(a) “THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER ANY STATE SECURITIES LAWS, IN RELIANCE UPON EXEMPTIONS FROM REGISTRATION FOR NON-PUBLIC OFFERINGS. THIS SECURITY MAY NOT BE SOLD OR TRANSFERRED UNLESS IT IS REGISTERED UNDER THE ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR UNLESS THERE IS AN AVAILABLE EXEMPTION FROM, OR SUCH SALE OR TRANSFER IS IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, AS EVIDENCED BY AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER.”

(b) If required by the authorities of any state in connection with the issuance of sale of the Securities, the legend required by such state authority.

Upon registration for resale pursuant to the Registration Rights Agreement, and for so long as (and at all times as) such Registration Statement remains effective, or upon Rule 144(k) under the 1933 Act becoming available, the Company shall promptly cause certificates evidencing the Underlying Shares and Warrant Shares previously issued to be replaced with certificates which do not bear such restrictive legends, and all Underlying Shares and Warrant Shares subsequently issued shall not bear such restrictive legends.

The parties acknowledge and agree that on or prior to the Closing, the Registration Rights Agreement will be duly executed and delivered by the parties thereto.

7. Covenants and Agreements of the Company.

7.1. 19.9% Cap; Rule 144.

(a) 19.9% Cap. In the event that at any time the Company would be obligated to issue an amount of shares upon conversion of, as payment for dividends on, for redemption of, and otherwise pursuant to, the Preferred Shares, or upon exercise of the Warrants, which, when aggregated with all shares of Common Stock issued to the Purchasers hereunder (including under the Certificate and Warrants and including to other purchasers of Preferred Shares), would constitute a breach of the Company’s obligations under the rules or regulations of the American Stock Exchange as they apply to the Company, or any other principal securities exchange or market (“Principal Market”) upon which the Common Stock is or becomes traded (the “Cap Regulations”), the Company shall not be obligated to issue any such shares of Common Stock to the extent such shares are in excess of the maximum permissible amount (“Maximum Common Stock Issuance”) under such Cap Regulations (“Excess Shares”). Each holder of Preferred Shares shall be entitled to receive the number of Underlying Shares, together with its Warrant Shares under the Warrant held by it, equal to such holder’s pro rata share of the Maximum Common Stock Issuance (based upon its aggregate Purchase Price under the Purchase Agreement). Once a holder has received its total pro rata share upon conversion of its Preferred Shares and exercise of its Warrants, and if the Company shall not have complied with its obligations to obtain the stockholder approval described below by the date set forth below, it shall have the right to compel the Company to redeem its remaining Preferred Shares and Warrants as set forth below. If a holder has converted and exercised all of its Preferred Shares and Warrants, but has not depleted the total number of pro rata shares of the Maximum Common Stock Issuance allocated to it hereunder, its remaining pro rata shares shall be reallocated amongst the other holders still holding Preferred Shares and Warrants on a pro rata basis. If at any point in time and from time to time (each a “Trigger Date”) the number of shares of Common Stock issued pursuant to conversion of the Preferred Shares and exercise of the Warrants, together with the number of shares of Common Stock that would then be issuable by the Company upon conversion of all the Preferred Shares and exercise of all the Warrants then outstanding, would exceed the Maximum Common Stock Issuance but for this Section, then the Company shall, at the Company’s election, either (A) promptly call a shareholders meeting to obtain shareholder approval for the issuance of shares of Common Stock hereunder in excess of the Maximum Common Stock Issuance, which such shareholder approval shall be obtained within 60 days following the Trigger Date, or (B) purchase from the holders of Preferred Shares and Warrants on a pro rata basis

such number of Preferred Shares and number of Warrants which cannot be converted or exercised due to such Maximum Common Stock Issuance limitation at a redemption price equal to (x) for the Preferred Shares, 100% of such Liquidation Value (as defined in the Certificate), and (y) for the Warrants, the number of Excess Shares underlying the Warrant multiplied by the positive difference, if any, of the closing sale price on the American Stock Exchange as of the Trigger Date minus the Warrant Price (as defined in the Warrants). Such redemption price shall be paid within five (5) trading days after a Trigger Date if this clause (B) is elected. The Company shall make such election with three (3) days following the Trigger Date by giving written notice to all holders of Preferred Shares and Warrants. If the Company fails to timely make such election, or elects clause (A) but then fails to obtain such shareholder approval within 60 days following the Trigger Date, then the Company shall purchase such Preferred Shares and Warrants which cannot be converted or exercised within five (5) trading days following any such failure. Only shares of Common Stock acquired pursuant to this Agreement (including Underlying Shares and Warrant Shares) will be included in determining whether the limitation contained herein would be exceeded for purposes of this Section 7.1(a).

(b) Rule 144. The Company agrees that, for purposes of determining the holding period under Rule 144 of the 1933 Act for Underlying Shares issued upon conversion of the Preferred Shares, the holding period of such Underlying Shares shall be tacked to the holding period of the Preferred Shares. The Company agrees to make publicly available on a timely basis the information necessary to enable Rule 144 under the 1933 Act to be available for resale.

7.2. [Intentionally omitted]

7.3. Right of the Purchasers to Participate in Future Transactions. For the two-year period commencing on the Closing Date, The Tail Wind Fund Ltd. and Solomon Strategic Holdings, Inc. will have a right to participate in any sales of any of the Company’s securities in a capital raising transaction on the terms and conditions set forth in this Section 7.3. During such period, the Company shall give 36 hours advance written notice to such Purchasers prior to any non-public offer or sale of any of the Company’s equity securities or any securities convertible into or exchangeable or exercisable for such securities in a capital raising transaction by providing to such Purchasers a comprehensive term sheet containing all significant business terms of such a proposed transaction. Such Purchasers shall have the right (pro rata in accordance with such Purchasers’ purchase price for the Preferred Shares) to participate in such transaction by purchasing in such transaction an amount of the identical securities issued in such transaction equal to up to 15% of the aggregate amount of such securities issued to such Purchasers and such other investors together for the same consideration and on the same terms and conditions as such third-party sale. If, subsequent to the Company giving notice to such Purchasers hereunder but prior to each of such Purchasers exercising its rights hereunder, the terms and conditions of the third-party sale are changed from that disclosed in the

comprehensive term sheet provided to such Purchaser, the Company shall be required to provide a new notice to such Purchaser hereunder and such Purchasers shall have the right to exercise their rights to purchase the identical securities in such transaction on such changed terms and conditions as provided hereunder. The rights and obligations of this Section 7.3 shall in no way diminish the other rights of the Purchasers pursuant to this Section 7. Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by any Purchaser pursuant to any capital raising transaction as described in this Section 7.3 shall not exceed a number that, when added to the total number of shares of Common Stock deemed beneficially owned by such Purchaser (other than by virtue of the ownership of securities or rights to acquire securities that have limitations on the Purchaser’s right to convert, exercise or purchase similar to the limitation set forth herein), together with all shares of Common Stock deemed beneficially owned by the Purchaser’s “affiliates” (as defined in Rule 144 of the 0000 Xxx) that would be aggregated for purposes of determining whether a group under Section 13(d) of the 1934 Act, exists, would exceed 9.9% of the total issued and outstanding shares of the Common Stock.

7.4. Opinion of Counsel. On or prior to the Closing Date, the Company will deliver to the Purchasers the opinions of legal counsel to the Company substantially in the form and substance attached hereto as Exhibit D.

7.5. Reservation of Common Stock issuable upon Conversion of Preferred Shares and Exercise of Warrants. The Company hereby agrees at all times to reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of providing for the full conversion of Preferred Shares (including payment of accrued dividends thereon and redemption thereof) and the exercise of the Warrants, such number of shares of Common Stock as shall from time to time equal the number of shares sufficient to permit the full conversion of Preferred Shares (including payment of accrued dividends thereon and redemption thereof) in accordance with the terms of the Certificate and to permit the full exercise of the Warrants in accordance with the terms of the Warrants. All calculations pursuant to this paragraph shall be made without regard to restrictions on beneficial ownership.

7.6. Reports. For so long as the Purchasers beneficially own the Preferred Shares or Warrants, the Company will furnish to the Purchasers the following reports, each of which shall be provided to the Purchasers by air mail or reputable international courier (within one week of filing with the SEC, in the case of SEC filings), to the extent not filed on and available at that time via XXXXX:

(a) Quarterly Reports. As soon as available and in any event within 45 days after the end of each fiscal quarter of the Company, the Company’s quarterly report on Form 10-Q or, in the absence of such report, consolidated balance sheets of the Company as at the end of such period and the related consolidated statements of operations, stockholders’

equity and cash flows for such period and for the portion of the Company’s fiscal year ended on the last day of such quarter, all in reasonable detail and certified by the Company to have been prepared in accordance with generally accepted accounting principles, subject to year-end and audit adjustments.

(b) Annual Reports. As soon as available and in any event within 90 days after the end of each fiscal year of the Company, the Company’s Form 10-K or, in the absence of a Form 10-K, consolidated balance sheets of the Company as at the end of such fiscal year and the related consolidated statements of earnings, stockholders’ equity and cash flows for such year, all in reasonable detail and accompanied by the report on such consolidated financial statements of an independent certified public accountant selected by the Company and reasonably satisfactory to the Purchaser.

(c) Securities Filings. As promptly as practicable and in any event within five days after the same are issued or filed, copies of (i) all notices, proxy statements, financial statements, reports and documents as the Company shall send or make available generally to its stockholders or to financial analysts, and (ii) all periodic and special reports, documents and registration statements (other than on Form S-8) which the Company furnishes or files, or, to the extent also delivered to the Company, any officer or director of the Company (in such person’s capacity as such) furnishes or files with the SEC.

(d) Other Information. Such other information relating to the Company as from time to time may reasonably be requested by any Purchaser provided the Company produces such information in its ordinary course of business, and further provided that the Company, solely in its own discretion, determines that such information is not confidential in nature and disclosure to the Purchaser would not be harmful to the Company or violate any rules or regulations of the SEC or the American Stock Exchange.

7.7. Press Releases. Any press release or other publicity concerning this Agreement or the transactions contemplated by this Agreement shall be submitted to the Purchasers for comment at least two (2) business days prior to issuance, unless the release is required to be issued within a shorter period of time by law or pursuant to the rules of the American Stock Exchange or another national securities exchange or market. The Company shall issue a press release concerning the fact and material terms of this Agreement within three business days of the Closing, provided that in lieu thereof the

Company may file a Form 8-K concerning the fact and material terms of this Agreement within five business days of the Closing (attaching such Agreements as applicable).

7.8. No Conflicting Agreements. The Company will not take any action, enter into any agreement or make any commitment that would conflict or interfere in any material respect with the obligations to the Purchasers under the Agreements.

7.9. Insurance. For so long as any Purchaser beneficially owns any of the Securities, the Company shall have in full force and effect (a) insurance reasonably believed by the Company to be adequate on all assets and activities, covering property damage and loss of income by fire or other casualty, and (b) insurance reasonably believed to be adequate protection against all liabilities, claims and risks against which it is customary for companies similarly situated as the Company to insure.

7.10. Compliance with Laws. So long as the Purchasers beneficially own any Securities, the Company will use reasonable efforts to comply with all applicable laws, rules, regulations, orders and decrees of all governmental authorities, except to the extent non-compliance (in one instance or in the aggregate) would not have a Material Adverse Effect.

7.11. Listing of Underlying Shares and Related Matters. The Company hereby agrees, promptly following the Closing of the transactions contemplated by this Agreement, to take such action to cause the Underlying Shares and the Warrant Shares to be listed on the American Stock Exchange as promptly as possible but no later than the effective date of the registration contemplated by the Registration Rights Agreement. The Company further agrees that if the Company applies to have its Common Stock or other securities traded on any other principal stock exchange or market, it will include in such application the Underlying Shares and Warrant Shares and will take such other action as is necessary to cause such Common Stock to be so listed. For so long as any Preferred Shares remain outstanding, the Company will take all action necessary to continue the listing and trading of its Common Stock on the AMEX or another Approved Market, and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of such exchange or market, as applicable, to ensure the continued eligibility for trading of the Underlying Shares and the Warrant Shares thereon.

7.12. Corporate Existence. So long as any Preferred Shares or Warrants remain outstanding, the Company shall maintain its corporate existence, except in the event of a merger, consolidation or sale of all or substantially all of the Company’s assets so long as the surviving or successor entity in such transaction (a) assumes the Company’s obligations hereunder and under the agreements and instruments entered into in connection herewith, regardless of whether or not the Company would have had a sufficient number of shares of Common Stock authorized and available for issuance in order to fulfill its obligations hereunder and effect the conversion (including payment on)

and exercise in full of all Preferred Shares and Warrants outstanding as of the date of such transaction; (b) has no legal, contractual or other restrictions on its ability to perform the obligations of the Company hereunder and under the agreements and instruments entered into in connection herewith; and (c)(i) is a publicly traded corporation whose common stock and the shares of capital stock issuable upon conversion and exercise of the Preferred Shares and Warrants are (or would be upon issuance thereof) listed for trading on an Approved Market or (ii) if not such a publicly traded corporation, then the buyer agrees that it will, at the election of the Purchasers, purchase such Purchasers’ Securities at a price equal to the greater of (a) 120% of the Purchase Price of such Securities or (b) the fair market value of such Securities on an as-converted and as-exercised basis based on the closing price immediately preceding such transaction or the redemption date, whichever is greater.

8. Survival. All representations, warranties, covenants and agreements contained in this Agreement shall be deemed to be representations, warranties, covenants and agreements as of the date hereof and shall survive the execution and delivery of this Agreement and terminate upon expiration of the applicable statute of limitations.

9. Miscellaneous.

This Agreement may not be assigned by any Purchaser without the prior written consent of the Company, which consent may not be unreasonably withheld or delayed, except that without the prior written consent of the Company, but after notice duly given, a Purchaser may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to any Person to which such Purchaser has transferred or assigned all or part of its Preferred Shares or Warrants in accordance with the terms of the Certificate and Warrants, provided in each case that such Affiliate, transferee or assignee acknowledges in writing to the Company that the representations and warranties contained in Section 5 hereof shall apply to such Affiliate, transferee or assignee. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties.

The Company shall pay all fees and expenses of any placement agents or finders in connection with the transactions contemplated by this Agreement pursuant to a separate agreement between such parties.

9.6. Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and holders of 75% of the Preferred Shares, provided, however, that any such amendment or waiver effected in accordance with this paragraph shall be binding upon each holder of any Securities purchased under this Agreement at the time outstanding, each future holder of all such securities, and the Company.

9.9. Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

9.10. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws.

9.11. Remedies.

(a) The Purchasers shall be entitled to specific performance of the Company’s obligations under the Agreements.

(b) The Company on the one hand, and each Purchaser severally and not jointly on the other hand, shall indemnify the other and hold it harmless from any loss, cost, expense or fees (including attorneys’ fees and expenses) arising out of any breach of any representation, warranty, covenant or agreement in any of the Agreements, or arising out of the enforcement of this Section 9.11.

9.12. Jurisdiction. The parties hereby agree that all actions or proceedings arising directly or indirectly from or in connection with this Agreement or the other Agreements shall be litigated only in the Supreme Court of the State of New York or the United States District Court for the Southern District of New York located in New York County, New York. The parties consent to the jurisdiction and venue of the foregoing courts and consent that any process or notice of motion or other application to either of said courts or a judge thereof may be served inside or outside the State of New York or the Southern District of New York by registered mail, return receipt requested, directed to the party being served at its address set forth in this Agreement (and service so made shall be deemed complete three (3) days after the same has been posted as aforesaid) or by personal service or in such other manner as may be permissible under the rules of said courts. The Company and the Purchasers hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement or the other Agreements.

9.13. Like Treatment of Purchasers and Holders. Neither the Company nor any of its affiliates shall, directly or indirectly, pay or cause to be paid any consideration (immediate or contingent), whether by way of interest, fee, payment for the redemption, conversion or exercise of the Securities, or otherwise, to any Purchaser or holder of Securities, for or as an inducement to, or in connection with the solicitation of, any consent, waiver or amendment of any terms or provisions of the Agreements, unless such consideration is required to be paid to all Purchasers or holders of Securities bound by such consent, waiver or amendment. The Company shall not, directly or indirectly, redeem any Securities unless such offer of redemption is made pro rata to all Purchasers and holders of Securities on identical terms. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.

9.14. Actions of Purchasers. The obligations of each Purchaser hereunder and under the documents contemplated hereby are several and not joint with the obligations of any other Purchaser, and no Purchaser shall in any way be responsible for the performance of the obligations of any other Purchaser under any such document. Nothing contained herein or in any other document contemplated hereby, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute any of 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 hereby or thereby. Each Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other document contemplated hereby, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Notwithstanding anything herein to the contrary, the actions and obligations of the Purchasers hereunder shall at all times be considered several and not joint, and the Purchasers are not, under any circumstances, agreeing to act jointly with respect to the Securities or any of their actions or obligations under the Agreements, and shall not constitute a “group” under the 1934 Act. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no other Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment hereunder. Each 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 Agreements, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. The Company has elected to provide all Purchasers with the same terms and Agreements for the convenience of the Company and not because it was required or requested to do so by the Purchasers.
