ARTICLE VIII

LEGENDS

Section 8.1 LEGENDS. (a) Except as otherwise provided below, each certificate representing Registrable Securities will bear the following legend (the “LEGEND”):

The securities represented by this certificate have not been registered under the Securities Act of 1933 (the “Securities Act”) or qualified under applicable state securities laws. These securities may not be offered, sold, pledged, hypothecated, transferred or otherwise disposed of except pursuant to (i) an effective registration statement and qualification in effect with respect thereto under the Securities Act and under any applicable state securities law, (ii) to the extent applicable, Rule 144 under the Securities Act, or (iii) an opinion of counsel reasonably acceptable to the Company that such registration and qualification is not required under applicable federal and state securities laws.”

(b) As soon as practicable after the execution and delivery hereof, the Company shall issue to the Transfer Agent the Transfer Agent Instructions. Such instructions shall be irrevocable by the Company from and after the date thereof or from and after the issuance thereof except as otherwise expressly

provided in the Registration Rights Agreement. It is the intent and purpose of such instructions, as provided therein, to require the Transfer Agent to issue to Investor certificates evidencing shares of Common Stock incident to a Closing, free of the Legend, without consultation by the transfer agent with the Company or its counsel and without the need for any further advice or instruction or documentation to the Transfer Agent by or from the Company or its counsel or Investor; provided that (a) a Registration Statement shall then be effective, (b) Investor confirms to the Transfer Agent and the Company that it has or intends to sell such Common Stock to a third party which is not an affiliate of Investor or the Company and Investor agrees to redeliver the certificate representing such shares of Common Stock to the Transfer Agent to add the Legend in the event the Common Stock is not sold, and (c) Investor confirms to the transfer agent and the Company that Investor has complied with the prospectus delivery requirement under the Securities Act. At any time after the Effective Date, upon surrender of one or more certificates evidencing Common Stock that bear the Legend, to the extent accompanied by a notice requesting the issuance of new certificates free of the Legend to replace those surrendered.

Section 8.2 NO OTHER LEGEND OR STOCK TRANSFER RESTRICTIONS. No legend other than the one specified in Section 8.1 has been or shall be placed on the share certificates representing the Common Stock and no instructions or “stop transfers orders,” so called, “stock transfer restrictions,” or other restrictions have been or shall be given to the Company’s transfer agent with respect thereto other than as expressly set forth in this Article VIII.

Section 8.3 COVER. If the Company fails for any reason to deliver the Put Shares on such Closing Date and the holder of the Put Shares (a “Investor”) purchases, in an open market transaction or otherwise, shares of Common Stock (the “Covering Shares”) in order to make delivery in satisfaction of a sale of Common Stock by such Investor (the “Sold Shares”), which delivery such Investor anticipated to make using the Put Shares (a “Buy-In”), then the Company shall pay to such Investor, in addition to all other amounts contemplated in other provisions of the Transaction Documents, and not in lieu thereof, the Buy-In Adjustment Amount (as defined below). The “Buy-In Adjustment Amount” is the amount equal to the excess, if any, of (x) such Investor’s total purchase price (including brokerage commissions, if any) for the Covering Shares over (y) the net proceeds (after brokerage commissions, if any) received by such Investor from the sale of the Sold Shares. The Company shall pay the Buy-In Adjustment Amount to such Investor in immediately available funds immediately upon demand by such Investor. By way of illustration and not in limitation of the foregoing, if such Investor purchases Covering Shares having a total purchase price (including brokerage commissions) of $11,000 to cover a Buy-In with respect to shares of Common Stock that it sold for net proceeds of $10,000, the Buy-In Adjustment Amount that the Company will be required to pay to such Investor will be $1,000.

Section 8.4 INVESTOR’S COMPLIANCE. Nothing in this Article VIII shall affect in any way Investor’s obligations under any agreement to comply with all applicable securities laws upon resale of the Common Stock.

The Company agrees to indemnify and hold harmless Investor and its officers, directors, employees, and agents, and each Person or entity, if any, who controls Investor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, together with the Controlling Persons (as defined in the Registration Rights Agreement) from and against any Damages, joint or several, and any action in respect thereof to which Investor, its partners, affiliates, officers, directors, employees, and duly authorized agents, and any such Controlling Person becomes subject to, resulting from, arising out of or relating to any misrepresentation, breach of warranty or nonfulfillment of or failure to perform any covenant or agreement on the part of Company contained in this Agreement, as such Damages are incurred, except to the extent such Damages result primarily from Investor’s failure to perform any covenant or agreement contained in this Agreement or Investor’s or its officer’s, director’s, employee’s, agent’s or Controlling Person’s negligence, recklessness or bad faith in performing its obligations under this Agreement.

