or warranties to such Seller, and such Seller is not relying on any statements, whether oral or written, which may have been made at any time by the Company or on the Company’s behalf, except for those representations and warranties of the Company expressly set forth in Section 3 of this Agreement.

Section 3. Representations, Warranties and Agreements of the Company. The Company hereby represents and warrants to each Seller on the date hereof and as of the Closing Date as follows:

The execution, delivery, and performance by the Company of this Agreement and the consummation by the Company of its obligations hereunder have been duly authorized by all necessary action by the Company. This Agreement has been duly and validly executed and delivered by the Company and constitutes the legal, valid and binding obligation of the Company, enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws from time to time in effect that affect creditors’ rights generally, and by legal and equitable limitations on the availability of specific remedies. Any person signing this Agreement on behalf of the Company has been duly and validly authorized and empowered to do so and has the authority to bind the Company, as the case may be, and to effectuate the transactions contemplated by this Agreement.

(b) No Contravention; No Conflict.
