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.

such form and amounts as Silicon may reasonably require, and Borrower shall

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

                                            Rate.

                         (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:
<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 supplement 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 state 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 circumstance 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
<PAGE>

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 statements (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.
<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
<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.
<PAGE>

                  2.5    NOTICES, ETC. All notices and other communications
required or permitted hereunder shall be in writing and shall be mailed by first
class mail, postage prepaid, certified or registered mail, return receipt
requested, addressed (a) if to Holder, at such Holder's address as set forth
below, or at such other address as such Holder 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 other address as the Company shall have furnished to the
Holder in writing.

                  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 Agreements shall not in any way be affected or impaired thereby,

                  2.7    TITLES AND SUBTITLES. The titles of the sections  and
subsections of this Agreement are for  convenience of reference only and are not
to be considered in construing this Agreement.

                  2.8    COUNTERPARTS.  This  Agreement may be  executed  in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument.
