                           (until paid), bear interest at its Applicable
                           Interest Rate.

                  (b)      Each Revolving Credit Lender shall maintain in

                           appropriate lending office of such Revolving Credit
                           Lender resulting from each Revolving Credit Advance
                           made by such lending office of such Revolving Credit
                           Lender from time to time, including the amounts of
                           principal and interest payable thereon and paid to
                           such Revolving Credit Lender from time to time under
                           this Agreement.

                  (c)      The Agent shall maintain the Register pursuant to
                           Section 13.8(g), and a subaccount therein for each

                           hereunder, the type thereof and each
                           Eurodollar-Interest Period applicable to any
                           Eurodollar-based Advance, (ii) the amount of any
                           principal or interest due and payable or to become
                           due and payable from Borrower to each Revolving
                           Credit Lender hereunder in respect of the Revolving
                           Credit Advances and (iii) both the amount of any sum

                           Revolving Credit Lender's share thereof.

                           to paragraph (c) of this Section 2.2 shall, absent
                           manifest error, to the extent permitted by applicable
                           law, be prima facie evidence of the existence and
                           amounts of the obligations of Borrower therein
                           recorded; provided, however, that the failure of any
                           Revolving Credit Lender or the Agent to maintain the
                           Register or any account, as applicable, or any error
                           therein, shall not in any manner affect the
                           obligation of Borrower to repay the Revolving Credit
                           Advances (and all other amounts owing with respect
                           thereto) made to Borrower by the Revolving Credit
                           Lenders in accordance with the terms of this
                           Agreement.

                  (e)      Borrower agrees that, upon written request to the
                           Agent by any Revolving Credit Lender, Borrower will
                           execute and deliver, to such Revolving Credit Lender,
                           at Borrower's own expense, a Revolving Credit Note
                           evidencing the outstanding Revolving Credit Advances
                           owing to such Revolving Credit Lender.

         2.3 Requests for and Refundings and Conversions of Advances. Borrower
may request an Advance of the Revolving Credit, a refund of any Revolving Credit
Advance in the same type of Advance or to convert any Revolving Credit Advance
to any other type of Revolving Credit Advance only by delivery to Agent of a
Request for Revolving Credit Advance executed by an Authorized Signer for the
Borrower, subject to the following:

                  (a)      each such Request for Revolving Credit Advance shall
                           set forth the information required on the Request for

                                    an outstanding Revolving Credit Advance),
                                    which must be a Business Day;

                           (ii)     whether such Advance is a new Revolving

                                    of an outstanding Revolving Credit Advance;
                                    and

                           (iii)    whether such Revolving Credit Advance is to
                                    be a Prime-based Advance or a
                                    Eurodollar-based Advance, and, except in the
                                    case of a Prime-based Advance, the first
                                    Eurodollar-Interest Period applicable
                                    thereto, provided, however, that the initial
                                    Revolving Credit Advance made under this
                                    Agreement shall be a Prime-based Advance,
                                    which may then be converted into a
                                    Eurodollar-based Advance in compliance with
                                    this Agreement.

                  (b)      each such Request for Revolving Credit Advance shall
                           be delivered to Agent by 12:00 p.m. (Detroit time)

                           the Revolving Credit Advance, except in the case of a
                           Prime-based Advance, for which the Request for
                           Revolving Credit Advance must be delivered by 12:00
                           p.m. (Detroit time) on the proposed date for such
                           Revolving Credit Advance;

                  (c)      on the proposed date of such Revolving Credit
                           Advance, the sum of (x) the aggregate principal

                           Line Advances outstanding on such date (including,
                           without duplication) the Advances that are deemed to
                           be disbursed by Agent under Section 3.6(a) hereof in
                           respect of Borrower's Reimbursement Obligations
                           hereunder), plus (y) the Letter of Credit Obligations
                           as of such date, in each case after giving effect to
                           all outstanding requests for Revolving Credit
                           Advances and Swing Line Advances and for the issuance
                           of any Letters of Credit, shall not exceed the
                           Revolving Credit Aggregate Commitment;

                  (d)      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 $1,000,000 or the remainder available
                           under the Revolving Credit Aggregate Commitment if
                           less than $1,000,000;

                  (e)      in the case of a Eurodollar-based Advance, the
                           principal amount of such Advance, plus the amount of
                           any other outstanding Revolving Credit Advance to be
                           then combined therewith having the same
                           Eurodollar-Interest Period, if any, shall be at least
                           $2,000,000 (or a larger integral multiple of
                           $250,000) or the remainder available under the
                           Revolving Credit Aggregate Commitment if less than
                           $2,000,000 and at any one time there shall not be in
                           effect more than four (4) different
                           Eurodollar-Interest Periods;

                  (f)      a Request for Revolving Credit Advance, once
                           delivered to Agent, shall not be revocable by
                           Borrower and shall constitute a certification by
                           Borrower as of the date thereof that:

                           (i)      all conditions to the making of Revolving
                                    Credit Advances set forth in this Agreement
                                    have been satisfied, and shall remain
                                    satisfied to the date of such Revolving
                                    Credit Advance (both before and immediately
                                    after giving effect to such Revolving Credit
                                    Advance);

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

                           (iii)    the representations and warranties of the
                                    Borrowers contained in this Agreement and
                                    the other Loan Documents are true and
                                    correct in all material respects and shall
                                    be true and correct in all material respects
                                    as of the date of the making of such
                                    Revolving Credit Advance (both before and
                                    immediately after giving effect to such
                                    Revolving Credit Advance), other than any
                                    representation or warranty that expressly
                                    speaks only as of a different date;

Agent, acting on behalf of the Revolving Credit Lenders, may also, at its
option, lend under this Section 2.3 upon the telephone or email request of an
Authorized Signer of the Borrower to make such requests and, in the event Agent,
acting on behalf of the Revolving Credit Lenders, makes any such Advance upon a
telephone or email request, an Authorized Signer shall fax or deliver by
electronic file to Agent, on the same day as such telephone or email request, an
executed Request for Revolving Credit Advance. Borrower hereby authorizes Agent
to disburse Advances under this Section 2.3 pursuant to the telephone or email
instructions of any person purporting to be an Authorized Signer.
Notwithstanding the foregoing, Borrower acknowledges that Borrower shall bear
all risk of loss resulting from disbursements made upon any telephone or email
request. Each telephone or email request for an Advance from an Authorized
Signer for the Borrower 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
Borrower under Section 2.3 hereof, Agent shall promptly notify each Revolving
Credit Lender by wire, telex or telephone (confirmed by wire, telecopy or telex)
of the amount of such Advance being requested and the date such Revolving Credit
Advance is to be made by each Revolving Credit Lender in an amount equal to its
Revolving Credit Percentage of such Advance. Unless such Revolving Credit
Lender's commitment to make Revolving Credit Advances hereunder shall have been
suspended or terminated in accordance with this Agreement, each such Revolving
Credit Lender shall make available the amount of its Revolving Credit Percentage
of each Revolving Credit Advance in immediately available funds to Agent, as
follows:

                  (i)      for Prime-based Advances, at the office of Agent
                           located at One Detroit Center, Detroit, Michigan
                           48226, not later than 1:00 p.m. (Detroit time) on the
                           date of such Advance; and

                  (ii)     for Eurodollar-based Advances, at the Agent's
                           Correspondent for the account of the Eurodollar
                           Lending Office of the Agent, not later than 12:00
                           p.m. (the time of the Agent's Correspondent) on the
                           date of such Advance.

         (b) Subject to submission of an executed Request for Revolving Credit
Advance by Borrower without exceptions noted in the compliance certification
therein, Agent shall make available to Borrower the aggregate of the amounts so
received by it from the Revolving Credit Lenders in like funds and currencies:

                  (i)      for Prime-based Advances, not later than 4:00 p.m.
                           (Detroit time) on the date of such Revolving Credit
                           Advance, by credit to an account of Borrower
                           maintained with Agent or to such other account or
                           third party as Borrower may reasonably direct in
                           writing in compliance with Section 7.4(e), provided
                           such direction is timely given; and

                  (ii)     for Eurodollar-based Advances, not later than 4:00
                           p.m. (the time of the Agent's Correspondent) on the
                           date of such Revolving Credit Advance, by credit to
                           an account of Borrower maintained with Agent's
                           Correspondent or to such other account or third party
                           as Borrower may direct in compliance with Section
                           7.4(e), provided such direction is timely given.

         (c) Agent shall deliver the documents and papers received by it for the
account of each Revolving Credit Lender to such Revolving Credit Lender. Unless
Agent shall have been notified by any Revolving Credit Lender at least two (2)
Business Days prior to the date of any proposed Revolving Credit Advance that
such Revolving Credit Lender does not intend to make available to Agent such
Revolving Credit Lender's Percentage of such Advance, Agent may assume that such
Revolving Credit Lender has made such amount available to Agent on such date, as
aforesaid. Agent may, but shall not be obligated to, make available to Borrower

                                       18
<PAGE>

the amount of such payment in reliance on such assumption. If such amount is not
in fact made available to Agent by such Revolving Credit Lender, as aforesaid,
Agent shall be entitled to recover such amount on demand from such Revolving
Credit Lender. If such Revolving Credit Lender does not pay such amount
forthwith upon Agent's demand therefor and the Agent has in fact made a
corresponding amount available to Borrower, the Agent shall promptly notify
Borrower and Borrower shall pay such amount to Agent, if such notice is
delivered to Borrower prior to 1:00 p.m. (Detroit time) on a Business Day, on
the day such notice is received, and otherwise on the next Business Day, and
such amount paid by Borrower shall be applied as a prepayment of the Revolving
Credit (without any corresponding reduction in the Revolving Credit Aggregate
Commitment), reimbursing Agent for having funded said amounts on behalf of such
Revolving Credit Lender. The Borrower shall retain its claim against such
Revolving Credit Lender with respect to the amounts repaid by it to Agent and,
if such Revolving Credit Lender subsequently makes such amounts available to
Agent, Agent shall promptly make such amounts available to the Borrower as a
Revolving Credit Advance. Agent shall also be entitled to recover from such
Revolving Credit Lender or Borrower, 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 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 Lender, for the
                           first two (2) Business Days such amount remains
                           unpaid, the Federal Funds Effective Rate, and
                           thereafter, at the rate of interest then applicable
                           to such Revolving Credit Advances; and

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

Until such Revolving Credit Lender has paid Agent such amount, such Revolving
Credit Lender shall have no interest in or rights with respect to such Advance
for any purpose whatsoever. The obligation of any Revolving Credit Lender to
make any Revolving Credit Advance hereunder shall not be affected by the failure
of any other Revolving Credit Lender to make any Advance hereunder, and no
Revolving Credit Lender shall have any liability to Borrower or any of its
Subsidiaries, the Agent, any other Revolving Credit Lender, or any other party
for another Revolving Credit Lender's failure to make any loan or Advance
hereunder.

         2.5 Interest Payments; Default Interest. (a) (a) Interest on the unpaid
balance of all Prime-based Advances of the Revolving Credit and the Swing Line
from time to time outstanding shall accrue from the date of such Advance to the
date repaid, at a per annum interest rate equal to the Prime-based Rate, and
shall be payable in immediately available funds commencing on October 1, 2007,
and on the first day of each calendar quarter thereafter. Whenever any payment
under this Section 2.5(a) shall become due on a day which is not a Business Day,
the date for payment thereof shall be extended to the next Business Day.
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
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.

         (b) Interest on each Eurodollar-based Advance of the Revolving Credit
shall accrue at its Eurodollar-based Rate and shall be payable in immediately
available funds on the last day of the Eurodollar-Interest Period applicable
thereto (and, if any Eurodollar-Interest Period shall exceed three months, then
on the last Business Day of the third month of such Eurodollar-Interest Period,
and at three month intervals thereafter). Interest accruing at the
Eurodollar-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
Eurodollar-Interest Period applicable thereto to but not including the last day
thereof.

         (c) 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.

         (d) Notwithstanding anything to the contrary in the preceding sections,
all accrued and unpaid interest on any Revolving Credit Advance refunded or
converted pursuant to Section 2.3 hereof and any Swing Line Advance refunded
pursuant to Section 2.12(e) hereof, shall be due and payable in full on the date
such Advance is refunded or converted.

         (e) In the case of any Event of Default under Section 9.1(i),
immediately upon the occurrence thereof, and in the case of any other Event of
Default, immediately upon receipt by Agent of notice from the Majority Lenders,
interest shall be payable on demand on all Revolving Credit Advances and Swing
Line Advances from time to time outstanding at a per annum rate equal to the
Applicable Interest Rate in respect of each such Advance plus, in the case of
Eurodollar-based Advances and Quoted Rate Advances, two percent (2%) for the
remainder of the then existing Interest Period, if any, and at all other such
times, and for all Prime-based Advances from time to time outstanding, at a per
annum rate equal to the Prime-based Rate plus two percent (2%).

2.6      Optional Prepayments.

         (a) (i) The Borrower may prepay all or part of the outstanding
principal of any Prime-based Advance(s) of the Revolving Credit at any time,
provided that, after giving effect to any partial prepayment, the aggregate
balance of Prime-based Advance(s) of the Revolving Credit remaining outstanding
shall be at least One Million Dollars ($1,000,000), and (ii) the Borrower may
prepay all or part of the outstanding principal of any Eurodollar-based Advance
of the Revolving Credit at any time (subject to not less than five (5) Business
Day's notice to Agent).

         (b) (i) The Borrower may prepay all or part of the outstanding
principal of any Swing Line Advance carried at the Prime-based Rate at any time,
provided that after giving effect to any partial prepayment, the aggregate
balance of such Prime-based Swing Line Advances remaining outstanding shall be
at least Zero Dollars ($0.00) and (ii) the Borrower may prepay all or part of
the outstanding principal of any Swing Line Advance carried at the Quoted Rate
at any time (subject to not less than one (1) day's notice to the Swing Line
Lender) provided that after giving effect to any partial prepayment, the
aggregate balance of such Quoted Rate Swing Line Advances remaining outstanding
shall be at least Zero Dollars ($0.00).

         (c) Any prepayment of a Prime-based Advance made in accordance with
this Section shall be without premium or penalty and any prepayment of any other
type of Advance shall be subject to the provisions of Section 11.1 hereof, but
otherwise without premium or penalty.

         2.7 Prime-based Advance in Absence of Election or Upon Default. If, (a)
as to any outstanding Eurodollar-based Advance of the Revolving Credit or any
outstanding Quoted Rate Advance of the Swing Line, Agent has not received
payment of all outstanding principal and accrued interest on the last day of the
Interest Period applicable thereto, or does not receive a timely Request for
Advance meeting the requirements of Section 2.3 or 2.12 hereof with respect to
the refunding or conversion of such Advance, or (b) subject to Section 2.5(d)
hereof, if on the last day of the applicable Interest Period a Default or an
Event of Default shall have occurred and be continuing, then, on the last day of
the applicable Interest Period the principal amount of any Eurodollar-based
Advance, which has not been prepaid shall, absent a contrary election of the
Majority Lenders, be converted automatically to a Prime-based Advance and the
Agent shall thereafter promptly notify Borrower of said action.

         2.8 Revolving Credit Facility Fee. From the Effective Date to the
Revolving Credit Maturity Date, Borrower shall pay to the Agent for distribution
to the Revolving Credit Lenders pro-rata in accordance with their respective
Percentages, a Revolving Credit Facility Fee quarterly in arrears commencing
October 1, 2007 (in respect of the prior quarter or any portion thereof), and on
the first day of each calendar quarter thereafter. Whenever any payment of the
Revolving Credit Facility Fee shall be due on a day which is not a Business Day,
the date for payment thereof shall be extended to the next Business Day. The
Revolving Credit Facility Fee payable to each Revolving Credit Lender shall be

                                       20
<PAGE>

determined by multiplying the Applicable Fee Percentage times the average daily
amount by which such Lender's Percentage of the Revolving Credit Aggregate
Commitment then in effect (whether used or unused). 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 Lender of its share of the
Revolving Credit Facility Fee based upon its respective Revolving Credit
Percentage. It is expressly understood that the Revolving Credit Facility Fees
described in this Section are not refundable under any circumstances.

         2.9 Mandatory Repayment of Revolving Credit Advances.

         (a) If at any time and for any reason the aggregate outstanding
principal amount of Revolving Credit Advances plus Swing Line Advances, plus the
outstanding Letter of Credit Obligations, shall exceed the Revolving Credit
Aggregate Commitment, Borrower shall immediately reduce any pending request for
a Revolving Credit Advance on such day by the amount of such excess and, to the
extent any excess remains thereafter, repay any Revolving Credit Advances and
Swing Line Advances in an amount equal to the lesser of the outstanding amount
of such Advances and the amount of such remaining excess, with such amounts to
be applied between the Revolving Credit Advances and Swing Line Advances as
determined by the Agent and then, to the extent that any excess remains after
payment in full of all Revolving Credit Advances and Swing Line Advances, to
provide cash collateral in support of any Letter of Credit Obligations in an
amount equal to the lesser of 105% of the amount of such Letter of Credit
Obligations and the amount of such remaining excess, with such cash collateral
to be provided on the basis set forth in Section 9.2 hereof. Borrower
acknowledges that, in connection with any repayment required hereunder, it shall
also be responsible for the reimbursement of any prepayment or other costs
required under Section 11.1 hereof. Any payments made pursuant to this clause
(a) shall be applied first to outstanding Prime-based Advances under the
Revolving Credit, next to Swing Line Advances carried at the Prime-based Rate,
and then to Eurodollar-based Advances of the Revolving Credit, and then to Swing
Line Advances carried at the Quoted Rate.

         (b) To the extent that, on the date any mandatory repayment of the
Revolving Credit Advances under this Section 2.9 or payment pursuant to the
terms of any of the Loan Documents is due, the Indebtedness under the Revolving
Credit or any other Indebtedness to be prepaid is being carried, in whole or in
part, at the Eurodollar-based Rate and no Default or Event of Default has
occurred and is continuing, Borrower may deposit the amount of such mandatory
prepayment in a cash collateral account to be held by the Agent, for and on
behalf of the Revolving Credit Lenders, on such terms and conditions as are
reasonably acceptable to Agent and upon such deposit the obligation of Borrower
to make such mandatory prepayment shall be deemed satisfied. Subject to the
terms and conditions of said cash collateral account, sums on deposit in said
cash collateral account shall be applied (until exhausted) to reduce the
principal balance of the Revolving Credit on the last day of each
Eurodollar-Interest Period attributable to the Eurodollar-based Advances of such
Revolving Advance, thereby avoiding breakage costs under Section 11.1 hereof;
provided, however, that if a Default or Event of Default shall have occurred at
any time while sums are on deposit in the cash collateral account, Agent may, in
its sole discretion, elect to apply such sums to reduce the principal balance of
such Eurodollar-based Advances prior to the last day of the applicable
Eurodollar-Interest Period, and the Borrower will be obligated to pay any
resulting breakage costs under Section 11.1.

         2.10 Optional Reduction or Termination of Revolving Credit Aggregate
Commitment. Borrower may, upon at least five (5) 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 Hundred Thousand
Dollars ($100,000); (ii) each reduction shall be accompanied by the payment of
the Revolving Credit Facility Fee, if any, accrued and unpaid to the date of
such reduction; (iii) Borrower shall prepay in accordance with the terms hereof
the amount, if any, by which the aggregate unpaid principal amount of Revolving

                                       21
<PAGE>

Credit Advances and Swing Line Advances (including, without duplication, any
deemed Advances made under Section 3.6 hereof) outstanding hereunder, plus the
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; (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; and (v) no
such reduction shall reduce the Swing Line Maximum Amount unless Borrower so
elects, provided that the Swing Line Maximum Amount shall at no time be greater
than the Revolving Credit Aggregate Commitment; provided, however that if the
termination or reduction of the Revolving Credit Aggregate Commitment requires
the prepayment of a Eurodollar-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 Eurodollar-based Advance or
such Quoted Rate Advance, then, pursuant to Section 11.1, Borrower shall
compensate the Revolving Credit Lenders and/or the Swing Line Lender for any
losses or, so long as no Default or Event of Default has occurred and is
continuing, Borrower may deposit the amount of such prepayment in a collateral
account as provided in Section 2.9(b). 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 Lender
in accordance with such Revolving Credit Lender's Revolving Percentage thereof,
and will not be available for reinstatement by or readvance to Borrower, and ay
accompanying prepayment of Advances of the Swing Line shall be distributed by
Agent to the Swing Line Lender and will not be available for reinstatement or
readvance to the Borrower. Any reductions of the Revolving Credit Aggregate
Commitment hereunder shall reduce each Revolving Credit Lender's portion thereof
proportionately (based on the applicable Percentages), and shall be permanent
and irrevocable. Any payments made pursuant to this Section shall be applied
first to outstanding Prime-based Advances under the Revolving Credit, next to
Swing Line Advances carried at the Prime-based Rate, then to Eurodollar-based
Advances of the Revolving Credit, and then to Swing Line Advances carried at the
Quoted Rate.

         2.11 Use of Proceeds of Advances. Advances of the Revolving Credit
shall be used to finance working capital and other lawful corporate purposes.

         2.12 Swing Line Advances.

         (a) Commitment. The Swing Line Lender may, on the terms and subject to
the conditions hereinafter set forth (including without limitation Section
2.12(c) hereof), but shall not be required to, make one or more Advances (each
such advance being a "Swing Line Advance") to the Borrower from time to time on
any Business Day during the period from the Effective Date hereof until (but
excluding) the Revolving Credit Maturity Date in an aggregate amount not to
exceed at any one time outstanding the Swing Line Maximum Amount. Subject to the
terms set forth herein, advances, repayments and readvances may be made under
the Swing Line.

         (b) Accrual of Interest and Maturity; Evidence of Indebtedness.

                  (i)      Swing Line Lender shall maintain in accordance with

                           indebtedness of the Borrower to Swing Line Lender
                           resulting from each Swing Line Advance from time to
                           time, including 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 made on any Swing Line Advance from
                           time to time. The entries made in such account or
                           accounts of Swing Line Lender shall be prima facie
                           evidence, absent manifest error, of the existence and
                           amounts of the obligations of the Borrower therein
                           recorded; provided, however, that the failure of
                           Swing Line Lender to maintain such account, as
                           applicable, or any error therein, shall not in any
                           manner affect the obligation of the Borrower to repay
                           the Swing Line Advances (and all other amounts owing
                           with respect thereto) in accordance with the terms of
                           this Agreement.

                  (ii)     The Borrower agrees that, upon the written request of
                           Swing Line Lender, the Borrower will execute and
                           deliver to Swing Line Lender a Swing Line Note.

                  (iii)    Borrower unconditionally promises to pay to the Swing
                           Line Lender the then unpaid principal amount of such
                           Swing Line Advance (plus all accrued and unpaid
                           interest) on the Revolving Credit Maturity Date and
                           on such other dates and in such other amounts as may
                           be required from time to time pursuant to this
                           Agreement. Subject to the terms and conditions
                           hereof, each Swing Line Advance shall, from time to
                           time after the date of such Advance (until paid),
                           bear interest at its Applicable Interest Rate.

         (c)      Requests for Swing Line Advances. Borrower may request a Swing
                  Line Advance by the delivery to Swing Line Lender of a Request

                           repayments. At any time during which the "Sweep to
                           Loan" system is in effect, Swing Line Advances shall
                           be advanced to fund borrowing needs pursuant to the
                           terms of the Sweep Agreement. Each time a Swing Line
                           Advance is made using the "Sweep to Loan" system,
                           Borrower shall be deemed to have certified to the
                           Agent and the Lenders each of the matters set forth
                           in clause (vi) of this Section 2.12(b). Principal and
                           interest on Swing Line Advances requested, or deemed
                           requested, pursuant to this Section shall be paid
                           pursuant to the terms and conditions of the Sweep
                           Agreement without any deduction, setoff or
                           counterclaim whatsoever. Unless sooner paid pursuant
                           to the provisions hereof or the provisions of the
                           Sweep Agreement, the principal amount of the Swing
                           Loans shall be paid in full, together with accrued
                           interest thereon, on the Revolving Credit Maturity
                           Date. Agent may suspend or revoke Borrower's
                           privilege to use the "Sweep to Loan" system at any
                           time and from time to time for any reason and,
                           immediately upon any such revocation, the "Sweep to
                           Loan" system shall no longer be available to Borrower
                           for the funding of Swing Line Advances hereunder (or
                           otherwise), and the regular procedures set forth in
                           this Section 2.12 for the making of Swing Line
                           Advances shall be deemed immediately to apply. Agent
                           may, at its option, also elect to make Swing Line
                           Advances upon Borrower's telephone requests on the
                           basis set forth in the last paragraph of Section 2.3,
                           provided that the Borrower complies with the
                           provisions set forth in this Section 2.12.

         (d)      Disbursement of Swing Line Advances. Upon receiving any
                  executed Request for Swing Line Advance from the Borrower and
                  the satisfaction of the conditions set forth in Section
                  2.12(c) hereof, Swing Line Lender shall make available to
                  Borrower the amount so requested in Dollars not later than
                  4:00 p.m. (Detroit time) on the date of such Advance, by
                  credit to an account of Borrower maintained with Agent or to
                  such other account or third party as the Borrower may
                  reasonably direct in writing in compliance with Section 13.6,
                  provided such direction is timely given. Swing Line Lender
                  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, in each case on behalf of the
                           Borrower (which hereby irrevocably directs the Agent
                           to act on their behalf) request each of the Revolving
                           Credit Lenders (including the Swing Line Lender in
                           its capacity as a Revolving Credit Lender) to make an
                           Advance of the Revolving Credit to Borrower, in an
                           amount equal to such Revolving Credit Lender's
                           Revolving Credit Percentage of the aggregate

                                       24

                           principal amount of the Swing Line Advances
                           outstanding on the date such notice is given (the
                           "Refunded Swing Line Advances"); provided however
                           that the Swing Line Advances carried at the Quoted
                           Rate which are refunded with Revolving Credit
                           Advances at the request of the Swing Line Lender at a
                           time when no Default or Event of Default has occurred

                           11.1 and no losses, costs or expenses may be assessed
                           by the Swing Line Lender against the Borrower or the
                           Revolving Credit Lenders as a consequence of such
                           refunding. The applicable Revolving Credit Advances
                           used to refund any Swing Line Advances shall be
                           Prime-based Advances. 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 2.12(e)(ii) hereof, the Swing
                           Line Lender shall retain its claim against Borrower
                           for any unpaid interest or fees in respect thereof
                           accrued to the date of such refunding. Unless any of
                           the events described in Section 9.1(i) hereof shall
                           have occurred (in which event the procedures of
                           Section 2.12(e)(ii) shall apply) and regardless of
                           whether the conditions precedent set forth in this
                           Agreement to the making of a Revolving Credit Advance
                           are then satisfied (but subject to Section
                           2.12(e)(iii)), each Revolving Credit Lender shall
                           make the proceeds of its Revolving Credit Advance
                           available to the Agent for the benefit of the Swing
                           Line Lender at the office of the Agent specified in
                           Section 2.4(a) hereof prior to 11:00 a.m. Detroit

                           such notice is given, in immediately available funds.
                           The proceeds of such Revolving Credit Advances shall
                           be immediately applied to repay the Refunded Swing
                           Line Advances, subject to Section 11.1 hereof.

                  (ii)     If, prior to the making of an Advance of the
                           Revolving Credit pursuant to Section 2.12(e)(i)
                           hereof, one of the events described in Section 9.1(i)
                           hereof shall have occurred, each Revolving Credit
                           Lender will, on the date such Advance of the
                           Revolving Credit was to have been made, purchase from
                           the Swing Line Lender an undivided participating
                           interest in each Swing Line Advance that was to have
                           been refunded in an amount equal to its Revolving
                           Credit Percentage of such Swing Line Advance. Each
                           Revolving Credit Lender within the time periods
                           specified in Section 2.12(e)(i) hereof, as
                           applicable, shall immediately transfer to the Agent,
                           for the benefit of the Swing Line Lender, in
                           immediately available funds, an amount equal to its
                           Revolving Credit Percentage of the aggregate
                           principal amount of all Swing Line Advances
                           outstanding as of such date. Upon receipt thereof,
                           the Agent will deliver to such Revolving Credit
                           Lender a Swing Line Participation Certificate
                           evidencing such participation.

                           accordance with Section 2.12(e)(i) and (ii),
                           respectively, shall be absolute and unconditional and
                           shall not be affected by any circumstance, including,
                           without limitation, (A) any set-off, counterclaim,
                           recoupment, defense or other right which such
                           Revolving Credit Lender may have against Swing Line
                           Lender, Borrower or any other Person for any reason
                           whatsoever; (B) the occurrence or continuance of any
                           Default or Event of Default; (C) any adverse change
                           in the condition (financial or otherwise) of Borrower
                           or any other Person; (D) any breach of this Agreement
                           or any other Loan Document by Borrower or any other
                           Person; (E) any inability of Borrower to satisfy the
                           conditions precedent to borrowing set forth in this
                           Agreement on the date upon which such Revolving
                           Credit Advance is to be made or such participating
                           interest is to be purchased; (F) the termination of
                           the Revolving Credit Aggregate Commitment hereunder;

                           whatsoever, whether or not similar to any of the
                           foregoing. If any Revolving Credit Lender does not
                           make available to the Agent the amount required

                           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. The obligation of any

                           affected by the failure of any other Revolving Credit
                           Lender to make such amounts available, and no
                           Revolving Credit Lender shall have any liability to
                           Borrower, the Agent, the Swing Line Lender, or any
                           other Revolving Credit Lender or any other party for
                           another Revolving Credit Lender's failure to make
                           available the amounts required under Section
                           2.12(e)(i) or (ii) hereof.

