================================================================================


INSURANCE REQUIREMENTS. OPTIMUMCARE CORPORATION ("Grantor") understands that
insurance coverage is required in connection with the extending of a loan or the
providing of other financial accommodations to Grantor by Lender. These
requirements are set forth in the security documents. The following minimum
insurance coverages must be provided on the following described collateral (the
"Collateral"):

COLLATERAL:    ALL INVENTORY AND EQUIPMENT.
                      TYPE.  All risks, including fire, theft and liability.
                      AMOUNT.  Full insurable value.
                      BASIS.  Replacement value.
                      ENDORSEMENTS. Lender's loss payable clause with
                      stipulation that coverage will not be cancelled or
                      diminished without a minimum of ten (10) days' prior
                      written notice to Lender.

INSURANCE COMPANY. Grantor may obtain insurances from any insurance company
Grantor may choose that is reasonably acceptable to Lender. Grantor understands
that credit may not be denied solely because insurance was not purchased through
Lender.

FAILURE TO PROVIDE INSURANCE. Grantor agrees to deliver to Lender, ten (10) days
from the date of this Agreement, evidence of the required insurance as provided
above, with an effective date of July 14, 2000, or earlier. Grantor acknowledges
and agrees that if Grantor fails to provide any required insurance or fails to
continue such insurance in force, Lender may do so at Grantor's expense as
provided in the applicable security document. The cost of any such insurance, at
the option of Lender, shall be payable on demand or shall be added to the
indebtedness as provided in the security document. GRANTOR ACKNOWLEDGES THAT IF
LENDER SO PURCHASES ANY SUCH INSURANCE, THE INSURANCE WILL PROVIDE LIMITED
PROTECTION AGAINST PHYSICAL DAMAGE TO THE COLLATERAL, UP TO THE BALANCE OF THE
LOAN; HOWEVER, GRANTOR'S EQUITY INT HE COLLATERAL MAY NOT BE INSURED. IN
ADDITION, THE INSURANCE MAY NOT PROVIDE ANY PUBLIC LIABILITY OR PROPERTY DAMAGE
INDEMNIFICATION AND MAY NOT MEET THE REQUIREMENTS OF ANY FINANCIAL
RESPONSIBILITY LAWS.

AUTHORIZATION. For purposes of insurance coverage on the Collateral, Grantor
authorizes Lender to provide to any person (including any insurance agent or
company) all information Lender deems appropriate, whether regarding the
Collateral, the loan or other financial accommodations, or both.





GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS AGREEMENT TO PROVIDE
INSURANCE AND AGREES TO ITS TERMS. THIS AGREEMENT IS DATED JULY 14, 2000.

        TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts
        collected in the ordinary course of Grantor's business, Grantor shall
        not sell, offer to sell, or otherwise transfer or dispose of the
        Collateral. While Grantor is not in default under this Agreement,
        Grantor may sell inventory, but only in the ordinary course of its
        business and only to buyers who qualify as a buyer in the ordinary
        course of business. A sale in the ordinary course of Grantor's business
        does not include a transfer in partial or total satisfaction of a debt
        or any bulk sale. Grantor shall not pledge, mortgage, encumber or
        otherwise permit the Collateral to be subject to any lien, security
        interest, encumbrance, or charge, other than security interest provided
        for in this Agreement, without the prior written consent of Lender. This
        includes security interests even if junior in right to the security
        interests granted under this Agreement. Unless waived by Lender, all
        proceeds from any disposition of the Collateral (for whatever reason)
        shall be held in trust for Lender and shall not be commingled with any
        other funds; provided however, this requirement shall not constitute
        consent by Lender to any sale or other disposition. Upon receipt,
        Grantor shall immediately deliver any such proceeds to Lender.

        TITLE. Grantor represents and warrants to Lender that it holds good and
        marketable title to the Collateral, free and clear of all liens and
        encumbrances except for the lien of this Agreement. No financing
        statement concerning any of the Collateral is on file in any public
        office other than those which reflect the security interest created by
        this Agreement or to which Lender has specifically consented. Grantor
        shall defend Lender's rights in the Collateral against the claims and
        demands of all other persons.

        COLLATERAL SCHEDULES AND LOCATIONS. As often as Lender shall require,
        and insofar as the Collateral consists of accounts and general
        intangibles, Grantor shall deliver to Lender schedules of such
        Collateral, including such information as Lender may require, including
        without limitation names and addresses of account debtors and agings of
        accounts and general intangibles. Insofar as the Collateral consists of
        inventory and equipment, Grantor shall deliver to Lender, as often as
        Lender shall require, such lists, descriptions, and designations of such
        Collateral as Lender may require to identify the nature, extent, and
        location of such Collateral. Such information shall be submitted for
        Grantor and each of its subsidiaries or related companies.

        MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all
        tangible Collateral in good condition and repair. Grantor will not
        commit or permit damage to or destruction of the Collateral or any part
        of the Collateral. Lender and its designated representatives and agents
        shall have the right at all reasonable times to examine, inspect, and
        audit the Collateral wherever located. Grantor shall immediately notify
        Lender of all cases involving the return, rejection, repossession, loss
        or damage of or to any Collateral; of any request for credit or
        adjustment or of any other dispute arising with respect to the
        Collateral; and generally of all happenings and events affecting the
        Collateral or the value or the amount of the Collateral.

        TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes,
        assessments and liens upon the Collateral, its use or operation, upon
        this Agreement, upon any promissory note or notes evidencing the
        Indebtedness, or upon any of the other Related Documents. Grantor may
        withhold any such payment or may elect to contest any lien if Grantor is
        in good faith conducting an appropriate proceeding to contest the
        obligation to pay and so long as Lender's interest in the Collateral is
        not jeopardized in Lender's sole opinion. If the Collateral is subjected
        to a lien which is not discharged within fifteen (15) days, Grantor
        shall deposit with Lender cash, a sufficient corporate surety bond or
        other security satisfactory to Lender in an amount adequate to provide
        for the discharge of the lien plus any interest, costs, attorneys' fees
        or other charges that could accrue as a result of foreclosure or sale of
        the Collateral. In any contest Grantor shall defend itself and Lender
        and shall satisfy any final adverse judgment before enforcement against
        the Collateral. Grantor shall name Lender as an additional obligee under
        any surety bond furnished in the contest proceedings.

        COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply promptly
        with all laws, ordinances, rules and regulations of all governmental
        authorities, now or hereafter in effect, applicable to the ownership,
        production, disposition, or use of the Collateral. Grantor may contest
        in good faith any such law, ordinance or regulation and withhold
        compliance during any proceeding, including appropriate appeals, so long
        as Lender's interest in the Collateral, in Lender's opinion, is not
        jeopardized.

        HAZARDOUS SUBSTANCES. Grantor represents and warrants that the
        Collateral never has been, and never will be so long as this Agreement
        remains a lien on the Collateral, used for the generation, manufacture,
        storage, transportation, treatment, disposal, release or threatened
        release of any hazardous waste or substance, as those terms are defined
        in the Comprehensive Environmental Response, Compensation, and Liability
        act of 1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the
        Superfund Amendments and Reauthorization Act of 1986, Pub. L. No. 99-499
        ("SARA") the Hazardous Materials Transportation Act, 49 U.S.C. Section
        1801, et seq., the Resource Conservation and Recovery Act, 42 U.S.C.
        Section 6901, et seq., Chapters 6.5 through 7.7 of Division 20 of the
        California Health and Safety Code, Section 25100, et seq., or other
        applicable state or Federal laws, rules, or regulations adopted pursuant
        to any of the foregoing. The terms "hazardous waste" and "hazardous
        substance" shall also include, without limitation, petroleum and
        petroleum by-products or any fraction thereof and asbestos. The
        representations and warranties contained herein are based on Grantor's
        due diligence in investigating the Collateral for hazardous wastes and
        substances. Grantor hereby (a) releases and waives any future claims
        against Lender for indemnity or contribution in the event Grantor
        becomes liable for cleanup or other costs under any such laws, and (b)
        agrees to indemnify and hold harmless Lender against any and all claims
        and

<PAGE>   6

        losses resulting from a breach of this provision of this Agreement. This
        obligation to indemnify shall survive the payment of the Indebtedness
        and the satisfaction of this Agreement.

        MAINTENANCE OF CASUALTY INSURANCE. Grantor shall procure and maintain
        all risks insurance, including without limitation fire, theft and
        liability coverage together with such other insurance as Lender may
        require with respect to the Collateral, in form, amounts, coverages and
        basis reasonably acceptable to Lender and issued by a company or
        companies reasonably acceptable to Lender. Grantor, upon request of
        Lender, will deliver to Lender from time to time the policies or
        certificates of insurance in form satisfactory to Lender, including
        stipulations that coverages will not be cancelled or diminished without
        at least ten (10) days' prior written notice to Lender and not including
        any disclaimer of the insurer's liability for failure to give such a
        notice. Each insurance policy also shall include an endorsement
        providing that coverage in favor of Lender will not be impaired in any
        way by any act, omission or default of Grantor or any other person. In
        connection with all policies covering assets in which Lender holds or is
        offered a security interest, grantor will provide Lender with such loss
        payable or other endorsements as Lender may require. If Grantor at any
        time fails to obtain or maintain any insurance as required under this
        Agreement, Lender may (but shall not be obligated to) obtain such
        insurance as Lender deems appropriate, including if it so chooses
        "single interest insurance", which will cover only Lender's interest in
        the Collateral.

        APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify Lender
        of any loss or damage to the Collateral. Lender may make proof of loss
        if Grantor fails to do so within fifteen (15) days of the casualty. All
        proceeds of any insurance on the Collateral, including accrued proceeds
        thereon, shall be held by Lender as part of the Collateral. If Lender
        consents to repair or replacement of the damaged or destroyed
        Collateral, Lender shall, upon satisfactory proof of expenditure, pay or
        reimburse Grantor from the proceeds for the reasonable cost of repair or
        restoration. If Lender does not consent to repair or replacement of the
        Collateral, Lender shall retain a sufficient amount of the proceeds to
        pay all of the Indebtedness, and shall pay the balance to Grantor. Any
        proceeds which have not been disbursed within six (6) months after their
        receipt and which Grantor has not committed to the repair or restoration
        of the Collateral shall be used to prepay the Indebtedness.

        INSURANCE RESERVES. Lender may require Grantor to maintain with Lender
        reserves for payment of insurance premiums, which reserves shall be
        created by monthly payments from Grantor of a sum estimated by Lender to
        be sufficient to produce, at least fifteen (15) days before the premium
        due date, amounts at least equal to the insurance premiums to be paid.
        If fifteen (15) days before payment is due, the reserve funds are
        insufficient, Grantor shall upon demand pay any deficiency to Lender.
        The reserve funds shall be held by Lender as a general deposit and shall
        constitute a non-interest-bearing account which Lender may satisfy by
        payment of the insurance premiums required to be paid by Grantor as they
        become due. Lender does not hold the reserve funds in trust for Grantor,
        and Lender is not the agent of Grantor for payment of the insurance
        premiums required to be paid by Grantor. The responsibility for the
        payment of premiums shall remain Grantor's sole responsibility.

        INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to
        Lender reports on each exiting policy of insurance showing such
        information as Lender may reasonably request including the following:
        (a) the name of the insurer; (b) the risks insured; (c) the amount of
        the policy; (d) the property insured; (e) the then current value on the
        basis of which insurance has been obtained and the manner of determining
        that value; and (f) the expiration date of the policy. In addition,
        Grantor shall upon request by Lender (however not more often than
        annually) have an independent appraiser satisfactory to Lender
        determine, as applicable, the cash value or replacement cost of the
        Collateral.

GRANTOR'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS. Until default and except
as otherwise provided below with respect to accounts, Grantor may have
possession of the tangible personal property and beneficial use of all the
Collateral and may use it in any lawful manner not inconsistent with this
Agreement or the Related Documents, provided that Grantor's right to possession
and beneficial use shall not apply to any Collateral where possession of the
Collateral by Lender is required by law to perfect Lender's security interest in
such Collateral. Until otherwise notified by Lender, Grantor may collect any of
the Collateral consisting of accounts. At any time and even though no Event of
Default exists, Lender may exercise its rights to collect the accounts and to
notify account debtors to make payments directly to Lender for application to
the Indebtedness. If Lender at any time has possession of any Collateral,
whether before or after an Event of Default, Lender shall be deemed to have
exercised reasonable care in the custody and preservation of the Collateral if
Lender takes such action for that purpose as Grantor shall request or as Lender,
in Lender's sole discretion, shall deem appropriate under the circumstances, but
failure to honor any request by Grantor shall not of itself be deemed to be a
failure to exercise reasonable care. Lender shall not be required to take any
steps necessary to preserve any rights in the Collateral against prior parties,
nor to protect, preserve or maintain any security interest given to secure the
Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances and other claims, at any time
levied or placed on the Collateral. Lender also may (but shall not be obligated
to) pay all costs for insuring, maintaining and preserving the Collateral. All
such expenditures incurred or paid by Lender for such purposes will then bear
interest at the rate charged under the Note from the date incurred or paid by
Lender to the date of repayment by Grantor. All such expenses shall become a
part of the indebtedness and, at Lender's option, will (a) be payable on demand,
(b) be added to the balance of the Note and be apportioned among and be payable
with any installment payments to become due during either (i) the term of any
applicable insurance policy or (ii) the remaining term of the Note, or (c) be
treated as a balloon payment which will be due and payable at the Note's
maturity. This Agreement also will secure payment of these amounts. Such right
shall be in addition to all other rights and remedies to which Lender may be
entitled upon the occurrence of an Event of Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

        DEFAULT ON INDEBTEDNESS. Failure of Grantor to make any payment when due
        on the Indebtedness.

        OTHER DEFAULTS. Failure of Grantor to comply with or to perform any
        other term, obligation, covenant or condition contained in this
        Agreement or in any of the Related Documents or in any other note,
        security agreement, lease agreement or lease schedule, loan agreement or
        other agreement, whether now existing or hereafter made, between Grantor
        and U.S. Bancorp or any direct or indirect subsidiary of U.S. Bancorp.

        DEFAULT IN FAVOR IF THIRD PARTIES. Should Borrower or any Grantor
        default under any loan, extension of credit, security agreement,
        purchase or sales agreement, or any other agreement, in favor of any
        other creditor or person that may materially affect any of Borrower's
        property or Borrower's or any Grantor's ability to repay the Loans or
        perform their respective obligations under this Agreement or any of the
        Related Documents.

        FALSE STATEMENTS. Any warranty, representation or statement made or
        furnished to Lender by or on behalf of Grantor under this Agreement, the
        Note or the Related Documents is false or misleading in any material
        respect, either now or at the time made or furnished.

        DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related
        Documents ceases to be in full force and effect (including failure of
        any collateral documents to create a valid and perfected security
        interest or lien) at any time and for any reason.

        INSOLVENCY. The dissolution or termination of Grantor's existence as a
        going business, the insolvency of Grantor, the appointment of a receiver
        for any part of Grantor's property, any assignment for the benefit of
        creditors, any type of creditor workout, or the commencement of any
        proceeding under any bankruptcy or insolvency laws by or against
        Grantor.

        CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
        forfeiture proceedings, whether by judicial proceeding, self-help,
        repossession or any other method, by any creditor of Grantor or by any
        governmental agency against the Collateral or any other collateral
        securing the Indebtedness. This includes a garnishment of any of
        Grantor's deposit accounts with Lender.

<PAGE>   7

        EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
        respect to any Guarantor of any of the Indebtedness or such Guarantor
        dies or becomes incompetent.

        INSECURITY.  Lender, in good faith, deems itself insecure.

RIGHTS AND REMEDIES ON DEFAULT. In an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the California Uniform Commercial Code. In addition and without
limitation, lender may exercise any one or more of the following rights and
remedies:

        ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness,
        including any prepayment penalty which Grantor would be required to pay,
        immediately due and payable, without notice.

        ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all
        or any portion of the Collateral and any and all certificates of title
        and other documents relating to the Collateral. Lender may require
        Grantor to assemble the Collateral and make it available to Lender at a
        place to be designated by Lender. Lender also shall have full power to
        enter upon the property of Grantor to take possession of and remove the
        Collateral. If the Collateral contains other goods not covered by this
        Agreement at the time of repossession, Grantor agrees Lender may take
        such other goods, provided that Lender makes reasonable efforts to
        return them to Grantor after repossession.

        SELL THE COLLATERAL. Lender shall have full power to sell, lease,
        transfer, or otherwise deal with the Collateral or proceeds thereof in
        its own name or that of Grantor. Lender may sell the Collateral at
        public auction or private sale. Unless the Collateral threatens to
        decline speedily in value or is of a type customarily sold on a
        recognized market, Lender will give Grantor reasonable notice of the
        time after which any private sale or any other intended disposition of
        the Collateral is to be made. The requirements of reasonable notice
        shall be met if such notice is given at least ten (10) days, or such
        lesser time as required by state law, before the time of the sale or
        disposition. All expenses relating to the disposition of the Collateral,
        including without limitation the expenses of retaking, holding insuring,
        preparing for sales and selling the Collateral, shall become a part of
        the Indebtedness secured by this Agreement and shall be payable on
        demand, with interest at the Note rate from date of expenditure until
        repaid.

        APPOINT RECEIVER. To the extent permitted by applicable law, Lender
        shall have the following rights and remedies regarding the appointment
        of a receiver: (a) Lender may have a receiver appointed as a matter of
        right, (b) the receiver may be an employee of Lender and may serve
        without bond, and (c) all fees of the receiver and his or her attorney
        shall become a part of the Indebtedness secured by this Agreement and
        shall be payable on demand, with interest at the Note rate from date of
        expenditure until repaid.

        COLLECT REVENUES, APPLY ACCOUNTS. Lender, either itself or through a
        receiver, may collect the payments, rents, income, and revenues from the
        Collateral. Lender may at any time in its discretion transfer any
        Collateral into its own name or that of its nominee and receive the
        payments, rents, income, and revenues therefrom and hold the same as
        security for the Indebtedness or apply it to payment of the Indebtedness
        in such order of preference as Lender may determine. Insofar as the
        Collateral consists of accounts, general intangibles, insurance
        policies, instruments, chattel paper, choses in action, or similar
        property, Lender may demand, collect, receipt for, settle, compromise,
        adjust, sue for, foreclose, or realize on the Collateral as Lender may
        determine, whether or not Indebtedness or Collateral is then due. For
        these purposes, Lender may, on behalf of and in the name of Grantor,
        receive, open and dispose of mail addressed to Grantor; change any
        address to which mail and payments are to be sent; and endorse notes,
        checks, drafts, money orders, documents of title, instruments and items
        pertaining to payment, shipment or storage of any Collateral. To
        facilitate collection, Lender may notify account debtors and obligors on
        any Collateral to make payments directly to Lender.

        OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the
        Collateral, Lender may obtain a judgment against Grantor for any
        deficiency remaining on the Indebtedness due to Lender after application
        of all amounts received from the exercise of the rights provided in this
        Agreement. Grantor shall be liable for a deficiency even if the
        transaction described in this subsection is a sale of accounts or
        chattel paper.

        OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and remedies
        of a secured creditor under the provisions of the Uniform Commercial
        Code, as may be amended from time to time. In addition, Lender shall
        have and may exercise any or all other rights and remedies it may have
        available at law, in equity, or otherwise.

        CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether
        evidenced by this Agreement or the Related Documents or by any other
        writing, shall be cumulative and may be exercised singularly or
        concurrently. Election by Lender to pursue any remedy shall not exclude
        pursuit of any other remedy, and an election to make expenditures or to
        take action to perform an obligation of Grantor under this Agreement,
        after Grantor's failure to perform, shall not affect Lender's right to
        declare a default and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

        AMENDMENTS. This Agreement, together with any Related Documents,
        constitutes the entire understanding and agreement of the parties as to
        the matters set forth in this Agreement. No alteration of or amendment
        to this Agreement shall be effective unless given in writing and signed
        by the party or parties sought to be charged or bound by the alteration
        or amendment.

        APPLICABLE LAW. This Agreement has been delivered to Lender and accepted
        by Lender in the State of California. If there is a lawsuit, Grantor
        agrees upon Lender's request to submit to the jurisdiction of the courts
        of Sacramento County, the State of California. Subject to the provision
        on arbitration, this Agreement shall be governed by and construed in
        accordance with the laws of the State of California.

        ARBITRATION. LENDER AND GRANTOR AGREE THAT ALL DISPUTES, CLAIMS AND
        CONTROVERSIES BETWEEN THEM, WHETHER INDIVIDUAL, JOINT, OR CLASS IN
        NATURE, ARISING FROM THIS AGREEMENT OR OTHERWISE, INCLUDING WITHOUT
        LIMITATION CONTRACT AND TORT DISPUTES, SHALL BE ARBITRATED PURSUANT TO
        THE RULES OF THE AMERICAN ARBITRATION ASSOCIATION, UPON REQUEST OF
        EITHER PARTY. No act to take or dispose of any Collateral shall
        constitute a waiver of this arbitration agreement or be prohibited by
        this arbitration agreement. This includes, without limitation, obtaining
        injunctive relief or a temporary restraining order; invoking a power of
        sale under any deed of trust or mortgage; obtaining a writ of attachment
        or imposition of a receiver; or exercising any rights relating to
        personal property, including taking or disposing of such property with
        or without judicial process pursuant to Article 9 of the Uniform
        Commercial Code. Any disputes, claims, or controversies concerning the
        lawfulness or reasonableness of any act, or exercise of any right,
        concerning any Collateral, including any claim to rescind, reform, or
        otherwise modify any agreement relating to the Collateral, shall also be
        arbitrated, provided however that no arbitrator shall have the right or
        the power to enjoin or restrain any act of any party. Lender and Grantor
        agree that in the event of an action for judicial foreclosure pursuant
        to California Code of Civil Procedure Section 726, or any similar
        provision in any other state, the commencement of such an action will
        not constitute a waiver of the right to arbitrate and the court shall
        refer to arbitration as much of such action, including counterclaims, as
        lawfully may be referred to arbitration. Judgment upon any award shall
        refer to arbitration. Judgment upon any award rendered by an arbitrator
        may be entered in any court having jurisdiction. Nothing in this
        Agreement shall preclude any party from seeking equitable relief from a
        court of competent jurisdiction. The statute of limitations, estoppel,
        waiver, laches, and similar doctrines which would otherwise be
        applicable in an action brought by a party shall be applicable in any
        arbitration proceeding, and the commencement of an arbitration
        proceeding shall be deemed the commencement of an action for these
        purposes. The Federal Arbitration Act shall apply to the construction,
        interpretation, and enforcement of this arbitration provision.

        ATTORNEY'S FEES; EXPENSES. Grantor agrees to pay upon demand all of
        Lender's costs and expenses, including attorney's fees and Lender's
        legal expenses, incurred in connection with the enforcement of this
        Agreement. Lender may pay someone else to help enforce this Agreement,
        and Grantor shall pay the costs and expenses of such enforcement. Costs
        and expenses include Lender's attorney's

<PAGE>   8

        fees and legal expenses whether or not there is a lawsuit, including
        attorneys' fees and legal expenses for bankruptcy proceedings (and
        including efforts to modify or vacate any automatic stay or injunction),
        appeals, and any anticipated post-judgment collection services. Grantor
        also shall pay all court costs and such additional fees as may be
        directed by the court.

        CAPTION HEADINGS. Caption headings in this Agreement are for convenience
        purposes only and are not to be used to interpret or define the

        required by law), and shall be effective when actually delivered or when

        party may change its address for notices under this Agreement by giving
        formal written notice to the other parties, specifying that the purpose
        of the notice is to change the party's address. To the extent permitted
        by applicable law, if there is more than one Grantor, notice to any
        Grantor will constitute notice to all Grantors. For notice purposes,
        Grantor will keep Lender informed at all times of Grantor's current
        address(es).

        POWER OF ATTORNEY. Grantor hereby appoints Lender as its true and lawful
        attorney-in-fact, irrevocably, with full power of substitution to do the
        following: (a) to demand, collect, receive, receipt for, sue and recover
        all sums of money or other property which may now or hereafter become
        due, owing or payable from the Collateral; (b) to execute, sign and
        endorse any and all claims, instruments, receipts, checks, drafts or
        warrants issued in payment for the Collateral; (c) to settle or
        compromise any and all claims arising under the Collateral, and, in the
        place and stead of Grantor, to execute and deliver its release and
        settlement for the claim; and (d) to file any claim or claims or to take
        any action or institute or take part in any proceedings, either in its
        own name or in the name of Grantor, or otherwise, which in the
        discretion of Lender may seem to be necessary or advisable. This power
        is given as security forth Indebtedness, and the authority hereby
        conferred is and shall be irrevocable and shall remain in full force and
        effect until renounced by Lender.

        PREFERENCE PAYMENTS. Any monies Lender pays because of an asserted
        preference claim in Borrower's bankruptcy will become a part of the
        Indebtedness and, at Lender's option, shall be payable by Borrower as
        provided above in the "EXPENDITURES BY LENDER" paragraph.

        SEVERABILITY. If a court of competent jurisdiction finds any provision
        of this Agreement to be invalid or unenforceable as to any person or
        circumstance, such finding shall not render that provision invalid or
        unenforceable as to any other persons or circumstances. If feasible, any
        such offending provision shall be deemed to be modified to be within the
        limits of enforceability or validity; however, if the offending
        provision cannot be so modified, it shall be stricken and all other
        provisions of this Agreement in all other respects shall remain valid
        and enforceable.

        SUCCESSOR INTERESTS. Subject to the limitations set forth above on
        transfer of the Collateral, this Agreement shall be binding upon and
        inure to the benefit of the parties, their successors and assigns.

        WAIVER. Lender shall not be deemed to have waived any rights under this
        Agreement unless such waiver is given in writing and signed by Lender.
        No delay or omission on the part of Lender in exercising any right shall
        operate as a waiver of such right or any other right. A waiver by Lender
        of a provision of this Agreement shall not prejudice or constitute a
        waiver of Lender's right otherwise to demand strict compliance with that
        provision or any other provision of this Agreement. No prior waiver by
        Lender, nor any course of dealing between Lender and Grantor, shall
        constitute a waiver of any of Lender's rights or of any of Grantor's
        obligations as to any future transactions. Whenever the consent of
        Lender is required under this Agreement, the granting of such consent by
        Lender in any instance shall not constitute continuing consent to
        subsequent instances where such consent is required and in all cases
        such consent may be granted or withheld in the sole discretion of
        Lender.

        WAIVER OF CO-OBLIGOR'S RIGHTS. If more than one person is obligated for
        the Indebtedness, Borrower irrevocably waives, disclaims and
        relinquishes all claims against such other person which Borrower has or
        would otherwise have by virtue of payment of the Indebtedness or any
        part thereof, specifically including but not limited to all rights of
        indemnity, contribution or exoneration.

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS COMMERCIAL SECURITY
AGREEMENT, AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED JULY 14,
2000.

                (c) The security interests in the Collateral shall have been
                duly authorized, created, and perfected with first lien priority
                and shall be in full force and effect.

                (d) All guaranties required by Lender for the Line of Credit
                shall have been executed by each Guarantor, delivered to

<PAGE>   12

                Lender, and be in full force and effect.

                (e) Lender, at its option and for its sole benefit, shall have
                conducted an audit of Borrower's Accounts, books, records, and
                operations, and Lender shall be satisfied as to their condition.

                (f) Borrower shall have paid to Lender all fees, costs, and
                expenses specified in this Agreement and the Related Documents
                as are then due and payable.

                (g) There shall not exist at the time of any Advance a condition
                which would constitute an Event of Default under this Agreement,
                and Borrower shall have delivered to Lender the compliance
                certificate called for in the paragraph below titled "Compliance
                Certificate."

        MAKING LOAN ADVANCES. Advances under the Line of Credit may be requested
        either orally or in writing by authorized person. Lender may, but need
        not, require that all oral requests be confirmed in writing. Each
        Advance shall be conclusively deemed to have been made at the request of
        and for the benefit of Borrower (a) when credited to any deposit account
        of Borrower maintained with Lender or (b) when advanced in accordance
        with the instructions of an authorized person. Lender, at its option,
        may set a cutoff time, after which all requests for Advances will be
        treated as having been requested on the next succeeding Business Day.

        MANDATORY LOAN REPAYMENTS. If at any time the aggregate principal amount
        of the outstanding Advances shall exceed the applicable Borrowing Base,
        Borrower, immediately upon written or oral notice from Lender, shall pay
        to Lender an amount equal to the difference between the outstanding
        principal balance of the Advances and the Borrowing Base. On the
        Expiration Date, Borrower shall pay to Lender in full the aggregate
        unpaid principal amount of all Advances then outstanding and all accrued
        unpaid interest, together with all other applicable fees, costs and
        charges, if any, not yet paid.

        LOAN ACCOUNT. Lender shall maintain on its books a record of account in
        which Lender shall make entries for each Advance and such other debits
        and credits and shall be appropriate in connection with the credit
        facility. Lender shall provide Borrower with periodic statements of
        Borrower's account, which statements shall be considered to be correct
        and conclusively binding on Borrower unless Borrower notifies Lender to
        the contrary within thirty (30) days after Borrower's receipt of any
        such statement which Borrower deems to be incorrect.

COLLATERAL. To secure payment of the Line of Credit and performance of all other
Loans, obligations and duties owed by Borrower to Lender, Borrower (and others,
if required) shall grant to Lender Security Interests in such property and
assets as Lender may require (the "Collateral"), including without limitation
Borrower's present and future Accounts and general intangibles. Lender's
Security Interests in the Collateral shall be continuing liens and shall include
the proceeds and products of the Collateral, including without limitation the
proceeds of any insurance. With respect to the Collateral, Borrower agrees and
represents and warrants to Lender:

        PERFECTION OF SECURITY INTEREST. Borrower agrees to execute such
        financing statements and to take whatever other actions are requested by
        Lender to perfect and continue Lender's Security Interests in the
        Collateral. Upon request of Lender, Borrower will deliver to Lender any
        and all part of the documents evidencing or constituting the Collateral,
        and Borrower will note Lender's interest upon any and all chattel paper
        if not delivered to Lender for possession by Lender. Contemporaneous
        with the execution of this Agreement, Borrower will execute one or more
        UCC financing statements and any similar statements as may be required
        by applicable law, and will file such financing statements and all such
        similar statements in the appropriate location or locations. Borrower
        hereby appoints Lender as its irrevocable attorney-in-fact for the
        purpose of executing any documents necessary to perfect or to continue
        any Security Interest. Lender may at any time, and without further
        authorization from Borrower, file a carbon, photograph, facsimile, or
        other reproduction of any financing statement for use as a financing
        statement. Borrower will reimburse Lender for all expenses for the
        perfection, termination, and the continuation of the perfection of
        Lender's security interest in the Collateral. Borrower promptly will
        notify Lender of any change in Borrower's name including any change to
        the assumed business names of Borrower. Borrower also promptly will
        notify Lender of any change in Borrower's Social Security Number or
        Employer Identification Number. Borrower further agrees to notify Lender
        of any change in address or location of Borrower's principal governance
        office or should Borrower merge or consolidate with any other entity.

        COLLATERAL RECORDS. Borrower does now, and at all times hereafter shall,
        keep correct and accurate records of the Collateral, all of which
        records shall be available to Lender or Lender's representative upon
        demand for inspection and copying at any reasonable time. With respect
        to the Accounts, Borrower agrees to keep and maintain such records as
        Lender may require, including without limitation information concerning
        Eligible Accounts and Account balances and aging.

        COLLATERAL SCHEDULES. Concurrently with the execution and delivery of
        this Agreement, Borrower shall execute and deliver to Lender a schedule
        of Accounts and Eligible Accounts, in form and substance satisfactory to
        the Lender. Thereafter Borrower shall execute and deliver to Lender such
        supplemental schedules of Eligible Accounts and such other matters and
        information relating to Borrower's Accounts as Lender may request.
        Supplemental schedules shall be delivered according to the following
        schedule:

        AGINGS OF ACCOUNTS RECEIVABLE. BORROWER COVENANTS AND AGREES WITH LENDER
        THAT, WHILE THIS AGREEMENT IS IN EFFECT, BORROWER SHALL DELIVER TO
        LENDER WITHIN THIRTY (30) DAYS AFTER THE END OF EACH MONTH A DETAILED
        AGING OF BORROWER'S ACCOUNTS AND CONTRACTS RECEIVABLE AS OF THE LAST DAY
        OF THAT MONTH TOGETHER WITH AN EXPLANATION OF ANY ADJUSTMENTS MADE AT
        THE END OF THAT MONTH ALL IN A FORM ACCEPTABLE TO LENDER.

        BORROWING BASE CERTIFICATE. UNLESS WAIVED IN WRITING BY LENDER, BORROWER
        AGREES TO PROVIDE LENDER WITH A BORROWER'S CERTIFICATE WITHIN THIRTY
        (30) DAYS AFTER THE END OF EACH MONTH. EACH BORROWER'S CERTIFICATE SHALL
        BE IN A FORM ACCEPTABLE TO LENDER, DULY EXECUTED BY BORROWER AND
        DETAILING THE STATUS OF THE LINE OF CREDIT AS OF THE DATE THEREON.

        REPRESENTATIONS AND WARRANTIES CONCERNING ACCOUNTS. With respect to the
        Accounts, Borrower represents and warrants to Lender: (a) Each Account
        represented by Borrower to be an Eligible Account for purposes of this
        Agreement conforms to the requirements of the definition of an Eligible
        Account; (b) All Account information listed on schedules delivered to
        Lender will be true and correct, subject to immaterial variance; and (c)
        Lender, its assigns, or agents shall have the right at any time and at
        Borrower's expense to inspect, examine, and audit Borrower's records and
        to confirm with Account Debtors the accuracy of such Accounts.

REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants to Lender, as
of the date of this Agreement, as of the date of each disbursement of Loan
proceeds, as of the date of any renewal, extension or modification of any Loan,
and at all times any Indebtedness exists:

        ORGANIZATION. Borrower is a corporation which is duly organized, validly
        existing, and in good standing under the laws of the State of Delaware
        and is validly existing and in good standing in all states in which
        Borrower is doing business. Borrower has the full power and authority to
        own its properties and to transact the businesses in which it is
        presently engaged or presently proposes to engage. Borrower also is duly
        qualified as a foreign corporation and is in good standing in all states
        in which the failure to so qualify would have a material adverse effect
        on its businesses or financial condition.

        AUTHORIZATION. The execution, delivery, and performance of this
        Agreement and all Related Documents by Borrower, to the extent to be
        executed, delivered or performed by Borrower, have been duly authorized
        by all necessary action by Borrower; do not require the consent or
        approval of any other person, regulatory authority or governmental body;
        and do not conflict with, result in a violation of, or constitute a
        default under (a) any provision of its articles of incorporation or
        organization, or bylaws, or any agreement or other instrument binding
        upon Borrower or (b) any law, governmental regulation, court decree, or
        order applicable to Borrower.

<PAGE>   13

        FINANCIAL INFORMATION. Each financial statement of Borrower supplied to
        Lender truly and completely disclosed Borrower's financial condition as
        of the date of the statement, and there has been no material adverse
        change in Borrower's financial condition subsequent to the date of the
        most recent financial statement supplied to Lender. Borrower has no
        material contingent obligations except as disclosed in such financial
        statements.

        LEGAL EFFECT. This Agreement constitutes, and any instrument or
        agreement required hereunder to be given by Borrower when delivered will
        constitute, legal, valid and binding obligations of Borrower enforceable
        against Borrower in accordance with their respective terms.

        PROPERTIES. Except for Permitted Liens, Borrower owns and has good title
        to all of Borrower's properties free and clear of all Security
        Interests, and has not executed any security documents or financing
        statements relating to such properties. All of Borrower's properties are
        titled in Borrower's legal name, and Borrower has not used, or filed a
        financing statement under, any other name for at least the last five (5)
        years.

        HAZARDOUS SUBSTANCES. The terms "hazardous waste," "hazardous
        substance," "disposal," "release," and "threatened release," as used in
        this Agreement shall have the same meanings as set forth in the
        "CERCLA", "SARA," the Hazardous Materials Transportation Act, 49 U.S.C.
        Section 1801, et seq., the Resource Conservation and Recovery Act, 42
        U.S.C. Section 6901, et seq., Chapters 6.5 through 7.7 of Division 20 of
        the California Health and Safety Code, Section 25100, et seq., or other
        applicable state or Federal laws, rules, or regulations adopted pursuant
        to any of the foregoing. Except as disclosed to and acknowledged by
        Lender in writing, Borrower represents and warrants that: (a) During the
        period of Borrower's ownership of the properties, there has been no use,
        generation, manufacture, storage, treatment, disposal, release or
        threatened release of any hazardous waste or substance by any person on,
        under, about or from any of the properties. (b) Borrower has no
        knowledge of, or reason to believe that there has been (i) any use,
        generation, manufacture, storage, treatment, disposal, release, or
        threatened release of any hazardous waste or substance on, under, about
        or from the properties by any prior owners or occupants of any of the
        properties, or (ii) any actual or threatened litigation or claims of any
        kind by any person relating to such matters. (c) Neither Borrower nor
        any tenant, contractor, agent or other authorized user of any of the
        properties shall use, generate, manufacture, store, treat, dispose of,
        or release any hazardous waste or substance on, under, about or from any
        of the properties; and any such activity shall be conducted in
        compliance with all applicable federal, state, and local laws,
        regulations, and ordinances, including without limitation those laws,
        regulations and ordinances described above. Borrower authorizes Lender
        and its agents to enter upon the properties to make such inspections and
        tests as Lender may deem appropriate to determine compliance of the
        properties with this section of the Agreement. Any inspections or tests
        made by Lender shall be at Borrower's expense and for Lender's purposes
        only and shall not be construed to create any responsibility or
        liability on the part of Lender to Borrower or to any other person. The
        representations and warranties contained herein are based on Borrower's
        due diligence in investigating the properties for hazardous waste and
        hazardous substances. Borrower hereby (a) releases and waives any future
        claims against Lender for indemnity or contribution in the event
        Borrower becomes liable for cleanup or other costs under any such laws,
        and (b) agrees to indemnify and hold harmless Lender against any and all
        claims, losses, liabilities, damages, penalties, and expenses which
        Lender may directly or indirectly sustain or suffer resulting from a
        breach of this section of the Agreement or as a consequence of any use,
        generation, manufacture, storage, disposal, release or threatened
        release of a hazardous waste or substance on the properties. The
        provisions of this section of the Agreement, including the obligation to
        indemnify, shall survive the payment of the indebtedness and the
        termination or expiration of this Agreement and shall not be affected by
        Lenders' acquisition of any interest in any of the properties, whether
        by foreclosure or otherwise.

        LITIGATION AND CLAIMS. No litigation, claim, investigation,
        administrative proceeding or similar action (including those for unpaid
        taxes) against Borrower is pending or threatened, and no other event has
        occurred which may materially adversely affect Borrower's financial
        condition or properties, other than litigation, claims or other events,
        if any, that have been disclosed to and acknowledged by Lender in
        writing.

        TAXES. To the best of Borrower's knowledge, all tax returns and reports
        of Borrower that are or were required to be filed, have been filed, and
        all taxes, assessments and other governmental charges have been paid in
        full, except those presently being or to be contested by Borrower in
        good faith in the ordinary course of business and for which adequate
        reserves have been provided.

        LIEN PRIORITY. Unless otherwise previously disclosed to Lender in
        writing, Borrower has not entered into or granted any Security
        Agreements, or permitted the filing or attachment of any Security
        Interests on or affecting any of the Collateral directly or indirectly
        securing repayment of Borrower's Loan and Note, that would be prior or
        that may in any way be superior to Lender's Security Interests and
        rights in and to such Collateral.

        BINDING EFFECT. This Agreement, the Note and all Security Agreements
        directly or indirectly securing repayment of Borrower's Loan and Note
        and all of the Related Documents are binding upon Borrower as well as
        upon Borrower's successors, representatives and assigns, and are legally
        enforceable in accordance with their respective terms.

        COMMERCIAL PURPOSES. Borrower intends to use the Loan proceeds solely
        for business or commercial related purposes.

        EMPLOYEE BENEFIT PLANS. Each employee benefit plan as to which Borrower
        may have any liability complies in all material respects with all
        applicable requirements of law and regulations, and (i) no Reportable
        Event nor Prohibited Transaction (as defined in ERISA) has occurred with
        respect to any such plan, (ii) Borrower has not withdrawn from any such
        plan or initiated steps to do so, and (iii) no steps have been taken to
        terminate any such plan, and (iv) there are not unfunded liabilities
        other than those previously disclosed to Lender in writing.

        LOCATION OF BORROWER'S OFFICES AND RECORDS. Borrower's place of business
        or Borrower's Chief executive office, if Borrower has more than on place
        of business, is located at 30011 IVY GLENN DRIVE, #219, LAGUNA NIGUEL,
        CA 92677. Unless Borrower has designated otherwise in writing this
        location is also the office or offices where Borrower keeps its records
        concerning the Collateral.

        INFORMATION. All information heretofore or contemporaneously herewith
        furnished by Borrower to Lender for the purposes of or in connection
        with this Agreement or any transaction contemplated hereby is, and all
        information hereafter furnished by or on behalf of Borrower to Lender
        will be, true and accurate in every material respect on the date as of
        which such information is dated or certified; and none of such
        information is or will be incomplete by omitting to state any material
        fact necessary to make such information not misleading.

        SURVIVAL OF REPRESENTATION AND WARRANTIES. Borrower understands and
        agrees that Lender, without independent investigation, is relying upon
        the above representations and warranties in extending Loan Advances to
        Borrower. Borrower further agrees that the foregoing representations and
        warranties shall be continuing in nature and shall remain in full force
        and effect until such time as Borrower's Indebtedness shall be paid in
        full, or until this Agreement shall be terminated in the manner provided
        above, whichever is the last to occur.

AFFIRMATIVE COVENANTS. Borrower covenants and agrees with Lender that, while
this Agreement is in effect, Borrower will:

        LITIGATION. Promptly inform Lender in writing of (a) all material
        adverse changes in Borrower's financial condition, and (b) all existing
        and all threatened litigation, claims, investigations, administrative
        proceedings or similar actions affecting Borrower or any Guarantor which
        could materially affect the financial condition of Borrower or the
        financial condition of any Guarantor.

        generally accepted accounting principles, applied on a consistent basis,

        ended, audited by a certified public accountant satisfactory to Lender,
        and, as soon as available, but in no event later than forty-five (45)
        days after the end of each fiscal quarter, Borrower's balance sheet and
        profit and loss statement for the period ended, prepared and certified
        as correct to the best knowledge and belief by Borrower's chief
        financial officer or other officer or person acceptable to Lender. All
        financial reports required to be provided under this Agreement shall be
        prepared in accordance with generally accepted accounting principles,
        applied on a consistent basis, and certified by Borrower as being true
        and correct.

        payables, inventory schedules, budgets, forecasts, tax returns, and

        ratios:

        The following provisions shall apply for purposes of determining
        compliance with the foregoing financial covenants and ratios:

        COMPLIANCE WITH ALL COVENANTS AND RATIOS, EXCEPT THE FIXED CHARGE
        COVERAGE RATIO, SHALL BE DETERMINED BY CALCULATING THE RATIOS/AMOUNTS
        AS OF THE END OF EACH QUARTER.

        COMPLIANCE WITH THE FIXED CHARGE COVERAGE RATIO WILL BE CALCULATED ON A
        ROLLING FOUR QUARTER BASIS.

        Except as provided above, all computations made to determine compliance
        with the requirements contained in this paragraph shall be made in
        accordance with generally accepted accounting principles, applied on a
        consistent basis and certified by Borrower as being true and correct.

        INSURANCE. Maintain fire and other risk insurance, public liability
        insurance, and such other insurance as Lender may require with respect
        to Borrower's properties and operations, in form, amounts, coverages,
        and with insurance companies reasonably acceptable to Lender. Borrower,
        upon request of Lender, will deliver to Lender from time to time the
        policies or certificates of insurance in form satisfactory to Lender,
        including stipulations that coverage will not be cancelled or diminished
        without at least ten (10) day's prior written notice to Lender. Each
        insurance policy also shall include an endorsement providing that
        coverage in favor of Lender will not be impaired in any way by any act,
        omission or default of Borrower or any other person. In connection with
        all policies covering assets in which Lender holds or is offered a
        security interest for the Loans, Borrower will provide Lender with such
        loss payable or other endorsements as Lender may require.

        INSURANCE REPORTS. Furnish to Lender, upon request of Lender, reports on
        each existing Insurance policy showing such information as Lender may

        name of the insurer; (b) the risks insured; (c) the amount of the
        policy; (d) the properties insured; (e) the then current property values
        on the basis of which insurance has been obtained, and the manner of
        determining those values; and (f) the expiration date of the policy. In
        addition, upon request of Lender (however not more often that annually),
        Borrower will have an independent appraiser satisfactory to Lender
        determine, as applicable, the actual cash value or replacement cost of
        any Collateral. The cost of such appraisal shall be paid by Borrower.

        OTHER AGREEMENTS. Comply with all terms and conditions of all other
        agreements, whether now or hereafter existing, between Borrower and any
        other party and notify Lender immediately in writing of any default in
        connection with any other such agreements.

        LOAN PROCEEDS. Use all Loan proceeds solely for Borrower's business
        operations, unless specifically consented to the contrary by Lender in
        writing.

        TAXES, CHARGES AND LIENS. Pay and discharge when due all of its
        indebtedness and obligations, including without limitation all
        assessments, taxes, governmental charges, levies and liens, of every
        kind and nature, imposed upon Borrower or its properties, income, or
        profits, prior to the date on which penalties would attach, and all
        lawful claims that, if unpaid, might become a lien or charge upon any of
        Borrower's properties, income, or profits. Provided however, Borrower
        will not be required to pay and discharge any such assessment, tax
        charge, levy, lien or claim so long as (a) the legality of the same
        shall be contested in good faith by appropriate proceedings, and (b)
        Borrower shall have established on its books adequate reserves with
        respect to such contested assessment, tax, charge, levy, lien, or claim
        in accordance with generally accepted accounting practices. Borrower,
        upon demand of Lender, will furnish to Lender evidence of payment of the
        assessments, taxes, charges, levies, liens and claims and will authorize
        the appropriate governmental official to deliver to Lender at any time a
        written statement of any assessments, taxes, charges, levies, liens and
        claims against Borrower's properties, income, or profits.

        PERFORMANCE. Perform and comply with all terms, conditions, and
        provisions set forth in this Agreement and in the Related Documents in a
        timely manner, and promptly notify Lender if Borrower learns of the
        occurrence of any event which constitutes an Even of Default under this
        Agreement or under any of the Related Documents.

        OPERATIONS. Maintain executive and management personnel with

        and records. If Borrower now or at any time hereafter maintains any
        records (including without limitation computer generated records and
        computer software programs for the generation of such records) in the
        possession of a third party, Borrower, upon request of Lender, shall

        respects with all environmental protection federal, state and local
        laws, statutes, regulations and ordinances; not cause or permit to

        or other communication from any governmental agency or instrumentality
        concerning any intention or unintentional action or omission on
        Borrower's part in connection with any environmental activity whether or
        not there is damage to the environment and/or other natural resources.

        ADDITIONAL ASSURANCES. Make, execute and deliver to Lender such

        the Loans and to perfect all Security Interests.

RECOVERY OF ADDITIONAL COSTS. If the imposition of or any change in any law,
rule, regulation or guideline, or the interpretation or application of any
thereof by any court or administrative or governmental authority (including any
request or policy not having the force of law) shall impose, modify or make

taxes imposed on Lender), reserve requirements, capital adequacy requirements or
other obligations which would (a) increase the cost to Lender for extending or
maintaining the credit facilities to which this Agreement relates (b) reduce the
amounts payable to Lender under this Agreement or the Related Documents, or (c)
reduce the rate of return on Lender's capital as a consequence of Lender's
obligations with respect to the credit facilities to which this Agreement
relates, then Borrower agrees to pay Lender such additional amounts as will
compensate Lender therefor, within five (5) days after Lender's written demand
for such payment, which demand shall be accompanied by an explanation of such
imposition or charge and a calculation in reasonable detail of the additional
amounts payable by Borrower, which explanation and calculations shall be
conclusive in the absence of manifest error.

NEGATIVE COVENANTS. Borrower covenants and agrees with Lender that while this
Agreement is in effect, Borrower shall not, without the prior written consent of
Lender:

        recourse any of Borrower's accounts, except to Lender.

        CONTINUITY OF OPERATIONS. (a) Engage in any business activities
        substantially different than those in which Borrower is presently
        engaged, (b) cease operations, liquidate, merge, transfer, acquire or
        consolidate with any other entity, change ownership, change its name,
        dissolve or transfer or sell Collateral out of the ordinary course of
        business, (c) pay any dividends on Borrower's stock (other than
        dividends payable in its stock), provided, however that notwithstanding
        the foregoing, but only so long as no Event of Default has occurred and
        is continuing or would result from the payment of dividends, if Borrower
        is a "Subchapter S Corporation" (as defined in the Internal Revenue Code
        of 1986, as amended), Borrower may pay cash dividends on its stock to
        its shareholders from time to time in amounts necessary to enable the
        shareholders to pay income taxes and make estimated income tax payments
        to satisfy their liabilities under federal and state law which arise
        solely from their status as Shareholders of a Subchapter S Corporation

        enterprise or entity, or (c) incur any obligation as surety or guarantor
        other than in the ordinary course of business.

CESSATION OF ADVANCES. If Lender has made any commitment to make any Loan to
Borrower, whether under this Agreement or under any other agreement, Lender
shall have no obligation to make Loan Advances or to disburse Loan proceeds if :
(a) Borrower or any Guarantor is in default under the terms of this Agreement or
any of the Related Documents or any other agreement that Borrower or any
Guarantor has with Lender; (b) Borrower or any Guarantor becomes insolvent,
files a petition in bankruptcy or similar proceedings, or is adjudged a
bankrupt; (c) there occurs a material adverse change in Borrower's financial
condition, in the financial condition of any Guarantor, or in the value of any
Collateral securing the Loan; (d) any Guarantor seeks, claims or otherwise
attempts to limit, modify or revoke such Guarantor's guaranty of the Loan or any
other loan with Lender or (e) Lender in good faith deems itself insecure, even
though no Event of Default shall have incurred.

requiring Borrower to comply with applicable laws, rules, and regulations,
Borrower agrees that it will at all times comply with applicable laws relating
to disabled access including, but not limited to, all applicable titles of the
Americans with Disabilities Act of 1990.

Line of Credit Facility with no outstanding principal balance for a minimum of
thirty (30) consecutive days during each calendar year.

RIGHT OF SETOFF. Borrower grants to Lender a contractual security interest in,
and hereby assigns, conveys, delivers, pledges, and transfers to Lender all
Borrower's right, title and interest in and to, Borrower's accounts with Lender
(whether checking, savings, or some other account), including without limitation
all accounts held jointly with someone else and all accounts Borrower may open
in the future, excluding however all IRA and Keough accounts, and all trust
accounts for which the grant of a security interest would be prohibited by law.
Borrower authorizes Lender, to the extent permitted by applicable law, to charge
or setoff all sums owing on the Indebtedness against any and all such accounts.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

        DEFAULT ON INDEBTEDNESS. Failure of Borrower to make any payment when
        due on the Loans.

        OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or to
        perform when due any other term, obligation, covenant or condition
        contained in this Agreement or in any of the Related Documents, or
        failure of Borrower to comply with or to perform any other term,
        obligation, covenant or condition contained in any other agreement
        between Lender and Borrower.

        DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor
        default under any loan, extension of credit, security agreement,
        purchase or sales agreement, or any other agreement, in favor of any
        other creditor or person that may materially affect any of Borrower's
        property or Borrower's or any Grantor's ability to repay the Loans or
        perform their respective obligations under this Agreement or any of the
        Related Documents.

        FALSE STATEMENTS. Any warranty, representation or statement made or
        furnished to Lender by or on behalf of Borrower or any Grantor under
        this Agreement or the Related Documents is false or misleading in any
        material respect at the time made or furnished, or becomes false or
        misleading at any time thereafter.

        DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related
        Documents ceases to be in full force and effect (including failure of
        any Security Agreement to create a valid and perfected Security
        Interest) at any time and for any reason.

<PAGE>   16

        INSOLVENCY. The dissolution or termination Borrower's existence as a
        going business, the insolvency of Borrower, the appointment of a
        receiver for any part of Borrower's property, any assignment for the
        benefit of creditors, any type of creditor workout, or the commencement
        of any proceeding under any bankruptcy or insolvency laws by or against
        Borrower.

        CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
        forfeiture proceedings, whether by judicial proceeding, self-help,
        repossession or any other method, by any creditor of Borrower, any
        creditor of any Grantor against any collateral securing the
        Indebtedness, or by any governmental agency. This includes a
        garnishment, attachment, or levy on or of any of Borrower's deposit
        accounts with lender.

        EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
        respect to any Guarantor of any of the Indebtedness or any Guarantor

        liability under, any Guaranty of the indebtedness.

        CHANGE IN OWNERSHIP. Any change in ownership of twenty-five percent
        (25%) or more of the common stock of Borrower.

        ADVERSE CHANGE. A material adverse change occurs in Borrower's financial
        condition, or Lender believes the prospect of payment of performance of
        the Indebtedness is impaired.

        INSECURITY. Lender, in good faith, deems itself insecure.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except where
otherwise provided in this Agreement or the Related Documents, all commitments
and obligations of Lender under this Agreement or the Related Documents or any
other agreement immediately will terminate (including any obligation to make
Loan Advances or disbursements), and, at Lender's option, all Indebtedness
immediately will become due and payable, all without notice of any kind to
Borrower, except that in the case of an Event of Default of the type described
in the "Insolvency" subsection above, such acceleration shall be automatic and
not optional. In addition, Lender shall have all the rights and remedies
provided in the Related Documents or available at law, in equity, or otherwise.
Except as may be prohibited by applicable law, all of Lender's rights and
remedies shall be cumulative and may be exercised singularly or concurrently.
Election by Lender to pursue any remedy shall not exclude pursuit of any other
remedy, and an election to make expenditures or to take action to perform an
obligation of Borrower or of any Grantor shall not affect Lender's right to
declare a default and to exercise its rights and remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

        AMENDMENTS. This Agreement, together with any Related Documents,
        constitutes the entire understanding and agreement of the parties as to
        the matters set forth in this Agreement. No alteration of or amendment
        to this Agreement shall be effective unless given in writing and signed
        by the party or parties sought to be charged or bound by the alteration
        or amendment.

        APPLICABLE LAW. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED
        BY LENDER IN THE STATE OF CALIFORNIA. IF THERE IS A LAWSUIT, BORROWER
        AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS
        OF SACRAMENTO COUNTY, THE STATE OF CALIFORNIA. SUBJECT TO THE PROVISIONS
        ON ARBITRATION, THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
        ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA.

        ARBITRATION. LENDER AND BORROWER AGREE THAT ALL DISPUTES, CLAIMS AND
        CONTROVERSIES BETWEEN THEM, WHETHER INDIVIDUAL, JOINT, OR CLASS IN
        NATURE, ARISING FROM THIS AGREEMENT OR OTHERWISE, INCLUDING WITHOUT
        LIMITATION CONTRACT AND TORT DISPUTES, SHALL BE ARBITRATED PURSUANT TO
        THE RULES OF THE AMERICAN ARBITRATION ASSOCIATION, UPON REQUEST OF
        EITHER PARTY. No act to take or dispose of any Collateral shall
        constitute a waiver of this arbitration agreement or be prohibited by
        this arbitration agreement. This includes, without limitation, obtaining
        injunctive relief or a temporary restraining order; invoking power of
        sale under any deed of trust or mortgage; obtaining a writ of attachment
        or imposition of a receiver; or exercising any rights relating to
        personal property, including taking or disposing of such property with
        or without judicial process pursuant to Article 9 of the Uniform
        Commercial Code. Any disputes, claims, or controversies concerning the
        lawfulness or reasonableness of any act, or exercise of any right,
        concerning any Collateral, including any claim to rescind, reform, or
        otherwise modify any agreement relating to the Collateral, shall also be
        arbitrated, provided however that no arbitrator shall have the right or
        the power to enjoin or restrain any act of any party. Lender and
        Borrower agree that in the event of an action for judicial foreclosure
        pursuant to California Code of Civil Procedure Section 726, or any
        similar provision in other state, the commencement of such an action
        will not constitute a waiver of the right to arbitrate and the court
        shall refer to arbitration as much of such action, including
        counterclaims, as lawfully may be referred to arbitration. Judgment upon
        any award rendered by any arbitrator may be entered in any court having
        jurisdiction. Nothing in the Agreement shall preclude any party from
        seeking equitable relief from a court of competent jurisdiction. The
        statute of limitations, estoppel, waiver, laches, and similar doctrines
        which would otherwise be applicable in an action brought by a party
        shall be applicable in any arbitration proceeding, and the commencement
        of an arbitration proceeding shall be deemed the commencement of an
        action for these purposes. The Federal Arbitration Act shall apply to
        the construction, interpretation, and enforcement of this arbitration
        provision.

        CAPTION HEADINGS. Caption headings in this Agreement are for convenience
        purposes only and are not to be used to interpret or define the
        provisions of this Agreement.

        CONSENT TO LOAN PARTICIPATION. Borrower agrees and consents to Lender's
        sale or transfer, whether now or later, of one or more participation
        interests in the Loans to one or more purchasers, whether related or
        unrelated to Lender. Lender may provide, without any limitation
        whatsoever, to any one or more purchasers, any information or knowledge
        Lender may have about Borrower or about any other matter relating to the
        Loan, and Borrower hereby waives any rights to privacy it may have with
        respect to such matters. Borrower additionally waives any and all
        notices of sale of participation interests, as well as all notices of
        any repurchase of participation interests. Borrower also agrees that the
        purchasers of any such participation interests will be considered as the
        absolute owners of such interests in the Loans and will have all the
        rights granted under the participation agreement or agreements governing
        the sale of such participation interests. Borrower further waives all
        rights of offset or counterclaim that it may have now or later against
        Lender or against any purchaser of such a participation interest and
        unconditionally agrees that either Lender or such purchaser may enforce
        Borrower's obligation under the Loans irrespective of the failure or
        insolvency of any holder of any interest in the Loans. Borrower further
        agrees that the purchaser of any such participation interests may
        enforce its interests irrespective of any personal claims or defenses
        that Borrower may have against Lender.

        COSTS AND EXPENSES. Borrower agrees to pay upon demand all of Lender's
        expenses, including without limitation attorneys' fees, incurred in
        connection with the preparation, execution, enforcement modification and
        collection of this Agreement or in connection with the Loans made
        pursuant to this Agreement. Lender may pay someone else to help collect
        the Loans and to enforce this Agreement, and Borrower will pay that
        amount. This includes, subject to any limits under applicable law,
        Lender's attorneys' fees and Lender's legal expenses, whether or not
        there is a lawsuit, including attorney's fees for bankruptcy proceedings
        (including efforts to modify or vacate any automatic stay or
        injunction), appeals, and any anticipated post-judgement collection
        services. Borrower also will pay any court costs, in addition to all
        other sums provided by law.

        NOTICES. All notices required to be given under this Agreement shall be
        given in writing, may be sent by telefacsimile (unless otherwise
        required by law), and shall be effective when actually delivered or when
        deposited with a nationally recognized overnight courier or deposited in
        the United States mail, first class, postage prepaid, addressed to the
        party to whom the notice is to be given at the address shown above. Any
        party may change its address for notices under this Agreement by giving
        formal written notice to the other parties, specifying that the purpose
        of the notice is to change the party's address. To the extent permitted
        by applicable law, if there is more than one Borrower, notice to any
        Borrower will constitute notice to all Borrowers. For notice purposes,
        Borrower will keep Lender informed at all times of Borrower's current
        address(es).

        SEVERABILITY. If a court of competent jurisdiction finds any provision
        of this Agreement to be invalid or unenforceable as to any

<PAGE>   17

        person or circumstance, such finding shall not render that provision
        invalid or unenforceable as to any other persons or circumstances. If
        feasible, any such offending provision shall be deemed to be modified to
        be within the limits of enforceability or validity; however, if the
        offending provision cannot be so modified, it shall be stricken and all
        other provisions of this Agreement in all other respects shall remain
        valid and enforceable.

        SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of
        any provisions of this Agreement makes it appropriate, including without
        limitation any representation, warranty or covenant, the word "Borrower"
        as used herein shall include all subsidiaries and affiliates of
        Borrower. Notwithstanding the foregoing however, under no circumstances
        shall this Agreement be construed to require Lender to make any Loan or
        other financial accommodation to any subsidiary or affiliate of
        Borrower.

        SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or on
        behalf of Borrower shall bind its successors and assigns and shall inure
        to the benefit of Lender, its successors and assigns. Borrower shall
        not, however, have the right to assign its rights under this Agreement
        or any interest therein, without the prior written consent of Lender.

        SURVIVAL. All warranties, representations, and covenants made by
        Borrower in this Agreement or in any certificate or other instrument
        delivered by Borrower to Lender under this Agreement shall be considered
        to have been relied upon by Lender and will survive the making o the
        Loan and delivery to Lender of the Related Documents, regardless of any
        investigation made by Lender or on Lender's behalf.

<PAGE>   18

        TIME IS OF THE ESSENCE. Time is of the essence in the performance of
        this Agreement.

        WAIVER. Lender shall not be deemed to have waived any rights under this
        Agreement unless such waiver is given in writing and signed by Lender.
        No delay or omission on the part of Lender in exercising any right shall
        operate as a waiver of such right or any other right. A waiver by Lender
        of a provision of this Agreement shall not prejudice or constitute a
        waiver of Lender's right otherwise to demand strict compliance with that
        provision or any other provision of this Agreement. No prior waiver by
        Lender, nor any course of dealing between Lender and Borrower, or
        between Lender and any Grantor, shall constitute a waiver of any
        Lender's rights or of any obligations of Borrower of any Grantor as to
        any future transactions. Whenever the consent of Lender is required
        under this Agreement, the granting of such consent by Lender in any
        instance shall not constitute continuing consent in subsequent instances
        where such consent is required, and in all cases such consent may be
        granted or withheld in the sole discretion of Lender.

BORROWER ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS LOAN AGREEMENT, AND
BORROWER AGREES TO ITS TERMS. THIS AGREEMENT IS DATED AS OF JULY 14, 2000.

================================================================================

Principal Amount:$1,500,000.00    Date of Note: July 14,2000

PROMISE TO PAY. OptimumCare Corporation ("Borrower") promises to pay to U.S.
Bank National association ("Lender"), or order in lawful money of the United
States of America, the principal amount of One Million five Hundred Thousand &
00/100 Dollars ($1,500,000) or so much as may be outstanding together with
interest on the unpaid outstanding principal balance of each advance. Interest
shall be calculated from the date of each advance until repayment of each
advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal
plus all accrued unpaid interest on June 4, 2001. In addition, Borrower will pay
regular monthly payments of accrued unpaid interest beginning August 4, 2000,
and all subsequent interest payments are due on the same day of each month after
that. The annual interest rate for this Note is computed on a 365/360 basis;
that is, by applying the ratio of the annual interest rate over a year of 360
days, multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender at
Lender's address shown above or at such other place as Lender may designate in
writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an independent index which is the Wall Street
Journal Prime Rate. This is the prime rate as published in the West Coast
edition of The Wall Street Journal "Money Rates" column (the "Index"). The Index
is not necessarily the lowest rate charged by Lender on its loans. If the Index
becomes unavailable during the term of this loan, Lender may designate a
substitute Index after notice to Borrower. Lender will tell Borrower the current
index rate upon Borrower's request. Borrower understands that Lender may make
loans based on other rates as well. The interest rate change will not occur more
often that each day. The interest rate to be applied to the unpaid principal
balance of this Note will be at a rate of 0.500 percentage points over the
Index. NOTICE: Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law.

PREPAYMENT: Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund
upon early payment (whether voluntary or as a result of default), except as
otherwise required by law.


Except for the foregoing, Borrower may pay without penalty all or a portion of
the amount owed earlier than it is due. Early payments will not, unless agreed
to by Lender in writing, relieve Borrower of Borrower's obligation to continue
to make payments of accrued unpaid interest. Rather, they will reduce the
principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due, (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due, any other term, obligation, covenant , or condition contained in this Note
or any agreement related to this Note, or in any other agreement of loan
Borrower has with Lender,(c) Borrower defaults under any loan, extension of
credit, security agreement, purchase or sales agreement, or any other agreement
in favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the related documents, (d) any
representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material respect either now or
at the time made or furnished, (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy insolvency laws, (f) Borrower is in
default under any other note, security agreement, lease agreement or lease
schedule, loan agreement or other agreement, whether now existing or hereafter
made, between Borrower and U.S. Bancorp or any direct or indirect subsidiary of
U.S. Bancorp, (g) any creditor tries to take any of Borrower's property on or in
which Lender has a lien or security interest. This includes a garnishment of any
of Borrower's accounts with Lender, (h) any guarantor dies or any of the other
events described in this default section occurs with respect to any guarantor of
this Note, (i) a material adverse change occurs in Borrower's financial
condition, or Lender believes the prospect of payment of performance of the
Indebtedness is impaired, (j) Lender in good faith deems itself insecure.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice and then Borrower will pay that amount. Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay upon
final maturity, Lender, at its option, may also, if permitted under applicable
law, increase the variable interest rate on this Note to 5.500 percentage points
over the Index. Lender may hire or pay someone else to help collect this Note if
Borrower does not pay. Borrower also will pay lender that amount. This includes,
subject to any limits under applicable law, Lender's attorney's fees and
