The Interpublic Group of Companies, Inc.

Underwriting Agreement

Basic Provisions

The Interpublic Group of Companies, Inc., a Delaware corporation (the “Company”) proposes to issue and sell from time to time certain of its senior debt securities (the “Securities”), on terms to be determined at the time of sale. The Securities will be issued under an indenture, dated as of March 2, 2012 (as may be supplemented from time to time, the “Indenture”), between the Company and U.S. Bank National Association (the “Trustee”). Each issue of Securities may vary, as applicable, as to aggregate principal amount, maturity date, interest rate or formula and timing of payments thereof, redemption provisions, conversion provisions and sinking fund requirements, if any, and any other variable terms which the Indenture, contemplates may be set forth in the Securities as issued from time to time.

This is to confirm the arrangements with respect to the purchase of Securities (the “Underwritten Securities”) from the Company by the Representatives identified in, and the several Underwriters listed in, the applicable terms agreement entered into between the Representatives and the Company of which this Underwriting Agreement is Annex A thereto (the “Terms Agreement”). With respect to any particular Terms Agreement, the Terms Agreement, together with the provisions hereof incorporated therein by reference, is herein referred to as the “Agreement.” Terms defined in the Terms Agreement are used herein as therein defined.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-263704), relating to the Securities, including the Underwritten Securities, to be issued from time to time by the Company. The registration statement as amended to the date of the applicable Terms Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement,” and the related prospectus covering the Underwritten Securities dated in the form first used to confirm sales of those Underwritten Securities (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Basic Prospectus.” The Basic Prospectus, as supplemented by the prospectus supplement specifically relating to the Underwritten Securities in the form first used to confirm sales of the Underwritten Securities (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act) is hereinafter referred to as the “Prospectus,” and the term “preliminary prospectus” means any preliminary form of the Prospectus. For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, “Time of Sale Prospectus” means the preliminary prospectus supplement, any free writing prospectus and the pricing information set forth in Schedule II of the Terms Agreement with respect to such Underwritten Securities, and “road show” means a “road show” that is a “written communication,” including any “bona fide electronic road show” (each as defined in Rule 433(h) under the Securities Act) including the investor presentation, if any, listed on Schedule III hereto

and hereinafter referred to as the “investor presentation”, with respect to an offering of Underwritten Securities. As used herein, the terms “Registration Statement,” “Basic Prospectus,” “preliminary prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents, if any, incorporated by reference therein on the date hereof. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration Statement, the Basic Prospectus, the Time of Sale Prospectus, any preliminary prospectus or the Prospectus shall include all documents subsequently filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are deemed to be incorporated by reference therein.

Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.

5. Conditions to the Underwriters’ Obligations. The several obligations of the Underwriters to purchase Underwritten Securities pursuant to the Terms Agreement are subject to the following conditions:

6. Covenants of the Company. The Company covenants with each Underwriter as follows:

(a) During the period from the Applicable Time to the Closing Date, to furnish to the Representatives, upon request and without charge, a signed copy of the Registration Statement (including exhibits thereto and documents incorporated by reference therein) and to deliver to each of the relevant Underwriters during the period mentioned in Section 6(e) or 6(f) below, as many copies of the Time of Sale Prospectus, the Prospectus, any documents incorporated by reference therein and any supplements and amendments thereto or to the Registration Statement as the Representatives may reasonably request.

(b) During the period from the Applicable Time to the Closing Date, before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, to furnish to the Representatives a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Representatives reasonably object.

(c) During the period from the Applicable Time to the Closing Date, to furnish to the Representatives a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which the Representatives reasonably object.

(d) During the period from the Applicable Time to the Closing Date, not to take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus with respect to an offering of Underwritten Securities prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Underwritten Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) If, during such period after the first date of the public offering of the Underwritten Securities when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Underwritten Securities may have been sold by the Representatives on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(g) To arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the distribution of the Securities, provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits other than those arising out of the offering or sale of the Securities in any jurisdiction where it is not now so subject. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(h) To make generally available to the Company’s security holders and to the Representatives as soon as practicable an earning statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the effective date of the Registration Statement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(i) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the registration and delivery of the Underwritten Securities under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company and amendments and supplements to any of the foregoing, including the filing fees payable to the Commission relating to the Securities (within the time required by Rule 456(b)(1), if applicable), all printing costs

It is understood, however, that except as provided in this Section and Section 8 entitled “Indemnity and Contribution,” the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on resale of any of the Underwritten Securities by them and any advertising expenses connected with any offers they may make.

(j) During the period beginning on the date hereof and continuing to and including the Closing Date, not to offer, sell, contract to sell or otherwise dispose of any debt securities of the Company or warrants to purchase or otherwise acquire debt securities of the Company substantially similar to the Underwritten Securities (other than (i) the Underwritten Securities, (ii) commercial paper issued in the ordinary course of business, or (iii) securities or warrants permitted with the prior written consent of the Representative identified in Schedule I of the Terms Agreement with the authorization to release this lock-up on behalf of the Underwriters).

(k) To prepare a final term sheet relating to the offering of the Underwritten Securities, containing only information that describes the final terms of the Underwritten Securities or the offering in a form consented to by the Representatives, and to file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Underwritten Securities.

7. Covenants of the Underwriters. Each of the Underwriters covenants with the Company as follows:

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any free writing prospectus other than (i) a free writing prospectus that is not required under the Securities Act to be filed, (ii) any issuer free writing prospectus listed on Schedule II to the Terms Agreement or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing.

(b) Unless otherwise specified in the Terms Agreement, it has not and will not, without the prior written consent of the Company, use any free writing prospectus that contains the final terms of the Securities unless such terms have previously been included in a free writing prospectus filed with the Commission, provided that the Underwriter may use a term sheet substantially in the form set forth in Exhibit A to the Terms Agreement without the consent of the Company; provided further that the Underwriter using such term sheet shall notify the Company, and provide a copy of such term sheet to the Company, prior to, or substantially concurrently with, the first use of such term sheet.

8. Indemnity and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, Affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show, including the investor presentation, or the Prospectus or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such losses, claims, damages, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged

omission made in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act or the Prospectus or in any amendment thereof or any supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus, road show, including the investor presentation, or the Prospectus or any amendment or supplement thereto. This indemnity agreement will be in addition to any liability that any Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or

additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this paragraph, then the indemnifying party agrees that it shall be liable for any settlement effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among the Underwriters relating to the offering of the Securities) be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total purchase discounts and commissions in each case set forth on the cover of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their

relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Securities Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in any of the Company’s securities shall have been suspended by the Commission or the New York Stock Exchange; (ii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange; (iii) a banking moratorium shall have been declared by federal, Delaware or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities as contemplated in the Time of Sale Prospectus or the Prospectus (exclusive of any amendment or supplement thereto).

10. Effectiveness; Defaulting Underwriters. If any one or more Underwriters shall fail to purchase and pay for any of the Underwritten Securities agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Underwritten Securities set forth opposite their names in Schedule I to the Terms Agreement bears to the aggregate principal amount of Underwritten Securities set forth opposite the names of all the remaining Underwriters) the Underwritten Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Underwritten Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Underwritten Securities set forth in Schedule I to the Terms Agreement, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Underwritten Securities, and if such nondefaulting Underwriters do not purchase all the Underwritten Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set

forth in this Section 10, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company or any nondefaulting Underwriter for damages occasioned by its default hereunder.

11. Entire Agreement.

(a) This Agreement, together with the relevant Terms Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Underwritten Securities, represents the entire agreement between the Company and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Underwritten Securities.

(b) The Company acknowledges that in connection with the offering of the Securities: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

12. Counterparts. The Terms Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

15. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to the Representatives at the address set forth in Schedule II of the Terms Agreement; and if to the Company shall be delivered, mailed or sent to the address set forth in Schedule II of the Terms Agreement.

16. Trial by Jury. THE COMPANY (ON ITS BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS AND AFFILIATES) AND THE UNDERWRITERS HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

17. Severability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

18. Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers and of the several Underwriters set forth in or made pursuant to this Agreement will (i) remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriters, the Company, its officers or employees, or any person controlling the Company, as the case may be or (B) acceptance of the Securities and payment for them hereunder and (ii) survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

19. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation in or under this Agreement, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Optional Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the

8

Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Optional Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Optional Redemption Date.

If on the third Business Day preceding the Optional Redemption Date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Optional Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of Principal Amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Optional Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points less (b) interest accrued to the Optional Redemption Date, and

(2) 100% of the Principal Amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the Optional Redemption Date.

12

(ii) On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at an Optional Redemption Price equal to 100% of the Principal Amount of the Notes being redeemed plus accrued and unpaid interest thereon to the Optional Redemption Date.

(iii) The Company’s actions and determinations in determining the Optional Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

(b) Fewer Than All Outstanding Notes to Be Redeemed. In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a Principal Amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the Principal Amount of the Note to be redeemed. A new Note in a Principal Amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the Optional Redemption Price, on and after the Optional Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

(c) Notice of Redemption. If the Company elects to redeem Notes pursuant to Section 2.03(a) hereof, notice will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the date of redemption (the “Optional Redemption Date”) to each Holder of Notes to be redeemed. Notices of redemption may not be conditional. Any notice that is delivered in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered Holder received the notice. In any case, failure to duly give such notice to the Holder of any Note designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Note.

