		Re:	Employment Terms

 

Dear Cheryl:

 

SenesTech,
Inc. (the “Company”) is pleased to offer you continued employment in the position of Chief
Scientific Officer on the following terms of this letter agreement (which is also sometimes referred to as the “Agreement”).

 

1.          Duties
and Responsibilities. As Chief Scientific Officer, you will report to the Company’s Board of Directors (the “Board”).
You will also continue to serve as a member of the Board subject to the terms and conditions of the Company’s Bylaws. You
will work at our facility located in Flagstaff, Arizona. Of course, subject to the terms of this Agreement, the Company may change
your position, duties, and work location from time to time in its discretion. As a Company employee, you will be expected to abide
by Company rules and policies as adopted from time to time, applicable to all officers of the Company.

 

2.          Salary.
Your salary will be $250,000 per year initially, less payroll deductions and withholdings, paid on the Company’s normal payroll
schedule (the “Base Salary”). Your Base Salary will be paid in accordance with the Company’s normal
payroll schedule.

 

3.          Signing
Bonus. The Company agrees to pay you a signing bonus equal to $150,000, less payroll deductions and withholdings, payable within
one (1) business day after the execution of this Agreement by you (the “Signing Bonus”). By signing this
Agreement and accepting the Signing Bonus, you further agree to waive all rights to receive any compensation amounts provided for
in the Executive Employment Agreement dated October 16, 2013, between you and the Company (the “Prior Employment Agreement”).

 

4.          Annual
Bonuses. Each year during your employment, you will be eligible to receive an annual incentive bonus with a minimum target
value equal to thirty-five percent (35%) of your annual Base Salary (each such bonus, an “Annual Bonus”).
Whether you receive an Annual Bonus, and the actual amount of any such bonus, shall be determined by the Board in its sole discretion,
and shall be based upon achievement of performance objectives to be mutually agreed upon between you and the Board (or duly authorized
committee thereof) and other criteria to be determined by the Board. Each Annual Bonus shall be paid within thirty (30) days after
the Board’s determination that an Annual Bonus shall be awarded.

 

    	Page 1 

     

    

  

5.          Restricted
Stock Unit Award. At the first Board meeting following the execution of this Agreement, the Company will grant you an award
of restricted stock units (the “RSU Award”) representing the right to receive 1,100,000 shares of the
Company’s common stock. The RSU Award will vest and be settled over a three-year period, with one third (1/3) of the units
vesting on the twelve (12)-month anniversary of the date of grant, and the remaining units vesting in equal quarterly tranches
over the following twenty-four (24) months of continuous service. The RSU Award shall be issued pursuant to the terms and conditions
of the Company’s 2015 Equity Incentive Plan and the award agreement evidencing the RSU Award, the form of which is attached
hereto as Exhibit C. The RSU Award shall provide that at your election you may satisfy any required employee withholding
taxes due on vesting and settlement of the RSU Award through share withholding.

 

6.          Benefits.
During your employment, you will be eligible to participate in the standard benefits plans offered to similarly situated employees
by the Company from time to time, subject to plan terms and generally applicable Company policies. You will also be eligible to
accrue four weeks of paid vacation and sick leave pursuant to the Company’s standard policies. In addition to these standard
benefits, during your employment the Company will pay the annual premiums (up to $10,000 per year) for a key person term life insurance
policy of $1,000,000, subject to an underwriter’s acceptance. The Company and you will also enter into the Company’s
standard form of Indemnification Agreement in the form attached as Exhibit B.

 

7.          Business
and Travel Expenses. The Company will reimburse you for reasonable out-of-pocket expenses incurred in the performance of your
duties for the Company in accordance with the Company’s rules and policies.

 

8.          Sale
Bonus. In addition to the Signing Bonus, and the Annual Bonus provided above, the Company will pay a transaction bonus in the
amount provided below within 10 days following a Sale of the Company, provided that you are employed by the Company on the date
of such event, equal to: (i) 1% of the Net Sales Price (as defined in Exhibit A) that is $100,000,000 (cash or value of
other property) or less plus an additional (ii) 0.5% of the Net Sales Price that is more than $100,000,000
(cash or value of other property) (the “Sale Bonus”), payable in cash or other proceeds payable to the
Company’s security holders. “Sale of the Company” means a Change in Control (as defined in the
Company’s 2015 Equity Incentive Plan), provided that for the purposes of this Agreement, such definition is hereby revised
to delete the words “(A) on account of the acquisition of securities of the Company directly from the Company,” from
subparagraph (E)(i) thereof. The Sale Bonus is also subject to the additional terms provided in Exhibit A to this Agreement.

 

Notwithstanding the foregoing, if a Sale
of the Company occurs within 12 months following the termination of your employment by the Company without Cause (excluding death
or disability), or your resignation for Good Reason, then you will remain entitled to receive the Sale Bonus, subject to your compliance
with your Employee Confidential Information and Inventions Assignment Agreement and your other obligations under this Agreement
(to the extent then applicable).

 

    	Page 2 

     

    

  

9.          Confidentiality.
In your work for the Company, you will be expected not to use or disclose any confidential information, including trade secrets,
of any former employer or other person to whom you have an obligation of confidentiality. Rather, you will be expected to use only
that information which is generally known and used by persons with training and experience comparable to your own, which is common
knowledge in the industry or otherwise legally in the public domain, or which is otherwise provided or developed by the Company.
You agree that you will not bring onto Company premises any unpublished documents or property belonging to any former employer
or other person to whom you have an obligation of confidentiality. You hereby represent that you have disclosed to the Company
any contract you have signed that may restrict your activities on behalf of the Company. In addition, as a condition of your continued
employment, you continue to be subject to the Employee Confidential Information and Inventions Assignment Agreement previously
entered into with the Company.

 

10.         At-Will
Employment. You may terminate your employment with the Company at any time and for any reason whatsoever simply by notifying
the Company. Likewise, the Company may terminate your employment at any time, with or without cause or advance notice.

 

11.         Severance
Benefits. If, at any time, the Company terminates your employment without Cause, and other than as a result of your death or
disability, and provided such termination constitutes a “separation from service” (as defined under Treasury Regulation
Section 1.409A-1(h)) (a “Separation from Service”), or if you terminate your employment for Good Reason,
you shall be entitled to receive the following severance benefits (the “Severance Benefits”):

 

(a) severance
pay in the form of continuation of your base salary in effect on the effective date of termination for the first 12 months after
the date of such termination;

 

(b) payment
or reimbursement by the Company of COBRA premiums in effect on the date of termination for the coverage in effect for you and,
if applicable, your spouse and dependent children on such date under the Company’s group health plan(s) during the first
12 months after the date of your termination (or, if shorter, until you are no longer entitled to COBRA continuation of coverage
under the Company’s group health plan(s)), provided that you timely (and properly) elect COBRA continuation coverage under
the Company’s group health plan(s) in accordance with Internal Revenue Code Section 4980B(f);

 

(c) any
earned but unpaid Annual Bonus; and

 

(d) an acceleration
of vesting of all outstanding equity awards.

 

For purposes of the above paragraphs, “Cause”
for the Company (or any acquirer or successor in interest thereto) to terminate your employment shall exist if any of the following
occurs: (A) your conviction (including a guilty plea or plea of nolo contendere) of any felony or any other crime involving
fraud, dishonesty or moral turpitude; (B) your commission or attempted commission of or participation in a fraud or act of dishonesty
or misrepresentation against the Company; (C) your intentional, material violation of any written and fully executed contract or
agreement between you and the Company, including without limitation, any Company policy, or of any statutory duty you owe to the
Company; or (D) your conduct that constitutes gross insubordination, incompetence or habitual neglect of duties, provided, however,
that the action or conduct described in clause (C) above and this clause (D) will constitute “Cause” only if such action
or conduct continues after the Board has provided you with written notice thereof and thirty (30) days opportunity to cure the
same (provided that the Board is not obligated to provide such written notice and opportunity to cure if the action or conduct
is not reasonably susceptible to cure). The determination that a termination is for Cause shall be made by the Board in its sole
discretion.  

 

    	Page 3 

     

    

  

For purposes of the above paragraphs, “Good
Reason” for you to terminate your employment shall exist if the following events occur without your prior written
consent: (i) a Sale of the Company; (ii) your assignment to materially reduced duties and responsibilities; (iii) reduction of
your Base Salary or a reduction in benefits; (iv) a relocation of the geographical location at which you must perform services
of more than 25 miles from the location on the date of this Agreement; or (v) a material breach of this Agreement by the Company;
provided that (solely with respect to a termination for Good Reason pursuant to subclauses (ii), (iii) and (v) above) you
must (1) provide written notice to the Board within 90 days after the first occurrence of the event giving rise to Good Reason
setting forth the basis for your resignation, (2) allow the Company 30 days from receipt of such written notice to cure such event,
and (3) if such event is not reasonably cured within such 30-day period, your resignation is effective not later than 90 days after
the expiration of the cure period. 

 

The Severance Benefits are conditional
upon (a) your continuing to comply with your obligations under Company policies with respect to confidential information; and
(b) your delivering to the Company an effective, general release of claims in favor of the Company in a form acceptable to the
Company within 60 days following your termination date. The salary continuation payments described in the above paragraph will
be paid in substantially equal installments on the Company’s regular payroll schedule subject to standard deductions and
withholdings over the period following termination; provided, however, that no payments will be made prior to the 60th day
following your termination, and the first payment shall include all portions of the payments that would have been paid during the
60-day period.

 

12.         Section
409A. It is intended that this Agreement and all payments and benefits provided hereunder satisfy, to the greatest extent possible,
the exemptions from the application of Section 409A of the Internal Revenue Code (the “Code”) provided
under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this Agreement will be construed to the greatest
extent possible as consistent with those provisions. To the extent Code Section 409A is applicable to this Agreement and any such
payments and benefits, the parties intend that this Agreement and such payments and benefits comply with the deferral, payout and
other limitations and restrictions imposed under Code Section 409A. For purposes of Code Section 409A (including, without limitation,
for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), your right to receive installment payments under this Agreement
shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall
at all times be considered a separate and distinct payment. With regard to any provision in this Agreement that provides for reimbursement
of expenses or in-kind benefits, except for any expense, reimbursement or in-kind benefit provided pursuant to this Agreement that
does not constitute a "deferral of compensation," within the meaning of Treasury Regulation Section 1.409A-1(b), (x)
the amount of expenses eligible for reimbursement, or in-kind benefits provided, during any calendar year shall not affect the
expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year, (y) such reimbursements shall
be made on or before the last day of the calendar year following the calendar year in which the expense was incurred, and (z) the
right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit. Notwithstanding
any provision to the contrary in this Agreement, if you are deemed by the Company at the time of your Separation from Service to
be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), to the extent delayed commencement of any
portion of the severance benefits to which you are entitled under this Agreement is required in order to avoid a prohibited distribution
under Code Section 409A(a)(2)(B)(i), such portion of your benefits shall not be provided to you prior to the earlier of (i) the
expiration of the six-month period measured from the date of your Separation from Service with the Company or (ii) the date of
your death. Upon the first business day following the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments
deferred pursuant to this paragraph shall be paid in a lump sum to you, and any remaining payments due under this Agreement shall
be paid as otherwise provided herein.

13.         Miscellaneous.
This letter, together with your Employee Confidential Information and Inventions Assignment Agreement and your Indemnification
Agreement, forms the complete and exclusive statement of your employment agreement with the Company. It supersedes the Prior Employment
Agreement (including any options, warrants or compensation contained therein), and any other agreements or promises made to you
by anyone, whether oral or written. Changes in your employment terms, other than those changes expressly reserved to the Company’s
discretion in this letter, require a written modification signed by you and a member of the Board of Directors. The ongoing obligations
of the Company or you shall survive any of your termination, death or disability. This Agreement and the terms of your employment
with the Company shall be governed in all aspects by the laws of the State of Arizona.

Exhibit A

 

Sale Bonus – Additional Terms

 

1.          Certain
Definitions

 

“Net Sales Price” means
the sum of any cash and the Fair Market Value of any securities or other property, reduced by the Expenses, actually payable to
the Company and/or its securityholders in connection with a Sale of the Company, upon or following the Closing and before taking
into account any payments made under this Agreement or any similar transaction bonus arrangements. The Net Sales Price will include
any Contingent Payments, but will exclude salaries, benefits, bonuses, retention payments, severance arrangements, equity grants
and other compensation provided directly to service providers of the Company by the acquiring entity in connection with the post-closing
employment or other service of such service providers with the acquiring entity and its affiliates.

 

“Contingent Payment” shall
mean any portion of the Net Sales Price actually payable to the Company and/or its securityholders the receipt of which is contingent
upon the passage of time or the occurrence or non-occurrence of future events or circumstances, including without limitation amounts
paid at a subsequent closing, amounts distributed to securityholders as a distribution following an asset sale, and amounts subject
to an escrow, a purchase price adjustment, an earn-out, or indemnity claims, as and when such amounts are paid to the Company’s
securityholders, in each case after reducing such sum by any incremental Expenses associated with the receipt of such amounts.

 

“Expenses” means
the sum of (i) all transaction fees and expenses (including, without limitation, payments to investment bankers and attorneys),
(ii) all debts and liabilities of the Company not assumed by an acquirer of the Company, and (iii) any reserves that the Board
deems reasonably necessary, including a reasonable estimate of post-Closing expenses.

 

“Fair Market Value” means
the value as reasonably determined by the Board (with your abstention) as of the applicable date in accordance with Code Section
409A, if applicable, and such determination will be final and binding.

 

2.          Calculation
and Payment of Sale Bonus Attributable to Contingent Proceeds

 

If any portion of the Sale Bonus is attributable
to a Contingent Payment (the “Contingent Bonus”), such amount will be subject to the same conditions
on payment and potential forfeiture conditions imposed on all other Company securityholders with respect to their rights to such
Contingent Payment, and will be calculated on a pro-rata basis, as determined based on the ratio that your full Sale Bonus (prior
to tax withholdings and deductions) bears to the total Net Sales Price.

 

Any Contingent Bonus will be paid to you within
5 days following payment of the corresponding Contingent Proceeds to the Company’s securityholders.

 

It is intended that the Sale Bonus satisfy,
to the greatest extent possible, the exemption from Code Section 409A provided under Treasury Regulations Section 1.409A-1(b)(4)
and, to the extent not so exempt, that the Sale Bonus comply, and be interpreted to the greatest extent possible as consistent,
with Treasury Regulations Section 1.409A-3(i)(5)(iv)(A) as “transaction-based compensation.”

Dear Tom:

 

SenesTech,
Inc. (the “Company”) is pleased to offer you the position of Chief Financial Officer, on
the following terms.

 

You
will report to Company’s Chief Executive Officer (“CEO”).
You will work with the Board of Directors, and specifically the Audit Committee, in required and traditional capacities.

 

You will work at our facility located
in Flagstaff, Arizona. Of course, the Company may change your position, duties, and work location from time to time in its discretion.

 

Your salary will be $250,000 per
year initially, less payroll deductions and withholdings, paid on the Company’s normal payroll schedule. Your salary may
be paid up to 50% in stock options until the Company is in a financial position to pay it entirely in cash, to be determined by
the CEO.

 

In addition, you will be eligible
for a performance bonus, amounts to be determined at least annually by mutual agreement on the achievement of personal and company
goals. Such bonus amount will be targeted at no less than $200,000 per annum.

 

During your employment, you will
be eligible to participate in the standard benefits plans offered to similarly situated employees by the Company from time to time,
subject to plan terms and generally applicable Company policies. A full description of these benefits is available upon request.
The Company may change compensation and benefits from time to time in its discretion. In
addition to the standard benefits, you will be entitled to 20
days (four weeks) of vacation leave and 10 days (two weeks) of sick leave.
To the extent possible, time off should be scheduled in consultation with your superior in order to minimize the disruption to
the Company’s business. Also, as is the practice for all C-level executives, the Company will provide $1 million in term
life insurance, subject to underwriters’ approval.

 

     

     

    

  

The
Company will grant you an initial option to purchase 600,000 (six hundred thousand) shares of the Company’s common stock
at $0.10 per share, based upon the Company’s current 409A valuation (the “Initial Option”).
The Initial Option will be governed by the terms and conditions of the Company’s 2015 Stock Option Plan (the “Plan”) and your grant agreement, and will include a four year vesting schedule, under which l/48th of the total shares
will vest at the end of each month following the vesting commencement date of December 1, 2015, until either the Initial Option
is fully vested or your continuous service (as defined in the Plan) terminates, whichever occurs first; provided that vesting
shall accelerate in full upon a change of control of the Company. For purposes of the Initial Option (and any restricted stock
purchase agreement if the Initial Option is exercised early), “change of control of the Company” shall
mean: (a) the acquisition of the Company by another entity by means of any transaction or series of related transactions to which
the Company is party (including, without limitation, any stock acquisition, reorganization, merger or consolidation but excluding
any sale of stock for capital raising purposes) other than a transaction or series of transactions in which the holders of the
voting securities of the Company outstanding immediately prior to such transaction continue to retain (either by such voting securities
remaining outstanding or by such voting securities being converted into voting securities of the surviving entity), as a result
of shares in the Company held by such holders prior to such transaction, at least fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity outstanding immediately after such transaction or
series of transactions; (b) a sale, lease or other conveyance of all or substantially all of the assets of the Company; or (c)
any liquidation, dissolution or winding up of the Company, whether voluntarily or involuntarily. For purposes of this agreement
and your Initial Option (and any restricted stock purchase agreement if the Initial Option is exercised early), “cause”
for termination will mean: (a) commission of any felony or crime involving dishonesty; (b) participation in any fraud
against the Company; (c) material breach of your duties to the Company; (d) persistent unsatisfactory performance of job duties
after written notice from the Board and a reasonable opportunity to cure (if deemed curable); (e) intentional damage to any property
of the Company; (f) misconduct, or other violation of Company policy that causes harm; (g) breach of any written agreement with
the Company; and (h) conduct by you which in the good faith and reasonable determination of the Board demonstrates gross unfitness
to serve.

 

The Initial Option may be early
exercised by you by entering into a restricted stock purchase agreement in a form acceptable to the Company that includes a lapsing
repurchase right for the Company to purchase the unvested shares at the original purchase price in the event your continuous service
(as defined in the Plan) terminates, subject, in the case of the Initial Option, to the same acceleration terms in the event of
a change of control of the Company or in connection with a termination of service by the Company without cause in connection with
an initial public offering by the Company.

 

As a Company employee, you will be expected to abide
by Company rules and policies as adopted from time to time. The Company will reimburse you for reasonable expenses incurred in
the performance of your duties for the Company in accordance with the Company’s rules and policies. In addition, the Company
will reimburse submitted receipts for the cost of relocation of household goods to Flagstaff subsequent to but within 12 months
of an IPO.

 

As a condition of employment, you
must sign and comply with the attached Employee Confidential Information and Inventions Assignment Agreement which prohibits unauthorized
use or disclosure of the Company’s proprietary information, among other obligations.

 

In your work for the Company, you
will be expected not to use or disclose any confidential information, including trade secrets, of any former employer or other
person to whom you have an obligation of confidentiality. Rather, you will be expected to use only that information which is generally
known and used by persons with training and experience comparable to your own, which is common knowledge in the industry or otherwise
legally in the public domain, or which is otherwise provided or developed by the Company. You agree that you will not bring onto
Company premises any unpublished documents or property belonging to any former employer or other person to whom you have an obligation
of confidentiality. You hereby represent that you have disclosed to the Company any contract you have signed that may restrict
your activities on behalf of the Company.

 

    Page 2 

     

    

  

Normal business hours are from
9:00 a.m. to 5:00 p.m., Monday through Friday.

 

You may terminate your employment
with the Company at any time and for any reason whatsoever simply by notifying the Company. Likewise, the Company may terminate
your employment at any time, with or without cause or advance notice. Your employment at-will status can only be modified in a
written agreement signed by you and by an officer of the Company.

 

This offer is contingent upon a
reference check and satisfactory proof of your right to work in the United States. You agree to assist as needed and to complete
any documentation at the Company’s request to meet these conditions.

 

To
ensure the rapid and economical resolution of disputes that may arise in connection with your employment with the Company, you
and the Company agree that any and all disputes, claims, or causes of action, in law or equity, including but not limited to statutory
claims, arising from or relating to the enforcement, breach, performance, or interpretation of this Agreement, your employment
with the Company, or the termination of your employment, shall be resolved, to the fullest extent permitted by law, by final,
binding and confidential arbitration in Coconino County, Arizona conducted by JAMS or its successor, under JAMS’ then applicable
rules and procedures for employment disputes. You acknowledge that by agreeing to this arbitration procedure, both you and
the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding. You
will have the right to be represented by legal counsel at any arbitration proceeding. The arbitrator shall: (a) have the authority
to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law;
and (b) issue a written statement signed by the arbitrator regarding the disposition of each claim and the relief, if any, awarded
as to each claim, the reasons for the award, and the arbitrator’s essential findings and conclusions on which the award
is based. The arbitrator shall be authorized to award all relief that you or the Company would be entitled to seek in a court
of law. The Company shall pay all JAMS arbitration fees in excess of the administrative fees that you would be required to pay
if the dispute were decided in a court of law. Nothing in this letter agreement is intended to prevent either you or the Company
from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration.

 

This
letter, together with your Employee Confidential Information and Inventions Assignment Agreement, forms the complete and exclusive
statement of your employment agreement with the Company. It
supersedes any other agreements or promises made to you by anyone, whether oral or written. Changes in your employment
terms, other than those changes expressly reserved to the Company’s discretion in this letter, require a written modification
signed by an officer of the Company.

 

Please sign and date this letter,
and the enclosed Employee Confidential Information and Inventions Assignment Agreement and return them to me if you wish to accept
employment at the Company under the terms described above. If you accept our offer, we would like you to start on December 1, 2015.
