         amount is not in fact made available to Agent by such Bank in
         accordance with Section 2.4(a), as aforesaid, Agent shall be entitled
         to recover such amount on demand from such Bank. If such Bank does not
         pay such amount forthwith upon Agent's demand therefor, the Agent shall
         promptly notify Company, and Company shall pay such amount to Agent.
         Agent shall also be entitled to recover from such Bank or from Company,
         as the case may be but without duplication, interest on such amount in
         respect of each day from the date such amount was made available by
         Agent to Company to the date such amount is recovered by Agent, at a
         rate per annum equal to:

               (i)    in the case of such Bank, the Federal Funds Effective Rate
                      for the first two (2) Business Days such amount remains
                      unpaid and at the rate of interest applicable to the
                      Revolving Credit Advances thereafter; or



                                       19
<PAGE>   27




               (ii)   in the case of Company, the rate of interest then
                      applicable to the Revolving Credit Advance.

         The obligation of any Bank to make any Revolving Credit Advance
         hereunder shall not be affected by the failure of any other Bank to
         make any Revolving Credit Advance hereunder, and no Bank shall have any
         liability to the Company, the Agent, any other Bank, or any other party
         for another Bank's failure to make any loan or Revolving Credit Advance
         hereunder.

         2.5 Prime-based Advance in Absence of Election or Upon Default. If, as
to any outstanding Eurocurrency-based Advance, Agent has not received payment on
the last day of the Interest Period applicable thereto, or does not receive a
timely Request for Revolving Credit Advance meeting the requirements of Section
2.3 hereof with respect to the refunding or conversion of such Advance, or,
subject to Section 5.6 hereof, if on such day a Default or Event of Default
shall exist, the principal amount thereof which is not then prepaid shall be
converted automatically to a Prime-based Advance and the Agent shall thereafter
promptly notify Company of said action.

         2.6 Revolving Credit Facility Fee. From the Effective Date to the
Revolving Credit Maturity Date, the Company shall pay to the Agent on behalf of
Banks a Revolving Credit Facility Fee quarterly in arrears commencing October 1,
1998 (in respect of the prior fiscal quarter or portion thereof), and on the
first day of each fiscal quarter thereafter. The Revolving Credit Facility Fee
shall be the sum of the fifteen one hundredths of one percent (.15%) per annum
multiplied by Revolving Credit Aggregate Commitment (whether used or unused)
then in effect without giving effect to any reductions therein based on the
amount of the Environmental Reserve, computed on a daily basis. The Revolving
Credit Facility Fee shall be computed on the basis of a year of three hundred
sixty (360) days and assessed for the actual number of days elapsed. Whenever
any payment of the Revolving Credit Facility Fee shall be due on a day which is
not a Business Day, the date for payment thereof shall be extended to the next
Business Day. Upon receipt of such payment, Agent shall make prompt payment to
each Bank of its share of the Revolving Credit Facility Fee based upon its
respective Percentage. It is expressly understood that the Revolving Credit
Facility Fees described in this Section are not refundable under any
circumstances.

         2.7 Reduction of Indebtedness; Revolving Credit Aggregate Commitment.
If at any time and for any reason the aggregate principal amount of Revolving
Credit Advances hereunder to Company, plus the Letter of Credit Obligations
which shall be outstanding at such time, shall exceed the Revolving Credit
Aggregate Commitment then in effect, the Company shall immediately reduce any
pending request for an Advance on such day by the amount of such excess and, to
the extent any excess remains thereafter, immediately repay an amount of the
Indebtedness equal to such excess and, to the extent such Indebtedness consists
of Letter of Credit Obligations, provide cash collateral on the basis set forth
in Section 10.2 hereof. Company acknowledges that, in connection with any
repayment required hereunder, it shall also be responsible for the reimbursement
of any prepayment or other costs required under Section 12.1 hereof; provided,
however, that Company shall, in order to reduce any such prepayment costs and
expenses, first prepay such portion of the Indebtedness then carried as a
Prime-based Advance, if any.




                                       20
<PAGE>   28




         2.8 Optional Reduction or Termination of Revolving Credit Aggregate
Commitment. The Company may, upon at least five (5) Business Days' prior written
notice to Agent, permanently reduce the Revolving Credit Aggregate Commitment in
whole at any time, or in part from time to time, without premium or penalty,
provided that: (i) each partial reduction of the Revolving Credit Aggregate
Commitment shall be in an aggregate amount equal to at least Two Million Dollars
($2,000,000) or a larger integral multiple of One Million Dollars ($1,000,000);
(ii) each reduction shall be accompanied by the payment of the Revolving Credit
Facility Fee, if any, accrued to the date of such reduction; (iii) the Company
shall prepay in accordance with the terms hereof the amount, if any, by which
the sum of the aggregate unpaid principal amount of Revolving Credit Advances,
plus the Letter of Credit Obligations, exceeds the then applicable Revolving
Credit Aggregate Commitment, taking into account the aforesaid reductions
thereof, together with accrued but unpaid interest on the principal amount of
such prepaid Advances to the date of prepayment; (iv) if the termination or
reduction of the Revolving Credit Aggregate Commitment requires the prepayment
of a Eurocurrency-based Advance, the termination or reduction may be made only
on the last Business Day of the then current Interest Period applicable to such
Advance; and (v) no reduction shall reduce the amount of the Revolving Credit
Aggregate Commitment to an amount which is less than the Letter of Credit
Obligations at such time. Reductions of the Revolving Credit Aggregate
Commitment and any accompanying prepayments of the Revolving Credit Notes shall
be distributed by Agent to each Bank in accordance with such Bank's Percentage
thereof, and will not be available for reinstatement by or readvance to the
Company. Any reductions of the Revolving Credit Aggregate Commitment hereunder
shall reduce each Bank's portion thereof proportionately (based upon the
applicable Percentages), and shall be permanent and irrevocable. Any payments
made pursuant to this Section shall be applied first to outstanding Prime-based
Advances under the Revolving Credit and then to Eurocurrency-based Advances.

         2.9 Extension of Revolving Credit Maturity Date. (a) Provided that no
Default or Event of Default has occurred and is continuing, Company may, by
written notice to Agent (with sufficient copies for each Bank) (which notice
shall be irrevocable and which shall not be deemed effective unless actually
received by Agent) prior to April 1st, but not before March 1st, of each fiscal
year, request that the Banks extend the then applicable Revolving Credit
Maturity Date to a date that is one year later than the Revolving Credit
Maturity Date then in effect (each such request, a "Request"). Each Bank shall,
not later than May 31st of such fiscal year, give written notice to the Agent
stating whether such Bank is willing to extend the Revolving Credit Maturity
Date as requested. If Agent has received the aforesaid written approvals of such
Request from each of the Banks, then, effective upon the date of Agent's receipt
of all such written approvals from the Banks, as aforesaid, the Revolving Credit
Maturity Date shall be so extended for an additional one year period, the term
Revolving Credit Maturity Date shall mean such extended date and Agent shall
promptly notify the Company that such extension has occurred.

             (b) If (i) any Bank gives the Agent written notice that it is
unwilling to extend the Revolving Credit Maturity Date as requested or (ii) any
Bank fails to provide written approval to Agent of such a Request on or before
May 31st of such fiscal year, then (w) the Banks shall be



                                       21
<PAGE>   29

deemed to have declined to extend the Revolving Credit Maturity Date, (x) the
then-current Revolving Credit Maturity Date shall remain in effect (with no
further right on the part of Company to request extensions thereof under this
Section 2.9), and (y) the commitments of the Banks to make Advances of the
Revolving Credit hereunder shall terminate on the Revolving Credit Maturity Date
then in effect, and Agent shall promptly notify Company thereof.

         Bank and its Issuing Office;

             (g) no order, judgment or decree of any court, arbitrator or
         governmental authority shall purport by its terms to enjoin or restrain
         Issuing Bank from issuing the requested Letter of Credit, or any Bank
         from taking an assignment of its Percentage thereof pursuant to Section
         3.6 hereof, and no law, rule, regulation, request or directive (whether

         assignment of its Percentage of, the Letter of Credit requested or
         letters of credit generally; 

             (h) there shall have been no introduction of or change in the

         requested Letter of Credit are located (each a "Banking Authority"),
         and no establishment of any new material restrictions by any Banking

         connection with the issuance of such Letter of Credit pursuant to
         Section 3.4(b) hereof.

entitled to rely on such certification without any duty of inquiry.

<PAGE>   31

Promptly upon its receipt thereof, Agent shall give notice, substantially in the
form attached as Exhibit C, to each Bank of the issuance of each Letter of
Credit, specifying the amount thereof and the amount of such Bank's Percentage
thereof.

         3.4 Letter of Credit Fees. Company shall pay to the Agent for
distribution to the Issuing Bank and the Banks in accordance with the
Percentages, Letter of Credit Fees as follows:

             (a) A per annum Letter of Credit Fee with respect to the undrawn
         amount of each Letter of Credit issued pursuant hereto in the amount of
         the Applicable L/C Fee Percentage (determined with reference to
         Schedule 1.1 of this Agreement), exclusive of the facing fee to be
         paid to Issuing Bank under Section 3.4(b) hereof.

             (b) A facing fee of the lesser of (i) one eighth percentage point
         (1/8%) per annum on the undrawn amount of each Letter of Credit or (ii)
         $500.00, to be paid by the Company to the Issuing Bank for its own
         account.

             (c) If any change in any law or regulation or in the interpretation
         thereof by any court or administrative or governmental authority
         charged with the administration thereof shall either (i) impose, modify
         or cause to be deemed applicable any reserve, special deposit,
         limitation or similar requirement against letters of credit issued by
         or participated in, or assets held by, or deposits in or for the
         account of, Issuing Bank or any Bank or (ii) impose on Issuing Bank or
         any of the Banks any other condition regarding this Agreement or the
         Letters of Credit, and the result of any event referred to in clause
         (i) or (ii) above shall be to increase in an amount deemed material by
         Issuing Bank or such Bank the cost or expense to Issuing Bank or the
         Banks of issuing or maintaining or participating in any of the Letters
         of Credit (which increase in cost or expense shall be determined by the
         Issuing Bank's or such Bank's reasonable allocation of the aggregate of
         such cost increases and expense resulting from such events), then, upon
         demand by the Issuing Bank or such Bank, as the case may be, the
         Company shall, within thirty days following demand for payment, pay to
         Issuing Bank or such Bank, as the case may be, from time to time as
         specified by the Issuing Bank or such Bank, additional amounts which
         shall be sufficient to compensate the Issuing Bank or such Bank for
         such increased cost and expense, together with interest on each such
         amount from thirty days after the date demanded until payment in full
         thereof at the Prime-based Rate. A certificate as to such increased
         cost or expense incurred by the Issuing Bank or such Bank, as the case
         may be, as a result of any event mentioned in clause (i) or (ii) above,
         shall be promptly submitted to the Company and shall be conclusive
         evidence, absent manifest error, as to the amount thereof.

             (d) All payments by the Company to the Agent for distribution to
         the Issuing Bank or the Banks under this Section 3.4 shall be made in
         Dollars and in immediately available funds at the principal office of
         the Agent or such other office of the Agent as may be designated from

         described in clause (a) above shall be nonrefundable under all
         circumstances and shall be



                                       24
<PAGE>   32

         payable quarterly in advance (or such lesser period, if applicable, for
         Letters of Credit issued with stated expiration dates of less than one
         year) upon the issuance of each such Letter of Credit, and shall be
         calculated on the basis of a 360 day year and assessed for the actual
         number of days from the date of the issuance thereof to the stated
         expiration thereof.

         3.5 Other Letter of Credit Fees. In connection with the Letters of
Credit, and in addition to the Letter of Credit Fees, the Company and the
applicable Account Party shall pay, for the sole account of the Issuing Bank,
standard documentation, administration, payment and cancellation charges
assessed by Issuing Bank or its Issuing Office, at the times, in the amounts and
on the terms set forth or to be set forth from time to time in the standard fee
schedule of Issuing Office in effect from time to time.

         3.6 Draws and Demands for Payment Under Letters of Credit.

             (a) The Company and each applicable Account Party agree to pay to
         the Agent for the account of the Issuing Bank, on the day on which the
         Issuing Bank shall honor a draft or other demand for payment presented
         or made under any Letter of Credit, an amount equal to the amount paid
         by the Issuing Bank in respect of such draft or other demand under such
         Letter of Credit and all reasonable expenses paid or incurred by the
         Issuing Bank relative thereto. Unless the Company or the applicable
         Account Party shall have made such payment to the Agent for the account
         of the Issuing Bank on such day, upon each such payment by the Issuing
         Bank, the Agent shall be deemed to have disbursed to the Company, and
         the Company shall be deemed to have elected to substitute for its
         Reimbursement Obligation, a Prime-based Advance from the Banks in an
         amount equal to the amount so paid by the Issuing Bank in respect of
         such draft or other demand under such Letter of Credit. Such
         Prime-based Advance shall be disbursed notwithstanding any failure to
         satisfy any conditions for disbursement of any Advance set forth in
         Article 2 hereof and, to the extent of the Prime-based Advance so
         disbursed, the Reimbursement Obligation of the Company or the
         applicable Account Party to the Agent under this Section 3.6 shall be
         deemed satisfied.

             (b) If the Issuing Bank shall honor a draft or other demand for
         payment presented or made under any Letter of Credit, the Issuing Bank
         shall provide notice thereof to the Company and the applicable Account
         Party on the date such draft or demand is honored, and to each Bank on
         such date unless the Company or applicable Account Party shall have
         satisfied its Reimbursement Obligation under Section 3.6(a) by payment
         to the Agent on such date. The Issuing Bank shall further use
         reasonable efforts to provide notice to the Company or applicable
         Account Party prior to honoring any such draft or other demand for
         payment, but such notice, or the failure to provide such notice, shall
         not affect the rights or obligations of the Issuing Bank with respect
         to any Letter of Credit or the rights and obligations of the parties
         hereto, including without limitation the obligations of the Company or
         applicable Account Party under Section 3.6(a) hereof




                                       25
<PAGE>   33




             (c) Upon issuance by the Issuing Bank of each Letter of Credit
         hereunder, each Bank shall automatically acquire a pro rata risk
         participation interest in such Letter of Credit and related Letter of
         Credit Payment based on its respective Percentage. Each Bank, on the
         date a draft or demand under any Letter of Credit is honored, shall
         make its Percentage share of the amount paid by the Issuing Bank, and
         not reimbursed by the Company or applicable Account Party by payment to
         the Agent on such day, available in immediately available funds at the
         principal office of the Agent for the account of the Issuing Bank. If
         and to the extent such Bank shall not have made such pro rata portion
         available to the Agent, such Bank, the Company and the applicable
         Account Party severally agree to pay to the Issuing Bank forthwith on
         demand such amount together with interest thereon, for each day from
         the date such amount was paid by the Issuing Bank until such amount is
         so made available to the Agent for the account of the Issuing Bank at a
         per annum rate equal to the interest rate applicable during such period
         to the related Advance disbursed under Section 3.6(a) in respect  of 
         the Reimbursement Obligation of the Company and the applicable Account
         Party. If such Bank shall pay such amount to the Agent for the account
         of the Issuing Bank together with such interest, such amount so paid
         shall constitute a Prime-based Advance by such Bank disbursed in
         respect of the Reimbursement Obligation of the Company or applicable
         Account Party under Section 3.6(a) for purposes of this Agreement,
         effective as of the date such amount was paid by the Issuing Bank. The
         failure of any Bank to make its pro rata portion of any such amount
         paid by the Issuing Bank available to the Agent for the account of the
         Issuing Bank shall not relieve any other Bank of its obligation to make
         available its pro rata portion of such amount, but no Bank shall be
         responsible for failure of any other Bank to make such pro rata portion
         available to the Agent for the account Issuing Bank.

             (d) Nothing in this Agreement shall be construed to require or
         authorize any Bank other than the Issuing Bank to issue any Letter of
         Credit, it being recognized that the Issuing Bank shall be the sole
         issuer of Letters of Credit under this Agreement.

         3.7 Obligations Irrevocable. The obligations of Company and any Account
Party to make payments to Agent for the account of the Issuing Bank or of the
Banks with respect to Reimbursement Obligations under Section 3.6 hereof, shall
be unconditional and irrevocable and not subject to any qualification or
exception whatsoever, including, without limitation:

             (a) Any lack of validity or enforceability of any Letter of Credit
         or any documentation relating to any Letter of Credit or to any
         transaction related in any way to such Letter of Credit (the "Letter of
         Credit Documents");

             (b) Any amendment, modification, waiver, consent, or any
         substitution, exchange or release of or failure to perfect any interest
         in collateral or security, with respect to any of the Letter of Credit
         Documents;

             (c) The existence of any claim, setoff, defense or other right
         which the Company or any Account Party may have at any time against any
         beneficiary or any transferee of any

                                       26
<PAGE>   34

         Letter of Credit (or any persons or entities for whom any such
         beneficiary or any such transferee may be acting), the Agent, the
         Issuing Bank or any other Bank or any other person or entity, whether
         in connection with any of the Letter of Credit Documents, the
         transactions contemplated herein or therein or any unrelated
         transactions;

             (d) Any draft or other statement or document presented under any
         Letter of Credit proving to be forged, fraudulent or invalid in any
         respect or any statement therein being untrue or inaccurate in any
         respect;

             (e) Absent gross negligence or willful misconduct on the part of
         the Issuing Bank or Banks, any failure, omission, delay or lack on the
         part of the Agent, the Issuing Bank or any other Bank or any party to
         any of the Letter of Credit Documents to enforce, assert or exercise

and payable, without presentment, notice or demand, all of which are hereby
expressly waived by Company; (c) upon the occurrence of any Event of Default
specified in subsection 9.1(j), above, and notwithstanding the lack of any
declaration by Agent under preceding clause (b), the entire unpaid principal
Indebtedness, including the Notes, shall become automatically and immediately
due and payable, and the Revolving Credit Aggregate Commitment shall be
automatically and immediately terminated; (d) the Agent shall, upon being
directed to do so by the Majority Banks, demand immediate delivery of cash
collateral, and the Company and each Account Party agrees to deliver such cash
collateral upon demand, in an amount equal to the maximum amount that may be

Banks or the Banks, as applicable (subject to the terms hereof), exercise any
remedy permitted by this Agreement, the other Loan Documents or law.

         9.3  Rights Cumulative. No delay or failure of Agent and/or Banks in
exercising any right, power or privilege hereunder shall affect such right,
power or privilege, nor shall any single or partial exercise thereof preclude
any further exercise thereof, or the exercise of any other power, right or
privilege. The rights of Agent and Banks under this Agreement are cumulative and
not exclusive of any right or remedies which Banks would otherwise have.

         9.4  Waiver by Company of Certain Laws. To the extent permitted by
applicable law, Company hereby agrees to waive, and does hereby absolutely and
irrevocably waive and relinquish the benefit and advantage of any valuation,
stay, appraisement, extension or redemption laws now existing or which may
hereafter exist, which, but for this provision, might be applicable to any sale
made under the judgment, order or decree of any court, on any claim for interest
on the Notes, or any security interest or mortgage contemplated by or granted
under or in connection with this Agreement. These waivers have been voluntarily
given, with full knowledge of the consequences thereof.

         9.5 Waiver of Defaults. No Event of Default shall be waived by the
Banks except in a writing signed by an officer of the Agent in accordance with
Section 13.11 hereof. No single or partial exercise of any right, power or
privilege hereunder, nor any delay in the exercise thereof, shall




                                       52
<PAGE>   60




preclude other or further exercise of their rights by Agent or the Banks. No
waiver of any Event of Default shall extend to any other or further Event of
Default. No forbearance on the part of the Agent or the Banks in enforcing any
of their rights shall constitute a waiver of any of their rights. Company
expressly agrees that this Section may not be waived or modified by the Banks or
Agent by course of performance, estoppel or otherwise.

         9.6  Set Off.

         Upon the occurrence and during the continuance of any Event of Default,
each Bank may at any time and from time to time, without notice to the Company
but subject to the provisions of Section 10.3 hereof, (any requirement for such
notice being expressly waived by the Company) set off and apply against any and
all of the obligations of the Company now or hereafter existing under this
Agreement, whether owing to such Bank or any other Bank or the Agent, any and
all deposits (general or special, time or demand, provisional or final) at any
time held and other indebtedness at any time owing by such Bank to or for the
credit or the account of the Company and any property of the Company from time
to time in possession of such Bank, irrespective of whether or not such deposits
held or indebtedness owing by such Bank may be contingent and unmatured and
regardless of whether any Collateral then held by Agent or any Bank is adequate
to cover the Indebtedness. Promptly following any such setoff, such Bank shall
give written notice to Agent and to Company of the occurrence thereof. The
Company hereby grants to the Banks and the Agent a lien on and security interest
in all such deposits, indebtedness and property as collateral security for the
payment and performance of all of the obligations of the Company under this
Agreement. The rights of each Bank under this Section 9.6 are in addition to the
other rights and remedies (including, without limitation, other rights of
setoff) which such Bank may have.

10.      PAYMENTS, RECOVERIES AND COLLECTIONS

         10.1 Payment Procedure.

              (a) All payments by Company of principal of, or interest on, the
         Notes, or of Fees, shall be made without setoff or counterclaim on the
         date specified for payment under this Agreement not later than 12:00
         noon (Detroit time) in immediately available funds to Agent, for the
         ratable account of the Banks, at Agent's office located at One Detroit
         Center, Detroit, Michigan 48226-3239, (care of Agent's Eurocurrency
         Lending Office, for Eurocurrency-based Advances). Upon receipt by the
         Agent of each such payment, the Agent shall make prompt payment in like
         funds received to each Bank as appropriate, or, in respect of
         Eurocurrency-based Advances, to such Bank's Eurocurrency Lending
         Office.

              (b) Unless the Agent shall have been notified by Company prior to
         the date on which any payment to be made by Company is due that Company
         does not intend to remit such payment, the Agent may, in its sole
         discretion and without obligation to do so, assume that the Company has
         remitted such payment when so due and the Agent may, in reliance upon
         such assumption, make available to each Bank on such payment date an
         amount equal



                                       53
<PAGE>   61




         to such Bank's share of such assumed payment. If Company has not in
         fact remitted such payment to the Agent each Bank shall forthwith on
         demand repay to the Agent the amount of such assumed payment made
         available or transferred to such Bank, together with the interest
         thereon, in respect of each day from and including the date such amount
         was made available by the Agent to such Bank to the date such amount is
         repaid to the Agent at a rate per annum equal to (i) for Prime-based
         Advances, the Federal Funds Effective Rate (daily average), as the same
         may vary from time to time, and (ii) with respect to Eurocurrency-based
         Advances, Agent's aggregate marginal cost (including the cost of
         maintaining any required reserves or deposit insurance and of any fees,
         penalties, overdraft charges or other costs or expenses incurred by
         Agent) of carrying such amount.

              (c) Subject to the definition of Interest Period, whenever any
         payment to be made hereunder shall otherwise be due on a day which is
         not a Business Day, such payment shall be made on the next succeeding
         Business Day and such extension of time shall be included in computing
         interest, if any, in connection with such payment.

              (d) All payments to be made by the Company under this Agreement or
         any of the Notes shall be made without set-off or counterclaim, as
         aforesaid, and without deduction for or on account of any present or
         future withholding or other taxes of any nature imposed by any
         governmental authority or of any political subdivision thereof or any
         federation or organization of which such governmental authority may at
         the time of payment be a member, unless Company is compelled by law to
         make payment subject to such tax. In such event, Company shall:

                  (i)   pay to the Agent for Agent's own account and/or, as the
                        case may be, for the account of the Banks such
                        additional amounts as may be necessary to ensure that
                        the Agent and/or such Bank or Banks receive a net amount
                        equal to the full amount which would have been
                        receivable had payment not been made subject to such
                        tax; and

                  (ii)  remit such tax to the relevant taxing authorities
                        according to applicable law, and send to the Agent or
                        the applicable Bank or Banks, as the case may be, such
                        certificates or certified copy receipts as the Agent or
                        such Bank or Banks shall reasonably require as proof of
                        the payment by the Company, of any such taxes payable by
                        the Company.

         As used herein, the terms "tax", "taxes" and "taxation" include all
existing or future income, stamp or other taxes (excluding, in the case of the
Agent and each Bank, net income and franchise taxes imposed on the Agent or such
Bank by the jurisdiction under the laws of which the Agent or such Bank is
organized or any political subdivision or taxing authority thereof or therein,
or by any jurisdiction in which such Bank's domestic lending office or
Eurocurrency Lending Office, as the case may be, is located or any political
subdivision or taxing authority thereof or therein) levies,



                                       54

<PAGE>   62




imposts, duties, charges, fees, deductions and withholdings and any restrictions
or conditions resulting in a charge together with interest thereon and fines and
penalties with respect thereto which may be imposed by reason of any violation
or default with respect to the law regarding such tax, assessed as a result of
or in connection with the transactions hereunder, or the payment and or receipt
of funds hereunder, or the payment or delivery of funds into or out of any
jurisdiction other than the United States (whether assessed against Company,
Agent or any of the Banks).

         10.2 Application of Proceeds of Collateral. Notwithstanding anything to
the contrary in this Agreement, after an Event of Default, the proceeds of any
Collateral, together with any offsets, voluntary payments by Company or any
Subsidiary or others and any other sums received or collected in respect of the
Indebtedness, shall be applied, first, to the Notes and any Reimbursement
Obligations on a pro rata basis (or in such order and manner as determined by
the Majority Banks; subject, however, to the applicable Percentages of the loans
held by each of the Banks), next, to any other Indebtedness on a pro rata basis,
and then, if there is any excess, to Company or the applicable Subsidiary, as
the case may be. The application of such proceeds and other sums to the Notes
and the Reimbursement Obligations shall be based on each Bank's Percentage of
the aggregate of the loans.

         10.3 Pro-rata Recovery. If any Bank shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of offset or otherwise)
on account of principal of, or interest on, any of the Indebtedness in excess of
its pro rata share of payments then or thereafter obtained by all Banks upon
principal of and interest on all Indebtedness, such Bank shall purchase from the
other Banks such participations in the Notes and/or Reimbursement Obligation
held by them as shall be necessary to cause such purchasing Bank to share the
excess payment or other recovery ratably in accordance with the Percentage with
each of them; provided, however, that if all or any portion of the excess
payment or other recovery is thereafter recovered from such purchasing holder,
the purchase shall be rescinded and the purchase price restored to the extent of
such recovery, but without interest.

11.      CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS

         11.1 Reimbursement of Prepayment Costs. If Company makes any payment of
principal with respect to any Eurocurrency-based Advance on any day other than
the last day of the Interest Period applicable thereto (whether voluntarily, by
acceleration, or otherwise), or if Company fails to borrow any 
Eurocurrency-based Advance after notice has been given by Company to Agent in
accordance with the terms hereof requesting such Advance, or if Company fails to
make any payment of principal or interest in respect of a Eurocurrency-based
Advance when due, then Company shall reimburse Agent and Banks, as the case may
be on demand for any resulting loss, cost or expense incurred by Agent and
Banks, as the case may be as a result thereof, including, without limitation,
any such loss, cost or expense incurred in obtaining, liquidating, employing or
redeploying deposits from third parties, whether or not Agent and Banks, as the
case may be shall have funded or committed to fund such Advance. Such amount
payable by Company to Agent and Banks, as the case may be may include, without
limitation, an amount equal to the excess, if any, of

                                       55
<PAGE>   63




(a) the amount of interest which would have accrued on the amount so prepaid, or
not so borrowed, refunded or converted, for the period from the date of such
prepayment or of such failure to borrow, refund or convert, through the last day
of the relevant Interest Period, at the applicable rate of interest for said
Advance(s) provided under this Agreement, over (b) the amount of interest (as
reasonably determined by Agent and Banks, as the case may be) which would have
accrued to Agent and Banks, as the case may be on such amount by placing such
amount on deposit for a comparable period with leading banks in the interbank
eurodollar market. Calculation of any amounts payable to any Bank under this
paragraph shall be made as though such Bank shall have actually funded or
committed to fund the relevant Advance through the purchase of an underlying
deposit in an amount equal to the amount of such Advance and having a maturity
comparable to the relevant Interest Period; provided, however, that any Bank may
fund any Eurocurrency-based Advance in any manner it deems fit and the foregoing
assumptions shall be utilized only for the purpose of the calculation of amounts
payable under this paragraph. Upon the written request of Company, Agent and
Banks shall deliver to Company a certificate setting forth the basis for
determining such losses, costs and expenses, which certificate shall be
conclusively presumed correct, absent manifest error.

         11.2 Agent's Eurocurrency Lending Office. For any Advance to which the
Eurocurrency-based Rate is applicable, if Agent shall designate a Eurocurrency
Lending Office which maintains books separate from those of the rest of Agent,
Agent shall have the option of maintaining and carrying the relevant Advance on
the books of such Eurocurrency Lending Office.

         11.3 Circumstances Affecting Eurocurrency-based Rate Availability. If
with respect to any Interest Period, Agent or the Banks (after consultation with
Agent) shall determine that, by reason of circumstances affecting the interbank
markets generally, deposits in eurodollars in the applicable amounts are not
being offered to the Agent for such Interest Period, then Agent shall forthwith
give notice thereof to the Company. Thereafter, until Agent notifies Company
that such circumstances no longer exist, the obligation of the Banks to make
Eurocurrency-based Advances, and the right of Company to convert an Advance to
or refund an Advance as a Eurocurrency-based Advance shall be suspended, and the
Company shall repay in full (or cause to be repaid in full) the then outstanding
principal amount of each such Eurocurrency-based Advance covered hereby together
with accrued interest thereon, any amounts payable (but not yet paid) under
Section 11.1, hereof, and all other amounts payable hereunder on the last day
of the then current Interest Period applicable to such Advance. Upon the date
for repayment as aforesaid and unless Company notifies Agent to the contrary
within two (2) Business Days after receiving a notice from Agent pursuant to
this Section, such outstanding principal amount shall be converted to a
Prime-based Advance as of the last day of such Interest Period.

         11.4 Laws Affecting Eurocurrency-based Advance Availability. In the
event that any applicable law, rule or regulation (whether domestic or foreign)
now or hereafter in effect and whether or not currently applicable to any Bank
or the Agent or any interpretation or administration thereof by any governmental
authority charged with the interpretation or administration thereof, or
compliance by the Agent or any of the Banks (or any of their respective
Eurocurrency Lending Offices) with any request or directive (whether or not
having the force of law) of any such authority,




                                       56
<PAGE>   64
shall make it unlawful or impossible for any of the Banks (or any of their
respective Eurocurrency Lending Offices) to honor its obligations hereunder to
make or maintain any Advance with interest at the Eurocurrency-based Rate, such
Bank or the Agent shall forthwith give notice thereof to Company and the Agent.
Thereafter the Agent shall so notify Company and the right of Company to convert
an Advance or refund an Advance as a Eurocurrency-based Advance, shall be
suspended and thereafter Company may select as Applicable Interest Rates only
those which remain available and which are permitted to be selected hereunder,
and if any of the Banks may not lawfully continue to maintain an Advance to the
end of the then current Interest Period applicable thereto as a
Eurocurrency-based Advance, Company shall immediately prepay such Advance,
together with interest to the date of payment, and any amounts payable under
Sections 11.1 or 11.6 with respect to such prepayment and the applicable
Advance shall immediately be converted to a Prime-based Advance and the
Prime-based Rate shall be applicable thereto.

         11.5 Increased Cost of Eurocurrency-based Advances. In the event that
any change in applicable law, rule or regulation (whether domestic or foreign)
now or hereafter in effect and whether or not currently applicable to any Bank
or the Agent or any interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Agent or any of the Banks (or any of
their respective Eurocurrency Lending Offices) with any request or directive
(whether or not having the force of law) made by any such authority, central
bank or comparable agency after the date hereof:

              (a) shall subject the Agent or any of the Banks (or any of their
         respective Eurocurrency Lending Offices) to any tax, duty or other
         charge with respect to any Advance or any Note or shall change the
         basis of taxation of payments to the Agent or any of the Banks (or any
         of their respective Eurocurrency Lending Offices) of the principal of
         or interest on any Advance or any Note or any other amounts due under
         this Agreement in respect thereof (except for changes in the rate of
         tax on the overall net income or revenues of the Agent or of any of the
         Banks (or any of their respective Eurocurrency Lending Offices) imposed
         by the United States of America or the jurisdiction in which such
         Bank's principal executive office is located); or

              (b) shall impose, modify or deem applicable any reserve
         (including, without limitation, any imposed by the Board of Governors
         of the Federal Reserve System), special deposit or similar requirement
         against assets of, deposits with or for the account of, or credit
         extended by the Agent or any of the Banks (or any of their respective
         Eurocurrency Lending Offices) or shall impose on the Agent or any of
         the Banks (or any of their respective Eurocurrency Lending Offices) or
         the interbank markets any other condition affecting any Advance or any
         of the Notes;

and the result of any of the foregoing is to increase the costs to the Agent or
any of the Banks of making, funding or maintaining any part of the Indebtedness
hereunder as a Eurocurrency-based Advance or to reduce the amount of any sum
received or receivable by the Agent or any of the Banks under this Agreement or
under the Notes in respect of a Eurocurrency-based Advance then Agent





                                       57
<PAGE>   65

or such Bank, as the case may be, shall promptly notify the Company of such fact
and demand compensation therefor and, within fifteen (15) days after such
notice, Company agrees to pay to Agent or such Bank such additional amount or
amounts as will compensate Agent or such Bank or Banks for such increased cost
or reduction. A certificate of Agent or such Bank setting forth the basis for
determining such additional amount or amounts necessary to compensate such Bank
or Banks shall accompany such demand for payment and shall be conclusively
presumed to be correct save for manifest error.

         For purposes of this Section, a change in law, rule, regulation,
interpretation, administration, request or directive shall include, without
limitation, any change made or which becomes effective on the basis of a law,
rule, regulation, interpretation, administration, request or directive presently
in force, the effective date of which change is delayed by the terms of such
law, rule, regulation, interpretation, administration, request or directive.

         11.6 Indemnity. The Company will indemnify Agent and each of the Banks
against any loss or expense which may arise or be attributable to the Agent's
and each Bank's obtaining, liquidating or employing deposits or other funds
acquired to effect, fund or maintain the Advances (a) as a consequence of any
failure by the Company to make any payment when due of any amount due hereunder
in connection with a Eurocurrency-based Advance, (b) due to any failure of the
Company to borrow on a date specified therefor in a Request for Revolving Credit
Advance or (c) due to any payment or prepayment of any Eurocurrency-based
Advance on a date other than the last day of the Interest Period for such
Advance, whether required by another provision of this Agreement or otherwise.
The Agent's and each Bank's (as applicable) calculations of any such loss or
expense shall be furnished to the Company and shall be conclusively presumed
correct, absent manifest error.

         11.7 Other Increased Costs. In the event that after the date hereof the
adoption of or any change in any applicable law, treaty, rule or regulation
(whether domestic or foreign) now or hereafter in effect and whether or not
presently applicable to any Bank or Agent, or any interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof, or compliance by any Bank or Agent
with any guideline, request or directive of any such authority (whether or not
having the force of law), including any risk based capital guidelines, affects
or would affect the amount of capital required or expected to be maintained by
such Bank or Agent (or any corporation controlling such Bank or Agent) and such
Bank or Agent, as the case may be, determines that the amount of such capital is
increased by or based upon the existence of such Bank's or Agent's obligations
or Advances hereunder and such increase has the effect of reducing the rate of
return on such Bank's or Agent's (or such controlling corporation's) capital as
a consequence of such obligations or Advances hereunder to a level below that
which such Bank or Agent (or such controlling corporation) could have achieved
but for such circumstances (taking into consideration its policies with respect
to capital adequacy) by an amount deemed by such Bank or Agent to be material
(collectively, "Increased Costs"), then Agent or such Bank shall notify the
Company, and thereafter the Company shall pay to such Bank or Agent, as the case
may be, from time to time, upon request by such Bank or Agent, additional
amounts sufficient to compensate such




                                       58
<PAGE>   66




Bank or Agent (or such controlling corporation) for any increase in the amount
of capital and reduced rate of return which such Bank or Agent reasonably
determines to be allocable to the existence of such Bank's or Agent's
obligations or Advances hereunder. A statement as to the amount of such
compensation, prepared in good faith and in reasonable detail by such Bank or
Agent, as the case may be, shall be submitted by such Bank or by Agent to the
Company, reasonably promptly after becoming aware of any event described in this
Section 11.7 and shall be conclusive, absent manifest error in computation.

         11.8 Substitution of Banks. If (i) the obligation of any Bank to make
Eurocurrency-based Advances has been suspended pursuant to Section 11.3 or
Section 11.4 or (ii) any Bank has demanded compensation under Section 11.5 (in
each case, an "Affected Lender"), Company shall have the right, with the
assistance of the Agent, to seek a substitute lender or lenders (which may be
one or more of the Banks (the "Purchasing Lender" or "Purchasing Lenders") to
purchase the Notes and assume the commitment (including without limitation its
participations in Letters of Credit) under this Agreement of such Affected
Lender. The Affected Lender shall be obligated to sell its Notes and assign its
commitment to such Purchasing Lender or Purchasing Lenders within fifteen days
after receiving notice from Company requiring it to do so, at an aggregate price
equal to the outstanding principal amount thereof plus unpaid interest accrued
thereon up to but excluding the date of the sale. In connection with any such
sale, and as a condition thereof, Company shall pay to the Affected Lender all
fees accrued for its account hereunder to but excluding the date of such sale,
plus, if demanded by the Affected Lender at least two Business Days prior to
such sale, (i) the amount of any compensation which would be due to the Affected
Lender under Section 11.1 if Company has prepaid the outstanding
Eurocurrency-based Advances of the Affected Lender on the date of such sale and
(ii) any additional compensation accrued for its account under Section 11.5 to
but excluding said date. Upon such sale, the Purchasing Lender or Purchasing
Lenders shall assume the Affected Lender's commitment and the Affected Lender
shall be released from its obligations hereunder to a corresponding extent. If
any Purchasing Lender is not already one of the Banks, the Affected Lender, as
assignor, such Purchasing Lender, as assignee, Company and the Agent shall enter
into an Assignment Agreement pursuant to Section 13.8 hereof, whereupon such
Purchasing Lender shall be a Bank party to this Agreement, shall be deemed to be
an assignee hereunder and shall have all the rights and obligations of a Bank
with a Percentage equal to its ratable share of the Revolving Credit Aggregate
Commitment of the Affected Lender. In connection with any assignment pursuant to
this Section 11.8, the Purchasing Lender shall pay to the Agent the
administrative fee for processing such assignment referred to in Section 13.8.
Upon the consummation of any sale pursuant to this Section 11.8, the Affected
Lender, the Agent and Company shall make appropriate arrangements so that, if
required, each Purchasing Lender receives a new Notes, as applicable.

12.      AGENT

         12.1 Appointment of Agent. Each Bank and the holder of each Note
irrevocably appoints and authorizes the Agent to act on behalf of such Bank or
holder under this Agreement and the other Loan Documents and to exercise such
powers hereunder and thereunder as are specifically delegated to Agent by the
terms hereof and thereof, together with such powers as may be reasonably
incidental



                                       59
<PAGE>   67




thereto, including without limitation the power to execute or authorize the
execution of financing or similar statements or notices, and other documents. In
performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Banks and does not assume and shall not be deemed to have
assumed any obligation towards or relationship of agency or trust with or for
Company. Each Bank agrees (which agreement shall survive any termination of this
Agreement) to reimburse Agent for all reasonable out-of-pocket expenses
(including house and outside attorneys' fees and disbursements) incurred by
Agent hereunder or in connection herewith or with an Event of Default or in
enforcing the obligations of Company under this Agreement or the other Loan
Documents or any other instrument executed pursuant hereto, and for which Agent
is not reimbursed by Company, pro rata according to such Bank's Percentage, but
excluding any such expense resulting from Agent's gross negligence or wilful
misconduct. Agent shall not be required to take any action under the Loan
Documents, or to prosecute or defend any suit in respect of the Loan Documents,
unless indemnified to its satisfaction by the Banks against loss, costs,
liability and expense (excluding liability resulting from its gross negligence
or wilful misconduct). If any indemnity furnished to Agent shall become
impaired, it may call for additional indemnity and cease to do the acts
indemnified against until such additional indemnity is given.

         12.2 Deposit Account with Age. Company hereby authorizes Agent, in
Agent's sole discretion, to charge its general deposit account(s), if any,
maintained with Agent for the amount of any principal, interest, or other
amounts or costs due under this Agreement when the same become due and payable
under the terms of this Agreement or the Notes.

         12.3 Scope of Agent's Duties. The Agent shall have no duties or
responsibilities except those expressly set forth herein, and shall not, by
reason of this Agreement or otherwise, have a fiduciary relationship with any
Bank (and no implied covenants or other obligations shall be read into this
Agreement against the Agent). None of Agent, its Affiliates nor any of their
respective directors, officers, employees or agents shall be liable to any Bank
for any action taken or omitted to be taken by it or them under this Agreement
or any document executed pursuant hereto, or in connection herewith or therewith
with the consent or at the request of the Majority Banks (or all of the Banks
for those acts requiring consent of all of the Banks) (except for its or their
own wilful misconduct or gross negligence), nor be responsible for or have any
duties to ascertain, inquire into or verify (a) any recitals or warranties made
by the Company, or any Subsidiary or Affiliate of the Company, or any officer
thereof contained herein or therein, (b) the effectiveness, enforceability,
validity or due execution of this Agreement or any document executed pursuant
hereto or any security thereunder, (c) the performance by Company of its
obligations hereunder or thereunder, or (d) the satisfaction of any condition
hereunder or thereunder, including without limitation the making of any Advance
or the issuance of any Letter of Credit. Agent and its Affiliates shall be
entitled to rely upon any certificate, notice, document or other communication
(including any cable, telegraph, telex, facsimile transmission or oral
communication) believed by it to be genuine and correct and to have been sent or
given by or on behalf of a proper person. Agent may treat the payee of any Note
as the holder thereof. Agent may employ agents and may consult with legal
counsel (who may be counsel for Company), independent public accountants and
other experts selected by it and shall not be liable to the Banks (except as to
money or property received by them or their authorized agents),



                                       60
<PAGE>   68

for the negligence or misconduct of any such agent selected by it with
reasonable care or for any action taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts.

          12.4 Successor Agent. Agent may resign as such at any time upon at
least 30 days prior notice to Company and all Banks. If Agent at any time shall
resign or if the office of Agent shall become vacant for any other reason,
Majority Banks shall, by written instrument, appoint successor agent(s)
satisfactory to such Majority Banks, and, so long as no Default or Event of
Default has occurred and is continuing, to Company. Such successor agent shall
thereupon become the Agent hereunder, as applicable, and shall be entitled to
receive from the prior Agent such documents of transfer and assignment as such
successor Agent may reasonably request. Any such successor Agent shall be a
commercial bank organized under the laws of the United States or any state
thereof and shall have a combined capital and surplus of at least $500,000,000.
If a successor is not so appointed or does not accept such appointment before
the resigning Agent's resignation becomes effective, the resigning Agent may
appoint a temporary successor to act until such appointment by the Majority
Banks is made and accepted or if no such temporary successor is appointed as
provided above by the resigning Agent, the Majority Banks shall thereafter
perform all of the duties of the resigning Agent hereunder until such
appointment by the Majority Banks is made and accepted. Such successor Agent
shall succeed to all of the rights and obligations of the resigning Agent as if
originally named. The resigning Agent shall duly assign, transfer and deliver to
such successor Agent all moneys at the time held by the resigning Agent
hereunder after deducting therefrom its expenses for which it is entitled to be
reimbursed. Upon such succession of any such successor Agent, the resigning
agent shall be discharged from its duties and obligations hereunder, except for
its gross negligence or wilful misconduct arising prior to its resignation
hereunder, and the provisions of this Article 13 shall continue in effect for
the benefit of the resigning Agent in respect of any actions taken or omitted to
be taken by it while it was acting as Agent.

          12.5 Agent in its Individual Capacity. Comerica Bank, its Affiliates
and their respective successors and assigns, shall have the same rights and
powers hereunder as any other Bank and may exercise or refrain from exercising
the same as though Comerica Bank were not the Agent. Comerica Bank and its
Affiliates may (without having to account therefor to any Bank) accept deposits
from, lend money to, and generally engage in any kind of banking, trust,
financial advisory or other business with Company (or its Subsidiaries) as if
Comerica Bank were not acting as Agent hereunder, and may accept fees and other
consideration therefor without having to account for the same to the Banks.

          12.6 Credit Decisions. Each Bank acknowledges that it has,
independently of Agent and each other Bank and based on the financial statements
of Company and such other documents, information and investigations as it has
deemed appropriate, made its own credit decision to extend credit hereunder from
time to time. Each Bank also acknowledges that it will, independently of Agent
and each other Bank and based on such other documents, information and
investigations as it shall deem appropriate at any time, continue to make its
own credit decisions as to exercising or



                                       61
<PAGE>   69

not exercising from time to time any rights and privileges available to it under
this Agreement or any document executed pursuant hereto.

         12.7 Agent's Fees. Company shall pay to Agent the annual agency fee and
such other fees and charges in the amounts and at the times set forth in the
letter agreement between Company and Agent dated July 20, 1998, as such letter
may be amended or restated with the Company's prior written consent from time to
time. The Agent's Fees described in this Section 12.7 shall not be refundable
under any circumstances.

         12.8 Authority of Agent to Enforce Notes and This Agreement. Each Bank,
subject to the terms and conditions of this Agreement, authorizes the Agent with
full power and authority as attorney-in-fact to institute and maintain actions,
suits or proceedings for the collection and enforcement of the Notes and to file
such proofs of debt or other documents as may be necessary to have the claims of
the Banks allowed in any proceeding relative to Company, or any of its
Subsidiaries, or their respective creditors or affecting their respective
properties, and to take such other actions which Agent considers to be necessary
or desirable for the protection, collection and enforcement of the Notes, this
Agreement or the other Loan Documents.

         12.9 Indemnification. The Banks agree to indemnify the Agent and its
Affiliates (to the extent not reimbursed by Company, but without limiting any
obligation of Company to make such reimbursement), ratably according to their
respective Percentages, from and against any and all claims, damages, losses,
liabilities, costs or expenses of any kind or nature whatsoever (including,
without limitation, fees and disbursements of counsel) which may be imposed on,
incurred by, or asserted against the Agent and its Affiliates in any way
relating to or arising out of this Agreement, any of the other Loan Documents or
the transactions contemplated hereby or any action taken or omitted by the Agent
and its Affiliates under this Agreement or any of the Loan Documents; provided,
however, that no Bank shall be liable for any portion of such claims, damages,
losses, liabilities, costs or expenses resulting from the Agent's or its
Affiliates's gross negligence or willful misconduct. Without limitation of the
foregoing, each Bank agrees to reimburse the Agent and its Affiliates promptly
upon demand for its ratable share of any out-of-pocket expenses (including,
without limitation, fees and expenses of counsel) incurred by the Agent and its
Affiliates in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement or any of the other Loan
Documents, to the extent that the Agent and its Affiliates is not reimbursed for
such expenses by Company, but without limiting the obligation of Company to make
such reimbursement. Each Bank agrees to reimburse the Agent and its Affiliates
promptly upon demand for its ratable share of any amounts owing to the Agent and
its Affiliates by the Banks pursuant to this Section, provided that, if the
Agent or its Affiliates is subsequently reimbursed by the Company for such
amounts, it shall refund to the Banks on a pro rata basis the amount of any
excess reimbursement. If the indemnity furnished to the Agent and its Affiliates
under this Section shall, in the judgment of the Agent, be insufficient or
become impaired, the Agent may call for additional indemnity from the Banks and
cease, or not commence, to take any action until such additional indemnity is
furnished.

       12.10 Knowledge of Default. It is expressly understood and agreed that
the Agent shall be entitled to assume that no Event of Default has occurred and
is continuing, unless the officers of the Agent immediately responsible for
matters concerning this Agreement shall have been notified in a writing
specifying such Event of Default and stating that such notice is a "notice of
default" by a Bank or by Company. Upon receiving such a notice, the Agent shall
promptly notify each Bank of such Event of Default and provide each Bank with a
copy of such notice and, shall endeavor to provide such notice to the Banks
within three (3) Business Days (but without any liability whatsoever in the

request, or to take any other action on behalf of the Banks (including without
limitation the exercise of any right or remedy hereunder or under the other Loan
Documents), the Agent shall be required to give such approval or consent, or to
make such request or to take such other action only when so requested in writing
by the Majority Banks or the Banks, as applicable hereunder. Action that may be
taken by Majority Banks or all of the Banks, as the case may be (as provided for
hereunder) may be taken (i) pursuant to a vote at a meeting (which may be held
by telephone conference call) as to which all of the Banks have been given
reasonable advance notice, or (ii) pursuant to the written consent of the
requisite Percentages of the Banks as required hereunder, provided that all of
the Banks are given reasonable advance notice of the requests for such consent.

       12.12 Enforcement Actions by the Agent. Except as otherwise expressly
provided under this Agreement or in any of the other Loan Documents and subject
to the terms hereof, Agent will take such action, assert such rights and pursue
such remedies under this Agreement and the other Loan Documents as the Majority
Banks or all of the Banks, as the case may be (as provided for hereunder), shall
direct; provided, however, that the Agent shall not be required to act or omit
to act if, in the judgment of the Agent, such action or omission may expose the
Agent to personal liability or is contrary to this Agreement, any of the Loan
Documents or applicable law. Except as expressly provided above or elsewhere in
this Agreement or the other Loan Documents, no Bank (other than the Agent,
acting in its capacity as agent) shall be entitled to take any enforcement
action of any kind under any of the Loan Documents.

of Company and the Banks and their respective successors and assigns,

         (b) The foregoing shall not authorize any assignment by Company, of its
rights or duties hereunder, and no such assignment shall be made (or effective)
without the prior written approval of the Banks.

         (c) The Company and Agent acknowledge that each of the Banks may at any
time and from time to time, subject to the terms and conditions hereof, assign
or grant participations in such Bank's rights and obligations hereunder and
under the other Loan Documents to any commercial bank, savings and loan
association, insurance company, pension fund, mutual fund, loan or debt

                                       66
<PAGE>   74

fund, commercial finance company or other similar financial institution, the
identity of which institution is approved by Company and Agent, such approval
not to be unreasonably withheld or delayed; provided, however, that (i) the
approval of Company shall not be required upon the occurrence and during the
continuance of a Default or Event of Default, and (ii) the approval of Company
and Agent shall not be required for any such sale, transfer, assignment or
participation to the Affiliate of an assigning Bank, any other Bank or any
Federal Reserve Bank. The Company authorizes each Bank to disclose to any
prospective assignee or participant, once approved by Company and Agent, any and
all financial information in such Bank's possession concerning the Company which
has been delivered to such Bank pursuant to this Agreement; provided that each
such prospective participant shall execute a confidentiality agreement
consistent with the terms of Section 13.12 hereof

         (d) Each assignment by a Bank of any portion of its rights and
obligations hereunder and under the other Loan Documents shall be made pursuant
to an Assignment Agreement substantially (as determined by Agent) in the form
attached hereto as Exhibit E (with appropriate insertions acceptable to Agent)
and shall be subject to the terms and conditions hereof, and to the following
restrictions:

            (i)         each assignment shall cover all of the Notes issued by
                        Company hereunder to the assigning Bank (and not any
                        particular note or notes), and shall be for a fixed and
                        not varying percentage thereof, with the same percentage
                        applicable to each such Note;

            (ii)        each assignment shall be in a minimum amount of the
                        lesser of (X) Five Million Dollars ($5,000,000) and (Y)
                        the entire remaining amount of assigning Bank's interest
                        in the Revolving Credit (and participations in any
                        outstanding Letters of Credit);

            (iii)       no assignment shall be effective unless Agent has
                        received from the assignee (or from the assigning Bank)
                        an assignment fee of $3,500 for each such assignment.

In connection with any assignment, Company and Agent shall be entitled to
continue to deal solely and directly with the assigning Bank in connection with
the interest so assigned until (x) the Agent shall have received a notice of
assignment duly executed by the assigning Bank and an Assignment Agreement (with
respect thereto) duly executed by the assigning Bank and each assignee; and (y)
the assigning Bank shall have delivered to the Agent the original of each Note
held by the assigning Bank under this Agreement. From and after the date on
which the Agent shall notify Company and the assigning Bank that the foregoing
conditions shall have been satisfied and all consents (if any) required shall
have been given, the assignee thereunder shall be deemed to be a party to this
Agreement. To the extent that rights and obligations hereunder shall have been
assigned to such assignee as provided in such notice of assignment (and
Assignment Agreement), such assignee shall have the rights and obligations of a
Bank under this Agreement and the other Loan Documents




                                       67
<PAGE>   75

(including without limitation the right to receive fees payable hereunder in
respect of the period following such assignment). In addition, the assigning
Bank, to the extent that rights and obligations hereunder shall have been
assigned by it as provided in such notice of assignment (and Assignment
Agreement), but not otherwise, shall relinquish its rights and be released from
its obligations under this Agreement and the other Loan Documents.

Within five (5) Business Days following Company's receipt of notice from the
Agent that Agent has accepted and executed a notice of assignment and the duly
executed Assignment Agreement, Company shall, to the extent applicable, execute
and deliver to the Agent in exchange for any surrendered Note, new Note(s)
payable to the order of the assignee in an amount equal to the amount assigned
to it pursuant to such notice of assignment (and Assignment Agreement), and with
respect to the portion of the Indebtedness retained by the assigning Bank, to
the extent applicable, new Note(s) payable to the order of the assigning Bank in
an amount equal to the amount retained by such Bank hereunder shall be executed
and delivered by the Company. Agent, the Banks and the Company acknowledge and
agree that any such new Note(s) shall be given in renewal and replacement of the
surrendered Notes and shall not effect or constitute a novation or discharge of
the Indebtedness evidenced by any surrendered Note, and each such new Note may
contain a provision confirming such agreement. In addition, promptly following
receipt of such Notes, Agent shall prepare and distribute to Company and each of
the Banks a revised Schedule 1.2 to this Agreement setting forth the applicable
new Percentages of the Banks (including the assignee Bank), taking into account
such assignment.

         (e) Each Bank agrees that any participation agreement permitted
hereunder shall comply with all applicable laws and shall be subject to the
following restrictions (which shall be set forth in the applicable Participation
Agreement):

            (i)         such Bank shall remain the holder of its Notes
                        hereunder, notwithstanding any such participation;

            (ii)        except as expressly set forth in this Section 13.8(e)
                        with respect to rights of setoff and the benefits of
                        Section 11 hereof, a participant shall have no direct
                        rights or remedies hereunder;

            (iii)       a participant shall not reassign or transfer, or grant
                        any sub-participations in its participation interest
                        hereunder or any part thereof; and

            (iv)        such Bank shall retain the sole right and responsibility
                        to enforce the obligations of the Company relating to
                        the Notes and the other Loan Documents, including,
                        without limitation, the right to proceed against any
                        Guaranties, or cause Agent to do so (subject to the
                        terms and conditions hereof), and the right to approve
                        any amendment, modification or waiver of any provision
                        of this Agreement without the consent of the
                        participant, except for those matters covered by Section
                        13.11 (a) through (e) and (h) hereof




                                       68
<PAGE>   76




                        (provided that a participant may exercise approval
                        rights over such matters only on an indirect basis,
                        acting through such Bank, and Company, Agent and the
                        other Banks may continue to deal directly with such Bank
                        in connection with such Bank's rights and duties
                        hereunder).

Company agrees that each participant shall be deemed to have the right of setoff
under Section 9.6 hereof in respect of its participation interest in amounts
owing under this Agreement and the other Loan Documents to the same extent as if
the Indebtedness were owing directly to it as a Bank under this Agreement, shall
be subject to the pro rata recovery provisions of Section 10.3 hereof and shall
be entitled to the benefits of Section 11 hereof. The amount, terms and
conditions of any participation shall be as set forth in the participation
agreement between the issuing Bank and the Person purchasing such participation,
and none of the Company, the Agent and the other Banks shall have any
responsibility or obligation with respect thereto, or to any Person to whom any
such participation may be issued. No such participation shall relieve any
issuing Bank of any of its obligations under this Agreement or any of the other
Loan Documents, and all actions hereunder shall be conducted as if no such
participation had been granted.

         (f) Nothing in this Agreement, the Notes or the other Loan Documents,
expressed or implied, is intended to or shall confer on any Person other than
the respective parties hereto and thereto and their successors and assignees and
participants permitted hereunder and thereunder any benefit or any legal or
equitable right, remedy or other claim under this Agreement, the Notes or the
other Loan Documents.

       13.9 Indulgence. No delay or failure of Agent and the Banks in exercising
any right, power or privilege hereunder shall affect such right, power or
privilege nor shall any single or partial exercise thereof preclude any further
exercise thereof, nor the exercise of any other right, power or privilege. The
rights of Agent and the Banks hereunder are cumulative and are not exclusive of
any rights or remedies which Agent and the Banks would otherwise have.

       13.10 Counterparts. This Agreement may be executed in several
counterparts, and each executed copy shall constitute an original instrument,
but such counterparts shall together constitute but one and the same instrument.

       13.11 Amendment and Waiver. No amendment or waiver of any provision of
this Agreement or any other Loan Document, nor consent to any departure by
Company or any Subsidiary therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Majority Banks (or by the Agent at
the written request of the Majority Banks) or, if this Agreement expressly so
requires with respect to the subject matter thereof, by all Banks (and, with
respect to any amendments to this Agreement or the other Loan Documents, by
Company or the Subsidiaries which are signatories thereto), and then such waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no amendment, waiver or consent
shall, unless in writing and signed by all the Banks, do any of the following:
(a) increase any Bank's commitments hereunder, (b) reduce the principal of, or
interest



                                       69
<PAGE>   77

on, the Notes or any Fees or other amounts payable hereunder, (c) postpone any
date fixed for any payment of principal of, or interest on, the Notes or any
Fees or other amounts payable hereunder, (d) waive any Event of Default
specified in Sections 9.1(a) or (b) hereof, (e) release any guaranty or
similar undertaking provided by any Person except as shall be otherwise
expressly permitted in this Agreement or any other Loan Document; (f) terminate
or modify any indemnity provided to the Banks hereunder or under the other Loan
Documents, except as shall be otherwise expressly provided in this Agreement or
any other Loan Document, (g) take any action which requires the approval or
consent of all Banks pursuant to the terms of this Agreement or any other Loan
Document, (h) change the aggregate unpaid principal amount of the Notes which
shall be required for the Banks or any of them to take any action under this
Agreement or any Loan Document or (i) change the definition of "Majority Banks"
or this Section 12.11; provided further, however, that no amendment, waiver, or
consent shall, unless in writing and signed by the Agent in addition to all the
Banks, affect the rights or duties of the Agent under this Agreement or any
other Loan Document. All references in this Agreement to "Banks" or "the Banks"
shall refer to all Banks, unless expressly stated to refer to Majority Banks.

       13.12 Confidentiality. Each Bank agrees that it will not disclose without
the prior consent of Company (other than to its employees, its Subsidiaries,
another Bank or to its auditors or counsel) any information with respect to
Company, which is furnished pursuant to this Agreement or any of the other Loan
Documents and will not use such information for its financial benefit outside of
the corporate lending relationship; provided that any Bank may disclose any such
information (a) as has become generally available to the public or has been
lawfully obtained by such Bank from any third party under no duty of
confidentiality to Company, (b) as may be required or appropriate in any report,
statement or testimony submitted to, or in respect to any inquiry, by, any
municipal, state or federal regulatory body having or claiming to have
jurisdiction over such Bank, including the Board of Governors of the Federal
Reserve System of the United States, the Office of the Comptroller of the
Currency or the Federal Deposit Insurance Corporation or similar organizations
(whether in the United States or elsewhere) or their successors, (c) as may be
required or appropriate in respect to any summons or subpoena or in connection
with any litigation, (d) in order to comply with any law, order, regulation or
ruling applicable to such Bank, and (e) to any permitted transferee or assignee
or to any approved participant of, or with respect to, the Notes, as aforesaid.

       13.13 Withholding Taxes. If any Bank is not incorporated under the laws
of the United States or a state thereof, such Bank shall promptly deliver to the
Agent two executed copies of (i) Internal Revenue Service Form 1001 specifying
the applicable tax treaty between the United States and the jurisdiction of such
Bank's domicile which provides for the exemption from withholding on interest
payments to such Bank, (ii) Internal Revenue Service Form 4224 evidencing that
the income to be received by such Bank hereunder is effectively connected with
the conduct of a trade or business in the United States or (iii) other evidence
satisfactory to the Agent and Company that such Bank is exempt from United
States income tax withholding with respect to such income. Such Bank shall amend
or supplement any such form or evidence as required to insure that it is
accurate, complete and non-misleading at all times. Promptly upon notice from
the Agent of any determination by the Internal Revenue Service that any payments
previously made to such Bank hereunder were subject to United States income tax
withholding when made, such Bank shall pay to the Agent the



                                       70
<PAGE>   78

excess of the aggregate amount required to be withheld from such payments over
the aggregate amount actually withheld by the Agent.

       13.14 Taxes and Fees. Should any tax (other than as a result of a Bank's
failure to comply with Section 14.13 or a tax based upon the net income or
capitalization of any Bank or the Agent by any jurisdiction where a Bank or
Agent is located), recording or filing fee become payable in respect of this
Agreement or any of the other Loan Documents or any amendment, modification or
supplement hereof or thereof, the Company agrees to pay the same, together with
any interest or penalties thereon arising from the Company's act or omission,
and agrees to hold the Agent and the Banks harmless with respect thereto.
Notwithstanding the foregoing, nothing contained in this Section 13.14 shall

                                    GUARANTY

     This GUARANTY is made as of the 24th day of July, 1998 by each of the
undersigned guarantors (the "Guarantors"), to Comerica Bank, as Agent ("Agent")
for and on behalf of the Banks (as defined below).

                                    RECITALS

     A. Pursuant to that certain Credit Agreement dated as of July 24, 1998 (as
amended or otherwise modified from time to time, the "Credit Agreement") by and
among Meadowbrook Insurance Group, Inc., a Michigan corporation (the "Company"),
Agent and the banks which are named in and signatories to the Credit Agreement
("Banks"), the Banks have agreed to extend credit to Company on the terms set
forth in the Credit Agreement, with such credit consisting of (i) the Revolving
Credit in an aggregate amount, subject to the terms of the Credit Agreement, of
up to Fifty Million Dollars ($50,000,000) at any one time outstanding, to be
evidenced by the Revolving Credit Notes made or to be made by the Company to the
Banks ("Revolving Credit Notes"); and (ii) a facility for the issuance of
letter(s) of credit ("Letter(s) of Credit") for the account of the Company,
individually, or jointly and severally with other Account Parties pursuant to
Section 3 of the Credit Agreement, subject to specified availability thereunder.

     B. As a condition to entering into and performing their respective
obligations under the Credit Agreement, the Banks and the Agent have required
that the Guarantors provide to Agent, for and on behalf of the Banks, this
Guaranty.

     C. Each of the Guarantors desires to see the success of the Company and,
furthermore, shall receive direct and/or indirect benefits from extensions of
credit made or to be made pursuant to the Credit Agreement to the Company.

     D. The Agent is acting as Agent for the Banks pursuant to the terms of the

     NOW, THEREFORE, as a continuing inducement to the Agent and the Banks to
enter into and perform its obligations under the Credit Agreement, each of the
Guarantors has executed and delivered this guaranty ("Guaranty").

     1. Definitions. Unless otherwise provided herein, all capitalized terms
used in this Guaranty shall have the meanings specified in the Credit Agreement.
The term "Banks" as used herein shall include any successors or permitted
assigns of the Banks, in accordance with the Credit Agreement.

     2. Guaranty. Each of the Guarantors hereby guarantees to the Banks the
punctual payment to the Banks when due, whether by acceleration or otherwise, of
all amounts, including, without limitation, principal, interest (including
interest accruing on or after the filing of any petition in bankruptcy, or the
commencement of any insolvency, reorganization or like proceeding by such
Guarantor, whether or not a claim for post-filing or post-petition interest is
allowed in such a proceeding), and all other liabilities and obligations, direct
or indirect, absolute or contingent, due or to become due, now existing or
hereafter incurred, which may arise under, out of, or in connection with:

          (a)  any and all Revolving Credit Notes made or to be made to the
     order of the Banks (or any of them) by the Company, from time to time
     pursuant to the terms and conditions of the Credit Agreement;

          (b)  any and all Letter of Credit Agreements executed or to be
     executed by the Company or the other Account Parties and any of them, from
     time to time pursuant to the Credit Agreement, and any Letters of Credit
     issued or to be issued thereunder;

          (c)  any Interest Rate Protection Agreements;

          (d)  all other Indebtedness (as defined in the Credit Agreement) of
     the Company and/or any Account Party, under or in connection with the
     Credit Agreement or the other Loan Documents, whether such Indebtedness is
     now existing or hereafter arising; and

          (e)  all extensions, renewals and amendments of or to the Revolving
     Credit Notes (collectively, and any of such notes, the "Notes"), Letter of
     Credit Agreements, Letters of Credit, Interest Rate Protection Agreements,
     or such other Indebtedness, or any replacements or substitutions therefor;

whether on account of principal, interest, reimbursement obligations, fees,
indemnities, and reasonable costs and expenses (including without limitation,
all reasonable fees and disbursements of counsel to the Agent or any Bank) or
otherwise, and hereby agrees that if Company shall fail to pay any of such
amounts when and as the same shall be due and payable, or shall fail to perform
and discharge any covenant, representation or warranty in accordance with the
terms of the Notes, the Credit Agreement, the Letter of Credit Agreements, the
Letters of Credit or any of the other Loan Documents (subject, in each case, to
any applicable periods of grace or cure), each such Guarantor will forthwith pay
to the Agent, on behalf of the Banks, an amount equal to any such amount or
cause Company to perform and discharge any such covenant, representation or
warranty, as the case may be, and will pay any and all damages that may be
incurred or suffered in consequence thereof by Agent or any of the Banks and all
reasonable expenses, including reasonable attorneys' fees, that may be incurred
by Agent in enforcing such covenant, representation or warranty of Company, and
in enforcing the covenants and agreements of this Guaranty.

<PAGE>   96
                                                                                
     3. Unconditional Character of Guaranty. The obligations of each of the
Guarantors under this Guaranty, to the full extent of its guaranty of
Indebtedness hereunder, shall be absolute and unconditional, and shall be a
guaranty of payment and not of collection, irrespective of the validity,
regularity or enforceability of the Notes, the Credit Agreement, the Letter of
Credit Agreements, the Letters of Credit or any of the other Loan Documents, or
any provision thereof, the absence of any action to enforce the same, any waiver
or consent with respect to or any amendment of any provision thereof, the
recovery of any judgment against any Person or action to enforce the same, any
failure or delay in the enforcement of the obligations of Company under the
Notes, the Credit Agreement, the Letter of Credit Agreements, the Letters of
Credit or any of the other Loan Documents, or any setoff, counterclaim,
recoupment, limitation, defense or termination, whether with or without notice
to such Guarantor. Each of the Guarantors hereby waives diligence, demand for
payment, filing of claims with any court, any proceeding to enforce any
provision of the Notes executed by Company, or the Credit Agreement, the Letter
of Credit Agreements, the Letters of Credit or any of the other Loan Documents,
any right to require a proceeding first against Company, or against any other
guarantor or other party providing collateral, or to exhaust any security for
the performance of the obligations of Company, any protest, presentment, notice
or demand whatsoever, and such Guarantor hereby covenants that this Guaranty
shall not be terminated, discharged or released except, subject to Section 6.5
hereof, upon final payment in full (subject to no revocation or rescission) of
all amounts due and to become due from Company or any Account Party, as and to
the extent described above, and only to the extent of any such payment,
performance and discharge. Each of the Guarantors further covenants that no
security now or subsequently held by the Agent or the Banks for the payment of
the Indebtedness evidenced by the Notes made by Company, under the Credit
Agreement, or for the payment of any other Indebtedness of Company, to the Agent
or the Banks under the Credit Agreement, the Letter of Credit Agreements, the
Letters of Credit or the other Loan Documents, whether in the nature of a
security interest, pledge, lien, assignment, setoff, suretyship, guaranty,
indemnity, insurance or otherwise, and no act, omission or other conduct of
Agent or the Banks in respect of such security, shall affect in any manner
whatsoever the unconditional obligation of this Guaranty, and that the Agent and
each of the Banks, in their respective sole discretion and without notice to
Company, may release, exchange, enforce, apply the proceeds of and otherwise
deal with any such security without affecting in any manner the unconditional
obligation of this Guaranty.

     Without limiting the generality of the foregoing, such obligations, and
the rights of the Agent to enforce the same on behalf of the Banks, by
proceedings, whether by action at law, suit in equity or otherwise, shall not be
in any way affected by (i) any insolvency, bankruptcy, liquidation,
reorganization, readjustment, composition, dissolution, winding up or other
proceeding involving or affecting Company, or others, or (ii) any change in the
ownership of the capital stock of Company, or any other party providing
collateral for any indebtedness covered by this Guaranty, or any of their
respective Affiliates.

     Each of the Guarantors hereby waives to the fullest extent possible under
applicable law:

                                       3
<PAGE>   97
        (a) any defense based upon the doctrine of marshaling of assets or upon
an election of remedies by Agent or the Banks, including, without limitation, an
election to proceed by non-judicial rather than judicial foreclosure;

        (b) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;

        (c) any duty on the part of Agent or any of the Banks to disclose to 
such Guarantor any facts Agent or the Banks may now or hereafter know about the
Company, regardless of whether Agent or any Bank has reason to believe that any
such facts materially increase the risk beyond that which such Guarantor intends
to assume or has reason to believe that such facts are unknown to such Guarantor
or has a reasonable opportunity to communicate such facts to such Guarantor,
since such Guarantor acknowledges that it is fully responsible for being and
keeping informed of the financial condition of Company and of all circumstances
bearing on the risk of nonpayment of any Indebtedness hereby guaranteed;

        (d) any claim for reimbursement, contribution, exoneration, indemnity or
subrogation, or any other similar claim, which such guarantor may have or obtain
against the Company, by reason of the existence of this Guaranty, or by reason
of the payment by such Guarantor of any Indebtedness or the performance of this
Guaranty or of any other Loan Documents, until the Indebtedness has been repaid
and discharged in full and no commitment to extend any credit under the Credit
Agreement or any of the Loan Documents (whether optional or obligatory), or any
Letter of Credit, remains outstanding, and any amounts paid to such Guarantor on
account of any such claim at any time when the obligations of such Guarantor
under this Guaranty shall not have been fully and finally paid shall be held by
such Guarantor in trust for Agent and the Banks, segregated from other funds of
such Guarantor, and forthwith upon receipt by such Guarantor shall be turned
over to Agent in the exact form received by such Guarantor (duly endorsed to
Agent by such Guarantor, if required), to be applied to such Guarantor's
obligations under this Guaranty, whether matured or unmatured, in such order and
manner as Agent may determine; and

        (e) any other event or action (excluding compliance by such Guarantor 
with the provisions hereof) that would result in the discharge by operation of
law or otherwise of such Guarantor from the performance or observance of any
obligation, covenant or agreement contained in this Guaranty.

     The Agent and each of the Banks may deal with Company, and any security
held by them for the obligations of Company or any other Account Party (as
aforesaid), in the same manner and as freely as if this Guaranty did not exist
and the Agent shall be entitled, on behalf of Banks, without notice to the
Guarantors, among other things, to grant to the Company, such extension or
extensions of time to perform any act or acts as may seem advisable to such
Agent (on behalf of the Banks) at any time and from time to time, and to permit
the Company or any other Account Party to incur additional indebtedness to
Agent, the Banks, or any of them, without terminating, affecting or

                                       4
<PAGE>   98




impairing the validity or enforceability of this Guaranty or the obligations of
the Guarantors hereunder.

     The Agent may proceed, either in its own name (on behalf of the Banks) or
in the name of any of the Guarantors, or otherwise, to protect and enforce any
or all of its rights under this Guaranty by suit in equity, action at law or by
other appropriate proceedings, or to take any action authorized or permitted
under applicable law, and shall be entitled to require and enforce the
performance of all acts and things required to be performed hereunder by the
Guarantors. Each and every remedy of the Agent and of the Banks shall, to the
extent permitted by law, be cumulative and shall be in addition to any other
remedy given hereunder or now or hereafter existing at law or in equity.

     No waiver or release shall be deemed to have been made by the Agent or any
of the Banks of any of its rights hereunder unless the same shall be in writing
and signed by all of the Banks or on behalf of the Banks by the Agent, and any
such waiver shall be a waiver or release only with respect to the specific
matter involved and shall in no way impair the rights of the Agent or any of the
Banks or the obligations of the Guarantors under this Guaranty in any other
respect at any other time.

     At the option of the Agent, any of the Guarantors may be joined in any
action or proceeding commenced by the Agent against Company, or any of the other
parties providing collateral for any indebtedness covered by this Guaranty in
connection with or based upon the Notes made by Company, the Credit Agreement,
the Letter of Credit Agreements, the Letters of Credit or any of the other Loan
Documents or other Indebtedness, or any provision thereof, and recovery may be
had against any such Guarantor in such action or proceeding or in any
independent action or proceeding against such Guarantor, without any requirement
that the Agent or the Banks first assert, prosecute or exhaust any remedy or
claim against Company, and/or any of the other parties providing collateral for
any Indebtedness covered by this Guaranty, or any other Indebtedness.

     As a separate, additional and continuing obligation, each of the
Guarantors unconditionally and irrevocably undertakes and agrees with Agent
that, should the amounts referred to in Section 2 of this Guaranty not be
recoverable from such Guarantor in its capacity as a guarantor under this
Guaranty for any reason whatsoever (including, without limitation, by reason of
any provision of the Notes, the Credit Agreement, any Letter of Credit Agreement
or Letter of Credit, or any of the other Loan Documents being or becoming void,
unenforceable, or otherwise invalid under any applicable law) then,
notwithstanding any knowledge thereof by the Agent and the Banks or any of them
at any time, such Guarantor as sole, original and independent obligor, upon
demand by Agent, will make payment to Agent of all such amounts by way of a full
indemnity.

     4. Representations and Warranties. Each of the Guarantors (a) ratifies,
confirms and, by reference thereto (as fully as though such matters were
expressly set forth herein), represents and warrants with respect to itself
those matters set forth in Section 6 of the Credit Agreement, and (b) agrees not
to engage in any action or inaction, the result of which would cause a violation
of any term or condition of the Credit Agreement.

to its conflict of laws provisions), each of the Guarantors hereby consenting to
the jurisdiction of state and all federal courts sitting in such state.

          5.2 Severability. If any term or provision of this Guaranty, or the
application thereof to any circumstance, shall, to any extent, be invalid or
unenforceable, the remainder of this Guaranty, or the application of such term
or provision to circumstances other than those as to which it is held invalid or
unenforceable, as the case may be, shall not be affected thereby, and each term,
provision and obligation of this Guaranty shall be valid and enforceable to the
fullest extent permitted by law.

          5.3 Notice. All notices and other communications to be made or given
pursuant to this Guaranty shall be sufficient if made or given in conformity
with Section 13.6 of the Credit Agreement.

          5.4 Right of Offset. Each of the Guarantors acknowledges the rights of

Banks, or either or any of them to such Guarantor, whether represented by any
deposit of such Guarantor with the Agent or any of the Banks or otherwise.

          5.5 Release. Upon the satisfaction of the obligations of the
Guarantors hereunder, and when the Guarantors are not subject to any obligation
under the Credit Agreement or any of the other Loan Documents, the Agent shall
deliver to the Guarantors, upon written request therefor, a written release of
this Guaranty; provided however that the effectiveness of this Guaranty shall
continue or be reinstated, as the case may be, in the event that any payment
received or credit given by the Agent or the Banks, or any of them, is returned,
disgorged, rescinded or required to be recontributed to any party as an
avoidable preference, impermissible setoff, fraudulent conveyance, restoration
of capital or otherwise under any applicable state, federal or national law of
any jurisdiction, including without limitation laws pertaining to bankruptcy or
insolvency, and this Guaranty shall thereafter be enforceable against the
Guarantors as if such returned, disgorged, recontributed or rescinded payment or
credit had not been received or given by the Agent or the Banks, and whether or
not the Agent or any Bank relied upon such payment or credit or changed its
position as a consequence thereof.

of the Guarantors under this Guaranty shall be several and also joint, each with
all and also each with any one or more of the others, and may be enforced
against each severally, any two or more jointly, or some severally and some
jointly. Any one or more of the Guarantors may be released from its obligations
hereunder with or without consideration for such release and the obligations of
the other Guarantors hereunder shall be in no way affected thereby. Agent, on
behalf of Banks, may fail or elect not to prove a claim against any bankrupt or
insolvent Guarantor and thereafter, Agent and the Bank may, without notice to
any Guarantors, extend or renew any part or all of any indebtedness of any of
the Guarantors, and may permit any of the Guarantors to incur additional
indebtedness, without affecting in any manner the unconditional obligation of
the remaining Guarantors. Such action shall not affect any right of contribution
among the Guarantors.

          5.9 WAIVER OF JURY TRIAL. THE BANKS (BY ACCEPTING THE BENEFITS
HEREOF), THE AGENT (BY ACCEPTING THE BENEFITS HEREOF) AND EACH OF THE GUARANTORS
AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL,
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO
A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS GUARANTY OR
ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT,
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTION OF ANY OF THEM. NEITHER
THE BANKS, THE AGENT, NOR ANY OF THE GUARANTORS SHALL SEEK TO CONSOLIDATE, BY
COUNTERCLAIM OR OTHERWISE, ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED

WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.
THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR
RELINQUISHED BY THE BANKS AND THE AGENT OR THE GUARANTORS EXCEPT BY A WRITTEN
INSTRUMENT EXECUTED BY ALL OF THEM.

          5.10 Limitation under Applicable Insolvency Laws. Notwithstanding     
anything to the contrary contained herein, it is the intention of each of the
Guarantors, Agent and the Banks that the amount of each Guarantor's obligations
hereunder shall be in, but not in excess of, the maximum amount thereof not
subject to avoidance or recovery by operation of applicable law governing
bankruptcy, reorganization, arrangement, adjustment of debts, relief of debtors,
dissolution, insolvency, fraudulent transfers or conveyances or other similar
laws (collectively, "Applicable Insolvency Laws"). To that end, but only in the
event and to the extent that a Guarantor's obligations hereunder or any payment
made pursuant thereto would, but for the operation of the foregoing proviso, be
subject to avoidance or recovery under Applicable Insolvency Laws, the amount of
such Guarantor's obligations hereunder shall be limited to the largest amount
which, after effect thereto, would not, under Applicable Insolvency Laws, render
such Guarantor's respective obligations hereunder unenforceable or avoidable or
subject to recovery under Applicable Insolvency Laws. To the extent any payment
actually made hereunder exceeds the limitation contained in this Section 5.10,
then the amount of such excess shall, from and after the time of payment by the
Guarantors (or any of them), be reimbursed by the Banks upon demand by such
Guarantor. The foregoing proviso is intended solely to preserve the rights of
the Agent and the Banks hereunder against the Guarantors to the maximum extent
permitted by Applicable Insolvency Laws and neither Company nor any Guarantor
nor any other Person shall have any right or claim under this Section 5.10 that
would not otherwise be available under Applicable Insolvency Laws. To effectuate
the foregoing, the parties to this Agreement acknowledge and agree that the
provisions of this Section 5.10 only apply to Guarantors which are Domestic
Subsidiaries of the Company.
