ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On September 10, 1999, CLARCOR Inc. ("CLARCOR") entered into a Purchase
Agreement dated September 10, 1999 (the "Purchase Agreement") with Mark IV
Industries, Inc., a Delaware corporation, Facet Holding Co., Inc., a Delaware
corporation, Purolator Products Air Filtration Company, a Delaware corporation,
George W. Dahl Company, Inc., a Delaware corporation, and Mantronics Limited, a
corporation organized under the laws of the United Kingdom (collectively, the
"Sellers"). Pursuant to the terms and conditions of the Purchase Agreement, on
September 10, 1999, CLARCOR acquired substantially all of the assets used by
Sellers in the design, manufacture, marketing and distribution of a complete
line of specialty filters and filtration products primarily for residential,
commercial and industrial use in a wide range of market segments which include
original equipment manufacturers, aftermarket distributors, retail distributors,
contractors and aerospace, marine and military markets. CLARCOR, through its
subsidiaries, intends to continue these businesses to augment its other filter
businesses.

         For financial and accounting purposes the acquisition was deemed to
have occurred on September 1, 1999. The purchase price for such assets was
$136,250,000 plus approximately $8 million from an increase in the net assets of
the businesses acquired (approximately $4,300,000 of which was cash). The
initial purchase price of $136,250,000 was based on the net assets of the
businesses acquired as shown on a February 28, 1999 balance sheet for such
businesses. The purchase price will be subject to a final adjustment based on
the net assets of the businesses shown on a final balance sheet.

         The foregoing description of the Purchase Agreement does not purport to
be complete and is qualified in its entirety by reference to the Purchase
Agreement, a copy of which is filed as Exhibit 2 hereto.

         The purchase price was paid in cash with the proceeds of loans obtained
by CLARCOR pursuant to a Multicurrency Credit Agreement dated as of September 9,
1999 among CLARCOR, Firstar Bank Milwaukee, National Association, Bank One,
Illinois, NA, Amcore Bank N.A., The Northern Trust Company, U.S. Bank National
Association, Suntrust Bank and Associated Bank, Illinois, N.A., Firstar Bank
Milwaukee, National Association, as Agent, and Bank One, Illinois, NA and Amcore
Bank N.A., as Co-agents. Borrowings under the Credit Agreement are unsecured,
but are guaranteed by certain of CLARCOR's subsidiaries. Reference is made to
Exhibit 4 to this Form 8-K for a copy of such Credit Agreement for further
information with respect to the loans thereunder.


         The additional information required to be included in this report
pursuant to the disclosure requirements set forth in Item 2 of Form 8-K is
described in the Press Release filed as Exhibit 99 hereto and is incorporated by
reference herein.

matters in disagreement within ninety (90) days following Mark IV's receipt of

              (f) Notwithstanding anything to the contrary contained in this
Section 2.07, during the period that the determination of the Closing Net Assets
or the Closing Net Cash Balance shall remain in dispute, neither party shall be
required to pay to the other party the amount that would otherwise be payable
hereunder if no such disagreement were to exist, provided, however, that in the
event a net amount in excess of any amount in dispute hereunder shall be due
from one party to the other, such net amount shall be payable pursuant to this
Section as if no such disagreement were to exist.

              (g) During and with respect to the audit and reviews referred to
in this Section 2.07, Sellers and Buyer shall: (i) fully cooperate with all

forth in Schedule 4.17(b), Sellers have previously delivered or made available
to Buyer (i) information relating to statutory employee benefits and (ii) copies
of all other written employee benefit plans and programs maintained or
contributed to in respect of any foreign employee (the "Foreign Employee Benefit

to the knowledge of Sellers, threatened against the Sellers, any Transferred
Subsidiary or any of their affiliates with respect to any Foreign Employee
Benefit Plan.

there is no basis for any claim that any other party to any of the Filter
Business Contracts is in default with respect to its obligations under such
Filter Business Contracts, except for defaults which would individually or in
the aggregate not have a Material Adverse Effect; and

              (e) To the knowledge of Sellers, all other agreements,
arrangements and understandings which any of the Sellers or Transferred
Subsidiaries is a party to are in full force and effect and are valid and
binding obligations of the applicable Transferred Subsidiary, except to the
extent that the



                                       70

soon as practicable thereafter, Mark IV shall amend the terms of the master
defined benefit pension plan maintained by Mark IV and known as the Mark IV

("Filter Participants") shall cease to accrue benefits thereunder for any
purpose on the Closing Date (or such earlier date as Mark IV and Buyer may
subsequently agree to in writing), (b) to provide that



                                       88
<PAGE>   95

of any notices required under ERISA and the Code and the timely filing of all
required filings with any government agency), which are necessary or reasonably
required to effectuate the intent of this Section 6.03.

         6.04 Names. On or prior to the Closing Date or as promptly thereafter
as may be required, each of Facet, PPAFC and G W Dahl shall take all steps
necessary to change its corporate name to a name which does not contain the word

such words.

         6.05 No Solicitation. Sellers shall not and shall take any and all
action necessary to prevent any of their respective directors, officers,
employees or agents and any directors, officers, employees or agents of the
Transferred Subsidiaries from directly or indirectly, encouraging, soliciting,

disposition of all or any material portion of the Filter



                                       89
<PAGE>   96
Business by a sale of capital stock, assets or otherwise (other than pursuant
to this Agreement), or any proposal therefor, or from furnishing or causing to
be furnished any information concerning the Filter Business to any party in
connection with any transaction involving the acquisition of all or any material
portion of the Filter Business by any person other than the Buyer.

         6.06 Non-Competition. As a part of the inducement to Buyer to enter
into this Agreement, Sellers hereby agree that for a period of three (3) years
(the "Covenant Term") from the date hereof, Sellers shall not, nor shall any
division of any of the Sellers or any corporation which Mark IV directly or
indirectly controls the management of or owns more than fifty percent (50%) of
the total number of outstanding shares entitled to vote, or their successors and
assigns (hereinafter referred to as "Sellers' Affiliates"), without the prior
express written consent of the Buyer, own, manage, operate, or control, directly
or indirectly, any business, firm or corporation which is engaged anywhere in
the world in the manufacture or sale of any products which are manufactured and
sold by the Filter Business prior to the Closing Date (hereinafter the
"Products"). Notwithstanding the foregoing, nothing herein shall be deemed to
limit or otherwise restrict the rights of any division, subsidiary or affiliate
of Mark IV which is not engaged in the


                                       90
<PAGE>   97


Filter Business from continuing, after the Closing Date, to conduct its business
in the same manner as such business was conducted prior to the Closing Date.
Ownership or purchase by Mark IV or any of its direct or indirect subsidiaries
at or after the time of Closing, of less than five percent (5%) of the issued
and outstanding capital stock of any enterprise engaged in the production or
sale of Products, the securities of which are listed on a national securities
exchange or included in the national list of over-the-counter securities, shall
not be deemed a violation of this Section 6.06. In addition, Sellers shall not
be deemed to be in violation of this Section 6.06 in the event that, following
the Closing Date, Sellers or any of Sellers' Affiliates acquires substantially
all the assets of any person, firm or corporation or a majority of the issued
and outstanding capital stock of any corporation and, following such
acquisition, less than fifteen percent (15%) of the total annual sales of any
such acquired company is attributable to sales of Products. Upon breach by
Sellers or Sellers' Affiliates of any provision of this Section 6.06, Buyer
shall be entitled to injunctive relief, both preliminarily and permanently,
since the remedy at law would be inadequate and insufficient. Additionally,
Buyer will be entitled to all such other legal and equitable remedies as may be
available to it. In the event any of the provisions of this Section 6.06 are
determined by a court


                                       91
<PAGE>   98

of competent jurisdiction to be contrary to any applicable statute, law or rule,
or for any reason to be unenforceable as written, such court may modify any of
such provisions so as to permit enforcement thereof as thus modified.

         6.07 Collection of Receivables. Following the Closing Date, Sellers
shall take or cause to be taken any action that is reasonably necessary to
assist Buyer in the collection of the accounts receivable of the Filter Business
included within the Assets, including, but not limited to, the endorsement to
Buyer of checks made payable to any Seller, the transfer to Buyer of control of
any of the Filter Business lock boxes for the collection and receipt of payments
made to Sellers arising exclusively from the accounts receivable included within
the Assets and the prompt payment to Buyer of all money received by Sellers with
respect to such accounts receivable. In the same manner, following the Closing
Date Buyer shall promptly remit to Sellers any receivables of Sellers that are
not related to the Filter Business in the event such receivables are received by
Buyer after the Closing Date.

         6.08 Transfer of Non-Filter Businesses. Sellers and Buyer acknowledge
that certain of the Transferred Subsidiaries now own and operate or have in the
past owned and operated certain businesses and the assets and liabilities
associated therewith that are not related to the Filter Business (the
"Non-Filter



                                       92
<PAGE>   99

Businesses") which are generally described on Schedule 6.08. Sellers agree, on
or prior to the Closing of the transactions contemplated by this Agreement, at
their expense, to take any and all action necessary to cause the Non-Filter
Businesses currently owned by such Transferred Subsidiaries and any and all
assets and liabilities associated therewith, to be transferred to an affiliate
of Sellers without recourse, representation or warranty. In addition, Sellers
agree, on or prior to Closing, to take any and all actions necessary to cause
Facet Iberica to transfer certain cash assets of Facet Iberica by dividend to
its shareholders as described on Schedule 6.08. For all purposes of this
Agreement, including, but not limited to, the calculations set forth in Article
2 of this Agreement, all transactions contemplated in this Section shall be
deemed to have occurred prior to the close of business on August 31, 1999 and
shall be taken into account in determining Closing Net Assets for purposes of
the calculations set forth in said Article 2. Except to the extent taken into
account in determining Closing net Assets, all Taxes (including Transfer Taxes)
resulting from the transfers and dividends contemplated by this Section 6.08
shall be paid by Sellers.

         6.09 Audited Financial Statements. Sellers shall take such actions as
shall be necessary at Sellers' expense to prepare audited consolidated balance
sheets and statements of operations



                                       93
<PAGE>   100

of the Filter Business (the "Audited Financial Statements") for the three fiscal
years ending February 28, 1999. The Audited Financial Statements shall comply
with the requirements of Regulation S-X promulgated by the Securities and
Exchange Commission. The Audited Financial Statements shall be delivered to
Buyer not later than 45 days after the Closing and Buyer agrees to cooperate to
the extent reasonably necessary after the Closing in the preparation of such
statements.

                          ARTICLE 7 COVENANTS OF BUYER

         7.01 Employees and Employee Benefit Plans.

              (a) Subject to the obligations of Buyer which arise under the
Collective Bargaining Agreements, Buyer shall offer employment (at the base
compensation and wage levels as Buyer shall determine) to each of the employees
of the filter division of Facet and of PPAFC, who is actively employed as of the
Closing Date (the "Filter Division Employees"). Each of the employees of the
Transferred Subsidiaries on the Closing Date shall continue in the employment of
the applicable Transferred Subsidiary. Those Filter Division Employees who
accept Buyer's offer of employment and employees of the Transferred Subsidiaries
as of the Closing Date are referred to herein as "Transferred Employees."
Notwithstanding anything herein to the contrary, nothing in this Agreement shall
create any obligation



                                       94
<PAGE>   101

on the part of Buyer to continue the employment of any employee for any definite
period following the Closing. Buyer shall offer employment to any individual who
was an employee of the Filter Business and who is either (i) receiving
sick-leave or short-term disability benefits under Seller's sick-leave or
short-term disability program or who is on an approved leave of absence as of
the Closing and (ii) is entitled to reinstatement under applicable federal or
state law, in each case under clause (i) or (ii) subject to the following
conditions (except to the extent that such conditions are not applicable to the
reason for such person's absence): (i) such individual is released by his or her
physician to return to active employment; (ii) such individual actually returns
to active employment immediately upon such release and (iii) such release is
prior to such individual's becoming eligible for long-term disability benefits
under Seller's long-term disability program, provided, however, that no
individual shall be offered employment under this provision after six months
following the Closing or any applicable period as required by law, if longer.
Any employee who accepts Buyer's offer of employment pursuant to the immediately
preceding sentence shall not become an employee of the Buyer until such employee
actually returns to active employment.

<PAGE>   102

              (b) The Buyer hereby agrees that, at all times during the one (1)
year period following the Closing Date (the "Benefit Continuation Period"), the
Buyer shall take such action as may be necessary to maintain and provide for the
United States and foreign employees of the Filter Business, benefits under
personnel practices, employee welfare plans and employee pension plans which in
the aggregate are reasonably comparable to the employee welfare plans, the
employee pension plans and the foreign benefit plans, as applicable which were
provided to such employees of the Filter Business on the Closing Date as more
particularly set forth in Schedule 4.17(a) and Schedule 4.17(b) attached hereto,
including, without limitation, certain supplementary pension policies for
employees of Facet UK, provided, that Buyer shall have the right to make any
amendment to or adjustment in any such employee benefits as may be necessary, in
Buyer's judgment, either to be in accord with any existing employee welfare plan
or employee pension plan that may be applicable to other employees of the Buyer
or to comply with any applicable law.

              (c) Buyer shall credit Transferred Employees with any amounts paid
under Seller's Plans prior to the Closing Date toward satisfaction of the
applicable deductible amounts and copayment minimums under the corresponding
welfare plans of Buyer, but only to the extent such payments would be taken into



                                       96
<PAGE>   103

account under the welfare plans maintained by Buyer with respect to similarly
situated employees.

              (d) No provision of this Section 7.01 shall create any third-party
beneficiary rights in any employee or former employee (including any beneficiary
or dependent thereof) of Sellers or the Transferred Subsidiaries, any of their
respective affiliates, Buyer or any affiliates of Buyer in respect of continued
employment (or resumed employment) for any specified period of any nature or
kind whatsoever, and no provision of this Section 7.01 shall create such
third-party beneficiary rights in any such persons in respect of any benefits
that may be provided, directly or indirectly, under any employee benefit plan or
arrangement, including the currently existing Non-ERISA Plans, Compensation
Commitments, Plans and Foreign Employee Benefit Plans.

              (e) Anything herein to the contrary notwithstanding, no employee
of any of the Sellers shall become an employee of Buyer or any of its affiliates
until the Closing Date and, until the Closing Date and the consummation of the
transactions called for by this Agreement, neither the Buyer nor any of its
affiliates shall have any liability with respect to any such employees, except
with respect to any payroll expense (including Taxes thereon) and any employee
benefit and pension expense



                                       97
<PAGE>   104

allocable to the period between the Closing Balance Sheet Date and the Closing
Date.

         7.02 Insurance Coverage. Buyer acknowledges that the insurance coverage
which Sellers maintain with respect to the Filter Business including, without
limitation, general liability, product liability, auto liability, property,
commercial umbrella, excess umbrella, aircraft products, fiduciary liability,
crime liability, workers compensation and medical stop loss insurance coverage
is maintained by Mark IV under policies with respect to which Mark IV is the
named insured and the other Sellers and the Transferred Subsidiaries are
additional insureds. Buyer acknowledges that, effective as of the Closing Date,
Mark IV intends to remove the Filter Business from the insurance coverage
provided by such insurance policies. Accordingly, Buyer acknowledges that
Sellers' insurance protection shall not be available to Buyer with respect to
any injury, loss or damage which Buyer, any of the Transferred Subsidiaries, the
Filter Business or any third party may suffer as a result of any event,
occurrence or circumstance existing or occurring with respect to the Filter
Business at any time on or after the Closing Date. Sellers confirm and
acknowledge that Sellers' insurance protection, subject to any policy
limitations and deductibles contained therein, shall be

available with respect to events, occurrences or circumstances exiting or
occurring at any time prior to the Closing Date.

         7.03 Letters of Credit, Performance Bonds, etc. Buyer shall promptly
after Closing deliver to Sellers replacement letters of credit for those letters
of credit or bonds set forth on Schedule 7.03 and shall use its reasonable
efforts to deliver to Sellers replacement performance bonds, payment bonds, bid
bonds, guarantees and similar instruments, in an aggregate principal amount and
with terms and from banks or other financial institutions or surety companies in
each case reasonably satisfactory to both parties hereto, to replace (or, to the
extent required as described above, to collateralize) any performance bonds,
payment bonds, bid bonds, guarantees and similar instruments of Sellers or any
of the Transferred Subsidiaries relating to the Filter Business. If the
beneficiary thereof will not permit replacement, Buyer shall indemnify and hold
Sellers harmless from any liability (other than any liability not in the
ordinary course arising from an action or inaction by any of the Sellers or by
the Transferred Subsidiaries prior to the Closing Date) arising from any such
performance bonds, payment bonds, bid bonds, letters of credit, guarantees and
similar instruments of Sellers or any of the Transferred Subsidiaries relating
to the Filter Business (except for those letters of credit set forth on Schedule
7.03, which



                                       99
<PAGE>   106

must be replaced or collateralized by Buyer prior to or at the Closing) referred
to in this Section 7.03.

         8.05 Tax Matter Covenants

              (a) Indemnification by Sellers. For purposes of this section,
Taxes taken into account in determining Closing Net Assets for purposes of the
calculations set forth in Article 2 hereof shall be deemed to be paid by
Sellers. Sellers jointly and severally shall be responsible for, shall pay or
cause to be paid, and shall indemnify and hold harmless Buyer and its affiliates
in the manner described in this Section 8.05 from and against (and shall be
entitled to any refund of) each of the following:

                   (i) to the extent not previously paid, any and all Taxes with

         excluding all transactions entered into by any Transferred Subsidiary
         occurring on the Closing Date and after the Closing which are not
         related to the transactions contemplated by this Agreement ("Excluded
         Transactions");



                                      103
<PAGE>   110

                   (ii) without duplication, to the extent not previously paid,
         any and all Income Taxes resulting from the Sellers or any Transferred
         Subsidiary having been (or ceasing to be) included in any affiliated,
         consolidated, combined or unitary Tax Return or tax group that included
         the Sellers or any Transferred Subsidiary for any taxable period (or
         portion thereof) ending on or before the Closing Date (including,
         without limitation, any liability for Taxes resulting from an
         acceleration of an "intercompany transaction," within the meaning of
         Treasury Regulation section 1.1502-13 or 1.1502-14 (or any similar
         provision under state, local or foreign law or any predecessor
         provision or regulation), that occurred on or before the Closing Date
         (but excluding the Excluded Transactions);

                   (iii) without duplication, to the extent not previously paid,
         any and all Income Taxes of any member of an affiliated, consolidated,
         combined or unitary group (other than the Sellers or the Transferred
         Subsidiaries) of which the Sellers or any Transferred Subsidiary is or
         was a member on or prior to the Closing Date, by reason of the
         liability of the Sellers or any Transferred Subsidiary pursuant to
         Treasury Regulation section 1.1502-6(a) or any analogous or similar
         provision under state, local or foreign law or any predecessor
         provision or regulation;


                                      104
<PAGE>   111

                   (iv) without duplication, to the extent not previously paid,
         any and all employment and withholding taxes with respect to the Filter
         Business for tax periods ending on or before the Closing Date;

                   (v) to the extent not previously paid, any and all Taxes
         allocable to taxable periods beginning before and ending after the
         Closing Date ("Straddle Period"), allocable to the Sellers pursuant to
         Section 8.05(c), whenever paid or assessed, including as a result of
         any action, suit, investigation, audit, claim, assessment or amended
         Tax Return; and

                   (vi) to the extent not previously paid, and notwithstanding
         anything herein to the contrary, all Taxes imposed on, relating to or
         measured by the ownership or operation of the Non-Filter Businesses by
         the respective Transferred Subsidiaries and all Taxes (including
         Transfer Taxes) attributable to the transfers and dividends
         contemplated in Schedule 6.08 (the "Non-Filter Business Taxes"),
         whenever incurred or assessed, including as a result of any action,
         suit, investigation audit, claim, assessment or amended Tax Return. It
         is understood that (x) in determining Closing Net Assets for purposes
         of the calculations set forth in Article 2 hereof, there shall be taken
         into account Spanish withholding taxes with respect



                                      105
<PAGE>   112

         to the distribution of a dividend by Facet Iberica to its shareholders
         described in said Schedule 6.08 as well as an estimate of all other
         Taxes (including Transfer Taxes) allocated to Sellers pursuant to
         Sections 6.08, 8.05 and 8.12 hereof with respect to the other transfers
         contemplated by Schedule 6.08, (y) Buyer and Sellers shall cooperate in
         causing Facet Iberica to pay over to the appropriate governmental
         authority on a timely basis the withholding taxes described in clause
         (x) with respect to the distribution of a dividend by Facet Iberica to
         its shareholders, and (z) Sellers shall be responsible for any
         additional (and shall be entitled to a refund of any excess)
         withholding taxes or other Taxes with respect to such distribution and
         other transfers, whenever incurred or assessed, including as a result
         of any action, suit, investigation, audit, claim, assessment or amended
         Tax Return, administrative or court proceeding. Notwithstanding
         anything contained in this Agreement to the contrary, to the extent the
         amount of any Spanish withholding taxes allocated to Sellers as
         provided above, with respect to any dividend to Facet UK or Facet
         Italiana actually provides a tax benefit to Buyer or any Transferred
         Subsidiary, such benefit shall offset and reduce the liability of
         Sellers for Taxes for the applicable Straddle



                                      106
<PAGE>   113

         Period as provided in Section 8.05(c) of this Agreement or for Taxes
         resulting from the transactions contemplated by Schedule 6.08,
         (provided that any such benefit shall not be greater than the initial
         Taxes withheld on the dividend from Facet Iberica to each respective
         country).

If, as a result of any action, suit, investigation, audit, claim, assessment or
amended Tax Return, there is any change after the Closing Date in an item of
income, gain, loss, deduction, credit or amount of Tax that results in an
increase in a Tax liability for which Sellers would otherwise be liable pursuant
to this Section 8.05(a), and such change actually results in a decrease in the
Tax liability of a Transferred Subsidiary, Buyer or any affiliate or successor
of any thereof for any taxable year or period beginning after the Closing Date
or for the portion of any Straddle Period beginning after the Closing Date,
Sellers and the Transferred Subsidiaries shall not be liable with respect to
such increase to the extent of such decrease (and, to the extent such increase
in Tax liability is paid to a taxing authority by Sellers or any affiliate
thereof, Buyer shall pay Sellers an amount equal to such decrease).

              (b) Indemnification by Buyer. Buyer agrees to indemnify and hold
harmless the Sellers from and against (and Sellers and its affiliates shall have
no liability under this Agreement on account of) Taxes of the Transferred
Subsidiaries



                                      107
<PAGE>   114

that are not allocated to Sellers pursuant to Section 8.05(a) (including Taxes
resulting from an Excluded Transaction).

              (c) Allocations. Sellers and Buyer shall, to the extent permitted
by applicable law, elect with the relevant taxing authority to close the taxable
period of the Sellers and the Transferred Subsidiaries on the Closing Date. In
any case where applicable law does not permit a Seller or any Transferred
Subsidiary to close its taxable year on the Closing Date, Taxes (other than
Taxes described in Section 8.05(a)(vi)) attributable to a Straddle Period
(including any Tax resulting from any action, suit, investigation, audit, claim,
assessment or amended Tax Return) shall be allocated (y) to Sellers for the
period up to and including the Closing Date, but excluding any Excluded
Transaction, and (z) to Buyer for the period subsequent to the Closing Date
(including any Excluded Transaction). Any allocation required to determine any
Taxes (other than property Taxes and other Taxes not susceptible to allocation
based on a closing the books basis and Taxes described in Section 8.05(a)(vi))
attributable to any Straddle Period shall be made by means of a closing of the
books and records of each of the Sellers and the Transferred Subsidiaries as of
the close of business on the Closing Date, and, to the extent of Taxes not
susceptible to such allocation, by apportionment on the basis of elapsed days,
and to the extent attributable to any Excluded


                                      108
<PAGE>   115

Transaction, shall be allocated to the period subsequent to the Closing Date. An
estimate of all Taxes allocated to Sellers pursuant to Section 8.05(a) for the
Straddle Period Taxes shall be included as liabilities on the Closing Balance
Sheet in accordance with the procedures set forth in Article 2 of this
Agreement.

              (d) Procedure for Tax Claims.

                   (i) Promptly after receipt by Buyer or its affiliates of
         written notice of the assertion or commencement of any claim, audit,
         examination, or other proposed change or adjustment by any taxing
         authority concerning any Tax allocated to Sellers pursuant to Sections
         6.08, 8.05(a) and 8.12 (each a "Tax Claim"), Buyer shall notify
         Sellers. Such notice shall contain factual information (to the extent
         actually known by Buyer or any Transferred Subsidiary) describing the
         asserted Tax Claim in reasonable detail and shall include copies of any
         notice or other document received from any taxing authority in respect
         of any such asserted Tax Claim. The failure of Buyer to give Sellers
         prompt notice as provided herein shall not relieve Sellers of any of
         their obligations under Section 8.05(a), except to the extent that the
         Sellers are substantially prejudiced by such failure.


                                      109
<PAGE>   116


                   (ii) Sellers shall have the sole right to represent Sellers
         or any Transferred Subsidiary's interests in any Tax audit or
         administrative or court proceeding ("Contest") relating to any Tax
         allocated to Sellers pursuant to Section 8.05(a), so long as Sellers
         shall have acknowledged in writing their indemnity obligation to Buyer
         if the Contest should prove unsuccessful, provided that to the extent
         that the resolution of any issue in such Contest could adversely and
         significantly affect the interests of any Transferred Subsidiary, Buyer
         or any affiliate or successor of any thereof for any taxable year or
         period beginning after the Closing Date (or for the portion of any
         Straddle Period beginning after the Closing Date) Buyer shall be
         entitled to participate (but not control) in good faith with Sellers in
         Contesting such issue. Each of Buyer and Sellers shall bear the cost of
         their respective counsel, accountants or other representatives engaged
         by them to conduct any Contest with respect to Taxes.

                   (iii) Sellers shall promptly notify Buyer of the commencement
         of any claim, audit, examination or other proposed change or adjustment
         by any taxing authority which could reasonably be expected to affect
         the liability of Buyer or any Transferred Subsidiary or any of Buyer's
         affiliates for Taxes and Sellers shall keep Buyer duly





                                      110
<PAGE>   117

         informed of the progress of any Contest conducted by Sellers pursuant
         to Section 8.05(d)(ii).

              (e) Preparation of Tax Returns.

                   (i) Sellers shall properly prepare or cause to be properly
         prepared in a manner consistent with past practices and prior
         adjustments, and shall timely file or cause to be timely filed (after
         taking into consideration any available extensions for the filing of
         such Tax Returns), all separate, consolidated, combined or unitary Tax
         Returns for Income Taxes and other Taxes, which include Sellers or any
         of the Transferred Subsidiaries or their assets or operations and which
         are required to be filed with respect to any taxable period ending on
         or before the Closing Date.

                   (ii) Except as set forth in Section 8.05(e)(i) above, Buyer
         shall be responsible for the preparation, filing and payment of all
         other Tax Returns required to be filed (taking into account all timely
         extensions) after the Closing Date by or on behalf of the Transferred
         Subsidiaries, or with respect to their assets or operations.

                   (iii) With respect to any Tax Return required to be filed by
         Buyer with respect to a Straddle Period pursuant to Section 8.05(e)(ii)
         (a "Straddle Period Tax



                                      111
<PAGE>   118

         Return"), Buyer shall prepare such return in a manner consistent with
         past practices and prior audit adjustments (other than with respect to
         items which Buyer in good faith determines have been erroneously
         treated in prior returns filed by Sellers or the Transferred
         Subsidiaries). Sellers shall submit to Buyer not less than thirty (30)
         business days prior to the applicable filing date for any Straddle
         Period Tax Return, Seller's proposed treatment of the Non-Filter
         Business Taxes which, in the case of the transfers referred to in
         Schedule 6.08, shall be in accordance with the provisions
         outlined in Schedule 6.08. Such treatment shall, to the extent it
         relates to the operations (as opposed to the transfers)
         of the Non-Filter Businesses shall be prepared in a manner consistent
         with past practices and prior audit adjustments. To the extent that
         Buyer disagrees with Seller's proposed treatment of Non-Filter Business
         Taxes, Buyer and Seller shall attempt to resolve such differences, but,
         subject to this Section 8.05(e), the ultimate decision as to how the
         Straddle Period Tax Return is prepared with respect to Non-Filter
         Business Taxes shall be made by the Sellers. In connection with its
         submission of its proposed treatment of the operations and transfers of
         the Non-Filter Businesses, Sellers shall furnish to Buyer such
         information as Buyer or



                                      112
<PAGE>   119

         its representatives shall reasonably request. Buyer shall deliver, at
         least fifteen (15) days prior to the due date for filing each such Tax
         Return (taking into account all timely extensions), to Sellers a draft
         of such Straddle Period Tax Return and a statement setting forth in
         reasonable detail the amount of Taxes allocated to Sellers pursuant to
         Sections 6.08, 8.05(c) and 8.12 and all items which Buyer has
         determined to have been treated inconsistently with past practices and
         prior adjustments or erroneously treated in prior years by the Foreign
         Subsidiaries or not in accordance with Schedule 6.08 (the "Tax
         Statement"). Sellers shall have the right to review such draft Tax
         Return and the Tax Statement prior to the filing of such Tax Return and
         to suggest any reasonable changes to such Tax Return. Sellers and Buyer
         agree to consult and resolve in good faith any issue arising as a
         result of the review of such draft Tax Return and the Tax Statement and
         mutually to consent to the filing as promptly as possible of such Tax
         Return. In the event the parties are unable to resolve any dispute with
         respect to any Straddle Period within five (5) business days following
         the delivery of such draft Tax Return and the Tax Statement, the
         parties shall jointly request a Tax Settlement Auditor (appointed
         pursuant to the principles of Section 8.05(i))



                                      113
<PAGE>   120

         to resolve such issue in dispute as promptly as possible. If the Tax
         Settlement Auditor is unable to make a determination with respect to
         any disputed issue within five (5) business days prior to the due date
         (including any timely extension) for the filing of the Tax Return in
         question, then Buyer may file such Tax Return on the due date
         (including any timely extension) therefor without such determination
         having been made and without Sellers' consent, provided that such Tax
         Return shall be prepared in a manner which Buyer determines in good
         faith to be consistent with past practices and audit adjustments.
         Notwithstanding the filing of such Tax Return, the Tax Settlement
         Auditor shall make a determination with respect to any disputed issue
         and the amount of Taxes that are allocated to Sellers pursuant to
         Sections 6.08, 8.05(c) and 8.12 shall be as determined by the Tax
         Settlement Auditor. In the event the Taxes on the Straddle Period Tax
         Return for the period beginning with the commencement of the Straddle
         Period and ending on the Closing Date determined as provided above or
         as finally determined by an audit or examination by any relevant taxing
         authority shall be less or more than the amount of Taxes paid by
         Sellers (including any amounts for such Taxes taken into account in
         determining Closing Net Assets for purposes of the



                                      114
<PAGE>   121

         calculations set forth in Article 2 hereof and any adjustments for
         benefits with respect to the withholding Taxes referred to in Schedule
         6.08 and Section 8.05(a)(vi), Buyer or Sellers, as the case may be,
         shall pay the amount of such difference to the other party within five
         (5) business days after the final determination of such Straddle Period
         Taxes.

                   (iv) Sellers and Buyer shall cooperate fully with each other
         and make available to each other in a timely fashion such Tax data and
         other information as may be reasonably required by Sellers or Buyer for
         the preparation and timely filing of any Tax Return required to be
         prepared and filed by the other party hereunder, or in connection with
         the preparation or filing of any election, claim for refund, consent or
         certification.

                   (v) Neither Buyer nor any of its affiliates shall (or shall
         cause or permit any Transferred Subsidiary to) amend, refile or
         otherwise modify (or grant an extension of any statute of limitation
         with respect to) any Tax Return relating in whole or in part to Sellers
         or any Transferred Subsidiary with respect to any taxable year or
         period ending on or before the Closing Date, to the extent that Sellers
         conclude in good faith that the proposed amendment, refiling, or
         modification of such Tax Return



                                      115

         could adversely and significantly affect Sellers' liability hereunder)
         without the prior written consent of Sellers, which consent may be
         withheld in the reasonable discretion of Sellers.

                   (vi) Buyer shall promptly cause each Transferred Subsidiary
         to prepare and provide to Sellers a package of Tax information
         materials, including, without limitation, schedules and work papers
         (the "Tax Package") required by Sellers to enable Sellers to prepare
         and file all Tax Returns required to be prepared and filed by Sellers
         pursuant to this Section 8.05(e). The Tax Package shall be completed in
         accordance with past practice and prior audit adjustments. Buyer shall
         cause the Tax Package to be delivered to Sellers within ninety (90)
         days after the Final Purchase Price has been determined.

              (f) Access to Information. Sellers and Buyer shall provide to each
other, and Buyer shall cause each of the Transferred Subsidiaries to provide to
Sellers, reasonable access, at any reasonable time and from time to time, at the
business location at which the books and records are maintained, after the
Closing Date, to such Tax data of each of the Transferred Subsidiaries and the
Sellers as Sellers or Buyer, as the case may be, may from time to time
reasonably request and shall furnish, and request the independent accountants
and legal



                                      116
<PAGE>   123

counsel of Sellers, Buyer, or any Transferred Subsidiary to furnish to
Sellers or Buyer, as the case may be, such additional Tax and other information
and documents in the possession of such persons as Sellers or Buyer may from
time to time reasonably request.

              (g) Timing of Indemnity Claims; Exclusive Remedy. Any claim for
indemnity under this Section 8.05 and with respect to any Taxes on Non-Filter
Business Transfers as provided in Section 8.05(c) must be made prior to sixty
(60) business days after the expiration of the applicable Tax statute of
limitations with respect to the relevant taxable period (including all
extensions obtained, whether automatic or permissive). The indemnities provided
for in Sections 8.05(a) and (c) together with the Sellers' obligations to file
Tax Returns and make payments pursuant to this Section 8.05 shall not duplicate
Sellers' obligations with respect to any breach of their representations set
forth in Section 4.22.

              (h) Procedure for Indemnity Claims. The party seeking
indemnification or other payment pursuant to this Section 8.05 (Sellers or
Buyer, as the case may be) shall give the other party written notice of claim
for indemnification or payment, which notice shall include a calculation of the
amount of the requested indemnity or other payment and shall furnish to the
other party copies of all books, records and other



                                      117
<PAGE>   124

information reasonably requested by the other party to the extent necessary to
substantiate such claim and verify the amount thereof. If reasonably necessary
in order to make or substantiate a claim (or to determine if a claim should be
made), each party shall be permitted reasonable access to the other party's
books, records and other information in connection therewith, provided that
neither party shall be required to provide the other party access to information
(such as the portion of any consolidated or combined Income Tax Return) which
includes information or data unrelated to the Transferred Subsidiaries (or in
the case of Sellers or Buyer, unrelated to the Filter Business). The party
requested to make any indemnity payment pursuant to this Section 8.05 shall
deliver to the party requesting payment, within twenty (20) business days after
receiving both the foregoing notice and all books, records and other information
reasonably requested by it, a detailed written statement ("Statement of
Objections") describing its objections (if any) thereto. The parties shall use
reasonable efforts to resolve any such objections, but if they do not obtain a
final resolution within twenty (20) business days (or any longer period mutually
agreed to by the parties) after the party requesting indemnification (or other
payment) has received the Statement of Objections, a Tax Settlement Auditor
(appointed


                                      118
<PAGE>   125

pursuant to Section 8.05(i) shall resolve any remaining objections.

              (i) Tax Settlement Auditor. If either party provides the other
party with a Statement of Objections with respect to any claim for
indemnification arising with respect to Taxes allocated to Sellers as provided
in Section 8.05(c) (other than with respect to Non-Filter Business Taxes), then
within ten (10) business days after receipt thereof, Buyer and Sellers shall
begin good faith negotiations to resolve such disagreement. If Buyer and Sellers
are able to resolve such disagreement within ten (10) business days after
receipt of the applicable Statement of Objections, the proposed claim for
indemnification shall be adjusted to reflect such resolution. If Buyer and
Seller are unable to resolve any disagreement concerning any claim for
indemnification pursuant to this Section 8.05 within ten (10) business days
after receipt of the applicable Statement of Objections, then Buyer and Sellers
shall jointly request an independent nationally recognized auditing firm
selected by the parties (the "Tax Settlement Auditor") to resolve any issue in
dispute as promptly as possible and shall cooperate with the Tax Settlement
Auditor to resolve such dispute. The fees and expenses of the Tax Settlement
Auditor shall be shared equally by Buyer and Sellers. The Tax Settlement Auditor
shall make a determination with respect to all disputed issues, which


                                      119
<PAGE>   126

determination shall be set forth in a written report delivered to Buyer and
Sellers. If the Tax Settlement Auditor determines that the amount of Taxes
payable by Sellers with respect to all disputed issues is less than the amount
set forth with respect to such items in the Statement of Objections, the fees
and expenses of the Tax Settlement Auditor shall be paid by Buyer; otherwise
such fees and expenses shall be paid by Sellers. Except as determined to the
contrary by the appropriate taxing authority upon an audit of Tax Returns filed
by or on behalf of Sellers or any of the Transferred Subsidiaries, Buyer and
Buyer's affiliates (including the Transferred Subsidiaries) shall file all
applicable Tax Returns consistent with the Tax Settlement Auditor's
determination.

              (j) Tax Related Adjustments. Seller and Buyer agree that any
indemnity payment made under this Agreement shall be made on an after-Tax basis
(which shall take into account any Tax benefit actually available to the
Indemnified Party as a result of the payment or accrual of the indemnified item)
and shall, to the extent permissible, be treated by the parties on their Tax
Returns as an adjustment to the Purchase Price.

         8.06 Tax Allocation.

              (a) The Final Purchase Price plus the U.S. dollar amount of the
Assumed Liabilities, shall be allocated to the assets purchased hereunder in
accordance with the rules of



                                      120
<PAGE>   127

Section 1060 of the Code and Treasury Regulations thereunder. Such allocation
shall be set forth on Schedule 8.06 and shall be used by each party in preparing
any filings required pursuant to Section 1060 or any similar provisions of
state, local or foreign law and all relevant income and franchise tax returns.
In the event of any adjustment to the Final Purchase Price pursuant to Article 2
of this Agreement, Buyer and Seller shall jointly make any appropriate
adjustments to Schedule 8.06 to reflect such adjustment under Article 2.

