(a) The greater of (i) the Executive’s annual base salary for the calendar year in which the Qualifying Termination occurs (determined on the basis of the Executive’s annual salary in effect immediately prior to such Qualifying Termination) or (ii) the Executive’s annual base salary for the calendar year in which the Change of Control occurs (determined on the basis of the Executive’s annual salary in effect immediately prior to such Change of Control); plus

(b) The greater of (i) the Executive’s Incentive Performance award under the 2009 Performance Incentive Plan or any successor thereto (“Target EIP Award”) for the calendar year in which the Qualifying Termination occurs or (ii) the Executive’s Target EIP Award for the calendar year in which the Change of Control occurs, as such Target EIP Award is in effect immediately prior to such Change of Control.

Section 2.2. Medical, Dental, and Vision Benefits. If the Executive’s employment terminates as a result of a Qualifying Termination, Interpublic shall make cash payments to the Executive in lieu of continuing medical, dental, and vision benefits, in accordance with Section 4.2 of the Interpublic Executive Severance Plan (“ESP”), subject to the following provisions:

-8-

(a) The “designated number of months” for purposes of determining the Executive’s “severance period” and “COBRA period” under ESP shall be the Designated Number of Months set forth in Section 1.7 hereof;

(b) Any amendment, suspension, or termination of ESP after the date of this Agreement that has the effect of reducing the level of benefits required by this Section 2.2, shall be disregarded unless the Executive expressly consents in writing to such amendment, suspension, or termination; and

(c) The Executive’s right to the level of benefits required by this Section 2.2 shall not be conditioned on the Executive executing the agreement required by Section 5 of ESP.

Section 2.3. CAP Supplement.

(a) If (x) the Executive’s employment terminates as a result of a Qualifying Termination and (y) the Executive participates in the Interpublic Capital Accumulation Plan (“CAP”), Interpublic shall pay to the Executive a lump-sum amount (without any discount to reflect the time value of money) equal to the sum of (i) plus (ii) plus (iii), where:

(i) equals the balance of the Executive’s CAP account (including any unvested balance) immediately before the Qualifying Termination plus the sum of the annual dollar credits that would have been added to the Executive’s account under CAP on each December 31st after the Executive’s Termination of Employment if he had remained employed by the Company continuously through the last day of the Severance Period (provided that this paragraph (i) shall not require duplication of any amount that is added to the Executive’s account under CAP in accordance with the terms thereof);

(ii) equals (A) the dollar credit that would have been added to the Executive’s account under CAP on December 31st of the calendar year in which the Severance Period ends if the Executive had remained employed by the Company continuously through such December 31st, multiplied by (B) a fraction the numerator of which is the number of days from January 1st of such calendar year through the last day

-9-

of the Severance Period and the denominator of which is three hundred sixty-five (365); and

(iii) equals (A) the interest crediting rate under CAP for the calendar year in which the Executive’s account balance under CAP is paid, multiplied by (B) the vested balance of the Executive’s account under CAP as of January 1st of such year, multiplied by (C) a fraction the numerator of which is the number of days from January 1st of such year through the date on which the Executive’s account balance under CAP is paid and the denominator of which is three hundred sixty-five (365).

Except as required by Section 2.5 hereof, Interpublic shall make the payment required by this Section 2.3 within thirty (30) days after the date of the Executive’s Qualifying Termination.

(b) Before a Change of Control, Interpublic shall contribute to an Unsecured Trust an amount that an Outside Auditor engaged by Interpublic, at Interpublic’s expense, concludes, in its best judgment (considering the information available to such Outside Auditor at the time of the calculation and the time constraints on completing the calculation), is equal to the amount the Executive would be entitled to receive under this Section 2.3 if the Executive had a Qualifying Termination immediately after the Change of Control. For purposes of this calculation, the Outside Auditor shall assume that (i) payment of the amount described in the immediately preceding sentence will be due within thirty (30) days after the Change of Control and (ii) the rate of return on assets of the Unsecured Trust will be the interest crediting rate under CAP for the calendar year in which the Change of Control occurs.

Section 2.4. SERIP Supplement.

(a) If (x) the Executive’s employment terminates as a result of a Qualifying Termination and (y) the Executive participates in the Interpublic Senior Executive Retirement Income Plan (“SERIP”), Interpublic shall pay to the Executive a lump-sum amount (without any discount to reflect the time value of money) equal to the amount (if any) that the Executive would be entitled to receive under SERIP if he had remained employed by the Company continuously through the end of the Severance Period, plus any additional amount that becomes payable by reason of SERIP’s special change of control vesting provisions. Except as

-10-

required by Section 2.5 hereof, Interpublic shall make the payment required by this Section 2.4 within thirty (30) days after the date of the Executive’s Qualifying Termination.

(b) Before a Change of Control, Interpublic shall contribute to an Unsecured Trust an amount that an Outside Auditor engaged by Interpublic, at Interpublic’s expense, concludes, in its best judgment (considering the information available to such Outside Auditor at the time of the calculation and the time constraints on completing the calculation), is equal to the amount the Executive would be entitled to receive under this Section 2.4 if the Executive had a Qualifying Termination immediately after the Change of Control. For purposes of this calculation, the Outside Auditor shall assume that (i) payment of the amount described in the immediately preceding sentence will be due within thirty (30) days after the Change of Control and (ii) the rate of return on assets of the Unsecured Trust will be the plan interest rate specified by SERIP.

Section 2.5. Special Payment Rules.

(a) Specified Employee Rules. If Interpublic determines that the Executive is a “specified employee” (within the meaning of Section 409A(a)(2)(B)(i) of the Code, and determined in accordance with Treas. Reg. § 1.409A-1(i)) on the date of his Termination of Employment, Interpublic shall make the payments specified by paragraphs (i), (ii), and (iii) of this Section 2.5(a) and shall not make any payments pursuant to Section 2.1, Section 2.3, or Section 2.4 hereof (except insofar as such Sections determine the amount required by this Section 2.5(a)).

(i) Interpublic shall pay the Base Amount at the time or times prescribed by the terms of the applicable Other Arrangement through the last day of the sixth calendar month that begins after the date of the Executive’s Termination of Employment;

(ii) Within thirty (30) days after the date of the Executive’s Qualifying Termination, Interpublic shall pay to the Executive in a lump sum the excess (if any) of (A) the sum of the amounts prescribed by this Article 2 over (B) the aggregate Base Amount payable under all Other Arrangements. The amounts in clauses (A) and

-11-

(B) of this paragraph (ii) shall be determined without any adjustment (such as a discount) to reflect the time value of money; and

(iii) On the 6-Month Pay Date (as defined below), Interpublic shall pay to the Executive an amount equal to the excess (if any) of (A) the sum of the aggregate amounts prescribed by this Article 2 (taking into account Section 4.5) over (B) the aggregate amount paid in accordance with paragraphs (i) and (ii), above (determined without any adjustment (such as interest) to reflect the time value of money). The “6-Month Pay Date” shall be Interpublic’s first semi-monthly pay date for the seventh calendar month that begins after the date of the Executive’s Termination of Employment (or, if earlier, a date determined by Interpublic that occurs within the ninety (90) day period immediately following the date of the Executive’s death).

(b) This Section 2.5 shall be interpreted consistent with the intent that any delay shall apply only to the extent required to comply with the requirements of Section 409A of the Code and that no delay shall apply with respect to any payment that is not subject to the requirements of Section 409A by reason of the “short-term deferral” rule described in Treas. Reg. §1.409A-1(b)(4) or the “two-year, two-time” rule described in Treas. Reg. §1.409A-1(b)(9).

Section 2.6. Death Prior to Payment. If the Executive dies after his Qualifying Termination but before all of the payments required by this Article 2 have been made, Interpublic shall pay to the Executive’s estate an amount equal to the sum of the then-unpaid amounts required by this Article 2. Such payment shall be made in a lump sum (without any discount to reflect the time value of money) as soon as practicable, and no more than ninety (90) days, after the Executive’s death. The date of payment shall be determined by Interpublic in its sole discretion, and not by the Executive or his personal representative.

ARTICLE 3

TAX MATTERS

Section 3.1. Withholding and Taxes. The Company may withhold (or cause to be withheld) from any amounts payable to the Executive or on his behalf hereunder any or all federal, state, city, or other taxes that the Company reasonably determines are required to be

-12-

withheld pursuant to any applicable law or regulation. However, the Executive shall be solely responsible for paying all taxes (including any excise taxes) on any compensation (including imputed compensation) and other income provided to him or on his behalf, regardless of whether taxes are withheld. No provision of this Agreement shall be construed (a) to limit the Executive’s responsibility under this Section 3.1 or (b) to transfer to or impose on the Company any liability relating to taxes (including excise taxes) on compensation (including imputed compensation) or other income under this Agreement.

Section 3.2. Forfeiture of Certain Parachute Payments.

(a) Notwithstanding any provision in this Agreement to the contrary, if subsection (b), below, applies, the Executive shall forfeit amounts payable to the Executive under this Agreement to the extent an Outside Auditor determines is necessary to ensure that the Executive is not reasonably likely to receive a “parachute payment” within the meaning of Section 280G(b)(2) of the Code.

(b) This subsection (b) shall apply if —

(i) any payment to be made under this Agreement is reasonably likely to result in the Executive receiving a “parachute payment” (as defined in Section 280G(b)(2) of the Code), and

(ii) the Executive’s forfeiture of payments due under this Agreement would result in the aggregate after-tax amount that the Executive would receive being greater than the aggregate after-tax amount that the Executive would receive if there were no such forfeiture.

(c) Interpublic shall engage, at Interpublic’s expense, an Outside Auditor to determine (i) whether any amount shall be forfeited pursuant to subsection (a), above, and (ii) the amount of any such forfeiture. The Outside Auditor’s determination shall be conclusive and binding.

(d) If the Outside Auditor engaged pursuant to subsection (c), above, determines that adverse tax consequences relating to Section 280G of the Code (determined on a

-13-

net after-tax basis) could be avoided by the Executive forfeiting payments under one or more Other Arrangements, and such Other Arrangements permit a forfeiture to avoid adverse tax consequences relating to Section 280G of the Code, the Executive shall not forfeit the right to receive any amount due under this Agreement unless and until he has forfeited the right to all payments under such Other Arrangements.

ARTICLE 4

COLLATERAL MATTERS

Section 4.1. Nature of Payments. All payments and benefits provided to the Executive under this Agreement shall be considered either severance payments in consideration of his past services on behalf of the Company or payments in consideration of the covenant set forth in Section 4.7 hereof. No payment or benefit provided hereunder shall be regarded as a penalty on the Company.

Section 4.2. Mitigation. The Executive shall not be required to mitigate the amount of any payment or benefit provided for in this Agreement by seeking other employment or otherwise. Unless the Executive breaches the covenant set forth in Section 4.7 hereof, the amount of any payment provided for herein shall not be reduced by any remuneration that the Executive may earn after his Termination of Employment.

Section 4.3. Setoff for Debts. Interpublic may reduce the amount of any payment or benefit otherwise due to the Executive under Article 2 hereof by any amount that the Executive owes to the Company pursuant to a written instrument executed by the Executive, but only if the Company has not already recovered such amount by setoff or otherwise and, to the extent required by Treas. Reg. § 1.409A-3(j)(4)(xiii), (a) the debt was incurred in the ordinary course of the Executive’s relationship with the Company, (b) the entire amount of reduction in any taxable year does not exceed $5,000, and (c) the reduction is made at the same time and in the same amount as required by the terms of such written instrument.

Section 4.4. Benefits Not Addressed in this Agreement. The effect of a Change of Control or a Qualifying Termination on the rights of the Executive with respect to any compensation, awards, or benefits under any Other Arrangement that does not provide for salary

-14-

continuation payments and that is not expressly addressed in Article 2 (including rights under any deferred compensation arrangement, any Executive Special Benefit Agreement (“ESBA”), and the 2009 Performance Incentive Plan and any predecessor or successor thereto (collectively, the “PIP”)) shall be determined solely by the terms of the governing documents for such Other Arrangement, and not by the terms of this Agreement.

Section 4.5. Coordination with Employment Contract, ESP, CAP, and SERIP. The payments and benefits required by Article 2 hereof shall be in lieu of (and not in addition to) any payments under CAP, SERIP, or an Other Arrangement that provides for salary continuation payments to which the Executive might have a claim by reason of a Qualifying Termination, whether such Other Arrangement is executed before or after the date hereof, unless expressly provided otherwise in such Other Arrangement; provided that if Other Arrangements provide for a payment (or payments) by reason of a Qualifying Termination that is (or are) larger in the aggregate (determined without regard to the time value of money) than the severance payment prescribed by Section 2.1 hereof, the Company shall pay the Executive the larger amount (in lieu of the amount prescribed by Section 2.1, and without any adjustment for interest) in a lump sum (without any discount to reflect the time value of money) at the time prescribed by Section 2.1 (or such later date as required by Section 2.5 hereof). If the Executive resigns for Good Reason, he shall be deemed to have satisfied any notice requirement for resignation, and any service requirement following such notice, under any employment contract between the Executive and Interpublic or a Subsidiary. No provision of this Agreement shall be construed to reduce, limit, or otherwise affect in any way any benefits payable to the Executive under Article 2 hereof, any ESBA, any deferred compensation arrangement, the PIP, or any Other Arrangement that does not provide for salary continuation payments and is not expressly addressed in Article 2.

