     2.   REGISTRATION RIGHTS.

          2.1  Required Registrations. Beginning as of the date hereof and
provided that any requested registration which is for an initial public
offering shall be a Qualified Initial Public Offering:

               (a)  Each Stockholder or Stockholders holding in the aggregate
at least 10% of the Registrable Shares then issued and outstanding and held by
the Stockholders, may request, in writing, that the Company effect a
registration on Form S-1, Form S-2 or Form S-3 (or any successor form) of
Registrable Shares owned by such requesting Stockholder or Stockholders having
an aggregate value of at least $5,000,000 (based on the then current market
price or fair value), and, in addition to the foregoing, Nortel Networks may
request, in writing, that the Company effect a registration on Form S-1, Form
S-2 or Form S-3 (or any successor form) of Registrable Shares then issued and
outstanding and held by Nortel Networks; provided, however, that the Company
shall not be required to effect any registration within six months after the
effective date of any other Registration Statement of the Company; and

               (b)  Upon receipt of any request for registration pursuant to
this Section 2:

                    (i)  the Company will promptly give written notice of such
proposed registration to all other Stockholders and Nortel Networks;

                    (ii) such Stockholders and Nortel Networks shall have the
right, by giving written notice to the Company within twenty (20) calendar days
after the Company provides its notice, to elect to have included in such
registration such of their Registrable Shares as such Stockholders and Nortel
Networks may request in such notice of election, subject in the case of an
underwritten offering to the approval of the managing underwriter as provided
in Section 2.1(d) below; and

                                       5
<PAGE>
                  (iii)     thereupon, the Company shall, as expeditiously as
possible, use its best efforts to effect the registration on an appropriate
registration form of all Registrable Shares which the Company has been requested
to so register, subject to the limitations set forth herein.

     (c)  If the Initiating Holders or Nortel Networks intend to distribute the
Registrable Shares covered by their request by means of an underwriting, they
shall so advise the Company. The right of any other person to include its
securities in such registration pursuant to this Section 2.1(c) shall be
conditioned upon such other person's participation in such underwriting, as
follows:

                  (i)       Subject to Section 2.9 herein, if the Company
desires that any officers or directors of the Company holding securities of the
Company be included in any registration for an underwritten offering requested
pursuant to Section 2.1(c) or if other holders of securities of the Company who
are entitled, by contract with the Company entered into after the date of this
Agreement, to have securities included in such a registration (the "OTHER
HOLDERS") request such inclusion, the Company may include the securities of such
officers, directors and Other Holders in such registration and underwriting on
the terms set forth herein.

                  (ii)      The Company shall (together with all Stockholders,
Nortel Networks, officers, directors and Other Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form (including without limitation customary indemnification and
contribution provisions on the part of the Company) with the managing
underwriter.

                  (iii)     Notwithstanding any other provision of this Section
2.1(c), (x) in the case of a registration initiated by the Initiating Holders,
if the managing underwriter informs the Company that the inclusion of all shares
requested to be registered would adversely affect the offering, (A) the
securities of the Company held by officers or directors of the Company (other
than Registrable Shares) and the securities held by Other Holders (other than
Registrable Shares) shall be excluded from such registration and underwriting to
the extent deemed advisable by the managing underwriter, and (B) if a further
limitation of the number of shares is required, the number of shares that may be
included in such registration and underwriting shall be allocated among all
Stockholders requesting registration in any registration initiated by Initiating
Holders and Nortel Networks to the extent that Nortel Networks desires to
participate in such registration, as nearly as practicable, to the respective
number of Registrable Shares requested to be registered by them in the aggregate
at the time the respective requests for registration were made pursuant to
Section 2.1(a); provided, however, that in no event shall the number of
Registrable Shares requested to be registered (i) by the Stockholders in any
registration initiated by Initiating Holders be reduced to less than thirty
percent (30%) of any underwriting subsequent to the Qualified Initial Public
Offering of the Company and (y) in the case of a registration initiated by
Nortel Networks, if the managing underwriter informs the Company that the
inclusion of all shares requested to be registered would adversely affect the
offering, (A) the securities of the Company held by officers or directors of the
Company (other than Registrable Shares) and the securities held by Other Holders
(other than Registrable Shares) shall be excluded from such registration and
underwriting to the extent deemed advisable by the managing

                                       6
<PAGE>

underwriter, and (B) if a further limitation of the number of shares is
required, the number of shares of the Stockholders that may be included in such
registration and underwriting shall be proportionately excluded from such
registration and underwriting to the extent deemed advisable by the managing
underwriter. To facilitate the allocation of shares in accordance with the above
provisions, the Company or the underwriter(s) may round the number of shares
allocated to any person to the nearest 100 shares.

               (iv) If any holder of Registrable Shares, officer, director or
Other Holder who has requested inclusion in such registration as provided above
disapproves of the terms of the underwriting, such person may elect to withdraw
therefrom by written notice to the Company, and the securities so withdrawn
shall also be withdrawn from registration. If the managing underwriter has not
limited the number of Registrable Shares or other securities to be underwritten,
the Company may include securities for its own account in such registration if
the managing underwriter so agrees and if the number of Registrable Shares and
other securities which would otherwise have been included in such registration
and underwriting will not thereby be limited.

          (d) The Initiating Holders shall have the right to select the managing
underwriter(s) for any underwritten offering initiated by Initiating Holders and
Nortel Networks shall have the right to select the managing underwriter(s) for
any underwritten offering initiated by Nortel Networks pursuant to Section
2.1(a), subject to the approval of the Company, which approval will not be
unreasonably withheld.

          (e) The Company shall not be required to effect, or take any action to
effect, any registration pursuant to this Section 2.1:

               (i) with respect to Stockholders, after the Company has initiated
four (4) registrations requested by Stockholders pursuant to this Section 2.1;

               (ii) with respect to Nortel Networks, after the Company has
initiated one (1) registration requested by Nortel Networks pursuant to this
Section 2.1;

               (iii) subject to the Company's obligations under Section 2.2,
during the period starting with the effective date of the registration statement
and ending on a date one hundred eighty (180) calendar days after the effective
date of a Company-initiated registration.

     For purpose of clauses (i) and (ii) of this Section 2.1(e), a registration
shall not be counted until such time as the related Registration Statement has
been declared or ordered effective by the Commission and (i) the Registration
Statement remains continuously effective for six months or (ii) all Registrable
Shares registered in such registration are sold, if earlier; provided, however,
that a registration shall not be counted if (x) after the related Registration
Statement has become effective, such registration or the related offer, sale or
distribution of Registrable Shares thereunder is interfered with by any stop
order, injunction or other order or requirement of the Commission or other
governmental agency or court for any reason not attributable to the Selling
Stockholders and such interference is not thereafter eliminated, (y) the
conditions specified on the underwriting

                                       7

<PAGE>
agreement, if any, entered into in connection with such Registration Statement
are not satisfied or waived, other than by reason of the Selling Stockholders
or (z) the related Registration Statement is withdrawn by the Selling
Stockholders and the Selling Stockholders have elected to bear all the
Registration Expenses pursuant to Section 2.4 hereof. The time period referred
to in Section 2.3(a)(ii) during which the Registration Statement must be kept
effective shall be extended for an additional number of business days equal to
the number of business days during which the right to sell the Registrable
Shares was interfered with as set forth in the preceding sentence. For purposes
of this Section 2.1(e), a registration shall be counted if the related
Registration Statement is withdrawn by the Stockholders or Nortel Networks, as
applicable, and the Stockholders or Nortel Networks, as applicable, have not
elected to bear the Registration Expenses pursuant to Section 2.4 hereof and
would, absent such election, have been required to bear such expenses. For
purposes of clarification, a registration shall not be counted for purposes of
this Section 2.1(e) if the related Registration Statement is withdrawn by the
Stockholders or Nortel Networks because the Company has taken actions or
suffered any consequences that would have a material adverse effect on the
Company or delay the effectiveness of such Registration Statement (whether
because (i) the Company has elected to delay such Registration Statement
pursuant to the Company's rights hereunder; (ii) there have been negative
developments with respect to the Company that would require disclosure in order
for such Registration Statement to not be misleading, or (iii) otherwise).

          (f) If at the time of any request to register Registrable Shares by
Initiating Holders or Nortel Networks pursuant to this Section 2.1, the Company
is engaged or has plans to engage in a registered public offering or is engaged
in any other activity which, in the good faith determination of the Company's
Board of Directors, would be adversely affected by the requested registration,
then the Company may at its option direct that such request be delayed for a
period not in excess of ninety (90) calendar days from the date of such
request, such right to delay a request to be exercised by the Company not more
than twice in any 12-month period. If after a Registration Statement becomes
effective, the Company advises the Selling Stockholders that the Company
considers it appropriate that the Registration Statement be amended, the
holders of such shares shall suspend any further sales of their Registrable
Shares until the Company advises them that the Registration Statement has been
amended. The time period referred to in Section 2.3(a)(ii) during which the
Registration Statement must be kept effective shall be extended for an
additional number of business days equal to the number of business days during
which the right to sell shares was suspended as set forth in the preceding
sentence.

     2.2 Incidental Registration.

          (a) Whenever the Company proposes to file a Registration Statement
(other than a Registration Statement filed pursuant to Section 2.1 or a
Registration Statement covering shares to be sold solely for the account of
Other Holders) at any time and from time to time after the closing of the
Qualified Initial Public Offering of the Company, it will, prior to such
filing, give written notice to all Stockholders and Nortel Networks holding
Registrable Shares of its intention to do so; provided, that no such notice
need be given if no Registrable Shares are to be included therein as a result
of a determination of the managing underwriter pursuant to Section 2.2(b). Upon
the written request of a Stockholder, Stockholders or Nortel Networks given
within twenty (20) calendar

                                       8

<PAGE>
days after the Company provides such notice (which request shall state the
intended method of disposition of such Registrable Shares), except as set forth
in Section 2.2(b), the Company shall use its best efforts to cause all
Registrable Shares which the Company has been requested by such Stockholder,
Stockholders or Nortel Networks to register to be included in such registration;
provided, that the Company shall have the right to delay, postpone or withdraw
any registration effected pursuant to this Section 2.2 without obligation to any
Stockholder, Nortel Networks or other party; provided, further; that in such
event a Stockholder or Nortel Networks may request a registration in accordance
with Section 2.1, subject to the limitations set forth therein.

          (b)  If the registration for which the Company gives notice pursuant
to Section 2.2(a) is a registered public offering involving an underwriting,
the Company shall so advise the Stockholders and Nortel Networks as a part of
the written notice given pursuant to Section 2.2(a), and, in such event:

               (i) The right of any Stockholder and Nortel Networks to include
its Registrable Shares in such registration pursuant to this Section 2.2 shall
be conditioned upon such Stockholder's or Nortel Networks' participation in such
underwriting.

               (ii) All Stockholders and Nortel Networks proposing to distribute
their securities through such underwriting (together with the Company, Other
Holders and any officers or directors distributing their securities through
such underwriting) shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for the underwriting by the
Company.

               (iii) Notwithstanding any other provision of this Section 2.2, if
the managing underwriter determines that the inclusion of all shares requested
to be registered would adversely affect the offering, the Company may limit the
number of Registrable Shares to be included in the registration and
underwriting. If the underwriter so determines, the Company shall so advise all
Stockholders requesting registration, and the number of shares that are entitled
to be included in the registration and underwriting shall be allocated in the
following manner. The securities of the Company held by officers and directors
of the Company (other than Registrable Shares) shall be excluded from such
registration and underwriting to the extent deemed advisable by the managing
underwriter, and, if a further limitation on the number of shares is required,
the number of shares that may be included in such registration and underwriting
shall be allocated among all Stockholders, Nortel Networks and Other Holders
requesting registration in proportion, as nearly as practicable, to the
respective number of shares of Common Stock (on an as-converted basis) which
they held at the time the Company gives the notice specified in Section 2.2(a),
provided, however, that the number of shares held by Stockholders or Nortel
Networks that may be included in such registration and underwriting may not be
reduced below thirty percent (30%) of any registration and underwriting after
the Qualified Initial Public Offering of the Company. If any Stockholder, Nortel
Networks or Other Holder would thus be entitled to include more securities than
such holder requested to be registered, the excess shall be allocated among
other requesting Stockholders, Nortel Networks and Other Holders pro rata in the
manner described in the preceding sentence. To facilitate the allocation of
shares in accordance with the above provisions, the

                                       9
<PAGE>
Company or the underwriter(s) may round the number of shares allocated to any
person to the nearest 100 shares.

                    (iv) If any Stockholder, Nortel Networks, officer,
director or Other Holder disapproves of the terms of any such underwriting,
such person may elect to withdraw therefrom by written notice to the Company,
and any Registrable Shares or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.

               (c)  Notwithstanding the foregoing, the Company shall not
be required, pursuant to this Section 2.2, to include any Registrable Shares in
a Registration Statement if such Registrable Shares can then be sold pursuant
to Rule 144(k) under the Securities Act; provided, however, that nothing in
this clause (c) shall relieve the Company of its obligations pursuant to
Section 2.2, with respect to any holder of Registrable Shares or any of its
Affiliates, if such holder or any of its Affiliates shall hold, in the
aggregate, five percent (5%) or more of the outstanding equity securities of
the Company.

          2.3 Registration Procedures.

               (a)  If and whenever the Company is required by the provisions
of this Agreement to use its best efforts to effect the registration of any
Registrable Shares under the Securities Act, subject to the Company's right in
the case of a registration under Section 2.2 of this Agreement to delay,
postpone or withdraw any such registration without obligation to any
Stockholder or other party, the Company shall:

                    (i)  file with the Commission a Registration Statement with
respect to such Registrable Shares and use its best efforts to cause that
Registration Statement to become effective as soon as possible; and at least ten
(10) business days before filing a registration statement or prospectus or at
least three (3) business days before filing any amendments or supplements
thereto (in the event of a registration pursuant to Section 2.2 of this
Agreement, the Company shall only have the obligation to provide copies of such
documents within a reasonable period of time prior to any such filing), the
Company will furnish counsel of the holders of a majority of the Registrable
Shares being registered copies of all documents proposed to be filed for that
counsel's review and approval, which approval shall not be unreasonably withheld
or delayed;

                    (ii) as expeditiously as possible prepare and file with the
Commission any amendments and supplements to the Registration Statement and the
prospectus included in the Registration Statement as may be necessary to comply
with the provisions of the Securities Act (including the anti-fraud provisions
thereof) and to keep the Registration Statement effective for six (6) months
from the effective date or such lesser period until all such Registrable Shares
are sold;

                    (iii) as expeditiously as possible furnish to each Selling
Stockholder such reasonable numbers of copies of the Prospectus, including any
preliminary Prospectus, in conformity with the requirements of the Securities
Act, and such other documents as such Selling

                                       10
<PAGE>
Stockholder may reasonably request in order to facilitate the public sale or
other disposition of the Registrable Shares owned by such Selling Stockholder
and included in a registration pursuant to Section 2.1 or Section 2.2;

               (iv) as expeditiously as possible use its best efforts to
register or qualify the Registrable Shares covered by the Registration Statement
under the securities or Blue Sky laws of such states as the Selling Stockholders
shall reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the Selling Stockholders to consummate the
public sale or other disposition in such states of the Registrable Shares owned
by the Selling Stockholder and included in a registration pursuant to Section
2.1 or Section 2.2; provided, however, that the Company shall not be required in
connection with this paragraph (iv) to qualify as a foreign corporation or
execute a general consent to service of process in any jurisdiction;

               (v) as expeditiously as possible, cause all such Registrable
Shares to be listed on each securities exchange or automated quotation system on
which similar securities issued by the Company are then listed;

               (vi) promptly provide a transfer agent and registrar for all such
Registrable Shares not later than the effective date of such registration
statement;

               (vii) promptly make available for inspection by the Selling
Stockholders, any managing underwriter participating in any disposition
pursuant to such Registration Statement, and any attorney or accountant or
other agent retained by any such underwriter or selected by the Selling
Stockholders, all financial and other records and pertinent corporate documents
and properties of the Company and cause the Company's officers, directors,
employees and independent accountants to supply all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in
connection with such Registration Statement;

               (viii) as expeditiously as possible, notify each Selling
Stockholder, promptly after it shall receive notice thereof, of the time when
such Registration Statement has become effective or a supplement to any
Prospectus forming a part of such Registration Statement has been filed;

               (ix) as expeditiously as possible following the effectiveness of
such Registration Statement, notify each Selling Stockholder of (A) any request
by the Commission for the amending or supplementing of such Registration
Statement or Prospectus and (B) any event as a result of which the Prospectus
or any document incorporated therein by reference contains, to the Company's
knowledge, an untrue statement of a material fact or omits to state any
material fact necessary to make the statements therein not misleading, and, in
either case, prepare a supplement or amendment to the Prospectus or any such
document incorporated therein so that thereafter the Prospectus will not
contain, to the Company's knowledge, any untrue statement of a material fact or
omit to state any material fact necessary to make the statements therein not
misleading;

                                       11
<PAGE>
          (x) use its best efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as
soon as reasonably practicable, an earnings statement complying with the
provisions of Section 11(a) of the Securities Act;

          (xi) cooperate with each Selling Stockholder and each underwriter
participating in the disposition of such Registrable Shares and their respective
counsel in connection with any filings required to be made with the National
Association of Securities Dealers, Inc. (the "NASD");

          (xii) immediately notify each Selling Stockholder of any stop order
threatened or issued by the Commission and take all actions reasonably required
to prevent the entry of a stop order or if entered to have it rescinded or
otherwise removed; and

          (xiii) take all other steps reasonably necessary to effect the
registration of the Registrable Shares contemplated hereby.

         (b) If the Company has delivered a Prospectus to the Selling
Stockholders and after having done so the Prospectus is amended to comply with
the requirements of the Securities Act, the Company shall promptly notify the
Selling Stockholders and, if requested, the Selling Stockholders shall
immediately cease making offers of Registrable Shares and return all
Prospectuses to the Company. The Company shall promptly provide the Selling
Stockholders with revised Prospectuses and, following receipt of the revised
Prospectuses, the Selling Stockholders shall be free to resume making offers of
the Registrable Shares. The time period referred to in Section 2.3(a)(ii) during
which the Registration Statement must be kept effective shall be extended for an
additional number of business days equal to the number of business days during
which the right to sell shares was suspended as set forth in this paragraph (b).

         (c) In the event that, in the judgment of the Company, it is advisable
to suspend use of a Prospectus included in a Registration Statement due to
pending material developments or other events that have not yet been publicly
disclosed and as to which the Company believes public disclosure would be
detrimental to the Company, subject to the reporting and disclosure requirements
under the securities laws, the Company, subject to the reporting and disclosure
requirements under the securities laws, the Company shall notify all Selling
Stockholders to such effect, and, upon receipt of such notice, each such Selling
Stockholder shall immediately discontinue any sales of Registrable Shares
pursuant to such Registration Statement until such Selling Stockholder has
received copies of a supplemented or amended Prospectus or until such Selling
Stockholder is advised in writing by the Company that the then current
Prospectus may be used and has received copies of any additional or supplemental
filings that are incorporated or deemed incorporated by reference in such
Prospectus. The time period referred to in Section 2.3(a)(ii) during which the
Registration Statement must be kept effective shall be extended for an
additional number of business days equal to the number of business days during
which the right to sell shares was suspended as set forth in the preceding
sentence.

                                       12
<PAGE>
     2.4  Registration Expenses. The Company will pay all Registration Expenses
for all registrations under this Agreement. For purposes of this Section, the
term "Registration Expenses" shall mean all expenses incident to the Company's
performance of or compliance with this Agreement, including, without
limitation: all registration and filing fees; exchange listing fees; NASD
registration and filing fees; printing expenses; messenger, telephone and
delivery expenses; fees and expenses of counsel for the Company and the fees
and expenses of one counsel selected by the Selling Stockholders to represent
the Selling Stockholders; state Blue Sky fees and expenses; and the expense of
any special audits incident to or required by any such registration; provided,
that Registration Expenses shall exclude all underwriting discounts, selling
commissions and the fees and expenses of Selling Stockholders' own counsel
(other than the counsel selected to represent all Selling Stockholders).