              (b) Buyer and Sellers agree that Buyer will make any election that
may be applicable under the provisions of Section 338 of the Code with respect
to any capital stock of any Foreign Subsidiary purchased under this Agreement.


              (c) With respect to the purchase of the stock of GS Cosa Mesa (and
the indirect purchase of the stock of Facet USA), to the extent permitted by
applicable law, Buyer may elect to treat such purchases as the purchase of such
corporation's assets pursuant to Section 338 (but not Section 338(h)(10)) of the
Code. If Buyer so elects, notwithstanding anything herein to the contrary, all
Taxes which become payable as a result of such election shall be allocated to
(and be the responsibility of) Buyer.

         8.07 Confidentiality. Each party hereto will hold and will cause its
directors, officers, employees, agents,



                                      121
<PAGE>   128

consultants and advisors to hold in strict confidence, unless compelled to
disclose by judicial or administrative process or, in the opinion of its
counsel, by other requirements of law, all documents and information concerning
the other party furnished to it by such other party or its representatives in
connection with the transactions contemplated by this Agreement (except to the
extent that such information can be shown to have been: (a) previously lawfully
known by the party to which it was furnished, (b) in the public domain through
no fault of such party, or (c) later lawfully acquired from other sources by the
party to which it was furnished), and each party will not release or disclose
such information to any other person, except its auditors, attorneys, financial
advisors, bankers and other consultants and advisors in connection with this
Agreement. If the transactions contemplated by this Agreement are not
consummated, such confidence shall be maintained except to the extent such
information comes into the public domain through no fault of the party required
to hold it in confidence, and in any event such information shall not be used to
the detriment of, or in relation to any investment in, the other party and all
such documents (including copies thereof and software) shall be returned to the
other party immediately upon the written request of such other party.

         8.08 Cooperation Regarding Defined Benefit Plan Administration. Buyer
agrees to cooperate with Sellers and to cause each of the Transferred
Subsidiaries to cooperate with Sellers in connection with Mark IV's
administration as Sellers may reasonably request, after the Closing Date, of its
master defined benefit plan as applicable to Filter Participants.

         8.09 Disposition of 401(k) Plan Assets.

              (a) Certain employees of Sellers that are engaged in the Filter
Business and certain employees of the Transferred Subsidiaries have accumulated
funds for their retirement in an account which is maintained for the benefit of
such employees under the terms of the Mark IV Savings & Retirement Plan, a
master 401(k) plan maintained by Mark IV for certain of its employees (the
"Master 401(k) Plan"). For purposes of this Agreement, such employees are
referred to as 401(k) Filter Participants.

              (b) As soon as practicable following the Closing, Mark IV shall
take such action as may reasonably be necessary to amend the Master 401(k) Plan
to provide that each Transferred Subsidiary employee who is a participant in the
Master 401(k) Plan shall have a one hundred percent (100%) vested interest in
his accrued benefit, if any, determined as of the Closing Date under the terms
of the Master 401(k) Plan.

<PAGE>   130

              (c) As soon as practicable after the Closing Date, Mark IV shall
take such actions as may be necessary to permit distributions to 401(k) Filter
Participants of the full amount of their respective accrued benefits in the Mark
IV Savings & Retirement Plan as of the valuation date as provided in such plan
and to permit the rollover of such distributions, including outstanding loans,
to Buyers' 401(k) plan. The distributions to be made by Mark IV pursuant to this
section shall be made pursuant to the provisions of such plan and applicable
laws and Mark IV and Buyer shall cooperate with each other and make all
appropriate W-2 or other filings required under the Code and ERISA in connection
with such distributions.

         8.10 Public Announcements. Buyer and Mark IV will consult with each
other before issuing any press releases or otherwise making any public

hereby and shall not issue any press release or make any public statement
without the consent of the remaining party, except as may be required by law.

         8.11 Employee Bonuses Due on Sale. Sellers agree to pay any bonuses
that may be due to any employee of the Filter Business as a result of the

         8.12 Transfer Taxes and Expenses.

              (a) Sellers shall bear and be responsible for all sales, use,
transfer, real property transfer or gain, VAT, recording or other similar
domestic or foreign taxes and fees ("Transfer Taxes") arising out of or in
connection with the transfer of any of the Assets and the transactions effected
pursuant to this Agreement to the extent such Transfer Taxes are (i) customarily
imposed on the seller in the jurisdiction in which such assets are located or
(ii) imposed as a result of the transactions contemplated in Section 6.08.

              (b) Buyer shall bear and be responsible for all Transfer Taxes

prompt advance notice (but in no event less than twenty (20) business days
advance notice) of any proposed action to be taken to control, remediate or
otherwise



                                      125
<PAGE>   132

respond to any violation of Environmental Laws giving rise to Damages (as
hereinafter defined) against which Buyer or any of Buyer's affiliates is
entitled to be defended, indemnified or held harmless pursuant to
indemnification for the Excluded Liabilities set forth in Section 1.05(g) of
this Agreement, provided that in the event that Sellers or any applicable
affiliate of Sellers is compelled by a governmental entity to control, remediate
or otherwise respond to such violation within a time period shorter than such
notice period, notice shall be provided to Buyer as soon as reasonably
practicable under such circumstances. Buyer shall cooperate with Sellers in
providing reasonable access, personnel and any other reasonably required action
to permit such control or remediation of environmental matters to be undertaken
and completed. If Buyer shall determine that the proposed action is not
appropriate and Buyer, on the one hand, and Sellers or the applicable affiliate
of Sellers, on the other, are not able to agree on the appropriate action to be
taken, the parties will submit the dispute to a mutually acceptable
environmental expert, whose determination shall be final and binding on the
parties. For purposes of determining the amount of any Damages and for purposes
of determining which actions should be undertaken to control, remediate or
otherwise respond to any violation of any Environmental Laws, the parties agree
that the action to be



                                      126
<PAGE>   133

<PAGE>   144

              (f) Notwithstanding anything to the contrary contained in this

         11.05 Conditions of Indemnification. The obligations and liabilities of
Sellers under Section 11.03 hereof and the obligations and liabilities of Buyer
under Section 11.04 hereof with respect to Claims relating to third parties
shall be subject to the following terms and conditions:

              (a) A party seeking indemnification under this Agreement
("Indemnified Party") will give the party required to provide such
indemnification (the "Indemnifying Party") prompt notice of any such Claim, and
thereafter, provided that the Indemnifying Party acknowledges in writing to the
Indemnified Party that the Indemnifying Party is obligated to indemnify the
Indemnified Party against such Claim, the Indemnifying Party will be permitted
to undertake the defense thereof by representatives chosen by it. The failure of
the Indemnified Party to provide any such notice shall not excuse the
Indemnifying Party from its obligations hereunder, provided



                                      138
<PAGE>   145

that, the amount of the Damages which the Indemnified Party shall be entitled to
be indemnified against shall be reduced by any Damages incurred by the
Indemnifying Party as a result of the Indemnified Party's failure to provide
notice.

              (b) If the Indemnifying Party, within a reasonable time after
notice of any such Claim (not to exceed thirty (30) days), fails to acknowledge
in writing its obligation to indemnify the Indemnified Party with respect to
such Claim or fails to diligently prosecute or settle such Claim, the
Indemnified Party will have the right to undertake the defense, compromise or
settlement of such Claim on behalf of and for the account and risk of the
Indemnifying Party, subject to the right of the Indemnifying Party to
participate at its expense in the defense of such Claim at any time prior to
settlement, compromise or final determination thereof.

              (c) Anything in this Section 11.05 to the contrary
notwithstanding: (i) if there is a reasonable probability that a Claim may
materially and adversely affect an Indemnified Party other than as a result of
money damages or other money payments, the Indemnified Party shall have the
right, at its own cost and expense, to defend, and with the consent of the
Indemnifying Party, to compromise or settle such Claim; and (ii) the
Indemnifying Party shall not, without the written consent of the Indemnified
Party, its successors and assigns, settle or





                                      139
<PAGE>   146

compromise any Claim or consent to the entry of any judgment which does not
include as an unconditional term thereof the giving by the claimant or the
plaintiff to the Indemnified Party, of a release from all liability in respect
of such Claim.

         11.06 Termination of Indemnification Obligations.

              (a) The obligations to indemnify and hold harmless a party hereto:
(i) contained in Sections 11.03(f) or 11.03(g) and Section 11.04(c) shall
terminate when the applicable representation or warranty terminates pursuant to
Section 11.01; and (ii) contained in the provisions of Sections 11.03(a) through
and including 11.03(e) or Sections 11.04(a) and (b) shall not terminate;
provided that, as to clause (i) above, such obligations to indemnify and hold
harmless shall not terminate with respect to any representation or warranty with
respect to which the Indemnified Party shall have, prior to the termination of
such representation or warranty, made a specific Claim relating to a breach of
such representation or warranty by delivering written notice (stating in
reasonable detail the basis of such Claim) to the Indemnifying Party.

              (b) Buyer shall have no right to be indemnified against any breach
of a representation or warranty made by Sellers pursuant to this Agreement to
the extent that, on the Closing Date, Buyer had knowledge that, as of the
Closing Date, there was a material breach, violation or inaccuracy in such



                                      140
<PAGE>   147

representation or warranty as made by Seller pursuant to Article 4 hereof, the
existence of which material breach, violation or inaccuracy is not disclosed in
writing by Buyer to Sellers on or prior to the Closing Date.

         11.07 Litigation Cooperation.

              (a) The Sellers shall cooperate with the Buyer and each of the
Transferred Subsidiaries and shall cause their respective officers, employees,
agents, auditors and representatives to cooperate with the Buyer and each of the
Transferred Subsidiaries in connection with the investigation, prosecution,
defense and settlement of any judicial or administrative proceeding or claim
which Buyer or any of the Transferred Subsidiaries has undertaken the defense of
in connection with the Buyer's obligation to indemnify the Sellers as provided
for in Section 11.04 above; provided that the Buyer shall reimburse the Sellers
and its officers, employees, agents, auditors and representatives for the
reasonable out-of-pocket costs and expenses incurred in providing such
assistance.

              (b) The Buyer shall cooperate with the Sellers and shall cause its
officers, employees, agents, auditors and representatives to cooperate with the
Sellers in connection with the investigation, prosecution, defense and
settlement of any judicial or administrative proceeding or claim which Sellers
have undertaken the defense of in connection with the obligation



                                      141
<PAGE>   148
of Sellers to indemnify the Buyer as provided for in Section 11.03 above;
provided that the Sellers shall reimburse the Buyer and its officers, employees,
agents, auditors and representatives for the reasonable out-of-pocket costs and
expenses incurred in providing such assistance.

         11.08 Environmental Claim. Sellers acknowledge that their indemnity
obligation for Excluded Liabilities covered by Section 1.05(g) shall include all
costs to correct any waste handling, waste storage or wastewater treatment
equipment that, as of the Closing Date, is a continuing source of release of
Regulated Materials to the environment, and that Buyer shall not be liable for
any additional release of Regulated Materials on or after the Closing Date to
the extent that such additional release is attributable to defects in such
equipment or facilities existing on the Closing Date.

         11.09 Remedies Cumulative. Except as herein expressly provided, the
remedies provided herein shall be cumulative and shall not preclude assertion by
any party hereto of any other rights or the seeking of any other remedies
against any other party hereto.

                                CREDIT AGREEMENT

To each of the Banks party hereto:

         The undersigned, CLARCOR Inc., a Delaware corporation (the "Borrower"),
applies to you for your several commitments, subject to all the terms and
conditions hereof and on the basis of the representations and warranties
hereinafter set forth, to make available a revolving credit for loans and
letters of credit (the "Revolving Credit") and a swing line credit (the "Swing
Line") as described herein. Each of you is hereinafter referred to individually
as a "Bank," all of you are hereinafter referred to collectively as the "Banks,"
and Firstar Bank Milwaukee, National Association in its capacity as agent for
the Banks hereunder is hereinafter referred to as the "Agent" and Bank One,
Illinois, NA and Amcore Bank N.A., in their capacity as co-agents for the Banks
are hereinafter referred to individually as a "Co-Agent" and collectively as the
"Co-Agents."

         1.       The Committed Facility.

                  1.1. The Revolving Credit Commitments. Subject to the terms
and conditions hereof, each Bank, by its acceptance hereof, severally agrees to
make a loan or loans (individually a "Committed Revolving Loan" and collectively
"Committed Revolving Loans") to the Borrower from time to time on a revolving
basis in U.S. Dollars and Alternative Currencies in an aggregate outstanding
Original Dollar Amount up to the amount of its revolving credit commitment set
forth on the applicable signature page hereof (its "Revolving Credit Commitment
and, cumulatively for all the Banks, the "Revolving Credit Commitments"),
subject to any reductions thereof pursuant to the terms hereof, before the
Revolving Credit Termination Date. The sum of the aggregate Original Dollar
Amount of all Loans (whether Committed Revolving Loans or Swing Loans) and of
L/C Obligations at any time outstanding shall not exceed the Revolving Credit
Commitments in effect at such time. Each Borrowing of Committed Revolving Loans
shall be made ratably from the Banks in proportion to their respective
Percentages. As provided in Section 1.5(a) hereof, the Borrower may elect that
each Borrowing of Committed Revolving Loans denominated in U.S. Dollars be
either Domestic Rate Loans or Eurocurrency Loans. All Loans denominated in an
Alternative Currency shall be Eurocurrency Loans. Committed Revolving Loans may
be repaid and the principal amount thereof reborrowed before the Revolving
Credit Termination Date, subject to all the terms and conditions hereof. On the
Revolving Credit Termination Date, the principal amount of, and all accrued and
unpaid interest on,




<PAGE>   9


the Loans and L/C Obligations, and all other amounts owed by the Borrower
hereunder and under the other Credit Documents shall be immediately due and
payable.

         1.2.    Letters of Credit.

                  (a) General Terms. Subject to the terms and conditions hereof,
as part of the credit available under the Revolving Credit Commitments, the
Issuing Bank shall issue standby or commercial letters of credit (each a "Letter
of Credit") for the Borrower's account in U.S. Dollars in an aggregate undrawn
face amount up to the amount of the L/C Limit, provided that the aggregate L/C
Obligations at any time outstanding shall not exceed the difference between the
Revolving Credit Commitments in effect at such time and the aggregate Original
Dollar Amount of all Loans (whether Committed Revolving Loans or Swing Loans)
then outstanding. Each Letter of Credit shall be issued by the Issuing Bank, but
each Bank shall be obligated to reimburse the Issuing Bank for such Bank's
Percentage of the amount of each drawing thereunder and, accordingly, the
undrawn face amount of each Letter of Credit shall constitute usage of the
Revolving Credit Commitment of each Bank pro rata in accordance with each Bank's
Percentage.

                  (b) Applications. At any time before the Revolving Credit
Termination Date, the Issuing Bank shall, at the request of the Borrower, issue
one or more Letters of Credit, in a form satisfactory to the Issuing Bank, with
expiration dates no later than the earlier of (i) twelve (12) calendar months
from the date of issuance (or be cancelable not later than twelve (12) calendar
months from the date of issuance or renewal) or (ii) the Revolving Credit
Termination Date, in an aggregate face amount as set forth above, upon the
receipt of a duly executed application for the relevant Letter of Credit in the
form customarily prescribed by the Issuing Bank for the type of Letter of
Credit, whether standby or commercial, requested (each an "Application"). The
current forms of the Issuing Bank's Applications are attached as Schedule 1.2
(Standby) and Schedule 1.2 (Commercial) hereto. The Issuing Bank shall provide
the Borrower and each Bank with copies of any new form of Application that may,
from time to time, be adopted by the Issuing Bank. Notwithstanding anything
contained in any Application to the contrary: (i) the Borrower's obligation to
pay fees in connection with each Letter of Credit shall be as exclusively set
forth in Section 4.1(b) hereof, (ii) before the occurrence of a Default or an
Event of Default, the Issuing Bank will not call for the funding by the Borrower
of any amount under a Letter of Credit, or any other form of collateral security
for the Borrower's obligations in connection with such Letter of Credit, before
being presented with a drawing thereunder, (iii) if the Issuing Bank is not
timely reimbursed for the amount of any



                                       2
<PAGE>   10


drawing under a Letter of Credit on the date such drawing is paid, the
Borrower's obligation to reimburse the Issuing Bank for the amount of such
drawing shall bear interest (which the Borrower hereby promises to pay) from and
after the date such drawing is paid at a rate per annum equal to the sum of 2%
plus the Applicable Margin for Domestic Rate Loans plus the Domestic Rate from
time to time in effect and (iv) if there is any inconsistency between the terms
of an Application and the terms of this Agreement, this Agreement shall govern.
The Issuing Bank will promptly notify the Banks of each issuance by it of a
Letter of Credit. If the Issuing Bank issues any Letters of Credit with
expiration dates that are automatically extended unless the Issuing Bank gives
notice that the expiration date will not so extend beyond its then scheduled
expiration date, the Issuing Bank will give such notice of nonrenewal before the
time necessary to prevent such automatic extension if before such required
notice date: (i) the expiration date of such Letter of Credit if so extended
would be after the Revolving Credit Termination Date, (ii) the Revolving Credit
Commitments have been terminated or (iii) an Event of Default exists and the
Required Banks have given the Issuing Bank instructions not to so permit the
extension of the expiration date of such Letter of Credit. The Issuing Bank
agrees to issue amendments to the Letter(s) of Credit increasing the amount, or
extending the expiration date, thereof at the request of the Borrower subject to
the conditions of Section 8 and the other terms of this Section 1.2.

                  (c) The Reimbursement Obligations. The Issuing Bank shall
notify the Borrower of each drawing under a Letter of Credit. Subject to Section
1.2(b) hereof, the obligation of the Borrower to reimburse the Issuing Bank for
all drawings under a Letter of Credit (a "Reimbursement Obligation") shall be
governed by the Application related to such Letter of Credit, except that (i)
reimbursement of each drawing shall be made in immediately available funds at
the Issuing Bank's principal office in Milwaukee, Wisconsin by no later than
Noon (Milwaukee time) on the date when such drawing is paid (the "Honor Date")
and (ii) if the Borrower fails to reimburse the Issuing Bank for the full amount
of a drawing under a Letter of Credit by Noon (Milwaukee time) on the Honor
Date, [x] the Borrower shall, unless the Revolving Credit Commitments have
terminated, be deemed to have requested Committed Revolving Loans consisting of
Domestic Rate Loans from the Banks in the aggregate amount equal to the
unreimbursed amount of such drawing and [y] the Issuing Bank shall, by 1:30 p.m.
(Milwaukee time) on the Honor Date, notify the Agent and each Bank of the
aggregate amount of the Committed Revolving Loans to be made on such date. In
the event of such a Borrowing, each Bank shall fund its Percentage of such
Committed Revolving Loans in the manner specified in Section 1.5(d) by 3:00 p.m.
(Milwaukee time) on the Honor Date and the Agent shall forward such Committed
Revolving Loans to the Issuing Bank for credit against the Borrower's
Reimbursement Obligation. If




                                       3
<PAGE>   11


the Borrower does not pay in full such Reimbursement Obligation on the Honor
Date (whether by payment by the Borrower or with the proceeds of Committed
Revolving Loans) and the Participating Banks fund their participations therein
in the manner set forth in Section 1.2(d) below, then all payments thereafter
received by the Issuing Bank in discharge of any of the relevant Reimbursement
Obligations shall be distributed in accordance with Section 1.2(d) below.

                  (d) The Participating Interests. Each Bank (other than the
Bank then acting as Issuing Bank in issuing Letters of Credit), by its
acceptance hereof, severally agrees to purchase from the Issuing Bank, and the
Issuing Bank hereby agrees to sell to each such Bank (a "Participating Bank"),
an undivided percentage participating interest (a "Participating Interest"), to
the extent of its Percentage, in each Letter of Credit issued by, and each
Reimbursement Obligation owed to, the Issuing Bank. Upon any failure by the
Borrower to pay any Reimbursement Obligation by Noon (Milwaukee time) on the
Honor Date as set forth in Section 1.2(c) above, the Issuing Bank will promptly
notify each Bank, specifying the Letter of Credit drawn upon and the amount
which has not been reimbursed by the Borrower. In the event that such
Reimbursement Obligation is not paid with the proceeds of Committed Revolving
Loans as set forth in Section 1.2(c) above or if the Issuing Bank is required at
any time to return to the Borrower or to a trustee, receiver, liquidator,
custodian or other Person any portion of any payment of any Reimbursement
Obligation, each Participating Bank shall, not later than the Business Day it
receives a certificate in the form of Exhibit C hereto from the Issuing Bank to
such effect, if such certificate is received before 1 p.m. (Milwaukee time), or
not later than the following Business Day, if such certificate is received after
such time, pay to the Issuing Bank an amount equal to its Percentage of such
unpaid or recaptured Reimbursement Obligation together with interest on such
amount accrued from the date the related payment was made by the Issuing Bank to
the date of such payment by such Participating Bank at a rate per annum equal
to: (i) from the date the related payment was made by the Issuing Bank to the
date two Business Days after payment by such Participating Bank is due
hereunder, the Federal Funds Rate for each such day and (ii) from the date two
Business Days after the date such payment is due from such Participating Bank to
the date such payment is made by such Participating Bank, the Domestic Rate in
effect for each such day. Each such Participating Bank shall thereafter be
entitled to receive its Percentage of each payment received in respect of the
relevant Reimbursement Obligation and of interest paid thereon, with the Issuing
Bank retaining its Percentage as a Bank hereunder.

                  The several obligations of the Participating Banks to the
Issuing Bank under this Section 1.2(d) shall be absolute, irrevocable and
unconditional under any and all circumstances whatsoever and shall not be
subject




                                       4
<PAGE>   12


to any set-off, counterclaim or defense to payment which any Participating Bank
may have or have had against the Borrower, the Issuing Bank, any other Bank or
any other Person whatsoever. Without limiting the generality of the foregoing,
such obligations shall not be affected by any Default or Event of Default or by
any reduction or termination of any Commitment of any Bank, and each payment by
a Participating Bank under this Section 1.2(d) shall be made without any offset,
abatement, withholding or reduction whatsoever. The Issuing Bank shall be
entitled to offset amounts received for the account of a Bank under this
Agreement against unpaid amounts due from such Bank to the Issuing Bank
hereunder (whether as fundings of participations, indemnities or otherwise), but
shall not be entitled to offset against amounts owed to the Issuing Bank by any
Bank arising outside this Agreement.

                  (e) Indemnification. The Participating Banks shall, to the
extent of their respective Percentages, indemnify the Issuing Bank (to the
extent not reimbursed by the Borrower) against any cost, expense (including
reasonable counsel fees and disbursements), claim, demand, action, loss or
liability (except such as result from the Issuing Bank's gross negligence or
willful misconduct) that the Issuing Bank may suffer or incur in connection with
any Letter of Credit. The obligations of the Participating Banks under this
Section 1.2(e) and all other parts of this Section 1.2 shall survive termination
of this Agreement and of all other L/C Documents.

         1.3.     Applicable Interest Rates.

                  (a) Domestic Rate Loans. The aggregate principal amount of
Domestic Rate Loans outstanding from time to time shall bear interest (computed
on the basis of a year of 365 or 366 days, as applicable, and actual days
elapsed) prior to maturity (whether by acceleration or otherwise) at a rate per
annum equal to the sum of the Applicable Margin for Domestic Rate Loans plus the
Domestic Rate from time to time in effect, payable on the last Business Day of
each calendar quarter and at maturity (whether by acceleration or otherwise).

                      "Domestic Rate" means for any day the greater of:

                      (i)    the rate of interest announced by the Agent from
time to time as its prime rate, or equivalent, as in effect on such day, with
any change in the Domestic Rate resulting from a change in said prime rate to be
effective as of the date of the relevant change in said prime rate; and

                      (ii)   the sum of (x) the rate determined by the Agent to
be the prevailing rate per annum (rounded upwards, if not a multiple of 1/16th



                                       5
<PAGE>   13


of 1%, to the next higher 1/100 of 1%) at approximately 10:00 a.m. (Milwaukee
time) (or as soon thereafter as is practicable) on such day (or, if such day is
not a Business Day, on the immediately preceding Business Day) for the purchase
at face value of overnight Federal funds in an amount comparable to the
principal amount owed to the Agent for which such rate is being determined, plus
(y) 1/2 of 1% (0.50%).

                  (b) Eurocurrency Loans. Each Eurocurrency Loan made or
maintained by a Bank shall bear interest during each Interest Period it is
outstanding (computed on the basis of a year of 360 days and actual days
elapsed) on the unpaid principal amount thereof from the date such Loan is
advanced, continued, or created by conversion from a Domestic Rate Loan until
maturity (whether by acceleration or otherwise) at a rate per annum equal to the
sum of the Applicable Margin for Eurocurrency Loans plus the Adjusted LIBOR
applicable for such Interest Period, payable on the last day of the Interest
Period and at maturity (whether by acceleration or otherwise), and if the
applicable Interest Period is longer than three months, on each day occurring
every three months after the commencement of such Interest Period.

                  "Adjusted LIBOR" means a rate per annum determined in
accordance with the following formula:

                  Adjusted LIBOR =                 LIBOR
                                    -----------------------------------
                                    1 - Eurocurrency Reserve Percentage

                  "LIBOR" means, for any Interest Period: (a) the LIBOR Index
Rate for such Interest Period, if such rate is available, and (b) if the LIBOR
Index Rate cannot be determined, the arithmetic average of the rates of interest
per annum (rounded upwards, if not a multiple of 1/16th of 1%, to the nearest
1/100 of 1%) at which deposits in U.S. Dollars or the relevant Alternative
Currency, as appropriate, in immediately available funds are offered to the
Agent at 11 a.m. (London, England time) two Business Days before the beginning
of such Interest Period by three or more major banks in the interbank
eurocurrency market selected by the Agent for delivery on the first day of and
for a period equal to such Interest Period in an amount equal or comparable to
the principal amount of the Eurocurrency Loan scheduled to be made by the Agent
as part of such Borrowing.

                  "LIBOR Index Rate" means, for any Interest Period, the rate
per annum (rounded upwards, if necessary, to the next higher one
hundred-thousandth of a percentage point) for deposits in U.S. Dollars or the
relevant Alternative Currency, as appropriate, for a period equal to such
Interest Period, which appears on the Telerate Page 3740 or 3750, as appropriate
for such

currency, as of 11 a.m. (London, England time) on the day two Business Days
before the commencement of such Interest Period.

                  "Telerate Page 3740" or "3750" means the display designated as
"Page 3740" or "Page 3750," as appropriate, on the Telerate Service (or such

such other service as may be nominated by the British Bankers' Association as
the information vendor for the purpose of displaying British Bankers'
Association Interest Settlement Rates for U.S. Dollar, Pounds Sterling or Euros
(in the case of Telerate Page 3750) deposits).

                  "Eurocurrency Reserve Percentage" means, for any Borrowing of
a Eurocurrency Loan, the daily average for the applicable Interest Period of the
maximum rate, expressed as a decimal, at which reserves (including, without
limitation, any supplemental, marginal and emergency reserves) are imposed
during such Interest Period by the Board of Governors of the Federal Reserve
System (or any successor) on "eurocurrency liabilities", as defined in such
Board's Regulation D (or in respect of any other category of liabilities that
includes deposits by reference to which the interest rate on Eurocurrency Loans
is determined or any category of extensions of credit or other assets that
include loans by non-United States offices of any Bank to United States
residents), subject to any amendments of such reserve requirement by such Board
or its successor, taking into account any transitional adjustments thereto. For
purposes of this definition, the Eurocurrency Loans shall be deemed to be
"eurocurrency liabilities" as defined in Regulation D.

                  (c) Applicable Margin. With respect to Committed Revolving
Loans, the fees with respect to Standby Letters of Credit payable under section
4.2 hereof and the commitment fee payable under Section 4.1 hereof, the

Level II Status            0%                      .65%                .10%

provided, however, that all of the foregoing is subject to the following:

                        (i)   the initial Applicable Margin shall be the
Applicable Margin for Level IV Status and shall remain in effect through the
first Margin Determination Date occurring after November 30, 1999;

                        (ii)  on or before the date that is ten Business Days
after the latest date by which the Borrower is required to deliver a Compliance
Certificate to the Banks for a given accounting period pursuant to Section 9.6
hereof, the Agent shall determine whether Level I Status, Level II Status, Level
III Status, Level IV Status or Level V Status exists as of the close of the
applicable accounting period (each date that is ten Business Days after the
latest date by which the Borrower is required to deliver a Compliance
Certificate to the Banks being herein referred to as the "Margin Determination
Date") and shall also determine the Net Leverage Ratio as of such close, in each
case based upon such Compliance Certificate and the financial statements
delivered to the Banks under Section 9.6 hereof for such accounting period, and
shall promptly notify the Borrower and the Banks of such determination and of
any change in the Applicable Margin resulting therefrom;



                                       8
<PAGE>   16


                        (iii) subject to clause (i) above, any change in the
Applicable Margin shall be effective as of such Margin Determination Date, with
such new Applicable Margin to continue in effect until the next Margin
Determination Date. If the Borrower has not delivered a Compliance Certificate
by the date such Compliance Certificate is required to be delivered under
Section 9.6 hereof, until a Compliance Certificate is delivered before the next
Margin Determination Date, the Applicable Margin shall be the Applicable Margin
for Level V Status. If the Borrower subsequently delivers a Compliance
Certificate before the next Margin Determination Date, the Applicable Margin
established by such Compliance Certificate shall take effect from the date of
such delivery and remain effective until the next Margin Determination Date; and

                        (iv) if and so long as any Event of Default has occurred
and is continuing hereunder, notwithstanding anything herein to the contrary,
the Applicable Margin shall be the Applicable Margin for Level V Status.

                  (d) Alternative Currencies. On the date the Borrower requests
a Borrowing of Eurocurrency Loans in an Alternative Currency, as provided in
Section 1.5(a) below, the Agent shall promptly notify each Bank of the currency
in which such Borrowing is requested. If a Bank determines that such Alternative
Currency is not available to it in sufficient amount and for a sufficient term
to enable it to advance or continue the Loan requested of it as part of such
Eurocurrency Borrowing and so notifies the Agent no later than 2 p.m. (Milwaukee
time) on the same day it receives notice from the Agent of such requested Loan,
the Agent shall so notify the Borrower by 2:45 p.m. (Milwaukee time). If the
Borrower nevertheless desires such Borrowing, it must notify the Agent by no
later than 3 p.m. (Milwaukee time) on such day. If the Agent does not receive
such notice from the Borrower by 3 p.m. (Milwaukee time), the Borrower shall
automatically be deemed to have revoked its request for the Eurocurrency
Borrowing and the Agent will promptly notify the Banks of such revocation and
such Eurocurrency Borrowing shall not be made in whole or part. If the Borrower
does give such notice by 3 p.m. (Milwaukee time), each Bank that did not notify
the Agent by 2 p.m. (Milwaukee time) that the requested Alternative Currency is
unavailable to it to fund the requested Loan shall, subject to Section 8 hereof,
make its Loan in the requested Alternative Currency in accordance with Section
1.5(d) hereof. Each Bank that did so notify the Agent by 2 p.m. (Milwaukee time)
that it would not be able to make the Loan requested from it shall, subject to
Section 8 hereof, make a Eurocurrency Loan denominated in U.S. Dollars in the
Original Dollar Amount of, and with the same Interest Period as, the
Eurocurrency Loan such Bank was originally requested to make. Such Eurocurrency
Loan denominated in U.S. Dollars shall be made by the affected



                                       9
<PAGE>   17


Bank on the same day as the other Banks make their Eurocurrency Loans
denominated in the applicable Alternative Currency as part of the relevant
Borrowing of Eurocurrency Loans, but shall bear interest with reference to the
Adjusted LIBOR applicable to U.S. Dollars rather than the relevant Alternative
Currency for the applicable Interest Period and shall be made available in
accordance with the procedures for disbursing U.S. Dollar Loans under Section
1.5(d) hereof. Any Loan made in an Alternative Currency shall be advanced in
such currency, and, except as otherwise provided in Section 1.5(a), all payments
of principal and interest thereon shall be made in such Alternative Currency.

                  (e) Rate Determinations. The Agent shall determine each
interest rate applicable to Committed Revolving Loans and the Original Dollar
Amount of Loans denominated in Alternative Currencies, and a reasonable
determination thereof by the Agent shall be conclusive and binding except in the
case of demonstrable error or willful misconduct. The Original Dollar Amount of
each Eurocurrency Loan denominated in an Alternative Currency shall be
determined or redetermined, as applicable, effective as of the first day of each
Interest Period applicable to such Loan.

                  1.4. Minimum Borrowing Amounts. Each Borrowing of Domestic
Rate Loans shall be in an amount not less than $500,000 and in integral
multiples of $100,000. Each Borrowing of Eurocurrency Loans in U.S. Dollars
shall be in an amount not less than $5,000,000 and in integral multiples of
$1,000,000. Each Borrowing of Eurocurrency Loans in an Alternative Currency
shall be in an amount not less than an Original Dollar Amount of $10,000,000 and
in such integral multiple of 100,000 units of the relevant currency as would
have the Original Dollar Amount most closely approximating $1,000,000 or an
integral multiple thereof.

                  1.5. Manner of Borrowing Committed Revolving Loans and
Designating Interest Rates Applicable to Committed Revolving Loans.

                       (a) Notice to the Agent. In order to borrow any Committed
Revolving Loans, the Borrower shall give notice to the Agent by no later than 11
a.m. (Milwaukee time): (i) at least four Business Days before the date on which
the Borrower requests the Banks to advance a Borrowing of Eurocurrency Loans
denominated in an Alternative Currency, (ii) at least three Business Days before
the date on which the Borrower requests the Banks to advance a Borrowing of
Eurocurrency Loans denominated in U.S. Dollars and (iii) on the date the
Borrower requests the Banks to advance a Borrowing of Domestic Rate Loans. The
Loans included in each Borrowing shall bear interest




                                       10
<PAGE>   18


initially at the type of rate specified in such notice of a new Borrowing.
Thereafter, the Borrower may from time to time elect to change or continue the
type of interest rate borne by each Borrowing or, subject to Section 1.4's
minimum amount requirement for each outstanding Borrowing, a portion thereof, as
follows: (i) if such Borrowing is of Eurocurrency Loans, on the last day of the
Interest Period applicable thereto, the Borrower may continue part or all of
such Borrowing as Eurocurrency Loans for an Interest Period or Interest Periods
specified by the Borrower or, if such Eurocurrency Loan is denominated in U.S.
Dollars, convert part or all of such Borrowing into Domestic Rate Loans, (ii) if
such Borrowing is of Domestic Rate Loans, on any Business Day, the Borrower may
convert all or part of such Borrowing into Eurocurrency Loans denominated in
U.S. Dollars for an Interest Period or Interest Periods specified by the
Borrower. The Borrower shall give all such notices requesting the advance,
continuation, or conversion of a Borrowing to the Agent by telephone or telecopy
(which notice shall be irrevocable once given and, if by telephone, shall be
promptly confirmed in writing). Notices of the continuation of a Borrowing of
Eurocurrency Loans denominated in U.S. Dollars for an additional Interest Period
or of the conversion of part or all of a Borrowing of Eurocurrency Loans
denominated in U.S. Dollars into Domestic Rate Loans or of Domestic Rate Loans
into Eurocurrency Loans must be given by no later than 11 a.m. (Milwaukee time)
at least three Business Days before the date of the requested continuation or
conversion. Notices of the continuation of a Borrowing of Eurocurrency Loans
denominated in an Alternative Currency must be given no later than 11 a.m.
(Milwaukee time) at least four Business Days before the requested continuation.
All such notices concerning the advance, continuation, or conversion of a
Borrowing shall specify the date of the requested advance, continuation or
conversion of a Borrowing (which shall be a Business Day), the amount of the
requested Borrowing to be advanced, continued, or converted, the type of
Committed Revolving Loans to comprise such new, continued or converted Borrowing
and, if such Borrowing is to be comprised of Eurocurrency Loans, the currency
and Interest Period applicable thereto. The Borrower agrees that the Agent may
rely on any such telephonic or telecopy notice given by any person it in good
faith believes is an Authorized Representative without the necessity of
independent investigation, and in the event any such notice by telephone
conflicts with any written confirmation, such telephonic notice shall govern if
the Agent has acted in reliance thereon. Notwithstanding the foregoing, no more
than 10 Borrowings comprised of Eurocurrency Loans may be outstanding at any
time and, unless the Required Banks otherwise agree, no Loans may be made or
continued as, or converted into, Eurocurrency Loans if a Default or Event of
Default exists. If a Default or Event of Default exists on the last day of an
Interest Period but the Notes have not been declared to be or become due and
payable under Sections 10.02 and 10.03, such Eurocurrency Loans shall
automatically be converted to Domestic Rate Loans in a principal amount equal to



                                       11
<PAGE>   19


(x) if such Eurocurrency Loans are denominated in U.S. Dollars, such amount and
(y) if such Eurocurrency Loans are denominated in an Alternative Currency, an
amount equal to the U.S. Dollar Equivalent of the principal amount of such
Eurocurrency Loans.

                  (b) Notice to the Banks. The Agent shall give prompt
telephonic or telecopy notice to each Bank of any notice from the Borrower
received pursuant to Section 1.5.(a) above. The Agent shall give notice to the
Borrower and each Bank by like means of the interest rate applicable to each
Borrowing of Eurocurrency Loans and, if such Borrowing is denominated in an
Alternative Currency, shall give notice by such means to the Borrower and each
Bank of the Original Dollar Amount thereof.

