(a)Requests for Registration. Subject to the terms and conditions of thisSection 2, beginning on the date that is nine (9) months from the date of this Agreement and from time to time thereafter, the holders of at least a majority of the Warburg Registrable Securities (the “Warburg Majority Holders”) may request registration under the Securities Act of all or any portion of their Registrable Securities on FormsS-3 orF-3, as applicable, or any similar short-form registration (“Short-Form Registrations”), or, if such forms are not available, then on FormsS-1 orF-1, as applicable, or any similar long-form registration (“Long-Form Registrations”);provided that, after the 9 month anniversary and prior to the one year anniversary of the date of this Agreement, Warburg shall sell no more than the number of Registrable Securities that is 20% of the number of Ordinary Shares outstanding on the date hereof pursuant to a Demand Registration (as defined below). All registrations requested pursuant to thisSection 2(a) are referred to herein as “Demand Registrations.” Each request for a Demand Registration (a “Demand Request”) shall specify (i) the number of Registrable Securities requested to be registered and (ii) the anticipated method or methods of distribution. Within three (3) business days after receipt of any Demand Request, the Company shall give written notice of such Demand Registration (which shall specify the intended method of distribution of such Registrable Securities) to all other Shareholders (a “Company Notice”) and, subject to the terms ofSection 2(d) hereof, shall include in such registration (and in all related registrations and qualifications under state blue sky laws or in compliance with other registration requirements and in any related underwriting) all Registrable Securities with respect to which the Company has received written requests for inclusion therein within ten (10) days after the receipt of the Company Notice. The Warburg Majority Holders shall be entitled to request three (3) Demand Registrations (whether Long-Form Registrations or Short-Form Registrations) and Marketed Underwritten Shelf Offerings in the aggregate;provided, however, that the first Marketed Underwritten Shelf Offering initiated by the Warburg Majority Holders from any Shelf Registration Statement previously requested by the Warburg Majority Holders, shall not be deemed to be, solely for purposes of the limitation in this sentence, a Marketed Underwritten Shelf Offering. Notwithstanding the foregoing, if the Warburg Majority Holders wish to engage in an underwritten block trade off of a Shelf Registration Statement (as defined below) (either through filing an automatic Shelf Registration Statement or through a take-down from an already existing Shelf Registration Statement) and either the Convertible Notes have ceased to remain outstanding or the holders of the Convertible Notes no longer have piggyback rights pursuant to the terms

3

thereof, then notwithstanding the foregoing time periods, the Warburg Majority Holders only need to notify the Company of the block trade Demand Request two (2) business days prior to the day such offering is to commence (unless a longer period is agreed to by the Warburg Majority Holders wishing to engage in the underwritten block trade) and the Company shall not be required to notify any other Investors of such Demand Request and such other Investors shall have no right to piggyback on such Demand Request and the Company shall as expeditiously as possible use its reasonable best efforts to facilitate such offering (which may close as early as two (2) business days after the date it commences); provided, however, that the Warburg Majority Holders making such request shall use commercially reasonable efforts to work with the Company and the underwriters prior to making such request to facilitate preparation of the registration statement, prospectus and other offering documentation related to the underwritten block trade. A registration shall not count as one (1) of the permitted Demand Registrations until it has become effective, and unless the holders of Warburg Registrable Securities (A) are able to register and sell at least 75% of the Warburg Registrable Securities requested to be included in such registration; or (B) register and sell at least 50% of the Warburg Registrable Securities then outstanding in such registration.

(b)Shelf Registrations. Subject to the other applicable provisions of this Agreement, the Company shall, at the request of the Warburg Majority Holders, prepare and file within twenty four (24) months after the date hereof a registration statement covering the sale or distribution from time to time by holders of Registrable Securities, on a delayed or continuous basis pursuant to Rule 415 of the Securities Act, of all of the Registrable Securities on FormF-3 or FormS-3 (except if the Company is not then eligible to register for resale the Registrable Securities on FormF-3 or FormS-3, then such registration shall be on another appropriate form and shall provide for the registration of such Registrable Securities for resale by the holders of the Warburg Registrable Securities in accordance with any reasonable method of distribution elected by the Warburg Majority Holders) (a “Shelf Registration Statement”) and shall use its best efforts to cause such Shelf Registration Statement to be declared effective as promptly as practicable. On and following the date that is the24-month anniversary of the date hereof, if a Shelf Registration Statement has been requested by the Warburg Majority Holders, the Company shall, subject to the other applicable provisions of this Agreement, use its reasonable best efforts to cause the Shelf Registration Statement to be continuously effective and usable until such time as there are no longer any Warburg Registrable Securities. The Company shall, prior to the expiration of any such Shelf Registration Statement, file a new Shelf Registration Statement covering such Warburg Registrable Securities and shall thereafter use its best efforts to cause to be declared effective as promptly as practical, such new Shelf Registration Statement. The Company shall supplement and amend any Shelf Registration Statement if required by the Securities Act or the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement. Subject to the other applicable provisions of this Agreement, at any time that any Shelf Registration Statement is effective, if a holder of Warburg Registrable Securities delivers a notice to the Company stating that it intends to effect a sale or distribution of all or part of its Registrable Securities included by it on any Shelf Registration Statement (a “Shelf Offering”) and stating the number of the Registrable Securities to be included in such Shelf Offering, then the Company shall amend, subject to the other applicable provisions of this Agreement, or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be sold and distributed pursuant to the Shelf Offering.

(c)Priority on Demand Registrations. The Company shall not include in any Demand Registration any securities that are not Warburg Registrable Securities (other than Ordinary Shares held by holders of Convertible Notes for so long as the holders of the Convertible Notes have piggyback rights pursuant to the terms thereof) without the prior written consent of the Warburg Majority Holders included in such Demand Registration. If a Demand Registration is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range specified in the Demand Request pursuant toSection 2(a) and without adversely affecting the marketability of the offering, then the Company shall include in such Demand Registration (A) first, the number of Warburg Registrable Securities requested to be included in such registration prorata, if necessary, among the holders of Warburg Registrable Securities based on the

4

number of Warburg Registrable Securities owned by each such Shareholder and (B) second, any other securities of the Company requested to be included in such registration prorata, if necessary, on the basis of the number of such other securities requested to be included therein by each such Shareholder;provided, that Registrable Securities held by employees of the Company shall be included in such Demand Registration only if, and only to the extent that, the managing underwriters advise the Company in writing that in their opinion such Registrable Securities can be sold therein without adversely affecting the marketability of such offering.

(d)Restrictions on Registrations. The Company shall not be obligated to effect, (i) any Long-Form Registration during the period (A) beginning 60 days before the Company’s good faith estimate of the date of filing of, and ending on a date that is 90 days after the effective date of, a Company-initiated registration (other than Registration Statement on FormsS-8,S-4 orF-4, as applicable, or any successor form or form for similar registration purposes), except to the extent that Section 3(b) or 3(c) hereof was applied to limit the Registrable Securities included in such Company-initiated registration in which case the period during which the Company shall not be obligated to effect a Long-Form Registration shall be the period beginning 30 days before the Company’s good faith estimate of the date of filing of, and ending on a date that is 30 days after the effective date of, a Company-initiated registration or (B) of 90 days after the effective date of the previous Long-Form Registration or (ii) any Short-Form Registration during the period (A) beginning 45 days before the Company’s good faith estimate of the date of filing of, and ending on a date that is 60 days after the effective date of, a Company-initiated registration (other than Registration Statement on FormsS-8,S-4 orF-4, as applicable, or any successor form or form for similar registration purposes), except to the extent that Section 3(b) or 3(c) hereof was applied to limit the Registrable Securities included in such Company-initiated registration in which case the period during which the Company shall not be obligated to effect a Short-Form Registration shall be the period beginning 30 days before the Company’s good faith estimate of the date of filing of, and ending on a date that is 30 days after the effective date of, a Company-initiated registration or (B) of 60 days after the effective date of the previous Long-Form Registration, in each case unless the Company otherwise agrees in writing.

The Company may postpone for no more than 90 days in each360-day period the filing or the effectiveness of a Registration Statement for a Demand Registration if the Board (in its reasonable good faith judgment) determines that such Demand Registration might reasonably be expected to (i) materially interfere with abona fide significant acquisition, corporate reorganization, or other similar transaction involving the Company, in each case that the Company is currently and actively pursuing, disclosure of which would reasonably be expected to be required in such registration statement (but would not be required if such registration statement were not filed or were not effective); or (ii) require premature disclosure of material nonpublic information that would materially and adversely impact the Company and that would not otherwise be required to be disclosed at that time;provided that, in such event, the Warburg Majority Holders requesting such Demand Registration will be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration will not count as a Demand Registration and the Company will pay all Registration Expenses in connection with such requested registration;provided further that the Company shall not register any securities for its own account or that of any other equityholder during such period.

(e)Selection of Underwriters. The Warburg Majority Holders included in any Demand Registration shall have the right to select the investment banker(s) and manager(s) to administer the offering;provided, that such selection shall require the approval of the Company which approval shall not be unreasonably withheld, delayed or conditioned.

(f)Other Registration Rights. Other than the Convertible Notes, the Company represents and warrants that it is not a party to, or otherwise subject to, any other agreement granting registration rights to any other Person with respect to any securities of the Company. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company to register any equity securities of the Company having priority over the Registrable Securities with respect to inclusion of such equity securities in any registration without the prior written consent of the Warburg Majority Holders.

In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Indemnified Parties.

(b) In connection with any Registration Statement in which a Shareholder is participating, each such Shareholder shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement and, to the extent permitted by law, shall indemnify the Company, its directors, officers and employees, and each Person who controls the Company (within the meaning of the Securities Act) against any Losses arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement, or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished in writing by such Shareholder;provided that the obligation to indemnify shall be individual, not joint and several, for each Shareholder and shall be limited to the net amount of proceeds received by such Shareholder from the sale of Registrable Securities pursuant to such Registration Statement.

(c) Any Indemnified Party shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Indemnified Party’s right to indemnification hereunder to the extent such failure has not actually prejudiced the indemnifying party) and (ii) unless in such Indemnified Party’s reasonable judgment a conflict of interest between such Indemnified Party and such indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the Indemnified Party without its prior written consent, such consent not to be unreasonably withheld;provided,however, that withholding consent to a settlement (i) that does not include as an unconditional term thereof the giving by the claimant or the plaintiff a complete release of the Indemnified Party from all liability in respect of such claim or litigation or (ii) the effect of which is to permit any injunction, declaratory judgment, other order or other equitable relief to be entered, directly or indirectly, against the indemnifying party shall not be considered unreasonable. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one (1) counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any Indemnified Party a conflict of interest may exist between such Indemnified Party and any other of such Indemnified Parties with respect to such claim.

(d) The indemnification and contribution 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 and shall survive the transfer of securities. The Company also agrees to make such provisions, as are reasonably requested by an Indemnified Party, for contribution to such party in the event the Company’s indemnification is unavailable for any reason.

8.Participation in Underwritten Registrations.

No Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements (including pursuant to any over-allotment or “green

10

shoe” option requested by the underwriters;provided that no Shareholder shall be required to sell more than the number of Registrable Securities such Shareholder has requested to include in such underwritten registration) and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements;provided that no Shareholder included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such Shareholder and such Shareholder’s intended method of distribution and regarding such Shareholders title to the Registrable Securities being offered and sold) or to undertake any indemnification obligations to the Company or the underwriters with respect thereto, except as otherwise provided inSection 7 hereof.

9.Rule 144 Reporting.

With a view to making available to the Shareholders the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use, at its own expense, its reasonable best efforts to:

(a) make and keep current public information available, within the meaning of Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the date of this Agreement;

(b) file with the SEC, in a timely manner, all reports and other documents required of the Company under the Securities Act and Exchange Act; and

(c) for so long as any party hereto owns any Registrable Securities, furnish to such Person forthwith upon request, a written statement by the Company as to its compliance with the reporting requirements of Rule 144, the Securities Act and the Exchange Act; a copy of the most recent annual or quarterly report of the Company; and such other reports and documents as such Person may reasonably request in availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration.

10.Termination. The rights of any particular Shareholder to cause the Company to register securities underSection 2shall terminate with respect to such Shareholder upon the date upon which such Shareholder no longer holds any Registrable Securities.

11.Miscellaneous.

(a)No Inconsistent Agreements. The Company shall not hereafter enter into any agreement with respect to its securities that is inconsistent with or violates the rights granted to the Shareholders in this Agreement.

(b)Remedies. Any Person having rights under any provision of this Agreement shall be entitled to enforce such rights specifically to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that, in addition to any other rights and remedies existing in its favor, any party shall be entitled to specific performance and/or other injunctive relief from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce or prevent violation of the provisions of this Agreement.

(c)Amendments and Waivers. Except as otherwise provided herein, the provisions of this Agreement may be amended or waived in a writing executed and delivered by the Company and the Warburg Majority Holders;provided, that any such amendment or waiver that materially and adversely affects any Investor in a manner that does not similarly affect all similarly situated Investors cannot be effected without the consent of such Investor. The failure of any party to enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

11

(d)Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. In addition, whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of purchasers or Shareholders are also for the benefit of, and enforceable by, any subsequent Shareholder to whom such rights are assigned by the transferring Shareholder and who signs a joinder to this Agreement. The rights and obligations of Warburg pursuant to this Agreement may be assigned to third parties provided however that (i) any such assignee acquires no less than 10% of the then outstanding equity securities of the Company, (ii) the number of Demand Registrations to which the Investors are entitled hereunder shall not be increased as a result of such assignment (i.e. a Demand Registration by any assignee shall count as one of Investor’s three Demand Registrations per Section 2(a) above), and (iii) without the prior written consent of the Company, such rights and obligations may not be assigned to any Person that is or would reasonably be viewed asa competitor of the Company (it being understood that, following any such permitted assignment pursuant to thisSection 11(d), the assignee shall promptly deliver to the Company a joinder in substantially the form attached hereto asExhibit A duly executed by such assignee and all references to Warburg Majority Holders and Warburg Registrable Securities shall include any such assignee and such assignee’s Registrable Securities).

(e)Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that in such case the parties shall negotiate in good faith to replace such provision with a new provision which is not illegal, unenforceable or void, as long as such new provision does not materially change the economic benefits of this Agreement to the parties.

(f)Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument.

(g)Headings. The headings of this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

(h)Governing Law; Jurisdiction. This Agreement and all claims, controversies and causes of action arising out of or relating to this Agreement, whether sounding in contract, tort, or statute, shall be governed by and construed under the laws of the State of Israel applicable to contracts made and to be performed entirely within the State of Israel.

Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.
