Ladies and Gentlemen:

PLURISTEM THERAPEUTICS INC., a Nevada corporation (the “Company”), proposes to issue and sell to Ladenburg ▇▇▇▇▇▇▇▇ & Co. Inc. (the “Representative”) and the other underwriters listed on Schedule I hereto (collectively, with the Representative, the “Underwriters”), pursuant to and in accordance with the terms and conditions of this underwriting agreement (the “Agreement”) in a public offering (the “Offering”), an aggregate of 27,142,858 shares (the “Shares”) of its common stock, par value $0.00001 per share (the “Common Stock”), and warrants (each whole warrant, a “Warrant”) to purchase up to an aggregate of 27,142,858 shares of Common Stock. The Shares to be sold by the Company are called the “Firm Shares.” The Firm Shares and the Warrants will be sold as units (the “Units”), with each Unit consisting of one Share and a Warrant to purchase one Share. In addition, the Company has granted to the Underwriters an option to purchase up to an additional 1,428,571 Shares as provided in Section 3 (the “Option Shares”) and/or Warrants to purchase up to an additional 1,428,571 Shares (the “Option Warrants” and, collectively with the Option Shares, the “Option Securities”). The Units, the Shares, the Warrants, the Option Securities and the Warrant Shares (as defined below) are collectively called the “Securities.” The Shares underlying the Warrants and Option Warrants are collectively called the “Warrant Shares.”

This is to confirm the agreement concerning the purchase of the Securities from the Company by the Underwriters.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a shelf registration statement on Form S-3, File No. 333-218916, including a base prospectus (the “Base Prospectus”) to be used in connection with the public offering and sale of the Securities. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), including all documents incorporated or deemed to be incorporated by reference therein and any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A or 430B under the Securities Act, is called the “Registration Statement.” Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act in connection with the offer and sale of the Securities is called the “Rule 462(b) Registration Statement,” and from and after the date and time of filing of any such Rule 462(b).

The term “Registration Statement” shall include the Rule 462(b) Registration Statement. The preliminary prospectus supplement dated April 3, 2019 describing the Securities and the offering thereof (the “Preliminary Prospectus Supplement”), together with the Base Prospectus, is called the “Preliminary Prospectus,” and the Preliminary Prospectus and any other prospectus supplement to the Base Prospectus in preliminary form that describes the Securities and the offering thereof and is used prior to the filing of the Prospectus (as defined below), together with the Base Prospectus, is called a “preliminary prospectus.” As used herein, the term “Prospectus” shall mean the final prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof, together with the Base Prospectus, in the form first used by the Underwriters to confirm sales of the Securities or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act. References herein to the Preliminary Prospectus, any preliminary prospectus and the Prospectus shall refer to both the prospectus supplement and the Base Prospectus components of such prospectus. As used herein, “Applicable Time” is 8:40 a.m. (New York City time) on the date of this Agreement. As used herein, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, and “Time of Sale Prospectus” means the Preliminary Prospectus, as amended or supplemented immediately prior to the Applicable Time, together with the free writing prospectuses, if any, identified on Schedule II hereto. As used herein, “Road Show” means a “road show” (as defined in Rule 433 under the Securities Act) relating to the offering of the Securities contemplated hereby that is a “written communication” (as defined in Rule 405 under the Securities Act).

All references in this Agreement to the Registration Statement, the Preliminary Prospectus, any preliminary prospectus, the Base Prospectus and the Prospectus shall include the documents incorporated or deemed to be incorporated by reference therein. All references in this Agreement to financial statements and schedules and other information which are “contained,” “included” or “stated” in, or “part of” the Registration Statement, the Rule 462(b) Registration Statement, the Preliminary Prospectus, any preliminary prospectus, the Base Prospectus, the Time of Sale Prospectus or the Prospectus, and all other references of like import, shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Rule 462(b) Registration Statement, the Preliminary Prospectus, any preliminary prospectus, the Base Prospectus, the Time of Sale Prospectus or the Prospectus, as the case may be. All references in this Agreement to amendments or supplements to the Registration Statement, the Preliminary Prospectus, any preliminary prospectus, the Base Prospectus, the Time of Sale Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”) that is or is deemed to be

incorporated by reference in the Registration Statement, the Preliminary Prospectus, any preliminary prospectus, the Base Prospectus, or the Prospectus, as the case may be. All references in this Agreement to the Registration Statement, the Preliminary Prospectus, any preliminary prospectus, the Base Prospectus or the Prospectus, any amendments or supplements to any of the foregoing, or any free writing prospectus, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

Concurrently with the offer and sale of the Securities, the Company is offering shares of Common Stock directly to certain investors pursuant to the Registration Statement and a separate prospectus supplement to the Base Prospectus that describes the offering thereof (the “Concurrent Registered Direct Offering”) as disclosed in the Time of Sale Prospectus and the Prospectus.

1. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the Underwriters that:

(a) Compliance with Registration Requirements. The Registration Statement has become effective under the Securities Act. The Company has complied, to the Commission’s satisfaction, with all requests of the Commission for additional or supplemental information, if any. No stop order suspending the effectiveness of the Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, are contemplated or threatened by the Commission. At the time the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2018 (the “Annual Report”) was filed with the Commission, or, if later, at the time the Registration Statement was originally filed with the Commission, the Company met the then-applicable requirements for use of Form S-3 under the Securities Act. The Company meets the requirements for use of Form S-3 under the Securities Act and it meets the transaction requirements as set forth in General Instruction I.B.1 of Form S-3 and the requirements specified in the Financial Industry Regulatory Authority, Inc. (“FINRA”) Conduct Rule 5110(B)(7)(C)(i). The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Time of Sale Prospectus and the Prospectus, at the time they were or hereafter are filed with the Commission, or became effective under the Exchange Act, as the case may be, complied and will comply in all material respects with the requirements of the Exchange Act.

(b) Disclosure. Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities Act and, if filed by electronic transmission pursuant to ▇▇▇▇▇, was identical (except as may be permitted by Regulation S-T under the Securities Act) to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Securities. Each of the Registration Statement and any post-effective amendment thereto, at the time it became or becomes effective and at all subsequent times, complied and will comply in all material respects with the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, the Time of Sale Prospectus did not, and at the time of each sale of the Securities and at the First Closing Date (as defined in Section 4) and at each applicable Option Closing Date (as defined in Section 4), the Time of Sale Prospectus, as then amended or supplemented by the Company, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus, as of its date and (as then amended or supplemented) at all subsequent times, did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the three immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus or the Time of Sale Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with written information relating to any Underwriter furnished to the Company in writing by the Representative expressly for use therein, it being understood and agreed that the only such information consists of the information described in Section 12 below. There are no contracts or other documents required to be described in the Time of Sale Prospectus or the Prospectus or to be filed as an exhibit to the Registration Statement which have not been described or filed as required.

(c) Free Writing Prospectuses; Road Show. As of the determination date referenced in Rule 164(h) under the Securities Act, the Company was not, is not or will not be (as applicable) an “ineligible issuer” in connection with the offering of the Securities pursuant to Rules 164, 405 and 433 under the Securities Act. Each free writing prospectus, if any, that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act, including timely filing with the Commission or retention where required and legending, and each such free writing prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Prospectus or any preliminary prospectus and not superseded or modified. Except for the free writing prospectuses, if any, identified on Schedule II, and electronic road shows, if any, furnished to the Representative before first use, the Company has not prepared, used or referred to, and will not, without the Representative's prior written consent, prepare, use or refer to, any free writing prospectus in connection with the Securities or in connection with the Concurrent Registered Direct Offering. Each Road Show, when considered together with the Time of Sale Prospectus, does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Offering Materials Furnished to Underwriters. The Company has delivered to the Representative two complete copies of the Registration Statement and each amendment thereto (including, in each case, exhibits) and each consent and certificate of experts filed as a part thereof, and additional copies of the Registration Statement and each amendment thereto (without exhibits) and each preliminary prospectus and any free writing prospectus reviewed and consented to by the Representative, in such quantities and at such places as the Representative has reasonably requested for each of the Underwriters. Upon request of the Representative, the Company will provide to the Underwriters two complete, manually signed copies of the Registration Statement and each amendment thereto.

(e) Distribution of Offering Material by the Company. Prior to the later of (i) the expiration or termination of the option granted to the several Underwriters in Section 3 and (ii) the completion of the Underwriters’ distribution of the Securities, the Company has not distributed and will not distribute any offering material in connection with the offering and sale of the Securities other than the Registration Statement, the Time of Sale Prospectus, the Prospectus (each as amended or supplemented), or any free writing prospectus reviewed and consented to by the Representative. The Company has not distributed and will not distribute any offering material in connection with the offering and sale of the shares of Common Stock in the Concurrent Registered Direct Offering other than a form of subscription agreement, the Registration Statement and the prospectus supplement to the Base Prospectus that describes the offering thereof.

The Securities have been duly authorized for issuance and sale pursuant to this Agreement and, when issued and delivered by the Company against payment therefor pursuant to this Agreement or the terms of the Warrants, as the case may be, will be validly issued, fully paid and nonassessable, and the issuance and sale of the Securities is not subject to any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase the Securities. Upon the sale and delivery to the Underwriters of the Securities, and payment therefor, the Underwriters will acquire good, marketable and valid title to such Securities, free and clear of all pledges, liens, security interests, charges, claims or encumbrances.

There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, except for such rights as have been duly waived.

(i) No Material Adverse Effect. Except as otherwise disclosed in the Registration Statement, the Time of Sale Prospectus and the Prospectus, subsequent to the respective dates as of which information is given in the Registration Statement, the Time of Sale Prospectus and the Prospectus: (i) there has been no material adverse change, or any development that could be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business, properties, operations or prospects, whether or not arising from transactions in the ordinary course of business, of the Company and its subsidiaries, considered as one entity (any such change being referred to herein as a “Material Adverse Effect”); (ii) the Company and its subsidiaries, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the ordinary course of business nor entered into any material transaction or agreement not in the ordinary course of business; and (iii) there has been no dividend or distribution of any kind declared, paid or made by the Company or, except for dividends paid to the Company or other subsidiaries, by any of the Company’s subsidiaries on any class of capital stock, or any repurchase or redemption by the Company or any of its subsidiaries of any class of capital stock.

Such financial statements have been prepared in conformity with generally accepted accounting principles as applied in the United States applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement fairly presents, in all material respects, the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto. No other financial statements or supporting schedules are required to be included in the Registration Statement, the Time of Sale Prospectus or the Prospectus. The financial data set forth or incorporated by reference in each of the Registration Statement, the Time of Sale Prospectus and the Prospectus under the caption “Capitalization” fairly present the information set forth therein on a basis consistent with that of the financial statements contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus. All disclosures contained in the Registration Statement, any preliminary prospectus, the Prospectus and any free writing prospectus that constitute non-GAAP financial measures (as defined by the rules and regulations under the Securities Act and the Exchange Act) comply with Regulation G under the Exchange Act and Item 10 of Regulation S-K under the Securities Act, as applicable. To the Company’s knowledge, no person who has been suspended or barred from being associated with a registered public accounting firm, or who has failed to comply with any sanction pursuant to Rule 5300 promulgated by the PCAOB, has participated in or otherwise aided the preparation of, or audited, the financial statements, supporting schedules or other financial data filed with the Commission as a part of the Registration Statement, the Time of Sale Prospectus and the Prospectus.

(m) Disclosure Controls and Procedures; Deficiencies in or Changes to Internal Control Over Financial Reporting. The Company has established and maintains disclosure controls and procedures (as defined in Rules 13a-15 and 15d-15 under the Exchange Act), which (i) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated by management of the Company for effectiveness as of the end of the Company’s most recent fiscal quarter; and (iii) are effective in all material respects to perform the functions for which they were established. Since the end of the Company’s most recent audited fiscal year, to the Company’s knowledge, there have been no significant deficiencies or material weakness in the Company’s internal control over financial reporting (whether or not remediated) and no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company is not aware of any change in its internal control over financial reporting that has occurred during its most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

The descriptions of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth in the Registration Statement, the Time of Sale Prospectus and the Prospectus accurately and fairly presents, in all material respects, the information required to be shown with respect to such plans, arrangements, options and rights. The Company has reserved and kept available for the exercise of the Warrants and the Option Warrants such number of authorized but unissued Shares as are sufficient to permit the exercise in full of the Warrants and the Option Warrants.

(w) All Necessary Permits, etc. The Company and its subsidiaries possess such valid and current certificates, authorizations or permits required by state, federal or foreign regulatory agencies or bodies to conduct their respective businesses as currently conducted and as described in the Registration Statement, the Time of Sale Prospectus or the Prospectus (“Permits”), except where the failure to possess such valid and current certificates, authorizations or permits could not be expected, individually or in the aggregate, to have a Material Adverse Effect. Neither the Company nor any of its subsidiaries is in violation of, or in default under, any of the Permits or has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit.

(x) Title to Properties.

The real property, improvements, equipment and personal property held under lease by the Company or any of its subsidiaries are held under valid and enforceable leases, with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary.

(y) Tax Law Compliance.

No transaction, stamp or other issuance taxes or duties, and assuming that the Underwriters are not otherwise subject to taxation in Israel due to Israeli tax residence or the existence of a permanent establishment in Israel, no capital gain, income, transfer, withholding or other tax or duty is payable in the State of Israel by or on behalf of the Underwriters to any taxing authority thereof or therein in connection with (i) the issuance, sale and delivery of the Securities by the Company; (ii) the purchase from the Company, and the initial sale and delivery by the Underwriters of the Securities to purchasers thereof; (iii) the holding or transfer of the Securities; or (iv) the execution and delivery of this Agreement or any other document to be furnished hereunder.

The Company has no reason to believe that it or any of its subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that could not reasonably be expected to have a Material Adverse Effect. Neither the Company nor any of its subsidiaries has been denied any insurance coverage which it has sought or for which it has applied.

(aa) Compliance with Environmental Laws. Except as could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect: (i) neither the Company nor any of its subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”); (ii) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements; (iii) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its subsidiaries; and (iv) to the Company’s knowledge, there are no events or circumstances that could reasonably be expected to form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, foreign or domestic, against or affecting the Company or any of its subsidiaries relating to Hazardous Materials or any Environmental Laws.

(bb) Compliance with the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. The Company and its subsidiaries are in compliance in all material respects with all provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and all rules and regulations promulgated thereunder (collectively, the “▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act”) that are then in effect and with which each such entity is required to comply and with all corporate governance requirements under applicable Nasdaq regulations, and have no reason to believe that they will not be able to comply with any of such provisions. There is and has been no failure on the part of the Company or any subsidiary or any of their directors or officers, in their capacities as such, to comply with any applicable provision of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, including, without limitation, Section 402 related to loans and Sections 302 and 906 related to certifications.

(cc) Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business, the Company conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). No facts or circumstances have come to the Company’s attention that could result in costs or liabilities that could be expected, individually or in the aggregate, to have a Material Adverse Effect.

(dd) ERISA Compliance. The Company and its subsidiaries and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company or any of its subsidiaries, any member of any group of organizations described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each employee benefit plan established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification.

(ff) No Price Stabilization or Manipulation; Compliance with Regulation M. Neither the Company nor any of its subsidiaries has taken, directly or indirectly, any action designed to or that could be reasonably expected to cause or result in stabilization or manipulation of the price of the Shares or of any “reference security” (as defined in Rule 100 of Regulation M under the Exchange Act (“Regulation M”)) with respect to the Shares, whether to facilitate the sale or resale of the Securities or otherwise, and has taken no action which would directly or indirectly violate Regulation M.

(a) During such period beginning on the Applicable Time and ending on the later of the Closing Date or such date, as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales as contemplated by this Agreement by any Underwriter or any dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement (including any registration statement filed under Rule 462(b) under the Securities Act), the Time of Sale Prospectus or the Prospectus, the Company shall furnish to the Representative for review a copy of each such proposed amendment or supplement, and the Company shall not file any such proposed amendment or supplement to which the Representative reasonably objects.

(b) After the date of this Agreement and for period of two years thereafter, the Company shall promptly advise the Representative in writing (i) when the Registration Statement, if not effective at the date and time that this Agreement is executed and delivered by the parties hereto, shall have become effective, (ii) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (iii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any Preliminary Prospectus or the Prospectus, (iv) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or of any order or notice preventing or suspending the use of the Registration Statement, any Preliminary Prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Common Stock from any securities exchange upon which it is listed for trading or included or designated (or approved for inclusion or designation) for quotation, or of the threatening or initiation of any proceedings for any of such purposes. The Company shall use its best efforts to prevent the issuance of any such stop order or prevention or suspension of such use. If the Commission shall enter any such stop order or order or notice of prevention or suspension at any time, the Company will use its best efforts to obtain the lifting of such order at the earliest possible moment, or will file a new registration statement and use its best efforts to have such new registration statement declared effective as soon as practicable. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b) and 434, as applicable, under the Securities Act, including with respect to the timely filing of documents thereunder, and will use its reasonable efforts to confirm that any filings made by the Company under such Rule 424(b) were received in a timely manner by the Commission.

(c) (i) If the Preliminary Prospectus included in the Time of Sale Prospectus is being used to solicit offers to buy the Securities and any event or development shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in light of the circumstances under which they were made or then prevailing, as the case may be, not misleading (in which case the Company agrees to notify the Representative promptly of any such event or condition), or if in the reasonable opinion of the Representative it is otherwise necessary to amend or supplement the Time of Sale Prospectus to comply with law, the Company agrees to promptly prepare, file with the Commission and furnish to the Underwriters and to dealers, at its own expense, amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not be, in the light of the circumstances under which they were made or then prevailing, as the case may be, misleading or so that the Time of Sale Prospectus, as amended or supplemented, will comply with law; (ii) if, during the Prospectus Delivery Period, any event or development shall occur or condition exist as a result of which it is necessary to amend or supplement the Registration Statement or the Prospectus in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading (in which case the Company agrees to notify the Representative promptly of any such event or condition), or if in the reasonable opinion of the Representative it is otherwise necessary to amend or supplement the Registration Statement or the Prospectus to comply with law, including in connection with the delivery of the Prospectus, the Company agrees to promptly prepare, file with the Commission (and use its best efforts to have any amendment to the Registration Statement or any new registration statement to be declared effective) and furnish to the Underwriters and to dealers, amendments or supplements to the Registration Statement or the Prospectus, or any new registration statement so that the statements in the Registration Statement or the Prospectus as so amended or supplemented will not be, in the light of the circumstances under which they were made or then prevailing, as the case may be, misleading or so that the Registration Statement or the Prospectus, as amended or supplemented, will comply with law.

(d) The Company agrees that, unless it obtains the prior written consent of the Representative, it will not make any offer relating to the Common Stock that would constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act; provided that the prior written consent of the Representative hereto shall be deemed to have been given in respect of any free writing prospectus included in Schedule II hereto. Any such free writing prospectus consented to by the Representative is hereinafter referred to as a “Permitted Free Writing Prospectus”. The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as a free writing prospectus, and (ii) has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(e) The Company shall furnish to the Underwriters, from time to time and without charge, copies of the Registration Statement of which three shall be signed and shall include exhibits and all amendments and supplements to any of such Registration Statement, in each case as soon as available and in such quantities as the Underwriters may from time to time reasonably request.

7. Indemnification and Contribution.

(a) The Company agrees to indemnify, defend and hold harmless each of the Underwriters and any person who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the respective directors, officers, employees and agents of each Underwriter from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, such Underwriter or any such director, officer, employee, agent or controlling person may incur under the Securities Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (A) any breach of any representation, warranty or covenant of the Company contained herein, (B) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereof), the Time of Sale Prospectus or the Prospectus (the term Prospectus for the purpose of this Section being deemed to include the preliminary prospectus included in the Registration Statement at the time it became effective, the Prospectus and the Prospectus as amended or supplemented by the Company), (C) any application or other document, or any amendment or supplement thereto, executed by the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction (domestic or foreign) in order to qualify the Common Stock under the securities or blue sky laws thereof or filed with the Commission or any securities association or securities exchange (each an “Application”), (D) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, or (E) any omission or alleged omission from the Time of Sale Prospectus, Prospectus or any Application of a material fact necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading; except in the case of (B), (D) and (E) above only insofar as any such loss, expense, liability, damage or claim arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in and in conformity with information furnished in writing by the Underwriter to the Company expressly for use in such Registration Statement, Time of Sale Prospectus, Prospectus or Application; and to promptly reimburse the Underwriters, or any such director, officer, employee, agent or controlling person for any legal and other expense reasonably incurred by the Underwriter, or any such director, officer, employee, agent or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 7(a) shall be in addition to any liability which the Company may otherwise have.

(b) Each of the Underwriters agrees, severally and not jointly, to indemnify, defend and hold harmless the Company, the Company’s directors, the Company’s officers that signed the Registration Statement, and any person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which the Company or any such person may incur under the Securities Act, the Exchange Act or otherwise, insofar as such loss, expense, liability, damage or claim arises out of or is based upon (A) any breach of any representation, warranty or covenant of such Underwriter contained herein, (B) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereof), the Time of Sale Prospectus, the Prospectus, or any Application, (C) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, or (D) any omission or alleged omission from the Time of Sale Prospectus, Prospectus or any Application of a material fact necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading, but in each case only insofar as such untrue statement or alleged untrue statement or omission or alleged omission was made in such Registration Statement, Time of Sale Prospectus, Prospectus or Application in reliance upon and in conformity with information furnished in writing by the Underwriter to the Company expressly for use therein; and to promptly reimburse the Company, or any such director, officer, employee or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The indemnity agreement set forth in this Section 7(b) shall be in addition to any liabilities that the Underwriters may otherwise have.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the claim or the commencement of that action; the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party except to the extent such indemnifying party has been materially prejudiced otherwise than under such subsection. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party provided, however, that if the named parties in any such action (including impleaded parties) include any of the Underwriters or any director, officer, employee, agent or controlling person of any of the Underwriters as an indemnified party or parties as well as the Company, and such indemnified party or parties shall have reasonably concluded, based on advice of outside counsel, that there may be one or more legal defenses reasonably available to it or them which are different from or additional to those available to the Company, or that representation of the indemnified party or parties and the Company by the same counsel would be inappropriate due to actual or potential differing interests between them, the Company shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under such subsection for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation unless such indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence, in which case the indemnifying party shall be liable for all legal fees and expenses of such separate counsel.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) and (b) of this Section 7 in respect of any losses, expenses, liabilities, damages or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, expenses, liabilities, damages or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the applicable Underwriter, on the other hand, from the offering of the Securities or (ii) if (but only if) the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the applicable Underwriter, on the other hand, in connection with the statements or omissions which resulted in such losses, expenses, liabilities, damages or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company and the applicable Underwriter shall be deemed to be in the same proportion as the total proceeds from the Offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bear to the underwriting discounts and commissions received by such Underwriter. The relative fault of the Company and of the applicable Underwriter shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the applicable Underwriter, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any claim or action.

(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in subsection (d)(i) and, if applicable (ii), above. Notwithstanding the provisions of this Section 7, no Underwriter 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.

8. Effective Date and Termination.

(a) [RESERVED]

(b) Until the First Closing Date, this Agreement may be terminated by the Representative by giving notice as hereinafter provided to the Company if: (i) the Company shall have failed, refused or been unable, at or prior to the First Closing Date, to perform any agreement on its part to be performed hereunder, unless the failure to perform any agreement is due to the default or omission by an Underwriter; (ii) any other condition of the obligations of the Underwriters hereunder is not fulfilled; (iii) trading in securities generally on the New York Stock Exchange or Nasdaq shall have been suspended or minimum or maximum prices shall have been established on either of such exchanges by the Commission or by such exchange or other regulatory body or governmental authority having jurisdiction; (iv) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by Nasdaq or other stock exchange or regulatory body or governmental authority having jurisdiction, including the Israel Securities Authority and the TASE; (v) a general banking moratorium shall have been declared by Federal or state authorities; (vi) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred; (vii) there shall have been any material adverse change in general economic, political or financial conditions or if the effect of international conditions on the financial markets in the United States shall be such as, in the Representative’s judgment, makes it inadvisable to proceed with the delivery of the Securities; or (viii) any attack on, outbreak or escalation of hostilities, declaration of war or act of terrorism involving the United States or any other national or international calamity or emergency if, in the Representative’s judgment, the effect of any such attack, outbreak, escalation, declaration, act, calamity or emergency makes it impractical or inadvisable to proceed with the completion of the public offering or the delivery of the Securities. Any termination of this Agreement pursuant to this Section 8 shall be without liability on the part of the Company or the Underwriters, except as otherwise provided in Sections 5(o) or 7 hereof.

Any notice referred to above may be given at the address specified in Section 11 hereof in writing or by telegraph or telephone, and if by telegraph or telephone, shall be immediately confirmed in writing.

9. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail on any Closing Date, as applicable, to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i)

if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii)

if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Option Closing Date, the obligation of the Underwriters to purchase, and the Company to sell, the Option Shares to be purchased and sold on such Option Closing Date shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of an Option Closing Date, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Shares, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone the Closing Date, as applicable, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, Time of Sale Prospectus or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9.

10. Survival of Indemnities, Contribution, Warranties and Representations. All representations, warranties, and agreements of the Company and the Underwriters herein or in certificates delivered pursuant hereto, and the agreements of the Underwriters and the Company contained in Section 7 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriters or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, and shall survive delivery of, and payment for, the Securities to and by the Underwriters hereunder.

As Representative of the Several Underwriters

Re: Public Offering by Pluristem Therapeutics Inc.

Ladies and Gentlemen:

The undersigned, an officer, director or holder of common stock, par value $0.00001 per share (“Common Stock”), or rights to acquire Common Stock, of Pluristem Therapeutics Inc. (the “Company”) understands that you, as Representative of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company, providing for the public offering (the “Offering”) by the several Underwriters named in Schedule I to the Underwriting Agreement (the “Underwriters”), of securities of the Company (the “Securities”) pursuant to a registration statement on Form S-3 (as amended, the “Registration Statement”) filed with the Securities and Exchange Commission (the “SEC”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to enter into the Underwriting Agreement and to proceed with the Offering of the Securities, and for other good and valuable consideration, receipt of which is hereby acknowledged, the undersigned hereby agrees for the benefit of the Company, you and the other Underwriters that, without the prior written consent of the Representative on behalf of the Underwriters, the undersigned will not, during the period commencing on the date hereof and ending ninety (90) days (the “Lock-Up Period”) after the date of the final prospectus supplement relating to the Offering (the “Prospectus”), directly or indirectly: (a) offer, pledge, assign, encumber, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock owned either of record or beneficially or may be deemed to be beneficially owned (as defined in the Securities Exchange Act of 1934, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Exchange Act”)) by the undersigned on the date hereof or hereafter acquired; or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise; or (c) make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock; or (d) publicly announce an intention to do any of the foregoing.

The foregoing paragraph shall not apply to (a) the registration of the offer and sale of Securities as contemplated by the Underwriting Agreement and the sale of the Securities to the Underwriters in the Offering and/or participation of the undersigned in the Offering, (b) bona fide gifts, provided the recipient thereof agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, (c) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement, (d) transfers of Common Stock or securities convertible into Common Stock on death by will or intestacy, (e) sales or transfers of Common Stock solely in connection with the “cashless” exercise of Company stock options outstanding on the date hereof for the purpose of exercising such stock options (provided that any remaining Common Stock received upon such exercise will be subject to the restrictions provided for in this Lock-Up Agreement) or (f) sales or transfers of Common Stock or securities convertible into Common Stock pursuant to a sales plan entered into prior to the date hereof pursuant to Rule 10b5-1 under the Exchange Act, a copy of which has been, or will be, provided to the Underwriters. In addition, the restrictions sets forth herein shall not prevent the undersigned from entering into a sales plan pursuant to Rule 10b5-1 under the Exchange Act after the date hereof, provided that (i) a copy of such plan is provided to the Underwriters promptly upon entering into the same and (ii) no sales or transfers may be made under such plan until the Lock-Up Period ends or this Lock-Up Agreement is terminated in accordance with its terms. For purposes of this paragraph, “immediate family” shall mean the undersigned and the spouse, any lineal descendent, father, mother, brother or sister of the undersigned.

In addition, the undersigned hereby waives any rights the undersigned may have to require registration of Common Stock in connection with the filing of a registration statement relating to the Offering.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that the undersigned shall be released from all obligations under this Lock-Up Agreement if (a) the Underwriting Agreement does not become effective by April 30, 2019 or, if after becoming effective, the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, or (b) the Company provides written notice to the Underwriters that the Company does not intend to proceed with the Offering.

The undersigned, whether or not participating in the Offering, understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Offering in reliance upon this Lock-Up Agreement.

This Lock-Up Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Very truly yours,
