For purposes hereof, the term “Effective Time” means the earlier of (i) the expiration of the twelve (12) month period following the date of the Qualified IPO and (ii) the eighteen (18) month anniversary of the Closing Date.

5.2 Right of First Refusal

5.2.1 Without prejudice to Clause 5.1, every Shareholder (other than an Investor) who desires to transfer any Share or Shares (the “Transferor”) other than in connection with a Permitted Transfer (as defined below) shall give to the Company and the Shareholders other than the Transferor (the “Other Shareholders”) a notice in writing of such desire (a “Transfer Notice”), which notice shall specify:

(a) the identity of the buyer to whom the Transferor proposes to transfer such shares (the “Buyer”);

(b) the number of Shares proposed to be transferred (the “Sale Shares”);

(d) the other terms and conditions of such sale (if any) (the “Prescribed Terms”).

5.2.2 Subject as hereinafter mentioned, a Transfer Notice shall first constitute an offer by the Transferor for the sale of the Sale Shares to the Company at the Transferor’s Price and on the Prescribed Terms (if any) in the order of preference as described in the provisions below. Subject to Clause 5.2.7 below, a Transfer Notice shall not be revocable except with the sanction of the Board.

5.2.3 Upon its receipt of the Transfer Notice, and within thirty (30) days of the date of dispatch of the notice (the “First Refusal Period”), the Company shall have the option to purchase the Sale Shares (being all or any thereof).

5.2.4 Subject to Clause 5.2.3 above, upon the exercise of the Company’s option to purchase the Sale Shares in accordance with Clause 5.2.3 above, the Transferor shall be bound to transfer the Sale Shares to the Company at the time and place specified by the

Company by the delivery of duly executed transfer forms together with the share certificates in respect of such Sale Shares and, if it shall fail to do so, a person appointed by the Board shall be deemed to have been appointed attorney of the Transferor with full power to execute, complete and deliver, in the name and on behalf of the Transferor, transfers of the Sale Shares to the Company against payment of the price to the Transferor.

5.2.5 Within ten (10) days after expiration of the First Refusal Period, the Transferor will give written notice to the Other Shareholders specifying either (i) that all of the Sale Shares have been subscribed by the Company; or (ii) that the Company has not subscribed all of the Offered Shares. Each of the Other Shareholder will have the right, exercisable upon written notice to the Transferor and each Other Shareholder within thirty (30) days after the expiration of the First Refusal Period (the “Second Refusal Period”) of its election to exercise its right of refusal hereunder.

5.2.6 Each Other Shareholder will have the right to purchase that number of remaining Sale Shares (the “Second Refusal Allotment”) equivalent to the product obtained by multiplying the aggregate remaining number of the Sale Shares by a fraction, the numerator of which is the number of Ordinary Shares held by such Other Shareholder (on an as-converted basis) at the time of the transaction and the denominator of which is the total number of Ordinary Shares owned by all the Other Shareholders (on an as-converted basis) at the time of the transaction. Any Other Shareholder will not have a right to purchase any of the Sale Shares unless it exercises its right of refusal within the Second Refusal Period to purchase up to all of its Second Refusal Allotment of the remaining Sale Shares. To the extent that any other Shareholder does not exercise its right of refusal to the full extent of its Second Refusal Allotment, the Transferor and the Other Shareholders shall, within five (5) days after the end of the Second Refusal Period, make such adjustments to the Second Refusal Allotment of each exercising Other Shareholder so that any remaining Sale Shares may be allocated to those Other Shareholders exercising their rights of first refusal on a pro rata basis.

5.2.7 During the two (2) months following the expiry of the Second Refusal Period, the Transferor shall be at liberty to transfer any Sale Share acquired at the Closing not purchased by the Company or the Other Shareholders to the Buyer and at any price (not being less than the Transferor’s Price) and on terms not more favourable than the Prescribed Terms (if any) except that the Transferor may provide representations, warranties, covenants and indemnities customary for such transfer to the Buyer.

5.3 Co-Sale Right

5.3.1 Tag-Along Rights: Subject to the provisions herein, if at any time any Shareholder other than an Investor (“Tag-Along Transferor”) desires to sell or transfer (“Transfer”) its Shares to a Buyer or any third party other than in connection with a Permitted Transfer, each other Shareholder shall, after its exhaustion of their rights of first refusal under Clause 5.2, be entitled to exercise tag-along rights in accordance with the following procedure:

(a) the Tag-Along Transferor shall notify each other Shareholder in writing, of such proposed Transfer, and of the terms and conditions of the proposed Transfer, including the price per Share at which the Transferor proposes to Transfer such Shares (“Transfer Price”);

(b) within fourteen (14) Business Days of the date of such notice, each other Shareholder shall notify the Tag-Along Transferor (a “Tag-Along Notice”) if it wishes to include its Shares in the proposed Transfer. If any other Shareholder fails to do so, that Shareholder shall be deemed to have waived its rights under this Clause in respect of such Transfer;

(c) if any other Shareholder (a “Participating Selling Shareholder”) so notifies the Tag-Along Transferor, that Shareholder shall have the right to include such number of its Shares specified in the Tag-Along Notice in the proposed Transfer at a price per Share equal to the Transfer Price (in the case where the shares are of the same series as the Tag-Along Transferor’s shares) or at a price per Share on a deemed converted basis equal to the equivalent transfer price (in the case where the shares are of a different series from the Tag-Along Transferor’s shares) and on the same terms and conditions as those applicable to the Tag-Along Transferor. The maximum number of Shares a Shareholder can include in the proposed Transfer is limited to, or if the Shareholder fails to specify the number of Shares in the Tag-Along Notice, then the number of Shares deemed specified in the Tag-Along Notice shall be, a pro rata portion of its Shares which is determined by multiplying (1) the number of Shares specified in the Tag-Along Notice by (2) a fraction where the numerator is the number of Ordinary Shares (on an as-if converted basis) of which that Participating Selling Shareholder is the registered holder of, or in respect of which it is unconditionally entitled to be registered as the holder of, and the denominator is the sum of all Ordinary Shares (on an as-if converted basis) of which the Tag-Along Transferor and all the Participating Selling Shareholders participating in such tag-along are registered or unconditionally entitled to be registered as holders of; and

(d) the Tag-Along Transferor shall procure that such Transfer be effected and the number of Shares the Tag-Along Transferor may actually Transfer shall be reduced by the lesser of (1) the number of Shares specified in the Tag-Along Notice and (2) the number of pro rata Shares determined pursuant to Clause 5.3.1(c).

5.4 Right of First Offer

5.4.1 Subject to Clause 5.5, any Investor (an “Offering Holder”) who desires to transfer any Share or Shares (the “Offered Shares”) shall give to the Company and the other Shareholders (the “Non-Transferring Shareholders”) a notice in writing of such desire (an “Offering Notice”), which notice shall include a description of the Offered Shares, including, without limitation, the number of Shares to be sold or transferred.

5.4.2 Each of the Company and the Non-Transferring Shareholders shall have a right, within thirty (30) days after delivery of the Offering Notice, to make an offer in writing (a “Purchase Offer”) to purchase all, but not less than all, of the Offered Shares. Any Purchase Offer shall set forth the consideration and the material terms and conditions upon which the party making the Purchase Offer proposes to acquire the Offered Shares. Within fifteen (15) days of receiving a timely Purchase Offer, the Offering Holder shall accept or decline the Purchase Offer in writing, and prior to expiration of such 15-day period, the Purchase Offer shall not be rescinded.

5.4.3 If the Offering Holder shall accept a Purchase Offer, then the Offering Holder and the party making such Purchase Offer shall use their good faith efforts to conclude, within ninety (90) days after the date of the Offering Notice, a sale between them of the Offered Shares pursuant to the terms and conditions of the Purchase Offer. If the Offering Holder and the party making the Purchase Offer have not timely concluded the sale of the Offered Shares within such 90 day period, the Purchase Offer shall be deemed to have been rescinded, and neither the party making such Purchase Offer or the Offering Holder shall have any further obligation to consummate a sale of the Offered Shares pursuant to the terms and conditions of such Purchase Offer.

5.4.4 In respect of any Offering Notice for Offered Shares, following the Release (as defined below) of such Offered Shares from the right of first offer contained in this Clause 5.4, the Offering Holder may either withdraw its intention to sell the Offered Shares or, for a period of 120 days from the date of the Release, the Offering Holder shall have the right to conclude a binding sale and purchase agreement with a third party to purchase the Offered Shares; provided that the terms and conditions of any sale of the Offered Shares to a third party including, without limitation, the consideration for such sale shall be more favourable to the Offering Holder than the terms and conditions contained in any timely Purchase Offer. If the Offering Holder has not concluded a binding sale and purchase agreement for the Offered Shares within such 120-day period, the Offering Holder shall not further be entitled to enter into a binding agreement to transfer the Offered Shares to any third party without first again permitting the other parties hereto to exercise their right of first offer under this Clause 5.4. In respect of any Offering Notice for Offered Shares, “Release” shall mean the earlier of (i) the date that the 30-day period for making Purchase Offers hereunder shall expire without the Offering Holder having received a Purchase Offer, (ii) the date that the Offering Holder shall have declined to accept all timely Purchase Offers, or (iii) the date that any Purchase Offer accepted by the Offering Holder may subsequently be rescinded pursuant to Clause 5.4.3.

(c) Notwithstanding anything to the contrary in this Agreement, any transfer of Shares pursuant to this Clause 5.5.1 shall not relieve or discharge the Transferor Corporation from any of its obligations under this Agreement and the Transferor Corporation shall continue to be subject to the obligations under this Agreement and be liable to the other Parties as if no such transfer had occurred and the liability of the Transferor Corporation hereunder shall be joint and several with its Affiliate or Affiliated Entity which holds those Shares pursuant to any transfer under this Clause 5.5.1, provided however that this provision shall cease to apply upon the disposal and transfer by that transferee of all the relevant Shares as permitted under this Agreement other than by a transfer or re-transfer pursuant to the provisions of this Clause 5.5.1.

(d) For any transferor that is, directly or indirectly, a fund, any transfer of Shares to such fund’s limited partners is permitted, so long as such limited partners appoint the same agent to represent such limited partners in connection with this Agreement.

5.5.2 Additional Permitted Transfers. Notwithstanding the foregoing or anything to the contrary herein, the provisions of Clauses 5.1, 5.2 and 5.3 shall not apply in the case of a Shareholder that is a natural person, upon a transfer of Shares by such Shareholder made for bona fide estate planning purposes (a “Permitted Transfer”), either during his or her lifetime or on death by will or intestacy to his or her spouse, child (natural or adopted), or any other direct lineal descendant of such Shareholder (or his or her spouse) (all of the foregoing collectively referred to as “family members”), or any other relative/person approved by the unanimous consent of the Board of Directors of the Company, or any custodian or trustee of any trust, partnership or limited liability company for the benefit of, or the ownership interests of which are owned wholly by, such Shareholder or any such family members, provided that such Shareholder shall deliver prior written notice to the Investors of such transfer and such Shares shall at all times remain subject to the terms and restrictions set forth in this Agreement and such transferee shall, as a condition to such issuance, deliver a counterpart signature page to this Agreement

as confirmation that such transferee shall be bound by all the terms and conditions of this Agreement as a Shareholder (but only with respect to the securities so transferred to the transferee); and provided, further, that such transfer is made pursuant to a transaction in which there is no consideration actually paid for such transfer.

8. REGISTRATION RIGHTS

8.1 Demand Registration

8.1.1 Subject to the conditions of this Clause 8.1, if the Company shall receive at any time after the earlier of (i) December 30, 2008, (ii) six (6) months after the effective date a Qualified IPO and (iii) the delivery of a Written Indication (as defined below), a written request from the Holders of at least twenty five percent (25%) of the Registrable Securities then outstanding (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities for which the reasonably anticipated aggregate price to the public, net of selling expenses, would exceed US$5,000,000, then the Company shall, within thirty (30) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Clause 8.1, use its commercially reasonable efforts to file and have declared effective, as soon as practicable, the registration under the Securities Act of all Registrable Securities that the Initiating

Holders, together with any Registrable Securities of any Holder who requests in writing to join such registration within fifteen days after the Company’s delivery of written notice, request to be registered. For purposes hereof, the term “Written Indication” means a written indication delivered to the Company by an internationally recognized investment banking institution other than Xxxxxxx Xxxxx (Asia) L.L.C. or any of its Affiliates (an “Independent Underwriter”) at the request of an Initiating Holder, that market conditions exist for the successful consummation of a Qualified IPO and that such Independent Underwriter would agree to underwrite, on a firmly underwritten basis, an offering of the Company’s equity securities that would constitute a Qualified IPO.

8.1.2 If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Clause 8.1 or any request pursuant to Clause 8.3 and the Company shall include such information in the written notice referred to in Clause 8.1.1 or Clause 8.3.1, as applicable. 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 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 Company. Notwithstanding any other provision of this Clause 8.1 or 8.3, if the underwriter advises the Company that marketing factors require a limitation of the number of securities to be underwritten (including Registrable Securities) then the Company shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated among such, including the Initiating Holders, on a pro rata basis based on the number of Registrable Securities held by all such Holders; provided however, that in no event shall any Registrable Securities then held by a Preferred Shareholder be excluded from such underwriting unless all other securities are first excluded. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration.

8.1.3 The Company shall not be required to file a registration pursuant to this Clause 8.1:

(a) after the Company has effected four registrations pursuant to this Clause 8.1, and such registrations have been declared or ordered effective;

(b) if the Company has effected a registration pursuant to this Clause 8.1 within the preceding twelve (12) months, and such registration has been declared effective;

(c) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred eighty (180) days following the effective date of, a Company-initiated

registration, provided that the Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective;

(d) if the Initiating Holders propose to dispose of Registrable Securities that may be immediately registered on Form F-3 pursuant to a request made pursuant to Clause 8.3 below; or

(e) if the Company shall furnish to Holders requesting a registration statement pursuant to this Clause 8.1, a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board, it would be seriously detrimental to the Company and its Shareholders for such registration statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than 90 days after receipt of the request of the Initiating Holders; provided that such right to delay a request pursuant to this Clause or Clause 8.3.1(b)(iv) shall be exercised by the Company not more than once in any twelve (12) month period.

8.2 Piggyback Registrations

8.2.1 The Company shall notify all Holders of Registrable Securities in writing at least thirty (30) days prior to the filing of any registration statement under the Securities Act for purposes of 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 employee benefit plans or with respect to corporate reorganizations or other transactions under Rule 145 of the Securities Act) and will afford each such Holder an opportunity to include in such registration statement all or part of such Registrable Securities 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 thirty (30) days after the above-described notice from the Company, so notify the Company in writing. Such notice shall state the intended method of disposition of the Registrable Securities by such Holder. 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. Upon the written request of each Holder given within twenty (20) days after mailing of such notice by the Company, the Company shall use commercially reasonable efforts to cause to be registered under the Act all of the Registrable Securities that each such Holder has requested to be registered.

8.2.2 If the registration statement in respect of which the Company gives notice under this Clause 8.2 is for an underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to be included in a registration pursuant to this Clause 8.2 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 in this Clause 8.2.2. All Holders

proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of the Agreement, if the underwriter determines in good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro rata basis based on the total number of Registrable Securities held by the Holders; and third, to any shareholder of the Company (other than a Holder) on a pro rata basis. In no event will shares of any other selling shareholder be included in such registration which would reduce the number of shares which may be included by Holders without the written consent of Holders of at least twenty five percent (25%) of the Registrable Securities proposed to be sold in the offering. 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, 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.

8.2.3 The Company shall have the right to terminate or withdraw any registration initiated by it under this Clause 8.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The expenses of such withdrawn registration shall be borne by the Company in accordance with Clause 8.4 hereof.

8.3 Form S-3 or F-3 Registration

8.3.1 In case the Company shall receive from any Holder or Holders of Registrable Securities then outstanding a written request or requests that the Company effect a registration on Form S-3 or Form F-3 (or any successor to Form S-3 or Form F-3), as applicable, or any similar short-form registration statement and any related qualification or compliance, for the public offering of Registrable Securities for which the reasonably anticipated aggregate price to the public, net of selling expenses, would exceed US$5,000,000, the Company will:

(a) promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders of Registrable Securities; and

(b) use commercially reasonable efforts, as soon as practicable, to 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 Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder as such other Holder seeks to include in the registration by giving written notice to the Company within thirty (30) days after receipt of the Company’s written notice; provided, however, that the Company shall not be

obligated to effect any such registration, qualification or compliance pursuant to this Clause 8.3:

(i) if Form S-3 or Form F-3 (or any successor or similar form) is not available for such offering by the Holders;

(ii) if within thirty (30) days of receipt of a written request from any Holder or Holders pursuant to this Clause 8.3, the Company gives notice to such Holder or Holders of the Company’s intention to make a public offering within ninety (90) days, provided, that such right to delay a request shall be exercised by the Company not more than once in any twelve (12) month period;

(iii) if the Company shall furnish to the Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board, it would be seriously detrimental to the Company and its shareholders for such Form S-3 or Form F-3 registration 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 for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Clause 8.3; provided, that such right to delay a request pursuant to this Clause 8.3 and Clause 8.1.3(d) shall be exercised by the Company not more than once in any twelve (12) month period;

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

(v) more than two in any twelve-month period.

8.3.2 Subject to the foregoing, the Company shall use commercially reasonable efforts to file a Form S-3 or Form F-3 registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. Registrations effected pursuant to this Clause 8.3 shall not be counted registrations effected pursuant to Clauses 8.1.

8.4 Expenses of Registration

All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Clauses 8.1 and 8.2, including, without limitation, all registration, filing and qualification fees (including “blue sky” fees), printers’ and accounting fees, fees and disbursements of counsel for the Company (including fees and disbursements of counsel for the Company in its capacity as counsel to the selling Holders hereunder; if Company counsel does not make itself available for this purpose, the Company will pay the reasonable fees and disbursements of one counsel for the selling Holders) shall be borne by the Company. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Clause 8.1 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the

Registrable Securities to be registered (in which case all participating Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be registered in the withdrawn registration).

8.5 Obligations of the Company

Whenever required to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

8.5.1 prepare and file with the United States Securities and Exchange Commission or other applicable securities regulatory agency (the “SEC”) a registration statement with respect to such Registrable Securities and use all reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to 180 days or, if earlier, until the Holder or Holders have completed the distribution related thereto; provided, however, that at any time, upon written notice to the participating Holders and for a period not to exceed sixty (60) days thereafter (the “Suspension Period”), the Company may delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration statement (and the Initiating Holders hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement during the Suspension Period) if the Company reasonably believes that there is or may be in existence material nonpublic information or events involving the Company, the failure of which to be disclosed in the prospectus included in the registration statement could result in a Violation (as defined below). In the event that the Company shall exercise its right to delay or suspend the filing or effectiveness of a registration hereunder, the applicable time period during which the registration statement is to remain effective shall be extended by a period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional consecutive sixty (60) days with the consent of the holders of a majority of the Registrable Securities registered or to be registered under the applicable registration statement, which consent shall not be unreasonably withheld. No more than two (2) such Suspension Periods shall occur in any twelve (12) month period. If so directed by the Company, all Holders registering shares under such registration statement shall (i) not offer to sell any Registrable Securities pursuant to the registration statement during the Suspension Period after receiving notice of such delay or suspension; and (ii) use their best efforts to deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holders’ possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. The Company shall use its commercially reasonable best efforts to promptly resolve any Violation resulting in a Suspension Period and to permit the filing and/or effectiveness of the applicable registration statement.

8.5.2 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 provisions of the Securities Act with respect to

the disposition of all securities covered by such registration statement for the period set forth in Clause 8.5.1 above.

8.5.3 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 Registrable Securities owned by them.

8.5.4 Use its commercially reasonable 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.

8.5.5 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.

8.5.6 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. The Company will use reasonable efforts to amend or supplement such prospectus in order to cause such prospectus not to 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.

8.5.7 Provide a transfer agent and registrar for all Registrable Securities registered pursuant to the registration statement and, where applicable, a CUSIP number for all those Registrable Securities, in each case not later than the effective date of the registration.

8.5.8 Use its reasonable efforts to furnish, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (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, addressed to the underwriters, if any, and (ii) a 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 underwritten public offering addressed to the underwriters.

8.5.9 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

initial public offering, the primary exchange upon which the Company’s securities will be traded.

8.6 Furnish Information

It shall be a condition precedent to the obligations of the Company to take any action pursuant to Clause 8.5 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 reasonably required to effect the registration of such Holder’s Registrable Securities.

8.7 Indemnification

In the event any Registrable Securities are included in a registration statement under Clauses 8.1, 8.2 or 8.3:

8.7.1 To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers, directors legal counsel and accountants of each Holder, any underwriter (as defined 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 “Exchange Act”), against any losses, claims, damages, or liabilities (joint or several) to which they 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 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 or incorporated reference therein, 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 Exchange Act, any other federal or state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any other federal or state securities law in connection with the offering covered by such registration statement; and the Company will reimburse each such Holder, partner, member, officer, director, legal counsel, accountant, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided however, that the indemnity agreement contained in this Clause 8.7.1 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 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.

8.7.2 To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, its directors, officers, legal counsel and accountants and each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors, officers, legal counsel or accountants or any person who controls such Holder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law or any rule or regulation promulgated thereunder, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any of the following statements: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, or (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 (collectively, a “Holder Violation”), in each case to the extent (and only to the extent) that such Holder 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 specifically for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, legal counsel, accountant, controlling person, underwriter or other Holder, or partner, officer, director, legal counsel, accountant or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that the indemnity agreement contained in this Clause 8.7.2 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.

8.7.3 Promptly after receipt by an indemnified party under this Clause 8.7 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 Clause 8.7, 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 reasonable 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 materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Clause 8.7, but the omission so 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 Clause 8.7.

8.7.4 If the indemnification provided for in this Clause 8.7 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages, liabilities or expenses 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, liability 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 Violation(s) or Holder Violation(s) that resulted in such loss, claim, damage, liability 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 a court of law 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.

8.7.5 The obligations of the Company and Holders under this Clause 8.7 shall survive completion of any offering of Registrable Securities in a registration statement and the termination of this Agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

8.8 “Market Stand-Off” Agreement

Each Holder hereby agrees that such Holder shall not sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Ordinary Shares (or other securities) of the Company held by such Holder (other than those included in the registration) for a period specified by the representative of the underwriters of the securities of the Company not to exceed one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act; provided that:

8.8.1 such agreement shall apply only to the Company’s first firm commitment underwritten public offering of its Ordinary Shares registered under the Securities Act; and

8.8.2 Xx. Xxx, Xxxx and all officers and directors of the Company enter into similar agreements.

The Company may impose stop-transfer instructions with respect to the Ordinary Shares (or other securities) subject to the foregoing restriction until the end of said one hundred eighty (180) day period. Each Holder agrees that any transferee of any shares of Registrable Securities shall be bound by this Clause 8.8.

8.9 Rule 144 Reporting

With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, or pursuant to registration on Form F-3 or Form S-3, the Company agrees to use its best efforts to:
