SEPARATION AGREEMENT

THIS AGREEMENT (the “Agreement”), by and between COCA-COLA ENTERPRISES INC., a Delaware corporation (the “Company”), and Patrick J. Mannelly (“Mr. Mannelly”).

WHEREAS, Mr. Mannelly has given notice of his resignation from the Company, and the Company desires to provide Mr. Mannelly with separation benefits to recognize the value he has provided to the Company during his many years of service to the Company.

NOW, THEREFORE, for valuable consideration, the sufficiency of which is hereby acknowledged, the parties do hereby agree as follows:

1. Termination Date. Mr. Mannelly agrees that his employment with the Company will terminate, by resignation, on August 16, 2004 (“Termination Date”).

2. Separation Pay. The Company agrees that after the execution of, and the revocation period related to, this Agreement it will voluntarily pay Mr. Mannelly $34,500 each month through January 31, 2007. All payments under this Agreement shall be made through the Company’s payroll and shall be subject to tax withholding applicable to wages.

3. Payments in Lieu of Executive Management Incentive Plan. The Company will pay Mr. Mannelly amounts equal to the bonuses, if any, to which he would have been entitled under the Executive Management Incentive Plan (the “MIP”) for calendar years 2004, 2005, and 2006. The amount of each such payment will be determined as if Mr. Mannelly had remained a Senior Vice President of the Company having an annual salary of $414,000. Specifically, during first quarter of 2005, 2006, and 2007, the Company will make such payments to Mr. Mannelly for the 2004, 2005 and 2006 calendar years, respectively.

4. Reimbursement for Certain Expenses. Mr. Mannelly shall be entitled to receive reimbursements for his tax and financial planning expenses and club dues during the period for which he is receiving payments under this Agreement. Such expenses shall be reimbursed by the Company upon the presentation of invoices, receipts or other evidence reasonably acceptable to the Company.

5. Employee Benefits Plans. Mr. Mannelly’s participation in the Company’s employee benefits plans for active employees shall cease on the later of the effective date of this Agreement or on the date provided under the terms of such plan, except as otherwise provided in this Paragraph, as follows:

6. Stock Grant Programs. As of the effective date of this Agreement the Company shall modify the terms of Mr. Mannelly’s equity awards, as follows:

7. Reservation of Rights. Notwithstanding any other provision of this Agreement, the Company reserves the unilateral right at any time to modify or terminate any benefit plan, bonus program, stock option plan, or fringe benefit program under which Mr. Mannelly participates or may participate (so long as such modification or termination affects the plans’ or programs’ participants or potential participants generally and not just Mr. Mannelly), and, in the event of such action, the amount of Mr. Mannelly’s benefits, awards, or grants under such plans or programs shall be determined according to the terms of such plans or programs as modified or terminated and not the terms of this Agreement.

8. General Release. In consideration for the above separation pay, Mr. Mannelly agrees to release the Company and each of its directors, officers, employees, agents, subsidiaries and affiliates from any and all charges, complaints, claims, liabilities, obligations, actions, causes of action, suits, demands, costs, losses, damages and expenses, of any nature whatsoever, known or unknown, including, but in no way limited to, any claim under Title VII of the Civil Rights Act of 1964; The Americans With Disabilities Act (ADA); The Age Discrimination in Employment Act (ADEA); The Fair Labor Standards Act (FLSA); The Family and Medical Leave Act (FMLA); and The Employee Retirement Income Security Act of 1974, as amended (ERISA); arising out of his employment relationship or the termination of his employment relationship, which Mr. Mannelly now has, owns or holds, or claims to have, own or

hold, or which he at any time heretofore had, owned or held, or claimed to have, own or hold against the Company.

9. No Competition. Mr. Mannelly agrees that for a period of two years following the effective date of this Agreement, Mr. Mannelly shall not, directly or indirectly engage in, participate in or have any interest as a partner, joint venturer, proprietor, employee, officer, director, agent, security holder, creditor or in any other capacity, or be otherwise associated with or have any other direct or indirect financial interest in or in connection with the business or operations of PepsiCo, Inc., The Pepsi Bottling Group, Inc., Cadbury Schweppes plc, or any other bottler of carbonated soft drinks (including any business, firm, person, partnership, corporation related to such company) having operations within the territories in which the Company and its subsidiaries conducted bottling operations at the effective date of this Agreement. Provided, however, that nothing herein shall be deemed to prevent or limit the right of Mr. Mannelly to own capital stock or debt securities of any corporation, so long as the securities are publicly traded in the over-the-counter market or on any securities exchange, and so long as Mr. Mannelly does not acquire beneficial ownership (as determined under Rule 13d-3 of the Securities Exchange Act of 1934) of more than one percent of the issuer’s outstanding equity securities of any class. Mr. Mannelly agrees that this covenant is reasonable with respect to its duration, geographical area and scope.

Mr. Mannelly represents and acknowledges that he has been afforded the right and opportunity to consult with an attorney prior to executing this Agreement, that he has twenty-one (21) days within which to consider this Agreement, that he has seven (7) days following its execution within which to revoke this Agreement, and that this Agreement, and compensation or benefits hereunder, will not become effective until the revocation period has expired.