                  (c) Borrower's Failure to Notify. If the Borrower fails to
give notice pursuant to Section 1.5(a) above of the continuation or conversion
of any outstanding principal amount of a Borrowing of Eurocurrency Loans
denominated in U.S. Dollars before the last day of its then current Interest
Period within the period required by Section 1.5(a) and has not notified the
Agent within the period required by Section 3.3 that it intends to prepay such
Borrowing, such Borrowing shall automatically be converted into a Borrowing of
Domestic Rate Loans. If the Borrower fails to give notice pursuant to Section
1.5(a) above of the continuation of any outstanding principal amount of a
Borrowing of Eurocurrency Loans denominated in an Alternative Currency before
the last day of its then current Interest Period within the period required by
Section 1.5(a) and has not notified the Agent within the period required by
Section 3.3 that it intends to prepay such Borrowing, such Borrowing shall
automatically be continued as a Borrowing of Eurocurrency Loans in the same
Alternative Currency with an Interest Period of one month, subject to the
application of Section 1.4, the restrictions contained in the definition of
Interest Period and the restrictions in the last sentence of Section 1.5(a)
hereof.

                  (d) Disbursement of Committed Revolving Loans. Not later than
Noon (Milwaukee time) on the date of any requested advance of new Borrowings,
subject to Section 8 hereof, each Bank shall make available its Committed
Revolving Loan comprising part of such Borrowing in funds immediately available
at the principal office of the Agent in Milwaukee, Wisconsin, except that if
such Borrowing is denominated in an Alternative Currency each Bank shall,
subject to Section 1.3(d) and Section 8, make available its Committed Revolving
Loan comprising part of such Borrowing at such office as the Agent has
previously specified in a notice to each Bank, in such funds as are then
customary for the settlement of international transactions in such currency and
no later than such local time as is necessary for such funds to be received and




                                       12
<PAGE>   20


transferred to the Borrower for same day value on the date of the Borrowing. The
Agent shall make available to the Borrower Committed Revolving Loans denominated
in U.S. Dollars at the Agent's principal office in Milwaukee, Wisconsin and
Committed Revolving Loans denominated in Alternative Currencies at such office
as the Agent has previously agreed to with the Borrower, in each case in the
type of funds received by the Agent from the Banks.

                  (e) Agent Reliance on Bank Funding. Unless the Agent shall
have been notified by a Bank prior to (or, in the case of a Borrowing of
Domestic Rate Loans, by 1 p.m. (Milwaukee time) on) the date on which such Bank
is scheduled to make payment to the Agent of the proceeds of a Loan (which
notice shall be effective upon receipt) that such Bank does not intend to make
such payment, the Agent may assume that such Bank has made such payment when due
and the Agent may in reliance upon such assumption (but shall not be required
to) make available to the Borrower the proceeds of the Loan to be made by such
Bank and, if any Bank has not in fact made such payment to the Agent, such Bank
shall, on demand, pay to the Agent the amount made available to the Borrower
attributable to such Bank together with interest thereon in respect of each day
during the period commencing on the date such amount was made available to the
Borrower and ending on (but excluding) the date such Bank pays such amount to
the Agent at a rate per annum equal to the Federal Funds Rate or, in the case of
a Loan denominated in an Alternative Currency, the cost to the Agent of funding
the amount it advanced to fund such Bank's Loan, as determined by the Agent. If
such amount is not received from such Bank by the Agent immediately upon demand,
the Borrower will, on demand, repay to the Agent the proceeds of the Loan
attributable to such Bank with interest on any amount unpaid more than three
Business Days after such demand (but otherwise without interest) at a rate per
annum equal to the interest rate applicable to the relevant Loan, but without
such payment being considered a payment or prepayment of a Loan under Section
3.6 hereof, so that the Borrower will have no liability under such section with
respect to such payment.

         2.       The Swing Line.

                  2.1. Swing Loans. Subject to all of the terms and conditions
hereof, Firstar Bank Milwaukee, National Association ("Firstar") agrees to make
loans in U.S. Dollars to the Borrower under the Swing Line ("Swing Loans") which
shall not in the aggregate at any time outstanding exceed the lesser of: (i) the
Swing Line Commitment or (ii) the difference between the Revolving Credit
Commitments in effect at such time and the Original Dollar Amount of all Loans
and L/C Obligations outstanding at the time of computation. The Swing Line
Commitment shall be available to the Borrower and may be availed of by the



                                       13
<PAGE>   21



Borrower from time to time and borrowings thereunder may be repaid and used
again during the period ending on the Revolving Credit Termination Date. Without
regard to the face principal amount of the Swing Line Note, the actual principal
amount at any time outstanding and owing by the Borrower on account of the Swing
Line Note during the period ending on the Revolving Credit Termination Date
shall be the sum of all Swing Loans then or theretofore made thereon less all
principal payments actually received thereon during such period.

                  2.2. Interest on Swing Loans. The aggregate outstanding
principal balance of Swing Loans outstanding shall bear interest at the Firstar
Quoted Rate in effect from time to time, provided that if the Swing Loans are
not paid when due (whether by lapse of time, acceleration or otherwise) the
Swing Loans shall bear interest, whether before or after judgment, until payment
in full thereof at a rate per annum equal to the sum of 2% plus the Domestic
Rate from time to time in effect plus the Applicable Margin for Domestic Rate
Loans. Interest on Swing Loans outstanding from time to time shall be due and
payable on the last Business Day of each month, and interest after maturity
(whether by lapse of time, acceleration or otherwise) shall be due and payable
upon demand. Firstar shall provide written notice to the Borrower of the Firstar
Quoted Rate in effect from time to time and any change in the Firstar Quoted
Rate shall be effective on the Business Day following the date Firstar provides
notice thereof.

                  2.3. Requests for Swing Loans. The Borrower shall give Firstar
prior notice (which may be written or oral) no later than Noon (Milwaukee time)
on the date upon which the Borrower requests that any Swing Loan be made, of the
amount and date of such Swing. Subject to all of the terms and conditions
hereof, the proceeds of such Swing Loan shall be made available to the Borrower
on the date so requested at the offices of the Agent in Milwaukee, Wisconsin.
Anything contained in the foregoing to the contrary notwithstanding: (i) the
obligation of Firstar to make Swing Loans shall be subject to all of the terms
and conditions of this Agreement and (ii) Firstar shall not be obligated to make
more than one Swing Loan during any one day.

                  2.4. Conversion of Swing Line Loans into Revolving Credit
Loans. Upon the occurrence of an Event of Default or at any time upon the
request of Firstar: (i) payments which pursuant to Section 5 hereof are to be
allocated to the principal of the Revolving Credit Notes and the Swing Line Note
shall first be applied to the Swing Line Note until the Swing Line Note is
repaid in full and (ii) either [a] each Bank shall make a Committed Revolving
Loan in an amount equal to its Percentage of the outstanding principal balance
of the Swing Line Note plus accrued interest thereon (and the Agent shall apply
such Revolving Credit Loans in repayment of the Swing Line Note) or [b] each
Bank shall



                                       14
<PAGE>   22


purchase from Firstar a participation in the amount equal to such Bank's
Percentage applicable to Committed Revolving Loans of the outstanding principal
balance of and accrued interest on the Swing Line Note. All of the foregoing
principles shall be applied as though the Revolving Credit Commitments and the
Swing Line Commitment had not terminated pursuant to Section 10.2 or 10.3
hereof, whether or not such is in fact the case.

         3.       General Provisions Applicable to all Loans.

                  3.1. Interest Periods. As provided in Section 1.5(a) hereof in
the case of Committed Revolving Loans, at the time of each request to advance,
continue or create by conversion Eurocurrency Loans hereunder the Borrower shall
select an Interest Period applicable to such Eurocurrency Loans from among the
available options. The term "Interest Period" means the period commencing on the
date a Borrowing of Eurocurrency Loans is advanced, continued or created by
conversion and ending one, two, three or six months thereafter, provided,
however, that:

                  (i)   the Borrower may not select an Interest Period that
extends beyond the Revolving Credit Termination Date;

                  (ii)  whenever the last day of any Interest Period would
otherwise be a day that is not a Business Day, the last day of such Interest
Period shall be extended to the next succeeding Business Day, provided that if
such extension would cause the last day of an Interest Period to occur in the
following calendar month, the last day of such Interest Period shall be the
immediately preceding Business Day; and

                  (iii) for purposes of determining an Interest Period, a month
means a period starting on one day in a calendar month and ending on the
numerically corresponding day in the next calendar month; provided, however,
that if there is no numerically corresponding day in the month in which such an
Interest Period is to end or if such an Interest Period begins on the last
Business Day of a calendar month, then such Interest Period shall end on the
last Business Day of the calendar month in which such Interest Period is to end.

                  3.2. Maturity of Loans. Each Committed Revolving Loan shall
mature and become due and payable by the Borrower on the last day of the
Interest Period applicable thereto (unless converted or continued in accordance
with the terms of this Agreement) or, in any event, on the Revolving Credit
Termination Date. Swing Loans shall mature and become payable by the Borrower on
the Revolving Credit Termination Date.

         3.3.     Prepayments.

                  (a) Committed Revolving Loans. The Borrower may prepay,
without premium or penalty but subject to Section 3.6, in whole or in part (but,
if in part, then: (i) if such Borrowing is of Domestic Rate Loans, in an amount
not less than $500,000, (ii) if such Borrowing is of Eurocurrency Loans
denominated in U.S. Dollars, in an amount not less than $1,000,000, (iii) if
such Borrowing is denominated in an Alternative Currency, an amount for which
the U.S. Dollar Equivalent is not less than $1,000,000 and (iv) in an amount
such that the minimum amount required for a Borrowing of Committed Revolving
Loans pursuant to Section 1.4 hereof remains outstanding, any Borrowing of
Eurocurrency Loans, upon three Business Days' prior notice to the Agent or, in
the case of a Borrowing of Domestic Rate Loans, notice delivered to the Agent no
later than 11 a.m. (Milwaukee time) on the date of prepayment. Such prepayment
of Domestic Rate or Eurocurrency Loans, as the case may be, shall be made by the
payment of the principal amount to be prepaid and accrued interest thereon to
the date fixed for prepayment plus, in the case of a prepayment of Eurocurrency
Loans on a date prior to the last day of the applicable Interest Period, any
amount payable under Section 3.6. The Agent will promptly advise each Bank of
any such prepayment notice with respect to Committed Revolving Loans it receives
from the Borrower. Any amount paid or prepaid on the Committed Revolving Loans
before the Revolving Credit Termination Date may, subject to the terms and
conditions of this Agreement, be borrowed, repaid and borrowed again.

                  (b) Swing Loans. The Borrower may prepay any Swing Loans in
whole or in part upon notice delivered to Firstar no later than 11 a.m.
(Milwaukee time) on the date of prepayment specifying the principal amount to be
prepaid. Any amount paid or prepaid on Swing Loans before the Revolving Credit
Termination Date may, subject to the terms and conditions of this Agreement, be
borrowed, repaid and borrowed again.

                  (c) Mandatory Prepayments. If, within thirty (30) days after
receiving notice under Section 9.6(c) of a Change of Control Event, the Required
Banks notify the Borrower that they require prepayment of the Notes, on the date
set forth in such notice (which date shall be no earlier than (x) five (5) days
after such notice is given or (y) the day on which the Borrower repays any other
Debt before its original scheduled due date, whichever day is earlier) the
Borrower shall pay in full all Obligations then outstanding, including the

established pursuant to Sections 1.5(c) hereof,

                (c) any failure by the Borrower to make any payment of principal
on any Eurocurrency Loan when due (whether by acceleration or otherwise), or

                (d) any acceleration of the maturity of a Eurocurrency Loan as a
result of the occurrence of any Event of Default hereunder,

then, upon the demand of such Bank, the Borrower shall pay to such Bank such

makes such a claim for compensation, it shall provide to the Borrower, with a

forth the amount of such loss, cost or expense in reasonable detail (including
an explanation of the basis for and the computation of such loss, cost or

organized and existing in good standing under the laws of the State of Delaware;
has all necessary corporate power to carry on its present business; and is duly
licensed or qualified and in good standing in each jurisdiction in which the
nature of the business transacted by it or the nature of the Property owned or
leased by it makes such licensing, qualification or good standing necessary and
in which the failure to be so licensed, qualified or in good standing would
materially and adversely affect its business, operations, Property or financial
or other condition.

                7.2. Subsidiaries. Schedule 7.2 (as updated from time to time
pursuant to Section 9.1) hereto identifies each Subsidiary (and whether such
Subsidiary is a Significant Subsidiary), the jurisdiction of its incorporation,

stock owned by the Borrower and its Subsidiaries and, if such percentage is not
100% (excluding directors' qualifying shares as required by law), a description
of each class of its authorized capital stock and the number of shares of each
class issued and outstanding. Each Subsidiary is duly incorporated and existing
in good standing as a corporation under the laws of the jurisdiction of its
incorporation, has all necessary corporate power to carry on its present
business, and is duly licensed




                                       37
<PAGE>   45


or qualified and in good standing in each jurisdiction in which the nature of
the business transacted by it or the nature of the Property owned or leased by
it makes such licensing or qualification necessary and in which the failure to
be so licensed or qualified would have a material adverse effect on the
business, operations, Property or financial or other condition of such
Subsidiary. All of the issued and outstanding shares of capital stock of each
Subsidiary are validly issued and outstanding and fully paid and nonassessable.
All such shares owned by the Borrower are owned beneficially, and of record,
free of any Lien. Each Significant Subsidiary is a Guarantor.

                7.3. Corporate Authority and Validity of Obligations. The
Borrower has full right and authority to enter into this Agreement and the other
Credit Documents to which it is a party, to make the borrowings herein provided
for, to issue its Notes in evidence thereof, to apply for the issuance of the
Letters of Credit, and to perform all of its obligations under the Credit
Documents to which it is a party. Each Guarantor has full right and authority to
enter into this Agreement as a signatory hereto or pursuant to a Subsidiary
Guarantee Agreement and to perform all of its obligations hereunder. Each Credit
Document to which it is a party has been duly authorized, executed and delivered
by the Borrower and each Guarantor and constitutes valid and binding obligations
of the Borrower and each Guarantor enforceable in accordance with its terms. No
Credit Document, nor the performance or observance by the Borrower or any
Guarantor of any of the matters or things therein provided for, contravenes any
provision of law or any charter or by-law provision of the Borrower or any
Guarantor or (individually or in the aggregate) any material Contractual
Obligation of or affecting the Borrower or any Guarantor or any of their
respective Properties or results in or requires the creation or imposition of
any Lien on any of the Properties or revenues of the Borrower or any Guarantor.

                7.4. Financial Statements.

Subsidiaries as at November 28, 1998 and the related consolidated statements of

operations and cash flows for the periods then ended in conformity with
generally accepted accounting principles applied on a consistent basis. Neither
the Borrower nor any Subsidiary has contingent liabilities which are material to
it other than as indicated on such financial statements or, with respect to
future periods, on the financial statements furnished pursuant to Section 9.6
hereof. Since May 29, 1999, there has been no material adverse change in the
business, operations, Property or financial or other condition, or business
prospects, of the Borrower and its Subsidiaries taken as a whole.

                     (b) The Borrower has furnished to the Banks a pro forma
balance sheet of the Borrower and its Subsidiaries, reflecting the Mark IV
Acquisition, dated August 31, 1999 (the "Pro Forma Balance Sheet") and projected
sales and operating profit of the Borrower and its Subsidiaries, reflecting the
Mark IV Acquisition, for the periods ending on November 30 of the next five
years (the "Projections"). To the knowledge of the Borrower (a) the Pro Forma
Balance Sheet fairly presents the financial condition of the Borrower and its
Subsidiaries after giving effect to the Mark IV Acquisition and there are no
omissions from the Pro Forma Balance Sheet, or other facts and circumstances not
reflected in the Pro Forma Balance Sheet, which would be material under GAAP and
(b) the assumptions used in the preparation of the Projections are reasonable
and there are no presently existing facts or circumstances not reflected in the
Projections which are reasonably expected to cause a material adverse change in
the information set forth in the Projections.

                7.5. No Litigation; No Labor Controversies.

                     (a) There is no litigation or governmental proceeding
pending, or to the knowledge of the Borrower or any Guarantor threatened,
against the Borrower or any Subsidiary which is reasonably expected to be
adversely determined and if adversely determined, would (individually or in the
aggregate, insofar as the Borrower may reasonably foresee) reasonably be
expected to materially adversely affect the business, operations, Property or
financial or other condition of the Borrower and its Subsidiaries taken as a
whole.

                     (b) There are no labor controversies pending or, to the
knowledge of the Borrower or any Guarantor, threatened against the Borrower or
any Subsidiary which would (individually or in the aggregate, insofar as the
Borrower may reasonably foresee) reasonably be expected to, or which actually
do, materially adversely affect the business, operations, Property or financial
or other condition of the Borrower and its Subsidiaries taken as a whole.

                7.6. Taxes. The Borrower and its Subsidiaries have filed all
United States federal tax returns, and all other tax returns, required to be
filed and have paid all taxes due pursuant to such returns or pursuant to any
assessment received by the Borrower or any Subsidiary, except such taxes, if
any, as are being contested in good faith and for which adequate reserves have
been provided. No notices of tax liens have been filed and no claims are being
asserted concerning any such taxes, which liens or claims are material to the
financial condition of the Borrower and its Subsidiaries on a consolidated basis
taken as a whole. The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries for any taxes or other governmental charges are
adequate.

                7.7. Approvals. No authorization, consent, license, exemption,
filing or registration with any court or governmental department, agency or
instrumentality, nor any approval or consent of the stockholders of the Borrower
or any Subsidiary or from any other Person, is necessary for the valid
execution, delivery or performance by the Borrower or any Subsidiary of any
Credit Document to which it is a party, except for such thereof as have been
obtained and are in full force and effect.

                7.8. ERISA. With respect to each Plan, the Borrower and each
other member of the Controlled Group have fulfilled their obligations under the
minimum funding standards of and are in compliance in all material respects with
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and
with the Code to the extent applicable to each of them and have not incurred any
liability to the Pension Benefit Guaranty Corporation ("PBGC") or a Plan under
Title IV of ERISA other than a liability to the PBGC for premiums under Section
4007 of ERISA. Neither the Borrower nor any Subsidiary has any contingent
liabilities for any post-retirement benefits under a Welfare Plan, other than
liability for continuation coverage described in Part 6 of Title I of ERISA.

                7.9. Government Regulation. Neither the Borrower nor any
Subsidiary is an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended, or a "holding company", or a "Subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "Subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

                7.10. Margin Stock. Neither the Borrower nor any Subsidiary is
engaged principally, or as one of its primary activities, in the business of
extending credit for the purpose of purchasing or carrying margin stock ("margin
stock" to have the same meaning herein as in Regulation U of the Board of
Governors of the



                                       40

Federal Reserve System). The Borrower will not use the proceeds of any Loan or
Letter of Credit in a manner that violates any provision of Regulation U or X of
the Board of Governors of the Federal Reserve System.

