Except as otherwise provided herein, if your employment by the Company is terminated by the Company with Cause, if you voluntarily terminate your employment with the Company, you shall not be entitled to any severance pay, severance benefits, or any compensation or benefits from the Company whatsoever, other than as required under applicable law.

That documentation must be provided to the Company within three business days of your date of hire, or our employment relationship with you may be terminated. You will also be required to sign our standard confidential information upon the start of your employment.

Such secret or proprietary information shall specifically include, without limitation, all such secret or proprietary information contained in the Company’s manuals, memoranda, plans, drawings and designs, specifications, supply sources, customer lists and records legended or otherwise identified by the Company or the Board as Confidential Information. The Employee’s obligations with respect to Confidential Information will cease when the Confidential Information: (i) becomes part of the public domain through no wrongful act of the Employee, or (ii) is approved for release by prior written authorization of the Company. However, Confidential Information shall be considered Confidential Information even if a portion or specific sections of the Confidential Information are known or generally available to the general public; and the Confidential Information shall not lose its character and status as Confidential Information unless and until all of the Confidential Information is in the public domain.

7.2. Non-Disclosure to Third Parties. Except as required by Employee’s duties, Employee shall not, at any time, now or in the future, directly or indirectly, use, publish, disseminate, reproduce or otherwise disclose any Confidential Information, Concepts and Ideas relating to the present, past or prospective business of the Company to any third party.

7.5. Assignment. The Employee hereby irrevocably assigns and, to the extent any such assignment cannot be made at present, hereby agrees to irrevocably assign to the Company, without further compensation or consideration of her rights, title and interest in and to all Concepts, Ideas, Works, and Inventions and any and all related patents, patent applications, copyrights, copyright applications, licenses, trademarks, trade names and other proprietary or intellectual property rights in the United States and throughout the world. The Employee agrees that she will promptly, without any additional costs, expense or consideration, execute when presented, whether during the Employment Term or at any time thereafter, ail documents, agreements, applications and instruments and perform all lawful acts which the Company considers necessary or advisable to secure its rights hereunder and to carry out the intent of this Agreement.

8. Specific Performance. Employee agrees that any violation by her of Sections 6 or 7 of this Agreement would be highly injurious to the Company and would cause irreparable harm to the Company. By reason of the foregoing, Employee consents and agrees that if she violates or threatens to violate any provision(s) of Sections 6 or 7 of this Agreement, the Company shall be entitled, in addition to any other rights and remedies that it may have, to apply to any court of competent jurisdiction for specific performance and/or injunctive or other equitable relief (without the requirement of posting of a bond or other security) in order to enforce, or prevent any continuing or potential violation of, the provisions of such Section(s). The Employee also recognizes that the territorial, time and scope limitations set forth in Sections 6 and 7, as applicable, are reasonable and are properly required and necessary for the protection of the Company and in the event chat any such territorial, time or scope limitation is deemed to be unreasonable by a court of competent jurisdiction, the Company and the Employee agree, and Employee submits, to the reduction of any or all of said territorial, time or scope limitations to such an area, period or scope as said court shall deem reasonable under the circumstances. If such partial enforcement is not possible, the provision shall be deemed severed, and the remaining provisions of this Agreement shall remain in full force and effect. Employee acknowledges that Sections 6 and 7 of this Agreement shall survive termination or expiration of the Employee’s employment.

9. Termination. Notwithstanding the notice provision of Article 1 hereof, Employee’s employment with the Company: (i) shall terminate upon the Employee’s resignation, death or disability, (ii) may be terminated without prior notice by the Board for Just Cause (as defined herein) and (iii) may be terminated without cause by either party upon twenty (20) days prior notice to the other party as set forth in Article 1 hereof. As used in this Agreement, “Just Cause” means any of the following, as determined by the Board, in its reasonable judgment: (1) Employee’s failure or refusal to perform the duties and responsibilities as are requested of her by the Company; (2) Employee’s negligence or misconduct in the performance of Employee’s duties or (3) the commission by Employee of any act of embezzlement against Company or the commission of any felony or act involving moral turpitude.

Except as hereinafter provided, effective as of the termination or expiration date of the Employee’s employment hereunder for any reason, or for no reason, or in the event the Employee resigns, or her death or disability then, in any of such events, the Employee shall be paid her Base Salary and benefits through the date of expiration or termination and all the rights and options granted to the Employee pursuant to Articles 3 and 4 hereof shall cease and terminate as of the date of the Employee’s termination, expiration or resignation and thereafter shall be null and void and without further force or effect. Notwithstanding anything to the contrary herein contained, it is expressly agreed and understood that (i) if the Employee is terminated by the Company without cause, or the Employee terminates her employment for Good Reason, as hereinafter defined, prior to a “Change of Control” then the Employee shall be entitled to severance payments equal to twelve (12) months continuation of her Base Salary, a pro-rata share of any bonus for which the Employee was eligible, continuation of benefits for the twelve (12) months severance period (or additional compensation in an amount reflecting the cost to the Company of such benefits if the benefit plans do not provide for continuation) and continued vesting of stock options for twelve (12) months. All severance payments of Base Salary and benefits pursuant to subsection (i) will be paid in accordance with the provisions of Articles 3 and 4(a). Alternatively, if the Employee is terminated by the Company without cause, or the Employee terminates her employment for Good Reason, as hereinafter defined, within nine (9) months following a “Change of Control,” the Employee shall be entitled to a one-time severance payment equal to twelve (12) months of her Base Salary as of the date of termination, and such severance payment shall be paid as of the date of termination, If the Employee remains employed by the Company following the nine (9) months after a “Change of Control,” the severance benefits described in subsection (i) shall again apply.

For purposes of this Agreement, “Good Reason” is defined to exist upon:

Provided, however, that any reduction in duties, authority or responsibilities or reduction in the level of management to which the Employee reports resulting solely from a Change in Control which results in the Company being acquired by and made a part of a larger entity shall not constitute Good Reason.

10. Notice. Any notice provided for in this Agreement must be in writing and must be either personally delivered, mailed by first class mail (postage prepaid and return receipt requested), sent by reputable overnight courier service (charges prepaid), or sent by confirmed facsimile at the address indicated below:

or such other address and/or to the attention of such other person as the recipient party shall have designated by notice given in accordance with this Section 10. All notices under this Agreement shall be deemed to have been given: (a) if delivered in person or sent by confirmed facsimile then on the date delivered, (b) if by overnight courier, one (1) day following delivery to recipient, facsimile transmission or delivery to the courier (as the case may be) or (c) if mailed, three (3) business days following deposit in the U.S. mail.

11. Code Section 409 A Compliance.

(a) The intent of the parties is that payments and benefits under this Agreement comply with, or be exempt from Code Section 409A, and, accordingly, this Agreement shall be interpreted and applied so as to be in compliance therewith. The Company and the Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to the Executive under Section 409A.

(b) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment that are considered “non-qualified deferred compensation” under Code Section 409A unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination”, “termination of employment”, or like terms shall mean “separation from service”. If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment that is considered non-qualified deferred compensation under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such “separation from service” of the Executive, and (B) the date of the Executive’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 26(b) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(c) With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Code Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year, provided that the foregoing clause (ii) shall not be

violated with regard to expenses reimbursed under any arrangement covered by Internal Revenue Code Section 105(b) solely because such expenses are subject to a limit related to the period the arrangement is in effect and (iii) such payments shall be made on or before the last day of Executive’s taxable year following the taxable year in which the expense occurred.

For purposes of Code Section 409A, the Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement that is considered nonqualified deferred compensation. In no event shall the timing of Executive’s execution of the General Release, directly or indirectly, result in the Executive designating the calendar year of payment, and if a payment that is subject to execution of the General Release could be made in more than one taxable year, payment shall be made in the later taxable year.

12. Indemnification.

(a) To the fullest extent permitted under applicable law, Employee shall not be liable to the Company or any of its equity holders for any loss, claim, damage or liability arising from any act or omission performed or omitted by the Employee in connection with the Company’s business or affairs (including any error in judgment in providing any advice or counsel), except for any loss, claim, damage or liability primarily attributable to the Employee’s willful misconduct, recklessness, or gross negligence, as finally determined by a court of competent jurisdiction, or as otherwise required by law.

(b) The Company shall, to the fullest extent permitted by applicable law, indemnify and hold the Employee harmless against any and all losses, claims, damages, liabilities, costs or Expenses (as defined below) (including judgments and amounts paid in settlement) to which the Employee may become subject in connection with any matter arising out of or in connection with the Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as a director, officer, employee or agent of another corporation or other enterprise, unless (i) a court of competent jurisdiction, in a judgment that has become final and that is no longer subject to appeal or review, determines that any such loss, claim, damage, liability, cost or Expense is primarily attributable to the Employee’s willful misconduct, recklessness, or gross negligence, or (ii) it is determined in accordance with applicable law that the Employee did not act in good faith and did not reasonably believe that the Employee’s conduct was in or not opposed to the Company’s best interests and, with respect to any criminal Proceeding (as defined below), had no reasonable cause to believe that the Employee’s conduct was unlawful. The termination of a Proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, automatically determinative that Employee did not meet the relevant standard of conduct described in this subsection.

(c) If any Employee becomes involved in any capacity in any Proceeding in connection with any matter arising out of or in connection with the Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as an Executive Chairman, director, officer, employee or agent of another corporation or other enterprise, the Company shall pay (as they are incurred) the Employee’s Expenses (as defined below) incurred in connection therewith after the Company receives (i) a written affirmation by

the Employee of the Employee’s good faith belief that it has met the standard of conduct necessary for indemnification, and (ii) a written undertaking by or on behalf of the Employee to repay to the Company the amount of any such Expense paid to the extent that it is ultimately determined that the Employee is not entitled to be indemnified by the Company in connection with such Proceeding as provided in the exceptions contained herein or under applicable law.

(d) If for any reason (other than anything described in Section 12(b)(i) or (ii)) the foregoing indemnification is unavailable to the Employee, or insufficient to hold it harmless, then the Company shall, to the fullest extent permitted by applicable law, contribute to the amount paid or payable by the Employee as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Employee on the other hand or, if such allocation is not permitted by applicable law, to reflect not only the relative benefits referred to above but also any other relevant equitable considerations.

(e) In any suit brought to enforce a right to indemnification or to recover an advancement of Expenses, the burden of proving that the Employee is not entitled to be indemnified, or to an advancement of Expenses, hereunder is on the Company (or any equity holder of the Company acting derivatively or otherwise on behalf of the Company or its equity holders).

(f) As used in this Agreement,

(i) the term “Proceeding” means (i) any threatened, pending or completed action, suit, arbitration or other alternate dispute resolution mechanism, investigation, inquiry, judicial, administrative or legislative hearing, whether brought by or in the right of the Company or otherwise, including any and all appeals thereof, whether of a civil, criminal, administrative, legislative, arbitrative, investigative or other nature or (ii) any inquiry, hearing or investigation that the Employee reasonably believes might lead to the institution of any such action, suit, alternative dispute resolution mechanism or hearing, whether judicial, administrative or legislative; and

(ii) the term “Expenses” means any and all expenses, including attorneys’ and experts’ fees, court costs and all other expenses, paid or payable in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in (including on appeal), any Proceeding.”

RECITALS

The Company and Employee entered into that certain Employment Agreement dated January 1, 2015 (the “Agreement”);

The Company is seeking a Series C Equity Financing (the “Series C Financing”) and if the Company is successful in completing a Series C Financing, the Board has approved an increase in the base salary of Employee (contingently and only upon the initial closing of such Series C Financing) to $360,000 per annum, with such contingent increase being made (i) effective retroactive to January 1, 2017 and (ii) Employee’s continuous employment through the date of the Series C Financing.

The Company and Employee desire to amend Employee’s employment agreement to provide for such contingent increase.

1. Section 3(a). Base Salary. Section 3(a) is hereby deleted in its entirety and following shall be inserted as a new Section 3(a):

(a) Base Salary. Subject to the provisions of this Agreement, the Company shall pay the Employee a base salary at the initial rate of Three Hundred Fifteen Thousand ($315,000.00) Dollars calculated on an annual basis (the “Base Salary”), which shall be paid in accordance with the Company’s normal payroll procedures and policies. Any adjustments to the Base Salary shall be approved by the Board after discussion with the Employee, provided, however, that the Base Salary may not be reduced. All payments made to the Employee pursuant to this Agreement shall be treated as wages for withholding and employment tax purposes as provided by law, except that reimbursement of expenses will not be so treated to the extent permitted by law. Notwithstanding the foregoing, if the Company successfully completes a Series C Financing, then Employee’s base salary shall be increased to Three Hundred Sixty Thousand ($360,000.00) Dollars calculated on an annual basis, with such contingent increase being made effective retroactive to January 1, 2017, as long as Employee is in continuous employment with the Company through the closing date of the Series C Financing and such increase in the Base Salary is paid in a lump sum no later than March 15 of the year following the year in which the Series C Financing closes.

2. Section 3(b). Cash Bonus. Section 3(b) is hereby deleted in its entirety and following shall be inserted as a new Section 3(b):

(b) Cash Bonus. In addition to the Base Salary, the Employee may be entitled to a bonus of up to Forty (40%) percent of her then Base Salary based upon the successful completion of certain goals and objectives approved by the Board. These goals may relate to the achievement of corporate goals; the achievement of individual goals or a combination of the same. When the goals are agreed to, they shall be identified on Exhibit “A” and added to this Agreement. The decision of the Board as to whether or not the goals have been achieved and the amount of the bonus to be awarded, if any, shall be final and binding on the parties. A bonus, if awarded, shall not be added to the Base Salary and, if awarded, will be paid within forty five (45) days after the end of the year with respect to which the bonus is being awarded.

Except as amended hereunder, all other terms and conditions of the Agreement shall remain in full force and effect. This Amendment may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.
