Item 5.           Other Events

                  United Air Specialists, Inc. (the "Company") announced on
                  September 24, 1996 that it had entered into an Agreement and
                  Plan of Merger (the "Merger Agreement") with CUAS, Inc., a
                  Delaware corporation and wholly-owned subsidiary of CLARCOR
                  Inc. ("CUAS"), and CLARCOR Inc. ("CLARCOR"), a Delaware
                  corporation, pursuant to which CUAS will merge with and into
                  the Company with the Company as the surviving corporation (the
                  "Merger"). After consummation of the Merger, the Company will
                  become a wholly-owned subsidiary of CLARCOR. The Merger is
                  subject to certain contingencies set forth in the Merger
                  Agreement.

                  Pursuant to the Merger Agreement, each share of the Company's
                  Common Stock, without par value ("UAS Common Stock"),
                  outstanding immediately prior to the Effective Time (as
                  defined in the Merger Agreement) of the Merger (other than
                  shares owned directly or indirectly by CLARCOR or UAS, which
                  shares will be canceled) will be converted into .3698577 (the
                  "Conversion Number") of a share of Common Stock, par value $1
                  per share, of CLARCOR ("CLARCOR Common Stock"), including the
                  corresponding number of rights to purchase shares of Series B
                  Junior Participating Preferred Stock of CLARCOR. The
                  Conversion Number is subject to adjustment based on the number
                  of fully diluted shares of UAS Common Stock outstanding
                  immediately prior to the Effective Time. In addition, each
                  outstanding stock option to acquire a share of UAS Common
                  Stock will become an option to acquire the Conversion Number
                  of a share of CLARCOR Common Stock at an adjusted exercise
                  price equal to the current exercise price divided by the
                  Conversion Number. All other terms and conditions relating to
                  such options shall remain the same.

                  Each holder of a certificate representing prior to the
                  Effective Time shares of UAS Common Stock will cease to have
                  any rights with respect thereto after the Merger, except the
                  right to receive (i) certificate(s) representing the shares of
                  CLARCOR Common Stock into which such shares of UAS Common
                  Stock will have been converted, (ii) certain dividends and
                  other distributions previously withheld in accordance with
                  Section 1.7 of the Merger Agreement pending the exchange of
                  stock certificate(s) and (iii) any cash, without interest, to
                  be paid in lieu of any fractional share of CLARCOR Common
                  Stock in accordance with Section 1.8 of the Merger Agreement.
                  Notwithstanding the foregoing, holders of UAS Common Stock
                  will be entitled to appraisal rights in accordance with
                  applicable Ohio law.

                  Prior to its execution, the Merger Agreement was approved by
                  the respective Boards of Directors of CLARCOR and the Company.
                  A fairness opinion was delivered by J.J.B. Hilliard, W.L.
                  Lyons Inc. to the Board of Directors of the Company. The
                  consummation of the Merger is subject, among other things, to
                  the approval of the Merger by the Company's shareholders and
                  to certain regulatory approvals.

                  Concurrently with the execution of the Merger Agreement, the
                  holders of approximately 50% of the outstanding shares of UAS
                  Common Stock entered into stockholder agreements with CLARCOR
                  in which such stockholders agreed to vote their shares in
                  favor of the Merger and the Merger Agreement at a special
                  meeting of the UAS stockholders to be convened in connection
                  with the proposed Merger. Such Company stockholders further
                  agreed, among other things, not to enter into any agreement or
                  understanding that is inconsistent with the consummation of
                  the Merger and not to solicit, initiate or encourage any
                  person to make an offer or proposal that could lead to such
                  person acquiring 20% or more of the outstanding shares of UAS
                  Common Stock.

                  A copy of the Merger Agreement, the material exhibits thereto,
                  the stockholder agreements and the press release issued by the
                  Company announcing the execution of the Merger Agreement are
                  attached as exhibits hereto.

                          AGREEMENT AND PLAN OF MERGER

                  AGREEMENT AND PLAN OF MERGER dated as of September 23, 1996
(this "Agreement") among CLARCOR Inc., a Delaware corporation ("Parent"), CUAC
Inc., an Ohio corporation and a wholly-owned subsidiary of Parent ("Sub"), and
United Air Specialists, Inc., an Ohio corporation (the "Company") (Sub and the
Company being hereinafter collectively referred to as the "Constituent
Corporations").

                              W I T N E S S E T H:

                  WHEREAS, the respective Boards of Directors of Parent, Sub and
the Company have approved and declared advisable the merger of Sub into the
Company (the "Merger"), upon the terms and subject to the conditions herein set
forth, whereby each issued and outstanding share of Common Stock, without par
value, of the Company ("Company Common Shares"), not owned directly or
indirectly by Parent or the Company, will be converted into shares of Common
Stock, par value $1 per share, of Parent ("Parent Common Stock");

                  WHEREAS, the respective Boards of Directors of Parent and the
Company have determined that the Merger is in furtherance of and consistent with
their respective long-term business strategies and is fair to and in the best
interests of their respective stockholders;
<PAGE>   9
                  WHEREAS, for federal income tax purposes, it is intended that
the Merger shall qualify as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code"); and

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

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

                                    ARTICLE I

                                   THE MERGER

                  Section 1.1 The Merger. Upon the terms and subject to the
conditions herein set forth, and in accordance with the General Corporation Law
of the State of Ohio (the "OGCL"), Sub shall be merged with and into the Company
at the Effective Time (as hereinafter defined). Following the Merger, the
separate corporate existence of Sub shall cease and the Company shall continue
as the surviving corporation (the "Surviving Corporation") and shall succeed to
and assume all the rights and obligations of Sub in accordance with the OGCL.
Notwithstanding any provision of this Agreement to the contrary, at the election
of Parent, any direct wholly-owned Subsidiary (as hereinafter defined) of Parent
may be substituted for Sub as a constituent

                                       -2-
<PAGE>   10
corporation in the Merger. In such event, the parties hereto agree to execute an
appropriate amendment to this Agreement, in form and substance reasonably
satisfactory to Parent and the Company, in order to reflect such substitution.

                  Section 1.2 Effective Time. The Merger shall become effective
when a certificate of merger (the "Certificate of Merger"), executed in
accordance with the relevant provisions of the OGCL, is accepted for filing by
the Secretary of State of the State of Ohio; provided, however, that, upon the
mutual consent of the Constituent Corporations, the Certificate of Merger may
provide for a later date of effectiveness of the Merger, but not to exceed 30
days after the date that the Certificate of Merger is accepted for filing. When
used in this Agreement, the term "Effective Time" means the later of the date
and time at which the Certificate of Merger is accepted for filing or such later
date and time as is established by the Certificate of Merger. The filing of the
Certificate of Merger shall be made as soon as practicable after the
satisfaction or waiver of the conditions to the Merger herein set forth.

                  Section 1.3 Effects of the Merger. The Merger shall have the
effects set forth in Section 1701.82 of the OGCL.

                  Section 1.4 Articles of Incorporation and Regulations;
Officers and Directors. (a) The Articles of Incorporation of the Company, as in
effect immediately prior to the Effective Time, shall be amended at the
Effective Time as a result of the Merger so that the first sentence of Article
Fourth thereof reads in its entirety as follows: "The authorized capital stock
of the corporation shall be 1,000 shares of Common Stock, without par value". As
so amended, such

                                       -3-
<PAGE>   11
Articles of Incorporation shall be the Articles of Incorporation of the
Surviving Corporation until thereafter changed or amended as provided therein or
by applicable law.

                  (b) The Regulations of the Company, as in effect immediately
prior to the Effective Time, shall be the Regulations of the Surviving
Corporation at the Effective Time as a result of the Merger until thereafter
changed or amended as provided therein or in the Articles of Incorporation of
the Surviving Corporation or as provided by applicable law.

                  Section 1.5 Conversion of Securities. As of the Effective
Time, by virtue of the Merger and without any action on the part of any
shareholder of either of the Constituent Corporations:

                  (a) Each issued and outstanding share of Common Stock, par
         value $1 per share, of Sub shall be converted into one share of Common
         Stock of the Surviving Corporation.

                  (b) All Company Common Shares that are held in the treasury of
         the Company or by any wholly-owned Subsidiary of the Company and any
         Company Common Shares owned by Parent or by any wholly-owned Subsidiary
         of Parent shall be cancelled and no capital stock of Parent or other
         consideration shall be delivered in exchange therefor.

                  (c) Subject to the provisions of Sections 1.8 and 1.10, each
         Company Common Share issued and outstanding immediately prior to the
         Effective Time (other than shares

                                       -4-
<PAGE>   12
         to be cancelled in accordance with Section 1.5(b)) shall be converted
         into .3698577 (such number being hereinafter referred to as the
         "Conversion Number") shares of validly issued, fully paid and
         nonassessable Parent Common Stock, including the corresponding number
         of rights (such rights being hereinafter referred to collectively as
         the "Parent Rights") to purchase shares of Series B Junior
         Participating Preferred Stock of Parent (the "Parent Series B Preferred
         Stock") pursuant to the Stockholders Rights Agreement dated as of March
         28, 1996 (the "Parent Rights Agreement") between Parent and First
         Chicago Trust Company of New York, as Rights Agent. Prior to the
         Distribution Date (as defined in the Parent Rights Agreement), all
         references in this Agreement to Parent Common Stock to be received in
         accordance with the Merger shall be deemed to include the associated
         Parent Rights. All such Company Common Shares, when so converted, shall
         no longer be outstanding and shall automatically be cancelled and
         retired; and each holder of a certificate representing any such Company
         Common Shares shall cease to have any rights with respect thereto,
         except the right to receive (i) certificates representing the shares of
         Parent Common Stock into which such Company Common Shares have been
         converted, (ii) any dividends and other distributions in accordance
         with Section 1.7 and (iii) any cash, without interest, to be paid in
         lieu of any fractional share of Parent Common Stock in accordance with
         Section 1.8.

                  (d) Notwithstanding any other provisions of this Agreement to
the contrary, Company Common Shares that are outstanding immediately prior to
the Effective Time and which are held by shareholders who shall not have voted
in favor of the Merger or consented thereto in writing and who shall have
demanded properly in writing appraisal for such shares in accordance with
Section 1701.85 of the OGCL (collectively, the "Dissenting Shares") shall not

                                       -5-
<PAGE>   13
be converted into or represent the right to receive the consideration provided
in Section 1.5(c). Such shareholders shall be entitled to receive payment of the
appraised value of such Company Common Shares held by them in accordance with
the provisions of such Section 1701.85, except that all Dissenting Shares held
by shareholders who shall have failed to perfect or who effectively shall have
withdrawn or lost their rights to appraisal of such Company Common Shares under
such Section 1701.85 shall thereupon be deemed to have been converted into and
to have become exchangeable for, as of the Effective Time, the right to receive
the consideration, without any interest thereon, upon surrender of the
certificate or certificates that formerly evidenced such Company Common Shares
in the manner provided in Section 1.5(c).

                  Section 1.6 Parent to Make Stock Certificates Available. (a)
Exchange of Certificates. Parent shall authorize a commercial bank (or such
other person or persons as shall be acceptable to Parent and the Company) to act
as exchange agent hereunder (the "Exchange Agent"). As soon as practicable, but
not later than five business days after the Effective Time, Parent shall deposit
with the Exchange Agent, in trust for the holders of certificates (the "Company
Certificates") which immediately prior to the Effective Time represented Company
Common Shares converted in the Merger, certificates (the "Parent Certificates")
representing the shares of Parent Common Stock (such shares of Parent Common
Stock, together with any dividends or distributions with respect thereto in
accordance with Section 1.7, being hereinafter referred to as the "Exchange
Fund") issuable pursuant to Section 1.5(c) in exchange for the outstanding
Company Common Shares.

                                       -6-
<PAGE>   14
                  (b) Exchange Procedures. As soon as practicable after the
Effective Time, the Exchange Agent shall mail to each record holder of a Company
Certificate a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Company Certificates shall pass,
only upon actual delivery thereof to the Exchange Agent and shall contain
instructions for use in effecting the surrender of the Company Certificates in
exchange for the property described in the next sentence). Upon surrender for
cancellation to the Exchange Agent of all Company Certificate(s) held by any
record holder of a Company Certificate, together with such letter of transmittal
duly executed, such holder shall be entitled to receive in exchange therefor a
Parent Certificate representing the number of whole shares of Parent Common
Stock into which the Company Common Shares represented by the surrendered
Company Certificate(s) shall have been converted at the Effective Time pursuant
to this Article I, cash in lieu of any fractional share of Parent Common Stock
in accordance with Section 1.8 and certain dividends and other distributions in
accordance with Section 1.7; and the Company Certificate(s) so surrendered shall
forthwith be cancelled.

                  Section 1.7 Dividends; Transfer Taxes; Withholding. No
dividends or other distributions that are declared on or after the Effective
Time on Parent Common Stock, or are payable to the holders of record thereof on
or after the Effective Time, shall be paid to any person entitled by reason of
the Merger to receive Parent Certificates representing Parent Common Stock, and
no cash payment in lieu of any fractional share of Parent Common Stock shall be
paid to any such person pursuant to Section 1.8, until such person shall have
surrendered its Company Certificate(s) as provided in Section 1.6. Subject to
applicable law, there shall be paid to each person receiving a Parent
Certificate representing such shares of Parent Common Stock: (i) at the

                                       -7-
<PAGE>   15
time of such surrender or as promptly as practicable thereafter, the amount of
any dividends or other distributions theretofore paid with respect to the shares
of Parent Common Stock represented by such Parent Certificate and having a
record date on or after the Effective Time and a payment date prior to such
surrender; and (ii) at the appropriate payment date or as promptly as
practicable thereafter, the amount of any dividends or other distributions
payable with respect to such shares of Parent Common Stock and having a record
date on or after the Effective Time but prior to such surrender and a payment
date on or subsequent to such surrender. In no event shall the person entitled
to receive such dividends or other distributions be entitled to receive interest
on such dividends or other distributions. If any cash or Parent Certificate
representing shares of Parent Common Stock is to be paid to or issued in a name
other than that in which the Company Certificate surrendered in exchange
therefor is registered, it shall be a condition of such exchange that the
Company Certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange shall pay
to the Exchange Agent any transfer or other taxes required by reason of the
issuance of such Parent Certificate and the distribution of such cash payment in
a name other than that of the registered holder of the Company Certificate so
surrendered, or shall establish to the satisfaction of the Exchange Agent that
such tax has been paid or is not applicable. Parent or the Exchange Agent shall
be entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of Company Common Shares such amounts
as Parent or the Exchange Agent are required to deduct and withhold under the
Code, or any provision of state, local or foreign tax law, with respect to the
making of such payment. To the extent that amounts are so withheld by Parent or
the Exchange Agent, such withheld amounts shall be treated for all

                                       -8-
<PAGE>   16
purposes of this Agreement as having been paid to the holder of the Company
Common Shares in respect of whom such deduction and withholding was made by
Parent or the Exchange Agent.

                  Section 1.8 No Fractional Shares. No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Company Certificates pursuant to this Article I; no
dividend or other distribution by Parent and no stock split shall relate to any
such fractional share; and no such fractional share shall entitle the record or
beneficial owner thereof to vote or to any other rights of a stockholder of
Parent. In lieu of any such fractional share, each holder of Company Common
Shares who would otherwise have been entitled thereto upon the surrender of
Company Certificate(s) for exchange pursuant to this Article I will be paid an
amount in cash (without interest) rounded to the nearest whole cent, determined
by multiplying (i) the per share closing price on the New York Stock Exchange,
Inc. (the "NYSE") of Parent Common Stock (as reported in the NYSE Composite
Transactions) on the date on which the Effective Time shall occur (or, if the
Parent Common Stock shall not trade on the NYSE on such date, the first day of
trading in Parent Common Stock on the NYSE thereafter) by (ii) the fractional
share to which such holder would otherwise be entitled.

                  Section 1.9 Return of Exchange Fund. Any portion of the
Exchange Fund which remains undistributed to the former holders of Company
Common Shares for one year after the Effective Time shall be delivered to
Parent, upon its request, and any such former holders who have not theretofore
complied with this Article I shall thereafter look only to Parent for payment of
their claim for shares of Parent Common Stock, any cash in lieu of fractional
shares of Parent Common Stock and any dividends or distributions with respect to
such shares of Parent Common

                                       -9-
<PAGE>   17
Stock. Neither Parent nor the Company shall be liable to any former holder of
Company Common Shares for any such shares of Parent Common Stock held in the
Exchange Fund which is delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

                  Section 1.10 Adjustment of Conversion Number. In the event
that the sum of the aggregate number of Company Common Shares issued and
outstanding immediately prior to the Effective Time (other than shares to be
cancelled in accordance with Section 1.5(b)) and the aggregate number of Company
Common Shares issuable in connection with the Company Stock Options which are
outstanding immediately prior to the Effective Time pursuant to the Company
Stock Plans (as defined in Section 5.8) is either less than or greater than
3,269,641, then the Conversion Number shall be adjusted such that it will equal
the quotient, rounded up or down to the seventh decimal place, obtained by
dividing 1,209,302 by such sum, and all references in this Agreement to the
Conversion Number shall be deemed to be to the Conversion Number as so adjusted.
In addition, in the event of any reclassification, stock split or stock dividend
with respect to Parent Common Stock, any change or conversion of Parent Common
Stock into other securities or any other dividend or distribution with respect
to Parent Common Stock (other than normal quarterly cash dividends as the same
may be modified from time to time in the ordinary course), or if a record date
with respect to any of the foregoing should occur, prior to the Effective Time,
appropriate and proportionate adjustments shall be made to the Conversion
Number, and thereafter all references in this Agreement to the Conversion Number
shall be deemed to be to the Conversion Number as so adjusted.

                                      -10-
<PAGE>   18
                  Section 1.11 No Further Ownership Rights in Company Common
Stock. All shares of Parent Common Stock issued upon the surrender for exchange
of any Company Certificate in accordance with the terms hereof (including any
cash paid pursuant to Section 1.7 or 1.8) shall be deemed to have been issued
(and paid) in full satisfaction of all rights pertaining to the Company Common
Shares represented by such Company Certificate.

                  Section 1.12 Closing of Company Transfer Books. At the
Effective Time, the stock transfer books of the Company shall be closed, and no
transfer of Company Common Shares shall thereafter be made. If, after the
Effective Time, Company Certificates are presented to the Surviving Corporation,
they shall be cancelled and exchanged as provided in this Article I.

                  Section 1.13 Further Assurances. If, at any time after the
Effective Time, the Surviving Corporation shall consider or be advised that any
deeds, bills of sale, assignments or assurances or any other acts or things are
necessary, desirable or proper (i) to vest, perfect or confirm, of record or
otherwise, in the Surviving Corporation its right, title and interest in, to or
under any of the rights, privileges, powers, franchises, properties or assets of
either of the Constituent Corporations or (ii) otherwise to carry out the
purposes of this Agreement, the Surviving Corporation and its proper officers
and directors or their designees shall be authorized to execute and deliver, in
the name and on behalf of either Constituent Corporation, all such deeds, bills
of sale, assignments and assurances and to do, in the name and on behalf of
either Constituent Corporation, all such other acts and things as may be
necessary, desirable or proper to vest, perfect or confirm the Surviving
Corporation's right, title and interest in, to and under any

                                      -11-
<PAGE>   19
of the rights, privileges, powers, franchises, properties or assets of such
Constituent Corporation and otherwise to carry out the purposes of this
Agreement.

                  Section 1.14 Closing. The closing of the transactions
contemplated by this Agreement (the "Closing") shall take place at the offices
of Sidley & Austin, One First National Plaza, Chicago, Illinois at 10:00 a.m.,
local time, on the day on which the last of the conditions set forth in Article
VI shall have been fulfilled or waived, or at such other time and place as
Parent and the Company may agree, but in no event prior to the fifteenth day
after the date of the Company Stockholder Meeting (as hereinafter defined).

                                   ARTICLE II

                REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

                  Parent and Sub represent and warrant to the Company as

in good standing under the laws of the jurisdiction in which it is incorporated
and has the requisite corporate power and authority to carry on its business as
now being conducted. Parent and each of its Subsidiaries are duly qualified to
do business, and are in good standing, in each jurisdiction where the character
of their properties owned or held under lease or the nature of their activities
makes such qualification necessary, except where the failure to be so qualified
would not reasonably be expected to have, individually or in the aggregate, a
Material Adverse Effect on Parent. For purposes of this Agreement: (i) "Material
Adverse Change" or "Material Adverse Effect" means, when used with respect to
Parent or the Company, as the case may be, any change or effect that is or would
reasonably be expected (so far as can be foreseen at the time) to be materially
adverse to the business, properties, assets, liabilities, condition (financial
or otherwise) or results of operations of Parent and its Subsidiaries taken as a
whole, or the Company and its Subsidiaries taken as a whole, as the case may be;
provided, however, that (A) no Material Adverse Change or Material Adverse
Effect shall be deemed to have occurred by reason of a change or effect
resulting from general economic conditions, general industry conditions or a
general deterioration in the financial markets and (B) if the Company's results
of operations for the first and second quarters of fiscal year 1997 are not
materially less than the forecasted results of operations for such quarters set
forth in the forecasts previously delivered by the Company to Parent and
included in the Company Letter (as hereinafter defined), such results shall not
be considered to be a Material Adverse Change or a Material Adverse Effect; and
(ii) "Subsidiary" means any corporation, partnership, joint venture or other
legal entity of which Parent or the Company, as the case may be (either alone or
through or together with any other Subsidiary), owns, directly or indirectly,
50% or more of the capital stock or other equity interests the holders of which
are generally entitled to vote for the election of the board of

                                      -13-
<PAGE>   21
directors or other governing body of such corporation, partnership, joint
venture or other legal entity.

                  Section 2.2 Capital Structure. As of the date hereof, the
authorized capital stock of Parent consists of: 30,000,000 shares of Parent
Common Stock; and 1,300,000 shares of Preferred Stock, without par value (the
"Parent Preferred Stock"), of which 300,000 shares have been designated as
"Series B Junior Participating Preferred Stock" (the "Parent Series B Preferred
Stock"). At the close of business on August 30, 1996, 14,877,612 shares of
Parent Common Stock were issued and outstanding, all of which were validly
issued, are fully paid and nonassessable and are free of preemptive rights. No
shares of Parent Preferred Stock have been issued. All of the shares of Parent
Common Stock issuable in exchange for Company Common Shares at the Effective
Time in accordance with this Agreement will be, when so issued, duly authorized,
validly issued, fully paid and nonassessable and free of preemptive rights. As
of the date of this Agreement, except for this Agreement, except (a) as provided
in Parent's Restated Certificate of Incorporation, (b) for the Parent Rights,
and (c) except for stock options covering not in excess of 1,334,800 shares of
Parent Common Stock (collectively, the "Parent Stock Options"), there are no
options, warrants, calls, rights or agreements to which Parent or any of its
Subsidiaries is a party or by which any of them is bound obligating Parent or
any of its Subsidiaries to issue, deliver or sell, or cause to be issued,
delivered or sold, additional shares of capital stock of Parent or any such
Subsidiary or obligating Parent or any such Subsidiary to grant, extend or enter
into any such option, warrant, call, right or agreement. Each outstanding share
of capital stock of each Subsidiary of Parent is duly authorized, validly
issued, fully paid and nonassessable and, except as disclosed in the Parent SEC
Documents or the Parent Letter (as

                                      -14-
<PAGE>   22
such terms are hereinafter defined), each such share is beneficially owned by
Parent or another Subsidiary of Parent, free and clear of all security
interests, liens, claims, pledges, options, rights of first refusal, agreements,
limitations on voting rights, charges and other encumbrances of any nature
whatsoever. Exhibit 21 to Parent's Annual Report on Form 10-K for the fiscal
year ended December 2, 1995, as filed with the Securities and Exchange
Commission (the "SEC") (the "Parent Annual Report"), is a true, accurate and
correct statement in all material respects of all of the information required to
be set forth therein by the regulations of the SEC.

                  Section 2.3 Authority. The Board of Directors of Parent has
declared as advisable and fair to and in the best interests of the stockholders
of Parent the Merger, and the issuance (the "Parent Share Issuance") of shares
of Parent Common Stock in accordance with the Merger and has approved this
Agreement. The Board of Directors and sole shareholder of Sub has approved this
Agreement. Parent has all requisite power and authority to enter into this
Agreement and to consummate the transactions contemplated hereby. Sub has all
requisite power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by Parent and Sub and the consummation by Parent and Sub of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Parent and Sub. This Agreement has been duly executed and
delivered by Parent and Sub and (assuming the valid authorization, execution and
delivery thereof by the Company and the validity and binding effect thereof on
the Company) constitutes the valid and binding obligation of Sub and Parent,
enforceable against Sub and Parent in accordance with its terms. The Parent
Share Issuance and the filing of a registration statement on Form S-4 with the
SEC by Parent under the Securities Act of 1933, as

                                      -15-
<PAGE>   23
amended (together with the rules and regulations promulgated thereunder, the
"Securities Act"), for the purpose of registering the shares of Parent Common
Stock to be issued in connection with the Merger (together with any amendments
or supplements thereto, whether prior to or after the effective date thereof,
the "Registration Statement") have been duly authorized by Parent's Board of
Directors.

                  Section 2.4 Consents and Approvals; No Violation. Except as
set forth in the letter dated and delivered to the Company on the date hereof
(the "Parent Letter"), which relates to this Agreement and is designated therein
as being the Parent Letter, the execution and delivery of this Agreement do not,
and the consummation of the transactions contemplated hereby and compliance with
the provisions hereof will not, result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give rise to a right of
termination, cancellation or acceleration of any obligation or to the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of Parent
or any of its Subsidiaries under: (i) any provision of the Restated Certificate
of Incorporation or By-laws of Parent or the comparable charter or organization
documents or by-laws of any of its Subsidiaries as amended, (ii) any loan or
credit agreement, note, bond, mortgage, indenture, lease, agreement, instrument,
permit, concession, franchise or license applicable to Parent or any of its
Subsidiaries or (iii) any judgment, order, decree, statute, law, ordinance, rule
or regulation applicable to Parent or any of its Subsidiaries or any of their
respective properties or assets, other than, in the case of clauses (ii) and
(iii), any such violations, defaults, rights, liens, security interests, charges
or encumbrances that, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect on Parent and

                                      -16-
<PAGE>   24
would not materially impair the ability of Parent or Sub to perform their
respective obligations hereunder or prevent the consummation of any of the
transactions contemplated hereby. No filing or registration with, or
authorization, consent or approval of, any domestic (federal and state), foreign
or supranational court, commission, governmental body, regulatory agency,
authority or tribunal (a "Governmental Entity") is required by or with respect
to Parent or any of its Subsidiaries in connection with the execution and
delivery of this Agreement by Sub and Parent or is necessary for the
consummation of the Merger and the other transactions contemplated by this
Agreement, except: (i) in connection, or in compliance, with the provisions of
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), the Securities Act and the Securities Exchange Act of 1934, as amended
(together with the rules and regulations promulgated thereunder, the "Exchange
Act"), (ii) for the filing of the Certificate of Merger with the Secretary of
State of the State of Ohio, (iii) for such consents, approvals, orders,
authorizations, 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 property or assets and (iv) for such other
consents, orders, authorizations, registrations, declarations and filings the
failure of which to obtain or make would not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on Parent and would not
materially impair the ability of Parent or Sub to perform their respective
obligations hereunder or prevent the consummation of any of the transactions
contemplated hereby.

                  Section 2.5 SEC Documents and Other Reports. Parent has filed
all required documents with the SEC since January 1, 1991 (the "Parent SEC
Documents"). As of their respective dates, the Parent SEC Documents complied in
all material respects with the

                                      -17-
<PAGE>   25
requirements of the Securities Act or the Exchange Act, as the case may be, and
none of the Parent SEC Documents contained any untrue statement of a material
fact or omitted to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. The consolidated financial statements of
Parent included in the Parent SEC Documents complied as to form in all material
respects with the applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto, have been prepared in accordance
with generally accepted account ing principles (except, in the case of the
unaudited statements, as permitted by Form 10-Q of the SEC) applied on a
consistent basis during the periods involved (except as may be indicated therein
or in the notes thereto) and fairly present the consolidated financial position
of Parent and its consolidated Subsidiaries as at the respective dates thereof
and the consolidated results of their operations and their consolidated cash
flows for the respective periods then ended (subject, in the case of the
unaudited statements, to normal year-end audit adjustments and to any other
adjustments described therein). Since December 2, 1995, Parent has not made any
change in the accounting practices or policies applied in the preparation of its
financial statements.

                  Section 2.6 Registration Statement and Proxy Statement. None
of the information to be supplied by Parent or Sub for inclusion or
incorporation by reference in the Registration Statement or the proxy
statement/prospectus included therein (together with any amendments or
supplements thereto, the "Proxy Statement") relating to the Company Stockholder
Meeting (as defined in Section 5.1) will (i) in the case of the Registration
Statement, at the time it becomes effective, 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

                                      -18-

under which they are made, not misleading. If at any time prior to the Effective
Time any event with respect to Parent, its directors and officers or any of its
Subsidiaries shall occur which is required to be described in the Proxy
Statement or the Registration Statement, such event shall be so described, and
an appropriate amendment or supplement shall be promptly filed with the SEC and,
to the extent required by law, disseminated to the shareholders of the Company.
The Registration Statement will comply (with respect to Parent) as to form in
all material respects with the provisions of the Securities Act, and the Proxy
Statement will comply (with respect to Parent) as to form in all material
respects with the provisions of the Exchange Act.

disclosed in the Parent SEC Documents or the Parent Letter, since December 2,
1995: (i) Parent and its Subsidiaries have not incurred any material liability

and its Subsidiaries, no change in the outstanding shares of capital stock of
Parent except for the

                                      -19-
<PAGE>   27
issuance of shares of Parent Common Stock pursuant to the Parent Stock Options
and no dividend or distribution of any kind declared, paid or made by Parent on
any class of its capital stock except for regular quarterly dividends of not
more than $0.1625 per share on Parent Common Stock and (iv) there has been no
event causing a Material Adverse Effect on Parent, nor any development that
would, individually or in the aggregate, reasonably be expected to result in a
Material Adverse Effect on Parent; and except as set forth in the Parent Letter,
during the period from December 2, 1995 through the date of this Agreement,
neither Parent nor any of its Subsidiaries has taken any action that, if taken
during the period from the date of this Agreement through the Effective Time,
would constitute a breach of Section 4.1(a).

                  Section 2.8 No Existing Violation, Default, Etc. Neither
Parent nor any of its Subsidiaries is in violation of (i) its charter or other
organization documents or by-laws, (ii) any applicable law, ordinance or
administrative or governmental rule or regulation or (iii) any order, decree or
judgment of any Governmental Entity having jurisdiction over Parent or any of
its Subsidiaries, except for any violations that, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
Parent. The properties, assets and operations of Parent and its Subsidiaries are
in compliance in all material respects with all applicable federal, state, local
and foreign laws, rules and regulations, orders, decrees, judgments, permits and
licenses relating to public and worker health and safety (collectively, "Worker
Safety Laws") and the protection and clean-up of the environment and activities
or conditions related thereto, including, without limitation, those relating to
the generation, handling, disposal, transportation or release of hazardous
materials (collectively, "Environmental Laws"), except for any violations that,
individually or in the aggregate, would not reasonably be expected to have a

                                      -20-
<PAGE>   28
Material Adverse Effect on Parent. With respect to such properties, assets and
operations, including any previously owned, leased or operated properties,
assets or operations, there are no past, present or reasonably anticipated
future events, conditions, circumstances, activities, practices, incidents,
actions or plans of Parent or any of its Subsidiaries that may interfere with or
prevent compliance or continued compliance in all material respects with
applicable Worker Safety Laws and Environmental Laws, other than any such
interference or prevention as would not, individually or in the aggregate with
any such other interference or prevention, reasonably be expected to have a
Material Adverse Effect on Parent. The term "hazardous materials" shall mean
those substances that are regulated by or form the basis for liability under any
applicable Environmental Laws.

                  Except as may be set forth in the Parent SEC Documents or the
Parent Letter, prior to the date of this Agreement, no event of default or event
that, but for the giving of notice or lapse of time, or both, would constitute
an event of default exists or, upon the consummation by Parent of the
transactions contemplated by this Agreement, will exist under any loan or credit
agreement, note, bond, mortgage, indenture or guarantee of indebtedness for
borrowed money or any other material lease, agreement or instrument to which
Parent or any of its Subsidiaries is a party or by which Parent or any such
Subsidiary or any of their respective properties, assets or business is bound.

                  Section 2.9 Licenses and Permits. Parent and its Subsidiaries
have received such certificates, permits, licenses, franchises, consents,
approvals, orders, authorizations and clearances from appropriate Governmental
Entities (the "Parent Licenses") as are necessary to

                                      -21-
<PAGE>   29
own or lease and operate their respective properties and to conduct their
respective businesses substantially in the manner described in the Parent SEC
Documents and as currently owned or leased and conducted, and all such Parent
Licenses are valid and in full force and effect, except for any such
certificates, permits, licenses, franchises, consents, approvals, orders,
authorizations and clearances which the failure to have or to be in full force
and effect would not reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect on Parent. Parent and its Subsidiaries are
in compliance in all material respects with their respective obligations under
the Parent Licenses, with only such exceptions as, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
Parent, and no event has occurred that allows, or after notice or lapse of time,
or both, would allow, revocation or termination of any material Parent License.

                  Section 2.10 Environmental Matters. Except as set forth in the
Parent SEC Documents or the Parent Letter, neither Parent nor any of its
Subsidiaries is the subject of any federal, state, local, foreign or provincial

to have a Material Adverse Effect on Parent; and there are no pending,
reasonably anticipated or, to the knowledge of Parent, threatened actions, suits
or proceedings against or affecting Parent, any of its Subsidiaries or any of
their respective properties, assets or operations asserting any such liability
or seeking any such

                                      -22-
<PAGE>   30
remedial action in connection with any Environmental Laws that would reasonably
be expected to have a Material Adverse Effect on Parent.

                  Section 2.11 Tax Matters. Except as otherwise set forth in the
Parent Letter: (i) Parent and each of its Subsidiaries have filed all federal,
and all material state, local and foreign, Tax Returns (as hereinafter defined),
required to have been filed on or prior to the date hereof or appropriate
extensions therefor have been properly obtained; (ii) all Taxes (as hereinafter
defined), shown to be due on such Tax Returns have been timely paid or
extensions for payment have been duly obtained, or such Taxes are being timely
and properly contested; (iii) neither Parent nor any of its Subsidiaries has
waived any statute of limitations in respect of its Taxes; (iv) any such Tax
Returns relating to federal and state income Taxes have been audited by the
Internal Revenue Service or the appropriate state taxing authority or the period
for assessment of the Taxes in respect of which such Tax Returns were required
to be filed has expired; (v) no issues that have been raised in writing by the
relevant taxing authority in connection with the audit of such Tax Returns are
currently pending; and (vi) all deficiencies asserted or assessments made as a
result of any audit of such Tax Returns by any taxing authority have been paid

foreign income, gross receipts, property, sales, use, license, excise,
franchise, employment, payroll, withholding, alternative or add-on minimum, ad

<PAGE>   31
any Tax, including, without limitation, any information return, claim for
refund, amended return or declaration of estimated Tax. The charges, accruals
and reserves on the books of Parent and its Subsidiaries in respect of Taxes and
other governmental charges are adequate. To the knowledge of Parent, the
representations set forth in the Parent Tax Certificate (as defined in Section
6.2(b)) attached to the Parent Letter are true and correct in all material
respects.

                  Section 2.12 Actions and Proceedings. Except as set forth in
the Parent SEC Documents or the Parent Letter, there are no outstanding orders,
judgments, injunctions, awards or decrees of any Governmental Entity against or
affecting Parent or any of its Subsidiaries, any of its or their current or
former directors, officers, employees, consultants, agents or stockholders, as
such, any of its or their properties, assets or business or any Parent Plan (as
defined in Section 2.15) that would reasonably be expected to have, individually
or in the aggregate, a Material Adverse Effect on Parent. Except as set forth in
the Parent Letter, there are no actions, suits or claims or legal,
administrative or arbitration proceedings or investigations pending or, to the
knowledge of Parent, threatened against or affecting Parent or any of its
Subsidiaries, any of its or their current or former directors, officers,

properties, assets or business or any Parent Plan that if brought (if not now
pending) would reasonably be expected to have, individually or in the aggregate,
a Material Adverse Effect on Parent. There are no actions, suits or claims or
legal, administrative or arbitration proceedings or investigations or labor
disputes pending or, to the knowledge of Parent, threatened against or affecting
Parent or any of its Subsidiaries, any of its or their current or former
directors, officers,

                                      -24-
<PAGE>   32
employees, consultants, agents or stockholders, as such, any of its or their
properties, assets or business or any Parent Plan relating to the transactions
contemplated by this Agreement.

                  Section 2.13 Labor Matters. Except as disclosed in the Parent
SEC Documents or the Parent Letter, neither Parent nor any of its Subsidiaries
has any labor contracts, collective bargaining agreements or material employment
or consulting agreements with any persons employed by or otherwise performing
services primarily for Parent or any of its Subsidiaries (the "Parent Business

any of its Subsidiaries has engaged in any unfair labor practice with respect to
Parent Business Personnel, and there is no unfair labor practice complaint
pending against Parent or any of its Subsidiaries with respect to Parent
Business Personnel. There is no labor strike, dispute, slowdown or stoppage
pending or, to the knowledge of Parent, threatened against or affecting Parent
or any of its Subsidiaries that would reasonably be expected to have a Material
Adverse Effect on Parent, and neither Parent nor any of its Subsidiaries has
experienced any primary work stoppage or other material labor difficulty
involving its employees during the last five years that has had or would
reasonably be expected to have a Material Adverse Effect on Parent. Parent is in
compliance with the requirements of the Workers Adjustment and Retraining
Notification Act (the "WARN Act") and has no liabilities pursuant to the WARN
Act.

                  Section 2.14 Contracts. All of the material contracts of
Parent and its Subsidiaries that are required to be described in the Parent SEC
Documents or to be filed as exhibits thereto have been described or filed as
required. Neither Parent or any of its

                                      -25-
<PAGE>   33
Subsidiaries nor, to the knowledge of Parent, any other party is in breach of or
default under any such contracts which are currently in effect, except for such
breaches and defaults which would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on Parent.

                  Section 2.15 ERISA. Each Parent Plan complies in all material
respects with the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), the Code and all other applicable laws and administrative or
governmental rules and regulations. No "reportable event" (within the meaning of
Section 4043 of ERISA) has occurred with respect to any Parent Plan for which
the 30-day notice requirement has not been waived (other than with respect to
the transactions contemplated by this Agreement), and no condition exists which
would subject Parent or any ERISA Affiliate (as hereinafter defined) to any fine
under Section 4071 of ERISA; except as disclosed in the Parent Letter, neither
Parent nor any of its ERISA Affiliates has withdrawn from any Parent Plan or
Parent Multiemployer Plan (as hereinafter defined) or has taken, or is currently
considering taking, any action to do so; and no action has been taken, or is
currently being considered, to terminate any Parent Plan subject to Title IV of
ERISA. No Parent Plan, nor any trust created thereunder, has incurred any
"accumulated funding deficiency" (as defined in Section 302 of ERISA), whether
or not waived. To the knowledge of Parent, there are no actions, suits or claims
pending or threatened (other than routine claims for benefits) with respect to
any Parent Plan which would reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect on Parent. Neither Parent nor any of
its ERISA Affiliates has incurred or would reasonably be expected to incur any
material liability under or pursuant to Title IV of ERISA. No prohibited
transactions described in Section 406 of ERISA or Section

                                      -26-
<PAGE>   34
4975 of the Code have occurred which would reasonably be expected to result in
material liability to Parent or its Subsidiaries. Except as set forth in the
Parent Letter, all Parent Plans that are intended to be qualified under Section
401(a) of the Code have received a favorable determination letter as to such
qualification from the Internal Revenue Service, and no event has occurred,
either by reason of any action or failure to act, which would cause the loss of
any such qualification. Parent is not aware of any reason why any Parent Plan is
not so qualified in operation. Neither Parent nor any of its ERISA Affiliates
has been notified by any Parent Multiemployer Plan that such Parent
Multiemployer Plan is currently in reorganization or insolvency under and within
the meaning of Section 4241 or 4245 of ERISA or that such Parent Multiemployer
Plan intends to terminate or has been terminated under Section 4041A of ERISA.
Parent and its Subsidiaries have complied with the health care continuation
requirements of Part 6 of Title I of ERISA. Except as set forth in the Parent
Letter, the execution and delivery of this Agreement does not, and the
consummation of the transactions contemplated hereby and compliance with the
provisions hereof will not, result in an increase in the amount of compensation
or benefits or accelerate the vesting or timing of payment of any compensation
or benefits payable by Parent or its Subsidiaries to or in respect of any
employee or other person. As used in this Agreement: (i) "Parent Plan" means a
"pension plan" (as defined in Section 3(2) of ERISA, other than a Parent
Multiemployer Plan) or a "welfare plan" (as defined in Section 3(1) of ERISA)
established or maintained by Parent or any of its ERISA Affiliates or to which
Parent or any of its ERISA Affiliates has contributed or otherwise may have any
liability; (ii) "Parent Multiemployer Plan" means a "multiemployer plan" (as
defined in Section 4001(a)(3) of ERISA) to which Parent or any of its ERISA
Affiliates is or has been obligated to contribute or otherwise may have any
liability; and (iii) with respect to any person, "ERISA Affiliate" means

                                      -27-
<PAGE>   35
any trade or business (whether or not incorporated) which is under common
control or would be considered a single employer with such person pursuant to
Section 414(b), (c), (m) or (o) of the Code and the regulations promulgated
thereunder or pursuant to Section 4001(b) of ERISA and the regulations
promulgated thereunder.

                  Section 2.16 Liabilities. Except as fully reflected or
reserved against in the consolidated financial statements included in the Parent
Annual Report to Stockholders for the fiscal year ended December 2, 1995, or
disclosed in the footnotes thereto, Parent and its Subsidiaries had no
liabilities (including, without limitation, Tax liabilities) at the date of such
consolidated financial statements, absolute or contingent, that would reasonably
be expected to have a Material Adverse Effect on Parent or not incurred in the
ordinary course of business. Except as so reflected, reserved or disclosed,
Parent and its Subsidiaries have no commitments which would reasonably be
expected to have a Material Adverse Effect on Parent.

                  Section 2.17 Intellectual Properties. All of the material

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company represents and warrants to Parent and Sub as
follows:

                  Section 3.1 Organization, Standing and Power. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Ohio and has

                                      -30-
<PAGE>   38
the requisite corporate power and authority to carry on its business as now
being conducted. Each Subsidiary of the Company is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction in
which it is incorporated and has the requisite corporate power and authority to
carry on its business as now being conducted. Except as disclosed in the Company
Letter (as hereinafter defined), the Company and each of its Subsidiaries are
duly qualified to do business, and are in good standing, in each jurisdiction
where the character of their properties owned or held under lease or the nature
of their activities makes such qualification necessary, except where the failure
to be so qualified would not reasonably be expected to have, individually or in
the aggregate, a Material Adverse Effect on the Company.

