Period. Subject to the terms of Section 2.6, the Borrower may elect from time to
time to convert all or any part of a Floating Rate Advance into a Eurodollar
Advance. The Borrower shall give the Agent irrevocable notice (a
"Conversion/Continuation Notice") of each conversion of a Floating Rate Advance
into a Eurodollar Advance or continuation of a Eurodollar Advance not later than
10:00 a.m. (Detroit time) at least three Business Days prior to the date of the
requested conversion or continuation, specifying:

      (i)      the requested date, which shall be a Business Day, of such
               conversion or continuation,

      (ii)     the aggregate amount and Type of the Advance which is to be
               converted or continued, and

      (iii)    the amount of such Advance which is to be converted into or
               continued as a Eurodollar Advance and the duration of the
               Interest Period applicable thereto.



<PAGE>   18


        2.10.  Changes in Interest Rate, etc. Each Floating Rate Advance shall
bear interest on the outstanding principal amount thereof, for each day from and
including the date such Advance is made or is automatically converted from a
Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.9, to but
excluding the date it is paid or is converted into a Eurodollar Advance pursuant
to Section 2.9 hereof, at a rate per annum equal to the Floating Rate for such
day. Changes in the rate of interest on that portion of any Advance maintained
as a Floating Rate Advance will take effect simultaneously with each change in
the Alternate Prime Rate. Each Eurodollar Advance shall bear interest on the
outstanding principal amount thereof from and including the first day of the
Interest Period applicable thereto to (but not including) the last day of such
Interest Period at the interest rate determined by the Agent as applicable to
such Eurodollar Advance based upon the Borrower's selections under Sections 2.8
and 2.9 and otherwise in accordance with the terms hereof. No Interest Period
may end after the Facility Termination Date.

        2.11.  Rates Applicable After Default. Notwithstanding anything to the
contrary contained in Section 2.8 or 2.9, during the continuance of a Default or
Unmatured Default the Required Lenders may, at their option, by notice to the
Borrower (which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of Section 8.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that no Advance may be made as,
converted into or continued as a Eurodollar Advance. During the continuance of a
Default the Required Lenders may, at their option, by notice to the Borrower
(which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of Section 8.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that (i) each Eurodollar Advance
shall bear interest for the remainder of the applicable Interest Period at the
rate otherwise applicable to such Interest Period plus 2% per annum, (ii) each
Floating Rate Advance and Swing Loan shall bear interest at a rate per annum
equal to the Floating Rate in effect from time to time plus 2% per annum and
(iii) the LC Fee shall be increased by 2% per annum, provided that, during the
continuance of a Default under Section 7.6 or 7.7, the interest rates set forth
in clauses (i) and (ii) above and the increase in the LC Fee set forth in clause
(iii) above shall be applicable to all Credit Extensions without any election or
action on the part of the Agent or any Lender.

        2.12.  Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Agent at the Agent's address specified pursuant to
Article XIII, or at any other Lending Installation of the Agent specified in
writing by the Agent to the Borrower, by noon (Detroit time) on the date when
due and shall (except in the case of Reimbursement Obligations for which the LC
Issuer has not been fully indemnified by the Lenders, or as otherwise
specifically required hereunder) be applied ratably by the Agent among the
Lenders. Each payment delivered to the Agent for the account of any Lender shall
be delivered promptly by the Agent to such Lender in the same type of funds that
the Agent received at its address specified pursuant to Article XIII or at any
Lending Installation specified in a notice received by the Agent from such
Lender. The Agent is hereby authorized to charge the account of the Borrower
maintained with Bank One or any of its Affiliates for each payment of principal,
interest, Reimbursement Obligations and fees as it becomes due hereunder. Each
reference to the Agent in this Section 2.12 shall also be deemed to refer, and
shall apply equally, to the LC Issuer, in the case of payments required to be
made by the Borrower to the LC Issuer pursuant to Section 2.19.6.

        2.13.  Noteless Agreement; Evidence of Indebtedness. (i) Each Lender
shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

        (ii)   The Agent shall also maintain accounts in which it will record
(a) the amount of each Loan made hereunder, the Type thereof and the Interest
Period with respect thereto, (b) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder,
(c) the original stated amount of each Facility LC and the amount of LC
Obligations outstanding at any time, and (d) the amount of any sum received by
the Agent hereunder from the Borrower and each Lender's share thereof.



<PAGE>   19



        (iii)  The entries maintained in the accounts maintained pursuant to
paragraphs (i) and (ii) above shall be prima facie evidence of the existence and
amounts of the Obligations therein recorded; provided, however, that the failure
of the Agent or any Lender to maintain such accounts or any error therein shall
not in any manner affect the obligation of the Borrower to repay the Obligations
in accordance with their terms.

        (iv)   Any Lender may request that its Loans be evidenced by a
promissory note (a "Note"). In such event, the Borrower shall prepare, execute
and deliver to such Lender a Note payable to the order of such Lender in a form
supplied by the Agent. Thereafter, the Loans evidenced by such Note and interest
thereon shall at all times (including after any assignment pursuant to Section
12.3) be represented by one or more Notes payable to the order of the payee
named therein or any assignee pursuant to Section 12.3, except to the extent
that any such Lender or assignee subsequently returns any such Note for
cancellation and requests that such Loans once again be evidenced as described
in paragraphs (i) and (ii) above.

        2.14.  Telephonic Notices. The Borrower hereby authorizes the Lenders
and the Agent to extend, convert or continue Advances, effect selections of
Types of Advances and to transfer funds based on telephonic notices made by any
person or persons the Agent or any Lender in good faith believes to be acting on
behalf of the Borrower, it being understood that the foregoing authorization is
specifically intended to allow Borrowing Notices and Conversion/Continuation
Notices to be given telephonically. The Borrower agrees to deliver promptly to
the Agent a written confirmation, if such confirmation is requested by the Agent
or any Lender, of each telephonic notice signed by an Authorized Officer. If the
written confirmation differs in any material respect from the action taken by
the Agent and the Lenders, the records of the Agent and the Lenders shall govern
absent manifest error.

        2.15.  Interest Payment Dates; Interest and Fee Basis. Interest accrued
on each Floating Rate Advance shall be payable on each Payment Date, commencing
with the first such date to occur after the date hereof, on any date on which
the Floating Rate Advance is prepaid, whether due to acceleration or otherwise,
and at maturity. Interest accrued on that portion of the outstanding principal
amount of any Floating Rate Advance converted into a Eurodollar Advance on a day
other than a Payment Date shall be payable on the date of conversion. Interest
accrued on each Eurodollar Advance shall be payable on the last day of its
applicable Interest Period, on any date on which the Eurodollar Advance is
prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued
on each Eurodollar Advance having an Interest Period longer than three months
shall also be payable on the last day of each three-month interval during such
Interest Period. Interest, commitment fees and LC Fees shall be calculated for
actual days elapsed on the basis of a 360-day year. Interest shall be payable
for the day an Advance is made but not for the day of any payment on the amount
paid if payment is received prior to noon (local time) at the place of payment.
If any payment of principal of or interest on an Advance shall become due on a
day which is not a Business Day, such payment shall be made on the next
succeeding Business Day and, in the case of a principal payment, such extension
of time shall be included in computing interest in connection with such payment.

        2.16.  Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions. Promptly after receipt thereof, the Agent will notify
each Lender of the contents of each Aggregate Commitment reduction notice,
Borrowing Notice, Conversion/Continuation Notice, and repayment notice received
by it hereunder. Promptly after notice from the LC Issuer, the Agent will notify
each Lender of the contents of each request for issuance of a Facility LC
hereunder. The Agent will notify each Lender of the interest rate applicable to
each Eurodollar Advance promptly upon determination of such interest rate and
will give each Lender prompt notice of each change in the Alternate Prime Rate.

        2.17.  Lending Installations. Each Lender may book its Loans and its
participation in any LC Obligations and Swing Loans, the Agent may book the
Swing Loans and the LC Issuer may book the Facility LCs at any Lending
Installation selected by such Lender, the Agent or the LC Issuer, as the case
may be, and may change its Lending Installation from time to time. All terms of
this Agreement shall apply to any such Lending Installation and the Loans,
Facility LCs, participations in LC Obligations and Swing Loans and any Notes
issued hereunder shall be deemed held by each Lender or the LC Issuer, as the
case may be, for the benefit of any such Lending Installation. Each Lender and
the LC





<PAGE>   20


Issuer may, by written notice to the Agent and the Borrower in accordance
with Article XIII, designate replacement or additional Lending Installations
through which Loans will be made by it or Facility LCs will be issued by it and
for whose account Loan payments or payments with respect to Facility LCs and
Swing Loans are to be made.

        2.18.  Non-Receipt of Funds by the Agent. Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made. The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption. If
such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to (x) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day for the first three days and,
thereafter, the interest rate applicable to the relevant Loan or (y) in the case
of payment by the Borrower, the interest rate applicable to the relevant Loan.

        2.19.  Facility LCs.

                2.19.1. Issuance. The LC Issuer hereby agrees, on the terms and
        conditions set forth in this Agreement, to issue standby and commercial
        letters of credit (each, a "Facility LC") and to renew, extend,
        increase, decrease or otherwise modify each Facility LC ("Modify," and
        each such action a "Modification"), from time to time from and including
        the date of this Agreement and prior to the Facility Termination Date
        upon the request of the Borrower; provided that immediately after each
        such Facility LC is issued or Modified, (i) the aggregate amount of the
        outstanding LC Obligations shall not exceed $5,000,000 and (ii) the
        Aggregate Outstanding Credit Exposure shall not exceed the Aggregate
        Commitment. No Facility LC shall have an expiry date later than the
        earlier of (x) the date one month prior to the then known Facility
        Termination Date and (y) one year after its issuance.

                2.19.2. Participations. Upon the issuance or Modification by the
        LC Issuer of a Facility LC in accordance with this Section 2.19, the LC
        Issuer shall be deemed, without further action by any party hereto, to
        have absolutely, automatically, unconditionally and irrevocably sold to
        each Lender, and each Lender shall be deemed, without further action by
        any party hereto, to have absolutely, automatically, unconditionally and
        irrevocably purchased from the LC Issuer, a participation in such
        Facility LC (and each Modification thereof) and the related LC
        Obligations in proportion to its Pro Rata Share.

                2.19.3. Notice. Subject to Section 2.19.1, the Borrower shall
        give the LC Issuer notice prior to 10:00 a.m. (Detroit time) at least
        five Business Days (or such lesser period as agreed to by the LC Issuer)
        prior to the proposed date of issuance or Modification of each Facility
        LC, specifying the beneficiary, the proposed date of issuance (or
        Modification) and the expiry date of such Facility LC, and describing
        the proposed terms of such Facility LC and the nature of the
        transactions proposed to be supported thereby. Upon receipt of such
        notice, the LC Issuer shall promptly notify the Agent, and the Agent
        shall promptly notify each Lender, of the contents thereof and of the
        amount of such Lender's participation in such proposed Facility LC. The
        issuance or Modification by the LC Issuer of any Facility LC shall, in
        addition to the conditions precedent set forth in Article IV (the
        satisfaction of which the LC Issuer shall have no duty to ascertain), be
        subject to the conditions precedent that such Facility LC shall be
        satisfactory to the LC Issuer and that the Borrower shall have executed
        and delivered such application agreement and/or such other instruments
        and agreements relating to such Facility LC as the LC Issuer shall have
        reasonably requested (each, a "Facility LC Application"). In the event
        of any conflict between the terms of this Agreement and the terms of any
        Facility LC Application, the terms of this Agreement shall control.




<PAGE>   21


                2.19.4. LC Fees. The Borrower shall pay to the Agent, for the
        account of the Lenders ratably in accordance with their respective Pro
        Rata Shares, with respect to each Facility LC, a letter of credit fee at
        a per annum rate equal to the Applicable Margin for Eurodollar Loans in
        effect from time to time on the average daily undrawn stated amount
        under such standby Facility LC, such fee to be payable in arrears on
        each Payment Date, (each such fee described in this sentence an "LC
        Fee"). The Borrower shall also pay to the LC Issuer for its own account
        (x) at the time of issuance of each Facility LC, a fronting fee in an
        amount equal to 0.25% per annum on the average daily undrawn stated
        amount under each Facility LC, and (y) documentary and processing
        charges in connection with the issuance or Modification of and draws
        under Facility LCs in accordance with the LC Issuer's standard schedule
        for such charges as in effect from time to time.

