          (a)  Interest Rate.  Except as provided in Section 2.6(c), below, all
                                                     --------------
Advances shall bear interest on the Daily Balance as follows:

               (i)  each LIBOR Rate Loan shall bear interest at a per annum rate
     equal to the LIBOR Rate plus the Applicable LIBOR Rate Margin; and

               (ii) all other Obligations shall bear interest at a per annum
     rate equal to the Reference Rate plus the Applicable Reference Rate Margin.

          (b)  Intentionally Omitted.

          (c)  Default Rate.  Upon the occurrence and during the continuation of
an Event of Default, all Obligations shall bear interest on the Daily Balance at
a per annum rate equal to three percentage points above the rate set forth in
Section 2.6(a)(ii).
------------------

          (d)  Intentionally Omitted.

          (e)  Payments.  Interest in respect of Reference Rate Loans payable
hereunder shall be due and payable, in arrears, on the first day of each month
during the term hereof. Interest in respect of each LIBOR Rate Loan shall be due
and payable, in arrears, on the last day of the applicable Interest Period.
Borrowers hereby authorize Foothill, at its option, without prior notice to
Borrowers, to charge such interest, all Foothill Expenses (as and when
incurred), the fees and charges provided for in Section 2.11 (as and when
                                                ------------
accrued or incurred), and all other payments as and when due and payable under
any Loan Document to Borrowers' Loan Account, which amounts shall thereafter
constitute Advances hereunder and shall accrue

                                       20
<PAGE>

interest at the rate then applicable to Advances that are Reference Rate Loans
hereunder. Any interest not paid when due shall be compounded by being charged
to Borrowers' Loan Account and shall thereafter constitute Advances hereunder
and shall accrue interest at the rate then applicable to Advances that are
Reference Rate Loans hereunder.

          (f)  Computation.  The Reference Rate as of the date of this Agreement
is 8.00% per annum. In the event the Reference Rate is changed from time to time
hereafter, the applicable rate of interest hereunder automatically and
immediately shall be increased or decreased by an amount equal to such change in
the Reference Rate. All interest and fees chargeable under the Loan Documents
shall be computed on the basis of a 360 day year for the actual number of days
elapsed.

          (g)  Intent to Limit Charges to Maximum Lawful Rate. In no event shall
the interest rate or rates payable under this Agreement, plus any other amounts
paid in connection herewith, exceed the highest rate permissible under any law
that a court of competent jurisdiction shall, in a final determination, deem
applicable. Borrowers and Foothill, in executing and delivering this Agreement,
intend legally to agree upon the rate or rates of interest and manner of payment
stated within it; provided, however, that, anything contained herein to the
                  --------  -------
contrary notwithstanding, if said rate or rates of interest or manner of payment
exceeds the maximum allowable under applicable law, then, ipso facto as of the
                                                          ---- -----
date of this Agreement, Borrowers are and shall be liable only for the payment
of such maximum as allowed by law, and payment received from Borrowers in excess
of such legal maximum, whenever received, shall be applied to reduce the
principal balance of the Obligations to the extent of such excess.

     2.7  Collection of Accounts.  Borrowers shall at all times maintain Lockbox
Agreements and, immediately after the Closing Date, shall instruct all Account
Debtors with respect to the Accounts, General Intangibles, and Negotiable
Collateral of Borrower to remit all Collections in respect thereof in accordance
                                ---
with such Lockbox Agreements. Borrowers, Foothill, and the Lockbox Banks shall
enter into the Lockbox Agreements, which among other things shall provide for
the opening of a Lockbox Account for the deposit of Collections at a Lockbox
Bank. Borrowers agree that all Collections and other amounts received by any
Borrower from any Account Debtor or any other source immediately upon receipt
shall be deposited into a Lockbox Account. No Lockbox Agreement or arrangement
contemplated thereby shall be modified by Borrowers without the prior written
consent of Foothill. Upon the terms and subject to the conditions set forth in
the Lockbox Agreements, Foothill shall the right at any time to require that all
amounts received in a Lockbox Account be wired each Business Day into an account
(the "Foothill Account") maintained by Foothill at a depositary selected by
Foothill. In the absence of such a requirement, amounts received in a Lockbox
Account may be transferred to an account of either Borrower.

      2.8 Crediting Payments; Application of Collections.  The receipt of any
Collections by Foothill (whether from transfers to Foothill by the Lockbox Banks
pursuant to the Lockbox Agreements or otherwise) immediately shall be applied
provisionally to reduce the Obligations outstanding under Section 2.1, but shall
                                                          -----------
not be considered a payment on account unless such Collection item is a wire
transfer of immediately available federal funds and is made to the Foothill
Account or unless and until such Collection item is honored when presented for
payment. From and after the Closing Date, Foothill shall be entitled to charge
Borrowers for one

                                       21
<PAGE>

Business Day of "clearance" or "float" at the rate set forth in Section
                                                                -------
2.6(a)(ii) or Section 2.6(c), as applicable, on all Collections (regardless of
----------    --------------
whether forwarded by the Lockbox Banks to Foothill, whether provisionally
applied to reduce the Obligations under Section 2.1, or otherwise). This across-
                                        -----------
the-board one Business Day clearance or float charge on all Collections is
acknowledged by the parties to constitute an integral aspect of the pricing of
Foothill's financing of Borrowers, and shall apply irrespective of the
characterization of whether receipts are owned by any Borrower or Foothill, and
whether or not there are any outstanding Advances, the effect of such clearance
or float charge being the equivalent of charging one Business Day of interest on
such Collections. Should any Collection item not be honored when presented for
payment, then Borrowers shall be deemed not to have made such payment, and
interest shall be recalculated accordingly. Anything to the contrary contained
herein notwithstanding, any Collection item shall be deemed received by Foothill
only if it is received into the Foothill Account on a Business Day on or before
11:00 a.m. California time. If any Collection item is received into the Foothill
Account on a non-Business Day or after 11:00 a.m. California time on a Business
Day, it shall be deemed to have been received by Foothill as of the opening of
business on the immediately following Business Day.

     2.9  Designated Account.  Foothill is authorized to make the Advances under
this Agreement based upon telephonic or other instructions received from anyone
purporting to be an Authorized Person, or without instructions if pursuant to
Section 2.6(e). Administrative Borrower agrees to establish and maintain the
--------------
Designated Account with the Designated Account Bank for the purpose of receiving
the proceeds of the Advances requested by Borrowers and made by Foothill
hereunder. Unless otherwise agreed by Foothill and Administrative Borrower, any
Advance requested by Borrowers and made by Foothill hereunder shall be made to
the Designated Account.