                  (iv)     Notwithstanding the foregoing, no Revolving Credit
                           Lender 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 at least
                           two (2) Business Days prior to the making of such
                           Swing Line Advance by the Swing Line Lender, the

                           Lender that Swing Line Advances should be suspended

                           or Event of Default and stating that such notice is a
                           "notice of default"; provided, however that the
                           obligation of the Revolving Credit Lenders to make
                           such Revolving Credit Advances (or purchase such
                           participations) shall be reinstated upon the date on

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

         (f)      there shall have been (i) no introduction of or change in the
                  interpretation of any law or regulation, (ii) no declaration
                  of a general banking moratorium by banking authorities in the
                  United States, Michigan or the respective jurisdictions in
                  which the Revolving Credit Lenders, the Borrower and the
                  beneficiary of the requested Letter of Credit are located, and
                  (iii) no establishment of any new restrictions by any central
                  bank or other governmental agency or authority on transactions
                  involving letters of credit or on banks generally that, in any
                  case described in this clause (e), would make it unlawful or
                  unduly burdensome for the Issuing Lender to issue or any
                  Revolving Credit Lender to take an assignment of its Revolving
                  Credit Percentage of the requested Letter of Credit or letters
                  of credit generally; and

         (g)      Issuing Lender 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 Lender pursuant hereto
shall constitute the certification by Borrower of the matters set forth in
Sections 3.2 (a) and (b) hereof. The Agent shall be entitled to rely on such
certification without any duty of inquiry.

         3.3 Notice. The Issuing Lender shall deliver to the Agent, concurrently
with or promptly following its issuance of any Letter of Credit, a true and
complete copy of each Letter of Credit. Promptly upon its receipt thereof, with
respect to ay Letter of Credit in excess of $100,000, Agent shall give notice,
substantially in the form attached as Exhibit E, to each Revolving Credit Lender
of the issuance of each Letter of Credit, specifying the amount thereof and the
amount of such Revolving Credit Lender's Percentage thereof.

         3.4 Letter of Credit Fees; Increased Costs. (a) Borrower shall pay
letter of credit fees as follows:

                  (i)      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) shall be paid to the Agent for
                           distribution to the Revolving Credit Lenders in
                           accordance with their Percentages.

                  (ii)     A letter of credit facing fee on the face amount of
                           each Letter of Credit shall be paid to the Agent for
                           distribution to the Issuing Lender for its own
                           account, in accordance with the terms of the
                           applicable Fee Letter.

                                       27
<PAGE>

         (b)      All payments by Borrower to the Agent for distribution to the
                  Issuing Lender or the Revolving Credit Lenders under this
                  Section 3.4 shall be made in Dollars 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
                  Borrower by the Agent. The fees described in clauses (a)(i)
                  and (ii) above (i) shall be nonrefundable under all
                  circumstances, (ii) in the case of fees due under clause
                  (a)(i) above, shall be payable annually in advance and (iii)
                  in the case of fees due under clause (a)(ii) above, shall be
                  payable upon the issuance of such Letter of Credit and upon
                  any amendment thereto or extension thereof. The fees due under
                  clause (a)(i) above shall be determined by multiplying the
                  Applicable Fee Percentage times the undrawn amount of the face
                  amount of each such Letter of Credit on the date of
                  determination, 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.
                  The parties hereto acknowledge that, unless the Issuing Lender
                  otherwise agrees, any material amendment and any extension to
                  a Letter of Credit issued hereunder shall be treated as a new
                  Letter of Credit for the purposes of the letter of credit
                  facing fee.

         (c)      If any change in any law or regulation or in the
                  interpretation thereof by any court or administrative or
                  governmental authority charged with the administration
                  thereof, adopted after the date hereof, 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 Lender or
                  any Revolving Credit Lender or (ii) impose on Issuing Lender
                  or any Revolving Credit Lender 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 Lender or such Revolving Credit Lender
                  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 Lender's or such Revolving Credit
                  Lender's reasonable allocation of the aggregate of such cost
                  increases and expenses resulting from such events), then, upon
                  demand by the Issuing Lender or such Revolving Credit Lender,
                  as the case may be, Borrower shall, within thirty (30) days
                  following demand for payment, pay to Issuing Lender or such
                  Revolving Credit Lender, as the case may be, from time to time
                  as specified by the Issuing Lender or such Revolving Credit
                  Lender, additional amounts which shall be sufficient to
                  compensate the Issuing Lender or such Revolving Credit Lender
                  for such increased cost and expense (together with interest on
                  each such amount from ten days after the date such payment is
                  due until payment in full thereof at the Prime-based Rate),
                  provided that if the Issuing Lender or such Revolving Credit

                                       28
<PAGE>

                  Lender could take any reasonable action, without cost or
                  administrative or other burden or restriction to such Lender,
                  to mitigate or eliminate such cost or expense, it agrees to do
                  so within a reasonable time after becoming aware of the
                  foregoing matters. Each demand for payment under this Section
                  3.4(c) shall be accompanied by a certificate of Issuing Lender
                  or the applicable Revolving Credit Lender setting forth the
                  amount of such increased cost or expense incurred by the
                  Issuing Lender or such Revolving Credit Lender, as the case
                  may be, as a result of any event mentioned in clause (i) or
                  (ii) above, and in reasonable detail, the methodology for
                  calculating and the calculation of such amount, which
                  certificate shall be prepared in good faith and shall be
                  conclusive evidence, absent manifest error, as to the amount
                  thereof.

         3.5 Other Fees. In connection with the Letters of Credit, and in
addition to the Letter of Credit Fees, Borrower shall pay, for the sole account
of the Issuing Lender, standard documentation, administration, payment and
cancellation charges assessed by Issuing Lender 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.

         3.6 Drawings and Demands for Payment Under Letters of Credit.

         (a) If the Issuing Lender shall honor a draft or other demand for
payment presented or made under any Letter of Credit, Borrower agrees to pay to
the Issuing Lender an amount equal to the amount paid by the Issuing Lender in
respect of such draft or other demand under such Letter of Credit and all
reasonable expenses paid or incurred by the Agent relative thereto not later
than 1:00 p.m. (Detroit time), on (i) the Business Day that Borrower receive
notice of such presentment and honor, if such notice is received prior to 11:00
a.m. (Detroit time) or (ii) the Business Day immediately following the day that
Borrower received such notice, if such notice is received after 11:00 a.m.
(Detroit time). Unless Borrower shall have made such payment to the Agent for
the account of the Issuing Lender on such day, the Agent shall be deemed to have
disbursed to Borrower and to have elected to substitute for the reimbursement
obligation, with respect to the applicable Letter of Credit honored by the
Issuing Lender, a Prime-based Advance of the Revolving Credit (which Advance may
be subsequently converted at any time into a Eurodollar-based Advance pursuant
to Section 2.3 hereof) on behalf of and for the account of the Revolving Credit
Lenders in an aggregate amount equal to the amount so paid by the Issuing Lender
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 Borrower under this Section 3.6 shall be deemed satisfied.

         (b) If the Issuing Lender shall honor a draft or other demand for
payment presented or made under any Letter of Credit, the Issuing Lender shall
provide notice thereof to Borrower on the date such draft or demand is honored,
and to each Revolving Credit Lender on such date unless Borrower shall have
satisfied its reimbursement obligations under Section 3.6(a) hereof by payment
to the Agent (for the benefit of the Issuing Lender) on such date. The Issuing
Lender shall further use reasonable efforts to provide notice to Borrower 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 Lender with respect to any Letter of Credit or the rights and
obligations of the parties hereto, including without limitation the obligations
of Borrower under Section 3.6(a) hereof.

         (c) Upon issuance by the Issuing Lender of each Letter of Credit
hereunder, each Revolving Credit Lender shall automatically acquire a pro rata
participation interest in such Letter of Credit and each related Letter of
Credit Payment based on its respective Revolving Credit Percentage. Each
Revolving Credit Lender, 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 Issuing Lender to the Revolving Credit Lenders under Section 3.6(b)
hereof is not given to the Revolving Credit Lenders prior to 2:00 p.m. (Detroit
time) on such date of draft or demand), shall make its Revolving Credit
Percentage of the amount paid by the Issuing Lender, and not reimbursed by
Borrower on such day, in immediately available funds at the principal office of
the Agent for the account of Issuing Lender. If and to the extent such Revolving
Credit Lender shall not have made such pro rata portion available to the Agent,
such Revolving Credit Lender agrees to pay to the Agent for the account of the
Issuing Lender forthwith on demand such amount together with interest thereon,
for each day from the date such amount was paid by the Issuing Lender until such
amount is so made available to the Agent at the Federal Funds Effective Rate for
the first three days and thereafter at a Prime-based 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 Borrower. If such Revolving Credit
Lender shall pay such amount to the Agent for the account of Issuing Lender
together with such interest, if any, such amount so paid shall be deemed to

                                       29
<PAGE>

constitute an Advance by such Revolving Credit Lender disbursed in respect of
the reimbursement obligation of Borrower 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 Lender to make its pro rata
portion of any such amount paid by the Issuing Lender available to the Agent for
the account of Issuing Lender shall not relieve any other Revolving Credit
Lender of its obligation to make available its pro rata portion of such amount,
but no Revolving Credit Lender shall be responsible for failure of any other
Revolving Credit Lender to make such pro rata portion available to the Agent for
the account of Issuing Lender.

         Notwithstanding the foregoing however no Revolving Credit Lender shall
be deemed to have acquired a participation in a Letter of Credit if the officers
of the Issuing Lender immediately responsible for matters concerning this
Agreement shall have received written notice from Agent or any Lender at least
two (2) Business Days prior to the date of the issuance of such Letter of Credit
that the issuance of Letters of Credit should be suspended based on the
occurrence and continuance of a Default or Event of Default and stating that
such notice is a "notice of default"; provided, however that the Revolving
Credit Lenders shall be deemed to have acquired such a participation upon the
date on which such Default or Event of Default has been waived by the requisite
Revolving Credit Lenders, as applicable. In the event that the Issuing Lender
receives such a notice, the Issuing Lender shall have no obligation to issue any
Letter of Credit until such notice is withdrawn by Agent or such Lender or until
the requisite Lenders have waived such Default or Event of Default in accordance
with the terms of this Agreement.

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

         3.7 Obligations Irrevocable. The obligations of Borrower to make
payments to Agent for the account of Issuing Lender or the Revolving Credit
Lenders 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, any Letter of Credit Agreement, any other
                  documentation relating to any Letter of Credit, this Agreement
                  or any of the other Loan Documents (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 Letter of Credit Document;

         (c)      The existence of any claim, setoff, defense or other right
                  which Borrower 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 Lender or any Revolving
                  Credit Lender or any other Person, whether in connection with
                  this Agreement, 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 Lender 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;

                                       30
<PAGE>

         (f)      Any failure, omission, delay or lack on the part of the Agent,
                  Issuing Lender or any Revolving Credit Lender 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 Lender, any Revolving Credit Lender 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 Lender, any
                  Revolving Credit Lender 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 Borrower 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 Borrower has or may have against the
beneficiary of any Letter of Credit shall be available hereunder to Borrower
against the Agent, Issuing Lender or any Revolving Credit Lender. With respect
to any Letter of Credit, nothing contained in this Section 3.7 shall be deemed
to prevent Borrower, after satisfaction in full of the absolute and
unconditional obligations of Borrower hereunder with respect to such Letter of
Credit, 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 Lender or any
Revolving Credit Lender in connection with such Letter of Credit.

         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 Lender 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
Lender 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 Lender's regularly
established practices and procedures and will have no further obligation with
respect thereto. In the administration of Letters of Credit, Issuing Lender
shall not be liable for any action taken or omitted on the advice of counsel,
accountants, appraisers or other experts selected by Issuing Lender with due
care and Issuing Lender may rely upon any notice, communication, certificate or
other statement from Borrower, beneficiaries of Letters of Credit, or any other
Person which Issuing Lender believes to be authentic. Issuing Lender will, upon
request, furnish the Revolving Credit Lenders 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 Lender makes no representation and
shall have no responsibility with respect to (i) the obligations of Borrower 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 Borrower or any other Person, or (iii) any failure or delay in exercising any
rights or powers possessed by Issuing Lender in its capacity as issuer of
Letters of Credit INCLUDING, WITHOUT LIMITATION, LOSSES, COSTS, DAMAGES,
LIABILITIES AND EXPENSES IN ANY WAY OR TO THE EXTENT OWED, IN WHOLE OR IN PART,
UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY
ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ISSUING LENDER, in the absence of
its gross negligence or willful misconduct. Each of the Revolving Credit Lenders
expressly acknowledges that it has made and will continue to make its own
evaluations of Borrower's creditworthiness without reliance on any
representation of Issuing Lender or Issuing Lender's officers, agents and
employees.

                                       31
<PAGE>

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

         3.9 Indemnification. Borrower hereby indemnifies and agrees to hold
harmless the Revolving Credit Lenders, the Issuing Lender and the Agent and
their respective Affiliates, and the respective officers, directors, employees
and agents of such Persons (each an "L/C Indemnified Person"), from and against
any and all claims, damages, losses, liabilities, costs or expenses of any kind
or nature whatsoever which the Revolving Credit Lenders, the Issuing Lender 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 (collectively, the
"L/C Indemnified Amounts"), and none of the Issuing Lender, any Revolving Credit
Lender 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;

         (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;

                  Letter of Credit against presentation of documents which do
                  not strictly comply with the terms of any Letter of Credit

business entity) duly organized and existing in good standing under the laws of
the state or jurisdiction of its incorporation or formation, as applicable, and,
other than as set forth on Schedule 6.1 hereto, each Borrower is duly qualified
and authorized to do business as a foreign corporation in each jurisdiction
where the character of its assets or the nature of its activities makes such
qualification and authorization necessary except where failure to be so
qualified or be in good standing could not reasonably be expected to have a
Material Adverse Effect. Each Borrower has all requisite corporate, limited
liability or partnership power and authority to own all its property (whether
real, personal, tangible or intangible or of any kind whatsoever) and to carry
on its business.

                                       35

         6.2 Due Authorization. Execution, delivery and performance of this
Agreement, and the other Loan Documents, to which each Borrower is party, and
the issuance of the Notes by Borrower (if requested) are within such Person's
corporate, limited liability or partnership power, have been duly authorized,
are not in contravention of any law applicable to such Borrower or the terms of
such Borrower's organizational documents and, except as have been previously
obtained or as referred to in Section 6.10, below, do not require the consent or
approval of any governmental body, agency or authority or any other third party
except to the extent that such consent or approval is not material to the
transactions contemplated by the Loan Documents.

