(a) From and after the date hereof, the Company shall use its reasonable best efforts to obtain as promptly as practicable any consent or approval of any Person, including any regulatory authority, required in connection with the transactions contemplated hereby.

(b) From and after the date of the Closing, the Company shall use its reasonable best efforts to obtain any vote of stockholders necessary for approval of the Exchange (“Stockholder Approval”). In furtherance of the foregoing statement, the Company shall prepare and use its reasonable best efforts to promptly file with the SEC and to have cleared by the SEC, a preliminary proxy statement, and as soon as practicable thereafter (subject to applicable waiting periods under the Exchange Act, review by the SEC or as required by the Organizational Documents and applicable law) file with the SEC and promptly thereafter mail a definitive proxy statement to the Company’s stockholders (the “Proxy Statement”). The Proxy Statement shall contain the recommendation of the Board, to the extent consistent with its fiduciary duties, that the Company’s stockholders approve the Exchange in accordance with the Organizational Documents and applicable law, including without limitation, the requirements of NASD Rule 4350. The Investor will be given a reasonable opportunity to review and comment on drafts of the Proxy Statement and the Company will use its reasonable best efforts to accept comments thereto given by the Investor and its representatives. The Company shall take all action necessary in accordance with applicable law and its Organizational Documents to convene a meeting of the Company’s stockholders as soon as practicable after the filing of the definitive proxy statement. To the extent consistent with its fiduciary duties, the Company shall use its reasonable best efforts to solicit from the Company’s stockholders proxies in favor of the Exchange and shall take all other action reasonably necessary to secure Stockholder Approval. Notwithstanding the foregoing, the Company shall be deemed to have used its “reasonable best efforts” to secure Stockholder Approval if the Company convenes on or before December 31, 2007 a meeting of its stockholders in accordance with the provisions of this Section 5.5(b) for the purpose of securing Stockholder Approval.

- 23 -

shall have the right to specific performance of such obligations, and if the Investor shall institute any action or proceeding to enforce the provisions hereof, the Company hereby waives the claim or defense that the party instituting such action or proceeding has an adequate remedy at law.

5.6. Use of Proceeds

The proceeds received by the Company from the issuance and sale of the Shares shall be used by the Company for working capital and other general corporate purposes.

5.7. Takeover Statute

If any Takeover Statute shall become applicable to the transactions contemplated hereby, including without limitation any takeover provision under the laws of the State of Delaware, the Company and the members of the Board shall, to the extent consistent with its fiduciary duties, grant such approvals and take such actions as are necessary so that the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and otherwise use their reasonable best efforts to act to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby and the ownership of shares or Exchange Shares by the Investor.

5.8. Tax Covenants

(a) The Investor and the Company agree not to treat the Shares as “preferred stock” within the meaning of Treasury Regulation Section 1.305-5 for United States income tax purposes, and therefore as not subject to section 305 of the Code, and based upon the terms of the Shares as of the Closing Date, the Company shall report dividend income for federal, and any applicable state and local income tax purposes to the Investor solely to the extent that cash dividends are paid on the Shares. Neither the Company nor the Investor shall take any position contrary to the foregoing on any tax return. Notwithstanding the foregoing, neither the Investor nor the Company shall be required to take any action pursuant to this Section 5.8(a) if doing so would be reasonably likely, based upon advice of the Company’s tax advisers, to be unfounded, unlawful or potentially subject the Investor or the Company to a material penalty.

(b) For so long as no Shares have been exchanged, neither the Company nor any Disregarded Entity shall issue any debt security convertible or exchangeable into any capital stock of the Company, which debt security shall have preference or priority over, or be on par with, the Shares without the written consent or affirmative vote of the holders of at least a majority of the then outstanding Shares, given in writing or by vote at a meeting, consenting or voting (as the case may be) separately as a class. For purposes of the preceding sentence, a “Disregarded Entity” shall mean (i) a direct subsidiary of the Company if such subsidiary is treated as a disregarded entity for U.S. federal income tax purposes, and (ii) an indirect subsidiary of the Company provided that (a) such subsidiary is treated as a disregarded entity for U.S. federal income tax purposes and (b) such subsidiary is owned by an entity treated as a disregarded entity for U.S. federal income tax purposes. In addition for so long as no Shares have been exchanged, the Company shall not make any distribution on any class of stock (other than the Exchangeable Preferred Stock or Common Stock) which in the opinion of both the Investor’s tax advisors and the Company’s tax advisors would result in any non-cash distribution

