                                Recapitalization

      SECTION 2.1 Transactions. On the basis of the representations, warranties,
covenants and agreements and subject to the satisfaction or waiver of the
conditions set forth herein and the terms hereof, each of the parties agrees to
and will consummate, at the Closing, the following transactions in the order set
forth below (collectively, the "Transactions"):

      (a) The Company shall authorize the filing under the laws of the State of
Delaware of the Second Amended and Restated Certificate of Incorporation of the
Company (as amended and restated, the "Certificate of Incorporation") in the
form of Schedule 2.1(a) attached hereto, which shall provide, inter alia, for
preferred stock, par value $.01 per share (the "Preferred Stock"), and common
stock, par value $.01 per share (the "Common Stock").

      (b) The Company shall sell to Buyer, and Buyer shall purchase from the
Company, the number of shares of its Preferred Stock and Common Stock set forth
on Schedule 2.1(b) upon payment of immediately available funds in the amounts
set forth on Schedule 2.1(b) the total purchase price for the shares of
Preferred Stock and Common Stock shall be equal to $188,444,444 (the "Equity
Purchase Price").


                                       -7-
<PAGE>   8

      (c) The Company shall obtain, if and as provided by Buyer, a $200 million
senior secured facility and a $150 million subordinated credit facility
(collectively the "Credit Facility") and incur indebtedness in an amount
satisfactory to consummate the transactions contemplated hereby.

      (d) The Company shall purchase from the Stockholders the number of Shares
set forth opposite each Stockholder's name on Schedule 1.1-A (collectively, the
"Repurchased Shares") for an aggregate purchase price equal to the Redemption
Amount. The "Redemption Amount" shall be equal to the sum of (i) $530 million in
cash, minus (ii) the Equity Rollover Amount and minus (iii) the amount of the
Indebtedness, including the Indebtedness listed on Schedule 2.1(d). The "Equity
Rollover Amount" shall be equal to the sum of $23,555,556 (the value of the
shares of Common Stock and Preferred Stock issued to the Remaining Stockholders
pursuant to subsection (e) below), based on the Equity Purchase Price paid by
Buyer and the Remaining Stockholder's ownership percentage of the Common Stock
and Preferred Stock, such value to be determined on the basis of the per share
price paid by Buyer for the Preferred Stock and the Common Stock purchased by it
pursuant to Section 2.1(b). The Redemption Amount shall be payable in the manner
set forth in Section 2.2.

      (e) In addition to the Redemption Amount paid to the Stockholders pursuant
to Section 2.1(d) above, the Company will issue to each Remaining Stockholder
the number of shares of Preferred Stock and Common Stock set forth opposite such
Remaining Stockholder's name on Schedule 2.1(e) in exchange for the Shares owned
by such Remaining Stockholder.

      (f) After consummation of the Transactions, the Remaining Stockholders and
Buyer will own the number of shares of Preferred Stock and Common Stock set
forth opposite such Person's name on Schedule 2.1(e) attached hereto.

      SECTION 2.2 The Closing.

      (a) The closing of the Transactions (the "Closing") shall take place at
the New York offices of Kirkland & Ellis at 10:00 a.m., local time, on June 30,
1999, or if any of the conditions to the Closing set forth in Article 10 have
not been satisfied or waived by the party entitled to the benefit thereof on or
prior to such date, on the third business day after the satisfaction or waiver
of all of such conditions, or at such other place or on such other date as may
be mutually agreeable to Buyer and the Stockholders (the "Closing Date").

      (b) At the Closing:

            (i) Buyer shall deliver to the Company in immediately available
funds the Equity Purchase Price attributable to the Persons Buyer has designated
and set forth opposite each such Person's name on Schedule 2.1(e) upon the
delivery to Buyer of stock certificates evidencing the


                                       -8-
<PAGE>   9

number of shares of the Preferred Stock and the Common Stock, as set forth
opposite Buyer's name on Schedule 2.1(e).

            (ii) The Company will incur indebtedness under its Credit Facility
in amounts satisfactory to consummate the transactions contemplated hereby and
to fund its ongoing working capital needs.

            (iii) The Company shall deposit $10,000,000 (the "Escrow Amount") in
an escrow account (the "Escrow Account") established pursuant to the terms and
conditions of an escrow agreement (the "Escrow Agreement") in the form of
Schedule 2.2(b)(iii) attached hereto. The Escrow Amount will be available until
the date which is eighteen months after the Closing Date to satisfy any amounts
owed to the Company or Buyer as a result of a breach of certain of the
representations, warranties, covenants and agreements contained herein in
accordance with the Escrow Agreement.

            (iv) The Company shall pay to the Stockholders, by wire transfer of
immediately available funds to an account designated by the Stockholders, an
amount equal to the Redemption Amount less the Escrow Amount upon delivery to
the Company of the stock certificates evidencing the Repurchased Shares duly
endorsed in blank or accompanied by duly executed stock powers.

            (v) The Company shall deliver to each Remaining Stockholder stock
certificate(s) evidencing the shares of Preferred Stock and Common Stock to be
issued to such Remaining Stockholder as indicated on Schedule 2.1(e), and
registered in each such Person's name on the stock records of the Company, upon
delivery to the Company of the stock certificates evidencing the number of
Shares held by each such Person.

      SECTION 2.3 Closing Balance Sheet.

            (a) As promptly as practicable, but no later than 90 days, after the
Closing Date, the Stockholders will cause to be prepared (with the assistance,
as requested, of management of the Company and the Subsidiaries in accordance
with Section 6.1 hereof) and delivered to Buyer the Closing Balance Sheet,
together with an unqualified auditors report of Ernst & Young thereon, and a
certificate based on such Closing Balance Sheet setting forth the Stockholders'
calculation of Closing Stockholders' Equity and the Redemption Amount. The
Closing Balance Sheet (the "Closing Balance Sheet") shall (x) fairly present the
consolidated financial position of the Company and the Subsidiaries as at the
close of business on the Closing Date in accordance with U.S. generally accepted
accounting principles applied on a basis consistent with those used in the
preparation of the Balance Sheet, (y) include line items substantially
consistent with those in the Balance Sheet, and (z) be prepared in accordance
with accounting policies and practices including those described in Schedule 2.3
consistent with those used in the preparation of the Balance Sheet, except that
any liability relating to the Taxes for which the Stockholders are liable to pay
under Section 8.5(a)(iii) shall be excluded. "Closing Stockholders' Equity"
means the


                                       -9-
<PAGE>   10

consolidated stockholders' equity of the Company and the Subsidiaries as shown
on the Closing Balance Sheet; provided that the determination of Closing
Stockholders' Equity shall exclude cash, the Excluded Assets and the proceeds of
any sale thereof prior to Closing, Indebtedness, including the Indebtedness
listed on Schedule 2.1(d), and the items set forth on Schedule 2.4.

            (b) If Buyer disagrees with the Stockholders' calculation of Closing
Stockholders' Equity delivered pursuant to Section 2.3(a), Buyer may, within 30
days after delivery of the documents referred to in Section 2.3(a), deliver a
notice to the Stockholders disagreeing with such calculation and setting forth
Buyer's calculation of such amount. Any such notice of disagreement shall
specify those items or amounts as to which Buyer disagrees, and Buyer shall be
deemed to have agreed with all other items and amounts contained in the Closing
Balance Sheet and the calculation of Closing Stockholders' Equity delivered
pursuant to Section 2.3(a).

            (c) If a notice of disagreement shall be duly delivered pursuant to
Section 2.3(b), Buyer and the Stockholders shall, during the 15 days following
such delivery, use their best efforts to reach agreement on the disputed items
or amounts in order to determine, as may be required, the amount of Closing
Stockholders' Equity, which amount shall not be more than the amount thereof
shown in the Stockholders' calculation delivered pursuant to Section 2.3(a) nor
less than the amount thereof shown in Buyer's calculation delivered pursuant to
Section 2.3(b). If, during such period, Buyer and the Stockholders are unable to
reach such agreement, they shall promptly thereafter cause independent
accountants of nationally recognized standing reasonably satisfactory to Buyer
and the Stockholders (who shall not have any material relationship with Buyer or
the Stockholders) (the "Auditor") promptly to review this Agreement and the
disputed items or amounts for the purpose of calculating Closing Stockholders'
Equity. In making such calculation, the Auditor shall consider only those items
or amounts in the Closing Balance Sheet or the Stockholders' calculation of
Closing Stockholders' Equity and the Redemption Amount as to which Buyer has
disagreed. In making its determination of the Closing Stockholders' Equity and
the Redemption Amount, the Auditor shall be bound by the provisions of this
Agreement. The Auditor shall deliver to Buyer and the Stockholders, as promptly
as practicable, a written report setting forth such calculation. Such report
shall be final and binding upon Buyer and the Stockholders. The cost of such
review and report shall be borne (i) by the Stockholders if the difference
between Final Stockholders' Equity (as defined in Section 2.4(a)) and the
Stockholders' calculation of Closing Stockholders' Equity delivered pursuant to
Section 2.3(a) is greater than the difference between Final Stockholders' Equity
and Buyer's calculation of Closing Stockholders Equity delivered pursuant to
Section 2.3(b); (ii) by Buyer if the first such difference is less than the
second such difference; and (iii) otherwise equally by Buyer and the
Stockholders.

            (d) Buyer and the Stockholders agree that they will, and agree to
cause their respective independent accountants and the Company and each
Subsidiary to, cooperate and assist in the preparation of the Closing Balance
Sheet and the calculation of Closing Stockholders' Equity and in the conduct of
the audits and reviews referred to in this Section 2.3, including without


                                      -10-
<PAGE>   11

limitation, the making available to the extent necessary of books, records, work
papers and personnel.

      SECTION 2.4 Adjustment of Redemption Amount.

            (a) If Base Stockholders' Equity exceeds Final Stockholders' Equity,
the Stockholders shall pay to Buyer, as an adjustment to the Redemption Amount,
in the manner and with interest as provided in Section 2.4(c),the amount of such
excess. If Final Stockholders' Equity exceeds Base Stockholders' Equity, Buyer
shall pay to the Stockholders, in the manner and with interest as provided in
Section 2.4(c), the amount of such excess. "Base Stockholders' Equity" means
$121,601,000, which amount is the consolidated stockholders' equity of the
Company and the Subsidiaries as shown on the Balance Sheet after the exclusion
of cash, the Excluded Assets, Indebtedness, including the Indebtedness listed on
Schedule 2.1(d). and the items set forth on Schedule 2.4. "Final Stockholders'
Equity" means the Closing Stockholders' Equity (i) as shown in the Stockholders'
calculation delivered pursuant to Section 2.3(a), if no notice of disagreement
with respect thereto is duly delivered pursuant to Section 2.3(b), or (ii) if
such a notice of disagreement is delivered, (A) as agreed by Buyer and the
Stockholders pursuant to Section 2.3(c), or (B) in the absence of such
agreement, as shown in the Auditor's calculation delivered pursuant to Section
2.3(c); provided that in no event shall Final Stockholders' Equity be more than
the Stockholders' calculation of Closing Stockholders' Equity delivered pursuant
to Section 2.3(a) or less than Buyer's calculation of Closing Stockholders'
Equity delivered pursuant to Section 2.3(b).

            (b) Any payment pursuant to Section 2.4(a) shall be made at a
mutually convenient time and place within 10 days after the Final Stockholders'
Equity has been determined by delivery by Buyer or the Stockholders, as the case
may be, of a certified or official bank check payable in immediately available
funds to the other party or by causing such payments to be credited to such
account of such other party as may be designated by such other party; provided
that either Buyer or the Stockholders shall have the right, exercisable in its
sole discretion, to pay the other party an advance toward the adjustment to the
Redemption Amount determined in accordance with the first two sentences of
Section 2.4(a) before the actual amount of said adjustment is determined. The
amount and timing of the payment of the advance, if any, shall be determined by
the Stockholders or Buyer, as applicable. Any advance so paid shall be netted
against the actual amounts of adjustments to the Redemption Amount calculated
under Section 2.4(a).

            (c) The amount of any payment to be made pursuant to this Section
2.4 shall bear interest from and including the Closing Date to but excluding the
date of payment at a rate per annum equal to the prime rate as published in The
Wall Street Journal, Midwest Edition, in effect from time to time during the
period from the Closing Date to the date of payment. Such interest shall be
payable at the same time as the payment to which it relates and shall be
calculated daily on the basis of a year of 365 days and the actual number of
days elapsed.

      SECTION 2.5. Pre-Closing or Concurrent Transactions. It is understood and
agreed that prior to, or concurrent with, the Closing, the Company will (i)
distribute the Excluded Assets to the Stockholders in kind as a result of the
Excluded Assets Redemption or otherwise dispose of the Excluded Assets, and
distribute the cash on hand at Closing, and (ii) pay, or cause to be paid, all
performance or sale related bonuses (other than incentive bonuses related to
1999 performance), stock appreciation right payments, option payments, deferred
compensation payments, payments under the Retirement Plan for Outside Directors
and the Supplemental Executive Retirement Plan, and transaction fees, broker's
fees, transfer taxes and related closing expenses owed by the Company
immediately prior to or upon consummation of the transactions contemplated
hereby that are not otherwise allocated between the parties pursuant to the
provisions of this Agreement.

      SECTION 2.6. Adjustment for Deferred Compensation Payments. At or within
two business days after the Closing, the Company will pay to the Seller's
Representative the sum of $2,774,339 representing the agreed lost value of the
Stockholders as calculated on Schedule 2.6 of the tax deductions attributable to
the payments required to be made by the Company under Section 2.5(u) and listed
on Schedule 2.6.

course of business consistent with past practices;

            (e) any making of any loan, advance or capital contributions to or
investment in any Person other than loans, advances or capital contributions to
or investments made in the ordinary course of business consistent with past
practices;

            (f) any transaction or commitment made or any contract or agreement

foregoing, from the date hereof until the Closing Date, except as disclosed on

            (i) agree or commit to do any of the foregoing.

      SECTION 5.2 Other Conduct of the Company. Nothing contained in this

Excluded Assets to the Stockholders or any Affiliate of the Stockholders or to
incur indebtedness for borrowed money so long as the principal amount of such
indebtedness outstanding as of the Closing has been included in the aggregate
principal amount of all indebtedness for borrowed money of the Company and
Subsidiaries on the Closing Balance Sheet and prepayment thereof is permitted
without premium or penalty.

      SECTION 5.3 Access to Information. From the date hereof until the Closing

none of the Company, the Stockholders or any of their respective Subsidiaries,
Affiliates, representatives, officers, employees, directors, or agents will,

assist or participate in or facilitate in any other manner any effort or attempt
by any Person to do or seek to do any of the foregoing; provided that any
transactions contemplated hereby or involving a disposition of the Excluded
Assets shall not constitute a Company Transaction for purposes hereof. The
Company and each Stockholder agrees to notify Buyer immediately if any Person
makes any proposal, offer, inquiry or contact with respect to a Company
Transaction.

      SECTION 5.7 Noncompete and Nonsolicitation. As an inducement to Buyer to
enter into this Agreement and consummate the transactions contemplated hereby,
each of the Stockholders acknowledges and agrees as follows:

            (a) During the period from the Closing Date to and including the
fifth anniversary of the Closing Date (the "Noncompete Period"), no Stockholders
shall have any affiliation (as defined below) with any Person anywhere in the
world which engages in the sale of products sold by the Company and its
Subsidiaries or which competes with the businesses of the Company and its
Subsidiaries, as such products and businesses exist or are in process as of the
Closing Date; provided that nothing contained herein shall be construed to
prohibit any Stockholders from purchasing (i) securities of the Company or (ii)
up to an aggregate of 2% of any class of the outstanding voting securities of
any Person whose securities are listed on a


                                      -29-
<PAGE>   30

national securities exchange or traded in the NASDAQ national market system (a
"Public Company") (including, for purposes of calculating the percentage of such
securities which may be purchased by such Stockholder, the securities of such
Public Company then owned by all Affiliates of such Stockholder to the extent
such Persons are acting in concert or otherwise constitute a "group" for
purposes of Section 13(d)(3) of the Securities Exchange Act of 1934) if such
Stockholder does not have an active role in the management of such Public
Company, it being understood that the exercise of voting rights with respect to
any such voting securities, in and of itself, shall not constitute such a role.
For purposes of this Section 5.7, the term "affiliation" shall mean any direct
or indirect interest in a Person, whether as an officer, director, employee,
investor, partner, stockholder, sole proprietor, trustee, consultant, agent,
representative, broker, promoter or otherwise.

            (b) During the Noncompete Period, each of the Stockholders shall
not, and shall not permit any of his or her Affiliates to (i) induce or attempt
to induce any employee of the Company or its Subsidiaries to leave the employ of
such Company or its Subsidiaries, or in any way interfere with the relationship
between the Company or its Subsidiaries and any employee thereof, (ii) hire
directly or through an Affiliate any person who, to such Person's knowledge, was
an employee of the Company or its Subsidiaries within 180 days prior to the
Closing Date, or (iii) induce or attempt to induce any customer, supplier,
licensee or other business relation of the Company or its Subsidiaries to cease
doing business with the Company or its Subsidiaries or in any way interfere with
the relationship between any such customer, supplier, licensee or business
relation of the Company or its Subsidiaries.

            (c) Notwithstanding anything in this Section 5.7 to the contrary, if
at any time, in any judicial proceeding, any of the restrictions stated in this
Section 5.7 are found by a final order of a court of competent jurisdiction to
be unreasonable or otherwise unenforceable under circumstances then existing,
each Stockholder agrees that the period, scope or geographical area, as the case
may be, shall be reduced to the extent necessary to enable the court to enforce
the restrictions to the extent such provisions are allowable under law, giving
effect to the agreement and intent of the parties that the restrictions
contained herein shall be effective to the fullest extent permissible. The
Stockholders acknowledge and agree that money damages may not be an adequate
remedy for any breach or threatened breach of the provisions of Section 5.7(a)
or Section 5.7(b) and that, in such event, Buyer or its successors or assigns
may, in addition to any other rights and remedies existing in their favor, apply
to any court of competent jurisdiction for specific performance, injunctive
and/or other relief in order to enforce or prevent any violations of the
provisions of this Section 5.7 (including the extension of the Noncompete Period
applicable to any Stockholder by a period equal to the length of court
proceedings necessary to stop such violation); provided that such Stockholder is
found to have been in violation of the provisions of this Section 5.7. Any
injunction shall be available without the posting of any bond or other security.
In the event of an alleged breach or violation by any such Stockholder of any of
the provisions of this Section 5.7, the Noncompete Period will be tolled for any
such Stockholder until such alleged breach or violation is resolved. The
Stockholders agree that the restrictions contained


                                      -30-
<PAGE>   31

in this Section 5.7 are reasonable in all respects. $114,866.25 of the
Redemption Amount is in consideration of the covenants contained in this Section
5.7.

      SECTION 5.8 Real Estate Matters.

            (a) Title Insurance. The Company shall obtain, in preparation for
Closing and shall have delivered to Buyer, a commitment for an ALTA Owners or
Leasehold Policy of Title Insurance, as the case may be, for each parcel of Real
Property located in the United States (the "Title Commitments"), issued by a
title insurer satisfactory to Buyer (the "Title Insurer"), in such amount as
Buyer reasonably determines to be the fair market value (including all
improvements thereon), insuring Buyer's interest in such parcel as of Closing,
subject only to the Permitted Liens. The Company will provide Buyer with title
insurance policies ("Title Policies") on or before the Closing, from the Title
Insurer based upon the Title Commitments. The Company will deliver to the Title
Insurer all affidavits, undertakings and other title clearance documents
necessary to issue the Title Policies and endorsements thereto. Each such Title
Policy will be dated as of the date of Closing and (a) insure title to the
applicable parcels of real estate and all recorded easements benefitting such
parcels, subject only to Permitted Liens, and (b) contain such other
endorsements as Buyer and Buyer's lender, if any, may reasonably request. The
Stockholders shall bear one-half of the expense of the Title Commitments and
Title Policies and Buyer shall bear the other one-half of such expense.

            (b) Surveys. The Company shall obtain in preparation for the
Closing, and shall have delivered to Buyer, current surveys, or documents that
are considered in the country in which the Real Property is located to be the
reasonable equivalent, of the parcels of Real Property listed on Schedule 5.8(b)
(the "Surveys"). The Surveys of Real Property located in the United States shall
be prepared by a licensed surveyor, reasonably satisfactory to Buyer, and
conforming to 1992 ALTA/ACSM Minimum Detail Requirements for Urban Land Title
Surveys and such standards as the Title Insurer may require as a condition to
the removal of any survey exceptions from the Title Policy for said parcel, and
certified to Buyer, Buyer's lender and the Title Insurer. The Stockholders shall
bear one-half of the cost and expense of the Surveys, and Buyer shall bear the
other one-half of such expense.

            (c) Estoppel Letter Prior to Closing, the Company shall obtain an
estoppel and consent letter (the "Estoppel Letter") with respect to each parcel
of Leased Real Property from the landlords, lessors, sublessors or licensors for
such property in form and content reasonably satisfactory to Buyer and Buyer's
lender under the Credit Facility.

      SECTION 5.9 Affiliated Transactions. The Company shall terminate all
Affiliated Transactions prior to or concurrent with the Closing.

      SECTION 5.10 Trusts. For a period of twenty-four months from the Closing
each Stockholder that is a Trust owning in excess of 5% of the outstanding
Shares (i) shall not cause the Trust to be voluntarily dissolved and (ii) shall
make no discretionary distributions of the portion of the


                                      -31-
<PAGE>   32

Redemption Amount received by the Trust unless provision is made that any Person
who receives such distribution acknowledges in writing that the assets received
in said distribution will remain subject to the Stockholders' obligations to the
Buyer hereunder.

      SECTION 6.1 Access; Assistance.

            (a) Buyer agrees that it will cause the Company and each Subsidiary,
on and after the Closing Date, to afford promptly to the Stockholders, and each
of them, and their agents reasonable access to their properties, books, records,
employees and auditors to the extent necessary to permit the Stockholders to
determine any matter relating to their rights and obligations hereunder or to
any period ending on or before the Closing Date; provided that any such access
by the Stockholders shall not unreasonably interfere with the conduct of the
business of Buyer or the Company.

            (b) Buyer agrees that it will cause the management of the Company
and the Subsidiaries to assist the Stockholders and the Seller's Representative
in the preparation of the Closing Balance Sheet to be delivered by the
Stockholders to Buyer in accordance with Section 2.3 hereof and the actions
described in Article 8 hereof.

cause to be done, all things necessary or desirable under applicable laws and

agree, and the Stockholders, prior to the Closing, and Buyer, after the Closing,

parties to any material contracts, in connection with the consummation of the

the receiving party or an affiliate of the receiving party prior to its being
furnished by the Company or a Subsidiary; (ii) in the public domain through no
fault of the receiving party or an Affiliate of the receiving party; or (iii)
acquired on a nonconfidential basis by the receiving party or an Affiliate of

agents in connection with the transactions contemplated by this Agreement so
long as such Persons are informed by the receiving party of the confidential
nature of such information and agree to treat such information confidentially.
The receiving party shall be responsible for any failure to treat such
information confidentially by such Persons. If this Agreement is terminated, the
receiving party and its Affiliates will, and will cause their respective
officers, directors, employees, accountants, lenders, counsel, consultants,
advisors and agents to, destroy or deliver to the delivering party, upon

(including any amended Return) for


                                      -35-
<PAGE>   36

a Post-Closing Tax Period that is inconsistent with any permissible method of
accounting or treatment of items used on a Return for a Pre-Closing Tax Period
as long as such method or item has a reasonable basis under applicable law,
regulation or Taxing Authority guidance and in the event the Buyer and
Stockholders cannot agree as to whether such a method or treatment was
permissible, such dispute shall be resolved by an Accounting Referee whose
costs, fees and expenses shall be borne equally by Buyer and Stockholders,
provided, however, that the Company's treatment of its foreign Subsidiaries as a

Schedule 8.2(c) shall be deemed permissible for purpose of this Section 8.3(a)
unless there is a Final Determination that such treatment is not permissible;
(ii) amend any Return; or (iii) make or change any Tax election; if any of such
actions would give rise to any liability of the Stockholders for Taxes, or under
this Agreement, in respect of any Pre-Closing Tax Period. Buyer covenants that
it will not, and will not cause or permit the Company or any Subsidiary to,
agree or settle or permit the settlement of any liability, or compromise any
claims with respect to Taxes if any of such actions would give rise to any
liability of a Stockholder for Taxes for any Pre-Closing Tax Period or otherwise
under this Agreement without the prior consent of such Stockholder (which
consent shall not be unreasonably withheld). Buyer shall be liable for and shall
pay any and all Taxes resulting from any action referred to in this Section
8.3(a) and Buyer shall indemnify, defend and hold the Stockholders and the
Affiliates harmless against any and all such Taxes.

            (b) Refunds. Buyer shall promptly pay or shall cause prompt payment
to be made to the Stockholders of all refunds of Taxes and interest thereon
received by Buyer, any Affiliate of Buyer, the Company, or any Subsidiary
attributable to Taxes paid by the Stockholders, the Company or any Subsidiary
(or any predecessor or Affiliate of the Stockholders) on or before the Closing
Date and to Taxes paid by the Stockholders pursuant to Sections 8.5(a) and
8.5(b) but only to the extent said refunds and interest exceed the sum of the
amounts reflected in the Closing Balance Sheet for said refunds and interest
plus any interest accruing on such amounts so reflected after the Closing Date.

            (c) Other Taxes. All documentary, sales, use, stamp, registration
and other such taxes and fees (including any penalties and interest) incurred in
connection with this Agreement shall be borne and paid by Buyer, and Buyer will,
at its own expense, file all necessary tax returns and other documentation with
respect to all such taxes and fees, and, if required by applicable law, the
Stockholders will, and will cause their Affiliates to, join in the execution of
any such tax returns and other documentation.

            (d) Method of Proration for Income Tax. Items of income, loss,
deduction or credit shall be apportioned between the Pre-Closing Tax Period and
the Post-Closing Tax Period based on a closing of the books and records of the
relevant entity or entities as of the Closing Date (provided that, for this
purpose, depreciation, amortization and depletion for any Straddle Period shall
be apportioned on a daily pro rata basis). Notwithstanding anything to the
contrary in the preceding sentence, the parties agree that for income tax
purposes, items of income, loss,


                                      -36-
<PAGE>   37

deduction or credit for any Straddle Period shall be apportioned between the
Pre-Closing Tax Period and Post-Closing Tax Period in accordance with U.S.
Treasury Regulations Section 1.1362-3(b), which Regulations shall be reasonably
interpreted by the parties in a manner intended to achieve the method of
apportionment described in the preceding sentence. Further, the performance or
sale related bonuses (other than incentive bonuses related to 1999 performance)
to the extent not deductible under Section 162 of the Code, stock appreciation
rights, option payments, deferred compensation payments, payments under the
Retirement Plan for Outside Directors and the Supplemental Executive Retirement
Plan noted in Section 2.5(ii) will not be deducted in the final S Corporation
return but will be deducted by the Company on its C Corporation return ending
after the Closing.

            (e) No Contrary Elections. The Stockholders and Buyer will not
exercise any option or election (including any election to ratably allocate a
Tax year's items under Treasury Regulation Section 1.1362-3(a)) to allocate Tax
items in a manner inconsistent with Section 8.3(d) hereof.

            (f) Preparation and Filing of Tax Returns. (i) The Stockholders
shall have the right and obligation to timely prepare and file, and cause to be
timely prepared and filed, when due any 1998 and 1999 federal and state income
Tax Return of the Company or any Subsidiary for any period ending prior to the
Closing Date, including, without limitation, all final Returns of the Company as
an "S Corporation" or any Subsidiary which is classified as a "qualified
subchapter S subsidiary" as such terms are defined in Section 1361 of the Code
(hereinafter, "S Corporation" and "QSSS," respectively) for the period beginning
on the first day of the fiscal year of the Company or a Subsidiary, as the case
may be, in which the Closing occurs through and including the day before the
Closing Date. Such Returns shall be prepared in a manner consistent with past
practice and without a change of any election or any accounting method and shall
be submitted by the Stockholders to Buyer (together with schedules, statements
and, to the extent requested by Buyer, supporting documentation) at least 30
days prior to the due date (with regard to extensions) for such Returns. Buyer
shall have the right to review all work papers and procedures used to prepare
any such Return. If Buyer within 10 business days after delivery of any such
Return notifies the Stockholders in writing that it objects to any item in such
Return because the treatment of such item has no reasonable basis, the disputed
items shall be resolved (within a reasonable time, taking into account the
deadline for filing such Return) by a nationally recognized independent
accounting firm chosen by and mutually acceptable to both Buyer and the
Stockholders (an "Accounting Referee"). The costs, fees and expenses of such
Accounting Referee shall be borne equally by Buyer and the Stockholders. Upon
resolution of all such items, the relevant Return shall be adjusted to reflect
such resolution and shall be binding upon the parties without further
adjustment. Buyer and the Stockholders shall cooperate to the end that any such
Returns are filed when due (taking into account any extension of a required
filing date) and Buyer shall thereupon cause an officer of the Company to sign
any such Returns. To the extent that tax accounting for any item is specified in
this Agreement, such tax accounting shall be binding upon the Accounting
Referee.


                                      -37-
<PAGE>   38

      (ii) Buyer shall have the right and obligation to timely prepare and file,
and cause to be timely prepared and filed, when due, all other Returns that are
required to be filed by the Company or any Subsidiary.

      SECTION 8.4 Cooperation on Tax Matters.

      (a) Notice. In the event any income Taxing Authority informs the
Stockholders or their Affiliates, on the one hand, or Buyer, the Company, any
Subsidiary or any Affiliate of Buyer, on the other, of any notice of proposed
audit, claim, assessment or other dispute concerning an amount of Taxes with
respect to which the other party may be liable, the party so informed shall
promptly notify the other party of such matter. Such notice shall contain
factual information (to the extent known) describing any asserted Tax liability
in reasonable detail and shall be accompanied by copies of any notice or other
documents received from any Taxing Authority with respect to such matter.

      (b) Assistance. The Stockholders, on the one hand, and Buyer and the
Company, on the other, shall cooperate (and cause their Affiliates to cooperate)
with each other and with each other's agents, including accounting firms and
legal counsel, in connection with Tax matters relating to the Company or any
Subsidiary, including (i) preparation and filing of Tax Returns; (ii)
determining the liability and amount of any Taxes due or the right to and amount
of any refund of Taxes; (iii) examinations of any Returns; and (iv) any
administrative or judicial proceeding in respect of Taxes assessed or proposed
to be assessed. Such cooperation shall include each party making all information
and documents in its possession relating to the Company and Subsidiaries
available to the other party. Each party also shall make available to the other
parties, as reasonably requested, personnel (including officers, directors,
employees and agents) responsible for preparing, maintaining and interpreting
information and documents relevant to Taxes, personnel necessary to sign Returns
and personnel reasonably required as witnesses or for purposes of providing
information or documents in connection with any administrative or judicial
proceedings relating to Taxes.

      (c) Consent to Settlement. Buyer and the Stockholders shall not agree to
settle or permit the settlement of any liability or compromise any claims with
respect to Taxes, which settlement or compromise may affect the liability for
Taxes (or right to a Tax Benefit) of the other party, without such other party's
consent (which consent may not be unreasonably withheld). Neither Buyer nor the
Stockholders shall make, revoke or amend any Tax election or amend any Return of
the other party, without such other party's consent (which consent may not be
unreasonably withheld), which may affect the other party's liability for Taxes
or right to a Tax Benefit, except as disclosed in Section 8.2(c).

      (d) Defense. The Stockholders may discharge, at any time, its
indemnification obligation under this Article 8 by paying to Buyer the amount of
the applicable loss, calculated on the date of such payment. The Stockholders or
Buyer, as the case may be, may at its own


                                      -38-
<PAGE>   39

expense, participate in and, upon notice to the other party, assume the defense
of any claim, suit, action, litigation or proceeding (including any Tax audit)
for which it may be liable for indemnification hereunder. If the indemnifying
party assumes defense, the other party shall have the right (but not the duty)
to participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the indemnifying party. Whether or not the
indemnifying party chooses to defend or prosecute any claim, all of the parties
hereto shall cooperate in the defense or prosecution thereof.

      SECTION 8.5 Indemnification.

      (a) Taxes Related to Transactions. Notwithstanding anything to the
contrary in this Article 8, the Stockholders shall be liable for and shall pay
when due (i) any and all Taxes imposed on the Stockholders arising in any way in
connection with the sale of the Repurchased Shares; (ii) any Taxes payable by
the Stockholders as shareholders of the Company; and (iii) except for Taxes
payable by the Company under Section 1363(d) of the Code (relating to LIFO
recapture upon an election to be treated as an S Corporation), any corporate
level Taxes imposed upon the Company resulting from the sale of the Repurchased
Shares contemplated by Section 2.1 or the distribution or other disposition of
the Excluded Assets (including without limitation corporate level Taxes imposed
under Section 1374 of the Code), and the Stockholders shall promptly indemnify,
defend and hold Buyer and its Affiliates, and as of the Closing Date, the
Company and any Subsidiary, harmless against any and all such Taxes. To the
extent the distribution or other disposition of Excluded Assets creates a sale
or exchange to the Company for federal or state income tax purposes, the
treatment of such sale or exchange on the Company's Corporation tax returns for
any Pre-Closing Tax Period will not be objected to by Buyer pursuant to Section
8.3(f) as long as such treatment is supported by appraisals conducted by
professional valuation firms.

      (b) Stockholders Liable For Certain Company and Shareholder Level Taxes.
The Stockholders shall be liable for and shall pay when due, and shall promptly
indemnify, defend and hold Buyer and its Affiliates, and as of the Closing Date,
the Company and any Subsidiary, harmless from and against, any and all Taxes
imposed on items of income, loss, deduction or credit which are passed trough to
the Stockholders as shareholders of the Company for any time periods during
which the Company or any Subsidiary is classified as an S Corporation or QSSS,
respectively, and the Stockholders are shareholders of the Company, including,
without limitation, any and all Taxes imposed on items of income, loss,
deduction or credit which are passed through to the Stockholders as shareholders
of the Company under the provisions of Section 1366 of the Code. The
Stockholders shall also indemnify Buyer for (i) any Tax liability of the Company
or any of its Subsidiaries for any Pre-Closing Tax Period attributable to the
failure of any S election or QSSS election to be valid or the termination or
revocation of any such election (except for Taxes payable by the Company under
Section 1363 of the Code relating to LIFO recapture upon an election to be
treated as an S Corporation); (ii) any Tax not paid or accrued for on the
Closing Balance Sheet imposed on the Company or any of its Subsidiaries for any
Pre-Closing Tax Period;


                                      -39-
<PAGE>   40

and (iii) any Tax attributable to the Transactions, and to any other
transactions outside the ordinary course of business not directed by Buyer,
occurring on the Closing Date but prior to the Closing, the liability for which
does not result in an adjustment to the Redemption Amount pursuant to Section
2.4. The Stockholders have the right to defend and take corrective action to
reduce or eliminate such Taxes. Buyer agrees to cooperate in any such effort
taken by the Stockholders or their representatives.

      (c) Stockholders Not Liable For Other Corporate Level Taxes. Except for
those corporate level Taxes expressly treated under Sections 8.5(a) and 8.5(b)
above, the Stockholders shall not be liable for any other Taxes imposed on the
Company or any Subsidiary, including, without limitation, any Taxes payable by
the Company under Section 338 of the Code (relating to a deemed asset sale) or
Section 1363 of the Code (relating to LIFO recapture upon an election to be
treated as an S Corporation) and Buyer, the Company and the Subsidiaries,
jointly and severally, shall promptly indemnify, defend and hold the
Stockholders and their Affiliates harmless from and against any and all such
Taxes.

      (d) Tax Benefit. If either party's indemnification obligation under this
Article 8 arises in respect of an adjustment which makes allowable to the other
party, any of its Affiliates or, as of the Closing, the Company or any
Subsidiary, any deduction, amortization, exclusion from income or other
allowance (a "Tax Benefit") which would not, but for such adjustment, be
allowable, then any indemnification payment shall be an amount equal to (x) the
amount otherwise due but for this Section 8.5(d), minus (y) the amount of any
Tax refunds at the time received or the amount of any reduction in Taxes at the
time realized.

      SECTION 8.6 Adjustments. Any amount paid to or by the Stockholders under
Section 8.3 or 8.5 shall be treated as an adjustment to the Redemption Amount
unless a Final Determination causes any such amount to not constitute an
adjustment to the Redemption Amount for Federal Tax purposes. Any payment
required to be made by Buyer or the Stockholders under Section 8.3 or 8.5 that
is not made when due shall bear interest at the rate per annum determined, from
time to time, under the provisions of Section 662 1(a)(2) of the Code until
paid.

      SECTION 8.7 Survival. The covenants, agreements, representations and
warranties of the parties hereto contained in this Article 8 or in any
certificate or other writing delivered pursuant hereto or in connection herewith
shall survive the Closing for the full period of all statutes of limitations
(giving effect to any waiver, mitigation or extension thereof).

                                      -40-
<PAGE>   41

Buyer or its Affiliate shall provide employees of the Company and the
Subsidiaries ("Employees") with compensation and employee benefits reasonably
comparable in the aggregate to those provided to such Employees immediately
prior to the Closing Date. Notwithstanding the foregoing, this Section 9.1 shall
not apply to any Employee included in a unit of employees covered by a
collective bargaining agreement.

      SECTION 9.2 Service Recognition. Buyer and its Affiliates shall recognize
service with the Company, the Subsidiaries, the Stockholders and their
Affiliates as service for all purposes under any benefit plan maintained by
Buyer or its Affiliates, except for purposes of benefit accrual under any
defined benefit pension plan (other than a defined benefit pension plan
maintained by the Company or a Subsidiary as of the Closing Date). Buyer and its
Affiliates shall credit the dollar amount of all expenses incurred by Employees
and their respective eligible dependents during the applicable plan year in
which occurs the Closing Date, to the extent relevant, for purposes of
satisfying such plan year's deductible and co-payment limitations under any
applicable plan in which such Employees participate after the Closing Date.
Notwithstanding the foregoing, this Section 9.2 shall not apply to an Employee
included in a unit of employees covered by a collective bargaining agreement.

      SECTION 9.3 No Third-Party Beneficiaries. The provisions of this Article 9
shall not create any rights in any Employee or any other person who is not a
party to this Agreement, and no such person shall have any rights as a
third-party beneficiary hereof.

performed by Buyer (or the Company after the Closing) pursuant to this
Agreement; provided that:

      (i) no misrepresentation or breach of warranty made or to be performed by
Buyer (or the Company after the Closing) pursuant to this Agreement where the
Damages in any single instance are less than $10,000 shall give rise to any
liability of Buyer to the Stockholders or their Affiliates,

      (ii) Buyer shall not be liable for breaches of covenants, agreements,
representations and warranties contained in this Agreement (other than Sections
4.1, 4.2, 4.5 and 4.9) unless the aggregate amount of Damages with respect to
all matters for breaches of covenants, agreements, representations and
warranties contained in this Agreement (other than sections 4.1, 4.2, 4.5 and
4.9) exceeds the Deductible and then only to the extent of such excess, and

      (iii) Buyer's maximum liability for breaches of covenants, agreements,
representations and warranties contained in this Agreement (other than Sections
4.1, 4.2, 4.5 and 4.9) shall not exceed the Cap.

      (d) The Company hereby indemnifies the Stockholders and their Affiliates
against and agrees to hold each of them harmless from any and all Damages
incurred or suffered by the Stockholders or any of their Affiliates arising out
of any misrepresentation, or breach of warranty, covenant or agreement made or
to be performed by Buyer pursuant to this Agreement.

      SECTION 11.3 Procedures.

      (a) The Party seeking indemnification under Section 11.2 (the "Indemnified
Party") agrees to give prompt written notice to the party against whom indemnity
is sought (the "Indemnifying Party") of the assertion of any claim, or the
commencement of any action or proceeding ("Claim"), in respect of which
indemnity may be sought for Damages hereunder and will provide the Indemnifying
Party such information with respect thereto that the Indemnifying Party may
reasonably request, including in any case, copies of any summons, complaint or
other pleading which may have been served and any written claim, demand,
invoice, billing or other document evidencing or asserting the Claim, and a good
faith estimate of the amount of the Claim for indemnity. The failure to so
notify the Indemnifying Party shall not relieve the Indemnifying Party of its
obligations hereunder, except to the extent such failure shall have adversely
prejudiced the Indemnifying Party.


                                      -46-
<PAGE>   47

      (b) The Indemnifying Party shall be entitled to participate in the defense
of any Claim asserted by any third party ("Third Party Claim") and, subject to
the limitations set forth in this Section, shall be entitled to control and
appoint lead counsel for such defense in each case at its expense. If the
Indemnifying Party assumes the control of the defense, the Indemnified Party
shall be entitled to employ counsel, at its expense, separate from the counsel
employed by the Indemnifying Party. In any event, the parties shall cooperate in
the defense or prosecution of any Third Party Claim.

      (c) If the Indemnifying Party shall assume the control of the defense of
any Third Party Claim in accordance with the provisions of this Section 11.3,
(i) the Indemnifying Party shall obtain the prior written consent of the
Indemnified Party (which shall not be unreasonably withheld) before entering
into any settlement of such Third Party Claim, if the settlement does not
release the Indemnified Party from all liabilities and obligations with respect
to such Third Party Claim or the settlement imposes injunctive or other
equitable relief against the Indemnified Party and (ii) the Indemnified Party
shall be entitled to participate in the defense of such Third Party Claim and to
employ separate counsel of its choice for such purpose. The fees and expenses of
such separate counsel shall be paid by the Indemnified Party.

      (d) The Stockholders and Buyer shall cooperate, and cause their respective
Affiliates to cooperate, in the defense or prosecution of any Third Party Claim
and shall furnish or cause to be furnished such records, information and
testimony, and attend such conferences, discovery proceedings, hearings, trials
or appeals, as may be reasonably requested in connection therewith.

      (e) The Seller's Representative and Buyer shall make available to each
other, their counsel and accountants all information and documents reasonably
available to them which relate to any Third Party Claim subject to indemnity
hereunder and to render to each other such assistance as may reasonably be
required in order to ensure the proper and adequate defense of any such Third
Party Claim.

      (f) The Seller's Representative and his Deputies (collectively the
"Representatives") shall be free from any liability when acting in good faith in
accordance with any written advice or opinion received from legal counsel, an
independent certified public accountant or other expert rendering advice or an
opinion within the area of his or her expertise. The Representatives shall not
be liable for any mistakes of fact or errors of judgment, or for any acts or
omissions of any kind unless caused by willful misconduct or gross negligence of
the Representatives with regard to their duties under this Agreement. The
Stockholders and Buyer hereby covenant not to sue the Representatives as a
result of any and all loss, damage, liability or expense that the
Representatives may sustain or incur as a result of any action taken in good
faith hereunder and not due to the Representatives' gross negligence or willful
misconduct. The covenant not to sue in this Section 11.3(f) shall survive the
termination of this Agreement.

      SECTION 11.4 Calculation of Damages.


                                      -47-
<PAGE>   48

            (a) The amount of any Damages payable under Section 11.2 by the
Indemnifying Party shall be reduced by the amount of any Tax Benefit realized by
the Indemnified Party arising from the incurrence or payment of the Damages and
shall be net of any amounts recovered or recoverable by the Indemnified Party
under applicable insurance policies.

            (b) The Indemnifying Party shall not be liable under Section 11.2
for any (i) Damages relating to any matter to the extent that (y) there is
included in the Closing Balance Sheet a specific liability or reserve relating
to such matter so long as such liability or reserve is not exceeded or (z) the
Indemnified Party had otherwise been compensated for such matter pursuant to the
Redemption Amount adjustment under Section 2.4 or (ii) consequential or punitive
Damages.

            (c) Notwithstanding any other provision of this Agreement to the
contrary, if on the Closing Date the Indemnified Party has actual knowledge of
any information that would cause one or more of the representations and
warranties made by the Indemnifying Party to be inaccurate as of the date made,
the Indemnified Party shall have no right or remedy after the Closing with
respect to such inaccuracy and shall be deemed to have waived its rights to
indemnification in respect thereof.

      SECTION 11.5 Assignment of Claims. If the Indemnified Party receives any
payment from an Indemnifying Party in respect of any Damages pursuant to Section
11.2 and the Indemnified Party could have recovered all or a part of such
Damages from a third party (a "Potential Contributor") based on the underlying
Claim asserted against the Indemnifying Party, the Indemnified Party shall
assign such of its rights to proceed against the Potential Contributor as are
necessary to permit the Indemnifying Party to recover from the Potential
Contributor the amount of such payment.

      SECTION 11.6 Exclusivity. Except as specifically set forth in this
Agreement, effective as of the Closing Buyer waives any rights and claims Buyer
may have against the Stockholders, whether in law or in equity, relating to the
Company, any Subsidiary or the Shares or the transactions contemplated hereby.
The rights and claims waived by Buyer include, without limitation, claims for
contribution or other rights of recovery arising out of or relating to any
Environmental Law, claims for breach of contact, breach of representation or
warranty, negligent misrepresentation and all other claims for breach of duty.
After the Closing, the provisions of Article 8 and Section 11.2 will provide the
exclusive remedy for any misrepresentation, breach of warranty, covenant or
other agreement (other than those contained in Sections 2.4 and 6.1) or other
claim arising out of this Agreement or the transactions contemplated hereby,
other than for claims of fraud and intentional misrepresentation.

      SECTION 11.7 Escrow Agreement. The Escrow Amount shall be paid pursuant to
the terms and conditions of the Escrow Agreement. The Escrow Agreement provides,
among other


                                      -48-
<PAGE>   49

things, that (a) Buyer shall offset against such cash deposited in the Escrow
Account indemnification payments due under this Article 11, and (b) there shall
be released to the Stockholders on December 31, 2000 the balance of the Escrow
Account, less any indemnification payments made under this Article 11, subject
to the holdback for unresolved claims for which a notice of claim has been given
in accordance with the Escrow Agreement.

                                   TERMINATION

      SECTION 12.1 Grounds for Termination. This Agreement may be terminated at
any time prior to the Closing:

            (a) by mutual written agreement of the Stockholders and Buyer;

            (b) by either the Stockholders or Buyer if the Closing shall not
have been consummated on or before August 31, 1999 so long as the party
terminating this Agreement is not in breach of its obligations under this
Agreement;

            (c) by either the Stockholders or Buyer if consummation of the
transactions contemplated hereby would violate any nonappealable final order,
decree or judgment of any court or governmental body having competent
jurisdiction; or

            (d) by Buyer if the amendments or supplements to the Schedules
pursuant to Section 13.14(b) have, in the aggregate, a Material Adverse Effect.

The party desiring to terminate this Agreement pursuant to clauses 12.1(b),
12.1(c) or 12.1(d) shall give notice of such termination to the other party.

      SECTION 12.2 Effect of Termination. If this Agreement is terminated as
permitted by Section 12.1 such termination shall be without liability of either
party (or any stockholder, director, officer, employee, agent, consultant or
representative of such party) to the other party to this Agreement; provided
that if such termination shall result from the willful (i) failure of either
party to fulfill a condition to the performance of the obligations of the other
party; (ii) failure to perform a covenant of this Agreement; or (iii) breach by
either party hereto of any representation or warranty or agreement continued
herein, such party shall be fully liable for any and all Damages incurred or
suffered by the other party as a result of such failure or breach. The
provisions of Sections 7.4, 13.3, 13.5, 13.6, 13.8, 13.9 and 13.10 shall survive
any termination hereof pursuant to Section 12.1.

      SECTION 13.4 Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their

Transferee expressly agrees in writing to be bound by the terms of this

      SECTION 13.6 Representative of Stockholders.

      (a) One Person (the "Seller's Representative") shall be appointed as
representative of the Stockholders to act for the Stockholders in all matters
with respect to this Agreement and its implementation by a written designation
to that effect signed by all of the Stockholders and delivered to Buyer. Such
written designation shall be signed in any number of counterparts, each of which
shall be an original, with the same effect as if the signature was upon the same
instrument. The name and address of the Person so appointed as Seller's
Representative shall be the name and address of the Seller's Representative set
forth in Section 13.1. Such appointment may be rescinded by written notice
signed by the Stockholders holding in the aggregate more than 50% in interest of
the Shares to that effect delivered to Buyer as provided in Section 13.1 and to
the Person or Persons designated as the Seller's Representative and the other
Stockholders as provided in the written designation by which the Seller's
Representative was appointed; provided that said notice shall include the
designation of a new Seller's Representative.

      (b) The Seller's Representative may, but is not required to, appoint one
Person ("Deputy Seller's Representative") to act in his place and stead on each
and every matter as to which the Seller's Representative shall have power and
authority under this Agreement and the Escrow Agreement. Appointment of a Deputy
Seller's Representative shall be by written designation

                                      -52-
<PAGE>   53

signed by the Seller's Representative and delivered to Buyer. Such appointment
may be rescinded by written notice signed by the Seller's Representative and
delivered to Buyer, and a new Deputy Seller's Representative may be appointed in
the same or in a separate notice. The Seller's Representative may carry out any
of his rights, powers, or responsibilities under this Agreement or the Escrow
Agreement either directly, through the Deputy Seller's Representative, or
through his agents or attorneys.

      (c) Buyer and any other Person may rely on any written notice described in
(a) or (b) in all matters relating to this Agreement and its implementation
unless and until Buyer or such other Person, as the case may be, receives a
notice signed by the holders of more than 50% in interest of the Shares sold by
the Stockholders to the Company hereunder or by the Seller's Representative, as
the case may be.

      (d) The Stockholders hereby authorize the Seller's Representative to
execute on their behalf the Escrow Agreement, the Stockholders Agreement and the
Registration Rights Agreement and any subsequent amendments, modifications or
waivers thereto.

      SECTION 13.7 Buyer's Certificate of Incumbency. Buyer shall deliver to
Seller's Representative as reasonably requested from time to time a certificate
of incumbency in a form reasonably acceptable to Seller's Representative
designating the officer or officers having the authority to act for the Buyer in
matters with respect to this Agreement. The authority of the Persons designated
on said certificate shall be effective until written notice of the recission
thereof is delivered to the Seller's Representative.

      SECTION 13.8 Governing Law. This Agreement shall be governed by and
construed in accordance with the law of the State of Illinois, without regard to
the conflicts of law rules of such state.

      SECTION 13.9 Jurisdiction. Except as otherwise expressly provided in this
Agreement, the parties hereto agree that any suit, action or proceeding seeking
to enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby may only
be brought in the United States District Court for the Northern District of
Illinois or the Circuit Court of Cook County, Illinois, and each of the parties
hereby consents to the jurisdiction of such courts (and of the appropriate
appellate courts therefrom) in any such suit, action or proceeding and
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such suit, action
or proceeding in any such court or that any such suit, action or proceeding
which is brought in any such court has been brought in an inconvenient forum.
Process in any such suit, action or proceeding may be served on any party
anywhere in the world, whether within or without the jurisdiction of any such
court. Without limiting the foregoing, each party agrees that service of process
on Buyer in the case of Buyer, and on the Seller's Representative in the case of
the Stockholders, at the locations provided in Section 13.1 shall be deemed
effective service of process


                                      -53-
<PAGE>   54

on such party.

      SECTION 13.10 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

      SECTION 13.11 Counterparts; Third-Party Beneficiaries. This Agreement may
be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same
instrument. This Agreement shall become effective when each party hereto shall
have received a counterpart hereof signed by the other parties hereto. Each of
the Stockholders shall be deemed to have received a counterpart signed by the
other parties hereto at the time the Seller's Representative has received such a
counterpart. No provision of this Agreement is intended to confer upon any
Person other than the parties hereto any rights or remedies hereunder, except as
permitted by Section 13.4.

      SECTION 13.12 Entire Agreement. This Agreement, the Stockholders
Agreement, the Registration Rights Agreement, the Escrow Agreement and Buyer's
confidentiality agreement dated September 17, 1998 constitute the entire
agreement between the parties with respect to the subject matter of this
Agreement and supersede all prior agreements and understandings, both oral and
written, between the parties with respect to the subject matter of this
Agreement, the Stockholders Agreement, the Registration Rights Agreement, the
Escrow Agreement and said letter agreement.

      SECTION 13.13 Captions. The captions herein are included for convenience
of reference only and shall be ignored in the construction or interpretation
hereof.

      SECTION 13.14 Disclosure Schedules.

      (a) The parties acknowledge and agree that (i) the Schedules to this
Agreement may include certain items and information solely for informational
purposes for the convenience of Buyer and (ii) the disclosure by the
Stockholders of any matter in the Schedules shall not be deemed to constitute an
acknowledgment by the Stockholders that the matter is required to be disclosed
by the terms of this Agreement or that the matter is material. If any Schedule
discloses an item or information in such a way as to make its relevance to the
disclosure required by another Schedule readily apparent, the matter shall be
deemed to have been disclosed in such other Schedule, notwithstanding the
omission of an appropriate cross-reference to such other Schedule.

      (b) From the date hereof until the Closing Date, the Stockholders may
amend and/or supplement the Schedules to this Agreement to reflect events or
changes apparent after the execution of this Agreement.

Company, The Chase Manhattan Bank, Morgan Stanley Dean Witter, Chase Securities
Inc. and other parties, and (ii) a Note Purchase Agreement among Morgan Stanley
Senior Funding, Inc. and Chase Securities Inc. providing for the issuance of

Notes and other instruments, documents, exhibits, schedules, annexes, and
ancillary agreements and certificates executed or delivered by or on behalf of

the "Credit Facility Agreements"). It is agreed that the representations,
warranties, covenants or agreements made pursuant to this Agreement shall be
deemed not to incorporate or otherwise reflect any provisions of the Credit
Facility Agreements.
