 ARTICLE VIII 

Termination 
 8.01 Interpublic may terminate the employment of Executive hereunder at any time and for any reason. 
 (i) If (a) Interpublic terminates Executive’s employment involuntarily (within the meaning of Treas. Reg. § 1.409A-1(n)(1)) without Cause and Interpublic specifies a

  
 -7-

 
Termination Date less than twelve (12) months after the date on which such written notice is given (provided that such Termination Date may not be more than six (6) months after the
date on which such written notice is given), or (b) Executive resigns for Good Reason: 
 (a)
Executive’s employment hereunder shall terminate on the Termination Date specified in such notice (or, if applicable, determined in accordance with the Good Reason provisions of this Agreement); and 

(b) After the Termination Date (provided that Executive continues working until such Termination Date), Interpublic shall
make the payments and provide the benefits to Executive prescribed by subsection (ii), below. 
 (ii) The payments and benefits
prescribed by this subsection (ii) shall be as follows: 
 (a) Vacation Pay. In accordance with
Interpublic’s vacation policy, Interpublic shall pay to Executive an amount equal to all accrued, unused vacation time. Unless otherwise required by Section 8.05 hereof, such amount shall be paid to Executive in a lump sum within thirty
(30) days after the Termination Date. 
 (b) Salary Continuation. In addition, Interpublic shall pay
to Executive an amount equal to the excess of (1) twelve (12) months’ base salary at the higher of his then-current rate or the rate immediately prior to a Covered Action described in subparagraph 1.01(v)(b)(1) over (2) the base
salary paid to him for the period from the Notice Date (if applicable) through the Termination Date. Except as required by Section 8.05 hereof, such amount shall be paid in successive semi-monthly installments, commencing on Interpublic’s
first semi-monthly pay date that occurs after the Termination Date. The amount of each semi-monthly installment, before withholding, shall be equal to one-half of Executive’s base salary for one month at the rate in effect immediately prior to
the Termination Date (or, if greater, the rate in effect immediately prior to a Covered Action described in subparagraph 1.01(v)(b)(1)), with any residue in respect of a period of less than one-half of one month to be paid together with the last
installment. 

  
 -8-

 (c) Medical, Dental, and Vision Benefits. Interpublic shall provide
to Executive cash in lieu of medical, dental, and vision benefits in accordance with Section 4.2 of ESP as in effect on the Effective Date hereof, subject to the following provisions: 

(1) The “designated number of months” for purposes of determining the “severance period” under this
Agreement shall be twelve (12); provided, however, that Executive’s right to benefits under this Section 8.01(ii)(c) shall terminate immediately upon Executive’s acceptance of employment with another employer offering
similar benefits; 
 (2) Any amendment, suspension, or termination of ESP after the Effective Date that has the
effect of reducing the level of benefits required by this Section 8.01(ii)(c) shall be disregarded unless Executive expressly consents in writing to such amendment, suspension, or termination; 

(3) Executive’s right to the level of benefits required by this Section 8.01(ii)(c) shall not be conditioned on
Executive’s execution of the agreement required by Section 5 of ESP; and 
 (4) Any taxable payments
required by this Section 8.01(ii)(c) shall be delayed to the extent required by Section 8.05 hereof. 

(d) Interpublic Savings Plan. 
 (1) Executive shall not be eligible to contribute or defer (and shall not contribute or defer) any compensation with respect to the period after the Termination Date under the 401(k) Plan or any other
savings or deferred compensation plan (whether tax-qualified or nonqualified) maintained by IPG. 
 (2)
Interpublic shall pay to Executive a lump-sum amount equal to the aggregate of the matching contributions that Interpublic would have made for the benefit of Executive under the 401(k) Plan if, during the period that begins on the day after the
Termination Date and ends on the first anniversary of the Notice Date, Executive had participated in the 401(k) Plan and made pre-tax 

  
 -9-

 
deferrals and after-tax contributions to the 401(k) Plan at the same rate as in effect immediately before the Termination Date. Except to the extent required by Section 8.05 hereof, such
payment shall be made (without interest) within thirty (30) days after the first anniversary of the Notice Date. The amount of the lump-sum payment required by this subparagraph (2) shall be determined based on the matching formula
prescribed by the 401(k) Plan as in effect during the period described herein. 
 8.02 Notwithstanding the provisions of
Section 8.01, during the period of notice of termination, Executive will use reasonable, good faith efforts to obtain other employment reasonably comparable to his employment under this Agreement. Upon obtaining other employment (including work
as a consultant, independent contractor or establishing his own business), Executive will promptly notify Interpublic. 
 (i) If
Executive’s salary and other non-contingent compensation (“New Compensation”) payable to Executive in connection with his new employment equals or exceeds the amount of the salary continuation benefit prescribed by
Section 8.01(ii)(b) hereof, Interpublic shall be relieved of any obligation to make payments under Section 8.01(ii)(b). 
 (ii) Subject to subsection (iii), below, if Executive’s New Compensation is less than the amount of the salary continuation benefit prescribed by Section 8.01(ii)(b) hereof, the amount that
Interpublic is required to pay Executive each pay period under Section 8.01(ii)(b) shall be reduced by the amount of Executive’s New Compensation for such pay period. 

(iii) If Executive accepts employment with any company owned or controlled by Interpublic during the period in which payments are being
made pursuant to Section 8.01 of this Agreement, all such payments shall cease upon commencement of such employment. 

(iv) Nothing contained in this Section 8.02 shall be interpreted to preclude the payment to Executive of his accrued, unused
vacation time. 
 8.03 Executive may at any time give notice in writing to Interpublic specifying a Termination Date not less
than six (6) months after the date on which such notice is given, in 

  
 -10-

 
which event his employment hereunder shall terminate on the date specified in such notice; provided, however, that Interpublic may, at its option, upon receipt of such notice
determine an earlier Termination Date. If Executive specifies a Termination Date under this Section 8.03 (and Executive does not resign for Good Reason), he shall not be entitled to payments and benefits pursuant to Section 8.01 hereof,
but will be entitled only to regular compensation (in accordance with this Section 8.03) through his Termination Date and payment of accrued, unused vacation. During the notice period, Executive will continue to be an employee, will assist
Interpublic in the transition of his responsibilities and will continue to receive base salary and to participate in all benefit plans for which an employee at Executive’s level is eligible; provided, however, that Executive shall
not receive any bonus award that might otherwise be paid during such notice period. Interpublic may require that Executive not come in to work during the notice period. In no event, however, may Executive perform services for any other employer
during the notice period. 
 8.04 Notwithstanding the provisions of Section 8.01, Interpublic may terminate the employment
of Executive hereunder, at any time after the Commencement Date, for Cause. Interpublic shall provide Executive with thirty (30) days written notice of its intent to terminate Executive’s employment under this Section 8.04, which
notice shall (i) indicate the specific provision of Section 1.01(i) hereof on which such a termination is predicated, (ii) set forth in reasonable detail the facts and circumstances on which the termination is based, and
(iii) specify a Termination Date. Executive shall have the right, if the basis for such termination is curable, to cure such breach within fifteen (15) days after receiving such notice. Upon a termination for Cause, Interpublic shall pay
Executive his salary through the Termination Date, and Executive shall not be entitled to any bonus with respect to the year of termination, or to any other payments hereunder. 

8.05 Special Payment Rules. 
 (i) “Specified Employee” Rule. If Interpublic determines that Executive is a Specified Employee as of the Termination Date, no payment shall be made under this Article VIII before the
6-Month Pay Date; provided that (a) the delay prescribed by this Section 8.05(i) shall not apply with respect to any payment that is exempt from the six-month delay required by Section 409A(a)(2)(B)(i) of the Code 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. 

  
 -11-

 
§ 1.409A-1(b)(9) (with each installment payment required by this Agreement being treated for purposes of Section 409A as a separate payment), and (b) the delay prescribed by
this Section 8.05(i) shall not apply to any payment of current salary for the period ending on the Termination Date or unused vacation that is paid in accordance with Interpublic’s vacation policy. Each payment to which the delay
prescribed by the immediately preceding sentence applies shall be made on the later of (a) the 6-Month Pay Date or (b) the date prescribed by the applicable section of this Article VIII. Neither interest nor any other form of adjustment
shall be added to or subtracted from any payment that is delayed by reason of the application of this Section 8.05(i). 

