                Borrower (pursuant to Section 2.1 hereof) and issue Letters of
                Credit (pursuant to Section 2.2 hereof) under a revolving line
                of credit (the "Revolving Credit") from time to time in amounts
                requested by Borrower up to an aggregate outstanding principal
                amount equal to the Committed Line less the face amount of all
                issued and outstanding Letters of Credit (including drawn but
                unreimbursed letters of credit). Subject to the terms and
                conditions of this Agreement, Borrower may borrow and reborrow
                under this Section 2.1.

                        2.2 Letters of Credit.

                                2.2.1 Issuance. Subject to, and upon the terms
                        and conditions contained herein, at the request of
                        Borrower, Bank agrees from time to time during the term
                        of this Agreement to issue Letters of Credit for the
                        account of Borrower containing terms and conditions
                        acceptable to Bank, provided however that no Letter of
                        Credit shall have an expiration date beyond ninety (90)
                        days from the Termination Date. Each draft paid by Bank
                        under a Letter of Credit shall be deemed an Advance
                        under the Revolving Credit and shall be repaid by
                        Borrower in accordance with the terms and conditions of
                        this Agreement applicable to such Advances; provided
                        however, that if the Revolving Credit is not available,
                        for any reason whatsoever, at the time any draft is paid
                        by Bank, or if Advances are not available under the
                        Revolving Credit at such time due to any limitation on
                        borrowings set forth herein, then the full amount of
                        such draft shall be immediately due and payable,
                        together with interest thereon, from the date such
                        amount is paid by Bank to the date such amount is fully
                        repaid by Borrower, at the rate of interest applicable
                        to Advances. In such event, Borrower agrees that Bank,
                        at Bank's sole discretion, may debit Borrower's deposit
                        account with Bank for the amount of any such draft.

                                2.2.2 Letter of Credit Sublimit. No Letters of
                        Credit shall be issued unless, on the date of the
                        proposed issuance of any Letter of Credit, the Advances
                        available to Borrower under the Revolving Credit are
                        equal to one hundred percent (100%) of the face amount
                        of such Letters of Credit. Except in Bank's discretion,
                        the amount of all Letter of Credit Obligations shall not
                        at any time exceed Three Million Five Hundred Thousand
                        and 00/100 Dollars ($3,500,000).

                                2.2.3 Letter of Credit Agreement. Each Letter of
                        Credit shall be subject to the additional terms and
                        conditions of the Letter of Credit Agreement and related
                        documents, if any, required by Bank in connection with
                        the issuance thereof (each, a "Letter of Credit
                        Agreement").

                                2.2.4 Letter of Credit Fees. Borrower shall pay
                        to Bank fees upon the issuance or amendment of each
                        Letter of Credit and upon the payment by Bank of each
                        draft under any Letter of Credit determined in
                        accordance with Bank's standard fees and charges in
                        effect at the time any Letter of Credit is issued or
                        amended or any draft is paid.

                                2.2.5 Termination of Revolving Credit. Upon
                        termination of the Revolving Credit, Borrower shall
                        provide Bank cash security for all issued and
                        outstanding Letters of Credit.



                        2.3 Manner of Borrowing. Borrower may request an Advance
                under the Revolving Credit only after delivery to Bank of a
                Request for Advance executed by an authorized officer of
                Borrower, subject to the following: (a) each such Request for
                Advance shall set forth the information required on the Request
                for Advance form annexed hereto as Exhibit D (or such other
<PAGE>   9

                form as acceptable to Bank), including, without limitation, the
                proposed amount and date of such Advance, which date must be a
                Business Day; (b) each such Request for Advance shall be
                delivered to Bank by 3:00 p.m. California time on the proposed
                date of Advance; and (c) a Request for Advance, once delivered
                to Bank, shall not be revocable by Borrower.

                                2.3.1 Bank may make Advances under the Revolving
                        Credit upon the telephonic or facsimile request of
                        Borrower, which Borrower shall confirm in writing by
                        delivering to Bank, on or before 11:00 a.m. on the next
                        Business Day following such Advance with a duly executed
                        Request for Advance and Borrower shall indemnify and
                        hold Bank harmless for any damages or loss suffered by
                        Bank as a result of reliance on such telephonic or
                        facsimile request.

                        2.4 Interest. Borrower shall pay interest to Bank on the
                outstanding and unpaid principal amount of the Revolving Credit
                at a floating rate per annum equal to the Base Rate.

                                2.4.1 Adjusted Rate. Any change in the interest
                        rate resulting from a change in the Base Rate shall be
                        effective as of the opening of business on the day on
                        which such change in the Base Rate becomes effective.

                                2.4.2 Default Rate. From and after the
                        Termination Date, Advances under the Revolving Credit
                        shall bear interest at a rate equal to three percentage
                        points (3%) more than the interest rate that would have
                        been applicable hereunder. Anything herein to the
                        contrary notwithstanding, interest at the default rate
                        shall be due and payable on demand but shall accrue from
                        the Termination Date until all Advances are paid in
                        full.

                        2.5 Repayment Terms. Interest only shall be due and
                payable on the unpaid principal balance of the Revolving Credit,
                without claim, notice, presentment or demand, in consecutive
                monthly installments on the first (1st) day of each month
                commencing on the first (1st) day of the first (1st) full
                calendar month following the Funding Date. 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.

                                2.5.1 Application of Payments. Each payment
                        received by Bank shall be credited as of its due date,
                        without regard to its date of receipt by Bank, first to
                        interest accrued and unpaid as of such due date and the
                        remainder to principal, and interest shall cease upon
                        the principal so credited. All interest calculations
                        shall be on a basis of a three hundred and sixty
                        (360)-day year for the actual number of days elapsed.
                        Daily interest shall consist of the product of the
                        outstanding principal balance of the Revolving Credit
                        times the annual interest rate then in effect divided by
                        360, then multiplied by the number of days for which the
                        daily interest calculation is made. Interest paid for
                        any partial month shall be prorated based on a thirty
                        (30)-day month and the actual number of day elapsed.
                        Interest shall be compounded monthly.



                                2.5.2 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 shall be immediately
                        applied to conditionally reduce Obligations, but shall
                        not be considered a payment on account 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
<PAGE>   10

                        noon California time shall be deemed to have been
                        received by Bank as of the opening of business on the
                        immediately following Business Day.

                                2.5.3 Method of Payment. Borrower shall make
                        each payment under this Agreement when due in lawful
                        money of the United States to Bank at its address set
                        forth herein, or at such other location as directed by
                        Bank in writing, in immediately available funds.
                        Borrower hereby authorizes Bank, if and to the extent
                        payment is not made when due under this Agreement, to
                        charge from time to time against any deposit account of
                        Borrower with Bank any amount so due. Whenever any
                        payment to be made under this Agreement shall be stated
                        to be due on a day other than a Business Day, such
                        payment shall be made on the next succeeding Business
                        Day, and such extension of time shall in such case be
                        included in the computation of the payment of interest.

                        2.6 Revolving Credit Fee. Borrower agrees to pay to Bank
                a commitment fee equal to the rate of one quarter (1/4) of one
                percent (0.25%) per annum of the Committed Line, payable on the
                Closing Date and each anniversary of such date thereafter.

                        2.7 Overadvances. If, at any time or for any reason, the
                amount of Obligations owed by Borrower to Bank pursuant to
                Section 2.1 of this Agreement is greater than the Committed
                Line, Borrower shall immediately pay to Bank, in cash, the
                amount the Obligations exceed the Committed Line.

                        2.8 Termination of Revolving Credit. The Revolving
                Credit shall terminate on the Termination Date, at which time
                all unpaid principal, all unpaid and accrued interest, and all
                other amounts due under the Revolving Credit shall be
                immediately due and payable.

                        2.9 Statements. With respect to each Advance, Bank is
                hereby authorized to note the date, principal amount, and
                interest rate applicable thereto, and any payments made thereon,
                on its books and records (either manually or by electronic
                entry), which notations shall be conclusive evidence of the
                information noted in the absence of manifest error. A failure by
                Bank to record any such information shall not impair the
                Borrower's liability to make payment when due. Bank shall render
                to Borrower each month a statement setting forth the balance in
                Borrower's loan account maintained by Bank for Borrower pursuant
                to the provisions of this Agreement, including principal,
                interest, fees, costs and expenses. Each such statement shall be
                subject to subsequent adjustment by Bank but shall, absent
                manifest errors or omissions, be considered correct and deemed
                accepted by Borrower and conclusively binding upon Borrower as
                an account stated except to the extent that Bank receives a
                written notice from Borrower of any specific exceptions of
                Borrower thereto within thirty (30) days after the date such
                statement has been mailed by Bank. Until such time as Bank shall
                have rendered to Borrower a written statement as provided above,
                the balance in Borrower's loan account shall be presumptive
                evidence of the amounts due and owing to Bank by Borrower.

                        2.10 Ratification of Obligations. Borrower ratifies and
                reaffirms the Obligations under the Loan Agreement, which are
                currently outstanding, as of the Closing Date, in the principal
                amount of One Million Five Hundred Twenty-Five Thousand and
                00/100 Dollars ($1,525,000.00) without setoff, defense, or
                counterclaim. Borrower agrees fully and faithfully to pay,
                perform and discharge, as and when payment, performance and
                discharge are due, all of the Obligations under the Loan
                Agreement, as amended hereby. By executing this Agreement,
                Borrower acknowledges and agrees that except as supplemented or
                modified hereby, the Loan Documents are and shall remain in full
                force and effect.

<PAGE>   11



                        3.1 Financial Examination and Appraisal Fees. Borrower
                shall pay Bank's 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.

                        3.2 Bank Expenses. Borrower shall pay upon the date
                hereof, all Bank Expenses incurred through the Closing Date,
                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.

                        3.3 Additional Costs. In case any change in any law,
                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), in each case after the date of this Agreement: (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 any loans, Bank shall
                notify Borrower thereof. 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.

                                   ARTICLE V
                          CREATION OF SECURITY INTEREST

                        5.1 Grant of Security Interest. In order to secure
                prompt repayment 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, Borrower grants and pledges
                to Bank a continuing security interest in all presently existing
                and hereafter acquired or arising Collateral. Except as set
                forth in the Exhibit B, and for Permitted Liens, 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., to the extent that a security interest
                in such Collateral can be perfected by the filing of a financing
                statement or, in the case of Collateral consisting of
                instruments, documents, chattel paper or certificated
                securities, to the extent that Bank takes possession of such
                Collateral. Borrower acknowledges that Bank may place a "hold"
                on any deposit account pledged as Collateral to secure the
                Obligations. Bank agrees to execute and deliver to Borrower from
                time to time such subordination agreements as Borrower may
                request and as are necessary to give to other lenders which
                finance equipment for Borrower a first priority security
                interest in the equipment financed so long as the Liens and the
                Indebtedness incurred with respect to such equipment financing
                are permitted under this Agreement. Notwithstanding the
                foregoing, the security interest granted herein shall not extend
                to and the term "Collateral" shall not include any property,
                rights or licenses to the extent the granting of a security
                interest therein (a) would be contrary to applicable law; or (b)
                is prohibited by or would constitute a default under any
                agreement or document governing such property, rights or
                licenses (but only to the extent such prohibition is enforceable
                under applicable law, including without limitation Section 9318
                of the Code); provided that immediately and automatically upon
                the ineffectiveness, lapse or termination of any such
                prohibition or restriction, the Collateral shall include such
                property, rights or licenses, and Borrower shall be deemed to
                have granted a security interest in all such rights and
                interests as if such prohibition or restriction had never been
                in effect. Notwithstanding termination of this Agreement, Bank's
                Lien on the Collateral shall remain in effect for so long as any
                Obligations are outstanding.

                        5.2 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 interests in the Collateral and in order to
                fully consummate all of the transactions contemplated under the
                Loan Documents.

                        5.3 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.
                Notwithstanding any provision of this Agreement to the contrary,
                except upon the occurrence and during the continuation of an
                Event of Default, Borrower shall not be required to disclose,
                permit the inspection, examination, copying or
<PAGE>   13

                making extracts of, or discuss, any document, information or
                other matter that (a) constitutes non-financial trade secrets or
                non-financial proprietary information, or (b) the disclosure of
                which to Bank, or their designated representative, is then
                prohibited by (i) law, or (ii) an agreement binding on the
                Borrower that was not entered into by the Borrower for the
                primary purpose of concealing information from the Bank.





