Danvers, MA 01923

Dear Xxxxxxxx:

In connection with the termination of your employment with bcgi (the “Company”) on December 31, 2006, you are eligible to receive severance benefits if you sign and return this letter agreement to Xxx Xxxxx by February 14, 2007 in the enclosed envelope and it becomes binding between you and the Company. By signing and returning this letter agreement and not revoking your acceptance, you will be agreeing to the terms and conditions set forth in the numbered paragraphs below, including the release of claims set forth in paragraph 3. Therefore, you are advised to consult with an attorney before signing this letter agreement and you may take up to forty-five (45) days to do so. If you sign this letter agreement, you may change your mind and revoke your agreement during the seven (7) day period after you have signed it. If you do not so revoke, this letter agreement will become a binding agreement between you and the Company upon the expiration of the seven (7) day revocation period.

If you choose not to sign this letter agreement by February 14, 2007 or if you revoke your acceptance of this letter agreement during the revocation period, you shall not receive any severance benefits from the Company. Also, regardless of signing this letter agreement, you will receive four weeks of accrued vacation pay with your December 31, 2006 paycheck and you may elect to continue receiving group medical insurance pursuant to the federal “COBRA” law, 29 U.S.C. § 1161 et seq. All premium costs for “COBRA” shall be paid by you on a monthly basis for as long as, and to the extent that, you remain eligible for COBRA continuation. You should consult the COBRA materials to be provided by the Company for details regarding these benefits. All other benefits, including life insurance and long-term disability, will cease upon your Termination Date. Subject to any restrictions that may be in effect, pursuant to the Company’s stock plan, you will have up to ninety (90) days after the Termination Date to exercise any vested stock rights you may have (as provided for by the plans). All unvested stock rights will be cancelled on December 31, 2006. Finally, your eligibility for any benefits under the Company’s Supplemental Executive Retirement Plan (SERP) is governed by the Supplemental Executive Retirement Agreement dated November 1, 2002, as amended by an Amendment to Boston Communications Group, Inc. Supplemental Executive Retirement Agreement Non Founders’ Agreement in the form provided to your legal counsel concurrently with this Agreement (as amended, the “SERP Agreement”). At the most recent meeting of the Board of Directors, the Board voted to accelerate your vesting to 100% for purposes of your SERP distribution.

- 23 -

The exact amount to be paid under the SERP Agreement is determined by the SERP Plan documents based on certain actuarial calculations which will be available in January 2007. The anticipated amount to be paid you under the SERP Agreement is approximately $130,000 by January 31, 2007 and approximately $375,000 by July 31, 2007. The following numbered paragraphs set forth the terms and conditions which will apply if you timely sign and return this letter agreement and do not revoke it within the seven (7) day period:

1. Termination Date - Your effective date of termination from the Company is December 31, 2006 (the “Termination Date”). During the time period between the date of this letter and the Termination Date, you shall remain employed by the Company but you shall not and may not perform any work or otherwise act on behalf of the Company, except as specifically requested by an officer of the Company. You acknowledge that during this time period, you will continue to receive your current pay and benefits.

2. Description of Severance Benefits - The severance benefits paid to you if you sign and return this letter agreement, and do not revoke your agreement during the seven day revocation period are as follows:

(A) The Company will pay you $232,667 (two hundred thirty-two thousand, six hundred sixty-seven dollars)¹, less all applicable state and federal taxes (the “Severance Pay”). This Severance Pay will be paid in one lump-sum eight (8) days after the execution of this letter agreement but not earlier than January 5, 2007.

(B) Effective as of the Termination Date, you shall be considered to have elected to continue receiving group medical and dental insurance pursuant to the federal “COBRA” law, 29 U.S.C. § 1161 et seq. The Company shall continue to pay the share of the premium for such coverage that is paid by the Company for active and similarly-situated employees who receive the same type of coverage though January 31, 2008. The remaining balance of any premium costs, and all premium costs after January 31, 2008, shall be paid by you on a monthly basis for as long as, and to the extent that, you remain eligible for COBRA continuation. You should consult the COBRA materials to be provided by the Company for details regarding these benefits.

(C) You will receive a payment of $25,400.00 (twenty-five thousand four hundred dollars) under the Company’s Management Incentive Compensation bonus and profit sharing program (MIC) for 2006, less all applicable state and federal taxes. This payment shall be made with the Severance Pay.

vendor(s) of your choice. If this amount is to be paid directly to the outplacement services and/or training vendor, such benefit should not be considered wages. Similarly, if this amount is paid as a reimbursement to you, such benefit should not be a W-2 (wages) or 1099 (miscellaneous compensation) transaction, and therefore will not be taxable income to you. “Outplacement services and/or training” are defined to include the following:

vi. General use of any career services vendor, including the use of vendor office support and facilities, research services, and resume and business card printing;
