RECITALS

In accordance with the terms and conditions of this Agreement and pursuant to exemptions from registration under the Securities Act of 1933, as amended (the “Securities Act”), the Company has agreed to issue and sell, and each Purchaser has agreed, severally and not jointly, to purchase from time to time a number of shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), and a warrant to purchase a number of shares of Common Stock (the “Warrant”, and together with all such warrants being issued to Purchasers under this Agreement, the “Warrants”), each as set forth opposite such Purchaser’s name on Schedule I to this Agreement.

NOW THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and each Purchaser hereby agree as follows:

1. PURCHASE AND SALE

(a) Authorization of Shares. The Company has authorized (i) the sale and issuance to the Purchasers of the shares of Common Stock, (ii) the sale and issuance to the Purchasers of the Warrants, and (iii) the issuance of shares of Common Stock to be issued upon exercise of the Warrants (the “Warrant Shares”).

(b) Purchase of Shares and Warrant. At each Closing, the Company shall issue and sell to each Purchaser, and each Purchaser shall, severally and not jointly, purchase from the Company, upon the terms and subject to the conditions set forth in this Agreement, (i) the number of shares of Common Stock set forth opposite such Purchaser’s name on Schedule I to this Agreement (the “Shares”) and (ii) a Warrant to purchase the number of shares of Common Stock set forth opposite such Purchaser’s name on Schedule I to this Agreement, for an aggregate purchase price as set forth opposite such Purchaser’s name on Schedule I to this Agreement (the “Purchase Price”), based on a purchase price per Share of $0.2745 (the “Per Share Purchase Price”).

2. CLOSINGS

(a) Initial Closing. The date and time of the initial Closing of the purchase and sale of the Shares and the Warrants (the “Initial Closing”) shall occur on May 17, 2013 at 12:00 p.m. Boston time, at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., Xxx Xxxxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx, 00000 (subject to the satisfaction or waiver of the conditions set forth in Subsections (d) and (f) of this Section 2), or at such other location, date and time as may be agreed upon between the Company and the Purchasers (the “Initial Closing Date”).

(b) Subsequent Closings.

(i)

Each Purchaser at the Initial Closing shall have the option, exercisable in its sole and exclusive discretion at any time and from time to time following the date of the Shareholder Approval of Increase in Authorized Shares (as defined in Section 7(a) below) and on or before June 30, 2014 (the “Expiration Date”), to purchase (and upon receipt of a Demand Notice (as defined below) from a Purchaser, the Company must sell) at one or more subsequent Closings on or before the Expiration Date (each such Closing, a “Subsequent Closing”), on the same terms and conditions as those contained in this Agreement, additional Shares and additional Warrants in an aggregate amount not to exceed the number of Shares and the number of Warrant Shares set forth opposite such Purchaser’s name under the heading “Subsequent Closings” on Schedule I hereto. Any Purchaser electing to purchase additional Shares and an additional Warrant at a Subsequent Closing shall provide written notice thereof to the Company, stating the number of additional Shares to be purchased and the number of Warrant Shares to be subject to the accompanying Warrant (which shall equal seventy-five percent (75%) of the number of additional Shares to be purchased at such Subsequent Closing), duly executed by such Purchaser and delivered to the Company in accordance with Section 9(d) (the “Demand Notice”). Following its delivery of a Demand Notice to the Company (and subject to the satisfaction or waiver of the conditions set forth in Subsections (e) and (g) of this Section 2), such Purchaser shall purchase from the Company, and the Company shall issue and sell to such Purchaser, at the Per Share Purchase Price, the additional Shares and Warrant as set forth in the Demand Notice. Each Subsequent Closing shall occur at such location, date and time as may be agreed upon between the Company and the Purchaser exercising the Purchaser Demand (each, a “Subsequent Closing Date”). The Initial Closing and each Subsequent Closing may also be referred to in this Agreement as a “Closing,” and the Initial Closing Date and each Subsequent Closing Date may also be referred to in this Agreement as a “Closing Date.”

(ii)

In the event that a Purchaser does not purchase any portion of the additional Shares and Warrant Shares set forth opposite such Purchaser’s name under the heading “Subsequent Closings” on Schedule I hereto on or before the Expiration Date (a “Non-Participating Purchaser”), then the Company shall provide written notice of such non-participation to each participating Purchaser (each a “Participating Purchaser”). Within thirty (30) days following the Company’s delivery of such notice, each Participating Purchaser shall have the right, but not the obligation, to purchase its pro rata portion of any additional Shares and Warrant Shares allocated to a Non-Participating Purchaser. In addition, each Participating Purchaser shall have the right, but not the obligation, to oversubscription such that if any other Participating Purchaser fails to purchase its full pro rata portion of a Non-Participating Purchaser’s additional Shares and Warrant Shares, the other Participating Purchasers shall, among them, have the right to purchase up to the balance of the additional Shares and Warrant Shares not so purchased. If, as a result thereof, such oversubscriptions exceed the total number of additional Shares and Warrant Shares available in respect of such oversubscription right, the oversubscribing Participating Purchasers shall be cut back with respect to their oversubscriptions in accordance with their respective pro rata portion. For purposes of this Section 2(b)(ii), a Participating Purchaser’s pro rata portion is equal to the quotient obtained by dividing the total number of Shares purchased by such Participating Purchaser pursuant to this Agreement by the total number of Shares purchased by all Participating Purchasers pursuant to this Agreement.

(c) Form of Payment. On the applicable Closing Date, each Purchaser shall pay the Company the Purchase Price for the Shares and the Warrant to be issued and sold to such Purchaser on such Closing Date, by wire transfer of immediately available funds in accordance with the Company’s written wire instructions previously provided to the Purchasers, and the Company shall deliver to each Purchaser the original certificate or certificates representing the Shares and the original Warrant, duly executed on behalf of the Company and registered in the name of such Purchaser.

(a) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of Delaware, United States of America, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Delaware. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

(i) Survival. Subject to applicable statute of limitations, the representations and warranties contained herein shall survive the Closing and the delivery of the Securities hereunder.

(j) No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person or entity.

The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity or bond) associated with the issuance of such replacement Securities.

(l) Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein or in any other document referred to herein, and no action taken by any Purchaser pursuant hereof or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of this Agreement and the other documents referred to herein.

In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.
