     3.   Required Registration.
          ---------------------

          (a)  If and whenever the Company shall receive a written request
therefor from the Initiating Holder, the Company agrees to prepare and file
promptly, and in any event within 45 days after such request, a registration
statement under the Securities Act covering the shares of Registrable Securities
which are the subject of such request and agrees to use its best efforts to

                                       5
<PAGE>

cause such registration statement to become effective. Upon the receipt of such
request, the Company agrees to give prompt written notice to all Holders of
Registrable Securities that such registration is to be initiated. The Company
agrees to include in such registration statement such shares of Registrable
Securities for which it has received written requests to register such shares by
the Holders thereof within thirty (30) days after the receipt of written notice
from the Company.

          (b)  The Company shall not be required to effect a registration
requested pursuant to this Section 3:

               (i)   if within thirty (30) days of receipt of a written request
from the Initiating Holder pursuant to Section 3(a), the Company gives notice to
the Holders of the Company's intention to commence a Public Offering of Class A
Shares to be originally issued by the Company within sixty (60) days, so long as
(v) a registration statement with respect thereto is filed with the Commission
within forty-five (45) days thereafter and (w) thereafter the Company uses its
best efforts to cause such registration statement to be declared effective;
provided, however, that the Company shall not exercise this right a second time
if (x) the Company fails to file a registration statement within the period
specified or (y) Holders have requested to initiate a registration pursuant to
this Section 3 which either has not been declared effective or has not been
withdrawn by such Holders; or

               (ii)  if the Company shall furnish to Holders requesting
registration pursuant to this Section 3, a certificate signed by the Chairman of
the Board stating that in the good faith judgment of the Board of Directors of
the Company, it would be seriously detrimental to the Company and its
stockholders for such registration statement to be effected at such time, in
which event the Company shall have the right to defer such filing for a period
of not more than ninety (90) days after receipt of the request of the Initiating
Holder; provided that such right to delay a registration shall be exercised by
the Company not more than once in any twelve (12) month period; or

               (iii) in the case of any requested registration the estimated
aggregate gross proceeds to the selling security holders would be less than
$5,000,000.

          (c)  Notwithstanding anything to the contrary contained herein, the
Initiating Holder (including for this purpose all transferees and assignees
thereof as permitted by this Agreement) shall only have the right to initiate
one registration pursuant to this Section 3, provided that, at the time of such
request, such Initiating Holder owns Shares equal to at least fifty percent
(50%) of such Initiating Holder's Original Issued Amount.

          (d)  (i)  The Company shall not be required by this Section 3 to
effect a registration of Registrable Securities pursuant to any registration
statement of Form F-3 unless the proposed public offering price of the
securities to be included in such registration shall be at least $1,500,000.

               (ii) The Company shall not be required to register the
Registrable Securities of a Holder in the event that the Company determines that
all of the Registrable Securities proposed by such Holder to be registered could
be sold by such Holder in a single

                                       6
<PAGE>

transaction pursuant to Rule 144 and the Company agrees to remove the legend
referred to in Section 2(d)(A).

          (e)  Any registration under this Section 3 shall be on the least
burdensome of Forms F-1, F-2 or F-3 (or any successor forms) for which the
Company in the proposed transaction is then eligible. The Company will notify
the Holders at such time as the Company qualifies to register Registrable
Securities on Form F-3, and thereafter and so long as it qualifies for such Form
F-3, the Company will effect any such registration properly requested pursuant
to this Section 3, on Form F-3, unless agreed to the contrary with the
Initiating Holder. An F-3 registration requested by the Holders shall be deemed
to have been made pursuant to the proviso in Section 3(c), but shall be subject
to the restrictions set forth in Section 3(d)(i).

          (f)  If the Holders initiating a request for the registration of
Registrable Securities pursuant to this Section 3 intend to distribute the
Registrable Securities covered by their request by means of a Public Offering,
the right of any Holder to registration pursuant to this Section 3 shall be
conditioned upon such Holder's participation in such Public Offering and the
inclusion of such Holder's Registrable Securities in the Public Offering to the
extent requested (unless otherwise mutually agreed by the Holders of a Majority
of the Registrable Securities initiating such request for registration and such
Holder) to the extent provided herein. All Holders proposing to distribute their
securities through such Public Offering agree to enter into (together with the
Company) an underwriting agreement with the underwriter or underwriters selected
for such underwriting which shall be in customary form and on terms and
conditions reasonably acceptable to the Company and those Holders of the
Registrable Securities participating in such registration. If any Holder of
Registrable Securities does not agree to enter into an underwriting agreement
having such terms and conditions, such Holder shall withdraw the Registrable
Securities proposed to be registered by it from the registration and shall
reimburse the Company for the incremental amount of registration expenses
incurred by the Company in connection with the registration of the Registrable
Securities such Holder was proposing to sell within thirty (30) days after such
withdrawal. Such underwriters shall be selected by the Company (i) among the
list of nationally recognized investment banking firms attached to this
Agreement as Annex B, or (ii) approved by the Holders of the Registrable
Securities participating in such registration, such approval not to be
unreasonably withheld or delayed..

          (g)  Notwithstanding any other provision of this Section 3, if the
managing underwriter of a Public Offering advises the Company and the Holders of
Registrable Securities participating in such registration in writing that in its
good faith judgment the number of shares of Registrable Securities requested to
be included in such registration exceeds the number of shares of Registrable
Securities which can be sold in such offering without having a material and
adverse effect upon the success of such offering, including the price at which
such Registrable Securities can be sold, then (i) the number of shares of
Registrable Securities so requested to be included in such registration shall be
reduced to that number of shares which in the good faith judgment of the
managing underwriter can be sold in such offering and (ii) this reduction in the
aggregate number of shares to be registered shall be allocated among all Holders
thereof first, by reducing the number of shares pursuant to the exercise of any
        -----
incidental registration rights granted to Persons other than the Holders; and
second, by reducing the number of shares to be registered by the Holders
------
exercising or participating in a demand registration initiated pursuant

                                       7
<PAGE>

to Section 3(a). If the number of Registrable Securities to be registered by a
Holder pursuant to Section 3 is reduced in accordance with this Section 3(g) to
less than 75% of the number originally requested to be registered by such
Holder, then in no event shall such registration be deemed to have been a
"registration" for purposes of the limitations on the number of registrations to
which a Holder is entitled hereunder contained in Section 3(c).

          (h)  If the managing underwriter has not limited the number of
Registrable Securities to be underwritten, the Company and other holders of the
Company's securities may include securities for its (or their) own account in
such registration if the managing underwriter so agrees and if the number of
Registrable Securities which would otherwise have been included in such
registration and underwriting will not thereby be limited.

          (i)  A registration effected pursuant to this Section 3 shall not be
deemed to have been effected until the applicable registration statement shall
have become effective under the Securities Act (and not subject to any stop
order, injunction or other order or requirement of the Commission or other
governmental agency or court for any reason) for the period specified in Section
5(a). The Initiating Holder may, before any registration statement becomes
effective, withdraw its Registrable Securities from inclusion therein, should
the terms of the proposed distribution not be satisfactory to such Holder. If
Holders holding in the aggregate 50% or more of the Registrable Securities
requested to be included in such registration elect to withdraw such
registration statement, such registration statement shall be withdrawn (if
necessary) and such registration shall not be deemed to have been a
"registration" for purposes of the limitations on the number of registrations
hereunder contained in this Section 3; provided, that the Holders of Registrable
Securities shall reimburse the Company for their pro rata portion of the
registration expenses incurred by the Company in connection with such
registration within 30 days after such withdrawal (unless at the time of such
withdrawal, such withdrawing Holders of Registrable Securities have learned of a
material adverse change in the operating results, financial condition or
business of the Company of which such Holders were not aware as of the time of
the written request for a registration pursuant to this Section 3 and have
withdrawn such request promptly following the disclosure by the Company of such
material adverse change, in which case, the Holders of Registrable Securities
which were to be included in such registration shall not be obligated to
reimburse the Company for such registration expenses in order to preserve their
respective rights under this Section 3).

     4.   Incidental Registration.
          -----------------------

          (a)  Each time the Company shall determine to file a registration
statement under the Securities Act (other than (i) pursuant to Section 3 hereof,
(ii) on Form F-4 or another registration statement for shares to be issued in a
merger or acquisition transaction, or (iii) a registration statement covering
solely an employee benefit plan. Upon the written request of any such Holder
given within thirty (30) days after the receipt of such written notice from the
Company, the Company agrees to use its best efforts to cause all Registrable
Securities, held by such Holders which such Holders have so requested
registration thereof, to be included in such registration statement and
registered under the Securities Act, all to the extent required to permit the
sale or other disposition of such Registrable Securities.

                                       8
<PAGE>

          (b)  If the registration of which the Company gives written notice
pursuant to Section 4(a) is for a Public Offering, the Company agrees to so
advise each Holder as a part of its written notice. In such event the right of
any such Holder to registration pursuant to this Section 4 shall be conditioned
upon such Holder's participation in such Public Offering and the inclusion of
such Holder's Registrable Securities in the Public Offering to the extent
provided herein. All Holders distributing their Registrable Securities through
such Public Offering agree to enter into (together with the Company and the
other holders distributing their securities through such Public Offering) an
underwriting agreement with the underwriter or underwriters selected for such
underwriting by the Company, provided that such underwriting agreement is in
customary form and is reasonably acceptable to the Company and the Holder
selling Registrable Securities through such underwriting. If any Holder of
Registrable Securities does not agree to enter into an underwriting agreement
having such terms and conditions, such Holder shall withdraw from such
registration the Registrable Securities proposed to be registered by it and
shall reimburse the Company for the incremental amount of registration expenses
incurred by the Company in connection with the registration of the Registrable
Securities such Holder was proposing to sell within thirty (30) days after such
withdrawal.

          (c)  Notwithstanding any other provision of this Section 4, if the
managing underwriter of a Public Offering advises the Company and the Holders of
the Registrable Securities participating in such Public Offering in writing that
in its good faith judgment the number of shares of Registrable Securities and
the other securities to be registered exceeds the number of shares of
Registrable Securities and other securities which can be sold in such offering
without having a material and adverse effect upon the success of such offering,
including the price at which such Registrable Securities can be sold, then (i)
the number of shares of Registrable Securities and other securities so requested
to be included in the offering shall be reduced to that number of shares which
in the good faith judgment of the managing underwriter can be sold in such
offering (except for shares to be issued by the Company in an offering initiated
by and for the account of the Company, which, subject to the first proviso of
Section 3(b)(iii), shall have priority over the shares of Registrable
Securities), and (ii) such reduced number of shares shall be allocated among all
participating Holders of Registrable Securities and the holders of other
securities in proportion, is nearly as practicable, to the respective number of
shares of Registrable Securities proposed to be offered and sold in such
registration.

          (d)  Any Holder of Registrable Securities may elect to withdraw its
respective Registrable Securities from inclusion in a registration to be
effected pursuant to this Section 4 at any time prior to five (5) at any time
prior to five (5) Business Days prior to the then anticipated effective date of
the applicable registration statement.

