Such Registration Statement shall include a plan of distribution, which shall be substantially in the form attached hereto as Exhibit A. Such Registration Statement shall also cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. The Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided in accordance with Section 3(c) to the Investors and their counsel prior to its filing or other submission. If a Registration Statement covering the Registrable Securities is not filed with the SEC on or prior to the Filing Deadline or the Dismissal Deadline, as applicable, the Company will make pro rata payments to each Investor, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount invested by such Investor for each 30-day period or pro rata for any portion thereof following the Filing Deadline or Dismissal Deadline, as applicable, for which no Registration Statement is filed with respect to the Registrable Securities. Such payments shall be in partial compensation to the Investors, and shall not constitute the Investors’ exclusive remedy for such events. Such payments shall be made to each Investor in cash or additional shares of Common Stock, as determined by each Investor, and shall be paid monthly within three (3) Business Days after the last day of each month following the Filing Deadline.

               (ii) Additional Registrable Securities. Upon the written demand of any Investor and upon any change in the Exercise Price (as defined in the Warrants and the Placement Agent Warrants, respectively) such that additional shares of Common Stock become issuable upon the exercise of the Warrants and/or Placement Agent Warrants, the Company shall prepare and file with the SEC one or more Registration Statements on Form S-3 or amend or supplement the Registration Statement filed pursuant to clause (i) above, if such Registration Statement has not previously been declared effective (or, if Form S-3 is not then available to the Company, on such form of registration statement as is then available to effect a registration for

resale of such additional shares of Common Stock (the “Additional Shares”), subject to the Required Investors’ consent, covering the sale or the resale of the Additional Shares, but only to the extent the Additional Shares are not at the time covered by an effective Registration Statement. Such Registration Statement also shall cover, to the extent allowable under the 1933 Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the Additional Shares. The Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided in accordance with Section 3(c) to the Investors and their counsel prior to its filing or other submission. If a Registration Statement covering the Additional Shares is required to be filed under this Section 2(a)(ii) and is not filed with the SEC within five (5) Business Days after the request of any Investor or the occurrence of any of the events specified in this Section 2(a)(ii), but in no event earlier than the Filing Deadline, (the “Additional Shares Deadline”), then the Company will, for each 30-day period or pro rata for any portion thereof following the date by which such Registration Statement should have been filed for which no Registration Statement is filed with respect to the Additional Shares, make pro rata payments to each Investor, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the prorated aggregate amount invested by such Investor and that is attributable to the Additional Shares. By way of example only, if an Investor purchased Registrable Securities representing 300,000 shares and subsequently received 100,000 Additional Shares, the liquidated damages due on passage of the Additional Shares Deadline would be calculated with reference to one-quarter of the total amount invested by that Investor (i.e., 100,000/400,000, where 400,000 is calculated by adding 100,000 and 300,000). Such payments shall be in partial compensation to the Investors, and shall not constitute the Investors’ exclusive remedy for such events. Such payments shall be made to each Investor in cash or additional shares of Common Stock, as determined by each Investor, and shall be paid monthly within three (3) Business Days after the last day of each month following the Additional Shares Deadline.

               (iii) S-3 Qualification. If the Company is not eligible to use a registration statement on Form S-3 as provided in Sections 2(a)(i) and 2(a)(ii) above, then, promptly following the date (the “Qualification Date”) upon which the Company becomes eligible to use a registration statement on Form S-3 to register the Registrable Securities or Additional Shares, as applicable, for resale, but in no event more than forty-five (45) days after the Qualification Date (the “Qualification Deadline”), the Company shall file a registration statement on Form S-3 covering the Registrable Securities or Additional Shares, as applicable (or a post-effective amendment on Form S-3 to the registration statement on Form S-1) (a “Shelf Registration Statement”) and shall use commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective as promptly as practicable thereafter. If a Shelf Registration Statement covering the Registrable Securities is not filed with the SEC on or prior to the Qualification Deadline, the Company will make pro rata payments to each Investor, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount invested by such Investor for each 30-day period or pro rata for any portion thereof following the date by which such Shelf Registration Statement should have been filed for which no such Shelf Registration Statement is filed with respect to the Registrable Securities or Additional Shares, as applicable. Such payments shall be in partial compensation to the Investors, and shall not constitute the Investors’ exclusive remedy for such events. Such payments shall be made to each Investor in cash or additional shares of Common Stock, as determined by each Investor, and shall be paid monthly within three (3) Business Days after the last day of each month following the Qualification Deadline.