     2.10 Maintenance of Loan Account; Statements of Obligations. Foothill shall
maintain an account on its books in the name of Borrowers (the "Loan Account")
on which Borrowers will be charged with all Advances made by Foothill to
Borrowers or for Borrowers' account, and with all other payment Obligations
hereunder or under the other Loan Documents, including, accrued interest and
Foothill Expenses. In accordance with Section 2.8, the Loan Account will be
                                      -----------
credited with all payments received by Foothill from Borrowers or for Borrowers'
account, including all amounts received in the Foothill Account from any Lockbox
Bank. Foothill shall render statements regarding the Loan Account to
Administrative Borrower, including principal, interest, fees, and including an
itemization of all charges and expenses constituting Foothill Expenses owing,
and such statements shall be conclusively presumed to be correct and accurate
and constitute an account stated between Borrowers and Foothill unless, within
30 days after receipt thereof by Administrative Borrower, Administrative
Borrower shall deliver to Foothill written objection thereto describing the
error or errors contained in any such statements.

     2.11 Fees.  Borrowers shall pay to Foothill the following fees:

          (a)  Closing Fee.  On the Closing Date, a closing fee of $225,000;

                                       22
<PAGE>

          (b)  Unused Line Fee.  On the first day of each month during the term
of this Agreement, an unused line fee in an amount equal to 0.375% per annum
times the Average Unused Portion of the Maximum Amount;

          (c)  Intentionally Omitted;

          (d)  Financial Examination, Documentation, and Appraisal Fees.
Foothill's customary fee of $750 per day per examiner, plus out-of-pocket
expenses for each financial analysis and examination (i.e., audits) of Borrowers
performed by personnel employed by Foothill; provided, however, that so long as
no Event of Default has occurred and is continuing, Borrower shall only be
obligated to pay for the first four audits conducted by or on behalf of Foothill
during each calendar year (any audit conducted while an Event of Default exists
shall not be counted when calculating the number of audits conducted during a
calendar year); Foothill's out-of-pocket expenses for each appraisal of the
Collateral; and, the actual charges paid or incurred by Foothill if it elects to
employ the services of one or more third Persons to perform such financial
analyses and examinations (i.e., audits) of Borrowers or to appraise the
Collateral; and, a one time fee of $5,000, plus out of pocket expenses, for
setting up electronic reporting by Borrowers; and

          (e)  Servicing Fee. For each month, a monthly servicing fee in the
amount of $3,000 payable in arrears.

     2.12 LIBOR Options

          (a)  Interest and Interest Payment Dates. In lieu of having interest
charged at the rate based upon the Reference Rate, Borrowers shall have the
option (the "LIBOR Option") to have interest on all or a portion of the Advances
             ------------
be charged at the LIBOR Rate plus the Applicable LIBOR Rate Margin. Interest on
LIBOR Rate Loans shall be payable on the earliest of (i) the last day of the
Interest Period applicable thereto, (ii) the occurrence of an Event of Default
in consequence of which Foothill has elected to accelerate the maturity of the
Obligations, or (iii) termination of this Agreement pursuant to the terms
hereof. On the last day of each applicable Interest Period, unless
Administrative Borrower properly has exercised the LIBOR Option with respect
thereto, the interest rate applicable to such LIBOR Rate Loan automatically
shall convert to the rate of interest then applicable to Reference Rate Loans of
the same type hereunder. At any time that an Event of Default has occurred and
is continuing, Borrowers no longer shall have the option to request that
Advances bear interest at the LIBOR Rate and Foothill shall have the right to
convert the interest rate on all outstanding LIBOR Rate Loans to the rate then
applicable to Reference Rate Loans hereunder.

          (b)  LIBOR Election.

               (i)  Administrative Borrower may, at any time and from time to
time, so long as no Event of Default has occurred and is continuing, elect to
exercise the LIBOR Option by notifying Foothill prior to 11:00 a.m. (California
time) at least 3 Business Days prior to the commencement of the proposed
Interest Period (the "LIBOR Deadline"). Notice of Administrative Borrower's
                      --------------
election of the LIBOR Option for a permitted portion of the Advances and an
Interest Period pursuant to this Section shall be made by delivery to Foothill
of

                                       23
<PAGE>

a LIBOR Notice received by Foothill before the LIBOR Deadline, or by telephonic
notice received by Foothill before the LIBOR Deadline (to be confirmed by
delivery to Foothill of a LIBOR Notice received by Foothill prior to 5:00 p.m.
(California time) on the same day.

               (ii) Each LIBOR Notice shall be irrevocable and binding on
Borrowers. In connection with each LIBOR Rate Loan, each Borrower shall
indemnify, defend, and hold Foothill harmless against any loss, cost, or expense
incurred by Foothill as a result of (a) the payment of any principal of any
LIBOR Rate Loan other than on the last day of an Interest Period applicable
thereto (including as a result of an Event of Default), (b) the conversion of
any LIBOR Rate Loan other than on the last day of the Interest Period applicable
thereto, or (c) the failure to borrow, convert, continue or prepay any LIBOR
Rate Loan on the date specified in any LIBOR Notice delivered pursuant hereto
(such losses, costs, and expenses, collectively, "Funding Losses"). Funding
                                                  --------------
Losses shall, with respect to Foothill, be deemed to equal the amount determined
by Foothill to be the excess, if any, of (i) the amount of interest that would
have accrued on the principal amount of such LIBOR Rate Loan had such event not
occurred, at the LIBOR Rate that would have been applicable thereto, for the
period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue,
for the period that would have been the Interest Period therefor), minus (ii)
the amount of interest that would accrue on such principal amount for such
period at the interest rate which Foothill would be offered were it to be
offered, at the commencement of such period, Dollar deposits of a comparable
amount and period in the London interbank market. A certificate of Foothill
delivered to Administrative Borrower setting forth any amount or amounts that
Foothill is entitled to receive pursuant to this Section shall be conclusive
absent manifest error.

               (iii)  Borrowers shall have not more than 5 LIBOR Rate Loans in
effect at any given time. Borrowers only may exercise the LIBOR Option for LIBOR
Rate Loans of at least $1,000,000 and integral multiples of $500,000 in excess
thereof.

          (c)  Prepayments.  Borrowers may prepay LIBOR Rate Loans at any time;
provided, however, that in the event that LIBOR Rate Loans are prepaid on any
--------  -------
date that is not the last day of the Interest Period applicable thereto,
including as a result of any automatic prepayment through the required
application by Foothill of proceeds of Collections in accordance with Section
                                                                      -------
2.4(b) or for any other reason, including early termination of the term of this
------
Agreement or acceleration of the Obligations pursuant to the terms hereof, each
Borrower shall indemnify, defend, and hold Foothill and their Participants
harmless against any and all Funding Losses in accordance with clause (b) above.

