                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:  What is the proposed merger?

A:  True North and Interpublic have agreed to a merger in which True North will
    merge with, and become, a wholly owned subsidiary of Interpublic.

Q:  What will I receive in the merger for my True North common stock?

A:  You will receive 1.14 shares of Interpublic common stock for each share of
    your True North common stock. This is the exchange ratio.

Q:  Are shares of Interpublic common stock traded on any stock exchange?

A:  Yes. Shares of Interpublic common stock are traded under the symbol "IPG"
    on the New York Stock Exchange.

Q:  What do I need to do now?

A:  After carefully reading and considering the information contained in this
    document, just vote your shares following the instructions contained in
    this document and the proxy card included with it, so that your shares may
    be represented at the special meeting. If you do not vote your shares in
    connection with the merger proposal, it will have the same effect as voting
    against the merger proposal.

Q:  Should I send in my stock certificates now?

A:  No. You will receive instructions for exchanging your stock certificates
    after the merger is completed.

Q:  If my shares are held in street name by my broker, will my broker vote my
    shares for me?

A:  No. Your broker can vote your shares only if you provide instructions on
    how to vote.

    You should instruct your broker to vote your shares, following the
    directions provided by your broker. Your failure to instruct your broker
   on how to vote your shares will be the equivalent of voting against the
   merger.

Q:  How do I vote my 401(k) plan shares?

A:  If you have a balance in the True North Stock Fund within the True North
    Retirement Plan, by completing the proxy card being mailed with this
    document, you will instruct the trustee for the plan, Fidelity Management
    Trust Company, to vote your 401(k) plan shares. Voting instructions must be
    received on or before June 14, 2001.

Q:  Can I change my vote after I have mailed my proxy card or provided
    instructions to my broker?

A:  Yes. You can change your vote at any time before your proxy is voted at the

                                    SUMMARY

   This summary highlights key aspects of the merger which are described in
greater detail elsewhere in this document. It does not contain all of the
information that may be important to you. To better understand the merger, and
for a more complete description of the legal terms of the merger, you should
read this entire document carefully, including the Annexes, and the additional
documents to which we refer you. You can find information with respect to these
additional documents in "Where You Can Find More Information" on page 69.

The Companies (see pages 55 and 57)

 The Interpublic Group of Companies, Inc.
 1271 Avenue of the Americas
 New York, NY 10020
 Telephone: (212) 399-8000

   Interpublic is one of the world's largest organizations of advertising
agencies and communications-services companies. Interpublic has more than
48,000 employees and offices in 127 countries. Interpublic had revenue of
approximately $5.6 billion in 2000.

 True North Communications Inc.
 101 East Erie Street
 Chicago, Illinois 60611
 Telephone: (312) 425-6500

   True North is a global advertising and marketing communications holding
company. True North has more than 13,000 employees and offices in more than 98
countries and territories. True North had revenue of approximately $1.6 billion
in 2000.

The Merger (see page 44)

   In the merger, True North will merge with, and become, a wholly owned
subsidiary of Interpublic. For each share of your True North common stock you
will receive 1.14 shares of Interpublic common stock.

   Interpublic will not issue fractional shares in the merger. As a result, the
total number of shares of Interpublic common stock that you receive in the
merger will be rounded down to the nearest whole number. You will receive a
cash payment equal to the value, based on the closing price on the day of the
merger, of the remaining fraction of a share of Interpublic common stock that
you would otherwise receive.

   The merger agreement, which is the primary legal document that governs the
merger, is attached as Annex A. You are encouraged to read the merger agreement
carefully.

Recommendation to Stockholders (see page 28)

   The True North Board has approved the merger agreement and recommends that
you vote "FOR" the merger proposal.

Opinion of Financial Advisor to True North (see page 30)

   On March 18, 2001, the True North Board received an oral opinion (later
confirmed in writing) from its financial advisor, Morgan Stanley & Co.
Incorporated, that, as of that date, the exchange ratio pursuant to the merger
agreement was fair from a financial point of view to the holders of shares of
True North common stock. The full text of the opinion is attached as Annex B.
We urge you to read the entire opinion carefully for the assumptions made,
procedures followed, matters considered and limits on the scope of Morgan
Stanley's review in rendering its opinion. Morgan Stanley's opinion was
addressed to the True North Board for the purpose of its evaluation of the
merger and does not constitute a recommendation to any True North stockholder
as to how to vote with respect to the merger proposal.

Material Federal Income Tax Consequences (see page 42)

   The receipt of shares of Interpublic common stock in the merger generally
will be tax-free to True North stockholders for United States income tax
purposes, except for tax on cash received for fractional shares. Tax matters
are very complicated, and the tax consequences of the merger to you will depend
on the facts of your particular situation. We

                                       3


urge you to consult your tax advisor for a full understanding of the tax
consequences of the merger to you.

Anticipated Accounting Treatment (see page 40)

It is expected that the merger will qualify as a pooling of interests for
accounting purposes. This means that Interpublic and True North will be treated
for accounting purposes as if they had always been combined.

Treatment of True North Stock Options (see page 44)

Except for options held by non-employee directors, each of the outstanding True
North stock options will, in accordance with its existing terms, become
exercisable upon the merger. Any unexercised options will convert into
Interpublic stock options, subject to adjustments to the exercise price and the
number of underlying shares based on the exchange ratio.

The Special Meeting (see page 19)

The special meeting of True North stockholders will be held on June 19, 2001.
The record date for determining True North stockholders entitled to receive
notice of and to vote at the meeting is the close of business on May 7, 2001.
On that date, there were 50,832,347 outstanding shares of True North common
stock. On the record date, directors and executive officers of True North and
their affiliates owned approximately 4.0% of the outstanding shares of True
North common stock.

The affirmative vote of the holders of a majority of the outstanding shares of
True North common stock is necessary to adopt the merger agreement. No other
vote of the stockholders of True North is required for the merger to occur.

Markets and Market Prices (see page 53)

Interpublic common stock is traded under the symbol "IPG" on the New York Stock
Exchange. True North common stock is traded under the symbol "TNO" on the New
York Stock Exchange. The per share closing prices for Interpublic common stock
and True North common stock on March 16, 2001, the last trading day before the
public announcement of the merger, and May 8, 2001, the most recent trading day
for which prices are available prior to the printing of this document, are set
forth below. The table also sets forth the pro forma equivalent per share value
for shares of True North common stock, obtained by multiplying the closing

Interests of True North's Directors and Management in the Merger (see page 37)

You should be aware of conflicts of interest, and of the benefits available to
directors and executive officers of True North, when considering the True North
Board's recommendation of the merger. The directors and executive officers of
True North have interests in the merger that are in addition to, or different
from, their interests as True North stockholders. The True North Board was
aware of these conflicts of interest when it approved the merger. These
interests relate to:

 .  rights to accelerated vesting of options issued under the True North stock
    option plan;

 .  the termination of restrictions on outstanding True North restricted
    stock;

 .  existing employment agreements between True North and its executive
    officers which provide for the payment of severance benefits in the event
    the officer resigns following the merger due to specified adverse changes
    in the terms of the executive's employment;

 .  rights to accelerated payment of severance benefits payable under
    employment agreements upon termination of employment;

  . True North's Asset Protection Plan, which provides that specified
    executive officers who are not parties to employment agreements would
    receive severance benefits in the event they resign due to specified
    adverse changes in their employment or are terminated without cause within
    two years following the adoption of the merger agreement by the True North
    stockholders;

 .  rights to directors' and officers' insurance coverage and to
    indemnification with respect

                                       4


    to acts and omissions in their capacities as directors and officers of
    True North; and

 .  the contribution to a trust of an amount sufficient to pay, when due, the
    benefits that have accrued under specified deferred compensation plans of
    True North.

Furthermore, the merger agreement provides that on the day of the merger:

 .  David A. Bell, the Board chairman and chief executive officer of True
    North, and J. Brendan Ryan, a director of True North and chief executive
    officer of FCB Worldwide, a principal operating unit of True North, will
    become members of the Interpublic Board; and

 .  David A. Bell will become vice-chairman of Interpublic.

Conditions to the Merger (see page 50)

   Interpublic and True North will not complete the merger unless a number of
conditions are satisfied or waived, including:

 .  adoption of the merger agreement by True North stockholders;

 .  receipt of approval for listing on the New York Stock Exchange of the
    shares of Interpublic common stock to be issued in the merger;

 .  receipt of regulatory approvals and third party consents and the absence
    of legal restraints;

 .  effectiveness of the registration statement, which includes this document,
    and the absence of any stop order; and

 .  issuance of opinions by attorneys for Interpublic and True North as to the
    tax-free nature of the merger, except with respect to cash payments for
    fractional shares.

In addition, the completion of the merger is subject to the satisfaction, or
waiver by Interpublic, of the condition that the independent auditors for
Interpublic and True North provide opinions relating to the accounting of the
business combination as a pooling of interests.

Regulatory Approvals (see page 40)

   The Hart-Scott-Rodino Antitrust Improvements Act and the rules promulgated
under this Act by the Federal Trade Commission require, in connection with the
merger, the provision of notifications and information to the Antitrust
Division of the Department of Justice and the FTC and the satisfaction of
specified waiting period requirements. On April 18, 2001, Interpublic and True
North filed the required pre-merger notification and report forms with the
Antitrust Division and the FTC. The waiting period in connection with this
filing is expected to expire on May 18, 2001, absent an early termination,
extension or request for additional information. We may not complete the merger
until the satisfaction of this waiting period requirement. Additional filings
and clearances under this Act may be required in connection with the receipt by
a True North stockholder of Interpublic stock with a value in excess of $50
million and the indirect acquisition by Interpublic of a minority investment
held by True North.


   The transaction is also subject to antitrust and other regulatory clearances
by non-U.S. authorities, including those representing the European Union, South
Africa, Canada and Israel.

   The satisfaction of these regulatory conditions may jeopardize or delay
completion of the merger or may reduce the anticipated benefits of the merger.
The merger agreement provides that Interpublic need not agree to conditions in
connection with obtaining regulatory clearances and approvals if the conditions
would have a material and adverse impact on Interpublic, True North or the
benefits that Interpublic would otherwise have derived from the merger.

                                       5



Termination of the Merger Agreement (see page 51)

   Interpublic and True North can jointly agree to terminate the merger
agreement at any time before completing the merger. In addition, either company
can terminate the merger agreement if:

 .  the other party breaches representations, warranties, covenants or
    agreements contained in the merger agreement in any material respect and
    the breach is not cured within thirty business days after notice of the
    breach;

 .  a legal prohibition against the merger becomes permanent and final;

 .  the merger has not been completed by September 14, 2001, although, if all
    governmental clearances and approvals required for the completion of the
    merger have not then been obtained, that date may be extended to December
    13, 2001; or

 .  the True North stockholders do not adopt the merger agreement at the
    special meeting.

   Interpublic can also terminate the merger agreement if:

 .  True North fails to comply with its obligations to refrain from soliciting
    or taking other specified actions in connection with acquisition proposals
    to True North by third parties;

 .  the True North Board withdraws or adversely modifies its approval or
    recommendation of the merger;

 .  any person or entity, other than Interpublic and its affiliates, becomes
    the beneficial owner of 15% or more of the outstanding shares of True
    North common stock;

 .  the True North Board recommends or resolves to recommend another
    acquisition proposal; or

 .  a tender offer or exchange offer for 15% or more of the outstanding shares
    of True North common stock is commenced and the True North Board fails to
    recommend against acceptance of that offer.

Termination Fee (see page 51)

   True North would be required to pay Interpublic a termination fee of
$80,000,000 if the merger agreement is terminated under specified
circumstances.

the audited consolidated financial statements of Interpublic, except for

Recent Developments--Interpublic

   On April 26, 2001, Interpublic announced results for the first quarter of
2001. Interpublic reported a net loss of $38.4 million or $0.12 per share in
the first quarter of 2001 versus net income of $42.9 million or $0.14 per share
in the first quarter of 2000. In the first quarter of 2001, Interpublic
recorded a $160.1 million pretax charge ($0.33 per share) to recognize the
impairment of investments primarily in publicly-traded companies, including
marchFIRST, Inc. which declared bankruptcy in early April. In the first quarter
of 2000, Interpublic recorded $36.1 million ($0.07 per share) in restructuring
charges related to Lowe Lintas.

   Interpublic also announced revised expectations for 2001 financial
performance. Due to the challenging economic environment, higher net interest
expense and tax rates in 2001 versus 2000 and due to a higher number of shares
outstanding, Interpublic expects to generate earnings per share of $1.40 to
$1.45 in 2001, compared to $1.51 in 2000, assuming no deterioration in economic
activity.

   You should read the entire announcement, including the financial data, about
the first quarter. This announcement is included in the current report on Form
8-K filed with the Commission by Interpublic on April 27, 2001 and incorporated
into this document by reference. In addition, you should read the Quarterly
Report on Form 10-Q for the quarter ended March 31, 2001 that Interpublic
expects to file no later than May 15, 2001, which will also be incorporated
into this document by reference. See "Where You Can Find More Information" on
page 69 to learn how you can obtain these reports.

   On May 1, 2001, True North announced its results for the first quarter ended
March 31, 2001. True North reported net income of $9.7 million or $0.19 per
diluted share in the first quarter of 2001 compared to net income of $7.0
million or $0.14 per diluted share in the first quarter of 2000. The net income

   You should read the entire announcement, including the financial data, about
the first quarter. This announcement is included in the current report on Form
8-K filed with the Commission by True North on May 1, 2001 and incorporated
into this document by reference. In addition, you should read the Quarterly

Selected Unaudited Pro Forma Combined Condensed Financial Data

   The following selected unaudited pro forma combined condensed financial data
gives effect to the merger as if it had occurred at the dates and at the
commencement of the periods indicated using the pooling of interests method of
accounting for business combinations and the agreed upon exchange ratio of 1.14
shares of Interpublic common stock for each share of True North common stock.

   You should read the information presented below in conjunction with the
financial statements and the notes to the financial statements for Interpublic
included in Interpublic's Annual Report on Form 10-K for the year ended
December 31, 2000 and in conjunction with the financial statements and the
notes to the financial statements for True North included in True North's
Annual Report on Form 10-K for the year ended December 31, 2000. We have
incorporated Interpublic's and True North's Annual Reports on Form 10-K for the
year ended December 31, 2000 into this document by reference. See "Where You

Interpublic and True North. In addition, you should read the information
presented below in conjunction with the unaudited pro forma combined condensed
financial information and the notes to that information included in this
document beginning on page 59.

   The unaudited pro forma information below, while helpful in illustrating the
financial characteristics of the combination of Interpublic and True North
under one set of assumptions, does not attempt to predict or suggest future
results. Moreover, the unaudited pro forma information below does not attempt
to show what the financial condition or the results of operations of the
combined company would have been if the merger had occurred at the dates
indicated below or at the commencement of the periods indicated below.

   As discussed in Note 3 to the Pro Forma Combined Condensed Financial
Information on page 64, it is expected that restructuring and integration costs
will be incurred once the merger has been completed. The amount and nature of
these costs have not been finalized and neither the costs associated with
restructuring and integration nor any related savings has been included in the
Pro Forma Combined Condensed Financial Data.

                                  RISK FACTORS

   You should consider the following matters in conjunction with the other
information included or incorporated by reference in this document in deciding
whether to vote in favor of the merger proposal.

You will receive a fixed number of shares of Interpublic common stock for each
of your shares of True North common stock despite changes in the market value
of True North common stock and Interpublic common stock.

   You will receive 1.14 shares of Interpublic common stock for each of your
shares of True North common stock. The merger agreement does not provide for
any adjustment of this exchange ratio if the trading price of either True North
common stock or Interpublic common stock fluctuates, and True North is not
permitted to "walk away" from the merger solely because of changes in the
market price of Interpublic common stock. Accordingly, the market value of
Interpublic common stock that you will receive upon the merger's completion
will fluctuate with the trading price of Interpublic common stock and may
decrease from the date you submit your proxy. The market value of Interpublic
common stock is likely to fluctuate based on general market and economic
conditions, Interpublic's business and prospects and other factors.

   In addition, the exchange of certificates representing your shares of True
North common stock for certificates representing shares of Interpublic common
stock will not take place immediately upon completion of the merger. You will
thus be unable to sell or otherwise transfer these shares of Interpublic common
stock for a period following completion of the merger. The market value of the
shares of Interpublic common stock you receive in the merger may be either
lower or higher at the time you receive your certificates representing shares
of Interpublic common stock, and so become able to sell those shares, than at
the time of the merger.

Provisions in the merger agreement may discourage other companies from trying
to acquire True North even though those companies might be willing to offer
greater value to True North stockholders than Interpublic has offered in the
merger agreement.

   Provisions in the merger agreement relating to the termination fee and the
ability of True North to terminate the agreement may discourage other companies
from trying to acquire True North.

   True North has agreed to pay a termination fee to Interpublic under
specified circumstances, including circumstances where a third party other than
Interpublic acquires or seeks to acquire True North. This provision may
discourage other companies from trying to acquire True North.

   Furthermore, True North is not entitled to terminate the merger agreement
except under the following circumstances:

  .  Interpublic consents to the termination;

  .  Interpublic breaches its representations, warranties or covenants in any
     material respect and fails to cure the breach within 30 business days;

  .  a legal prohibition against the merger becomes permanent and final;

  .  the merger has not been completed by September 14, 2001, although, if
     all governmental clearances and approvals required for the completion of
     the merger have not then been obtained, that date may be extended to
     December 13, 2001; or

  .  the True North stockholders do not adopt the merger agreement at the
     special meeting.

                                       13


Accordingly, in the absence of any of these circumstances, True North is not
entitled to terminate the merger agreement even if a superior acquisition
proposal were made to the True North Board. This limitation on the ability of
True North to terminate the merger agreement may discourage other companies
from trying to acquire True North.

   Those companies that are discouraged from trying to acquire True North as a
result of these provisions may have otherwise been willing to offer greater
value to True North stockholders than Interpublic has offered in the merger
agreement.

Shares of Interpublic common stock are subject to different market risks than
shares of True North common stock.

   Upon completion of the merger, holders of shares of common stock of True
North will become holders of shares of common stock of Interpublic. The
business, strategy, financial condition, results of operations and common stock
of Interpublic differ in material respects from those of True North.
Accordingly, holders of shares of Interpublic common stock are subject to
different market risks than holders of shares of True North common stock. For a
description of and other information about the common stock of Interpublic and
the differences between the common stock of Interpublic and the common stock of
True North, see "Unaudited Comparative Per Share Data" on page 12, "Market
Prices and Dividends" on page 53, "Description of Interpublic Share Capital" on
page 65, "Comparative Rights of Holders of True North Common Stock and
Interpublic Common Stock" on page 66 and the registration statements of True
North that we have incorporated by reference and described under "Where You Can
Find More Information" on page 69 below. For descriptions of the businesses,
strategies, financial conditions and results of operations of Interpublic and
True North, see "Business of Interpublic" and "Business of True North" on pages
55 and 57 and the discussions in the reports on Form 10-K that we have
incorporated by reference and described under "Where You Can Find More
Information" on page 69 below.

The market price of Interpublic common stock may decline as a result of the
merger.

   The market price of Interpublic common stock may decline as a result of the
merger for a number of reasons, including if:

  .  the integration of Interpublic and True North is unsuccessful;

  .  Interpublic does not achieve the perceived benefits of the merger as
     rapidly or to the extent anticipated by investors and financial or
     industry analysts; or

  .  the effect of the merger on Interpublic's financial results is not
     consistent with the expectations of investors and financial or industry
     analysts.

Interpublic and True North may not realize expected synergies or cost savings.

   The companies may not be able to increase the scope of the services they
each provide to their respective client bases and give rise to other synergies
and cost savings described in "Recommendation of the True North Board;
Considerations of the True North Board" beginning on page 28. Interpublic and
True North are developing, but have not yet finalized, plans for obtaining
operating synergies and cost savings after the merger. The implementation of
these plans will present challenges involving the coordination of the
operations and personnel of the two companies and may give rise to the
diversion of the attention of management and unanticipated liabilities and
costs. The geographically dispersed operations of the two companies may
compound these challenges.

                                       14


The performance of the combined company will be affected by its ability to
retain key personnel.

   Employees, including creative, research, media, account and practice group
specialists, and their skills and relationships with clients, are among the
most important assets of Interpublic and True North. The inability to retain
management and employees after the merger may have a material adverse effect on
the combined company. Among the factors that may compound the challenge of
retaining True North employees are:

  .  Many of the existing employment agreements between True North and its
     executive officers and key employees provide for severance benefits in
     the event the officer or key employee resigns following the merger due
     to specified adverse changes in the terms of his or her employment.

  .  True North's Asset Protection Plan provides that some employees who are
     not parties to employment agreements would receive severance benefits in
     the event they resign due to specified adverse changes in their
     employment within two years following the adoption of the merger
     agreement by the True North stockholders.

  .  All unvested stock options held by True North employees will convert
     into options for Interpublic common stock and vest upon completion of
     the merger. Substantially all of these option holders are expected,
     after exercising their options, to be free to sell their shares of
     Interpublic common stock shortly following the merger.

  .  Upon the merger, each outstanding share of restricted True North common
     stock will convert into shares of Interpublic common stock and no longer
     be subject to restrictions. Substantially all of the holders of
     restricted stock are expected to be free to sell their shares of
     Interpublic common stock shortly following the merger.

We may lose existing clients, retain clients on less favorable terms and impede
our ability to attract new clients as a result of the merger.

   The competition in the advertising and marketing-services industry for
clients is fierce and the performance of the combined company will be affected
by its ability to retain the existing clients of Interpublic and True North and
to attract new clients. Our ability to retain existing clients and to attract
new clients may, in some cases, be limited by clients' policies on conflicts of
interest. These policies can in some cases prevent one agency and, in limited
circumstances, different agencies within the same holding company, from
performing similar services for competing products or companies. Those
conflicts could result in clients terminating their relationship with the
agencies of the combined company or reducing the projects for which they retain
those agencies. As part of an effort to assure that these clients would not
leave as a result of the merger, True North and Interpublic may need to agree
to modify the terms of their existing agreements with clients in an adverse
manner. Moreover, because of the combined company's larger number of clients,
there could be a greater likelihood of conflicts with potential new clients in
the future. If the combined company fails to maintain existing clients or
attract new clients, its business may be materially and adversely impacted.

The receipt of required regulatory approvals may jeopardize or delay completion
of the merger or may reduce the anticipated benefits of the merger.

