AGREEMENT

Therefore, the parties hereto hereby agree as follows:

1. Effectiveness; Definitions.

1.1 Closing. This Agreement shall become effective upon the initial purchase of Stock by the Investors in connection with the consummation of the closing under the Acquisition Agreement (the “Closing”).

1.2 Definitions. Certain terms are used in this Agreement as specifically defined herein. These definitions are set forth or referred to in Section 6 hereof.

2. Registration Rights. The Company will perform and comply, and cause each of its subsidiaries to perform and comply, with such of the following provisions as are applicable to it. Each Holder will perform and comply with such of the following provisions as are applicable to such Holder.

2.1 Demand Registration Rights for Investor Registrable Securities.

2.1.1 General. One or more Investors or direct or indirect Permitted Registration Rights Assignees of Investors other than any Financial Investor or direct or indirect Permitted Registration Rights Assignees thereof (the “Initiating Investors”), by notice to the Company specifying the intended method or methods of disposition, may request that the Company effect the registration under the Securities Act for a Public Offering or all or a specified part of the Registrable Securities held by such Initiating Investors; provided, however, that the value of Registrable Securities that the Initiating Investors propose to sell in such Public Offering is at least fifty million dollars ($50,000,000.00) or such lower amount as agreed by the Holders of a majority of the Registrable Securities; and provided, further, that the Initial Public Offering may not be initiated pursuant to this Section 2.1 without the approval of the Holders of a majority of the Registrable Securities. The Company will then use its best efforts to (i) effect the registration under the Securities Act (including by means of a shelf registration pursuant to Rule 415 under the Securities Act if so requested by a majority of the Investors that then hold a number of shares of Common Stock equal to at least $50 million of aggregate Purchase Price Value (in respect of shares originally issued as Common Stock, Preferred Stock or otherwise) and if the Company is then eligible to use such registration) of the Registrable Securities which the Company has been requested to register by such Initiating Investors together with all other Registrable Securities which the Company has been requested to register pursuant to Section 2.2 by other Holders, all to the extent required to permit the disposition (in accordance with the intended methods thereof as aforesaid and as otherwise specified by the Principal Participating Holders) of the Registrable Securities which the Company has been so requested to register, and (ii) if requested by the Principal Participating Holders, obtain acceleration of the effective date of the registration statement relating to such registration; provided, however, that the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 2.1.1:

(a) during the effectiveness of any Principal Lock-Up Agreement entered into in connection with any registration statement pertaining to an underwritten public offering of securities of the Company for its own account (other than a Rule 145 Transaction, or a registration relating solely to employee benefit plans);

(b) upon the request of Initiating Investors that are or were members of an Investor Group on any form other than Form S-3 (or any successor form) if the Company has previously effected a number of registrations of Registrable Securities under this Section 2.1.1 upon the request of Initiating Investors that are or were members of such Investor Group on any form other than Form S-3 (or any successor form) equaling or exceeding three (3) with respect to such Investor Group; provided, however, that any registration of Registrable Securities (i) which does not become and remain effective for at least 270 days in accordance with the provisions of this Section 2 or (ii) pursuant to which the Initiating Investors and all other holders of Registrable Securities joining therein are not able to include at least 90% of the Registrable Securities which they desired to include, shall not be included in the calculation of the numbers of registrations contemplated by this clause (ii); or

-2-

2.1.2 Form. Except as otherwise provided above or required by law, each registration requested pursuant to Section 2.1.1 shall be effected by the filing of a registration statement on Form S-3 (or any other form which includes substantially the same information as would be required to be included in a registration statement on such form as currently constituted); provided, that if any registration requested pursuant to this Section 2.1 is proposed to be effected on Form S-3 (or any successor or similar shortform registration statement) and is in connection with an underwritten offering, and if the managing underwriter shall advise the Company in writing that, in its opinion, it is of material importance to the success of such proposed offering to file a registration statement on Form S-1 (or any successor or similar registration statement) or to include in such registration statement information not required to be included pursuant to Form S-3 (or any successor or similar shortform registration statement), then the Company will file a registration statement on Form S-1 or supplement Form S-3 (or any successor or similar shortform registration statement) as reasonably requested by such managing underwriter.

2.1.3 Payment of Expenses. The Company shall pay all Registration Expenses in connection with registrations of Registrable Securities pursuant to this Section 2.1, including all reasonable expenses (other than fees and disbursements of counsel that do not constitute Registration Expenses) that any Holder incurs in connection with each registration of Registrable Securities requested pursuant to this Section 2.1.

2.1.4 Additional Procedures. In the case of a registration pursuant to Section 2.1 hereof, whenever the Principal Participating Holders shall request that such registration shall be effected pursuant to an underwritten offering, the Company shall include such information in the written notices to Holders referred to in Section 2.2. In such event, the right of any Holder to have securities owned by such Holder included in such registration pursuant to Section 2.1 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed upon by the Principal Participating Holders and such Holder). If requested by the Principal Participating Holders, the Company together with the Holders proposing to distribute their securities through the underwriting will enter into an underwriting agreement with the underwriters for such offering containing such representations and warranties by the Company and such Holders and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including customary indemnity and contribution provisions (subject, in each case, to the limitations on such liabilities set forth in this Agreement).

2.1.5 Suspension of Registration. If the filing, initial effectiveness or continued use of a registration statement, including a shelf registration statement pursuant to Rule 415 under the Securities Act, in respect of a registration pursuant to this Section 2.1, at any time would require the Company to make a public disclosure of material non-public information, which disclosure in the good faith judgment of the Board (after consultation with external legal counsel) (i) would be required to be made in any registration statement so that such registration statement would not be materially misleading, (ii) would not be required to be made at such time but

-3-

for the filing, effectiveness or continue use of such registration statement and (iii) would have a material adverse effect on the Company or its business or on the Company’s ability to effect a material proposed acquisition, disposition, financing, reorganization, recapitalization or similar transaction, then the Company may, upon giving prompt written notice of such action to the Holders participating in such registration, delay the filing or initial effectiveness of, or suspend the use of, such registration statement; provided, that the Company shall not be permitted to do so (i) more than two times during any 12 month period, (ii) for a period exceeding 30 days on any one occasion or (iii) for a period exceeding 60 days in any 12 month period. In the event the Company exercises its rights under the preceding sentence, such Holders agree to suspend, promptly upon their receipt of the notice referred to above, their use of any prospectus relating to such registration in connection with any sale or offer to sell Registrable Securities. The Company shall promptly notify such Holders of the expiration of any period during which it exercised its rights under this Section 2.1.5. The Company agrees that in the event it exercises its rights under this Section 2.1.5, it shall, within 30 days following such Holders’ receipt of the notice of suspension, update the suspended registration statement as may be necessary to permit the Holders to resume use thereof in connection with the offer and sale of their Registrable Securities in accordance with applicable law.

2.2 Piggyback Registration Rights.

2.2.1 Piggyback Registration.

(a) General. Each time the Company proposes to register any shares of Common Stock under the Securities Act on a form which would permit registration of Registrable Securities for sale to the public, for its own account and/or for the account of any other Person (pursuant to Section 2.1 or otherwise) for sale in a Public Offering, the Company will give notice to all Holders of its intention to do so. Any Holder may, be written response delivered to the Company within 20 days after the date of delivery of such notice, request that all or a specified part of such Holder’s Registrable Securities be included in such registration. The Company thereupon will use its best efforts to cause to be included in such registration under the Securities Act all Registrable Securities which the Company has been so requested to register by such Holders, to the extent required to permit the disposition (in accordance with the methods to be used by the Company or, pursuant to Section 2.1, other Holders in such Public Offering) of the Registrable Securities to be so registered; provided, that (i) if, at any time after giving written notice of this intention to register any securities, the Company shall determine for any reason not to proceed with the proposed registration of the securities to be sold by it, the Company may, at its election, give written notice of such determination to each Holder and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith), and (ii) if such registration involves an underwritten offering, all Holders requesting to be included in the Company’s registration must sell their Registrable Securities to the underwriters selected by the Company on the same terms and conditions as apply to the Company (with such differences as may be customary or appropriate in combined primary and secondary offerings) or, in the case of a registration initiated pursuant to Section 2.1.1, the Principal Participating Holders. No registration of Registrable Securities effected under this Section 2.2 shall relieve the Company of any of its obligations to effect registrations of Registrable Securities pursuant to Section 2.1 hereof.

-4-

(b) Excluded Transactions. The Company shall not be obligated to effect any registration of Registrable Securities under this Section 2.2 incidental to the registration of any of its securities in connection with:

(i) Any Public Offering relating to employee benefit plans or dividend reinvestment plans;

(ii) Any Public Offering relating to the acquisition or merger after the date hereof by the Company or any of its subsidiaries of or with any other businesses except to the extent such Public Offering is for the sale of securities for cash; or

(iii) The Initial Public Offering, unless such offering shall have been initiated pursuant to Section 2.1.1 or the Holders of a majority of the Registrable Securities determine otherwise.

2.2.2 Payment of Expenses. The Company will pay all Registration Expenses in connection with registrations of Registrable Securities pursuant to this Section 2.2.

2.2.3 Additional Procedures. Holders participating in any Public Offering pursuant to this Section 2.2 shall take all such actions and execute all such documents and instruments that are reasonably requested by the Company to effect the sale of their Registrable Securities in such Public Offering, including being parties to the underwriting agreement entered into by the Company and any other selling shareholders in connection therewith and being liable in respect of the representations and warranties and the other agreements (including customary selling stockholder representations, warranties, indemnifications and “lock-up” agreements) for the benefit of the underwriters contained therein; provided, however, that (a) with respect to individual representations, warranties, indemnities and agreements of sellers of Registrable Securities in such Public Offering, the aggregate amount of such liability shall not exceed such holder’s net proceeds from such offering and (b) to the extent selling stockholders give further representations, warranties and indemnities, then with respect to all other representations, warranties and indemnities of sellers of shares in such Public Offering, the aggregate amount of such liability shall not exceed the lesser of (i) such holder’s pro rata portion of any such liability, in accordance with such holder’s portion of the total number of Registrable Securities included in the offering, and (ii) such holder’s net proceeds from such offering.

2.2.4 Registration Statement Form. The Company shall select the registration statement form for any registration pursuant to this Section 2.2 (other than a registration that is also pursuant to Section 2.1); provided, that if any registration requested pursuant to this Section 2.2 is proposed to be effected on Form S-3 (or any successor form) and is in connection with an underwritten offering, and if the managing underwriter shall advise the Company in writing that, in its opinion, it is of material importance to the success of such proposed offering to include in such registration statement information not required to be included pursuant to such form, then the Company will supplement such registration statement as reasonably requested by such managing underwriter.

-5-

2.3 Certain Other Provisions.

2.3.1 Underwriter’s Cutback. In connection with any registration of shares, the underwriter may determine that marketing factors (including an adverse effect on the per share offering price) require a limitation of the number of shares to be underwritten. Notwithstanding any contrary provision of this Section 2 and subject to the terms of this Section 2.3.1, the underwriter may limit the number of shares which would otherwise be included in such registration by excluding any or all Registrable Securities from such registration, it being understood that, if the registration in question involves a registration for sale of securities for the Company’s own account, then the number of shares which the Company seeks to have registered in such registration shall not be subject to exclusion, in whole or in part, under this Section 2.3.1. Upon receipt of notice from the underwriter of the need to reduce the number of shares to be included in the registration, the Company shall advise all holders of the Company’s securities that would otherwise be registered and underwritten pursuant hereto, and the number of shares of such securities, including Registrable Securities, that may be included in the registration shall be allocated in the following manner, unless the underwriter shall determine that marketing factors require a different allocation: first, all shares other than Registrable Securities requested to be included in such registration by shareholders other than Holders shall be excluded unless the Company, with the consent of the parties required to approve any amendment or waiver of this Agreement pursuant to Section 5.2, has granted registration rights which are to be treated on an equal basis with Registrable Securities for the purpose of the exercise of the underwriter cutback (such shares afforded such equal treatment being “Parity Shares”); and second, if a further limitation on the number of shares is thereafter required, the number of all Registrable Securities, Parity Shares and other shares of Common Stock that may be included in such registration shall be allocated among the holders thereof in proportion, as nearly as practicable, as follows:

(a) there shall be first allocated to each such holder requesting that its Registrable Securities or Parity Shares be registered in such registration a number of such shares to be included in such registration equal to the lesser of (A) the number of such shares requested to be registered by such holder, and (B) a number of such shares equal to such holder’s Pro Rata Portion;

(b) the balance, if any, not allocated pursuant to clause (a) above shall be allocated to those holders requesting that their Registrable Securities or Parity Shares be registered in such registration which requested to register a number of such shares in excess of such holder’s Pro Rata Portion pro rata to each such holder based upon the number of Registrable Securities and Parity Shares held by such holder, or in such other manner as the holders requesting that their Registrable Securities or Parity Shares be registered in such registration may otherwise agree; and

(c) the balance, if any, not allocated pursuant to clause (b) above shall be allocated to shares, other than Registrable Securities and Parity Shares, requested to be included in such registration by other stockholders.

For purposes of any underwriter cutback, all Registrable Securities held by any Holder shall also include any Registrable Securities held by the partners, retired partners, shareholders or Affiliates of

-6-

such Holder, or the estates and family members of any such Holder or such partners and retired partners, any trusts for the benefit of any of the foregoing Persons and, at the election of such Holder or such partners, retired partners, trusts of Affiliates, any Charitable Organization to which any of the foregoing shall have contributed Common Stock prior to the execution of the underwriting agreement in connection with such underwritten offering, and such Holder and such other Persons shall be deemed to be a single selling Holder, and any pro rata deduction with respect to such selling Holder shall be based upon the aggregate amount of Stock owned by all entities and individuals included in such selling Holder, as defined in this sentence. No securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. Upon delivery of a written request that Registrable Securities be included in the underwriting pursuant to Section 2.1.1 or 2.2.1(a), the Holder thereof may not thereafter elect to withdraw therefrom without the written consent of the Principal Participating Holders; provided, that if the managing underwriter of any underwritten offering shall advise the Holders participating in a registration pursuant to Section 2.1 that the Registrable Securities covered by the registration statement cannot be sold in such offering within a price range acceptable to the Principal Participating Holders, then the Principal Participating Holders shall have the right to notify the Company that they have determined that the registration statement be abandoned or withdrawn, in which event the Company shall abandon or withdraw such registration statement; provided, further that if the price to the public at which the Registrable Securities are proposed to be sold will be less than 90% of the average closing price of the Common Stock during the 10 trading days preceding the date on which notice of such offering was given pursuant to Section 2.2.1(a), then each Investor Group participating in such registration pursuant to Section 2.1 or 2.2 may elect to withdraw from such registration by written notice to the Company. The Company may, but shall not be required to, extend a similar withdrawal right to other Holders of Registrable Securities or Parity Shares.

2.3.2 Registration Procedures. If and in each case when the Company is required to effect a registration of any Registrable Securities as provided in this Section 2, the Company shall promptly:

(a) prepare and, in any event within forty-five days (thirty days in the case of a Form S-3 registration) after the end of the period under Section 2.2.1(a) within which a piggyback request for registration may be given to the Company, file with the Commission a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective within ninety days of the initial filing;

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period not in excess of 270 days (or such shorter period which will terminate when all Registrable Securities covered by such registration statement have been sold) and to comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration statement; provided, that before filing a registration statement or prospectus, or any amendments or supplements thereto in accordance with Sections 2.1 or 2.2, the Company will furnish to counsel selected pursuant to Section 2.3.3 hereof copies of all documents proposed to be filed, which documents will be subject to the review of such counsel;

-7-

(c) furnish to each seller of such Registrable Securities such number of copies of such registration statement and of each amendment and supplement thereto (in each case including all exhibits filed therewith), such number of copies of the prospectus included in such registration statement (including each preliminary prospectus and summary prospectus), in conformity with the requirements of the Securities Act, and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities by such seller;

(d) use its best efforts to register or qualify such Registrable Securities covered by such registration in such jurisdictions as each seller shall reasonably request, and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller, except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction where, but for the requirements of this clause (d), it would not be obligated to be so qualified or to consent to general service of process in any such jurisdiction;

(e) notify each seller of any such Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the Company’s becoming aware that the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and at the request of any such seller, prepare and furnish to such seller a reasonable number of copies of an amended or supplemental prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an 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 in the light of the circumstances then existing;

(f) otherwise use its best efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable (but not more than 18 months) after the effective date of the registration statement, an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act;

(g)(i) use its best efforts to list such Registrable Securities on any securities exchange or authorize for quotation on each other market (including, if applicable, the National Association of Securities Dealers, Inc. (the “NASD”) Automated Quotation System) on which the Common Stock is then listed or authorized for quotation if such Registrable Securities are not already so listed or authorized for quotation; and (ii) use its best efforts to provide a transfer agent and registrar for such Registrable Securities covered by such registration statement not later than the effective date of such registration statement;

(h) enter into such customary agreements (including an underwriting agreement in customary form), which may include indemnification provisions in favor

-8-

of underwriters and other Persons in addition to the provisions of Section 2.4 hereof, and take such other actions as the Principal Participating Holders or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities;

(i) obtain a “cold comfort” letter or letters from the Company’s independent public accountants in customary form and covering matters of the type customarily covered by “cold comfort” letters as the Principal Participating Holders shall reasonably request;

(j) make available for inspection by any seller of such Registrable Securities covered by such registration statement, by any managing underwriter or underwriters participating in any disposition to be effected pursuant to such registration statement and by any attorney, accountant or other agent retained by any such seller or any such managing underwriters), all pertinent financial and other records, pertinent corporate documents and properties of the Company, and cause all of the Company’s officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement (subject to each party referred to in this clause (j) entering into customary confidentiality agreements in a form reasonably acceptable to the Company);

(k) notify counsel (selected pursuant to Section 2.3.3 hereof) for the Holders of Registrable Securities included in such registration statement and the managing underwriter or agent, immediately, and confirm the notice in writing (i) when the registration statement, or any post-effective amendment to the registration statement, shall have become effective, or any supplement to the prospectus or any amendment to the prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request of the Commission to amend the registration statement or amend or supplement the prospectus or for additional information, and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the registration statement for offering or sale in any jurisdiction, or of the institution or threatening of any proceedings for any of such purposes;

(l) make every commercially reasonable effort to prevent the issuance of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus and, if any such order is issued, to obtain the withdrawal of any such order as soon as practicable;

(m) if requested by the managing underwriter or agent or any Holder of Registrable Securities covered by the registration statement, incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or agent or such Holder reasonably requests to be included therein, including, with respect to the number of Registrable Securities being sold by such Holder to such underwriter or agent, the purchase price being paid therefor by such underwriter or agent and with respect to any other terms of the underwritten offering of the Registrable Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters incorporated in such prospectus supplement or post-effective amendment;

-9-

(n) cooperate with the Holders of Registrable Securities covered by the registration statement and the managing underwriter or agent, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such securities to be in such denominations and registered in such names as the managing underwriter or agent, if any, or such Holders may request;

(o) obtain for delivery to the Holders of Registrable Securities being registered and to the underwriter or agent an opinion or opinions from counsel for the Company in customary form and in form, substance and scope reasonably satisfactory to such Holders, underwriters or agents and their counsel;

(p) cooperate with each seller of Registrable Securities and each underwriter or agent participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the NASD; and

2.3.3 Selection of Underwriters and Counsel. The underwriters and legal counsel to be retained by the Company in connection with any Public Offering shall be selected by the Board; provided that, in the case of an offering following a request therefor under Section 2.1.1, such underwriters and counsel shall be reasonably acceptable to the Principal Participating Holders. In connection with any registration of Registrable Securities pursuant to Sections 2.1 and 2.2 hereof, the Principal Participating Holders may select one counsel to represent all Holders of Registrable Securities covered by such registration; provided, however, that in the event that the counsel selected as provided above is also acting as counsel to the Company in connection with such registration, the remaining Holders shall be entitled to select one additional counsel to represent, at such Holders’ expense, all such remaining Holders.

2.3.4 Company Lock-Up. If any registration pursuant to Section 2.1 of this Agreement shall be in connection with an underwritten public offering, the Company agrees not to effect any public sale or distribution of any Common Stock of the Company (or securities convertible into or exchangeable or exercisable for Common Stock) (in each case, other than as part of such underwritten public offering and other than pursuant to a registration on Form S-4 or S-8) for its own account, within 90 days (or such shorter period as the managing underwriters may require) after, the effective date of such registration (except as part of such registration).

2.3.5 Holders and Other Holders Lock-Up. Each Holder and each Other Holder shall comply with the provisions of Section 6 of the Stockholders Agreement applicable to a “Stockholder” as though such Section were set forth herein.

2.3.6 Other Agreements. The Company covenants and agrees that, so long as any Person holds any Registrable Securities in respect of which any registration rights provided for in Section 2.1 of this Agreement remain in effect, the Company will not, directly or indirectly,

-10-

grant to any Person or agree to or otherwise become obligated in respect of (i) rights of registration in the nature or substantially in the nature of those set forth in Section 2.1 of this Agreement that would not be subordinated to the Registrable Securities with respect to the inclusion of such securities in any registration or (ii) demand registration rights exercisable prior to such time as the Investors can first exercise their rights under Section 2.1.

-11-

upon and in conformity with written information furnished to the Company or to any of its subsidiaries through an instrument duly executed by such Covered Person specifically stating that it is for use in the preparation thereof. The indemnities of the Company and of its subsidiaries contained in this Section 2.4.1 shall remain in full force and effect regardless of any investigation made by or on behalf of such Covered Person and shall survive any transfer of securities or any termination of this Agreement.

2.4.2 Indemnities to the Company. Subject to Section 2.4.4, the Company and any of its subsidiaries may require, as a condition to including any securities in any registration statement filed pursuant to this Section 2, that the Company and any of its subsidiaries shall have received an undertaking satisfactory to it from the prospective seller of such securities, severally and not jointly, to indemnify and hold harmless the Company and any of its subsidiaries, each director of the Company or any of its subsidiaries, each officer of the Company or any of its subsidiaries who shall sign such registration statement and each other Person (other than such seller), if any, who controls the Company and any of its subsidiaries within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each other prospective seller of such securities with respect to any statement in or omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus included therein, or any amendment or supplement thereto, or any other disclosure document (including reports and other documents filed under the Exchange Act or any document incorporated therein) or other document or report, if such statement or omission was made in reliance upon and in conformity with written information furnished to the Company or any of its subsidiaries through an instrument executed by such seller specifically stating that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, incorporated document or other document or report. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company, any of its subsidiaries or any such director, officer or controlling Person and shall survive any transfer of securities or any termination of this Agreement.

2.4.3 Contribution. If the indemnification provided for in Sections 2.4.1 or 2.4.2 hereof is unavailable to a party that would have been entitled to indemnification pursuant to the foregoing provisions of this Section 2.4 (an “Indemnitee”) in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each party that would have been an indemnifying party thereunder shall, subject to Section 2.4.4 and in lieu of indemnifying such Indemnitee, contribute to the amount paid or payable by such Indemnitee as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative fault of such indemnifying party on the one hand and such Indemnitee on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof). The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or such Indemnitee and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just or equitable if contribution pursuant to this Section 2.4.3 were determined by pro rata allocation or by any other method of

-12-

allocation which does not take account of the equitable considerations referred to in the preceding sentence. The amount paid or payable by a contributing party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 2.4.3 shall include any legal or other expenses reasonably incurred by such Indemnitee in connection with investigating or defending any such action or claim. 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.

2.4.4 Limitation on Liability of Holders of Registrable Securities. The liability of each Holder of Registrable Securities in respect of any indemnification or contribution obligation of such Holder arising under this Section 2.4 shall not in any event exceed an amount equal to the net proceeds to such Holder (after deduction of all underwriters’ discounts and commissions) from the disposition of the Registrable Securities disposed of by such Holder pursuant to such registration.

2.4.5 Indemnification Procedures. Promptly after receipt by an Indemnitee of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 2.4, such Indemnitee will, 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, that the failure of the Indemnitee to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section 2.4, except to the extent that the indemnifying party is materially prejudiced by such failure to give notice. In case any such action or proceeding is brought against an Indemnitee, the indemnifying party will be entitled to participate in and to assume the defense thereof (at its expense), jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnitee, and after notice from the indemnifying party to such Indemnitee of its election so to assume the defense thereof, the indemnifying party will not be liable to such Indemnitee for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation and shall have no liability for any settlement made by the Indemnitee without the consent of the indemnifying party, such consent not to be unreasonably withheld. Notwithstanding the foregoing, if in such Indemnitee’s reasonable judgment a conflict of interest between such Indemnitee and the indemnifying parties may exist in respect of such action or proceeding or the indemnifying party does not assume the defense of any such action or proceeding within a reasonable time after notice of commencement, the Indemnitee shall have the right to assume or continue its own defense and the indemnifying party shall be liable for any reasonable expenses therefor, but in no event will bear the expenses for more than one firm of counsel for all Indemnitees in each jurisdiction who shall be approved by the Principal Participating Holders in the registration in respect of which such indemnification is sought. No indemnifying party will settle any action or proceeding or consent to the entry of any judgment without the prior written consent of the Indemnitee, unless such settlement or judgment (i) includes as an unconditional term thereof the giving by the claimant or plaintiff of a release to such Indemnitee from all liability in respect of such action or proceeding and (ii) does not involve the imposition of equitable remedies or the imposition of any obligations on such Indemnitee and does not otherwise adversely affect such Indemnitee, other than as a result of the imposition of financial obligations for which such Indemnitee will be indemnified hereunder.

5. Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto.

6. Entire Agreement. The Registration Rights Agreement, as amended by this Amendment Agreement, constitutes the full and entire understanding and agreement among the parties with regard to the subject matter thereof.

7. Severability.