                7.11. Licenses and Authorizations: Compliance with Environmental
and Health Laws. The Borrower and each of its Subsidiaries has all necessary
licenses, permits and governmental authorizations to own and operate its
Properties and to carry on its business as currently conducted and contemplated,
except where the failure to maintain such licenses, permits and authorizations
would (individually or in the aggregate, insofar as the Borrower may reasonably
foresee) not reasonably be expected to have, and does not actually have, a
material adverse effect on the business, operations, Property or financial or
other condition of the Borrower and its Subsidiaries taken as a whole. The
Borrower and its Subsidiaries are in compliance with all Environmental and
Health Laws, except where the failure to comply would not be reasonably expected
to have, and actually does not have, a material adverse effect on the business,
operations, Property or financial or other condition of the Borrower and its
Subsidiaries taken as a whole. Neither the Borrower nor any Subsidiary has
given, nor is it required to give, nor has the Borrower or any Subsidiary
received, any notice, letter, citation, order, warning, complaint, inquiry,
claim or demand to or from any governmental entity or in connection with any
court proceeding which would reasonably be expected to have a material adverse
effect on the Property, business or operations of the Borrower and its
Subsidiaries taken as a whole claiming that: (i) the Borrower or any Subsidiary
has violated, or is about to violate, any Environmental and Health Law; (ii)
there has been a release, or there is a threat of release, of Hazardous
Materials from the Borrower's or any Subsidiary's Property, facilities,
equipment or vehicles; (iii) the Borrower or any Subsidiary may be or is liable,
in whole or in part, for the costs of cleaning up, remediating or responding to
a release of Hazardous Materials; or (iv) any of the Borrower's or any
Subsidiary's property or assets are subject to a Lien in favor of any
governmental entity for any liability, costs or damages, under any Environmental
and Health Law arising from, or costs incurred by such governmental entity in
response to, a release of a Hazardous Materials.

                7.12. Ownership of Property; Liens. The Borrower and its
Subsidiaries each have good and defensible title to their assets as reflected on
the most recent consolidated balance sheet of the Borrower and its Subsidiaries
furnished to the Banks (except for sales of assets by the Borrower and its
Subsidiaries in the ordinary course of business), subject to no Liens other than
such thereof as are permitted by Section 9.9 hereof.

<PAGE>   49


                7.13. No Burdensome Restrictions: Compliance with Agreements.
Neither the Borrower nor any Subsidiary is (a) party or subject to any law,
regulation, rule or order, or any Contractual Obligation that (individually or
in the aggregate) materially adversely affects the business, operations,
Property or financial or other condition of the Borrower and its Subsidiaries
taken as a whole or (b) in default in the performance, observance or fulfillment
of any of the obligations, covenants or conditions contained in any agreement to
which it is a party, which default materially adversely affects the business,
operations, Property or financial or other condition of the Borrower and its
Subsidiaries taken as a whole.

                7.14. Full Disclosure. All information heretofore furnished by
the Borrower or any Guarantor to the Agent or any Bank for purposes of or in
connection with the Credit Documents or any transaction contemplated thereby is,
and all such information hereafter furnished by the Borrower or any Guarantor to
the Agent or any Bank will be, true and accurate in all material respects and
not misleading on the date as of which such information is stated or certified
(it being understood that with respect to projections, such projections are good
faith estimates based on assumptions believed to be reasonable by the Borrower
at the time of delivery of such projections to the Agent and the Banks and that
no assurances can be given that the results set forth in the projections will
actually be obtained).

                7.15. Year 2000. The Borrower has made a full and complete
assessment of the Year 2000 Issues and has a realistic and achievable program
for remediating the Year 2000 Issues on a timely basis (the "Year 2000
Program"). Based on such assessment and the Year 2000 Program, the Borrower does
not reasonably anticipate that Year 2000 Issues will have a material adverse
effect on the business operations, Property or financial or other condition of
the Borrower and its Subsidiaries taken as a whole.

         8.     Conditions Precedent. The obligation of each Bank to advance
any Loan or of the Issuing Bank to issue, extend the expiration date (including
by not giving notice of non-renewal) of or increase the amount of any Letter of
Credit, shall be subject to the following conditions precedent:

<PAGE>   52


receives Loans to pay the purchase price for the Mark IV Acquisition, the

         9.     Covenants. The Borrower covenants and agrees that, so long as
any Note or any L/C Obligation is outstanding hereunder, or any Commitment is
available to or in use by the Borrower hereunder, except to the extent
compliance in any case is waived in writing by the Required Banks:

                9.1. Corporate Existence; Subsidiaries. The Borrower shall, and
shall cause each of its Subsidiaries to, preserve and maintain its corporate
existence; provided, however, that nothing in this Section shall prevent mergers
and consolidations permitted by Section 9.12 hereof or the discontinuation of
the corporate existence of any Non-Material Subsidiary if discontinuance of such
Non-Material Subsidiary is desirable in the conduct of the Borrower's business;
provided the aggregate total revenues of all Non-Material Subsidiaries whose
corporate existence is discontinued during any fiscal year may not exceed
$25,000,000. As a condition to establishing or acquiring any Significant
Subsidiary and within 15 days after a Subsidiary otherwise becomes a Significant
Subsidiary, unless the Required Banks otherwise agree, the Borrower shall (i)
cause such Significant Subsidiary to execute a Subsidiary Guarantee




                                       45

Agreement, (ii) cause such Subsidiary to deliver documentation similar to that

Guarantor hereunder and under the Subsidiary Guarantee Agreement in form and
substance satisfactory to the Required Banks and (iii) if necessary, deliver an
updated Schedule 7.2 to reflect the new Subsidiary.

conduct of its business in good repair, working order and condition and will
from time to time make all necessary repairs, renewals, replacements, additions
and betterments thereto so that at all times such plants, Properties and
equipment shall be preserved and maintained, and the Borrower will cause each of
its Subsidiaries to do so in respect of Property owned or used by it; provided,
however, that nothing in this Section 9.2 shall prevent the Borrower or a
Subsidiary from discontinuing the operation or maintenance of any such
Properties if such discontinuance is, in the judgment of the Borrower, desirable
in the conduct of its business or the business of its Subsidiary.

                9.3. Taxes. The Borrower will duly pay and discharge, and will
cause each of its Subsidiaries duly to pay and discharge, all taxes, rates,
assessments, fees and governmental charges upon or against it or against its
Properties, in each case before the same become delinquent and before penalties
accrue thereon, unless and to the extent that the same are being contested in
good faith by appropriate proceedings and reserves in conformity with GAAP have
been provided therefor on the books of the Borrower.

                9.4. ERISA. The Borrower will, and will cause each of its
Subsidiaries to, promptly pay and discharge all obligations and liabilities
arising under ERISA of a character which if unpaid or unperformed could
reasonably be expected to result in the imposition of a Lien against any of its

any reportable event (as defined in ERISA) affecting a Plan, other than any such
event of which the PBGC has waived notice by regulation, (ii) receipt of any
notice from the PBGC of its intention to seek termination of any Plan or
appointment of a trustee therefor, (iii) its or any of its Subsidiaries'
intention to terminate or withdraw from any Plan, and (iv) the occurrence of any

material increase in the contingent liability of the Borrower or any of its
Subsidiaries under any post-retirement Welfare Plan benefit. The Agent will
promptly distribute to each Bank any notice it receives from the Borrower
pursuant to this Section 9.4.

character and to the extent usually insured (subject to self-insured retentions

in good faith by management of the Borrower. To the extent usually insured
(subject to self-insured retentions and deductibles) in accordance with
reasonable business practices as determined in good faith by management of the
Borrower, the Borrower will also insure, and cause each of its Subsidiaries to
insure such other hazards and risks (including employers' and public and product
liability risks) with good and responsible insurance companies. The Borrower
will upon request of the Agent furnish to the Agent (which shall promptly
furnish the same to each Bank) a summary setting forth the nature and extent of
the insurance maintained pursuant to this Section 9.5.

                     (ii)  of any default or event of default under any
Contractual Obligation of the Borrower or any of its Subsidiaries, except for a

adverse effect on the business, operations, Property or financial or other
condition of the Borrower and its Subsidiaries taken as a whole;

                     (iii) of a material adverse change in the business,

properties of the Borrower or any of its Subsidiaries, to examine all of their
books of account, records, reports and other papers, to make copies and extracts

Banks (and such officers, agents, accountants or other representatives of such
Bank as any Bank may designate) the finances and affairs of the Borrower and its
Subsidiaries) all at such reasonable times and as often as may be reasonably
requested. The Borrower shall not be liable under Section 14.15 hereof for the
cost of any action taken solely under the authority of this Section unless such
action has been taken upon the occurrence and during the continuation of any
Default or Event of Default.

                9.8. Conduct of Business. Neither the Borrower nor any
Subsidiary will engage in any line of business if, as a result, the general

without limitation stock in Subsidiaries) sold, leased, transferred or disposed
of by the Borrower and its Subsidiaries during such fiscal year (other than
inventory in the ordinary course of business) and the aggregate consideration
received by Subsidiaries from their issuance or sale of their stock during such

appointment continues undischarged or such proceeding continues undismissed or
unstayed for a period of sixty (60) days;

                      (h) the Borrower or any Subsidiary shall fail within
thirty (30) days to pay, bond or otherwise discharge any judgment or order for
the payment of money in excess of $2,000,000, which is not stayed on appeal or
otherwise being appropriately contested in good faith in a manner that stays
execution thereon; or

                      (i) The Borrower or any other member of the Controlled
Group shall fail to pay when due an amount or amounts aggregating in excess of
$500,000 which it shall have become liable to pay to the PBGC or to a Plan under
Title IV of ERISA; or notice of intent to terminate a Plan or Plans having
aggregate Unfunded Vested Liabilities in excess of $500,000 (collectively, a
"Material Plan") shall be filed under Title IV of ERISA by the Borrower or any
Subsidiary or any other member of the Controlled Group, any plan administrator
or any combination of the foregoing; or the PBGC shall institute proceedings
under Title IV of ERISA to terminate or to cause a trustee to be appointed to
administer any Material Plan or a proceeding shall be instituted by a fiduciary
of any Material Plan against the Borrower or any other member of the Controlled
Group to enforce Section 515 or 4219(c)(5) of ERISA and such proceeding shall
not have been dismissed within thirty (30) days thereafter; or a condition shall
exist by reason of which the PBGC would be entitled to obtain a decree
adjudicating that any Material Plan must be terminated.

                10.2. Non-Bankruptcy Defaults. When any Event of Default other
than those described in subsections (f) or (g) of Section 10.1 hereof has
occurred and is continuing, the Agent shall, by written notice to the Borrower:
(a) if so directed by the Required Banks, terminate the remaining Commitments
and Swing Line Commitment and all other obligations of the Banks hereunder on
the date




                                       60
<PAGE>   68


stated in such notice (which may be the date thereof); (b) if so directed by the
Required Banks, declare the principal of and the accrued interest on all
outstanding Notes to be forthwith due and payable and thereupon all outstanding
Notes, including both principal and interest thereon, shall be and become
immediately due and payable together with all other amounts payable under the
Credit Documents without further demand, presentment, protest or notice of any
kind; and (c) if so directed by the Required Banks, demand that the Borrower
immediately pay to the Agent subject to Section 10.4, the full amount then
available for drawing under each or any Letter of Credit, and the Borrower
agrees to immediately make such payment and acknowledges and agrees that the
Banks shall have the right to require the Borrower to specifically perform such
undertaking whether or not any drawings or other demands for payment have been
made under any Letter of Credit. The Agent, after giving notice to the Borrower
pursuant to Section 10.1(c) or this Section 10.2, shall also promptly send a
copy of such notice to the other Banks, but the failure to do so shall not
impair or annul the effect of such notice.

                10.3. Bankruptcy Defaults. When any Event of Default described
in subsections (f) or (g) of Section 10.1 hereof has occurred and is continuing,
then all outstanding Notes shall immediately become due and payable together
with all other amounts payable under the Credit Documents without presentment,
demand, protest or notice of any kind, the obligation of the Banks to extend
further credit pursuant to any of the terms hereof shall immediately terminate
and the Borrower shall immediately pay to the Agent, subject to Section 10.4,
the full amount then available for drawing under all outstanding Letters of
Credit, the Borrower acknowledging that the Banks, and the Agent on their
behalf, shall have the right to require the Borrower to specifically perform
such under-taking whether or not any draws or other demands for payment have
been made under any of the Letters of Credit.

                10.4. Collateral for Undrawn Letters of Credit.

                      (a) If the payment or prepayment of the amount available
for drawing under any or all outstanding Letters of Credit is required under
Section 10.2 or 10.3 above, the Borrower shall forthwith pay the amount required
to be so paid or prepaid, to be held by the Agent as provided in subsection (b)
below.

                      (b) All amounts prepaid pursuant to subsection (a) above
shall be held by the Agent in a separate collateral account (such account, and
the credit balances, properties and any investments from time to time held
therein, and any substitutions for such account, any certificate of deposit or
other instrument




                                       61
<PAGE>   69


evidencing any of the foregoing and all proceeds of and earnings on any of the
foregoing being collectively called the "Account") as security for, and for
application by the Agent (to the extent available) to, the reimbursement of any
payment under any Letter of Credit then or thereafter made by the Issuing Bank,
and to the payment of the unpaid balance of any Loans and all other Obligations,
any such applications to be made in such order. The Account shall be held in the
name of and subject to the exclusive dominion and control of the Agent for the
benefit of the Agent, the Issuing Bank and the Banks. If and when requested by
the Borrower, the Agent shall invest funds held in the Account from time to time
in direct obligations of, or obligations the principal of and interest on which
are unconditionally guaranteed by, the United States of America with a remaining
maturity of one year or less, provided that the Agent is irrevocably authorized
to sell investments held in the Account when and as required to make payments
out of the Account for application to amounts due and owing from the Borrower to
the Agent, the Issuing Bank or Banks; provided, however, that if (i) the
Borrower shall have made payment of all such obligations referred to in
subsection (a) above and (ii) no Letters of Credit, Commitments, Loans or other
Obligations remain outstanding hereunder, then the Agent shall repay to the
Borrower any remaining amounts held in the Account.

                10.5. Notice of Default. The Agent shall give notice to the
Borrower under Section 10.1(c) hereof promptly upon being requested to do so by
any Bank and shall thereupon notify all the Banks thereof.

                10.6. Expenses. The Borrower agrees to pay to the Agent and each
Bank, and any other holder of any Note outstanding hereunder, all reasonable
expenses incurred or paid by the Agent and such Bank or any such holder,
including reasonable attorneys' fees and court costs, in connection with any
Default or Event of Default by the Borrower hereunder or in connection with the
enforcement of any of the Credit Documents.

         11.    Change in Circumstances.

                11.1. Change of Law. Notwithstanding any other provisions of
this Agreement or any Note, if at any time after the date hereof any change in
applicable law or regulation or in the interpretation thereof makes it unlawful
for any Bank to make or continue to maintain Eurocurrency Loans or to perform
its obligations as contemplated hereby, such Bank shall promptly give notice
thereof to the Borrower and such Bank's obligations to make or maintain
Eurocurrency Loans under this Agreement shall terminate until it is no longer
unlawful for such Bank to make or maintain Eurocurrency Loans. The Borrower
shall prepay on demand the outstanding principal amount of any such affected
Eurocurrency




                                       62
<PAGE>   70


Loans, together with all interest accrued thereon at a rate per annum equal to
the interest rate applicable to such Loan; provided, however, that (i) the
Borrower may delay such prepayment until the last day of the then-current
Interest Period for such affected Eurodollar Loans if permitted by law and (ii)
subject to all of the terms and conditions of this Agreement, the Borrower may
then elect to borrow the principal amount of the affected Eurocurrency Loans
from such Bank, by means of Domestic Rate Loans from such Bank, which Domestic
Rate Loans shall not be made ratably by the Banks but only from such affected
Bank. The Borrower shall not be required to pay any amount under Section 3.6 in
connection with any prepayment required by this Section 11.1.

                11.2. Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any Borrowing of Eurocurrency Loans:

                      (a) the Agent determines that deposits in U.S. Dollars or
the applicable Alternative Currency (in the applicable amounts) are not being
offered to it in the eurocurrency interbank market for such Interest Period, or
that by reason of circumstances affecting the interbank eurocurrency market
adequate and reasonable means do not exist for ascertaining the applicable
LIBOR, or

                      (b) any Bank shall advise the Agent that LIBOR as
determined by the Agent will not adequately and fairly reflect the cost to such
Bank of funding its Eurocurrency Loan for such Interest Period for a reason
other than an increase in funding costs resulting from a decrease in the
creditworthiness of such Bank,

then the Agent shall forthwith give notice thereof to the Borrower and the
Banks, whereupon until the Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks to
make Eurocurrency Loans in the currency so affected shall be suspended.

                11.3. Increased Cost and Reduced Return.

                      (a) If, on or after the date hereof, the adoption of any
applicable law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Lending Office) with any request or
directive (whether or not having the force of law but, if not having the force
of law, compliance with which is customary in the relevant jurisdiction) of any
such authority, central bank or comparable agency:



                                       63
<PAGE>   71


                          (i) shall subject any Bank (or its Lending Office) to
any tax, duty or other charge with respect to its Eurocurrency Loans, its Notes,
its Letter(s) of Credit, or its participation in any thereof, any Reimbursement
Obligations owed to it or its obligation to make Eurocurrency Loans, issue a
Letter of Credit, or to participate therein, or shall change the basis of
taxation of payments to any Bank (or its Lending Office) of the principal of or
interest on its Eurocurrency Loans, Letter(s) of Credit, or participations
therein or any other amounts due under this Agreement in respect of its
Eurocurrency Loans, Letter(s) of Credit, or participations therein, any
Reimbursement Obligations owed to it, or its obligation to make Eurocurrency
Loans, issue a Letter of Credit, or acquire participations therein (except for
changes in any tax on the overall net income or profits of such Bank or its
Lending Office imposed by the jurisdiction in which such Bank or its lending
office is incorporated in which such Bank's principal executive office or
Lending Office is located); or

                          (ii) shall impose, modify or deem applicable any
reserve, special deposit or similar requirement (including, without limitation,
any such requirement imposed by the Board of Governors of the Federal Reserve
System, but excluding with respect to any Eurocurrency Loans any such
requirement included in an applicable Eurocurrency Reserve Percentage) against
assets of, deposits with or for the account of, or credit extended by, any Bank
(or its Lending Office) or shall impose on any Bank (or its Lending Office) or
on the interbank market any other condition affecting its Eurocurrency Loans,
its Notes, its Letter(s) of Credit, or its participation in any thereof, any
Reimbursement Obligation owed to it, or its obligation to make Eurocurrency
Loans, to issue a Letter of Credit, or to participate therein;

and the result of any of the foregoing is to increase the cost to such Bank (or
its Lending Office) of making or maintaining any Eurocurrency Loan, issuing or
maintaining a Letter of Credit, or participating therein, or to reduce the
amount of any sum received or receivable by such Bank (or its Lending Office)
under this Agreement or under its Notes with respect thereto, by an amount
deemed by such Bank to be material, then, within ten (10) days after demand by
such Bank (with a copy to the Agent) at any time within 120 days after the date
on which such Bank knows or has reason to know of its right to additional
compensation under this Section 11.3(a), the Borrower shall promptly pay to such
Bank such additional amount or amounts as will compensate such Bank for such
increased cost or reduction; provided, however, that if any such Bank fails to
make demand within such 120-day period, such Bank shall only be entitled to
additional compensation for any such costs incurred from and after the date that
is 120 days prior to the date such Bank makes such demand; and provided further
that before making any




                                       64
<PAGE>   72


such demand, each Bank agrees to use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to designate a different
Lending Office if the making of such a designation would avoid the need for, or
reduce the amount of, such increased cost and would not, in the reasonable
judgment of such Bank, be otherwise disadvantageous to such Bank.

