As of the date of this Agreement, the Company is eligible to file the Registration Statement on Form S-3. (2) Prior to the SEC Effective Date or during any time subsequent to the SEC Effective Date when the Registration Statement for any reason is not available for use by any Purchaser for the resale of any Registrable Securities hereunder, the Company shall not file any other registration statement or any amendment thereto with the SEC under the 1933 Act or request the acceleration of the effectiveness of any other registration statement previously filed with the SEC, other than any registration statement registering securities issued (v) to 3 <PAGE> holders of registration rights described in Schedule 11(a), (w) pursuant to compensation plans for employees, directors, officers, advisers or consultants of the Company and in accordance with the terms of such plans, (x) upon exercise of conversion, exchange, purchase or similar rights issued, granted or given by the Company and outstanding as of the date of this Agreement and disclosed in the SEC Reports or the Subscription Agreement, (y) pursuant to a public offering underwritten on a firm commitment basis registered under the 1933 Act or (z) as part of a transaction involving a strategic alliance, acquisition of stock or assets, merger, collaboration, joint venture, partnership or other similar arrangement of the Company with another corporation, partnership or other business entity (A) which is engaged in a business similar, complementary or related to the business of the Company or (B) pursuant to which the Company issues securities with the primary purpose to directly or indirectly acquire, license or otherwise become entitled to use technology relevant to or useful in the Company's business, so long as in each case of this clause (z) the Board of Directors of the Company by resolution duly adopted (and a copy of which shall be furnished to the Purchaser promptly after adoption) duly approves such transaction in accordance with its duties under applicable law (each of the forgoing transactions a "BOARD APPROVED TRANSACTION"). (b) CERTAIN OFFERINGS. If any offering pursuant to a Registration Statement pursuant to Section 2(d) hereof involves an underwritten offering, Purchasers who hold a majority in interest of the Registrable Securities (including for this purpose the Securities convertible into or exercisable for such Registrable Securities) subject to such underwritten offering shall have the right to select one legal counsel. The Purchasers who hold the Registrable Securities (including for this purpose the Securities convertible into or exercisable for such Registrable Securities) to be included in such underwriting shall pay all underwriting discounts and commissions and other fees and expenses of any investment banker or bankers and manager or managers (other than fees and expenses relating to registration of Registrable Securities under federal or state securities laws, which are payable by the Company pursuant to Section 5 hereof) with respect to such Registrable Securities and the fees and expenses of such legal counsel so selected by the Purchasers. (c) CERTAIN PAYMENTS. So long as any Securities or Registrable Securities remain outstanding, if an Event (as defined below) shall occur, then (x) on each of the first month anniversary of the Event Date, the second month anniversary of the Event Date and the third month anniversary of the Event Date, unless and until the applicable Event is cured, the Company shall pay in cash to each Purchaser a default payment at the rate of 1.5% per month of the purchase price paid by such Purchaser pursuant to the Subscription Agreement and (y) on the fourth month anniversary of the Event Date and each monthly anniversary thereafter, unless and until the applicable Event is cured, the Company shall pay in cash to each Purchaser a default payment at the rate of 2.0% per month of the purchase price paid by such Purchaser pursuant to the Subscription Agreement (collectively, the "DELAY PAYMENTS"). The Delay Payments pursuant to the terms hereof shall apply on a pro-rata basis for any portion of a month prior to the cure of an Event. By way of example, if an Event is cured 15 days after the Event Date, the Company shall owe an amount to each Purchaser equal to such Purchaser's purchase price multiplied by 1.5% multiplied by 15 divided by 30. If the Company fails to pay any Delay Payments pursuant to this Section in full within seven (7) days after the date payable, the Company will pay interest on such Delay Payments at a rate of 12% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Purchaser, accruing daily 4 <PAGE> from the date such Delay Payments are due until such amounts, plus all such interest thereon, are paid in full. The Delay Payments shall not preclude the Purchaser from seeking appropriate additional damages and remedies for any such Events. Each of the following failures or breaches shall constitute an "EVENT": (i) the initial Registration Statement is not filed on or prior to the 30th day following the Closing Date (if the Company files such Registration Statement without affording the Purchaser the opportunity to review and comment on the same as required by Section 3(h) hereof, subject to the Company's obligation under Regulation FD under the 1934 Act, the Company shall be deemed not to have satisfied this clause (i)); (ii) the initial Registration Statement filed hereunder is not declared effective by the Commission on or prior to the later of (A) the 75th day following the Closing Date (provided that the Company shall have filed a