                   and correct in all material respects as of and immediately
                   after the making of the Advance; and

          (v)      the execution of such Revolving Credit Advance will not
                   violate the material terms and conditions of any material
                   contract, agreement or other borrowing of Company or any of
                   its Subsidiaries.

         Agent, acting on behalf of the Banks, may, at its option, lend under
this Section 2 upon the telephone request of an authorized officer of Company
and, in the event Agent, acting on behalf of the Banks, makes any such Advance
upon a telephone request, the requesting officer shall, if so requested by
Agent, fax to Agent, on the same day as such telephone request, a Request for
Advance. Company hereby authorizes Agent to disburse Advances under this Section
2.3 pursuant to the telephone instructions of any person purporting to be a
person identified by name on a written list of persons authorized by the Company
to make Requests for Advance on behalf of the Company. Notwithstanding the
foregoing, the Company acknowledges that Company shall bear all risk of loss
resulting from disbursements made upon any telephone request. Each telephone
request for an Advance shall constitute a certification of the matters set forth
in the Request for Advance form as of the date of such requested Advance.

         2.4  Disbursement of Revolving Credit Advances.

              (a)  Upon receiving any Request for a Revolving Credit Advance
         from Company under Section 2.3 hereof, Agent shall promptly notify each
         Bank by wire, telecopy, telex or by telephone (confirmed by wire,
         telecopy or telex) of the amount of such Revolving Credit Advance to be
         made and the date such Advance is to be made by said Bank pursuant to
         its Percentage of the Revolving Credit Advance. Unless such Bank's
         commitment to make Revolving Credit Advances hereunder shall have been
         suspended or terminated in accordance with this Agreement, each Bank
         shall send the amount of its Percentage of the Advance in same day
         funds in Dollars to Agent at the office of Agent located at One Detroit
         Center, 500 Woodward Avenue, Detroit, Michigan 48226-3239 not later
         than 3:00 p.m. (Detroit time) on the date of such Advance.

              (b)  Subject to submission of a Request for Revolving Credit
         Advance delivered in accordance with Section 2.3 hereof by Company
         without exceptions noted in the compliance certification therein and to
         the other terms and conditions hereof, Agent shall make available to
         Company the aggregate of the amounts so received by it from the Banks
         under this Section 2.4, in like funds, not later than 4:00 p.m.
         (Detroit time) on the date of such Revolving Credit Advance by credit
         to an account of Company maintained with Agent or to such other account
         or third party as Company may reasonably direct.

              (c)  Unless Agent shall have been notified by any Bank prior to
         the date of any proposed Revolving Credit Advance that such Bank does
         not intend to make available to Agent such Bank's Percentage of the
         Revolving Credit Advance, Agent may assume that such Bank has made such
         amount available to Agent on such date, as aforesaid and may, in its
         sole discretion and without obligation to do so, in reliance upon such
         assumption, make available




                                       18
<PAGE>   28

         to Company a corresponding amount. Any such notice of intention not to
         make an Advance shall be subject to the provisions of Section 2.1 of
         this Agreement. If such 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 and such payment to Agent shall be without
         waiver of Company's claims, if any, against such Bank. 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

              (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,
1999 (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 one quarter of one percent (3%) 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



                                       19
<PAGE>   29

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.

         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,



                                       20
<PAGE>   30

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 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.

Each Letter of Credit Agreement submitted to Issuing Bank pursuant hereto shall
constitute the certification by the Company and the Account Party of the matters

or promptly following its delivery of any Letter of Credit, a true and complete

              (a)  A per annum Letter of Credit Fee with respect to the undrawn

         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

         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

         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,

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

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


                                       24
<PAGE>   34


         parties hereto, including without limitation the obligations of the
         Company or applicable Account Party under Section 3.6(a) hereof.

              (c)  Upon issuance by the Issuing Bank of each Letter of Credit
         hereunder and upon execution of this Agreement with respect to the
         Existing Letters of Credit, 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 hereunder, 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;


                                       25
<PAGE>   35

              (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 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
         any right, power or remedy conferred upon the Agent, the Issuing Bank,
         any other Bank or any such party under this Agreement, any of the Loan
         Documents or any of the Letter of Credit Documents, or any other acts
         or omissions on the part of the Agent, the Issuing Bank, any other Bank
         or any such party; or

              (f)  Absent gross negligence or willful misconduct on the part of
         the Issuing Bank or Banks, any other event or circumstance that would,
         in the absence of this Section 3.7, result in the release or discharge
         by operation of law or otherwise of Company or any Account Party from
         the performance or observance of any obligation, covenant or agreement
         contained in Section 3.6.

No setoff, counterclaim, reduction or diminution of any obligation or any
defense of any kind or nature which Company or any Account Party has or may have
against the beneficiary of any Letter of Credit shall be available hereunder to
Company or any Account Party against the Agent, the Issuing Bank or any other
Bank. Nothing contained in this Section 3.7 shall be deemed to prevent Company
or the Account Parties, after satisfaction in full of the absolute and
unconditional obligations of Company and the Account Parties hereunder, from
asserting in a separate action any claim, defense, set off or other right which
they (or any of them) may have against Agent, the Issuing Bank or any Bank.

         3.8  Risk Under Letters of Credit. (a) In the handling of Letters of
Credit and any security therefor, or any documents or instruments given in
connection therewith, and notwithstanding the granting of risk participation
hereunder, the Issuing Bank shall have the sole right to take or refrain from
taking any and all actions under or upon the Letters of Credit.

              (b)  Subject to other terms and conditions of this Agreement,
         Issuing Bank shall issue the Letters of Credit and shall hold the
         documents related thereto in its own name and shall make all
         collections thereunder and otherwise administer the Letters of Credit
         in accordance with Issuing Bank's regularly established practices and
         procedures and, Issuing Bank will have no further obligation with
         respect thereto. In the administration of Letters of Credit, Issuing
         Bank shall not be liable for any action taken or omitted on the advice
         of



                                       26
<PAGE>   36

         counsel, accountants, appraisers or other experts selected by Issuing
         Bank with due care and Issuing Bank may rely upon any notice,
         communication, certificate or other statement from Company, any Account
         Party, beneficiaries of Letters of Credit, or any other Person which
         Issuing Bank believes to be authentic. Issuing Bank, will, upon
         request, furnish the Banks with copies of Letter of Credit Agreements,
         Letters of Credit and documents related thereto.

              (c)  In connection with the issuance and administration of Letters
         of Credit and the assignments hereunder, Issuing Bank makes no
         representation and shall, subject to Section 3.7 hereof, have no
         responsibility with respect to (i) the obligations of Company or any
         Account Party or, the validity, sufficiency or enforceability of any
         document or instrument given in connection therewith, (ii) the
         financial condition of, any representations made by, or any act or
         omission of Company, the applicable Account Party or any other Person,
         or (iii) any failure or delay in exercising any rights or powers
         possessed by Issuing Bank in its capacity as issuer of Letters of
         Credit, in the absence of its gross negligence or willful misconduct.
         Each of the Banks expressly acknowledge that they have made and will
         continue to make their own evaluations of Company's creditworthiness
         without reliance on any representation of Issuing Bank or Issuing
         Bank's officers, agents and employees.

              (d)  If at any time Agent or the Issuing Bank shall recover any
         part of any unreimbursed amount for any draw or other demand for
         payment under a Letter of Credit, or any interest thereon, Agent or the
         Issuing Bank, as the case may be, shall receive same for the pro rata
         benefit of the Banks in accordance with their respective Percentage
         interests therein and shall promptly deliver to each Bank its share
         thereof, less such Bank's pro rata share of the costs of such recovery,
         including court costs and attorney's fees. If at any time any Bank
         shall receive from any source whatsoever any payment on any such
         unreimbursed amount or interest thereon in excess of such Bank's
         Percentage share of such payment, such Bank will promptly pay over such
         excess to Agent, for redistribution in accordance with this Agreement.

         3.9  Indemnification. (a) The Company and each Account Party hereby
indemnifies and agrees to hold harmless the Banks, the Issuing Bank and the
Agent, and their respective officers, directors, employees and agents, from and
against any and all claims, damages, losses, liabilities, costs or expenses of
any kind or nature whatsoever which the Banks, the Issuing Bank or the Agent or
any such Person may incur or which may be claimed against any of them by reason
of or in connection with any Letter of Credit, and none of the Issuing Bank, any
Bank or the Agent or any of their respective officers, directors, employees or
agents shall be liable or responsible for: (i) the use which may be made of any
Letter of Credit or for any acts or omissions of any beneficiary in connection
therewith; (ii) the validity, sufficiency or genuineness of documents or of any
endorsement thereon, even if such documents should in fact prove to be in any or
all respects invalid, insufficient, fraudulent or forged; (iii) payment by the
Issuing Bank to the beneficiary under any Letter of Credit against presentation
of documents which do not strictly comply with the terms of any Letter of Credit
(unless such payment resulted from the gross negligence or willful misconduct of
the Issuing Bank), including failure of any documents to bear any reference or
adequate reference to such Letter of Credit; (iv) any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit; or (v) any
other event or



                                       27
<PAGE>   37

circumstance whatsoever arising in connection with any Letter of Credit;
provided, however, that with respect to subparagraphs (a)(i) through (a)(v)
hereof, Company and Account Parties shall not be required to indemnify the
Issuing Bank, the other Banks and the Agent and such other persons, and the
Issuing Bank shall be liable to the Company and the Account Parties to the
extent, but only to the extent, of any direct, as opposed to consequential or
incidental, damages suffered by Company and the Account Parties which were
caused by the Issuing Bank's gross negligence, willful misconduct or wrongful
dishonor of any Letter of Credit after the presentation to it by the beneficiary
thereunder of a draft or other demand for payment and other documentation
strictly complying with the terms and conditions of such Letter of Credit.

         (b)  It is understood that in making any payment under a Letter of
Credit the Issuing Bank will rely on documents presented to it under such Letter
of Credit as to any and all matters set forth therein without further
investigation and regardless of any notice or information to the contrary. It is
further acknowledged and agreed that Company or an Account Party may have rights
against the beneficiary or others in connection with any Letter of Credit with
respect to which the Banks are alleged to be liable and it shall be a condition
of the assertion of any liability of the Banks under this Section that Company
or applicable Account Party shall contemporaneously pursue all remedies in
respect of the alleged loss against such beneficiary and any other parties
obligated or liable in connection with such Letter of Credit and any related
transactions.

         3.10 Right of Reimbursement. Each Bank agrees to reimburse the Issuing
Bank on demand (by payment to the Agent for the account of the Issuing Bank),
pro rata in accordance with their Percentages, for (i) the reasonable
out-of-pocket costs and expenses of the Issuing Bank to be reimbursed by Company
or any Account Party pursuant to any Letter of Credit Agreement or any Letter of
Credit, to the extent not reimbursed by Company or Account Party and (ii) any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, fees, expenses or disbursements of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against Issuing Bank
(in its capacity as issuer of any Letter of Credit) in any way relating to or
arising out of this Agreement, any Letter of Credit, any documentation or any
transaction relating thereto, or any Letter of Credit Agreement, except to the
extent that such liabilities, losses, costs or expenses were incurred by Issuing
Bank as a result of Issuing Bank's gross negligence or willful misconduct or
wrongful dishonor of any Letter of Credit.

              (n)  any of the Insurance Subsidiaries shall fail to maintain such
         catastrophe reinsurance as a prudent insurance company would deem
         necessary, as determined by Bank;



                                       49
<PAGE>   59



              (o)  if the operation of Company or any of its Subsidiaries shall
         become subject to the control of any Regulatory Agency, other than in
         the normal course of business;

              (p)  if any of the Insurance Subsidiaries currently rated by Best
         shall receive a rating from Best of less than A- or, if after Best has
         rated an Insurance Subsidiary, Best shall withdraw its rating for the
         Insurance Subsidiary; provided that this clause (p) shall not apply to
         an Insurance Subsidiary acquired after the Effective Date as a result
         of a Permitted Acquisition.

         9.2  Exercise of Remedies. If an Event of Default has occurred and is
continuing hereunder: (a) the Agent shall, upon being directed to do so by the
Majority Banks, declare the Revolving Credit Aggregate Commitment terminated;
(b) the Agent shall, upon being directed to do so by the Majority Banks, declare
the entire unpaid principal Indebtedness, including the Notes, immediately due
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
available to be drawn at any time prior to the stated expiry of all outstanding
Letters of Credit, and (e) the Agent shall, if directed to do so by the Majority
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 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



                                       50
<PAGE>   60

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 but not
trust accounts) 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 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



                                       51
<PAGE>   61

         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, 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).

<PAGE>   62

         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




                                       53
<PAGE>   63



         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 (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 deemed
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



                                       54
<PAGE>   64

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, 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



                                       55
<PAGE>   65

         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 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 deemed to be
correct absent 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 deemed 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



                                       56
<PAGE>   66

(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 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 deemed correct, absent manifest error.

         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 or
Section 11.7 (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.

<PAGE>   67



         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 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 Agent. 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



                                       58
<PAGE>   68


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


                                       59

         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 30, 1999, 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 are 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


                                       60
<PAGE>   70

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 event of its failure
to do so). Agent shall also furnish the Banks, promptly upon receipt, with
copies of all other notices or other information required to be provided by
Company hereunder.

         12.11 Agent's Authorization; Action by Banks. Except as otherwise
expressly provided herein, whenever the Agent is authorized and empowered
hereunder on behalf of the Banks to give any approval or consent, or to make any
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.

13.      MISCELLANEOUS

         13.1 Accounting Principles. Where the character or amount of any asset

of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

         13.4 Interest. In the event the obligation of Company to pay interest
on the principal balance of the Notes is or becomes in excess of the maximum
interest rate which Company is permitted by law to contract or agree to pay,
giving due consideration to the execution date of this Agreement, then, in that
event, the rate of interest applicable with respect to such Bank's Percentage

         13.8 Successors and Assigns; Participations; Assignments.

         (a)  This Agreement shall be binding upon and shall inure to the
benefit 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 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



                                       64
<PAGE>   74

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 (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



                                       65
<PAGE>   75

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 (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


                                       66
<PAGE>   76

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 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



                                       67
<PAGE>   77

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 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
affect or reduce the rights of any Bank or the Agent under Section 11.7 hereof.

         13.15 WAIVER OF JURY TRIAL. THE BANKS, THE AGENT AND THE COMPANY 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 AGREEMENT OR ANY
RELATED INSTRUMENT OR AGREEMENT 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 COMPANY
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



                                       68
<PAGE>   78

THE BANKS AND THE AGENT OR COMPANY EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY
ALL OF THEM.

         13.16 Complete Agreement; Conflicts. This Agreement, the Notes, any
Requests for Revolving Credit Advance and the Loan Documents contain the entire
agreement of the parties hereto, superseding all prior agreements, discussions
and understandings relating to the subject matter hereof, and none of the
parties shall be bound by anything not expressed in writing. In the event of any
conflict between the terms of this Agreement and the other Loan Documents, this
Agreement shall govern.

         13.17 Severability. In case any one or more of the obligations of
Company under this Agreement, the Notes or any of the other Loan Documents shall
be invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining obligations of Company shall not in any way
be affected or impaired thereby, and such invalidity, illegality or
unenforceability in one jurisdiction shall not affect the validity, legality or
enforceability of the obligations of Company under this Agreement, the Notes or
any of the other Loan Documents in any other jurisdiction.

         13.18 Table of Contents and Headings. The table of contents and the
headings of the various subdivisions hereof are for convenience of reference
only and shall in no way modify or affect any of the terms or provisions hereof.

         13.19 Construction of Certain Provisions. If any provision of this
Agreement or any of the Loan Documents refers to any action to be taken by any
Person, or which such Person is prohibited from taking, such provision shall be
applicable whether such action is taken directly or indirectly by such Person,
whether or not expressly specified in such provision.

         13.20 Independence of Covenants. Each covenant hereunder shall be given
independent effect (subject to any exceptions stated in such covenant) so that
if a particular action or condition is not permitted by any such covenant
(taking into account any such stated exception), the fact that it would be
permitted by an exception to, or would be otherwise within the limitations of,
another covenant shall not avoid the occurrence of a Default or an Event of
Default.

         13.21 Reliance on and Survival of Various Provisions. All terms,
covenants, agreements, representations and warranties of Company or any party to
any of the Loan Documents made herein or in any of the Loan Documents or in any
certificate, report, financial statement or other document furnished by or on
behalf of Company or any Subsidiary in connection with this Agreement or any of
the Loan Documents shall be deemed to have been relied upon by the Banks,
notwithstanding any investigation heretofore or hereafter made by any Bank or on
such Bank's behalf, and those covenants and agreements of Company set forth in
Section 11.6 hereof (together with any other indemnities of Company or any
Subsidiary contained elsewhere in this Agreement or in any of the other Loan
Documents) and of Banks set forth in Section 12.9 hereof shall survive the
repayment in full of the Indebtedness and the termination of the Revolving
Credit Aggregate Commitment.
