obtained by multiplying the Participant’s Final Average Pay by the Percentage; or (b) the Annual Cap (each such annual payment an “Annual Installment Payment”). Each Annual Installment Payment made pursuant to this Section 6.1 shall
be deemed a separate payment under this Plan for all purposes.

     6.2 Except as otherwise set forth in the Participant’s Senior Executive Restrictive Covenant and Retention Plan Agreement, the benefits to be paid under Section 6.1 of the Plan, if any, shall commence upon the
later of (a) the Participant’s attainment of age 55 (subject to Section 6.3 of the Plan), or (b) the calendar year following the calendar year in which the Participant dies or incurs a Separation from Service; provided, however, that the
following exceptions apply:

  
          (i) If the Participant incurs a Separation from Service because of his or her Disability, then the Participant’s benefits shall commence in the calendar year following the calendar year in which such Separation
from Service occurs;

  
          (ii) If the Participant dies prior to receiving the first payment of his or her benefits, then 100% of the benefits that would have been paid to the Participant had the Participant lived to receive all payments shall be
paid to the Beneficiary in annual payments over the total number of calendar years as to which the Company would have been obligated to make payments hereunder to the Participant; and

  
          (iii) If the Participant dies after receiving the first payment of his or her benefits, but before the Participant has received all of the payments in respect of the total number of calendar years as to which the
Company is obligated to make payments hereunder (“Payment Period”), the Company shall thereafter be obligated to make annual payments to the Beneficiary during the remainder of the Payment Period, equal to 100%

6

  
of the amount which the Company would have been obligated to pay to the Participant had the Participant lived to receive all payments.

  
          (iv) Notwithstanding any provision of the Plan to the contrary, no portion of the Participant’s benefits shall be provided to the Participant prior to the earlier of (i) the expiration of the six-month period
measured from the date of the Participant’s Separation from Service or (ii) the date of the Participant’s death. Upon the earlier of such dates, all payments deferred pursuant to this Section 6.2(iv) shall be paid in a lump sum to the
Participant. Thereafter, payments will resume in accordance with this Plan.

     6.3 Payments hereunder as a result of the Participant attaining age 55 shall commence as soon as practicable as determined by the Company but no later than the later of (i) ninety (90) days following the

Participant’s attainment of age 55 during the first ninety (90) days of the subject calendar year. Except as otherwise provided herein, all payments under this Article shall be made by the Company in each calendar year of payment during the
first ninety (90) days of the subject calendar year.

     6.4 The Company may, at any time and from time to time, seek to fund, in whole or in part, its obligation under the Plan by applying for insurance on the life of a Participant. Such Participant shall, if requested in
writing by the Company, undergo a physical examination for such purpose by medical examiners designated by the Company, and if the Participant should refuse to undergo such physical examination the Company shall have the right to terminate its
obligation under the Plan by giving written notice of such termination to the Participant.

     6.5 Upon becoming a Participant in this Plan (or with respect to a Participant who was a Participant as of December 31, 2008 (the “Surrender Date”), on the Surrender Date), each Participant shall and does
surrender any rights he or she has to receive payments to be made following cessation of such Participant’s employment to the Participant, Beneficiary or other designee of the Participant pursuant to any defined benefit pension plan sponsored
by one or more members of the Employer Group regardless of whether such plan is qualified under Section 401(a) of the Internal Revenue Code (“Post-Employment Payments”). For purposes hereof, Post-Employment Payments shall not include any
other type of payment including payments under (i) a profit-sharing or savings plan which is qualified under Section 401(a) of the Internal Revenue Code, (ii) a benefit plan, other than a defined benefit pension plan, for the payor’s employees
generally (“Employee Benefit Plan”), (iii) a plan, other than a defined benefit pension plan, for the payor’s executive officers approved by the Company that augments a benefit provided for in an Employee Benefit Plan, (iv) an
agreement financed, in whole or in part, by the Participant to the extent the payments are attributable to the financing provided by the Participant, and (v) social security benefits.