     2.5  Indemnification and Contribution.

          (a)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless the Selling Stockholders, each underwriter of Registrable
Shares hereunder, and each other person, if any, who controls such Selling
Stockholders or underwriter within the meaning of the Securities Act or the
Exchange Act against any losses, claims, damages or liabilities, joint or
several, to which such Selling Stockholders, underwriter or controlling person
may become subject under the Securities Act, the Exchange Act, state securities
or Blue Sky laws or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement under which such Registrable Shares were registered
under the Securities Act, any preliminary prospectus or final prospectus
contained in the Registration Statement, or any amendment or supplement to such
Registration Statement, or arise out of or are based upon the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; and the Company will
reimburse such Selling Stockholders, underwriter and each such controlling
person for any legal or any other expenses reasonably incurred by such Selling
Stockholders, underwriter or controlling person in connection with investigating
or defending any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case to the extent that
any such loss, claim, damage or liability arises out of or is based upon any
untrue statement or omission or alleged untrue statement or omission made in
such Registration Statement, preliminary prospectus or prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of such Selling
Stockholders, underwriter or controlling person specifically for use in the
preparation thereof.

          (b)  In the event of any registration of any of the Registrable
Shares under the Securities Act pursuant to this Agreement, each Selling
Stockholder, severally and not jointly, will indemnify and hold harmless the
Company, each of its directors and officers, each other Selling Stockholder
and each underwriter (if any) and each person, if any, who controls the
Company, each other Selling Stockholder or any such underwriter within the
meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages or liabilities, joint or several, to which the

                                       13

<PAGE>
Company, such directors and officers, each other Selling Stockholder,
underwriter or controlling person may become subject under the Securities Act,
Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement under which such
Registrable Shares were registered under the Securities Act, any preliminary
prospectus or final prospectus contained in the Registration Statement, or any
amendment or supplement to the Registration Statement, or arise out of or are
based upon any omission or alleged omission to state a material fact required to
be stated therein or necessary to make the statements therein not misleading, if
the statement or omission was made in reliance upon and in conformity with
information relating to such Selling Stockholder furnished in writing to the
Company by or on behalf of such seller specifically for use in connection with
the preparation of such Registration Statement, prospectus, preliminary
prospectus, amendment or supplement; provided, however, that the obligations of
a Selling Stockholder hereunder shall be limited to an amount equal to the net
proceeds to such Selling Stockholder from the sale of Registrable Shares sold in
connection with such registration.

          (c) Each party entitled to indemnification under this Section (the
"INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section except to the extent that the Indemnifying Party
is materially adversely affected by such failure. The Indemnified Party may
participate in such defense at such party's expense; provided, however, that the
Indemnifying Party shall pay such expense 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 the Indemnified Party and
any other party represented by such counsel in such proceeding; provided,
further, that in no event shall the Indemnifying Party be required to pay the
expenses of more than one law firm per jurisdiction as counsel for the
Indemnified Party. The Indemnifying Party also shall be responsible for the
reasonable expenses of such defense if the Indemnifying Party does not elect to
assume such defense. No Indemnifying Party, in the defense of any such claim or
litigation shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect of such claim or
litigation. 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 includes any
non-monetary remedies. No Indemnified Party shall consent to entry of any
judgment or settle such claim or litigation without the prior written consent of
the Indemnifying Party, which consent shall not be unreasonably withheld.

                                       14

<PAGE>
          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Section 2.5 is
due in accordance with its terms but for any reason is held to be unavailable to
an Indemnified Party in respect to any losses, claims, damages and liabilities
referred to herein, then the Indemnifying Party shall, in lieu of indemnifying
such Indemnified Party, contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities to
which such party may be subject in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the Stockholders on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Selling Stockholders
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of material fact related to information supplied by the
Company or the Selling Stockholders and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Selling Stockholders agree that it would not be
just and equitable if contribution pursuant to this Section 2.5 were determined
by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to above.

          (e) Notwithstanding the provisions of this Section 2.5, in no case
shall any one Selling Stockholder be liable or responsible for an amount in
excess of the net proceeds received by such Selling Stockholder from the
offering of Registrable Shares; provided, however, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this Section, notify such party
or parties from whom contribution may be sought, but the omission so to notify
such party or parties from whom contribution may be sought shall not relieve
such party from any other obligation it or they may have thereunder or otherwise
under this section. No party shall be liable for contribution with respect to
any action, suit, proceeding or claim settled without its prior written consent,
which consent shall not be unreasonably withheld.

          (f) Notwithstanding any provision in this Agreement, to the extent
that the provisions on indemnification and contribution contained in the
underwriting agreement entered into in connection with the underwritten public
offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.

     2.6  Other Matters with Respect to Underwritten Offerings. In the event
that Registrable Shares are sold pursuant to a Registration Statement in an
underwritten offering pursuant to Section 2.1, the Company agrees to: (a) enter
into an underwriting agreement containing customary representations and
warranties with respect to the business and operations of the Company and
customary covenants and agreements to be performed by the Company, including
without limitation customary provisions with respect to indemnification by the
Company of the underwriters of such offering; (b) use its best efforts to cause
its legal counsel to render customary opinions to the underwriters with respect
to the Registration Statement; and (c) use its best efforts to

                                       15

<PAGE>
cause its independent public accounting firm to issue customary "cold comfort
letters" to the underwriters with respect to the Registration Statement. No
underwriting agreement will result in liability of a Stockholder or Nortel
Networks in excess of the net proceeds from the offering received by such
Stockholder or Nortel Networks, including any liability under Section 2.5 of
this Agreement.

          2.7 Information by Holder. Each Selling Stockholder shall furnish to
the Company such information regarding such holder and the distribution proposed
by such holder as the Company may reasonably request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Agreement.

          2.8 "Stand-Off" Agreement; Confidentiality of Notices. Each
Stockholder and Nortel Networks, if requested by the Company or the managing
underwriter of an underwritten public offering by the Company of Common Stock,
shall not sell or otherwise transfer or dispose of any Registrable Shares or
other securities of the Company held by such person for a period of one hundred
eighty (180) calendar days following the effective date of a Registration
Statement, provided, that, (a) such agreement shall only apply to the Qualified
Initial Public Offering of the Company, and (b) all Stockholders of the Company
then holding at least 1% of the outstanding Common Stock (on an as converted
basis) and all officers and directors of the Company enter or have entered into
similar agreements. Compliance with such agreements may not be waived except to
the extent it is waived in the same manner for each of the Stockholders and
Nortel Networks.

     The Company may impose stop-transfer instructions with respect to the
Registrable Shares or other securities subject to the foregoing restriction
until the end of such 180-day period. Any Stockholder and/or Nortel Networks
receiving any written notice from the Company regarding the Company's plans to
file a Registration Statement shall treat such notice confidentially and shall
not disclose such information to any person other than as necessary to exercise
its rights under this Agreement. Each Stockholder and Nortel Networks agrees to
execute a market standoff agreement with said underwriters in customary form
consistent with the provisions of this Section 2.8, provided, that all
Stockholders of the Company holding at least 1% of the outstanding Common Stock
(on an as converted basis) and all officers and directors of the Company enter
or have entered into similar agreements. Compliance with the agreements subject
to this paragraph may not be waived except to the extent it is waived in the
same manner for each of the Stockholders and Nortel Networks.

          2.9 Limitations on Subsequent Registration Rights. The Company shall
not, without the prior written consent of (i) Nortel Networks and (ii) the
holders of at least 50% of the Registrable Shares then held by the
Stockholders, enter into any agreement (other than this Agreement) with any
holder or prospective holder of any securities of the Company which grant such
holder or prospective holder rights to include securities of the Company in any
Registration Statement, unless: (a) such rights to include securities in a
registration initiated by the Company, Stockholders or Nortel Networks pursuant
hereto are not more favorable than the rights granted to Other Holders under
Sections 2.1 and 2.2 of this Agreement, and (b) no rights are granted to
initiate a registration, other than registration pursuant to a registration
statement on Form S-3 (or its successor) in which

                                       16
<PAGE>
Stockholders or Nortel Networks are entitled to include Registrable Shares on a
pro rata basis with such holders based on the number of shares of Common Stock
(on an as-converted basis) owned by Stockholders, Nortel Networks and such
holders. Nortel Networks' rights under this Section 2.9 will terminate the later
of such time as when the Company's obligations under the Nortel Note are
cancelled, or Nortel Networks no longer holds any shares of Common Stock of the
Company issuable pursuant to the Nortel Note.

          2.10 Rule 144 Requirements. After the earliest of (i) the closing of
the sale of securities of the Company pursuant to a Registration Statement, (ii)
effectiveness of the registration by the Company of a class of securities under
Section 12 of the Exchange Act, or (iii) the issuance by the Company of an
offering circular pursuant to Regulation A under the Securities Act, the Company
agrees to:

available, as those terms are understood and defined in Rule 144;

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

               (c) furnish to any holder of Registrable Shares upon request (i)
a written statement by the Company as to its compliance with the reporting
requirements of Rule 144 (at any time from and after ninety (90) calendar days
following the date on which the Company became subject to the reporting
requirements of Section 13 of the Securities Act) and of the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements), (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents of the Company as such
holder may reasonably request to avail itself of any similar rule or regulation
of the Commission allowing it to sell any such securities without registration.

          2.11 Transfer or Assignment of Registration Rights. The rights to
cause the Company to register securities granted to a Stockholder or Nortel
Networks by the Company under this Section 2 may be transferred or assigned, in
whole or in part, by a Stockholder or Nortel Networks in connection with the
transfer of Registrable Shares, and only with respect thereto, only to (i) a
transferee or assignee of not less than 500,000 shares of Registrable Shares (as
presently constituted and subject to subsequent adjustments for stock splits,
stock dividends, reverse stock splits and the like), (ii) any constituent
partner or stockholder of such Stockholder or Nortel Networks, (iii) any
venture capital fund or investment entity for which such Stockholder or Nortel
Networks or their respective successors or assigns is the investment manager or
advisor or (iv) if such Stockholder is a corporation, a wholly owned subsidiary
of such corporation or a wholly owned subsidiary of Nortel Networks, or in a
distribution to its stockholders; provided, that the Company is given written
notice at the time or within a reasonable time after said transfer or
assignment, stating the name and address of the transferee or assignee and
identifying the securities with respect to which such registration rights are
being transferred or assigned, and, provided, further, that the transfer or
assignment of the Registrable Shares is in compliance with the restrictions on
transfer set

                                       17
<PAGE>
forth in Section 7 of this Agreement, and the transferee or assignee of such
shares and rights assumes in writing the obligations of such Stockholder or
Nortel Networks under this Section 2.

