On or before 10:00 a.m., New York City time, on the Business Day prior to the Closing Date, each of the Purchasers will deliver their respective portions of the Purchase Price to the Closing Agent by wire transfer in immediately available funds according to the wire transfer instructions previously delivered to each of such Purchasers.

(i) The Closing Agent may, in its sole discretion, but shall not be obligated to, fund the unfunded portion of the Purchase Price applicable to such Purchaser, on behalf of such Purchaser. The funding of any portion of the Purchase Price by the Closing Agent pursuant to this Section 2.3(d) shall not relieve a defaulting Purchaser of any liability that it may have to the Company or the Closing Agent pursuant to this Agreement or for the breach of its obligations under this Agreement.

(ii) In the event that the Closing Agent shall have funded any such unfunded portion as set forth in the preceding clause (i), the Closing Agent may, in its sole discretion, but shall not be obligated to, (A) retain, at and following the Closing, beneficial ownership in the Securities as such Purchaser would have been entitled to had it timely funded, (B) direct the disposition of such Note to another party or (C) require

such Purchaser, upon written notice, to purchase such Securities from the Closing Agent within two business days after the Closing Date at a price equal to the initial offering price of such Securities plus accrued and unpaid interest to the date of settlement.

(iii) In the case of the preceding clause (ii)(A) or (B), if so requested by the Closing Agent, (A) such Purchaser shall take any action reasonably requested by the Closing Agent to effect the transfer of the applicable Securities to the Closing Agent or such other party, as the case may be, and shall be deemed to have consented to the Closing Agent retaining and taking beneficial ownership, or directing the disposition, of such Securities and (B) the Company shall transfer registration of such Securities to, or as directed by, the Closing Agent.

(e) Distribution of Purchase Price Received by Closing Agent to Escrow Agent. Upon receipt of the Purchase Price from any Purchaser, the Closing Agent will distribute such funds to the Escrow Agent for deposit into the escrow account to be established pursuant to the Closing Escrow Agreement (the “Closing Escrow Account”).

(f) Release of Purchase Price Funds; Delivery of Securities. On the Closing Date:

(i) upon (A) receipt by the Closing Agent of a certificate from the Chief Executive Officer of the Company (the “Company Closing Certificate”) certifying that the conditions to the Purchasers’ obligations to close, as set forth in Section 2.2(a), have been satisfied and (B) the consent of Schulte Roth & Zabel LLP, upon behalf of Highbridge International LLC, that such conditions have been satisfied, the Closing Agent will instruct the Escrow Agent, pursuant to the terms of the Closing Escrow Agreement, to release the Purchase Price as set forth in the Closing Escrow Agreement; and

(ii) in consideration for the receipt of the Purchase Price deposited in the Closing Escrow Account as specified above, the Company shall deliver the Securities to the applicable Purchasers in accordance with the instructions contained in Annex A hereto.

(g) Returning of Funds from the Closing Agent. To the extent the Closing Agent receives any funds from the Escrow Agent for the benefit of any Purchaser pursuant to the Closing Escrow Agreement, whether upon termination of the transactions contemplated hereby, as interest upon funds held in the escrow account or otherwise, the Closing Agent shall wire such funds to the applicable Purchaser, in accordance with instructions provided by such Purchaser(s), within one (1) Business Day of receipt of such funds by the Closing Agent.

either individually or in the aggregate, reasonably be expect to result in a Material Adverse Effect.

In connection with any transfer of the Securities or Conversion Shares, other than pursuant to an effective registration statement, a Rule 144 transfer, to the Company or to an Affiliate of the Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities or Conversion Shares under the Securities Act.

(b) Certificates evidencing the Securities and the Conversion Shares will contain the following legend, so long as is required by this Section 4.2(b) or Section 4.2(c):

[NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON CONVERSION OF THESE SECURITIES HAVE BEEN REGISTERED] [THESE SECURITIES HAVE NOT BEEN REGISTERED] WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.

(c) Following the date that the Securities and the Conversion Shares are registered for resale under the Securities Act or, subject to receipt of appropriate representations from the Purchaser and, if applicable its broker, at such earlier time as a legend is no longer required for the Securities and the Conversion Shares under this Section 4.2(c), the Company will, no later than three Trading Days following the delivery by the Purchaser to the Company or the Company’s transfer agent of a certificate representing Securities or Conversion Shares containing a restrictive legend, together with a request to issue a certificate without a restrictive legend, deliver or cause to be delivered to the Purchaser a certificate representing such Securities or Conversion Shares that is free from all restrictive and other legends or, at the Company’s

option upon the holder’s request, issue such Securities or Conversion Shares to the nominee of The Depository Trust Company with instructions to credit the account of the participant designated by the holder. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section except as it may reasonably determine are necessary or appropriate to comply or to ensure compliance with those applicable laws that are enacted or modified after the Closing.

The Company shall make all filings and reports relating to the offer and sale of the Securities by the Company and to the resale of the Securities and the Conversion Shares by the Purchaser required under applicable securities or “Blue Sky” laws of the states of the United States promptly following the Closing Date.

4.4 Furnishing of Information; Information Rights. As long as the Purchaser owns any of the Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act and to disclose in the Registration Statement any material, nonpublic information provided to the Purchaser except to the extent previously disclosed or the Company determines that such information is no longer material, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would otherwise permit such termination except in connection with a Fundamental Transaction (as defined in the Indenture). In furtherance of the foregoing, the Company shall make available to the Purchaser or file with the Commission via the EDGAR system: (a) as soon as practicable, but in any event within ninety (90) days after the end of each fiscal year of the Company, (i) a balance sheet as of the end of such year; (ii) statements of income and of cash flows for such year; and (iii) a statement of stockholders’ equity as of the end of such year, audited and certified by independent registered public accounting firm selected by the Company, (b) as soon as practicable, but in any event within forty-five (45) days after the end of each of the first three (3) quarters of each fiscal year of the Company, unaudited statements of income and of cash flows for such fiscal quarter, and an unaudited balance sheet as of the end of such fiscal quarter, all prepared in accordance with GAAP (except that the financial statements may (i) be subject to normal year-end audit adjustments and (ii) not contain all notes thereto that may be required in accordance with GAAP), (c) unless available to the public through the EDGAR system, within one (1) Business Day of the filing thereof with the Commission, unless the following are filed with the Commission through EDGAR and are available to the public through the EDGAR system, a copy of its Annual Reports and Quarterly Reports on Form 10-K, 10-KSB, 10-Q or 10-QSB, any interim reports or any consolidated balance sheets, income statements, stockholders’ equity statements and/or cash flow statements for any period other than annual, any Current Reports on Form 8-K and any registration statements (other than on Form S-8) or amendments filed

pursuant to the Securities Act and (d) copies of any notices and other information made available or given to the stockholders of the Company generally, contemporaneously with the making available or giving thereof to the stockholders .

4.5 Pledge of Securities. The Company acknowledges and agrees that the Securities may be pledged by a Holder (as defined in the Registration Rights Agreement) in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Investor effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document, including, without limitation, Section 3.2(k) hereof; provided that an Investor and its pledgee shall be required to comply with the provisions of Section 3.2(k) hereof in order to effect a sale, transfer or assignment of Securities to such pledgee. The Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by an Investor.

4.6 Integration. The Company shall not, and shall use its best efforts to ensure that no Subsidiary or Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchaser, or that will be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market.

From and after the filing of the 8-K Filing with the Commission, the Purchaser, as a consequence of participating in the transactions contemplated by this Agreement or pursuant to due diligence in connection therewith, shall not be in possession of any material, nonpublic information received from the Company, any of its Subsidiaries or any of their respective officers, directors, employees or agents, that is not disclosed in the 8-K Filing unless the Purchaser has executed a non-disclosure agreement

relating to such information. The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective officers, directors, employees and agents, not to, provide the Purchaser with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the filing of the 8-K Filing with the Commission without the consent of the Purchaser. If the Purchaser has, or believes it has, received any such material, nonpublic information regarding the Company or any of its Subsidiaries from the Company, any of its Subsidiaries or any of their officers, directors, employees or agents prior to the Closing Date, it shall provide the Company with written notice thereof and the Company shall within two (2) Trading Days thereafter, make public disclosure of such material, nonpublic information if permitted under applicable law or without breach or violation of any agreement, contract or other obligation of the Company; provided, that if the Company shall fail to make such public disclosure within such two (2) Trading Day period, the Purchaser shall be entitled to make public disclosure of such information to the extent permitted under applicable law or without breach or violation of any agreement, contract or other obligation of the Company.