         6.3 Good Title; Leases; Assets; No Liens(a) . (a) Each Borrower, to the
extent applicable, has good and valid title (or, in the case of real property,
good and marketable title) to all assets owned by it, subject only to the Liens
permitted under section 8.2 hereof, and each Borrower has a valid leasehold or
interest as a lessee or a licensee in all of its leased real property;

         (b) There are no Liens on and no financing statements on file with
respect to any of the assets owned by the Borrowers, except for the Liens
permitted pursuant to Section 8.2 of this Agreement.

         6.4 Taxes. Except as set forth on Schedule 6.4 hereof, each Borrower
has filed on or before their respective due dates or within the applicable grace
periods, all United States federal, state, local and other tax returns which are
required to be filed or has obtained extensions for filing such tax returns and
is not delinquent in filing such returns in accordance with such extensions and
has paid all material taxes which have become due pursuant to those returns or
pursuant to any assessments received by any such Borrower, as the case may be,
to the extent such taxes have become due, except to the extent such taxes are
being contested in good faith by appropriate proceedings diligently conducted
and with respect to which adequate provision has been made on the books of such
Borrower as may be required by GAAP.

         6.5 No Defaults. No Borrower is in default under or with respect to any
agreement, instrument or undertaking to which is a party or by which it or any
of its property is bound which would cause or would reasonably be expected to
cause a Material Adverse Effect.

         6.6 Enforceability of Agreement and Loan Documents. This Agreement and
each of the other Loan Documents to which any Borrower is a party (including
without limitation, each Request for Advance), have each been duly executed and
delivered by its duly authorized officers and constitute the valid and binding
obligations of such Borrower, enforceable against such Borrower in accordance
with their respective terms, except as enforcement thereof may be limited by
applicable bankruptcy, reorganization, insolvency, fraudulent conveyance,
moratorium or similar laws affecting the enforcement of creditor's rights,
generally and by general principles of equity (regardless of whether enforcement
is considered in a proceeding in law or equity).

         6.7 Compliance with Laws. (a) Except as disclosed on Schedule 6.7, each
Borrower has complied with all applicable federal, state and local laws,
ordinances, codes, rules, regulations and guidelines (including consent decrees
and administrative orders) including but not limited to Hazardous Material Laws,
and is in compliance with any Requirement of Law, except to the extent that
failure to comply therewith could not reasonably be expected to have a Material
Adverse Effect; and (b) neither the extension of credit made pursuant to this
Agreement or the use of the proceeds thereof by the Borrowers will violate the
Trading with the Enemy Act, as amended, or any of the foreign assets control
regulations of the United States Treasury Department (31 CFR, Subtitle B,
Chapter V, as amended) or any enabling legislation or executive order relating
thereto, or The United and Strengthening America by providing appropriate Tools
Required to Intercept and Obstruct Terrorism ("USA Patriot Act") Act of 2001,

suit, action, proceeding, including, without limitation, any bankruptcy
proceeding or governmental investigation pending against or to the knowledge of
Borrower, threatened against any Borrower (other than any suit, action or
proceeding in which a Borrower is the plaintiff and in which no counterclaim or
cross-claim against such Borrower has been filed), or any judgment, decree,
injunction, rule, or order of any court, government, department, commission,
agency, instrumentality or arbitrator outstanding against any Borrower, nor is
any Borrower in violation of any applicable law, regulation, ordinance, order,
injunction, decree or requirement of any governmental body or court which could
in any of the foregoing events reasonably be expected to have a Material Adverse
Effect.

         6.10 Consents, Approvals and Filings, Etc. Except as set forth on
Schedule 6.10 hereof, no material authorization, consent, approval, license,
qualification or formal exemption from, nor any filing, declaration or
registration with, any court, governmental agency or regulatory authority or any
securities exchange or any other Person (whether or not governmental) is
required in connection with the execution, delivery and performance: (a) by any
Borrower of this Agreement and any of the other Loan Documents to which such
Borrower is a party or (b) by the Borrowers of the grant of Liens granted,
conveyed or otherwise established (or to be granted, conveyed or otherwise
established) by or under this Agreement or the other Loan Documents, as
applicable, except in each case for (i) such matters which have been previously
obtained, and (ii) such filings to be made concurrently herewith or promptly
following the Effective Date as are required by the Collateral Documents to
perfect Liens in favor of the Agent. All such material authorizations, consents,
approvals, licenses, qualifications, exemptions, filings, declarations and
registrations which have previously been obtained or made, as the case may be,
are in full force and effect and, to the best knowledge of Borrower, are not the
subject of any attack or threatened attack (in each case in any material
respect) by appeal or direct proceeding or otherwise.

         6.11 Agreements Affecting Financial Condition. No Borrower is party to
any agreement or instrument or subject to any charter or other corporate
restriction which could reasonably be expected to have a Material Adverse
Effect.

         6.12 No Investment Company or Margin Stock. No Borrower is an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended. No Borrower 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 will be used by any Borrower to purchase or carry 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 therefore, as from
time to time in effect, are used in this paragraph with such meanings.

         6.13 ERISA. No Borrower maintains or contributes to any Pension Plan
subject to Title IV of ERISA, except as set forth on Schedule 6.13 hereto or
otherwise disclosed to the Agent in writing. There is no accumulated funding
deficiency within the meaning of Section 412 of the Internal Revenue Code or
Section 302 of ERISA, or any outstanding liability with respect to any Pension
Plans owed to the PBGC other than future premiums due and owing pursuant to
Section 4007 of ERISA, and no "reportable event" as defined in Section 4043(c)
of ERISA has occurred with respect to any Pension Plan other than an event for
which the notice requirement has been waived by the PBGC. None of the Borrowers
has engaged in a prohibited transaction with respect to any Pension Plan, other
than a prohibited transaction for which an exemption is available and has been
obtained, which could subject such Borrowers to a material tax or penalty
imposed by Section 4975 of the Internal Revenue Code or Section 502(i) of ERISA.
Each Pension Plan is being maintained and funded in accordance with its terms
and is in material compliance with the requirements of the Internal Revenue Code
and ERISA. No Borrower has had a complete or partial withdrawal from any
Multiemployer Plan that has resulted or could reasonably be expected to have
resulted in any Withdrawal Liability and, except as notified to Agent in writing
following the Effective Date, no such Multiemployer Plan is in reorganization
(within the meaning of Section 4241 of ERISA) or insolvent (within the meaning
of Section 4245 of ERISA).

respective businesses nor the properties of any Borrower is affected by any
fire, explosion, accident, strike, lockout or other dispute, drought, storm,
hail, earthquake, embargo, Act of God, or other casualty (except to the extent
such event is covered by insurance sufficient to ensure that upon application of
the proceeds thereof, no Material Adverse Effect could reasonably be expected to
occur) which could reasonably be expected to have a Material Adverse Effect.

         6.15 Environmental and Safety Matters. Except as set forth in Schedules
6.9, 6.10 and 6.15:

                           information received by any Borrower with respect to
                           any alleged violation of any Hazardous Material Law,
                           or

                  (ii)     written complaints, notices or inquiries to any
                           Borrower regarding potential liability of any
                           Borrowers under any Hazardous Material Law; and

         (c)      to the best knowledge of Borrower, no conditions exist at, on
                  or under any property now or previously owned or leased by any
                  Borrower which, with the passage of time, or the giving of
                  notice or both, are reasonably likely to give rise to
                  liability under any Hazardous Material Law or create a
                  significant adverse effect on the value of the property.

         6.16 Subsidiaries. Except as disclosed on Schedule 6.16 hereto as of
the Effective Date, and thereafter, except as disclosed to the Agent in writing

their business substantially as now conducted without known conflict with any
rights of others. Schedule 6.19 contains a true and accurate list of all trade
names and any and all other names used by any Borrower during the five-year
period ending as of the Effective Date.

with all applicable state, federal and foreign laws concerning the issuance of
securities. Except as disclosed on Schedule 6.19, there are no preemptive or
other outstanding rights, options, warrants, conversion rights or similar

of any Equity Interests of any Borrower.

         6.21 Accuracy of Information. (a) The audited financial statements for
the Fiscal Year ended December 31, 2006, furnished to Agent and the Lenders
prior to the Effective Date fairly present in all material respects the

(i) the Borrowers do not have any material contingent obligations (including any
liability for taxes) not disclosed by or reserved against in the opening balance
sheet to be delivered hereunder and (ii) there are no unrealized or anticipated
losses from any present commitment of the Borrowers which contingent obligations
and losses in the aggregate could reasonably be expected to have a Material
Adverse Effect.

         6.22 Solvency. After giving effect to the consummation of the
transactions contemplated by this Agreement and other Loan Documents, each
Borrower will be solvent, able to pay its indebtedness as it matures and will
have capital sufficient to carry on its businesses and all business in which it
is about to engage. This Agreement is being executed and delivered by the
Borrower to Agent and the Lenders in good faith and in exchange for fair,
equivalent consideration. The Borrowers do not intend to nor does management of
the Borrowers believe the Borrowers will incur debts beyond their ability to pay
as they mature. The Borrowers do not contemplate filing a petition in bankruptcy
or for an arrangement or reorganization under the Bankruptcy Code or any similar
law of any jurisdiction now or hereafter in effect relating to any Borrower, nor
does any Borrower have any knowledge of any threatened bankruptcy or insolvency
proceedings against a Borrower.

         6.23 Employee Matters. There are no strikes, slowdowns, work stoppages,
unfair labor practice complaints, grievances, arbitration proceedings or
controversies pending or, to the best knowledge of the Borrower, threatened
against any Borrower by any employees of any Borrower, other than non-material
employee grievances or controversies arising in the ordinary course of business.

         6.24 No Misrepresentation. Neither this Agreement nor any other Loan
Document, certificate, information or report furnished or to be furnished by or
on behalf of a Borrower to Agent or any Lender in connection with any of the
transactions contemplated hereby or thereby, contains a misstatement of material
fact, or omits to state a material fact required to be stated in order to make
the statements contained herein or therein, taken as a whole, not misleading in
the light of the circumstances under which such statements were made. There is
no fact, other than information known to the public generally, known to any
Borrower after diligent inquiry, that could reasonably be expect to have a
Material Adverse Effect that has not expressly been disclosed to Agent in
writing.

                           individually or in the aggregate, which continues
                           beyond any applicable period of cure and which would
                           permit the holder or holders thereto to accelerate
                           such other indebtedness for borrowed money, or
                           require the prepayment, repurchase, redemption or

                           Hundred Fifty Thousand Dollars ($250,000) (or the
                           equivalent thereof in any currency other than

                           otherwise for a period of sixty (60) consecutive days
                           from the date of its entry;

                  (h)      the occurrence of (i) a "reportable event", as
                           defined in ERISA, which is determined by the PBGC to
                           constitute grounds for a distress termination of any
                           Pension Plan subject to Title IV of ERISA maintained
                           or contributed to by or on behalf of any Borrower for
                           the benefit of any of its employees or for the
                           appointment by the appropriate United States District
                           Court of a trustee to administer such Pension Plan
                           and such reportable event is not corrected and such
                           determination is not revoked within thirty (30) days
                           after notice thereof has been given to the plan
                           administrator of such Pension Plan (without limiting
                           any of Agent's or any Lender's other rights or
                           remedies hereunder), or (ii) the termination or the
                           institution of proceedings by the PBGC to terminate
                           any such Pension Plan, or (iii) the appointment of a
                           trustee by the appropriate United States District
                           Court to administer any such Pension Plan, or (iv)
                           the reorganization (within the meaning of Section
                           4241 of ERISA) or insolvency (within the meaning of
                           Section 4245 of ERISA) of any Multiemployer Plan, or
                           receipt of notice from any Multiemployer Plan that it
                           is in reorganization or insolvency, or the complete
                           or partial withdrawal by any Borrower from any
                           Multiemployer Plan, which in the case of any of the
                           foregoing, could reasonably be expected to have a
                           Material Adverse Effect;

                  (i)      except as expressly permitted under this Agreement,
                           any Borrower shall be dissolved (other than a

                           a Guarantor or Borrower) or liquidated (or any

                           the business of any Borrower; or if any Borrower
                           shall have made a general assignment for the benefit
                           of creditors or shall have been adjudicated bankrupt
                           and if not an adjudication based on a filing by a
                           Borrower, it shall not have been dismissed within
                           sixty (60) days, or shall have filed a voluntary
                           petition in bankruptcy or for reorganization or to

                           contested in good faith and for which adequate
                           reserves are made in such party's financial
                           statements); or shall file an answer to a creditor's
                           petition or other petition filed against it,

                           of a receiver or trustee or custodian for any of its
                           property or assets; or such receiver, trustee or
                           custodian shall have been appointed for any of its
                           property or assets (otherwise than upon application
                           or consent of a Borrower ) and shall not have been
                           removed within sixty (60) days; or if an order shall

                           dismissed within sixty (60) days;

                  (j)      the validity, binding effect or enforceability of any
                           subordination provisions relating to any Subordinated
                           Debt shall be contested by any Person party thereto
                           (other than any Lender, Agent, or Issuing Lender), or
                           such subordination provisions shall fail to be
                           enforceable by Agent and the Lenders in accordance
                           with the terms thereof, or the Indebtedness shall for
                           any reason not have the priority contemplated by this
                           Agreement or such subordination provisions; or

                  (k)      any Loan Document shall at any time for any reason

                           accordance with the terms thereof or the terms of any
                           other Loan Document), as applicable, or the validity,
                           binding effect or enforceability thereof shall be
                           contested by any party thereto (other than any
                           Lender, Swing Line Lender, Agent, or Issuing Lender),
                           or any Person shall deny that it has any or further
                           liability or obligation under any Loan Document, or
                           any such Loan Document shall be terminated (other
                           than in accordance with the terms thereof or the
                           terms of any other Loan Document), invalidated,
                           revoked or set aside or in any way cease to give or
                           provide to the Lenders and the Agent the benefits
                           purported to be created thereby.

         9.2 Exercise of Remedies. 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 Lenders, declare the Revolving Credit Aggregate Commitment
terminated; (b) the Agent may, and shall, upon being directed to do so by the
Majority Lenders, 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 the Borrower; (c) upon the
occurrence of any Event of Default specified in Section 9.1(i) and
notwithstanding the lack of any declaration by Agent under preceding clauses (a)
or (b), 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 Lenders, demand immediate delivery of cash
collateral, and each Borrower agrees to deliver such cash collateral upon
demand, in an amount equal to 105% of the maximum amount that may be available
to be drawn at any time prior to the stated expiry of all outstanding Letters of
Credit; (e) the Agent may, and shall, upon being directed to do so by the
Majority Lenders, notify Borrower or any Borrower that interest shall be payable
on demand on all Indebtedness (other than Revolving Credit Advances and Swing
Line Advances, with respect to which Section 2.6 hereof shall govern) owing from
time to time to the Agent or any Lender, at a per annum rate equal to the then
applicable Prime-based Rate plus two percent (2%); and (f) the Agent may, and
shall, upon being directed to do so by the Majority Lenders or the Lenders, as
applicable (subject to the terms hereof), exercise any remedy permitted by this
Agreement, the other Loan Documents or law.

                                       51

         9.3 Rights Cumulative. No delay or failure of Agent and/or Lenders 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 Lenders under this Agreement are cumulative
and not exclusive of any right or remedies which Lenders would otherwise have.

         9.4 Waiver by Borrower 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.

         9.5 Waiver of Defaults. No Event of Default shall be waived by the
Lenders except in a writing signed by an officer of the Agent in accordance with
Section 13.10 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 Lenders. 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 Lenders in enforcing any of their
rights shall constitute a waiver of any of their rights. The Borrower expressly
agrees that this Section may not be waived or modified by the Lenders or Agent
by course of performance, estoppel or otherwise.

         9.6 Set Off. Upon the occurrence and during the continuance of any
Event of Default, each Lender may at any time and from time to time, without
notice to Borrower but subject to the provisions of Section 10.3 hereof (any
requirement for such notice being expressly waived by Borrower), setoff and
apply against any and all of the obligations of Borrower now or hereafter
existing under this Agreement, whether owing to such Lender, any Affiliate of
such Lender or any other Lender 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 Lender to or for the credit or the
account of Borrower and any property of Borrower from time to time in possession
of such Lender, irrespective of whether or not such deposits held or
indebtedness owing by such Lender may be contingent and unmatured and regardless
of whether any Collateral then held by Agent or any Lender is adequate to cover
the Indebtedness. Promptly following any such setoff, such Lender shall give
written notice to Agent and Borrower of the occurrence thereof. Borrower hereby
grants to the Lenders 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 Borrower under this Agreement. The
rights of each Lender under this Section 9.6 are in addition to the other rights
and remedies (including, without limitation, other rights of setoff) which such
Lender may have.

10.      PAYMENTS, RECOVERIES AND COLLECTIONS.

         10.1 Payment Procedure.

         (a) All payments to be made by Borrower shall be made without condition
or deduction for any counterclaim, defense, recoupment or setoff. Except as
otherwise provided herein, all payments made by the Borrower of principal,
interest or fees hereunder shall be made without setoff or counterclaim on the
date specified for payment under this Agreement and must be received by Agent
not later than 1:00 p.m. (Detroit time) on the date such payment is required or
intended to be made in Dollars in immediately available funds to Agent at
Agent's office located at One Detroit Center, Detroit, Michigan 48226-3289, for
the ratable benefit of the Revolving Credit Lenders in the case of payments in
respect of the Revolving Credit and any Letter of Credit Obligations. Any
payment received by the Agent after 1:00 p.m. (Detroit time) shall be deemed
received on the next succeeding Business Day and any applicable interest or fee
shall continue to accrue. Upon receipt of each such payment, the Agent shall
make prompt payment to each applicable Lender, or, in respect of
Eurodollar-based Advances, such Lender's Eurodollar Lending Office, in like
funds and currencies, of all amounts received by it for the account of such
Lender.

                                       52
<PAGE>

         (b) Unless the Agent shall have been notified in writing by Borrower at
least two (2) Business Days prior to the date on which any payment to be made by
Borrower is due that Borrower does not intend to remit such payment, the Agent
may, in its sole discretion and without obligation to do so, assume that
Borrower has remitted such payment when so due and the Agent may, in reliance
upon such assumption, make available to each Revolving Credit Lender, on such
payment date an amount equal to such Lender's share of such assumed payment. If
Borrower has not in fact remitted such payment to the Agent, each Lender shall
forthwith on demand repay to the Agent the amount of such assumed payment made
available or transferred to such Lender, 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 Lender to the date such amount is repaid to the Agent at a
rate per annum equal to the Federal Funds Effective Rate for the first two (2)
Business Days that such amount remains unpaid, and thereafter at a rate of
interest then applicable to such Revolving Credit Advances.

         (c) Subject to the definition of "Interest Period" in Section 1 of this
Agreement, 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 Borrower under this Agreement or any of
the Notes (including without limitation, payments under the Swing Line and/or
Swing Line Note) shall be made without setoff or counterclaim, as aforesaid,
and, subject to full compliance by each Lender (and each assignee and
participant pursuant to Section 13.8) with Section 13.13, 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 (other than any taxes on the overall income, net
income, net profits or net receipts or similar taxes (or any franchise taxes
imposed in lieu of such taxes) on the Agent or any Lender (or any branch
maintained by Agent or a Lender) as a result of a present or former connection
between the Agent or such Lender and the governmental authority, political
subdivision, federation or organization imposing such taxes), unless Borrower is
compelled by law to make payment subject to such tax. In such event, Borrower
shall:

                  (i)      pay to the Agent for Agent's own account and/or, as
                           the case may be, for the account of the Lenders such
                           additional amounts as may be necessary to ensure that
                           the Agent and/or such Lender or Lenders (including
                           Swing Line Lender) 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 Lender or Lenders, as the case may be,
                           such certificates or certified copy receipts as the
                           Agent or such Lender or Lenders (including Swing Line
                           Lender) shall reasonably require as proof of the
                           payment by Borrower of any such taxes payable by
                           Borrower.

As used herein, the terms "tax", "taxes" and "taxation" include all taxes,
levies, imposts, duties, fees, deductions and withholdings or similar charges
together with interest (and any taxes payable upon the amounts paid or payable
pursuant to this Section 10.1) thereon. Borrower shall be reimbursed by the
applicable Lender for any payment made by Borrower under this Section 10.1 if
the applicable Lender is not in compliance with its obligations under Section
13.13 at the time of the Borrower's payment.

         10.2 Application of Proceeds of Collateral. Notwithstanding anything to
the contrary in this Agreement, following the occurrence of any Event of Default
under Section 9.1(i), and following the occurrence of any other Event of Default
and the termination of the Revolving Credit Aggregate Commitment, the

                                       53
<PAGE>

acceleration of any Indebtedness arising under this Agreement or the exercise of
any other remedy in each case by the requisite Lenders under Section 9.2 hereof,
the Agent shall apply the proceeds of any Collateral, together with any offsets,
voluntary payments by any Borrower or others and any other sums received or
collected in respect of the Indebtedness first, to pay all incurred and unpaid
fees and expenses of the Agent under the Loan Documents and any protective
advances made by Agent with respect to the Collateral under or pursuant to the
terms of any Loan Document, next, to pay any fees and expenses owed to the
Issuing Lender hereunder, next, to the Indebtedness under the Revolving Credit
(including the Swing Line and any Reimbursement Obligations), on a pro rata
basis, next to any obligations owing by any Borrower under any Hedging
Agreements on a pro rata basis, next, to any other Indebtedness on a pro rata
basis, and then, if there is any excess, to the Borrowers, as the case may be.

         10.3 Pro-rata Recovery. If any Lender shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of setoff or otherwise)
on account of principal of, or interest on, any of the Advances made by it, or
the participations in Letter of Credit Obligations or Swing Line Advances held
by it in excess of its pro rata share of payments then or thereafter obtained by
all Lenders upon principal of and interest on all such Indebtedness, such Lender
shall purchase from the other Lenders such participations in the Revolving
Credit, and/or the Letter of Credit Obligation held by them as shall be
necessary to cause such purchasing Lender to share the excess payment or other
recovery ratably in accordance with the applicable Percentages of the Lenders;
provided, however, that if all or any portion of the excess payment or other
recovery is thereafter recovered from such purchasing holder, the purchase shall
be rescinded and the purchase price restored to the extent of such recovery, but
without interest.

11.      CHANGES IN LAW OR CIRCUMSTANCES; INCREASED COSTS.

         11.1 Reimbursement of Prepayment Costs. If (i) Borrower makes any
payment of principal with respect to any Eurodollar-based Advance on any day
other than the last day of the Interest Period applicable thereto (whether
voluntarily, pursuant to any mandatory provisions hereof, by acceleration, or
otherwise); (ii) 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 (except as described in Section 2.5(e)); (iii) Borrower fails
to borrow, refund or convert any Eurodollar-based Advance after notice has been
given by Borrower to Agent in accordance with the terms hereof requesting such
Advance; or (iv) or if the Borrower fails to make any payment of principal in
respect of a Eurodollar-based Advance when due, the Borrower shall reimburse
Agent for itself and/or on behalf of any Lender, as the case may be, within ten
(10) Business Days of written demand therefor for any resulting loss, cost or
expense incurred (excluding the loss of any Applicable Margin) by Agent and
Lenders, 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 Lenders, as
the case may be, shall have funded or committed to fund such Advance. The amount
payable hereunder by Borrower to Agent for itself and/or on behalf of any
Lender, as the case may be, shall be deemed to equal 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 Lenders, as the case
may be) which would have accrued to Agent and Lenders, 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 Lender under this paragraph shall be made as though such Lender
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 Lender may fund any Eurodollar-based Advance in any
manner it deems fit and the foregoing assumptions shall be utilized only for the
purpose of the calculation of amounts payable under this paragraph. Upon the
written request of Borrower, Agent and Lenders shall deliver to Borrower a
certificate setting forth the basis for determining such losses, costs and
expenses, which certificate shall be conclusively presumed correct, absent
manifest error.

         11.2 Eurodollar Lending Office. For any Eurodollar Advance, if Agent or
a Lender, as applicable, shall designate a Eurodollar Lending Office which
maintains books separate from those of the rest of Agent or such Lender, Agent
or such Lender, as the case may be, shall have the option of maintaining and
carrying the relevant Advance on the books of such Eurodollar Lending Office.

         11.3 Circumstances Affecting Eurodollar-based Rate Availability. If,
with respect to any Eurodollar-Interest Period, Agent or the Majority Lenders
(after consultation with Agent) shall determine in good faith 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 Lenders for such Eurodollar-Interest Period, then Agent shall
forthwith give notice thereof to Borrower. Thereafter, until Agent notifies
Borrower that such circumstances no longer exist, (i) the obligation of Lenders
to make Eurodollar-based Advances, and the right of Borrower to convert an
Advance to or refund an Advance as a Eurodollar-based Advance, as the case may
be, shall be suspended, and (ii) effective upon the last day of each
Eurodollar-Interest Period related to any existing Eurodollar-based Advance,
each such Eurodollar-based Advance shall automatically be converted into a
Prime-based Advance (without regard to satisfaction of any conditions to
conversion contained elsewhere herein).

         11.4 Laws Affecting Eurodollar-based Advance Availability. If, after
the date of this Agreement, the adoption or 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 Lenders
(or any of their respective Eurodollar 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 Lenders (or any of their
respective Eurodollar Lending Offices) to honor its obligations hereunder to
make or maintain any Advance with interest at the Eurodollar-based Rate, such
Lender shall forthwith give notice thereof to Borrower and to Agent. Thereafter,
(a) the obligations of the applicable Lenders to make Eurodollar-based Advances
and the right of Borrower to convert an Advance into or refund an Advance as a
Eurodollar-based Advance shall be suspended and thereafter Borrower 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 Lenders may not
lawfully continue to maintain an Advance to the end of the then current
Eurodollar-Interest Period applicable thereto as a Eurodollar-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
Eurodollar-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.

         11.5 Increased Cost of Eurodollar-based Advances. If, after the date of
this Agreement, the adoption or introduction of, or any change in, any
applicable law, rule or regulation 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 any of the
Lenders (or any of their respective Eurodollar Lending Offices) with any request
or directive (whether or not having the force of law) of any such authority,
central bank or comparable agency:

                  (a)      shall subject any of the Lenders (or any of their
                           respective Eurodollar 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 Lenders (or any of their respective Eurodollar
                           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 Lenders or any of their respective Eurodollar
                           Lending Offices); 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),

                                       55
<PAGE>

                           special deposit or similar requirement against assets
                           of, deposits with or for the account of, or credit
                           extended by, any of the Lenders (or any of their
                           respective Eurodollar Lending Offices) or shall
                           impose on any of the Lenders (or any of their
                           respective Eurodollar Lending Offices) or the foreign
                           exchange and interbank markets any other condition
                           affecting any Advance;

and the result of any of the foregoing matters is to increase the costs to any
of the Lenders of maintaining any part of the Indebtedness hereunder as a
Eurodollar-based Advance or to reduce the amount of any sum received or
receivable by any of the Lenders under this Agreement in respect of a
Eurodollar-based Advance, then such Lender shall promptly notify Agent, and
Agent shall promptly notify Borrower of such fact and demand compensation
therefor and, within ten (10) Business Days after such notice, Borrower agrees
to pay to such Lender or Lenders such additional amount or amounts as will
compensate such Lender or Lenders for such increased cost or reduction, provided
that each Lender agrees to take any reasonable action, to the extent such action
could be taken without cost or administrative or other burden or restriction to
such Lender, to mitigate or eliminate such cost or reduction, within a
reasonable time after becoming aware of the foregoing matters. Agent will
promptly notify Borrower of any event of which it has knowledge which will
entitle Lenders to compensation pursuant to this Section, or which will cause
Borrower to incur additional liability under Section 11.1 hereof, provided that
Agent shall incur no liability whatsoever to the Lenders or Borrower in the
event it fails to do so. A certificate of Agent (or such Lender, if applicable)
setting forth the basis for determining such additional amount or amounts
necessary to compensate such Lender or Lenders shall accompany such demand and
shall be conclusively presumed to be correct absent manifest error.

         11.6 Capital Adequacy and Other Increased Costs.

                  (a)      If, after the date of this Agreement, the adoption or
                           introduction 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 Lender or Agent, or
                           any interpretation or administration thereof by any
                           governmental authority charged with the
                           interpretation or administration thereof, or
                           compliance by any Lender 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 to be maintained by such
                           Lender or Agent (or any corporation controlling such
                           Lender or Agent) and such Lender or Agent, as the
                           case may be, determines that the amount of such
                           capital is increased by or based upon the existence
                           of such Lender's or Agent's obligations or Advances
                           hereunder and such increase has the effect of
                           reducing the rate of return on such Lender'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 Lender 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 Lender or Agent
                           to be material (collectively, "Increased Costs"),
                           then Agent or such Lender shall notify Borrower, and
                           thereafter Borrower shall pay to such Lender or
                           Agent, as the case may be, within ten (10) Business
                           Days of written demand therefor from such Lender or
                           Agent, additional amounts sufficient to compensate
                           such Lender or Agent (or such controlling
                           corporation) for any increase in the amount of
                           capital and reduced rate of return which such Lender
                           or Agent reasonably determines to be allocable to the
                           existence of such Lender's or Agent's obligations or
                           Advances hereunder. A statement setting forth the
                           amount of such compensation, the methodology for the
                           calculation and the calculation thereof which shall
                           also be prepared in good faith and in reasonable
                           detail by such Lender or Agent, as the case may be,
                           shall be submitted by such Lender or by Agent to
                           Borrower, reasonably promptly after becoming aware of
                           any event described in this Section 11.6(a) and shall
                           be conclusively presumed to be correct, absent
                           manifest error.

<PAGE>

                  (b)      Notwithstanding the foregoing, however, Borrower
                           shall not be required to pay any increased costs
                           under Sections 11.5, 11.6 or 3.4(c) for any period
                           ending prior to the date that is 180 days prior to
                           the making of a Lender'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 Lender'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 Lender becomes aware of the
                           applicable change in law or other event resulting in
                           such increased costs.

         11.7 Right of Lenders to Fund through Branches and Affiliates. Each
Lender (including without limitation, the Swing Line Lender) may, if it so
elects, fulfill its commitment as to any Advance hereunder by designating a
branch or Affiliate of such Lender to make such Advance; provided that (a) such
Lender shall remain solely responsible for the performances of its obligations
hereunder and (b) no such designation shall result in any material increased
costs to Borrower.

         11.8 Margin Adjustment. Adjustments to the Applicable Margins and the
Applicable Fee Percentages, based on Schedule 1.1, shall be implemented on a
quarterly basis as follows:

                  (a)      Such adjustments shall be given prospective effect
                           only, effective as to all Advances outstanding
                           hereunder, the Applicable Fee Percentage and the
                           Letter of Credit Fee, upon the date of delivery of
                           the financial statements under Sections 7.1(a) and
                           7.1(b) hereunder and the Covenant Compliance Report
                           under Section 7.2(a) hereof, in each case
                           establishing applicability of the appropriate
                           adjustment and in each case with no retroactivity or
                           claw-back. In the event Borrower shall fail timely to
                           deliver such financial statements or the Covenant
                           Compliance Report and such failure continues for
                           three (3) days, then (but without affecting the Event
                           of Default resulting therefrom) from the date
                           delivery of such financial statements and report was
                           required until such financial statements and report
                           are delivered, the Applicable Margins and Applicable
                           Fee Percentages shall be at the highest level on the
                           Pricing Matrix attached to this Agreement as Schedule
                           1.1.

                  (b)      From the Effective Date until the date of delivery of
                           the financial statements under Section 7.1(b) hereof,
                           and the Covenant Compliance Report under Section
                           7.2(a) hereof, reflecting two (2) consecutive,
                           profitable quarters of earnings, the Applicable
                           Margins and Applicable Fee Percentages shall be those
                           set forth under the Level III column of the pricing
                           matrix attached to this Agreement as Schedule 1.1.
                           Thereafter, Applicable Margins and Applicable Fee
                           Percentages shall be based upon the quarterly
                           financial statements and Covenant Compliance Reports,
                           subject to recalculation as provided in Section
                           11.8(a) above.

12.      AGENT.

         12.1 Appointment of Agent. Each Lender and the holder of each Note (if
issued) irrevocably appoints and authorizes the Agent to act on behalf of such
Lender 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 Lenders 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 Borrower.

                                       57
<PAGE>

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

         12.3 Scope of Agent's Duties. The Agent shall have no duties or
responsibilities except those expressly set forth herein, and shall not, by
reason of this Agreement or otherwise, have a fiduciary relationship with any
Lender (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
Lender 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 Lenders (or all of
the Lenders for those acts requiring consent of all of the Lenders) INCLUDING,
WITHOUT LIMITATION, LOSSES, COSTS, DAMAGES, LIABILITIES AND EXPENSES IN ANY WAY
OR TO THE EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT
LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF ANY
KIND BY AGENT (except for its or their own willful 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
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 their respective obligations hereunder
or thereunder, or (d) the satisfaction of any condition hereunder or thereunder,
including without limitation in connection with 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, independent
public accountants and other experts selected by it and shall not be liable to
the Lenders (except as to money or property received by them or their authorized
agents), for the negligence or misconduct of any such agent selected by it with
reasonable care or for any action taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts.

         12.4 Successor Agent. Agent may resign as such at any time upon at
least thirty (30) days prior notice to Borrower and each of the Lenders. If
Agent at any time shall resign or if the office of Agent shall become vacant for
any other reason, Majority Lenders shall, by written instrument, appoint
successor agent(s) ("Successor Agent") satisfactory to such Majority Lenders
and, so long as no Default or Event of Default has occurred and is continuing,
to Borrower (which approval shall not be unreasonably withheld or delayed);
provided, however that any such successor Agent shall be a bank or a trust
company or other financial institution which maintains an office in the United
States, or a commercial bank organized under the laws of the United States or
any state thereof, or any Affiliate of such bank or trust company or other
financial institution which is engaged in the banking business, and shall have a
combined capital and surplus of at least $500,000,000. Such Successor Agent
shall thereupon become the Agent hereunder, as applicable, and Agent shall
deliver or cause to be delivered to any successor agent such documents of
transfer and assignment as such Successor Agent may reasonably request. If a
Successor Agent 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
Lenders and, if applicable, Borrower, is made and accepted, or if no such
temporary successor is appointed as provided above by the resigning Agent, the
Majority Lenders shall thereafter perform all of the duties of the resigning
Agent hereunder until such appointment by the Majority Lenders and, if
applicable, Borrower, 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

                                       58
<PAGE>

hereunder. Upon such succession of any such Successor Agent, the resigning Agent
shall be discharged from its duties and obligations, in its capacity as Agent
hereunder, except for its gross negligence or willful misconduct arising prior
to its resignation hereunder, and the provisions of this Article 12 shall
continue in effect for the benefit of the resigning Agent in respect of any
actions taken or omitted to be taken by it while it was acting as Agent.

         12.5 Credit Decisions. Each Lender acknowledges that it has,
independently of Agent and each other Lender and based on the financial
statements of Borrower 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 Lender also acknowledges that it will,
independently of Agent and each other Lender 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, any Loan Document or any other document executed pursuant hereto.

         12.6 Authority of Agent to Enforce This Agreement. Each Lender, subject
to the terms and conditions of this Agreement, grants the Agent full power and
authority as attorney-in-fact to institute and maintain actions, suits or
proceedings for the collection and enforcement of any Indebtedness outstanding
under this Agreement or any other Loan Document and to file such proofs of debt
or other documents as may be necessary to have the claims of the Lenders allowed
in any proceeding relative to any Borrower, or their respective creditors or
affecting their respective properties, and to take such other actions which
Agent considers to be necessary or desirable for the protection, collection and
enforcement of the Notes, this Agreement or the other Loan Documents.

         12.7 Indemnification of Agent. The Lenders agree (which agreement shall
survive the expiration or termination of this Agreement) to indemnify the Agent
and its Affiliates (to the extent not reimbursed by Borrower, but without
limiting any obligation of Borrower to make such reimbursement), ratably
according to their respective Revolving Credit Percentages, from and against any
and all claims, damages, losses, liabilities, costs or expenses of any kind or
nature whatsoever (including, without limitation, reasonable 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 INCLUDING, WITHOUT LIMITATION, CLAIMS,
DAMAGES, LOSSES, LIABILITIES, COSTS AND EXPENSES IN ANY WAY OR TO THE EXTENT
OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR
CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY
AGENT, LENDERS OR THEIR AFFILIATES; provided, however, that no Lender shall be
liable for any portion of such claims, damages, losses, liabilities, costs or
expenses resulting from the Agent's or its Affiliate's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender agrees to
reimburse the Agent and its Affiliates promptly upon demand for its ratable
share of any reasonable out-of-pocket expenses (including, without limitation,
reasonable fees and expenses of house and outside counsel) incurred by the Agent
and its Affiliates in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement or any of the other Loan
Documents, to the extent that the Agent and its Affiliates are not reimbursed
for such expenses by Borrower, but without limiting the obligation of Borrower
to make such reimbursement. Each Lender 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 Lenders pursuant to this Section, provided
that, if the Agent or its Affiliates are subsequently reimbursed by Borrower for
such amounts, they shall refund to the Lenders 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 become impaired as determined in the Agent's
reasonable judgment or Agent shall elect in its sole discretion to have such
indemnity confirmed by the Lenders (as to specific matters or otherwise), Agent
shall give notice thereof to each Lender and, until such additional indemnity is
provided or such existing indemnity is confirmed, the Agent may cease, or not
commence, to take any action. Any amounts paid by the Lenders hereunder to the
Agent or its Affiliates shall be deemed to constitute part of the Indebtedness
hereunder.

                                       59
<PAGE>

         12.8 Knowledge of Default. It is expressly understood and agreed that
the Agent shall be entitled to assume that no Default or Event of Default has
occurred and is continuing, unless the officers of the Agent immediately
responsible for matters concerning this Agreement shall have received a written
notice from a Lender or a Borrower specifying such Default or Event of Default
and stating that such notice is a "notice of default". Upon receiving such a
notice, the Agent shall promptly notify each Lender of such Default or Event of
Default and provide each Lender with a copy of such notice and shall endeavor to
provide such notice to the Lenders within three (3) Business Days (but without
any liability whatsoever in the event of its failure to do so). The Agent shall
also furnish the Lenders, promptly upon receipt, with copies of all other
notices or other information required to be provided by Borrower hereunder.

         12.9 Agent's Authorization; Action by Lenders. Except as otherwise
expressly provided herein, whenever the Agent is authorized and empowered
hereunder on behalf of the Lenders to give any approval or consent, or to make
any request, or to take any other action on behalf of the Lenders (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 Lenders or the Lenders, as applicable
hereunder. Action that may be taken by the Majority Lenders, any other specified
Percentage of the Lenders or all of the Lenders, as the case may be (as provided
for hereunder) may be taken (i) pursuant to a vote of the requisite percentages
of the Lenders as required hereunder at a meeting (which may be held by
telephone conference call), provided that Agent exercises good faith, diligent
efforts to give all of the Lenders reasonable advance notice of the meeting, or
(ii) pursuant to the written consent of the requisite percentages of the Lenders
as required hereunder, provided that all of the Lenders are given reasonable
advance notice of the requests for such consent.

         12.10 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
Lenders or all of the Lenders, 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 reasonable judgment of the Agent, such action or omission
may expose the Agent to personal liability for which Agent has not been
satisfactorily indemnified hereunder 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 Lender (other than
the Agent, acting in its capacity as agent) shall be entitled to take any
enforcement action of any kind under this Agreement or any of the other Loan
Documents.

         12.11 Collateral Matters.

         (a) The Agent is authorized on behalf of all the Lenders, for
themselves and on behalf of each Lender Affiliate that is party to any Hedging
Agreement with a Borrower, without the necessity of any notice to or further
consent from the Lenders or any such Lender Affiliate, 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 Lenders for themselves and on behalf of each Lender Affiliate
that is party to any Hedging Agreement with a Borrower irrevocably authorize the
Agent, in its reasonable discretion, to the full extent set forth in the
post-amble to Section 13.10 hereof, (1) to release or terminate any Lien granted
to or held by the Agent upon any Collateral (a) 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; (b) constituting
property (including, without limitation, Equity Interests in any Person) sold or
to be sold or disposed of as part of or in connection with any disposition
(whether by sale, by merger or by any other form of transaction and including
the property of any Subsidiary that is disposed of as permitted hereby)
permitted in accordance with the terms of this Agreement; (c) constituting
property in which a Borrower owned no interest at the time the Lien was granted

                                       60
<PAGE>

or at any time thereafter; or (d) if approved, authorized or ratified in writing
by the Majority Lenders, or all the Lenders, as the case may be, as provided in
Section 13.10; (2) to subordinate the Lien granted to or held by Agent on any
Collateral to any other holder of a Lien on such Collateral which is permitted
by Section 8.2(b) hereof; and (3) if all of the Equity Interests held by the
Borrowers in any Person are sold or otherwise transferred to any transferee
other than Borrower or a Subsidiary of Borrower as part of or in connection with
any disposition (whether by sale, by merger or by any other form of transaction)
permitted in accordance with the terms of this Agreement, to release such Person
from all of its obligations under the Loan Documents (including, without
limitation, under any Guaranty). Upon request by the Agent at any time, the
Lenders will confirm in writing the Agent's authority to release particular
types or items of Collateral pursuant to this Section 12.11(b).

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

         12.13 Agent's Fees. Until the Indebtedness has been repaid and
discharged in full and no commitment to extend any credit hereunder is
outstanding, Borrower shall pay to the Agent, as applicable, any agency or other
fee(s) set forth (or to be set forth from time to time) in the applicable Fee
Letter on the terms set forth therein. The agency fees referred to in this
Section 12.13 shall not be refundable under any circumstances.

         12.14 Documentation Agent or other Titles. Any Lender identified on the
facing page or signature page of this Agreement or in any amendment hereto or as
designated with consent of the Agent in any assignment agreement as Lead
Arranger, Documentation Agent, Syndications Agent or any similar titles, shall
not have any right, power, obligation, liability, responsibility or duty under
this Agreement as a result of such title other than those applicable to all
Lenders as such. Without limiting the foregoing, the Lenders so identified shall
not have or be deemed to have any fiduciary relationship with any Lender as a
result of such title. Each Lender acknowledges that it has not relied, and will
not rely, on the Lender so identified in deciding to enter into this Agreement
or in taking or not taking action hereunder.

13.      MISCELLANEOUS.

         13.1 Accounting Principles. Where the character or amount of any asset
or liability or item of income or expense is required to be determined or any
consolidation or other accounting computation is required to be made for the
purposes of this Agreement, it shall be done, unless otherwise specified herein,
in accordance with GAAP.

         13.2 Consent to Jurisdiction. The Borrower, the Agent and Lenders
hereby irrevocably submit to the non-exclusive jurisdiction of any United States
Federal Court or Texas state court sitting in Houston, Texas in any action or
proceeding arising out of or relating to this Agreement or any of the Loan
Documents and the Borrower, Agent and Lenders hereby irrevocably agree that all
claims in respect of such action or proceeding may be heard and determined in
any such United States Federal Court or Texas state court. Each Borrower
irrevocably consents to the service of any and all process in any such action or
proceeding brought in any court in or of the State of Texas by the delivery of
copies of such process to it at the applicable addresses specified on the
signature page hereto or by certified mail directed to such address or such
other address as may be designated by it in a notice to the other parties that
complies as to delivery with the terms of Section 13.6. Nothing in this Section
shall affect the right of the Lenders and the Agent to serve process in any
other manner permitted by law or limit the right of the Lenders or the Agent (or
any of them) to bring any such action or proceeding against any Borrower or any
of their property in the courts with subject matter jurisdiction of any other
jurisdiction. Borrower irrevocably waives any objection to the laying of venue
of any such suit or proceeding in the above described courts.

                                       61
<PAGE>

         13.3 Law of Texas. This Agreement, the Notes and the other Loan
Documents shall be governed by and construed and enforced in accordance with the
laws of the State of Texas (without regard to its conflict of laws provisions).
Whenever possible each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Agreement shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining provisions
of this Agreement.

         13.4 Interest. Agent, Lenders, Borrowers and any other parties to the
Loan Documents intend to contract in strict compliance with applicable usury law
from time to time in effect. In furtherance thereof such Persons stipulate and
agree that none of the terms and provisions contained in the Loan Documents
shall ever be construed to create a contract to pay, for the use, forbearance or
detention of money, interest in excess of the maximum amount of interest
permitted to be charged by applicable law from time to time in effect. Neither
Borrower nor any present or future guarantors, endorsers, or other Persons
hereafter becoming liable for payment of any Indebtedness shall ever be liable
for unearned interest thereon or shall ever be required to pay interest thereon
in excess of the maximum amount that may be lawfully contracted for, charged, or
received under applicable law from time to time in effect, and the provisions of
this section shall control over all other provisions of the Loan Documents which
may be in conflict or apparent conflict herewith. Agent and Lenders expressly
disavow any intention to contract for, charge, or collect excessive unearned
interest or finance charges in the event the maturity of any Indebtedness is
accelerated. If (a) the maturity of any Indebtedness is accelerated for any
reason, (b) any Indebtedness is prepaid and as a result any amounts held to
constitute interest are determined to be in excess of the legal maximum, or (c)
Agent or any Lender or any other holder of any or all of the Indebtedness shall
otherwise collect moneys which are determined to constitute interest which would
otherwise increase the interest on any or all of the Indebtedness to an amount
in excess of that permitted to be charged by applicable law then in effect, then
all sums determined to constitute interest in excess of such legal limit shall,
without penalty, be promptly applied to reduce the then outstanding principal of
the related Indebtedness or, at such Lender's or holder's option, promptly
returned to Borrower or the other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable law, Agent,
Lenders, Borrowers (and any other payors thereof) shall to the greatest extent
permitted under applicable law, (i) characterize any non-principal payment as an
expense, fee or premium rather than as interest, (ii) exclude voluntary
prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and
spread the total amount of interest throughout the entire contemplated term of
the instruments evidencing the Indebtedness in accordance with the amounts
outstanding from time to time thereunder and the maximum legal rate of interest
from time to time in effect under applicable law in order to lawfully contract
for, charge, or receive the maximum amount of interest permitted under
applicable law. In the event applicable law provides for an interest ceiling
under Chapter 303 of the Texas Finance Code (the "Texas Finance Code") as
amended, for that day, the ceiling shall be the "weekly ceiling" as defined in
the Texas Finance Code, provided that if any applicable law permits greater
interest, the law permitting the greatest interest shall apply. As used in this
section the term "applicable law" means the laws of the State of Texas or the
laws of the United States of America, whichever laws allow the greater interest,
as such laws now exist or may be changed or amended or come into effect in the
future.

         13.5 Closing Costs and Other Costs; Indemnification.

         (a) Borrower shall pay or reimburse (a) Agent and its Affiliates for
payment of, on demand, all reasonable costs and expenses, including, by way of
description and not limitation, reasonable in-house and outside attorney fees
and advances, appraisal and accounting fees, lien search fees, and required
travel costs, incurred by Agent and its Affiliates in connection with the
commitment, consummation and closing of the loans contemplated hereby, or in
connection with the administration or enforcement of this Agreement or the other
Loan Documents (including the obtaining of legal advice regarding the rights and
responsibilities of the parties hereto) or any refinancing or restructuring of
the loans or Advances provided under this Agreement or the other Loan Documents,
or any amendment or modification thereof requested by Borrower, and (b) Agent
and its Affiliates and each of the Lenders, as the case may be, for all stamp
and other taxes and duties payable or determined to be payable in connection
with the execution, delivery, filing or recording of this Agreement and the
other Loan Documents and the consummation of the transactions contemplated

                                       62
<PAGE>

hereby, and any and all liabilities with respect to or resulting from any delay
in paying or omitting to pay such taxes or duties. Furthermore, all reasonable
costs and expenses, including without limitation attorney fees, incurred by
Agent and its Affiliates and, after the occurrence and during the continuance of
an Event of Default, by the Lenders in revising, preserving, protecting,
exercising or enforcing any of its or any of the Lenders' rights against
Borrower or any other Borrower, or otherwise incurred by Agent and its
Affiliates and the Lenders in connection with any Event of Default or the
enforcement of the loans (whether incurred through negotiations, legal
proceedings or otherwise), including by way of description and not limitation,
such charges in any court or bankruptcy proceedings or arising out of any claim
or action by any person against Agent, its Affiliates, or any Lender which would
not have been asserted were it not for Agent's or such Affiliate's or Lender's
relationship with Borrower hereunder or otherwise, shall also be paid by
Borrower. All of said amounts required to be paid by Borrower hereunder and not
paid forthwith upon demand, as aforesaid, shall bear interest, from the date
incurred to the date payment is received by Agent, at the Prime-based Rate, plus
two percent (2%).

         (b) Borrower agrees to indemnify and hold Agent and each of the Lenders
(and their respective Affiliates) harmless from all loss, cost, damage,
liability or expenses, including reasonable house and outside attorneys' fees
and disbursements (but without duplication of such fees and disbursements for
the same services), incurred by Agent and each of the Lenders by reason of an
Event of Default, or enforcing the obligations of any Borrower under this
Agreement or any of the other Loan Documents, as applicable, or in the
prosecution or defense of any action or proceeding concerning any matter growing
out of or connected with this Agreement or any of the Loan Documents,

INCLUDING, WITHOUT LIMITATION, LOSSES, COSTS, DAMAGES, LIABILITIES AND EXPENSES
IN ANY WAY OR TO THE EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY
OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR
OMISSION OF ANY KIND BY AGENT, LENDERS OR THEIR AFFILIATES

excluding, however, any loss, cost, damage, liability or expenses to the extent
arising as a result of the gross negligence or willful misconduct of the party
seeking to be indemnified under this Section 13.5(b).

         (c) The Borrower agrees to defend, indemnify and hold harmless Agent
and each Lender (and their respective Affiliates), and their respective
employees, agents, officers and directors from and against any and all claims,
demands, penalties, fines, liabilities, settlements, damages, costs or expenses
of whatever kind or nature (including without limitation, reasonable attorneys
and consultants fees, investigation and laboratory fees, environmental studies
required by Agent or any Lender in connection with the violation of Hazardous
Material Laws), court costs and litigation expenses, arising out of or related
to (i) the presence, use, disposal, release or threatened release of any
Hazardous Materials on, from or affecting any premises owned or occupied by any
Borrower in violation of or the non-compliance with applicable Hazardous
Material Laws, (ii) any personal injury (including wrongful death) or property
damage (real or personal) arising out of or related to such Hazardous Materials,
(iii) any lawsuit or other proceeding brought or threatened, settlement reached
or governmental order or decree relating to such Hazardous Materials, and/or
(iv) complying or coming into compliance with all Hazardous Material Laws
(including the cost of any remediation or monitoring required in connection
therewith) or any other Requirement of Law INCLUDING, WITHOUT LIMITATION,
CLAIMS, DEMANDS, PENALTIES, FINES, LIABILITIES, SETTLEMENTS, DAMAGES, COSTS AND
EXPENSES IN ANY WAY OR TO THE EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT
ACT OR OMISSION OF ANY KIND BY AGENT, LENDERS OR THEIR AFFILIATES; provided,
however, that the Borrower shall have no obligations under this Section 13.5(c)
with respect to claims, demands, penalties, fines, liabilities, settlements,
damages, costs or expenses to the extent arising as a result of the gross
negligence or willful misconduct of the Agent or such Lender, as the case may
be. The obligations of Borrower under this Section 13.5(c) shall be in addition
to any and all other obligations and liabilities Borrower may have to Agent or
any of the Lenders at common law or pursuant to any other agreement.

         13.6 Notices.

         (a) Except as expressly provided otherwise in this Agreement (and
except as provided in clause (b) below), all notices and other communications

properly addressed, shall be deemed given two (2) Business Days after the date
on which it was sent, unless it is actually received sooner by the named
addressee; and any notice, if transmitted by facsimile, shall be deemed given

not be required to, take any action on the basis of any notice given to it by
telephone, but the giver of any such notice shall promptly confirm such notice
in writing, by facsimile, and such notice will not be deemed to have been
received until such confirmation is deemed received in accordance with the
provisions of this Section set forth above. If such telephonic notice conflicts
with any such confirmation, the terms of such telephonic notice shall control.
Any notice given by the Agent or any Lender to the Borrower shall be deemed to
be a notice to all of the Borrowers.

         (b) Notices and other communications provided to any the Agent and the
Lenders party hereto under this Agreement or any other Loan Document may be
delivered or furnished by electronic communication (including email and Internet
or intranet websites) pursuant to procedures approved by the Agent. The Agent or
the Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications (including email and
Internet or intranet websites) pursuant to procedures approved by it. Unless
otherwise agreed to in a writing by and among the parties to a particular
communication, (i) notices and other communications sent to an email address
shall be deemed received upon the sender's receipt of an acknowledgment from the
intended recipient (such as by the "return receipt requested" function, return
email, or other written acknowledgment) and (ii) notices and other
communications posted to an Internet or intranet website shall be deemed
received upon the deemed receipt by the intended recipient at its email address
as described in the foregoing clause (i) of notification that such notice or
other communication is available and identifying the website address therefore.

         13.7 Further Action. Borrower, from time to time, upon written request
of Agent will make, execute, acknowledge and deliver or cause to be made,
executed, acknowledged and delivered, all such further and additional
instruments, and take all such further action as may reasonably be required to
carry out the intent and purpose of this Agreement or the Loan Documents, and to
provide for Advances under and payment of the Notes, according to the intent and
purpose herein and therein expressed.

         13.8 Successors and Assigns; Participations; Assignments.

         (a) This Agreement shall be binding upon and shall inure to the benefit
of the Borrower and the Lenders and their respective successors and assigns.

         (b) The foregoing shall not authorize any assignment by Borrower of its
rights or duties hereunder, and, except as otherwise provided herein, no such
assignment shall be made (or be effective) without the prior written approval of
the Lenders.

         (c) No Lenders may at any time assign or grant participations in such
Lender's rights and obligations hereunder and under the other Loan Documents
except (i) by way of assignment to any Eligible Assignee in accordance with
clause (d) of this Section, (ii) by way of a participation in accordance with
the provisions of clause (e) of this Section or (iii) by way of a pledge or
assignment of a security interest subject to the restrictions of clause (f) of
this Section (and any other attempted assignment or transfer by any Lender shall
be deemed to be null and void).

                                       64

         (d) Each assignment by a Lender of all or any portion of its rights and
obligations hereunder and under the other Loan Documents, shall be subject to
the following terms and conditions:

                  (i)      each such assignment shall be made on a pro rata
                           basis, and shall be in a minimum amount of the lesser
                           of (x) One Million Dollars ($1,000,000) or such
                           lesser amount as the Agent shall agree and (y) the
                           entire remaining amount of assigning Lender'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 Lender's aggregate
                           interest in the Revolving Credit (and participations
                           in any outstanding Letters of Credit) be less than
                           $5,000,000; and

                  (ii)     the parties to any assignment shall execute and
                           deliver to Agent an Assignment Agreement
                           substantially (as determined by Agent) in the form
                           attached hereto as Exhibit E (with appropriate
                           insertions acceptable to Agent), together with a
                           processing and recordation fee in the amount, if any,
                           required as set forth in the Assignment Agreement
                           (provided however that such Lender need not deliver
                           an Assignment Agreement in connection with
                           assignments to such Lender's Affiliates or to a
                           Federal Reserve Bank).

Until the Assignment Agreement becomes effective in accordance with its terms,
and Agent has confirmed that the assignment satisfies the requirements of this
Section 13.8, the Borrower and the Agent shall be entitled to continue to deal
solely and directly with the assigning Lender in connection with the interest so
assigned. From and after the effective date of each Assignment Agreement that
satisfies the requirements of this Section 13.8, the assignee thereunder shall
be deemed to be a party to this Agreement, such assignee shall have the rights
and obligations of a Lender 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) and the assigning Lender shall
relinquish its rights and be released from its obligations under this Agreement
and the other Loan Documents.

         Upon request, Borrower shall execute and deliver to the Agent, new
Note(s) payable to the order of the assignee in an amount equal to the amount
assigned to the assigning Lender pursuant to such Assignment Agreement, and with
respect to the portion of the Indebtedness retained by the assigning Lender, to
the extent applicable, new Note(s) payable to the order of the assigning Lender
in an amount equal to the amount retained by such Lender hereunder. The Agent,
the Lenders and the Borrower acknowledge and agree that any such new Note(s)
shall be given in renewal and replacement of the Notes issued to the assigning
lender prior to such assignment and shall not effect or constitute a novation or
discharge of the Indebtedness evidenced by such prior Note, and each such new
Note may contain a provision confirming such agreement.

         (e) The Borrower and the Agent acknowledge that each of the Lenders may
at any time and from time to time, subject to the terms and conditions hereof,
grant participations in such Lender's rights and obligations hereunder (on a pro
rata basis only) and under the other Loan Documents to any Person (other than a
natural person or to Borrower or any of Borrower's Affiliates or Subsidiaries);
provided that any participation permitted hereunder shall comply with all
applicable laws and shall be subject to a participation agreement that
incorporates the following restrictions:

                  (i)      such Lender shall remain the holder of its Notes
                           hereunder (if such Notes are issued), notwithstanding
                           any such participation;

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

                                       65
<PAGE>

                  (iii)    such Lender shall retain the sole right and
                           responsibility to enforce the obligations of the
                           Borrowers relating to the Notes and the other Loan
                           Documents, including, without limitation, the right
                           to proceed against any Guarantors, or cause the 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
                           (unless such participant is an Affiliate of such
                           Lender), except for those matters covered by Section
                           13.10(a) through (e) hereof (provided that a
                           participant may exercise approval rights over such
                           matters only on an indirect basis, acting through
                           such Lender and the Borrowers, Agent and the other
                           Lenders may continue to deal directly with such
                           Lender in connection with such Lender's rights and
                           duties hereunder). Notwithstanding the foregoing,
                           however, in the case of any participation granted by
                           any Lender hereunder, the participant shall not have
                           any rights under this Agreement or any of the other
                           Loan Documents against the Agent, any other Lender or
                           any Borrower; provided, however that the participant
                           may have rights against such Lender in respect of
                           such participation as may be set forth in the
                           applicable participation agreement and all amounts
                           payable by the Borrowers hereunder shall be
                           determined as if such Lender had not sold such
                           participation. Each such participant shall be
                           entitled to the benefits of Article 11 of this
                           Agreement to the same extent as if it were a Lender
                           and had acquired its interest by assignment pursuant
                           to clause (d) of this Section, provided that no
                           participant shall be entitled to receive any greater
                           amount pursuant to such the provisions of Article 11
                           than the issuing Lender would have been entitled to
                           receive in respect of the amount of the participation
                           transferred by such issuing Lender to such
                           participant had no such transfer occurred and each
                           such participant shall also be entitled to the
                           benefits of Section 9.6 hereof as though it were a
                           Lender, provided that such participant agrees to be
                           subject to Section 10.3 hereof as though it were a
                           Lender.

         (f) Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement (including its Notes, if
any) to secure obligations of such Lender, including any pledge or assignment to
secure obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or
substitute any such pledge or assignee for such Lender as a party hereto.

         (g) The Agent shall maintain at its principal office a copy of each
Assignment Agreement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Lenders, the Percentages of such
Lenders and the principal amount of each type of Advance owing to each such
Lender from time to time. The entries in the Register shall be conclusive
evidence, absent manifest error, and the Borrower, the Agent, and the Lenders
may treat each Person whose name is recorded in the Register as the owner of the
Advances recorded therein for all purposes of this Agreement. The Register shall
be available for inspection by the Borrower or any Lender upon reasonable notice
to the Agent and a copy of such information shall be provided to any such party
on their prior written request. The Agent shall give prompt written notice to
the Borrower of the making of any entry in the Register or any change in such
entry.

         (h) Borrower authorizes each Lender to disclose to any prospective
assignee or participant which has satisfied the requirements hereunder, any and
all financial information in such Lender's possession concerning the Borrowers
which has been delivered to such Lender pursuant to this Agreement, provided
that each such prospective assignee or participant shall execute a
confidentiality agreement consistent with the terms of Section 13.11 hereof or
shall otherwise agree to be bound by the terms thereof.

         (i) 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

                                       66
<PAGE>

participants permitted hereunder and thereunder any benefit or any legal or
equitable right, remedy or other claim under this Agreement, the Notes or the
other Loan Documents.

         13.9 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.
Loan Documents may be transmitted and/or signed by facsimile. The effectiveness
of any such documents and signatures shall, subject to applicable law, have the
same force and effect as manually-signed originals and shall be binding on all
Borrowers, the Agent and the Lenders. The Agent may also require that any such
documents and signatures be confirmed by a manually-signed original thereof;
provided, however, that the failure to request or deliver the same shall not
limit the effectiveness of any facsimile document or signature.

         13.10 Amendment and Waiver. No amendment or waiver of any provision of
this Agreement or any other Loan Document, nor consent to any departure by any
Borrower therefrom, shall in any event be effective unless the same shall be in
writing and signed by the Agent and the Majority Lenders (or by the Agent at the
written request of the Majority Lenders) or, if this Agreement expressly so
requires with respect to the subject matter thereof, by all Lenders (and, with
respect to any amendments to this Agreement or the other Loan Documents, by any
Borrower or the Guarantors that 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 the Lender or Lenders affected thereby,
do any of the following: (a) increase any Lender's commitments hereunder, (b)
reduce the principal of, or interest on, any outstanding Indebtedness or any
Fees or other amounts payable hereunder, (c) postpone any date fixed for any
payment of principal of, or interest on, any outstanding Indebtedness or any
Fees or other amounts payable hereunder, (d) except as expressly permitted
hereunder or under the Collateral Documents, release all or substantially all of
the Collateral or release any material guaranty provided by any Person in favor
of Agent and the Lenders, provided however that Agent shall be entitled, without
notice to or any further action or consent of the Lenders, to release any
Collateral which any Borrower is permitted to sell, assign or otherwise transfer
in compliance with this Agreement or the other Loan Documents or release any
guaranty to the extent expressly permitted in this Agreement or any of the other
Loan Documents (whether in connection with the sale, transfer or other
disposition of the applicable Guarantor or otherwise), (e) terminate or modify
any indemnity provided to the Lenders hereunder or under the other Loan
Documents, except as shall be otherwise expressly provided in this Agreement or
any other Loan Document, or (f) change the definitions of "Revolving Credit
Percentage", "Interest Periods", "Majority Lenders", Section 10.2 hereof or this
Section 13.10; provided, further, that notwithstanding the foregoing, the
Revolving Credit Maturity Date may be postponed or extended only with the
consent of all of the Revolving Credit Lenders; provided further, that no
amendment, waiver or consent shall, unless in a writing signed by the Swing Line
Lender, 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 a writing signed by the Agent
affect the rights or duties of the Agent under this Agreement or any other Loan
Document. All references in this Agreement to "Lenders" or "the Lenders" shall
refer to all Lenders, unless expressly stated to refer to Majority Lenders (or
the like).

         The Agent shall, upon the written request of the Borrower, execute and
deliver to the Borrowers such documents as may be necessary to evidence (1) the
release of any Lien granted to or held by the Agent upon any Collateral: (a)
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; (b) which constitutes property (including, without limitation, Equity
Interests in any Person) sold or to be sold or disposed of as part of or in
connection with any disposition (whether by sale, by merger or by any other form
of transaction and including the property of any Subsidiary that is disposed of
as permitted hereby) permitted in accordance with the terms of this Agreement;
(c) which constitutes property in which a Borrower owned no interest at the time
the Lien was granted or at any time thereafter; or (d) if approved, authorized
or ratified in writing by the Majority Lenders, or all the Lenders, as the case
may be, as provided in this Section 13.10; or (2) the release of any Person from
its obligations under the Loan Documents (including without limitation the

                                       67
<PAGE>

Guaranty) if all of the Equity Interests of such Person that were held by a
Borrower are sold or otherwise transferred to any transferee other than Borrower
or a Subsidiary of Borrower as part of or in connection with any disposition
(whether by sale, by merger or by any other form of transaction) permitted in
accordance with the terms of this Agreement; provided that (i) Agent shall not
be required to execute any such release or subordination agreement under clauses
(1) or (2) above on terms which, in the Agent's opinion, would expose the Agent
to liability or create any obligation or entail any consequence other than the
release of such Liens without recourse or warranty or such release shall not in
any manner discharge, affect or impair the Indebtedness or any Liens upon any
Collateral retained by any Borrower, including (without limitation) the proceeds
of the sale or other disposition, all of which shall constitute and remain part
of the Collateral.

         13.11 Confidentiality. Each Lender agrees that it will not disclose
without the prior consent of the Borrower (other than to its employees, its
Subsidiaries, another Lender, an Affiliate of a Lender or to its auditors or
counsel) any information with respect to the Borrowers which is furnished
pursuant to this Agreement or any of the other Loan Documents; provided that any
Lender may disclose any such information (a) as has become generally available
to the public or has been lawfully obtained by such Lender from any third party
under no duty of confidentiality to any Borrower, (b) as may be required or
appropriate in any report, statement or testimony submitted to, or in respect to
any inquiry, by, any municipal, state or federal regulatory body having or
claiming to have jurisdiction over such Lender, including the Board of Governors
of the Federal Reserve System of the United States, the Office of the
Comptroller of the Currency or the Federal Deposit Insurance Corporation or
similar organizations (whether in the United States or elsewhere) or their
successors, (c) as may be required or appropriate in respect to any summons or
subpoena or in connection with any litigation, (d) in order to comply with any
law, order, regulation, ruling or other requirement of law applicable to such
Lender, and (e) to any prospective assignee or participant in accordance with
Section 13.8(g) hereof.

         13.12 Substitution of Lenders. If (a) any Lender has failed to fund its
Revolving Credit Percentage of any Revolving Credit Advance, or to fund a
Revolving Credit Advance to repay a Swing Line Advance or any Reimbursement
Obligations, (b) the obligation of any Lender to make Eurodollar-based Advances
has been suspended pursuant to Section 11.3 or 11.4, (c) any Lender has demanded
compensation under Section 3.4(d), 11.1, 11.5 or 11.6 or (d) any Lender has not
approved an amendment, waiver or other modification of this Agreement, if such
amendment or waiver has been approved by the Majority Lenders and the consent of
such Lender is required (in each case, an "Affected Lender"), then the Agent or
the Borrower shall have the right to make written demand on the Affected Lender
(with a copy to the Borrower in the case of a demand by the Agent or with a copy
to the Agent in the case of a demand by the Borrower) to assign and the Affected
Lender shall assign, to one or more financial institutions that comply with the
provisions of Section 13.8 hereof (the "Purchasing Lender" or "Purchasing
Lenders") to purchase the Advances of the Revolving Credit Loan and/or Swing
Line of such Affected Lender (including, without limitation, its participating
interests in outstanding Swing Line Advances and Letters of Credit) and assume
the commitment of the Affected Lender to extend credit under the Revolving
Credit (including without limitation its obligation to purchase participations
interest in Swing Line Advances and Letters of Credit) under this Agreement. The
Affected Lender shall be obligated to sell its Advances of the Revolving Credit
Loan and/or Swing Line Advances and assign its commitment to extend credit under
the Revolving Credit (including without limitation its obligations to purchase
participations in Swing Line Advances and Letters of Credit) to such Purchasing
Lender or Purchasing Lenders within ten (10) days after receiving notice from
the Borrower 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, the Borrower shall pay to the Affected Lender all fees
accrued for its account hereunder to but excluding the date of such sale, plus,
if demanded by the Affected Lender within ten (10) Business Days after such
sale, (i) the amount of any compensation which would be due to the Affected
Lender under Section 11.1 if the Borrower had prepaid the outstanding
Eurodollar-based Advances of the Affected Lender on the date of such sale and
(ii) any additional compensation accrued for its account under Sections 3.4(d),
11.5 and 11.6 to but excluding said date. Upon such sale, the Purchasing Lender
or Purchasing Lenders shall assume the Affected Lender's commitment, and the
Affected Lender shall be released from its obligations hereunder to a

                                       68
<PAGE>

corresponding extent. If any Purchasing Lender is not already one of the
Lenders, the Affected Lender, as assignor, such Purchasing Lender, as assignee,
the Borrower and the Agent, shall enter into an Assignment Agreement pursuant to
Section 13.8 hereof, whereupon such Purchasing Lender shall be a Lender party to
this Agreement, shall be deemed to be an assignee hereunder and shall have all
the rights and obligations of a Lender with a Revolving Credit Percentage equal
to its ratable share of the then applicable Revolving Credit Aggregate
Commitment and the applicable Percentages of the Term Loan of the Affected
Lender. In connection with any assignment pursuant to this Section 13.12, the
Borrower or the Purchasing Lender shall pay to the Agent the administrative fee
for processing such assignment referred to in Section 13.8.

         13.13 Withholding Taxes. If any Lender is not a "united states person"
within the meaning of Section 7701(a)(30) of the Internal Revenue Code, such
Lender shall promptly (but in any event prior to the initial payment of interest
hereunder or prior to its accepting any assignment under Section 13.8 hereof, as
applicable) deliver to the Agent two executed copies of (i) Internal Revenue
Service Form W-8BEN or any successor form specifying the applicable tax treaty
between the United States and the jurisdiction of such Lender's domicile which
provides for the exemption from withholding on interest payments to such Lender,
(ii) Internal Revenue Service Form W-8ECI or any successor form evidencing that
the income to be received by such Lender hereunder is effectively connected with
the conduct of a trade or business in the United States or (iii) other evidence
satisfactory to the Agent that such Lender is exempt from United States income
tax withholding with respect to such income; provided, however, that such Lender
shall not be required to deliver to Agent the aforesaid forms or other evidence
with respect to Advances to Borrower, if such Lender has assigned its entire
interest hereunder (including its Revolving Credit Commitment Amount, any
outstanding Advances hereunder and participations in Letters of Credit issued
hereunder and any Notes issued to it by Borrower), to an Affiliate which is
incorporated under the laws of the United States or a state thereof, and so
notifies the Agent. Such Lender 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 Lender
hereunder were subject to United States income tax withholding when made, such
Lender 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. In addition, from time to time upon the reasonable request and the sole
expense of Borrower, each Lender and the Agent shall (to the extent it is able
to do so based upon applicable facts and circumstances), complete and provide
Borrower with such forms, certificates or other documents as may be reasonably
necessary to allow Borrower, as applicable, to make any payment under this
Agreement or the other Loan Documents without any withholding for or on the
account of any tax under Section 10.1(d) hereof (or with such withholding at a
reduced rate), provided that the execution and delivery of such forms,

and the applicable Lender to comply with the USA Patriot Act.

         13.17 Complete Agreement; Conflicts. This Agreement, the Notes (if

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.

         THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

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

         13.20 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.

         13.21 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

                  (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. 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 Borrower, 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 Lender 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;

                           (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 Lender 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 Lender 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 Lenders' 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,

                                       71

                           protest, and all other notices whatsoever other than
                           notices expressly provided for in this Agreement;
                           (iv) any claim or defense based on an election of
                           remedies; and (v) 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.

                  (d)      No delay on any of the Lenders 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 Lenders 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
                           Lenders permitted hereunder shall in any way affect
                           or impair any such Lenders' rights or any Borrower's
                           Indebtedness under this Agreement.

                  (e)      Each of the Borrowers hereby represents and warrants
                           to each of the Lenders that it now has and will
                           continue to have independent means of obtaining
                           information concerning the Borrowers' affairs,
                           financial condition and business. Lenders 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
                           Lenders' possession.

                  (f)      Each of the Borrowers represents and warrants (i)
                           that the business operations of the Borrowers are
                           interrelated and that the business operations of the
                           Borrowers complement one another, and such entities
                           have a common business purpose, 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 and the other
                           credit facilities extended hereunder will directly or
                           indirectly benefit the Borrowers hereunder, severally
                           and jointly, regardless of which Borrower 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 Lenders 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 Borrower's respective
                           obligations hereunder unenforceable or avoidable or
                           subject to recovery under Applicable Insolvency Laws.
                           To the extent any payment actually made hereunder
                           exceeds the limitation contained in this Section
                           13.22(h), 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 Lenders upon
                           demand by such Borrowers. The foregoing proviso is
                           intended solely to preserve the rights of the Agent
                           and the Lenders 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 13.22(h) that would not otherwise be
                           available under Applicable Insolvency Laws.

of the Borrowers and the existence of the Indebtedness in general advertisements
and trade publications.

         13.24 Reliance on and Survival of Various Provisions. All terms,

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 any Borrower in connection with this Agreement or any of the Loan
Documents shall be deemed to have been relied upon by the Lenders,
notwithstanding any investigation heretofore or hereafter made by any Lender or
on such Lender's behalf, and those covenants and agreements of the Borrower set
forth in Section 13.5 hereof (together with any other indemnities of any
Borrower contained elsewhere in this Agreement or in any of the other Loan
Documents) and of Lenders set forth in Section 12.7 hereof shall survive the
repayment in full of the Indebtedness and the termination of any commitment to
extend credit.
