        agreement between Seller and Purchaser (including, but not limited to
        this Agreement) Purchaser shall have the right, upon notice to Seller in
        writing, to require Seller to repurchase all unpaid Accounts under this
        and all other agreements between Seller and Purchase, and such purchase
        shall be without recourse to Purchaser. Seller agrees to so purchase
        within seven (7) days of receipt of such written notice, said unpaid
        Accounts. In such event, Seller agrees that in addition to paying
        Purchaser any reimbursable expenses and special damages incurred by
        Purchaser, Seller shall pay all sums otherwise due under this and all
        other factoring agreements; Seller will be responsible for paying within
        the aforesaid seven day period a sum equal to the total purchase price,
        described in Section VI above, to the extent such has been paid or
        incurred by Purchaser.

    13.  No provision hereof shall obligate Purchaser in any manner or to any
         degree, to Seller or to any third party whether such third party is
         with or without notice of this Agreement, to perform for Seller in
         regard to the underlying contract which gave rise to any Account.
         Seller and each guarantor do hereby covenant and agree to indemnify and
         hold Purchaser harmless for any and all performance, responsibility or
         duty owed by Seller to any Account Payor or other third party. Seller
         does covenant and agree to fully comply, in an acceptable manner, with
         the terms of any and all agreements with Account Payors to the extent
         such might affect the Accounts.

    14.  Seller shall notify the Account Payors of its obligation to make all
         payments on the Accounts to Purchaser on the "Assignment Letter"
         provided by Purchaser (Section V-C).

    15.  Each advance order included in the description of Accounts affected
         hereby, is valid; and Seller shall complete and deliver the
         goods/services associated therewith; Seller has the capability and
         intention of filling the advance orders, in a timely manner and agrees
         to so deliver and furnish invoices for same.

   16.   Seller agrees to immediately notify Purchaser of any funds received for
         any Accounts sold to Purchaser. Seller also agrees to forward such
         funds to Purchaser immediately after notifying Purchaser of the receipt
         of these funds. Until forwarded to Purchaser, Seller holds such funds
         in trust for Purchaser and Seller shall have no rights to such funds.


                                      XII
                               DEFAULT BY SELLER

A.  Any of the following acts, omissions and/or events, shall be and are hereby
defined as events of default by seller, in addition to any further events
defined elsewhere as events of default by Seller:

    1.  Breach by Seller of its agreement with any Account Payor for whom
        Purchaser owns an Account;

    2.  Breach by Seller of any obligation, covenant or warranty hereof,
        including but not limited to its repurchase obligation and/or its
        obligation to notify and remit funds to Purchaser; or

    3.  Seller's insolvency or business failure or Seller's assignment for the
        preference of certain creditors or the taking over of the Collateral or
        any part thereof by a receiver of Seller or placing the same in the
        custody of any court or the filing by or against Seller of a petition
        for bankruptcy protection.
        (See Certification of Solvency, Exhibit C.)

B.  Upon the occurrence of an event of default or warranty breach, and at any
time thereafter, Purchaser may elect, to foreclose on its security interest in
the above-described Collateral and Seller hereby expressly waives notice, demand
and presentment.  Provided that it is specifically agreed in all events, that
upon such foreclosure, Purchaser must first proceed against the Reserve Account
balance, and exhaust such, prior to any further action in regard to any other
Collateral.

C.  In the case of an event of default or warranty breach and such foreclosure,
Purchaser shall have the right to retain the balance of the purchase price held
in the Reserve Account and to set off against the Reserve Account any and all
damages suffered by Purchaser.  Purchaser shall have and may exercise any and
all rights provided by the Uniform Commercial Code of the State of California,
to the maximum extent provided by said Code (such rights to include the right to
take possession of and dispose of the Collateral).  Purchaser shall be entitled
to avail itself of all such rights and remedies as may now or hereafter exist at
law or in equity for the enforcement of the covenants, herein and the
foreclosure of the security interest created hereby and the resort to any remedy
provided hereunder or provided by the Uniform Commercial Code of California, or
by any other law of California, and nothing shall prevent the concurrent or
subsequent employment of any other appropriate remedy or remedies.

D.  Any requirement of reasonable notice to Seller of the time and place of any
sale of the Collateral, or any other intended disposition thereof to be made,
shall be met if such notice is mailed, postage prepaid, to Seller at the last
known business address of Seller, as required by law.
<PAGE>

E.  Purchaser may remedy any default, without waiving same, or may waive any
default without waiving any prior or subsequent default.

F.  The security interest herein granted shall not be affected by nor affect any
other security taken for the indebtedness hereby secured, or any part thereof,
and any extensions may be made of Purchaser's rights and this security interest
and any releases may be executed of the Collateral, or any part hereof, herein
conveyed without affecting the priority of the security interest or the validity
thereof with reference to any third person, and the holder of said rights shall
not be limited by any election of remedies if it chooses to foreclose this
security interest by suit.


                                      XIII
                                 MISCELLANEOUS

A.  This Agreement has been made and is performable in Orange County, California
and shall be governed by the laws of the State of California.

B.  Seller and each guarantor, in addition to all other obligations owed
hereunder or in such guaranty agreements, shall, jointly and severally, be
liable for the full amount of attorney's fees and other cost incurred by
Purchaser in enforcing its rights hereunder and/or taking any legal action to
settle, collect or defend the Accounts or any part thereof or security interest
therein, together with interest on unpaid amounts at the maximum rate permitted
by law.

C.  This Agreement, and the exhibits attached hereto from time to time, set
forth the complete and entire understanding between Seller and Purchaser as to
the terms hereof.  Such Agreement shall only be modified by a written instrument
signed by all parties to be bound thereby.

D.  Purchaser shall have all of the rights and remedies of a secured party as
provided by the Uniform Commercial Code of the State of California, in addition
to all other rights and remedies provided by other applicable law and all rights
and remedies provided by this agreement.  It is understood that the security
interest created herein is intended and does hereby secure all present and
future obligations of Seller to Purchaser.

E.  Failure or delay by Purchaser in exercising any right hereunder shall not
waive the later assertion of that right nor waive Seller's future performance.

F.  Purchaser shall at all times have access to inspect and review all of
Seller's accounts and financial records to protect Purchaser's position
hereunder.  Seller shall also furnish all financial data to Purchaser,
immediately upon request for such from Purchaser and from time to time; such
financial data to include but not be limited to all deposits or receipts, all
accounts receivable and invoice payments, receipts for all required tax
payments, proof of payment of all insurance, including worker's compensation
payments and proof of all current payables.

G.  All rights of Purchaser against Seller, in the event of Seller's
nonperformance or breach, shall survive the termination of this Agreement.

H.  This Agreement shall be binding on and inure to the benefit of the parties
hereto and their legal representatives, heirs, executors, administrators,
successors and assigns.

I.  Any notice to be given hereunder shall be sufficient if in writing and
personally delivered or mailed, postage prepaid, by U.S. registered or certified
mail, return receipt requested, to the parties addresses as set forth below.
Notice shall be deemed given two (2) business days following dispatch as set
forth above.

J.  Notwithstanding any term or provision hereof which expressly or impliedly
indicates otherwise, no amount payable hereunder is payable as interest, for the
use, forbearance or detention of monies.  All amounts specifically designated as
interest shall be forgiven to the extent they cannot be restructured so as to
constitute legally imposed charges.  In no event shall this Agreement be
interpreted or enforced to contract for, charge or authorize receipt of any
interest in excess of the maximum nonusurious interest rate chargeable under
applicable law in regard to which no claim or defense of usury could
successfully be asserted.  Any amount determined by a court of proper
jurisdiction as usurious interest shall be deemed a mistake and shall be
refunded to the Seller or credited to authorized amounts owed by such Seller to
Purchaser.  Provided that nothing herein above shall limit any fees, discounts
or expenses payable to Purchaser where such do not constitute interest.