notice of acceleration with the SEC within five Trading Days of its receipt of notification that the SEC does not plan to review the Registration Statement) and (B) in the event of an SEC review of the Registration Statement, the 150th day following the Closing Date (the "EFFECTIVENESS REQUIRED DATE"); (iii) after a Registration Statement is filed with and declared effective by the SEC, such Registration Statement ceases to be effective as to a material portion of the Registrable Securities at any time prior to the expiration of the Registration Period without being succeeded within twenty (20) Trading Days by an amendment to such Registration Statement or by a subsequent Registration Statement filed with and declared effective by the SEC, (iv) the Common Stock shall be delisted or suspended from trading on the Nasdaq National Market or on any exchange or other principal market for the Common Stock (other than a general suspension of trading on such market) for more than ten (10) consecutive Trading Days; (v) the exercise rights of the Warrantholders pursuant to the Warrants or the conversion rights of the holders of Preferred Shares pursuant to the Preferred Shares are suspended or not complied with by the Company in accordance with the terms of the Warrants and/or the Preferred Shares due to a breach by the Company of its obligations under any of the Transaction Documents (as defined in the Subscription Agreement), and such suspension or non-compliance shall continue uncured for a period of 5 Trading Days after notice thereof is given by any such Purchaser to the Company; (vi) an amendment to a Registration Statement is not filed by the Company with the SEC within twenty (20) Trading Days of the SEC's notifying the Company that such amendment is required in order for such Registration Statement to be declared effective; or (vii) after a Registration Statement is filed with and declared effective by the SEC, any Purchaser is unable to sell Registrable Securities for any reason under the Registration Statement for more than fifteen (15) Trading Days or an aggregate of thirty (30) 5 <PAGE> Trading Days in a 12-month period after notice of any such inability is given by any such Purchaser to the Company. For purposes of clause (i), the date upon which such thirty (30) day period is exceeded, for purposes of clause (ii), the date upon which such 75th day or 150th day (as applicable) is exceeded, for purposes of clause (iii) and (vi), the date upon which such twenty (20) Trading Day period is exceeded, for purposes of clause (iv), the date upon which such ten (10) Trading Day period is exceeded, for purposes of clause (v), the date upon which such five (5) Trading Day period is exceeded, or for purposes of clause (vii) the date on which such fifteen (15) Trading Day period or thirty (30) Trading Day period (as applicable) is exceeded, is hereby referred to as the "EVENT DATE"). (d) PIGGY-BACK REGISTRATIONS. If at any time the Company shall determine to prepare and file with the SEC a registration statement relating to an offering for its own account or the account of others under the 1933 Act of any of its equity securities, other than a registration statement registering securities issued (1) pursuant to compensation plans for employees, directors, officers, advisers or consultants of the Company and in accordance with the terms of such plans or (2) as part of a Board Approved Transaction, the Company shall send to each Purchaser who is entitled to registration rights under this Agreement written notice of such determination and, if within five (5) Trading Days after receipt of such notice, a Purchaser shall so request in writing, the Company shall include in such Registration Statement all or any part of the Registrable Securities the Purchaser requests to be registered, except that if, in connection with any underwritten public offering for the account of the Company, the managing underwriter(s) thereof shall impose a limitation on the number of shares of Common Stock which may be included in the Registration Statement because, in such underwriter(s)' judgment, such limitation is necessary to effect an orderly public distribution, then the Company shall be obligated to include in such Registration Statement only such limited portion of the Registrable Securities with respect to which the Purchaser has requested inclusion hereunder. Any exclusion of Registrable Securities shall be made pro rata among the Purchasers seeking to include Registrable Securities, in proportion to the number of Registrable Securities sought to be included by such Purchasers; provided, however, that the Company shall not exclude any Registrable Securities unless the Company has first excluded all outstanding securities the holders of which are not entitled by right to inclusion of securities in such Registration Statement; and provided further, however, that, after giving effect to the immediately preceding proviso, any exclusion of Registrable Securities shall be made pro rata with holders of other securities having the right to include such securities in the Registration Statement, based on the number of securities for which registration is requested except to the extent such pro rata exclusion of such other securities is prohibited under any written agreement entered into by the Company with the holder of such other securities prior to the date of this Agreement, in which case such other securities shall be excluded, if at all, in accordance with the terms of such agreement. No right to registration of Registrable Securities under this Section 2(d) shall be construed to limit any registration required under Section 2(a) hereof. The obligations of the Company under this Section 2(d) may be waived as to all Purchasers by the Majority Holders and as to a particular Purchaser by such Purchaser and shall expire after the Company has afforded the opportunity for each Purchaser to exercise registration rights under this Section 2(d) for two registrations; provided, however, that any Purchaser who shall have had any Registrable 6 <PAGE> Securities excluded from any Registration Statement in accordance with this Section 2(d) shall be entitled to include in an additional Registration Statement filed by the Company the Registrable Securities so excluded. Notwithstanding any other provision of this Agreement, if the Registration Statement required to be filed pursuant to Section 2(a) of this Agreement shall have been ordered effective by the SEC and the Company shall have maintained the effectiveness of such Registration Statement as required by this Agreement and if the Company shall otherwise have complied in all material respects with its obligations under this Agreement, then the Company shall not be obligated to register any Registrable Securities on such Registration Statement referred to in this Section 2(d).

INDEMNIFICATION. In the event any Registrable Securities are included in a Registration Statement under this Agreement: (a) To the extent permitted by law, the Company will indemnify and hold harmless each Purchaser, the directors, officers and partners, if any, of such Purchaser, each person, if any, who controls any Purchaser within the meaning of the 1933 Act or the 1934 Act, any underwriter (as defined in the 1933 Act) for the Purchasers, the directors, officers and partners, if any, of such underwriter, and each person, if any, who controls any such underwriter within the meaning of the 1933 Act or the 1934 Act, against any losses, claims, damages, liabilities or expenses (joint or several) incurred (collectively, "CLAIMS") to which any of them may become subject under the 1933 Act, the 1934 Act or otherwise, insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any of the following: (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any post-effective amendment thereof or 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, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the 12 <PAGE> statements made therein, in light of the circumstances under which the statements therein were made, not misleading or (iii) any violation or alleged violation by the Company of the 1933 Act, the 1934 Act, any state securities law or any rule or regulation under the 1933 Act, the 1934 Act or any state securities law (the matters in the foregoing clauses (i) through (iii) being, collectively, "VIOLATIONS"). Subject to the restrictions set forth in Section 6(d) with respect to the number of legal counsel, the Company shall reimburse the Purchasers and the other persons indemnified under this Section 6(a), promptly as such expenses are incurred and are due payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (I) shall not apply to a Claim 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 any indemnified person under this Section 6(a) or expressly for use in connection with the preparation of the Registration Statement, the prospectus or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 3(c) hereof; (II) with respect to any preliminary prospectus shall not inure to the benefit of any indemnified person under this Section 6(a) if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected in the prospectus, as then amended or supplemented, if such prospectus was timely made available by the Company pursuant to Section 3(c) hereof; and (III) 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. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified person referred to in this Section 6(a) and shall survive the transfer of the Registrable Securities by the Purchasers pursuant to Section 9. (b) In connection with any Registration Statement in which a Purchaser is participating, each such Purchaser agrees to indemnify and hold harmless, to the same extent and in the same manner set forth in Section 6(a), the Company, each of its directors, officers and partners who signs the Registration Statement, each person, if any, who controls the Company within the meaning of the 1933 Act or the 1934 Act, any underwriter and any other stockholder selling securities pursuant to the Registration Statement or any of its directors, officers, partners or any person who controls such stockholder or underwriter within the meaning of the 1933 Act or the 1934 Act, against any Claim to which any of them may become subject, under the 1933 Act, the 1934 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 Purchaser expressly for use in connection with such Registration Statement or any post-effective amendment thereof, or any prospectus included therein; and such Purchaser will reimburse any legal or other expenses reasonably incurred by any indemnified person under this Section 6(b), promptly as such expenses are incurred and are due and payable, 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 Purchaser, which consent shall not be unreasonably withheld; provided, further, however, that each Purchaser shall be liable under this Section 6(b) for only that amount of a Claim as does not exceed the amount of the proceeds to such Purchaser from the sale of the Registrable Securities pursuant to such Registration Statement that resulted in such Claim. Such indemnity shall remain in full force and 13 <PAGE> effect regardless of any investigation