ARTICLE II

Registration Rights

Section 2.01 Demand Registrations.

(a) Requests for Registration. At any time after the Registration Period Commencement Date, subject to the conditions set forth herein, Wellspring shall be entitled to make a written request of the Company (a “Demand”) for registration under the Securities Act of all or part of its Registrable Securities (a “Demand Registration”). Such Demand shall specify: (i) the aggregate number of Registrable Securities requested to be registered; and (ii) the intended method of distribution in connection with such Demand Registration to the extent then known.

(b) Number of Demands. Wellspring shall be entitled to a total of four (4) Demand Registrations.

(c) Satisfaction of Obligations. Subject to the provisions of Section 2.03, a registration shall not be treated as a permitted Demand for a Demand Registration until (i) the applicable registration statement under the Securities Act has been filed with the Commission with respect to such Demand Registration (which shall include any registration statement that is not withdrawn by holders of Registrable Securities in the circumstances contemplated by Section 2.03); and (ii) such registration statement shall have been maintained continuously effective for a period of at least one hundred eighty (180) days or such shorter period during which all Registrable Securities included therein have been disposed of thereunder in accordance with the method of distribution set forth in such registration statement; provided, however, that if Wellspring withdraws a Demand after the registration statement with respect thereto has been filed with the Commission, such registration statement will nevertheless be treated as a permitted Demand for a Demand Registration unless Wellspring pays to the Company all of the expenses of such registration, in which event such registration statement shall not be treated as a permitted Demand for a Demand Registration.

(d) Availability of Short Form Registrations. The Company shall use its commercially reasonable efforts to comply with the requirements for use of short form registration for the sale of Registrable Securities under the Securities Act.

(e) Restrictions on Demand Registrations. The Company shall not be obligated (i) to maintain the effectiveness of a registration statement under the Securities Act for a period longer than 180 days; or (ii) to effect any Demand Registration within one hundred eighty (180) days of the effective date of (A) a

4

registration in which Wellspring was given “piggyback” rights pursuant to Section 2.02 hereof (provided that, with respect to such a registration in which such piggyback rights were exercised, Wellspring was permitted to include in such registration 100% of the Registrable Securities that Wellspring sought to include therein) or (B) any other Demand Registration, In addition, the Company shall be entitled to postpone (upon written notice to Wellspring) for up to ninety (90) days the filing or the effectiveness of a registration statement in respect of a Demand (but no more than once in any period of twelve (12) consecutive months) if the Board determines in good faith and in its reasonable judgment that effecting the Demand Registration in respect of such Demand would have a material adverse effect on any proposal or plan by the Company to engage in any debt or equity offering, material acquisition or disposition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer, or other similar transaction or otherwise would be materially detrimental to the Company. In the event of a postponement by the Company of the filing or effectiveness of a registration statement in respect of a Demand, Wellspring shall have the right to withdraw such Demand in accordance with Section 2.03 hereof.

(f) Participation in Demand Registrations. Except with the prior written consent of Wellspring III, the Company may not include any securities to be sold for the Company’s account in a Demand Registration other than a Piggyback Registration by HBK under Section 2.02 which shall not require Wellspring’s consent. If, in connection with a Demand Registration, any managing underwriter advises the Company and Wellspring that, in its opinion, the inclusion of all the Registrable Securities and, if authorized pursuant to this Article II, other securities of the Company sought to be registered in connection with such Demand Registration would adversely affect the marketability of the Registrable Securities sought to be sold pursuant thereto, then the Company shall include in the registration statement applicable to such Demand Registration only such securities as the Company and Wellspring are advised by such underwriter can be sold without such an effect (the “Maximum Demand Number”), as follows and in the following order of priority:

(i) first, the number of Registrable Securities sought to be registered by Wellspring pursuant to such Demand and the number of Registrable Securities sought to be registered by HBK pursuant to Section 2.02; provided, however, that, in the event that the aggregate number of Registrable Securities to be sold pursuant to this clause (i) exceeds the Maximum Demand Number, then the number of Registrable Securities to be registered by each of Wellspring and HBK shall be reduced pro rata such that the total number of Registrable Securities to be registered equals the Maximum Demand Number; and

(ii) second, if the number of Registrable Securities to be included under clause (i) above is less than the Maximum Demand Number, the number of securities sought to be included by the Company and each other seller, pro rata in proportion to the number of securities sought to be sold by the Company and all such other sellers, which in the aggregate, when added to the number of securities to be included pursuant to clause (i) above, equals the Maximum Demand Number.

5

(g) Selection of Underwriters. If Wellspring requests that such Demand Registration be an underwritten offering, then Wellspring shall be entitled to select a nationally recognized underwriter or underwriters to manage and administer such offering.

(h) Other Registrations. If the Company has received a Demand and if the applicable registration statement in respect of such Demand has not been withdrawn or abandoned, the Company shall not file or cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable into or exercisable for its equity securities under the Securities Act (other than a registration relating to the Company’s employee benefit plans, exchange offers by the Company, or a merger or acquisition of a business or assets by the Company, including, without limitation, a registration on Form S-8 or S-4 or any successor form), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least ninety (90) days has elapsed from the effective date of any Demand Registration, unless a shorter period of time is approved by Wellspring. Notwithstanding the foregoing, the Company shall be entitled to postpone any such Demand Registration and may file or cause to be effected such other registration in accordance with the terms of Section 2.01(e) hereof.

Section 2.02 Piggyback Registrations.

(a) Right to Piggyback. At any time after the Registration Period Commencement Date, whenever the Company proposes to register any shares of its Common Stock or Common Stock held by any stockholders of the Company under the Securities Act (other than a registration under Regulation A or relating to the Company’s employee benefit plans, exchange offers by the Company, or a merger or acquisition of a business or assets by the Company, including, without limitation, a registration on Form S-8 or Form S-4 or any successor form) (a “Piggyback Registration”), the Company shall give each of the Shareholders prompt written notice thereof (but not less than ten (10) business days prior to the filing by the Company with the Commission of any registration statement with respect thereto). Such notice (a “Piggyback Notice”) shall specify the number of securities proposed to be registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution and the proposed managing underwriter or underwriters (if any and if known). Upon the written request of a Shareholder given to the Secretary of the Company within five (5) business days of the receipt by such Shareholder of the Piggyback Notice requesting that the Company include in such registration Registrable Securities owned by such Shareholder (which written request shall specify the number of Registrable Securities intended to be disposed of by such Shareholder and the intended method of distribution thereof), the Company shall include in such registration all Registrable Securities with respect to which the Company has received such written requests for inclusion, in accordance with the terms hereof. Notwithstanding anything to the contrary contained herein, if Wellspring includes any of its or its affiliates securities in any Public Offering (including a Qualified Initial Public Offering), HBK will be permitted to include its securities in such Public Offering as a Piggyback Registration under Section 2.02.

6

(b) Priority on Piggyback Registrations. If, in connection with a Piggyback Registration (other than a Demand Registration which is governed by Section 2.01), any managing underwriter (or, if such Piggyback Registration is not an underwritten offering, a nationally recognized independent underwriter selected by the Company) advises the Company and the holders of the Registrable Securities to be included in such Piggyback Registration, that, in its opinion, the inclusion of all the securities sought to be included in such Piggyback Registration by the Company, and by the Shareholders seeking to sell such securities in such Piggyback Registration (“Piggyback Sellers”), in each case, if any would adversely affect the marketability of the securities sought to be sold pursuant thereto, then the Company shall include in the registration statement applicable to such Piggyback Registration only such securities as the Company and the Piggyback Sellers are so advised by such underwriter can be sold without such an effect (the “Maximum Piggyback Number”), as follows and in the following order of priority:

(i) first, such number of securities sought to be registered by the to be registered be the Company, up to the Maximum Piggyback Number;

(ii) second, if the number of securities to be included under clause (i) above is less than the Maximum Piggyback Number, then such number of Registrable Securities sought to be registered by the Piggyback Seller pursuant to a Piggyback Registration; provided, however, that, in the event that the aggregate amount of Registrable Securities to be registered pursuant to this clause (ii) and clause (i) above exceeds the Maximum Piggyback Number, then the number of Registrable Securities to be included in such Piggyback Registration by each Piggyback Seller shall be reduced pro rata such that the total number of securities to be registered equals the Maximum Piggyback Number; and

(iii) third, if the number of securities to be included under clauses (i) and (ii) above is less than the Maximum Piggyback Number, pro rata in proportion to the securities sought to be registered by all other sellers which, in the aggregate, when added to the number of securities to be registered under clauses (i) and (ii) above, equals the Maximum Piggyback Number.

(c) Withdrawal by the Company. If, at any time after giving written notice of its intention to register any of its securities as set forth in this Section 2.02 and prior to the time the registration statement filed in connection with such registration is declared effective, the Company shall determine for any reason not to register such securities, the Company may, at its election, give written notice of such determination to each Shareholder and thereupon shall be relieved of its obligation to

7

register any Registrable Securities in connection with such particular withdrawn or abandoned registration; provided, however, that notwithstanding Sections 2.06 and 3.06, the Company shall reimburse each Shareholder for all of its out-of-pocket costs and expenses (including reasonable attorneys fees) incurred in connection with such registration.

Section 2.03 Withdrawal Rights. Any Shareholder having notified or directed the Company to include any or all of its Registrable Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities designated for registration thereby by giving written notice to such effect to the Company, In the event of any such withdrawal, the Company shall not include such Registrable Securities in the applicable registration and such Registrable Securities shall continue to be Registrable Securities hereunder. Subject to Section 2.01(c) such withdrawal shall not affect the obligations of the Company with respect to the Registrable Securities not so withdrawn.

Section 2.04 Holdback Agreements. Each Shareholder agrees not to effect any public sale or distribution (including, without limitation, sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the ten (10) day period prior to the date on which the Company intends to commence a Public Offering (provided the Shareholders are notified in writing of such commencement date) through the ninety (90) day period immediately following the effective date of any such Public Offering (except as part of such registration), or, if later, the 90 day period immediately following the execution date of any underwriting agreement with respect thereto.

Section 2.05 Registration Procedures.

(a) Whenever the Shareholders have requested that any Registrable Securities be registered pursuant to this Agreement, the Company (subject to its right to withdraw such registration as contemplated by Section 2.02(c)) shall use commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof and, in connection therewith, the Company shall:

(i) use commercially reasonable efforts to (A) register the Registrable Securities on Form S-3 or another available short form registration statement, to the extent permitted under the Securities Act, (B) cause the registration statement to remain effective for a continuous period of not less than 180 days (or, if earlier, until all of the Registrable Securities included in such registration statement have been sold thereunder), subject to Section 2.05(c), and (C) obtain the withdrawal of any order suspending the registration or qualification (or the effectiveness thereof) or suspending or preventing the use of any related prospectus in any jurisdiction with respect thereto;

8

(ii) promptly notify each seller of Registrable Securities of each of (A) the filing and effectiveness of the registration statement and prospectus and any amendment or supplements thereto, (B) the receipt of any comments from the Commission or any state securities law authorities or any other governmental authorities with respect to any such registration statement or prospectus or any amendments or supplements thereto, and (C) any oral or written stop order with respect to such registration, any suspension of the registration or qualification of the sale of such Registrable Securities in any jurisdiction, or any initiation or threatening of any proceedings with respect to any of the foregoing;

(iii) furnish to each seller of Registrable Securities, the underwriters, and the sales or placement agent, if any, and counsel for each of the foregoing, a conformed copy of such registration statement and each amendment and supplement thereto (in each case, including all exhibits thereto and documents incorporated by reference therein) and such additional number of copies of such registration statement, each amendment, and supplement thereto (in such case without such exhibits and documents), the prospectus (including each preliminary prospectus) included in such registration statement, and prospectus supplements and all exhibits thereto and documents incorporated by reference therein, and such other documents as such seller, underwriter, agent, or counsel may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(iv) use commercially reasonable efforts to register or qualify such Registrable Securities under such securities or “blue sky” laws of such jurisdictions as the holders of Registrable Securities reasonably request and do any and all other acts and things that may be reasonably necessary or advisable to enable the holders of Registrable Securities to consummate the disposition in such jurisdictions of the Registrable Securities owned by such holders and keep such registration or qualification in effect for so long as the registration statement remains effective under the Securities Act (provided that the Company shall not be required to (x) qualify generally to do business in any jurisdiction in which it would not otherwise be required to qualify but for this paragraph, (y) subject itself to taxation in any such jurisdiction in which it would not otherwise be subject to taxation but for this paragraph or (z) consent to the general service of process in any jurisdiction in which it would not otherwise be subject to general service of process but for this paragraph);

(v) notify each seller of such Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, upon the discovery that, or of the happening of any event as a result of which, the registration statement covering such Registrable Securities, as then in effect, contains an untrue statement of a material fact or omits to state any material fact required to be stated

9

therein or any fact necessary to make the statements therein not misleading, and promptly prepare and furnish to each such seller a supplement or amendment to the prospectus contained in such registration statement so that such Registration Statement shall not, and such prospectus as thereafter delivered to the purchasers of such Registrable Securities shall not, contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or any fact necessary to make the statements therein not misleading;

(vi) use commercially reasonable efforts to cause all such Registrable Securities to be listed on any securities exchange or established over-the-counter market on which or through which similar securities of the Company are listed or traded and, if not so listed or traded, to be listed on the NASD automated quotation system (“Nasdaq”) and, if listed on Nasdaq, use commercially reasonable efforts to secure designation of all such Registrable Securities covered by such registration statement as a Nasdaq “national market system security” within the meaning of Rule HAa2-l under the Exchange Act; or, failing that, to secure Nasdaq authorization for such Registrable Securities;

(vii) make available for inspection by any seller of Registrable Securities and any attorney, accountant, or other agent retained by any such seller or underwriter all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, attorneys, and independent accountants to supply all information reasonably requested by any such sellers, attorneys, accountants, or agents in connection with such registration statement. Information that the Company determines, in good faith, to be confidential shall not be disclosed by such persons unless (x) the disclosure of such information is necessary to avoid or correct a misstatement or omission in such registration statement, or (y) the release of such information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction. Each seller of Registrable Securities agrees, on its own behalf and on behalf of all its accountants, attorneys, and agents, that the information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company unless and until such is made generally available to the public. Each seller of Registrable Securities further agrees, on its own behalf and on behalf of all its accountants, attorneys, and agents, that it will, upon learning that disclosure of such information is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of the information deemed confidential;

(ix) permit any Shareholder, which Shareholder, in its sole and exclusive judgment, might be deemed to be an underwriter or controlling person of the Company, to participate in the preparation of such registration statement and to require the insertion therein of material, furnished to the Company in writing, that in the reasonable judgment of such holder and such holder’s counsel should be included.

(b) Underwriting. Without limiting any of the foregoing, in the event that the offering of Registrable Securities is to be made by or through an underwriter, the Company shall enter into an underwriting agreement with a managing underwriter or underwriters containing representations, warranties, indemnities, and agreements customarily included (but not inconsistent with the agreements contained herein) by an issuer of common stock in underwriting agreements with respect to offerings of common stock for the account of, or on behalf of, such issuers, In connection with the sale of Registrable Securities hereunder, any seller of such Registrable Securities may, at its option, require that any and all conditions precedent to the obligations of such underwriter or underwriters (or which would be so for the benefit of such underwriter or underwriters under a customary underwriting agreement) be conditions precedent to the obligations of such seller in connection with the disposition of its securities pursuant to the terms hereof. In connection with any offering of Registrable Securities registered pursuant to this Agreement, the Company shall (x) furnish to the underwriter, if any (or, if no underwriter, the sellers of such Registrable Securities), unlegended certificates representing ownership of the Registrable Securities being sold, in such denominations as requested and (y) instruct any transfer agent and registrar of the Registrable Securities to release any stop transfer order with respect thereto.

(c) Return of Prospectuses. Each seller of Registrable Securities hereunder agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.05(a)(v), such seller shall forthwith discontinue such seller’s disposition of Registrable Securities pursuant to the applicable registration statement and prospectus relating thereto until such seller’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.05(a)(v) and, if so directed by the Company, deliver to the Company all copies, other than permanent file copies, then in such seller’s possession of the prospectus current at the time of receipt of such notice relating to such Registrable Securities. In the event the Company shall give such notice, the one hundred and eighty (180) day period during which such registration statement must remain effective pursuant to Section 2.05(a)(i) of this Agreement (or such shorter period as permitted by Section 2.05(a)(i)) shall be extended by the number of days during the period from the date of giving of a notice

11

regarding the happening of an event of the kind described in Section 2.05(a)(v) to the date when all such sellers shall receive such a supplemented or amended prospectus and such prospectus shall have been filed with the Commission.