                (b) If, after the date hereof, any Bank or the Agent shall have
determined that the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change therein (including, without limitation, any
revision in the Final Risk-Based Capital Guidelines of the Board of Governors of
the Federal Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225,
Appendix A) or of the Office of the Comptroller of the Currency (12 CFR Part 3,
Appendix A), or in any other applicable capital rules heretofore adopted and
issued by any governmental authority), or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Lending Office) with any request or directive regarding
capital adequacy (whether or not having the force of law but, if not having the
force of law, compliance with which is customary in the applicable jurisdiction)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Bank's capital, or on the capital
of any corporation controlling such Bank, as a consequence of its obligations
hereunder to a level below that which such Bank could have achieved but for such
adoption, change or compliance (taking into consideration such Bank's policies
with respect to capital adequacy) by an amount deemed by such Bank to be
material, then from time to time, within ten (10) days after demand by such Bank
(with a copy to the Agent) at any time within 120 days after the date on which
such Bank knows or has reason to know of its right to additional compensation
under this Section 11.3(b), the Borrower shall pay to such Bank such additional
amount or amounts as will compensate such Bank for such reduction; provided,
however, that if any such Bank fails to make demand within such 120-day period,
such Bank shall only be entitled to additional compensation for any such costs
incurred from and after the date that is 120 days prior to the date such Bank
makes such demand.

                (c) No Bank may request additional amounts under this Section
11.3 unless it is generally making similar requests of other borrowers similarly
situated. A certificate of any Bank claiming compensation under this Section
11.3 and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of demonstrable error. In
determining such amount, such Bank may use any reasonable averaging and
attribution methods.




                                       65

                11.4. Lending Offices. Each Bank may, at its option, elect to
make its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof (each a "Lending Office") for each type of
Loan available hereunder or at such other of its branches, offices or affiliates
as it may from time to time elect and designate in a written notice to the
Borrower and the Agent.

                11.5. Discretion of Bank as to Manner of Funding.
Notwithstanding any other provision of this Agreement, each Bank shall be
entitled to fund and maintain its funding of all or any part of its Loans in any
manner it sees fit, it being understood, however, that for the purposes of this
Agreement all determinations hereunder shall be made as if each Bank had
actually funded and maintained each Eurocurrency Loan that is a Committed
Revolving Loan through the purchase of deposits of U.S. Dollars or the
applicable Alternative Currency in the Eurocurrency interbank market having a
maturity corresponding to such Loan's Interest Period and bearing an interest
rate equal to LIBOR for such Interest Period.

         12.    The Agent and the Co-Agents.

                12.1. Appointment and Authorization of Agent. Each Bank hereby
appoints Firstar Bank Milwaukee, National Association as the Agent under the
Credit Documents and hereby authorizes the Agent to take such action as Agent on
its behalf and to exercise such powers under the Credit Documents as are
delegated to the Agent by the terms thereof, together with such powers as are
reasonably incidental thereto. The Banks expressly agree that the Agent is not
acting as a fiduciary of the Banks in respect to the Credit Documents, the
Borrowers or otherwise, and nothing herein or in any of the other Credit
Documents shall result in any duties or obligations on the Agent or any of the
Banks except as expressly set forth herein.

                  12.2. Agent and its Affiliates. The Agent shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Bank and may exercise or refrain from exercising the same as though it
were not the Agent, and the Agent and its affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with the Borrower or
any Affiliate of the Borrower as if it were not the Agent under the Credit
Documents. The term "Bank" as used herein and in all other Credit Documents,
unless the context otherwise clearly requires, includes the Agent in its
individual capacity as a Bank.

                  12.3. Action by Agent. If the Agent receives from the Borrower
a written notice of an Event of Default pursuant to Section 9.6(c)(i) hereof,
the Agent shall promptly give each of the Banks written notice thereof. The




                                       66
<PAGE>   74


obligations of the Agent under the Credit Documents are only those expressly set
forth therein. Without limiting the generality of the foregoing, the Agent shall
not be required to take any action hereunder with respect to any Default or
Event of Default, except as expressly provided in Sections 10.2 and 10.5. In no
event, however, shall the Agent be required to take any action in violation of
applicable law or of any provision of any Credit Document, and the Agent shall
in all cases be fully justified in failing or refusing to act hereunder or under
any other Credit Document unless it shall be first indemnified to its reasonable
satisfaction by the Banks against any and all costs, expense, and liability
which may be incurred by it by reason of taking or continuing to take any such
action. The Agent shall be entitled to assume that no Default or Event of
Default exists unless notified to the contrary by a Bank or the Borrower. In all
cases in which this Agreement and the other Credit Documents do not require the
Agent to take certain actions, the Agent shall be fully justified in using its
discretion in failing to take or in taking any action hereunder and thereunder.

                12.4. Consultation with Experts. The Agent may consult with
legal counsel, independent public accountants and other experts selected by it
and shall not be liable for any action taken or omitted to be taken by it in
good faith in accordance with the advice of such counsel, accountants or
experts.

                12.5. Liability of Agent; Credit Decision. Neither the Agent nor
any of its directors, officers, agents, or employees shall be liable for any
action taken or not taken by it in connection with the Credit Documents (i) with
the consent or at the request of the Required Banks or (ii) in the absence of
its own gross negligence or willful misconduct. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made in connection with this Agreement, any other Credit Document
or any Credit Event, (ii) the performance or observance of any of the covenants
or agreements of the Borrower or any Guarantor contained herein or in any other
Credit Document; (iii) the satisfaction of any condition specified in Section 8
hereof, except receipt of items required to be delivered to the Agent; or (iv)
the validity, effectiveness, genuineness, enforceability, perfection, value,
worth or collectibility hereof or of any other Credit Document or of any other
documents or writing furnished in connection with any Credit Document; and, the
Agent makes no representation of any kind or character with respect to any such
matter mentioned in this sentence. The Agent may execute any of its duties under
any of the Credit Documents by or through employees, agents, and
attorneys-in-fact and shall not be answerable to the Banks, the Borrower, or any
Guarantor or any other Person for the default or misconduct of any such agents
or attorneys-in-fact selected with reasonable care. The Agent shall not incur
any liability by acting in reliance upon any notice,




                                       67
<PAGE>   75


consent, certificate, other document or statement (whether written or oral)
believed by it to be genuine or to be sent by the proper party or parties. In
particular and without limiting any of the foregoing, the Agent shall have no
responsibility for confirming the accuracy of any Compliance Certificate or
other document or instrument received by it under the Credit Documents. The
Agent may treat the payee of any Note as the holder thereof until written notice
of transfer shall have been filed with the Agent signed by such payee in form
satisfactory to the Agent. Each Bank acknowledges that it has independently and
without reliance on the Agent or any other Bank, and based upon such
information, investigations and inquiries as it deems appropriate, made its own
credit analysis and decision to extend credit to the Borrower in the manner set
forth in the Credit Documents. It shall be the responsibility of each Bank to
keep itself informed as to the creditworthiness of the Borrower and the
Guarantors, and the Agent shall have no liability to any Bank with respect
thereto.

                12.6. Indemnity. The Banks shall ratably, in accordance with
their respective Percentages, indemnify and hold the Agent, and its directors,
officers, employees, agents and representatives harmless from and against any
liabilities, losses, costs or expenses suffered or incurred by it under any
Credit Document or in connection with the transactions contemplated thereby,
regardless of when asserted or arising, except to the extent they are promptly
reimbursed for the same by the Borrower and except to the extent that any event
giving rise to a claim was caused by the gross negligence or willful misconduct
of the party seeking to be indemnified. The obligations of the Banks under this
Section 12.6 shall survive termination of this Agreement.

                12.7. Resignation of Agent and Successor Agent. The Agent may,
and shall at the request of the Required Banks, resign at any time by giving
written notice thereof to the Banks and the Borrower. Upon any such resignation
of the Agent, the Required Banks shall have the right to appoint a successor
Agent with the consent of the Borrower. If no successor Agent shall have been so
appointed by the Required Banks, and shall have accepted such appointment,
within thirty (30) days after the retiring Agent's giving of notice of
resignation, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be any Bank hereunder or any commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $200,000,000. Upon the
acceptance of its appointment as the Agent hereunder, such successor Agent shall
thereupon succeed to and become vested with all the rights and duties of the
retiring or removed Agent under the Credit Documents, and the retiring Agent
shall be discharged from its duties and obligations thereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Section
13 and all protective provisions of the other Credit




                                       68
<PAGE>   76


Documents shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent.

                12.8. Co-Agents. Neither of the Persons identified on the facing
page or signature pages of this Agreement as a co-agent shall have any right,
power, obligation, liability, responsibility or duty under this Agreement other
than those applicable to all Banks as such. Without limiting the foregoing, none
of the Banks so identified shall have or be deemed to have any fiduciary
relationship with any Bank. Each Bank acknowledges that it has not relied, and
will not rely, on any of the Banks so identified in deciding to enter into this
Agreement or in taking or not taking action hereunder.

         13.    The Guarantees.

                13.1. The Guarantees. To induce the Banks to provide the credits
described herein and in consideration of benefits expected to accrue to each
Guarantor by reason of the Commitments and for other good and valuable
consideration, receipt of which is hereby acknowledged, each Guarantor hereby
unconditionally and irrevocably guarantees jointly and severally to the Agent,
the Banks, and each other holder of an Obligation, the due and punctual payment
of all present and future indebtedness of the Borrower evidenced by or arising
out of the Credit Documents, including, but not limited to, the due and punctual
payment of principal of and interest on the Notes and the due and punctual
payment of all other Obligations now or hereafter owed by the Borrower under the
Credit Documents as and when the same shall become due and payable, whether at
stated maturity, by acceleration or otherwise, according to the terms hereof and
thereof. In case of failure by the Borrower punctually to pay any indebtedness
or other Obligations guaranteed hereby, each Guarantor hereby unconditionally
agrees jointly and severally to make such payment or to cause such payment to be
made punctually as and when the same shall become due and payable, whether at
stated maturity, by acceleration or otherwise, and as if such payment were made
by the Borrower.

                13.2. Guarantee Unconditional. The obligations of each Guarantor
as a guarantor under this Section 13 shall be unconditional and absolute and,
without limiting the generality of the foregoing, shall not be released,
discharged or otherwise affected by:

                      (a) any extension, renewal, settlement, compromise, waiver
or release in respect of any obligation of the Borrower or of any other
Guarantor under this Agreement or any other Credit Document or by operation of
law or otherwise;



                                       69
<PAGE>   77


                      (b) any modification or amendment of or supplement to this
Agreement or any other Credit Document;

                      (c) any change in the corporate existence, structure or
ownership of, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting, the Borrower, any other Guarantor, or any of their
respective assets, or any resulting release or discharge of any obligation of
the Borrower or of any other Guarantor contained in any Credit Document;

                      (d) the existence of any claim, set-off or other rights
which the Guarantor may have at any time against the Agent, any Bank or any
other Person, whether or not arising in connection herewith;

                      (e) any failure to assert, or any assertion of, any claim
or demand or any exercise of, or failure to exercise, any rights or remedies
against the Borrower, any other Guarantor or any other Person or Property;

                      (f) any application of any sums by whomsoever paid or
howsoever realized to any obligation (other than the Obligations) of the
Borrower, regardless of what obligations of the Borrower remain unpaid;

                      (g) any invalidity or unenforceability relating to or
against the Borrower or any other Guarantor for any reason of this Agreement or
of any other Credit Document or any provision of applicable law or regulation
purporting to prohibit the payment by the Borrower or any other Guarantor of the
principal of or interest on any Note or any other amount payable by it under the
Credit Documents; or

                      (h) any other act or omission to act or delay of any kind
by the Agent, any Bank or any other Person or any other circumstance whatsoever
that might, but for the provisions of this paragraph, constitute a legal or
equitable discharge of the obligations of the Guarantor under this Section 13.

                13.3. Discharge Only Upon Payment in Full: Reinstatement in
Certain Circumstances. Each Guarantor's obligations under this Section 13 shall
remain in full force and effect until the Commitments are terminated and the
principal of and interest on the Notes and all other amounts payable by the
Borrower under this Agreement and all other Credit Documents shall have been
paid in full. If at any time any payment of the principal of or interest on any
Note or any other amount payable by the Borrower under the Credit Documents is
rescinded or must be otherwise restored or returned upon the insolvency,




                                       70

bankruptcy or reorganization of the Borrower or of a Guarantor, or otherwise,
each Guarantor's obligations under this Section 13 with respect to such payment
shall be reinstated at such time as though such payment had become due but had
not been made at such time.

         13.4   Waivers.

                (a) General. Each Guarantor irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as
well as any requirement that at any time any action be taken by the Agent, any
Bank or any other Person against the Borrower, another Guarantor or any other
Person.

                (b) Subrogation and Contribution. Each Guarantor hereby
irrevocably agrees that, until the Obligations have been paid in full, the
Commitments have been terminated and all Letters of Credit have terminated or
expired, it shall not exercise any claim or other right it may now or hereafter
acquire against the Borrower or any other Guarantor that arises from the
existence, payment, performance or enforcement of such Guarantor's obligations
under this Section 13 or any other Credit Document, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, or any right to participate in any claim or remedy of the
Agent, any Bank or any other holder of an Obligation against the Borrower or any
other Guarantor whether or not such claim, remedy or right arises in equity or
under contract, statute or common law, including without limitation, the right
to take or receive from the Borrower or any other Guarantor directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim or other right.

         13.5 Limit on Recovery. Notwithstanding any other provision hereof, the
right to recovery of the holders of the Obligations against each Guarantor under
this Section 13 shall not exceed $1.00 less than the amount which would render
such Guarantor's obligations under this Section 13 void or voidable under
applicable law, including without limitation fraudulent conveyance law.

         13.6 Stay of Acceleration. If acceleration of the time for payment of
any amount payable by the Borrower under this Agreement or any other Credit
Document is stayed upon the insolvency, bankruptcy or reorganization of the
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement or the other Credit Documents shall nonetheless be payable
jointly and severally by the Guarantors hereunder forthwith on demand by the
Agent made at the request of the Required Banks.

         14.    Miscellaneous.

                14.1. Withholding Taxes.

                      (a) Payments Free of Withholding. Except as otherwise
required by law and subject to Section 14.1(b) hereof, each payment by the
Borrower and each Guarantor under this Agreement or the other Credit Documents
shall be made without withholding for or on account of any present or future
taxes (other than overall net income taxes on the recipient) imposed by or
within the jurisdiction in which the Borrower or such Guarantor is domiciled,
any jurisdiction from which the Borrower or such Guarantor makes any payment, or
(in each case) any political subdivision or taxing authority thereof or therein.
If any such withholding is so required, the Borrower or relevant Guarantor shall
make the withholding, pay the amount withheld to the appropriate governmental
authority before penalties attach thereto or interest accrues thereon and
forthwith pay such additional amount as may be necessary to ensure that the net
amount actually received by each Bank and the Agent free and clear of such taxes
(including such taxes on such additional amount) is equal to the amount which
that Bank or the Agent (as the case may be) would have received had such
withholding not been made. If the Agent or any Bank pays any amount in respect
of any such taxes, penalties or interest the Borrower shall reimburse the Agent
or that Bank for that payment on demand in the currency in which such payment
was made. If the Borrower or any Guarantor pays any such taxes, penalties or
interest, it shall deliver official tax receipts evidencing that payment or
certified copies thereof to the Bank or Agent on whose account such withholding
was made (with a copy to the Agent if not the recipient of the original) on or
before the thirtieth day after payment. If any Bank or the Agent determines it
has received or been granted a credit against or relief or remission for, or
repayment of, any taxes paid or payable by it because of any taxes, penalties or
interest paid by the Borrower or any Guarantor and evidenced by such a tax
receipt, such Bank or Agent shall, to the extent it can do so without prejudice
to the retention of the amount of such credit, relief, remission or repayment,
pay to the Borrower or such Guarantor as applicable, such amount as such Bank or
Agent determines is attributable to such deduction or withholding and which will
leave such Bank or Agent (after such payment) in no better or worse position
than it would have been in if the Borrower had not been required to make such
deduction or withholding. Nothing in this Agreement shall interfere with the
right of each Bank and the Agent to arrange its tax affairs in whatever manner
it thinks fit nor oblige any Bank or the Agent to disclose any information
relating to its tax affairs or any computations in connection with such taxes.



                                       72
<PAGE>   80


                      (b) U.S. Withholding Tax Exemptions. Each Bank that is not
a United States person (as such term is defined in Section 7701(a)(30) of the
Code) shall submit to the Borrower and the Agent on or before the earlier of the
date the initial Borrowing is made hereunder and thirty (30) days after the date
hereof, two duly completed and signed copies of either Form 1001 (relating to
such Bank and entitling it to a complete exemption from withholding under the
Code on all amounts to be received by such Bank, including fees, pursuant to the
Credit Documents and the Loans) or Form 4224 (relating to all amounts to be
received by such Bank, including fees, pursuant to the Credit Documents and the
Loans) of the United States Internal Revenue Service. Thereafter and from time
to time, each Bank shall submit to the Borrower and the Agent such additional
duly completed and signed copies of one or the other of such Forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may be (i) requested by the Borrower in a written
notice, directly or through the Agent, to such Bank and (ii) required under
then-current United States law or regulations to avoid or reduce United States
withholding taxes on payments in respect of all amounts to be received by such
Bank, including fees, pursuant to the Credit Documents or the Loans.
Notwithstanding any provision of this Agreement to the contrary, the Borrower
shall not be required to make any payment under Section 14.1(a) to any Bank that
fails to comply with this Section 14.1(b) unless such failure is due to one of
the reasons specified in Section 14.1(c).

                      (c) Inability of Bank to Submit Forms. If any Bank
determines, as a result of any change in applicable law, regulation or treaty,
or in any official application or interpretation thereof, in each case after the
date hereof, that it is unable to submit to the Borrower or Agent any form or
certificate that such Bank is obligated to submit pursuant to subsection (b) of
this Section 14.1 or that such Bank is required to withdraw or cancel any such
form or certificate previously submitted or any such form or certificate
otherwise becomes ineffective or inaccurate, such Bank shall promptly notify the
Borrower and Agent of such fact (and the Bank shall to that extent not be
obligated to provide any such form or certificate and will be entitled to
withdraw or cancel any affected form or certificate, as applicable).

                      (d) If any Bank requests any payment under this Section
13, such Bank shall use reasonable efforts (consistent with its internal policy
and legal and regulatory restrictions) to designate a different Lending Office
if such designation would result in such Bank not requesting such payments.

                14.2. No Waiver of Rights. No delay or failure on the part of
the Agent or any Bank or on the part of the holder or holders of any Note in the




                                       73
<PAGE>   81

exercise of any power or right under any Credit Document shall operate as a
waiver thereof, nor as an acquiescence in any default, nor shall any single or
partial exercise thereof preclude any other or further exercise of any other
power or right, and the rights and remedies hereunder of the Agent, the Banks
and the holder or holders of any Notes are cumulative to, and not exclusive of,
any rights or remedies which any of them would otherwise have.

                14.3. Non-Business Day. If any payment of principal or interest
on any Loan or of any other Obligation shall fall due on a day which is not a
Business Day, interest or fees (as applicable) at the rate, if any, such Loan or
other Obligation bears for the period prior to maturity shall continue to accrue
on such Obligation from the stated due date thereof to and including the next
succeeding Business Day, on which the same shall be payable.

                14.4. Documentary Taxes. The Borrower agrees that it will pay
any documentary, stamp or similar taxes payable in respect to any Credit
Document, including interest and penalties, in the event any such taxes are
assessed, irrespective of when such assessment is made and whether or not any
credit is then in use or available hereunder.

                14.5. Survival of Representations. All representations and
warranties made herein or in certificates given pursuant hereto shall survive
the execution and delivery of this Agreement and the other Credit Documents, and
shall continue in full force and effect with respect to the date as of which
they were made as long as any credit is in use or available hereunder.

                14.6. Survival of Indemnities. All indemnities and all other
provisions relative to reimbursement to the Banks of amounts sufficient to
protect the yield of the Banks with respect to the Loans, including, but not
limited to, Section 3.6, Section 11.3 and Section 14.15 hereof, shall survive
the termination of this Agreement and the other Credit Documents and the payment
of the Loans and all other Obligations.

                14.7. Sharing of Set-Off. Each Bank agrees with each other Bank
a party hereto that if such Bank shall receive and retain any payment, whether
by set-off or application of deposit balances or otherwise ("Set-off'), on any
of the Loans or Reimbursement Obligations in excess of its ratable share of
payments on all such obligations then outstanding to the Banks, then such Bank
shall purchase for cash, at face value but without recourse, ratably from each
of the other Banks such amount of the Loans or Reimbursement Obligations, or
participations therein, held by each such other Banks (or interest therein) as
shall be necessary to cause such Bank to share such excess payment ratably with
all the other Banks;



                                       74
<PAGE>   82


provided, however, that if any such purchase is made by any Bank, and if such
excess payment or part thereof is thereafter recovered from such purchasing
Bank, the related purchases from the other Banks shall be rescinded ratably and
the purchase price restored as to the portion of such excess payment so
recovered, but without interest. For purposes of this Section 14.7, amounts owed
to or recovered by, the Agent in connection with Reimbursement Obligations in
which Banks have been required to fund their participation shall be treated as
amounts owed to or recovered by the Agent as a Bank hereunder.

                14.8. Notices. Except as otherwise specified herein, all notices
under the Credit Documents shall be in writing (including telecopy or other
electronic communication) and shall be given to a party hereunder at its address
or telecopier number set forth below or such other address or telecopier number
as such party may hereafter specify by notice to the Agent and the Borrower,
given by courier, by United States certified or registered mail, or by other
telecommunication device capable of creating a written record of such notice and
its receipt. Notices under the Credit Documents to the Banks and the Agent shall
be addressed to their respective addresses, telecopier or telephone numbers set
forth on the signature pages hereof, and to the Borrower and the Guarantors to:

                CLARCOR Inc.
                2323 Sixth Street
                P.O. Box 7007
                Rockford, Illinois 61125

                Telephone:  (815) 961-5717

                Each such notice, request or other communication shall be
effective (i) if given by telecopier, when such telecopy is transmitted to the
telecopier number specified in this Section 14.8 or on the signature pages
hereof and a confirmation of receipt of such telecopy has been received by the
sender, (ii) if given by courier, when delivered, (iii) if given by mail, three
Business Days after such communication is deposited in the mail, registered with
return receipt requested, addressed as aforesaid or (iv) if given by any other
means, when delivered at the addresses specified in this Section 14.8 or on the
signature pages hereof; provided that any notice given pursuant to Section 1 or
2 hereof shall be effective only upon receipt.

                14.9. Counterparts. This Agreement may be executed in any number
of counterpart signature pages, and by the different parties on different




                                       75
<PAGE>   83


counterparts, each of which when executed shall be deemed an original but all
such counterparts taken together shall constitute one and the same instrument.

                14.10. Successors and Assigns. This Agreement shall be binding
upon the Borrower and its successors and assigns, and shall inure to the benefit
of each of the Banks and the benefit of their respective successors and assigns,
including any subsequent holder of any Note. The Borrower may not assign any of
its rights or obligations under any Credit Document without the written consent
of all of the Banks.

                14.11. Participants. Each Bank shall have the right at its own
cost to grant participations (to be evidenced by one or more agreements or
certificates of participation) in the Loans made and Reimbursement Obligations
and/or Revolving Credit Commitments (and, if relevant, Swing Line Commitment)
held by such Bank at any time and from time to time to one or more other Persons
which constitute financial institutions, insurance companies or other commercial
lenders; provided that no such participation shall relieve any Bank of any of
its obligations under this Agreement, and, provided, further that no such
participant shall have any rights under this Agreement except as provided in
this Section 14.11, and the Agent shall have no obligation or responsibility to
such participant. Any agreement pursuant to which such participation is granted
shall provide that the granting Bank shall retain the sole right and
responsibility to enforce the obligations of the Borrower and Guarantors under
this Agreement and the other Credit Documents including, without limitation, the
right to approve any amendment, modification or waiver of any provision of the
Credit Documents, except that such agreement may provide that such Bank will not
agree to any modification, amendment or waiver of the Credit Documents that
would reduce the amount of or postpone any fixed date for payment of any
Obligation in which such participant has an interest. Any party to which such a
participation has been granted shall have the benefits of Section 3.6 and
Section 11.3 hereof; provided no participant shall be entitled to receive more
under such Sections than the Bank granting such participation would have
received had the participation not been granted. The Borrower and each Guarantor
authorizes each Bank to disclose to any participant or prospective participant
under this Section 14.11 or to any assignee or prospective assignee under
Section 14.12 hereof any financial or other information pertaining to the
Borrower or any Guarantor if such Bank has obtained the written agreement of
such participant, prospective participant, assignee or prospective assignee to
be bound by the provisions of Section 14.18 hereof.

                14.12. Assignment Agreements. Each Bank may, from time to time
upon at least five (5) Business Days' notice to the Agent, assign to financial
institutions, insurance companies or other commercial lenders or a Federal
Reserve




                                       76

Bank part of its rights and obligations under this Agreement (including without
limitation the indebtedness evidenced by the Notes then owned by such assigning
Bank, together with an equivalent proportion of its obligation to make loans and
advances and participate in Letters of Credit hereunder) pursuant to an
Assignment Agreement executed by the parties thereto, which shall specify in
each instance the portion of the indebtedness evidenced by the Notes which is to
be assigned to each such assignee lender and the portion of the Revolving Credit
Commitment (and, if relevant, Swing Line Commitment) of the assigning Bank to be
assumed by it; provided, however, that (i) except with respect to the Swing
Loans (which must be assigned in whole), each such assignment shall be of a
constant, and not a varying, percentage of the assigning Bank's rights and
obligations under this Agreement and the assignment shall cover the same
percentage of such Bank's Revolving Credit Commitment, Loans, Notes and
interests in Letters of Credit; (ii) unless the Agent and the Borrower otherwise
consent, the aggregate amount of the Revolving Credit Commitment, Loans, Notes
and interests in the Letters of Credit of the assigning Bank being assigned to
such assignee lender pursuant to each such assignment (determined as of the
effective date of the relevant Assignment Agreement) shall in no event be less
than $5,000,000 and shall be an integral multiple of $1,000,000; (iii) the Agent
and (except for an assignment made during the continuance of any Event of
Default) the Borrower must each consent, which consent shall not be unreasonably
withheld, to each such assignment to a party which was not an original signatory
of this Agreement or an Affiliate of such a signatory, and (iv) the assignee
lender must pay to the Agent a processing and recordation fee of $3,500 and any
out-of-pocket attorney's fees incurred by the Agent in connection with such
Assignment Agreement. Upon the execution of each Assignment Agreement by the
assigning Bank thereunder, the assignee lender thereunder, the Borrower and the
Agent and payment to such assigning Bank by such assignee lender of the purchase
price for the portion of the indebtedness of the Borrower being acquired by it,
(i) such assignee lender shall thereupon become a "Bank" for all purposes of
this Agreement with Revolving Credit Commitment (and, if relevant, shall be
deemed to be Firstar for purposes of the Swing Loans) in the amounts set forth
in such Assignment Agreement and with all the rights, powers and obligations
afforded a Bank hereunder, (ii) such assigning Bank shall have no further
liability for funding the portion of its Revolving Credit Commitment (and, if
relevant, Swing Line Commitment) assumed by such other Bank and (iii) the
address for notices to such assignee Bank shall be as specified in the
Assignment Agreement executed by it. Concurrently with the execution and
delivery of such Assignment Agreement, the Borrower shall execute and deliver
new Notes to the assignee Bank in the amount of its Revolving Credit Commitment
(and, if relevant, Swing Line Commitment) and new Notes to the assigning Bank in
the amounts of its Revolving Credit Commitment after giving effect to the
reduction occasioned



                                       77
<PAGE>   85


by such assignment, such Notes to constitute "Notes" for all purposes of this
Agreement.

                14.13. Amendments. Any provision of the Credit Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by (a) the Borrower, (b) the Required Banks, (c) if the rights or duties
of the Agent are affected thereby, the Agent; and (d) if the rights and duties
of the Issuing Bank are affected thereby, the Issuing Bank; provided that:

                       (i)  no amendment or waiver pursuant to this Section
14.13 shall (A) increase any Revolving Credit Commitment or Swing Line
Commitment of any Bank without the consent of such Bank or (B) reduce the amount
of or postpone any fixed date for payment of any principal of or interest on any
Loan or Reimbursement Obligation or of any fee payable hereunder without the
consent of each Bank; and

                       (ii) no amendment or waiver pursuant to this Section
14.13 shall, unless signed by each Bank, change any provision of Section 8.1,
this Section 14.13, or the definition of Required Banks, or affect the number of
Banks required to take any action under the Credit Documents.

                14.14. Headings. Section headings used in this Agreement are for
reference only and shall not affect the construction of this Agreement.

                14.15. Legal Fees, Other Costs and Indemnification. The Borrower
agrees to pay all reasonable costs and expenses of the Agent in connection with
the preparation, negotiation, associated due diligence review, administration
and syndication of the Credit Documents, including without limitation, the
reasonable fees and disbursements of Reinhart, Boerner, Van Deuren, Norris &
Rieselbach, s.c., counsel to the Agent, in connection with the preparation and
execution of the Credit Documents, and any amendment waiver or consent related
hereto, whether or not the transactions contemplated herein are consummated.
Notwithstanding anything in the foregoing to the contrary, the Borrower shall
not be liable, without its consent, for more than $35,000 of the legal fees
(exclusive of disbursements and separately charged items) of Reinhart, Boerner,
Van Deuren, Norris & Rieselbach, s.c., counsel to the Agent, in connection with
the preparation, negotiation and execution of this Agreement and the other
Credit Documents delivered prior to the initial Credit Event. The Borrower
further agrees to indemnify each Bank, the Agent, and their respective
directors, officers and employees, against all losses, claims, damages,
penalties, judgments, liabilities and expenses (including, without limitation,
all expenses of litigation or preparation therefor, whether or not the
indemnified Person is a party thereto) which any of



                                       78
<PAGE>   86


them may incur or reasonably pay arising out of or relating to any Credit
Document or any of the transactions contemplated thereby or the direct or
indirect application or proposed application of the proceeds of any Loan or
Letter of Credit, other than those which arise from the gross negligence or
willful misconduct of the party claiming indemnification; provided, however,
that notwithstanding the foregoing, the Borrower shall not be obligated to
indemnify any such Person for any loss, claim, damage, penalty, judgment,
liability or expense arising solely from (i) a dispute between two or more Banks
or (ii) a claim by any Bank against the Borrower, or by the Borrower against any
Bank, that is found in a final, nonappealable judgment by a court of competent
jurisdiction in favor of the Borrower (it being understood that this clause (ii)
shall affect or limit any amount the Borrower may owe to any Bank as a result of
any such claim under the first sentence of this Section 14.15). The Borrower,
upon demand by the Agent or a Bank at any time, shall reimburse the Agent or
Bank for any reasonable legal or other expenses incurred in connection with
investigating or defending against any of the foregoing except if the same is
directly due to the gross negligence or willful misconduct of the party to be
indemnified as determined by a final, nonappealable judgment of a court of
competant jurisdiction.

                14.16. Set Off. In addition to any rights now or hereafter
granted under applicable law and not by way of limitation of any such rights,
upon the occurrence of any Event of Default, each Bank and each subsequent
holder of any Note is hereby authorized by the Borrower and each Guarantor at
any time or from time to time, without notice to the Borrower, to the Guarantors
or to any other Person, any such notice being hereby expressly waived, to set
off and to appropriate and to apply any and all deposits (general or special,
including, but not limited to, Indebtedness evidenced by certificates of
deposit, whether matured or unmatured, but not including trust accounts, and in
whatever currency denominated) and any other Indebtedness at any time held or
owing by that Bank or that subsequent holder to or for the credit or the account
of the Borrower or any Guarantor, whether or not matured, against and on account
of the obligations and liabilities of the Borrower or any Guarantor to that Bank
or that subsequent holder under the Credit Documents, including, but not limited
to, all claims of any nature or description arising out of or connected with the
Credit Documents, irrespective of whether or not (a) that Bank or that
subsequent holder shall have made any demand hereunder or (b) the principal of
or the interest on the Loans or Notes and other amounts due hereunder shall have
become due and payable pursuant to Section 10 and although said obligations and
liabilities, or any of them, may be contingent or unmatured.

                14.17. Currency. Each reference in this Agreement to U.S.
Dollars or to an Alternative Currency (the "relevant currency") is of the
essence. To the



                                       79
<PAGE>   87


fullest extent permitted by law, the obligation of the Borrower and each
Guarantor in respect of any amount due in the relevant currency under this
Agreement shall, notwithstanding any payment in any other currency (whether
pursuant to a judgment or otherwise), be discharged only to the extent of the
amount in the relevant currency that the Person entitled to receive such payment
may, in accordance with normal banking procedures, purchase with the sum paid in
such other currency (after any premium and costs of exchange) on the Business
Day immediately following the day on which such Person receives such payment. If
the amount of the relevant currency so purchased is less than the sum originally
due to such Person in the relevant currency, the Borrower or relevant Guarantor
agrees, as a separate obligation and notwithstanding any such judgment, to
indemnify such Person against such loss, and if the amount of the specified
currency so purchased exceeds the sum of (a) the amount originally due to the
relevant Person in the specified currency plus (b) any amounts shared with other
Banks as a result of allocations of such excess as a disproportionate payment to
such Person under Section 14.7 hereof, such Person agrees to remit such excess
to the Borrower.

                14.18. Confidentiality. Neither the Agent nor any Bank shall
disclose any Confidential Information to any Person without the prior written
consent of the Borrower other than (a) to the Agent's or such Bank's Affiliates
and their officers, directors, employees, agent and advisors, (b) to actual or
prospective assignees and participants and then only on a confidential basis,
(c) as required by any law, rule or regulation or judicial or legal process,
provided that solely with respect to this clause (c) the Agent or such Bank
shall notify the Borrower of the requirement or request that it disclose any
such Confidential Information prior to doing so unless such notification is
prohibited by any applicable law or judicial or legal process, (d) to the Agent
and/or other Banks and (e) as requested or required by any state, federal or
foreign authority or examiner regulating banks or banking.

                14.19. Entire Agreement. The Credit Documents constitute the
entire understanding of the parties thereto with respect to the subject matter
thereof and any prior or contemporaneous agreements, whether written or oral,
with respect thereto are superseded thereby.

                14.20. Governing Law. This Agreement and the other Credit
Documents, and the rights and duties of the parties hereto, shall be construed
and determined in accordance with the internal laws of the State of Wisconsin.

                14.21. Submission to Jurisdiction: Waiver of Jury Trial. The
Borrower, each Guarantor, the Agent and each Bank hereby submits to the
nonexclusive jurisdiction of the United States District Court for the Eastern




                                       80
<PAGE>   88


District of Wisconsin and of any Wisconsin State court sitting in the City of
Milwaukee for purposes of all legal proceedings arising out of or relating to
this Agreement, the other Credit Documents or the transactions contemplated
hereby or thereby. The Borrower, each Guarantor, the Agent and each Bank
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 proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient forum. THE BORROWER, EACH GUARANTOR,
THE AGENT AND EACH BANK HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT
OR THE TRANSACTIONS CONTEMPLATED THEREBY.

FOR IMMEDIATE RELEASE
MONDAY, SEPTEMBER 13, 1999


                  CLARCOR TO ACQUIRE THREE FILTRATION COMPANIES
                   ACQUISITIONS WILL INCREASE REVENUES BY 35%


ROCKFORD, IL, SEPTEMBER 13, 1999 - CLARCOR INC. (NYSE: CLC) today announced that
it has signed a definitive agreement to acquire, effective September 1, 1999,
three filtration businesses from Mark IV Industries. The companies are:
PUROLATOR PRODUCTS AIR FILTRATION COMPANY, FACET INTERNATIONAL and
PUROLATOR-FACET FILTER PRODUCTS.

The purchase price for the three companies is approximately $136 million. No
debt was assumed. The transaction is structured primarily as an acquisition of
assets and will provide CLARCOR with deductible goodwill having a net present
value tax benefit to CLARCOR of more than $11 million. In the most recently
completed fiscal year for the three companies, sales totaled $150 million and
will increase CLARCOR's sales by approximately 35%. For the year ended November
30, 1998, CLARCOR had net sales of $427 million.

"This is a significant opportunity for CLARCOR. By acquiring three quality
businesses, it will increase our total sales by approximately 35% in the first
year," said Larry Gloyd, CLARCOR's Chairman and CEO. "These are good businesses
with solid margins, and although we expect the acquisitions to be $0.01-$0.02
dilutive to diluted earnings per share in fiscal 2000, they should be accretive
thereafter. Looking ahead, we see the potential for further improvement in sales
and margins, plus attractive returns on invested capital."

Gloyd emphasized, "These acquisitions fit well with our strategy to provide our
customers with their complete filter requirements, including supply,
installation and service, for all types of manufacturing plants, distribution
centers, retail stores, office facilities and engine applications. These
companies will add new types of filtration products and systems to our product
lines with recognized brand names and give us access to new markets and
customers, particularly in the aviation and fluid processing industries. They
will also increase our manufacturing leverage, which will enable us to reduce
costs and improve margins. In conclusion, this acquisition will significantly
strengthen CLARCOR and our presence in the filtration marketplace."

Purolator Products Air Filtration Company (PPAFC) is a manufacturer of a wide
range of air filters used in heating, ventilation and air conditioning systems.
PPAFC is based in Henderson, North Carolina, with two manufacturing sites in
North Carolina, one in Iowa and one in California. PPAFC will add to CLARCOR's
Industrial/Environmental air filtration manufacturing capabilities and provide
opportunities for improved operating efficiencies.
