THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

                            WARRANT TO PURCHASE STOCK

Corporation: Wireless, Inc., a California corporation
Number of Shares: 4% Warrant Coverage
Class of Stock: Series D Preferred
Initial Exercise Price: The price given at the close of the Series D Preferred
offering.
Issue Date: October 16, 1998
Expiration Date: October 16, 2003

         THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase the number of fully paid and nonasssessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth in this Warrant. For purposes of
determining the Number of Shares, Warrant Coverage shall be defined as
$1,500,000.00 divided by the Initial Exercise Price multiplied by 4%.

ARTICLE 1. EXERCISE.

            1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

            1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares
shall be determined pursuant to Section 1.4.

            1.3 INTENTIONALLY OMITTED.

            1.4 FAIR MARKET VALUE. If the Shares are traded in a public
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not traded in a public
market, the Board of Directors of the Company shall determine fair market value
in its reasonable good faith judgment. The foregoing notwithstanding, if Holder
advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be
paid by the Company. In all other circumstances, such fees and expenses shall be
paid by Holder.

            1.5 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after
Holder exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

                                       1

<PAGE>

            1.6 REPLACEMENT OF WARRANTIES. 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.

            1.7 REPURCHASE ON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

                1.7.1.   "ACQUISITION".  For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

                1.7.2.   ASSUMPTION OF WARRANT.  Upon the closing of any
Acquisition the successor entity shall assume the obligations of this Warrant,
and this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition and subsequent closing. The Warrant Price shall
be adjusted accordingly.

                1.7.3.   PURCHASE  RIGHT.  Notwithstanding  the  foregoing,  at
the election of Holder, the Company shall purchase the unexercised portion of
this Warrant for cash upon the closing of any Acquisition for an amount equal to
(a) the fair market value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

            2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or pays a
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, subdivides the
outstanding common stock into a greater amount of common stock, or, if the
Shares are securities other than common stock, subdivides the Shares in a
transaction that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive, without cost to Holder, the total number and kind of securities
to which Holder would have been entitled had Holder owned the Shares of record
as of the date the dividend or subdivision occurred.

            2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock. The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property. The new Warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property
issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitutions,
or other events.

                                       2
<PAGE>

            2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares
are combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased.

            2.4 ADJUSTMENTS FOR DILUTING ISSUANCES. The Warrant Price and
the number of Shares issuable upon exercise of this Warrant or, if the Shares
are Preferred Stock, the number of shares of common stock issuable upon
conversion of the Shares, shall be subject to adjustment, from time to time in
the manner set forth on Exhibit A in the event of Diluting Issuances (as defined
on Exhibit A).

            2.5 NO IMPAIRMENT. The Company shall not, by amendment of its
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment. If the Company
takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares Issuable upon
exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

            2.6 FRACTIONAL SHARES. No fractional Shares shall be issuable
upon exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder amount computed by
multiplying the fractional interest by the fair market value of a full Share.

            2.7 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.

                          REGISTRATION RIGHTS AGREEMENT

                                    RECITALS

         A. Concurrently with the execution of this Agreement, the Purchaser is
purchasing from the Company a Warrant to Purchase Stock (the "Warrant") pursuant
to which Purchaser has the right to acquire from the Company the Shares (as
defined in the Warrant).

         B. By this  Agreement,  the Purchaser and the Company desire to set
forth the  registration  rights of the Shares all as provided herein.

            NOW, THEREFORE, in consideration of the mutual promises,
covenants and conditions hereinafter set forth, the parties hereto mutually
agree as follows:

         1. REGISTRATION RIGHTS. The Company covenants and agrees as follows:

            1.1   DEFINITIONS. For purposes of this Section 1:

                  (a)   The  term  "register,"  "registered,"  and
"registration" refer to a registration effected by preparing and filing a
registration statement or similar document in compliance with the Securities Act
of 1933, as amended (the "Securities Act"), and the declaration or ordering of
effectiveness of such registration statement or document;

                  (b)   The term  "Registrable  Securities"  means (i) the
Shares (if Common Stock) or all shares of Common Stock of the Company issuable
or issued upon conversion of the Shares and (ii) any Common Stock of the Company
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued as) a dividend or other distribution with respect
to, or in exchange for or in replacement of, any stock referred to in (i).

                  (c)    The terms "Holder" or "Holders" means the Purchaser
or qualifying transferees under subsection 1.8 thereof who hold Registrable
Securities.

                  (d)    The term "SEC" means the Securities and Exchange
Commission.

            1.2   COMPANY REGISTRATION.

                  (a)    REGISTRATION.  If at any time or from time to time,
the Company shall  determine to register any of its securities, for its own
account or the account of any of its shareholders, other than a registration on
Form S-l or S-8 relating solely to employee stock option or purchase plans, or
a registration on Form S-4 relating solely to an SEC Rule 145 transaction, or
a registration on any other form (other than Form S-l, S-2, S-3 or S-18, or
their successor forms) or any successor to such forms, which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the
Company will:

                          (i)   promptly  give to each Holder  written  notice
thereof (which shall include a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable blue sky or
other state securities laws); and
<PAGE>

                          (ii)  include in such registration (and  compliance),
and in any underwriting involved therein, all the Registrable Securities
specified in a written request or requests, made within 30 days after receipt of
such written notice from the Company, by any Holder or Holders, except as set
forth in subsection 1.2(b) below.

                    (b)   UNDERWRITING.  If the  registration  of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to subsection 1.2(a)(i). In such event the right of any
Holder to registration pursuant to this subsection 1.2 shall be conditioned upon
such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other shareholders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company.

            1.3     EXPENSES OF REGISTRATION. All expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Section 1 including without limitation, all registration, filing and
qualification fees, printing expenses, fees and disbursements of counsel for the
Company and expenses of any special audits incidental to or required by such
registration, shall be borne by the Company except the Company shall not be
required to pay underwriters fees, discounts or commissions relating to
Registrable Securities. All expenses of any registered offering not otherwise
borne by the Company shall be borne pro rata among the Holders participating in
the offering and the Company.

            1.4     REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this
Registration Rights Agreement, the Company will keep each Holder participating
therein advised in writing as to the initiation of each registration,
qualification and compliance and as to the completion thereof. Except as
otherwise provided in subsection 1.3, at its expense the Company will:

                    (a)   Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for up to 120 days.

                    (b)   Prepare and file with the SEC such  amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                    (c)   Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                    (d)   Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

<PAGE>

                    (e)   In the event of any underwritten  public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement

                    (f)   Notify each Holder of Registrable  Securities  covered
by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act or the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

            1.5     INDEMNIFICATION.

                    (a) The Company will indemnify each Holder of Registrable
Securities and each of its officers, directors and partners, and each person
controlling such Holder, with respect to which such registration, qualification
or compliance has been effected pursuant to this Rights Agreement, and each
underwriter, if any, and each person who controls any underwriter of the
Registrable Securities held by or issuable to such Holder, against all claims,
losses, expenses, damages and liabilities (or actions in respect thereto)
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any prospectus, offering circular or offer document
(including any related registration statement, notification or the like)
incident to any such registration, qualification or compliance, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statement therein not misleading, or any
violation or alleged violation by the Company of the Securities Act, the
Securities Exchange Act of 1934, as amended, ("Exchange Act") or any state
securities law applicable to the Company or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any such state law and relating to
action or inaction required of the Company in connection with any such
registration, qualification of compliance, and will reimburse each such Holder.
each of its officers, directors and partners, and each person controlling such
Holder, each such underwriter and each person who controls any such underwriter,
within a reasonable amount of time after incurred for any reasonable legal and
any other expenses incurred in connection with investigating, defending or
settling any such claim, loss, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 1.5(a) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability, or
action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld); and provided further, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage or liability arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company by an
instrument duly executed by such Holder or underwriter specifically for use
therein.

                    (b)   Each Holder will, if Registrable  Securities held by
or issuable to such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and partners and each person
controlling such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company, such Holders, such directors,
officers, partners, persons or underwriters for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, in each case to the extent,
but only to the extent, that such untrue statement (or alleged untrue statement)
or omission (or alleged omission) is made in such registration statement,

                                       3
<PAGE>

prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder specifically for use therein; provided, however,
that the indemnity agreement contained in this subsection 1.5(b) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability or
action if such settlement is effected without the consent of the Holder, (which
consent shall not be unreasonably withheld); and provided further, that the
total amount for which any Holder shall be liable under this subsection 1.5(b)
shall not in any event exceed the aggregate proceeds received by such Holder
from the sale of Registrable Securities held by such Holder in such
registration.

                    (c)   Each party entitled to  indemnification  under this
subsection 1.5 (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
indemnifying Party of its obligations hereunder, unless such failure resulted in
prejudice to the Indemnifying Party; and provided further, that an Indemnified
Party (together with all other Indemnified Parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the Indemnifying Party, if
representation of such indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between such indemnified Party and any other party represented by such
counsel in such proceeding. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation.

            1.6     INFORMATION BY HOLDER. Any Holder or Holders of
Registrable Securities included in any registration shall promptly furnish to
the Company such information regarding such Holder or Holders and the
distribution proposed by such Holder or Holders as the Company may request in
writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

            1.7     RULE 144 REPORTING. With a view to making available to
Holders the benefits of certain rules and regulations of the SEC which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees at all times to:

                    (a)   make and keep public information  available,  as those
terms are understood and defined in SEC Rule 144, after 90 days after the
effective date of the first registration filed by the Company for an offering of
its securities to the general public;

                    (b)   file with the SEC in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements); and

                    (c)   so long as a Holder owns any Registrable  Securities,
to furnish to such Holder forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after 90 days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Exchange Act (at any time after it
has become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
so

                                       4
<PAGE>

filed by the Company as the Holder may reasonably request in complying with any
rule or regulation of the SEC allowing the Holder to sell any such securities
without registration.

            1.8     TRANSFER OF REGISTRATION RIGHTS. Holders' rights to cause
the Company to register their securities and keep information available, granted
to them by the Company under subsections 1.2 and 1.7 may be assigned to a
transferee or assignee of a Holder's Registrable Securities not sold to the
public, provided, that the Company is given written notice by such Holder at the
time of or within a reasonable time after said transfer, stating the name and
address of said transferee or assignee and identifying the securities with
respect to which such registration rights are being assigned. The Company may
prohibit the transfer of any Holders' rights under this subsection 1.8 to any
proposed transferee or assignee who the Company reasonably believes is a
competitor of the Company.

         2.     GENERAL.

            2.1     WAIVERS AND AMENDMENTS. With the written consent of the
record or beneficial holders of at least a majority of the Registrable

Registrable Securities under this agreement may be waived (either generally or
in a particular instance, either retroactively or prospectively, and either for
a specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of its Board of Directors, may enter into
a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement;
provided, however, that no such modification, amendment or waiver shall reduce
the aforesaid percentage of Registrable Securities without the consent of all of
the Holders of the Registrable Securities. Upon the effectuation of each such
waiver, consent, agreement of amendment or modification, the Company shall
promptly give written notice thereof to the record holders of the Registrable
Securities who have not previously consented thereto in writing. This Agreement

change, waiver, discharge or termination is sought, except to the extent
provided in this subsection 2. 1.

respects by the laws of the State of California as such laws are applied to

enforceability of the remaining provisions of this Agreement or any provision of
