From the date of this Agreement and until the sooner of (i) two (2) years after the Closing Date, or (ii) until all the Shares and Warrant Shares have been resold or transferred by all the Subscribers pursuant to the Registration Statement or pursuant to Rule 144, without regard to volume limitations, the Company agrees that it will not disclose publicly or privately the identity of the Subscribers unless expressly agreed to in writing by a Subscriber or only to the extent required by law and then only upon ten days prior notice to Subscriber. The Company may identify the Subscribers in any registration statement filed pursuant to Section 11 of this Agreement. Notwithstanding the foregoing, the Company undertakes to file a Form 8-K describing the Offering not later than the Closing Date. In the Form 8-K, the Company will specifically disclose the amount of common stock outstanding immediately after the Closing. In addition, it is acknowledged by the parties hereto that the Company shall file copies of this Agreement, the Warrants and the Placement Agent Warrant as material contracts in its filings with the Securities and Exchange Commission.

(n) Further Registration Statements. Except for a registration statement filed on behalf of the Subscribers pursuant to Section 11 of this Agreement or as otherwise set forth on Schedule 9(n), the Company will not file any registration statements, including but not limited to Form S-8, with the Commission or with state regulatory authorities without the consent of the Subscribers holding 75% of the Shares sold hereunder including any Warrant Shares, if any (the “Applicable Percentage”) until 90 (90) days after the effective date of the Registration Statement filed on behalf of the Subscribers during which such Registration Statement shall be current and available for use in connection with the public resale of the Shares and Warrant Shares (“Exclusion Period”).

(o) Blackout. The Company undertakes and covenants that without the consent of the Applicable Percentage of the Subscribers which consent shall not be unreasonably withheld, until the first to occur of (i) the end of the Exclusion Period, or (ii) until all the Shares and Warrant Shares have been resold pursuant to such registration statement, the Company will not enter into any acquisition, merger, exchange or sale or other transaction that could have the effect of delaying the effectiveness of any pending registration statement or causing an already effective registration statement to no longer be effective or current.

10. Covenants of the Company and Subscribers Regarding Indemnification.

(a) The Company agrees to indemnify, hold harmless, reimburse and defend the Subscribers, the Subscribers’ officers, directors, agents, affiliates, control persons, and principal shareholders, against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed upon the Subscriber or any such person which results, arises out of or is based upon (i) any material misrepresentation by Company or breach of any warranty by Company in this Agreement or in any Exhibits or Schedules attached hereto, or other agreement delivered pursuant hereto; or (ii) after any applicable notice and/or cure periods, any breach or default in performance by the Company of any covenant or undertaking to be performed by the Company hereunder, or any other agreement entered into by the Company and any Subscriber or the Subscribers relating hereto.

(b) Each Subscriber agrees to indemnify, hold harmless, reimburse and defend the Company and each of the Company’s officers, directors, agents, affiliates, control persons against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed upon the Company or any such person which results, arises out of or is based upon (i) any material misrepresentation by such Subscriber in this Agreement or in any Exhibits or Schedules attached hereto, or other agreement delivered pursuant hereto; or (ii) after any applicable notice and/or cure periods, any breach or default in performance by such Subscriber of any covenant or undertaking to be performed by such Subscriber hereunder, or any other agreement entered into by the Company and Subscribes relating hereto.

(c) In no event shall the liability of any Subscriber or permitted successor hereunder or under any other agreement delivered in connection herewith be greater in amount than the dollar amount of the net proceeds actually received by such Subscriber upon the sale of Shares or Shares issuable upon exercise of Warrants (“Registrable Securities”).

(d) The procedures set forth in Section 11.6 shall apply to the indemnifications set forth in Sections 10(a) and 10(b) above.

11.1. Registration Rights. The Company hereby grants the following registration rights to holders of the Securities.

(i) Not later than 30 days after the Closing Date (the “Filing Date”), the Company shall prepare and file with the Commission a registration statement under the 1933 Act registering the Shares and Warrant Shares including Warrant Shares issuable upon exercise of the Placement Agent’s Warrants (collectively “Registrable Securities”) for unrestricted public resale by the holder thereof. The Company will cause such registration statement to be declared effective within 90 days after the Closing Date (the “Effective Date”), a Form SB-3 registration statement (the “Registration Statement”) (or such other form that it is eligible to use) in order to register the Registrable Securities for resale and distribution under the 1933 Act. The Company will register not less than a number of shares of common stock that is equal to all of the Shares and Warrant Shares issuable pursuant to this Agreement. 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. Without the written consent of the Applicable Percentage of the Subscribers, no securities of the Company other than the Registrable Securities will be included in the Registration Statement.

12

11.2. Registration Procedures. If and whenever the Company is required by the provisions of Section 11.1(i) 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 11, 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), and promptly provide to the holders of Registrable Securities copies of all filings and Commission letters of comment;

(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 Subscribers’ intended method of disposition set forth in such registration statement for such period;

(c) furnish to the Subscribers, 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;

(d) use its best efforts to register or qualify the Sunscribers’ Registrable Securities covered by such registration statement under the securities or “blue sky” laws of such jurisdictions as the Subscribers shall 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;

(f) immediately notify the Subscribers when 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; and

(g) provided same would not be in violation of the provision of Regulation FD under the 1934 Act, make available for inspection by the Subscribers, and any attorney, accountant or other agent retained by the Subscriber or underwriter, all publicly available, non-confidential financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and employees to supply all publicly available, non-confidential information reasonably requested by the seller, attorney, accountant or agent in connection with such registration statement.

11.3. Provision of Documents. In connection with each registration described in this Section 11, each Subscriber 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.

11.4. Non-Registration Events. The Company and the Subscribers agree that the Subscribers will suffer damages if the Registration Statement is not filed by the Filing Date and not

13

declared effective by the Commission by the Effective Date, and it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if (i) the Registration Statement is not filed on or before the Filing Date or is not declared effective on or before the sooner of the Effective Date, or within three (3) business days of receipt by the Company of a written or oral communication from the Commission that the Registration Statement will not be reviewed, or (ii) any registration statement described in Sections 11.1(i) is filed and declared effective but shall thereafter cease to be effective (without being succeeded within ten (10) business days by an effective replacement or amended registration statement) 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 date the Registration Statement is declared effective) or more than 20 consecutive days (each such event referred to in clauses (i) and (ii) of this Section 11.4 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 percent (1%) for each thirty days or part thereof of the Purchase Price of the Shares and actually paid “Purchase Price” (as defined in the Warrants) of Warrant Shares issued or issuable upon actual exercise of the Warrants, for the Registrable Securities owned of record by such holder as of and during the pendency of such Non-Registration Event which are subject to such Non-Registration Event. The Company must pay the liquidated damages in cash within ten (10) days after the end of each thirty (30) day period or shorter part thereof for which liquidated Damages are payable. In the event a Registration Statement is filed by the Filing Date but is withdrawn prior to being declared effective by the Commission, then such Registration Statement will be deemed to have not been filed.

11.5. Expenses. All expenses incurred by the Company in complying with Section 11, including, without limitation, all registration and filing fees, printing expenses, 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, fees of transfer agents and registrars, costs of insurance and fee of one counsel for all Subscribers (in an amount not to exceed $5,000) are called “Registration Expenses.” All underwriting discounts and selling commissions applicable to the sale of Registrable Securities, including any fees and disbursements of any additional counsel to the Subscriber, are called “Selling Expenses.” The Company will pay all Registration Expenses in connection with the registration statement under Section 11. Selling Expenses in connection with each registration statement under Section 11 shall be borne by the Subscriber and may be apportioned among the Subscribers in proportion to the number of shares sold by the Subscriber relative to the number of shares sold under such registration statement or as all Subscribers thereunder may agree.

11.6. Indemnification and Contribution.

(a) In the event of a registration of any Registrable Securities under the 1933 Act pursuant to Section 11, the Company will, to the extent permitted by law, indemnify and hold harmless the Subscriber, each officer of the Subscriber, each director of the Subscriber, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls such Subscriber or underwriter within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which the Subscriber, 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 11, 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 11.6(c),

14

reimburse the Subscriber, each such underwriter and each such controlling person for any reasonable 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 Subscriber 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 Subscriber failed to send or deliver a copy of the final prospectus delivered by the Company to the Subscriber with or prior to the delivery of written confirmation of the sale by the Subscriber 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 such Subscriber, or any such controlling person in writing specifically for use in such registration statement or prospectus.

(b) In the event of a registration of any of the Registrable Securities under the 1933 Act pursuant to Section 11, each Subscriber 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, claims, 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, 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 the registration statement under which such Registrable Securities were registered under the 1933 Act pursuant to Section 11, 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 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 Subscriber will be liable hereunder in any such case if and only 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 made in reliance upon and in conformity with information pertaining to such Subscriber, as such, furnished in writing to the Company by such Subscriber specifically for use in such registration statement or prospectus, and provided, further, however, that the liability of the Subscriber hereunder shall be limited to the net proceeds actually received by the Subscriber 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 11.6(c) and shall only relieve it from any liability which it may have to such indemnified party under this Section 11.6(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 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 11.6(c) for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof

15

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.

(d) In order to provide for just and equitable contribution in the event of joint liability under the 1933 Act in any case in which either (i) a Subscriber, or any controlling person of a Subscriber, makes a claim for indemnification pursuant to this Section 11.6 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 11.6 provides for indemnification in such case, or (ii) contribution under the 1933 Act may be required on the part of the Subscriber or controlling person of the Subscriber in circumstances for which indemnification is not provided under this Section 11.6; then, and in each such case, the Company and the Subscriber will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that the Seller is responsible only for the portion represented by the percentage that the public offering price of its securities offered by the registration statement bears to the public offering price of all securities offered by such registration statement, provided, however, that, in any such case, (y) the Subscriber will not be required to contribute any amount in excess of the public offering price of all such securities offered by it pursuant to such registration statement; and (z) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 10(f) of the 1933 Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

11.7. Delivery of Unlegended Shares.

(a) Within three (3) business days (such third business day, the “Unlegended Shares Delivery Date”) after the business day on which the Company has received (i) a notice that Registrable Securities have been sold either pursuant to the Registration Statement or Rule 144 under the 1933 Act, (ii) a representation that the prospectus delivery requirements, or the requirements of Rule 144, as applicable, have been satisfied, and (iii) the original share certificates representing the shares of Common Stock that have been sold, and (iv) in the case of sales under Rule 144 customary representation letters of the Subscriber and Subscriber’s broker regarding compliance with the requirements of Rule 144, the Company at its expense, (y) shall deliver, and shall cause legal counsel selected by the Company to deliver, to its transfer agent (with copies to the Subscribers requesting such opinion) an appropriate instruction and opinion of such counsel, directing the delivery of shares of Common Stock without any legends including the legends set forth in Sections 4(e) and 4(f) above, issuable pursuant to any effective and current registration statement described in Section 11 of this Agreement or pursuant to Rule 144 under the 1933 Act (the “Unlegended Shares”); and (z) cause the transmission of the certificates representing the Unlegended Shares together with a legended certificate representing the balance of the unsold shares of Common Stock, if any, to the Subscriber at the address specified in the notice of sale, via express courier, by electronic transfer or otherwise on or before the Unlegended Shares Delivery Date. Transfer fees shall be the responsibility of the Subscriber.

(b) In lieu of delivering physical certificates representing the Unlegended Shares, if the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast

16

Automated Securities Transfer program, upon request of a Subscriber, so long as the certificates therefor do not bear a legend and the Subscriber is not obligated to return such certificate for the placement of a legend thereon, the Company shall cause its transfer agent to electronically transmit the Unlegended Shares by crediting the account of Subscriber’s prime Broker with DTC through its Deposit Withdrawal Agent Commission system. Such delivery must be made on or before the Unlegended Shares Delivery Date.

(c) The Company understands that a delay in the delivery of the Unlegended Shares pursuant to Section 11 hereof beyond the Unlegended Shares Delivery Date could result in economic loss to a Subscriber. As compensation to a Subscriber for such loss, the Company agrees to pay late payment fees (as liquidated damages and not as a penalty) to the Subscriber for late delivery of Unlegended Shares in the amount of $100 per business day after the Delivery Date for each $10,000 of purchase price of the Unlegended Shares subject to the delivery default. If during any 360 day period, the Company fails to deliver Unlegended Shares as required by this Section 11.7 for an aggregate of thirty (30) days, then each Subscriber or assignee holding Securities subject to such default may, at its option, require the Company to purchase all or any portion of the Shares and Warrant Shares subject to such default at a price per share equal to 130% of the Purchase Price of such Common Stock and Warrant Shares. The Company shall pay any payments incurred under this Section in immediately available funds upon demand.

(d) In addition to any other rights available to a Subscriber, if the Company fails to deliver to a Subscriber Unlegended Shares as required pursuant to this Agreement, within ten (10) calendar days after the Unlegended Shares Delivery Date and the Subscriber purchases (in an open market transaction or otherwise) shares of common stock to deliver in satisfaction of a sale by such Subscriber of the shares of Common Stock which the Subscriber anticipated receiving from the Company (a “Buy-In”), then the Company shall pay in cash to the Subscriber (in addition to any remedies available to or elected by the Subscriber) the amount by which (A) the Subscriber’s total purchase price (including brokerage commissions, if any) for the shares of common stock so purchased exceeds (B) the aggregate purchase price of the shares of Common Stock delivered to the Company for reissuance as Unlegended Shares, together with interest thereon at a rate of 15% per annum, accruing until such amount and any accrued interest thereon is paid in full (which amount shall be paid as liquidated damages and not as a penalty). For example, if a Subscriber purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to $10,000 of purchase price of shares of Common Stock delivered to the Company for reissuance as Unlegended Shares, the Company shall be required to pay the Subscriber $1,000, plus interest. The Subscriber shall provide the Company written notice indicating the amounts payable to the Subscriber in respect of the Buy-In.

(e) In the event a Subscriber shall request delivery of Unlegended Shares as described in Section 11.7(a), the Company may not refuse to deliver Unlegended Shares based on any claim that such Subscriber or any one associated or affiliated with such Subscriber has been engaged in any violation of law, or for any other reason, unless, an injunction or temporary restraining order from a court, on notice, restraining and or enjoining delivery of such Unlegended Shares or exercise of all or part of said Warrant shall have been sought and obtained and the Company has posted a surety bond for the benefit of such Subscriber in the amount of 130% of the amount of the aggregate purchase price of the Common Stock and Warrant Shares which are subject to the injunction or temporary restraining order, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Subscriber to the extent Subscriber obtains judgment in Subscriber’s favor.

12. (a) Right of First Refusal. During the Exclusion Period, the Subscribers shall be given not less than seven (7) business days prior written notice of any proposed sale by the Company of

17

its common stock or other securities or debt obligations, except in connection with (i) employee stock options or compensation plans, (ii) as full or partial consideration in connection with any merger, consolidation or purchase of substantially all of the securities or assets of any corporation or other entity, or (iii) as has been described in the Reports or Other Written Information filed or delivered prior to the Closing Date (collectively “Excepted Issuances”). The Subscribers who exercise their rights pursuant to this Section 12(a) shall have the right during the seven (7) business days following receipt of the notice to purchase all of such offered common stock, debt or other securities in accordance with the terms and conditions set forth in the notice of sale in the same proportion to each other as their purchase of Shares in the Offering. In the event such terms and conditions are modified during the notice period, the Subscribers shall be given prompt notice of such modification and shall have the right during the original notice period or for a period of seven (7) business days following the notice of modification, whichever is longer, to exercise such right.

(b) Offering Restrictions. Until the Registration Statement is filed, except in connection with the Excepted Issuances or the Offering, the Company will not enter into any agreement to, nor issue any equity, convertible debt or other securities convertible into common stock without the prior written consent of Subscribers holding not less than a majority of the Shares and, if issued, Warrant Shares, which consent may be withheld for any reason.

(c) Maximum Exercise of Rights. In the event the exercise of the rights described in Sections 12(a) would result in the issuance of an amount of common stock of the Company that would exceed the maximum amount that may be issued to a Subscriber calculated in the manner described in Section 10 of the Warrant, then the issuance of such additional shares of common stock of the Company to such Subscriber will be deferred in whole or in part until such time as such Subscriber is able to beneficially own such common stock without exceeding the maximum amount set forth calculated in the manner described in Section 10 of the Warrant. The determination of when such Common Stock may be issued shall be made by each Subscriber as to only such Subscriber.

13. Miscellaneous.