Each of the Company and the Purchaser agrees and acknowledges that the Placement Agent and the Closing Agent may rely on the representations, warranties, covenants and agreements of each of the Company and the Purchaser, as applicable, contained in this Agreement as if such representations, warranties, covenants and agreements, as applicable, were made directly to the Placement Agent and the Closing Agent.

4.11 Limitation on Duties of Closing Agent and Placement Agents; Exculpation.

For so long as any Securities remain outstanding, the Company shall not, in any manner, issue or sell any rights, warrants or options to subscribe for or purchase Common Stock or directly or indirectly convertible into or exchangeable or exercisable for Common Stock at a price which varies or may vary with the market price of the Common Stock, including by way of one or more reset(s) to any fixed price unless the conversion, exchange or exercise price of any such security cannot be less than the closing bid price of the Common Stock on the date of issuance of any such security. For so long as any Securities remain outstanding, the Company shall not, in any manner, enter into or affect any dilutive issuances if the effect of such dilutive issuance is to cause the Company to be required to issue upon conversion of any Security any shares of Common Stock in excess of that number of shares of Common Stock which the Company may issue upon conversion of the Securities without breaching the Company’s obligations under the rules or regulations of the Trading Market.

4.14 Additional Issuances of Securities.

(b) From the date hereof until the date that is sixty-one (61) Trading Days following the Effective Date (as defined in the Registration Rights Agreement) (the “Trigger Date”), the Company will not, directly or indirectly, file any registration statement with the Commission other than the Registration Statement (as defined in the Registration Rights Agreement) and the registration statement contemplated in the Share Loan Registration Rights Agreement among the Company, the lenders named therein and Jefferies & Company, Inc. From the date hereof until the Trigger Date, the Company will not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of) any of its or its Subsidiaries’ equity or equity equivalent securities solely for cash, including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for shares of Common Stock or Common Stock Equivalents (any such offer, sale, grant, disposition or announcement being referred to as a “Subsequent Placement”).

(c) From the Trigger Date until the later of (i) third anniversary of the Closing Date and (ii) the date no Securities remain outstanding, the Company will not, directly

or indirectly, effect any Subsequent Placement unless the Company shall have first complied with this Section 4.14(c).

(i) The Company shall deliver to each Purchaser an irrevocable prior written notice of five (5) Business Days (the ”Offer Notice”) of any proposed or intended issuance or sale or exchange (the ”Offer”) of the securities being offered (the “Offered Securities”) in a Subsequent Placement, subject to such Purchaser’s prior agreement to maintain the confidentiality of such Offer Notice, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price (which may be expressed as a formula) and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the persons or entities (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged (unless the Company or the placement agent is prohibited from doing so by contract or by law) and (z) offer to issue and sell to or exchange with the Purchaser up to fifty percent (50%) of the Offered Securities, allocated among the Purchaser and the other Purchasers (a) based on such Purchaser’s pro rata portion of the aggregate principal amount of Securities purchased hereunder (the “Basic Amount”), and (b) with respect to each Purchaser that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Purchasers as the Purchaser shall indicate it will purchase or acquire should the other Purchasers subscribe for less than their Basic Amounts (the “Undersubscription Amount”), which process shall be repeated until the Purchaser shall have an opportunity to subscribe for any remaining Undersubscription Amount; provided, that the time period for any Purchaser to elect to purchase any Undersubscription Amount shall be one (1) Business Day; provided, further, that the total time period for electing to participate in the Offer, including in connection with any Undersubscription Amount, shall be no longer than seven (7) Business Days.

(ii) To accept an Offer, in whole or in part, the Purchaser must deliver a written notice to the Company prior to the end of the fifth (5th) Business Day after the Purchaser’s receipt of the Offer Notice (the “Offer Period”), setting forth the portion of the Purchaser’s Basic Amount that the Purchaser elects to purchase and, if the Purchaser shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that the Purchaser elects to purchase (in either case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by the Purchaser and the other Purchasers are less than the total of all of the Basic Amounts, then each Purchaser who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), each Purchaser who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of the Purchaser bears to the total Basic Amounts of the Purchaser and the other Purchasers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent its deems reasonably necessary.

