12. Registration Rights.

12.1. Registration Statement. The Company shall file with the Commission a Form S-3 registration statement (or such other form that it is eligible to use) (the “Registration Statement”) in order to register the Registrable Securities (as hereinafter defined) for resale and distribution under the 1933 Act within forty five (45) calendar days after the final Closing Date (the “Filing Date”), and use its reasonable best efforts to cause such Registration Statement to be declared effective not later than ninety (90) calendar days after the Filing Date (the “Effective Date”). The Company will register not less than a number of shares of common stock in the Registration Statement that is equal to 100% of the Shares issuable upon conversion of all of the Preferred Stock issuable to the Subscribers, and 100% of the Warrant Shares issuable pursuant to the Warrants upon exercise of the Warrants (collectively the “Registrable Securities”). The Registrable Securities shall be reserved and set aside exclusively for the benefit of each Subscriber and Warrant holder, pro rata, and not issued, employed or reserved for anyone other than each such Subscriber and Warrant holder. The Registration Statement will immediately be amended or additional registration statements will be immediately filed by the Company as necessary to register additional shares of Common Stock to allow the public resale of all Common Stock included in and issuable by virtue of the Registrable Securities.

12.2. Registration Procedures. If and whenever the Company is required by the provisions of this Section to effect the registration of any Registrable Securities under the 1933 Act, the Company will, as expeditiously as possible:

(a) subject to the timelines provided in this Agreement, prepare and file with the Commission a registration statement required by Section 10, with respect to such securities and use its best efforts to cause such registration statement to become and remain effective for the period of the distribution contemplated thereby (determined as herein provided), promptly provide to the holders of the Registrable Securities copies of all filings and Commission letters of comment and notify Subscribers (by telecopier or by email ) on or before 6:00 PM EST not later than the second business day after the Company receives notice that (i) the Commission has no comments or no further comments on the Registration Statement, and (ii) the registration statement has been declared effective;

12

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until such registration statement has been effective for a period of two (2) years, and comply with the provisions of the 1933 Act with respect to the disposition of all of the Registrable Securities covered by such registration statement in accordance with the Sellers’ intended method of disposition set forth in such registration statement for such period;

(c) furnish to the Sellers, at the Company’s expense, such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or their disposition of the securities covered by such registration statement or make them electronically available;

(d) use its commercially reasonable best efforts to register or qualify the Registrable Securities covered by such registration statement under the securities or “blue sky” laws of such jurisdictions as the Sellers shall reasonably request in writing, provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction;

(e) if applicable, list the Registrable Securities covered by such registration statement with any securities exchange on which the Common Stock of the Company is then listed; and

(f) notify the Subscribers of the Company’s becoming aware that a prospectus relating thereto is required to be delivered under the 1933 Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing or which becomes subject to a Commission, state or other governmental order suspending the effectiveness of the registration statement covering any of the Shares.

12.3. Provision of Documents. In connection with each registration described in this Section 12, each Seller will furnish to the Company in writing such information and representation letters with respect to itself and the proposed distribution by it as reasonably shall be necessary in order to assure compliance with federal and applicable state securities laws. The Company’s obligation to register each Subscriber’s Registrable Securities is subject to

12.4. Non-Registration Events. The Company and the Subscribers agree that the Sellers will suffer damages if the Registration Statement is not filed by the Filing Date and not declared effective by the Commission by the Effective Date, and maintained in the manner and within the time periods contemplated by Section 12 hereof, and it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if (A) the Registration Statement is not filed on or before the Filing Date, (B) is not declared effective on or before the Effective Date, or (C) the Registration Statement is filed and declared effective but shall thereafter cease to be effective without being succeeded within fifteen (15) business days by an effective replacement or amended registration statement or for a period of time which shall exceed 30 days in the aggregate per year (defined as a period of 365 days commencing on the Actual Effective Date (each such event referred to in clauses (A) through (C) of this Section 12.4 is referred to herein as a “Non-Registration Event”), then the Company shall deliver to the holder of Registrable Securities, as Liquidated Damages, an amount equal to one and one half percent (1.5%) for each thirty (30) days or part thereof of the Purchase Price of the Preferred Stock remaining unconverted and purchase price of Shares issued upon conversion of the Obligation Amount (as defined in

13

the Certificate of Designation) owned of record by such holder which are subject to such Non-Registration Event. The Company must pay the Liquidated Damages in cash. The Liquidated Damages must be paid within ten (10) days after the end of each thirty (30) day period or shorter part thereof for which Liquidated Damages are payable. Notwithstanding the foregoing, the Company shall not be liable to a Subscriber under this Section 12.4 for any events or delays occurring as a consequence of the acts or omissions of the Subscribers contrary to the obligations undertaken by Subscribers in this Agreement. Liquidated Damages will not accrue nor be payable pursuant to this Section 12.4 nor will a Non-Registration Event be deemed to have occurred for times during which Registrable Securities are transferable by the holder of Registrable Securities pursuant to Rule 144(k) under the 1933 Act.

12.5. Expenses. All expenses incurred by the Company in complying with Section 10, including, without limitation, all registration and filing fees, printing expenses (if required), fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including reasonable counsel fees) incurred in connection with complying with state securities or “blue sky” laws, fees of the National Association of Securities Dealers, Inc., transfer taxes, and fees of transfer agents and registrars, are called “Registration Expenses.” All selling commissions applicable to the sale of Registrable Securities are called “Selling Expenses.” The Company will pay all Registration Expenses in connection with the registration statement under Section 12. The Sellers shall be responsible for Selling Expenses attributable to the sale of their respective Securities.

12.6. Indemnification and Contribution.

(a) In the event of a registration of any Registrable Securities under the 1933 Act pursuant to Section 12, the Company will, to the extent permitted by law, indemnify and hold harmless each Subscriber whose securities are included in the Registration Statement (each, a “Seller”), each officer of the Seller, each director of the Seller, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls such Seller or underwriter within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which the Seller, or such underwriter or controlling person may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities was registered under the 1933 Act pursuant to Section 12, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances when made, and will subject to the provisions of Section 12.6(c) reimburse the Seller, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable to the Seller to the extent that any such damages arise out of or are based upon an untrue statement or omission made in any preliminary prospectus if (i) the Seller failed to send or deliver a copy of the final prospectus delivered by the Company to the Seller with or prior to the delivery of written confirmation of the sale by the Seller to the person asserting the claim from which such damages arise, (ii) the final prospectus would have corrected such untrue statement or alleged untrue statement or such omission or alleged omission, or (iii) to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by any Seller, or any such controlling person in writing specifically for use in such registration statement or prospectus.

14

(b) In the event of a registration of any of the Registrable Securities under the 1933 Act pursuant to Section 12, each Seller severally but not jointly will, to the extent permitted by law, indemnify and hold harmless the Company, and each person, if any, who controls the Company within the meaning of the 1933 Act, each officer of the Company who signs the registration statement, each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the 1933 Act, against all losses, damages or liabilities, joint or several, to which the Company or such officer, director, underwriter or controlling person may become subject under the 1933 Act or otherwise, insofar as such losses, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the 1933 Act pursuant to Section 12, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer, director, underwriter and controlling person after a non-appealable judgment or determination for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, damage, liability or action, provided, however, that the Seller will be liable hereunder in any such case if and only to the extent that any such loss, damage or liability arises out of or is based solely upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such Seller, as such, furnished in writing to the Company by such Seller specifically for use in such registration statement or prospectus, and provided, further, however, that the liability of the Seller hereunder shall be limited to the net proceeds actually received by the Seller from the sale of Registrable Securities covered by such registration statement.

(c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 12.6(c) and shall only relieve it from any liability which it may have to such indemnified party under this Section 12.6(c), except and only if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 12.6(c) for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified parties, as a group, shall have the right to select one separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred.

13. Prohibition Against Conversion Right. Notwithstanding anything to the contrary in Section 7(b) of the Certificate of Designation, the Company agrees and acknowledges that it shall not require the Subscriber or any assignee, purchaser or other transferee of Preferred Stock to convert their Preferred Stock into Common Stock in accordance with Section 7(b)(i) of the Certificate of Designation. Any notice of or action to effect conversion of such Preferred Stock pursuant to Section 7(b)(i) of the Certificate of Designation shall be null and void.