          2.12 Termination.  All of the Company's obligations to register
Registrable Shares under Sections 2.1 and 2.2 of this Agreement shall terminate
upon the earlier of:

                  (a)  three years after the closing of the Qualified Initial
Public Offering of the Company;

                  (b)  with respect to the rights of any Stockholder under
Section 2.1, at any time such Stockholder does not own in the aggregate at least
100,000 Registrable Shares; or

                  (c)  with respect to the rights of any Stockholder under
Section 2.2, on the date all shares of Registrable Shares held or entitled to be
held upon conversion by such parties may immediately be sold under Rule 144
during any ninety (90) day period; provided that after such date the Company
will have the obligation to register Registrable Shares held by such Stockholder
under Section 2.2 of this Agreement (subject to the limitations and
qualifications therein and elsewhere in this Agreement) if and only for so long
as such Stockholder is prohibited from making sales pursuant to Rule 144 solely
because of the failure of the Company to satisfy Rule 144(c); provided, further,
however, that nothing in this clause (c) shall relieve the Company of its
obligations to register Registrable Shares under Section 2.2, with respect to
any holder of Registrable Shares or any of its Affiliates, if such holder or any
of its Affiliates shall hold, in the aggregate, five percent (5%) or more of the
outstanding equity securities of the Company.

     3.  PREEMPTIVE RIGHTS OF STOCKHOLDERS WITH RESPECT TO CERTAIN ISSUANCES OF
SECURITIES BY THE COMPANY.

          3.1  Preemptive Rights of Stockholders.

                  (a)  Subject to the exceptions set forth in Section 3.1(g) of
this Agreement, the Company shall not issue, sell or exchange, enter into a
binding agreement to issue, sell or exchange, or reserve or set aside for
issuance, sale or exchange: (i) any shares of its Common Stock, (ii) any other
equity securities of the Company, including, without limitation, shares of
Preferred Stock, (iii) any option, warrant or other right to subscribe for,
purchase or otherwise acquire any equity securities of the Company, or (iv) any
debt securities convertible into capital stock of the Company (collectively, the
"COMPANY OFFERED SECURITIES"), unless in each such case the Company shall have
first complied with this Section 3.1. The Company shall deliver to each
Stockholder a written notice of any proposed or intended issuance, sale or
exchange of the Company Offered Securities (the "COMPANY OFFER"), which Company
Offer shall: (i) identify and describe the Company Offered Securities, (ii)
describe the price and other terms upon which they are to be issued, sold or
exchanged, and the number or amount of the Company Offered Securities to be
issued, sold or exchanged, (iii) identify the persons or entities (if known) to
which or with which the Company Offered Securities are to be offered, issued,
sold or exchanged and (iv) offer to issue, sell or exchange with such
Stockholders: (A) a pro rata portion of the Company Offered Securities

                                       18
<PAGE>

determined by dividing (x) the aggregate number of shares of Common Stock then
held by such Stockholder (giving effect to the conversion of all outstanding
shares of Preferred Stock then held) by (y) the total number of shares of
Common Stock then outstanding (giving effect to the conversion of all
outstanding shares of Preferred Stock then held) (such pro rata portion of the
Company Offered Securities, the "BASIC AMOUNT"), and (B) any additional portion
of the Company Offered Securities as such Stockholder shall indicate it will
purchase or acquire should the other Stockholders subscribe for less than their
Basic Amounts (the "UNDERSUBSCRIPTION AMOUNT").

          (b) To accept a Company Offer, in whole or in part, a Stockholder must
deliver a written notice to the Company prior to the end of the fifteen (15) day
period of the Company Offer, setting forth the portion of the Stockholder's
Basic Amount that such Stockholder elects to purchase and, if such Stockholder
shall elect to purchase all of its Basic Amount, the Undersubscription Amount
(if any) that such Stockholder elects to purchase (the "NOTICE OF ACCEPTANCE").
If the Basic Amounts subscribed for by all Stockholders are less than the total
of all of the Basic Amounts available for purchase, then each Stockholder who
has set forth an Undersubscription Amount in its Notice of Acceptance shall be
entitled to purchase, in addition to the Basic Amounts subscribed for, the
Undersubscription Amount it has subscribed for; provided, however, that if the
Undersubscription Amounts subscribed for exceed the difference between the total
of all of the Basic Amounts available for purchase and the Basic Amounts
subscribed for (the "AVAILABLE UNDERSUBSCRIPTION AMOUNT"), each Stockholder who
has subscribed for any Undersubscription Amount shall be entitled to purchase
only that portion of the Available Undersubscription Amount as the
Undersubscription Amount subscribed for by such Stockholder bears to the total
Undersubscription Amounts subscribed for by all Stockholders, subject to
rounding by the Company to the extent it deems reasonably necessary.

          (c) The Company shall have ninety (90) calendar days from the
expiration of the period set forth in Section 3.1(b) above to issue, sell or
exchange all or any part of such Company Offered Securities as to which a Notice
of Acceptance has not been given by the Stockholders (the "REFUSED SECURITIES"),
but only to the offerees or purchasers described in the Company Offer (if so
described therein) and only upon terms and conditions (including, without
limitation, unit prices and interest rates) which are not materially more
favorable, in the aggregate, to the acquiring person or persons or materially
less favorable to the Company than those set forth in the Company Offer. In the
event the Company has not sold the Refused Securities within such ninety (90)
day period, the Company shall not thereafter issue or sell any Refused
Securities, without first again offering such securities to the Stockholders in
accordance with this Section 3.

          (d) In the event the Company shall propose to sell less than all the
Refused Securities (any such sale to be in the manner and on the terms
specified in Section 3.1(c) above), then each Stockholder may, at its sole
option and in its sole discretion, reduce the number or amount of the Company
Offered Securities specified in its Notice of Acceptance to an amount that
shall be not less than the number or amount of the Company Offered Securities
that the Stockholder elected to purchase pursuant to Section 3.1(b) above
multiplied by a fraction, (i) the numerator of which shall be the number or
amount of Company Offered Securities the Company actually proposes to issue,
sell or exchange (including Company Offered Securities to be issued or sold to
Stockholders

                                       19

<PAGE>
pursuant to Section 3.1(b) above prior to such reduction) and (ii) the
denominator of which shall be the original amount of the Company Offered
Securities. In the event that any Stockholder so elects to reduce the number or
amount of Company Offered Securities specified in its Notice of Acceptance, the
Company may not issue, sell or exchange more than the reduced number or amount
of the Company Offered Securities unless and until such securities have again
been offered to the Stockholders that have provided a Notice of Acceptance in
accordance with Section 3.1(a) and Section 3.1(b) above.

          (e) Upon the closing of the issuance, sale or exchange of all or less
than all of the Refused Securities, the Stockholders shall acquire from the
Company, and the Company shall issue to the Stockholders, the number or amount
of the Company Offered Securities specified in the Notices of Acceptance, as
reduced pursuant to Section 3.1(d) above if the Stockholders have so elected,
upon the terms and conditions specified in the Company Offer. The purchase by
the Stockholders of any Company Offered Securities is subject in all cases to
the preparation, execution and delivery by the Company and the Stockholders of a
purchase agreement relating to such Company Offered Securities reasonably
satisfactory in form and substance to the Company and respective Stockholders,
and their respective counsel.

          (f) Any Company Offered Securities not acquired by the Stockholders
or other persons in accordance with Section 3.1(c) above within the time
periods specified therein may not be issued, sold or exchanged until they are
again offered to the Stockholders under the procedures specified in this
Section 3.

          (g) The Company Offered Securities shall not include, and the rights
of the Stockholders under this Section 3 shall not apply to, the offer, sale,
issuance or exchange of the following securities by the Company or any of its
subsidiaries:

               (1) securities purchased under the Series C Preferred Stock
Purchase Agreement, of even date herewith;

               (2) shares of Common Stock issued or issuable upon conversion of
shares of Preferred Stock of the Company;

               (3) shares of Common Stock or the grant of options therefor,
including shares issued upon exercise of options outstanding on the date of
this Agreement (such number to be proportionately adjusted in the event of any
stock splits, stock dividends, recapitalizations or similar events occurring on
or after the date of this Agreement), or issued pursuant to any stock option
exchange program (approved by the affirmative vote or consent of at least sixty
percent (60%) of the shares of Preferred Stock then outstanding), to directors,
officers, employees, consultants or advisors of the Company or any subsidiary
pursuant to any plan, agreement or arrangement approved by the Board of
Directors of the Company;

                                       20
<PAGE>
                  (4) securities issued or issuable directly in consideration
for the acquisition of another corporation by the Company by merger, purchase of
all or substantially all of the assets or other reorganization;

                  (5) shares of Common Stock sold by the Company in an
underwritten public offering pursuant to an effective registration statement
under the Securities Act;

                  (6) shares of Common Stock issued or issuable upon the
exercise of any options or warrants or other rights to subscribe for, purchase
or otherwise acquire any equity securities of the Company;

                  (7) shares of Common Stock issued or issuable as a dividend or
distribution on Preferred Stock or pursuant to any event for which adjustment is
made pursuant to Article IV, Section 4(e), (f), (g) and (h) of the Company's
Amended and Restated Certificate of Incorporation, as amended;

                  (8) securities issued or issuable to banks, equipment lessors
or other financial institutions pursuant to a commercial leasing or debt
financing transaction approved by the Board of Directors of the Company;

                  (9) shares of Common Stock or Preferred Stock which are
otherwise excluded by the affirmative vote or consent of the holders of at least
sixty percent (60%) of the shares of Preferred Stock then outstanding;

                  (10) securities issued to strategic investors as opposed to
financial investors and which are approved by the Board of Directors of the
Company;

                  (11) any right, option or warrant to acquire any security
convertible into the securities excluded from the definition of Company Offered
Securities pursuant to this Section 3.1(g);

                  (12) any shares of Common Stock issued or issuable upon
conversion of the Nortel Note; and

                  (13) those certain Common Stock warrant agreements, dated as
of the date hereof, issued by the Company to Shamrock Capital Advisors, Inc. or
its affiliates ("SHAMROCK") for services rendered to the Company (the "SHAMROCK
WARRANTS") or any shares of Common Stock issued or issuable upon exercise or
otherwise with respect to the Shamrock Warrants.

