Item 1.01 Entry into a Material Definitive Agreement

Pursuant to a consent solicitation conducted from March 18, 2005 to March 31, 2005, The Interpublic Group of Companies, Inc. (the “Company”) entered into three supplemental indentures on March 28, 2005, one supplemental indenture on March 29, 2005 and one supplemental indenture on March 30, 2005 (collectively, the “Supplemental Indentures”). The Supplemental Indentures each provide that (i) any failure by the Company to comply with certain reporting covenants (the “Reporting Covenants”) under the supplemented indentures (the “Indentures”) during the period beginning on April 1, 2005 and ending at 5:30 p.m., New York City time, on September 30, 2005, will not constitute a default under the Indentures and (ii) if as of 5:30 p.m., New York City time, on September 30, 2005 the Company has not filed reports with the Securities and Exchange Commission required by the Indentures in a form that causes the Company to b e then current in all material respects in its filing obligations under the Securities Exchange Act of 1934, or has not filed an auditors’ certificate with the applicable trustee, the relief described in clause (i) of this sentence will cease to have any effect and the failure to comply described in clause (i) will constitute a default under the Indentures.

With respect to the Company’s 4.50% Convertible Senior Notes due 2023, the related supplemental indenture also provides for: (1) an extension from March 15, 2008 to September 15, 2009 of the date before which the Company may not redeem the notes and (2) an additional “make-whole” adjustment to the conversion rate in the event of a change of control meeting specified conditions.

The Company has agreed to pay an initial consent fee (the “Initial Consent Fee”) on April 1, 2005 or as promptly as practical thereafter to each record holder from which the Company has received and accepted consents to the amendments pursuant to the terms of the Company’s consent solicitation statement dated March 18, 2005. If the Company has not filed its Annual Report on Form 10-K for the fiscal year ending December 31, 2004 by 5:30 p.m., New York City time, on June 30, 2005, the Company has agreed to pay an additional consent fee (the “Additional Consent Fee”) on July 1, 2005 or as promptly as practical thereafter to each such record holder. For every $1,000 of principal amount of securities as to which the Company has received and accepted consents, the Initial Consent Fee is $2.50 and the Additional Consent Fee is $1.25. In the event the Company does not pay the Initial Consent Fee or the Additional Consent Fee (if app licable), the relief provided by the Supplemental Indentures will cease to have any effect and the Company’s failure to comply with the Reporting Covenants will constitute a default under the Indentures.

Item 8.01 Other Events.

On April 1, 2005, the Company issued a press release (the “Press Release”), a copy of which is attached hereto as Exhibit 99.1 and incorporated by reference herein, announcing that its consent solicitation dated March 18, 2005 had expired on March 31, 2005, and that it had accepted all consents tendered by holders of subject securities pursuant to the terms of the consent solicitation.

“(12). Adjustment for Conversion Upon a Cash Take-Over Transaction. If a Holder elects to convert Notes, pursuant to the satisfaction of the conditions described in clause (e) of paragraph 10 in the Notes in connection with a Fundamental Change referred to in clause (b) of the definition of Fundamental Change contained in Section 1.01 pursuant to which 10% or more of the consideration for the Common Stock (excluding cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights) in the transaction or transactions otherwise constituting the Fundamental Change does not consist of Publicly Traded Securities (a “Cash Take-Over Transaction”), the Company will increase the number of shares of Common Stock issuable upon conversion of the Notes by a number of additional shares of Common Stock (the “Additional Common Stock”) as set forth below. The number of shares of Additional Common Stock shall be determined by reference to the table below, based on the date on which the Cash Take-Over Transaction becomes effective (the “Effective Date”) and the price (the “Stock Price”) paid per share for the Common Stock in the Cash Take-Over Transaction. If holders of Common Stock receive only cash in the Cash Take-Over Transaction, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Sale Price of the Common Stock on the five Trading Days prior to but not including the Effective Date.

The Stock Prices set forth in the table below will be adjusted as of any date on which the Conversion Rate is adjusted. On such date, the Stock Prices shall be adjusted by multiplying:

The following table sets forth the hypothetical Stock Price and number of shares of Additional Common Stock issuable per $1,000 aggregate principal amount of Notes:

Effective Date of Fundamental Change	Stock Price on Date of Fundamental Change
Effective Date of Fundamental Change	$8.00	$10.00	$12.00	$15.00	$20.00	$25.00	$50.00	$75.00		$100.00	$200.00

March 15, 2006	47.9137	29.2768	19.1137	11.0223	5.6039	3.5500	1.3746		0.9051	0.6782	0.3390
March 15, 2007	46.1628	26.8288	16.5255	8.9261	4.3335	2.7598	1.1521		0.7656	0.5741	0.2870

March 15, 2009	40.5052	19.5364	8.0781	1.3624	0.0000	0.0000	0.0000		0.0000	0.0000	0.0000
September 15, 2009	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000	0.0000		0.0000	0.0000	0.0000

If the Stock Price or Effective Date is not set forth on the table above and the Stock Price is:

(a) between two Stock Prices on the table or the Effective Date is between two dates on the table, the number of shares of Additional Common Stock will be determined by straight-line interpolation between the number of shares of Additional Common Stock set forth for the higher and lower Stock Price and the two Effective Dates, as applicable, based on a 365-day year;

(b) in excess of $200.00 per share (subject to adjustment), no shares of Additional Common Stock will be issued upon conversion; or

(c) less than $8.00 per share (subject to adjustment), no shares of Additional Common Stock will be issued upon conversion.”

ARTICLE 4

AMENDMENT TO ARTICLE 5 OF THE INDENTURE

Section 5.01 of the Indenture with respect to the Notes is hereby amended by inserting the following sentence at the end of the last paragraph of such Section:
