     9.6 BOARD OF DIRECTORS.

     (i) The Board of Directors shall consist of seven (7) directors. So long as
at least 40% of the Series A Preferred Shares purchased by the Investors remain
outstanding (as appropriately adjusted for share splits, share dividends,
recapitalizations and similar transactions), the holders of such Series A

Directors. In such case, the two (2) Investors holding the greatest number of
Series A Preferred Shares shall each have the right to nominate one (1)
director. If less than 40% but at least 20% of the Series A Preferred Shares
purchased by the Investors remain outstanding, the holders of such Series A
Preferred Shares shall have the right to appoint one (1) member of the Board of
Directors. In such case, the Investor holding the greatest number of Series A
Preferred Shares shall have the right to nominate the sole Series A director. In
each case the remaining directors shall be nominated, elected and removed by the

Articles. The directors designated by the Investors will be entitled to be
members of all board committees. The applicable Investors shall have the sole
right to remove their respective nominees and to reappoint successor directors;
other directors shall be nominated, elected and removed in accordance with the
Company's Memorandum and Articles. Each Party to this Agreement shall vote the
Ordinary Shares and Series A Preferred Shares owned by them to elect the two (2)
directors nominated by the applicable Investors. If there is a vacancy in the
membership of the Board of Directors at any time, whether due to death,
resignation, removal or some other cause, the Parties to this Agreement shall
cause that vacancy to be filled by a person nominated by the party or parties
hereto that originally nominated the predecessor director. The Parties to this
Agreement shall vote the Ordinary Shares and Series A Preferred Shares owned by
them to remove any director only if so requested by the party or parties hereto
that originally nominated such director and directors nominated by the
applicable Investors shall not be removed except if so requested. If there is a
vacancy in the membership of the Board of Directors, no action by the Board of
Directors shall be taken until the vacancy is filled, pursuant to the foregoing
provisions of this paragraph; provided, however, that, if the party or parties
hereto with the right to designate a director to fill a vacancy on the Board of
Directors pursuant to the foregoing provision of this paragraph fails to make
such designation within five (5) Business Days of the opening of that vacancy,
the Board of Directors may take action without waiting for such vacancy to be
filled, subject at all times to the provisions of Section 9.7.

     (ii) Meetings of the Board of Directors shall be held at least once per
calendar quarter. The number of directors necessary to constitute a quorum at
any regular or special meeting of the Board of Directors of the Company shall be

Directors may participate in the meeting and vote via telephone conference. The
Company shall promptly prepare and distribute to all Investors minutes of all
Board of Directors' meetings.

Company, to appoint an individual (an "OBSERVER") to attend any meetings of such

To the extent any holder of Series A Preferred Shares (or Ordinary Shares issued
on conversion thereof) transfers all such shares to any other Person, such
holder may assign its rights under this paragraph (iii) to such Person. The
Observer shall strictly maintain the confidentiality of any and all information
obtained by him at, resulting from or by reason of such board or committee
meeting ("BOARD INFORMATION"), and shall not use or disclose such information
for any purpose at any time, unless and until such information otherwise becomes
public. For the avoidance of doubt, the Observer may disclose Board Information
to his or her fund employer, its investors, the fund manager and the employees
thereof on an as-needed basis and so long as such Persons are under appropriate
nondisclosure obligations.

     (iv) Each of the Parties to this Agreement shall vote any shares of the
Company held thereby and if applicable, cause its respective representatives on
the Board to, and the Company shall, and the

                                       20

securities may be qualified or Registered in a jurisdiction other than the
United States of America for offering to the public or that the Company might
effect an offering in the United States of America in the form of American
Depositary Receipts. Accordingly,

     (a) It is their intention that, whenever this Exhibit K refers to a law or
institution of the United States of America but the parties wish to effectuate
qualification or Registration in a different jurisdiction, reference in this
Exhibit K to the laws or institutions of the United States shall be read as
referring, mutatis mutandis, to the comparable laws or institutions of the
jurisdiction in question; and

     (b) It is agreed that the Company will not undertake any listing of
American Depositary Receipts or any other security derivative of the Ordinary
Shares unless arrangements have been made satisfactory to a Holder Majority to
ensure that the spirit and intent of this Exhibit K will be realized and that
the Company is committed to take such actions as are necessary such that the
Holders will enjoy rights corresponding to the rights hereunder to sell their
Registrable Securities in a public offering in the United States of America as
if the Company had listed Ordinary Shares in lieu of such derivative securities.

