     2.   Registration Under Securities Act.

2.1   Registration on Request

     (a)   Demand Request. The Shareholder shall have the right, subject to the provisions of the Lock-Up Agreement, to require the Company to effect the registration under the Securities Act of all or part of the Registrable Securities held by the Shareholder, by delivering a written request thereof to the Company specifying the number of shares of Registrable Securities the Shareholder wishes to register (a “Demand Registration”); provided, however, that the aggregate number of the Registrable Securities to be registered pursuant to such Demand Registration constitutes at least two million shares of Common Stock. The Company shall use its reasonable best efforts, including, without limitation, assisting with sales efforts and the selection of appropriate underwriters, to cause the registration statement to become effective in respect of each Demand Registration in accordance with the intended method of distribution set forth in the written request delivered by the Shareholder as expeditiously as possible (but in any event, subject to this Section 2.1, within 120 days of receipt of such written request, and the Company shall file such registration statement within 60 days of receipt of such request).

     (b)   Limitations on Registration on Request. Subject to Section 2.1(a), the Company shall only be required to effect a maximum of three (3) Demand Registrations; provided, however, that the first Demand Request may not be made before the earlier of the (x) termination of the Lock-up Agreement in accordance with its terms or (y) 120 days prior to the second anniversary of the Closing Date, and further, provided, that the Company shall not be required to file (i) more than one such Demand Registration in any twelve-month period or (ii) any such Demand Registration within 120 days following the date of effectiveness of any registration statement relating to a Demand Registration.

     (c)   Registration Statement Form. Demand Registrations under this Section 2.1 shall be on such appropriate registration form of the Commission as selected by the Company.

     (d)   Expenses. Subject to Section 2.1(g), the Shareholder shall pay all Registration Expenses incurred in connection with any registration requested pursuant to this Section 2.1; provided, however, that Shareholder shall not be obligated to pay fees and expenses of counsel to the Company in excess of $50,000 per each Demand Registration.

     (e)   Effective Registration Statement. A Demand Registration requested pursuant to this Section 2.1 shall be deemed to have been effected (including for purposes of paragraph (b) of this Section 2.1) if a registration statement with respect thereto has become effective and has been kept continuously effective for a period of 90 days (or such shorter period which shall terminate when all the Registrable Securities covered by such registration statement have been sold pursuant thereto). A Demand Registration which is not effected, subject to Section 2.1(g), shall not reduce the number of Demand Registrations permitted hereunder.

3

     (f)   Selection of Underwriters. The Managing Underwriters for each underwritten offering of Registrable Securities to be registered pursuant to a Demand Registration shall be a nationally or regionally recognized investment bank that is selected by the Shareholder (subject to the approval by the Company, which approval may not be unreasonably delayed or withheld).

     (g)   Right to Withdraw. If the Managing Underwriters of any underwritten offering shall advise the Company and the Shareholder that the Registrable Securities covered by the registration statement cannot be sold in such offering within a price range acceptable to the Shareholder, then the Shareholder shall have the right to notify the Company in writing that he has determined that the registration statement shall be abandoned or withdrawn, in which event the Company shall abandon or withdraw such registration statement. In the event of any such abandonment or withdrawal, such request shall be counted as a Demand Registration for purposes of the requests for registration to which the Shareholder is entitled pursuant to this Section 2.1.

     (h)   Postponement. The Company shall be entitled once in any twelve-month period to postpone for a reasonable period of time (but not exceeding an aggregate of 60 days, any such period, a “Black-Out Period”) the filing or effectiveness of any registration statement required to be prepared and filed by it pursuant to this Section 2.1 if the Company determines, in its reasonable judgment and based on the advice of its counsel, that such registration and offering would materially interfere with any material financing or other material transaction involving the Company, or if there is an event or state of facts relating to the Company that is material to the Company (and would reasonably likely be required to be disclosed in such registration statement) the disclosure of which would, in the reasonable judgment of the Company, be materially adverse to its interests, and promptly delivers to the Shareholder in such offering a certificate signed by the Company’s chief executive officer or chief financial officer (a “Delay Notice”) stating such determination, containing a general statement of the reasons for such postponement and an estimate of the anticipated delay (but the Company shall not be required to include in such notice any reference to or description of the facts based upon which the Company is delivering such Delay Notice). If the Company shall so postpone the filing of a registration statement, (i) the Company shall use its reasonable best efforts to limit the delay to as short a period as is practicable, and (ii) the Shareholder shall have the right to withdraw the Demand Registration request by giving written notice to the Company within 10 Business Days of receipt of a Delay Notice and, in the event of such withdrawal, such Demand Registration shall not be counted for purposes of requests for Demand Registration to which the Shareholder is entitled pursuant to this Section 2.1. The Company shall be obligated to pay all Registration Expenses in such event.

2.2   Incidental Registration.

     (a)   Right to Include Registrable Securities. If the Company at any time proposes to register any of its common stock for its own account (a “Company Registration”) or the account of any other stockholder under the Securities Act by registration on Form S-1, S-2, or S-3 or any successor or similar form(s) (except registrations on any such form or similar form(s) solely for registration of securities in connection with an employee benefit plan or dividend reinvestment plan or a merger or consolidation or incidental to an issuance of

4

securities under Rule 144A under the Securities Act), it will each such time give prompt written notice to the Shareholder of its intention to do so and of the Shareholder’s rights under this Section 2.2. Upon the written request of the Shareholder (which request shall specify the maximum number of Registrable Securities intended to be disposed of by the Shareholder) made as promptly as practicable and in any event within 10 days after the receipt of any such notice, the Company shall use its reasonable best efforts to effect the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by the Shareholder; provided, however, that in the case of a Company Registration, if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company shall give the Shareholder written notice of such determination and (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from any obligation of the Company to pay its portion of the Registration Expenses in connection therewith), without prejudice, however, to the rights of the Shareholder to request that such registration be effected as a registration under Section 2.1 and (ii) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities, for the same period as the delay in registering such other securities. No registration effected under this Section 2.2 shall relieve the Company of its obligation to effect any registration upon request under Section 2.1. The Shareholder will pay Registration Expenses in proportion to the number of Registrable Securities intended to be disposed of by the Shareholder to the total number of shares of Common Stock included in the Company Registration in connection with any registration of Registrable Securities requested pursuant to this Section 2.2.

     (b)   Right to Withdraw. The Shareholder shall have the right to withdraw its request for inclusion of its Registrable Securities in any registration statement pursuant to this Section 2.2 at any time prior to the execution of an underwriting agreement with respect thereto by giving written notice to the Company of its request to withdraw.

     (c)   Priority in Incidental Registrations. In the case of a Company Registration, if the Managing Underwriters of any underwritten offering shall inform the Company by letter of its belief that the number of Registrable Securities requested to be included in such registration, when added to the number of other securities to be offered by the Company in such registration, would materially adversely affect such offering, then the Company shall include in such registration, to the extent of the number which the Company is so advised can be sold in (or during the time of) such offering without so materially adversely affecting such offering, securities in the following priority: (A) securities proposed to be included by the Company, (B) the Registrable Securities requested by the Shareholder to be included in such registration pursuant to this Section 2.2, and (C) any securities of the Company requested to be included in such registration by any other holder having the right to include securities, on a pro rata basis, based on the number of shares of Common Stock held, or obtainable by exercise or conversion of other securities of the Company, by such holder.

     (d)   Plan of Distribution. Any participation by the Shareholder in a Company Registration shall be in accordance with the Company’s plan of distribution.

5

     (e)   The right of Shareholder to request inclusion of its Registrable Securities in any registration statement pursuant to this Section 2.2 shall terminate immediately if the Lock-up Agreement is terminated in accordance with its terms.

     2.3   Registration Procedures. If and whenever the Company is required, pursuant to the terms of this Agreement, to effect the registration of any Registrable Securities under the Securities Act in accordance with Sections 2.1 or 2.2, the following procedures shall apply:

(a) The Company shall:

(b)   The Company shall give notice to the Shareholder:

6

     (c)   The Company shall use its reasonable best efforts to obtain as soon as possible the withdrawal of any order suspending the effectiveness of the registration statement or the qualification of the securities therein for sale in any jurisdiction.

     (d)   The Company shall promptly deliver to the Shareholder as many copies of the prospectus (including a preliminary prospectus) included in the registration statement and any amendment or supplement thereto as the Shareholder may reasonably request. The Company consents to the use of the prospectus or any amendment or supplement thereto by the Shareholder in connection with the offering and sale of the Registrable Securities pursuant to this Agreement (except during any Black-Out Period).

     (e)   Prior to any offering of Registrable Securities pursuant to a registration statement, the Company shall arrange for the qualification of the Registrable Securities for sale under the laws of such jurisdictions as the Shareholder shall reasonably request and shall maintain such qualification in effect so long as required; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not then so qualified, to consent generally to the service of process in such jurisdiction, or to take any action in connection therewith that would subject it to taxation.

     (f)   Upon the occurrence of any event contemplated by subsections (b)(iii) or (v) above, the Company shall promptly prepare a post-effective amendment to the registration statement or an amendment or supplement to the related prospectus or file any other required document so that the registration statement and the prospectus will not include an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading.

     (g)   The Company shall comply with all applicable rules and regulations of the Commission and shall make generally available to its security holders an earnings statement satisfying the provisions of Section 11(a) of the Securities Act as soon as practicable after the effective date of the registration statement and in any event no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the registration statement.

     (h)   In connection with any underwritten offering effected hereunder, the Company shall:

     The Shareholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in paragraph (b)(iii) or (v) of this Section 2.3, the Shareholder will, to the extent appropriate, discontinue its disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until, in the case of paragraph (b)(v) of this Section 2.3, its receipt of the supplemented or amended prospectus contemplated by paragraph (b)(v) of this Section 2.3 and, if so directed by the Company, will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in its possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. If the disposition by the Shareholder of its securities is discontinued pursuant to the foregoing sentence, the Company shall extend the period of effectiveness of the registration statement by the number of days during the period from and including the date of the giving of notice to and including the date when the Shareholder shall have received copies of the supplemented or amended prospectus contemplated by paragraph (b)(v) of this Section 2.3; and, if the Company shall not so extend such period, the request pursuant to which such registration statement was filed shall not be counted for purposes of the requests for registration to which the Shareholder is entitled pursuant to Section 2.1 hereof.

     It shall be a condition precedent to the obligation of the Company to take any action pursuant to this Agreement in respect of the Registrable Securities which are to be registered at the request of the Shareholder that the Shareholder shall furnish to the Company within ten days of the Company’s request such information regarding the Shareholder and the Registrable Securities held by the Shareholder as the Company shall reasonably request and as shall be required in connection with the action taken by the Company.

2.4   Indemnification and Contribution.

     (a)   Indemnification by the Company. The Company agrees that in the event of any registration of any securities of the Company pursuant to this Agreement, the Company shall, and hereby does, indemnify and hold harmless the Shareholder, and each other Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any, who controls any such underwriter within the meaning of the Securities Act, against any losses, claims, damages, or liabilities, joint or several, to which the Shareholder or any such underwriter or controlling Person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities, joint or several (or actions or proceedings in respect thereof), arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act on the effective date thereof, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto or (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, in light of the circumstances in which they were made) not misleading, and the Company shall reimburse the Shareholder and each such underwriter and controlling Person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding or (iii) any violation by the

9

Company of any federal, state or common law rule or regulation applicable to the Company and relating to action required of or inaction by the Company in connection with any such registration; provided, however, that the Company shall not be liable in any such case to the Shareholder to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company expressly for use in connection with such registration by or on behalf of the Shareholder; provided, further, that as to any preliminary prospectus with respect to an underwritten registration, the provisions of this Section 2.4 shall not inure to the benefit of the Shareholder on account of any loss, claim, damage, liability or action arising from the sale of Common Shares to any person by the Shareholder if the Shareholder failed to send or give a copy of the final prospectus to that person, and the untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact in such preliminary prospectus thereto was corrected in the final prospectus. Such indemnity shall remain in full force regardless of any investigation made by or on behalf of the Shareholder or any such underwriter or controlling Person and shall survive the delivery of and the payment for the Common Shares sold by the Shareholder.

     (b)   Indemnification by the Shareholder. In connection with any registration statement in which the Shareholder includes Registrable Securities the Shareholder hereby agrees to indemnify and hold harmless, severally and not jointly (in the same manner and to the same extent as set forth in paragraph (a) of this Section 2.4), the Company, and each director of the Company, each officer of the Company and each other Person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, but only to the extent such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Shareholder specifically stating that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the delivery of and the payment for the Common Shares sold by the Shareholder.

     (c)   Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding subsections of this Section 2.4, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action or proceeding; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under the preceding subsections of this Section 2.4, except to the extent that the indemnifying party is not otherwise aware of the claim and is actually materially prejudiced by such failure to give notice, and shall not relieve the indemnifying party from any liability which it may have to the indemnified party otherwise than under this Section 2.4. In case any such action or proceeding is brought against an indemnified party, the indemnifying party shall (i)

10

have the right to assume the defense of such action, including the employment of counsel to be chosen by the indemnifying party which is reasonably satisfactory to the indemnified party, and (ii) be responsible for payment of expenses in connection with such action or proceeding. The indemnified party shall have the right to employ its own counsel (including local counsel) in any such case, but the legal fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action, (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to take charge of the defense of such action within a reasonable period of time after notice of the institution of such action, (iii) the indemnified party shall have reasonably concluded that there may be defenses available to it or them that are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), or (iv) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, in any of which events such fees and expenses shall be borne by the indemnifying party. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement that (i) does not include as an unconditional term thereof the giving by the plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation or (ii) provides for relief other than the payment of monetary damages (and such monetary damages shall be paid in full by the indemnifying party).

     (d)   Contribution. If the indemnification provided for in this Section 2.4 shall for any reason be held by a court to be unavailable to an indemnified party under subsection (a) or (b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, then, in lieu of the amount paid or payable under subsection (a) or (b) hereof, the indemnified party and the indemnifying party under subsection (a) or (b) hereof shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating the same), (i) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand, and the indemnified party on the other, which resulted in such loss, claim, damage or liability, or action in respect thereof, with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or if the allocation provided in this clause (ii) provides a greater amount to the indemnified party than clause (i) above, in such proportion as shall be appropriate to reflect not only the relative fault but also the relative benefits received by the indemnifying party and the indemnified party from the offering of the securities covered by such registration statement as well as any other relevant equitable considerations. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 2.4(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the preceding sentence of this Section 2.4(d). No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. In addition, no Person shall be obligated to contribute hereunder any amounts in payment for any settlement of any action or claim effected without such Person’s consent, which consent shall not be unreasonably withheld, conditioned or delayed.

11

     (e)   Other Indemnification. The indemnification agreements contained in this Section 2.4 shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the delivery of and the payment for the Common Shares sold by the Shareholder.

     (f)   Indemnification Payments. The indemnification and contribution required by this Section 2.4 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expenses, losses, damages or liabilities are incurred.

2.5   Stop Transfer Orders. In connection with the offering of any Registrable Securities registered pursuant to this Agreement, the Company shall instruct any transfer agent and registrar of such Registrable Securities to release any stop transfer orders with respect to any such Registrable Securities.

2.6   Limitation on Sale or Distribution of Other Securities.

     (a)   The Shareholder (regardless of whether the Shareholder is participating in such registration) agrees, to the extent requested in writing by a Managing Underwriter of any underwritten registration effected pursuant to and in compliance with Section 2.1 or 2.2, not to sell, transfer or otherwise dispose of, including any sale pursuant to Rule 144 under the Securities Act, any shares of Common Stock, or any other security of the Company convertible into or exchangeable or exercisable for Common Stock (other than as part of such underwritten public offering) during the time period reasonably requested by the Managing Underwriters, not to exceed 90 days and subject to any registration rights to which the Shareholder would otherwise be entitled pursuant to Section 2.2.

     (b)   Notwithstanding the other provisions of this Agreement, the Company shall not be obligated to register the Registrable Securities of the Shareholder (i) if the Shareholder or any underwriter of such Registrable Securities shall fail to furnish to the Company necessary information in respect of the distribution of such Registrable Securities, or (ii) in the case of a Company Registration, if such registration involves an underwritten offering, such Registrable Securities are not included in such underwritten offering on the same terms and conditions as shall be applicable to the other securities of the Company being sold through underwriters in the registration or the Shareholder fails to enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwritten offering.

2.7   No Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of the Shareholder to sell any Registrable Securities pursuant to any effective registration statement.

2.8   Exchange Act Compliance. If the Company is subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Company shall file all reports required to be filed by it under the Exchange Act and it will take such further action as the Shareholder may reasonably request so as to enable the Shareholder to sell Registrable Securities

12

without registration under the Securities Act pursuant to Rule 144 under the Securities Act, as such rule may be in effect from time-to-time, or any similar or successor rule or regulation hereafter promulgated by the Commission.

3.   Miscellaneous.

     3.1   Amendments and Waivers. (i) Any provision of this Agreement may be amended or waived if such amendment or waiver is in writing and signed, in the case of an amendment, by the Company and the Shareholder or, in the case of a waiver, by the party or parties against whom the waiver is to be provided.

(ii)   No failure or delay by any party in exercising any right, power or privilege hereunder (other than a failure or delay beyond a period of time specified herein) shall operate as a waiver thereof and no single or partial exercise thereof shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

     3.2   Notices. Unless otherwise provided herein, any notice, request, instruction or other document to be given hereunder by any party to the other shall be in writing and delivered by hand-delivery, registered first-class mail, telex, telecopier, or air courier guaranteeing overnight delivery, as follows:
