Date up to the second full business day prior to the Closing Date by delivery of
written notice thereof to the Company (the "Cash Election"), to pay up to 35% of

Company Series A Preferred Stock, Company Series B Preferred Stock, Company
Series B-1 Preferred Stock and Company Series B-2 Preferred Stock that is issued
and outstanding immediately prior to the Effective Time shall, by virtue of the

Company immediately prior to the Effective Time shall be cancelled and
extinguished without any conversion thereof.

          2.2.5 Fractional Shares. No fractional shares of Acquirer Common Stock

Company Stock who would otherwise be entitled to receive a fraction of a share
of Acquirer Common Stock pursuant to Section 2.2.2, computed after aggregating
all shares of Acquirer Common Stock to be received by such holder pursuant to
Section 2.2.2, shall instead receive from Acquirer, upon surrender of such
holder's Company Certificates pursuant to Article 7, an amount of cash (rounded
to the nearest cent) equal to the product obtained by multiplying (a) the
Acquirer Average Price Per Share by (b) the fraction of a share of Acquirer
Common Stock that such holder would otherwise have been entitled to receive.

          2.2.6 Continuation of Vesting and Repurchase Rights. If any shares of
Company Stock outstanding immediately prior to the Effective Time are unvested
or subject to a repurchase option, vesting schedule or any other condition
providing that such shares may be forfeited to or repurchased by the Company
upon any termination of the relevant relationship (including employment or
directorship) of the Company with the holder (or prior holder thereof) under the
terms of any restricted stock purchase agreement, stock option agreement
(including any stock option agreement under the Company Plan) or other agreement
with the Company (such shares being referred to herein as "Unvested Company
Shares"), then such repurchase option, vesting schedule or other condition shall
be assigned to Acquirer and the shares of Acquirer Common Stock issued upon the
conversion of such Unvested Company Shares in the Merger shall continue to be
unvested and shall continue to be subject to the same repurchase options,
vesting schedules or other conditions, as applicable, immediately following the
Effective Time as they were subject to immediately prior to the Effective Time.
The cash payable upon conversion of Unvested Company Shares shall be withheld by
Acquirer and paid to each such holder upon the vesting of the shares of Acquirer
Common Stock issued upon conversion of such Unvested Company Shares. The
certificates representing such shares of Acquirer Common Stock shall accordingly
be marked with appropriate legends noting such repurchase options, vesting
schedules or other conditions. The Company shall take all actions that are
reasonably necessary to ensure that, from and after the Effective Time, Acquirer
(or its assignee) shall be entitled to exercise any such repurchase option,
vesting schedule or other right set forth in any such restricted stock purchase
agreement, vesting schedule or other agreement.

          2.2.7 Adjustment of Total Consideration.

          (a) At least two business days prior to the Closing (as scheduled in
accordance with Section 7.1), the Company shall deliver to Acquirer its
calculation of the Company's Tangible Net Worth as of the Closing and, if the
Closing is scheduled to occur after August 31, 2002, the Company's Tangible Net
Worth as of August 31, 2002 (collectively, the "Closing TNW Calculations"). The
Closing TNW Calculations shall be in accordance with GAAP and shall include all
of the line items specified in the definition of Tangible Net Worth. The Closing
TNW Calculations shall be accompanied by a certificate of the Company's Chief
Executive Officer representing and warranting to Acquirer that the Closing TNW
Calculations are true, correct and complete in all material respects, have been
prepared in accordance with GAAP and fairly present the financial position of
the Company as of the Closing and as of August 31, 2002, as applicable (the "TNW
Certificate"). The representations in the Closing TNW Calculations and the
accompanying TNW Certificate shall be deemed representations of the Company for
purposes of Article 11. Unless, in Acquirer's reasonable judgment after good
faith negotiation with the Company, the Closing TNW Calculations contain a
manifest error, Acquirer shall accept the Closing TNW Calculations (the "Closing
Acceptance") for purposes of determining the Total Consideration as of the
Closing.

          (b) Within 45 days after the Closing and notwithstanding the Closing
Acceptance, Acquirer may object to the Closing TNW Calculations by written
notice to the Representative. If Acquirer does not object to the Closing TNW
Calculations within such 45-day period, then Acquirer shall be deemed to have
agreed with the Closing TNW Calculations for purposes of this Section 2.2.7.
Acquirer's objection to the Closing TNW Calculations, if any, shall include
Acquirer's revised calculations of the Company's Tangible Net Worth as of the
Closing and, if the Closing occurred after August 31, 2002, the Company's
Tangible Net Worth as of August 31, 2002 (collectively, the "Post-Closing TNW
Calculations"). Within 15 days after the Representative's receipt of the
Post-Closing TNW Calculations, the Representative may object to the Post-Closing
TNW Calculations by written notice to Acquirer setting forth the basis for the
Representative's rejection of some or all of the calculations set forth in the
Post-Closing TNW Calculations (the "Representative's Objection"). If the
Representative does not object to the Post-Closing TNW Calculations within such
15-day period or if the Representative agrees with the Post-Closing TNW
Calculations by delivering a written confirmation thereof to Acquirer within the
specified 15-day period, then the Representative shall be deemed to have
conclusively agreed with and shall be bound by the Post-Closing TNW Calculations
for purposes of this Section 2.2.7 and Acquirer shall have the right to recover
the difference between the reductions to the Total Consideration pursuant to
Sections 2.2.7(c) and 2.2.7(d) using the Post-Closing TNW Calculations (the
"Post-Closing Reductions") and the Closing Reductions (as defined below) in
accordance with Article 11, including the forfeiture of all or a portion of the
Escrow Fund. Acquirer and the Representative shall confer in good faith for a
period of up to 15 days following Acquirer's receipt of the Representative's
Objection, if any, concerning the subject matter of the Representative's
Objection in an attempt to resolve it. If, after such 15-day period, Acquirer
and the Representative cannot agree, then the parties shall attempt to agree
upon a mutually satisfactory nationally recognized auditing firm (the "Firm");
provided, however, that if the parties cannot agree on a mutually satisfactory
nationally recognized auditing firm, then each of Acquirer and the
Representative shall select a nationally recognized auditing firm and the two
firms so


                                       15

<PAGE>

selected by Acquirer and the Representative shall select the Firm. The Firm
shall review the Closing TNW Calculations and the Post-Closing TNW Calculations
and make a final written determination of the Company's Tangible Net Worth as of
the Closing and, if the Closing occurred after August 31, 2002, the Company's
Tangible Net Worth as of August 31, 2002 (the "Firm Calculations"), which
determination shall be conclusive and binding on Acquirer, the Representative,
the Company and the Company Stockholders. The Firm's engagement pursuant to this
Section 2.2.7(b) shall be limited solely to determining the Company's Tangible
Net Worth as of the Closing and, if the Closing occurred after August 31, 2002,
the Company's Tangible Net Worth as of August 31, 2002. If the reductions to the
Total Consideration pursuant to Sections 2.2.7(c) and 2.2.7(d) using the Firm
Calculations (the "Final Reductions") are greater than the reductions to the
Total Consideration pursuant to Sections 2.2.7(c) and 2.2.7(d) using the Closing
TNW Calculations (the "Closing Reductions"), then Acquirer shall have the right
to recover the difference between the Final Reductions and the Closing
Reductions in accordance with Article 11, including the forfeiture of all or a
portion of the Escrow Fund. Acquirer and the Company Stockholders (in proportion
to each Company Stockholder's Pro Rata Share) shall initially bear the fees and
expenses, in equal proportions, of the Firm in connection with its engagement
pursuant to this Section 2.2.7(b). If the Final Reductions are greater than the
Closing Reductions, then Acquirer shall be deemed to be the prevailing party and
the Company Stockholders (in proportion to each Company Stockholder's Pro Rata
Share) shall be deemed to be the non-prevailing party. If the Final Reductions
are less than or equal to the Closing Reductions, then the Company Stockholders
shall be deemed to be the prevailing party and Acquirer shall be deemed to be
the non-prevailing party. The non-prevailing party shall pay all reasonable
costs, fees and expenses related to the Firm's engagement pursuant to this
Section 2.2.7(b), including reasonable fees and expenses of attorneys,
accountants and other professionals incurred by the prevailing party; provided,
however, that if the Company Stockholders are deemed to be the non-prevailing
party then the Company Stockholders shall satisfy their obligation under this
sentence by forfeiture of all or a portion of the Escrow Fund as provided in
Article 11.

          (c) If (i) the Company's Tangible Net Worth as of the Closing (the
"Closing TNW") is a more negative amount than negative $2,000,000 and (ii) the
Closing occurs on or before August 31, 2002, then the Total Consideration shall
be reduced by $1.00 for each $1.00 by which the Closing TNW is more negative
than negative $2,000,000.

          (d) If (i) the Closing TNW is a more negative amount than negative
$2,000,000 and (ii) the Closing occurs after August 31, 2002, then the Total
Consideration shall be reduced as provided in this Section 2.2.7(d). If the
Company's Tangible Net Worth as of August 31, 2002 (the "August 31 TNW") is a
more negative amount than negative $2,000,000, then the Total Consideration
shall be reduced by (A) $1.00 for each $1.00 by which the August 31 TNW is more
negative than negative $2,000,000 and by (B) $0.50 for each $1.00 by which the
Closing TNW is more negative than the August 31 TNW; provided, however, that,
for purposes of clause (B), if the amount by which the Closing TNW is more
negative than the August 31 TNW exceeds the Threshold, then the Total
Consideration shall be reduced by $0.50 for each dollar in reduction until the
Threshold is reached and by $1.00 for each dollar in reduction in excess of the
Threshold. If the August 31 TNW is a less negative amount than (or a positive
amount) or equal to negative $2,000,000, then the Total Consideration shall be
reduced by $0.50 for each $1.00 by which the Closing TNW is more negative than
negative $2,000,000;


                                       16

<PAGE>

provided, however, that if the amount by which the Closing TNW is more negative
than the August 31 TNW exceeds the Threshold, then the Total Consideration shall
be reduced by $0.50 for each dollar in reduction until the Threshold is reached
and by $1.00 for each dollar in reduction in excess of the Threshold.

          (e) "Threshold" means, (i) if the Closing occurs on September 30,
2002, $1,470,705, and (ii) if the Closing occurs before September 30, 2002, the
product of (A) $1,470,705 multiplied by (B) the quotient obtained by dividing
(x) the number of days that have elapsed between August 31, 2002 and the Closing
Date by (y) 30.

     2.3 Adjustments for Capital Changes. Notwithstanding the provisions of this
Article 2, if Acquirer effects a subdivision (or stock split) of any of the
outstanding shares of Acquirer Common Stock into a greater number of such
shares, or a combination (or reverse stock split) of any of the outstanding
shares of Acquirer Common Stock into a lesser number of such shares, or
reorganizes, reclassifies or otherwise changes its outstanding shares of
Acquirer Common Stock into the same or a different number of shares of other
classes or series of Acquirer stock (other than through a subdivision or
combination of shares provided for in the preceding clause), or declares a
dividend or other distribution on the outstanding shares of Acquirer Common
Stock payable in shares of Acquirer Common Stock, in shares or securities
convertible into shares of Acquirer Common Stock and/or other Acquirer equity
securities, or is a party to a merger or consolidation with or into another
corporation in which Acquirer is not the surviving entity (or is a party to a
reverse triangular merger is which Acquirer is the surviving entity) and the
shares of Acquirer's capital stock outstanding immediately prior to the merger
or consolidation are converted into such other corporation's securities, cash or
other property (each, a "Capital Change"), at any time after the Agreement Date
and prior to the Effective Time, then the Common Conversion Number, the Series A
Preferred Conversion Number, the Series B Preferred Conversion Number, the Cash
Adjusted Common Conversion Number, the Cash Adjusted Series A Preferred
Conversion Number, the Cash Adjusted Series B Preferred Conversion Number and
the Option Conversion Number shall be equitably adjusted.

     2.4 Company Options. At the Effective Time, all outstanding options to
purchase shares of Company Common Stock (collectively, "Company Options"),
including all Company Options granted under the Company's 2000 Stock
Option/Stock Issuance Plan (the "Company Plan"), shall be assumed by Acquirer
and the Company's repurchase right with respect to any unvested shares of
Company Common Stock acquired upon the exercise of Company Options shall be
assigned to Acquirer. Each Company Option so assumed by Acquirer shall be
entitled, in accordance with the terms of such option, to purchase after the
Effective Time that number of shares of Acquirer Common Stock determined by
multiplying (a) the number of shares of Company Common Stock subject to such
Company Option at the Effective Time by (b) the Option Conversion Number. After
the Effective Time, the exercise price per share for each such assumed Company
Option shall equal the exercise price per share of the Company Option
immediately prior to the Effective Time divided by the Option Conversion Number.
If the foregoing calculations result in an assumed Company Option being
exercisable for a fraction of a share or a fraction of a cent, then the number
of shares of Acquirer Common Stock subject to such option shall be rounded down
to the nearest whole number and the exercise price of such option shall be
rounded up to the nearest cent. Except as specifically set forth in Schedule
3.4.2(a)(vi) of the Company Disclosure Letter, no Company Options shall become


                                       17

<PAGE>

vested or exercisable solely as a result of the Merger. To the extent permitted
by Applicable Laws and otherwise consistent with the terms of this Agreement,
the term, exercisability, vesting schedule, status as an "incentive stock
option" under Section 422 of the Code, if applicable, and all other terms of the
assumed Company Options as in effect immediately prior to the Effective Time
shall otherwise be unchanged.

     2.5 Company Warrants; Preferred Rights. As of the Effective Time, all
outstanding Company Warrants and all outstanding options, warrants and other
rights to purchase shares of Company Series A Preferred Stock (collectively,
"Series A Preferred Rights") and all outstanding options, warrants and other
rights to purchase shares of Company Series B Preferred Stock, Company Series
B-1 Preferred Stock and Company Series B-2 Preferred Stock (collectively,
"Series B Preferred Rights" and together with the Series A Preferred Rights, the
"Preferred Rights") shall have been terminated in accordance with their terms or
shall have been exercised.

     2.6 Escrow. At the Effective Time, Acquirer shall withhold from the shares
of Acquirer Common Stock to be issued to the Company Stockholders in the Merger
upon conversion of their Company Stock pursuant to Section 2.2.2, each Company
Stockholder's Pro Rata Share of that aggregate number of shares of Acquirer
Common Stock having an aggregate value (based on the Acquirer Average Price Per
Share) equal to 11.25% of the Total Consideration (such withheld shares of
Acquirer Common Stock, the "Escrow Shares"). If a Company Stockholder holds
Unvested Company Shares, then the shares of Acquirer Common Stock to be issued
upon conversion hereunder of shares of Company Stock held by such Company
Stockholder which are not Unvested Company Shares ("Vested Company Shares")
shall be withheld and placed in escrow first and, thereafter, the Unvested
Company Shares shall be withheld and placed in escrow (with the understanding
that any Unvested Company Shares so placed in escrow shall vest prior to any
such Unvested Company Shares not placed in escrow) to the extent necessary to
satisfy such Company Stockholders' escrow obligations as set forth in the first
sentence of this Section 2.6. The payment of any Escrow Shares in satisfaction
of any indemnification obligations under Article 11 shall be made, with respect
to each Company Stockholder, first with Vested Company Shares and then, if such
shares are insufficient to satisfy such indemnification obligation and only to
the extent of such insufficiency, shall such payment be made with Unvested
Company Shares. Any shares of Acquirer Common Stock or other equity securities
issued or distributed by Acquirer (including shares issued upon a stock split,
stock dividend, recapitalization or other similar event) in respect of Escrow
Shares shall also be withheld in the Escrow Fund. Cash dividends on the Escrow
Fund shall not be added to the Escrow Fund but shall be distributed to the
record holders of the Escrow Fund. Acquirer shall hold the Escrow Shares as
security for the Company Stockholders' indemnification obligations for Damages
under Article 11.

     2.7 Effects of the Merger. At and upon the Effective Time, the effect of
the Merger shall be as provided in this Agreement and the applicable provisions
of the Delaware Law. Without limiting the generality of the foregoing, at the
Effective Time:

          (a) the Certificate of Incorporation of Merger Sub immediately prior
to the Effective Time shall be the Certificate of Incorporation of the Surviving
Corporation immediately after the Effective Time until thereafter amended in
accordance with the provisions


                                       18

<PAGE>

thereof or as provided by law; provided, however, that Article I of the
Certificate of Incorporation of the Surviving Corporation shall be amended at
the Effective Time to read: "The name of the corporation is OneSecure, Inc.";

          (b) the Bylaws of Merger Sub immediately prior to the Effective Time
shall continue unchanged and be the Bylaws of the Surviving Corporation
immediately after the Effective Time until thereafter amended in accordance with
the provisions thereof or as provided by law;

          (c) the directors of Merger Sub immediately prior to the Effective
Time shall become the initial directors of the Surviving Corporation until their
respective successors are duly elected or appointed and qualified; and

          (d) the corporate officers of Merger Sub immediately prior to the
Effective Time shall become the initial corporate officers of the Surviving
Corporation until their respective successors are duly appointed.

     2.8 Securities Law Issues; Registration Rights. Based in part upon the
representations of the Company Stockholders in their Investment Representation
Letters, Acquirer shall issue the shares of Acquirer Common Stock to be issued
to the Company Stockholders in the Merger under Section 2.2.2 pursuant to an
exemption or exemptions from registration under Section 4(2) of the Securities
Act and/or Regulation D promulgated under the Securities Act and the exemption
from qualification under the laws of the State of California and other
applicable state securities laws. Acquirer and the Company Stockholders will
enter into a registration rights agreement in the form attached hereto as
Exhibit H (the "Registration Rights Agreement") with respect to 70% of the
shares of Acquirer Common Stock issued to the Company Stockholders (excluding
the Escrow Shares) in exchange for shares of Company Stock. Subject to
compliance by Acquirer with its obligations under the Registration Rights
Agreement, holders of shares of Acquirer Common Stock to be issued in the Merger
will be wholly responsible for compliance with all federal and state securities
laws regarding the sale, transfer or other disposition of such shares.

     2.9 Tax Matters. The parties acknowledge their respective desire to
structure the Merger to constitute a "reorganization" within the meaning of
Section 368(a) of the Code; provided, however, that such tax treatment shall not
be a condition to either party's obligation to close the transactions
contemplated herein. Subject to the qualifications set forth in the preceding
sentence, (a) Acquirer and the Company shall use their reasonable good faith
efforts to achieve such tax treatment and (b) the parties hereto adopt this
Agreement as a "plan of reorganization" within the meaning of Sections
1.368-2(g) and 1.368-3(a) of the United States Income Tax Regulations. Acquirer
makes no representations or warranties to the Company or to any Company
Stockholder or other holder of Company securities regarding the tax treatment of
the Merger, whether the Merger shall qualify as a tax-free plan of
reorganization under the Code, or any of the tax consequences to any Company
Stockholder or other holder of Company securities of this Agreement, the Merger
or any of the other transactions or agreements contemplated hereby, and the
Company and the Company Stockholders acknowledge that the Company and the
Company Stockholders are relying solely on their own tax advisors in


                                       19

<PAGE>

connection with this Agreement, the Merger and the other transactions
contemplated by this Agreement.

     2.10 Further Assurances. If, at any time before or after the Effective
Time, Acquirer believes or is advised that any further instruments, deeds,
assignments or assurances are reasonably necessary or desirable to consummate
the Merger or to carry out the purposes and intent of this Agreement at or after
the Effective Time, then the Company, Acquirer, the Surviving Corporation and
their respective officers and directors shall execute and deliver all such
proper deeds, assignments, instruments and assurances and do all other things
necessary or desirable to consummate the Merger and to carry out the purposes
and intent of this Agreement.

                                   ARTICLE 3
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Acquirer that, except as set forth

jurisdiction where the character of the properties owned, leased or operated by
it or the nature of its activities makes such qualification or licensing

individually or in the aggregate have a Material Adverse Effect on the Company.
The Company has delivered to Acquirer's legal counsel true and complete copies
of the currently effective Certificate of Incorporation and Bylaws of the
Company, each as amended to date. The Company is not in violation of its
Certificate of Incorporation or Bylaws, each as currently in effect, or the
Restated Certificate (upon its approval and adoption by the Board of Directors
of the Company and the Company Stockholders and filing with and acceptance by
the Delaware Secretary of State as contemplated by this Agreement).

     3.2 Subsidiaries. The Company does not have any Subsidiary or any equity or
ownership interest, whether direct or indirect, in any corporation, partnership,
limited liability company, joint venture or other business entity. The Company

statements of changes in stockholders' equity for the six-month period ended
June 30, 2002 (all such financial statements of the Company and any notes
thereto, together with the financial statements of the Company delivered to
Acquirer pursuant to Section 9.21, are hereinafter collectively referred to as
the "Company Financial Statements"). In addition, the Company has delivered to
Acquirer as attachments to Schedule 3.8 of the Company Disclosure Letter true,
correct and complete copies of all material accounting policies used in
preparing the Company Financial Statements. Frank, Rimerman & Co. is currently
auditing the Company's financial statements for the fiscal years ended December
31, 2000 and December 31, 2001. Notwithstanding such audit by Frank, Rimerman &
Co., the Company Financial Statements: (a) are derived from and are in
accordance with the books and records of the Company; (b) fairly present the
financial condition of the Company at the dates therein indicated and the
results of operations for the periods therein specified; (c) have been prepared
in accordance with GAAP applied on a basis consistent with prior periods except
for any absence of notes to any of the unaudited Company Financial Statements;
and (d) are true, correct and complete in all material respects. The Company has
no debt, liability, obligation or commitment of any nature, whether accrued,
absolute, contingent or otherwise, and whether due or to become due, except for
those (a) shown on the Company's unaudited balance sheet as of June 30, 2002
included in the Company Financial Statements (the "Balance Sheet") and (b) that
may have been incurred after June 30, 2002 (the "Balance Sheet Date") in the
ordinary course of the Company's business consistent with its past practices and
that are, individually or in the aggregate, not material to the business results
of operations or financial condition of the Company. All reserves established by
the Company that are set forth in or reflected in the Balance Sheet are
adequate. At the Balance Sheet Date, there were no material loss contingencies
(as such term is used in Statement of Financial Accounting Standards No. 5
("Statement No. 5") issued by the Financial Accounting Standards Board in March
1975) that are not adequately provided for in the Balance Sheet as required by
Statement No. 5. The Company Financial Statements comply in all material
respects with the American Institute of Certified Public Accountants' Statement
of Position 97-2. The Company has not had any dispute with any of its auditors
regarding accounting matters or policies.

     3.9 Title to Properties. The Company has good and marketable title to, or
valid leasehold interests in or other valid rights to use, all of the assets and
properties (including those shown on the Balance Sheet) used in the Company
Business, free and clear of all Encumbrances, other than liens for current taxes
that are not yet due and payable and as shown in the Company Financial
Statements. Such assets are sufficient for the continued operation of the
Company Business. All machinery, vehicles, equipment and other tangible personal
property owned or leased by the Company or used in the Company Business are in
good condition and repair, normal wear and tear excepted, and all leases of real
or personal property to which the Company is a party are fully effective and
afford the Company peaceful and undisturbed leasehold possession of the real or
personal property that is the subject of the lease. The Company is not in
violation, in any material respect, of any zoning, building, safety or
environmental ordinance, regulation or requirement or other law or regulation
applicable to the operation of its owned or leased properties, nor has the
Company received any notice of violation of law with which it has not complied.
The Company does not own any real property. Schedule 3.9 of the Company
Disclosure Letter sets forth a complete and accurate list and a brief
description of all personal property, including capital equipment, owned or
leased by the Company with an individual value of $1,000 or greater.

contemplated by this Agreement and/or by the Company Ancillary Agreements shall,
in accordance with their terms: (a) constitute a material breach of or default
under any instrument, license or other contract, agreement, arrangement,
commitment or undertaking governing any Company IP Right (collectively, the
"Company IP Rights Agreements"); (b) cause the forfeiture or termination of, or
give rise to a right of forfeiture or termination of, any Company IP Right; or
(c) materially impair the right of the Company or the Surviving Corporation to
use, possess, sell or license any Company IP Right or portion thereof. There are
no royalties, honoraria, fees or other payments payable by the Company to any
third person (other than salaries payable to employees and independent
contractors not contingent on or related to use of their work product) as a
result of the ownership, use, possession, license-in, sale, marketing,
advertising or disposition of any Company IP Rights by the Company to the extent
necessary for the conduct of the Company Business and none shall become payable

sale, furnishing or intended use of any product or service currently licensed,
utilized, sold, provided or furnished by the Company or currently under
development by the Company violates any license or contract, agreement,
arrangement, commitment or undertaking between the Company and any third party
or infringes or misappropriates any Intellectual Property right of any other
party; and there is no pending or, to the Company's knowledge, threatened claim
or litigation contesting the validity, ownership or right of the Company to
exercise any Company IP Right, nor to the Company's knowledge, is there any
legitimate basis for any such claim, nor has the Company received any notice
asserting that any Company IP Right or the proposed use, sale, license or
disposition thereof conflicts or shall conflict with the rights of any other
party, nor, to the Company's knowledge, is there any legitimate basis for any
such assertion.

          3.13.4 No current or former employee, consultant or independent
contractor of the Company: (a) is (or, in the case of a former employee, was
during the time that such employee was employed by the Company) in material
violation of any term or covenant of any employment contract, patent disclosure
agreement, invention assignment agreement, nondisclosure agreement,
noncompetition agreement or any other contract, agreement, arrangement,
commitment or undertaking with any other party by virtue of such employee's,
consultant's or independent contractor's being employed by, or performing
services for, the Company or using trade secrets or proprietary information of
others without permission; or (b) has developed any technology, software or
other copyrightable, patentable or otherwise proprietary work for the Company
that is subject to any agreement under which such employee, consultant or
independent contractor has assigned or otherwise granted to any third party any
rights (including Intellectual Property) in or to such technology, software or
other copyrightable, patentable or otherwise proprietary work. The employment of
any employee of the Company or the use by the Company of the services of any
consultant or independent contractor does not subject the Company to any
liability to any third party for improperly soliciting such employee, consultant
or independent contractor to work for the Company, whether such liability is
based on contractual or other legal obligations to such third party.

          3.13.5 The Company has taken all necessary steps to protect, preserve

agreement regarding the protection of such proprietary information and the
assignment of inventions to the Company (in the case of proprietary information
of the Company's customers and business partners, to the extent required by such
customers and business partners); and copies of all such agreements have been
made available to Acquirer's legal counsel. The Company has secured valid
written assignments from all of the Company's current and former consultants,
contractors and employees who were involved in, or who contributed to, the
creation or development of any Company-Owned IP Rights, of the rights to such
contributions that may be owned by such persons or that the Company does not
already own by operation of law. No current or former employee, officer,
director, consultant or independent contractor of the Company has any right,
license, claim or interest whatsoever in or with respect to any Company-Owned IP
Rights or any Company IP Right that the Company purports to own.

Company-Licensed IP Rights (subject to the right, title and interest of the
third party that owns such underlying Company-Licensed IP Rights and has granted
a license to the Company in any such Company-Licensed IP Rights) are free and
clear of all Encumbrances, licenses and rights (other than licenses and rights
listed in Schedule 3.13.8 of the Company Disclosure Letter).

with such customers) to applicable contractual commitments, express and implied
warranties, product specifications and product documentation and to any
representations provided to customers, and the Company has no material liability
(and, to the Company's knowledge, there is no legitimate basis for any present
or future action, suit, proceeding, hearing, investigation, charge, complaint,
claim or demand against the Company giving rise to any material liability
relating to the foregoing contracts, agreements, arrangements, commitments and
undertakings) for replacement or repair thereof or other damages in connection
therewith in excess of any reserves therefor reflected on the Balance Sheet. The
Company has not received any written notice of any malfunctions with respect to
any of the Company's products or any other customer complaints related thereto

          3.13.12 No government funding, facilities of a university, college,
other educational institution or research center, or funding from third parties

     3.20 Insurance. The Company maintains policies of insurance of the type and
in amounts reasonably and customarily carried by persons conducting businesses
or owning assets similar in type and size and in similar industries to those of
the Company, including all legally required workers' compensation insurance and
errors and omissions, casualty, fire and general liability insurance. There is
no material claim pending under any of such policies as to which coverage has
been questioned, denied or disputed by the underwriters of such policies. All
premiums due and payable under all such policies have been timely paid, and the
Company is otherwise in material compliance with the terms of such policies. The
Company has no knowledge of any threatened termination of, or material premium
increase with respect to, any of such policies. All policies of insurance now
held by the Company are set forth in Schedule 3.20 of the Company Disclosure
Letter, together with the name of the insurer under each policy, the type of
policy, the coverage amount and any applicable deductible.

     3.21 Environmental Matters.

          3.21.1 The Company and its predecessors and affiliates are in material
compliance with all applicable Environmental Laws (as defined below), which
compliance includes the possession by the Company of all permits and other
governmental authorizations required under applicable Environmental Laws and
compliance with the terms and conditions thereof. The Company has not received
any notice or other communication (in writing or otherwise), whether from a
governmental body, citizens groups, employee or otherwise, that alleges that the
Company is not in compliance with any Environmental Law, and there are no
circumstances that could reasonably be expected to cause the Company not to be
materially in compliance with any current Environmental Law in the future. To
the Company's knowledge, no current or prior owner of any property leased or
possessed by the Company has received any notice or other communication (in
writing or otherwise), whether from a government body, citizens group, employee
or otherwise, that alleges that such current or prior owner or the Company is
not in compliance with any Environmental Law. All governmental authorizations
currently held by the Company pursuant to any Environmental Law (if any) are
identified in Schedule 3.21 of the Company Disclosure Letter.

          3.21.2 For purposes of this Section 3.21: (a) "Environmental Law"
means any federal, state or local statute, law, regulation or other legal
requirement relating to pollution or protection of human health or the
environment (including ambient air, surface water, ground water, land surface or
subsurface strata), including any law or regulation relating to emissions,
discharges, releases or threatened releases of Materials of Environmental
Concern or otherwise relating to the manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling of Materials of
Environmental Concern; and (b) "Material of Environmental Concern" include
chemicals, pollutants, contaminants, wastes, toxic substances, petroleum and
petroleum products and any other substances that are currently regulated by an
Environmental Law.

     3.22 Board Actions. The Company's Board of Directors, (a) has unanimously
determined that the Merger is advisable and in the best interests of the Company
Stockholders and is on terms that are fair to such Company Stockholders and has
recommended the Merger to the Company Stockholders and (b) shall submit the
Merger, this Agreement, each of the Company Ancillary Agreements and all other
agreements, transactions and actions contemplated


                                       41

<PAGE>

hereby and thereby (including the Restated Certificate), to the extent that
stockholder approval is required thereof under Applicable Laws and the Company's
Certificate of Incorporation and Bylaws, each as currently in effect, to the
vote and approval of the Company Stockholders.

     3.23 No Existing Discussions. Neither the Company nor any director,
officer, stockholder, employee or agent (or any investment banker, broker,
finder or similar party) of the Company is, or since July 22, 2002 has been,
engaged, directly or indirectly, in any discussions or negotiations with any
third party relating to any Alternative Transaction.

     3.24 Accounts Receivable. The accounts receivable shown on the Balance
Sheet arose in the Company's ordinary course of business, consistent with its
past practices, and have been collected or are believed by the Company,
reasonably and in good faith, to be collectible in the book amounts thereof,
less an amount not in excess of the allowance for doubtful accounts provided for
in the Balance Sheet. Allowances for doubtful accounts and warranty returns are
adequate and have been prepared in accordance with GAAP consistently applied and
in accordance with Company's past practices. The Company's receivables arising
after the Balance Sheet Date and before the Closing Date arose or will arise in
the Company's ordinary course of business based on bona fide sales, consistent
with its past practices, and have been collected or are collectible in the book
amounts thereof, less allowances for doubtful accounts and warranty returns
determined in accordance with GAAP consistently applied and the Company's past
practices. None of the Company's receivables is subject to any material claim of
offset, recoupment, setoff or counter-claim, and the Company has no knowledge of
any specific facts or circumstances (whether asserted or unasserted) that could
give rise to any such claim. No material amount of receivables is contingent
upon the performance by the Company of any obligation or contract other than
normal warranty repair and replacement. No person has any lien on any of such
receivables, and no agreement for deduction or discount has been made with
respect to any of such receivables. Schedule 3.24 of the Company Disclosure
Letter sets forth a true, correct and complete aging of the Company's accounts
receivable in the aggregate and by customer, and indicates the amounts of
allowances for doubtful accounts and warranty returns and the amounts of
accounts receivable which are subject to asserted warranty claims. Schedule 3.24
of the Company Disclosure Letter sets forth such amounts of the Company's
accounts receivable which are subject to asserted warranty claims by customers
and reasonably detailed information regarding asserted warranty claims made
within the last year, including the type and amounts of such claims.

     3.25 Customers. Schedule 3.25(a) of the Company Disclosure Letter lists the
customers who, in the year ended December 31, 2001 or the six-month period ended
June 30, 2002, were the 20 largest sources of revenues for the Company, based on
amounts paid (each, a "Significant Customer"). The Company has no outstanding
material disputes concerning its products and/or services with any Significant
Customer, and the Company has no knowledge of any material dissatisfaction on
the part of any Significant Customer with respect to the Company's products or
services. The Company has not received any information from any Significant
Customer that such customer will not continue as a customer of the Company (or
the Surviving Corporation) after the Closing or that such customer intends to
terminate or materially modify existing contracts, agreements, arrangements,
commitments or undertakings with the Company (or the Surviving Corporation). No
contract, agreement or arrangement between the Company and any of its
Significant Customers contains any provision that would or is


                                       42

<PAGE>

reasonably likely to (i) adversely affect the Company's ability to collect any
accounts receivable related to the sale of the Company's products to such
Significant Customer, (ii) adversely affect the Company's ability to recognize
revenue on the Company's financial statements from the sale of the Company's
products to such Significant Customer, or (iii) adversely affect such
Significant Customer's obligation to accept the Company's products. The Company
has not had any of its products returned by a purchaser thereof except for
normal warranty returns consistent with past history and those returns that
would not result in a reversal of any revenue by the Company. Schedule 3.25(b)
of the Company Disclosure Letter sets forth, for each customer service complaint
or report received by the Company within the 60-day period prior to the Closing,
the name of such customer, the date of such complaint and a brief description of
the nature of such complaint.

     3.26 Suppliers. Schedule 3.26(a) of the Company Disclosure Letter lists the
suppliers who, in the year ended December 31, 2001 or the six-month period ended
June 30, 2002, were the 20 largest suppliers of goods and services to the
Company, based on amounts paid (each, a "Significant Supplier"). The Company has
no outstanding material disputes concerning goods or services provided by any
Significant Supplier, and the Company has no knowledge of any quality issue with
respect to any of the goods or services provided to the Company by any
Significant Supplier. The Company has not received any written notice of
termination or interruption of any existing contracts, agreements, arrangements,
commitments or undertakings with any Significant Supplier. The Company has
access, on commercially reasonable terms, to all goods and services reasonably
necessary to it to carry on its business as currently conducted, and the Company
has no knowledge of any reason why it will not continue to have such access on
commercially reasonable terms.

     3.27 Privacy. The Company has not collected any personally identifiable
information from any third parties. The Company has provided adequate notice of
its privacy practices in its privacy policy or policies, which policy or
policies (and the periods such policy or policies have been in effect) are set
forth in Schedule 3.27 of the Company Disclosure Letter. The Company's privacy
policy is and has been available on the Company Websites (as defined below) at
all times during the periods indicated on Schedule 3.27 of the Company
Disclosure Letter. The Company's privacy practices conform, and at all times
have conformed, in all material respects to its privacy policy. The Company has
complied with all Applicable Laws relating to (a) the privacy of users of the
Company's products and services and all Internet websites owned, maintained or
operated by the Company (the "Company Websites"), and (b) the collection,
storage and transfer of any personally identifiable information collected by the
Company or by third parties having authorized access to the Company's records.
The Company's privacy policy conforms, and at all times has conformed, in all
material respects with all of the Company's contractual commitments to its
customers and the viewers of the Company Websites. Each of the Company Websites
and all materials distributed or marketed by the Company have at all times made
all disclosures to users or customers required by Applicable Laws, and none of
such disclosures made or contained in any Company Website or in any such
materials have been inaccurate, misleading or deceptive or in violation of any
Applicable Law.

     3.28 Information Statement. None of the information to be delivered to the
Company Stockholders in connection with this Agreement (other than information
regarding Acquirer which was delivered by Acquirer to the Company in connection
with this Agreement) contains


                                       43

together, contains any untrue statement of a material fact or omits to state any
material fact necessary in order to make the statements contained herein and
therein, in light of the circumstances under which such statements were made,

or, to Acquirer's knowledge, investigation pending, or, to Acquirer's knowledge,
threatened against Acquirer or any of its Subsidiaries or any of their
respective officers of directors (in their capacities as such) before any
agency, court or tribunal that is reasonably likely to succeed on its merits and
if determined adversely to Acquirer or any of its Subsidiaries or any of their
respective officers of directors (in their capacities as such) would have a
Material Adverse Effect on Acquirer. There is no judgment, decree or order
outstanding against Acquirer or any of its Subsidiaries that would reasonably be
expected to prevent, enjoin or materially alter or delay any of the transactions
contemplated by this Agreement or that would reasonably be expected to have a
Material Adverse Effect on Acquirer.

organization immediately prior to, but conditioned upon, the Effective Time and
(b) any and all group severance, separation, retention and salary continuation
plans, programs or arrangements (other than agreements entered into by certain
individuals to effect transactions contemplated by this Agreement) prior to, but
conditioned upon, the Closing.

          5.10.2 Following the Effective Time, those Company employees who
continue as employees of Acquirer after the Closing (each, a "Continuing
Employee") will be entitled to participate in Acquirer's employee benefit plans
commensurate with his or her position with Acquirer in accordance with
Acquirer's standard policies in effect from time to time and on terms no less
favorable than those offered by Acquirer to employees of Acquirer in accordance
with the eligibility criteria thereof. To the extent permitted by Applicable
Law, each Continuing Employee shall receive full credit for years of service
with the Company prior to the Effective Time for purposes of determining
eligibility to participate and vesting under any applicable Acquirer employee
benefit plan; provided, however, that, except for the amount of vacation pay
accruable by any such Continuing Employee for periods from and after the
Effective Time, such service with the Company shall not be used in calculating
the amount of any such benefit. All pre-existing health condition limitations,
exclusions and eligibility waiting periods under any group health plans shall be
waived with respect to such Continuing Employees, except limitations or waiting
periods already in effect with respect to one or more Continuing Employees which
had not been satisfied as of the Effective Time under any welfare plan
maintained for such Continuing Employee immediately prior to the Effective Time.
To the extent permitted by Acquirer's welfare benefit carriers and with respect
to each welfare benefit plan of Acquirer in which a Continuing Employee is
entitled to participate, (a) the outstanding claims and expenses incurred by
such Continuing Employee under the corresponding welfare benefit plan of the
Company for the portion of the plan year preceding the Effective Time shall be
recognized and (b) such Continuing Employee shall be given credit for amounts
paid by him or her under the corresponding welfare benefit plan of the Company
for the portion of the plan year preceding the Effective Time for purposes of
applying deductibles, co-payments and out-of-pocket maximums as though such
amounts had been paid in accordance with the terms and conditions of the
corresponding welfare benefit plan of Acquirer. Subject to compliance with the
requirements of Acquirer's 2001 Employee Stock Purchase Plan (the "ESPP"), the
Continuing Employees shall be permitted to participate in the ESPP commencing on
the first enrollment date following the Effective Time.

     5.11 Information Statement. The Company shall deliver to Acquirer's legal
counsel a draft of an information statement, in the form requested and provided

considering and approving the Merger, this Agreement, the Company Ancillary
Agreements and the transactions contemplated hereby and thereby.

     5.12 Approval of the Company Stockholders.

          5.12.1 Promptly after the Agreement Date, the Company shall take all
action necessary in accordance with this Agreement, the Delaware Law, the
California Law, if applicable, and the Certificate of Incorporation and Bylaws
of the Company to obtain the written consent of the Company Stockholders for the
approval and adoption of this Agreement and the


                                       52

<PAGE>

Company Ancillary Agreements and approval of the Merger and the other
transactions contemplated by this Agreement, including the approval of the
Restated Certificate (the "Company Stockholder Approval"). The commencement,
disclosure, announcement or submission to the Company of any Alternative
Transaction or Superior Offer (as defined below) shall not limit the Company's
obligation to call a meeting of the Company Stockholders or solicit the written
consent of the Company Stockholders to obtain the Company Stockholder Approval.

          5.12.2 The Company's Board of Directors shall unanimously recommend
that the Company Stockholders vote in favor of and approve and adopt this
Agreement and the Company Ancillary Agreements and approve the Merger in
connection with obtaining the Company Stockholder Approval. The Information
Statement shall include a statement to the effect that the Board of Directors of
the Company has unanimously recommended that the Company Stockholders vote in
favor of and approve and adopt this Agreement and the Company Ancillary
Agreements and approve the Merger. Except as otherwise provided in Section
5.12.3, neither the Company's Board of Directors nor any committee thereof shall
withdraw, amend or modify, or propose or resolve to withdraw, amend or modify,
in a manner adverse to Acquirer, the recommendation of the Company's Board of
Directors that the Company Stockholders vote in favor of and approve and adopt
this Agreement and the Company Ancillary Agreements and approve the Merger.

          5.12.3 Nothing herein shall prevent the Company's Board of Directors
from withdrawing, amending or modifying its recommendation in favor of the
Merger if (i) a Superior Offer is made to the Company and is not withdrawn, (ii)
the Company shall have provided written notice to Acquirer (a "Notice of
Superior Offer") advising Acquirer that the Company has received a Superior
Offer, specifying all of the material terms and conditions of such Superior
Offer and identifying the person making such Superior Offer, (iii) the Company's
Board of Directors concludes in good faith, after consultation with its outside
legal counsel, that in light of such Superior Offer the withdrawal, amendment or
modification of such recommendation is required in order for the Company's Board
of Directors to comply with its fiduciary obligations to the Company
Stockholders under Applicable Laws, and (iv) the Company shall not have violated
any of the restrictions set forth in Section 5.7. The Company shall provide
Acquirer with at least two business days prior notice of any meeting of the
Company's Board of Directors at which the Company's Board of Directors is
reasonably expected to consider any Alternative Transaction to determine whether
such Alternative Transaction is a Superior Offer. Nothing contained in this
Section 5.12.3 shall limit the Company's obligation to call a meeting of the
Company Stockholders or solicit the written consent of the Company Stockholders
to obtain the Company Stockholder Approval, regardless of whether the
recommendation of the Company's Board of Directors shall have been withdrawn,
amended or modified. "Superior Offer" means an unsolicited, bona fide written
offer made by a third party to consummate any of the following transactions: (i)
a merger or consolidation involving the Company pursuant to which the
stockholders of the Company immediately preceding such transaction hold less
than 50% of the equity interests in the surviving or resulting entity of such
transaction; or (ii) the acquisition by any person (including by way of a tender
offer or an exchange offer or a two-step transaction involving a tender offer
followed with reasonable promptness by a merger involving the Company), directly
or indirectly, of ownership of 100% of the then outstanding shares of Company
Capital Stock, on terms that


                                       53

<PAGE>

the Company's Board of Directors determines, in its reasonable judgment (based
on the written advice of a financial advisor of national standing), to be more
favorable to the Company Stockholders than the terms of the Merger; provided,
however, that any such offer shall not be deemed to be a "Superior Offer" if any
financing required to consummate the transaction contemplated by such offer is
not committed or is not otherwise likely in the reasonable judgment of the
Company's Board of Directors (based on the advice of a financial advisor of
national standing) to be obtained by such third party on a timely basis.

          5.12.4 The Company shall submit any payments or benefits which would
otherwise constitute parachute payments under Section 280G of the Code to
approval by such percentage of the Company's outstanding voting securities as is
required by the terms of Section 280G(b)(5)(B) of the Code to avoid such
parachute payment treatment. Any stockholder approval so obtained by the Company
shall have been obtained in a manner which satisfies all applicable requirements
of Section 280G(b)(5)(B) of the Code and the proposed Treasury Regulations
thereunder, including Q-7 of Section 1.280G-1 of such proposed regulations. In
the absence of such stockholder approval, those payments and benefits shall be
reduced to the maximum dollar amount which would not otherwise result in their
treatment as parachute payments under Section 280G of the Code.

     5.13 Company Plan. Upon Acquirer's request, the Company shall make such
amendments to the Company Plan and the form option agreement and option exercise
agreement under the Company Plan as is requested by Acquirer; provided, however,
that any such amendments shall not have adversely affected the rights of any
holder of outstanding Company Options.

     5.14 New Company Options. The Company shall grant Company Options (the "New
Company Options") to the employees of the Company listed in Schedule 5.14 of the
Company Disclosure Letter (the "New Optionees") in the amounts, having a per
share exercise price and with such vesting schedules and other terms as
specified on Schedule 5.14 of the Company Disclosure Letter. The New Company
Options shall be subject to, and effective immediately prior to, the Effective
Time.

     5.15 Company Warrants and Preferred Rights. The Company shall timely
provide to holders of the Company Warrants and Preferred Rights, in accordance
with the terms thereof, all required notices of the Merger and the transactions
contemplated by this Agreement. The Company shall use its reasonable best
efforts to terminate effective as of the Closing each Company Warrant and each
Preferred Right which has not been exercised.

     5.16 Termination of Investor Documents. The Company shall use its
reasonable best efforts to cause each of (a) the Amended and Restated Voting

Company and certain Company Stockholders (the "Existing Voting Agreement"), (b)

"Eldridge Agreement"), and (f) the Restricted Common Stock Purchase Agreement
dated February 18, 2000 by and between the Company and Nir Zuk (the "Zuk
Agreement" and together with the Loonkar Agreement and the Eldridge Agreement,
the "Restricted Stock Agreements") to be terminated, effective as of the
Closing, in accordance with their respective terms, and the Company shall use
its reasonable best efforts to cause the parties to the Existing Voting
Agreement, the Rights Agreement, the Refusal Agreement and the Restricted Stock
Agreements to waive all of their respective rights thereunder, effective as of,
and contingent upon, the Closing. The Company shall use its reasonable best
efforts to cause the Company Series B Preferred Stock capital call requirement
set forth in the Series B Preferred Stock Purchase Agreement dated January 18,
2001 by and among the Company and the purchasers defined therein to be
terminated, effective as of the Closing.

     5.17 Restated Certificate. Prior to the Closing, (a) the Board of Directors

connection with the Merger.

take all commercially reasonable actions necessary to qualify the Merger as a
"reorganization" under Section 368(a) of the Code. Prior to the Closing, the
Company shall pay in full all of its debts that would prevent the Merger from
qualifying as a "reorganization" under Section 368(a) of the Code, including all
of its debts owing to any Company Stockholder.

     5.20 Employees. The Company shall use all commercially reasonable efforts
to assist Acquirer in securing for employment by Acquirer after the Closing, (a)

          7.2.3 No dividends or distributions payable to holders of record of
shares of Acquirer Common Stock after the Effective Time shall be paid to the
holder of any unsurrendered Company Certificate unless and until the holder of
such unsurrendered Company Certificate surrenders such Company Certificate or an
Affidavit to the Exchange Agent as provided above. Subject to the effect, if
any, of applicable escheat and other laws, following surrender of any Company
Certificate or Affidavit, there shall be delivered to the person entitled
thereto, without interest, the amount of any dividends and distributions
theretofore paid with respect to shares of Acquirer Common Stock so withheld as
of any date subsequent to the Effective Time and prior to such date of delivery.

prior to the Effective Time. If, after the Effective Time, any Company
Certificates or Affidavits are presented for any reason, they shall be cancelled
and exchanged as provided in this Section 7.2.

          7.2.5 Until Company Certificates or an Affidavit representing shares
of Company Stock that are outstanding immediately prior to the Effective Time
are surrendered pursuant to Section 7.2.2, such Company Certificates shall be
deemed, for all purposes, to evidence ownership of the number of shares of
Acquirer Common Stock and the cash amount, if any, into which such shares of
Company Stock shall have been converted pursuant to Section 2.2.2, subject to
the provisions of Section 2.2.4 (regarding cancellation of Company-owned stock),
Section 2.2.5 (regarding the elimination of fractional shares of Acquirer Common
Stock), Section 2.2.6 (regarding the continuation of vesting and repurchase
rights) and Section 2.6 (regarding the withholding of the Escrow Fund).

     7.3 Dissenting Shares. If, in connection with the Merger, holders of
Company Stock are entitled to appraisal rights pursuant to the Delaware Law or,
if applicable, dissenters' rights pursuant to Section 1300 et seq. of the
California Law, any shares of Company Stock held by Company Stockholders who
exercise and perfect such appraisal rights or, if applicable, dissenters' rights
("Dissenting Shares") shall not be converted into a right to receive shares of
Acquirer Common Stock and cash as provided in Section 2.2.2, but shall be
converted into the right to receive such consideration as may be determined to
be due with respect to such Dissenting Shares pursuant to the Delaware Law or,
if applicable, the California Law. The Company shall give Acquirer prompt notice
(and in no event more than two business days) of any demand received by the
Company for appraisal of Company Stock or notice of exercise of a Company
Stockholder's dissenters' rights, and Acquirer shall have the right to control
all negotiations and proceedings with respect to any such demand. The Company
agrees that, except with Acquirer's prior written consent, it shall not
voluntarily make any payment with respect to, or settle or offer to settle, any
such demand for appraisal or exercise of dissenters' rights. In the event that
any Company Stockholder fails to make an effective demand for payment or fails
to perfect his appraisal rights or dissenters' rights or otherwise loses his
status as a holder of Dissenting Shares, Acquirer shall, as of the later of the
Effective Time or ten business

days from the occurrence of such event, issue and deliver, upon surrender by
such Company Stockholder of its Company Certificate or Certificates, the cash
amount, if any, without interest thereon, and the shares of Acquirer Common
Stock which such Company Stockholder would have been entitled under Section
2.2.2, subject to the provisions of Section 2.2.4 (regarding cancellation of
Company-owned stock), Section 2.2.5 (regarding the elimination of fractional
shares of Acquirer Common Stock), Section 2.2.6 (regarding the continuation of
vesting and repurchase rights) and Section 2.6 (regarding the withholding of the
Escrow Fund).

Agreement, the Company Disclosure Letter, any Company Ancillary Agreement or any
certificate delivered by or on behalf of the Company or an officer of the
Company pursuant hereto; (ii) any inaccuracy, misrepresentation or untruth in

in the case of any such inaccuracy, misrepresentation or untruth, the
indemnifying person shall be only the Company Stockholder whose Investment
Representation Letter contained the inaccuracy, misrepresentation or untruth;
(iii) any Unpaid Transaction Expenses to the extent that such Unpaid Transaction
Expenses were not included in the Closing TNW Calculations; (iv) any amounts
paid with respect to Dissenting Shares to the extent that such amounts exceed
the value of the shares of Acquirer Common Stock (valued at the Acquirer Average
Price Per Share) and cash amount, if any, that the holders of such Dissenting
Shares would have received in the Merger pursuant to Section 2.2.2 (such excess
amounts, the "Excess Dissenters' Amounts"); and (v) any increases to the Closing
Reductions as finally determined in accordance with Section 2.2.7 (such

     11.3 Limitations on Indemnification.

          11.3.1 Each Company Stockholder shall severally, and not jointly, but
only to the extent of each Company Stockholder's Pro Rata Share, indemnify and
hold harmless the Acquirer Indemnified Persons. Except for fraud, willful
misrepresentation or willful misconduct or a claim based upon a breach of the
representations and warranties of the Company referred to in Section 2.2.7(a)
(Closing TNW Calculations) and contained in Section 3.4 (Capitalization),
Section 3.7 (Taxes) or Section 3.8 (Company Financial Statements) or a claim
related to title to Company securities as represented in a Company Stockholder's
Investment Representation Letter (for which the particular Company Stockholder
will be the indemnifying person for such claim), and subject to Section 11.10,
no Company Stockholder shall have any liability to an Acquirer Indemnified
Person under this Agreement or its Investment Representation Letter except to
the extent of such Company Stockholder's Pro Rata Share of the Escrow Shares and
any other assets deposited in escrow pursuant to the terms of Section 2.6 and
Article 11. Notwithstanding the foregoing sentence, the aggregate liability of
each Company Stockholder pursuant to Section 11.2 for a claim based upon a
breach of the representations and warranties contained in Section 3.13
(Intellectual Property) shall be limited to such Company Stockholder's Pro Rata
Share of the Escrow Shares and any other assets deposited in escrow pursuant to
the terms of Section 2.6 and Article 11 and such Company Stockholder's Pro Rata
Share of the IP Post-Release Claims in accordance with Section 11.10. The
aggregate liability of each Company Stockholder pursuant to Section 11.2 and
such Company Stockholder's Investment Representation Letter for a claim based
upon a breach of Section 2.2.7(a) (Closing TNW Calculations), Section 3.4
(Capitalization), Section 3.7 (Taxes) or Section 3.8 (Company Financial
Statements) or a claim related to title to Company securities (as represented in
such Company Stockholder's Investment Representation Letter) shall be limited to
the value of the shares of Acquirer Common Stock and cash amount, if any,
received by such Company Stockholder in the Merger. The value of each Escrow
Share shall, for such purposes of satisfying claims for Damages, be deemed to
equal the Acquirer Average Price Per Share, regardless of its actual fair market
value as of the time that a claim for indemnification may be made against such
share. In the event of a Capital Change after the Effective Time, the Acquirer
Average Price Per Share will, for purposes of this Section 11.3.2, be equitably
adjusted.

          11.3.2 The indemnification provided for in Section 11.2 shall not
apply unless and until the aggregate Damages for which one or more Acquirer
Indemnified Persons seeks or has sought indemnification hereunder exceeds a
cumulative aggregate of $250,000 (the "Basket"), in which event the Company
Stockholders shall, subject to the other limitations herein, be liable to
indemnify the Acquirer Indemnified Persons for all Damages; provided, however,
that the Basket shall not apply to (a) any indemnification claim for fraud,
willful misrepresentation or willful misconduct on the part of the Company or a
Company Stockholder, (b) any inaccuracy, misrepresentation or untruth in any
representation or warranty of any Company Stockholder contained such Company
Stockholder's Investment Representation Letter, (c) any Unpaid Transaction
Expenses, (d) any claim based upon a breach of Section 3.8 (Company Financial
Statements), (e) any Excess Dissenters' Amounts, or (f) any TNW Adjustments.
Notwithstanding the foregoing, if Damages for which one or more Acquirer


                                       67

<PAGE>

Indemnified Persons seeks or has sought indemnification hereunder prior to the
Escrow Release Date do not exceed the Basket, but such Damages, together with
Damages directly or indirectly incurred, paid or accrued in connection with,
resulting from or arising out of the IP Post-Release Claims, exceed the Basket,
then the Acquirer Indemnified Persons shall, subject to the applicable
limitations set forth in Sections 11.3.1 and 11.10, be entitled to recover from
the Company Stockholders, according to each Company Stockholder's Pro Rata
Share, all such Damages directly or indirectly incurred, paid or accrued in
connection with, resulting from or arising out of any of the items set forth in
Section 11.2.1; provided, however, that, with respect to clauses (i) and (ii) of
Section 11.2.1, the Acquirer Indemnified Persons shall only be entitled to
recover from the Company Stockholders, according to each Company Stockholder's
Pro Rata Share, Damages directly or indirectly incurred, paid or accrued in
connection with, resulting from or arising out of any inaccuracy,
misrepresentation, breach of, or default in, any of the representations,
warranties or covenants that remain operative and in full force and effect in
accordance with Section 11.1 as of the date that all Damages directly or
indirectly incurred, paid or accrued in connection with, resulting from or
arising out of any of the items set forth in Section 11.2.1 exceed the Basket.

     11.4 Appointment of Representative.

          11.4.1 David Spreng shall act as representative (the "Representative")
of the Company Stockholders and as the attorney-in-fact and agent for and on
behalf of each Company Stockholder with respect to claims for indemnification
under this Article 11 and the matters set forth in Section 2.2.7 and the taking
by the Representative of any and all actions and the making of any decisions
required or permitted to be taken by the Representative under this Agreement,
including the exercise of the power to: (a) authorize the release or delivery to
Acquirer of the Escrow Fund in satisfaction of indemnification claims by
Acquirer or any other Acquirer Indemnified Person pursuant to this Article 11;
(b) agree to, negotiate, enter into settlements and compromises of, demand
arbitration of, and comply with orders of courts and awards of arbitrators with
respect to, any claim for indemnification under this Article 11 or with respect
to the matters set forth in Section 2.2.7; (c) arbitrate, resolve, settle or
compromise any claim for indemnification made pursuant to this Article 11; and
(d) take all actions necessary in the judgment of the Representative for the
accomplishment of the foregoing. The Representative shall have authority and
power to act on behalf of each Company Stockholder with respect to the
disposition, settlement or other handling of all claims under this Article 11
and all rights or obligations arising under this Article 11. The Company
Stockholders shall be bound by all actions taken and documents executed by the
Representative in connection with this Article 11 and Section 2.2.7, and
Acquirer shall be entitled to rely on any action or decision of the
Representative. In performing the functions specified in this Agreement, the
Representative shall not be liable to any Company Stockholder in the absence of
gross negligence or willful misconduct on the part of the Representative. Each
Company Stockholder shall severally, and not jointly, pro rata in proportion to
each Company Stockholder's Pro Rata Share, indemnify and hold harmless the
Representative from and against any loss, liability or expense incurred without
gross negligence or willful misconduct on the part of the Representative and
arising out of or in connection with the acceptance or administration of his
duties hereunder. Any out-of-pocket costs and expenses reasonably incurred by
the Representative in connection with actions taken by the Representative
pursuant to the terms of this Article 11 (including the hiring of legal counsel
and the incurring of legal fees and costs) shall be paid directly by the Company


                                       68

<PAGE>

Stockholders to the Representative based on each Company Stockholder's Pro Rata
Share; no such amounts shall be paid from the Escrow Fund.

          11.4.2 At any time, former Company Stockholders holding at least a
majority of the Escrow Shares shall have the power to appoint a new
Representative by written consent; provided, however, that any such appointment
shall not be effective (a) unless a copy of the written consent appointing such
new Representative is signed by former Company Stockholders holding at least a
majority of the Escrow Shares and delivered to Acquirer and (b) until the later
of the date specified in such written consent or the date such written consent
is received by Acquirer.

     11.5 Notice of Claim. As used herein, the term "Claim" means a claim for
indemnification of Acquirer or any other Acquirer Indemnified Person for Damages
under this Article 11. Subject to the following sentence, Acquirer shall give
notice of any Claim under this Agreement of which it is aware, whether for its
own Damages or for Damages incurred by any other Acquirer Indemnified Person,
and Acquirer shall give written notice of a Claim executed by an officer of
Acquirer (a "Notice of Claim") to the Representative promptly after Acquirer
becomes aware of the existence of any potential Claim by an Acquirer Indemnified
Person for indemnification from the Company Stockholders under this Article 11,
but in any event before the Release Date, arising from or relating to:

          (a) Any item specified in Section 11.2; or

          (b) the assertion, whether orally or in writing, against Acquirer or
any other Acquirer Indemnified Person of a claim, demand, suit, action,
arbitration, investigation, inquiry or proceeding brought by a third party
against Acquirer or such other Acquirer Indemnified Person (in each such case, a
"Third-Party Claim") that is based on, arises out of or relates to any item
specified in Section 11.2.

     Until the Release Date, no delay on the part of Acquirer in giving the
Representative a Notice of Claim shall relieve the Representative or any Company
Stockholder from any of its obligations under this Article 11 unless (and then
only to the extent that) the Representative or the Company Stockholders are
materially prejudiced thereby.

     11.6 Defense of Third-Party Claims.

          11.6.1 Acquirer shall defend any Third-Party Claim, and the costs and
expenses incurred by Acquirer in connection with such defense (including
reasonable attorneys' fees, other professionals' and experts' fees and court or
arbitration costs) shall be included in the Damages for which Acquirer may seek
indemnification pursuant to a Claim made by any Acquirer Indemnified Person
hereunder.

          11.6.2 The Representative shall have the right to receive copies of
all pleadings, notices and communications with respect to the Third-Party Claim
to the extent that receipt of such documents by the Representative does not
affect any privilege relating to the Acquirer Indemnified Person and may
participate in settlement negotiations with respect to the Third-Party Claim. No
Acquirer Indemnified Person shall enter into any settlement of a Third-Party
Claim without the prior written consent of the Representative (which consent
shall


                                       69

<PAGE>

not be unreasonably withheld); provided, however, that if the Representative
shall have consented in writing to any such settlement, then the Representative
shall have been deemed to accept the related Claim by any Acquirer Indemnified
Person for indemnification under Section 11.2 for the amount of such settlement;
and the Company Stockholders shall remain responsible to indemnify the Acquirer
Indemnified Persons for all Damages they may incur arising out of, resulting
from or caused by the Third-Party Claim to the fullest extent provided in this
Article 11.

     11.7 Contents of Notice of Claim. Each Notice of Claim by Acquirer given
pursuant to Section 11.5 shall contain the following information:

          (a) that Acquirer or another Acquirer Indemnified Person has incurred,
paid or properly accrued (in accordance with GAAP) or, in good faith, believes
it shall have to incur, pay or accrue (in accordance with GAAP), Damages in an
aggregate stated amount arising from such Claim (which amount may be the amount
of damages claimed by a third party in an action brought against any Acquirer
Indemnified Person based on alleged facts, which if true, would give rise to
liability for Damages to such Acquirer Indemnified Person under this Article
11); and

          (b) a brief description, in reasonable detail (to the extent
reasonably available to Acquirer), of the facts, circumstances or events giving
rise to the alleged Damages based on Acquirer's good faith belief thereof,
including the identity and address of any third-party claimant (to the extent
reasonably available to Acquirer) and copies of any formal demand or complaint,
the amount of Damages, the date each such item was incurred, paid or properly
accrued, or the basis for such anticipated liability, and the specific nature of
the breach to which such item is related.

     11.8 Resolution of Notice of Claim. Each Notice of Claim given by Acquirer
shall be resolved as follows:

          (a) Uncontested Claims. If, within 30 business days after a Notice of
Claim is received by the Representative, the Representative does not contest
such Notice of Claim in writing to Acquirer as provided in Section 11.8(b), the
Representative shall be conclusively deemed to have consented, on behalf of all
Company Stockholders, to the recovery by the Acquirer Indemnified Person of the
full amount of Damages specified in the Notice of Claim in accordance with this
Article 11, including the forfeiture of the Escrow Fund, and, without further
notice, to have stipulated to the entry of a final judgment for damages against
the Company Stockholders for such amount in any court having jurisdiction over
the matter where venue is proper.

          (b) Contested Claims. If the Representative gives Acquirer written
notice contesting all or any portion of a Notice of Claim (a "Contested Claim")
within the 30 business day period specified in Section 11.8(a), then such
Contested Claim shall be resolved by either (i) a written settlement agreement
executed by Acquirer and the Representative or (ii) in the absence of such a
written settlement agreement, by binding arbitration between Acquirer and the
Representative in accordance with the terms and provisions of Section 11.8(c).


                                       70

<PAGE>

          (c) Arbitration of Contested Claims. Any Contested Claim shall be
submitted to mandatory, final and binding arbitration before J.A.M.S./ENDISPUTE
or its successor ("J.A.M.S.") pursuant to the United States Arbitration Act, 9
U.S.C., Section 1 et seq., and that any such arbitration shall be conducted in
Santa Clara County, California. If J.A.M.S. ceases to provide arbitration
service, then the term "J.A.M.S." shall thereafter mean and refer to the
American Arbitration Association ("AAA"). Either Acquirer or the Representative
may commence the arbitration process called for by this Agreement by filing a
written demand for arbitration with J.A.M.S. and giving a copy of such demand to
each of the other parties to this Agreement. The arbitration shall be conducted
in accordance with the provisions of J.A.M.S' Streamlined Arbitration Rules and
Procedures in effect at the time of filing of the demand for arbitration (or, if
J.A.M.S. then means the AAA, the commercial arbitration rules of the AAA then in
effect), subject to the provisions of this Section 11.8(c). The parties shall
cooperate with J.A.M.S. and with each other in promptly selecting an arbitrator
from J.A.M.S.' panel of neutrals and in scheduling the arbitration proceedings
in order to fulfill the provisions, purposes and intent of this Agreement. The
parties covenant that they shall participate in the arbitration in good faith
and that they shall share in its costs in accordance with this Agreement. The
provisions of this Section 11.8(c) may be enforced by any court of competent
jurisdiction, and the party seeking enforcement shall be entitled to an award of
all costs, fees and expenses, including attorneys' fees, to be paid by the party
against whom enforcement is ordered. Judgment upon the award rendered by the
arbitrator may be entered in any court having competent jurisdiction.

               (i) Payment of Costs. Acquirer, on the one hand, and the Company
Stockholders (through the Representative), on the other hand, shall bear the
expense of deposits and advances required by the arbitrator in equal
proportions, but either party may advance such amounts, subject to recovery as
an addition or offset to any award. The arbitrator shall determine the party who
is the prevailing party and the party who is the non-prevailing party. The
non-prevailing party shall pay all reasonable costs, fees and expenses related
to the arbitration, including reasonable fees and expenses of attorneys,
accountants and other professionals incurred by the prevailing party, the fees
of each arbitrator and the administrative fee of the arbitration proceedings.

               (ii) Burden of Proof. Except as may be otherwise expressly
provided herein, for any Contested Claim submitted to arbitration, the burden of
proof shall be as it would be if the Claim were litigated in a judicial
proceeding governed exclusively by the internal laws of the State of California
applicable to contracts executed and entered into within the State of
California, without regard to the principles of choice of law or conflicts of
law of any jurisdiction.

               (iii) Award. Upon the conclusion of any arbitration proceedings
hereunder, the arbitrator shall render findings of fact and conclusions of law
and a final written arbitration award setting forth the basis and reasons for
any decision reached (the "Final Award") and shall deliver such documents to the
Representative and Acquirer, together with a signed copy of the Final Award.
Subject to the provisions of this Agreement, the Final Award shall constitute a
conclusive determination of all issues in question, binding upon the Company
Stockholders, the Representative and Acquirer, and shall include an affirmative
statement to such effect.


                                       71

<PAGE>

               (iv) Timing. The Representative, Acquirer and the arbitrator
shall conclude each arbitration pursuant to this Section 11.8(c) as promptly as
possible for the Contested Claim being arbitrated.

               (v) Terms of Arbitration. The arbitrator chosen in accordance
with these provisions shall not have the power to alter, amend or otherwise
affect the terms of these arbitration provisions or the provisions of this
Agreement.

               (vi) Exclusive Remedy. Following the Effective Time, except as
specifically otherwise provided in this Agreement, arbitration conducted in
accordance with this Agreement shall be the sole and exclusive means of
resolving any dispute between the parties for any Claim made pursuant to this
Article 11.

     11.9 Distribution of Escrow Fund. Within ten business days after the Escrow
Release Date, Acquirer shall deliver to the Company Stockholders the portion of
the Escrow Fund in excess of the amount of the Escrow Fund necessary to satisfy
any unsatisfied or disputed Claims for Damages specified in any Notice of Claim
delivered to the Representative before the Escrow Release Date. As soon as all
such Claims have been resolved in accordance with this Agreement, Acquirer shall
deliver to the Company Stockholders all remaining portions of the Escrow Fund
not required to satisfy such Claims.

     11.10 Intellectual Property Claims. After the Escrow Release Date and prior
to the three-year anniversary of the Effective Time, the Acquired Indemnified
Persons may make Claims against the Company Stockholders, or any of them, under
Section 11.2 for Damages directly or indirectly incurred, paid or accrued in
connection with, resulting from or arising out of any inaccuracy,
misrepresentation, breach of, or default in, any of the representations,
warranties or covenants given or made by the Company in Section 3.13
(Intellectual Property) (each such Claim, an "IP Post-Release Claim") and,
during such period, each Company Stockholder shall be liable for such IP
Post-Release Claims to the extent of such Company Stockholder's Pro Rata Share
of the value of 7.5% of the Total Consideration (such value, the "IP
Post-Release Claim Limit"); provided, however, that if the amount previously
paid from the Escrow Shares to satisfy any Claims for Damages (collectively, the
"Previous Payments") is greater than the value of 3.75% of the Total
Consideration, then the IP Post-Release Claim Limit shall not be the value of
7.5% of the Total Consideration but instead shall be the difference between (a)
the value of 7.5% of the Total Consideration minus (b) the difference between
(i) the Previous Payments minus (ii) the value of 3.75% of the Total
Consideration. For purposes of this Section 11.10, the percentage value of the
Total Consideration shall be based on the Acquirer Average Price Per Share.

                                   ARTICLE 12
                                  MISCELLANEOUS

     12.1 Governing Law. The internal laws of the State of California,
irrespective of its choice of law principles, shall govern the validity of this
Agreement, the construction of its terms, and the interpretation and enforcement
of the rights and duties of the parties hereto; provided, however, that issues
involving the consummation and effects of the Merger shall be governed by the
laws of the State of Delaware. Subject to the provisions of Section 11.8, all


                                       72

<PAGE>

disputes arising out of this Agreement or the obligations of the parties
hereunder, including disputes that may arise following termination of this
Agreement, shall be subject to the exclusive jurisdiction and venue of the
California State courts of Santa Clara County, California (or, if there is
federal jurisdiction, then the exclusive jurisdiction of the United States
District Court for the Northern District of California with venue in the
division thereof in which Santa Clara County is located). EACH PARTY HEREBY
IRREVOCABLY AND UNCONDITIONALLY CONSENTS TO THE PERSONAL AND EXCLUSIVE
JURISDICTION AND VENUE OF SAID COURTS AND WAIVES TRIAL BY JURY AND ANY OBJECTION
THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING
IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN
INCONVENIENT COURT AND AGREES NOT TO PLEAD OR CLAIM THE SAME.

     12.2 Assignment; Binding Upon Successors and Assigns. No party hereto may
assign any of its rights or obligations hereunder without the prior written
consent of the other parties hereto; provided, however, that Acquirer may assign
this Agreement and the rights and obligation hereunder without consent in
connection with any merger or sale of the portion of its business to which this
Agreement relates. This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns. Any
assignment in violation of this provision shall be void.

     12.3 Severability. If any provision of this Agreement, or the application
thereof, shall for any reason and to any extent be invalid or unenforceable,
then the remainder of this Agreement and the application of such provision to
other persons or circumstances shall be interpreted so as reasonably to effect
the intent of the parties hereto. The parties further agree to replace such void
or unenforceable provision of this Agreement with a valid and enforceable
provision that shall achieve, to the extent possible, the economic, business and
other purposes of the void or unenforceable provision.

     12.4 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original as regards any party whose
signature appears thereon and all of which together shall constitute one and the
same instrument. This Agreement shall become binding when one or more
counterparts hereof, individually or taken together, shall bear the signatures
of all parties reflected hereon as signatories.

     12.5 Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party hereunder shall be deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such party, and the exercise of any one remedy shall not preclude the
exercise of any other. The parties hereto agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to seek an injunction
or injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof in any court of the United States or any state
having jurisdiction.

     12.6 Amendment and Waivers. Any term or provision of this Agreement may be
amended, and the observance of any term of this Agreement may be waived (either
generally or


                                       73

<PAGE>

in a particular instance and either retroactively or prospectively), only by a
writing signed by the party to be bound thereby. The waiver by a party of any
breach hereof or default in the performance hereof shall not be deemed to
constitute a waiver of any other default or any succeeding breach or default.
This Agreement may be amended by the parties hereto as provided in this Section
12.6 at any time before or after approval of this Agreement by the Company
Stockholders, but, after such approval, no amendment shall be made which by any
Applicable Law requires the further approval of the Company Stockholders without
obtaining such further approval; provided, however, that the parties may not
amend Section 6.8 without the approval of a majority of the Company's Board of
Directors as of the Agreement Date. At any time prior to the Effective Time,
each of Company and Acquirer, by action taken by its Board of Directors, may, to
the extent legally allowed, (i) extend the time for the performance of any of
the obligations or other acts of the other, (ii) waive any inaccuracies in the
representations and warranties made to it contained herein or in any document
delivered pursuant hereto, and (iii) waive compliance with any of the agreements
or conditions for its benefit contained herein. No such waiver or extension
shall be effective unless signed in writing by the party against whom such
waiver or extension is asserted. The failure of any party to enforce any of the
provisions hereof shall not be construed to be a waiver of the right of such
party thereafter to enforce such provisions.

     12.7 Expenses. Each party shall bear its respective legal, auditors',
investment bankers', purchaser representatives' and financial advisors' fees and
other expenses incurred with respect to this Agreement, the Merger and the
transactions contemplated hereby ("Transaction Expenses"), and the Company's
Transaction Expenses shall be accrued and accounted for in the Closing TNW
Calculations. Notwithstanding the foregoing, if the Merger is successfully
consummated, then any of the Company's Transaction Expenses not paid on or prior
to the Closing by the Company may be paid by Acquirer and Acquirer shall
thereafter be entitled to indemnification from the Escrow Fund in accordance
with Section 11.2 for an amount equal to the amount of such unpaid Transaction
Expenses (such amount, the "Unpaid Transaction Expenses"), except to the extent
that such Unpaid Transaction Expenses were included in the Closing TNW
Calculations. Whether or not the Merger is consummated, Acquirer shall pay the
costs of the Historical Audits up to $65,000 and such costs up to $65,000 shall
not be included in the Company's Transaction Expenses.

     12.8 Attorneys' Fees. Should suit be brought to enforce or interpret any
part of this Agreement, the prevailing party shall be entitled to recover, as an
element of the costs of suit and not as damages, reasonable attorneys' fees to
be fixed by the court (including costs, expenses and fees on any appeal). The
prevailing party shall be entitled to recover its costs of suit, regardless of
whether such suit proceeds to final judgment.

     12.9 Notices. All notices and other communications required or permitted
under this Agreement shall be in writing and shall be either hand delivered in
person, sent by facsimile, sent by certified or registered first-class mail,
postage pre-paid, or sent by nationally recognized express courier service. Such
notices and other communications shall be effective upon receipt if hand
delivered or sent by facsimile, five days after mailing if sent by mail, and one
day after dispatch if sent by express courier, to the following addresses, or
such other addresses as any party may notify the other parties in accordance
with this Section 12.9:

                          REGISTRATION RIGHTS AGREEMENT

         This Registration Rights Agreement (this "Agreement") is made and
entered into as of September 18, 2002 by and among NetScreen Technologies, Inc.
a Delaware corporation ("Acquirer"), and the individuals and entities listed on
Exhibit A attached hereto (each a "Company Holder" and collectively, the
"Company Holders").

                                    Recitals

         A. This Agreement is entered into pursuant to that certain Agreement
and Plan of Merger dated as of August 22, 2002 (the "Merger Agreement") by and
among Acquirer, Tango Acquisition Corp., a Delaware corporation and a wholly
owned subsidiary of Acquirer ("Merger Sub"), and OneSecure, Inc., a Delaware
corporation (the "Company"). Capitalized terms used but not defined in this
Agreement shall have the meanings given to such terms in the Merger Agreement.

         B. The Merger Agreement provides that, subject to the terms and
conditions of the Merger Agreement, Merger Sub will be merged with Company in a
transaction or series of transactions (the "Merger") in which all outstanding

         C. As an inducement for the Company Holders to approve the Merger
Agreement, the Merger and the transactions contemplated by the Merger Agreement,

         Now, Therefore, in consideration of the foregoing recitals and the

            1.1   Definitions.
                  -----------

                  (a)    Acquirer  Registration  Rights Agreement. The
                         ----------------------------------------
term "Acquirer Registration Rights Agreement" means Acquirer's Fifth Amended and
Restated Registration Rights Agreement dated October 3, 2001 by and among
Acquirer and the Investors (as defined therein).

                  (b)    Existing Registrable Securities.  The term
                         -------------------------------
"Existing Registrable Securities" means the Registrable Securities under in the
Acquirer Registration Rights Agreement.

                  (c)    Registration.  The terms "register,"

"registered," and

<PAGE>

"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act of 1933, as amended
(the "1933 Act"), and the declaration or ordering of effectiveness of such
registration statement.

                           (d)      Registrable Securities.  The term
                                    ----------------------
"Registrable Securities"  means:  (a) shares of Acquirer Common Stock issued to
a Company Holder pursuant to Section 2.2 of the Merger Agreement; and (b) any
shares of Acquirer Common Stock issued as (or issuable upon the conversion or
exercise of any warrant, right, option or other convertible security which is
issued as) a dividend or other distribution with respect to, or in exchange for,
or in replacement of, such shares of Acquirer Common Stock. For purposes of this
Agreement, any Registrable Securities shall cease to be Registrable Securities
when (x) a registration statement covering such Registrable Securities has been
declared effective and such Registrable Securities have been disposed of
pursuant to such effective registration statement, or (y) such Registrable
Securities are sold by a person or entity in a transaction that is exempt from
registration pursuant to Rule 144 under the 1933 Act or a transaction in which
the Company Holders' rights under this Agreement are not assigned. In addition,
the Registrable Securities held by any Company Holder shall cease to be
Registrable Securities on such date on which all of the Registrable Securities
held by such Company Holder can be sold within a period of three months pursuant
to Rule 144 promulgated under the 1933 Act (or any similar provision then in
force).

                         (e)    Form S-3.  The term "Form S-3" means such date
                                --------
form under the 1933 Act as is in effect on the hereof or any successor
registration form under the 1933 Act subsequently adopted by the SEC that
permits inclusion or incorporation of substantial information by reference to
other documents filed by Acquirer with the SEC.

                         (f)    SEC.  The term "SEC" or "Commission" means the
                                ---
U.S. Securities and Exchange Commission.

                   1.2   Piggyback Registrations. Acquirer shall notify all
Company Holders of Registrable Securities in writing at least 30 days prior to
filing any registration statement under the 1933 Act for purposes of effecting a
public offering of securities of Acquirer (including, but not limited to,
registration statements relating to secondary offerings of securities of
Acquirer, but excluding registration statements relating to any registration
under Section 1.3 of this Agreement, any registration under Section 2.2 or 2.4
of the Acquirer Registration Rights Agreement or any employee benefit plan or a
corporate reorganization), and will afford each such Company Holder an
opportunity to include in such registration statement all or any part of the
Registrable Securities then held by such Company Holder. Each Company Holder
desiring to include in any such registration statement all or any part of the
Registrable Securities held by such Company Holder shall, within 20 days after
receipt of the above-described notice from Acquirer, so notify Acquirer in
writing, and in such notice shall inform Acquirer of the number of Registrable
Securities such Company Holder wishes to include in such registration statement.
Notwithstanding any other provision of this Agreement, if Acquirer determines in
good faith that a limitation of the number of shares to be registered is
required, then Acquirer may exclude shares (including Registrable Securities)
from the registration, and the number of shares that may be included in the
registration shall be allocated, first, to Acquirer, and second, to Holders (as
defined in the Acquirer Registration Rights Agreement) exercising rights under
the Acquirer Registration Rights Agreement and Company Holders requesting
inclusion of their Registrable

                                       2

<PAGE>

Securities in such registration statement in such relative proportion as the
number of Existing Registrable Securities then held by the Holders (as defined
in the Acquirer Registration Rights Agreement) or the number of Registrable
Securities then held by the Company Holders, as the case may be, bears to the
total number of Existing Registrable Securities then held by the Holders (as
defined in the Acquirer Registration Rights Agreement) plus the total number of
Registrable Securities then held by the Company Holders provided, however, that
the right of Acquirer to exclude shares (including Registrable Securities) from
the registration as described above shall be restricted so that the aggregate
number of Registrable Securities and Existing Registrable Securities included in
any such registration is not reduced below 25% of the shares included in the
registration. If Acquirer excludes shares from the registration as described in
the preceding sentence, then with respect to the Registrable Securities then
held by any Company Holder who participates in such registration the number of
Registrable Securities to be included in the registration shall be in such
proportion as the number of Registrable Securities then held by such Company
Holder bears to the total number of Registrable Securities then held by all
Company Holders participating in the registration. If a Company Holder does not
include all of its Registrable Securities in any registration statement filed by
Acquirer, such Company Holder shall nevertheless continue to have the right to
include any Registrable Securities in any subsequent registration statement or
registration statements as may be filed by Acquirer with respect to offerings of
its securities, all upon the terms and conditions set forth herein.

                   (a)   Underwriting.   If a registration statement under which
                         ------------
Acquirer gives notice under this Section 1.2 is for an underwritten offering,
then Acquirer shall so advise the Company Holders of Registrable Securities as a
part of the notice referred to in this Section 1.2. In such event, the right of
any such Company Holder's Registrable Securities to be included in a
registration pursuant to this Section 1.2 shall be conditioned upon such Company
Holder's participation in such underwriting and the inclusion of such Company
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Company Holders proposing to distribute their Registrable Securities
through such underwriting shall enter into an underwriting agreement in
customary form with the managing underwriter or underwriter(s) selected for such
underwriting. Notwithstanding any other provision of this Agreement, if Acquirer
or the managing underwriter(s) determines in good faith that a limitation of the
number of shares to be underwritten is required, then Acquirer or the managing
underwriter(s) may exclude shares (including Registrable Securities) from the
registration and the underwriting, and the number of shares that may be included
in the registration and the underwriting shall be allocated, first, to Acquirer,
and second, to Holders (as defined in the Acquirer Registration Rights
Agreement) exercising rights under the Acquirer Registration Rights Agreement
and Company Holders requesting inclusion of their Registrable Securities in such
registration statement in such relative proportion as the number of Existing
Registrable Securities then held by the Holders (as defined in the Acquirer
Registration Rights Agreement) or the number of Registrable Securities then held
by the Company Holders, as the case may be, bears to the total number of
Existing Registrable Securities then held by the Holders (as defined in the
Acquirer Registration Rights Agreement) plus the total number of Registrable
Securities then held by the Company Holders; provided, however, that the right
of the underwriters to exclude shares (including Registrable Securities) from
the registration and underwriting as described above shall be restricted so that
the aggregate number of Registrable Securities and Existing Registrable
Securities included in any such registration is not reduced below 25% of the
shares included in the registration. If any Company

                                       3

<PAGE>

Holder disapproves of the terms of any such underwriting, such Company Holder
may elect to withdraw therefrom by written notice to Acquirer and the managing
underwriter(s), delivered at least ten business days prior to the effective date
of the registration statement. Any Registrable Securities excluded or withdrawn
from such underwriting shall be excluded and withdrawn from the registration.

                       (b)   Expenses.  All expenses incurred in connection
                             --------
with the first three registrations pursuant to this Section 1.2 (excluding
underwriters' and brokers' discounts and commissions), including, without
limitation, all federal and "blue sky" registration and qualification fees,
printers' and accounting fees, and fees and disbursements of counsel for
Acquirer, shall be borne by Acquirer. All expenses incurred in connection with
subsequent registrations pursuant to this Section 1.2 shall be borne by the
Company Holders and Holders (as defined in the Acquirer Registration Rights
Agreement) who participate in such registration on a pro rata basis, and by
Acquirer on a pro rata basis if it includes shares in such registration,
according to the number of Registrable Securities or Existing Registrable
Securities then held by the Company Holders and Holders (as defined in the
Acquirer Registration Rights Agreement), respectively, who participate in such
registration and the number of shares offered by Acquirer that are included in
such registration at the time of its effectiveness.

                  1.3  Form S-3 Registration. If Acquirer receives from any
Company Holder or Company Holders of at least 10% of all Registrable Securities
then outstanding a written request or requests that Acquirer effect a
registration on Form S-3 and any related qualification or compliance, then
Acquirer will:

                       (a)   Notice.  Promptly give written notice of the
                             ------
proposed registration and the Company Holder's or Company Holders' request
therefor, and any related qualification or compliance, to all other Company
Holders of Registrable Securities. Each Company Holder desiring to include in
any such registration statement all or any part of the Registrable Securities
held by such Company Holder shall, within 20 days after receipt of the
above-described notice from Acquirer, so notify Acquirer in writing, and in such
notice shall inform Acquirer of the maximum number of Registrable Securities
such Company Holder wishes to include in such registration statement.

                       (b)   Registration.  As soon as practicable, effect such
                             ------------
registration and all such qualifications and compliances as may be so requested
and as would permit or facilitate the sale and distribution of up to 70%
(excluding any shares of Acquirer Common Stock in the Escrow Fund) of the
Registrable Securities originally issued pursuant to Section 2.2 of the Merger
Agreement. The number of Registrable Securities of each Company Holder included
in such registration shall be allocated on a pro rata basis based on the total
number of Registrable Securities requested to be included in such registration
by the requesting Company Holders and the Company Holders joining in such
request as specified in a written request given within 20 days after receipt of
such written notice from Acquirer; provided, however, that Acquirer shall not be
obligated to effect any such registration, qualification or compliance pursuant
to this Section 1.3:

                             (i)    if Form S-3 is not available for such
offering by the Company Holders;

                                        4

<PAGE>

                             (ii)    if the Company Holders, together with the
holders of any other securities of Acquirer entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) at an aggregate price to the public of less than $1,000,000;

                             (iii)   if Acquirer shall furnish to the Company
Holders a certificate signed by the President or Chief Executive Officer of
Acquirer stating that in the good faith judgment of the Board of Directors of
Acquirer, it would be seriously detrimental to Acquirer or its business for such
Form S-3 registration to be effected at such time or, if such Form S-3
registration has already been effected, for resales of Registrable Securities to
be made pursuant to such Form S-3 registration statement (provided that the
existence or filing of any other registration statement shall not, in and of
itself, cause the the effectiveness of the Company Holders' Form S-3
registration, or resales thereunder, to be determined to be seriously
detrimental to Acquirer or its business), in which event Acquirer shall have the
right to defer the filing of the Form S-3 registration statement no more than
once during any 12-month period for a period of not more than 120 days after
receipt of the request of the Company Holder or Company Holders under this
Section 1.3 or the use of the Form S-3 registration statement and the prospectus
related thereto will be deferred or suspended and will not recommence until (A)
the Company Holders receive from Acquirer copies of the supplemented or amended
prospectus related to the registration statement or (B) the Company Holders are
advised in writing by Acquirer that the prospectus related to the registration
statement may be used, as applicable; provided, however, that if Acquirer shall
so delay the filing of a registration statement, it shall promptly notify the
applicable Company Holders of such determination, and such Company Holders shall
have the right to withdraw the relevant request for registration, in which case
such registration shall not count towards the limit set forth in Section
1.3(b)(iv); provided, further, that if Acquirer shall so defer or suspend the
use of the Form S-3 registration statement and the prospectus related thereto,
it shall use its commercially reasonable efforts to ensure that the use of the
registration statement and the prospectus related thereto may be resumed as soon
as practicable;

                             (iv)    if Acquirer has already effected one
registration on Form S-3 for the Company Holders pursuant to this Section 1.3;

                             (v)     if Acquirer is acquired and shares of
Acquirer Common Stock cease to be publicly traded;

                             (vi)    if the SEC refuses to declare such
registration statement effective due to the participation of any particular
Company Holder in such registration (unless such Company Holder withdraws all
such Company Holder's Registrable Securities from such registration) or if the
manner in which any Registrable Securities are disposed of pursuant to the Form
S-3 registration statement is not included within the plan of distribution set
forth in the prospectus for the Form S-3 registration statement; or

                             (vii)   in any particular jurisdiction in which
Acquirer would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or
compliance.

                                       5

<PAGE>

Subject to the foregoing, Acquirer shall file a Form S-3 registration statement
covering the Registrable Securities and other securities so requested to be
registered pursuant to this Section 1.3 as soon as practicable, and in any event
no later than 90 days, after receipt of the request or requests of the Company
Holders for such registration. Pursuant to the terms of the Acquirer
Registration Rights Agreement, the Holders (as defined therein) are entitled to
receive 30 days notice of such S-3 registration and will be entitled to exercise
piggyback registrations rights to include shares of their Existing Registrable
Securities in such S-3 registration to the extent available under the Acquirer
Registration Rights Agreement.

                       (c)   Expenses.  Acquirer shall pay all expenses
                             --------
incurred in connection with the registration requested pursuant to this Section
1.3 (excluding underwriters' or brokers' discounts and commissions), including,
without limitation, all filing, registration and qualification, printers' and
accounting fees and the reasonable fees and disbursements of one (1) counsel for
selling Company Holder or Company Holders and counsel for Acquirer. Each Company
Holder participating in such registration shall bear such Company Holder's
proportionate share (based on the number of shares sold by such Company Holder
over the total number of shares included in such registration at the time it
goes effective) of all discounts, commissions or other amounts payable to
underwriters or brokers in connection with such offering.

                       (d)   Manner of Sales. Any sale of Registrable
                             ---------------
Securities pursuant to a registration effected pursuant to this Section 1.3 may
only be made in accordance with the method or methods of distribution of such
Registrable Securities that are described in the registration statement for the
registration and permitted by such form of registration statement.

                       (e)   No  Underwritings.  No sale of Registrable
                             -----------------
Securities pursuant to any registration effected pursuant to this Section 1.3
may be effected pursuant to any underwritten offering without Acquirer's prior
written consent, which consent will not be unreasonably withheld.

                 1.4   Obligations of Acquirer.  Whenever required to effect the
                       -----------------------
registration of any Registrable Securities under this Agreement, Acquirer shall,
as expeditiously possible:

                       (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 keep such
registration statement effective until such Company Holders can sell all their
Registrable Securities within a three-month period without registration under
the 1933 Act pursuant to Rule 144.

                       (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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                       (c)   Furnish to the Company Holders such number of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the 1933 Act, and such other documents as they may
reasonably request in order to facilitate the

                                       6

<PAGE>

disposition of the Registrable Securities owned by them that are included in
such registration.

                       (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
Company Holders, provided that Acquirer 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(s) of such offering. Each
Company Holder participating in such underwriting shall also enter into and
perform its obligations under such an agreement.

                       (f)   Notify each Company Holder of Registrable
Securities covered by such registration statement at any time when a prospectus
relating thereto is required to be delivered under the 1933 Act of 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.

                       (g)   Furnish, at the request of any Company Holder
requesting registration of Registrable Securities, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such
securities are being sold through underwriters, or, if such securities are not
being sold through underwriters, on the date that the registration statement
with respect to such securities becomes effective, (i) an opinion, dated as of
such date, of the counsel representing Acquirer for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering and reasonably satisfactory to a majority in
interest of the Company Holders requesting registration, addressed to the
underwriters, if any, and to the Company Holders requesting registration of
Registrable Securities and (ii) a "comfort" letter, dated as of such date, from
the independent certified public accountants of Acquirer, in form and substance
as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering and reasonably satisfactory to a
majority in interest of the Company Holders requesting registration, addressed
to the underwriters, if any, and to the Company Holders requesting registration
of Registrable Securities.

                  1.5  Furnish Information. It shall be a condition precedent to
the obligations of Acquirer to take any action pursuant to Section 1.2 or 1.3
that the selling Company Holders shall furnish to Acquirer such information
regarding themselves and the Registrable Securities held by them, and the
intended method of disposition of such securities, as shall be reasonably
required to timely effect the registration of their Registrable Securities.

                  1.6  Delay of Registration. No Company Holder shall have any
right to obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

                  1.7  Indemnification.  In the event any Registrable Securities
are included in a registration statement under Section 1.2 or 1.3.

                       (a)   By Acquirer.  To the extent permitted by law,
                             -----------
Acquirer will indemnify and hold harmless each Company Holder, the partners,
members, managers, officers and directors of each Company Holder, any
underwriter (as defined in the 1933 Act) for such Company Holder, each of their
respective representatives and agents and such Company Holder's legal counsel
and independent accountants, and each person, if any, who controls such Company
Holder or underwriter within the meaning of the 1933 Act or the Securities
Exchange Act of 1934, as amended ("1934 Act"), against any and all losses,
claims, damages, or liabilities to which they may become subject under the 1933
Act, the l934 Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any of the following statements, omissions or violations (each of the
following being a "Violation"):

                             (i)     any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein, offering
circular, or other document or any amendments or supplements thereto incident to
any such registration, qualification or compliance;

                             (ii)    the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the
statements therein not misleading, or

                             (iii)   any violation or alleged violation by
Acquirer of the 1933 Act, the 1934 Act, any federal or state securities law
or any rule or regulation promulgated under the 1933 Act, the 1934 Act or any
federal or state securities law in connection with any action or inaction by
Acquirer in connection with the offering covered by such registration statement;

and Acquirer will reimburse each such Company Holder, partner, members,
managers, officer or director, each of their respective representatives and
agents and such Company Holder's legal counsel and independent accountants,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating, preparing or
defending any such loss, claim, damage, liability or action; provided however,
that the indemnity agreement contained in this subsection 1.7(a) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of Acquirer (which
consent shall not be unreasonably withheld or delayed), nor shall Acquirer be
liable in any such case for any such loss, claim, damage, liability or action to
the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by such Company Holder, partner,
members, managers, officer, director, representative, agent, legal counsel,
independent accountant, underwriter or controlling person of such Company
Holder.

                       (b)   By Selling Company  Holders.  To the extent
                             ---------------------------
permitted by law, each selling Company Holder, severally but not jointly, if
Registrable Securities held by such Company Holder are included in the
securities as to which such registration, qualification or compliance is being
effected, will indemnify and hold harmless Acquirer, each of its directors, each
of its officers who have signed the registration statement, each person, if any,
who controls

                                       8

<PAGE>

Acquirer within the meaning of the 1933 Act, any underwriter and any other
Company Holder selling securities under such registration statement or any of
such other Company Holder's partners, members, managers, directors or officers,
each of their respective representatives and agents and such Company Holder's
legal counsel and independent accountants, or any person who controls such
Company Holder within the meaning of the 1933 Act or the 1934 Act, against any
and all losses, claims, damages or liabilities (joint or several) to which they
may become subject under the 1933 Act, the 1934 Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any Violation under subsection
1.7(a)(i) or (ii), in each case to the extent (and only to the extent) that such
Violation under subsection 1.7(a)(i) or (ii) occurs in reliance upon and in
conformity with written information furnished by such Company Holder expressly
for use in connection with such registration; and each such Company Holder will
reimburse any legal or other expenses reasonably incurred by Acquirer or any
such director, officer, controlling person, underwriter or other Company Holder,
partner, members, managers, director, officer, representative, agent, legal
counsel, independent accountant or controlling person of such other Company
Holder in connection with investigating, preparing or defending any such loss,
claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this subsection 1.7(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company Holder (which consent
shall not be unreasonably withheld); and provided further, that the total
amounts payable in indemnity by a Company Holder under this Section 1.7(b) in
respect of any Violation under subsection 1.7(a)(i) or (ii) shall not exceed the
net proceeds received by such Company Holder in the registered offering out of
which such Violation under subsection 1.7(a)(i) or (ii) arises.

          (c)  Notice. Promptly after receipt by an indemnified party under this
Section 1.7 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.7, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own 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 conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure of any
indemnified party to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action, only if such failure is
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.7, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.7. 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
of such claim or litigation.

            (d)   Defect Eliminated in Final Prospectus. The foregoing indemnity
agreements of Acquirer and the Company Holders are subject to the condition
that, insofar as they relate to any Violation made in a preliminary prospectus
but eliminated or remedied in the amended prospectus on file with the SEC at the
time the registration statement in question becomes effective or the amended
prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "Final
Prospectus"), such indemnity agreement shall not inure to the benefit of any
person or entity if a copy of the Final Prospectus was furnished to the
indemnified party and was not furnished to the person or entity asserting the
loss, claim, damage or liability at or prior to the time such action is required
by the 1933 Act.

            (e)   Contribution. In order to provide for just and equitable
contribution to joint liability under the 1933 Act in any case in which either
(i) any Company Holder exercising rights under this Agreement, or any
controlling person of any such Company Holder, makes a claim for indemnification
pursuant to this Section 1.7 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 1.7 provides for indemnification in such case, or (ii) contribution
may be required on the part of Acquirer and any such selling Company Holder or
any such controlling person in circumstances for which indemnification is
provided under this Section 1.7; then, and in each such case, such indemnifying
party will contribute to the aggregate losses, claims, damages or liabilities to
which they may be subject (after contribution from others) (i) in such
proportion so that such Company Holder is responsible for the portion
represented by the percentage that the public offering price of its Registrable
Securities offered by and sold under the registration statement bears to the
public offering price of all securities offered by and sold under such
registration statement, and Acquirer and other selling Company Holders are
responsible for the remaining portion or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of Acquirer and the Company Holders in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of Acquirer and of the Company Holders shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by Acquirer or by the Company
Holders and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company
Holders' respective obligations to contribute pursuant to this Section 1.7(e)
are several in proportion to the respective number of Registrable Securities
they sell in the offering as to which such Violation relates, and not joint. No
such Company Holder will be required to contribute any amount in excess of the
public offering price of all such Registrable Securities offered and sold by
such Company Holder pursuant to such registration statement; and no person or
entity guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation.

            (f)   Survival. The obligations of Acquirer and the Company Holders
under this Section 1.7 shall survive the completion of any offering of
Registrable Securities in a

                                       10

<PAGE>

registration statement, and otherwise.

            1.8   Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
Acquirer, Acquirer agrees to:

                  (a)  Make and keep public information available, as those
terms are understood and defined in Rule 144 under the 1933 Act, at all times
after the effective date of the first registration under the 1933 Act filed by
Acquirer for an offering of its securities to the general public;

                  (b)  Use its best efforts to file with the Commission in a
timely manner all reports and other documents required of Acquirer under the
1933 Act and the 1934 Act; and

                  (c)  So long as a Company Holder owns any Registrable
Securities, to furnish to the Company Holder forthwith upon request a written
statement by Acquirer as to its compliance with the reporting requirements of
said Rule 144, and of the 1933 Act and the 1934 Act, a copy of the most recent
annual or quarterly report of Acquirer, and such other reports and documents of
Acquirer as a Company Holder may reasonably request in availing itself of any
rule or regulation of the Commission allowing a Company Holder to sell any such
securities without registration.

            1.9   Termination of Acquirer's Obligations. Acquirer shall have no
obligations pursuant to Section 1.2 or 1.3 with respect to any Registrable
Securities proposed to be sold by a Company Holder in a registration pursuant to
Section 1.2 or 1.3 if, in the opinion of counsel to Acquirer, all such
Registrable Securities proposed to be sold by a Company Holder may be sold in a
three-month period without registration under the 1933 Act pursuant to Rule 144.

       2.   Assignment and Amendment.

            2.1   Assignment. Notwithstanding anything herein to the contrary:

                  (a)  Registration Rights; Refusal Rights. The registration
rights of a Company Holder under Section 1 hereof may be assigned only to an
affiliate or a party who acquires at least 120,000 shares of Registrable
Securities; provided, however, that no party may be assigned any of the
foregoing rights unless Acquirer is given written notice by the assigning party
at the time of such assignment stating the name and address of the assignee and
identifying the securities of Acquirer as to which the rights in question are
being assigned; and provided further that any such assignee shall receive such
assigned rights subject to all the terms and conditions of this Agreement,
including, without limitation, the provisions of this Section 2.

                  (b)  Aggregation.  Shares of Acquirer Common  Stock owned by
Company Holders which are partnerships, limited liability companies,
corporations and other entities having substantially common ownership interests
or managed by the same principals or investment advisors or owned by individual
investors affiliated with one another ("Affiliated Investors") shall be
aggregated for the purposes of this Agreement, and, notwithstanding

                                       11

<PAGE>

anything to the contrary contained in this Agreement, all rights granted to the
Company Holders pursuant to this Agreement may be assigned between Affiliated
Investors.

            2.2   Amendment of Rights. Any provision of this Agreement may be
amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively) only with the
written consent of Acquirer and Company Holders (and/or any of their permitted
successors or assigns) holding shares of Acquirer Common Stock representing 66
2/3% of all the Registrable Securities; provided, however, that any amendment
that directly or indirectly (together with any transaction entered into in
connection therewith) treats any Company Holder or Company Holders in an adverse
manner that is different than any other Company Holder will require the approval
of the Company Holders of a majority of the Registrable Securities then held by
such adversely treated Company Holders. Any amendment or waiver effected in
accordance with this Section 2.2 shall be binding upon each Company Holder
and/or any of their permitted successors or assigns and Acquirer.

            3.    Miscellaneous.

                  3.1  Notices. Any and all notices required or permitted to be

express overnight courier for United States deliveries, or three business days
after such deposit for deliveries outside of the United States, with proof of
delivery from the courier requested; or (iii) three business days after deposit
in the United States mail by certified mail (return receipt requested) for

                       (b)  if to Acquirer, marked "Attention: President", at
350 Oakmead Parkway, Sunnyvale, California 94085.

                  3.2  Entire Agreement. This Agreement, together with all the
Exhibits hereto, and the Merger Agreement, constitute and contain the entire
agreement and understanding of the parties with respect to the subject matter
hereof and supersede any and all prior negotiations, correspondence, agreements,
understandings, duties or obligations between the parties respecting the subject
matter hereof.

                  3.3  Governing Law. This Agreement shall be governed by and

of law. All disputes arising out of this Agreement or the obligations of the
parties hereunder, including disputes that may arise following termination of
this Agreement, shall be subject to the exclusive jurisdiction and venue of the
California State courts of Santa Clara County, California (or, if there is
federal jurisdiction, then the exclusive jurisdiction of the United States
District Court for the Northern District of California with venue in the
division thereof in which Santa Clara County is located).

                  3.4  Severability. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, then such provision(s) shall
be excluded from this Agreement and the balance of this Agreement shall be
interpreted as if such provision(s) were so excluded and shall be enforceable in
accordance with its terms.

                  3.5  Third Parties. Nothing in this Agreement, express or
implied, is intended to confer upon any person or entity, other than the parties
hereto and their successors and assigns, any rights or remedies under or by
reason of this Agreement.

                  3.6  Successors And Assigns. Subject to the provisions of
Section 2.1, the provisions of this Agreement shall inure to the benefit of, and
shall be binding upon, the successors and permitted assigns of the parties
hereto.

                  3.7  Captions. The captions to sections of this Agreement have

suit or other proceeding is instituted concerning or arising out of this
Agreement or any transaction contemplated hereunder, the prevailing party shall

action, suit or other proceeding, including any and all appeals or petitions
therefrom.

                  3.10 Adjustments for Stock Splits, Etc. Wherever in this
Agreement there is a reference to a specific number of shares of Acquirer Common
Stock, then, upon the occurrence of any subdivision, combination or stock
dividend of such stock occurring after the date of this Agreement, the specific
number of shares so referenced in this Agreement shall automatically be
proportionally adjusted to reflect the affect on the outstanding shares of such
stock by such subdivision, combination or stock dividend.

                  3.11 Waiver of Jury Trial. Each party hereto hereby waives its
rights to a jury trial of any claim or cause of action based upon or arising out
of this Agreement or the subject matter hereof. The scope of this waiver is
intended to be all-compassing of any and all disputes that may be filed in any

these provisions shall not be subject to any exceptions. Each party hereto
hereby further represents and warrants that such party has reviewed this waiver
with its legal counsel, and that such party knowingly and voluntarily waives its
jury trial rights following consultation with legal counsel. This waiver is
irrevocable, meaning that it may not be modified either orally or in writing,
and this waiver shall apply to any subsequent amendments, supplements or
modifications to (or assignments of) this Agreement. In the event of litigation,
this Agreement may be filed as a written consent to a trial (without a jury) by
the court.
