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 TO AN AFFILIATE OF THE ORIGINAL HOLDER OR PURSUANT TO RULE 144(K) OR AN
OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION AND ITS COUNSEL,

                            WARRANT TO PURCHASE STOCK

              Corporation: WIRELESS, INC., a CALIFORNIA corporation
                         Number of Shares: 37,500 SHARES
                          Class of Stock: COMMON STOCK
                     Initial Exercise Price: $4.00 per share
                            Issue Date: JUNE 1, 2000
                          Expiration Date: JUNE 1, 2005

     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 nonassessable 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.

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

<PAGE>

traded in a public market, the Board of Directors of the Company shall determine
fair market value in its reasonable good faith judgment.

          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.

          1.6 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.

          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,t
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. [RESERVED]

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

                                       2
<PAGE>

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. 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.

          2.3 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.

          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.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

          3.1 REPRESENTATIONS AND WARRANTIES. The Company hereby represents and

purchase right represented by this Warrant, and all securities, if any, issuable

Company's quarterly, unaudited financial statements.

                            Anti-Dilution Provisions

     In the event of the issuance (a "Diluting Issuance") by the Company, after
the Issue Date of the Warrant, of securities at a price per share less than the
Warrant Price, then the number of shares of common stock issuable upon
conversion of the Shares, or if the Shares are common stock, the number of
Shares issuable upon exercise of the Warrant, shall be adjusted as a result of
Diluting Issuances in accordance with the Holder's standard form of
Anti-Dilution Agreement in effect on the Issue Date (the "Anti-Dilution
Agreement"), PROVIDED it is understood and agreed by the Holder that upon the
closing of the Company's underwritten initial public offering of its common
stock the Anti-Dilution Agreement shall no longer be deemed effective and shall
be considered terminated and of no further force or effect.

                               REGISTRATION RIGHTS

     The Company shall enter into the Holder's form of registration rights
agreement in connection herewith until such time that the Seventh Amended and

writing to the Holder, including the specific terms and provisions addressed in

the Holder, shall remain in its original form); at such time the Holder agrees
to enter into the Rights Agreement.

     The Company agrees that no amendments will be made to the Agreement which
would have an disproportionately adverse impact on Holder's registration rights
thereunder compared to the other parties thereto, without the consent of Holder.

          NOW, THEREFORE, in consideration of the mutual promises, covenants and

<PAGE>

          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-1
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-1, 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

                    (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:

                                       2
<PAGE>

               (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 to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

               (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 other document
(including any related registration statement, notification or the like)
incident to any such registration, qualification or compliance, or based on any
omission (or

                                       3
<PAGE>

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,
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.

                                       4
<PAGE>

               (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

                                       5
<PAGE>

the Company, and such other reports and documents so 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 Securities, the
obligations of the Company and the rights of the Holders of the 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
or any provision hereof may be changed, waived, discharged or terminated only by
a statement in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought, except to the extent
provided in this subsection 2.1.

          2.2 GOVERNING LAW. This Agreement shall be governed in all respects by
the laws of the State of California as such laws are applied to agreements
between California residents entered into and to be performed entirely within
California.

          2.3 SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.

          2.4 ENTIRE AGREEMENT. Except as set forth below, this Agreement and
the other documents delivered pursuant hereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects
hereof and thereof.

          2.6 SEVERABILITY. In case any provision of this Agreement shall be
invalid, illegal, or unenforceable, the validity, legality and enforceability of
the remaining provisions of this Agreement or any provision of the other
Agreement s shall not in any way be affected or impaired thereby.

          2.8 COUNTERPARTS. This Agreement may be executed in any number of

                             ANTIDILUTION AGREEMENT

          THIS ANTIDILUTION AGREEMENT is entered into as of June 1, 2000, by and
between SILICON VALLEY BANK ("Purchaser") and WIRELESS, INC.

                                    RECITALS

     A. Concurrently with the execution of this Antidilution 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 Antidilution Agreement, the Purchaser and the Company desire to
set forth the adjustment in the number of Shares issuable upon exercise of the
Warrant as a result of a Diluting Issuance (as defined in Exhibit A to the
Warrant).

     C. Capitalized terms used herein shall have the same meaning as set forth
in the Warrant.

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

          1. DEFINITIONS. As used in this Antidilution Agreement, the following
terms have the following respective meanings:

               (a) "Option" means any right, option, or warrant to subscribe
for, purchase, or otherwise acquire common stock or Convertible Securities.

               (b) "Convertible Securities" means any evidences of indebtedness,
shares of stock, or other securities directly or indirectly convertible into or
exchangeable for common stock.

               (c) "Issue" means to grant, issue, sell, assume, or fix a record
date for determining persons entitled to receive, any security (including
Options), whichever of the foregoing is the first to occur.

               (d) "Additional Common Shares" means all common stock (including
reissued shares) issued (or deemed to be issued pursuant to Section 2) after the
date of the Warrant. Additional Common Shares does not include, however, any
common stock issued in a transaction described in Sections 2.1 and 2.2 of the
Warrant; any common stock Issued upon conversion of preferred stock outstanding
on the date of the Warrant; the Shares; or common stock Issued as incentive or
in a nonfinancing transaction to employees, officers, directors, or consultants
to the Company.

<PAGE>

               (e) The shares of common stock ultimately Issuable upon exercise
of an Option (including the shares of common stock ultimately Issuable upon
conversion or exercise of a Convertible Security Issuable pursuant to an Option)
are deemed to be Issued when the Option is Issued. The shares of common stock
ultimately Issuable upon conversion or exercise of a Convertible Security (other
than a Convertible Security Issued pursuant to an Option) shall be deemed Issued
upon Issuance of the Convertible Security.

          2. DEEMED ISSUANCE OF ADDITIONAL COMMON SHARES. The shares of common
stock ultimately Issuable upon exercise of an Option (including the shares of
common stock ultimately Issuable upon conversion or exercise of a Convertible
Security Issuable pursuant to an Option) are deemed to be Issued when the Option
is Issued. The shares of common stock ultimately Issuable upon conversion or
exercise of a Convertible Security (other than a Convertible Security Issued
pursuant to an Option) shall be deemed Issued upon Issuance of the Convertible
Security. The maximum amount of common stock Issuable is determined without
regard to any future adjustments permitted under the instrument creating the
Options or Convertible Securities.

          3. ADJUSTMENT OF WARRANT PRICE FOR DILUTING ISSUANCES.

               3.1 WEIGHTED AVERAGE ADJUSTMENT. If the Company issues Additional
Common Shares after the date of the Warrant and the consideration per Additional
Common Share (determined pursuant to Section 9) is less than the Warrant Price
in effect immediately before such Issue, the Warrant Price shall be reduced,
concurrently with such Issue, to a price (calculated to the nearest hundredth of
a cent) determined by multiplying the Warrant Price by a fraction:

                    (a) the numerator of which is the amount of such common
stock outstanding immediately before such Issue plus the amount of common stock
that the aggregate consideration received by the Company for the Additional
Common Shares would purchase at the Warrant Price in effect immediately before
such Issue, and

                    (b) the denominator of which is the amount of common stock
outstanding immediately before such Issue plus the number of such Additional
Common Shares.

               3.2 ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the
Warrant Price, the number of Shares issuable upon exercise of the Warrant shall
be increased to equal the quotient obtained by dividing (a) the product
resulting from multiplying (i) the number of Shares issuable upon exercise of
the Warrant and (ii) the Warrant Price, in each case as in effect immediately
before such adjustment, by (b) the adjusted Warrant Price.

               3.3 SECURITIES DEEMED OUTSTANDING. For the purpose of this
Section 3, all securities issuable upon exercise of any outstanding Convertible
Securities or Options, warrants, or other rights to acquire securities of the
Company shall be deemed to be outstanding.

                                       2
<PAGE>

          4. NO ADJUSTMENT FOR ISSUANCES FOLLOWING DEEMED ISSUANCES. No
adjustment to the Warrant Price shall be made upon the exercise of Options or
conversion of Convertible Securities.

          5. ADJUSTMENT FOLLOWING CHANGES IN TERMS OF OPTIONS OR CONVERTIBLE
SECURITIES. If the consideration payable to, or the amount of common stock
Issuable by, the Company increases or decreases, respectively, pursuant to the
terms of any outstanding Options or Convertible Securities, the Warrant Price
shall be recomputed to reflect such increase or decrease. The recomputation
shall be made as of the time of the Issuance of the Options or Convertible
Securities. Any changes in the Warrant Price that occurred after such Issuance
because other Additional Common Shares were Issued or deemed Issued shall also
be recomputed.

          6. RECOMPUTATION UPON EXPIRATION OF OPTIONS OR CONVERTIBLE SECURITIES.
The Warrant Price computed upon the original Issue of any Options or Convertible
Securities, and any subsequent adjustments based thereon, shall be recomputed
when any Options or rights of conversion under Convertible Securities expire
without having been exercised. In the case of Convertible Securities or Options
for common stock, the Warrant Price shall be recomputed as if the only
Additional Common Shares Issued were the shares of common stock actually Issued
upon the exercise of such securities, if any, and as if the only consideration
received therefor was the consideration actually received upon the Issue,
exercise or conversion of the Options or Convertible Securities. In the case of
Options for Convertible Securities, the Warrant Price shall be recomputed as if
the only Convertible Securities Issued were the Convertible Securities actually
Issued upon the exercise thereof, if any, and as if the only consideration
received therefor was the consideration actually received by the Company
(determined pursuant to Section 9), if any, upon the Issue of the Options for
the Convertible Securities.

          7. LIMIT ON READJUSTMENTS. No readjustment of the Warrant Price
pursuant to Sections 5 or 6 shall increase the Warrant Price more than the
amount of any decrease made in respect of the Issue of any Options or
Convertible Securities.

          8. 30 DAY OPTIONS. In the case of any Options that expire by their
terms not more than 30 days after the date of Issue thereof, no adjustment of
the Warrant Price shall be made until the expiration or exercise of all such
Options.

          9. COMPUTATION OF CONSIDERATION. The consideration received by the
Company for the Issue of any Additional Common Shares shall be computed as
follows:

               (a) CASH shall be valued at the amount of cash received by the
Corporation, excluding amounts paid or payable for accrued interest or accrued
dividends.

               (b) PROPERTY. Property other than cash shall be computed at the
fair market value thereof at the time of the Issue as determined in good faith
by the Board of Directors of the Company.

                                       3
<PAGE>

               (c) MIXED CONSIDERATION. The consideration for Additional Common
Shares Issued together with other property of the Company for consideration that
covers both shall be determined in good faith by the Board of Directors.

               (d) OPTIONS AND CONVERTIBLE SECURITIES. The consideration per
Additional Common Share for Options and Convertible Securities shall be
determined by dividing:

                    (i) the total amount, if any, received or receivable by the
Company for the Issue of the Options or Convertible Securities, plus the minimum
amount of additional consideration (as set forth in the instruments relating
thereto, without regard to any provision contained therein for a subsequent
adjustment of such consideration) payable to the Company upon exercise of the
Options or conversion of the Convertible Securities, by

                    (ii) the maximum amount of common stock (as set forth in the
instruments relating thereto, without regard to any provision contained therein
for a subsequent adjustment of such number) ultimately Issuable upon the
exercise of such Options or the conversion of such Convertible Securities.

          10. GENERAL.

               10.1 GOVERNING LAW. This Antidilution Agreement shall be governed
in all respects by the laws of the State of California as such laws are applied
to agreements between California residents entered into and to be performed
entirely within California.

               10.2 SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

               10.3 ENTIRE AGREEMENT. Except as set forth below, this
Antidilution Agreement and the other documents delivered pursuant hereto
constitute the full and entire understanding and agreement between the parties

               10.4 NOTICES, ETC. All notices and other communications required

such other address as Purchaser shall have furnished to the Company in writing,
or (b) if to the Company, at the Company's address set forth below, or at such

Agreement shall be invalid, illegal, or unenforceable, the validity, legality
and enforceability of the remaining provisions of this Antidilution Agreement
shall not in any way be affected or impaired thereby.

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

                                   Receivables (less than 90 days from date of
                                   invoice as of such month end date), of not
                                   less than $4,000,000 at all times."

     3. COVENANT REGARDING IPO. Borrower shall consummate an initial public
offering of its common stock, yielding at least $50,000,000 in net proceeds to
the Borrower, no later than November 30, 2000, and the Borrower's failure to
accomplish the foregoing shall constitute an Event of Default under the Loan
Agreement.

     4. LIMITED WAIVER. Silicon hereby agrees to waive the existing Events of
Default arising from the Borrower's failure to comply with the "Tangible Net
Worth" financial covenant set forth in the Schedule to Loan Agreement for the
periods ending March 31, 2000 through June 30, 2000. Nothing herein is intended
to mean or imply that Silicon agrees or will agree to waive any subsequent
Events of Default nor does the foregoing waiver act to modify any term of
provision of the Loan Agreement, other than as specifically set forth above and
otherwise as set forth in this Agreement.

     5. FEE. Borrower shall pay to Silicon a fee of $10,000 in connection with
this Amendment. Further, when and if an Event of Default arises under the Loan
Agreement after the date hereof and during such time that any monetary
Obligations are then outstanding, then Borrower shall pay to Silicon an
additional fee of $25,000. All of such foregoing fees are in addition to
interest and to all other amounts payable under the Loan Agreement and are not
refundable.

     6. REPRESENTATIONS TRUE. Borrower represents and warrants to Silicon that
all representations and warranties set forth in the Loan Agreement, as amended
hereby, are true and correct.

     7. GENERAL PROVISIONS. This Amendment, the Loan Agreement, any prior
written amendments to the Loan Agreement signed by Silicon and Borrower, and the
other written documents and agreements between Silicon and Borrower set forth in
full all of the representations and agreements of the parties with respect to
the subject matter hereof and supersede all prior and contemporaneous
discussions, representations, agreements and understandings between the parties
with respect to the subject hereof. Except as herein expressly amended, all of
the terms and provisions of the Loan Agreement, and all other documents and
agreements between Silicon and Borrower shall continue in full force and effect
and the same are hereby ratified and confirmed.
