EKSO BIONICS HOLDINGS, INC.

THIS STOCK OPTION AGREEMENT (this “Agreement”) is entered into as of the ___ day of ______________, 20___ (the “Date of Grant”)

BETWEEN:

EKSO BIONICS HOLDINGS, INC., a company incorporated pursuant to the laws of the State of Nevada (the “Company”),

AND:

[_______________], of ________________________________ (the “Optionee”).

WHEREAS:

A.           The Board of Directors of the Company (the “Board”) has approved and adopted the Ekso Bionics Holdings, Inc. 2014 Equity Incentive Plan (the “2014 Plan”), pursuant to which the Board is authorized to grant to employees and other selected service providers and persons, including members of the Board, stock options to purchase common shares of the Company (the “Common Stock”);

B.           The 2014 Plan provides for the granting of stock options that either (i) are intended to qualify as “Incentive Stock Options” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or (ii) do not satisfy the requirements for qualification under Section 422 of the Code (“Nonstatutory Stock Options”); and

C.           The Board has authorized the grant to Optionee of options to purchase a total of [_______________] ([____]) shares of Common Stock (the “Options”), which Options are intended to be (select one):

NOW THEREFORE, the Company agrees to offer to the Optionee the option to purchase, upon the terms and conditions set forth herein and in the Plan, [__________] ([____]) shares of Common Stock. Capitalized terms not otherwise defined herein shall have the meanings ascribed thereto in the 2014 Plan.

1.           Exercise Price. The exercise price of the options shall be US$[_____] per share.

2.           Limitation on the Number of Shares. If the Options granted hereby are Incentive Stock Options, the number of shares which may be acquired upon exercise thereof is subject to the limitations set forth in Section 6(a) of the 2014 Plan.

3.           Vesting Schedule. The Options shall vest in accordance with Exhibit A attached hereto.

4.           Options not Transferable. Subject to Section 13 of the 2014 Plan, the Options may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner (whether by operation of law or otherwise) other than by will or by the laws of descent or distribution or, in the case of a Nonstatutory Stock Option, pursuant to a qualified domestic relations order, and shall not be subject to execution, attachment or similar process; provided, however, that if the Options represent a Nonstatutory Stock Option, such Option is transferable without payment of consideration to immediate family members of the Optionee or to trusts or partnerships established exclusively for the benefit of the Optionee and Optionee’s immediate family members. Upon any attempt to transfer, pledge, hypothecate or otherwise dispose of any Option or of any right or privilege conferred by the 2014 Plan contrary to the provisions thereof, or upon the sale, levy or attachment or similar process upon the rights and privileges conferred by the 2014 Plan, such Option shall thereupon terminate and become null and void.

5.           Investment Intent. By accepting the Options, the Optionee represents and agrees that none of the shares of Common Stock purchased upon exercise of the Options will be distributed in violation of applicable federal and state laws and regulations. In addition, the Company may require, as a condition of exercising the Options, that the Optionee execute an undertaking, in such a form as the Company shall reasonably specify, that the Stock is being purchased only for investment and without any then-present intention to sell or distribute such shares.

6.           Termination of Employment and Options. Vested Options shall terminate, to the extent not previously exercised, upon the occurrence of the first of the following events:

Each unvested Option granted pursuant hereto shall terminate immediately upon termination of the Optionee’s employment or contractual relationship with the Company for any reason whatsoever, including Disability unless vesting is accelerated in accordance with the 2014 Plan.

7.           Stock. In the case of any stock split, stock dividend or like change in the nature of shares of Stock covered by this Agreement, the number of shares and exercise price shall be proportionately adjusted as set forth in Section 14(a) of the 2014 Plan.

8.           Exercise of Option. Options shall be exercisable, in full or in part, at any time after vesting, until termination; provided, however, that any Optionee who is subject to the reporting and liability provisions of Section 16 of the Securities Exchange Act of 1934, as amended, with respect to the Common Stock shall be precluded from selling or transferring any Common Stock or other security underlying an Option during the six (6) months immediately following the grant of that Option. If less than all of the shares included in the vested portion of any Option are purchased, the remainder may be purchased at any subsequent time prior to the expiration of the Option term. Only whole shares may be issued pursuant to an Option, and to the extent that an Option covers less than one (1) share, it is unexercisable.

Each exercise of the Option shall be by means of delivery of a notice of election to exercise (which may be in the form attached hereto as Exhibit B) to the Chief Financial Officer of the Company at its principal executive office, specifying the number of shares of Common Stock to be purchased and accompanied by payment in cash by certified check or cashier’s check in the amount of the full exercise price for the Common Stock to be purchased. In addition to payment in cash by certified check or cashier’s check, an Optionee or transferee of an Option may pay for all or any portion of the aggregate exercise price by complying with one or more of the following alternatives:

It is a condition precedent to the issuance of shares of Common Stock that the Optionee execute and/or deliver to the Company all documents and withholding taxes required in accordance with Section 15 of the 2014 Plan.

9.           Holding period for Incentive Stock Options. In order to obtain the tax treatment provided for Incentive Stock Options by Section 422 of the Code, the shares of Common Stock received upon exercising any Incentive Stock Options received pursuant to this Agreement must be sold, if at all, after a date which is later of two (2) years from the date of this Agreement is entered into or one (1) year from the date upon which the Options are exercised. The Optionee agrees to report sales of shares prior to the above determined date to the Company within one (1) business day after such sale is concluded. The Optionee also agrees to pay to the Company, within five (5) business days after such sale is concluded, the amount necessary for the Company to satisfy its withholding requirement required by the Code. Nothing in this Section 9 is intended as a representation that Common Stock may be sold without registration under state and federal securities laws or an exemption therefrom or that such registration or exemption will be available at any specified time.

10.         Resale restrictions may apply. Any resale of the shares of Common Stock received upon exercising any Options will be subject to resale restrictions contained in the securities legislation applicable to the Optionee. The Optionee acknowledges and agrees that the Optionee is solely responsible (and the Company is not in any way responsible) for compliance with applicable resale restrictions.

11.         Subject to 2014 Plan. The terms of the Options are subject to the provisions of the 2014 Plan, as the same may from time to time be amended, and any inconsistencies between this Agreement and the 2014 Plan, as the same may be from time to time amended, shall be governed by the provisions of the 2014 Plan, a copy of which has been delivered to the Optionee, and which is available for inspection at the principal offices of the Company.

12.         Professional Advice. The acceptance of the Options and the sale of Common Stock issued pursuant to the exercise of Options may have consequences under federal and state tax and securities laws which may vary depending upon the individual circumstances of the Optionee. Accordingly, the Optionee acknowledges that he or she has been advised to consult his or her personal legal and tax advisor in connection with this Agreement and his or her dealings with respect to Options. Without limiting other matters to be considered with the assistance of the Optionee’s professional advisors, the Optionee should consider: (a) whether upon the exercise of Options, the Optionee will file an election with the Internal Revenue Service pursuant to Section 83(b) of the Code and the implications of alternative minimum tax pursuant to the Code; (b) the merits and risks of an investment in the underlying shares of Common Stock; and (c) any resale restrictions that might apply under applicable securities laws.

13.         No Employment Commitment. The grant of the Options shall in no way constitute any form of agreement or understanding binding on the Company or any Related Company, express or implied, that the Company or any Related Company will employ or contract with the Optionee, for any length of time, nor shall it interfere in any way with the Company’s or, where applicable, a Related Company’s right to terminate Optionee’s employment at any time, which right is hereby reserved.

14.         Entire Agreement. This Agreement is the only agreement between the Optionee and the Company with respect to the Options, and this Agreement and the 2014 Plan supersede all prior and contemporaneous oral and written statements and representations and contain the entire agreement between the parties with respect to the Options.

15.         Notices. Any notice required or permitted to be made or given hereunder shall be mailed or delivered personally to the addresses set forth below, or as changed from time to time by written notice to the other:
