                                                                   EXHIBIT 10.13

                           (a) Subject to and upon the terms and conditions of
this Agreement, Bank shall make a Term Loan available to Borrower.

                           (b) When Borrower desires to obtain the Credit
Extension, Borrower will notify Bank by facsimile transmission or telephone no
later than 3:00 p.m. Pacific time, on the Business Day that the Credit
Extension is to be made. The notification shall be promptly confirmed by a
Payment/Advance Form in substantially the form of EXHIBIT B hereto. Bank is
authorized to make the Credit Extension under this Agreement, based upon
instructions received from a Responsible Officer or a designee of a
Responsible Officer. Bank shall be entitled to rely on any telephonic notice
given by a person who Bank reasonably believes to be a Responsible Officer or
a designee thereof, and Borrower shall indemnify and hold Bank harmless for
any damages or loss suffered by Bank as a result of such reliance. Bank will
credit the amount of the Credit Extension made under this SECTION 2.1 to
Borrower's deposit account.

                           (c) The Term Loan shall terminate on the Term
Maturity Date, at which time all Obligations under this SECTION 2.1 and other
amounts due under this Agreement (except as otherwise expressly specified
herein) shall be immediately due and payable.

         2.2      INTEREST RATES, PAYMENTS, AND CALCULATIONS.

                           (a) INTEREST RATE. Except as set forth in SECTION
2.2(B), Credit Extensions shall bear interest, on the average daily balance
thereof, at a per annum rate equal to twelve percent (12%).

                           (b) DEFAULT RATE. All Obligations shall bear
interest, from and after the occurrence of an Event of Default, at the
"Default Interest Rate." The Default Interest Rate shall be, at Bank's option,
(i) the Maximum Lawful Rate, if such Maximum Lawful Rate is established by
applicable law: or (ii) the interest rate applicable immediately prior to the
occurrence of the Event of Default plus five (5) percentage points, if no
Maximum Lawful Rate is established by applicable law: or (iii) eighteen
percent (18%) per annum: or (iv) such lesser rate of interest as Bank's, its
sole discretion may choose to charge: but never more than the Maximum Lawful
Rate or at a rate that would cause the total interest contracted for, charged
or received by Bank to exceed the Maximum Lawful Amount.

                           (c) PAYMENTS. Interest hereunder shall be due and
payable on each Payment Date. Any interest not paid when due shall be
compounded by becoming a part of the Obligations, and such interest shall
thereafter accrue interest at the rate then applicable hereunder.

                           (d) COMPUTATION.

                               (i) SPREADING OF INTEREST. Because of the
possibility of irregular periodic balances of principal, the fluctuating
nature of the interest rate, or premature payment, the total interest that
will accrue under this Agreement cannot be determined in advance. Bank does
not intend to contract for charge or receive more than the Maximum Lawful Rate
or Maximum Lawful Amount permitted by applicable state or federal law, and to
prevent such an occurrence Bank and Borrower agree that all amounts of
interest, whenever contracted for, charged or received by Bank, with respect
to the loan of money evidenced by the Loan

                                       7

<PAGE>

                                                                   EXHIBIT 10.13

Documents, shall be spread, prorated or allocated over the full period of time
the Obligations are unpaid, including the period of any renewal or extension
thereof. If the maturity of the Obligations is accelerated for any reason
whether as a lawsuit or an Event of Default or otherwise prior to the full
stated term, the total amount of interest contracted for, charged or received
to the time of such demand shall be spread, prorated or allocated along with
any interest thereafter accruing over the full period of time that the
Obligations thereafter remain unpaid for the purpose of determining if such
interest exceeds the Maximum Lawful Amount.

                               (ii) EXCESS INTEREST. At maturity (whether by
acceleration or otherwise) or on earlier final payment of the Obligations,
Bank shall compute the total amount of interest that has been contracted for,
charged or received by Bank or payable by Borrower hereunder and compare such
amount to the Maximum Lawful Amount that could have been contracted for,
charged or received by Bank. If such computation reflects that the total
amount of interest that has been contracted for, charged or received by Bank
or payable by Borrower exceeds the Maximum Lawful Amount, then Bank shall
apply such excess to the reduction of the principal balance and not to the
payment of interest: or if such excess interest exceeds the unpaid principal
balance, such excess shall be refunded to Borrower. This provision concerning
the crediting or refund of excess interest shall control and take precedence
over all other agreements between Borrower and Bank so that under no
circumstances shall the total interest contracted for, charged or received by
Bank exceed the Maximum Lawful Amount.

                               (iii) DAILY COMPUTATION OF INTEREST. To the
extent permitted by applicable law, Bank at its option may either (i)
calculate the per diem interest rate or amount based on the actual number of
days in the year (365 or 366, as the case may be), and charge that per diem
interest rate or amount each day, or (ii) calculate the per diem interest rate
or amount as if each year has only 360 days, and charge that per diem interest
rate or amount each day for the actual number of days of the year (365 or 366
as the case may be). If the Loan Documents call for monthly payments, Bank at
its option may determine the payment amount based on the assumption that each
year has only 360 days and each month has 30 days. In no event shall Bank
compute the interest in a manner that would cause Bank to contract for, charge
or receive interest that would exceed the Maximum Lawful Rate or the Maximum
Lawful Amount.

         2.3 CREDITING PAYMENTS. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment, whether directed to Borrower's deposit
account with Bank or to the Obligations or otherwise, shall be immediately
applied to conditionally reduce Obligations, but shall not be considered a
payment in respect of the Obligations unless such payment is of immediately
available federal funds or unless and until such check or other item of
payment is honored when presented for payment. Notwithstanding anything to the
contrary contained herein, any wire transfer or payment received by Bank after
12:00 noon Pacific time shall be deemed to have been received by Bank as of
the opening of business on the immediately following Business Day. Whenever
any payment to Bank under the Loan Documents would otherwise be due (except by
reason of acceleration) on a date that is not a Business Day, such payment
shall instead be due on the next Business Day, and additional fees or
interest, as the case may be, shall accrue and be payable for the period of
such extension.

         2.4 FEES. Borrower shall pay to Bank the following:

                   (a) FACILITY FEE. A Facility Fee equal to Thirty Thousand
and No/100 Dollars ($30,000), which fee shall be due on the Closing Date and

customary fees and out-of-pocket expenses for Bank's audits of Borrower's
Accounts, and for each appraisal of Collateral and financial analysis and
examination of Borrower performed from time to time by Bank or its agents;

                   (c) BANK EXPENSES. Upon demand from Bank, including,
without limitation, upon the date hereof, all Bank Expenses incurred through
the date hereof, including reasonable attorneys' fees and expenses, and, after
the date hereof, all Bank Expenses, including reasonable attorneys' fees and
expenses, as and when they become due.

         2.5 ADDITIONAL COSTS. In case any law, after the date hereof, any
regulation, treaty or official directive or the interpretation or application
thereof by any court or any governmental authority charged with the
administration thereof or the compliance with any guideline or request of any
central bank or other governmental authority (whether or not having the force
of law):

                   (a) subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or
otherwise with respect to the transactions contemplated hereby (except for
taxes on the overall net income of Bank imposed by the United States of
America or any political subdivision thereof);

                   (b) imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, Bank: or

                   (c) imposes upon Bank any other condition with respect to
its performance under this Agreement, and the result of any of the foregoing
is to increase the cost to Bank, reduce the income receivable by Bank or
impose any expense upon Bank with respect to the Obligations, Bank shall
notify Borrower thereof within one hundred eighty (180) days of Bank incurring
any such reduced income or increased cost or expense. Borrower agrees to pay
to Bank the amount of such increase in cost, reduction in income or additional
expense as and when such cost, reduction or expense is incurred or determined,
upon presentation by Bank of a statement of the amount and setting forth
Bank's calculation thereof, all in reasonable detail, which statement shall be
deemed true and correct absent manifest error.

         2.6 TERM. Except as otherwise set forth herein, this Agreement shall
become effective on the Closing Date and, subject to SECTION 12.7, shall
continue in full force and effect for a term ending on the Term Maturity Date.
Notwithstanding the foregoing, Bank shall have the right to terminate its
obligation to make Credit Extensions under this Agreement immediately and
without notice upon the occurrence and during the continuance of an Event of
Default.

continuing security interest in all presently existing and hereafter acquired
or arising Collateral and all proceeds thereof, in order to secure prompt
payment of any and all Obligations and in order to secure prompt performance
by Borrower of each of its covenants and duties under the Loan Documents.
Except as set forth in the Schedule, such security interest constitutes a
valid, first priority security interest in the presently existing Collateral,
and will constitute a valid, first priority security interest in Collateral
acquired after the date hereof. Borrower acknowledges that following the
occurrence and during the continuance of an Event of Default hereunder Bank
may place a "hold" on any deposit account pledged as Collateral to secure the
Obligations. Notwithstanding termination of this Agreement, Bank's Lien on the
Collateral shall remain in effect for so long as any Obligations are
outstanding.

         4.2 DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Borrower shall
from time to time execute and deliver to Bank, at the request of Bank, all
Negotiable Collateral, all financing statements and other documents that Bank
may reasonably request, in form satisfactory to Bank to perfect and continue
perfected Bank's security interest in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

         4.3 RIGHT TO INSPECT. Bank (through any of its officers, employees,
or agents) shall have the right, upon reasonable prior notice, from time to
time during Borrower's usual business hours, to inspect Borrower's Books and
to make copies thereof and to check, test, and appraise the Collateral in
order to verify Borrower's financial condition or the amount, condition of, or
any other matter relating to, the Collateral.

5.       REPRESENTATIONS AND WARRANTIES

         Borrower represents and warrants as follows:

         5.1 DUE ORGANIZATION AND QUALIFICATION. Borrower and each Subsidiary
is a corporation duly existing and in good standing under the laws of its
state of incorporation and qualified and licensed to do business in, and is in
good standing in Texas, and in any other state in which the conduct of its
business or its ownership of property requires that it be so qualified where
the failure to so qualify would result in a Material Adverse Effect.

         5.2 DUE AUTHORIZATION: NO CONFLICT. The execution, delivery, and
performance of the Loan Documents are within Borrower's powers, have been duly
authorized and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor
will they constitute an event of default under any material


                                     11

<PAGE>

                                                                   EXHIBIT 10.13

agreement to which Borrower is a party or by which Borrower is bound. Borrower
is not in default under any agreement to which it is a party or by which it is
bound, which default could have a Material Adverse Effect.

         5.3 NO PRIOR ENCUMBRANCES. Borrower has good and indefeasible title
to the Collateral free and clear of Liens, except for Permitted Liens.

         5.4 MERCHANTABLE INVENTORY. All Inventory is in all material respects
of good and marketable quality, free from all material defects.

         5.5 INTELLECTUAL PROPERTY. Borrower is the owner of the Patents,
Trademarks, Copyrights and Mask Works subject to licenses granted by Borrower
to its customers in the ordinary course of business. To Borrower's knowledge,
each of the Patents is valid and enforceable, and no part of the Intellectual
Property Collateral has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of the Intellectual Property
Collateral violates the rights of any third party. Except for and upon the
filing with the United States Patent and Trademark Office with respect to the
Patents and Trademarks and the Register of Copyrights with respect to the
Copyrights and Mask Works necessary to perfect the security interests created
hereunder, and except as has been already made or obtained, no authorization,
approval or other action by, and no notice to or filing with, any United
States governmental authority or United States regulatory body is required
either (i) for the grant by Borrower of the security interest granted hereby
or for the execution, delivery or performance of Loan Documents by Borrower in
the United States or (ii) for the perfection in the United States or the
exercise by Bank of its rights and remedies hereunder.

         5.6 NAME: LOCATION OF CHIEF EXECUTIVE OFFICE. Except as disclosed in
the Schedule, Borrower has not done business and will not without at least
thirty (30) days prior written notice to Bank do business under any name other
than that specified on the signature page hereof. The chief executive office
of Borrower is located at the address indicated in SECTION 10 hereof.

         5.7 LITIGATION. Except as set forth in the Schedule, there are no
actions or proceedings pending, or, to Borrower's knowledge, threatened by or
against Borrower or any Subsidiary before any court or administrative agency
in which an adverse decision could have a Material Adverse Effect on
Borrower's interest or Bank's security interest in the Collateral.

         5.8 NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS. All
consolidated financial statements related to Borrower and any Subsidiary that
have been delivered by Borrower to Bank fairly present in all material
respects Borrower's consolidated financial condition as of the date thereof
and Borrower's consolidated results of operations for the period then ended.
There has not been a material adverse change in the consolidated financial
condition of Borrower since the date of the most recent of such financial
statements submitted to Bank on or about the Closing Date.

         5.9 SOLVENCY. The fair saleable value of Borrower's assets (including
goodwill minus disposition costs) exceeds the fair value of its liabilities;
the Borrower is not left with

                                     12

<PAGE>

                                                                   EXHIBIT 10.13

unreasonably small capital after the transactions contemplated by this
Agreement; and Borrower is able to pay its debts (including trade debts) as
they mature.

         5.10 REGULATORY COMPLIANCE. Borrower and each Subsidiary has met the
minimum funding requirements of ERISA with respect to any employee benefit
plans subject to ERISA. No event has occurred resulting from Borrower's
failure to comply with ERISA that is reasonably likely to result in Borrower's
incurring any liability that could have a Material Adverse Effect. Borrower is
not an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940. Borrower is
not engaged principally, or as one of its important activities, in the
business of extending credit for the purpose of purchasing or carrying margin
stock (within the meaning of Regulations G, T and U of the Board of Governors
of the Federal Reserve System). Borrower has complied with all the provisions
of the Federal Fair Labor Standards Act. Borrower has not violated any
statutes, laws, ordinances or rules applicable to it, violation of which could
have a Material Adverse Effect.

sprinklers, and all other hazards and risks, and in-such amounts, as
ordinarily insured against by other owners in similar businesses conducted in
the locations where Borrower's business is conducted on the date hereof.
Borrower shall also maintain insurance relating to Borrower's ownership and
use of the Collateral in amounts and of a type that are customary, to
businesses similar to Borrower's.

                           (b) All such policies of insurance shall be in such
form, with such companies, and in such amounts as are reasonably satisfactory
to Bank. All such policies of property insurance shall contain a lender's loss
payable endorsement, in a form satisfactory to Bank, showing Bank as an

the Bank as an additional insured, and shall specify that the insurer must
give at least fifteen (15) days notice to Bank before canceling its policy for
any reason. At Bank's request, Borrower shall deliver to Bank certified copies

                           (b) Borrower shall execute and deliver such

obligation, to take, at Borrower's sole expense, any actions that Borrower is
required under this SECTION 6.7 to take but which Borrower fails to take,

after the date hereof, Borrower shall deliver to Bank a Subordination of Lien
from each Person who leases real property to Borrower in form and substance
acceptable to Bank. Borrower acknowledges and agrees that no Credit Extensions
will be made if such subordinations are not delivered by the date set forth

7.       NEGATIVE COVENANTS

         Borrower covenants and agrees that, so long as any Credit Extension

Norris or Graham Glass ceases to be an employee or director of Borrower and

provided in the Stock Purchase Agreement and (ii) the Put (as defined in that
certain Warrant Subscription Agreement ("Subscription Agreement") between
Bank, Borrower, and Borrower's shareholders of even date herewith) from Bank
and as provided in the Subscription Agreement. Borrower will not, without the
prior written consent of Bank, supplement, amend, modify or waive in any way
any provision of the Stock Purchase Agreement. Borrower agrees and
acknowledges that the foregoing right of Borrower to purchase the Put Shares
is not a waiver of any Event of Default which might be created by such

other payments set forth in the first sentence of this SECTION 7.6 and as
otherwise set forth in SECTION 7.8 below.

         7.7 INVESTMENTS. Directly or indirectly acquire or own, or make any

Agreement, directly or indirectly enter into or permit to exist any material
transaction with any Affiliate of Borrower except for transactions that are in
the ordinary course of Borrower's business, upon fair and reasonable terms
that are no less favorable to Borrower than would be obtained in an arm's
length transaction with a nonaffiliated Person. Borrower agrees and
acknowledges that right of Borrower to purchase the Put Shares pursuant to and
in accordance with SECTION 7.6 above is not a waiver of any Event of Default
which might be created by such purchase, other than the general prohibition on
any material transaction with an Affiliate of Borrower set forth in the first
sentence of this SECTION 7.8 and as otherwise set forth in SECTION 7.6 above.

         7.9 INTELLECTUAL PROPERTY AGREEMENTS. Permit the inclusion in any

hereof and such other locations of which Borrower gives Bank prior written
notice and as to which Borrower signs and files a financing statement where
needed to perfect Bank's security interest.

         7.12 COMPLIANCE. Become an "investment company" or a company
controlled by an "investment company," within the meaning of the Investment
Company Act of 1940, or become principally engaged in, or undertake as one of

of the foregoing.

         7.13 ABANDONMENT OF INTELLECTUAL PROPERTY. If an Event of Default

Mask Works to be abandoned, forfeited or dedicated to the public without the

calendar days of when due, any of the Obligations.

         8.2  COVENANT DEFAULT.

                           (a) If Borrower fails to perform any obligation
under SECTIONS 6.3, or 6.7 or violates any of the covenants contained in
Article 7 of this Agreement, or

                           (b) If Borrower fails or neglects to perform, keep,
or observe any other material term, provision, condition, covenant, or
agreement contained in this Agreement, in any of the Loan Documents, or in any
other present or future agreement between Borrower and Bank and as to any
default under such other term, provision, condition, covenant or agreement
that can be cured, has failed to cure such default within ten (10) days after
the occurrence thereof;

provided, however, that if the default cannot by its nature be cured within
the ten (10) day period or cannot after diligent attempts by Borrower be cured
within such ten (10) day period, and such default is likely to be cured within
a reasonable time, then Borrower shall have an additional reasonable period
(which shall not in any case exceed thirty (30) days) to attempt to cure such
default, and within such reasonable time period the failure to have cured such
default shall not be deemed an Event of Default (provided that no Credit
Extensions will be required to be made during such cure period).

         8.3 MATERIAL ADVERSE CHANGE. If there (i) occurs a material adverse
change in the business, operations, or condition (financial or otherwise) of

or priority of Bank's security interests in the Collateral;

         8.4 ATTACHMENT. If any material portion of Borrower's assets is
attached, seized, subjected to a writ or distress warrant, or is levied upon,
or comes into the possession of any trustee, receiver or person acting in a
similar capacity and such attachment, seizure, writ or distress warrant or
levy has not been removed, discharged or rescinded within thirty (30) days, or
if Borrower is enjoined, restrained, or in any way prevented by court order
from continuing to conduct all or any material part of its business affairs,
or if a judgment or other claim becomes a lien or encumbrance upon any
material portion of Borrower's assets, or if a notice of lien, levy, or
assessment is filed of record with respect to any of Borrower's assets by the
United States Government, or any department, agency, or instrumentality
thereof, or by any state, county, municipal, or governmental agency, and the
same is not paid within thirty (30) days after Borrower receives notice
thereof, provided that none of the foregoing shall constitute an Event of
Default where such action or event is stayed or an adequate bond has been
posted pending a good faith contest by Borrower (provided that no Credit
Extensions will be required to be made during such cure period).

         8.5 INSOLVENCY. If Borrower becomes insolvent, or if an Insolvency
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is
commenced against Borrower and is not dismissed or stayed within forty-five
(45) days (provided that no Credit Extensions will be made prior to the
dismissal of such Insolvency Proceeding).

         8.6 OTHER AGREEMENTS. If there is a default in any agreement to which
Borrower is a party with a third party or parties resulting in the exercise of
a right by such third party or parties to accelerate the maturity of any
Indebtedness in an amount in excess of One Hundred Thousand and No/100 Dollars
($100,000.00) or that could have a Material Adverse Effect;

         8.7 SUBORDINATED DEBT. If Borrower makes any payment on account of

dated as of February 9, 1998 (the "Senior Loan Agreement")) occurs under the
Senior Loan Agreement;

         8.9  JUDGMENTS. If a judgment or judgments for the payment of money in
an amount, individually or in the aggregate, of at least One Hundred Thousand
and No/100 Dollars ($100,000.00) shall be rendered against Borrower and shall
remain unsatisfied and unstayed for a period of ten (10) days (provided that no
Credit Extensions will be made prior to the satisfaction or stay of such
judgment); or

         8.10 MISREPRESENTATIONS. If any material misrepresentation or material
misstatement exists now or hereafter in any warranty or representation set forth
herein or in any certificate or writing delivered to Bank by Borrower or any
Person acting on Borrower's behalf pursuant to this Agreement or to induce Bank

of which are authorized by Borrower:

                     (a) Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due
and payable (provided that upon the occurrence of an Event of Default
described in SECTION 8.5 all Obligations shall become immediately due and
payable without any action by Bank);

                     (b) Cease advancing money or extending credit to or for
the benefit of Borrower under this Agreement or under any other agreement

                     (c) Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                     (d) Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to
protect its security interest in the Collateral. Borrower agrees to assemble
the Collateral if Bank so requires, and to make the Collateral available to
Bank as Bank may designate. Borrower authorizes Bank 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 which in Bank's determination appears to be
prior or superior to its security interest and to pay all expenses incurred
in connection therewith. With respect to any of Borrower's premises, Borrower
hereby grants Bank a license to enter such premises and to occupy the same,
without charge in order to exercise any of Bank's rights or remedies provided
herein, at law, in equity, or otherwise;

                     (e) Without notice to Borrower, set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank,

Borrower held by Bank;

                     (f) Skip, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner
provided for herein) the Collateral. Bank is hereby granted a non-exclusive,
royalty-free license or other right, solely pursuant to the provisions of
this SECTION 9.1, to use, without charge, Borrower's labels, patents,
copyrights,

mask works, 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, in connection with
Bank's exercise of its rights under this SECTION 9.1, Borrower's rights under
all licenses and all franchise agreements shall inure to Bank's benefit;

                     (g) 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 Borrower's premises)
as Bank determines is commercially reasonable, and apply the proceeds thereof
to the Obligations in whatever manner or order it deems appropriate;

                     (h) Bank may credit bid and purchase at any public sale,
or at any private sale as permitted by law; and

                     (i) Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

                     (j) Bank shall have a non-exclusive, royalty-free
license to use the Intellectual Property Collateral to the extent reasonably
necessary, to permit Bank to exercise its rights and remedies upon the
occurrence of an Event of Default.

         9.2  POWER OF ATTORNEY. Effective only upon the occurrence and during
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the Accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; (f) modify, in its sole
discretion, any intellectual property security agreement entered into between
Borrower and Bank without first obtaining Borrower's approval of or signature to
such modification by amending Exhibit A, Exhibit B, Exhibit C and Exhibit D,
thereof, as appropriate, to include reference to any right, title or interest in
any Copyrights, Patents, Trademarks, Mask Works acquired by Borrower after the
execution hereof or to delete any reference to any right, title or interest in
any Copyrights, Patents, Trademarks, or Mask Works in which Borrower no longer
has or claims any right, title or interest; (g) file, in its sole discretion,
one or more financing or continuation statements and amendments thereto,
relative to any of the Collateral without the signature of Borrower where
permitted by law; and (h) transfer the Intellectual Property Collateral into the
name of Bank or a third party to the extent permitted under the Code provided
Bank may exercise such power of attorney to sign the name of Borrower on any of
the documents described in SECTION 4.2 regardless of whether an Event of Default
has occurred. The appointment of Bank as Borrower's attorney in fact, and each
and every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide Credit Extensions hereunder is terminated.

         9.3  ACCOUNTS COLLECTION. Upon the occurrence and during the
continuance of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of
such Account. Borrower shall collect all amounts owing to Borrower for Bank,
receive in trust all payments as Bank's trustee, and if requested or required
by Bank, immediately deliver such payments to Bank in their original form as
received from the account debtor, with proper endorsements for deposit.

         9.4  BANK EXPENSES. If Borrower fails to pay any amounts or furnish
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the
following: (a) make payment of the same or any part thereof; (b) set up such
reserves under the Term Loan as Bank deems necessary to protect Bank from the
exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in SECTION 6.6 of this Agreement, and take any
action with respect to such policies as Bank deems prudent. Any amounts so
paid or deposited by Bank shall constitute Bank Expenses, shall be
immediately due and payable, and shall bear interest at the then applicable
rate hereinabove provided, and shall be secured by the Collateral. Any
payments made by Bank shall not constitute an agreement by Bank to make
similar payments in the future or a waiver by Bank of any Event of Default
under this Agreement.

         9.5  BANK'S LIABILITY FOR COLLATERAL. So long as Bank complies with
reasonable banking practices, Bank 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 whomsoever.
All risk of loss, damage or destruction of the Collateral shall be borne by
Borrower.

         9.6  REMEDIES CUMULATIVE. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies, not expressly set forth
herein, and as provided under the Code, by law, or in equity. No exercise by
Bank of one right or remedy shall be deemed an election, and no waiver by
Bank of any Event of Default on Borrower's part shall be deemed a continuing
waiver. No delay by Bank shall constitute a waiver, election, or acquiescence
by it. No waiver by Bank shall be effective unless made in a written document
signed on behalf of Bank and then shall be effective only in the specific
instance and for the specific purpose for which it was given.

         9.7  DEMAND: PROTEST. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment,
notice of any default, notice of intent to accelerate, notice of
acceleration, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be
liable.