made by or on behalf of any indemnified person under this Section 6(b) and shall survive the transfer of the Registrable Securities by the Purchasers 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 person under this Section 6(b) if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented. (c) The Company shall be entitled to receive indemnities from underwriters, selling brokers, dealer managers and similar securities industry professionals participating in any distribution, to the same extent as provided above, with respect to information so furnished in writing by such persons expressly for inclusion in the Registration Statement. (d) Each party entitled to indemnification under this Section 6 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any such Claim as to which indemnity may be sought and the Indemnifying Party shall have the right to participate in, and, to the extent the Indemnifying Party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel selected by the Indemnifying Party but reasonably acceptable to the Indemnified Party; provided, however, that an Indemnified Party shall have the right to retain its own counsel with the 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 Party and the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceeding. In such event, the Company shall pay for only one separate legal counsel for the Purchasers; such legal counsel shall be selected by the Purchasers holding a majority in interest of the Registrable Securities (including for this purpose the Securities exercisable for or convertible into such Registrable Securities) included in the Registration Statement to which the Claim relates. 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 Party under this Section 6, except to the extent that the Indemnifying Party is 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 (a) 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, (b) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation and (c) contribution by any Purchaser shall be limited in amount to the amount by which the net amount of proceeds received by such Purchaser (if any) from the sale of such 14 <PAGE> Registrable Securities that resulted in such Claim exceeds the purchase price paid by such Purchaser for such Registrable Securities. 8. REPORTS UNDER 1934 ACT. With a view to making available to the Purchasers the benefits of Rule 144, the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144; (b) file with the SEC in a timely manner all reports and other documents required of the Company under the 1933 Act and the 1934 Act; and (c) furnish to each Purchaser so long as such Purchaser owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144 and the 1934 Act or describing any failure to so comply, (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 Purchasers to sell such securities pursuant to Rule 144 without registration. 9. ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the Company register Registrable Securities pursuant to this Agreement shall be automatically assigned by the Purchasers to any Permitted Transferee only if: (a) the Purchaser agrees in writing with such Permitted Transferee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (b) except as otherwise provided in the Subscription Agreement, the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (i) the name and address of such Permitted Transferee and (ii) the securities with respect to which such registration rights are being transferred or assigned, (c) immediately following such transfer or assignment the further disposition of such securities by such Permitted Transferee is restricted under the 1933 Act and applicable state securities laws, and (d) at or before the time the Company receives the written notice contemplated by clause (b) of this sentence (or such later time within ten Business Days after the Company approves a Permitted Transferee pursuant to the Subscription Agreement), such Permitted Transferee agrees in writing with the Company to be bound by all of the provisions contained herein and in the Subscription Agreement. In connection with any such transfer the Company shall, at the cost and expense of the Permitted Transferee, promptly after such assignment take such actions as shall be reasonably acceptable to the Initial Purchaser and such Permitted Transferee to assure that the Registration Statement and related prospectus are available for use by such Permitted Transferee for sales of the Registrable Securities in respect of which the rights to registration have been so assigned; provided, however, that the Company shall not be required to breach any other obligation hereunder in taking such actions. In connection with any such assignment, each Purchaser shall have the right to assign to such Permitted Transferee such Purchaser's rights under the Subscription Agreement by notice of such assignment to the Company. Following such notice of assignment of rights under the Subscription Agreement, the Company shall be obligated to such Permitted Transferee to perform all of its covenants under the Subscription Agreement as if such Permitted Transferee were the Buyer under the Subscription Agreement. 15 <PAGE> 10. AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Agreement may be amended only with the written consent of the Majority Holders and the Company and, subject to the penultimate sentence of Section 2(d), the observance by the Company of any provision of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Majority Holders.

(c) A person or entity is deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities.