- 24 -

or accumulation on the Shares being currently taxable under Section 305(b)(2) of the Code; provided, however, that if the Investor’s tax advisors and the Company’s tax advisors disagree as to whether such distribution would result in any non-cash distribution or accumulation on the Shares being currently taxable under Section 305(b)(2) of the Code, the Investor and the Company shall appoint a nationally known, independent tax advisor mutually acceptable to the Investor and the Company who shall render an opinion as to whether such distribution would result in any non-cash distribution or accumulation on the Shares being currently taxable under Section 305(b)(2) of the Code, which opinion shall be binding on the Investor and the Company. The fees of the independent tax advisor shall be borne 50% by the Investor and 50% by the Company.

SECTION 8. COVENANTS

8.1. Management Rights

Following the Closing, the Investor will be entitled to certain contractual management rights, in addition to any rights to non-public financial information, inspection rights, and other rights expressly agreed to be provided to the Investor pursuant to the Agreement and any other transaction documents, which such management rights shall include the following:

(a) The right to be consulted with and express its views as to the management of the Company on significant business issues, including management’s proposed annual operating plans, and to meet with management during each year at the Company’s facilities at mutually agreeable times for such purposes and to review progress in achieving said plans.

(b) The right to examine the books and records of the Company and inspect its facilities and request information at reasonable times and intervals concerning the general status of the Company’s financial condition and operations.

- 28 -

(c) The right to assign and/or transfer the rights set forth in this Section 8.1 to any other investor advised or managed by Warburg Pincus LLC.

(d) The right, if the Investor Designee is not a member of the Board, to have a representative of the Investor attend all meetings of its Board, in a nonvoting observer capacity and, in this respect, the Company shall give such representative copies of all notices, minutes, consents, and other materials that it provides to its directors, except that the representative may be excluded from access to any material or meeting or portion thereof if the Company believes, upon advice of counsel, that such exclusion is reasonably necessary to preserve the attorney-client privilege, to protect highly confidential proprietary information or for other similar reasons. Such representative may participate in discussions of matters brought to the Board.

The rights set forth in this Section 8.1 are intended to satisfy the requirement of management rights for purposes of qualifying the Investor’s investments in the Company as “venture capital investments” for purposes of the Department of Labor “plan assets” regulation, 29 C.F.R. §2510.3-101. In the event the aforementioned rights are not satisfactory for such purpose, the Company and the Investor shall reasonably cooperate in good faith to agree upon mutually satisfactory management rights that satisfy such regulations. The rights described in this Section 8.1 shall terminate and be of no further force or effect upon the date on which the Investor does not Own, either directly or indirectly, any interest in or capital stock of the Company

8.2. Confidentiality

As to so much of the information and other material furnished under or in connection with this Agreement (including without limitation information furnished pursuant to Section 8.1 hereof), or under or in connection with the Confidentiality Agreement, as constitutes or contains confidential business, financial or other information of the Company, the Investor covenants for itself and its members and officers that it will not disclose such confidential information and will use due care to prevent its officers, employees, agents, advisors and other representatives from disclosing such information to Persons other than their authorized stockholders, owners, partners, directors, managers, officers, members, employees, agents, counsel, accountants, advisors and other authorized representatives or from using such information except as Investor or for the benefit of the Company. Should the Investor be advised by its counsel that such disclosure or delivery is required by law, regulation or judicial or administrative order, to the extent reasonably practicable, the Investor shall give the Company prior notice of the request or requirement so that the Company may seek a protective order or other appropriate remedy; provided, however, that in the absence of such protective order, the Investor or any of its representatives may disclose or deliver any information or other material disclosed to or received by it upon the advice of counsel provided the Investor exercises reasonable efforts at the Company’s expense, to protect the confidentiality of the information. It being understood that the Investor makes investments in the ordinary course of business in various Persons and, as a result of such investments, such Persons may be deemed to be affiliated or associated with the Investor, and to the extent that the Investor does not make such information available to such Persons, this Section 8.2 shall not apply to such Persons. The Investor shall use reasonable care to ensure proper secure storage for the confidential information and other material furnished in connection with this Agreement to protect such

- 29 -

information from unauthorized access and to promptly inform the Company if the Investor becomes aware that any confidential information has been disclosed to an unauthorized person and to take reasonable steps to retrieve such information and protect it from further disclosure. The investor agrees to be responsible for any breach of this Section 8.2 by its officers, employees, agents, advisors and other representatives due to the disclosure of such information to Persons other than their authorized stockholders, owners, partners, directors, managers, officers, members, employees, agents, counsel, accountants, advisors and other authorized representatives. For purposes of this Section 8.2, “reasonable care” means at least a reasonably comparable level of care that the Investor would use to protect the confidentiality of its own sensitive or proprietary information, and this obligation shall survive termination of this Agreement. In the event of any termination of this Agreement prior to the Closing Date, the Investor shall return to the Company or destroy all confidential material furnished to the Investor or its officers, members, employees, agents, counsel, accountants, advisors and other authorized representatives in connection with this transaction except that the Director and such Persons may retain a copy of such confidential material if required by law, regulation or internal compliance procedures.

8.3. Lost, etc. Certificates Evidencing Shares; Exchange

Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any certificate evidencing any Shares or Exchange Shares owned by the Investor, and (in the case of loss, theft or destruction) of an unsecured indemnity satisfactory to it, and upon reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of such certificate, if mutilated, the Company will make and deliver in lieu of such certificate a new certificate of like tenor and for the number of securities evidenced by such certificate which remain outstanding. The Investor’s agreement of indemnity shall constitute indemnity satisfactory to the Company for purposes of this Section 8.3. Upon surrender of any certificate representing any Shares or Exchange Shares, for exchange at the office of the Company, the Company at its expense will cause to be issued in exchange therefor new certificates in such denomination or denominations as may be requested for the same aggregate number of Shares or Exchange Shares represented by the certificate so surrendered and registered as such holder may request. The Company will also pay the cost of all deliveries of certificates for such Shares or Exchange Shares to the office of the Investor (including the cost of insurance against loss or theft in an amount satisfactory to the holders) upon any exchange provided for in this Section 8.3.

8.4. Securities Law Disclosure; Publicity

The Company shall, at or prior to 8:30 a.m., Eastern Time, on the first day following the date of this Agreement on which trading occurs on the NASDAQ Stock Market, (i) issue a press release reasonably acceptable to the Investor disclosing the transactions contemplated hereby. No later than the fourth Business Day after the signing of this Agreement, the Company shall file a Current Report on Form 8-K with the SEC (the “8-K Filing”) describing the transactions contemplated hereby, in the form required by the Exchange Act. The Company shall file this Agreement as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2007 or if it so chooses, as an exhibit to the 8-K Filing. Thereafter, the Company shall timely file any filings and notices required by the SEC or the NASD with

- 30 -

respect to the transactions contemplated hereby. Notwithstanding the foregoing, the Company shall not name the Investor in any press release in any statement made with the intent of widespread pubic dissemination without prior notice to the Investor, except to the extent such press release or disclosure is required by law, SEC regulations or forms, NASD regulations or as set forth in the form of press release attached here to as Exhibit H, in which case the Company shall provide the Investor with prior notice of such disclosure. In furtherance of the foregoing, but not in limitation thereof, the parties acknowledge and agree that the Company shall be able to name the Investor in any private conference or presentation and to respond to questions (even in public conferences or presentation) regarding the Investor, based on information already in the public domain.

8.5. HSR Act Filing

The Company and the Investor shall (a) as soon as practicable after the date of this Agreement, but in no event later than 20 days following the Closing Date, file Notification and Report Forms under the HSR Act with the FTC relating to the transaction contemplated by this Agreement, (b) use their reasonable best efforts to respond as promptly as practicable to all inquiries received from the FTC for additional information or documentation and (c) request that the waiting period under the HSR Act be terminated early.

8.6. Insurance

The Company will use its reasonable efforts to maintain insurance, including without limitation directors and officers insurance, with responsible and reputable insurance companies or associations in such amounts and covering such risks as the Company determines is reasonably adequate for the conduct of its business and the value of its property. For purposes of clarity, the parties acknowledge and agree that the Company shall not be required to expand its insurance coverage beyond those risk areas insured by the Company as of the date hereof and that the Company shall not be required to maintain its current level of insurance coverage with respect to any area of risk if the Board has determined that such level is no longer necessary or appropriate.
