- -----------

Additional Interest thereon.

     2.6  INTEREST RATE CALCULATION.  Basic Interest, along with charges and

excess of the highest rate permitted by applicable law from time to time in
effect.

all other sums owed under any Loan Document shall be evidenced by entries in
records maintained by Lender for such purpose.  Each payment on and any other

evidence thereof.

proposes to take with respect thereto.

          (D)  GOVERNMENT REQUIRED REPORTS; PRESS RELEASES.  Promptly after
sending, issuing, making available, or filing, copies of all statements released

capital operating company" to participate in, and influence the conduct of
management of Borrower through the exercise of "management rights," as such
terms are defined in 29 C.F.R. (S) 2510.3-101(d), and:

          (a)  Permit Lender to make available to Borrower, at no cost to

          (b)  Permit Lender to make available consulting and advisory services

                                       10

 
other matters affecting the business, financial condition and prospects of
Borrower as Lender shall reasonably deem relevant at no cost to borrower; and

          (c)  If Lender reasonably believes that financial or other
developments affecting Borrower have impaired or are likely to impair Borrower's
ability to perform its obligations under this Agreement, permit Lender
reasonable access to Borrower's management and/or Board of Directors and
opportunity to present Lender's views with respect to such developments.

     5.5  ACCOUNTING RECORDS.  Maintain adequate books, accounts and records,
and prepare all financial statements in accordance with GAAP, and in compliance
with the regulations of any governmental or regulatory authority having
jurisdiction over Borrower or Borrower's business; and permit employees or
agents of Lender at such reasonable times as Lender may request, at Borrower's
expense, to inspect Borrower's properties, and to examine, and make copies and
memoranda of Borrower's books, accounts and records.

     5.6  COMPLIANCE WITH LAWS.  Comply with all laws (including Environmental
Laws), rules, regulations applicable to, and all orders and directives of any
governmental or regulatory authority having jurisdiction over, Borrower or

party.

     5.7  TAXES AND OTHER LIABILITIES.  Pay all Borrower's obligations when

covenants contained in any addendum to this Agreement.

for joint ventures, strategic alliances, licensing and similar arrangements
customary in Borrower's industry for businesses in the development stage of

such arrangement or, without the prior written consent of Lender, require
Borrower to transfer ownership of assets to such joint venture or other entity;
prepay any subordinated debt, debt for borrowed money, or debt secured by any

                         ARTICLE 7 - EVENTS OF DEFAULT

     7.1  EVENTS OF DEFAULT.  Upon the occurrence and during the continuation
of any Default, the obligation of Lender to make any additional Loan shall be
suspended.  The occurrence of any of the following shall terminate any
obligation of Lender to make any additional Loan; and shall, at the option of
Lender (1) make all sums of Basic Interest, principal, Additional Interest and
any other amounts owing under any Loan Documents immediately due and payable
without notice of default, presentment or demand for payment, protest or notice
of nonpayment or dishonor or any other notices or demands, and (2) give Lender
the right to exercise any other right or remedy provided by contract or
applicable law:

          (a)  Borrower shall fail to make any payment of principal or interest
under this Agreement, or to pay any fees or other charges when due under any
Loan Document, and such failure continues for three (3) Business Days or more
after the same first becomes due; or an Event of Default as defined in any other
Loan Document shall have occurred and not cured within thirty (30) days.

          (b)  Any representation or warranty made, or financial statement,
certificate or other document provided, by Borrower shall prove to have been
false or misleading in any material respect when made or deemed made herein.

          (c)  Borrower shall fail to pay its debts generally as they become due
or shall commence any Insolvency Proceeding with respect to itself; an
involuntary Insolvency Proceeding shall be filed against Borrower, or a
custodian, receiver, trustee, assignee for the benefit of creditors, or other
similar official, shall be appointed to take possession, custody or control of
the properties of Borrower, and such involuntary Insolvency Proceeding, petition
or appointment is acquiesced to by Borrower or is not dismissed within sixty
(60) days; or the dissolution or termination of the business of Borrower.

          (d)  Borrower shall be in default beyond any applicable period of
grace or cure under any other agreement involving the borrowing of money, the
purchase of property, the advance of credit or any other monetary liability of
any kind to Lender or to any Person which

                                      12

 
results in the acceleration of payment of such obligation in an amount in excess
of One Hundred Thousand Dollars ($100,000).

          (e)  Any governmental or regulatory authority shall take any judicial
or administrative action, or any defined benefit pension plan maintained by
Borrower shall have any unfunded liabilities, any of which, in the reasonable
judgment of Lender, might have a Material Adverse Effect.

          (f)  Any sale, transfer or other disposition of all or a substantial
or material part of the assets of Borrower, including without limitation to any
trust or similar entity, shall occur.

          (g)  Any judgment(s) singly or in the aggregate in excess of One
Hundred Thousand Dollars ($100,000) shall be entered against Borrower which
remain unsatisfied, unvacated or unstayed pending appeal for ten (10) or more
days after entry thereof.

          (h)  Borrower shall fail to perform any of its duties or obligations
under any Loan Document not specifically referenced in this Article 7.

                        ARTICLE 8 - GENERAL PROVISIONS

     8.1  NOTICES.  Any notice given by any party under any Loan Document shall
be in writing and personally delivered, sent by overnight courier, or United
States mail, postage prepaid, or sent by facsimile, to be promptly confirmed in
writing, or other authenticated message, charges prepaid, to the other party's
or parties' addresses shown on the signature pages hereto.  Each party may
change the address or facsimile number to which notices, requests and other
communications are to be sent by giving written notice of such change to each
other party.  Notice given hand delivery shall be deemed received on the date
delivered; if sent by overnight courier, on the next business day after delivery
to the courier service; if by first class mail, on the third business day after
deposit in the U.S. Mail; and if by telecopy, on the date of transmission.

     8.2  BINDING EFFECT.  The Loan Documents shall be binding upon and inure
to the benefit of Borrower and Lender and their respective successors and
assigns; provided, however, that Borrower may not assign or transfer Borrower's
rights or obligations under any Loan Document without each Lender's prior
written consent.  Lender reserves the right to sell, assign, transfer, negotiate
or grant participations in all or any part of, or any interest in, Lender's
rights and obligations under the Loan Documents.  In connection with any of the
foregoing, Lender may disclose all documents and information which Lender now or
hereafter may have relating to the Loans, Borrower, or its business.

     8.3  NO WAIVER.  Any waiver, consent or approval by Lender of any Event of
Default or breach of any provision, condition, or covenant of any Loan Document
must be in writing and shall be effective only to the extent set forth in
writing.  No waiver of any breach or default shall be deemed a waiver of any
later breach or default of the same or any other provision of any Loan Document.
No failure or delay on the part of Lender in exercising any power, right, or
privilege under any Loan Document shall operate as a waiver thereof, and no
single or partial exercise of

                                      13

 
any such power, right, or privilege shall preclude any further exercise thereof
or the exercise of any other power, right or privilege.  Lender has the right at
its sole option to continue to accept interest and/or principal payments due
under the Loan Documents after default, and such acceptance shall not constitute
a waiver of said default or an extension of the Maturity Date unless Lender
agrees otherwise in writing.

     8.4  RIGHTS CUMULATIVE.  All rights and remedies existing under the Loan
Documents are cumulative to, and not exclusive of, any other rights or remedies
available under contract or applicable law.

     8.5  UNENFORCEABLE PROVISIONS.  Any provision of any Loan Document
executed by Borrower which is prohibited or unenforceable in any jurisdiction,
shall be so only as to such jurisdiction and only to the extent of such
prohibition or unenforceability, but all the remaining provisions of any such
Loan Document shall remain valid and enforceable.

     8.6  ACCOUNTING TERMS.  Except as otherwise provided in this Agreement,
accounting terms and financial covenants and information shall be determined and
prepared in accordance with GAAP.

     8.7  INDEMNIFICATION; EXCULPATION.  Borrower shall pay and protect, defend
and indemnify Lender and Lender's employees, officers, directors, shareholders,
affiliates, correspondents, agents and representatives (other than Lender,
collectively "Agents") against, and hold Lender and each such Agent harmless
from, all claims, actions, proceedings, liabilities, damages, losses, expenses
(including, without limitation, attorneys' fees and costs) and other amounts
incurred by Lender and each such Agent, arising from (i) the matters
contemplated by this Agreement or any other Loan Documents or (ii) any
contention that Borrower has failed to comply with any law, rule, regulation,
order or directive applicable to Borrower's business; provided, however, that
this indemnification shall not apply to any of the foregoing incurred solely as
the result of Lender's or any Agent's gross negligence or willful misconduct or
breach of this agreement.  This indemnification shall survive the payment and
satisfaction of all of Borrower's Obligations to Lender.

     8.8  REIMBURSEMENT.  Borrower shall reimburse Lender for all costs and
expenses, including without limitation reasonable attorneys' fees and
disbursements expended or incurred by Lender in any arbitration, mediation,
judicial reference, legal action or otherwise in connection with (a) the
preparation, negotiation, amendment, interpretation and enforcement of the Loan
Documents, including without limitation during any workout, attempted workout,
and/or in connection with the rendering of legal advice as to Lender's rights,
remedies and obligations under the Loan Documents, (b) collecting any sum which
becomes due Lender under any Loan Document, (c) any proceeding for declaratory
relief, any counterclaim to any proceeding, or any appeal, or (d) the
protection, preservation or enforcement of any rights of Lender.  For the
purposes of this section, attorneys' fees shall include, without limitation,
fees incurred in connection with the following:  (1) contempt proceedings; (2)
discovery; (3) any motion, proceeding or other activity of any kind in
connection with an Insolvency Proceeding; (4) garnishment, levy, and debtor and
third party examinations; and (5) postjudgment motions 

                                      14

 
and proceedings of any kind, including without limitation any activity taken to
collect or enforce any judgment. All of the foregoing costs and expenses shall
be payable upon demand by Lender, and if not paid within forty-five (45) days of
presentation of invoices shall bear interest at the highest applicable Default
Rate.

     8.9  EXECUTION IN COUNTERPARTS.  This Agreement may be executed in any
number of counterparts which, when taken together, shall constitute but one
agreement.

     8.10 ENTIRE AGREEMENT.  The Loan Documents are intended by the parties as
the final expression of their agreement and therefore contain the entire
agreement between the parties and supersede all prior understandings or
agreements concerning the subject matter hereof.  This Agreement may be amended
only in a writing signed by Borrower and Lender.

     8.11 GOVERNING LAW AND JURISDICTION.

          (a)  THIS AGREEMENT AND THE LOAN DOCUMENTS SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CALIFORNIA.

          (b)  ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA
OR OF THE UNITED STATES FOR THE NORTHERN, CENTRAL OR SOUTHERN DISTRICT OF
CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF BORROWER
AND LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-
EXCLUSIVE JURISDICTION OF THOSE COURTS.  EACH OF BORROWER AND LENDER IRREVOCABLY
WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON
THE GROUNDS OF FORUM NON CONVENIENT, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS
AGREEMENT OR ANY DOCUMENT RELATED HERETO.  BORROWER AND LENDER EACH WAIVE
PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE
BY ANY OTHER MEANS PERMITTED BY CALIFORNIA LAW.

     8.12 WAIVER OF JURY TRIAL. BORROWER AND LENDER EACH WAIVES ITS RESPECTIVE
RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING
OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS, OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY ACTION, PROCEEDING OR OTHER
LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR
ANY PARTICIPANT OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT
CLAIMS, OR OTHERWISE. BORROWER AND LENDER EACH AGREES THAT ANY SUCH CLAIM OR
CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING
THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL
BY JURY IS WAIVED BY 

                                      15

 
OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING
WHICH SEEMS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS. 

IN WITNESS WHEREOF, Borrower and Lender have executed this Agreement as of the
date set forth in the preamble.

     The undersigned ("Borrower") jointly and severally promises to pay to the
order of VENTURE LENDING & LEASING, INC., a Maryland corporation ("Lender") at
its office at 2010 North First Street, Suite 310, San Jose, California 95131, or
at such other place as Lender may designate in writing, in lawful money of the
United States of America, the principal sum of _________________ Dollars
($________), with Basic Interest thereon from the date hereof until maturity,
whether scheduled or accelerated, at a fixed rate per annum equal to the
Designated Rate, and with Additional Interest in the sum of           [15% of
                                                            -----------------

- --------------------                                                      
Designated Rate for this Note, after the Interim Period, shall be seven and one-
half percent (7.5%).

     This Note is one of the Notes referred to in, and is entitled to all the
benefits of, a Loan Agreement dated as of October 10, 1996, between Borrower and
Lender.  Each capitalized term not otherwise defined herein shall have the
meaning set forth in the Loan Agreement.  The Loan Agreement contains provisions
for the acceleration of the maturity of this Note upon the happening of certain
stated events.

     Principal of and interest on this Note shall be payable as follows:

     During the Interim Period, Basic Interest shall accrue on the outstanding
principal balance at twelve percent (12%) per annum, and shall be paid monthly,
in arrears, commencing on the Borrowing Date and continuing on the last day of
each of the five (5) months immediately following the Borrowing Date.

     Commencing on the first day of the sixth (6th) full month after the
Borrowing Date, and continuing on the first day of each consecutive month
thereafter, principal and Basic Interest shall be payable, in arrears, in forty-
one (41) equal consecutive installments of _____________ Dollars ($_______ )

     Any unpaid payments of principal or interest on this Note shall bear
interest from their respective maturities, whether scheduled or accelerated, at
a rate per annum equal to the DeRatesignated Rate plus 3%, until paid in full,
whether before or after judgment.  Borrower shall pay such interest on demand.

 
     Interest, charges and fees shall be calculated for actual days elapsed on
the basis of a 360-day year, which results in higher interest, charge or fee
payments than if a 365-day year were used. In no event shall Borrower be
obligated to pay interest, charges or fees at a rate in excess of the highest
rate permitted by applicable law from time to time in effect.

     This Note shall be governed by, and construed in accordance with, the laws
of the State of California.

                                       5

 
           (E)  Debtor shall fail to perform any of its duties or obligations
under this Agreement not specifically referenced in this Article 6 and such
failure remains uncured for ten (10) or more days after notice to Debtor;

     6.2   ACCELERATION AND REMEDIES.  Upon the occurrence of any Event of
Default Secured Party shall be entitled to, at Secured Party's option, without

available to a secured party under the Uniform Commercial Code or any other
applicable law; and (c) exercise any or all of Secured Party's rights and
remedies provided for in this Agreement and in any other Loan Document. The
obligations of Debtor under this Agreement shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of any Indebtedness
is rescinded or must otherwise be returned by Secured Party upon, on account of,
or in connection with, the insolvency, bankruptcy or reorganization of Debtor,
or otherwise, all as though such payment had not been made.

     6.3   SALE OF COLLATERAL.  After the occurrence of an Event of Default
Secured Party may sell all or any part of the Collateral, at public or private
sales, to itself, a wholesaler, retailer or investor, for cash, upon credit or

commercially reasonable.  To the extent permitted by law, Debtor hereby
specifically waives all rights of redemption and any rights of stay or appraisal
which it has or may have under any applicable law in effect from time to time.
Any such public or private sales shall be held at such times and at such
place(s) as Secured Party may determine.  In case of the sale of all or any part
of the Collateral on credit or for future delivery, the Collateral so sold may
be retained by Secured Party until the selling price is paid by the purchaser,
but Secured Party shall not incur any liability in case of the failure of such
purchaser to pay for the Collateral and, in case of any such failure, such
Collateral may be resold.  Secured Party may, instead of exercising its power of
sale, proceed to enforce its security interest in the Collateral by seeking a
judgment or decree of a court of competent jurisdiction.

     6.4   DEBTOR'S OBLIGATION UPON DEFAULT.  Upon the request of Secured Party
after the occurrence of an Event of Default Debtor will:

           (A)  Assemble and make available to Secured Party the Collateral at
such place(s) as Secured Party shall designate, segregating all Collateral so
that each item is capable of identification; and

           (B)  Permit Secured Party, by Secured Party's officers, employees,
agents and representatives, to enter any premises where any Collateral is
located, to take possession of the Collateral and to remove the Collateral or to
conduct any public or private sale of the Collateral, all without any liability
of Secured Party for rent or other compensation for the use of Debtor's
premises.

                   ARTICLE 7 - SPECIAL COLLATERAL PROVISIONS

     7.1   PERFORMANCE OF DEBTOR'S OBLIGATIONS.  Without having any obligation
to do so, Secured Party may perform or pay any obligation which Debtor has 
agreed to perform or pay

                                       6

 
obligation which Debtor has agreed to perform or pay under this Agreement,
including, without limitation, the payment or discharge of taxes or Liens levied
or placed on or threatened against the Collateral. In so performing or paying,
Secured Party shall determine the action to be taken and the amount necessary to
discharge such obligations. Debtor shall reimburse Secured Party on demand for
any amounts paid by Secured Party pursuant to this Section, which amounts shall
constitute Indebtedness secured by the Collateral and shall bear interest from
the date of demand at the rate applicable to overdue payments under the Loan
Agreement.

     7.2   POWER OF ATTORNEY.  For the purpose of protecting, preserving and
enforcing the Collateral and Secured Party's rights under this Agreement, Debtor
hereby irrevocably appoints Secured Party, with full power of substitution, as
its attorney-in-fact with full power and authority to do any act which Debtor is
obligated to do, or Secured Party has the right to do, hereunder; to exercise
such rights with respect to the Collateral as Debtor might exercise; to use such
Equipment, Fixtures or other property as Debtor might use; to enter Debtor's
premises; to give notice of Secured Party's security interest in and to collect
the Collateral and the Proceeds; and to execute and file in Debtor's name any
financing statements, amendments and continuation statements necessary or
desirable to perfect or continue the perfection of Secured Party's security
interests in the Collateral.  Debtor hereby ratifies all that Secured Party
shall lawfully do or cause to be done by virtue of this appointment.

     7.3   AUTHORIZATION FOR SECURED PARTY TO TAKE CERTAIN ACTION.  The power of
attorney created in Section 7.3 is a power coupled with an interest and shall be
irrevocable.  The powers conferred on Secured Party hereunder are solely to
protect its interests in the Collateral and shall not impose any duty upon
Secured Party to exercise such powers.  Secured Party shall be accountable only
for amounts that it actually receives as a result of the exercise of such powers
and in no event shall Secured Party or any of its directors, officers,
employees, agents or representatives be responsible to Debtor for any act or
failure to act, except for gross negligence or willful misconduct.  Secured
Party may exercise this power of attorney without notice to or assent of Debtor,
in the name of Debtor, or in Secured Party's own name, from time to time in
Secured Party's sole discretion and at Debtor's expense.  To further carry out
the terms of this Agreement, Secured Party may upon the occurrence of an Event
of Default:

           (A)  Execute any statements or documents to take possession of, and
endorse and collect and receive delivery or payment of, any checks, drafts,
notes, acceptances or other instruments and documents constituting the payment
of amounts due and to become due or any performance to be rendered with respect
to the Collateral;

           (B)  Sign and endorse any invoices, freight or express bills, bills
of lading, storage or warehouse receipts; drafts, certificates and statements
under any commercial or standby letter of credit, assignments, leases, bills of
sale, or any other documents relating to the Collateral, including without
limitation the Records;

           (C)  Use or operate Collateral or any other property of Debtor for
the purpose of preserving or liquidating Collateral;

                                       7

 
           (D)  File any claim or take any other action or proceeding in any
court of law or equity or as otherwise deemed appropriate by Secured Party for
the purpose of collecting any and all monies due or securing any performance to
be rendered with respect to the Collateral;

           (E)  Commence, prosecute or defend any suits, actions or proceedings
or as otherwise deemed appropriate by Secured Party for the purpose of
protecting or collecting the Collateral. In furtherance of this right, upon the
occurrence of an Event of Default Secured Party may apply for the appointment of
a receiver or similar official to operate Debtor's business, and, to the fullest
extent permitted by law, Debtor hereby waives any right to oppose such
appointment;

           (F)  Prepare, adjust, execute, deliver and receive payment under
insurance claims, and collect and receive payment of and endorse any instrument
in payment of loss or returned premiums or any other insurance refund or return,
and apply such amounts, at Secured Party's sole discretion, toward repayment of
the Indebtedness or replacement of the Collateral.

     7.4   APPLICATION OF PROCEEDS.  Any Proceeds and other monies or property
received by Secured Party pursuant to the terms of this Agreement or any Loan
Document may be applied by Secured Party first to the payment of expenses of
collection, including without limitation to reasonable attorneys' fees, and then
to the payment of the Indebtedness in such order of application as Secured Party
may elect.  Notwithstanding the rights given to Debtor pursuant to California
Civil Code sections 1479 and 2822 or equivalent provisions in the laws of the
state specified in the governing law clause of this document (and any amendments
or successors thereto), to designate how payments will be applied, Debtor hereby
waives such rights and Secured Party shall have the right in its sole discretion
to determine the order and method of the application of payments received from
Debtor or from the sale or disposition of the Collateral and to revise such
application prospectively or retroactively at its discretion.

     7.5   DEFICIENCY.  If the proceeds of any sale of the Collateral are
insufficient to cover all costs and expenses of such sale and the payment in
full of all Indebtedness, plus all other sums required to be expended or
distributed by Secured Party, then Debtor shall be liable for any such
deficiency.

     7.6   SECURED PARTY TRANSFER.  Upon the transfer of all or any part of the
Indebtedness, Secured Party may transfer all or any part of its interest in the
Collateral and shall be fully discharged thereafter from all liability and
responsibility with respect to such interest in the Collateral so transferred,
and the transferee shall be vested with all the rights and powers of Secured
Party hereunder with respect to such interest in the Collateral so transferred.

                        ARTICLE 8 - GENERAL PROVISIONS

     8.1   NOTICES.  Any notice given by any party under this Agreement shall be
given in the manner prescribed in the Loan Agreement.

     8.2   BINDING EFFECT.  This Agreement shall be binding upon Debtor, its
permitted successors, representatives and assigns, and shall inure to the
benefit of Secured Party and its 

                                       8

 
successors, representatives and assigns; provided however that Debtor may not
assign or transfer Debtor's obligations under this Agreement without Secured
Party's prior written consent. Secured Party reserves the right to sell, assign,
or transfer its rights and powers under this Agreement in whole or in part
without notice to Debtor. In that connection, Secured Party may disclose all
documents and information which Secured Party now or hereafter may have relating
to this Agreement, Debtor or Debtor's business.

     8.3   NO WAIVER.  Any waiver, consent or approval by Secured Party of any
Event of Default or breach of any provision, condition or covenant of this
Agreement or any Loan Document must be in writing and shall be effective only to
the extent set forth in writing.  No waiver or any breach of default shall be
deemed a waiver of any later breach or default of the same or any other
provision of this Agreement or any of the Loan Documents.  No failure or delay
on the part of Secured Party in exercising any power, right or privilege under
this Agreement or any Loan Document shall operate as a waiver thereof, and no
single or partial exercise of any such power, right or privilege shall preclude
any further exercise thereof, or the exercise of any further power, right or
privilege.

     8.4   RIGHTS CUMULATIVE.  All rights and remedies existing under this
Agreement are cumulative to, and not exclusive of, any other rights or remedies
available under contract or applicable law.

     8.5   UNENFORCEABLE PROVISIONS.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall be so only as to such
jurisdiction and only to the extent of such prohibition or unenforceability, but
all the remaining provisions of this Agreement shall remain valid and
enforceable.

     8.6   GOVERNING LAW, WAIVER OF NOTICE.  Except as may be otherwise provided
by the Uniform Commercial Code or in any addendum hereto, this Agreement shall
be governed by and construed in accordance with the laws of the State of
California.  To the fullest extent permitted by law, Debtor hereby waives
presentment, demand, protest, notice of dishonor and all other notices and
demands as well as any applicable statute of limitations.

     8.7   ENTIRE AGREEMENT.  This Agreement, together with the other Loan
Documents, is intended by Debtor and Secured Party as the final expression of
Debtor's obligations to Secured Party in connection with the Collateral and
supersedes all prior understandings or agreements concerning the subject matter
hereof.  This Agreement may be amended only by a writing signed by Debtor and
accepted by Secured Party in writing.

           This certifies that VENTURE LENDING & LEASING, INC., a Maryland
corporation, or assigns (the "Holder"), for value received, is entitled to
purchase from VeriSign, Inc., a Delaware corporation (the "Company"), 17,500
fully paid and nonassessable shares of the Company's Common Stock ("Common
Stock") at $8.00 per share (the "Stock Purchase Price") at any time or from time

"Expiration Date"), upon surrender to the Company at its principal office at
2593 Coast Avenue, Mountain View, California 94043 (or at such other location as
the Company may advise Holder in writing) of this Warrant properly endorsed with
the Form of Subscription attached hereto duly filled in and signed and upon
payment in cash or by check of the aggregate Stock Purchase Price for the number
of shares for which this Warrant is being exercised determined in accordance
with the provisions hereof.  The Stock Purchase Price and the number of shares
purchasable hereunder are subject to adjustment as provided in Section 4 of this
Warrant.

           This Warrant is subject to the following terms and conditions:

     1.    Exercise; Issuance of Certificates; Payment for Shares.
           ------------------------------------------------------ 

           (a)  Unless an election is made pursuant to clause (b) of this
Section 1, this Warrant shall be exercisable at the option of the Holder, at any
time or from time to time, on or before the Expiration Date for all or any
portion of the shares of Common Stock (but not for a fraction of a share) which
may be purchased hereunder for $8.00 per share. The Company agrees that the
shares of Common Stock purchased under this Warrant shall be and are deemed to
be issued to the holder hereof as the record owner of such shares as of the
close of business on the date on which this Warrant shall have been surrendered
and payment made for such shares. Subject to the provisions of Section 2,
certificates for the shares of Common Stock so purchased, together with any
other securities or property to which the Holder hereof is entitled upon such
exercise, shall be delivered to the Holder hereof by the Company at the
Company's expense within a reasonable time after the rights represented by this
Warrant have been so exercised. Except as provided in clause (b) of this Section
1, in case of a purchase of less than all the shares which may be purchased
under this Warrant, the Company shall cancel this Warrant and execute 

 
and deliver a new Warrant or Warrants of like tenor for the balance of the
shares purchasable under the Warrant surrendered upon such purchase to the
Holder hereof within a reasonable time. Each stock certificate so delivered
shall be in such denominations of Common Stock as may be requested by the Holder
hereof and shall be registered in the name of such Holder or such other name as
shall be designated by such Holder, subject to the limitations contained in
Section 2.

           (b)  The Holder, in lieu of exercising this Warrant by the payment of
the Stock Purchase Price pursuant to clause (a) of this Section 1, may elect, at
any time on or before the Expiration Date, to receive that number of shares of
Common Stock equal to the quotient of:  (i) the difference between (A) the Per
Share Price (as hereinafter defined) of the Common Stock, less (B) the Stock
Purchase Price then in effect, multiplied by the number of shares of Common
Stock the Holder would otherwise have been entitled to purchase hereunder
pursuant to clause (a) of this Section 1 (or such lesser number of shares as the
Holder may designate in the case of a partial exercise of this Warrant); over
(ii) the Per Share Price.

           (c)  For purposes of clause (b) of this Section 1, "Per Share Price"
means the product of:  (i) the greater of (A) the average of the closing bid and
asked prices of the Company's Common Stock as quoted by NASDAQ or listed on any
exchange, whichever is applicable, as published in the Western Edition of The
                                                                          ---

- -------------------                                                       
Holder's election hereunder or, (B) if applicable at the time of or in
connection with the exercise under clause (b) of this Section 1, the gross sales
price of one share of the Company's Common Stock pursuant to a registered public
offering or that amount which shareholders of the Company will receive for each
share of Common Stock pursuant to a merger, reorganization or sale of assets;
and (ii) that number of shares of Common Stock into which each share of Common
Stock is convertible.  If the Company's Common Stock is not quoted by NASDAQ or
listed on an exchange, the Per Share Price of the Common Stock (or the
equivalent number of shares of Common Stock into which such Common Stock is
convertible) shall be the price per share which the Company would obtain from a
willing buyer for shares sold by the Company from authorized but unissued shares
as such price shall be agreed upon by the Holder and the Company or, if
agreement cannot be reached within ten (10) business days of the Holder's
election hereunder, as such price shall be determined by a panel of three (3)
appraisers, one (1) to be chosen by the Company, one (1) to be chosen by the
Holder and the third to be chosen by the first two (2) appraisers.  If the
appraisers cannot reach agreement within 30 days of the Holder's election
hereunder, then each appraiser shall deliver its appraisal and the appraisal
which is neither the highest nor the lowest shall constitute the Per Share
Price.  In the event either party fails to choose an appraiser within 30 days of
the Holder's election hereunder, then the appraisal of the sole appraiser shall
constitute the Per Share Price.  Each party shall bear the cost of the appraiser
selected by such party and the cost of the third appraiser shall be borne one-
half by each party.  In the event either party fails to choose an appraiser, the
cost of the sole appraiser shall be borne one-half by each party.

     2.    Limitation on Transfer.
           ---------------------- 

           (a)  The Warrant and the Common Stock shall not be transferable
except upon the conditions specified in this Section 2, which conditions are
intended to insure compliance 

                                       2

 
with the provisions of the Securities Act. Each holder of this Warrant or the
Common Stock issuable hereunder will cause any proposed transferee of the
Warrant or Common Stock to agree to take and hold such securities subject to the
provisions and upon the conditions specified in this Section 2.

          (b)  Each certificate representing (i) this Warrant, (ii) the Common
Stock, (iii) shares of the Company's Common Stock issued upon conversion of the
Common Stock and (iv) any other securities issued in respect of the Common Stock
or Common Stock issued upon conversion of the Common Stock upon any stock split,
stock dividend, recapitalization, merger, consolidation or similar event, shall
(unless otherwise permitted by the provisions of this Section 2 or unless such
securities have been registered under the Securities Act or sold under Rule 144)
be stamped or otherwise imprinted with a legend substantially in the following
form (in addition to any legend required under applicable state securities
laws):

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
     FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933 OR ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT
     BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
     EXEMPTION THEREFROM UNDER SAID ACT AND ANY APPLICABLE STATE
     SECURITIES LAWS.

          (c)  The Holder of this Warrant and each person to whom this Warrant
is subsequently transferred represents and warrants to the Company (by
acceptance of such transfer) that it will not transfer the Warrant (or
securities issuable upon exercise hereof unless a registration statement under
the Securities Act was in effect with respect to such securities at the time of
issuance thereof) except pursuant to (i) an effective registration statement
under the Securities Act, (ii) Rule 144 under the Securities Act (or any other
rule under the Securities Act relating to the disposition of securities), or
(iii) an opinion of counsel, reasonably satisfactory to counsel for the Company,
that an exemption from such registration is available.

     3.   Shares to be Fully Paid; Reservation of Shares.  The Company covenants
          ----------------------------------------------                        
and agrees that all shares of Common Stock which may be issued upon the exercise
of the rights represented by this Warrant will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable and free from all
preemptive rights of any shareholder and free of all taxes, liens and charges
with respect to the issue thereof.  The Company further covenants and agrees
that during the period within which the rights represented by this Warrant may
be exercised, the Company will at all times have authorized and reserved, for
the purpose of issue or transfer upon exercise of the subscription rights
evidenced by this Warrant, a sufficient number of shares of authorized but
unissued Common Stock, or other securities and property, when and as required to
provide for the exercise of the rights represented by this Warrant.  The Company
will take all such action as may be necessary to assure that such shares of
Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange upon which the Common Stock may be listed.  The Company will not take
any action which would result in any adjustment of the Stock Purchase Price (as
defined in Section 4 hereof) (i) if the total number of shares of Common Stock
issuable after 

                                       3

 
such action upon exercise of all outstanding warrants, together with all shares
of Common Stock then outstanding and all shares of Common Stock then issuable
upon exercise of all options and upon the conversion of all convertible
securities then outstanding, would exceed the total number of shares of Common
Stock then authorized by the Company's Articles of Incorporation, or (ii) if the
total number of shares of Common Stock issuable after such action upon the
conversion of all such shares of Common Stock together with all shares of Common
Stock then outstanding and then issuable upon exercise of all options and upon
the conversion of all convertible securities then outstanding would exceed the
total number of shares of Common Stock then authorized by the Company's Articles
of Incorporation.

     4.   Adjustment of Stock Purchase Price Number of Shares.  The Stock
          ---------------------------------------------------            
Purchase Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 4.  Upon each adjustment of the Stock
Purchase Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Stock Purchase Price resulting from such adjustment, the number
of shares obtained by multiplying the Stock Purchase Price in effect immediately
prior to such adjustment by the number of shares purchasable pursuant hereto
immediately prior to such adjustment, and dividing the product thereof by the
Stock Purchase Price resulting from such adjustment.

          4.1  Subdivision or Combination of Stock.  In case the Company shall
               -----------------------------------                            
at any time subdivide its outstanding shares of Common Stock into a greater
number of shares, the Stock Purchase Price in effect immediately prior to such
subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Common Stock of the Company shall be combined into a
smaller number of shares, the Stock Purchase Price in effect immediately prior
to such combination shall be proportionately increased.

          4.2  Dividends in Common Stock Other Stock, Property,
               ------------------------------------------------
Reclassification.  If at any time or from time to time the holders of Common
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor,

               (a)  Common Stock, or any shares of stock or other securities
whether or not such securities are at any time directly or indirectly
convertible into or exchangeable for Common Stock, or any rights or options to
subscribe for, purchase or otherwise acquire any of the foregoing by way of
dividend or other distribution, or

               (b)  any cash paid or payable otherwise than as a cash dividend,
or

               (c)  Common Stock or other or additional stock or other
securities or property (including cash) by way of spinoff, split-up,
reclassification, combination of shares or similar corporate rearrangement,
(other than shares of Common Stock issued as a stock split, adjustments in
respect of which shall be covered by the terms of Section 4.1 above), then and
in each such case, the Holder hereof shall, upon the exercise of this Warrant,
be entitled to receive, in addition to the number of shares of Common Stock
receivable thereupon, and without payment of any additional consideration
therefore, the amount of stock and other securities and

                                       4

 
property (including cash in the cases referred to in clauses (b) and (c) above)
which such Holder would hold on the date of such exercise had he been the holder
of record of such Common Stock as of the date on which holders of Common Stock
received or became entitled to receive such shares and/or all other additional
stock and other securities and property.

          4.3  Reorganization, Reclassification, Consolidation, Merger or Sale.
               ---------------------------------------------------------------  
If any capital reorganization of the capital stock of the Company, or any
consolidation or merger of the Company with another corporation, or the sale of
all or substantially all of its assets to another corporation shall be effected
in such a way that holders of Common Stock shall be entitled to receive stock,
securities or assets with respect to or in exchange for Common Stock, then, as a
condition of such reorganization, reclassification, consolidation, merger or
sale, lawful and adequate provisions shall be made whereby the holder hereof
shall thereafter have the right to purchase and receive(in lieu of the shares of
the Common Stock of the Company immediately theretofore purchasable and
receivable upon the exercise of the rights represented hereby) such shares of
stock, securities or assets as may be issued or payable with respect to or in
exchange for a number of outstanding shares of such Common Stock equal to the
number of shares of such stock immediately theretofore purchasable and
receivable upon the exercise of the rights represented hereby.  In any such
case, appropriate provision shall be made with respect to the rights and
interests of the holder of this Warrant to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the Stock Purchase
Price and of the number of shares purchasable and receivable upon the exercise
of this Warrant) shall thereafter be applicable, as nearly as may be possible,
in relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise hereof.  The Company will not effect any such consolidation,
merger or sale unless, prior to the consummation thereof, the successor
corporation (if other than the Company) resulting from such consolidation or the
corporation purchasing such assets shall assume by written instrument, executed
and mailed or delivered to the registered Holder hereof at the last address of
such Holder appearing on the books of the Company, the obligation to deliver to
such Holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such Holder may be entitled to purchase.

          4.4  Sale or Issuance Below Purchase Price.  If the Company shall at
               -------------------------------------                          
any time or from time to time issue or sell any of its Common Stock, Common
Stock, options to acquire (or rights to acquire such options), or any other
securities convertible into or exercisable for Common Stock, for a consideration
per share less than the Stock Purchase Price in effect immediately prior to the
time of such issue or sale, the Stock Purchase Price then in effect and then
applicable for any subsequent period or periods shall be adjusted to a price
determined by dividing (i) an amount equal to the sum of (x) the number of
shares of Common Stock outstanding immediately prior to such issue or sale
multiplied by the Stock Purchase Price then in effect and (y) the consideration,
if any, received by the Company upon such issue or sale, by (ii) the total
number of shares of Common Stock outstanding immediately after such issue or
sale.  For purposes of this Section 4.4, all shares of Common Stock issuable
upon the exercise and/or conversion of all outstanding warrants (including this
Warrant), options and convertible securities shall be deemed to be outstanding.
The foregoing notwithstanding, no adjustment shall be made pursuant to this
Section 4.4 on account of a given sale to the extent that (a) the Stock 

                                       5

 
Purchase Price is adjusted pursuant to any other Section of this Warrant or (b)
the conversion price of the Common Stock is decreased pursuant to the terms
thereof.

          4.5  Notice of Adjustment.  Upon any adjustment of the Stock Purchase
               --------------------                                            
Price, and/or any increase or decrease in the number of shares purchasable upon
the exercise of this Warrant the Company shall give written notice thereof, by
first class mail, postage prepaid, addressed to the registered holder of this
Warrant at the address of such holder as shown on the books of the Company.  The
notice shall be signed by the Company's chief financial officer and shall state
the Stock Purchase Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares purchasable at such price upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

          4.6  Other Notices.  If at any time:
               -------------                  

               (a)  the Company shall declare any cash dividend upon its Common
Stock;

               (b)  the Company shall declare any dividend upon its Common Stock
payable in stock or make any special dividend or other distribution to the
holders of its Common Stock;

               (c)  the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or other
rights;

               (d)  there shall be any capital reorganization or
reclassification of the capital stock of the Company, or consolidation or merger
of the Company with, or sale of all or substantially all of its assets to,
another corporation;

               (e)  there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company; or

               (f)  the Company shall take or propose to take any other action,
notice of which is actually provided to holders of the Common Stock;

then, in any one or more of said cases, the Company shall give, by first class
mail, postage prepaid, addressed to the holder of this Warrant at the address of
such holder as shown on the books of the Company, (i) at least 20 day's prior
written notice of the date on which the books of the Company shall close or a
record shall be taken for such dividend, distribution or subscription rights or
for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action and (ii) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
windingup, or other action, at least 20 day's written notice of the date when
the same shall take place. Any notice given in accordance with the foregoing
clause (i) shall also specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto. Any notice given in accordance with the

                                       6

 

foregoing clause (ii) shall also specify the date on which the holders of Common
Stock shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation or winding-up, or other action as the
case may be.

          4.7  Certain Events.  If any change in the outstanding Common Stock of
               --------------                                                   
the Company or any other event occurs as to which the other provisions of this
Section 4 are not strictly applicable or if strictly applicable would not fairly
protect the purchase rights of the Holder of the Warrant in accordance with the
essential intent and principles of such provisions, then the Board of Directors
of the Company shall make an adjustment in the number and class of shares
available under the Warrant, the Stock Purchase Price and/or the application of
such provisions, in accordance with such essential intent and principles, so as
to protect such purchase rights as aforesaid.  The adjustment shall be such as
will give the Holder of the Warrant upon exercise for the same aggregate Stock
Purchase Price the total number, class and kind of shares as he would have owned
had the Warrant been exercised prior to the event and had he continued to hold
such shares until after the event requiring adjustment.

     5.   Issue Tax.  The issuance of certificates for shares of Common Stock
          ---------                                                          
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax in respect thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Holder of the Warrant being exercised.

     6.   Closing of Books.  The Company will at no time close its transfer
          ----------------
books against the transfer of any Warrant or of any shares of Common Stock
issued or issuable upon the exercise of any warrant in any manner which
interferes with the timely exercise of this Warrant.

     7.   No Voting or Dividend Rights; Limitation of Liability.  Nothing
          -----------------------------------------------------          
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent as a shareholder in respect of meetings
of shareholders for the election of directors of the Company or any other
matters or any rights whatsoever as a shareholder of the Company.  No dividends
or interest shall be payable or accrued in respect of this Warrant or the
interest represented hereby or the shares purchasable hereunder until, and only
to the extent that, this Warrant shall have been exercised.  No provisions
hereof, in the absence of affirmative action by the holder to purchase shares of
Common Stock, and no mere enumeration herein of the rights or privileges of the
Holder hereof, shall give rise to any liability of such Holder for the Stock
Purchase Price or as a shareholder of the Company, whether such liability is
asserted by the Company or by its creditors.

     8.   Amendment of Articles of Incorporation.  Unless the holder of this
          --------------------------------------                            
Warrant consents thereto in writing, the Company shall not amend its Articles of
Incorporation prior to the exercise of this Warrant if the Common Stock would be
adversely affected by such amendment.

     9.   Registration Rights.  The Holder hereof shall be entitled, with
          -------------------
respect to the shares of Common Stock issued upon exercise hereof or the shares
of Common Stock or other 

                                       7

 
securities issued upon conversion of such Common Stock as the case may be, to
all of the registration rights set forth in the Registration Rights
Agreement/Stock Purchase Agreement dated as of ___________________ to the same
extent and on the same terms and conditions as possessed by the [class of
Investors/Purchasers thereunder]. The company shall take such action as may be
reasonably necessary to assure that the granting of such registration rights to
the Holder does not violate the provisions of such agreement or any of the
Company's charter documents or rights of prior Grantees of registration rights.

     10.  Rights and Obligations Survive Exercise of Warrant.  The rights and
          --------------------------------------------------                 
obligations of the Company, of the Holder of this Warrant and of the holder of
shares of Common Stock issued upon exercise of this Warrant, contained in
Sections 6, 8 and 9 shall survive the exercise of this Warrant.

     11.  Modification and Waiver.  This Warrant and any provision hereof may be
          -----------------------

signed by the party against which enforcement of the same is sought.

          -------

have been given (i) upon receipt if delivered personally or by courier (ii) upon
confirmation of receipt if by telecopy or (iii) three business days after
deposit in the US mail, with postage prepaid and certified or registered, to
each such holder at its address as shown on the books of the Company or to the
Company at the address indicated therefor in the first paragraph of this
Warrant.

     13.  Binding Effect on Successors.  This Warrant shall be binding upon any
          ----------------------------                                         
corporation succeeding the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets.  All of the obligations of the
Company relating to the Common Stock issuable upon the exercise of this Warrant
shall survive the exercise and termination of this Warrant.  All of the
covenants and agreements of the Company shall inure to the benefit of the
successors and assign of the holder hereof.  The Company will, at the time of
the exercise of this Warrant, in whole or in part, upon request of the Holder
hereof but at the Company's expense, acknowledge in writing its continuing
obligation to the Holder hereof in respect of any rights (including, without
limitation, any right to registration of the shares of Common Stock) to which
the holder hereof shall continue to be entitled after such exercise in
accordance with this Warrant; provided, that the failure of the holder hereof to
make any such request shall not affect the continuing obligation of the Company
to the Holder hereof in respect of such rights.

     14.  Descriptive Headings and Governing Law.  The descriptive headings of
          --------------------------------------

cancellation of such Warrant or stock certificate, the Company at its expense
will make and deliver a new Warrant or stock certificate, of like tenor, in lieu
of the lost, stolen, destroyed or mutilated Warrant or stock certificate.

     16.  Fractional Shares.  No fractional shares shall be issued upon exercise
          -----------------
