(c) In the event that, in the reasonable judgment of the Company, it is advisable to suspend use of a Registration Statement or Prospectus therein due to pending material developments or other events that have not yet been publicly disclosed and as to which the Company reasonably believes public disclosure thereof would be detrimental to the Company, the Company shall notify all of the Holders in writing to such effect, and, upon receipt of such notice, the Holders shall immediately discontinue any sales of Registrable Securities pursuant to such Registration Statement or Prospectus until the Holders have received copies of a supplemented or amended Prospectus or until the Holders are advised in writing by the Company that the then current Prospectus may be used and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus, provided, that the Company shall use commercially reasonable efforts to ensure that such suspension by the Company shall be terminated and the use of the Prospectus (as supplemented, amended by the Company) may be resumed as soon as practicable but in any event any suspension by the Company pursuant to the immediately foregoing clause with respect to any single development or event or a series of related developments or events shall not be more than twenty (20) days in the aggregate.

(d) Notwithstanding anything in this Agreement to the contrary, so long as the Registration Statement is on Form F-1 or on any other form that does not allow for forward incorporation by reference of reports and other materials filed by the Company pursuant to Section 13(a) or 15(d) of the Exchange Act, the Company may suspend sales under such Registration Statement as follows: (i) for the period commencing at the time that the Company disseminates a press release announcing its preliminary financial results for any fiscal period and ending on the third (3rd) Business Day after the earlier of (A) the date that the related report on Form 20-F under the Exchange Act is filed with the SEC and (B) the date on which such report is required to be filed under the Exchange Act (giving effect to Rule 12b-25 promulgated thereunder); (ii) for the period commencing at the time that the Company disseminates a press release announcing a material development that would make a statement of a material fact in such Registration Statement untrue or misleading and ending on the third (3rd) Business Day after the earlier of (A) the date that the related report on Form 6-K is filed with the SEC and (B) the date on which such report is required to be filed under the Exchange Act (giving effect to Rule 12b-25 promulgated thereunder); (iii) to the extent necessary to allow any post-effective amendment to the Registration Statement or supplement to the prospectus to be prepared and, if necessary, filed with the SEC and, in the case of a post-effective amendment, declared effective; and (iv) for a period during which the Company, in the good faith opinion of the board of directors of the Company, determines that the disclosure of material, non-public information concerning the Company or any of its subsidiaries would be materially detrimental to the Company; provided, that the Company shall promptly notify the Holders in writing (I) of the existence of such material, non-public information (provided, that in each notice the Company will not disclose the content of such material, non-public information to the Holders) and the date on which such suspension will begin and (II) of the date on which such suspension ends.

3. Piggyback Registrations.

(a) If the Company proposes to file a Registration Statement under the Securities Act for its own account or the account of others (other than the Holders) under the Securities Act of any of its Equity Securities (including Registration Statements relating to

5

secondary offerings of securities of the Company, but excluding Registration Statements relating to (i) any employee benefit plan or (ii) a corporate reorganization, merger or acquisition), then the Company shall notify all Holders in writing at least thirty (30) calendar days prior to such filing and will 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 wishing to include in any such Registration Statement all or any part of the Registrable Securities held by such Holder shall, within twenty (20) calendar 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 on the same terms and conditions as the Equity Securities of the Company included therein. If a Holder decides not to include all or any portion of its Registrable Securities in any Registration Statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include its Registrable Securities in any subsequent Registration Statement that may be filed by the Company with respect to offerings of its securities for its own account or for the account of another (other than the Holders), all upon the terms and conditions set forth herein.

(b) If a Registration Statement under which the Company gives notice under this Section 3 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities in the same notice that the Company is required to deliver to the Holders pursuant to Section 3(a). In such an event, the right of any Holder to include its Registrable Securities in a Registration pursuant to this Section 3 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 underwriter(s) selected by the Company 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 (including Registrable Securities) from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated: (1) first, the Equity Securities the Company proposes to sell for its own account, (2) second, the Registrable Securities requested by the Holders to be included in such Registration, pro rata among the Holders requesting inclusion in such Registration on the basis of the number of securities requested to be included by all such Holders, and (3) third, any other Equity Securities of the Company requested to be included.

(c) With respect to a Registration Statement initiated by the Company for its own account, the Company shall have the right to terminate or withdraw such registration at any time prior to the effectiveness of the Registration Statement, whether or not any Holder has elected to include Registrable Securities in such registration.

(d) The Company hereby represents and warrants that, except as contemplated under this Agreement and the Purchase Agreement, neither the Company nor any of its Affiliates has granted or agreed to grant to any Person any registration rights (including, without limitation, demand and piggyback registration rights) with respect to, and neither the Company nor any of its Affiliates is a party to, or is otherwise bound by, any agreement (whether oral or in writing) that requires the Company or any of its Affiliates to register under the Securities Act or the securities laws of any state or any other jurisdiction and/or list on any securities exchange, any Equity Securities of the Company or of any Affiliate of the Company.

(b) prepare and file with the SEC such amendments and supplements to such Registration Statement and the Prospectus used in connection with such Registration Statement as may be necessary to comply with the applicable requirements of the Securities Act and to keep such Registration Statement or any successor Registration Statement as described in clause (a) effective until the expiration of the Effective Period or, if applicable, the date of the early termination of the Registration Rights pursuant to Section 4 hereof, and to comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by such Registration Statement;

(c) furnish to the Holders such number of copies of the Prospectus included in such Registration Statement (including each preliminary Prospectus) and any amendment thereof or supplement thereto (in each case including all exhibits and materials incorporated by reference therein), each in conformity with the requirements of the Securities Act, and such other documents as such Holders may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such Registration Statement;

(d) notify in writing the Holders and their counsel (i) of the receipt by the Company of any notification with respect to any comments by the SEC with respect to such Registration Statement or Prospectus or any amendment thereof or supplement thereto or any request by the SEC for the amending thereof or supplementing thereof or for additional information with respect thereto, (ii) of the receipt by the Company of any notification with respect to the issuance by the SEC of any stop order suspending the effectiveness of such Registration Statement or Prospectus or any amendments thereof or supplements thereto or the

(e) use its commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of the Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment;

(f) use its commercially reasonable efforts to Register and qualify the securities covered by such registration statement under such other securities Laws or “blue sky” laws of such jurisdictions as shall be reasonably requested by the Holders and do any and all other acts and things that may be reasonably necessary or advise to enable such Holders to consummate the disposition and/or distribution of the Registrable Securities then held by such Holders in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 6(f) or to file a general consent to service of process in any such jurisdictions where the Company would not otherwise be required to do so but for this Section 5(f);

(h) immediately notify each Holder of Registrable Securities covered by such Registration Statement, at any time prior to the end of the Effective Period, or, if applicable, the date of the early termination of the Registration Rights pursuant to Section 4 hereof, upon discovery that, or upon the happening of any event as a result of which, the Prospectus 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, and promptly prepare, file with the SEC and furnish to such Holder a supplement to or an amendment of such Prospectus as may be necessary so that such Prospectus shall not include any untrue statement of a material fact or omit 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;

(i) furnish, at the request of any Holder requesting Registration of Registrable Securities, on the date that such Registrable Securities are delivered to the underwriters 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 Registrable Securities becomes effective, (i) an opinion, dated as of such date, of the outside 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 of Registrable Securities Then

In connection therewith, if required by the Company’s agent which maintains the register of members of Ordinary Shares or the Depositary, the Company shall promptly after the effectiveness of the Registration Statement cause an opinion of legal counsel as to the effectiveness of the Registration Statement to be delivered to such agent or the Depositary, together with any other authorizations, certificates and directions requested by such agent or the Depositary, which authorize and direct such agent or the Depositary to issue such Registrable Securities without legend upon disposition by the Holders under the Registration Statement; and

Depositary, or any successor which administers the Company’s ADS program, imposes any fees or expenses on any Holder in connection with the deposit by such Holder of its Registrable Securities in exchange for ADSs made by such Holder for any reason, the Company shall pay all such fees and expenses.

9. Indemnification.

(a) By the Company. The Company shall indemnify and hold harmless each Holder, its officers, directors, employees, members, partners, and advisors and their respective Affiliates, each underwriter, broker or any other Person acting on behalf of such Holder and each other Person, if any, who controls any of the foregoing Persons within the meaning of the Securities Act or the Exchange Act against all losses, claims, damages, liabilities, or actions joint or several (or actions in respect thereof), to which any of the foregoing Persons may become subject under the Securities Act, the Exchange Act or other federal or state securities 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) any 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 Exchange Act, any federal or state securities Law or any rule or regulation promulgated under the Securities Act, the Exchange 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, officer, director, employee, member, partner, and advisor and their respective Affiliates, each underwriter, broker or any other Person acting on behalf of such Holder or controlling Person for any legal or other expenses reasonably incurred by them in connection with defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 10(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 written 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 any such foregoing Person.

(b) By the Selling Holders. Each selling Holder shall, severally and not jointly, indemnify and hold harmless the Company, each of its directors, officers who have signed the registration statement and advisors and each of their respective Affiliates, each underwriter, broker, and each other Person, if any, who controls any of the foregoing Persons within the meaning of the Securities Act or the Exchange Act, against all losses, claims, damages or liabilities (joint or several) to which the Company or any such foregoing Person may become subject under the Securities Act, the Exchange Act or other federal or state law, 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 under an instrument duly executed by such Holder and stated to be expressly for use in connection with

10

such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such foregoing Person in connection with defending any such loss, claim, damage, liability or action; provided, however, the indemnity agreement contained in this Section 10(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Holder (which consent shall not be unreasonably withheld); provided, further, the total amounts payable in indemnity by a Holder under this Section 9(b) and Section 9(d) in respect of any Violation shall not exceed the net proceeds actually received by such Holder upon the sale of the Registrable Securities out of which such Violation arises.

(c) Notice. Promptly after receipt by an indemnified party under this Section 10 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 10, 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, 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, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 10.

(d) Contribution. If the indemnification provided for in this Section 10 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable Law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability 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 Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, in no event shall any contribution by a Holder hereunder, when combined with the amounts paid or payable by such Holder pursuant to Section 9(b) hereof, exceed the net proceeds actually received by such Holder upon the sale of the Registrable Securities out of which such Violation arises.

(e) Survival. The obligations of the Company and Holders under this Section 10 shall survive the completion of any offering of Registrable Securities in a registration statement, and otherwise.

11

10. Rule 144 Reporting.

With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the SEC which may at any time permit the Holders to sell Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts 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) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and
