reference to LIBOR or the Floating Rate for such Interest Period.  All Borrowing
Requests and confirmations thereof in writing or by facsimile must be signed by
an officer of Borrower who has been identified in writing to Agent as an officer
authorized to make Borrowing Requests on behalf of Borrower. Notwithstanding the
foregoing, in the case of the Purpose Line, Borrowing Requests shall be
accompanied by sufficient documentation for Agent and the Lenders to evaluate
the assets or business the Borrower proposes to acquire with the proceeds of the
requested loan, including any applicable purchase orders, equipment
specifications and acquisition agreements, and such Borrowing Requests and
documentation shall be delivered sufficiently in advance of the proposed date of
disbursement to permit Agent and the Lenders to evaluate the acquisition to be
financed by the requested loan.

     2.5  Lenders' Records.  With respect to each Loan, each Lender is hereby

     Borrower shall, concurrently with the reduction of the Revolving Commitment
     Limit, make a prepayment of the Revolving Loan in an amount sufficient to
     cause Borrower to be in compliance with the Available Amount after giving
     effect to such reduction; and

based at the rate per annum equal to the sum of the Base Rate from time to time
plus the Applicable Base Rate Margin (the "Floating Rate") or, at Borrower's
                                           -------------                    
election subject to the following provisions of this Section 3.1, at the rate
                                                     -----------             
per annum equal to the sum of LIBOR plus the Applicable LIBOR Margin (the "LIBOR
                                                                           -----
Rate"); provided, that following the occurrence of an Event of Default, all
----    --------                                                           
amounts outstanding under each Facility shall, at the option of Agent, bear
interest at the rate per annum equal to the sum of the Floating Rate then
applicable to such Facility plus 3%.  A portion of principal outstanding
hereunder bearing interest at the Floating Rate shall be referred to as a
"Floating Rate Loan"; and a portion of principal outstanding hereunder bearing
 ------------------
interest at the LIBOR Rate shall be referred to as a "LIBOR Loan".  With respect
                                                      ----------

(or, subject to Section 3.7, on any other Business Day), convert such loan to a

Floating Rate Loan.  Borrower may at any time convert a Floating Rate Loan into
a LIBOR Loan.  At the time any advance is requested under a Facility, and/or
Borrower wishes to have the LIBOR Rate apply to all or a portion of the
outstanding principal of the Loans, and at the end of each Interest Period,
Borrower shall give Agent notice specifying (i) the interest rate option
selected by  Borrower, (ii) the principal amount to be subject to such interest
rate, and (iii) if the LIBOR Rate is selected, the length of the applicable
Interest Period.  Any such notice may be given by telephone so long as, in the
case of LIBOR Loans, (x) Agent received written confirmation of such telephonic
notice not later than three (3) Business Days after such telephonic notice is
given, and (y) such notice is given to Agent prior to 10:00 a.m., California
time, on the first day of the requested Interest Period.  Notwithstanding the
foregoing, Borrower may only request the LIBOR Rate with respect to the
Revolving Loan, and only for amounts of principal that are at least $500,000 in
the aggregate and integral multiples of $100,000.  If, upon any request to have
the LIBOR Rate apply to any portion of the Loans, Borrower does not immediately
accept the LIBOR Rate quoted by Agent, any subsequent acceptance by Borrower
shall be subject to a redetermination of the LIBOR Rate by Agent; provided that
                                                                  --------     
if Borrower fails to accept any such quotation as given, then the quoted rate
shall expire and Agent shall be under no obligation to permit Borrower to select
the LIBOR Rate on such day.   With respect to any portion of the Loans for which
the LIBOR Rate has not been duly selected in accordance with the foregoing
provisions of this Section 3.1, Borrower will be deemed to have selected the
                   -----------                                              
Floating Rate.  Each portion of the Loans bearing interest at the LIBOR Rate
must remain outstanding for the Interest Period selected for such portion of the
Loans by Borrower.

     3.2  Interest Payments and Computations.  Accrued interest on all
          ----------------------------------                          
outstanding Loans shall be due and payable on the last Business Day of each
month.  Interest on LIBOR Loans shall be computed on the basis of a 360-day year
and shall be assessed for the actual number of days elapsed from the first day
of the applicable Interest Period, but excluding the last day of such period.
Interest on each Floating Rate Loan shall be computed on the basis of a 360-day
year and shall be assessed for the actual number of days elapsed.

     3.3  Principal Payments.  The outstanding principal of the Loans shall be

of disbursement thereof in substantially equal monthly installments plus
interest; provided, that the loan of up to $1,000,000 disbursed on the Closing

connection therewith.  All Net Cash Proceeds received by Borrower and its
Subsidiaries in excess of $250,000 in the aggregate in any fiscal year (or, in
the case of Net Cash Proceeds derived from the issuance or sale by Borrower of
any of its equity interests or any issuance of indebtedness which is subordinate
to the Obligations on terms and conditions satisfactory to Agent, 50% of such
excess Net Cash Proceeds) shall be paid, immediately upon receipt thereof, to
Agent (for the benefit of the Lenders as hereinafter provided) in immediately
available funds, together with unpaid interest accrued on such amount to the
date of such payment but without prepayment charge or premium, unless prior to
                                                               ------

Proceeds, Agent (at the direction of  Lenders holding at least 66 2/3% of the

foregoing, in the case of any Net Cash Proceeds consisting of insurance proceeds
or condemnation awards, Borrower and its Subsidiaries shall have the option
(exercisable by written notice to Agent delivered concurrently with the notice
required by the first sentence of this subsection (d) (A) to replace the

(which for these purposes will include all scheduled installments of long term
debt that would otherwise be treated as "current portions" under GAAP as of the
date of determination, regardless of whether any such installments have been
prepaid) and Capital Expenditures incurred but not financed during the
applicable period, all calculated excluding any accounting items in respect of
Net Cash Proceeds received during the most recently ended fiscal year that were
applied in accordance with Section 3.3(d).  Such prepayment shall be applied

against the remaining installments of the Term Loan on a pro-rata basis based
upon the number and amounts of such installments.

          (f)  Anything herein to the contrary notwithstanding, the aggregate
outstanding principal amount of the Revolving Loan shall not at any time exceed
the Available Amount as from time to time determined (in accordance with the
most recently delivered Borrowing Base Certificate), and no Advance may be
requested unless after giving effect thereto  Borrower is in compliance with
foregoing requirement.  In the event that the aggregate outstanding principal
amount of the Revolving Loan shall at any time and for any reason (including,
without limitation, a decrease in the amount of the Borrowing Base) exceed the
Available Amount then in effect, Borrower shall, without notice or demand, pay
not later than the Business Day after the date such excess is determined the
amount of such excess to Agent as a prepayment of the principal amount of the
Revolving Loan, together with all unpaid interest accrued on the amount of such
excess to such date but without prepayment charge or premium.  Upon any
determination by Borrower that a prepayment of the Revolving Loan is required
pursuant to this Section 3.3(f), Borrower shall immediately notify Agent in

writing of such determination, specifying the amounts of principal and interest
required to be prepaid hereunder and the date on which such prepayment will
occur.

determination shall, upon notice thereof to Borrower and Agent, be conclusive
and binding on Borrower) that the introduction of or any change in or in the
interpretation of any law makes it unlawful, or any central bank or other
Governmental Body asserts that it is unlawful, for such Lender to make, continue
or maintain any loan as, or to convert any loan into, a LIBOR Loan,  the
obligations of such Lender to make, continue, maintain or convert any such loans
shall, upon such determination, forthwith be suspended until Lender shall notify
Borrower and Agent that the circumstances causing such suspension no longer
exist, and all LIBOR Loans shall automatically convert into Floating Rate Loans
at the end of the then current Interest Periods with respect thereto or sooner,
if required by such law or assertion.

     3.5  Deposits Unavailable.  If any Lender shall have determined that by
          --------------------                                              
reason of circumstances affecting such Lender's relevant market, adequate means
do not exist for ascertaining the interest rate applicable hereunder to LIBOR
Loans, then, upon notice from such Lender to Borrower, the obligations of such
Lender to make or continue any loans as, or to convert 

                                       20

any loans into, LIBOR Loans shall forthwith be suspended until such Lender shall
notify Borrower and Agent that the circumstances causing such suspension no
longer exist.

     3.6  Increased LIBOR Loan Costs, etc.  Borrower agrees to reimburse each
          -------------------------------                                    
Lender for any increase in the cost to such Lender (by reason of the
introduction of or any change in or in the interpretation of any law) of, or any
reduction in the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any loans as, or of converting (or of its obligation to convert) any
loans into, LIBOR Loans.  Each Lender shall promptly notify Borrower and Agent
in writing of the occurrence of any such event, such notice to state, in
reasonable detail, the reasons therefor and the additional amount required fully
to compensate such Lender for such increased cost or reduced amount.  Such
additional amounts shall be payable by Borrower directly to such Lender within
five days of its receipt of such notice, and such notice shall, in the absence
of manifest error, be conclusive and binding on Borrower.

     3.7  Funding Losses.  In the event that  any Lender shall incur any loss or
          --------------                                                        
expense (including any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to make,
continue or maintain any portion of the principal amount of any loan as, or to
convert any portion of the principal amount of any loan into, a LIBOR Loan) as a
result of (a) any conversion or repayment or prepayment of the principal amount
of any LIBOR Loan on a date other than the scheduled last day of the Interest
Period applicable thereto, for any reason, or (b) any loans not being made as
LIBOR Loans in accordance with Borrower's request therefor; then, upon the
written notice of such Lender to Borrower and Agent, Borrower shall, within five
days of its receipt thereof, pay directly to such Lender such amount as will (in
such Lender's reasonable determination) reimburse such Lender for such loss or
expense.  Such written notice (which shall include calculations in reasonable
detail) shall, in the absence of manifest error, be conclusive and binding on
Borrower.

     ------------------------ 

     4.1  Security Interest.  As collateral security for the prompt and complete
          -----------------

otherwise) of all the Obligations, Borrower and each of its Subsidiaries shall

Agent may, by notice to Borrower, declare all or any portion of the outstanding
principal amount of the Obligations to be due and payable and/or the Loans and
the Commitment (if not theretofore terminated) to be terminated, whereupon the

     8.3  Remedies with Respect to Collateral.
          ----------------------------------- 

          (a)  Without limiting the foregoing, if any Event of Default shall
occur and be continuing,  Agent may exercise, in addition to all other rights
and remedies granted to it in this Agreement, any other Loan Document or by law,
all rights and remedies of a secured party under the UCC.  Without limiting the
generality of the foregoing, Borrower expressly agrees that in any such event
Agent may, without demand of performance or other demand, advertisement, legal
process or notice of any kind (except as may be required by law or provided
herein) to or upon 

                                       49
<PAGE>
 
Borrower or any other Person (all and each of which demands, advertisements
and/or notices are hereby expressly waived to the maximum extent permitted by
the UCC and other applicable law), (i) at any time or times enter Borrower's
premises and take physical possession of the Collateral and maintain such
possession on Borrower's premises, without any obligation to pay rent or other
compensation to Borrower, (ii) remove the Collateral or any part thereof, to
such other places as Agent may desire, (iii) forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or (iv)
forthwith sell, lease, assign, give an option or options to purchase, or sell or
otherwise dispose of and deliver said Collateral (or contract to do so), or any
part thereof, in one or more parcels at public or private sale or sales, at any
exchange or broker's board or at any of Agent's offices or elsewhere at such
prices and on such terms as Agent may deem commercially reasonable (irrespective
of the impact of any such sales on the market price of the Collateral), for cash
or on credit or for future delivery. Any such purchaser (including, without
limitation, Agent and any other Lender) of Collateral sold pursuant to this
Section 8.3 shall purchase the same absolutely free from any claim or right on
-----------
the part of Borrower and Borrower does hereby waive (to the maximum extent
permitted by the UCC and other applicable law) all rights of redemption, stay,
and appraisal which Borrower now has or may at any time in the future have under
any rule of law or statute now existing or hereafter enacted. Borrower further
agrees, at Agent's request to assemble the Collateral and make it available to
Agent at places which Agent shall reasonably select, whether at Borrower's
premises or elsewhere. To the maximum extent permitted by applicable law,
Borrower waives all claims, damages, and demands against Agent arising out of
the repossession, retention or sale of the Collateral except such as may arise
out of the gross negligence or willful misconduct of Agent or the failure of
Agent to exercise reasonable care in the custody and preservation of Collateral
in its possession or under its control as provided in Section 4.3. Borrower
                                                      -----------
agrees that, to the extent notice of sale shall be required by law, Agent need
not give more than ten (10) days' notice of the time and place of any public
sale or of the time after which a private sale may take place and that such
notice shall constitute reasonable notification within the meaning of Section
9504(3) of the UCC.

          (b)  Borrower also agrees to pay all reasonable costs of Agent and
Lenders, including, without limitation, reasonable attorneys' fees, incurred in
connection with the enforcement of any of its rights and remedies hereunder,
including, without limitation, reasonable fees for attorneys employed by  Agent
or any Lenders to collect any deficiency existing after the application of
proceeds from any sale of Collateral pursuant to this Section 8.3.
                                                      ----------- 

          (c)  Borrower hereby waives presentment, demand, protest or any notice
(to the maximum extent permitted by applicable law) of any kind in connection
with this Agreement or any Collateral.

          (d)  The proceeds of any disposition of any Collateral obtained
pursuant to this Section 8.3 and\or the other Loan Documents shall be applied as
                 -----------                                                    
follows:

               (i)  first, to the payment of any and all expenses and fees
     (including reasonable attorney's fees) incurred by  Agent in foreclosing on
     and disposing of the Collateral;

               (ii) next, any surplus then remaining to the payment of the
     Obligations (whether matured or unmatured) in such order as Agent may
     determine in its sole discretion; and

                                       50
<PAGE>
 
               (iii) thereafter, if no other Obligations are outstanding, any
     surplus then remaining shall be paid to Borrower or to such other Person
     legally entitled to same; it being understood that Borrower will remain
     liable to Agent and the Lenders to the extent of any deficiency between the
     amount of the Obligations and the aggregate of all amount realized from
     Collateral.


9.   THE AGENT
     ---------

     9.1  Actions.  Each Lender hereby appoints COMERICA BANK-CALIFORNIA
          -------                                                       
("Comerica") as its Agent under and for purposes of this Agreement and each
 ----------                                                                 
other Loan Document.  Each Lender authorizes Agent to act on behalf of such
Lender under this Agreement and each other Loan Document and, in the absence of
other written instructions from the Required Lenders received from time to time
by Agent (with respect to which Agent agrees that it will comply, except as
otherwise provided in this Section or as otherwise advised by counsel), to
exercise such powers hereunder and thereunder as are specifically delegated to
or required of  Agent by the terms hereof and thereof, together with such powers
as may be reasonably incidental thereto. Each Lender hereby indemnifies (which
indemnity shall survive any termination of this Agreement) Agent, pro rata
                                                                  --- ----
according to such Lender's Percentage, from and against any and all liabilities,
obligations, losses, damages, claims, costs or expenses of any kind or nature
whatsoever which may at any time be imposed on, incurred by, or asserted
against, Agent in any way relating to or arising out of this Agreement and any
other Loan Document, including reasonable attorneys' fees, and as to which Agent
is not reimbursed by Borrower; provided, however, that no Lender shall be liable
                               --------  -------                                
for the payment of any portion of such liabilities, obligations, losses,
damages, claims, costs or expenses which are determined by a court of competent
jurisdiction in a final proceeding to have resulted solely from Agent's gross
negligence or wilful misconduct.  Agent shall not be required to take any action
hereunder, or under any other Loan Document, or to prosecute or defend any suit
in respect of this Agreement  or any other Loan Document, unless it is
indemnified hereunder to its satisfaction.  If any indemnity in favor of Agent
shall be or become, in Agent's determination, inadequate, Agent may call for
additional indemnification from the Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given.

     9.2  Funding Reliance, etc.  Unless Agent shall have been notified by
          ---------------------                                           
telephone, confirmed in writing, by any Lender by 5:00 p.m., Pacific time, on
the day prior to an Advance or Purpose Line disbursement that such Lender will
not make available the amount which would constitute its Percentage of such
Advance or disbursement on the date specified therefor, Agent may assume that
such Lender has made such amount available to Agent and, in reliance upon such
assumption, make available to Borrower a corresponding amount.  If and to the
extent that such Lender shall not have made such amount available to Agent, such
Lender and Borrower severally agree to repay Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
Agent made such amount available to Borrower to the date such amount is repaid
to Agent, at the interest rate applicable at the time to the portion of the
Revolving Loan comprising such Advance or to such Purpose Line disbursement, as
the case may be.

     9.3  Exculpation.  Neither Agent nor any of its directors, officers,
          -----------                                                    
employees or agents shall be liable to any Lender for any action taken or
omitted to be taken by it under this Agreement or any other Loan Document, or in
connection herewith or therewith, except for its own wilful misconduct or gross
negligence, nor responsible for any recitals or warranties herein or therein,

                                       51
<PAGE>
 
nor for the effectiveness, enforceability, validity or due execution of this
Agreement or any other Loan Document, nor for the creation, perfection or
priority of any Liens purported to be created by any of the Loan Documents, or
the validity, genuineness, enforceability, existence, value or sufficiency of
any collateral security, nor to make any inquiry respecting the performance by
Borrower or any of its Subsidiaries of their respective obligations under the
Loan Documents.  Any such inquiry which may be made by Agent shall not obligate
it to make any further inquiry or to take any action.  Agent shall be entitled
to rely upon advice of counsel concerning legal matters and upon any notice,
consent, certificate, statement or writing which  Agent believes to be genuine
and to have been presented by a proper Person.

     9.4  Successor.  Agent may resign as such at any time upon at least 30
          ---------                                                        
days' prior notice to Borrower and all Lenders.  If Agent at any time shall
resign, the Required Lenders may appoint another Lender as a successor Agent
which shall thereupon become Agent hereunder.  If no successor Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Agent's giving notice of
resignation, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be one of the Lenders or a commercial banking
institution organized under the laws of the U.S. (or any State thereof) or a
U.S. branch or agency of a commercial banking institution, and having a combined
capital and surplus of at least $50,000,000.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
be entitled to receive from the retiring Agent such documents of transfer and
assignment as such successor Agent may reasonably request, and shall thereupon
succeed to and become vested with all rights, powers, privileges and duties of
the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations under this Agreement.  After any retiring Agent's resignation
hereunder as Agent, the provisions of this Section 9 shall inure to its benefit
                                           ---------                           
as to any actions taken or omitted to be taken by it while it was Agent under
this Agreement; and Sections 10.8 and 10.9 shall continue to inure to its
                    -------------     ----                               
benefit.

     9.5  Loans and other Transactions by Comerica.  Comerica shall have the
          ----------------------------------------                          
same rights and powers with respect to (x) the Revolving Loan made by it or any
of its Affiliates, and (y) the Notes held by it or any of its Affiliates as any
other Lender and may exercise the same as if it were not Agent.  Comerica and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of business with Borrower, any of its Subsidiaries or any of their
Affiliates as if Comerica were not Agent hereunder.

     9.6  Credit Decisions. Each Lender acknowledges that it has, independently
          ----------------
of Agent and each other Lender, and based on such Lender's review of the
financial information of Borrower and its Subsidiaries, this Agreement, the
other Loan Documents (the terms and provisions of which being satisfactory to
such Lender) and such other documents, information and investigations as such
Lender has deemed appropriate, made its own credit decision to extend its
Commitment. Each Lender also acknowledges that it will, independently of Agent
and each other Lender, and based on such other documents, information and
investigations as it shall deem appropriate at any time, continue to make its
own credit decisions as to exercising or not exercising from time to time any
rights and privileges available to it under this Agreement or any other Loan
Document.

     9.7  Copies, etc.  Agent shall give prompt notice to each Lender of each
          -----------                                                        
notice or request required or permitted to be given to Agent by Borrower
pursuant to the terms of this Agreement (unless concurrently delivered to the

delegation shall be of a constant, and not a varying, percentage of all the
assigning Lender's Commitment and shall be allocated ratably among the Revolving
Loan, the Term Loan and the Purpose Line); provided, however, that Borrower and
                                           --------  -------                   
Agent shall be entitled to continue to deal solely and directly with such Lender
in connection with the interests so assigned and delegated to an Assignee Lender
until (i) written notice of such assignment and delegation, together with
payment instructions, addresses and related information with respect to such
Assignee Lender, shall have been given to Borrower and Agent by such Lender and
such Assignee Lender; and (ii) Agent shall have received its customary
processing fee from such Lender or Assignee Lender and an executed assignment
agreement in form and substance satisfactory to Agent.  Notwithstanding the
foregoing, not less than 50% of the aggregate Commitments shall at all times be
held by Comerica Bank-California and/or one of more of its Affiliates.