          (d)  Special Provisions Applicable to LIBOR Rate.

               (i)  The LIBOR Rate may be adjusted by Foothill on a prospective
basis to take into account any additional or increased costs to Foothill of
maintaining or obtaining any eurodollar deposits or increased costs due to
changes in applicable law occurring subsequent to the commencement of the then
applicable Interest Period, including changes in tax laws (except changes of
general applicability in corporate income tax laws) and changes in the reserve
requirements imposed by the Board of Governors of the Federal Reserve System (or
any successor), excluding the Reserve Percentage, which additional or increased

                                       24
<PAGE>

costs would increase the cost of funding loans bearing interest at the LIBOR
Rate. In any such event, Foothill shall give Administrative Borrower notice of
such a determination and adjustment and, upon its receipt of the notice from
Foothill, Administrative Borrower may, by notice to Foothill (y) require
Foothill to furnish to Administrative Borrower a statement setting forth the
basis for adjusting such LIBOR Rate and the method for determining the amount of
such adjustment, or (z) repay the LIBOR Rate Loans with respect to which such
adjustment is made (together with any amounts due under clause (b)(ii) above).

               (ii) In the event that any change in market conditions or any
law, regulation, treaty, or directive, or any change therein or in the
interpretation of application thereof, shall at any time after the date hereof,
in the reasonable opinion of Foothill, make it unlawful or impractical for
Foothill to fund or maintain LIBOR Advances or to continue such funding or
maintaining, or to determine or charge interest rates at the LIBOR Rate,
Foothill shall give notice of such changed circumstances to Administrative
Borrower and (y) in the case of any LIBOR Rate Loans that are outstanding, the
date specified in Foothill's notice shall be deemed to be the last day of the
Interest Period of such LIBOR Rate Loans, and interest upon the LIBOR Rate Loans
of Foothill thereafter shall accrue interest at the rate then applicable to
Reference Rate Loans, and (z) Borrowers shall not be entitled to elect the LIBOR
Option until Foothill determines that it would no longer be unlawful or
impractical to do so.

          (e)  No Requirement of Matched Funding. Anything to the contrary
contained herein notwithstanding, neither Foothill, nor any of its Participants,
is required actually to acquire eurodollar deposits to fund or otherwise match
fund any Obligation as to which interest accrues at the LIBOR Rate. The
provisions of this Section shall apply as if Foothill or its Participants had
match funded any Obligation as to which interest is accruing at the LIBOR Rate
by acquiring eurodollar deposits for each Interest Period in the amount of the
LIBOR Rate Loans.

     2.13  Capital Requirements.  If, after the date hereof, Foothill determines
that (i) the adoption of or change in any law, rule, regulation or guideline
regarding capital requirements for banks or bank holding companies, or any
change in the interpretation or application thereof by any Governmental
Authority charged with the administration thereof, or (ii) compliance by
Foothill or its parent bank holding company with any guideline, request or
directive of any such entity regarding capital adequacy (whether or not having
the force of law), the effect of reducing the return on Foothill's or such
holding company's capital as a consequence of Foothill's obligations hereunder
to a level below that which Foothill or such holding company could have achieved
but for such adoption, change, or compliance (taking into consideration
Foothill's or such holding company's then existing policies with respect to
capital adequacy and assuming the full utilization of such entity's capital) by
any amount deemed by Foothill to be material, then Foothill may notify
Administrative Borrower thereof. Following receipt of such notice, Borrowers
agree to pay Foothill on demand the amount of such reduction of return of
capital as and when such reduction is determined, payable within 90 days after
presentation by Foothill of a statement in the amount and setting forth in
reasonable detail Foothill's calculation thereof and the assumptions upon which
such calculation was based (which statement shall be deemed true and correct
absent manifest error). In determining such amount, Foothill may use any
reasonable averaging and attribution methods.

        2.14  Joint and Several Liability of Borrowers.

              (a)  Each of Borrowers is accepting joint and several liability
hereunder and under the other Loan Documents in consideration of the financial
accommodations to be provided by Foothill under this Agreement, for the mutual
benefit, directly and indirectly, of each of Borrowers and in consideration of
the undertakings of the other Borrowers to accept joint and several liability
for the Obligations.

              (b)  Each of Borrowers, jointly and severally, hereby irrevocably
and unconditionally accepts, not merely as a surety but also as a co-debtor,
joint and several liability with the other Borrowers, with respect to the
payment and performance of all of the Obligations (including, without
limitation, any Obligations arising under this Section 2.14), it being the
                                               ------------
intention of the parties hereto that all the Obligations shall be the joint and
several obligations of each Person composing Borrowers without preferences or
distinction among them.

              (c)  If and to the extent that any of Borrowers shall fail to make
any payment with respect to any of the Obligations as and when due or to perform
any of the Obligations in accordance with the terms thereof, then in each such
event the other Persons composing Borrowers will make such payment with respect
to, or perform, such Obligation.

              (d)  The Obligations of each Person composing Borrowers under the
provisions of this Section 2.14 constitute the absolute and unconditional, full
recourse Obligations of each Person composing Borrowers enforceable against each
such Borrower to the full extent of its properties and assets, irrespective of
the validity, regularity or enforceability of this Agreement or any other
circumstances whatsoever.

              (e)  Except as otherwise expressly provided in this Agreement,
each Person composing Borrowers hereby waives notice of acceptance of its joint
and several liability, notice of any Advances under or pursuant to this
Agreement, notice of the occurrence of any Default, Event of Default, or of any
demand for any payment under this Agreement, notice of any action at any time
taken or omitted by Foothill under or in respect of any of the Obligations, any
requirement of diligence or to mitigate damages and, generally, to the extent
permitted by applicable law, all demands, notices and other formalities of every
kind in connection with this Agreement (except as otherwise provided in this
Agreement). Each Person composing Borrowers hereby assents to, and waives notice
of, any extension or postponement of the time for the payment of any of the
Obligations, the acceptance of any payment of any of the Obligations, the
acceptance of any partial payment thereon, any waiver, consent or other action
or acquiescence by Foothill at any time or times in respect of any default by
any Person composing Borrowers in the performance or satisfaction of any term,
covenant, condition or provision of this Agreement, any and all other
indulgences whatsoever by Foothill in respect of any of the Obligations, and the
taking, addition, substitution or release, in whole or in part, at any time or
times, of any security for any of the Obligations or the addition, substitution
or release, in whole or in part, of any Person composing Borrowers. Without
limiting the generality of the foregoing, each of Borrowers assents to any other
action or delay in acting or failure to act on the part of Foothill with respect
to the failure by any Person composing Borrowers to comply with any of its
respective Obligations, including, without limitation, any failure strictly or
diligently to assert any right or to pursue any remedy or to comply fully with
applicable laws or regulations

                                       26
<PAGE>

thereunder, which might, but for the provisions of this Section 2.14 afford
                                                        ------------
grounds for terminating, discharging or relieving any Person composing
Borrowers, in whole or in part, from any of its Obligations under this Section
                                                                       -------
2.14, it being the intention of each Person composing Borrowers that, so long as
----
any of the Obligations hereunder remain unsatisfied, the Obligations of such
Person composing Borrowers under this Section 2.14 shall not be discharged
                                      ------------
except by performance and then only to the extent of such performance. The
Obligations of each Person composing Borrowers under this Section 2.14 shall not
be diminished or rendered unenforceable by any winding up, reorganization,
arrangement, liquidation, reconstruction or similar proceeding with respect to
any Person composing Borrowers or Foothill. The joint and several liability of
the Persons composing Borrowers hereunder shall continue in full force and
effect notwithstanding any absorption, merger, amalgamation or any other change
whatsoever in the name, constitution or place of formation of any of the Persons
composing Borrowers or Foothill.

              (f)  Each Person composing Borrowers represents and warrants to
Foothill that such Borrower is currently informed of the financial condition of
Borrowers and of all other circumstances which a diligent inquiry would reveal
and which bear upon the risk of nonpayment of the Obligations. Each Person
composing Borrowers further represents and warrants to Foothill that such
Borrower has read and understands the terms and conditions of the Loan
Documents. Each Person composing Borrowers hereby covenants that such Borrower
will continue to keep informed of Borrowers' financial condition, the financial
condition of other guarantors, if any, and of all other circumstances which bear
upon the risk of nonpayment or nonperformance of the Obligations.

              (g)  The provisions of this Section 2.14 are made for the benefit
                                          ------------
of Foothill and respective successors and assigns, and may be enforced by it or
them from time to time against any or all of the Persons composing Borrowers as
often as occasion therefor may arise and without requirement on the part of
Foothill, successor, or assign first to marshal any of its or their claims or to
exercise any of its or their rights against any of the other Persons composing
Borrowers or to exhaust any remedies available to it or them against any of the
other Persons composing Borrowers or to resort to any other source or means of
obtaining payment of any of the Obligations hereunder or to elect any other
remedy. The provisions of this Section 2.14 shall remain in effect until all of
                               ------------
the Obligations shall have been paid in full or otherwise fully satisfied. If at
any time, any payment, or any part thereof, made in respect of any of the
Obligations, is rescinded or must otherwise be restored or returned by Foothill
upon the insolvency, bankruptcy or reorganization of any of the Persons
composing Borrowers, or otherwise, the provisions of this Section 2.14 will
                                                          ------------
forthwith be reinstated in effect, as though such payment had not been made.

              (h)  Each of the Persons composing Borrowers hereby agrees that it
will not enforce any of its rights of contribution or subrogation against the
other Persons composing Borrowers with respect to any liability incurred by it
hereunder or under any of the other Loan Documents, any payments made by it to
Foothill with respect to any of the Obligations or any collateral security
therefor until such time as all of the Obligations have been paid in full in
cash. Any claim which any Borrower may have against any other Borrower with
respect to any payments to Foothill hereunder or under any other Loan Documents
are hereby expressly made subordinate and junior in right of payment, without
limitation as to any increases in the Obligations arising hereunder or
thereunder, to the prior payment in full in cash of the

                                       27
<PAGE>

Obligations and, in the event of any insolvency, bankruptcy, receivership,
liquidation, reorganization or other similar proceeding under the laws of any
jurisdiction relating to any Borrower, its debts or its assets, whether
voluntary or involuntary, all such Obligations shall be paid in full in cash
before any payment or distribution of any character, whether in cash, securities
or other property, shall be made to any other Borrower therefor.

              (i)  Each of the Persons composing Borrowers hereby agrees that,
after the occurrence and during the continuance of any Default or Event of
Default, the payment of any amounts due with respect to the indebtedness owing
by any Borrower to any other Borrower is hereby subordinated to the prior
payment in full in cash of the Obligations. Each Borrower hereby agrees that

right to terminate its obligations under this Agreement immediately and without
notice upon the occurrence and during the continuation of an Event of Default.

Agreement, all Obligations immediately shall become due and payable without
notice or demand. No termination of this Agreement, however, shall relieve or

trademarks, discharges of security interests, and other similar discharge or

premium (the "Early Termination Premium") equal to 1% of the Maximum Amount for
each year or partial year of the unexpired term of this Agreement if such
termination occurs at any time thereafter other than on the Maturity Date;
provided that any such Early Termination Premium shall be eliminated if the
prepayment is made from the proceeds of a credit facility provided by a
commercial banking unit of Wells Fargo.

         3.7  Termination Upon Event of Default. If Foothill terminates this
Agreement upon the occurrence of an Event of Default, in view of the
impracticability and extreme difficulty of ascertaining actual damages and by
mutual agreement of the parties as to a reasonable calculation of Foothill's
lost profits as a result thereof, Borrower shall pay to Foothill upon the
effective date of such termination, a premium in an amount equal to the Early
Termination Premium. The Early Termination Premium shall be presumed to be the
amount of damages sustained by Foothill as the result of the early termination
and Borrower agrees that it is reasonable under the circumstances currently
existing. The Early Termination Premium provided for in this Section 3.7 shall
be deemed included in the Obligations.

interests in the Collateral shall attach to all Collateral without further act

been assigned to Foothill or that Foothill has a security interest therein, and

Account. Each Borrower agrees that it will hold in trust for Foothill, as

deliver said Collections to a Lockbox Bank or, if requested by Foothill, to
Foothill in their original form as received by the applicable Borrower.

         4.4  Delivery of Additional Documentation Required. At any time upon

extent permitted by applicable law, each Borrower authorizes Foothill to execute

office. In addition, on such periodic basis as Foothill shall require, Borrowers

period, (b) cause all patents, copyrights, and trademarks acquired or generated
by Borrowers that are not already the subject of a registration with the
appropriate filing office (or an application therefor diligently prosecuted) to
be registered with such appropriate filing office in a manner sufficient to
impart constructive notice of Borrowers' ownership thereof, and (c) cause to be
prepared, executed, and delivered to Foothill supplemental schedules to the
applicable Loan Documents to identify such patents, copyrights, and trademarks
as being subject to the security interests created thereunder.

         4.5  Power of Attorney. Each Borrower hereby irrevocably makes,
constitutes, and appoints Foothill (and any of Foothill's officers, employees,
or agents designated by Foothill) as such Borrower's true and lawful attorney,
with power to (a) if such Borrower refuses to, or fails timely to execute and
deliver any of the documents described in Section 4.4, sign the name of such

relating to the Collateral and forward all other mail to such Borrower, (f) at
any time that an Event of Default has occurred and is continuing, make, settle,

adjust disputes and claims respecting the Accounts, General Intangibles and
Negotiable Collateral directly with Account Debtors, for amounts and upon terms

and delivered any documents and releases that Foothill determines to be

the occurrence and during the continuance of a Default or Event of Default,
Lender may notify any securities intermediary to liquidate the applicable
Securities Account or any related Investment Property maintained or held thereby

properties or assets has ever been designated or identified in any manner
pursuant to any environmental protection statute as a Hazardous Materials
disposal site, or a candidate for closure pursuant to any environmental
protection statute. No Lien arising under any environmental protection statute

such depository, and (ii) the account numbers of the accounts maintained with
such depository.

         5.19  Complete Disclosure. All factual information (taken as a whole)
furnished by or on behalf of Borrowers in writing to Foothill (including all
information contained in the Schedules hereto or in the other Loan Documents)
for purposes of or in connection with this Agreement, the other Loan Documents
or any transaction contemplated herein or therein is, and all other such factual

insurance and such other insurance as Foothill shall specify, shall contain a
California Form 438BFU (NS) mortgagee endorsement, or an equivalent endorsement
satisfactory to Foothill, showing Foothill as sole loss payee thereof, and shall
contain a waiver of warranties. Every policy of insurance referred to in this
Section 6.9 shall contain an agreement by the insurer that it will not cancel
-----------
such policy except after 30 days prior written notice to Foothill and that any
loss payable thereunder shall be payable notwithstanding any act or negligence
of Borrowers or Foothill which might, absent such agreement, result in a
forfeiture of all or a part of such insurance payment and notwithstanding
occupancy or use of the Real Property for purposes more hazardous than permitted
by the terms of such policy. Borrowers shall deliver to Foothill certified
copies of such policies of insurance and evidence of the payment of all premiums
therefor.

insurance policies without any liability to Borrowers whatsoever in respect of
such adjustments. Any monies received as payment for any loss under any
insurance policy including the insurance policies mentioned above, shall be paid
over to Foothill to be applied at the option of Foothill either to the
prepayment of the Obligations without premium, in such order or manner as
Foothill may elect, or shall be disbursed to Administrative Borrower under stage
payment terms satisfactory to Foothill for application to the cost of repairs,
replacements, or restorations. All repairs, replacements, or restorations shall
be effected with reasonable promptness and shall be of a value at least equal to
the value of the items or property destroyed prior to such damage or
destruction. Upon the occurrence of an Event of Default, Foothill shall have the
right to apply all prepaid premiums to the payment of the Obligations in such
order or form as Foothill shall determine.

              (d)  Borrower shall not take out separate insurance concurrent in
form or contributing in the event of loss with that required to be maintained
under this Section 6.9, unless Foothill is included thereon as named insured
           -----------
with the loss payable to Foothill under a standard California 438BFU (NS)
Mortgagee endorsement, or its local equivalent. Administrative Borrower
immediately shall notify Foothill whenever such separate insurance is taken out,
specifying the insurer thereunder and full particulars as to the policies
evidencing the same, and originals of such policies immediately shall be
provided to Foothill.

applicable laws, rules, regulations, and orders of any governmental authority,

renewals, or extensions do not result in an increase in the aggregate principal
amount of the Indebtedness so refinanced, renewed, or extended, (iii) such

of the average weighted maturity of the Indebtedness so refinanced, renewed, or
extended, and (iv) to the extent that Indebtedness that is refinanced was
subordinated in right of payment to the Obligations, then the subordination
terms and conditions of the refinancing Indebtedness must be at least as
favorable to Foothill as those applicable to the refinanced Indebtedness.

        7.2  Liens.  Create, incur, assume, or permit to exist, directly or
indirectly, any Lien on or with respect to any of their property or assets, of
any kind, whether now owned or hereafter acquired, or any income or profits
therefrom, except for Permitted Liens (including Liens that are replacements of
Permitted Liens to the extent that the original Indebtedness is refinanced under
Section 7.1(d) and so long as the replacement Liens only encumber those assets

    9.  FOOTHILL'S RIGHTS AND REMEDIES.

        9.1  Rights and Remedies.  Upon the occurrence, and during the
continuation, of an Event of Default Foothill may, at its election, without
notice of its election and without demand, do any one or more of the following,
all of which are authorized by Borrowers:

             (a)  Declare all Obligations, whether evidenced by this Agreement,
by any of the other Loan Documents, or otherwise, immediately due and payable;

             (b)  Cease advancing money or extending credit to or for the
benefit of Borrowers under this Agreement, under any of the Loan Documents, or
under any other agreement between Borrowers and Foothill;

             (c)  Terminate this Agreement and any of the other Loan Documents
as to any future liability or obligation of Foothill, but without affecting any
of Foothill's Liens in the Collateral and without affecting the Obligations;

             (d)  Settle or adjust disputes and claims directly with Account
Debtors for amounts and upon terms which Foothill considers advisable, and in
such cases, Foothill will credit Loan Account with only the net amounts received
by Foothill in payment of such disputed Accounts after deducting all Foothill
Expenses incurred or expended in connection therewith;

             (e)  Cause Borrowers to hold all returned Inventory in trust for
Foothill, segregate all returned Inventory from all other property of Borrowers
or in Borrowers' possession and conspicuously label said returned Inventory as
the property of Foothill;

             (f)  Without notice to or demand upon any Borrower or any
guarantor, make such payments and do such acts as Foothill considers necessary
or reasonable to protect its

                                       50
<PAGE>

security interests in the Collateral. Each Borrower agrees to assemble the
Collateral if Foothill so requires, and to make the Collateral available to
Foothill as Foothill may designate. Each Borrower authorizes Foothill to enter
the premises where the Collateral is located, to take and maintain possession of
the Collateral, or any part of it, and to pay, purchase, contest, or compromise
any encumbrance, charge, or Lien that in Foothill's determination appears to
conflict with Foothill's Lien and to pay all expenses incurred in connection
therewith and to charge Borrowers' Loan Account therefor. With respect to any of
any Borrower's owned or leased premises, each Borrower hereby grants Foothill a
license to enter into possession of such premises and to occupy the same,
without charge, for up to 120 days in order to exercise any of Foothill's rights
or remedies provided herein, at law, in equity, or otherwise;

             (g)  Without notice to any Borrower (such notice being expressly
waived), and without constituting a retention of any collateral in satisfaction
of an obligation (within the meaning of Division 9 of the Code), set off and
apply to the Obligations any and all (i) balances and deposits of Borrowers held
by Foothill (including any amounts received in the Lockbox Accounts), or (ii)
indebtedness at any time owing to or for the credit or the account of any
Borrower held by Foothill;

             (h)  Hold, as cash collateral, any and all balances and deposits
of any Borrower held by Foothill, and any amounts received in the Lockbox
Accounts, to secure the full and final repayment of all of the Obligations;

             (i)  Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Foothill is hereby granted a license or other right to
use, without charge, each Borrower's labels, patents, copyrights, rights of use
of any name, trade secrets, trade names, trademarks, service marks, and
advertising matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling any
Collateral and each Borrower's rights under all licenses and all franchise
agreements shall inure to Foothill's benefit;

             (j)  Sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Borrowers' premises) as Foothill
determines is commercially reasonable. It is not necessary that the Collateral
be present at any such sale;

             (k)  Foothill shall give notice of the disposition of the
Collateral as follows:

                  (1)  Foothill shall give Administrative Borrower (for the
benefit of the applicable Borrower) a notice in writing of the time and place of
public sale, or, if the sale is a private sale or some other disposition other
than a public sale is to be made of the Collateral, then the time on or after
which the private sale or other disposition is to be made;

                  (2)  The notice shall be personally delivered or mailed,
postage prepaid, to Administrative Borrower as provided in Section 12, at least
                                                           ----------
five days before the date fixed for the sale, or at least five days before the
date on or after which the private sale or other disposition is to be made; no
notice needs to be given prior to the disposition of any portion of

                                       51
<PAGE>

the Collateral that is perishable or threatens to decline speedily in value or
that is of a type customarily sold on a recognized market.

                  (3)  If the sale is to be a public sale, Foothill also shall
give notice of the time and place by publishing a notice one time at least five
days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held;

             (l)  Foothill may credit bid and purchase at any public sale;

             (m)  Foothill may seek the appointment of a receiver or keeper to
take possession of all or any portion of the Collateral or to operate same and,
to the maximum extent permitted by law, may seek the appointment of such a
receiver without the requirement of prior notice or a hearing

             (n)  Foothill shall have all other rights and remedies available
to it at law or in equity pursuant to any other Loan Documents; and

             (o)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrowers. Any excess
will be returned, without interest and subject to the rights of third Persons,
by Foothill to Administrative Borrower (for the benefit of the applicable
Borrower).

        9.2  Remedies Cumulative.  Foothill's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Foothill shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Foothill of one
right or remedy shall be deemed an election, and no waiver by Foothill of any
Event of Default shall be deemed a continuing waiver. No delay by Foothill shall
constitute a waiver, election, or acquiescence by it.

    10.  TAXES AND EXPENSES.

         If any Borrower fails to pay any monies (whether taxes, assessments,
insurance premiums, or, in the case of leased properties or assets, rents or
other amounts payable under such leases) due to third Persons, or fails to make
any deposits or furnish any required proof of payment or deposit, all as
required under the terms of this Agreement, then, to the extent that Foothill
determines, in its Permitted Discretion, that such failure by any Borrower could
result in a Material Adverse Change, Foothill may do any or all of the following
without prior notice to any Borrower:  (a) make payment of the same or any part
thereof; (b) set up such reserves in Borrowers' Loan Account as Foothill deems
necessary to protect Foothill from the exposure created by such failure; or (c)
obtain and maintain insurance policies of the type described in Section 6.10,
                                                                ------------
and take any action with respect to such policies as Foothill deems prudent.
Any such amounts paid by Foothill shall constitute Foothill Expenses.  Any such
payments made by Foothill shall not constitute an agreement by Foothill to make
similar payments in the future or a waiver by Foothill of any Event of Default
under this Agreement.  Foothill need not inquire as to, or contest the validity
of, any such expense, tax, or Lien and the receipt of the usual official notice
for the payment thereof shall be conclusive evidence that the same was validly
due and owing.

                                       52
<PAGE>

    11. WAIVERS; INDEMNIFICATION.

        11.1  Demand; Protest; etc. Each Borrower waives demand, protest,
notice of protest, notice of default or dishonor, notice of payment and
nonpayment, nonpayment at maturity, release, compromise, settlement, extension,
or renewal of accounts, documents, instruments, chattel paper, and guarantees at
any time held by Foothill on which any Borrower may in any way be liable.

        11.2  Foothill's Liability for Collateral.  So long as Foothill
complies with its obligations, if any, under the Code, Foothill shall not in any
way or manner be liable or responsible for: (a) the safekeeping of the
Collateral; (b) any loss or damage thereto occurring or arising in any manner or
fashion from any cause; (c) any diminution in the value thereof; or (d) any act
or default of any carrier, warehouseman, bailee, forwarding agency, or other
Person. All risk of loss, damage, or destruction of the Collateral shall be
borne by Borrowers.

        11.3  Indemnification.  Borrower shall pay, indemnify, defend, and hold
Foothill, each Participant, and each of their respective officers, directors,
employees, counsel, agents, and attorneys-in-fact (each, an "Indemnified
Person") harmless (to the fullest extent permitted by law) from and against any
and all claims, demands, suits, actions, investigations, proceedings, and
damages, and all reasonable attorneys fees and disbursements and other costs and
expenses actually incurred in connection therewith (as and when they are
incurred and irrespective of whether suit is brought), at any time asserted
against, imposed upon, or incurred by any of them in connection with or as a
result of or related to the execution, delivery, enforcement, performance, and
administration of this Agreement and any other Loan Documents or the
transactions contemplated herein or therein, and with respect to any
investigation, litigation, or proceeding related to this Agreement, any other
Loan Document, or the use of the proceeds of the credit provided hereunder
(irrespective of whether any Indemnified Person is a party thereto), or any act,
omission, event or circumstance in any manner related thereto (all the
foregoing, collectively, the "Indemnified Liabilities"). The foregoing to the
contrary notwithstanding, Borrowers shall have no obligation to any Indemnified
Person under this Section 11.3 with respect to any Indemnified Liability that
                  ------------
a court of competent jurisdiction finally determines to have resulted from the
gross negligence or willful misconduct of such Indemnified Person. This
provision shall survive the termination of this Agreement and the repayment of
the Obligations. If any Indemnified Person makes any payment to any other
Indemnified Person with respect to an Indemnified Liability as to which
Borrowers were required to indemnify the Indemnified Person receiving such
payment, the Indemnified Person making such payment is entitled to be
indemnified and reimbursed by Borrowers with respect thereto.