(ii) Change of Control Rule. If Interpublic terminates Executive’s employment for any reason other than Cause within two
years after a “Change of Control” (as defined in ESP), any amount payable after the Termination Date under this Article VIII, excluding any amount payable under Section 8.01(ii)(c) (Medical, Dental and Vision Benefits), shall be paid
in a lump sum. Except as required by subsection (i), above, such lump-sum payment shall be made within thirty (30) days after the Termination Date. 
 ARTICLE IX 
 Covenants 

9.01 While Executive is employed hereunder by Interpublic he shall not, without the prior written consent of Interpublic, which will not
be unreasonably withheld, engage, directly or indirectly, in any other trade, business or employment, or have any interest, direct or indirect, in any other business, firm or corporation; provided, however, that he may continue to own
or may hereafter acquire any securities of any class of any publicly-owned company. 
 9.02 Executive shall treat as
confidential and keep secret the affairs of Interpublic and shall not at any time during the Term of Employment or thereafter, without the prior written consent of Interpublic, divulge, furnish or make known or accessible to, or use for the benefit
of, anyone other than Interpublic and its subsidiaries and affiliates any information of a confidential nature relating in any way to the business of Interpublic or its subsidiaries or affiliates or their clients and obtained by him in the course of
his employment hereunder. 

  
 -12-

 9.03 All records, papers and documents kept or made by Executive during the Term of
Employment and the preceding negotiations relating to the business of Interpublic or its subsidiaries or affiliates or their clients shall be and remain the property of Interpublic. 

9.04 All articles invented by Executive, processes discovered by him, trademarks, designs, advertising copy and art work, display and
promotion materials and, in general, everything of value conceived or created by him pertaining to the business of Interpublic or any of its subsidiaries or affiliates during the Term of Employment, and any and all rights of every nature whatever
thereto, shall immediately become the property of Interpublic, and Executive will assign, transfer and deliver all patents, copyrights, royalties, designs and copy, and any and all interests and rights whatever thereto and thereunder to Interpublic.

 9.05 During the Term of Employment and for a period of one (1) year following the later of
(x) Executive’s Termination Date or (y) the due date for the last payment to Executive under Article VIII hereof (the “Restricted Period”), Executive shall not: (i) directly or indirectly solicit any employee of
McCann or any of the companies listed on Exhibit A to this Agreement (“Mediabrands companies”) to leave such employ to enter the employ of Executive or of any person, firm or corporation with which Executive is then associated, or
induce or encourage any such employee to leave the employment of McCann or a Mediabrands company, as applicable, or to join any other company, or hire any such employee, or otherwise interfere with the relationship between McCann or a Mediabrands
company, as applicable, and any of its employees; or (ii) directly or indirectly solicit or handle on Executive’s own behalf or on behalf of any other person, firm or corporation, the type of services provided by, from, or for any person
or entity that is a client of McCann or a Mediabrands company, as applicable, that was a client of McCann or a Mediabrands company, as applicable, at any time within one year prior to Executive’s Termination Date, or that was a prospective
client of McCann or a Mediabrands company, as applicable, within the one year prior to Executive’s Termination Date (collectively “Client”), or to induce any such Client to cease to engage the services of McCann or a
Mediabrands company, as applicable, or to use the services of any entity or person that competes directly with a material business of McCann or a Mediabrands company, as applicable, where the identity of such Client, or the Client’s need,
desire or receptiveness to services offered by McCann or a Mediabrands company, as applicable, is known by Executive as a part of his employment with Interpublic. In addition, during the Term of Employment and until the due date for the last payment
to Executive under Article VIII hereof, 

  
 -13-

 
Executive shall not accept any form of employment (including as an advisor, consultant or otherwise) with an employer that is in competition with the business of McCann or a Mediabrands company.
Provided, however, that all of the above restrictions relating to Mediabrands companies will apply only if Executive’s Termination Date is prior to March 31, 2012. Executive acknowledges that these provisions are reasonable and necessary
to protect Interpublic’s legitimate business interests, and that these provisions do not prevent Executive from earning a living. 
 9.06 If at the time of enforcement of any provision of this Agreement, a court shall hold that the duration, scope or area restriction of any provision hereof is unreasonable under circumstances now or
then existing, the parties hereto agree that the maximum duration, scope or area reasonable under the circumstances shall be substituted by the court for the stated duration, scope or area. 

9.07 Executive acknowledges that a remedy at law for any breach or attempted breach of this Article IX will be inadequate, and agrees
that Interpublic shall be entitled to specific performance and injunctive and other equitable relief in the case of any such breach or attempted breach. 
 ARTICLE X 
 Arbitration 

10.01 Any controversy or claim arising out of or relating to this Agreement, or the breach thereof, including claims involving alleged
legally protected rights, such as claims for age discrimination in violation of the Age Discrimination in Employment Act of 1967, as amended, Title VII of the Civil Rights Act, as amended, and all other federal and state law claims for defamation,
breach of contract, wrongful termination and any other claim arising because of Executive’s employment, termination of employment or otherwise, shall be settled by arbitration in accordance with the Commercial Arbitration Rules of the American
Arbitration Association and Section 12.01 hereof, and judgment upon the award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. The arbitration shall take place in the city where Executive customarily
renders services to Interpublic. 
 10.02 The prevailing party in any arbitration required by Section 10.01, above, shall
be entitled to receive attorney’s fees and costs. In order to be eligible for a payment or

by March 15th of the calendar year next following the calendar year in which a final decision is rendered. 
 ARTICLE
XI 
 Assignment and Non-Duplication of Benefits 

