Subject to the foregoing clauses (A) through (F), the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the Request for Registration. If as a result of a Demand Registration Cutback (as defined in Section 2.1(b) below) the Purchasers are not allowed to include in any such registration at least fifty percent (50%) of their Registrable Securities requested to be registered (whether or not a Purchaser initiated such request), then such registration shall not count as one of the Purchasers' three (3) Requests for Registration. (b) Underwriting. At the request of the Initiating Purchasers, the distribution of the Registrable Securities covered by a Request for Registration shall be effected by means of a firm commitment underwriting. The right of any Purchaser to registration pursuant to Section 2.1 shall be conditioned upon such Purchaser's participation in such underwriting and the inclusion of such Purchaser's Registrable Securities in the underwriting to the extent provided herein. The Company, together with all Purchasers proposing to distribute their securities through such underwriting, shall enter into an underwriting agreement in customary form with the managing underwriter(s) selected for such underwriting by the Company which underwriter(s) shall be reasonably acceptable to the Initiating Purchasers; provided, however, that no Purchaser shall be required to make any representations or warranties concerning the Company or its business, properties, prospects, financial condition or related matters. Notwithstanding any other provision of this Section 2.1, if the managing underwriter(s) advises the Company and the Purchasers in writing that because the number of shares requested by the Purchasers to be included in the registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Purchasers requesting registration or that marketing factors require a limitation of the number of shares to be underwritten on behalf of the Purchasers (the "DEMAND REGISTRATION CUTBACK"), then the Company will include in such registration, to the extent of the number and type which the Company is 11 so advised can be sold in (or during the time of) such offering without such interference or affect on the price or sale, first, all Registrable Securities requested to be included by the Purchasers and second, the securities proposed to be sold by the Company for its own account. In the event a Demand Registration Cutback results in less than all of the Registrable Securities of the Purchasers that are requested to be included in such registration to actually be included in such registration, then the number of Registrable Securities that will be included in such registration shall be shared pro rata among all of the Purchasers of Registrable Securities that were requested to be included in such registration based on the number of shares held by each such Purchaser. If any Purchaser disapproves of the terms of the underwriting, such Person may elect to withdraw therefrom by written notice to the Company, the managing underwriter(s) and the other Purchasers. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration; provided, however, that, if by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by the other Purchasers may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to the Purchasers who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same proportion used in determining the underwriter limitation in this Section 2.1(b). 2.2 Company Registration. (a) Notice of Registration to Purchasers. If at any time or from time to time, the Company shall determine to register any of its securities, either for its own account or the account of a security holder or holders, other than (i) a registration relating solely to employee benefit plans, or (ii) a registration relating solely to a Commission Rule 145 transaction, the Company will: (i) promptly give to each Purchaser written notice thereof; and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made within twenty (20) days after receipt of such written notice from the Company, by any Purchaser or Purchasers, subject to the Company Registration Cutback. (b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Purchasers as a part of the written notice given pursuant to Section 2.2(a)(i). In such event the right of any Purchaser to registration pursuant to this Section 2.2 shall be conditioned upon such Purchaser's participation in such underwriting and the inclusion of such Purchaser's Registrable Securities in the underwriting to the extent provided herein. All Purchasers proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their Registrable Securities through such underwriting) enter into an underwriting 12 agreement in the form agreed to by the Company and the managing underwriter selected for such underwriting by the Company; provided, however, that no Purchaser shall be required to make any representations or warranties concerning the Company or its business, properties, prospects, financial condition or related matters. Notwithstanding any other provision of this Section 2.2, if the managing underwriter determines that the number of shares requested to be included in the registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Company or that marketing factors require a limitation of the number of shares to be underwritten on behalf of the Company (the "COMPANY REGISTRATION CUTBACK"), then the Company will include in such registration, to the extent of the number and type which the Company is so advised can be sold in (or during the time of) such offering without such effect on the price or sale, first, all securities of the Company proposed to be sold by the Company for its own account, second, the Registrable Securities requested by the Purchasers to be included in such registration, and finally, any other securities of the Company requested by other Stockholders to be included in such registration. In the event a Company Registration Cutback results in less than all of the securities of a particular category identified in the immediately preceding sentence that are requested to be included in such registration to actually be included in such registration, then the number of securities of such category that will be included in such registration shall be shared pro rata among all of the holders of securities of such category that were requested to be included in such registration based on the number of shares held by each holder of securities of such category. 