If the Consultant designates an individual other than his surviving spouse as the beneficiary of all or a portion of the Account, such individual may elect to change the time and manner of distribution of the portion of the Account subject to the beneficiary designation on -3- the same basis and subject to the same rules as if the Account were held under the Deferred Compensation Plan and such individual were named as the Consultant's beneficiary thereunder.

Unless the distribution of the Account is subject to acceleration pursuant to Section 2(c)(ii) or Section 2(c)(iii), no distribution of the amounts credited to the Account shall be made before the payment date designated by the Consultant (or his beneficiary) on the most recently filed Initial Election or Subsequent Election. SECTION 3. Manner of Distribution. (a) Manner of Distribution. Amounts credited to an Account shall be distributed, pursuant to an Initial Election or Subsequent Election in either (i) a lump sum payment or (ii) substantially equal annual installments over a five (5), ten (10) or fifteen (15) year period or (iii) substantially equal monthly installments over a period not exceeding fifteen (15) years. (b) Small Balances. Notwithstanding any Initial Election or Subsequent Election to the contrary: (i) Distributions pursuant to Initial Elections or Subsequent Elections shall be made in one lump sum payment unless the portion of the Account subject to distribution, as of both the date of the Initial Election or Subsequent Election and the benefit commencement date, has a value of more than $10,000; and (ii) Following the end of the Term, if the amount credited to the Account has a value of $25,000 or less, the Company may, in its sole discretion, direct that such amount be distributed to the Consultant (or his beneficiary, as applicable) in one lump sum payment. SECTION 4. Crediting of Income, Gains and Losses on Account. The Company shall credit income, gains and losses with respect to the Account as if it were invested in the Income Fund. SECTION 5. Status of Deferred Amounts. All Consultant Compensation deferred under this Amendment shall continue for all purposes to be a part of the general funds of the Company. SECTION 6. Consultant's and Beneficiaries' Status as General Creditors. The Account shall at all times represent a general obligation of the Company. The Consultant (and his beneficiaries) shall be general creditors of the Company with respect to this obligation, and shall not have a secured or preferred position with respect to the Accounts. Nothing contained herein shall be deemed to create an escrow, trust, custodial account or fiduciary relationship of any kind. Nothing contained herein shall be construed to eliminate any priority or preferred position of a the Consultant (or his beneficiaries) in a bankruptcy matter with respect to claims for wages. -4- SECTION 7. No Alienation of Benefits. Except as otherwise required by applicable law, the right of the Consultant (and his beneficiaries) to any benefit or interest under any of the provisions of this Amendment shall not be subject to encumbrance, attachment, execution, garnishment, assignment, pledge, alienation, sale, transfer, or anticipation, either by the voluntary or involuntary act of the Consultant (or the Consultant's beneficiaries) or by operation of law, nor shall such payment, right, or interest be subject to any other legal or equitable process. SECTION 8. Death of Consultant. (a) Death of Consultant. The Consultant's Account shall be distributed in accordance with the last Initial Election or Subsequent Election made by the Consultant before his death, unless the Consultant's surviving spouse or other beneficiary timely elects to accelerate or defer the time or change the manner of payment pursuant to Section 2(c)(ii) or Section 2(c)(iii). (b) Designation of Beneficiaries. The Consultant (and his beneficiaries) shall have the right to designate one or more beneficiaries to receive distributions in the event of the Consultant's (or his beneficiaries') death by filing with the Company a beneficiary designation on the form provided by the Company for such purpose. The designation of a beneficiary or beneficiaries may be changed by the Consultant or his beneficiaries at any time prior to their death by the delivery to the Company of a new beneficiary designation form. SECTION 9. Interpretation; Notices. The purpose of this Amendment is to permit the Consultant to defer the receipt of his Consultant Compensation on substantially the same basis as if the Consultant Compensation constituted "compensation" eligible for deferral under the terms and conditions of the Comcast Corporation 2002 Deferred Compensation Plan, and the Amendment shall be construed consistent with such purpose. If the Consultant or his beneficiaries do not receive timely payment of benefits to which such individual believes he or she is entitled under the Amendment, such individual may make a claim for benefits to the Company which shall be administered on substantially the same basis as would apply if such claim were a claim for benefits under the Deferred Compensation Plan. Claims for benefits under the Amendment, and all other filings referenced in the Amendment, shall be treated as notices pursuant to the Agreement. SECTION 10. Withholding of Taxes. Whenever the Company is required to credit deferred Consultant Compensation to the Account, the Company shall have the right to require the Consultant to remit to the Company an amount sufficient to satisfy any federal, state and local withholding tax requirements prior to the date on which the deferred Consultant Compensation shall be deemed credited to the Account, or take any action whatever that it deems necessary to protect its interests with respect to tax liabilities. The Company's obligation to credit deferred Consultant Compensation to the Account shall be conditioned on the Consultant's compliance, to the Company's satisfaction, with any withholding requirement. To the maximum extent possible, the Company shall satisfy all applicable withholding tax requirements by withholding tax from other Consultant Compensation or other compensation payable by the Company to the Consultant, or by the Consultant's delivery of cash to the Company in an amount equal to the applicable withholding tax, as determined by the Company in good faith. -5- SECTION 11. Miscellaneous Provisions. (a) Effect of Amendment. This Amendment is intended only to amend Section 5 of the Agreement, relating to the timing of payment of Consultant Compensation, as provided in this Amendment. Each other provision of the Agreement shall continue in full force and effect. (b) Tax Matters. The Consultant acknowledges that: (i) The Company has advised him to consult his tax advisor with respect to the federal, state and local income tax consequences of making Initial Elections and Subsequent Elections pursuant to the Amendment. (ii) The Company has delivered to him a copy of the Prospectus for the Deferred Compensation Plan and he has read the provisions of the Prospectus relating to tax consequences. (c) Counterparts.
