(b) Each Guarantor, and by its acceptance of this Guaranty, each Guaranteed Party, hereby confirms that it is the intention of all such persons that this Guaranty and the obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of any applicable law relating to bankruptcy, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Guaranteed Parties and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance.

Section 2. GUARANTY ABSOLUTE. (a) The obligations of the Guarantors are joint and several and are those of a primary obligor, and not merely a surety, and are independent of the Obligations. A separate action or actions may be brought against any Guarantor whether or not an action is brought against the Borrower, any other guarantor or other obligor in respect of the Obligations or whether the Borrower, any other guarantor or any other obligor in respect of the Obligations is joined in any such action or actions. (b) The liability of the Guarantors under this Guaranty shall be absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives, to the extent permitted by applicable law, any defenses it may now have or hereafter acquire relating to any or all of the following: (i) any lack of genuineness, validity, legality or enforceability of the Credit Agreements, the Notes or any other document, agreement or instrument relating thereto or any assignment or transfer of any thereof; (ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any waiver, indulgence, compromise, renewal, extension, amendment, modification of, or addition, consent, supplement to, or consent to departure from, or any other action or inaction under or in respect of, the Credit Agreements, the Notes or any other document, instrument or agreement relating to the Obligations or any other instrument or agreement referred to therein or any assignment or transfer of any thereof; (iii) any release or partial release of any other guarantor or other obligor in respect of the Obligations; (iv) any exchange, release or non-perfection of any collateral for all or any of the Obligations, or any release, or amendment or waiver of, or consent to departure from, any guaranty or security, for all or any of the Obligations; (v) any furnishing of any additional security for any of the Obligations; (vi) the liquidation, bankruptcy, insolvency or reorganization of the Borrower, any other guarantor or other obligor in respect of the Obligations or any action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such proceeding; or 2 <Page> (vii) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, any Guarantor. (c) This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time payment or performance of the Obligations, or any part thereof, is, upon the insolvency, bankruptcy or reorganization of the Borrower or any Guarantor or otherwise pursuant to applicable law, rescinded or reduced in amount or must otherwise be restored or returned by any Guaranteed Party, all as though such payment or performance had not been made. Section 3. WAIVERS. (a) To the extent permitted by applicable law, each Guarantor hereby unconditionally and irrevocably waives promptness, diligence, notice of acceptance and any and all other notices with respect to any of the Obligations and this Guaranty, other than the notice provided for in Section 1 hereof, and any requirement that any Guaranteed Party protect, secure, perfect or insure any security interest in or any lien on any property subject thereto or exhaust any right or take any action against the Borrower, any other guarantor or any other person or any collateral or security or any balance of any deposit accounts or credit on the books of any of the Lenders in favor of the Borrower or any Guarantor. (b) Each Guarantor hereby unconditionally and irrevocably waives any right to revoke this Guaranty and acknowledges that this Guaranty is continuing in nature and applies to all Obligations, whether existing now or in the future. (c) Each Guarantor hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or defense based upon an election of remedies by any Guaranteed Party that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Guarantor or other rights of such Guarantor to proceed against the Borrower, any other guarantor or any other person or any collateral and (ii) any defense based on any right of set-off or counterclaim against or in respect of the obligations of such Guarantor hereunder. (d) Each Guarantor hereby unconditionally and irrevocably waives any duty on the part of any Guaranteed Party to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Borrower or any of its subsidiaries now or hereafter known by such Guaranteed Party.

Section 4. SUBROGATION.

[DATE] [GUARANTOR] - [STATE OF INCORPORATION] By: -------------------------------------- Title: ----------------------------------- Address: --------------------------------- Facsimile: ------------------------------- 1 <Page> EXHIBIT G-1 - FORM OF OPINION OF OUTSIDE COUNSEL OF THE SUBSIDIARY GUARANTOR [Date] To each of the Lenders in the below-referenced Credit Agreement [NAME OF THE SUBSIDIARY GUARANTOR] Ladies and Gentlemen: We have acted as special counsel to [name of the Subsidiary Guarantor] (the "SUBSIDIARY GUARANTOR") in connection with the preparation, execution and delivery of the subsidiary guaranty (the "SUBSIDIARY GUARANTY") pursuant to Section 5.01(i) of the Five Year Credit Agreement, dated as of June 27, 2000 and amended and restated as of December 31, 2002 (as amended to date, the "CREDIT AGREEMENT"), among The Interpublic Group of Companies, Inc. (the "COMPANY"), the Lenders parties thereto, Citigroup Global Markets Inc. (formerly known as Salomon Smith Barney, Inc.), as lead arranger and book manager, Bank One, NA, SunTrust Bank and HSBC Bank USA, as co-arrangers, Bank One, NA, as documentation agent, SunTrust Bank, as syndication agent, and Citibank, N.A., as Agent for said Lenders. In arriving at the opinions expressed below, we have examined the following documents: (1) an executed copy of the Credit Agreement; (2) an executed copy of the Subsidiary Guaranty; and (3) executed copies of the other documents furnished by the Subsidiary Guarantor pursuant to Section 5.01(i) of the Credit Agreement. In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate records of the Subsidiary Guarantor and such other instruments and other certificates of public officials, officers and representatives of the Subsidiary Guarantor and such other persons, and we have made such investigations of law, as we have deemed necessary as a basis for the opinions expressed below. In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed (including, without limitation, the accuracy of the representations and warranties of the Company in the Credit Agreement and of the Subsidiary Guarantor in the Subsidiary Guaranty). Based upon the foregoing and subject to the further assumptions and qualifications set forth below, it is our opinion that: 1. The Subsidiary Guarantor has the corporate power to enter into the Subsidiary Guaranty and to perform its obligations thereunder. 1 <Page> 2. The execution and delivery by the Subsidiary Guarantor of the Subsidiary Guaranty have been duly authorized by all necessary corporate action of the Subsidiary Guarantor. 3. The performance by the Subsidiary Guarantor of its obligations under the Subsidiary Guaranty (a) does not require any consent, approval, authorization, registration or qualification of or with any governmental authority of the United States, [the State of Delaware or the State of New York], and (b) does not result in a violation of any applicable United States federal [or New York State law, rule or regulation or the Delaware General Corporation]. 4. The Subsidiary Guaranty is a valid, binding and enforceable obligation of the Subsidiary Guarantor. Insofar as the foregoing opinions relate to the validity, binding effect or enforceability of any agreement or obligation of the Subsidiary Guarantor, (a) we have assumed that each party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Subsidiary Guarantor regarding matters of the federal law of the United States of America[, the law of the State of New York or the General Corporation Law of the State of Delaware]) and (b) such opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors' rights generally and to general principles of equity. We have assumed that any assignments made by or among the guaranteed parties of their rights and obligations under the Subsidiary Guaranty will not contravene New York Judiciary Law Section 489 (which makes it a criminal offense to take an assignment of a debt obligation with the intent of and for the purpose of bringing an action or proceeding thereon). We note that the designations in Section 13(b) of the Subsidiary Guaranty are (notwithstanding the waiver contained in Section 14(b)) subject to the power of such federal court to transfer actions pursuant to 28 U.S.C. Section 1404(a) or to dismiss such actions or proceedings on the grounds that such a federal court is an inconvenient forum for such action or proceeding. With respect to the first sentence of Section 13(b) of the Subsidiary Guaranty, we express no opinion as to the subject matter jurisdiction of any United States federal court to adjudicate any action relating to the Subsidiary Guaranty where jurisdiction based on diversity of citizenship under 28 U.S.C. Section 1332 does not exist. The opinion expressed in paragraph 3 above relates only to those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type referred to in the Subsidiary Guaranty. The foregoing opinions are limited to the law of the [State of New York, the General Corporation Law of the State of Delaware] and the federal law of the United States, but we express no opinion as to any state securities or Blue Sky laws or United States federal securities laws. 2 <Page> We are furnishing this opinion letter to you solely for your benefit in connection with the Subsidiary Guaranty. This opinion letter is not to be used, circulated, quoted or otherwise referred to for any other purpose.

(the "COMPANY"), the Lenders parties thereto, Citigroup Global Markets Inc. (formerly known as Salomon Smith Barney, Inc.), as lead arranger and book manager, Bank One, NA, SunTrust Bank and HSBC Bank USA, as co-arrangers, Bank One, NA, as documentation agent, SunTrust Bank, as syndication agent, and Citibank, N.A., as Agent for said Lenders. Terms defined in the Credit Agreement are used herein as therein defined. I have acted as [General Counsel] for [name of the Subsidiary Guarantor] (the "SUBSIDIARY GUARANTOR") in connection with the preparation, execution and delivery of the Subsidiary Guaranty. In arriving at the opinions expressed below, I have examined the following documents: (1) An executed copy of the Credit Agreement. (2) An executed copy of the Subsidiary Guaranty. (3) The other documents furnished by the Subsidiary Guarantor pursuant to Section 5.01(i) of the Credit Agreement. (4) A copy of the [Articles] [Certificate] of Incorporation of the Subsidiary Guarantor and all amendments thereto (the "CHARTER"). (5) A copy of the by-laws of the Subsidiary Guarantor and all amendments thereto (the "BY-LAWS"). (6) A certificate of the Secretary of State of [ ], dated __________, 2003, attesting to the continued corporate existence and good standing of the Subsidiary Guarantor in that State. In addition, I have examined the originals, or copies certified or otherwise identified to my satisfaction, of such other corporate records of the Subsidiary Guarantor, certificates of public officials and of officers of the 4 <Page> Subsidiary Guarantor and such other persons as I have deemed necessary as a basis for the opinions expressed below. In rendering the opinions expressed below, I have assumed the authenticity of all documents submitted to me as originals and the conformity to the originals of all documents submitted to me as copies. In addition, I have assumed and have not verified the accuracy as to factual matters of each document I have reviewed (including, without limitation, the accuracy of the representations and warranties of the Company in the Credit Agreement and of the Subsidiary Guarantor in the Subsidiary Guaranty). Based upon the foregoing and subject to the further assumptions and qualifications set forth below, it is my opinion that: 1. The Subsidiary Guarantor is a corporation validly existing and in good standing under the laws of the State of [ ]. 2. The execution, delivery and performance by the Subsidiary Guarantor of the Subsidiary Guaranty to be delivered by it, and the consummation of the transactions contemplated thereby, are within the Subsidiary Guarantor's corporate powers, have been duly authorized by all necessary corporate action, and do not contravene (i) the Charter or the By-laws or (ii) any material contractual or legal restriction known to me contained in any material document to which the Subsidiary Guarantor is a party or by which it is bound. The Subsidiary Guaranty has been duly executed and delivered on behalf of the Subsidiary Guarantor. 3. To the best of my knowledge, no authorization, approval or other action by, and no notice to or filing with, any third party is required for the execution, delivery and performance by the Subsidiary Guarantor of the Subsidiary Guaranty. 4. To the best of my knowledge, there are no pending or overtly threatened actions or proceedings against the Subsidiary Guarantor or any of its subsidiaries before any court, governmental agency or arbitrator that purport to affect the validity, binding effect or enforceability of the Subsidiary Guaranty or the consummation of the transactions contemplated thereby or that are likely to have a materially adverse effect upon the financial condition or operations of the Subsidiary Guarantor and its subsidiaries taken as a whole. The foregoing opinions are limited to the law of the State of [New York][, the General Corporation Law of the State of Delaware] and the Federal law of the United States. 5 <Page> I am furnishing this opinion letter to you solely for your benefit in connection with the Subsidiary Guaranty.