Section 4.6. Funding. Except as required by Section 2.3(b), Section 2.4(b), and Section 4.8(c) hereof, this Agreement does not require the Company to set aside any amounts that may be necessary to satisfy its obligations hereunder. Any assets that the Company sets aside to fund the Company’s obligations under this Agreement, whether in an Unsecured Trust or otherwise, shall be subject to the claims of the Company’s creditors in the event of the Company’s bankruptcy or insolvency.

-15-

Section 4.7. Covenant of Executive.

(a) If the Executive has a Qualifying Termination that entitles him to a payment under Article 2 hereof, the Executive shall not, during the eighteen (18) months next following the date of his Termination of Employment, either (i) solicit any employee of the Company to leave such employ and to enter into the employ of, or to provide services to, the Executive or any person with which the Executive is associated or (ii) solicit or handle on his own behalf, or on behalf of any person with which the Executive is associated, the advertising, public relations, sales promotion or market research business of any person that is a client of the Company as of the date of the Executive’s Termination of Employment.

(b) The Executive acknowledges that the provisions of this Section 4.7 are a material inducement to Interpublic entering into this Agreement, that such provisions are reasonable and necessary to protect the legitimate business interests of the Company, and that such provisions do not prevent the Executive from earning a living. If at the time of enforcement of any provision of this Agreement, a court with jurisdiction shall hold that the duration, scope, or restrictiveness of any provision hereof is unreasonable under circumstances now or then existing, the parties agree that the maximum duration, scope, or restriction reasonable under the circumstances shall be substituted by the court for the stated duration, scope, or restriction.

(c) The Executive acknowledges that a remedy at law for any breach or attempted breach of this Section 4.7 will be inadequate, and agrees that the Company shall be entitled to specific performance and injunctive and other equitable relief in the case of any such breach or attempted breach. This Section 4.7 shall not limit any other right or remedy that the Company may have under applicable law or any other agreement between the Company and the Executive.

Section 4.8. Legal Expenses.

(a) Each party hereto shall pay its own costs and expenses (including legal fees) incurred in connection with the preparation, negotiation and execution of this Agreement.

-16-

(b) Interpublic shall reimburse the Executive for any legal fees and expenses that the Executive incurs during the Executive’s life as a result of the Company contesting the validity, the enforceability, or the Executive’s interpretation of, or any determination under, this Agreement (collectively “Reimbursable Expenses”). In order to ensure compliance with the requirements of Treas. Reg. § 1.409A-3(i)(1)(iv):

(i) The Executive shall submit any request for reimbursement for any Reimbursable Expense in writing to Interpublic (accompanied by any evidence that Interpublic reasonably requests in writing within thirty (30) days after Interpublic is first notified that such Reimbursable Expense is incurred) within one-hundred eighty (180) days after the applicable Reimbursable Expense is incurred (or, if later, within thirty (30) days after Interpublic requests in writing evidence of such Reimbursable Expense);

(ii) Interpublic shall pay to the Executive the amount of any Reimbursable Expenses within thirty (30) days after Interpublic receives the Executive’s written request for reimbursement (and in any event by the end of the Executive’s taxable year next following the taxable year in which the expense was incurred); provided that if Interpublic determines that the Executive is a “specified employee” (within the meaning of Section 409A(a)(2)(B)(i) of the Code, and determined in accordance with Treas. Reg. § 1.409A-1(i)) at the time of his Termination of Employment, payment shall not be made before the first day of the seventh month that begins after the Executive’s Termination of Employment, and if this paragraph (ii) prescribes an earlier payment date, payment shall be made, without interest, on Interpublic’s first semi-monthly pay date for the seventh month that begins after the Executive’s Termination of Employment;

(iii) The amount of fees and expenses eligible for reimbursement during one year shall not affect the amount of Reimbursable Expenses that the Executive may incur during any other year; and

Such letter of credit shall not expire before the later of (x) the date this Agreement terminates by its terms or (y) September 1, 2020.

(i) September 1, 2013, if a Change of Control has not occurred on or before such date;

(ii) the date of the Executive’s Termination of Employment if such Termination of Employment is not a Qualifying Termination; or

(iii) the expiration of a number of years after a Change of Control equal to the Designated Number plus three (3).

(b) Notwithstanding any provision of this Section 5.1, the Company’s obligations under Section 4.8 hereof and all obligations of the Company and the Executive that arise before termination of this Agreement shall survive the termination of this Agreement. In addition, if this Agreement is terminated and the Executive subsequently experiences a Qualifying Termination, Interpublic shall pay any severance to which the Executive may be entitled under any Other Arrangement (such as an employment agreement or ESP) in a lump sum at the time required by Section 2.1 hereof, and any benefits payable under CAP and SERIP shall

-18-

be paid at the time(s) prescribed by Section 2.3 and Section 2.4 hereof (in each case, subject to Section 2.5 hereof).

Section 5.2. Payments to be Made in Cash. Except as otherwise expressly provided herein, all payments required by this Agreement shall be made in cash.

Section 5.3. Obligation to Make Payments. Interpublic may satisfy any provision of this Agreement that obligates Interpublic to make a payment or contribution, or to provide a benefit, by causing another party, such as a Subsidiary or the trustee of an Unsecured Trust, to make the payment or contribution or to provide the benefit.

Section 5.4. Governing Law. Except as otherwise expressly provided herein, this Agreement and the rights and obligations hereunder shall be construed and enforced in accordance with the laws of the State of New York, without regard to any rule or principle concerning conflicts or choice of law that might otherwise refer construction or enforcement to the substantive law of another jurisdiction.

Section 5.5. Code Section 409A. This Agreement shall be construed, administered, and interpreted in accordance with the requirements of Section 409A of the Code. If the Company or the Executive determines that any provision of this Agreement is or might be inconsistent with such requirements, the parties shall attempt in good faith to agree on such amendments to this Agreement as may be necessary or appropriate to avoid adverse tax consequences under Section 409A of the Code. No provision of this Agreement shall be interpreted or construed to transfer any liability for a failure to comply with Section 409A of the Code from the Executive or any other individual to the Company.

Section 5.6. Successors to the Company. This Agreement shall inure to the benefit of Interpublic and its subsidiaries and shall be binding upon and enforceable by Interpublic and any successor thereto, including any person or persons (within the meaning of Sections 13(d) and 14(d) of the 1934 Act) acquiring directly or indirectly the business or assets of Interpublic whether by merger, consolidation, sale or otherwise, but shall not otherwise be assignable by Interpublic. Without limiting the foregoing sentence, Interpublic shall require any successor (whether direct or indirect, by merger, consolidation, sale of stock or assets, or

-19-

otherwise) to the business or assets of Interpublic, expressly, absolutely and unconditionally to assume, and to agree to perform under, this Agreement in the same manner and to the same extent as Interpublic would have been required to perform it if no such succession had taken place. As used in this Agreement, “Interpublic” shall mean Interpublic as heretofore defined and any successor to its business or assets that becomes bound by this Agreement either pursuant to this Agreement or by operation of law.

Section 5.7. Successor to the Executive. This Agreement shall inure to the benefit of and shall be binding upon and enforceable by the Executive and his personal and legal representatives, executors, administrators, heirs, distributees, legatees and, subject to Section 5.8 hereof, his designees (collectively, his “Successors”). If the Executive dies while amounts are or may be payable to him under this Agreement, references hereunder to the “Executive” shall, where appropriate, be deemed to refer to his Successors.

Section 5.8. Nonalienability. Except to the extent that Interpublic determines is necessary to comply with a domestic relations order (as defined in Section 414(p)(1)(B) of the Code), no right of or amount payable to the Executive under this Agreement shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, hypothecation, encumbrance, charge, execution, attachment, levy or similar process, or (except as provided in Section 4.3 hereof) to setoff against any obligation or to assignment by operation of law. Any attempt, voluntary or involuntary, to effect any action prohibited by the immediately preceding sentence shall be void.

Section 5.9. Notices. All notices provided for in this Agreement shall be in writing. Notices and other correspondence (including any request for reimbursement) to Interpublic shall be deemed given when personally delivered or sent by certified or registered mail or overnight delivery service to The Interpublic Group of Companies, Inc., l114 Avenue of the Americas, New York, New York l0036, Attention: Corporate Secretary. Notices to the Executive shall be deemed given when personally delivered or sent by certified or registered mail or overnight delivery service to the last address for the Executive shown on the records of the Company. Either Interpublic or the Executive may, by notice to the other, designate an address other than the foregoing for the receipt of subsequent notices.

Section 5.11. Waivers. No waiver of any provision of this Agreement shall be valid unless it is in writing and executed by the party giving such waiver. No waiver of a breach of any provision of this Agreement shall be deemed to be a waiver of any subsequent breach or a waiver of either such provision or any other provision of this Agreement. No failure or delay on the part of either the Company or the Executive to exercise any right or remedy conferred by law or this Agreement shall operate as a waiver of such right or remedy, and no exercise or waiver, in whole or in part, of any right or remedy conferred by law or herein shall operate as a waiver of any other right or remedy.

(a) No term or other provision of this Agreement shall be interpreted to require the Company to duplicate any payment or other compensation that the Executive is entitled to receive under an Other Arrangement.
