                                   AGREEMENT
                                   ---------

     1.   Registration Rights.
          -------------------

          1.1  Definitions.  As used in this Agreement, the following terms
               -----------
shall have the following respective meanings:

               (a)  The terms "register," "registered" and "registration" refer
to (i) a registration of an offering of securities effected by preparing and
filing a registration statement in compliance with the Securities Act, and the
declaration or ordering of the effectiveness of such registration statement and
(ii) the qualification or compliance of such offering of securities under
applicable state blue-sky laws, and the filing of all necessary amendments or
undertakings therefor.

               (b)  The term "Registrable Securities" means (i) any and all
shares of Common Stock of the Company issued upon conversion of the Preferred
Shares or upon exercise of that certain warrant to purchase 131,839 shares of
Preferred Stock issued to Intel Corporation on June 25, 1998 or upon exercise of
that certain warrant to purchase up to 100,000 shares of Common Stock to be
issued by the Company to a corporate partner, no later than April 30, 2000; (ii)
any and all shares of stock issued or issuable in lieu of any of the stock
referred to in clause (i) in any reorganization; and (iii) any and all shares of
stock issued (or issuable upon the conversion or exercise of warrants, options
or any other security which is issued) in respect of any of the stock referred
to in clauses (i) and (ii) as a result of a stock split, stock dividend,
recapitalization or the like; provided that, in every case, particular shares of
any of the foregoing shall cease to be Registrable Securities once they have
been sold in any public offering.

               (c)  The terms "Series A Registration Right Securities," "Series
B Registration Right Securities," "Series C Registration Right Securities,"
"Series D Registration Right Securities," "Series E Registration Right
Securities," and "Series F Registration Rights Securities" mean, as applicable
to the appropriate Series, or "Registration Right Securities" as applicable to
the Series A, Series B, Series C, Series D, Series E and Series F Registration
Right Securities collectively, (i) the Series A Shares, Series B Shares, Series
C Shares, Series D Shares, Series E Shares or Series F Shares separately or
collectively as applicable; and (ii) any and all Registrable Securities issued
in respect of the foregoing. Whenever any provision in this Agreement refers to
a majority, percentage, proportion, number or amount of the Registration Right
Securities, the calculation is to be made and determined as if all securities of
the applicable Series or all Series collectively, as applicable, that might be
converted into or exercised to obtain Registrable Securities had been converted
and/or exercised for the full number of Registrable Securities obtainable.

               (d)  The terms "Holder" or "Holders" means any person or persons
who hold Registration Right Securities and each person to whom Registration
Right Securities were originally issued or who is a qualified transferee under
Section 1.10 (Transfer of Registration Rights below).

                                      -2-
<PAGE>

               (e)  The term "Initiating Holders" means any Holders of not less
than 20% of the Registration Right Securities then outstanding or a lesser
percentage if the anticipated aggregate offering price of the securities to be
registered exceeds $10,000,000.

               (f)  The term "Participating Holders" means any Holder or Holders
who have, by proper notice, requested inclusion of Registrable Securities of the
applicable Series in the relevant public offering and who have, if applicable,
agreed to participate in any related underwriting.

               (g)  The term "SEC" means the Securities and Exchange Commission.

               (h)  The term "Securities Act" means the Securities Act of 1933,

1934, as amended or any similar successor Federal statute and the rules and
regulations thereunder, all as of the same shall be in effect from time to time.

               (j)  The term "public offering" means a registered offering of
the Company's securities to the general public (other than an offering covered
by a registration statement relating solely to a sale of securities to employees
of the Company pursuant to a stock option, stock purchase or similar plan or a
transaction within the scope of Rule 145 promulgated under the Securities Act).
The first firm commitment public offering of the Company's securities,
underwritten by a nationally-known underwriter, with net proceeds to the Company
of $20,000,000 or more and at a price per share of $9.00 or higher is termed the
"Initial Public Offering."

          1.2  Demand Registration

               (a)  Request for Registration.  If the Company receives from
                    ------------------------
Initiating Holders at any time or times not earlier than (i) three years after
July 6, 2000 or (ii) six months after the effective date of the first
registration statement filed by the Company covering an underwritten public
offering of any of its securities to the general public, a written request that
the Company register Registrable Securities equivalent to at least twenty
percent (20%) of the aggregate number of Registration Right Securities then
outstanding, or a lesser percentage if the anticipated aggregate offering price
of the Registrable Securities to be registered, net of standard underwriting
discounts, is no less than $10,000,000, the Company will:

                    (i)  promptly give written notice of the proposed
registration to all other Holders; and

                    (ii) as soon as practicable, use its best efforts to
register such securities as requested and to facilitate the sale and
distribution of the Initiating Holders' Registrable Securities as specified in
such request, together with the Registrable Securities of any Holders joining in
such request as are specified in a written request given within 20 days after
receipt of such written notice from the Company.

                                      -3-
<PAGE>

     Notwithstanding the foregoing, the Company shall not be obligated to take
any action to effect such registration pursuant to this Section 1.2 (Demand
Registration) in the following instances:

                         (A)  If the registration would become effective within
180 days following the effective date of a public offering by the Company of its
securities for its own account;

                         (B)  in any particular jurisdiction in which the
Company would be required to execute a general consent to service of process
unless the Company is already subject to service in such jurisdiction and except
as required by the Securities Act; or

                         (C)  after the Company has effected two (2)
registrations pursuant to subsection 1.2(a) and such registrations have been
declared or ordered effective.

