         Advance, for which the Request for Advance must be delivered by 12:00
         p.m. (Detroit time) on such proposed date for Advances;

                  (c) on the proposed date of such Revolving Credit Advance,
         after giving effect to all Advances and all Letters of Credit requested
         by any of the Borrowers on such date of determination, the sum of (x)
         the aggregate outstanding principal amount of all Advances of the
         Revolving Credit and of the Swing Line on such date plus (y) the
         outstanding Letter of Credit Obligations on such date shall not exceed
         the then applicable Revolving Credit Available Commitment; provided
         however, that, in the case of any Advance being applied to refund an
         outstanding Advance, the aggregate principal amount of such Advances to
         be refunded shall not be included for purposes of calculating
         availability under this Section 2.3(c);

                  (d) in the case of a Prime-based Advance, the principal amount

                                    Credit have been satisfied, and shall remain
                                    satisfied to the date of such Advance (both
                                    before and after giving effect to such
                                    Advance);

                       (iii)        there is no Default or Event of Default in
                                    existence, and none will exist upon the
                                    making of such Advance (both before and
                                    after giving effect to such Advance);

                        (iv)        the representations and warranties contained

                                    after giving effect to such Advance); and

                         (v)        the execution of such Request for Advance

         person (an "Authorized Representative") previously authorized (in a
         writing delivered to the Agent) by the Borrowers to make such requests
         and, in the event Agent, acting on behalf of the Revolving Credit
         Banks, makes any such Advance upon a telephone request, the Authorized
         Representative shall fax to Agent, on the same day as such telephone
         request, a Request for Advance. The Borrowers hereby authorize Agent to
         disburse Advances under this Section 2.3 pursuant to the telephone
         instructions of any person purporting to be an Authorized
         Representative. Notwithstanding the foregoing, each of the Borrowers
         acknowledges that the Borrowers shall bear all risk of loss resulting
         from disbursements made upon any telephone request by any person
         purporting to be an Authorized Representative. Each telephone request
         for an Advance shall constitute a certification of the matters set
         forth in the Request for Revolving Credit Advance form as of the date
         of such requested Advance.

         2.4      Disbursement of Advances.

                  (a) Upon receiving any Request for Revolving Credit Advance
         from a Borrower under Section 2.3 hereof, Agent shall promptly notify
         each Revolving Credit Bank by wire, telex or telephone (confirmed by
         wire, telecopy or telex) of the amount of such Advance to be made and
         the date such Advance is to be made by said Revolving Credit Bank
         pursuant to its Percentage of such Advance. Unless such Revolving
         Credit Bank's commitment to make Advances of the Revolving Credit
         hereunder shall have been suspended or terminated in accordance with
         this Agreement, each such Revolving Credit Bank shall make available
         the amount of its Percentage of each Advance in immediately available
         funds to Agent, at the office of Agent located at One Detroit

         Center, 500 Woodward Avenue, Detroit, Michigan 48226 not later than
         3:00 p.m. (Detroit time) on the date of such Advance.

                  (b) Subject to submission of an executed Request for Revolving
         Credit Advance by the applicable Borrower without exceptions noted in
         the compliance certification therein, Agent shall make available to
         such Borrower the aggregate of the amounts so received by it from the
         Revolving Credit Banks 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 such Borrower maintained with Agent or to such other account
         or third party as such Borrower may reasonably direct.

                  (c) Agent shall deliver the documents and papers received by
         it for the account of each Revolving Credit Bank to such Revolving
         Credit Bank or upon its order. Unless Agent shall have been notified by
         any Revolving Credit Bank prior to the date of any proposed Revolving
         Credit Advance that such Revolving Credit Bank does not intend to make
         available to Agent such Revolving Credit Bank's Percentage of such
         Advance, Agent may assume that such Revolving Credit Bank has made such
         amount available to Agent on such date and in such currency, as
         aforesaid and may, in reliance upon such assumption, make available to
         the applicable Borrower a corresponding amount. If such amount is not
         in fact made available to Agent by such Revolving Credit Bank, as
         aforesaid, Agent shall be entitled to recover such amount on demand
         from such Revolving Credit Bank. If such Revolving Credit Bank does not
         pay such amount forthwith upon Agent's demand therefor, the Agent shall
         promptly notify the Borrowers, and the Borrowers shall pay such amount
         to Agent. Agent shall also be entitled to recover from such Revolving
         Credit Bank or the Borrowers, 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 such Borrower, to the
         date such amount is recovered by Agent, at a rate per annum equal to:

                         (i)        in the case of such Revolving Credit Bank,
                                    for the first two (2) Business Days such
                                    amount remains unpaid, with respect to
                                    Prime-based Advances, the Federal Funds
                                    Effective Rate, and 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 as a result of
                                    such failure to deliver funds hereunder) of
                                    carrying such amount and thereafter, at the
                                    rate of interest then applicable to such
                                    Revolving Credit Advances; and

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

and subject to the conditions hereinafter set forth (including without
limitation Section 2.5(c) and 2.5(e) hereof), make one or more advances (each
such advance being a "Swing Line Advance") to any Borrower, from time to time on
any Business Day during the period from the date hereof to (but excluding) the
Revolving Credit Maturity Date in an amount not to exceed at any time
outstanding the Swing Line Maximum Amount. All Swing Line Advances shall be
evidenced by the Swing Line Note, under which advances, repayments and
readvances may be made, subject to the terms and conditions of this Agreement.
Each Swing Line Advance shall mature and the principal amount thereof shall be
due and payable by the Borrowers on the last day of the Interest Period
applicable thereto. In no event whatsoever shall any outstanding Swing Line
Advance be deemed to reduce, modify or affect any Revolving Credit Bank's
commitment to make Revolving Credit Advances based upon its Percentage.

                  (b) Accrual of Interest. Each Swing Line Advance shall, from
time to time after the date of such Advance, bear interest at its Applicable
Interest Rate. The amount and date of each Swing Line Advance, its Applicable
Interest Rate, its Interest Period, if any, and the amount and date of any
repayment shall be noted on Swing Line Bank's account maintained pursuant to
Section 2.5(a), which records will be conclusive evidence thereof, absent
manifest error; provided, however, that any failure by the Swing Line Bank to
record any such information shall not relieve applicable Borrower of its
obligation to repay the outstanding principal amount of such Advance, all
interest accrued thereon and any amount payable with respect thereto in
accordance with the terms of this Agreement and the other Loan Documents.

                  (c) Requests for Swing Line Advances. A Borrower may request a
Swing Line Advance only after the delivery to Swing Line Bank of a Request for
Swing Line Advance executed by a person authorized (in a writing a copy of which

subject to the following and to the remaining provisions hereof:

         forth the information required in the Request for Advance, including
         without limitation:

                                  (B) whether such Swing Line Advance is to be a
                  Prime-based Advance or a Quoted Rate Advance; and

                                  (C) in the case of a Quoted Rate Advance, the

                        (ii) on the proposed date of such Swing Line Advance,
         after giving effect to all Swing Line Advances requested by any of the

         any of the Borrowers on such date of determination, the sum of (x) the
         aggregate outstanding principal amount of all Advances of the Revolving
         Credit and of the Swing Line on such date plus (y) the outstanding
         Letter of Credit Obligations on such date shall not exceed the then
         applicable Revolving Credit Available Commitment;

                        (iv) in the case of a Prime-based Advance, the principal
         amount of the initial funding of such Advance, as opposed to any
         refunding or conversion thereof, shall be at least Fifty Thousand

                         (v) in the case of a Quoted Rate Advance, the principal

         Thousand Dollars ($50,000) (or a larger integral multiple of Fifty
         Thousand Dollars ($50,000)), and at any one time there shall not be in
         effect more than four (4) Applicable Interest Rates and Interest

                       (vii) each Request for Swing Line Advance, once delivered

         constitute and include a certification by the applicable Borrower as of
         the date thereof that:

                           (A) both before and after such Swing Line Advance,
                  the obligations of the Loan Parties set forth in this
                  Agreement and the other Loan Documents, are valid, binding and
                  enforceable obligations of such Loan Parties;

                           (B) all conditions to the making of Swing Line
                  Advances have been satisfied (both before and after giving
                  effect to such Advance);

                           (C) both before and after the making of such Swing
                  Line Advance, there is no Default or Event of Default in
                  existence; and

                           (D) both before and after such Swing Line Advance,

                                       25
<PAGE>   34

              (d)    Disbursement of Swing Line Advances. Subject to submission
of an executed Request for Swing Line Advance by a Borrower without exceptions
noted in the compliance certification therein and to the other terms and
conditions hereof, Swing Line Bank shall make available to the applicable
Borrower the amount so requested, in like funds and currencies, not later than
4:00 p.m. (Detroit time) on the date of such Advance by credit to an account of
the applicable Borrower maintained with Agent or to such other account or third
party as the applicable Borrower may reasonably direct in writing.

Swing Line Bank shall promptly notify Agent of any Swing Line Advance by
telephone, telex or telecopier.

              (e)    Refunding of or Participation Interest in Swing Line
Advances.

                   (i)       The Agent, at any time in its sole and absolute
discretion, may on behalf of the applicable Borrower (which hereby irrevocably
directs the Agent to act on its behalf) request each of the Revolving Credit
Banks (including the Swing Line Bank in its capacity as a Revolving Credit Bank)
to make an Advance of the Revolving Credit to such Borrower, in an amount equal
to such Revolving Credit Bank's Percentage of the principal amount of the
aggregate Swing Line Advances outstanding on the date such notice is given (the
"Refunded Swing Line Advances"); provided however that Swing Line Advances which
are carried at the Quoted Rate which are converted to Revolving Credit Advances
at the request of the Agent at a time when no Default or Event of Default has
occurred and is continuing, shall not be subject to Section 12.1 and no losses,
costs or expenses may be assessed by the Swing Line Bank against any Borrower or
the Revolving Credit Banks as a consequence of such conversion. In the case of
each Refunded Swing Line Advance the applicable Advance of the Revolving Credit
used to refund such Swing Line Advance shall be a Prime-based Advance. In
connection with the making of any such Refunded Swing Line Advances or the
purchase of a participation interest in Swing Line Advances under Section
2.5(e)(ii) hereof, the Swing Line Bank shall retain its claim against the
Borrowers for any unpaid interest or fees in respect thereof. Unless any of the
events described in Section 10.1(j) hereof shall have occurred (in which event
the procedures of subparagraph (ii) of this Section 2.5(e) shall apply) and
regardless of whether the conditions precedent set forth in this Agreement to
the making of an Advance of the Revolving Credit are then satisfied but subject
to Section 2.5(e)(iii), each Revolving Credit Bank shall make the proceeds of
its Advance of the Revolving Credit available to the Agent for the benefit of
the Swing Line Bank at the office of the Agent specified in Section 2.4(a)
hereof prior to 11:00 a.m. Detroit time on the Business Day next succeeding the
date such notice is given, in immediately available funds. The proceeds of such
Advances of the Revolving Credit shall be immediately applied to repay the
Refunded Swing Line Advances in accordance with the provisions of Section 11.1
hereof.

                   (ii)      If, prior to the making of an Advance of the
Revolving Credit pursuant to subparagraph (i) of this Section 2.5(e), one of the
events described in Section 10.1(j) hereof shall have occurred, each Revolving
Credit Bank will, on the date such Advance of the Revolving Credit was to have
been made, purchase from the Swing Line Bank an undivided

                                       26

<PAGE>   35

participating interest in each Refunded Swing Line Advance in an amount equal to
its Percentage of such Refunded Swing Line Advance. Each Revolving Credit Bank
within the time periods specified in Section 2.5(e)(i) hereof, as applicable,
shall immediately transfer to the Agent, in immediately available funds, the
amount of its participation and upon receipt thereof the Agent will deliver to
such Revolving Credit Bank a Swing Line Participation Certificate in the form of
Exhibit F evidencing such participation.

                   (iii)     Each Revolving Credit Bank's obligation to make
Advances of the Revolving Credit and to purchase participation interests in
accordance with clauses (i) and (ii) of this Section 2.5(e) shall be absolute
and unconditional and shall not be affected by any circumstance, including,
without limitation, (i) any set-off, counterclaim, recoupment, defense or other
right which such Revolving Credit Bank may have against Swing Line Bank, the
Borrowers or any other Person for any reason whatsoever; (ii) the occurrence or
continuance of any Default or Event of Default; (iii) any adverse change in the
condition (financial or otherwise) of the Borrowers or any other Person; (iv)
any breach of this Agreement by any Borrower or any other Person; (v) any
inability of the Borrowers to satisfy the conditions precedent to borrowing set
forth in this Agreement on the date upon which such participating interest is to
be purchased; (vi) the termination of the Revolving Credit Aggregate Commitment
hereunder; or (vii) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing. If any Revolving Credit Bank
does not make available to the Agent the amount required pursuant to clause (i)
or (ii) above, as the case may be, the Agent shall be entitled to recover such
amount on demand from such Revolving Credit Bank, together with interest thereon
for each day from the date of non-payment until such amount is paid in full (x)
for the first two (2) Business Days such amount remains unpaid, at the Federal
Funds Effective Rate and (y) thereafter, at the rate of interest then applicable
to such Swing Line Advances.

         Notwithstanding the foregoing however, no Revolving Credit Bank shall
be required to make any Revolving Credit Advance to refund a Swing Line Advance
or to purchase a participation in a Swing Line Advance if prior to the making of
the Swing Line Advance by the Swing Line Bank, the Agent had obtained actual
knowledge that an Event of Default had occurred and was continuing; provided,
however that the obligation of the Revolving Credit Banks to make such Revolving
Credit Advances shall be reinstated upon the date of which such Event of Default
has been waived by the requisite Revolving Credit Banks, as applicable.

         2.6  Prime-based Interest Payments. Interest on the unpaid balance of
all Prime-based Advances of the Revolving Credit and all Swing Line Advances
carried at the Prime-based Rate from time to time outstanding shall accrue from
the date of such Advance to the Revolving Credit Maturity Date (and until paid),
at a per annum interest rate equal to the Prime-based Rate, and shall be payable
in immediately available funds quarterly in arrears commencing on the first day
of the calendar quarter next succeeding the calendar quarter during which the
initial Advance of the Revolving Credit or Swing Line Advance, as the case may
be, is made and on the first day of each calendar quarter thereafter. Interest
accruing at the Prime-based Rate shall be computed on the basis of a 360 day
year and assessed for the actual number of days elapsed, and in such

                                       27

<PAGE>   36

computation effect shall be given to any change in the interest rate resulting
from a change in the Prime-based Rate on the date of such change in the
Prime-based Rate.

         2.7      Eurocurrency-based Interest Payments and Quoted Rate Interest
Payments.

         (a) Interest on each Eurocurrency-based Advance of the Revolving Credit
shall accrue at the Eurocurrency-based Rate and shall be payable in immediately
available funds on the last day of the Interest Period applicable thereto (and,
if any Interest Period shall exceed three months, then on the last Business Day
of the third month of such Interest Period, and at three month intervals
thereafter). Interest accruing at the Eurocurrency-based Rate shall be computed
on the basis of a 360 day year and assessed for the actual number of days
elapsed from the first day of the Interest Period applicable thereto to but not
including the last day thereof.

         (b) Interest on each Quoted Rate Advance of the Swing Line shall accrue
at its Quoted Rate and shall be payable in immediately available funds on the
last day of the Interest Period applicable thereto. Interest accruing at the
Quoted Rate shall be computed on the basis of a 360 day year and assessed for
the actual number of days elapsed from the first day of the Interest Period
applicable thereto to, but not including the last day thereof.

         2.8 Interest Payments on Conversions. Notwithstanding anything to the
contrary in the preceding sections, all accrued and unpaid interest on any
Advance converted pursuant to Section 2.3 hereof shall be due and payable in
full on the date such Advance is converted.

         2.9 Interest on Default. In the event and so long as any Event of
Default shall exist, in the case of any Event of Default under Sections 10.1(a),
10.1(b) or 10.1(j), immediately upon the occurrence thereof, and in the case of
all other Events of Default, upon notice from the Majority Banks, interest shall
be payable daily on all Eurocurrency-based Advances of the Revolving Credit and
Quoted Rate Advances from time to time outstanding (and all other monetary
obligations of the Borrowers hereunder and under the other Loan Documents) at a
per annum rate equal to the Applicable Interest Rate plus two percent (2%) for
the remainder of the then existing Interest Period, if any, and at all other
such times, with respect to Prime-based Advances from time to time outstanding,
at a per annum rate equal to the Prime-based Rate plus two percent (2%).

         2.10 Prepayment of Revolving Credit Advances. (a) The Borrowers may
prepay all or part of the outstanding balance of any Prime-based Advance(s) of
the Revolving Credit at any time, provided that the amount of any partial
prepayment shall be at least Two Hundred Fifty Thousand Dollars ($250,000) and,
after giving effect to any such partial prepayment, the aggregate balance of
Prime-based Advance(s) of the Revolving Credit remaining outstanding, if any,
shall be at least Two Hundred Fifty Thousand Dollars ($250,000). The Borrowers
may prepay all or part of any Eurocurrency-based Advance (subject to not less
than two (2) Business Days' notice to Agent) provided that the amount of any
such partial prepayment shall be Five Hundred Thousand Dollars ($500,000), after
giving effect to any such partial prepayment, the unpaid portion of such Advance
which is refunded or converted under Section 2.3 hereof shall be

                                       28

<PAGE>   37

at least Five Hundred Thousand Dollars ($500,000); provided further, however
that if the prepayment of a Eurocurrency-based Advance is made on a day other
than the last Business Day of the then current Interest Period applicable to
such Eurocurrency-based Advance, then, pursuant to Section 12.1, the Borrowers
shall compensate the Revolving Credit Banks for any losses.

                  (b) The Borrowers may prepay all or part of the outstanding
balance of any Swing Line Advance carried at the Prime-based Rate at any time,
provided that the amount of any partial prepayment shall be at least Twenty Five
Thousand Dollars ($25,000) and, after giving effect to any such partial
prepayment, the aggregate balance of such Swing Line Advances remaining
outstanding, if any, shall be at least One Hundred Thousand Dollars ($100,000).
The Borrowers may prepay all or part of any Swing Line Advances carried at the
Quoted Rate (subject to not less than two (2) Business Days' notice to Swing
Line Bank and Agent), provided that the amount of any such partial payment shall
be at least Twenty Five Thousand Dollars ($25,000), after giving effect to any
such partial prepayment, and the unpaid portion of such Advance which is
refunded or converted under Section 2.5(c) hereof shall be at least Twenty Five
Thousand Dollars ($25,000); provided further, however that if the prepayment of
a Quoted Rate Advance is made on a day other than the last Business Day of the
then current Interest Period applicable to such Quoted Rate Advance, then,
pursuant to Section 12.1, the Borrowers shall compensate the Swing Line Bank for
any losses.

                  (c) Any prepayment made in accordance with this Section shall
be subject to Section 12.1 hereof, but otherwise without premium, penalty or
prejudice to the right to readvance under the terms of this Agreement.

         2.11 Prime-based Advance in Absence of Election or Upon Default.
Subject to Section 12.3 and unless the Majority Banks shall have otherwise
agreed, if upon the expiration of any Interest Period applicable to any
Eurocurrency-based Advance

                  (a) the applicable Borrower has failed to timely select a new
         Interest Period to be applicable to such Eurocurrency-based Advance,
         such Borrower shall be deemed to have elected to convert such
         Eurocurrency-based Advance into a Prime-based Rate Advance effective as
         of the expiration date of such Interest Period; and

                  (b) on such day a Default or Event of Default shall exist,
         then subject to Sections 2.9 and 12.1 hereof, and notwithstanding the
         foregoing clause (a), at the election of the Majority Banks the
         outstanding principal amount of such Eurocurrency-based Advance shall
         be converted to a Prime-based Advance and the Agent shall promptly
         notify Borrowers of such action.

         2.12 Revolving Credit Facility Fee. From the Effective Date to the
Revolving Credit Maturity Date, the Borrowers shall pay to the Agent for
distribution to the Revolving Credit Banks pro-rata in accordance with their
respective Percentages, a Revolving Credit Facility Fee quarterly in arrears
commencing October 1, 1999 (in respect of the prior fiscal quarter or portion

                                       29

<PAGE>   38

thereof), and on the first day of each fiscal quarter thereafter. The Revolving
Credit Facility Fee shall be equal to the Revolving Credit Aggregate Commitment
(whether used or unused) times the Applicable Fee Percentage 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. Upon receipt of such payment, Agent shall make prompt payment to
each Revolving Credit Bank of its share of the Revolving Credit Facility Fee
based upon its respective Percentage. It is expressly understood that the
Revolving Credit Facility Fees described in this Section are not refundable
under any circumstances.

         2.13 Optional Reduction or Termination of Revolving Credit Aggregate
Commitment. Provided that no Default or Event of Default has occurred and is
continuing, the Borrowers may upon at least five Business Days' prior written
notice to the 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 Five Million
Dollars ($5,000,000) 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 on the amount of the reduction in
the Revolving Credit Commitment Fee to the date of such reduction; (iii) the
Borrowers shall prepay in accordance with the terms hereof the amount, if any,
by which the aggregate unpaid principal amount of Advances outstanding
hereunder, plus the aggregate undrawn amount of outstanding Letter of Credit
Obligations, exceeds the amount of the then applicable Revolving Credit
Aggregate Commitment as so reduced, together with interest thereon to the date
of prepayment; and (iv) no reduction shall reduce the Revolving Credit Aggregate
Commitment to an amount which is less than the aggregate undrawn amount of any
Letters of Credit outstanding at such time; provided, however that if the
termination or reduction of the Revolving Credit Aggregate Commitment requires
the prepayment of a Eurocurrency-based Advance or a Quoted Rate Advance and such
termination or reduction is made on a day other than the last Business Day of
the then current Interest Period applicable to such Eurocurrency-based Advance
or such Quoted Rate Advance, then, pursuant to Section 12.1, the Borrowers shall
compensate the Revolving Credit Banks for any losses. In the event the Revolving
Credit Aggregate Commitment is reduced to an amount which is less than the then
current Swing Line Maximum Amount, the then current Swing Line Maximum Amount
shall be automatically reduced to an amount equal to the Revolving Credit
Aggregate Commitment as so reduced and the Borrowers shall prepay in accordance
with the terms hereof, the amount by which the then outstanding Swing Line
Advances exceeds the Swing Line Maximum Amount as so reduced. Reductions of the
Revolving Credit Aggregate Commitment and any accompanying prepayments of
Advances of the Revolving Credit shall be distributed by Agent to each Revolving
Credit Bank in accordance with such Revolving Credit Bank's Percentage thereof,
and will not be available for reinstatement by or readvance to the Borrowers and
any accompanying prepayments of Advances of the Swing Line shall be distributed
by the Agent to the Swing Line Bank and will not be available for reinstatement
by or readvance to the Borrowers. Any reductions of the Revolving Credit
Aggregate Commitment hereunder shall reduce each Revolving Credit Bank's portion
thereof proportionately (based on the applicable Percentages), and shall be
permanent and irrevocable. Any payments made pursuant to this

                                       30

<PAGE>   39

Section shall be applied first to outstanding Prime-based Advances under the
Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate,
next to Eurocurrency-based Advances of the Revolving Credit and then to Swing
Line Advances carried at the Quoted Rate.

         2.14 Application of Advances. Advances of the Revolving Credit
(including Swing Line Advances) shall be available, subject to the terms hereof,
to finance the Smartflex Acquisition and Permitted Acquisitions, to fund working
capital needs, or other general corporate purposes of the Borrowers; provided,
however, that no Borrower other than Newco may request Advances to finance any
portion of the purchase price of the Smartflex Acquisition.

         2.15 Extension of Revolving Credit Maturity Date. (a) Provided that no
Default or Event of Default has occurred and is continuing, Borrowers 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 July 1, but not before June 1 of each year beginning
in 2000, 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 July 30 of such 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 such additional one year period, the term
Revolving Credit Maturity Date shall mean such extended date and Agent shall
promptly notify the Borrowers 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 July 30 of
such 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 Borrowers to
request extensions thereof under this Section 2.15), and (y) the commitments of
the Revolving Credit 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 Borrowers thereof.

         2.16 Mandatory Reduction of Revolving Credit Aggregate Commitment. On
the Smartflex Expiration Date, the Revolving Credit Aggregate Commitment shall
be permanently reduced by the amount of the Blocked Commitment, unless the
Smartflex Acquisition has been consummated by such date. Any reduction of the
Revolving Credit Aggregate Commitment hereunder shall reduce each Revolving
Credit Bank's portion thereof proportionately (based on the applicable
Percentages), and shall be permanent and irrevocable.

Section 3.6 hereof, and no law, rule, regulation, request or directive (whether
or not having the force of law) shall prohibit or request that Issuing Bank
refrain from issuing, or any Revolving Credit Bank refrain from taking an
assignment of its Percentage of, the Letter of Credit requested or letters of
credit generally;

                  (g)     there shall have been no introduction of or change in
the interpretation of any law or regulation that would make it unlawful or
unduly burdensome for the Issuing Bank to issue or any Revolving Credit Bank to
take an assignment of its Percentage of the requested Letter of Credit, no
suspension of or material limitation on trading on the New York Stock Exchange
or any other national securities exchange, no declaration of a general banking
moratorium by banking authorities in the United States, Michigan or the
respective jurisdictions in which the Revolving Credit Banks, the applicable
Account Party and the beneficiary of the requested Letter of Credit are located,
and no establishment of any new restrictions on transactions involving letters
of credit or on banks materially affecting the extension of credit by banks; and

                  (h)     Issuing Bank shall have received the issuance fees
required in connection with the issuance of such Letter of Credit pursuant to
Section 3.4 hereof.

Each Letter of Credit Agreement submitted to Issuing Bank pursuant hereto shall
constitute the certification by the Borrowers and the Account Party of the
matters set forth in Section 3.2 (a) through (d) hereof. The Agent shall be
entitled to rely on such certification without any duty of inquiry.

         3.3 Notice. The Issuing Bank will deliver to the Agent, concurrently
with or promptly following its delivery of any Letter of Credit, a true and
complete copy of each Letter of Credit. Promptly upon its receipt thereof, Agent
shall give notice, substantially in the form attached as Exhibit C, to each
Revolving Credit Bank of the issuance of each Letter of Credit, specifying the
amount thereof and the amount of such Lender's Percentage thereof.

                                       33

         3.4 Letter of Credit Fees. The Borrowers shall pay to the Agent for
distribution to the Revolving Credit Banks in accordance with their Percentages,
letter of credit fees as follows:

                  (a)     A per annum letter of credit fee with respect to the
undrawn amount of each Letter of Credit issued pursuant hereto (based on the
Amount of each Letter of Credit) in the amount of the Applicable Fee Percentage
(determined with reference to Schedule 1.1 to this Agreement).

                  (b)     A letter of credit facing fee in the amount equal to
one-eighth percent (0.125%) per annum on the undrawn amount of each Letter of
Credit to be retained by Issuing Bank for its own account.

                  (c)     Subject to Section 12.6 hereof, if any change in any
law or regulation or in the interpretation thereof by any court or
administrative or governmental authority charged with the administration thereof
shall either (i) impose, modify or cause to be deemed applicable any reserve,
special deposit, limitation or similar requirement against letters of credit
issued or participated in by, or assets held by, or deposits in or for the
account of, Issuing Bank or any Bank or (ii) impose on Issuing Bank or any Bank
any other condition regarding this Agreement, the Letters of Credit or any
participations in such Letters of Credit, and the result of any event referred
to in clause (i) or (ii) above shall be to increase the cost or expense to
Issuing Bank or such Bank 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 expenses resulting from such events), then, upon demand by
the Issuing Bank or such Bank, as the case may be, the applicable Account Party
shall, within thirty (30) days following demand for payment, pay to Issuing Bank
or such Bank, as the case may be, from time to time as specified by the Issuing
Bank or such Bank, additional amounts which shall be sufficient to compensate
the Issuing Bank or such Bank for such increased cost and expense, together with
interest on each such amount from ten 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, submitted to the
applicable Account Party, shall be conclusive evidence, absent manifest error,
as to the amount thereof.

                  (d)     All payments by the Borrowers to the Agent for
distribution to the Issuing Bank or the Revolving Credit Banks under this
Section 3.4 shall be made in immediately available funds at the Issuing Office
or such other office of the Agent as may be designated from time to time by
written notice to Borrowers by the Agent. The fees described in clauses (a) and
(b) above shall be nonrefundable under all circumstances, shall be payable
annually in advance (or such lesser period, if applicable, for Letters of Credit
issued with stated expiration dates of less than one year) upon the issuance of
each such Letter of Credit, and shall be calculated on the basis of a 360 day
year and assessed for the actual number of days from the date of the issuance
thereof to the stated expiration thereof.

                                       34

<PAGE>   43

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

         3.6 Drawings and Demands for Payment Under Letters of Credit.

                  (a)     The Borrowers and each applicable Account Party agree
to pay to 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 expenses paid or incurred by
the Agent relative thereto. Unless the Borrowers 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 Borrowers or the applicable Account Party, and the
Borrowers or the applicable Account Party shall be deemed to have elected to
substitute for its reimbursement obligation, a Prime-based Advance of the
Revolving Credit for the account of the Revolving Credit 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
deemed disbursed notwithstanding any failure to satisfy any conditions for
disbursement of any Advance set forth in Section 2 hereof and, to the extent of
the Advances so disbursed, the reimbursement obligation of the Borrower or the
applicable Account Party 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 Borrowers and the applicable Account
Party on the date such draft or demand is honored, and to each Revolving Credit
Bank on such date unless the Borrowers or applicable Account Party shall have
satisfied its reimbursement obligation under Section 3.6(a) hereof by payment to
the Agent on such date. The Issuing Bank shall further use reasonable efforts to
provide notice to the Borrowers or applicable Account Party prior to honoring
any such draft or other demand for payment, but such notice, or the failure to
provide such notice, shall not affect the rights or obligations of the Issuing
Bank with respect to any Letter of Credit or the rights and obligations of the
parties hereto, including without limitation the obligations of the Borrowers or
applicable Account Party under Section 3.6(a) hereof.

                  (c)     Upon issuance by the Issuing Bank of each Letter of
Credit hereunder, each Revolving Credit Bank shall automatically acquire a pro
rata participation interest in such Letter of Credit and each related Letter of
Credit Payment based on its respective Percentage. Each Revolving Credit Bank,
on the date a draft or demand under any Letter of Credit is honored (or the next
succeeding Business Day if the notice required to be given by Agent to the
Revolving Credit Banks under Section 3.6(b) hereof is not given to the Revolving
Credit Banks prior to 2:00 p.m. (Detroit time) on such date of draft or demand),
shall make its Percentage of

                                       35

<PAGE>   44

the amount paid by the Issuing Bank, and not reimbursed by the Borrowers or
applicable Account Party on such day, in immediately available funds at the
principal office of the Agent for the account of Issuing Bank. If and to the
extent such Revolving Credit Bank shall not have made such pro rata portion
available to the Agent, such Bank, the Borrowers 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 at a per
annum rate equal to the interest rate applicable during such period to the
related Advance deemed to have been disbursed under Section 3.6(a) in respect of
the reimbursement obligation of the Borrowers and the applicable Account Party,
as set forth in Section 2.4(c)(i) or 2.4(c)(ii) hereof, as the case may be. If
such Revolving Credit Bank shall pay such amount to the Agent for the account of
Issuing Bank together with such interest, such amount so paid shall be deemed to
constitute an Advance by such Revolving Credit Bank disbursed in respect of the
reimbursement obligation of the Borrowers or applicable Account Party under
Section 3.6(a) hereof for purposes of this Agreement, effective as of the dates
applicable under said Section 3.6(a). The failure of any Revolving Credit Bank
to make its pro rata portion of any such amount paid by the Issuing Bank
available to the Agent for the account of Issuing Bank shall not relieve any
other Revolving Credit Bank of its obligation to make available its pro rata
portion of such amount, but no Revolving Credit Bank shall be responsible for
failure of any other Revolving Credit Bank to make such pro rata portion
available to the Agent for the account of Issuing Bank.

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

         3.7 Obligations Irrevocable. The obligations of the Borrowers and any
Account Party to make payments to Agent for the account of Issuing Bank or the
Revolving Credit Banks with respect to Letter of Credit 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 any 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 or under any of the Letter of Credit
Documents;

                  (c)     The existence of any claim, setoff, defense or other
right which the Borrowers 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 Revolving Credit Bank or any

                                       36

<PAGE>   45

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, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect;

                  (e)     Payment by the Issuing Bank to the beneficiary under
any Letter of Credit against presentation of documents which do not comply with
the terms of such Letter of Credit, including failure of any documents to bear
any reference or adequate reference to such Letter of Credit;

                  (f)     Any failure, omission, delay or lack on the part of
the Agent, Issuing Bank or any Revolving Credit 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, Issuing Bank, any Bank or any such party under
this Agreement, any of the other Loan Documents or any of the Letter of Credit
Documents, or any other acts or omissions on the part of the Agent, Issuing
Bank, any Bank or any such party; or

                  (g)     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 the Borrowers or any Account Party from the performance or
observance of any obligation, covenant or agreement contained in Section 3.6
hereof.

No setoff, counterclaim, reduction or diminution of any obligation or any
defense of any kind or nature which the Borrowers or any Account Party has or
may have against the beneficiary of any Letter of Credit shall be available
hereunder to the Borrowers or any Account Party against the Agent, Issuing Bank
or any Bank. Nothing contained in this Section 3.7 shall be deemed to prevent
the Borrowers or the Account Parties, after satisfaction in full of the absolute
and unconditional obligations of the Borrowers 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, Issuing Bank or
any Bank.

         3.8 Risk Under Letters of Credit. (a) In the administration and
handling of Letters of Credit and any security therefor, or any documents or
instruments given in connection therewith, 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 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 counsel, accountants, appraisers or

                                       37

<PAGE>   46

other experts selected by Issuing Bank with due care and Issuing Bank may rely
upon any notice, communication, certificate or other statement from the
Borrowers, 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 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 have no responsibility with respect to (i) the
obligations of the Borrowers or any Account Party or the validity, sufficiency
or enforceability of any document or instrument given in connection therewith,
or the taking of any action with respect to same, (ii) the financial condition
of, any representations made by, or any act or omission of, the Borrowers, 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 acknowledges that it has made and will
continue to make its own evaluations of the Borrowers's and the Account Parties'
creditworthiness without reliance on any representation of Issuing Bank or
Issuing Bank's officers, agents and employees.

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

         3.9 Indemnification. Each of the Borrowers 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:

                  (a)     the use which may be made of any Letter of Credit or
for any acts or omissions of any beneficiary in connection therewith;

                                       38

<PAGE>   47

                  (b)     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;

                  (c)     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;

                  (d)     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

                  (e)     any other event or circumstance whatsoever arising in
connection with any Letter of Credit;

provided, however, that with respect to subparagraphs (a) through (e) hereof,
none of the Borrowers nor any of the Account Parties shall be required to
indemnify the Issuing Bank, the other Banks and the Agent and such other persons
to the extent the claim for indemnification resulted from the Issuing Bank's
gross negligence or willful misconduct, and the Issuing Bank shall be liable to
the Borrowers and the Account Parties to the extent, but only to the extent, of
any direct, as opposed to consequential or incidental, damages suffered by the
Borrowers 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.

                  (f)     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 a Borrower 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 the applicable Borrower 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; provided however that, to
the extent that the Issuing Bank or the Banks are finally adjudicated to have
been grossly negligent or to have acted with willful misconduct, then the
Issuing Bank or the Banks, as the case may be, shall reimburse such Borrowers or
such Account Party for the reasonable costs and expenses of pursuing such
remedies.

         3.10 Right of Reimbursement. Each Bank agrees to reimburse the Issuing
Bank on demand, pro rata in accordance with its respective Percentage, for (i)
the reasonable out-of-

                                       39
<PAGE>   48

pocket costs and expenses of the Issuing Bank to be reimbursed by the Borrowers
or any Account Party pursuant to any Letter of Credit Agreement or any Letter of
Credit, to the extent not reimbursed by any Borrowers or any Account Party and
(ii) any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, fees, reasonable out-of-pocket expenses or
disbursements of any kind and nature whatsoever which may be imposed on,
incurred by or asserted against Issuing Bank 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, to the extent
not reimbursed by any Borrowers or any Account Party, 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 by the
Issuing Bank's 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.

         7.14   [RESERVED]

         7.15   No Investment Company or Margin Stock. None of the Borrowers or
any Guarantor is an "investment company" within the meaning of the Investment
Company Act of 1940, as amended. No Borrower nor any Guarantor is engaged
principally, or as one of its important activities, directly or indirectly, in
the business of extending credit for the purpose of purchasing or carrying
margin stock. None of the proceeds of any of the Advances (or any

                                       48

<PAGE>   57

Letters of Credit) will be used by any Borrower nor any other Subsidiary to
purchase or carry margin stock or will be made available by any Borrower or any
of its Subsidiaries in any manner to any other Person to enable or assist such
Person in purchasing or carrying margin stock. Terms for which meanings are
provided in Regulation U of the Board of Governors of the Federal Reserve System
or any regulations substituted therefor, as from time to time in effect, are
used in this paragraph with such meanings.

         7.16   ERISA. None of the Borrowers nor any Guarantor maintains or
contributes to any Pension Plan subject to Title IV of ERISA, except as set
forth on Schedule 7.16 hereto; and there is no accumulated funding deficiency
within the meaning of ERISA, or any existing liability with respect to any of
the Pension Plans owed to the Pension Benefit Guaranty Corporation or any
successor thereto, and no "reportable event" or "prohibited transaction", as
defined in ERISA, has occurred with respect to any Pension Plan, and all such
Pension Plans are in material compliance with the requirements of the Internal
Revenue Code and ERISA.

         7.17   Conditions Affecting Business or Properties. Neither the
respective businesses nor the properties of any Borrower, nor any Subsidiary of
any Borrower has been affected by any fire, explosion, accident, strike, lockout
or other dispute, drought, storm, hail, earthquake, embargo, Act of God or other
casualty (not covered by insurance) which is reasonably likely to have a
Material Adverse Effect, or if such event or condition were to continue for more
than ten (10) additional days would reasonably be expected to have a Material
Adverse Effect.

         7.18   Environmental and Safety Matters. Except as set forth in
Schedules 7.18 and 7.12 and except for such matters as are not likely to have a
Material Adverse Effect:

                (a)     all facilities and property owned or leased by the Loan
         Parties are owned or leased by the Loan Parties in material compliance
         with all Hazardous Material Laws;

                (b)     to the best knowledge of the Borrowers, there have been
         no past, and there are no pending or threatened

                  for information received by any Loan Party with respect to any
                  alleged violation of any Hazardous Material Law, or

                                  (ii) complaints, notices or inquiries to any
                  Loan Party regarding potential liability under any Hazardous
                  Material Law; and

                (c)     to the knowledge of the Borrowers, no conditions exist
         at, on or under any property now or previously owned or leased by the
         Loan Parties which, with the passage of time, or the giving of notice
         or both, would give rise to liability under any Hazardous Material Law.

                                       49
<PAGE>   58

         7.19 Subsidiaries. Except as disclosed on Schedule 7.19 hereto, the
Company has no Subsidiaries.

         7.20 Accuracy of Information. (a) The projections and pro forma
financial information provided to the Banks are based upon good faith estimates
and assumptions believed by management of the Borrowers to be reasonable at the
time made, it being recognized by the Banks that such financial information as
it relates to future events is not to be viewed as fact and that actual results
during the period or periods covered by such financial information may differ
from the projected results set forth therein.

              (b)  Since December 31, 1998 through the Effective Date there
has been no material adverse change in the financial condition of the Borrowers
or their respective Subsidiaries; to the best knowledge of Borrowers, none of
the Borrowers (or any of their respective Subsidiaries) has any contingent
obligations required to be disclosed under GAAP (including any liability for
taxes) not disclosed by or reserved against in the balance sheet referred to in
Section 6.6(a), except as set forth on Schedule 7.20 hereof, and as of the
Effective Date, there are no unrealized or anticipated losses from any present
commitment of Borrowers or any of their Subsidiaries which contingent
obligations and losses in the aggregate are likely to have a Material Adverse
Effect.

         7.21 Labor Relations. None of the Borrowers nor any of their respective
Subsidiaries is engaged in any unfair labor practice that could reasonably be
expected to have a Material Adverse Effect. There is (i) no unfair labor
practice complaint pending against the Borrowers, or any of their respective
Subsidiaries or, to the knowledge of Borrowers, threatened against any of them,
before the National Labor Relations Board, and no grievance or arbitration
proceeding arising out of or under any collective bargaining agreement is so
pending against any Borrower or any of its Subsidiaries or, to Borrowers'
knowledge, threatened against any of them, (ii) no strike, labor dispute,
slowdown or stoppage pending against the Borrowers or any of their respective
Subsidiaries, or, to the knowledge of Borrowers, threatened against any of them
and (iii) no union representation question existing with respect to the
employees of the Borrowers or any of their respective Subsidiaries, in each case
or in the aggregate which could reasonably be expected to have a Material
Adverse Effect.

         7.22 Solvency. After giving effect to the consummation of the
transactions contemplated by this Agreement, each Borrower and its Subsidiaries
will each be solvent, able to pay its indebtedness as it matures and will have
capital sufficient to carry on its business and all business in which it is
about to engage. This Agreement is being executed and delivered by the Borrowers
to Agent and the Banks in good faith and in exchange for fair, equivalent
consideration. After giving effect to the transactions contemplated herein, the
capital and monies remaining in the Borrowers and their Subsidiaries are not now
and will not become so unreasonably small as to preclude the Borrowers or their
Subsidiaries from carrying on their businesses. Neither of the Borrowers nor any
Subsidiary intends to nor does management of Borrowers or any Subsidiary believe
it will incur debts beyond its ability to pay as they mature. Neither of the
Borrowers nor any Subsidiary contemplates filing a petition in bankruptcy or for

                                       50

<PAGE>   59

an arrangement or reorganization under the Bankruptcy Code, nor does any
Borrower or any Subsidiary have any knowledge of any threatened bankruptcy or
insolvency proceedings against Borrowers or any Subsidiary.

         7.23 Ownership. The common stock of each Borrower and each Subsidiary
of such Borrower is as set forth in Schedule 7.23. All common stock of Borrowers
and their respective Subsidiaries are duly authorized and validly issued, fully
paid, nonassessable, free and clear of all Liens and such ownership interests
were issued in compliance with all applicable state and federal laws concerning
the issuance of such interests. Except as disclosed on Schedule 7.23, there are
no preemptive or other outstanding rights, options, warrants, conversion rights
or similar agreements or understandings for the purchase or acquisition from a
Borrower or any Subsidiary, of any ownership interests or other securities of a
Borrower or any Subsidiary.

         7.24 Year 2000 Requirement. Each of the Borrowers has reviewed and has
caused their respective Subsidiaries to review the areas in their business and
operations which could be adversely affected by, and have developed or are
developing a program to address on a timely basis, the risk that computer
applications used by the Borrowers and their respective Subsidiaries may be
unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999. Any reprogramming
required to permit the proper functioning, in and following the year 2000, of
(i) any such Borrower's or any such Subsidiary's computer systems and (ii)
equipment containing embedded microchips (including systems and equipment
supplied by others or with which such Borrower's or such Subsidiary's systems
interface) and the testing of all such systems and equipment, as so
reprogrammed, will be substantially completed by September 30, 1999. The cost to
the Borrowers and their respective Subsidiaries of such reprogramming and
testing and of the reasonably foreseeable consequences of year 2000 to the
Borrowers and their respective Subsidiaries taken as a whole (including, without
limitation, reprogramming errors and the failure of others' systems or
equipment) will not result in a Default or a Material Adverse Effect. Except for
such of the reprogramming referred to in the preceding sentence as may be

         notice or passage of time or both would permit the holder or holders
         thereto to accelerate such other indebtedness for borrowed money or
         terminate its commitment thereunder, as applicable;

              (i)  the rendering of any judgment(s) for the payment of money

         or in the aggregate against any Borrower or any Subsidiary, and such
         judgment(s) shall remain unpaid, unvacated, unbonded or unstayed by
         appeal or otherwise for a period of thirty (30) consecutive days,

         with respect thereto;

              (j)  the occurrence of a "reportable event", as defined in

         Corporation of any Pension Plan subject to Title IV of ERISA maintained
         or contributed to by or on behalf of a Borrower or any of its
         Subsidiaries for the benefit of any of its employees or for the

         trustee to administer such Pension Plan and such reportable event is
         not corrected and such determination is not revoked within sixty (60)
         days after notice thereof has been given to the plan administrator of
         such Pension Plan (without limiting any of Agent's or any Bank's other
         rights or remedies hereunder), or the institution of proceedings by the
         Pension Benefit Guaranty Corporation to terminate any such Pension Plan
         or to appoint a trustee by the appropriate United States District Court
         to administer any such Pension Plan;

         issued, enforced or levied against a substantial part of any Loan
         Party's properties, and such proceeding or petition shall not be
         dismissed, or such writ, judgment, warrant of attachment, execution or
         similar process shall not be released, vacated or fully bonded, within
         60 days after commencement, filing or levy; (B) any Loan Party admits
         the material allegations of a petition against it in any Insolvency
         Proceeding, or an order for relief (or similar order under non-U.S.
         law) is ordered in any Insolvency Proceeding; or (C) any Loan Party

                   (ii)      following an Initial Public Offering, (x) any
                             Person and Affiliates of such Person shall own or
                             control, directly or indirectly, a greater number
                             of shares of the capital stock having voting rights
                             of any of the Borrowers than are owned or

<PAGE>   73

                   (iii)     Wallace K. Tsuha, Jr. shall for any reason cease to
                             be the Chairman of the Board of each of the
                             Borrowers.

              (m)  any material provision of any Loan Document shall at any time
         for any reason cease to be valid, binding and enforceable against any
         Loan Party or the validity, binding effect or enforceability thereof
         shall be contested by any Loan Party, or any Loan Party shall deny that
         it has any or further liability or obligation under any Loan Document,
         or any such Loan Document shall be terminated, invalidated, revoked or
         set aside or in any way cease to give or provide to the Banks and the
         Agent the benefits purported to be created thereby.

         10.2 Exercise of Remedies. (a) If an Event of Default has occurred and
is continuing hereunder: (a) the Agent may, and shall, upon being directed to do
so by the Majority Banks, declare the Revolving Credit Aggregate Commitment
terminated; (b) the Agent may, and 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 Borrowers; (c) upon the occurrence of
any Event of Default specified in subsection 10.1(j), above, and notwithstanding
the lack of any declaration by Agent under preceding clause (a), the entire
unpaid principal Indebtedness, 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 Borrowers 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 may, and shall, if directed to do so by the
Majority Banks or all Banks, as applicable (subject to the terms hereof),
exercise any remedy permitted by this Agreement, the other Loan Documents or
law.

         10.3 Rights Cumulative. No delay or failure of the 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 the Banks would otherwise have.

         10.4 Waiver by Borrowers of Certain Laws. To the extent permitted by
applicable law, each Borrower 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.

                                       65

<PAGE>   74

         10.5 Waiver of Defaults. No Event of Default may be waived by the Banks
except in a writing signed by an officer of the Agent in accordance with Section
14.11 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 or the Banks in enforcing any of their rights shall
constitute a waiver of any of their rights. Company and Newco expressly agree
that this Section may not be waived or modified by the Banks or Agent by course
of performance, estoppel or otherwise.

         10.6 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 Borrowers but subject to the provisions of Section 11.4 hereof
(any requirement for such notice being expressly waived by the Borrowers), set
off and apply against any and all of the obligations of the Borrowers now or
hereafter existing under this Agreement, whether owing to such Bank or any other
Bank or the Agent, any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Bank to or for the credit or the account of any Borrower or any property
of any Borrower 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. The Borrowers hereby
grant 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 Borrowers under this Agreement and
all of the obligations of the Borrowers under each Loan Document to which it is
a party. The rights of each Bank under this Section 10.6 are in addition to the
other rights and remedies (including, without limitation, other rights of
setoff) which such Bank may have.

11.      PAYMENTS, RECOVERIES AND COLLECTIONS

         11.1      Payment Procedure.

                   (a)   All payments by the Borrowers 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 (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 the
         Borrowers prior to the date on which any payment to be made by the
         Borrowers is due that the Borrowers do not intend to remit such
         payment, the Agent may, in its sole discretion and without obligation
         to do so, assume that the Borrowers have remitted such payment when so
         due and the

                                       66

<PAGE>   75

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

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

                   (d)  All payments to be made by Borrowers under this
         Agreement or any of the Notes (including without limitation payments
         under the Swing Line Note) 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 Borrowers are compelled
         by law to make payment subject to such tax. In such event, Borrowers
         shall:

                        (i)  pay to the Agent for Agent's own account and/or, as
                             the case may be, for the account of the Banks (and,
                             in the case of Advances of the Swing Line, pay to
                             the Swing Line Bank which funded such Advances)
                             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 (including the Swing Line
                             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 Borrowers,
                             of any such taxes payable by the Borrowers.

         As used herein, the terms "tax", "taxes" and "taxation" include all
existing taxes, levies, imposts, duties, charges, fees, deductions and
withholdings and any restrictions or conditions

                                       67

<PAGE>   76

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 any of the
Borrowers, the Agent or any of the Banks).

         11.2 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 Borrowers or others
and any other sums received or collected in respect of the Indebtedness, shall
be applied, first, to the Notes and any Reimbursement Obligation on a pro rata
basis (or in such order and manner as determined by the Majority Banks), next,
to any other Indebtedness on a pro rata basis, and then, if there is any excess,
to Borrowers or the applicable Subsidiary, as the case may be. The application
of such proceeds and other sums to the Notes and any Reimbursement Obligation
shall be based on each Bank's respective Percentages, as applicable.

         11.3 Letter of Credit Liabilities For the purposes of payments and
distributions under Section 11.2 hereof, the full amount of Indebtedness on
account of any outstanding Letter of Credit shall be deemed to be then due and
owing, and the face amount of any Letter of Credit then outstanding but not
drawn upon and all Reimbursement Obligations (other than amounts attributable to
interest, fees and costs) due on any Letters of Credit that have been drawn upon
shall be considered principal owing pursuant to Indebtedness relating to Letters
of Credit and the amount outstanding under the Letters of Credit for purposes of
determining pro rata sharing or otherwise. Amounts distributable under Section
11.2 to the Banks on account of such Indebtedness under such Letters of Credit
shall be deposited in a separate interest bearing cash collateral account in the
name of and under the control of the Agent and held by the Agent, first as
security for such Letter of Credit Indebtedness and then as security for all
other Indebtedness, and the amount so deposited shall be applied to reimburse
the Revolving Credit Banks for any drawings under any Letter of Credit, and if
all letters of credit shall expire or terminate without being drawn upon, then
such amounts shall be applied to the remaining Indebtedness in the order and
manner provided under Section 11.2. Each Borrower, by its acknowledgment and
acceptance of this Agreement, hereby grants to the Agent, for the benefit of the
Banks, a lien and security interest in all such funds deposited in such separate
interest bearing collateral account, as security for the Indebtedness as set
forth above.

         11.4 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

                                       68

<PAGE>   77

recovered from such purchasing holder, the purchase shall be rescinded and the
purchase price restored to the extent of such recovery, but without interest.

12.      CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS

         12.1 Reimbursement of Prepayment Costs. If any Borrower makes any
payment of principal with respect to any Eurocurrency-based Advance or Quoted
Rate Advance on any day other than the last day of the Interest Period
applicable thereto (whether voluntarily, by acceleration, or otherwise), or if
any Borrower converts or refunds (or attempts to convert or refund) any such
Advance on any day other than the last day of the Interest Period applicable
thereto; or if any Borrower fails to borrow, refund or convert into any
Eurocurrency-based Advance or Quoted Rate Advance after notice has been given by
such Borrower to Agent in accordance with the terms hereof requesting such
Advance, or if any Borrower fails to make any payment of principal or interest
in respect of a Eurocurrency-based Advance or Quoted Rate Advance when due, the
applicable Borrower shall reimburse Agent for itself and/or on behalf of any
Bank, as the case may be, on demand for any resulting loss, cost or expense
incurred (excluding the loss of any Applicable Margin) 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 such Borrower to Agent for itself and/or on behalf of any Bank, 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 eurocurrency 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 or Quoted Rate Advance, as the case
may be, 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. Agent and Banks shall deliver to Borrowers a certificate setting
forth in reasonable detail the basis for determining such losses, costs and
expenses, which certificate shall be conclusively presumed correct, absent
manifest error.

         12.2 Eurocurrency Lending Office. For any Advance to which the
Eurocurrency-based Rate is applicable, if Agent or a Bank, as applicable, shall
designate a Eurocurrency Lending Office which maintains books separate from
those of the rest of Agent or such Bank, Agent or such Bank, as the case may be,
shall have the option of maintaining and carrying the relevant Advance on the
books of such Eurocurrency Lending Office.

                                       69

<PAGE>   78

         12.3 Circumstances Affecting Eurocurrency-based Rate Availability. If
with respect to any Interest Period, Agent or the Majority Banks (after
consultation with Agent) shall determine that, by reason of circumstances
affecting the foreign exchange and interbank markets generally, deposits in
eurodollars, in the applicable amounts are not being offered to the Agent or
such Banks for such Interest Period, then Agent shall forthwith give notice
thereof to the Borrowers. Thereafter, until Agent notifies the Borrowers that
such circumstances no longer exist, (i) the obligation of Banks to make
Eurocurrency-based Advances, and the right of the Borrowers to convert an
Advance to or refund an Advance as a Eurocurrency-based Advance, as the case may
be, shall be suspended, and (ii) the Borrowers 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 under Sections 12.1 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 Borrowers
notify Agent to the contrary within two (2) Business Days after receiving a
notice from Agent pursuant to this Section, such outstanding principal amount
shall be converted to a Prime-based Advance as of the last day of such Interest
Period.

         12.4 Laws Affecting Eurocurrency-based Advance Availability. If, after
the date of this Agreement, the introduction of, or any change in, any
applicable law, rule or regulation or in the interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof, or compliance by 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 shall forthwith give notice
thereof to the Borrowers and to Agent. Thereafter, (a) the obligations of Banks
to make Eurocurrency-based Advances and the right of any Borrower to convert an
Advance into or refund an Advance as a Eurocurrency-based Advance shall be
suspended and thereafter the Borrowers may select as Applicable Interest Rates
only those which remain available and which are permitted to be selected
hereunder, and (b) 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 the applicable Advance shall immediately be converted
to a Prime-based Advance and the Prime-based Rate shall be applicable thereto
for the remainder of such Interest Period. For purposes of this Section, a
change in law, rule, regulation, interpretation or administration shall include,
without limitation, any change made or which becomes effective on the basis of a
law, rule, regulation, interpretation or administration presently in force, the
effective date of which change is delayed by the terms of such law, rule,
regulation, interpretation or administration.

         12.5 Increased Cost of Eurocurrency-based Advances. If the adoption
after the date of this Agreement of, or any change after the date of this
Agreement in, any applicable law, rule or regulation of or in the interpretation
or administration thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by Agent or any of the Banks (or any of their respective Eurocurrency
Lending

                                       70

<PAGE>   79

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 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 shall change the basis of taxation of
         payments to any of the Banks (or any of their respective Eurocurrency
         Lending Offices) of the principal of or interest on any Advance or any
         other amounts due under this Agreement in respect thereof (except for
         changes in the rate of tax on the overall net income of any of the
         Banks or any of their respective Eurocurrency Lending Offices imposed
         by the jurisdiction in which such Bank's principal executive office or
         Eurocurrency Lending 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, any of the Banks (or any of their respective Eurocurrency
         Lending Offices) or shall impose on any of the Banks (or any of their
         respective Eurocurrency Lending Offices) or the foreign exchange and
         interbank markets any other condition affecting any Advance;

and the result of any of the foregoing is to increase the costs to any of the
Banks of maintaining any part of the Indebtedness hereunder as a
Eurocurrency-based Advance or to reduce the amount of any sum received or
receivable by any of the Banks under this Agreement in respect of a
Eurocurrency-based Advance, whether with respect to Advances to any of the
Borrowers, then such Bank shall promptly notify Agent, and Agent (or such Bank,
as aforesaid) shall promptly notify the Borrowers of such fact and demand
compensation therefor and, within fifteen (15) days after such notice, the
applicable Borrower agrees to pay to such Bank such additional amount or amounts
as will compensate such Bank or Banks for such increased cost or reduction.
Agent will promptly notify the Borrowers of any event of which it has knowledge
which will entitle Banks to compensation pursuant to this Section, or which will
cause the Borrowers to incur additional liability under Section 12.1 hereof,
provided that Agent shall incur no liability whatsoever to the Banks or the
Borrowers in the event it fails to do so. A certificate of Agent (or such Bank,
if applicable) setting forth in reasonable detail the basis for determining such
additional amount or amounts necessary to compensate such Bank or Banks shall be
conclusively presumed to be correct save for manifest error. Each Bank demanding
compensation under this Section 12.5 shall deliver to the applicable Borrower
such a certificate with, or promptly following, the delivery of the notice and
demand referred to above. 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.

         12.6 Capital Adequacy and Other Increased Costs. In the event that
after the Effective Date the adoption of or any change in any applicable law,
treaty, rule or regulation (whether domestic or foreign) now or hereafter in
effect and whether or not presently applicable to any Bank or Agent, or any
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof, or compliance by any Bank or
Agent with any guideline, request or directive of any such authority (whether or
not having the force of law), including any risk based capital guidelines,
affects or would affect the amount of capital required or expected to be
maintained by such Bank or Agent (or any corporation controlling such Bank or
Agent) and such Bank or Agent, as the case may be, determines that the amount of
such capital is increased by or based upon the existence of such Bank's or
Agent's obligations or Advances hereunder and such increase has the effect of
reducing the rate of return on such Bank's or Agent's (or such controlling
corporation's) capital as a consequence of such obligations or Advances
hereunder to a level below that which such Bank or Agent (or such controlling
corporation) could have achieved but for such circumstances (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank or Agent to be material (collectively, "Increased Costs"), then
Agent or such Bank shall notify the Borrowers, and thereafter the applicable
Borrower 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; notwithstanding the forgoing, however, the
Borrowers shall not be required to pay any increased costs under this Section
12.6 and Sections 12.5 or 3.4(c) for any period ending prior to the date that is
180 days prior to the making of a Bank's initial request for such additional
amounts unless the applicable change in law or other event resulting in such
increased costs is effective retroactively to a date more than 180 days prior to
the date of such request, in which case a Bank's request for such additional
amounts relating to the period more than 180 days prior to the making of the
request must be given not more than 180 days after such Bank becomes aware of
the applicable change in law or other event resulting in such increased costs. 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 Borrowers, reasonably promptly after becoming
aware of any event described in this Section 12.6 and shall be conclusive,
absent manifest error in computation.

         12.7 Substitution of Banks. If (a) the obligation of any Bank to make
Eurocurrency-based Advances has been suspended pursuant to Section 12.3 or 12.4
or (b) any Bank has demanded compensation under Section 3.4(c), 12.5 or 12.6 or
has defaulted in its obligation to make Advances under Article 2 (in each case,
an "Affected Bank"), then the Borrowers shall have the right (subject to Section
14.8 hereof), with the assistance of the Agent, to seek a substitute Bank or
Banks (which may be one or more of the Banks (the "Purchasing Bank" or
"Purchasing Banks") to purchase the Advances of the Revolving Credit and assume
the commitments (including without limitation its participations in Swing Line
Advances and Letters of Credit) under this Agreement of such Affected Bank. The
Affected Bank shall be obligated to sell its Advances of the Revolving Credit,
and assign its commitments to such Purchasing Bank

                                       72

<PAGE>   81

or Purchasing Banks within fifteen days after receiving notice from Borrowers
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,
Borrowers shall pay to the Affected Bank all fees accrued for its account
hereunder to but excluding the date of such sale, plus, if demanded by the
Affected Bank within ten Business Days after such sale, (i) the amount of any
compensation which would be due to the Affected Bank under Section 12.1 if the
applicable Borrower has prepaid the outstanding Eurocurrency-based Advances of
the Affected Bank on the date of such sale and (ii) any additional compensation
accrued for its account under Sections 3.4(c), 12.5 and 12.6 to but excluding
said date. Upon such sale, the Purchasing Bank or Purchasing Banks shall assume
the Affected Bank's commitment, and the Affected Bank shall be released from its
obligations hereunder to a corresponding extent. If any Purchasing Bank is not
already one of the Banks, the Affected Bank, as assignor, such Purchasing Bank,
as assignee, Borrowers and the Agent, shall enter into an Assignment Agreement
pursuant to Section 14.8 hereof, whereupon such Purchasing Bank 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 Revolving Credit Percentage
equal to its ratable share of the then applicable Revolving Credit Aggregate
Commitment of the Affected Bank. In connection with any assignment pursuant to
this Section 12.7, the Borrowers or the Purchasing Bank shall pay to the Agent
the administrative fee for processing such assignment referred to in Section
14.8.

         12.8 Right of Banks to Fund through Branches and Affiliates. Each Bank
may, if it so elects, fulfill its commitment as to any Advance hereunder by
designating a branch or Affiliate of such Bank to make such Advance; provided
that (a) such Bank shall remain solely responsible for the performances of its
obligations hereunder and (b) no such designation shall result in any material
increased costs to the Borrowers.

13.      AGENT

         13.1 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 any Borrowers. 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 Borrowers under this
Agreement or the other Loan Documents or any other instrument executed pursuant
hereto, and for which Agent is not reimbursed by Borrowers, pro rata according
to such Bank's Percentage, but excluding any such expense resulting from

                                       73

<PAGE>   82

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.

         13.2 Deposit Account with Agent. Each of the Borrowers hereby
authorizes Agent, in Agent's sole discretion, to charge their respective 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.

         13.3 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 Borrowers, or any Subsidiary or Affiliate of the Borrowers, 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 the
Borrowers of the 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 Borrowers), 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.

         13.4 Successor Agent. Agent may resign as such at any time upon at
least 45 days prior notice to Borrowers 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 Borrowers. Such successor agent shall
thereupon

                                       74

<PAGE>   83

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.

         13.5 Agent in its Individual Capacity. Comerica, 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 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 were not
acting as Agent hereunder, and may accept fees and other consideration therefor
without having to account for the same to the Banks.

         13.6 Credit Decisions. Each Bank acknowledges that it has,
independently of Agent and each other Bank and based on the financial statements
of Company and its subsidiaries 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.

         13.7 Agent's Fees. The 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 the Company and Agent dated July 2, 1999, as such
letter may be amended or restated from time to time. The Agent's Fees described
in this Section 13.7 shall not be refundable under any circumstances, except
that if Agent resigns, such Agent's Fees shall be prorated through the effective
date of resignation.

                                       75
<PAGE>   84
         13.8 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 Borrowers, or any of their
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.

         13.9 Indemnification. The Banks agree to indemnify the Agent and its
Affiliates (to the extent not reimbursed by the Borrowers, but without limiting
any obligation of the Borrowers to make such reimbursement), ratably according
to their respective Percentages, from and against any and all claims, damages,
losses, liabilities, costs or expenses of any kind or nature whatsoever
(including, without limitation, fees and disbursements of counsel) which may be
imposed on, incurred by, or asserted against the Agent and its Affiliates in any
way relating to or arising out of this Agreement, any of the other Loan
Documents or the transactions contemplated hereby or any action taken or omitted
by the Agent and its Affiliates under this Agreement or any of the Loan
Documents; provided, however, that no Bank shall be liable for any portion of
such claims, damages, losses, liabilities, costs or expenses resulting from the
Agent's or its Affiliates's gross negligence or willful misconduct. Without
limitation of the foregoing, each Bank agrees to reimburse the Agent and its
Affiliates promptly upon demand for its ratable share of any out-of-pocket
expenses (including, without limitation, fees and expenses of counsel) incurred
by the Agent and its Affiliates in connection with the preparation, execution,
delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement or any of the other
Loan Documents, to the extent that the Agent and its Affiliates is not
reimbursed for such expenses by Borrowers, but without limiting the obligation
of Borrowers 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
Borrowers 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.

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

                                       76

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

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.

         13.12 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.

         13.13  Collateral Matters.

         (a) The Agent is authorized on behalf of all the Banks, without the
necessity of any notice to or further consent from the Banks, from time to time
to take any action with respect to any Collateral or the Collateral Documents
which may be necessary to perfect and maintain a perfected security interest in
and Liens upon the Collateral granted pursuant to the Loan Documents.

         (b) The Banks agree to release, and hereby irrevocably authorize the
Agent to release, any Lien granted to or held by the Agent upon any Collateral
(i) upon termination of the Revolving Credit Aggregate Commitment and payment in
full of all Indebtedness payable under this Agreement and under any other Loan
Document; (ii) constituting property sold or to be sold or disposed of as part
of or in connection with any disposition expressly permitted hereunder; or (iii)
if approved, authorized or ratified in writing by the Majority Banks, or all the
Banks, as the case may be, as provided in Section 14.11. Upon request by the
Agent at any time, the Banks will confirm in writing the Agent's authority to
release particular types or items of Collateral pursuant to this Section

of Borrowers and the Banks and their respective successors and assigns.

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

         (c) Borrowers 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

<PAGE>   89

commercial bank, savings and loan association, insurance company, pension fund,
mutual 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. Borrowers authorize 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 Borrowers
which has been delivered to such Bank pursuant to this Agreement, provided that
such prospective assignee or participant shall have agreed to be bound by the
provisions of Section 14.12 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 I (with appropriate insertions acceptable to Agent)
and shall be subject to the terms and conditions hereof, and to the following
restrictions:

             (i)   each assignment shall be in a minimum amount of the lesser of
                   (x) Five Million Dollars ($5,000,000) or such lesser amount
                   as the Agent may agree and (y) the entire remaining amount of
                   assigning Bank's aggregate interest in the Revolving Credit
                   (and participations in any outstanding Letters of Credit);
                   provided however that, after giving effect to such
                   assignment, in no event shall the entire remaining amount (if
                   any) of assigning Bank's aggregate interest in the Revolving
                   Credit (and participations in any outstanding Letters of
                   Credit) be less than $10,000,000; and

             (ii)  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, except that such
                   assignment fee shall not be required if the assignee is an
                   Affiliate of the assignor.

In connection with any assignment, Borrowers 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

                                       81
<PAGE>   90

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, Borrowers shall 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,
replacement 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 Borrowers. Agent, the Banks and Borrowers acknowledge and agree
that any such new Note(s) shall be given in renewal and replacement of the
surrendered Notes and shall not effect or constitute a novation or discharge of
the Indebtedness evidenced by any surrendered Note, and each such new Note may
contain a provision confirming such agreement. In addition, promptly following
receipt of such Notes, Agent shall prepare and distribute to Borrowers 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 14.8(e) with
                   respect to rights of setoff and the benefits of Section 12
                   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 Borrowers 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 (other than a participant which is an Affiliate
                   of such Bank), except for

                                       82
<PAGE>   91

                   those matters covered by Section 14.11(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 Borrowers, Agent and the other Banks
                   may continue to deal directly with such Bank in connection
                   with such Bank's rights and duties hereunder).

Borrowers agree that each participant shall be deemed to have the right of
setoff under Section 10.6 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 11.4
hereof and shall be entitled to the benefits of Section 12 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 Borrowers, the Agent and the other Banks shall
have any responsibility or obligation with respect thereto, or to any Person to
whom any such participation may be issued. No such participation shall relieve
any issuing Bank of any of its obligations under this Agreement or any of the
other Loan Documents, and all actions hereunder shall be conducted as if no such
participation had been granted.

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

         14.9 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.

         14.10 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.

         14.11 Amendment and Waiver. No amendment or waiver of any provision of
this Agreement or any other Loan Document, nor consent to any departure by
Borrowers 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 Borrowers or any other Persons
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

                                       83

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 definitions of "Percentage", or of "Majority Banks"
or this Section 14.11; provided further, that no amendment, waiver or consent
shall, unless in writing signed by the Swing Line Bank do any of the following:
(x) reduce the principal of, or interest on, the Swing Line Note or (y) postpone
any date fixed for any payment of principal of, or interest on, the Swing Line
Note; and 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.

         14.12 Confidentiality. Each Bank agrees that it will not disclose
without the prior consent of Borrowers (other than to its employees, another
Bank or to its auditors or counsel) any information with respect to Borrowers
which is furnished pursuant to this Agreement or any of the other Loan
Documents; 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 Borrowers, (b) as
may be required or appropriate in any report, statement or testimony submitted
to, or in respect to any inquiry, by, any municipal, state or federal regulatory

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

permitted transferee or assignee or to any approved participant of, or with
respect to, the Notes, as aforesaid, provided that such financial institution,
transferee or assignee agrees to be bound by the provisions of this Section
14.12.

         14.13 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 (x) two executed copies of (i) Internal Revenue Service Form 1001 (or any
successor form) 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 or (ii) Internal Revenue
Service Form 4224 (or any successor form) evidencing that the income to be

<PAGE>   93

States or (y) other evidence satisfactory to the Agent and Borrowers 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.

         14.14 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 Borrowers agree to pay the same, together with
any interest or penalties thereon arising from the Borrowers' act or omission,
and agrees to hold the Agent and the Banks harmless with respect thereto.
Notwithstanding the foregoing, nothing contained in this Section 14.14 shall
affect or reduce the rights of any Bank or the Agent under Section 12.6 hereof.

         14.15 WAIVER OF JURY TRIAL. EACH OF THE BANKS, THE AGENT AND THE
BORROWERS 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 BORROWERS SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM OR OTHERWISE,
ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY OTHER ACTION IN
WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE PROVISIONS SHALL NOT
BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY THE BANKS, AND
THE AGENT, OR BORROWERS EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

         14.16 Interest. It is the intention of the parties hereto that each
Bank and the Agent shall conform to usury laws applicable to them, if any.
Accordingly, if the transactions with any Bank or Agent contemplated hereby
would be usurious under such applicable laws, then, notwithstanding anything to
the contrary in the Notes or Loan Documents payable to such Bank, this Agreement
or any other agreement entered into in connection with or as security for or
guaranteeing this Agreement or the Indebtedness, it is agreed as follows: (i)
the aggregate of all consideration which constitutes interest under applicable
law that is contracted for, taken, reserved, charged or received by such Bank
under the Notes payable to such Bank, this

                                       85
<PAGE>   94

Agreement, the Loan Documents or under any other agreement entered into in
connection with or as security for or guaranteeing this Agreement or such Notes
or Loan Documents shall under no circumstances exceed the maximum amount allowed
by such applicable law, and any excess shall be credited automatically, if
theretofore paid, on the principal amount of the Indebtedness owed to such Bank
or, if no Indebtedness to such Bank is outstanding, shall be refunded to
Borrowers by such Bank, and (ii) in the event that the maturity of any such Note
or other Indebtedness is accelerated or in the event of any required or
permitted prepayment, then such consideration that constitutes interest under
law applicable to such Bank may never include more than the maximum amount
allowed by such applicable law and excess interest, if any, to such Bank shall
be canceled automatically as of the date of such acceleration or prepayment and,
if theretofore paid, shall be credited by such Bank on the principal amount of
the Indebtedness owed to such Bank by the Borrowers or, if no Indebtedness to
such Bank is then outstanding, shall be refunded by such Bank to the Borrowers.

         14.17 Complete Agreement; Conflicts. This Agreement, the Notes, any
Requests for Revolving Credit Advance and Requests for Swing Line Advance
hereunder, and the other 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.

         14.18 Severability. In case any one or more of the obligations of the
Borrowers or any other Person 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 the Borrowers, or such Person 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 the Borrowers and such Person under this Agreement, the Notes or
any of the other Loan Documents in any other jurisdiction.

         14.19 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.

         14.20 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.

         14.21 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.

         14.22 Reliance on and Survival of Various Provisions. All terms,
covenants, agreements, representations and warranties of the Borrowers 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 the Borrowers or any such party 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
Borrowers set forth in Sections 12.5 and 12.6 hereof (together with any other
indemnities of Borrowers or any other Person contained elsewhere in this
Agreement or in any of the other Loan Documents) and of Banks set forth in
Section 13.9 hereof shall survive the repayment in full of the Indebtedness and
the termination of the Revolving Credit Aggregate Commitment.

         14.23 Merger Agreement; Effect. The Merger Agreement provides for the
merger of Newco with and into Smartflex as the surviving corporation, in
accordance with the Delaware General Corporation Law ("DGCL"). Upon and
following the Merger Date, and as provided in Section 2.03 of the Merger
Agreement and Section 259 of the DGCL, (i) all obligations of Newco under this
Agreement and the other Loan Documents to which Newco is a party shall be and
become the direct obligations of Smartflex without further action, assignment or
assumption by Newco, Smartflex or any other Person, (ii) all references to Newco
in this Agreement and the other Loan Documents shall be deemed to be references
to Smartflex, and (iii) the Borrowers (including Smartflex) will execute and
deliver new Revolving Credit Notes naming Smartflex as a maker.

         14.24 Joint and Several Liability of Borrowers and Related Matters.

         (a) Each of the Borrowers acknowledges and agrees that it is the intent
of the parties that each such Borrower be primarily liable for the obligations
as a joint and several obligor (except as set forth in sub-section (g), below).
It is the intention of the parties that with respect to liability of any
Borrower hereunder arising solely by reason of its being jointly and severally
liable for Advances and other extensions of credit taken by the other Borrowers,
the obligations of such Borrower shall be absolute, unconditional and
irrevocable irrespective of:

              (i) any lack of validity, legality or enforceability of this
         Agreement or any Note as to any Borrower, as the case may be;

              (ii) the failure of any Bank or any holder of any Note:

                   (A) to enforce any right or remedy against any Borrower, as
              the case may be, or any other Person (including any guarantor)
              under the provisions of this Agreement, such Note, or otherwise,
              or

                   (B) to exercise any right or remedy against any guarantor of,
              or collateral securing, any obligations;

                                       87
<PAGE>   96

              (iii) any change in the time, manner or place of payment of, or in
         any other term of, all or any of the Indebtedness, or any other
         extension, compromise or renewal of any Indebtedness;

              (iv) any reduction, limitation, impairment or termination of any
         Indebtedness with respect to any Borrower, as the case may be, for any
         reason, including any claim of waiver, release, surrender, alteration
         or compromise, and shall not be subject to (and each of the Borrowers
         hereby waives any right to or claim of) any defense (other than the
         defense of payment in full of the Indebtedness) or setoff,
         counterclaim, recoupment or termination whatsoever by reason of the
         invalidity, illegality, nongenuineness, irregularity, compromise,
         unenforceability of, or any other event or occurrence affecting, any
         Indebtedness with respect to any Borrower, as the case may be;

              (v) any addition, exchange, release, surrender or nonperfection of
         any collateral, or any amendment to or waiver or release or addition
         of, or consent to departure from, any guaranty, held by any Bank or any
         holder of the Notes securing any of the Indebtedness; or

              (vi) any other circumstance which might otherwise constitute a
         defense (other than the defense of payment in full of the Indebtedness)
         available to, or a legal or equitable discharge of, any Borrower, as
         the case may be, any surety or any guarantor.

         (b) Each of the Borrowers agrees that its joint and several liability
hereunder shall continue to be effective or be reinstated, as the case may be,
if at any time any payment (in whole or in part) of any of the Indebtedness is
rescinded or must be restored by any Bank or any holder of any Note, upon the
insolvency, bankruptcy or reorganization of any Borrower, as the case may be, as
though such payment had not been made.

         (c) Each of the Borrowers hereby expressly waives: (i) notice of the
Banks' acceptance of this Agreement; (ii) notice of the existence or creation or
non payment of all or any of the Indebtedness other than notices expressly
provided for in this Agreement; (iii) presentment, demand, notice of dishonor,
protest, and all other notices whatsoever other than notices expressly provided
for in this Agreement; and (iv) all diligence in collection or protection of or
realization upon the Indebtedness or any part thereof, any obligation hereunder,
or any security for or guaranty of any of the foregoing, subject, however, in
the case of Collateral in the possession of Agent or a Bank to such Person's
duty to use reasonable care in the custody and preservation of such Collateral.

         (d) No delay on any of the Banks' part in the exercise of any right or
remedy shall operate as a waiver thereof, and no single or partial exercise by
any of the Banks of any right or remedy shall preclude other or further exercise
thereof or the exercise of any other right or remedy. No action of any of the
Banks permitted hereunder shall in any way affect or impair any such Banks'
rights or any Borrower's Indebtedness under this Agreement.

                                       88
<PAGE>   97

         (e) Each of the Borrowers hereby represents and warrants to each of the
Banks that it now has and will continue to have independent means of obtaining
information concerning the Borrowers' affairs, financial condition and business.
Banks shall not have any duty or responsibility to provide any Borrower with any
credit or other information concerning such Borrower's affairs, financial
condition or business which may come into the Banks' possession.

         (f) Each of the Borrowers represents and warrants (i) that the business
operations of the Borrowers are interrelated and complement one another, and
such entities have a common business purpose, with intercompany bookkeeping and
accounting adjustments used to separate their respective properties,
liabilities, and transactions; and (ii) that, to permit their uninterrupted and
continuous operations, such entities now require and will from time to time
hereafter require funds and credit accommodations for general business purposes
and that (iii) the proceeds of advances under the Revolving Credit, the Swing
Line and any other credit facilities extended hereunder will directly or
indirectly benefit the Borrowers hereunder, severally and jointly, regardless of
which Borrower requests or receives part or all of the proceeds of such
Advances.

         (g) Notwithstanding anything to the contrary contained herein, it is
the intention of the Borrowers, Agent and the Banks that the amount of the
respective Borrowers' obligations hereunder shall be in, but not in excess of,
the maximum amount thereof not subject to avoidance or recovery by operation of
applicable law governing bankruptcy, reorganization, arrangement, adjustment of
debts, relief of debtors, dissolution, insolvency, fraudulent transfers or
conveyances or other similar laws (collectively, "Applicable Insolvency Laws").
To that end, but only in the event and to the extent that the Borrowers'
respective obligations hereunder or any payment made pursuant thereto would, but
for the operation of the foregoing proviso, be subject to avoidance or recovery
under Applicable Insolvency Laws, the amount of the Borrowers' respective
obligations hereunder shall be limited to the largest amount which, after giving
effect thereto, would not, under Applicable Insolvency Laws, render the
Borrowers' respective obligations hereunder unenforceable or avoidable or
subject to recovery under Applicable Insolvency Laws. To the extent any payment
actually made hereunder exceeds the limitation contained in this Section
14.24(g), then the amount of such excess shall, from and after the time of
payment by the Borrowers (or any of them), be reimbursed by the Banks upon
demand by such Borrowers. The foregoing proviso is intended solely to preserve
the rights of the Agent and the Banks hereunder against the Borrowers to the
maximum extent permitted by Applicable Insolvency Laws and neither any Borrower
nor any Guarantor nor any other Person shall have any right or claim under this
Section 14.24(g) that would not otherwise be available under Applicable
Insolvency Laws.

       14.25 Complete Agreement; Amendment and Restatement. This Agreement, the
Notes, any Requests for Advance or Letters of Credit hereunder, the other Loan
Documents and any agreements, certificates, or other documents given to secure
the Indebtedness, contain the entire agreement of the parties hereto, and none
of the parties hereto shall be bound by anything not expressed in writing. This
Agreement constitutes an amendment to and restatement in its entirety of the
Prior Credit Agreement, which Prior Credit Agreement is fully superseded and
amended and restated in its entirety hereby; provided, however, that the
Indebtedness governed by the

                                       89
<PAGE>   98

Prior Credit Agreement shall remain outstanding and in full force and effect and
provided further that this Agreement does not constitute a novation of such
Indebtedness.

                        BORROWER OR GUARANTOR, AS MAKER

                                                          ________________, 1999

         ON DEMAND, FOR VALUE RECEIVED, the undersigned ("MAKER") promises to
pay to the order of Saturn Electronics & Engineering, Inc. from which it has
received advances of credit ("Holder") at such place as shall be designated from
time to time by each such Holder to Maker, in lawful money of the United States
of America or in such other currencies applicable to any particular advance made
hereunder (each an "Advance" and, collectively, the "Advances") which may, from
time to time, be outstanding hereunder, such sum as may from time to time have
been advanced by Holder to Maker and then be outstanding hereunder, together
with interest thereon as hereinafter set forth.

         Each Advance shall bear interest at Holder's average cost of Borrowing
as certified by Holder from time to time.

         Interest on the unpaid balance of all Advances shall be payable in
immediately available funds quarterly commencing on                   , 1999 and
on the first day of each calendar quarter thereafter. Interest accruing shall be
computed on the basis of a 365 day year and assessed for the actual number of
days elapsed.

         This Note is a note under which advances, repayments and readvances may
be made from time to time.

         Upon the occurrence and during the continuance of an Event of Default,
as defined in that certain Saturn Electronics & Engineering, Inc. Credit
Agreement dated as of August 24, 1999 (as amended, or otherwise modified from
time to time, the "Credit Agreement") by and among Saturn Electronics &
Engineering, Inc., a Michigan corporation ("Company"), Saturn Manufacturing,
Co., an Ohio corporation ("Manufacturing"), SSI Acquisition Corp., a Delaware
corporation ("SSI"), certain financial institutions from time to time signatory
thereto (the "Banks") and Comerica Bank, as Agent for the Banks (the "Agent"),
and following receipt of notice from the Agent, (A) no payments may be made of
the principal of or interest on this Note, and (B) this Note shall be fully
subordinated in all respects to the Indebtedness (as defined in the Credit
Agreement).

         As used herein, "Senior Creditors" shall refer to the Banks and "Senior
Indebtedness" shall refer to the Indebtedness under the Credit Agreement.

         During the period when payments of interest hereon are not permitted by
the second

<PAGE>   133

preceding paragraph, interest shall accrue and be added to principal on each
interest payment date.

         Maker agrees, and Holder by accepting this Note agrees, that: (A) the
obligations evidenced by this Note are subordinated in right of payment, to the
prior payment in full of all the Senior Indebtedness; the subordination is for
the benefit of the Senior Creditors, and each Senior Creditor whether now
outstanding or hereafter created, incurred, assumed or guaranteed shall be
deemed to have acquired Indebtedness in reliance upon the covenants and
provisions contained in this Note; (B) if Maker is prohibited by the terms of
this Note from making any payment of principal, interest or any other sum under
or in respect of this Note when due, and therefore the Maker shall fail to pay
when due any such sum, such failure shall not constitute a default or event of
default under and in respect of this Note (provided that interest shall continue
to accrue as provided herein and be added to principal as herein set forth); and
(C) no revision to any provision of this Note applicable or relevant to the
subordination of this Note to the Senior Indebtedness shall be made or become
effective until approved in writing by the Agent.

         Upon any distribution (whether cash, securities or other property, by
setoff or otherwise) to creditors of Maker in a liquidation or dissolution of
Maker or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to Maker or its property: (A) Senior Creditors shall be
entitled to payment in full of all obligations with respect to the Senior
Indebtedness (including interest after the commencement of any such proceeding
at the rates specified for the applicable Indebtedness) to the date of payment
of the Indebtedness before Holder shall be entitled to receive any payment of
any obligations with respect to this Note; and (B) until all obligations with
respect to the Senior Indebtedness are paid in full, any distribution to which
Holder would be entitled shall be made to Senior Creditors as their interests
may appear.

         No right of any Senior Creditor to enforce the subordination of the
indebtedness evidenced by this Note shall be impaired by any act or failure to
act by the Maker or by its failure to comply with the terms and conditions of
this Note.

         This Note shall be interpreted and the rights of the parties hereunder
shall be determined under the laws of, and enforceable in, the State of
Michigan.

         Maker hereby waives presentment for payment, demand, protest and notice
of dishonor and nonpayment of this Note and agrees that no obligation hereunder
shall be discharged by reason of any extension, indulgence, release, or
forbearance granted by any holder of this Note to any party now or hereafter
liable hereon or any present or subsequent owner of any property, real or
personal, which is now or hereafter security for this Note.

         Terms not defined herein shall have the meanings set forth in the
Credit Agreement.

undivided interest in each of Assignor's rights and obligations under the Credit
Agreement and the other Loan Documents such that, after giving effect to the
foregoing assignment and assumption, [and the other assignments by Assignor to
            on the date hereof,] the Assignee's interest, and the Assignor's
interest remaining (if any), in the Revolving Credit (and participations in any
outstanding Letters of Credit) shall be as set forth on the attached schedule.

         The Assignor hereby instructs the Agent to make all payments from and
including the Effective Date hereof in respect of the interest assigned hereby,
directly to the Assignee. The Assignor and the Assignee agree that all interest
and fees accrued up to, but not including, the Effective Date of the assignment
and delegation being made hereby are the property of the Assignor, and not the
Assignee. The Assignee agrees that, upon receipt of any such interest or fees
accrued up to the Effective Date, the Assignee will promptly remit the same to
the Assignor.

         The Assignee hereby confirms that it has received a copy of the Credit
Agreement and the exhibits and schedules referred to therein, and all other Loan
Documents which it considers necessary, together with copies of the other
documents which were required to be delivered under the Credit Agreement as a
condition to the making of the loans thereunder. The Assignee acknowledges and
agrees that it: (a) is legally authorized to enter into this Assignment
Agreement; (b) has made and will continue to make such inquiries and has taken
and will take such care on its own behalf as would have

been the case had its Percentages been granted and its loans been made directly
by such Assignee to Borrowers without the intervention of the Agent, the
Assignor or any other Bank; and (c) has made and will continue to make,
independently and without reliance upon the Agent, the Assignor or any other
Bank, and based on such documents and information as it has deemed appropriate,
its own credit analysis and decisions relating to the Credit Agreement. The
Assignee further acknowledges and agrees that neither the Agent, nor the
Assignor has made any representations or warranties about the creditworthiness
of any Borrower or any other party to the Credit Agreement or any other of the
Loan Documents, or with respect to the legality, validity, sufficiency or
enforceability of the Credit Agreement, or any other of the Loan Documents. This
assignment shall be made without recourse to or warranty by the Assignor, except
as set forth herein.

         Assignee represents and warrants that it is a Person to which
assignments are permitted pursuant to Section 14.8(c) of the Credit Agreement.

         Assignor represents and warrants, as of the Effective Date, that it is
the legal and beneficial owner of the interest being assigned and delegated by
it hereunder and that such interest is free and clear of any pledge, encumbrance
or other adverse claim or interest created by Assignor.

         Except as otherwise provided in the Credit Agreement, effective as of
the Effective Date:

         (a)      the Assignee: (i) shall be deemed automatically to have become
                  a party to the Credit Agreement and the other Loan Documents,
                  to have assumed all of the Assignor's obligations thereunder
                  to the extent of the Assignee's Percentage referred to in the
                  second paragraph of this Assignment Agreement, and to have all
                  the rights and obligations of a party to the Credit Agreement
                  and the other Loan Documents, as if it were an original
                  signatory thereto to the extent specified in the second
                  paragraph hereof; and (ii) agrees to be bound by the terms and
                  conditions set forth in the Credit Agreement and the other
                  Loan Documents as if it were an original signatory thereto;
                  and

         (b)      the Assignor's obligations under the Credit Agreement and the
                  other Loan Documents shall be reduced by the percentage
                  assigned to Assignee referred to in the second paragraph of
                  this Assignment Agreement.

         As used herein, the term "Effective Date" means the date on which all
of the following have occurred or have been completed, as reasonably determined
by the Agent:

         (1)      the delivery to the Agent of an original of this Assignment
                  Agreement executed by the Assignor and the Assignee;

         (2)      the payment to the Agent, of all accrued fees, expenses and
                  other items for which reimbursement is then owing under the
                  Credit Agreement;

                                        2

<PAGE>   139

         (3)      the payment to the Agent of the $3,500 processing fee referred
                  to in Section 14.8(d) (ii) of the Credit Agreement; and

         (4)      all other restrictions and items noted in Sections 14.8(c) and
                  (d) of the Credit Agreement have been completed.

         Following the execution and delivery of this Assignment Agreement by
the Assignor and Assignee to the Agent and the Agent shall notify the Assignor
and the Assignee, along with the Borrowers, of the Effective Date.

         On the Effective Date the Assignee shall pay to the Assignor the amount
agreed upon with respect to the outstanding principal amount of the outstanding
Advances of the Revolving Credit owed to Assignor by the Borrowers under the
Credit Agreement in respect of the interest being assigned hereby.

         The Assignee hereby advises each of you that an administrative detail
with respect to the assigned loans has been filed with the Agent:

         The Assignee has delivered to the Agent (or is delivering to the Agent
concurrently herewith) the tax forms referred to in Section 14.13 of the Credit
Agreement, and other forms reasonably requested by the Agent. The Assignor has
delivered to the Agent (or is delivering to Agent concurrently herewith), the
original of each Note held by the Assignor under the Credit Agreement.

         Please evidence your consent to and acceptance of the proposed
assignment and delegation set forth herein by signing and returning counterparts
hereof to the Assignor and the Assignee.