    12.  NOTICES.

         Unless otherwise provided in this Agreement, all notices or demands by
any party relating to this Agreement or any other Loan Document shall be in

which may be sent by first-class mail, postage prepaid) shall be personally

receipt requested), overnight courier, electronic mail, or telefacsimile to the

    14. ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS

        14.1  Assignments and Participations

              (a)  Foothill may assign and delegate to one or more assignees
(each an "Assignee") all, or any ratable part of all, of the Obligations and the
         ---------
other rights and obligations of Foothill hereunder and under the other Loan
Documents; provided, however, that Borrowers may continue to deal solely and
           --------  -------
directly with Foothill in connection with the interest so assigned to an
Assignee until (i) written notice of such assignment, together with payment
instructions, addresses, and related information with respect to the Assignee,
have been given to Administrative Borrower by Foothill and the Assignee an
appropriate assignment and acceptance agreement.

              (b)  From and after the date that Foothill provides
Administrative Borrower with such written notice and executed assignment and
acceptance agreement, (i) the Assignee thereunder shall be a party hereto and,
to the extent that rights and obligations

                                       55
<PAGE>

hereunder have been assigned to it pursuant to such assignment and acceptance
agreement, shall have the assigned and delegated rights and obligations of
Foothill under the Loan Documents, and (ii) Foothill shall, to the extent that
rights and obligations hereunder and under the other Loan Documents have been
assigned and delegated by it pursuant to such assignment and acceptance
agreement, relinquish its rights (except with respect to Section 11.3 hereof)
                                                         ------------
and be released from its obligations under this Agreement (and in the case of an
assignment and acceptance agreement covering all or the remaining portion of
Foothill's rights and obligations under this Agreement and the other Loan
Documents, Foothill shall cease to be a party hereto and thereto), and such
assignment shall affect a novation between Borrowers and the Assignee.

              (c)  Immediately upon Borrower's receipt of such fully executed
assignment and acceptance agreement, this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to reflect the addition
of the Assignee and the resulting adjustment of the rights and duties of
Foothill arising therefrom.

              (d)  Foothill may at any time sell to one or more commercial
banks, financial institutions, or other Persons not Affiliates of Foothill (a
"Participant") participating interests in Obligations and the other rights and
 -----------
interests of Foothill hereunder and under the other Loan Documents; provided,
                                                                    --------
however, that (i) Foothill shall remain the "Foothill" for all purposes of this
-------
Agreement and the other Loan Documents and the Participant receiving the
participating interest in the Obligations and the other rights and interests of
Foothill hereunder shall not constitute a "Foothill" hereunder or under the
other Loan Documents and Foothill's obligations under this Agreement shall
remain unchanged, (ii) Foothill shall remain solely responsible for the
performance of such obligations, (iii) Borrowers and Foothill shall continue to
deal solely and directly with each other in connection with Foothill's rights
and obligations under this Agreement and the other Loan Documents, (iv) Foothill
shall not transfer or grant any participating interest under which the
Participant has the right to approve any amendment to, or any consent or waiver
with respect to, this Agreement or any other Loan Document, except to the extent
such amendment to, or consent or waiver with respect to this Agreement or of any
other Loan Document would (A) extend the final maturity date of the Obligations
hereunder in which such Participant is participating, (B) reduce the interest
rate applicable to the Obligations hereunder in which such Participant is
participating, (C) release all or a material portion of the Collateral or
guaranties (except to the extent expressly provided herein or in any of the Loan
Documents) supporting the Obligations hereunder in which such Participant is
participating, (D) postpone the payment of, or reduce the amount of, the
interest or fees payable to such Participant through Foothill, or (E) change the
amount or due dates of scheduled principal repayments or prepayments or
premiums, and (v) all amounts payable by Borrowers hereunder shall be determined
as if Foothill had not sold such participation, except that, if amounts
outstanding under this Agreement are due and unpaid, or shall have been declared
or shall have become due and payable upon the occurrence of an Event of Default,
each Participant shall be deemed to have the right of set-off in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Foothill under this Agreement. The rights of any Participant only shall be
derivative through Foothill and no Participant shall have any rights under this
Agreement or the other Loan Documents or any direct rights as to Borrowers, the
Collections, the Collateral, or otherwise in respect of the Obligations. No
Participant shall have the right to participate directly in the making of
decisions by Foothill.

                                       56
<PAGE>

              (e)  In connection with any such assignment or participation or
proposed assignment or participation, a Foothill may disclose all documents and
information which it now or hereafter may have relating to Borrowers or
Borrowers' business.

              (f)  Any other provision in this Agreement notwithstanding,
Foothill may at any time create a security interest in, or pledge, all or any
portion of its rights under and interest in this Agreement in favor of any
Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Bank
or U.S. Treasury Regulation 31 CFR (S)203.14, and such Federal Reserve Bank may
enforce such pledge or security interest in any manner permitted under
applicable law.

        14.2  Successors.  This Agreement shall bind and inure to the benefit
of the respective successors and assigns of each of the parties; provided,
                                                                 --------
however, that Borrowers may not assign this Agreement or any rights or duties
-------
hereunder without Foothill's prior written consent and any prohibited assignment
shall be absolutely void ab initio. No consent to assignment by Foothill shall
release any Borrower from its Obligations. Foothill may assign this Agreement
and the other Loan Documents and its rights and duties hereunder and thereunder
pursuant to Section 14.1 hereof and, except as expressly required pursuant to
            ------------
Section 14.1 hereof, no consent or approval by any Borrower is required in
------------
connection with any such assignment.

    15. AMENDMENTS; WAIVERS.

        15.1  Amendments and Waivers.  No amendment or waiver of any provision
of this Agreement or any other Loan Document, and no consent with respect to any
departure by Borrowers therefrom, shall be effective unless the same shall be in
writing and signed by Foothill and Administrative Borrower (on behalf of all
Borrowers) and then any such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given

        15.2  No Waivers; Cumulative Remedies.  No failure by Foothill to
exercise any right, remedy, or option under this Agreement or, any other Loan
Document, or delay by Foothill in exercising the same, will operate as a waiver
thereof. No waiver by Foothill will be effective unless it is in writing, and
then only to the extent specifically stated. No waiver by Foothill on any
occasion shall affect or diminish Foothill's rights thereafter to require strict
performance by Borrowers of any provision of this Agreement. Foothill's rights
under this Agreement and the other Loan Documents will be cumulative and not
exclusive of any other right or remedy that Foothill may have.

    16. GENERAL PROVISIONS.

        16.1  Effectiveness.  This Agreement shall be binding and deemed
effective when executed by Borrowers and Foothill.

        16.2  Destruction of Borrowers' Documents. All documents, schedules,
invoices, agings, or other papers delivered to Foothill may be destroyed or
otherwise disposed of by Foothill four months after they are delivered to or
received by Foothill, unless Administrative Borrower requests, in writing, the
return of said documents, schedules, or other papers and makes arrangements, at
Borrowers' expense, for their return.

        16.3  Section Headings.  Headings and numbers have been set forth
herein for convenience only. Unless the contrary is compelled by the context,
everything contained in each section applies equally to this entire Agreement.

        16.4  Interpretation.  Neither this Agreement nor any uncertainty or
ambiguity herein shall be construed or resolved against Foothill or Borrowers,
whether under any rule of construction or otherwise. On the contrary, this
Agreement has been reviewed by all parties and shall be construed and
interpreted according to the ordinary meaning of the words used so as to fairly
accomplish the purposes and intentions of all parties hereto.

        16.5  Severability of Provisions.  Each provision of this Agreement
shall be severable from every other provision of this Agreement for the purpose
of determining the legal enforceability of any specific provision.

        16.6  Withholding Taxes.  All payments made by Borrowers hereunder or
under any note will be made without setoff, counterclaim, or other defense,
except as required by applicable law other than for Taxes (as defined below).
All such payments will be made free and clear of, and without deduction or
withholding for, any present or future taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed by any
jurisdiction (other than the United States) or by any political subdivision or
taxing authority thereof or therein (other than of the United States) with
respect to such payments (but excluding, any tax imposed by any jurisdiction or
by any political subdivision or taxing authority thereof or therein (i) measured
by or based on the net income or net profits of Foothill, or (ii) to the extent
that such tax results from a change in the circumstances of Foothill, including
a change in the residence, place of organization, or principal place of business
of Foothill, or a change in the branch or lending office of Foothill
participating in the transactions set forth herein) and all interest, penalties
or similar liabilities with respect thereto (all such non-excluded taxes,
levies, imposts, duties, fees, assessments or other charges being referred to
collectively as "Taxes"). If any Taxes are so levied or imposed, each Borrower
                 -----
agrees to pay the full amount of such Taxes, and such additional amounts as may
be necessary so that every payment of all amounts due under this Agreement or
under any note, including any amount paid pursuant to this Section 16.6 after
                                                           ------------
withholding or deduction for or on account of any Taxes, will not be less than
the amount provided for herein; provided, however, that Borrowers shall not be
                                --------  -------
required to increase any such amounts payable to Foothill if the increase in
such amount payable results from Foothill's own willful misconduct or gross
negligence. Borrowers will furnish to Foothill as promptly as possible after the
date the payment of any Taxes is due pursuant to applicable law certified copies
of tax receipts evidencing such payment by Borrowers.

        16.7  Counterparts; Telefacsimile Execution.  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 an original executed
counterpart of this Agreement. Any party delivering an executed counterpart of
this Agreement by telefacsimile also shall deliver an original executed
counterpart of this Agreement but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Agreement.

                                       58
<PAGE>

        16.8  Revival and Reinstatement of Obligations.  If the incurrence or
payment of the Obligations by any Borrower or any guarantor of the Obligations
or the transfer by either or both of such parties to Foothill of any property of
either or both of such parties should for any reason subsequently be declared to
be void or voidable under any state or federal law relating to creditors'
rights, including provisions of the Bankruptcy Code relating to fraudulent
conveyances, preferences, and other voidable or recoverable payments of money or
transfers of property (collectively, a "Voidable Transfer"), and if Foothill is
required to repay or restore, in whole or in part, any such Voidable Transfer,
or elects to do so upon the reasonable advice of its counsel, then, as to any
such Voidable Transfer, or the amount thereof that Foothill is required or
elects to repay or restore, and as to all reasonable costs, expenses, and
attorneys fees of Foothill related thereto, the liability of Borrowers or such
guarantor automatically shall be revived, reinstated, and restored and shall
exist as though such Voidable Transfer had never been made.

        16.9  Integration.  This Agreement, together with the other Loan
Documents, reflects the entire understanding of the parties with respect to the
transactions contemplated hereby and shall not be contradicted or qualified by
any other agreement, oral or written, before the date hereof.

        16.10 P-Com as Agent for Borrowers. Each Borrower hereby irrevocably
appoints P-Com as the borrowing agent and attorney-in-fact for all Borrowers
(the "Administrative Borrower") which appointment shall remain in full force and
      -----------------------
effect unless and until Foothill shall have received prior written notice signed
by each Borrower that such appointment has been revoked and that another
Borrower has been appointed Administrative Borrower. Each Borrower hereby
irrevocably appoints and authorizes the Administrative Borrower (i) to provide
Foothill with all notices with respect to Advances obtained for the benefit of
any Borrower and all other notices and instructions under this Agreement and
(ii) to take such action as the Administrative Borrower deems appropriate on its
behalf to obtain Advances and to exercise such other powers as are reasonably
incidental thereto to carry out the purposes of this Agreement. It is understood
that the handling of the Loan Account and Collateral of Borrowers in a combined
fashion, as more fully set forth herein, is done solely as an accommodation to
Borrowers in order to utilize the collective borrowing powers of Borrowers in
the most efficient and economical manner and at their request, and that Foothill
shall not incur liability to any Borrower as a result hereof. Each Borrower
expects to derive benefit, directly or indirectly, from the handling of the Loan
Account and the Collateral in a combined fashion since the successful operation
of each Borrower is dependent on the continued successful performance of the
integrated group. To induce Foothill to do so, and in consideration thereof,
each Borrower hereby jointly and severally agrees to indemnify Foothill and hold
Foothill harmless against any and all liability, expense, loss or claim of
damage or injury, made against Foothill by any Borrower or by any third party
whosoever, arising from or incurred by reason of (a) the handling of the Loan
Account and Collateral of Borrowers as herein provided, (b) Foothill's relying
on any instructions of the Administrative Borrower, or (c) any other action
taken by Foothill hereunder or under the other Loan Documents, except that
Borrowers will have no liability to

                                       59
<PAGE>

Foothill under this Section 16.10 with respect to any liability that has been
                    -------------
finally determined by a court of competent jurisdiction to have resulted solely
from the gross negligence or willful misconduct of Foothill.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed in Los Angeles, California.