     5.   Registration Procedures. If and whenever the Company is required by
          -----------------------
the provisions of Section 3 or 4 hereof to use its best efforts to effect the
registration of Registrable Securities under the Securities Act, the Company
agrees to:

          (a)  In accordance with the Securities Act and all applicable rules
and regulations, prepare and file with the Commission a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective until the earlier of (i)

registration statement, and prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus contained
therein as may be necessary to keep such registration statement effective and
such registration statement and prospectus accurate and complete until the
earlier of (i) such ninety (90) day period or (ii) the sale of the securities
covered by such registration statement;

          (b)  Furnish to the Holders of securities participating in such
registration and to the underwriters of the securities being registered, without
charge and as soon as such documents become available to the Company, such
number of copies of the registration statement and each amendment and supplement
thereto, preliminary prospectus, final prospectus and such other documents as
such underwriters and Holders may reasonably request in order to facilitate the
public offering of such securities;

          (c)  Use its best efforts to register or qualify the securities
covered by such registration statement under such state securities or blue sky
laws of such jurisdictions as such participating Holders and underwriters may
reasonably request within ten (10) days prior to the original filing of such
registration statement, except that the Company shall not for any purpose be
required to execute a general consent to service of process or to qualify to do
business as a foreign corporation in any jurisdiction where it is not so
qualified;

          (d)  Notify the Holders participating in such registration, promptly
after it shall receive notice thereof, of the date and time when such
registration statement and each post-effective amendment thereto has become
effective or a supplement to any prospectus forming a part of such registration
statement has been filed;

          (e)  Notify such Holders promptly of any request by the Commission for
the amending or supplementing of such registration statement or prospectus or
for additional information;

          (f)  If, at the time when a prospectus relating to such securities is
required to be delivered under the Securities Act, any event has occurred as the
result of which any such prospectus or any other prospectus as then in effect
would include an untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, notify as promptly as practicable each Holder of
Registrable Securities participating in such registration of the happening of
such event and prepare and file as promptly as practicable with the Commission,
and as promptly as practicable notify such Holders of the filing of, such
amendments or supplements to such registration statement or prospectus as may be
necessary to correct any statements or omissions.

          (g)  Advise such Holders, as promptly as practicable after it shall
receive notice or obtain knowledge thereof, of the issuance, or threatened
issuance, of any stop order or other order by the Commission suspending the
effectiveness of such registration statement; use its best efforts to prevent
the issuance of any such threatened stop order or other order of which it
becomes aware; and, if such stop order or other order is issued, promptly use
its best efforts to obtain a lifting of such order as promptly as possible and
promptly notify each such Holder of any such lifting or withdrawal.

                                       10
<PAGE>

               (h)  Make available for inspection upon request by any Holder of
     Registrable Securities covered by such registration statement, by any
     managing underwriter of any distribution to be effected pursuant to such
     registration statement and by any attorney, accountant or other agent
     retained by any such Holder or any such underwriter, all financial and
     other records, pertinent corporate documents and properties of the Company,
     and cause all of the Company's officers, directors and employees to supply
     all information reasonably requested by any such Holder, underwriter,
     attorney, accountant or agent in connection with such registration
     statement; and

               (i)  At the request of any Holder of Registrable Securities
     covered by such registration statement, furnish to such Holder on the
     effective date of the registration statement or, if such registration
     includes an underwritten public offering, at the closing provided for in
     the underwriting agreement, (i) an opinion dated such date of the counsel
     representing the Company for the purposes of such registration, addressed
     to the underwriters, if any, and to the Holder or Holders making such
     request (which opinion shall be reasonably acceptable to such Holders), and
     (ii) a copy of the "cold comfort" letter executed by the Company's
     independent certified public accountants and delivered by such accountants
     to the underwriters, each covering such matters as are customarily the
     subject of opinions of issuer's counsel or independent certified public
     accountants, as the case may be, provided to underwriters in Public
     Offerings.

          6.   Expenses.
               --------

               (a)  With respect to each registration effected pursuant to
     Section 3 hereof and with respect to each inclusion of shares of
     Registrable Securities in a registration statement pursuant to Section 4
     hereof, the Company agrees to bear all fees, costs and expenses of and
     incidental to the Company's performance of or compliance with this
     Agreement (the "Registration Expenses"); provided, however, that the
     Holders participating in any such registration shall bear, on a pro rata
     basis, all underwriting discounts and commissions attributable to
     Registrable Securities sold pursuant to such registration statement by such
     Holders. Such fees, costs and expenses to be borne by the Company shall
     include, without limitation, all registration, filing and NASD fees,
     printing expenses, fees and disbursements of counsel and accountants for
     the Company, all legal fees and disbursements and other expenses of
     complying with state securities or blue sky laws of any jurisdictions in
     which the securities to be offered are to be registered or qualified,
     reasonable fees and disbursements of one firm of counsel for the selling
     Holders, up to $25,000 per registered offering, selected by the Holders of
     a majority of the shares of Registrable Securities to be included in such
     registration, and the premiums and other costs of policies of insurance
     against liability arising out of such offering. Notwithstanding anything to
     the contrary contained herein, the Company shall not be required to pay for
     expenses of any registration of securities begun pursuant to Section 3, the
     request for which has been subsequently withdrawn by the Initiating Holder
     unless (i) the withdrawal is based upon material adverse information
     concerning the Company of which the Initiating Holder was not aware at the
     time of making such request, (ii) such Initiating Holder agrees to forfeit
     its right to request a registration pursuant to Section 3(c), in which
     event such right shall be forfeited by such Holder (provided, that such
     forfeiture will not affect its rights under the proviso set forth in the
     last sentence of Section 3(c)). If the Company is required to pay the
     Registration Expenses of a withdrawn offering pursuant to clause (i) of the
     preceding sentence, then the

                                       11
<PAGE>

     Holder initiating the request for such registration shall not forfeit its
     rights pursuant to Section 3 to a demand registration.

               (b)  To the extent Registration Expenses are not required to be
     paid by the Company, such Registration Expenses shall be borne by the
     Holders of securities (including Registrable Securities) requesting such
     registration in proportion to the number of shares owned by each such
     requesting Holder which are included in any registration effected pursuant
     to Section 3 or Section 4.

          7.   Indemnification.
               ---------------

               (a)  The Company hereby agrees to indemnify and hold harmless, to
     the full extent permitted by law, each Holder of Registrable Securities,
     which are included in a registration statement pursuant to the provisions
     of this Agreement and each of such Holder's officers, directors, employees,
     attorneys, accountants and agents, and each Person who controls such Holder
     within the meaning of the Securities Act from and against, and agrees to
     reimburse such Holder, its officers, directors, employees, attorneys,
     accountants and agents, and controlling Persons with respect to, any and
     all claims, actions, demands, losses, damages, liabilities, costs and
     expenses to which such Holder, its officers, directors, employees,
     attorneys, accountants and agents, or controlling Persons, may become
     subject under applicable laws, insofar as such claims, actions, demands,
     losses, damages, liabilities, costs or expenses arise out of or are based
     upon any untrue statement or alleged untrue statement of any material fact
     contained in such registration statement, any prospectus contained therein,
     or any amendment or supplement thereto, or arise out of or are based upon
     the omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading; provided, however, that the Company will not be liable in any
     such case to the extent that any such claim, action, demand, loss, damage,
     liability, cost or expense is caused by an untrue statement or alleged
     untrue statement or omission or alleged omission so made in strict
     conformity with written information furnished by such Holder, such
     underwriter or such controlling Person specifically for use in the
     preparation thereof.

               (b)  Each Holder of shares of Registrable Securities which are
     included in a registration statement pursuant to the provisions of this
     Agreement hereby agrees, severally and not jointly, to indemnify and hold
     harmless, to the full extent permitted by law, the Company, its officers,
     directors, employees, attorneys, accountants and agents, and each Person
     who controls the Company within the meaning of the Securities Act, from and
     against, and agrees to reimburse the Company, its officers, directors,
     employees, attorneys, accountants and agents, and controlling Persons with
     respect to, any and all claims, actions, demands, losses, damages,
     liabilities, costs or expenses to which the Company, its officers,
     directors or such controlling Persons may become subject under applicable
     laws, insofar as such claims, actions, demands, losses, damages,
     liabilities, costs or expenses are caused by any untrue or alleged untrue
     statement of any material fact contained in such registration statement,
     any prospectus contained therein or any amendment or supplement thereto, or
     are caused by the omission or the alleged omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein, in light of the circumstances in which they were made,
     not misleading, in each case to the extent, but only to the extent, that
     such untrue statement or alleged untrue statement or omission or alleged
     omission was so made in strict conformity with written

                                       12
<PAGE>

     information furnished by such Holder specifically for use in the
     preparation thereof. Notwithstanding the foregoing, no Holder of
     Registrable Securities shall be obligated hereunder to pay more than the
     net proceeds realized by it upon its sale of Registrable Securities
     included in such registration statement.

               (c)  Promptly after receipt by a party entitled to
     indemnification pursuant to the provisions of subsection (a) or (b) of this
     Section 7 of notice of the commencement of any action involving the subject
     matter of the foregoing indemnity provisions, such indemnified party will,
     if a claim therefor is to be made against the indemnifying party pursuant
     to the provisions of subsection (a) or (b), notify the indemnifying party
     of the commencement thereof; but the omission so to notify the indemnifying
     party will not relieve it from any liability which it may have to an
     indemnified party otherwise than under this Section 7 and shall not relieve
     the indemnifying party from liability under this Section 7 unless such
     indemnifying party is materially prejudiced by such omission. In case any
     such action is brought against any indemnified party, and it notifies the
     indemnifying party of the commencement thereof, the indemnifying party will
     be entitled to participate therein and, to the extent that it may wish,
     jointly with any other indemnifying parties similarly notified, to assume
     the defense thereof, with counsel reasonably satisfactory to such
     indemnified party; provided, however, that if the defendants in any such
     action include both the indemnified party and the indemnifying party and
     the indemnified party shall have reasonably concluded that there may be
     legal defenses available to it and/or other indemnified parties which are
     different from or additional to those available to the indemnifying party,
     the indemnified party or parties shall have the right to select separate
     counsel (in which case the indemnifying party shall not have the right to
     direct the defense of such action on behalf of the indemnified party or
     parties). Upon the permitted assumption by the indemnifying party of the
     defense of such action, and approval by the indemnified party of counsel,
     the indemnifying party shall not be liable to such indemnified party under
     subsection (a) or (b) for any legal or other expenses subsequently incurred
     by such indemnified party in connection with the defense thereof (other
     than reasonable costs of investigation) unless (i) the indemnified party
     shall have employed separate counsel in connection with the assertion of
     legal defenses in accordance with the proviso to the immediately preceding
     sentence, or (ii) the indemnifying party and its counsel do not actively
     pursue the defense of such action. No indemnifying party shall be liable to
     an indemnified party for any settlement of any action or claim without the
     consent of the indemnifying party and no indemnifying party may
     unreasonably withhold its consent to any such settlement. No indemnifying
     party will 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 with respect to such claim or litigation.

               (d)  If the indemnification provided for in subsection (a) or (b)
     of this Section 7 is held by a court of competent jurisdiction to be
     unavailable to a party to be indemnified with respect to any claims,
     actions, demands, losses, damages, liabilities, costs or expenses referred
     to therein, then each indemnifying party under any such subsection, in lieu
     of indemnifying such indemnified party thereunder, hereby agrees to
     contribute to the amount paid or payable by such indemnified party as a
     result of such claims, actions, demands, losses, damages, liabilities,
     costs or expenses in such proportion as is appropriate to reflect the
     relative fault of the indemnifying party on the one hand and of the
     indemnified party on the other in connection with the statements or
     omissions which resulted in such claims, actions, demands,

                                       13
<PAGE>

     losses, damages, liabilities, costs or expenses, as well as any other
     relevant equitable considerations. The relative fault of the indemnifying
     party and of the indemnified party shall be determined by reference to,
     among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission or alleged omission to state a material fact
     relates to information supplied by the indemnifying party or by the
     indemnified party and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission. Notwithstanding the foregoing, no Holder of Registrable
     Securities shall be obligated hereunder to contribute more than the net
     proceeds realized by it upon its sale of Registrable Securities included in
     such registration statement.

               No person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Securities Act) shall be entitled to
     contribution hereunder from any person who was not guilty of such
     fraudulent misrepresentation.

               (e)  The Company and the Holders of Registrable Securities agree
     that customary indemnification arrangements relating to any underwriter (as
     defined in the Securities Act) involved in the Public Offering and any
     controlling Person of such underwriter shall be set forth in the
     underwriting agreement executed by the Company and such Holder in
     connection with the registration of Registrable Securities in accordance
     herewith.

          8.   Rule 144 Reporting. With a view to making available to the
               ------------------
     Investors the benefits of certain rules and regulations of the Commission
     which may permit the sale of the Registrable Securities to the public
     without registration, the Company agrees to use its best efforts to:

               (a)  Make and keep public information available, as those terms
     are understood and defined in Rule 144 at all times;

               (b)  File with the Commission, in a timely manner, all reports
     and other documents required of the Company under the Exchange Act; and

               (c)  So long as an Investor owns any Registrable Securities,
     furnish to such Holder forthwith upon request: a written statement by the
     Company as to its compliance with the reporting requirements of Rule 144,
     and of the Exchange Act (at any time after it has become subject to such
     reporting requirements); a copy of the most recent annual or quarterly
     report of the Company; and such other reports and documents as a Holder may
     reasonably request in availing itself of any rule or regulation of the
     Commission allowing it to sell any such securities without registration.

          9.   [Intentionally Left Blank]
               --------------------------


          10.  Stockholder Information.  The Company may request each Holder of
               -----------------------
     Registrable Securities as to which any registration is to be effected
     pursuant to this Agreement to furnish the Company with such information
     with respect to such Holder and the distribution of such Registrable
     Securities as the Company may from time to time reasonably request in
     writing and as shall be required by law or by any securities commission
     (including the Commission), stock exchange or self-regulatory agency in
     connection therewith, and each Holder of Registrable

                                       14
<PAGE>

     Securities as to which any registration is to be effected pursuant to this
     Agreement agrees to furnish the Company with such information.

          11.  Forms.  All references in this Agreement to particular forms of
               -----
     registration statements are intended to include, and shall be deemed to
     include, references to all successor forms which are intended to replace,
     or to apply to similar transactions as, the forms herein referenced and to
     references to all forms available to a foreign registrant where any
     referenced form of registration statement is only available to a domestic
     registrant or vice versa.

          12.  Miscellaneous.
               -------------

               (a)  Waivers and Amendments. Except as otherwise expressly
                    ----------------------
    provided, in this Agreement may be amended or modified only upon the written
    consent of the Company and each Investor for so long as it has any rights or
    obligations hereunder. Except as otherwise expressly provided in this
    Agreement, the rights of an Investor under this Agreement may be waived only
    with the written consent of such Investor. Except as otherwise provided in
    this Agreement, the rights of the Company under this Agreement may be waived
    only with the written consent of the Company. Neither this Agreement nor any
    provision hereof may be changed, waived, discharged or terminated orally or
    by course of dealing, but only by a statement in writing signed by the party
    against which enforcement of the change, waiver, discharge or termination is
    sought, except to the extent provided in this Section 12(a). Specifically,
    but without limiting the generality of the foregoing, the failure of any
    party at any time or times to require performance of any provision hereof by
    another party shall in no manner affect the right of such first party at a
    later time to enforce the same. No waiver by any party of the breach of any
    term or provision contained in this Agreement, in any one or more instances,
    shall be deemed to be, or construed as, a further or continuing waiver of
    any such breach, or a waiver of the breach of any other term or covenant
    contained in this Agreement.

               (b)  Notices. All notices required or permitted hereunder shall
                    -------
     be in writing and shall be deemed effectively given: (i) upon personal
     delivery to the party to be notified; (ii) when sent by confirmed telex or
     facsimile if sent during normal business hours of the recipient, if not,
     then on the next business day; (iii) three (3) days after having been sent
     by registered or certified mail, return receipt requested, postage prepaid;
     or (iv) one (1) day after deposit with a nationally recognized overnight
     courier, specifying next day delivery, with written verification of
     receipt. All communications shall be sent to the Company at 401 East
     Middlefield Road, Mountain View, California 94043, and to each Investor at
     its address set forth on Annex A attached hereto or at such other address
     as the Company or Investor may designate by ten (10) days advance written
     notice to the other parties hereto.

               (c)  Severability. In the event of any conflict between the
                    ------------
     provisions of this Agreement and the provisions of the Company's Memorandum
     of Association or Articles of Association then, subject to the provisions
     of British Virgin Islands law, the provisions of this Agreement shall
     prevail as between the parties hereto, and the parties hereto shall
     exercise all voting and other rights and powers legally available to them
     (whether as shareholders or otherwise) to give effect to the provisions of
     this Agreement. If there is an irreconcilable conflict between a provision
     of this Agreement and a mandatory provisions of British Virgin Islands law,
     the parties shall use their respective best efforts to agree on an
     alternative mechanism or

                                       15
<PAGE>

     provision which is as close as reasonably possible to the provisions of
     this Agreement and the conflicting provisions contained in this Agreement
     shall be invalid (but only to the extent necessary), provided that such
     invalidity shall not affect the other provisions of this Agreement. Except
     as provided in the preceding sentence, should any one or more of the
     provisions of this Agreement or of any agreement entered into pursuant to
     this Agreement be determined to be illegal or unenforceable, all other
     provisions of this Agreement and of each other agreement entered into
     pursuant to this Agreement, shall be given effect separately from the
     provision or provisions determined to be illegal or unenforceable and shall
     not be affected thereby.

               (d)  Assignment of Rights. The rights to cause the Company to
                    --------------------
     register Registrable Securities pursuant to Sections 3 and 4, and all
     related rights and benefits hereunder, including, without limitation,
     rights of indemnification under Section 7, may be assigned by a Holder to a
     transferee or assignee of Registrable Securities which is a Permitted
     Transferee of a Holder; provided, however, that (A) the transferor shall,
     within ten (10) days after such transfer, furnish to the Company written
     notice of the name and address of such transferee or assignee and the
     securities with respect to which such rights are being assigned, and (B)
     such transferee shall agree in writing to be subject to all restrictions
     set forth in this Agreement. Except as provided in the preceding sentence
     this Agreement and the rights and benefits hereunder shall not be
     assignable, except with the prior written consent of the Company and the
     Investors.

               (e)  Parties in Interest. All the terms and provisions of this
                    -------------------
     Agreement shall be binding upon and inure to the benefit of and be
     enforceable by the respective successors and permitted assigns of the
     parties hereto. Subject to the immediately preceding sentence, and except
     as set forth specifically in this Agreement, including, without limitation,
     in Section 7 hereof, this Agreement shall not run to the benefit of or be
     enforceable by any Person other than a party to this Agreement and its
     successors and permitted assigns.

               (f)  Headings. The headings of the sections, subsections and
                    --------
     paragraphs of this Agreement have been inserted for convenience of
     reference only and do not constitute a part of this Agreement.

               (g)  Choice of Law. It is the intention of the parties that the
                    -------------
     internal substantive laws, and not the laws of conflicts, of the State of
     California should govern the enforceability and validity of this Agreement,
     the construction of its terms and the interpretation of the rights and
     duties of the parties.

               (h)  Counterparts. This Agreement may be executed in any number
                    ------------
