                          STOCK SUBSCRIPTION WARRANT

                                 June 4, 1999

          THIS CERTIFIES that SPRINT SPECTRUM L.P., a Delaware limited
partnership (the "Investor"), or its registered assigns, is entitled to
                  --------
subscribe for and purchase from NEOPOINT, INC., a California corporation (the
"Corporation"), 379,693 shares (the "Warrant Shares") of common stock of the
 -----------                         --------------
Corporation (the "Common Stock"), at the price (the "Warrant Price") of $4.00
                  ------------                       -------------
per share, at any time or from time to time during the period commencing on and
after January 1, 2000 and ending on the January 1, 2005 (the "Exercise Period"),
                                                              ---------------
on the terms and subject to the conditions hereof. The Investor and any
registered assigns thereof are referred to as the "Holder." The number of
Warrant Shares and the Warrant Price are subject to adjustment, as provided in
herein.

          This Warrant is issued pursuant to the CDMA PCS Subscriber Unit Supply
Agreement dated as of June 4, 1999 between Sprint Spectrum Equipment Company,
L.P., a Delaware limited partnership, and the Corporation.

     Section 1. Exercise of Warrant.
                -------------------

          (a)   The rights represented by this Warrant may be exercised (a
"Warrant Exercise") by the Holder, in whole or in part at any time during the
 ----------------
Exercise Period, but not as to any fractional share of Common Stock, by the
surrender of this Warrant, accompanied by a properly completed and executed
Notice of Exercise in the form attached hereto and payment of the Warrant Price
at the offices of the Corporation set forth in Section 8. At the option of the
Holder, the Warrant Price shall be payable:

               (i)  in cash or by certified or official bank check payable to
     the order of the Corporation; or

               (ii) by delivery of this Warrant to the Corporation for
     cancellation in accordance with the further provisions of this Section
     1(a)(ii). In exchange for the portion of this Warrant that is being
     exercised at such time, the Holder shall receive the number of shares of
     Common Stock determined by multiplying (A) the number of shares of Common
     Stock for which this Warrant is being exercised at such time by (B) a
     fraction, (1) the numerator of which shall be the difference between (x)
     current market price per share of Common Stock (as determined in good faith
     by the Corporation's
<PAGE>

     Board of Directors after giving affect to any applicable illiquidity and/or
     minority interest discounts) at such time and (y) the Warrant Price per
     share of Common Stock, and (2) the denominator of which shall be the
     current market price per share of Common Stock at such time (as determined
     in good faith by the Corporation's Board of Directors after giving affect
     to any applicable illiquidity and/or minority interest discounts). The
     Corporation shall issue a new warrant for the portion, if any, of this
     Warrant not being exercised as provided in Section 1(c).

          (b)  The closing of any Warrant Exercise shall take place at the
offices of the Corporation on the date specified in the Notice of Exercise (the
"Exercise Date"), which shall be within five days after the delivery of such
 -------------
Notice of Exercise. At such closing, (i) the Corporation shall issue and deliver
to the Holder or its designee a certificate or certificates for the Warrant
Shares to be issued upon such Warrant Exercise, registered in the name of the
Holder or such designee, and if such Warrant Exercise shall not have been for
all Warrant Shares, a new Warrant, registered in the name of the Holder, of like
tenor to this Warrant for the number of remaining Warrant Shares, and (ii) the
Holder shall deliver to the Corporation the aggregate Warrant Price.

          (c)  If this Warrant shall have been exercised only in part, the
Corporation shall, at the time of delivery of the certificate or certificates or
other evidence of ownership of the Common Stock, execute and deliver to the
Holder, without charge, a new warrant evidencing the rights of the Holder to
purchase the unpurchased Common Stock called for by this Warrant, which new
warrant shall in all other respects be identical to this Warrant.

     Section 2.  Record Date.
                 -----------

          The person in whose name any certificate for shares of Common Stock is
issued upon any Warrant Exercise or Warrant Exchange shall for all purposes be
deemed to have become the holder of record of such shares on the date on which
the Warrant was surrendered and payment of the Warrant Price and any applicable
tax was made, irrespective of the date of such certificate; provided, however,
                                                            --------  -------
that if the date of such surrender and payment is a date when the stock transfer
books of the Corporation are closed, such person shall be deemed to have become
the holder of such shares at the close of business on the next succeeding date
on which the stock transfer books are open.

     Section 3.  Reservation of Common Stock; Covenants as to Common Stock.
                 ---------------------------------------------------------

          The Corporation has duly reserved, and shall at all times duly
reserve, a sufficient number of shares of authorized Common Stock for issuance
upon exercise or exchange of this Warrant. Upon issuance, sale and delivery of
any Warrant Shares, such Warrant Shares shall be validly issued and outstanding,
fully paid and nonassessable, and free from all taxes, liens and charges with
respect to the issuance thereof, and shall not be subject to preemptive or any
similar rights of any person or entity. Without limiting the generality of the
foregoing, the Corporation shall take all such action as may be necessary to
ensure that the stated or par value per share of Common Stock is at all times
equal to or less than the Warrant Price then in effect. The Corporation
covenants and agrees that if any shares of capital stock to be reserved for the
purpose of the issuance of shares of Common Stock upon the exercise of this
Warrant require registration with or approval of any governmental authority
under any

                                      -2-
<PAGE>

Federal or state law before such shares may be validly issued or delivered upon
exercise, then the Corporation will in good faith and expeditiously as possible
endeavor to secure such registration or approval, as the case may be. If and so
long as the Common Stock issuable upon the exercise of this Warrant is listed on
any national securities exchange, the Corporation will, if permitted by the
rules of such exchange, list and keep listed on such exchange, upon official
notice of issuance, all shares of such capital stock.

     Section 4. Adjustment of Warrant Price.
                ---------------------------

          (a)   If, at any time during the Exercise Period, the number of
outstanding shares of Common Stock is (i) increased by a stock dividend payable
in shares of Common Stock or by a subdivision or split-up of shares of Common
Stock, or (ii) decreased by a combination of shares of Common Stock, then,
following the record date fixed for the determination of holders of Common Stock
entitled to receive the benefits of such stock dividend, subdivision, split-up,
or combination, as the case may be, the Warrant Price shall be adjusted to a new
amount equal to the product of (A) the Warrant Price in effect on such record
date and (B) the quotient obtained by dividing (x) the number of shares of
Common Stock outstanding on such record date (without giving effect to the event
referred to in the foregoing clause (i) or (ii)) by (y) the number of shares of
Common Stock which would be outstanding immediately after the event referred to
in the foregoing clause (i) or (ii), if such event had occurred immediately
following such record date.

          (b)   If, at any time during the Exercise Period, the Corporation
shall issue or be deemed to have issued (as provided below) shares of Common
Stock or any warrant or other securities exercisable for shares of Common Stock
without consideration or for a consideration per share less than the Warrant
Price in effect immediately prior to such issuance or deemed issuance, then such
Warrant Price shall be lowered, effective as of the date of such issuance, to a
price equal to the quotient obtained by dividing (i) an amount equal to the sum
of (A) the product of (x) the number of shares of Common Stock outstanding
immediately prior to such issuance or deemed issuance and (y) the then existing
Warrant Price, and (B) the total consideration received or deemed received by
the Corporation upon such issuance or deemed issuance, by (ii) the total number
of shares of Common Stock outstanding immediately after such issuance or deemed
issuance. For the purposes of any adjustment of the Warrant Price pursuant to
this paragraph, the following provisions shall be applicable:

                (i)   In the case of the issuance of Common Stock for cash, the
     consideration shall be deemed to be the amount of cash paid therefor
     without deducting therefrom any discounts, commissions or other expenses
     allowed, paid or incurred by the Corporation for any underwriting or
     otherwise in connection with such issuance.

                (ii)  In the case of the issuance of Common Stock for no
     consideration, the consideration shall be deemed to be $.01 per share.

                (iii) In the case of the issuance of Common Stock for a
     consideration in whole or in part other than cash, the consideration other
     than cash shall be deemed to be the fair market value thereof as determined
     by the Board of Directors of the Corporation, irrespective of any
     accounting treatment.

                                      -3-
<PAGE>

                (iv) In the case of the issuance of options to purchase or
     rights to subscribe for Common Stock, securities by their terms convertible
     into or exchangeable for Common Stock, or options to purchase or rights to
     subscribe for such convertible or exchangeable securities:

                    (A)  The shares of Common Stock deliverable upon exercise of
          such options to purchase, or rights to subscribe for, Common Stock
          shall be deemed to have been issued at the time such options or rights
          were issued and for a consideration equal to the consideration
          (determined in the manner provided in clauses (i) through (iii)
          above), if any, received by the Corporation upon the issuance of such
          options or rights plus the minimum purchase price provided in such
          options or rights for the Common Stock covered thereby.

                    (B)  The shares of Common Stock deliverable upon conversion
          of, or in exchange for, any such convertible or exchangeable
          securities or upon the exercise of options to purchase, or rights to
          subscribe for, such convertible or exchangeable securities and
          subsequent conversions or exchanges thereof shall be deemed to have
          been issued at the time such securities were issued or such options or
          rights were issued and for a consideration equal to the consideration
          received by the Corporation for any such securities and related
          options or rights (excluding any cash received on account of accrued
          interest or accrued dividends) plus the additional consideration, if
          any, to be received by the Corporation upon the conversion or exchange
          of such securities or the exercise of any related options or rights
          (the consideration in each case to be determined in the manner
          provided in clauses (i) through (iii) above).

                    (C)  Upon any change in the exercise price or number of
          shares of Common Stock deliverable upon exercise of any such options
          or rights of conversion of, or exchange for, such convertible or
          exchangeable securities (including any such change resulting from the
          termination of any such options, rights, or securities), other than a
          change resulting from the antidilution provisions thereof, the Warrant
          Price shall be readjusted to such Warrant Price as would have obtained
          had the adjustment made upon the issuance of such options, rights or
          securities not converted prior to such change been made upon the basis
          of such change.

                    (D)  No further adjustments of the Warrant Price shall be
          made upon the actual issuance of such Common Stock or of such
          convertible or exchangeable securities, upon exercise of such options
          or rights, or upon the actual issuance of such Common Stock upon
          conversion or exchange of such convertible or exchangeable securities.

               (v)  No adjustment shall be made to the Warrant Price for any
     issuance of Common Stock to employees, officers, directors or consultants
     pursuant to the Corporation's Board approved stock option plans.

          (c)  All calculations under this Section 4 shall be made to the
nearest one hundredths (1/100) of a cent.

                                      -4-
<PAGE>

          (d)  Whenever the Warrant Price shall be adjusted as provided above,
the Corporation shall deliver to the Holder a statement, signed by its chief
financial officer, showing in detail the facts requiring such adjustment and the
Warrant Price that shall be in effect after such adjustment.

     Section 5. Adjustment of Warrant Shares.
                ----------------------------

          (a)  Upon each adjustment of the Warrant Price as provided in Section
4, the Holder shall thereafter be entitled to subscribe for and purchase, at the
Warrant Price resulting from such adjustment, the number of Warrant Shares equal
to the product of (i) the number of Warrant Shares existing prior to such
adjustment and (ii) the quotient obtained by dividing (A) the Warrant Price
existing prior to such adjustment by (B) the new Warrant Price resulting from
such adjustment. No fractional shares of Common Stock shall be issued upon
exercise of this Warrant. Instead of any fractional shares of Common Stock which
would otherwise be issuable upon exercise of this Warrant, the Holder may deduct
from the aggregate Warrant Price an amount equal to the product of (i) the fair
market value of one share of Common Stock as determined in good faith by the
Holder and (ii) such fractional interest.

          (b)  Following any recapitalization, reorganization, reclassification,
consolidation, merger or the conveyance of all or substantially all of the
assets of the Corporation pursuant to which the holders of Common Stock are
entitled to receive (either directly or upon subsequent liquidation) stock,
securities or assets with respect to or in exchange for Common Stock (each, an
"Organic Change") during the Exercise Period, this Warrant shall represent the
 --------------
right to subscribe for and purchase the kind and number of shares of capital
stock or other securities or property which the Holder would have owned or have
been entitled to receive with respect to each Warrant Share had this Warrant
been exercised immediately prior to such Organic Change. The foregoing provision
shall similarly apply to successive Organic Changes.

     Section 6. Transfer, Division and Combination.
                ----------------------------------

          (a)  Subject to the restrictions on transfer set forth herein, this
Warrant and all rights hereunder are assignable and transferable, in whole or in
part, without the consent of the Corporation. Any transfer shall be effected by
the Holder in person or by duly authorized attorney by surrendering this
Warrant, properly endorsed, at the offices of the Corporation. Each taker and
holder of this Warrant, by taking or holding the same, consents and agrees that
this Warrant, when endorsed, in blank, shall be deemed negotiable, and, when so
endorsed, the holder hereof may be treated by the Corporation and all other
persons dealing with this Warrant as the absolute owner hereof for any purposes
and as the person entitled to exercise the rights represented by this Warrant,
or to the transfer hereof on the books of the Corporation, any notice to the
contrary notwithstanding; provided, however, that until such transfer is on such
                          --------  -------
books, the Corporation may treat the registered holder hereof as the owner
hereof for all purposes. Notwithstanding anything contained herein to the
contrary for the first two (2) years from and after the date hereof (and only
for such two (2) year period) the Investor and any subsequent Holder may not
assign, transfer or sell this Warrant or the Warrant Shares issuable hereunder
to any party other than a person or entity controlled by or under common control
with the ultimate corporate parent of the Investor.

                                      -5-
<PAGE>

          (b)  This Warrant may be exchanged for, or combined with, other
warrants upon presentation of this Warrant and any other warrants with which
this Warrant is to be combined to the Corporation, together with a written
notice specifying the denominations in which a new Warrant or Warrants are to be
issued, signed by the Holder. The Corporation shall execute and deliver a new
warrant or warrants to the Holder in exchange for the warrant or warrants to be
divided or combined in accordance with such notice.

     Section 7.  Right of First Refusal.
                 ----------------------

          (a)  Notice of Transfer. In the event that the Holder proposes to
               ------------------
sell, assign, pledge, encumber, transfer or otherwise dispose of ("Transfer")
the Warrant or any shares issued upon exercise of the Warrant (collectively, the
"Shares") during the third or fourth years from and after the date hereof to any
party other than a person or entity controlled by or under common control with
the ultimate corporate parent of the Holder, the Holder shall give the
Corporation written notice of its intention ("Transfer Notice"), describing the
offered Shares ("Offered Shares"), the identity of the prospective transferee,
the consideration and the material terms and conditions upon which the proposed
Transfer is to be made.

          (b)  Right of First Refusal. With respect to any proposed Transfer,
               ----------------------
the Corporation shall have an option to purchase all or none of the Offered
Shares (the "Right of First Refusal"). To exercise the Right of First Refusal,
the Corporation must notify the Holder in writing of its decision to exercise
such option before the expiration of the ten (10) business day period following
the delivery of the Transfer Notice to the Corporation. If the Corporation
elects to purchase the Offered Shares, it shall pay consideration for the
Offered Shares no less favorable in price and material terms and conditions than
are described in the Transfer Notice.

          (c)  Closing Procedures. If the Corporation exercises the Right to
               ------------------
First Refusal, the Corporation and the Holder shall consummate the sale of the
Offered Shares on the terms set forth in the Transfer Notice by the date ten
(10) business days after the delivery of the Transfer Notice to the Corporation.
If the Corporation fails to exercise in full the Right of First Refusal on a
timely basis, then the Holder may, conclude the Transfer on the terms and
conditions described in the Transfer Notice.

          (d)  Termination of Right. The Right of First Refusal shall terminate
               --------------------
at such time as public market exists for the Corporation's Common Stock (or any
other stock issued by the Corporation, or any successor, in exchange for the
Stock). For the purpose of this Agreement, a "public market" shall be deemed to
exist if (i) such stock is listed on a national securities exchange (as that
term is used in the Securities Exchange Act of 1934) or (ii) such stock is
traded on the over-the-counter market and prices therefore are published daily
on business days in a recognized financial journal.

          (e)  Legends. All certificates representing any Shares subject to the
               -------
provisions of this Warrant shall have endorsed thereon the following legends:

               (i)  "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A

               (ii)  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
     SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE

     MADE IN ACCORDANCE WITH RULE 144 UNDER THE ACT OR IS OTHERWISE EXEMPT FROM
     REGISTRATION."

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

          So long as this Warrant remains outstanding, the Corporation shall
maintain an office in the continental United States where the Warrant may be
presented for exercise, transfer, division or combination as provided in this
Warrant. Such office shall be at 4225 Executive Drive, Suite 600, La Jolla,
California 92037, unless and until the Corporation shall designate and maintain
some other office for such purposes and give notice thereof to the Holder.

     Section 9.  Lost, Stolen, Mutilated or Destroyed Warrant.
                 --------------------------------------------

          If this Warrant is lost, stolen, mutilated or destroyed, the
Corporation shall, on such terms as to indemnity or otherwise as it may in its
reasonable discretion impose (which shall, in the case of a mutilated Warrant,
include the surrender thereof), issue a new Warrant of like denomination and
tenor as the Warrant so lost, stolen, mutilated or destroyed.

     Section 10. Transfer Taxes; Expenses.
                 ------------------------

          The Corporation shall pay all transfer taxes, stamp duties, and
similar taxes or fees payable in connection with any exercise or exchange of
this Warrant.

     Section 11. Limitation of Liability.
                 -----------------------

          Except as otherwise provided herein, this Warrant does not entitle the
Holder to any voting rights or other rights of a shareholder of the Corporation.
No provision hereof, in the absence of affirmative action by the Holder to
purchase shares of the Common Stock, and no mere enumeration herein of the
rights or privileges of the Holder, shall give rise to any liability of the
Holder for the Warrant Price or as a shareholder of the Corporation, whether
such liability is asserted by the Corporation, by any creditor of the
Corporation or any other person.

issuance of the Shares upon exercise of this Warrant in accordance with the
terms hereof will not be inconsistent with the Articles of Incorporation, as the
same may be amended from time to time, or Bylaws, do not and will not contravene
any law, governmental rule or regulation, judgment or order applicable to the
Company, and do not and will not conflict with or contravene any provision of,
or constitute a material default under, any material indenture, mortgage,
contract or other instrument of which the Company is a party or by which it is
bound or require the consent or approval of, the giving of notice to, the
registration or filing with or the taking of any action in respect of or by, any
federal, state or local government authority or agency (other than such
consents, approvals, notices, actions, filings, etc., as have already been
obtained or made, as the case may be).

     4.   Adjustment of Warrant Price and Number of Warrant Shares. The number
          --------------------------------------------------------
of securities issuable 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)  Adjustment for Dividends in Stock. In case at any time or from
               ---------------------------------
time to time the holders of Series C Preferred Stock of the Company (or any
shares of stock or other securities at the time receivable upon the exercise of
this Warrant) shall have received or, on or after the record date fixed for the
determination of eligible stockholders, shall have become entitled to receive,
without payment therefor, other or additional stock of the Company by way of
dividend then, and in each case, the Holder of this Warrant shall, upon the
exercise hereof, be entitled to receive, in addition to the number of Shares
receivable thereupon, and without payment of any additional consideration
therefor, the amount of such other or additional stock of the Company which such
Holder would hold on the date of such exercise had it been the holder of record
of Shares on the date hereof and had thereafter, during the period from the date
hereof to and including the date of such exercise, retained such shares and/or
all other additional stock receivable by it as aforesaid during such period,
giving effect to all adjustments called for during such period by subparagraphs
(b) and (c) of this Paragraph 5.

          (b)  Adjustment for Reclassification or Reorganization. In case of any
               -------------------------------------------------
reclassification or change of the outstanding securities of the Company or of
any reorganization of the Company, then and in each such case the Holder of this
Warrant, upon the exercise hereof at any time after the consummation of such
reclassification, change, or reorganization, shall be entitled to receive, in
lieu of or in addition to the stock or other securities and property receivable
upon the exercise hereof prior to such consummation, the stock or other
securities to which such Holder would have been entitled upon such consummation
if such Holder had exercised this Warrant immediately prior thereto, all subject
to further adjustment as provided in subparagraphs (a) and (c); in each such
case, the terms of this Paragraph 5 shall be applicable to the shares of stock
or other securities and property receivable upon the exercise of this Warrant
after such consummation.

                                       3
<PAGE>

          (c)  Stock Splits and Reverse Stock Splits. If the Company shall
               -------------------------------------
subdivide its outstanding shares of Series C Preferred Stock into a greater
number of shares, the Warrant Price in effect immediately prior to such
subdivision shall thereby be proportionately reduced and the number of Shares
receivable upon exercise of this Warrant shall thereby be proportionately
increased; and, conversely, if the outstanding number of shares of Common Stock
shall be combined into a smaller number of shares, the Warrant Price in effect
immediately prior to such combination shall thereby be proportionately increased
and the number of Shares receivable upon exercise of the Warrant shall be
proportionately decreased.

     5.   Notices of Record Date, Etc. In the event of (a) any taking by the
          ---------------------------
Company of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend or
other distribution (the "Distribution"), (b) any capital reorganization or
reclassification of the stated capital of the Company or any consolidation or
merger of the Company with any other corporation or corporations (other than a
wholly-owned subsidiary), or the sale or distribution of all or substantially
all of the Company's property and assets (the "Reorganization Event"), or (c)
any proposed filing of a registration statement under the Act in connection with
a primary public offering of the Company's Common Stock (the "Registration
Event"), the Company will mail or cause to be mailed to the Holder a notice
specifying (i) the date of any such Distribution stating the amount and
character of such Distribution, (ii) the date on which any such Reorganization
Event or Registration Event is expected to become effective, and (iii) the time,
if any, that is to be fixed as to when the holders of record of the Company's
securities shall be entitled to exchange their shares of the Company's
securities for securities or other property deliverable upon such Reorganization
Event. Such notice shall be mailed at least thirty (30) days prior to the date
therein specified.

     6.   Compliance with Act; Transferability and Negotiability of Warrant;
          -----------------------------------------------------------------
Disposition of Shares.
---------------------

          (a)  Compliance with Act. The Holder, by acceptance hereof, agrees
               -------------------
that this Warrant and the Shares to be issued upon the exercise hereof are being
acquired solely for its own account and not as a nominee for any other party and
not with a view toward the resale or distribution thereof and that it will not
offer, sell or otherwise dispose of this Warrant or any Shares to be issued upon
the exercise hereof except under circumstances which will not result in a
violation of the Act. Upon the exercise of this Warrant, the Holder shall
confirm in writing, in a form satisfactory to the Company, that the Shares so
issued are being acquired solely for its own account and not as a nominee for
any other party and not with a view toward resale or distribution thereof in
violation of the Act. This Warrant and the Shares to be issued upon the exercise
hereof (unless registered under the Act and unless, in the case of the Shares,
such Shares may thereupon be sold pursuant to Commission Rule 144(k)) shall be
imprinted with a legend in substantially the following form:

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED,
          ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION
          STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN
          ACCORDANCE WITH

                                       4
<PAGE>

          RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL
          FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE
          COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION
          IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS
          OF SUCH ACT.

     In addition, this Warrant and the Shares to be issued upon the exercise
hereof shall bear any legends required by the securities laws of any applicable
states.

          (b)  Transferability and Negotiability of Warrant. This Warrant may
               --------------------------------------------
not be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and the
transferee (including the delivery of investment representation letters and
legal opinions reasonably satisfactory to the Company, if requested by the
Company). Subject to the provisions of this Warrant with respect to compliance
with the Act, title to this Warrant may be transferred by endorsement and
delivery in the same manner as a negotiable instrument transferable by
endorsement and delivery; provided, however, that prior to the Company's initial
public offering neither this Warrant nor the Shares purchasable with this
Warrant may be transferred to any entity or person which the Company reasonably
determines to be an actual competitor of the Company. The Company shall act
promptly to record transfers of this Warrant on its books, but the Company may
treat the registered holder of this Warrant as the absolute owner of this
Warrant for all purposes, notwithstanding any notice to the contrary.

          (c)  Disposition of Warrant Shares. With respect to any offer, sale,
               -----------------------------
transfer or other disposition of any Shares acquired pursuant to the exercise of
this Warrant prior to registration of such Shares, the Holder and each
subsequent holder of this Warrant agrees to give written notice to the Company
prior thereto, describing briefly the manner thereof, together with a written
opinion of legal counsel for such holder, reasonably satisfactory to the Company
and its legal counsel, if requested by the Company, to the effect that such
offer, sale or other disposition may be effected without registration or
qualification (under the Act or any other federal or state securities laws) of
such Shares and indicating whether or not under the Act, certificates for such
Shares to be sold or otherwise disposed of require any restrictive legend as to
the applicable restrictions on transferability in order to ensure compliance
with the Act. Promptly upon receiving such written notice and reasonably
satisfactory opinion, if so requested, the Company, as promptly as practicable,
shall notify such Holder that such Holder may sell or otherwise dispose of such
Shares, all in accordance with the terms of the notice delivered to the Company.
If a determination has been made pursuant to this subsection (c) that the
opinion of legal counsel for the holder is not reasonably satisfactory to the
Company and its legal counsel, the Company shall so notify the holder promptly
after such determination has been made. Notwithstanding the foregoing, such
Shares may be offered, sold or otherwise disposed of in accordance with Rule
144, 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 have been satisfied. Each certificate representing the
Shares thus transferred (except a transfer pursuant to Rule 144(k) or an
effective registration statement) shall bear a restrictive legend as to the
applicable restrictions on transferability in order to ensure compliance with
the Act, unless in the aforesaid opinion of legal counsel for the holder, such
legend is not required in

                                       5
<PAGE>

order to ensure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

     7.   Rights of Shareholders. No Holder shall be entitled to vote or receive
          ----------------------
dividends or be deemed the holder of Warrant Shares or any other securities of
the Company which may at any time be issuable on the exercise of this Warrant
for any purpose, nor shall anything contained herein be construed to confer upon
the Holder, 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 give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, consolidation, merger, transfer of assets or
otherwise) or to receive notice of meetings, or to receive dividends or
subscription rights or otherwise until this Warrant shall have been exercised
and the Warrant Shares issuable upon exercise hereof shall have become
deliverable, as provided herein.

     8.   Replacement of Warrants. On receipt of evidence reasonably
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     9.   Exchange of Warrant. Subject to the other provisions of this Warrant,
          -------------------
on surrender of this Warrant for exchange, properly endorsed and subject to the
provisions of this Warrant with respect to compliance with the Act, the Company
at its expense shall issue to or on the order of the Holder a new warrant or
warrants of like tenor, in the name of the Holder or as the Holder (on payment
by the Holder of any applicable transfer taxes) may direct, for the number of
Shares issuable upon exercise thereof.

     10.  Notices. All notices and other communications from the Company to the
          -------
Holder, or vice versa, shall be deemed delivered and effective when given
personally or three days after being mailed by first-class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company or the Holder, as the case may be, in writing by the Company or such
Holder from time to time.

     11.  Waiver. This Warrant and any term hereof may be changed, waived,
          ------
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

     12.  Governing Law. This Warrant shall be governed by and construed in
          -------------
accordance with the laws of the State of California, as such laws are applied to
agreements entered into in California and to be performed solely by California
residents.

     13.  Titles and Subtitles; Forms of Pronouns. The titles of the Sections
          ---------------------------------------
and Subsections of this Warrant are for convenience only and are not to be
considered in construing this Warrant. All pronouns used in this Warrant shall
be deemed to include masculine, feminine and neuter forms.
