Unless earlier terminated by the written consent of Pubco (in its sole and absolute discretion), this Agreement shall terminate automatically and shall have no further force or effect (a) one hundred eighty (180) days following the Closing Date with respect to Section 2.3 or (b) as of the Expiration Time with respect to the other provisions in this Agreement. Upon termination of this Agreement, no Party shall have any further obligations or liabilities under this Agreement; provided, however, that (i) nothing set forth in this Section 7 shall relieve any Party from liability for fraud or any willful breach of this Agreement prior to termination hereof and (ii) the provisions of this Section 7 and Section 9 shall survive any termination of this Agreement. In the event that the Merger Agreement is terminated, this Agreement shall automatically terminate.

8. Reliance. The Shareholder understands and acknowledges that that the Company is entering into the Merger Agreement in reliance upon the Shareholder’s execution, delivery and performance of this Agreement.

9. Miscellaneous.

9.1 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

9.2 Binding Effect and Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party (whether by operation of Law or otherwise) without the prior written consent of the other Party. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective permitted successors and assigns. Any assignment in violation of this Section 9.2 shall be void.

9.3 Amendments and Waivers. Any provision of this Agreement may be amended, modified, supplemented or waived if, but only if, such amendment, modification, supplement or waiver is in writing and is signed, in the case of an amendment, modification or supplement by each Party to this Agreement or, in the case of a waiver, by each Party against whom the waiver is to be effective. No failure or delay by any Party to assert any of its rights under this Agreement or otherwise shall constitute a waiver of such rights.

9.4 Specific Performance; Injunctive Relief. The Parties agree that irreparable injury, for which monetary damages (even if available) would not be an adequate remedy, will occur in the event that any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached. Accordingly, it is agreed that each Party shall be entitled to an injunction or injunctions to prevent or remedy any breaches or threatened breaches of this Agreement by any other Party, a decree or order of specific performance specifically enforcing the terms and provisions of this Agreement and any further equitable relief, in each case in accordance with Section 9.6, this being in addition to any other remedy to which such Party is entitled under the terms of this Agreement at law or in equity. The Parties’ rights in this Section 9.4 are an integral part of the transactions contemplated hereby and each Party hereby waives any objections to any remedy referred to in this Section 9.4 (including any objection on the basis that there is an adequate remedy at Law or that an award of such remedy is not an appropriate remedy for any reason at Law or equity). For avoidance of doubt, each Party agrees that there is not an adequate remedy at Law for a breach of this Agreement by any Party. In the event any Party seeks any remedy referred to in this Section 9.4, such Party shall not be required to obtain, furnish, post or provide any bond or other security in connection with or as a condition to obtaining any such remedy.

9.5 Notices. All notices, consents and other communications hereunder shall be in writing and shall be given in the manner described in Section 9.4 of the Merger Agreement, addressed as follows: (i) if to the Company, to its address or email address set forth in Section 9.4 of the Merger Agreement, and (ii) if to the Shareholder, to the Shareholder’s address or email address set forth on a signature page hereto, or to such other address or email address as such Party may hereafter specify for the purpose by notice to each other Party hereto.

9.6 Applicable Law; Jurisdiction of Disputes. This Agreement and any dispute, controversy or claim arising out of, relating to or in connection with this Agreement shall be governed by and construed and enforced in accordance with the Laws of the State of Delaware, USA, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or otherwise) that would cause the application of the Laws of any other jurisdiction; except that provisions related to the internal affairs of the Company, the fiduciary and other duties of its directors, the procedures for implementing, and effects of, the Pubco Merger, and all other provisions of, or transactions contemplated by, this Agreement that are expressly or otherwise required to be governed by the Laws of the State of Israel shall be governed by such Laws. Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks jurisdiction, the Federal court of the United States of America sitting in Delaware, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby or for recognition or enforcement of any judgment relating thereto, and each of the Parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding, except in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks jurisdiction, the Federal court of the United States of America sitting in Delaware, and any appellate court from any thereof; (ii) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks jurisdiction, the Federal court of the United States of America sitting in Delaware, and any appellate court from any thereof; (iii) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any such action or proceeding in such courts; and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in such courts. Notwithstanding the foregoing, with respect to any action or proceeding arising out of this Agreement or any of the transactions contemplated hereby that primarily relate to Israeli Law matters, each of the parties hereto (x) consents to submit itself to the personal jurisdiction of the courts of Tel-Aviv, Israel, and (y) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court. Each of the Parties agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law. Each Party irrevocably consents to service of process inside or outside the territorial jurisdiction of the courts referred to in this Section 9.6 in the manner provided for notices in Section 9.5. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by applicable Law.

9.7 Waiver of Jury Trial. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.7.

9.8 Entire Agreement. This Agreement, together with the Merger Agreement contains the entire understanding of the Parties in respect of the subject matter hereof, and supersedes all prior negotiations and understandings between the Parties with respect to such subject matter.

9.9 Counterparts. This Agreement may be executed manually or by other electronic transmission by the Parties, in any number of counterparts, each of which shall be considered one and the same agreement and shall become effective when a counterpart hereof shall have been signed by each of the Parties and delivered to the other Parties. The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic transmission in .pdf or DocuSign format shall be sufficient to bind the Parties to the terms and conditions of this Agreement.

9.10 Interpretation. When a reference is made in this Agreement to sections, such reference shall be to a section of this Agreement, unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation.” As used in this Agreement, the term “affiliates” shall have the meaning set forth in Rule 12b-2 of the Exchange Act; provided, that no direct or indirect portfolio companies (as such term is understood in the private equity industry) or investments of or affiliated with the Shareholder of any of its Affiliates shall be deemed or treated as an Affiliate of the Shareholder. The word “extent” and the phrase “to the extent” when used in this Agreement shall mean the degree to which a subject or other things extends, and such word or phrase shall not merely mean “if.” The term “or” is not exclusive, and shall be interpreted as “and/or.” The phrases “the date of this Agreement,” “the date hereof,” “of even date herewith” and terms of similar import, shall be deemed to refer to the date set forth in the preamble to this Agreement. The headings set forth in this Agreement or any schedule delivered pursuant to this Agreement are for convenience of reference purposes only and shall not affect or be deemed to affect in any way the meaning or interpretation of this Agreement or such schedule or any term or provision hereof or thereof. All references herein to the Subsidiaries of a Person shall be deemed to include all direct and indirect Subsidiaries of such Person, unless otherwise indicated or the context otherwise requires. A reference to any specific Law or to any provision of any Law, whether or not followed by the phrase “as amended,” includes any amendment to, and any modification, re-enactment or successor thereof, any legislative provision substituted therefor and all rules, regulations and statutory instruments issued thereunder or pursuant thereto, except that, for purposes of any representations and warranties in this Agreement that are made as a specific date, references to any specific Law will be deemed to refer to such legislation or provision (and all rules, regulations and statutory instruments issued thereunder or pursuant thereto) as of such date. The Parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

9.11 Capacity as Shareholder. No person executing this Agreement who is or becomes an officer or director of the Company makes any agreement or understanding herein in his or her capacity as such officer or director. The Shareholder signs solely in his, her or its capacity as the record and beneficial owner of the Covered Shares. Nothing herein shall limit or affect any actions taken by a Shareholder or any officer, director, employee, affiliate or representative of a Shareholder solely in his or her capacity as an officer or director of the Company, including without limitation, exercising his or her fiduciary duties in connection thereto.

9.12 Adjustments. After the date of this Agreement and prior to the termination of this Agreement in accordance with Section 7, in the event of an Adjustment, the term “Covered Shares” shall be deemed to refer to and include any stock (or share) and any securities into which or for which any or all of such stock (or share) and securities may be changed or exchanged or which are received in such Adjustment.

9.13 Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by the Party incurring such cost or expense.

9.14 No Agreement Until Executed. This Agreement shall not be effective unless and until (i) the Merger Agreement is executed and delivered by all parties thereto and (ii) this Agreement is executed and delivered by all Parties.

9.15 Further Assurances. The Shareholder will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use the Shareholder’s reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Law, to perform the Shareholder’s obligations under this Agreement.

9.16 No Third Party Beneficiaries. Nothing in this Agreement shall confer any rights upon any Person other than the Parties and each such Party’s respective heirs, successors and permitted assigns, except as otherwise set forth herein.

9.17 Non-Survival of Representations and Warranties. The respective representations and warranties of the Shareholder and the Company contained herein shall not survive the closing of the transactions contemplated hereby and by the Merger Agreement.

9.18 Non-Recourse. Notwithstanding anything herein to the contrary, this Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or to the extent related to this Agreement may only be brought against the entities that are expressly named as Parties hereto and their respective successors and assigns. Except as set forth in the immediately preceding sentence, no past, present or future director, officer, manager, employee, incorporator, member, partner, stockholder, equityholder, controlling person, Affiliate, agent, attorney, advisor or representative of any Party hereto, and no past, present or future director, officer, manager, employee, incorporator, member, partner, stockholder, equityholder, controlling person, Affiliate, agent, attorney, advisor or representative of any of the foregoing (each, a “Non-Recourse Party”) shall have any liability for any obligations or liabilities of any Party hereto under this Agreement (whether in tort, contract or otherwise). The Parties acknowledge and agree that the Non-Recourse Parties are third party beneficiaries of this Section 9.18, each of whom may enforce the provisions thereof.
