REGISTRATION RIGHTS

Section 2.01. Demand Registration. (a) If at any time after the date six months after the completion of the First Public Offering, the Company shall receive a request from a Shareholder or group of Shareholders (the requesting Shareholder(s) shall be referred to herein as the “Requesting Shareholder”) that the Company effect the registration under the Securities Act of all or any portion of the Requesting Shareholder’s Registrable Securities, and specifying the intended method of disposition thereof, then the Company shall as promptly as practicable following the date of receipt by the Company of such request give notice of such requested registration (each such request shall be referred to herein as a “Demand Registration”) at least 10 Business Days prior to the anticipated filing date of the registration statement relating to such Demand Registration to the other Shareholders and thereupon shall use its commercially reasonable efforts to effect, as expeditiously as possible, the registration under the Securities Act of:

(i) subject to the restrictions set forth in Sections 2.01(e), all Registrable Securities for which the Requesting Shareholder has requested registration under this Section 2.01, and

(ii) subject to the restrictions set forth in Sections 2.01(e) and 2.02, all other Registrable Securities of the same class as those requested to be registered by the Requesting Shareholder that any Shareholders (all such Shareholders, together with the Requesting Shareholder, the “Registering Shareholders”) have requested the Company to register pursuant to Section 2.02, by request received by the Company within seven Business Days after such Shareholders receive the Company’s notice of the Demand Registration,

all to the extent necessary to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be registered, provided that, the Company shall not be obligated to effect a Demand Registration unless the aggregate proceeds expected to be received from the sale of the Registrable Securities requested to be included in such Demand Registration equals or exceeds, in the case of the First Demand Registration, $25,000,000, and thereafter $15,000,000. In no event shall the Company be required to effect more than one Demand Registration hereunder within any six-month period or any Demand Registration if, at the time of such request, three or more Demand Registrations and Underwritten Takedowns have previously been exercised.

(b) Promptly after the expiration of the seven-Business Day period referred to in Section 2.01(a)(ii), the Company will notify all Registering Shareholders of the identities of the other Registering Shareholders and the number of shares of Registrable Securities requested to be included therein. At any time prior to the effective date of the registration statement relating to such registration, the Requesting Shareholder may revoke such request, without liability to any of the other Registering Shareholders, by providing a notice to the Company revoking such request. Notwithstanding clause (d) below, a request, so revoked, shall be considered to be a Demand Registration unless (i) such revocation arose out of the fault of the Company (in which case the Company shall be obligated to pay all Registration Expenses in connection with such revoked request), or (ii) the Requesting Shareholder reimburses the Company for all Registration Expenses (other than the expenses set forth under clause (v) of the definition of the term Registration Expenses) of such revoked request.

(c) The Company shall be liable for and shall pay all Registration Expenses in connection with any Demand Registration, regardless of whether such Registration is effected, unless the Requesting Shareholder elects to pay such Registration Expenses as described in the last sentence of Section 2.01(b).

(d) A Demand Registration shall not be deemed to have occurred unless the registration statement relating thereto (i) has become effective under the Securities Act and (ii) has remained effective for a period of at least 180 days (or such shorter period in which all Registrable Securities of the Registering Shareholders included in such registration have actually been sold thereunder), provided that a Demand Registration shall not be deemed to have occurred if, after such registration statement becomes effective, such registration statement is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental agency or court.

(e) If a Demand Registration involves an underwritten Public Offering and the managing underwriter advises the Company and the Requesting Shareholder that, in its view, the number of shares of Registrable Securities requested to be included in such registration (including any securities that the Company proposes to be included that are not Registrable Securities) exceeds the largest number of shares that can be sold without having an adverse effect on such offering, including the price at which such shares can be sold (the “Maximum Offering Size”), the Company shall include in such registration, in the priority listed below, up to the Maximum Offering Size:

(i) first, all Registrable Securities requested to be included in such registration by all Registering Shareholders (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such Shareholders on the basis of the relative number of Registrable Securities held by each such Shareholder); and

(ii) second, any securities proposed to be registered by the Company (including for the benefit of any other Persons not party to this Agreement).

(f) Upon notice to the Requesting Shareholder, the Company may postpone effecting a registration pursuant to this Section 2.01 on two occasions during any period of twelve consecutive months for a reasonable time specified in the notice but not exceeding 90 days in the aggregate in any period of twelve consecutive months (which period may not be extended or renewed), if (i) the Company reasonably determines that effecting the registration would materially and adversely affect an offering of securities of the Company the preparation of which had then been commenced, or (ii) the Company is in possession of material non-public information the disclosure of which during the period specified in such notice the Company reasonably believes in good faith would not be in the best interests of the Company.

Section 2.02. Piggyback Registration. (a) If at any time after the completion of the First Public Offering the Company proposes to register any Company Securities under the Securities Act (other than (i) a Shelf Registration, which will be subject to the provisions of Section 2.03; provided that any Underwritten Takedown will be subject to this Section 2.02, or (ii) a registration on Form S-8, F-4 or S-4, or any successor or similar forms, relating to Ordinary Shares issuable upon exercise of employee stock options or in connection with any employee benefit or similar plan of the Company or in connection with a direct or indirect acquisition by the Company of another Person), whether or not for sale for its own account, the Company shall each such time give prompt notice at least ten Business Days prior to the anticipated filing date of the registration statement relating to such registration to each Shareholder, which notice shall set forth such

Shareholder’s rights under this Section 2.02 and shall offer such Shareholder the opportunity to include in such registration statement the number of Registrable Securities of the same class or series as those proposed to be registered as each such Shareholder may request (a “Piggyback Registration”), subject to the provisions of Section 2.02(b). Upon the request of any such Shareholder made within five Business Days after the receipt of notice from the Company (which request shall specify the number of Registrable Securities intended to be registered by such Shareholder), the Company shall use all commercially reasonable efforts to effect the registration under the Securities Act of all Registrable Securities that the Company has been so requested to register by all such Shareholders, to the extent required to permit the disposition of the Registrable Securities so to be registered, provided that (A) if such registration involves an underwritten Public Offering, all such Shareholders requesting to be included in the Company’s registration must sell their Registrable Securities to the underwriters selected as provided in Section 2.05(f) on the same terms and conditions as apply to the Company or the Requesting Shareholders, as applicable, and (B) if, at any time after giving notice of its intention to register any Company Securities pursuant to this Section 2.02(a) and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register such securities, the Company shall give notice to all such Shareholders and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration. No registration effected under this Section 2.02 shall relieve the Company of its obligations to effect a Demand Registration to the extent required by Section 2.01 or a Shelf Registration to the extent required by Section 2.03. The Company shall pay all Registration Expenses in connection with each Piggyback Registration.

(b) If a Piggyback Registration involves an underwritten Public Offering (other than any Demand Registration, in which case the provisions with respect to priority of inclusion in such offering set forth in Section 2.01(e) shall apply) and the managing underwriter advises the Company that, in its view, the number of Shares that the Company and such Shareholders intend to include in such registration exceeds the Maximum Offering Size, the Company shall include in such registration, in the following priority, up to the Maximum Offering Size:

(i) first, so much of the Company Securities proposed to be registered for the account of the Company (or, if such registration is pursuant to a demand by a Person that is not a Shareholder, for the account of such other Person) as would not cause the offering to exceed the Maximum Offering Size,

(ii) second, all Registrable Securities requested to be included in such registration by any Shareholders pursuant to this Section 2.02 (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such Shareholders on the basis of the relative number of shares of Registrable Securities so requested to be included in such registration by each), and

(iii) third, any securities proposed to be registered for the account of any other Persons with such priorities among them as the Company shall determine.

Section 2.03. Shelf Registration. (a) At any time after the first anniversary of the First Public Offering, if the Company is eligible to use Form F-3 or Form S-3, a Shareholder or group of Shareholders may request the Company (the requesting Shareholder(s) shall be referred to herein as the “Shelf Requesting Shareholder”) to effect a registration of some or all of the Registrable Securities held by such Shelf Requesting Shareholder under a Registration Statement pursuant to Rule 415 under the Securities Act (or any successor or similar rule) (a “Shelf Registration”). The Company shall only be required to effectuate one Public Offering from such Shelf Registration (an “Underwritten Takedown”) within any six-month period. The provisions of Section 2.01 shall apply mutatis mutandis to each Underwritten Takedown, with references to “filing of the registration statement” or “effective date” being deemed references to filing of a prospectus or supplement for such offering and references to “registration” being deemed references to the offering; provided that Registering Shareholders shall only include Shareholders whose Registrable Securities are included in such Shelf Registration or may be included therein without the need for an amendment to such Shelf Registration (other than an automatically effective amendment). So long as the Shelf Registration is effective, no Shareholder may request any Demand Registration pursuant to Section 2.01 with respect to Registrable Shares that are registered on such Shelf Registration but instead shall have the right to request an Underwritten Takedown as set forth above.

(b) If the Company shall receive a request from a Shelf Requesting Shareholder that the Company effect a Shelf Registration, then the Company shall as promptly as practicable following the date of receipt by the Company of such request give notice of such requested registration and at least ten Business Days prior to the anticipated filing date of the registration statement relating to such Shelf Registration to the other Shareholders and thereupon shall use its reasonable best efforts to effect, as expeditiously as possible, the registration under the Securities Act of:

(i) all Registrable Securities for which the Shelf Requesting Shareholder has requested registration under this Section 2.03, and

(ii) all other Registrable Securities of the same class as those requested to be registered by the Shelf Requesting Shareholder that any Shareholders (all such Shareholders, together with the Shelf Requesting Shareholder, the “Shelf Registering Shareholders”) have requested the

Company to register by request received by the Company within five Business Days after such Shareholders receive the Company’s notice of the Shelf Registration,

all to the extent necessary to permit the registration of the Registrable Securities so to be registered on such Shelf Registration.

(c) At any time prior to the effective date of the registration statement relating to such Shelf Registration, the Shelf Requesting Shareholder may revoke such request, without liability to any of the other Shelf Registering Shareholders, by providing a notice to the Company revoking such request.

(d) The Company shall be liable for and pay all Registration Expenses in connection with any Shelf Registration.

(e) Upon notice to the Shelf Registering Shareholders, the Company may postpone effecting a registration pursuant to this Section 2.03 on two occasions during any period of twelve consecutive months for a reasonable time specified in the notice but not exceeding 90 days in the aggregate in any period of twelve consecutive months (which period may not be extended or renewed), if the Company determines that effecting the registration would materially and adversely affect an offering of securities of the Company the preparation of which had then been commenced, or the Company is in possession of material non-public information the disclosure of which during the period specified in such notice the Company reasonably believes in good faith would not be in the best interests of the Company.

Section 2.04. Registration Procedures. Whenever Shareholders request that any Registrable Securities be registered pursuant to Section 2.01 or 2.02, or the Company prepares a Shelf Registration pursuant to Section 2.03, subject to the provisions of such Sections, the Company shall use all commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof as quickly as practicable, and, in connection with any such request:

(a) The Company shall as expeditiously as possible prepare and file with the SEC a registration statement on any form for which the Company then qualifies or that counsel for the Company shall deem appropriate and which form shall be available for the sale of the Registrable Securities to be registered thereunder in accordance with the intended method of distribution thereof, and use all commercially reasonable efforts to cause such filed registration statement to become and remain effective for a period of not less than 180 days, or in the case of a Shelf Registration, three years (or such shorter period in which all of the Registrable Securities of the Shareholders included in such registration statement

shall have actually been sold thereunder or cease to be Registrable Securities). Any such registration statement shall be an automatically effective registration statement to the extent permitted by the SEC’s rules and regulations.

(b) Prior to filing a registration statement or prospectus or any amendment or supplement thereto (other than any report filed pursuant to the Exchange Act that is incorporated by reference therein), the Company shall, if requested, furnish to each participating Shareholder and each underwriter, if any, of the Registrable Securities covered by such registration statement copies of such registration statement as proposed to be filed, and thereafter the Company shall furnish to such Shareholder and underwriter, if any, such number of copies of such registration statement, each amendment and supplement thereto (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such registration statement (including each preliminary prospectus and any summary prospectus) and any other prospectus filed under Rule 424, Rule 430A, Rule 430B or Rule 430C under the Securities Act and such other documents as such Shareholder or underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Shareholder.

(c) After the filing of the registration statement, the Company shall (i) cause the related prospectus to be supplemented by any required prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424 under the Securities Act, (ii) comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such registration statement during the applicable period in accordance with the intended methods of disposition by the Shareholders thereof set forth in such registration statement or supplement to such prospectus and (iii) promptly notify each Shareholder holding Registrable Securities covered by such registration statement of any stop order issued or threatened by the SEC or any state securities commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered.

(d) The Company shall use all commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by such registration statement under such other securities or “blue sky” laws of such jurisdictions in the United States as any Registering Shareholder holding such Registrable Securities reasonably (in light of such Shareholder’s intended plan of distribution) requests and (ii) cause such Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be reasonably necessary or advisable to enable such Shareholder to consummate the disposition of the Registrable Securities owned by such Shareholder, provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be

required to qualify but for this Section 2.04(d), (B) subject itself to taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction.

(e) The Company shall immediately notify each Shareholder holding such 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 occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and promptly prepare and make available to each such Shareholder and file with the SEC any such supplement or amendment.

(f) The Company shall have the right to select an underwriter or underwriters in connection with any Public Offering resulting from any exercise of a Demand Registration (including any Underwritten Takedown), which underwriter or underwriters shall be reasonably acceptable to the Requesting Shareholder. In connection with any Public Offering, the Company shall enter into customary agreements (including an underwriting agreement in customary form) and take such all other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities in any such Public Offering, including the engagement of a “qualified independent underwriter” in connection with the qualification of the underwriting arrangements with FINRA.

(g) Upon execution of confidentiality agreements in form and substance reasonably satisfactory to the Company, the Company shall, in connection with a Public Offering make available for inspection by any Shareholder and any underwriter participating in any disposition pursuant to a registration statement being filed by the Company pursuant to this Section 2.04 and any attorney, accountant or other professional retained by any such Shareholder or underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”) as shall be reasonably necessary or desirable to enable any of the Inspectors to exercise its due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any Inspectors in connection with such registration statement. Records that the Company determines, in good faith, to be confidential and that it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (i) the disclosure of such Records is necessary to avoid or correct a material misstatement or omission in such registration statement or (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction. Each Shareholder agrees that information obtained by it as a result of such inspections

shall be deemed confidential and shall not be used by it or its Affiliates as the basis for any market transactions in the Company Securities unless and until such information is made generally available to the public. Each Shareholder further agrees that, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, it shall give notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential.

(h) In connection with any Public Offering, the Company shall use its reasonable best efforts to furnish to each underwriter, if any, a signed counterpart, addressed to such underwriter, of (i) an opinion or opinions of counsel to the Company and (ii) a comfort letter or comfort letters from the Company’s independent public accountants, each in customary form and covering such matters of the kind customarily covered by opinions or comfort letters, as the case may be, as the managing underwriter therefor reasonably requests.

(i) The Company shall otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement or such other document covering a period of 12 months, beginning within three months after the effective date of the registration statement, which earnings statement satisfies the requirements of Rule 158 under the Securities Act.

(j) The Company may require each Shareholder promptly to furnish in writing to the Company such information regarding the distribution of the Registrable Securities as the Company may from time to time reasonably request and such other information as may be legally required in connection with such registration. In connection with a Shelf Registration, any Shareholder that does not provide such information within five Business Days of a request by the Company (which request is made before filing of the Shelf Registration) may have its Registrable Securities excluded from such Shelf Registration; provided that such securities shall be added within fifteen Business Days after the Shareholder provides such information if the Company may add such securities to such Shelf Registration without the need for a post-effective amendment (other than an automatically effective amendment) to the Shelf Registration.

(k) Each Shareholder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.04(e), such Shareholder shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Shareholder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.04(e), and, if so directed by the Company, such Shareholder shall deliver to the Company all copies, other than any permanent file copies then in such Shareholder’s possession, of the most recent prospectus

covering such Registrable Securities at the time of receipt of such notice. If the Company shall give such notice, the Company shall extend the period during which such registration statement shall be maintained effective (including the period referred to in Section 2.04(a)) by the number of days during the period from and including the date of the giving of notice pursuant to Section 2.04(e) to the date when the Company shall make available to such Shareholder a prospectus supplemented or amended to conform with the requirements of Section 2.04(e).

(l) The Company shall use its reasonable best efforts to list all Registrable Securities covered by such registration statement on any securities exchange or quotation system on which the Ordinary Shares are then listed or traded.

(m) In any Public Offering pursuant to a Demand Registration, the Company shall have appropriate officers of the Company (i) prepare and make presentations at any “road shows” and before analysts and (ii) otherwise use their reasonable efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of the Registrable Securities.

(n) Each Shareholder agrees that, in connection with any offering pursuant to this Agreement, it will not prepare or use or refer to, any “free writing prospectus” (as defined in Rule 405 of the Securities Act) without the prior written authorization of the Company (which authorization shall not be unreasonably withheld), and will not distribute any written materials in connection with the offer or sale of the Registrable Securities pursuant to any registration statement hereunder other than the Prospectus and any such free writing prospectus so authorized.

Section 2.05. Participation In Public Offering. No Shareholder may participate in any Public Offering hereunder unless such Shareholder (a) agrees to sell such Shareholder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements that are consistent for all similarly situated Shareholders and the provisions of this Agreement in respect of registration rights.

Section 2.06. Rule 144 Sales; Cooperation By The Company. If any Shareholder shall transfer any Registrable Securities pursuant to Rule 144, the Company shall cooperate, to the extent commercially reasonable, with such Shareholder and shall provide to such Shareholder such information as such Shareholder shall reasonably request. Without limiting the foregoing, the Company shall at any time after any of the Company’s shares of capital stock are

registered under the Securities Act or the Exchange Act: (i) make and keep available public information, as those terms are contemplated by Rule 144; (ii) timely file with the SEC all reports and other documents required to be filed under the Securities Act and the Exchange Act; and (iii) furnish to each Shareholder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other information as such Shareholder may reasonably request in order to avail itself of any rule or regulation of the SEC allowing such Shareholder to sell any Registrable Securities without registration.

ARTICLE 3

INDEMNIFICATION AND CONTRIBUTION

Section 3.01. Indemnification by the Company. The Company agrees to indemnify and hold harmless each Shareholder beneficially owning any Registrable Securities covered by a registration statement, its officers, directors, employees, partners and agents, and each Person, if any, who controls such Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses) (collectively, “Damages”) caused by or relating to any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus relating to the Registrable Securities (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus or free-writing prospectus (as defined in Rule 405 under the Securities Act), or caused by or relating to 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, except insofar as such Damages are caused by or related to any such untrue statement or omission or alleged untrue statement or omission so made based upon information furnished in writing to the Company by such Shareholder or on such Shareholder’s behalf expressly for use therein. The Company also agrees to indemnify any underwriters of the Registrable Securities, their officers and directors and each Person who controls such underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Shareholders provided in this Section 3.01.

Section 3.02. Indemnification by Participating Shareholders. Each Shareholder holding Registrable Securities included in any registration statement agrees, severally but not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity from the Company to such

Shareholder provided in Section 3.01, but only to the extent such Damages arise out of or are based upon actions and omissions made in reliance upon and in conformity with information about such Shareholder furnished in writing by such Shareholder or on such Shareholder’s behalf expressly for use in any registration statement or prospectus relating to the Registrable Securities, or any amendment or supplement thereto, or any preliminary prospectus or free-writing prospectus. Each such Shareholder also agrees to indemnify and hold harmless underwriters of the Registrable Securities, their officers and directors and each Person who controls such underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act on substantially the same basis as that of the indemnification of the Company provided in this Section 3.02. As a condition to including Registrable Securities in any registration statement filed in accordance with Article 2, the Company may require that it shall have received an undertaking reasonably satisfactory to it from any underwriter to indemnify and hold it harmless to the extent customarily provided by underwriters with respect to similar securities. No Shareholder shall be liable under this Section 3.02 for any Damages in excess of the net proceeds realized by such Shareholder in the sale of Registrable Securities of such Shareholder to which such Damages relate.

Section 3.03. Conduct of Indemnification Proceedings. If any proceeding (including any governmental investigation) shall be brought or asserted against any Person in respect of which indemnity may be sought pursuant to this Article 3, such Person (an “Indemnified Party”) shall promptly notify the Person against whom such indemnity may be sought (the “Indemnifying Party”) in writing and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and expenses, provided that the failure of any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (a) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel, (b) in the reasonable judgment of such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, including one or more defenses or counterclaims that are different from or in addition to those available to the Indemnifying Party, or (c) the Indemnifying Party shall have failed to assume the defense within 30 days of notice pursuant to this Section 3.03. It is understood that, in connection with any proceeding or related proceedings in the same jurisdiction, the Indemnifying Party shall not be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to one local counsel per jurisdiction) at any time for all such Indemnified Parties, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate

firm for the Indemnified Parties, such firm shall be designated in writing by the Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the extent stated above) by reason of such settlement or judgment. Without the prior written consent of the Indemnified Party, no Indemnifying Party shall effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement (A) includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding, and (B) does not include any injunctive or other equitable or non-monetary relief applicable to or affecting such Indemnified Person.

Section 3.04. Contribution. If the indemnification provided for in this Article 3 is unavailable to or unenforceable by the Indemnified Parties in respect of any Damages, then each Indemnifying Party, in lieu of indemnifying the Indemnified Parties, shall contribute to the amount paid or payable by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Damages as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Damages shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Article 3 was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 3.04 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 3.04, no Shareholder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such Shareholder from the sale of the Registrable Securities subject to the proceeding exceeds the amount of any damages that such Shareholder has otherwise been required to pay by reason of

such untrue or alleged untrue statement or omission or alleged omission, except in the case of fraud by such Shareholder. Each Shareholder’s obligation to contribute pursuant to this Section 3.03 is several in the proportion that the proceeds of the offering received by such Shareholder bears to the total proceeds of the offering received by all such Shareholders and not joint.

No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The indemnity and contribution agreements contained in this Article 3 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties.

Section 3.05. Other Indemnification. Indemnification similar to that provided in this Article 3 (with appropriate modifications) shall be given by the Company and each Shareholder participating therein with respect to any required registration or other qualification of securities under any foreign, federal or state law or regulation or governmental authority other than the Securities Act.

ARTICLE 4

Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of

holders of Registrable Securities whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other holders of Registrable Securities may be given by holders of at least a majority of the Registrable Securities being sold by such holders pursuant to such Registration Statement.

Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 4.02 shall be deemed effective service of process on such party.

Section 4.08. Counterparts; Effectiveness.

Section 4.10. Severability.

Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner so that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 4.11. Other Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of holders of a majority of the Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are equivalent to or more favorable than the registration rights granted to Shareholders hereunder, or which would reduce the amount of Registrable Securities the Shareholders can include in any registration filed pursuant to this Agreement, unless such rights are subordinate to those of the Shareholders hereunder.

Section 4.12. Confidentiality. Each Shareholder agrees that any notice received pursuant to this Agreement, including any notice of a proposed underwritten public offering or postponement of an offering or effecting of a registration, is confidential information and that any trading in securities of the Company following receipt of such information may only be done in compliance with all applicable securities laws.

Section 4.13. Independent Nature of Shareholders’ Obligations and Rights.

Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Shareholder pursuant hereto or thereto, shall be deemed to constitute the Shareholders as a

partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Shareholders are in any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each Shareholder shall be entitled to protect and enforce its rights, including the rights arising out of this Agreement, and it shall not be necessary for any other Shareholder to be joined as an additional party in any proceeding for such purpose.