                2.19.5. Administration; Reimbursement by Lenders. Upon receipt
        from the beneficiary of any Facility LC of any demand for payment under
        such Facility LC, the LC Issuer shall notify the Agent and the Agent
        shall promptly notify the Borrower and each other Lender as to the
        amount to be paid by the LC Issuer as a result of such demand and the
        proposed payment date (the "LC Payment Date"). The responsibility of the
        LC Issuer to the Borrower and each Lender shall be only to determine
        that the documents (including each demand for payment) delivered under
        each Facility LC in connection with such presentment shall be in
        conformity in all material respects with such Facility LC. The LC Issuer
        shall endeavor to exercise the same care in the issuance and
        administration of the Facility LCs as it does with respect to letters of
        credit in which no participations are granted, it being understood that
        in the absence of any gross negligence or willful misconduct by the LC
        Issuer, each Lender shall be absolutely, unconditionally and irrevocably
        liable (and such obligation shall not be affected by any circumstance,
        including, without limitation, (A) any set-off, counterclaim,
        recoupment, defense or other right which such Lender has or may have
        against the LC Issuer, the Agent or the Borrower or any if its
        Subsidiaries or anyone else for any reason whatsoever; (B) the
        occurrence or continuance of an Unmatured Default or a Default; (C) any
        adverse change in the condition (financial or otherwise) of the Borrower
        or any of its Subsidiaries or any other Guarantor; (D) any breach of
        this Agreement or any other Loan Document by any other Lender, the
        Borrower or any Guarantor; or (E) any other circumstance, happening or
        event whatsoever, whether or not similar to any of the foregoing
        ,including without limitation the Borrower's failure to satisfy any
        conditions contained in Article IV or any other provision of this
        Agreement) to reimburse the LC Issuer on demand for (i) such Lender's
        Pro Rata Share of the amount of each payment made by the LC Issuer under
        each Facility LC to the extent such amount is not reimbursed by the
        Borrower pursuant to Section 2.19.6 below, plus (ii) interest on the
        foregoing amount to be reimbursed by such Lender, for each day from the
        date of the LC Issuer's demand for such reimbursement (or, if such
        demand is made after 11:00 a.m. (Detroit time) on such date, from the
        next succeeding Business Day) to the date on which such Lender pays the
        amount to be reimbursed by it, at a rate of interest per annum equal to
        the Federal Funds Effective Rate for the first three days and,
        thereafter, at a rate of interest equal to the rate applicable to
        Floating Rate Advances.

                2.19.6. Reimbursement by Borrower. The Borrower shall be
        irrevocably and unconditionally obligated to reimburse the LC Issuer on
        or before the later of (x) the applicable LC Payment Date and (y) the
        date on which the Borrower shall have received the related notice from
        the Agent under Section 2.19.5 for any amounts to be paid by the LC
        Issuer upon any drawing under any Facility LC, without presentment,
        demand, protest or other formalities of any kind; provided that neither
        the Borrower nor any Lender shall hereby be precluded from asserting any
        claim for direct (but not consequential) damages suffered by the
        Borrower or such Lender to the extent, but only to the extent, caused by
        (i) the willful misconduct or gross negligence of the LC Issuer in
        determining whether a request presented under any Facility LC issued by
        it complied with the terms of such Facility LC or (ii) the LC Issuer's
        failure to pay under any Facility LC issued by it after the presentation
        to it of a request strictly complying with the terms and conditions of
        such Facility LC. All such amounts paid by the LC Issuer and remaining
        unpaid by the Borrower shall bear interest, payable on demand, for each
        day from the later of (x) the applicable LC Payment Date and (y) the
        date on which the Borrower shall have received the related notice from
        the Agent under Section 2.19.5 until paid at a rate per annum equal to
        (x) the rate applicable to Floating Rate Advances for such day if such
        day falls on or before the applicable LC Payment Date and (y) the sum of
        2% plus the rate applicable to Floating



<PAGE>   22

        Rate Advances for such day if such day falls after such LC Payment Date.
        The LC Issuer will pay to each Lender ratably in accordance with its Pro
        Rata Share all amounts received by it from the Borrower for application
        in payment, in whole or in part, of the Reimbursement Obligation in
        respect of any Facility LC issued by the LC Issuer, but only to the
        extent such Lender has made payment to the LC Issuer in respect of such
        Facility LC pursuant to Section 2.19.5. Subject to the terms and
        conditions of this Agreement (including without limitation the
        submission of a Borrowing Notice in compliance with Section 2.8 and the
        satisfaction of the applicable conditions precedent set forth in Article
        IV), the Borrower may request an Advance hereunder for the purpose of
        satisfying any Reimbursement Obligation.

                2.19.7. Obligations Absolute. The Borrower's obligations under
        this Section 2.19 shall be absolute and unconditional under any and all
        circumstances and irrespective of any setoff, counterclaim or defense to
        payment which the Borrower may have or have had against the LC Issuer,
        any Lender or any beneficiary of a Facility LC. The Borrower further
        agrees with the LC Issuer and the Lenders that the LC Issuer and the
        Lenders shall not be responsible for, and the Borrower's Reimbursement
        Obligation in respect of any Facility LC shall not be affected by, among
        other things, the validity or genuineness of documents or of any
        endorsements thereon, even if such documents should in fact prove to be
        in any or all respects invalid, fraudulent or forged, or any dispute
        between or among the Borrower, any of its Affiliates, the beneficiary of
        any Facility LC or any financing institution or other party to whom any
        Facility LC may be transferred or any claims or defenses whatsoever of
        the Borrower or of any of its Affiliates against the beneficiary of any
        Facility LC or any such transferee. The LC Issuer shall not be liable
        for any error, omission, interruption or delay in transmission, dispatch
        or delivery of any message or advice, however transmitted, in connection
        with any Facility LC. The Borrower agrees that any action taken or
        omitted by the LC Issuer or any Lender under or in connection with each
        Facility LC and the related drafts and documents, if done without gross
        negligence or willful misconduct, shall be binding upon the Borrower and
        shall not put the LC Issuer or any Lender under any liability to the
        Borrower. Nothing in this Section 2.19.7 is intended to limit the right
        of the Borrower to make a claim against the LC Issuer for damages as
        contemplated by the proviso to the first sentence of Section 2.19.6.

                2.19.8. Actions of LC Issuer. The LC Issuer shall be entitled to
        rely, and shall be fully protected in relying, upon any Facility LC,
        draft, writing, resolution, notice, consent, certificate, affidavit,
        letter, cablegram, telegram, telecopy, telex or teletype message,
        statement, order or other document believed by it to be genuine and
        correct and to have been signed, sent or made by the proper Person or
        Persons, and upon advice and statements of legal counsel, independent
        accountants and other experts selected by the LC Issuer. The LC Issuer
        shall be fully justified in failing or refusing to take any action under
        this Agreement unless it shall first have received such advice or
        concurrence of the Required Lenders as it reasonably deems appropriate
        or it shall first be indemnified to its reasonable satisfaction by the
        Lenders against any and all liability and expense which may be incurred
        by it by reason of taking or continuing to take any such action.
        Notwithstanding any other provision of this Section 2.19, the LC Issuer
        shall in all cases be fully protected in acting, or in refraining from
        acting, under this Agreement in accordance with a request of the
        Required Lenders, and such request and any action taken or failure to
        act pursuant thereto shall be binding upon the Lenders and any future
        holders of a participation in any Facility LC.

                2.19.9. Indemnification. The Borrower hereby agrees to indemnify
        and hold harmless each Lender, the LC Issuer and the Agent, and their
        respective directors, officers, agents and employees from and against
        any and all claims and damages, losses, liabilities, costs or expenses
        which such Lender, the LC Issuer or the Agent may incur (or which may be
        claimed against such Lender, the LC Issuer or the Agent by any Person
        whatsoever) by reason of or in connection with the issuance, execution
        and delivery or transfer of or payment or failure to pay under any
        Facility LC or any actual or proposed use of any Facility LC, including,
        without limitation, any claims, damages, losses, liabilities, costs or
        expenses which the LC Issuer may incur by reason of or in connection
        with (i) the failure of any other Lender to fulfill or comply with its
        obligations to the LC Issuer hereunder (but nothing herein contained
        shall affect any rights the Borrower may have against any Defaulting
        Lender) or (ii) by reason of or on account of the LC Issuer issuing any
        Facility LC which specifies that the term "Beneficiary" included therein




<PAGE>   23


        includes any successor by operation of law of the named Beneficiary, but
        which Facility LC does not require that any drawing by any such
        successor Beneficiary be accompanied by a copy of a legal document,
        reasonably satisfactory to the LC Issuer, evidencing the appointment of
        such successor Beneficiary; provided that the Borrower shall not be
        required to indemnify any Lender, the LC Issuer or the Agent for any
        claims, damages, losses, liabilities, costs or expenses to the extent,
        but only to the extent, caused by (x) the willful misconduct or gross
        negligence of the LC Issuer in determining whether a request presented
        under any Facility LC complied with the terms of such Facility LC or (y)
        the LC Issuer's failure to pay under any Facility LC after the
        presentation to it of a request strictly complying with the terms and
        conditions of such Facility LC. Nothing in this Section 2.19.9 is
        intended to limit the obligations of the Borrower under any other
        provision of this Agreement or of any Lender against another Lender.

                2.19.10. Lenders' Indemnification. Each Lender shall, ratably in
        accordance with its Pro Rata Share, indemnify the LC Issuer, its
        affiliates and their respective directors, officers, agents and
        employees (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
        such indemnitees' gross negligence or willful misconduct or the LC
        Issuer's failure to pay under any Facility LC after the presentation to
        it of a request strictly complying with the terms and conditions of the
        Facility LC) that such indemnitees may suffer or incur in connection
        with this Section 2.19 or any action taken or omitted by such
        indemnitees hereunder.

                2.19.11. Facility LC Collateral Account. The Borrower agrees
        that it will, upon the request of the Agent or the Required Lenders and
        until the final expiration date of any Facility LC and thereafter as
        long as any amount is payable to the LC Issuer or the Lenders in respect
        of any Facility LC, maintain a special collateral account pursuant to
        arrangements satisfactory to the Agent (the "Facility LC Collateral
        Account") at the Agent's office at the address specified pursuant to
        Article XIII, in the name of such Borrower but under the sole dominion
        and control of the Agent, for the benefit of the Lenders and in which
        such Borrower shall have no interest other than as set forth in Section
        8.1. The Borrower hereby pledges, assigns and grants to the Agent, on
        behalf of and for the ratable benefit of the Lenders and the LC Issuer,
        a security interest in all of the Borrower's right, title and interest
        in and to all funds which may from time to time be on deposit in the
        Facility LC Collateral Account to secure the prompt and complete payment
        and performance of the Obligations. The Agent will invest any funds on
        deposit from time to time in the Facility LC Collateral Account in
        certificates of deposit of Bank One having a maturity not exceeding 30
        days. Nothing in this Section 2.19.11 shall either obligate the Agent to
        require the Borrower until after a Default to deposit any funds in the
        Facility LC Collateral Account or limit the right of the Agent to
        release any funds held in the Facility LC Collateral Account in each
        case other than as required by Section 8.1.

                2.19.12. Rights as a Lender. In its capacity as a Lender, the LC
        Issuer shall have the same rights and obligations as any other Lender.

        2.20   Swing Loans.

                2.20.1. MAKING OF SWING LOANS. THE AGENT MAY ELECT IN ITS SOLE
        DISCRETION TO MAKE LOANS (THE "SWING LOANS") TO THE BORROWER FROM TIME
        TO TIME PRIOR TO THE FACILITY TERMINATION DATE; PROVIDED THAT
        IMMEDIATELY AFTER EACH SUCH SWING LOAN IS MADE (I) THE AGGREGATE AMOUNT
        OF ALL OUTSTANDING SWING LOANS SHALL NOT EXCEED $5,000,000 AND (II) THE
        AGGREGATE OUTSTANDING CREDIT EXPOSURE SHALL NOT EXCEED THE AGGREGATE
        COMMITMENT. SWING LOANS SHALL BE IN A MINIMUM AMOUNT OF $100,000.
        INTEREST ON EACH SWING LOAN SHALL BE AT THE FLOATING RATE, SHALL BE
        SECURED AS PART OF THE SECURED OBLIGATIONS BY THE COLLATERAL AND SHALL
        OTHERWISE BE SUBJECT TO ALL THE TERMS AND CONDITIONS APPLICABLE TO
        LOANS, EXCEPT THAT ALL INTEREST THEREON SHALL BE PAYABLE TO THE AGENT
        SOLELY FOR ITS OWN ACCOUNT.

                2.20.2. SWING LOAN BORROWING REQUESTS. THE AGENT MAY MAKE SWING
        LOANS, PROVIDED THAT THE AGENT HAS RECEIVED A REQUEST IN WRITING OR VIA
        TELEPHONE FROM AN AUTHORIZED OFFICER FOR FUNDING OF A SWING LOAN NO
        LATER THAN NOON, DETROIT TIME, ON THE BUSINESS DAY ON WHICH SUCH SWING
        LOAN IS REQUESTED TO BE MADE. THE BORROWER AGREES TO DELIVER PROMPTLY TO
        THE AGENT A WRITTEN CONFIRMATION OF EACH TELEPHONIC NOTICE FOR SWING



<PAGE>   24


        LOANS SIGNED BY AN AUTHORIZED OFFICER. IF THE WRITTEN CONFIRMATION
        DIFFERS IN ANY MATERIAL RESPECT FROM THE ACTION TAKEN BY THE AGENT, THE
        RECORDS OF THE AGENT SHALL GOVERN, ABSENT MANIFEST ERROR.

                2.20.3. REPAYMENT OF SWING LOANS; PARTICIPATION BY LENDERS. (I)
        THE AGENT MAY AT ANY TIME IN ITS SOLE AND ABSOLUTE DISCRETION REQUIRE
        THAT ANY SWING LOAN BE REFUNDED BY A REVOLVING CREDIT LOAN WHICH IS A
        FLOATING RATE BORROWING FROM THE LENDERS, AND UPON WRITTEN NOTICE
        THEREOF BY THE AGENT TO THE LENDERS AND THE BORROWER, THE BORROWER SHALL
        BE DEEMED TO HAVE REQUESTED A REVOLVING CREDIT LOAN WHICH IS A FLOATING
        RATE ADVANCE IN AN AMOUNT EQUAL TO THE AMOUNT OF SUCH SWING LOAN, AND
        SUCH FLOATING RATE ADVANCE SHALL BE MADE TO REFUND SUCH SWING LOAN. EACH
        LENDER SHALL BE ABSOLUTELY, IRREVOCABLY AND UNCONDITIONALLY OBLIGATED TO
        FUND ITS PRO RATA SHARE OF SUCH FLOATING RATE ADVANCE OR, IF APPLICABLE,
        PURCHASE A PARTICIPATING INTEREST IN THE SWING LOANS PURSUANT TO SECTION
        2.20.3(II), AND SUCH OBLIGATION SHALL NOT BE AFFECTED BY ANY
        CIRCUMSTANCE, INCLUDING, WITHOUT LIMITATION, (A) ANY SET-OFF,
        COUNTERCLAIM, RECOUPMENT, DEFENSE OR OTHER RIGHT WHICH SUCH LENDER HAS
        OR MAY HAVE AGAINST THE AGENT OR THE BORROWER OR ANY IF ITS SUBSIDIARIES
        OR ANYONE ELSE FOR ANY REASON WHATSOEVER; (B) THE OCCURRENCE OR
        CONTINUANCE OF AN UNMATURED DEFAULT OR A DEFAULT, SUBJECT TO SECTION
        2.20.3(II); (C) ANY ADVERSE CHANGE IN THE CONDITION (FINANCIAL OR
        OTHERWISE) OF THE BORROWER OR ANY OF ITS SUBSIDIARIES OR ANY OTHER
        GUARANTOR; (D) ANY BREACH OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
        BY ANY OTHER LENDER, THE BORROWER OR ANY GUARANTOR; OR (E) ANY OTHER
        CIRCUMSTANCE, HAPPENING OR EVENT WHATSOEVER, WHETHER OR NOT SIMILAR TO
        ANY OF THE FOREGOING (INCLUDING WITHOUT LIMITATION THE BORROWER'S
        FAILURE TO SATISFY ANY CONDITIONS CONTAINED IN ARTICLE IV OR ANY OTHER
        PROVISION OF THIS AGREEMENT).

                    (ii)  If, due to any Default (including without limitation
        as a RESULT OF THE OCCURRENCE OF AN EVENT OF DEFAULT WITH RESPECT TO THE
        BORROWER OR ANY OF ITS SUBSIDIARIES PURSUANT TO SECTIONS 7.6 OR 7.7)
        FLOATING RATE LOANS MAY NOT BE MADE BY THE LENDERS AS DESCRIBED IN
        SECTION 2.1(E)(II), THEN (A) THE BORROWER AGREES THAT EACH SWING LOAN
        NOT PAID PURSUANT TO SECTION 2.20.3(I) SHALL BEAR INTEREST, PAYABLE ON
        DEMAND BY THE AGENT, AT THE FLOATING RATE PLUS 2%, AND (B) EFFECTIVE ON
        THE DATE EACH SUCH FLOATING RATE LOAN WOULD OTHERWISE HAVE BEEN MADE,
        EACH LENDER SEVERALLY AGREES THAT IT SHALL ABSOLUTELY, AUTOMATICALLY,
        IRREVOCABLY AND UNCONDITIONALLY, WITHOUT REGARD TO THE OCCURRENCE OF ANY
        UNMATURED DEFAULT OR DEFAULT OR ANY OTHER CIRCUMSTANCES AS DESCRIBED IN
        SECTION 2.20.3(I)(A) (E) ABOVE AND WITHOUT FURTHER ACTION BY ANY PARTY
        HERETO, IN LIEU OF DEEMED DISBURSEMENT OF REVOLVING CREDIT LOANS, TO THE
        EXTENT OF SUCH LENDER'S PRO RATA SHARE, PURCHASE A PARTICIPATING
        INTEREST IN THE SWING LOANS BY PAYING ITS PRO RATA SHARE THEREOF. EACH
        LENDER WILL IMMEDIATELY TRANSFER TO THE AGENT, IN IMMEDIATELY AVAILABLE
        FUNDS, THE AMOUNT OF ITS PARTICIPATION. AFTER SUCH PAYMENT TO THE AGENT,
        EACH LENDER SHALL SHARE ON A PRO RATA BASIS (CALCULATED BY REFERENCE TO
        ITS PRO RATA SHARE) IN ANY INTEREST WHICH ACCRUES THEREON AND IN ALL
        REPAYMENTS THEREOF. IF AND TO THE EXTENT THAT ANY LENDER SHALL NOT HAVE
        SO MADE THE AMOUNT OF SUCH PARTICIPATING INTEREST AVAILABLE TO THE
        AGENT, SUCH LENDER AND THE BORROWER SEVERALLY AGREE TO PAY TO THE AGENT
        FORTHWITH ON DEMAND SUCH AMOUNT TOGETHER WITH INTEREST THEREON, FOR EACH
        DAY FROM THE DATE OF DEMAND (OR, IF SUCH DEMAND IS MADE AFTER 11:00 A.M.
        (DETROIT TIME) ON SUCH DATE, FROM THE NEXT SUCCEEDING BUSINESS DAY) BY
        THE AGENT UNTIL THE DATE SUCH AMOUNT IS PAID TO THE AGENT, AT (X) IN THE
        CASE OF THE BORROWER, THE INTEREST RATE SPECIFIED ABOVE AND (Y) IN THE
        CASE OF SUCH LENDER, THE FEDERAL FUNDS EFFECTIVE RATE FOR THE FIRST
        THREE DAYS AFTER THE DATE OF DEMAND BY THE AGENT AND THEREAFTER AT THE
        INTEREST RATE SPECIFIED ABOVE.

        2.21.  Replacement of Lender. If the Borrower is required pursuant to
Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender when it is
not required to make such payments to all Lenders, or if any Lender's obligation
to make or continue, or to convert Floating Rate Advances into, Eurodollar
Advances shall be suspended pursuant to Section 3.3 when not all Lenders'
obligations have been suspended or if any Lender is a Defaulting Lender (any
Lender so affected an "Affected Lender"), the Borrower may elect, if such
amounts continue to be charged or such suspension is still effective, to replace
such Affected Lender as a Lender party to this Agreement, provided that no
Default or Unmatured Default shall have occurred and be continuing at the time
of such replacement, and provided further that, concurrently with such
replacement, (i) another bank or other entity which is reasonably satisfactory
to the Borrower and the Agent shall agree, as of such date, to purchase for cash
the Advances and other Obligations due to the Affected Lender pursuant to an
assignment substantially in the form of Exhibit C and to become a Lender for all
purposes under this Agreement and to assume all obligations of the Affected
Lender to be terminated as of such date and to comply with the requirements of
Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such
Affected Lender in same day funds on the day of such replacement all interest,
fees and other amounts then accrued but unpaid to such Affected
<PAGE>   25


Lender by the Borrower hereunder to and including the date of termination,
including without limitation payments due to such Affected Lender under Sections
3.1, 3.2 and 3.5.



                                  ARTICLE III

                            YIELD PROTECTION; TAXES


        3.1.   Yield Protection. If, on or after the date of this Agreement, the
adoption of any law or any governmental or quasi-governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law), or any
change in the interpretation or administration thereof by any governmental or
quasi-governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or
applicable Lending Installation or the LC Issuer with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency:

        (i)    subjects any Lender or any applicable Lending Installation or the
               LC Issuer to any Taxes, or changes the basis of taxation of
               payments (other than with respect to Excluded Taxes) to any
               Lender in respect of its Eurodollar Loans Facility LCs or
               participations therein, or

        (ii)   imposes or increases or deems applicable any reserve, assessment,
               insurance charge, special deposit or similar requirement against
               assets of, deposits with or for the account of, or credit
               extended by, any Lender or any applicable Lending Installation or
               the LC Issuer (other than reserves and assessments taken into
               account in determining the interest rate applicable to Eurodollar
               Advances), or

        (iii)  imposes any other condition the result of which is to
               increase the cost to any Lender or any applicable Lending
               Installation or the LC Issuer of making, funding or maintaining
               its Eurodollar Loans, or of issuing or participating in Facility
               LCs, or reduces any amount receivable by any Lender or any
               applicable Lending Installation or the LC Issuer in connection
               with its Eurodollar Loans, Facility LC or participations therein,
               or requires any Lender or any applicable Lending Installation or
               LC Issuer to make any payment calculated by reference to the
               amount of Eurodollar Loans, Facility LCs or participations
               therein held or interest or LC Fees received by it, by an amount
               deemed material by such Lender or the LC Issuer as the case may
               be,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation or the LC Issuer, as the case may be, of making
or maintaining its Eurodollar Loans or Commitment or of issuing or participating
in Facility LCs or to reduce the return received by such Lender or applicable
Lending Installation or the LC Issuer, as the case may be, in connection with
such Eurodollar Loans, Facility LCs or participations therein, then, within 30
days of demand by such Lender or the LC Issuer, as the case may be, the Borrower
shall pay such Lender or the LC Issuer, as the case may be, such additional
amount or amounts as will compensate such Lender or the LC Issuer, as the case
may be, for such increased cost or reduction in amount received.

        3.2.   Changes in Capital Adequacy Regulations. If a Lender, the Agent
or the LC Issuer determines the amount of capital required or expected to be
maintained by such Lender, the Agent or the LC Issuer, any Lending Installation
of such Lender or LC Issuer, or any corporation controlling such Lender, the
Agent or the LC Issuer is increased as a result of a Change, then, within 30
days of demand by such Lender, the Agent or the LC Issuer, the Borrower shall
pay such Lender, the Agent or the LC Issuer the amount necessary to compensate
for any shortfall in the rate of return on the portion of such




<PAGE>   26


increased capital which such Lender, the Agent or the LC Issuer determines is
attributable to this Agreement, its Outstanding Credit Exposure or its
Commitment to make Loans and issue or participate in Facility LCs, as the case
may be, hereunder (after taking into account such Lender's policies as to
capital adequacy). "Change" means (i) any change after the date of this
Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of or change
in any other law, governmental or quasi-governmental rule, regulation, policy,
guideline, interpretation, or directive (whether or not having the force of law)
after the date of this Agreement which affects the amount of capital required or
expected to be maintained by any Lender, the Agent or the LC Issuer or any
Lending Installation or any corporation controlling any Lender, the Agent or LC
Issuer. "Risk-Based Capital Guidelines" means (i) the risk-based capital
guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle Committee on Banking Regulation and Supervisory
Practices Entitled "International Convergence of Capital Measurements and
Capital Standards," including transition rules, and any amendments to such
regulations adopted prior to the date of this Agreement.

        3.3.   Availability of Types of Advances. If any Lender determines that
maintenance of its Eurodollar Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to Eurodollar Advances does not
accurately reflect the cost of making or maintaining Eurodollar Advances, then
the Agent shall suspend the availability of Eurodollar Advances and require any
affected Eurodollar Advances to be repaid or converted to Floating Rate
Advances, subject to the payment of any funding indemnification amounts required
by Section 3.4.

        3.4.   Funding Indemnification. If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made on the date specified by the Borrower for any reason other
than default by the Lenders, the Borrower will indemnify each Lender for any
loss or cost incurred by it resulting therefrom, including, without limitation,
any loss or cost in liquidating or employing deposits acquired to fund or
maintain such Eurodollar Advance.

        3.5.   Taxes. (i) All payments by the Borrower to or for the account of
any Lender, the LC Issuer or the Agent hereunder or under any Note or Facility
LC Application shall be made free and clear of and without deduction for any and
all Taxes. If the Borrower shall be required by law to deduct any Taxes from or
in respect of any sum payable hereunder to any Lender, the LC Issuer or the
Agent, (a) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 3.5) such Lender, the LC Issuer or the Agent (as the
case may be) receives an amount equal to the sum it would have received had no
such deductions been made, (b) the Borrower shall make such deductions, (c) the
Borrower shall pay the full amount deducted to the relevant authority in
accordance with applicable law and (d) the Borrower shall furnish to the Agent
the original copy of a receipt evidencing payment thereof within 30 days after
such payment is made.

        (ii)   In addition, the Borrower hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or Facility LC Application or from the execution or delivery of, or
otherwise with respect to, this Agreement or any Note or Facility LC Application
("Other Taxes").

        (iii)  The Borrower hereby agrees to indemnify the Agent, the LC Issuer
and each Lender for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed on amounts payable under this
Section 3.5) paid by the Agent , the LC Issuer or such Lender and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto. Payments due under this indemnification shall be made within 30 days of
the date the Agent, the LC Issuer or such Lender makes demand therefor pursuant
to Section 3.6.

        (iv)   Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a "Non-U.S. Lender") agrees that it
will, on or



<PAGE>   27


prior to the date of this Agreement or, in the case of any Transferee, on or
prior to the date of the assignment pursuant to Section 12.3 by which such
Transferee becomes a Lender, (i) deliver to each of the Borrower and the Agent
two duly completed copies of United States Internal Revenue Service Form 1001 or
4224, certifying in either case that such Lender is entitled to receive payments
under this Agreement without deduction or withholding of any United States
federal income taxes, and (ii) deliver to each of the Borrower and the Agent a
duly completed United States Internal Revenue Form W-8 or W-9, as the case may
be, and certify that it is entitled to an exemption from United States backup
withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of
the Borrower and the Agent (x) renewals or additional copies of such form (or
any successor form) on or before the date that such form expires or becomes
obsolete or incorrect, and (y) after the occurrence of any event requiring a
change in the most recent forms so delivered by it, such additional forms or
amendments thereto as may be reasonably requested by the Borrower or the Agent.

        (v)   For any period during which a Non-U.S. Lender has failed to
provide the Borrower with an appropriate form pursuant to clause (iv), above
(unless such failure is due to a change in treaty, law or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, occurring subsequent to the date on which a form originally was
required to be provided), such Non-U.S. Lender shall not be entitled to
indemnification under this Section 3.5 with respect to Taxes imposed by the
United States; provided that, should a Non-U.S. Lender which is otherwise exempt
from or subject to a reduced rate of withholding tax become subject to Taxes
because of its failure to deliver a form required under clause (iv), above, the
Borrower shall take such steps as such Non-U.S. Lender shall reasonably request
to assist such Non-U.S. Lender to recover such Taxes.

        (vi)  Any Lender that is entitled to an exemption from or reduction of
withholding tax with respect to payments under this Agreement or any Note
pursuant to the law of any relevant jurisdiction or any treaty shall deliver to
the Borrower (with a copy to the Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by
applicable law as will permit such payments to be made without withholding or at
a reduced rate.

        (vii) If the U.S. Internal Revenue Service or any other governmental
authority of the United States or any other country or any political subdivision
thereof asserts a claim that the Agent or the Borrower, as the case may be, did
not properly withhold tax from amounts paid to or for the account of any Lender
(because the appropriate form was not delivered or properly completed, because
such Lender failed to notify the Agent or the Borrower, as the case may be, of a
change in circumstances which rendered its exemption from withholding
ineffective, or for any other reason), such Lender shall indemnify the Agent or
the Borrower, as the case may be, fully for all amounts paid, directly or
indirectly, by the Agent or the Borrower, as the case may be, as tax,
withholding therefor, or otherwise, including penalties and interest, and
including taxes imposed by any jurisdiction on amounts payable to the Agent or
the Borrower, as the case may be, under this subsection, together with all costs
and expenses related thereto (including attorneys fees and time charges of
attorneys for the Agent or the Borrower, as the case may be, which attorneys may
be employees of the Agent or the Borrower, as the case may be). The obligations
of the Lenders under this Section 3.5(vii) shall survive the payment of the
Obligations and termination of this Agreement.

        3.6.  Lender Statements; Survival of Indemnity. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Loans to reduce any liability of the Borrower to such
Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in
the judgment of such Lender, disadvantageous to such Lender. Each Lender shall
deliver a written statement of such Lender to the Borrower (with a copy to the
Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such
written statement shall set forth in reasonable detail the calculations upon
which such Lender determined such amount and shall be final, conclusive and
binding on the Borrower in the absence of manifest error. Determination of
amounts payable under such Sections in connection with a Eurodollar Loan shall
be calculated as though each Lender funded its Eurodollar Loan through the
purchase of a deposit of the type and maturity corresponding to the deposit used
as a reference in determining the Eurodollar Rate applicable to such Loan,
whether in fact that is the case or not. Unless otherwise provided herein, the
amount specified in the written statement of any Lender shall be payable on
demand after




<PAGE>   28

receipt by the Borrower of such written statement. The obligations of the
Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the
Obligations and termination of this Agreement.



                                   ARTICLE IV

                              CONDITIONS PRECEDENT

                Borrower, together with all amendments, and a certificate of

                Officers and any other officers of the Borrower authorized to
                sign the Loan Documents to which the Borrower is a party, upon

                authorizations as the Agent may have reasonably requested.

        (vii)   Executed copies of all Guaranties, Collateral Documents and

                                   ARTICLE V

                         REPRESENTATIONS AND WARRANTIES


     In order to induce Lenders, the LC Issuer and the Agent to enter into
this Agreement and to make each Credit Extension, the Borrower represents and
warrants to each Lender, the LC Issuer and the Agent, on the date hereof and on
each Credit Extension Date, that the following statements are true, correct and
complete (it being understood and agreed that the representations and warranties
made on the date hereof are deemed to be made concurrently with, and giving
effect to, the consummation of the Zenith Acquisition and the merger of Zenith
and the Borrower, with Zenith being the surviving entity and assuming all
obligations of and becoming the Borrower as contemplated hereby):

     5.1.   Existence and Standing. Each of the Borrower and its Subsidiaries is
a corporation or limited liability company duly and properly incorporated or
organized, as the case may be, validly existing and (to the extent such concept
applies to such entity) in good standing under the laws of its jurisdiction of
incorporation or organization and has all requisite authority to conduct its
business in each jurisdiction in which its business is conducted except where
the failure to do so could not result in a Material Adverse Effect.

     5.2.   Authorization and Validity. The Borrower has the power and authority
and legal right to execute and deliver the Loan Documents to which it is a party
and to perform its obligations thereunder. The execution and delivery by the
Borrower of the Loan Documents to which it is a party and the performance of its
obligations thereunder have been duly authorized by proper corporate
proceedings, and the Loan Documents to which the Borrower is a party constitute
legal, valid and binding obligations of the Borrower enforceable against the
Borrower in accordance with their terms, except as enforceability may be limited
by bankruptcy, insolvency or similar laws affecting the enforcement of
creditors' rights generally and subject also to the availability of equitable
remedies if equitable remedies are sought.

     5.3.   No Conflict; Government Consent. Neither the execution and delivery
by the Borrower or any of its Subsidiaries of the Loan Documents to which any of
them is a party, nor the consummation of the transactions therein contemplated,
nor compliance with the provisions thereof will violate (i) any Requirement of
Law binding on the Borrower or any of its Subsidiaries or their respective
Property or (ii) the Borrower's or any Subsidiary's articles or certificate of
incorporation, articles or certificate of organization, by-laws, or operating or
other management agreement, as the case may be, or (iii) the provisions of any
indenture, instrument or agreement to which the Borrower or any of its
Subsidiaries is a party or is subject, or by which it, or its Property, is
bound, or conflict with or constitute a default thereunder, or result in, or
require, the creation or imposition of any Lien in, of or on the Property of the
Borrower or a Subsidiary pursuant to the terms of any such indenture, instrument
or agreement. No order, consent, adjudication, approval, license, authorization,
or validation of, or filing, recording or registration with, or exemption by, or
other action in respect of any governmental or public body or authority, or any
subdivision thereof, which has not been obtained by the Borrower or any of its
Subsidiaries, is required to be obtained by the Borrower or any of its
Subsidiaries in connection with the execution and



<PAGE>   31


delivery of the Loan Documents, the Credit Extensions under this Agreement, the
payment and performance by the Borrower of the Obligations or the legality,
validity, binding effect or enforceability of any of the Loan Documents.

     5.4.   FINANCIAL STATEMENTS. THE DECEMBER 31, 1998 AND MARCH 31, 1999
CONSOLIDATED FINANCIAL STATEMENTS OF ZENITH AND ITS SUBSIDIARIES HERETOFORE
DELIVERED TO THE LENDERS WERE PREPARED IN ACCORDANCE WITH AGREEMENT ACCOUNTING
PRINCIPLES IN EFFECT ON THE DATE SUCH STATEMENTS WERE PREPARED AND FAIRLY
PRESENT THE CONSOLIDATED FINANCIAL CONDITION AND OPERATIONS OF ZENITH AND ITS
SUBSIDIARIES AT SUCH DATE AND THE CONSOLIDATED RESULTS OF THEIR OPERATIONS FOR
THE PERIOD THEN ENDED, SUBJECT, IN THE CASE OF INTERIM STATEMENTS, TO ROUTINE
YEAR-END ADJUSTMENTS AND THE ABSENCE OF FOOTNOTES. THE PRO FORMA FINANCIAL
STATEMENTS AND PROJECTIONS FAIRLY PRESENT THE PRO FORMA CONSOLIDATED FINANCIAL
CONDITION OF THE BORROWER AND ITS SUBSIDIARIES AFTER GIVING EFFECT TO THE ZENITH
ACQUISITION IN ACCORDANCE WITH AGREEMENT ACCOUNTING PRINCIPLES, AND CONTAIN
REASONABLE ASSUMPTIONS AND GIVE APPROPRIATE EFFECT TO THOSE ASSUMPTIONS, AND ARE
BASED ON ESTIMATES AND ASSUMPTIONS CONSIDERED REASONABLE BY THE BORROWERS
MANAGEMENT AND THE BEST INFORMATION AVAILABLE TO THE BORROWERS MANAGEMENT AT THE
TIME MADE, AND USE INFORMATION CONSISTENT WITH THE PLANS OF THE BORROWER (IT
BEING RECOGNIZED BY THE LENDERS THAT SUCH PROJECTIONS AS TO FUTURE EVENTS ARE
NOT TO BE VIEWED AS FACTS AND NECESSARILY WERE BASED ON NUMEROUS ASSUMPTIONS
WITH RESPECT TO INDUSTRY PERFORMANCE, GENERAL BUSINESS, ECONOMIC AND COMPETITIVE
CONDITIONS AND UNCERTAINTIES, TAXES AND OTHER MATTERS WHICH ARE BEYOND THE
CONTROL OF THE BORROWER, SUCH THAT THERE CAN BE NO ASSURANCE THAT SUCH
PROJECTIONS WILL BE REALIZED AND ACTUAL RESULTS MAY DIFFER FROM THE PROJECTED
RESULTS).

     5.5.   Material Adverse Change. Since December 31, 1998 there has been no
change in the business, Property, prospects, condition (financial or otherwise)
or results of operations of the Borrower and its Subsidiaries or if Trianon and
its Subsidiaries which could reasonably be expected to have a Material Adverse
Effect.

     5.6.   Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes due pursuant to said returns or pursuant to any
assessment received by the Borrower or any of its Subsidiaries, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided in accordance with Agreement Accounting Principles
and as to which no Lien exists. The United States income tax returns of the
Borrower and its Subsidiaries have been audited by the Internal Revenue Service
through the fiscal year ended December 31, 1994. No tax liens have been filed
and no claims are being asserted with respect to any such taxes. The charges,
accruals and reserves on the books of the Borrower and its Subsidiaries in
respect of any taxes or other governmental charges are adequate.

     5.7.   Litigation and Contingent Obligations. Except as set forth on
Schedule 5.7, there is no litigation, arbitration, governmental investigation,
proceeding or inquiry pending or, to the knowledge of any of their officers,
threatened against or affecting the Borrower or any of its Subsidiaries which
could reasonably be expected to have a Material Adverse Effect or which seeks to
prevent, enjoin or delay the making of any Credit Extension or the Zenith
Acquisition. Other than any liability incident to any litigation, arbitration or
proceeding which could not reasonably be expected to have a Material Adverse
Effect, the Borrower has no material contingent obligations not provided for or
disclosed in the financial statements referred to in Section 5.4.

     5.8.   Subsidiaries. Schedule 5.8 contains an accurate list of all
Subsidiaries of the Borrower as of the date of this Agreement, setting forth
their respective jurisdictions of organization and the percentage of their
respective capital stock or other ownership interests owned by the Borrower or
other Subsidiaries. All of the issued and outstanding shares of capital stock or
other ownership interests of such Subsidiaries have been (to the extent such
concepts are relevant with respect to such ownership interests) duly authorized
and issued and are fully paid and non-assessable.