     (h)  The failure of any Stockholder to exercise its rights under this
Section 3 shall not be deemed to be a waiver of its rights hereunder in
connection with any subsequent issuance, sale or exchange of Company Offered
Securities.

                                       21
<PAGE>
          3.2 Transfer or Assignment of Preemptive Rights. The preemptive
rights set forth in this Section 3 may be transferred or assigned, in whole or
in part, by a Stockholder in connection with the transfer of Shares, and only
with respect thereto, only to (i) a transferee or assignee of not less than
500,000 Shares (as presently constituted and subject to subsequent adjustments
for stock splits, stock dividends, reverse stock splits and the like), (ii) any
constituent partner or stockholder of such Stockholder, (iii) any venture
capital fund or investment entity (or any successor thereof) for which such
Stockholder or their respective successors or assigns is the investment manager
or advisor or (iv) if such Stockholder is a corporation, a wholly owned
subsidiary of such corporation or in a distribution to its stockholders;
provided, that the Company is given written notice at the time or within a
reasonable time after said transfer or assignment, stating the name and address
of the transferee or assignee and identifying the securities with respect to
which such preemptive rights are being transferred or assigned, and, provided,
further, that the transfer or assignment of the Shares is in compliance with
the restrictions on transfer set forth in Section 7 of this Agreement, and the
transferee or assignee of such shares and rights assumes in writing the
obligations of such Stockholder under this Section 3.

          3.3 Termination. The rights and obligations granted pursuant to this
Section 3 shall terminate upon the earlier of the following events (provided
that the provisions of this Section 3 shall not apply to any sale of Shares
pursuant to a transaction referred to in Sections 3.3(a) or 3.3(b) herein):

               (a) the sale of all or substantially all of the assets or
business of the Company, by merger, sale of assets or otherwise (except a merger
or consolidation in which the holders of capital stock of the Company
immediately prior to such merger or consolidation continue to hold immediately
following such merger or consolidation at least 50% by voting power of the
capital stock of the surviving corporation);

               (b) the closing of a Qualified Initial Public Offering of shares
of the Company; or

               (c) with respect to any Stockholder, at any time that such
Stockholder does not own in the aggregate at least 100,000 shares.

     4. MUTUAL RIGHTS OF FIRST REFUSAL AND CO-SALE RIGHTS AMONG THE
STOCKHOLDERS. As used in this Section 4, the term "Shares" shall include all
shares of capital stock of the Company held by the Stockholders, respectively,
whether now owned or hereafter acquired. For purposes of calculating any
Stockholder's "pro rata" ownership of Shares, all shares of Preferred Stock of
the Company shall be deemed to have been converted into Common Stock of the
Company.

          4.1 Offer of Sale; Notice of Proposed Sale. If a Stockholder desires
to transfer any of his, her or its Shares, or any interest in such Shares, in
any transaction, other than pursuant to a Permitted Transfer or otherwise
pursuant to Section 4 of this Agreement, such person or entity (the "SELLING
PARTY") shall first deliver written notice of his, her or its desire to do so
(the "STOCKHOLDER SALE NOTICE") to the Company and each of the other
Stockholders (collectively, the "NON-SELLING

                                       22

<PAGE>
PARTIES"). The Stockholder Sale Notice must specify: (i) the number of Shares
the Selling Party proposes to sell or otherwise dispose of (the "STOCKHOLDER
OFFERED SHARES"), (ii) the consideration per Share to be delivered to the
Selling Party for the proposed sale, transfer or disposition of the Stockholder
Offered Shares, and (iii) all other material terms and conditions of the
proposed transaction.

     4.2 Non-Selling Parties' Option to Purchase.

                  (a) Subject to Section 4.3(a), each Non-Selling Party shall
have the option, exercisable for a period of fifteen (15) calendar days from the
date of delivery of the Stockholder Sale Notice, to purchase, on a pro rata
basis according to the number of Shares owned by such Non-Selling Party, the
Stockholder Offered Shares for the consideration per share and on the terms and
conditions set forth in the Stockholder Sale Notice. Such option shall be
exercised by delivery by such Non-Selling Party of written notice to the Selling
Party and the Secretary of the Company. Alternatively, each Non-Selling Party
may, within the same fifteen (15) day period, notify the Selling Party and the
Secretary of the Company of its desire to participate pro rata in the sale of
the Shares (which sale may be conditioned upon the failure of the Non-Selling
Parties to fully exercise their options to purchase the Stockholder Offered
Shares) on the terms set forth in the Stockholder Sale Notice, and the number of
Shares it wishes to sell. Such Non-Selling Party may participate in the sale of
Shares up to a number of Shares of the Company equal to (its "PRO RATA SHARE")
the product of (x) the number of Stockholder Offered Shares times (y) the
quotient obtained by dividing (i) the number of Shares (on a fully-diluted
basis) owned by such Non-Selling Party, by (ii) the number of Shares (on a
fully-diluted basis) of the Company owned by all Stockholders, including the
Selling Parties, who have elected to participate in the proposed sale of Shares,
immediately prior to the transfer of the Stockholder Offered Shares to the
proposed transferee(s). If such Non-Selling Parties elect to participate in such
transfer, the Selling Party shall use his, her or its best efforts to obtain the
agreement of the prospective transferee(s) to the participation of such
Non-Selling Parties in any proposed transfer and shall not transfer any shares
of the capital stock of the Company to such prospective transferee(s) unless
such prospective transferee(s) allow(s) the participation of such Non-Selling
Parties on the terms specified in the Stockholder Sale Notice.

                  (b) In the event options to purchase have been exercised by
the Non-Selling Parties with respect to some but not all of the Stockholder
Offered Shares, those Non-Selling Parties who have exercised their options
within the fifteen (15) day period specified in Section 4.2(a) shall have an
additional option (and shall be so notified by the Selling Party prior to the
end of such fifteen (15) day period), for a period of five (5) calender days
next succeeding the expiration of such fifteen (15) day period, to purchase all
or any part of the balance of such Stockholder Offered Shares (the "REMAINING
SHARES") on the terms and conditions set forth in the Stockholder Sale Notice,
which option shall be exercised by the delivery of a written notice to the
Selling Party and the Secretary of the Company. In the event there are two or
more such Non-Selling Parties that choose to exercise the last-mentioned option
for a total number of Remaining Shares in excess of the number available, the
Remaining Shares available for each such Non-Selling Party's option shall be
allocated to such Non-Selling Party pro rata based on the number of Shares owned
by the Non-Selling Parties so electing.

                                       23
<PAGE>
               (c)  If the options to purchase the Stockholder Offered Shares
are exercised in full by the Non-Selling Parties, the Selling Party and the
Company shall immediately notify all of the exercising Non-Selling Parties of
that fact. The closing of the purchase of the Stockholder Offered Shares shall
take place at the offices of the Company no later than five (5) calendar days
after the date of such notice to the Non-Selling Parties.

          4.3 Failure to Fully Exercise Options.

               (a)  If the Non-Selling Parties do not exercise their options to
purchase all of the Stockholder Offered Shares within the periods described in
this Agreement (the "OPTION PERIOD"), then all options of the Non-Selling
Parties to purchase the Remaining Shares not purchased by the Non-Selling
Parties shall terminate, and the Selling Party shall be free to sell such
shares to third parties.

               (b)  If the Selling Party wishes to transfer any such Shares at
a price per Share which differs from that set forth in the Stockholder Sale
Notice, upon terms different from those previously offered to the Stockholders,
or more than sixty (60) calender days after the expiration of the Option
Period, then, as a condition precedent to such transaction, such Shares must
first by offered to the Non-Selling Parties, on the same terms and conditions
given the offeror and in accordance with the procedures and time periods set
forth above.

               (c)  The proceeds of any sale made by the Selling Party without
compliance with the provisions of this Section 4.3 shall be deemed to be held
in constructive trust in such amount as would have been due the participating
Stockholders if the Selling Party had complied with this Agreement. Any attempt
to transfer Shares in violation of Sections 4.1, 4.2 or 4.3 of this Agreement
shall be void and the Company agrees that it will not effect such a transfer
nor will it treat any alleged transferee as the holder of such Shares.

          4.4 Transfer or Assignment of Right of First Refusal and Co-Sale
Rights. The right of first refusal and co-sale rights set forth in this Section
4 may be transferred or assigned, in whole or in party, by a Stockholder in
connection with the transfer of Shares, and only with respect thereto, only to
(i) a transferee or assignee of not less than 500,000 Shares (as presently
constituted and subject to subsequent adjustments for stock splits, stock
dividends, reverse stock splits and the like), (ii) any constituent partner or
stockholder of such Stockholder, (iii) any venture capital fund or investment
entity (or any successor thereof) for which such Stockholder or their
respective successors or assigns is the investment manager or advisor or (iv)
if such Stockholder is a corporation, a wholly owned subsidiary of such
corporation or in a distribution to its stockholders; provided, that the
Company is given written notice at the time or within a reasonable time after
said transfer or assignment, stating the name and address of the transferee or
assignee and identifying the securities with respect to which such right of
first refusal and co-sale rights are being transferred or assigned, and,
provided, further, that the transfer or assignment of the Shares is in
compliance with the restrictions on transfer set forth in Section 7 of this
Agreement, and the transferee or assignee of such shares and rights assumes in
writing the obligations of such Stockholder under this Section 4.

                                       24

<PAGE>
          4.5   Termination of Right of First Refusal and Co-Sale Rights. The
rights and obligations granted pursuant to this Section 4 shall terminate upon
the earlier of the following events (provided that the provisions of this
Section 4 shall not apply to any sale of Shares pursuant to a transaction
referred to in Sections 4.5(a) or 4.5(b) herein):

               (a)  the sale of all or substantially all of the assets or
business of the Company, by merger, sale of assets or otherwise (except a
merger or consolidation in which the holders of capital stock of the Company
immediately prior to such merger or consolidation continue to hold immediately
following such merger or consolidation at least seventy five percent (75%) by
voting power of the capital stock of the surviving corporation); or

               (b)  the closing of a Qualified Initial Public Offering of
shares of the Company; or

               (c)  with respect to any Stockholder, at any time that such
Stockholder does not own in the aggregate at least 100,000 Shares.

term "Shares" shall include all shares of capital stock of the Company held by
the Stockholders, respectively, whether now owned or hereafter acquired.

          5.1  Inspection Rights. The Company shall permit each Stockholder, as

thereof, reasonable access to visit and inspect the properties of the Company,

          5.2  Financial Statements and Other Information.

in substitution or exchange therefor as provided herein. This Warrant is issued
in consideration for certain advisory and consulting services rendered by the
Holder to the Company.

         1.       Number and Price of Shares.

                  (a)      Number of Shares. The Holder shall have the right to
purchase at any time after the date hereof up to 125,000 Shares (as may be
adjusted pursuant hereto) prior to the expiration of this Warrant as provided in
Section 10 hereof.

<PAGE>

                  (b)      Exercise Price. The exercise price per Share shall be
equal to $2.26 per Share, as adjusted from time to time pursuant to Section 8
hereof (the "EXERCISE PRICE").

         2.       Exercise Of Warrants.

                  (a)      Cash Exercise. The purchase rights represented by
this Warrant may be exercised at the election of the Holder, in whole or in
part, but not for less than five thousand (5,000) Shares at a time (or such
lesser number of shares which may then constitute the maximum number
purchasable) (such number being subject to adjustment as provided in Section 8
hereof), at any time, and from time to time, prior to the expiration of this
Warrant as set forth in Section 10, by (i) the tender to the Company at its
principal office (or such other office or agency of the Company as it may
designate by notice in writing to the Holder at the address of the Holder
appearing on the books of the Company) of a notice of exercise in the form
attached hereto as EXHIBIT A (the "NOTICE OF EXERCISE"), duly completed and
executed on behalf of the Holder, together with the surrender of this Warrant,
and (ii) the payment to the Company of an amount equal to the Exercise Price
multiplied by the number of Shares being purchased by wire transfer or
certified, cashier's or other check acceptable to the Company and payable to the
order of the Company.

                  (b)      Net Issue Exercise. In lieu of exercising this
Warrant pursuant to Section 2(a) above, if the fair market value of one share of
Common Stock is greater than the Exercise Price (at the date of calculation as
set forth below), the Holder may elect to receive a number of Shares equal to
the value of this Warrant (or of any portion thereof remaining unexercised) by
surrender of this Warrant at the principal office of the Company (or such other
office or agency of the Company as it may designate by notice in writing to the
Holder at the address of the Holder appearing on the books of the Company)
together with the properly endorsed Notice of Exercise and notice of such
election, in which event the Company shall issue to the Holder that number of
Shares computed using the following formula:

                  X =  Y (A - B)
                       ---------
                           A

         Where:

         X = the number of Shares to be issued to the Holder;

         Y = the number of Shares purchasable under this Warrant or, if only
             a portion of the Warrant is being exercised, the portion of the
             Warrant being cancelled (at the date of such calculation);

         A = the fair market value of one share of the Shares (at the date of
             such calculation); and

         B = the Exercise Price (as adjusted to the date of such calculation).

         For purposes of the calculation above, the fair market value of one (1)
Share shall be determined by the Board of Directors of the Company, acting in
good faith; provided, however, that where a public market exists for the
Company's Common Stock at the time of such exercise, the fair market value per
share shall be the average of the closing bid and asked prices of the Common
Stock quoted in the Over-The-Counter Market Summary or the last reported sale
price of the Common Stock or the closing price quoted on the Nasdaq National
Market or on any exchange on which the Common Stock is listed, whichever is
applicable, as published in the Wall Street Journal for the twenty (20) trading
day period ending two (2) trading days prior to the date of determination of
fair market value. Notwithstanding the foregoing, in the event the Warrant is
exercised in connection with the Company's initial public offering of Common
Stock, the fair market value per share shall be the per share offering price to
the public of the Company's initial public offering.

                                       2

<PAGE>

                  (c)      Stock Certificates. This Warrant shall be deemed to
have been exercised and the Shares shall be deemed to have been issued
immediately prior to the close of business on the date of its tender for
exercise as provided above, and the person entitled to receive the Shares
issuable upon such exercise shall be treated for all purposes as the holder of
record of such Shares as of the close of business on such date. As promptly as
practicable on or after such date, the Company shall issue and deliver to the
person or persons entitled to receive the same a certificate or certificates for
that number of shares issuable upon such exercise. In the event that this
Warrant is exercised in part and has not expired, the Company shall execute and
deliver a new Warrant with the same terms and conditions for the number of
Shares that remain subject to this Warrant.

                  (d)      Taxes. The Holder shall be responsible for any taxes
arising from the issue and delivery of any certificate in a name other than that
of the Holder, and the Company shall not be required to issue or deliver any
such certificate unless and until the person or persons requesting the issue
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

         3.       No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. In lieu of such fractional share to which the Holder would otherwise be
entitled, the Company shall make a cash payment equal to the Exercise Price
multiplied by such fraction.

         4.       Replacement of Warrant. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and substance to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at the expense of the Holder shall execute and deliver, in lieu of
this Warrant, a new warrant of like tenor and amount.

         5.       Representations and Warranties of the Holder.

                  (a)      No Registration. The Holder understands that this
Warrant and the Shares issuable upon exercise of this Warrant (the "SECURITIES")
have not been, and will not be, registered under the Securities Act of 1933, as
amended (the "SECURITIES ACT") by reason of a specific exemption from the
registration provisions of the Securities Act, the availability of which depends
upon, among other things, the bona fide nature of the investment intent and the
accuracy of the Holder's representations as expressed herein or otherwise made
pursuant hereto.

                  (b)      Investment Intent. The Holder is acquiring the
Securities for investment for its own account, not as a nominee or agent, and
not with the view to, or for resale in connection with, any distribution
thereof.

                  (c)      Investment Experience. The Holder has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests.

                  (d)      Speculative Nature of Investment. The Holder
acknowledges that its investment in the Company is highly speculative and
entails a substantial degree of risk and the Holder is in a position to lose the
entire amount of such investment.

                                       3

<PAGE>

                  (e)      Accredited Investor. The Holder is an "accredited
investor" within the meaning of Regulation D, Rule 501(a), promulgated by the
Securities and Exchange Commission.

                  (f)      Residency. The residency of the Holder is correctly
set forth on the signature page hereto.

                  (g)      Restriction on Resales. The Holder acknowledges that
the Securities must be held indefinitely unless subsequently registered under
the Securities Act or unless an exemption from such registration is available.
The Company has no present intention of registering such Securities. The Holder
further understands that there is no assurance that any exemption from
registration under the Securities Act will be available or, if available, that
such exemption will allow the Holder to dispose of or otherwise transfer any or
all of the Securities under the circumstances, in the amounts or at the times
the Holder might propose.

                  (h)      Authorization.

                           (i)      The Holder has all requisite power and
authority to execute and deliver this Warrant, to purchase the Shares issuable
upon exercise of this Warrant and to carry out and perform its obligations under
the terms and conditions of this Warrant. All action on the part of the Holder
necessary for the authorization, execution, delivery and performance of this
Warrant, and the performance of all of the Holder's obligations under this
Warrant, has been taken or will be taken prior to the purchase of this Warrant.

                           (ii)     This Warrant, when executed and delivered by
the Holder, will constitute a valid and legally binding obligation of the
Holder, enforceable in accordance with its terms except: (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium and other laws of
general application affecting enforcement of creditors' rights generally, and
(ii) as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies or by general principles of
equity.

                           (iii)    No consent, approval, authorization, order,
filing, registration or qualification of or with any court, governmental
authority or third person is required to be obtained by the Holder in connection
with the execution and delivery of this Warrant or the performance of the
Holder's obligations hereunder.

                  (i)      Brokers and Finders. The Holder has not engaged any
brokers, finders or agents in connection with this Warrant, and the Company has
not incurred and will not incur, directly or indirectly, as a result of any
action taken by the Holder, any liability for brokerage or finders' fees or
agents' commissions or any similar charges in connection with this Warrant.

                  (j)      Investor Counsel. The Holder acknowledges that it has
had the opportunity to review this Warrant, the exhibits and schedules attached
thereto and the transactions contemplated by this Warrant with its own legal
counsel. The Holder is relying solely on such counsel and not on any statements
or representations of the Company or its agents for legal advice with respect to
this investment or the transactions contemplated by this Warrant.

                  (k)      Tax Advisors. The Holder has reviewed with its own
tax advisors the U.S. federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Warrant. With respect to
such matters, the Holder relies solely on such advisors and not on any
statements or representations of the Company or any of its agents, written or
oral. The Holder understands that it (and not the Company) shall be responsible
for its own tax liability that may arise as a result of this investment or the
transactions contemplated by this Warrant.

         6.       Transfer of Warrants; Restrictions on Transfer.

                  (a)      Warrant Register. The Company shall maintain a
register (the "WARRANT REGISTER") containing the name and address of the Holder
or Holders. Any Holder of this Warrant or any portion thereof may change its
address as shown on the Warrant Register by written notice to the Company
requesting such change. Any written notice or written communication required or
permitted to be given to the Holder may be delivered or given by any method
provided in Section 11(d) hereof. Until this Warrant is transferred in
compliance with the terms hereof, the Company may treat the Holder as shown on
the Warrant Register as the absolute owner of this Warrant for all purposes,
notwithstanding any notice to the contrary.

                  (b)      Warrant Agent. The Company may, by written notice to
the Holder, appoint an agent for the purpose of maintaining the Warrant Register
referred to in Section 6(a) above, issuing the Shares or other securities then
issuable upon the exercise of this Warrant, exchanging this Warrant, replacing
this Warrant or any or all of the foregoing. Thereafter, any such registration,
issuance, exchange or replacement, as the case may be, shall be made at the
office of such agent.

                  (c)      Transferability and Non-negotiability of Warrant.
Subject to the provisions of this Warrant with respect to compliance with the
Securities Act and limitations on assignments and transfers, including without
limitation compliance with the restrictions on transfer set forth in Section
6(e) hereof, title to this Warrant may be transferred by endorsement (by the
transferor and the transferee executing the assignment form (the "ASSIGNMENT
FORM") attached hereto as EXHIBIT B) and delivery in the same manner as a
negotiable instrument transferable by endorsement and delivery.

                  (d)      Exchange of Warrant Upon a Transfer. On surrender of
this Warrant for exchange and a properly endorsed Assignment Form, and subject
to the provisions of this Warrant with respect to compliance with the Securities
Act and limitations on assignments and transfers, the Company shall issue to or
on the order of the Holder a new warrant or warrants with the same terms and
conditions, in the name of the Holder or as the Holder (on payment by the Holder
of any applicable transfer taxes) may direct, for the number of shares issuable
upon exercise thereof and the Company shall promptly register any such transfer
upon the Warrant Register.

                  (e)      Restrictions on Transfer of Warrants and Shares;
Compliance with Securities Laws.

                           (i)      The Holder agrees not to make any
disposition of all or any portion of the Shares or this Warrant unless and
until, and it shall be a condition to the transfer of all or any portion of the
Shares or this Warrant that: (1) there is then in effect a registration
statement under the Securities Act covering such proposed disposition and such
disposition is made in accordance with such registration statement or (2) (A)
the Holder shall have notified the Company of the proposed disposition and shall
have furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, (B) the transferee shall have agreed in
writing to be bound by the terms and conditions of this Warrant to the same
extent as if such transferee were the original Holder hereunder, (C) the
transferee shall have confirmed to the satisfaction of the Company in writing,
substantially in the form attached hereto as EXHIBIT A-1, that the Shares or the
Warrant purchased are being acquired solely for the transferee's own account and
not as a nominee for any other party, for investment and not with a view toward
distribution or resale and that the transferee shall have confirmed such other
matters related thereto as may be reasonably requested by the Company, and (D)
if requested by the Company, the Holder shall have furnished the Company with an
opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of the Warrant or such Shares under
the Securities Act; provided, however, that no registration or opinion of
counsel shall be required, with respect to a transfer by a Holder which is: (i)
a partnership, to an affiliate of such partnership; or a corporation, to a
wholly owned subsidiary of such corporation or in a distribution to its

                                       5

<PAGE>

stockholders; (ii) a partnership or affiliated partnership, to a partner of such
partnership or a retired partner of such partnership who retires after the date
hereof, or to the estate of any such partner or retired partner; or (iii) a
limited liability company, to a member of such limited liability company or a
retired member who resigns after the date hereof or to the estate of any such
member or retired member; provided further that the transferee in each case
agrees in writing to be bound by and subject to the terms, conditions,
restrictions, obligations and other limitations set forth in this Warrant to the
same extent as if it were an original party hereunder (each a "PERMITTED
TRANSFER"). This Warrant or any portion hereof and any Shares issuable pursuant
to the exercise of this Warrant that are transferred to a transferee shall be
subject to the terms, conditions, restrictions, obligations and other
limitations set forth herein.

                           (ii)     Unless exercised pursuant to an effective
registration statement under the Securities Act that includes the Shares with
respect to which the Warrant was exercised, it shall be a condition to any
exercise of this Warrant that the Holder shall have confirmed to the
satisfaction of the Company in writing, substantially in the form attached
hereto as EXHIBIT A-1, that the Shares so purchased are being acquired solely
for the Holder's own account and not as a nominee for any other party, for
investment and not with a view toward distribution or resale and that the Holder
shall have confirmed such other matters related thereto as may be reasonably
requested by the Company.

                           (iii)    This Warrant and all Shares issued upon
exercise hereof shall be stamped or imprinted with a legend in substantially the
following form (in addition to any legend required by state securities laws):

         THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED SOLELY FOR
         INVESTMENT AND NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH,
         ANY DISTRIBUTION THEREOF. SUCH SECURITIES AND THE SECURITIES ISSUED
         HEREUNDER AND THEREUNDER HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
         ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS AND
         MAY NOT BE SOLD, OFFERED, PLEDGED, HYPOTHECATED OR OTHERWISE
         TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF
         COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT
         SUCH DISPOSITION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
         DELIVERY REQUIREMENTS OF THE ACT AND ANY APPLICABLE STATE SECURITIES
         LAWS. THE WARRANT AGREEMENT OR ANY CERTIFICATE FOR SUCH SECURITIES MUST
         BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A CONDITION
         PRECEDENT TO THE SALE, PLEDGE, HYPOTHECATION OR ANY OTHER TRANSFER OF
         ANY INTEREST IN ANY OF THE SECURITIES REPRESENTED HEREBY OR THEREBY.

                           (iv)     The Holder of this Warrant, by acceptance
hereof, hereby agrees not to sell or otherwise transfer or dispose of any Shares
or other securities of the Company held by such person for a period of one
hundred eighty (180) calendar days following the effective date of a
registration statement, provided, that (a) such agreement shall only apply to
the Qualified Initial Public Offering of the Company (as defined in the
Company's Amended and Restated Investor Rights Agreement, as amended), and (b)
all stockholders of the Company then holding at least 1% of the outstanding
Common Stock (on an as converted basis) and all officers and directors of the
Company enter or have entered into similar agreements. The Holder of this
Warrant agrees to execute a market standoff agreement with the managing
underwriter of an underwritten public offering by the Company of Common Stock in
customary form consistent with the provisions of this section, provided, that
all stockholders of the Company holding at least 1% of the outstanding Common
Stock (on an as converted basis) and all officers and directors of the Company
enter or have entered into similar agreements.

                                       6

<PAGE>

                  (f)      This Warrant may not be transferred in part unless
such transfer is to a transferee, who pursuant to such transfer, receives the
right to purchase at least five thousand (5,000) Shares hereunder (as adjusted
from time to time in accordance with Section 8 hereof).

         7.       Reservation of Stock. The Company covenants that during the
term this Warrant is exercisable, the Company shall have reserved from its
authorized and unissued Common Stock a sufficient number of shares to provide
for the issuance of the Shares upon the exercise of this Warrant and, from time
to time, will take all steps necessary to amend its Certificate of Incorporation
to provide sufficient reserves of shares of Common issuable upon exercise of the
Warrant. The Company agrees that its issuance of this Warrant shall constitute
full authority of its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Shares upon
the exercise of this Warrant.

         8.       Adjustment Rights.

         The number and kind of shares purchasable hereunder and the Exercise
Price therefor are subject to adjustment from time to time, as follows:

                  (a)      Merger. If at any time there shall be any
reorganization, recapitalization, merger or consolidation involving the Company
in which shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein) are converted into or exchanged for securities, cash or other property,
other than as would cause the expiration of this Warrant under Section 10
hereof, then, as a part of such reorganization, recapitalization, merger or
consolidation, lawful provision shall be made so that the Holder shall
thereafter be entitled to receive upon exercise of its rights to purchase the
Shares hereunder, the kind and amount of securities, cash or other property of
the successor corporation resulting from such reorganization, recapitalization,
merger or consolidation, equivalent in value to that which a holder of the
Common Stock deliverable upon exercise of the right to purchase the Shares
hereunder would have been entitled in such reorganization, recapitalization,
merger or consolidation if the right to purchase the Shares hereunder had been
exercised immediately prior to such reorganization, recapitalization, merger or
consolidation. In any such case, appropriate adjustment (as determined in good
faith by the Company's Board of Directors) shall be made in the application of
the provisions of this Warrant with respect to the rights and interests of the
Holder after the reorganization, recapitalization, merger or consolidation to
the end that the provisions of this Warrant (including adjustments of the
Exercise Price and number of shares of Common Stock purchasable pursuant to the
terms and conditions of this Warrant) shall be applicable after the event, as
near as reasonably may be, in relation to any shares or other securities
deliverable after that event upon the exercise of the Holder's rights to
purchase the Shares pursuant to this Warrant.

                  (b)      Reclassification of Shares. If the Company at any
time shall, by combination, reclassification, exchange, capital reorganization
or subdivision of securities or otherwise (other than a combination,
reclassification, exchange or subdivision of shares or merger, reorganization or
other transaction otherwise provided for herein), change any of the securities
as to which purchase rights under this Warrant exist into the same or a
different number of securities of any other class or classes, this Warrant shall
thereafter represent the right to acquire such number and kind of securities as
would have been issuable as the result of such change with respect to the
securities which were subject to the purchase rights under this Warrant
immediately prior to such combination, reclassification, exchange, capital
reorganization, subdivision or other change. In any such case, appropriate
adjustment (as determined in good faith by the Company's Board of Directors)
shall be made in the application of the provisions of this Warrant with respect
to the rights and interests of the Holder after the combination,
reclassification, capital reorganization, exchange, subdivision or change to the
end that the provisions of this Warrant (including adjustments of the Exercise
Price and number of shares of Common Stock purchasable pursuant to the terms and
conditions of

                                       7

<PAGE>

this Warrant) shall be applicable after the event, as near as reasonably may be,
in relation to any shares or other securities deliverable after that event upon
the exercise of the Holder's rights to purchase the Shares pursuant to this
Warrant.

                  (c)      Subdivisions and Combinations. In the event that the
Company shall at any time subdivide (by stock split, by payment of a stock
dividend or otherwise) the outstanding shares of Common Stock, or shall issue a
stock dividend on its outstanding shares of Common Stock, the number of Shares
issuable upon exercise of this Warrant immediately prior to such subdivision
shall, concurrently with the effectiveness of such subdivision, be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine (by
reclassification or otherwise) the outstanding shares of Common Stock into a
lesser number of shares of Common Stock, the number of Shares issuable upon
exercise of this Warrant immediately prior to such combination shall,
concurrently with the effectiveness of such combination, be proportionately
decreased, and the Exercise Price shall be proportionately increased.

                  (d)      Notice of Adjustments. Upon any adjustment of the
Exercise Price or any increase or decrease in the number of Shares purchasable
upon the exercise of this Warrant in accordance with this Section 8, then, and
in each such case, the Company, within ten (10) days thereafter, shall give
written notice thereof, in the form of a certificate of the chief financial
officer, principal accounting officer, treasurer or controller of the Company,
to the Holder at the address of such Holder as shown on the Warrant Register of
the Company, delivered by any method provided in Section 11(d) hereof, which
notice shall state the event giving rise to the adjustment, the Exercise Price
as adjusted and, if applicable, the increased or decreased number of Shares
purchasable upon the exercise of this Warrant, setting forth in reasonable
detail the method of calculation of each.

                  (e)      Other Notices. In the event that the Company shall
authorize: (1) the issuance of any dividend or other distribution on the Common
Stock (other than: (i) repurchases of Common Stock issued to or held by
employees, officers, directors or consultants of the Company or its subsidiaries
upon termination of their employment or services pursuant to agreements
providing for the right of said repurchase; (ii) repurchases of Common Stock
issued to or held by employees, officers, directors or consultants of the
Company or its subsidiaries pursuant to rights of first refusal contained in
agreements providing for such right; or (iii) repurchases of capital stock of
the Company in connection with the settlement of disputes with any stockholder),
whether in cash, property, stock or other securities; (2) the voluntary or
involuntary liquidation, dissolution or winding up of the Company; or (3) any
transaction resulting in the expiration of this Warrant pursuant to Section 10
hereof; then, in each such case, the Company shall give written notice thereof
to the Holder at the address of such Holder as shown on the Warrant Register of
the Company, delivered by any method provided in Section 11(d) hereof, at least
ten (10) days prior to the effective date of such event. The notice provisions
set forth in this section may be shortened or waived prospectively or
retrospectively by the vote or written consent of the holders of a majority of
the Shares issuable upon exercise of the Warrant.

         9.       No Rights As Stockholders. Nothing contained herein shall
entitle the Holder to any rights as a Stockholder of the Company or to be deemed
the holder of Common Stock or any other securities of the Company that may at
any time be issuable on the exercise hereof for any purpose nor shall anything
contained herein be construed to confer upon the Holder, as such, any right to
vote for the election of directors or upon any matter submitted to Stockholders
at any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value or change of stock to no par value, consolidation,
merger, conveyance or otherwise) or to receive notice of meetings, or to receive
dividends or subscription rights or otherwise or any other rights of a

                                       8

<PAGE>

Stockholder of the Company until the Warrant shall have been exercised and the
Shares purchasable upon exercise hereof shall have become deliverable as
provided herein.

         10.      Expiration of Warrant. This Warrant shall expire and shall no
longer be exercisable as of the earlier of:

                  (a)      5:00 p.m., Pacific standard time, on March 13, 2007;

                  (b)      (i) the acquisition of the Company by another entity
by means of any transaction or series of related transactions (including,
without limitation, any stock acquisition, reorganization, merger or
consolidation) other than a transaction or series of transactions in which the
holders of the voting securities of the Company outstanding immediately prior to
such transaction continue to retain (either by such voting securities remaining

                       INVESTMENT REPRESENTATION STATEMENT

HOLDER:           _________________________________

COMPANY:          NETGEAR, INC.

SECURITIES:       THE WARRANT (THE "WARRANT") TO PURCHASE SHARES OF COMMON STOCK
                  ISSUED ON MARCH 13, 2002 AND THE COMMON STOCK ISSUED OR
                  ISSUABLE UPON EXERCISE THEREOF

AMOUNT:           __________________________ SHARES

DATE:             __________________, ______

         In connection with the purchase of the above-listed Securities, the
undersigned Holder represents and warrants to, and agrees with, the Company as
follows:

         1.       No Registration. The Holder understands that the Securities
have not been, and will not be, registered under the Securities Act of 1933, as
amended (the "SECURITIES ACT"), by reason of a specific exemption from the
registration provisions of the Securities Act, the availability of which depends
upon, among other things, the bona fide nature of the investment intent and the
accuracy of the Holder's representations as expressed herein or otherwise made
pursuant hereto.

         2.       Investment Intent. The Holder is acquiring the Securities for
investment for its own account, not as a nominee or agent, and not with the view
to, or for resale in connection with, any distribution thereof.

         3.       Investment Experience. The Holder has substantial experience
in evaluating and investing in private placement transactions of securities in
companies similar to the Company so that it is capable of evaluating the merits
and risks of its investment in the Company and has the capacity to protect its
own interests.

         4.       Speculative Nature of Investment. The Holder acknowledges that
its investment in the Company is highly speculative and entails a substantial
degree of risk and the Holder is in a position to lose the entire amount of such
investment.

         5.       Access to Data. The Holder has had an opportunity to discuss
the Company's business, management and financial affairs with the Company's
management. The Holder has also had an opportunity to ask questions of officers
of the Company, which questions were answered to its satisfaction. The Holder
understands that such discussions, as well as any information issued by the
Company, were intended to describe certain aspects of the Company's business and
prospects, but were not necessarily a thorough or exhaustive description. The
Holder acknowledges that any business plans prepared by the Company have been,
and continue to be, subject to change and that any projections included in such
business plans or otherwise are necessarily speculative in nature, and it can be
expected that some or all of the assumptions underlying the projections will not
materialize or will vary significantly from actual results.

                                     A-1-1

<PAGE>

         6.       Accredited Investor. The Holder is an "accredited investor"
within the meaning of Regulation D, Rule 501(a), promulgated by the Securities
and Exchange Commission.

         7.       Residency. The residency of the Holder (or, in the case of a
partnership or corporation, such entity's principal place of business) is
correctly set forth on the signature page hereto.

         8.       Restriction on Resales. The Holder acknowledges that the
Securities must be held indefinitely unless subsequently registered under the
Securities Act or unless an exemption from such registration is available. The
Company has no present intention of registering the Securities. The Holder
further understands that there is no assurance that any exemption from
registration under the Securities Act will be available or, if available, that
such exemption will allow the Holder to dispose of or otherwise transfer any or
all of the Securities under the circumstances, in the amounts or at the times
the Holder might propose.

         9.       Authorization.

                  (a)      The Holder has all requisite power and authority to
execute and deliver the Warrant, to purchase the Securities and to carry out and
perform its obligations under the terms of the Warrant. All action on the part
of the Holder necessary for the authorization, execution, delivery and
performance of the Warrant, and the performance of all of the Holder's
obligations under the Warrant, has been taken or will be taken prior to the
purchase of the Warrant.

                  (b)      The Warrant, when executed and delivered by the
Holder, will constitute a valid and legally binding obligation of the Holder,
enforceable in accordance with its terms except: (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors' rights generally, and (ii) as
limited by laws relating to the availability of specific performance, injunctive
relief or other equitable remedies or by general principles of equity.

                  (c)      No consent, approval, authorization, order, filing,
registration or qualification of or with any court, governmental authority or
third person is required to be obtained by the Holder in connection with the
execution and delivery of the Warrant or the performance of the Holder's
obligations hereunder.

         10.      Brokers or Finders. The Holder has not engaged any brokers,
finders or agents, and the Company has not incurred and will not incur, directly
or indirectly, as a result of any action taken by the Holder, any liability for
brokerage or finders' fees or agents' commissions or any similar charges in
connection with the Warrant.

         11.      Investor Counsel. The Holder acknowledges that it has had the
opportunity to review the Warrant, the exhibits and schedules attached thereto
and the transactions contemplated by the Warrant with its own legal counsel. The
Holder is relying solely on such counsel and not on any statements or
representations of the Company or its agents for legal advice with respect to
this investment or the transactions contemplated by the Warrant.

         12.      Tax Advisors. The Holder has reviewed with its own tax
advisors the U.S. federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by the Warrant. With respect to
such matters, the Holder relies solely on such advisors and not on any
statements or representations of the Company or any of its agents, written or
oral. The Holder understands that it (and not the Company) shall be responsible
for its own tax liability that may arise as a result of this investment or the
transactions contemplated by the Warrant.

                                     A-1-2

<PAGE>

         13.      Further Limitations on Disposition. Without in any way
limiting the representations and warranties set forth above, the Holder agrees
not to make any disposition of all or any portion of the Securities unless and
until, and it shall be a condition to the transfer of all or any portion of the
Securities that: (1) there is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement or (2) (A) the Holder shall have
notified the Company of the proposed disposition and shall have furnished the
Company with a detailed statement of the circumstances surrounding the proposed
disposition, (B) the transferee shall have agreed in writing to be bound by the
terms and conditions of the Warrant to the same extent as if such transferee
were the original Holder thereunder, (C) the transferee shall have confirmed to
the satisfaction of the Company in writing, substantially in the form attached
to the Warrant as EXHIBIT A-1, that the Securities are being acquired solely for
the transferee's own account and not as a nominee for any other party, for
investment and not with a view toward distribution or resale and that the
transferee shall have confirmed such other matters related thereto as may be
reasonably requested by the Company, and (D) if requested by the Company, the
Holder shall have furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of the Securities under the Securities Act; provided, however, that no
registration or opinion of counsel shall be required, with respect to a transfer
by a Holder which is: (i) a partnership, to an affiliate of such partnership; or
a corporation, to a wholly owned subsidiary of such corporation or in a
distribution to its stockholders; (ii) a partnership or affiliated partnership,
to a partner of such partnership or a retired partner of such partnership who
retires after the date hereof, or to the estate of any such partner or retired
partner; or (iii) a limited liability company, to a member of such limited
liability company or a retired member who resigns after the date hereof or to
the estate of any such member or retired member; provided further that the
transferee in each case agrees in writing to be bound by and subject to the
terms, conditions, restrictions, obligations and other limitations set forth in
the Warrant to the same extent as if it were an original party thereunder (each
a "PERMITTED TRANSFER"). The Securities that are transferred to a transferee
shall be subject to the terms, conditions, restrictions, obligations and other
limitations set forth herein and therein.

         14.      Market Standoff. The Holder agrees not to sell or otherwise
transfer or dispose of any Securities held by such person for a period of one
hundred eighty (180) calendar days following the effective date of a
registration statement, provided, that (a) such agreement shall only apply to
the Qualified Initial Public Offering of the Company (as defined in the
Company's Amended and Restated Investor Rights Agreement, as amended), and (b)
all stockholders of the Company then holding at least 1% of the outstanding
Common Stock (on an as converted basis) and all officers and directors of the
Company enter or have entered into similar agreements. The Holder agrees to
execute a market standoff agreement with the managing underwriter of an
underwritten public offering by the Company of Common Stock in customary form
consistent with the provisions of this section, provided, that all stockholders
of the Company holding at least 1% of the outstanding Common Stock (on an as
converted basis) and all officers and directors of the Company enter or have
entered into similar agreements.
