REGISTRATION. a. Mandatory Registration. The Company shall file with the United States Securities and Exchange Commission ("SEC"), on the date which is fourteen (14) calendar days after the Closing Date (the "FILING DEADLINE") a Registration Statement on Form S-3 (or, if Form S-3 is not then available, on such form of Registration Statement as is then available to effect a registration of all of the Registrable Securities, subject to the consent of the Initial Investors as to the use of such form (as determined pursuant to Section 11(j) hereof)) covering the resale of at least 2,956,236 shares of Common Stock, which Registration Statement, to the extent allowable under the Securities Act and the rules promulgated thereunder shall state that such Registration Statement also covers such indeterminate number of additional shares of Common Stock as may become issuable upon exercise of the Warrants to prevent dilution resulting from stock splits, stock dividends or similar transactions (the "INITIAL REGISTRATION STATEMENT"). The Registrable Securities included in the Initial Registration Statement shall be registered on behalf of the Investors as set forth in Section 11(k) hereof. The Initial Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided to (and subject to the review by) the Initial Investors and their counsel at least five (5) business days prior to its filing or other submission. If for any reason (including, but not limited to, a determination by the staff of the SEC that all or any portion of the Warrant Shares or any other Registrable Securities cannot be included in the Initial Registration Statement (an "SEC DETERMINATION")) the Initial Registration Statement declared effective by the SEC does not include all of the Registrable Securities (any such shares that are not included being the "UNCOVERED SHARES"), the Company shall prepare and file with the SEC, as soon as practicable, but in any event prior to the fourteenth (14th) calendar day after becoming -2- 3 aware of the existence of any Uncovered Shares (such date referred to herein as the "UNCOVERED SHARE FILING DEADLINE"), either (a) an amendment (the "UNCOVERED SHARES AMENDMENT") to the Initial Registration Statement effecting a registration of the Uncovered Shares or (b) a registration statement which registers the Uncovered Shares (the "UNCOVERED SHARES REGISTRATION STATEMENT"). The Uncovered Shares Amendment or the Uncovered Shares Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided to the Initial Investors and their counsel for review and comment at least three (3) business days prior to its filing or other submission. The Company shall use all commercially reasonable efforts to cause each of the Initial Registration Statement and the Uncovered Shares Amendment or the Uncovered Shares Registration Statement to become effective as soon as practicable after the filing thereof. b. Underwritten Offering. The Investors may offer and sell the Registrable Securities pursuant to a Registration Statement filed in accordance with Section 2(a) in an underwritten offering. In any such underwritten offering, the Investors who hold a majority in interest of the Registrable Securities subject to such underwritten offering, shall have the right to select one legal counsel to represent the Investors and an investment banker or bankers and manager or managers to administer the offering, which investment banker or bankers or manager or managers shall be reasonably satisfactory to the Company. In the event that any Investors elect not to participate in such underwritten offering, the Registration Statement covering all of the Registrable Securities shall contain appropriate plans of distribution reasonably satisfactory to the Investors participating in such underwritten offering and the Investors electing not to participate in such underwritten offering (including, without limitation, the ability of nonparticipating Investors to sell from time to time and at any time during the effectiveness of such Registration Statement). c. Effectiveness of Registration Statement. The Company shall use reasonable best efforts to cause each Registration Statement required to be filed pursuant to Section 2(a) hereof to become effective as soon as practicable, but, as to the Initial Registration Statement filed pursuant to Section 2(a), in no event later than the ninetieth (90th) day after the Filing Deadline (the "REGISTRATION DEADLINE"), and as to any Uncovered Shares Amendment or Uncovered Shares Registration Statement, in no event later than sixty (60) days after the Uncovered Share Filing Deadline (the "UNCOVERED SHARE REGISTRATION DEADLINE"). d. Eligibility for Form S-3. The Company represents and warrants that it is eligible to register the resale of Registrable Securities on a registration statement on Form S-3 under the Securities Act, and that there exist no facts or circumstances (including without limitation any required approvals or waivers or any circumstances that may delay or prevent the obtaining of accountant's consents) that would prohibit or delay the preparation and filing of a registration statement on Form S-3 with respect to the Registrable Securities. The Company shall file all reports required to be filed by the Company with the SEC in a timely manner so as to maintain or, if applicable, regain its eligibility for the use of Form S-3. -3- 4 3. OBLIGATIONS OF THE COMPANY. In connection with the registration of the Registrable Securities, the Company shall have the following obligations: a. The Company shall prepare and file with the SEC, on or before the Filing Deadline or the Uncovered Share Filing Deadline, as applicable, the applicable Registration Statement required by Section 2(a) and shall use reasonable best efforts to cause such Registration Statement to become effective as soon as practicable after such filing (but in no event later than the Registration Deadline or the Uncovered Share Registration Deadline, as applicable). The Company shall keep such Registration Statement effective pursuant to Rule 415 at all times until the date on which all of the Registrable Securities may (in the reasonable opinion of one counsel identified by the Initial Investors) be immediately sold to the public without registration or restriction pursuant to Rule 144(k) under the Securities Act (the "REGISTRATION PERIOD"). In the event that the sale of Registrable Securities by one or more Investors is determined by the SEC to constitute a primary offering, upon the written request from time to time of any such Investor, the Company shall as promptly as practicable: cause a Registration Statement to be amended and/or one or more additional Registration Statements (which may be