so as to cover all of such Registrable Securities as soon as practicable, but in
any event not later than ten (10) Trading Days after the necessity therefor
arises. The Company shall use it reasonable best efforts to cause such amendment
and/or New Registration Statement to become effective as soon as practicable
following the filing thereof.

2

--------------------------------------------------------------------------------

 

     3.     RELATED OBLIGATIONS.

     With respect to the Registration Statement and whenever any Registrable
Securities are to be registered pursuant to Section 2(b) including on any New

effect the registration of the Registrable Securities in accordance with the
intended method of disposition thereof and, pursuant thereto, the Company shall
have the following obligations:

          a.     The Company shall prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to any registration
statement and the prospectus used in connection with such registration
statement, which prospectus is to be filed pursuant to Rule 424 promulgated
under the 1933 Act, as may be necessary to keep the Registration Statement or
any New Registration Statement effective at all times during the Registration
Period, and, during such period, comply with the provisions of the 1933 Act with
respect to the disposition of all Registrable Securities of the Company covered
by the Registration Statement or any New Registration Statement until such time
as all of such Registrable Securities shall have been disposed of in accordance
with the intended methods of disposition by the seller or sellers thereof as set
forth in such registration statement.

          b.     The Company shall permit the Investor to review and comment
upon the Registration Statement or any New Registration Statement and all
amendments and supplements thereto at least two (2) Trading Days prior to their
filing with the SEC, and not file any document in a form to which Investor
reasonably objects. The Investor shall use its reasonable best efforts to
comment upon the Registration Statement or any New Registration Statement and
any amendments or supplements thereto within two (2) Trading Days from the date
the Investor receives the final version thereof. The Company shall furnish to
the Investor, without charge any correspondence from the SEC or the staff of the
SEC to the Company or its representatives relating to the Registration Statement
or any New Registration Statement.

          c.     Upon request of the Investor, the Company shall furnish to the
Investor, (i) promptly after the same is prepared and filed with the SEC, at
least one copy of such registration statement and any amendment(s) thereto,
including financial statements and schedules, all documents incorporated therein
by reference and all exhibits, (ii) upon the effectiveness of any registration
statement, a copy of the prospectus included in such registration statement and
all amendments and supplements thereto (or such other number of copies as the
Investor may reasonably request) and (iii) such other documents, including
copies of any preliminary or final prospectus, as the Investor may reasonably
request from time to time in order to facilitate the disposition of the
Registrable Securities owned by the Investor.

          d.     The Company shall use reasonable best efforts to (i) register
and qualify the Registrable Securities covered by a registration statement under
such other securities or “blue sky” laws of such jurisdictions in the United
States as the Investor reasonably requests, (ii) prepare and file in those
jurisdictions, such amendments (including post-effective amendments) and
supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to (x) qualify to do business in any jurisdiction where it would not
otherwise be required to

3

--------------------------------------------------------------------------------

 

qualify but for this Section 3(d), (y) subject itself to general taxation in any
such jurisdiction, or (z) file a general consent to service of process in any
such jurisdiction. The Company shall promptly notify the Investor who holds
Registrable Securities of the receipt by the Company of any notification with
respect to the suspension of the registration or qualification of any of the
Registrable Securities for sale under the securities or “blue sky” laws of any
jurisdiction in the United States or its receipt of actual notice of the
initiation or threatening of any proceeding for such purpose.

          e.     As promptly as practicable after becoming aware of such event
or facts, the Company shall notify the Investor in writing of the happening of
any event or existence of such facts as a result of which the prospectus
included in any 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, in light of the
circumstances under which they were made, not misleading, and promptly prepare a
supplement or amendment to such registration statement to correct such untrue
statement or omission, and deliver a copy of such supplement or amendment to the
Investor (or such other number of copies as the Investor may reasonably
request). The Company shall also promptly notify the Investor in writing
(i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and when a registration statement or any post-effective
amendment has become effective (notification of such effectiveness shall be
delivered to the Investor by facsimile on the same day of such effectiveness and
by overnight mail), (ii) of any request by the SEC for amendments or supplements
to any registration statement or related prospectus or related information, and
(iii) of the Company’s reasonable determination that a post-effective amendment
to a registration statement would be appropriate.

          f.     The Company shall use its reasonable best efforts to prevent
the issuance of any stop order or other suspension of effectiveness of any
registration statement, or the suspension of the qualification of any
Registrable Securities for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify the Investor of the issuance of such
order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

          g.     The Company shall (i) cause all the Registrable Securities to
be listed on each securities exchange on which securities of the same class or
series issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation and quotation of all the Registrable Securities on the
Principal Market. The Company shall pay all fees and expenses in connection with
satisfying its obligation under this Section.

          h.     The Company shall cooperate with the Investor to facilitate the
timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to any
registration statement and enable such certificates to be in such denominations
or amounts as the Investor may reasonably request and registered in such names
as the Investor may request.

          i.     The Company shall at all times provide a transfer agent and
registrar with respect to its ADSs.

          j.     If reasonably requested by the Investor, the Company shall
(i) immediately incorporate in a prospectus supplement or post-effective
amendment such information as the Investor believes should be included therein
relating to the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being sold, the purchase price being paid therefor and any other
terms of the offering of the Registrable

4

--------------------------------------------------------------------------------

 

Securities; (ii) make all required filings of such prospectus supplement or
post-effective amendment as soon as notified of the matters to be incorporated
in such prospectus supplement or post-effective amendment; and (iii) supplement
or make amendments to any registration statement.

          k.     The Company shall use its reasonable best efforts to cause the
Registrable Securities covered by the any registration statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to consummate the disposition of such Registrable
Securities.

          l.     Within one (1) Trading Day after any registration statement
which includes the Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver,
to the transfer agent for such Registrable Securities (with copies to the
Investor) confirmation that such registration statement has been declared
effective by the SEC in the form attached hereto as Exhibit A. Thereafter, if
requested by the Buyer at any time, the Company shall require its counsel to
deliver to the Buyer a written confirmation whether or not the effectiveness of
such registration statement has lapsed at any time for any reason (including,
without limitation, the issuance of a stop order) and whether or not the
registration statement is current and available to the Buyer for sale of all of
the Registrable Securities.

          m.     The Company shall take all other reasonable actions necessary
to expedite and facilitate disposition by the Investor of Registrable Securities
pursuant to any registration statement.

     4.     OBLIGATIONS OF THE INVESTOR.

          a.     The Company shall notify the Investor in writing of the
information the Company reasonably requires from the Investor in connection with
any registration statement hereunder. The Investor shall furnish to the Company
such information regarding itself, the Registrable Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities
and shall execute such documents in connection with such registration as the
Company may reasonably request.

          b.     The Investor agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of any
registration statement hereunder.

          c.     The Investor agrees that, upon receipt of any notice from the
Company of the happening of any event or existence of facts of the kind
described in Section 3(f) or the first sentence of 3(e), the Investor will
immediately discontinue disposition of Registrable Securities pursuant to any
registration statement(s) covering such Registrable Securities until the
Investor’s receipt of the copies of the supplemented or amended prospectus
contemplated by Section 3(f) or the first sentence of 3(e). Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to promptly
deliver ADSs without any restrictive legend in accordance with the terms of the
Subscription Agreement in connection with any sale of Registrable Securities
with respect to which an Investor has entered into a contract for sale prior to
the Investor’s receipt of a notice from the Company of the happening of any
event of the kind described in Section 3(f) or the first sentence of 3(e) and
for which the Investor has not yet settled.

--------------------------------------------------------------------------------

 

     5.     EXPENSES OF REGISTRATION.

     All reasonable expenses, other than sales or brokerage commissions,
incurred in connection with registrations, filings or qualifications pursuant to
Sections 2 and 3, including, without limitation, all registration, listing and
qualifications fees, printers and accounting fees, and fees and disbursements of
counsel for the Company, shall be paid by the Company.

     6.     INDEMNIFICATION.

          a.     To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend the Investor, each Person, if
any, who controls the Investor, the members, the directors, officers, partners,
employees, agents, representatives of the Investor and each Person, if any, who
controls the Investor within the meaning of the 1933 Act or the Securities
Exchange Act of 1934, as amended (the “1934 Act”) (each, an “Indemnified
Person”), against any losses, claims, damages, liabilities, judgments, fines,
penalties, charges, costs, attorneys’ fees, amounts paid in settlement or
expenses, joint or several, (collectively, “Claims”) incurred in investigating,
preparing or defending any action, claim, suit, inquiry, proceeding,
investigation or appeal taken from the foregoing by or before any court or
governmental, administrative or other regulatory agency, body or the SEC,
whether pending or threatened, whether or not an indemnified party is or may be
a party thereto (“Indemnified Damages”), to which any of them may become subject
insofar as such Claims (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact in the Registration
Statement, any New Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the
offering under the securities or other “blue sky” laws of any jurisdiction in
which Registrable Securities are offered (“Blue Sky Filing”), or the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, (ii) any untrue
statement or alleged untrue statement of a material fact contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading, (iii) any violation or alleged violation by the Company of
the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable Securities pursuant to the Registration Statement or
any New Registration Statement or (iv) any material violation by the Company of
this Agreement (the matters in the foregoing clauses (i) through (iv) being,
collectively, “Violations”). The Company shall reimburse each Indemnified Person
promptly as such expenses are incurred and are due and payable, for any legal
fees or other reasonable expenses incurred by them in connection with
investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this
Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Company by such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement, any New Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) or Section 3(e); (ii) with respect to any superceded
prospectus, shall not inure to the benefit of any such person from whom the
person asserting any such Claim purchased the Registrable Securities that are
the subject thereof (or to the benefit of any person control ling such person)
if the untrue statement or omission of material fact contained in the superceded
prospectus was corrected in the revised prospectus, as then amended or
supplemented, if such revised prospectus was timely made

6

--------------------------------------------------------------------------------

 

available by the Company pursuant to Section 3(c) or Section 3(e), and the
Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a violation and such Indemnified
Person, notwithstanding such advice, used it; (iii) shall not be available to
the extent such Claim is based on a failure of the Investor to deliver or to
cause to be delivered the prospectus made available by the Company, if such
prospectus was timely made available by the Company pursuant to Section 3(c) or
Section 3(e); and (iv) shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of the
Company, which consent shall not be unreasonably withheld. Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Indemnified Person and shall survive the transfer of the
Registrable Securities by the Investor pursuant to Section 9.

          b.     In connection with the Registration Statement or any New
Registration Statement, the Investor agrees to severally and not jointly
indemnify, hold harmless and defend, to the same extent and in the same manner
as is set forth in Section 6(a), the Company, each of its directors, each of its
officers who signs the Registration Statement or any New Registration Statement,
each Person, if any, who controls the Company within the meaning of the 1933 Act
or the 1934 Act (collectively and together with an Indemnified Person, an
“Indemnified Party”), against any Claim or Indemnified Damages to which any of
them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar
as such Claim or Indemnified Damages 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
about the Investor set forth on Exhibit B attached hereto and furnished to the
Company by the Investor expressly for use in connection with such registration
statement; and, subject to Section 6(d), the Investor will reimburse any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such Claim; provided, however, that the indemnity agreement
contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of the
Investor, which consent shall not be unreasonably withheld; provided, further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to
the Investor as a result of the sale of Registrable Securities pursuant to such
registration statement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investor
pursuant to Section 9.

          c.     Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
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 control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying party, if, in
the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. The Indemnified
Party or Indemnified Person shall cooperate fully with the indemnifying party in
connection with any negotiation or defense of

7

--------------------------------------------------------------------------------

 

any such action or claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified Party
or Indemnified Person which relates to such action or claim. The indemnifying
party shall keep the Indemnified Party or Indemnified Person fully apprised at
all times as to the status of the defense or any settlement negotiations with
respect thereto. No indemnifying party shall be liable for any settlement of any
action, claim or proceeding effected without its written consent, provided,
however, that the indemnifying party shall not unreasonably withhold, delay or
condition its consent. No indemnifying party shall, without the consent of the
Indemnified Party or Indemnified Person, consent to entry of any judgment or
enter into any settlement or other compromise which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party or Indemnified Person of a release from all liability in
respect to such claim or litigation. Following indemnification as provided for
hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.

          d.     The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

          e.     The indemnity agreements contained herein shall be in addition
to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

     7.     CONTRIBUTION.

          To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities.

     8.     REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS.

          With a view to making available to the Investor the benefits of
Rule 144 promulgated under the 1933 Act or any other similar rule or regulation
of the SEC that may at any time permit the Investor to sell securities of the
Company to the public without registration (“Rule 144”), the Company agrees, at
the Company’s sole expense, to:

          a.     make and keep public information available, as those terms are
understood and defined in Rule 144;

8

--------------------------------------------------------------------------------

 

           b.     file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements and the filing of such reports
and other documents is required for the applicable provisions of Rule 144; and

     c.     furnish to the Investor so long as the Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting and or disclosure provisions of Rule 144, the
1933 Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested to
permit the Investor to sell such securities pursuant to Rule 144 without
registration.

     d.     take such additional action as is requested by the Investor to
enable the Investor to sell the Registrable Securities pursuant to Rule 144,
including, without limitation, delivering all such legal opinions, consents,
certificates, resolutions and instructions to the Company’s Transfer Agent as
may be requested from time to time by the Investor and otherwise fully cooperate
with Investor and Investor’s broker to effect such sale of securities pursuant
to Rule 144.

The Company agrees that damages may be an inadequate remedy for any breach of
the terms and provisions of this Section 8 and that Investor shall, whether or
not it is pursuing any remedies at law, be entitled to equitable relief in the
form of a preliminary or permanent injunctions, without having to post any bond
or other security, upon any breach or threatened breach of any such terms or
provisions.

     9.     ASSIGNMENT OF REGISTRATION RIGHTS.

          The Company shall not assign this Agreement or any rights or
obligations hereunder without the prior written consent of the Investor,
including by merger or consolidation. The Investor may not assign its rights
under this Agreement without the written consent of the Company, other than to
an affiliate of the Investor or, upon prior notice to the Company in writing, in
connection with a private transfer or sale of Registrable Securities made
pursuant to an exemption from registration under the 1933 Act (other than
Rule 144 thereunder) and in compliance with this Agreement and the Subscription
Agreement.

     10.     AMENDMENT OF REGISTRATION RIGHTS.

     Provisions of 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 with the written consent of the Company and the
Investor.

     11.     MISCELLANEOUS.

          a.     A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more Persons with respect to the same Registrable
Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.
