Your resignation shall be effective regardless of the continued effectiveness of this letter agreement. From and after the Resignation Date, your obligations to the Company and the Company's obligations to you shall be solely those provided for in this letter agreement, inclusive of the exhibits attached hereto.

2. Cooperation in Transition. For the period from March 22, 2006 through June 21, 2006 (the "Retirement Date"), you shall remain an employee of the Company (the period from March 22, 2006 through June 21, 2006 to be referenced as the "Transition Period"), subject at all times to the policies, procedures and requirements of the Company, and shall make yourself available upon reasonable request by the Company, and at mutually agreeable times, during the Transition Period to assist in transitioning your former responsibilities to the person or persons designated by the Company to receive them, including but not limited to by providing the Company with the location of, and access information for, all computers and other electronic, recording and storage devices, and any other media containing electronic or physical versions copies of Company property, documents, records, files, emails and information. In this regard, you agree that you will generally provide assistance to the Company during the Transition Period telephonically or electronically and will present yourself at mutually agreed upon times at the Company or such other mutually agreeable location during the Transition Period only at the request of the Company on an as-needed basis; provided, however, that you will be present as necessary during the period from March 22, 2006 through April 5, 2006 to assist with the BBG transaction (or such shorter period as the Company determines in its discretion), and provided further that you shall have no further involvement with any other CRA business activities or transactions, unless such involvement (including but not limited to conference calls and other communications) includes a designated Company representative in all instances, and any such communications confirm that you have no authority to bind the Company. Notwithstanding any of the foregoing, you shall have no authority during the Transition Period to act on behalf of the Company and shall not do so, shall make no public representations on behalf of the Company, and shall incur no expenses on behalf of the Company unless specifically authorized.

Employee understands that any agreements relating to the non-solicitation and nonhiring of persons affiliated with the Company entered into by and between Employee and the Company remain in full force and effect.

5. Non-Competition

In addition to and without limiting the foregoing, during the course of Employee's employment and for a period of one (1) year following Employee's termination of employment and/or association with the Company for any reason (collectively and hereinafter the "Restriction Period"), Employee agrees that Employee, directly or indirectly, shall not, whether as owner, partner, shareholder, director, consultant, agent, employee, guarantor, surety or otherwise, or through any person, consult with, associate or in any way aid, deal or assist any competitor of the Company or engage or attempt to engage in any employment, consulting or other activity, which competes, directly or indirectly, with the Business of the Company anywhere in the Restricted Territory. For purposes of this Agreement, the Restricted Territory shall be wherever the Company has provided services to its clients and ultimate clients (as defined below) in the two (2) years preceding' the Restriction Period, which includes any country where the services were performed or delivered and in the geographic area where the Company has formulated written plans to open an office to provide its services. For purposes of this Agreement, the term "employment" shall include the employment of Employee as an employee, consultant, agent, independent contractor or otherwise. For purposes of this Agreement, the Company's "Business" is services, which combine economic and financial analysis with expertise in litigation and regulation support, business strategy and planning, market and demand forecasting, policy analysis, engineering and technology management, and also includes advising on economic, valuation and strategy issues related to intellectual property and commercial disputes.

Employee acknowledges that Employee's participation in the conduct of any such Business alone or with any person other than the Company will materially impair the business, goodwill and prospects of the Company.

Employee further agrees that for one (1) year after Employee's employment with the Company ends for any reason, Employee will not, individually, on behalf of or in concert with others, solicit, call on or accept work from direct clients and/or ultimate clients with whom Employee had contact while employed by the Company. An "ultimate client" refers to any circumstance in which the Company is retained on behalf of a representative or agent of a client. An example of such circumstance is the situation in which the Company is retained by a law firm to provide services on behalf of the law firm (the "client") and the law firm's client (the "ultimate client").

(b) This Agreement shall be governed by, construed and enforced in accordance with the laws of the Commonwealth of Massachusetts, without regard to conflicts of laws. Employee also hereby irrevocably submits to the jurisdiction of the courts of the Commonwealth of Massachusetts and the courts of the United States of America located in the Commonwealth of Massachusetts. Employee also hereby waives, to the fullest extent permitted by applicable law, any objection that Employee may now have or may have to the personal jurisdiction in the Commonwealth of Massachusetts.

7. Miscellaneous

The terms and conditions of this Agreement shall be supplemental of and in addition to any and all other provisions of any Agreements that Employee has signed with the Company (the "Other Agreements"). To the extent that the Other Agreements contain a longer Restriction Period, such longer Restriction Period shall apply.

8. Severability

Wherever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is, for any reason, held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.