     5.9.   ERISA. The Unfunded Liabilities of all Single Employer Plans do not
in the aggregate exceed $100,000. Neither the Borrower nor any other member of
the Controlled Group contributes to or is a sponsor of a Multiemployer Plans.
Each Plan complies in all material respects with all applicable requirements of
law and regulations. No Reportable Event has occurred with respect to any Plan
which could have a Material Adverse Effect. Neither the Borrower nor any other
member of the Controlled Group has withdrawn from any Plan or initiated steps to
do so, and no steps have been taken to reorganize or terminate any Plan, which
could have a Material Adverse Effect.

     5.10.  Accuracy of Information. To the Borrower's knowledge, no
information, exhibit or report furnished by or on behalf of the Borrower or any
of its Subsidiaries to the Agent or to any Lender in connection with the
negotiation of, or compliance with, the Loan Documents contained any material
misstatement of fact or omitted to state a material fact or any fact (known to
the Borrower in the case of any document not furnished by the Borrower)
necessary to make the statements contained therein not misleading.



<PAGE>   32



       5.11.  Regulation U. Margin Stock constitutes less than 25% of the value
of those assets of the Borrower and its Subsidiaries which are subject to any
limitation on sale, pledge, or other restriction hereunder or under any
agreement or instrument between the Borrower or any of its Subsidiaries and any
Lender or Affiliate of any Lender relating the Indebtedness within the scope of
Section 7.5.

       5.12.  Material Agreements. Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any charter or other
corporate restriction which could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in (i) any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing Indebtedness.

       5.13.  Compliance With Laws. The Borrower and its Subsidiaries have
complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property or other Requirements
of Law except for any failure to comply with any of the foregoing which could
not reasonably be expected to have a Material Adverse Effect.

       5.14.  Ownership of Properties; Liens. On the date of this Agreement, the
Borrower and its Subsidiaries will have good title, free of all Liens other than
those permitted by Section 6.15, to all of the Property and assets reflected in
the Borrower's most recent consolidated financial statements provided to the
Agent as owned by the Borrower and its Subsidiaries. The Collateral Documents
grant to the Agent, securing the Secured Obligations, a first priority,
enforceable and perfected lien and security interest in all Collateral, subject
only to such Liens permitted by Section 6.15 and such Liens and priorities
permitted by and described in the relevant Collateral Documents for the pledge
of the Capital Stock of SOFEDIT, Aetna Industries, Inc., Aetna Holdings, Inc.
and the Borrower.

       5.15.  Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. 2510.3-101
of an employee benefit plan (as defined in Section 3(3) of ERISA) which is
subject to Title I of ERISA or any plan (within the meaning of Section 4975 of
the Code), and neither the execution of this Agreement nor the making of Credit
Extensions hereunder gives rise to a prohibited transaction within the meaning
of Section 406 of ERISA or Section 4975 of the Code.

       5.16.  Environmental Matters. In the ordinary course of its business, the
Borrower considers the effect of Environmental Laws on the business of the
Borrower and its Subsidiaries, in the course of which they identify and evaluate
potential risks and liabilities accruing to the Borrower due to Environmental
Laws. On the basis of this consideration, except as set forth in Schedule 5.16,
the Borrower has concluded that Environmental Laws cannot reasonably be expected
to have a Material Adverse Effect. Except as set forth in Schedule 5.16, neither
the Borrower nor any Subsidiary has received any notice to the effect that its
operations are not in material compliance with any of the requirements of
applicable Environmental Laws or are the subject of any federal or state
investigation evaluating whether any remedial action is needed to respond to a
release of any toxic or hazardous waste or substance into the environment, which
non-compliance or remedial action could reasonably be expected to have a
Material Adverse Effect.

       5.17.  Investment Company Act. 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.

       5.18.  Public Utility Holding Company Act. Neither the Borrower nor any
Subsidiary is 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.




<PAGE>   33

       5.19.  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 on the Year 2000 Program the Borrower does not reasonably
anticipate that Year 2000 Issues will have a Material Adverse Effect.

       5.20.  SUBORDINATED INDEBTEDNESS. ALL REPRESENTATIONS AND WARRANTIES OF
THE BORROWER AND OF TRIANON CONTAINED IN ANY SUBORDINATED DEBT DOCUMENT ARE TRUE
AND CORRECT IN ALL MATERIAL RESPECTS. ALL SUBORDINATED DEBT DOCUMENTS ARE
DESCRIBED ON SCHEDULE 5.20 HERETO. ALL SECURED OBLIGATIONS AND CONTINGENT
OBLIGATIONS OF TRIANON WITH RESPECT TO THE SECURED OBLIGATIONS ARE SENIOR DEBT
AND ARE ENTITLED TO THE BENEFITS OF THE SUBORDINATION PROVISIONS OF THE
SUBORDINATED DEBT DOCUMENTS. THERE IS NO EVENT OF DEFAULT OR EVENT OR CONDITION
WHICH COULD BECOME AN EVENT OF DEFAULT WITH NOTICE OR LAPSE OF TIME OR BOTH,
UNDER THE SUBORDINATED DEBT DOCUMENTS AND EACH OF THE SUBORDINATED DEBT
DOCUMENTS IS IN FULL FORCE AND EFFECT. THE LENDERS UNDER THE SUBORDINATED DEBT
DOCUMENTS HAVE A COMMITMENT SATISFACTORY TO THE AGENT TO LEND UP TO $75,000,000
TO TRIANON AND TRIANON HAS A COMMITMENT SATISFACTORY TO THE AGENT TO LEND UP TO
$75,000,000 TO THE BORROWER UNDER THE SUBORDINATED DEBT DOCUMENTS, WHICH
COMMITMENTS ARE IN FULL FORCE AND EFFECT.

Financial Officer of the Borrower, that attests to the existence and adequacy
of, and summarizes, the property and casualty insurance program carried by the
Borrower with respect to itself and its Subsidiaries and that has been furnished
by the Borrower to the Agent and the Lenders, is complete and accurate. This
summary includes the insurer's or insurers' name(s), policy number(s),
expiration date(s), amount(s) of coverage, type(s) of coverage, exclusion(s),
and deductibles. This summary also includes similar information, and describes
any reserves, relating to any self-insurance program that is in effect.

       5.22.  Solvency. (i) Immediately after the consummation of the
transactions to occur on the date hereof and immediately following the making of
the Credit Extensions on the date hereof and after giving effect to the
application of the proceeds of such Credit Extensions, (a) the fair value of the
assets of the Borrower and its Subsidiaries on a consolidated basis, at a fair
valuation, will exceed the debts and liabilities, subordinated, contingent or
otherwise, of the Borrower and its Subsidiaries on a consolidated basis; (b) the
present fair saleable value of the Property of the Borrower and its Subsidiaries
on a consolidated basis will be greater than the amount that will be required to
pay the probable liability of the Borrower and its Subsidiaries on a
consolidated basis on their debts and other liabilities, subordinated,
contingent or otherwise, as such debts and other liabilities become absolute and
matured; (c) the Borrower and its Subsidiaries on a consolidated basis will be
able to pay their debts and liabilities, subordinated, contingent or otherwise,

Subsidiaries to, and does not believe that it or any of its Subsidiaries will,
incur debts beyond its ability to pay such debts as they mature, taking into
account the timing of and amounts of cash to be received by it or any such
Subsidiary and the timing of the amounts of cash to be payable on or in respect
of its Indebtedness or the Indebtedness of any such Subsidiary.

       5.23.  ZENITH ACQUISITION. SIMULTANEOUSLY WITH THE DISBURSEMENT OF THE

ACQUISITION IN ACCORDANCE WITH THE ZENITH ACQUISITION DOCUMENTS AND IN

                                  ARTICLE VIII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES


       8.1.  Acceleration; Facility LC Collateral Account. (i) If any Default
described in Section 7.6 or 7.7 occurs and is continuing with respect to the
Borrower, the obligations of the Lenders to make Revolving Credit Loans
hereunder, the obligation and power of the LC Issuer to issue Facility LCs and
the power of the Agent to make Swing Loans shall automatically terminate and the
Obligations shall immediately become due and payable without any election or
action on the part of the Agent, the LC Issuer or any Lender and the Borrower
will be and become thereby unconditionally obligated, without any further
notice, act or demand, to pay to the Agent an amount in immediately available
funds, which funds shall be held in the Facility LC Collateral Account, equal to
the difference of (x) the amount of LC Obligations at such time, less (v) the
amount on deposit in the Facility LC Collateral Accountant such time which is
free and clear of all rights and claims of third parties and has not been
applied against the Obligations (such difference, the "Collateral Shortfall
Amount"). If any other Default occurs and is continuing, the Required Lenders
(or the Agent with the consent of the Required Lenders) may (a) terminate or
suspend the obligations of the Lenders to make Revolving Credit Loans hereunder,
the obligation and power of the LC Issuer to issue Facility LCs, and the power
of the Agent to make Swing Loans, or declare the Obligations to be due and
payable, or both, whereupon the Obligations shall become immediately due and
payable, without presentment, demand, protest or notice of any kind, all of
which the Borrower hereby expressly waives and (b) upon notice to the Borrower
and in addition to the continuing right to demand payment of all amounts payable
under this Agreement, make demand on the Borrower to pay, and the Borrower will,
forthwith upon such demand and without any further notice or act, pay to the
Agent the Collateral Shortfall Amount, which funds shall be deposited in the
Facility LC Collateral Account.

       (ii)  If at any time while any Default is continuing, the Agent
determines that the Collateral Shortfall Amount at such time is greater than
zero, the Agent may make demand on the Borrower to pay, and the Borrower will,
forthwith upon such demand and without any further notice or act, pay to the
Agent the Collateral Shortfall Amount, which funds shall be deposited in the
Facility LC Collateral Account.

       (iii) The Agent may at any time or from time to time after funds are
deposited in the Facility LC Collateral Account, apply such funds to the payment
of the Obligations and any other amounts as shall from time to time have become
due and payable by the Borrower to the Lenders or the LC Issuer under the Loan
Documents.

       (iv)  At any time while any Default is continuing, neither the Borrower
nor any Person claiming on behalf of or through the Borrower shall have any
right to withdraw any of the funds held in the Facility LC Collateral Account.
After all of the Obligations have been indefeasibly paid in full and the
Aggregate Commitment has been terminated, any funds remaining in the Facility LC
Collateral Account shall be returned by the Agent to the Borrower or paid to
whomever may be legally entitled thereto at such time.

       (v)   If, within 30 days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans and
the obligation and power of the LC Issuer to issue Facility LCs hereunder and
the power of the Agent to make Swing Loans as a result of any Default (other
than any Default as described in Section 7.6 or 7.7 with respect to the
Borrower) and before any judgment or decree for the payment of the Obligations
due shall have been



<PAGE>   44


obtained or entered, the Required Lenders (in their sole discretion) shall so
direct, the Agent shall, by notice to the Borrower, rescind and annul such
acceleration and/or termination.

       8.2.  Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of all of the Lenders:

      (i)    Extend the final maturity of any Loan, or extend the expiry date of
             any Facility LC to a date after the Facility Termination Date or
             forgive all or any portion of the principal amount thereof or any
             Reimbursement Obligation related thereto, or reduce the rate or
             extend the time of payment of interest or fees thereon or
             Reimbursement Obligations related thereto.

      (ii)   Reduce the percentage specified in the definition of Required
             Lenders.

      (iii)  Extend the Facility Termination Date, or reduce the amount or
             extend the payment date for, the mandatory payments required under
             Section 2.2, or permit the Borrower to assign its rights under this
             Agreement.

      (iv)   Amend this Section 8.2.

      (v)    Except as allowed in the Loan Documents, release any material
             Guarantor or release all or substantially all of the Collateral.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent, and no amendment of any
provision relating to the LC Issuer shall be effective without the written
consent of the LC Issuer. No increase in the Commitment of any Lender shall be
permitted without the consent of such Lender. The Agent may waive payment of the
fee required under Section 12.3.2 without obtaining the consent of any other
party to this Agreement. Notwithstanding anything herein to the contrary, no
Defaulting Lender shall be entitled to vote (whether to consent or to withhold
its consent) with respect to any amendment, modification, termination or waiver
and, for purposes of the determining the Required Lenders, the Commitments and
the Outstanding Credit Exposure of each Defaulting Lender shall be disregarded
and the Agent shall have the ability, but not the obligation, to replace any
Defaulting Lender with another lender or lenders.

       8.3.  Preservation of Rights. No delay or omission of the Lenders, the LC
Issuer or the Agent to exercise any right under the Loan Documents shall impair
such right or be construed to be a waiver of any Default or an acquiescence
therein, and the making of a Credit Extension notwithstanding the existence of a
Default or the inability of the Borrower to satisfy the conditions precedent to
such Credit Extension shall not constitute any waiver or acquiescence. Any
single or partial exercise of any such right shall not preclude other or further
exercise thereof or the exercise of any other right, and no waiver, amendment or
other variation of the terms, conditions or provisions of the Loan Documents
whatsoever shall be valid unless in writing signed by the Lenders required
pursuant to Section 8.2, and then only to the extent in such writing
specifically set forth. All remedies contained in the Loan Documents or by law
afforded shall be cumulative and all shall be available to the Agent, the LC
Issuer and the Lenders until the Obligations have been paid in full. The Agent
may, and upon being directed to do so by the Required Lenders, shall, in
addition to all other remedies under the Loan Documents, exercise and enforce
any and all other rights and remedies arising under any Loan Document, under
applicable law or otherwise, in any manner deemed appropriate by the Agent,
including suit and equity, action at law or other appropriate proceedings,
whether for the specific performance (to the extent permitted by law) of any
covenant or agreement contained in any Loan Document or in the aid of the
exercise of any power granted in any Loan Document.

       8.4   Distribution of Proceeds of Collateral. All proceeds of any
realization on the Collateral pursuant to the Collateral Documents to be applied
to the Secured Obligations (subject to any priorities and other provisions in
the Collateral Documents, and it is acknowledged that the indebtedness,
obligations and liabilities secured by the Capital Stock of SOFEDIT and existing
prior to the date hereof shall be entitled to the proceeds of such Collateral
before the application thereof to the Secured Obligations) and any payments
received by the Agent or any Lender pursuant to the Guaranties subsequent to and
during the continuance of any Default, shall be allocated and distributed by the
Agent as follows:

             (a)   First, to the payment of all reasonable costs and expenses,
including without limitation all reasonable attorneys' fees, of the Agent in
connection with the enforcement of the Loan Documents and otherwise
administering this Agreement;

             (b)   Second, to the payment of all fees required to be paid under
any Loan Document including commitment fees, owing to the Lenders, the LC Issuer
and Agent pursuant to the Lender Indebtedness on a pro rata basis in accordance
with the Obligations consisting of fees owing to the Lenders and Agent under the
Obligations, for application to payment of such liabilities;

             (c)   Third, to the Lenders (and/or their Affiliates in connection
with any Rate Hedging Obligations which are part of the Secured Obligations),
the LC Issuer and the Agent on a pro rata basis in accordance with the Secured
Obligations consisting of principal (including without limitation any cash
collateral for any outstanding Facility Letters of Credit), interest and Rate
Hedging Obligations which are part of the Secured Obligations, for application
to payment of such Secured Obligations;

             (d)   Fourth, to the payment of any and all other Secured
Obligations owing to the Lenders, the LC Issuer and the Agent on a pro rata
basis in accordance with the total amount of such Obligations owing to each of
the Lenders and the Agent, for application to payment of such Secured
Obligations; and

             (e)   Fifth, to the Borrower, its Subsidiaries or such other Person
as may be legally entitled thereto.

Notwithstanding the foregoing, no payments of principal, interest, fees or other
amounts delivered to the Agent for the account of any Defaulting Lender shall be
delivered by the Agent to such Defaulting Lender. Instead, such payments shall,
for so long as such Defaulting Lender shall be a Defaulting Lender, be held by
the Agent, and the Agent is hereby authorized and directed by all parties hereto
to hold such funds in escrow and apply such funds as follows:

      (i)    First, if applicable to any payments due from such Defaulting
             Lender to the Agent or the LC Issuer, and

      (ii)   Second, to Credit Extensions required to be made by such Defaulting
             Lender on any Borrowing Date to the extent such Defaulting Lender
             fails to make such Credit Extensions.

Notwithstanding the foregoing, upon the termination of all Commitments and the
payment and performance of all of the Secured Obligations (other than those
owing to a Defaulting Lender), any funds then held in escrow by the Agent
pursuant to the preceding sentence shall be distributed to each Defaulting
Lender, pro rata in proportion to amounts that would be due to each Defaulting
Lender but for the fact that it is a Defaulting Lender.




                                   ARTICLE IX

                               GENERAL PROVISIONS



<PAGE>   46


        9.1.  Survival of Representations. All representations and warranties of
the Borrower contained in this Agreement shall survive the making of the Credit
Extensions herein contemplated, but shall only be deemed made on the date hereof
and on each Credit Extension Date.

        9.2.  Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, neither the LC Issuer, the Agent nor any Lender
shall be obligated to extend credit to the Borrower in violation of any
limitation or prohibition provided by any applicable statute or regulation.

        9.3.  Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any
of the provisions of the Loan Documents.

        9.4.  Entire Agreement. The Loan Documents embody the entire agreement
and understanding among the Borrower, the Agent, the LC Issuer and the Lenders
and supersede all prior agreements and understandings among the Borrower, the
Agent, the LC Issuer and the Lenders relating to the subject matter thereof
other than the letters described in Section 10.13.

        9.5.  Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Agent is authorized to act as such). The failure of any Lender to perform any of
its obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns, provided, however, that the parties
hereto expressly agree that the Arranger shall enjoy the benefits of the
provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth
therein and shall have the right to enforce such provisions on its own behalf
and in its own name to the same extent as if it were a party to this Agreement.

        9.6.  Expenses; Indemnification. (i) The Borrower shall reimburse the
Agent and the Arranger for any costs, internal charges and out-of-pocket
expenses (including attorneys' fees and time charges of attorneys for the Agent,
which attorneys may be employees of the Agent) paid or incurred by the Agent or
the Arranger in connection with the preparation, negotiation, execution,
delivery, syndication, review, amendment, modification, and administration of
the Loan Documents. The Borrower also agrees to reimburse the Agent, the
Arranger, the LC Issuer and the Lenders for any costs, internal charges and
out-of-pocket expenses (including attorneys' fees and time charges of attorneys
for the Agent, the Arranger, the LC Issuer and the Lenders, which attorneys may
be employees of the Agent, the Arranger, the LC Issuer or the Lenders) paid or
incurred by the Agent, the Arranger or any Lender in connection with the
collection and enforcement of the Loan Documents. Expenses being reimbursed by
the Borrower under this Section include, without limitation, the cost and
expense of obtaining an appraisal of each parcel of real property or interest in
real property described in the relevant Collateral Documents, which appraisal
shall be in conformity with the applicable requirements of any law or any
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law), or any interpretation thereof, including, without
limitation, the provisions of Title XI of the Financial Institutions Reform,
Recovery and Enforcement Act of 1989, as amended, reformed or otherwise modified
from time to time, and any rules promulgated to implement such provisions and
costs and expenses incurred in connection with the Reports described in the
following sentence. The Borrower acknowledges that from time to time Bank One
may prepare and may distribute to the Lenders (but shall have no obligation or
duty to prepare or to distribute to the Lenders) certain audit reports (the
"Reports") pertaining to the Borrower's assets for internal use by Bank One from
information furnished to it by or on behalf of the Borrower, after Bank One has
exercised its rights of inspection pursuant to this Agreement.

        (ii)  The Borrower hereby further agrees to indemnify the Agent, the
Arranger, the LC Issuer and each Lender, its 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 Agent, the Arranger, the





<PAGE>   47


LC Issuer or any Lender is a party thereto) which any of them may pay or incur
at any time (including without limitation those arising in connection with
transactions which occur prior to the date of this Agreement) arising out of or
relating to this Agreement, the other Loan Documents, the transactions
contemplated hereby (including without limitation the Zenith Acquisition) or the
direct or indirect application or proposed application of the proceeds of any
Credit Extension hereunder except to the extent that they are determined in a
final non-appealable judgment by a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of the party seeking
indemnification. The obligations of the Borrower under this Section 9.6 shall
survive the termination of this Agreement.

        9.7.  Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Agent with sufficient
counterparts so that the Agent may furnish one to each of the Lenders.

        9.8.  Accounting. (i) Except as otherwise expressly provided herein, all
accounting terms used herein shall be interpreted, and all financial statements
and certificates and reports as to financial matters required to be delivered to
the Lenders hereunder shall (unless otherwise disclosed to the Lenders in
writing at the time of delivery thereof in the manner described in subsection
(ii) below) be prepared, in accordance with Agreement Accounting Principles
(subject, in the case of financial statements which are not fiscal year end
statements, to the absence of footnotes and year-end audit adjustments) ;
provided that, if the Borrower notifies the Agent that it wishes to amend any
covenant in Article VI to eliminate the effect of any change in Agreement
Accounting Principles (or if the Agent notifies the Borrower that the Agent or
the Required Lenders wish to amend Article VI for such purpose), then the
Borrower's compliance with such covenants shall be determined on the basis of
Agreement Accounting Principles in effect immediately before the relevant change
in Agreement Accounting Principles became effective until either such notice is
withdrawn or such covenant or any such defined term is amended in a manner
satisfactory to the Borrower and the Required Lenders. Notwithstanding anything
herein, in any financial statements of the Borrower or in Agreement Accounting
Principles to the contrary, for purposes of calculating and determining
compliance with the financial covenants in Section 6.22 and determining the
Applicable Margin and Applicable Fee Rate, including defined terms used therein,
any Acquisitions made by the Borrower or any of its Subsidiaries, including
through mergers or consolidations and including any related financing
transactions, during the period for which such financial covenants and the
Applicable Margin and Applicable Fee Rate were calculated shall be deemed to
have occurred on the first day of the relevant period for which such financial
covenants and the Applicable Margin and Applicable Fee Rate were calculated on a
pro forma basis acceptable to the Agent. Notwithstanding anything in Section
6.22 or in the Pricing Schedule (or the defined terms as used therein), such
financial covenants shall be tested, and the Applicable Margin or Applicable Fee
Rate shall be adjusted, for the first time based on the results for the fiscal
quarter ending September 30, 1999.

              (ii)    The Borrower shall deliver to the Lenders at the same time
as the delivery of any annual financial statement under Section 5.1(i) and (ii)
(x)a description in reasonable detail of any material variation between the
application or other modification of accounting principles employed in the
preparation of such statement and the application or other modification of
accounting principles employed in the preparation of the immediately prior
annual or monthly financial statements as to which no objection has been made in
accordance with the last sentence of subsection (i) above and (y) reasonable
estimates of the difference between such statements arising as a consequence
thereof.

              (iii)   To enable the ready and consistent determination of
compliance with the covenants set forth in Article VI hereof, the Borrower will
not change the last day of its fiscal year from December 31 of each year, or the
last days of the first three fiscal quarters in each of its fiscal years from
March 31, June 30 and September 30 of each year, respectively.

        9.9.  Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.



<PAGE>   48


        9.10.  Nonliability of Lenders. The relationship between the Borrower on
the one hand and the Lenders, the LC Issuer and the Agent on the other hand
shall be solely that of borrower and lender. Neither the Agent, the Arranger,
the LC Issuer nor any Lender shall have any fiduciary responsibilities to the
Borrower. Neither the Agent, the Arranger, the LC Issuer nor any Lender
undertakes any responsibility to the Borrower to review or inform the Borrower
of any matter in connection with any phase of the Borrower's business or
operations. The Borrower agrees that neither the Agent, the Arranger, the LC
Issuer nor any Lender shall have liability to the Borrower (whether sounding in
tort, contract or otherwise) for losses suffered by the Borrower in connection
with, arising out of, or in any way related to, the transactions contemplated
and the relationship established by the Loan Documents, or any act, omission or
event occurring in connection therewith, unless it is determined in a final
non-appealable judgment by a court of competent jurisdiction that such losses
resulted from the gross negligence or willful misconduct of the party from which
recovery is sought. Neither the Agent, the Arranger, the LC Issuer nor any
Lender shall have any liability with respect to, and the Borrower hereby waives,
releases and agrees not to sue for, any special, indirect or consequential
damages suffered by the Borrower in connection with, arising out of, or in any
way related to the Loan Documents or the transactions contemplated thereby.

        9.11.  Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence, except for disclosure (i) to its Affiliates and to other Lenders and
their respective Affiliates, (ii) to legal counsel, accountants, and other

officials to the extent required by such regulatory officials, (iv) to any
Person as requested pursuant to or as required by law, regulation, or legal
process, (v) to any Person in connection with any legal proceeding to which such
Lender is a party, (vi) to such Lender's direct or indirect contractual
counterparties in swap agreements or to legal counsel, accountants and other
professional advisors to such counterparties, and (vii) permitted by Section
12.4.

        9.12.  Nonreliance. Each Lender hereby represents that it is not relying
on or looking to any Margin Stock for the repayment of the Credit Extensions
provided for herein.



                                   ARTICLE X

                                    THE AGENT


        10.1.  Appointment; Nature of Relationship. Bank One, Michigan is hereby
appointed by each of the Lenders as its contractual representative (herein
referred to as the "Agent") hereunder and under each other Loan Document, and
each of the Lenders irrevocably authorizes the Agent to act as the contractual
representative of such Lender with the rights and duties expressly set forth
herein and in the other Loan Documents. The Agent agrees to act as such
contractual representative upon the express conditions contained in this Article
X. Notwithstanding the use of the defined term "Agent," it is expressly
understood and agreed that the Agent shall not have any fiduciary
responsibilities to any Lender by reason of this Agreement or any other Loan
Document and that the Agent is merely acting as the contractual representative
of the Lenders with only those duties as are expressly set forth in this
Agreement and the other Loan Documents. In its capacity as the Lenders'
contractual representative, the Agent (i) does not hereby assume any fiduciary
duties to any of the Lenders, (ii) is a "representative" of the Lenders within
the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting
as an independent contractor, the rights and duties of which are limited to
those expressly set forth in this Agreement and the other Loan Documents. Each
of the Lenders hereby agrees to assert no claim against the Agent on any agency
theory or any other theory of liability for breach of fiduciary duty, all of
which claims each Lender hereby waives.

        10.2.  Powers. The Agent shall have and may exercise such powers under
the Loan Documents as are specifically delegated to the Agent by the terms of
each thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no implied duties to the Lenders, or any obligation to the
Lenders to take any action thereunder except any action specifically provided by
the Loan Documents to be taken by the Agent.




<PAGE>   49


        10.3.  General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
to the extent such action or inaction is determined in a final non-appealable
judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

        10.4.  No Responsibility for Loans, Recitals, etc. 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 (a) any statement, warranty
or representation made in connection with any Loan Document or any borrowing
hereunder; (b) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (c) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; (f) the
value, sufficiency, creation, perfection or priority of any Lien in any
collateral security; or (g) the financial condition of the Borrower or any
guarantor of any of the Obligations or of any of the Borrower's or any such
guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to
the Lenders information that is not required to be furnished by the Borrower to
the Agent at such time, but is voluntarily furnished by the Borrower to the
Agent (either in its capacity as Agent or in its individual capacity).

        10.5.  Action on Instructions of Lenders. The Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder and under
any other Loan Document in accordance with written instructions signed by the
Required Lenders, and such instructions and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders. The Lenders hereby
acknowledge that the Agent shall be under no duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
or any other Loan Document unless it shall be requested in writing to do so by
the Required Lenders. The Agent shall be fully justified in failing or refusing
to take any action hereunder and under any other Loan Document unless it shall
first be indemnified to its satisfaction by the Lenders pro rata against any and
all liability, cost and expense that it may incur by reason of taking or
continuing to take any such action.

        10.6.  Employment of Agents and Counsel. The Agent may execute any of
its duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.

        10.7.  Reliance on Documents; Counsel. The Agent shall be entitled to
rely upon any Note, notice, consent, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to
legal matters, upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

        10.8.  Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Lenders, in connection with the preparation,
execution, delivery, administration and enforcement of the Loan Documents
(including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Lender or between two or
more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of the Loan
Documents or any other document delivered in connection therewith or the
transactions contemplated thereby (including, without limitation, for any such
amounts incurred by or asserted against the Agent in connection with any dispute
between the Agent and any Lender or between two or more of the Lenders), or the
enforcement of any of the terms of the Loan Documents





<PAGE>   50


or of any such other documents, provided that (i) no Lender shall be liable for
any of the foregoing to the extent any of the foregoing is found in a final
non-appealable judgment by a court of competent jurisdiction to have resulted
from the gross negligence or willful misconduct of the Agent and (ii) any
indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the
provisions of this Section 10.8, be paid by the relevant Lender in accordance
with the provisions thereof. The obligations of the Lenders under this Section
10.8 shall survive payment of the Obligations and termination of this Agreement.

      10.9.   Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Unmatured Default hereunder unless
the Agent has received written notice from a Lender or the Borrower referring to
this Agreement describing such Default or Unmatured Default and stating that
such notice is a "notice of default". In the event that the Agent receives such
a notice, the Agent shall give prompt notice thereof to the Lenders.

      10.10.  Rights as a Lender. In the event the Agent is a Lender, the Agent
shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The Agent and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of trust, debt, equity or other transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or
any of its Subsidiaries in which the Borrower or such Subsidiary is not
restricted hereby from engaging with any other Person.

      10.11.  Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger or any other
Lender and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and the other Loan
Documents. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent, the Arranger or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement and the other Loan Documents.

      10.12.  Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. The Agent may be removed at any time with or without cause
by written notice received by the Agent from the Required Lenders, such removal
to be effective on the date specified by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint, on
behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent
shall have been so appointed by the Required Lenders within thirty days after
the resigning Agent's giving notice of its intention to resign, then the
resigning Agent may appoint, on behalf of the Borrower and the Lenders, a
successor Agent. Notwithstanding the previous sentence, the Agent may at any
time without the consent of the Borrower or any Lender, appoint any of its
Affiliates which is a commercial bank as a successor Agent hereunder. If the
Agent has resigned or been removed and no successor Agent has been appointed,
the Lenders may perform all the duties of the Agent hereunder and the Borrower
shall make all payments in respect of the Obligations to the applicable Lender
and for all other purposes shall deal directly with the Lenders. No successor
Agent shall be deemed to be appointed hereunder until such successor Agent has
accepted the appointment. Any such successor Agent shall be a commercial bank
having capital and retained earnings of at least $100,000,000. Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and
under the Loan Documents. After the effectiveness of the resignation or removal
or removal of an Agent, the provisions of this Article X shall continue in
effect for the
<PAGE>   51
benefit of an Agent, the provisions of this Article X shall continue in effect
for the benefit of such Agent in respect of any actions taken or omitted to be
taken by it while it was acting as the Agent hereunder and under the other Loan
Documents. In the event that there is a successor to the Agent by merger, or the
Agent assigns its duties and obligations to an Affiliate pursuant to this
Section 10.12, then the term "Prime Rate" as used in this Agreement shall mean
the prime rate, base rate or other analogous rate of the new Agent.

        10.13. Agent's Fee; Etc.. The Borrower agrees to pay to the Agent, for
its own account, the amounts agreed to by the Borrower and the Agent pursuant to
separate agreements from time to time.

        10.14. Delegation to Affiliates. The Borrower and the Lenders agree that
the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this Agreement shall be
entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Agent is entitled under Articles IX and X.

        10.15. Execution of Collateral Documents. The Lenders hereby empower and
authorize the Agent to execute and deliver to the Borrower on their behalf the
Collateral Documents and all related financing statements and any financing
statements, agreements, documents or instruments as shall be necessary or
appropriate to effect the purposes of the Collateral Documents.

        10.16. Collateral Releases. The Lenders hereby empower and authorize the
Agent to execute and deliver to the Borrower on their behalf any agreements,
documents or instruments as shall be necessary or appropriate to effect any
releases of Collateral which shall be permitted by the terms hereof or of any
other Loan Document or which shall otherwise have been approved by the Required
Lenders (or, if required by the terms of Section 8.2, all of the Lenders) in
writing.

        10.17. Co-Agents, Documentation Agent, Syndication Agent, etc. No Lender
identified in this Agreement or otherwise as a "Documentation Agent"
"Syndication Agent" nor "Co-Agent" have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of such Lenders shall have
or be deemed to have a fiduciary relationship with any Lender. Each Lender
hereby makes the same acknowledgments with respect to such Lenders as it makes
with respect to the Agent in Section 10.11.


                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS


        11.1. Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs and is continuing, any and all deposits
(including all account balances, whether provisional or final and whether or not
collected or available) and any other Indebtedness at any time held or owing by
any Lender or any Affiliate of any Lender to or for the credit or account of the
Borrower may be offset and applied toward the payment of the Obligations owing
to such Lender, whether or not the Obligations, or any part hereof, shall then
be due.

        11.2. Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Outstanding Credit Exposure (other than payments
received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than
that received by any other Lender, such Lender agrees, promptly upon demand, to
purchase a portion of the Aggregate Outstanding Credit Exposure held by the
other Lenders so that after such purchase each Lender will hold its Pro Rata
Share of the Aggregate Outstanding Credit Exposure. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligations or such amounts
which may be subject to setoff, such Lender agrees, promptly upon demand, to
take such action necessary such that all Lenders share in



<PAGE>   52

the benefits of such collateral ratably in proportion to their respective Pro
Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such
payment is disturbed by legal process, or otherwise, appropriate further
adjustments shall be made. If an amount to be setoff is to be applied to
Indebtedness of the Borrower to a Lender other than Indebtedness comprised of
the Outstanding Credit Exposure of such Lender, such amount shall be applied
ratably to such other Indebtedness and to the Indebtedness comprised of such
Outstanding Credit Exposure.


                                  ARTICLE XII

               BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS


        12.1. Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents (other than pursuant to the merger with Zenith as contemplated
hereunder and the assumption of all Secured Obligations and other obligations
under the Loan Documents by Zenith in connection therewith) and (ii) any
assignment by any Lender must be made in compliance with Section 12.3.
Notwithstanding clause (ii) of this Section, any Lender may at any time, without
the consent of the Borrower or the Agent, assign all or any portion of its
rights under this Agreement and any Note to a Federal Reserve Bank; provided,
however, that no such assignment to a Federal Reserve Bank shall release the
transferor Lender from its obligations hereunder. The Agent may treat the Person
which made any Loan or which holds any Note as the owner thereof for all
purposes hereof unless and until such Person complies with Section 12.3 in the
case of an assignment thereof or, in the case of any other transfer, a written
notice of the transfer is filed with the Agent. Any assignee or transferee of
the rights to any Loan or any Note agrees by acceptance of such transfer or
assignment to be bound by all the terms and provisions of the Loan Documents.
Any request, authority or consent of any Person, who at the time of making such
request or giving such authority or consent is the owner of the rights to any
Loan (whether or not a Note has been issued in evidence thereof), shall be
conclusive and binding on any subsequent holder, transferee or assignee of the
rights to such Loan.

        12.2.   Participations.

                12.2.1. Permitted Participants; Effect. Any Lender may, in the
ordinary course of its business and in accordance with applicable law, at any
time sell to one or more banks or other entities ("Participants") participating
interests in any Outstanding Credit Exposure of such Lender, any Note held by
such Lender, any Commitment of such Lender or any other interest of such Lender
under the Loan Documents. In the event of any such sale by a Lender of
participating interests to a Participant, such Lender's obligations under the
Loan Documents shall remain unchanged, such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
such Lender shall remain the owner of its Outstanding Credit Exposure and the
holder of any Note issued to it in evidence thereof for all purposes under the
Loan Documents, all amounts payable by the Borrower under this Agreement shall
be determined as if such Lender had not sold such participating interests, and
the Borrower and the Agent shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under the Loan
Documents.

                12.2.2. Voting Rights. Each Lender shall retain the sole right
to approve, without the consent of any Participant, any amendment, modification
or waiver of any provision of the Loan Documents other than any amendment,
modification or waiver with respect to any Credit Extension or Commitment in
which such Participant has an interest which forgives principal, interest, or
any Reimbursement Obligation or reduces the interest rate or fees payable with
respect to any such Credit Extension or Commitment, extends the Facility
Termination Date, postpones any date fixed for any regularly-scheduled payment
of principal of or interest on any Loan in which such Participant has an
interest, or any regularly-scheduled payment of fees on any such Credit
Extension or


<PAGE>   53

Commitment, releases any guarantor of any such Credit Extension or
releases any collateral held in the Facility LC Collateral Account (except in
accordance with the terms hereof) or all or substantially all of any other
collateral, if any, securing any such Credit Extension.

                12.2.3. Benefit of Setoff. The Borrower agrees that each
Participant shall be deemed to have the right of setoff provided in Section 11.1
in respect of its participating interest in amounts owing under the Loan
Documents to the same extent as if the amount of its participating interest were
owing directly to it as a Lender under the Loan Documents, provided that each
Lender shall retain the right of setoff provided in Section 11.1 with respect to
the amount of participating interests sold to each Participant. The Lenders
agree to share with each Participant, and each Participant, by exercising the
right of setoff provided in Section 11.1, agrees to share with each Lender, any
amount received pursuant to the exercise of its right of setoff, such amounts to
be shared in accordance with Section 11.2 as if each Participant were a Lender.

        12.3.   Assignments.

                12.3.1. Permitted Assignments. Any Lender may, in the ordinary
course of its business and in accordance with applicable law, at any time assign
to one or more banks or other entities ("Purchasers") all or any part of its
rights and obligations under the Loan Documents. Such assignment shall be
substantially in the form of Exhibit C or in such other form as may be agreed to
by the parties thereto. The consent of the Borrower and the Agent shall be
required prior to an assignment becoming effective with respect to a Purchaser
which is not a Lender or an Affiliate thereof; provided, however, that if a
Default has occurred and is continuing or if such assignment is to another
Lender or an Affiliate of a Lender, the consent of the Borrower shall not be
required. Such consent shall not be unreasonably withheld or delayed. Each such
assignment with respect to a Purchaser which is not a Lender or an Affiliate
thereof shall (unless each of the Borrower and the Agent otherwise consents) be
in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining
amount of the assigning Lender's Commitment (calculated as at the date of such
assignment) or outstanding Loans (if the applicable Commitment has been
terminated).

                12.3.2. Effect; Effective Date. Upon (i) delivery to the Agent
of an assignment, together with any consents required by Section 12.3.1, and
(ii) payment of a $4,000 fee to the Agent for processing such assignment (unless
such fee is waived by the Agent), such assignment shall become effective on the
effective date specified in such assignment. The assignment shall contain a
representation by the Purchaser to the effect that none of the consideration
used to make the purchase of the Commitment and Outstanding Credit Exposure
under the applicable assignment agreement constitutes "plan assets" as defined
under ERISA and that the rights and interests of the Purchaser in and under the
Loan Documents will not be "plan assets" under ERISA. On and after the effective
date of such assignment, such Purchaser shall for all purposes be a Lender party
to this Agreement and any other Loan Document executed by or on behalf of the
Lenders and shall have all the rights and obligations of a Lender under the Loan
Documents, to the same extent as if it were an original party hereto, and no
further consent or action by the Borrower, the Lenders or the Agent shall be
required to release the transferor Lender with respect to the percentage of the
Aggregate Commitment and Outstanding Credit Exposure assigned to such Purchaser.
Upon the consummation of any assignment to a Purchaser pursuant to this Section
12.3.2, the transferor Lender, the Agent and the Borrower shall, if the
transferor Lender or the Purchaser desires that its Loans be evidenced by Notes,
make appropriate arrangements so that new Notes or, as appropriate, replacement
Notes are issued to such transferor Lender and new Notes or, as appropriate,
replacement Notes, are issued to such Purchaser, in each case in principal
amounts reflecting their respective Commitments, as adjusted pursuant to such
assignment.

        12.4. Dissemination of Information. The Borrower authorizes each Lender
to disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the


<PAGE>   54


Borrower and its Subsidiaries, including without limitation any information
contained in any Reports; provided that each Transferee and prospective
Transferee agrees to be bound by Section 9.11 of this Agreement.

        12.5. Tax Treatment. If any interest in any Loan Document is transferred
to any Transferee which is organized under the laws of any jurisdiction other
than the United States or any State thereof, the transferor Lender shall cause
such Transferee, concurrently with the effectiveness of such transfer, to comply
with the provisions of Section 3.5(iv).



                                  ARTICLE XIII

                                    NOTICES


        13.1. Notices. Except as otherwise permitted by Section 2.14 with
respect to borrowing notices, all notices, requests and other communications to
any party hereunder shall be in writing (including electronic transmission,
facsimile transmission or similar writing) and shall be given to such party: (x)
in the case of the Borrower or the Agent, at its address or facsimile number set
forth on the signature pages hereof, (y) in the case of any Lender, at its
address or facsimile number set forth in its administrative questionnaire or (z)
in the case of any party, at such other address or facsimile number as such
party may hereafter specify for the purpose by notice to the Agent and the
Borrower in accordance with the provisions of this Section 13.1. Each such
notice, request or other communication shall be effective (i) if given by
facsimile transmission, when transmitted to the facsimile number specified in
this Section and confirmation of receipt is received, (ii) if given by mail, 72
hours after such communication is deposited in the mails with first class
postage prepaid, addressed as aforesaid, or (iii) if given by any other means,
when delivered (or, in the case of electronic transmission, received) at the
address specified in this Section; provided that notices to the Agent under
Article II shall not be effective until received.

        13.2. Change of Address. The Borrower, the Agent and any Lender may each
change the address for service of notice upon it by a notice in writing to the
other parties hereto.



                                  ARTICLE XIV

                                  COUNTERPARTS


        This Agreement may be executed in any number of counterparts, all of
which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Borrower, the
Agent, the LC Issuer and the Lenders and each party has notified the Agent by
facsimile transmission or telephone that it has taken such action.

CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE
STATE OF MICHIGAN.

        15.2. CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY SUBMITS
TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR MICHIGAN STATE
COURT SITTING IN DETROIT, MICHIGAN IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES THAT
ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED
IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER
HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A
COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT
THE RIGHT OF THE AGENT, THE LC ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST
THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY
THE BORROWER AGAINST THE AGENT, THE LC ISSUER OR ANY LENDER OR ANY AFFILIATE OF
THE AGENT, THE LC ISSUER OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY
MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN
DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN DETROIT, MICHIGAN.

        15.3. WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT, THE LC ISSUER AND
EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING,
DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR
OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN
DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

        For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

        "Financials" means the annual or quarterly financial statements of the
Borrower delivered pursuant to Section 6.1(i) or (ii).

        "Level I Status" exists at any date if, as of the last day of the fiscal
quarter of the Borrower referred to in the most recent Financials, the Leverage
Ratio is less than 2.75 to 1.00.

        "Level II Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, (i)
the Borrower has not qualified for Level I Status and (ii) the Leverage Ratio is
less than or equal to 3.25 to 1.00.

        "Level III Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, (i)
the Borrower has not qualified for Level I Status or Level II Status and (ii)
the Leverage Ratio is less than 3.75 to 1.00.

        "Level IV Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, (i)
the Borrower has not qualified for Level I Status, Level II Status or Level III
Status and (ii) the Leverage Ratio is less than 4.25 to 1.00.

        "Level V Status" exists at any date if the Borrower has not qualified
for Level I Status, Level II Status, Level III Status or Level IV Status.

        "Status" means either Level I Status, Level II Status, Level III Status,
Level IV Status or Level V Status.

        The Applicable Margin and Applicable Fee Rate shall be determined in
accordance with the foregoing table based on the Borrower's Status as reflected
in the then most recent Financials. Adjustments, if any, to the Applicable
Margin or Applicable Fee Rate shall be effective 60 days after the end of each
fiscal quarter. If the Borrower fails to deliver the Financials to the Agent at
the time required pursuant to Section 6.1 or any other Default has occurred and
is continuing, then the Applicable Margin and Applicable Fee Rate shall be the
highest Applicable Margin and Applicable Fee Rate set forth in the foregoing
table until such Default is cured or waived under the Agreement. Notwithstanding
the foregoing, the Applicable Margin for the period from the date hereof until
it shall be adjusted for the first time based on the results for the fiscal
quarter ending September 30, 1999 shall be the Applicable Margin assuming the

                                   EXHIBIT A

                                FORM OF OPINION

                                                       July 13, 1999

The Agent, the LC Issuer and the Lenders who are parties to the Credit Agreement
described below.

Gentlemen/Ladies:

        We are counsel for 20 20 Corp. 70 (the "Borrower") and the Guarantors,
and have represented the Borrower in connection with its execution and delivery
of a Credit Agreement dated as of July 13, 1999 (the "Agreement") among the
Borrower, the Lenders named therein, and Bank One, Michigan, as Agent, and as LC
Issuer. All capitalized terms used in this opinion and not otherwise defined
herein shall have the meanings attributed to them in the Agreement.

        We have examined the Borrower's and each Guarantor's organizational
documents and appropriate evidence of authority to enter into the transaction,
the Loan Documents and such other matters of fact and law which we deem
necessary in order to render this opinion. Based upon the foregoing, it is our
opinion that:

        l. Each of the Borrower and its Subsidiaries and each other Guarantor is
a corporation, partnership or limited liability company duly and properly
incorporated or organized, as the case may be, validly existing and (to the
extent such concept applies to such entity) in good standing under the laws of
its jurisdiction of incorporation or organization and has all requisite
authority to conduct its business in each jurisdiction in which its business is
conducted.

        2. The execution and delivery by each of the Borrower and each Guarantor
of the Loan Documents to which it is a party and the performance by each of the
Borrower and each Guarantor of its obligations thereunder have been duly
authorized by proper corporate proceedings on the part of the Borrower and each
Guarantor and will not:

           (a) require any consent of the Borrower's or any Guarantor's
shareholders or members (other than any such consent as has already been given
and remains in full force and effect);

           (b) violate (i) any law, rule, regulation, order, writ, judgment,
injunction, decree or award binding on the Borrower or any of its Subsidiaries
or (ii) the Borrower's or any Subsidiary's articles or certificate of
incorporation, partnership agreement, certificate of partnership, articles or
certificate of organization, by-laws, or operating or other management
agreement, as the case may be, or (iii) the provisions of any indenture,
instrument or agreement to which the Borrower or any of its Subsidiaries is a
party or is subject, or by which it, or its Property, is bound, or conflict with
or constitute a default thereunder; or

           (c) result in, or require, the creation or imposition of any Lien in,
of or on the Property of the Borrower or a Subsidiary pursuant to the terms of
any indenture, instrument or agreement binding upon the Borrower or any of its
Subsidiaries.

        3. The Loan Documents to which the Borrower and each Guarantor is a
party have been duly executed and delivered by the Borrower and each Guarantor
and constitute legal, valid and binding obligations of the Borrower and each
Guarantor enforceable against the Borrower and each Guarantor in accordance with
their terms except to the extent the enforcement thereof may be limited by
bankruptcy, insolvency or similar laws affecting the enforcement of creditors'
rights generally and subject also to the availability of equitable remedies if
equitable remedies are sought.




<PAGE>   61

        4. There is no litigation, arbitration, governmental investigation,
proceeding or inquiry pending or, to the best of our knowledge after due
inquiry, threatened against the Borrower or any of its Subsidiaries which, if
adversely determined, could reasonably be expected to have a Material Adverse
Effect.

        5. No order, consent, adjudication, approval, license, authorization, or
validation of, or filing, recording or registration with, or exemption by, or
other action in respect of any governmental or public body or authority, or any
subdivision thereof, which has not been obtained by the Borrower or any of its
Subsidiaries, is required to be obtained by the Borrower or any of its
Subsidiaries in connection with the execution and delivery of the Loan
Documents, the borrowings under the Agreement, the payment and performance by
the Borrower and each Guarantor of the Obligations, or the legality, validity,
binding effect or enforceability of any of the Loan Documents.

        6. All Secured Obligations are senior debt under the Subordinated Debt
Documents and are entitled to the benefits of the subordination provisions of
the Subordinated Debt Documents. The Subordinated Debt Documents to which the
Borrower is a party have been duly executed and delivered by the Borrower and
constitute legal, valid and binding obligations of the Borrower enforceable
against the Borrower in accordance with their terms except to the extent the
enforcement thereof may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally and subject also to the
availability of equitable remedies if equitable remedies are sought.

        7. The provisions of the Collateral Documents are sufficient to create
in favor of the Lenders a security interest in all right, title and interest of
the Borrower and each Guarantor in those items and types of collateral described
in the Collateral Documents in which a security interest may be created under
Article 9 of the Uniform Commercial Code as in effect on the date hereof in
Michigan. Financing statements on Form UCC-1's have been duly executed by the
Borrower and each Guarantor and have been duly filed in each filing office
indicated in Exhibit A hereto under the Uniform Commercial Code in effect in
each state in which said filing offices are located. The description of the
collateral set forth in said financing statements is sufficient to perfect a
security interest in the items and types of collateral described therein in
which a security interest may be perfected by the filing of a financing
statement under the Uniform Commercial Code as in effect in such states. Such
filings are sufficient to perfect the security interest created by the
Collateral Documents in all right, title and interest of the Borrower and each
Guarantor in those items and types of collateral described in the Collateral
Documents in which a security interest may be perfected by the filing of a
financing statement under the Uniform Commercial Code in such states, except
that we express no opinion as to personal property affixed to real property in
such manner as to become a fixture under the laws of any state in which the
collateral may be located and we call your attention to the fact that the
Lenders' security interest in certain of such collateral may not be perfected by
filing financing statements under the Uniform Commercial Code.

        8. Upon payment for the Capital Stock of Zenith pursuant to the Zenith
Acquisition Documents, the Borrower will acquire, free and clear of any Lien,
100% of the Capital Stock of Zenith. On the date hereof, the Borrower and Zenith
have merged, and Zenith is the surviving entity and has assumed all Secured
Obligations and all other obligations and liabilities of the Borrower under the
Loan Documents. The opinion in this paragraph 8 assumes that the Borrower does
not have notice of any adverse claim with respect to the Capital Stock of
Zenith.

        9. The Mortgages are in proper form for the creation of the liens and
security interests contemplated thereby and for recording in the real property
records of the recording office in the County in which the Real Property is
located. The Mortgages create a valid and perfected mortgage lien and security
interest in the real and other property described in each Mortgage.

        This opinion may be relied upon by the Agent, the LC Issuer the Lenders
and their participants, assignees and other transferees.

                                Very truly yours,