     6.6 Notwithstanding anything to contrary in this Plan, nothing in this Plan is intended to result in a change in the time or form of payment of any Post-Employment Payments that would be deemed to be “non-qualified
deferred compensation” within the meaning of Section 409A (such Post-Employment Payments referred to herein as “Non-qualified Post-Employment Payments”). If a Participant would be entitled to receive any Non-qualified
Post-Employment

7

Payments (ignoring the effect of the first sentence of Section 6.5), then (i) with respect to such Participant, the first sentence of Section 6.5 shall not apply to any Non-qualified Post-Employment Payments and (ii) the payments to which such
Participant would otherwise be entitled under this Plan shall be reduced by an amount equal to the value of such Non-qualified Post-Employment Payments (as determined by the Company), which reduction shall be applied pro-rata to each Annual
Installment Payment. This Section 6.6 shall not apply to any Participant that is a Vested Participant as of December 31, 2008.

     For purposes of clarifying the provisions of the Plan, including Article VI, the Participant shall not be deemed an Employee solely by serving as a non-executive member or Chairman of the Board (or any similar committee
of any Employer).

ARTICLE VII

more than one person or entity, describing the allocation of the payment benefit among them. A Participant may change his or her designation of a Beneficiary and thereby revoke a prior designation of a Beneficiary at any time and from time to time

to any and all other actual or possible claimants; (c) any person or entity claiming to be entitled to receive payments hereunder following the death of the Participant shall have recourse only against the person or entity to whom the Company shall
have made payment in good faith; and (d) in the event the Company, on advice of counsel, delays payment of any sums becoming due to a Beneficiary by reason of a dispute as to the legitimacy of the claim of such Beneficiary, no interest, penalty or
damage shall accrue, become payable by or be assessed against the Company by reason of such delay in payment.

Agreement (the “Agreement”) unless certain amendments are made to the Agreement. To adopt these amendments, please sign and return this letter by December 31, 2008 to the addressee below. Adopting these amendments is
for your own benefit, as failure to adopt them may result in increased tax and/or significant tax penalties to you.

          The amendments to the Agreement are required because of the enactment of Section 409A of the Internal Revenue Code (“Section 409A”). Section 409A sets forth requirements that apply to
“deferred compensation” arrangements, including agreements that provide salary continuation payments following termination of employment. Final regulations clarifying these requirements were issued last year.

          The amendments that must be made to your Agreement are discussed below. None of the amendments will have a negative impact on the amounts you receive under the Agreement.

          First, the Agreement must be amended to reflect that Section 409A only permits payments to commence upon a termination of employment if it qualifies as a “separation from service” as defined under Section
409A. Most employment terminations qualify as a separation from service under Section 409A. However, if you merely transfer from your employer to another Omnicom affiliate or continue to provide significant services to your employer or an Omnicom
affiliate following your termination, you would not incur a separation from service under Section 409A.

         Second, the Agreement is being amended to remove the provision that would have potentially reduced the amount of payments otherwise payable to you under your Agreement by payments made to you from other agreements
between you and Omnicom or one of its affiliates. Such a provision may have resulted in an impermissible acceleration of the payments under the Agreement. As

a result of this change, you will receive your payments from the Agreement without any such reduction.

          Third, the Agreement must be amended to reflect Section 409A’s anti-acceleration rules. Pursuant to these rules, payments under the Agreement cannot occur prior to the payment dates specified by the Agreement, except in very limited circumstances, such as to pay withholding or employment taxes.

          Fourth, the Agreement is being amended to provide that the Omnicom Group Inc.’s Compensation Committee may amend the Agreement at any time to comply with Section 409A’s requirements, with or without consent.

	 	amended, and the regulations and interpretations issued thereunder (“Section 409A”), specifically, within the meaning of Treas. Reg. 1.409A-1(h), as amended from time to time.

	3.      	Article VII of the Agreement is amended by adding the following sentence to the end thereof: “Notwithstanding the foregoing, amounts payable hereunder shall be prepaid only if such prepayment is not deemed a prohibited acceleration pursuant to Treas. Reg. §1.409A-3(j) and only if such prepayment would not result in income recognition by the Participant or Beneficiary prior to receipt of the payment and tax penalties as a result of a failure to meet the requirements of Section 409A.” 
	 
	4.      	Article XI of the Agreement is amended by adding a new Section 5, which shall provide the following: “This Agreement may be amended at any time and from time to time by the Committee to cause the Agreement to comply with the requirements of Section 409A, or to cause the Agreement to become exempt from the requirements of Section 409A. Any such amendment may be made without the consent of any Participant or Beneficiary, regardless of whether such amendment adversely affects any benefits or rights of a Participant or Beneficiary arising under the terms of the Agreement.”