          From and after the date that an assignment becomes effective as
provided in the preceding paragraph, (x) the Assignee Lender thereunder shall be
deemed automatically to have become a party hereto and to the extent that rights
and obligations hereunder have been assigned and delegated to such Assignee
Lender in connection with such assignment, shall have the rights and obligations
of a Lender hereunder and under the other Loan Documents, and (y) the assignor
Lender, to the extent that rights and obligations hereunder have been assigned
and delegated by it in connection with such assignment, shall be released from
its obligations hereunder and under the other Loan Documents.  Within 5 Business
Days after its receipt of notice of such assignment, Borrower shall execute and
deliver to Agent (for delivery to the relevant Assignee Lender) new Notes
evidencing such Assignee Lender's assigned Commitment and, if the assignor
Lender has retained a Commitment hereunder, replacement Notes each in the
principal amount of the applicable Loan retained by the assignor Lender
hereunder (each such Note to be in exchange for, but not in payment of, the Note
then held by such assignor Lender).  Each such replacement Note shall be dated
the date of the predecessor Note.  The assignor Lender shall mark the
predecessor Note "exchanged" and deliver it to Borrower.  Accrued interest on
that part of the predecessor Note evidenced by the replacement Note, and accrued
fees, shall be paid as provided in the documentation effecting the Assignment.
Accrued interest on that part of the predecessor Note evidenced by the Revolving
Note shall be paid to the assignor Lender.  Accrued interest and accrued fees
shall be paid at the same time or times provided in the predecessor Note and in
this Agreement.  Any attempted assignment and delegation not made in accordance
with this Section 10.2(a) shall be null and void.

     Document, except that such Lender may agree with any Participant that such
     Lender will not, without such Participant's consent, take any actions of
     the type described in clause (b) or (c) of Section 10.6.

     10.7 Set Offs.  Upon the occurrence and during the continuance of any Event
          --------                                                              
of Default, Agent and each Lender is hereby authorized at any time and from time
to time, without notice to Borrower (any such notice being expressly waived by
Borrower), to set off and apply to the payment of the Obligations (whether or

therefor), and (as security for such Obligations) Borrower hereby grants to
Agent (for the benefit of the Lenders) a continuing security interest in, any

from and against any and all actions, causes of action, suits, losses, costs,
liabilities and damages, and expenses incurred in connection therewith
(irrespective of whether any such Indemnified Party is a party to the action for
which indemnification hereunder is sought), including reasonable attorneys' fees
and disbursements (collectively, the "Indemnified Liabilities"), incurred by the
                                      -----------------------                   
Indemnified Parties or any of them as a result of, or arising out of, or
relating to any transaction financed or to be financed in whole or in part,

misconduct.  If and to the extent that the foregoing undertaking may be
unenforceable for any 

                                       56

reason, Borrower hereby agrees to make the maximum contribution to the payment

provide information regarding Borrower and the Loans to their respective
parents, subsidiaries, affiliates and service providers in each case in
accordance with their respective customary business practices.

      10.11 Counterparts.  This Agreement may be executed in any number of
            ------------

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.

      10.12 Integration. This Agreement, together with the other Loan Documents,

any act, delay, omission or otherwise be deemed to have waived any of its rights
or remedies hereunder, and no waiver shall be valid unless in writing, signed by
Agent and the Lenders and then only to the extent expressly provided therein.  A
waiver by  Agent and the Lenders of any right or remedy hereunder on any one

the Lenders would otherwise have had on any future occasion.  No failure to
exercise nor any delay in exercising on the part of  Agent and the Lenders, any
right, power or privilege hereunder, shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude any other or future exercise thereof or the exercise of any other
right, power or privilege.  The rights and remedies hereunder provided are
cumulative and may be exercised singly or concurrently, and are not exclusive of
any rights and remedies provided by law.

      10.14 GOVERNING LAW. THIS AGREEMENT, THE NOTES AND ALL OTHER LOAN

            --------------------                                               
THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED.
EACH OF THE PARTIES HERETO HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVES (AFTER CONSULTING OR HAVING THE OPPORTUNITY TO CONSULT WITH COUNSEL OF
THEIR CHOICE) ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY HERETO.
EACH OF THE PARTIES ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND
