SILICON VALLEY BANK

LOAN AND SECURITY AGREEMENT

BORROWER:         WIRELESS, INC.
ADDRESS:          19 DAVIS DRIVE
                  BELMONT, CALIFORNIA 94002

DATE:             FEBRUARY 27, 1999

THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address"). The Schedule to this Agreement (the
"Schedule") shall for all purposes be deemed to be a part of this Agreement, and
the same is an integral part of this Agreement. (Definitions of certain terms
used in this Agreement are set forth in Section 8 below.)

1.       LOANS.

         1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), in
amounts determined by Silicon in its sole discretion, up to the amounts (the
"Credit Limit") shown on the Schedule, provided no Default or Event of Default
has occurred and is continuing, and subject to deduction of any Reserves for
accrued interest and such other Reserves as Silicon deems proper from time to
time.

         1.2 INTEREST. All Loans and all other monetary obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

         1.3 OVERADVANCES. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrowers obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rote equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

         1.4 FEES. Borrower shall pay Silicon the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Silicon and are
not refundable.

         1.5 LETTERS OF CREDIT. At the request of Borrower, Silicon may, in its
sole discretion, issue or arrange for the issuance of letters of credit for the
account of Borrower, in each case in form and substance satisfactory to Silicon
in its sole discretion (collectively, "Letters of Credit"). The aggregate face
amount of all outstanding Letters of Credit from time to time shall not exceed
the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder. Borrower
shall pay all bank charges (including charges of Silicon) for the issuance of
Letters of Credit, together with such additional fee as Silicon's letter of
credit department shall charge in connection with the issuance of the Letters of
Credit. Any payment by Silicon under or in connection with a Letter of Credit
shall constitute a Loan hereunder on the date such payment is made. Each Letter
of Credit shall have an expiry date no later than thirty days prior to the
Maturity Date. Borrower hereby agrees to indemnify, save, and hold Silicon
harmless from any loss, cost, expense, or liability, including payments made by
Silicon expenses, and reasonable attorneys' fees incurred by Silicon arising out
of or in connection with any Letters of Credit. Borrower agrees to be bound by
the regulations and interpretations of the issuer of any Letters of Credit
guarantied by Silicon and opened for Borrower's account or by Silicon's
interpretations of any Letter of Credit issued by Silicon for Borrower's
account, and Borrower understands and agrees that Silicon shall not be liable
for any error, negligence, or mistake, whether of omission or commission, in
following Borrower's instructions or those contained in the Letters of Credit
or any modifications,
<PAGE>

amendments, or supplements thereto. Borrower understands that Letters of Credit
may require Silicon to indemnify the issuing bank for certain costs or
liabilities arising out of claims by Borrower against such issuing bank.
Borrower hereby agrees to indemnify and hold Silicon harmless with respect to
any loss, cost, expense, or liability incurred by Silicon under any Letter of
Credit as a result of Silicon's indemnification of any such issuing bank. The
provisions of this Loan Agreement, as it pertains to Letters of Credit, and any
other present or future documents or agreements between Borrower and Silicon
relating to Letters of Credit are cumulative.

2.       SECURITY INTEREST.

         2.1 SECURITY INTEREST. To secure the payment and performance of all of
the Obligations when due, Borrower hereby grants to Silicon a security interest
in all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located (collectively, the "Collateral"): All Inventory,
Equipment, Receivables, and General Intangibles, including, without limitation,
all of Borrower's Deposit Accounts, and all money, and all property now or at
any time in the future in Silicon's possession (including claims and credit
balances), and all proceeds (including proceeds of any insurance policies,
proceeds of proceeds and claims against third parties), all products and all
books and records related to any of the foregoing (all of the foregoing,
together with all other property in which Silicon may now or in the future be
granted a lien or security, interest, is referred to herein, collectively, as
the "Collateral").

3.       REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

         In order to induce Silicon to enter into this Agreement and to make
Loans, Borrower represents and warrants to Silicon as follows, and Borrower
covenants that the following representations will continue to be true, and that
Borrower will at all times comply with all of the following covenants:

         3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is
and will continue to be, duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation. Borrower is and will
continue to be qualified and licensed to do business in all jurisdictions in
which any failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

         3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

         3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth
in the heading to this Agreement is Borrower's chief executive office. In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule. Borrower will give Silicon at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.

         3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at
all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower. The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens. Silicon now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Silicon and the Collateral against all claims
of others. None of the Collateral now is or will be affixed to any real property
in such a manner, or with such intent, as to become a fixture. Borrower is not
and will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises. Whenever any Collateral
is located upon premises in which any third party has an interest (whether as
owner, mortgagee beneficiary under a deed of trust, lien or otherwise), Borrower
shall, whenever requested by Silicon, use its best efforts to cause such third
party to execute and deliver to Silicon, in form acceptable to Silicon, such
waivers and subordinations as Silicon shall specify, so as to ensure that
Silicon's rights in the Collateral are, and will continue to be, superior to the
rights of any such third party. Borrower will keep in full force and effect, and
will comply with all the terms of, any lease of real property where any of the
Collateral now or in the future may be located.

         3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in
good working condition, and Borrower will not use the Collateral for any
unlawful purpose. Borrower will immediately advise Silicon in writing of any
material loss or damage to the Collateral.
<PAGE>

         3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

         3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial
statements now or in the future delivered to Silicon have been, and will be,
prepared in conformity with generally accepted accounting principles and now and
in the future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date hereof, there has
been no material adverse change in the financial condition or business of
Borrower. Borrower is now and will continue to be solvent.

         3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments, deposits
and contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrowers obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

         3.9 COMPLIANCE WITH LAW. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

         3.10 LITIGATION. Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of Borrower, or
in any material impairment in the ability of Borrower to carry on its business
in substantially the same manner as it is now being conducted. Borrower will
promptly inform Silicon in writing, of any claim, proceeding, litigation or
investigation in the future threatened or instituted by or against Borrower
involving any single claim of $50,000 or more, or involving $100,000 or more in
the aggregate.

standard forms; provided, however, that Borrower's failure to execute and

rights in all of Borrower's Receivables, nor shall Silicon's failure to advance
or lend against a specific Receivable affect or limit Silicon's security
interest and other rights therein. Loan requests received after 12:00 Noon will

credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $500 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement. Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,

Silicon, Silicon may, in its sole discretion, refuse to make any further Loans

remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower

or security, relating thereto required by any statute, court role or otherwise

interest at a rate equal to the highest interest rate applicable to any of the
Obligations. Without limiting any of Silicon's rights and remedies from and
after the occurrence of any Event of Default, the interest rate applicable to
the Obligations shall be increased by an additional four percent per annum.

         7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and

Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to

sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be

of noticing and selling the Collateral in its discretion, if they are
commercially reasonable.

without limiting Silicon's other rights
<PAGE>

and remedies, Borrower grants to Silicon an irrevocable power of attorney

of its employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Silicon agrees
to exercise the following powers in a commercially reasonable manner: (a)
Execute on behalf of Borrower any documents that Silicon may, in its sole
discretion, deem advisable in order to perfect and maintain Silicon's security
interest in the Collateral, or in order to exercise a right of Borrower or
Silicon, or in order to fully consummate all the transactions contemplated under
this Agreement and all other present and future agreements; (b) Execute on
behalf of Borrower any document exercising, transferring or assigning any option
to purchase, sell or otherwise dispose of or to lease (as lessor or lessee) any
real or personal property which is part of Silicon's Collateral or in which

relating to any Receivable, any draft against any Account Debtor and any notice

of mechanic's, materialman's or other lien; (d) Take control in any manner of
any cash or non-cash items of payment or proceeds of Collateral; endorse the

insurance claim that relates to any of the Collateral and obtain payment

records belonging to, or relating to, Borrower to give Silicon the same rights

Agreement; and (k) Take any action or pay any sum required of Borrower pursuant
to this Agreement and any other present or future agreements. Any and all
reasonable sums paid and any and all reasonable costs, expenses, liabilities,
obligations and attorneys' fees incurred by Silicon with respect to the
foregoing shall be added to and become part of the Obligations, shall be payable
on demand, and shall bear interest at a rate equal to the highest interest rate
applicable to any of the Obligations. In no event shall Silicon's rights under
the foregoing power of attorney or any of Silicon's other rights under this
Agreement be deemed to indicate that Silicon is in control of the business,
management or properties of Borrower.

         7.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of any
sale of the Collateral shall be applied by Silicon first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion.
Any surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

         7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set
forth in this Agreement, Silicon shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its or remedies shall not be deemed an election, nor
bar Silicon from subsequent exercise or partial exercise of any other rights or
remedies. The failure or delay of Silicon to exercise any rights or remedies
shall not operate as a waiver thereof, but all rights and remedies shall
continue in full force and effect until all of the Obligations have been fully
paid and performed.

checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after
receipt by Silicon of immediately available funds, and, for purposes of the

Borrower's account for the amount of any item of payment which is unsatisfactory
to Silicon in its sole discretion, and Silicon may charge Borrower's loan
account for the amount of any item of payment which is returned to Silicon
unpaid.

         9.2 APPLICATION OF PAYMENTS. All payments with respect to the
Obligations may be applied, and in Silicon's sole discretion reversed and
reapplied, to the Obligations, in such order and manner as Silicon shall
determine in its sole discretion.

Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate

NO ORAL UNDERSTANDINGS, REPRESENTATIONS OR AGREEMENTS BETWEEN THE PARTIES WHICH
ARE NOT SET FORTH IN THIS AGREEMENT OR IN OTHER WRITTEN AGREEMENTS SIGNED BY THE
PARTIES IN CONNECTION HEREWITH.

         9.8 WAIVERS. The failure of Silicon at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Silicon shall not waive
or diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been

by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,

waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Silicon.

         9.11 TIME OF ESSENCE.  Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

         9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for
all reasonable attorneys' fees and all filing, recording, search, title
insurance, appraisal, audit, and other reasonable costs incurred by Silicon,

the enforcement of, execution upon or defense of any order, decree, award or
judgment. All attorneys' fees and costs to which Silicon may be entitled
pursuant to this Paragraph shall immediately become part of Borrower's
Obligations, shall be due on demand, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations.
<PAGE>

         9.13 BENEFIT OF AGREEMENT . The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Silicon; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Silicon, and any prohibited