     Subject to the foregoing clauses (A) through (C), the Company shall file a
registration statement covering the Registrable Securities requested to be
registered as soon as practical, but in any event within 90 days after receipt
of the request of the Initiating Holders.  If the Company furnishes to the
Holders a certificate signed by the Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the Company
it would be seriously detrimental to the Company and its shareholders for a
registration statement to be filed at the time requested, the Company shall have
an additional period of not more than 90 days after the expiration of the
initial 90 day period within which to file the registration statement;
provided, however, that the Company may not utilize this right more than once in
any twelve-month period.

               (b)  Underwriting.  If the Initiating Holders intend to
                    ------------
distribute the Registrable Securities covered by their request by means of an
underwriting, they shall so advise the Company as part of their request made
pursuant to Section 1.2(a) (Request for Registration). The Company shall include
such information in the written notice referred to in Section 1.2(a)(i). In such
event, the underwriters shall be selected by the Company and must be reasonably
acceptable to a majority in interest of the Initiating Holders. The right of any
Holders to registration pursuant to this Section 1.2 (Demand Registration) shall
be conditioned upon such Holders' participation in such underwriting and the
inclusion of such Holders' Registrable Securities in the underwriting (unless
otherwise mutually agreed by a majority in interest of the Participating Holders
and such Holders) to the extent provided herein. The Company and all Holders
registering securities shall enter into an underwriting agreement in customary
form with the underwriters. Notwithstanding any other provision of this Section
1.2 (Demand Registration), if the underwriters advise the Company in writing
that marketing factors require a limitation of the number of shares to be
underwritten, the Company shall so advise all Holders of Registration Right
Securities. The number of shares of Registrable Securities that may be included
in the registration and underwriting shall be reduced in proportionate amounts
of each Series as the underwriters require and shall be allocated among the
Participating Holders in proportion, as nearly as practicable, as the respective
amounts of Registration Right Securities then held by each Participating Holder
bears to the total number of Registration Right Securities held by all
Participating Holders. If any of the Participating Holders disapproves of the
terms of the underwriting, such Holders may elect to withdraw therefrom by
written notice to the Company, the underwriter and the other Participating
Holders. Any Registrable

                                      -4-
<PAGE>

Securities which are excluded from the underwriting by reason of the
underwriters' marketing limitation or withdrawn from such underwriting at the
request of the Holders thereof shall be withdrawn from such registration.

          1.3  Company Registration.
               --------------------

               (a)  Registration.  If the Company shall determine to register
                    ------------
any of its securities for its own account, the Company will:

                    (i)  promptly give to each of the Holders written notice
thereof (which shall include a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable blue sky or
other state securities laws); and

                    (ii) include in such registration, and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 20 days after receipt of such written notice from the
Company, by any Holders, except as limited under Section 1.3(b) (Underwriting)
below.

     Notwithstanding the foregoing, the Company shall not be required to notify
Holders or include Registrable Securities in any registration (i) relating
solely to employee stock option or purchase plans on Form S-1, S-3 or S-8, (ii)
relating solely to a transaction within the scope of Rule 145 on Form S-4, or
(iii) on any other form (other than Form S-1, S-2, S-3, SB-1 or SB-2, or their
successor forms) or any successor to such forms, which does not include
substantially the same information as would be required to be included in a
registration statement covering a registration pursuant to Section 1.2 (Demand
Registration) above.

               (b)  Underwriting.  If the registration of which the Company
                    ------------
gives notice is for a public offering involving an underwriting, the Company
shall so advise the Holders as a part of the written notice given pursuant to
Section 1.3(a)(i). In such event the right of any Holders to registration
pursuant to Section 1.3 (Company Registration) shall be conditioned upon such
Holders' participation in such underwriting and the inclusion of such Holders'
Registrable Securities in the underwriting to the extent provided herein. The
Company and all Holders proposing to distribute their securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriters selected by the Company. Notwithstanding any other provision of
this Section 1.3 (Company Registration), if the underwriters determine that
marketing factors require a limitation of the number of shares to be
underwritten, the underwriters and the Company may limit the number of
Registrable Securities to be included in the registration and underwriting, or
may exclude Registrable Securities entirely from such registration and
underwriting; provided, however, that no Registrable Securities shall be so
excluded unless there are first excluded all other securities proposed to be
included in such registration (other than securities registered for the account
of the Company); and further provided that, except in the Company's first
underwritten public offering, the Registrable Securities to be included in such
registration may not be limited to less than 25% of the total number of
securities to be included in such registration. In the event of any such
limitation of the number of shares to be underwritten, the Company shall so
advise all Participating Holders, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among the Participating Holders in proportion, as nearly as

                                      -5-
<PAGE>

practicable, as the respective amounts of Registration Right Securities then
held by each Participating Holder bears to the total number of Registration
Right Securities held by all Participating Holders. If any Participating Holder
disapproves of the terms of any such underwriting, it may elect to withdraw
therefrom by written notice to the Company and the underwriter. Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration. If shares are withdrawn from registration, the Company may
offer to all other Holders offering Registrable Securities in the registration
the right to include additional securities in the registration, with such shares
being allocated on a pro rata basis among the Holders.

          1.4  Form S-3.  Following the Company's Initial Public Offering, the
               --------
Company shall use its best efforts to become eligible to register offerings of
securities on SEC Form S-3 or its successor form. After the Company has
qualified for the use of Form S-3, Holders of Registrable Securities then
outstanding shall have the right to request registration on Form S-3 (which
request shall be in writing and shall state the number of shares of Registrable
Securities to be registered and the intended method of disposition of shares by
such Holders); provided that no more than one such registration must be effected
during any twelve-month period and no more than a total of four such
registrations must be effected.

     Notwithstanding the foregoing:

               (a)  The Company shall not be required to effect a registration
pursuant to this Section 1.4 (Form S-3) within 180 days of the effective date of
any registration pursuant to this Section 1.4 (Form S-3), Section 1.2 (Demand
Registration) or Section 1.3 (Company Registration) above within the same
calendar year as the last registration pursuant to this Section 1.4 (Form S-3).

               (b)  The Company shall not be required to effect a registration
pursuant to this Section 1.4 (Form S-3) unless the Holders requesting
registration propose to dispose of Registrable Securities having an anticipated
aggregate price to the public (before deduction of underwriting discounts and
expenses of sale) of at least $500,000; and

               (c)  The Company shall have the right to defer filing a
registration statement pursuant to this Section 1.4 (Form S-3) for a period of
up to 120 days following the requested filing date if the Company furnishes to
the Holders requesting registration a certificate signed by the Chief Executive
Officer of the Company stating that in the good faith judgment of the Company's
Board of Directors it would be seriously detrimental to the Company and its
shareholders for a registration statement to be filed at the time requested;
provided, however, that the Company may not utilize this right more than once in
any twelve-month period.

     The Company shall give written notice to all Holders of record of the
receipt of a request for registration pursuant to this Section 1.4 (Form S-3)
and shall provide a reasonable opportunity for other Holders to participate in
the registration, provided that if the registration is for an underwritten
offering, the terms of Section 1.2(b) (Underwriting) shall apply to all
participants in such offering. Subject to the foregoing, the Company will use
its best efforts to effect promptly the registration of all shares of
Registrable Securities on Form S-3 to the extent requested by the Holders
thereof for purposes of disposition.

                                      -6-

          1.5  Expenses of Registration.  All expenses incurred in connection
               ------------------------
with any registration pursuant to this Section 1 (Registration Rights),
including, without limitation, all registration, filing and qualification fees,
printing expenses, fees and disbursements of counsel for the Company, the
reasonable fees and expenses of one special counsel for all Participating
Holders and expenses of any special audits incidental to or required by such
registration, shall be borne by the Company except as follows:

               (a)  The Company shall not be required to pay for expenses of any
registration proceeding begun pursuant to Section 1.2 (Demand Registration), the
request for which has been subsequently withdrawn by a majority in interest of
the Participating Holders of the applicable Series requesting such registration,
unless the requested registration is withdrawn due to a change in market
conditions or a material change in the Company or its business of which the
Participating Holders of the applicable Series requesting such registration were
previously unaware.

               (b)  The Company shall not be required to pay underwriters' fees,
discounts, commissions or transfer taxes relating to Registrable Securities.

     All expenses of any registered offering not otherwise borne by the Company
shall be borne pro rata among the Participating Holders of the applicable Series
(and the Company and other holders selling securities in the offering) on the
basis of the number of shares registered.

          1.6  Registration Procedures. In the case of each registration
               -----------------------
effected by the Company pursuant to this Agreement, the Company will keep each
Participating Holder advised in writing as to the initiation of registration,
qualification and compliance and as to the completion thereof. Except as
otherwise provided in Section 1.5 (Expenses of Registration), at its expense the
Company will:

               (a)  Prepare and file with the SEC a registration statement with
respect to the offering of such Registrable Securities and use its best efforts
to cause such registration statement to become effective, and, upon the request
of a majority in interest of the Participating Holders keep such registration
statement effective for up to 120 days.

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

               (c)  Furnish to the Participating Holders such numbers of copies
of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of their securities
covered by such registration statement.

               (d)  Use commercially reasonable 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 Participating Holders, provided that the Company shall not be
required in connection therewith or as a condition thereto to qualify to do

                                      -7-
<PAGE>

business or to file a general consent to service of process in any such states
or jurisdictions, unless the Company is already subject to service in such
jurisdiction and except as may be required by the Securities Act.

               (e)  In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each
Participating Holder shall also enter into and perform its obligations under
such an agreement.

               (f)  Notify each Participating Holder at any time when a
prospectus relating thereto is required to be delivered under the Securities Act
or upon 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)  Cause all Registrable Securities covered by such
registration statement to be listed on each securities exchange or authorized
for quotation on each automated quotation system on which similar securities
issued by the Company are then listed or authorized for quotation.

               (h)  Provide a transfer agent and registrar and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of such registration.

               (i)  Furnish, at the request of any Participating Holder, on the
date that the securities are delivered to the underwriters for sale in
connection with a registration being sold through underwriters, (i) an opinion,
dated such date, of the counsel representing the Company for the purposes of
such registration, in form and substance as is customarily given to underwriters
in an underwritten public offering, addressed to the underwriters, if any, and
to the Participating Holders and (ii) a letter dated such date, from the
independent certified public accountants of the Company, in form and substance
as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

               (j)  In the event of any underwritten public offering, cooperate
with the Participating Holders, the underwriters participating in the offering
and their counsel in any due diligence investigation reasonably requested by the
Participating Holders or the underwriters in connection therewith, and
participate, to the extent reasonably requested by the managing underwriter for
the offering or the Participating Holders, in efforts to sell the Registrable
Securities under the offering (including, without limitation, participating in
"roadshow" meetings with prospective investors) that would be customary for
underwritten primary offerings of a comparable amount of equity securities by
the Company.

          1.7  Indemnification.
               ---------------

               (a)  By the Company.  The Company will indemnify each Holder of
                    --------------
Registrable Securities with respect to which registration has been effected
pursuant to this

                                      -8-
<PAGE>

Agreement, each of its officers, directors and partners, each person controlling
such Holders within the meaning of the Securities Act, each underwriter of
offerings effected pursuant to this Agreement, if any, and each person who
controls any such underwriter within the meaning of the Securities Act, against
all claims, losses, expenses, damages and liabilities (or actions in respect
thereto), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
prospectus, offering circular or other document (including any related
registration statement, notification or the like) incident to any such
registration, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statement
therein not misleading, or any violation or alleged violation by the Company of
the Securities Act, the Exchange Act or any state securities law applicable to
the Company or any rule or regulation promulgated under the Securities Act, the
Exchange Act or any such state law in connection with any such registration. The
Company will reimburse each such Holder, each of its officers, directors and
partners, and each person controlling such Holder, each such underwriter and
each person who controls any such underwriter, within a reasonable amount of
time after such expense is incurred for any reasonable legal and any other
expenses incurred in connection with investigating, defending or settling any
such claim, loss, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 1.7(a) (By the Company) shall not
apply to amounts paid in settlement of any such claim, loss, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld); and provided further, that
the Company will not be liable in any such case to the extent that any such
claim, loss, damage or liability arises out of or is based on any untrue
statement or omission based upon written information furnished to the Company
expressly for use in connection with such registration by any such Holder,
officer, director, partner, underwriter or controlling person.

               (b)  By the Holders.  Each Holder will, as to each registration
                    --------------
in which such Holder is a Participating Holder, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company within the meaning of the Securities Act, and each other such
Holder, each of its officers, directors and partners and each person controlling
such Holder, against all claims, losses, expenses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the Company, and such Holders, directors, officers, partners, persons and
underwriters for any reasonable legal or any other expenses incurred in
connection with investigating, defending or settling any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder
specifically for use therein; provided, however, that (i) the indemnity
agreement contained in this Section 1.7(b) (By the Holders) shall not apply to
amounts paid in settlement of any such claim, loss, damage, liability or action
if such settlement is effected without the consent of the Holder (which consent
shall not be unreasonably withheld) and (ii) that the total amount for which any
Holder shall be liable under this

                                      -9-
<PAGE>

Section 1.7(b) (By the Holders) shall not in any event exceed the aggregate
proceeds received by such Holder from the sale of Registrable Securities held by
such Holder in such registration.

               (c)  Indemnification Procedures.  Each party entitled to
                    --------------------------
indemnification under this Section 1.7 (Indemnification) (the "Indemnified
Party") shall give notice to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom; provided that counsel for the Indemnifying Party proposed
to conduct the defense of such claim or litigation shall be approved by the
Indemnified Party (whose approval shall not be unreasonably withheld), and the
Indemnified Party may participate in such defense at such Indemnified Party's
election and expense; provided further, that the failure of any Indemnified
Party to give notice as provided herein shall not relieve the Indemnifying Party
of its obligations hereunder, unless (and only to the extent that) such failure
resulted in prejudice to the Indemnifying Party; and provided further, that an
Indemnified Party (together with all other Indemnified Parties which may be
represented without conflict by one counsel) shall have the right to retain one
separate counsel, with the fees and expenses of such counsel to be paid by the
Indemnifying Party, if representation of such Indemnified Party by the counsel
retained by the Indemnifying Party would be inappropriate due to actual or
potential differing interests between such Indemnified Party and any other party
represented by counsel for the Indemnifying Party in such proceeding. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to all Indemnified Parties
of a release from all liability in respect to such claim or litigation.

     If the indemnification provided for in this Section 1.7 is held by a court
of competent jurisdiction to be unavailable to an Indemnified Party with respect
to any loss, liability, claim, damage, or expense referred to herein, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder,
shall contribute to the amount paid or payable by such Indemnified Party as a
result of such loss, liability, claim, damage, or expense in such proportion as
is appropriate to reflect the relative fault of the Indemnifying Party, on the
one hand, and of the Indemnified Party, on the other, in connection with the
statement or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable consideration. The relative
fault of the Indemnifying Party and of the Indemnified Party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission to state a material fact relates to
information supplied by the Indemnifying Party or by the Indemnified Party and
the parties' relative intent, knowledge, access to information, and opportunity
to correct or prevent such statement or omission.

          1.8  Information by Holders.  Any Participating Holders shall promptly
               ----------------------
furnish in writing to the Company such information regarding such Holders and
the distribution proposed by such Holders as the Company may reasonably request
in writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

                                      -10-
<PAGE>

          1.9  Rule 144 Reporting.  With a view to making available to Holders
               ------------------
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees at all times to:

               (a)  make and keep public information available, as those terms
are understood and defined in Rule 144 promulgated under the Securities Act
("Rule 144"), from and after 90 days after the effective date of the
registration for the first public offering of the Company;

               (b)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
(at any time after the Company has become subject to such reporting
requirements); and

               (c)  so long as a Holder owns any Registration Right Securities,
to furnish to such Holder forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of Rule 144 (at any
time from and after 90 days after the effective date of the registration
statement filed by the Company for the first public offering) and the Securities
Act and Exchange Act (at any time after it has become subject to such reporting
requirements), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents filed with the SEC by the Company
as the Holder may reasonably request in complying with any rule or regulation of
the SEC allowing the Holder to sell any such securities without registration.

          1.10 Transfer of Registration Rights.  Each Holder's rights to cause
               -------------------------------
the Company to register their Registrable Securities and to keep information
available, granted to them by the Company under this Section 1 (Registration
Rights), may be assigned to a transferee or assignee who (a) receives all of the
Registration Right Securities originally purchased by any transferring or
assigning Holders or (b) receives Registration Right Securities which, upon full
exercise and conversion, represent the right to obtain at least 50,000 shares of
Registrable Securities (as adjusted for stock dividends, stock split,
recapitalizations and the like); provided that the Company is given written
notice by such Holders at the time of or within a reasonable time after said
transfer, stating the name and address of said transferee or assignee and
identifying the securities with respect to which such rights are being assigned;
and provided further that, upon request by the Company, such permitted
transferee or assignee executes a counterpart to this Agreement. The Company may
prohibit the transfer of any Holder's rights under this Section 1.10 (Transfer
of Registration Rights) to any proposed transferee or assignee who the Company
reasonably believes is a competitor of the Company. Notwithstanding any
provision of this Section 1.10, such rights may be assigned by a Holder to a
limited partner, general partner or any "affiliate" (as that term is defined in
Rule 405 under the Securities Act) of a Holder at any time and without regard to
any minimum number of Shares transferred requirement.

          1.11 "Market Stand-Off" Agreement.  Each Holder hereby agrees that,
                ---------------------------
during the period of duration (not to exceed 180 days) specified by the Company
and an underwriter of common stock or other securities of the Company, following
the effective date of the first registration statement of the Company filed
under the Securities Act, it shall not, to the extent requested by the Company
and such underwriter, directly or indirectly sell, offer to sell, contract to
sell (including, without limitation, any short sale), grant any option to
purchase or otherwise transfer or dispose of (other than to donees who agree to
be similarly bound) any securities of the Company

                                      -11-
<PAGE>

held by it at any time during such period except common stock included in such
registration; provided, however, that such agreement shall not be required
unless all executive officers, directors and the other Holders enter into
similar agreements.

     In order to enforce the foregoing covenant, the Company may impose stop-
transfer instructions with respect to the Registrable Securities of each Holder
(and the shares of securities of every other person subject to the foregoing
restriction) until the end of such period.

          1.12  Termination of Registration Rights.  The obligations of the
                ----------------------------------
Company pursuant to this Section 1 (Registration Rights) shall terminate with
respect to all Holders seven (7) years from the effective date of the Initial
Public Offering; provided, however, that prior to such time a Holder shall not
                 --------  -------
be entitled to exercise its registration rights hereunder if (i) the Company is
then providing current public information within the meaning of Rule 144(c)(1),
(ii) such Holder is able to sell under Rule 144 during a 3-month period all of
the remaining Registrable Securities issued or issuable to such Holder, and
(iii) such Holder holds less than one percent (1%) of the Company's outstanding
stock.

          1.13  Other Registration Rights.  The Company must have the written
                -------------------------
consent of Holders of a majority of the Registration Right Securities before it
may grant (a) any rights to require the Company to register securities (other
than "piggyback" registration rights) or (b) any "piggyback" registration rights
superior to or on a parity with the rights granted pursuant to Section 1.3
(Company Registration) hereof.

     2.   Holders' Right of First Offer.
          -----------------------------

          2.1   Right.  The Company hereby grants to each Holder, on the terms
                -----
set forth in this Section 2 (Holders' Right of First Offer), the first right to
purchase such Holders' pro rata share (or any part thereof) of all Equity
Securities (as defined in Section 2.7 (Equity Securities)) which the Company may
from time to time desire to issue on the same terms as the Company is willing to
sell such Equity Securities to any other person. Each Holder's pro rata share of
the Equity Securities shall be equal to the percentage of the outstanding shares
of common equivalents of the Company held by such Holder on the date of the
Company's written notification referred to in Section 2.2 (Notice; Over-
Allotment) below. For purposes of this Section 2.1 (Right), the "common
equivalents" of the Company shall include all shares of common stock issuable
upon conversion or exercise of any securities convertible into or exercisable
for shares of Common Stock of the Company, including but not limited to any
shares of Preferred Stock.

          2.2   Notice; Over-Allotment.  Prior to any sale or issuance by the
                ----------------------
Company of any Equity Securities, the Company shall notify each Holder in
writing of its intention to sell and issue such securities, setting forth the
terms under which it proposes to make such sale. Within 20 days after receipt of
such notice, each Holder shall notify the Company whether it elects to exercise
its right to purchase such Holder's full pro rata share (or any part thereof) of
the Equity Securities so offered. If the Holder elects to purchase such Holder's
full pro rata share ("Electing Holder"), then such Electing Holder shall have a
right of over-allotment such that if any other Holder fails to purchase such
other Holder's full pro rata share of the Equity Securities, the Electing Holder
may purchase, on a pro rata basis with other Electing Holders, that portion of
the Equity Securities (the

                                      -12-
<PAGE>

"Remaining Securities") which such other Holder elected not to purchase. Each
such Electing Holder shall specify in its notification to the Company whether it
also elects to purchase its pro rata portion of the Remaining Securities, if
any.

          2.3  Failure to Notify.  After expiration of all notice periods
               -----------------
specified in Section 2.2 (Notice; Over-Allotment) above, the Company may, during
a period of 90 days following the end of such notice periods, sell and issue
such Equity Securities as to which the Holders do not indicate a desire to
purchase to other persons, upon terms and conditions not less favorable to the
Company than those set forth in the notice to the Holders. In the event the
Company has not sold the Equity Securities within said 90 day period, the
Company shall not thereafter issue or sell any Equity Securities without first
offering such securities to the Holders in the manner provided above.

          2.4  Payment.  If a Holder gives the Company notice that such Holder
               -------
desires to purchase any of the Equity Securities offered by the Company, payment
for the Equity Securities shall be by check or wire transfer against delivery of
the Equity Securities at the executive offices of the Company within 10 days
after giving the Company such notice, or, if later, the closing date for the
sale of such Equity Securities proposed by the Company. The Company and any
affected Holder shall take all such action as may be required by any regulatory
authority in connection with the exercise by a Holder of the right to purchase
Equity Securities as set forth in this Section 2 (Holders' Right of First
Offer).

          2.5  Limitations on Right.  The right of first offer contained in this
               --------------------
Section 2 (Holders' Right of First Offer) shall not apply to (a) Equity
Securities issuable upon conversion of the Preferred Shares; (b) the issuance by
the Company of Equity Securities to directors, employees, consultants, equipment
lessors, licensors of technology to the Company, financial institutions or other
vendors of the Company pursuant to arrangements, contracts or plans approved by
the Company's Board of Directors, including the affirmative vote of a majority
of the directors elected by the holders of the Series B Preferred Stock; (c) the
issuance of Equity Securities pursuant to the acquisition of all or part of
another corporation by merger, other reorganization or otherwise, or by the
purchase of all or substantially all of the assets of, such other company
(including Equity Securities issued or issuable to persons formerly employed by
such other company and subsequently hired by the Company); (d) Equity Securities
issued pursuant to a stock split, stock dividend or recapitalization or the
like; or (e) Equity Securities offered pursuant to an Initial Public Offering.

          2.6  Termination.  The right of first offer contained in this Section
               -----------
2 (Holders' Right of First Offer) shall terminate (a) upon the closing of any
merger or consolidation of the Company with any other corporation in which more
than 50% of the voting control of the resulting entity is held by or transferred
to third parties or (b) immediately prior to the closing of the Initial Public
Offering of the Company.

          2.7  Equity Securities.  The term "Equity Securities" shall mean (a)
               -----------------
the Company's equity securities; (b) rights, options or warrants to subscribe
for, purchase or otherwise acquire any equity security of the Company; (c) any
security convertible into or exchangeable for any of the foregoing; and (d) any
agreement or commitment to issue any of the foregoing.

<PAGE>

          2.8  Waiver of Rights.  The Series A Holders, Series B Holders, the
               ----------------
Series C Holders, the Series D Holders and the Series E Holders, by the
execution of holders of a majority in interest of each of the Series A Preferred
Stock, the Series B Preferred Stock, the Series C Preferred Stock, the Series D
Preferred Stock and the Series E Preferred Stock, hereby (i) acknowledge and
agree that this Agreement replaces and supersedes the Fourth Amended and
Restated Investor Rights Agreement dated as of March 28, 2000 (the "Series E
Rights Agreement"), and (ii) waive the provisions of Section 2 contained in the
Series E Rights Agreement as such provisions apply to the issuance and sale of
the Series F Shares offered pursuant to that certain Series F Preferred Stock
Purchase Agreement dated of even date herewith (the "Series F Agreement").

     3.   Information Rights
          ------------------

          3.1  Right to Inspect Records.  So long as a Holder holds (i) at least
               ------------------------
50,000 shares of the Series F Shares originally issued, (ii) at least 50,000
shares of the Series E Shares originally issued, (iii) at least 50,000 shares of

financial records of the Company subject to reasonable limitations, in the
judgment of the Company, on the frequency and manner of such inspections, and
the Company will deliver to such Series F Holder, Series E Holder, Series D
Holder, Series C Holder, Series B Holder or Series A Holder monthly unaudited
financial statements (including balance sheet, income statement, statement of
shareholder equity and cash flow statement) within 20 days after the end of such
period with comparison to the comparable month in the previous year and
comparison to the budget for such period on a trended basis, annual audited
financial statements (including balance sheet, income statement, statement of
shareholder equity and cash flow statement) within 120 days after the Company's
fiscal year end, and monthly and annual management projections and budgets one
month prior to the start of the Company's fiscal year. The Company's financial
statements shall be prepared in accordance with generally accepted accounting
principles subject in the case of the monthly unaudited financial statements to
normal year-end audit adjustments and the omission of footnotes.

