                  2.3.     Demand Registration.

at any time after the earlier of (i) three (3) years after the date of this
Agreement or (ii) six (6) months following a Qualified Public Offering receive a
written request from the Holders of at least thirty percent (30%) of the
Registrable Securities then outstanding that the Company file a registration
statement under the Securities Act covering the registration of Registrable
Securities pursuant to this Section 2.3, then the Company shall, within ten (10)
business days of the receipt of such written request, give written notice of
such request ("REQUEST NOTICE") to all Holders, and use its best efforts to
effect, as soon as practicable, the registration under the Securities Act of all
Registrable Securities that the Holders request to be registered and included in
such registration by written notice given by such Holders to the Company within
twenty (20) days after receipt of the Request Notice, subject only to the
limitations of this Section 2.3; provided that the Company shall not be
obligated to effect any such registration if the Company has, within the six (6)
month period preceding the date of such request, already effected a registration
under the Securities Act pursuant to this Section 2.3 or Section 2.5 or in which
the Holders had an opportunity to participate pursuant to the provisions of
Section 2.4, other than a registration from which the Registrable Securities of
the Holders have been excluded (with respect to all or any portion of the
Registrable Securities the Holders requested be included in such registration)
pursuant to the provisions of Section 2.4(a).

                           (b)      Underwriting.  If the Holders initiating the
registration request under this Section 2.3 (the "INITIATING HOLDERS") intend to
distribute the Registrable Securities covered by their request by means of an
underwriting, then they shall so advise the Company as a part of their request
made pursuant to this Section 2.3 and the Company shall include such information
in the Request Notice. In such event, the right of any Holder to include its
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall enter into an underwriting agreement in customary form
with the managing underwriter or underwriters selected for such underwriting by
the Holders of a majority of the Registrable Securities being registered and
reasonably acceptable to the Company. Notwithstanding any other provision of
this Section 2.3, if the underwriter(s) advise(s) the Company in writing that
marketing factors require a limitation of the number of securities to be
underwritten then the Company shall so advise all Holders of Registrable
Securities which would otherwise be registered and underwritten pursuant hereto,

                                       4
<PAGE>

and the number of Registrable Securities that may be included in the
underwriting shall be reduced as required by the underwriter(s) and allocated,
first, to each of the Holders requesting inclusion of their Series B Registrable
Securities in such registration statement on a pro rata basis based on the total
number of Series B Registrable Securities held by each such Holder requesting
registration (including the Initiating Holders) and, second, to each of the
Holders requesting inclusion of their Series A Registrable Securities in such
registration statement on a pro rata basis based on the total number of Series A
Registrable Securities held by each such Holder requesting registration
(including the Initiating Holders); provided, however, that the number of shares
of Registrable Securities to be included in such underwriting and registration
shall not be reduced unless all other securities are first entirely excluded
from the underwriting and registration including, without limitation, all shares
that are not Registrable Securities and are held by any other person, including,
without limitation, any person who is an employee, officer or director of the
Company or any subsidiary of the Company; provided further, that (i) at least
twenty-five percent (25%) of shares of the Registrable Securities requested by
the Holders to be included in such underwriting and registration shall be so
included and (ii) Holders of Series A Registrable Securities shall be entitled
to be allocated at least one-seventh (1/7) of the total number of Registrable
Securities to be included in such underwriting and registration. If any Holder
disapproves of the terms of any such underwriting, such Holder may elect to
withdraw therefrom by written notice to the Company and the underwriter(s),
delivered at least ten (10) business days prior to the effective date of the
registration statement. Any Registrable Securities excluded or withdrawn from
such underwriting shall be excluded and withdrawn from the registration.

                           (c)      Maximum Number of Demand Registrations.
The Company shall not be obligated to effect more than three (3) such
registrations pursuant to this Section 2.3.

                           (d)      Deferral.  Notwithstanding the foregoing,
if the Company shall furnish to Holders requesting registration pursuant to this
Section 2.3, a certificate signed by the President or Chief Executive Officer of
the Company stating that in the good faith judgment of the Board, it would be
materially detrimental to the Company and its shareholders for such registration
statement to be filed, then 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 Holders; provided, however, that the Company may not
utilize this right more than once in any twelve (12) month period.

                           (e)      Expenses.  All expenses incurred in
connection with any registration pursuant to this Section 2.3, including without
limitation all U.S. federal, "blue sky" and all foreign registration, filing and
qualification fees, printer's and accounting fees, and fees and disbursements of
counsel for the Company and of counsel for the Holders (but excluding
underwriters' discounts and commissions relating to shares sold by the Holders),
shall be borne by the Company. Each Holder participating in a registration
pursuant to this Section 2.3 shall bear such Holder's proportionate share (based
on the total number of shares sold in such registration other than for the
account of the Company) of all discounts, and commissions or other amounts
payable to underwriter(s) or brokers, in connection with such offering by the
Holders. Notwithstanding the foregoing, the Company shall not be required to pay
for any expenses of any registration proceeding begun pursuant to this Section
2.3 if the registration request is subsequently withdrawn at the request of the
Holders of a majority of the Registrable Securities to be registered, unless the
Holders of a majority of the Registrable

                                       5
<PAGE>

Securities then outstanding agree that such registration constitutes the use by
the Holders of one (1) demand registration pursuant to this Section 2.3 (in
which case such registration shall also constitute the use by all Holders of
Registrable Securities of one (1) such demand registration); provided further,
however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business, or prospects of the Company
not known to the Holders at the time of their request for such registration and
have withdrawn their request for registration with reasonable promptness after
learning of such material adverse change, then the Holders shall not be required
to pay any of such expenses and such registration shall not constitute the use
of a demand registration pursuant to this Section 2.3.

                  2.4    Piggyback Registrations. The Company shall notify all
Holders of Registrable Securities in writing at least thirty (30) days prior to
filing any registration statement under the Securities Act for purposes of
effecting a public offering of securities of the Company (including, but not
limited to, registration statements relating to secondary offerings of
securities of the Company, but excluding registration statements relating to any
registration under Section 2.3 or Section 2.5 of this Agreement or to any
employee benefit plan or a corporate reorganization) and shall afford each such
Holder an opportunity to include in such registration statement all or any part
of the Registrable Securities then held by such Holder. Each Holder desiring to
include in any such registration statement all or any part of the Registrable
Securities held by it shall within twenty (20) days after receipt of the
above-described notice from the Company, so notify the Company in writing, and
in such notice shall inform the Company of the number of Registrable Securities
such Holder wishes to include in such registration statement. If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by
the Company with respect to offerings of its securities, all upon the terms and
conditions set forth herein.

                           (a)      Underwriting.  If a registration statement
under which the Company gives notice under this Section 2.4 is for an
underwritten offering, then the Company shall so advise the Holders of
Registrable Securities. In such event, the right of any such Holder's
Registrable Securities to be included in a registration pursuant to this Section
2.4 shall be conditioned upon such Holder's participation in such underwriting
and the inclusion of such Holder's Registrable Securities in the underwriting to
the extent provided herein. All Holders proposing to distribute their
Registrable Securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting. Notwithstanding any other provision
of this Agreement, if the managing underwriter(s) determine(s) in good faith
that marketing factors require a limitation of the number of shares to be
underwritten, then the managing underwriter(s) may exclude shares from the
registration and the underwriting, and the number of shares that may be included
in the registration and the underwriting shall be allocated, first, to the
Company, second, to each of the Holders requesting inclusion of their Series B
Registrable Securities in such registration statement on a pro rata basis based
on the total number of shares of Series B Registrable Securities then held by
each such Holder, and third, to each of the Holders requesting inclusion of
their Series A Registrable Securities in such registration statement on a pro
rata basis based on the total number of shares of Series A Registrable
Securities then held by each such Holder, and fourth, to holders of other
securities

                                       6
<PAGE>

of the Company; provided, however, that the right of the underwriter(s) to
exclude shares (including Registrable Securities) from the registration and
underwriting as described above shall be restricted so that (i) the number of
Registrable Securities included in any such registration is not reduced below
twenty-five percent (25%) of the aggregate number of shares of Registrable
Securities for which inclusion has been requested; (ii) all shares that are not
Registrable Securities and are held by any other person, including, without
limitation, any person who is an employee, officer or director of the Company
(or any subsidiary of the Company) shall first be excluded from such
registration and underwriting before any Registrable Securities are so excluded,
and (iii) Holders of Series A Registrable Securities shall be entitled to be
allocated at least one-seventh (1/7) of the total number of Registrable
Securities to be included in such underwriting and registration; unless such
offering is a Qualified Public Offering in which case all the Registrable
Securities may be excluded if the underwriters make the determination described
above and no other shareholder's securities are included. If any Holder
disapproves of the terms of any such underwriting, such Holder may elect to
withdraw therefrom by written notice tin the Company and the underwriter(s),
delivered at least ten (10) business days prior to the effective date of the
registration statement. Any Registrable Securities excluded or withdrawn from
such underwriting shall be excluded and withdrawn from the registration.

                           (b)      Expenses.  All expenses incurred in
connection with a registration pursuant to this Section 2.4 (excluding
underwriters' and brokers' discounts and commissions relating to shares sold by
the Holders), including, without limitation all U.S. federal, "blue sky" and all
foreign registration, filing and qualification fees, printers' and accounting
fees, and fees and disbursements of counsel for the Company and of counsel for
the Holders, shall be borne by the Company.

                           (c)      Not Demand Registration. Registration
pursuant to this Section 2.4 shall not be deemed to be a demand registration as
described in Section 2.3 above. Except as otherwise provided herein, there shall
be no limit on the number of times the Holders may request registration of
Registrable Securities under this Section 2.4.

                  2.5    Form S-3 or Form F-3 Registration. In case the Company
shall at any time after the first anniversary of the date hereof receive from
any Holder or Holders of a majority of all Registrable Securities then
outstanding a written request or requests that the Company effect a registration
on Form S-3 or Form F-3 (or an equivalent registration in a jurisdiction outside
of the United States) and any related qualification or compliance with respect
to all or a part of the Registrable Securities owned by such Holder or Holders,
then the Company will:

                           (a)      Notice.  Promptly give written notice of the
proposed registration and the Holder's or Holders' request therefor, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

                           (b)      Registration.  As soon as practicable,
effect such registration and all such qualifications and compliances as may be
so requested and as would permit or facilitate the sale and distribution of all
or such portion of such Holders or Holders' Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any other Holder or Holders joining in such request as are
specified in a written request given within twenty (20) days after the Company
provides the notice

                                       7
<PAGE>

contemplated by Section 2.5(a); provided, however, that the
Company shall not be obligated to effect any such registration, qualification or
compliance pursuant to this Section 2.5:

                                    (1)     if Form S-3 or Form F-3 is not
available for such offering by the Holders;

                                    (2)     if the Holders, together with the
holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) at an aggregate price to the public of less than US$500,000;

                                    (3)     if the Company shall furnish to the
Holders a certificate signed by the President or Chief Executive Officer of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, it would be materially detrimental to the Company and its shareholders
for such Form S-3 or Form F-3 Registration (or equivalent registration in a
jurisdiction outside of the United States) to be effected at such time, in which
event the Company shall have the right to defer the filing of the Form S-3 or
Form F-3 registration statement (or equivalent registration statement in a
jurisdiction outside of the United States) no more than once during any twelve
(12) month period for a period of not more than ninety (90) days after receipt
of the request of the Holder or Holders under this Section 2.5;

                                    (4)     if the Company has, within the six
(6) month period preceding the date of such request, already effected a
registration under the Securities Act other than a registration from which the
Registrable Securities of Holders have been excluded (with respect to all or any
portion of the Registrable Securities the Holders requested be included in such
registration) pursuant to the provisions of Section 2.4(a); or

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

                           (c)      Expenses.  The Company shall pay all
expenses incurred in connection with each registration requested pursuant to
this Section 2.5, (excluding underwriters' or brokers' discounts and commissions
relating to shares sold by the Holders), including without limitation all U.S.
federal, "blue sky" and all foreign registration, filing and qualification fees,
printers' and accounting fees, and fees and disbursements of counsel for the
Company and of counsel for the Holders.

                           (e)      Not Demand Registration.  Form S-3 or Form
F-3 registrations (or equivalent registrations outside of the United States)
shall not be deemed to be demand registrations as described in Section 2.3
above. Except as otherwise provided herein, there shall be no limit on the
number of times the Holders may request registration of Registrable Securities
under this Section 2.5.

the disposition of all securities covered by such registration statement.

                           (c)      Prospectuses.  Furnish to the Holders such
number of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents
as they may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by them that are included in such registration.

                           (d)      Blue Sky. Use its best efforts to register
and qualify the securities covered by such registration statement under such
other securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders, provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions.

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

                           (f)      Notification.  Notify each Holder of
Registrable Securities covered by such registration statement at any time when a
prospectus relating thereto is required to be delivered under the Securities Act
of the happening of any event as a result of which the prospectus included in
such registration statement, as then in effect, includes an untrue statement of
a material fact or omits to state a material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances then existing.

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

                                       9
<PAGE>

underwritten public offering and reasonably satisfactory to a majority in
interest of the Holders requesting registration, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

                  2.7    Furnish Information. It shall be a condition precedent
to the obligations of the Company to take any action pursuant to Sections 2.3,
2.4 or 2.5 that the selling Holders shall furnish to the Company such
information regarding themselves, the Registrable Securities held by then and
the intended method of disposition of such securities as shall be required to
timely effect the Registration of their Registrable Securities.

                  2.8      Indemnification.  In the event any Registrable
Securities are included in a registration statement under Sections 2.3, 2.4 or
2.5:

                           (a)      To the extent permitted  by law, the Company
will indemnify and hold harmless each Holder, its partners, officers, directors,
legal counsel, any underwriter (as determined in the Securities Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Securities Act or the Securities Exchange Act of 1934, as
amended, (the "1934 ACT"), against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the Securities Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "VIOLATION"):

                                    (i) any untrue statement or alleged untrue
                  statement of a material fact contained in such registration
                  statement, including any preliminary prospectus or final
                  prospectus contained therein or any amendments or supplements
                  thereto;

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

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

and the Company will reimburse each such Holder, its partner, officer, director,
legal counsel, underwriter or controlling person for any legal or other expenses
reasonably incurred by them, as incurred, in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 2.8(a) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld), nor shall the Company be liable in
any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by such Holder, underwriter or
controlling person of such Holder.

                                       10
<PAGE>

                           (b)      Notice.  Promptly after receipt by an
indemnified party under this Section 2.8 of notice of the commencement of any
action (including any governmental action), such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 2.8, deliver to the indemnifying party a written notice of the
commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party shall have the right to retain its own counsel, with
the fees and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party would
be inappropriate due to actual or potential conflict of interests between such
indemnified party and any other party represented by such counsel in such
proceeding. The failure to deliver written notice to the indemnifying party
within a reasonable time of the commencement of any such action shall relieve
such indemnifying party of liability to the indemnified party under this Section
2.8 to the extent the indemnifying party is prejudiced as a result thereof, but
the omission to so deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise
than under this Section 2.8.

                           (c)      Contribution.  In order to provide for just
and equitable contribution to joint liability under the Securities Act in any
case in which either (i) any indemnified party makes a claim for indemnification
pursuant to this Section 2.8 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 2.8 provides for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any indemnified party in
circumstances for which indemnification is provided under this Section 2.8;
then, and in each such case, the indemnified party and the indemnifying party
will contribute to the aggregate losses, claims, damages or liabilities to which
they may be subject (after contribution from others) in such proportion so that
a Holder (together with its related persons) is responsible for the portion
represented by the percentage that the public offering price of its Registrable
Securities offered by and sold under the registration statement bears to the
public offering price of all securities offered by and sold under such
registration statement, and the Company and other selling Holders are
responsible for the remaining portion; provided, however, that, in any such
case: (A) no Holder will be required to contribute any amount in excess of the
net proceeds to such Holder from the sale of all such Registrable Securities
offered and sold by such Holder pursuant to such registration statement; and (B)
no person or entity guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) will be entitled to contribution from
any person or entity who was not guilty of such fraudulent misrepresentation.

                           (e)      Survival.  The obligations of the Company
and Holders under this Section 2.8 shall survive the completion of any offering
of Registrable Securities in a registration statement, regardless of the
expiration of any statutes of limitation or extensions of such statutes.

                  2.9   Termination of the Company's Obligations. The Company
shall have no obligations pursuant to Sections 2.3, 2.4 and 2.5 with respect to
any Registrable Securities

                                       11
<PAGE>

proposed to be sold by a Holder in a registration pursuant to Section 2.3, 2.4
or 2.5 more than seven (7) years after the Closing, or, if, in the opinion of
counsel to the Company, all such Registrable Securities proposed to be sold by a
Holder may then be sold without registration in any ninety (90) day period
pursuant to Rule 144 promulgated under the Securities Act.

                  2.10   No Registration Rights to Third Parties. Without the
prior written consent of the Holders of a majority in interest of the
Registrable Securities then outstanding, the Company covenants and agrees that
it shall not grant, or cause or permit to be created, for the benefit of any
person or entity any registration rights of any kind (whether similar to the
demand, "piggyback" or Form S-3 or Form F-3 registration rights described in
this Section 2, or otherwise) relating to any securities of the Company which
are senior to, or on a parity with, those granted to the Holders of Registrable
Securities.

                  2.11   Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Registrable Securities to the public without registration
or pursuant to a registration on Form S-3 or F-3, after such time as a public
market exists for the Ordinary Shares, the Company agrees to:

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

                          (b)       Use reasonable, diligent efforts to file
with the SEC in a timely manner all reports and other documents required of the
Company under the Securities Act and the 1934 Act (at any time after it has
become subject to such reporting requirements); and

                           (c)      So long as a Holder owns any Registrable
Securities, to furnish to such Holder forthwith upon request (i) a written
statement by the Company as to its compliance with the reporting requirements of
Rule 144 (at any time after ninety (90) days after the effective date of the
Company's initial public offering), the Securities Act and the 1934 Act (at any
time after it has become subject to such reporting requirements), or its
qualification as a registrant whose securities may be resold pursuant to Form
S-3 or F-3 (at any time after it so qualifies), (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 a Holder may reasonably request in availing itself
of any rule or regulation of the SEC that permits the selling of any such
securities without registration or pursuant to Form S-3 or F-3.

                  2.12   Market Stand-Off. Each Founder and each Holder agrees
that, so long as it holds any voting securities of the Company, upon request by
the Company or the underwriters managing the initial public offering of the
Company's securities, it will not sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any securities of the
Company (other than those permitted to be included in the registration and other
transfers to affiliates permitted by law) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
not exceeding 180 days from the effective date of the registration statement
covering such initial public offering or the pricing date of such offering as
may be requested by the underwriters. The foregoing

                                       12
<PAGE>

provision of this Section 2.12 shall not apply to the sale of any securities of
the Company to an underwriter pursuant to any underwriting agreement, and shall
only be applicable to the Holders if all officers, directors and holders of
three percent (3%) or more of the Company's outstanding share capital enter into
similar agreements, and if the Company or any underwriter releases any officer,
director or holder of three percent (3%) or more of the Company's outstanding
share capital from his or her sale restrictions so undertaken, then each Holder
shall be notified prior to such release and shall itself be simultaneously
released to the same proportional extent. The Company shall require all future
acquirers of the Company's securities holding at least three percent (3%) of the
then outstanding share capital of the Company to execute prior to a Qualified
Public Offering a market stand-off agreement containing substantially similar
provisions as those contained in this Section 2.12.

         3.       RIGHT OF PARTICIPATION.

                  3.1    General. An Investor and any holder of Series A Shares
to which rights under this Section 3 have been duly assigned in accordance with
Section 5 (such Investor and each such assignee being hereinafter referred to as
a "PARTICIPATION RIGHTS HOLDER") shall have the right of first refusal to
purchase such Participation Rights Holder's Pro Rata Share (as defined below),
of all (or any part) of any New Securities (as defined in Section 3.3) that the
Company may from time to time issue after the date of this Agreement (the "RIGHT
OF PARTICIPATION").

                  3.2    Pro Rata Share. A Participation Rights Holder's "PRO
RATA SHARE" for purposes of the Right of Participation is the ratio of (a) the
number of Ordinary Shares (calculated on a fully-diluted and as-converted basis)
held by such Participation Rights Holder, to (b) the total number of Ordinary
Shares (calculated on a fully-diluted and as-converted basis) then outstanding
(immediately prior to the issuance of New Securities giving rise to the Right of
Participation).

                  3.3   New Securities. "NEW SECURITIES" shall mean any Ordinary
Shares, Series A Shares, Series B Shares, any other shares of the Company
designated as "Preferred Shares," or other voting shares of the Company, whether
now authorized or not, and rights, options or warrants to purchase such Ordinary
Shares, Series A Shares, Series B Shares, Preferred Shares, and securities of
any type whatsoever that are, or may become, convertible or exchangeable into
such Ordinary Shares, Series A Shares, Series B Shares, Preferred Shares, or
other voting shares, provided, however, that the term "New Securities" shall not
include:

                           (a)      up to 5,250,000 shares of the Company's
Ordinary Shares (and/or options or warrants therefor) issued to employees,
officers, directors, contractors, advisors or consultants of the Company
pursuant to incentive agreements or incentive plans approved by the Finance
Committee of the Board;

                           (b)      any shares of Series B Shares issued under
the Purchase Agreement, as such agreement may be amended;

                           (c)      any securities issued in connection with
any share split, share dividend or other similar event in which all
Participation Rights Holders are entitled to participate on a pro rata basis;

                                       13
<PAGE>

                           (d)      any securities issued upon the exercise,
conversion or exchange of any outstanding security if such outstanding security
constituted a New Security;

                           (e)      any securities issued pursuant to a
Qualified Public Offering; or

                           (f)      any securities issued pursuant to (i) the
acquisition of another corporation or entity by the Company by consolidation,
merger, purchase of assets, or other reorganization in which the Company
acquires, in a single transaction or series of related transactions, all or
substantially all assets of such other corporation or entity or fifty percent
(50%) or more of the equity ownership or voting power of such other corporation
or entity, or (ii) a merger, consolidation or other third party business
combination of the Company with or into any other business entity in which the
shareholders of the Company immediately after such merger, consolidation or
other business combination hold shares representing less than a majority of the
voting power of the outstanding share capital of the surviving business entity.

                  3.4      Procedures.

                           (a)      First Participation Notice.  In the event
that the Company proposes to undertake an issuance of New Securities (in a
single transaction or a series of related transactions), it shall give to each
Participation Rights Holder written notice of its intention to issue New
Securities (the "FIRST PARTICIPATION NOTICE"), describing the amount and the
type of New Securities and the price and the general terms upon which the
Company proposes to issue such New Securities. Each Participation Rights Holder
shall have ten (10) business days from the date of receipt of any such First
Participation Notice to agree in writing to purchase such Participation Rights
Holder's Pro Rata Share of such New Securities for the price and upon the terms
and conditions specified in the First Participation Notice by giving written
notice to the Company and stating therein the quantity of New Securities to be
purchased (not to exceed such Participation Rights Holder's Pro Rata Share). If
any Participation Rights Holder fails to so agree in writing within such ten
(10) business day period to purchase such Participation Rights Holder's full Pro
Rata Share of an offering of New Securities, then such Participation Rights
Holder shall forfeit the right hereunder to purchase that part of its Pro Rata
Share of such New Securities that it did not agree to purchase.

                           (b)      Second Participation Notice;
Oversubscription. If any Participating Rights Holder fails to exercise its Right
of Participation in accordance with subsection (a) above, the Company shall
promptly give notice (the "SECOND PARTICIPATION NOTICE") to other Participating
Rights Holders who exercised their Right of Participation (the "RIGHT
PARTICIPANTS") in accordance with subsection (a) above. Each Right Participant
shall have five (5) business days from the date of the Second Participation
Notice (the "SECOND PARTICIPATION PERIOD") to notify the Company of its desire
to purchase more than its Pro Rata Share of the New Securities, stating the
number of the additional New Securities it proposes to buy (the "ADDITIONAL
NUMBER"). Such notice may be made by telephone if confirmed in writing within in
two (2) business days. If, as a result thereof, such oversubscription exceeds
the total number of the remaining New Securities available for purchase, each
oversubscribing Right Participant will be cut back by the Company with respect
to its oversubscription to that number of remaining New Securities equal to the
lesser of (x) the Additional Number and (y) the product obtained by multiplying
(i) the number of the

                                       14
<PAGE>

remaining New Securities available for subscription by (ii) a fraction the
numerator of which is the number of Ordinary Shares (calculated on an
as-converted basis) held by such oversubscribing Right Participant and the
denominator of which is the total number of Ordinary Shares (calculated on an
as-converted basis) held by all the oversubscribing Right Participants. Each
Right Participant shall be obligated to buy such number of New Securities as
determined by the Company pursuant to this Section 3.4 and the Company shall so
notify the Right Participants within fifteen (15) business days following the
date of the Second Participation Notice.

                  3.5   Failure to Exercise. Upon the expiration of the Second
Participation Period, or in the event no Participation Rights Holder exercises
the Right of Participation, after ten (10) days following the issuance of the
First Participation Notice, the Company shall have 120 days thereafter to sell
the New Securities described in the First Participation Notice (with respect to
which the Right of Participation hereunder were not exercised) at the same or
higher price and upon non-price terms not materially more favorable to the
purchasers thereof than specified in the First Participation Notice. In the
event that the Company has not issued and sold such New Securities within such
120 day period, then the Company shall not thereafter issue or sell any New
Securities without again first offering such New Securities to the Participation
Rights Holders pursuant to this Section 3.

                  3.6   Termination. The Right of Participation for each
Participation Rights Holder shall not terminate so long as any Investor and its
Affiliates (as defined in Rule 144 under the Securities Act) collectively hold
any Series A Shares, Series B Shares or Ordinary Shares; provided, however, that
the Right of Participation shall terminate upon a Qualified Public Offering.

         4.       TRANSFER RESTRICTIONS.

                  4.1    Certain Definitions. For purposes of this Section 4,
"ORDINARY SHARES" means (i) the Company's outstanding Ordinary Shares, (ii) the
Ordinary Shares issued or issuable upon conversion of the Company's outstanding
preferred shares, (iii) the Ordinary Shares issuable upon exercise of
outstanding options or warrants and (iv) the Ordinary Shares issuable upon
conversion of any outstanding convertible securities; "RESTRICTED SHARES" means
the Company's Ordinary Shares and/or Series A Shares now owned or subsequently
acquired by any Founder; "SERIES B HOLDER" means a holder of any Series B
Shares.

                  4.2    Sale by Founder; Notice of Sale. Subject to Section 4.6
of this Agreement, if a Founder (the "SELLING SHAREHOLDER") proposes to sell or
transfer any Restricted Shares held by it, then the Selling Shareholder shall
promptly give written notice (the "TRANSFER NOTICE") to each Series B Holder
prior to such sale or transfer. The Notice shall describe in reasonable detail
the proposed sale or transfer including, without limitation, the number of
Restricted Shares to be sold or transferred (the "OFFERED SHARES"), the nature
of such sale or transfer, the consideration to be paid, and the name and address
of each prospective purchaser or transferee.

                  4.3    Right of First Refusal. Each Series B Holder will have
the right, exercisable upon written notice (the "FIRST REFUSAL NOTICE") to the
Selling Shareholder, the Company and each other Series B Holder within thirty
(30) days after receipt of the Transfer

                                       15
<PAGE>

Notice (the "FIRST REFUSAL PERIOD") of its election to exercise its right of
first refusal hereunder. The First Refusal Notice shall set forth the number of
Offered Shares that such Series B Holder wishes to purchase, which amount shall
not exceed the First Refusal Allotment (as defined below) of such Series B
Holder. Such right of first refusal may be exercised as follows:

                           (a)      First Refusal Allotment.  Each Series B
Holder shall have the right to purchase that number of the Offered Shares (the
"FIRST REFUSAL ALLOTMENT") equivalent to the product obtained by multiplying the
aggregate number of the Offered Shares by a fraction, the numerator of which is
the number of Ordinary Shares held by such Series B Holder at the time of the
transaction and the denominator of which is the total number of Ordinary Shares
owned by all the Series B Holders at the time of the transaction. Any Series B
Holder will not have a right to purchase any of the Offered Shares unless it
exercises its right of first refusal within the First Refusal Period to purchase
up to all of its First Refusal Allotment of the Offered Shares. To the extent
that any Series B Holder does not exercise its right of first refusal to the
full extent of its First Refusal Allotment, the Selling Shareholder and the
Series B Holders shall, within ten (10) days after the end of the First Refusal
Period, make such adjustments to the First Refusal Allotment of each exercising
Series B Holder so that any remaining Offered Shares may be allocated to those
Series B Holders exercising their rights of first refusal on a pro rata basis.

                           (b)      Expiration Notice.  Within ten (10) days
after expiration of the First Refusal Period the Company will give written
notice (the "FIRST REFUSAL EXPIRATION NOTICE") to the Selling Shareholder
specifying either (i) that all of the Offered Shares was subscribed by the
Series B Holders exercising their rights of first refusal or (ii) that the
Series B Holders have not subscribed all of the Offered Shares in which case the
First Refusal Expiration Notice will specify the Co-Sale Pro Rata Portion (as
defined below) of the remaining Offered Shares for the purpose of their co-sale
right described in Section 4.4 below.

                           (c)      Purchase Price.  The purchase price for the
Offered Shares to be purchased by the Series B Holders exercising their right of
first refusal will be the price set forth in the Transfer Notice, but will be
payable as set forth in this Section 4.3(c). If the purchase price in the
Transfer Notice includes consideration other than cash, the cash equivalent
value of the non-cash consideration will be determined by the Board in good
faith, which determination will be binding upon the Company, the Series B
Holders, and the Selling Shareholder, absent fraud or error.

                           (d)      Payment.  Payment of the purchase price for
the Offered Shares purchased by the Series B Holders shall be made within ten
(10) days following the date of the First Refusal Expiration Notice. Payment of
the purchase price will be made by wire transfer or check as directed by the
Selling Shareholder.

                           (e)      Rights as a Founder or Series B Holder.
If any Series B Holder exercises its right of first refusal to purchase the
Offered Shares, then, upon the date the notice of such exercise is given by such
Series B Holder, the Selling Shareholder will have no further rights as a holder
of such Offered Shares except the right to receive payment for such Offered
Shares from such Series B Holder in accordance with the terms of this Agreement,
and the Selling Shareholder will forthwith cause all certificate(s) evidencing
such Offered Shares to be surrendered to the Company for transfer to such Series
B Holder.

                                       16
<PAGE>

                           (f)      Application of Co-Sale Right.  If the Series
B Holders have not elected to purchase all of the Offered Shares, then the sale
of the remaining Offered Shares will become subject to the co-sale right set
forth in Section 4.4 below.

                  4.4    Co-Sale Right. To the extent that the Series B Holders
have not exercised their right of first refusal with respect to all the Offered
Shares, each Series B Holder shall have the right, exercisable upon written
notice (the "CO-SALE NOTICE") to the Selling Shareholder, the Company and each
other Series B Holder within thirty (30) days after receipt of the First Refusal
Expiration Notice (the "CO-SALE RIGHT PERIOD"), to participate in such sale of
the Restricted Shares on the same terms and conditions. The Co-Sale Notice shall
set forth the number of Ordinary Shares (on an as-converted basis) that such
participating Series B Holder wishes to include in such sale or transfer, which
amount shall not exceed the Co-Sale Pro Rata Portion (as defined below) of such
Series B Holder. To the extent one or more of the Series B Holders exercise such
right of participation in accordance with the terms and conditions set forth
below, the number of Restricted Shares that the Selling Shareholder may sell in
the transaction shall be correspondingly reduced. The co-sale right of each
Series B Holder shall be subject to the following terms and conditions:

                           (a)      Co-Sale Pro Rata Portion.  Each Series B
Holder may sell all or any part of that number of Ordinary Shares held by it
that is equal to the product obtained by multiplying (x) the aggregate number of
the Offered Shares subject to the co-sale right hereunder by (y) a fraction, the
numerator of which is the number of Ordinary Shares (on an as-converted basis)
owned by the Series B Holder at the time of the sale or transfer and the
denominator of which is the combined number of Ordinary Shares (on an
as-converted basis) at the time owned by all Series B Holders and fifty percent
(50%) of the Ordinary Shares (on an as-converted basis) convertible from the
Series A Shares held by the Founders ("CO-SALE PRO RATA PORTION"). To the extent
that any Series B Holder does not participate in the sale to the full extent of
its Co-Sale Pro Rata Portion, the Selling Shareholder and the participating
Series B Holders shall, within ten (10) days after the end of such Co-Sale Right
Period, make such adjustments to the Co-Sale Pro Rata Portion of each
participating Series B Holder so that any remaining Offered Shares may be
allocated to other participating Series B Holders on a pro rata basis.

                           (b)      Transferred Shares. Each participating
Series B Holder shall effect its participation in the sale by promptly
delivering to the Selling Shareholder for transfer to the prospective purchaser
one or more certificates, properly endorsed for transfer, which represent:

                                    (i)     the number of Ordinary Shares which
such Series B Holder elects to sell;

                                    (ii)    that number of Series B Shares which
is at such time convertible into the number of Ordinary Shares that such Series
B Holder elects to sell; provided, however, that if the prospective purchaser
objects to the delivery of Series B Shares in lieu of Ordinary Shares, such
Series B Holder shall convert such Series B Shares into Ordinary Shares and
deliver Ordinary Shares as provided in Subsection 4.4(b)(i) above. The Company
agrees to make any such conversion concurrent with the actual transfer of such
shares to the purchaser; or

                                       17
<PAGE>

                                    (iii)   a combination of the above.

                           (c)      Payment to Series B Holders.  The share
certificate or certificates that the participating Series B Holder delivers to
the Selling Shareholder pursuant to Section 4.4(b) shall be transferred to the
prospective purchaser in consummation of the sale of the Restricted Shares
pursuant to the terms and conditions specified in the Transfer Notice, and the
Selling Shareholder shall concurrently therewith remit to such Series B Holder
that portion of the sale proceeds to which such Series B Holder is entitled by
reason of its participation in such sale. To the extent that any prospective
purchaser or purchasers prohibits such assignment or otherwise refuses to
purchase shares or other securities from a Series B Holder exercising its
co-sale right hereunder, the Selling Shareholder shall not sell to such
prospective purchaser or purchasers any Restricted Shares unless and until,
simultaneously with such sale, the Selling Shareholder shall purchase such
shares or other securities from such Series B Holder.

                           (d)      Right to Transfer.  To the extent the Series
B Holders do not elect to purchase, or to participate in the sale of, the
Restricted Shares subject to the Transfer Notice, the Selling Shareholder may,
not later than ninety (90) days following delivery to the Company and each of
the Series B Holders of the Transfer Notice, conclude a transfer of the
Restricted Shares covered by the Transfer Notice and not elected to be purchased
by the Series B Holders on terms and conditions not materially different from
those described in the Transfer Notice. Any proposed transfer on terms and
conditions materially different from those described in the Transfer Notice, as
well as any subsequent proposed transfer of any Restricted Shares by the Selling
Shareholder, shall again be subject to the right of first refusal and the
co-sale rights of the Series B Holders and shall require compliance by the
Selling Shareholder with the procedures described in Section 4.3 and Section 4.4
of this Agreement.

                  4.5    Exempt Transfers. Notwithstanding anything to the
contrary herein and subject to Section 4.6(a) hereof, (i) the right of first
refusal and co-sale rights of the Series B Holders shall not apply to any sale
or transfer of the Restricted Shares to the Company pursuant to a repurchase
right or right of first refusal held by the Company in the event of a
termination of employment or consulting relationship, and (ii) the sale or
transfer of up to 3,150,000 Series A Shares by the Founders in the aggregate
shall not be subject to the co-sale rights of the Series B Holders.

                  4.6      Prohibited Transfers.

                           (a)      Notwithstanding anything to the contrary
contained herein, none of the Founders shall, without the prior written consent
of 66 2/3% in interest of the Ordinary Shares (on an as-converted basis) held by
the Investors, directly or indirectly, sell, assign, transfer, pledge,
hypothecate, mortgage, encumber or otherwise dispose through one or a series of
transactions the Ordinary Shares now held by such Founder to any person (i)
prior to the Qualified Public Offering or (ii) within 180 days following the
closing of a Qualified Public Offering.

                           (b)      Any attempt by a Founder to transfer
Restricted Shares in violation of Sections 4.3, 4.4 or 4.6(a) hereof shall be
void and the Company agrees it will not effect such a transfer nor will it treat
any alleged transferee as the holder of such shares

                                       18
<PAGE>

without the written consent of 66 2/3% in interest of the Ordinary Shares (on an
as-converted basis) held by the Investors.

                  4.7    Restriction on Indirect Transfers. Notwithstanding
anything to the contrary contained herein, without the prior written consent of
66 2/3% in interest of the Ordinary Shares (on an as-converted basis) held by
the Investors, (i) prior to the Qualified Public Offering or (ii) within 180
days following the closing of a Qualified Public Offering:

                           (a)      (i) Yunfan Zhou shall not directly or
indirectly, sell, assign, transfer, pledge, hypothecate, mortgage, encumber or
otherwise dispose through one or a series of transactions any equity interest
held by him in the BVI Shareholder to any person; and (ii) the BVI Shareholder
shall not issue to any person any equity securities of the BVI Shareholder or
any options or warrants for, or any other securities exchangeable for or
convertible into, such equity securities of the BVI Shareholder.

                           (b)      Each of Yunfan Zhou and Nick Yang shall not,
and shall not cause or permit any other person to, (i) directly or indirectly,
sell, assign, transfer, pledge, hypothecate, mortgage, encumber or otherwise
dispose through one or a series of transactions any equity interest held or
controlled by him in the PRC Affiliate to any person, and (ii) cause or permit
the PRC Affiliate to issue to any person any equity securities of the PRC
Affiliate or any options or warrants for, or any other securities exchangeable
for or convertible into, such equity securities of the PRC Affiliate.

                  4.8    BVI Shareholder. Yunfan Zhou shall deliver, or cause to
be delivered, to the Investors a copy of the Register of Members of the BVI
Shareholder certified by its agent in the British Virgin Islands as a true and
complete copy at the Closing (as defined in the Purchase Agreement) and every
six (6) months thereafter.

                  4.9      Legend.

                           (a)      Each certificate representing the Restricted
Shares now or hereafter owned by a Founder or issued to any person in connection
with a transfer in compliance with this Section 4 shall be endorsed with the
following legend:

                  "THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
                  REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
                  CONDITIONS OF A SHAREHOLDERS AGREEMENT BY AND BETWEEN THE
                  SHAREHOLDER, THE COMPANY, CERTAIN AFFILIATES OF THE COMPANY
                  AND CERTAIN SHAREHOLDERS OF THE COMPANY. COPIES OF SUCH
                  AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE
                  SECRETARY OF THE COMPANY."

                           (b)      Each Founder agrees that the Company may
instruct its transfer agent to impose transfer restrictions on the shares
represented by certificates bearing the legend referred to in Section 4.9(a)
above to enforce the provisions of this Agreement and the Company agrees to
promptly do so. The legend shall be removed upon termination of the provisions
of this Section 4.

<PAGE>

                  4.10    Term. Except for Sections 4.6 and 4.7, the provisions
under this Section 4 shall terminate upon the closing of a Qualified Public
Offering.

         5.       ASSIGNMENT AND AMENDMENT.

                  5.1      Assignment.  Notwithstanding anything herein to the
contrary:

                           (a)      Information Rights; Board Representation.
The rights of the Investors under Section 1.1 are transferable to any holder of
Series B Shares; provided, however, that no party may be assigned any of the
foregoing rights unless the Company is given written notice by the assigning
party stating the name and address of the assignee and identifying the
securities of the Company as to which the rights in question are being assigned;
and provided further, that any such assignee shall receive such assigned rights
subject to all the terms and conditions of this Agreement, including without
limitation the provisions of this Section 5. The rights of the Investors to
appoint directors under Section 1.2 shall not be transferable.

                           (b)      Registration Rights.  The registration
rights of the Holders under Section 2 hereof may be assigned to any Holder or to
any person acquiring Registrable Securities in a Permitted Transfer (as defined
below); provided, however, that no party may be assigned any of the foregoing
rights unless the Company is given written notice by the assigning party stating
the name and address of the assignee and identifying the securities of the
Company as to which the rights in question are being assigned; and provided
further, that any such assignee shall receive such assigned rights subject to
all the terms and conditions of this Agreement, including without limitation the
provisions of this Section 5. For purpose of this Section 5(b), a "PERMITTED
TRANSFER" means a transfer by an Investor to (i) any of its affiliates, or (ii)
any third party acquiring at least five percent (5%) of the Ordinary Shares held
by such Investor (calculated on an as-converted basis), excluding any person who
is engaged in substantially the same line(s) of business as is the Company or
any of the PRC Companies.

                           (c)      Rights of  Participation;  Right of First
Refusal; Co-Sale Rights. The rights of each Investor or each holder of Series B
Shares under Sections 3 and 4 hereof are fully assignable in connection with a
permitted transfer of shares of the Company by such Investor or holder of Series
B Shares; provided, however, that no party may be assigned any of the foregoing
rights unless the Company is given written notice by such Investor or holder of
Series B Shares at the time of such assignment stating the name and address of
the assignee and identifying the securities of the Company as to which the
rights in question are being assigned; and provided further, that any such
assignee shall receive such assigned rights subject to all the terms and
conditions of this Agreement.

                  5.2 Amendment of Rights. Any provision in this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only by the
written consent of (i) as to the Company, only by the Company; (ii) as to the
Investors, by persons or entities holding at least 66 2/3% of the Ordinary
Shares (calculated on an as-converted basis) held by the Investors and their
assignees pursuant to Section 5.1 hereof; provided, however, that any Investor
may waive any of its rights hereunder without obtaining the consent of any other
Investor; and (iii) as to the Founders, by persons holding a majority in
interest of the Ordinary Shares and Series

                                       20
<PAGE>

A Shares, collectively, held by the Founders and their assignees pursuant to
Section 5.1 hereof; provided, however, that any Founder may waive any of its
rights hereunder without obtaining the consent of any other Founder. Any
amendment or waiver effected in accordance with this Section 5.2 shall be
binding upon the Company, each Investor, each Founder and their respective
assigns.

         6.       CONFIDENTIALITY AND NON-DISCLOSURE.

                  6.1    Disclosure of Terms. The terms and conditions of this
Agreement, the Purchase Agreement, the Restructuring Documents and any Ancillary
Agreements (as defined in the Purchase Agreement), and all exhibits and
schedules attached to such agreements (collectively, the "FINANCING TERMS"),
including their existence, shall be considered confidential information and
shall not be disclosed by any party hereto to any third party except in
accordance with the provisions set forth below.

                  6.2    Press Releases. Any press release issued by the Company
shall not disclose any of the Financing Terms and the final form of such press
release shall be approved in advance in writing by the Investors. No other
announcement regarding any of the Financing Terms in a press release,
conference, advertisement, announcement, professional or trade publication, mass
marketing materials or otherwise to the general public may be made without the
Investors' prior written consent.

                  6.3    Permitted Disclosures. Notwithstanding the foregoing,
(i) any party may disclose the existence of the financing (but not any of the
Financing Terms) to any third party, and (ii) any party may disclose any of the
Financing Terms to its current or bona fide prospective investors, employees,
investment bankers, lenders, partners, accountants and attorneys, in each case
only where such persons or entities are under appropriate nondisclosure
obligations.

                  6.4    Legally Compelled Disclosure. In the event that any
party is requested or becomes legally compelled (including without limitation,
pursuant to securities laws and regulations) to disclose the existence of this
Agreement and the Purchase Agreement, and exhibits and schedules attached to
such agreements, or any of the Financing Terms hereof in contravention of the
provisions of this Section 6, such party (the "DISCLOSING PARTY") shall provide
the other parties (the "NON-DISCLOSING PARTIES") with prompt written notice of
that fact and use all reasonable efforts to seek (with the cooperation and
reasonable efforts of the other parties) a protective order, confidential
treatment or other appropriate remedy. In such event, the Disclosing Party shall
furnish only that portion of the information which is legally required and shall
exercise reasonable efforts to keep confidential such information to the extent
reasonably requested by any Non-Disclosing Party.

                  6.5    Other Information. The provisions of this Section 6
shall be in addition to, and not in substitution for, the provisions of any
separate nondisclosure agreement executed by any of the parties hereto with
respect to the transactions contemplated hereby.

                  6.6      Notices.  All notices required under this section
shall be made pursuant to Section 7.1 of this Agreement.

         7.       GENERAL PROVISIONS.

                   Each person making a communication hereunder by facsimile
shall promptly confirm by telephone to the person to whom such communication was
addressed each communication made by it by facsimile pursuant hereto but the
absence of such confirmation shall not affect the validity of any such
communication. A party may change or supplement the addresses given above, or
designate additional addresses, for purposes of this Section 7.1 by giving the
other party written notice of the new address in the manner set forth above.

                  7.2    Entire Agreement. This Agreement, the Purchase
Agreement, the Restructuring Documents and any Ancillary Agreements, together
with all the exhibits hereto and thereto, constitute and contain the entire
agreement and understanding of the parties with respect to the subject matter
hereof and supersedes any and all prior negotiations, correspondence,
agreements, understandings, duties or obligations between the parties respecting
the subject matter hereof.

                  7.3    Governing Law. This Agreement shall be governed by and
construed exclusively in accordance the internal laws of the State of New York
as applied to agreements entered into and to be performed entirely within such
state, excluding that body of law relating to conflict of laws and choice of
law.

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

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

                  7.6    Successors and Assigns. Subject to the provisions of
Section 5.1, the provisions of this Agreement shall inure to the benefit of, and
shall be binding upon, the successors and permitted assigns of the parties
hereto.

                  7.7    Interpretation; Captions. This Agreement shall be
construed according to its fair language. The rule of construction to the effect
that ambiguities are to be resolved against the drafting party shall not be

<PAGE>

                  7.8    Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                  7.9    Adjustments for Share Splits, etc. Wherever in this
Agreement there is a reference to a specific number of shares of Series A
Shares, Series B Shares or Ordinary Shares of the Company, then, upon the
occurrence of any subdivision, combination or share dividend of the Series A
Shares, Series B Shares or Ordinary Shares, the specific number of shares so
referenced in this Agreement shall automatically be proportionally adjusted to
reflect the effect on the outstanding shares of such class or series of shares
by such subdivision, combination or share dividend (calculated on an
as-converted basis).

                  7.10   Aggregation of Shares. All Series A Shares, Series B
Shares or Ordinary Shares held or acquired by affiliated entities or persons
shall be aggregated together for the purpose of determining the availability of
any rights under this Agreement.

                  7.11   Shareholders Agreement to Control. If and to the extent
that there are inconsistencies between the provisions of this Agreement and
those of the Memorandum and Articles, the terms of this Agreement shall control.
The parties hereto agree to take all actions necessary or advisable, as promptly

Memorandum and Articles so as to eliminate such inconsistency.

                           (a)      Negotiation Between Parties; Mediations.
The parties agree to negotiate in good faith to resolve any dispute between them
regarding this Agreement. If the negotiations do not resolve the dispute to the
reasonable satisfaction of all parties, then each party shall nominate a
representative (who shall be a senior officer of the rank of Vice President or
higher if such party is a business entity). These representatives shall, within
thirty (30) days of a written request by any party to call such a meeting, meet
in person and alone (except for one assistant for each party) and shall attempt
in good faith to resolve the dispute. If the disputes cannot be resolved by such
senior managers in such meeting, the parties agree that they shall, if requested
in writing by either party, meet within thirty (30) days after such written
notification for one day with an impartial mediator and consider dispute
resolution alternatives other than formal arbitration. If an alternative method
of dispute resolution is not agreed upon within thirty (30) days after the one
day mediation, either party may begin formal arbitration proceedings to be
conducted in accordance with subsection (b) below. This procedure shall be a
prerequisite before taking any additional action hereunder.

                           (b)      Arbitration.  In the event the parties are
unable to settle a dispute between them regarding this Agreement in accordance
with subsection (a) above, such dispute shall be referred to and finally settled
by arbitration at Hong Kong International Arbitration Centre in accordance with
the UNCITRAL Arbitration Rules (the "UNCITRAL RULES") in effect, which rules are
deemed to be incorporated by reference into this subsection (b). The arbitration
tribunal shall consist of three arbitrators to be appointed according to the
UNCITRAL Rules. The language of the arbitration shall be English.
