     2.02  Use of Proceeds; the Loans and the Loan Terms Schedules.

     (a)  Use of Proceeds.  The proceeds of the Loans shall be used solely for
the purchase of, or reimbursement to Borrower of the Stated Cost of, Equipment.

     (b)  The Loans.  The obligation of Borrower to repay the aggregate unpaid
principal amount of and accrued but unpaid interest on and to make the Final
Payments on the Loans, or to pay the Loan Value of the Loan Amount applicable to
each Loan, shall be evidenced by a Loan Terms Schedule which shall be considered
a promissory note evidencing the amounts due under such Loan.

     2.03 Procedure for Making Loans.

     (a)  Loan Terms Schedule.  Whenever Borrower desires that Lender make a
Loan, Borrower shall deliver to Lender a list of the Equipment proposed to be
financed by such Loan and request that Lender prepare a Loan Terms Schedule for
such Loan. Lender's obligations to make the initial Loan shall be subject to the
satisfaction of the conditions set forth in Section 8.01 and 8.02. Lender's
obligation to make each subsequent Loan shall be subject to the satisfaction of
the conditions set forth in Section 8.02.

     (b)  Loan Interest Rate.  Borrower shall pay interest on the unpaid
principal amount of each Loan from the first Payment Date for such Loan until
such Loan is paid in full, at a per annum rate of interest equal to the Loan
Rate determined by Lender as of the Funding Date for such Loan in accordance
with the definition of Loan Rate. The Loan Rate applicable to each Loan shall
not be subject to change in the absence of manifest error. All computations of
interest on Loans shall be based on a year of twelve 30 day months. If Borrower
pays interest on any Loan which is determined to be in excess of the then legal
maximum rate, then that portion of each interest payment representing an amount
in excess of the then legal maximum rate shall be deemed a payment of principal
and applied against the principal of the applicable Loan.

     (c)  Loan Factor and Loan Value Calculation.  Each Loan Terms Schedule
shall establish the Loan Factor and Loan Values with respect to such Loan. The
Loan Factor shall be calculated to a manner to fully amortize the Loan over the
Repayment Period applicable to such Loan to equal periodic installments. The
Loan Factor and Loan Values applicable to each Loan shall be conclusive in the
absence of manifest error.

     (d)  Disbursement.  Subject to the receipt by Lender of a Loan Terms
Schedule duly executed by Borrower and the satisfaction of the conditions set
forth to Sections 8.01 and 8.02 with respect to the initial Loan and the
satisfaction of the conditions set forth in Section 8.02 with respect to each
subsequent Loan, Lender shall disburse such Loan by wire transfer to Borrower
unless otherwise directed in writing by Borrower.

     (e)  Termination of Commitment to Lend.  Notwithstanding anything to the
contrary to the Operative Documents, Lenders obligation to lend the undisbursed
portion of the Credit Amount to Borrower hereunder shall terminate on the
earlier of (i) the occurrence of any Event of Default hereunder and (ii)the
Commitment Termination Date.

     2.04.  Other Payment Terms.

     (a)  Principal and Interest Payments On Payment Dates.  Borrower shall make
payments of principal and accrued interest in advance for each Loan
(collectively, "Scheduled Payments"), commencing on the date set forth on the
Loan Terms Schedule applicable to such Loan and continuing thereafter during the
Repayment Period on the first Business Day of each calendar month (each a
"Payment Date"), in an amount equal to the Loan Factor multiplied by the Loan
Amount for such Loan as of such Payment Date, provided however, that the last
Scheduled Payment which would otherwise be made in the last month of such
Repayment Period shall be paid in advance on the Funding Date. The Loans may not
be prepaid except in the circumstances set forth in Section 6.01(e).

     (b)  Interim Payment.  Unless the Funding Date for a Loan is a Payment
Date, Borrower shall pay to Lender the Interim Payment payable with respect to
such Loan on the date specified in the Loan Terms Schedule applicable to such
Loan.

     (c)  Final Payment.  Unless a Loan-is prepaid in full, on the Maturity Date
with respect to such Loan, Borrower shall pay, to addition to any remaining
unpaid principal and accrued interest and all other amounts previously due with
respect to such Loan, an amount equal to the Final Payment with respect to such
Loan.

     (d)  The Good Faith Deposit.  Borrower has paid a good faith deposit in the
amount of $15.000 (the "Deposit"). Any portion of the Deposit not utilized to
pay Lender's expenses in connection with Lender's due diligence and the
negotiation, documentation and funding of the Loans will be applied by Lender to
amounts due under the Loans in the order in which such amounts are due. If Loans
are not made, any remaining balance of the Deposit shall be retained by Lender.

     (e)  Place and Manner.  Borrower shall make all payments due to Lender in
lawful money of the United States at the address for payments and in the manner
specified in Section 10.05(b).

     (f)  Date.  Whenever any payment due hereunder shall fall due on a day
other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall be included to the computation of
interest or fees, as the case may be.

     (g)  Default Ram.  If either (i) any amounts required to be paid by
Borrower under this Agreement or the other Operative Documents (including
principal or interest payable on any Loan, any fees or other amounts) remain
unpaid after such amounts are due, or Q) an Event of Default has occurred and is
continuing, Borrower shall pay interest on the aggregate, outstanding principal
balance hereunder from the date due or from the date of the Event of Default, as
applicable, until such past due amounts are paid to full or until all Events of
Defaults are cured, as applicable, at a per annum rate equal to the Default
Rate. All computations of such interest shall be based on a year of twelve
30-day months.

     (h)  Optional Prepayment.  At any time on or after the first anniversary of
the earlier of (i) the Commitment Termination Date or (ii) the Funding Date of
the Final Loan, and upon ten (10) Business Days' prior written nonce to Lender,
Borrower may, at its option, prepay all, and

                                       8

<PAGE>

not less than all, of the Loans to full by paying to Lender an amount equal to
(i) all accrued and unpaid Scheduled Payments with respect to each Loan due on
or prior to the date of prepayment; (ii) the sum of all remaining unpaid
Scheduled Payments discounted to present value to the date of prepayment at
seven percent (7%) per annum: (iii) the sum of all Final Payments discounted to
present value to the date of prepayment at seven percent (7%) per annum: and (v)
all other sums, if any, that shall have become due and payable hereunder. If an
Event of Default occurs and is continuing, and the Lender exercises its right
under Section 9.02 to accelerate the Loans or the Loans are automatically
accelerated, Borrower expressly agrees that the amount then due and payable
shall be equal to (i) all accrued and unpaid Scheduled Payments on each Loan due
on or prior to the date of acceleration, (n) the Loan Value of each Loan, and
(iii) all other sums, if any, that shall have become due and payable hereunder
as of the date of such acceleration. Except as set forth in this Section
2.04(h), the Loans may not be prepaid.

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

                       THIS LANDLORD'S WAIVER AND CONSENT

          property commonly known as ______________________, and more
          particularly described in Attachment 1 hereto (the "Premises").

     B.   Tenant and Lender intend to or have entered into a Loan and Security
          Agreement dated as of April __, 2001 (the "Loan Agreement") pursuant
          to which Lender has agreed or will agree to make loans to Tenant from
          time to rime secured by certain equipment (the "Equipment") which will
          be located on the Premises.


                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Landlord and Lender hereby agree as follows:

     1.   Waiver and Consent.  Landlord hereby consents to the location of the
          Equipment on the Premises and does irrevocably waive, disclaim and
          relinquish and assign to Lender any and all rights to impose, receive,
          assert or enforce any lien, encumbrance, charge, security interest,
          ownership interest, claim or demand of any kind against or involving
          the Equipment, whether arising by common law, statute or consensually

<PAGE>

          fixture attached to, the Premises, notwithstanding the manner of the

          purposes for which the Premises are used, and the intentions of the
          party mating the annexation; (b) the Equipment (or any item thereof)
          may be repossessed by Lender, (c) in connection with such repossession
          or otherwise, Lender, and any of its agents and employees, may enter
          upon the Premises for the purposes of preparing for transport,
          disassembling, dismantling, loading and/or removing the Equipment (or
          any item thereof); and (d) the right of Lender to enter the Premises
          and the other rights granted to Lender in this Waver shall not
          terminate until up to thirty (30) days after Lender receives written
          nonce from Landlord of the termination of the Lease; provided, that if
          Lender exercises its rights hereunder, for any such period after the
          termination of the Lease. Lender shall pay to Landlord a pro rated
          rental payment for the space to which the Equipment is located (at the
          last monthly rate payable by Tenant) for the period until the
          Equipment is removed.

     2.   Costs.  Lender agrees to indemnify and hold the Landlord harmless from
          any out-of-pocket costs incurred by Landlord for any physical damage

          rights under clauses (b) or (c) of Paragraph 1 above.

     3.   Lease Defaults.  Landlord further agrees to provide Lender with
          telephonic confirmation of any default or event of default under the
          Lease upon inquiry by Lender.

     4.   Landlord's Representations and Warranties.  Landlord hereby warrants
          and represents to Lender that (a) Landlord is the lessor under the
          Lease; (b) them are no other agreements between the parties affecting
          or relating to the Premises; (c) Landlord has all requisite power and
          authority to execute and deliver this Waiver and no consents from any
          third party are required to do so; (d) no event of default (nor any
          event which with the passage of time would constitute an event of
          default) has occurred under the Lease; (e) there exists no litigation
          affecting title to the Premises or any adverse claim with respect to
          the Premises of which Landlord has received notice; and (f) there is
          no condemnation proceeding pending with respect to any part of the
          Premises, nor any threat thereof, of which the Landlord has received
          notice.

     5.   Miscellaneous.  This Waiver and all rights hereby granted to Lender
          hereunder shall remain in effect so long as there are any obligations
          owing by Tenant under the Loan Agreement or any present or future
          agreement between Tenant and Lender which involves the Equipment. All
          the terms and provisions of this Waiver shall be binding on and inure
          to the benefit of the respective successors and, assigns of Landlord
          and Lender. The rights and benefits of this Waiver may be assigned or
          transferred by Lender or to third parties who may become the lender,
          directly or indirectly, to Tenant. Lender shall provide subsequent
          written nonce to Landlord and Tenant of the assignment or transfer.

THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION MAY BE EFFECTED
WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO, (ii) AN OPINION
OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH

                          NETSCREEN TECHNOLOGIES, INC.

                        WARRANT TO PURCHASE 20,642 SHARES
                           OF SERIES E PREFERRED STOCK

     THIS CERTIFIES THAT, for value received, GATX VENTURES, INC. and its
assignees are entitled to subscribe for and purchase 20,642 shares of the fully
paid and nonassessable Series E Preferred Stock (as adjusted pursuant to Section
4 hereof, the "Shares") of NETSCREEN TECHNOLOGIES, INC., a Delaware corporation
(the "Company"), at the price of $7.63 per share (such price and such other
price as shall result, from time to time, from the adjustments specified in
Section 4 hereof is herein referred to as the "Warrant Price"), subject to the
provisions and upon the terms and conditions hereinafter set forth. As used
herein, (a) the term "Series Preferred" shall mean the Company's presently
authorized Series E Preferred Stock, and any stock into or for which such Series
E Preferred Stock may hereafter be converted or exchanged, and after the
automatic conversion of the Series E Preferred Stock to Common Stock shall mean
the Company's Common Stock, (b) the term "Date of Grant" shall mean April 13,
2001, and (c) the term "Other Warrants" shall mean any other warrants issued by
the Company in connection with the transaction with respect to which this
Warrant was issued, and any warrant issued upon transfer or partial exercise of
or in lieu of this Warrant. The term "Warrant" as used herein shall be deemed to
include Other Warrants unless the context clearly requires otherwise.

     1.  Term. The purchase right represented by this Warrant is exercisable, in
         ----
whole or in part, at any time and from time to time from the Date of Grant
through the later of (i) ten (10) years after the Date of Grant or (ii) five (5)
years after the closing of the Company's initial public offering of its Common
Stock ("IPO") effected pursuant to a Registration Statement on Form S-1 (or its
successor) filed under the Securities Act of 1933, as amended (the "Act").
Upon request of the Company, the holder of this Warrant agrees to exercise the
purchase right under this Warrant (including without limitation by way of net
issuance as provided in Section 10.2) contemporaneously with the closing of a
merger or consolidation in which the Company is not the surviving corporation,
the sale, lease, exchange, conveyance or other disposition of all or
substantially all of the assets of the Company or the purchase by a person or
group of related persons of all of the outstanding capital stock of the Company
if (A) the Company receives solely cash in consideration for such sale or
merger, (B) the acquiror in such sale or merger has a net worth as of the end of
its most recent fiscal year in excess of $200,000,000; or (C) the net proceeds
per share to the holder of this Warrant upon

<PAGE>

such exercise will equal at least the product of the Warrant Price multiplied by
2.5. The Company agrees to provide the holder of this Warrant not less than
twenty (20) days' prior written notice of the Company's request that the holder
exercise its purchase right hereunder in accordance with the provisions of
Section 13 hereof. The holder agrees to exercise this Warrant (including without
limitation, via a net issuance) upon or prior to an IPO so long as the
underwriters of such IPO certify to holder in writing that (i) such underwriters
have determined that the failure of the holder to exercise this Warrant would
have a material negative economic impact upon the offering, and (ii) the
underwriters have required all warrant holders of the Company to exercise their
warrants prior to the offering.

     2.  Method of Exercise; Payment; Issuance of New Warrant. Subject to
         ----------------------------------------------------
Section 1 hereof, the purchase right represented by this Warrant may be
exercised by the holder hereof, in whole or in part and from time to time, at
the election of the holder hereof, by (a) the surrender of this Warrant (with
the notice of exercise substantially in the form attached hereto as Exhibit A-1
duly completed and executed) at the principal office of the Company and by the
payment to the Company, by certified or bank check, or by wire transfer to an
account designated by the Company (a "Wire Transfer") of an amount equal to the
then applicable Warrant Price multiplied by the number of Shares then being
purchased; (b) if in connection with a registered public offering of the
Company's securities, the surrender of this Warrant (with the notice of exercise
form attached hereto as Exhibit A-2 duly completed and executed) at the
principal office of the Company together with notice of arrangements reasonably
satisfactory to the Company for payment to the Company either by certified or
bank check or by Wire Transfer from the proceeds of the sale of shares to be
sold by the holder in such public offering of an amount equal to the then
applicable Warrant Price per share multiplied by the number of Shares then being
purchased; or (c) exercise of the "net issuance" right provided for in Section
10.2 hereof. The person or persons in whose name(s) any certificate(s)
representing shares of Series Preferred shall be issuable upon exercise of this
Warrant shall be deemed to have become the holder(s) of record of, and shall be
treated for all purposes as the record holder(s) of, the shares represented
thereby (and such shares shall be deemed to have been issued) immediately prior
to the close of business on the date or dates upon which this Warrant is
exercised. In the event of any exercise of the rights represented by this
Warrant, certificates for the shares of stock so purchased shall be delivered to
the holder hereof as soon as possible and in any event within thirty (30) days
after such exercise and, unless this Warrant has been fully exercised or
expired, a new Warrant representing the portion of the Shares, if any, with
respect to which this Warrant shall not then have been exercised shall also be
issued to the holder hereof as soon as possible and in any event within such
thirty-day period; provided, however, at such time as the Company is subject to
the reporting requirements of the Securities Exchange Act of 1934, as amended,
if requested by the holder of this Warrant, the Company shall cause its transfer
agent to deliver the certificate representing Shares issued upon exercise of
this Warrant to a broker or other person (as directed by the holder exercising
this Warrant) within the time period required to settle any trade made by the
holder after exercise of this Warrant.

     3.  Stock Fully Paid; Reservation of Shares. All Shares that may be issued
         ---------------------------------------
upon the exercise of the rights represented by this Warrant will, upon issuance
pursuant to the terms and conditions herein, be fully paid and nonassessable,
and free from all taxes and charges with respect

                                      -2-

<PAGE>

to the issue thereof. 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 the issue upon exercise of the purchase rights
evidenced by this Warrant, a sufficient number of shares of its Series Preferred
to provide for the exercise of the rights represented by this Warrant and a
sufficient number of shares of its Common Stock to provide for the conversion of
the Series Preferred into Common Stock.

     4.  Adjustment of Warrant Price and Number of Shares. The number and kind
         ------------------------------------------------
of securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the occurrence of
certain events, as follows:

         (a)  Reclassification or Merger. In case of any reclassification or
              --------------------------
change of securities of the class issuable upon exercise of this Warrant (other
than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), or in case
of any merger of the Company with or into another corporation (other than a
merger with another corporation in which the Company is the acquiring and the
surviving corporation and which does not result in any reclassification or
change of outstanding securities issuable upon exercise of this Warrant), or in
case of any sale of all or substantially all of the assets of the Company, the
Company, or such successor or purchasing corporation, as the case may be, shall
duly execute and deliver to the holder of this Warrant a new Warrant (in form
and substance satisfactory to the holder of this Warrant), or the Company shall
make appropriate provision without the issuance of a new Warrant, so that the
holder of this Warrant shall have the right to receive upon exercise of this
Warrant, at a total purchase price not to exceed that payable upon the exercise
of the unexercised portion of this Warrant, and in lieu of the shares of Series
Preferred theretofore issuable upon exercise of this Warrant, the kind and
amount of shares of stock, other securities, money and property receivable upon
such reclassification, change, merger or sale by a holder of the number of
shares of Series Preferred then purchasable under this Warrant and having a
value at the time of the transaction equivalent to the value of the Series
Preferred purchasable upon exercise of this Warrant at the time of the
transaction. Any new Warrant shall provide for adjustments that shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section 4. The provisions of this subparagraph (a) shall similarly apply to
successive reclassifications, changes, mergers and transfers.

         (b)  Subdivision or Combination of Shares. If the Company at any time
              ------------------------------------
while this Warrant remains outstanding and unexpired shall subdivide or combine
its outstanding shares of Series Preferred, the Warrant Price shall be
proportionately decreased and the number of Shares issuable hereunder shall be
proportionately increased in the case of a subdivision and the Warrant Price
shall be proportionately increased and the number of Shares issuable hereunder
shall be proportionately decreased in the case of a combination.

         (c)  Stock Dividends and Other Distributions. If the Company at any
              ---------------------------------------
time while this Warrant is outstanding and unexpired shall (i) pay a stock
dividend with respect to Series Preferred payable in Series Preferred, then the
Warrant Price shall be adjusted, from and after the date of determination of
shareholders entitled to receive such dividend or distribution, to that price

                                      -3-

<PAGE>

determined by multiplying the Warrant Price in effect immediately prior to such
date of determination by a fraction (A) the numerator of which shall be the
total number of shares of Series Preferred outstanding immediately prior to such
dividend or distribution, and (B) the denominator of which shall be the total
number of shares of Series Preferred outstanding immediately after such dividend
or distribution; or (ii) make any other distribution with respect to Series
Preferred (except any distribution specifically provided for in Sections 4(a)
and 4(b)), then, in each such case, provision shall be made by the Company such
that the holder of this Warrant shall receive upon exercise of this Warrant a
proportionate share of any such dividend or distribution as though it were the
holder of the Series Preferred (or Common Stock issuable upon conversion
thereof) as of the record date fixed for the determination of the shareholders
of the Company entitled to receive such dividend or distribution.

         (d)  Adjustment of Number of Shares. Upon each adjustment in the
              ------------------------------
Warrant Price, the number of Shares of Series Preferred purchasable hereunder
shall be adjusted, to the nearest whole share, to the product obtained by
multiplying the number of Shares purchasable immediately prior to such
adjustment in the Warrant Price by a fraction, the numerator of which shall be
the Warrant Price immediately prior to such adjustment and the denominator of
which shall be the Warrant Price immediately thereafter.

         (e)  Antidilution Rights. The other antidilution rights applicable to
              -------------------
the Shares of Series Preferred purchasable hereunder are set forth in the
Company's Certificate of Incorporation, as amended through the Date of Grant, a
true and complete copy of which is attached hereto as Exhibit B (the "Charter").
Such antidilution rights shall not be restated, amended, modified or waived in
any manner without holder's prior written consent if the effect of such
restatement, amendment, modification or waiver on the holder hereof would be
more adverse to the holder hereof than, and substantially dissimilar to, its
effect on the other holders of the Company's Series Preferred. The Company shall
promptly provide the holder hereof with any restatement, amendment, modification
or waiver of the Charter promptly after the same has been made.

     5.  Notice of Adjustments. Whenever the Warrant Price or the number of
         ---------------------
Shares purchasable hereunder shall be adjusted pursuant to Section 4 hereof, the
Company shall make a certificate signed by its chief financial officer or other
appropriate officer setting forth, in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated, and the Warrant Price and the number of Shares purchasable
hereunder after giving effect to such adjustment, and shall cause copies of such
certificate to be mailed (without regard to Section 13 hereof, by first class
mail, postage prepaid) to the holder of this Warrant. In addition, whenever the
conversion price or conversion ratio of the Series Preferred shall be adjusted,
the Company shall make a certificate signed by its chief financial officer or
other appropriate officer setting forth, in reasonable detail, the event
requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated, and the conversion price or ratio of the Series
Preferred after giving effect to such adjustment, and shall cause copies of such
certificate to be mailed (without regard to Section 13 hereof, by first class
mail, postage prepaid) to the holder of this Warrant.

                                      -4-

<PAGE>

     6.  Fractional Shares. No fractional shares of Series Preferred will be
         -----------------
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor based on the fair market
value of the Series Preferred on the date of exercise as reasonably determined
in good faith by the Company's Board of Directors.

     7.  Compliance with Act; Disposition of Warrant or Shares of Series
         ---------------------------------------------------------------
Preferred.
---------

         (a)  Compliance with Act. The holder of this Warrant, by acceptance
              -------------------
hereof, agrees that this Warrant, and the shares of Series Preferred to be
issued upon exercise hereof and any Common Stock issued upon conversion thereof
are being acquired for investment and that such holder will not offer, sell or
otherwise dispose of this Warrant, or any shares of Series Preferred to be
issued upon exercise hereof or any Common Stock issued upon conversion thereof
except under circumstances which will not result in a violation of the Act or
any applicable state securities laws. Upon exercise of this Warrant, unless the
Shares being acquired are registered under the Act and any applicable state
securities laws or an exemption from such registration is available, the holder
hereof shall confirm in writing that the shares of Series Preferred so purchased
(and any shares of Common Stock issued upon conversion thereof) are being
acquired for investment and not with a view toward distribution or resale in
violation of the Act and shall confirm such other matters related thereto as may
be reasonably requested by the Company. This Warrant and all shares of Series
Preferred issued upon exercise of this Warrant and all shares of Common Stock
issued upon conversion thereof (unless registered under the Act and any
applicable state securities laws) shall be stamped or imprinted with a legend in
substantially the following form:

"THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. NO SALE OR DISPOSITION
MAY BE EFFECTED WITHOUT (i) EFFECTIVE REGISTRATION STATEMENTS RELATED THERETO,
(ii) AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE
COMPANY, THAT SUCH REGISTRATIONS ARE NOT REQUIRED, (iii) RECEIPT OF NO-ACTION
LETTERS FROM THE APPROPRIATE GOVERNMENTAL AUTHORITIES, OR (iv) OTHERWISE
COMPLYING WITH THE PROVISIONS OF SECTION 7 OF THE WARRANT UNDER WHICH THESE
SECURITIES WERE ISSUED, DIRECTLY OR INDIRECTLY."

     Said legend shall be removed by the Company, upon the request of a holder,
at such time as the restrictions on the transfer of the applicable security
shall have terminated. In addition, in connection with the issuance of this
Warrant, the holder specifically represents to the Company by acceptance of this
Warrant as follows:

              (1)  The holder is aware of the Company's business affairs and
financial condition, and has acquired information about the Company sufficient
to reach an informed and knowledgeable decision to acquire this Warrant. The
holder is acquiring this Warrant for its own account for investment purposes
only and not with a view to, or for the resale in connection with, any
"distribution" thereof in violation of the Act.

                                       -5-

<PAGE>

              (2)  The holder understands that this Warrant has not been
registered under the Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of the holder's
investment intent as expressed herein.

              (3)  The holder further understands that this Warrant must be held
indefinitely unless subsequently registered under the Act and qualified under
any applicable state securities laws, or unless exemptions from registration and
qualification are otherwise available. The holder is aware of the provisions of
Rule 144, promulgated under the Act.

              (4)  The holder is an "accredited investor" as such term is
defined in Rule 501 of Regulation D promulgated under the Act.

         (b)  Disposition of Warrant or Shares. With respect to any offer, sale
              --------------------------------
or other disposition of this Warrant or any shares of Series Preferred acquired
pursuant to the exercise of this Warrant prior to registration of such Warrant
or shares, the holder hereof agrees to give written notice to the Company prior
thereto, describing briefly the manner thereof, together with a written opinion
of such holder's counsel, or other evidence, if reasonably satisfactory to the
Company, to the effect that such offer, sale or other disposition may be
effected without registration or qualification (under the Act as then in effect
or any federal or state securities law then in effect) of this Warrant or such
shares of Series Preferred or Common Stock and indicating whether or not under
the Act certificates for this Warrant or such shares of Series Preferred to be
sold or otherwise disposed of require any restrictive legend as to applicable
restrictions on transferability in order to ensure compliance with such law.
Upon receiving such written notice and reasonably satisfactory opinion or other
evidence, the Company, as promptly as practicable but no later than fifteen (15)
days after receipt of the written notice, shall notify such holder that such
holder may sell or otherwise dispose of this Warrant or such shares of Series
Preferred or Common Stock, all in accordance with the terms of the notice
delivered to the Company. If a determination has been made pursuant to this
Section 7(b) that the opinion of counsel for the holder or other evidence is not
reasonably satisfactory to the Company, the Company shall so notify the holder
promptly with details thereof after such determination has been made.
Notwithstanding the foregoing, this Warrant or such shares of Series Preferred
or Common Stock may, as to such federal laws, be offered, sold or otherwise
disposed of in accordance with Rule 144 or 144A under the Act, provided that the
Company shall have been furnished with such information as the Company may
reasonably request to provide a reasonable assurance that the provisions of Rule
144 or 144A have been satisfied. Each certificate representing this Warrant or
the shares of Series Preferred thus transferred (except a transfer pursuant to
Rule 144) shall bear a legend as to the applicable restrictions on
transferability in order to ensure compliance with such laws, unless in the
aforesaid opinion of counsel for the holder, such legend is not required in
order to ensure compliance with such laws. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

         (c)  Applicability of Restrictions. Neither any restrictions of any
              -----------------------------
legend described in this Warrant nor the requirements of Section 7(b) above
shall apply to any transfer of, or grant of a security interest in, this Warrant
(or the Series Preferred or Common Stock obtainable upon exercise thereof) or
any part hereof (i) to a partner of the holder if the holder is a partnership or
to a member

                                      -6-

<PAGE>

of the holder if the holder is a limited liability company, (ii) to a
partnership of which the holder is a partner or to a limited liability company
of which the holder is a member, or (iii) to any affiliate of the holder if the
holder is a corporation; provided, however, in any such transfer, if applicable,
the transferee shall on the Company's request agree in writing to be bound by
the terms of this Warrant as if an original holder hereof.

     8.  Rights as Shareholders; Information. No holder of this Warrant, as
         -----------------------------------
such, shall be entitled to vote or receive dividends or be deemed the holder of
Series Preferred or any other securities of the Company which may at any time be
issuable on the exercise hereof for any purpose, nor shall anything contained
herein be construed to confer upon the holder of this Warrant, as such, any of
the rights of a shareholder of the Company or any right to vote for the election
of directors or upon any matter submitted to shareholders at any meeting
thereof, or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until this Warrant shall have been exercised
and the Shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein. Notwithstanding the foregoing, the Company will
transmit to the holder of this Warrant such information, documents and reports
as are generally distributed to the holders of any class or series of the
securities of the Company concurrently with the distribution thereof to the
shareholders.

     9.  Registration Rights. The Company has secured all approvals necessary to
         -------------------
amend its Fourth Amended and Restated Investor Rights Agreement, dated as of
June 30, 2000 (the "Rights Agreement") to include the holder hereof as a party
to the Rights Agreement for the purpose of granting it "piggyback" registration
rights as set forth in Section 2.3 of the Rights Agreement (but not demand or
S-3 registration rights) with respect to any Common Stock of the Company
obtained upon conversion of the Series Preferred (the "Conversion Stock").
Holder has executed and delivered to the Company a counterpart signature page to
the Rights Agreement for the purpose of receiving such piggyback registration
rights and becoming bound by all related provisions of the Rights Agreement
(including the indemnification provisions of Section 2.8 and the market standoff
provisions of Section 2.9). The registration rights granted to holder may be
transferred to an acquiror of the Warrant or of all of the shares acquired upon
warrant exercise, or as otherwise permitted by the Rights Agreement.

    10.  Additional Rights.
         -----------------

         10.1    Acquisition Transactions. The Company shall provide the holder
                 ------------------------
of this Warrant with at least twenty (20) days' written notice prior to closing
thereof of the terms and conditions of any of the following transactions (to the
extent the Company has notice thereof): (i) the sale, lease, exchange,
conveyance or other disposition of all or substantially all of the Company's
property or business, or (ii) its merger into or consolidation with any other
corporation (other than a wholly-owned subsidiary of the Company), or any
transaction (including a merger or other reorganization) or series of related
transactions, in which more than 50% of the voting power of the Company is
transferred to another corporation or person(s).

         10.2    Right to Convert Warrant into Stock:  Net Issuance.
                 --------------------------------------------------

         (a)  Right to Convert. In addition to and without limiting the rights
              ----------------
of the holder under the terms of this Warrant, the holder shall have the right
to convert this Warrant or any portion thereof (the "Conversion Right") into
shares of Series Preferred (or Common Stock if the Series Preferred has been
automatically converted into Common Stock) as provided in this Section 10.2 at
any time or from time to time during the term of this Warrant. Upon exercise of
the Conversion Right with respect to a particular number of shares subject to
this Warrant (the "Converted Warrant Shares"), the Company shall deliver to the
holder (without payment by the holder of any exercise price or any cash or other
consideration) that number of shares of fully paid and nonassessable Series
Preferred (or Common Stock if the Series Preferred has been automatically
converted into Common Stock) as is determined according to the following
formula:

      X   =   B - A
            ---------
                Y

      Where:   X  =       the number of shares of Series Preferred (or Common
                          Stock if the Series Preferred has been automatically
                          converted to Common Stock) that shall be issued to
                          holder

               Y  =       the fair market value of one share of Series Preferred
                          (or Common Stock if the Series Preferred has been
                          automatically converted to Common Stock)

               A  =       the aggregate Warrant Price of the specified number of
                          Converted Warrant Shares immediately prior to the
                          exercise of the Conversion Right (i.e., the number of
                          Converted Warrant Shares multiplied by the Warrant
                          Price)

               B  =       the aggregate fair market value of the specified
                          number of Converted Warrant Shares (i.e., the number
                          of Converted Warrant Shares multiplied by the fair
                          market value of one Converted Warrant Share)

     No fractional shares shall be issuable upon exercise of the Conversion
Right, and, if the number of shares to be issued determined in accordance with
the foregoing formula is other than a whole number, the Company shall pay to the
holder an amount in cash equal to the fair market value of the resulting
fractional share on the Conversion Date (as hereinafter defined). For purposes
of Section 9 of this Warrant, shares issued pursuant to the Conversion Right
shall be treated as if they were issued upon the exercise of this Warrant.

         (b)  Method of Exercise. The Conversion Right may be exercised by the
              ------------------
holder by the surrender of this Warrant at the principal office of the Company
together with a written statement (which may be in the form of Exhibit A-1 or
Exhibit A-2 hereto) specifying that the holder thereby intends to exercise the
Conversion Right and indicating the number of shares subject to this Warrant
which are being surrendered (referred to in Section 10.2(a) hereof as the
Converted Warrant Shares) in exercise of the Conversion Right. Such conversion
shall be effective upon receipt by the Company of this Warrant together with the
aforesaid written statement, or on such later date as is

                                      -8-

<PAGE>

specified therein (the "Conversion Date"), and, at the election of the holder
hereof, may be made contingent upon the closing of the sale of the Company's
Common Stock to the public in a public offering pursuant to a Registration
Statement under the Act (a "Public Offering"). Certificates for the shares
issuable upon exercise of the Conversion Right and, if applicable, a new warrant
evidencing the balance of the shares remaining subject to this Warrant, shall be
issued as of the Conversion Date and shall be delivered to the holder within
thirty (30) days following the Conversion Date.

         (c)  Determination of Fair Market Value.  For purposes of this Section
              ----------------------------------
10.2, "fair market value" of a share of Series Preferred (or Common Stock if the
Series Preferred has been automatically converted into Common Stock) as of a
particular date (the "Determination Date") shall mean:

              (i)       If the Conversion Right is exercised in connection with
and contingent upon a Public Offering, and if the Company's Registration
Statement relating to such Public Offering ("Registration Statement") has been
declared effective by the Securities and Exchange Commission, then the initial
"Price to Public" specified in the final prospectus with respect to such
offering.

              (ii)      If the Conversion Right is not exercised in connection
with and contingent upon a Public Offering, then as follows:

         (A)  If traded on a securities exchange, the fair market value of the
Common Stock shall be deemed to be the average of the closing prices of the
Common Stock on such exchange over the five trading days immediately prior to
the Determination Date, and the fair market value of the Series Preferred shall
be deemed to be such fair market value of the Common Stock multiplied by the
number of shares of Common Stock into which each share of Series Preferred is
then convertible;

         (B)  If traded on the Nasdaq Stock Market or other over-the-counter
system, the fair market value of the Common Stock shall be deemed to be the
average of the closing bid prices of the Common Stock over the five trading days
immediately prior to the Determination Date, and the fair market value of the
Series Preferred shall be deemed to be such fair market value of the Common
Stock multiplied by the number of shares of Common Stock into which each share
of Series Preferred is then convertible; and

         (C)  If there is no public market for the Common Stock, then fair
market value shall be as determined in good faith by the Board of Directors of
the Company upon a review of relevant factors.

     In making a determination under clauses (A) or (B) above, if on the
Determination Date, five trading days had not passed since the IPO, then the
fair market value of the Common Stock shall be the average closing prices or
closing bid prices, as applicable, for the shorter period beginning on and
including the date of the IPO and ending on the trading day prior to the
Determination Date (or if such period includes only one trading day the closing
price or closing bid price, as applicable, for such trading day). If closing
prices or closing bid prices are no longer reported by a securities exchange or
other trading system, the closing price or closing bid price shall be that which
is

                                      -9-

<PAGE>

reported by such securities exchange or other trading system at 4:00 p.m. New
York City time on the applicable trading day.

         10.3    Exercise Prior to Expiration. To the extent this Warrant is not
                 ----------------------------
previously exercised as to all of the Shares subject hereto, and if the fair
market value of one share of the Series Preferred is greater than the Warrant
Price then in effect, this Warrant shall be deemed automatically exercised
pursuant to Section 10.2 above (even if not surrendered) immediately before its
expiration. For purposes of such automatic exercise, the fair market value of
one share of the Series Preferred upon such expiration shall be determined
pursuant to Section 10.2(c). To the extent this Warrant or any portion thereof
is deemed automatically exercised pursuant to this Section 10.3, the Company
agrees to promptly notify the holder hereof of the number of Shares, if any, the
holder hereof is to receive by reason of such automatic exercise.

    11.  Representations and Warranties.  The Company represents and warrants to

                                     [Date]

GATX VENTURES, INC.
3687 Mt. Diablo Blvd., Suite 200
Lafayette, California 94549

Gentlemen:

     We have acted as counsel for [BORROWER) (the "Borrower") in connection with
(i) the execution of the Loan and Security Agreement of even date herewith (the
"Loan") between Borrower and GATX VENTURES ("Lender"), (ii) the issuance of a
warrant to purchase shares of Borrower's [Common] [Series _ Preferred] Stock
(the "Warrant") and (iii) the transactions contemplated thereby. This opinion is
being rendered to you pursuant to Section 8.01 of the Loan Agreement.
Capitalized terms not otherwise defined in this opinion have the meaning given
them in the Loan Agreement.

     In connection with this opinion and our representation, we have examined
originals, or copies certified or otherwise identified to our satisfaction, of
the following:

     (i)    The Loan Agreement;

     (ii)   The Warrant and exhibits thereto dated as of [Date], issued by
            Borrower to Lender;

     (iii)  The Restated [Certificate] [Articles] of Incorporation and the
            Bylaws of Borrower, each as in effect on the date hereof;

     (iv)   The certificate of an officer of Borrower as to certain factual
            matters ("Officer Certificate");

     (v)    Certificates issued by the Secretary of State of the State of dated
                       , 199 , [and the Secretary of State of the State of dated
                       , 199 ,] certifying the good standing of Borrower;

     (vi)   Such other documents, records, and certificates as we have deemed
            necessary or appropriate as a basis for the opinions hereafter
            expressed.

     The Loan Agreement and the Warrant are hereinafter referred to as the
"Transaction Documents."

     In such examinations we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals and the conformity to
originals of all documents submitted to us as certified, facsimile, telecopied
or photostatic copies thereof. As to certain

<PAGE>

matters of fact material to our opinion, we have relied upon the Officer
Certificate and upon your representations in the Transaction Documents.

     As used in this opinion, the expression "to the best of our knowledge,"
means the actual present knowledge or belief of those attorneys in our firm who
have or who are currently representing Borrower. We have not undertaken any
independent investigation to determine the existence or nonexistence of other
facts, and no reference as to our knowledge of the existence or nonexistence of
other facts should be drawn from the fact of this firm's representation of
Borrower in connection with the Transaction Documents.

     Based upon and subject to the foregoing and subject to the qualifications
contained herein, we are of the opinion that:

     (a)  Borrower is a corporation duly organized, validly existing and in good
          standing under the laws of the State of Delaware.

     (b)  Borrower has the requisite corporate power and authority to execute,
          deliver and perform the Transaction Documents and to issue the
          Warrant. All action on the part of Borrower, its directors and to
          shareholders necessary for the authorization, execution, delivery and
          performance of the Transaction Documents, has been taken. The
          Transaction Documents have been duly executed and delivered by an
          authorized officer of Borrower.

     (c)  The execution, delivery and performance of the Transaction Documents
          do not conflict with or violate any provision of Borrower's Restated
          Certificate [Articles] of Incorporation or Bylaws or of applicable law
          and, to the best of our knowledge, do not conflict with or constitute
          a default under any provision of any judgment, writ, decree, order or
          material agreement, indenture, or instrument to which Borrower is a
          party or by which it is bound.

     (d)  The Transaction Documents constitute legal, valid and binding
          obligations of Borrower, enforceable in accordance with their
          respective terms. Except for __________, to our knowledge, no filing
          need be made with any governmental authority with respect to the
          Transaction Documents in connection with an exemption from state usury
          laws or to connection with any other matter.

     (e)  [The Series Preferred Stock issuable upon exercise of the Warrant have
          been duly authorized and reserved for issuance upon such exercise, and
          when issued in accordance with the terns of the Warrant, will be duly
          authorized, validly issued, fully paid and non-assessable.] [The
          shares of Common Stock issuable upon conversion of the Series _
          Preferred Stock into which the Warrant is convertible, have been duly
          authorized and reserved and for issuance, when so issued in accordance
          with the terms of Borrowers Restated [Certificate] [Articles] of
          Incorporation, will be validly issued, fully paid and non-assessable.]

     (B)  Limitations imposed by general equitable principles upon the specific

          and upon the availability of injunctive relief or other equitable
          remedies.

     (C)  We express no opinion as to the enforceability of any choice of law
          provision in the documents.
