REGISTRATION RIGHTS

Section 2.01 Shelf Registration and Registration Procedures.

(a) Not later than the later of one hundred eighty (180) days after the commencement of the IPO or five business days after the expiration of the IPO Lock-up Period,

which shall be no later than two hundred thirty five (235) days after the commencement of the IPO (the “Commencement Date”), the Company shall (i) file a registration statement covering the resale of all of the Registrable Securities pursuant to Rule 415 under the Securities Act (or any successor or similar rule) (a “Shelf Registration” and the related registration statement, a “Shelf Registration Statement”), (ii) use commercially reasonable efforts to have the registration statement declared effective as promptly as practicable, and (iii) maintain an effective Shelf Registration (or other registration statement as described below) until all Registrable Securities shall have been sold under such Shelf Registration or cease to be Registrable Securities (such period, the “Effectiveness Period”). The Company shall promptly, and within two (2) Business Days after the Company confirms effectiveness of the Shelf Registration with the SEC, notify the Investors of the effectiveness of the Shelf Registration. In the event that Form S-3 or Form F-3 is not available for registration of the resale of the Registrable Securities hereunder, the Company shall (x) register the resale of the Registrable Securities on Form S-1 or Form F-1 or another appropriate form and (y) undertake to register the Registrable Securities on Form S-3 or Form F-3 as soon as the use of such form for such purpose is permitted, provided that the Company shall maintain the effectiveness of the registration statement then in effect until such time as the registration statement on Form S-3 or Form F-3 covering the Registrable Securities has been declared effective by the SEC.

(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, any post-effective amendment to incorporate by reference or otherwise include any such report, or any prospectus supplement to reflect changes in the selling stockholder table) the Company shall furnish to each participating Investor and each underwriter, if any, of the Registrable Securities covered by such registration statement copies of such registration statement as proposed to be filed. Such documents shall be subject to the review and comment of one counsel selected by the majority-in-interest of Investors participating in such registration. Thereafter the Company shall furnish to such Investor 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 Investor or underwriter may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor.

(c) The Company shall respond to written comments received from the SEC upon a review of any registration statement in a timely manner.

(d) 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, including as may be necessary to keep such registration statement effective and current, (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 Investors thereof set forth in such registration statement or supplement to such prospectus and (iii) promptly notify each Investor 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 reasonable best efforts to prevent the entry of such stop order or to cause it to be promptly removed if entered.

(e) The Company shall use 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 Investor holding such Registrable Securities reasonably (in light of such Investor’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 Investor to consummate the disposition of the Registrable Securities owned by such Investor; 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 2.01(d), (B) subject itself to taxation in any such jurisdiction, unless the Company is already subject to taxation in such jurisdiction or (C) consent to general service of process in any such jurisdiction, unless the Company is already subject to service in such jurisdiction, except as required pursuant to the applicable rules and regulations of the SEC.

(f) The Company shall promptly notify each Investor 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 Investor and file with the SEC any such supplement or amendment; provided that upon written notice to each Investor holding such Registrable Securities, the Company shall be entitled to delay the effectiveness of any registration statement or to suspend, on two occasions during any period of 12 consecutive months for a reasonable time specified in the notice but not exceeding in the aggregate 30 days (each, a “Suspension Period”), the use of any registration statement or prospectus if the Company determines in its reasonably good faith judgment, after consultation with counsel that (i) the registration statement or any prospectus may contain an untrue statement of a material fact or omit any fact necessary to make the statements in the registration statement or prospectus not misleading, provided, that in such event the Company shall promptly prepare and file a supplement or amendment to such registration statement or prospectus to correct such disclosure or (ii) proceeding with the registration would materially interfere with a significant acquisition, corporate organization or other similar transaction involving the Company, require premature disclosure of material information that the Company has bona fide business purposes for preserving as confidential or render the Company unable to comply with the requirements under the Securities Act or Exchange Act. Notwithstanding the foregoing, until such time as the Company is eligible to register the resale of Registrable Securities on Form S-3 or Form F-3, the Company shall be permitted to effect a Suspension Period to file a post-effective amendment to the registration statement at any time that the Company files a report under the Exchange Act; provided, that the Company shall use commercially reasonable efforts to file such post-effective amendment and have the registration statement declared effective as promptly as practicable.

(g) The Company shall use 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.

(h) The Company may require each Investor promptly to furnish in writing to the Company such information regarding the distribution of the Registrable Securities as the Company may reasonably request for inclusion in the registration statement (and the prospectus included therein) as is necessary to comply with all applicable rules and regulations of the SEC (the “Investor Information”), and that it will promptly notify the Company of any material changes in the information set forth in the registration statement furnished by or regarding the Investor or its plan of distribution.

(i) Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 2.01(e), such Investor shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.01(e), and, if so directed by the Company, such Investor shall deliver to the Company all copies, other than any permanent file copies then in such Investor’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.

(j) Each Investor 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, and will not distribute any written materials in connection with the offer or sale of the Registrable Securities pursuant to any Public Offering conducted hereunder other than the prospectus and any such free writing prospectus so authorized.

(k) The Company shall use commercially reasonable efforts to list all Registrable Securities on any securities exchange or quotation system on which any of the Registrable Securities are then listed or traded.

(l) The Company shall be liable for and pay all Registration Expenses incurred in connection with a registration statement pursuant to this Agreement, other than Selling Expenses. Selling Expenses shall be borne by the respective Investors on behalf of which the Selling Expenses have been incurred, in proportion to the respective number of shares of Registrable Securities sold by each of them.

(m) The Company shall not agree to name any Investor as an “underwriter” in any registration statement registering Registrable Securities without the prior written consent of such Investor. In addition, any registration statement registering Registrable Securities shall include a plan of distribution reasonably acceptable to the Investors.

Section 2.02 Rule 144 Sales; Cooperation by the Company. With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities Act and any

other rule or regulation of the SEC that may at any time permit the Investors to sell Registrable Securities to the public without registration, the Company agrees to use 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 date hereof;

(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; and

(c) furnish to each Investor 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 Investor may reasonably request in order to avail itself of any rule or regulation of the SEC allowing such Investor to sell any Registrable Securities without registration.

Section 2.03 Conversions of Ordinary Shares into ADSs. To the extent that the Company causes ADSs to be issued in the IPO, following the IPO and as requested by the Investors, the Company will deposit Ordinary Shares held by the Investors from time to time with the ADS depositary and cause the ADS depositary to issue ADSs to the Investors upon deposit of such Ordinary Shares, provided that the Company shall not be required to deposit such Ordinary Shares in exchange for ADSs (a) on or prior to the date that is six (6) months from the date of the final prospectus for the IPO except in compliance with the Securities Act, (b) at any time at which to do so would violate obligations under any underwriter’s lock-up agreement entered into in connection with the IPO. The Company will pay reasonable expenses of the Investors related to the issuance of ADSs upon exchange of Ordinary Shares for ADSs.

Section 2.04 Obligation to Register ADSs. Notwithstanding anything to the contrary herein, unless the Company has previously caused the Ordinary Shares to be listed on a national securities exchange or trading system in the United States (it being acknowledged that the Company shall have no obligation to so list the Ordinary Shares) and a market in the United States for Ordinary Shares not held in the form of ADSs exists, in any registration pursuant to Section 2.01 or Section 2.03 any Registrable Securities registered and sold pursuant thereto shall be in the form of ADSs.

ARTICLE III

PUBLIC OFFERING

Section 3.01 Participation in Public Offering. At any time after the Commencement Date, if the Company receives a request from an Investor or group of Investors, in each case holding a majority of the Registrable Securities (as determined on a fully-diluted basis) that the Company effect a Public Offering, then the Company shall use commercially reasonable efforts to promptly prepare a prospectus or a prospectus supplement to effect such Public Offering; provided that (i) the Company shall only be required to effectuate one Public Offering within any one-year period and (ii) the Company shall not be obligated to effect a Public Offering unless the

aggregate proceeds expected to be received from the sale of the Registrable Securities requested to be included in such Public Offering equals or exceeds $7,500,000. The Company shall use commercially reasonable efforts to give notice of such Public Offering at least ten (10) Business Days prior to the anticipated filing date of the prospectus or prospectus supplement relating to such Public Offering to the other Investors who hold Registrable Securities at such time. Such other Investors may, upon notice received by the Company no later than five (5) Business Days after the date of notice of a Public Offering, request that the Company also include all or any portion of such other Investors’ Registrable Securities. Thereafter, the Company shall use commercially reasonable efforts to effect the Public Offering of all Registrable Securities requested to be included (in accordance with the methods thereof as aforesaid). Subject to Section 3.03(b), the Company shall be permitted to include any securities other than the Registrable Securities (including for the benefit of Persons not party to this Agreement) as part of any such Public Offering.

Section 3.02 Other Agreements of Investors. No Investor may participate in any Public Offering hereunder unless such Investor (i) agrees to sell such Investor’s Registrable Securities on the basis provided in any underwriting arrangements (in customary form) approved by the Company and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lock up agreements and other documents reasonably required under the terms of such underwriting arrangements and the provisions of this Agreement in respect of registration rights within the specified timelines.

Section 3.03 Underwriting of Public Offering. 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.

(a) In connection with any Public Offering, if required, the Company shall 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.

(b) If the total amount of securities to be sold in any Public Offering in which the Investors are participating exceeds the amount that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities and securities other than the Registrable Securities that the underwriters and the Company determine in their sole discretion shall not jeopardize the success of the offering. If the Investors determine to include any Registrable Securities in any such Public Offering, other than a Public Offering initiated by the Company, the number of securities that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (i) first, securities other than the Registrable Securities requested to be included in such offering (including any securities that the Company proposes to register and sell for its own account) shall be excluded (as may be allocated pursuant to any agreement between holders of any such securities other than the Company) and (ii) second, Registrable Securities requested to be included in such offering by the

Investors shall be excluded on a pro rata basis based on the number of securities requested to be included. If the Investors determine to include any Registrable Securities in any such Public Offering initiated by the Company, the number of securities that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (i) first, securities other than the Registrable Securities requested to be included in such offering by Persons other than the Company shall be excluded on a pro rata basis based on the number of such securities requested to be included, (ii) second, Registrable Securities requested to be included in such offering by the Investors shall be excluded on a pro rata basis based on the number of such securities requested to be included and (iii) third, securities proposed to be registered and sold for the account of the Company shall be excluded. To facilitate the allocation of securities in accordance with the above provisions, the Company or the underwriters may round down the number of securities allocated to any selling holder (including each Investor) to the nearest 100.

Section 3.04 Inspection of the Company Records. 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 underwriter participating in such Public Offering and any attorney, accountant or other professional (the retention of which is reasonable under the circumstances) retained by any such 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 in accordance with applicable law, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any Inspectors in connection with such Public Offering and in accordance with applicable law. 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 the registration statement related to such Public Offering or (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction. Each Investor 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 Ordinary Shares, ADSs or other securities of the Company unless and until such information is made generally available to the public. Each Investor 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.

Section 3.05 The Company’s Participation in Road Shows. In connection with any Public Offering, 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 commercially reasonable efforts to cooperate as reasonably requested by the underwriters in the offering, marketing or selling of the Registrable Securities.

The Company agrees to indemnify and hold harmless each Investor beneficially owning any Registrable Securities covered by a registration statement, its officers, directors, partners, managers, members, investment managers, affiliates, agents, representatives and employees, and each Person, if any, who controls such Investor 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 and documented expenses of investigation and reasonable and documented attorneys’ fees and expenses) (collectively, “Damages”) caused by or relating to (i) any untrue statement or alleged untrue statement of a material fact contained in (or incorporated by reference 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 any filing under any state securities (or blue sky) laws, (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 state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law applicable to the Company, 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 Investor or on such Investor’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 Investors provided in this Section 4.01.

Section 4.02 Indemnification by Participating Investors. Each Investor holding Registrable Securities covered by a 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 from any Damages caused by or relating to (i) any untrue statement or alleged untrue statement of a material fact contained in (or incorporated by reference 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 any filing under any state securities (or blue sky) laws, (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, but only in each case with respect to information furnished in writing by such Investor or on such Investor’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. Each such Investor 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 either 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 4.02. 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 Investor shall be liable under this Section 4.02 for any Damages in excess of the net proceeds realized by such Investor in the sale of Registrable Securities of such Investor to which such Damages relate.

Section 4.03 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 Section 4.01 or 4.02, 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 reasonable and documented 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 or (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. 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 and documented 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. 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 includes an unconditional release of such Indemnified Party from all liability arising out of such proceeding.

Section 4.04 Survival. Unless otherwise superseded by an underwriting agreement entered into in connection with an underwritten public offering, the obligations of the Company and the Investors under Section 4.01 and Section 4.02, respectively, shall survive the completion of any offering of Registrable Securities in a registration statement under this Agreement or otherwise.

Section 4.05 Contribution. (a) If the indemnification provided for in Section 4.01 or 4.02 is unavailable to 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 as a result of such Damages:

(i) as between the Company and the Investors holding Registrable Securities covered by a registration statement on the one hand and the underwriters on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company and such Investors on the one hand and the underwriters on the other, from the offering of the Registrable Securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company and such Investors on the one hand and of such underwriters on the other in connection with the statements or omissions that resulted in such Damages, as well as any other relevant equitable considerations; and

(ii) as between the Company on the one hand and each such Investor on the other, in such proportion as is appropriate to reflect the relative fault of the Company and of each such Investor in connection with such statements or omissions, as well as any other relevant equitable considerations.

The relative benefits received by the Company and such Investors on the one hand and such underwriters on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and such Investors bear to the total underwriting discounts and commissions received by such underwriters, in each case as set forth in the table on the cover page of the applicable prospectus or prospectus supplement. The relative fault of the Company and such Investors on the one hand and of such underwriters on the other shall be determined 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 Company and such Investors or by such underwriters. The relative fault of the Company on the one hand and of each such Investor on the other shall be determined 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 such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(b) The Company and the Investors agree that it would not be just and equitable if contribution pursuant to this Section 4.05 were determined by pro rata allocation (even if the underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.05, no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any Damages that such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no

Investor shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable Securities of such Investor were offered to the public (less underwriters’ discounts and commissions) exceeds the amount of any Damages that such Investor has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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. Each Investor’s obligation to contribute pursuant to this Section 4.05 is several in the proportion that the proceeds of the offering received by such Investor bears to the total proceeds of the offering received by all such Investors and not joint.

(a) This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, successors, legal representatives and permitted assigns.

(a) Neither this Agreement nor any right, remedy, obligation or liability arising hereunder or by reason hereof shall be assignable by any party hereto pursuant to any Transfer of Registrable Securities or otherwise, except that each Investor may assign all or any portion of its rights hereunder to any Permitted Transferee of such Investor with respect to securities representing not less than twenty percent (20%) of the Registrable Securities held by such Investor as of the date of completion of the IPO; provided, however, that no such minimum assignment requirement shall be necessary for an assignment by an Investor which is (i) a partnership to its partners in accordance with their partnership interests, (ii) a limited liability company to its members in accordance with their interests in the limited liability company, (iii) a corporation to its stockholders in accordance with their interests in the corporation or (iv) to an Affiliate of such Investor.

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 5.02 shall be deemed effective service of process on such party.

EACH OF THE COMPANY AND THE INVESTORS (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT EACH OF THE COMPANY AND THE INVESTORS HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 5.07 Specific Enforcement.

shall, taken together, be considered one and the same agreement, it being understood that each party need not sign the same counterpart. This Agreement shall become effective when each party hereto shall have executed and delivered this Agreement. Until and unless each party has executed and delivered this Agreement, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 5.09 Entire Agreement. This Agreement constitutes the entire agreement and understanding among the parties hereto with respect to the subject matter of this Agreement and supersedes all prior and contemporaneous agreements and understandings, both oral and written, among the parties hereto with respect to the subject matter hereof.

Section 5.10 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. 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 5.11 Confidentiality.

(a) Each Investor agrees that any notice received pursuant to this Agreement, including any notice of a proposed public offering, postponement of an offering or other similar notice regarding the Company’s securities, 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.

(b) Each Investor shall have the right, at any time and from time to time (including after receiving information regarding any potential Public Offering), to elect not to receive any notice that the Company or any other Investor otherwise are required to deliver pursuant to this Agreement by delivering to the Company a written statement signed by such Investor that it does not want to receive any notices hereunder (an “Opt-Out Request”); in which case and notwithstanding anything to the contrary in this Agreement the Company and other Investors shall not be required to, and shall not, deliver any notice or other information required to be provided to Investors hereunder to the extent that the Company or such other Investors reasonably expect would result in an Investor acquiring material nonpublic information. An Opt-Out Request may state a date on which it expires or, if no such date is specified, shall remain in effect indefinitely. An Investor who previously has given the Company an Opt-Out Request may revoke such request at any time, and there shall be no limit on the ability of an Investor to issue and revoke a subsequent Opt-Out Request.

Section 5.12 Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor hereunder are several and not joint with the obligations of any other Investor hereunder, and no Investor shall be responsible in any way for the performance of the obligations

of any other Investor hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Investor pursuant hereto or thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each Investor 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 Investor to be joined as an additional party in any proceeding for such purpose.