               (b) Expenses. The Company will pay all expenses associated with each registration, including filing and printing fees, the Company’s counsel and accounting fees and expenses, costs associated with clearing the Registrable Securities for sale under applicable state securities laws, listing fees, and fees and reasonable expenses of one counsel to the Investors. Other than the above, the Investors shall bear their respective expenses in connection with the registration, including, without limitation, discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold.

               (c) Effectiveness.

               (i) The Company shall use commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable. The Company shall notify the Investors by facsimile or e-mail as promptly as practicable, and in any event, within twenty-four (24) hours, after any Registration Statement is declared effective and shall simultaneously provide the Investors with copies of any related Prospectus to be used in connection with the sale or other disposition of the securities covered thereby. If (A)(x) a Registration Statement covering the Registrable Securities is not declared effective by the SEC prior to the earlier of (i) ten (10) Business Days after the SEC has notified the Company that no review of the Registration Statement will be made or (ii) within ninety (90) days after the Filing Deadline or the Dismissal Deadline (if applicable), (y) a Registration Statement covering Additional Shares is not declared effective by the SEC within ninety (90) days after the Additional Shares Deadline or (z) a Shelf Registration Statement is not declared effective by the SEC within ninety (90) days after the Qualification Deadline, or (B) after a Registration Statement has been declared effective by the SEC, sales cannot be made pursuant to such Registration Statement for any reason (including without limitation by reason of a stop order, or the Company’s failure to update the Registration Statement), but excluding the inability of any Investor to sell the Registrable Securities covered thereby due to market conditions and except as excused pursuant to subparagraph (ii) below, then the Company will make pro rata payments to each Investor, as liquidated damages and not as a penalty, in an amount equal to 1.0% of the aggregate amount invested by such Investor for each 30-day period or pro rata for any portion thereof following the date by which such Registration Statement should have been effective (the “Blackout Period”). Such payments shall be in partial compensation to the Investors, and shall not constitute the Investors’ exclusive remedy for such events. The amounts payable as liquidated damages pursuant to this paragraph shall be paid monthly within three (3) Business Days after the last day of each month following the commencement of the Blackout Period until the termination of the Blackout Period. Such payments shall be made to each Investor in cash or in additional shares of Common Stock as determined by each Investor.

               (ii) For not more than twenty (20) consecutive days or for a total of not more than forty-five (45) days in any twelve (12) month period, the Company may delay the disclosure of material non-public information concerning the Company, by suspending the use of any Prospectus included in any registration contemplated by this Section containing such information, the disclosure of which at the time is not, in the good faith opinion of the Company, in the best interests of the Company (an “Allowed Delay”); provided, that the Company shall promptly (a) notify the Purchasers and the Placement Agent in writing of the existence of (but in no event, without the prior written consent of a Purchaser and the Placement Agent, shall the Company disclose to such Investor any of the facts or circumstances regarding) material non-public information giving rise to an Allowed Delay, (b) advise the Purchasers and the Placement

Agent in writing to cease all sales under the Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.

               (i) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the SEC under the 1933 Act and the 1934 Act, take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder; and make available to its security holders, as soon as reasonably practicable, but not later than the Availability Date (as defined below), an earnings statement covering a period of at least twelve (12) months, beginning after the effective date of each Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the 1933 Act, including Rule 158 promulgated thereunder (for the purpose of this subsection 3(i), “Availability Date” means the 45th day following the end of the fourth fiscal quarter that includes the effective date of such Registration Statement, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” shall mean the 90th day after the end of such fourth fiscal quarter); provided, however, that the filing of any such earnings statement in a periodic report filed with the SEC shall satisfy the Company’s obligations under this Section 3(i).

     6. Indemnification.

               (a) Indemnification by the Company. The Company will indemnify and hold harmless each Investor and their respective officers, directors, members, employees and agents, successors and assigns, and each other person, if any, who controls such Investor within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they 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: (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof; (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof; (iii) 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; (iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; or (v) any failure to register or qualify the Registrable Securities included in any such Registration in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such registration or qualification on an Investor’s behalf and will reimburse such Investor, and each such officer, director or member 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 will not be liable in any such case if and 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 such Investor or any such controlling person in writing specifically for use in such Registration Statement or Prospectus.

               (b) Indemnification of the Company. Each Investor agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Investor in

connection with any claim relating to this Section 6 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation.

               (c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation.

               (d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

Exhibit A

Plan of Distribution

     The selling stockholders (the “Selling Stockholders”, which as used herein includes donees, pledgees, transferees or other successors-in-interest of a Selling Stockholder selling shares of Common Stock or interests in shares of Common Stock received after the date of this prospectus from a Selling Stockholder as a gift, pledge, partnership distribution or other transfer) may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of Common Stock or interests in shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

     The Selling Stockholders may use any one or more of the following methods when disposing of shares or interests therein:

     – ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

     – block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

     – purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

     – an exchange distribution in accordance with the rules of the applicable exchange;

     – privately negotiated transactions;

     – short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the SEC;

     – through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

     – broker-dealers may agree with the Selling Stockholders to sell a specified number of such shares at a stipulated price per share; and

     – a combination of any such methods of sale.

     The Selling Stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock, from time to time, under this Prospectus, or under an amendment to this Prospectus under Rule 424(b)(3) or other applicable provision of the 1933 Act amending the list of Selling Stockholders to include the pledgee, transferee or other successors-in-interest as Selling Stockholders under this Prospectus. The Selling Stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this Prospectus.

     Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Stockholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

     Spencer Trask Ventures, Inc. (“STVI”) has indicated to us its willingness to act as selling agent on behalf of the Selling Stockholders named in the Prospectus under “Selling Security Holders” that purchased our privately placed securities. All shares sold, if any, on behalf of Selling Stockholders by STVI would be in transactions executed by STVI on an agency basis and commissions charged to its customers in connection with each transaction shall not exceed a maximum of 5% of the gross proceeds. STVI does not have an underwriting agreement with us and/or the Selling Stockholders and no Selling Stockholders are required to execute transactions through STVI. In the event that there are other broker-dealer firms involved in the distribution of securities on behalf of the Selling Stockholders, the maximum commission or discount to be received will not be greater than 8% of the sale of any securities which were registered pursuant to this Prospectus under SEC Rule 415.

     In connection with the sale of our Common Stock or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The Selling Stockholders may also sell shares of our Common Stock short and deliver these securities to close out their short positions, or loan or pledge the Common Stock to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this Prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this Prospectus (as supplemented or amended to reflect such transaction).

     The Selling Stockholders will receive the aggregate proceeds from the sale of the Common Stock offered by them. The aggregate proceeds to the Selling Stockholders from the sale of the Common Stock offered by them will be the purchase price of the Common Stock less discounts or commissions, if any. Each of the Selling Stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of Common Stock to be made directly or through agents. We will not receive any of the proceeds from the sale of Common Stock in this offering. We may receive proceeds from holders who exercise their warrants and pay the applicable cash exercise price in connection with those exercises.

     The Selling Stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule.

     The Selling Stockholders and any underwriters, broker-dealers or agents that participate in the sale of the Common Stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the 1933 Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the 1933 Act.

Selling Stockholders who are “underwriters” within the meaning of Section 2(11) of the 1933 Act will be subject to the prospectus delivery requirements of the 1933 Act.

     To the extent required, the shares of our Common Stock to be sold, the names of the Selling Stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this Prospectus.

     In order to comply with the securities laws of some states, if applicable, the Common Stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Common Stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

     We have advised the Selling Stockholders that the anti-manipulation rules of Regulation M under the 1934 Act may apply to sales of shares in the market and to the activities of the Selling Stockholders and their affiliates. In addition, we will make copies of this Prospectus (as it may be supplemented or amended from time to time) available to the Selling Stockholders for the purpose of satisfying the prospectus delivery requirements of the 1933 Act. The Selling Stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares of Common Stock against certain liabilities, including liabilities arising under the 1933 Act.

     We will pay all of the expenses incident to registration other than commissions, fees and discounts of underwriters, brokers, dealers and agents. We will pay for offering expenses including the SEC registration fee, accounting fees, legal fees, printing expenses and other related miscellaneous expenses. We have agreed to indemnify the Selling Stockholders against liabilities, including liabilities under the 1933 Act and state securities laws, relating to the registration of the shares offered by this Prospectus.

     We have agreed with the Selling Stockholders to keep the registration statement of which this Prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this Prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the 1933 Act. Notwithstanding anything contained herein to the contrary, an aggregate of ___ shares of Common Stock issuable upon exercise of warrants held by “associated persons” of STVI are subject to a 180 day lock-up agreement in accordance with the requirements of NASD Rule 2710(g)(1).