The notice shall identify the Notes to be redeemed and shall state:

(i) the Optional Redemption Date;

(ii) the Optional Redemption Price and, to the extent known at the time of such notice, the amount of interest (if any) payable on the Optional Redemption Date;

(iii) the name and address of the Paying Agent;

(iv) that Notes called for redemption must be presented and surrendered to the Paying Agent to collect the Optional Redemption Price plus, if any, accrued and unpaid interest thereon;

(v) that, unless the Company defaults in making payment of such Optional Redemption Price and, if any, accrued and unpaid interest thereon, interest, if any, on the Notes called for redemption will cease to accrue on and after the Optional Redemption Date, and the only remaining right of the Holder will be to receive payment of the Optional Redemption Price upon presentation and surrender to the Paying Agent of the Notes;

(d) Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 2.03(c) hereof, Notes called for redemption become due and payable on the Optional Redemption Date and at the Optional Redemption Price plus, if any, accrued and unpaid interest thereon. Upon presentation and surrender to the Paying Agent, Notes called for redemption shall be paid at the Optional Redemption Price plus, if any, accrued and unpaid interest thereon.

(e) Deposit of Optional Redemption Price. On or before 10:00 a.m. (New York City time) on the Optional Redemption Date, the Company shall deposit with the Trustee or the Paying Agent an amount of money sufficient to pay the Optional Redemption Price of, and any accrued and unpaid interest, with respect to all the Notes to be redeemed on that date other than the Notes or portions thereof called for redemption which on or prior thereto have been delivered by the Company to the Security Registrar for cancellation. The Trustee or the Paying Agent shall, as promptly as practicable, return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the Optional Redemption Price of, and any accrued and unpaid interest with respect to the Notes to be redeemed.

Prior to March 15, 2033 (three months prior to the Stated Maturity) (the “Par Call Date”), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at an Optional Redemption Price (expressed as a percentage of Principal Amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Optional Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points less (b) interest accrued to the Optional Redemption Date, and

(2) 100% of the Principal Amount of the Notes to be redeemed,

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair.

If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the Principal Amount of the Note to be redeemed. A new Note in a Principal Amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. Unless the Company defaults in payment of the Optional Redemption Price, on and after the Optional Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

If a Change of Control Repurchase Event occurs, each Holder shall have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to a Change of Control Offer on the terms set forth in the Indenture.

Subject to certain limitations, conditions and exceptions, Holders of a majority in aggregate Principal Amount of the Notes at the time outstanding may direct the Trustee in its exercise of any trust or power, including the annulment of a declaration of acceleration. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of amounts specified in clauses (1) and (2) of Section 4.01 of the Base Indenture) if it determines that withholding notice is in their interests.

Ladies and Gentlemen:

We have acted as special counsel to The Interpublic Group of Companies, Inc., a Delaware corporation (the “Company”), in connection with the sale by the Company of $300,000,000 aggregate principal amount of its 5.375% Senior Notes due 2033 (the “Notes”), pursuant to that certain Terms Agreement, dated June 6, 2023, by and among the Company and Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, as representatives of the underwriters named therein (the “Underwriters”). The Notes were issued pursuant to a Senior Debt Indenture, dated as of March 2, 2012 (the “Base Indenture”), between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “Trustee”), as supplemented by a Twelfth Supplemental Indenture, dated June 8, 2023 (the “Supplemental Indenture”), between the Company and the Trustee. The Base Indenture as supplemented by the Supplemental Indenture is herein referred to as the “Notes Indenture.” The Notes are being offered pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). This opinion is being delivered in connection with that certain Registration Statement on Form S-3 (No. 333-263704), as amended, originally filed with the Securities and Exchange Commission (the “Commission”) on March 18, 2022 (the “Registration Statement”) and the related prospectus contained in the Registration Statement, as supplemented by the final prospectus supplement relating to the Notes, dated June 6, 2023, filed with the Commission pursuant to Rule 424 under the Securities Act (as so supplemented, the “Prospectus”).

We have examined such documents as we have considered necessary for purposes of this opinion, including (i) the Registration Statement, (ii) the Prospectus, (iii) the Notes Indenture, (iv) certified copies of the certificate of incorporation and by-laws of the Company, (v) the Terms Agreement, (vi) the form of global certificate evidencing the Notes, (vii) a certificate of the Secretary of the Company, dated June 8, 2023, including the exhibits thereto, (viii) a certificate, dated June 8, 2023, from the Office of the Secretary of the State of Delaware as to the existence and good standing in the State of Delaware of the Company and (vii) such other documents and matters of law as we have deemed necessary in connection with the opinions hereinafter expressed.

We express no opinion as to the enforceability of Section 1.15 of the Base Indenture relating to currency indemnity.

The opinions expressed herein are limited to the laws of the State of New York, the General Corporation Law of the State of Delaware and the federal laws of the United States as in effect on the date of this letter and typically applicable to transactions of the type contemplated in this letter and to the specific legal matters expressly addressed herein, and no opinion is expressed or implied with respect to the laws of any other jurisdiction or any legal matter not expressly addressed herein.

The opinions set forth above are qualified in that the legality or enforceability of the documents referred to therein may be (a) subject to applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, (b) limited insofar as the remedies of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and the discretion of the court before which any enforcement thereof may be sought, and (c) subject to general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity) including principles of commercial reasonableness or conscionability and an implied covenant of good faith and fair dealing. Insofar as provisions of any of the documents referenced in this letter provide for indemnification or contribution, the enforcement thereof may be limited by public policy considerations.
