$66.33 and less than or equal to $89.73 during the 20-day period.

     This summary highlights some of the information from this proxy
statement/prospectus and may not contain all of the information that is
important to you. To understand the merger better and for a more complete
description of the legal terms of the merger, you should read this entire
document carefully, including the annexes and other documents to which we have
referred you. See "Additional Information -- Where You Can Find More

THE COMPANIES

Illinois Tool Works Inc.
3600 West Lake Avenue
Glenview, Illinois 60025-5811
Telephone: (847) 724-7500
website: http://www.itwinc.com

     Illinois Tool Works is a multinational manufacturer of highly engineered
products and specialty systems with five business segments. Illinois Tool Works
serves primarily the automotive, construction and general industrial markets.

Premark International, Inc.
1717 Deerfield Road
Deerfield, Illinois 60015
Telephone: (847) 405-6000
website: http://www.premarkintl.com

     Premark is a multinational company that conducts its business through three
business segments: the food equipment group, the decorative products group and
the consumer products group. Premark markets premium products in more than 100
countries under leading brand names such as Hobart, Wilsonart, West Bend,
Florida Tile and Precor.

     In this proxy statement/prospectus, we refer to Illinois Tool Works,
Premark and their subsidiaries after the merger as the "combined company."

WHAT PREMARK STOCKHOLDERS WILL RECEIVE IN THE MERGER

     Upon completion of the merger, each share of Premark common stock will be
converted into and become exchangeable for a fraction of a share of Illinois
Tool Works common stock based on the average closing price of Illinois Tool
Works common stock over the 20-day trading period ending on the second business
day before the effective time of the merger.

     Premark stockholders will receive Illinois Tool Works common stock with a
market value of $55 for each share of Premark common stock so long as the
average closing price of Illinois Tool Works common stock is greater than or
equal to $66.33 and less than or equal to $89.73 during the 20-day period. The
$55 of implied market value represents over a 60% premium above the $34.25
closing price of Premark common stock on the day we announced the transaction.

     If the average closing price of Illinois Tool Works common stock is less
than $66.33 or greater than $89.73 Premark stockholders will receive a fraction
of a share of Illinois Tool Works common stock having a market value less than
or greater than $55 per share of Premark common stock, respectively. Under the
merger agreement, the maximum fraction of a share of Illinois Tool Works common
stock into which each share of Premark may be converted is 0.9181, which would
apply if the average closing price of Illinois Tool Works common stock is less
than or equal to $54.62; the minimum fraction is 0.5776, which would apply if
the average closing price of Illinois Tool Works common stock is greater than or
equal to $101.44.

     Please see page 30 for detailed information concerning the formula that
will be used to determine the fraction of a share of Illinois Tool Works common
stock Premark stockholders will receive for each of their shares.

     The following table illustrates how the formula in the merger agreement
works. The table shows some hypothetical examples of the average closing price
for shares of Illinois Tool Works common stock, the corresponding exchange ratio
computed using the formula in the merger agreement and the implied market value
paid per share of Premark common stock. We determined the implied market value
paid per share of Premark common stock by multiplying each hypothetical average
closing price for shares of Illinois Tool Works common stock by the
corresponding ex-

change ratio computed using the formula in the merger agreement.

    110.00        0.5776            63.54
</TABLE>

     As noted, the pricing formula in the merger agreement values Illinois Tool
Works shares as an average of the closing prices over a 20-day period; the
market value of the shares received by Premark stockholders in the merger on the
date they are received may be higher or lower than the average price.

MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

     Because the merger is expected to be treated as a "reorganization" for U.S.
federal income tax purposes, Premark stockholders are not expected to recognize
gain or loss for U.S. federal income tax purposes on the receipt of shares of
Illinois Tool Works common stock in the merger. However, Premark stockholders
will recognize gain or loss for U.S. federal income tax purposes with respect to
any cash received instead of fractional shares. See "The Merger Agreement and
the Merger -- Material Federal Income Tax Considerations."

     Tax matters are very complicated. The tax consequences of the merger to
Premark stockholders will depend on the facts of their own situations. Premark
stockholders should consult their tax advisors for a full understanding of the
U.S. federal, state and local and foreign tax consequences of the merger.

MARKET PRICES OF ILLINOIS TOOL WORKS COMMON STOCK AND PREMARK COMMON STOCK ON
IMPORTANT DATES

     The following table provides the closing per share prices of Illinois Tool
Works common stock and Premark common stock, as reported on the New York Stock
Exchange Composite Tape, on:

- - September 9, 1999 -- the last trading day before we announced the merger; and

  statement/prospectus.

PREMARK'S REASONS FOR THE MERGER

     Premark's board of directors, in reaching its decision to approve and
declare advisable the merger agreement, consulted with its legal counsel and
financial advisor as well as with Premark's management and considered many
factors, including the following material factors (the order does not reflect
the relative significance):

- - Stockholder Value: the fact that the expected per share consideration to be
  received by Premark stockholders represents a premium of approximately 60%
  over the closing price per share of Premark common stock on September 9, 1999,
  the last closing price prior to the announcement of the merger agreement;

- - Attractive Strategy: the attractiveness of the merger as compared to other
  alternatives available to Premark;

- - Experienced Management; Acquisition Success: the track record of Illinois Tool
  Works' management team generally in successfully operating diverse
  manufacturing businesses and specifically in making frequent acquisitions,
  applying its management techniques to acquired

                                        2
<PAGE>   9

businesses and improving the operating performance of such businesses;

- - Fairness Opinion: the presentation by and fairness opinion of Goldman, Sachs &
  Co. to the effect that as of September 9, 1999, the exchange ratio under the
  merger agreement was fair, from a financial point of view, to Premark
  stockholders. Goldman Sachs' fairness opinion is included as Annex B to this
  proxy statement/ prospectus and we urge you to read it in its entirety;

- - Continuing Stake in the Combined Company: the opportunity for Premark
  stockholders to continue as stockholders of the combined company, which has
  greater financial strength, global diversification and scale than Premark
  currently has;

- - Tax and Accounting Treatment: the expectation that the merger will qualify as
  a "reorganization" under Section 368(a) of the Internal Revenue Code and as a
  "pooling-of-interests" for financial accounting purposes; and

- - Terms of the Merger Agreement: the terms and conditions of the merger
  agreement, which provide Premark with a reasonable expectation that the merger
  will be completed.

     Premark's board of directors also considered a number of potentially
negative factors in its deliberations concerning the merger, including the
following material drawbacks and risks (the order does not reflect the relative
significance):

- - the risk that the benefits in the operating performance of Premark's
  businesses which are sought to be achieved in connection with the merger will
  not be achieved;

- - the risk that, should there be a large decrease in the market value of
  Illinois Tool Works common stock, the value of the consideration to be
  received by Premark stockholders in the merger could decline;

- - the risk that the merger will not be completed;

- - the risk that the termination fee provisions of the merger agreement and the
  stock option agreement may have the effect of discouraging a superior proposal
  by a third party for a business combination transaction with Premark.

ILLINOIS TOOL WORKS' REASONS FOR THE MERGER

     Illinois Tool Works' board of directors, in reaching its decision to
approve the merger agreement, consulted with its legal counsel as well as
Illinois Tool Works' management and considered many factors, including the
following material factors (the order does not reflect the relative
significance):

- - Growth Through Diversifying Acquisitions: Growth through diversifying
  acquisitions, both large and small, has been a key element of Illinois Tool
  Works' business plan for many years. The merger with Premark would add to
  Illinois Tool Works' already well-diversified portfolio of products.

- - Complementary Businesses: Premark is similar to and complementary with
  Illinois Tool Works' other businesses. Some of the factors that make Premark a
  "good strategic fit" include:

  -- Premark is an innovative designer and established manufacturer of products
     and systems that are targeted to commercial customers, the type of
     customers for many of Illinois Tool Works' other products;

  -- Premark has a long-standing reputation for products with well-known brand
     names, strong market positions and well-defined distribution channels;

  -- Premark products have a high degree of value-added engineering, like many
     of Illinois Tool Works' existing products; and

  -- Premark operates in a decentralized manner, and its businesses are
     entrepreneurial.

- - Improvement of Operating Margins: Illinois Tool Works believes that it can
  increase Premark's operating margins over the long term by introducing
  Illinois Tool Works' proven engineering and manufacturing expertise at
  Premark.

EXCHANGE OF STOCK CERTIFICATES

     If you have a Premark stock certificate, then promptly after the merger
takes place, Harris Trust and Savings Bank, the exchange agent for this
transaction, will send you a letter of transmittal for you to use in exchanging
your Premark common stock certificates for certificates representing shares of
Illinois Tool Works common

                                        3
<PAGE>   10

stock. You should not send in your Premark common stock certificates until you
receive the letter of transmittal. If you own Premark common stock through a
broker, Premark's employee benefit plans or other arrangement where you do not
hold a Premark certificate, then your stock certificates will be exchanged for
certificates representing Illinois Tool Works common stock without any action by
you.

NO APPRAISAL RIGHTS

     Under Delaware corporate law, neither Illinois Tool Works stockholders nor
Premark stockholders are entitled to dissenters' or appraisal rights in
connection with the merger.

COMPARATIVE RIGHTS OF ILLINOIS TOOL WORKS STOCKHOLDERS AND PREMARK STOCKHOLDERS

     Some of the rights of a stockholder of Illinois Tool Works are different
from the rights of a stockholder of Premark. One of the most important
differences is that Premark has a stockholder rights agreement that may
discourage unwelcome or hostile takeover attempts. Illinois Tool Works has no
such plan. Another difference is that Premark's board of directors is divided
into three classes, with only one class elected each year. In contrast, Illinois
Tool Works' entire board of directors stands for election every year.

COMPARATIVE PER SHARE INFORMATION

     The following table summarizes certain (1) historical financial information
and (2) unaudited pro forma and equivalent pro forma financial information on a
per share basis.

     The unaudited pro forma financial information assumes that the merger was
completed at the beginning of each of the periods presented for the statement of
income information and at the end of the period for the balance sheet
information and gives effect to the merger as a pooling-of-interests for
accounting purposes. The basic unaudited pro forma per share information for
Illinois Tool Works is based on the number of outstanding shares of Illinois
Tool Works common stock adjusted to include the number of shares of Illinois
Tool Works common stock that would be issued in the merger in exchange for the
outstanding Premark common stock at an assumed exchange ratio of 0.7049, which
was arrived at by dividing $55 by the average market value of Illinois Tool
Works common stock of $78.03 for the 20-day period ending September 9, 1999,
based on the number of shares of Premark common stock outstanding for the
periods reported. The diluted unaudited pro forma per share information for
Illinois Tool Works is based on the number of outstanding shares of Illinois
Tool Works common stock adjusted to include (1) the dilutive effect of
outstanding Illinois Tool Works employee stock options, (2) the number of shares
of Illinois Tool Works common stock that would be issued in the merger at the
assumed exchange ratio and (3) the dilutive effect of Premark employee stock
options.

     The unaudited equivalent pro forma per share information for Premark is
based on the unaudited pro forma amounts per share for Illinois Tool Works
multiplied by an assumed exchange ratio of 0.7049, which was arrived at by
dividing $55 by the average market value of Illinois Tool Works common stock of
$78.03 for the 20-day period ending September 9, 1999.

     The information set forth below is qualified in its entirety by reference
to, and should be read in conjunction with, the historical consolidated
financial information of Illinois Tool Works and Premark incorporated by
reference in this proxy statement/prospectus and the unaudited pro forma
combined financial statements included in this proxy statement/prospectus.

(1) Pro forma cash dividends per share have been computed by dividing the
    aggregate historical dividends of Illinois Tool Works and Premark by the
    combined weighted average number of shares of Illinois Tool Works common
    stock and Premark common stock for all periods presented assuming Premark
    stockholders receive 0.7049 of an Illinois Tool Works common share for each
    share of Premark common stock held. These amounts are not necessarily
    indicative of the future dividends to be paid by Illinois Tool Works.

(2) Premark's quarterly dividend was reduced in connection with its spin-off of
    Tupperware Corporation on May 31, 1996.

THE MEETINGS

     Premark

     The meeting of Premark stockholders will take place on November 23, 1999,
at Premark's headquarters at 1717 Deerfield Road, Deerfield, Illinois 60015, at
9:30 a.m. Central time. At the Premark meeting, Premark stockholders will be
asked to adopt the merger agreement.

     Illinois Tool Works

     The meeting of Illinois Tool Works stockholders will take place on November
23, 1999 at Harris Trust and Savings Bank, 111 West Monroe Street, Auditorium --
8th Floor West, Chicago,

                                        5
<PAGE>   12

Illinois 60603, at 11:00 a.m. Central time. At the
Illinois Tool Works meeting, Illinois Tool Works stockholders will be asked to
consider the issuance of Illinois Tool Works common stock in the merger.

VOTE REQUIRED

     Premark

     Each Premark stockholder on the record date is entitled to one vote on each
matter submitted to a vote at the meeting for each share of Premark common stock
then held. A majority of the shares of Premark common stock outstanding on the
record date constitutes a quorum at the meeting. If a quorum is present at the
meeting, the affirmative vote of at least a majority of the shares of Premark
common stock outstanding and entitled to vote is required to adopt the merger
agreement. Delaware corporate law requires that the Premark stockholders adopt
the merger agreement before we can complete the merger.

  Illinois Tool Works

     Each Illinois Tool Works stockholder on the record date is entitled to one
vote on each matter submitted to a vote at the meeting for each share of
Illinois Tool Works common stock then held. A majority of shares of Illinois
Tool Works common stock outstanding on the record date constitutes a quorum at
the meeting. If a quorum is present at the meeting, the affirmative vote of at
least a majority of the shares of common stock present and voting is required to
approve the issuance of Illinois Tool Works common stock in the merger.

     If the number of Illinois Tool Works shares to be issued in the merger is
less than 20% of the number of Illinois Tool Works shares outstanding at the
time of the merger, then the New York Stock Exchange listing requirements will
not require any vote by the stockholders of Illinois Tool Works. Because the
exact number of shares of Illinois Tool Works common stock to be issued in the
merger will not be known until the second business day prior to the merger, we
do not yet know whether we will be required to obtain the approval for the
issuance. Illinois Tool Works reserves the right to cancel the Illinois Tool
Works meeting at any time if it determines that no vote of the Illinois Tool
Works stockholders is required under the New York Stock Exchange listing
requirements.

THE MERGER AGREEMENT AND THE MERGER

     The merger agreement is attached as Annex A to this proxy
statement/prospectus. You should read the merger agreement because it, and not
this proxy statement/prospectus, is the legal document that governs the merger.

  Recommendation to Illinois Tool Works Stockholders

     Illinois Tool Works' board of directors has determined that the merger
agreement and the merger are in the best interests of Illinois Tool Works and
its stockholders. Accordingly, Illinois Tool Works' board of directors, by a
unanimous vote of all directors present, has approved the merger agreement, and
recommends that Illinois Tool Works stockholders vote to approve the issuance of
Illinois Tool Works common stock in connection with the merger. See "The Merger
Agreement and the Merger -- Background of the Merger" and "The Merger Agreement
and the Merger -- Recommendation of Illinois Tool Works' Board of Directors and
Reasons for the Merger."

  Recommendation to Premark Stockholders

     Premark's board of directors has determined that the merger agreement and
the merger are fair to and in the best interests of Premark and its
stockholders. Accordingly, Premark's board of directors, by a unanimous vote of
all directors present, has approved and declared advisable the merger agreement,
and recommends that Premark stockholders vote to adopt the merger agreement. See
"The Merger Agreement and the Merger -- Background of the Merger" and "The
Merger Agreement and the Merger -- Recommendation of Premark's Board of
Directors and Reasons for the Merger."

  Interests of Premark Directors and Officers in the Merger that are Different
from Premark Stockholders' Interests

     Some of the members of Premark's board of directors and some of Premark's
officers have interests in the merger that are different from Premark
stockholders' interests:

- - All outstanding options granted by Premark to purchase Premark common stock,
  including those held by officers and directors of Premark, will vest upon
  adoption of the merger by
                                        6
<PAGE>   13

Premark stockholders and, if not exercised before the merger, will be converted
into vested options to purchase shares of Illinois Tool Works common stock.

- - Restrictions on restricted stock awards granted to employees of Premark will
  lapse upon adoption of the merger agreement by Premark stockholders, and in
  the merger those shares will be converted into unrestricted shares of Illinois
  Tool Works common stock.

- - Premark's executive officers are each covered by individual employment
  agreements with Premark and by Premark benefit plans containing change of
  control provisions that become operative upon approval of the merger by
  Premark stockholders. If, after the merger, such executive's employment is
  terminated (1) without "cause" or by the affected executive for "good reason"
  or (2) for any reason during a 30-day period commencing on the first
  anniversary of the merger, the executive is entitled to certain severance
  benefits.

- - W. James Farrell, chairman and chief executive officer of Illinois Tool Works,
  is a director of Premark. Mr. Farrell did not take part in, and was not
  present during, any of the deliberations of Premark's board of directors
  concerning the merger or the merger agreement.

     It is expected that James M. Ringler, Premark's chairman, chief executive
officer and president, will assume a senior management role with Illinois Tool
Works after the merger.

     These interests are more fully described in "The Merger Agreement and the
Merger -- Interests of Premark Directors and Officers in the Merger that are
Different from Premark Stockholders' Interests."

     Premark's board of directors was aware of these interests and considered
them, among other matters, when approving the merger agreement.

     Illinois Tool Works intends to offer agreements to Mr. Ringler, William
Reeb, president of Wilsonart, a subsidiary of Premark, and possibly other
Premark executives who have not yet been designated in order to induce these
executives to stay with the combined company. The terms of these agreements have
not yet been determined. Illinois Tool Works may also make payments to some
Premark executives in exchange for a covenant not to compete.

     Premark's directors and officers beneficially owned, as of September 30,
1999, approximately 4.41% of Premark common stock. As of September 30, 1999,
Illinois Tool Works' directors and officers beneficially owned 2,196 shares of
Premark common stock.

  Opinion of Premark's Financial Advisor

     Premark's financial advisor, Goldman Sachs, delivered its opinion to
Premark's board of directors as to the fairness, from a financial point of view,
of the exchange ratio provided for in the merger. The full text of Goldman
Sachs' written opinion dated as of September 9, 1999 is attached to this proxy
statement/prospectus as Annex B. We encourage Premark stockholders to read this
opinion carefully in its entirety for a description of the procedures followed,
assumptions made, matters considered and limitations on the review undertaken.
GOLDMAN SACHS' OPINION IS DIRECTED TO PREMARK'S BOARD OF DIRECTORS AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO ANY MATTER RELATING TO THE
MERGER.

  What We Need to Do to Complete the Merger

     We will complete the merger only if the conditions set forth in the merger
agreement are satisfied or, if permissible, waived. These conditions include:

- - adoption of the merger agreement by Premark stockholders and, if required,
  approval of Illinois Tool Works' share issuance by Illinois Tool Works
  stockholders;

- - receipt of necessary antitrust approvals;

- - The absence of legal prohibitions to the merger, and of pending proceedings by
  specified governments seeking such prohibitions;

- - the continued effectiveness of Illinois Tool Works' registration statement
  relating to the merger filed with the Securities and Exchange Commission;

- - the approval for listing on the New York Stock Exchange of the Illinois Tool
  Works common stock to be issued in the merger;

- - Illinois Tool Works and Premark each having received a letter from its
  independent public

                                        7
<PAGE>   14

  accountants relating to qualification for "pooling-of-interests" accounting
  treatment;

- - the continued accuracy of the representations and warranties of each party;

- - the performance by each party of its obligations under the merger agreement;
  and

- - each party having received a legal opinion from its counsel to the effect that
  the merger will be treated as a reorganization under the Internal Revenue Code
  and that Illinois Tool Works, Premark and Merger Sub will each be a party to
  that reorganization.

     At any time before the merger, to the extent legally allowed, either
Illinois Tool Works or Premark may waive compliance with any of the conditions
contained in the merger agreement without the approval of their respective
stockholders. As of the date of this proxy statement/ prospectus, neither
Illinois Tool Works nor Premark expects that any condition will be waived.

Termination of the Merger Agreement

     Illinois Tool Works and Premark can agree to terminate the merger agreement
at any time without completing the merger.

     Also, either Illinois Tool Works or Premark can, without the consent of the
other, terminate the merger agreement if:

- - the merger is not completed by April 9, 2000, or, if extended by either party
  under limited circumstances to obtain governmental approvals of the merger,
  July 8, 2000, unless the party that wants to terminate the merger agreement
  has violated the agreement;

- - the Premark meeting is held and Premark stockholders do not adopt the merger
  agreement;

- - the Illinois Tool Works meeting is held and Illinois Tool Works stockholders
  do not approve the issuance of the Illinois Tool Works shares in the merger;

- - any order permanently restraining, enjoining or otherwise prohibiting
  completion of the merger becomes final and non-appealable; or

- - the other party materially breaches the merger agreement resulting in a
  failure of a condition to close the merger and the breaching party cannot or
  does not correct the breach before April 9, 2000, or, if extended under
  certain limited circumstances, July 8, 2000.

     In addition, Premark can terminate the merger agreement before the merger
if Premark receives an unsolicited proposal for a business combination
transaction with a third party that Premark's board of directors concludes is
superior to the merger with Illinois Tool Works, Premark gives Illinois Tool
Works at least four business days notice of its intention to enter into an
agreement for such superior proposal and, during that four-day period, Premark
considers any adjustment in the terms of the merger agreement that Illinois Tool
Works may propose.

     Illinois Tool Works can terminate the merger agreement if Premark's board
of directors withdraws, materially modifies in a manner adverse to Illinois Tool
Works or changes in a manner adverse to Illinois Tool Works its approval or
recommendation of the merger or the merger agreement.

  Termination Fee

     Premark must pay Illinois Tool Works a fee of $75 million in cash if the
merger agreement is terminated under a number of circumstances described
elsewhere in this proxy statement/ prospectus. See "The Merger Agreement and the
Merger -- Termination of the Merger Agreement." The termination fee is in
addition to any profit Illinois Tool Works may receive under the stock option
agreement described below.

  Non-Solicitation of Competing Proposals

     The merger agreement generally restricts Premark's ability to initiate,
solicit, knowingly encourage or intentionally facilitate any competing merger or
acquisition inquiries, proposals or offers; however, Premark may respond to
unsolicited offers as provided in the merger agreement.

THE STOCK OPTION AGREEMENT

     Premark has granted Illinois Tool Works an option to purchase up to
12,203,694 shares of Premark common stock, but not more than 19.9% of the number
of outstanding shares of Premark common stock, at a per share price in cash of
$34.06. Illinois Tool Works can exercise this option if it becomes entitled to
receive the
                                        8
<PAGE>   15

termination fee under the merger agreement. The
stock option agreement limits to $30 million the total profit Illinois Tool
Works may receive from the option. The profit Illinois Tool Works may receive
under the stock option agreement is in addition to the termination fee Illinois
Tool Works may receive under the merger agreement.

SELECTED UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

     The following summarizes the pro forma effect of the merger on Illinois
Tool Works by combining (1) the unaudited statements of income information for
the six months ended June 30, 1999 and the statements of income information for
the years ended December 31, 1996, 1997 and 1998 and (2) the unaudited
statements of financial position information as of June 30, 1999 and the
statements of financial position information as of December 31, 1996, 1997 and
1998 of Illinois Tool Works with those of Premark for the corresponding periods.

     The following information has been derived from the Unaudited Pro Forma
Combined Financial Statements included elsewhere in this proxy
statement/prospectus. The notes to the Unaudited Pro Forma Combined Financial
Statements set forth the estimates and assumptions upon which those financial
statements are based, including the fact that we used an estimated exchange
ratio of 0.7049 (see note (f)) and have not yet made adjustments to conform
Premark's depreciation method to that of Illinois Tool Works (see note (m)). The
amounts of the pro forma adjustments to conform depreciation methods are not
currently estimable, and may result in lower income from continuing operations
for each period presented. The pro forma statements are preliminary and have
been made solely for informational purposes, and therefore are not necessarily
indicative of the results of operations or financial position that might have
been achieved for the dates or periods indicated, nor are they necessarily
indicative of the results of operations or financial position that may occur in
the future.

     Management of Illinois Tool Works and Premark expect that the merger will
qualify as a "pooling-of-interests" business combination for accounting
purposes. Under that method of accounting, the recorded historical cost basis of
the assets and liabilities of Illinois Tool Works and Premark will be carried
forward to the combined company. Results of operations of the combined company
will include income of Illinois Tool Works and Premark for the entire fiscal
period in which the combination occurs, and the historical results of operations
of the separate companies for fiscal years before the merger will be combined
and reported as the results of operations of the combined company.

                                  RISK FACTORS

     In addition to the other information included in this proxy
statement/prospectus, you should carefully consider the following risk factors.
These matters should be considered in addition to the other information included
or incorporated by reference in this proxy statement/prospectus.

PREMARK STOCKHOLDERS MAY RECEIVE SHARES OF ILLINOIS TOOL WORKS COMMON STOCK
HAVING A VALUE OF LESS THAN $55 PER PREMARK SHARE.

     Premark stockholders will receive Illinois Tool Works common stock valued
under the merger agreement at $55 for each share of Premark common stock so long
as the average closing price of Illinois Tool Works common stock is greater than
or equal to $66.33 and less than or equal to $89.73 during the 20-day pricing
period under the merger agreement. However, if the average closing price of
Illinois Tool Works common stock is less than $66.33, Premark stockholders will
receive Illinois Tool Works common stock valued under the merger agreement at
less than $55 for each share of Premark common stock. As noted, the pricing
formula values Illinois Tool Works shares as an average of its closing prices
over a 20-day trading period; the market value of the shares received by Premark
stockholders in the merger on the date they are received may be higher or lower
than the average price.

FAILURE TO QUALIFY FOR "POOLING-OF-INTERESTS" ACCOUNTING TREATMENT WOULD
NEGATIVELY IMPACT REPORTED OPERATING RESULTS.

     If, after completion of the merger, the merger fails to qualify for
"pooling-of-interests" accounting treatment, the purchase method of accounting
will apply. Under that method, the estimated fair value of the shares of
Illinois Tool Works common stock issued in the merger would be recorded as the
cost of acquiring Premark. That cost would be allocated to the individual
Premark assets acquired and liabilities according to their respective fair
values with the excess being recorded as goodwill. This goodwill would then be
amortized over its estimated useful life up to a maximum of 40 years.

     Purchase accounting treatment would have a material adverse effect on the
reported operating results of Illinois Tool Works as compared to
"pooling-of-interests" accounting treatment. The purchase accounting method
requires charges to Illinois Tool Works' earnings for amortization of goodwill
and, in all likelihood, increased depreciation and amortization charges relating
to the excess of fair value of individual assets over their carrying values.

THE INTEGRATION OF PREMARK INTO ILLINOIS TOOL WORKS MAY BE DIFFICULT AND
EXPENSIVE TO ACHIEVE AND MAY NOT RESULT IN THE BENEFITS CURRENTLY ANTICIPATED BY
ILLINOIS TOOL WORKS.

     The merger will present challenges to management, including the integration
of the operations, technologies and personnel of Illinois Tool Works and
Premark, and special risks, including possible unanticipated liabilities,
unanticipated costs, diversion of management attention and loss of personnel.

     Illinois Tool Works may not be able to integrate successfully or manage
profitably Premark's businesses. Following the merger, Premark's businesses may
not achieve sales levels, profitability or cost savings that justify the
investment made by Illinois Tool Works. The acquisition, while expected to be
accretive to earnings in future periods, may fail to be accretive or earnings
accretion may occur later than planned.

EXPENSES RESULTING FROM THE MERGER WILL BE SUBSTANTIAL AND MAY AFFECT ILLINOIS
TOOL WORKS' RESULTS OF OPERATIONS.

     We estimate that we will incur combined aggregate direct transaction costs
of approximately $20 million associated with the merger, consisting of
transaction fees for investment bankers, attorneys, accountants and other
related costs. These one-time transaction costs will be charged to expenses upon
completion of the merger. Following the merger, the combined company is expected
to incur additional one-time charges related to contractual termination payments
for Premark management of approximately

                                       12
<PAGE>   19

$35.3 million, net of related tax benefits. We cannot assure you that the
combined company will not incur any other additional charges in connection with
the merger.

THE PRICE OF ILLINOIS TOOL WORKS COMMON STOCK MAY BE AFFECTED BY FACTORS
DIFFERENT FROM THOSE AFFECTING THE PRICE OF PREMARK COMMON STOCK.

     Upon completion of the merger, holders of Premark common stock will become
holders of Illinois Tool Works common stock. Illinois Tool Works' businesses
differ from those of Premark. Illinois Tool Works' results of operations, as
well as the price of Illinois Tool Works common stock, may be affected by
factors different from those which affect Premark's results of operations and
the price of Premark common stock. See "Market Prices and Dividend Information."
For a discussion of Illinois Tool Works' and Premark's businesses and certain
factors to consider in connection with their businesses, see Illinois Tool
Works' Annual Report on Form 10-K for the fiscal year ended December 31, 1998,
and Premark's Annual Report on Form 10-K for the fiscal year ended December 26,

statement/prospectus.

PURPOSE OF THE PREMARK MEETING

     At the Premark meeting, Premark stockholders will be asked to consider and
vote upon:

     - a proposal to adopt the merger agreement; and

     - such other business as may properly be brought before the Premark
       meeting.

     Premark's board of directors is not aware, as of the date of this proxy
statement/prospectus, of any other matters that may properly come before the
Premark meeting. If any such other matters properly come before the Premark
meeting, or at a subsequent meeting following any adjournment or postponement of
the Premark meeting, the persons named in Premark's proxy intend to vote proxies
in accordance with their discretion on any such matters unless other
instructions are given.

     Premark's board of directors carefully reviewed and considered the terms
and conditions of the merger and concluded that the merger is in the best
interests of Premark and its stockholders. ACCORDINGLY, PREMARK'S BOARD OF
DIRECTORS, BY A UNANIMOUS VOTE OF ALL DIRECTORS OTHER THAN MR. FARRELL, WHO DID
NOT PARTICIPATE IN ANY DELIBERATIONS WITH RESPECT TO THE MERGER, APPROVED AND
DECLARED THE ADVISABILITY OF THE MERGER AGREEMENT AND RECOMMENDS THAT PREMARK
STOCKHOLDERS VOTE TO ADOPT THE MERGER AGREEMENT.

PURPOSE OF THE ILLINOIS TOOL WORKS MEETING

     At the Illinois Tool Works meeting, Illinois Tool Works stockholders will
be asked to consider and vote upon:

     - a proposal to issue Illinois Tool Works common stock in the merger; and

     - such other business as may properly be brought before the Illinois Tool
       Works meeting.

     Based upon the number of shares of Premark common stock currently
outstanding, plus employee stock options to acquire Premark common stock, and
the formula in the merger agreement which determines the fraction of a share of
Illinois Tool Works common stock to be issued in exchange for each

                                       15
<PAGE>   22

share of Premark common stock, Illinois Tool Works expects to issue between
approximately 39.5 million and 62.8 million shares of its common stock in the
merger.

     Illinois Tool Works' board of directors is not aware, as of the date of
this proxy statement/prospectus, of any other matters that may properly come
before the Illinois Tool Works meeting. If any such other matters properly come
before the Illinois Tool Works meeting, or at a subsequent meeting following any
adjournment or postponement of the Illinois Tool Works meeting, the persons
named in Illinois Tool Works' proxy intend to vote proxies in accordance with
their discretion on any such matters unless other instructions are given.

     Illinois Tool Works' board of directors carefully reviewed and considered
the terms and conditions of the merger and concluded that the merger is in the
best interests of Illinois Tool Works and its stockholders. ACCORDINGLY, THE
ILLINOIS TOOL WORKS BOARD OF DIRECTORS, BY A UNANIMOUS VOTE OF ALL DIRECTORS
PRESENT AND VOTING AT A MEETING AT WHICH A QUORUM OF DIRECTORS WAS PRESENT,
APPROVED THE MERGER AGREEMENT AND RECOMMENDS THAT ILLINOIS TOOL WORKS
STOCKHOLDERS VOTE TO APPROVE THE ISSUANCE OF ILLINOIS TOOL WORKS COMMON STOCK IN
THE MERGER.

     The Illinois Tool Works meeting is being held solely to comply with the
listing requirements of the New York Stock Exchange. If the number of Illinois
Tool Works shares to be issued in the merger is less than 20% of the number of
Illinois Tool Works shares outstanding at the time of the merger, then the New
York Stock Exchange listing requirements will not require any vote by the
stockholders of Illinois Tool Works. Illinois Tool Works reserves the right to
cancel the Illinois Tool Works meeting at any time if it determines that no vote
of the Illinois Tool Works stockholders is required under the New York Stock
Exchange listing requirements.

VOTING RIGHTS OF STOCKHOLDERS; VOTES REQUIRED FOR APPROVAL

  Voting Rights of Premark Stockholders

     The record date to determine who is entitled to vote at the Premark meeting
is October 11, 1999. Only holders of record of Premark common stock at the close
of business on the record date are entitled to notice of, or to vote at, the
Premark meeting. If your Premark common stock is registered in the name of a
brokerage firm or trustee and you plan to attend the Premark meeting, you must
obtain from the firm or trustee a letter, account statement or other evidence of
your beneficial ownership of those shares of Premark common stock in order to be
admitted to the Premark meeting. You must bring that documentation to the
meeting to attend. As of the record date, 61,427,603 shares of Premark common
stock, and no shares of Premark capital stock other than common stock, were
outstanding and entitled to vote.

     The Premark meeting may be adjourned or postponed to another date or place
for proper purposes, including for the purpose of soliciting additional proxies.
Unless revoked, proxies will remain valid following such adjournment or
postponement.

     Each stockholder of record on the record date is entitled to one vote on
each matter submitted to a vote at the Premark meeting for each share of Premark
common stock held. A majority of the shares of Premark common stock outstanding
on the record date represented in person or by proxy will constitute a quorum
for consideration of such matters at the Premark meeting. Abstentions and broker
non-votes will be counted as present or represented for the purpose of
determining a quorum. If a quorum is present at the Premark meeting, under
Delaware corporate law the affirmative vote of a majority of the shares of
Premark common stock outstanding and entitled to vote is required to adopt the
merger agreement. Abstentions and broker non-votes will have the effect of votes
against the merger.

     PREMARK'S BOARD OF DIRECTORS URGES PREMARK STOCKHOLDERS TO COMPLETE, SIGN,
DATE AND RETURN THE ENCLOSED PROXY CARD IN THE ACCOMPANYING SELF-ADDRESSED
STAMPED ENVELOPE OR VOTE BY TELEPHONE, FAX OR THE INTERNET AS SOON AS POSSIBLE.

                                       16
<PAGE>   23

     If you own stock or maintain multiple accounts under different names, for
example, with and without a middle initial, you may receive more than one set of
proxy statement/prospectus materials. To ensure that all of your shares of
Premark common stock are voted, you must sign and return by mail every proxy
card you receive.

  Voting Rights of Illinois Tool Works Stockholders

     The record date to determine who is entitled to vote at the Illinois Tool
Works meeting is October 11, 1999. Only holders of record of Illinois Tool Works
common stock at the close of business on the record date are entitled to notice
of, or to vote at, the Illinois Tool Works meeting. If your Illinois Tool Works
common stock is registered in the name of a brokerage firm or trustee and you
plan to attend the meeting, you must obtain from the firm or trustee a letter,
account statement or other evidence of your beneficial ownership of those shares
of Illinois Tool Works common stock in order to be admitted to the Illinois Tool
Works meeting. You must bring that documentation to the meeting to attend. As of
the record date, 250,674,938 shares of Illinois Tool Works common stock, and no
shares of Illinois Tool Works capital stock other than common stock, were
outstanding and entitled to vote.

     The Illinois Tool Works meeting may be adjourned or postponed to another
date or place for proper purposes, including for the purpose of soliciting
additional proxies. Unless revoked, proxies will remain valid following such
adjournment or postponement.

     Each stockholder of record on the record date is entitled to one vote on
each matter submitted to a vote at the Illinois Tool Works meeting for each
share of Illinois Tool Works common stock then held. A majority of the shares of
Illinois Tool Works common stock outstanding on the record date represented in
person, or by proxy, will constitute a quorum for consideration of such matters
at the Illinois Tool Works meeting. Abstentions and broker non-votes will be
counted as present or represented for the purpose of determining a quorum. If a
quorum is present at the Illinois Tool Works meeting, the affirmative vote of a
majority of the shares of Illinois Tool Works common stock present and voting is
required to approve the issuance of Illinois Tool Works common stock in
connection with the merger. Abstentions and broker non-votes will not be counted
in favor of the stock issuance proposal and will not be treated as votes cast on
such proposal. Because the stock issuance proposal requires the affirmative vote
of a majority of the votes cast by stockholders entitled to vote and voting at
the meeting, abstentions and broker non-votes will have no effect with respect
to the stock issuance proposal, provided that a quorum is present.

     ILLINOIS TOOL WORKS' BOARD OF DIRECTORS URGES ILLINOIS TOOL WORKS
STOCKHOLDERS TO COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD IN THE
ACCOMPANYING SELF-ADDRESSED STAMPED ENVELOPE OR VOTE BY TELEPHONE, FAX OR THE

example, with and without a middle initial, you may receive more than one set of
proxy statement/prospectus materials. To ensure that all of your shares of
Illinois Tool Works common stock are voted, you must sign and return by mail
every proxy card you receive.

GIVING AND REVOKING YOUR PROXY; SOLICITATION

     You may vote your shares either in person or by duly authorized proxy. By

your shares, in the case of Premark stockholders, FOR the adoption of the merger
agreement and any amendments to the merger agreement, and, in the case of
Illinois Tool Works stockholders, FOR the Illinois Tool Works proposal to issue
Illinois Tool Works common stock in connection with the merger. By granting a
proxy to vote FOR the proposal, Premark stockholders will be authorizing the
voting of their shares in favor of the adoption of the merger agreement and any
amendments to the merger agreement and to transact any other business that may
come before the Premark meeting or any adjournments or postponements of the
meeting. By granting a proxy to vote FOR the proposal, Illinois Tool Works
stockholders will be
                                       17
<PAGE>   24

authorizing the voting of their shares in favor of the approval of the issuance
of Illinois Tool Works shares pursuant to the merger agreement and any
amendments to the merger agreement and to transact any other business that may
come before the Illinois Tool Works meeting or any adjournments or postponements
of the meeting. If any other matters are properly presented for consideration at
the Illinois Tool Works or Premark meeting, or any adjournments or postponements
of the meeting, the proxyholders will have the discretion to vote in accordance
with their best judgment.

     You may grant a proxy by:

     - calling the toll-free number listed on your proxy card and following the

     - faxing your proxy card to the telephone number listed on your proxy card;
       or

     - going to the Internet website listed on your proxy card and following the
       instructions provided.

     If your shares are not registered in your own name, the bank, broker or
other institution holding your shares of Premark or Illinois Tool Works common
stock may not offer telephone, fax or Internet proxy voting. If your proxy card

and return your proxy card by mail. You may also cast your vote in person at the
meeting.

in person. You may revoke a previously submitted proxy at any time before it is
voted by delivering written notice of revocation to your company's corporate
secretary, by executing a subsequently dated proxy that is received prior to the
Premark meeting or the

                                       18
<PAGE>   25

Illinois Tool Works meeting or by voting in person at such meeting. Attendance
at the Premark meeting or the Illinois Tool Works meeting will not by itself
constitute revocation of a proxy. If you have instructed a broker to vote your
shares, you must follow directions received from the broker to change or revoke
your proxy.

  Solicitation

     In addition to soliciting proxies by mail, officers, directors and
employees of Premark or Illinois Tool Works, without receiving any additional
compensation, may solicit proxies by telephone, in person or by other means.
Arrangements will also be made with brokerage firms and other custodians,
nominees and fiduciaries to forward proxy solicitation materials to the
beneficial owners of Premark and Illinois Tool Works common stock held of record
by those persons, and both companies will reimburse the brokerage firms,
custodians, nominees and fiduciaries for reasonable out-of-pocket expenses
incurred by them in connection with the solicitation. Premark and Illinois Tool
Works have retained MacKenzie Partners, Inc. to assist in the solicitation of
proxies at an estimated cost of $20,000.

NO APPRAISAL RIGHTS

     Under Delaware corporate law, neither the holders of Premark common stock
nor the holders of Illinois Tool Works common stock are entitled to dissenters'
or appraisal rights in connection with the merger.

                      THE MERGER AGREEMENT AND THE MERGER

BACKGROUND OF THE MERGER

     In March 1999, W. James Farrell, Illinois Tool Works' chairman and chief
executive officer, and a director of Premark, approached James M. Ringler,
Premark's chairman, chief executive officer and president, about the possibility
of a combination between Premark and Illinois Tool Works. Messrs. Farrell and
Ringler engaged in occasional preliminary discussions about a possible
combination between March 1999 and July 1999. In the second half of July 1999,
Messrs. Farrell and Ringler first discussed possible terms of a stock-for-stock,
"pooling-of-interests" transaction along the lines of the merger which Premark
and Illinois Tool Works ultimately negotiated.

     At Premark's regularly scheduled board of directors meeting on August 4,
1999, Mr. Ringler, with Mr. Farrell having excused himself from the meeting,
described the initial outlines of the transaction envisioned by Mr. Farrell.
After that meeting, Messrs. Farrell and Ringler continued their discussions
about a possible transaction. On August 6, 1999, Illinois Tool Works' board of
directors met and discussed a possible transaction between Illinois Tool Works
and Premark along the lines envisioned by Mr. Farrell.

     On August 25, 1999, Premark and Illinois Tool Works entered into a
confidentiality agreement. On August 27, 1999, Premark's board of directors met
to consider the status of the discussions with Illinois Tool Works. Mr. Ringler
reviewed with Premark's board of directors his conversations with Mr. Farrell
and the strategic and financial rationale for a possible transaction. The board
also received a presentation from its financial advisor concerning Premark,
Illinois Tool Works and the financial aspects of a potential combination, as
well as a presentation from its legal advisors. Mr. Farrell, who had not been
present at the meeting, was invited into the meeting for the purpose of
describing Illinois Tool Works and its businesses and his view of Premark's fit
with Illinois Tool Works.

     Beginning on August 30, 1999, and continuing until the merger agreement and
stock option agreement were signed, representatives of each of Premark and
Illinois Tool Works conducted a due diligence investigation of the other
company, including the exchange of information regarding the businesses and
operations of their respective companies.

     Mr. Ringler and Mr. Farrell met several times between August 31, 1999 and
September 7, 1999 to negotiate aspects of the proposed business combination, in
particular the consideration that would be received by Premark stockholders in
the merger, including the pricing and tax treatment.

     Representatives of Illinois Tool Works and Premark negotiated the terms of
the definitive agreements between August 31, 1999 and September 9, 1999.

     On September 9, 1999, Premark's board of directors met to consider the
proposed transaction and agreements. Mr. Farrell did not attend Premark's board
meeting. At Premark's board meeting, Mr. Ringler, representatives of Goldman
Sachs and Premark's special counsel addressed the board about the business,
financial, and legal implications, respectively, of a merger between Illinois
Tool Works and Premark and the terms of the proposed agreements. During the
meeting, representatives of Goldman Sachs informed the board that in the opinion
of Goldman Sachs, as of September 9, 1999, the exchange ratio under the proposed
merger agreement was fair, from a financial point of view, to Premark
stockholders. After discussion, Premark's board of directors voted to approve
and declare advisable the agreements and resolved to recommend that Premark
stockholders vote for the adoption of the merger agreement at a stockholders
meeting to be held for that purpose.

     Illinois Tool Works' board of directors also met on September 9, 1999 to
consider the proposed transaction and agreements. At Illinois Tool Works' board
meeting, members of Illinois Tool Works' management discussed with the board
business, financial and legal aspects of the transaction and the agreements, and
legal counsel discussed with the board the legal aspects of the transaction and
the proposed agreements. After that discussion, Illinois Tool Works' board of
directors voted to approve and declare advisable the agreements and resolved to
recommend that Illinois Tool Works stockholders vote to approve the issuance of
the Illinois Tool Works shares to be issued in the merger should stockholder
approval of the issuance be required by New York Stock Exchange rules.

     Following Premark's board of directors meeting and Illinois Tool Works'
board of directors meeting, the parties executed the merger agreement and the
stock option agreement.

RECOMMENDATION OF PREMARK'S BOARD OF DIRECTORS AND REASONS FOR THE MERGER

     Premark's board of directors, in reaching its decision to approve the
merger agreement, consulted with its legal counsel and financial advisor as well
as with Premark's management and considered many factors, including the
following material factors (the order does not reflect the relative
significance):

     - Stockholder Value: the fact that the expected per share consideration to
       be received by Premark stockholders represents a premium of approximately
       60% over the closing price per share of Premark common stock on September
       9, 1999 ($34.25 per share), the last closing price prior to the
       announcement of the merger agreement (assuming the average closing price
       of Illinois Tool Works common stock under the merger agreement is between
       $66.33 and $89.73). The provisions of the merger agreement that specify
       the exchange ratio protect Premark stockholders from the effect of a
       decline in the price of Illinois Tool Works common stock within a certain
       range;

     - Attractive Strategy: the attractiveness of the merger as compared to
       other alternatives available to Premark, such as remaining an independent
       company or attempting to enhance Premark's business through the
       acquisition of, or merger with, other companies;

     - Experienced Management; Acquisition Success: the track record of the
       Illinois Tool Works management team generally in successfully operating
       diverse manufacturing businesses, and specifically in making frequent
       acquisitions, applying its management techniques to acquired businesses
       and improving the operating performance of such businesses;

     - Fairness Opinion: the presentation by and fairness opinion of Goldman
       Sachs to the effect that as of September 9, 1999, the exchange ratio
       under the merger agreement was fair, from a financial point of view, to
       Premark stockholders. See "-- Opinion of Premark's Financial Advisor."

<PAGE>   27

       Sachs' fairness opinion is included as Annex B to this proxy
       statement/prospectus and we urge Premark stockholders to read it in its
       entirety;

     - Continuing Stake in Combined Company: the opportunity for Premark
       stockholders to continue as stockholders of a combined company with
       greater financial strength, global diversification and scale than Premark
       currently has;

     - Tax and Accounting Treatment: the expectation that the merger will
       qualify as a "reorganization" under Section 368(a) of the Internal
       Revenue Code (see "-- Material Federal Income Tax Considerations") and as
       a "pooling-of-interests" for financial accounting purposes (see
       "-- Anticipated Accounting Treatment"); and

     - Terms of the Merger Agreement: the terms and conditions of the merger
       agreement which provide Premark with a reasonable expectation that the
       merger will be completed, including the conditions to closing and the
       representations and warranties of each of the parties to the merger
       agreement, particularly the relatively high standard of materiality by
       which each party's representations and warranties are generally
       qualified.

     Premark's board also considered a number of potentially negative factors in
its deliberations concerning the merger, including the following material
drawbacks and risks (the order does not reflect the relative significance):

     - the risk that the benefits in the operating performance of Premark's
       businesses that are sought to be achieved in connection with the merger
       will not be achieved;

     - the risk that, should there be a large decrease in the market value of
       Illinois Tool Works common stock, the value of the consideration to be
       received by Premark stockholders in the merger could decline; in this
       regard, the merger agreement does not provide either party a right of
       termination based on a decline, or an increase, in the market price of
       Illinois Tool Works common stock;

     - the risk that the merger will not be completed and the potential effects
       the failure to complete the merger might have on the business, employees
       and customers of Premark;

     - the risk that although the merger agreement gives Premark the right to
       terminate such agreement if a superior proposal for a business
       combination with Premark is made, the termination fee provisions of the
       merger agreement would have the effect of discouraging such a proposal.
       In addition, Premark's board of directors considered the risk that the
       stock option agreement would have the effect of precluding any
       alternative business combination with Premark from being accounted for as
       a "pooling-of-interests," which would be an impediment to alternative
       business combination proposals. Premark's board of directors accepted
       these provisions as a means to obtain other terms (principally the
       exchange ratio) that are favorable to Premark, and did not believe that
       such terms could be otherwise obtained in the negotiations with Illinois
       Tool Works; and

     - the matters described under "Risk Factors" in this proxy
       statement/prospectus.

     This summary is not meant to be an exhaustive description of the
information and factors considered by Premark's board of directors but is
believed to include all material factors that the board considered. In view of
the wide variety of factors considered by Premark's board of directors, it was
not possible to quantify or to give relative weights to the various factors,
particularly as each director may have assigned different weight to different
factors. Premark's board of directors considered all these factors as a whole,
and concluded that the merger overall was fair to, and in the best interests of,
Premark and its stockholders.

RECOMMENDATION OF ILLINOIS TOOL WORKS' BOARD OF DIRECTORS AND REASONS FOR THE
MERGER

     Illinois Tool Works' board of directors, in reaching its decision to
approve the merger agreement, consulted with its legal counsel as well as
Illinois Tool Works' management and considered many factors, including the
following material factors (the order does not reflect the relative
significance):

     - Growth Through Diversifying Acquisitions: Growth through diversifying
       acquisitions, both large and small, has been a key element of Illinois
       Tool Works' business plan for many years. Prior to the proposed
       transaction with Premark, Illinois Tool Works has implemented this
       strategy through several major diversifying acquisitions including (1)
       the acquisition of Signode in the field of industrial packaging, (2) the
       acquisition of Ransburg in the field of industrial spray finishing, and
       (3) the acquisition of Miller Electric in the field of welding equipment.
       As with these three acquisitions, the merger with Premark would add to
       Illinois Tool Works' already well-diversified portfolio of products.
       Product diversification helps make Illinois Tool Works' revenue and
       earnings growth more predictable, particularly during times of economic
       recession.

     - Complementary Businesses: Premark is similar to and complementary with
       Illinois Tool Works' other businesses. The factors that make Premark a
       "good strategic fit" include:

        -- Premark is an innovative designer and established manufacturer of
           products and systems that are targeted to commercial customers, the
           type of customers for many of Illinois Tool Works' other products;

          -- Premark has a long-standing reputation for developing products of
             the type Illinois Tool Works produces with well-known brand names,
             strong market positions and well-defined distribution channels;

          -- Premark products have a high degree of value-added engineering,
             like many of Illinois Tool Works' existing product lines; and

          -- Premark operates in a decentralized manner, and its businesses are
             entrepreneurial, which is similar to the way Illinois Tool Works is
             organized.

     - Improvement of Operating Margins: Illinois Tool Works believes that it
       can increase Premark's operating margins over the long term by
       introducing Illinois Tool Works' proven engineering and manufacturing
       expertise to Premark's business.

OPINION OF PREMARK'S FINANCIAL ADVISOR

     Premark retained Goldman Sachs pursuant to a letter agreement, dated August
2, 1999, to act as financial advisor in connection with a possible merger
transaction involving Illinois Tool Works. Goldman Sachs is a nationally
recognized investment banking firm and was selected by Premark based on the
firm's reputation and experience in investment banking in general and its
recognized expertise in the valuation of businesses, as well as its prior
investment banking relationship with Premark. On September 9, 1999, at the
meeting of Premark's board of directors, Goldman Sachs delivered to Premark's
board of directors its oral opinion (which was subsequently confirmed in a
written opinion dated as of September 9, 1999) that, as of such date and based
on and subject to the matters set forth therein, the exchange ratio was fair
from a financial point of view to the holders of Premark common stock.

     You should consider the following when reading the discussion of Goldman
Sachs' opinion in this document:

     - We urge you to read carefully the entire opinion of Goldman Sachs, which
       is set forth in Annex B of this proxy statement/prospectus and is
       incorporated herein by reference.

     - Goldman Sachs' advisory services and opinion were provided to Premark's
       board of directors for its information in its consideration of the merger
       and the opinion was directed only to the fairness of

                                       22
<PAGE>   29

the exchange ratio from a financial point of view to the holders of the
outstanding shares of Premark common stock.

     - Goldman Sachs' opinion does not constitute a recommendation to any holder
       of Premark common stock as to how to vote on the merger or any related
       matter.

     Although Goldman Sachs evaluated the fairness, from a financial point of
view, of the exchange ratio to the holders of Premark common stock, the exchange
ratio itself was determined by Premark and Illinois Tool Works through
arm's-length negotiations. Premark did not provide specific instructions to, or
place any limitations on, Goldman Sachs with respect to the procedures to be
followed or factors to be considered by Goldman Sachs in performing its analyses
or providing its opinion.

     In connection with its opinion, Goldman Sachs reviewed, among other things,
the following:

     - the merger agreement;

     - the Annual Reports to Stockholders and Annual Reports on Form 10-K of
       Premark and Illinois Tool Works for each of the previous five years;

     - certain interim reports to stockholders and Quarterly Reports on Form
       10-Q of Premark and Illinois Tool Works;

     - certain other communications from Premark and Illinois Tool Works to
       their respective stockholders; and

     - certain internal financial analyses and forecasts for Premark and
       Illinois Tool Works prepared by their respective managements.

     Goldman Sachs also held discussions with members of the senior management
of Premark and Illinois Tool Works regarding the past and current business
operations, financial condition and future prospects of each company. In
addition, Goldman Sachs reviewed the reported price and trading activity for
Premark common stock and Illinois Tool Works common stock, compared certain
financial and stock market information for Premark and Illinois Tool Works with
similar information for certain other companies the securities of which are
publicly traded, reviewed the financial terms of certain recent business
combinations in the food equipment industry specifically and in other industries
generally, and performed such other studies and analyses as it considered
appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed such accuracy and
completeness for purposes of rendering its opinion. In addition, because
Illinois Tool Works did not prepare internal forecasts beyond the current fiscal
year, Goldman Sachs' review of such information was limited to discussions with
senior managers of Illinois Tool Works regarding research analysts' estimates
for Illinois Tool Works.

     In connection with Goldman Sachs' role as financial advisor to Premark,
Goldman Sachs was not requested to solicit, and did not solicit, interest from
other parties with respect to an acquisition or other business combination with
Premark.

     Goldman Sachs did not make any independent evaluation or appraisal of the
assets and liabilities of Premark or Illinois Tool Works or any of their
respective subsidiaries and Goldman Sachs was not furnished with any such
evaluation or appraisal. Goldman Sachs assumed, with the consent of Premark's
board of directors, that the transaction contemplated by the merger agreement
will be accounted for as a "pooling-of-interests" under generally accepted
accounting principles.

     Goldman Sachs, as part of its investment banking business, is continually
engaged 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 estate, corporate and other purposes. Goldman Sachs is
familiar with Premark, having provided investment banking and financial advisory
services to Premark from time to time, including

                                       23
<PAGE>   30

having acted as lead managing underwriter of a public offering of $150,000,000
aggregate principal amount of 6.875% Notes due November 15, 2008 of Premark in
November 1998 and having acted as its financial adviser in connection with, and
having participated in certain of the negotiations leading to, the merger
agreement. Goldman Sachs provides a full range of financial advisory and
securities services and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of Premark and Illinois Tool Works for its own account or the
accounts of customers.

     The following is a summary of the material financial analyses used by
Goldman Sachs in reaching its opinion and does not purport to be a complete
description of the analyses performed by Goldman Sachs. The following
quantitative information, to the extent it is based on market data, is based on
market data as it existed at or about September 9, 1999 and is not necessarily
indicative of current market conditions. Readers should understand that the
order of analyses and the results derived from these analyses described below do
not represent relative importance or weight given to these analyses by Goldman
Sachs. The summary of the financial analyses includes information presented in
tabular format. IN ORDER TO UNDERSTAND FULLY THE FINANCIAL ANALYSES USED BY
GOLDMAN SACHS, THESE TABLES MUST BE READ TOGETHER WITH THE TEXT OF EACH SUMMARY.
THE TABLES ALONE DO NOT DESCRIBE COMPLETELY THE FINANCIAL ANALYSES.

     Historical Stock Performance; Estimated Transaction Premiums. Goldman Sachs
reviewed the weekly indexed historical prices for shares of Premark common stock
and Illinois Tool Works common stock during the period from September 6, 1996 to
September 3, 1999, as compared to industry indices. Goldman Sachs also reviewed
the recent and historical prices and trading volume for shares of Premark common
stock and Illinois Tool Works common stock. Goldman Sachs reviewed estimated
premiums for the merger based on a price per share of Premark common stock of
$55.00. Such price represented a premium of approximately 60.9% to the price of
Premark common stock on the close of business on September 8, 1999, a premium of
approximately 101.8% to the lowest closing trading price of Premark common stock
during the 52-week period ending on September 8, 1999 and a premium of
approximately 41.9% to the highest closing trading price of Premark common stock
during the 52 weeks ending on September 8, 1999.

     Analysis of Selected Publicly Traded Companies. Goldman Sachs reviewed
certain financial, market and operating information of Premark with
corresponding data for four groups of companies (collectively, the "Premark
Selected Companies"): a group of commercial food equipment companies, consisting
of Hussmann, Manitowoc, Maytag, Specialty Equipment and Whirlpool; a group of
building products companies, consisting of American Standard, Armstrong World
Industries, Congoleum, Dal-Tile, Masco, Stanley Works and TJ International; a
group of consumer products companies, consisting of Black & Decker, Nacco,
National Presto, Sunbeam and Windmere-Durable; and a group of fitness equipment
companies, consisting of Brunswick, Cybex International, Callaway Golf,
Cannondale, Delta Woodside, Huffy and K2. The following table sets forth the
values for Premark, and the ranges and medians for each group of Premark
Selected Companies, of:

     (1) the closing price, on September 8, 1999, as a percentage of the 52-week
high;

     (2) multiples of levered market capitalization (including preferred stock)
         ("Levered Market Capitalization") to each of the latest twelve months
         ("LTM") sales and the LTM earnings before interest expense, income
         taxes and depreciation and amortization ("EBITDA");

     (3) market price to earnings ("P/E") multiples for the calendar years 1999
         and 2000, based on earnings estimates reported by the Institutional
         Brokers Estimate System ("IBES") as of September 8, 1999;

     (4) the LTM EBITDA margin (excluding extraordinary items, restructuring
         costs, write-offs and other income not related to regular operations);

     (5) the projected five-year earnings per share compound annual growth as
         estimated by IBES (the "IBES Growth Rate");

     (6) the ratio of 2000 P/E to the IBES Growth Rate; and

     (7) the ratio of the 1999 P/E to the S&P 500 P/E multiple.

     Projected earnings per share and compound annual growth rate were based on
IBES estimates. LTM sales and EBITDA, and Levered Market Capitalization were
based on publicly available information.

     Analysis of Selected Transactions: Goldman Sachs reviewed the financial
terms, to the extent publicly available, of selected pending or completed
mergers and acquisitions transactions since December 1993 in the food equipment
industry (the "Food Equipment Industry Selected Transactions"). Goldman Sachs
based this analysis on publicly available information for each of the Food
Equipment Industry Selected Transactions. The transactions involved were:
Berisford/Scotsman; York International/Sabroe Refrigeration; Maytag/Jade Range;
Hussmann International/Koxka; TI Group/EIS Group; United Technologies/Tyler;
Sidel/Gebo Industries; Whirlpool/Brasmotor; Manitowoc/Servend International;
Maytag/Blodgett; Scotsman/Kysor; FMC/Frigoscandia Equipment; Manitowoc/Shannon
Group; Berisford/Welbilt; Welbilt/Lincoln Foodservice Products; and
Scotsman/Delfield/Whitlenge. Goldman Sachs calculated the multiple of levered
consideration (equity consideration plus net debt) ("Levered

                                       27

Consideration") to sales, EBITDA and earnings before interest expense and income
taxes ("EBIT") for the Food Equipment Industry Selected Transactions for which
the relevant information to make such calculations was publicly available. The
ranges, medians and means of such multiples for such transactions are set forth
in the following table:

     Goldman Sachs also reviewed the financial terms, to the extent publicly
available, of selected pending or completed mergers and acquisitions
transactions since October 1992 involving general industrial companies (the
"General Industrial Selected Transactions"). Goldman Sachs based this analysis
on publicly available information for each of the General Industrial Selected
Transactions. The transactions involved were: Allied Signal/Honeywell; B.F.
Goodrich/Coltec Industries; General Electric/Reltec; Eaton/ Aeroquip-Vickers;
Tyco International/AMP; United Technologies/Sundstrand; Siebe/BTR; ABB
Transportation/Elsag Bailey Process; SPX/General Signal; Framatome Connectors
International/Berg Electronics; Continental AG/ITT Industries -- Automotive
Brake and Chassis Division; Schlumberger Technology/Camco International; United
States Filter/Culligan Water Technologies; B.F. Goodrich/Rohr;
Ingersoll-Rand/Thermo King; KKR/Amphenol; Tyco International/Keystone
International; Ingersoll-Rand/Clark Equipment; Rockwell/Reliance Electric; and
Emerson Electric/Fisher Controls International. Goldman Sachs calculated the
multiples of Levered Consideration to sales, EBITDA and EBIT, as well as the
premiums (based on the premiums of the average 30-day trading price (prior to
announcement)) for such General Industrial Selected Transactions for which the
relevant information to make such calculations was publicly available. The
ranges, medians and means of such multiples and the premiums are set forth in

     Analysis of Implied Transaction Multiples. Goldman Sachs also reviewed
certain implied multiples for the merger, each based on a price per share of
Premark common stock of $55.00. Such implied transaction multiples included: (1)
Levered Consideration as a multiple of revenues, EBITDA and EBIT, and (2) equity
value as a multiple of net income. The following table presents the values of
such multiples:

     Estimates of revenues, EBITDA, EBIT and net income in the foregoing tables
are based on Premark management estimates. Equity values are calculated on a
fully-diluted basis, including options and share equivalents. Levered
Consideration includes net debt as of June 30, 1999.

     Discounted Cash Flow Analysis. Based on internal estimates of the
management of Premark, Goldman Sachs performed a discounted cash flow analysis
of Premark on a stand-alone basis. The estimated future cash flows were based on
the financial projections for Premark for the years 1999 through 2002. The
terminal values of Premark were calculated based on projected EBITDA multiples
for 2002 of 6.0x to 10.0x and a range of discount rates of 10.0% to 14.0%. Based
on these parameters, Goldman Sachs calculated Premark's per share equity value
to range from $36.34 to $64.76.

     Contribution Analysis. Goldman Sachs analyzed the relative contributions of
Premark and Illinois Tool Works to the pro forma income statement of the
combined company, based, in the case of Premark, on management projections and,
in the case of Illinois Tool Works, on various research reports. The analysis
showed that on a pro forma combined basis (excluding (1) the effect of any
synergies of the merger and (2) non-recurring expenses relating to the merger)
Premark and Illinois Tool Works would account for approximately the following
percentages of the combined company for the following:

     The preparation of a fairness opinion is a complex process involving
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of these methods to the particular
circumstances and, therefore, is not necessarily susceptible to partial analysis
or summary description. Selecting portions of the analyses or of the summary set
forth above, without considering the analysis as a whole, could create an
incomplete view of the processes underlying Goldman Sachs' opinion. In arriving
at its fairness determination, Goldman Sachs considered the results of all such
analyses and did not attribute any particular weight to any factor or analysis
considered by it; rather, Goldman Sachs made its determination as to fairness on
the basis of its experience and professional judgment after considering the
results of all such analyses. No company or transaction used in the above
analyses is directly comparable to Premark or the contemplated transaction. The
analyses were prepared solely for purposes of Goldman Sachs providing its
opinion to the Premark board of directors as to the fairness of the exchange
ratio and do not purport to be appraisals or necessarily reflect the prices at
which businesses or securities actually may be sold. Analyses based on forecasts
of future results are not necessarily indicative of actual future results, which
may be significantly more or less favorable than suggested by such analyses.
Because such analyses are inherently subject to uncertainty, being based upon
numerous factors or events beyond the control of the parties or their respective
advisors, none of Premark, Goldman Sachs or any other

                                       29
<PAGE>   36

person assumes responsibility if future results are materially different from
those forecast. As described above, the opinion of Goldman Sachs to the Premark
board of directors was among many factors taken into consideration by the
Premark board of directors in making its determination to approve the merger
agreement.

     Pursuant to Goldman Sachs' engagement letter, Premark has agreed to pay
Goldman Sachs, as compensation for Goldman Sachs' services as financial advisor
to Premark in connection with the merger, a transaction fee equal to $14.0
million payable at the effective time of the merger. Premark has also agreed to
pay Goldman Sachs its reasonable out-of-pocket expenses, including the fees and
disbursements of its attorneys, and to indemnify Goldman Sachs against certain
liabilities, including certain liabilities arising under the federal securities
laws.

                            ------------------------

     Set forth below is a summary of the material terms of the merger agreement.
This summary is qualified in its entirety by reference to the merger agreement.
A copy of the merger agreement is attached as Annex A to this proxy
statement/prospectus and is incorporated in this proxy statement/prospectus by
reference. You should read the merger agreement because it, and not this proxy
statement/prospectus, is the legal document that governs the merger.

STRUCTURE OF THE MERGER

     At the effective time of the merger, Merger Sub will merge with and into
Premark and the separate corporate existence of Merger Sub will end. Premark
will be the surviving corporation in the merger and will be a wholly owned
subsidiary of Illinois Tool Works.

WHEN THE MERGER BECOMES EFFECTIVE

     On the second business day following the date the last of the closing
conditions to the merger is fulfilled or waived, or such other time and date as
Illinois Tool Works and Premark may agree, we will file a certificate of merger
with the Delaware Secretary of State. The merger will become effective at the
time and on the date on which we file the certificate of merger or such other
time upon which we agree and specify in the certificate of merger. That time is
the "effective time of the merger."

CONVERSION OF STOCK, STOCK OPTIONS AND OTHER AWARDS

     At the effective time of the merger, each share of Premark common stock
issued and outstanding immediately prior to the effective time of the merger
(but not including shares of Premark common stock that are owned by Illinois
Tool Works, Merger Sub or any other direct or indirect subsidiary of Illinois
Tool Works or shares of Premark common stock that are owned by Premark or any
direct or indirect subsidiary of Premark) will be converted into and become
exchangeable for the fraction of a share of Illinois Tool Works common stock
equal to:

     - if the Illinois Tool Works average price is equal to or greater than
       $66.33 but less than or equal to $89.73, the result, calculated to four
       decimal places, of $55.00 divided by the Illinois Tool Works average
       price;

     - if the Illinois Tool Works average price is greater than $89.73 but less
       than $101.44, the result, calculated to four decimal places, of

       [$55.00 + {.3065 (Illinois Tool Works average price - $89.73)}] /
       Illinois Tool Works average price;

     - if the Illinois Tool Works average price is less than $66.33 but greater
       than $54.62, the result, calculated to four decimal places, of

       [$55.00 - {.4146 ($66.33 - Illinois Tool Works average price)}] /
       Illinois Tool Works average price;

     - .5776 if the Illinois Tool Works average price is greater than or equal
       to $101.44; or

     - .9181 if the Illinois Tool Works average price is less than or equal to
       $54.62.

                                       30
<PAGE>   37

     For purposes of these calculations, "the Illinois Tool Works average price"
means the average of the closing price per share of Illinois Tool Works common
stock on the New York Stock Exchange, as reported in The Wall Street Journal,
New York City edition, on the 20 New York Stock Exchange trading days ending on
the second business day before the effective time of the merger. The Illinois
Tool Works average price will be rounded to the nearest cent.

     If, before the effective time of the merger, Illinois Tool Works or Premark
declares or effects a reclassification, stock split (including a reverse split),
or stock dividend or stock distribution with respect to its shares, or a stock
dividend or stock distribution, or any similar transaction occurs relating to
its shares, the exchange ratio will be equitably adjusted to reflect that event.

     Each option to purchase Premark common stock granted under Premark's stock
plans that is outstanding and unexercised at the time the Premark stockholders
adopt the merger agreement will vest and, if not exercised prior to the
effective time of the merger, will be converted automatically at the effective
time of the merger into a vested option to purchase the same number of shares of
Illinois Tool Works common stock as the holder of the option would have been
entitled to receive in the merger had the holder exercised the option
immediately prior to the merger. After conversion, the exercise price per
Illinois Tool Works common share subject to each option will equal its
pre-conversion exercise price per share of Premark common stock, divided by the
number equal to the fraction of a share of Illinois Tool Works common stock to
be issued for each share of Premark common stock.

the differences between the rights of holders of Illinois Tool Works common
stock and Premark common stock, see "Comparison of Rights of Illinois Tool Works
Stockholders and Premark Stockholders."

FRACTIONAL SHARES

     No fractional shares of Illinois Tool Works common stock will be issued in
the merger. Instead of issuing fractional shares of Illinois Tool Works common
stock, Illinois Tool Works will pay cash, without interest, in an amount equal
to such fraction, rounded to the nearest one-hundredth of a share, multiplied by
the average closing price per share of Illinois Tool Works common stock as
reported in The Wall Street Journal, New York City edition, on the five trading
days immediately before the effective time of the merger.

EXCHANGE PROCEDURES

     At or prior to the effective time of the merger, Illinois Tool Works will
deposit with the exchange agent, Harris Trust and Savings Bank, in trust for the
benefit of the holders of Premark shares, certificates representing shares of
Illinois Tool Works common stock issuable under the merger agreement and an
amount of cash sufficient to pay cash in lieu of fractional shares. Illinois
Tool Works will make sufficient funds available to the exchange agent from time
to time as needed to pay cash in respect of dividends or other distributions on
unexchanged shares.

     If you have a Premark stock certificate, then promptly after the merger
takes place, but in no event later than three business days following the date
of the merger, Harris Trust and Savings Bank will send you a letter of
transmittal for you to use in exchanging your Premark common stock certificates
for certificates representing shares of Illinois Tool Works common stock. YOU
SHOULD NOT SEND IN YOUR PREMARK COMMON STOCK CERTIFICATES UNTIL YOU RECEIVE THE
LETTER OF TRANSMITTAL. If you own Premark common stock through a broker,
Premark's employee benefit plans or other arrangement where you do not hold a
Premark certificate, then your stock certificates will be exchanged for
certificates representing Illinois Tool Works common stock and cash in lieu of
fractional shares based on the exchange ratio without any action by you.

                                       31
<PAGE>   38

     If any certificates for shares of Illinois Tool Works common stock are to
be issued in a name other than that in which the Premark stock certificate
surrendered in exchange therefor is registered, the person requesting such
exchange must (1) pay any transfer or other taxes required by reason thereof or
(2) establish to the satisfaction of Illinois Tool Works or Harris Trust and
Savings Bank that such tax has been paid or is not applicable.

     Harris Trust and Savings Bank will deduct and withhold from the
consideration otherwise payable pursuant to the merger agreement such amounts as
Harris Trust and Savings Bank is required to deduct and withhold under the
Internal Revenue Code, or any provision of state, local or foreign tax law, with
respect to the making of such payment. To the extent that amounts are withheld
by Harris Trust and Savings Bank, the withheld amounts shall be treated for
purposes of the merger agreement as having been paid to the person in respect of
whom the deduction and withholding was made by Harris Trust and Savings Bank.

     If Illinois Tool Works declares a dividend or distribution with a record
date at or after the effective time of the merger, the declaration will include
dividends and distributions in respect of shares of Illinois Tool Works common
stock issued in the merger. If you have a Premark stock certificate, until you
surrender that certificate for exchange after the effective time of the merger,
you will not be paid dividends or other distributions declared with a record
date after the effective time of the merger, but with a payment date on or
before you surrender your certificate, with respect to shares of Illinois Tool
Works common stock into which your shares of Premark common stock have been
converted. When you surrender your certificates, any such unpaid dividends or
other distributions will be paid to you, subject to applicable abandoned
property, escheat or similar laws. No interest will be paid or accrued on cash
to be paid instead of fractional shares, unpaid dividends or distributions, if
any, payable to holders of Premark common stock certificates. Registered holders
of unsurrendered Premark common stock certificates, subject to applicable
abandoned property, escheat or similar laws, will be entitled to vote after the
effective time of the merger at any meeting of Illinois Tool Works stockholders
with a record date at or after the effective time of the merger the number of
whole shares of Illinois Tool Works common stock represented by such Premark
common stock certificates, regardless of whether such holders have exchanged
their Premark common stock certificates. None of Illinois Tool Works, Premark or
Harris Trust and Savings Bank, or any other person, will be liable to any former
holder of Premark common stock for any amount properly delivered to a public
official pursuant to applicable abandoned property, escheat or similar laws.

     After the effective time of the merger, there will be no transfers on the
Premark stock transfer books of shares of Premark common stock. If, after the
effective time, valid Premark stock certificates are presented to the surviving
corporation for any reason, they will be canceled and exchanged as described
above to the extent allowed by applicable law.

     If a certificate for Premark common stock has been lost, stolen or
destroyed, Illinois Tool Works will issue the consideration properly payable in
accordance with the merger agreement upon receipt of an affidavit of the
claimant to the effect that the certificate has been lost, stolen or destroyed,
and (1) a reasonable undertaking to indemnify Illinois Tool Works or Premark, if
Illinois Tool Works believes that the person providing the indemnity is
sufficiently creditworthy, or (2) the posting by the claimant of an indemnity
bond customarily required by Illinois Tool Works, in each case in respect of the
certificate at issue.

period between September 9, 1999 and the effective time of the merger with
respect to:

     - charter and bylaw amendments;

     - changes in capital stock and payment of dividends; and

     - actions that would affect the accounting or tax treatment of the merger.

     Illinois Tool Works and Premark have agreed that until the effective time
of the merger, they will each use the last day of Illinois Tool Works'
then-current fiscal quarter as the record date for determining the stockholders
entitled to receive any regular quarterly dividends they may pay for that
quarter.

NON-SOLICITATION OF COMPETING PROPOSALS

     Premark has agreed to a number of restrictions concerning "acquisition
proposals," which the merger agreement defines generally as proposals to merge
or combine with Premark or to acquire 15% or more of Premark's stock or assets.
Specifically, Premark has agreed that neither it nor its agents will, directly
or indirectly,

     - initiate, solicit, knowingly encourage or intentionally facilitate the
       making of any acquisition proposal;

     - provide any confidential information to a third party in connection with
       an acquisition proposal; or

     - engage in any negotiations concerning an acquisition proposal.

     The merger agreement expressly allows Premark to comply with Securities and
Exchange Commission rules regarding the publication of a board of directors'
recommendations with respect to tender offers, and, subject to some limitations,
expressly allows Premark's board of directors

     - to negotiate with, and provide information to, third parties when
       Premark's board of directors determines in good faith, after consultation
       with outside counsel, that it should do so to comply with its fiduciary
       duties; and

     - to recommend a "superior proposal" to Premark stockholders, a "superior
       proposal" being defined generally as an acquisition proposal that
       Premark's board of directors concludes in good faith, after consulting
       its legal and financial advisors, is reasonably capable of being
       completed, and, if completed, would be more favorable to Premark
       stockholders than the merger with Illinois Tool Works.

     Except as permitted by Illinois Tool Works, Premark has agreed to terminate
all existing discussions and negotiations with third parties concerning
acquisition proposals. Premark has agreed to notify Illinois Tool Works as soon
as reasonably practicable if it receives any acquisition proposal or if a third
party seeks

                                       34
<PAGE>   41

information from it or seeks to engage it in discussions concerning an
acquisition proposal. Premark has also agreed to keep Illinois Tool Works
informed of any such proposals or inquiries on an ongoing basis.

STOCKHOLDERS MEETINGS

     The merger agreement requires both companies to convene their respective
stockholder meetings as soon as reasonably practicable.

     Premark has agreed that its board of directors will recommend that Premark
stockholders vote to adopt the merger agreement. Premark's board of directors
may withdraw or modify its recommendation if it determines in good faith, after
consultation with outside legal counsel, that failing to do so would be
reasonably likely to be inconsistent with its fiduciary duties.

     Illinois Tool Works has agreed that its board of directors will recommend
that Illinois Tool Works stockholders vote to approve the issuance of stock
necessary to complete the merger. The merger agreement allows Illinois Tool
Works to cancel the meeting of its stockholders if, under the rules of the New
York Stock Exchange, the issuance can be completed without stockholder approval.
Two affiliates of Illinois Tool Works, Harold Smith and Robert McCormack, have
agreed to vote their shares of Illinois Tool Works stock in favor of the
issuance if a vote is required. Those affiliates have also agreed to use all
reasonable efforts, subject to their fiduciary duties as trustees, to cause the
trusts as to which they act as trustees to vote the shares of Illinois Tool
Works stock directly owned by such trusts in favor of the issuance if a vote
takes place.

FILINGS AND OTHER ACTIONS

     Illinois Tool Works and Premark have agreed to cooperate with each other,
and to use their reasonable best efforts:

     - to take all necessary, proper and advisable actions to complete the
       merger, including obtaining comfort letters from their respective
       independent public accountants and opinions from their respective
       attorneys, preparing and filing promptly all documentation necessary to
       complete the merger, and instituting any court action necessary to obtain
       approval of the merger and defending any court action instituted to
       prevent completion of the merger; and

     - to obtain promptly all approvals necessary or advisable to complete the
       merger.

     The merger agreement provides that Premark will not commit to any
divestitures, licenses, hold separate arrangements or similar matters without
Illinois Tool Works' permission, and will, at Illinois Tool Works' request, use
its reasonable best efforts to effect any divestitures, licenses, hold separate
arrangements or similar matters, so long as they are contingent upon completion
of the merger. The merger agreement also provides that Illinois Tool Works will
not be required to agree to any divestitures, licenses, hold separate
arrangements or similar matters if doing so would reasonably be expected to have
a material adverse effect on either Illinois Tool Works or Premark.

     Illinois Tool Works has agreed to limit its participation in business
combination transactions before the merger. Illinois Tool Works may participate
in such a transaction if:

     - the fair market value of the consideration paid by Illinois Tool Works in
       the transaction does not exceed $750 million;

     - the aggregate fair market value of the consideration paid by Illinois
       Tool Works in all such transactions does not exceed $1.5 billion; and

     - Illinois Tool Works believes that the transaction is not reasonably
       likely to prevent or delay satisfaction of any of the conditions to the
       merger.

     The $750 million and $1.5 billion limits may be exceeded with the consent
of Premark's chief executive officer.

                                       35
<PAGE>   42

     If Illinois Tool Works participates in a business combination transaction
other than with Premark, it must agree to any divestitures, licenses, hold
separate arrangements or similar matters necessary to obtain approval of the
Premark merger under applicable antitrust laws.

EMPLOYEE BENEFIT MATTERS

     After the effective time of the merger, Illinois Tool Works will ensure
that the Premark compensation and benefit plans in effect immediately before the
effective time of the merger are maintained, but it may cause the amendment or
termination of any such plan to the extent permitted by its terms or applicable
law. The merger agreement further provides that, under circumstances described
in the merger agreement, Premark employees will receive credit under Illinois
Tool Works benefit plans in which they participate for their years of service
with Premark prior to the merger and Illinois Tool Works will cause all
"pre-existing conditions" exclusions and "actively-at-work" requirements under
its medical and other related plans to be waived.

       a significant amount of business on a combined basis;

     - the absence of any stop order suspending the effectiveness of Illinois

       independent public accountants regarding the accounting treatment of the
       merger.

The conditions to Illinois Tool Works' obligation to complete the merger
include:

       and warranties;

     - Premark's performance in all material respects of all its pre-merger
       obligations under the merger agreement; and

                                       36
<PAGE>   43

The conditions to Premark's obligation to complete the merger include:

     - the accuracy, as qualified for materiality, of Illinois Tool Works'
       representations and warranties;

     - Illinois Tool Works' performance in all material respects of all its
       pre-merger obligations under the merger agreement; and

     At any time before the effective time of the merger, Illinois Tool Works or
Premark may waive any of these conditions without the approval of their
respective stockholders. As of the date of this proxy statement/prospectus,
neither company expects to waive any condition.

INDEMNIFICATION AND INSURANCE

     Illinois Tool Works has agreed that:

     - it will, and will cause Premark to, indemnify each present and former
       director or officer of Premark against any costs or expenses incurred in
       connection with any proceeding or investigation pertaining to matters
       occurring at or before the effective time of the merger relating to the
       services the indemnified party performed for Premark;

     - it will cause Premark to provide similar indemnification to each present
       and former director or officer of any subsidiary or division of Premark

       September 9, 1999; and

     - it will cause Premark to maintain, for at least six years, a policy of
       officers' and directors' liability insurance covering the indemnified

       policy in place on September 9, 1999, subject to a cap on the cost of the
       policy of twice the cost of the last premium Premark paid under the
       policy in place on September 9, 1999.

TERMINATION OF THE MERGER AGREEMENT

     Illinois Tool Works and Premark can agree to terminate the merger agreement
at any time without completing the merger.

     Also, either Illinois Tool Works or Premark can, without the consent of the
other, terminate the merger agreement:

     - if the merger is not completed before the "termination date," which is
       defined in the merger agreement as April 9, 2000, or July 8, 2000 if
       extended by either party solely because such extension is necessary in
       order to obtain governmental approvals of the merger under applicable
       competition laws and if all other conditions to completion of the merger
       are satisfied or are capable of being satisfied. The merger agreement may
       not be terminated pursuant to this provision if the merger is not
       completed because the party that wants to terminate the merger agreement
       has materially breached the merger agreement;

     - if the Premark meeting is held and Premark stockholders do not adopt the
       merger agreement;

     - if the listing requirements of the New York Stock Exchange require the
       issuance of Illinois Tool Works shares in the merger to be approved, the
       Illinois Tool Works meeting is held, and Illinois
                                       37
<PAGE>   44

       Tool Works' stockholders do not approve the issuance of the Illinois Tool
       Works shares in the merger;

     - if any order permanently restraining, enjoining or otherwise prohibiting
       completion of the merger has become final and non-appealable; or

     - if the other party materially breaches the merger agreement and cannot or
       does not correct the breach before the termination date.

     In addition, Premark can terminate the merger agreement before the
effective time of the merger if Premark receives an unsolicited proposal for a
business combination transaction with a third party that Premark's board of
directors concludes is a superior proposal and Premark gives Illinois Tool Works
at least four business days notice of its intention to enter into an agreement
for such superior proposal and, during that four business day period, Premark
considers any adjustment in the terms of the merger agreement that Illinois Tool
Works may propose.

     Finally, Illinois Tool Works can terminate the merger agreement if
Premark's board of directors withdraws or materially modifies or changes in a
manner adverse to Illinois Tool Works its approval or recommendation of the
merger or the merger agreement.

  Termination Fee

     Premark must pay Illinois Tool Works a fee of $75 million in cash if the
merger agreement is terminated:

     - by either Illinois Tool Works or Premark following completion of the
       Premark stockholders meeting held to consider the merger agreement on the
       basis that Premark stockholders have not adopted the merger agreement,
       and:

        -- a third party has made, and not withdrawn, an acquisition proposal to
           Premark; and

        -- Premark's board of directors has withdrawn or materially modified, in
           a manner adverse to Illinois Tool Works, its approval or
           recommendation of the merger;

     - by Illinois Tool Works on the ground that Premark's board of directors
       has withdrawn or modified its approval or recommendation of the merger in
       a manner adverse to Illinois Tool Works to such an extent that it is no
       longer approving or recommending the merger agreement or the merger;

     - by either Illinois Tool Works or Premark following completion of the
       Premark stockholders meeting held to consider the merger agreement on the
       basis that Premark stockholders have not adopted the merger agreement,
       and

        -- a third party has made, and not withdrawn, an acquisition proposal to
           Premark; and

        -- within one year of the termination of the merger agreement, Premark
           enters into a definitive agreement with respect to an acquisition
           proposal, or an acquisition proposal has been completed; or

     - by Premark, at any time before the adoption of the merger agreement by
       Premark stockholders, because of a superior proposal.

     For purposes of the termination fee provisions of the merger agreement, an
"acquisition proposal" includes any proposal or offer with respect to any
purchase or sale of the consolidated assets of Premark or any of its
subsidiaries, taken as a whole, having an aggregate value of 50% or more of
Premark's market capitalization, or any purchase or sale of, or tender offer
for, 50% or more of its equity securities.

     The termination fee described above is in addition to any profit Illinois
Tool Works may receive under the stock option agreement.

                                       38
<PAGE>   45

EXPENSES

     Illinois Tool Works will pay the expenses in connection with the
registration fees paid to the Securities and Exchange Commission, printing and
mailing this proxy statement/prospectus and other filing fees. Illinois Tool
Works and Premark will pay their own expenses in connection with the merger and
the related transactions, except as described above.

MODIFICATION OR AMENDMENT TO THE MERGER AGREEMENT

     At any time prior to the effective time, Illinois Tool Works and Premark
can modify or amend the merger agreement if they both agree to do so. Each can
waive its right to require the other to comply with the merger agreement where
the law allows.

REGULATORY REQUIREMENTS

     Under the Hart-Scott-Rodino Act and the rules promulgated thereunder by the
Federal Trade Commission, the merger cannot be completed until notifications
have been given and certain information has been furnished to the Federal Trade
Commission and the Antitrust Division of the Department of Justice and specified
waiting period requirements have been satisfied. Illinois Tool Works and Premark
filed notification and report forms under the Hart-Scott-Rodino Act with the
Federal Trade Commission and the Antitrust Division on September 24, 1999. The
waiting period under the Hart-Scott-Rodino Act will expire at 11:59 p.m.,
Eastern Time, on October 24, 1999, unless a request for additional information
or documentary material by the Department of Justice or Federal Trade Commission
is made before that time or the waiting period is terminated earlier.

     At any time before or after completion of the merger, the Antitrust
Division or the Federal Trade Commission or any state could take such action
under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the completion of the merger, to rescind
the merger or to seek divestiture of particular assets of Illinois Tool Works or
Premark. Private parties also may seek to take legal action under the antitrust
laws under certain circumstances. In addition, non-United States governmental
and regulatory authorities may seek to take action under applicable antitrust
laws. A challenge to the merger on antitrust grounds may be made and, if such a
challenge is made, it is possible that Illinois Tool Works and Premark will not
prevail.

     Premark and Illinois Tool Works each conducts business in member states of
the European Union. Council Regulation (ECC) 4064/89, as amended, requires
notification to and approval by the European Commission of mergers or
acquisitions involving parties with aggregate worldwide sales and individual
European Union sales exceeding specific thresholds before these mergers or
acquisitions are implemented. Premark and Illinois Tool Works intend to file a
merger notification with the European Union antitrust authorities as soon as
practicable.

     The European Commission must review the merger to determine whether or not
it is compatible with the common market and, accordingly, whether or not to
permit it to proceed. A merger or acquisition that does not create or strengthen
a dominant position that would significantly impede effective competition in the
common market or in a substantial part of it shall be declared compatible with
the common market and must be allowed to proceed. If, following a preliminary
one-month Phase I investigation, the European Commission determines that it
needs to examine the merger more closely because it raises serious doubts as to
its compatibility with the common market, it must initiate Phase II
investigation procedures. If it initiates a Phase II investigation, the European
Commission must issue a final decision as to whether or not the merger is
compatible with the common market no later than four months after the initiation
of the Phase II investigation.

     Premark and Illinois Tool Works conduct operations in a number of
jurisdictions where other regulatory filings or approvals may be required or
advisable in connection with the completion of the merger. Premark and Illinois
Tool Works are currently reviewing whether filings or approvals may be required
or desirable in those jurisdictions that may be material to Premark and Illinois
Tool Works and

                                       39
<PAGE>   46

their subsidiaries. It is possible that one or more of these filings may not be
made, or one or more of these approvals may not be obtained prior to the merger.

     Regulatory agencies enforcing antitrust and similar laws could delay,
oppose or refuse to approve the merger or impose conditions that could have an
adverse effect on the combined company.

MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion summarizes the material U.S. federal income tax
considerations of the merger. This summary is based on the Internal Revenue
Code, applicable U.S. Treasury Regulations, judicial authority, and
administrative rulings and practice, all in effect on the date of this proxy
statement/prospectus, all of which are subject to change, possibly with
retroactive effect. This summary does not purport to be a complete discussion of
all U.S. federal income tax consequences of the merger. The discussion below
does not address any state, local or foreign tax consequences of the merger or
any federal tax consequences other than federal income tax consequences. In
addition, this discussion does not address all of the U.S. federal income tax
consequences that may be relevant to particular stockholders in light of their
individual circumstances and may not apply, in whole or in part, to particular
stockholders, such as individuals who hold options in respect of Premark common
stock or who have acquired Premark common stock under a compensatory or other
employment-related arrangement, insurance companies, tax-exempt organizations,
mutual funds, financial institutions or broker-dealers, non-United States
persons, traders in securities that elect to mark-to-market, and persons who
hold Premark common stock as part of a hedge, straddle, constructive sale or
conversion transaction. The following discussion assumes that Premark common
stock is held by the relevant stockholder as a capital asset at the effective
time of the merger.

     PREMARK STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES OF THE MERGER TO THEM, INCLUDING THE APPLICABILITY
AND EFFECT OF ANY STATE, LOCAL OR FOREIGN LAWS, AND THE EFFECT OF POSSIBLE
CHANGES IN APPLICABLE TAX LAWS.

  General

     The obligations of Premark and Illinois Tool Works, respectively, to
complete the merger are conditioned upon the receipt by Premark of the opinion
of Wachtell, Lipton, Rosen & Katz and the receipt by Illinois Tool Works of the
opinion of Mayer, Brown & Platt, each dated the closing date of the merger, that
the merger will be treated for federal income tax purposes as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code and that each
of Illinois Tool Works, Merger Sub and Premark will be a party to that
reorganization within the meaning of Section 368(b) of the Internal Revenue
Code. The tax opinions will be based upon certain facts, customary assumptions
and customary representations made by Illinois Tool Works, Merger Sub and
Premark, including representations in certificates to be delivered to counsel by
the management of each of Illinois Tool Works and Premark that, if incorrect in
material respects, would jeopardize the conclusions reached by counsel in their
respective opinions. Neither Illinois Tool Works nor Premark has requested nor
will request an advance ruling from the Internal Revenue Service as to the tax
consequences of the merger and there can be no assurance that the Internal
Revenue Service will agree with the conclusions set forth in this proxy
statement/prospectus or the opinions. The discussion below assumes that the
merger qualifies as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code.

  Tax Treatment to Premark, Illinois Tool Works and Merger Sub

     No gain or loss will be recognized by Premark, Illinois Tool Works or
Merger Sub as a result of the merger.

  Tax Treatment to Holders of Premark Common Stock

     Except with respect to any cash received instead of fractional shares, a
Premark stockholder will not recognize any gain or loss for federal income tax
purposes as a result of the exchange of Premark common
                                       40
<PAGE>   47

stock solely for shares of Illinois Tool Works common stock pursuant to the
merger. A Premark stockholder's aggregate tax basis for the shares of Illinois
Tool Works common stock received pursuant to the merger, including any
fractional share interest for which cash is received, will equal such
stockholder's aggregate tax basis in shares of Premark common stock held
immediately before the merger. A Premark stockholder's holding period for the
shares of Illinois Tool Works common stock received pursuant to the merger,
including any fractional share interest for which cash is received, will include
the period during which the shares of Premark common stock were held.

     A holder of Premark common stock that receives cash instead of a fractional
share of Illinois Tool Works common stock in the merger generally will recognize
a capital gain or loss in an amount equal to the difference between the amount
of cash received and such holder's adjusted tax basis allocable to such
fractional share. In the case of an individual stockholder, any such capital
gain or loss generally will be subject to a maximum United States federal income
tax rate of 20 percent if the individual has held his or her Premark common
stock for more than one year on the date of the merger. The deductibility of
capital losses is subject to limitations for both individuals and corporations.
Notwithstanding the foregoing, it is possible that, in the case of certain
holders of Premark common stock who after the merger own directly or
constructively more than a minimal amount of Illinois Tool Works common stock,
exercise control over Illinois Tool Works or, in addition to direct ownership,
own Illinois Tool Works stock under certain constructive ownership rules, the
cash received instead of a fractional share may be taxed as a dividend.

  Tax Treatment to Holders of Illinois Tool Works Common Stock

     Holders of Illinois Tool Works common stock will not recognize any gain or
loss for federal income tax purposes as a result of the merger.

ANTICIPATED ACCOUNTING TREATMENT

     The merger is intended to qualify as a "pooling-of-interests" for
accounting purposes. Under that method of accounting, the recorded historical
cost basis of the assets and liabilities of Illinois Tool Works and Premark will
be carried forward to the combined company. Results of operations of the
combined company will include income of Illinois Tool Works and Premark for the
entire fiscal period in which the combination occurs, and the historical results
of operations of the separate companies for fiscal years before the merger will
be combined and reported as the results of operations of the combined company.

     Completion of the merger is conditioned upon:

     - Illinois Tool Works' receipt of a letter from its independent public
       accountants to the effect that the merger should qualify for
       "pooling-of-interests" accounting treatment; and

     - Premark's receipt of a letter from its independent public accountants to
       the effect that Premark is a poolable entity.

     See "-- Conditions to Completion of the Merger." However, some of the
conditions to be met to qualify for "pooling-of-interests" accounting treatment
cannot be fully assessed until specific periods of time after the effective time
of the merger have passed, because some of the conditions for "pooling-of-
interests" accounting treatment address transactions occurring within those
specific periods of time. A number of events, including certain transactions
with respect to Illinois Tool Works common stock or Premark common stock by
affiliates of Illinois Tool Works and Premark, respectively, could prevent the
merger from qualifying as a "pooling-of-interests" for accounting purposes. For
information concerning restrictions to be imposed on the transferability of
Illinois Tool Works common stock to be received by affiliates in order, among
other things, to ensure the availability of "pooling-of-interests" accounting
treatment, see "-- Resale Restrictions."

     If, after completion of the merger, events occur that cause the merger to
be deemed no longer to qualify for "pooling-of-interests" accounting treatment,
the purchase method of accounting would be applied. The purchase method of
accounting would have a material adverse effect on the reported

                                       41
<PAGE>   48

operating results of Illinois Tool Works as compared to "pooling-of-interests"
accounting treatment. See "Risk Factors -- Failure to qualify for
"pooling-of-interests" accounting treatment would negatively impact reported
operating results."

RESALE RESTRICTIONS

  Restrictions Imposed by Rule 145

     All Illinois Tool Works common stock received by Premark stockholders in
the merger will be freely transferable, except that shares of Illinois Tool
Works common stock received by persons who are deemed to be "affiliates" (as
such term is defined under the Securities Act of 1933) of Premark may be resold
by them only in transactions permitted by the resale provisions of Rule 145 (or
Rule 144 in the case of such persons who become affiliates of Illinois Tool
Works) promulgated under the Securities Act of 1933 or as otherwise permitted
under the Securities Act of 1933. Persons who may be deemed to be affiliates of
Illinois Tool Works or Premark generally include individuals or entities that
control, are controlled by or are under common control with such party and may
include certain officers and directors of Illinois Tool Works or Premark, as
well as significant stockholders.

  Restrictions Related to "Pooling-of-Interests" Accounting Treatment

     Guidelines regarding qualification for the use of the
"pooling-of-interests" method of accounting also limit sales of capital stock by
affiliates of the acquiring and acquired companies in a business combination.
These guidelines indicate further that the "pooling-of-interests" method of
accounting generally will not be challenged on the basis of sales of capital
stock by affiliates of the acquiring or acquired company if they do not reduce
the risk of holding any of the shares they own or shares they receive in
connection with a merger during the period beginning 30 days before the merger
and ending when financial results covering at least 30 days of post-combination
results of operations have been published. See "-- Anticipated Accounting
Treatment."

     Under the merger agreement, Premark is required to use all reasonable
efforts to cause each of its affiliates to execute a written agreement
restricting the disposition by such affiliate of the shares of Illinois Tool
Works common stock to be received by such affiliate in the merger. Premark has
agreed not to register the transfer of any certificate unless such transfer is
made in compliance with the foregoing. Also under the merger agreement, Illinois
Tool Works is required to use all reasonable efforts to cause each of its
affiliates to execute a written agreement restricting the disposition by such
affiliate of any shares of Illinois Tool Works common stock.

INTERESTS OF PREMARK DIRECTORS AND OFFICERS IN THE MERGER THAT ARE DIFFERENT
FROM PREMARK STOCKHOLDERS' INTERESTS

     In considering the recommendation of Premark's board of directors with
respect to the merger, stockholders should be aware that some of the members of
Premark's board of directors and some of Premark's officers have interests in
the merger that are different from the interests of stockholders of Premark
generally.

     - All outstanding options granted by Premark to purchase Premark common
       stock, including those held by officers and directors of Premark, will
       vest upon approval of the merger by Premark stockholders, and, if not
       exercised by the effective time of the merger, will be converted into
       vested options to purchase shares of Illinois Tool Works common stock,
       which will be adjusted in accordance with the exchange ratio. Based upon
       the options outstanding as of October 11, 1999, options held by Premark's
       officers and directors relating to 1,069,750 shares of Premark common
       stock will vest upon approval of the merger by Premark stockholders.

     - Restrictions on restricted stock awards granted to employees of Premark
       will lapse upon adoption of the merger agreement by Premark stockholders,
       and, at the effective time of the merger, those shares will be converted
       into unrestricted shares of Illinois Tool Works common stock in
       accordance with the exchange ratio.

                                       42
<PAGE>   49

     - Premark's executive officers are each covered by individual employment
       agreements with Premark and by Premark benefit plans containing change of
       control provisions that become operative upon approval of the merger by
       Premark stockholders. If, after the merger, such executive's employment
       is terminated (1) without "cause" or by the affected executive for "good
       reason" or (2) for any reason during a 30-day period commencing on the
       first anniversary of the merger, the executive is entitled to the
       following severance benefits:

        -- three times the executives' annual base salary and annual and
           long-term incentive awards;

        -- specified annual and long-term awards;

        -- lifetime medical benefits and continuation of other welfare benefits
           for three years; and

        -- an additional payment to the extent necessary to make the executive
           whole for any excise tax imposed as a result of receiving "excess
           parachute payments."

       We estimate that if each executive officer were terminated without cause
       immediately after the merger, the cash payments due, including with
       respect to the excise tax, would be $50.7 million (assuming that the
       merger occurred before December 31, 1999 and that the value of the
       Premark common stock immediately before the merger was $55 per share).

     - W. James Farrell, chairman and chief executive officer of Illinois Tool
       Works, is a director of Premark. Mr. Farrell did not take part in, and
       was not present during, any of the deliberations of Premark's board of
       directors concerning the merger or the merger agreement.

     - It is expected that James M. Ringler, Premark's chairman, chief executive
       officer and president, will assume a senior management role with Illinois
       Tool Works after the merger.

     Premark's board of directors was aware of these interests and considered
them, among other matters, when approving the merger.

     Illinois Tool Works intends to offer agreements to Mr. Ringler, William
Reeb, president of Wilsonart, a subsidiary of Premark, and possibly other
Premark executives who have not yet been designated in order to induce these
executives to stay with the combined company. The terms of these agreements have
not yet been determined. Illinois Tool Works may also make payments to some
Premark executives in exchange for a covenant not to compete to be entered into
at or near the completion of the merger.

     Premark's directors and officers beneficially owned, as of September 30,
1999, approximately 4.41% of Premark's outstanding common stock, including
options. As of September 30, 1999, Illinois Tool Works' directors, officers and
their affiliates beneficially owned 2,196 shares of Premark common stock,
including options.

THE STOCK OPTION AGREEMENT

  General Description of the Stock Option Agreement

     At the same time the merger agreement was executed, Illinois Tool Works and
Premark entered into a stock option agreement under which Premark granted
Illinois Tool Works an option to purchase up to 12,203,694 shares of Premark
common stock, or such number of shares of Premark common stock as represents
19.9% of the then-outstanding shares of Premark common stock without giving
effect to the Premark common stock issued or issuable under the option, at a
price per share of $34.06. A copy of the form of the Stock Option Agreement is
included as Exhibit A to the merger agreement included in Annex A to this proxy
statement/prospectus.

                                       43
<PAGE>   50

  Exercise of the Option

     Except as described below, the option is exercisable within 135 days
following any event entitling Illinois Tool Works to receive the termination fee
under the merger agreement. The right to exercise the option expires upon
either:

     - the effective time of the merger; or

     - the earlier of:

          -- 135 days after the date that Illinois Tool Works becomes entitled
             to receive the termination fee under the merger agreement; and

          -- the date that Illinois Tool Works is no longer potentially entitled
             to receive the termination fee under the merger agreement for a
             reason other than that Illinois Tool Works has already received the
             termination fee.

  Adjustments to Number and Type of Shares

     The total number of shares of Premark common stock purchasable upon the
exercise of the option, and the option price, are subject to adjustment from
time to time to reflect changes in the capitalization of Premark.

  Cash Payment for the Option

     If the option becomes exercisable, Illinois Tool Works may require Premark
to repurchase the option in whole or in part, for a price equal to the number of
shares of Premark common stock then purchasable upon exercise of the option
multiplied by the excess of the "market/offer price" over the option price. The
market/offer price is defined in the stock option agreement as the highest of:

     - the price per share of Premark common stock at which a tender or exchange
       offer for Premark common stock has been made during the term of the
       option;

     - the price per share of Premark common stock to be paid by any other
       person pursuant to an agreement with Premark in connection with a
       business combination; and

     - the highest trading price for shares of Premark common stock on the New
       York Stock Exchange within the six-month period immediately preceding the
       delivery of the notice requesting cash payment for the option.

     If the option has been exercised, Illinois Tool Works may require Premark
to repurchase any shares of Premark common stock issued upon exercise of the
option at a price equal to the number of shares designated for repurchase
multiplied by the market/offer price.

  Repurchase at the Option of Premark

     After the option has been exercised, Premark has the right, exercisable
during the 135-day period beginning 135 days after the option becomes
exercisable, to repurchase three-quarters, but not less than three-quarters, of
the shares of Premark common stock acquired by Illinois Tool Works at a purchase
price per share equal to the greater of the market/offer price or the exercise
price of the option.

  First Refusal

     At any time prior to the second anniversary of the first purchase of
Premark shares under the option, Premark would have a right of first refusal
over the shares issued under the option in the event the holder desires to sell
or transfer such shares.

  Limitation on Profit

     The stock option agreement provides that in no event will Illinois Tool
Works' total profit from the option exceed in the aggregate $30 million.

                                       44
<PAGE>   51

  Registration Rights and Listing

     Premark will use its reasonable best efforts to (1) register any shares
purchased under the option under the securities laws for the sale or other
disposition by Illinois Tool Works of such shares and (2) cause the listing of
such shares on the New York Stock Exchange.

  Assignability

     The stock option agreement may not be assigned by Illinois Tool Works or
Premark without the prior written consent of the other.

  Effect of Stock Option Agreement

     The stock option agreement is expected to increase the likelihood that the
merger will be completed and to compensate Illinois Tool Works in certain
circumstances if the merger is not completed. Certain aspects of the stock
option agreement would have the effect of precluding any alternative business
combination from being accounted for as a "pooling-of-interests" and may
discourage persons who before the effective time of the merger might have been
interested in acquiring all of or a significant interest in Premark from
considering or proposing such an acquisition, even if such persons were prepared
to offer higher consideration per share for Premark common stock than that
offered by Illinois Tool Works.

                     MARKET PRICES AND DIVIDEND INFORMATION

     Shares of Illinois Tool Works common stock are traded on the New York Stock
Exchange and the Chicago Stock Exchange under the symbol "ITW," and shares of
Premark common stock are listed on the New York Stock Exchange and Pacific
Exchange under the symbol "PMI" and the London Stock Exchange under the symbol
"PMK." The following table sets forth, for the periods indicated, the range of
high and low per share sales prices for Illinois Tool Works common stock and
Premark common stock as reported on the New York Stock Exchange, as well as

            COMPARISON OF RIGHTS OF ILLINOIS TOOL WORKS STOCKHOLDERS
                            AND PREMARK STOCKHOLDERS

     The rights of Premark stockholders are currently governed by Delaware
corporate law and Premark's certificate of incorporation and bylaws. Upon
completion of the merger, Premark stockholders will become stockholders of
Illinois Tool Works and their rights as Illinois Tool Works stockholders will be
governed by Delaware corporate law and Illinois Tool Works' certificate of
incorporation and bylaws. There are a number of differences between the rights
of Illinois Tool Works stockholders and Premark stockholders. Set forth below is
a brief summary of the material differences between the rights of Illinois Tool
Works stockholders and the rights of Premark stockholders which is qualified in
its entirety by reference to the relevant provisions of Delaware corporate law,
Illinois Tool Works' certificate of incorporation and bylaws and Premark's
certificate of incorporation and bylaws. The charter documents are incorporated
by reference as exhibits to the registration statement of which this proxy
statement/prospectus is a part.

AUTHORIZED CAPITAL

  Illinois Tool Works

     Illinois Tool Works is authorized to issue 350,300,000 shares of all
classes of stock, 350,000,000 of which are shares of common stock and 300,000 of
which are shares of preferred stock. As of October 11, 1999, there were
250,674,938 shares of common stock issued and outstanding and no issued and
outstanding shares of preferred stock.

  Premark

     Premark is authorized to issue 250,000,000 shares of all classes of stock,
200,000,000 of which are shares of common stock and 50,000,000 of which are
shares of preferred stock. As of October 11, 1999, there were 61,427,603 shares
of common stock issued and outstanding and no issued and outstanding preferred
shares. As of October 11, 1999, 1,000,000 shares of preferred stock of Premark,
designated as Series A Junior Participating Preferred Stock, were reserved for
issuance pursuant to Premark's stockholder rights agreement described below.

STOCKHOLDER RIGHTS AGREEMENT

  Illinois Tool Works

     Illinois Tool Works does not have a stockholder rights agreement.

  Premark

     Premark has a stockholder rights agreement that could discourage unwanted
or hostile takeover attempts which are not approved by Premark's board of
directors. The rights agreement allows holders of Premark common stock to
purchase shares in either Premark or an acquiror at a discount to market value
in response to specified takeover events that are not approved in advance by
Premark's board of directors.

     The Rights. On December 16, 1996, Premark's board of directors declared a
dividend of one preferred share purchase right, referred to as a "right," for
each Premark common share outstanding. The rights currently trade with, and are
inseparable from, the common stock.

     Exercise Price. Each right allows its holder to purchase from Premark one
one-hundredth of a share of Premark Series A Junior Participating Preferred
Stock for $80. This portion of a preferred share will give the stockholder
approximately the same dividend, voting, and liquidation rights as would one
share of common stock.

     Exercisability. The rights will not be exercisable until:

     - 10 days after a public announcement that a person or group has obtained
       beneficial ownership of 15% or more of Premark's outstanding common
       stock; or

                                       46
<PAGE>   53

     - 10 business days after a person or group begins a tender or exchange
       offer which, if completed, would result in that person or group becoming
       the beneficial owner of 15% or more of Premark's outstanding common
       stock.

The date when the rights become exercisable is referred to in the rights
agreement as the "distribution date." After that date, the rights will be
evidenced by rights certificates that Premark will mail to all eligible holders
of common stock. A person or member of a group that has obtained beneficial
ownership of 15% or more of Premark's outstanding common stock may not exercise
any rights even after the distribution date.

  Consequences of a Person or Group Becoming an Acquiring Person.

     A person or group who acquires beneficial ownership of 15% or more of
Premark's shares is called an "acquiring person."

     - Flip In. If a person or group becomes an acquiring person, all holders of
       rights except the acquiring person may purchase shares of Premark common
       stock at half their market value.

     - Flip Over. If, after a person or group becomes an acquiring person,
       Premark merges or consolidates with another entity, or if 50% or more of
       Premark's consolidated assets or earning power are sold, all holders of
       rights except the acquiring person may purchase shares of the acquiring
       company at half their market value.

  The Amendment to the Rights Agreement.

     Immediately before entering into the merger agreement, Premark amended the
rights agreement to provide that the rights will not become exercisable as a
result of the merger agreement, the stock option agreement or the merger. The
rights agreement amendment also provides that neither Illinois Tool Works nor
Merger Sub will become an acquiring person as a result of the merger agreement,
the stock option agreement or the merger.

BOARD OF DIRECTORS

  Illinois Tool Works

     Illinois Tool Works' bylaws provide that the entire board of directors is
elected each year. A quorum of directors consists of a majority of Illinois Tool
Works' board of directors.

  Premark

     Premark's certificate of incorporation divides Premark's board of directors
into three classes of directors serving staggered three-year terms. As a result,
approximately one-third of Premark's board of directors is elected each year. A
quorum of directors consists of one-third of Premark's whole board of directors,
the "whole board" being defined as the number of directors the board would have
if there were no vacancies.

NUMBER, FILLING OF VACANCIES AND REMOVAL OF DIRECTORS

  Illinois Tool Works

     Illinois Tool Works' certificate of incorporation provides that its board
of directors may not have less than three nor more than 20 members. The actual
number of directors is as fixed in Illinois Tool Works' bylaws. Currently,
Illinois Tool Works has ten members on its board of directors. Any director or
the entire board of directors of Illinois Tool Works may be removed, with or
without cause, by majority stockholder vote.

                                       47
<PAGE>   54

  Premark

     Premark's certificate of incorporation and bylaws provide that its board of
directors may fix the number of directors by a vote of a majority of the whole
board. Currently, Premark's board of directors has nine members. Directors can
be removed only for cause by majority stockholder vote.

CONSTITUENCY PROVISION

  Illinois Tool Works

     Neither Illinois Tool Works' certificate of incorporation nor its bylaws
contains a provision authorizing the board of directors, in taking action, to
consider any interests other than the interests of stockholders.

  Premark

     Premark's certificate of incorporation provides that, in addition to any
other considerations Premark's board of directors may lawfully take into account
in determining whether to take or to refrain from taking corporate action on any
matter, the board of directors may consider the interests of creditors,
customers, employees and other constituencies of Premark and its subsidiaries,
as well as the effect that its decisions may have upon communities in which
Premark and its subsidiaries do business.

INDEMNIFICATION

     Illinois Tool Works' bylaws and Premark's certificate of incorporation
contain similar, but not identical, indemnification provisions. The material
differences between the indemnification provisions are as follows:

  Persons Covered

     Illinois Tool Works' indemnification provisions cover all Illinois Tool
Works' directors, officers, employees and agents and all those who have served
at its request as a director, officer, employee or agent of another entity.

     Premark's indemnification provisions cover all Premark's directors,
officers and employees, all those who have served at its request as a director,
officer, employee or agent of another entity, and the legal representatives of
all those persons.

  Expenses Covered

     The expenses expressly covered under Illinois Tool Works' indemnification
provisions include attorneys' fees, judgments, fines and amounts paid in
settlement.

     The expenses expressly covered under Premark's indemnification provisions
include all those just mentioned plus ERISA excise taxes and penalties.

  Role of Covered Party

     Illinois Tool Works will indemnify a covered person who was or is a party,
or is threatened to be made a party to any threatened, pending or completed
action, suit or nonderivative proceeding.

     Premark will indemnify a covered person in all the circumstances just
mentioned, and also when the covered person is involved in any action, suit or
proceeding, whether derivative or not derivative, as a party or as a non-party.

  Limitations

     In the case of a derivative action, Illinois Tool Works will not indemnify
a covered person who has been adjudged to be liable for negligence or misconduct
in the performance of his or her duties, unless a

                                       48
<PAGE>   55

court determines that the covered person is entitled to indemnification
notwithstanding his or her negligence or misconduct. Premark's certificate of
incorporation contains no similar provision.

  Advances

     Illinois Tool Works may advance to a covered party expenses incurred in
defending a civil or criminal action, suit or proceeding if the covered party
undertakes to repay the amount advanced unless he or she is ultimately found
eligible for indemnification.

     Premark will advance to a covered party any indemnifiable expense. If the
covered party is a director or officer, he or she must undertake to repay the
amount advanced if ultimately found ineligible for indemnification.

  Suit for Indemnification

     If Premark does not pay in full the indemnification amount due within 30
days of receiving notice of a claim for indemnification, the claimant may sue
Premark to recover the unpaid amount, as well as the expenses incurred in
prosecuting such claim. Illinois Tool Works' bylaws contain no similar
provision.

SPECIAL MEETINGS OF STOCKHOLDERS

  Illinois Tool Works

     Illinois Tool Works' certificate of incorporation provides that only the
chairman, the president or a majority of the board of directors may call a
special meeting of stockholders.

  Premark

     Premark's certificate of incorporation provides that only a majority of the
whole board of directors may call a special meeting of stockholders.

ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER PROPOSALS OTHER THAN ELECTION OF
DIRECTORS

  Illinois Tool Works

     Neither Illinois Tool Works' certificate of incorporation nor its bylaws
contain provisions relating to stockholder proposals other than with respect to
the election of directors.

  Premark

     Premark's bylaws provide that a stockholder may propose that business be
brought before an annual stockholders' meeting if notice of such proposal is
delivered to and received at the principal executive office of Premark not more
than 120 days nor less than 90 days prior to the anniversary date of the prior
year's annual meeting. If the date of the meeting has changed more than 30 days
from the prior year, then the stockholder's notice must be received not later
than the 10th day following the date the meeting was publicly announced.

ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS OF DIRECTORS AT AN ANNUAL
MEETING

  Illinois Tool Works

     Illinois Tool Works' bylaws provide that a stockholder may nominate a
person for election to the board of directors at an annual stockholders' meeting
if the stockholder gives notice not later than the last business day of December
prior to the annual meeting in April or May.

  Premark

     Premark's bylaws provide that a stockholder may nominate a person for
election to the board of directors at an annual meeting of the stockholders if
the nomination is received not more than 120 days

                                       49
<PAGE>   56

nor less than 90 days prior to the anniversary date of the prior year's annual
meeting. If the date of the meeting has changed more than 30 days from the prior
year, then the nomination must be received not later than the close of business
on the 10th day following the date the meeting was publicly announced.

ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS OF DIRECTORS AT A SPECIAL
MEETING

  Illinois Tool Works

     Illinois Tool Works' bylaws provide that a stockholder may nominate a
person for election to the board of directors at a special meeting of
stockholders at which directors are to be elected if the stockholder gives
Illinois Tool Works' corporate secretary notice of the nomination not later than
the close of business on the tenth day following the date on which notice of the
special meeting is first given to stockholders.

  Premark

     Premark's bylaws provide that the only business that may be conducted at
any special meeting is business which is brought before the meeting by or at the
direction of the board of directors.

BUSINESS COMBINATION TRANSACTIONS

     Illinois Tool Works' certificate of incorporation contains a provision that
requires, in specified circumstances, supermajority stockholder approval of
business combination transactions with significant stockholders. Premark's
certificate of incorporation contains a similar provision. The material
differences between the provisions are as follows:

  Definition of Significant Stockholder

     Illinois Tool Works' certificate of incorporation applies generally to
those who beneficially own more than 10% of the outstanding Illinois Tool Works
common stock, excluding any stock acquired on or before March 2, 1984.

     Premark's certificate of incorporation applies generally to those who
beneficially own 10% or more of the outstanding Premark common stock or those
who are affiliated or associated with Premark and who beneficially owned 10% or
more of the outstanding Premark common stock within the previous two years.

  Business Combination Transactions Covered

     Illinois Tool Works' certificate of incorporation contains a definition of
"business combination" that includes

     - mergers or consolidations with a substantial stockholder;

     - dispositions of more than one percent of the total gross assets of
       Illinois Tool Works to a substantial stockholder;

     - acquisitions of assets with a value of more than one percent of the total
       gross assets of Illinois Tool Works from a substantial stockholder;

     - issuances or transfers of Illinois Tool Works securities by Illinois Tool
       Works to a substantial stockholder; and

     - issuances or transfers of securities of a substantial stockholder by the
       substantial stockholder to Illinois Tool Works.

     The definition of "business combination" in Premark's certificate of
incorporation is similar to the Illinois Tool Works definition. However,
Premark's certificate of incorporation does not include within the definition an
acquisition of assets of a substantial stockholder by Premark, nor does it
include an issuance or transfer of securities of a substantial stockholder by
the substantial stockholder to Premark.

                                       50
<PAGE>   57

Furthermore, under the Premark definition, dispositions of assets to substantial
stockholders and transfers of securities of Premark to substantial stockholders
are "business combinations" if the assets or securities transferred have an
aggregate fair market value of $10 million or more.

  Vote Required

     Illinois Tool Works' certificate of incorporation provides that any
business combination transaction must be approved by a two-thirds majority
stockholder vote and a majority vote of the stockholders other than the
substantial stockholder.

     Premark's certificate of incorporation provides that any business
combination transaction must be approved by an 80% majority stockholder vote.

  Exempted Transactions

     Illinois Tool Works' certificate of incorporation exempts a transaction
from the supermajority vote requirement if it

     - has been approved by at least two-thirds of Illinois Tool Works'
       continuing directors;

     - was approved by a majority of Illinois Tool Works' board of directors
       before the substantial stockholder became a substantial stockholder;

     - involves only Illinois Tool Works and a corporation of which Illinois
       Tool Works owns more than 50% of the outstanding voting stock; or

     - satisfies specified fair price criteria and procedural requirements.

     Premark's certificate of incorporation exempts a transaction from the
supermajority vote requirement if it

     - has been approved by a majority of Premark's continuing directors, and
       there are at least five such directors; or

     - satisfies fair price criteria and procedural requirements similar to
       those specified in the Illinois Tool Works certificate of incorporation.

     Premark's board of directors has taken all necessary actions to render the
business combination provisions of its certificate of incorporation inapplicable
to the merger, the merger agreement and the stock option agreement.

AMENDMENTS TO CERTIFICATE OF INCORPORATION AND BYLAWS

  Illinois Tool Works

     Illinois Tool Works' certificate of incorporation requires a two-thirds
majority stockholder vote to:

     - repeal or amend the provisions of the certificate of incorporation
       related to (1) the number of members of the board of directors and the
       filling of vacancies thereof, (2) stockholders' meetings and the
       prohibition of stockholder action by written consent, (3) the approval of
       certain business combinations with substantial stockholders, and (4)
       amendments to the certificate of incorporation and bylaws; or

     - amend the certificate of incorporation to provide for cumulative voting.

     If there is a substantial stockholder, any repeal, amendment or adoption of
the type discussed above must also be approved by a majority vote of
stockholders other than the substantial stockholder.

     Illinois Tool Works' certificate of incorporation provides that new bylaws
may be adopted, or the bylaws may be amended or repealed, either by the vote of
a majority of the board of directors or by a

                                       51
<PAGE>   58

majority stockholder vote, except that any bylaw fixing the number of directors
may be adopted, amended or repealed only by (1) the vote of a majority of the
directors, unless there exists a substantial stockholder in which case such
bylaw must also be adopted, amended or repealed by not less than two-thirds of
the continuing directors or (2) a two-thirds majority stockholder vote, unless
there exists a substantial stockholder in which case such bylaw must also be
adopted, amended or repealed by a majority vote of stockholders other than the
substantial stockholder.

  Premark

     Premark's certificate of incorporation requires an 80% majority stockholder
vote to alter, amend or repeal any provision of the certificate of incorporation
related to:

     - the number, election and removal of the members of the board of directors
       and the filling of vacancies on the board of directors;

     - the approval of business combination transactions with substantial
       stockholders;

     - stockholders' meetings and the prohibition of stockholder action by
       written consent; or

     - amendments to the bylaws.

     Premark's bylaws provide that the vote of a majority of directors, or an
80% majority stockholder vote is required to amend, add to, rescind or repeal
Premark's bylaws.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

     The following unaudited pro forma combined financial statements ("Pro Forma
Statements") give effect to the proposed merger of Illinois Tool Works and
Premark under the "pooling-of-interests" method of accounting. The Pro Forma
Statements are based on the historical financial statements of the respective
companies and should be read in conjunction with those historical financial
statements and related notes thereto, which are incorporated by reference in

Inc. ("Illinois Tool Works") and Premark International, Inc. ("Premark") as
accounted for by the "pooling-of-interests" method. In accordance with
Securities and Exchange Commission reporting rules, the pro forma combined
statements of income, and the historical statements from which they are derived,
present only income from continuing operations and therefore do not include
discontinued operations, extraordinary items or the cumulative effects of
accounting changes. The pro forma combined statements of income also do not
include the impact of nonrecurring items attributable to the transaction.

     Because the transaction has not been completed, the costs of the merger
transaction can only be estimated at this time. The pro forma combined statement
of income for each period presented excludes: (1) the positive effects of
potential cost savings that may be achieved upon combining the resources of the
companies; (2) transaction costs including investment banking, legal, and
accounting fees; and (3) contractual termination benefits.

     The unaudited pro forma combined statement of financial position as of June
30, 1999 includes, in accordance with the Securities and Exchange Commission
reporting rules, the impact of all transactions, whether of a recurring or
nonrecurring nature, that can be reasonably estimated and that would have been
reflected had the transaction been consummated as of that date.

2. PRO FORMA ADJUSTMENTS

     As permitted in a pooling-of-interests business combination, the unaudited
pro forma financial statements reflect certain adjustments to conform the
accounting policies and financial statement classification of both companies.
The pro forma adjustments are as follows:

  Statement of Financial Position

     (a)Illinois Tool Works and Premark have classified other intangible assets
        differently in their respective statements of financial position. Other
        intangible assets of $172.4 million were classified in the Illinois Tool
        Works historical financial statements as other assets, and were
        reclassified in the pro forma statement of financial position to
        goodwill and other intangible assets in order to conform the
        presentation.

     (b)Upon the original adoption of Statement of Financial Accounting
        Standards No. 106 -- Employers' Accounting for Postretirement Benefits
        other than Pensions ("SFAS 106") there were two options to recognize the
        transition obligation. Illinois Tool Works chose to recognize the
        transition obligation over a 20-year period. Premark chose the option of
        immediate recognition. The combined entity will follow the immediate
        recognition method. The pro forma combined statement of financial
        position reflects an adjustment to other noncurrent liabilities of $99.0
        million to record Illinois Tool Works' unamortized transition obligation
        as of June 30, 1999. Noncurrent deferred taxes have been adjusted by
        $38.6 million to account for the tax effect of the unamortized
        transition obligation.

     (c)Illinois Tool Works and Premark have classified dividends payable
        differently in their respective statements of financial position.
        Dividends payable of $6.7 million were classified in the Premark
        historical financial statements as accrued expenses, and were
        reclassified in the pro forma statement of financial position to cash
        dividends payable in order to conform the presentation.

     (d)A pro forma adjustment of $20 million was recorded to accrued expenses
        and income reinvested in the business in order to reflect the estimated
        transaction costs related to the merger.

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     (e)Accrued expenses and income reinvested in the business have been
        adjusted to reflect $43.8 million in payments related to contractual
        termination benefits that are expected to be paid subsequent to the
        consummation of the merger transaction. Income taxes payable has been
        adjusted by $8.5 million to reflect the tax effect relating to the
        termination payments.

     (f)Common stock ($.01 par value per share) was adjusted by $68.6 million to
        reflect the merger accounted for as a "pooling-of-interests" through the
        exchange of approximately 43.1 million shares of Illinois Tool Works
        common stock for 61.2 million shares of Premark common stock using an
        illustrative exchange ratio of 0.7049. The exchange ratio is based on a
        market value of $55 worth of Illinois Tool Works' stock issued to
        Premark stockholders upon consummation of the merger transaction, and an
        average market value of Illinois Tool Works' stock of $78.03 for the
        20-day period ending September 9, 1999. As described in this proxy
        statement/prospectus, the actual exchange ratio will be based on the
        average closing price of Illinois Tool Works common stock for the 20-day
        trading period ending on the second business day before the effective
        time of the merger.

     (g)Treasury stock was adjusted by $258.3 million to reflect the retirement
        of Premark's treasury stock.

     (h)Additional paid-in-capital was adjusted by $189.7 million related to
        adjustments (f) and (g) above.

     (i)Illinois Tool Works and Premark have classified the cumulative
        translation adjustment differently in their respective statements of
        financial position. Translation adjustments were classified in the
        Premark historical financial statements as accumulated other
        comprehensive income, and were reclassified in the pro forma statement
        of financial position as cumulative translation adjustment in order to
        conform the presentation.

     (j)Included in Premark's historical statement of financial position is the
        unearned portion of restricted stock issued for future service, which
        was adjusted by $2.5 million to reflect the vesting of the restricted
        shares upon consummation of the merger transaction.

     (k)Income reinvested in the business was adjusted by $118.2 million related
        to adjustments (b), (d), (e) and (j) above, as follows (in thousands,
        net of tax):

     (l)Illinois Tool Works and Premark have classified long-term deferred tax
        assets differently in their respective statements of financial position.
        Long-term deferred tax assets of $33.6 million were classified in the
        Premark historical financial statements as other noncurrent assets, and
        were reclassified to deferred income taxes in the pro forma statement of
        financial position in order to conform the presentation.

     (m)Illinois Tool Works and Premark have used different methods for
        depreciating fixed assets in their historical financial statements.
        Illinois Tool Works has principally used accelerated depreciation
        methods (primarily in its U.S. businesses), whereas Premark historically
        has used the straight-line depreciation method. Because the merger
        transaction has not been completed, the adjustment to conform Premark's
        depreciation method to that of Illinois Tool Works is not currently
        estimable. Upon consummation of the transaction, the depreciation method
        for

        Premark's U.S. businesses is expected to be conformed to Illinois Tool
        Works' accelerated methods in the financial statements for all periods.

 Statements of Income

     (n)Illinois Tool Works and Premark have classified distribution costs
        differently in their respective statements of income. Distribution costs
        were classified in the Premark historical financial statements as
        selling and administrative expenses, and were reclassified in the pro
        forma statements of income as cost of revenues in order to conform the
        presentation.

     (o)Illinois Tool Works and Premark have classified goodwill and other
        intangible asset amortization differently in their respective statements
        of income. Amortization was classified in the Premark historical
        financial statements as a selling and administrative expense, and was
        reclassified in the pro forma statements of income as amortization of
        goodwill and intangible assets in order to conform the presentation.

     (p)Upon the original adoption of SFAS 106, there were two options to
        recognize the transition obligation. Illinois Tool Works chose to
        recognize the transition obligation as of January 1, 1993 ratably over a
        20-year period. Premark chose the option of immediate recognition. The
        combined entity will follow the immediate recognition method. The pro
        forma combined statements of income reflect the elimination of Illinois
        Tool Works' amortization of retiree health care.

     (q)The estimated income tax effect related to the pro forma adjustments
        described in (p) above is based on an assumed combined federal and state
        income tax rate of 39%.

     (r)The pro forma combined per share amounts are based on the combined
        weighted average number of Illinois Tool Works common shares and Premark
        common stock outstanding for all periods presented assuming Premark
        stockholders receive 0.7049 of an Illinois Tool Works common share for
        each share of Premark common stock held.

     4.1. Effect on Capital Stock. At the Effective Time, the Merger shall have
the following effects on the capital stock of the Company and Merger Sub,
without any action on the part of the holder of any capital stock of the Company
or Merger Sub:

          (a) Merger Consideration. Each share of common stock, $1.00 par value
     per share, of the Company (each a "Company Share" and collectively the
     "Company Shares") issued and outstanding immediately prior to the Effective
     Time (but not including Company Shares that are owned by Parent, Merger Sub
     or any other direct or indirect subsidiary of Parent (collectively, the
     "Parent Companies") or Company Shares that are owned by the Company or any
     direct or indirect subsidiary of the Company, and in each case not held on
     behalf of third parties (collectively, "Excluded Company Shares")), shall
     be converted into and become exchangeable for the fraction of a share (the
     "Exchange Ratio" or the "Merger Consideration") of Common Stock, $0.01 par
     value per share, of Parent ("Parent Common Stock"), equal to:

             (i) if the Parent Average Price is equal to or greater than $66.33
        but less than or equal to $89.73, the result, calculated to four decimal
        places, of $55.00 divided by the Parent Average Price;

             (ii) if the Parent Average Price is greater than $89.73 but less
        than $101.44, the result, calculated to four decimal places, of

             [$55.00 + {.3065 (Parent Average Price - $89.73)}] / Parent Average
        Price;

                                       A-7
<PAGE>   80

             (iii) if the Parent Average Price is less than $66.33 but greater
        than $54.62, the result, calculated to four decimal places, of

             [$55.00 - {.4146 ($66.33 - Parent Average Price)}] / Parent Average
        Price;

             (iv) if the Parent Average Price is greater than or equal to
        $101.44, .5776;

             (v) if the Parent Average Price is less than or equal to $54.62,
        .9181.

The "Parent Average Price" means the average of the closing price per share of
Parent Common Stock on the New York Stock Exchange (the "NYSE"), as reported in
The Wall Street Journal, New York City edition, on the twenty NYSE trading days
ending on the second business day prior to the Closing Date. The Parent Average
Price shall be rounded to the nearest cent.

     At the Effective Time, all Company Shares shall no longer be outstanding,
shall be canceled and retired and shall cease to exist, and each certificate (a
"Certificate") formerly representing any of such Company Shares (other than
Excluded Company Shares) shall thereafter represent only the right to the Merger
Consideration in respect of each Company Share formerly represented by such
Certificate multiplied by the number of Company Shares formerly represented by
such Certificate and the right, if any, to receive pursuant to Section 4.2(d)
cash in lieu of the fractional shares into which such Company Shares have been
converted pursuant to this Section 4.1(a) and any distribution or dividend
pursuant to Section 4.2(b), in each case without interest.

          (b) Cancellation of Excluded Company Shares. Each Excluded Company
     Share issued and outstanding immediately prior to the Effective Time shall,
     by virtue of the Merger and without any action on the part of the holder
     thereof, no longer be outstanding, shall be canceled and retired without
     payment of any consideration therefor and shall cease to exist.

          (c) Merger Sub. At the Effective Time, each share of Common Stock, par
     value $0.01 per share, of Merger Sub issued and outstanding immediately
     prior to the Effective Time shall be converted into one share of common
     stock of the Surviving Corporation, and the Surviving Corporation shall
     thereby become a wholly owned subsidiary of Parent.

     4.2. Exchange of Certificates for Shares.

          (a) Exchange Procedures. At or prior to the Effective Time Parent
     shall deposit with the Exchange Agent (as defined below), in trust for the
     benefit of the holders of Company Shares, certificates representing shares
     of Parent Common Stock issuable pursuant to Section 4.1(a), and an amount
     of cash sufficient to pay cash in lieu of fractional shares in accordance
     with Section 4.2(d). Parent shall make sufficient funds available to the
     Exchange Agent from time to time as needed to pay cash in respect of
     dividends or other distributions in accordance with Section 4.2(b).
     Promptly after the Effective Time, but in no event later than three
     business days following the Closing Date, the Surviving Corporation shall
     cause an exchange agent (the "Exchange Agent"), selected by Parent with the
     Company's prior approval, which shall not be unreasonably withheld, to mail
     to each holder of record as of the Effective Time of a Certificate in
     respect of Company Shares (other than holders of a Certificate in respect
     of Excluded Company Shares) (i) a letter of transmittal specifying that
     delivery of the Certificates shall be effected, and that risk of loss and
     title to the Certificates shall pass, only upon delivery of the
     Certificates (or affidavits of loss and indemnity undertakings or indemnity
     bonds, as the case may be, in lieu thereof) to the Exchange Agent, such
     letter of transmittal to be in such form and have such other provisions as
     Parent and the Company may reasonably agree, and (ii) instructions for
     exchanging the Certificates for (A) certificates representing shares of
     Parent Common Stock and (B) any cash in lieu of fractional shares
     determined in accordance with Section 4.2(d) plus any cash dividends and
     any other dividends or other distributions that such holder has the right
     to receive pursuant to the provisions of this Article IV. Subject to
     Section 4.2(g), upon surrender of a Certificate for cancellation to the
     Exchange Agent together with such letter of transmittal, duly executed, the
     holder of such Certificate shall be entitled to receive in exchange
     therefor (x) a certificate representing that number of whole shares of
     Parent Common Stock that such holder is entitled to receive pursuant to
     this Section 4.2, and (y) a check in the

                                       A-8
<PAGE>   81

     amount (after giving effect to any required tax withholdings) of (A) any
     cash in lieu of fractional shares determined in accordance with Section
     4.2(d) plus (B) any cash dividends and any other dividends or other
     distributions that such holder has the right to receive pursuant to the
     provisions of this Section 4.2. The Certificate so surrendered shall
     forthwith be canceled. No interest will be paid or accrued on any amount
     payable upon due surrender of any Certificate. In the event of a transfer
     of ownership of Company Shares that occurred prior to the Effective Time,
     but is not registered in the transfer records of the Company, a certificate
     representing the proper number of shares of Parent Common Stock, together
     with a check for any cash in lieu of fractional shares to be paid upon due
     surrender of the Certificate and any other dividends or distributions in
     respect thereof, may be issued and/or paid to such a transferee if the
     Certificate formerly representing such Company Shares is presented to the
     Exchange Agent, accompanied by all documents required to evidence and
     effect such transfer and to evidence that any applicable stock transfer
     taxes have been paid. If any certificate for shares of Parent Common Stock
     is to be 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 Person requesting such exchange shall pay any
     transfer or other taxes required by reason of the issuance of certificates
     for 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 Parent or the Exchange Agent that such tax has been paid or
     is not applicable.

          (b) Distributions with Respect to Unexchanged Shares; Voting.

             (i) Whenever a dividend or other distribution is declared by Parent
        in respect of Parent Common Stock, the record date for which is at or
        after the Effective Time, that declaration shall include dividends or
        other distributions in respect of all shares of Parent Common Stock
        issuable pursuant to this Agreement. No dividends or other distributions
        so declared in respect of such Parent Common Stock shall be paid to any
        holder of any unsurrendered Certificate until such Certificate is
        surrendered for exchange in accordance with this Section 4.2. Subject to
        the effect of applicable laws, following surrender of any such
        Certificate, there shall be issued or paid to the holder of the
        certificates representing whole shares of Parent Common Stock issued in
        exchange for such Certificate, without interest, (A) at the time of such
        surrender, the dividends or other distributions with a record date that
        is at or after the Effective Time and a payment date on or prior to the
        date of issuance of such whole shares of Parent Common Stock and not
        previously paid and (B) at the appropriate payment date, the dividends
        or other distributions payable with respect to such whole shares of
        Parent Common Stock with a record date at or after the Effective Time
        but with a payment date subsequent to surrender. For purposes of
        dividends or other distributions in respect of shares of Parent Common
        Stock, all shares of Parent Common Stock to be issued pursuant to the
        Merger shall be deemed issued and outstanding as of the Effective Time.

             (ii) Registered holders of unsurrendered Certificates shall be
        entitled to vote after the Effective Time at any meeting of Parent
        stockholders with a record date at or after the Effective Time the
        number of whole shares of Parent Common Stock represented by such
        Certificates, regardless of whether such holders have exchanged their
        Certificates.

          (c) Transfers. After the Effective Time, there shall be no transfers
     on the stock transfer books of the Company of the Company Shares that were
     outstanding immediately prior to the Effective Time.

          (d) Fractional Shares. Notwithstanding any other provision of this
     Agreement, no fractional shares of Parent Common Stock will be issued and
     any holder of Company Shares entitled to receive a fractional share of
     Parent Common Stock but for this Section 4.2(d) shall be entitled to
     receive in lieu thereof an amount in cash (without interest) determined by
     multiplying such fraction (rounded to the nearest one-hundredth of a share)
     by the average closing price of a share of Parent Common Stock, as reported
     in The Wall Street Journal, New York City edition, on the five (5) trading
     days immediately prior to the Effective Time.

                                       A-9
<PAGE>   82

          (e) Termination of Exchange Period; Unclaimed Stock. Any shares of
     Parent Common Stock and any portion of the cash, dividends or other
     distributions with respect to the Parent Common Stock deposited by Parent
     with the Exchange Agent (including the proceeds of any investments thereof)
     that remain unclaimed by the stockholders of the Company 180 days after the
     Effective Time shall be paid to Parent. Any stockholders of the Company who
     have not theretofore complied with this Article IV shall thereafter be
     entitled to look only to Parent for payment of their shares of Parent
     Common Stock and any cash, dividends and other distributions in respect
     thereof issuable and/or payable pursuant to Section 4.1, Section 4.2(b) and
     Section 4.2(d) upon due surrender of their Certificates (or, in lieu of
     such Certificates, affidavits of loss together with either a reasonable
     undertaking to indemnify Parent or the Company, if Parent believes that the
     person providing the indemnity is sufficiently creditworthy, or, if Parent
     does not so believe, indemnity bonds), in each case, without any interest
     thereon. Notwithstanding the foregoing, none of Parent, the Surviving
     Corporation, the Exchange Agent or any other Person shall be liable to any
     former holder of Company Shares for any amount properly delivered to a
     public official pursuant to applicable abandoned property, escheat or
     similar laws.

          (f) Lost, Stolen or Destroyed Certificates. In the event 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 Parent believes that the person providing
     the indemnity is sufficiently creditworthy, the making of a reasonable
     undertaking to indemnify Parent or the Company, or, if Parent does not so
     believe, the posting by such Person of a bond in the form customarily
     required by Parent to indemnify against any claim that may be made against
     it with respect to such Certificate, Parent will issue the shares of Parent
     Common Stock and the Exchange Agent will distribute such stock, any cash,
     dividends and other distributions in respect thereof issuable or payable in
     exchange for such lost, stolen or destroyed Certificate pursuant to Section
     4.1, Section 4.2(b) and Section 4.2(d), in each case, without interest.

          (g) Affiliates. Notwithstanding anything in this Agreement to the
     contrary, Certificates surrendered for exchange by any Pooling Affiliate or
     Rule 145 Affiliate (as determined pursuant to Section 6.7) of the Company
     shall not be exchanged until Parent has received a written agreement from
     such Person as provided in Section 6.7.

     4.3. Dissenters' Rights. The parties hereto agree that, in accordance with
Section 262 of the DGCL, no appraisal rights will be available to holders of
Company Shares in connection with the Merger.

     4.4. Adjustments to Prevent Dilution. In the event that prior to the
Effective Time, there shall have been declared or effected a reclassification,
stock split (including a reverse split), or stock dividend or stock distribution
made with respect to the Company Shares or the Parent Common Stock, or a stock
dividend or stock distribution or any similar transaction relating to the
Company Shares or the Parent Common Stock, the Exchange Ratio shall be equitably
adjusted to reflect such event.

                                   ARTICLE V.

                         REPRESENTATIONS AND WARRANTIES

     5.1. Representations and Warranties of the Company. Except as set forth in
the disclosure letter, dated the date of this Agreement, delivered by the
Company to Parent (the "Company Disclosure Letter") or in the Company's Reports
(as defined below) filed after December 31, 1996 but prior to the date of this
Agreement, the Company represents and warrants to Parent and Merger Sub that:

          (a) Organization, Good Standing and Qualification. Each of the Company
     and its Subsidiaries is a corporation duly organized, validly existing and
     in good standing under the laws of its respective jurisdiction of
     organization and has all requisite corporate or similar power and authority
     to own and operate its properties and assets and to carry on its business
     as presently conducted and is qualified to do business and is in good
     standing as a foreign corporation in each jurisdiction where the ownership

                                      A-10
<PAGE>   83

     or operation of its properties or conduct of its business requires such
     qualification, except where the failure to have such power and authority or
     to be so qualified or in good standing is not, when taken together with all
     other such failures, reasonably likely to have a Material Adverse Effect
     (as defined below) on it. The Company has made available to Parent a
     complete and correct copy of its certificate of incorporation and bylaws,
     each as amended to date. Such certificate of incorporation and bylaws are
     in full force and effect.

          (b) Capital Structure. The authorized capital stock of the Company
     consists of 200,000,000 Company Shares, of which 61,325,093 Company Shares
     were issued and outstanding and 7,678,747 Company Shares were held in
     treasury as of the close of business on September 7, 1999, and 50,000,000
     shares of Preferred Stock, $1.00 par value per share (the "Company
     Preferred Shares"), none of which was outstanding as of the date hereof.
     All of the outstanding Company Shares have been duly authorized and are
     validly issued, fully paid and nonassessable. Other than the 1,000,000
     Company Preferred Shares designated as Series A Junior Participating
     Preferred Stock that are reserved for issuance pursuant to the Rights
     Agreement, dated as of November 6, 1996, by and between the Company and
     Norwest Bank Minnesota, N.A., as Rights Agent (the "Rights Agreement"), and
     Company Shares subject to issuance as set forth below or that are permitted
     to become subject to issuance pursuant to Section 6.1(a)(iv) or (vii) of
     this Agreement, the Company has no Company Shares, Company Preferred Shares
     or other shares of capital stock reserved for or otherwise subject to
     issuance. As of the date of this Agreement, the Company has outstanding
     $150,000,000 aggregate principal amount of 6.875% notes due 2008,
     $100,000,000 aggregate principal amount of 10.5% notes due 2000 and
     $2,600,000 aggregate principal amount of 5.95% industrial revenue bonds due
     2002. As of September 7, 1999, there were 7,069,414 Company Shares that the
     Company was obligated to issue pursuant to the Company's stock plans at a
     weighted average exercise price of $18.20 per Company Share, each of which
     plans is listed in Section 5.1(b) of the Company Disclosure Letter
     (collectively the "Company Stock Plans"). Each of the outstanding shares of
     capital stock or other securities of each of the Company's Significant
     Subsidiaries is duly authorized, validly issued, fully paid and
     nonassessable and owned by the Company or a direct or indirect wholly owned
     Subsidiary of the Company, free and clear of any lien, pledge, security
     interest, claim or other encumbrance, except for such failures or
     exceptions to the foregoing as are not reasonably likely to have a Material
     Adverse Effect on the Company. Except as set forth above and except
     pursuant to the Stock Option Agreement, there are no preemptive or other
     outstanding rights, options, warrants, conversion rights, stock
     appreciation rights, redemption rights, repurchase rights, agreements,
     arrangements or commitments granted by or enforceable against the Company
     or any of its Significant Subsidiaries to issue or sell any shares of
     capital stock, other securities of the Company or any of its Subsidiaries
     or a material amount of assets of the Company or any of its Significant
     Subsidiaries other than (in the case of assets) in the ordinary course of
     business or any securities or obligations convertible or exchangeable into
     or exercisable for, or giving any Person a right to subscribe for or
     acquire, any shares of capital stock, other securities or material amount
     of assets of the Company or any of its Significant Subsidiaries, and no
     securities or obligations evidencing such rights are issued or outstanding.
     Neither the Company nor any of its Subsidiaries has outstanding any bonds,
     debentures, notes or other debt obligations the holders of which have the
     right to vote with the stockholders of the Company on any matter or
     convertible into or exercisable for securities having the right to vote
     with the stockholders of the Company on any matter. The Company Shares
     issuable pursuant to the Stock Option Agreement have been duly reserved for
     issuance by the Company, and upon any issuance of such Company Shares in
     accordance with the terms of the Stock Option Agreement, such Company
     Shares will be duly and validly issued and fully paid and nonassessable. No
     Company Shares are held by a Subsidiary of the Company.

          (c) Corporate Authority; Approval and Fairness. The Company has all
     requisite corporate power and authority and has taken all corporate action
     necessary in order to execute, deliver and perform its obligations under
     this Agreement and the Stock Option Agreement and, subject only to adoption
     of this Agreement by the holders of at least a majority of the outstanding
     Company Shares (the "Company Requisite Vote") to consummate the Merger.
     This Agreement has been duly
                                      A-11
<PAGE>   84

     executed and delivered by the Company and is a valid and binding agreement
     of the Company enforceable against the Company in accordance with its
     terms, subject to bankruptcy, insolvency, fraudulent transfer,
     reorganization, moratorium and similar laws of general applicability
     relating to or affecting creditors' rights and to general equity principles
     (the "Bankruptcy and Equity Exception"). The Stock Option Agreement has
     been duly executed and delivered by the Company and is a valid and binding
     agreement of the Company enforceable against the Company in accordance with
     its terms, subject to the Bankruptcy and Equity Exception. The Board of
     Directors of the Company (A) has approved and declared advisable this
     Agreement, the Stock Option Agreement and the Merger and (B) has received
     the opinion of its financial advisors, Goldman, Sachs & Co., to the effect
     that the Merger Consideration to be received by the holders of the Company
     Shares in the Merger is fair to such holders from a financial point of
     view.

          (d) Governmental Filings; No Violations.

             (i) Other than the filings and/or notices (A) pursuant to Section
        1.3, (B) under the HSR Act, the Exchange Act and the Securities Act, (C)
        pursuant to the European Community Merger Control Regulation, (D) to
        comply with state securities or "blue-sky" laws and (E) to comply with
        any other relevant Competition Laws (as defined below), no notices,
        reports or other filings are required to be made by the Company with,
        nor are any consents, registrations, approvals, permits or
        authorizations required to be obtained by the Company from, any
        governmental or regulatory authority, court, agency, commission, body or
        other governmental entity ("Governmental Entity"), in connection with
        the execution and delivery of this Agreement and the Stock Option
        Agreement by the Company and the consummation by the Company of the
        Merger and the other transactions contemplated by this Agreement and the
        Stock Option Agreement, except those the failure to make or obtain,
        individually or in the aggregate, are not reasonably likely to have a
        Material Adverse Effect on the Company and those that to the knowledge
        of the Company's executive officers, as of the date hereof, would not be
        reasonably likely to prevent, materially delay or materially impair the
        Company's ability to consummate the transactions contemplated by this
        Agreement or the Stock Option Agreement.

             (ii) The execution, delivery and performance of this Agreement and
        the Stock Option Agreement by the Company do not, and the consummation
        by the Company of the Merger and the other transactions contemplated by
        this Agreement and the Stock Option Agreement will not, constitute or
        result in (A) a breach or violation of, or a default under, the
        Company's certificate of incorporation or bylaws or the comparable
        governing instruments of any of the Company's Significant Investees or
        (B) a breach or violation of, a default under, or give rise to a right
        of termination under, the acceleration of any obligations or the
        creation of a lien, pledge, security interest or other encumbrance on
        its assets or the assets of any of the Company's Significant Investees
        (with or without notice, lapse of time or both) pursuant to, any
        agreement, license, lease, contract, note, mortgage, indenture,
        arrangement or other obligation ("Contracts") binding upon the Company
        or any of its Significant Investees or any Law (as defined in Section
        5.1(i)) or governmental or non-governmental permit or license to which
        the Company or any of its Significant Investees are subject or (C) any
        change in the rights or obligations of any party under any Contracts to
        which the Company or its Significant Investees are a party, except, in
        the case of clauses (B) or (C) above, for any breach, violation,
        default, right of termination, acceleration, creation or change that,
        individually or in the aggregate, is not reasonably likely to have a
        Material Adverse Effect on the Company and that to the knowledge of the
        Company's executive officers, as of the date hereof, would not be
        reasonably likely to prevent, materially delay or materially impair the
        Company's ability to consummate the transactions contemplated by this
        Agreement or the Stock Option Agreement.

          (e) Reports; Financial Statements. The Company has filed with the SEC
     all required forms, reports, registration statements and documents required
     to be filed by it with the SEC since December 31, 1996. The Company has
     made or will make available to Parent each registration statement, report,
     proxy statement or information statement prepared by the Company since
                                      A-12
<PAGE>   85

     December 31, 1996, including the Company's Annual Report on Form 10-K for
     the years ended December 28, 1996, December 27, 1997 and December 26, 1998
     and the Company's Quarterly Report on Form 10-Q for the quarters ended
     March 27, 1999 and June 26, 1999 in the form (including exhibits, annexes
     and any amendments thereto) filed with the SEC (collectively, including any
     such reports filed subsequent to the date of this Agreement, the "Company's
     Reports"). As of their respective dates, the Company's Reports complied as
     to form in all material respects with all applicable requirements under the
     Securities Act, the Exchange Act and the rules and regulations thereunder
     and did not contain any untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements made therein, in light of the circumstances in which they
     were made, not misleading. Each of the consolidated balance sheets included
     in or incorporated by reference into the Company's Reports (including the
     related notes and schedules) fairly presents the consolidated financial
     position of the Company and its consolidated Subsidiaries as of its date
     and each of the consolidated statements of income, stockholders' equity and
     of cash flows included in or incorporated by reference into the Company's
     Reports (including any related notes and schedules) fairly presents the
     consolidated results of operations, retained earnings and cash flows, as
     the case may be, of the Company and its consolidated Subsidiaries for the
     periods set forth therein (subject, in the case of unaudited statements, to
     the absence of notes (to the extent permitted by the rules applicable to
     Form 10-Q) and to normal year-end audit adjustments that will not be
     material in amount or effect), in each case in accordance with GAAP
     consistently applied during the periods involved, except as may be noted
     therein. Except as set forth in Section 5.1(e) of the Company Disclosure
     Letter or except as may be reflected in any public filing made prior to the
     date of this Agreement with the SEC under Section 13 of the Exchange Act
     and the regulations promulgated thereunder, to the Company's knowledge, as
     of the date of this Agreement, no Person or "group" "beneficially owns" 5%
     or more of the Company's outstanding voting securities, with the terms
     "beneficially owns" and "group" having the meanings ascribed to them under
     Rule 13d-3 and Rule 13d-5 under the Exchange Act.

          (f) Absence of Certain Changes. Except as disclosed in the Company's
     Reports filed prior to the date of this Agreement or as expressly
     contemplated by this Agreement, since December 26, 1998 (the "Audit Date"),
     the Company and its Subsidiaries have conducted their respective businesses
     only in the ordinary and usual course of such businesses and there has not
     been: (i) any change in the financial condition, liabilities and assets
     (taken together) or business of the Company and its Subsidiaries which,
     individually or in the aggregate, is reasonably likely to have a Material
     Adverse Effect on the Company; (ii) any damage, destruction or other
     casualty loss with respect to any asset or property owned, leased or
     otherwise used by the Company or any of its Subsidiaries, whether or not
     covered by insurance, which damage, destruction or loss is reasonably
     likely, individually or in the aggregate, to have a Material Adverse Effect
     on the Company; (iii) any declaration, setting aside or payment of any
     dividend or other distribution in respect of the Company's capital stock
     other than regular quarterly cash dividends not in excess of $.11 per
     Common Share; or (iv) any material change by the Company in financial
     accounting principles, practices or methods, except as required by GAAP.
     Since the Audit Date, except as provided for in this Agreement, in the
     Company Disclosure Letter or as disclosed in the Company's Reports filed
     prior to the date of this Agreement and except for increases and amendments
     that are not material in the aggregate, there has not been any increase in
     the salary, wage, bonus, grants, awards, benefits or other compensation
     payable or that could become payable by the Company or any of its
     Subsidiaries to directors, officers or key employees or any amendment of
     any of the Company's Compensation and Benefit Plans (as defined in Section
     5.1(h)(i)) other than increases or amendments in the normal and usual
     course of the Company's business (which may include normal periodic
     performance reviews and related compensation and benefit increases and the
     provision of new individual compensation and benefits for promoted or newly
     hired officers and employees on terms consistent with past practice).

          (g) Litigation and Liabilities. Except as disclosed in the Company's
     Reports filed prior to the date of this Agreement, there are no (i) civil,
     criminal or administrative actions, suits, claims,

                                      A-13
<PAGE>   86

     hearings, investigations or proceedings pending or, to the actual knowledge
     of the Company's executive officers, threatened against the Company or any
     of its Affiliates or (ii) obligations or liabilities of the Company or any
     of its Subsidiaries, whether or not accrued, contingent or otherwise and
     whether or not required to be disclosed, including those relating to
     matters involving any Environmental Law, in either such case, except for
     those that, individually or in the aggregate, are not reasonably likely to
     have a Material Adverse Effect on the Company and that to the knowledge of
     the Company's executive officers, as of the date hereof, would not be
     reasonably likely to prevent, materially delay or materially impair the
     Company's ability to consummate the transactions contemplated by this
     Agreement or the Stock Option Agreement.

          (h) Employee Benefits.

             (i) The term "Compensation and Benefit Plans" means any employee
        benefit plan (within the meaning of Section 3(3) of ERISA), or any
        bonus, deferred compensation, pension, retirement, profit-sharing,
        thrift, savings, incentive compensation, employee stock ownership, stock
        bonus, stock purchase, restricted stock, stock option, employment,
        consulting, termination, severance, compensation, medical, health or
        fringe benefit plan, program, agreement, policy or arrangement for any
        agents, consultants, employees, directors, former employees or former
        directors of the Company and/or any ERISA Affiliate which the Company or
        any ERISA Affiliate maintains, is a party to, participates in or with
        respect to which any of them has any liability or contingent liability.
        The Company has delivered to Parent copies of certain plan documents and
        summary plan descriptions for certain Compensation and Benefit Plans,
        and such copies are, to the knowledge of the Company's executive
        officers, true and complete in all material respects.

             (ii) (A) All Compensation and Benefit Plans have been administered
        in form and operation in substantial compliance with all requirements of
        applicable law, and no event has occurred which will or could cause any
        such Compensation and Benefit Plan to fail to comply with such
        requirements and no notice has been issued by any governmental authority
        questioning or challenging such compliance; (B) there have been no acts
        or omissions by the Company or any ERISA Affiliate which have given rise
        to or may give rise to material fines, penalties, taxes or related
        charges under Section 502 of ERISA or Chapters 43, 47, 68 or 100 of the
        Code for which the Company or ERISA Affiliate may be liable; (C) each of
        the Compensation and Benefit Plans that is an "employee pension benefit
        plan" within the meaning of Section 3(2) of ERISA, other than a
        multiemployer plan (as defined in Section 3(37) of ERISA) (each a
        "Pension Plan"), and that is intended to be qualified under Section
        401(a) of the Code has received a favorable determination letter from
        the IRS or an application therefor filed within the applicable remedial
        amendment period is pending which covers all changes in law for which
        the remedial amendment period (within the meaning of Section 401(b) of
        the Code and applicable regulations) has expired and none of the Company
        nor any of its ERISA Affiliates is aware of any circumstances likely to
        result in revocation of any such favorable determination letter; (D)
        there is no pending or, to the knowledge of the Company's executive
        officers, threatened material litigation relating to its Compensation
        and Benefit Plans; and (E) neither the Company nor any of the ERISA
        Affiliates has engaged in a transaction with respect to any of the
        Compensation and Benefit Plans that would subject the Company or any of
        the ERISA Affiliates to a material tax or penalty imposed by either
        Section 4975 of the Code or Section 502 of ERISA.

             (iii) All contributions required to be made under the terms of any
        of the Compensation and Benefit Plans as of the date of this Agreement
        have been timely made or have been reflected on the most recent
        consolidated balance sheet filed or incorporated by reference in the
        Company's Reports prior to the date of this Agreement.

             (iv) None of the Company nor any ERISA Affiliate has any obligation
        for post-employment health and life benefits under any of the
        Compensation and Benefit Plans, except as set forth in its Reports filed
        prior to the date of this Agreement or as required by applicable law

                                      A-14
<PAGE>   87

        or as may be provided under individual employment or severance
        agreements which in the aggregate do not require the Company to provide
        benefits, the cost of which is material to the Company.

             (v) The consummation of the Merger (or the approval of the Merger
        by stockholders of the Company) and the other transactions contemplated
        by this Agreement does not (x) entitle any employees or directors of the
        Company or any employees of any of the Company's ERISA Affiliates to
        severance pay, directly or indirectly, upon termination of employment or
        otherwise, (y) accelerate the time of payment or vesting or trigger any
        payment of compensation or benefits under, increase the amount payable
        or trigger any other material obligation pursuant to, any of the
        Compensation and Benefit Plans or (z) result in any breach or violation
        of, or a default under, any of the Compensation and Benefit Plans.

             (vi) In each summary plan description and plan document relating to
        a Compensation and Benefits Plan that is not an individual agreement,
        the Company has reserved the right unilaterally to amend or terminate
        such plan, and to the knowledge of the Company's executive officers as
        of the date hereof, the Company has not distributed any other documents
        to participants generally or issued any general communication that
        purports to promise that any such plan will be continued indefinitely or
        otherwise obligates the Company to provide a specific level of benefits
        in the future, except under the terms of a collective bargaining
        agreement, a change-in-control provision that has been disclosed to
        Parent prior to the date of this Agreement or an individual agreement
        that has been disclosed to Parent prior to the date of this Agreement,
        or except as may be required by a statutory provision requiring the
        continuation of certain benefits or requiring that certain steps be
        taken, such as notification to affected participants, before a plan
        amendment or termination can be effective.

             (vii) None of the Compensation and Benefit Plans is a
        "multiemployer plan", within the meaning of Section 4001(a)(3) of ERISA
        that is subject to Title IV of ERISA (a "Multi-employer Plan"), none of
        the Compensation and Benefit Plans is otherwise subject to Title IV of
        ERISA and none of the Company or any of the ERISA Affiliates have
        contributed or been obligated to contribute to a Multiemployer Plan or
        any other plan which is subject to Title IV of ERISA.

          (i) Compliance with Laws. Except as set forth in the Company's Reports
     filed prior to the date of this Agreement, the businesses of each of the
     Company and its Subsidiaries have not been, and are not being, conducted in
     violation of any Laws except for violations or possible violations that,
     individually or in the aggregate, are reasonably likely to have a Material
     Adverse Effect on the Company or that to the knowledge of the Company's
     executive officers, as of the date hereof, would be reasonably likely to
     prevent, materially delay or materially impair the Company's ability to
     consummate the transactions contemplated by this Agreement and the Stock
     Option Agreement. Except as set forth in the Company's Reports filed prior
     to the date of this Agreement, to the actual knowledge of the Company's
     executive officers, no investigation or review by any Governmental Entity
     with respect to the Company or any of its Subsidiaries is pending or
     threatened, nor has any Governmental Entity indicated an intention to
     conduct the same, which, individually or in the aggregate, are reasonably
     likely to have a Material Adverse Effect on the Company or to the knowledge
     of the Company's executive officers, as of the date hereof, would be
     reasonably likely to prevent, materially delay or materially impair the
     Company's ability to consummate the transactions contemplated by this
     Agreement and the Stock Option Agreement. To the actual knowledge of the
     Company's executive officers, no material change is required in the
     Company's or any of its Subsidiaries' processes, properties or procedures
     in order to comply with any such Laws, and the Company has not received any
     written notice or written communication of any material noncompliance with
     any such Laws that has not been cured as of the date of this Agreement,
     except for changes and noncompliance that individually or in the aggregate,
     are not reasonably likely to have a Material Adverse Effect on the Company
     and that to the knowledge of the Company's executive

                                      A-15
<PAGE>   88

     officers, as of the date hereof, would not be reasonably likely to prevent,
     materially delay or materially impair the Company's ability to consummate
     the transactions contemplated by this Agreement and the Stock Option
     Agreement. Each of the Company and its Subsidiaries has all Permits
     necessary to conduct their business as presently conducted, except for
     those the absence of which, individually or in the aggregate, are not
     reasonably likely to have a Material Adverse Effect on the Company and that
     to the knowledge of the Company's executive officers, as of the date
     hereof, would not be reasonably likely to prevent, materially delay or
     materially impair the Company's ability to consummate the transactions
     contemplated by this Agreement and the Stock Option Agreement.

          (j) Takeover Statutes; Charter and Bylaw Provisions. The Board of
     Directors of the Company has taken all appropriate and necessary actions to
     render inapplicable to the Merger and the transactions contemplated by this
     Agreement the provisions of Section 203 of the DGCL. No other "fair price,"
     "moratorium," "control share acquisition" or other similar anti-takeover
     statute or regulation of any state in the United States (each a "Takeover
     Statute") as in effect on the date of this Agreement is applicable to the
     Company, the Company Shares, the Merger or the other transactions
     contemplated by this Agreement or the Stock Option Agreement. Assuming that
     Parent and its Affiliates were not, at or prior to the date of this
     Agreement (without giving effect to the Stock Option Agreement),
     "Interested Stockholders" within the meaning of Article EIGHTH, Section
     B(2)(vii)(2) of the Company's certificate of incorporation, the Company's
     Board of Directors has taken such action as is necessary to render Article
     EIGHTH, Section A of the Company's certificate of incorporation
     inapplicable to the Merger or the other transactions contemplated by this
     Agreement or the Stock Option Agreement. Article NINTH of the Company's
     certificate of incorporation has expired in accordance with its terms.

          (k) Environmental Matters. Except as disclosed or reflected in the
     Company's Reports filed prior to the date of this Agreement and except for
     such matters that, alone or in the aggregate, are not reasonably likely to
     have a Material Adverse Effect on the Company: (i) each of the Company and
     its Subsidiaries has complied with all applicable Environmental Laws; (ii)
     neither the Company nor any of its Subsidiaries has received any notice,
     demand, letter, claim or request for information alleging that the Company
     or any of its Subsidiaries may be in violation of or liable under any
     Environmental Law; (iii) neither the Company nor any of its Subsidiaries is
     subject to any orders, decrees, injunctions or other arrangements with any
     Governmental Entity or is subject to any indemnity or other agreement with
     any third party relating to liability under any Environmental Law or
     relating to Hazardous Substances; and (iv) there are no circumstances or
     conditions involving the Company or any of its Subsidiaries that could
     reasonably be expected to result in any claims, liability, investigations,
     costs or restrictions on the ownership, use, or transfer of any of the
     Company's properties pursuant to any Environmental Law.

          (l) Accounting and Tax Matters. Neither the Company nor any of its
     Subsidiaries or Pooling Affiliates (as defined in Section 6.7) has taken or
     agreed to take any action, nor do the Company's executive officers have any
     actual knowledge of any fact or circumstance, that would prevent Parent
     from accounting for the business combination to be effected by the Merger
     as a "pooling-of-interests" in accordance with the Pooling Requirements or
     prevent the Merger from qualifying as a "reorganization" within the meaning
     of Section 368(a) of the Code.

          (m) Taxes. Except to the extent of any inaccuracy or incompleteness of
     any of the following which is not, individually or in the aggregate,
     reasonably likely to have a Material Adverse Effect on the Company, (i) the
     Company and each of its Subsidiaries have prepared or will prepare in good
     faith and duly and timely filed (taking into account any extension of time
     within which to file), or will so file, all material Tax Returns required
     to be filed by any of them at or before the Effective Time and all such
     filed Tax Returns are or will be complete and accurate, (ii) the Company
     and each of its Subsidiaries as of the Effective Time (x) will have paid
     all Taxes that they are required to pay prior to the Effective Time, and
     (y) will have withheld all federal, state and local income taxes, FICA,
     FUTA and other Taxes, including, without limitation, similar foreign Taxes,
     required to be withheld from amounts owing to any employee, creditor or
     third party, (iii) as of the date of this
                                      A-16
<PAGE>   89

     Agreement, there are not pending or threatened in writing, any audits,
     examinations, investigations or other proceedings in respect of Taxes or
     Tax matters, (iv) there are not, to the actual knowledge of the Company's
     executive officers, any unresolved questions, claims or outstanding
     proposed or assessed deficiencies concerning the Company or any of its
     Subsidiaries' Tax liability, (v) neither the Company nor any of its
     Subsidiaries has any liability with respect to income, franchise or similar
     Taxes in excess of the amounts accrued in respect of such Taxes that are
     reflected in the financial statements included in the Company's Reports and
     (vi) neither the Company nor any of its Subsidiaries has executed any
     waiver of any statute of limitations on, or extended the period for the
     assessment or collection of, any Tax. No payments to be made to any of the
     officers and employees of the Company or its Subsidiaries will, as a result
     of consummation of the Merger, be subject to the deduction limitations
     under Sections 280G or 162(m) of the Code.

          (n) Labor Matters. Neither the Company nor any of its Subsidiaries is
     the subject of any material proceeding asserting that the Company or any of
     its Subsidiaries has committed an unfair labor practice or is seeking to
     compel the Company to bargain with any labor union or labor organization
     nor is there pending or, to the knowledge of the Company's executive
     officers, threatened, any labor strike, dispute, walkout, work stoppage,
     slow down or lockout involving the Company or any of its Subsidiaries,
     except in each case as is not, individually or in the aggregate, reasonably
     likely to have a Material Adverse Effect on the Company.

          (o) Brokers and Finders; Professional Expenses. Neither the Company
     nor any of its officers, directors or employees has employed any broker or
     finder or incurred any liability for any brokerage fees, commissions or
     finders' fees in connection with the Merger or the other transactions
     contemplated by this Agreement except that the Company has employed
     Goldman, Sachs & Co. as the Company's financial advisor. The calculation of
     the amount payable to Goldman, Sachs & Co. in connection with this
     Agreement, including the Merger and the other transactions contemplated by
     this Agreement, is disclosed in Section 5.1(o) of the Company Disclosure
     Letter and true and complete copies of all engagement letters and other
     Contracts relating to currently active assignments under which Goldman,
     Sachs & Co. may be entitled to any engagement, assignment, fees, expense
     reimbursement, indemnification or other payment from the Company or any of
     its Subsidiaries are attached to the Company Disclosure Letter.

          (p) Significant Agreements. Each of the Significant Agreements is in
     full force and effect and enforceable in accordance with its terms, except
     as would not reasonably be expected to have a Material Adverse Effect on
     the Company. Neither the Company nor any of its Subsidiaries has received
     any notice (written or oral) of cancellation or termination of, or any
     expression or indication of an intention or desire to cancel or terminate,
     any of the Significant Agreements, except as would not reasonably be
     expected to have a Material Adverse Effect on the Company. No Significant
     Agreement is the subject of, or has been threatened to be made the subject
     of, any arbitration, suit or other legal proceeding, except as would not
     reasonably be expected to have a Material Adverse Effect on the Company.
     With respect to any Significant Agreement which by its terms will terminate
     as of a certain date unless renewed or unless an option to extend such
     Significant Agreement is exercised, neither the Company nor any of its
     Subsidiaries has received any notice (written or oral), or otherwise has
     any knowledge, that any such Significant Agreement will not be, or is not
     likely to be, so renewed or that any such extension option will not be
     exercised, except as would not reasonably be expected to have a Material
     Adverse Effect on the Company. There exists no event of default or
     occurrence, condition or act on the part of the Company or any of its
     Subsidiaries or, to the knowledge of the Company, on the part of the other
     parties to the Significant Agreements which constitutes or would constitute
     (with notice or lapse of time or both) a breach of or default under any of
     the Significant Agreements, except as would not reasonably be expected to
     have a Material Adverse Effect on the Company. Neither the Company nor any
     of its Subsidiaries is a party to or otherwise bound by any Contract
     purporting to limit the Company or any of its Affiliates from engaging in
     any business or from competing with any Person in any business, except as
     would not reasonably be expected to have a Material Adverse Effect on the
     Company. Neither the Company nor

                                      A-17
<PAGE>   90

     any of its Subsidiaries is a party to or otherwise bound by any Contract
     purporting to limit any direct or indirect shareholder or parent company of
     the Company (or any Subsidiary of any direct or indirect shareholder or
     parent company of the Company, other than the Company or any Subsidiary of
     the Company) from engaging in any business or from competing with any
     Person in any business except as would not have a Material Adverse Effect
     on Parent.

          (q) Intellectual Property Rights. Except as would not have a Material
     Adverse Effect on the Company:

             (i) The Company and its Subsidiaries own or have the right to use
        all intellectual property material to the conduct of their respective
        businesses (such intellectual property and such rights are collectively
        referred to herein as the "Company IP Rights").

             (ii) The execution, delivery and performance of this Agreement by
        the Company and the consummation by the Company of the transactions
        contemplated hereby will not (A) constitute a breach by the Company or
        any of its Subsidiaries of any instrument or agreement governing any
        Company IP Rights, (B) cause the modification of any terms of any
        licenses or agreements relating to any Company IP Rights including but
        not limited to the modification of the effective rate of any royalties
        or other payments provided for in any such license or agreement, (C)
        cause the forfeiture or termination of any Company IP Rights, (D) give
        rise to a right of forfeiture or termination of any Company IP Rights or
        (E) impair the right of the Company, its Subsidiaries, the Surviving
        Corporation or Parent to use, sell or license any Company IP Rights or
        portion thereof.

             (iii) Neither the manufacture, marketing, license, sale or intended
        use of any product or product under development (collectively,
        "Products") by the Company and its Subsidiaries nor the current use by
        the Company and its Subsidiaries of any Company IP Rights, (A) violates
        any license or agreement between the Company or any of its Subsidiaries
        and any third party or (B) infringes any patents or other intellectual
        property rights of any other party; and there is no pending or
        threatened claim or litigation contesting the validity, ownership or
        right to use, sell, license or dispose of any Company IP Rights, or
        asserting that any Company IP Rights or the proposed use, sale, license
        or disposition thereof, or the manufacture, use or sale of any Products,
        conflicts or will conflict with the rights of any other party.

          (r) Year 2000 Compliance. The Company has instituted processes and
     controls to become Year 2000 Compliant, as that term is defined below, and
     the foreseeable expenses or other liabilities associated with the process
     of securing full Year 2000 Compliance would not be reasonably expected to
     cause a Material Adverse Effect on the Company. Upon completion of such
     instituted processes and controls the Company's Computer Systems will be
     Year 2000 Compliant. "Year 2000 Compliant" means, except for any
     noncompliance that, individually or in the aggregate would not be
     reasonably likely to have a Material Adverse Effect on the Company, that
     such hardware or software used, by the Company or any of its Subsidiaries
     including, but not limited to, microcode, firmware, system and application
     programs, files, databases, computer services, and microcontrollers,
     including those embedded in computer and non-computer equipment (the
     "Computer Systems") will not fail (because of a date change event resulting
     from a transition to the Year 2000) to:

             (i) process date data consistently from before and after January 1,
        2000;

             (ii) maintain functionality with respect to the introduction,
        processing, or output of records containing dates falling on or after
        January 1, 2000; and

             (iii) be interoperable with other Year 2000 Compliant software or
        hardware which may deliver records to, receive records from, or interact
        with such Computer Systems in the course of conducting the business of
        the Company, including processing data and manufacturing the products of
        the Company.

          (s) Rights Agreement. The Company has adopted an amendment to the
     Rights Agreement with the effect that neither Parent nor Merger Sub shall
     be deemed to be an Acquiring Person (as defined in the Rights Agreement),
     the Distribution Date (as defined in the Rights Agreement) shall not be
     deemed to occur and the Rights (as defined in the Rights Agreement) will
     not separate from the Company Shares, as a result of entering into this
     Agreement or the Stock Option Agreement or consummating the Merger and/or
     the other transactions contemplated by this Agreement or the Stock Option
     Agreement.

     5.2. Representations and Warranties of Parent and Merger Sub. Except as set
forth in the disclosure letter, dated the date of this Agreement, delivered by
Parent to the Company (the "Parent Disclosure Letter") or in Parent's Reports
filed after December 31, 1996 but prior to the date of this Agreement, Parent,
on behalf of itself and Merger Sub, represents and warrants to the Company that:

          (a) Organization, Good Standing and Qualification. Each of Parent and
     its Subsidiaries is a corporation duly organized, validly existing and in
     good standing under the laws of its respective jurisdiction of organization
     and has all requisite corporate or similar power and authority to own and
     operate its properties and assets and to carry on its business as presently
     conducted and is qualified to do business and is in good standing as a
     foreign corporation in each jurisdiction where the ownership or operation
     of its properties or conduct of its business requires such qualification,
     except where the failure to have such power and authority or to be so
     qualified or in good standing is not, when taken together with all other
     such failures, reasonably likely to have a Material Adverse Effect on it.
     Parent has made available to Company a complete and correct copy of its
     certificate of incorporation and bylaws, each as amended to date. Such
     certificates of incorporation and bylaws are in full force and effect.

          (b) Capital Structure.

             (i) The authorized capital stock of Parent consists of 350,000,000
        shares of Parent Common Stock, of which 250,637,386 shares were issued
        and outstanding and 260,536 shares were held in treasury as of the close
        of business on September 7, 1999, and 300,000 shares of Preferred Stock,
        no par value (the "Parent Preferred Shares"), of which no shares were
        outstanding as of the date hereof. All of the outstanding shares of
        Parent Common Stock have been duly authorized and are validly issued,
        fully paid and nonassessable. As of the date of this Agreement, other
        than Parent Common Stock subject to issuance as set forth below, Parent
        has no shares of Parent Common Stock or Parent Preferred Shares reserved
        for or subject to issuance. As of September 7, 1999, there were not more
        than 5,344,999 shares of Parent Common Stock that Parent was obligated
        to issue pursuant to the Parent's stock plans, each of which plans is
        listed in Section 5.2(b) of the Parent Disclosure Letter (collectively,
        the "Parent Stock Plans"). Except as set forth above, as of the date of
        this Agreement, there are no preemptive or other outstanding rights,
        options, warrants, conversion rights, stock appreciation rights,
        redemption rights, repurchase rights, agreements, arrangements or
        commitments to issue or to sell any shares of capital stock or other
        securities of Parent or any securities or obligations convertible or
        exchangeable into or exercisable for, or giving any Person a right to
        subscribe for or acquire, any securities of Parent, and no securities or
        obligation evidencing such rights are authorized, issued or outstanding.
        As of the date of this Agreement, Parent does not have outstanding any
        bonds, debentures, notes or other debt 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.

             (ii) The authorized capital stock of Merger Sub consists of 1,000
        shares of Common Stock, par value $0.01 per share, all of which are
        validly issued and outstanding. All of the issued and outstanding
        capital stock of Merger Sub is, and at the Effective Time will be, owned
        by Parent, and there are (A) no other shares of capital stock or other
        voting securities of Merger Sub, (B) no securities of Merger Sub
        convertible into or exchangeable for shares of capital stock or other
        voting securities of Merger Sub and (C) no options or other rights to
        acquire from Merger

                                      A-19
<PAGE>   92

        Sub, and no obligations of Merger Sub to issue, any capital stock, other
        voting securities or securities convertible into or exchangeable for
        capital stock or other voting securities of Merger Sub. Merger Sub has
        not conducted any business prior to the date of this Agreement and has
        no, and prior to the Effective Time will have no, assets, liabilities or
        obligations of any nature other than those incident to its formation and
        pursuant to this Agreement and the Merger and the other transactions
        contemplated by this Agreement.

          (c) Corporate Authority; Approval. Parent and Merger Sub each has all
     requisite corporate power and authority and each has taken all corporate
     action necessary in order to execute, deliver and perform its obligations
     under this Agreement and to consummate the Merger. This Agreement has been
     duly executed and delivered by Parent and Merger Sub and is a valid and
     binding agreement of Parent and Merger Sub, enforceable against each of
     Parent and Merger Sub in accordance with its terms, subject to the
     Bankruptcy and Equity Exception. The shares of Parent Common Stock, when
     issued pursuant to this Agreement, will be validly issued, fully paid and
     nonassessable, and no stockholder of Parent will have any preemptive right
     of subscription or purchase in respect thereof.

          (d) Governmental Filings; No Violations.

             (i) Other than the filings and/or notices (A) pursuant to Section
        1.3, (B) under the HSR Act, the Exchange Act and the Securities Act, (C)
        pursuant to the European Community Merger Control Regulation, (D) to
        comply with state securities or "blue-sky" laws and (E) to comply with
        any other relevant Competition Laws, no notices, reports or other
        filings are required to be made by Parent with, nor are any consents,
        registrations, approvals, permits or authorizations required to be
        obtained by Parent from, any Governmental Entity, in connection with the
        execution and delivery of this Agreement and the Stock Option Agreement
        by Parent and the consummation by Parent of the Merger and the other
        transactions contemplated by this Agreement and the Stock Option
        Agreement, except those that the failure to make or obtain, individually
        or in the aggregate, are not reasonably likely to have a Material
        Adverse Effect on Parent and that to the knowledge of Parent's executive
        officers, as of the date hereof, would not be reasonably likely to
        prevent, materially delay or materially impair Parent's ability to
        consummate the transactions contemplated by this Agreement or the Stock
        Option Agreement.

             (ii) The execution, delivery and performance of this Agreement and
        the Stock Option Agreement by Parent do not, and the consummation by
        Parent of the Merger and the other transactions contemplated by this
        Agreement and the Stock Option Agreement will not, constitute or result
        in (A) a breach or violation of, or a default under, Parent's
        certificate of incorporation or bylaws or the comparable governing
        instruments of any of Parent or its Significant Subsidiaries or any
        Significant Investees or (B) subject to the approval of the issuance of
        the aggregate Merger Consideration by a majority of the stockholders of
        Parent voting thereon at the Parent Stockholders Meeting (as defined in
        Section 6.4(b) (the "Parent Requisite Vote"), if applicable, a breach or
        violation of, a default under or give rise to a right of termination
        under, the acceleration of any obligations or the creation of a lien,
        pledge, security interest or other encumbrance on its assets or the
        assets of any of Parent or its Significant Investees (with or without
        notice, lapse of time or both) pursuant to, any Contracts binding upon
        Parent or any of its Significant Investees or any Law or governmental or
        non-governmental permit or license to which Parent or any of its
        Significant Investees is subject or (C) any change in the rights or
        obligations of any party under any Contracts to which Parent or its
        Significant Investees are a party, except, in the case of clauses (B) or
        (C) above, for any breach, violation, default, acceleration, creation or
        change that, individually or in the aggregate, is not reasonably likely
        to have a Material Adverse Effect on Parent and that to the knowledge of
        Parent's executive officers, as of the date hereof, would not be
        reasonably likely to prevent, materially delay or materially impair
        Parent's ability to consummate the transactions contemplated by this
        Agreement or the Stock Option Agreement.

                                      A-20
<PAGE>   93

          (e) Reports; Financial Statements. Parent has made or will make
     available to the Company each registration statement, report, proxy
     statement or information statement prepared by Parent since December 31,
     1996, including Parent's Annual Report on Form 10-K for the years ended
     December 31, 1996, December 31, 1997 and December 31, 1998 and Parent's
     Quarterly Report on Form 10-Q for the quarters ended March 31, 1999 and
     June 30, 1999 in the form (including exhibits, annexes and any amendments
     thereto) filed with the SEC (collectively, including any such reports filed
     subsequent to the date of this Agreement, "Parent's Reports"). As of their
     respective dates, Parent's Reports complied as to form in all material
     respects with all applicable requirements under the Securities Act, the
     Exchange Act and the rules and regulations thereunder and did not contain
     any untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements made
     therein, in light of the circumstances in which they were made, not
     misleading. Each of the consolidated balance sheets included in or
     incorporated by reference into Parent's Reports (including the related
     notes and schedules) fairly presents the consolidated financial position of
     Parent and its consolidated Subsidiaries as of its date and each of the
     consolidated statements of income, stockholders' equity and cash flows
     included in or incorporated by reference into Parent's Reports (including
     any related notes and schedules) fairly presents the consolidated results
     of operations, statement of shareholders' investment and cash flows, as the
     case may be, of Parent and its consolidated Subsidiaries for the periods
     set forth therein (subject, in the case of unaudited statements, to the
     absence of notes (to the extent permitted by the rules applicable to Form
     10-Q) and to normal year-end audit adjustments that will not be material in
     amount or effect), in each case in accordance with GAAP consistently
     applied during the periods involved, except as may be noted therein.

          (f) Absence of Certain Changes. Except as disclosed in the Parent's
     Reports filed prior to the date of this Agreement or as expressly
     contemplated by this Agreement, since December 31, 1998, there has not
     been: (i) any change in the financial condition, liabilities and assets
     (taken together) or business of Parent and its Subsidiaries which,
     individually or in the aggregate, is reasonably likely to have a Material
     Adverse Effect on Parent; or (ii) any declaration, setting aside or payment
     of any dividend or other distribution in respect of Parent's capital stock
     other than regular quarterly cash dividends consistent with past practice
     and other than any dividend that would be received by the holders of
     Company Common Stock on an equivalent basis per share of Parent Common
     Stock after the Effective Time.

          (g) Accounting and Tax Matters. Neither Parent nor any of its
     Subsidiaries or Pooling Affiliates (as defined in Section 6.7) has taken or
     agreed to take any action, nor do Parent's executive officers have any
     actual knowledge of any fact or circumstance, that would prevent Parent
     from accounting for the business combination to be effected by the Merger
     as a "pooling-of-interests" in accordance with the Pooling Requirements or
     prevent the Merger from qualifying as a "reorganization" within the meaning
     of Section 368(a) of the Code. Neither Parent nor any of its Subsidiaries
     owns any shares of capital stock of the Company or any other securities
     convertible into or otherwise exercisable to acquire capital stock of the
     Company other than any securities that may be held pursuant to any pension
     or benefit plan of Parent or any of its Subsidiaries.

          (h) Compliance with Laws. Except as set forth in Parent's Reports
     filed prior to the date of this Agreement, the businesses of each of Parent
     and its Subsidiaries have not been, and are not being, conducted in
     violation of any Laws except for violations or possible violations that,
     individually or in the aggregate, are not reasonably likely to have a
     Material Adverse Effect on Parent and that to the knowledge of Parent's
     executive officers, as of the date hereof, would not prevent, materially
     delay or materially impair Parent's ability to consummate the transactions
     contemplated by this Agreement and the Stock Option Agreement. Except as
     set forth in Parent's Reports filed prior to the date of this Agreement, to
     the actual knowledge of Parent's executive officers, no investigation or
     review by any Governmental Entity with respect to Parent or any of its
     Subsidiaries is pending or threatened, nor has any Governmental Entity
     indicated an intention to conduct the same, which, individually or in the
     aggregate, are reasonably likely to have a Material Adverse Effect on
     Parent or that to the

                                      A-21
<PAGE>   94

     knowledge of Parent's executive officers, as of the date hereof, would be
     reasonably likely to prevent, materially delay or materially impair
     Parent's ability to consummate the transactions contemplated by this
     Agreement and the Stock Option Agreement. To the actual knowledge of
     Parent's executive officers, no material change is required in Parent's or
     any of its Subsidiaries' processes, properties or procedures in order to
     comply with any such Laws, and Parent has not received any written notice
     or written communication of any material noncompliance with any such Laws
     that has not been cured as of the date of this Agreement, except for
     changes and noncompliance that, individually or in the aggregate, are not
     reasonably likely to have a Material Adverse Effect on Parent and that to
     the knowledge of Parent's executive officers, as of the date hereof, would
     not prevent, materially delay or materially impair Parent's ability to
     consummate the transactions contemplated by this Agreement and the Stock
     Option Agreement. Each of Parent and its Subsidiaries has all Permits
     necessary to conduct their business as presently conducted, except for
     those the absence of which, individually or in the aggregate, are not
     reasonably likely to have a Material Adverse Effect on Parent and that to
     the knowledge of Parent's executive officers, as of the date hereof, would
     not prevent, materially delay or materially impair Parent's ability to
     consummate the transactions contemplated by this Agreement and the Stock
     Option Agreement.

          (i) Litigation and Liabilities. Except as disclosed in Parent's
     Reports filed prior to the date of this Agreement, there are no (i) civil,
     criminal or administrative actions, suits, claims, hearings, investigations
     or proceedings pending or, to the actual knowledge of Parent's executive
     officers, threatened against Parent or any of its Affiliates or (ii)
     obligations or liabilities of Parent or any of its Subsidiaries, whether or
     not accrued, contingent or otherwise and whether or not required to be
     disclosed, including those relating to matters involving any Environmental
     Law, in either such case, except for those that, individually or in the
     aggregate, are not reasonably likely to have a Material Adverse Effect on
     Parent and that to the knowledge of Parent's executive officers, as of the
     date hereof, would not prevent, materially delay or materially impair
     Parent's ability to consummate the transactions contemplated by this
     Agreement or the Stock Option Agreement.

          (j) Environmental Matters. Except as disclosed or reflected in
     Parent's Reports filed prior to the date of this Agreement and except for
     such matters that, alone or in the aggregate, are not reasonably likely to
     have a Material Adverse Effect on Parent: (i) each of Parent and its
     Subsidiaries has complied with all applicable Environmental Laws; (ii)
     neither Parent nor any of its Subsidiaries has received any notice, demand,
     letter, claim or request for information alleging that Parent or any of its
     Subsidiaries may be in violation of or liable under any Environmental Law;
     (iii) neither Parent nor any of its Subsidiaries is subject to any orders,
     decrees, injunctions or other arrangements with any Governmental Entity or
     is subject to any indemnity or other agreement with any third party
     relating to liability under any Environmental Law or relating to Hazardous
     Substances; and (iv) there are no circumstances or conditions involving
     Parent or any of its Subsidiaries that could reasonably be expected to
     result in any claims, liability, investigations, costs or restrictions on
     the ownership, use, or transfer of any of Parent's properties pursuant to
     any Environmental Law.

          (k) Taxes. Except to the extent of any inaccuracy or incompleteness of
     any of the following which is not, individually or in the aggregate,
     reasonably likely to have a Material Adverse Effect on Parent, (i) Parent
     and each of its Subsidiaries have prepared or will prepare in good faith
     and duly and timely filed (taking into account any extension of time within
     which to file), or will so file, all material Tax Returns required to be
     filed by any of them at or before the Effective Time and all such filed Tax
     Returns are or will be complete and accurate, (ii) Parent and each of its
     Subsidiaries as of the Effective Time (x) will have paid all Taxes that
     they are required to pay prior to the Effective Time, and (y) will have
     withheld all federal, state and local income taxes, FICA, FUTA and other
     Taxes, including, without limitation, similar foreign Taxes, required to be
     withheld from amounts owing to any employee, creditor or third party, (iii)
     as of the date of this Agreement, there are not pending or threatened in
     writing, any audits, examinations, investigations or other proceedings in
     respect of Taxes or Tax matters, (iv) there are not, to the actual
     knowledge of Parent's executive officers, any unresolved questions, claims
     or outstanding proposed or assessed deficiencies concerning

                                      A-22
<PAGE>   95

     Parent or any of its Subsidiaries' Tax liability, (v) neither Parent nor
     any of its Subsidiaries has any liability with respect to income, franchise
     or similar Taxes in excess of the amounts accrued in respect of such Taxes
     that are reflected in the financial statements included in Parent's Reports
     and (vi) neither Parent nor any of its Subsidiaries has executed any waiver
     of any statute of limitations on, or extended the period for the assessment
     or collection of, any Tax.

                                  ARTICLE VI.

        its Subsidiaries with respect to matters specifically addressed by any

        its wholly-owned Subsidiaries or between wholly-owned Subsidiaries of
        the Company, neither it nor any of its Subsidiaries shall incur, repay
        or retire prior to maturity or refinance any indebtedness for borrowed

        for the use of foreign bank lines of credit in the ordinary course;

             (vi) Neither it nor any of its Subsidiaries shall (A) make any

             (viii) Except as permitted by Sections 6.2 and 8.3(b), neither it
        nor any of its Subsidiaries shall authorize, propose or announce an
        intention to authorize or propose or enter into an agreement with
        respect to, any merger, consolidation or business combination (other

             (xi) Neither it nor any of its Subsidiaries shall authorize or
        enter into any agreement to do any of the foregoing.

          (b) Parent covenants and agrees as to itself and its Subsidiaries
     that, after the date of this Agreement and prior to the Effective Time
     (unless the Company shall otherwise approve in writing and except as

     expressly contemplated by this Agreement or the Stock Option Agreement):

             (i) It shall not: (A) amend its certificate of incorporation or

        shares of

                                      A-24
<PAGE>   97

        capital stock; (C) declare, set aside or pay any dividend on the Parent
        Common Stock or other capital stock of Parent payable in cash, stock or
        property in respect of any such capital stock (other than regular
        quarterly dividends on the Parent Common Stock consistent with past

        Parent Common Stock after the Effective Time); or (D) repurchase, redeem
        or otherwise acquire, except in connection with existing commitments
        under Parent's employee benefit plans but subject to Parent's
        obligations under subparagraph (iii) below, or permit any of its
        Subsidiaries to purchase or otherwise acquire, any shares of its capital
        stock or any securities convertible into or exchangeable or exercisable
        for any shares of its capital stock;

             (ii) Neither it nor any of its Subsidiaries shall take any action
        that would prevent the Merger from qualifying for "pooling-of-interests"
        accounting treatment in accordance with the Pooling Requirements or as a
        "reorganization" within the meaning of Section 368(a) of the Code; and

             (iii) Neither it nor any of its Subsidiaries shall authorize or
        enter into any agreement to do any of the foregoing.

          (c) Parent and the Company agree that any written approval obtained
     under Section 6.1(a) must be signed by the Chief Executive Officer or

     Executive Officer or Senior Vice President, General Counsel and Secretary
     of the Company.

          (d) Parent and the Company agree that prior to the Closing, the record
     date for determining shareholders of the Company or Parent entitled to
     receive the regular quarterly dividends permitted hereunder that may be
     declared by the board of directors of either Parent or the Company after
     the date of this Agreement but prior to the Closing shall be the close of
     business on the day on which Parent's then current fiscal quarter ends.

     6.2. Acquisition Proposals.

          (a) The Company agrees that it shall not nor shall it knowingly permit
     any of its Subsidiaries or any of the officers and directors of it or its
     Subsidiaries to, and that it shall direct and use its reasonable best
     efforts to cause its and its Subsidiaries' employees, agents and
     representatives (including any investment banker, attorney or accountant
     retained by it or any of its Subsidiaries) (the Company, its Subsidiaries
     and their officers, directors, employees, agents and representatives being
     referred to as the "Company Representatives") not to, directly or
     indirectly, initiate, solicit, or knowingly encourage or otherwise
     intentionally facilitate any inquiries or the making of any proposal or
     offer with respect to a merger, reorganization, share exchange,
     consolidation, business combination, recapitalization, liquidation,
     dissolution or similar transaction involving the Company, or any purchase
     or sale of the consolidated assets (including without limitation stock of
     Subsidiaries) of the Company or any of its Subsidiaries, taken as a whole,
     having an aggregate value equal to 15% or more of the Company's market
     capitalization, or any purchase or sale of, or tender or exchange offer
     for, 15% or more of its equity securities (any such proposal or offer being
     hereinafter referred to as an "Acquisition Proposal"). The Company further
     agrees that it shall not nor shall it knowingly permit any of its
     Subsidiaries or any of the officers and directors of it or its Subsidiaries
     to, and that it shall direct and use its reasonable best efforts to cause
     the Company Representatives not to, directly or indirectly, have any
     discussion in furtherance of or provide any confidential information or
     data to any Person relating to an Acquisition Proposal or engage in any
     negotiations concerning an Acquisition Proposal, or otherwise intentionally
     facilitate any effort or attempt to make or implement an Acquisition
     Proposal; provided, however ,that nothing contained in this Agreement shall
     prevent either the Company or its Board of Directors from: (A) complying
     with Rules 14d-9 and 14e-2 promulgated under the Exchange Act with regard
     to an Acquisition Proposal; (B) if the Board of Directors of the Company
     determines in good faith after consultation with outside counsel, that in
     order for the Board of Directors of the Company to comply with its
     fiduciary duties to stockholders under applicable law
                                      A-25
<PAGE>   98

     it should take such action, engaging in any discussions or negotiations
     with or providing any information or data to any Person (including its
     Representatives) in response to an unsolicited written Acquisition Proposal
     by any such Person; provided, that prior to providing any information or
     data to any Person in connection with an Acquisition Proposal by any such
     Person, the Board of Directors of the Company shall receive from such
     Person an executed confidentiality agreement on terms substantially similar
     to those contained in the confidentiality agreement previously entered into
     between Parent and the Company in connection with their consideration of
     the Merger; provided further, that such confidentiality agreement shall
     contain terms that allow the Company to comply with its obligations under
     this Section 6.2 or (C) recommending such an unsolicited written
     Acquisition Proposal to the stockholders of the Company if, and only to the
     extent that, with respect to the actions referred to in clause (C), (i) the
     Board of Directors of the Company concludes in good faith (after
     consultation with its outside legal counsel and its financial advisor) that
     such Acquisition Proposal is reasonably capable of being completed, and
     would, if consummated, result in a transaction more favorable to the
     Company's stockholders than the Merger (a "Superior Proposal"), and (ii)
     the Board of Directors of the Company determines in good faith after
     consultation with outside legal counsel that the failure to take such
     action would be reasonably likely to be inconsistent with its fiduciary
     duty to the Company's stockholders under applicable Law.

          (b) Except as disclosed in Section 6.1(a) of the Company Disclosure
     Letter, the Company agrees that it will immediately cease and cause to be
     terminated any existing activities, discussions or negotiations with any
     parties conducted heretofore with respect to any Acquisition Proposal. The
     Company agrees that it will promptly inform its executive officers,
     directors, attorneys and financial advisors of the obligations undertaken
     in Section 6.2(a). The Company agrees that it will notify Parent as soon as
     reasonably practicable, if any such proposals or offers are received by it,
     any such information is requested from it or any such discussions or
     negotiations are sought to be initiated with it, indicating, in connection
     with such notice, the name of such Person making such inquiry, proposal,
     offer or request and a description of the substance of any such inquiries,
     proposals, offers or requests. The Company thereafter shall keep Parent
     informed as soon as reasonably practicable, of the status and terms of any
     such inquiries, proposals or offers.

     6.3. Information Supplied. The Company and Parent each agrees, as to itself
and its Subsidiaries, that none of the information supplied or to be supplied by
it or its Subsidiaries for inclusion or incorporation by reference in (i) the
Registration Statement on Form S-4 to be filed with the SEC by Parent in
connection with the issuance of shares of Parent Common Stock in the Merger
(including the joint proxy statement of Parent and the Company and prospectus of
Parent (the "Prospectus/Proxy Statement") constituting a part thereof) (the "S-4
Registration Statement") will, at the time the S-4 Registration Statement
becomes effective under the Securities Act, and (ii) the Prospectus/Proxy
Statement and any amendment or supplement thereto will, at the date of mailing
to stockholders and at the time of the meetings of stockholders of the Company
and Parent to be held in connection with the Merger, in any such case, contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. If at any time prior to the Effective Time any information relating
to Parent or the Company, or any of their respective Affiliates, officers or
directors, is discovered by Parent or the Company which should be set forth in
an amendment or supplement to any of the S-4 Registration Statement or the
Prospectus/Proxy Statement, so that any of such documents would not include any
misstatement of a material fact or would omit to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, the
party which discovers such information shall promptly notify the other parties
to this Agreement and an appropriate amendment or supplement describing such
information shall be promptly filed with the SEC and, to the extent required by
law, disseminated to the stockholders of the Company and Parent.

                                      A-26
<PAGE>   99

     6.4. Stockholders Meetings.

          (a) The Company will take, in accordance with applicable Law and its
     certificate of incorporation and bylaws, all action necessary to convene a
     meeting of holders of Company Shares (the "Company Stockholders Meeting")
     as promptly as reasonably practicable after the S-4 Registration Statement
     is declared effective to consider and vote upon the adoption of this
     Agreement. The Company's Board of Directors shall (i) recommend that the
     stockholders of the Company adopt this Agreement and thereby approve the
     transactions contemplated by this Agreement and (ii) solicit such adoption
     (including soliciting proxies); provided, however, that the Company's Board
     of Directors may, at any time prior to the Effective Time, withdraw, modify
     or change any such recommendation to the extent that the Company's Board of
     Directors determines in good faith, after consultation with outside legal
     counsel, that the failure to take such action would be reasonably likely to
     be inconsistent with its fiduciary duties to the Company's stockholders
     under applicable Law.

          (b) Parent will take, in accordance with applicable Law and its
     certificate of incorporation and bylaws, all action necessary to convene a
     meeting of its stockholders (the "Parent Stockholders Meeting") as promptly
     as reasonably practicable after the S-4 Registration Statement is declared
     effective to consider and vote upon the issuance of the aggregate Merger
     Consideration pursuant to this Agreement. The Board of Directors of Parent
     shall: (i) recommend that the stockholders approve the issuance of the
     Merger Consideration pursuant to this Agreement; and (ii) solicit such
     approval (including soliciting proxies). Notwithstanding the foregoing, at
     any time following determination of the Exchange Ratio but prior to the
     Parent Stockholders Meeting, Parent may cancel and not convene the Parent
     Stockholders Meeting if the rules and listing policies of the NYSE do not
     require the stockholders of Parent to approve the issuance of the Merger
     Consideration in the Merger.

     6.5. Filings; Other Actions; Notification.

          (a) Parent and the Company shall promptly prepare and file with the
     SEC the Prospectus/Proxy Statement, and Parent shall prepare and file with
     the SEC the S-4 Registration Statement as promptly as practicable. Parent
     and the Company each shall use its reasonable best efforts to have the S-4
     Registration Statement declared effective under the Securities Act as
     promptly as practicable after such filing, and promptly thereafter mail the
     Prospectus/Proxy Statement to the stockholders of the Company and to the
     stockholders of Parent. Parent shall also use its reasonable best efforts
     to obtain prior to the effective date of the S-4 Registration Statement all
     necessary state securities law or "blue sky" permits and approvals required
     in connection with the Merger and the other transactions contemplated by
     this Agreement and will pay all expenses incident thereto.

          (b) The Company and Parent each shall use its respective reasonable
     best efforts to cause to be delivered to the other party and its directors
     letters of its independent auditors, dated (i) the date on which the S-4
     Registration Statement shall become effective and (ii) the Closing Date,
     and addressed to the other party and its directors, in form customary for
     "comfort" letters delivered by independent public accountants in connection
     with registration statements similar to the S-4 Registration Statement.

          (c) The Company and Parent shall cooperate with each other and,
     subject to Sections 6.5(d) and (e), use (and shall cause their respective
     Subsidiaries to use) their respective reasonable best efforts (i) to take
     or cause to be taken all actions, and do or cause to be done all things,
     necessary, proper or advisable on their part under this Agreement and the
     Stock Option Agreement and applicable Laws to consummate and make effective
     the Merger and the other transactions contemplated by this Agreement and
     the Stock Option Agreement as soon as practicable, including (A) obtaining
     comfort letters and opinions of their respective accountants and attorneys
     referred to in Section 6.5(b) and Article VII of this Agreement, (B)
     preparing and filing as promptly as practicable all documentation,
     including all additional information requested by any Governmental Entity,
     to effect all necessary applications, notices, petitions, filings and other
     documents (including under the HSR Act (as defined below) and other
     Competition Laws (as defined below)), and (C) instituting court actions and
     other proceedings necessary to obtain the approval or clearance required
     to, or have
                                      A-27
<PAGE>   100

     lifted any injunction or order which would not permit the parties hereto
     to, consummate the Merger or the other transactions contemplated by this
     Agreement and the Stock Option Agreement or defending or otherwise opposing
     all court actions and other proceedings instituted by a Governmental Entity
     or other Person under the Competition Laws or otherwise for purposes of
     preventing the consummation of the Merger and the other transactions
     contemplated by this Agreement and the Stock Option Agreement and (ii) to
     obtain as promptly as practicable all consents, clearances, registrations,
     approvals, permits and authorizations and to achieve the termination or
     expiration of all applicable waiting periods necessary or advisable to be
     obtained from any Governmental Entity in order to consummate the Merger and
     the other transactions contemplated by this Agreement and the Stock Option
     Agreement. Subject to applicable Laws and existing obligations relating to
     the exchange of information, Parent and the Company shall have the right to
     review in advance, and to the extent practicable each will consult the
     other on, all the information relating to Parent or the Company, as the
     case may be, and any of their respective Subsidiaries, that appear in any
     filing made with, or written materials submitted to, any third party and/or
     any Governmental Entity in connection with the Merger and the other
     transactions contemplated by this Agreement and the Stock Option Agreement.
     In exercising the foregoing right, each of the Company and Parent shall act
     reasonably and as promptly as practicable, including by (i) permitting the
     other party to review and discuss in advance, and considering in good faith
     the views of one another in connection with, any proposed written (or any
     material proposed oral) communication with any Governmental Entity, (ii)
     not participating in any meeting with any Governmental Entity unless it
     consults with the other party in advance and to the extent permitted by
     such Governmental Entity gives the other party the opportunity to attend
     and participate thereat, and (iii) furnishing the other party with such
     necessary information and reasonable assistance as such other party may
     reasonably request in connection with its preparation of necessary filings
     or submissions of information to any Governmental Entity; provided,
     however, that subject to its obligations hereunder Parent shall have the
     right to direct the strategy of the parties in a manner consistent with the
     terms of this Agreement in any communications, meetings or proceedings with
     any Governmental Entity in connection with the Merger and the other
     transactions contemplated by this Agreement and the Stock Option Agreement.
     The Company and Parent may, as each deems advisable and necessary,
     reasonably designate any competitively sensitive material provided to the
     other under this Section as "outside counsel only." Such materials and the
     information contained therein shall be given only to the outside legal
     counsel to the recipient and will not be disclosed by such outside counsel
     to employees, officers, or directors of the recipient unless express
     permission is obtained in advance from the source of the materials (the
     Company or Parent, as the case may be) or its legal counsel.

          (d) Notwithstanding anything to the contrary in this Agreement, (i)
     the Company shall not, without Parent's prior written consent, commit to
     any divestitures, licenses, hold separate arrangements or similar matters,
     including covenants affecting business operating practices (or allow its
     Subsidiaries to commit to any divestitures, licenses, hold separate
     arrangements or similar matters), and the Company shall commit to, and
     shall use reasonable best efforts to effect (and shall cause its
     Subsidiaries to commit to and use reasonable best efforts to effect), any
     such divestitures, licenses, hold separate arrangements or similar matters
     as Parent shall request, but solely if such divestitures, licenses, hold
     separate arrangements or similar matters are contingent on consummation of
     the Merger and (ii) neither Parent nor any of its Subsidiaries shall be
     required (pursuant to Section 6.5(c) or otherwise) to agree (with respect
     to (x) Parent or its Subsidiaries or (y) the Company or its Subsidiaries)
     to any divestitures, licenses, hold separate arrangements or similar
     matters, including covenants affecting business operating practices, if
     such divestitures, licenses, arrangements or similar matters, individually
     or in the aggregate, would reasonably be expected to have a Material
     Adverse Effect on Parent or the Company.

          (e) Except as provided below, nothing in this Section 6.5 or any other
     part of this Agreement shall require Parent to refrain from entering into
     any agreement with respect to, or issuing Parent Common Stock or other
     consideration in connection with, a business combination with, or an
     acquisition of, a third party after the date of this Agreement and prior to
     the Effective Time
                                      A-28
<PAGE>   101

     (a "Subsequent Transaction"); provided, however, that (i) the aggregate
     fair market value of the consideration paid or to be paid by Parent in all
     such Subsequent Transactions shall not exceed $1.5 billion and the fair
     market value of the consideration paid or to be paid by Parent in any
     individual Subsequent Transaction shall not exceed $750 million (provided
     that these amounts may be exceeded with the consent of the Company's Chief
     Executive Officer) and (ii) Parent has a good faith belief at the time it
     enters into the definitive agreement calling for any such Subsequent
     Transaction that such Subsequent Transaction is not reasonably likely to
     prevent or delay satisfaction of any of the conditions set forth in Article
     VII. In the event of a Subsequent Transaction which would be permissible
     under the preceding sentence, Parent shall agree to any divestitures,
     licenses, hold separate arrangements or similar matters (including
     covenants affecting business operating practices) necessary in order to
     obtain approval of the transactions contemplated by this Agreement under
     applicable Competition Laws that would not otherwise have been required in
     order to obtain such approval but for the Subsequent Transaction.

          (f) The Company and Parent each shall, upon request by the other and
     subject to applicable laws and existing obligations relating to the
     exchange of information, furnish the other with all information concerning
     itself, its Subsidiaries, directors, officers and stockholders and such
     other matters as may be reasonably necessary or advisable in connection
     with the Prospectus/Proxy Statement, the S-4 Registration Statement or any
     other statement, filing, notice or application made by or on behalf of
     Parent, the Company or any of their respective Subsidiaries to any third
     party and/or any Governmental Entity in connection with the Merger and the
     transactions contemplated by this Agreement and the Stock Option Agreement.

          (g) The Company and Parent each shall keep the other apprised of the
     status of matters relating to completion of the transactions contemplated
     by this Agreement and the Stock Option Agreement, including promptly
     furnishing the other with copies of notice or other communications received
     by Parent or the Company, as the case may be, or any of its Subsidiaries,
     from any Governmental Entity with respect to the Merger and the other
     transactions contemplated by this Agreement and the Stock Option Agreement.

     6.6. Access; Consultation.

          (a) Upon reasonable notice, and except as may be prohibited by
     applicable Law, each of the Company and Parent shall (and shall cause its
     respective Subsidiaries to) afford to the other employees, agents and
     representatives (including any investment banker, attorney or accountant
     retained by the other or any of its Subsidiaries) reasonable access, during
     normal business hours throughout the period prior to the Effective Time, to
     its properties, books, contracts and records and, during such period, it
     shall (and shall cause its Subsidiaries to) furnish promptly to the other
     all information concerning its business, properties and personnel as may
     reasonably be requested; provided that no investigation pursuant to this
     Section 6.6(a) shall affect or be deemed to modify any representation or
     warranty made by the Company or Parent under this Agreement; and provided,
     further, that the foregoing shall not require the Company to permit any
     inspection, or to disclose any information, that in the reasonable judgment
     of such party would result in the disclosure of any trade secrets of third
     parties or the waiver of any privilege or violate any of such party's
     obligations with respect to confidentiality if such party shall have used
     all reasonable efforts to obtain the consent of such third party to such
     inspection or disclosure or to preserve such privilege. All requests for
     information made pursuant to this Section 6.6(a) shall be directed to an
     executive officer of the Company or Parent, or such Person as may be
     designated by any such executive officer, as the case may be.

          (b) Subject to applicable Laws relating to the exchange of
     information, from the date of this Agreement to the Effective Time, the
     Company agrees to consult with Parent on a regular basis on a schedule to
     be agreed with regard to the Company's operations.

                                      A-29
<PAGE>   102

          (c) Prior to the Closing, the Company will provide to Parent a
     worldwide list of all patents, trade names, registered trademarks and
     registered service marks, and applications for any of the foregoing, owned
     or possessed by the Company or any of its Subsidiaries.

     6.7. Affiliates.

          (a) Each of the Company and Parent shall deliver to the other a letter
     identifying all Persons whom such party believes to be, at the date of the
     Company Stockholders Meeting, affiliates of such party for purposes of
     applicable interpretations regarding use of the pooling-of-interests
     accounting method ("Pooling Affiliates") and, in the case of the Company,
     affiliates of the Company for purposes of Rule 145 under the Securities Act
     ("Rule 145 Affiliates"). Each of the Company and Parent shall use all
     reasonable efforts to cause each Person who is identified as a Pooling
     Affiliate or Rule 145 Affiliate in the letter referred to above to deliver
     to Parent on or prior to the date of the Company Stockholders Meeting a
     written agreement, in the form attached as Exhibit 6.7(A), in the case of a
     Pooling Affiliate or Rule 145 Affiliate of the Company (the "Company
     Affiliate's Letter"), and Exhibit 6.7(B) (or Exhibit 6.7(C) as applicable),
     in the case of a Pooling Affiliate of Parent (the "Parent Affiliate's
     Letter"). Prior to the Effective Time, each of the Company and Parent shall
     use all reasonable efforts to cause each additional Person who is
     identified by such party as its Pooling Affiliate or by the Company as a
     Rule 145 Affiliate after the date of the Company Stockholders Meeting to
     execute the applicable written agreement as set forth in this Section 6.7,
     as soon as practicable after such Person is identified.

          (b) Shares of Parent Common Stock issued to Pooling Affiliates of the
     Company in exchange for Company Shares shall not be transferable until such
     time as financial results covering at least 30 days of combined operations
     of Parent and the Company shall have been published within the meaning of
     Section 201.01 of the SEC's Codification of Financial Reporting Policies,
     regardless of whether each such Pooling Affiliate has provided the written
     agreement referred to in this Section, except to the extent permitted by,
     and in accordance with, SEC Accounting Series Release 135 and SEC Staff
     Accounting Bulletins 65 and 76. The Company shall not register the transfer
     of any Certificate unless such transfer is made in compliance with the
     foregoing.

     6.8. Stock Exchange Listing. To the extent they are not already listed,
Parent shall use its reasonable best efforts to cause the shares of Parent
Common Stock to be issued in the Merger to be approved for listing on the NYSE
and on all other stock exchanges on which shares of Parent Common Stock are then
listed, subject to official notice of issuance, prior to the Closing Date.

     6.9. Publicity. The initial press release with respect to the Merger shall
be a joint press release. Thereafter, unless otherwise required by applicable
law or pursuant to any listing agreement with or rules of a securities exchange,
the Company and Parent shall consult with each other prior to issuing any press
releases or otherwise making public announcements with respect to the Merger and
the other transactions contemplated by this Agreement and prior to making any
filings with any third party and/or any Governmental Entity (including any
securities exchange) with respect thereto.

     6.10. Benefits.

          (a) Stock Options.

             (i) At the Effective Time, each outstanding option to purchase
        Company Shares (a "Company Option") under the Company Stock Plans,
        whether vested or unvested, shall be converted to an option to acquire
        the same number of shares of Parent Common Stock as the holder of such
        Company Option would have been entitled to receive pursuant to the
        Merger had such holder exercised such Company Option in full immediately
        prior to the Effective Time (rounded down to the nearest whole number)
        (a "Substitute Option"), at an exercise price per share (rounded to the
        nearest whole cent) equal to (y) the aggregate exercise price for the
        Company Shares otherwise purchasable pursuant to such Company Option
        divided by (z) the number of full shares of Parent Common Stock deemed
        purchasable pursuant to such Company Option in accordance with the
        foregoing. To illustrate the foregoing, a Company Option
                                      A-30
<PAGE>   103

        outstanding immediately prior to the Effective Time that entitles the
        holder to purchase 1,000 Company Shares for an aggregate exercise price
        of $25,000 would be converted at the Effective Time into a Substitute
        Option to purchase [1,000 * Exchange Ratio] shares of Parent Common
        Stock for an exercise per share of Parent Common Stock of $[25,000 /
        (1,000 * Exchange Ratio)].