2. DEMAND REGISTRATION.

     2.1 REGISTRATION OTHER THAN ON FORM F-3. Subject to the terms of this
Exhibit K, following the earlier of an IPO and the third anniversary of the
Share Purchase Agreement, a Holder Majority may request the Company in writing
to effect the Registration of Registrable Securities for which the reasonably
anticipated aggregate price to the public, net of Selling Expenses, would be of
at least US$5,000,000. Upon receipt of such a request, the Company shall (a)
promptly give written notice of the proposed Registration to all other Holders
and (b) as soon as practicable, cause the Registrable Securities specified in
the request, together with any Registrable Securities of any Holder who requests
in writing to join such Registration within fifteen (15) days after the
Company's delivery of written notice, to be Registered and/or qualified for sale
and distribution in such jurisdictions as the Initiating Holders may reasonably
request; provided that the Company shall use its best efforts to cause such
Registration and/or qualification to be complete within sixty (60) days of the
receipt of such request. The Company shall be obligated to effect no more than
two (2) Registrations pursuant to this Section 2.1.

                                     Exh L-3
<PAGE>
2.2 REGISTRATION ON FORM F-3. Subject to the terms of this Exhibit K, at any
time, and from time to time, after the date that is one year after an IPO, a
Holder Majority may request the Company in writing to file a Registration
Statement on Form F-3 or Form S-3 (or any successor form to Form F-3 or Form
S-3, or any comparable form for Registration in a jurisdiction other than the
United States) for a public offering of Registrable Securities for which the
reasonably anticipated aggregate price to the public, net of Selling Expenses,
would be at least US$1,000,000, insofar as the Company is entitled to use Form
F-3, Form S-3 or a comparable form to Register the requested Registrable
Securities. Upon receipt of such a request, the Company shall (i) promptly give
written notice of the proposed Registration to all other Holders and (ii) as
soon as practicable, cause the Registrable Securities specified in the request,
together with any Registrable Securities of any Holder who requests in writing
to join such Registration within fifteen (15) days after the Company's delivery
of written notice, to be Registered and qualified for sale and distribution in
such jurisdictions as the Initiating Holders may reasonably request; provided,
that the Company shall use its best efforts to cause such Registration and/or
qualification to be complete within sixty (60) days of the receipt of such
request.

2.3 RIGHT OF DEFERRAL.

     (a) The Company shall not be obligated to Register or qualify Registrable
Securities pursuant to this Section 2, if:

          (i) within ten (10) days of the receipt of any request of the Holders
to Register any Registrable Securities pursuant to Section 2.1 or Section 2.2,
the Company delivers written notice to the Initiating Holders of its bona fide
intention to effect the filing for its own account of a Registration Statement
with the Commission within sixty (60) days of receipt of that request (other
than a registration of securities in a transaction under Rule 145 of the
Securities Act or an offering solely to employees), provided that the Company is
actively employing in good faith all reasonable efforts to cause that
Registration Statement to become effective as soon as practicable; or

          (ii) within six (6) months immediately following the effective date of
any Registration Statement pertaining to the securities of the Company (other
than a registration of securities in a transaction under Rule 145 of the
Securities Act or with respect to an employee benefit plan).

     (b) If, after receiving a request from Holders pursuant to Section 2.1 or
Section 2.2 hereof, the Company furnishes to the Holders a certificate signed by
the Chief Executive Officer of the Company stating that, in the good faith
judgment of the Board, it would be seriously and materially detrimental to the
Company or its shareholders for a Registration Statement to be filed in the near
future, then the Company shall have the right to defer such filing for a period
during which such filing would be seriously detrimental, provided that such
deferral by the Company shall not exceed sixty (60) days from the receipt of any
request duly submitted by Holders under Section 2.1 or Section 2.2 to Register
Registrable Securities; provided, however, that the Company shall not utilize
this right more than once in any twelve (12) month period.

2.4 UNDERWRITTEN OFFERINGS. If, in connection with a request to Register
Registrable Securities under Section 2.1 or Section 2.2, the Initiating Holders
seek to distribute such Registrable Securities in an underwriting, they shall so
advise the Company as a part of the request, and the Company shall include such
information in the written notice to the other Holders described in Sections 2.1
and 2.2. 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
Initiating Holders representing a majority in voting power of the Registrable
Securities held by the Initiating Holders) 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 underwriter or
underwriters selected for such underwriting by the Initiating Holders
representing a majority in voting power of the Registrable Securities held by
the Initiating Holders. Notwithstanding any other

                                     Exh L-4
<PAGE>
provision of this Exhibit K, if the managing underwriter advises the Company
that marketing factors (including the aggregate number of securities requested
to be Registered, the general condition of the market, and the status of the
Persons proposing to sell securities pursuant to the Registration) require a
limitation of the number of Equity Securities to be underwritten, the
underwriters may exclude such number of Registrable Securities from the
underwriting as required after excluding any other Equity Securities (including,
without limitation, any Equity Securities which the Company may seek to include
in the underwriting for its own account all Equity Securities that are not
Registrable Securities and held by persons other than Holders) from the
underwriting. If a limitation of the number of Registrable Securities is
required pursuant to this Section 2.4, the number of Registrable Securities that
may be included in the underwriting by selling Holders shall be allocated among
such Holders, in proportion, as nearly as practicable, to the respective amounts
of Registrable Securities which the Holders would otherwise be entitled to
include in the Registration. Any Registrable Securities excluded or withdrawn
from such underwriting shall be withdrawn from the Registration.

3. PIGGYBACK REGISTRATIONS.

     3.1 REGISTRATION OF THE COMPANY'S SECURITIES. Subject to Section 3.3, if
the Company proposes to Register any Equity Securities for its own account or
for the account of any Person that is not a Holder, then in connection with the
public offering of such securities, the Company shall promptly give each Holder
written notice of such Registration and, upon the written request of any Holder
given within twenty (20) days after delivery of such notice, the Company shall
use its best efforts to include in such Registration any Registrable Securities
thereby requested by such Holder. If a Holder decides not to include all or any
of its Registrable Securities in such Registration 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.

     3.2 RIGHT TO TERMINATE REGISTRATION. The Company shall have the right to
terminate or withdraw any Registration initiated by it under Section 3.1 prior
to the effectiveness of such Registration, whether or not any Holder has elected
to participate therein. The expenses of such withdrawn Registration shall be
borne by the Company in accordance with Section 4.3.

     3.3 UNDERWRITING REQUIREMENTS.

     (a) In connection with any offering involving an underwriting of the
Company's Equity Securities, the Company shall not be required to Register the
Registrable Securities of a Holder under this Section 3 unless such Holder's
Registrable Securities are included in the underwriting and such Holder enters
into an underwriting agreement in customary form with the underwriters selected
by the Company and setting forth such terms for the underwriting as have been
agreed upon between the Company and the underwriters. In the event the
underwriters advise Holders seeking Registration of Registrable Securities
pursuant to this Section 3 in writing that market factors (including the
aggregate number of Registrable Securities requested to be Registered, the
general condition of the market, and the status of the persons proposing to sell
securities pursuant to the Registration) require a limitation of the number of
Equity Securities to be underwritten, the underwriters may exclude some or all
Registrable Securities from the Registration and underwriting after excluding
any other Equity Securities (including, without limitation, all Equity
Securities that are not Registrable Securities and held by persons other than
Holders) from the underwriting, and the number of Equity Securities and
Registrable Securities that may be included in the Registration and the
underwriting shall be allocated (i) first, to the Company, (ii) second, among
the Holders requesting inclusion of their Registrable Securities in such
Registration Statement in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities which the Holders would otherwise
be entitled to include in the Registration and (iii) third, to any other
shareholder other than a Holder on a pro rata basis; provided, that the right of
the underwriter to exclude any Registrable Securities from the Registration and
underwriting as described above shall be restricted such that Registrable
Securities requested to be included by the Holders may not be reduced below 25%
of the Ordinary Shares to be included in the Registration and underwriting, as
determined on a fully-diluted,

                                     Exh L-5
<PAGE>
as-converted basis, and in no event shall participation in the Registration by a
shareholder other than a Holder exclude a Holder from the Registration.

     (b) If any Holder disapproves of the terms of any underwriting, the Holder
may elect to withdraw therefrom by written notice to the Company and the
underwriters delivered at least ten (10) days prior to the effective date of the
Registration Statement. Any Registrable Securities excluded or withdrawn from
the underwriting shall be withdrawn from the Registration.

     3.4 EXEMPT TRANSACTIONS. The Company shall have no obligation to Register
any Registrable Securities under this Section 3 in connection with a
Registration by the Company (i) relating solely to the sale of securities to
participants in a Company stock plan, (ii) relating to a corporate
reorganization or other transaction under Rule 145 of the Securities Act (or
comparable provision under the laws of another jurisdiction, as applicable), or
(iii) on any form that does not include substantially the same information as
would be required to be included in a Registration Statement covering the sale
of the Registrable Securities.

4. PROCEDURES.

     4.1 REGISTRATION PROCEDURES AND OBLIGATIONS. Whenever required under this
Exhibit K to effect the Registration of any Registrable Securities held by the
Holders, the Company shall, as expeditiously as possible:

     (a) Prepare and file with the Commission a Registration Statement with
respect to those Registrable Securities and use its best efforts to cause that
Registration Statement to become effective, and, upon the request of the Holders
holding a majority of the Registrable Securities Registered thereunder, keep the
Registration Statement effective;

     (b) Prepare and file with the Commission amendments and supplements to that
Registration Statement and the prospectus used in connection with the
Registration Statement as may be necessary to comply with the provisions of
Applicable Securities Law with respect to the disposition of all securities
covered by the Registration Statement;

     (c) Furnish to the Holders the number of copies of a prospectus, including

the securities covered by the Registration Statement under the securities laws
of any jurisdiction, as reasonably requested by the Holders, provided that the
Company shall not be required to qualify to do business or file a general
consent to service of process in any such jurisdictions, and provided further
that in the event any jurisdiction in which the securities shall be qualified
imposes a non-waivable requirement that expenses incurred in connection with the
qualification of the securities be borne by selling shareholders, those expenses
shall be payable pro rata by selling shareholders;

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

     (f) Notify each Holder of Registrable Securities covered by the
Registration Statement at any time when a prospectus relating thereto is
required to be delivered under Applicable Securities Law or of the happening of
any event as a result of which any prospectus included in the 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) Provide a transfer agent and registrar for all Registrable Securities
Registered

                                     Exh L-6

by the Committee on Uniform Securities Identification Procedures for all those
Registrable Securities, in each case not later than the effective date of the
Registration;

     (h) Furnish, at the request of any Holder requesting Registration of
Registrable Securities pursuant to this Exhibit K, on the date that such
Registrable Securities are delivered for sale in connection with a Registration
pursuant to this Exhibit K, (i) an opinion, dated the date of the sale, of the
counsel representing the Company for the purposes of the Registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering; and (ii) a comfort letter dated the date of the sale, from the
independent certified public accountants of the Company, in form and substance
as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters;

     (i) Take all reasonable action necessary to list the Registrable Securities
on the primary exchange upon which the Company's securities are traded or, in
connection with an IPO, the primary exchange upon which the Company's securities
will be traded; and

     (j) Make its officers and management team available for investor road shows
and other meetings as deemed necessary by the Holders or the underwriters.

     4.2 INFORMATION FROM HOLDER. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Exhibit K with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the Registration of such Holder's Registrable
Securities.

     4.3 EXPENSES OF REGISTRATION. All expenses, other than Selling Expenses,
incurred in connection with Registrations, filings or qualifications pursuant to
this Exhibit K, including (without limitation) all Registration, filing and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company, underwriters, and any selling Holders, shall be borne
by the Company.

     4.4 DELAY OF REGISTRATION. No Holder shall have any right to obtain or seek
an injunction restraining or otherwise delaying any Registration as the result
of any controversy that may arise with respect to the interpretation or
implementation of this Exhibit K.

5. INDEMNIFICATION.

     5.1 COMPANY INDEMNITY.

     (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, such Holder's officers, directors, shareholders, legal
counsel and accountants, any underwriter (as defined in the Securities Act) for
such Holder and each Person, if any, who controls (as defined in the Securities
Act) such Holder or underwriter against any losses, claims, damages or
liabilities (joint or several) to which they may become subject under laws which
are applicable to the Company and relate to action or inaction required of the
Company in connection with any Registration, qualification, or compliance,
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 (each 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 in the Registration Statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, 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 Applicable Securities Laws, or any rule or
regulation promulgated under Applicable Securities Laws. The Company will
reimburse each such Holder, underwriter or controlling person for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such

                                     Exh L-7
<PAGE>
loss, claim, damage, liability or action.

     (b) The indemnity agreement contained in this Section 5.1 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 that occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such Registration by any such Holder, underwriter or
controlling person.

     (c) With respect to any preliminary prospectus, the foregoing indemnity
shall not inure to the benefit of any Holder or underwriter, or any Person
controlling (within the meaning of the Securities Act) such Holder or
underwriter, from whom the Person asserting any such losses, claims, damages or
liabilities purchased shares in the offering, if a copy of the prospectus (as
then amended or supplemented if the Company shall have furnished any amendments
or supplements thereto) was not sent or given by or on behalf of such Holder or
underwriter to such Person, if required by law so to have been delivered, at or
prior to the written confirmation of the sale of the shares to such Person, and
if the prospectus (as so amended or supplemented) would have cured the defect
giving rise to such loss, claim, damage or liability.

     5.2 HOLDER INDEMNITY.

     (a) To the extent permitted by law, each selling Holder will, severally and
not jointly, indemnify and hold harmless the Company, its directors, officers,
legal counsel and accountants, any underwriter, any other Holder selling
securities in connection with such Registration and each Person, if any, who
controls (within the meaning of the Securities Act) the Company, such
underwriter or other Holder, against any losses, claims, damages or liabilities
(joint or several) to which any of the foregoing persons may become subject,
under Applicable Securities Laws, or any rule or regulation promulgated under
Applicable Securities Laws, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such Registration;
and each such Holder will reimburse any person intended to be indemnified
pursuant to this Section 5.2, for any legal or other expenses reasonably
incurred by such person in connection with investigating or defending any such
loss, claim, damage, liability or action.

     (b) The indemnity contained in this Section 5.2 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 Holder (which consent shall
not be unreasonably withheld), and in no event shall any indemnity under this
Section 5.2 exceed the net proceeds from the offering received by such Holder.

     5.3 NOTICE OF INDEMNIFICATION CLAIM. Promptly after receipt by an
indemnified party under Section 5.1 or Section 5.2 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
Section 5.1 or Section 5.2, 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 indemnifying parties. An
indemnified party (together with all other indemnified parties that may be
represented without conflict by one counsel) shall have the right to retain one
separate counsel, with the reasonably incurred 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 differing 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, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the

                                     Exh L-8
<PAGE>
indemnified party under this Section 5, but the omission to 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 5.

     5.4 CONTRIBUTION. If any indemnification provided for in Section 5.1 or
Section 5.2 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage or expense
referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party, on the one hand, and of the indemnified party, on the
other, in connection with the statements or omissions that resulted in such
loss, liability, claim, damage or expense, 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 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.

     5.5 UNDERWRITING AGREEMENT. To the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

     5.6 SURVIVAL. The obligations of the Company and Holders under this Section
5 shall survive the completion of any offering of Registrable Securities in a
Registration Statement under this Exhibit K, and otherwise.

6. ADDITIONAL UNDERTAKINGS.

     6.1 REPORTS UNDER THE EXCHANGE ACT. With a view to making available to the
Holders the benefits of Rule 144 promulgated under the Securities Act and any
comparable provision of any Applicable Securities Law that may at any time
permit a Holder to sell securities of the Company to the public without
Registration or pursuant to a Registration on Form F-3 or Form S-3 (or any
comparable form in a jurisdiction other than the United States), the Company
agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in Commission Rule 144 (or comparable provision under
Applicable Securities Laws in any jurisdiction where the Company's securities
are listed), at all times following ninety (90) days after the effective date of
a Qualified IPO;

          (b) file with the Commission in a timely manner all reports and other
documents required of the Company under all Applicable Securities Laws; and

          (c) at any time following sixty (60) days after the effective date of
an initial public offering by the Company, promptly furnish to any Holder
holding Registrable Securities, upon request (i) a written statement by the
Company that it has complied with the reporting requirements of all Applicable

include such securities in any Registration filed under Section 3, unless under

the Holders that are included, or (c) allow such holder or prospective holder to

Exhibit K in the specific manner in which the Holder proposes to dispose of
Registrable Securities included in that request (including, without limitation,

the Company is, within a reasonable time after such transfer, furnished with
written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned;
and (b) such transferee or assignee agrees in writing to be bound by and subject

<PAGE>

     treatment or other appropriate remedy. In such event, the Disclosing Party
     shall furnish only that portion of the information which is legally
     required and shall exercise reasonable efforts to obtain reliable assurance
     that confidential treatment will be accorded such information.

9.4  Other Exceptions. Notwithstanding any other provision of this Section 9,
     the confidentiality obligations of the parties shall not apply to: (a)

     applicable securities law or regulations of the United States of America or
     requirement of any stock exchange or automated trading system; (b)
     information which a restricted party learns from a third party having the
     right to make the disclosure, provided the restricted party complies with
     any restrictions imposed by the third party; (c) information which is in
     the restricted PARTY'S possession prior to the time of disclosure by the
     protected party and not acquired by the restricted party under a
     confidentiality obligation; or (d) information which enters the public
     domain without breach of confidentiality by the restricted party.

9.5  Other Information. The provisions of this Section 9 shall survive the
     termination of this Agreement and 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.

13.2 Dispute Resolution.

     13.2.1 Any dispute, controversy or claim arising out of or relating to this
          Agreement, or the interpretation, breach, termination or validity
          hereof, shall be resolved through consultation. Such consultation
          shall begin immediately after one party hereto has delivered to the
          other party hereto a written request for such consultation. If within
          thirty (30) days following the date on which such notice is given the
          dispute cannot be resolved, the dispute shall be submitted to
          arbitration upon the request of either party with notice to the other.

     13.2.2 The arbitration shall be conducted in Hong Kong under the auspices
          of the Hong Kong International Arbitration Centre (the "Centre").
          There shall be three arbitrators. Each party hereto shall each select
          one arbitrator within thirty (30) days after giving or receiving the
          demand for arbitration. Such arbitrators shall be freely selected, and
          the parties shall not be limited in their selection to any prescribed
          list. The Chairman of the Centre shall select the third arbitrator,
          who shall be qualified to practice law in New York. If either party
          does not appoint an arbitrator who has consented to participate within
          thirty (30) days after selection of the first arbitrator, the relevant
          appointment shall be made by the Chairman of the Centre.

     13.2.3 The arbitration proceedings shall be conducted in English. The
          arbitration tribunal shall apply the Arbitration Rules of the Center
          in effect at the time of the arbitration. However, if such rules are
          in conflict with the provisions of this Section 13.2, including the
          provisions concerning the appointment of arbitrators, the provisions
          of this Section 13.2 shall prevail.

     13.2.4 The arbitrators shall decide any dispute submitted by the parties to
          the arbitration strictly in accordance with the substantive law of New
          York and shall not apply any other substantive law.

     13.2.5 Each party hereto shall cooperate with the other in making full
          disclosure of and providing complete access to all information and
          documents requested by the other in connection with such arbitration
          proceedings, subject only to any confidentiality obligations binding
          on such party.

     13.2.6 The award of the arbitration tribunal shall be final and binding
          upon the disputing parties, and either party may apply to a court of
          competent jurisdiction for enforcement of such award.

     13.2.7 Either party shall be entitled to seek preliminary injunctive
          relief, if possible, from any court of competent jurisdiction pending
          the constitution of the arbitral tribunal.

     This Agreement may not be amended, modified or supplemented, except in a
     writing signed by each of the parties hereto.

15.  SUCCESSORS AND ASSIGNS

     parties hereto and their respective successors and assigns.