                                   ARTICLE VI
                         REPRESENTATIONS AND WARRANTIES



               Borrower represents and warrants as follows:



                        6.1 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, any state in which the conduct of its business or
                its ownership of property requires that it be so qualified.

                        6.2 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 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.

                        6.3 No Prior Encumbrances. Borrower has good and valid
                title to all property and assets purported to be owned by it,
                including those assets identified on the Financial Statements
                most recently delivered by Borrower to and accepted by Bank,
                free and clear of all security interests, liens, mortgages, or
                other encumbrances, except for Permitted Liens.

                        6.4 Bona Fide Accounts. Borrower's accounts are bona
                fide existing obligations. The property giving rise to such
                accounts has been delivered to the account debtor or to the
                account debtor's agent for immediate shipment to and
                unconditional acceptance by the account debtor. Borrower has not
                received notice of actual or imminent Insolvency Proceeding of
                any account debtor.

                        6.5 Merchantable Inventory. All inventory not otherwise
                disclosed in the Financial Statements is in all material
                respects of good and marketable quality, free from all material
                defects.

                        6.6 Name; Location of Chief Executive Office. Borrower
                has not done 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 Article XII
                hereof.

                        6.7 Litigation. Except as set forth in Exhibit E, there
                are no actions or proceedings pending 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. Borrower does not have knowledge of any such pending
                or threatened actions or proceedings.

<PAGE>   14


                        6.8 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.

                        6.9 Solvency. Borrower is solvent and able to pay its
                debts (including trade debts) as they mature.

                        6.10 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 the 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.

                        6.11 Environmental Condition. None of Borrower's or any
                Subsidiary's properties or assets has ever been used by Borrower
                or any Subsidiary or, to the best of Borrower's knowledge, by
                previous owners or operators, in the disposal of, or to produce,
                store, handle, treat, release, or transport, any hazardous waste
                or hazardous substance other than in accordance with applicable
                law; to the best of Borrower's knowledge, none of Borrower's
                properties or assets has ever been designated or identified in
                any manner pursuant to any environmental protection statute as a
                hazardous waste or hazardous substance disposal site, or a
                candidate for closure pursuant to any environmental protection
                statute; no lien arising under any environmental protection
                statute has attached to any revenues or to any real or personal
                property owned by Borrower or any Subsidiary; and neither
                Borrower nor any Subsidiary has received a summons, citation,
                notice, or directive from the Environmental Protection Agency or
                any other federal, state or other governmental agency concerning
                any action or omission by Borrower or any Subsidiary resulting
                in the releasing, or otherwise disposing of hazardous waste or
                hazardous substances into the environment.

                        6.12 Taxes. Borrower and each Subsidiary has filed or
                caused to be filed all tax returns required to be filed, and has
                paid, or has made adequate provision for the payment of, all
                taxes reflected therein.

                        6.13 Subsidiaries and Ownership of Stock. Set forth in
                Exhibit F is a complete and accurate list of the Subsidiaries of
                Borrower, showing the jurisdiction of incorporation of each and
                showing the percentage of Borrower's ownership of the
                outstanding stock of each Subsidiary. All of the outstanding
                capital stock of each such Subsidiary has been validly issued,
                is fully paid and nonassessable, and is owned by Borrower free
                and clear of all Liens.

                        6.14 Government Consents. Borrower and each Subsidiary
                has obtained all consents, approvals and authorizations of, made
                all declarations or filings with, and given all notices to, all
                governmental authorities that are necessary for the continued
                operation of Borrower's business as currently conducted.

                        6.15 Full Disclosure. No representation, warranty or
                other statement made by Borrower in any certificate or written
                statement furnished to Bank contains any untrue
<PAGE>   15

                statement of a material fact or omits to state a material fact
                necessary in order to make the statements contained in such
                certificates or statements not misleading.



                                  ARTICLE VII
                              AFFIRMATIVE COVENANTS

               Borrower covenants and agrees that, until payment in full of all
outstanding Obligations, and for so long as Bank may have any commitment to make
an Advance hereunder, Borrower shall do all of the following:

                        7.1 Good Standing. Borrower shall maintain its and each
                of its Subsidiaries' corporate existence and good standing in
                its jurisdiction of incorporation and maintain qualification in
                each jurisdiction in which the failure to so qualify could have
                a Material Adverse Effect. Borrower shall maintain, and shall
                cause each of its Subsidiaries to maintain, to the extent
                consistent with prudent management of Borrower's business, in
                force all licenses, approvals and agreements, the loss of which
                could have a Material Adverse Effect.

                        7.2 Government Compliance. Borrower shall meet, and
                shall cause each Subsidiary to meet, the minimum funding
                requirements of ERISA with respect to any employee benefit plans
                subject to ERISA. Borrower shall comply, and shall cause each
                Subsidiary to comply, with all statutes, laws, ordinances and
                government rules and regulations to which it is subject,
                noncompliance with which could have a Material Adverse Effect or
                a material adverse effect on the Collateral or the priority of
                Bank's Lien on the Collateral.

                        7.3 Financial Statements. Borrower shall deliver to
                Bank:

                                7.3.1 Quarterly Reports. As soon as available
                        and in any event within forty-five (45) days after the
                        end of each fiscal quarter, Borrower shall deliver its
                        Form 10-Q Quarterly Report filed pursuant to the
                        Securities Exchange Act of 1934, as amended from time to
                        time, and any successor statute, and the rules and
                        regulations issued thereunder ("Exchange Act"), all as
                        the same may be in effect at the time.

                                7.3.2 Annual Report. As soon as available and in
                        any event within ninety (90) days after the end of each
                        fiscal year, Borrower shall deliver its Form 10-K Annual
                        Report filed pursuant to the Exchange Act.

                        7.4 Compliance Certificate. Borrower shall deliver to

                        of such policies of insurance and evidence of the
                        payments of all premiums therefor. All proceeds payable
                        under any such policy shall, at the option of Bank, be
                        payable to Bank to be applied on account of the

                applicable Environmental Laws, where the failure to do so could
                have a Material Adverse Effect upon the business, operations,
                condition (financial or otherwise) performance or properties of
                Borrower, of any of its Subsidiaries, or could have a Material
                Adverse Effect upon Borrower's, or any of its Subsidiaries',
                ability to perform their respective obligations under this
                Agreement or any of the other Loan Documents, or could
                materially adversely affect the enforceability of this Agreement
                or any of the other Loan Documents.

                                7.10.1 Promptly notify Bank, in writing, as soon
                        as Borrower becomes aware of any condition or

                        Environmental Laws by either Borrower, or any of its
                        Subsidiaries, or of any circumstance or condition which
                        requires or may require, a material financial
                        contribution by Borrower, or any of its Subsidiaries, or

                                EVENTS OF DEFAULT

                Any one or more of the following events shall constitute an
"Event of Default" by Borrower under this Agreement:

                        10.1 Payment Default. If Borrower fails to pay the
                principal of, or any interest on, any Advances when due and
                payable; or fails to pay any portion of any other Obligations
                not constituting such principal or interest, including without
                limitation Bank Expenses when due;

                        10.2 Covenant Default. If Borrower fails to perform any
                obligation hereunder or violates any of the covenants contained
                in this Agreement, or 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) Business Days
                after Borrower receives notice thereof or any officer of
                Borrower becomes aware 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 Advances will be required to be made during such cure
                period);

                        10.3 Material Adverse Change. If there occurs a material
                adverse change in Borrower's business or financial condition, or
                if there is a material impairment of the prospect of repayment
                of any portion of the Obligations or a material impairment of
                the value or priority of Bank's security interests in the
                Collateral;

                        10.4 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 ten (10)
                Business 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 ten (10) Business 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 Advances will be required to be made
                during such cure period);

                        10.5 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 ten (10) Business Days (provided that
                no Advances will be made prior to the dismissal of such
                Insolvency Proceeding);

                        10.6 Change in Management. If there shall be any change
                in the management, ownership or control of Borrower, whether by
                reason of incapacity, death, resignation, termination or
                otherwise, which, in Bank's sole judgment, shall have a Material
                Adverse Effect upon the future prospects for the successful
                operation by Borrower, of its businesses as conducted before
                such change, or its ability to pay and perform its liabilities
                and obligations under this Agreement, the Indebtedness, or the
                Loan Documents
<PAGE>   21

                        10.7 Other Agreements. If there is a default in any
                agreement to which Borrower is a party with a third party or
                parties resulting in a right by such third party or parties,
                whether or not exercised, to accelerate the maturity of any
                Indebtedness in an amount in excess of One Hundred Thousand
                Dollars ($100,000) or that could have a Material Adverse Effect;

                        10.8 Subordinated Debt. If Borrower makes any payment on
                account of Subordinated Debt, except to the extent such payment
                is allowed under any subordination agreement entered into with
                Bank;

                        10.9 Judgments. If a judgment or judgments for the
                payment of money in an amount, individually or in the aggregate,
                of at least Two Hundred and Fifty Thousand and 00/100 Dollars
                ($250,000.00) shall be rendered against Borrower and shall
                remain unsatisfied and unstayed for a period of ten (10)
                Business Days (provided that no Advances will be made prior to
                the satisfaction or stay of such judgment);

                        10.10 Misrepresentations. If any material
                misrepresentation or material misstatement exists now or
                hereafter in any warranty or representation set forth herein or
                in any certificate delivered to Bank by any Responsible Officer
                pursuant to this Agreement or to induce Bank to enter into this
                Agreement or any other Loan Document; or

                        10.11 Guaranty. Any guaranty of all or a portion of the
                Obligations ceases for any reason to be in full force and
                effect, or any guarantor fails to perform any obligation under
                any guaranty of all or a portion of the Obligations, or any
                material misrepresentation or material misstatement exists now
                or hereafter in any warranty or representation set forth in any
                guaranty of all or a portion of the Obligations or in any
                certificate delivered to Bank in connection with such guaranty.

                           BANK'S RIGHTS AND REMEDIES

                        11.1 Rights and Remedies. Upon the occurrence and during
                the continuance of an Event of Default, Bank 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
                Borrower:

                                11.1.1 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 10.5 all Obligations shall
                        become immediately due and payable without any action by
                        Bank);

                                11.1.2 Cease advancing money or extending credit
                        to or for the benefit of Borrower under this Agreement
                        or under any other agreement between Borrower and Bank;

                                11.1.3 Demand that Borrower (a) deposit cash
                        with Bank in an amount equal to the amount of any
                        Letters of Credit remaining undrawn, as collateral
                        security for the repayment of any future drawings under
                        such Letters of Credit, and Borrower shall forthwith
                        deposit and pay such amounts, and (b) pay in advance all
                        Letters of Credit fees scheduled to be paid or payable
                        over the remaining term of the Letters of Credit;

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



<PAGE>   22

                                11.1.5 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, after reasonable notice, 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
                        owned premises, Borrower hereby grants Bank a license to
                        enter into possession of 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;

                                11.1.6 Without notice to Borrower set off and
                        apply to the Obligations any and all (a) balances and
                        deposits of Borrower held by Bank, or (b) indebtedness
                        at any time owing to or for the credit or the account of
                        Borrower held by Bank;

                                11.1.7 Ship, 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 license or other
                        right, solely pursuant to the provisions of this Section
                        11.1, to use, without charge, 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, in connection with Bank's exercise of
                        its rights under this Section 11.1, Borrower's rights
                        under all licenses and all franchise agreements shall
                        inure to Bank's benefit;

                                11.1.8 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
                        any proceeds to the Obligations in whatever manner or
                        order Bank deems appropriate;

                                11.1.9 Bank may credit bid and purchase at any
                        public sale; and

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

                        11.2 Attorneys' Fees and Costs. Borrower shall pay all
                attorneys' fees and costs and expenses, including court costs,
                incurred in connection with enforcement of the Loan Documents,
                or any amendment, modification, or supplement thereto, whether
                by negotiation, legal proceedings, or otherwise.

                        11.3 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; provided Bank may exercise such power of


<PAGE>   23

                attorney to sign the name of Borrower on any of the documents
                described in Section 5.2 upon an Event of Default. 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
                advances hereunder is terminated.

                        11.4 Accounts Collection. At any time from the date of
                this Agreement, 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 immediately deliver such payments to Bank in
                their original form as received from the account debtor, with
                proper endorsements for deposit.

                        11.5 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
                Revolving Credit 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 7.8 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.

                        11.6 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.

                        11.7 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 inconsistent herewith as provided under the
                UCC, 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.

                        11.8 Demand; Protest. Borrower waives demand, protest,
                notice of protest, notice of default or dishonor, notice of
                payment and nonpayment, notice of any default, 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.

                   CHOICE OF LAW; VENUE; AND JURY TRIAL WAIVER

                This Agreement and all transactions contemplated hereunder and/
or evidenced hereby shall be governed by, construed under, and enforced in
accordance with the internal laws of the State of California, without regard to
principles of conflicts of law. Each of Borrower and Bank hereby submits to the
exclusive jurisdiction of the state and Federal courts located in the County of

RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED
THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL

                                  ARTICLE XIV
                               GENERAL PROVISIONS

                        14.1 Successors and Assigns. This Agreement shall bind
                and inure to the benefit of the respective successors and
                permitted assigns of each of the parties; provided, however,
                that neither this Agreement nor any rights hereunder may be
                assigned by Borrower without Bank's prior written consent, which
                consent may be granted or withheld in Bank's sole discretion.
                Bank shall have the right without the consent of or notice to
                Borrower to sell, transfer, negotiate, or grant participation in
                all or any part of, or any interest in, Bank's obligations,
                rights and benefits hereunder.

                        14.2 Term. This Agreement shall become effective on the
                Closing Date and, subject to Section 14.2, shall continue in
                full force and effect for a term ending on the Termination Date.
                Notwithstanding the foregoing, this Agreement shall remain in
                full force and effect until terminated by notice, by either
                party. Notice of such termination shall be effectuated by
                mailing of a registered or certified letter not less than thirty
                (30) days prior to the effective date of such termination,
                addressed to the other party at the address set forth herein and
                the termination shall be effective as of the date so fixed in
                such notice. Notwithstanding the foregoing, should Borrower be
                in default of one or more of the provisions of this Agreement,
                Bank may terminate this Agreement at any time without notice.
                Notwithstanding the foregoing, should either Bank or Borrower
                become insolvent or unable to meet its debts as they mature, or
                fail, suspend, or go out


<PAGE>   25

                of business, the other party shall have the right to terminate
                this Agreement at any time without notice. On the date of
                termination all Obligations shall become immediately due and
                payable without notice or demand; no notice of termination by
                Borrower shall be effective until Borrower shall paid all
                Obligations to Bank in full. Notwithstanding termination, until
                all Obligations have been fully satisfied, Bank shall retain its
                security interest in all existing Collateral and Collateral
                arising thereafter, and Borrower shall continue to perform all
                of its Obligations. After termination and when Bank has received
                payment in full of Borrower's Obligations to Bank, Bank shall
                reassign to Borrower all Collateral held by Bank, and shall
                execute a termination of all security agreements and security
                interests given by Borrower to Bank, upon the execution and
                delivery of mutual general releases.

                        14.3 Indemnification. Borrower shall defend, indemnify
                and hold harmless Bank and its officers, employees, and agents
                against: (a) all obligations, demands, claims, and liabilities
                claimed or asserted by any other party in connection with the
                transactions contemplated by this Agreement; and (b) all losses
                or Bank Expenses in any way suffered, incurred, or paid by Bank
                as a result of or in any way arising out of, following, or
                consequential to transactions between Bank and Borrower whether
                under this Agreement, or otherwise (including without limitation
                reasonable attorneys fees and expenses), except for losses
                caused by Bank's gross negligence or willful misconduct.

                        14.4 Time of Essence. Time is of the essence for the
                performance of all obligations set forth in this Agreement.

                        14.5 Severability of Provisions. In the event any one or
                more of the provisions contained in this Agreement is held to be
                invalid, illegal or unenforceable in any respect, then such
                provision shall be ineffective only to the extent of such
                prohibition or invalidity, and the validity, legality, and
                enforceability of the remaining provisions contained herein
                shall not in any way be affected or impaired thereby.

                        14.6 Amendments. Neither this Agreement nor any
                provisions hereof may be changed, waived, discharged or
                terminated, nor may any consent to the departure from the terms
                hereof be given, orally (even if supported by new
                consideration), but only by an instrument in writing signed by
                all parties to this Agreement. Any waiver or consent so given
                shall be effective only in the specific instance and for the
                specific purpose for which given.

                        14.7 Entire Agreement. This Agreement, together with the
                Loan Documents embodies the entire agreement and understanding
                among and between the parties hereto, and supersedes all prior
                or contemporaneous agreements and understandings between said
                parties, verbal or written, express or implied, relating to the
                subject matter hereof. No promises of any kind have been made by
                Bank or any third party to induce Borrower to execute this
                Agreement. No course of dealing, course of performance or trade
                usage, and no parol evidence of any nature, shall be used to
                supplement or modify any terms of this Agreement.

                        14.8 Waiver. No failure to exercise and no delay in
                exercising any right, power, or remedy hereunder shall impair
                any right, power, or remedy which Bank may have, nor shall any
                such delay be construed to be a waiver of any of such rights,
                powers, or remedies, or any acquiescence in any breach or
                default hereunder; nor shall any waiver by Bank of any breach or
                default by Borrower hereunder be deemed a waiver of any default
                or breach subsequently occurring. All rights and remedies
                granted to Bank hereunder shall remain in full force and effect
                notwithstanding any single or partial exercise of, or any
                discontinuance of action begun to enforce, any such right or
                remedy. The rights and remedies specified herein are cumulative
                and not exclusive of each other or of any rights or remedies
                which Bank would otherwise have. Any waiver, permit, consent or
                approval by Bank of any breach or default hereunder must be in
                writing and shall be effective only to the extent set forth in
                such writing and only as to that specific instance.
<PAGE>   26

                        14.9 Interpretation. This Agreement and all agreements
                relating to the subject matter hereof are the product of
                negotiation and preparation by and among each party and its
                respective attorneys, and shall be construed accordingly. The
                parties waive the provisions of California Civil Code
                Section 1654.

                        14.10 Survival. All covenants, representations and
                warranties made in this Agreement shall continue in full force
                and effect so long as any Obligations remain outstanding. The
                obligations of Borrower to indemnify Bank with respect to the
                expenses, damages, losses, costs and liabilities shall survive
                until all applicable statute of limitations periods with respect
                to actions that may be brought against Bank have run, provided
                that so long as the obligations set forth in the first sentence
                of this Section 14.10 have been satisfied, and Bank has no
                commitment to make any Advances or to make any other loans to
                Borrower, Bank shall release all security interests granted
                hereunder and redeliver all Collateral held by it in accordance
                with applicable law.

                        14.11 Confidentiality. In handling any confidential
                information Bank shall exercise the same degree of care that it
                exercises with respect to its own proprietary information of the
                same types to maintain the confidentiality of any non-public
                information thereby received or received pursuant to this
                Agreement except that disclosure of such information may be made
                (a) to the subsidiaries or affiliates of Bank in connection with
                their present or prospective business relations with Borrower,
                (b) to prospective transferees or purchasers of any interest in
                the Loans, provided that they have entered into a comparable
                confidentiality agreement in favor of Borrower and have
                delivered a copy to Borrower, (c) as required by law,
                regulations, rule or order, subpoena, judicial order or similar
                order, (d) as may be required in connection with the
                examination, audit or similar investigation of Bank and (e) as
                Bank may determine in connection with the enforcement of any
                remedies hereunder. Confidential information hereunder shall not
                include information that either: (i) is in the public domain or
                in the knowledge or possession of Bank when disclosed to Bank,
                or becomes part of the public domain after disclosure to Bank
                through no fault of Bank; or (ii) is disclosed to Bank by a
                third party, provided Bank does not have actual knowledge that
                such third party is prohibited from disclosing such information.

                        14.12 Counterparts. This Agreement may be signed in any
                number of counterparts, each of which shall be an original, with
                the same effect as if all signatures were upon the same
                instrument. Delivery of an executed counterpart of the signature
                page to this Agreement by telefacsimile shall be effective as
                delivery of a manually executed counterpart of this Agreement,
                and any party delivering such an executed counterpart of the
                signature page to this Agreement by telefacsimile to any other
                party shall thereafter also promptly deliver a manually executed
                counterpart of this Agreement to such other party, provided that
                the failure to deliver such manually executed counterpart shall
                not affect the validity, enforceability, or binding effect of
                this Agreement.

                IN WITNESS WHEREOF, the parties hereto have caused this Amended
and Restated Revolving Credit and Security Agreement to be executed as of the
