Section 1.2 Filing of Registration Statement. Obligation to File Registration Statement. The Company will, within 45 days after the earliest of the Company obtaining stockholder approval of the issuance of Common Stock under the Warrant and Note, obtaining a letter from Nasdaq exempting the Company from obtaining such shareholder approval, or determining that such stockholder approval is not required, file a Registration Statement under the Securities Act covering the sale or other distribution of all or any portion of the Registrable Securities pursuant to Rule 415 under the Securities Act. The Company will use its reasonable efforts to have such Registration Statement declared effective by the SEC as soon as practicable thereafter (the “Effectiveness Deadline”).

(a) Liquidated Damages. To the extent (a) the Registration Statement required pursuant to this Section 1.2 is not filed with the SEC on or prior to the Effectiveness Deadline, (b) such Registration Statement has not been declared effective by the SEC on or prior to the Effectiveness Deadline, or (c) such Registration Statement is filed and declared effective but thereafter ceases to be effective or fails to be usable for its intended purpose without being succeeded within five days by a post-effective amendment thereto that cures such failure and that is itself declared effective within five days of filing such post-effective amendment (each, a “Registration Default”), then the Company will pay to each Holder liquidated damages in an amount equal to one percent (1%) of the original principal amount owed under the Note, for each month or portion thereof that the Registration Default continues. However, in no event shall the Company pay liquidated damages in excess of ten percent (10%) of the principal amount of the Notes in total to each Holder. Any liquidated damages paid hereunder by the Company shall not be considered the charge for or payment of interest under the Notes.

(b) Continuing Agreements. The event of a Registration Default and payment of liquidated damages by the Company will not relieve, impair, adjust, modify or any way change the obligations of the Company under the Loan Documents.

Section 1.3 Piggyback Registrations.

(a) Right to Include Registrable Securities. In the event that a Registration Default has occurred and is continuing, and thereafter the Company from time to time proposes for any reason to register any of its Common Stock under the Securities Act, either for its own account or for the account of a stockholder other than pursuant to a Registration Statement on Forms S-4 or S-8 (or similar or successor forms) or pursuant to one or more secured bridge financing transactions from the Issuance Date of the Note and through the later to occur of the Maturity Date or the date upon which the Note is paid in full (a “Proposed Registration”), the Company will promptly give written notice thereof to all of the Holders (which notice will be given not less than 30 days prior to the expected effective date of the Company’s Registration Statement) and will offer such Holders the right to request inclusion of any of such Holder’s Registrable Securities in the Proposed Registration. No registration pursuant to this Section 1.3 will relieve the Company of its obligation to register Registrable Securities pursuant to Section 1.2, to pay liquidated damages or under the Loan Documents.

3

(b) Piggyback Procedure. Each Holder of Registrable Securities will have 20 days from the date of receipt of the Company’s notice referred to in Section 1.3(a) to deliver to the Company a written request specifying the number of Registrable Securities such Holder intends to sell and such Holder’s intended method of disposition. Any Holder will have the right to withdraw such Holder’s request for inclusion of such holder’s Registrable Securities in any Registration Statement pursuant to this Section 1.3 by giving written notice to the Company of such withdrawal. Subject to Section 1.3(d), the Company will use commercially reasonable efforts to include in such Registration Statement all such Registrable Securities so requested to be included therein; provided, however, that the Company may at any time withdraw or cease proceeding with any such Proposed Registration if it will at the same time withdraw or cease proceeding with the registration of all other shares of Common Stock originally proposed to be registered. If the Proposed Registration by the Company is, in whole or in part, an underwritten public offering of securities of the Company, any request under this Section 1.3(b) will specify that the Registrable Securities be included in the underwriting on the same terms and conditions as the shares, if any, otherwise being sold through underwriters under such registration. If the Company fails to notify Holder or to include Holder’s Registrable Securities in the Proposed Registration as provided in Section 1.3(a) or (b) or the Registrable Securities are excluded under Section 1.3(d), the Company will pay Holder liquidated damages in an amount equal to one percent (1%) of the original principal amount of the indebtedness owed under the Note, for each month or portion thereof that the default continues, subject to the limitations on liquidated damages found in Section 1.2 (a).

(c) Selection of Underwriters. The managing underwriter for any Proposed Registration that involves an underwritten public offering will be one or more reputable nationally recognized investment banks selected by the Company and reasonably acceptable to a majority in interest of the Holders.

(d) Priority for Piggyback Registration. Notwithstanding any other provision of this Article 1, if the managing underwriter of an underwritten public offering determines in good faith and advises the Company and the Holders that the inclusion of all Registrable Securities proposed to be included by the Holders of Registrable Securities in such offering would materially and adversely interfere with the successful marketing of the Company’s securities, then the Holders of Registrable Securities will not be permitted to include any Registrable Securities in excess of the amount, if any, of Registrable Securities which the managing underwriter of such offering will reasonably and in good faith agree in writing to include in such offering in addition to the amount of securities to be registered for the Company. The Company will include in such Registration Statement, as to each Holder, only a portion of the Registrable Securities such Holder has requested be registered equal to the ratio which such Holder’s requested

4

Registrable Securities bears to the total number of Registrable Securities requested to be included in such Registration Statement by all Holders. Pursuant to the foregoing provision, the securities to be included in a registration initiated by the Company will be allocated: (i) first, to the Company; (ii) second, pari passu to the Holders; and (iii) third, to any others requesting registration of securities of the Company.

(b) Indemnification by Holders. In connection with any proposed registration in which a Holder is participating pursuant to this Agreement, each

10

such Holder will furnish to the Company in writing such information with respect to such Holder as the Company may reasonably request or as may be required by law for use in connection with any Registration Statement or prospectus or preliminary prospectus to be used in connection with such registration and each Holder, severally and not jointly, will indemnify and hold harmless the Company, any underwriter retained by the Company and their respective directors, officers, partners, employees, advisors and agents, their respective Affiliates and each Person who controls (within the meaning of the Securities Act or the Exchange Act) any of such Persons to the same extent as the foregoing indemnity from the Company to the Holders as set forth in Section 1.6(a) (subject to the exceptions set forth in the foregoing indemnity, the proviso to this sentence and applicable law), but only with respect to any such information furnished in writing by such Holder expressly for use therein and not with respect to any other Holder or the Company; provided, however, that the liability of any Holder under this Section 1.6(b) will be limited to the amount of the net proceeds received by such Holder in the offering giving rise to such liability.

(c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder (the “Indemnified Party”) will give prompt written notice to the indemnifying party (the “Indemnifying Party”) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to this Agreement; provided, however, that, the failure so to notify the Indemnifying Party will not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party hereunder unless and to the extent such Indemnifying Party is materially prejudiced by such failure. If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party will be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense, with counsel chosen by it and reasonably satisfactory to such Indemnified Party. The Indemnified Party will have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel will be paid by the Indemnified Party unless the Indemnifying Party fails to assume the defense of such action with counsel The Indemnifying Party will not have the right to assume the defense of such action on behalf of such Indemnified Party. No Indemnifying Party will be liable for any settlement entered into without its written consent, which consent will not be unreasonably withheld. No Indemnifying Party will, without the written consent of the Indemnified Party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A)

11

includes an unconditional release of the Indemnified Party from all liability arising out of such action or claim and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any Indemnified Party. The rights afforded to any Indemnified Party hereunder will be in addition to any rights that such Indemnified Party may have at common law, by separate agreement or otherwise.

(d) Contribution. If the indemnification provided for in this Section 1.6 from the Indemnifying Party is unavailable or insufficient to hold harmless an Indemnified Party in respect of any Losses referred to herein, then the Indemnifying Party, in lieu of indemnifying the Indemnified Party, will contribute to the amount paid or payable by the Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the Indemnified Party, as well as any other relevant equitable considerations. The relative faults of the Indemnifying Party and Indemnified Party will be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the Indemnifying Party’s and Indemnified Party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 1.6(d) will be limited to the amount of the net proceeds received by such Holder in the offering giving rise to such liability and the liability of the Company will be limited to an amount as stated in Section 1.6(a). The amount paid or payable by a party as a result of the Losses or other liabilities referred to above will be deemed to include, subject to the limitations set forth in Sections 1.6(a), 1.8(b) and 1.6(c), any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The Parties agree that it would not be just and equitable if contribution pursuant to this Section 1.6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the foregoing. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution pursuant to this Section 1.6(d).

Section 1.7 Rule 144 and Rule 144A; Other Exemptions. With a view to making available to the Holders the benefits of Rule 144 and Rule 144A promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration, the Company covenants that it will (i) file in a timely manner all reports and other documents required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder and (ii) take such further action as each Holder may reasonably request (including, but not limited to, providing any information necessary to comply with Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act), at all times from and after the date hereof all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the

12

limitation of the exemptions provided by (x) Rule 144 and Rule 144A (if available with respect to resales of the Registrable Securities) under the Securities Act, as such rules may be amended from time to time or (y) any other rules or regulations now existing or hereafter adopted by the SEC.

Section 1.8 Certain Limitations On Registration Rights. No Holder may participate in any Registration Statement hereunder unless such Holder completes and executes all questionnaires and other documents reasonably required and will sell such Holder’s Registrable Securities on the basis provided in any underwriting agreement approved by the Holder or Holders entitled hereunder to approve such arrangements. Such Holders of Registrable Securities to be sold by such underwriters may, at their option, require that any or all of the representations and warranties by, and the other agreements on the part of the Company to and for the benefit of such underwriters, will also be made to and for the benefit of such Holders and that any or all of the conditions precedent to the obligations of the underwriters under the underwriting agreement be conditions precedent to the obligations of the Holders.