          3.2  Termination of Financial Information; Confidentiality of
               --------------------------------------------------------
Information.  The covenants of the Company set forth in Section 3.1 (Delivery
-----------
of Financial Information) shall terminate upon the Initial Public Offering;
provided, however, that such covenants of Section 3.1 shall terminate and be of
--------  -------
no further effect as to any particular Series A Holder, Series B Holder, Series
C Holder, Series D Holder, Series E Holder or Series F Holder (other than Intel
Corporation ("Intel")) at such time as such Series A Holder, Series B Holder,
Series C Holder, Series D Holder, Series E Holder or Series F Holder is or
becomes, or is or becomes controlled by, a competitor of the Company. Each
Holder other than Intel agrees that all information obtained by such Holder
pursuant to Section 3.1 (Delivery of Financial Information) shall be deemed
proprietary and confidential to the Company and will not be disclosed to any
person or entity without the prior written consent of the Company; provided,
                                                                   --------
however, that such consent shall not be unreasonably withheld and provided
-------
further that, notwithstanding the foregoing, a Holder may disclose such
information without the prior written consent of the Company to its partners,
associates or employees in order to evaluate this investment and as may be
necessary to continue to evaluate the Company. Exchanges of confidential and
proprietary information between the Company and Intel

                                      -14-
<PAGE>

shall be governed by the terms of the Corporate Non-Disclosure Agreement No.
109883, dated March 6, 1998, executed by the Company and Intel, and any
Confidential Information Transmittal Records provided in connection therewith.
No change shall be made to this Section 3.2 without the written consent of
Intel.

          3.3  Assignment of Rights of Information.  The rights granted pursuant
               -----------------------------------
to Section 3.1 (Delivery of Financial Information), may be assigned by each
Holder to any transferee who receives registration rights pursuant to Section
1.10 (Transfer of Registration Rights) above; provided, however, that such
                                              --------  -------
rights may not be assigned to a transferee which the Company reasonably believes
is a competitor or intends to become a competitor of the Company and that any
transferee of the Holder shall agree to become subject to the obligations of the
transferring Holder under Section 3.2 (Termination of Financial Information; and
Confidentiality of Information) above.

     4.   Voting Matters

          4.1  Agreement of the Founder with Respect to Certain Voting.
               -------------------------------------------------------
Notwithstanding any provision of Section 903(a) of the General Corporation Law
of California ("Section 903") to the contrary, so long as any shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock or Series F Preferred Stock shall be
outstanding, in the event that

               (i)    a vote or written consent is taken with respect to the
authorization or issuance of any shares of any series of Preferred Stock of the
Company ("Preferred Issuance"),

               (ii)   Section 903 provides that a majority of the outstanding
shares of a class or series of a class of capital stock, voting separately as a
class or series, as applicable, must approve such Preferred Issuance, and

               (iii)  the Preferred Issuance shall have received the approval of
(x) the requisite vote of the holders of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
Preferred Stock and Series F Preferred Stock specified in the appropriate
sections of the Sixth Amended and Restated Articles of Incorporation of the
Company filed with the California Secretary of State on June 21, 2000 and (y) a
majority of the total number of outstanding shares of Common Stock, Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock and Series F Preferred Stock all
voting together as a single class on an as converted basis,

then, notwithstanding anything provided under Section 903 to the contrary, with
respect to each such Preferred Issuance, Christopher C. Marino (the "Founder")

     (a) agrees to directly vote all capital stock of the Company owned of
record or beneficially by him (the "Founder's Stock") in favor of such Preferred
Issuance, and

     (b) hereby grants a proxy to one or more of the holders of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock or Series F Preferred Stock that shall
have affirmatively voted its approval of such Preferred Issuance as his
attorney-in-fact (with full power of substitution), for and in the name of the

                                      -15-
<PAGE>

undersigned, to vote all of the Founder's Stock entitled to vote thereon, and to
execute, on behalf of the Founder, any written consent of holders of capital
stock, in favor of the approval of such Preferred Issuance.

The proxy described in clause (b) above is coupled with an interest and shall be
irrevocable until the termination of this Agreement as provided herein.

          4.2  Series B Directors.  Each Holder agrees that, at any meeting or
               ------------------
by action by written consent pursuant to which directors are to be elected or
appointed by the holders of the Series B Shares voting as a class (but not
voting together with any other series or class) pursuant to Article III, Section
3(c) of the Company's Sixth Amended and Restated Articles of Incorporation,
filed with the California Secretary of State on July __, 2000, such Holder shall
vote all of the Series B Shares owned of record or beneficially by such Holder
for one nominee proposed by Chase Venture Capital Associates ("CVCA") and one
nominee proposed by Kleiner Perkins Caufield & Byers VIII, KPCB Java Fund and
KPCB Information Sciences Zaibatsu Fund II (collectively "KPCB").