Section 2.06 Registration Expenses. All expenses incident to the Company’s performance of, or compliance with, its obligations under this Agreement including, without limitation, all registration and filing fees, all fees and expenses of compliance with securities and “blue sky” laws (including, without limitation, the fees and expenses of counsel for underwriters or placement or sales agents in connection therewith), all printing and copying expenses, all messenger and delivery expenses, all fees and expenses of underwriters and sales and placement agents in connection therewith (excluding discounts and commissions of such underwriters or placement agents), all fees and expenses of the Company’s independent certified public accountants and counsel (including, without limitation, with respect to “comfort” letters and opinions) (collectively, the “Registration Expenses”) shall be borne by the Company; provided, however, that notwithstanding the foregoing, (i) all underwriting discounts and commissions allocable to each Shareholder selling Registrable Securities shall be borne by such Shareholder and (ii) the Company shall not be responsible for the fees and expenses of any additional counsel, or any of the accountants, agents, or experts retained by the Shareholders in connection with the sale of Registrable Securities. The Company will pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties, the expense of any annual audit, and the expense of any liability insurance) and the expenses and fees for listing the securities to be registered on each securities exchange and included in each established over-the-counter market on which similar securities issued by the Company are then listed or traded or for listing on Nasdaq.

Section 2.07 Indemnification.

(a) By the Company. The Company agrees to indemnify, to the fullest extent permitted by law, each holder of Registrable Securities being sold, its directors, and each Person who controls (within the meaning of the Securities Act) such holder against all losses, claims, damages, liabilities, and expenses (including legal fees and expenses and all costs incident to investigation or preparation with respect to such losses, claims, damages, liabilities, and expenses and to reimburse such indemnified Person for such costs as incurred) (collectively, the “Losses”) caused by, resulting from, or relating to any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus, or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or a fact necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished to the Company by or on behalf of such holder expressly for use therein or by such holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same and notified such holder of such obligation.

12

(b) By the Shareholders. In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder will, if requested, furnish to the Company in writing information regarding such holder’s ownership of Registrable Securities and, to the extent permitted by law, shall indemnify the Company, its directors, and each Person who controls (within the meaning of the Securities Act) the Company against all Losses caused by, resulting from, or relating to any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus, or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is caused by and contained in such information furnished in writing to the Company by or on behalf of such holder. The liability of the Shareholders will be limited to the proceeds received by such Shareholder from the sale of its Registrable Securities pursuant to such registration statement.

(c) Notice. Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to which its seeks indemnification; provided, however, the failure to give such notice shall not release the indemnifying party from its obligation, except to the extent that the indemnifying party has been materially prejudiced by such failure to provide such notice.

(d) Defense of Actions. In any case in which any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel selected by the indemnifying party and reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not (so long as it shall continue to have the right to defend, contest, litigate, and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expense incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, supervision and monitoring (unless such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it that are different from or in addition to the defenses available to such indemnifying party, in which event the indemnified party shall be reimbursed by the indemnifying party for the expenses incurred in connection with retaining separate legal counsel). An indemnifying party shall not be liable for any settlement of an action or claim effected without its prior written consent. The indemnifying party shall lose its right to defend, contest, litigate, and settle a matter if it shall fail diligently to contest such matter (except to the extent settled in accordance with the next following sentence). No matter to which an indemnified party is entitled to indemnity hereunder shall be settled by an indemnifying party (unless such settlement only involves the payment of money and does not include any other relief) without the consent of the indemnified party (which consent shall not be unreasonably withheld).

13

(e) Survival. The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person and will survive the transfer of the Registrable Securities and the termination of this Agreement.

(f) Contribution. If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or reasons. In determining the amount of contribution to which the respective Persons are entitled, there shall be considered the Persons’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby agreed that it would not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita allocation. No person guilty of fraudulent misrepresentation (within the meaning of Section 1l(f) of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation. Notwithstanding the foregoing, no Shareholder shall be required to make a contribution in excess of the net amount received by such holder from the sale of Registrable Securities. The liability of the Shareholders will be limited to the proceeds received by such Shareholder from the sale of its Registrable Securities pursuant to such registration statement.