   The completion of the merger is subject to regulatory clearances and
approvals by authorities consisting primarily of antitrust regulators from the
United States, the European Union, South Africa, Canada and Israel. We may not
be able to obtain the requisite regulatory clearances and approvals within the
time frame that the merger agreement contemplates or without accepting
conditions that would be detrimental to the combined company. In addition, we
have been advised that we may complete the merger before we have obtained
regulatory approvals and clearances in Colombia, Slovakia and Turkey so long as
we postpone integration and other changes to the operations of Interpublic and
True North in these three jurisdictions until after we have obtained the
applicable approvals and clearances there. The merger agreement provides that
Interpublic need not agree to conditions in connection with obtaining
regulatory clearances and approvals if the conditions would have a material and
adverse impact on Interpublic, True North or the benefits that Interpublic
would otherwise have derived from the merger.

                                       15


Directors and executive officers of True North have conflicts of interest that
may have influenced their decision to approve the merger.

   You should be aware of conflicts of interest, and of the benefits available
to directors and executive officers of True North, when considering the True
North Board's recommendation of the merger. The directors and executive
officers of True North have interests in the merger that are in addition to, or
different from, their interests as True North stockholders. The True North
Board was aware of these conflicts of interest when it approved the merger.
These interests relate to:

  .  rights to accelerated vesting of options issued under the True North
     stock option plan;

  .  the termination of restrictions on outstanding True North restricted
     stock;

  .  existing employment agreements between True North and its executive
     officers which provide for the payment of severance benefits in the
     event the officer resigns following the merger due to specified adverse
     changes in the terms of the executive's employment;

  .  rights to accelerated payment of severance benefits payable under
     employment agreements upon termination of employment;

  .  True North's Asset Protection Plan, which provides that specified
     executive officers who are not parties to employment agreements would
     receive severance benefits in the event they resign due to specified
     adverse changes in their employment or are terminated without cause
     within two years following the adoption of the merger agreement by the
     True North stockholders;

  .  rights to directors' and officers' insurance coverage and to
     indemnification with respect to acts and omissions in their capacities
     as directors and officers of True North; and

  .  the contribution to a trust of an amount sufficient to pay, when due,
     the benefits that have accrued under specified deferred compensation
     plans of True North.

Furthermore, the merger agreement provides that on the day of the merger:

  .  David A. Bell, the Board chairman and chief executive officer of True
     North, and J. Brendan Ryan, a director and chief executive officer of
     FCB Worldwide, a principal unit of True North, will become members of
     the Interpublic Board; and

  .  David A. Bell will become vice-chairman of Interpublic.

forward-looking statements about Interpublic, True North and the combined
company which Interpublic and True North believe are covered by the Private
Securities Litigation Reform Act of 1995. Statements in this document that are
not historical facts are "forward-looking statements" for the purpose of the
safe harbor provided by Section 21E of the Securities Exchange Act of 1934, as
amended, and Section 27A of the Securities Act of 1933, as amended. Forward-
looking statements include:

     North's public filings with the Securities and Exchange Commission,
     which is referred to throughout this document as the Commission;

    .  changes in domestic and foreign laws, regulations and taxes;

    .  changes in competition and pricing environments;

    .  regional or general changes in asset valuations;

    .  the occurrence of significant natural disasters;

    .  general market and industry conditions; and

    .  pricing.

   Moreover, one of Interpublic's business strategies is to acquire businesses
that complement and expand its current business capabilities. Accordingly,
Interpublic is usually engaged in evaluating potential acquisition

                                       17


candidates. Interpublic is currently engaged in a number of preliminary
discussions that may result in one or more substantial acquisitions. These
acquisition opportunities require confidentiality and from time to time give
rise to bidding scenarios that require quick responses by Interpublic. Although
there is uncertainty that any of these discussions will result in definitive
agreements or the completion of any transactions, the announcements of any such
transaction may lead to increased volatility in the trading price of the shares
of Interpublic or delay completion of the merger. The success of recent or
contemplated future acquisitions will depend on the effective integration of
newly-acquired businesses into Interpublic's current activities. Important
factors for integration include realization of anticipated synergies and the
ability to retain new personnel and clients.

   The actual results, performance or achievement by Interpublic, True North or
the combined company could differ materially from those expressed in, or
implied by, forward-looking statements. Accordingly, we cannot assure that any
of the events anticipated by forward-looking statements will occur, or if they
do, what impact they will have on the results of operations and financial
condition of Interpublic, True North or the combined company.

     customers.

                                       19

     Secretary or you must submit a later dated proxy changing your vote.
     Alternatively, you may choose to attend the special meeting and vote in
     person. However, simply attending the meeting will not in itself
     constitute the revocation of your proxy if you do not cast a vote at
     that time. If you do not hold your shares of True North common stock in
     your own name, you may revoke a previously given proxy by following the
     revocation instructions provided by the bank, broker or other party who
     is the registered owner of the shares.

     as instructed.

  .  Costs of Solicitation. True North and Interpublic will each pay one-half
     of the expense of printing and mailing this document. Proxies will be
     solicited through the mail and directly by officers, directors and
     regular employees of True North not specifically employed for such
     purpose, without additional compensation. True North will reimburse
     banks, brokerage houses and other custodians, nominees and fiduciaries
     for their reasonable expenses in forwarding these proxy materials to
     their principals. True North has engaged D.F. King & Company to assist
     it in connection with the solicitation of proxies and will pay D.F. King
     & Company a customary fee for its services and reimburse its expenses.

                                  THE MERGER

Background of the Merger

   The advertising and marketing communications industry has undergone
significant global consolidation in recent years. Consistent with this trend,
over the last several years True North's management and Board observed that
industry participants that achieved greater geographic and functional scale
and brand and services diversity were likely to be at a competitive advantage
relative to smaller competitors and would also be better positioned to take
advantage of long-term growth opportunities and trends.

   In keeping with the industry's trend toward consolidation, in July 1997
True North entered into an agreement to acquire Bozell, Jacobs, Kenyon &
Eckhardt, Inc. In early December 1997, prior to the closing of the Bozell
acquisition, Publicis S.A., a French advertising and marketing communications
company, made a tender offer to purchase approximately 38% of the outstanding
shares of True North common stock at a price of $28.00 per share on the
condition that the Bozell acquisition be terminated. Shortly thereafter, True
North obtained an injunction against interference by Publicis in the Bozell
acquisition and Publicis withdrew its tender offer. True North closed the
acquisition of Bozell on December 30, 1997. The acquisition of Bozell almost
doubled True North's size and added the two agency brands of Bozell Worldwide
and Temerlin McClain LP to complement True North's flagship FCB Worldwide
agency brand. In September 1999, True North restructured its agencies by
transferring specified international operations of Bozell into FCB,
strengthening FCB's global reach and its ability to serve and attract
multinational clients.

   After the Bozell acquisition, True North continued to pursue a program of
targeted acquisitions and completed numerous transactions of smaller relative
size involving a variety of communications services businesses. In addition,
True North's management and Board became increasingly focused on more
significant strategic alternatives available to True North. True North's
management and its Board considered, among other strategies, whether True
North's business and financial performance, and its stockholders, employees
and clients, could benefit from being part of a larger, more diverse company.
Such a combination could offer, among other advantages:

  .  a greater concentration of business outside of North America;

  .  an enhanced ability to attract and serve large, multinational clients;
     and

  .  enhanced diversification in faster growing and higher margin non-
     advertising communications services businesses, such as sales promotion,
     direct marketing, design and branding and business communications
     services.

   As a result, True North's management and its Board began to explore a
variety of alternatives, including:

  .  entering into a significant business combination with one or more major
     advertising and marketing communications firms in a merger among or
     between equals;

  .  entering into a transaction with a global advertising and marketing
     communications firm, with True North as the acquired entity; or

  .  remaining an independent entity and growing through additional
     acquisitions.

   From time to time beginning in 1998 and continuing through early 2001, True
North approached, or was approached by, a substantial number of the other
global advertising and marketing communications firms, including Interpublic,
to discuss significant potential transactions. Many of these expressions of
interest resulted in meetings between representatives of True North and other
parties. In connection with these discussions, True North entered into
confidentiality agreements with some of these other parties, and proprietary
information was supplied by and obtained from True North pursuant to these
confidentiality agreements. True North's management kept its Board apprised of
these developments and, with respect to matters raising material issues, acted
in accordance with the Board's guidance.

                                      21


   In November 1998 and again in March 1999, the chief executive of a global
advertising and marketing communications firm, which we refer to in this
discussion as Company A, made inquiries to True North regarding a possible
business combination with True North. In both instances, the True North Board
determined not to enter into discussions with Company A, and Company A was so
informed.

   In late 1998 and early 1999, True North had preliminary discussions
regarding a possible combination with a global advertising and marketing
communications firm, which we refer to in this discussion as Company B. The
discussions did not advance at that time.

   Commencing in the spring and summer of 1999, True North's management and
Board increased their focus on various strategic initiatives.

   Discussions with Company B regarding a possible business combination resumed
in the late summer and fall of 1999.

   True North management also had discussions with a large private equity firm
about the possibility of taking True North private in a management-led buyout.
However, by September 1999, management ceased considering this type of
transaction due to the growth models and high amount of debt that would be
required to complete it.

   In August 1999, True North entered into discussions regarding a possible
combination with a global advertising and marketing communications firm, which
we refer to in this discussion as Company C. True North and Company C entered
into a confidentiality agreement dated August 26, 1999. During the fall of
1999, discussions continued with both Company B and Company C.

   In February 2000, True North entered into discussions with a global
advertising and marketing communications company, which we refer to in this
discussion as Company D, relating to Company D's possible acquisition of True
North. True North and Company D entered into a confidentiality agreement dated
February 18, 2000 and the chief executive officers and other senior management
of each of True North and Company D held a meeting on February 21, 2000. At
this meeting, the parties discussed, among other matters, whether Company D
would agree to a standstill whereby it would not be permitted to purchase
shares of True North common stock for the duration of negotiations. Company D
indicated that it would agree to such a standstill only if True North would
agree to negotiate exclusively with Company D. True North refused to agree to
an exclusivity provision, and Company D did not enter into a standstill
provision.

   As of February 29, 2000, True North entered into a letter agreement and a
separate indemnification agreement with Morgan Stanley & Co. Incorporated
pursuant to which Morgan Stanley was engaged to act as financial advisor to
True North to explore strategic alternatives with counterparties in the
advertising business. The provisions of the letter agreement relating to fees
payable for Morgan Stanley's services are described under "Opinion of True
North's Financial Advisor" on page 30.

   Over the next several months, members of senior management of True North
held several conversations and meetings with their respective counterparts at
Company D. In addition, during this period True North's management engaged in
wide-ranging discussions with numerous other advertising and communications
services businesses. For instance, True North continued its discussions with
Company C and held meetings and had discussions with representatives of a U.S.
marketing services company, another global advertising and marketing
communications firm, and two media companies. These discussions included
potential transactions of varying structures, including, in certain cases,
possible three-party combinations. Management reported on these discussions to
the True North Board at a meeting held on July 25, 2000.

   In the summer of 2000, members of senior management of True North had a
series of discussions with Company D about a potential transaction. In late
July 2000, Company D presented True North with a preliminary due diligence
request list, and by early August 2000 True North began providing requested

                                       22


information to Company D. On August 16, 2000, the chief executive officers and
other senior officers of each of True North and Company D held a meeting to
review issues raised by these due diligence materials and to discuss other
matters, including the potential for cost savings synergies.

   In late August 2000, True North received an informal indication of interest
from Company D to acquire True North in a stock-for-stock transaction at an
exchange ratio that reflected a price, as of the date of the indication, of
approximately $40 per share of True North common stock. At that time, True
North was reluctant to consider a transaction at this price. At a special
meeting of the True North Board held on September 1, 2000, David Bell, chairman
and chief executive officer of True North, updated the Board on the status of
strategic alternatives then under discussion, including a potential transaction
with Company D. After discussion, the Board advised Mr. Bell to defer further
discussions with Company D so long as the price was inadequate, and Company D
was so informed in a letter from Kevin Smith, executive vice president and
chief financial officer of True North, dated September 5, 2000.

   Contemporaneously, True North renewed discussions with Company B about the
possibility of a combination. The parties explored various means of structuring
a transaction.

   On September 6, 2000, the Chrysler Group of DaimlerChrysler, which at that
time divided its global advertising and marketing communications work between
True North and another global advertising and marketing communications firm,
announced that it would place both of these accounts up for review. The
objective of the review was the consolidation of a substantial portion of
Chrysler Group's advertising and marketing communications services with one
firm on substantially revised business terms.

   At a regular meeting of the True North Board held September 13, 2000, Mr.
Bell and Mr. Smith updated the Board on the status of discussions with Company
D and others regarding a possible merger and the Chrysler account consolidation
review. Representatives of Morgan Stanley, Sidley & Austin (which, on May 1,
2001, became Sidley Austin Brown & Wood), True North's outside legal counsel,
and other outside advisors to True North attended the meeting to assist the
Board in reviewing strategic alternatives. Mr. Bell and Mr. Smith presented an
analysis of the impact on True North's financial results of the two possible
outcomes of the Chrysler account consolidation review --the Chrysler account
being consolidated with either True North or Chrysler's other global
advertising firm-- and a review of the advantages and disadvantages associated
with various potential strategic partners.

   At this meeting, it was reported to the True North Board that, after True
North had deemed Company D's initial indication of interest to be unattractive,
representatives of True North had proposed a pricing structure whereby True
North stockholders would receive initial consideration payable in Company D
stock and, in addition, would receive a separate security which would provide
additional value only if the per share value of Company D's stock did not
appreciate to a specified level following the completion of the transaction.

   A representative of Morgan Stanley then summarized for the True North Board
an estimated range of trading values for True North stock under the two
possible outcomes of the Chrysler account consolidation review. Morgan Stanley
noted that, should True North experience a loss of the Chrysler account, a
potentially significant client conflict issue would be eliminated and, as a
result, several strategic alternatives would become more viable. A
representative of Sidley Austin Brown & Wood then briefed the Board on its
fiduciary duties in considering the several strategic alternatives under
discussion. Following discussion, the Board directed management, with the
assistance of outside advisors, to continue discussions with Company D and
others about a potential strategic transaction.

   After a meeting on September 14, 2000 between senior executives of each of
True North and Company D and their respective advisors, at which little
progress was made with respect to pricing differences, serious discussions
between True North and Company D terminated.

   On November 3, 2000, Chrysler announced that it had completed its account
consolidation review and had determined to consolidate its global advertising
and marketing communications business with its other global advertising and
marketing communications firm, including some of the services previously
provided by True

                                       23


North. In a conference call with analysts, shareholders, the press and others
held on November 6, 2000, Mr. Bell indicated, among other things, that True
North was open to strategic opportunities that would benefit True North's
stockholders and clients and that the elimination of Chrysler as a potential
conflict issue might allow True North to pursue a broader range of these
opportunities.

   True North and Company B, and their advisors, intensified discussions
regarding a potential combination. On November 7, 2000, the chief executive
officers and other senior management of True North and Company B met and
discussed valuation ranges, the Chrysler decision, management and social
issues, timing and the possibility of exclusivity of negotiations. On November
16, 2000, True North entered into a confidentiality agreement with Company B.
Company B prepared a draft merger agreement and provided it to True North on
November 21, 2000. The parties began negotiating the terms of this agreement,
and each party began performing in-depth financial and legal due diligence with
respect to the other.

   The True North Board held a special meeting on November 17, 2000 to consider
the discussions being held by True North's management. A representative of
Sidley Austin Brown & Wood again briefed the Board on its fiduciary duties and
other relevant legal matters. A representative of Morgan Stanley provided a
preliminary evaluation report and a preliminary assessment of the reaction of
the capital markets and potentially interested strategic partners to the
decision of Chrysler with respect to account consolidation. Mr. Bell and
Suzanne Bettman, executive vice president and general counsel of True North,
presented to the Board management's recommendation to continue discussions with
Company B. They also reported that Company B had requested True North to commit
to negotiate exclusively with Company B. After discussion, the Board authorized
senior management to continue negotiations in respect of a strategic
combination transaction with Company B, but determined not to agree to Company
B's request for exclusivity. Furthermore, in consideration of the benefits to
True North of proceeding expeditiously, the Board directed management to report
back to the Board by December 4, 2000.

   The True North Board held another special meeting on November 30, 2000 to
consider the progress of negotiations with Company B. A representative of
Sidley Austin Brown & Wood reported that unresolved issues included the
proposed structure of the transaction, whether the transaction would be treated
as a tax-free reorganization for U.S. federal income tax purposes, the
possibility of True North paying a significant special cash dividend prior to
the closing of the transaction, the treatment of stock options and deferred
compensation obligations, and the proposed management structure and related
social issues. A representative of Morgan Stanley discussed the proposed
funding of the payment by True North of a special dividend prior to closing.
Morgan Stanley also noted that recent movements in share prices of Company B
and True North under the proposed exchange ratio would, as of that time, result
in a below-market transaction price for True North's stockholders. Mr. Bell
then reported to the Board on discussions with other potential strategic
partners. After discussion, the True North Board determined that discussions
with Company B should continue and that management should focus on three issues
in particular:

  .  an Internal Revenue Service ruling confirming that the transaction
     between True North and Company B would qualify as a tax-free
     reorganization for True North's stockholders;

  .  post-transaction management structure; and

  .  further exploration of indications of interest from other interested
     parties.

   On December 9, 2000, the chief executive officers and other senior officers
of each of True North and Interpublic met to discuss the interest of
Interpublic in a strategic transaction with True North. Several additional
conversations followed. On December 15, 2000, True North and Interpublic
entered into a confidentiality agreement and True North began to provide
financial and other information to Interpublic. A face-to-face due diligence
session was scheduled for early January 2001 as a result of these discussions.

   The True North Board held a special meeting on December 15, 2000 to discuss,
among other things, recent meetings with Company B and other potential
strategic partners. Representatives of Sidley Austin Brown & Wood provided the
Board a summary of prior briefings on fiduciary duties, and Morgan Stanley
presented an

                                       24



overview of the proposed structure of the transaction with Company B. Sidley
Austin Brown & Wood reviewed the tax issue previously discussed during the
November 30, 2000 Board meeting, and Morgan Stanley presented a report which
included background and strategic information, pro forma combination analysis,
a proposed timeline and an analysis of the stockholder profiles of True North
and Company B. Upon management's recommendation, and after discussion, the
Board directed management to make continued efforts to reach an agreement with
Company B that would allow an announcement of a transaction by January 15,
2001. The Board also authorized an inquiry to the IRS regarding the tax issue,
completion of a due diligence investigation of Company B, and arrangement for
funding the True North special dividend prior to a transaction.

   In late December 2000, True North and Company C renewed their discussions,
which had been ongoing intermittently since late 1998, relating to a possible
merger transaction between Company C and True North. On December 21, 2000,
Company C conveyed a presentation outlining a possible stock-for-stock
combination that, as of that time, valued True North in the range of $40 to $45
per True North share. Company C requested that True North agree to exclusive
negotiations. True North rejected the request for exclusive negotiations.

   Also in late December 2000, discussions with Company B began to falter.
Company B resisted the request of True North to condition the closing of a
transaction with Company B on obtaining a ruling from the IRS confirming the
tax-free nature of the proposed transaction to True North stockholders. In
addition, pricing, management and structure issues had not been resolved.

   In early January 2001, True North also recommenced discussions with Company
A, with which it had communicated with respect to a potential merger
transaction in late 1998 and again in early 1999. The chief executive officers
and other senior officers of True North and Company A met on January 3, 2001 to
review the business of True North, and True North and Company A entered into a
confidentiality agreement dated January 3, 2001.

   On January 7 and 8, 2001, senior management of True North and of Interpublic
met to review the business of True North and to discuss potential cost-saving
synergies. Senior management of True North and Company C also met to review the
business of True North. Company C, with which True North had previously entered
into a confidentiality agreement, began extensive financial and legal due
diligence on True North in mid-January 2001. A series of meetings between
management of the two companies followed, which continued into mid-February.

   The True North Board held a special meeting on January 12, 2001. Mr. Bell,
together with Mr. Smith and a representative of Morgan Stanley, reviewed for
the Board the status of discussions with each of the four most likely potential
strategic partners with which True North had recently held significant
discussions. It was noted that, although several parties had expressed interest
in a possible transaction, no firm proposal had emerged. Mr. Bell indicated
that discussions were continuing and stated that a more specific update would
be forthcoming at the January 19, 2001 regular Board meeting. At the January
19, 2001 meeting, Mr. Bell and a representative of Morgan Stanley reviewed
recent meetings and developments with respect to potential strategic partners.
The Board encouraged management and True North's advisors to continue
progressing on the various alternatives.

   Between January 16, 2001 and February 7, 2001, a number of meetings occurred
between senior management of True North and of Interpublic to discuss issues
which included potential client conflicts, financial issues, social issues and
potential synergy opportunities.

   During late January and early February 2001, there were a series of
discussions among True North, Company B and Company C to discuss various
potential multiple-party transactions. Ultimately, it was determined that none
of these transactions was feasible under the circumstances.

   On February 4, 2001, the chief executive officers of True North and Company
A met again, and Company A began extensive financial and legal due diligence on
True North in early February 2001.

                                       25


   In mid-February 2001, True North determined to seek the views of the
Securities and Exchange Commission with respect to its accounting treatment for
contingent earn-out payments relating to previously completed acquisitions.
Discussions with Company C were deferred during the pendency of the
Commission's consideration of this issue.

   True North prepared a draft merger agreement and provided it to Company A on
February 15, 2001. During the period between February 15 and February 27, 2001,
legal counsel for each of True North and Company A exchanged comments on the
proposed merger agreement, and meetings and detailed discussions regarding
financial and business issues continued. On February 28, 2001, Company A
submitted to True North a draft bid letter expressing its interest in pursuing
a stock-for-stock transaction valued on that date at approximately $41.50 per
share of True North common stock. Extensive negotiations began on the draft
merger agreement at the end of February 2001 and continued into the beginning
of March 2001. However, as of early March 2001, a number of significant
contractual and management structure issues remained to be resolved with
Company A.

   Senior management of True North and Interpublic continued discussions and
met on February 26, 2001 and again on March 1, 2001. True North provided
Interpublic a draft merger agreement on February 28, 2001. Interpublic engaged
Goldman Sachs & Co. as its financial advisor and began conducting extensive
financial and legal due diligence on True North in early March 2001.

   On February 28, 2001, at a regularly scheduled meeting of the True North
Board, Mr. Bell and a representative of Morgan Stanley reviewed recent meetings
and developments with respect to strategic partners, and the Board discussed
the draft bid letter from Company A.

   In early March 2001, True North announced that the Commission had no
objection to True North's accounting for contingent earn-out payments, however,
True North did agree, in connection with a separate issue raised independently
by the Commission, to change its amortization of intangible assets arising from
acquisitions from up to 40 years to up to 20 years. Consequently, True North
restated financial statements for periods prior to December 31, 2000.

   Following resolution of the Commission review, Company C expressed renewed
interest in pursuing discussions with True North. True North provided Company C
a draft merger agreement on or about March 8, 2001, and a series of meetings
and conversations occurred between True North and Company C representatives
over the following several days.