2.3 Expenses of Registration. All Registration Expenses incurred in connection with any registration pursuant to Sections 2.1, 2.2 and 2.5, other than Selling Expenses and the fees of counsel for any selling Stockholders (except for the reasonable fees and expenses of one counsel to the Purchasers, which shall be paid by the Company), shall, to the extent permitted by applicable law, be borne by the Company. All Selling Expenses relating to Registrable Securities registered by the Purchasers shall be borne by the Purchasers holding such Registrable Securities pro rata on the basis of the number of shares so registered. 2.4 Registration Procedures. In the case of each registration effected by the Company pursuant to this Agreement, the Company will keep each Purchaser advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. The Company will: (a) keep such registration, qualification or compliance effective and current for a period of 180 days (or such longer period as may be necessary to accommodate the filing of amendments or supplements necessary to comply with the Securities Act) or until the Purchaser or Purchasers have completed the distribution described in the registration statement relating thereto, whichever first occurs; (b) furnish such number of prospectuses and other documents incident thereto as a Purchaser from time to time may reasonably request; 13 (c) use commercially reasonable efforts to register or qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as any seller holding at least 10% of the Registrable Securities then being registered reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller; (d) 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 of such offering. Each Purchaser participating in such underwriting shall also enter into and perform its obligations under such an agreement; provided, however, that no Purchaser shall be required to make any representations or warranties concerning the Company or its business, properties, prospects, financial condition or related matters; (e) notify each Purchaser with Registrable Securities covered by such registration statement, at any time when a prospectus relating thereto covered by such registration statement 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 and of any Commission stop orders or other material modifications in connection therewith. In such case, the Company shall promptly prepare a supplement or amendment to such prospectus and furnish to each seller of Registrable Securities a reasonable number of copies of such supplement to or an amendment of such prospectus as may be necessary so that, after delivery to the purchasers of such Registrable Securities, such prospectus shall 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, in light of the circumstances under which they were made, not misleading; (f) cause all such Registrable Securities covered by such registration statement to be listed on each securities exchange on which the same class of securities issued by the Company are then listed, if the listing of such Registrable Securities is then permitted under the rules and regulations of such exchange or if applicable, as a NASDAQ National Market system security and, if requested by the Purchasers holding Registrable Securities, cause all such Registrable Securities, if the Company's securities are not already listed or traded, to be listed on any securities exchange or if applicable, as a NASDAQ National Market system security reasonably requested by the Purchasers; 14 (g) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of such registration statement; (h) enter into such customary agreements (including underwriting agreements in customary form) and take all such other actions as the Purchasers or the underwriters, if any, reasonably request to expedite or facilitate the disposition of such Registrable Securities (including effecting a stock split or a combination of shares); (i) make available for inspection by any Purchaser who is selling Registrable Securities, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement; (j) otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first day of the Company's first full calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; (k) permit any Purchaser which, in its reasonable judgment, might be deemed to be an underwriter or a controlling Person of the Company, to participate in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such Purchasers and their counsel should be included; (l) in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Registrable Securities included in such registration statement for sale in any jurisdiction, the Company shall use commercially reasonable efforts promptly to obtain the withdrawal of such order; (m) use commercially reasonable efforts to cause such Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Securities; and 15 (n) obtain (A) a cold comfort letter from the Company's independent accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the holders of a majority of Registrable Securities being sold pursuant to the applicable registration statement may reasonably request and (B) an opinion 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. (o) In the event of