Each agreement or other instrument (however characterized or described) to which the Company is a party or by which it is or may be bound or affected and (i) that is referred to in the Registration Statement, the Pricing Disclosure Package and the Prospectus, or (ii) is material to the Company’s business, has been duly authorized and validly executed by the Company, is in full force and effect in all material respects and is enforceable against the Company and, to the Company’s knowledge, the other parties thereto, in accordance with its terms, except (x) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally, (y) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws, and (z) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought. None of such agreements or instruments has been assigned by the Company, and neither the Company nor, to the Company’s knowledge, any other party is in default thereunder and, to the Company’s knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder, except for any such default that would not have or reasonably be expected to result in a material adverse change in the financial position or results of operations of the Company, nor any change or development that, singularly or in the aggregate, would involve a material adverse change, in or affecting the condition (financial or otherwise), results of operations, prospects, business or assets of the Company (a “Material Adverse Change”).

No indemnification provided for in Section 5(a) or 5(b) shall be available to any party who shall fail to give notice as provided in this Section 5(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was prejudiced by the failure to give such notice but the omission so to notify such indemnifying party of any such action, suit or proceeding shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than under this Section. In case any such action, suit or proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and the approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized in writing by the indemnifying parties, (ii) the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it which are different from or in addition to those available to the indemnifying party (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iii) the indemnifying parties shall not have employed counsel to assume the defense of such action within a reasonable time after notice of the commencement thereof, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying parties. An indemnifying party shall not be liable for any settlement of any action, suit, and proceeding or claim effected without its written consent, which consent shall not be unreasonably withheld or delayed.

6. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 5(a) or 5(b) is due in accordance with its terms but for any reason is unavailable to or insufficient to hold harmless an indemnified party in respect to any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate losses, liabilities, claims, damages and expenses (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting any contribution received by any person entitled hereunder to contribution from any person who may be liable for contribution) incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or, if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 6, no Underwriter (except as may be provided in the Agreement Among Underwriters) shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Securities purchased by such Underwriter. 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. For purposes of this Section 6, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 6, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 6. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent. The Underwriters’ obligations to contribute pursuant to this Section 6 are several in proportion to their respective underwriting commitments and not joint.

7. Termination.

(a) This Agreement may be terminated with respect to the Securities to be purchased on the Closing Date or an Option Closing Date by the Representative by notifying the Company at any time at or before the Closing Date or such Option Closing Date in the absolute discretion of the Representative if: (i) there has occurred any material adverse change in the securities markets or any event, act or occurrence that has materially disrupted, or in the reasonable judgment of the Representative, will in the near future materially disrupt, the securities markets or there shall be such a material adverse change in general financial, political or economic conditions or the effect of international conditions on the financial markets in the United States is such as to make it, in the reasonable judgment of the Representative, inadvisable or impracticable to market the Securities or enforce contracts for the sale of the Securities; (ii) there has occurred any outbreak or material escalation of hostilities or acts of terrorism or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in the reasonable judgment of the Representative, inadvisable or impracticable to market the Securities or enforce contracts for the sale of the Securities; (iii) trading in the Ordinary Shares or any securities of the Company has been suspended or materially limited by the Commission or trading generally on the New York Stock Exchange, Inc. or the NASDAQ has been suspended or materially limited, or minimum or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities have been required, by any of said exchanges or by such system or by order of the Commission, FINRA, or any other governmental or regulatory authority; or (iv) a banking moratorium has been declared by any state or Federal authority; or (v) in the reasonable judgment of the Representative, there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any Material Adverse Change.

(b) If this Agreement is terminated pursuant to any of its provisions, the Company shall not be under any liability to any Underwriter, and no Underwriter shall be under any liability to the Company, except that (y) if this Agreement is terminated by the Representative or the Underwriters because of any failure, refusal or inability on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company will reimburse the Underwriters for all reasonable, documented expenses (including the reasonable fees and disbursements of their counsel) incurred by them in connection with the proposed purchase and sale of the Securities or in contemplation of performing their obligations hereunder and (z) no Underwriter who shall have failed or refused to purchase the Securities agreed to be purchased by it under this Agreement, without some reason sufficient hereunder to justify cancellation or termination of its obligations under this Agreement, shall be relieved of liability to the Company or to the other Underwriters for damages occasioned by its failure or refusal.

8. Substitution of Underwriters. If any Underwriter shall default in its obligation to purchase on the Closing Date or an Option Closing Date the Securities agreed to be purchased hereunder, the Representative shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase such Securities on the terms contained herein. If, however, the Representative shall not have completed such arrangements within such 36-hour period, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Underwriters to purchase such Securities on such terms. If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of Securities which remains unpurchased on the Closing Date or such Option Closing Date does not exceed one-eleventh of the aggregate number of all the Securities that all the Underwriters are obligated to purchase on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Securities which such Underwriter agreed to purchase hereunder at such date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default. In any such case, either the Representative or the Company shall have the right to postpone the Closing Date or such Option Closing Date, as the case may be, for a period of not more than seven days in order to effect any necessary changes and arrangements (including any necessary amendments or supplements to the Registration Statement or Prospectus or any other documents), and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in the opinion of the Company and the Underwriters and their counsel may thereby be made necessary.

The term “Underwriter” as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with like effect as if such substituted Underwriter had originally been named in Schedule 1.

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of such Securities which remains unpurchased exceeds 10% of the aggregate number of all the Securities to be purchased at such date, then this Agreement, or, with respect to any Option Closing Date which occurs after the Closing Date, the obligations of the Underwriters to purchase and of the Company, as the case may be, to sell the Option Securities to be purchased and sold on such date, shall terminate, without liability on the part of any non-defaulting Underwriter to the Company, and without liability on the part of the Company, except as provided in Sections 4(b), 5, 6 and 7. The provisions of this Section 8 shall not in any way affect the liability of any defaulting Underwriter to the Company or the nondefaulting Underwriters arising out of such default. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 8 with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

9. Additional Covenants.

(a) Board Composition and Board Designations. The Company shall ensure that: (i) the qualifications of the persons serving as members of the Board of Directors and the overall composition of the Board comply with the Sarbanes-Oxley Act, with the Exchange Act, the Israeli Companies Law, and with the listing rules of the Exchange or any other national securities exchange, as the case may be, in the event the Company seeks to have its Ordinary Shares listed on another exchange or quoted on an automated quotation system, and (ii) if applicable, at least one member of the Audit Committee of the Board of Directors qualifies as an “audit committee financial expert,” as such term is defined under Regulation S-K and the listing rules of the Exchange.

(b) Prohibition on Press Releases and Public Announcements. The Company shall not issue press releases or engage in any other publicity, without the Representative’s prior written consent, for a period ending at 5:00 p.m., Eastern time, on the first (1st) business day following the forty-fifth (45th) day after the Closing Date, other than normal and customary releases issued in the ordinary course of the Company’s business or if in the judgment of the Company and its counsel, and after notification to the Representative, such press release or communication is required by law.

10. Additional Rights.

(a) Right of First Refusal. For a period of nine (9) months after the Closing Date, the Representative shall have a right of first refusal (the “Right of First Refusal”) to act as lead book-runner, lead manager, lead placement agent or lead agent or in any other similar capacity, on the Representative’s customary terms and conditions, in the event the Company retains or otherwise uses (or seeks to retain or use) the services of an investment bank or placement agent to (i) finance or refinance any indebtedness or (ii) pursue a registered offering (in addition to the Offering) or a private placement of equity or debt securities (each, a “ Subject Transaction”). The Company shall notify the Representative of its intention to pursue a Subject Transaction, including the terms of such Subject Transaction, by providing written notice thereof (a “ Subject Transaction Notice ”) by e-mail, registered mail or overnight courier service addressed to the Representative delivered in accordance with Section 11 of this Agreement. If the Representative fails to exercise its Right of First Refusal with respect to any Subject Transaction within five (5) business days after the mailing of such written notice, then the Representative shall have no further claim or right with respect to the Subject Transaction. The Representative may elect, in its sole and absolute discretion, not to exercise its Right of First Refusal with respect to any Subject Transaction; provided that any such election by the Representative shall not adversely affect the Representative’s Right of First Refusal with respect to any other Subject Transaction during the term of this right. The terms and conditions of any such engagements shall be set forth in separate agreements and may be subject to, among other things, satisfactory completion of due diligence by the Representative, market conditions, the absence of a Material Adverse Change, approval of the Representative’s internal committee and any other conditions that the Representative may deem appropriate for transactions of such nature.

(b) Tail Financing. The Representative shall be entitled to the compensation set forth herein with respect to any public or private offering or other financing or capital-raising transaction of any kind (“Tail Financing”) to the extent that such Tail Financing is provided to the Company by any investors in this offering or whom the Representative had introduced to the Company in connection with the Offering and whom are set forth on Schedule 4 hereto, if such Tail Financing is consummated at any time within the 9-month period following the Closing Date.

11. Miscellaneous. The respective agreements, representations, warranties, indemnities and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or the Company or any of their respective officers, directors or controlling persons referred to in Sections 5 and 6 hereof, and shall survive delivery of and payment for the Securities. In addition, the provisions of Sections 4(b), 5, 6 and 7 shall survive the termination or cancellation of this Agreement.

This Agreement has been and is made for the benefit of the Underwriters, the Company and their respective successors and assigns, and, to the extent expressed herein, for the benefit of persons controlling any of the Underwriters, or the Company, and directors and officers of the Company, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term “successors and assigns” shall not include any purchaser of Securities from any Underwriter merely because of such purchase.

This Agreement (together with the other agreements and documents being delivered pursuant to or in connection with this Agreement) constitutes the entire agreement of the parties hereto with respect to the subject matter hereof and thereof, and supersedes all prior agreements and understandings of the parties, oral and written, with respect to the subject matter hereof, except for that amended and restated engagement letter, dated as of February 17, 2017, by and between the Company and the Representative.

All notices, consents and other communications hereunder shall be in writing and mailed or delivered or by telephone if subsequently confirmed in writing, (a) if to the Representative, to H.C. Wainwright & Co., LLC, 430 Park Avenue, New York, New York 10022 Attention: Head of Investment Banking (notices@hcwco.com), with copies to (i) Haynes and Boone, LLP, 30 Rockefeller Plaza, 26th Floor, New York, New York 10112, Attention: Rick A.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

By the execution and delivery of this Agreement, the Company hereby irrevocably designates and appoints Zysman, Aharoni, Gayer and Sullivan & Worcester LLP, 1633 Broadway, New York, NY 10019 as its authorized agent upon whom process may be served in any suit, proceeding or other action against it instituted by any Underwriter or by any person controlling an Underwriter as to which such Underwriter or any such controlling person is a party and based upon this Agreement, or in any other action against the Company in the New York Supreme Court, County of New York and the United States District Court for the Southern District of New York, arising out of the offering made by the Prospectus or any purchase or sale of Securities in connection therewith. The Company expressly accepts jurisdiction of any such court in respect of any such suit, proceeding or other action and, without limiting other methods of obtaining jurisdiction, expressly submits to nonexclusive personal jurisdiction of any such court in respect of any such suit, proceeding or other action. Such designation and appointment shall be irrevocable, unless and until a successor authorized agent in the County and State of New York reasonably acceptable to the Representative shall have been appointed by the Company, such successor shall have accepted such appointment and written notice thereof shall have been given to the Underwriters. The Company further agrees that service of process upon its authorized agent or successor shall be deemed in every respect personal service of process upon the Company in any such suit, proceeding or other action. In the event that service of any process or notice of motion or other application to any such court in connection with any such motion in connection with any such action or proceeding cannot be made in the manner described above, such service may be made in the manner set forth in conformance with the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents on Civil and Commercial Matters or any successor convention or treaty. The Company hereby irrevocably waives any objection that it may have or hereafter have to the laying of venue of any such action or proceeding arising out of or based on the Securities, or this Agreement or otherwise relating to the offering, issuance and sale of the Securities in any Federal or state court sitting in the County of New York and hereby further irrevocably waives any claim that any such action or proceeding in any such court has been brought in an inconvenient forum. The Company agrees that any final judgment after exhaustion of all appeals or the expiration of time to appeal in any such action or proceeding arising out of the sale of the Securities or this Agreement rendered by any such Federal court or state court shall be conclusive and may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by law. Nothing contained in this Agreement shall affect or limit the right of the Underwriters or any person controlling an Underwriter to serve any process or notice of motion or other application in any other manner permitted by law or limit or affect the right of the Underwriters or any person controlling an Underwriter to bring any action or proceeding against the Company or any of its properties in the courts of any other jurisdiction. The Company further agrees to take any and all action, including the execution and filing of all such instruments and documents, as may be necessary to continue such designations and appointments or such substitute designations and appointments in full force and effect. The Company hereby agrees with the Underwriters to the nonexclusive jurisdiction of the New York Supreme Court, County of New York or the United States District Court for the Southern District of New York in connection with any action or proceeding arising from the sale of the Securities or this Agreement brought by the Company, the Underwriters or any person controlling an Underwriter. The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

The Company agrees that in any suit (whether in a court in the United States, Israel or elsewhere) seeking enforcement of this Agreement or provisions of this Agreement (i) if the plaintiffs therein seek a judgment in either United States dollars or Israeli currency, subject to Israeli foreign currency control regulations, the Company will not interpose any defense or objection to or otherwise oppose judgment, if any, being awarded in such currencies except to the extent that such a judgment would violate the laws of the State of Israel, and (ii) if the plaintiffs therein seek to have any judgment (or any aspect thereof) awarded in New Israeli Shekels linked, for the period from entry of such judgment until actual payment thereof in full has been made, to either or both of the consumer price index of Israel or changes in the New Israeli Shekel-United States dollar exchange rate, the Company will not interpose any defense or objection to or otherwise oppose inclusion of such linkage in any such judgment except to the extent that such a judgment would violate the laws of the State of Israel. The Company agrees that it will not initiate or seek to initiate any action, suit or proceeding, in Israel or in any other jurisdiction other than in the United States, seeking damages in respect of or for the purpose of obtaining any injunction or declaratory judgment against the enforcement of, or a declaratory judgment concerning any alleged breach by the Company or other claim by the Underwriters, or any person controlling an Underwriter in respect of this Agreement or any of the Underwriters’ rights under this Agreement, including without limitation any action, suit or proceeding challenging the enforceability of or seeking to invalidate in any respect the submission by the Company hereunder to the jurisdiction of the courts or the designation of the laws as the law applicable to this Agreement, in each case as set forth herein.

The Company agrees that if any payment of any sum due under this Agreement from the Company is made to or received by the Underwriters or any controlling person of any Underwriter in a currency other than freely transferable United States dollars, whether by judicial judgment or otherwise, the obligations of the Company under this Agreement shall be discharged only to the extent of the net amount of freely transferable United States dollars that the Underwriters or such controlling persons, as the case may be, in accordance with normal bank procedures, are able to lawfully purchase with such amount of such other currency. To the extent that the Underwriters or such controlling persons are not able to purchase sufficient United States dollars with such amount of such other currency to discharge the obligations of the Company to the Underwriters or such controlling persons, the obligations of the Company shall not be discharged with respect to such difference, and any such undischarged amount will be due as a separate obligation and shall not be affected by payment of or judgment being obtained for any other sums due under or in respect of this Agreement.

This Agreement may executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original and all such counterparts shall together constitute one and the same instrument. Execution and delivery of a signed counterpart of this Agreement by facsimile or e-mail/.pdf transmission shall constitute valid and sufficient execution and delivery thereof.
