                           LOAN AND SECURITY AGREEMENT


BORROWER:   INTELLICORP, INC.
ADDRESS:    1975 EL CAMINO REAL W.
            MOUNTAIN VIEW, CALIFORNIA  94040


DATE:       APRIL 26, 1999


THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address"). The Schedule to this Agreement (the
"Schedule") shall for all purposes be deemed to be a part of this Agreement, and
the same is an integral part of this Agreement. (Definitions of certain terms
used in this Agreement are set forth in Section 8 below.)


1.      LOANS.

        1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), in amounts
determined by Silicon in its sole discretion, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing, and subject to deduction of any Reserves for accrued
interest and such other Reserves as Silicon deems proper from time to time.

        1.2 INTEREST. All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon.

        1.3 OVERADVANCES. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

        1.4 FEES. Borrower shall pay Silicon the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Silicon and are
not refundable.

        1.5 LETTERS OF CREDIT. [Not Applicable]

2.      SECURITY INTEREST.

        2.1 SECURITY INTEREST. To secure the payment and performance of all of
the Obligations when due, Borrower hereby grants to Silicon a security interest
in all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located (collectively, the "Collateral"): All Inventory,
Equipment, Receivables, and General Intangibles, including, without limitation,
all of Borrower's Deposit Accounts, and all money, and all property now or at
any time in the future in Silicon's possession (including claims and credit
balances), and all proceeds (including proceeds of any insurance policies,
proceeds of proceeds and claims against third parties), all products and all
books and records related to any of the foregoing (all of the foregoing,
together with all other property in which Silicon may now or in the future be
granted a lien or security interest, is referred to herein, collectively, as the
"Collateral").*

        *NOTWITHSTANDING THE FOREGOING, THE COLLATERAL SHALL NOT INCLUDE ANY
RIGHTS TO EXERCISE ANY PUT UNDER THE EQUITY LETTER AGREEMENT DATED MARCH 30,
1999 BETWEEN BORROWER AND CERTAIN INVESTORS, PURSUANT TO WHICH BORROWER HAS THE
RIGHT TO REQUIRE SUCH INVESTORS TO PURCHASE EQUITY SECURITIES OF THE BORROWER,

SILICON).

3.      REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

        In order to induce Silicon to enter into this Agreement and to make
Loans, Borrower represents and warrants to Silicon as follows, and Borrower
covenants that the following representations will continue to be true, and that
Borrower will at all times comply with all of the following covenants:

        3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is
and will continue to be, duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation. Borrower is and will
continue to be qualified and licensed to do business in all jurisdictions in
which any failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

        3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon * days' prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

        *10

        3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth in
the heading to this Agreement is Borrower's chief executive office. In addition,
Borrower has places of business * and Collateral is located only at the
locations set forth on the Schedule. Borrower will give Silicon at least ** days

its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule***.

          *IN THE UNITED STATES

         **10

        ***TO MAINTAIN PERFECTION OF SILICON'S SECURITY INTEREST

        3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at
all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower. The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens. Silicon now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Silicon and the Collateral against all claims
of others. None of the Collateral now is or will be affixed to any real property
in such a manner, or with such intent, as to become a fixture. Borrower is not
and will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises. Whenever any Collateral
is located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Silicon, use its * to cause such third
party to execute and deliver to Silicon, in form acceptable to Silicon, such
waivers and subordinations as Silicon shall specify, so as to ensure that
Silicon's rights in the Collateral are, and will continue to be, superior to the
rights of any such third party. Borrower will keep in full force and effect, and
will comply with all the terms of, any lease of real property where any of the
Collateral now or in the future may be located**.

         *COMMERCIALLY REASONABLE EFFORTS

        **IF A FAILURE TO SO COMPLY WOULD MATERIALLY AND ADVERSELY AFFECT THE
          COLLATERAL

        3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in
good working condition, and Borrower will not use the Collateral for any
unlawful purpose. Borrower will immediately advise Silicon in writing of any
material loss or damage to the Collateral.

        3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

        3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial
statements now or in the future delivered to Silicon have been, and will be,
prepared in conformity with generally accepted accounting principles and now and
in the future will * the financial condition of Borrower, at the times and for
the periods therein stated. Between the last date covered by any such statement
provided to Silicon and the date hereof, there has been no material adverse
change in the

filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower *, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

        *THAT COULD HAVE A MATERIAL ADVERSE EFFECT ON BORROWER

        3.9 COMPLIANCE WITH LAW. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

        3.10 LITIGATION. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of *
or more, or involving ** or more in the aggregate.

        *$100,000   **$200,000

        3.11 USE OF PROCEEDS. All proceeds of all Loans shall be used solely for
lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

        4.2 REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. Borrower

deliver to Silicon transaction reports and loan requests, schedules and

deliver the same shall not affect or limit Silicon's security interest and other
rights in all of Borrower's Receivables, nor shall Silicon's failure to advance
or lend against a specific Receivable affect or limit Silicon's security
interest and other rights therein. Loan requests received after 12:00 Noon will
not be considered by Silicon until the next Business Day. * with each such
schedule and assignment, or later if requested by Silicon, Borrower shall
furnish Silicon with copies (or, at Silicon's request, originals) of all

delivery, for any goods the sale or disposition of which gave rise to such
Receivables, and Borrower warrants the genuineness of all of the foregoing.
Borrower shall also furnish to Silicon an aged accounts receivable trial balance
in such form and at such intervals as Silicon shall request. In addition,
Borrower shall deliver to Silicon the originals of all instruments, chattel

          *AND IS CONTINUING

         **AND IF AT ANY TIME SILICON IS HOLDING FUNDS IN EXCESS OF THE
OBLIGATIONS AND NO EVENT OF DEFAULT OR EVENT WHICH, WITH NOTICE OR PASSAGE OF
TIME OR BOTH, WOULD CONSTITUTE AN EVENT OF DEFAULT UNDER THE LOAN AGREEMENT, HAS
OCCURRED AND IS CONTINUING, THEN SILICON WILL RELEASE SUCH EXCESS FUNDS TO
BORROWER.

        ***NOTWITHSTANDING THE FOREGOING, BORROWER SHALL HAVE THE RIGHT TO
MAINTAIN COMMERCIALLY REASONABLE AMOUNTS OF CASH IN FOREIGN CURRENCIES TO
SUPPORT ITS FOREIGN OPERATIONS, PROVIDED THE SAME REPRESENT THE PROCEEDS OF
FOREIGN RECEIVABLES WHICH ARE PAYABLE IN FOREIGN CURRENCIES, AND PROVIDED NO
EVENT OF DEFAULT AND NO EVENT WHICH, WITH NOTICE OR PASSAGE OF TIME OR BOTH,
WOULD CONSTITUTE AN EVENT OF DEFAULT, HAS OCCURRED AND IS CONTINUING

        4.5. REMITTANCE OF PROCEEDS. All proceeds arising from the disposition
of any Collateral shall be delivered, in kind, by Borrower to Silicon in the
original form in which received by Borrower not later than the following
Business Day after receipt by Borrower, to be applied to the Obligations in such

in good faith in an arm's length transaction for an aggregate purchase price of
$25,000 or less (for all such transactions in any fiscal year). Borrower agrees
that it will not commingle proceeds of Collateral with any of Borrower's other
funds or property, but will hold such proceeds separate and apart from such
other funds and property and in an express trust for Silicon. Nothing in this
Section limits the restrictions on disposition of Collateral set forth elsewhere
in this Agreement. *

        *NOTWITHSTANDING THE FOREGOING, BORROWER SHALL HAVE THE RIGHT TO
MAINTAIN COMMERCIALLY REASONABLE AMOUNTS OF CASH IN FOREIGN CURRENCIES TO
SUPPORT ITS FOREIGN OPERATIONS, PROVIDED THE SAME REPRESENT THE PROCEEDS OF

claims relating to Receivables. Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Silicon on the regular reports provided to Silicon; (ii) no Default
or Event of Default has occurred and is continuing; and (iii) taking into
account all such discounts settlements and forgiveness, the total outstanding
Loans will not exceed the Credit Limit. Silicon may, at any time after the
occurrence * of an Event of Default, settle or adjust disputes or claims
directly with Account Debtors for amounts and upon terms which Silicon considers
advisable in its reasonable credit judgment and, in all cases, Silicon shall
credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

        *AND DURING THE CONTINUANCE

continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason
for such return and * promptly issue a credit memorandum to the Account Debtor
in the appropriate amount (sending a copy to Silicon). In the event any
attempted return occurs after the occurrence of any Event of Default, Borrower
shall (i) hold the returned Inventory in trust for Silicon, (ii) segregate all
returned Inventory from all of Borrower's other property, (iii) conspicuously
label the returned Inventory as Silicon's property, and (iv) immediately notify
Silicon of the return of any Inventory, specifying the reason for such return,
the loca-

such returned Inventory to Silicon.

        *, IF BORROWER WISHES TO ACCEPT THE RETURN,

        4.8 VERIFICATION. Silicon may, from time to time, verify directly with
the respective Account Debtors the validity, amount and other matters relating
to the Receivables, by means of mail, telephone or otherwise, either in the name
of Borrower or Silicon or such other name as Silicon may choose.

        4.9 NO LIABILITY. Silicon shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to
a Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Silicon be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable. Nothing herein shall, however, relieve Silicon from liability for
its own gross negligence or willful misconduct.

5.      ADDITIONAL DUTIES OF THE BORROWER.

        5.1 FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply
with the financial and other covenants set forth in the Schedule.

        5.2 INSURANCE. Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies * shall name Silicon as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Silicon. Upon receipt of the proceeds of any such
insurance, Silicon shall apply such proceeds in reduction of the Obligations as
Silicon shall determine in its sole discretion, except that, provided no Default
or Event of Default has occurred and is continuing, Silicon shall release to
Borrower insurance proceeds with respect to Equipment totaling less than
$100,000, which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid. Silicon may
require reasonable assurance that the insurance proceeds so released will be so
used. If Borrower fails to provide or pay for any insurance, Silicon may, but is
not obligated to, obtain the same at Borrower's expense. Borrower shall promptly
deliver to Silicon copies of all reports made to insurance companies. **

         *(EXCEPT THOSE WITH RESPECT TO EQUIPMENT SUBJECT TO PERMITTED LIENS)

        **NOTWITHSTANDING THE FOREGOING, SILICON SHALL RELEASE ALL INSURANCE
PROCEEDS TO BORROWER IF NO LOANS ARE OUTSTANDING.

        5.3 REPORTS. Borrower, at its expense, shall provide Silicon with the
written reports set forth in the Schedule, and such other written reports with
respect to Borrower (including budgets, sales projections, operating plans and
other financial documentation), as Silicon shall from time to time reasonably
specify.

        5.4 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times, and on
one Business Day's notice, Silicon, or its agents, shall have the right to
inspect the Collateral, and the right to audit and copy Borrower's books and
records. Silicon shall take reasonable steps to keep confidential all
information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $500 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement. Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,
divulgence or delivery of any of its books and records (except that Borrower
does not waive any attorney-client privilege).

        5.5 NEGATIVE COVENANTS. Except as may be permitted in the Schedule,
Borrower shall not, without Silicon's prior written consent +, do any of the
following: (i) merge or consolidate with another corporation or entity; (ii)
acquire any assets, except in the ordinary course of business; (iii) enter into
any other transaction outside the ordinary course of business; (iv) sell or
transfer any Collateral, except for the sale of finished Inventory in the

adverse effect on Borrower or on the prospect of repayment of the Obligations;
(ix) guarantee or otherwise become liable with respect to the obligations of
another party or entity; (x) pay or declare any dividends on Borrower's stock
(except for dividends payable solely in stock of BORROWER***); (xi) redeem,

stock ****; (xii) make any change in Borrower's capital structure which would
have a material adverse effect on Borrower or on the prospect of repayment of

STOCKHOLDER FOR THE SAME PRICE AS IS CONCURRENTLY PAID BY THE STOCKHOLDER)

        +WHICH WILL BE A MATTER OF SILICON'S GOOD FAITH BUSINESS JUDGMENT

        5.6 LITIGATION COOPERATION. Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

        5.7 FURTHER ASSURANCES. Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

equal to * of the Maximum Credit Limit, provided that no termination fee shall
be charged if the credit facility hereunder is replaced with a new facility from
another division of Silicon Valley Bank. The termination fee shall be due and
payable on the effective date of termination and thereafter shall bear interest
at a rate equal to the highest rate applicable to any of the Obligations.

        *$45,000 IF TERMINATION OCCURS ON OR BEFORE THE FIRST ANNIVERSARY OF THE
DATE HEREOF AND $18,500 IF TERMINATION OCCURS AFTER THE FIRST ANNIVERSARY OF THE
DATE HEREOF

        6.3 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such Obligations are otherwise then due and payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Silicon's security interests.

        7.2 REMEDIES. Upon the occurrence * of any Event of Default, and at any
time thereafter, Silicon, at its option, and without notice or demand of any
kind (all of which are hereby expressly waived by Borrower), may do any one or
more of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by
any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of

cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any

bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for

possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (d) Require
Borrower to assemble any or all of the Collateral and make it available to
Silicon at places designated by Silicon which are reasonably convenient to
Silicon and Borrower, and to remove the Collateral to such locations as Silicon
may deem advisable; (e) Complete the processing, manufacturing or repair of any
Collateral prior to a disposition thereof and, for such purpose and for the
purpose of removal, Silicon shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge; (f) Sell, lease or otherwise dispose of any of the Collateral, in its
condition at the time Silicon obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private sales,
in lots or in bulk, for cash, exchange or other property, or on credit, and to
adjourn any such sale from time to time without notice other than oral
announcement at the time scheduled for sale. Silicon shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Silicon deems reasonable, or on Silicon's premises, or elsewhere and
the Collateral need not be located at the place of disposition. Silicon may
directly or through any affiliated company purchase or lease any Collateral at
any such public disposition, and if permissible under applicable law, at any
private disposition. Any sale or other disposition of Collateral shall not
relieve Borrower of any liability Borrower may have if any Collateral is
defective as to title or physical condition or otherwise at the time of sale;
(g) Demand payment of, and collect any Receivables and General Intangibles
comprising Collateral and, in connection therewith, Borrower irrevocably

addressed to Borrower and remove therefrom payments made with respect to any
item of the Collateral or proceeds thereof, and, in Silicon's sole discretion,
to grant extensions of time to pay, compromise claims and settle Receivables and
the like for less than face value; (h) Offset against any sums in any of
Borrower's general, special or other Deposit Accounts with Silicon; and (i)

to and become part of the Obligations, shall be due on demand, and shall bear
interest at a rate equal to the highest interest rate applicable to any of the
Obligations. Without limiting any of Silicon's rights and remedies, from and
after the occurrence * of any Event of Default, the interest rate applicable to
the Obligations shall be increased by an additional ** percent per annum.

        *AND DURING THE CONTINUANCE

        **TWO

        7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and
Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general,
non-specific terms; (iii) The sale is conducted at a place designated by
Silicon, with or without the Collateral being present; (iv) The sale commences
at any time between 8:00 a.m. and 6:00 p.m; (v) Payment of the purchase price in
cash or by cashier's check or wire transfer is required; (vi) With respect to
any sale of any of the Collateral, Silicon may (but is not obligated to) direct
any prospective purchaser to ascertain directly from Borrower any and all
information concerning the same. Silicon shall be free to employ other methods
of noticing and selling the Collateral, in its discretion, if they are
commercially reasonable.

        7.4 POWER OF ATTORNEY. Upon the occurrence * of any Event of Default,
without limiting Silicon's other rights and remedies, Borrower grants to Silicon
an irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to
Borrower, and at Borrower's expense, to do any or all of the following, in
Borrower's name or otherwise, but Silicon agrees to exercise the following
powers in a commercially reasonable manner: (a) Execute on behalf of Borrower
any documents that Silicon may, in its sole discretion, deem advisable in order
to perfect and maintain Silicon's security interest in the Collateral, or in
order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral ; (c) Execute on behalf of Borrower, any
invoices relating to any Receivable, any draft against any Account Debtor and
any notice to any Account Debtor, any proof of claim in bankruptcy, any Notice
of Lien, claim of mechanic's, materialman's or other lien, or assignment or
satisfaction of mechanic's, materialman's or other lien; (d) Take control in any
manner of any cash or non-cash items of payment or proceeds of Collateral;
endorse the name of Borrower upon any instruments, or documents, evidence of
payment or Collateral that may come into Silicon's possession; (e) Endorse all
checks and other forms of remittances received by Silicon; (f) Pay, contest or
settle any lien, charge, encumbrance, security interest and adverse claim in or
to any of the Collateral, or any

judgment based thereon, or otherwise take any action to terminate or discharge
the same; (g) Grant extensions of time to pay, compromise claims and settle
Receivables and General Intangibles for less than face value and execute all
releases and other documents in connection therewith; (h) Pay any sums required
on account of Borrower's taxes or to secure the release of any liens therefor,
or both; (i) Settle and adjust, and give releases of, any insurance claim that
relates to any of the Collateral and obtain payment therefor; (j) Instruct any
third party having custody or control of any books or records belonging to, or
relating to, Borrower to give Silicon the same rights of access and other rights
with respect thereto as Silicon has under this Agreement; and (k) Take any
action or pay any sum required of Borrower pursuant to this Agreement and any
other present or future agreements. Any and all reasonable sums paid and any and
all reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Silicon with respect to the foregoing shall be added to and become
part of the Obligations, shall be payable on demand, and shall bear interest at
a rate equal to the highest interest rate applicable to any of the Obligations.
In no event shall Silicon's rights under the foregoing power of attorney or any
of Silicon's other rights under this Agreement be deemed to indicate that
Silicon is in control of the business, management or properties of Borrower.

        *AND DURING THE CONTINUATION

        7.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of any
sale of the Collateral shall be applied by Silicon first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion.
Any surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

        7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set
forth in this Agreement, Silicon shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

personally or by reputable private delivery service or by regular first-class
mail, or certified mail return receipt requested, addressed to Silicon or
Borrower at the addresses shown in the heading to this Agreement, or at any
other address designated in writing by one party to the other party. Notices to
Silicon shall be directed to the Commercial Finance Division, to the attention
of the Division Manager or the Division Credit Manager. All notices shall be
deemed to have been given upon delivery in the case of notices personally
delivered, or at the expiration of one Business Day following delivery to the
private delivery service, or two Business Days following the deposit thereof in
the United States mail, with postage prepaid.

        9.6 SEVERABILITY. Should any provision of this Agreement be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Agreement, which shall continue in full force
and effect.

        9.7 INTEGRATION. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Silicon and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement. There are
no oral understandings, representations or agreements between the parties which
are not set forth in this Agreement or in other written agreements signed by the
parties in connection herewith.

        9.8 WAIVERS. The failure of Silicon at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Silicon shall not waive
or diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any
action taken by Silicon, unless expressly required by this Agreement.

        9.9 NO LIABILITY FOR ORDINARY NEGLIGENCE. Neither Silicon, nor any of
its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Silicon shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Borrower or any other party through the ordinary negligence of Silicon, or
any of its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Silicon, but nothing herein shall relieve
Silicon from liability for its own gross negligence or willful misconduct.

        9.10 AMENDMENT. The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Silicon.

        9.11 TIME OF ESSENCE. Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

        9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute
any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce
Silicon's security interest in, the Collateral; and otherwise represent Silicon
in any litigation relating to Borrower. In satisfying Borrower's obligation
hereunder to reimburse Silicon for attorneys fees, Borrower may, for
convenience, issue checks directly to Silicon's attorneys, Levy, Small & Lallas,
but Borrower acknowledges and agrees that Levy, Small & Lallas is representing
only Silicon and not Borrower in connection with this Agreement. If either
Silicon or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)
reasonable attorneys' fees and costs incurred in the enforcement of, execution
upon or defense of any order, decree, award or judgment. All attorneys' fees and
costs to which Silicon may be entitled pursuant to this Paragraph shall
immediately become part of Borrower's Obligations, shall be due on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.

        9.13 BENEFIT OF AGREEMENT. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Silicon; provided,
however, that Borrower may not assign or transfer any of

its rights under this Agreement without the prior written consent of Silicon,
and any prohibited assignment shall be void. No consent by Silicon to any
assignment shall release Borrower from its liability for the Obligations.

        9.14 JOINT AND SEVERAL LIABILITY. If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

        9.16 PARAGRAPH HEADINGS; CONSTRUCTION. Paragraph headings are only used
in this Agreement for convenience. Borrower and Silicon acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,
define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Silicon or Borrower under any rule
of construction or otherwise.

        9.17 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and Borrower
shall be governed by the laws of the State of California. As a material part of
the consideration to Silicon to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Silicon's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Santa Clara County;
(ii) consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or any
other method permitted by law; and (iii) waives any and all rights Borrower may
have to object to the jurisdiction of any such court, or to transfer or change
the venue of any such action or proceeding.

        9.18 MUTUAL WAIVER OF JURY TRIAL. BORROWER AND SILICON EACH HEREBY WAIVE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT
OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE
INSTRUMENT OR AGREEMENT BETWEEN SILICON AND BORROWER, OR ANY CONDUCT, ACTS OR
OMISSIONS OF SILICON OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SILICON OR BORROWER, IN
ALL OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE.

BORROWER:   INTELLICORP, INC.
ADDRESS:    1975 EL CAMINO REAL W.
            MOUNTAIN VIEW, CALIFORNIA  94040

DATE:       APRIL 26, 1999


This Schedule forms an integral part of the Loan and Security Agreement between
Silicon Valley Bank and the above-borrower of even date.

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

1.  CREDIT LIMIT
      (Section 1.1):  
                        An amount not to exceed the lesser of: (i) $3,000,000 at
                        any one time outstanding (the "Maximum Credit Limit");
                        or (ii) 80% of the amount of Borrower's Eligible
                        Receivables (as defined in Section 8 above).
================================================================================

2.  INTEREST.

            INTEREST RATE (Section 1.2):

                        time, plus 2% per annum. Interest shall be calculated on
                        the basis of a 360-day year for 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.
================================================================================

3.  FEES (Section 1.4):

            Loan Fee:   $45,000, payable concurrently herewith. (Any Commitment
                        Fee previously paid by the Borrower in connection with
                        this loan shall be credited against this Fee.) In
                        addition, at such time as the total Loans outstanding
                        reach $2,250,000, Borrower shall pay Silicon an
                        additional one-time Loan Fee of $15,000.

                                   amount of the Maximum Credit Limit and the