                  Section 3.2 Capital Structure. As of the date hereof, the
authorized capital stock of the Company consists of: 4,000,000 Company Common
Shares. On the date hereof, 2,908,828 Company Common Shares were issued and
outstanding, all of which were validly issued, are fully paid and nonassessable
and are free of preemptive rights. As of the date of this Agreement, except as
provided in the Company's Articles of Incorporation, as amended, except as set
forth in the Company Letter (as hereinafter defined), and except for stock
options issued prior to the date hereof covering not in excess of 360,813
Company Common Shares (collectively, the "Company Stock Options"), there are no
options, warrants, calls, rights or agreements to which the Company or any of
its Subsidiaries is a party or by which any of them is bound obligating the
Company or any of its Subsidiaries to issue, deliver or sell, or cause to be
issued, delivered or sold, additional shares of capital stock of the Company or
any such Subsidiary or obligating the Company or any such Subsidiary to grant,
extend or enter into any

                                      -31-
<PAGE>   39
such option, warrant, call, right or agreement. Each outstanding share of
capital stock of each Subsidiary of the Company is duly authorized, validly
issued, fully paid and nonassessable and, except as disclosed in the Company SEC
Documents or the Company Letter (as such term is hereinafter defined), each such
share is beneficially owned by the Company or another Subsidiary of the Company,
free and clear of all security interests, liens, claims, pledges, options,
rights of first refusal, agreements, limitations on voting rights, charges and
other encumbrances of any nature whatsoever. Exhibit 21 to the Company's Annual
Report on Form 10-K for the fiscal year ended June 30, 1995, as filed with the
SEC (the "Company Annual Report"), is a true, accurate and correct statement in
all material respects of all of the information required to be set forth therein
by the regulations of the SEC.

                  Section 3.3 Authority. The Board of Directors of the Company
has declared as advisable and fair to and in the best interests of the
shareholders of the Company the Merger and approved this Agreement, and the
Company has all requisite power and authority to enter into this Agreement and,
subject to approval of the Merger by the shareholders of the Company, to
consummate the transactions contemplated hereby. The execution and delivery of
this Agreement by the Company and the consummation by the Company of the
transactions contem plated hereby have been duly authorized by all necessary
corporate action on the part of the Company, subject, in the case of this
Agreement, to approval of the Merger by the shareholders of the Company. This
Agreement has been duly executed and delivered by the Company and (assuming the
valid authorization, execution and delivery thereof by Sub and Parent and the
validity and binding effect thereof on Sub and Parent) constitutes the valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms. The

                                      -32-

filing of the Proxy Statement with the SEC has been duly authorized by the
Company's Board of Directors.

                  Section 3.4 Consents and Approvals; No Violation. Except as
set forth in the letter dated and delivered to Parent on the date hereof (the
"Company Letter"), which relates to this Agreement and is designated therein as
being the Company Letter, the execution and delivery of this Agreement do not,
and the consummation of the transactions contemplated hereby and compliance with
the provisions hereof will not, result in any violation of, or default (with or
without notice or lapse of time, or both) under, or give rise to a right of
termination, cancellation or acceleration of any obligation or to the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of the
Company or any of its Subsidiaries under: (i) any provision of the Articles of
Incorporation or Regulations of the Company or the comparable charter or
organization documents or by-laws of any of its Subsidiaries as amended, (ii)
any loan or credit agreement, note, bond, mortgage, indenture, lease, agreement,
instrument, permit, concession, franchise or license applicable to the Company
or any of its Subsidiaries or (iii) any judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to the Company or any of its
Subsidiaries or any of their respective properties or assets, other than, in the
case of clauses (ii) and (iii), any such violations, defaults, rights, liens,
security interests, charges or encumbrances that, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company and would not materially impair the ability of the Company to
perform its obligations hereunder or prevent the consummation of any of the
transactions contemplated hereby. No filing or registration with, or
authorization, consent or approval of, any

                                      -33-
<PAGE>   41
Governmental Entity is required by or with respect to the Company or any of its
Subsidiaries in connection with the execution and delivery of this Agreement by

compliance, with the provisions of the HSR Act, the Securities Act and the
Exchange Act, (ii) for the filing of the Certificate of Merger with the
Secretary of State of the State of Ohio, (iii) for such consents, approvals,
orders, authorizations, 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 property or assets and (iv)
for such other consents, orders, authorizations, registrations, declarations and
filings the failure of which to obtain or make would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company and would not materially impair the ability of the Company to perform
its obligations hereunder or prevent the consummation of any of the transactions
contemplated hereby.

                  Section 3.5 Company SEC Documents and Financial Statements.
The Company has filed all required documents with the SEC since January 1, 1991
(the "Company SEC Documents"). As of their respective dates, the Company SEC
Documents complied in all material respects with the requirements of the
Securities Act or the Exchange Act, as the case may be, and none of the Company
SEC Documents contained any untrue statement of a material fact or omitted to
state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. The Company Letter includes the consolidated balance sheets of
the Company and its consolidated subsidiaries as of June 30, 1996 and 1995 and
the related consolidated statements of

                                      -34-

each of the fiscal years then ended, together with the appropriate notes to such
financial statements, accompanied by the report thereon of Arthur Andersen LLP,
independent public accountants (the "Audited Financial Statements"). The
consolidated financial statements of the Company included in the Company SEC
Documents and the Company Letter complied as to form in all material respects
with the applicable accounting requirements and the published rules and
regulations with respect thereto. The consolidated financial statements included
in the Company SEC Documents and the Audited Financial Statements have been
prepared in accordance with generally accepted accounting principles (except, in
the case of the unaudited statements, as permitted by Form 10-Q of the SEC)
applied on a consistent basis during the periods involved (except as may be
indicated therein or in the notes thereto) and fairly present in all material
respects the consolidated financial position of the Company and its consolidated
Subsidiaries as at the respective dates thereof and the consolidated results of
their operations and their consolidated cash flows for the respective periods
then ended (subject, in the case of the unaudited statements, to normal year-end
audit adjustments and to any other adjustments described therein). None of the
financial statements referred to in this Section 3.5 contains any material items
of special or nonrecurring income except as expressly specified therein. Since
June 30, 1996, the Company has not made any change in the accounting practices
or policies applied in the preparation of its financial statements.

                  Section 3.6 Registration Statement and Proxy Statement. None

at the time it becomes effective, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or

case of the Proxy Statement, at the time of the mailing of the Proxy Statement,
the time of the Company Stockholder Meeting 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. If at any time prior to the Effective Time any event with respect to
the Company, its directors and officers or any of its Subsidiaries shall occur
which is required to be described in the Proxy Statement or the Registration
Statement, such event shall be so described, and an appropriate amendment or
supplement shall be promptly filed with the SEC and, to the extent required by
law, disseminated to the shareholders of the Company. The Registration Statement
will comply (with respect to the Company) as to form in all material respects
with the provisions of the Securities Act, and the Proxy Statement will comply
(with respect to the Company) as to form in all material respects with the
provisions of the Exchange Act.

disclosed in the Company SEC Documents or the Company Letter, since June 30,
1996: (i) the Company and its Subsidiaries have not incurred any material

calamity (whether or not covered by insurance) that has had or that would
reasonably be expected to have a Material Adverse Effect on the Company; (iii)
there has been no material change in the indebtedness of the Company and its
Subsidiaries, no change in the outstanding shares of capital stock of the

by the Company on any class of its capital stock; (iv) there has been no event
causing a Material Adverse Effect on the Company, nor any development that
would, individually or in the aggregate, reasonably be expected to result in a
Material Adverse Effect on the Company; and except as set forth in the Company
Letter, during the period from June 30, 1996 through the date of this Agreement,
neither the Company nor any of its Subsidiaries has taken any action that, if
taken during the period from the date of this Agreement through the Effective
Time, would constitute a breach of Section 4.1(b).

                  Section 3.8 No Existing Violation, Default, Etc. Neither the
Company nor any of its Subsidiaries is in violation of (i) its charter or other
organization documents or by-laws, (ii) any applicable law, ordinance or
administrative or governmental rule or regulation or (iii) any order, decree or
judgment of any Governmental Entity having jurisdiction over the Company or any
of its Subsidiaries, except for any violations that, individually or in the
aggregate, would not reasonably be expected to have a Material Adverse Effect on
the Company. The properties, assets and operations of the Company and its
Subsidiaries are in compliance in all material respects with all applicable
Worker Safety Laws and Environmental Laws, except for any violations that,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the Company. With respect to such properties, assets
and operations,

                                      -37-
<PAGE>   45
including any previously owned, leased or operated properties, assets or
operations, there are no past, present or reasonably anticipated future events,
conditions, circumstances, activities, practices, incidents, actions or plans of
the Company or any of its Subsidiaries that may interfere with or prevent
compliance or continued compliance in all material respects with applicable

prevention as would not, individually or in the aggregate with any such other
interference or prevention, reasonably be expected to have a Material Adverse
Effect on the Company.

                  Except as may be set forth in the Company SEC Documents or the
Company Letter, prior to the date of this Agreement, no event of default or
event that, but for the giving of notice or lapse of time, or both, would
constitute an event of default exists or, upon the consummation by the Company
of the transactions contemplated by this Agreement, will exist under any loan or
credit agreement, note, bond, mortgage, indenture or guarantee of indebtedness
for borrowed money or any other material lease, agreement or instrument to which
the Company or any of its Subsidiaries is a party or by which the Company or any
such Subsidiary or any of their respective properties, assets or business is
bound.

                  Section 3.9 Licenses and Permits. The Company and its
Subsidiaries have received such certificates, permits, licenses, franchises,
consents, approvals, orders, authorizations and clearances from appropriate
Governmental Entities (the "Company Licenses") as are necessary to own or lease
and operate their respective properties and to conduct their respective
businesses substantially in the manner described in the Company SEC Documents
and as currently owned or leased and conducted, and all such Company Licenses
are valid and in full

                                      -38-
<PAGE>   46
force and effect, except for any such certificates, permits, licenses,
franchises, consents, approvals, orders, authorizations and clearances which the
failure to have or to be in full force and effect would not reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect on
the Company. The Company and its Subsidiaries are in compliance in all material
respects with their respective obligations under the Company Licenses, with only
such exceptions as, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect on the Company, and no event has
occurred that allows, or after notice or lapse of time, or both, would allow,
revocation or termination of any material Company License.

remedial action, under any Environmental Laws that would reasonably be expected
to have a Material Adverse Effect on the Company; and there are no pending,
reasonably anticipated or, to the knowledge of the Company, threatened actions,
suits or proceedings against or affecting the Company, any of its Subsidiaries
or any of their respective properties, assets or operations asserting any such
liability or seeking any such remedial action in connection with any
Environmental Laws that would reasonably be expected to have a Material Adverse
Effect on the Company.

practice with respect to Company Business Personnel, and there is no unfair
labor practice complaint pending against the Company or any or its Subsidiaries
with respect to Company Business Personnel. There is no labor strike, dispute,

"WARN Act") and has no liabilities pursuant to the WARN Act.

                  Section 3.14 Contracts. All of the material contracts of the
Company and its Subsidiaries are listed and described in the Company Letter or
if required to be described in the Company SEC Documents or to be filed as
exhibits thereto have been described or filed as required. For the purposes of
this Section 3.14, the term "material" means contracts required to be disclosed
by Item 601(10) of Regulation S-K promulgated by the SEC. Neither the Company or
any of its Subsidiaries nor, to the knowledge of the Company, any other party is
in breach of or default under any such contracts which are currently in effect,
except for such breaches and defaults which would not reasonably be expected to
have, individually or in the aggregate, a Material Adverse Effect on the
Company.

                  Section 3.15 ERISA. Each Company Plan complies in all material
respects with ERISA, the Code and all other applicable laws and administrative
or governmental rules and


                                      -42-
<PAGE>   50
regulations. No "reportable event" (within the meaning of Section 4043 of ERISA)
has occurred with respect to any Company Plan for which the 30-day notice
requirement has not been waived (other than with respect to the transactions
contemplated by this Agreement), and no condition exists which would subject the
Company or any ERISA Affiliate to any fine under Section 4071 of ERISA; except
as disclosed in the Company Letter neither the Company nor any of its ERISA
Affiliates has withdrawn from any Company Plan or Company Multiemployer Plan (as
hereinafter defined) or has taken, or is currently considering taking, any
action to do so; and no action has been taken, or is currently being considered,
to terminate any Company Plan subject to Title IV of ERISA. No Company Plan, nor
any trust created thereunder, has incurred any "accumulated funding deficiency"
(as defined in Section 302 of ERISA), whether or not waived. To the knowledge of
the Company, there are no actions, suits or claims pending or threatened (other
than routine claims for benefits) with respect to any Company Plan which would
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect on the Company. Neither the Company nor any of its ERISA
Affiliates has incurred or would reasonably be expected to incur any material
liability under or pursuant to Title IV of ERISA. No prohibited transactions
described in Section 406 of ERISA or Section 4975 of the Code have occurred
which would reasonably be expected to result in material liability to the
Company or its Subsidiaries. Except as set forth in the Company Letter, all
Company Plans that are intended to be qualified under Section 401(a) of the Code
have received a favorable determination letter as to such qualification from the
Internal Revenue Service, and no event has occurred, either by reason of any
action or failure to act, which would cause the loss of any such qualification.
Except as set forth in the Company Letter, the Company is not aware of any
reason why any Company Plan is not so qualified in operation. Neither the
Company nor any of its ERISA Affiliates has been


                                      -43-
<PAGE>   51
notified by any Company Multiemployer Plan that such Company Multiemployer Plan
is currently in reorganization or insolvency under and within the meaning of
Section 4241 or 4245 of ERISA or that such Company Multiemployer Plan intends to
terminate or has been terminated under Section 4041A of ERISA. The Company and
its Subsidiaries have complied with the health care continuation requirements of
Part 6 of Title I of ERISA. Except as set forth in the Company Letter, the
execution and delivery of this Agreement does not, and the consummation of the
transactions contemplated hereby and compliance with the provisions hereof will
not, result in an increase in the amount of compensation or benefits or
accelerate the vesting or timing of payment of any compensation or benefits
payable by the Company or its Subsidiaries to or in respect of any employee or
other person. As used in this Agreement: (i) "Company Plan" means a "pension
plan" (as defined in Section 3(2) of ERISA, other than a Company Multiemployer
Plan) or a "welfare plan" (as defined in Section 3(1) of ERISA) established or
maintained by the Company or any of its ERISA Affiliates or to which the Company

in the exercise of reasonable judgment (based on the advice of independent
financial advisors), to be more favorable to the Company and its shareholders
than the transactions contemplated hereby and for which any required financing
is committed or which, in the good faith and reasonable judgment of a majority
of such members, is reasonably capable of being financed by such person; and

Subsidiaries shall (i) knowingly take or fail to take any action which action or

promptly as practicable following the effectiveness of the Registration
Statement for the purpose of voting upon the Merger. The Company shall, through
its Board of Directors, recommend to its stockholders approval of such matters
and shall not withdraw such recommendation; provided, however, that such Board
of Directors shall not be required to make, and shall be entitled to withdraw,
such recommendation if such Board of Directors concludes in good faith on the

failure to withdraw, such recommendation would violate the fiduciary obligations
of such Board of Directors under applicable law. The respective Boards of
Directors of the Company, Parent and Sub shall not withdraw their respective
declarations that the Merger is advisable unless, in any such case, any such

Proxy Statement. The Company and Parent shall promptly prepare and file with the
SEC the Registration Statement, which will include the Proxy Statement. Each of

as practicable after such filing. Parent shall also take any action (other than
qualifying to do business in any jurisdiction in which it is now not so
qualified) required to be taken under any applicable state securities laws in
connection with the issuance of Parent Common Stock in connection with the
Merger and upon any exercise of the Substitute Options (as defined in Section 
5.8). The Company shall furnish all information concerning the Company and the
holders of Company Common Shares as may be reasonably requested by Parent in

such inspections as they may reasonably request of, the other's properties,

its officers and employees as may be reasonably requested; and, during such
period, Parent and the Company shall, and shall cause each of its respective
Subsidiaries to, furnish promptly to the other (i) a copy of each report,
schedule, registration statement and other document filed by it during such
period pursuant to the requirements of federal or state securities laws and (ii)

Effective Time, the Company shall cause to be prepared and delivered to Parent a
list (reasonably satisfactory to counsel for Parent) identifying all persons
who, at the time of the Company Stockholder Meeting, may be deemed to be an

Rule 145 under the Securities Act (the "Rule 145 Affiliates"). The Company shall
use its reasonable best efforts to cause each person who is identified as a Rule
145 Affiliate in such list to deliver to Parent on or prior to the Effective
Time a written agreement, in the form previously approved by the parties hereto,

statement or in compli ance with such Rule 145 or another exemption from the
registration requirements of the Securities Act and (ii) sell or in any other
way reduce such Rule 145 Affiliate's risk relative to any shares of Parent
Common Stock received in the Merger (within the meaning of Section 201.01 of the

results (including combined sales and net income) covering at least 30 days of
post-Merger operations have been published, except as permitted by Staff
Accounting Bulletin No. 76 issued by the SEC. After the Effective Time, Parent
shall satisfy the conditions set forth in Rule 144(c)(1)

promulgated by the SEC under the Securities Act for so long as any Rule 145
Affiliate is subject to the provisions of Rule 145(d).

reasonable best efforts to list on the NYSE, upon official notice of issuance,

accountants, actuaries and consultants, shall be paid by the party incurring

Parent upon demand for all out-of-pocket fees and expenses incurred or paid by
or on behalf of Parent and its Subsidiaries in connection with this Agreement
and the transactions contemplated hereby, including all fees and expenses of

shall enter into a definitive agreement with respect to any Takeover Proposal,
or if any Takeover Proposal shall have been completed or the Board of Directors
of the Company shall have recommended to the shareholders of the Company any
Takeover Proposal or adopted a resolution to do so, then, upon the earliest of
such occurrences, the Company shall immediately pay to Parent an amount in cash
equal to $1,000,000, less any amount paid to Parent pursuant to the immediately
preceding sentence; provided that no amount shall be payable to Parent pursuant
to this sentence in the event that the Company would have had the right to

                  (c) Notwithstanding any provision in this Agreement to the
contrary, if this Agreement shall be terminated by Parent pursuant to Section 
7.1(b)(ii) or by the Company pursuant to Section 7.1(c)(ii) and, in either such
case, within one year after the date of such termination, any of the occurrences
described in the second sentence of Section 5.7(b) shall have occurred, the

<PAGE>   70
cash amount to Parent only upon the occurrence of the events set forth in
clauses (i) and (ii) thereof unless the Company shall have failed to timely
provide such written notice to, or cooperated fully with, Parent as required by
such clause (i); and (ii) pursuant to Section 7.1(g), the Company shall not be
required to pay such cash amount to Parent if, (A) at the time that the Board
of Directors of the Company took such action described in Section 7.1(g), the   
Company would have been entitled to terminate this Agreement pursuant to
Section  7.1(i) (assuming, for the purpose of this clause (A) that the

within ten business days preceding the date the Board of Directors of the
Company took such action); or (B) the Board of Directors of the Company shall
have taken the action or actions specified by Section 7.1(g) in connection with

purchase plan" within the meaning of Section 423 of


                                      -63-
<PAGE>   71
the Code) of the Company in effect on the date hereof (the "Company Stock
Plans") shall become and represent an option to purchase the number of shares of
Parent Common Stock (a "Substitute Option"), increased to the nearest whole
share, determined by multiplying (i) the number of Company Common Shares subject
to such Company Stock Option immediately prior to the Effective Time by (ii) the
Conversion Number, at an exercise price per share of Parent Common Stock
(increased to the nearest whole cent) equal to the exercise price per Company
Common Share immediately prior to the Effective Time divided by the Conversion
Number. After the Effective Time, except as provided above in this Section 5.8,
each Substitute Option shall be exercisable upon the same terms and conditions
as were applicable to the related Company Stock Option immediately prior to the
Effective Time; provided, that any conditions to the exercise of the Company
Stock Options which are expressed in terms of the market price of the Company
Common Stock shall be adjusted by dividing such price by the Conversion Number.
This Section 5.8 shall be subject to any contrary provision contained in the
applicable Company Stock Plan or in the option agreement with respect to any
Company Stock Option outstanding thereunder, but the Company shall use its

<PAGE>   73
                  (c) Each party hereto shall use its reasonable best efforts
not to take any action, or to enter into any transaction, which would cause any
of its representations or warranties contained in this Agreement to be untrue or
to result in a breach of any of its covenants in this Agreement.

                  (d) Notwithstanding any provision in this Agreement to the
contrary: (i) neither Parent nor the Company shall be obligated to use its
reasonable best efforts or to take any action pursuant to this Section 5.9 if
the Board of Directors of Parent or the Company, as the case may be, shall
conclude in good faith on the basis of the written advice of its outside counsel
that such action would violate the fiduciary obligations of such Board of
Directors under applicable law; and (ii) in connection with any filing or
submission required or action to be taken by either Parent or the Company to
effect the Merger and to consummate the other transactions contemplated hereby,

other, except as may be required by applicable law or by existing obligations

Subsidiaries' real properties, and any penalties or interest with respect
thereto, payable in connection with the consummation of the Merger. The Company
shall cooperate with Parent in the filing of any returns with respect to the
Gains Taxes, including supplying in a timely manner a complete list of all real

with respect to such properties that is reasonably necessary to complete such
returns. The portion of the consideration allocable to the real properties of
the Company and its Subsidiaries shall be determined by Parent in its reasonable
discretion. The shareholders of the Company shall be deemed to have agreed to be

preparation of any return with respect to the Gains Taxes.

                  Section 5.12 Takeover Statutes. If any Takeover Statute shall
become applicable to the transactions contemplated hereby, Parent and the
Company and their respective Boards of Directors shall use their reasonable best
efforts to grant such approvals and to take such other actions as are necessary

omissions occurring at or prior to the Effective Time, to the same extent such
persons are currently indemnified by the Company pursuant to the Company's
Amended Articles of Incorporation and Amended and Restated Code of Regulations.

                  Section 5.14 Notification of Certain Matters. Parent shall
give prompt notice to the Company, and the Company shall give prompt notice to

<PAGE>   79
                  (b) Tax Opinion. The Company shall have received an opinion of
Graydon, Head & Ritchey, in form and substance reasonably satisfactory to the
Company, dated the Effective Time, substantially to the effect that, on the
basis of facts, representations and assumptions set forth in such opinion which
are consistent with the state of facts existing as of the Effective Time, for
federal income tax purposes:

                  (i) The Merger will constitute a "reorganization" within the
         meaning of Section 368(a) of the Code, and the Company, Sub and Parent
         will each be a party to such reorganization within the meaning of
         Section 368(b) of the Code;

             (ii) No gain or loss will be recognized by the Company as a result
         of the Merger;

            (iii) No gain or loss will be recognized by the non-dissenting
         shareholders of the Company upon the conversion of their Company Common
         Shares into shares of Parent Common Stock in accordance with the
         Merger, except with respect to cash, if any, received in lieu of
         fractional shares of Parent Common Stock;

             (iv) The aggregate tax basis of the shares of Parent Common Stock
         received by a shareholder in exchange for Company Common Shares in
         accordance with the Merger (including fractional shares of Parent
         Common Stock for which cash is received) will be the same as the
         aggregate tax basis of such Company Common Shares;


                                      -72-
<PAGE>   80
              (v) The holding period for shares of Parent Common Stock received
         by a shareholder in exchange for Company Common Shares in accordance
         with the Merger will include the period that such Company Common Shares
         were held by the shareholder, provided such Company Common Shares were
         held as capital assets by such shareholder at the Effective Time; and

             (vi) A shareholder of the Company who receives cash in lieu of a
         fractional share of Parent Common stock will recognize gain or loss
         equal to the difference, if any, between such shareholder's basis in
         such fractional share and the amount of cash received.

In rendering such opinion, Graydon, Head & Ritchey may receive and rely upon
representations contained in a certificate of the Company substantially in the
form attached to the Company Letter (the "Company Tax Certificate"), a
certificate of Parent substantially in the form attached to the Parent Letter
(the "Parent Tax Certificate") and other appropriate certificates of the
Company, Parent and others, and may condition such opinion on the receipt from
each shareholder of the Company holding a substantial amount of the Company
Common Shares (a "Major Shareholder") of a certificate substantially in the form
attached to the Company Letter (the "Shareholder Certificate").

                  (c) Opinion of Sidley & Austin. The Company shall have

         the Company and its validity and binding effect upon the Company)
         constitutes the legal, valid and binding obligation of Parent and Sub
         enforceable against Parent and Sub in accordance with its terms, except
         to the extent enforceability may be limited by bankruptcy, insolvency,
         reorganization, moratorium, fraudulent transfer or other similar laws
         of general applicability relating to or affecting the enforcement of
         creditors' rights and by the effect of general principles of equity
         (regardless of whether enforceability is considered in a proceeding in
         equity or at law);

            (iii) The execution and performance by Parent and Sub of this
         Agreement will not violate the Restated Certificate of Incorporation or
         By-laws of Parent or the Articles of Incorporation or Regulations of
         Sub;

<PAGE>   82
             (iv) To the knowledge of such counsel, the execution and
         performance by Parent and Sub of this Agreement will not violate,
         result in a breach of or constitute a default under any material
         indenture, mortgage, evidence of indebtedness, lease, agreement,
         instrument, law, rule, regulation, judgment, order or decree to which
         Parent or any of its Subsidiaries is a party or by which any of them or

              (v) To the knowledge of such counsel, no consent, approval,
         authorization or order of any court or other Governmental Entity which
         has not been obtained is required on behalf of Parent or any of its
         Subsidiaries for the consummation of the transactions contemplated by
         this Agreement;

             (vi) To the knowledge of such counsel, there are no actions, suits

         contemplated by this Agreement;

            (vii) (A) At the time the Registration Statement became effective,

         financial data, statistical data and supporting schedules included

         which such counsel need express no opinion) complied as to form in all
         material respects with the requirements of the Securities Act; and (B)

         preparation of the Registration Statement and the Proxy Statement, such
         counsel has considered the information set forth therein in light of
         the matters required to be set forth therein, and has participated in
         conferences with officers and representatives of the Company and
         Parent, including their respective counsel and independent public
         accountants, during the course of which the contents of the
         Registration Statement and the Proxy Statement and related matters were
         discussed; such counsel has not independently checked the accuracy or
         completeness of, or otherwise verified, and accordingly is not passing
         upon, and does not assume responsibility for, the accuracy,
         completeness or fairness of the statements contained in the
         Registration Statement or the Proxy Statement; such counsel has relied
         as to materiality, to a large extent, upon the judgment of officers and
         representatives of the Company and Parent; however, as a result of such
         consideration and participation, nothing has come to such counsel's
         attention which causes such counsel to believe that the Registration
         Statement (other than the financial statements, financial data,
         statistical data and supporting schedules included therein, and
         information relating to or supplied by the Company, as to which such
         counsel need express no belief), at the time it became effective,
         contained any untrue statement of a material fact or omitted to state
         any material fact required to be stated therein or necessary to make
         the statements therein not misleading or that the Proxy Statement
         (other than the financial statements, financial data, statistical data
         and supporting schedules included therein, and information relating to
         or supplied by the Company, as to which such counsel need express no
         belief), at the time the Registration Statement became effective and at
         the time of the Company Stockholder Meeting, included any untrue
         statement of a material fact or omitted to state any material fact
         necessary in order


                                      -76-
<PAGE>   84
         to make the statements therein, in the light of the circumstances under
         which they were made, not misleading; and

           (viii) The shares of Parent Common Stock being issued at the
         Effective Time pursuant to this Agreement have been duly authorized and
         validly issued and are fully paid and nonassessable.

                  In rendering such opinion, Sidley & Austin may rely as to
matters of fact upon the representations contained herein and in certificates of
officers of Parent and its Subsidiaries delivered to such counsel and
certificates of public officials. Such opinion may state that it is limited to
the General Corporation Law of the State of Delaware, the laws of the State of
Illinois and the federal laws of the United States of America and that, insofar
as the laws of the State of Ohio are applicable, such counsel has relied upon
the opinion of Taft, Stettinius & Hollister delivered to the Company pursuant to
Section 6.2(d).

                  (d) Opinion of Taft, Stettinius & Hollister. The Company shall
have received an opinion of Taft, Stettinius & Hollister, dated the Effective
Time, substantially to the effect that: (i) Sub is a corporation duly organized,
validly existing and in good standing under the laws of the State of Ohio; (ii)
Sub has full corporate power and authority to execute, deliver and perform this
Agreement; (iii) this Agreement has been duly authorized, executed and delivered
by Sub and (assuming its due and valid authorization, execution and delivery by
Parent and the Company and its validity and binding effect upon the Company)
constitutes the legal, valid and binding obligation of Parent and Sub
enforceable against Parent and Sub in accordance with its


                                      -77-
<PAGE>   85
terms, except to the extent enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or other similar
laws of general applicability relating to or affecting the enforcement of
creditors' rights and by the effect of general principles of equity (regardless
of whether enforceability is considered in a proceeding in equity or at law);
and (iv) the Merger has been duly consummated and become effective in accordance
with the OGCL. In rendering such opinion, Taft, Stettinius & Hollister may rely
as to matters of fact upon the representations contained herein and in
certificates of officers of Parent and its Subsidiaries delivered to such
counsel and certificates of public officials. Such opinion may state that it is
limited to the laws of the State of Ohio.