             (ii) As promptly as practicable after the Effective Time, the
        Company shall deliver to the participants in the Company Stock Plans
        appropriate notices setting forth such participants' rights pursuant to
        the Substitute Options.

          (b) Conversion and Registration. At or prior to the Effective Time,
     the Company shall make all necessary arrangements with respect to the
     Company Stock Plans to permit the conversion of the unexercised Company
     Options into Substitute Options pursuant to this Section and register under
     the Securities Act on Form S-8 or other appropriate form (and use its best
     efforts to maintain the effectiveness thereof) shares of Parent Common
     Stock issuable pursuant to all Substitute Options with respect to Parent
     Common Stock not later than three business days after the Effective Time.

          (c) Prior to the Effective Time, the Board of Directors of Parent, or
     an appropriate committee of non-employee directors thereof, shall adopt a
     resolution consistent with the interpretive guidance of the SEC so that the
     acquisition by any officer or director of the Company who may become a
     covered person of Parent for purposes of Section 16 of the Exchange Act and
     the rules and regulations thereunder ("Section 16") of shares of Parent
     Common Stock or options to acquire Parent Common Stock pursuant to this
     Agreement and the Merger shall be an exempt transaction for purposes of
     Section 16.

          (d) From and after the Effective Time, Parent in its sole discretion
     shall either itself assume or cause one of its Affiliates to assume, or
     shall cause the Company to continue to maintain, the Compensation and
     Benefit Plans in effect immediately before the Effective Time; provided
     that nothing shall prevent Parent or its Affiliates or the Company or its
     Affiliates from amending or terminating any Compensation or Benefit Plan to
     the extent permitted by its terms or applicable law.

          (e) For purposes of determining the eligibility of any individual
     employed by the Company or any of its Subsidiaries immediately before the
     Effective Time (a "Company Employee") to participate in and have vested
     rights under the employee benefit plans of Parent and its Affiliates
     providing benefits to Company Employees after the Effective Time, each
     Company Employee shall be credited with his or her years of service with
     the Company and its Affiliates before the Effective Time, to the same
     extent as such Company Employee was entitled, before the Effective Time, to
     credit for any such service under similar Compensation and Benefit Plans.
     "Eligibility" for purposes of this paragraph (e) shall mean (i) eligibility
     to participate in any such employee benefit plan, (ii) eligibility for
     post-retirement health and life benefits (to the extent such benefits are
     conditioned on the satisfaction of specified age and service requirements)
     and (iii) eligibility for early retirement under any employee pension
     benefit plan of Parent and its Affiliates (to the extent that early
     retirement is conditioned on the satisfaction of specified age and service
     requirements). Years of service with the Company and its Affiliates prior
     to the Effective Time shall also be recognized: (i) under any severance,
     separation pay or vacation pay plan or policy of Parent and its Affiliates
     extended to Company Employees after the Effective Time for purposes of
     determining the amount of a Company Employee's benefit under such plan or
     policy; (ii) under any savings, 401(k) or other defined contribution plan
     in which any Company Employee participates after the Effective Time for
     purposes of determining the amount of employer contributions to such
     Company Employee's account thereunder (to the extent service is relevant
     for that purpose); and (iii) under any plan providing welfare benefits in
     which any Company Employee participates after the Effective Time for
     purposes of determining the level of benefits and the amounts the Company
     Employee is required to pay with respect thereto (including without
     limitation premiums, co-payments, deductibles and the like), to the extent
     service is relevant for those purposes, but only with respect to Company
     Employees who are eligible for that category of welfare benefit (such as
     post-retirement health care) under a

                                      A-31
<PAGE>   104

     Compensation and Benefit Plan on the date of this Agreement, or who would
     be so eligible if they had met the requisite age and service requirements
     for eligibility. For purposes of determining a Company Employee's benefits
     under a pension benefit plan which is merged with or has its assets and
     liabilities transferred to an employee benefit plan of Parent or its
     Affiliates after the Effective Time, such benefit shall not be less than
     the benefit to which any affected Company Employee would be entitled had
     the Company employee benefit plan been frozen at the time of such merger or
     transfer and the Parent or Affiliate employee benefit plan began accruing
     benefits from and after the date of such merger or transfer. In addition,
     and without limiting the generality of the foregoing, to the extent
     permitted by applicable law, if a Company Employee participates,
     immediately before the Effective Time, in a pension benefit plan under
     which such Company Employee accrues a benefit based upon final average pay
     (as opposed to career average pay), and such Company pension benefit plan
     is merged into a pension benefit plan of Parent or one of its Affiliates
     that continues to provide a benefit based upon final average pay, such
     Company Employee's pay increases from the Company and its Affiliates after
     the Effective Time shall be applied to his or her pre-Effective Time
     service and benefit formula, except to the extent such application would
     result in a duplication of benefits, so that such Company Employee's
     combined pension benefit under the merged plan will reflect his or her
     final average pay following the Effective Time as applied to all years of
     service, both before and after the Effective Time, under whichever formula
     is relevant to the different periods of service. Furthermore, and without
     limiting the generality of the foregoing, for purposes of each employee
     benefit plan sponsored by the Parent and its Affiliates which provides for
     medical, dental, pharmaceutical and/or vision benefits to any Company
     Employee, Parent shall cause all pre-existing condition exclusions and
     actively-at-work requirements of such new employee benefit plan to be
     waived for such Employee and his or her covered dependents and to have any
     eligible expenses incurred by such Employee and his or her covered
     dependents during the portion of the plan year of a prior plan ending on
     the date such employee's participation in a replacement plan, begins to be
     taken into account under such replacement 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 replacement plan. No provision in the foregoing shall be construed as
     requiring Parent or any of its Affiliates to extend participation in any
     employee benefit plan sponsored by Parent or any of its Affiliates to any
     Company Employee. In addition, the foregoing provisions of this paragraph
     (e) shall not apply to any benefits that are the subject of collective
     bargaining, and nothing in this paragraph (e) shall limit or restrict the
     right of Parent or any of its Affiliates to amend or terminate any of their
     employee benefit plans at any time.

     6.11. Expenses. Whether or not the Merger is consummated, all costs and
expenses incurred in connection with this Agreement and the Merger and the other
transactions contemplated by this Agreement shall be paid by the party incurring
such expense, except that expenses incurred in connection with the filing fee
for the S-4 Registration Statement, printing and mailing the Prospectus/Proxy
Statement, the S-4 Registration Statement and the filing fees under the HSR Act
and any other Competition Law filings shall be paid by Parent.

     6.12. Indemnification; Directors' and Officers' Insurance.

          (a) From and after the Effective Time, (i) Parent will, and will cause
     the Surviving Corporation to, indemnify and hold harmless each present and
     former director or officer of the Company and (ii) Parent will cause the
     Surviving Corporation to indemnify and hold harmless each present or former
     director or officer of any subsidiary or division of the Company and each
     person who served at the request of the Company as a director, officer,
     trustee or fiduciary of another corporation, partnership, joint venture,
     trust, pension, or other employee benefit plan or enterprise (the Persons
     indemnified under (i) and (ii) being the "Indemnified Parties"), in the
     case of (i) and (ii), against any costs or expenses (including reasonable
     attorneys' fees), judgments, fines, losses, claims, damages or liabilities
     and amounts paid in settlement (provided that no such settlement is entered
     into without the approval of Parent or the Surviving Corporation, which
     approval shall not be unreasonably withheld) (collectively, "Costs")
     incurred in connection with any claim, action, suit, proceeding or
                                      A-32
<PAGE>   105

     investigation, whether civil, criminal, administrative or investigative,
     arising out of or pertaining to matters existing or occurring at or prior
     to the Effective Time relating to the Indemnified Party's service with or
     at the request of the Company, whether asserted or claimed prior to, at or
     after the Effective Time, to the fullest extent permitted under Law (in the
     case of (i)) and to the fullest extent the Company would have been
     permitted to so indemnify under Delaware law (in the case of (ii)). In the
     case of (i), Parent shall, and shall cause the Surviving Corporation to,
     advance expenses to the fullest extent permitted under applicable Law,
     provided that, if required under applicable Law, the Person to whom
     expenses are advanced shall provide an undertaking to repay such advances
     if it is ultimately determined that such Person is not entitled to
     indemnification. In the case of (ii), Parent shall cause the Surviving
     Corporation to advance expenses as incurred to the fullest extent permitted
     under Delaware law, provided that the Person to whom expenses are advanced
     shall provide an undertaking to repay such advances if it is ultimately
     determined that such Person is not entitled to indemnification. The
     indemnification rights hereunder shall be in addition to any other rights
     such Indemnified Party may have under the Certificate of Incorporation and
     Bylaws of the Surviving Corporation or any of its Subsidiaries, under the
     DGCL or otherwise. The Certificate of Incorporation and Bylaws of the
     Surviving Corporation shall contain, and Parent shall cause the Surviving
     Corporation to fulfill and honor, provisions with respect to
     indemnification and exculpation that are at least as favorable to the
     Indemnified Parties as those set forth in the certificate of incorporation
     and bylaws of the Company as of the date of this Agreement, which
     provisions shall not be amended, repealed or otherwise modified for a
     period of six years from the Effective Time in any manner that would
     adversely affect the rights thereunder of any of the Indemnified Parties.
     The parties agree that the provisions relating to exoneration of directors
     and officers and the rights to indemnification, including provisions
     relating to advances of expenses incurred in defense of any action or suit,
     in the certificate of incorporation and bylaws of Company and its
     Subsidiaries with respect to matters occurring through the Effective Time,
     shall survive the Merger and shall continue in full force and effect for a
     period of six years from the Effective Time; provided, however, that all
     rights to indemnification in respect of any action pending or asserted or
     claim made within such period shall continue until the disposition of such
     action or resolution of such claim.

          (b) Any Indemnified Party wishing to claim indemnification under
     paragraph (a) of this Section 6.12 shall promptly notify Parent and the
     Surviving Corporation, upon learning of any such claim, action, suit,
     proceeding or investigation, but the failure to so notify shall not relieve
     Parent and the Surviving Corporation of any liability they may have to such
     Indemnified Party if such failure does not materially prejudice Parent and
     the Surviving Corporation. In the event of any such claim, action, suit,
     proceeding or investigation (whether arising before or after the Effective
     Time), (i) Parent or the Surviving Corporation shall have the right to
     assume the defense thereof (unless the Indemnified Parties (or any of them)
     determine in good faith (after consultation with legal counsel) that there
     are issues which raise conflicts of interest between an Indemnified Party,
     on the one hand, and Parent and the Surviving Corporation on the other
     hand), and Parent and the Surviving Corporation shall not be liable to such
     Indemnified Parties for any legal expenses of other counsel or any other
     expenses subsequently incurred by such Indemnified Parties in connection
     with the defense thereof (except that if Parent and the Surviving
     Corporation elect not to assume such defense or if there are issues which
     raise conflicts of interest between Parent and the Surviving Corporation,
     on the one hand, and one or more of the Indemnified Parties, on the other,
     the Indemnified Parties may retain counsel satisfactory to them, and Parent
     and the Surviving Corporation shall pay all reasonable fees and expenses of
     such counsel for the Indemnified Parties promptly as statements therefor
     are received); provided, however, that Parent and the Surviving Corporation
     shall be obligated pursuant to this paragraph (b) to pay for only one firm
     of counsel (in addition to local counsel) for all Indemnified Parties in
     any jurisdiction (unless there is such a conflict of interest), (ii) the
     Indemnified Parties will cooperate in the defense of any such matter and
     (iii) Parent and the Surviving Corporation shall not be liable for any
     settlement effected without their prior written consent, which consent
     shall not be unreasonably withheld.

                                      A-33
<PAGE>   106

          (c) Parent shall cause the Surviving Corporation to maintain a policy
     of officers' and directors' liability insurance covering the Indemnified
     Parties for acts and omissions occurring on or prior to the Effective Time
     ("D&O Insurance") with coverage in amount and scope at least as favorable
     as the Company's existing directors' and officers' liability insurance
     coverage for a period of six years after the Effective Time; provided,
     however, if the existing D&O Insurance expires, is terminated or canceled,
     or if the annual premium therefor is increased to an amount in excess of
     200% of the last annual premium paid prior to the date of this Agreement
     (the "Current Premium"), in each case during such six-year period, Parent
     and the Surviving Corporation will use their best efforts to obtain D&O
     Insurance in an amount and scope as great as can be obtained for the
     remainder of such period for a premium not in excess (on an annualized
     basis) of 200% of the Current Premium. The provisions of this Section
     6.12(c) shall be deemed to have been satisfied if prepaid policies have
     been obtained by the Company prior to the Closing, which policies provide
     such directors and officers with coverage for an aggregate period of six
     years with respect to claims arising from facts or events that occurred on
     or before the Effective Time, including, without limitation, in respect of
     the transactions contemplated by this Agreement and for a premium not in
     excess of the aggregate of the premiums set forth in the preceding
     sentence. If such prepaid policies have been obtained by the Company prior
     to the Closing, Parent shall and shall cause the Surviving Corporation to
     maintain such policies in full force and effect, and continue to honor the
     Company's obligations thereunder.

          (d) If Parent or the Surviving Corporation or any of its successors or
     assigns (i) shall consolidate with or merge into any other corporation or
     entity and shall not be the continuing or surviving corporation or entity
     of such consolidation or merger or (ii) shall transfer all or substantially
     all of its properties and assets to any individual, corporation or other
     entity, then and in each such case, proper provisions shall be made so that
     the successors and assigns of Parent or the Surviving Corporation shall
     assume all of the obligations set forth in this Section. Parent shall (in
     the case of Section 6.12(a)(i)), and Parent shall cause the Surviving
     Corporation (in the case of Section 6.12(a)(ii)), to pay all expenses,
     including reasonable attorneys' fees, that may be incurred by the
     Indemnified Parties in successfully enforcing the indemnity and other
     rights in this Section 6.12.

          (e) Parent shall cause the Surviving Corporation to perform its
     obligations under this Section 6.12 and shall, in addition, guarantee, as
     co-obligor with the Surviving Corporation, the performance of such
     obligations by the Surviving Corporation subject to the limits imposed on
     the Surviving Corporation under the DGCL.

          (f) The provisions of this Section are intended to be for the benefit
     of, and shall be enforceable by, each of the Indemnified Parties, their
     heirs and their representatives.

     6.13. Takeover Statute. If any Takeover Statute is or may become applicable
to the Merger or the other transactions contemplated by this Agreement or the
Stock Option Agreement, each of Parent and the Company and its Board of
Directors shall grant such approvals and take such actions as are necessary so
that such transactions may be consummated as promptly as practicable on the
terms contemplated by this Agreement or by the Merger and otherwise act to
eliminate or minimize the effects of such statute or regulation on such
transactions.

     6.14. Confidentiality. The Company and Parent each acknowledges and
confirms that it has entered into a Confidentiality Agreement, dated August 25,
1999 (the "Confidentiality Agreement"), and that the Confidentiality Agreement
shall remain in full force and effect in accordance with its terms.

     6.15. Tax-Free Reorganization. Parent, Merger Sub, and the Company shall
each use all reasonable efforts to cause the Merger to be treated as a
reorganization within the meaning of Section 368(a) of the Code and to obtain an
opinion of its respective counsel as contemplated by Sections 7.2(c) and 7.3(c),
respectively.

                                  ARTICLE VII.

                                   CONDITIONS

     government (or any agency, commission, or department or similar entity of
     such government) of any jurisdiction in which Parent and the Company had,

     expected to have a Material Adverse Effect on the Company), in the case of
     each of

     such representations and warranties speak as of an earlier date) as of the
     Closing Date as though made on and as of the Closing Date, and Parent shall

     officer of the Company to such effect;

     in this Agreement (x) to the extent qualified by Material Adverse Effect
     and (y) to the extent not qualified by Material Adverse Effect shall be
     true and correct (except that this clause (y) shall be deemed satisfied so
     long as any failures of such representations and warranties to be true and
     correct, taken together, would not reasonably be expected to have a
     Material Adverse Effect on Parent), in the case of each of (i) and (ii), as
     of the date of this Agreement and (except to the extent such
     representations and warranties speak as of an earlier date), as of the

terminated and the Merger may be abandoned at any time prior to the Effective

in its sole discretion, to extend the Termination Date for an additional period
of time not to exceed 90 days if all other conditions to consummation of the
Merger are satisfied or capable of then being satisfied and the sole reason that
the Merger has not been consummated by such date is that either (A) the
condition set forth in Section 7.1(c) has not been satisfied due to the failure
to obtain the necessary consents and approvals under applicable Competition Laws
and Parent or the Company are still attempting to obtain such necessary consents
and approvals under applicable Competition Laws or are contesting the refusal of
the relevant Governmental Entities to give such consents or approvals in court
or through other applicable proceedings, or (B) the condition set forth in
Section 7.1(d) has not been satisfied; (ii) the Company Stockholders Meeting
shall have been held and completed and the adoption of this Agreement by the
Company's stockholders referred to in Section 7.1(a) shall not have occurred;

approved by Parent's stockholders pursuant to the rules or listing policies of
the NYSE, the Parent Stockholders Meeting shall have been held and completed and

Agreement referred to in Section 7.1(a) shall not have occurred; or (iv) any
Order of a court of competent jurisdiction permanently restraining, enjoining or
otherwise prohibiting consummation of the Merger shall become final and non-
appealable (whether before or after the adoption or approval by the stockholders
of the Company or Parent); provided, that the right to terminate this Agreement
pursuant to clause (i) above shall not be available to any party that has

Merger may be abandoned at any time prior to the Effective Time, whether before

Company:

          (a) if there has been a material breach by Parent or Merger Sub of any
     representation, warranty, covenant or agreement contained in this Agreement
     which (x) would result in a failure of a condition set forth in Section
     7.3(a) or 7.3(b) and (y) cannot be or is not cured prior to the Termination
     Date; or

          (b) at any time prior to the adoption of this Agreement by the
     Company's stockholders, by reason of a Superior Proposal; provided,
     however, that the Company may not terminate this Agreement pursuant to this
     Section 8.3(b) unless: (i) the Company shall have complied with Section
     6.2; (ii) the Board of Directors of the Company shall have concluded in
     good faith, prior to giving effect to all concessions which may be offered
     the Company by Parent, that such proposal is a Superior Proposal; (iii) the

     Superior Proposal, (B) further notified Parent in such writing that the
     Company intends, not earlier than the fourth business day following such
     notice, to enter into a binding agreement for such Superior Proposal and
     (C) attached the most current written version of such Superior Proposal (or
     a summary containing all material terms and conditions of such Superior
     Proposal) to such notice; and (iv) during such four business day period,
     the Company shall, and shall cause its respective financial and legal
     advisors to, consider any adjustment in the terms and conditions of this
     Agreement that Parent may propose; provided, further, that it shall be a
     condition to termination pursuant to this Section 8.3(b) that the Company
     shall have made the payment of the Termination Fee to Parent required by
     Section 8.5(b).

     8.4. Termination by Parent. This Agreement may be terminated and the Merger
may be abandoned at any time prior to the Effective Time, before or after the

     representation, warranty, covenant or agreement contained in this Agreement
     which (i) would result in a failure of a condition set forth in Section

     Termination Date.

     8.5. Effect of Termination and Abandonment.

          (a) In the event of termination of this Agreement and the abandonment
     of the Merger pursuant to this Article VIII, this Agreement (other than as
     set forth in Section 9.2) shall become void and of no effect with no
     liability (other than as set forth in Section 8.5(b) or in the proviso at
     the end of this sentence) on the part of any party to this Agreement or of
     any of its directors, officers, employees, agents, legal or financial
     advisors or other representatives; provided, however, that no such
     termination shall relieve any party to this Agreement from any liability
     resulting from any breach of this Agreement.

          (b) In the event that (i) an Acquisition Proposal is publicly
     announced and not withdrawn prior to the Company Stockholders Meeting, the
     Board of Directors of the Company shall have withdrawn or materially
     modified, in a manner adverse to Parent, its approval or recommendation of
     this Agreement or the Merger and this Agreement is terminated by the
     Company or Parent pursuant to Section 8.2(ii), (ii) this Agreement is
     terminated by Parent pursuant to Section 8.4(a) (but with respect to
     Section 8.4(a), only if the Board of Directors of the Company shall have
     withdrawn its approval or recommendation of this Agreement or the Merger or
     modified or changed that approval or recommendation to such an extent that
     it is no longer approving or recommending this Agreement or the Merger),
     (iii) an Acquisition Proposal is publicly announced and not withdrawn prior
     to the Company Stockholders Meeting, this Agreement is terminated by the
     Company or Parent pursuant to Section 8.2(ii) and within one year after
     such termination the Company enters into a definitive agreement with
     respect to an Acquisition Proposal or an Acquisition Proposal is
     consummated, in either case with any Person or (iv) this Agreement is
     terminated by the Company pursuant to Section 8.3(b), then the Company
     shall pay Parent a fee equal to $75 million (the "Termination Fee"). In the
     event of a termination by the Company described in clause (i) or (iv) of
     the preceding sentence, the Termination Fee shall be payable by wire
     transfer of same day funds as a condition precedent to such termination; in
     the event the Termination Fee shall become payable pursuant to clause (iii)
     of the preceding sentence, the Termination Fee shall be payable by wire
     transfer of same day funds simultaneously with the execution of the
     definitive agreement or the consummation of the Acquisition Proposal which
     gives rise to the obligation to pay the Termination Fee; and in the event
     of a termination by Parent described in clause (i) or (ii) of the preceding
     sentence, the Termination Fee shall be payable by wire transfer of same day
     funds promptly, but in no event later than two days after the date of such
     termination of this Agreement. For purposes of this Section 8.5(b), the
     definition of "Acquisition Proposal" shall be modified by changing all
     references to "15%" to "50%." The Company acknowledges that the agreements
     contained in this Section 8.5(b) are an integral part of the transactions
     contemplated by this Agreement, and that, without these agreements, Parent
     and Merger Sub would not enter into this Agreement. Accordingly, if the
     Company fails to pay promptly the amount due pursuant to this Section
     8.5(b), and, in order to obtain such payment, Parent or Merger Sub
     commences a suit which results in a judgment against the Company for the
     fee set forth in this paragraph (b), the Company shall pay to Parent or
     Merger Sub its costs and expenses (including reasonable attorneys' fees) in
     connection with such suit, together with interest on the amount of the fee
     at the prime rate of Citibank N.A. in effect on the date such payment was
     required to be made.

                                   EXHIBIT 1

                         FORM OF STOCK OPTION AGREEMENT

     This STOCK OPTION AGREEMENT, dated as of September 9, 1999 (this
"Agreement"), is between PREMARK INTERNATIONAL, INC., a Delaware corporation
("Issuer"), and ILLINOIS TOOLWORKS INC., a Delaware corporation ("Grantee").

                                    RECITALS

     A. The Merger Agreement. Prior to the entry into this Agreement and prior
to the grant of the Option (as defined in Section 1(a)), Issuer, Grantee, and CS
Merger Sub Inc., a wholly owned subsidiary of Grantee ("Merger Sub") have
entered into an Agreement and Plan of Merger, dated as of the date of this
Agreement (the "Merger Agreement"), pursuant to which Grantee and Issuer intend
to effect a merger of Merger Sub with and into Issuer (the "Merger").

     B. The Stock Option Agreement. As an inducement and condition to Grantee's
and Merger Sub's willingness to enter into the Merger Agreement, and in
consideration thereof, the board of directors of Issuer has approved the grant
to Grantee of the Option pursuant to this Agreement and the acquisition of
Common Stock (as defined below) by Grantee pursuant to this Agreement; provided,
that such grant was expressly conditioned upon, and made of no effect until
after, execution and delivery by Issuer, Grantee and Merger Sub of the Merger
Agreement.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth in this Agreement and in the Merger Agreement, the
parties agree as follows:

     1. The Option. (a) Issuer hereby grants to Grantee an irrevocable option
(the "Option") to purchase, subject to the terms and conditions of this
Agreement, up to 12,203,694 fully paid and nonassessable shares of common stock,
$1.00 par value per share ("Common Stock"), of Issuer at a price per share in
cash equal to $34.06 (the "Option Price"); provided, however, that in no event
shall the number of shares for which the Option is exercisable exceed 19.9% of
the shares of Common Stock issued and outstanding at the time of exercise
(without giving effect to the shares of Common Stock issued or issuable under
the Option) (the "Maximum Applicable Percentage"). The number of shares of
Common Stock purchasable upon exercise of the Option and the Option Price are
subject to adjustment as set forth in this Agreement.

     (b) In the event that any additional shares of Common Stock are issued or
otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement), the aggregate number of shares of Common Stock
purchasable upon exercise of the Option (inclusive of shares, if any, previously
purchased upon exercise of the Option) shall automatically be increased (without
any further action on the part of Issuer or Grantee being necessary) so that,
after such issuance, it equals the Maximum Applicable Percentage. Any such
increase shall not affect the Option Price.

     2. Exercise; Closing. (a) Conditions to Exercise; Termination. Grantee
(sometimes referred to as the "Holder") may exercise the Option, in whole or in
part, by delivering a written notice thereof as provided in Section 2(d) within
135 days following the occurrence of a Triggering Event (as defined in Section
2(b)) unless prior to such Triggering Event the Effective Time (as defined in
the Merger Agreement) shall have occurred or the Option shall have terminated in
accordance with the following sentence. If no notice pursuant to the preceding
sentence has been delivered prior thereto, the Option shall terminate upon
either (i) the occurrence of the Effective Time or (ii) the close of business on
the earlier of (x) the day 135 days after the date that Grantee becomes entitled
to receive the Termination Fee (as defined in the Merger Agreement) under
Section 8.5(b) of the Merger Agreement and (y) the date that

                                      A-45
<PAGE>   118

Grantee is no longer potentially entitled to receive the Termination Fee under
Section 8.5(b) of the Merger Agreement for a reason other than that Grantee has
already received the Termination Fee.

     (b) Triggering Event. A "Triggering Event" shall have occurred if the
Merger Agreement is terminated and Grantee shall have become entitled to receive
the Termination Fee pursuant to Section 8.5(b) of the Merger Agreement.

     (c) Notice of Triggering Event by Issuer. Issuer shall notify Grantee
promptly in writing of the occurrence of any Triggering Event, it being
understood that the giving of such notice by Issuer shall not be a condition to
the right of the Holder to exercise the Option.

     (d) Notice of Exercise by Grantee. If the Holder shall be entitled to and
wishes to exercise the Option, it shall send to Issuer a written notice (the
date of which is referred to in this Agreement as the "Notice Date") specifying
(i) the total number of shares that the Holder will purchase pursuant to such
exercise and (ii) a place and date (a "Closing Date") not earlier than three
business days nor later than 20 business days from the Notice Date for the
closing of such purchase (a "Closing"); provided, that if the Closing cannot be
effected by reason of the application of any laws, (x) the Holder or Issuer, as
required, promptly after the giving of such notice shall file the required
notice, report, filing or application for approval and shall expeditiously
process the same and (y) the Closing Date shall be extended to not later than
the tenth business day following the expiration or termination of the
restriction imposed by such law. Each of the Holder and the Issuer agrees to use
its reasonable best efforts to cooperate with and provide information to Issuer
or Holder, as the case may be, for the purpose of any required notice, report,
filing or application for approval.

     (e) Payment of Purchase Price. At each Closing, the Holder shall pay to
Issuer the aggregate purchase price for the shares of Common Stock purchased
pursuant to the exercise of the Option in immediately available funds by a wire
transfer to a bank account designated by Issuer; provided, that failure or
refusal of Issuer to designate such a bank account shall not preclude the Holder
from exercising the Option, in whole or in part.

     (f) Delivery of Common Stock. At such Closing, simultaneously with the
payment of the purchase price by the Holder, Issuer shall deliver to the Holder
a certificate or certificates representing the number of shares of Common Stock
purchased by the Holder and, if the Option shall be exercised in part only, a
new Option evidencing the rights of the Holder to purchase the balance (as
adjusted pursuant to Section 1(b)) of the shares of Common Stock then
purchasable under this Agreement and the Holder shall deliver to the Company its
written agreement that the Holder will not offer to sell or otherwise dispose of
such shares of Common Stock in violation of law or this Agreement.

     (g) Restrictive Legend. Certificates for Common Stock delivered at a
Closing shall be endorsed with a restrictive legend that shall read
substantially as follows:

          "The transfer of the shares represented by this certificate is subject
     to resale restrictions arising under the Securities Act of 1933, as
     amended, and pursuant to the terms of a Stock Option Agreement dated as of
     September 9, 1999. A copy of such agreement will be provided to the holder
     hereof without charge upon receipt by the Company of a written request
     therefor."

It is understood and agreed that the above legend shall be removed, insofar as
it refers to the Securities Act of 1933, by delivery of substitute
certificate(s) without such reference to the Securities Act of 1933 if the
Holder shall have delivered to Issuer a copy of a letter from the staff of the
Securities and Exchange Commission, or a written opinion of counsel, in form and
substance reasonably satisfactory to Issuer, to the effect that such reference
is not required for purposes of the Securities Act of 1933, as amended (the
"Securities Act"). In addition, such certificates shall bear any other legend as
may be required by applicable law.

                                      A-46
<PAGE>   119

     3. Covenants of Issuer. In addition to its other agreements and covenants
in this Agreement, Issuer agrees:

          (a) Shares Reserved for Issuance. It will maintain, free from
     preemptive rights, sufficient authorized but unissued or treasury shares of
     Common Stock to issue the appropriate number of shares of Common Stock
     pursuant to the terms of this Agreement so that the Option may be fully
     exercised without additional authorization of Common Stock after giving
     effect to all other options, warrants, convertible securities and other
     rights of third parties to purchase shares of Common Stock from Issuer.

          (b) No Avoidance. It will not avoid or seek to avoid (whether by
     charter amendment or through reorganization, consolidation, merger,
     issuance of rights, dissolution or sale of assets, or by any other
     voluntary act) the observance or performance of any of the covenants,
     agreements or conditions to be observed or performed under this Agreement
     by Issuer.

          (c) Further Assurances. After the date of this Agreement, it will
     promptly take all actions as may from time to time be required (including
     (i) complying with all applicable premerger notification, reporting and
     waiting period requirements under the Hart-Scott-Rodino Antitrust
     Improvements Act of 1976, as amended and (ii) in the event that prior
     notice, report, filing or approval with respect to any Governmental Entity
     is necessary under any applicable foreign or United States federal, state
     or local law before the Option may be exercised, cooperating fully with the
     Holder in preparing and processing the required applications or notices) in
     order to permit each Holder to exercise the Option and purchase shares of
     Common Stock pursuant to such exercise subject to the terms and conditions
     hereof.

          (d) Stock Exchange Listing. It will use its reasonable best efforts to
     cause the shares of Common Stock to be issued pursuant to the Option to be
     approved for listing (to the extent they are not already listed) on the New
     York Stock Exchange ("NYSE"), if the Common Stock is then listed on the
     NYSE, and on all other stock exchanges on which shares of Common Stock of
     the Issuer are then listed, subject to official notice of issuance.

     4. Representations and Warranties of Issuer. Issuer represents and warrants
to Grantee as follows:

          (a) Merger Agreement. Issuer hereby makes each of the representations
     and warranties contained in Section 5.1(a), (b), (c), (d), (j) and (s) of
     the Merger Agreement to the extent they relate to Issuer and this
     Agreement, as if such representations were set forth in this Agreement.

          (b) Shares Reserved for Issuance; Capital Stock. Issuer has taken all
     necessary corporate action to authorize and reserve, free from preemptive
     rights, and permit it to issue, sufficient authorized but unissued or
     treasury shares of Common Stock so that the Option may be fully exercised
     without additional authorization of Common Stock after giving effect to all
     other options, warrants, convertible securities and other rights of third
     parties to purchase shares of Common Stock from Issuer, and all such
     shares, upon issuance pursuant to the Option, will be duly authorized,
     validly issued, fully paid and nonassessable, and will be delivered free
     and clear of all claims, liens, encumbrances, and security interests (other
     than those created by this Agreement) and not subject to any preemptive
     rights.

     5. Representations and Warranties of Grantee. Grantee hereby makes each of
the representations and warranties contained in Section 5.2(a), (c) and (d) of
the Merger Agreement to the extent they relate to the Grantee and this
Agreement, as if such representations were set forth in this Agreement.

     6. Exchange; Replacement. This Agreement and the Option granted by this
Agreement are exchangeable, without expense, at the option of the Holder, upon
presentation and surrender of this Agreement at the principal office of Issuer,
for other Agreements providing for Options of different denominations entitling
the holder thereof to purchase in the aggregate the same number of shares of
Common Stock purchasable at such time under this Agreement, subject to
corresponding adjustments in the number of shares of Common Stock purchasable
upon exercise so that the aggregate number of such shares under all stock option
agreements issued in respect of this Agreement shall not exceed the

                                      A-47
<PAGE>   120

Maximum Applicable Percentage. Unless the context shall require otherwise, the
terms "Agreement" and "Option" as used in this Agreement include any stock
option agreements and related Options for which this Agreement (and the Option
granted by this Agreement) may be exchanged. Upon (i) receipt by Issuer of
evidence reasonably satisfactory to it of the loss, theft, destruction of this
Agreement, or mutilation of this Agreement, (ii) receipt by Issuer of reasonably
satisfactory indemnification in the case of loss, theft or destruction of this
Agreement and (iii) surrender and cancellation of this Agreement in the case of
mutilation, Issuer will execute and deliver a new Agreement of like tenor and
date.

     7. Adjustments. In addition to the adjustment to the total number of shares
of Common Stock purchasable upon exercise of the Option pursuant to Section
1(b), the total number of shares of Common Stock purchasable upon the exercise
of the Option and the Option Price shall be subject to adjustment from time to
time as follows:

          In the event of any change in the outstanding shares of Common Stock
     by reason of stock dividends, split-ups, mergers, recapitalizations,
     combinations, subdivisions, conversions, exchanges of shares or the like,
     the type and number of shares of Common Stock purchasable upon exercise of
     the Option, and the Option Price therefor, shall be appropriately adjusted,
     and proper provision shall be made in the agreements governing any such
     transaction, so that (i) any Holder shall receive upon exercise of the
     Option the number and class of shares, other securities, property or cash
     that such Holder would have received in respect of the shares of Common
     Stock purchasable upon exercise of the Option if the Option had been
     exercised and such shares of Common Stock had been issued to such Holder
     immediately prior to such event or the record date therefor, as applicable,
     and (ii) in the event any additional shares of Common Stock are to be
     issued or otherwise become outstanding as a result of any such change
     (other than pursuant to an exercise of the Option), the number of shares of
     Common Stock purchasable upon exercise of the Option shall be increased so
     that, after such issuance and together with shares of Common Stock
     previously issued pursuant to the exercise of the Option (as adjusted on
     account of any of the foregoing changes in the Common Stock), the number of
     shares so purchasable equals the Maximum Applicable Percentage of the
     number of shares of Common Stock issued and outstanding immediately after
     the consummation of such change.

     8. Registration. (a) Upon the occurrence of a Triggering Event, Issuer
shall, at the request of Grantee delivered in the written notice of exercise of
the Option provided for in Section 2(d), as promptly as practicable prepare,
file and keep current a shelf registration statement under the Securities Act
covering any or all shares issued and issuable pursuant to the Option and shall
use its reasonable best efforts to cause such registration statement to become
and remain effective for such period not in excess of 180 days from the day such
registration statement first becomes effective as may be reasonably necessary to
permit the sale or other disposition of any shares of Common Stock issued upon
total or partial exercise of the Option ("Option Shares") in accordance with any
plan of disposition requested by Grantee; provided, however, that Issuer may
suspend filing of or maintaining the effectiveness of a registration statement
relating to a registration request by Grantee under this Section 8 for a period
of time (not in excess of 60 days in the aggregate) if in its judgment such
filing of such registration statement or the maintenance of its effectiveness
would require the disclosure of nonpublic information that Issuer has a good
faith business purpose for preserving as confidential. Subject to the foregoing,
Issuer will use its reasonable best efforts to cause such registration statement
to become effective as soon as practicable. In connection with any such
registration, Issuer and Grantee shall provide each other with representations,
warranties, indemnities and other agreements customarily given in connection
with such registrations. If requested by Grantee in connection with such
registration, Issuer shall become a party to any underwriting agreement relating
to the sale of such shares, but only to the extent of obligating Issuer in
respect of representations, warranties, indemnities, contribution and other
agreements customarily made by issuers in such underwriting agreements.

     (b) To the extent consistent with the other provisions hereof, in the event
that Grantee so requests, the closing of the sale or other disposition of the
Common Stock or other securities pursuant to a registration statement filed
pursuant to Section 8(a) shall occur substantially simultaneously with the
exercise of the Option.
                                      A-48
<PAGE>   121

     (c) Notwithstanding any other provision hereof, any request for
registration shall permit the Issuer, upon written notice given within 30 days
of the request for registration, to repurchase from the Grantee any shares as to
which the Grantee requests registration at a price per share equal to the
average of the closing price per share of Common Stock on the NYSE as reported
in the Wall Street Journal, New York City edition, on the twenty NYSE trading
days ending on the second business day prior to the date Issuer notifies the
Grantee of its decision to so repurchase.

     9. Repurchase of Option and/or Shares. (a) Repurchase; Repurchase
Price. Upon the occurrence of a Triggering Event, (i) at the request of a
Holder, delivered in writing within 135 days of such occurrence (or such later
period as provided in Section 2(d) with respect to any required notice or
application or in Section 12), Issuer shall repurchase the Option from the
Holder, in whole or in part, at a price (the "Option Repurchase Price") equal to
the number of shares of Common Stock then purchasable upon exercise of the
Option (or such lesser number of shares as may be designated in the repurchase
notice) multiplied by the amount by which the market/offer price (as defined
below) exceeds the Option Price and (ii) at the request of a Holder, delivered
in writing within 135 days of such occurrence (or such later period as provided
in Section 2(d) with respect to any required notice or application or in Section
12), Issuer shall repurchase such number of Option Shares from such Holder as
the Holder shall designate in the Repurchase Notice at a price (the "Option
Share Repurchase Price") equal to the number of shares designated multiplied by
the market/offer price. The term "market/offer price" shall mean the highest of
(x) the price per share of Common Stock at which a tender or exchange offer for
Common Stock has been made during the term of the Option, (y) the price per
share of Common Stock to be paid by any third party pursuant to an agreement
with Issuer with respect to a Business Combination Transaction (defined below)
and (z) the highest trading price for shares of Common Stock on the NYSE (or, if
the Common Stock is not then listed on the NYSE, any other national securities
exchange or automated quotation system on which the Common Stock is then listed
or quoted) within the six-month period immediately preceding the delivery of the
repurchase notice. In the event that a tender or exchange offer is made for the
Common Stock or an agreement is entered into for a merger, share exchange,
consolidation or reorganization involving consideration other than cash, the
value of the securities or other property issuable or deliverable in exchange
for the Common Stock shall (I) if such consideration is in securities and such
securities are listed on a national securities exchange, be determined to be the
highest trading price for such securities on such national securities exchange
within the six month period immediately preceding the delivery of the repurchase
notice or (II) if such consideration is not securities, or if in securities and
such securities are not traded on a national securities exchange, be determined
in good faith by a nationally recognized investment banking firm selected by an
investment banking firm designated by Grantee and an investment banking firm
designated by Issuer. "Business Combination Transaction" shall mean (i) a
consolidation, exchange of shares or merger of Issuer with any Person, other
than the Grantee or one of its subsidiaries, and, in the case of a merger, in
which Issuer shall not be the continuing or surviving corporation, (ii) a merger
of Issuer with a Person, other than the Grantee or one of its Subsidiaries, in
which Issuer shall be the continuing or surviving corporation but the then
outstanding shares of Common Stock shall be changed into or exchanged for stock
or other securities of Issuer or any other Person or cash or any other property
or the shares of Common Stock outstanding immediately before such merger shall
after such merger represent less than 50% of the common shares and common share
equivalents of Issuer outstanding immediately after the merger or (iii) a sale,
lease or other transfer of all or substantially all the assets of Issuer to any
Person, other than the Grantee or one of its Subsidiaries.

     (b) Method of Repurchase. A Holder may exercise its right to require Issuer
to repurchase the Option, in whole or in part, and/or any Option Shares then
owned by such Holder pursuant to this Section 9 by surrendering for such purpose
to Issuer, at its principal office, this Agreement or certificates for Option
Shares, as applicable, accompanied by a written notice or notices stating that
the Holder elects to require Issuer to repurchase the Option and/or such Option
Shares in accordance with the provisions of this Section 9. As promptly as
practicable, and in any event within three business days after the surrender of
the Option and/or certificates representing Option Shares and the receipt of the
repurchase notice relating thereto, Issuer shall deliver or cause to be
delivered to the Holder the applicable Option
                                      A-49
<PAGE>   122

Repurchase Price and/or the Option Share Repurchase Price subject to receipt by
Issuer of a certificate executed by the Holder containing representations and
warranties that, immediately prior to the repurchase thereof pursuant to this
Section 9, the Holder had sole record and beneficial ownership of the Option or
the Option Shares, or both, as the case may be, and that, other than pursuant to
this Agreement, the Option or the Option Shares, or both, as the case may be,
were held free and clear of all material liens. Any Holder shall have the right
to require that the repurchase of Option Shares shall occur immediately after
the exercise of all or part of the Option. In the event that the repurchase
notice shall request the repurchase of the Option in part, Issuer shall deliver
with the Option Repurchase Price a new Stock Option Agreement evidencing the
right of the Holder to purchase that number of shares of Common Stock
purchasable pursuant to the Option at the time of delivery of the repurchase
notice minus the number of shares of Common Stock represented by that portion of
the Option then being repurchased.

     (c) Effect of Statutory or Regulatory Restraints on Repurchase. To the
extent that, upon or following the delivery of a repurchase notice, Issuer is
prohibited under applicable law or regulation from repurchasing the Option (or
portion thereof) and/or any Option Shares subject to such repurchase notice (and
Issuer will undertake to use its reasonable best efforts to obtain all required
regulatory and legal approvals and to file any required notices as promptly as
practicable in order to accomplish such repurchase), Issuer shall immediately so
notify the Holder in writing and thereafter deliver or cause to be delivered,
from time to time, to the Holder the portion of the Option Repurchase Price and
the Option Share Repurchase Price that Issuer is no longer prohibited from
delivering, within two business days after the date on which it is no longer so
prohibited; provided, however, that upon notification by Issuer in writing of
such prohibition, the Holder may, within five days of receipt of such
notification from Issuer, revoke in writing its repurchase notice, whether in
whole or to the extent of the prohibition, whereupon, in the latter case, Issuer
shall promptly (i) deliver to the Holder that portion of the Option Repurchase
Price and/or the Option Share Repurchase Price that Issuer is not prohibited
from delivering; and (ii) deliver to the Holder, as appropriate, (A) with
respect to the Option, a new Stock Option Agreement evidencing the right of the
Holder to purchase that number of shares of Common Stock for which the
surrendered Stock Option Agreement was exercisable at the time of delivery of
the Repurchase Notice less the number of shares as to which the Option
Repurchase Price has theretofore been delivered to the Holder, and/or (B) with
respect to Option Shares, a certificate for the Option Shares as to which the
Option Share Repurchase Price has not theretofore been delivered to the Holder.
Notwithstanding anything to the contrary in this Agreement, including, without
limitation, the time limitations on the exercise of the Option, the Holder may
give notice of exercise of the Option for 135 days after a notice of revocation
has been issued pursuant to this Section 9(c) and thereafter exercise the Option
in accordance with the applicable provisions of this Agreement.

     (d) Acquisition Transactions. In addition to any other restrictions or
covenants, Issuer agrees that, in the event that a Holder delivers a repurchase
notice, Issuer shall not enter or agree to enter into an agreement or series of
agreements relating to a merger with or into or the consolidation with any other
person or entity, the sale of all or substantially all of the assets of Issuer
or any similar disposition unless the other party or parties to such agreement
or agreements agree to assume in writing Issuer's obligations under Section 9(a)
and, notwithstanding any notice of revocation delivered pursuant to the proviso
to Section 9(c), a Holder may require such other party or parties to perform
Issuer's obligations under Section 9(a) unless such party or parties are
prohibited by law or regulation from such performance, in which case such party
or parties shall be subject to the obligations of the Issuer under Section 9(c).

     10. Repurchase at the Option of the Company.

          (a) To the extent the Grantee shall not have previously exercised its
     rights under Section 9, at the written request of Issuer made at any time
     during the 135-day period commencing at the expiration of the 135-day
     periods for exercise of rights under Section 9 (the "Call Period"), Issuer
     may repurchase from the Holder, and the Holder shall sell, or cause to be
     sold to Issuer, three-quarters (but not less than three-quarters) of the
     shares of Common Stock acquired by the Holder pursuant hereto and with
     respect to which the Holder has ownership at the time of such repurchase at
     a price per share equal to the greater of (A) the market/offer price (as
     defined in Section 9, except
                                      A-50
<PAGE>   123

     all references to any repurchase notice shall instead be to the written
     request made by Issuer pursuant to this Section 10(a)) and (B) the Option
     Price per share in respect of the shares so acquired (the higher of such
     per share prices in (A) and (B) multiplied by the number of shares of
     Common Stock to be repurchased pursuant to this Section 10 being herein
     called the "Call Consideration"). The date on which the Company exercises
     its rights under this Section 10 is referred to as the "Call Date."

          (b) If the Company exercises its rights under this Section 10, Issuer
     shall, within three business days pay the Call Consideration in immediately
     available funds and the Holder shall surrender to Issuer certificates
     evidencing the shares of Common Stock purchased hereunder, and the Holder
     shall warrant to Issuer that, immediately prior to the repurchase thereof
     pursuant to this Section 10, the Holder had sole record and beneficial
     ownership of such shares and that such shares were then held free and clear
     of all material liens.

          (c) To the extent that the Holder shall exercise the Option, the
     Holder shall, unless the Holder shall exercise its rights under Section 9
     to cause the repurchase of the Option Shares, or Issuer shall exercise its
     rights to repurchase the Option Shares under this Section 10, retain sole
     ownership of the Option Shares acquired through the end of the Call Period.

     11. First Refusal. Subject to the provisions of Sections 9 and 10 herein,
at any time after the first occurrence of a Triggering Event and prior to the
second anniversary of the first purchase of shares of Common Stock pursuant to
the Option, if the Holder shall desire to sell, assign, transfer or otherwise
dispose of all or any of the Option Shares or other securities acquired by it
pursuant to the Option, it shall give Issuer written notice of the proposed
transaction (an "Offeror's Notice"), identifying the proposed transferee,
accompanied by a copy of a binding offer to purchase such shares or other
securities signed by such transferee and setting forth the terms of the proposed
transaction. An Offeror's Notice shall be deemed an offer by the Holder to
Issuer, which may be accepted, in whole but not in part, within 20 business days
of the receipt of such Offeror's Notice, on the same terms and conditions and at
the same price at which Issuer is proposing to transfer such shares or other
securities to such transferee. The purchase of any such shares or other
securities by Issuer shall be settled within 20 business days of the date of the
acceptance of the offer and the purchase price shall be paid to the Holder in
immediately available funds. If Issuer shall fail or refuse to purchase all the
shares or other securities covered by an Offeror's Notice, the Holder may,
within 60 days from the date of the Offeror's Notice, sell all, but not less
than all, of such shares or other securities to the proposed transferee at no
less than the price specified and on terms no more favorable than those set
forth in the Offeror's Notice; provided, however, that the provisions of this
sentence shall not limit the rights the Holder may otherwise have if Issuer has
accepted the offer contained in the Offeror's Notice and wrongfully refuses to
purchase the shares or other securities subject thereto. The requirements of
this Section 11 shall not apply to (a) any disposition as a result of which the
proposed transferee would own beneficially not more than 2% of the outstanding
voting power of Issuer, (b) any disposition of Common Stock or other securities
by a Person to whom the Holder has assigned its rights under the Option with the
consent of Issuer, (c) any sale by means of a public offering registered under
the Securities Act or (d) any transfer to a wholly owned subsidiary of the
Holder which agrees in writing to be bound by the terms hereof.

     12. Extension of Exercise Periods. The 135-day periods for exercise of
certain rights under Sections 2 and 9 shall be extended in each such case at the
request of the Holder to the extent necessary to avoid liability by the Holder
under Section 16(b) of the Securities Exchange Act of 1934, as amended ("Section
16(b)"), by reason of such exercise. Furthermore, in the event the Company
exercises its rights under Section 10, the Holder may defer the Call Date to the
extent necessary to avoid liability by the Holder under Section 16(b).

     13. Assignment. Neither party may assign any of its rights or obligations
under this Agreement or the Option to any other person without the express
written consent of the other party. Any attempted assignment in contravention of
the preceding sentence shall be null and void.

                                      A-51
<PAGE>   124

     14. Filings; Other Actions. The parties hereto will use their reasonable
best efforts to make all filings with, and to obtain consents of, all third
parties and governmental authorities necessary for the consummation of the
transactions contemplated by this Agreement.

     15. Specific Performance. The parties acknowledge that damages would be an
inadequate remedy for a breach of this Agreement by either party and that the
obligations of the parties shall be specifically enforceable through injunctive
or other equitable relief.

     16. Severability. If any term, provision, covenant, or restriction
contained in this Agreement is held by a court or a federal or state regulatory
agency of competent jurisdiction to be invalid, void, or unenforceable, the
remainder of the terms, provisions, covenants, and restrictions contained in
this Agreement shall remain in full force and effect, and shall in no way be
affected, impaired, or invalidated. If for any reason such court or regulatory
agency determines that the Holder is not permitted to acquire, or Issuer is not
permitted to repurchase pursuant to Sections 9, 10 or 11 the full number of
shares of Common Stock provided in Section 1(a) of this Agreement (as adjusted
pursuant to Sections 1(b) and 7 of this Agreement), it is the express intention
of Issuer to allow the Holder to acquire or to require Issuer to repurchase such
lesser number of shares as may be permissible, without any amendment or
modification of this Agreement.

     17. Notices. Notices, requests, instructions or other documents to be given
under this Agreement shall be in writing and shall be deemed given, (i) when
received, if sent by facsimile, (ii) when delivered, if delivered personally to
the intended recipient, and (iii) one business day later, if sent by overnight
delivery via a national courier service, in each case at the respective
addresses of the parties set forth in the Merger Agreement.

     18. Expenses. Except as otherwise expressly provided in this Agreement or
in the Merger Agreement, all costs and expenses incurred in connection with this
Agreement and the transactions contemplated by this Agreement shall be paid by
the party incurring such expense, including fees and expenses of its own
financial consultants, investment bankers, accountants, and counsel.

     19. Entire Agreement. This Agreement, the Confidentiality Agreement (as
defined in the Merger Agreement) and the Merger Agreement constitute the entire
agreement, and supersede all other prior agreements, understandings,
representations and warranties, both written and oral, between the parties, with
respect to the subject matter of this Agreement. The terms and conditions of
this Agreement shall inure to the benefit of and be binding upon the parties and
their respective successors and permitted assigns. Nothing in this Agreement is
intended to confer upon any person or entity, other than the parties to this
Agreement, and their respective successors and permitted assigns, any rights or
remedies under this Agreement.

     20. Governing Law and Venue; Waiver of Jury Trial.

          (a) This Agreement shall be deemed to be made in and in all respects
     shall be interpreted, construed and governed by and in accordance with
     Delaware law without regard to the conflict of law principles thereof. The
     parties irrevocably and unconditionally consent to submit to the exclusive
     jurisdiction of the courts of the State of Delaware and of the United
     States of America located in Wilmington, Delaware (the "Delaware Courts")
     for any litigation arising out of or relating to this Agreement and the
     transactions contemplated by this Agreement (and agree not to commence any
     litigation relating thereto except in such Delaware Courts), waive any
     objection to the laying of venue of any such litigation in the Delaware
     Courts and agree not to plead or claim in any Delaware Court that such
     litigation brought therein has been brought in an inconvenient forum.

          (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
     ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT
     ISSUES, AND THEREFORE EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY
     WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
     LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
     AGREEMENT, OR THE TRANSACTIONS
                                      A-52
<PAGE>   125

     CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT
     (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS
     REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN THE
     EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY
     UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH
     PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH PARTY HAS BEEN INDUCED
     TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
     CERTIFICATIONS IN THIS SECTION 20.

     21. Captions. The Section and paragraph captions in this Agreement are for
convenience of reference only, do not constitute part of this Agreement and
shall not be deemed to limit or otherwise affect any of the provisions of this
Agreement.

     22. Limitation on Profit. (a) Notwithstanding any other provisions of this
Agreement including, without limitation, Sections 8, 9, 10 and 11 hereof, in no
event shall the Grantee's Total Profit (as defined herein) exceed in the
aggregate $30 million (the "Maximum Amount") and, if it otherwise would exceed
such amount, the Grantee, at its sole election, shall either: (i) reduce the
number of shares of Common Stock subject to this Option; (ii) deliver to the
Issuer for cancellation Option Shares previously purchased by Grantee; (iii) pay
cash to the Issuer; or (iv) any combination thereof, so that Grantee's Total
Profit shall not exceed the Maximum Amount taking into account the foregoing
actions.

     (b) Notwithstanding any other provision of this Agreement, this Option may
not be exercised for a number of shares as would, as of the date of exercise,
result in a Notional Total Profit (as defined below) which would exceed the
Maximum Amount; provided, that nothing in this sentence shall restrict any
exercise of the Option permitted hereby on any subsequent date if such exercise
would not then be restricted by this Section 22(b).

     (c) As used in this Agreement, the "Total Profit" shall mean the aggregate
amount (before taxes) of the following: (i)(x) the amount received by Grantee or
concurrently being paid to Grantee pursuant to Issuer's repurchase of the Option
(or any portion thereof) or any Option Shares pursuant to Sections 9, 10 or 11
less, in the case of any repurchase of Option Shares, (y) the Grantee's purchase
price for such Option Shares, as the case may be and (ii)(x) the amounts
received by Grantee or concurrently being paid to Grantee pursuant to the sale
of Option Shares (or any other securities into which such Option Shares are
converted or exchanged) to the Issuer or any other Person (as defined in the
Merger Agreement) including sales made pursuant to a registration statement or
an exemption therefrom, less (y) the Grantee's purchase price for such Option
Shares.

     (d) As used in this Agreement, the term "Notional Total Profit" with
respect to any number of shares as to which Grantee may propose to exercise the
Option shall be the Total Profit determined as of the date of such proposal
assuming that the Option were exercised on such date for such number of shares
and assuming that such shares, together with all other Option Shares held by
Grantee and its affiliates as of such date, were sold for cash at the closing
market price for the Common Stock as of the close of business on the preceding
trading day (less customary brokerage commissions) and including all amounts
theretofore received or concurrently being paid to Grantee pursuant to clauses
(i) and (ii) of the definition of Total Profit.

                                 EXHIBIT 6.7(A)

                     FORM OF COMPANY STOCKHOLDER AGREEMENT

     This STOCKHOLDER AGREEMENT, dated as of             , 1999 (this
"Agreement") is between Illinois Tool Works Inc., a Delaware corporation
("Parent"), and the undersigned stockholder ("Stockholder") of Premark
International, Inc., a Delaware corporation (the "Company"). Capitalized terms
not otherwise defined in this Agreement have the meanings ascribed to them in
the Merger Agreement (as defined below).

                                    RECITALS

     A. Parent and the Company have entered into an Agreement and Plan of
Merger, dated as of September 9, 1999 (the "Merger Agreement"), pursuant to
which CS Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary
of Parent ("Merger Sub"), will merge with and into the Company (the "Merger"),
with the Company surviving the Merger and becoming a wholly owned subsidiary of
Parent;

     B. Pursuant to the Merger Agreement, at the Effective Time, outstanding
shares of Company Common Stock, including any Company Common Stock owned by
Stockholder, will be converted into the right to receive shares of Parent Common
Stock;

     C. It is a condition to each party's obligation to effect the Merger that
(i) legal counsel to the Company and Parent shall have delivered their
respective opinions to the effect that the Merger will constitute a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), and Parent, Merger Sub and the Company each
will be a party to the reorganization within the meaning of Section 368(b) of
the Code, (ii) Parent shall have received a letter from its independent public
accounting firm to the effect that the Merger should qualify for "pooling-of-
interests" accounting treatment and (iii) the Company shall have received a
letter from its independent public accounting firm to the effect that the
Company is a poolable entity;

     D. The execution and delivery of this Agreement by Stockholder is a
material inducement to Parent and the Company to enter into the Merger
Agreement; and

     E. Stockholder has been advised that Stockholder may be deemed to be an
"affiliate" of the Company, as such term is used (i) for purposes of paragraphs
(c) and (d) of Rule 145 of the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Act"), or (ii)
in the Commission's Accounting Series Releases 130 and 135, as amended, although
nothing contained herein shall be construed as an admission by Stockholder that
Stockholder is in fact an affiliate of the Company.

     NOW, THEREFORE, intending to be legally bound, the parties agree as
follows:

     1. Acknowledgments by Stockholder. Stockholder acknowledges and understands
that the representations, warranties and covenants made by Stockholder set forth
in this Agreement will be relied upon by Parent, the Company and their
respective affiliates, counsel and accounting firms, and that substantial losses
and damages may be incurred by such persons if Stockholder's representations,
warranties or covenants are breached. Stockholder has carefully read this
Agreement and the Merger Agreement and has consulted with such legal counsel and
financial advisers as Stockholder has deemed appropriate in connection with the
execution of this Agreement.

     2. Compliance with Rule 145 and the Act.

          (a) Stockholder has been advised that (i) the issuance of shares of
     Parent Common Stock in connection with the Merger is expected to be
     effected pursuant to a Registration Statement filed by Parent on Form S-4,
     and the resale of such shares will be subject to the restrictions set forth
     in Rule 145 under the Act unless such shares are otherwise transferred
     pursuant to an effective registration statement under the Act or an
     appropriate exemption from registration, and
                                      A-55
<PAGE>   128

     (ii) Stockholder may be deemed to be an affiliate of the Company, although
     nothing contained herein shall be construed as an admission by Stockholder
     that Stockholder is an affiliate of the Company. Stockholder agrees not to
     sell, pledge, transfer or otherwise dispose of any shares of Parent Common
     Stock issued to Stockholder in the Merger unless (i) such sale, pledge,
     transfer or other disposition is made in conformity with the requirements
     of Rule 145 under the Act, (ii) such sale, pledge, transfer or other
     disposition is made pursuant to an effective registration statement under
     the Act, or (iii) Stockholder delivers to Parent a written opinion of
     counsel, in form and substance reasonably acceptable to Parent, or a
     "no-action" letter obtained from the staff of the Commission, to the effect
     that such sale, pledge, transfer or other disposition is otherwise exempt
     from registration under the Act.

          (b) Parent will give stop transfer instructions to its transfer agent
     with respect to any Parent Common Stock received by Stockholder pursuant to
     the Merger, and there will be placed on the certificates representing such
     Parent Common Stock, or any substitutions therefor, legends stating in
     substance:

             "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED PURSUANT TO
        A BUSINESS COMBINATION WHICH IS BEING ACCOUNTED FOR AS A POOLING OF
        INTERESTS, IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE
        SECURITIES ACT OF 1933 APPLIES, AND MAY ONLY BE TRANSFERRED IN
        CONFORMITY WITH RULE 145, PURSUANT TO AN EFFECTIVE REGISTRATION
        STATEMENT, OR IN ACCORDANCE WITH A WRITTEN OPINION OF COUNSEL,
        REASONABLY ACCEPTABLE TO THE ISSUER, IN FORM AND SUBSTANCE TO THE EFFECT
        THAT SUCH TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT
        OF 1933. SUCH SHARES MAY NOT BE TRANSFERRED UNTIL SUCH TIME AS PARENT
        SHALL HAVE PUBLISHED FINANCIAL RESULTS COVERING AT LEAST 30 DAYS OF
        COMBINED OPERATIONS FOLLOWING THE MERGER WITH THE COMPANY."

        and

             "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED,
        SOLD, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE
        WITH THE REQUIREMENTS OF THE CONDITIONS SPECIFIED IN THE STOCKHOLDER
        AGREEMENT DATED AS OF             , 1999 BETWEEN THE HOLDER OF THIS
        CERTIFICATE AND PARENT, A COPY OF WHICH AGREEMENT MAY BE INSPECTED BY
        THE HOLDER OF THIS CERTIFICATE AT THE PRINCIPAL OFFICES OF PARENT OR
        FURNISHED BY PARENT TO THE HOLDER OF THIS CERTIFICATE UPON WRITTEN
        REQUEST AND WITHOUT CHARGE."

The legends set forth above shall be removed (by delivery of a substitute
certificate without such legends), and Parent shall promptly so instruct its
transfer agent, if a registration statement respecting the sale of the shares
has been declared effective under the Act or if Parent is provided (i)
satisfactory written evidence that the shares have been sold in compliance with
Rule 145 (in which case, the substitute certificate will be issued in the name
of the transferee), (ii) an opinion of counsel, in form and substance reasonably
acceptable to Parent, or (iii) a "no-action" letter obtained from the staff of
the Commission to the effect that sale of the shares by the holder thereof is no
longer subject to Rule 145 or Stockholder was not at the time of the Merger an
affiliate of the Company.

     3. Covenants Related to Pooling of Interests.

          (a) During the period beginning on the date 30 days prior to the
     Closing Date (as defined in the Merger Agreement) and ending on the day
     after Parent has published (within the meaning of Section 201.01 of the
     Commission's Codification of Financial Reporting Policies) financial
     results covering at least 30 days of combined operations following the
     Merger of Parent and the Company
                                      A-56
<PAGE>   129

     (the "Restricted Period"), Stockholder will not sell, exchange, transfer,
     pledge, distribute or otherwise dispose of or grant any option, establish
     any "short" or "put"-equivalent position with respect to or enter into any
     similar transaction (through derivatives or otherwise) intended to have or
     having the effect, directly or indirectly, or reducing its risk relative to
     (i) any shares of Company Common Stock owned by Stockholder or (ii) any
     shares of Parent Common Stock received by Stockholder in connection with
     the Merger. The parties acknowledge that sales of Parent Common Stock
     issuable on exercise of stock options solely to provide for payment of the
     exercise price of such stock options simultaneously with the exercise of
     such stock options shall not constitute such reduction of relative risk.
     The foregoing does not cover withholding taxes, which would constitute a
     reduction of risk.

          (b) Notwithstanding anything to the contrary contained in Section
     3(a), Stockholder will be permitted, during the Restricted Period, (ii) to
     sell, exchange, transfer, pledge, distribute or otherwise dispose of or
     grant any option, establish any "short" or "put"-equivalent position with
     respect to or enter into any similar transaction (through derivatives or
     otherwise) intended to have or having the effect, directly or indirectly,
     of reducing its risk relative to any shares of Company Common Stock or
     Parent Common Stock received by Stockholder in connection with the Merger
     (a "Transfer") equal to the lesser of (A) 10% of the Company Common Stock,
     or equivalent post-Merger Parent Common Stock, owned by Stockholder and (B)
     Stockholder's pro rata portion of 1% of the total number of outstanding
     shares of Company Common Stock, or equivalent post-Merger Parent Common
     Stock, owned by Stockholder and all other stockholders of the Company (in
     each of clause (A) and clause (B) above as measured as of the date of such
     Transfer and subject to confirmation of such calculation by Parent), and
     (ii) to make bona fide charitable contributions or gifts of such
     securities; provided, however, that the transferee(s) of such charitable
     contributions or gifts agree(s) in writing to hold such securities for the
     period specified in Section 3(a).

     4. Miscellaneous.

          (a) This Agreement may be executed in one or more counterparts, each
     of which shall be deemed an original, but all of which together shall
     constitute one and the same document.

          (b) This Agreement shall be enforceable by, and shall inure to the
     benefit of and be binding upon, the parties and their respective successors
     and assigns. As used in this Agreement, the term "successors and assigns"
     means, where the context so permits, heirs, executors, administrators,
     trustees and successor trustees, and personal and other representatives.

          (c) This Agreement shall be deemed to be made in and in all respects
     shall be interpreted, construed and governed by and in accordance with
     Delaware law without regard to the conflict of law principles thereof. The
     parties irrevocably and unconditionally consent to submit to the exclusive
     jurisdiction of the courts of the State of Delaware and of the United
     States of America located in Wilmington, Delaware (the "Delaware Courts")
     for any litigation arising out of or relating to this Agreement and the
     transactions contemplated by this Agreement (and agree not to commence any
     litigation relating thereto except in such Delaware Courts), waive any
     objection to the laying of venue of any such litigation in the Delaware
     Courts and agree not to plead or claim in any Delaware Court that such
     litigation brought therein has been brought in an inconvenient forum.

          (d) If any term, provision, covenant, or restriction contained in this
     Agreement is held by a court or a federal or state regulatory agency of
     competent jurisdiction to be invalid, void, or unenforceable, the remainder
     of the terms, provisions, covenants, and restrictions contained in this
     Agreement shall remain in full force and effect, and shall in no way be
     affected, impaired, or invalidated.

          (e) Counsel to and accountants for the parties to the Merger Agreement
     shall be entitled to rely upon this Agreement as needed.

          (f) This Agreement shall not be modified or amended, or any right
     waived or any obligations excused, except by a written agreement signed by
     both parties.

                                      A-57
<PAGE>   130

          (g) Notwithstanding any other provision contained in this Agreement,
     this Agreement and all obligations under this Agreement shall terminate
     upon the termination of the Merger Agreement in accordance with its terms.

          (h) From and after the Effective Time of the Merger and as long as is
     necessary in order to permit Stockholder to sell Parent Common Stock held
     by Stockholder pursuant to Rule 145 and, to the extent applicable, Rule 144
     under the Act, Parent will file on a timely basis all reports required to
     be filed by it pursuant to the Securities Exchange Act of 1934, as amended,
     and the rules and regulations thereunder, as the same shall be in effect at
     the time, and shall otherwise make available adequate public information
     regarding Parent in such manner as may be required to satisfy the
     requirements of paragraph (c) of Rule 144 under the Act.

     IN WITNESS WHEREOF, this Agreement is executed as of the date first stated
above.

                      FORM OF PARENT STOCKHOLDER AGREEMENT

     This STOCKHOLDER AGREEMENT, dated as of             , 1999 (this
"Agreement"), is by and between Illinois Tool Works Inc., a Delaware corporation
("Parent"), and the undersigned stockholder ("Stockholder") of Parent.
Capitalized terms not otherwise defined in this Agreement have the meanings
ascribed to them in the Merger Agreement (as defined below).

                                    RECITALS

     A. Parent and Premark International, Inc., a Delaware corporation (the
"Company"), have entered into an Agreement and Plan of Merger, dated as of
September 9, 1999 (the "Merger Agreement"), pursuant to which CS Merger Sub
Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger
Sub"), will merge with and into the Company (the "Merger"), with the Company
surviving the Merger and becoming a wholly owned subsidiary of Parent;

     B. It is a condition to the effectiveness of the Merger that (i) legal
counsel to Parent and the Company shall have delivered their respective opinions
to the effect that the Merger will constitute a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code") and Parent, Merger Sub and the Company each will be a party to the
reorganization within the meaning of Section 368(b) of the Code, (ii) Parent
shall have received a letter from its independent public accounting firm to the
effect that the Merger should qualify for "pooling-of-interests" accounting
treatment and (iii) the Company shall have received a letter from its
independent public accounting firm to the effect that the Company is a poolable
entity;

     C. The execution and delivery of this Agreement by Stockholder is a
material inducement to Parent and the Company to enter into the Merger
Agreement; and

     D. Stockholder has been advised that Stockholder may be deemed to be an
"affiliate" of Parent, as such term is used in the Commission's Accounting
Series Releases 130 and 135, as amended, although nothing contained herein shall
be construed as an admission by Stockholder that Stockholder is in fact an
affiliate of Parent.

     NOW, THEREFORE, intending to be legally bound, the parties agree as
follows:

     1. Acknowledgments by Stockholder. Stockholder acknowledges and understands
that the representations, warranties and covenants made by Stockholder set forth
in this Agreement will be relied upon by the Company, Parent and their
respective affiliates, counsel and accounting firms, and that substantial losses
and damages may be incurred by such persons if Stockholder's representations,
warranties or covenants are breached. Stockholder has carefully read this
Agreement and the Merger Agreement and has consulted with such legal counsel and
financial advisers as Stockholder has deemed appropriate in connection with the
execution of this Agreement.

     2. Covenants Related to Pooling of Interests.

          (a) During the period beginning on the date 30 days prior to the
     Closing Date (as defined in the Merger Agreement) and ending on the day
     after Parent has published (within the meaning of Section 201.01 of the
     Commission's Codification of Financial Reporting Policies) financial
     results covering at least 30 days of combined operations following the
     Merger of the Company and Parent (the "Restricted Period"), Stockholder
     will not sell, exchange, transfer, pledge, distribute or otherwise dispose
     of or grant any option, establish any "short" or "put"-equivalent position
     with respect to or enter into any similar transaction (through derivatives
     or otherwise) intended to have or having the effect, directly or
     indirectly, of reducing its risk relative to any shares of Parent Common
     Stock owned by Stockholder. The parties acknowledge that sales of Parent
     Common Stock issuable on exercise of stock options solely to provide for
     payment of the exercise price of such stock options simultaneously with the
     exercise of such stock options shall not constitute such reduction of
     relative risk.

<PAGE>   132

          (b) Notwithstanding anything to the contrary contained in Section
     2(a), Stockholder will be permitted, during the Restricted Period, (i) to
     sell, exchange, transfer, pledge, distribute or otherwise dispose of or
     grant any option, establish any "short" or "put"-equivalent position with
     respect to or enter into any similar transaction (through derivatives or
     otherwise) intended to have or having the effect, directly or indirectly,
     of reducing its risk relative to any shares of Parent Common Stock owned by
     Stockholder (a "Transfer") equal to the lesser of (A) 10% of the Parent
     Common Stock owned by Stockholder and (B) Stockholder's pro rata portion of
     1% of the total number of outstanding shares of Parent Common Stock owned
     by Stockholder and all other stockholders of Parent (in each of clause (A)
     and clause (B) above as measured as of the date of such Transfer and
     subject to confirmation of such calculation by Parent), and (ii) to make
     bona fide charitable contributions or gifts of such securities; provided,
     however, that the transferee(s) of such charitable contributions or gifts
     agree(s) in writing to hold such securities for the period specified in
     Section 2(a). The foregoing does not cover withholding taxes, which would
     constitute a reduction of risk.

     3. Miscellaneous.

          (a) This Agreement may be executed in one or more counterparts, each
     of which shall be deemed an original, but all of which together shall
     constitute one and the same document.

          (b) This Agreement shall be enforceable by, and shall inure to the
     benefit of and be binding upon, the parties and their respective successors
     and assigns. As used in this Agreement, the term "successors and assigns"
     means, where the context so permits, heirs, executors, administrators,
     trustees and successor trustees, and personal and other representatives.

          (c) This Agreement shall be deemed to be made in and in all respects
     shall be interpreted, construed and governed by and in accordance with
     Delaware law without regard to the conflict of law principles thereof. The
     parties irrevocably and unconditionally consent to submit to the exclusive
     jurisdiction of the courts of the State of Delaware and of the United
     States of America located in Wilmington, Delaware (the "Delaware Courts")

     transactions contemplated by this Agreement (and agree not to commence any
     litigation relating thereto except in such Delaware Courts), waive any
     objection to the laying of venue of any such litigation in the Delaware
     Courts and agree not to plead or claim in any Delaware Court that such
     litigation brought therein has been brought in an inconvenient forum.

          (d) If any term, provision, covenant, or restriction contained in this
     Agreement is held by a court or a federal or state regulatory agency of
     competent jurisdiction to be invalid, void, or unenforceable, the remainder
     of the terms, provisions, covenants, and restrictions contained in this
     Agreement shall remain in full force and effect, and shall in no way be
     affected, impaired, or invalidated.

          (e) Counsel to and accountants for the parties to the Merger Agreement
     shall be entitled to rely upon this Agreement as needed.

          (f) This Agreement shall not be modified or amended, or any right
     waived or any obligation excused, except by a written agreement signed by
     both parties.

     this Agreement and all obligations under this Agreement shall terminate
     upon the termination of the Merger Agreement in accordance with its terms.

                      FORM OF PARENT STOCKHOLDER AGREEMENT

     This STOCKHOLDER AGREEMENT, dated as of             , 1999 (this

meanings ascribed to them in the Merger Agreement (as defined below).

                                    RECITALS

     NOW, THEREFORE, intending to be legally bound, the parties agree as
follows:

     1. Acknowledgments by Stockholder. Stockholder acknowledges and understands
that the representations, warranties and covenants made by Stockholder set forth

     indirectly, of reducing its risk relative to any shares of Parent Common
     Stock owned by Stockholder. The parties acknowledge that sales of Parent

     payment of the exercise price of such stock options simultaneously with the
     exercise of such stock options shall not constitute such reduction of
     relative risk.

<PAGE>   135

          (b) Notwithstanding anything to the contrary contained in Section

     of reducing its risk relative to any shares of Parent Common Stock owned by
     Stockholder (a "Transfer") equal to the lesser of (A) 10% of the Parent
     Common Stock owned by Stockholder and (B) Stockholder's pro rata portion of
     1% of the total number of outstanding shares of Parent Common Stock owned
     by Stockholder and all other stockholders of Parent (in each of clause (A)
     and clause (B) above as measured as of the date of such Transfer and
     subject to confirmation of such calculation by Parent), and (ii) to make
     bona fide charitable contributions or gifts of such securities; provided,

     agree(s) in writing to hold such securities for the period specified in
     Section 2(a). The foregoing does not cover withholding taxes, which would
     constitute a reduction of risk.

          (c) Covenants Related to Voting. The Stockholder agrees that all of
     the shares of Parent Common Stock directly owned by the Stockholder at the
     record date for any meeting of stockholders of Parent called to consider
     and vote to approve the issuance (the "Issuance") of Parent Common Stock in
     the Merger and/or the transactions relating thereto will be voted by the
     Stockholder in favor of the Issuance. In addition, the Stockholder agrees
     to use all reasonable efforts, subject to his fiduciary duties as trustee,
     to cause the trusts as to which he is a trustee to vote the shares of
     Parent Common Stock directly owned by such trusts in favor of the Issuance.

     4. Miscellaneous.

          (a) This Agreement may be executed in one or more counterparts, each
     of which shall be deemed an original, but all of which together shall
     constitute one and the same document.

          (b) This Agreement shall be enforceable by, and shall inure to the
     benefit of and be binding upon, the parties and their respective successors
     and assigns. As used in this Agreement, the term "successors and assigns"
     means, where the context so permits, heirs, executors, administrators,
     trustees and successor trustees, and personal and other representatives.

          (c) This Agreement shall be deemed to be made in and in all respects
     shall be interpreted, construed and governed by and in accordance with
     Delaware law without regard to the conflict of law principles thereof. The
     parties irrevocably and unconditionally consent to submit to the exclusive
     jurisdiction of the courts of the State of Delaware and of the United
     States of America located in Wilmington, Delaware (the "Delaware Courts")
     for any litigation arising out of or relating to this Agreement and the
     transactions contemplated by this Agreement (and agree not to commence any
     litigation relating thereto except in such Delaware Courts), waive any
     objection to the laying of venue of any such litigation in the Delaware
     Courts and agree not to plead or claim in any Delaware Court that such
     litigation brought therein has been brought in an inconvenient forum.

          (d) If any term, provision, covenant, or restriction contained in this
     Agreement is held by a court or a federal or state regulatory agency of
     competent jurisdiction to be invalid, void, or unenforceable, the remainder
     of the terms, provisions, covenants, and restrictions contained in this
     Agreement shall remain in full force and effect, and shall in no way be
     affected, impaired, or invalidated.

          (e) Counsel to and accountants for the parties to the Merger Agreement
     shall be entitled to rely upon this Agreement as needed.

          (f) This Agreement shall not be modified or amended, or any right
     waived or any obligation excused, except by a written agreement signed by
     both parties.

          (g) Notwithstanding any other provision contained in this Agreement,
     this Agreement and all obligations under this Agreement shall terminate
     upon the termination of the Merger Agreement in accordance with its terms.

Deerfield, IL 60015

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view
to the holders of the outstanding shares of Common Stock, par value $1.00 per
share (the "Company Shares"), of Premark International, Inc. (the "Company") of
the Exchange Ratio (as defined below) pursuant to the Agreement and Plan of
Merger, dated as of September 9, 1999, among Illinois Tool Works Inc. ("ITW"),
CS Merger Sub Inc., a wholly owned subsidiary of ITW ("Merger Sub"), and the
Company (the "Agreement"). Pursuant to the Agreement, Merger Sub will be merged
with and into the Company and each outstanding Company Share will be converted
into the right to receive a certain number (the "Exchange Ratio") of shares of
Common Stock, par value 0.01 per share ("ITW Common Stock"), of ITW. The
Exchange Ratio shall be equal to (i) if the Parent Average Price (as defined in
the Agreement) is equal to or greater than $66.33 but less than or equal to
$89.73, the result, calculated to four decimal places, of $55.00 divided by the
Parent Average Price; (ii) if the Parent Average Price is greater than $89.73
but less than $101.44, the result, calculated to four decimal places, of [$55.00
+ (0.3065*(Parent Average Price - $89.73))]/Parent Average Price, (iii) if the
Parent Average Price is less than $66.33 but greater than $54.62, the result,
calculated to four decimal places, of [$55.00 - (0.4146*($66.33 - Parent Average
Price))]/Parent Average Price, (iv) if the Parent Average Price is greater than
or equal to $101.44, 0.5776, (v) if the Parent Average Price is less than or
equal to $54.62, 0.9181.

Goldman, Sachs & Co., as part of its investment banking business, is continually
engaged 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 estate, corporate and other purposes. We are familiar with
the Company, having provided certain investment banking services to the Company
from time to time, including having acted as lead managing underwriter of a
public offering of $150 million aggregate principal amount of 6.875% Notes due
November 15, 2008 of the Company in November 1998 and having acted as its
financial advisor in connection with, and having participated in certain of the
negotiations leading to, the Agreement. Goldman, Sachs & Co. provides a full
range of financial advisory and securities services and, in the course of its
normal trading activities, may from time to time effect transactions and hold
securities, including derivative securities, of the Company or ITW for its own
account and for the accounts of customers.

In connection with this opinion, we have reviewed, among other things: the
Agreement, Annual Reports to Stockholders and Annual Reports on Form 10-K of the
Company and ITW for the five years ended December 1998; certain interim reports
to stockholders and Quarterly Reports on Form 10-Q of the Company and ITW;
certain other communications from the Company and ITW to their respective
stockholders; and certain internal financial analyses and forecasts for the
Company and ITW prepared by

their respective managements. We also have held discussions with members of the
senior management of the Company and ITW regarding the past and current business
operations, financial condition and future prospects of their respective
companies. In addition, we have reviewed the reported price and trading activity
for the Company Shares and the ITW Common Stock, compared certain financial and
stock market information for the Company and ITW with similar information for
certain other companies the securities of which are publicly traded, reviewed
the financial terms of certain recent business combinations in the food
equipment industry specifically and in other industries generally and performed
such other studies and analyses as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial and
other information reviewed by us and have assumed such accuracy and completeness
for purposes of rendering this opinion. As you are aware, ITW has informed us
that ITW has not prepared internal forecasts beyond the current fiscal year.
Accordingly, our review of such information was limited to discussions with
senior managers of ITW regarding the estimates of research analysts for the
company. In addition, we have not made any independent evaluation or appraisal
of the assets and liabilities of ITW or the Company or any of their respective
subsidiaries and we have not been furnished with any such evaluation or
appraisal. We have assumed with your consent that the transaction contemplated
by the Agreement will be accounted for as a pooling-of-interests under generally
accepted accounting principles. We were not requested to solicit, and did not
solicit, interest from other parties with respect to an acquisition of or other
business combination with the Company. Our advisory services and the opinion
expressed herein are provided for the information and assistance of the Board of
Directors of the Company in connection with its consideration of the transaction
contemplated by the Agreement and such opinion does not constitute a
recommendation as to how any holder of Company Shares should vote with respect
to such transaction.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio pursuant to the Agreement is fair from a financial point of view to the
holders of Company Shares.

Very truly yours,

/s/ Goldman, Sachs & Co.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Section 145 of the Delaware General Corporation Law ("DGCL") permits a
Delaware corporation to indemnify directors and officers under certain
circumstances. Illinois Tool Works' restated certificate of incorporation and
by-laws provide that Illinois Tool Works shall, subject to certain limitations,
indemnify its directors and officers against expenses (including attorneys'
fees, judgments, fines and certain settlements) actually and reasonably incurred
by them in connection with any suit or proceeding to which they are a party so
long as they acted in good faith and in a manner reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to a
criminal action or proceeding, so long as they had no reasonable cause to
believe their conduct to have been unlawful.

     Section 102 of the DGCL permits a Delaware corporation to include in its
certificate of incorporation a provision eliminating or limiting a director's
liability to a corporation or its stockholders for monetary damages for breaches
of fiduciary duty. DGCL Section 102 provides, however, that liability for
breaches of the duty of loyalty, acts or omissions not in good faith or
involving intentional misconduct, or knowing violation of the law, and the
unlawful purchase or redemption of stock or payment of unlawful dividends or the
receipt of improper personal benefits cannot be eliminated or limited in this
manner. Illinois Tool Works' restated certificate of incorporation includes a
provision that eliminates, to the fullest extent permitted, director liability
for monetary damages for breaches of fiduciary duty.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

     (a) Exhibits

         See Index to Exhibits which is incorporated by reference in this item.

     (b) Financial Statement Schedules:

         Not Applicable

ITEM 22. UNDERTAKINGS.

     The undersigned Registrant 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 of the Registration Statement) 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 the Registration Statement
        or any material change to such information in the Registration
        Statement;

                                      II-1
<PAGE>   140

             provided, however, that paragraphs q(1)(i) and (1)(ii) do not apply
        if the information required to be included in a post-effective amendment
        by those paragraphs is contained in periodic reports filed by the
        Registrant pursuant to Section 13 or Section 15(d) of the Securities
        Exchange Act of 1934 that are incorporated by reference in the
        Registration Statement;

          (2) That, for the purpose 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;

          (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 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 in the Registration Statement and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering of such securities;

          (5) That, prior to any public reoffering of the securities registered
     under this Registration Statement 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 Securities Act of 1933 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 in the Registration Statement, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering of such securities;

          (7) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Item 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

          (8) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved in a
     transaction that was not the subject of and included in the registration
     statement when it became effective.

     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 provisions described under Item 20 above or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission 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 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.

     Re:      Merger of CS Merger Sub Inc., a wholly owned subsidiary
              of Illinois Tool Works Inc., with and into Premark International,
              Inc.

Ladies and Gentlemen:

         As General Counsel of Illinois Tool Works Inc., a Delaware corporation
(the "Company"), I have participated in the corporate and other proceedings
taken by the Company relating to the merger of CS Merger Sub Inc., a wholly
owned subsidiary of the Company, with and into Premark International, Inc.
("Premark"), with Premark being the surviving corporation (the "Merger"), and
the conversion of each share of Premark common stock, par value $1.00 per share,
issued and outstanding at the effective time of the Merger into common stock,
par value $0.01 per share, of the Company ("ITW Common Stock"). I participated
in the preparation and filing with the Securities and Exchange Commission under
the Securities Act of 1933, as amended, of a registration statement on Form S-4
(the "Registration Statement") relating to the Merger and have examined such
other documents and such legal authorities as I have deemed necessary for
purposes of this opinion.

         Based upon the foregoing, I am of the opinion that the ITW Common Stock
has been duly and validly authorized by all necessary action on the part of the
Company and when issued pursuant to the terms of the Agreement and Plan of
Merger, dated as of September 9, 1999, will be validly issued, fully paid and
non-assessable by the Company.

         I consent to the use of my name in the Registration Statement and to
the filing of this opinion as an exhibit to the Registration Statement.

                                          Very truly yours,

                                          /s/ Stewart S. Hudnut

                                          Illinois Tool Works Inc.

         Re:      Material Federal Income Tax Consequences of the Merger

Dear Ladies and Gentlemen:

         We have acted as counsel to Illinois Tool Works Inc. ("ITW") in
connection with the intended merger (the "Merger") of CS Merger Subsidiary
("Merger Sub"), a wholly owned subsidiary of ITW, with and into Premark
International, Inc. ("Premark") pursuant to the Agreement and Plan of Merger
dated as of September 9, 1999 among ITW, Merger Sub and Premark (the "Merger
Agreement"). You have requested that we provide an opinion regarding the
accuracy of the tax disclosures in the joint proxy statement/ prospectus
included as part of the registration statement on Form S-4 filed with the
Securities and Exchange Commission on this date (the "Proxy Statement /
Prospectus").

         In providing this opinion, we have relied on, and assumed the accuracy
of, (i) the description of the transaction as set forth in the Merger Agreement
and the exhibits thereto, including the representations and covenants of ITW and
Premark contained therein and (ii) the description of the transaction as set
forth in the Proxy Statement/Prospectus and the exhibits thereto.

         Based upon and subject to the foregoing, it is our opinion that the
summaries of federal income tax consequences set forth in the Proxy

exceed two million three hundred thousand (2,300,000) plus the number of Shares
reserved for Stock Option use under the Prior Plans and transferred to this Plan
pursuant to Article 19; provided, however, that if during the term of the Plan
the Company repurchases Shares, additional Options may be granted equal to the
number of Shares so repurchased, except that no more than three million
(3,000,000) additional Shares shall be authorized for Options under this
proviso; and provided further that the total number of such available Shares
that may be used for Restricted Stock Awards under the Plan shall be limited to
three hundred thousand (300,000) plus the number of Shares reserved for
Restricted Stock use under the Prior Plans and transferred to this Plan pursuant
to Article 19. These Shares may be either authorized but unissued or reacquired
Shares.

         The following rules will apply for purposes of the determination of the
number of Shares available for grant under the Plan:

         (a) While an Award is outstanding, it shall be counted against the
             authorized pool of Shares, regardless of its vested status.

         (b) The grant of an Option or Restricted Stock shall reduce the
             Shares available for grant under the Plan by the number of
             Shares subject to such Award.


                                       5

<PAGE>   6

         (c) The grant of a Tandem SAR shall not reduce the number of
             Shares available for grant by the number of Shares subject to
             the related Option (i.e., there is no double counting of
             Options and their related Tandem SARs).

         (d) The grant of a Freestanding SAR shall reduce the number of
             Shares available for grant by the number of Freestanding SARs
             granted.

         (e) The Committee shall reduce the appropriate number of Shares
             from the authorized pool where a Performance Award is payable
             in Shares.

                                       6
<PAGE>   7


         (f) The Shares subject to outstanding Awards under Prior Plans
             which are transferred to this Plan in accordance with Article
             19 shall not reduce the number of Shares available for grant
             hereunder. The number of Shares reserved for use under the
             Prior Plans, upon transfer to this Plan in accordance with
             Article 19, shall be in addition to the total amount of Shares
             available for grant under this Plan as set forth in the first
             sentence of this Section 4.1.

         4.2 LAPSED AWARDS. If any Award granted under this Plan is cancelled,
forfeited, terminates, expires, or lapses for any reason (with the exception of
the termination of a Tandem SAR upon exercise of the related Option or the
termination of a related Option upon exercise of the corresponding Tandem SAR),
any Shares subject to such Award again shall be available for the grant of an
Award under the Plan. However, in the event that prior to the Award's
cancellation, forfeiture, termination, expiration, or lapse, the holder of the
Award at any time received one or more "benefits of ownership" pursuant to such
Award (as defined by the Securities and Exchange Commission, pursuant to any
rule or interpretation promulgated under Section 16 or any successor rule of the
Exchange Act), the Shares subject to such Award shall not be made available for
regrant under the Plan to Insiders, but shall be available for regrants under
the Plan to Participants who are not Insiders.

         4.3 ADJUSTMENTS IN AUTHORIZED SHARES AND PRICES. In the event of any
merger, reorganization, consolidation, recapitalization, separation,
liquidation, stock dividend, split-up, spin-off, Share combination, or other
change in the corporate structure of the Company affecting the Shares, such
adjustment shall be made in the number and class of Shares which may be
delivered under the Plan, and in the number, class and/or price of Shares
subject to outstanding Awards granted under the Plan, as may be determined to be
appropriate and equitable by the Committee, in its sole discretion, to prevent
dilution or enlargement of rights; and provided that the number of Shares
subject to any Award shall always be a whole number.

ARTICLE 5.  ELIGIBILITY AND PARTICIPATION

         5.1 ELIGIBILITY. Persons eligible to participate in this Plan include
all Employees of the Company and its Subsidiaries, as determined by the
Committee, including Employees who are members of the Board, but excluding
Directors who are not Employees.

         5.2 ACTUAL PARTICIPATION. Subject to the provisions of the Plan, the
Committee may, from time to time, select from all eligible Employees, those to
whom Awards shall be granted and shall determine the nature and amount of each
Award.

ARTICLE 6.  STOCK OPTIONS

         6.1 GRANT OF OPTIONS. Subject to the terms and provisions of the Plan,
Options may be granted to Employees at any time and from time to time as shall
be determined by the Committee. The Committee shall have discretion in
determining the number of Shares subject to Options granted to each Participant.
The Committee may grant ISOs, NQSOs, or a combination thereof. The maximum
number of Options which are available under the Plan for award to any individual
Participant over the duration of the Plan shall not exceed twenty percent (20%)
of the amount of shares available under the Plan for issuance in the form of
Options, as may be adjusted pursuant to the Plan.

         6.2 AWARD AGREEMENT. Each Option grant shall be evidenced by an Award
Agreement that shall specify the Option Price, the duration of the Option, the
number of Shares to which the Option pertains, and such other provisions as the
Committee shall determine. The Option Agreement also shall specify whether the
Option is intended to be an ISO within the meaning of Section 422 of the Code,
or a NQSO whose grant is intended not to fall under Section 422 of the Code.

                                       7
<PAGE>   8

         6.3 OPTION PRICE. The Option Price for each grant of an Option shall be
determined by the Committee; provided that the Option Price shall not be less
than the Fair Market Value of a Share on the date the Option is granted, subject
to adjustment pursuant to Section 4.3 herein. Options may not be repriced
without shareholder approval.

         6.4 DURATION OF OPTIONS. Each Option shall expire at such time as the
Committee shall determine at the time of grant; provided, however, that no
Option shall be exercisable later than the tenth (10th) anniversary date of its
grant.

         6.5 EXERCISE OF OPTIONS. Options granted under the Plan shall be
exercisable at such times and be subject to such restrictions and conditions as
the Committee shall in each instance approve, which need not be the same for
each grant or for each Participant.

         6.6 PAYMENT. (a) Options shall be exercised by the delivery of a
written notice of exercise to the Company, setting forth the number of Shares
with respect to which the Option is to be exercised, accompanied by full payment
for the Shares.

         (b) The Option Price upon exercise of any Option shall be payable to
the Company in full either: (i) in cash or its equivalent, or (ii) by tendering
to the Company, or certifying ownership by the Participant to the satisfaction
of the Company of, previously acquired Shares having an aggregate Fair Market
Value at the time of exercise equal to the total Option Price (provided that the
Shares which are tendered or certified must have been held by the Participant
for at least six (6) months prior to their tender or certification), or (iii) by
a combination of (i) and (ii).

         (c) The Committee also may allow cashless exercise as permitted under
Federal Reserve Board's Regulation T, subject to applicable securities law
restrictions, or by any other means which the Committee determines to be
consistent with the Plan's purpose and applicable law.

         (d) As soon as practicable after receipt of a written notification of
exercise and full payment, the Company shall deliver to the Participant Share
certificates in an appropriate amount based upon the number of Shares purchased
under the Option(s).

         6.7 RESTRICTIONS ON SHARE TRANSFERABILITY. The Committee may impose
such restrictions on any Shares acquired pursuant to the exercise of an Option
under the Plan as it may deem advisable, including, without limitation,
restrictions under applicable Federal securities laws, under the requirements of
any stock exchange or market upon which such Shares are then listed and/or
traded, and under any blue sky or state securities laws applicable to such
Shares.

         6.8 NONTRANSFERABILITY OF OPTIONS. No Options granted under the Plan
may be sold, transferred, pledged, assigned, or otherwise alienated or
hypothecated, other than by will or by the laws of descent and distribution.
Further, all Options granted to a Participant under the Plan shall be
exercisable during his or her lifetime only by such Participant. Notwithstanding
the foregoing, at the discretion of the Committee, an Award Agreement may permit
the transferability of an Option by a Participant solely to members of the
Participant's immediate family or trusts or partnerships for the benefit of such
persons.

ARTICLE 7.  STOCK APPRECIATION RIGHTS


                                       8

<PAGE>   9

         7.1 GRANT OF SARs. Subject to the terms and conditions of the Plan, a
SAR may be granted to an Employee at any time and from time to time as shall be
determined by the Committee. The Committee may grant Freestanding SARs, Tandem
SARs, or any combination of these forms of SAR. The maximum number of SARs which
are available under the Plan for award to any individual Participant over the
duration of the Plan shall not exceed ten percent (10%) of the amount of shares
available under the Plan for issuance in the form of SARs, as may be adjusted
pursuant to the Plan.

         The Committee shall have complete discretion in determining the number
of SARs granted to each Participant (subject to Article 4 herein) and,
consistent with the provisions of the Plan, in determining the terms and
conditions pertaining to such SARs. However, the grant price of a Freestanding
SAR shall be at least equal to the Fair Market Value of a Share on the date of
grant of the SAR. The grant price of Tandem SARs shall equal the Option Price of
the related Option. In no event shall any SAR granted hereunder become
exercisable within the first six (6) months of its grant. SARs may not be
repriced without shareholder approval.

         7.2 EXERCISE OF TANDEM SARs. Tandem SARs may be exercised for all or
part of the Shares subject to the related Option upon the surrender of the right
to exercise the equivalent portion of the related Option. A Tandem SAR may be
exercised only with respect to the Shares for which its related Option is then
exercisable.

         Notwithstanding any other provision of this Plan to the contrary, with
respect to a Tandem SAR granted in connection with an ISO: (i) the Tandem SAR
will expire no later than the expiration of the underlying ISO; (ii) the value
of the payout with respect to the Tandem SAR may be for no more than one hundred
percent (100%) of the difference between the Option Price of the underlying ISO
and the Fair Market Value of the Shares subject to the underlying ISO at the
time the Tandem SAR is exercised; and (iii) the Tandem SAR may be exercised only
when the Fair Market Value of the Shares subject to the ISO exceeds the Option
Price of the ISO.

         7.3 EXERCISE OF FREESTANDING SARs. Freestanding SARs may be exercised
upon whatever terms and conditions the Committee, at its sole discretion,
imposes upon them.

         7.4 SAR AGREEMENT. Each SAR grant shall be evidenced by an Award
Agreement that shall specify the grant price, the term of the SAR, and such
other provisions as the Committee shall determine.

         7.5 TERM OF SARs. The term of a SAR granted under the Plan shall be
determined by the Committee, at its sole discretion; provided, however, that
such term shall not exceed ten (10) years.

         7.6 PAYMENT OF SAR AMOUNT. Upon exercise of a SAR, a Participant shall
be entitled to receive payment from the Company in an amount determined by
multiplying:

         (a) The excess of the Fair Market  Value of a Share on the date of
             exercise  over the grant price of the SAR; by

         (b) The number of Shares with respect to which the SAR is exercised.

         At the discretion of the Committee, the payment upon SAR exercise may
be in cash, in Shares of equivalent value, or in some combination thereof.

         7.7 RULE 16B-3 REQUIREMENTS. Notwithstanding any other provision of the
Plan, the Committee may impose such conditions on exercise of a SAR (including,
without limitation, the right of the Committee to limit the time of exercise to
specified periods) as may be required to satisfy the requirements of any rule or
interpretation promulgated under Section 16 (or any successor rule) of the
Exchange Act.

                                       9
<PAGE>   10

         7.8 NONTRANSFERABILITY OF SARs. No SAR granted under the Plan may be
sold, transferred, pledged, assigned, or otherwise alienated or hypothecated,
other than by will or by the laws of descent and distribution. Further, all SARs
granted to a Participant under the Plan shall be exercisable during his or her
lifetime only by such Participant. Notwithstanding the foregoing, at the
discretion of the Committee, an Award Agreement may permit the transferability
of a SAR by a Participant solely to members of the Participant's immediate
family or trusts for the benefit of such persons.

ARTICLE 8.  RESTRICTED STOCK

         8.1 GRANT OF RESTRICTED STOCK. Subject to the terms and provisions of
the Plan, the Committee, at any time and from time to time, may grant Shares of
Restricted Stock to eligible Employees in such amounts as the Committee shall
determine.

         8.2 RESTRICTED STOCK AGREEMENT. Each Restricted Stock grant shall be
evidenced by a Restricted Stock Agreement that shall specify the Period of
Restriction, or Periods, the number of Restricted Stock Shares granted, and such
other provisions as the Committee shall determine.

         8.3 TRANSFERABILITY. Except as provided in this Article 8, the Shares
of Restricted Stock granted herein may not be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated until the end of the applicable
Period of Restriction established by the Committee and specified in the
Restricted Stock Agreement, or upon earlier satisfaction of any other
conditions, as specified by the Committee in its sole discretion and set forth
in the Restricted Stock Agreement. However, in no event may any Restricted Stock
granted under the Plan become vested in a Participant prior to six (6) months
following the date of its grant. All rights with respect to the Restricted Stock
granted to a Participant under the Plan shall be available during his or her
lifetime only to such Participant. Notwithstanding the foregoing, at the
discretion of the Committee, an Award Agreement may permit the transferability
of a Restricted Stock Award by a Participant solely to members of the
Participant's immediate family or trusts or partnerships for the benefit of such
persons, subject to any Period of Restriction.

         8.4 CERTIFICATE  LEGEND.  Each certificate  representing  Shares
of Restricted Stock granted pursuant to the Plan may bear the following legend:

             "The sale or other transfer of the Shares of stock represented
             by this certificate, whether voluntary, involuntary, or by
             operation of law, is subject to certain restrictions on
             transfer as set forth in the Premark International, Inc. 1994
             Incentive Plan, and in a Restricted Stock Agreement. A copy of
             the Plan and such Restricted Stock Agreement may be obtained
             from Premark International, Inc."

         The Company shall have the right to retain the certificates
representing Shares of Restricted Stock in the Company's possession until such
time as all conditions and/or restrictions applicable to such Shares have been
satisfied.

         8.5 REMOVAL OF RESTRICTIONS. Except as otherwise provided in this
Article 8, Shares of Restricted Stock covered by each Restricted Stock grant
made under the Plan shall become freely transferable by the Participant after
the last day of the Period of Restriction. Once the Shares are released from the
restrictions, the Participant shall be entitled to have the legend required by
Section 8.4 removed from his or her Share certificate.

         8.6 VOTING RIGHTS. During the Period of Restriction, Participants
holding Shares of Restricted Stock granted hereunder may exercise full voting
rights with respect to those Shares.

                                       10
<PAGE>   11

         8.7 DIVIDENDS AND OTHER DISTRIBUTIONS. The Committee shall have the
discretion to determine whether Participants who have been granted Restricted
Stock will be entitled to dividends and other distributions paid on Shares
during the Period of Restriction, and if so, the date of receipt. If any such
dividends or distributions are paid in Shares, the Shares shall be subject to
the same restrictions on transferability and forfeitability as the Shares of
Restricted Stock with respect to which they were paid. In the event that any
dividend constitutes a "derivative security" or an "equity security" pursuant to
Rule 16(a) under the Exchange Act, such dividend shall be subject to a vesting
period equal to the longer of: (i) the remaining vesting period of the Shares of
Restricted Stock with respect to which the dividend is paid; or (ii) six months.
The Committee shall establish procedures for the application of this provision.

         8.8 PERIOD OF RESTRICTION. Any Restricted Stock Award granted hereunder
shall have a Period of Restriction of not less than three years, except in the
following circumstances:

         (a) Any Restricted Stock Award which includes a performance-based
             condition may have a Period of Restriction as short as one
             year; and

         (b) An aggregate amount of Restricted Stock Awards not exceeding
             three percent (3%) of the Shares available pursuant to Section
             4.1 of the Plan, excluding Shares transferred to this Plan

             from Prior Plans pursuant to Article 19, may be issued without
             a minimum Period of Restriction.

ARTICLE 9.  PERFORMANCE AWARDS

         9.1 GRANT OF PERFORMANCE AWARDS. Subject to the terms of the Plan,
Performance Awards may be granted to eligible Employees at any time and from
time to time, as shall be determined by the Committee. The Committee shall have
complete discretion in determining the number, amount and timing of Awards
granted to each Participant. Such Performance Awards may take the form
determined by the Committee, including without limitation, cash, Shares,
Performance Units and Performance Shares, or any combination thereof.
Performance Awards may be awarded as short-term or long-term incentives.

         9.2 PERFORMANCE GOALS. (a) The Committee shall set performance goals at
its discretion which, depending on the extent to which they are met, will
determine the number and/or value of Performance Awards that will be paid out to
the Participants, and may attach to such Performance Awards one or more
restrictions, including, without limitation, a requirement that Participants pay
a stipulated purchase price for each Performance Share, or restrictions which
are necessary or desirable as a result of applicable laws or regulations.
Performance goals may be based upon, without limitation, Company-wide,
divisional, project team, and/or individual performance.

         (b) The Committee shall have the authority at any time to make
adjustments to performance goals for any outstanding Performance Awards which
the Committee deems necessary or desirable unless at the time of establishment
of goals the Committee shall have precluded its authority to make such
adjustments.

         (c) Performance Periods shall, in all cases, exceed six (6) months in
length.
                                       11
<PAGE>   12

         9.3 VALUE OF PERFORMANCE UNITS/SHARES. (a) Each Performance Unit shall
have an initial value that is established by the Committee at the time of grant.

         (b) Each Performance Share shall have an initial value equal to the
Fair Market Value of a Share on the date of grant.

         9.4 EARNING OF PERFORMANCE AWARDS. After the applicable Performance
Period has ended, the holder of Performance Awards shall be entitled to receive
the payout earned by the Participant over the Performance Period, to be
determined as a function of the extent to which the corresponding performance
goals have been achieved, except as adjusted pursuant to Section 9.2(b) or as
deferred pursuant to Article 11.

         9.5 TIMING OF PAYMENT OF PERFORMANCE AWARDS. Payment of earned
Performance Awards shall be made in accordance with terms and conditions
prescribed or authorized by the Committee. Participants may elect to defer, or
the Committee may require the deferral of, the receipt of Performance Awards
upon such terms as the Committee deems appropriate.

         9.6 NONTRANSFERABILITY. Performance Awards may not be sold,
transferred, pledged, assigned, or otherwise alienated or hypothecated, other
than by will or by the laws of descent and distribution. Further, a
Participant's rights under the Plan shall be exercisable during the
Participant's lifetime only by the Participant or the Participant's Beneficiary.
Notwithstanding the foregoing, at the discretion of the Committee, an Award
Agreement may permit the transferability of a Performance Award by a Participant
solely to members of the Participant's immediate family or trusts or
partnerships for the benefit of such persons.

ARTICLE 10.  BENEFICIARY

         10.1 DESIGNATION. Each Participant under the Plan may, from time to
time, name any Beneficiary or Beneficiaries (who may be named contingently or
successively). Each such designation shall revoke all prior designations by the
same Participant, shall be in a form prescribed by the Company, and shall be
effective only when filed by the Participant in writing with the Company during
the Participant's lifetime. Any such designation shall control over any
inconsistent testamentary or intervivos transfer by a Participant, and any
benefit of a Participant under the Plan shall pass automatically to a
Participant's Beneficiary pursuant to a proper designation pursuant to this
Section 10.1 without administration under any statute or rule of law governing
the transfer of property by will, trust, gift or intestacy.

         10.2 ABSENCE OF DESIGNATION. In the absence of any such designation
contemplated by Section 10.1, benefits remaining unpaid at the Participant's
death shall be paid pursuant to the Participant's will or pursuant to the laws
of descent and distribution.

ARTICLE 11.  DEFERRALS

         The Committee may permit a Participant to elect, or the Committee may
require at its sole discretion subject to the proviso set forth below, any one
or more of the following: (i) the deferral of the Participant's receipt of cash,
(ii) a delay in the exercise of an Option or SAR, (iii) a delay in the lapse or
waiver of restrictions with respect to Restricted Stock, or (iv) a delay of the
satisfaction of any requirements or goals with respect to Performance Awards;
provided, however, the Committee's authority to take such actions hereunder
shall exist only to the extent necessary to reduce or eliminate a limitation on
the deductibility of compensation paid to the Participant pursuant to (and so
long as such action in and of itself does not constitute the exercise of
impermissible discretion under) Section 162(m) of the Code, or any successor
provision thereunder. If any such deferral is required or permitted, the
Committee shall establish rules and procedures for such deferrals, including
provisions relating to periods of deferral, the terms of payment following the
expiration of the deferral periods, and the rate of earnings, if any, to be
credited to any amounts

                                       12
<PAGE>   13

deferred thereunder.

ARTICLE 12.  RIGHTS OF EMPLOYEES

         12.1 EMPLOYMENT. Nothing in the Plan shall interfere with or limit in
any way the right of the Company to terminate any Participant's employment at
any time, nor confer upon any Participant any right to continue in the employ of
the Company. For purposes of the Plan, transfer of employment of a Participant
between the Company and any one of its Subsidiaries (or between Subsidiaries)
shall not be deemed a termination of employment.

         12.2 PARTICIPATION. No Employee shall have the right to be selected to
receive an Award under this Plan, or, having been so selected, to be selected to
receive a future Award.

ARTICLE 13.  CHANGE IN CONTROL

         13.1 ACCELERATION OF VESTING. Notwithstanding any other provision of
the Plan to the contrary, in the event of a Change in Control, any Awards
outstanding and not then exercisable and vested as of the date such Change in
Control is determined to have occurred, shall become fully exercisable and
vested to the full extent of the original grant. Upon termination of employment
occurring as a consequence of a Change in Control, as determined by the
Committee, an Option shall remain exercisable for seven months following such
termination or until the expiration of the stated term of such Option, whichever
period is shorter.

         13.2 SURRENDER IN LIEU OF ACCELERATION. During the 60-day period from
and after a Change in Control (the "Exercise Period"), a Participant who holds
an Option shall have the right, in lieu of the payment of the exercise price for
the Shares being purchased under the Option and by giving notice to the Company,
to elect (within the Exercise Period) to surrender all or part of an Option to
the Company and to receive cash, within 30 days of such notice, in an amount
equal to the amount by which the Change in Control Price per Share on the date
of such election shall exceed the exercise price per Share under the Option (the
"Spread") multiplied by the number of Shares granted under the Option as to
which the right granted under this Section shall have been exercised.
Notwithstanding the foregoing, if any right granted pursuant to this Section
13.2 would make a Change in Control transaction ineligible for pooling of
interests accounting under the provisions of the Accounting Principles Board's
Opinion No. 16 that but for this Section 13.2 would otherwise be eligible for
such accounting treatment, the Committee shall have the ability to substitute
the cash payable pursuant to this Section 13.2 with shares of common stock
having a Fair Market Value equal to the cash that would otherwise be payable
hereunder and which will not render the Change in Control transaction ineligible
for pooling of interests accounting.

ARTICLE 14.  DEATH AND TERMINATION

         The Committee shall have the authority to establish provisions from
time to time governing the exercisability, vesting, forfeiture, payout or amount
of Awards in respect of a Participant's death or disability, or termination of
employment, whether as a consequence of retirement, resignation, involuntary
termination or otherwise.

ARTICLE 15.  AMENDMENT, MODIFICATION, AND TERMINATION

         15.1 AMENDMENT, MODIFICATION, AND TERMINATION. At any time and from
time to time, the Board may terminate, amend, or modify the Plan. However,
without the approval of the stockholders of the Company (as may be required by
the Code, by the short-swing profit rules of Section 16 of the Exchange Act, by
any national securities exchange or system on which the Shares are then listed
or reported, or by a regulatory body having jurisdiction with respect hereto),
no such amendment or modification may:


                                       13
<PAGE>   14

         (a) Increase the total number of Shares which may be issued under
             this Plan, except as provided in Article 4 hereof; or

         (b) Modify the eligibility requirements; or

         (c) Materially increase the benefits accruing under the Plan.

         15.2 AWARDS PREVIOUSLY GRANTED. No termination, amendment, or
modification of the Plan shall adversely affect in any material way any Award
previously granted under the Plan, without the written consent of the
Participant holding such Award. The Committee shall have the right to replace
any previously-granted Award under the Plan with an Award equal to the value of
the replaced Award at the time of replacement, without obtaining the consent of
the Participant holding such Award.

ARTICLE 16. WITHHOLDING

         16.1 TAX WITHHOLDING. The Company shall have the power and the right to
deduct or withhold, or require a Participant to remit to the Company, an amount
sufficient to satisfy Federal, state, and local

taxes (including the Participant's FICA obligation) required by law to be
withheld with respect to any taxable event arising under or as a result of this
Plan.

         16.2 SHARE WITHHOLDING. With respect to withholding required and/or
permitted upon the exercise of Options or SARs, upon the lapse of restrictions
on Restricted Stock, or upon any other taxable event hereunder, Participants may
elect, subject to the approval of the Committee, to satisfy the withholding
requirement, in whole or in part, by having the Company withhold Shares (or by
surrendering Shares previously owned which have been held for longer than six
months) having a Fair Market Value on the date the tax is to be determined equal
to the minimum statutory total tax which could be imposed on the transaction.
All elections shall be irrevocable, made in writing, signed by the Participant,
and elections by Insiders shall additionally comply with the requirements
established by the Committee.

ARTICLE I. ESTABLISHMENT AND CONSTRUCTION

1.1 ESTABLISHMENT AND AMENDMENT

Premark International, Inc. (the "Corporation") presently maintains an unfunded
deferred compensation plan, known as "The Premark International, Inc.
Supplemental Plan", which provides benefits to certain eligible employees of the
Corporation and its Affiliates. This plan was established effective as of
September 28, 1986, and was last amended and restated effective as of April 1,
1997. Said plan is hereby further amended and restated as set forth herein
effective as of January 1, 1999.

1.2 PURPOSE

The Corporation and its Affiliates sponsor several defined benefit plans and
defined contribution plans for the benefit of their U.S. employees and their
beneficiaries. These plans cover a variety of employee groups and are intended
to operate as "qualified plans" as that term is defined under the Code.

These qualified plans are subject to limitations under section 415 of the Code
that sometimes result in the diminution of allocations and benefits payable on
behalf of certain employees. This Plan is established to offset this diminution
for eligible employees. These benefits are intended to constitute an "unfunded
excess benefit plan" under Section 3(36) of ERISA.

These qualified plans also contain certain other restrictions, including
restrictions under Code sections 401 (a)(17), 401(k), and 402(g), that sometimes
result in a diminution of benefits available to certain highly compensated
employees. Also, these qualified plans exclude from the definition of
"compensation" amounts deferred by such employees to this Plan thereby resulting
in a diminution of benefits with respect to such deferrals. This Plan is
established to offset these diminutions, in part and to the extent provided
herein, for eligible employees. These benefits are intended as constituting an
unfunded deferred compensation plan for a select group of highly compensated
employees, as described in Sections 201(2), 301(a)(3), and 401 (a)(1) of ERISA.

           Plan, over (B) the amount allocated for the calendar year, to
           the Participant's Defined Contribution Plan account balance,
           without regard to the rate of contribution elected by the
           Participant under the Defined Contribution Plan; and,

      (2)  provided that the Participant has made a timely submission to
           the Administrator of an election to make before-tax deferrals
           for the calendar year to this Plan and the Defined

           limitations described in Section 3.1(b) and based on
           Compensation as defined in this Plan, over (B) the amount
           allocated for the calendar year, to the Participant's Defined

      Contributions elected by the Participant under this Plan, without
      regard to the Maximum Rate, and the rate of contributions elected to be
      made to the Defined Contribution Plan by salary reduction, without
      regard to the Maximum Rate, as in effect on January 1 of each calendar

<PAGE>   13

      is first eligible to participate as described in Section 3.2(c)) for
      which such elections are effective.

(c)   ELECTION TO PARTICIPATE. To be effective for a calendar year, an
      election to participate must be communicated in writing to the
      Administrator(s) prior to January 1st of such year. Once an election is
      made, it shall continue in effect unless and until the Participant
      notifies the Administrator(s) in writing of his intention to change or
      cancel his election, which cancellation or change shall not be
      effective for purposes of this Plan until the first day of the calendar
      year following the year in which the Administrator(s) receives such
      notification.

      (1)  For a person first becoming an eligible Participant under this
           Article 3.2(c), such election to participate must be
           communicated in writing to the Administrator(s) no later than
           thirty (30) days after the date he is notified of his
           eligibility to make such deferrals, in which event-

           (A)  the election shall be effective for the first payroll
                period occurring after the Administrator(s) receives
                such written election, and

           (B)  deferrals pursuant to such election shall be
                determined with reference to contributions to the
                Defined Contribution Plan beginning with said payroll
                period.

      (2)  If an election to participate is not timely filed, the
           eligible Participant may elect to participate at the beginning
           of any subsequent calendar year by submitting an election to
           the Administrator(s) prior to the beginning of any subsequent
           calendar year.

(d)   CONTRIBUTION RATE CHANGES. An election to participate and the rate of
      Salary Reduction Contributions elected by the Participant to this Plan
      and the rate of contributions elected to be made to the Defined
      Contribution Plan by salary reduction, without regard to the Maximum
      Rate, will be irrevocable and shall continue for the balance of the
      calendar year at the rate in effect at the beginning of the calendar
      year (or such later date as of which an individual is first eligible to
      participate as described in Section 3.2(c)).

3.3   EARNINGS

The benefit amount for each Participant pursuant to Section 3.2 shall be
adjusted and credited to each Participant's account at the end of each business
day to reflect an assumed rate of earnings, as follows:

                                       10

<PAGE>   14

(a)   Interest shall accrue on each day within a calendar quarter at an
      annual rate equal to the prime rate published in the Wall Street
      Journal at the beginning (January 1, April 1, July 1, October 1) of
      each calendar quarter plus one percent (the "Quarterly Rate"). The
      amount of earnings credited to each Participant shall be calculated
      based on the balance in the Participant's account at the end of each
      day, times the Quarterly Rate divided by 365 (or 366 during a leap
      year).

(b)   (1) In the event of a distribution (whether in a lump sum or
          installments and whether or not deferred), earnings shall be
          credited to the Participant's account in the manner and amount
          specified in Section 3.3 (a) through the day prior to the day
          in which the distribution is made or installment payments begin.

      (2) In the event the Participant elects to receive the distribution in
          installments pursuant to Section 6.3(b), the benefit amount shall
          be further credited with a rate of earnings for each day of the
          installment payment period in the manner and amount specified
          in Section 3.3(a).

3.4   ESTABLISHMENT OF ACCOUNTS

An account shall be established on the Corporation's financial ledgers for
Participants entitled to a benefit under Section 3.2. The amounts credited to
the account shall be equal to the amounts of the Participant's benefit under
Section 3.2 and Section 3.3. Amounts shall be credited to the Participant's
account at the same time a similar amount is (or would have been) credited to
the Participant's Defined Contribution Plan account.

3.5   BENEFIT PAYMENT OR COMMENCEMENT

(a)   Subject to Article V, in the event the Participant is to receive a lump
      sum distribution under Section 6.3(a) or elects to receive an immediate
      lump sum distribution under Section 6.3(b), the Participant's account
      established under Section 3.4 shall be payable as soon as practicable
      following the Participant's termination of employment with the
      Corporation and Affiliates.

(b)   Subject to Article V, each Participant who satisfies the requirements
      of Section 6.3(b) may elect to defer the lump sum payment or
      commencement of installment payments. In such event, the payment or
      commencement of installments shall be made as soon as practicable
      following the first anniversary of termination of employment with the
      Corporation and Affiliates. The Participant shall be permitted to
      revoke such election or to change the election in a manner consistent
      with Section 6.3(b), provided that such a relocation or change shall
      not be effective unless the Participant's new written election has been
      on file with the Administrator(s)

                                       11
<PAGE>   15

      for at least twelve (12) months prior to the date of Participant's
      termination of employment with the Employer.

(c)   To the extent the payment or commencement of a benefit is deferred
      under this Section, the amount so deferred shall continue to accrue an
      assumed rate of earnings, as described in Section 3.3.

3.6   FORM OF DISTRIBUTION

The account established for a Participant under Section 3.4, in conjunction with
the account(s) established under Section 4.3 shall be payable in the same manner
described under Section 6.3; or if applicable, Section 5.4.

      Plan shall become a Participant under this Article on the first date
      upon which his Compensation and/or benefits under the applicable

      and

(b) the amount of benefit the Participant actually receives under the Defined
Benefit Plan.

For purposes of this Section, "actuarial equivalent" shall be determined on the

      Corporation and Affiliates. The Participant shall be permitted to
      revoke such election or to change the election in a manner consistent

      not be effective unless the Participant's new written election has been

      to the date of Participant's termination of employment with the
      Employer.

(c)   To the extent the payment or commencement of a benefit is deferred
      under this Section, the amount so deferred shall accrue an assumed rate
      of earnings in the manner and amount described in Article III
      commencing on the date as of which payment would have commenced.

covered by the Corporation's change of control policy or an employment agreement
with the Corporation and Affiliates which becomes effective upon a Change of

and Affiliates as a result of the Change of Control pursuant to an employment
agreement or the Corporation's change of control policy. The benefit amount
payable will equal the excess of (a) over (b) below:

(a)   the amount of benefit which the Participant would have received under
      this Plan and all of his Employer-sponsored qualified retirement plans
      had the Participant been fully vested in such plans at his termination
      of employment with the Corporation and its Affiliates; and

                                       15
<PAGE>   19


ARTICLE VI.  GENERAL PROVISIONS

6.1   FUNDING

All amounts paid under this Plan shall be paid in cash from the general assets
of the Employer. Such amounts shall be reflected on the accounting records of
the Corporation but shall not be construed to create or require the creation of
a trust, custodial account, or escrow account. No Participant shall have any
right, title, or interest whatever in or to any investment reserves, accounts or
funds that the Corporation and Affiliates may purchase, establish, or accumulate
to aid in providing benefits under this Plan. Nothing contained in this Plan,
and no action taken pursuant to its provisions, shall create a trust or
fiduciary relationship of any kind between the Corporation and Affiliates and an
employee or any other person. Neither a Participant nor beneficiary of a
Participant shall acquire any interest greater than that of an unsecured
creditor.

6.2   VESTING

Benefits under this Plan shall become nonforfeitable when and to the extent they
would have become nonforfeitable had they been attributable to the applicable
qualified plan, except as otherwise provided in Section 5.2. Notwithstanding the
preceding sentence, a Participant or his beneficiary shall have no right to
benefits under this Plan if the Administrator(s) determines that he engaged in a
willful, deliberate, or gross act of commission or omission which is
substantially injurious to the finances or reputation of the Employer.

6.3   FORM OF DISTRIBUTION

Subject to Article V,

(a)   if the total value of the account(s) established for a Participant
      under Section 3.4 and/or Section 4.3 is equal to or less than $100,000,
      the total Plan benefit shall be payable in a single-sum distribution on
      the date determined pursuant to Sections 3.5(a) and 4.4(a). No other
      form of distribution will be available to the Participant.

(b)   if the total value of the account(s) established for a Participant
      under Section 3.4 and/or Section 4.3 exceeds $100,000, the total Plan
      benefit shall be payable in a single sum distribution on the date
      determined pursuant to Sections 3.5 (a) and/or 4.4(a). However, each
      Participant may elect that payment be made in either a single sum
      distribution or equal annual installments over a period of ten (10)
      years beginning with the date determined pursuant to Sections 3.5(b)
      and/or 4.4(b) provided that such election shall not be effective
      unless-

      (1)   the Participant's termination is on account of his Retirement, and


                                       16
<PAGE>   20

      (2) the Participant's written election of such alternative
          distribution has been on file with the Administrator(s) for at
          least twelve (12) months prior to the date of Participant's
          termination of employment with the Employer.

6.4   DEATH BENEFITS

(a)   Each Participant shall have the right to designate a beneficiary to
      receive death benefits under this Plan upon the death of the
      Participant. In the absence of a valid beneficiary designation, the
      Participants spouse or, if the Participant is unmarried, the
      Participant`s Beneficiary under the Defined Contribution Plan shall be
      the beneficiary of the Participant's benefits under this Plan.

(b)   In the event of a Participant's death prior to the commencement of
      benefits, his beneficiary will receive such benefits in a single-sum
      distribution as soon as practicable after the Participant's death.
      Benefits attributable to Defined Benefit Plans shall be calculated and
      subject to the same actuarial factors and adjustments used in
      determining the death benefits under the applicable Defined Benefit
      Plan.

(c)   If the Participant dies after the commencement of benefits and before
      all benefits have been distributed, the beneficiary shall receive all
      unpaid benefit amounts, if any, in the same manner and form of
      distribution as the Participant.

6.5   ADMINISTRATION

This Plan shall be administered by the Administrator(s). The Administrator(s)
shall have, to the extent appropriate, the same powers, rights, duties, and
obligations with respect to this Plan as they do for the applicable qualified
plans; provided, however, that the Administrator(s) determination of the
questions of construction and interpretation shall be final, binding, and
conclusive upon all persons.

6.6   CLAIMS AND APPEALS

If any part of an application for benefits under the Plan is denied, the
following claim procedure applies:

(a)   The Administrator(s) shall act upon each application for benefits
      within ninety (90) days after receipt of the application. If special
      circumstances require an extension of time, such Administrator(s) shall
      notify the applicant of the delay and shall act within one hundred
      eighty (180) days after receipt of the application. The
      Administrator(s) shall also explain the reason for the delay and
      indicate the date on which a decision may be expected. If the



                                       17

<PAGE>   21

    Administrator(s) does not act on an application for benefits within
    ninety (90) days (or one hundred eighty (180) days, if applicable), the
    application will be deemed to have been denied.

(b) If a claim is denied in whole or in part, the applicant shall be
    notified in writing of the following information:

    (1) the specific reasons for such denial;

    (2) specific reference to pertinent Plan provisions on which the denial
        is based;

    (3) a description of any additional material or information
        necessary for the claimant to perfect the claim and an
        explanation of why such material or information is necessary;
        and

    (4) an explanation of the Plan's claim review procedure.

(c) The applicant may appeal by delivering a written notice to the
    Administrator(s) within sixty (60) days after receiving notice of
    denial from the Administrator(s) or, if no notice of denial was
    received, within one hundred fifty (150) days (or two hundred forty
    (240) days, if applicable) after the claim was filed. The applicant's
    notice of appeal should:

    (1) request a review of his application for benefits by the
        Administrator(s);

    (2) set forth all of the grounds upon which his request for review
        is based and any facts in
        support; and

    (3) set forth any issues or comments which the applicant deems
        pertinent to his application.

If he appeals, the applicant may review pertinent documents at any reasonable
time and place specified by the Administrator(s) and may submit any additional
written materials pertinent to the appeal not set forth in the notice of appeal.

(d)  Any appeal will be reviewed by the Administrator(s). The applicant, who
     may be represented by any person, will be entitled to appear before the
     Administrator(s) to present his claim. The Administrator(s) will decide
     the appeal not later than sixty (60) days after receiving the notice of
     appeal. If special circumstances require an extension of time, a
     decision will be made as soon as possible, but not later than one
     hundred twenty (120) days after receipt of the notice of appeal. The
     Administrator(s) shall also explain the reason for the delay and
     indicate the date on which a decision may be expected. The decision of
     the Administrator(s) will be in writing and will

                                       18
<PAGE>   22

     state clearly the reasons for the decision including specific reference
     to the provisions of the Plan supporting the decision. The decision of
     the Administrator(s) on any and all appeals shall be final and
     conclusive upon all applicants.

6.7  EXPENSES

The expenses of administering the Plan shall be borne by the Employer.

6.8  INDEMNIFICATION AND EXCULPATION

The Administrator(s), its agents, and officers, directors, and employees of the
Corporation and its Affiliates shall be indemnified and held harmless by the
Corporation against and from any and all loss, cost, liability, or expense that
may be imposed upon or reasonably incurred by them in connection with or
resulting from any claim, action, suit, or proceeding to which they may be a
party or in which they may be involved by reason of any action taken or failure
to act under this Plan and against and from any and all amounts paid by them in
settlement (with the Corporation's written approval) or paid by them in
satisfaction of a judgement in any such action, suit, or proceeding. The
foregoing provision shall not be applicable to any person if the loss, cost,
liability, or expense is due to such person's gross negligence or willful
misconduct.

6.9  INTERESTS NOT TRANSFERABLE

The interests of the Participants and their beneficiaries under the Plan are not
subject to the claims of their creditors and may not be voluntarily or
involuntarily transferred, assigned, alienated, or encumbered.

Any action required of or permitted by the Corporation or an Affiliate under
this Plan shall be by approval of the Administrator(s) or any person or persons
authorized by the Administrator(s).

Amounts credited or paid under this Plan shall not be considered to be
compensation for the purposes of a qualified pension plan maintained by the
Corporation and Affiliates. The treatment of such amounts under other employee
benefit plans shall be determined pursuant to the provisions of such plans.

6.12 TAX LIABILITY

The Employer may withhold from any payment of benefits hereunder any taxes
required to be withheld and such sum as the Employer may reasonably estimate to
be necessary to cover any taxes for which the Employer may be liable and which
may be assessed with regard, to such payment.