Section 9.3 METHOD OF ASSERTING INDEMNIFICATION CLAIMS. All claims for indemnification by any Indemnified Party (as defined below) under Section 9.2 shall be asserted and resolved as follows:

(a) In the event any claim or demand in respect of which any person claiming indemnification under any provision of this Article (an “INDEMNIFIED PARTY”) might seek indemnity under this Article is asserted against or sought to be collected from such Indemnified Party by a person other than a party hereto or an affiliate thereof (a “THIRD PARTY CLAIM”), the Indemnified Party shall deliver a written notification, enclosing a copy of all papers served, if any, and specifying the nature of and basis for such Third Party Claim and for the Indemnified Party’s claim for indemnification that is being asserted under any provision of this Article against any person (the “INDEMNIFYING PARTY”), together with the amount or, if not then reasonably ascertainable, the estimated amount, determined in good faith, of such Third Party Claim (a “CLAIM NOTICE”) with reasonable promptness to the Indemnifying Party. If the Indemnified Party fails to provide the Claim Notice with reasonable promptness after the Indemnified Party receives notice of such Third Party Claim, the Indemnifying Party shall not be obligated to indemnify the Indemnified Party with respect to such Third Party Claim to the extent that the Indemnifying Party’s ability to defend has been prejudiced by such failure of the Indemnified Party. The Indemnifying Party shall notify the Indemnified Party as soon as practicable within the period ending thirty (30) calendar days following receipt by the Indemnifying Party of either a Claim Notice or an Indemnity Notice (as defined below) (the “DISPUTE PERIOD”) whether the Indemnifying Party disputes its liability or the amount of its liability to the Indemnified Party under this Article and whether the Indemnifying Party desires, at its sole cost and expense, to defend the Indemnified Party against such Third Party Claim.(i)If the Indemnifying Party notifies the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Indemnified Party with respect to the Third Party Claim pursuant to this Section 9.3(a), then the Indemnifying Party shall have the right to defend, with counsel reasonably satisfactory to the Indemnified Party, at the sole cost and expense of the Indemnifying Party, such Third Party Claim by all appropriate proceedings, which proceedings shall be vigorously and diligently prosecuted by the Indemnifying Party to a final conclusion or will be settled at the discretion of the Indemnifying Party (but only with the consent of the Indemnified Party in the case of any settlement that provides for any relief other than the payment of monetary damages or that provides for the payment of monetary damages as to which the Indemnified Party shall not be indemnified in full pursuant to this Article). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement

thereof; provided, however, that the Indemnified Party may, at the sole cost and expense of the Indemnified Party, at any time prior to the Indemnifying Party’s delivery of the notice referred to in the first sentence of this clause (i), file any motion, answer or other pleadings or take any other action that the Indemnified Party reasonably believes to be necessary or appropriate to protect its interests; and provided further, that if requested by the Indemnifying Party, the Indemnified Party will, at the sole cost and expense of the Indemnifying Party, provide reasonable cooperation to the Indemnifying Party in contesting any Third Party Claim that the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this clause (i), and except as provided in the preceding sentence, the Indemnified Party shall bear its own costs and expenses with respect to such participation. Notwithstanding the foregoing, the Indemnified Party may takeover the control of the defense or settlement of a Third Party Claim at any time if it irrevocably waives its right to indemnity under this Article with respect to such Third Party Claim. (ii) If the Indemnifying Party fails to notify the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Third Party Claim pursuant to Section 9.3(a), or if the Indemnifying Party gives such notice but fails to prosecute vigorously and diligently or settle the Third Party Claim, or if the Indemnifying Party fails to give any notice whatsoever within the Dispute Period, then the Indemnified Party shall have the right to defend, at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings shall be prosecuted by the Indemnified Party in a reasonable manner and in good faith or will be settled at the discretion of the Indemnified Party(with the consent of the Indemnifying Party, which consent will not be unreasonably withheld). The Indemnified Party will have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that if requested by the Indemnified Party, the Indemnifying Party will, at the sole cost and expense of the Indemnifying Party, provide reasonable cooperation to the Indemnified Party and its counsel in contesting any Third Party Claim which the Indemnified Party is contesting. Notwithstanding the foregoing provisions of this clause (ii), if the Indemnifying Party has notified the Indemnified Party within the Dispute Period that the Indemnifying Party disputes its liability or the amount of its liability hereunder to the Indemnified Party with respect to such Third Party Claim and if such dispute is resolved in favor of the Indemnifying Party in the manner provided in clause (iii) below, the Indemnifying Party will not be required to bear the costs and expenses of the Indemnified Party’s defense pursuant to this clause (ii) or of the Indemnifying Party’s participation therein at the Indemnified Party’s request, and the Indemnified Party shall reimburse the Indemnifying Party in full for all reasonable costs and expenses incurred by the Indemnifying Party in connection with such litigation. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this clause (ii), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation. (iii) If the Indemnifying Party notifies the Indemnified Party that it does not dispute its liability or the amount of its liability to the Indemnified Party with respect to the Third Party Claim under this Article or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes its liability or the amount of its liability to the Indemnified Party with respect to such Third Party Claim, the amount of Damages specified in the Claim Notice shall be conclusively deemed a liability of the Indemnifying Party under this Article and the Indemnifying Party shall pay the amount of such Damages to the Indemnified Party on demand. If the Indemnifying Party has timely disputed its liability or the amount of its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute; provided, however, that if the dispute is not resolved within thirty (30) days after the Claim Notice, the Indemnifying Party shall be entitled to institute such legal action as it deems appropriate.

(b) In the event any Indemnified Party should have a claim under this Article against the Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party shall deliver a written

notification of a claim for indemnity under this Article specifying the nature of and basis for such claim, together with the amount or, if not then reasonably ascertainable, the estimated amount, determined in good faith, of such claim (an “INDEMNITY NOTICE”) with reasonable promptness to the Indemnifying Party. The failure by any Indemnified Party to give the Indemnity Notice shall not impair such party’s rights hereunder except to the extent that the Indemnifying Party demonstrates that it has been irreparably prejudiced thereby. If the Indemnifying Party notifies the Indemnified Party that it does not dispute the claim or the amount of the claim described in such Indemnity Notice or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes the claim or the amount of the claim described in such Indemnity Notice, the amount of Damages specified in the Indemnity Notice will be conclusively deemed a liability of the Indemnifying Party under this Article and the Indemnifying Party shall pay the amount of such Damages to the Indemnified Party on demand. If the Indemnifying Party has timely disputed its liability or the amount of its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute; provided, however, that if the dispute is not resolved within thirty (30) days after the Claim Notice, the Indemnifying Party shall be entitled to institute such legal action as it deems appropriate.

(c) The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar rights of the Indemnified Party against the Indemnifying Party or others, and (ii) any liabilities the Indemnifying Party may be subject to.

Section 9.4 REIMBURSEMENT. If (i) any Investor, other than by reason of its gross negligence or willful misconduct, becomes involved in any capacity in any action, proceeding or investigation brought by any stockholder of the Company, in connection with or as a result of the consummation of the transactions contemplated by the Transaction Agreements, or if such Investor is impleaded in any such action, proceeding or investigation by any Person, or (ii) any Investor, other than by reason of its gross negligence or willful misconduct or by reason of its trading of the Common Stock in a manner that is illegal under the federal securities laws, becomes involved in any capacity in any action, proceeding or investigation brought by the SEC against or involving the Company or in connection with or as a result of the consummation of the transactions contemplated by the Transaction Agreements, or if such Investor is impleaded in any such action, proceeding or investigation by any Person, then in any such case, the Company will reimburse such Investor for its reasonable legal and other expenses (including the cost of any investigation and preparation) incurred in connection therewith, as such expenses are incurred. In addition, other than with respect to any matter in which such Investor is a named party, the Company will pay such Investor the charges, as reasonably determined by such Investor, for the time of any officers or employees of such Investor devoted to appearing and preparing to appear as witnesses, assisting in preparation for hearings, trials or pretrial matters, or otherwise with respect to inquiries, hearing, trials, and other proceedings relating to the subject matter of this Agreement. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates of the Investor who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Investor and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Investor and any such Affiliate and any such Person. The Company also agrees that neither any Investor nor any such Affiliate, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any person asserting claims on behalf of or in right of the Company in connection with or as a result of the consummation of the Transaction Agreements except to the extent that any losses, claims, damages, liabilities or expenses incurred by the Company result from the gross negligence or willful misconduct of such Investor.
