limited to reasonable attorney’s fees) to which the Company may be subject in any action brought by a third party arising out of or relating to a breach or alleged breach by you of any of your representations or warranties set forth above. 

6. Termination Generally. If your employment with WTAM is terminated for any reason other than death, Disability (as defined
below) or for Cause (as defined below), each of WTAM and you agree to discuss and in good faith seek to agree on the substance and wording of any internal and external communications regarding the circumstances of your termination. 

If your employment with WTAM is terminated for any reason (including without limitation death or Disability (as defined below)), WTAM shall pay or provide you
(or to your authorized representative or estate), on or before the time required by law but in any event (i) within ten (10) business days following termination with respect to the amount set forth in clause (a) below,
(ii) upon payment of the annual incentive compensation for the Prior Year to WTAM’s other senior executives with respect to the amount set forth in clause (b) below, provided, however, that you shall not receive any payment pursuant
to clause (b) below if (I) you resign your employment without Good Reason, (II) your employment is terminated by WTAM for Cause, or (III) you received payment, prior to the Date of Termination, of your
incentive compensation for the year (the “Prior Year”) immediately preceding the year in which the Date of Termination occurred (the “Termination Year”); and (iii) promptly after submission of a request for
reimbursement, with appropriate documentation in accordance with WTAM’s policies and procedures then in effect, with respect to the amount set forth in clause (c) below: 

(a) all accrued but unpaid Base Salary through the Date of Termination, 

(b) the “Prior Year Cash Incentive Compensation”, which shall be the lesser of (i) the product of:
(A) the WTI Compensation Committee’s aggregate percentage funding of the Company’s budgeted incentive compensation pool for the Prior Year, multiplied by (B) 50% of your Target Incentive Compensation (as defined below) for the
Prior Year, or (ii) the maximum incentive amount to which you are entitled to under the WisdomTree 2014 Incentive Compensation Plan established pursuant to Code Section 162(m) or similar Section 162(m)
program established by the Compensation Committee for the Prior Year (i.e., the “umbrella plan”) based on achievement of the relevant pre-established goal(s) for the Prior Year (for the avoidance of doubt, the exercise of any negative
discretion permitted thereunder shall be disregarded for this purpose). If you were not employed by the Company for the entirety of the Prior Year, the foregoing amount shall be multiplied by the fraction obtained by dividing the number of days you
were employed by the Company during the Prior Year by 365. 
 (c) reimbursement for reasonable business expenses incurred by you in
performing the services hereunder prior to the Date of Termination, in accordance with the policies and procedures then in effect and established by the Company for its senior executive officers (the “Reimbursement”). 

Your “Target Incentive Compensation” for a fiscal year shall be the average of your actual incentive compensation (including both cash and the fair
value of equity awards at the time of grant; for avoidance of doubt, the fair value of a restricted stock award or a restricted stock unit award that vests over time conditioned solely on continued employment, shall be determined

  
 7 

 
based on the closing price of a share of underlying stock on the date of grant multiplied by the number of shares subject to the award) (x) for the three most recent full fiscal years for
which you have been paid incentive compensation or (y) for such lesser number of full or partial fiscal years for which you have been paid incentive compensation (with any partial fiscal year weighted proportionally less than any full
fiscal year in determining your average incentive compensation; and in the event you never have been paid any incentive compensation for a full or partial fiscal year, your Target Incentive Compensation shall be the target annual incentive
compensation for the Prior Year as may be set forth in your Employment Agreement, or if no such amount is set forth therein, 100% of your annual Base Salary). 

If you initiate or otherwise participate in any arbitration proceeding against the Company to enforce the rights and entitlements granted to you pursuant to
this Paragraph 6 and you substantially prevail in such a proceeding, you shall be entitled to recover from the Company all of your costs of enforcement, including reasonable attorney’s fees and expenses. 

7. Involuntary Termination. Upon your Involuntary Termination and provided you (i) enter into, do not revoke, and comply
with a fully effective Release Agreement materially in the form attached as Exhibit A hereto (the “Release”) and (ii) comply with the Three-Month Restrictive Covenant, WTAM will pay, in the manner set forth below, as severance
to you (or in the case of your subsequent death, the legal representative of your estate or such other person or persons as you shall have designated by written notice to WTAM), an amount equal to sum of: 

(a) the annual Base Salary set forth in Paragraph 1 (the “Annual Base Salary”); 

(b) the “Termination Year Cash Incentive Compensation”, which shall be the lesser of (i) the product of:
(A) the WTI Compensation Committee’s aggregate percentage funding of the Company’s budgeted incentive compensation pool for the Termination Year, multiplied by (B) 50% of your Target Incentive Compensation for the Termination
Year, or (ii) the maximum incentive amount to which you are entitled to under the WisdomTree 2014 Incentive Compensation Plan established pursuant to Code Section 162(m) or similar Section 162(m) program
established by the Compensation Committee for the Termination Year (i.e., the “umbrella plan”) based on achievement of the relevant pre-established goal(s) for the Termination Year (for the avoidance of doubt, the exercise of any negative
discretion permitted thereunder shall be disregarded for this purpose). If you were not employed by the Company for the entirety of the Termination Year, the foregoing amount shall be multiplied by the fraction obtained by dividing the number of
days you were employed by the Company during the Termination Year by 365; and 
 (c) an amount that equals 50% of your Target
Incentive Compensation for the Termination Year (the “Average Cash Incentive Compensation”). 
 In addition, if you elect COBRA insurance
coverage, WTAM directly will pay to you on a monthly basis 100% of the amount of such premiums (the “COBRA Premiums”) for such insurance for twelve months following the Date of Termination, provided that WTAM’s payment
obligation shall cease upon the expiration of your rights under COBRA or if you became reemployed and eligible for group health benefits. 
 The Termination
Year Cash Incentive Compensation shall be paid when WTAM pays to non-terminated senior executives their year-end incentive compensation for the Termination Year, but in no event later than March 15 of the
calendar year following your Date of Termination. The 

  
 8 

 
Annual Base Salary and Average Cash Incentive Compensation shall be paid out in substantially equal bi-monthly or semi-weekly installments in accordance
with WTAM’s payroll practice over twelve months commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a
second calendar year, those amounts shall begin to be paid in the second calendar year. Notwithstanding the foregoing, if you breach any of the provisions contained in Paragraph 4, all payments under this Paragraph 7 shall immediately cease, but you
shall be entitled to retain any payments made to you prior to any breach by you of the provisions of Paragraph 4. 
 If you initiate or otherwise
participate in any arbitration proceeding against the Company to enforce the rights and entitlements granted to you pursuant to this Paragraph 7 and you substantially prevail in such a proceeding, you shall be entitled to recover from the Company
all of your costs of enforcement, including reasonable attorney’s fees and expenses. 
 8. Voluntary Resignation Without
Good Reason or Termination for Cause. If you resign your employment without Good Reason, you shall provide the Company with at least ten (10) business days’ written notice before the effective Date of Termination (the
“Notice Period”). At any time during the Notice Period, or in the event the Company terminates your employment for Cause, the Company may (but shall not be obligated to) elect to invoke the Three-Month Restrictive Covenant by providing you
with written notice of its election (the “Three-Month Restrictive Covenant Election”), via electronic mail, facsimile, overnight mail or in person. If the Company makes the Three-Month Restrictive Covenant Election, then you shall be
subject to the Three-Month Restrictive Covenant for three months following the Date of Termination. In the event the Company provides you with a timely Three-Month Restrictive Covenant Election following your resignation without Good Reason or the
termination of your employment by the Company for Cause, then provided you (I) enter into, do not revoke, and comply with the Release and (II) comply with the Three-Month Restrictive Covenant, WTAM will pay you the sum of:

 (a) 25% of the Annual Base Salary; 

(b) an amount that equals 12.5% of your Target Incentive Compensation for the Termination Year; and 

(c) an amount that equals 25% of the value (determined based on the closing price of a share of the underlying stock on the Date of
Termination multiplied by the number of shares subject to the award) of any equity awards that would have vested in the one year following the Date of Termination if no termination had occurred (assuming for the purpose of this calculation that
during such one year no event (such as a Change of Control) would occur that would provide for the acceleration of vesting under any such equity award). 

This amount shall be paid out in substantially equal bi-monthly or semi-weekly installments in accordance with
WTAM’s payroll practice over three months commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, those amounts shall begin to
be paid in the second calendar year. In addition, if you elect COBRA insurance coverage, WTAM directly will pay to you COBRA Premiums for three months following the Date of Termination provided that WTAM’s payment obligation shall cease
upon the expiration of your rights under COBRA or if you became reemployed and eligible for group health benefits. Notwithstanding the foregoing, if you breach any of the provisions contained in Paragraph 4, all payments under this Paragraph 8 shall
immediately cease, but you shall be entitled to retain any payments made to you prior to any breach by you of the provisions of Paragraph 4. 

  
 9 

 If you initiate or otherwise participate in any arbitration proceeding against the Company to enforce the rights
and entitlements granted to you pursuant to this Paragraph 8 and you substantially prevail in such a proceeding, you shall be entitled to recover from the Company all of your costs of enforcement, including reasonable attorney’s fees and
expenses. 
 9. Change of Control Severance. The provisions of this Paragraph 9 shall apply in lieu of, and expressly
supersede, the provisions of Paragraph 7 regarding severance pay and benefits upon a termination of employment, if such termination of employment occurs within eighteen months after the occurrence of a Change of Control (as defined below). Upon a
Post-Change of Control Termination, and provided you (I) enter into, do not revoke, and comply with the Release and (II) you comply with the Twelve-Month Restrictive Covenant (provided that you shall not be obligated to
comply with the Twelve-Month Restrictive Covenant following the one year anniversary of the Date of Termination), WTAM will pay, in the manner set forth below, as severance to you (or in the case of your subsequent death, the legal representative of
your estate or such other person or persons as you shall have designated by written notice to WTAM): 
 (i) the sum of (A)
1.75 times the Annual Base Salary; (B) an amount determined by multiplying the Average Cash Incentive Compensation by the fraction obtained by dividing the number of days employed by the Company during the Termination Year by 365, and (C) 1.75
times the Average Cash Incentive Compensation. The amounts in this Paragraph 9(i) shall be paid in a lump sum on the first payroll date following the 30th day after the Date of Termination if permissible under Section 409A of the Code
without being subject to additional tax, penalty or surcharge under Section 409A of the Code (it being understood that if a lump sum payment is not permissible thereunder, the amounts under this Paragraph 9(i) shall be paid in the same
schedule as set forth in Paragraph 7 above); 
 (ii) you shall be entitled to accelerated vesting of any unvested portion of
any time-based equity award that would have vested in the twenty-one-month period following the Date of Termination as if no termination had occurred; and 

(iii) If you elect COBRA insurance coverage, WTAM directly will pay to you COBRA Premiums for twenty-one months following the
Date of Termination, provided that WTAM’s payment obligation shall cease upon the expiration of your rights under COBRA or if you became reemployed and eligible for group health benefits. 

Furthermore, the Company agrees to maintain, for a period of at least six years after your termination, directors’ and officers’ liability insurance
insuring you (in your capacity as an officer and/or director) and other officers and directors, with a limit of liability not less than the aggregate of the respective amounts set forth in the policy or policies maintained by the Company immediately
prior to the Change of Control. 
 Notwithstanding the foregoing, if you breach any of the provisions contained in Paragraph 4, all payments under this
Paragraph 9 shall immediately cease, but you shall be entitled to retain any payments made to you prior to any breach by you of the provisions of Paragraph 4. However, if you shall breach the provisions of Paragraph 4(c), the Company shall be
entitled to recover from you a pro-rata portion of the payments made to you under this Paragraph 9 that corresponds to the proportionate period of time that you were in breach of Paragraph 4(c). 

  
 10 

 If you initiate or otherwise participate in any arbitration proceeding against the Company to enforce the rights
and entitlements granted to you pursuant to this Paragraph 9 and you substantially prevail in such a proceeding, you shall be entitled to recover from the Company all of your costs of enforcement, including reasonable attorney’s fees and
expenses. 
 10. Definitions. 

(a) “Cause” shall mean any one or more of the following acts or omissions by you:

(B) to carry out specific legal and lawful directions of a senior officer or the Board of Directors of the Company (in each case other than by reason of Disability);

(ii) above unless you have been given written notice setting forth in reasonable detail the act, omission or failure of, or breach by, you and a period of at least 10 days after such notice to cure all of such acts, omissions, failures or
breaches, and such shall not have been cured within such 10-day period; provided, further, that WTAM shall not be required to give notice and an opportunity to cure for a reason specified in clauses (i)(A) or

 11. Section 409A. 

(a) Anything in this letter to the contrary notwithstanding, if at the time of your separation from service within the meaning of
Section 409A of the Code, the Company determines that you are a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that you become entitled to under
this letter on account of your separation from service would be considered deferred compensation subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of
Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after your separation from service, or
(B) your death. If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for
the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. 

(b) All in-kind benefits provided and expenses eligible for reimbursement under this letter shall be provided by the Company or incurred
by you during the time periods set forth in this letter. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in
which the expense was incurred. The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year.
Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit. 
 (c) To the extent
that any payment or benefit described in this letter constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon your termination of
employment, then such payments or benefits shall be payable only upon your “separation from service.” The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth
in Treasury Regulation Section 1.409A 1(h). 
 (d) The parties intend that this letter will be administered in accordance
with Section 409A of the Code. To the extent that any provision of this letter is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder
comply with Section 409A of the Code. The parties agree that this letter may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and
regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party. 
 (e) The
Company makes no representation or warranty and shall have no liability to you or any other person if any provisions of this letter are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy
an exemption from, or the conditions of, such Section. 
 12. Section 280G. 