(iii) The Company shall have twenty-five (25) calendar days from the expiration of the Offer Period above to offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Purchaser (the “Refused Securities”), but only to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less favorable to the Company than those set forth in the Offer Notice and (ii) to publicly announce (a) the execution of such Subsequent Placement Agreement, and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the Commission on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein filed as exhibits thereto.

(iv) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 4.14(c)(iii) above), then each Purchaser may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that the Purchaser elected to purchase pursuant to Section 4.14(c)(ii) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to the Purchaser pursuant to Section 4.14(c)(iii) above prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Purchaser so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Purchaser in accordance with Section 4.14(c)(i) above.

(v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Purchaser shall acquire from the Company, and the Company shall issue to the Purchaser, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 4.14(c)(iv) above if the Purchaser has so elected, upon the terms and conditions specified in the Offer. The purchase by the Purchaser of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Purchaser of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Purchaser and their respective counsel.

(vi) Any Offered Securities not acquired by the Purchaser or other persons in accordance with Section 4.14(c)(iii) above may not be issued, sold or exchanged until they are again offered to the Purchaser under the procedures specified in this Agreement.

(vii) The Company and the Purchaser agree that if any Purchaser elects to participate in the Offer, (x) neither the Subsequent Placement Agreement with

respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement Documents”) shall include any term or provisions whereby any Purchaser shall be required to agree to any restrictions in trading as to any securities of the Company owned by the Purchaser prior to such Subsequent Placement, and (y) any registration rights set forth in such Subsequent Placement Documents shall be similar in all material respects to the registration rights contained in the Registration Rights Agreement.

(viii) Notwithstanding anything to the contrary in this Section 4.14 and unless otherwise agreed to by the Purchaser, the Company shall either confirm in writing to the Purchaser that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case in such a manner such that the Purchaser will not be in possession of material non-public information, by the thirty-fifth (35th) calendar day following delivery of the Offer Notice. If by the thirty-fifth (35th) calendar day following delivery of the Offer Notice no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction has been received by the Purchaser, such transaction shall be deemed to have been abandoned and the Purchaser shall not be deemed to be in possession of any material, non-public information with respect to the Company. Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide each Purchaser with another Offer Notice and each Purchaser will again have the right of participation set forth in this Section 4.14(c).

(d) The restrictions contained in subsections (b) and (c) of this Section 4.14 shall not apply in connection with the issuance of any Excluded Securities (as defined in the Indenture) or in connection with any Common Shares issued or issuable pursuant to a bona fide firm commitment underwritten public offering with a nationally recognized underwriter which generates gross proceeds to the Company in excess of $20,000,000 (other than an “at-the-market offering” as defined in Rule 415(a)(4) under the Securities Act and an “equity line”).

4.15 Incorporation by Reference of Indenture Provision. Each of Sections 4.04(a) and 4.04(e) of the Indenture are hereby incorporated by reference in this Agreement as if such provisions were included herein; provided, that all references to Holder or Holders shall instead refer to Purchaser or Purchasers, respectively.

The decision of the

Purchaser to purchase Securities pursuant to the Transaction Documents has been made by the Purchaser independently of, and without reliance on, the other Purchasers or any other Purchasers’ legal counsel or financial advisors. Nothing contained herein or in any Transaction Document, and no action taken by the Purchaser pursuant thereto, shall be deemed to constitute the Purchaser, together with the other Purchasers, as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that such parties are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Purchaser acknowledges that none of the other Purchasers has acted as agent for the Purchaser in connection with making its investment hereunder and that none of the other Purchasers will be acting as agent of the Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. The Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any of the other Purchasers to be joined as an additional party in any proceeding for such purpose.

Nothing in this Section 5.14 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. Except as set forth in the immediately preceding sentence, upon a termination in accordance with this section, the Company and the Purchaser shall not have any further obligation or liability (including arising from such termination) to the other.