requested on a sequential basis) to be filed (as specified by the applicable Investors) and to be declared effective; and take all other actions reasonably requested by such Investors to effectuate the offering of Registrable Securities. If the Initial Registration Statement is not filed on Form S-3, the Company shall, as soon as it is eligible to do so, file a post-effective amendment on Form S-3 to the Initial Registration Statement to the extent permitted by the SEC or, if not so permitted, file a new Registration Statement on Form S-3 to permit sales of the Registrable Securities pursuant to Rule 429 under the Securities Act; and the Company shall use all commercially reasonable efforts to cause such post-effective amendment or Registration Statement to become effective as soon as possible. Each Registration Statement (including any amendments or supplements thereto and prospectuses contained therein and all documents incorporated by reference therein) filed pursuant to this Agreement (i) shall comply in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder and (ii) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading. The financial statements of the Company included in the Registration Statement or incorporated by reference therein will comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC applicable with respect thereto. Such financial statements shall be prepared in accordance with U.S. generally accepted accounting principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed or summary statements) and shall fairly present in all material respects the consolidated financial position of the Company and its consolidated subsidiaries as of the dates thereof and the consolidated results of -4- 5 their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to immaterial year-end adjustments). b. The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to the Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary to keep the Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in the Registration Statement. Notwithstanding the foregoing, the Company's obligations hereunder to file a Registration Statement and to keep a registration statement continuously in effect under the Securities Act shall be suspended if the fulfillment of such obligations would require the Company to make a disclosure that would, in the reasonable judgment of the Company's Board of Directors, have a Material Adverse Effect (as such term is defined in the Securities Purchase Agreement) on the Company or a material adverse effect on the future prospects of the Company or its stockholders; provided, that the Registration Statement shall be suspended for a total of no more than ninety (90) days during any twelve (12) month period. c. The Company shall furnish to each Investor whose Registrable Securities are included in the Registration Statement and its legal counsel (i) promptly after the same is prepared and publicly distributed, filed with the SEC, or received by the Company, one copy of the Registration Statement and any amendment thereto, each preliminary prospectus and prospectus and each amendment or supplement thereto. In the case of the Registration Statement referred to in Section 2(a), the Company shall furnish to each Investor a copy of each letter written by or on behalf of the Company to the SEC or the staff of the SEC (including, without limitation, any request to accelerate the effectiveness of any Registration Statement or amendment thereto), and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion, if any, thereof which contains information for which the Company has sought confidential treatment), (ii) on the date of effectiveness of the Registration Statement or any amendment thereto, a notice stating that the Registration Statement or amendment has been declared effective, and (iii) such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as such Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor. d. The Company shall use all commercially reasonable efforts to (i) register and qualify the Registrable Securities covered by the Registration Statement under such other securities or "blue sky" laws of such jurisdictions in the United States as each Investor who holds Registrable Securities being offered reasonably requests, (ii) prepare and file in those jurisdictions such -5- 6 amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (a) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (b) subject itself to general taxation in any such jurisdiction, (c) file a general consent to service of process in any such jurisdiction, (d) provide any undertakings that cause the Company undue expense or burden, or (e) make any change in its certificate of incorporation or bylaws, which in each case the Board of Directors of the Company determines to be contrary to the best interests of the Company and its stockholders. e. In the event the Investors who hold a majority in interest of the Registrable Securities being offered in an offering select underwriters for the offering, the Company shall enter into and perform its obligations under an underwriting agreement, in usual and customary form, including, without limitation, customary indemnification and contribution obligations, with the underwriters of such offering. f. As promptly as practicable after becoming aware of such event, the Company shall notify each Investor by telephone or facsimile of the happening of any event, of which the Company has knowledge, as a result of which the prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and use reasonable best efforts promptly to prepare a supplement or amendment to the Registration Statement to correct such untrue statement or omission and deliver such number of copies of such supplement or amendment to each Investor as such Investor may reasonably request. g. The Company shall use reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, and, if such an order is issued, to obtain the withdrawal of such order at the earliest practicable date (including in each case by amending or supplementing such Registration Statement) and to notify each Investor who holds Registrable Securities being sold (or, in the event of an underwritten offering, the managing underwriters) of the issuance of such order and the resolution thereof (and if such Registration Statement is supplemented or amended, deliver such number of copies of such supplement or amendment to each Investor as such Investor may reasonably request). h. The Company shall permit a single firm of counsel designated by the Initial Investors to review the Registration Statement and all amendments and supplements thereto a reasonable period of time prior to their filing with the SEC. -6- 7 i.

Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim -10- 11 arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person expressly for use in the Registration Statement or any such amendment thereof or supplement thereto; (ii) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld; and (iii) with respect to any prospectus, shall not inure to the benefit of any Indemnified Person if the untrue statement or omission of material fact contained in such prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented, if such corrected prospectus was timely made available by the Company pursuant to Section 3(c) hereof, and the Indemnified Person was promptly advised in writing not to use the incorrect prospectus prior to the use giving rise to a Violation and such Indemnified Person, notwithstanding such advice, used it. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. b. In connection with any Registration Statement in which an Investor is participating, each such Investor agrees severally and not jointly to indemnify, hold harmless and defend, to the same extent and in the same manner set forth in Section 6(a), the Company, each of its directors, each of its officers who signs the Registration Statement, its employees, agents and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any other stockholder selling securities pursuant to the Registration Statement or any of its directors or officers or any person who controls such stockholder or underwriter within the meaning of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an "INDEMNIFIED PARTY"), against any Claim to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and subject to Section 6(c) such Investor will reimburse any legal or other expenses (promptly as such expenses are incurred and are due and payable) reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor; provided, further, however, that the Investor shall be liable under this Agreement (including this Section 6(b) and Section 7) for only that amount as does not exceed the net proceeds actually received by such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact by the Investor contained in the preliminary prospectus was corrected on a timely basis in the -11- 12 prospectus, as then amended or supplemented, and the Indemnified Party failed to utilize such corrected prospectus. c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action (including any governmental action), such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that such indemnifying party shall not be entitled to assume such defense and an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the reasonable fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential conflicts of interest between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding or the actual or potential defendants in, or targets of, any such action include both the Indemnified Person or the Indemnified Party and the indemnifying party and any such Indemnified Person or Indemnified Party reasonably determines that there may be legal defenses available to such Indemnified Person or Indemnified Party which are in conflict with those available to such indemnifying party. The indemnifying party shall pay for only one separate legal counsel for the Indemnified Persons or the Indemnified Parties, as applicable, and such legal counsel shall be selected by Investors holding a majority-in-interest of the Registrable Securities included in the Registration Statement to which the Claim relates (with the approval of the Initial Investors if any of them holds Registrable Securities included in such Registration Statement), if the Investors are entitled to indemnification hereunder, or by the Company, if the Company is entitled to indemnification hereunder, as applicable. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is actually prejudiced in its ability to defend such action. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable. 7. CONTRIBUTION. To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that (i) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 6, (ii) no person guilty -12- 13 of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation, and (iii) contribution (together with any indemnification or other obligations under this Agreement) by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities. 8. REPORTS UNDER THE EXCHANGE ACT. With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of the Company to the public without registration ("RULE 144"), the Company agrees to: a. file with the SEC in a timely manner and make and keep available all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements (it being understood that nothing herein shall limit the Company's obligations under Section 5(c) of the Securities Purchase Agreement) and the filing and availability of such reports and other documents as is required for the applicable provisions of Rule 144; and b. furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration. 9.

AMENDMENT OF REGISTRATION RIGHTS.