          4.3  Board Observers.  For so long as the Series B Holders have a
               ---------------
right to elect directors pursuant to the Restated Articles, the Company agrees
to permit three board observers selected by the holders of the Series B Shares
(the "Series B Observers"), two of whom shall be selected by CVCA and one of
whom shall be selected by KPCB, to attend all meetings of the Board of
Directors. For so long as Lehman Brothers Venture Capital Partners I, L.P.,
together with its affiliates (collectively "Lehman Brothers"), holds at least
250,000 shares (as adjusted for stock splits, stock dividends and similar
events) of Series C Preferred Stock, Lehman Brothers shall have the right to
select one board observer (the "Lehman Observer"). For so long as Intel
Corporation, together with its affiliates, holds at least 165,000 shares (as
adjusted for stock splits, stock dividends and similar events) of Series C
Preferred Stock, Intel Corporation shall have the right to select one board
observer (the "Intel Observer"). For so long as Sun Microsystems, together with
its affiliates, holds at least 165,000 shares (as adjusted for stock splits,
stock dividends and similar events) of Series E Preferred Stock, Sun
Microsystems shall have the right to select one board observer (the "Sun
Observer"). Each of the Series B Observers, the Lehman Observer, the Intel
Observer and the Sun Observer are sometimes referred to as an "Observer" and
collectively, as the Observers. The Company will permit the Observers to attend
all meetings of the Company's Board of Directors (the "Board") and all
committees thereof (whether in person, telephonic or other) in a non-voting,
observer capacity and shall provide to the Observer, concurrently with the
members of the Board, and in the same manner, notice of such meeting and a copy
of all materials provided to such members.

The Company acknowledges that the Intel Observer will likely have, from time to
time, information that may be of interest to the Company ("Information")
                                                           -----------
regarding a wide variety of matters including, by way of example only, (a)
Intel's technologies, plans and services, and plans and strategies relating
thereto, (b) current and future investments Intel has made, may make, may
consider or may become aware of with respect to other companies and other
technologies, products and services, including, without limitation,
technologies, products and services that may be competitive with the Company's,
and (c) developments with respect to the technologies, products and services,
and plans and strategies relating thereto, of other companies, including,
without

                                      -16-
<PAGE>

limitation, companies that may be competitive with the Company. The Company
recognizes that a portion of such Information may be of interest to the Company.
Such Information may or may not be known by the Intel Observer. The Company, as
a material part of the consideration for this Agreement, agrees that Intel and
the Intel Observer shall have no duty to disclose any Information to the Company
or permit the Company to participate in any projects or investments based on any
Information, or to otherwise take advantage of any opportunity that may be of
interest to the Company if it were aware of such Information, and hereby waives,
to the extent permitted by law, any claim based on the corporate opportunity
doctrine or otherwise that could limit Intel's ability to pursue opportunities
based on such Information or that would require Intel or the Intel Observer to
disclose any such Information to the Company or offer any opportunity relating
thereto to the Company.

     5.   General

          5.1  Regulatory Matters.
               ------------------

                    (a)  Cooperation of Other Shareholders.  Each Holder agrees
                         ---------------------------------
to cooperate with the Company in all reasonable respects in complying with the
terms and provisions of the letter agreement between the Company and CVCA dated
June 22, 1999, regarding small business matters (the "Small Business
Sideletter"), including, without limitation, voting to approve amending the
Company's Sixth Amended and Restated Articles of Incorporation, the Company's
Bylaws or this Agreement in a manner reasonably requested by CVCA or any

such request pursuant to the Small Business Sideletter.

                    (b)  Covenant Not to Amend.  The Company and each Holder
                         ---------------------
agree not to amend or waive the voting or other provisions of the Company's

a press release, conference, advertisement, announcement, professional or trade
publication, mass marketing materials or otherwise to the general public may be
made without 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; (ii) any party may disclose (other than

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 or any of the terms hereof in contravention of the provisions of this
Section 5.2, 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 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 5.2

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 Corporation
(including without limitation, any exchanges of information with any Intel
Observer) shall be governed by the terms of the Corporate Non-Disclosure
Agreement No. 109883, dated March 6, 1998, executed by the Company and Intel,
and any Confidential Information Transmittal Records provided in connection
therewith.

                    (f)  Amendment.  No change shall be made to this Section 5.2
                         ---------

particular instance, either retroactively or prospectively, and either for a
specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of its Board of Directors, may enter into
a supplementary agreement for the purpose of adding any parties or provisions to
or changing in any manner or eliminating any of the provisions of this
Agreement; provided, however, that no such modification, amendment or waiver
           --------  -------
shall reduce

<PAGE>

the aforesaid percentage of Registration Right Securities required to amend this
Agreement without the consent of all of the Holders; and, provided further, that
no such modification, amendment or waiver that would have an adverse effect on
the rights of any series of preferred stock shall be approved absent the consent
of the holders of 66 2/3% of the outstanding shares of such series. Upon the
effectuation of each such waiver, consent, agreement of amendment or
modification, the Company shall promptly give written notice thereof to the
record Holders who have not previously consented thereto in writing. This
Agreement or any provision hereof may be changed, waived, discharged or
terminated only by a statement in writing signed by the party against which
enforcement of the change, waiver, discharge or termination is sought, except to
the extent provided in this Section 5.1 (Waivers and Amendments).

          5.4  Governing Law.  This Agreement shall be governed in all respects
               -------------
by the laws of the State of California as such laws are applied to agreements