11.01 This Agreement shall be binding upon and enure to the benefit of the successors and assigns of Interpublic. Neither this Agreement
nor any rights hereunder shall be assignable by Executive and any such purported assignment by him shall be void. 
 11.02 No
term or other provision of this Agreement shall be interpreted to require IPG to duplicate any payment or other compensation that Executive is entitled to receive under any compensation or benefit plan, program, or other arrangement sponsored or
maintained by IPG. 
 ARTICLE XII 
 Applicable Law 
 12.01 This Agreement shall be governed by and
construed 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.

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

Authority to Determine Payment Date 
 13.01 To the extent that any payment under this Agreement may be made within a specified number of days on or after any date or the occurrence of any event, the date of payment shall be determined by
Interpublic in its sole discretion, and not by Executive, his beneficiary, or any of his representatives.

between Executive and Interpublic or IPG concerning such employment and/or any compensation or bonuses. In the event of any inconsistency between the terms of an amendment to this Agreement and the terms of this Agreement in effect before such
amendment, the terms of the amendment shall govern. 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 and each amendment thereto.
Any amendment or modification to this Agreement shall be set forth in writing and signed by Executive and an authorized director or officer of Interpublic.

 Exhibit 10(iii)(A)(25) 

EXECUTIVE CHANGE OF CONTROL AGREEMENT 
 This AGREEMENT (“Agreement”) effective as of the date of execution, by and between The Interpublic Group of Companies, Inc. (“Interpublic”), a Delaware
corporation, and Nicolas Brien (the “Executive”). 
 W I T N E S S E T H: 

WHEREAS, Interpublic and the Executive are parties to an Executive Change of Control Agreement dated as of February 1, 2008 (the
“Existing Agreement”); and

absence. However, if the leave of absence is due to any medically determinable physical or mental impairment that can be expected to last for a continuous period of six (6) months or more, and such impairment causes the Executive to be unable
to perform the duties of his position of employment or any substantially similar position of employment, the preceding sentence shall be deemed to refer to a twenty-nine (29) month period rather than to a six (6) month period. For the

terminates as a result of a Qualifying Termination, Interpublic shall, within thirty (30) days after the date of the Executive’s Qualifying Termination (or such later date as required by Section 2.5 hereof), pay to the Executive a
lump-sum amount (without any discount to reflect the time value of money) equal to the Designated Number multiplied by the sum of: 
 (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 
 (iv) The Executive may not
exchange the right to reimbursement for Reimbursable Expenses set forth in this Section 4.8(b) for cash or any other benefit. 

  
 -17-

 ARTICLE 5 
 GENERAL PROVISIONS 

Section 5.1. Term of Agreement. 
 (a) Subject to subsection (b), below, this Agreement shall terminate upon the earliest of — 
 (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 5.10. Amendment. No amendment of this Agreement shall be effective unless it
is in writing and is executed by both Interpublic and the Executive. 
 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. 
 Section 5.12. Non-Duplication and Changes to Benefit Plans. 
 (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. 

(b) No term or other provision of this Agreement shall restrict the Company’s ability to amend, suspend, or terminate any or all of
its employee benefit plans and programs from time to time, or prevent any such amendment, suspension, or termination from affecting the Executive. 
 Section 5.13. Severability. If any provision of this Agreement shall be held invalid or unenforceable in whole or in part, such invalidity or unenforceability shall not affect any other provision
of this Agreement or part thereof, each of which shall remain in full force and effect. 
 Section 5.14. Construction.

 (a) The captions to the respective articles and sections of this Agreement are intended for convenience of reference only
and have no substantive significance.

word “include” shall mean include, but not limited to; and (iii) any reference to a statute or section of a statute shall also be a reference to any successor or amended statute or
section, and any regulations or other guidance of general applicability issued thereunder. 
 Section 5.15. Counterparts.
This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original but all of which together shall constitute a single instrument. 
 Section 5.16. Entire Agreement. This Agreement constitutes the entire understanding between the Company and the Executive concerning the matters set forth herein and supersedes any and all previous
agreements (including the Existing Agreement) between the Company and the Executive concerning such matters.
