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

ARTICLE I.

PAYMENT OF INTEREST AMOUNT AND EXCHANGE

Section 1.01. Payment of Interest Amount. Substantially concurrently with the execution and delivery of this Agreement by the Parties, the Borrower shall pay to each Purchaser, in cash, by wire transfer of immediately available funds to an account or accounts designated by such Purchaser via electronic mail at least forty-eight (48) hours in advance, the amount set forth opposite such Purchaser’s name on Schedule I hereto, representing such Purchaser’s Pro Rata Share (as defined below) of the Interest Amount. “Pro Rata Share” means, with respect to each Purchaser, the percentage set forth opposite such Purchaser’s name on Schedule I hereto.

Section 1.02. Exchange Shares. Subject to the terms and conditions hereof, (i) each Purchaser hereby agrees to convert the entire outstanding principal amount of its Notes into the number of Final Conversion Shares set forth opposite such Purchaser’s name on Schedule I hereto in accordance with the terms of the Notes (but without giving effect to the 9.985% Cap (as defined in the Notes)), and (ii) the Borrower hereby agrees to issue to each Purchaser the number of (a) Final Conversion Shares set forth opposite such Purchaser’s name on Schedule I hereto, in satisfaction of the Borrower’s conversion obligation under the Notes and (b) Additional Shares set forth opposite such Purchaser’s name on Schedule I hereto.

Section 1.03. Exchange; Effectiveness; Delivery of Shares. The conversion of the Notes into the Final Conversion Shares and the issuance of the Additional Shares shall be conducted in the manner set forth in this Section 1.03 in lieu of Section 2(c) of the Notes (and without giving effect to the 9.985% Cap). The payment of the Interest Amount and the issuance of the Exchange Shares shall be effectuated by the exchange of the Notes therefor (such payment, issuance and exchange being collectively referred to herein as the “Exchange”). The Exchange shall be deemed effective and consummated immediately upon the execution and delivery of this Agreement by the Parties on the date hereof (the “Effective Time”). No later than one (1) Business Day after the date hereof, the Borrower shall cause the transfer agent for the Common Stock (including any successor thereto, the “Transfer Agent”) to (i) credit the aggregate number of Final Conversion Shares to which each Purchaser is entitled pursuant to the Notes to such Purchaser’s or its designee’s balance account with The Depository Trust Company (“DTC”) through its Deposit/Withdrawal At Custodian (“DWAC”) system per the account information provided by such Purchaser via electronic mail at least forty-eight (48) hours in advance and (ii) to issue and deliver to each Purchaser a certificate representing the aggregate number of Additional Shares to which such Purchaser is entitled pursuant to Section 1.02, which certificate shall bear the Restrictive Legend (as defined below). For the avoidance of doubt, (a) as of the Effective Time, each Purchaser shall be deemed for all corporate purposes to have become the legal and record holder of its Exchange Shares without any further action by any party and, in the case of the Final Conversion Shares, without the need for a separate Conversion Notice (as defined in the Notes) and (b) all of the Exchange Shares shall, for all purposes, be deemed to

have been issued simultaneously as part of a single transaction occurring at the Effective Time, and no Party shall make any assertion to the contrary. In the event that any Exchange Shares are not delivered on a timely basis in accordance herewith, the Purchasers shall have the right to rescind and terminate any or all of this Agreement and the transactions contemplated hereby, to exercise any of the remedies available under the Notes in the event of any failure to timely deliver Conversion Shares (as defined in the Notes), as if the Exchange Shares were Conversion Shares, and/or to exercise any and all other rights and remedies available at law or in equity. The Borrower shall promptly deliver to the Transfer Agent any documentation necessary to effect the issuance of the Final Conversion Shares and the Additional Shares in accordance herewith.

The execution and delivery of this Agreement and the Registration Rights Agreement by the Borrower and the consummation by the Borrower of the transactions contemplated hereby and thereby do not and will not (i) violate any provision of the Borrower’s certificate of incorporation or bylaws, (ii) result in a violation of any law, rule, regulation, order, judgment or decree of any court or governmental authority to which the Borrower is subject, or by which any asset of the Borrower is bound or affected, or (iii) violate, conflict with, result in a breach of, or constitute a default under, or result in the creation or imposition of any Lien (other than Permitted Liens) on any assets of the Borrower pursuant to, any agreement to which the Borrower is a party or by which the Borrower is bound or to which any of the assets of the Borrower is subject, except in the case of clauses (ii) and (iii) above, for any such violation, conflict or breach that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect (it being agreed that for purposes of the definition of “Material Adverse Effect” this Agreement and the Registration Rights Agreement shall constitute “Note Documents”).

(f) Issuance of Shares. The Exchange Shares are duly authorized and, when issued in accordance with this Agreement, will be validly issued, fully paid and nonassessable, free and clear of all Liens imposed by the Borrower, and will not be issued in violation of, or subject to, any preemptive or similar rights of any Person.

COVENANTS

Section 4.01. Legends.

(a) Restrictive Legend. Each Purchaser understands that until such time as the resale of the Additional Shares has been registered under the Securities Act as contemplated by the Registration Rights Agreement or the Additional Shares otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Additional Shares may bear a restrictive legend in substantially the following form (the “Restrictive Legend”):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE

SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION, PURSUANT TO RULE 144 UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

(b) Removal of Restrictive Legends. The certificates evidencing the Additional Shares shall not contain any legend restricting the transfer thereof (including the legend set forth above in Subsection 4.01(a)): (A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering the resale of such Additional Shares by the Purchaser is effective under the Securities Act, or (B) following any sale of such Additional Shares pursuant to Rule 144, or (C) if such Additional Shares are eligible for sale under rule 144(b)(1), or (D) at any time on or after the date hereof that a Purchaser certifies that it is not an “affiliate” (as defined in Rule 144 under the Securities Act) and that such Purchaser’s holding period for purposes of Rule 144 under the Securities Act and subsection (d)(3)(iii) thereof with respect to such Additional Shares is at least six (6) months, or (E) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). Each Purchaser agrees that the removal of the restrictive legend from the Additional Shares in accordance with the immediately preceding sentence is predicated upon the Borrower’s reliance that (i) such Purchaser will dispose of such Additional Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such Additional Shares are sold pursuant to a registration statement, they will be sold in compliance with the plan of distribution set forth therein. Promptly following the Registration Effective Date (as defined below) or such other time as any of the Unrestricted Conditions have been satisfied, the Borrower agrees to effect the removal of the legend thereunder. The Borrower agrees that, following the Registration Effective Date or such other time as any of the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 4.01(b), it will, no later than two (2) Trading Days following the delivery by the Purchaser to the Borrower or the Transfer Agent of any certificate representing Additional Shares, as applicable, issued with a restrictive legend (such second Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Additional Shares to such Purchaser’s or its designee’s balance account with DTC through its DWAC system, free from all restrictive and other legends and stop transfer instructions. For purposes hereof, “Registration Effective Date” shall mean the date that the first Registration Statement that the Borrower is required to file pursuant to the Registration Rights Agreement has been declared effective by the SEC.

Section 4.02. Disclosure; Confidentiality. On or before 9:00 a.m., New York time, on the date hereof (the “8-K Filing Deadline”), the Borrower shall file a Current Report on Form 8-K describing all the material terms of this Agreement and the Registration Rights Agreement and

disclosing any other presently material non-public information (if any) provided or made available to any Purchaser (or any Purchaser’s agents or representatives) on or prior to the date hereof (the “8-K Filing”) and including as an exhibit to the 8-K Filing this Agreement and the Registration Rights Agreement. From and after the 8-K Filing Deadline, the Borrower shall have disclosed all material, non-public information (if any) provided or made available to any Purchaser (or any Purchaser’s agents or representatives) by Borrower or any of its respective officers, directors, employees, Affiliates or agents in connection with the transactions contemplated by this Agreement or otherwise on or prior to the date hereof. Notwithstanding anything contained in this Agreement to the contrary and without implication that the contrary would otherwise be true, after giving effect to the 8-K Filing, the Borrower expressly acknowledges and agrees that no Purchaser shall have (unless expressly agreed to by a particular Purchaser after the date hereof in a written definitive and binding agreement executed by the Borrower and such particular Purchaser or customary oral (confirmed by e-mail) “wall-cross” agreement (it being understood and agreed that no Purchaser may bind any other Purchaser with respect thereto)), any duty of trust or confidence with respect, or a duty not to trade on the basis of, any information regarding the Borrower.

Section 4.03. Taxes. The Borrower shall be responsible for paying all present or future stamp, court or documentary, intangible, recording, filing or similar Taxes that arise from the issuance of Exchange Shares under this Agreement.