Notwithstanding any other provision of this letter or any other plan, arrangement or agreement to the contrary, in the event that: 

(a) the aggregate payments or benefits provided or to be provided by the Company or its affiliates to you or for your benefit pursuant to the
terms of this letter or otherwise that are deemed to be “parachute payments” within the meaning of Section 280G of the Code or any successor thereto (“Change of Control Benefits”) would be deemed to include an “excess
parachute payment” under Section 280G of the Code (or any successor provision thereto); and 

  
 13 

 (b) if such Change of Control Benefits were reduced to an amount (the “Non-Triggering
Amount”), the value of which is one dollar ($1.00) less than an amount equal to three (3) times your “base amount,” as determined in accordance with Section 280G of the Code or (any successor provision
thereto); and 
 (c) (i) the Non-Triggering Amount less the product of the aggregate marginal rate of
any applicable federal, state and local income taxes times the Non-Triggering Amount would be greater than (ii) the aggregate value of the Change of Control Benefits (without such reduction) minus
(x) the aggregate amount of tax required to be paid by you thereon by Section 4999 of the Code (or any successor provision thereto) and any similar excise tax imposed by state or local law and further minus
(y) the product of the Change of Control Benefits times the aggregate marginal rate of any applicable federal, state and local income taxes; then 

(d) the Change of Control Benefits shall be reduced to the Non-Triggering Amount. In such event, the
Aggregate Payments shall be reduced in the following order: (A) cash payments not subject to Section 409A of the Code; (B) cash payments subject to Section 409A of the Code; (C) equity-based
payments and acceleration; and (D) non-cash forms of benefits. To the extent any payment is to be made over time (e.g., in installments, etc.), then the payments shall be reduced in reverse chronological order. 

13. Agreement to Arbitrate. You and the Company agree that all disputes between you and the Company will be resolved by
arbitration as set forth on Appendix B annexed hereto, except as otherwise provided in Appendix B. 
 14. Miscellaneous.
You understand and agree that your employment by WTAM is on at “at will” basis, subject to WTAM’s obligations to pay severance as provided herein. You shall be subordinate to and report directly to officers of WTAM and WTI (or, as may
be indicated, to the WTI Board) set forth on Appendix A. You will be entitled to four weeks paid vacation per year to be accrued on a pro rata basis and you will be entitled to participate in all of the employee benefit plans provided by WTAM
subject to the terms and conditions of those programs. 
 The Company agrees that you shall be permitted to continue to serve as a member of the board of
directors of Barton Mines Corporation (a family-owned company) and ITG (a NYSE: listed company). This letter, together with the 2016 Equity Plan and the Restricted Stock Agreement (as amended herein), and the Indemnification 

Agreement with WTI dated as of the date set forth on Appendix A, set forth all of the terms relating to your employment by WTAM, and supersede all prior
agreements, whether written or oral, including without limitation any prior employment agreement. 
 A signature received via facsimile or PDF will be
deemed an original for all purposes. 
 The rights and obligations of the Company hereunder shall be binding upon and run in favor of the successors and
assigns of the Company. 

  
 14 

 All payments made by the Company to you shall be made net of any tax or other amounts required to be withheld by
the Company under applicable law. Nothing herein or otherwise shall be construed to require the Company to minimize tax consequences to you. 
 This letter
shall be governed by, and construed in accordance with, the internal laws of New York without regard to principles of conflicts of law. 
 This letter may
not be modified or amended, nor may any term or provision be waived unless such modification, amendment or waiver is in writing and signed by the party against whom enforcement of any such modification, amendment or waiver is sought. 

Please indicate by your signature below your agreement with the terms set forth above.

 Appendix B to Employment Letter dated November 27, 2017 

1) Agreement to Arbitrate. You and the Company recognize that differences may arise between them during or following your employment by WTAM. You
understand and agree that by entering into this letter, you anticipate the benefits of a speedy, impartial dispute-resolution procedure of any such differences. As used in this Appendix Band its subparts, the “Company” shall have the
meaning as described in the letter and all successors and assigns of any of them. 
 a) Arbitrable Claims. 

i) ALL DISPUTES BETWEEN YOU (AND YOUR SUCCESSORS AND ASSIGNS) AND THE COMPANY (AND ITS DIRECTORS, OFFICERS, AGENTS AND SUCCESSORS AND ASSIGNS)
RELATING IN ANY MANNER WHATSOEVER TO YOUR EMPLOYMENT BY WTAM OR TO THE TERMINATION THEREOF, INCLUDING WITHOUT LIMITATION ALL DISPUTES ARISING UNDER THIS LETTER, THE STOCK OPTION AGREEMENTS AND THE RESTRICTED STOCK AGREEMENTS (COLLECTIVELY,
“ARBITRABLE CLAIMS”), SHALL BE RESOLVED EXCLUSIVELY BY BINDING ARBITRATION. Arbitrable Claims shall include, but are not limited to, contract (express or implied) and tort claims of all kinds, as well as all claims based on any federal,
state, or local law, statute, or regulation (including but not limited to claims alleging unlawful harassment or discrimination in violation of Title VII and/or Title IX of the U.S. Code, of the Age Discrimination in Employment Act, of the Americans
with Disabilities Act, of state statute, or otherwise), excepting only claims under applicable workers’ compensation law and unemployment insurance claims. Arbitration shall be final and binding upon the parties and shall be the exclusive
remedy for all Arbitrable Claims. Except as provided in Paragraph 1(a)(ii) of this Appendix B, the Arbitrator (as defined below) shall decide whether a claim is an Arbitrable Claim. THE COMPANY AND THE EMPLOYEE HEREBY WAIVE ANY RIGHTS THAT THEY MAY
HAVE TO TRIAL BY JURY IN REGARD TO ARBITRABLE CLAIMS. 
 ii) Notwithstanding anything herein to the contrary, as provided in Paragraph 4(i)
of the letter, the Company may enforce in court, without prior resort to arbitration, any claim concerning a material breach of any of the provisions of Paragraph 4 of the letter. Such court shall determine whether a claim for breach presented by
the Company appropriately invokes the provisions of Paragraph 4. 
 iii) Notwithstanding anything herein to the contrary, as provided in
Paragraph 4(j) of the letter, you may enforce in court, without prior resort to arbitration, any claim seeking indemnification pursuant to the terms of the Indemnification Agreement. 

b) Arbitration Procedure. 

i) American Arbitration Association Rules; Initiation of Arbitration; Location of Arbitration. Arbitration of Arbitrable Claims shall be
in accordance with the Employment Dispute Resolution Rules of the American Arbitration Association (“AAA Rules”), except as provided otherwise in this Appendix B. Arbitration shall be initiated by providing written notice to the other
party with a statement of the claim(s) asserted, the facts upon which the claim(s) are based, and the remedy sought. This notice shall be provided to the other party within six (6) months of the acts or omissions complained of. Any claim not
initiated within this limitations period shall be null and void, and the Company and you waive all rights under statutes of limitation of different duration. The arbitration shall take place in New York, New York. 

  
 17 

 ii) Selection of Arbitrator. All disputes involving Arbitrable Claims shall be decided by
a single arbitrator (the “Arbitrator”), who shall be selected as follows. The American Arbitration Association (“AAA”) shall give each party a list of eleven (11) arbitrators drawn from its panel of employment arbitrators
(the “Name List”). Each party may strike up to six (6) names on the Name List it deems unacceptable, and shall notify the other party of the names it has stricken, within fourteen (14) calendar days of the date the AAA gave
notice of the Name List. If only one common name on the Name List remains unstricken by the parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the Name List unstricken by parties, you shall strike
one of the remaining names and notify the Company, within seven (7) calendar days of notification of the list of unstricken names. If, after you strike a name as set forth in the preceding sentence, there are still two or more unstricken names,
the Company and you shall alternately strike names (with the Company having the next strike) and notify the other party of the stricken name within seven (7) calendar days, until only one remains. If no common name on the initial Name List
remains unstricken by the parties, the AAA shall furnish an additional list or lists, and the parties shall proceed as set forth above, until an Arbitrator is selected. 

iii) Conduct of the Arbitration. 

(1) Discovery. To help prepare for the arbitration, you and the Company shall be entitled, at their own expense, to learn about the
facts of a claim before the arbitration begins. Each party shall have the right to take the deposition of one (1) individual and any expert witness designated by another party. Each party also shall have the right to make requests for
production of documents to any party. Additional discovery may be had only where the Arbitrator so orders, upon a showing of substantial need. At least thirty (30) days before the arbitration, the parties must exchange lists of witnesses,
including any expert witnesses, and copies of all exhibits intended to be used at the arbitration. 
 (2) Authority. The Arbitrator
shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems
necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator
shall apply the substantive law (and the law of remedies, if applicable) of the state in which the claim arose, or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator shall have the authority to award equitable relief,
damages, costs and fees as provided by the law for the particular claim(s) asserted. The Arbitrator shall not have the power to award remedies or relief that a New York court could not have awarded. The Federal Rules of Evidence shall apply. The
burden of proof shall be allocated as provided by applicable law. Except as provided in Paragraph 1(a)(ii) of this Appendix B, the Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any
dispute relating to the interpretation, applicability, enforceability or formation of this Appendix B, including but not limited to any claim that all or any part of any of this Appendix B is void or voidable and any assertion that a dispute between
you and the Company is not an Arbitrable Claim. The arbitration shall be final and binding upon the parties. 
 (3) Costs. Either
party, at its expense, may arrange for and pay the cost of a court reporter to provide a stenographic record of the proceedings. If the Arbitrator orders a stenographic record, the parties shall split the cost. Except as otherwise provided in
Paragraph 1(b)(iii)(6) of this Appendix B, you and the Company shall equally share the fees and costs of 

  
 18 

 
the arbitration and the Arbitrator, and the reference to “the fees and costs of the arbitration and the Arbitrator” in the preceding sentence is not intended to include the fees and
expense of either party’s legal counsel or other advisors, but only the fees and costs imposed on the parties by the AAA in connection with an arbitration conducted under the auspices of the AAA. 

(4) Confidentiality. All proceedings and documents prepared in connection with any Arbitrable Claim shall be confidential and, unless
otherwise required by law, the subject matter thereof shall not be disclosed to any person other than the parties to the proceeding, their counsel, witnesses and experts, the Arbitrator, and, if involved, the court and court staff. All documents
filed with the Arbitrator or with a court shall be filed under seal. The parties shall stipulate to all arbitration and court orders necessary to effectuate fully the provisions of this subparagraph concerning confidentiality. 

(5) Enforceability. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this Appendix B
and to enforce an arbitration award. Except as provided above, neither party shall initiate or prosecute any lawsuit or administrative action in any way related to any Arbitrable Claim. The Federal Arbitration Act shall govern the interpretation and
enforcement of this Appendix B. 
 (6) Limited Right to Attorney’s Fees and Expenses. You and the Company shall be entitled to
an award in their favor by the Arbitrator that includes reimbursement for (i) their costs associated with the fees and costs of the arbitration and the Arbitrator within the meaning set forth in Paragraph 1(b)(iii)(3) of this Appendix B, and
(ii) their reasonable attorney’s fees and expenses in the following circumstances: 
 You: As provided in Paragraph 4(j) of the
letter. 
 You: As provided in Paragraphs 6, 7, 8 and 9 of the letter if you are the substantially prevailing party. 

The substantially prevailing party: As provided in Paragraph 4(i) of the letter

 Exhibit A to Employment Letter dated November 27, 2017 

FORM OF RELEASE AGREEMENT 
 In
consideration for the agreement by WisdomTree Asset Management, Inc. (“WisdomTree”) to provide R. Jarrett Lilien (“Employee”) with the severance payments (the “Severance”) set forth in the Employee’s letter
agreement regarding his employment by WisdomTree dated November 27, 2017 (the “letter”), and for other good and valuable consideration as set forth therein, which Employee hereby acknowledges: 

 

	 	1.	Employee, on behalf of Employee and Employee’s heirs, representatives and assigns, hereby releases and discharges WisdomTree and the WisdomTree Trust and all of their respective subsidiaries, divisions and
affiliated or related companies (collectively, the “Primary Releasees”), and all of the respective current and former directors, officers, stockholders, successors, assigns, agents, representatives and employees of each, and their members,
trustees and attorneys(collectively, the “Secondary Releasees,” and, together with the Primary Releasees, the “Releasees”), of and from (i) any and all claims Employee ever had, now has, or may have in the future against one
or more of the Primary Releasees regarding any matter arising on or before the Effective Date of this release, and (ii) of and from any and all claims Employee ever had, now has, or may have in the future against one or more the Secondary
Releasees regarding any matter arising on or before the Effective Date of this release (but, with respect to this clause (ii), only to the extent that the matter relates to Employee’s employment by WisdomTree), including, without limitation,
all claims regarding Employee’s employment with WisdomTree or the termination thereof, any claim for equitable relief or recovery of monies or damages, claims of breach of contract, wrongful termination, unjust dismissal, defamation, libel or
slander, or under any federal, state or local law dealing with discrimination based on age, race, sex, national origin, handicap, religion, disability or sexual preference, any tort, any claim for wages, any claim for breach of a fair employment
practice law, including, but not limited to, Title VII of the Civil Rights Act of 1964, the Older Workers Benefit Protection Act, the Civil Rights Act of 1991, the Employee Retirement Income Security Act of 1974, the Americans with Disabilities Act,
the Family and Medical Leave Act, the New York State Human Rights Law, the New York City Humans Rights Law, the New York Labor Law, workers compensation laws and any violation of any other local, state or federal law, ordinance or regulation, the
common law and any other purported restriction on an employer’s right to terminate the employment of employees. It is the understanding and agreement of the parties that the release provided by this
sub-paragraph shall be a general release in all respects. Notwithstanding the foregoing, this Release does not extend to: (a) those rights that cannot be waived as a matter of law;
(b) Employee’s right to claim entitlement to the Severance as set forth in the letter; or (c) Employee’s right to indemnification protections as officers and/or directors of WTI and/or any of the Releasees as arising under
contract, statute, regulation, certificates of incorporation or comparable documents of formation, or by-laws or comparable documents of organization. 

 

	 	2.	 Pursuant to and as a part of Employee’s complete, total release and discharge of the Primary Releasees as
set forth in Paragraph 1 above, and as part of Employee’s limited release and discharge of the Secondary Releasees as set forth in Paragraph 1, Employee expressly agrees, to the fullest extent permitted by law, not to sue, file a charge, claim,
complaint, grievance or demand for arbitration in any forum or to assist or otherwise participate willingly or voluntarily in any claim, arbitration, suit, action, charge, complaint, investigation or other proceeding of any kind which relates to
(i) any matter that involves the Primary Releasees and that occurred on or before the Effective Date of this Release and (ii) any matter that involves the Secondary Releasees and relates to Employee’s employment by WisdomTree and that
occurred on or before the Effective Date of this Release. Employee represents that Employee has not filed or initiated any such proceedings against any of the Releasees as of the Effective Date. Nothing in this Release shall be interpreted or
applied to prohibit Employee from making any good faith report to any governmental agency or other governmental entity concerning any acts or omissions that 

  
 20 

	 	
Employee may believe to constitute a possible violation of federal or state law or making other disclosures that are protected under the whistleblower provisions of applicable federal or state
law or regulation. Nothing in this Release shall be construed to prohibit Employee from filing a charge with or participating in any investigation or proceeding conducted by the Equal Employment Opportunity Commission (“EEOC”) or a
comparable state or local agency. Notwithstanding the foregoing, Employee agrees to waive the right to recover monetary damages in any charge, complaint, or lawsuit filed by Employee or by anyone else on Employee’s behalf with the EEOC or a
comparable state or local agency. For the avoidance of doubt, this Release does not limit Employee’s right to receive an award for information provided to any government agency or entity other than the EEOC or a comparable state or local
agency. Except as otherwise provided in this paragraph, Employee will not voluntarily participate in any judicial proceeding of any nature or description against any member of the Releasees that in any way involves the allegations and facts that
Employee could have raised against any member of the Releasees as of the date of this Release. 

  

	 	3.	If forty (40) years of age or older, Employee specifically releases all claims under the Age Discrimination in Employment Act (the “ADEA”) relating to Employee’s employment and its termination.

  

	 	4.	Employee acknowledges that Employee fully understands and agrees that this Release shall operate as a complete defense to any claim or entitlement which hereafter may be asserted by Employee against any and all of the
Releasees for or on account of any matter or thing whatsoever arising out of or in any way based upon the circumstances, facts and events relating to Employee’s employment and separation from employment, or to any claim made by Employee against
any of the Releasees arising from such circumstances, facts and events. 

  

	 	5.	Employee is specifically agreeing to the terms of this release because WisdomTree has agreed to pay Employee money to which Employee was not otherwise entitled under WisdomTree’s policies, and has provided such
other good and valuable consideration as specified herein. WisdomTree has agreed to provide this money and other benefits because of Employee’s agreement to accept it in full settlement of all possible claims Employee might have or ever had
against the Primary Releasees (and the Secondary Releasees as provided in Paragraph 1), and because of Employee’s execution of this Release. 

  

	 	6.	Employee acknowledges and agrees that in the event Employee breaches any continuing obligations pursuant to Paragraph 4 of the letter, WisdomTree may discontinue further Severance payments. For the avoidance of any
doubt, even in such an event, Employee understands and agrees that this Release would remain in full force and effect. 

  

	 	7.	Employee acknowledges that Employee has read this Release in its entirety, fully understands its meaning and is executing this Release voluntarily and of Employee’s own free will with full knowledge of its
significance. Employee acknowledges and warrants that Employee has had ample opportunity to consider the terms and provisions of the Release for at least twenty-one (21) days and that WisdomTree advised
Employee to consult with an attorney prior to executing this Release. If forty (40) years old or older, Employee further acknowledges and agrees that Employee has seven (7) days after executing the Release to revoke Employee’s
signature on the Release, and that the Release does not become valid until the eighth (8th) day after Employee signs the Release without revocation. If Employee wishes to revoke this Release, such
revocation must be in a signed writing and must arrive at WisdomTree to the attention of the Director of Human Resources at 245 Park Avenue, 35th Floor, New York, NY 10167, within the seven
(7) day revocation period.

 David J.
Abner 
 Dear David: 
 We are pleased that you have accepted
the opportunity to work on our behalf in the United Kingdom of Great Britain and Northern Ireland, based in London, for a period of time. This letter will confirm our mutual understanding of the terms and conditions that will apply to your temporary
assignment to London, UK and will also serve to amend your letter agreement, dated February 29, 2008 (“Offer Letter”), with WisdomTree Asset Management, Inc. (the “Company”) to the extent the terms of this letter are
expressly inconsistent with the terms of the Offer Letter. 
  

	I.	Assignment 

  

	A.	Position 

 Your position in London will be the principal executive officer of WisdomTree
Europe Ltd. (“WTE”), with the title “Head of Europe”, reporting to the Board of Directors of WTE and to the Chief Executive Officer of WisdomTree Investments, Inc. (“WTI”) or to such senior officer or committee of
WTI as the Chief Executive Officer of WTI may designate in writing., with duties and responsibilities as the principal executive officer of WTE. Your employer will remain WisdomTree Asset Management, Inc., but you will be providing services to WTE.
This letter does not create a dual, co- or joint employment relationship between the Company and WTE; however, your position may require that you become
“co-employed” by WTE, but without remuneration in addition to that specified below. As part of your duties you will be required to undertake reasonable business travel in Europe to perform your job
functions, and, in addition, you will be required to travel to the United States on occasion, which is presently expected to be approximately four times a year. 
  

	B.	Term 

 The assignment to London will be effective on the first day in the payroll period
immediately following the day you obtain the requisite employment authorization allowing you to work in the United Kingdom (such date, the “Start Date”), and shall last until July 31, 2019 (“Assignment Termination Date”),
unless you and the Company agree in writing to end the assignment on a different date. The assignment will be subject to your obtaining the requisite visa, work permit or other employment authorization allowing you to work and reside in the United
Kingdom. The Company may at any time, at its sole discretion, discontinue or reduce the length of the international assignment subject to the terms outlined in Section VIII of this letter. The terms and conditions of this letter will
only be effective during the period of your assignment. 

	II.	Compensation 

  

	A.	Base Salary 

 Your base salary will be increased to US$300,000 per annum effective as of
the Start Date. Subsequent adjustments to your base salary will be considered at the Company’s sole discretion. You will remain on the United States payroll during the length of your assignment. 

 

	B.	Incentive Compensation 

 You will continue to be eligible for discretionary bonus
consideration, in accordance with the Company’s discretionary bonus plan, based on the Company’s performance, WTE’s performance and on your performance as determined by the Company in its sole discretion; however, provided that you

cash and equity securities of WTI in February, but no later than March 15th, following the applicable fiscal year, consistent with the Company’s policies and procedures. The portion of the
Minimum Guaranteed Bonus for a fiscal year that will be paid in equity securities of WTI shall be determined by the Board of Directors of the Company or its Compensation Committee at its sole discretion, but such portion shall be consistent with the

agreement to be issued to you by WTI. 
  

	III.	Relocation Benefits and Assistance 

 You will be eligible for relocation benefits during
the term of your assignment as outlined below, provided that you are performing services in accordance with the assignment, this letter or as otherwise directed by the Company. 

  
 2 

	A.	Relocation Allowance 

 The Company will provide up to US$25,000 to assist you in moving
you and your family from your home location to the new assignment location. The amount is intended to be applied to the following areas: 
  

	 	•	 	airfares/ground transportation for you and your immediate family members to move from your home location to London; 

  

	 	•	 	shipment of necessary household goods from your current home location to London; 

  

	 	•	 	labor costs associated with packing your household goods for shipment to London and for storage in the United States; 

  

	 	•	 	purchase of necessary household goods for your permanent quarters in London (i.e., for the duration of your relocation by the Company); 

 

	 	•	 	rental of space for the storage of household goods in your home location that you do not wish to move to London (the coverage of which will be for reasonable and customary household and personal goods); and

  

	 	•	 	any temporary housing accommodations for up to fourteen days after your Start Date prior to the move to the permanent quarters, and relocation agent and/or brokerage costs associated therewith. 

The above relocation expenses will either be paid to the vendors either directly by the Company or directly by you. In the event that you pay
for these authorized expenses, you must submit expense reports together with receipts (or other documentation of such expenses which is reasonably acceptable to the Company) for reimbursement. Any submissions for reimbursement should be made on a
timely basis, but in any event no later than February 15th of the calendar year following the calendar year in which the expense is incurred. The relocation benefits provided to you during any
calendar year shall not affect the relocation benefits provided to you in any other calendar year and the right to such relocation benefits cannot be liquidated or exchanged for any other benefit. As indicated above, the total payments paid by the
Company will not exceed US$25,000. Therefore, please plan your move carefully, particularly, in the areas of shipment of household goods, purchase of household goods (i.e. furniture, appliances, etc.) and storage of household goods. 

 

	B.	Work Permits/Visas 

 If legal work authorization is required, it must be granted before
you depart for the United Kingdom. The Company will coordinate assistance for you to obtain the proper work visas/work permits for you and your family. To the extent that you pay any visas or passport filing/application fees personally, you will be
reimbursed by the Company. 

  
 3 

	C.	Housing Allowance 

 The Company will provide you with assistance in identifying permanent
living quarters for you and your family, and, during the term of your assignment, will provide and pay for the rental of an apartment in an area within reasonable commuting distance to the London office, not to exceed GBP15,000 per month (inclusive
of utilities), plus the amount of the annual rental increases provided for in the lease agreement for such apartment. If you elect housing which results in a cost in excess of this allowance, you agree to pay the difference. 

 

	D.	Present U.S. Principal Residence Arrangements 

 You are solely responsible for all costs
and expenses related to your current residence in the United States, including those relating to maintaining such residence, leasing it or selling it. 
  

	E.	Education Costs 

 For primary and secondary schooling, local public (government funded)
schools may not meet the needs for an education process which will prepare your children for re-entry into your local U.S. school system. The Company will pay the cost of private schooling for the local UK
international schools that are adequate in the opinion of the Company, up to an aggregate of GBP72,000 per school year for all of your children, and, in addition, the Company will pay the cost of the annual, reasonable cost increase to such
tuition(s), if any, imposed by such private school(s). If you arrange for private schooling in excess of this, the difference in cost will be your responsibility. 
  

	F.	Cost of Living Adjustment (COLA) 

 You will be provided with an annual stipend, in an
amount as determined by BDO USA LLP, as a cost of living adjustment (“COLA”), payable in equal monthly installments beginning with the month you move into your permanent residence in London. This COLA is intended to compensate you for
differences in living costs and the value of currency in London. On an annual basis, the Company will use data and indices provided through BDO USA LLP to review the COLA amount and will increase the COLA in the event the Company determines that it
should be revised upwards. 
  

	G.	Home Leave 

 The Company will pay the premium coach-class round-trip airfare for you and
your family in London to visit the U.S. twice during each twelve-month period. Note that except with respect to travel on Company business, you must use accrued vacation to the extent you are out of the office. 

 

	H.	Emergency Leave 

 The Company will pay for a premium coach-class round-trip airfare for
you and your family (if necessary) to fly to the United States in the event of a medical emergency concerning, or death of, an immediate family member (i.e., grandparent, parent or sibling) of yours or your spouse. 

  
 4 

	IV.	Other Benefits 

  

	A.	Vacation/PTO 

 Your personal leave benefits will remain the same as present. 

 

	B.	Medical Benefits 

 Medical benefit coverage for you and your immediate family will be
provided during the international assignment. These benefits will be similar to those provided under the current medical benefit program for employees stationed in New York. 
  

	V.	Tax Matters 

  

	A.	Tax Preparation 

 The Company will secure and pay for the services of BDO, USA LLP
(“BDO”) to prepare your U.S. and host country income tax returns for the tax years on which you are on assignment in London. It will be your responsibility to provide all information requested by BDO and to ensure that your tax returns are
accurate and filed when due. You will be responsible to provide, in a timely manner, all reasonable and necessary information to BDO in the form and manner requested to enable them to prepare your U.S. and host country tax returns, as well
as, any other required tax documents. At all times, you will be responsible for the payment of any and all interest or penalties or other assessments associated with untimely or inaccurate submission of data in connection with any tax documentation.

 It is understood that BDO will make such elections, deductions and allocations that will minimize the Company’s obligation for
reimbursement or tax equalization. The Company reserves the right to review the reconciliation and tax returns with BDO. 
 Due to the long
term nature of your assignment, it is your responsibility to ensure that you will qualify for the foreign earned income and housing exclusions. If you anticipate that you will not be able to meet this requirement, please inform the Company and BDO
immediately. 
  

	B.	Tax Equalization 

 The concept of tax equalization is that you will pay approximately no
more or less in total taxes than you would have paid in U.S. (including federal, state and local) income tax, Medicare tax and social security tax on stay-at-home income
such as the Company compensation (i.e. base salary, incentive compensation, etc.) and personal income as a result of your international assignment. Thus under tax equalization, the Company assumes responsibility for the reimbursement of any
“excess U.S. and United Kingdom tax” assessed on income, over and above the “stay-at-home” tax responsibility. Please

  
 5 

 
note, however, that you are solely responsible for any United Kingdom income tax assessed on personal income, including any spousal income. Personal income includes interest, dividends, the gain
on stock or option transactions, pension, or the gain resulting from any transaction involving real estate, such as your principal residence, etc. 

The benefits of the foreign earned income exclusions and Company-paid foreign tax credits will belong to the Company under the Tax Equalization
program. 
 The tax equalization process works as follows: 

During the year, the Company will deduct actual taxes from your compensation. These taxes may include U.S. income tax (federal, state and local
income taxes), U.S. Medicare and social security taxes and taxes assessed by any national, local or other applicable authority in the United Kingdom. Since your assignment is a long term assignment, the federal tax assessed on the Company’s
income will be minimal, due to the foreign earned income exclusions and foreign tax credits (provided you qualify for those exclusions and credits). Likewise, state and local taxes may be minimal due to foreign earned income exclusions and/or any
lack of U.S. permanent residence during your assignment. If you anticipate receiving significant personal income, you should either request that the Company withhold additional tax on any Company compensation or you should pay estimated taxes to the
tax authorities directly to avoid interest and penalties assessed on underpayment of estimated taxes. 
 Your tax equalization calculation
will be prepared by BDO after completion of your U.S. income tax returns. This calculation is intended to reconcile any difference between your stay-at-home tax and the
actual tax you paid during the tax year. If your actual tax payments exceed your stay-at-home tax, you will be entitled to a tax reimbursement from the Company. If the
actual tax payments are less than the stay-at-home-tax, you will be responsible to pay the difference to the Company within 60
days after completion of the tax equalization settlement. 
 Upon the termination of your assignment, the tax equalization will be annualized
and pro-rated based on your actual employment with the Company. 
 BDO’s services are limited to
tax advice directly related to your assignment and do not extend to personal tax advice or financial planning. 
  

	C.	Tax Gross-Up Payment for Housing Allowance and Education Costs 

The payments to be made to you for a Housing Allowance and Education Costs pursuant to Sections III.C and III.E. (and, if any, non-deductible excess relocation costs pursuant to Section IIII.A) hereof shall be increased by a tax “gross-up” payment to take into account (i) all appliacble
federal, state, local and foreign income, employment and excise taxes payable on such amounts, and (ii) the income and employment taxes owing on the “gross-up” payment itself. Such tax gross-up payment shall be made at the same time that payment of the corresponding taxes becoming due. 

  
 6 

	VI.	  PROCESSING AND USE OF EMPLOYEE INFORMATION 

 During your assignment, the
Company will need to process personal data relating to you in order to manage the personal and employment administration spects of your assignment, such as administering payroll, benefits and other services. Therefore, the Company informs you that
your personal data including the sensitive data if collected by the Company (the “Data”), which you provided to the Company, or that it otherwise acquired in the course of the ordinary activity, will be processed as necessary for correct
execution, management and performance of this letter in force between you and the Company. The Data might be communicated, in connection with the above-mentioned purposes, to the Company, its subsidiaries, affiliates, parent, and/or to third-party
service providers which provide assistance and consultancy or other services to the Company, with particular reference, but without limitation, to accounting, administrative, legal, tax and financial issues. These entities are or may be located
outside of the European Union. Such data processing will be performed by means of either manual, electronic or network instruments, or in any other manner that can ensure a safe processing and avoid any unauthorized access. Your personal data will
be kept secure and confidential in accordance with company policy and applicable law. By executing this letter, you expressly authorize and consent to the exports of your Data, even to jurisdictions with data law protections not considered
“adequate” in the country of your assignment, and expressly authorize the transfer, also in non-European Union countries, of your Data to the Company, its subsidiaries, affiliates, parent, and/or
third parties indicated above for the purposes listed in this Section. The Company will regularly update your Data with your assistance and at your request. You will retain the right of access to your Data and the right to have incorrect Data
corrected. The Data provided will not be used for any marketing purposes. 
  

	VII.	  Code of Conduct; and Compliance with Laws 

 You agree that you are bound by,
and during the term of your assignment, will continue to abide by, the provisions of the WTI’s Code of Conduct and Policy Regarding Insider Trading, and the rules, regulations and policies of the Company, in each case as may be amended from
time to time. 
 You also agree that, during the term of your assignment, you will be bound by and abide by the provisions of all applicable
company policies, rules and regulations of WTE, as the same may be amended from time to time, to the same extent as if you were an employee of WTE.

	A.	  Repatriation at Expiration of International Assignment 

 If your
international assignment expires at the Termination Date (or such other date as may be mutually agreed upon), you (and your immediate family) will be repatriated to the U.S. at the Company’s expense (however, you (and your immediate family)
each shall be solely responsible to obtain and possess a valid passport and any visa that may be 

  
 7 

 
necessary so as to enable entry into the U.S.). If your assignment (and employment) does not earlier terminate, and your performance during the assignment has been satisfactory, the Company will,

employment with the Company will terminate. The Company will then provide you with the severance benefits set forth in Section VIII.D below. Out-placement services will be provided through a
Company-approved vendor. 
  

	B.	Early Termination and Termination for Convenience

	C.	Termination of International Assignment for Cause or Due to Resignation

your employment with the Company while on your international assignment, or if the Company terminates your employment for “cause” (as defined below), you (and your immediate family) will not be eligible for any repatriation reimbursement
from the Company.

assignment in London for any reason other than your death or disability or for cause, or (ii) at the expiration of your assignment, as a result of there being no suitable alternative position at the Company at the expiration of the assignment
period pursuant to Section VIII.A above, then, provided you enter into a fully effective release agreement in the form prescribed by the Company within 60 days after your last day of employment, (x) the Company will pay, as severance to you (or
in the case of your subsequent death, the legal representative of your estate or such other person or persons as you shall have designated by written notice to the Company), an amount equal to sum of: (1) the annual base salary set forth in
Section II.A; and (2) the Minimum Guaranteed Bonus set forth in Section II.B (collectively, the “Severance Amount”), and (y) you shall be entitled to accelerated vesting only with respect to the portion of the
outstanding unvested equity awards in the Company’s common stock held by you, if any, that would have vested during the twleve-month period immediately following the date of termination. The Severance Amount shall be paid out in substantially
equal installments in accordance with the Company’s payroll practice over twelve months commencing within sixty days after the date of termination. 

Notwithstanding the foregoing, if you breach any of the restrictive covenants in Section 4 of your Offer Letter, all further payments of
the Severance Amount shall immediately cease.

acceptable to the Company) for reimbursement.

for any specific period or duration. Your employment remains at-will, meaning that either you or the Company may terminate the employment relationship at any time, with or without cause, subject to the terms

 Appendix A to Relocation Letter 

1) Agreement to Arbitrate. You (hereafter referred to as “Employee”) and the Company recognize that differences may arise between them during
or following the Employee’s employment by the Company. The Employee understands that by entering into this letter agreement, the Employee anticipates the benefits of a speedy, impartial dispute-resolution procedure of any such differences. As
used in this Appendix and its subparts, the “Company” shall refer to the Company and all successors and assigns of either of them. 

a) Arbitrable Claims. 
 i)
ALL DISPUTES BETWEEN THE EMPLOYEE (AND HIS OR HER PERMITTED SUCCESSORS AND ASSIGNS) AND THE COMPANY (AND ITS AFFILIATES, STOCKHOLDERS, DIRECTORS, OFFICERS, AGENTS AND PERMITTED SUCCESSORS AND ASSIGNS) RELATING IN ANY MANNER WHATSOEVER TO
EMPLOYEE’S EMPLOYMENT BY THE COMPANY OR TO THE TERMINATION THEREOF, INCLUDING WITHOUT LIMITATION ALL DISPUTES ARISING UNDER THIS LETTER AGREEMENT, EMPLOYEE’S OFFER LETTER OR EMPLOYEE’S ASSIGNMENT (COLLECTIVELY, “ARBITRABLE
CLAIMS”), SHALL BE RESOLVED EXCLUSIVELY BY BINDING ARBITRATION. Arbitrable Claims shall include, but are not limited to, contract (express or implied) and tort claims of all kinds, as well as all claims based on any federal, state, or local
law, statute, or regulation (including but not limited to claims alleging unlawful harassment or discrimination in violation of Title VII and/or Title IX of the U.S. Code, of the Age Discrimination in Employment Act, of the Americans with
Disabilities Act, of state statute, or otherwise), excepting only claims under applicable workers’ compensation law and unemployment insurance claims. Arbitration shall be final and binding upon the parties and shall be the exclusive remedy for
all Arbitrable Claims. Except as provided in Section 1(a)(ii), the Arbitrator (as defined below) shall decide whether a claim is an Arbitrable Claim. THE COMPANY AND THE EMPLOYEE HEREBY WAIVE ANY RIGHTS THAT THEY MAY HAVE TO TRIAL BY JURY IN
REGARD TO ARBITRABLE CLAIMS. 
 ii) Notwithstanding anything herein to the contrary, the Company may enforce in court, without prior resort
to arbitration, any claim concerning actual or threatened unfair competition and/or the actual or threatened use and/or unauthorized disclosure of confidential or proprietary information of the Company. The court shall determine whether a claim
concerns actual or threatened unfair competition and/or the actual or threatened use and/or unauthorized disclosure of confidential or proprietary information of the Company. 

b) Arbitration Procedure. 

i) American Arbitration Association Rules; Initiation of Arbitration; Location of Arbitration. Arbitration of Arbitrable Claims shall be
in accordance with the Employment Dispute Resolution Rules of the American Arbitration Association (“AAA Rules”), except as provided otherwise in this letter agreement. Arbitration shall be initiated by providing written notice to the
other party with a statement of the claim(s) asserted, the facts upon which the claim(s) are based, and the remedy sought. This notice shall be provided to the other party within six (6) months of the acts or omissions complained of. Any claim
not initiated within this limitations period shall be null and void, and the Company and the Employee waive all rights under statutes of limitation of different duration. The arbitration shall take place in New York, New York. 

  
 13 

 ii) Selection of Arbitrator. All disputes involving Arbitrable Claims shall be decided by
a single arbitrator (the “Arbitrator”), who shall be selected as follows. The American Arbitration Association (“AAA”) shall give each party a list of eleven (11) arbitrators drawn from its panel of employment arbitrators
(the “Name List”). Each party may strike up to six (6) names on the Name List it deems unacceptable, and shall notify the other party of the names it has stricken, within fourteen (14) calendar days of the date the AAA gave
notice of the Name List. If only one common name on the Name List remains unstricken by the parties, that individual shall be designated as the Arbitrator. If more than one common name remains on the Name List unstricken by parties, Employee shall
strike one of the remaining names and notify the Company, within seven (7) calendar days of notification of the list of unstricken names. If, after Employee strikes a name as set forth in the preceding sentence, there is still two or more
unstricken names, the Company and the Employee shall alternately strike names (with the Company having the next strike) and notify the other party of the stricken name within seven (7) calendar days, until only one remains. If no common name on
the initial Name List remains unstricken by the parties, the AAA shall furnish an additional list or lists, and the parties shall proceed as set forth above, until an Arbitrator is selected. 

iii) Conduct of the Arbitration. 

(1) Discovery. To help prepare for the arbitration, the Employee and the Company shall be entitled, at their own expense, to learn
about the facts of a claim before the arbitration begins. Each party shall have the right to take the deposition of one (1) individual and any expert witness designated by another party. Each party also shall have the right to make requests for
production of documents to any party. Additional discovery may be had only where the Arbitrator so orders, upon a showing of substantial need. At least thirty (30) days before the arbitration, the parties must exchange lists of witnesses,
including any expert witnesses, and copies of all exhibits intended to be used at the arbitration. 
 (2) Authority. The Arbitrator
shall have jurisdiction to hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person as the Arbitrator deems
necessary. The Arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. The Arbitrator
shall apply the substantive law (and the law of remedies, if applicable) of the state in which the claim arose, or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator shall have the authority to award equitable relief,
damages, costs and fees as provided by the law for the particular claim(s) asserted. The arbitrator shall not have the power to award remedies or relief that a New York court could not have awarded. The Federal Rules of Evidence shall apply. The
burden of proof shall be allocated as provided by applicable law. Except as provided in Section 1(a)(ii), the Arbitrator, and not any federal, state, or local court or agency, shall have exclusive authority to resolve any dispute relating to
the interpretation, applicability, enforceability or formation of this letter agreement and the Offer Letter, including but not limited to any claim that all or any part of any of this letter agreement or the Offer Letter is void or voidable and any
assertion that a dispute between the Employee and the Company is not an Arbitrable Claim. The arbitration shall be final and binding upon the parties. 

  
 14 

 (3) Costs. Either party, at its expense, may arrange for and pay the cost of a court
reporter to provide a stenographic record of the proceedings. If the Arbitrator orders a stenographic record, the parties shall split the cost. Except as otherwise provided in this Appendix, the Employee and the Company shall equally share the fees
and costs of the arbitration and the Arbitrator. The reference to “the fees and costs of the arbitration and the Arbitrator” in the preceding sentence is not intended to include the fees and expense of either party’s legal counsel or
other advisors, but merely the fees and costs imposed on the parties by the AAA in connection with an arbitration conducted under the auspices of the AAA. 

(4) Confidentiality. All proceedings and documents prepared in connection with any Arbitrable Claim shall be confidential and, unless
otherwise required by law, the subject matter thereof shall not be disclosed to any person other than the parties to the proceeding, their counsel, witnesses and experts, the Arbitrator, and, if involved, the court and court staff. All documents
filed with the Arbitrator or with a court shall be filed under seal. The parties shall stipulate to all arbitration and court orders necessary to effectuate fully the provisions of this subparagraph concerning confidentiality. 

(5) Enforceability. Either party may bring an action in any court of competent jurisdiction to compel arbitration under this letter
agreement and to enforce an arbitration award. Except as provided above, neither party shall initiate or prosecute any lawsuit or administrative action in any way related to any Arbitrable Claim. The Federal Arbitration Act shall govern the
