        The Company hereby represents and warrants to each Investor that, except
as set forth on a Schedule of Exceptions attached hereto as Exhibit B,
specifically identifying the relevant subparagraph(s) hereof, which exceptions
shall be deemed to be representations and warranties as if made hereunder:

Refusal and Co-Sale Agreement, and the Restated Certificate. The Company is duly
qualified and is authorized to transact business and is in good standing as a

the Company.

Preferred Stock has been taken or will be taken prior to the Closing, and this
Agreement, the Amended and Restated Investors' Rights Agreement, and the Amended
and Restated Right of First Refusal and Co-Sale Agreement, when executed and
delivered, will constitute valid and legally binding obligations of the Company,
enforceable in accordance with their respective terms except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of
general application affecting enforcement of creditors' rights generally, (ii)
as limited by laws relating to the availability of specific performance,
injunctive relief, or other equitable remedies, and (iii) to the extent that the
indemnification provisions contained in the Amended and Restated Investors'
Rights Agreement may be limited by applicable laws.

        2.3 VALID ISSUANCE OF PREFERRED AND COMMON STOCK. The Series B Preferred
Stock that is being purchased by the Investors hereunder, when issued, sold, and

Company will consist, immediately prior to the Closing, of:

               (a) Preferred Stock. 50,000,000 shares of Preferred Stock, $0.001
par value, of which 5,800,000 have been designated Series A Preferred Stock, of
which 5,771,679 are issued and outstanding and convertible into 17,315,037
shares of Common Stock, and 12,861,500 which have been designated Series B
Preferred Stock, none of which shall be outstanding prior to the First Closing,
and up to all of which shall be outstanding immediately following the Second
Closing. The rights, privileges and preferences of the Series A Preferred Stock
and Series B Preferred Stock are as stated in the Restated Certificate.

               (b) Common Stock. 100,000,000 shares of common stock, $0.001 par
value ("Common Stock"), of which 31,707,379 shares are issued and outstanding.

               (c) Immediately following the Closing, all issued and outstanding
shares of Series A Preferred Stock, Series B Preferred Stock and Common Stock
have been or will be duly authorized and validly issued, have been or will be

of the Series A Preferred Stock and the Series B Preferred Stock or (ii) as
otherwise disclosed on Schedule 2.4, there are not outstanding any options,
warrants, rights (including conversion or preemptive rights and rights of first
refusal), or agreements of any kind for the purchase or acquisition from the
Company of any of its securities. The Company has reserved 12,500,000 shares of
its Common Stock for purchase upon exercise of options and/or rights to purchase
to be granted in the future under the Company's 1999 Incentive Stock Option,
Nonqualified Stock Option and Restricted Stock Plan (the "1999 Plan"). Except as

agreement or understanding, and, to the best of the Company's knowledge, there
is no agreement or understanding between any persons that affects or relates to
the voting or giving of written consents with respect to any security or the
voting by a director of the Company.

               (d) Schedule 2.4 sets forth a true, complete and correct list of
the holders of record of the Company's Common Stock and Series A Preferred
Stock, which list shall identify the name and address of each such holder and
the number of shares of Common and/or Series A Preferred Stock held by each such
holder. Schedule 2.4 also sets forth a true, complete and correct list of the
holders of record of the Company's outstanding warrants, options and other
rights to purchase or subscribe for shares of Common Stock or Preferred Stock.

        2.5 COMPLIANCE WITH OTHER INSTRUMENTS. The Company is not in violation
or default (i) of any provision of its Amended and Restated Certificate of
Incorporation, as amended or Bylaws, as amended (ii) of any provision of any
mortgage, indenture, agreement, instrument, or contract to which it is a party
or by which it is bound, except where such violation or default would not have a
material adverse effect on the Company, or (iii) to the best of its knowledge,
of any federal or state, statute, rule, regulation or restriction. The
execution, delivery, and performance by the Company of this Agreement, the
Amended and Restated Investors' Rights Agreement, and the Amended and Restated
Right of First Refusal and Co-Sale Agreement, and the consummation of the
transactions

                                       3
<PAGE>   4

contemplated hereby and thereby, will not result in any such violation or be in
material conflict with or constitute, with or without the passage of time or
giving of notice, either a material default under any such provision or an event
that results in the creation of any material lien, charge, or encumbrance upon
any assets of the Company or the suspension, revocation, impairment, forfeiture,
or nonrenewal of any material permit, license, authorization, or approval
applicable to the Company, its business or operations, or any of its assets or
properties.

        2.6 GOVERNMENTAL CONSENTS. No consent, approval, qualification, order or
authorization of, or filing with, any local, state, or federal governmental
authority is required on the part of the Company in connection with the
Company's valid execution, delivery, or performance of this Agreement, the
offer, sale or issuance of the Series B Preferred Stock by the Company, or the
issuance of Common Stock upon conversion of the Series B Preferred Stock, except
(i) the filing of the Restated Certificate with the Secretary of State of the
State of Delaware, and (ii) such filings as have been made prior to the Closing,
except any post-closing filings as may be required under applicable state
securities laws, which will be timely filed within the applicable periods
therefor. The Company has not offered shares of its Series B Preferred Stock or
any substantially similar securities of the Company for sale to, or solicited
any offers to buy from, or otherwise approached or negotiated in respect thereof
with, any person other than the Investors, and the Company will not take any
action that will cause the issuance and delivery of the shares of its Series B
Preferred Stock as contemplated hereby to constitute a violation of the
Securities Act or the California Corporate Securities Law of 1968, as amended
(the "California Securities Law").

        2.7 SUBSIDIARIES. The Company does not own or control, directly or
indirectly, any interest in any other corporation, partnership, limited
liability company, association, or other business entity. The Company is not a
participant in any joint venture, partnership, or similar arrangement.

        2.8 CONTRACTS AND OTHER COMMITMENTS. Except as set forth on Schedule
2.8, the Company does not have and is not bound by any contract, agreement,
lease, or other commitment, written or oral, absolute or contingent, other than
(i) contracts for the purchase of supplies and services that were entered into
in the ordinary course of business and that do not involve more than $50,000,
(ii) sales or services contracts entered into in the ordinary course of business
and that do not involve more than $50,000, (iii) contracts terminable at will by
the Company on no more than thirty (30) days' notice without material cost or
liability to the Company and (iv) contracts that are not material to the conduct
of the Company's business. All contracts, agreements and instruments to which
the Company is a party are valid, binding, and in full force and effect, without
any material breach by the Company or, to the best of the Company's knowledge,
any other party thereto and are enforceable by the Company in accordance with
their terms.

        2.9 RELATED-PARTY TRANSACTIONS. Except as set forth on Schedule 2.9, no
employee, officer, stockholder or director of the Company or member of his or
her immediate family is indebted to the Company, nor is the Company indebted (or
committed to make loans or extend or guarantee credit) to any of them, other
than (i) for payment of salary for services rendered, (ii) reimbursement for
reasonable expenses incurred on behalf of the Company, and (iii) for other
standard employee benefits made generally available to all employees including
stock option agreements outstanding under any stock option plan approved by the
Board of Directors of the Company. To the best of the Company's knowledge, none
of such persons has any direct or indirect ownership interest in any firm or
corporation with which the Company is affiliated or with which the Company has a
business relationship, or any firm or corporation that competes with the
Company. Except as set forth on Schedule 2.9, no officer, director, or
stockholder or any member of their immediate families is,

                                       4
<PAGE>   5

directly or indirectly, interested in any contract with the Company (other than
such contracts as relate to any such person's ownership of capital stock or
other securities of the Company). Schedule 2.9 contains a list of all agreements
or transactions currently in effect between the Company and Brad Sachs, Andra
Sachs or any person or entity owned or controlled by either of them in which the
amount involved exceeds $60,000.

        2.10 REGISTRATION RIGHTS. Except as provided in the Amended and Restated
Investors' Rights Agreement, the Company is presently not under any obligation
and has not granted any rights to register under the Securities Act any of its
presently outstanding securities or any of its securities that may subsequently
be issued.

        2.11 LICENSES; PERMITS. The Company has all franchises, permits,
licenses, and any similar authority necessary for the conduct of its business as
now being conducted by it, the lack of which could materially and adversely
affect the business, properties, prospects, or financial condition of the
Company, and believes it can obtain, without undue burden or expense, any
similar authority for the conduct of its business as presently planned to be
conducted. The Company is not in default in any material respect under any of
such franchises, permits, licenses or other similar authority.

        2.12 LITIGATION. Except as set forth on Schedule 2.12, there is no
action, suit, proceeding, or investigation pending or, to the Company's
knowledge, currently threatened against the Company that questions the validity
of this Agreement, the Amended and Restated Investors' Rights Agreement, or the
Amended and Restated Right of First Refusal and Co-Sale Agreement or the right
of the Company to enter into such agreements, or to consummate the transactions
contemplated hereby or thereby, or that might result, either individually or in
the aggregate, in any adverse change in the assets, business, properties,
prospects, or financial condition of the Company, its properties or assets, or
in any material impairment of the right or ability of the Company to carry on
its business as now conducted or proposed to be conducted. The Company is not a
party to, named in or subject to, and none of its assets are bound by, any
order, writ, injunction, judgment, or decree of any court, government agency, or
instrumentality. There is no action, suit, proceeding or investigation initiated
by the Company currently pending or that the Company currently intends to
initiate.

        2.13 YEAR 2000 COMPLIANCE. All of the Company's products (including
products currently under development) record, store, process and calculate and
present calendar dates falling on and after January 1, 2000, and calculate any
information dependent on or relating to such dates in the same manner and with
the same functionality, data integrity and performance as the products record,
store, process, calculate and present calendar dates on or before December 31,
1999, or calculate any information dependent on or relating to such dates
(collectively "Year 2000 Compliant"). The Company's computer system and its
products have been tested and, based on the results of these tests, the Company
believes that its internal systems, including without limitation, its accounting
systems, as well as its products, are Year 2000 Compliant. The Company has not
conducted a review of the computer hardware and software systems of third
parties which may be affected by the Year 2000 problem.

        2.14 OFFERING. Subject in part to the truth and accuracy of each
Investor's representations set forth in this Agreement, the offer, sale and
issuance of the Series B Preferred Stock as contemplated by this Agreement are
exempt from the registration requirements of the Securities Act, and the
qualification requirements of the California Securities Law, and neither the
Company nor any authorized agent acting on its behalf will take any action
hereafter that would cause the loss of any such exemption.

                                       5

        2.15 TITLE TO PROPERTY AND ASSETS; LIENS. The Company has good and
marketable title to its properties and assets, in each case subject to no
mortgage, pledge, lien, lease, encumbrance, or charge, other than (a) liens
resulting from taxes which have not yet become delinquent, or (b) minor liens,
encumbrances, or defects of title which do not, individually or in the
aggregate, materially detract from the value of the property subject thereto or
materially impair the operations of the Company.

        2.16 FINANCIAL STATEMENTS. The Company has delivered to each Investor
its audited financial statements for the period from May 18, 1998 (inception) to
December 31, 1998, and for the period from January 1, 1999 to June 30, 1999 and
its unaudited financial statements for the eleven-month period ended November
30, 1999 (the "Financial Statements"). The Financial Statements fairly present
the financial condition and operating results of the Company as of the dates,
and for the periods, indicated therein. The Financial Statements have been
prepared in accordance with U.S. generally accepted accounting principles
consistently applied throughout the periods indicated, except that interim
financial statements are subject to normal year-end audit adjustments (which
will not be material either individually or in the aggregate) and lack
footnotes. Except as set forth on Schedule 2.16 or in the Financial Statements,
the Company has no material liabilities, contingent or otherwise, other than (i)
liabilities incurred in the ordinary course of business consistent with past
practices subsequent to November 30, 1999 and (ii) obligations under contracts
and commitments incurred in the ordinary course of business consistent with past
practices, which, in both cases, individually or in the aggregate, are not
material to the financial condition or operating results of the Company. Except
as disclosed in the Financial Statements or on Schedule 2.16, the Company is not
a guarantor or indemnitor of any indebtedness of any other person, firm, or
corporation.

        2.17 CHANGES. Except as set forth on Schedule 2.17, since November 30,
1999, there has not been:

               (a) any change in the assets, liabilities, financial condition,
or operating results of the Company from that reflected in the Financial
Statements, except changes in the ordinary course of business consistent with
past practices that have not been, in the aggregate, materially adverse;

               (b) any damage, destruction or loss, whether or not covered by
insurance, materially and adversely affecting the business, properties,
prospects, or financial condition of the Company (as such business is presently
conducted and as it is presently proposed to be conducted);

               (c) any waiver or compromise by the Company of a material right
or of a material debt owed to it;

               (d) any satisfaction or discharge of any lien, claim, or
encumbrance or payment of any obligation by the Company, except in the ordinary
course of business consistent with past practices and that is not material to
the business, properties, prospects, or financial condition of the Company (as
such business is presently conducted and as it is presently proposed to be
conducted);

               (e) any material change to a material contract or arrangement by
which the Company or any of its assets is bound or subject;

               (f) any material change in any compensation arrangement or
agreement with any key employee, officer or director;

<PAGE>   7

               (g) any sale, assignment, or transfer of any patents, trademarks,
copyrights, trade secrets, or other intangible assets material to the Company;

               (h) any resignation or termination of employment of any key
employee of the Company; and the Company, to the best of its knowledge, does not
know of the impending resignation or termination of employment of any such
employee,

               (i) any mortgage, pledge, transfer of a security interest in, or
lien, created by the Company, with respect to any of its material properties or
assets, except for liens of the type described in Section 2.15;

               (j) any loans or guarantees made by the Company to or for the
benefit of its employees, stockholders, officers, or directors, or any members
of their immediate families, other than travel advances and other advances made
in the ordinary course of its business consistent with past practices;

               (k) any declaration, setting aside, or payment of any dividend or
other distribution of the Company's assets in respect of any of the Company's
capital stock, or any direct or indirect redemption, purchase, or other
acquisition of any of such stock by the Company;

               (l) any other event or condition of any character that might
materially and adversely affect the business, properties, prospects, or
financial condition of the Company (as such business is presently conducted and
as it is presently proposed to be conducted); or

               (m) any agreement or commitment by the Company to do any of the
things described in this Section 2.17.

        2.18 INTELLECTUAL PROPERTY. Except as set forth on Schedule 2.18, the
Company has sufficient title and ownership of all patents, patent applications,
licenses, trademarks, service marks, trade names, inventions, processes,
formulae, trade secrets, franchises, copyrights and other proprietary rights
(collectively, "Intellectual Property Rights") employed in or necessary for the
operation of its business as now conducted and as proposed to be conducted with
no known infringement of or conflict with the rights of others. Such ownership
and title are exclusive and not subject to termination without the Company's
consent. Except as set forth on Schedule 2.18, there are no outstanding options,
licenses, or agreements of any kind relating to the foregoing Intellectual
Property Rights, nor is the Company bound by or a party to any options, licenses
or agreements of any kind with respect to the Intellectual Property Rights of
any other person or entity. The Company is not aware of any third party that is
infringing or violating any of its Intellectual Property Rights. Except as set
forth on Schedule 2.18, the Company has not received any communications alleging
that the Company has violated or, by conducting its business as proposed, would
violate any of the Intellectual Property Rights of any other person or entity.
The Company does not believe it is or will be necessary to use any inventions of
any of its employees (or persons it currently intends to hire) made prior to
their employment by the Company.

        2.19 EMPLOYEES; EMPLOYEE COMPENSATION. To the best of the Company's
knowledge, after reasonable inquiry, no employee of the Company is obligated
under any contract (including licenses, covenants, or commitments of any nature)
or other agreement, or subject to any judgment, decree or order of any court or
administrative agency that would conflict with such employee's obligation to use
his or her best efforts to promote the interests of the Company or that would
conflict

                                       7
<PAGE>   8

with the Company's business as conducted or as proposed to be conducted. To the
best of the Company's knowledge, after reasonable inquiry, no employee of the
Company is in violation of any term of any employment contract, proprietary
information and inventions agreement, non-competition agreement, or any other
contract or agreement relating to the relationship of any such employee with the
Company or any previous employer. Neither the execution nor delivery of this
Agreement, nor the carrying on of the Company's business by the employees of the
Company, nor the conduct of the Company's business as proposed, will, to the
best of the Company's knowledge, conflict with or result in a breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees is now obligated. The
Company has no collective bargaining agreements with any of its employees and to
the best of the Company's knowledge there is no labor union organizing activity
pending or threatened with respect to the Company. Except as set forth on
Schedule 2.19, there is no pension, health, profit sharing, bonus, stock
purchase, stock option, hospitalization, insurance, severance, or any other
employee benefit or welfare benefit plan with respect to any officer or employee
of the Company which is subject to the Employee Retirement Income Security Act
of 1974, as amended ("ERISA"). The Company is not aware that any officer or key
employee, or that any group of key employees, intends to terminate their
employment with the Company, nor does the Company have a present intention to
terminate the employment of any of the foregoing. Subject to general principles
related to wrongful termination of employees, the employment of each officer and
employee of the Company is terminable at the will of the Company. Schedule 2.19
contains a true, complete and correct list of all employment agreements,
severance agreements, compensation plan agreements or arrangements or other
agreements or contractual obligations relating to the employment or service of
any of the Company's employees. True, complete and correct copies of all such
agreements have been delivered or made available to special counsel for the
Investors.

        2.20 PROPRIETARY INFORMATION.

               (a) The Company has taken all reasonable security measures to
protect the secrecy, confidentiality, and value of all trade secrets, know-how,
inventions, designs, processes, and technical data required to conduct its
business.

               (b) Each officer, employee, or consultant of the Company has
signed, and each such future officer, employee or consultant will sign, a
proprietary information agreement substantially in the Company's standard form
of such agreement (a copy of which form has been provided to the Investors'
counsel), each of which agreements remains in full force and effect as of the
date hereof. To the best of the Company's knowledge, none of the Company's
current or former officers, employees, or consultants is or will be in violation
thereof, and the Company will use its best efforts to prevent any such
violation.

        2.21 TAX RETURNS, PAYMENTS, AND ELECTIONS. The Company has filed all tax
returns (federal, state or local) it has been required to file prior to the date
hereof and the Company has paid all taxes that have been due and payable, and
the Company has no material liability for any federal, state or local taxes. The
Company has not elected to be treated as an S Corporation or a collapsible
corporation pursuant to Section 341(f) or Section 1362(a) of the Internal
Revenue Code of 1986, as amended ("Code"), nor has it made any other elections
pursuant to the Code (other than elections that relate solely to methods of
accounting, depreciation or amortization) that would have a material effect on
the Company, its financial condition, its business as presently conducted or
proposed to be conducted or any of its properties or material assets. The
Company has never had any tax deficiency proposed or assessed against it and has
not executed any waiver of any statute of limitations on the

                                       8
<PAGE>   9

assessment or collection of any tax or governmental charge. The Company has
withheld or collected from each payment made to each of its employees, the
amount of all taxes, including, but not limited to, federal income taxes,

assistant for each party) and shall attempt in good faith to resolve the
dispute. If the disputes cannot be resolved by such senior managers in such
meeting, the parties agree that they shall, if requested in writing by either
party, meet within thirty (30) days after such written notification for one day
with an impartial mediator and consider dispute resolution alternatives other
than litigation. If any alternative method of dispute resolution is not agreed
upon within thirty (30) days after the one day mediation, either party may begin
litigation proceedings. This procedure shall be a prerequisite before taking any
additional action hereunder.

        7.13 INFORMATION CONFIDENTIAL.

               (a) Disclosure of Terms. The terms and conditions of this
Agreement, the Amended and Restated Investors' Rights Agreement, the Amended and
Restated Right of First Refusal and Co-sale Agreement and any other agreement to
which the Investors are parties, the execution and delivery of which is
contemplated hereby (collectively, the "Financing Terms"), including their
existence, shall be considered confidential information and shall not be
disclosed by any party hereto to any third party except in accordance with the
provisions set forth below.

               (b) Press Releases, Etc. Within sixty (60) days of the closing of
the transaction contemplated by the Financing Terms, the Company may issue a
press release in the form provided by Intel disclosing that Intel has invested
in the Company; provided that the release does not disclose any of the Financing
Terms and the final form of the press release is approved in advance in writing
by Intel which approval shall not be unreasonably withheld. No other
announcement regarding Intel in a press release, conference, advertisement,
announcement, professional or trade publication, mass marketing materials or
otherwise to the general public may be made without such Intel's prior written
consent.

               (c) Permitted Disclosures. Notwithstanding the foregoing, (i) any
party may disclose any of the Financing Terms to its current or bona fide
prospective investors, employees, investment bankers, lenders, accountants and
attorneys, in each case only where such persons or entities are under
appropriate nondisclosure obligations whether by written agreement, position of
trust or confidence, fiduciary duty, or otherwise; (ii) any party may disclose
(other than in a press release or other public announcement described in
subsection (b)) solely the fact that the Investors are investors in the Company
to any third parties without the requirement for the consent of any other party
or nondisclosure obligations; and (iii) Intel may disclose its investment in the
Company and the Financing Terms to third parties or to the public at its sole
discretion and, if it does so, the other parties hereto shall have the right to
disclose to third parties any such information disclosed in a press release or
other public announcement by Intel.

        (d) Legally Compelled Disclosure. In the event that any party is
requested or becomes legally compelled (including without limitation, pursuant
to securities laws and regulations) to disclose the existence of this Agreement,
the Amended and Restated Investors' Rights Agreement, the Amended and Restated
Right of First Refusal and Co-Sale Agreement and any other agreement to which
the Investors are parties, the execution and delivery of which is contemplated
hereby, or any of the Financing Terms hereof in contravention of the provisions
of this Section 7.13, such party (the "Disclosing Party") shall provide the
other parties (the "Non-Disclosing Parties") with prompt written notice of that
fact so that the appropriate party may seek (with the cooperation and reasonable
efforts of the other parties) a protective order, confidential treatment or
other appropriate remedy. In such event, the Disclosing Party shall furnish only
that portion of the information which is legally


                                       18
<PAGE>   19

required and shall exercise reasonable efforts to obtain reliable assurance that
confidential treatment will be accorded such information to the extent
reasonably requested by any Non-Disclosing Party.

               (e) Other Information. The provisions of this Section 7.13 shall
be in addition to, and not in substitution for, the provisions of any separate
nondisclosure agreement executed by any of the parties hereto with respect to
the transactions contemplated hereby. Additional disclosures and exchange of
confidential information between the Company and Intel (including without
limitation, any exchanges of information with any Intel board observer) shall be
governed by the terms of the Corporate Non-Disclosure Agreement No. 5710225,
dated May 4, 1999, executed by the Company and Intel, and any Confidential
Information Transmittal Records ("CITR") provided in connection therewith.

               (f) All notices under this Section 7.13 shall be made pursuant to
Section 7.6 of this Agreement.
