3.  PROCEDURE

         3.1 Lender will keep records of all Obligations and Collateral that is
in its possession, appropriately marked to show the interest of Participant
therein, and Participant or its designees may inspect or copy same at
reasonable times during normal business hours. Lender will, from time to time,
promptly following the execution thereof, furnish Participant with copies of
future Transaction Agreements relating to Term Loan B, and with such additional
information as Lender may have and may deem appropriate to provide to
Participant with respect to such Transaction Agreements; provided, however,
that Lender shall not be liable to Participant for any damages resulting from
Lender's failure to provide such copies of such future Transaction Agreements
or such information, except if Lender's failure is the result of gross
negligence or willful misconduct.

         3.2 During the term of this Agreement, Lender will deliver monthly
statements to Participant showing the status of the Term Loan B Transactions
and the Obligations as of the last day of the preceding month and the activity
during such preceding month. Any accounting rendered by Lender to Participant
presumptively shall be deemed correct and binding unless Participant notifies
Lender by certified mail, return receipt requested, to the contrary, within 30
days after the date when each such accounting is mailed or otherwise delivered
to Participant.

         3.3 Participant acknowledges that Lender has not made and does not
make any representations or warranties, express or implied, as to Borrower's
financial condition, or with respect to the validity, enforceability,
collectibility, priority, or perfection of any of the Transaction Agreements,
the Transactions, or the Collateral, and that Participant is fully familiar
with and has made its own independent evaluation and determination thereof.
Lender represents and warrants to Participant that Lender is the legal owner of
the interest in Term Loan B being conveyed hereunder, that Lender has the full
right, power and authority to assign, transfer and convey such interest, and
that such interest is being transferred free and clear of any claims, liens or
interests of any third parties. Participant expressly acknowledges: (a) that,
except as expressly provided hereinabove, Lender has not made any
representations or warranties to it of any sort whatsoever and that no act by
Lender hereafter taken, including any review of the affairs of Borrower or of
any guarantors, shall be deemed to constitute any representation or warranty by
Lender to Participant; (b) that Participant will continue to make its own
independent investigation of the financial condition and affairs, and its own
appraisal of the creditworthiness, of Borrower or any guarantors in connection
with the Transactions; and (c) that Lender shall have no duty or
responsibility, either initially or on a continuing basis, to provide
Participant with any credit or other information except as expressly provided
for herein.

                                       4

         3.4 Because Participant's Investment is a "last-out" participation, it
is expected that Participant's Investment will remain fully funded at all times
prior to the Term Loan B Maturity Date (as such term is defined in the Loan
Agreement). Except as provided in Section 5.1 hereof in the event that (i)
Lender shall have accelerated the maturity of the Obligations based on
Borrower's default under the Transaction Agreements, or (ii) the Obligations
shall have matured in accordance with their terms and not have been repaid in
full, Participant hereby agrees with Lender that all amounts received by
Lender, whether by Collections or otherwise, shall be applied to Borrower's
loan account with Lender at such time and in such manner as is provided in the
Transaction Agreements, and shall be applied to the repayment of the
Obligations as follows:

           (a) first, to the repayment of all Obligations then due and payable
to Lender (including, without limitation, all accrued and unpaid interest with
respect to Obligations other than Term Loan B then due and payable to Lender
and all accrued and unpaid Foothill Expenses (as defined in the Loan Agreement)
then due and payable to Lender (other than Participant Expenses), but excluding
Obligations in respect of Term Loan B);

           (b) second, to the repayment of all accrued interest with respect to
Term Loan B then due and payable with respect to Term Loan B;

           (c) third, to the repayment of all accrued and unpaid fees
(including, without limitation, the Amendment Fee) and all Participant Expenses
in each case then due and payable with respect to Term Loan B;

           (d) fourth, to the repayment of all outstanding Obligations (other
than Obligations in respect of Term Loan B); and

           (f) fifth, to the repayment of all unpaid principal of, or other
Obligations in respect of, Term Loan B.

           All payments hereunder shall be made by wire transfer according to
wiring instructions delivered by each party to the other party hereto.

         3.5 (a) Participant's Investment hereunder shall accrue interest in
accordance with the terms and conditions of the Loan Agreement. Except as
provided in Section 5.1 hereof in the event that (i) Lender shall have
accelerated the maturity of the Obligations based on Borrower's default under
the Transaction Agreements, or (ii) the Obligations shall have matured in
accordance with their terms and not have been repaid in full, Lender agrees
that, upon receipt by Lender of payments in respect of Obligations then due and
payable with respect to Term Loan B, all such amounts with respect to
Participant's Investment hereunder shall be promptly paid to Participant in
United States Dollars, in accordance with this Section 3.5. Under any
circumstances in which Participant shall not be entitled to receive payments
with respect to Participant's Investment as herein provided, then Participant's
right to the return of Participant's Investment thereafter shall be subject to
Section 5.1 hereof without regard to Lender's declaration of Borrower's loan
account to be in liquidation pursuant to Section 5.1 hereof.

                                       5
<PAGE>   6

                  (b) Participant shall not be entitled to any compensation
based upon any float, or any similar charges provided under the Transaction
Agreements, nor shall Participant share in the Closing Facility Fee, any
Anniversary Facility Fee, any Unused Line Fee, any Servicing Fees, or any other
fees paid by Borrower to Lender, except for the Amendment Fee as provided
herein. Participant shall not share in any financial examination, documentation
or appraisal fees paid to Lender. Participant shall not share in any recovery
by Lender of out-of-pocket expenses incurred by Lender and reimbursable by
Borrower except to the extent that such expenses are "extraordinary expenses"
(as hereinbelow defined) with respect to which Participant theretofore paid to
Lender its pro-rata share (based on Participant's Ratable Share of the
Obligations) thereof.

                  (c) Participant shall be entitled to the entire portion of
the Amendment Fee (in the amount of $225,000) that is due and payable on
November 1, 2000 (except to the extent such portion of the Amendment Fee shall
not be payable by Borrower under the terms of the Eleventh Amendment), as and
when such Portion of the Amendment Fee shall be due and payable by Borrower.

                  (d) Participant shall be entitled, if and to the extent that
such amounts are received in cash by Lender, to all Participant Expenses paid
or incurred by Participant and which are subject to reimbursement by Borrower
in accordance with the provisions of the Eleventh Amendment or the Loan
Agreement as amended thereby.

         3.6 In the event that Lender is required, for any reason, to refund or
repay to Borrower or any other person all or any portion of any payment
previously made to Lender with respect to Term Loan B and which has been paid
to Participant and applied to reduce Participant's Investment therein,
Participant shall remit to Lender such amount as was previously paid to
Participant that is required to be so refunded or repaid by Lender, and
Participant's Investment shall be increased accordingly.

         3.7 Lender shall not have, and does not assume, any liability to
Participant for the repayment of Participant's Investment or interest and fees
thereon, or reimbursement of expenses in connection therewith, to the extent
that such funds are not received from Borrower or collected from the proceeds
of the Collateral, except for losses occasioned by Lender's gross negligence or
willful misconduct.

         3.8 Lender shall bear all costs and expenses of managing and servicing
the Transactions except for extraordinary expenses, which shall be borne by
Lender and Participant pro-rata (based upon Participant's Ratable Share of the
Obligations), and for which Participant shall reimburse Lender upon demand for
Participant's pro-rata share (based upon Participant's Ratable Share of the
Obligations) thereof. The term "extraordinary expenses" shall consist of any
reasonable out-of-pocket costs and expenses, and shall include, but not be
limited to, reasonable attorneys fees and disbursements, court costs and
reasonable fees of any outside agency, incurred in connection with the
enforcement of any of Lender's rights and remedies after the date of this
Agreement against Borrower or any guarantors, arising under the Transaction
Agreements, or with regard to any of the Collateral, or in defending any action
or opposing any claim asserted at any time by Borrower or any of its
stockholders or any guarantors or any receiver or trustee in

                                       6
<PAGE>   7

bankruptcy, or by any other party against Lender or Participant caused by any
alleged claim of usury, ultra vires act or invalidity, any alleged preferential
or fraudulent transfer, or any other claim (other than a claim resulting from
Lender's gross negligence or willful misconduct) in connection with the
Transactions or the Collateral or any recovery on account of such claim;
provided, however, that Participant will be liable only if such fees or costs
are incurred on or after the Eleventh Amendment Closing Date, or such claims
relate to Transactions occurring on or after the Eleventh Amendment Closing
Date and prior to the effective date of termination of this Agreement, or such
fees or costs are incurred or arise while, or relate to Transactions or
Collateral occurring or existing while, Borrower's loan account shall be in a
liquidation declared prior to the effective date of termination of this
Agreement. Lender promptly shall provide Participant with notice of the
assertion of any action or claim described in the immediately preceding
sentence; provided, however, that Lender shall not be liable to Participant,
nor shall Participant be relieved of its obligations under this Section 3.8,
unless Lender fails to provide such notice willfully or as a result of gross
negligence. Extraordinary expenses shall not include any expenses of ordinary
overhead or ordinary payments made to clerical personnel or executives of
Lender. Participant also shall reimburse Lender, on demand, for Participant's
pro-rata share (based upon Participant's Ratable Share of the Obligations) of
all amounts paid by Lender in settlement or compromise of any such claim or
action (subject to the same provisos as set forth above), except in the event,
and in such case then except only to the extent, that such claim or action
arose out of the gross negligence or willful misconduct of Lender. Any such
settlement or compromise shall require the prior written approval of
Participant (which approval shall not be unreasonably withheld, conditioned, or
delayed). If Borrower's loan account is not in liquidation under Section 5.1,
prior to requiring Participant to pay its share of any extraordinary expenses,
Lender first shall make reasonable endeavors to charge same to Borrower and
collect same from Borrower, provided that if no revolving Advances are
available to Borrower under the Transaction Agreements and Borrower fails or
refuses to pay same promptly upon demand by Lender, Lender may require
Participant to pay its share without having to first declare Borrower's loan
account in liquidation, commence legal proceedings against Borrower, or proceed
against Collateral. If and to the extent that Participant defaults in its
obligations to make any payment to Lender as required pursuant to this Section
3.8, such amount shall be deducted from the amount of Participant's Investment
hereunder.

         3.9 If Participant defaults in its obligations to make any payment to
Lender as required hereunder, including without limitation the failure to make
payment of any extraordinary expenses (as that term is defined in Section 3.8
hereof), within 15 Business Days of the date on which notice of Participant's
failure to make such payment is received by Participant, then the amount of any
such payment, including without limitation any such unpaid extraordinary
expenses, shall be deducted from the amounts otherwise payable to Participant
in repayment of Participant's Investment or from any other amounts to which it
might otherwise be entitled hereunder. All amounts that would have been
distributed to Participant before the preceding sentence will instead be
retained by Lender and applied to reduce amounts advanced by Lender under the
Transaction Agreements in connection with any such unpaid extraordinary
expenses for which Participant has failed to fund its pro rata share (based
upon Participant's Ratable Share of the Obligations).

4.  MANAGEMENT

         4.1 (a) Participant acknowledges that its interest in Term Loan B,
together with the Agreements, Transactions, Obligations, Collateral, and
Collections in respect of Term Loan B, is derivative of Lender's interest in
the same, and that, as between Participant and Lender, Lender shall have the
sole right and authority in all respects to make decisions with respect to the
same, to deal with Borrower with respect to the same, and to administer
(including making legal claims with respect to the same and appearing in court
in connection with the enforcement of, or on account of, such claims) Lender's
and Participant's interest in the same. All of the Obligations and other
Transactions shall be made and conducted in Lender's name, and all of the
Collateral and Collections shall be held by or on behalf of Lender in Lender's
name. Lender shall have the right to administer the Transaction Agreements, to
perform and enforce the terms thereof, and to exercise all privileges and
rights exercisable or enforceable by Lender thereunder, according to Lender's
discretion and in the exercise of its normal business judgment. Lender hereby
expressly appoints Participant as Lender's agent for the purpose of perfecting
Lender's security interest in any of the Collateral that may at any time come
into the possession of Participant. Lender shall have the continuing and sole
right to enter into and agree to amendments, waivers, modifications, and
releases with respect to the Transaction Agreements, the Transactions, and the
Collateral. In the event of a bankruptcy filing by Borrower or against
Borrower, and in the event of any other insolvency proceeding involving
Borrower, Lender, and not Participant, shall have the sole right and authority
to file a claim on account of the interest of Lender and Participant in Term
Loan B, or the Agreements, Transactions, Obligations, Collateral, and
Collections in respect of Term Loan B, to appear in bankruptcy court or other
court on account of the same, and to otherwise take such action as Lender may
deem appropriate in order to collect on the same. Lender shall not be liable to
Participant for any action taken or omitted or for any error in judgment,
except for its own gross negligence or willful misconduct.

                  (b) Anything contained herein to the contrary
notwithstanding, for so long as there shall be any outstanding Obligations with
respect to Term Loan B, Lender shall not, without the prior written consent of
Participant, (i) agree to any amendment, modification or waiver of any of the
rate of interest, principal amount, or maturity of Term Loan B, or the
Amendment Fee, or (ii) make any additional Advances under and as defined in the
Loan Agreement in excess of the aggregate amount of $40,000,000 principal at
any one time outstanding.

                  (c) Anything contained herein to the contrary
notwithstanding, if at any time all Obligations of Borrower to Lender (other
than with respect to Term Loan B) have been paid in full in cash (or as
otherwise agreed by Lender in its discretion) and there shall remain any
outstanding Obligations with respect to Term Loan B, Lender shall assign to
Participant or Participant's designee, without any representation, recourse, or
warranty whatsoever, except as expressly set forth below in this paragraph,
Participant's Percentage in Lender's right, title, and interest with respect to
the Transactions and the Transaction Agreements and all security interests
granted therein with respect to Term Loan B, at no expense to Participant other
than the reimbursement by Participant (to the extent not paid by Borrower) of
the reasonable out-of-pocket expenses of Lender and its legal counsel in
connection with documenting and effecting

                                       8
<PAGE>   9

such assignment, such documentation and assignment to be in such form as Lender
and Participant shall mutually agree, whereupon Lender shall be relieved from
any further duties, obligations, or liabilities to Participant pursuant to this
Agreement. In connection with any assignment by Lender pursuant to this
paragraph, Lender shall be deemed to have warranted to the assignee that Lender
is the legal owner of the interests being assigned, that Lender has the full
right, power and authority to assign, transfer and convey such interests, and
that such interests are being transferred free and clear of any claims, liens
or interests of any third parties (other than Participant or Participant's
designee).

                  (d) Anything contained herein to the contrary
notwithstanding, for so long as there shall be any outstanding Obligations with
respect to Term Loan B, in all matters in respect of the portion of the
Amendment Fee payable to Participant (including, without limitation, the form
of payment thereof), and with respect to any extension of the Term Loan B
Maturity Date to a date not later than October 1, 2003, Lender shall at all
times act pursuant to the instructions of Participant.

                  (e) Anything contained herein to the contrary
notwithstanding, for so long as there shall be any outstanding Obligations with
respect to Term Loan B, Lender shall not release any lien of Lender in any
material portion of the Collateral securing Term Loan B except in accordance
with the Transaction Documents and in connection with the receipt by Borrower
or Lender of proceeds in amount not less than the fair market value of all
assets subject to such lien release, such proceeds to be applied to the
Obligations.

         4.2 Subject to the last sentence of Section 4.1 hereof, Lender shall
exercise the same care and discretion in managing and servicing the Obligations
(including, without limitation, Term Loan B) and other Transactions, in making
Collections in connection therewith, and in entering into any compromise or
settlement with Borrower in connection therewith, as it would ordinarily
exercise with respect to loans for which it has no participant. To the extent
of Participant's interests hereunder, Lender is not, and shall not under any
circumstances be deemed to be, a fiduciary for Participant in administering and
servicing the Transaction Agreements or in any other capacity. Nothing
contained herein shall confer upon either Lender or Participant any proprietary
interest in, or subject either of them to any liability for or with respect to,
the business, assets, profits, losses, or obligations of the other, except only
as to the Obligations and other Transactions to the extent of the participation
hereby created.

         4.3 Participant shall not sell, pledge, assign, sub-participate, or
otherwise transfer all or any part of its interest hereunder to any third
person without Lender's prior written consent. Lender may further participate
or otherwise transfer or assign its interest in the Obligations, the
Collateral, the Collections, or the Transactions to any third person at any
time (in any such case a "Sale") without the consent of participant; provided,
however, that should Lender offer to make any such Sale to any third person,
(i) notwithstanding any such Sales, Lender shall at all times retain the right
to vote or otherwise control any such third party's share with respect to any
right of any such third party's share to consent to any amendment,
modification, waiver or consent under the Transaction Agreements, and (ii) any
such Sale shall be made subject to Participant's rights and Lender's
obligations under this Agreement.

                                       9
<PAGE>   10

         4.4 All payments with respect to the Obligations (including, without
limitation, any payment by way of setoff, banker's lien, counterclaim,
realization on Collateral or otherwise) received by Participant at any time,
from any source other than Lender as provided in this Agreement, shall be
immediately forwarded to Lender for application pursuant to the terms of this
Agreement; provided that, if Lender has outright assigned the Term Loan B to
Participant, this Section 4.4 shall not apply to payments received by
Participant with respect to the Term Loan B from and after the effectiveness of
such assignment.

         4.5 In the event a voluntary or involuntary bankruptcy case is
commenced by or against Borrower, and provided that Lender has not outright
assigned the Term Loan B to Participant, Lender shall file a proof of claim in
such bankruptcy case with respect to the Term Loan B (which may be separate
from the proof of claim filed with respect to the other Obligations) and Lender
shall, following the final and full payment of all other Obligations other than
the Term Loan B as provided in this Agreement, remit to Participant any
property or other distribution received by Lender on account of such claim with
respect to the Term Loan B. Notwithstanding the foregoing, in the event of such
bankruptcy case and provided that Lender has not outright assigned the Term
Loan B to Participant, subject to Lender's duties set forth in Section 4.2 of
this Agreement, Participant agrees that Lender shall have no liability to
Participant for, and Participant waives any claim it may hereafter have against
Lender arising out of, (a) Lender's consent to the use of cash collateral
pursuant to Section 363 of the United States Bankruptcy Code (Title 11 U.S.C.
101 et seq., as amended from time to time, the "Bankruptcy Code"), (b) Lender's
agreement to extend additional credit to Borrower, as debtor-in-possession, or
to a trustee, pursuant to Section 364 of the Bankruptcy Code, (c) pursuant to
the provisions of this Agreement, Lender's application of payments received in
such case, including the application to Obligations accruing after the
commencement of such case (including without limitation interest, fees, costs
and other charges, whether or not allowed as claims in such case), and (d)
Lender's election made pursuant to Section 1111(b)(2) of the Bankruptcy Code.

5.  LIQUIDATION

         5.1 If at any time (i) Lender shall have accelerated the maturity of
the Obligations based on Borrower's default under the Transaction Agreements,
or (ii) the Obligations shall have matured in accordance with their terms and
not have been repaid in full, Lender may, at its option, declare Borrower's
loan account in liquidation. Thereafter, notwithstanding the provisions of
Section 3.4 hereof, all Collections received shall be applied:

                  (a) first, to the payment of all of Lender's share of all
accrued and unpaid expenses to the extent earned or due and payable in
accordance with the Loan Agreement (including the reimbursement of
extraordinary expenses, financial examination expenses, and loan documentation
review charges, and including any such expenses that, but for the provision of
the Bankruptcy Code would have accrued or otherwise been payable) in respect of
the Obligations other than Term Loan B owing by Borrower, until paid in full in
cash;

                  (b) Second, to the payment of all of Lender's share of all
accrued and unpaid interest and any unpaid fees to the extent earned or due and
payable in accordance with the Loan

                                      10

Agreement (including any interest or unpaid fees that, but for the provision of
the Bankruptcy Code would have accrued or otherwise been payable) in respect of
the Obligations other than Term Loan B, until paid in full in cash;

                  (c) Third, to the payment of all of Lender's share of the
unpaid Obligations other than Term Loan B, until paid in full in cash;

                  (d) Fourth, to the extent that Lender has funded any part of
Term Loan B, to the payment of all of Lender's share of all accrued and unpaid
expenses to the extent earned or due and payable in accordance with the Loan
Agreement (including the reimbursement of extraordinary expenses, financial
examination expenses, and loan documentation review charges, and including any
such expenses that, but for the provision of the Bankruptcy Code would have
accrued or otherwise been payable) in respect of the Obligations consisting of
Term Loan B, until paid in full in cash;

                  (e) Fifth, to the extent that Lender has funded any part of
Term Loan B, to the payment of all of Lender's share of all accrued and unpaid
interest and any unpaid fees to the extent earned or due and payable in
accordance with the Loan Agreement (including any interest or unpaid fees that,
but for the provision of the Bankruptcy Code would have accrued or otherwise
been payable) in respect of the Obligations consisting of Term Loan B, until
paid in full in cash;

                  (f) Sixth, to the extent that Lender has funded any part of
Term Loan B, to the payment of all of Lender's share of the Obligations
consisting of Term Loan B, until paid in full in cash;

                  (g) Seventh, to the payment of all of Participant's share of
all accrued and unpaid expenses to the extent earned or due and payable in
accordance with the Loan Agreement (including the reimbursement of
extraordinary expenses, and including any such expenses that, but for the
provision of the Bankruptcy Code would have accrued or otherwise been payable)
in respect of the Obligations consisting of Term Loan B, until paid in full in
cash;

                  (h) Eighth, to the payment of all of Participant's share of
all accrued and unpaid interest and any unpaid fees to the extent earned or due
and payable in accordance with the Loan Agreement (including any interest or
unpaid fees that, but for the provision of the Bankruptcy Code would have
accrued or otherwise been payable) in respect of Obligations consisting of Term
Loan B, until paid in full in cash; and

                  (i) Ninth, to the payment of Participant's share of the
Obligations consisting of Term Loan B.

                  Participant understands that Participant's participation is a
last-out participation as to Participant's Investment, subject only to
Participant's right to receive any amounts due to Participant pursuant to
Section 3.5 when Borrower's Obligations have not been accelerated.

                                      11

6.  TERMINATION

         6.1 Except during any period when Borrower's loan account shall be in
liquidation, this Agreement and the participation hereby created shall
terminate on the full and final repayment in cash of all Obligations of
Borrower to Lender under the Transaction Agreements in accordance with their
terms and payment in full in cash of Participant's investment in Term Loan B
and all other amounts due to Participant hereunder. Any termination hereunder
notwithstanding, Participant's obligations to make payments under the
provisions of Section 3.6 hereof arising during the effectiveness of this
Agreement shall survive any such termination of this Agreement. If, prior to
the effective date of such termination, Lender declares Borrower's loan account
to be in liquidation, then the provisions of Section 5.1 hereof shall govern
notwithstanding the provisions of this Section 6, and the Collections shall
thereafter be distributed pursuant to the provisions of Section 5.1, based on
the amount of Participant's Investment, as of the date the liquidation is
declared by Lender.

         6.2 In the event that the Obligations shall have matured in accordance
with their terms and not have been repaid in full, anything contained herein to
the contrary notwithstanding, Lender shall have the option on or after such
date to repay to Participant the outstanding balance of Participant's
Investment, plus Participant's accrued interest and fees (including, without
limitation, the Amendment Fee), plus any unreimbursed Participant Expenses due
and payable pursuant to the Eleventh Amendment or the Loan Agreement as amended
thereby, calculated pursuant to Section 3.5 hereof, to the date of purchase.
Upon repayment in full to Participant, each party shall thereupon be relieved
of any liability to the other party in connection herewith, except that the
provisions of Section 3.6 hereof shall survive after termination. In the event
that Lender shall not exercise its option to repay Participant pursuant to this
Section 6.2, all Obligations and other Transactions in existence or entered
into on or after the maturity of the Obligations in accordance with their terms
shall be accounted for as if Borrower's loan account were in liquidation under
Section 5.1. If Borrower's loan account is in or shall thereafter go into
liquidation, the Collections shall thereafter be distributed pursuant to the
provisions of Section 5.1, based on the amount of Participant's Investment, as
of the date the liquidation is declared by Lender.

7.  GENERAL

successors, and permitted assigns, (b) shall be governed, construed, and
interpreted in all respects in accordance with the laws of the State of
California, and (c) may not be modified, amended, terminated, or otherwise
changed orally or by any course of dealing or in any manner except by an

         7.3 Each of the parties hereby expressly submits and consents in
advance to the non-exclusive jurisdiction of the Superior Court of the State of
California in the County of Los Angeles and jurisdiction of the United States
District Court for the Central District of California in any action or
proceeding commenced by the other in such court with reference to any claim or
dispute between the parties pertaining directly or indirectly to this Agreement
or to any matter arising therefrom. Each of the parties hereby waives the right
to trial by jury in any such action or proceeding, and personal service of any
summons, complaint, writ, process, or other papers may be by registered or
certified mail addressed to the party to be served at the address to which
notices are to be sent pursuant to Section 7.1 hereof.

         7.4 If any action at law or equity is brought to enforce or interpret
the provisions of this Agreement, the prevailing party shall be entitled to
recover its reasonable attorneys fees, which may be determined by the court in
the same action or in a separate action brought for that purpose, in addition
to any other relief to which that party may be entitled.

         7.5 No term or provision contained in this Agreement, and no other
agreement between the parties hereto, is intended to be, or shall it be
construed to be, the formation of a partnership or joint venture between Lender
and Participant.

         7.6 It is understood and agreed that Lender and Participant, or any
affiliate of either thereof may, from time to time, lend money to or otherwise
generally engage in any business with Borrower and any affiliate of Borrower.

         7.7 This Agreement and the duties and obligations contained herein
shall be solely for the benefit of the parties hereto, their affiliates, and
future participants; no third party shall have any rights hereunder as a third
party beneficiary or otherwise.

         7.8 To the extent that any payment of any amount by Lender to
Participant is deferred as the result of a liquidation pursuant to Section 5.1
hereof, Participant's ultimate right to collect such amount, or to attempt to
collect such amount, from Borrower (subject to Lender's prior right to be
repaid its share of the Obligations in full as more particularly provided
hereinabove) shall not be deemed to have been waived or forfeited vis-a-vis
Borrower, but merely deferred to the prior rights of Lender.

         7.9 Unless the context of this Agreement clearly requires otherwise,
references to the plural include the singular, references to the singular
include the plural, the term "including" is not limiting, and the term "or"
has, except where otherwise indicated, the inclusive meaning represented by the
phrase "and/or." The words "hereof," "herein," "hereby," "hereunder," and
similar terms in this Agreement refer to this Agreement as a whole and not to
any particular provision of this Agreement. Section, subsection, clause,
schedule, and exhibit references are to this Agreement unless otherwise
specified. Any reference in this Agreement to the Loan Agreement or any of the
Loan Documents shall include all alterations, amendments, changes, extensions,
modifications, renewals, replacements, substitutions, and supplements, thereto
and thereof, as applicable.

         7.10 This Agreement may be executed in any number of counterparts and
by different parties on separate counterparts, each of which, when executed and
delivered, shall be deemed to be an original, and all of which, when taken
together, shall constitute but one and the same Agreement. Delivery of an
executed counterpart of this Agreement by telefacsimile shall be equally as
effective as delivery of a manually executed counterpart of this Agreement. Any
party delivering an executed counterpart of this Agreement by telefacsimile
also shall deliver a manually executed counterpart of this Agreement but the
failure to deliver a manually executed counterpart shall not affect the
validity, enforceability, and binding effect of this Agreement.

         7.11 Participant is not purchasing Participant's Investment on behalf
of one or more employee benefit plans, or with proceeds which constitute "plan
assets," as defined in the Employee Retirement Income Security Act of 1974, as
amended, and the rules and regulations promulgated thereunder.

         7.12 (a) If Lender is sued or threatened with suit by a receiver or
trustee in any bankruptcy or other insolvency proceeding involving Borrower or
any other Obligor (i) on account of any alleged preferential or fraudulent
transfer received or alleged to have been received, directly or indirectly,
from Borrower or any other such Person, to the extent attributable to Term Loan
B or Participant's Investment, or (ii) relating to the equitable subordination
of the Obligations or the recharacterization of any of the Obligations as
equity, to the extent attributable to Term Loan B or the Participant's
Investment, then Participant shall (A) indemnify, defend and hold Lender
harmless from any such suit, claim or action and (B) repay or reimburse Lender
for all expenses, costs and reasonable attorneys fees paid or incurred, or
payments made by Lender, in connection therewith. To the extent that any
amounts previously paid in respect of the Obligations are recovered from
Lender, such amounts shall be reinstated as part of the Obligations, repayable
in accordance with the priorities established herein and in the Loan Agreement.

              (b) Participant hereby indemnifies Lender against, and agrees
to hold Lender harmless from, any and all claims, demands, actions,
controversies, suits, liabilities, losses, damages, judgments, awards, costs
and expenses (collectively, "Losses"), including, without limitation, all
reasonable attorneys fees and disbursements and reasonable time charges of
in-house counsel of Lender, arising by reason of or resulting from (i) any
breach of Participant's representations, warranties or covenants contained
herein, (ii) any Losses described in Section 7.12(a) above, (iii) any Losses
directly arising from the making, administration, collection or enforcement of
the Term Loan B or any interest in Collateral securing the Term Loan B, or that
would not have occurred but for the Participant's Investment or the entering
into of this Agreement, in each case save and except for any such Losses
resulting from the gross negligence or willful misconduct of Lender, (iv) any
sale, assignment or transfer of, or grant of a subparticipation in, all or any
part of the Participant's Investment, or (v) Lender's following any direction
or request of Participant with respect to the Participant's Investment.
Participant's obligation to indemnify Lender under this Agreement, including,
without limitation, under Section 7.12(a) hereof, will continue notwithstanding
any termination or expiration of this

                                      14

Agreement or the Loan Agreement, or any outright assignment of the Term Loan B
from Lender to Participant.
