         WHEREAS, Subordinating Lender and Coast wish to amend the Subordination

         NOW, THEREFORE, the parties hereto agree as follows:

                                    ARTICLE I

                                   AMENDMENTS

         Section 1. AMENDMENT TO SECTION 1 OF THE SUBORDINATION AGREEMENT.
Section 1 of the Subordination Agreement is hereby amended by adding the
following definition to such section:

         ""Excess Cash Flow" means, in any fiscal period, Borrower's EBITDA, as
         such term is defined in the Senior Loan Agreement, minus cash capital
         expenditures, minus cash tax expenses, minus capitalized software
         development costs, minus all principal payments on all debt, minus all
         interest payments on all debt."

         Section 2. AMENDMENT TO SECTION 3(b) OF THE SUBORDINATION AGREEMENT.
Section 3(b) of the Subordination Agreement is hereby amended by deleting such
Section in its entirety and replacing it with the following:

         "Restricted Payments to Subordinating Lender. Except as expressly
         provided in this Agreement, MAI and Subordination Lender Agree that MAI
         shall not make any payments to Subordinating Lender in respect of the
         Junior Debt, whether on account of principal or interest, or whether by
         way of prepayment, payment on maturity or acceleration, redemption or
         purchase, until such time as the Senior Debt shall have been paid in
         full by MAI to Senior Lender. Notwithstanding the foregoing, and
         subject to the provisions of Section 3(c) below, provided that all
         payments then due and payable on the Senior Debt have been first paid
         in full,

                                        1

         MAI may make monthly payments of unpaid interest accrued under the
         Notes in an amount not to exceed Fifty-two Thousand Dollars ($52,000);
         provided, however, that Excess Cash Flow in excess of One Hundred
         Twenty-five Thousand Dollars in any given month shall be divided
         equally between Senior Lender and Subordinating Lender."

                                   ARTICLE II

                               GENERAL PROVISIONS

         Section 1. CONDITION PRECEDENT. This Amendment shall be effective and
the effectiveness of this Amendment is expressly conditioned upon (a) the
receipt by Coast of a copy of this Amendment duly executed by Subordinating
Lender and Borrower, and (b) the receipt by Coast of a copy of that certain
Amendment Number Seven To Loan And Security Agreement, of even date herewith,
duly executed by Borrower.

         Section 2. ENTIRE AGREEMENT. The Subordination Agreement, as amended
hereby, embodies the entire agreement and understanding between the parties
hereto and supersedes all prior agreements and understandings relating to the
subject matter hereof. Borrower represents, warrants and agrees that in entering
into the Subordination Agreement, and consenting to this Amendment, it has not
relied on any representation, promise, understanding or agreement, oral or
written, of, by or with, Coast or any of its agents, employees, or counsel,
except the representations, promises, understandings and agreements specifically
contained in or referred to in the Subordination Agreement, as amended hereby.

         Section 3. CONFLICTING TERMS. In the event of a conflict between the
terms and provisions of this Amendment and the terms and provisions of the
Subordination Agreement, the terms of this Amendment shall govern. In all other
respects, the Subordination Agreement, as amended and supplemented hereby, shall
remain in full force and effect.

         Section 4. MISCELLANEOUS. This Amendment shall be governed by and
construed in accordance with the laws of the State of California. This Amendment
may be executed in any number of counterparts, all of which taken together shall
constitute one agreement, and any party hereto may execute this Amendment by
signing such counterpart.

         IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