   On March 9, 2001, Company C presented a non-binding proposal for a stock-
for-stock merger at an exchange ratio that reflected a price as of that date of
$42.00 per share of True North common stock.

   On or about March 12, 2001 each of Interpublic and Company C submitted
comments on the draft merger agreement previously provided to them.

   On March 12, 2001, the True North Board held a special meeting to be updated
on the status of discussions with potential strategic partners. The Board
discussed the various proposals and discussions at length and determined that
additional meetings would be necessary to discuss further developments. Later
that same day, Interpublic submitted to True North a term sheet for a stock-
for-stock merger proposing a fixed exchange ratio to be calculated based upon
the closing price of Interpublic's stock immediately prior to announcement of
the transaction to reflect a value as of the date of such announcement of
$38.50 per share of True North common stock.

   On March 14, 2001, each of Company A, Company C and Interpublic presented a
revised, increased price proposal. Company A's revised proposal was conditioned
upon all outstanding contractual issues being

                                       26


resolved. Interpublic's revised proposal reflected a fixed exchange ratio as of
the date of the proposal, rather than an exchange ratio to be determined
immediately prior to the announcement of a transaction based on a fixed price,
as reflected in Interpublic's original proposal.

   On the afternoon of March 14, 2001, the True North Board held a special
meeting to discuss these three alternative proposals, as follows:

  .  a potential merger transaction with Company A in which True North would
     become a wholly-owned subsidiary of Company A;

  .  a potential merger transaction with Company C in which True North would
     become a wholly-owned subsidiary of Company C; and

  .  a potential merger transaction with Interpublic in which True North
     would become a wholly-owned subsidiary of Interpublic.

   Mr. Bell provided the Board with a detailed update of events since the last
Board meeting. A representative of Morgan Stanley then provided the Board with
preliminary valuation reports, a comparison of shares of common stock versus
American Depositary Receipts (because shares of one or both of Company A and C
are traded in the United States through ADRs representing these shares) and an
assessment of the likely reaction of the capital markets and potentially
interested parties to the various potential transactions. A representative of
Sidley Austin Brown & Wood outlined for the Board the current status of
contractual negotiations with each of the potential strategic partners. Mr.
Bell then presented management's recommendation that True North focus
principally on negotiations with Interpublic. After discussion, the Board
determined that the Interpublic proposal presented the most favorable pricing
and other terms. The Board instructed True North management to focus
principally on negotiations with Interpublic.

   True North and its advisors then continued financial and legal due diligence
on Interpublic and met with Interpublic and its counsel, Cleary, Gottlieb,
Steen & Hamilton, to negotiate final terms of the merger agreement. These
negotiations were essentially completed during the period of March 15 through
March 17, 2001. During this period, Interpublic requested True North to commit
to negotiate exclusively with Interpublic, but True North refused this request.

   On Saturday, March 17, 2001, Interpublic informed True North that the
Interpublic Board had met to evaluate the proposed acquisition of True North
and had approved the merger agreement and the merger contemplated by it.

   On the evening of Sunday, March 18, 2001 the True North Board met for
several hours to evaluate the proposed merger with Interpublic. Sidley Austin
Brown & Wood again briefed the members of the Board on their fiduciary duties.
Morgan Stanley's presentation to the Board, which was based on closing prices
as of March 16, 2001, indicated that the exchange ratios in the most recently
revised price proposals of Company A, Company C and Interpublic reflected
prices, as of that date, of $39.17, $39.57 and $40.24, respectively, per share
of True North common stock. True North's management advised the Board that, in
management's view, a combination between Interpublic and True North would
represent an excellent "fit" from a strategic standpoint, with minimal
conflicts between their respective clients, and would produce a strong and
diversified combined company. True North's management and its advisors made a
lengthy presentation on the results of True North's financial and legal due
diligence investigation of Interpublic.

   Representatives of Morgan Stanley present at the meeting presented a
financial analysis of the proposed transaction and described the basis for
Morgan Stanley's opinion that, as of March 18, 2001, the exchange ratio
pursuant to the proposed merger agreement between True North and Interpublic
was fair from a financial point of view to the holders of shares of True North
common stock. Morgan Stanley then delivered its opinion to the True North
Board. See "Opinion of True North's Financial Advisor" on page 30 and Annex B.

                                       27



   The True North Board, with the assistance of legal counsel, reviewed the
material terms of the proposed business combination, including the more
important provisions of the proposed merger agreement, copies of which had been
supplied to the Board prior to the meeting. The Board further recognized that
the transaction was structured as a tax-free reorganization for U.S. federal
income tax purposes and to qualify for pooling-of-interests accounting
treatment. After careful consideration of all matters, including, among other
things, True North's due diligence investigation of Interpublic, expected
synergies, the expectation of manageable client conflicts, the fact that senior
officers of True North would play a strategic role in the combined companies,
the material terms of the merger agreement and Morgan Stanley's fairness
opinion, the True North Board approved the merger agreement and the merger
contemplated by it. See "Recommendation of the True North Board; Considerations
of the True North Board" on this page 28.

   Late in the evening on March 18, 2001, True North and Interpublic executed
the merger agreement. The following morning, March 19, 2001, True North and
Interpublic issued a joint press release announcing the transaction.

Recommendation of the True North Board; Considerations of the True North Board

   At a special meeting on March 18, 2001, the True North Board determined by
unanimous vote of those present that the merger is advisable, and that the
merger agreement and the merger are in the best interests of True North and its
stockholders. Accordingly, the Board recommends that the stockholders of True
North vote "FOR" adoption of the merger agreement at the special meeting.

   In the course of reaching its decision to approve the merger agreement, the
True North Board consulted with management, as well as with outside legal
counsel and financial advisors, and considered a number of factors, including:

  .  with respect to both True North and Interpublic:

    .  business,

    .  operations,

    .  properties and assets,

    .  financial condition,

    .  competitive position,

    .  business strategy and

    .  prospects and risks involved in achieving prospects,

  .  the nature of the advertising and marketing communications industry in
     which True North competes,

  .  industry conditions,

  .  economic conditions,

  .  market conditions,

  .  the view of the True North Board and management that:

    .  the advertising and marketing communications industry has
       experienced significant consolidation in recent years,

    .  the industry participants that achieve the greatest geographic and
       functional scale and diversity are likely to be at a competitive
       advantage relative to smaller competitors and to be better
       positioned to take advantage of long-term growth opportunities and
       trends and


                                       28


    .  True North's business and financial performance would benefit from
       being part of a larger, more diverse company which would have an
       enhanced capacity to provide sales promotion, direct marketing,
       design and branding and business communication services,

  .  the potential stockholder value that could be expected to be generated
     from the various strategic alternatives available to True North,
     including the alternatives of:

    .  continuing as an independent entity and

    .  entering into a combination with another major advertising and
       marketing communications company,

  .  the fact that the True North Board and management had investigated and
     discussed these strategic alternatives intensively over a period of
     months,

  .  the indications of interest and history of discussions with third
     parties, together with the publicity surrounding interest from third
     parties in engaging in a business combination with True North,

  .  the effect of publicity prior to execution of the merger agreement of a
     potential transaction involving True North on the market price of True
     North common stock which, although not necessarily influencing the True
     North Board's ultimate decision favorably or unfavorably, was considered
     by the True North Board in its deliberations regarding the exchange
     ratio,

  .  the view of the True North Board and management that a combination
     between Interpublic and True North

    .  would represent an excellent "fit" from a strategic standpoint, with
       minimal conflicts between their respective clients and

    .  would produce a strong and diversified combined company,

  .  the synergies, cost reductions and operating efficiencies that should
     become available to the combined enterprise as a result of the merger,
     and the many management challenges associated with successfully
     integrating the business of two major corporations,

  .  the presentations of True North's financial advisor concerning financial
     aspects of the proposed merger and of the various strategic alternatives
     available to True North,

  .  the opinion received from Morgan Stanley that, as of the date of the
     opinion, and based on the considerations in the opinion, the exchange
     ratio pursuant to the merger agreement was fair from a financial point
     of view to the holders of shares of True North common stock,

  .  the current and historical market prices of True North common stock and
     Interpublic common stock relative to each other and relative to those of
     other industry participants, and the relative benefits associated with
     direct stock ownership (as opposed to an American Depositary Receipt
     which offered only indirect stock ownership),

  .  the fact that True North is a personal/professional services business
     and management strongly recommended the merger with Interpublic in view
     of the benefits of the merger to True North's employees and clients,

  .  the facts that several members of True North's current senior management
     team are expected to play a significant role in the management of True
     North during the transition following the merger as well as on an
     ongoing basis and that two current True North directors will be
     appointed to the board of directors of Interpublic,

  .  the expectation that the merger would qualify as a tax-free transaction
     for U.S. federal income tax purposes (except with respect to cash
     received for fractional shares),

  .  the ability to account for the merger as a pooling of interests under
     generally accepted accounting principles,

                                       29


  .  the terms of the merger agreement (including the payment of a
     termination fee if the merger agreement is terminated under specified
     circumstances),

  .  the fact that because the transaction is structured as a merger rather
     than a cash sale, the merger provides True North stockholders with the
     opportunity to participate in a larger, more competitive company,

  .  the lack of availability of appraisal rights in connection with the
     merger and

  .  the fact that the exchange ratio is fixed and, accordingly, the value of
     the transaction could increase or decrease prior to the completion of
     the merger.

   In addition, in considering the proposed merger, the directors of True North
were aware of the interests of certain officers and directors in the merger
described under "Interests of True North's Directors and Management in the
Merger" on page 37.

   The foregoing discussion of the factors considered by the True North Board
is not intended to be exhaustive, but includes the material factors considered
by the Board. In view of the wide variety of factors considered by the Board in
connection with its evaluation of the merger and the complexity of these
matters, the True North Board did not consider it practical, and did not
attempt, to quantify, rank or otherwise assign relative weights to the specific
factors it considered in reaching its decision. The True North Board conducted
a discussion of the factors described above, including asking questions of True
North's management and True North's outside advisors.

   The True North Board reached a unanimous consensus of those present that the
merger was in the best interests of True North and its stockholders. In
considering the factors described above, individual members of the Board may
have given different weights to different factors.

Opinion of True North's Financial Advisor

   Under an engagement letter dated February 29, 2000, True North retained
Morgan Stanley to provide various financial advisory services. In connection
with the engagement, True North requested that Morgan Stanley provide a
fairness opinion in connection with the merger. True North selected Morgan
Stanley to act as True North's financial advisor based on Morgan Stanley's
qualifications, expertise and reputation and its knowledge of the advertising
and marketing communications industry in general and the business and affairs
of True North in particular.

   At a meeting of the True North Board held on March 18, 2001, Morgan Stanley
rendered to the True North Board its oral opinion, subsequently confirmed in
writing, that, as of March 18, 2001, and based upon and subject to the various
considerations, limitations and qualifications set forth in the written
opinion, the exchange ratio pursuant to the merger agreement was fair from a
financial point of view to the holders of shares of True North common stock.

   The full text of the opinion of Morgan Stanley, dated March 18, 2001, is
attached as Annex B. It sets forth, among other things, the assumptions made,
procedures followed, matters considered and limitations on the scope of the
review undertaken by Morgan Stanley in rendering its opinion. True North
stockholders are urged to, and should, read the opinion carefully and in its
entirety.

   Morgan Stanley's opinion is directed to the True North Board and addresses
only the fairness from a financial point of view of the exchange ratio to
holders of shares of True North common stock as of the date of the opinion.
True North stockholders should note that the opinion does not address:

  .  any other aspect of the merger,

  .  True North's underlying business decision to pursue the merger or

  .  the price at which Interpublic common stock will trade following the
     merger or at any other time.

                                       30


   Further, the opinion does not constitute a recommendation to any holder of
shares of True North common stock as to how to vote at the True North
stockholder meeting held in connection with the merger.

   The summary of the opinion of Morgan Stanley set forth below is qualified in
its entirety by reference to the full text of the written opinion, which is
attached as Annex B.

   In connection with rendering its opinion, Morgan Stanley, among other
things:

  .  reviewed publicly available financial statements and other business and
     financial information of True North and Interpublic;

  .  reviewed internal financial statements and other financial and operating
     data concerning True North and Interpublic;

  .  reviewed financial forecasts prepared by the managements of True North
     and Interpublic;

  .  reviewed information relating to strategic, financial and operational
     benefits anticipated from the merger, prepared by the management of True
     North;

  .  discussed the past and current operations and financial condition and
     the prospects of True North, including information relating to
     strategic, financial and operational benefits anticipated from the
     merger, with senior executives of True North;

  .  discussed the past and current operations and financial condition and
     the prospects of Interpublic, including information relating to
     strategic, financial and operational benefits anticipated from the
     merger, with senior executives of Interpublic;

  .  reviewed the pro forma impact of the merger on Interpublic's earnings
     per share, cash flows, consolidated capitalization and financial ratios;

  .  reviewed the reported prices and trading activity for True North common
     stock and Interpublic common stock;

  .  compared the financial performance of True North and Interpublic and the
     prices and trading activity of True North common stock and Interpublic
     common stock with that of other publicly-traded companies comparable
     with True North and Interpublic, and their securities;

  .  reviewed the financial terms, to the extent publicly available, of
     comparable acquisition transactions;

  .  participated in discussions and negotiations among representatives of
     True North and Interpublic and their financial and legal advisors;

  .  reviewed the merger agreement and related documents; and

  .  performed other analyses and considered other factors as Morgan Stanley
     deemed appropriate.

   Morgan Stanley assumed and relied upon, without independent verification,
the accuracy and completeness of the information supplied or otherwise made
available to it by True North and Interpublic for the purposes of its opinion.
With respect to the financial forecasts, including information relating to
strategic, financial and operational benefits anticipated from the merger,
Morgan Stanley assumed that they were reasonably prepared on bases reflecting
the best currently available estimates and judgments of the future financial
performance of True North and Interpublic. In addition, Morgan Stanley assumed
that the merger would be accounted for as a "pooling-of-interests" business
combination in accordance with U.S. generally accepted accounting principles
and the merger would be consummated in accordance with the terms set forth in
the merger agreement, including, among other things, that the merger would be
treated as a tax-free reorganization pursuant to the

                                       31


Internal Revenue Code of 1986. Morgan Stanley also assumed that in connection
with the receipt of all necessary regulatory approvals for the merger, no
restrictions would be imposed that would have a material adverse effect on the
benefits expected to be derived in the merger.

   Morgan Stanley did not make any independent valuation or appraisal of the
assets or liabilities of True North or Interpublic, nor was Morgan Stanley
furnished with any appraisals. Morgan Stanley relied without independent
verification on the assessment of the management of True North and Interpublic
on their ability to retain key clients and employees of True North and
Interpublic. Morgan Stanley's opinion is necessarily based on financial,
economic, market and other conditions as in effect on, and the information made
available to Morgan Stanley as of, the date of its opinion.

   The following is a summary of the material financial analyses performed by
Morgan Stanley in connection with its oral opinion and the preparation of its
written opinion dated March 18, 2001. Some of these summaries of financial
analyses include information presented in tabular format. In order to
understand fully the financial analyses used by Morgan Stanley, the tables must
be read together with the text of each summary. The tables alone do not
constitute a complete description of the financial analyses.

   As described more fully in "Background of the Merger" on page 21, on
November 3, 2000 True North announced that a significant True North client
decided to consolidate selected advertising and marketing services historically
provided by True North with another advertising and marketing services company
which had also provided advertising and marketing services to this client. As a
result, for the purposes of its analyses, Morgan Stanley reviewed financial
forecasts prepared by the management of True North adjusted, as appropriate, to
reflect the financial effects of the consolidation (also known as the Adjusted
True North Management Projections). The Adjusted True North Management
Projections were prepared in March 2001 and reflected management's view as of
that time and were provided to Morgan Stanley for use in its analysis in
connection with the merger. For some of the pro forma combination analyses,
Morgan Stanley used publicly available equity research projections for
Interpublic that Morgan Stanley discussed with Interpublic management (also
known as the Interpublic Projections).

 Historical Common Stock Performance

   Morgan Stanley reviewed the price performance and trading volumes of the
common stock of each of True North and Interpublic from January 1, 1997 through
March 16, 2001. The table below shows the daily high and low closing prices of
True North and Interpublic for that period, compared with a closing price on
March 16, 2001 of $39.31 per share for True North common stock and $35.30 per
share for Interpublic common stock:



                                                         January 1, 1997 through
                                                             March 16, 2001
                                                         -----------------------
                                                            High         Low
                                                         -----------------------
                                                               
      True North........................................ $     52.63 $     17.00
      Interpublic....................................... $     58.06 $     15.83


   Morgan Stanley then compared the price performance of True North to
Interpublic and that of the Standard & Poor's 500 Common Stock Price Index,
which we call the S&P 500 Index, and two groups of selected advertising and
marketing communications companies with publicly-traded common stock. One group
included larger capitalization companies, such as Interpublic, Omnicom Group
Inc. and WPP Group PLC, which we refer to as the Large-Cap Companies, and the
other group included mid-capitalization companies such as Cordiant
Communications Group PLC, Grey Global Group Inc., Havas Advertising and
Publicis Groupe S.A., which we refer to as the Mid-Cap Companies. The Large-Cap
Companies and the Mid-Cap Companies were chosen because they participate in the
global advertising and marketing communications industry and possess financial
and operating characteristics that have similarities to those of True North and
Interpublic. None of the other companies used in this analysis as a comparison
is identical to True North or Interpublic.


                                       32


   This analysis showed that the closing market prices of True North and
Interpublic appreciated during the period from January 1, 1997 through March
16, 2001 as follows:


                                                                       
      True North.........................................................  82.8%
      Interpublic........................................................ 118.9%


   The table below shows the relative stock price appreciation of True North,
the S&P 500 Index and the Large-Cap Companies and Mid-Cap Companies from
January 1, 1997 through March 16, 2001:


                                                                       
      True North.........................................................  82.8%
      S&P 500 Index......................................................  59.2%
      Large-Cap Companies................................................ 188.5%
      Mid-Cap Companies.................................................. 176.6%


 Comparable Company Analysis

   Comparable company analysis examines a company's trading performance
relative to a group of publicly traded peers. Morgan Stanley performed a
comparable public company trading analysis pursuant to which it calculated
price to 2000 and 2001 estimated earnings multiples based on Institutional
Brokers Estimates System (also known as IBES) estimates and the multiple of
aggregate value as of March 16, 2001 to 2001 estimated earnings before
interest, taxes, depreciation and amortization (also known as EBITDA) based on
recent Morgan Stanley equity research estimates for True North. Morgan Stanley
then compared the multiples obtained for True North with multiples obtained
from publicly available information for a group of selected advertising and
marketing communications companies.

   The group of selected advertising and marketing communications companies
included Omnicom, Interpublic, WPP, Cordiant, Havas, True North and Publicis.
Morgan Stanley selected these companies, other than True North, because they
are publicly traded companies with advertising and marketing communications
operations that for purposes of this analysis may be considered similar to
those of True North.

   The analysis showed the following multiples:



                                                                    Aggregate
                                           Price/2000E Price/2001E Value/2001E
                                            Earnings    Earnings     EBITDA
                                           ----------- ----------- -----------
                                                          
     True North...........................    18.5        19.2         8.6
     Group of selected advertising and
      marketing communications companies:
       Low................................    18.5        19.2         8.6
       Median.............................    29.4        23.8         9.9
       High...............................    34.9        30.0        13.6


   Based on an analysis of the comparable companies and the corresponding
information for True North, including the Adjusted True North Management
Projections, Morgan Stanley estimated a per share value for True North common
stock between $38 and $43.

   No company utilized in the comparable company analysis, other than True
North itself, is identical to True North. In evaluating the comparable
companies, Morgan Stanley made judgments and assumptions with regard to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of True
North, including the impact of competition on the business of True North and
the industry generally, industry growth and the absence of any material adverse
change in the financial condition and prospects of True North or the industry
or in the financial markets in general, which could affect the public trading
value of the companies. Mathematical analysis, such as determining the average
or median, is not in itself a meaningful method of using comparable company
data.


                                       33


 Discounted Cash Flow Analysis

   Morgan Stanley estimated the unlevered free cash flows that could be
produced by True North in fiscal years 2001 through 2011, based on a review of
the Adjusted True North Management Projections. Morgan Stanley calculated a
discounted cash flow analysis for True North assuming discount rates ranging
from 9.75% to 10.75%, based on Morgan Stanley's analysis of True North's
weighted average cost of capital, and terminal values for True North by
applying multiples of unlevered EBITDA in the year 2011 from 8.0x to 9.0x. This
analysis produced an implied equity value per share of True North common stock
between approximately $42 and $46.

 Stand-Alone Discounted Equity Value Analysis

   Morgan Stanley calculated the implied present value to holders of shares of
True North common stock of estimated future dividends to be received from True
North and future implied True North stock price based upon the Adjusted True
North Management Projections and assuming an equity discount rate of 10.25% and
2003 price to earnings multiples in a range of 15x to 20x. Morgan Stanley noted
that True North's ratio of stock price to one-year forward earnings had ranged,
over the 1997 to early 2001 period, from 12x-27x, and had been most
consistently in a range of 15x-20x.

   Based on this analysis, Morgan Stanley calculated the present value of
equity, including dividend returns, per share of True North common stock in a
range of approximately $31 to $41.

 Selected Precedent Transactions Analysis

   Using publicly available information, Morgan Stanley reviewed the terms of
selected announced, pending or completed transactions in the advertising
industry. These transactions are:

   The table below presents the high, low and median ratios for these
transactions of aggregate value to each of the last twelve months (also known
as LTM), revenues, EBITDA and earnings before interest and taxes (also known as
EBIT) and equity value to LTM net income.

   Based on the Adjusted True North Management Projections, Morgan Stanley
estimated per share transaction values for True North common stock ranging from
approximately $31 to $52.

   No company or transaction utilized as a comparison in the precedent
transactions analysis is identical to Interpublic, True North or the merger. In
evaluating the precedent transactions, Morgan Stanley made judgments and
assumptions regarding industry performance, general business, economic, market
and financial conditions and other matters, many of which are beyond the
control of True North or Interpublic, including the impact of competition on
True North and the industry in general, industry growth and the absence of any
material adverse change in the financial condition and prospects of True North,
Interpublic or the industry or in the financial markets in general, which could
affect the public trading value of the companies and the aggregate value of the
transactions to which they are being compared. Mathematical analysis (such as
determining the average or median) is not in itself a meaningful method of
using comparable transaction data.

 Exchange Ratio Analysis

   Morgan Stanley reviewed the implied historical exchange ratios for the
shares of common stock of each of True North and Interpublic, determined by
dividing the price per share of True North common stock by the price per share
of Interpublic common stock over the period from January 1, 1997 to March 16,
2001. Morgan Stanley performed this analysis to compare the premium represented
by the exchange ratio with the premium represented by historical exchange
ratios prevailing in the open market. This analysis indicated the following
premiums represented by the average historical exchange ratios prevailing in
the open market:



                     Period Ended                                 Exchange Ratio

     Prior 30 Day Average.........................      1.00            14%


 Relative Contribution Analysis

   Morgan Stanley compared the pro forma contributions of True North and
Interpublic, based on the Adjusted True North Management Projections and the
Interpublic Projections, to the combined company assuming consummation of the
merger. Morgan Stanley observed, among other things, that based on the actual
revenue, EBITDA, EBIT, net income and cash net income for fiscal 2000 for each
company, True North would have contributed between 13.2% and 19.8% to the
combined company's pro forma revenue, EBITDA, EBIT, net income and cash net
income for fiscal 2000. Morgan Stanley also observed, among other things, that
based on the projected revenue, EBITDA, EBIT, net income and cash net income
for each company, True North would contribute between 14.9% and 20.0% to the
combined company's projected revenue, EBITDA, EBIT, net income and cash net
income for fiscal 2001 and 2002. These figures were compared to the pro forma
fully diluted ownership of the combined company by holders of True North common
stock and common stock equivalents of 15.8% implied by the exchange ratio.


                                       35


 Pro Forma Analysis of the Merger

   Morgan Stanley analyzed the pro forma effect of the merger on Interpublic's
estimated earnings per share for the fiscal years ending 2001 through 2003. The
analysis was based on the Adjusted True North Management Projections and the
Interpublic Projections. The analysis assumed the completion of the merger and
included the value of certain benefits of the combination as estimated by the
managements of True North and Interpublic. This analysis indicated that the
impact of the merger on estimated earnings per share of Interpublic common
stock would be modestly accretive (in the range of 1.0% to 1.3%) in each year
during the period (also known as the Pro Forma Interpublic Earnings).

 Observations of Interpublic Valuation on a Stand-Alone and Pro Forma Basis

   Morgan Stanley noted that Interpublic common stock, as of March 16, 2001,
traded at 20.8 times projected one-year forward earnings (also known as P/E)
versus its five-year historical average P/E of 25.3 times and the then current
forward earnings multiples of the other Large-Cap Companies, WPP (24.8x) and
Omnicom (30.0x). Morgan Stanley observed that based upon the Pro Forma
Interpublic Earnings, the exchange ratio and an equity discount rate of 10.25%,
the implied present value of the Interpublic common stock received by holders
of True North common stock in the merger varies based upon Interpublic's future
forward P/E in 2003 as indicated in the table below:



                                                                 Implied Present
                                                                 Value Per True
                                                             P/E   North Share
                                                             --- ---------------
                                                           
     Current Interpublic P/E................................  21     $43.54
     Five Year Average Interpublic P/E......................  25     $51.83


   In connection with the review of the merger by the True North Board, Morgan
Stanley performed a variety of financial and comparative analyses for purposes
of rendering its opinion. The preparation of a fairness opinion is a complex
process and is not necessarily susceptible to a partial analysis or summary
description. In arriving at its opinion, Morgan Stanley considered the results
of all of its analyses as a whole and did not attribute any particular weight
to any particular analysis or factor considered by it. Morgan Stanley believes
that the summary provided and the analyses described above must be considered
as a whole and that selecting any portion of its analyses without considering
all analyses would create an incomplete view of the process underlying its
analyses and opinion. In addition, Morgan Stanley may have given various
analyses and factors more or less weight than other analyses and factors, and
Morgan Stanley may have deemed various assumptions more or less probable than
other assumptions, so that the range of valuations resulting from any
particular analysis described above should not be taken to be Morgan Stanley's
view of the actual value of True North or Interpublic.

   In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of True North or
Interpublic. Any estimates contained in Morgan Stanley's analyses are not
necessarily indicative of future results or actual values, which may be
significantly more or less favorable than those suggested by these estimates.
These analyses were prepared solely as a part of Morgan Stanley's analysis of
the fairness from a financial point of view to the holders of True North common
stock of the exchange ratio pursuant to the merger agreement and were conducted
in connection with the delivery by Morgan Stanley of its opinion to the True
North Board. The analyses do not purport to be appraisals of value or to
reflect the prices at which shares of True North common stock or Interpublic
common stock might actually trade. In addition, as described above, the Morgan
Stanley opinion was one of the many factors taken into consideration by the
True North Board in making its determination to approve the merger. The
exchange ratio and other terms of the merger agreement were determined through
arm's-length negotiations between True North and Interpublic and were approved
by the True North Board. Morgan Stanley did not recommend any specific
consideration to True North or that any specific consideration constituted the
only appropriate consideration for the merger. Consequently, the Morgan Stanley
analyses as described above should not be viewed as determinative of the

                                       36


opinion of the Board with respect to the value of True North common stock or of
whether the True North Board would have been willing to agree to different
consideration.

   Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking and financial
advisory business, is continuously involved in the valuation of businesses and
their securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes. In the course of its trading, brokerage and financing activities,
Morgan Stanley or its affiliates may, at any time, hold long or short positions
in, and buy and sell the debt or equity securities or senior loans of True
North or Interpublic for its account or the account of its customers. Morgan
Stanley and its affiliates have, in the past, provided financial advisory and
financing services to True North and Interpublic and have received fees for the
rendering of these services. Morgan Stanley may also provide investment banking
services to the combined entity in the future.

   True North has agreed to pay Morgan Stanley an advisory fee of approximately
$150,000-$250,000 if the merger is not completed, based primarily on the amount
of time spent on the engagement by Morgan Stanley, an exposure fee of $2.5
million, payable under specified circumstances, and a transaction fee upon
completion of the merger, against which any advisory and exposure fees paid
will be credited, of approximately $10 million.

   True North has also agreed to reimburse Morgan Stanley for any out-of-pocket
expenses incurred by Morgan Stanley in connection with its engagement and to
indemnify Morgan Stanley and its affiliates, their respective directors,
officers, agents and employees and each person, if any, controlling Morgan
Stanley or any of its affiliates against various liabilities and expenses,
including various liabilities under the federal securities laws, related to or
arising out of Morgan Stanley's engagement.

Interests of True North's Directors and Management in the Merger

   Some of the directors and officers of True North have interests in the
merger that are different from, or in addition to, the interests of True North
stockholders generally. These interests, to the extent material, are described
below. The True North board was aware of these interests and considered them,
among other matters, in approving the merger agreement and the merger.

 Options

   The merger agreement provides that, from and after the effective time of the
merger, each outstanding True North stock option will be assumed by Interpublic
and become an option to purchase that number of Interpublic shares determined
by multiplying

  .  the number of shares subject to the True North option immediately prior
     to the effective time of the merger, by

  .  the exchange ratio,

at an exercise price per Interpublic share equal to the exercise price per True
North share immediately prior to the effective time of the merger divided by
the exchange ratio. As of the effective time, each True North option converted
into an Interpublic option will be subject to the same terms and conditions as
were applicable immediately prior to the effective time under the related
option agreement and stock option plan under which it was originally granted.

   Under the terms of the True North stock option plan, the vesting and
exercisability of outstanding True North options will accelerate as a result of
the merger. Under the terms of the True North outside director stock option
plan, the vesting and exercisability of outstanding stock options held by non-
employee directors will not accelerate as a result of the merger. The following
table discloses as of April 30, 2001, for each True

                                       37

officer of True North and is currently a part-time employee, the current chief
financial officer of True North and for all directors and executive officers as
a group, the number of True North shares subject to options that will be
subject to accelerated vesting upon the merger.

 Restricted Stock

   Upon the merger, each outstanding share of restricted True North common
stock will convert into shares of Interpublic common stock and no longer be
subject to restrictions pursuant to its terms. The following table discloses as

 Employment Agreements


   True North has entered into employment agreements with many of its executive
officers (including Messrs. Bell, Kelmenson, Ryan and Smith) that provide,
among other things, for the payment of severance benefits in the event of
termination of the executive's employment under specified circumstances.
Although the

                                       38



availability of severance benefits under these employment agreements is not
automatically triggered upon the occurrence of a change in control, many of
these agreements contain constructive termination provisions that would permit
the executives to leave True North and trigger their severance benefits
(generally comprised of base salary, incentive compensation and other benefits
for up to three years) based upon specified adverse changes in their
employment. These adverse changes generally include a material diminution in
duties and responsibilities, a material adverse change in title, office or
reporting responsibilities, a decrease in base salary and any material change
in the geographic location of the executive's employment. In addition, in Mr.
Ryan's agreement an adverse change also includes the failure to continue to
nominate Mr. Ryan for membership on the board of directors of the publicly-held
company that ultimately controls FCB Worldwide.

   Some benefits in the employment agreements with executive officers of True
North are accelerated in the event an executive's employment terminates under
specified circumstances following a change in control, such as the proposed
merger. For example, Mr. Ryan's employment agreement provides that if he is
terminated without cause or if he terminates his employment for specified
reasons within two years following the merger, the cash portion of his
severance payments would be payable in a lump sum, rather than in periodic
installments. Moreover, the employment agreements for Mr. Bell and Mr. Ryan
each provide that, in the event that severance benefits become payable to him
within two years following the merger, then these severance benefits may be
reduced to the extent necessary to maximize the benefits to him after taking
excise and other taxes into account. The employment agreements for other True
North executive officers contain similar provisions.


 Asset Protection Plan

   True North maintains an Asset Protection Plan for the benefit of specified
key employees (including three executive officers) who are not parties to
employment agreements with True North. The Asset Protection Plan provides for
the payment of severance benefits if the employee's employment terminates under
specified circumstances within 24 months after the adoption of the merger
agreement by the True North stockholders. If during this period the employee's
employment is terminated without cause or the employee resigns due to certain
adverse changes in his or her employment, then the employee will receive a lump
sum severance payment equal to the employee's accrued base salary and a pro
rata bonus for the year of termination, plus a multiple of the employee's
annual base salary and the average of specified prior bonuses, which for the
covered executive officers would be equal to one times their respective base
salaries and average bonuses. The employee would also be entitled to continued
health and life benefits over a specified period of time following termination
of employment, which for the covered executive officers would continue for up
to one year following termination.

 Indemnification and Insurance

   Interpublic has agreed in the merger agreement that all rights under any
organizational documents of True North or any agreement of current and former
directors and officers of True North to indemnification for acts and omissions
before the merger will survive the merger.

   The merger agreement also provides that, for six years following the merger,
Interpublic will maintain directors' and officers' liability insurance coverage
for the directors and officers of True North to the extent currently maintained
by True North or, if less, to the extent available at a cost not to exceed 150
percent of the last annual premium paid prior to March 18, 2001.

 Executive Benefit Trust

   Within seven days after the True North stockholders approve the merger and
at the end of each 12-month period after that date, True North will transfer
cash or life insurance policies into a trust in an amount sufficient to pay,
when due, the administrative expenses of the trust and the benefits that have
accrued under True North's

                                       39


Part-Time Directors Employment Agreement Program, Deferred Variable Incentive
Compensation Program and Deferred Compensation Plan (and related predecessor
deferred compensation plans) pursuant to their terms.

 New Positions at Interpublic

   The merger agreement provides that, on the day of the merger, Mr. Bell and
Mr. Ryan will become members of the Interpublic Board and that Mr. Bell will
become vice chairman of Interpublic.

Anticipated Accounting Treatment

   The merger is expected to qualify as a pooling of interests for accounting
and financial reporting purposes. Under this method of accounting:

  .   the recorded assets and liabilities of Interpublic and True North will
      be carried forward to the combined company at their recorded amounts,
      subject to any adjustments required to conform the accounting policies
      of the companies; and

  .   income of the combined company will include income of Interpublic and
      True North for the entire fiscal year in which the merger occurs.

   Each of Interpublic and True North has agreed that it will do the best it
reasonably can to cause its independent accountants to deliver a letter to the
other relating to the qualification of the merger as a pooling of interests for
accounting purposes. In addition, each of Interpublic and True North has agreed
not to take any action that would prevent or impede the merger from qualifying
as a pooling of interests for accounting and financial reporting purposes. The
receipt of the accountants' "pooling" letters is a condition to the merger that
may be waived by Interpublic, but not by True North.

Regulatory Approvals

   We set forth below a summary of the regulatory clearances and approvals
required to effect the merger. While we believe that we will obtain those
requisite regulatory clearances and approvals for the merger, we cannot assure
you that we will obtain these approvals on satisfactory terms or otherwise.

   United States. The Hart-Scott-Rodino Antitrust Improvements Act and the
rules promulgated under this Act by the Federal Trade Commission require, in
connection with the merger, the provision of notifications and information to
the Antitrust Division of the Department of Justice and the FTC and the
satisfaction of specified waiting period requirements. On April 18, 2001,
Interpublic and True North filed the required pre-merger notification and
report forms with the Antitrust Division and the FTC. The waiting period in
connection with this filing is expected to expire on May 18, 2001, absent an
early termination, extension or request for additional information. We may not
complete the merger until the satisfaction of this waiting period requirement.
Additional filings and clearances under this Act may be required in connection
with the receipt by a True North stockholder of Interpublic stock with a value
in excess of $50 million and the indirect acquisition by Interpublic of a
minority investment held by True North.


   The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions like the merger. At any time before or after
the completion of the merger, the Antitrust Division or the FTC could take any
action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the completion of the merger or
seeking the divestiture of substantial assets of Interpublic or True North.

   Outside the United States. The completion of the merger is also subject to
regulatory clearances and approvals by authorities outside the United States,
consisting primarily of antitrust regulators from the European Union, South
Africa, Canada and Israel.

                                       40



   In addition, we have been advised that we may complete the merger before we
have obtained regulatory approvals and clearances in Colombia, Slovakia and
Turkey so long as we postpone integration and other changes to the operations
of Interpublic and True North in these three jurisdictions until after we have
obtained the applicable approvals and clearances there.

   General. We are not aware of any governmental approvals or actions that may
be required for completion of the merger other than as described above. Should
any other approval or action be required, we currently contemplate that the
approval would be sought or action taken.

   The merger agreement obligates each of Interpublic and True North to
complete the merger only if the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act has terminated or expired and if the companies have
obtained or made all other governmental approvals, clearances and filings that,
if not obtained, would have a material adverse effect or the effect of making
the merger illegal.

   In addition, the merger agreement provides that Interpublic need not agree
to conditions in connection with obtaining regulatory clearances and approvals
if the conditions would have a material and adverse impact on Interpublic, True
North or the benefits that Interpublic would otherwise have derived from the
merger.


   The satisfaction of these regulatory requirements may jeopardize or delay
completion of the merger or may reduce the anticipated benefits of the merger
because governmental authorities may subject the completion of the merger to
compliance with conditions.

Resale of Shares of Interpublic Common Stock

   Shares of Interpublic common stock issuable to True North stockholders upon
completion of the merger will have been registered under the Securities Act.
These securities may be traded freely in the United States without restriction
by those stockholders who are not deemed to be affiliates of Interpublic or
True North for purposes of the rules promulgated under the Securities Act.

   If you are an affiliate of Interpublic or True North as that term is used in
the Securities Act, you may not use this document in connection with any resale
by you of shares of Interpublic common stock that you receive as a result of
the merger.

   True North has agreed in the merger agreement to use its reasonable best
efforts to cause each person who may be deemed to be an affiliate of True North
to execute and deliver to Interpublic a letter in which the person agrees,
among other things, not to sell, transfer, or otherwise dispose of any of the
shares of Interpublic common stock distributed to them in connection with the
merger, including upon exercise of the True North stock options to be assumed
by Interpublic by reason of the merger, except in compliance with Rule 145
under the Securities Act, in a transaction that is otherwise exempt from the
registration requirements of the Securities Act or in an offering registered
under the Securities Act. The letter agreement provides further that the person
may not sell or otherwise reduce his or her risk relative to shares of
Interpublic common stock until Interpublic publishes consolidated financial
results covering at least 30 days of post-merger combined operations of True
North and Interpublic. In addition, the letter agreement prohibits sales,
pledges, transfers or other dispositions of shares of True North common stock
during the 30 days preceding the merger. During the periods described above,
subject to providing written notice to Interpublic and other restrictions, and
to the extent permitted under the pooling of interests accounting rules and
applicable securities laws, affiliates of True North will be permitted to sell
or make charitable contributions or gifts of up to 10% of the shares of
Interpublic common stock received by them or True North common stock owned by
them.

No Appraisal Rights

   Under applicable Delaware law, you will have no appraisal rights in
connection with the merger.

Material U.S. Federal Income Tax Consequences of the Merger

   It is the opinion of Sidley Austin Brown & Wood, counsel to True North, and
of Cleary, Gottlieb, Steen & Hamilton, counsel to Interpublic, that subject to
the accuracy of customary representations made by True North and Interpublic,
and subject to customary assumptions, the merger will qualify as a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code. Accordingly, the following material U.S. federal income tax consequences
will result from the merger:

  .   no gain or loss will be recognized by True North, Interpublic's merger
      subsidiary or Interpublic as a result of the merger;

  .   no gain or loss will be recognized by you when you receive Interpublic
      common stock in exchange for True North common stock in the merger,
      except with respect to cash received in lieu of a fractional share of
      Interpublic common stock;

  .   the tax basis of the Interpublic common stock received by you in the
      merger will be the same as the tax basis of your True North common
      stock surrendered in the merger reduced by the tax basis allocable to
      fractional shares for which cash is received; and

  .   the holding period for Interpublic common stock that you receive in the
      merger will include the holding period of your shares of True North
      common stock if you held the True North common stock as a capital asset
      at the time of the merger.

   The opinions are based on the Internal Revenue Code, U.S. Treasury
regulations, current administrative rulings and practice and judicial
authority, all of which are subject to change, possibly with retroactive
effect. The Internal Revenue Service, which we refer to in this document as the
Service, will not be asked to rule on the tax consequences of the merger.
Instead, True North will rely on the opinion of Sidley Austin Brown & Wood and
Interpublic will rely on the opinion of Cleary, Gottlieb, Steen & Hamilton.
These opinions have been filed with the Commission, and you can obtain copies
of them as described under "Where You Can Find More Information" on page 69. An
opinion of counsel is not binding on the Service and the Service could take a
position different from what is reflected in the opinions. We cannot assure you
that the opinions will be upheld by the courts if challenged by the Service. We
urge you to consult your own tax and financial advisors regarding the U.S.
federal income tax consequences of the merger for you based on your own
particular facts and circumstances as well as any state, local, foreign or
other tax consequences of the merger.

   If you receive cash for any fractional share interest in a share of
Interpublic common stock in the merger, you will be treated as though
Interpublic distributed an actual fractional share interest to you and then
redeemed the fractional share interest for cash. The difference between the
cash amount you will receive for the fractional share interest and the amount
of your tax basis in the True North common stock allocable to that fractional
share interest will generally be capital gain or loss if you hold your True
North common stock as a capital asset at the time of the merger. Capital gains
recognized by an individual holder on capital assets held for more than one
year generally are treated as long-term capital gains, which are subject to a
maximum rate of 20%.

   True North stockholders will be required to retain records and file a
statement setting forth facts relating to the merger with their U.S. federal
income tax returns.

   The treatment of the holder of restricted True North common stock whose
shares convert into shares of Interpublic common stock will depend on whether
the holder made an election under section 83(b) of the Code with respect to the
restricted True North common stock. If a valid section 83(b) election was made,
the holder will have the same treatment in the merger as the holders of
unrestricted True North common stock. If a valid section 83(b) election was not
made, the holder generally will recognize ordinary compensation income upon the
receipt of Interpublic common stock equal to the fair market value on the date
of exchange (plus any cash received in lieu of a fractional share). A holder
who has not made a valid section 83(b) election will be subject

                                       42


to withholding at the applicable federal, state and local rates. A holder who
has not made a valid section 83(b) election will also have a tax basis in the
Interpublic shares equal to their fair market value on the date compensation
income with respect to the shares is recognized and a holding period that
commences on the following day.

   The discussion above summarizes the material U.S. federal income tax
consequences of the merger, but may not address the particular facts and
circumstances of your situation. It does not discuss all of the consequences
that may be relevant to you if you are entitled to special treatment under the
Internal Revenue Code (as are insurance companies, dealers in securities or
currencies, traders in securities electing to mark to market, exempt
organizations, holders that hold True North common stock as part of a hedge,
straddle, constructive sale or conversion transaction or foreign persons).

   The summary set forth above is not a complete analysis of all potential tax
effects of the transactions contemplated by the merger agreement or the merger
itself. For example, the summary does not discuss the tax effects of the
conversion of True North options into Interpublic options. Further, no
information is provided in this document regarding the tax consequences, if
any, of the merger or the exchange of shares in the merger under state, local,
foreign or other tax laws or under proposed changes in applicable tax laws.

New York Stock Exchange Listing of Interpublic Common Stock; De-listing and De-
registration of True North Common Stock

   The listing on the New York Stock Exchange of the shares of Interpublic
common stock to be issued in the merger is a condition to the merger.

   Following the merger, True North common stock will be de-listed from the New
York Stock Exchange and will be de-registered under the Securities Exchange
Act.

                                       43


                              THE MERGER AGREEMENT

   The following is a summary of the material provisions of the merger
agreement. This description is qualified in its entirety by reference to the
merger agreement itself, a copy of which is attached as Annex A to this
document. You should read the merger agreement in its entirety because it is
the primary legal document that governs the merger.

Effective Time of the Merger

   Promptly after the satisfaction or waiver of the conditions to the merger
set forth in the merger agreement, we will file a certificate of merger with
the Secretary of State of Delaware. When this filing has been made, Veritas
Acquisition Corp., a newly formed wholly owned merger subsidiary of
Interpublic, will be merged with and into True North, and the separate
corporate existence of this merger subsidiary will cease. True North will
survive the merger and exist as a wholly owned subsidiary of Interpublic.
Immediately following the merger, the officers of True North at the effective
time of the merger will continue as the officers of True North. The directors
of True North at the effective time of the merger will be those designated by
Interpublic to be directors of its merger subsidiary. In addition, the merger
agreement provides that, on the day of the merger, David A. Bell and J. Brendan
Ryan will become members of the Interpublic Board and David A. Bell will become
vice-chairman of Interpublic.

What True North Stockholders Will Receive in the Merger

   Each share of True North common stock will convert into the right to receive
1.14 shares of Interpublic common stock. This exchange ratio will be adjusted
in the event of any reclassification, stock split or stock dividend with
respect to Interpublic common stock or any change or conversion of Interpublic
common stock prior to the effective time of the merger but will not be adjusted
for any other reason.

True North Stock Options and Deferred Stock Compensation

   Each outstanding True North stock option will become an option to acquire a
number of shares of Interpublic common stock equal to the number of shares
subject to the option multiplied by the exchange ratio, with the exercise price
being adjusted by dividing the exercise price immediately prior to the merger
by the exchange ratio.

   At the effective time of the merger, each nonemployee director of True North
who elected to receive shares of True North common stock pursuant to the True
North deferred stock compensation program will instead receive the number of
shares of Interpublic common stock equal to the product of:

  .   the number of shares of True North common stock that the nonemployee
      director would otherwise be entitled to receive; and

  .   the exchange ratio.

Exchange of True North Common Stock

   Interpublic will authorize Equiserve to act as the exchange agent to handle
the exchange of True North common stock certificates in the merger. Soon after
the closing of the merger, the exchange agent will send to each holder of True
North common stock a letter of transmittal for use in the exchange and
instructions explaining how to surrender certificates to the exchange agent.
Holders who surrender their certificates to the exchange agent, together with a
properly completed letter of transmittal, will receive the appropriate merger
consideration. Holders of unexchanged stock certificates will receive any
dividends payable by Interpublic after the merger only after they surrender
their certificates.

   Interpublic will not issue any fractional shares of its common stock in the
merger. Each holder of True North common stock will instead receive cash equal
to the product of:

                                       44


  .   the per share closing price on the New York Stock Exchange of the
      Interpublic common stock on the date of the effective time of the
      merger; and

  .   the fraction of shares to which the stockholder would otherwise be
      entitled.

   If your True North stock certificates have been lost, stolen or destroyed,
you will only be entitled to obtain Interpublic common stock or other merger
consideration by providing an affidavit of loss and, if required by
Interpublic, posting a bond in an amount sufficient to protect Interpublic
against claims related to your True North certificates.

Covenants and Other Agreements

 Conduct of Business by True North

   True North has agreed that until the merger it will:

  .   conduct its business in the ordinary course;

  .   seek to preserve its business organizations;

  .   seek to keep available the services of its officers and employees;

  .   seek to preserve its relationships with customers, suppliers and others
      with whom it has business relations;

  .   not pay dividends or make distributions other than regular quarterly
      cash dividends consistent with past practice;

  .   not engage in other specified transactions relating to its capital
      stock;

  .   not amend its organizational documents; and

  .   not take any action that would result in its inability to satisfy
      conditions to the merger.

In addition, True North has agreed that until the merger it will not engage in
any of a number of material transactions specified in the agreement.

 Conduct of Business by Interpublic

   Interpublic has agreed that until the merger it will not:

  .   pay dividends or make distributions other than regular quarterly
      dividends consistent with past practice;

  .   liquidate or dissolve itself;

  .   amend its organizational documents in a manner adverse to holders of
      its or True North's common stock; or

  .   take any actions that would result in its inability to satisfy
      conditions to the merger.

 No Solicitation

   True North has agreed in the merger agreement that it will not, and will not
authorize or knowingly allow its subsidiaries or its officers, directors,
representatives or advisors or those of its subsidiaries to:

  .   solicit, initiate or purposefully encourage any takeover proposal;

  .   enter into any agreements with respect to any takeover proposal;

  .   engage in any discussions or negotiations concerning any takeover
      proposal;

                                       47


  .   furnish any information in connection with any takeover proposal;

  .   knowingly facilitate any takeover proposal or inquiries that may lead
      to a takeover proposal;

  .   waive or amend any confidentiality, standstill or similar agreement
      relating to any takeover proposal; or

  .   amend or grant releases or approve any transaction or redeem any rights
      under the Stockholder Rights Plan of True North.

   Under the merger agreement, a takeover proposal is any offer or proposal by
any third party, or any public announcement or filing by any third party that
indicates an intention to make an offer or proposal, regarding any of the
following:

  .   a merger, consolidation, share exchange, recapitalization or other
      business combination involving True North or any of its significant
      subsidiaries; or

  .   the acquisition of a 15% or greater equity interest in, 15% or more of
      the voting securities or capital stock of, or 15% or more of the assets
      of True North or any of its significant subsidiaries.

   However, True North may enter into discussions or negotiations with, or
furnish information to, a third party that makes an unsolicited, bona fide
written takeover proposal if:

  .  after taking into consideration the advice of independent legal counsel,
     the True North Board determines in good faith that these actions are
     necessary for the Board to comply with its fiduciary duties;

  .  the takeover proposal is not subject to any financing contingencies, or
     copies of bona fide customary commitments from reputable financial
     institutions for all necessary financing have been furnished to True
     North;

  .  the True North Board determines in good faith that the takeover proposal
     is reasonably likely to be consummated; and

  .  the True North Board, after consultation with and consideration of the
     advice of an independent, nationally recognized financial advisor,
     determines that the takeover proposal would be more favorable from a
     financial point of view to its stockholders than the merger.

   The merger agreement defines a takeover proposal that satisfies those
criteria as a superior proposal and requires, before the True North Board takes
any action with respect to a superior proposal, that it:

  .  deliver written notice to Interpublic at least two business days before
     True North enters into discussions or negotiations with, or furnishes
     information to, the party making the proposal; and

  .  require the party making the proposal to enter into a customary
     confidentiality agreement.

   Furthermore, if the True North Board decides to enter into discussions or
negotiations with, or furnish information to, a party making a takeover
proposal, then the merger agreement requires True North to:

  .  notify Interpublic of this decision, and furnish Interpublic with the
     material terms of the takeover proposal and the identity of the party
     making the proposal, as promptly as practicable and not later than 48
     hours after this decision by the True North Board; and

  .  provide Interpublic with all material changes to the proposal, and with
     all information furnished to the party making the proposal that True
     North had not previously furnished to Interpublic, as promptly as
     practicable and not later than 48 hours after True North learns of the
     changes or furnishes the information.


                                       48


   True North has also agreed to, and will direct its subsidiaries and its
officers, directors, employees, representatives and advisors to, cease any
activities, discussions or negotiations with any parties other than Interpublic
with respect to any takeover proposal that was ongoing at the time of the
merger agreement.

 Obligation to Recommend

   The True North Board has agreed to recommend to its stockholders the
adoption of the merger agreement. The merger agreement does not permit the True
North Board to withdraw or modify its recommendation unless:

  .  True North has complied with the restrictions on solicitation described
     above;

  .  there is a pending unsolicited bona fide written superior proposal;

  .  after taking into consideration the advice of independent legal counsel,
     the True North Board determines in good faith that this action is
     necessary to comply with its fiduciary duties; and

  .  at least two business days before this action, True North notifies
     Interpublic of its intention and provides Interpublic with the material
     terms of the superior proposal and the identity of the party making the
     superior proposal.

 Expenses

   Whether or not the merger is completed, all expenses incurred in connection
with the merger agreement and the transactions contemplated by the merger
agreement will be paid by the party incurring the expenses, except that the
costs of filing, printing and mailing this document and any other required
regulatory filings will be shared equally by Interpublic and True North and
except as described below under "Termination Fee" on page 51.

 Consents and Approvals

   Interpublic and True North have agreed to use their reasonable best efforts
to make all filings with, and obtain all consents, clearances and approvals
from, regulators and other third parties if required in connection with the
merger, including under U.S. and non-U.S. antitrust laws. In connection with
seeking any approval of a governmental entity, the efforts of Interpublic may
include divesting or holding separate assets or agreeing to governmental
conditions. However, these efforts of Interpublic need not include the
acceptance of conditions or any other actions that would have a material and
adverse impact on Interpublic, True North or the benefits that Interpublic
would otherwise have derived from the merger.

 Indemnification and Insurance

   See "Interests of True North's Directors and Management in the Merger" on
page 37.

 Employee Matters

   Interpublic has agreed to cause True North to honor all its existing
employment, bonus, severance and similar agreements following the merger. In
addition, until at least December 31, 2001, the material benefit plans of True
North, other than equity-based plans, will remain in place. From January 1,
2002 until at least June 30, 2002, employees of True North at the time of the
merger will receive from the combined company benefits, other than equity-based
benefits, that are at least as favorable as those under True North's existing
plans and these employees will be eligible to participate in equity plans of
Interpublic on a substantially equivalent basis as similarly situated employees
of Interpublic. Employees will generally receive credit for their period of
service with True North up to the merger.

   Interpublic has agreed to use reasonable best efforts to cause any
acquisitions of equity securities of Interpublic (including derivative
securities) contemplated by the merger by each individual who becomes a
director or officer of Interpublic to be exempt under Rule 16b-3 under the
Securities Exchange Act of 1934.

its dividend policy will remain unchanged after completion of the merger. The
declaration and payment of dividends after the merger will depend upon
financial covenants in borrowing facilities entered into by Interpublic,
business conditions, operating results, capital and reserve requirements and
the Interpublic Board's consideration of other relevant factors.

                          NOTES TO UNAUDITED PRO FORMA

                    COMBINED CONDENSED FINANCIAL INFORMATION

NOTE 1: PRO FORMA ADJUSTMENTS

  .   The stockholders' equity accounts of Interpublic and True North have
      been adjusted to reflect the issuance of approximately 57 million
      shares of Interpublic common stock in the merger pursuant to an
      exchange ratio of 1.14 shares of Interpublic common stock for each
      share of True North common stock.

  .   The estimated direct costs of the merger will be approximately $30
      million. The pro forma balance sheet gives effect to these direct costs
      as if they had been incurred as of December 31, 2000, but the pro forma
      combined condensed statements of income do not give effect to these
      expenses. The direct costs of the merger consist primarily of fees and
      expenses of investment bankers, attorneys and accountants, together
      with SEC filing fees, financial printing and other fees.

  .   Since accounting policies of the combining companies are substantially
      comparable, we made no adjustments to the unaudited combined condensed
      financial statements to conform accounting policies. Certain
      liabilities in the unaudited combined condensed balance sheet of True
      North have been reclassified to conform to the format used by
      Interpublic.

NOTE 2: PRO FORMA EARNINGS PER SHARE

  .   The pro forma earnings per share has been calculated based on the
      weighted average number of shares of True North common stock adjusted
      to reflect an exchange ratio of 1.14 shares of Interpublic common stock
      for each share of True North common stock.

NOTE 3: RESTRUCTURING AND INTEGRATION COSTS

  .   The amounts presented do not include restructuring or integration costs
      which will be incurred in connection with the merger of True North and
      Interpublic. These costs will be incurred for employee severance,
      office reorganization, investment realignment and other integration-
      related costs. Neither Interpublic nor True North has finalized their
      estimates of the amount and nature of the restructuring and integration
      costs. These amounts will be charged to operations in the appropriate
      periods, and therefore, are not reflected in the unaudited pro forma
      combined condensed financial statements. The unaudited pro forma
      combined condensed financial statements reflect neither the impact of
      these charges nor the benefits to be realized from the expected
      savings.

NOTE 4: FUNDING OF CERTAIN BENEFITS

  .   As required under the terms of a trust established by True North, an
      amount will be contributed to the trust to pay benefits that have
      accrued under specified deferred compensation plans of True North. The
      trust assets will be retained on the balance sheet until the benefits
      are paid. The pro forma adjustment of $36.8 million reflected in the
      pro forma combined condensed balance sheet reflects the amount that
      would have been contributed based on benefits accrued as of December
      31, 2000.

million shares of Interpublic preferred stock without par value.

Common Stock

   General. As of March 30, 2001, 316,434,315 shares of Interpublic common
stock were outstanding. All outstanding shares of Interpublic common stock are
fully paid and non-assessable. Interpublic common stock is traded on the New
York Stock Exchange.

   Certificates. Interpublic common stock is issued in registered form. Every
holder of Interpublic common stock is entitled to a share certificate.

   Dividends. Subject to preferences applicable to any outstanding Interpublic
preferred stock, holders of Interpublic common stock are entitled to receive
ratably such dividends as may be declared by the board of directors of
Interpublic out of funds legally available for this purpose.

   Meetings. Annual meetings of Interpublic stockholders are held each year on
the third Tuesday of May at 11:00 a.m. or on the next succeeding business day.
Written notice must be mailed to each stockholder entitled to vote not less
than ten nor more than 60 days before the date of the meeting. The presence in
person or by proxy of the holders of record of a majority of the issued and
outstanding shares of Interpublic entitled to vote at such meeting constitutes
a quorum for the transaction of business at meetings of the stockholders.
Special meetings of the stockholders may be called for any purpose by the
Interpublic Board and shall be called by the chairman of the Interpublic Board
or the secretary upon a written request, stating the purpose of such meeting,
submitted by a majority of the Interpublic Board or by the holders of a
majority of the outstanding shares of all classes of capital stock entitled to
vote at the meeting.

   Voting Rights. The holders of Interpublic common stock are entitled to one
vote for each share held of record. Holders of Interpublic common stock may
vote by proxy.

   Liquidation, Dissolution or Winding-Up. In the event of a liquidation,
dissolution or winding-up of Interpublic, after payment shall have been made to
holders of any outstanding preferred stock of the full amounts to which they
shall be entitled, the holders of Interpublic common stock are entitled, to the
exclusion of the holders of preferred stock, to share ratably according to the
number of shares held by them in all remaining assets available for
distribution to the holders of Interpublic common stock.

   Transfers. Interpublic's by-laws do not allow the Interpublic Board to
refuse to register transfers of shares.

   Other Rights. Holders of Interpublic common stock have no preemption,
redemption, conversion or other subscription rights.

Preferred Stock

   The Interpublic Board has the authority, without further action by the
Interpublic stockholders, to issue up to 20 million shares of preferred stock,
without par value, in one or more series and to fix the rights, preferences,
privileges and restrictions of such preferred stock, including dividend rights,
conversion rights, voting rights, terms of redemption, liquidation preferences,
and the number of shares constituting any series or

                                       65


the designation of the series. Issuance of Interpublic preferred stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could make it more difficult for a third party to
acquire a majority of the outstanding voting stock of Interpublic. There are
currently no shares of preferred stock issued or outstanding.

            COMPARATIVE RIGHTS OF HOLDERS OF TRUE NORTH COMMON STOCK
                          AND INTERPUBLIC COMMON STOCK

   True North and Interpublic are both Delaware corporations. The rights of
each company's stockholders are generally governed by Delaware law and each
company's certificate of incorporation and by-laws. Upon completion of the
merger, stockholders of True North will become stockholders of Interpublic. No
changes to the Interpublic certificate of incorporation or by-laws will be
adopted in connection with the merger.

   The following is a summary comparison of the provisions governing each
company and a description of some of the differences between the rights of
holders of Interpublic common stock and the rights of holders of True North
common stock. This summary is not a complete discussion of, and is qualified by
reference to, Delaware law, including the Delaware General Corporation Law, the
common and constitutional law of Delaware, and the full texts of the
certificates of incorporation and by-laws of Interpublic and True North.

Annual Meetings of Stockholders

   True North. Annual meetings of True North stockholders are to be held each
year on the second Wednesday of May at a time fixed by the True North Board, on
the next succeeding business day or at any other time determined by the True
North Board.

   Interpublic. Annual meetings of Interpublic stockholders are to be held each
year on the third Tuesday of May or on the next succeeding business day.

Special Meetings of Stockholders

   True North. Special meetings of True North stockholders may be called by the
True North Board, the chief executive officer or the president. The by-laws and
certificate of incorporation of True North do not provide the stockholders of
True North with an opportunity to call a special meeting.

   Interpublic. Special meetings of Interpublic stockholders may be called by
the Interpublic Board. In addition, special meetings of the Interpublic
stockholders shall be called by the chairman of the Board or the secretary upon
a written request, stating the purpose of the meeting, submitted by the holders
of a majority of the outstanding shares of all classes of capital stock
entitled to vote at the meeting.

Action by Consent in Writing of Stockholders

   True North. True North's certificate of incorporation expressly prohibits
action by written consent of its stockholders.

   Interpublic. Interpublic does not limit action by consent in writing of its
stockholders and, as a result, holders of a majority of the outstanding shares
may act by consent in writing without a meeting of stockholders.

Advance Notification of Stockholder Proposals

   True North. A stockholder may only bring business before an annual meeting
of True North stockholders if the secretary has received written notice from
the stockholder not less than 60 days and not more than 90 days before the
annual meeting. Alternatively, if True North has given less than 70 days'
notice of the meeting, then the stockholder may give written notice to the
secretary no later than the tenth day following the day on

                                       66


which True North has given notice of the meeting. Furthermore, the notice by
the stockholder to the secretary must set forth:

  .  a brief description of the business that the stockholder seeks to bring
     before the annual meeting;

  .  a brief description of the reasons for bringing the business before the
     annual meeting;

  .  the name and address of the stockholder;

  .  the number of shares of True North common stock that the holder
     beneficially owns; and

  .  any material interest of the stockholder in the business to be brought
     before the annual meeting.

   Interpublic. The Interpublic by-laws and certificate of incorporation do not
contain limitations on the submission of proposals by stockholders in
connection with scheduled meetings.

Number and Nomination of Directors

   True North. True North's by-laws provide for the Board to set the number of
directors, which may not be less than nine nor more than 21. True North's
certificate of incorporation provides that the number of directors may not be
less than three. True North currently has a 12-member Board.

   Nominations for the election of directors may be made only by the True North
Board or by a committee appointed by the True North Board or by any stockholder
entitled to vote for the election of directors at the applicable meeting
pursuant to a notice timely delivered to the Board. To be timely delivered, the
notice from the stockholder must be received by the secretary of True North not
less than 60 nor more than 90 days before the applicable meeting.
Alternatively, if True North has given less than 70 days' notice of the
meeting, then the stockholder may give written notice to the secretary no later
than the tenth day following the day on which True North has given notice of
the meeting. Furthermore, the notice by the stockholder to the secretary must
include:

  .  a representation that the stockholder is, and will be on the record
     date, a beneficial owner or holder of record of voting stock;

  .  a representation that the stockholder has, and will have on the record
     date, full voting power with respect to its shares of voting stock;

  .  a representation that the stockholder intends to appear in person or by
     proxy at the meeting and to nominate the person or persons specified in
     the notice;

  .  the name and address of the stockholder and the person to be nominated;

  .  a description of all arrangements and understandings between the
     stockholder and each proposed nominee and any other person in connection
     with the proposed nomination;

  .  the number and kinds of securities of True North held by each proposed
     nominee;

  .  information regarding each proposed nominee as would be required by the
     proxy rules promulgated by the Commission; and

  .  a consent from each proposed nominee to serve if elected.

   Interpublic. The Interpublic stockholders or the Interpublic Board sets the
number of directors, which may not be less than three. Interpublic currently
has a ten-member Board. The merger agreement contemplates that, upon the
completion of the merger, the Board will be expanded to include two additional
seats to be occupied by David A. Bell and J. Brendan Ryan.

   The Interpublic by-laws and certificate of incorporation do not contain
limitations on the nomination of directors by stockholders in connection with
scheduled meetings.

Removal of Directors

   True North. Any director may be removed, with or without cause, by the vote
at a stockholders' meeting of the holders of a majority of the shares then
entitled to vote on the election of directors.

   Interpublic. The same provisions for removal apply to the Interpublic Board
except that any director may also be removed for proper cause by the
affirmative vote of at least two-thirds of the entire board of directors.

                                       67


Rights Plan

   True North. In November 1998, the True North Board adopted a Stockholder
Rights Plan by declaring a dividend distribution of one right for each
outstanding share of True North's common stock. The purpose of this plan is to
give the True North Board sufficient time to respond, consistent with its
fiduciary duties, to a takeover attempt. Under the plan, as most recently
amended, if a person or group acquires 15% or more of the outstanding True
North common stock (or, in the case of acquisitions by Publicis, 22% or more),
each right will entitle its holder, excluding the person or group that acquired
15% or more of the outstanding True North common stock, to purchase, at the
right's then-current exercise price, a number of shares of True North common
stock that have a market value of twice the right's exercise price. In the
event that True North is acquired in a merger or other business combination
after a person or group has acquired 15% or more of the outstanding True North
stock (or, in the case of acquisitions by Publicis, 22% or more), each right
will entitle its holder to purchase, at the right's then-current exercise
price, a number of shares of the acquiring company's common stock having a
market value of twice the right's exercise price. The rights are redeemable
under specified circumstances.

   On March 18, 2001, the True North Board amended the plan to exempt the
merger agreement and the merger from triggering any rights under the plan. In
the merger, each right, along with the share of True North common stock with
which it is associated, will convert into Interpublic common stock and, when so
converted, shall no longer be outstanding and shall automatically be canceled
and retired.

   Interpublic. Interpublic does not currently have any agreement or plan in
effect that is similar to the True North Stockholder Rights Plan.

   The validity of the shares of Interpublic common stock offered by this proxy

                          AGREEMENT AND PLAN OF MERGER

   AGREEMENT AND PLAN OF MERGER, dated as of March 18, 2001 (this "Agreement"),
among The Interpublic Group of Companies, Inc., a Delaware corporation
("Parent"), Veritas Acquisition Corp., a Delaware corporation and a direct
wholly owned subsidiary of Parent ("Sub"), and True North Communications Inc.,
a Delaware corporation (the "Company") (Sub and the Company being hereinafter
collectively referred to as the "Constituent Corporations").

                              W I T N E S S E T H:

   WHEREAS, the respective Boards of Directors of Parent, Sub and the Company
have each approved and declared advisable the merger of Sub with and into the
Company (the "Merger"), upon the terms and subject to the conditions set forth
herein, whereby each issued and outstanding share of common stock, par value
$.33 1/3 per share, of the Company ("Company Common Stock") together with the
associated right to purchase one two-thousandth of a share of Series B Junior
Participating Preferred Stock of the Company (the "Rights") under the Rights
Agreement dated November 4, 1998 , as amended, between the Company and First
Chicago Trust Company of New York, a division of Equiserve (the "Rights
Agreement"), not owned directly or indirectly by Parent or the Company will be
converted into shares of Common Stock, par value $.10 per share, of Parent
("Parent Common Stock");

   WHEREAS, the respective Boards of Directors of Parent and the Company have
each determined that the Merger is in furtherance of and consistent with their
respective long-term business strategies and is in the best interest of their
respective stockholders;

   WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code"); and

   WHEREAS, it is intended that the Merger shall be recorded for accounting
purposes as a pooling of interests.

   NOW, THEREFORE, in consideration of the premises, representations,
warranties and agreements herein contained, the parties agree as follows:

                                   ARTICLE I

                                   THE MERGER

   Section 1.1 The Merger. Upon the terms and subject to the conditions hereof,
and in accordance with the Delaware General Corporation Law (the "DGCL"), Sub
shall be merged with and into the Company at the Effective Time (as hereinafter
defined). Following the Merger, the separate corporate existence of Sub shall
cease and the Company shall continue as the surviving corporation (the
"Surviving Corporation") and shall succeed to and assume all the rights and
obligations of Sub in accordance with the DGCL.

   Section 1.2 Effective Time. The Merger shall become effective when a
Certificate of Merger (the "Certificate of Merger"), executed in accordance
with the relevant provisions of the DGCL, is filed with the Secretary of State
of the State of Delaware; provided, however, that, upon mutual consent of the
Constituent Corporations, the Certificate of Merger may provide for a later
date of effectiveness of the Merger not more than 30 days after the date the
Certificate of Merger is filed. When used in this Agreement, the term
"Effective Time" shall mean the date and time at which the Certificate of
Merger is accepted for recording or such later time established by the
Certificate of Merger. The filing of the Certificate of Merger shall be made on
the date of the Closing (as hereinafter defined).

                                       1

                                      A-7


   Section 1.3 Effects of the Merger; Directors and Officers. The Merger shall
have the effects set forth in this Agreement and in Section 259 of the DGCL.

   Section 1.4 Charter and Bylaws; Directors and Officers.

   (a) At the Effective Time, the Amended and Restated Certificate of
Incorporation, as amended, of the Company (the "Company Charter"), as in effect
immediately prior to the Effective Time, shall be amended so that Article
FOURTH of the Company Charter reads in its entirety as follows: "The total
number of shares of all classes of capital stock which the Corporation shall
have authority to issue is 1,000 shares of Common Stock, par value $.01 per
share." As so amended, the Company Charter shall be the Certificate of
Incorporation of the Surviving Corporation until thereafter changed or amended
as provided therein or by applicable law. At the Effective Time, the By-laws of
the Company, as amended (the "Company Bylaws"), as in effect immediately prior
to the Effective Time shall be the Bylaws of the Surviving Corporation until
thereafter changed or amended as provided therein or by the Company Charter and
the DGCL.

   (b) The directors of Sub at the Effective Time of the Merger shall be the
directors of the Surviving Corporation, until the earlier of their resignation
or removal or until their respective successors are duly elected and qualified,
as the case may be. The officers of the Company at the Effective Time of the
Merger shall be the officers of the Surviving Corporation, until the earlier of
their resignation or removal or until their respective successors are duly
elected and qualified, as the case may be.

   (c) As of the Effective Time, Parent's board of directors shall elect David
A. Bell and J. Brendan Ryan as members of the board of directors of Parent, to
hold such office until the earlier of resignation or removal or until their
respective successors are duly elected and qualified.

   (d) As of the Effective Time, Parent's board of directors shall elect David
A. Bell to become the Vice-Chairman of Parent, to hold such office until the
earlier of resignation or removal or until his successor is duly elected and
qualified.

   Section 1.5 Conversion of Securities. As of the Effective Time, by virtue of
the Merger and without any action on the part of Sub, the Company, Parent or
the holders of any securities of the Constituent Corporations:

     (a) Each issued and outstanding share of common stock, par value $.01
  per share, of Sub shall be converted into one validly issued, fully paid
  and nonassessable share of common stock of the Surviving Corporation.

     (b) All shares of Company Common Stock, together with the associated
  Rights, that are held in the treasury of the Company or by any wholly owned
  Subsidiary of the Company and any shares of Company Common Stock, together
  with the associated Rights, owned by Parent (other than shares, if any, in
  trust accounts, managed accounts, custodial accounts and the like that are
  beneficially owned by third parties) shall be canceled and no capital stock
  of Parent or other consideration shall be delivered in exchange therefor.

     (c) Subject to the provisions of Sections 1.8 and 1.10 hereof, each
  share of Company Common Stock issued and outstanding immediately prior to
  the Effective Time, together with the associated Rights, (other than shares
  to be canceled in accordance with Section 1.5(b)) shall be converted into
  1.14 (such number being the "Exchange Ratio") validly issued, fully paid
  and nonassessable shares of Parent Common Stock. All such shares of Company
  Common Stock and the associated Rights, when so converted, shall no longer
  be outstanding and shall automatically be canceled and retired and each
  holder of a certificate representing any such shares shall cease to have
  any rights with respect thereto, except the right to receive any dividends
  and other distributions in accordance with Section 1.7, certificates
  representing the shares of

                                       2

                                      A-8


  Parent Common Stock into which such shares are converted and any cash,
  without interest, in lieu of fractional shares to be issued or paid in
  consideration therefor upon the surrender of such certificate in accordance
  with Section 1.6.

   Section 1.6 Parent to Make Certificates Available.

   (a) Exchange of Certificates. Parent shall authorize Equiserve (or such
other person or persons as shall be reasonably acceptable to Parent and the
Company) to act as Exchange Agent hereunder (the "Exchange Agent"). At or prior
to the Effective Time, Parent shall deposit with the Exchange Agent
certificates representing the shares of Parent Common Stock issuable pursuant
to Section 1.5(c) for exchange with outstanding shares of Company Common Stock,
together with the associated Rights, and cash, as required to make payments in
lieu of any fractional shares pursuant to Section 1.8 (such cash and shares of
Parent Common Stock, together with any dividends or distributions with respect
thereto, being hereinafter referred to as the "Exchange Fund"). The Exchange
Agent shall deliver the Parent Common Stock contemplated to be issued pursuant
to Section 1.5(c) out of the Exchange Fund. The Exchange Agent shall invest any
cash included in the Exchange Fund as directed by Parent on a daily basis and
promptly pay to Parent or its designee any interest or other income resulting
therefrom. Parent shall bear the risk of any investment losses arising from
such investment.

   (b) Exchange Procedures. Parent shall instruct the Exchange Agent, as soon
as practicable after the Effective Time, to mail to each record holder of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock, together with the
associated Rights, converted in the Merger (the "Certificates") a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon actual delivery of the
Certificates to the Exchange Agent, and shall contain instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of Parent Common Stock and cash in lieu of fractional
shares). Upon surrender for cancellation to the Exchange Agent of one or more
Certificates held by any record holder of a Certificate, together with such
letter of transmittal, duly executed, the holder of such Certificate shall be
entitled to receive in exchange therefor (after taking into account all shares
of Company Common Stock then held and surrendered by such holder) a certificate
representing that number of whole shares of Parent Common Stock into which the
shares represented by the surrendered Certificate shall have been converted at
the Effective Time pursuant to this Article I, cash in lieu of any fractional
share in accordance with Section 1.8 and certain dividends and other
distributions in accordance with Section 1.7, and any Certificate so
surrendered shall forthwith be canceled.

   Section 1.7 Dividends; Transfer Taxes; Withholding. No dividends or other
distributions that are declared on or after the Effective Time on Parent Common
Stock, or are payable to the holders of record thereof on or after the
Effective Time, will be paid to any person entitled by reason of the Merger to
receive a certificate representing Parent Common Stock until such person
surrenders the related Certificate or Certificates, as provided in Section 1.6,
and no cash payment in lieu of fractional shares will be paid to any such
person pursuant to Section 1.8 until such person shall so surrender the related
Certificate or Certificates. Subject to the effect of applicable law, there
shall be paid to each record holder of a new certificate representing such
Parent Common Stock: (i) at the time of such surrender or as promptly as
practicable thereafter, the amount of any dividends or other distributions
theretofore paid with respect to the shares of Parent Common Stock represented
by such new certificate and having a record date on or after the Effective Time
and a payment date prior to such surrender; (ii) at the appropriate payment
date or as promptly as practicable thereafter, the amount of any dividends or
other distributions payable with respect to such shares of Parent Common Stock
and having a record date on or after the Effective Time but prior to such
surrender and a payment date on or subsequent to such surrender; and (iii) at
the time of such surrender or as promptly as practicable thereafter, the amount
of any cash payable with respect to a fractional share of Parent Common Stock
to which such holder is entitled pursuant to Section 1.8. In no event shall the
person entitled to receive such dividends or other distributions or

                                       3

                                      A-9


cash in lieu of fractional shares be entitled to receive interest on such
dividends or other distributions or cash in lieu of fractional shares. If any
cash or certificate representing shares of Parent Common Stock is to be paid to
or issued in a name other than that in which the Certificate surrendered in
exchange therefor is registered, it shall be a condition of such exchange that
the Certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange shall pay
to the Exchange Agent any transfer or other taxes required by reason of the
issuance of certificates for such shares of Parent Common Stock in a name other
than that of the registered holder of the Certificate surrendered, or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable. Parent or the Exchange Agent shall be entitled to deduct
and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of Company Common Stock such amounts as
Parent or the Exchange Agent is required to deduct and withhold with respect to
the making of such payment under the Code or under any provision of state,
local or foreign tax law. To the extent that amounts are so withheld by Parent
or the Exchange Agent, such withheld amounts shall be treated for all purposes
of this Agreement as having been paid to the holder of the shares of Company
Common Stock in respect of which such deduction and withholding was made by
Parent or the Exchange Agent.

   Section 1.8 No Fractional Securities. No certificates or scrip representing
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates pursuant to this Article I, and no Parent dividend or
other distribution or stock split shall relate to any fractional share, and no
fractional share shall entitle the owner thereof to vote or to any other rights
of a security holder of Parent. In lieu of any such fractional share, each
holder of Company Common Stock who would otherwise have been entitled to a
fraction of a share of Parent Common Stock upon surrender of Certificates for
exchange pursuant to this Article I will be paid an amount in cash (without
interest), rounded to the nearest cent, determined by multiplying (i) the last
reported sale price per share of Parent Common Stock on The New York Stock
Exchange (the "NYSE") on the date of the Effective Time (or, if the shares of
Parent Common Stock do not trade on the NYSE on such date, the first date of
trading of shares of Parent Common Stock on the NYSE after the Effective Time)
by (ii) the fractional interest to which such holder would otherwise be
entitled. As promptly as practicable after the determination of the amount of
cash, if any, to be paid to holders of fractional share interests, the Exchange
Agent shall so notify Parent, and Parent shall deposit such amount with the
Exchange Agent and shall cause the Exchange Agent to forward payments to such
holders of fractional share interests subject to and in accordance with the
terms of Section 1.7 and this Section 1.8.

   Section 1.9 Return of Exchange Fund. Any portion of the Exchange Fund
(including any income or proceeds thereon or any investments thereof) which
remains undistributed to the former stockholders of the Company for twelve
months after the Effective Time shall be delivered to Parent or its designee,
upon demand of Parent, and any such former stockholders who have not
theretofore complied with this Article I shall thereafter look only to Parent
(subject to abandoned property, escheat and similar laws) for payment of their
claim for Parent Common Stock, any cash in lieu of fractional shares of Parent
Common Stock and any dividends or distributions with respect to Parent Common
Stock. Any such portion of the Exchange Fund remaining unclaimed by holders of
shares of Company Common Stock who are entitled thereto pursuant to Sections
1.7 and 1.8 on the third anniversary of the date of the Effective Time (or such
earlier date as shall be immediately before such date upon which such
securities or amounts would otherwise escheat to or become property of any
public official or Governmental Entity (as hereinafter defined)) shall, to the
extent permitted by law, become the property of Parent, free and clear of
claims or interests of any person previously entitled thereto. Neither Parent
nor the Surviving Corporation shall be liable to any former holder of Company
Common Stock for any such shares of Parent Common Stock, cash, dividends and
distributions which are delivered to a public official or Governmental Entity
pursuant to any applicable abandoned property, escheat or similar law.

   Section 1.10 Adjustment of Exchange Ratio. In the event of any
reclassification, stock split or stock dividend with respect to Parent Common
Stock or any change or conversion of Parent Common Stock into

                                       4

                                      A-10


other securities (or if a record date with respect to any of the foregoing
should occur) prior to the Effective Time, appropriate and proportionate
adjustments, if any, shall be made to the Exchange Ratio, and all references to
the Exchange Ratio in this Agreement shall be deemed to be to the Exchange
Ratio as so adjusted.

   Section 1.11 No Further Ownership Rights in Company Common Stock. All shares
of Parent Common Stock issued upon the surrender for exchange of Certificates
in accordance with the terms hereof (including any cash paid pursuant to
Section 1.8) shall be deemed to have been issued in full satisfaction of all
rights pertaining to the shares of Company Common Stock, together with the
associated Rights, represented by such Certificates.

   Section 1.12 Closing of Company Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of shares
of Company Common Stock shall thereafter be made on the records of the Company.
If, after the Effective Time, Certificates are presented to the Surviving
Corporation, the Exchange Agent or the Parent, such Certificates shall be
canceled and exchanged as provided in this Article I.

   Section 1.13 Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Parent or the Exchange Agent, the posting by such person of a bond, in such
reasonable amount as Parent or the Exchange Agent may direct as indemnity
against any claim that may be made against them with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed Certificate the shares of Parent Common Stock, any cash in lieu of
fractional shares of Parent Common Stock to which the holders thereof are
entitled pursuant to Section 1.8 and any dividends or other distributions to
which the holders thereof are entitled pursuant to Section 1.7.

   Section 1.14 Further Assurances. If at any time after the Effective Time the
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments or assurances or any other acts or things are necessary,
desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation its right, title or interest in, to or under any of
the rights, privileges, powers, franchises, properties or assets of either of
the Constituent Corporations, or (b) otherwise to carry out the purposes of
this Agreement, the Surviving Corporation and its proper officers and directors
or their designees shall be authorized to execute and deliver, in the name and
on behalf of either of the Constituent Corporations, all such deeds, bills of
sale, assignments and assurances and to do, in the name and on behalf of either
Constituent Corporation, all such other acts and things as may be necessary,
desirable or proper to vest, perfect or confirm the Surviving Corporation's
right, title or interest in, to or under any of the rights, privileges, powers,
franchises, properties or assets of such Constituent Corporation and otherwise
to carry out the purposes of this Agreement.

   Section 1.15 Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") and all actions specified in this Agreement to occur
at the Closing shall take place at the offices of Cleary, Gottlieb, Steen &
Hamilton, One Liberty Plaza, New York, New York 10006, at 10:00 a.m. local time
no later than the sixth business day following the day on which the last of the
conditions set forth in Article VI shall have been fulfilled or waived (if
permissible) (other than those conditions that by their nature are to be
satisfied at the Closing, but subject to the fulfillment or waiver (if

                                   ARTICLE II

                REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

   Parent and Sub represent and warrant to the Company as follows:

   Section 2.1 Organization, Standing and Power. Each of Parent and Sub is a
corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction in which it is organized and has the requisite
corporate power and authority to carry on its business as now being conducted.
Each Subsidiary (as hereinafter defined) of Parent is duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
organized and has the requisite corporate power to carry on its business as now
being conducted, except where the failure to be so organized, existing or in
good standing or to have such power or authority would not, individually or in
the aggregate, have a Material Adverse Effect (as hereinafter defined) on
Parent. Parent and each of its Subsidiaries are duly qualified to do business,
and are in good standing, in each jurisdiction where the character of their
properties owned or held under lease or the nature of their activities makes
such qualification necessary, except where the failure to be so qualified would
not, individually or in the aggregate, have a Material Adverse Effect on
Parent. For purposes of this Agreement (a) "Material Adverse Effect" means,
when used with respect to Parent or the Company, as the case may be, any event,
change or effect that individually or when taken together with all other such
events, changes or effects is, or would be, materially adverse to the business,
financial condition or results of operations of Parent and its subsidiaries,
taken as a whole, or the Company and its subsidiaries, taken as a whole, as the
case may be, except to the extent resulting from or relating to (i) any changes
or events affecting the economy of any country or the advertising industry
generally (other than to the extent such changes or events adversely affect
Parent or the Company, as the case may be, in a materially disproportionate
manner in relation to the industry generally) or (ii) the loss of those clients
that have been previously discussed by the parties; and (b) "Subsidiary" means
any corporation, partnership, limited liability company, joint venture or other
legal entity of which Parent or the Company, as the case may be (either alone
or through or together with any other Subsidiary), (i) owns, directly or
indirectly, 50% or more of the stock or other equity interests the holders of
which are generally entitled to vote for the election of the board of directors
or other governing body of such corporation, partnership, limited liability
company, joint venture or other legal entity or otherwise (through contract or
other means) holds or controls 50% or more of the ordinary voting power in
respect of the election or appointment of the board of directors or other
governing body or (ii) of which such party or any of its Subsidiaries is a
general or managing partner.

   Section 2.2 Capital Structure.

   (a) As of the date hereof, the authorized capital stock of Parent consists
of 550 million shares of Parent Common Stock and 20 million shares of preferred
stock, no par value ("Parent Preferred Stock"). At the close of business on
February 28, 2001, (i) 315,527,074 shares of Parent Common Stock were issued
and outstanding, all of which were validly issued, fully paid and nonassessable
and free of preemptive rights and (ii) 5,461,525 shares of Parent Common Stock
were held in treasury of Parent or by Subsidiaries of Parent. As of December
31, 2000, approximately 27,516,000 shares of Parent Common Stock were reserved
for issuance pursuant to outstanding options to purchase shares of Parent
Common Stock under Parent's 1986, 1988, 1996 and 1997 Stock Option Plans
(collectively, the "Parent Stock Plans"). As of the date hereof, the Parent
Stock Plans are the only benefit plans of Parent or its Subsidiaries under
which any securities of Parent are issuable. As of the date of this Agreement,
except as set forth above and except for the issuance of shares of Parent
Common Stock upon exercise of options issued pursuant to the Parent Stock
Plans, no shares of capital stock or other voting securities of Parent were
issued, reserved for issuance or outstanding. All of the shares of Parent
Common Stock issuable in exchange for Company Common Stock at the Effective
Time in accordance with this Agreement will be, when so issued, duly
authorized, validly issued, fully paid and nonassessable and free of preemptive
rights. As of the date of this Agreement, except for (i) this Agreement and
(ii) as set forth above,

                                       6

                                      A-12


and except as disclosed in the Parent SEC Documents (as hereinafter defined),
there are no options, warrants, calls, rights, puts or agreements to which
Parent or any of its Significant Subsidiaries (as hereinafter defined) is a
party or by which any of them is bound obligating Parent or any of its
Significant Subsidiaries to issue, deliver, sell or redeem, or cause to be
issued, delivered, sold or redeemed, any additional shares of capital stock (or
other voting securities or equity equivalents) or convertible or exchangeable
securities of Parent or any of its Significant Subsidiaries or obligating
Parent or any of its Significant Subsidiaries to grant, extend or enter into

subsidiary within the meaning of Rule 1-02 of Regulation S-X of the Securities
and Exchange Commission (the "SEC").

   (b) Each outstanding share of capital stock (or other voting security or
equity equivalent) of each Significant Subsidiary of Parent is duly authorized,
validly issued, fully paid and nonassessable and each such share (or other
voting security or equity equivalent) is owned by Parent or another Subsidiary
of Parent, free and clear of all security interests, liens, claims, pledges,
options, rights of first refusal, agreements, limitations on voting rights,
charges and other encumbrances of any nature whatsoever (collectively, "Liens")
other than such Liens which (individually or in the aggregate) would not have a
Material Adverse Effect on Parent. Except as disclosed in the Parent SEC
Documents, Parent does not have any outstanding bonds, debentures, notes or
other obligations the holders of which have the right to vote (or convertible
into or exercisable for securities having the right to vote) with the
stockholders of Parent on any matter. Exhibit 21 to Parent's Annual Report on
Form 10-K for the year ended December 31, 1999, as filed with the SEC (the

correct statement in all material respects of all of the information required
to be set forth therein by the regulations of the SEC.

of Directors of Parent and Sub have unanimously (i) declared the agreement of

respectively, and their respective stockholders, and (ii) approved and adopted

Company) this Agreement constitutes the valid and binding obligation of Parent
and Sub enforceable against each of them in accordance with its terms. The

promulgated thereunder, the "Securities Act"), for the purpose of registering
the shares of Parent Common Stock to be issued in the Merger (together with any
amendments or supplements thereto, whether prior to or after the effective date
thereof, the "Registration Statement") have been duly authorized by Parent's
Board of Directors.

   Section 2.4 Consents and Approvals; No Violation. Assuming that all
consents, approvals, authorizations and other actions described in this Section
2.4 and in Section 5.7 have been obtained and all filings and obligations
described in this Section 2.4 have been made, and except as set forth in

provisions hereof will not, result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give to others a right of
termination, cancellation or acceleration of any obligation or the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of Parent
or any of its Subsidiaries under, any provision of (i) the Restated Certificate
of Incorporation of Parent (the "Parent Charter") or the By-laws of Parent (the
"Parent Bylaws") or the Certificate of Incorporation or By-laws of Sub, (ii)
any provision of the comparable charter or organization documents of any of
Parent's Subsidiaries, (iii) any loan or credit agreement, note, bond,
mortgage, indenture, lease or other agreement, instrument, permit, concession,

statute, law, ordinance, rule or regulation applicable to Parent or any of its
Subsidiaries or any of their respective properties or assets, other than, in
the case of clauses (ii), (iii) or (iv), any such violations, defaults, rights,
liens, security interests, charges or encumbrances that, individually or in the
aggregate, would not have a Material Adverse Effect on Parent, materially
impair the ability of Parent or Sub to perform their respective obligations
hereunder or prevent the consummation of any of the transactions contemplated
hereby. No filing or registration with, or authorization, consent or approval
of, any domestic (federal and state), foreign or supranational court,

State of Delaware and appropriate documents with the relevant authorities of
other states in which the Company or any of its Subsidiaries is qualified to do

non-U.S. laws of general applicability and (vii) such other consents, orders,
authorizations, registrations, declarations and filings the failure of which to

   Section 4.2 No Solicitation by the Company.

   (a) From the date hereof until the earlier of the Effective Time or the date
on which this Agreement is terminated in accordance with the terms hereof, the
Company shall not, nor shall it authorize or knowingly allow any of its
Subsidiaries to, nor shall it authorize or knowingly allow any officer,
director or employee of or any financial advisor, attorney or other advisor or
representative of, the Company or any of its Subsidiaries to, (i) solicit,
initiate or purposefully encourage the submission of, any Takeover Proposal (as
hereafter defined), (ii) enter into any binding or non-binding agreement with
respect to any Takeover Proposal (other than a confidentiality agreement to the
extent information is permitted to be furnished to any person pursuant to this
Section 4.2(a)), (iii) participate in any discussions or negotiations
regarding, or furnish to any person any information with respect to or in
connection with, or take any other action to facilitate knowingly any inquiries
or the making of any proposal that constitutes, or may reasonably be expected
to lead to, any Takeover Proposal; (iv) amend or grant any waiver or release
under any confidentiality, standstill or similar agreement, in each case
relating to a Takeover Proposal or (v) except as expressly contemplated by this
Agreement with respect to the Merger, amend or grant any waiver or release or

provided, however, that, nothing contained in this Agreement shall prevent the
Company or its Board of Directors from (i) complying with Rules 14d-9 and 14e-2
under the Exchange Act or publicly disclosing the existence of a Takeover
Proposal involving the Company to the extent required by applicable law or (ii)
furnishing non-public information to, or entering into discussions or
negotiations with, any person or entity in connection with an unsolicited bona
fide written Takeover Proposal by such person or entity, if (x) the failure to
take such action would, in the good faith judgment of the Board of Directors of
the Company, taking into consideration the advice of independent legal counsel
of the Company, violate the fiduciary duties of the Board of Directors of the
Company to the Company's stockholders under applicable law, (y) (1) such
Takeover Proposal is not subject to any financing contingencies or complete
copies of executed, bona fide customary commitments from reputable financial
institutions for all necessary financing shall have been furnished to the
Company and (2) the Board of Directors of the Company has determined in good
faith that (A) such Takeover Proposal, if accepted, would be reasonably likely
to be consummated taking into account all legal, financial, regulatory and
other aspects of the proposal and the person making the proposal, and (B) after
consultation with and considering the advice of independent financial advisors
of national standing and after taking into account the strategic benefits to be
derived from the Merger and the long term prospects of Parent and its
Subsidiaries and after consideration of other matters it deems relevant, would,
if consummated, result in a transaction more favorable to the Company's
stockholders from a financial point of view than the Merger (a Takeover
Proposal satisfying such criteria being a "Superior Proposal"), and (z) prior
to furnishing such non-public information to, or entering into discussions or
negotiations with, such person or entity, such Board of Directors receives from
such person or entity an executed confidentiality agreement with provisions not
less favorable to the Company than those contained in the Confidentiality
Agreements (as defined below) and provides at least two full business days'
advance notice to Parent to the effect that it is proposing to take such
action, together with the information required to be provided pursuant to
Section 4.2(b). For purposes of this Agreement, "Takeover Proposal" means any
offer or proposal by any third party (or binding or non-binding agreement by
any third party with the Company with respect to, or any public announcement or
SEC filing by any third party that indicates an intention to make, such an
offer or proposal) (a) for a merger, consolidation, share exchange,
recapitalization or other business combination involving the Company or any of
its Significant Subsidiaries or (b) to acquire in any manner (including by
disposition or transfer), directly or indirectly, a 15% or greater equity
interest in, 15% or more of the voting securities or capital stock of, or 15%
or more of the assets of, the Company or any of its Significant Subsidiaries,
other than the transactions contemplated by this Agreement.

   (b) With respect to any Takeover Proposal as to which the Company proposes
to take any action permitted by clause (ii) of the proviso in Section 4.2(a)
above, the Company shall notify Parent of such Takeover Proposal as promptly as
practicable (but in no case later than 48 hours) after the Company's decision
to take

                                       21

                                      A-27


such action, and shall provide Parent with the material terms of such Takeover
Proposal and the identity of the person making it and all information provided
by the Company to such person in accordance with Section 4.2(a) to the extent
not previously delivered to Parent, and shall thereafter convey to Parent, as
promptly as practicable (but in no case later than 48 hours) after the Company
becomes aware thereof, all material changes to such terms and all additional
information provided by the Company to such person to the extent not previously
delivered to Parent. Subject to Section 4.2(a), immediately after the execution
and delivery of this Agreement, the Company will, and will direct its
Subsidiaries to, and will direct its and their respective officers, directors,
employees, financial advisors, attorneys, other advisors and representatives
to, cease and terminate all existing activities, discussions and negotiations
with any parties conducted heretofore with respect to any possible Takeover
Proposal.

   Section 4.3 Pooling of Interests; Reorganization. During the period from the
date of this Agreement through the Effective Time, unless the other party shall
otherwise agree in writing, none of Parent, the Company or any of their
respective Subsidiaries shall (a) knowingly take or fail to take any action
which action or failure would jeopardize the treatment of the Merger as a
pooling of interests for accounting purposes under accounting rules and the
applicable SEC rules and regulations or (b) knowingly take or fail to take any
action which action or failure would jeopardize the qualification of the Merger
as a reorganization within the meaning of Section 368 of the Code. Between the
date of this Agreement and the Effective Time, Parent and the Company each
shall take, or cause to be taken, all actions reasonably necessary in order for
the Merger to be treated as a pooling of interests for accounting purposes.

                             ADDITIONAL AGREEMENTS

   Section 5.1 Stockholder Meeting. The Company will, as soon as practicable
following the date of this Agreement, duly call, give notice of, convene and
hold a meeting of stockholders (the "Stockholder Meeting") for the purpose of
considering the approval and adoption of the agreement of merger (within the
meaning of Section 251 of the DGCL) contained in this Agreement. The Company
will, through its Board of Directors, recommend to its stockholders approval
and adoption of this Agreement, shall use all reasonable efforts to solicit
such approval by its stockholders and shall not withdraw or modify, or propose
to withdraw or modify, in a manner adverse to Parent such recommendation (or
announce publicly its intention to do so), except if the Company has complied
with Section 4.2, an unsolicited bona fide written Superior Proposal is then-
outstanding, the Company provides at least two full business days' advance
notice to Parent to the effect that it is proposing to take such action,
together with the information required to be provided pursuant to
Section 4.2(b), if applicable, and in the good faith judgment of the Company's
Board of Directors, taking into consideration the advice of independent legal
counsel of the Company, the making of, or the failure to withdraw or modify,
such recommendation would violate the fiduciary duties of such Board of
Directors to the Company's stockholders under applicable law. The Company
agrees to submit this Agreement to its stockholders for approval and adoption
whether or not the Board of Directors of the Company determines at any time
subsequent to the date hereof that this Agreement is no longer advisable and
recommends that the stockholders of the Company reject it and notwithstanding
any Takeover Proposal.

   Section 5.2 Preparation of the Registration Statement and the Proxy
Statement. (a) The Company and Parent shall promptly prepare, and the Company
shall file with the SEC, the Proxy Statement and Parent shall prepare and file
with the SEC the Registration Statement, in which the Proxy Statement will be
included as a prospectus. Each of Parent and the Company shall use its
reasonable best efforts to have the Registration Statement declared effective
under the Securities Act as promptly as practicable after such filing. As
promptly as practicable after the Registration Statement shall have become
effective, the Company shall mail the Proxy Statement to its stockholders.
Parent shall also take any action reasonably required to be taken under any

                                       22

                                      A-28


applicable state securities laws in connection with the issuance of Parent
Common Stock in the Merger (other than qualifying to do business in any
jurisdiction where it is not now so qualified or to file a general consent to
service of process in any jurisdiction), and the Company shall furnish all
information concerning the Company and the holders of Company Common Stock as
may be reasonably requested in connection with any such action. The Company and
Parent shall use reasonable best efforts to cause their accountants and counsel
to deliver necessary or required instruments in connection with the
Registration Statement and the Proxy Statement, including opinions, consents
and certificates. If, at any time prior to the Effective Time, the Company or
Parent shall become aware of any event that is required to be described in an
amendment or supplement to the Registration Statement or the Proxy Statement,
then such party shall promptly so advise the other. Each of the Company and
Parent shall give the other reasonable opportunity to review and comment on any
filing (including amendments and supplements) in connection with the
Registration Statement or the Proxy Statement before so filed and will provide
the other with a copy of each such filing. In addition, each will advise the
other of any comments (oral or written) received from the staff of the SEC in
connection with the Registration Statement or the Proxy Statement.

   (b) The Company shall use all reasonable best efforts to cause to be
delivered to Parent a letter of Arthur Andersen LLP, the Company's independent
auditors, dated a date within two business days before the date on which the
Registration Statement shall become effective (and before the date on which
each posteffective amendment to the Registration Statement shall become
effective) and addressed to Parent, in form and substance reasonably
satisfactory to Parent and customary in scope and substance for letters
delivered by independent public accountants in connection with registration
statements similar to the Registration Statement.

   (c) Parent shall use all reasonable best efforts to cause to be delivered to
the Company a letter of PriceWaterhouseCoopers, Parent's independent auditors,
dated a date within two business days before the date on which the Registration
Statement shall become effective (and before the date on which each
posteffective amendment to the Registration Statement shall become effective)
and addressed to the Company, in form and substance reasonably satisfactory to
the Company and customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements
similar to the Registration Statement.

   Section 5.3 Access to Information. (a) Subject to currently existing
contractual and legal restrictions applicable to the Company or any of its
Subsidiaries, including those in the Confidentiality Agreement, dated December
15, 2000, between Parent and the Company, relating to information provided by
the Company, as amended or supplemented (the "Company Confidentiality
Agreement"), the Company shall, and shall cause each of its Subsidiaries to,
afford to the accountants, counsel, financial advisors and other
representatives of Parent reasonable access to, and permit them to make such
inspections as they may reasonably require of, during normal business hours
during the period from the date of this Agreement through the Effective Time,
all of its properties, books, contracts, commitments and records (including,
without limitation, the work papers of independent accountants, if available
and subject to the consent of such independent accountants).

   (b) Subject to currently existing contractual and legal restrictions
applicable to Parent and any of its Subsidiaries or the Company and any of its
Subsidiaries, as the case may be, including those in the Company
Confidentiality Agreement and the Confidentiality Agreement, dated March 2001,
between the Company and Parent relating to information provided by Parent, as
amended or supplemented (together with the Company Confidentiality Agreement,
the "Confidentiality Agreements"), each of Parent and the Company shall, and
shall cause each of its Significant Subsidiaries to, furnish promptly to the
other (A) a copy of each report, schedule, registration statement and other
document filed by it during such period pursuant to the requirements of federal
or state securities laws and (B) all other information concerning its business,
properties and personnel as the other may reasonably request.

   (c) In addition the Company shall provide Parent, as soon as reasonably
practicable following the delivery to management, such monthly financial
statements and data as are regularly prepared for distribution to

                                       23

                                      A-29


Company management, all of which shall be kept confidential pursuant to the
supplement dated March 9, 2001 to the Company Confidentiality Agreement.

   (d) No investigations pursuant to this Section 5.3 shall affect or be deemed
to modify any representations or warranties hereunder. All information obtained
pursuant to this Section 5.3 shall be kept confidential in accordance with the
Confidentiality Agreements.

   Section 5.4 Compliance with the Securities Act.

   (a) Section 5.4(a) of the Company Letter contains a list identifying all
persons who, at the time of the Stockholder Meeting, may be deemed to be
"affiliates" of the Company as that term is used in paragraphs (c) and (d) of
Rule 145 under the Securities Act and under applicable SEC accounting releases
with respect to pooling of interests accounting treatment (the "Rule 145
Affiliates"). The Company shall use its reasonable best efforts to cause each
person who is identified as a Rule 145 Affiliate in such list to execute and
deliver to Parent within 30 days of the date hereof a written agreement in
substantially the form of Exhibit 5.4(a) hereto (the "Company Affiliate
Letter"). Prior to the Effective Time, the Company shall amend and supplement
Section 5.4(a) of the Company Letter and use its reasonable best efforts to
cause each additional person who is identified as a Rule 145 Affiliate of the
Company to execute the Company Affiliate Letter.

   (b) Section 5.4(b) of the Parent Letter contains a list identifying those
persons who may be affiliates of Parent under applicable SEC accounting
releases with respect to pooling of interests accounting treatment. Parent
shall use its reasonable best efforts to enter into a written agreement in
substantially the form of Exhibit 5.4(b) hereto (the "Parent Affiliate Letter")
within 30 days of the date hereof with each of such persons identified in the
foregoing list. Prior to the Effective Time, Parent shall amend and supplement
Section 5.4(b) of the Parent Letter and use its reasonable best efforts to
cause each additional person who is identified as an affiliate of Parent to
execute the Parent Affiliate Letter.

   Section 5.5 Current NYSE Listing. Each of Parent and the Company shall use
its reasonable best efforts to continue the listing of the Parent Common Stock
and the Company Common Stock on the NYSE during the term of this Agreement to
the extent necessary so that appraisal rights will not be available to
stockholders of the Company under Section 262 of the DGCL.

   Section 5.6 Fees and Expenses.

   (a) Except as provided in this Section 5.6 and Section 5.10, whether or not
the Merger is consummated, all costs and expenses incurred in connection with
this Agreement and the transactions contemplated hereby including, without
limitation, the fees and disbursements of counsel, financial advisors and
accountants, shall be paid by the party incurring such costs and expenses,
provided that all printing expenses and all filing fees payable to Governmental
Entities (including, without limitation, filing fees under the Securities Act,
the Exchange Act and the HSR Act) shall be shared equally by Parent and the
Company.

   (b) Notwithstanding any provision in this Agreement to the contrary, if
(i)(A) this Agreement is terminated by the Company or Parent pursuant to
Section 7.1.(d)(i) or 7.1(e) or by Parent pursuant to Section 7.1(b), (B) a
Takeover Proposal (or the intent to make a Takeover Proposal), whether or not
conditional, was publicly announced or made to the Company or its Board either
publicly or privately or to its stockholders generally by a person or entity
that, together with its affiliates and controlling persons or entities, has
assets of not less than $100 million at any time from and after the date hereof
and on or before the date of the event that gave rise to such termination and
(C) at any time on or before the first anniversary of any such termination a
Third Party Acquisition Event (as defined below) occurs or the Company shall
enter into any letter of intent, agreement in principle, definitive acquisition
agreement or other similar agreement with respect to a Third Party Acquisition
Event or (ii) this Agreement is terminated by Parent pursuant to Section
7.1(f), then, in each case, the Company shall (without prejudice to any other
rights that Parent may have against the Company for a

                                       24

                                      A-30


breach of this Agreement) pay to Parent a fee of $80 million in cash, such
payment to be made promptly, but in no event later than, in the case of clause
(i), the closing of such Third Party Acquisition Event or the signing of such
agreement, as the case may be, or, in the case of clause (ii), the first day
following such termination.

   (c) All payments under this Section 5.6 shall be made by wire transfer of
immediately available U.S. dollar funds to an account designated by Parent.

   (d) The Company acknowledges that the agreements contained in Section 5.6(b)
and (c) are an integral part of the transactions contemplated by this Agreement
and that, without these agreements, Parent would not have entered into this
Agreement; accordingly, if the Company fails to pay any amount when, due
pursuant to Sections 5.6(b) and (c) and, in order to obtain such payment,
Parent brings a suit or action which results in a judgment against the Company,
then the Company shall pay to Parent its costs and expenses (including
attorneys' fees) in connection with such suit or action.

   As used in this Agreement, a "Third Party Acquisition Event" means (i) a
transaction or series of transactions pursuant to which any person or group (as
such term is defined under the Exchange Act), other than Parent or Sub, or any
affiliate thereof ("Third Party"), acquires more than 25% of the equity
securities or voting power of the Company or any of its Significant
Subsidiaries, pursuant to a tender offer or exchange offer or otherwise, (ii) a
merger, consolidation, share exchange or other business combination involving
the Company or any of its Significant Subsidiaries pursuant to which any Third
Party acquires ownership of more than 25% of the outstanding equity securities
or voting power of the Company or any of its Significant Subsidiaries or of the
entity surviving such merger or business combination or resulting from such
consolidation, (iii) any other transaction or series of transactions pursuant
to which any Third Party acquires control of assets of the Company or any of
its Significant Subsidiaries (including, for this purpose, outstanding equity
securities of Significant Subsidiaries of such party) having a fair market
value equal to more than 25% of the fair market value of all the consolidated
assets of the Company and its Subsidiaries, taken as a whole, immediately prior
to such transaction or series of transactions, or (iv) any transaction or
series of transactions pursuant to which any Third Party acquires control of
the Board of Directors of the Company or by which nominees of any Third Party
are elected or appointed to a majority of the seats on the Board of Directors
of the Company.

   Section 5.7 Company Stock Plans. (a) Not later than the Effective Time, each
Company Stock Option which is outstanding immediately prior to the Effective
Time pursuant to a Company Stock Option Plan shall become and represent an
option to purchase the number of shares of Parent Common Stock (a "Substitute
Option") (decreased to the nearest full share) determined by multiplying (i)
the number of shares of Company Common Stock subject to such Company Stock
Option immediately prior to the Effective Time by (ii) the Exchange Ratio, at
an exercise price per share of Parent Common Stock (rounded up to the nearest
cent) equal to the exercise price per share of Company Common Stock immediately
prior to the Effective Time divided by the Exchange Ratio. After the Effective
Time, except as provided above in this Section 5.7, each Substitute Option
shall be exercisable upon the same terms and conditions as were applicable
under the related Company Stock Option immediately prior to or at the Effective
Time. The Company shall, if so requested by Parent, use reasonable best efforts
to obtain any consents that may be required in connection with implementing the
provisions of this Section 5.7 (it being understood that, in connection with
any such consents that may be so required, the Company will have satisfied its
obligation under this Agreement relating thereto if it has used reasonable best
efforts to obtain such consents, whether or not successful) or provide any
notice or take any other similar action reasonably requested in connection
therewith. As soon as reasonably practicable, and in no event later than ten
days after the Effective Time, Parent shall file a registration statement on
Form S-8 (or any successor or other appropriate form) with respect to Parent
Common Stock subject to such Substitute Options, or shall cause such Substitute
Options to be deemed to be issued pursuant to a Parent Stock Plan for which
shares of Parent Common Stock have been previously registered pursuant to an
appropriate registration form.

                                      A-31


   (b) As of the Effective Time, the right of each nonemployee director of the
Company who has elected to receive shares of Company Common Stock pursuant to
the deferred stock compensation program maintained by the Company shall become
and represent a right to receive the number of shares of Parent Common Stock
(decreased to the nearest whole share) determined by multiplying (i) the number
of shares of Company Common Stock which would be issuable to such nonemployee
director if he or she ceased serving as a director immediately prior to the
Effective Time by (ii) the Exchange Ratio. Such shares of Parent Common Stock
shall be issued to such nonemployee director as soon as practicable after the
Effective Time.

   Section 5.8 Reasonable Best Efforts; Pooling of Interests.

   (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use reasonable best efforts to take,
or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties in doing, all things necessary,
proper or advisable to consummate and make effective, in the most expeditious
manner practicable, the Merger and the other transactions contemplated by this
Agreement, including, but not limited to: (i) obtaining all necessary actions
or non-actions, waivers, consents and approvals from all Governmental Entities
and the making of all necessary registrations and filings (including filings
with Governmental Entities) and taking all reasonable steps (subject to clause
(c) below, including, in the case of Parent, divesting or holding separate any
assets or agreeing to any governmental conditions), as may be necessary to
obtain an approval or waiver from, or to avoid an action or proceeding by, any
Governmental Entity (including those in connection with the HSR Act), (ii)
obtaining all necessary consents, approvals or waivers from third parties,
(iii) defending any lawsuits or other legal proceedings, whether judicial or
administrative, challenging this Agreement or the consummation of the
transactions contemplated hereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed, (iv) each of Parent and the Company agreeing to take,
together with their respective accountants, all actions reasonably necessary in
order to obtain a favorable determination (if required) from the SEC that the
Merger may be accounted for as a pooling of interests in accordance with
generally accepted accounting principles and (v) the execution and delivery of
any additional instruments reasonably necessary to consummate the transactions
contemplated by this Agreement. No party to this Agreement shall consent to any
voluntary delay of the consummation of the Merger at the behest of any
Governmental Entity without the consent of the other parties to this Agreement,
which consent shall not be unreasonably withheld.

   (b) Each party shall use all reasonable best efforts to not take any action,
or enter into any transaction, which would cause any of its representations or
warranties contained in this Agreement to be untrue in any material respect or
result in a material breach of any covenant made by it in this Agreement or
which could reasonably be expected to impede, interfere with or prevent in any
material respect the Merger.

   (c) Notwithstanding anything herein to the contrary, Parent shall not be
obligated (i) to enter into any "hold-separate" agreement or other agreement
with respect to the disposition of any assets or businesses of the Parent or
any of its Subsidiaries or the Company or any of its Subsidiaries (if such
agreements would, individually or in the aggregate, have a material and adverse
impact on the business of Parent or the Company or on the benefits that would
have otherwise been derived by Parent from the Merger or if such agreement
would impose or give rise to any of the conditions of the type described in
clause (ii) below with the impact described in clause (ii) below) in order to
obtain clearance from the Federal Trade Commission or the Antitrust Division of
the Department of Justice or any other antitrust or competition authorities to
proceed with the consummation of the transactions contemplated hereby or (ii)
to consummate the transactions contemplated hereby in the event that both (A)
any consent, approval or authorization of any Governmental Entity obtained or
sought to be obtained in connection with this Agreement is conditioned upon the
imposition of any restrictions upon (or the making of any accommodation
(financial or otherwise) in respect of the transactions contemplated hereby or)
the conduct of the business of the Surviving Corporation or of Parent or its
Subsidiaries (including any agreement not to compete in any geographic area or
line of business) or results, or

                                       26

                                      A-32


would result in, the abrogation or diminishment of any authority or license
granted by any Governmental Entity and (B) such restrictions, accommodations
and abrogations would, individually or in the aggregate, have a material and
adverse impact on the business of Parent or the Company or on the benefits that
would otherwise have been derived by Parent from the Merger. Parent's exercise
of its rights under this paragraph (c) shall not in any way prejudice the
rights of Parent under this Agreement in respect of Closing conditions and
termination rights.

   Section 5.9 Public Announcements. Parent and the Company will not issue any
press release with respect to the transactions contemplated by this Agreement
or otherwise issue any written public statements with respect to such
transactions without prior consultation with the other party, except as may be
required by applicable law or by obligations pursuant to any listing agreement
with any national securities exchange or the rules of the NYSE.

   Section 5.10 Real Estate Transfer and Gains Tax. Parent and the Company
agree that either the Company or the Surviving Corporation will pay any state
or local tax which is attributable to the transfer of the beneficial ownership
of the Company's or its Subsidiaries' real property, if any (collectively, the
"Gains Taxes"), and any penalties or interest with respect to the Gains Taxes,
payable in connection with the consummation of the Merger. The Company and
Parent agree to cooperate with the other in the filing of any returns with
respect to the Gains Taxes, including supplying in a timely manner a complete
list of all real property interests held by the Company and its Subsidiaries
and any information with respect to such property that is reasonably necessary
to complete such returns. The portion of the consideration allocable to the
real property of the Company and its Subsidiaries shall be determined by Parent
in its reasonable discretion.

   Section 5.11 State Takeover Laws. If any "fair price," "business
combination" or "control share acquisition" statute or other similar statute or
regulation shall become applicable to the transactions contemplated hereby,
Parent and the Company and their respective Boards of Directors shall use their
reasonable best efforts to grant such approvals and take such actions as are
necessary so that the transactions contemplated hereby and thereby may be
consummated as promptly as practicable on the terms contemplated hereby and
thereby and otherwise act to minimize the effects of any such statute or
regulation on the transactions contemplated hereby.

   Section 5.12 Indemnification; Directors and Officers Insurance.

   (a) From and after the Effective Time, Parent shall, and shall cause the
Surviving Corporation to, indemnify and hold harmless all past and present
officers, directors, employees and agents of the Company and of its
Subsidiaries to the full extent such persons are currently indemnified by the
Company for acts or omissions occurring at or prior to the Effective Time
pursuant to the Company Charter, the Company Bylaws and any existing
agreements. Without limiting the generality of the foregoing, in the event any
person entitled to indemnification under this Section 5.12(a) becomes involved
in any claim, action, proceeding or investigation after the Effective Time,
Parent shall, or shall cause the Surviving Corporation to, periodically advance
to such person his or her reasonable legal and other reasonably incurred
expenses (including the cost of any investigation and preparation incurred in
connection therewith), subject to such person providing an undertaking to
reimburse all amounts so advanced in the event of a final nonappealable
determination by a court of competent jurisdiction that such person is not
entitled thereto.

   (b) Parent shall provide, or shall cause the Surviving Corporation to
provide, for an aggregate period of not less than six (6) years from the
Effective Time, the Company's current directors and officers an insurance and
indemnification policy that provides coverage for events occurring on or prior
to the Effective Time (the "D&O Insurance") that is substantially similar (with
respect to limits and deductibles and scope) to the Company's existing policy
or, if substantially equivalent insurance coverage is unavailable, the best
available

                                       27

                                      A-33


coverage; provided, however, that the Parent and the Surviving Corporation
shall not be required to pay an annual premium for the D&O Insurance in excess
of 150% of the last annual premium paid prior to the date of this Agreement.

   (c) The provisions of this Section 5.12 are intended for the benefit of, and
shall be enforceable by, each person entitled to indemnification under this
Section 5.12, his or her heirs and his or her personal representatives.

   Section 5.13 Notification of Certain Matters. Parent shall use its
reasonable best efforts to give prompt notice to the Company, and the Company
shall use its reasonable best efforts to give prompt notice to Parent, of: (i)
the occurrence, or non-occurrence, of any event of which it is aware and which
would be reasonably likely to cause any representation or warranty contained in
this Agreement to be untrue or inaccurate in any material respect, or (ii) any
failure of Parent or the Company, as the case may be, to comply in a timely
manner with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder; provided, however, that the delivery of any
notice pursuant to this Section 5.13 shall not limit or otherwise affect the
remedies available hereunder to the party receiving such notice.

   Section 5.14 Employee Benefit Plans and Agreements.

   (a) From the Effective Time through December 31, 2001, Parent shall cause
the Company and its Subsidiaries to continue to maintain the material benefit
plans and programs provided to employees of the Company and its Subsidiaries
immediately prior to the Effective Time (excluding any such plans (or any
portion of any such plan) providing for equity-related benefits) and subject to
the requirements of applicable law; provided, however, that the performance
criteria under any such plan or program that provides for performance-based
incentive compensation shall be modified or adjusted appropriately to reflect
the transactions contemplated by this Agreement and prevent a change in the
incentive compensation opportunities thereunder. For a period of not less than
six months following December 31, 2001, Parent shall cause to be provided, to
employees of the Company or its Subsidiaries as of the Effective Time
(including each such person who is on vacation, temporary layoff, approved
leave of absence, sick leave or short or long-term disability) (collectively
the "Company Employees"), employee benefits (excluding for this purpose equity-
related benefits) that are, in the aggregate, at least as favorable as those
benefits provided to such Company Employees immediately prior to the Effective
Time and such Company Employees shall be eligible to participate in equity
plans of Parent on a substantially equivalent basis as similarly situated
employees of Parent and its affiliates. Nothing herein shall require the
Company or its Subsidiaries to make matching or profit-sharing contributions in
Company Common Stock under the Company Retirement Plan. For purposes of
vesting, eligibility to participate and benefit accrual (other than accrual
under a defined benefit pension plan) under the employee benefit plans of
Parent and its Subsidiaries providing benefits to any Company Employees after
the Effective Time (collectively the "New Plans"), each Company Employee shall
be credited with his or her years of service with the Company and its
Subsidiaries before the Effective Time, to the same extent as such Company
Employee was entitled, before the Effective Time, to credit for such service
under any similar Company benefit plan in which such Company Employee
participated or was eligible to participate immediately prior to the Effective
Time; provided that the foregoing shall not apply to the extent that its
application would result in a duplication of benefits or for newly established
plans and programs in which employees of Parent and its Subsidiaries
participate and for which prior service of employees of Parent and its
Subsidiaries is not taken into account. In addition, without limiting the
generality of the foregoing: (i) each Company Employee shall be immediately
eligible to participate, without any waiting time, in any and all New Plans to
the extent coverage under such New Plans replaces coverage under a comparable
Company employee benefit plan or compensation arrangement or agreements in
which such Company Employee participated immediately before the Effective Time
(collectively the "Old Plans") and (ii) for purposes of each New Plan providing
medical, dental, pharmaceutical and/or vision benefits to any Company Employee,
Parent shall cause all pre-existing condition exclusions of such New Plans to
be waived for such employee and his or her

                                       28

                                      A-34


dependents, unless such conditions would not have been waived under the
comparable plans of the Company and its Subsidiaries in which such employee
participated or in which such employee would have been eligible to participate
immediately prior to the Effective Time and Parent shall cause any eligible
expenses incurred by such employee and his or her covered dependents during the
portion of the plan year of the Old Plan ending on the date of such employee's
participation in the corresponding New Plans to be taken into account under
such New Plan for purposes of satisfying all deductible, coinsurance and
maximum out-of-pocket requirements applicable to such employee and his or her
covered dependents for the applicable plan year as if such amounts had been
paid in accordance with such New Plan.

   (b) Except as otherwise provided by this Section, nothing in this Agreement
shall be interpreted as limiting the power of the Surviving Corporation to
amend or terminate any particular Company Plan or any other particular employee
benefit plan, program, agreement or policy or as requiring the Surviving
Corporation to offer to continue the employment of any employee (other than as
required by the terms of any written employment contract or benefit plan).

   (c) Parent shall take all reasonable steps to ensure that (i) the
obligations of the Company or the Surviving Corporation to fund the Company's
Executive Benefit Trust (the "Rabbi Trust") within seven days after the
approval of the Merger by the stockholders of the Company shall be honored,
provided that if the Effective Time does not occur within this seven-day
period, the Company shall be entitled to fund such obligations, and that (ii)
the obligations of the Company or the Surviving Corporation under the Rabbi
Trust shall be honored following the Effective Time.

   (d) From the Closing, Parent shall cause to be honored by the Company, the
Surviving Corporation and their Subsidiaries all employment agreements, bonus
agreements, severance agreements and any other similar agreements with the
persons who are directors, officers and employees of the Company and its
Subsidiaries.

   Section 5.15 Section 16(b). The Parent shall use reasonable best efforts to
cause, before the Effective Time, any acquisitions of equity securities of
Parent (including derivative securities) contemplated by this Agreement by each
individual who becomes a director or officer of Parent to be exempt under Rule
16b-3 promulgated under the Exchange Act.

                                   ARTICLE VI

  declarations or approvals of, or filings with, or terminations or
  expirations of waiting periods imposed by, any Governmental Entity, which
  the failure to obtain, make or occur would have the effect of making the
  Merger or any of the

                                       29

                                      A-35


  transactions contemplated hereby illegal or would have, individually or in
  the aggregate, a Material Adverse Effect on Parent (assuming the Merger had
  taken place) or on the Company, shall have been obtained, shall have been
  made or shall have occurred.

     (e) Registration Statement. The Registration Statement shall have become
  effective in accordance with the provisions of the Securities Act. No stop
  order suspending the effectiveness of the Registration Statement shall have

  over the Company or Parent, or any of their respective Subsidiaries, shall
  have enacted, issued, promulgated, enforced or entered any law, rule,

  temporary, preliminary or permanent) which is then in effect and has the
  effect of making the Merger or any of the transactions contemplated hereby
  illegal.

   Section 6.2 Conditions to Obligation of the Company to Effect the
Merger. The obligation of the Company to effect the Merger shall be subject to
the fulfillment at or prior to the Effective Time of the following additional

  certain date) and each of the representations and warranties that is not so
  qualified shall be true and correct in all material respects on and as of
  the Effective Time as if made on and as of such date (other than

  Officer to such effect.

     (b) Tax Opinion. The Company shall have received an opinion of its

  purposes, the shareholders of the Company will recognize no gain or loss
  upon the conversion of their shares of Company Common Stock into shares of

     In rendering such opinion, Sidley & Austin may rely upon representations
  contained herein and may receive and rely upon representations from Parent,
  the Company, and others, including representations from Parent

  attached to the Parent Letter and representations from the Company

  which the failure to obtain such consents and approvals would not,
  individually or in the aggregate, have a Material Adverse Effect on Parent
  (assuming the Merger has taken place).

be in form and substance reasonably satisfactory to the Parent.

                                  ARTICLE VII

                       TERMINATION, AMENDMENT AND WAIVER

   Section 7.1 Termination. This Agreement may be terminated at any time prior
to the Effective Time, whether before or after any approval of the matters
presented in connection with the Merger by the stockholders of the Company:

     (a) by mutual written consent of Parent and the Company;

     (b) by either Parent or the Company if the other party shall have failed
  to comply in any material respect with any of its covenants or agreements
  contained in this Agreement required to be complied with prior to the date
  of such termination, which failure to comply has not been cured within
  thirty business days following receipt by such other party of written
  notice from the non-breaching party of such failure to comply (it being
  understood (i) that any breach of Section 4.2 or 5.1 shall be considered
  material for purposes of this Section 7.1(b) and (ii) that a breach of
  Section 4.2 or the penultimate sentence of Section 5.1 is not capable of
  cure and therefore the 30-day cure period shall not apply in the case of
  any such breach);

     (c) by either Parent or the Company if there has been (i) a breach by
  the other party (in the case of Parent, including any breach by Sub) of any
  representation or warranty that is not qualified as to materiality which
  has the effect of making such representation or warranty not true and
  correct in all material respects or (ii) a breach by the other party (in
  the case of Parent, including any breach by Sub) of any representation or
  warranty that is qualified as to materiality, in each case which breach has
  not been cured within thirty business days following receipt by the
  breaching party from the non-breaching party of written notice of the
  breach;

     (d) by Parent or the Company if: (i) the Merger has not been effected on
  or prior to the close of business on the 180th day after the date hereof
  (provided that if either Parent or the Company determines that additional
  time is necessary in connection with obtaining any consent, registration,
  approval, permit or authorization required to be obtained from any
  Governmental Entity, such date may be extended by Parent or the Company
  from time to time by written notice to the other party to a date not beyond
  the 270th day after the date hereof if the extending party in good faith
  believes that such consent, registration, approval, permit or authorization
  can be obtained by such date); provided, however, that the right to
  terminate this Agreement pursuant to this Section 7.1(d)(i) shall not be
  available to any party whose failure to fulfill any of its obligations
  contained in this Agreement has been the cause of, or resulted in, the
  failure of the Merger to have occurred on or prior to the aforesaid date;
  or (ii) any court or other Governmental Entity having jurisdiction over a
  party hereto shall have issued an order, decree or ruling or taken any
  other action permanently enjoining, restraining or otherwise prohibiting
  the consummation of the Merger and such order, decree, ruling or other
  action shall have become final and nonappealable;

     (e) by Parent or the Company if the stockholders of the Company do not
  approve and adopt the agreement of merger (within the meaning of Section
  251 of the DGCL) contained in this Agreement at the Stockholder Meeting or
  at any adjournment or postponement thereof; provided, however, that the
  Company may not terminate this Agreement pursuant to this Section 7.1(e) if
  the Company has not complied with its obligations under Sections 4.2, 5.1
  and 5.2 or has otherwise breached in any material respect its obligations
  under this Agreement in any manner that could reasonably have caused the
  failure of the stockholder approval to be obtained at the Stockholder
  Meeting; or

     (f) by Parent if (without regard to whether or not a breach of this
  Agreement has occurred) (i) the Board of Directors of the Company shall not
  have recommended, or shall have resolved not to recommend, or shall have
  adversely qualified, adversely modified or withdrawn its recommendation of
  the Merger or declaration that the Merger is advisable and fair to and in
  the best interest of the Company and

                                       32

                                      A-38


  its stockholders, or shall have resolved to do so (even if permitted by
  Section 5.1), (ii) any person (other than Parent or its affiliates)
  acquires or becomes the beneficial owner of 15% or more of the outstanding
  shares of Company Common Stock, (iii) the Board of Directors of the Company
  shall have recommended to the stockholders of the Company any Takeover
  Proposal involving the Company or shall have resolved to do so or (iv) a
  tender offer or exchange offer for 15% or more of the outstanding shares of
  capital stock of the Company is commenced, and the Board of Directors of
  the Company fails, within 10 business days of such commencement, to
  recommend against acceptance of such tender offer or exchange offer by its
  stockholders (including by taking no position with respect to the
  acceptance of such tender offer or exchange offer by its stockholders).

   The right of any party hereto to terminate this Agreement pursuant to this
Section 7.1 shall remain operative and in full force and effect regardless of
any investigation made by or on behalf of any party hereto, any person
controlling any such party or any of their respective officers or directors,
whether prior to or after the execution of this Agreement.

   Section 7.2 Effect of Termination. In the event of termination of this
Agreement by either Parent or the Company, as provided in Section 7.1, this
Agreement shall forthwith become void and there shall be no liability hereunder
on the part of the Company, Parent, Sub or their respective officers or
directors (except for the Confidentiality Agreements and the entirety of
Section 5.6, which shall survive the termination); provided, however, that
nothing contained in this Section 7.2 shall relieve any party hereto from any
liability for any willful breach of a representation or warranty contained in
this Agreement or the breach of any covenant contained in this Agreement.

   Section 7.3 Amendment. This Agreement may be amended by the parties hereto,
by or pursuant to action taken by their respective Boards of Directors, at any
time before or after approval of the matters presented in connection with the
Merger at the Stockholder Meeting, but, after any such approval, no amendment
shall be made which by law requires further approval by such stockholders
without such further approval. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto.

   Section 7.4 Waiver. At any time prior to the Effective Time, the parties
hereto may (i) extend the time for the performance of any of the obligations or
other acts of the other parties hereto, (ii) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (iii) waive compliance with any of the agreements or
conditions contained herein which may legally be waived. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in an instrument in writing signed on behalf of such party.

acceptable manner in order that the transactions contemplated by this Agreement

Board of Directors
True North Communications Inc.
101 East Erie Street
Chicago, Illinois 60611

Members of the Board:

   We understand that True North Communications Inc. ("True North" or the
"Company"), The Interpublic Group of Companies, Inc. ("IPG"), and Veritas
Acquisition Corp., a wholly-owned subsidiary of IPG ("Merger Sub") have entered
into an agreement and plan of merger dated March 18, 2001 (the "Agreement")
which provides, among other things, for the merger (the "Merger") of Merger Sub
with and into True North. Pursuant to the Merger, among other things, True
North will become a wholly-owned subsidiary of IPG and each outstanding share
of True North common stock, par value $.33 1/3 per share, together with the
associated right to purchase one two-thousandth of a share of Series B Junior
Participating Preferred Stock of the Company (collectively, the "True North
Common Stock"), not owned directly or indirectly by IPG or the Company, will be
converted into the right to receive 1.14 (the "Exchange Ratio") shares of IPG
Common Stock, par value $.10 ("IPG Common Stock"). The terms and conditions of
the Merger are more fully set forth in the Agreement.

   You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Agreement is fair from a financial point of view to the holders of shares
of True North Common Stock (other than IPG and its affiliates).

   For purposes of the opinion set forth herein, we have, among other things:

  (a) reviewed certain publicly available financial statements and other
      business and financial information of the Company and IPG,
      respectively;

  (b) reviewed certain internal financial statements and other financial and
      operating data concerning the Company and IPG, respectively;

  (c) reviewed certain financial forecasts prepared by the management of the
      Company and IPG, respectively;

  (d) reviewed information relating to certain strategic, financial and
      operational benefits anticipated from the Merger, prepared by the
      management of the Company;

  (e) discussed the past and current operations and financial condition and
      the prospects of the Company, including information relating to certain
      strategic, financial and operational benefits anticipated from the
      Merger, with senior executives of the Company;

  (f) discussed the past and current operations and financial condition and
      the prospects of IPG, including information relating to certain
      strategic, financial and operational benefits anticipated from the
      Merger with senior executives of IPG;

  (g) reviewed the pro forma impact of the Merger on IPG's earnings per
      share, cash flows, consolidated capitalization and financial ratios;

  (h) reviewed the reported prices and trading activity for True North Common
      Stock and IPG Common Stock;

  (i) compared the financial performance of the Company and IPG and the
      prices and trading activity of True North Common Stock and IPG Common
      Stock with that of certain other publicly-traded companies comparable
      with the Company and IPG, respectively, and their securities;

                                      B-1


  (j) reviewed the financial terms, to the extent publicly available, of
      certain comparable acquisition transactions;

  (k) participated in discussions and negotiations among representatives of
      the Company and IPG and their financial and legal advisors;

  (l) reviewed the Agreement and certain related documents; and

  (m) performed such other analyses and considered such other factors as we
      have deemed appropriate.

   We have assumed and relied upon without independent verification the
accuracy and completeness of the information supplied or otherwise made
available to us by the Company and IPG for the purposes of this opinion. With
respect to the financial forecasts, including information relating to certain
strategic, financial and operational benefits anticipated from the Merger, we
have assumed that they have been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the future financial
performance of the Company and IPG. In addition, we have assumed that the
Merger will be accounted for as a "pooling-of-interests" business combination
in accordance with U.S. Generally Accepted Accounting Principles and the Merger
will be consummated in accordance with the terms set forth in the Agreement,
including, among other things, that the Merger will be treated as a tax-free
reorganization pursuant to the Internal Revenue Code of 1986. We have also
assumed that in connection with the receipt of all necessary regulatory
approvals for the proposed Merger, no restrictions will be imposed that would
have a material adverse effect on the benefits expected to be derived in the
Merger. We have not made any independent valuation or appraisal of the assets
or liabilities of the Company, nor have we been furnished with any such
appraisals. We have relied without independent verification on the assessment
of the management of the Company and IPG on their ability to retain key clients
and employees of the Company and IPG. Our opinion is necessarily based on
financial, economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.

   We have acted as financial advisor to the Board of Directors of the Company
in connection with this transaction and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services for the Company and IPG and have
received fees for the rendering of these services. In the ordinary course of
our businesses, we and our affiliates may actively trade the debt and equity
securities of the Company and IPG for our account or for the accounts of
customers and, accordingly, we or our affiliates may at any time hold long or
short positions in such securities.

   It is understood that this letter is for the information of the Board of
Directors of the Company only and may not be used for any other purpose without
our prior written consent, except that this opinion may be included in its
entirety in any filing made by the Company in respect of the transaction with
the Securities and Exchange Commission so long as this opinion is reproduced in
such filing in full and any description of or reference to us or summary of
this opinion and the related analyses in such filing is in a form acceptable to
us and our counsel. In addition, this opinion does not in any manner address
the prices at which IPG Common Stock will trade at any time, including
following consummation of the Merger, and Morgan Stanley expresses no opinion
or recommendation as to how the stockholders of the Company should vote at the
stockholders' meeting held in connection with the Merger.

   Based on and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Agreement is fair from a
financial point of view to the holders of shares of True North Common Stock
(other than IPG and its affiliates).

                                          Very truly yours,

                                          MORGAN STANLEY & CO. INCORPORATED

                                               /s/ Francis J. Oelerich III

Item 20. Indemnification of Directors and Officers

   Section 145 of Title 8 of the General Corporation Law of the State of
Delaware ("GCL") gives a corporation power to indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation)
by reason of the fact that such person is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding, provided that such director, officer, employee or agent acted in
good faith and in a manner reasonably believed to be in or not opposed by the
best interests of the corporation, and, with respect to any criminal action or
proceeding, provided that such director, officer, employee or agent had no
reasonable cause to believe his or her conduct was unlawful. The same Section
also gives a corporation power to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the corporation to procure a judgment in its
favor by reason of the fact that such person is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner reasonably believed to be in or not
opposed to the best interests of the corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation,
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper. Section 145
of the GCL further provides that, to the extent that a director, officer,
employee or agent of a corporation has been successful on the merits or
otherwise in defense of any such action, suit or proceeding, or in defense of
any claim, issue or matter therein, he or she shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection therewith.

   The Registrant's by-laws contain specific authority for indemnification by
the Registrant of current and former directors, officers, employees or agents
of the Registrant on terms that have been derived from Section 145 of Title 8
of the GCL.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

     (1) to file, during any period in which offers or sales are being made,
  a post-effective amendment to this Registration Statement:

       (i) to include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;

       (ii) to reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than 20 percent change in
    the maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective Registration Statement;

       (iii) to include any material information with respect to the plan
    of distribution not previously disclosed in this Registration Statement
    or any material change to such information in the Registration
    Statement;

     (2) that, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof;

     (3) to remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering;

     (4) that, for purposes of determining any liability under the Securities
  Act of 1933, each filing of the registrant's annual report pursuant to
  Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where
  applicable, each filing of an employee benefit plan's annual report
  pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
  incorporated by reference in the Registration Statement shall be deemed to
  be a new registration statement relating to the securities offered therein,
  and the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof;

     (5) that prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this Registration
  Statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other items
  of the applicable form;

     (6) that every prospectus: (i) that is filed pursuant to paragraph (5)
  immediately preceding, or (ii) that purports to meet the requirements of
  Section 10(a)(3) of the Act and is used in connection with an offering of
  securities subject to Rule 415, will be filed as a part of an amendment to
  the Registration Statement and will not be used until such amendment is
  effective, and that, for purposes of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof;

     (7) insofar as indemnification for liabilities arising under the
  Securities Act of 1933 may be permitted to directors, officers and
  controlling persons of the registrant pursuant to the foregoing provisions,
  or otherwise, the registrant has been advised that in the opinion of the
  Securities and Exchange Commission

                                      II-3


  such indemnification is against public policy as expressed in the Act and
  is, therefore, unenforceable. In the event that a claim for indemnification
  against such liabilities (other than the payment by the registrant of
  expenses incurred or paid by a director, officer or controlling person of
  the registrant in the successful defense of any action, suit or proceeding)
  is asserted by such director, officer or controlling person in connection
  with the securities being registered, the registrant will, unless in the
  opinion of its counsel the matter has been settled by controlling
  precedent, submit to a court of appropriate jurisdiction on the question
  whether such indemnification by it is against public policy as expressed in
  the Act and will be governed by the final adjudication of such issue;

     (8) to respond to requests for information that is incorporated by
  reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this
  Form, within one business day of receipt of such request; and to send the
  incorporated documents by first class mail or other equally prompt means.
  This includes information contained in documents filed subsequent to the
  effective date of the Registration Statement through the date of responding
  to the request; and

     (9) to supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in the Registration Statement when
  it became effective.

                                      II-4



   Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-4 and has duly caused this Amendment No. 1 to
the Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in The City of New York, State of New York, on the
9th day of May, 2001.

                                          The Interpublic Group Of Companies,
