     This Loan Modification Agreement is entered into on the above date by
Borrower and Silicon.

       1.     BACKGROUND. Borrower entered into a Loan and Security Agreement
with Silicon in March, 1997, and a Loan Modification Agreement in March, 1998
(as amended and modified from time to time, the "Loan Agreement").
Capitalized terms used in this Loan Modification Agreement shall, unless
otherwise defined in this Agreement, have the meaning given to such terms in
the Loan Agreement.

       Silicon and Borrower are entering into this Agreement to state the
terms and conditions of certain modifications to the Loan Agreement and the
Schedule, as amended prior to the date of this Agreement.

       2.     MODIFICATIONS TO LOAN AGREEMENT AND SCHEDULE.

              2.1.    The Schedule to the Loan Agreement is hereby deleted
and replaced by the Amended and Restated Schedule to Loan and Security
Agreement attached to this Agreement.

              2.2.    Borrower acknowledges and agrees that all Obligations,
including without limitation Borrower's obligation to repay amounts advanced
by Silicon to Borrower on the terms of the Loan Agreement and Schedule as
modified by this Loan Modification Agreement, are secured by all liens and
security interests granted by Borrower to Silicon in the Loan Agreement.

       3.     CONDITIONS PRECEDENT. This Loan Modification Agreement shall
not take effect until Borrower delivers to Silicon a Certified Resolution of
Borrower and such other documents as Silicon shall reasonably require to give
effect to the terms of this Loan Modification Agreement.

       4.     NO OTHER MODIFICATIONS. Except as expressly modified by this
Loan Modification Agreement, the terms of the Loan Agreement, as amended
prior to the date of this Loan Modification Agreement, shall remain unchanged
and in full force and effect. Silicon's agreement to modify the Loan
Agreement pursuant to this Loan Modification Agreement shall not obligate
Silicon to make any future modifications to the Loan Agreement or any other
loan document. Nothing in this Loan Modification Agreement shall constitute a
satisfaction of any indebtedness of any Borrower to Silicon. It is the
intention of Silicon and Borrower to retain as liable parties all makers and
endorsers of the Loan Agreement or any other loan document. Except as provided

virtue of this Loan Modification Agreement. The terms of this paragraph shall
apply not only to this Loan Modification Agreement, but also to all subsequent

         AMENDED AND RESTATED SCHEDULE TO LOAN AND SECURITY AGREEMENT


BORROWER:          Analogy, Inc.


SECURED ACCOUNTS RECEIVABLE LINE OF CREDIT

CREDIT LIMIT:      An amount not to exceed the lesser of: (i) $5,000,000 at
                   any one time outstanding, minus the Cash Management
                   Services Sublimit; or (ii) the amount of the "Borrowing
                   Base", as defined below. For purposes of this Schedule,
                   the "Borrowing Base" shall mean the sum of 80% of the Net
                   Amount of Borrower's eligible accounts receivable. With
                   respect to Borrower's accounts, "Net Amount" means the
                   gross amount of the account, minus all applicable sales,
                   use, excise and other similar taxes and minus all
                   discounts, credits and allowances of any nature granted or
                   claimed. The amount of all letters of credit and foreign
                   exchange contracts issued by Silicon at the request of
                   Borrower shall reduce, dollar for dollar, the amount
                   otherwise available to be borrowed under the formula
                   described in this paragraph.

                   Without limiting the fact that the determination of which
                   accounts are eligible for borrowing is a matter of Silicon's
                   discretion, the following shall not be deemed eligible for
                   borrowing: accounts outstanding for more than 90 days from
                   the invoice date and accounts subject to any contingencies.
                   In addition, if more than 50% of the accounts owing from an
                   account debtor are outstanding more than 90 days from the
                   invoice date or are otherwise not eligible accounts, then all
                   accounts owing from that account debtor shall be deemed
                   ineligible for borrowing. In addition, foreign accounts
                   receivable, inter-company accounts receivable, government
                   accounts, and contra accounts shall all be ineligible.
                   Finally, any account which alone exceeds 25% of total
                   accounts receivable will be ineligible to the extent said
                   account exceeds 25% of total accounts without prior written
                   approval from Bank. Itochu has been pre-approved by Silicon
                   as an eligible debtor.

INTEREST RATE:     The interest rate applicable to this Loan shall be a rate
                   equal to the "Prime Rate" in effect from time to time, plus
                   0.50% per annum. Interest calculations shall be made on the
                   basis of a 360-day year and the actual number of days
                   elapsed. "Prime Rate" means the rate announced from time to
                   time by Silicon as its "prime rate"; it is a base rate upon
                   which other rates charged by Silicon are based, and it is
                   not necessarily the best rate available at Silicon. The
                   interest rate applicable to the Obligations shall change on
                   each date there is a change in the Prime Rate.

COMMITMENT FEE:    $2,000, which is fully earned and payable at closing of
                   this Loan Modification.

MATURITY DATE:     March 4, 1999, at which time all unpaid principal and
                   accrued but unpaid interest shall be due and payable.

Page 1 - AMENDED AND RESTATED SCHEDULE TO LOAN AND SECURITY AGREEMENT



LETTERS OF CREDIT: Subject to the terms of this Agreement, as amended from
                   time to time, Silicon shall issue or cause to be issued under
                   the Credit Limit standby and commercial letters of credit for
                   the account of Borrower in an aggregate face amount not to
                   exceed the Credit Limit. Each such standby letter of credit
                   shall have an expiry date of no later than the Maturity Date.
                   All such letters of credit shall be, in form and substance,
                   acceptable to Silicon in its sole discretion and shall be
                   subject to the terms and conditions of Silicon's form
                   application and letter of credit agreement.

CASH MANAGEMENT
SERVICES SUBLIMIT: Borrower may utilize up to an aggregate amount not to
                   exceed $75,000 for Cash Management Services provided by
                   Silicon, which services will include business credit card
                   through MBNA America Bank as defined in certain cash
                   management service agreements provided to Borrower from time
                   to time in connection herewith (a "Cash Management Service"
                   or the "Cash Management Services"). All amounts actually
                   paid by Silicon in respect of a Cash Management Service or
                   Cash Management Services shall, when paid, constitute an
                   advance under the Secured Accounts Receivable Line of Credit.

FOREIGN EXCHANGE
SUBLIMIT:          Borrower may utilize up to the Credit Limit for spot and
                   future foreign exchange contracts (the "Exchange Contracts").
                   All Exchange Contracts must provide for delivery of
                   settlement on or before the Maturity Date. The limit
                   available at any time shall be reduced by the following
                   amounts (the "Foreign Exchange Reserve") on each day (the
                   "Determination date"): (i) on all outstanding Exchange
                   Contracts on which delivery is to be effected or settlement
                   allowed more than two business days from the determination
                   Date, 20% of the gross amount of the Exchange Contracts; plus
                   (ii) on all outstanding Exchange Contracts on which delivery
                   is to be effected or settlement allowed within two business
                   days after the Determination Date, 100% of the gross amount
                   of the Exchange Contract, the Borrower may request that
                   Silicon debit the Borrower's bank account with Silicon for
                   such amount, provided Borrower has immediately available
                   funds in such amounts in its bank account.

                   Whenever Borrower desires an advance, Borrower will notify
                   Silicon by facsimile transmission or by telephone not later
                   than 11:00 a.m. California time, two business days before
                   the advance is to be made. Each such notification shall be
                   promptly confirmed by a borrowing base certificate. Silicon
                   shall be entitled to rely on any such telephone notice given
                   by any person who Silicon reasonably believes to be an
                   officer of Borrower, and Borrower shall indemnify and hold
                   Silicon harmless for any damages or loss suffered by Silicon
                   as a result of such reliance.

                   Silicon may, in its discretion, terminate the Exchange
                   Contracts at any time (a) that an Event of Default occurs or
                   (b) that there is no sufficient availability under the
                   Credit Limit and Borrower does not have available funds in
                   its bank account to satisfy the Foreign Exchange Reserve. If
                   Silicon terminates the Exchange Contracts, and without
                   limitation of the FX Indemnity Provisions (as


Page 2 - AMENDED AND RESTATED SCHEDULE TO LOAN AND SECURITY AGREEMENT



                   referred to below), Borrower agrees to reimburse Silicon for
                   any and all fees, costs and expenses relating thereto or
                   arising in connection therewith.

                   Borrower shall not permit the total gross amount of all
                   Exchange Contracts on which delivery is to be effected and
                   settlement allowed in any two business day period to be
                   more than the Credit Limit, nor shall Borrower permit the
                   total gross amount of all Exchange Contracts to which
                   Borrower is a party, outstanding at any one time, to exceed
                   the Credit Limit.

                   The Borrower shall execute all standard form applications and
                   agreements of Silicon in connection with the Exchange
                   Contracts, and without limiting any of the terms of such
                   applications and agreements the Borrower will pay all
                   standard fees and charges of Silicon in connection with the
                   Exchange Contracts.

                   Without limiting any of the other terms of this Agreement or
                   any such standard form applications and agreement of
                   Silicon, Borrower agrees to indemnify Silicon and hold it
                   harmless, from and against any and all claims, debts,
                   liabilities, demands, obligations, actions, costs and
                   expenses (including, without limitation, attorneys fees of
                   counsel of Silicon's choice), of every nature and
                   description which it may sustain or incur, based upon,
                   arising out of, or in any way relating to any of the
                   Exchange Contracts or any transactions relating thereto or
                   contemplated thereby (collectively referred to as the "FX
                   Indemnity Provisions").

                   if any, that has been subordinated to the Loans in a written

                   being conducted by independent certified public accountants
                   reasonably acceptable to Silicon, together with an
                   unqualified opinion of such accountants.