                  (e) Consents Under Agreements. Parent shall have obtained the
consent or approval of each person (other than the Governmental Entities
referred to in Section 6.1(c)) whose consent or approval shall be required in
connection with the transactions contemplated hereby under any indenture,
mortgage, evidence of indebtedness, lease or other agreement or instrument,
except where the failure to obtain the same would not reasonably be expected, in
the good faith opinion of the Company, individually or in the aggregate, to have
a Material Adverse Effect on Parent or upon the consummation of the transactions
contemplated hereby.

                  (f) Non-Compete Agreements. The Agreement, dated as of
September 23, 1996, by and among Parent, the Company and Durwood G. Rorie, Jr.
("Rorie"), and the Agreement, dated as of September 23, 1996, by and among

<PAGE>   86
                  (g) Material Adverse Change. Since the date of this Agreement,
there shall have been no Material Adverse Change with respect to Parent; and the
Company shall have received a certificate signed on behalf of Parent by its
Chief Executive Officer and its Chief Financial Officer to such effect.

                  Section 6.3 Conditions to Obligations of Parent and Sub to
Effect the Merger. The obligation of Parent and Sub to effect the Merger shall
be subject to the fulfillment at or prior to the Effective Time of the following
additional conditions:

                  (a) Performance of Obligations; Representations and
Warranties. The Company shall have performed in all material respects each of
its agreements contained in this Agreement required to be performed at or prior
to the Effective Time, each of the representations and warranties of the Company
contained in this Agreement that is qualified by materiality shall be true and
correct at and as of the Effective Time as if made at and as of the Effective
Time and each of such representations and warranties that is not so qualified
shall be true and correct in all material respects at and as of the Effective
Time as if made at and as of the Effective Time, in each case except as
contemplated or permitted by this Agreement; and Parent shall have received a
certificate signed on behalf of the Company by its Chief Executive Officer and
its Chief Financial Officer to such effect.

                  (b) Tax Opinion. Parent shall have received an opinion of
Sidley & Austin, in form and substance reasonably satisfactory to Parent, dated
the Effective Time, substantially to the effect that, on the basis of facts,
representations and assumptions set forth in such opinion


                                      -79-
<PAGE>   87
which are consistent with the state of facts existing as of the Effective Time,
for federal income tax purposes:

                  (i) The Merger will constitute a "reorganization" within the
         meaning of Section 368(a) of the Code, and the Company, Sub and Parent
         will each be a party to such reorganization within the meaning of
         Section 368(b) of the Code;

                  (ii) No gain or loss will be recognized by Parent or the
         Company as a result of the Merger;

                  (iii) No gain or loss will be recognized by the non-dissenting
         shareholders of the Company upon the conversion of their Company Common
         Shares into shares of Parent Common Stock in accordance with the
         Merger, except with respect to cash, if any, received in lieu of
         fractional shares of Parent Common Stock;

                  (iv) The aggregate tax basis of the shares of Parent Common
         Stock received by a shareholder in exchange for Company Common Shares
         in accordance with the Merger (including fractional shares of Parent
         Common Stock for which cash is received) will be the same as the
         aggregate tax basis of such Company Common Shares;

                  (v) The holding period for shares of Parent Common Stock
         received by a shareholder in exchange for Company Common Shares in
         accordance with the Merger will include the period that such Company
         Common Shares were held by the shareholder, provided


                                      -80-
<PAGE>   88
         such Company Common Shares were held as capital assets by such
         shareholder at the Effective Time; and

                  (vi) A shareholder of the Company who receives cash in lieu of
         a fractional share of Parent Common Stock will recognize gain or loss
         equal to the difference, if any, between such shareholder's basis in
         such fractional share and the amount of cash received.

In rendering such opinion, Sidley & Austin may receive and rely upon
representations contained in a certificate of the Company substantially in the
form of the Company Tax Certificate, a certificate of Parent substantially in
the form of the Parent Tax Certificate and other appropriate certificates of the
Company, Parent and others, and may condition such opinion on the receipt from
each Major Shareholder of a Shareholder Certificate.

                  (c) Opinion of Jack W. Painter, Esq., Parent shall have
received an opinion from Jack W. Painter, Esq., dated the Effective Time,
substantially to the effect that:

                  (i) The Company is a corporation in good standing under the
         laws of the State of Ohio, and the authorized shares of the capital
         stock of the Company are as stated in the first sentence of Section 
         3.2;

             (ii) The Company has full corporate power and authority to execute,
         deliver and perform this Agreement, and this Agreement has been duly
         authorized, executed and delivered by the Company and (assuming its due
         and valid authorization, execution and


                                      -81-
<PAGE>   89
         delivery by Parent and Sub and its validity and binding effect upon
         Parent and Sub) constitutes the legal, valid and binding obligation of
         the Company enforceable against the Company in accordance with its
         terms, except to the extent enforceability may be limited by
         bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer
         or other similar laws of general applicability relating to or affecting
         the enforcement of creditors' rights and by the effect of general
         principles of equity (regardless of whether enforceability is
         considered in a proceeding in equity or at law);

            (iii) The execution and performance by the Company of this Agreement
         will not violate the Articles of Incorporation or Regulations of the
         Company or the charter or organization documents or by-laws of any of
         its Subsidiaries;

             (iv) To the knowledge of such counsel, the execution and
         performance by the Company of this Agreement will not violate, result
         in a breach of or constitute a default under any material indenture,
         mortgage, evidence of indebtedness, lease, agreement, instrument, law,
         rule, regulation, judgment, order or decree to which the Company or any
         of its Subsidiaries is a party or by which any of them or any of their
         respective properties or assets are bound;

              (v) To the knowledge of such counsel, no consent, approval,
         authorization or order of any court or other Governmental Entity which
         has not been obtained is required on behalf of the Company or any of
         its Subsidiaries for consummation of the transactions contemplated by
         this Agreement;


                                      -82-
<PAGE>   90
             (vi) To the knowledge of such counsel, there are no actions, suits
         or proceedings, pending or overtly threatened, against or affecting the
         Company or any of its Subsidiaries, at law or in equity or before or by
         any court or other Governmental Entity or before any arbitrator, which
         seek to restrain, prohibit or invalidate any of the transactions
         contemplated by this Agreement; and

            (vii) (A) At the time the Registration Statement became effective,
         the Registration Statement (other than the financial statements,
         financial data, statistical data and supporting schedules included
         therein, and information relating to or supplied by Parent, as to which
         such counsel need express no opinion) complied as to form in all
         material respects with the requirements of the Securities Act; and (B)
         in the course of the preparation of the Registration Statement and the
         Proxy Statement, such counsel has considered the information set forth
         therein in light of the matters required to be set forth therein, and
         has participated in conferences with officers and representatives of
         the Company and Parent, including their respective counsel and
         independent public accountants, during the course of which the contents
         of the Registration Statement and the Proxy Statement and related
         matters were discussed; such counsel has not independently checked the
         accuracy or completeness of, or otherwise verified, and accordingly is
         not passing upon, and does not assume responsibility for, the accuracy,
         completeness or fairness of the statements contained in the
         Registration Statement or the Proxy Statement; such counsel has relied
         as to materiality, to a large extent, upon the judgment of officers and
         representatives of the Company and Parent; however, as a result of such
         consideration and participation, nothing has come to such counsel's
         attention


                                      -83-
<PAGE>   91
         which causes such counsel to believe that the Registration Statement
         (other than the financial statements, financial data, statistical data
         and supporting schedules included therein, and information relating to
         or supplied by Parent, as to which such counsel need express no
         belief), at the time it became effective, contained any untrue
         statement of a material fact or omitted to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading or that the Proxy Statement (other than the
         financial statements, financial data, statistical data and supporting
         schedules included therein, and information relating to or supplied by
         Parent, as to which such counsel need express no belief), at the time
         the Registration Statement became effective and at the time of the
         Company Stockholder Meeting, included any untrue statement of a
         material fact or omitted to state any material fact necessary in order
         to make the statements therein, in the light of the circumstances under
         which they were made, not misleading.

                  In rendering such opinion, such counsel may rely as to matters
of fact upon the representations contained herein and on certificates of
officers of the Company delivered to such counsel and certificates of public
officials. Such opinion may state that it is limited to the laws of the State of
Ohio, the General Corporation law of the State of Delaware and the federal laws
of the United States of America.

                  (d) Opinion of Graydon, Head & Ritchey. Parent shall have
received an opinion from Graydon, Head & Ritchey, dated the Effective Time,
substantially to the effect that (i) the Company is a corporation duly organized
and validly existing under the laws of the State of Ohio; and (ii) all
outstanding Company Common Shares have been duly and validly authorized


                                      -84-

and issued, are fully paid and nonassessable and have not been issued in
violation of any preemptive right of shareholders.

                  In rendering such opinion, such counsel may rely as to matters
of fact upon the representations contained herein and in certificates of
officers of the Company delivered to such counsel. Such opinion may state that
it is limited to the laws of the State of Ohio.

                  (e) Consents Under Agreements. The Company shall have obtained
the consent or approval of each person (other than the Governmental Entities
referred to in Section 6.1(c)) whose consent or approval shall be required in
connection with the transactions contemplated hereby under any indenture,
mortgage, evidence of indebtedness, lease or other agreement or instrument,
except where the failure to obtain the same would not reasonably be expected, in
the good faith opinion of Parent, individually or in the aggregate, to have a
Material Adverse Effect on the Company or Parent or upon the consummation of the
transactions contemplated hereby.

                  (f) Affiliate Agreements. Parent shall have received the
written agreements from the Rule 145 Affiliates of the Company described in

pending, or threatened, any suit, action or proceeding before any Governmental
Entity as a result of this Agreement or any of the transactions contemplated
hereby which, if such Governmental Entity were to prevail, would reasonably be
expected, in the good faith opinion of Parent, to have a Material Adverse Effect
on Parent or the Company (as the Surviving Corporation).

<PAGE>   93
                  (h) Accounting. Parent shall have received an opinion of
Coopers & Lybrand LLP, in form and substance reasonably satisfactory to Parent,
that the Merger will qualify as a pooling of interests under generally accepted
accounting principles; and based on such opinion and such other advice as Parent
may deem relevant, Parent shall have no reasonable basis for believing that the
Merger may not be accounted for as a pooling of interests in accordance with
generally accepted accounting principles.

                  (i) Non-Compete Agreements. The Non-Compete Agreements shall
become effective at the Effective Time.

<PAGE>   95
                  (c) by the Company, as authorized by its Board of Directors,

         respect with any of its respective covenants or agreements contained in
         this Agreement required to be complied with prior to the date of such
         termination, which failure to comply has not been cured within five

         (ii) any court or other Governmental Entity having jurisdiction over a
         party hereto shall have issued an order, decree or ruling or taken any

         other action permanently enjoining, restraining or otherwise

         order, decree, ruling or other action shall have become final and
         nonappealable;

                  (f) by either Parent or the Company, as authorized by its
         Board of Directors, if the Board of Directors of the Company shall
         determine that a Takeover Proposal constitutes a Superior Proposal;
         provided, however, that the Company may not terminate this Agreement
         pursuant to this clause (f) unless (i) 15 days shall have elapsed after
         delivery to Parent of a written notice of such determination by such
         Board of Directors and during such 15-day period the Company shall have
         fully cooperated with Parent, including, without limitation, informing
         Parent of the terms and conditions of such Takeover Proposal and the
         identity of the person or group making such Takeover Proposal, with the
         intent of enabling Parent to agree to a modification of the terms and
         conditions of this Agreement so that the transactions contemplated
         hereby may be effected, and (ii) at the end of such 15-day period such
         Board of Directors shall continue reasonably to believe that such
         Takeover Proposal constitutes a Superior Proposal and simultaneously

         only if, prior to such termination by Parent, the Board of Directors of
         the Company has not rejected such Takeover Proposal and has not
         terminated all discussions and negotiations pertaining to such


                                      -89-
<PAGE>   97
         Takeover Proposal; provided, further that the immediately preceding
         proviso shall apply only to the first Takeover Proposal determined by
         the Board of Directors of the Company to be a Superior Proposal; upon,
         and at any time after, any subsequent determination by the Board of
         Directors of the Company that any Takeover Proposal is a Superior
         Proposal, Parent shall have the right to terminate this Agreement
         pursuant to this clause (f);

                  (g) by Parent, as authorized by its Board of Directors, if the
         Board of Directors of the Company shall not have recommended the Merger
         to the Company's shareholders, or shall have resolved not to make such
         recommendation, or shall have modified or rescinded its recommendation
         of the Merger to the Company's shareholders as being advisable and fair
         to and in the best interests of the Company and its shareholders, or
         shall have modified or rescinded its approval of this Agreement, or
         shall have resolved to do any of the foregoing;

                  (h) by Parent, as authorized by its Board of Directors, if any
         Takeover Proposal (other than the Merger) involving the Company shall
         result in the acquisition by any person, entity or group (other than
         the Parent or any of its Subsidiaries) of 20% or more of the equity of,
         or 20% or more of the assets of, the Company or any of its Significant
         Subsidiaries; or

                  (i) by the Company, as authorized by its Board of Directors,
         in the event that on any date (the "Calculation Date") occurring within
         ten business days preceding the

         Closing, the per share closing price of Parent Common Stock on the NYSE
         (as shown in The Wall Street Journal, New York Stock Exchange Composite
         Transactions) is less than the dollar amount calculated by multiplying
         the Index Adjusted Price by 85%. The "Index Adjusted Price" is equal to
         the product obtained by multiplying (A) 21-1/2 by (B) the decimal
         determined by dividing the S&P 500 Index on the Calculation Date by the
         S&P 500 Index on the date of this Agreement (provided that in no event
         shall such decimal exceed 100%).

                  The right of Parent or the Company to terminate this Agreement
pursuant to this Section 7.1 shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of such party, whether
prior to or after the execution of this Agreement.

                  Section 7.2 Effect of Termination. In the event of the
termination of this Agreement by either Parent or the Company as provided in
Section 7.1, this Agreement shall forthwith become void without any liability
hereunder on the part of the Company, Parent, Sub or their respective directors
or officers, except for the last sentence of Section 5.4 and the entirety of
Section 5.7, which shall survive any such termination; provided, however, that
nothing contained in this Section 7.2 shall relieve any party hereto from any
liability for any breach of this Agreement.

                  Section 7.3 Amendment. This Agreement may be amended by the
parties hereto, by or pursuant to action taken by their respective Boards of
Directors, at any time before or after approval by the shareholders of the
Company of the matters presented to them in connection with


                                      -91-
<PAGE>   99
the Merger; provided, however, that after any such approval, no amendment shall
be made if applicable law would require further approval by such shareholders,
unless such further approval shall be obtained. This Agreement shall not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto.

                  Section 7.4 Waiver. At any time prior to the Effective Time,
the parties hereto may (i) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
instrument delivered pursuant hereto and (iii) waive compliance with any of the
agreements or conditions contained herein which may legally be waived; provided,
however, that after approval by the shareholders of the Company of the matters
presented to them in connection with the Merger, no waiver shall be made if
applicable law would require further approval by such shareholders, unless such
further approval shall be obtained. Any agreement on the part of any party
hereto to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party.

         WHEREAS, the Board of Directors of the Company has, prior to the

by the Stockholder:

         (a)  in favor of the Merger and the adoption of the Merger Agreement;

<PAGE>   2
                  (i) any extraordinary corporate transaction, such as a merger,

         business; or

                  (vi) any other action that is intended, or that could
         reasonably be expected, to impede, interfere with, delay, postpone or
         discourage, or adversely affect the contemplated economic benefits to
         Parent of the Merger and the actions or transactions contemplated by
         the Merger Agreement or this Agreement.

The Stockholder further agrees that the Stockholder will not enter into any
agreement or understanding with any person or entity prior to the termination of
this Agreement that is in any manner inconsistent with the provisions of this
Section 1.1.

                                    ARTICLE 2
                         REPRESENTATIONS AND WARRANTIEs

         Section 2.1 Representations and Warranties. The Stockholder hereby
represents and warrants to Parent as follows:

         (a) Ownership of Shares. The Stockholder is the record and beneficial
owner of the number of shares of Common Stock, without par value, of the Company
("Common Stock"), as set forth on Schedule A hereto (the "Existing Shares" and,
together with any shares of Common Stock acquired by the Stockholder hereafter
and prior to the termination of this Agreement, whether upon exercise of
options, conversion of convertible securities, purchase, exchange or otherwise,
the "Shares"). On the date hereof, the Existing Shares constitute all of the
shares of Common Stock owned of record or beneficially by the Stockholder.
Except as described on Schedule A attached hereto, the Stockholder has sole
voting power and sole power of disposition, sole power to demand an appraisal of
any Existing Shares entitled to appraisal pursuant to Section 1701.85 of the
Ohio General Corporation Law and sole power to engage in the actions set forth
herein, including those set forth in Article 3 hereof, in each case with respect
to all of the Existing Shares, with no restrictions on such rights except
pursuant to the terms of this Agreement.

                                      - 2 -
<PAGE>   3
         (b) Power; Binding Agreement. The Stockholder has the legal capacity,
power and authority to enter into and perform all of the Stockholder's
obligations under this Agreement. The execution, delivery and performance of
this Agreement by the Stockholder will not violate any other agreement to which
the Stockholder is a party or by which the Stockholder or any of the
Stockholder's properties or assets are or may be bound, including, without
limitation, any trust agreement, voting agreement, irrevocable proxy,
stockholders agreement or voting trust. This Agreement has been duly and validly
executed and delivered by the Stockholder and constitutes a valid and binding
agreement of the Stockholder, enforceable against the Stockholder in accordance
with its terms. There is no beneficiary, or holder of a voting trust certificate
or other interest, of any trust of which the Stockholder is a trustee whose
consent is required for the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby with respect to any
Existing Shares. If the Shares constitute community property, this Agreement has
been duly authorized, executed and delivered by, and constitutes a valid and
binding agreement of, each person having community property rights in the
Shares, enforceable against such person in accordance with its terms.

         (c) No Conflicts. Except pursuant to the Securities Exchange Act of
1934, as amended, no filing with, and no permit, authorization, consent or
approval of, any state or federal public body or authority or any other person
(or entity) is necessary for the execution of this Agreement by the Stockholder
and the performance by the Stockholder of the actions contemplated hereby.
Neither the execution and delivery of this Agreement by the Stockholder nor the
consummation by the Stockholder of the transactions contemplated hereby nor
compliance by the Stockholder with any of the provisions hereof will (i) result
in a violation or breach of, or constitute (with or without notice or lapse of
time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the
Stockholder or any of the Stockholder's properties or assets are or may be bound
or (ii) violate any order, writ, injunction, decree, judgment, statute, rule or
regulation applicable to the Stockholder or any of the Stockholder's properties
or assets.

         (d) No Adverse Claims. The Shares and the certificates representing
such Shares are now and at all times during the term of this Agreement will be
held by the Stockholder, or by a nominee or custodian for the benefit of the
Stockholder, free and clear of all liens, claims, security interests, proxies,
voting trusts or agreements, understandings or arrangements or any other
encumbrances whatsoever, except for any such encumbrances or proxies arising
under this Agreement.

         (e) No Brokers. No broker, investment banker, financial advisor or
other person is entitled to receive from the Company or any subsidiary any
broker's, finder's, financial advisor's or other similar fee or commission in
connection with the transactions contemplated hereby based on arrangements made
by or on behalf of the Stockholder.

<PAGE>   4
         (f) Material Reliance. The Stockholder understands and acknowledges
that Parent is entering into, and causing Sub to enter into, the Merger
Agreement in material reliance upon the Stockholder's execution and delivery of
this Agreement.

         (g) No Intention to Dispose. The Stockholder has no plan or intention
to, directly or indirectly, sell, exchange, or otherwise dispose of, reduce the
risk of loss by short sale or otherwise, or enter into any contract or other
arrangement with respect to, or consent to, the sale, exchange or other
disposition of any interest in any shares of Parent Common Stock (as defined in
the Merger Agreement) received pursuant to the Merger. The Stockholder
acknowledges that the Stockholder is giving this representation to enable
Graydon, Head & Ritchey and Sidley and Austin to opine that the Merger
constitutes a reorganization within the meaning of Section 368(a) of the Code
and further recognizes that significant adverse tax consequences might result if
such representation is not true. The Stockholder understands and agrees that, in
connection with the Merger, the Stockholder will give written notice to the
Company and Parent in the event that, at the Effective Time of the Merger (as

contemplated by the Merger Agreement.

         (ii) The Stockholder will not, and will not permit any of the
Stockholder's representatives or agents to, directly or indirectly, (A) solicit,
initiate or (excluding any action referred to in clauses (B) and (C) of this
sentence) encourage or take any action to facilitate the making of, any offer or
proposal that constitutes or that is reasonably likely to lead to any Takeover
Proposal, (B) participate in any discussions (other than as necessary to clarify
the terms and conditions of any unsolicited offer, including any financing or
other contingencies and other relevant facts with respect thereto) or
negotiations regarding any Takeover Proposal (other than with the Stockholder's
legal counsel, other Signatory Stockholders or officers or directors of the

                                      - 4 -

Company) or (C) furnish to any person (other than Parent or its representatives)
any nonpublic information or nonpublic data regarding the Company. The
Stockholder will notify Parent or officers or directors of the Company orally
and in writing of any such inquiries, offers or proposals to the Stockholder

any event within 24 hours after receipt thereof.

         (b) Restriction on Transfer; Proxies and Non-Interference; Restriction
on Withdrawal. The Stockholder shall not, directly or indirectly:

                  (i) except pursuant to the terms of the Merger Agreement and
         as set forth on Exhibit A, offer for sale, sell, transfer, tender,
         pledge, encumber, assign or otherwise dispose of (or in any other way
         reduce the Stockholder's risk of ownership in), or enter into any
         contract, option or other arrangement or understanding with respect to
         or consent to the offer for sale, sale, transfer, tender, pledge,
         encumbrance, assignment or other disposition of (or in any other way
         reduce the Stockholder's risk of ownership in), any or all of the
         Shares or any other equity securities of the Company or any interest
         therein;

                  (ii) except as contemplated by this Agreement, grant any
         proxies or powers of attorney, deposit any Shares into any voting trust
         or enter into any voting agreement with respect to any Shares; or

                  (iii) take any action that would make any representation or
         warranty of the Stockholder contained herein untrue or incorrect or
         have the effect of preventing or disabling the Stockholder from
         performing the Stockholder's obligations under this Agreement.

         (c) Waiver of Appraisal Rights. The Stockholder hereby waives any and
all rights of appraisal or rights to require the Company to purchase any of the
Shares that the Stockholder may have under the Ohio General Corporation Law.

         Section 3.2 Certain Agreements with Respect to Shares for Purposes of
Rule 145. If the Stockholder may be deemed to be an "affiliate" of the Company
pursuant to Rule 145 under the Securities Act of 1933, as amended, the
Stockholder has delivered, or agrees to deliver to the Parent prior to the
closing of the Merger, an Affiliate Agreement in the form previously approved by
the parties to the Merger Agreement with respect to the Shares and future
transactions with respect to Parent Shares by the Stockholder ("Affiliate
Agreement"). Each representation of the Stockholder made in Section 2.1(b) and
Section 2.1(c) hereof with respect to this Agreement is hereby confirmed to be
true and correct with respect to the Affiliate Agreement, if any.

         Section 3.3 Binding Obligations. The Stockholder agrees that this
Agreement and the Stockholder's obligations hereunder and, if applicable, under

or successors.

         Section 3.4 Stop Transfer. The Stockholder agrees with, and covenants
to, Parent that the Stockholder shall not request that the Company register any
transfer of any certificate representing any of the Shares, if such transfer
would violate any provision of this Agreement.

                                   TERMINATION

         Section 4.1 Termination. This Agreement shall terminate if the Merger

any party for any breach of any covenants, agreements, representations or
warranties contained herein.

         Section 5.1 Entire Agreement; Assignment. This Agreement and the
Affiliate Agreement, if applicable, executed by the Stockholder, (i) constitute
the entire agreement between the parties with respect to the subject matter
hereof and thereof and supersede all other prior agreements and understandings,
both written and oral, between the parties with respect to the subject matter
hereof and (ii) shall not be assigned by operation of law or otherwise without
the prior written consent of the other party; provided that Parent may assign,
in its sole discretion, its rights and obligations hereunder and thereunder to
any direct or indirect wholly owned subsidiary of Parent, but no such assignment
shall relieve Parent of its obligations hereunder if such assignee does not
perform such obligations. Subject to the preceding sentence, this Agreement and
the Affiliate Agreement, if applicable, shall be binding upon and inure to the
benefit of the parties hereto and their respective successors, heirs, personal
representatives, legal representatives and permitted assigns.

         Section 5.2 Amendments. This Agreement may not be modified, amended,
altered or supplemented, except upon the execution and delivery of a written
agreement executed by the parties hereto. The Merger Agreement may be amended in
accordance with the terms thereof, and each reference herein to the Merger
Agreement shall mean the Merger Agreement as amended, provided that any such
amendment that changes the Conversion Number as provided in Section 1.5 of the
Merger Agreement or that in any way materially adversely affects the rights of
the stockholders of the Company shall have been approved in writing by the
Stockholder.

         Section 5.3 Stockholder Capacity. If the Stockholder is or becomes
during the term hereof a director of the Company, then the Stockholder makes no
agreement or understanding herein in his or her capacity as a director. The

         Section 5.5 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Ohio, regardless of the
laws that might otherwise govern under applicable principles of conflicts of
laws thereof.

         Section 5.6 Specific Performance. Each of the parties hereto recognizes
and acknowledges that a breach by it of any covenants or agreements contained in
this Agreement will cause the other party to sustain damages for which there
would be no adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief, in addition to any other
remedy to which such party may be entitled, at law or in equity.

counterparts, each of which shall be deemed to be an original, but all of which

reasonable request and without further consideration, the Stockholder shall
execute and deliver such additional documents and take all such further action
as may be necessary or appropriate to consummate and make effective, in the most
expeditious manner practicable, the agreements, covenants and transactions
contemplated by this Agreement.

         Section 5.10 Severability. Whenever possible, each provision or portion
of any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable,
such invalidity, illegality or unenforceability will not affect any other
provision or portion of any provision, and this Agreement will be reformed,
construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision or portion of any provision had never been contained
herein.

         Section 5.11 Registration Rights Agreement. Prior to the closing of the
Merger, the parties will enter into an agreement for registration of the shares
of Parent Common Stock to be received by Stockholder in the Merger, which
agreement shall provide for one demand registration at the time that Parent
prepares its Annual Report on Form 10-K for the fiscal year ended November 30,
1998 and limited piggyback registration rights and which shall contain other
terms and conditions customary for transactions that are similar to the Merger.

                         REPRESENTATIONS AND WARRANTIEs

         Section 2.1 Representations and Warranties. The Stockholder hereby
represents and warrants to Parent as follows:

         (a) Ownership of Shares. The Stockholder is the record and beneficial
owner of the number of shares of Common Stock, without par value, of the Company
("Common Stock"), as set forth on Schedule A hereto (the "Existing Shares" and,
together with any shares of Common Stock acquired by the Stockholder hereafter
and prior to the termination of this Agreement, whether upon exercise of
options, conversion of convertible securities, purchase, exchange or otherwise,
the "Shares"). On the date hereof, the Existing Shares constitute all of the
shares of Common Stock owned of record or beneficially by the Stockholder.
Except as described on Schedule A attached hereto, the Stockholder has sole
voting power and sole power of disposition, sole power to demand an appraisal of
any Existing Shares entitled to appraisal pursuant to Section 1701.85 of the
Ohio General Corporation Law and sole power to engage in the actions set forth

to all of the Existing Shares, with no restrictions on such rights except
pursuant to the terms of this Agreement.

<PAGE>   3
         (b) Power; Binding Agreement. The Stockholder has the legal capacity,
power and authority to enter into and perform all of the Stockholder's
obligations under this Agreement. The execution, delivery and performance of
this Agreement by the Stockholder will not violate any other agreement to which
the Stockholder is a party or by which the Stockholder or any of the
Stockholder's properties or assets are or may be bound, including, without
limitation, any trust agreement, voting agreement, irrevocable proxy,
stockholders agreement or voting trust. This Agreement has been duly and validly
executed and delivered by the Stockholder and constitutes a valid and binding
agreement of the Stockholder, enforceable against the Stockholder in accordance
with its terms. There is no beneficiary, or holder of a voting trust certificate
or other interest, of any trust of which the Stockholder is a trustee whose
consent is required for the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby with respect to any
Existing Shares. If the Shares constitute community property, this Agreement has
been duly authorized, executed and delivered by, and constitutes a valid and
binding agreement of, each person having community property rights in the
Shares, enforceable against such person in accordance with its terms.

         (c) No Conflicts. Except pursuant to the Securities Exchange Act of
1934, as amended, no filing with, and no permit, authorization, consent or
approval of, any state or federal public body or authority or any other person
(or entity) is necessary for the execution of this Agreement by the Stockholder
and the performance by the Stockholder of the actions contemplated hereby.
Neither the execution and delivery of this Agreement by the Stockholder nor the
consummation by the Stockholder of the transactions contemplated hereby nor
compliance by the Stockholder with any of the provisions hereof will (i) result
in a violation or breach of, or constitute (with or without notice or lapse of
time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the
Stockholder or any of the Stockholder's properties or assets are or may be bound
or (ii) violate any order, writ, injunction, decree, judgment, statute, rule or
regulation applicable to the Stockholder or any of the Stockholder's properties
or assets.

         (d) No Adverse Claims. The Shares and the certificates representing
such Shares are now and at all times during the term of this Agreement will be
held by the Stockholder, or by a nominee or custodian for the benefit of the
Stockholder, free and clear of all liens, claims, security interests, proxies,
voting trusts or agreements, understandings or arrangements or any other
encumbrances whatsoever, except for any such encumbrances or proxies arising
under this Agreement.

         (e) No Brokers. No broker, investment banker, financial advisor or
other person is entitled to receive from the Company or any subsidiary any
broker's, finder's, financial advisor's or other similar fee or commission in
connection with the transactions contemplated hereby based on arrangements made
by or on behalf of the Stockholder.

         (f) Material Reliance. The Stockholder understands and acknowledges
that Parent is entering into, and causing Sub to enter into, the Merger
Agreement in material reliance upon the Stockholder's execution and delivery of
this Agreement.

         (g) No Intention to Dispose. The Stockholder has no plan or intention
to, directly or indirectly, sell, exchange, or otherwise dispose of, reduce the
risk of loss by short sale or otherwise, or enter into any contract or other
arrangement with respect to, or consent to, the sale, exchange or other
disposition of any interest in any shares of Parent Common Stock (as defined in
the Merger Agreement) received pursuant to the Merger. The Stockholder
acknowledges that the Stockholder is giving this representation to enable
Graydon, Head & Ritchey and Sidley and Austin to opine that the Merger
constitutes a reorganization within the meaning of Section 368(a) of the Code
and further recognizes that significant adverse tax consequences might result if
such representation is not true. The Stockholder understands and agrees that, in
connection with the Merger, the Stockholder will give written notice to the
Company and Parent in the event that, at the Effective Time of the Merger (as
defined in the Merger Agreement) there is any change in any of the

proposal that constitutes or that is reasonably likely to lead to any Takeover
Proposal, (B) participate in any discussions (other than as necessary to clarify
the terms and conditions of any unsolicited offer, including any financing or
other contingencies and other relevant facts with respect thereto) or
negotiations regarding any Takeover Proposal (other than with the Stockholder's
legal counsel, other Signatory Stockholders or officers or directors of the

         as set forth on Exhibit A, offer for sale, sell, transfer, tender,
         pledge, encumber, assign or otherwise dispose of (or in any other way
         reduce the Stockholder's risk of ownership in), or enter into any
         contract, option or other arrangement or understanding with respect to
         or consent to the offer for sale, sale, transfer, tender, pledge,

         or enter into any voting agreement with respect to any Shares; or

                  (iii) take any action that would make any representation or
         warranty of the Stockholder contained herein untrue or incorrect or
         have the effect of preventing or disabling the Stockholder from
         performing the Stockholder's obligations under this Agreement.

         (c) Waiver of Appraisal Rights. The Stockholder hereby waives any and
all rights of appraisal or rights to require the Company to purchase any of the
Shares that the Stockholder may have under the Ohio General Corporation Law.

         Section 3.2 Certain Agreements with Respect to Shares for Purposes of

closing of the Merger, an Affiliate Agreement in the form previously approved by
the parties to the Merger Agreement with respect to the Shares and future
transactions with respect to Parent Shares by the Stockholder ("Affiliate
Agreement"). Each representation of the Stockholder made in Section 2.1(b) and
Section 2.1(c) hereof with respect to this Agreement is hereby confirmed to be
true and correct with respect to the Affiliate Agreement, if any.

         Section 3.3 Binding Obligations. The Stockholder agrees that this

or successors.

to, Parent that the Stockholder shall not request that the Company register any
transfer of any certificate representing any of the Shares, if such transfer
would violate any provision of this Agreement.

                                   TERMINATION

         Section 4.1 Termination. This Agreement shall terminate if the Merger

         Section 5.1 Entire Agreement; Assignment. This Agreement and the
Affiliate Agreement, if applicable, executed by the Stockholder, (i) constitute
the entire agreement between the parties with respect to the subject matter
hereof and thereof and supersede all other prior agreements and understandings,
both written and oral, between the parties with respect to the subject matter
hereof and (ii) shall not be assigned by operation of law or otherwise without
the prior written consent of the other party; provided that Parent may assign,
in its sole discretion, its rights and obligations hereunder and thereunder to
any direct or indirect wholly owned subsidiary of Parent, but no such assignment
shall relieve Parent of its obligations hereunder if such assignee does not
perform such obligations. Subject to the preceding sentence, this Agreement and
the Affiliate Agreement, if applicable, shall be binding upon and inure to the
benefit of the parties hereto and their respective successors, heirs, personal
representatives, legal representatives and permitted assigns.

         Section 5.2 Amendments. This Agreement may not be modified, amended,
altered or supplemented, except upon the execution and delivery of a written
agreement executed by the parties hereto. The Merger Agreement may be amended in
accordance with the terms thereof, and each reference herein to the Merger

Merger Agreement or that in any way materially adversely affects the rights of
the stockholders of the Company shall have been approved in writing by the
Stockholder.

construed in accordance with the laws of the State of Ohio, regardless of the
laws that might otherwise govern under applicable principles of conflicts of
laws thereof.

         Section 5.6 Specific Performance. Each of the parties hereto recognizes
and acknowledges that a breach by it of any covenants or agreements contained in

would be no adequate remedy at law for money damages, and therefore each of the
parties hereto agrees that in the event of any such breach the aggrieved party
shall be entitled to the remedy of specific performance of such covenants and
agreements and injunctive and other equitable relief, in addition to any other
remedy to which such party may be entitled, at law or in equity.

reasonable request and without further consideration, the Stockholder shall

as may be necessary or appropriate to consummate and make effective, in the most
expeditious manner practicable, the agreements, covenants and transactions
contemplated by this Agreement.

         Section 5.10 Severability. Whenever possible, each provision or portion
of any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable,
such invalidity, illegality or unenforceability will not affect any other
provision or portion of any provision, and this Agreement will be reformed,
construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision or portion of any provision had never been contained
herein.

         Section 5.11 Registration Rights Agreement. Prior to the closing of the
Merger, the parties will enter into an agreement for registration of the shares
of Parent Common Stock to be received by Stockholder in the Merger, which
agreement shall provide for one demand registration at the time that Parent
prepares its Annual Report on Form 10-K for the fiscal year ended November 30,

         (a) Ownership of Shares. The Stockholder is the record and beneficial

("Common Stock"), as set forth on Schedule A hereto (the "Existing Shares" and,
together with any shares of Common Stock acquired by the Stockholder hereafter
and prior to the termination of this Agreement, whether upon exercise of

voting power and sole power of disposition, sole power to demand an appraisal of
any Existing Shares entitled to appraisal pursuant to Section 1701.85 of the

to all of the Existing Shares, with no restrictions on such rights except
pursuant to the terms of this Agreement.

<PAGE>   3
        (b) Power; Binding Agreement. The Stockholder has the legal capacity,
power and authority to enter into and perform all of the Stockholder's
obligations under this Agreement. The execution, delivery and performance of
this Agreement by the Stockholder will not violate any other agreement to which
the Stockholder is a party or by which the Stockholder or any of the
Stockholder's properties or assets are or may be bound, including, without
limitation, any trust agreement, voting agreement, irrevocable proxy,
stockholders agreement or voting trust. This Agreement has been duly and validly
executed and delivered by the Stockholder and constitutes a valid and binding
agreement of the Stockholder, enforceable against the Stockholder in accordance
with its terms. There is no beneficiary, or holder of a voting trust certificate
or other interest, of any trust of which the Stockholder is a trustee whose
consent is required for the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby with respect to any
Existing Shares. If the Shares constitute community property, this Agreement has
been duly authorized, executed and delivered by, and constitutes a valid and
binding agreement of, each person having community property rights in the
Shares, enforceable against such person in accordance with its terms.

         (c) No Conflicts. Except pursuant to the Securities Exchange Act of
1934, as amended, no filing with, and no permit, authorization, consent or
approval of, any state or federal public body or authority or any other person
(or entity) is necessary for the execution of this Agreement by the Stockholder
and the performance by the Stockholder of the actions contemplated hereby.
Neither the execution and delivery of this Agreement by the Stockholder nor the
consummation by the Stockholder of the transactions contemplated hereby nor
compliance by the Stockholder with any of the provisions hereof will (i) result
in a violation or breach of, or constitute (with or without notice or lapse of
time or both) a default (or give rise to any third party right of termination,
cancellation, material modification or acceleration) under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which the Stockholder is a party or by which the
Stockholder or any of the Stockholder's properties or assets are or may be bound
or (ii) violate any order, writ, injunction, decree, judgment, statute, rule or
regulation applicable to the Stockholder or any of the Stockholder's properties
or assets.

         (d) No Adverse Claims. The Shares and the certificates representing
such Shares are now and at all times during the term of this Agreement will be
held by the Stockholder, or by a nominee or custodian for the benefit of the
Stockholder, free and clear of all liens, claims, security interests, proxies,
voting trusts or agreements, understandings or arrangements or any other
encumbrances whatsoever, except for any such encumbrances or proxies arising
under this Agreement.

         (e) No Brokers. No broker, investment banker, financial advisor or
other person is entitled to receive from the Company or any subsidiary any
broker's, finder's, financial advisor's or other similar fee or commission in
connection with the transactions contemplated hereby based on arrangements made
by or on behalf of the Stockholder.

        (f) Material Reliance. The Stockholder understands and acknowledges
that Parent is entering into, and causing Sub to enter into, the Merger
Agreement in material reliance upon the Stockholder's execution and delivery of
this Agreement.

         (g) No Intention to Dispose. The Stockholder has no plan or intention
to, directly or indirectly, sell, exchange, or otherwise dispose of, reduce the
risk of loss by short sale or otherwise, or enter into any contract or other
arrangement with respect to, or consent to, the sale, exchange or other
disposition of any interest in any shares of Parent Common Stock (as defined in
the Merger Agreement) received pursuant to the Merger. The Stockholder
acknowledges that the Stockholder is giving this representation to enable
Graydon, Head & Ritchey and Sidley and Austin to opine that the Merger
constitutes a reorganization within the meaning of Section 368(a) of the Code
and further recognizes that significant adverse tax consequences might result if
such representation is not true. The Stockholder understands and agrees that, in
connection with the Merger, the Stockholder will give written notice to the
Company and Parent in the event that, at the Effective Time of the Merger (as
defined in the Merger Agreement) there is any change in any of the
representations of the Stockholder set forth in this Section 2.1(g).

                        CERTAIN COVENANTS AND AGREEMENTs

         Section 3.1 Certain Covenants of Stockholder. Except in accordance with
the terms of this Agreement, during the term of this Agreement, the Stockholder
hereby covenants and agrees as follows:

         (a) No Solicitation. (i) The Stockholder will immediately cease and
cause to be terminated all existing discussions and negotiations, if any, with
any parties conducted heretofore by the Stockholder with respect to any Takeover
Proposal. As used in this Agreement, "Takeover Proposal" means any tender offer
or exchange offer for 20% or more of the outstanding shares of Common Stock or
any proposal or offer for a merger, consolidation, amalgamation or other
business combination involving the Company or its subsidiaries or any equity
securities (or securities convertible into equity securities) of the Company, or
any proposal or offer to acquire in any manner a 20% or greater equity or
beneficial interest in, or a material amount of the assets or value of, the
Company or its subsidiaries, other than pursuant to the transactions

FOR IMMEDIATE RELEASE

United Air Specialists, Inc.                             Contact: Sue Kozminski
4440 Creek Road                                                  (513) 891-0400
Cincinnati, OH 45242

               UNITED AIR SPECIALISTS, INC. TO MERGE WITH CLARCOR

         Cincinnati, Ohio, September 24, 1996 (Nasdaq: UASI) -- United Air
Specialists, Inc. ("UAS") today announced that it has signed a definitive
agreement to merge with CLARCOR Inc. (NYSE: CLC) in an exchange of common stock.
UAS is a leader in the design, manufacture and sale of commercial and industrial
environmental products, while CLARCOR is a diversified marketer and manufacturer
of mobile, industrial and environmental filtration products and packaging
products. As a result of the merger, UAS will become a subsidiary of CLARCOR.

         The Boards of Directors of each company unanimously approved the
transaction which will be structured as a merger under which each fully diluted
share of UAS common stock will be converted into 0.36986 shares of common stock
of CLARCOR. The exchange ratio is subject to adjustment based on the actual
number of fully diluted UAS shares outstanding at closing. UAS currently has
approximately 3,270,000 fully diluted shares outstanding. To complete the
merger, CLARCOR will issue approximately 1,210,000 shares of its common stock,
bringing total outstanding shares to approximately 16,090,000.

         CLARCOR had sales of approximately $290 million and net earnings of $22
million for its fiscal year ended November 30, 1995, and expects fiscal year
1996 sales to be approximately $330 million, excluding the UAS acquisition. UAS
had sales of approximately $40 million and net earnings of approximately $1.5
million for its fiscal year ended June 30, 1996.

         Durk Rorie, UAS' President and Chief Executive Officer, said, "We
believe that the merger of UAS and CLARCOR is very positive for the shareholders
and employees of UAS. I doubt we could have found a company with a better
strategic fit for UAS than CLARCOR. There are many complementary operational,
geographic and product opportunities available as a result of the combination of
our two businesses."

         Larry Gloyd, CLARCOR's Chairman and Chief Executive Officer, said, "The
combination of CLARCOR and UAS will significantly strengthen and expand our
presence in the fast-growing environmental and industrial air filtration
industry. In addition, we will have opportunities to
<PAGE>   2
increase shareholder value through business synergies, such as the potential for
filter cartridges manufactured by our Airguard Industries operation to be used
in filter housings manufactured by UAS. We are also very pleased that the UAS
management team and employees, with their tremendous experience in industry and
reputation, will become a part of the CLARCOR team, and we look forward to their
significant contributions."

         Consummation of the merger is subject to, among other things, approval
by the shareholders of UAS and regulatory approvals. It is intended that the
merger qualify as a tax-free reorganization to UAS shareholders and be accounted
for as a pooling of interests. The merger is currently expected to close in
early 1997. The two largest shareholders of UAS, who collectively own
approximately 50% of the outstanding shares, have agreed to vote their shares in
favor of the merger.

         United Air Specialists, Inc., based in Cincinnati, Ohio, is engaged in
the business of manufacturing commercial and industrial air cleaners, energy
recovery systems, fluid contamination equipment and high precision fluid
spraying systems.

         CLARCOR, based in Rockford, Illinois, is a diversified manufacturer and
marketer of mobile, industrial air and environmental filtration products, and
consumer packaging products sold to domestic and international markets.
