Amendment No. 2 to Securities Purchase Agreement, Senior Secured Convertible Notes and Warrants

The Company and the Purchasers are parties to a Securities Purchase Agreement, dated as of March 20, 2006 (the “Purchase Agreement”), as amended by Amendment No. 1 to Senior Secured Convertible Notes, Warrants, Additional Investment Rights and Security Agreement dated as of September 6, 2006 (“Amendment No. 1”) pursuant to which the Company issued and sold to the Purchasers an aggregate of $3,781,662 of Senior Secured Convertible Notes due January 1, 2008 (the “Notes”) and certain Warrants and Additional Investment Rights (each as defined in the Purchase Agreement). Capitalized terms used and not defined in this Amendment shall have the respective meanings set forth in the Purchase Agreement or Notes, as the case may be.

In connection with Amendment No. 1, the principal amount of the Notes consists of (i) $2,500,000 of Senior Secured Convertible Notes issued on March 20, 2006 (the “Original Notes”), (ii) $1,000,000 of Senior Secured Convertible Notes issued pursuant to Amendment No. 1, and (iii) $281,662 of accrued interest and liquidated damages.

In connection with Amendment No. 1, the Warrants and Additional Investment Rights consist of (i) the original warrants and additional investment rights issued under the Purchase Agreement on March 20, 2006 (the “Original Warrants” and the “Original Additional Investment Rights”, respectively), and (ii) the warrants and additional investment rights issued under Amendment No. 1.

The Company and the Purchasers now wish to further modify certain terms of the Purchase Agreement, Notes and Warrants.

Amendments and Agreements.

The Company and each Purchaser agrees that Section 2(b) of the Notes shall be deleted and replaced in its entirety as follows:

The Company hereby acknowledges, and shall cause its counsel to issue a legal opinion to the Purchasers, that (i) the Common Stock issuable upon conversion of the Notes up to the principal amount of the Original Notes and the Common Stock issuable upon a cashless exercise of the Original Warrants (to the extent permitted) shall be eligible to be sold under Rule 144 on March 20, 2007, and (ii) the Common Stock issuable upon conversion of all the Notes and the Common Stock issuable upon a cashless exercise of all the warrants (to the extent permitted) issued under Amendment No. 1 shall be eligible to be sold under Rule 144 on September 6, 2007.

Following March 20, 2007, if the Company issues any Common Stock as a Monthly Installment that is not eligible for resale under Rule 144 and the Registration Statement is not effective (any such shares issued, the “Restricted Shares”), then (x) the number of shares of Common Stock that are issued to each Purchaser as principal shall be adjusted so that the number of shares of Common Stock such Purchaser receives is equal to the quotient obtained by dividing the total principal then payable to such Purchaser by the Issue Price, and (y) each Purchaser shall have the right to require the Company to repurchase (the “Repurchase Option”) in cash all or any portion of such Restricted Shares, within 10 Trading Days following delivery by such Purchaser of a notice to the Company, at a price equal to 130% of the Issue Price. A Purchaser shall not be permitted to exercise its Repurchase Option if at the time of the delivery by such Purchaser of the notice to the Company the Restricted Shares can be sold under Rule 144 (and Company’s counsel has

provided the requisite legal opinion for the sale of such shares pursuant to Rule 144, at a cost born solely by the Company) or a Registration Statement is effective. For the purposes of this Amendment, the “Issue Price” shall mean the lowest of (i) the Conversion Price, (ii) $0.80, and (iii) the Market Price as of the applicable Principal Payment Date (as defined in the Notes), and rounding up to the nearest whole share.

The Purchasers agree that any amounts due under Section 6.1(d) of the Purchase Agreement shall only apply to Events occurring on or after April 30, 2007, except as otherwise set forth in this Amendment.

Additional Warrants.

In connection with the transaction contemplated by this Amendment, the Company agrees to issue to each Purchaser a warrant in the form of Exhibit A hereto (the “Additional Warrant A”), registered in the name of such Purchaser, pursuant to which such Purchaser shall have the right to acquire such number of Underlying Shares indicated on Schedule A hereto under the heading “Additional Warrant A Shares”.

Registration Rights. To ensure that the registration rights of the Purchasers are not adversely affected as a result of the transactions contemplated by this Amendment and to provide registration rights consistent with the existing registration rights in respect of the Common Stock issuable upon exercise of the Securities, the parties agree as follows with respect to registration rights.

The Company and each Purchaser agrees that the first sentence of Section 6.1(a) of the Purchase Agreement shall be deleted and replaced in its entirety as follows:

The parties hereby agree that the definition of “Registrable Securities” under the Purchase Agreement shall include (a) the shares of Common Stock issuable upon the conversion or exercise of the Notes, Warrants, Additional Warrants and Additional Investment Rights, and (b) any Common Stock (including Underlying Shares) issued or issuable pursuant to the Transaction Documents, Amendment No. 1 and this Amendment, together with any securities issued or issuable upon any stock split, dividend or other distribution, recapitalization or similar event with respect to the foregoing.

The Company will use commercially reasonable efforts to prepare and file the

Registration Statement to cover all shares of Common Stock issuable under this Amendment, Amendment No. 1 and the Transaction Documents, including the Registrable Securities.

The Filing Date with respect to the initial Registration Statement shall be April 30, 2007 and the Required Effectiveness Date with respect to the initial Registration Statement shall be the earlier of (i) July 31, 2007 and (ii) the fifth Trading Day following the date on which the Company is notified by the Commission that the initial Registration Statement will not be reviewed or is no longer subject to further review and comments. Notwithstanding anything to the contrary herein, a breach of this Section 3.4 shall subject the Company to amounts due under Section 6.1(d) of the Purchase Agreement.

In addition to any amounts due under Section 6.1(d) of the Purchase Agreement, if the Company fails to file the Registration Statement by April 30, 2007, then the Company agrees to issue to each Purchaser on May 1, 2007 an additional warrant in the form of Exhibit B hereto (the “Additional Warrant B” and together with the Additional Warrant A, the “Additional Warrants”), registered in the name of such Purchaser, pursuant to which such Purchaser shall have the right to acquire such number of Underlying Shares indicated on Schedule A hereto under the heading “Additional Warrant B Shares”.

Charter Amendment.

The Company shall use its best efforts to obtain as soon as possible, but in no event later than June 30, 2007, shareholder approval of the Charter Amendment (the “Charter Amendment Approval Date”). If the Charter Amendment fails to be declared effective on or prior to the Charter Amendment Approval Date and the Company does not have shares available to be issued upon exercise of Warrants or Additional Warrants elected by the Purchasers to be exercised or Notes elected by the Purchasers to be converted, such failure shall be deemed an “Event” under Section 6.1(d) of the Purchase Agreement. For the purposes of this Amendment, “Charter Amendment” shall mean an amendment of the Certificate of Incorporation of the Company, duly approved by the stockholders of the Company, which amendment increases the authorized number of shares of Common Stock of the Company, $.002 par value, to a minimum of 200,000,000 shares.

As soon as practicable following the date hereof, but in no event later than March 31, 2007, the Company shall prepare and file with the Commission proxy materials calling a special meeting or general meeting (the "Meeting") of its shareholders seeking approval of the Charter Amendment. The Company shall use its reasonable best efforts to cause such proxy materials to reach the "no further comment" stage as soon as possible (the "Clearance Date") and to hold the Meeting as soon as possible following the Clearance Date, but in no event later than 60 days

following the Clearance Date.

The Board of Directors shall recommend approval of the Charter Amendment to the Company's shareholders. The Company shall mail and distribute its proxy materials for the Meeting to its shareholders at least 30 days prior to the date of the Meeting and shall actively solicit proxies to vote for the Charter Amendment. The Company shall provide the Purchasers an opportunity to review and comment on such proxy materials by providing (which may be by e-mail) copies of such proxy materials and any revised preliminary proxy materials to the Purchasers at least three (3) days prior to their filing with the Commission. The Company shall provide the Purchasers (which may be by e-mail) copies of all correspondence from or to the Commission or its staff concerning the proxy materials for the Meeting promptly after the same is sent or received by the Company and summaries of any comments of the Commission's staff which the Company receives orally promptly after receiving such oral comments. The Company shall (i) furnish to the Purchasers and their counsel (which may be by e-mail) a copy of its definitive proxy materials for the Meeting and any amendments or supplements thereto promptly after the same are first used, mailed to shareholders or filed with the Commission, (ii) inform the Purchasers of the progress of solicitation of proxies for such Meeting and (iii) inform the Purchasers of any adjournment of the Meeting and shall report the result of the vote of shareholders on the Charter Amendment at the conclusion of the Meeting. In connection with the Meeting, the Company shall hire, at its expense, a nationally recognized proxy solicitation firm, selected by the Purchasers, to assist it in obtaining the necessary shareholder votes to approve the Charter Amendment.

If for any reason the Charter Amendment is not approved at the Meeting, the Company will take such additional acts or actions as are necessary to hold an additional Meeting to consider the Charter Amendment and in conjunction therewith shall hire a nationally recognized proxy solicitation firm, selected by the Purchasers which is reasonably satisfactory to the Company, to assist it in obtaining the necessary shareholder votes to approve the Charter Amendment. Such additional Meetings shall be held no less frequent than every 3 months until such Charter Amendment is approved or the Notes and Warrants are no longer outstanding. The Company shall bear all costs and expenses of the preparation and filing of any and all proxy materials and Meetings, including but not limited to the costs and expenses of the proxy solicitation firm if needed.

In the event the Charter Amendment is not approved by the Charter Amendment Approval Date and the Company does not have shares available to be issued upon exercise of Warrants or Additional Warrants elected by the Purchasers to be exercised or Notes elected by the Purchasers to be converted, in addition to the other remedies available to the Purchasers, the Purchasers shall have the right to require the Company

Continued Validity of Transaction Documents under the Purchase Agreement; Waiver of Prior Defaults. The parties hereto agree that the Purchase Agreement and the other Transaction Documents entered into in connection therewith (as amended by this Amendment), remain in full force and effect, modified to the extent and only to the extent necessary to give effect to this Amendment and the transactions herein contemplated. The parties agree that any default or event of default that has occurred, prior to the effective date hereof, under any of the Transaction Documents is waived by each of the Purchasers.

The Company hereby represents and warrants to the Purchasers that each of the representations and warrants set forth in Section 3.1 of the Purchase Agreement are true and correct as of the date hereof.

Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (i) as required by federal securities law in connection with the registration statement contemplated by the Purchase Agreement and (ii) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under subclause (i) or (ii).

Notices.

Amendments; Waivers.

No waiver of any default with respect to any provision, condition or requirement of this Amendment shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.
