Dear Unitog Stockholder:
 
     The Board of Directors of Unitog Company cordially invites you to attend a
special meeting of Unitog stockholders ("Special Meeting") to be held at 10:00
a.m. local time on March 24, 1999, at the Unitog corporate offices located at
1300 Washington Street, Kansas City, Missouri.
 
     At the Special Meeting, you will be asked to approve the Agreement and Plan
of Merger dated January 9, 1999 between Unitog and Cintas Corporation (the
"Merger Agreement"). The Merger Agreement provides for the acquisition of Unitog
by Cintas. If the Merger Agreement is approved by Unitog stockholders and
certain other conditions are met, Unitog will become a subsidiary of Cintas and
Unitog stockholders will become Cintas stockholders.
 
   
     If the Merger is completed, Unitog stockholders will receive, as
consideration for their shares of Unitog common stock, a certain number of
shares of Cintas common stock determined by a conversion number. The conversion
number is targeted at a $37.87 per share value for Unitog common stock but
varies depending upon the average of the daily high and low sales prices of
Cintas common stock on the Nasdaq National Market for a specified period prior
to the Special Meeting. THE METHOD OF CALCULATING THE CONVERSION NUMBER IS SET
FORTH ON PAGE 1 OF THIS DOCUMENT. If the average Cintas trading price during the
specified period is less than $52 per share (thereby resulting in a value of
less than $37.87 per share of Unitog common stock), Unitog may (but is not
obligated to) terminate the Merger Agreement.
    
 
   
     Your Board of Directors has received opinions, from Goldsmith, Agio, Helms
Securities, Inc. and George K. Baum & Company, its financial advisors, dated
January 9, 1999, to the effect that as of such date the merger consideration to
be received by Unitog's stockholders pursuant to the Merger Agreement is fair to
such stockholders from a financial point of view.
    
 
     Your Board of Directors unanimously approved the Merger Agreement and
believes that the Merger is in the best interest of Unitog stockholders. The
Board unanimously recommends and advises that you approve the Merger Agreement
at the Special Meeting so that the Merger may be completed.
 
     In the materials accompanying this letter you will find a Notice of Special
Meeting of Stockholders, a Proxy Statement/Prospectus and a proxy card. The
Proxy Statement/Prospectus more fully describes the proposed Merger and the
Merger Agreement. We encourage you to read these materials carefully.
 
     Whether or not you plan to attend the Special Meeting, please take the time
to vote by completing, signing and returning to us the enclosed proxy card. A
postage paid envelope is enclosed for your convenience. If you sign, date and
return your proxy card without indicating how you want to vote, your proxy will
be counted as a vote in favor of the Merger Agreement. Even if you plan to
attend the Special Meeting, please complete, sign and return your proxy card. By
following certain procedures, you can later revoke your proxy if you wish.
 
                                          Sincerely,
 
                                      /s/ Randolph K. Rolf

              WHAT UNITOG STOCKHOLDERS WILL RECEIVE IN THE MERGER
 
   
The amount of Cintas common stock into which one share of Unitog common stock
would be converted in the Merger is referred to in this Proxy
Statement/Prospectus as the "conversion number". The conversion number is
determined by dividing the "target" Unitog Share Price of $37.87 (which includes
a reduction of $0.13 for certain environmental liability estimates described
below) by the average of the high and low sales prices of Cintas common stock as
reported on the Nasdaq National Market and calculated on a daily basis for the
period of 20 trading days ending the third trading day prior to the date of the
Unitog special stockholders meeting ("Cintas share price"), subject to certain
adjustments based on the Cintas share price as follows:
    
 
   
- - If the Cintas share price is greater than $66.43, the Cintas share price used
  to determine the conversion number is equal to $66.43 plus one-half of the
  amount by which the Cintas share price is greater than $66.43 (and thereby
  results in a value of more than $37.87 per Unitog share based upon the Cintas
  share price).
    
 
   
- - If the Cintas share price is equal to or between $52 and $66.43, each Unitog
  share would be exchanged for Cintas common stock with a $37.87 value (based
  upon the Cintas share price).
    
 
   
- - If the Cintas share price is less than $52, the Cintas share price used to
  determine the conversion number is deemed to be $52 (and thereby results in a
  value of less than $37.87 per Unitog share based upon the Cintas share price),
  but in such event the Unitog Board of Directors has the right to terminate the
  Merger Agreement. The Unitog Board is not required to exercise this right and
  does not currently intend to resolicit stockholder approval should it decide
  not to exercise such right. THEREFORE, UNITOG STOCKHOLDERS COULD RECEIVE
  MERGER CONSIDERATION VALUING THEIR SHARES OF UNITOG COMMON STOCK AT LESS THAN
  $37.87 PER SHARE.

Unitog expects to announce the average trading Cintas share price, the
conversion number and the per share merger consideration value on March 20,
1999, assuming a Unitog special stockholders meeting date of March 24, 1999.
Such information will also be available by calling 1-800-721-5711 on or after
March 20, 1999 and until the closing of the Merger.
    
 
Because the period for calculating the average trading price of Cintas common
stock will end before the date of the Unitog special stockholders meeting and
the subsequent closing of the Merger, the actual market value of the Cintas
common stock you receive as merger consideration may differ from the calculated
value of the merger consideration shown above which is provided here for
illustrative purposes only.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
Q:  WHY IS UNITOG PROPOSING THE MERGER?
 
A:  During the second calendar quarter of 1998, Unitog's Board of Directors
    began considering various strategic alternatives for enhancing the value of
    Unitog common stock. Unitog's financial advisors solicited proposals for the
    acquisition of Unitog, and the proposal submitted by Cintas was deemed by
    the Board as the most attractive. The merger of Unitog and Cintas presents
    an opportunity for Unitog stockholders to realize a premium over historic
    market prices for their shares through a tax-free re-organization.
 
Q:  WILL I OWE ANY FEDERAL INCOME TAX AS A RESULT OF THE MERGER?
 
A:  In general, you will not recognize any gain or loss for federal income tax
    purposes as a result of the Merger, except to the extent of any gain with
    respect to any cash payment you receive instead of any fractional share of
    Cintas common stock.
 
Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?
 
A:  The companies are working to complete the Merger as soon as possible. In
    addition to the approval of Unitog stockholders, certain other conditions
    must be met. The Merger is expected to be completed shortly after its
    approval by Unitog stockholders.
 
Q:  WHAT DO I NEED TO DO NOW?
 
A:  Just mail your completed, signed and dated proxy card in the enclosed return
    envelope as soon as possible so that your shares will be represented at the
    Unitog special meeting of stockholders, which will take place on March 24,
    1999.
 
Q:  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME?
 
A:  Your broker will vote your Unitog shares only if you provide instructions on
    how to vote. You should follow the directions provided by your broker
    regarding how to instruct your broker to vote your shares.
 
Q:  MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?
 
A:  Yes. You can change your vote at any time before your proxy is voted at the
    special meeting. You can do this in three ways. First, you can send Unitog a
    written statement that you would like to revoke your proxy. Second, you can
    send Unitog a new signed and later-dated proxy card. You should send any
    revocation or new proxy card to Unitog's Secretary at the address set forth
    at "Who Can Help Answer Questions?" on the following page. Third, you can
    attend the special meeting and vote in person. However, your attendance
    alone will not revoke your proxy.
 
Q:  SHOULD I SEND IN MY STOCK CERTIFICATE NOW?
 
A:  No. If the Merger is completed, Unitog stockholders will receive written
    instructions for exchanging their stock certificates.
 
Q:  WHAT HAPPENS TO MY DIVIDENDS?
 
A:  We expect no changes in Unitog's or Cintas' dividend policies before the
    Merger. In 1997, 1998 and 1999, Cintas declared $0.15, $0.18 and $0.22 per
    share in annual dividends, respectively. Payment of dividends by Cintas in
    the future will depend on business and financial conditions, earnings and
    other factors.

                                    SUMMARY
 
This summary highlights selected information from this Proxy
Statement/Prospectus and may not contain all of the information that is
important to you. To understand the Merger more fully and for a complete
description of the legal terms of the Merger, you should read carefully this
entire document and the documents we have referred to you. See "WHERE YOU CAN
FIND MORE INFORMATION."
 
Throughout this Proxy Statement/Prospectus, the term "Merger" refers to the
merger of a wholly-owned subsidiary of Cintas Corporation into Unitog Company,
with Unitog surviving the merger as a wholly-owned subsidiary of Cintas. The
term "Merger Agreement" refers to the Agreement and Plan of Merger dated January
9, 1999, a copy of which is included at the back of this Proxy
Statement/Prospectus as Appendix A.
 
                                 THE COMPANIES
 
UNITOG COMPANY
1300 Washington Street
Kansas City, Missouri 64105
(816) 474-7000
 
Unitog provides uniform rental services to a variety of industries and sells
custom-designed uniforms to national companies as well as smaller independent
businesses. Unitog provides rental services in 56 locations to over 60,000
customers in 34 states, and the province of Ontario, Canada. Unitog sells
garments directly to over 190,000 customers nationwide. Unitog operates seven
manufacturing facilities and four distribution centers.
 
CINTAS CORPORATION
6800 Cintas Blvd.
Cincinnati, Ohio 45262
(513) 459-1200
 
Cintas designs, manufactures, and implements corporate identity uniform programs
throughout the United States and Canada. Cintas provides uniform and other
ancillary products and services through a network of over 200 locations serving
over 300,000 customers in 39 states and two Canadian provinces. Cintas is also
engaged in the business of distributing and selling certain first aid and safety
products.
 
                             REASONS FOR THE MERGER
 
During the second calendar quarter of 1998, Unitog's Board of Directors began
considering various strategic alternatives for enhancing the value of Unitog
common stock. Unitog's financial advisors solicited proposals for the
acquisition of Unitog, and the proposal submitted by Cintas was deemed the most
attractive. The merger of Unitog and Cintas presents an opportunity for Unitog
stockholders to realize a premium over historic market prices for their shares
through a tax-free reorganization.
                         RECOMMENDATION TO STOCKHOLDERS
 
The Unitog Board of Directors unanimously recommends that Unitog stockholders
approve and adopt the Merger Agreement at the Unitog special stockholders
meeting so that the Merger may be completed.
 
                                   THE MERGER
 
   
In the Merger, a subsidiary of Cintas will merge with Unitog and Unitog, as the
survivor of the Merger, will become a subsidiary of Cintas. The stockholders of
Unitog will become stockholders of Cintas. For a description of what Unitog
stockholders will receive in the Merger, see "What Unitog Stockholders Will
Receive in the Merger" on page 2 of this Proxy Statement/Prospectus. Based on
the last reported sales price of Cintas common stock ($71 per share as of the
trading day immediately preceding the date of this Proxy Statement/Prospectus),
the aggregate dollar value of Cintas common stock to be issued in the Merger to
Unitog stockholders would be approximately $368 million. The actual value will
depend upon the average of the daily high and low sales prices of Cintas common
stock for the twenty trading days ending the third trading day prior to the
Unitog special stockholder meeting. We encourage you to read the Merger
Agreement because it is the legal document that governs the Merger.
    
 
                      CONDITIONS TO COMPLETING THE MERGER
 
Completion of the Merger depends upon satisfaction of a number of conditions,
including the following:
 
1. Unitog stockholders' approval and adoption of the Merger Agreement;
2. required regulatory approvals;
3. no governmental or legal actions prohibiting completion of the Merger;
 
                                       -5-
<PAGE>   13
 
4. receipt by both companies of letters from their independent public
   accountants to the effect that the Merger will qualify for "pooling of
   interests" accounting treatment;
5. Cintas' and Unitog's respective tax counsel's issuance of opinions regarding
   the federal income tax treatment of the Merger;
6. no breach of representations or warranties which would constitute a material
   adverse effect (as defined in the Merger Agreement) on Unitog or Cintas since
   January 9, 1999; and
7. neither Cintas nor Unitog terminates the Merger Agreement as set forth below.
 
To the extent permitted by law, certain of the closing conditions may be waived
by the party entitled to assert them. The Unitog Board does not currently intend
to resolicit stockholder approval for its waiver of any of the conditions
mentioned above.
 
                      TERMINATION OF THE MERGER AGREEMENT
 
The Merger Agreement may be terminated at any time by mutual agreement of Cintas
and Unitog.
 
Either Cintas or Unitog may terminate the Merger Agreement if:
 
1. legal or governmental authority prohibits the Merger on a final and
   non-appealable basis;
2. the Merger has not occurred by June 30, 1999; or
3. Unitog stockholders do not approve the Merger Agreement at the Unitog special
   stockholder's meeting.
 
Cintas may terminate the Merger Agreement if:
 
1. there has been a misrepresentation or breach of warranty or a failure to
   perform a covenant under the Merger Agreement on the part of Unitog which has
   a material adverse effect; or
2. the Unitog Board withdraws or materially modifies or changes its
   recommendation of the Merger Agreement in a manner adverse to Cintas.
 
Unitog may terminate the Merger Agreement if:
 
1. there has been a misrepresentation or breach of warranty or failure to
   perform a covenant under the Merger Agreement on the part of Cintas which has
   a material adverse effect;
2. the Board of Directors of Unitog, in the exercise of its fiduciary duty to
   Unitog stockholders, determines that a proposal superior to the Merger
   exists; or
3. the average trading Cintas share price is less than $52.00.
 
                                TERMINATION FEES
 
In the event of the termination of the Merger Agreement under certain
circumstances involving an acquisition proposal from a third party, Unitog will
be obligated to pay Cintas a termination fee of $10,960,867.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
Unitog and Cintas have structured the Merger to qualify as a tax-free
reorganization for federal income tax purposes. Assuming that the Merger
qualifies as a reorganization, neither Cintas, Unitog nor their stockholders
will recognize any gain or loss for federal income tax purposes in the Merger
except for any gain recognized with respect to cash payment received in lieu of
a fractional share of Cintas common stock. No ruling has been or will be sought
from the Internal Revenue Service as to the federal income tax consequences of
the Merger. TAX MATTERS ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE
MERGER TO YOU MAY DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT
YOUR OWN TAX ADVISOR TO UNDERSTAND FULLY THE TAX CONSEQUENCES OF THE MERGER TO
YOU.
 
                            COMPARATIVE STOCK PRICES
 
   
Cintas common stock is traded on the Nasdaq National Market under the symbol
"CTAS". Unitog common stock is traded on the Nasdaq National Market under the
symbol "UTOG". On January 8, 1999, the last trading day ending prior to the
public announcement of the proposed Merger, the last reported Nasdaq sales price
for Unitog common stock was $29.75 and for Cintas common stock was $72. On
February 18, 1999, the last reported sales price for Unitog common stock was
$37.875 and for Cintas common stock was $71.00.
    
 
Cintas will file an application to list on Nasdaq the shares of Cintas common
stock to be issued in the Merger.
 
                              ACCOUNTING TREATMENT
 
Unitog and Cintas expect the Merger to qualify as a "pooling of interests" under
applicable regulations, which means that Unitog and Cintas will be treated as if
they had always been combined for accounting and financial reporting purposes.

                         REQUIRED REGULATORY APPROVALS
 
The Hart-Scott-Rodino Act prohibits Cintas and Unitog from completing the Merger
until each has furnished certain information to the Antitrust Division of the
Department of Justice and the Federal Trade Commission and a required waiting
period has expired or been terminated. Cintas and Unitog each filed the required
notification and report forms with the Antitrust Division and FTC and, on
February 5, 1999, early termination of the waiting period was granted.
 
                             NO DISSENTERS' RIGHTS
 
Under applicable law, Unitog stockholders do not have appraisal rights in
connection with the Merger.
 
CERTAIN TRANSACTIONS/INTERESTS OF CERTAIN PERSONS
 
Some of the Unitog directors and officers have interests in the Merger that
differ, or are in addition to, the interests of Unitog stockholders. These
interests include:
 
- - certain Unitog directors and officers hold Unitog stock options that will vest
  upon completion of the Merger or would become vested and cashed out if their
  employment is terminated in certain circumstances within one year after the
  Merger;
- - certain Unitog officers are parties to severance and retention arrangements
  with Unitog which provide for certain benefits in the event of termination of
  employment under certain circumstances after the Merger; and
- - certain outside directors of Unitog will receive accelerated issuance of
  Unitog stock, in lieu of director fees, upon the completion of the Merger.
 
                                 VOTE REQUIRED
 
The affirmative vote of holders of at least a majority of the outstanding shares
of Unitog Common Stock is required to approve the Merger. Directors and
executive officers of Unitog are entitled to vote 1,296,739 shares or
approximately 13.8% of the outstanding shares of Unitog common stock.
 
                        COMPARISON OF STOCKHOLDER RIGHTS
 
The Delaware General Corporation Law and Unitog's Certificate of Incorporation
and Bylaws currently govern your rights as a stockholder of Unitog. Cintas is a
Washington corporation, and, if the Merger is completed, the Washington Business
Corporation Act and Cintas' Articles of Incorporation and Bylaws will govern
your stockholder rights. Washington law and Cintas' Articles of Incorporation
and Bylaws differ from Delaware law and Unitog's Certificate of Incorporation
and Bylaws in certain respects.
 
                         OPINIONS OF FINANCIAL ADVISORS
 
In deciding to approve the Merger, Unitog's Board of Directors considered the
opinions of its financial advisors, Goldsmith, Agio, Helms Securities, Inc. and
George K. Baum & Company, that the merger consideration (as expressed by the
conversion number) to be received by Unitog stockholders in the Merger was fair,
from a financial point of view. The written opinions of Goldsmith, Agio, Helms
Securities, Inc. and George K. Baum & Company are attached as Appendix B and
Appendix C, respectively, to this Proxy Statement/Prospectus. We encourage you
to read these opinions. In connection with delivering their opinions, Goldsmith,
Agio, Helms Securities, Inc. and George K. Baum & Company performed a variety of
financial analyses. These analyses included valuing discounted cash flows,
examining the historical trading prices of Unitog and Cintas common stock,
comparing Unitog to other publicly traded companies and reviewing and analyzing
prior similar transactions.

Note:
 
(A) During fiscal 1998, Cintas acquired Uniforms To You Companies (UTY) in a
    merger transaction accounted for as a pooling of interests. Prior to the
    merger, UTY had elected S Corporation status for income tax purposes. As a
    result of the merger, UTY terminated its S Corporation election. Cintas pro

    earnings per share reflects the pro forma tax expense of UTY as if UTY had
    been a C Corporation during the financial statement periods presented.

              SELECTED UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
   
The following selected unaudited pro forma combined financial data for the
combined company is based on adjustments to the historical consolidated
financial statements of Cintas and Unitog to give effect to the Merger using the
pooling of interests method of accounting for business combinations. You should
read the respective audited and unaudited consolidated financial statements and
related notes of Cintas and Unitog incorporated by reference into this Proxy
Statement/Prospectus. Additionally, you should read this information in
conjunction with the "UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS"
beginning on page 15. The pro forma information, while helpful in illustrating
the financial characteristics of the combined company under one set of
assumptions, does not attempt to predict or suggest future results. The pro
forma information also does not attempt to show how the combined company would
actually have performed had the companies been combined throughout these
periods. Only normal recurring adjustments necessary for a fair statement of
results of the unaudited historical interim periods have been included.

Notes:
    
 
   
(A) During fiscal 1998, Cintas acquired Uniforms To You Companies (UTY) in a
    merger transaction accounted for as a pooling of interests. Prior to the
    merger, UTY had elected S Corporation status for income tax purposes. As a
    result of the merger, UTY terminated its S Corporation election. Cintas pro
    forma net income, pro forma basic earnings per share and pro forma diluted
    earnings per share reflect the pro forma tax expense of UTY as if UTY had
    been a C Corporation during the financial statement periods presented.

                           COMPARATIVE PER SHARE DATA
 
Set forth below are net income, cash dividends and book value per common share
data separately for Cintas and Unitog on a historic basis, for Cintas on a
Cintas pro forma basis, for Cintas and Unitog on a pro forma combined basis and
on a pro forma combined basis per Unitog equivalent share. The relative exchange
ratios for the business combination are as follows:
 
   
- - .7283 Cintas share for one Unitog share -- assumes the average Cintas share
  price is $52.00
    
 
   
- - .6312 Cintas share for one Unitog share -- assumes the average Cintas share
  price is $60.00
    
 
   
- - .5701 Cintas share for one Unitog share -- assumes the average Cintas share
  price is $66.43
    
 
   
- - .5452 Cintas share for one Unitog share -- assumes the average Cintas share
  price is $72.50
    
 
   
- - .5172 Cintas share for one Unitog share -- assumes the average Cintas share
  price is $80.00
    
 
The Unitog equivalent share pro forma information shows the effect of the Merger
from the perspective of an owner of Unitog common stock. The information was
computed by multiplying the pro forma (using Cintas historical data) combined
information by the above respective exchange ratios.
 
   
You should read the respective audited and unaudited consolidated financial
statements and related notes of Cintas and Unitog incorporated by reference into
this Proxy Statement/Prospectus. Additionally, you should read this information
in conjunction with the "UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS"

Notes:
    
 
(A) The Cintas pro forma data is a result of Cintas acquiring Uniforms To You
    Companies (UTY) in a merger transaction accounted for as a pooling of
    interests in fiscal 1998. Prior to the merger, UTY had elected S Corporation
    status for income tax purposes. As a result of the merger, UTY terminated
    its S Corporation election. Cintas pro forma net income reflects the pro
    forma tax expense of UTY as if UTY had been a C Corporation during the
    financial statement periods presented.
 
(B) Unitog historical per share data is for the recasted six month periods ended
    October 25, 1998 and October 26, 1997, and for the recasted fiscal years
    ended April 26, 1998, April 27, 1997 and April 28, 1996.
 
(C) Pro forma earnings per Unitog equivalent common share is provided in
    accordance with additional disclosure requirements.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
The unaudited pro forma combined financial statements are based on the
historical consolidated financial statements of Cintas and Unitog and give
effect to the Merger as a pooling of interests. Such pro forma information
includes (1) the historical results of operations of Cintas for the six month
periods ended November 30, 1998 and November 30, 1997, the three fiscal years
ended May 31, 1998, and the historical balance sheet of Cintas as of November
30, 1998; and (2) the historical results of operations of Unitog for the
recasted six month periods ended October 25, 1998 and October 26, 1997, the
recasted three fiscal years ended April 26, 1998, April 27, 1997 and April 28,
1996 and the historical balance sheet of Unitog as of October 25, 1998. The
unaudited pro forma adjustments described in the accompanying notes are based
upon preliminary estimates and certain assumptions that the managements of
Cintas and Unitog believe are reasonable. Actual adjustments may differ from
those reflected in the unaudited pro forma combined financial statements. Cintas
and Unitog are still in the process of reviewing their respective accounting
policies relative to those utilized by the other entity. As a result of this
review, it may be necessary to restate certain amounts in Cintas' or Unitog's
financial statements to conform to those accounting policies that are most
appropriate. In management's opinion, any such restatements will not be
material.
 
Certain one-time expenses will be incurred as a result of combining Unitog and
Cintas. The unaudited pro forma earnings per share data do not reflect these
expenses. They do include merger-related costs associated with acquisitions
completed by both Cintas and Unitog since June 1995.
 
   
Environmental liability estimates for certain Unitog sites determined in
accordance with the Merger Agreement, together with new information concerning
another environmental matter which had been considered by Cintas, will result in
a charge of approximately $5 million to Unitog's pre-tax earnings during the
fourth quarter of Unitog's fiscal year ended January 31, 1999. The unaudited pro
forma combined financial statements do not reflect any adjustments for this
charge.
    
 
The Merger should provide the combined company with certain financial benefits
that include reduced operating expenses and enhanced revenue opportunities.
These anticipated cost savings and benefits are not reflected in the pro forma
information. The pro forma information, while helpful in illustrating the
financial characteristics of the combined company under one set of assumptions,
does not attempt to predict or suggest future results. The pro forma information
also does not attempt to show how the combined company would actually have
performed had the companies been combined throughout these periods. Only normal
recurring adjustments necessary for a fair statement of results of the unaudited
historical interim periods have been included.
 
For pro forma combined financial statement presentation, Cintas' three fiscal
years ended May 31, 1998 have been combined with Unitog's recasted fiscal years
ended April 26, 1998, April 27, 1997 and April 28, 1996. Cintas' six month
periods ended November 30, 1998 and November 30, 1997 have been combined with
Unitog's recasted six month periods ended October 25, 1998 and October 26, 1997.
 
   
The unaudited pro forma financial statements are not necessarily indicative of
the actual or future financial position or results of operations that would have
or will occur upon consummation of the Merger, and should be read in conjunction
with the audited and unaudited historical consolidated financial statements,
including the notes thereto, of Cintas and Unitog incorporated by reference and
the Selected Unaudited Pro Forma Combined Financial Data on page 10.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
(A) During 1998, Cintas acquired Uniforms To You Companies (UTY) in a merger
    transaction accounted for as a pooling of interests. Prior to the merger,
    UTY had elected S Corporation status for income tax purposes. As a result of
    the merger, UTY terminated its S Corporation election. Cintas pro forma
    presents net income and per share information for the pro forma tax expense
    of UTY as if UTY had been a C Corporation during the financial statement
    periods presented.
 
 (B) Represents the reclassification of certain selling and administrative
     expenses to conform the presentation of Unitog results to that of Cintas.
 
 (C) Represents the reclassification of depreciation and amortization expenses
     to conform the presentation of Unitog results to that of Cintas.
 
(D) Represents the change in an inventory obsolescence reserve as a result of
    (E).
 
 (E) Represents the change from the Unitog method of costing inventories on a
     last-in, first-out method to the Cintas method of costing inventories on a
     first-in, first-out method.
 
 (F) Represents the expensing of certain prepaid supplies to conform the
     presentation of Unitog results to that of Cintas.
 
(G) Represents the tax effect of the above Pro Forma Adjustments at the Cintas
    effective tax rate for all periods presented, respectively.
 
(H) Represents the reclassification of accrued compensation and related
    liabilities to conform the presentation of Unitog to that of Cintas.
 
 (I) Represents the reclassification of the current tax liability to conform the
     presentation of Unitog to that of Cintas.
 
 (J) Represents the conversion of Unitog common stock into Cintas common shares
     and reflects the impact of pro forma adjustments.
 
(K) Cintas and Unitog estimate that they will incur direct transaction costs of
    approximately $11.185 million associated with the Merger. These costs
    consist primarily of investment banking, legal, accounting, printing,
    regulatory filing fees, and retention bonuses to certain Unitog employees.
    The unaudited pro forma combined balance sheet reflects such expenses as if
    they had been paid as of November 30, 1998. Pro forma net income and
    earnings per share do not reflect these one-time transaction costs.
 
   
 (L) Per share information is based on an average Cintas per share price of
     $66.43 and a target Unitog Share Price of $37.87. Pro forma weighted
     average shares outstanding were computed using Unitog weighted average
     shares outstanding, for the respective period, multiplied by the conversion
     factor related to the average Cintas share price of $66.43 (.5701). This
     amount was added to Cintas weighted average shares outstanding for the
     respective period.

                           FORWARD LOOKING STATEMENTS
 
The Private Securities Litigation Reform Act of 1995 provides a safe harbor from
civil litigation for certain forward-looking statements. Forward-looking
statements include the information concerning future results of operations, cost
savings and synergies of Cintas and Unitog after the Merger set forth in
"QUESTIONS AND ANSWERS ABOUT THE MERGER," "SUMMARY," "THE MERGER," "THE
COMPANIES," "SELECTED UNAUDITED PRO FORMA COMBINED FINANCIAL DATA" and those
preceded by, followed by or that otherwise include the statements "should,"
"believe," "expect," "anticipate," "intend," "may," "will," "continue,"
"estimate" and other expressions that indicate future events and trends.
Although we believe that in making such statements our expectations are based on
reasonable assumptions, such statements may be influenced by risks and
uncertainties which could cause actual results and trends to be materially
different from historical results or those anticipated depending on a variety of
factors. These include, without limitation, performance of acquisitions,
economic and business changes, fluctuations in the cost of materials, labor
strikes and unemployment levels, unanticipated costs and expenses in integrating
Cintas' and Unitog's operations, demand and price for Cintas' and Unitog's
products and services, the reactions of competitors to the Merger in terms of
price and service, successfully addressing Year 2000 issues, and the outcome of
pending and future litigation and environmental matters. You should understand
that these factors, in addition to those discussed elsewhere in this document
and in documents which have been incorporated by reference, could affect the
future results of Cintas and Unitog, and could cause those results to be
materially different from those expressed in our forward-looking statements.
Cintas and Unitog do not undertake any obligation to update any forward looking
statements to reflect events or circumstances arising after the date of this
Proxy Statement/Prospectus.

<PAGE>   31
 
                                  RISK FACTORS
 
In considering whether to approve and adopt the Merger Agreement, the
stockholders of Unitog should consider, in addition to the other information
contained in this Proxy Statement/Prospectus, the following matters. Certain
capitalized terms used in this section are defined in other sections of this
Proxy Statement/Prospectus.
 
UNCERTAINTIES ASSOCIATED WITH THE INTEGRATION OF UNITOG AND ACHIEVEMENT OF COST
SAVINGS
 
The Merger will present challenges to Cintas involving the integration of the
operations, technologies and personnel of Cintas and Unitog, and possible
unanticipated liabilities, unanticipated costs and diversion of management
attention.
 
While Cintas believes that it will be able to successfully integrate and
profitably manage Unitog's business, there is no assurance that it can do so. In
addition, there can be no assurance that, following the Merger, Unitog's
businesses will achieve sales levels, profitability, cost savings or synergies
that justify the investment made or that the acquisition will be accretive to
Cintas' earnings in any future period.
 
POSSIBLE FLUCTUATION OF MERGER CONSIDERATION
 
   
The Merger Agreement provides for adjustments in the number of shares of Cintas
common stock to be issued to Unitog stockholders in exchange for their shares of
Unitog common stock. The amount of one share of Cintas common stock into which a
share of outstanding Unitog common stock would be converted in the Merger is
equal to the "Conversion Number." The Conversion Number is determined by
dividing the "target" Unitog share price of $37.87 (reduced from $38 for certain
environmental liability estimates) by an average trading price of Cintas common
stock referred to as the "Cintas share price." The consideration to be received
by a Unitog stockholder in exchange for one share of Unitog common stock is
referred to in this Proxy Statement/Prospectus as the "Merger Consideration."
The Cintas share price is equal to the average of the daily high and low sales
prices of Cintas common stock as reported on Nasdaq during the 20 trading day
period ending on the third trading day before the special stockholders meeting.
    
 
   
An adjustment applies if the Cintas share price is greater than $66.43 or less
than $52, as described below:
    
 
   
- - If the Cintas share price is greater than $66.43, the Cintas share price used
  to determine the Conversion Number is $66.43 plus one-half of the amount by
  which the Cintas share price exceeds $66.43. This will result in a value of
  more than $37.87 per share of Unitog common stock (based on the Cintas share
  price).
    
 
   
- - If the Cintas share price is less than $52, then the Cintas share price used
  to determine the Conversion Number is $52. This will result in a value of less
  than $37.87 (based on the Cintas share price). In such event, the Unitog Board
  may (but is not obligated to) terminate the Merger Agreement.
    
 
   
Unitog will announce the Cintas share price, the Conversion Number and the per
share Merger Consideration, on or about March 20, 1999. Such information will
also be available as a recorded message by calling 1-800-721-5711. We urge you
to obtain current market quotations for Cintas common stock. The market price of
Cintas common stock may change based upon changes in the business, operations or
prospects of Cintas, general market and economic conditions, regulatory
considerations and other factors.
    
 
   
Because the period for calculating the Cintas share price used to determine the
Conversion Number will end before the date of the Unitog special stockholders
meeting and the subsequent closing of the Merger, the actual market value of the
Cintas common stock you will receive as Merger Consideration may differ from the
value of the Merger Consideration calculated pursuant to the Merger Agreement.
    
 
ACQUISITIONS
 
From June 1, 1995 to the date of this Proxy Statement/Prospectus, Cintas has
issued approximately 10,500,000 shares of its common stock and paid
approximately $61 million in cash in 126 acquisitions. As part of its growth
strategy, Cintas intends to continue to actively pursue additional acquisition
opportunities. In order to achieve anticipated benefits from these acquisitions,
Cintas must successfully integrate any acquired business with its existing
operations, and while it believes it will be able to fully integrate these
businesses into Cintas, it can give
                                      -24-
<PAGE>   32
 
no assurance that it will be successful in this regard. Cintas can also give no
assurance that it will be able to complete future acquisitions or that all
future issuances of securities in connection with acquisitions will not dilute
the interests of its shareholders.
 
COMPETITION
 
Cintas' customers in the uniform rental and sales industry primarily choose
suppliers based upon quality of products, service and price. Leading uniform
competitors include UniFirst Corporation, ARAMARK Corporation and G&K Services,
Inc. In addition to Cintas' traditional uniform rental competitors, Cintas
anticipates that future competition may be with businesses that focus on selling
uniforms and other related items. If existing or future competitors seek to gain
or retain market share by reducing prices in reaction to the Unitog Merger or
otherwise, Cintas may be required to lower prices, which would hurt its
operating results. Cintas competitors also generally compete with Cintas for
acquisition candidates, which can increase the price for acquisitions and reduce
the number of available acquisition candidates.
 
ECONOMIC CONDITIONS
 
National or regional economic slowdowns or certain industry specific slowdowns
may hurt Cintas' business. Events or conditions in a particular area, such as
adverse weather and other factors, could also hurt operating results.
Furthermore, increases in interest rates may lead to a decline in economic
activity and adversely affect operating results. While Cintas does not believe
that its exposure is greater than that of its competitors, Cintas could be
adversely affected by increases in the prices of fabric, fuel, wages and other
components of product cost unless it could recover such increases through
increases in the prices for its services and products. Competitive and general
economic conditions might limit the ability of Cintas and its competitors to
increase prices to cover such increases.
 
ENVIRONMENTAL REGULATION
 
Various federal, state and local laws and regulations governing hazardous wastes
and other substances affect Cintas and its competitors in the uniform rental
industry. Specifically, industrial laundries use and must dispose of detergent
waste water and other residues. In the past, Cintas has settled, or contributed
to the settlement of, actions or claims brought against it which relate to the
disposal of hazardous materials. Cintas may have to pay material amounts to
compensate for the consequences of disposals in the future. Under environmental
laws, an owner or tenant of real estate may be required to pay the costs of
removing or remediating certain hazardous or toxic substances located on or in
or emanating from property whether or not the owner or tenant knew of or was
responsible for the presence of such hazardous or toxic substances. While Cintas
regularly engages in environmental due diligence in connection with
acquisitions, Cintas can give no assurance that locations that have been
acquired or leased or those being acquired in the Unitog Merger have been
operated in compliance with environmental laws and regulations during prior
periods or that future uses or conditions will not make Cintas liable under
these laws or expose Cintas to third-party actions including tort suits.
 
   
Cintas' environmental due diligence, which it conducted on certain Unitog
properties pursuant to Section 8.3 of the Merger Agreement, involved the
application of assessment techniques and tests beyond those normally followed.
This process resulted in an estimated additional environmental liability agreed
upon by the parties and led to an adjustment of the agreed upon price of $38 per
share for Unitog Common Stock to a price of $37.87, thereby lowering the amount
of consideration payable by Cintas in its acquisition of Unitog. While Cintas
believes that it has identified all material problems of this nature and that
the correction of these liabilities will not be material to its financial
condition or results of operations, there can be no assurances that the
remediation of these matters or the discovery of additional environmental
problems will not result in a material impact on Cintas' financial condition or
results of operations or expose it to third-party actions including tort suits
    
 
DEPENDENCE ON SENIOR MANAGEMENT; ABILITY TO ATTRACT AND RETAIN QUALITY PERSONNEL
 
Cintas' success depends in part on the skills, experience and efforts of senior
management and certain other key employees. If, for any reason, one or more
senior executives or key personnel were not to remain active with
 
                                      -25-
<PAGE>   33
 
Cintas, results of operations could be hurt. Future success also depends on
Cintas' ability to attract and retain qualified managers and technical and
marketing personnel, as well as sufficient numbers of hourly workers. Although
Cintas has an excellent track record of attracting and retaining quality people,
there is competition in the market for the services of such qualified personnel
and a tight market for hourly workers. The failure to attract and retain such
personnel or workers could hurt the results of operations.
 
INFORMATION SYSTEMS; YEAR 2000
 
Cintas has made a substantial investment in its information systems and intends
to spend significant amounts on information systems in the future. In
particular, Cintas has evaluated the programming code in its existing computer
and software systems as the Year 2000 approaches. The issue with respect to Year
2000 is whether systems will properly recognize date sensitive information when
the year changes to 2000. Systems that do not properly recognize such
information could generate erroneous data or cause complete system failures.
Cintas has completed an assessment of all of its software systems and has
determined what changes need to be made so that Cintas' computer systems will
function properly with respect to dates in the Year 2000 and thereafter. Cintas
does not expect that the total cost of those changes will be material, and will
expense the costs as incurred. Cintas expended most of its Year 2000 costs
during fiscal 1998, and expects to expense the remaining costs in fiscal 1999
when all changes are expected to be completed. Cintas is contacting key
suppliers to obtain certification of their systems Year 2000 compliance. After
Cintas identifies which vendors may fail to become Year 2000 compliant in a
timely fashion, Cintas will develop a strategy to minimize its risks which may
include contingency plans such as alternative suppliers or alternative
processes. Although Cintas believes that the likelihood of the Year 2000 having
a material effect on its operations, liquidity or financial position is remote,
there can be no such assurance that this will be the case.

                              THE SPECIAL MEETING
 
INTRODUCTION
 
This Proxy Statement/Prospectus is being furnished to the stockholders of Unitog
in connection with the solicitation of proxies by the Board of Directors of
Unitog Company ("Unitog") for use at the special meeting of Unitog stockholders
("Special Meeting") to be held on March 24, 1999 at 10:00 a.m., local time, at
Unitog's corporate offices located at 1300 Washington Street, Kansas City,
Missouri, and at any adjournments or postponements thereof. Each copy of this
Proxy Statement/Prospectus mailed to stockholders is accompanied by a proxy card
furnished in connection with the solicitation of proxies by the Unitog Board for
use at the Special Meeting.
 
MATTERS TO BE CONSIDERED; BOARD RECOMMENDATION
 
At the Special Meeting, stockholders will be asked to (i) approve the Merger
Agreement and the transactions contemplated thereby, and (ii) vote upon such
other business as may properly come before the Special Meeting or any
adjournments or postponements thereof (including, without limitation,
adjournment or postponement of the Special Meeting in order to allow for
additional solicitation of stockholder votes in order to obtain a quorum or in
order to obtain more votes in favor of the Merger Agreement). The Board of
Directors knows of no business that will be presented for consideration at the
Special Meeting other than the matters described in this Proxy
Statement/Prospectus.
 
The Unitog Board has determined that the Merger and the Merger Agreement are
advisable to and in the best interests of Unitog stockholders and has
unanimously approved the Merger and the Merger Agreement. ACCORDINGLY, THE BOARD
RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT. See "THE MERGER -- Background of the Merger" and " -- Reasons for the
Merger."
 
STOCKHOLDERS ARE REQUESTED PROMPTLY TO COMPLETE, DATE, SIGN AND RETURN THE
ACCOMPANYING PROXY CARD IN THE ENCLOSED POSTAGE-PAID ENVELOPE. FAILURE TO RETURN
A PROPERLY EXECUTED PROXY CARD OR TO VOTE AT THE SPECIAL MEETING WILL HAVE THE
SAME EFFECT AS A VOTE AGAINST THE MERGER AGREEMENT.
 
RECORD DATE AND VOTING
 
   
Only the holders of record of Unitog common stock ("Unitog Common Stock") as of
the close of business on February 18, 1999 (the "Record Date") are entitled to
notice of and to vote at the Special Meeting. At the close of business on the
Record Date, there were 9,406,623 shares of Unitog Common Stock outstanding and
entitled to vote, held by approximately 400 stockholders of record and
beneficially by approximately 1,500 stockholders. Directors and executive
officers of Unitog and its affiliates (as a group) were entitled to vote
1,296,739 shares of Unitog Common Stock, or approximately 13.8% of the
outstanding votes entitled to be cast at the Special Meeting. Holders of record
of Unitog Common Stock as of the close of business on the Record Date are
entitled to one vote per share on any matter voted on at the Special Meeting.
    
 
The presence, either in person or by proxy, of the holders of a majority of the
outstanding shares of Unitog Common Stock as of the Record Date is necessary to
constitute a quorum at the Special Meeting. Broker non-votes and abstentions
count for the purpose of determining a quorum at the Special Meeting. If a
quorum is not obtained, or if fewer shares are likely to be voted in favor of
approval and adoption of the Merger Agreement than the number required for
approval, it is expected that the Special Meeting will be adjourned for the
purpose of allowing additional time for soliciting and obtaining additional
proxies or votes or for any other purpose, including obtaining necessary
regulatory approvals. At any subsequent reconvening of the Special Meeting, all
proxies will be voted in the same manner as such proxies would have been voted
at the original convening of the meeting (except for any proxy which has been
effectively revoked or withdrawn).
 
STOCKHOLDERS SHOULD NOT FORWARD ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS.
IF THE MERGER IS CONSUMMATED, STOCK CERTIFICATES SHOULD BE DELIVERED IN
ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A LETTER OF TRANSMITTAL, WHICH WILL

BE SENT TO STOCKHOLDERS BY THE FIFTH THIRD BANK, CINCINNATI, OHIO IN ITS
CAPACITY AS THE EXCHANGE AGENT, PROMPTLY AFTER THE EFFECTIVE TIME.
 
VOTE REQUIRED
 
The affirmative vote of the holders of at least a majority of the outstanding
shares of Common Stock entitled to vote on the matters to be acted upon is
required to approve and adopt the Merger Agreement and the transactions
contemplated thereby. The failure to submit a proxy card (or vote in person at
the Special Meeting) or the abstention from voting by a stockholder (including
broker non-votes) shall have the same effect as a vote against the Merger
Agreement. Brokers who hold shares of Unitog Common Stock as nominees will not
have discretionary authority to vote shares with respect to the Merger Agreement
absent instructions from the beneficial owner thereof. The proxy holders named
in the enclosed proxy card will vote all shares of the Unitog Common Stock
represented by proxy cards that are properly signed and returned by stockholders
in accordance with the instructions contained therein. You may specify your
voting choices by marking the appropriate boxes on the proxy card. Shares as to
which an executed proxy card is returned but the stockholder has abstained from
voting on any matter are considered shares present at the Special Meeting for
purposes of determining a quorum and are included in determining whether the
proposals presented at the Special Meeting are approved (i.e., an abstention
would have the effect of a vote against the Merger Agreement and the
transactions contemplated thereby, and against such other business as may have
properly come before the Special Meeting, including adjournment or postponement
thereof). Shares held by a broker in street name and for which an executed proxy
card (without voting instructions) is returned to Unitog by such broker will be
considered present at the Special Meeting for purposes of determining a quorum
but will not be voted with respect to such matter (which has the effect of
voting against the proposal). IF YOU PROPERLY SIGN AND RETURN THE PROXY CARD
SENT TO YOU BY UNITOG, BUT DO NOT SPECIFY YOUR VOTING CHOICES, YOUR SHARES WILL
BE VOTED "FOR" ALL PROPOSALS AND TO APPROVE AND ADOPT THE MERGER AGREEMENT AS
RECOMMENDED BY THE BOARD OF DIRECTORS.
 
The Board is not aware of any matters other than that set forth in the Notice of
Special Meeting of Stockholders that may be brought before the Special Meeting.
If any other matters properly come before the Special Meeting, including a
motion to adjourn the Special Meeting for the purpose of soliciting additional
proxies, the persons named in the accompanying proxy will vote the shares
represented by all properly executed proxies on such matters in their
discretion, except that shares represented by proxies which have been voted
"against" the Merger Agreement will not be used to vote "for" adjournment of the
Special Meeting for the purpose of allowing additional time for soliciting
additional votes "for" the Merger Agreement.
 
REVOCABILITY OF PROXIES
 
A stockholder may revoke a proxy at any time prior to its exercise by (i)
delivering to Robert M. Barnes, Vice President- General Counsel and Secretary,
Unitog Company, 1300 Washington Street, Kansas City, Missouri 64105, a written
notice of revocation prior to the Special Meeting, (ii) delivering, prior to the
Special Meeting, a duly executed proxy bearing a later date, or (iii) attending
the Special Meeting and voting in person. The presence of a stockholder at the
Special Meeting will not in and of itself automatically revoke such
stockholder's proxy.
 
SOLICITATION OF PROXIES
 
Except for the costs of filing this Proxy Statement/Prospectus with the
Securities and Exchange Commission ("SEC"), printing and mailing this Proxy
Statement/Prospectus, and the filing fee paid for filings made under the
Hart-Scott- Rodino Act ("HSR Act"), which costs are shared equally by Cintas and
Unitog, Unitog will bear the costs of soliciting proxies from stockholders. In
addition to soliciting proxies by mail, directors, officers and employees of
Unitog, without receiving additional compensation therefor, may solicit proxies
by telephone, fax and telegram or in person. Arrangements also will be made with
brokerage firms and other custodians, nominees and fiduciaries to forward
solicitation materials to the beneficial owners of shares held of record by such
persons, and Unitog will reimburse such brokerage firms, custodians, nominees
and fiduciaries for reasonable out-of-pocket expenses incurred by them in
connection therewith. Unitog has retained Beacon Hill Partners, Inc., a
professional soliciting organization, to aid in the solicitation of proxies.
Beacon Hill Partners, Inc.'s fee for solicitation of the proxies is estimated to
be $5,000 plus reimbursement for out-of-pocket costs and expenses.

ADJOURNMENT OF THE SPECIAL MEETING
 
A vote (i) in person by a stockholder for adjournment of the Special Meeting, or
(ii) for the last proposal on the proxy card authorizing the named proxies to
vote the shares covered by such proxy in their discretion with respect to such
other business as may properly come before the Special Meeting, which would
allow such named proxies in their discretion to vote to adjourn the Special
Meeting, would allow for additional solicitation of stockholder votes in order
to obtain a quorum or in order to obtain more votes in favor of the Merger
Agreement. The Board of Directors recommends and advises that the stockholders
vote in person in favor of any adjournment of the Special Meeting so suggested
by such Board to allow time to solicit additional votes in order to obtain a
quorum or to obtain more votes in favor of the Merger Agreement, or in favor of
the last proposal on the proxy card. See "Vote Required" for the effect of
abstentions and broker non-votes with respect to a vote on a proposal to adjourn
the Special Meeting and on such other proposals.
 
NO DISSENTERS' RIGHTS
 
Pursuant to Delaware General Corporation Law sec.262(b)(1), holders of Unitog
Common Stock are not entitled to appraisal rights in connection with the Merger.
 
                                   THE MERGER
 
FORM OF THE MERGER
 
If the Merger is consummated, Unitog will be acquired by Cintas through the
merger of Cintas Image Acquisition Company, a Delaware corporation wholly-owned
by Cintas, with and into Unitog, with Unitog being the surviving corporation and
becoming a wholly-owned subsidiary of Cintas.
 
BACKGROUND OF THE MERGER
 
At a special directors meeting held on January 9, 1999, the Unitog Board
determined that the Merger was advisable to and in the best interests of the
stockholders of Unitog, approved the Merger Agreement and the transactions
contemplated thereby and recommended to the Unitog stockholders that they vote
for approval and adoption of the Merger Agreement. Immediately following this
meeting, Unitog, Cintas and its subsidiary entered into the Merger Agreement.
The following discussion sets forth certain information relating to the
background of the discussions and meetings leading up to the Merger.
 
For the last three fiscal years, Unitog has not fulfilled certain performance
objectives previously established by its Board of Directors. Earnings of Unitog
have not met expectations of many securities analysts and stockholders during
that same period. Unitog management believes the primary reasons for
disappointing earnings included the difficulty of integrating certain
acquisitions in the Michigan area and difficulties which resulted in reduced
revenues and extra costs in Unitog's direct sale business when converting to a
new order entry system.
 
   
During the second calendar quarter of 1998, the Unitog Board began discussing
strategic alternatives for enhancing the value of Unitog Common Stock. Among the
alternatives considered were (i) continuation of operations with a restructuring
of Unitog's business and (ii) a sale or other strategic transaction. In August
1998, the Unitog Board determined that one or more financial advisors should be
retained to assist the Board in its consideration of the foregoing alternatives.
    
 
As a result of these discussions and determinations, the Unitog Board
interviewed several investment banking firms and on September 18, 1998, engaged
Goldsmith, Agio, Helms and Company and George K. Baum & Company to evaluate a
sale, strategic transaction or change in business strategy. G. Kenneth Baum and
William D. Thomas are both directors of Unitog. Mr. Baum is an employee and Mr.
Thomas serves as Vice President of George K. Baum & Company. George K. Baum &
Company was one of the underwriters of Unitog's initial public offering in 1989
and has served as a financial adviser to Unitog in connection with several past
acquisitions and financings. See "THE MERGER -- Interests of Certain Persons in
the Merger -- Affiliation with Financial Advisor."
 
                                      -29-
<PAGE>   37
 
Following an analysis by the financial advisors, in early October 1998, the
Unitog Board authorized Goldsmith, Agio, Helms and Company and George K. Baum &
Company to solicit indications of interest for the acquisition of Unitog in
order to determine the potential for recognition of value through a sale. The
Unitog Board had determined that a sale transaction was a better alternative for
enhancing value of Unitog Common Stock than the other alternatives, in light of
the evaluation by the financial advisors.
 
After the Unitog Board's authorization to solicit such indications of interest,
on October 9, 1998, Goldsmith, Agio, Helms and Company contacted several
prospective purchasers to determine if these parties were interested in
evaluating the potential acquisition of a United States based company in the
commercial garment industry. Twelve of those parties were interested in
proceeding with an evaluation of the opportunity and each signed a
confidentiality agreement and received a confidential memorandum that described
Unitog. Seven of the twelve parties submitted preliminary indications of
interest based upon the review of the confidential memorandum.
 
Based upon these preliminary indications, six interested parties were invited to
meet with Unitog management and examine certain confidential information
assembled in a data room. The confidential information included tax and
financial records, operating data, information on environmental and legal
matters, business contracts, employee benefits and compensation data and other
business information. In addition, counsel for Unitog provided certain
interested parties with proposed drafts of definitive merger agreements.
 
On December 11, 1998, Cintas and other parties submitted definitive proposals
for the acquisition of Unitog. The definitive proposals included markups of
Unitog's proposed merger agreement showing each party's requested changes to
such agreement. Based upon an analysis of the definitive proposals received, on
December 16, 1998, the Unitog Board concluded that the offer by one party was
superior and negotiations of a definitive agreement with such party were
pursued. Cintas then submitted revised proposals or clarifications on December
18, 24 and 29, 1998. The Unitog Board rejected the December 29, 1998 Cintas
proposal and communicated its reasons for such rejection on December 31, 1998.
In correspondence dated January 4 and 5, 1999, Cintas presented revised
financial terms which appeared to make its proposal superior to the proposal
from the other party previously considered superior by the Unitog Board on
December 16, 1998.
 
From January 6 through January 8, 1999, representatives of Unitog, along with
its legal counsel and representatives of Goldsmith, Agio, Helms and Company, met
with representatives of Cintas and its legal counsel in Kansas City, Missouri,
to discuss Cintas' proposal and to negotiate the proposed agreement. By the
afternoon of January 7, 1999, most open issues were resolved. The Unitog Board
met and Goldsmith, Agio, Helms and Company and George K. Baum & Company made a
financial presentation and reviewed the sales process to date, and Unitog's
legal counsel reviewed the terms of the current draft of the Merger Agreement.
An in-depth discussion of the Merger Agreement then followed. By the morning of
January 8, 1999, the remaining open items were resolved, and the Cintas Board
met and approved the Merger Agreement. On Saturday, January 9, 1999, the Unitog
Board reconvened to consider the final Merger Agreement. At this meeting,
Goldsmith, Agio, Helms and Company (through its affiliate, Goldsmith, Agio,
Helms Securities, Inc.) and George K. Baum & Company delivered their oral
opinions, which were subsequently confirmed in writing and described below under
"THE MERGER -- Opinions of Financial Advisors", to the effect that as of January
9, 1999, the proposed merger consideration to be received by holders of Unitog
Common Stock is fair from a financial point of view to such holders. Unitog's
legal counsel then described those terms of the Merger Agreement that had been
modified since the prior meeting of the Unitog Board. Following the discussion,
at this special meeting the Unitog Board approved the Merger Agreement by
unanimous vote of those directors present. A statement of unanimous consent was
executed by the entire Unitog Board after January 9, 1999 in order to include
the approval of the Merger Agreement by two directors who were not able to
attend the January 9 meeting but who had been present or participated in
virtually all prior meetings of the Unitog Board regarding this matter and who
were apprised of the relevant discussions at the January 9 meeting. On January
9, 1999, the Merger Agreement was executed and delivered by Unitog and the
proposed Merger was publicly announced by Unitog and Cintas on Monday, January
11, 1999.
 
   
The Merger Agreement established a target price of $38 per Unitog share. This
price, divided by the applicable price for Cintas Common Stock, determines the
amount of Cintas Shares to be issued in exchange for Unitog shares. Section 8.3
of the Merger Agreement provided that the target $38 Unitog share price was
subject to reduction if certain environmental liability estimates regarding
Unitog exceeded a specified level. On February 17, 1999, after consultation with
their respective environmental consultants, Unitog and Cintas agreed
    
 
                                      -30-
<PAGE>   38
 
   
on the amount of the estimated environmental liability, thereby reducing the
Unitog share price from $38 to $37.87.
    
 
REASONS FOR THE MERGER
 
During the second calendar quarter of 1998, Unitog's Board of Directors began
considering various strategic alternatives for enhancing the value of Unitog
common stock. Unitog's financial advisors solicited proposals for the
acquisition of Unitog, and the proposal submitted by Cintas was deemed the most
attractive. The merger of Unitog and Cintas pursuant to the terms of the Merger
Agreement presents an opportunity for Unitog stockholders to realize a premium
over historic market prices for their shares through a tax-free reorganization.
 
OPINIONS OF FINANCIAL ADVISORS
 
Goldsmith, Agio, Helms Securities, Inc.
 
   
On January 9, 1999, Goldsmith, Agio, Helms and Company, through its affiliate,
Goldsmith, Agio, Helms Securities, Inc. ("GAHS"), delivered to the Unitog Board
GAHS' oral opinion, which was confirmed subsequently in writing, to the effect
that, as of such date, and subject to the assumptions, procedures and
limitations set forth therein, the proposed Merger Consideration to be received
by the holders of Unitog Common Stock pursuant to the Merger Agreement is fair
from a financial point of view to Unitog stockholders. The Merger Consideration
is subject to a possible environmental adjustment as outlined in Section 8.3 of
the Merger Agreement. Pursuant to Section 8.3 of the Merger Agreement, the
Unitog share price of $38 is subject to adjustment based on specified
environmental investigations. Pursuant to Section 10.1 of the Merger Agreement,
either party may terminate the Merger Agreement if the aggregate adjustment to
the Unitog share price pursuant to Section 8.3 is more than $2.00. Therefore,
the GAHS analysis addressed a Merger value for Unitog at $36.00 to $38.00.
    
 
A copy of GAHS' opinion dated January 9, 1999, which sets forth the assumptions
made, matters considered, and limits on the review taken, is attached as
Appendix B to this Proxy Statement/Prospectus and is incorporated herein by
reference. Unitog stockholders are urged to read the GAHS opinion in its
entirety. The description of the GAHS opinion set forth herein is qualified in
its entirety by reference to the full text of such opinion. The GAHS opinion is
rendered for the benefit and use of the Board of Directors of Unitog in
connection with the Board's consideration of the Merger and does not constitute
a recommendation to any holder of Unitog Common Stock as to how such stockholder
should vote with respect to the Merger.
 
In arriving at its opinion, GAHS undertook such reviews, analyses and inquiries
as it deemed necessary and appropriate under the circumstances. Among other
things, GAHS (i) reviewed the Merger Agreement; (ii) analyzed financial and
other information that is publicly available relating to Cintas; (iii) analyzed
financial and other information that is publicly available relating to Unitog;
(iv) analyzed certain financial and operating data of Unitog that has been made
available to GAHS by Unitog; (v) visited certain facilities of Unitog and
discussed with management of Unitog the financial condition, operating results,
business outlook and prospects of Unitog; (vi) analyzed the valuations of
publicly traded companies that GAHS deemed comparable to Unitog; (vii) performed
a discounted cash flow analysis of Unitog based on financial projections that
Unitog management provided to GAHS; and (viii) analyzed the financial terms of
certain transactions GAHS deemed similar to the Merger that have recently been
effected.
 
GAHS relied upon and assumed the accuracy, completeness, and fairness of the
financial statements and other information furnished by, or publicly available
relating to, Unitog or Cintas, or otherwise made available to GAHS, and did not
assume responsibility independently to verify such information. GAHS further
relied upon assurances by Unitog that the information provided to GAHS had a
reasonable basis, and with respect to projections and other business outlook
information, reflected the best available estimates, and that Unitog was not
aware of any information or fact that would make the information provided to
GAHS incomplete or misleading. In arriving at its opinion, GAHS did not perform
any appraisals or valuations of specific assets or liabilities of Unitog or
Cintas and expressed no opinion regarding the liquidation value of Unitog or
Cintas or any of their respective assets. The GAHS opinion is based upon the
information available to GAHS and the facts and
 
                                      -31-
<PAGE>   39
 
circumstances as they existed and are subject to evaluation on the date of the
opinion; events occurring after the date of the opinion could materially affect
the assumptions used in preparing the opinion.
 
GAHS assumed that the Merger will be accounted for as a pooling of interests in
accordance with generally accepted accounting principles ("GAAP") and that the
Merger qualifies for such accounting treatment under GAAP. GAHS also assumed
that the Merger will constitute a reorganization under Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code"). GAHS made no independent
investigation of any legal or accounting matter that may affect Unitog and
assumed the correctness of the legal and accounting advice provided to Unitog
and its Board of Directors.
 
The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The summary
of the GAHS analyses set forth below does not purport to be a complete
description of the presentation by GAHS to Unitog's Board of Directors. In
arriving at its opinion, GAHS did not attribute any particular weight to any
analysis or factor considered by it, but rather made qualitative judgments as to
the significance and relevance of each analysis and factor. Accordingly, GAHS
believes that its analyses and the summary set forth below must be considered as
a whole and that selecting portions of its analyses, or of the summary, without
considering all factors and analyses, could create an incomplete view of the
processes underlying the analyses set forth in the GAHS presentation to the
Unitog Board of Directors and its opinion.
 
The analyses performed by GAHS (and summarized below) are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less favorable than suggested by such analyses. Additionally, analyses
relating to the values of businesses do not purport to be appraisals or to
reflect the prices at which businesses actually may be acquired.
 
Discounted Cash Flow Analysis. GAHS analyzed the valuation of Unitog based on
the unlevered discounted cash flow of the projected five-year financial
performance estimates of Unitog prepared by Unitog management. Unitog's weighted
average cost of capital for purposes of this analysis was calculated to
approximate 10.6 percent. Terminal values were calculated by applying both an
earnings before interest, taxes, depreciation and amortization ("EBITDA")
multiple of 7.0x to the projected EBITDA of Unitog in fiscal year 2004 and by
applying a 5% perpetual growth rate to the projected free cash flow in fiscal
year 2004. Based on this analysis, Unitog's implied per share equity values
ranged from $26.07 to $27.23.
 
Analysis of Publicly Traded Comparable Companies. GAHS analyzed selected
historical and projected financial, operating, and stock market data of Unitog,
Cintas, and other publicly traded companies that GAHS deemed to be comparable to
Unitog and Cintas. The three companies deemed by GAHS to be reasonably
comparable to Unitog and Cintas in terms of products and services offered,
markets served and business prospects were 1) G&K Services, Inc., 2) UniFirst
Corporation, and 3) Angelica Corporation (the "Comparable Companies"). No
company utilized in the Comparable Company Analysis is identical to Unitog or
Cintas. Accordingly, an analysis of the results of the foregoing necessarily
involves complex considerations and judgments concerning the differences in
financial and operating characteristics of Unitog and Cintas and other factors
that could affect the public trading value of the comparable companies to which
they are being compared.
 
GAHS examined certain publicly available financial data of the Comparable
Companies including the ratio of firm value (equity value plus total debt less
cash and equivalents) to latest-12-month ("LTM") revenue; the ratio of firm
value to LTM EBITDA; the ratio of firm value to LTM earnings before interest and
taxes ("EBIT"); and the ratio of equity value to LTM and projected net income.
 
   
This analysis showed that the Comparable Companies had a multiple of firm value
to revenue ranging from 0.5x to 2.5x, with a mean of 1.4x and a median of 1.1x,
compared with 1.6x to 1.7x for Unitog based on a Merger value of $36.00 to
$38.00 (pursuant to the possible environmental adjustment outlined in Section
8.3 of the Merger Agreement); a multiple of firm value to EBITDA ranging from
5.9x to 11.8x, with a mean of 7.9x and a median of 5.9x, compared with 10.3x to
10.7x for Unitog based on a Merger value of $36.00 to $38.00; a multiple of firm
value to EBIT ranging from 8.8x to 17.5x, with a mean of 12.0x and a median of
9.7x, compared with 17.7x to 18.5x for Unitog based on a Merger value of $36.00
to $38.00; and a multiple of equity value to LTM net income ranging from 13.1x
to 32.2x with a mean of 22.0x and a median of 20.8x, compared with 29.0x to
30.6x for Unitog based on a Merger value of $36.00 to $38.00.
    
                                      -32-
<PAGE>   40
 
By applying the mean and median ratios derived from the Comparable Company
analysis to the historical and projected operating results of Unitog, Unitog's
implied equity value per share was calculated to be $15.20 to $29.10.
 
Analysis of Selected Merger and Acquisition Transactions. GAHS compared the
proposed Merger with selected comparable merger and acquisition transactions. No
transaction analyzed in the Comparable Transaction Analysis is identical to the
Merger. Accordingly, an analysis of the results of the foregoing necessarily
involves complex considerations and judgments concerning differences in
financial and operating characteristics of Unitog and Cintas and other factors
that could affect the acquisition value of the companies to which they are being
compared.
 
   
GAHS performed an analysis of five merger and acquisition transactions involving
textile products and services companies that occurred between April 1, 1996 and
January 7, 1999. GAHS's analysis focused on multiples of transaction value to
revenue because other income statement measures were not publicly available for
most of the acquired companies. For the five merger and acquisition transactions
analyzed, transaction value to revenue multiples ranged from 0.6x to 1.3x, with
a mean of 1.0x and a median of 1.1x, compared with a firm value to revenue
multiple of 1.6x to 1.7x for Unitog based on a Merger value of $36.00 to $38.00.
Based on the analysis of selected merger and acquisition transactions, Unitog's
implied equity value per share ranged from $17.40 to $26.30.
    
 
   
Acquisition Premiums Analysis. GAHS analyzed the premiums paid for 130 recent
mergers and acquisitions of publicly traded companies with transaction values
ranging from $300 to $600 million that were executed in 1997 and 1998. The mean
and the median premium paid over targets' stock prices four weeks before the
announcement date, one week before the announcement date, and one day before the
announcement date were 39.3% and 32.9%, 32.6% and 29.4%, and 27.8% and 22.5%,
respectively. The premium of Unitog Merger value ($36.00 to $38.00) to be paid
by Cintas over the Unitog closing price on November 30, 1998 (the last trading
day before Unitog's public announcement of its retention of investment bankers),
was 65.5% to 74.7%.
    
 
   
Historical Exchange Ratio Analysis. GAHS analyzed the historical exchange ratio
determined by comparing Unitog's Common Stock price and Cintas' Common Stock
price over a twelve-month period. During the twelve month period ended January
7, 1999, the exchange ratio reached a high of 0.5520 and a low of 0.3251. The
mean exchange ratio for this period was 0.4393 and the median was 0.4391. This
compares to an implied exchange ratio (Conversion Number) of 0.5227 to 0.5518,
based on a Unitog Merger value of $36.00 to $38.00 and a Cintas January 7, 1999
closing price, of $71.31.
    
 
Common Stock Trading History. GAHS' analysis of Unitog's and Cintas' Common
Stock trading history consisted of historical analyses of the trading prices and
volumes of Unitog and Cintas and the relative performance of Unitog, Cintas and
the S&P 500 Index.
 
   
GAHS' analysis considered the high and low closing prices for Unitog and Cintas
over the one year and three-year periods ended January 7, 1999. On December 30,
1998, Unitog's Common Stock reached a one-year high closing price of $29.13 and
on October 27, 1998, reached a one-year low closing price of $17.50. On October
17, 1996, Unitog's Common Stock reached a three year high closing price of
$32.06 and on October 27, 1998 reached a three year low closing price of $17.50.
On January 7, 1999, Cintas' Common Stock reached a one-year high closing price
of $71.31 and on February 5, 1998, reached a one year low closing price of
$40.00. On January 7, 1999, Cintas' common stock reached a three-year high
closing price of $71.31 and on January 15, 1996, reached a three-year low
closing price of $21.06. Calculating the Conversion Number based on the January
7, 1999 Cintas closing price of $71.31 and a $36.00 to $38.00 Unitog Merger
value results in an implied equity value per share of $37.28 to $39.35.
    
 
GAHS also analyzed the volume of shares traded at various prices. For Unitog's
Common Stock, the volume-weighted average price for the twelve months ending on
the trading day before the announcement that Unitog had hired investment bankers
to review strategic alternatives was $21.16. For Cintas, the volume-weighted
average price for the twelve months ending January 7, 1999 was $50.57.
 
                                      -33-
<PAGE>   41
 
GAHS was engaged to render an opinion to the Unitog Board in connection with the
Merger based upon its qualifications, expertise and reputation, including the
fact that GAHS is regularly engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, underwriting, sales and
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes.
 
   
Pursuant to a letter agreement with Unitog dated September 18, 1998, Goldsmith,
Agio, Helms and Company was entitled to a fee of $175,000 after delivering its
opinion. Upon consummation of the Merger, GAHS and its affiliate are entitled to
total cash compensation of approximately $3.6 million to $4.1 million, assuming
a Unitog Merger value of $36.00 to $38.00 and a Cintas Share Price of between
$52.00 and $66.43. GAHS and its affiliate received a monthly retainer of $10,500
since being engaged by Unitog. These retainers, as well as the $175,000 fee for
the opinion, will be credited against the total fee to be paid at closing.
Unitog has agreed to reimburse GAHS and its affiliate for out-of-pocket
expenses, including reasonable fees and expenses of counsel, and to indemnify
GAHS and its affiliate for liabilities and expenses arising out of the Merger or
transactions in connection therewith, including liabilities under federal
securities laws. The terms of the fee agreement with GAHS and its affiliate,
which are customary in transactions of this nature, were negotiated at arm's
length between Unitog and GAHS and its affiliate, and the Unitog Board was aware
of such arrangement.
    
 
George K. Baum & Company.
 
   
On January 9, 1999, George K. Baum & Company ("GKB") delivered certain of its
written analyses and its oral opinion to the Unitog Board of Directors to the
effect that, subject to the assumptions, procedures and limitations set forth
therein, as of such date, the proposed Merger Consideration to be received by
the holders of Unitog Common Stock pursuant to the Merger Agreement is fair from
a financial point of view to Unitog stockholders. The Merger Consideration is
subject to a possible environmental adjustment as outlined in Section 8.3 of the
Merger Agreement. (Pursuant to Section 8.3 of the Merger Agreement, the Unitog
share price of $38.00 is subject to adjustment based on specified environmental
investigation. Pursuant to Section 10.1 of the Merger Agreement, either party
may terminate the Merger Agreement if the aggregate adjustment to the Unitog
share price pursuant to Section 8.3 is more than $2.00. Therefore, the GKB
analysis addressed a Merger value for Unitog of $36.00 to $38.00). No
limitations were imposed by Unitog's Board of Directors on GKB with respect to
the investigation made or the procedures followed by it in rendering its
opinion.
    
 
A copy of GKB's opinion dated January 9, 1999, which sets forth the assumptions
made, matters considered, and limits on the review taken, is attached as
Appendix C to this Proxy Statement/Prospectus and is incorporated herein by
reference. Unitog stockholders are urged to read the GKB opinion in its
entirety. The description of the GKB opinion set forth herein is qualified in
its entirety by reference to the full text of such opinion. The GKB opinion is
rendered for the benefit and use of the Board of Directors of Unitog in
connection with the Board's consideration of the Merger and does not constitute
a recommendation to any holder of Unitog Common Stock as to how such stockholder
should vote with respect to the Merger.
 
In connection with its opinion, GKB reviewed, among other things, the Merger
Agreement; certain publicly available business and financial information
relating to Unitog and Cintas including Unitog's and Cintas' recent Annual
Reports, Forms 10-K, Forms 10-Q, and other filings with the Securities and
Exchange Commission ("SEC"); and certain internal financial analyses and
forecasts prepared by Unitog's management. GKB also has held discussions with
members of senior management of Unitog regarding the past and current business
operations, financial condition and future prospects of Unitog. In addition, GKB
reviewed the reported price and trading activity for Unitog Common Stock and
Cintas Common Stock, compared certain publicly available financial and stock
market information for Unitog with similar information for Cintas and certain
other companies that GKB believed to be comparable in certain respects to Unitog
and Cintas, reviewed the financial terms of certain business combinations that
GKB deemed to be similar to the Merger, reviewed certain recent historical data
relating to premiums paid in mergers and acquisitions of publicly traded
companies, and performed such other studies and analyses as GKB deemed
appropriate.
 
In preparing its opinion, GKB relied upon and assumed the accuracy and
completeness of all the financial and other information that was publicly
available or provided to GKB by or on behalf of Unitog and Cintas, and was not
engaged to independently verify any such information. GKB did not undertake nor
did it obtain any
 
                                      -34-
<PAGE>   42
 
independent evaluations or appraisals of any of Unitog's or Cintas' assets,
properties, or liabilities, nor did GKB make any physical inspection of the
properties or assets of Unitog or Cintas. GKB has assumed that the Merger will
be accounted for as a pooling of interests in accordance with GAAP and that such
Merger qualifies for such accounting treatment under GAAP. GKB has also assumed
that the Merger will constitute a tax-free reorganization pursuant to the Code.
GKB was not engaged to independently verify any legal and accounting matters
relative to the Merger Agreement.
 
GKB's analysis and opinion were prepared for the information and assistance of
the Board of Directors of Unitog in connection with its consideration of the
Merger and such opinion does not constitute a recommendation as to how any
holder of Unitog Common Stock should vote with respect to such transaction.
GKB's opinion necessarily is based on the conditions and circumstances as they
existed on January 9, 1999 and can be evaluated as of such date; events
occurring after the date of the opinion could materially affect the assumptions
used in preparing the opinion. GKB was not asked to, nor did it, express an
opinion as to the relative merits of the Merger as compared to any alternative
business strategies that might exist for Unitog or the effect of any other
transaction in which Unitog might engage.
 
The following is a summary of the principal analyses performed by GKB and
reported to the Unitog Board.
 
Common Stock Performance. GKB's analysis of Unitog's and Cintas' common stock
performance consisted of a historical analysis of the relative trading prices of
Unitog, Cintas, the S&P 500 Index, and a customized index of comparable textile
rental companies including G&K Services, Inc., UniFirst Corporation and Angelica
Corporation. GKB believes that the indexed companies were comparable to Unitog
and Cintas in terms of products and services offered, markets served and
prospects. During the three year period ending January 7, 1999, Unitog
underperformed both the S&P 500 Index and the comparable company index by 84.5%
and 26.2%, respectively. During the same period, Cintas outperformed both the
S&P 500 Index and the comparable company index by 117.0% and 175.3%,
respectively.
 
   
GKB's analysis also considered the high and low closing prices for Unitog Common
Stock and Cintas Common Stock over the one-year and three-year periods ended
January 7, 1999. On December 30,1998, Unitog Common Stock reached a one-year
high closing price of $29.13 and on October 27, 1998, reached a one-year low
closing price of $17.50. On October 17, 1996, Unitog Common Stock reached a
three-year high closing price of $32.06 and on October 27, 1998, reached a
three-year low closing price of $17.50. These compare to the implied price for
Unitog of $37.28 to $39.35, based on the Conversion Number, using the January 7,
1999 Cintas closing price of $71.31, and a Merger value for Unitog of $36.00 to
$38.00. On January 7, 1999, Cintas' Common Stock reached a one-year high closing
price of $71.31 and on February 5, 1998, reached a one-year low closing price of
$40.00. On January 7, 1999, Cintas Common Stock reached a three-year high
closing price of $71.31 and on January 15, 1996, reached a three-year low
closing price of $21.06.
    
 
GKB also analyzed the volume of shares traded at various prices. For Unitog
Common Stock, the volume-weighted average price for the twelve months ending
November 27, 1998, on the trading day before the announcement, was $21.16. This
period was chosen to exclude shares traded after the announcement that Unitog
had hired investment bankers to review strategic alternatives. For Cintas, the
volume-weighted average price for the twelve months ending January 7, 1999 was
$50.57.
 
   
Historical Exchange Ratio Analysis. GKB's analysis of the historical exchange
ratio between Unitog Common Stock and Cintas Common Stock consisted of a twelve
month comparison. During the twelve-month period ended January 7, 1999, the
exchange ratio reached a high of 0.5520 and a low of 0.3251. The mean exchange
ratio for this period was 0.4393 and the median was 0.4391. This compares to an
implied exchange ratio (Conversion Number of 0.5227 to 0.5508), based on a
Merger value for Unitog of $36.00 to $38.00 and a Cintas January 7, 1999 closing
price of $71.31.
    
 
Discounted Cash Flow Analysis. GKB performed a discounted cash flow analysis of
the unlevered free cash flows of Unitog's projected five-year financial
performance estimates, which were prepared by Unitog's management. For the
purposes of this analysis, GKB applied a weighted average cost of capital of
10%, 10.5% and 11%. GKB calculated terminal values both by applying an EBITDA
multiple of 7.0x to the projected EBITDA of Unitog in fiscal year 2004 and by
applying a 5% terminal growth rate to the projected free cash flow
                                      -35-
<PAGE>   43
 
in fiscal year 2004. From these assumptions, GKB calculated per share equity
values for Unitog ranging from $23.56 to $30.58 with an average value of $27.18.
 
Comparable Company Analysis. No company utilized in the comparable company
analysis is identical to Unitog or Cintas. Accordingly, an analysis of the
results of the foregoing necessarily involves complex considerations and
judgments concerning the differences in financial and operating characteristics
and other factors that could affect the public trading value of Unitog, Cintas
and other publicly traded companies that GKB deemed comparable to Unitog and
Cintas. Mathematical analysis is not in itself a meaningful method of using
comparable transaction data.
 
GKB analyzed selected financial, operating and stock market data of Unitog,
Cintas and three companies deemed by GKB to be reasonably comparable to Unitog
and Cintas in terms of products and services offered, markets served and
prospects: G&K Services, Inc., UniFirst Corporation and Angelica Corporation
(the "Comparable Companies").
 
   
GKB examined certain publicly available financial and market trading data of the
Comparable Companies including firm value (equity value plus total net debt) as
a multiple of the latest-twelve-month ("LTM") revenues, EBITDA and EBIT and
price to earnings ratios ("P/E's") based on estimated and projected Earnings Per
Share ("EPS") for the calendar years ending 1998 and 1999. For purposes of
computing pricing multiples for Unitog implied in the Merger, the value of
Unitog was assumed to be $36.00 to $38.00 per share. Latest-twelve-months
financial data for Unitog incorporates management's projection for the twelve
months ended January 31, 1999, excluding the results from certain operations
which were sold during this period.
    
 
   
This analysis resulted in (i) a range of multiples of firm value to LTM revenues
of 0.5x to 2.5x with a mean of 1.4x and a median of 1.1x for the Comparable
Companies, compared to 1.6x to 1.7x for Unitog under the Merger, (ii) a range of
multiples of firm value to LTM EBITDA of 5.9x to 11.8x with a mean of 7.9x and a
median of 5.9x, compared to 1.3x to 10.7x for Unitog under the Merger, (iii) a
range of firm value to LTM EBIT of 8.8x to 17.5x with a mean of 12.0x and a
median of 9.7x, compared to 17.7x to 18.5x for Unitog under the Merger, (iv) a
range of multiples of 1998E EPS of 13.0x to 30.7x with a mean of 20.9x and a
median of 19.0x, compared to 29.0x to 30.6x for Unitog under the Merger, (v) a
range of multiples of 1999E EPS of 12.6x to 25.6x with a mean of 18.0x and a
median of 15.7x, compared to 26.0x to 27.4x for Unitog under the Merger. EPS
estimates for the Comparable Companies were based on the Institutional Broker
Estimate System (IBES).
    
 
Comparable Transaction Analysis. No merger or acquisition transaction utilized
in the comparable transaction analysis is identical to the Merger. Accordingly,
an analysis of the results of the foregoing necessarily involves complex
considerations and judgments concerning differences in financial and operating
characteristics of Unitog and Cintas and other factors that could affect the
acquisition value of the companies to which they are being compared.
Mathematical analysis is not in itself a meaningful method of using comparable
transaction data.
 
   
GKB performed an analysis of five merger and acquisition transactions involving
companies in the textile services industry that occurred between April 1, 1996
and January 7, 1999. Multiples of firm value to revenue were calculated for
these transactions, which resulted in a range of multiples from 0.6x to 1.3x,
with a mean of 1.0x and a median of 1.1x, compared with a firm value to revenue
multiple of 1.6x to 1.7x for Unitog based on a Merger value of $36.00 to $38.00
per share.
    
 
   
Acquisition Premiums Analysis. GKB analyzed the premiums paid for 130 recent
mergers and acquisitions of publicly traded companies with transaction values in
the range of $300 million to $600 million that were executed between January 7,
1997 and January 7, 1999. The mean and median premium paid over the targets'
stock prices four weeks before the announcement date, one week before the
announcement date and one day before the announcement date were 39.3% and 32.9%,
32.6% and 29.4%, and 27.8% and 22.5%, respectively. The premium of Unitog Merger
value ($36.00 to $38.00) over the Unitog closing price on November 30, 1998, the
last trading day before the announcement of the hiring of investment bankers to
evaluate strategic alternatives, was 65.5% to 74.7%.
    
 
The summary set forth above does not purport to be a complete description of the
analyses performed by GKB, but describes, in summary form, the principal
elements of the analyses performed by GKB in arriving at its
 
                                      -36-
<PAGE>   44
 
opinion. The preparation of a fairness opinion involves 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,
such an opinion is not readily susceptible to summary description. GKB did not
form a conclusion as to whether any individual analysis, considered in
isolation, supported or failed to support an opinion as to fairness from a
financial point of view. Rather, in reaching its conclusion, GKB considered the
results of the analyses in light of each of the other analyses and the other
information available and ultimately reached its opinion based on the results of
the analyses and other information taken as a whole. GKB did not place
particular reliance or weight on any individual factor, but instead concluded
that, taken as a whole, the analyses and other information supported its
opinion. Accordingly, notwithstanding the separate factors summarized above, the
analyses must be considered as a whole, and selecting portions of the analysis
and the factors considered by GKB, without considering all analyses and factors,
could create an incomplete or misleading view of the evaluation process
underlying GKB's opinion. The analyses performed by GKB are not necessarily
indicative of actual values or future results, which may be materially more or
less favorable than suggested by such analyses.
 
GKB was selected to render an opinion in connection with the Merger based upon
its knowledge and familiarity with Unitog and its industry as well as GKB's
qualifications, expertise and reputation, including the fact that it is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, underwriting, sales and distributions of listed
and unlisted securities, private placements and valuations for corporate and
other purposes.
 
   
Pursuant to a letter agreement between Unitog and GKB dated September 18, 1998,
GKB was entitled to a fee of $75,000 upon delivering its opinion. Upon
consummation of the Merger, GKB is entitled to total cash compensation of
approximately $1.54 million to $1.75 million, assuming a Unitog Merger value of
$36.00 to $38.00 and a Cintas Share Price between $52.00 and $66.43. GKB has
received a monthly retainer of $4,500 since being engaged by Unitog. These
retainers, as well as the $75,000 fee for the opinion, will be credited against
the total fee to be paid at closing. Unitog has agreed to reimburse GKB for
out-of-pocket expenses, including reasonable fees and expenses of counsel, and
to indemnify GKB for liabilities and expenses arising out of the Merger or
transactions in connection therewith, including liabilities under federal
securities laws. The terms of the fee arrangement with GKB, which are customary
in transactions of this nature, were negotiated at arm's length between Unitog
and GKB, and the Unitog Board was aware of such arrangement.
    
 
GKB has previously rendered financial advisory and investment banking services
to Unitog for which it has received customary compensation. William D. Thomas, a
member of Unitog's Board of Directors, is a vice president of GKB and a director
and officer of George K. Baum Group, Inc., a holder of 661,870 shares of Unitog
Common Stock. G. Kenneth Baum, also a member of Unitog's Board of Directors, is
an employee of GKB and a director, officer and shareholder of George K. Baum
Group, Inc. See "Interests of Certain Persons in the Merger -- Affiliation with
Financial Advisor". In the ordinary course of securities business, GKB and its
affiliates may hold or actively trade the securities of Unitog or Cintas for its
own account and for the accounts of its customers and, accordingly, may at any
time hold a long or short position in such securities. Additionally, GKB makes a
market in Unitog Common Stock on the Nasdaq National Market.
 
FEDERAL INCOME TAX CONSEQUENCES
 
The following discussion is a summary of the material federal income tax
consequences of the Merger to holders of Unitog Common Stock. The discussion is
based on the Code, proposed, temporary and final Treasury regulations
promulgated thereunder, published administrative rulings and pronouncements and
judicial decisions in effect as of the date of this Proxy Statement/Prospectus,
all of which are subject to change, possibly with retroactive effect.
 
This discussion is for general information only and does not address every
aspect of the federal income tax laws that may be relevant to certain Unitog
stockholders in light of their personal investment circumstances, nor does it
address the effects of any state, local or foreign tax laws on the Merger. The
tax treatment of a Unitog stockholder may vary depending upon the stockholder's
particular situation, and certain stockholders (including, for example,
insurance companies, tax-exempt organizations, financial institutions and
broker-dealers, and individuals who received Unitog Common Stock pursuant to the
exercise of employee stock options or otherwise as
 
                                      -37-
<PAGE>   45
 
compensation) may be subject to special rules not discussed below. In addition,
the discussion relates to persons who hold Unitog Common Stock as capital
assets.
 
Consummation of the Merger is conditioned upon the receipt by Cintas of an
opinion from Keating, Muething & Klekamp, P.L.L., its counsel, and by Unitog of
an opinion from Bryan Cave LLP, as its special tax counsel, to the effect that
the Merger will constitute a reorganization within the meaning of Section 368 of
the Internal Revenue Code. These opinions will be based on facts existing at the
time the Merger becomes effective and on certain representations as to factual
matters made by Cintas and Unitog. If the representations are incorrect in any
material respects, it could jeopardize the conclusions reached in the opinions.
Neither Cintas nor Unitog is aware of any facts or circumstances which would
cause any of its representations made to counsel to be untrue or incorrect in
any material respect. An opinion of counsel is not binding on the Internal
Revenue Service or the courts. Further, no ruling has been or will be sought
from the Internal Revenue Service as to the federal income tax consequences of
the Merger. As a result, the Internal Revenue Service may disagree with the
federal income tax consequences discussed below.
 
Based on the opinions discussed above, the material federal income tax
consequences that will result from the Merger are:
 
     1. A Unitog stockholder will not recognize any income, gain or loss as a
        result of the receipt of Cintas Common Stock pursuant to the Merger,
        except for cash received in lieu of a fractional share of Cintas Common
        Stock.
 
     2. The tax basis of a Unitog stockholder in the Cintas Common Stock
        received pursuant to the Merger, including any fractional share interest
        in Cintas Common Stock for which cash is received, will equal the Unitog
        stockholder's tax basis in the Unitog Common Stock exchanged.
 
     3. The holding period of a Unitog stockholder for the Cintas Common Stock
        received pursuant to the Merger will include the holding period of the
        Unitog Common Stock surrendered.
 
     4. A Unitog stockholder who receives cash in lieu of a fractional share
        interest in Cintas Common Stock pursuant to the Merger will be treated
        as if the fractional shares were actually issued by Cintas as part of
        the exchange and then redeemed by Cintas for cash. These cash payments
        will be treated as having been received in exchange for the redeemed
        fractional share interests under Section 302(a) of the Code. The receipt
        of such cash payments will generally result in capital gain or loss in
        an amount equal to the difference between the amount of cash received
        and the basis of the fractional Cintas Common Stock.
 
     5. No income, gain or loss will be recognized by Unitog, Cintas or its
        subsidiary as a result of the Merger.
 
The foregoing discussion is only a summary and is not a complete analysis or
listing of all potential tax effects relevant to a decision whether to vote in
favor of approval of the Merger Agreement. You are urged to consult your own tax
advisor in determining the federal, state, local and foreign income tax
consequences, and any other tax consequences, of the Merger to you.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
All shares of Cintas Common Stock received by Unitog stockholders in the Merger
will be freely transferable. However, shares of Cintas Common Stock received by
any person who is deemed to be an "affiliate" (as such term is defined under the
Securities Act of 1933) of Unitog prior to the Merger or of Cintas after the
Merger may be resold by them only in compliance with the volume and
manner-of-sale requirements of Rules 144 and 145 under the Securities Act.
Affiliates of Cintas will be governed by additional provisions of Rule 144.
Affiliates of Cintas or Unitog 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 such party as well as principal
stockholders of such party.
 
                                      -38-
<PAGE>   46
 
CERTAIN EFFECTS OF THE MERGER
 
Cintas' subsidiary will be merged with and into Unitog, with Unitog surviving
the Merger and becoming a wholly-owned subsidiary of Cintas. Stockholders of
Unitog will become stockholders of Cintas. As of the effective time of the
Merger, Unitog Common Stock will no longer be traded on Nasdaq, and the
registration of Unitog Common Stock under the Securities Exchange Act of 1934
will be terminated.
 
At the effective time of the Merger, the certificate of incorporation and bylaws
of Unitog shall be amended and Unitog's board of directors and executive
officers will become composed of individuals designated by Cintas who are not
expected to include current directors or executive officers of Unitog.
 
CONDUCT OF BUSINESS IF MERGER NOT CONSUMMATED
 
If the Merger is not consummated, Unitog will continue its current operations.
However, for reasons discussed under the caption, "THE MERGER -- Background of
the Merger," Unitog may continue to explore strategic alternatives, including a
business combination or sale of Unitog.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
In considering the recommendation of the Unitog Board with respect to the
Merger, stockholders of Unitog should be aware that executive officers and
directors of Unitog have certain interests in the Merger, described below, that
are separate from and in addition to the interests of stockholders of Unitog
generally. The Unitog Board was aware of these interests and took them into
account in approving the Merger Agreement and the transactions contemplated
thereby.
 
Severance Agreements for Unitog Executive Officers
 
   
Unitog's executive officers are parties to severance agreements with Unitog
which provide that if their employment is terminated within two years after the
Merger for reasons other than misconduct, disability or death or they elect to
resign because of (i) a material adverse change of their responsibilities,
authority, status, position, offices, titles, duties or reporting requirements,
(ii) an adverse change in annual compensation or benefits or (iii) a requirement
to relocate in excess of fifty miles from their current employment, they shall
receive, in addition to all compensation due and payable to or accrued as of the
date of the termination, a lump sum payment. The lump sum payable in such
circumstances to Unitog's Chairman, President and Chief Executive Officer,
Randolph K. Rolf, would equal 2.99 times his "base amount" of compensation (as
defined by Section 280(b)(3) of the Code), which is $313,817, and would result
in a lump sum payment of $938,313. The lump sum payable in such circumstances to
three other Unitog executive officers, Terence C. Shoreman, J. Craig Peterson
and Robert M. Barnes, is equal to two times their "annual compensation" (as
defined in their severance agreements), which is $325,094, $274,402 and
$184,503, respectively, and would result in lump sum payments (subject to
limitations relating to Code Section 280G applicable to Messrs. Shoreman and
Barnes) of $502,250, $548,804 and $319,322, respectively. The lump sum payable
in such circumstances to the remaining Unitog executive officers, G. Jay
Arrowsmith and Ronald J. Harden, is equal to their "annual compensation" (as
defined in their severance agreements), which is $179,601 and $136,163,
respectively, and would result in lump sum payments of such amounts.
    
 
Stock Option Plans
 
   
Under the terms of the Merger Agreement, all options outstanding and held by
executive officers and directors of Unitog, under the Unitog 1997 Stock Option
Plan vest immediately upon the consummation of the Merger which would result in
vesting of options for 21,750 Unitog shares held by executive officers and
directors. All options outstanding (including those held by executive officers
of Unitog) under the Unitog 1992 Stock Option Plan vest in full if the
participant's employment is voluntarily or involuntarily terminated within one
year after the Merger, which could result in vesting of options for 12,125
Unitog shares for the executive officers; additionally, to such executive
officers such options would be settled by the payment to each participant of an
amount equal to the excess, if any, of the aggregate fair market value of the
shares subject thereto on the date of Merger over the exercise price of the
option which, based upon an assumed fair market value of $37.87, could result in
maximum
    
                                      -39-
<PAGE>   47
 
   
aggregate payments of approximately $187,080 to the executive officers with
respect to previously unvested options.
    
 
Affiliation with Financial Advisor
 
   
Unitog directors G. Kenneth Baum and William D. Thomas have certain affiliations
with George K. Baum & Company ("GKB"), one of Unitog's financial advisors with
respect to the Merger. Mr. Baum is an employee and Mr. Thomas is a vice
president of GKB and both Mr. Baum and Mr. Thomas are affiliated with George K.
Baum Group, Inc., which holds 661,870 shares of Unitog Common Stock. In
connection with GKB's role as a financial advisor in the Merger, Unitog has
agreed to pay GKB a fee of approximately $1.54 million to $1.75 million, all of
which except for $125,000 is contingent upon consummation of the Merger. See
"THE MERGER -- Opinions of Financial Advisors".
    
 
Outside Director Fee/Stock Program
 
Each outside director of Unitog, pursuant to the Outside Director Fee/Stock
Program, is given the opportunity to elect to take all or a portion of their
director fees in Unitog stock rather than in cash. Shares earned in a calendar
year are issued after the end of the current calendar year. All six of Unitog's
outside directors participate in the program and one former director has
unissued shares accrued for his benefit under the Plan. The Merger would
constitute a "change of control" under such program, and would cause all accrued
but unissued shares to be issued immediately upon completion of the Merger. The
total number of shares of Unitog Common Stock subject to accelerated issuance
under such program is 910 shares.
 
Directors' and Officers' Indemnification and Insurance
 
The Merger Agreement provides that, after the Merger, Unitog, as the surviving
corporation, is obligated to indemnify each present and former director and
officer of Unitog and /or its subsidiaries against any liabilities arising out
of actions or omissions in their capacity as such at or prior to the effective
time of the Merger, to the full extent as permitted under applicable law. Unitog
is also obligated to maintain directors' and officers' liability insurance,
comparable to that maintained prior to the Merger for five years after the
Merger.
 
REGULATORY FILINGS AND APPROVALS
 
Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission, the Merger may not be consummated until notifications have been
given and certain information has been furnished to the FTC and the Antitrust
Division of the Department of Justice (the "Antitrust Division"), and specified
waiting period requirements have been satisfied. Cintas and Unitog each filed
premerger notification and report forms with the FTC and Antitrust Division on
January 26, 1999, and early termination of the waiting period was granted on
February 5, 1999. At any time before or after consummation of the Merger, and
notwithstanding the satisfaction of the HSR Act requirements, the FTC or the
Antitrust Division or any state could take action under the federal or state
antitrust laws to seek to enjoin consummation of the Merger. Private parties may
also seek to take legal action under the antitrust laws. Based on the
information available to them, each of Cintas and Unitog believes that the
Merger can be effected in compliance with federal and state antitrust laws.
However, there can be no assurance that a challenge to the Merger on antitrust
grounds will not be made or that, if such challenge were made, Cintas and Unitog
would prevail.
 
                              THE MERGER AGREEMENT
 
The description of the Merger Agreement set forth below is not complete. For
full information, you should read the Merger Agreement, a copy of which is
attached to this Proxy Statement/Prospectus as Appendix A.

TERMS OF THE MERGER
 
The Merger. A subsidiary of Cintas will merge with and into Unitog, the separate
corporate existence of the subsidiary will cease, and Unitog will continue as
the surviving corporation and will be a wholly-owned subsidiary of Cintas.
 
Effective Time. As promptly as practicable after the satisfaction or waiver of
the conditions set forth in the Merger Agreement, Cintas and Unitog will
complete the Merger by filing a Certificate of Merger with the Secretary of
State of Delaware (the time of such filing being the "Effective Time").
 
   
Conversion of Unitog Common Stock in the Merger. At the Effective Time, shares
of Unitog Common Stock issued and outstanding immediately prior to the Effective
Time (excluding shares held by Cintas or any subsidiary of Cintas) will be
converted into the right to receive validly issued, fully paid and nonassessable
shares of Cintas Common Stock. The Conversion Number is determined by dividing
the "target" Unitog Share Price ("Unitog Share Price") of $38 (reduced to $37.87
for certain environmental liability estimates described below) by the Cintas
Share Price, subject to certain adjustments to the Cintas Share Price if it is
less than $52 or more than $66.43.
    
 
Effect of Cintas Share Price Fluctuation
 
   
     - If the Cintas Share Price is greater than $66.43, the Cintas Share Price
       used to determine the Conversion Number is deemed to be $66.43 plus
       one-half of the amount by which the Cintas share price is greater than
       $66.43 (and thereby results in a value of more than $37.87 per Unitog
       share based upon the Cintas Share Price).
    
 
   
     - If the Cintas Share Price is equal to or between $52 and $66.43, each
       Unitog share would be exchanged for Cintas Common Stock with a $37.87
       value (based upon the Cintas Share Price).
    
 
   
     - If the Cintas Share Price is less than $52, the Cintas share price used
       to determine the Conversion Number is deemed to be $52 (and thereby
       results in a value of less than $37.87 per Unitog share based on the
       Cintas Share Price), but in such event the Unitog Board has the right to
       terminate the Merger Agreement as discussed under
       " -- Termination -- Conditions to Termination" below. The Unitog Board is
       not required to exercise this right and does not currently intend to
       resolicit stockholder approval should it decide not to exercise such
       right. THEREFORE, UNITOG STOCKHOLDERS COULD RECEIVE MERGER CONSIDERATION
       VALUING THEIR SHARES OF UNITOG COMMON STOCK AT LESS THAN $37.87 PER
       SHARE.
    
 
Effect of Environmental Liability Reduction
 
     - The "target" Unitog Share Price of $38 was subject to reduction if
       certain environmental liability estimates, determined in accordance with
       the Merger Agreement on an after tax, net present value basis, exceeded
       $570,000 (any such reduction, an "Environmental Estimate Reduction"). The
       Environmental Estimate Reduction reduces the "target" $38 Unitog Share
       Price by $0.01 for each $100,000 of such excess, subject to certain
       conditions.
 
   
     - The Environmental Estimate Reduction has been determined to be $0.13 per
       share, thereby reducing the $38 Unitog Share Price to $37.87.
    
 
Assumption of Outstanding Stock Options. After the Effective Time, each
outstanding stock option of Unitog Common Stock by virtue of the Merger
Agreement will become an option to acquire the number of shares of Cintas Common
Stock equal to the number of shares of Unitog Common Stock subject to the option
multiplied by the Conversion Number (rounded up or down to the nearest whole
share). The price per share of each option will equal the option price per share
of Unitog Common Stock subject to the option in effect immediately before the
Effective Time divided by the Conversion Number (rounded up to the nearest full
cent).
 
Fractional Shares. No fractional shares of Cintas Common Stock will be issued in
the Merger. Instead, Cintas will pay each Unitog stockholder who would otherwise
have been entitled to a fractional share of Cintas Common Stock an amount equal
to such fraction multiplied by the Cintas Share Price.
 
                                      -41-
<PAGE>   49
 
EXCHANGE OF CERTIFICATES
 
Exchange Agent. The Fifth Third Bank, Cincinnati, Ohio, the transfer agent for
Cintas Common Stock, will act as exchange agent for the Merger.
 
Exchange Procedures. As soon as reasonably practicable after the Effective Time,
Cintas will instruct the Exchange Agent to mail to each record holder of Unitog
Common Stock at the Effective Time a letter of transmittal and instructions for
exchanging certificates representing Unitog Common Stock for certificates
evidencing Cintas Common Stock. You will have to follow the instructions and
surrender your certificates for Unitog Common Stock, together with the properly
executed letter of transmittal, and any other required documents, to the
Exchange Agent. You then will be entitled to receive (i) certificates for that
number of whole shares of Cintas Common Stock which you have the right to
receive in the Merger, (ii) any dividends or other distributions on the Cintas
Common Stock declared or made after the Effective Time to which you may be
entitled, and (iii) cash in respect of any fractional share of Cintas Common
Stock. Until so surrendered, each outstanding certificate that, prior to the
Effective Time, represented shares of Unitog Common Stock will be deemed, for
all corporate purposes other than the payment of dividends, and subject to the
payment of cash in lieu of fractional shares, to evidence the ownership of the
number of whole shares of Cintas Common Stock into which such shares of Unitog
Common Stock have been converted.
 
Distributions With Respect to Unexchanged Shares. If any dividends or other
distributions are declared or made after the Effective Time on shares of Cintas
Common Stock, you will not receive them until you surrender your Unitog stock
certificates. When you do surrender your certificates, Cintas will pay you,
without interest, any dividends or other distributions with a record date after
the Effective Time previously paid to holders of Cintas Common Stock.
 
Transfers of Ownership. If you want any certificate for shares of Cintas Common
Stock to be issued in a name other than that in which the Unitog certificate
surrendered in exchange is registered, your Unitog certificate must be properly
endorsed and otherwise in proper form for transfer. You also must pay to Cintas
or its agent any resulting transfer or other tax, or establish to the
satisfaction of Cintas that such tax has been paid or is not payable.
 
Escheat and Withholding. Neither Cintas nor Unitog will be liable to you for any
Merger Consideration delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law. Cintas or the Exchange Agent will
deduct from the Merger Consideration paid to you any amounts that Cintas or the
Exchange Agent is required to withhold under any provision of federal, state,
local or foreign tax law.
 
Lost, Stolen or Destroyed Certificates. The Exchange Agent will issue Cintas
Common Stock in exchange for a lost, stolen or destroyed Unitog stock
certificate upon receipt of an affidavit of that fact by the owner of the
certificate. However, Cintas will require you to deliver a reasonable indemnity
bond against any claim that may be made against Cintas or the Exchange Agent
with respect to a certificate alleged to have been lost, stolen or destroyed.
 
DETAILED INSTRUCTIONS, INCLUDING A TRANSMITTAL LETTER, WILL BE MAILED TO UNITOG
STOCKHOLDERS PROMPTLY FOLLOWING THE EFFECTIVE TIME EXPLAINING HOW TO EXCHANGE
UNITOG CERTIFICATES FOR CINTAS CERTIFICATES. YOU SHOULD NOT SEND IN YOUR UNITOG
STOCK CERTIFICATES UNTIL YOU RECEIVE YOUR TRANSMITTAL LETTER.
 
REPRESENTATIONS AND WARRANTIES
 
The Merger Agreement contains various representations and warranties of Unitog
and of Cintas. Those relate, among other things, to the following matters
(which, in certain cases, are subject to specified exceptions):
 
     1. Corporate Status; Capital Stock. The organization, good standing,
qualification and capitalization are as described in the Merger Agreement and,

of Unitog's subsidiaries, or Cintas and its subsidiaries, as the case may be,
which is material to Unitog and its subsidiaries, or Cintas and its
subsidiaries, taken as a whole, as the case may be, and except as disclosed to
the other party as described in the Merger Agreement (a "Material Adverse
Effect");
 
     4. Accuracy of Reports and Financial Statements. Each party has filed its
required reports and documents with the Securities and Exchange Commission.
There are no material misstatements contained in those filings. Certain
financial statements included in those filings comply with applicable rules and

and there are no undisclosed liabilities that could reasonably be expected to
have a Material Adverse Effect;
 
     5. Conduct of Business. Since the beginning of fiscal year 1999 (as of the

conducted its business in the ordinary course and there has been an absence of
certain changes or events, including the occurrence of a Material Adverse
Effect;
 
     6. Absence of Material Untrue Statements. There are no material untrue
statements in this Proxy Statement/Prospectus or the Registration Statement
filed with the Securities and Exchange Commission of which it is a part; and
 
     7. Other Matters. The Merger Agreement also includes representations and
warranties dealing with employee relations, benefit plans, title to properties
owned by Unitog, compliance with laws, the absence of litigation that would have
a Material Adverse Effect, insurance, intellectual property rights, contracts,
taxes, the validity and standing of any required permits and authorizations,
compliance with environmental laws, maintenance of books and records, Year 2000
compliance, state takeover statutes and customers.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
Conduct of Business of Cintas and Unitog. Prior to the Effective Time, each of
Cintas and Unitog will conduct its business and day to day operations in the
ordinary and usual course of business, consistent with past practice, and will
seek to preserve intact its business organization and goodwill and keep in full
force and effect all of its material rights. Specifically, the Merger Agreement
provides that neither Cintas nor Unitog will do the following without the
consent of the other:
 
     1. Amend its Certificate or Articles of Incorporation or Bylaws;
 
     2. Except under its employee and director stock option plans and, with
respect to Cintas only, except in connection with acquisitions of stock or
assets of other businesses, issue any of its capital stock or securities
convertible or exchangeable into its capital stock;
 
     3. Except under existing employee benefit plans, redeem, repurchase or
acquire any of its outstanding capital stock;
 
     4. Change its capital stock or declare, set aside or pay any dividend or
distribution, except with respect to regular dividends consistent with past
practice;
 
     5. Take any action or fail to take any action that would prevent or impede
the Merger from qualifying for "pooling of interests" accounting treatment or
from qualifying as a tax-free reorganization under the Code;
 
     6. Take any action that would render a representation or warranty in the
Merger Agreement to be untrue;
                                      -43-
<PAGE>   51
 
     7. Take any action that would cause any condition of the Merger Agreement
to not be satisfied; or
 
     8. Propose to or announce an intention to do any of the foregoing.
 
Limitations on Conduct of Business Applicable to Unitog. Unitog will not,
without the prior written consent of Cintas:
 
     1. Except for the Merger, adopt a plan of liquidation, dissolution or
merger;
 
     2. Make new grants or awards under its benefit plans or increase the
salaries of directors, officers or key employees (other than customary increases
to key employees in amounts not in excess of 5%);
 
     3. Except in the ordinary course of business, consistent with past
practice, incur or guarantee debt or make loans, advances or capital
contributions to any person other than a wholly-owned subsidiary;
 
     4. Make any acquisition, through merger, consolidation or otherwise;
 
     5. Make any capital expenditure or commitment in excess of $100,000; or
 
     6. Purchase any shares of Unitog Common Stock under any current stock
repurchase plan or otherwise purchase any Unitog Common Stock.
 
No Solicitation. The Merger Agreement provides that Unitog will not, directly or
indirectly, take any actions designed to facilitate a proposal from any person
to acquire 51% or more of Unitog's common stock or Unitog's assets or any
proposal or offer for a merger or other business combination with Unitog, other
than the Merger (an "Acquisition Proposal"), or participate in discussions or
negotiations regarding an Acquisition Proposal. However, if the Board of
Directors of Unitog, after consultation with financial and legal advisors,
reasonably believes that it has received a bona fide proposal which is more
favorable financially to Unitog than the Merger (a "Superior Proposal"), Unitog
may furnish information and access to the person submitting the Superior
Proposal and may negotiate with such person.
 
ADDITIONAL AGREEMENTS
 
Access to Information; Confidentiality. Upon reasonable notice and subject to
any other agreement by which it is bound, each of Unitog and Cintas will afford
the other reasonable access to its properties, books, contracts, commitments and
records and will furnish promptly to the other all information concerning its
business, properties and personnel as the other may reasonably request. Each
party has agreed to keep such information confidential.
 
Indemnification; Insurance. After the Effective Time, Cintas will, and will
cause Unitog to, indemnify and hold harmless each present and former director of
Unitog or any of its subsidiaries against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of or pertaining to matters existing or occurring prior to the Effective
Time. No indemnification is required where a judgment or final adjudication
established that his or her acts or omissions (i) were committed in bad faith or
were the result of active and deliberate dishonesty and were material to the
cause of action or (ii) arose out of, were based upon or were attributable to
the gaining in fact of any financial profit or other advantage to which he or
she was not entitled. Unitog will maintain directors' and officers' liability
insurance comparable to that maintained prior to the Merger for five years after
the Merger.
 
Employees. Except as stated, for two years after the Effective Time, Cintas will
maintain all programs and benefits for employees of Unitog and its subsidiaries
who are not subject to collective bargaining. Such programs and benefits will be
on terms no less favorable in the aggregate than those of Unitog at the
Effective Time. Cintas will recognize the length of service of Unitog employees
with Unitog or its subsidiaries with respect to all of Cintas' benefit plans
except for the Cintas Partners' Plan. Cintas and Unitog will also honor and
assume all stated retention programs, severance plans and noncompetition and
severance agreements of Unitog.

reasonable efforts to consummate as promptly as practicable the transactions
contemplated by the Merger Agreement, to obtain in a timely manner all necessary
waivers, consents and approvals and to effect all necessary registrations and
filings, and otherwise to satisfy or cause to be satisfied all conditions
precedent to their obligations under the Merger Agreement. In addition, each of
the parties has agreed to use its commercially reasonable efforts to cause the
Merger to qualify as a reorganization under the provisions of Section 368 of the
Code and will not (both before and after consummation of the Merger) take any
actions which to its knowledge could reasonably be expected to prevent the
Merger from so qualifying.
 
Treatment of Options. Options to purchase Unitog Common Stock become rights to
purchase shares of Cintas Common Stock as discussed under "-- Terms of the
Merger -- Outstanding Stock Options" above.
 
Accountants' Letters. Each of Unitog and Cintas will use its best efforts to
cause KPMG LLP and Ernst & Young LLP, respectively, to deliver letters to Cintas
and Unitog, respectively, covering such matters as are requested by Cintas or
Unitog, as the case may be, and as are customarily addressed in accountants'
"comfort" letters.
 
Pooling Accounting Treatment. Cintas and Unitog have each agreed not to take any
action that would reasonably be expected to adversely affect the ability of
Cintas to treat the Merger as a pooling of interests.

AMENDMENT AND WAIVER
 
The Merger Agreement may be amended in writing by the parties at any time prior
to the Effective Time. After approval of the Merger by the stockholders of

Unitog
 
Special meetings may be called by the Board of Directors or by stockholders
holding at least 10% of the outstanding common stock.
 
ANTI-TAKEOVER PROVISIONS
 
Cintas
 
The Cintas Articles require that a person acquiring 15% or more of Cintas'
outstanding common stock without prior Board approval must offer to purchase all
outstanding shares at the higher of the highest price paid by that person,
adjusted for a control premium, or the highest recent market price. The Cintas
Articles also provide that if a person acquires more than 15% of the stock, any
transaction in which that person is involved with Cintas, such as a merger or
sale of assets, requires approval by two-thirds of all disinterested shares.
Disinterested shares are all outstanding shares other than those owned by the
15% party. The Board of Directors may waive this provision. Washington law
provides that significant business transactions, such as mergers and sales of
more than 5% of assets, termination of more than 5% of employees, certain
issuances of shares, reclassifications and similar matters, cannot be effected
with a person who acquires 10% or more of the outstanding stock for a period of
five years after the acquisition of that position unless the 10% acquisition is
first approved by the Board of Directors.
 
                                      -48-

These provisions may make it more difficult for other persons, without prior
approval of Cintas' Board of Directors, to make a tender offer for acquisitions
of substantial amounts of Cintas' Common Stock or to initiate other takeover
attempts that shareholders might consider to be in their best interest.
 
Unitog
 
The Unitog Certificate requires the affirmative vote of at least two-thirds of
all classes of stock entitled to vote in an election of directors voting as one
class to approve mergers and similar transactions with persons who beneficially
own 5% or more of Unitog's outstanding shares.
 
Delaware corporate law prohibits business combinations with persons who acquire
15% or more of the outstanding voting stock without prior approval of the Board
of Directors for a period of three years after the date of acquisition. Business
combinations are mergers, sales of assets and other extraordinary corporate
transactions. The restriction does not apply if the transaction which causes a
person to become an interested stockholder results in that person owning at
least 85% of the voting stock or if the business combination is approved by the
Board of Directors and authorized by the affirmative vote of at least two-thirds
of the outstanding voting stock not owned by the interested stockholder.
 
INDEMNIFICATION
 
Cintas
 
Washington Business Corporation Act, Section 23A.08.025, allows indemnification
by Cintas to any person made or threatened to be made a party to any
proceedings, other than a proceeding by or in the right of Cintas, by reason of
the fact that he is or was a director, officer, employee or agent of Cintas,
against expenses, including judgments and fines, if he acted in good faith and
in a manner reasonably believed to be in or not opposed to the best interests of
Cintas and, with respect to criminal actions, in which he had no reasonable
cause to believe that his conduct was unlawful. Similar provisions apply to
actions brought by or in the right of Cintas, except that no indemnification
shall be made in proceedings in which the person shall have been adjudged to be
liable to Cintas. Indemnifications are to be made by a majority vote of a quorum
of disinterested directors or the written opinion of independent counsel or by
the stockholders.
 
Article V of the Cintas Bylaws provides that indemnification shall be extended
to any of the persons described above to the full extent permitted by the
Washington Business Corporation Act.
 
Unitog
 
The Unitog Certificate provides that, except as limited by Delaware law, no
director shall be liable to Unitog or its stockholders for monetary damages for
breach of fiduciary duty as a director, except for liability (a) for breaches of
the director's duty of loyalty to the Company or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) pursuant to Section 174 of the Delaware General
Corporation Law, or (d) for any transactions from which the director derived an
improper personal benefit. The effect of these provisions is to eliminate the
right of Unitog and its stockholders (through stockholders derivative suits on
behalf of Unitog) to recover monetary damages against a director for breach of
certain fiduciary duties as director (including breaches resulting from grossly
negligent behavior), except in the situations described above. These provisions
may not limit the liability of directors under federal securities laws.
 
Under Delaware law, directors also have a duty of loyalty to the corporation and
its stockholders. The duty of loyalty requires that, in making a business
decision, directors act in good faith and in the honest belief that the action
taken was in the best interest of the corporation.
 
Pursuant to the Unitog Bylaws and consistent with Delaware law and the Unitog
Certificate, the Unitog Board has the power on behalf of Unitog to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative, including an action by or in the
right of the Corporation, by reason of the fact that he is or was an officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee, agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection
                                      -49-
<PAGE>   57
 
with the defense or settlement of such action, suit or proceeding, including
attorneys fees to the full extent permitted by Delaware law.
 
APPRAISAL OR DISSENTER RIGHTS
 
Cintas
 
Under the Washington Business Corporations Act, a stockholder is entitled to
dissent from and, upon perfection of his or her appraisal rights, to obtain fair
value of his or her shares in the event of certain corporate actions, including
certain mergers, consolidations, share exchanges, sales of substantially all of
the assets of the corporation and amendments to the corporation's articles of
incorporation that materially and adversely affects stockholder rights.
 
Unitog
 
Rights of appraisal provided under Delaware law do not apply to Unitog pursuant
to a statutory exception for corporations whose shares are listed on a national
securities exchange.

    subject to options held by that person that are currently exercisable or
    exercisable within 60 days of February 1, 1999. Such shares issuable

hereto, either as of the date hereof or, subject to the mutual agreement of the
parties, prior to Closing, as exhibits and incorporated herein by reference,
including but not limited to the Exchange Agent Agreement, as well as all

MERGER CONSIDERATION; CONVERSION OR CANCELLATION OF COMPANY SHARES IN THE MERGER
 
5.1 MERGER CONSIDERATION. Subject to the provisions of this Agreement, at the
Effective Time, each Company Share, by virtue of the Merger and without any
action on the part of the holder thereof, other than Company Shares owned by
Parent, Merger Sub, or any direct or indirect wholly owned Subsidiary of Parent,
shall be converted into the right to receive as Merger Consideration, that
number of shares of Parent Common Stock equal to the Conversion Number upon
surrender of the Certificate representing such Company Share, in accordance with
Section 5.3. Exhibit 5.1 illustrates the calculation of the Conversion Number
under varying circumstances.
 
5.2 CANCELLATION OF COMPANY SHARES.
 
(a) All Company Shares to be converted into Parent Common Stock pursuant to
Section 5.1 shall, by virtue of the Merger and without any action on the part of
the holders thereof, cease to be outstanding, be canceled and cease to exist,
and each holder of a Certificate shall thereafter cease to have any rights with
respect to such Company Shares, except the right to receive for each of the
Company Shares, upon the surrender of such Certificate in accordance with
Section 5.3, the Merger Consideration.
 
(b) At the Effective Time, each Company Share issued and outstanding and owned
by Parent, Merger Sub or any direct or indirect wholly owned Subsidiary of
Parent, immediately prior to the Effective Time shall, by virtue of the Merger
and without any action on the part of the holder thereof, cease to be
outstanding, be canceled and cease to exist without payment of any consideration
therefor.
 
(c) At the Effective Time, each share of common stock of Merger Sub issued and
outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of Merger Sub or the holder thereof,
be converted into shares of common stock of the Surviving Company pursuant to
the Certificate of Merger.
 
5.3 PAYMENT FOR COMPANY SHARES IN THE MERGER. The manner of making payment for
Company Shares in the Merger shall be as follows:
 
          (a) At the Effective Time, pursuant to the Exchange Agent Agreement,
     attached hereto as Exhibit 5.3, Parent shall make available to the Exchange
     Agent, the aggregate number of shares of Parent Common Stock constituting
     the Merger Consideration payable pursuant to Section 5.1, which shall
     constitute the Merger Payment Fund. The Exchange Agent shall, pursuant to
     irrevocable instructions, make the payments provided for in this Section
     5.3 out of the Merger Payment Fund. The Merger Payment Fund shall not be
     used for any purpose other than as described herein.
 
          (b) Promptly after the Effective Time, the Exchange Agent shall mail
     to each holder of record of a Certificate or Certificates (i) a form of
     letter of transmittal (which shall specify that delivery shall be effected,
     and risk of loss and title to the Certificates shall pass, only upon proper
     delivery of the Certificates to the Exchange Agent) and (ii) instructions
     for use in effecting the surrender of the Certificates for payment
     therefor. Upon surrender of Certificates to the Exchange Agent, together
     with such letter of transmittal duly executed and any other required
     documents, the holder of such Certificates shall be entitled to receive for
     each of the Company Shares represented by such Certificates the Merger
     Consideration. Until so surrendered, such Certificates shall represent
     solely the right to receive the Merger Consideration with respect to each
     of the Company Shares represented thereby. No interest shall be paid or
     accrue on the Merger Consideration payable upon surrender of the
     Certificates. If any payment of the Merger Consideration is to be made to a
     Person other than the one in whose name the Certificate surrendered in
     exchange therefor is registered, it shall be a condition of such payment
     that the Certificate so surrendered shall be properly endorsed and
     otherwise in proper form for transfer and that the Person requesting such
     payment shall pay to the Exchange Agent any applicable transfer or other
     similar Taxes, or shall establish to the satisfaction of the Exchange Agent
     that any such Tax has been paid or is not applicable. Notwithstanding the
     foregoing, neither the Exchange Agent nor any party hereto shall be liable
     to a holder of Company Shares for any Merger Consideration delivered to a
     public official pursuant to applicable escheat law.

<PAGE>   72
 
          (c) Pursuant to the Exchange Agent Agreement, any portion of the
     Merger Payment Fund (including any dividends thereon or earnings or profits
     with respect thereto on Parent Common Stock) which remains unclaimed by the
     former stockholders of the Company for six months after the Effective Time
     shall be delivered to the Surviving Company, upon demand of the Surviving
     Company, and any former stockholders of the Company shall thereafter look
     only to the Surviving Company for payment of their claim for the Merger
     Consideration for the Company Shares. The Surviving Company's obligations
     to former stockholders of the Company with respect to the payment of Merger
     Consideration shall be guaranteed by Parent.
 
5.4 TRANSFER OF COMPANY SHARES AFTER THE EFFECTIVE TIME. No transfers of Company
Shares shall be made on the stock transfer books of the Company after the close
of business on the business day preceding the date of the Effective Time.
 
5.5 FRACTIONAL SHARES. No fractional shares of Parent Common Stock shall be
issued in the Merger. Each holder of Company Shares shall be entitled to receive
in lieu of any fractional shares of Parent Common Stock to which such holder
otherwise would have been entitled pursuant to Section 5.1 (after taking into
account all Company Shares then held of record by such holder) a cash payment in
an amount equal to the product of (i) the fractional interest of a share of
Parent Common Stock to which such holder otherwise would have been entitled and
(ii) the Parent Share Price. Parent shall timely make available to the Exchange
Agent cash in an amount sufficient to make the payments in lieu of fractional
shares as aforesaid.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
Except as set forth in the Company SEC Reports filed prior to the date of this
Agreement and except as set forth in the Company Disclosure Schedule (each
section of which qualifies the correspondingly numbered representation or
warranty), the Company hereby represents and warrants to Parent and Merger Sub
as follows:
 
6.1 COMPANY SHARES. The Company Shares, at the Effective Time, will constitute
all of the issued and outstanding capital stock of the Company and all such
shares of Company Shares will have been duly authorized, validly issued and
shall be fully paid and non-assessable.
 
6.2 CAPITALIZATION. The entire authorized capital stock of the Company consists
of 30,000,000 shares of common stock, having a per share par value of $.01 per
share, and 150,000 shares of serial preferred stock, having a per share par
value of $.01 per share. As of the date hereof, 9,659,305 shares of such common
stock are issued (including treasury shares) and zero (0) shares of such serial
preferred stock are issued and 255,909 shares of common stock are held in
treasury. As of the date hereof, such shares constitute all of the issued and
outstanding capital stock of the Company, all of which have been duly
authorized, validly issued and are fully paid and non-assessable. All the
outstanding shares of capital stock of each Subsidiary of the Company are owned
by the Company, or by another wholly owned subsidiary of the Company, free and
clear of all Liens, and are duly authorized, validly issued, fully paid and
nonassessable. There are not as of the date hereof, and there will not be at the
Effective Time, any stockholder agreements, voting trusts or other agreements or
understandings to which the Company is a party or to which it is bound relating
to the voting of any shares of the capital stock of the Company, or the capital
stock of any of its Subsidiaries. There are no outstanding or authorized
options, warrants, subscriptions, calls, demands or rights of any character
relating to the Company's capital stock, or the capital stock of its
Subsidiaries, whether or not issued, which the Company, or any of its
Subsidiaries, is a party to, including without limitation, securities
convertible into or evidencing the right to purchase any capital stock or other
securities of the Company or any of its Subsidiaries.
 
6.3 CORPORATE ORGANIZATION, QUALIFICATION AND POWER. Each of the Company and its
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the Laws of the jurisdiction of its incorporation and is duly
qualified to conduct its business and in good standing in every other
jurisdiction in which its business is conducted, except where failure to be so
qualified, licensed or to be in good standing would
 
                                       A-7
<PAGE>   73
 
not, individually or in the aggregate, have a Material Adverse Effect. Each of
the Company and its Subsidiaries has the corporate power to own or lease its
respective properties and to carry on its business as now being conducted,
wherever located. The Company's Subsidiaries are listed on the Company
Disclosure Schedule and the Company owns no other interest in any corporation,
partnership, limited liability company, proprietorship or any other business
entity. The Company has heretofore made available to Parent complete and correct
copies of its Certificate of Incorporation, as amended, and Bylaws, as amended,
and the Articles of Incorporation and Bylaws, or other comparable charter or
organizational documents, of its Subsidiaries, in each case as amended to the
date of this Agreement.
 
6.4 AUTHORIZATION OF AGREEMENT AND MERGER. The Company has the requisite
corporate power and authority to approve, authorize, execute and deliver this
Agreement and to consummate the Transactions (subject to the requisite approval
of the Merger by stockholders of the Company holding a majority of the
outstanding voting stock of the Company, pursuant to Section 251(c) of the
DGCL). This Agreement, and the consummation by the Company of the Transactions
have been duly and validly authorized by the Board of Directors of the Company
and no other corporate proceedings on the part of the Company are necessary to
authorize this Agreement or to consummate the Transactions (other than the
requisite approval of the Merger by the stockholders of the Company and other
than in connection with the actions to be taken pursuant to Section 8.6).
 
6.5 ENFORCEABLE AGREEMENT. This Agreement has been duly and validly executed and
delivered by the Company and, assuming it constitutes the valid and binding
agreement of Parent and Merger Sub, constitutes a valid and binding obligation
of the Company, enforceable against the Company according to its terms, subject
to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
similar Laws affecting the enforceability of contractual obligations and
creditor's rights generally and by the application of equitable principles by
courts of competent jurisdiction, sitting at law or in equity.
 
6.6 NO CONFLICTS, VIOLATIONS, BREACHES OR DEFAULTS. The execution and delivery
of this Agreement by the Company and its performance of the obligations
hereunder, including its execution, delivery and performance of any Additional
Agreements to which it is a party and the consummation of the Transactions, do
not (a) conflict with or result in any breach of any provision of the
Certificate of Incorporation, as amended, or Bylaws, as amended, of the Company
or the comparable charter or organizational documents of any of its
Subsidiaries; (b) require any consent, approval, authorization or permit of, or
filing with, or notification to, any Governmental Authority, except (i) in
connection with the applicable requirements, if any, of the HSR Act; (ii)
pursuant to the applicable requirements of the Securities Act and the Exchange
Act, and the rules and regulations promulgated thereunder; (iii) the filing of
the Certificate of Merger pursuant to the DGCL and appropriate documents with
the relevant authorities of other states in which the Company is authorized to
do business; (iv) such filing or consent as may be required under any
environmental, health or safety Law; (v) such filing or consent as may be
required by applicable state securities, or "blue sky" Laws; (vi) approvals, if
any, required of state Governmental Authorities having jurisdiction over the
Company (identified on the Company Disclosure Schedule); (vii) such filings,
consents, approvals, orders, registrations, declarations and filings as may be
required under the laws of any foreign country in which the Company or any of
its Subsidiaries conducts any business or owns any assets; (viii) filings with,
and approval of, the Exchange; or (ix) where the failure to obtain such consent,
approval, authorization or permit, or to make such filing or notification, would
not, individually or in the aggregate, have a Material Adverse Effect or
materially adversely affect the ability of the Company to consummate the
Transactions; (c) except as would not, individually or in the aggregate, have a
Material Adverse Effect, conflict with or result in a breach or violation of, or
constitute a default under, or result in (or create in any party the right to
cause) the acceleration of any performance required by the Company or its
Subsidiaries under, (i) any Judgment or Law to which they are subject or bound
(subject to any consents, approvals, authorizations, permits, filings or
notifications required under (b) above), or (ii) any mortgage, bond, indenture,
agreement, contract, license or other instrument or obligation to which the
Company and/or its Subsidiaries are subject or bound; or (d) result in the
creation of any Lien on any of the assets of the Company or its Subsidiaries
which, individually or in the aggregate, would have a Material Adverse Effect.
 
6.7 COMPANY SEC REPORTS. Since January 1, 1996, the Company has filed all forms,
reports and documents with the SEC required to be filed by it pursuant to the
federal securities Laws, all of which complied as of their
                                       A-8
<PAGE>   74
 
respective dates in all material respects with all applicable requirements of
the Securities Act and the Exchange Act and the rules and regulations
promulgated thereunder. None of the Company SEC Reports, at the time filed,
contained any untrue statement of a material fact or omitted to state a 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.
 
6.8 FINANCIAL STATEMENTS; ACCOUNTING MATTERS.
 
          (a) The consolidated balance sheets and the related consolidated
     statements of earnings, stockholders' equity and cash flows (including the
     related notes thereto) of the Company included in the Company SEC Reports
     complied as to form in all material respects with the published rules and
     regulations of the SEC with respect thereto, have been prepared in
     accordance with generally accepted accounting principles applied on a basis
     consistent with prior periods (except as otherwise noted therein), and
     present fairly the financial position of the Company and its Subsidiaries
     as of their respective dates, and the consolidated results of its
     operations and its cash flows for the periods presented therein (subject,
     in the case of the unaudited interim financial statements, to normal
     year-end adjustments and except that the unaudited interim financial
     statements do not contain all of the footnote disclosure required by
     generally accepted accounting principles).
 
          (b) Neither the Company nor, to the actual knowledge of the Company's
     officers, any of its affiliates, has taken or agreed to take any action
     that would jeopardize the qualification of the Merger as a reorganization
     within the meaning of Section 368(a) of the Code and the Company has no
     reason to believe that the Merger will not qualify as "pooling of
     interests" for accounting purposes.
 
6.9 PROXY STATEMENT; S-4 REGISTRATION STATEMENT. None of the information
supplied or to be supplied by the Company for inclusion or incorporation by
reference in the Proxy Statement or inclusion in the S-4 Registration Statement
required to be filed in connection with the Transactions (or any amendment or
supplement thereto) will, (a) in the case of the Proxy Statement, at the time of
the mailing of the Proxy Statement and at the times of the Company's Stockholder
Meeting, and (b) in the case of the S-4 Registration Statement, at the time it
becomes effective and at the Effective Time, 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 are made, not misleading. The Company shall
promptly notify Parent if at any time prior to the Effective Time any event
occurs with respect to the Company which is required to be described in an
amendment of, or a supplement to, the S-4 Registration Statement, so that Parent
can promptly file such with the SEC and disseminate it as required by Law. If at
any time prior to the Company's Stockholder Meeting any event occurs with
respect to the Company which is required to be described in an amendment of, or
a supplement to, the Proxy Statement, the Company shall promptly notify Parent,
file such with the SEC and disseminate it to the Company's stockholders as
required by Law. The Proxy Statement will (with respect to the Company and other
information supplied by the Company for inclusion therein) comply as to form in
all material respects with the requirements of the Exchange Act and the rules
and regulations thereunder.
 
6.10 LITIGATION. Except as appropriately reserved for in the financial
statements included within the Company SEC Reports, there is no action, suit,
claim, governmental investigation, arbitration or other proceeding pending, or,
to the actual knowledge of the Company's officers, threatened in writing,
against the Company or any of its Subsidiaries which, if adversely determined,
individually or in the aggregate, would have a Material Adverse Effect.
 
6.11 TAXES. The Company and each of its Subsidiaries has timely filed (or, as to
its Subsidiaries, the Company has timely filed on their behalf) all material Tax
Returns required to be filed by it, has paid (or, as to its Subsidiaries, the
Company has paid on their behalf) all Taxes shown thereon to be due and has
provided (or, as to its Subsidiaries, the Company has made provision on their
behalf) reserves in accordance with generally accepted accounting principles in
its financial statements for any Taxes that have not been paid, whether or not
shown as being due on any Tax Returns, except where the failure to pay or
provide for such Taxes would not, individually or in the aggregate, have a
Material Adverse Effect, and (i) no material claim for unpaid Taxes has been
asserted against the Company or any of its Subsidiaries in writing by a tax
authority or has become a Lien (except for
                                       A-9
<PAGE>   75
 
Liens for Taxes not yet due and payable or for Taxes that are being disputed in
good faith by appropriate proceedings and that have been reserved against in
accordance with generally accepted accounting principles) against the property
of the Company or any of its Subsidiaries, except as to such matters as would
not, individually or in the aggregate, have a Material Adverse Effect, (ii) as
of the date of this Agreement, no audit of any Tax Return of the Company or any
of its Subsidiaries is being conducted by a tax authority, and (iii) as of the
date of this Agreement, no extension of the statute of limitations on the

and is currently in effect. Neither the Company nor any of its Subsidiaries is
or has been a member of any consolidated, combined, unitary or aggregate group
for tax purposes except such a group consisting only of the Company and its
Subsidiaries.
 
6.12 ENVIRONMENTAL LAWS AND REGULATIONS. The Company and each of its
Subsidiaries are in compliance with Environmental Laws (as defined below),
except for non-compliance that would not, individually or in the aggregate, have
or could reasonably be expected to have a Material Adverse Effect. There are no
legal, administrative, arbitral or other proceedings, claims, actions, causes of
action, private environmental investigations or remediation activities or
governmental investigations of any nature that reasonably could be expected to
result in the imposition, on the Company or any of its Subsidiaries, of any
liability or obligation arising under common law standards relating to
environmental protection, human health or safety, or under any local, state,
federal, national or supernational environmental statute, regulation or
ordinance, including the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended (collectively, "Environmental Laws"), pending
or, to the knowledge of the Company, threatened, against the Company or any of
its Subsidiaries, which liability or obligation would have a Material Adverse
Effect. To the knowledge of the Company, during or prior to the period of (i)
its or any of its Subsidiaries' ownership or operation of any of their
respective properties, (ii) its or any of its Subsidiaries' participation in the
management of any property, or (iii) its or any of its Subsidiaries' holding of
a security interest or other interest in any property, there was no release of
hazardous, toxic, radioactive or dangerous materials or other materials
regulated under Environmental Laws in, on, under or affecting any such property
which would reasonably be expected to have a Material Adverse Effect. Neither
the Company nor any of its Subsidiaries is subject to any agreement, order,
judgment or decree by or with any court, Governmental Authority, regulatory
agency or third party imposing any material liability or obligations pursuant to
or under any Environmental Law that would have a Material Adverse Effect.
 
6.13 COMPLIANCE WITH APPLICABLE LAWS. The businesses of the Company and its
Subsidiaries are not being conducted in violation of any Law, except for
possible violations which, individually or in the aggregate, would not have a
Material Adverse Effect.
 
6.14 TITLE TO PROPERTIES. The Company and each of its Subsidiaries has good and
marketable title to, or valid leasehold interests in, all their respective
properties and assets except for such as are no longer used or useful in the
conduct of their respective businesses or as have been disposed of in the
ordinary course of business and except for defects in title, easements,
encroachments, restrictive covenants and similar encumbrances or impediments
that would not, individually or in the aggregate, have a Material Adverse
Effect. All such assets and properties, other than assets and properties in
which the Company or any of its Subsidiaries has leasehold interests, are free
and clear of all Liens except for Liens that would not, individually or in the
aggregate, have a Material Adverse Effect.
 
6.15 INSURANCE. The Company and its Subsidiaries have obtained and currently
maintain in full force and effect insurance with responsible and reputable
insurance companies or associations in such amounts, on such terms and covering
such risks, including fire and other risks insured against by extended coverage,
as is reasonably prudent, and each is maintaining in full force and effect
public liability insurance, insurance against claims for personal injury or
death or property damage occurring in connection with the activities of the
Company or its Subsidiaries or any properties owned, occupied or controlled by
the Company or its Subsidiaries, in such amount as reasonably deemed necessary
by the Company or its Subsidiaries.

6.16 EMPLOYEE BENEFIT MATTERS.
 
          (a) The Company has furnished to Parent true and complete copies of
     all material employee benefit plans within the meaning of Section 3(3) of
     ERISA that covers employees, directors, former employees or former
     directors of the Company and its Subsidiaries, all as listed in the Company
     Disclosure Schedule. In addition, the Company has furnished any trust
     agreements or insurance contracts forming a part of any such employee
     benefit plans maintained by the Company, a copy of the most recent
     determination letter for any such employee benefit plan which is an
     employee pension benefit plan within the meaning of Section 3(2) of ERISA
     and is intended to comply with Section 401(a) of the Code, and a copy of
     the most recent Form 5500, if applicable.
 
          (b) Each of the employee benefit plans maintained by the Company and
     its Subsidiaries is in substantial compliance with all applicable Laws
     including ERISA and the Code, except for any noncompliance that would not
     have a Material Adverse Effect. The Company is not aware of any event (i)
     that would adversely affect any determination letter issued for any such
     employee benefit plan that is an employee pension benefit plan within the
     meaning of Section 3(2) of ERISA and is intended to comply with Section
     401(a) of the Code or (ii) that has occurred to cause the basis for
     imposition of an excise or penalty tax.
 
          (c) All contributions required to be made under the terms of any such
     employee benefit plan have been timely made or have been reflected on the
     latest consolidated balance sheet of the Company in accordance with
     generally accepted accounting principles applied on a consistent basis. No
     condition exists that is reasonably likely to subject the Company or any of
     its Subsidiaries to any direct or indirect liability under Title IV of
     ERISA or to a civil penalty under Section 502 of ERISA or liability under
     Sections 4975, 4976, or 4980B of the Code or the loss of a federal tax
     deduction under Section 280G of the Code or other liability with respect to
     such employee benefit plans that would have a Material Adverse Effect.
 
          (d) No employee benefit plan is a "multiemployer plan" as such term is
     defined in Section 4001(a)(3) of ERISA or Section 414(f) of the Code or a
     multiemployer plan described in clauses (i) or (ii) of Section 3(37)(A) of
     ERISA; is subject to Title IV of ERISA; or is a part of a "multiple
     employer welfare arrangement" within the meaning of Section 3(40) of ERISA.
 
          (e) There are no pending, threatened, or anticipated claims (other
     than routine claims for benefits or immaterial claims) by, on behalf of or
     against any of the employee benefit plans or any trusts related thereto
     that would have a Material Adverse Effect.
 
6.17 BROKER'S FEES. Except for the fees and expenses payable to Goldsmith, Agio,
Helms and Company and George K. Baum & Company, the Company's financial
advisors, which are reflected in their agreements with the Company, true and
correct copies of which have been furnished to Parent, the Company has not
employed any investment bank, broker, finder, consultant or other intermediary,
which would be entitled to any fee or commission from the Company in connection
with the Transactions.
 
6.18 OPINIONS OF FINANCIAL ADVISORS. The Board of Directors of the Company has
received the opinions of Goldsmith, Agio, Helms and Company and George K. Baum &
Company, the Company's financial advisors, to the effect that the Merger
Consideration is fair to the stockholders of the Company other than Parent, from
a financial point of view.
 
6.19 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the Company
SEC Reports, since January 28, 1998, the Company has conducted its business only
in the ordinary course consistent with past practice, and there is not and has
not been: (i) any change which has had a Material Adverse Effect, or (ii) any
condition, event or occurrence which, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect.
 
6.20 INTELLECTUAL PROPERTY. The Company and its Subsidiaries own or have a valid
and enforceable license to use all trademarks, service marks, trade names,
patents and copyrights (in each case, free and clear of any material Liens)
(collectively, "Company Intellectual Property") necessary to carry on its
business substantially as
 
                                      A-11
<PAGE>   77
 
currently conducted, except for such Company Intellectual Property the failure
of which to own or validly license individually or in the aggregate would not
have a Material Adverse Effect and the consummation of the Merger and the other
Transactions will not result in the loss of any such rights (or require the
payment of any material additional fees or royalties in order to maintain such
rights). Neither the Company nor any Subsidiary has received any notices of
infringement of or conflict with, and, to the knowledge of the Company, there
are no infringements of or conflicts with the rights of others with respect to,
any Company Intellectual Property that individually or in the aggregate, in
either such case, would have a Material Adverse Effect.
 
6.21 CONTRACTS. Neither the Company nor any of its Subsidiaries is a party to or
bound by any agreement (i) which would prohibit or materially delay the
consummation of the Merger or any of the Transactions contemplated thereby or
(ii) the performance of which, in accordance with the terms thereof, would have
a Material Adverse Effect.
 
6.22 LABOR MATTERS. As of the date of this Agreement, neither the Company nor
any of its Subsidiaries is a party to or bound by, and none of their employees
is subject to, any collective bargaining agreement relating to the term and
conditions of employment for any group of employees (any such agreement,
memorandum or document, a "Collective Bargaining Agreement"), and as of the date
of this Agreement there are no labor unions or other organizations representing
or, to the knowledge of the Company, purporting to represent, any employees
employed by any of the Company and its Subsidiaries. As of the date of this
Agreement, no labor union is currently engaged in or, to the knowledge of the
Company, threatening, organizational efforts with respect to any employees of
the Company or any of its Subsidiaries.
 
6.23 STATE TAKEOVER STATUTES. The Board of Directors of the Company has approved
this Agreement and the Transactions contemplated hereby and such approval
constitutes approval of the Merger and Transactions by the Company Board of
Directors under the provisions of Section 203 of the DGCL such that Section 203
of the DGCL does not apply to this Agreement and the Transactions. No other
state takeover statute is applicable to the Merger or the Transactions
contemplated hereby.
 
6.24 YEAR 2000 COMPATIBILITY. The Company has developed and is executing a plan
(the "Y2K Plan") to address significant year 2000 compatibility issues. In the
case of certain equipment with imbedded chips where testing for year 2000
compliance is impossible or impractical, the Y2K Plan may include plans and
strategies for replacing such capability with redundant capacity within the
Company or with alternative third party sourcing with comparable quality and
pricing, excluding any provider of basic services and utilities. The Company
represents and warrants that: (i) significant date-sensitive hardware, software,
processes, procedures, interfaces and similar operating systems used within the
Company's operations contain acceptable design and performance specifications so
that such systems will not abruptly end or provide invalid or incorrect results
during the operation of the Company's business on or after January 1, 2000 or
the Company's Y2K Plan makes reasonable provision for addressing any
noncompliant specifications; (ii) all such operating systems have been designed
to ensure year 2000 compatibility including, but not limited to: date data
century recognition, calculations that accommodate same century and
multi-century formulas and date values, date data interface values that reflect
the century, and which include year 2000 leap year calculations or the Company's
Y2K Plan makes reasonable provision for modifying the design and/or replacing
such systems; (iii) the Company is making all reasonable efforts to confirm with
all of its material suppliers that all date-sensitive hardware, software,
processes, procedures, interfaces and similar operating systems used within such
supplier's operations contain acceptable design and performance specifications
so that such systems will not abruptly end or provide invalid or incorrect
results during the operation of the Company's business on or after January 1,
2000 and that all such operating systems have been designed to ensure year 2000
compatibility including, but not limited to: date data century recognition,
calculations that accommodate same century and multi-century formulas and date
values, date data interface values that reflect the century, and which include
year 2000 leap year calculations, so that such material suppliers' operations
will not cause a disruption in the Company's supply, except to the extent that
the failure of such representation or warranty as set forth in this Section 6.24
to be true would not have a Material Adverse Effect.

                                   ARTICLE 7
 
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB
 
Except as set forth in the Parent SEC Reports filed prior to the date of this
Agreement and except as set forth in the Parent Disclosure Schedule (each
section of which qualifies the correspondingly numbered representation or
warranty), Parent and Merger Sub hereby jointly and severally represent and
warrant to the Company as follows:
 
7.1 CAPITALIZATION. The entire authorized capital stock of the Parent consists
of 300,000,000 shares of Parent Common Stock, no par value per share and 100,000
shares of Parent Preferred Stock no par value. As of the date hereof,
105,596,357 shares of Parent Common Stock and no shares of Parent Preferred
Stock are issued and outstanding and no shares of Parent Common Stock or Parent
Preferred Stock are held in treasury. As of the date hereof, such shares
constitute all of the issued and outstanding capital stock of the Parent, all of
which have been duly authorized, validly issued and are fully paid and
non-assessable. All outstanding shares of capital stock of Parent's Subsidiaries
are owned by Parent or a direct or indirect wholly owned subsidiary of Parent,
free and clear of all Liens, and are duly authorized, validly issued, fully paid
and nonassessable. There are not as of the date hereof, and there will not be at
the Effective Time, any stockholder agreements, voting trusts or other
agreements or understandings to which Parent is a party or to which it is bound
relating to the voting of any shares of the capital stock of Parent. As of the
date hereof, 925,050 shares of Parent Common Stock were reserved for issuance
upon exercise of outstanding options under the Parent Option Plans. Except
pursuant to the Parent Option Plans, and as set forth in the Parent Disclosure
Schedule, there are no outstanding or authorized options, warrants, agreements,
subscriptions, calls, demands or rights of any character relating to the
Parent's, or Parent's Subsidiaries' capital stock, whether or not issued,
including without limitation, securities convertible into or evidencing the
right to purchase any capital stock or other securities of Parent or any of its
Subsidiaries. Parent does not own, directly or indirectly, any capital stock of
the Company.
 
7.2 CORPORATE ORGANIZATION, QUALIFICATION AND POWER. Each of Parent, its
Subsidiaries and Merger Sub is a corporation duly organized, validly existing
and in good standing under the Laws of the jurisdiction of its incorporation and
is duly qualified to conduct its business in every other jurisdiction in which
its business is conducted, except where failure to be so qualified or licensed
would not, individually or in the aggregate, have a Material Adverse Effect on
Parent. Each of Parent and its Subsidiaries has the corporate power to own or
lease its respective properties and to carry on its business as now being
conducted, wherever located. Neither Parent nor Merger Sub owns any material
interest in any corporation, partnership, proprietorship or any other business
entity. Each of Parent and Merger Sub has heretofore made available to the
Company complete and correct copies of their respective Articles of
Incorporation, Certificate of Incorporation and Bylaws.
 
7.3 AUTHORIZATION OF AGREEMENT AND MERGER. Each of Parent and Merger Sub has the
requisite corporate power and authority to approve, authorize, execute and
deliver this Agreement and to consummate the Transactions. This Agreement, and
the consummation by Parent and Merger Sub of the Merger and the other
Transactions have been duly and validly authorized by the respective Boards of
Directors of Parent and Merger Sub and the sole stockholder of Merger Sub and no
other corporate proceedings on the part of Parent and Merger Sub are necessary
to authorize this Agreement or to consummate the Transactions (other than in
connection with the actions to be taken pursuant to Section 8.6).
 
7.4 ENFORCEABLE AGREEMENT. This Agreement has been duly and validly executed and
delivered by Parent and Merger Sub and, assuming it constitutes the valid and
binding agreement of the Company, constitutes a valid and binding obligation of
each of Parent and Merger Sub, enforceable against each of them according to its
terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and similar Laws affecting the enforceability of contractual
obligations and creditor's rights generally and by the application of equitable
principles by courts of competent jurisdiction, sitting at law or in equity.
 
7.5 NO CONFLICTS, VIOLATIONS, BREACHES OR DEFAULTS. The execution and delivery
of this Agreement by each of Parent and Merger Sub and its performance of the
obligations hereunder, including its execution, delivery and performance of any
Additional Agreements to which it is a party and the consummation of the
Transactions, do not (a) conflict with or result in any breach of any provision
of the respective Articles of Incorporation, Certificate
 
                                      A-13
<PAGE>   79
 
of Incorporation or Bylaws of Parent or Merger Sub; (b) require any consent,
approval, authorization or permit of, or filing with or notification to, any
Governmental Authority, except (i) in connection with the applicable
requirements, if any, of the HSR Act; (ii) pursuant to the applicable
requirements of the Securities Act and the Exchange Act, and the rules and
regulations promulgated thereunder; (iii) the filing of the Certificate of
Merger pursuant to the DGCL and appropriate documents with the relevant
authorities of other states in which Parent or any of its Subsidiaries is
authorized to do business; (iv) such filing or consent as may be required under
any environmental, health or safety Law; (v) such filing or consent as may be
required by applicable state securities, or "blue sky" Laws; (vi) approvals, if
any, required of state Governmental Authorities having jurisdiction over Parent
or any of its Subsidiaries; (vii) such filings, consents, approvals, orders,
registrations, declarations and filings as may be required under the laws of any
foreign country in which Parent or any of its Subsidiaries conducts any business
or owns any assets; (viii) filings with, and approval of the Exchange; or (ix)
where the failure to obtain such consent, approval, authorization or permit, or
to make such filing or notification, would not, individually or in the
aggregate, have a Material Adverse Effect on Parent or its Subsidiaries or
materially adversely affect the ability of Parent to consummate the
Transactions; (c) except as would not, individually or in the aggregate, have a
Material Adverse Effect on Parent, conflict with or result in a breach or
violation of, or constitute a default under, or result in (or create in any
party the right to cause) the acceleration of any performance of the Parent or
its Subsidiaries under, (i) any Judgment or Law to which they are subject or
bound (subject to any consents, approvals, authorizations, permits, filings or
notifications required under (b) above), or (ii) any mortgage, bond, indenture,
agreement, contract, license or other instrument or obligations to which Parent
and/or its Subsidiaries are subject or bound; or (d) result in the creation of
any Lien on any of the assets of Parent or its Subsidiaries which, individually
or in the aggregate, would have a Material Adverse Effect on Parent or Merger
Sub.
 
7.6 PARENT SEC REPORTS. Since June 1, 1996, Parent has filed all forms, reports
and documents with the SEC required to be filed by it pursuant to the federal
securities Laws, all of which complied in all material respects with all
applicable requirements of the Securities Act and the Exchange Act and the rules
and regulations promulgated thereunder. None of the Parent SEC Reports, at the
time filed, contained any untrue statement of a material fact or omitted to
state a 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.
 
7.7 FINANCIAL STATEMENTS; ACCOUNTING MATTERS.
 
          (a) The consolidated balance sheets and the related consolidated
     statements of income, stockholders' equity and cash flows (including the
     related notes thereto) of Parent included in the Parent SEC Reports
     complied as to form in all material respects with the published rules and
     regulations of the SEC with respect thereto, have been prepared in
     accordance with generally accepted accounting principles applied on a basis
     consistent with prior periods (except as otherwise noted therein), and
     present fairly the financial position of Parent and its Subsidiaries as of
     their respective dates, and the consolidated results of its operations and
     its cash flows for the periods presented therein (subject, in the case of
     the unaudited interim financial statements, to normal year-end adjustments
     and except that the unaudited interim financial statements do not contain
     all of the footnote disclosure required by generally accepted accounting
     principles).
 
          (b) Neither Parent, Merger Sub nor, to the actual knowledge of
     Parent's officers, any of their affiliates, have taken or agreed to take
     any action that would jeopardize the qualification of the Merger as a
     reorganization within the meaning of Section 368(a) of the Code, and Parent
     has no reason to believe that the Merger will not qualify as "pooling of
     interests" for accounting purposes.
 
7.8 PROXY STATEMENT; S-4 REGISTRATION STATEMENT. None of the information
supplied or to be supplied by Parent or Merger Sub for inclusion or
incorporation by reference in the Proxy Statement or inclusion in the S-4
Registration Statement required to be filed in connection with the Transactions
(or any amendment or supplement thereto) will, (a) in the case of the Proxy
Statement, at the time of the mailing of the Proxy Statement and at the time of
the Company's Stockholder Meeting and (b) in the case of the S-4 Registration
Statement, at the time it becomes effective and at the Effective Time, 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
 
                                      A-14
<PAGE>   80
 
circumstances under which they are made, not misleading. If at any time prior to
the Effective Time any event occurs with respect to Parent, its officers and
directors, or any of its Subsidiaries, which is required to be described in an
amendment of, or a supplement to, the S-4 Registration Statement, Parent will
promptly file such with the SEC and disseminate it as required by Law to the
stockholders of Parent. If at any time prior to the Company's Stockholder
Meeting any event occurs with respect to Parent which is required to be
described in an amendment of, or a supplement to, the Proxy Statement, Parent
shall promptly notify the Company, file such with the SEC and disseminate it to
Parent's stockholders as required by Law. The Proxy Statement will (except with
respect to information relating to the Company) comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations thereunder, and the S-4 Registration Statement (except for
information relating to the Company) will comply as to form in all material
respects with the provisions of the Securities Act.
 
7.9 LITIGATION. Except as disclosed in or appropriately reserved for in the
financial statements included within the Parent SEC Reports, there is no action,
suit, claim, governmental investigation, arbitration or other proceeding
pending, or, to the actual knowledge of Parent's officers, threatened in
writing, against Parent which, if adversely determined, individually or in the
aggregate, would have a Material Adverse Effect on Parent.
 
7.10 TAXES. Each of Parent and its Subsidiaries has (a) filed all material Tax
Returns that they are required to file through the date hereof and shall prepare
and file all material Tax Returns required to be filed after the date hereof and
on or before the Effective Time and (b) paid or provided for the payment of all
Taxes due and owing for the periods covered by such Tax Returns and all Taxes,
if any, required to be paid for which no return is required, except in either
case where the failure to file such returns or to pay or provide for such Taxes
would not, individually or in the aggregate, have a Material Adverse Effect on
Parent.
 
7.11 ENVIRONMENTAL LAWS AND REGULATIONS. Parent and each of its Subsidiaries (a)
are in compliance with Environmental Laws, except for non-compliance that would
not, individually or in the aggregate, have a Material Adverse Effect on Parent,
and (b) have not received written notice of, or, to the actual knowledge of
Parent's officers, is the subject of an Environmental Claim which, individually
or in the aggregate, would have a Material Adverse Effect on Parent.
 
7.12 COMPLIANCE WITH APPLICABLE LAWS. The businesses of Parent and its
Subsidiaries are not being conducted in violation of any Law, except for
violations which, individually or in the aggregate, would not have a Material
Adverse Effect on the Parent.
 
7.13 BROKER'S FEES. Parent has not employed any investment bank, broker, finder,
consultant or other intermediary, which would be entitled to any fee or
commission from Parent in connection with the Transactions.
 
7.14 INTERIM OPERATIONS OF MERGER SUB. Merger Sub was formed solely for the
purpose of engaging in the Transactions and has not engaged in any business
activities or conducted any operations other than in connection with the
Transactions. Merger Sub has no Subsidiaries.
 
7.15 AUTHORIZATION FOR PARENT COMMON STOCK. Prior to the Effective Time, Parent
will have taken all necessary action to permit it to issue the number of shares
of Parent Common Stock required to be issued pursuant to Article 5. Parent
Common Stock issued pursuant to Article 5 will, when issued, be validly issued,
fully paid and nonassessable and no Person will have any preemptive right of
subscription or purchase in respect thereof. Such Parent Common Stock will, when
issued, be registered under the Securities Act and the Exchange Act and
registered or exempt from registration under any applicable state securities
laws and will, when issued, be listed on the Exchange, subject to notice of
official issuance.
 
                                   ARTICLE 8
 
                   CONDUCT PENDING THE CLOSING AND COVENANTS
 
8.1 CONDUCT OF BUSINESS BY COMPANY AND PARENT. Each of the Company and Parent
covenants and agrees that prior to the Effective Time, unless the other party
agrees in writing or as otherwise contemplated by this
 
                                      A-15
<PAGE>   81
 
Agreement, it will conduct its business and day to day operations (including
those of any Subsidiary) in the ordinary and usual course of business,
consistent with its past custom and practice, and will seek to preserve intact
its business organization and goodwill, keep in full force and effect all
material rights, licenses, permits and franchises relating to such business, and
maintain satisfactory relationships with suppliers, customers and others having
business relationships with it. Each of the Company and Parent specifically
agrees that, prior to the Effective Time, unless the other party otherwise
agrees in writing or as otherwise contemplated by this Agreement, neither the
Company nor Parent, nor any of the Company's Subsidiaries or Parent's
Subsidiaries, will:
 
          (a) except pursuant to the Option Plans, the Directors Plan or the
     other obligations set forth on the Company Disclosure Schedule or Parent
     Disclosure Schedule or pursuant to the Parent Option Plans, or in
     connection with acquisitions of stock or assets of other businesses by
     Parent or its Subsidiaries, issue, deliver, sell or dispose of, pledge or
     otherwise encumber (i) any additional shares of capital stock of any class,
     or any securities or rights convertible into, exchangeable for or creating
     the right to subscribe for any share of capital stock, or any rights,
     warrants, options, calls, or any other agreement of any kind to purchase or
     acquire any share of capital stock or such securities, or (ii) any
     securities exchangeable for, in respect of, or in substitution for Company
     Stock or Parent Common Stock currently outstanding;
 
          (b) except pursuant to existing employee benefit plans, redeem,

          (c) split, combine, subdivide or reclassify any share of its capital
     stock, or declare, set aside or pay any dividend, or make any distribution,
     on its capital stock, except the declaration and payment of regular
     quarterly, semi-annual or annual cash dividends in accordance with past
     dividend policy (or dividends by a wholly owned Subsidiary);
 
          (d) amend its respective Certificate/Articles of Incorporation or
     Bylaws;
 
          (e) take any action, or fail to take any necessary action that would
     prevent or impede the Merger from qualifying (i) for "pooling of interests"
     accounting treatment or (ii) as a reorganization within the meaning of
     Section 368 of the Code;
 
          (f) except as contemplated by this Agreement, take any action which
     would render, or which reasonably may be expected to render, any
     representation or warranty made by it in this Agreement untrue in any
     material respect at the Effective Time;
 
          (g) except as permitted by Section 8.5, take any action that would, or
     that could reasonably be expected to, cause any condition to Closing, as
     set forth in Article 9 hereof, to not be satisfied; or
 
          (h) authorize, propose or announce an intention to do any of the
     foregoing, or enter into any contract or agreement to do any of the
     foregoing.
 
8.2 CONDUCT OF BUSINESS OF MERGER SUB. During the period of time from the date
of this Agreement to the Effective Time, Merger Sub shall not engage in any
activities of any nature except as provided in or contemplated by this
Agreement.
 
8.3 ENVIRONMENTAL CONSULTANTS, ADJUSTMENT TO COMPANY SHARE PRICE AND MERGER
CONSIDERATION.
 
          (a) Counsel to Parent or Merger Sub has engaged the services of
     Environ Corporation to perform specified environmental investigation and
     testing with respect to the specified plants listed on Exhibit 8.3(a)(1)
     (the "Specified Plants"). The scope of the investigation and testing to be
     conducted will be subject to the terms of Exhibit 8.3(a)(2). All such
     investigation and testing shall be completed as soon as reasonably
     practicable after the date hereof.
 
          (b) Counsel to Parent and the Company will each engage an
     environmental expert (the selection of each expert will be subject to the
     reasonable approval of the other party) (the "Parties' Experts"), and
     counsel to Parent and the Company will jointly engage a third environmental
     expert, to be mutually selected by Parent and the Company (if Parent and
     the Company are unable to agree on the third expert, the Parties' Experts
 
                                      A-16
<PAGE>   82
 
     shall select the third expert) (the "Independent Expert"). Using the test
     results and information developed pursuant to Section 8.3(a), the Parties'
     Experts and the Independent Expert will each prepare an estimate (the
     "Environmental Liability Estimates") of the most likely out of pocket cost
     (including, without limitation, environmental testing, remediation
     expenses, environmental consulting fees, legal fees and government agency
     costs) that will be incurred by the Company in connection with any required
     remediation of the soil and groundwater at the Specified Plants (the
     "Environmental Liability"). Such estimates shall be computed in accordance
     with the specifications and assumptions set forth on Exhibit 8.3(a)(2).
 
          (c) As soon as the Parties' Experts have completed their Environmental
     Liability Estimates, each of the Parties' Experts shall submit its
     Environmental Liability Estimates to the Company and Parent, which
     estimates shall be on a per plant basis and in such detail so as to confirm
     that such estimates were prepared in accordance with the provisions of this
     Agreement. If the difference between such Environmental Liability Estimates
     is in the aggregate less than twenty-five percent (25%) of the higher of
     the two estimates, then the Company Share Price shall be adjusted pursuant
     to Section 8.3(d) using the average of the two Environmental Liability
     Estimates; provided, however, if the higher of the two Environmental
     Liability Estimates is less than or equal to $570,000, then no adjustment
     shall be made to the Company Share Price. If the difference between the
     Environmental Liability Estimates is equal to or greater than twenty-five
     percent (25%) of the higher of the two estimates and if the higher of the
     two estimates is more than $570,000, representatives of the Company and
     Parent shall meet as soon as practicable, but not later than February 17,
     1999, to attempt to reach agreement as to the Estimate Average (as defined
     below), and such amount, if determined, shall be used to calculate the
     reduction in Company Share Price, if any, pursuant to Section 8.3(d). If
     the Company and Parent are unable to reach agreement by February 19, 1999,
     (i) the Independent Environmental Expert shall, as soon as practical,
     deliver its Environmental Liability Estimate to the Company and Parent, and
     (ii) the average of the two Estimates closest in amount (among those
     prepared by the three (3) environmental experts) shall equal the Estimate
     Average for purposes of determining the reduction in Company Share Price,
     pursuant to Section 8.3(d). In all instances, the Estimate Average and the
     calculation of the reduction, if any, in the Company Share Price shall be
     determined no later than February 23, 1999.
 
          (d) (i) If the average of the Environmental Liability Estimates
     calculated pursuant to Section 8.3(c) (the "Estimate Average") is less than
     or equal to the $570,000, then no adjustment shall be made to the Company
     Share Price;
 
             (ii) If the Estimate Average exceeds $570,000, the Company Share
     Price shall be reduced by $.01 for each $100,000 (rounded to the nearest
     $100,000) by which the Estimate Average exceeds $570,000.
 
          (e) Notwithstanding the foregoing, no adjustment shall be made to the
     Company Share Price to the extent the Company, prior to the determination
     of the Estimate Average, has obtained a new insurance policy or policies
     and/or has entered into a new contractual arrangement whereby the Company
     shall be indemnified for or relieved of responsibility for payment of the
     particular Environmental Liability, which insurance and/or contract are
     acceptable to Parent in its reasonable discretion. Any premiums required to
     be paid in connection with such insurance shall be included in the Estimate
     Average.
 
          (f) Parent or Merger Sub shall pay for all costs under Section
     8.3(a)-(c), except (i) the Company will pay for the fees and expenses of
     the environmental expert it selected pursuant to Section 8.3(b), and (ii)
     the Company shall pay one-half of the fees and expenses of the Independent
     Expert.
 
          (g) All costs incurred pursuant to this Section 8.3 shall be included
     in the Estimate Average.
 
8.4 ADDITIONAL COVENANTS OF THE COMPANY. The Company agrees, in addition to the
covenants set forth in Section 8.1, that prior to the Effective Time, without
the express written consent of Parent, neither the Company nor any of the
Company's Subsidiaries will:
 
          (a) adopt a plan of liquidation dissolution, merger (other than the
     Merger), consolidation, restructuring, or other reorganization of the
     Company or any Subsidiary, except as set forth on the Company Disclosure
     Schedule;
 
                                      A-17
<PAGE>   83
 
          (b) terminate, establish, adopt, enter into, or make any new grants or
     awards of stock based compensation or other benefits under, amend or
     otherwise modify the Option Plans, the Directors Plan or any Company
     benefit plan or arrangement or, increase the salary, wage, bonus or other
     compensation of directors, officers or key employees (except the Company
     may increase compensation for key employees in customary amounts, but not
     in excess of 5%);
 
          (c) except in the ordinary course of business, consistent with past
     practice, incur any debt for borrowed money or guarantee any such debt or
     encumber any asset in connection with any such debt, or make any loans,
     advances or capital contributions to, or investments in any other Person,
     other than a wholly owned Subsidiary;
 
          (d) make any acquisition, through merger, consolidation or otherwise,
     except as set forth on the Company Disclosure Schedule;
 
          (e) make any capital expenditure or commitment in excess of $100,000;
     or
 
          (f) purchase any shares of Company Stock pursuant to any existing or
     hereinafter enacted stock repurchase plan or otherwise purchase any shares
     of Company Stock.
 
8.5 ACQUISITION PROPOSALS. The Company shall not, nor shall it permit any of its
Subsidiaries to, nor shall it authorize or permit any of its directors, officers
or employees or any investment banker, financial advisor, attorney, accountant
or other representative retained by it or any of its Subsidiaries to, directly
or indirectly through another person, (i) solicit, initiate or encourage, or
take any other actions designed to facilitate, any inquiries or the making of
any proposal which constitutes an Acquisition Proposal or (ii) participate in
any discussions or negotiations regarding any Acquisition Proposal. Further, the
Company and its officers and directors will cease any existing discussions or
negotiations, if any, with any parties conducted heretofore with respect to any
Acquisition Proposal. Notwithstanding the foregoing, if the Board of Directors
of the Company reasonably determines that it has received a Superior Proposal,
the Company may furnish information and access to the Person who has submitted
such Superior Proposal pursuant to confidentiality agreements, and may
participate in discussions and negotiate with such Person concerning any
proposed merger, sale of assets, sale of shares of capital stock or similar
transaction involving the Company. Notwithstanding the foregoing, nothing herein
shall require the Company's Board of Directors on behalf of the Company (a) to
act, or refrain from acting, in any manner which, in the opinion of such Board
of Directors after consultation with its legal counsel, would be inconsistent
with its fiduciary duties to the Company's stockholders under applicable Law,
(b) to fail to comply with Rule 14d-9 or Rule 14e-2 promulgated under the
Exchange Act with regard to an Acquisition Proposal, or (c) to fail to make any
public statement required by Law or the requirements of the Exchange. If the
Company receives a Superior Proposal, the Company shall immediately advise
Parent in writing of the terms of the Superior Proposal and the identity of the
Person making the Superior Proposal.
 
8.6 STOCKHOLDERS' APPROVAL.
 
          (a) The Company shall promptly submit this Agreement and the
     Transactions for the approval of its stockholders at the Company's
     Stockholder Meeting. The Company shall use all reasonable efforts to obtain
     stockholder approval and adoption of this Agreement and the Transactions
     (including the recommendation by the Company, through its Board of
     Directors, to its stockholders of the approval of the Transactions)
     subject, in each case, to the determination of the Board of Directors of
     the Company after consultation with its counsel that the foregoing actions
     would not be inconsistent with its fiduciary duties to the Company's
     stockholders under applicable Law. The Company will use all reasonable
     efforts to hold the Company's Stockholder Meeting as soon as practicable
     following the date upon which the S-4 Registration Statement becomes
     effective. Without limiting the generality of the foregoing, but subject to
     its right to terminate this Agreement as set forth herein, the Company
     agrees that its obligations pursuant to the first sentence of this Section
     8.6(a) shall not be affected by an Acquisition Proposal, including any
     Superior Proposal.
 
          (b) Notwithstanding the foregoing, the Board of Directors of the
     Company may at any time prior to the Effective Time withdraw, modify or
     change any recommendation and declaration regarding this Agreement, the
     Merger, or the other Transactions, or recommend and declare advisable a
     Superior Proposal, if in the
 
                                      A-18
<PAGE>   84
 
     opinion of such Board of Directors, after consultation with its counsel,
     the failure to so withdraw, modify or change its recommendation and
     declaration would reasonably likely be inconsistent with its fiduciary
     duties to the Company's stockholders under applicable Law.
 
8.7 ALL REASONABLE EFFORTS.
 
          (a) Subject to the terms and conditions herein, each of the parties
     hereto shall use all reasonable efforts to take, or cause to be taken, all
     action and to do, or cause to be done, all things necessary, proper or
     advisable under applicable Laws to consummate and make effective the
     Transactions, including using all reasonable efforts to obtain all
     necessary or appropriate waivers, consents and approvals, to effect all
     necessary registrations, filings and submissions, including, but not
     limited to, (i) filings under the HSR Act and any other submissions
     requested by any Governmental Authority and (ii) required approvals under
     the applicable state Laws and to lift any injunction or other legal bar to
     the Merger (and, in such case, to proceed with the Merger as expeditiously
     as possible), subject, however, to the requisite votes of the stockholders
     of the Company, and Merger Sub.
 
          (b) Notwithstanding the foregoing, the Company shall not be obligated
     to use all reasonable efforts to take any action pursuant to this Section
     8.7 if in the opinion of its Board of Directors after consultation with its
     counsel such actions would be reasonably likely to be inconsistent with its
     fiduciary duties to the Company's stockholders under applicable Law.
 
8.8 ACCESS TO/CONFIDENTIALITY OF INFORMATION. Upon reasonable notice, each of
the Company and Parent shall (and shall cause its Subsidiaries to) afford to
each other's Representatives, so that they may evaluate the Transactions,
reasonable access during normal business hours throughout the period prior to
the Effective Time, to its properties, personnel, books and records and other
information as reasonably requested under the circumstances, and, during such
period, furnish promptly to such Representatives the specific information
concerning its business, properties and personnel as listed on the Parent
Disclosure Schedule. Each of the Company and Parent agrees that it will not, and
will cause its Representatives not to, use any information obtained pursuant to
this Section 8.8 for any purpose unrelated to the consummation of the
Transactions.
 
8.9 PUBLICITY. The parties will consult with each other and will mutually agree
upon any press releases or public announcement pertaining to the Merger and the
other Transactions and shall not issue any such press releases or make any such
public announcements prior to such consultation and agreement, except as may be
required by applicable Law or by obligations pursuant to any listing agreement
with the Exchange, in which case the party proposing to issue such press release
or make such public announcement shall use all reasonable efforts to consult in
good faith with the other party before any such issuance or announcement.
 
8.10 INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
          (a) From and after the Effective Time, Parent shall, and shall cause
     the Surviving Company to, indemnify and hold harmless each present and
     former director and officer of the Company and/or its Subsidiaries (when
     acting in such capacity) determined as of the Effective Time, against any
     costs or expenses (including reasonable attorneys' fees), judgments, fines,
     losses, claims, damages or liabilities, incurred in connection with any
     claim, action, suit, proceeding or investigation, whether civil, criminal,
     administrative or investigative, arising out of or pertaining to matters
     existing or occurring at or prior to the Effective Time, whether asserted
     or claimed prior to, at or after the Effective Time, to the fullest extent
     permitted under the DGCL (and the Surviving Company shall also advance
     expenses as incurred to the fullest extent permitted under applicable law,
     provided the Person to whom expenses are advanced provides an undertaking
     to repay such advances if it is ultimately determined that such Person is
     not entitled to indemnification). Notwithstanding the above, such
     indemnification shall not be applicable to any claims made against any
     Indemnified Party if a judgment or other final adjudication established
     that his or her acts or omissions (A) were committed in bad faith or were
     the result of active and deliberate dishonesty and were material to the
     cause of action so deliberated or (B) arose out of, were based upon or were
     attributable to the gaining in fact of any financial profit or other
     advantage to which he or she was not legally entitled.

<PAGE>   85
 
          (b) Any Person wishing to claim indemnification under Section 8.10(a),
     upon learning of any such claim, action, suit, proceeding or investigation,
     shall promptly notify the Surviving Company thereof, but the failure to so
     notify shall not relieve the Surviving Company of any liability it may have
     to such Person if such failure does not materially prejudice the Surviving
     Company. In the event of any such claim, action, suit, proceeding or
     investigation (whether arising before or after the Effective Time), (i) the
     Surviving Company shall have the right to assume the defense thereof and
     the Surviving Company shall not be liable to any Person seeking
     indemnification under Section 8.10(a) for any legal expenses of other
     counsel or any other expenses subsequently incurred by such Person in
     connection with the defense thereof, except that if the Surviving Company
     elects not to assume such defense or counsel for such Person advises that
     there are issues which raise conflicts of interest between the Surviving
     Company and such Person, such Person may retain counsel satisfactory to
     them, and the Surviving Company shall pay all reasonable expenses of such
     counsel for such Person promptly as statements therefor are received, (ii)
     such Persons will cooperate in the defense of any such matter, and (iii)
     the Surviving Company shall not be liable for any settlement effected
     without its prior written consent.
 
          (c) The Surviving Company shall maintain a policy of officers' and
     directors' liability insurance for acts and omissions occurring prior to
     the Effective Time 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 five years after the Effective Time.
 
          (d) If Parent, the Surviving Company or any of their 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 Company shall assume
     all of the obligations set forth in this Section 8.10.
 
          (e) The provisions of this Section 8.10 are intended for the benefit
     of, and shall be enforceable by, the Persons with rights of
     indemnification, their heirs and their representatives.
 
8.11 EMPLOYEES.
 
          (a) Except as set forth on the Parent Disclosure Schedule, for a
     period of two years following the Effective Time, Parent agrees to provide
     employee benefit plans, programs, arrangements and policies for the benefit
     of employees of the Company and its Subsidiaries not subject to collective
     bargaining that in the aggregate as determined by Parent acting reasonably,
     are no less favorable than those of the Company plans, programs,
     arrangements or policies prior to the Effective Time. All service credited
     to each employee by the Company or its Subsidiaries through the Effective
     Time shall be recognized by Parent for all purposes, including for purposes
     of eligibility, vesting and benefit accruals under any employee benefit
     plan provided by Parent for the benefit of the employees except that
     employees will not be credited with their years of service with the Company
     for purposes of determining benefits accruals pursuant to the Parent's
     Partners Plan.
 
          (b) Parent and the Surviving Company hereby agree to honor (without
     modification) and assume the retention program, enhanced severance plan and
     noncompetition and severance agreements listed on the Company Disclosure
     Schedule, all as in effect at the Effective Time. The Company agrees not to
     amend or modify such programs, plans and agreements prior to the Effective
     Time without Parent's written consent. Anything in this Agreement to the
     contrary notwithstanding, the Company may establish an escrow arrangement
     and fund such escrow as contemplated under the Severance and Noncompetition
     Agreements listed in the Company Disclosure Schedule and Parent and the
     Company hereby agree to honor and assume such escrow arrangement without
     modification.
 
          (c) Notwithstanding any other provision set forth in Section 8.11,
     with respect to employees who are subject to a collective bargaining
     agreement, all benefits shall be provided only in accordance with the
     applicable collective bargaining agreement.
 
                                      A-20

8.12 REGISTRATION STATEMENT. Parent and the Company will, as promptly as
practicable, prepare and file with the SEC the Proxy Statement, with form of
proxy in connection with the vote of Company stockholders with respect to the
Merger, this Agreement and the issuance of the Parent Common Stock pursuant to
the Merger, respectively. Parent will, as promptly as practicable, prepare and
file with the SEC the S-4 Registration Statement, containing the Proxy
Statement, in connection with the registration under the Securities Act of
Parent Common Stock issuable upon conversion of the Company Shares. Parent and
the Company will each use all reasonable efforts to have or cause the S-4
Registration Statement declared effective as promptly as practicable, including,
without limitation, causing their accountants to deliver necessary or required
instruments such as opinions and certificates, and will take any other action
required or necessary to be taken under federal or state securities Laws or
otherwise in connection with the registration process. The Company will use all
reasonable efforts to cause the Proxy Statement to be mailed to its stockholders
at the earliest practicable date. The Company and Parent will cooperate with
respect to the Company's Stockholders Meeting and the Company shall use all
reasonable efforts to hold such meeting as soon as practicable after the date
hereof.
 
8.13 EXCHANGE LISTING. Parent shall cause the Parent Common Stock constituting
the Merger Consideration to be listed on the Exchange, subject to notice of
official issuance thereof.
 
8.14 AFFILIATES.
 
          (a) Company shall deliver to Parent a letter identifying all Persons
     whom the Company believes to be, at the date of the Company's Stockholders
     Meeting, "affiliates" of such party for purposes of applicable
     interpretations regarding use of the pooling-of-interests accounting method
     and for purposes of Rule 145 under the Securities Act. The Company shall
     use all reasonable best efforts to cause each Person who is identified as
     an "affiliate" in the letter referred to above to deliver to Parent on or
     prior to the date of the Company's Stockholders Meeting a written
     agreement, in the form attached hereto as Exhibit 8.14.
 
          (b) The shares of Parent Common Stock issued to 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 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. Any Company Shares held by any such
     affiliate shall not be transferable, regardless of whether such affiliate
     has provided the applicable written agreement referred to in this Section,
     if such transfer, either alone or in the aggregate with other transfers by
     affiliates, would preclude Parent's ability to account for the business
     combination to be effected by the Merger as a pooling of interests. Parent
     shall not register the transfer of any Certificate unless such transfer is
     made in compliance with the foregoing.
 
8.15 LETTERS OF ACCOUNTANTS. Each of the Company and Parent shall use their
reasonable efforts to cause to be delivered to the other the "comfort" letters
of KPMG Peat Marwick LLP and Ernst & Young LLP, independent accountants to each
such party, respectively, dated a date within two business days before the date
on which the S-4 Registration Statement shall become effective and addressed to
the other, in form and substance reasonably satisfactory to the other and
customary in scope and substance for "comfort" letters delivered by independent
public accountants in connection with registration statements and proxy
statements similar to the S-4 Registration Statement and Proxy Statement.
 
8.16 REORGANIZATION. Neither the Company nor Parent and its Subsidiaries will
take any action that would jeopardize the qualification of the Merger as a
reorganization within the meaning of Section 368(a) of the Code.
 
8.17 STOCK OPTIONS.
 
          (a) All Options outstanding at the Effective Time, shall remain
     outstanding following the Effective Time and will continue in accordance
     with their current terms (except to the extent such terms and conditions
     are altered in accordance with their terms as a result of the consummation
     of the Transactions including the terms which apply in the event of a
     "change of control" of the Company). A listing of
 
                                      A-21
<PAGE>   87
 
     outstanding Options as of the date hereof, showing what portions of such
     Options are exercisable as of such date, the dates upon which such Options
     expire, the exercise prices of such Options, and whether such Options are
     intended to qualify as "incentive stock options" within the meaning of
     Section 422 of the Code, is set forth on the Company Disclosure Schedule.
     At the Effective Time, the Options shall, by virtue of the Merger and
     without any further action on the part of the Company or the holder
     thereof, be assumed by Parent in such manner that Parent (i) is a
     corporation "assuming a stock option in a transaction to which Section
     424(a) applies" within the meaning of Section 424 of the Code or (ii) to
     the extent that Section 424 of the Code does not apply to any such Options,
     would be such a corporation were Section 424 of the Code applicable to such
     Options. From and after the Effective Time, all references to the Company
     in the Option Plans and the applicable stock option agreements issued
     thereunder shall be deemed to refer to Parent which shall have assumed the
     Option Plans as of the Effective Time by virtue of this Agreement and
     without any further action. Each Substitute Option assumed by Parent shall
     be exercisable upon the same terms and conditions as under the applicable
     Option Plan and/or the applicable agreement, except that (A) each such
     Substitute Option shall be exercisable for, and represent the right to
     acquire, that whole number of shares of Parent Common Stock (rounded up or
     down to the nearest whole share) equal to the number of shares of Company
     Common Stock subject to such Option multiplied by the Conversion Number;
     and (B) the option price per share of Parent Common Stock shall be an
     amount equal to the option price per share of Company Common Stock subject
     to such Company Stock Option in effect immediately prior to the Effective
     Time divided by the Conversion Number (the option price per share, as so
     determined, being rounded upward to the nearest full cent). Such Substitute
     Option shall otherwise be subject to the same terms and conditions as such
     Option, which is in accordance with the terms thereof.
 
          (b) As soon as practicable after the Effective Time, Parent shall
     deliver to each holder of an Option an appropriate notice setting forth
     such holder's rights pursuant thereto and such Option shall continue in
     effect on the same terms and conditions (including any antidilution
     provisions, and subject to the adjustments required by this Section 8.17
     after giving effect to the Merger). Parent shall comply with the terms of
     all such Options and ensure, to the extent required by, and subject to the
     provisions of, the Option Plans, that Options which qualified as incentive
     stock options under Section 422 of the Code prior to the Effective Time
     continue to qualify as incentive stock options after the Effective Time.
     Parent shall take all corporate action necessary to reserve for issuance,
     prior to the Effective Time, a sufficient number of shares of Parent Common
     Stock for delivery upon exercise of Substitute Options pursuant to the
     terms set forth in this Section 8.17. As soon as practicable after the
     Effective Time, the shares of Parent Common Stock subject to Options will
     be covered by an effective registration statement on Form S-8 (or any
     successor form) or another appropriate form and Parent shall use its best
     efforts to maintain the effectiveness of such registration statement or
     registration statements for so long as Substitute Options remain
     outstanding. In addition, Parent shall use all reasonable efforts to cause
     the shares of Parent Common Stock subject to Options to be listed on the
     Exchange.
 
8.18 POOLING OF INTERESTS. The Company shall cooperate with Parent in its
efforts to cause the transactions contemplated by the Agreement, including the
Merger, to be accounted for as a pooling of interests under Opinion 16 of the
Accounting Principles Board and applicable SEC rules and regulations, and such
accounting treatment to be accepted by the SEC. Neither Parent nor Company shall
take any action that would cause such accounting treatment not to be obtained.
 
8.19 STANDSTILL AGREEMENTS; CONFIDENTIALITY AGREEMENTS. During the period from
the date of this Agreement through the Effective Time, the Company shall not
terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which it or any of its respective Subsidiaries is a
party. During such period, the Company shall enforce, to the fullest extent
permitted under applicable law, the provisions of any such agreement, including
by obtaining injunctions to prevent any breaches of such agreements and to
enforce specifically the terms and provisions thereof in any court of the United
States of America or of any state having jurisdiction.
 
8.20 COMPANY STOCK REPURCHASE PLAN. The Company agrees, prior to the Effective
Time, to rescind and terminate its stock repurchase plan.

each of the following conditions:
 
           (a) Injunction. There shall not be in effect any Law or any Judgment

     prior to invoking this condition each party shall use all reasonable
     efforts to have any such Judgment vacated; and there shall have been no Law
     enacted or promulgated which would make consummation of the Transactions
     illegal or which would have or reasonably be expected to have a Material
     Adverse Effect.
 
          (b) Stockholder Approval. This Agreement and the Merger shall have
     been duly approved by the stockholders of the Company in accordance with
     applicable Law and the Certificate of Incorporation, as amended, of the
     Company at the Company's Stockholder Meeting. Parent represents that the
     issuance of Parent Common Stock in connection with the Merger does not
     require shareholder approval under applicable law.
 
          (c) HSR Act. Any waiting period (and any extension thereof) applicable
     to the consummation of the Merger under the HSR Act shall have expired or
     shall have been earlier terminated.

     Registration Statement shall have become effective and no stop order
     suspending its effectiveness shall have been issued and no proceedings for

     shall have received all state securities Law or "blue sky" permits and
     authorizations necessary to issue Parent Common Stock in exchange for the
     Company Shares in the Merger.
 
          (e) Listing of Parent Common Stock. The shares of Parent Common Stock
     constituting the aggregate stock portion of the Merger Consideration and
     the other such shares required to be reserved for issuance in connection
     with the Merger shall have been authorized for listing on the Exchange,
     subject to notice of official issuance.
 
          (f) Pooling. Parent and the Company shall each have received an
     opinion of their respective independent accounting firms to the effect that
     the Merger will be accounted for as a pooling of interests under Opinion 16
     of the Accounting Principles Board and applicable SEC rules and
     regulations.
 
          (g) Financial Advisors' Opinions. The Company shall have received
     letters from its financial advisors, dated the Closing Date, to the effect
     that the letters previously delivered by such advisors which provide that

     than the Parent are in full force and effect.
 
9.2 ADDITIONAL CONDITIONS TO THE OBLIGATIONS OF PARENT AND MERGER SUB TO

are subject to satisfaction, or, to the extent permitted by Law, waiver on or
prior to the Effective Time of each of the following conditions:

     of the Company shall be true and correct, in each such case as of the date
     of this Agreement and as of the Effective Time as though made on the
     Effective Time (except that representations and warranties that speak as of
     a specific date shall be true and correct as of such date), provided that
     for purposes of determining the satisfaction of the foregoing, such
     representations and warranties shall be deemed true and correct if the
     failure or failures of such representations and warranties to be so true
     and correct (excluding the effect of any qualification set forth
 
                                      A-23
<PAGE>   89
 
     therein relating to "materiality" or a "Material Adverse Effect") have not
     had and could not reasonably be expected to have, individually or in the
     aggregate, a Material Adverse Effect.
 
          (c) Deliveries. Parent shall have received at the Effective Time:
 
             (i) a certificate dated the Effective Time and executed by the

     legally required to be obtained to consummate the Merger shall have been
     obtained from all Governmental Entities, except for such consents,
     approvals and authorizations the failure of which to obtain would not have
     a Material Adverse Effect on Parent (assuming for purposes of this Section
     9.2(d) that the Merger shall have been effected).
 
          (e) Tax Opinion. Parent shall have received an opinion, based on
     appropriate representations contained in certificates of the Company,

     conversion of the Company Shares into Parent Common Stock pursuant to the
     terms of the Merger (except with respect to cash received in lieu of
     fractional share interests in Parent). Such counsel may rely on
     representations made herein and customary certifications from officers of
     Company and Parent in issuing such opinion.
 
          (f) Legal Opinion. Parent shall have received from counsel to the
     Company an opinion in form and substance substantially as set forth in
     Exhibit 9.2 attached hereto addressed to Parent and Merger Sub, and dated
     as of the date of Closing.
 
9.3 ADDITIONAL CONDITIONS TO THE COMPANY'S OBLIGATION TO CLOSE. The obligation
of the Company to consummate the Transactions is subject to satisfaction, or, to
the extent permitted by Law, waiver on or prior to the Effective Time of each of
the following conditions:
 
          (a) Performance. Parent and Merger Sub shall have performed in all
     material respects, all the obligations required to be performed by them
     under this Agreement at or prior to the Effective Time.
 
          (b) Representations and Warranties. The representations and warranties
     of Parent and Merger Sub shall be true and correct, in each such case as of
     the date of this Agreement and as of the Effective Time as though made on
     the Effective Time (except that representations and warranties that speak
     as of a specific date shall be true and correct as of such date), provided
     that for purposes of determining the satisfaction of the foregoing, such
     representations and warranties shall be deemed true and correct if the
     failure or failures of such representations and warranties to be so true
     and correct (excluding the effect of any qualification set forth therein
     relating to "materiality" or a "Material Adverse Effect") have not had and
     could not reasonably be expected to have, individually or in the aggregate,
     a Material Adverse Effect.
 
          (c) Deliveries. The Company shall have received at the Effective Time:
 
             (i) a certificate dated the Effective Time and executed by the
        Chief Executive Officer or President of Parent certifying to the
        fulfillment of the conditions specified in Sections 9.3(a) and (b), and
        as to Parent and Merger Sub, fulfillment of the conditions specified in
        Sections 9.1(b), (d) and (e);
 
                                      A-24
<PAGE>   90
 
             (ii) certified or verified copies of Parent and Merger Sub's
        respective Articles of Incorporation and Certificate of Incorporation,
        as currently amended, and certificates of good standing for Parent and
        Merger Sub, as the Company may reasonably request; and
 
             (iii) a copy of the Exchange Agent Agreement pursuant to Section
        5.3.
 
          (d) Consents and Approvals. All consents, approvals and authorizations
     legally required to be obtained to consummate the Merger shall have been
     obtained from all Governmental Entities, except for such consents,
     approvals and authorizations the failure of which to obtain would not have
     a Material Adverse Effect (assuming for purposes of this Section 9.3(d)
     that the Merger shall have been effected).
 
          (e) Tax Opinion. The Company shall have received an opinion, based on
     appropriate representations contained in certificates of the Company,
     Parent, Merger Sub, their respective officers and others, of Bryan Cave
     LLP, dated the Effective Time, to the effect that (i) the Merger will be
     treated for federal income tax purposes as a reorganization within the
     meaning of Section 368(a) of the Code; (ii) each of Parent, Merger Sub and
     the Company will be a party to the reorganization within the meaning of
     Section 368(b) of the Code; and (iii) no gain or loss will be recognized by
     a stockholder of the Company as a result of the conversion of the Company
     Shares into Parent Common Stock pursuant to the terms of the Merger (except
     with respect to cash received in lieu of fractional share interests in
     Parent). Such counsel may rely on representations made herein and customary
     certifications from officers of Company and Parent in issuing such opinion.
 
          (f) Legal Opinion. The Company shall have received from counsel to
     Parent and Merger Sub an opinion in form and substance substantially as set
     forth in Exhibit 9.3 attached hereto, addressed to the Company and dated as
     of the date of Closing.
 
9.4 FRUSTRATION OF CLOSING CONDITIONS. Neither Parent nor the Company may rely
on the failure of any condition set forth in Section 9.1, 9.2 or 9.3, as the
case may be, to be satisfied if such failure was caused by such party's failure
to use reasonable best efforts to consummate the Merger and the other
transactions contemplated by this Agreement.

10.1 TERMINATION. This Agreement may be terminated and the Merger may be
abandoned at any time prior to the Effective Time, before or after the approval
by stockholders of either or both of the Company and Parent,
 
(a) by the mutual written consent of Parent and the Company;
 
(b) by either Parent or the Company, if:
 
          (i) any court of competent jurisdiction in the United States, or some
     other Governmental Authority, shall have issued an order, decree or ruling
     or taken any other action permanently restraining, enjoining or otherwise
     prohibiting the Merger and such order, decree, ruling or other action shall
     have become final and nonappealable; provided, however, that the party
     seeking to terminate this Agreement under this Section 10.1(b)(i) shall
     have used its best efforts to remove such injunction, order or decree; or
 
          (ii) the Merger shall not have been consummated by June 30, 1999;
     provided, that the right to terminate this Agreement pursuant to this
     Section 10.1(b)(ii) shall not be available to any party whose failure to
     fulfill any of its obligations under this Agreement results in the failure
     of the Merger to occur on or before such date; provided further Parent
     shall not have the right to terminate this Agreement under this Section
     10.1(b)(ii) until July 31, 1999, if the Merger shall not have been
     consummated as a result of (A) all required regulatory approvals or
     consents necessary to satisfy the conditions set forth in Section 9.2(d)
     shall not have been received by July 31, 1999; (B) the entering of an order
     or any pending action commenced by any applicable federal governmental
     antitrust authority seeking an order which would have the effect of making
     the Merger illegal or otherwise materially and adversely affecting the
     value of the Company or
 
                                      A-25
<PAGE>   91
 
     prohibiting consummation of the Merger, or (C) the failure of the
     conditions set forth in Section 9.1(c) to be satisfied;
 
          (iii) to the extent required by applicable Law, this Agreement and the
     Merger shall have been voted on by stockholders of the Company at the
     Company's Stockholder Meeting and the vote shall not have been sufficient
     to satisfy the condition set forth in Section 9.1(b); or
 
          (iv) if the aggregate adjustment to the Company Share Price pursuant
     to Section 8.3(d)(ii) is more than $2.00.
 
(c) by Parent, if:
 
          (i) there has been a misrepresentation or breach of warranty or a
     failure to perform a covenant on the part of the Company with respect to
     its representations, warranties and covenants set forth in this Agreement
     (excluding the effect of any qualification set forth therein relating to
     "materiality" or a "Material Adverse Effect") of which the Company has been
     given notice in writing by Parent and which has not been cured by the
     Company within thirty (30) days of such notice and which misrepresentation,
     breach or failure to perform would, in the aggregate with all other
     misrepresentations, breaches or failures to perform, have a Material
     Adverse Effect; or
 
          (ii) the Board of Directors of the Company withdraws or materially
     modifies or changes its recommendation of this Agreement or the Merger in a
     manner adverse to Parent or Merger Sub.
 
(d) by the Company, if:
 
          (i) there has been a misrepresentation or breach of warranty or
     failure to perform a covenant on the part of the Parent or Merger Sub with
     respect to its or their representations, warranties and covenants set forth
     in this Agreement (excluding the effect of any qualification set forth
     therein relating to "materiality" or a "Material Adverse Effect") of which
     the Parent and/or Merger Sub, as the case may be, has been given notice in
     writing by the Company and which has not been cured by Parent or Merger
     Sub, as the case may be, within thirty (30) days of such notice and which
     misrepresentation, breach or failure to perform would have a Material
     Adverse Effect;
 
          (ii) in the exercise of good faith judgment as to its fiduciary duties
     to the Company's stockholders as imposed by applicable Law and, after
     consultation with legal counsel, the Company's Board of Directors
     determines that such termination is required by reason of any Acquisition
     Proposal being made and the Company's Board of Directors withdraws or
     materially modifies or changes its recommendation of this Agreement or the
     Merger if there exists at such time an Acquisition Proposal for the Company
     deemed to be a Superior Proposal and after written notice is given to
     Parent of the intent to accept a competing Acquisition Proposal and Parent
     has not communicated in writing within five (5) business days after receipt
     of such notice an Acquisition Proposal that matches or is more favorable
     than the third party Acquisition Proposal from a financial point of view;
     or
 
          (iii) the Parent Share Price is less than $52.00.
 
10.2 EFFECT OF TERMINATION.
 
          (a) In the event of the termination and abandonment of this Agreement
     pursuant to Section 10.1, this Agreement shall become void and have no
     effect, without any liability on the part of any party hereto or its
     affiliates, directors, officers or stockholders, provided that,
     notwithstanding the foregoing, if this Agreement has been terminated, the
     provisions of Sections 6.17, 7.13 and 10.2; the last sentence of Section
     8.8; and Article 11, in its entirety, shall survive such termination and
     shall continue to be of binding effect.
 
          (b) In the event of the termination of this Agreement by (A) the
     Company pursuant to Section 10.1(d)(ii), or (B) the Company or Parent
     pursuant to Section 10.1(b)(iii) due to the failure of the Company's
     stockholders to approve and adopt this Agreement, or (C) Parent pursuant to
     Section 10.1(c)(ii) and in the case of (B) or (C) above there exists an
     Acquisition Proposal for the Company, then the Company shall pay Parent
     $10,960,867. Any payment required to be paid pursuant to Section 10.2(b)(A)
     shall be made
 
                                      A-26
<PAGE>   92
 
     prior to, and shall be a pre-condition to the effectiveness of the
     termination of this Agreement pursuant to such Section. Any payment
     required to be paid pursuant to Section 10.2(b)(B) or Section 10.2(b)(C)
     shall be made to Parent not later than ten (10) days after the entering of
     a definitive agreement with respect to an Acquisition Proposal.
 
                                   ARTICLE 11
 
                               GENERAL PROVISIONS
 
11.1 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 and printing and mailing the Prospectus/Proxy
Statement and the S-4 Registration Statement and the filing fee under the HSR
Act shall be shared equally by Parent and the Company.
 
11.2 NONSURVIVAL. None of the representations, warranties, covenants and other
agreements in this Agreement or in any instrument delivered pursuant to this
Agreement, including any rights arising out of any breach of such
representations, warranties, covenants and other agreements, shall survive the
Effective Time, except for those covenants and agreements contained herein and
therein that by their terms apply or are to be performed in whole or in part
after the Effective Time and this Article 11. Nothing in this Section 11.2 shall
relieve any party for any breach of any representation, warranty, covenant or
other agreement in this Agreement occurring prior to termination.
 
11.3 MODIFICATION OR AMENDMENT. This Agreement may be amended by an instrument
in writing executed and delivered on behalf of each of the parties hereto, at
any time prior to the Effective Time, subject to the provisions of the DGCL;

the Company, no amendment shall be made which by Law requires further approval
by such stockholders without such further approval.
 
11.4 WAIVER. The conditions to each of the parties' obligations to consummate
the Merger are for the sole benefit of such party and may be waived, at any time
prior to the Effective Time, by such party in whole or in part to the extent
permitted by Law. Any agreement on the part of a party hereto to any extension
or waiver shall be valid only if set forth in writing signed on behalf of such
party, and shall not be inferred by the failure of any such party to assert any
of its rights hereunder. Waiver of any provision of this Agreement or of any
breach hereof shall be a waiver of only said specific provision or breach and
shall not be deemed a waiver of any other provision or any future breach hereof.

PERSONAL AND CONFIDENTIAL
 
Board of Directors
Unitog Company

Kansas City, MO 64105
 
     Re: Fairness Opinion
 
Gentlemen:
 
In connection with the proposed acquisition through a merger (the "Merger") by
Cintas Corporation ("Cintas" or "Parent") of Unitog Company ("Unitog" or the
"Company"), pursuant to the Agreement and Plan of Merger dated January 9, 1999
(the "Agreement") between Cintas, Cintas Image Acquisition Company ("Merger
Sub"), and Unitog you have requested our opinion as to the fairness, from a
financial point of view, to the Company's shareholders of the Merger
Consideration to be received by such shareholders for their common stock in the
proposed Merger pursuant to the Agreement.
 
Subject to the provisions of the Agreement, at the Effective Time, each issued
and outstanding share of common stock of the Company ("Company Shares"), by
virtue of the Merger and without any action on the part of the holder thereof,
other than Company Shares owned by Parent, Merger Sub, or any direct or indirect
wholly owned subsidiary of Parent, shall be converted into the right to receive
as Merger Consideration, that number of shares of Parent Common Stock equal to
the Conversion Number upon surrender of the Certificate representing such
Company Share.
 
The Conversion Number shall be equal to the quotient (rounded to the nearest
1/10,000) determined by dividing $38.00, as adjusted pursuant to Section 8.3 of
the Agreement ("Company Share Price"), by the amount determined by calculating
the average of the high and low sales prices of Parent Common Stock as reported
on the NASDAQ Stock Market for the twenty (20) consecutive trading days ending
on the third trading day preceding the date of the meeting of the Company's
stockholders for the purpose of voting on the adoption of this Agreement
("Parent Share Price"). Notwithstanding the foregoing, if the Parent Share Price
is less than $52.00, the Parent Share Price shall be deemed to be $52.00 (for
purposes of determining the Conversion Number) and, if the Parent Share Price is
greater than $66.43, the Parent Share Price shall be deemed to be $66.43 plus
fifty percent (50%) of the difference between the Parent Share Price and $66.43.
 
As a customary part of its investment banking business, Goldsmith, Agio, Helms
Securities, Inc. ("GAHS") is engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, private placements, and
valuations for estate, corporate, and other purposes. In return for our services
in connection with providing this opinion, the Company will pay us a fee, which
fee is not contingent upon the consummation of the Merger, and indemnify us
against certain liabilities. We are also acting as a financial advisor to the
Company in connection with the Merger for which we will receive certain other
fees, a significant portion of which is contingent upon the consummation of the
Merger.
 
In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have (i) reviewed the Agreement; (ii) analyzed financial and
other information that is publicly available relating to Cintas; (iii) analyzed
financial and other information that is publicly available relating to the
Company; (iv) analyzed certain financial and operating data of the Company that
has been made available to us by Unitog; (v) visited certain facilities of the
Company and discussed with management of the Company the financial condition,
operating results, business outlook and

prospects of the Company; (vi) analyzed the valuations of publicly traded
companies that we deemed comparable to the Company; (vii) performed a discounted
cash flow analysis of the Company based on financial projections that Unitog
management provided to us; and (viii) analyzed the financial terms of certain
transactions we deemed similar to the Merger that have recently been effected.
 
We have relied upon and assume the accuracy, completeness, and fairness of the
financial statements and other information furnished by, or publicly available
relating to, the Company or Cintas, or otherwise made available to us, and have
not assumed responsibility independently to verify such information. We have
further relied upon assurances by the Company that the information provided to
us has a reasonable basis, and with respect to projections and other business
outlook information, reflects the best currently available estimates, and that
the Company is not aware of any information or fact that would make the
information provided to us incomplete or misleading. In arriving at our opinion,
we have not performed any appraisals or valuations of specific assets or
liabilities of the Company or Cintas and express no opinion regarding the
liquidation value of the Company or Cintas or any of its assets. Our opinion is
based upon the information available to us and the facts and circumstances as
they exist and are subject to evaluation on the date hereof; events occurring
after the date hereof could materially affect the assumptions used in preparing
this opinion.
 
We have assumed that the Merger will be accounted for as a pooling of interests
in accordance with generally accepted accounting principles ("GAAP") and that
such Merger qualifies for such accounting treatment under GAAP. We have also
assumed that the Merger will constitute a reorganization under Section 368 of
the Internal Revenue Code of 1986, as amended. We have relied, with respect to
legal and accounting matters related to the Agreement, on the advice of the
Company's legal and accounting advisors. We have made no independent
investigation of any legal or accounting matters that may affect the Company and
have assumed the correctness of the legal and accounting advice provided to the
Company and its Board of Directors.
 
Our opinion is rendered for the benefit and use of the Board of Directors of the
Company in connection with the Board's consideration of the Merger and does not
constitute a recommendation to any holder of Company Common Stock as to how such
stockholder should vote with respect to the Agreement. We have not been asked
to, nor do we, express an opinion as to the relative merits of the Merger as
compared to any alternative business strategies that might exist for the Company
or the effect of any other transaction in which the Company might engage. This
opinion may not be published or otherwise used or referred to publicly without
our written consent; provided, however, that this opinion may be included in its
entirety in any filing with the Securities and Exchange Commission with respect
to the Merger.
 
Based upon and subject to the foregoing, and based upon such other facts as we
consider relevant, it is our opinion that, as of the date hereof, the Merger
Consideration to be received by the Company's shareholders for their common
stock in the proposed Merger pursuant to the Agreement is fair to such
shareholders from a financial point of view.
 
                                        Sincerely,
 
   
                                        Goldsmith, Agio, Helms Securities, Inc.

PERSONAL AND CONFIDENTIAL
 
Board of Directors
Unitog Company
1300 Washington Street
Kansas City, Missouri 64105
 
Gentlemen:
 
You have requested our opinion as to the fairness from a financial point of view
to the holders of common stock of Unitog Company (the "Company") of the
consideration to be received by such holders pursuant the terms and conditions
set forth in the Agreement and Plan of Merger by and among Cintas Corporation
("Cintas"), Cintas Image Acquisition Company ("Merger Sub") and the Company,
dated January 9, 1999 (the "Agreement"). Pursuant to the Agreement, Merger Sub
will be merged with and into the Company (the "Merger") and each outstanding
share of the common stock, par value $0.01 per share, of the Company (the
"Company Common Stock") will be converted into the right to receive as merger
consideration (the "Merger Consideration") that number of shares of Cintas
common stock, no par value per share, (the "Cintas Common Stock") equal to the
conversion number (the "Conversion Number"), as hereinafter defined.
 
The Conversion Number means the quotient (rounded to the nearest 1/10,000th)
determined by dividing $38.00, as adjusted pursuant to Section 8.3 of the
Agreement ("Company Share Price"), by the amount determined by calculating the
average of the high and low sales prices of Cintas Common Stock as reported on
the NASDAQ Stock Market for the 20 consecutive trading days ending on the third
day preceding the date of the meeting of the Company's stockholders for the
purpose of voting on the adoption of the Agreement ("Cintas Share Price").
Notwithstanding the foregoing, if Cintas Share Price is less than $52.00, the
Cintas Share Price shall be deemed to be $52.00 (for purposes of determining the
Conversion Number) and, if the Cintas Share Price is greater than $66.43, the
Cintas Share Price shall be deemed to be $66.43 plus fifty percent (50%) of the
difference between the Cintas Share Price and $66.43 (for purposes of
determining the Conversion Number).
 
George K. Baum & Company ("Baum"), as part of its investment banking business,
is engaged in the valuation of businesses and their securities in connection
with mergers and acquisitions, negotiated underwritings, secondary distributions
of listed and unlisted securities, private placements and valuations for estate,
corporate and other purposes.
 
In connection with this opinion, we have reviewed, among other things, the
Agreement; certain publicly available business and financial information
relating to the Company and Cintas including the Company's and Cintas's recent
Annual Reports, Forms 10-K, Forms 10-Q, and other filings with the Securities
and Exchange Commission ("SEC"); and certain internal financial analyses and
forecasts prepared by the Company's management. We also have held discussions
with members of senior management of the Company regarding the past and current
business operations, financial condition and future prospects of the Company. In
addition, we have reviewed the reported price and trading activity for the
Company Common Stock and Cintas Common Stock, compared certain publicly
available financial and stock market information for the Company with similar
information for Cintas and certain other companies that we believe to be
comparable in certain respects to the Company and Cintas, reviewed the financial
terms of certain business combinations that we deemed to be similar to the
Merger, reviewed certain recent historical data relating to premiums paid in
mergers and acquisitions of publicly traded companies, and performed such other
studies and analyses as we deemed appropriate.
 
In preparing our opinion, we have relied upon and assumed the accuracy and
completeness of all the financial and other information that was publicly
available or provided to us by or on behalf of the Company and Cintas, and
<PAGE>   99
Unitog Company

Page  2
 
have not been engaged to independently verify any such information. We have not
undertaken nor obtained any independent evaluations or appraisals of any of the
Company's or Cintas's assets, properties, or liabilities, nor have we made any
physical inspection of the properties or assets of the Company or Cintas. We
have assumed that the Merger will be accounted for as a pooling of interests in
accordance with generally accepted accounting principles ("GAAP") and that such
Merger qualifies for such accounting treatment under GAAP. We have also assumed
that the Merger will constitute a tax-deferred reorganization pursuant to the
Internal Revenue Code of 1986, as amended. We have not been engaged to
independently verify any legal and accounting matters relative to the Agreement,
but instead have relied on the advice of the Company's legal and accounting
advisors.
 
We are acting as a financial advisor to the Company in connection with the
Merger for which we will receive certain fees, a significant portion of which,
but none of the fee relating to this opinion, is contingent upon the
consummation of the Merger. Additionally, Baum has previously rendered financial
advisory and investment banking services to the Company for which we have
received customary compensation. A member of the Company's Board of Directors is
a vice president of Baum and a director and officer of George K. Baum Group,
Inc., a holder of 661,870 shares of Company Common Stock, and another member of
the Company's Board of Directors is an employee of Baum and a director, officer
and shareholder of George K. Baum Group, Inc. In the ordinary course of
securities business, we and our affiliates may hold or actively trade the
securities of the Company or Cintas for our own account and for the accounts of
our customers and, accordingly, may at any time hold a long or short position in
such securities. Additionally, Baum makes a market in the Company's Common Stock
on the NASDAQ Stock Market.
 
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 Merger and such opinion does not
constitute a recommendation as to how any holder of Company Common Stock should
vote with respect to such transaction. This opinion is for the information of
the Board of Directors of the Company only in connection with its consideration
of the Agreement and may not be published or otherwise used by the Company
without our prior written consent; provided, however, that this opinion may be
included in its entirety in any filing with the SEC with respect to the Merger.
Our opinion necessarily is based on the conditions and circumstances as they
exist and can be evaluated as of the date hereof. We have not been asked to, nor
do we, express an opinion as to the relative merits of the Merger as compared to
any alternative business strategies that might exist for the Company or the
effect of any other transaction in which the Company might engage.
 
   
Based upon and subject to the foregoing, we are of the opinion that, as of the
date hereof, the proposed Merger Consideration to be received by the holders of
the Company Common Stock pursuant to the Agreement is fair from a financial
point of view to such holders.
    
 
   
                                        Very truly yours,

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Washington Business Corporation Act, Section 23A.08.025, allows
indemnification by the Registrant to any person made or threatened to be made a
party to any proceedings, other than a proceeding by or in the right of the
Registrant, by reason of the fact that he is or was a director, officer,
employee or agent of the Registrant, against expenses, including judgments and
fines, if he acted in good faith and in a manner reasonably believed to be in or
not opposed to the best interests of the Registrant and, with respect to
criminal actions, in which he had no reasonable cause to believe that his
conduct was unlawful. Similar provisions apply to actions brought by or in the
right of the Registrant, except that no indemnification shall be made in
proceedings in which the person shall have been adjudged to be liable to the
Corporation. Indemnifications are to be made by a majority vote of a quorum of
disinterested directors or the written opinion of independent counsel or by the
Shareholders.
 
     Article V of the Registrant's By-Laws provides that indemnification shall
be extended to any of the persons described above to the full extent permitted
by the Washington Business Corporation Act.

ITEM 22.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes as follows:
 
     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,
 
          (ii) to reflect in the prospectus any facts or events arising after
     the effective date of the Registration Statement for the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total 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
 
                                      II-1
<PAGE>   101
 
     in the maximum aggregate offering price set forth in the "Calculation of
     Registration Fee" taking 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.
 
     2. That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
     3. To remove from registration by means of post-effective amendment any of
the securities being registered which remain unsold in the termination of the
offering.
 
     4. 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.
 
     5. To supply by means of a post-effective amendment all information
concerning a transaction, and the Company being acquired involved therein, that
was not the subject of and included in the Registration Statement when it became
effective.
 
     6. That for purposes of determining any liability under the Securities Act
of 1933, each filing of the registrant's annual report pursuant to Section 13(a)
or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     7. Prior to any public reoffering of the securities registered hereunder
through use of a prospectus which is a part of this registration statement, by
any person or party who is deemed to be an underwriter within the meaning of
Rule 145(c), the issuer undertakes that such reoffering prospectus will contain
the information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
     8. That every prospectus (i) that is filed pursuant to paragraph 7
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Act and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     9. 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 (other than insurance), 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, other than indemnification pursuant to court order
and not including any coverage under, or agreement to pay premiums for, any
policy of insurance, is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
