     THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT
     BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE WARRANT
     AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF MAY NOT BE SOLD, OFFERED

Warrant No. W-[  ]

                                 WIRELESS, INC.

                   WARRANT TO PURCHASE SHARES OF COMMON STOCK

                  This Warrant is issued to __________________  ("Holder") by
Wireless, Inc., a California corporation (the "Company"), as of the date set
forth beside the Company's signature below.

                  1. PURCHASE OF SHARES. Subject to the terms and conditions
hereinafter set forth, Holder is entitled, upon surrender of this Warrant at the
principal office of the Company (or at such other place as the Company shall
notify Holder in writing), to purchase from the Company up to 50,000 shares (the
"Shares") of common stock of the Company (the "Common Stock"), at an exercise
price of $2.50 per share (the "Exercise Price"). The Shares and the Exercise
Price shall be subject to adjustment as set forth in Section 7 hereof.

                  2.  EXERCISE PERIOD. This Warrant shall be exercisable
for a period (the "Exercise Period") of 36 months from the date hereof;
PROVIDED, however, that in the event of the earlier closing of (a) the issuance
and sale of shares of the Common Stock in the Company's first underwritten
public offering (the "IPO") pursuant to an effective registration statement
under the Securities Act of 1933, as amended (the "Act"), (b) a sale of all or
substantially all the assets of the Company, or (c) a merger or reorganization
of the Company into or consolidation with any other entity (excluding a
reorganization or merger, the sole purpose of which is to change the
jurisdiction of incorporation of the Company) in which shares representing a
majority of the Company's voting power immediately prior to the closing of such
merger or reorganization are transferred, this Warrant shall, upon the
consummation of such event, no longer be exercisable and become null and void.
In the event of a proposed transaction of the kind described above, the Company
shall notify Holder in writing at least fifteen (15) days prior to the
consummation of such event or transaction.

                  3.  METHOD OF EXERCISE. While this Warrant remains
outstanding and exercisable during the Exercise Period, Holder may exercise, in
whole or in part, the purchase rights evidenced hereby. Such exercise shall be
effected by: (i) the surrender of the Warrant, together with a duly executed
copy of the form of Exercise Notice attached hereto, to the Secretary of the
Company at its principal offices; and (ii) the payment to the Company by cash,

                                       1
<PAGE>

check or wire transfer of an amount equal to the aggregate Exercise Price for
the number of Shares being purchased.

                  4.  NET ISSUANCE PROVISION. In lieu of exercising
pursuant to paragraph 3 above, at the Holder's option, while this Warrant
remains outstanding and exercisable during the Exercise Period, Holder may
exercise this Warrant by surrender of this Warrant as determined below ("Net
Issuance"). If the Holder elects the Net Issuance method, the Company will issue
Common Stock in accordance with the following formula:

                      X =      Y(A-B)
                               ------
                                  A

                      Where:

                      X = the number of shares of Common Stock to be issued to
                          the Holder.

                      Y = the number of shares of Common Stock requested to be
                          exercised under this Warrant Agreement.

                      A = the fair market value of one (1) share of Common
                          Stock.

                      B = the Exercise Price.

                      For purposes of the above calculation, current fair market
value of Common Stock shall mean with respect to each share of Common Stock:

                      (i) if the exercise is in connection with an initial
         public offering of the Company's Common Stock, and if the Company's
         registration statement relating to such public offering has been
         declared effective by the Securities and Exchange Commission (the
         "SEC"), then the fair market value per share shall be the initial
         "Price to Public" specified in the final prospectus with respect to the
         offering;

                      (ii) if at any time the Common Stock is not listed on
         any securities exchange or quoted in the Nasdaq System or the
         over-the-counter market, the current fair market value of Common Stock
         shall be determined in good faith by the Board of Directors of the
         Company.

                      Upon partial exercise by either cash or Net Issuance,
the Company shall promptly issue an amended Warrant representing the remaining
number of shares purchasable thereunder. All other terms and conditions of such
amended Warrant shall be identical to those contained herein, including, but not
limited to, the Exercise Period.

                  5.  CERTIFICATES FOR SHARES. Upon the exercise of the
purchase rights evidenced by this Warrant, one or more certificates for the
number of Shares so purchased shall be issued as soon as practicable thereafter.
Upon any partial exercise of this Warrant, the Company will forthwith issue and
deliver to Holder a new warrant or warrants of like tenor as this Warrant for
the remaining portion of the Common Stock for which this Warrant may still be
exercised.

                                       2
<PAGE>

                  6.  ISSUANCE OF SHARES. The Company covenants that (a)
the Shares, when issued pursuant to the exercise of this Warrant, will be duly
and validly issued, fully-paid and non-assessable and free from all taxes, liens
and charges with respect to the issuance thereof (except for any applicable
transfer taxes, which shall be paid by Holder) and (b) during the Exercise
Period, the Company will reserve from its authorized and unissued Common Stock a
sufficient number of shares to provide for the issuance of Common Stock upon the
exercise of this Warrant.

                  7.  ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES.
The number of and kind of securities purchasable upon exercise of this Warrant
and the Exercise Price shall be subject to adjustment from time to time as
follows:

                      (a) SUBDIVISIONS, COMBINATIONS AND OTHER
         ISSUANCES. If the Company shall at any time prior to the expiration of
         this Warrant subdivide its Common Stock, by split or otherwise, or
         combine its Common Stock, or issue additional shares of its Common
         Stock as a dividend with respect to any shares of its Common Stock, the
         number of Shares issuable on the exercise of this Warrant shall
         forthwith be proportionately increased in the case of a subdivision or
         stock dividend, or proportionately decreased in the case of a
         combination. Appropriate adjustments shall also be made to the purchase
         price payable per share, but the aggregate purchase price payable for
         the total number of Shares purchasable under this Warrant (as adjusted)
         shall remain the same. Any adjustment under this Section 7(a) shall
         become effective as of the record date of such subdivision, combination
         or dividend, or in the event that no record date is fixed, upon the
         making of such subdivision, combination or dividend.

                      (b) RECLASSIFICATION, REORGANIZATION AND
         CONSOLIDATION. In case of any reclassification, capital reorganization,
         or change in the Common Stock of the Company (other than as a result of
         a subdivision, combination, or stock dividend provided for in Section
         7(a) above), then, as a condition of such reclassification,
         reorganization or change, lawful provision shall be made, and duly
         executed documents evidencing the same from the Company or its
         successor shall be delivered to Holder, so that Holder shall have the
         right at any time prior to the expiration of this Warrant to purchase,
         at a total price equal to that payable upon the exercise of this
         Warrant, the kind and amount of shares of stock and other securities
         and property receivable in connection with such reclassification,
         reorganization or change by a holder of the same number of shares of
         Common Stock as were purchasable by Holder immediately prior to such
         reclassification, reorganization or change. In any such case,
         appropriate provisions shall be made with respect to the rights and
         interest of Holder so that the provisions hereof shall thereafter be
         applicable with respect to any shares of stock or other securities and
         property deliverable upon exercise hereof, and appropriate adjustments
         shall be made to the purchase price per share payable hereunder,
         provided the aggregate purchase price shall remain the same.

                      (c)  MERGER AND SALE OF ASSETS. If at any time there
         shall be a capital reorganization of the shares of the Company's
         stock (other than a combination, reclassification, exchange or
         subdivision of shares otherwise provided for herein), or a merger or
         consolidation of the Company with or into another corporation, whether
         or not the Company is the surviving corporation, or the sale of all or
         substantially all of the

                                       3
<PAGE>

         Company's properties and assets to any other person (hereinafter
         referred to as a "Merger Event"), then, as a part of such Merger Event,
         lawful provision shall be made so that the Holder shall thereafter be
         entitled to receive, upon exercise of the Warrant, the number of shares
         of common stock or other securities of the successor corporation
         resulting from such Merger Event equivalent in value to that which
         would have been issuable if Holder had exercised this Warrant
         immediately prior to the Merger Event. In any such case, appropriate
         adjustment (as determined in good faith by the Company's Board of
         Directors) shall be made in the application of the provisions of this
         Warrant with respect to the rights and interest of the Holder after the
         Merger Event to the end that the provisions of this Warrant (including
         adjustments of the Exercise Price and number of shares of Common Stock
         purchasable) shall be applicable to the extent possible.

                      (d) CERTIFICATE OF ADJUSTMENT. When any adjustment is
         required to be made in the number or kind of shares purchasable upon
         exercise of the Warrant or in the Exercise Price, an officer of the
         Company shall promptly compute such adjustment in accordance with the
         terms of this Warrant and prepare a certificate setting forth, in
         reasonable detail, the event requiring the adjustment, the amount of
         the adjustment, the method by which such adjustment was calculated and
         the Exercise Price and number of shares purchasable hereunder after
         giving effect to such adjustment, and shall cause a copy of such
         certificate to be mailed (by first class mail, postage prepaid) to
         Holder.

                  8.  COMPLIANCE WITH SECURITIES LAWS.  Holder hereby represents
 and warrants that:

                      (a) PURCHASE ENTIRELY FOR OWN ACCOUNT. This Warrant and
         the Common Stock issuable upon exercise hereof (collectively, the
         "Securities") will be acquired for investment for Holder's own account,
         not as a nominee or agent, and not with a view to the resale or
         distribution of any part thereof, and Holder has no present intention
         of selling, granting any participation in or otherwise distributing the
         same. Holder does not have any contract, undertaking, agreement or
         arrangement with any person to sell, transfer or grant participation to
         any person with respect to any of the Securities. Holder represents
         that it has full power and authority to enter into this Warrant.

                      (b) INVESTMENT EXPERIENCE. Holder acknowledges that it is
         able to fend for itself, can bear the economic risk of its investment
         and has such knowledge and experience in financial or business matters
         that it is capable of evaluating the merits and risks of the investment
         in this Warrant. Holder also represents it has not been organized for
         the purpose of acquiring this Warrant.

                      (c) ACCREDITED INVESTOR. Holder is an "accredited
         investor" within the meaning of Rule 501 of Regulation D of the
         Securities and Exchange Commission (the "SEC"), as presently in effect.

                      (d) RESTRICTED SECURITIES. Holder understands that
         the Securities are characterized as "restricted securities" under the
         federal securities laws inasmuch as they are being acquired from the
         Company in a transaction not involving a public offering,

                                       4
<PAGE>

         and that under such laws and applicable regulations such securities may
         be resold without registration under the Act only in certain limited
         circumstances. In this connection, Holder represents that it is
         familiar with SEC Rule 144 promulgated under the Act, as presently in
         effect, and understands the resale limitations imposed thereby and by
         the Act.

                  9. FURTHER LIMITATIONS ON DISPOSITION. Without in any way
limiting the representations set forth above, Holder further agrees not to make
any disposition of all or any portion of the Securities unless and until there
is then in effect a registration statement under the Act covering such proposed
disposition and such disposition is made in accordance with such registration
statement, or (i) Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, (ii) the transferee
Holder shall have agreed in writing to become bound by the restrictions
applicable to the transferor Holder, including without limitation, the
provisions of this Section 9 and Section 17 hereof, and shall make the
representations and warranties set forth in Section 8 hereof in favor of the
Company and (iii) if requested by the Company, Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the Act.

                  10. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or
scrip representing fractional shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional shares the Company shall make a cash
payment therefor on the basis of the fair market value of the Company's Common
Stock as determined in good faith by the Company's Board of Directors.

                  11. NO STOCKHOLDER RIGHTS. Prior to exercise of this Warrant,
Holder shall not be entitled to any rights of a stockholder with respect to the
Shares, including (without limitation) the right to vote such Shares, receive
dividends or other distributions thereon, exercise preemptive rights or be
notified of stockholder meetings, and Holder, as such, shall not be entitled to
any notice or other communication concerning the business or affairs of the
Company, except as set forth in Section 7(d) above.

                  12. REPLACEMENT OF WARRANT. 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 substance 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 and amount.

                  13. NOTICES. All notices or other communications hereunder
shall be in writing and shall be deemed given when (i) personally delivered,
(ii) three business days after being sent by prepaid certified or registered
U.S. mail, or one business day after being sent, if sent by nationally
recognized overnight courier via overnight delivery, to the address of the party
