(a) Initial Purchase; Commencement of Regular Purchases of Common Stock. Within one (1) Business Day following the satisfaction of the conditions (the “Commencement”) as set forth in Sections 7 and 8 below (the date of satisfaction of such conditions, the “Commencement Date”), the Investor shall purchase from the Company 350,000 Purchase Shares (such purchase the “Initial Purchase” and such Purchase Shares are referred to herein as “Initial Purchase Shares”) and warrants to purchase 350,000 shares of Common Stock (the “Warrants” and the shares of Common Stock underlying such Warrants, the “Warrant Shares”) in the form of Exhibit F attached hereto, and upon receipt of such Purchase Shares and Warrants pay to the Company as the purchase price for such Initial Purchase Shares and Warrants, the sum of $375,000, via wire transfer. The Warrants shall have a term of five (5) years and an exercise price equal to $1.20.

Thereafter, upon notice from the Company and subject to the Company’s right to adjust purchases under Section 2(c) hereof, the Investor shall purchase 20,000 Purchase Shares every five (5) Business Days (such purchases “Regular Purchases” and the amount so purchased the “Regular Purchase Amount”) during each Monthly Period until the Maturity Date, at the Purchase Price.

(b) Accelerated Purchases. In addition to the Regular Purchases, the Company shall have the right at any time on or after the Commencement Date to direct the Investor to purchase up to 10,000 Purchase Shares (such purchases “Accelerated Purchases” and the amount so purchased “Accelerated Purchase Amount”) at the Purchase Price on the Purchase Date, by delivery to the Investor of an Accelerated Purchase Notice which notice shall state the Accelerated Purchase Amount. The Company may direct the Investor to make multiple Accelerated Purchases so long as at least two (2) Business Days have passed since the most recent Accelerated Purchase was completed.

(c) The Company’s Right to Adjust Purchases. The Company may, at any time, give written notice (a “Purchase Adjustment Notice”) to the Investor (i) suspending purchases of Purchase Shares by the Investor under this Agreement, or (ii) adjusting the Regular Purchase Amount to an amount equal to or between 5,000 and 20,000 Purchase Shares as set forth in the Purchase Adjustment Notice. The Purchase Adjustment Notice shall be effective only for purchases that have a Purchase Date later than five (5) Business Days after receipt of the Purchase Adjustment Notice by the Investor. Any purchase by the Investor that has a Purchase Date on or prior to the fifth (5th) Business Day after receipt by the Investor of a Purchase Adjustment Notice from the Company must be honored by the Company as otherwise provided herein. Such purchase adjustment shall continue in effect until delivery by the Company, at its sole discretion, of a new Purchase Adjustment Notice. So long as a Purchase Adjustment Notice suspends purchases, the Investor shall not be obligated or have the right to purchase any Purchase Shares from the Company under Section 2 of this Agreement.

(d) Payment for Purchase Shares. The Investor shall pay to the Company an amount equal to the Purchase Amount multiplied by the Purchase Price with respect to such Purchase Shares as full payment for such Purchase Shares via wire transfer of immediately available funds on the same Business Day that the Investor receives such Purchase Shares if they are received by the Investor before 11:00 a.m. eastern time or if received by the Investor after 11:00 a.m. eastern time, the next Business Day. The Company shall not issue any fraction of a share of Common Stock upon any purchase.

All payments made under this Agreement shall be made in lawful money of the United States of America or wire transfer of immediately available funds to such account as the Company may from time to time designate by written notice in accordance with the provisions of this Agreement. Whenever any amount expressed to be due by the terms of this Agreement is due on any day that is not a Business Day, the same shall instead be due on the next succeeding day that is a Business Day. The parties may otherwise agree on the purchase and sale of Purchase Shares.

(e) Purchase Price Floor. The Company and the Investor shall not effect any sales and purchases under this Agreement on any Purchase Date where the Purchase Price for any purchases of Purchase Shares would be less than the Floor Price. “Floor Price” means $1.00, which shall be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split or other similar transaction.

(f) Records of Purchases. The Investor and the Company shall each maintain records showing the remaining Available Amount at any given time and the dates and Purchase Amounts for each purchase or shall use such other method, reasonably satisfactory to the Investor and the Company.

(g) Taxes. The Company shall pay any and all transfer, stamp or similar taxes that may be payable with respect to the issuance and delivery of any shares of Common Stock to the Investor made under this Agreement.

(h) Additional Purchases. In conjunction with each Regular Purchase and each Accelerated Purchase, if any, the Investor shall purchase up to an equivalent amount of shares of Common Stock as it purchases in connection with each Regular Purchase as such amount may be adjusted by the Company pursuant to a Purchase Adjustment Notice or Accelerated Purchase (“Additional Purchase”). The Additional Purchase shall be at the same purchase price as such Regular or Accelerated Purchase and shall be completed within five (5) Business Days of any Regular Purchase or Accelerated Purchase.

(i) Compliance with Principal Market Rules; Company Rights Agreement. The Company shall not effect any sale under this Agreement and the Investor shall not have the right or the obligation to purchase shares of Common Stock under this Agreement to the extent that after giving effect to such purchase the “Exchange Cap” shall be deemed to be reached. The “Exchange Cap” shall be deemed to have been reached if, at any time prior to the shareholders of the Company approving the transaction contemplated by this Agreement, upon a purchase under this Agreement, the Purchase Shares issuable pursuant to such purchase would, together with all Purchase Shares previously issued under this Agreement, exceed 4,247,936 shares of Common Stock (19.99% of the 21,250,304 outstanding shares of Common Stock as of the date of this Agreement). The Company may, but shall be under no obligation to, request its shareholders to approve the transaction contemplated by this Agreement. The Company shall not be required to issue any Purchase Shares under this Agreement if such issuance would breach the Company’s obligations under the rules or regulations of the Principal Market.

The Company shall not effect any sale under this Agreement and the Investor shall not have the right or the obligation to purchase shares of Common Stock under this Agreement to the extent that after giving effect to such purchase the “Rights Agreement Cap” shall be deemed to be reached. The “Rights Agreement Cap” shall be deemed to have been reached if, at any time prior to the Board of Directors of the Company modifying the Rights Agreement dated as of October 25, 2006 between the Company and Mellon Investor Services LLC, as Rights Agent, as amended, to preclude the triggering of rights under the Rights Agreement, upon a purchase under this Agreement, the Purchase Shares issuable pursuant to such purchase would, together with all Purchase Shares previously issued under this Agreement and not sold by the Investor, exceed 3,185,421 shares of Common Stock (14.99% of the 21,250,304 outstanding shares of Common Stock as of the purchase date. The Investor shall notify the Company in writing prior to any purchase of shares of Common Stock under this Agreement to the extent that after giving effect to such purchase the Rights Agreement Cap shall be deemed to be reached, based upon the number of outstanding shares of Common Stock reported in the Company’s most recent Report on Form 10-Q or 10-K.

(l) Termination. This Agreement may be terminated only as follows:

(i) By the Investor any time an Event of Default exists without any liability or payment to the Company. However, if pursuant to or within the meaning of any Bankruptcy Law, the Company commences a voluntary case or any Person commences a proceeding against the Company, a Custodian is appointed for the Company or for all or substantially all of its property, or the Company makes a general assignment for the benefit of its creditors, (any of which would be an Event of Default as described in Sections 10(f), 10(g) and 10(h) hereof) this Agreement shall automatically terminate without any liability or payment to the Company without further action or notice by any Person. No such termination of this Agreement under this Section 11(k)(i) shall affect the Company’s or the Investor’s obligations under this Agreement with respect to pending purchases or Additional Purchases and the Company and the Investor shall complete their respective obligations with respect to any pending purchases or Additional Purchases under this Agreement.

(iii) In the event that the Commencement shall not have occurred on or before May 31, 2010, due to the failure to satisfy the conditions set forth in Sections 7 and 8 above with respect to the Commencement, the non-breaching party shall have the option to terminate this Agreement at the close of business on such date or thereafter without liability of any party to any other party.

(iv) At any time after the Commencement Date, the Company shall have the option to terminate this Agreement for any reason or for no reason by delivering notice (a “Company Termination Notice”) to the Investor electing to terminate this Agreement without any liability whatsoever of any party to any other party under this Agreement. The Company Termination Notice shall not be effective until one (1) Business Day after it has been received by the Investor. No such termination of this Agreement under this Section 11(k)(iv) shall affect the Company’s or the Investor’s obligations under this Agreement with respect to pending purchases or Additional Purchases and the Company and the Investor shall complete their respective obligations with respect to any pending purchases or Additional Purchases under this Agreement.

(vi) If by the Maturity Date for any reason or for no reason the full Available Amount under this Agreement has not been purchased as provided for in Section 2 of this Agreement, this Agreement shall automatically terminate on the Maturity Date, without any action or notice on the part of any party and without any liability whatsoever of any party to any other party under this Agreement.

Except as set forth in Sections 11(k)(i) (in respect of an Event of Default under Sections 10(f), 10(g) and 10(h)) and 11(k)(vi), any termination of this Agreement pursuant to this Section 11(k) shall be effected by written notice from the Company to the Investor, or the Investor to the Company, as the case may be, setting forth the basis for the termination hereof. The representations and warranties of the Company and the Investor contained in Sections 3, 4 and 6 hereof, the indemnification provisions set forth in Section 9 hereof and the agreements and covenants set forth in Section 11, shall survive the Commencement and any termination of this Agreement. No termination of this Agreement shall affect the Company’s or the Investor’s rights or obligations (i) under the Registration Rights Agreement which shall survive any such termination or (ii) under this Agreement with respect to pending purchases or Additional Purchases and the Company and the Investor shall complete their respective obligations with respect to any pending purchases or Additional Purchases under this Agreement.

(m) No Financial Advisor, Placement Agent, Broker or Finder. The Company represents and warrants to the Investor that it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby. The Investor represents and warrants to the Company that it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby. The Company shall be responsible for the payment of any fees or commissions, if any, of any financial advisor, placement agent, broker or finder relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold the Investor harmless against, any liability, loss or expense (including, without limitation, attorneys’ fees and out of pocket expenses) arising in connection with any such claim.

(n) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(o) Remedies, Other Obligations, Breaches and Injunctive Relief. The parties’ remedies provided in this Agreement shall be cumulative and in addition to all other remedies available to them under this Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), no remedy of the parties contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy and nothing herein shall limit the parties’ right to pursue actual damages for any failure by the other party to comply with the terms of this Agreement. Each party acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the the other party and that the remedy at law for any such breach may be inadequate. Each party therefore agrees that, in the event of any such breach or threatened breach, the other party shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

(p) Enforcement Costs. If: (i) this Agreement is placed by a party (the “enforcing party”) in the hands of an attorney for enforcement or is enforced by the enforcing party through any legal proceeding; or (ii) an attorney is retained to represent the enforcing party in any bankruptcy, reorganization, receivership or other proceedings affecting creditors’ rights and involving a claim under this Agreement; or (iii) an attorney is retained to represent the enforcing party in any other proceedings whatsoever in connection with this Agreement, then the other party shall pay to the enforcing party, as incurred by the enforcing party, all reasonable costs and expenses including attorneys’ fees incurred in connection therewith, in addition to all other amounts due hereunder.

(q) Failure or Indulgence Not Waiver. No failure or delay in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.