any underwritten public offering, cooperate with the Purchasers requesting registration, the underwriters participating in the offering and their counsel in any due diligence investigation reasonably requested by the Purchasers or the underwriters in connection therewith, and participate, to the extent reasonably requested by the underwriter for the offering or the Purchasers, in efforts to sell the Registrable Securities under the offering (including, without limitation, participating in "ROADSHOW" meetings with prospective investors) that would be customary for underwritten primary offerings of a comparable amount of equity securities by the Company; (p) cooperate, to the extent reasonably requested, with each underwriter participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the NASD; and (q) take all other steps reasonably necessary to effect the registration of the Registrable Securities contemplated hereby. 2.5 Registration on Form S-3. In addition to the rights set forth in Sections 2.1 and 2.2, if the Purchasers request that the Company file a registration statement on Form S-3 (or any successor form to Form S-3) for a public offering of shares of Registrable Securities, and the Company is a registrant entitled to use Form S-3 (or any successor form to Form S-3) to register the Registrable Securities for such an offering, the Company shall use its best efforts to cause such shares to be registered for the offering as soon as practicable on Form S-3 (or any successor form to Form S-3). The procedures and other limitations for effecting the registration of the Registrable Securities on Form S-3 (or any successor form to Form S-3), including the procedure used for any underwriting limitation, shall be as set forth in Section 2.1(b) above; provided, however, that (i) there shall not be any limit on the number of registrations that may be requested by the Purchasers on Form S-3 (or any successor form to Form S-3) and (ii) the Company shall not be obligated to effect a registration under this Section 2.5 if the minimum estimated dollar value of any offering of Registrable Securities pursuant to this Section 2.5 is less than $1,000,000. 2.6 Indemnification. 16 (a) The Company will indemnify each Purchaser, each of its officers and directors and partners and such Purchaser's legal counsel, and each Person controlling any such Persons within the meaning of Section 15 of the Securities Act, with respect to which any registration, qualification or compliance has been effected pursuant to this Agreement, and each underwriter, if any, and each Person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in the investigation or settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, or based on 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 any violation by the Company of any rule or regulation promulgated under the Securities Act or any state securities laws applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each such Purchaser, each of its officers and directors and such Purchaser's legal counsel, and each Person controlling any such Persons, each such underwriter and each Person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Purchaser or underwriter and stated to be specifically for use therein and provided, further, that with respect to an untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus or prospectus, the indemnification provided for herein shall not apply to any loss, liability, claim, damage or expense to the extent the same results from the sale of Registrable Securities to a person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the prospectus, or in the case of an untrue statement or omission or alleged untrue statement or omission in the prospectus, a copy of the amended prospectus or supplement thereto, if the Company shall have previously furnished sufficient copies thereof, based upon the number of copies requested by the Purchaser, to the Purchaser a reasonable time in advance and the claim, damage or expense of such person results from an untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in a preliminary prospectus or prospectus that was corrected in the prospectus or amendment or supplement thereto. (b) Each Purchaser will, if Registrable Securities held by such Purchaser are included in the securities as to which such registration is being effected, indemnify the Company, each of its directors and officers and its legal counsel, each underwriter, if any, of the Company's securities covered by such a registration statement, each Person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, and each other such Purchaser, each of its officers and directors and each Person controlling such Purchaser within the meaning of Section 15 of 17 the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or 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, and will reimburse the Company, such other Purchasers, such directors, officers, legal counsel, underwriters or control Persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company by an instrument duly executed by such Purchaser and stated to be specifically for use therein; provided, however, that the obligation of such Purchaser hereunder shall be limited to an amount equal to the proceeds received by such Purchaser upon the sale of the Registrable Securities sold in the offering covered by such registration. (c) Each party entitled to indemnification under this Section 2.6 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld). The Indemnified Party may participate in such defense at such party's expense; provided, however, that the Indemnifying Party shall bear the expense of such defense of the Indemnified Party if representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest (as determined in good faith by the Indemnified Party). The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of any liability it may have to an Indemnified Party (i) otherwise than under this Section 2.6 or (ii) under this Section 2.6 except to the extent that the Indemnifying Party forfeits substantive rights as defenses by reason of such failure. 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. (d) The obligations of the Company and Purchasers under this Section 2.6 shall survive the completion of any offering of Registrable Securities under this Agreement. (e) An Indemnifying Party shall make payments within thirty (30) days upon receiving written confirmation from the Indemnified Party of the nature and amount of the expenses to be indemnified. 18 (f) If the indemnification provided for in this Section 2.6 is unavailable or insufficient to hold harmless an Indemnified Party, then each Indemnifying Party shall contribute to the amount paid or payable to such Indemnified Party as a result of the losses, claims, damages or liabilities referred to in this Section 2.6 an amount or additional amount, as the case may be, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party or parties on the one hand and the Indemnified Party on the other in connection with the statements or omissions which resulted in such losses, claims, demands or liabilities as well as any other relevant equitable considerations. The relative fault 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 Indemnifying Party or parties on the one hand or the Indemnified Party on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid to an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 2.6(f) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim which is the subject of this Section 2.6. 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. (g) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Party or any officer, director or controlling Person of such Indemnified Party and shall survive the transfer of securities. 2.7 Information by Purchaser. The Purchaser or Purchasers including Registrable Securities in any registration shall furnish to the Company such information regarding such Purchaser or Purchasers and the distribution proposed by such Purchaser or Purchasers as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Agreement. 2.8 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of securities of the Company to the public without registration, after such time as a public market exists for the Ordinary Shares of the Company, the Company agrees to: (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times after the effective date of the first registration statement under the Securities Act filed by the Company for an offering of its securities to the general public; (b) Use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities 19 Act and the Securities Exchange Act of 1934, as amended (at any time after it has become subject to such reporting requirements); (c) So long as a Purchaser owns any Registrable Securities to furnish to the Purchaser forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after 90 days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Securities Exchange Act of 1934, as amended (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as a Purchaser may reasonably request in availing itself of any rule or regulation of the Commission allowing a Purchaser to sell any such securities without registration. 2.9 Transfer of Registration Rights. The rights to cause the Company to register securities granted to Purchasers under Sections 2.1, 2.2 and 2.5 may be assigned to a transferee or assignee in connection with the transfer or assignment of any of the Registrable Securities held by a Purchaser on the date hereof, provided, that (i) such transfer may otherwise be effected in accordance with applicable securities laws, (ii) the Company is given reasonably prompt written notice of such assignment, (iii) the transferee or assignee agrees in writing to be bound by the obligations of this Agreement, and (iv) the transferee (a) receives at least 25,000 Ordinary Shares or Preferred Shares convertible into 25,000 Ordinary Shares, in each case subject to adjustment for share splits, share dividends or other similar changes in capitalization, or (b) is a general or limited partner of, an Affiliate of or holder of beneficial interests in the transferor. 2.10 General. In the event the Company is obligated to effect a public offering, the Company, the Purchasers and the Stockholders shall cause such meetings to be held, votes cast, resolutions passed, by-laws enacted, documents executed and all acts and things done to effect the public offering on customary and usual terms. 2.11 Other Registration Rights. The Company shall not grant to any Person any registration rights except with the consent of the Supermajority Purchasers, so long as any of the registration rights under this Agreement remain in effect; provided, that the Company may grant registration rights without such consent so long as such rights could not result in a reduction in the number of securities that the Purchasers may include in an underwritten public offering pursuant to this Agreement or otherwise adversely affect the rights of the Purchasers under this Agreement. 2.12 Lock-up Agreements. Each Purchaser and Stockholder hereby agrees that such Purchaser and Stockholder shall not sell any Ordinary Shares (or other securities) of the Company held by such Purchaser and Stockholder (other than those included in the registration) for a period specified by the representative of the underwriters of Ordinary Shares (or other securities) of the Company not to exceed one hundred eighty (180) days following an initial public offering of the Company's securities; provided that all executive officers and directors of the Company enter into similar agreements. 20 2.13 Mergers, Etc. The Company shall not, directly or indirectly, enter into any merger, consolidation or reorganization in which the Company shall not be the surviving corporation unless the proposed surviving corporation shall, prior to such merger, consolidation or reorganization, agree in writing to assume the obligations of the Company under this Agreement, and for that purpose references hereunder to "REGISTRABLE SECURITIES" shall be deemed to be references to the securities which the Purchasers would be entitled to receive in exchange for Registrable Securities under any such merger, consolidation or reorganization, provided, however, that the provisions of this Agreement shall not apply in the event of any merger, consolidation or reorganization in which the Company is not the surviving corporation if the Purchasers are entitled to receive in exchange therefor (i) cash or (ii) securities of the acquiring corporation which may be immediately sold to the public pursuant to an effective registration statement under the Securities Act or pursuant to an exemption therefrom which permits sales without limitation as to volume or the manner of sale on a nationally recognized exchange in the United States or on the Nasdaq National Market. 2.14 Termination. The rights granted pursuant to this Section 2 shall terminate upon the tenth (10th) anniversary of the consummation of a Qualified IPO.

So long as the provisions of this Section 3.1 are in effect, the Company shall require, as a condition precedent to the transfer of any shares covered by this Section 3.1, that the transferee agrees in writing to be bound by, and subject to, the terms and conditions of this Section 3.1 as provided in this Section 3.1 and to ensure that his transferees of the shares shall be likewise bound.

Costs incurred by Purchasers or Stockholders on their own behalf will not be considered costs of the transaction hereunder. 3.3 Termination. The rights granted pursuant to this Section 3 shall terminate immediately prior to the consummation of a Qualified IPO. SECTION 4 PREEMPTIVE RIGHTS 4.1 Right to Purchase. The Company shall only issue New Shares in accordance with the following terms: (a) In the event the Company desires to issue any New Shares, it shall first deliver to each Purchaser a written notice (the "NOTICE OF PROPOSED ISSUANCE") specifying the type and total number of such New Shares which the Company then desires to issue (the "OFFERED NEW SHARES"), all of the terms, including the price, upon which the Company proposes to issue the Offered New Shares, and stating that the Purchasers shall have the right to purchase the Offered New Shares in the manner specified in this Section 4.1 at the price and in accordance with the terms and provisions specified in such Notice of Proposed Issuance. (b) During the thirty (30) consecutive day period commencing on the date all Purchasers have received the Notice of Proposed Issuance (the "THIRTY DAY Period"), the Purchasers shall have the option to purchase all or any portion of the 24 Offered New Shares at the price and terms specified in the Notice of Proposed Issuance. Each Purchaser electing to purchase Offered New Shares must give written notice of its election to the Company during such Thirty Day Period. (c) Each Purchaser shall have the right to purchase that number of the Offered New Shares as shall be equal to the number of the Offered New Shares multiplied by a fraction, the numerator of which shall be the number of Ordinary Shares (calculated on an as converted basis) then owned by such Purchaser and the denominator of which shall be the aggregate number of Ordinary Shares (calculated on an as converted basis) then owned by all of the Purchasers. The amount of such Offered New Shares that each Purchaser is entitled to purchase under this Section 4.1 shall be referred to as its "PROPORTIONATE SHARE." (d) Each Purchaser shall have a right of oversubscription such that if any other Purchaser fails to elect to purchase his or its full Proportionate Share of the Offered New Shares, the other Purchaser(s) shall, among them, have the right to purchase up to the balance of such Offered New Shares not so purchased. The Purchasers may exercise such right of oversubscription by electing to purchase more than their Proportionate Shares of the Offered New Shares by so indicating in their written notice given during the Thirty Day Period. If, as a result thereof, such oversubscriptions exceed the total number of the Offered New Shares available in respect to such oversubscription privilege, the oversubscribing Purchasers shall be cut back with respect to oversubscriptions on a pro rata basis in accordance with their respective Proportionate Shares or as they may otherwise agree among themselves. (e) If all of the Offered New Shares have not been purchased by the Purchasers pursuant to paragraphs (a)-(d) hereof, then the Company shall have the right, subject to Section 4.4 hereof, until the expiration of one-hundred eighty (180) consecutive days commencing on the first day immediately following the expiration of the Thirty Day Period, to issue any remaining Offered New Shares at not less than, and on terms no more favorable to the purchaser than, the price and such other terms as are specified in the Notice of Proposed Issuance. If for any reason such Offered New Shares are not issued within such period and at such price and on such terms, the right to issue in accordance with the Notice of Proposed Issuance shall expire and the provisions of this Agreement shall continue to be applicable to the Offered New Shares. (f) The Purchaser purchasing the greatest percentage of the Offered New Shares shall set the place, time and date for the closing of the purchase of the Offered New Shares, which closing shall not be more than 20 days after the first day immediately following the expiration of the Thirty Day Period. 4.2 Price. The purchase price for the Offered New Shares shall, unless otherwise agreed in writing by the parties to such transaction, be paid on the date of closing in cash, by certified check or by wire transfer of immediately available funds to a bank account designated in advance by the Company. 25 4.3 Closing. At the closing, the Purchasers shall deliver the consideration required by Section 4.2 and the Company shall deliver certificates representing the Offered New Shares. 4.4 Termination. The rights granted pursuant to this Section 4 shall terminate immediately prior to the consummation of a Qualified IPO or a Qualified Private Offering. SECTION 5 RESTRICTIONS ON TRANSFER; CO-SALE 5.1 Restrictions. (a) No Stockholder shall Transfer any Ordinary Shares or other equity securities of the Company except (i) as may be otherwise specifically approved in writing by the Supermajority Purchasers and (ii) if so approved, in accordance with the Purchasers' right of first refusal pursuant to Section 5.2 below and right of co-sale pursuant to Section 5.3 below; and provided, further, that in connection with any Transfer under this Section 5.1, the transferee shall hold such Ordinary Shares or other equity securities of the Company subject to the same restrictions applicable to its transferor and shall agree to be bound by the terms of this Agreement. (b) The provisions of Section 5.1(a) shall not apply to (i) a Transfer to a Family Member of a Stockholder for estate planning purposes or (ii) a Transfer by testamentary or intestate disposition. (c) The rights granted pursuant to Section 5.1(a) shall terminate upon the earliest to occur of (i) the redemption or conversion of all of the outstanding Preferred Shares and (ii) immediately prior to the consummation of a Qualified IPO; provided, however, that the right of approval granted in Section 5.1(a)(i) shall not terminate until the date that is one year after the consummation of a Qualified IPO with respect to any Transfer of equity securities of the Company by any Founder or by Giles Gosselin. 5.2 Right of First Refusal Applicable to Stockholders. (a) If at any time a Stockholder (a "TRANSFERRING STOCKHOLDER") desires to Transfer his Ordinary Shares or other equity securities of the Company to a third party (the "PROPOSED TRANSFEREE") and such Transfer has been approved by the Supermajority Purchasers in accordance with Section 5.1 hereof, then notwithstanding that such approval was obtained, the Transferring Stockholder shall, at least thirty (30) days prior to any Transfer, submit a written offer (the "OFFER") to sell such Ordinary Shares or other securities of the Company (the "OFFERED SHARES") to the Purchasers and the Company on terms and conditions, including price, not less favorable to the Purchasers and the Company than those on which the Transferring Stockholder proposes to Transfer such Offered Shares to the Proposed Transferee, and shall send a copy of the offer to the other Stockholders. The Offer shall disclose the identity of the 26 Proposed Transferee, the Offered Shares proposed to be sold, the total number of Ordinary Shares and other securities of the Company owned by the Transferring Stockholder, the terms and conditions, including price, of the proposed Transfer, and any other material fact relating to the proposed Transfer. The Offer shall further state that the Purchasers or the Company may acquire, in accordance with the provisions of this Agreement, any or all of the Offered Shares for the price and upon the other terms and conditions, including deferred payment (if applicable), set forth therein. (b) Each Purchaser shall have the right to purchase that number of Offered Shares as shall be equal to the number of Offered Shares multiplied by a fraction, the numerator of which shall be the number of Ordinary Shares (calculated on an as converted basis) then owned by such Purchaser and the denominator of which shall be the aggregate number of Ordinary Shares (calculated on an as converted basis) then owned by all of the Purchasers. The amount of such Offered Shares that each Purchaser is entitled to purchase under this Section 5.2 shall be referred to as its "PRO RATA SHARE." If a Purchaser desires to purchase Offered Shares, such Purchaser shall communicate in writing its election to purchase to the Transferring Stockholder and to the Company, which communication shall indicate the number of Offered Shares that the Purchasers elect to purchase and shall be given to the Transferring Stockholder and to the Company within fifteen (15) days of the date the Offer was made (the "15-DAY PERIOD"). (c) Each Purchaser shall have a right of oversubscription such that if any other Purchaser fails to elect to purchase his or its full Pro Rata Share of the Offered Shares, the other Purchaser(s) shall, among them, have the right to purchase up to the balance of such Offered Shares not so purchased. Each Purchaser may exercise such right of oversubscription by electing to purchase more than its Pro Rata Share of the Offered Shares by so indicating in its written notice given during the 15-Day Period. If, as a result thereof, such oversubscriptions exceed the total number of the Offered Shares available in respect to such oversubscription privilege, the oversubscribing Purchasers shall be cut back with respect to oversubscriptions on a pro rata basis in accordance with their respective Pro Rata Shares or as they may otherwise agree among themselves. (d) If the Purchasers do not elect to purchase all of the Offered Shares, then the Company may elect to purchase up to the balance of Offered Shares by communicating in writing to the Transferring Stockholder and the Purchasers the number of Offered Shares that the Company elects to purchase, which notice shall be given to the Transferring Stockholders and the Purchasers within five (5) days of the date the acceptance from the Purchasers was made or if no such acceptance was made, on the fifth day after expiration of the Offer Period. Such communications shall, when taken in conjunction with the Offer, be deemed to constitute valid, legally binding and enforceable agreements for the sale and purchase of such Offered Shares. Sales of the Offered Shares to be sold to the Purchasers and the Company pursuant to this Section 5.2 shall be made on the 30th day following the date the Offer was made (or if such 30th day is not a business day, then on the next succeeding business day). Such sales shall be effected by the Transferring Stockholder's delivery to the Purchasers and Company of a certificate or certificates evidencing the Offered Shares to be purchased by them, together with duly executed instruments of transfer in favor of the Purchasers and Company (or as they may 27 direct), against payment to the Transferring Stockholder of the purchase price therefor by the Purchasers and Company. (e) If the Purchasers and the Company do not purchase all of the Offered Shares and subject to the Co-Sale rights provided for under Section 5.3 below, any remaining Offered Shares may be sold by the Transferring Stockholder at any time within 120 days after the date the Offer was made. Any such sale shall be to the Proposed Transferee or another Stockholder, at not less than the price and upon other terms and conditions, if any, not more favorable to the Proposed Transferee or other Stockholder than those specified in the Offer. Any Offered Shares not sold within such 120-day period shall continue to be subject to the requirements of a prior offer pursuant to this Section 5. (f) The rights granted pursuant to this Section 5.2 shall not apply to (i) a Transfer to a Family Member of a Stockholder for estate planning purposes, (ii) a Transfer by testamentary or intestate disposition. (g) The rights granted pursuant to this Section 5.2 shall terminate immediately prior to the consummation of a Qualified IPO or a Qualified Private Offering. (h) In connection with any sale pursuant to this Section 5.2, the transferee shall hold such Ordinary Shares or other equity securities of the Company subject to the same restrictions applicable to the Stockholders and shall agree to be bound by the terms of this Agreement. 5.3 Right of Co-Sale Applicable to Stockholders. (a) After receiving the Offer delivered pursuant to Section 5.2(a) above, the Purchasers (each a "CO-SALE PARTICIPANT") may, in lieu of exercising any rights of first refusal they may have under Section 5.2, elect to participate in the contemplated Transfer by delivering written notice to the Transferring Stockholder within fifteen days after delivery of the Offer. Each Co-Sale Participant shall be entitled to sell in the contemplated Transfer, at the same price and on the same terms, a number of Ordinary Shares or other equity securities of the Company (on an Ordinary Share equivalent basis) equal to the product of (i) the quotient determined by dividing (A) the number of outstanding Ordinary Shares (calculated on an as converted basis) owned by such Co-Sale Participant by (B) the aggregate number of outstanding Ordinary Shares owned or held by the Transferring Stockholder and all of the Co-Sale Participants (calculated on an as converted basis) and (ii) the number of Offered Shares (on an Ordinary Share equivalent basis) to be sold in the contemplated Transfer. (b) The provisions of Section 5.3(a) shall not apply to (i) a Transfer to a Family Member of a Stockholder for estate planning purposes or (iii) a Transfer by testamentary or intestate disposition. 28 (c) The rights granted pursuant to this Section 5.3 shall terminate immediately prior to the consummation of a Qualified IPO or a Qualified Private Offering. (d) In connection with any sale pursuant to this Section 5.3, the transferee shall hold such Ordinary Shares or other equity securities of the Company subject to the same restrictions applicable to the Stockholders and shall agree to be bound by the terms of this Agreement. 5.4 Right of First Refusal Applicable to Purchasers. For purposes of this Section 5.4 only, the term "Purchasers" shall not include the holders of Series C Preferred Shares (or Ordinary Shares issued upon conversion thereof) with respect to any such shares, provided that: (i) such holders shall be sent a copy of any Preferred Offer (as defined herein) for purposes associated with their rights under Section 5.5 hereof and (ii) to the extent holders of Series C Preferred Shares are intending to transfer such Series C Shares (or the Ordinary Shares into which any Series C Preferred Shares have been converted) to a Competitor, other than any Person who is a Purchaser or Stockholder immediately after the Closing Date, the provisions set forth below will be applicable to such intended transfer. (a) If at any time a Purchaser (a "TRANSFERRING PURCHASER") desires to transfer its Preferred Shares (or the Ordinary Shares into which they have been converted) to a third party (the "PROPOSED BUYER"), then the Transferring Purchaser shall, at least ten (10) days prior to any Transfer, submit a written offer (the "PREFERRED OFFER") to sell such Preferred Shares or the Ordinary Shares into which they are converted (the "OFFERED SECURITIES") to the other Purchasers on terms and conditions, including price, not less favorable to such Purchasers than those on which the Transferring Purchaser proposes to transfer such Offered Securities to the Proposed Buyer. The Preferred Offer shall disclose the identity of the Proposed Buyer, the Offered Securities proposed to be sold, the terms and conditions, including price, of the Proposed Transfer, and any other material fact relating to the proposed Transfer. The Preferred Offer shall further state that the Purchasers may acquire, in accordance with the provisions of this Agreement, all of the Offered Securities for the price and upon the other terms and conditions, including deferred payment (if applicable), set forth therein. (b) Each Purchaser shall have the right to purchase that number of Offered Securities as shall be equal to the number of Offered Securities multiplied by a fraction, the numerator of which shall be the number of Ordinary Shares (calculated on an as converted basis) then owned by such Purchaser and the denominator of which shall be the aggregate number of Ordinary Shares (calculated on an as converted basis) then owned by all of the Purchasers other than the Transferring Purchaser. The amount of such Offered Securities that each Purchaser is entitled to purchase under this Section 5.4 shall be referred to as its "PRO RATA PORTION." If a Purchaser desires to purchase Offered Securities, such Purchaser shall communicate in writing its election to purchase to the Transferring Purchaser, which communication shall indicate the number of Offered Securities that the Purchaser elects to purchase and shall be given to the Transferring Purchaser within ten (10) days of the date the Offer was made (the "10-DAY PERIOD"). 29 (c) Each Purchaser shall have a right of oversubscription such that if any other Purchaser fails to elect to purchase his or its full Pro Rata Portion of the Offered Securities, the other Purchaser(s) shall, among them, have the right to purchase up to the balance of such Offered Securities not so purchased. Each Purchaser may exercise such right of oversubscription by electing to purchase more than its Pro Rata Portion of the Offered Securities by so indicating in its written notice given during the 10-Day Period. If, as a result thereof, such oversubscriptions exceed the total number of the Offered Securities available in respect to such oversubscription privilege, the oversubscribing Purchasers shall be cut back with respect to oversubscriptions on a pro rata basis in accordance with their respective Pro Rata Portions or as they may otherwise agree among themselves. (d) The communications described above shall, when taken in conjunction with the Preferred Offer, be deemed to constitute valid, legally binding and enforceable agreements for the sale and purchase of such Offered Securities. Sales of the Offered Securities to be sold to the other Purchasers pursuant to this Section 5.4 shall be made on the 20th day following the date the Preferred Offer was made (or if such 20th day is not a business day, then on the next succeeding business day). Such sales shall be effected by the Transferring Purchaser's delivery to the other Purchasers of a certificate or certificates evidencing the Offered Securities to be purchased by them, together with duly executed instruments of transfer in favor of such Purchasers (or as they may direct), against payment to the Transferring Purchaser of the purchase price therefor by such Purchasers. (e) If the Purchasers other than the Transferring Purchaser do not agree to purchase all of the Offered Securities and subject to the Co-Sale rights provided for under Section 5.5 below, the Offered Securities may be sold by the Transferring Purchaser at any time within 120 days after the date the Preferred Offer was made. Any such sale shall be to the Proposed Buyer, at not less than the price and upon other terms and conditions, if any, not more favorable to the Proposed Buyer than those specified in the Preferred Offer. Any Offered Securities not sold within such 120-day period shall continue to be subject to the requirements of a prior offer pursuant to this Section 5.4. (f) The rights granted pursuant to this Section 5.4 shall not apply to a Transfer to an Affiliate. (g) The rights granted pursuant to this Section 5.4 shall terminate immediately prior to the consummation of a Qualified IPO or a Qualified Private Offering. (h) In connection with any sale pursuant to this Section 5.4, the transferee shall hold such Preferred Shares subject to the same restrictions applicable to the Purchasers and shall agree to be bound by the terms of this Agreement. 5.5 Right of Co-Sale Applicable to the Purchasers and Stockholders. For the avoidance of doubt, for purposes of this Section 5.5, the term "PURCHASERS" shall 30 include holders of Series C Preferred Shares (or Ordinary Shares issued upon conversion thereof). (a) If one or more Purchasers or Stockholders propose to sell Offered Securities and/or Offered Shares constituting more than twenty-five percent (25%) of the Company's then outstanding Ordinary Shares (calculated on an as converted basis), the Purchasers (each a "CO-SELLER") may, in lieu of exercising any rights of first refusal they may have under Section 5.4, elect to participate in the contemplated Transfer by delivering written notice to the Transferring Purchaser and/or Transferring Stockholder within fifteen days after delivery of the Preferred Offer. Each Co-Seller shall be entitled to sell in the contemplated Transfer, at the same price and on the same terms, a number of Preferred Shares or other equity securities of the Company (on an Ordinary Share equivalent basis) equal to the product of (i) the quotient determined by dividing (A) the number of outstanding Ordinary Shares (calculated on an as converted basis) owned by such Co-Seller by (B) the aggregate number of outstanding Ordinary Shares owned or held by the Transferring Purchaser and/or Transferring Stockholder and all of the Co-Sellers (calculated on an as converted basis) and (ii) the number of Offered Securities and Offered Shares (on an Ordinary Share equivalent basis) to be sold in the contemplated Transfer.

(c) The rights granted pursuant to this Section 5.5 shall terminate immediately prior to the consummation of a Qualified IPO or a Qualified Private Offering.
