entitled thereunder have been paid in full. For purposes of any calendar year or other period as to which a deferral election relates, the substantive provisions of the Plan that are not specifically modified or amended in a manner permitted under
Section 409A by the Board, whether pursuant to an amendment to the Plan or otherwise, shall continue to be applicable.

the Plan, to make a deferral election within 30 days of first becoming eligible, provided that such a deferral election may relate only to Eligible Cash Compensation attributable to the period following the deferral election. Any change to an
Election may be effective only with regard to Eligible Cash Compensation earned commencing with the next calendar year and only to the extent permitted without penalty in accordance with the requirements of Section 409A. 

ARTICLE III: DEFERRAL OF ELIGIBLE CASH COMPENSATION 

3.1. Establishment of Accounts. The Company shall cause an Account to be kept in the name of each Participant and each Beneficiary of a
deceased Participant who has made an Election with respect to Eligible Cash Compensation, which shall reflect the value of such Participant’s Benefit, as adjusted from time to time to reflect Credited Investment Return (Loss). 

3.2. Crediting of Accounts. Except as otherwise determined by the Board, the Company shall credit to each Participant’s Account a
notional amount equal to the gross amount of the Eligible Cash Compensation deferred under the Plan. 
 3.3. Vesting. Except as
otherwise determined by the Board in advance of the Election deadline, amounts credited to an Account in respect of Eligible Cash Compensation (and the earnings (losses) credited thereon) shall be 100% vested. 

3.4. Credited Investment Return (Loss). Except as otherwise determined by the Board, the Account shall be credited with any earnings
(or losses) in accordance with investments designated by the Board after consultation with the Participant. For the avoidance of doubt, the Board shall not be bound by any investment preferences of the Participant. 

3.5. Timing of Distribution. The vested portion of a Participant’s Account shall be paid (or payment shall commence) in accordance
with the terms of the Participant’s Election. 
 3.6. Method of Distribution. Except as otherwise determined by the Board and/or

ARTICLE IV: BENEFICIARIES

 4.2. No Designated Beneficiary. If, upon the death of the Participant, there is no
valid designation of a Beneficiary, the Beneficiary shall be the Participant’s estate. 
 ARTICLE V: ADMINISTRATION OF THE PLAN

 This Plan shall be administered by the Board (excluding any Participants). The Board has sole discretion to interpret the Plan and to
determine all questions arising in the administration, interpretation, and application of the Plan. The Board’s powers include the power, in its sole discretion and consistent with the terms of the Plan, to determine who is eligible to
participate in this Plan, to determine the eligibility for and the amount of benefits payable under the Plan, to establish rules for determining when and how elections can be made, to adopt any rules relating to administering the Plan and to take
any other action it deems appropriate to administer the Plan. The Board may delegate its authority hereunder to one or more officers of the Company. Whenever payments are to be made under this Plan, such payments shall be made consistent with the
terms of the applicable Election and no interest shall be paid on such amounts for any reasonable delay in making the payments. The Board’s decisions under the Plan shall be final and binding on all Participants, as well as the
Participant’s heirs, assigns, administrator, executor, and any other person claiming through the Participant. This Plan shall be interpreted and administered in a manner that complies with Section 409A. 

ARTICLE VI: MISCELLANEOUS 

6.1. The right of a Participant or his or her designated Beneficiary to receive a distribution hereunder shall be an unsecured claim against
the general assets of the Company, and neither the Participant nor a designated Beneficiary shall have any rights in or against any specific assets of the Company. The contents of each Account shall be considered assets of the Company until
distributed to a Participant or his or her designated Beneficiary. This Plan shall not be construed to require the Company to fund, prior to payment, any amounts payable under this Plan. 

6.2. If, in the Company’s opinion, a Participant or Beneficiary for any reason is unable to handle properly any payments payable to him or
her under the Plan, then the Company may make such arrangements which it determines to be beneficial to such Participant or Beneficiary, to the extent such arrangements have not been made by such Participant or Beneficiary, for the distribution of
such payment, including (without limitation) the distribution of such payment to the guardian, conservator, spouse or dependent(s) of such Participant or Beneficiary. 

6.3. The right of any Participant, any Beneficiary, or any other person to the payment of any amounts under this Plan shall not be assigned,
transferred, pledged or encumbered. 
 6.4. This Plan shall be binding upon and inure to the benefit of the Company, its successors and
assigns and the Participant and his heirs, executors, administrators and legal representatives. 
 6.5. Nothing contained herein shall be
construed as conferring upon any Participant the right to continue in the service of the Company as a member of the Board of Directors. Nothing in this Plan or any Benefits shall in any way interfere with or limit the right of the Company, or any
affiliate of the Company, to terminate any Participant’s status as a member of the Board of Directors at any time, as applicable, or confer upon any Participant any right to continue in the service of the Company or any affiliate of the
Company.

 6.6. If the Company, the Participant, any Beneficiary, or a successor in interest to any of
the foregoing, brings legal action to enforce any of the provisions of this Plan, the prevailing party in such legal action shall be reimbursed by the other party for the prevailing party’s costs of such legal action including, without
limitation, reasonable fees of attorneys, accountants and similar advisors and expert witnesses. 
 6.7. This Plan shall be governed and
construed in accordance with the laws of the State of Delaware (regardless of the law that might otherwise govern under applicable principles of conflict of laws) except to the extent the laws of the State of Delaware are superseded by or conflict
with Applicable Law. 
 6.8. This Plan constitutes the entire understanding and agreement with respect to the subject matter contained
herein, and there are no agreements, understandings, restrictions, representations or warranties among a Participant and the Company other than those set forth or provided for herein. 

6.9. If any provision of this Plan is held to be illegal or invalid for any reason, that illegality or invalidity shall not affect the
remaining portions of this Plan, but such provision shall be fully severable and this Plan shall be construed and enforced as if the illegal or invalid provision had never been included in this Plan. Such an illegal or invalid provision shall be
replaced by a revised provision that most nearly comports to the substance of the illegal or invalid provision. If any of the terms or provisions of this Plan or any Election conflict with the requirements of Applicable Laws, those conflicting terms
or provisions shall be deemed inoperative to the extent they conflict with Applicable Law. In the event of any conflict or ambiguity between an Election and the Plan, the terms of the Plan shall govern. 

6.10. No person constituting, or member of the group constituting, the Board shall be liable for any act or omission on such person’s
part, including but not limited to the exercise of any power or discretion given to such member under this Plan, except for those acts or omissions resulting from such member’s gross negligence or willful misconduct. The Company shall indemnify
each present and future person constituting, or member of the group constituting, the Board against, and each person or member of the group constituting the Board shall be entitled without further act on his or her part to indemnity from the Company
for, all expenses (including the amount of judgments and the amount of approved settlements made with a view to the curtailment of costs of litigation) reasonably incurred by such person in connection with or arising out of any action, suit or
proceeding to the fullest extent permitted by law and by the Charter and Bylaws of the Company. 
 6.11. The Company shall have the right to
deduct from any payment to be made to a Participant, or to otherwise require, prior to the payment of any cash hereunder, payment by the Participant of, any federal, state or local taxes required by law to be withheld. In addition, on the occurrence
of any event with respect to any Eligible Cash Compensation deferred pursuant to this Plan that requires the Company to withhold taxes, the Participant shall make arrangements satisfactory to the Company whereby such taxes may be paid.

 6.12. The Board may at any time amend, suspend or discontinue this Plan, provided that such
amendment, suspension or discontinuance meets the requirements of Applicable Laws, including without limitation, any applicable requirements for stockholder approval. Notwithstanding the above, an amendment, suspension or discontinuation shall not
be made if it would substantially impair the rights of any Participant under any Benefits previously granted in connection with a deferral of Eligible Cash Compensation elected by a Participant pursuant to this Plan, without the Participant’s
consent, except to conform this Plan and any Benefits granted in connection with this Plan to the requirements of Applicable Laws. 
 6.13.
Claims and Appeals. 
 (a) Claims Procedure. The Participant or any other person who believes he or she is entitled to any
payment under the Plan may submit a claim in writing to the Board within ninety (90) calendar days of the earlier of (i) the date the claimant learned the amount of his benefits under the Plan or (ii) the date the claimant learned
that he or she will not be entitled to any benefits under the Plan. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the
Plan on which the denial is based. The notice also will describe any additional information needed to support the claim and the Plan’s procedures for appealing the denial. The denial notice will be provided within ninety (90) calendar days
after the claim is received. If special circumstances require an extension of time (up to ninety (90) calendar days), written notice of the extension will be given within the initial ninety (90) day period. This notice of extension will
indicate the special circumstances requiring the extension of time and the date by which the Board expects to render its decision on the claim. 

(b) Appeal Procedure. If the claimant’s claim is denied, the claimant (or his authorized representative) may apply in writing to
the Board for a review of the decision denying the claim. Review must be requested within sixty (60) calendar days following the date the claimant received the written notice of their claim denial or else the claimant loses the right to review.
The claimant (or representative) then has the right to review and obtain copies of all documents and other information relevant to the claim, upon request and at no charge, and to submit issues and comments in writing. The Board will provide written
notice of its decision on review within sixty (60) calendar days after it receives a review request. If additional time (up to sixty (60) calendar days) is needed to review the request, the claimant (or representative) will be given
written notice of the reason for the delay. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Board expects to render its decision. If the claim is denied (in full or in part),
the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Plan on which the denial is based. The notice also will include a statement that the claimant will be provided, upon
request and free of charge, reasonable access to, and copies of, all documents and other information relevant to the claim and a statement regarding the claimant’s right to bring an action under Applicable Law.

 ARTICLE VII: SECTION 409A 

7.1. Although the Company does not guarantee the particular tax treatment of any Benefits in connection with a deferral of Eligible Cash
Compensation under the Plan, such Benefits are intended to comply with, or be exempt from, the applicable requirements of Section 409A and the Plan and any Election made hereunder shall be limited, construed and interpreted in accordance with
such intent. In no event whatsoever shall the Company or any of its affiliates be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 409A or any damages for failing to comply with
Section 409A. 
 7.2. Notwithstanding anything in the Plan or in an Election to the contrary, the following provisions shall apply to
any Benefits in connection with a deferral of Eligible Cash Compensation under the Plan that constitute “non-qualified deferred compensation” pursuant to Section 409A. A termination of service
shall not be deemed to have occurred for purposes of any provision of this Plan or an Election providing for payment upon or following a termination of the Participant’s service unless such termination is also a “separation from
service” within the meaning of Section 409A and, for purposes of any such provision, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.”
Notwithstanding any provision to the contrary in the Plan or the Election, if the Participant is deemed on the date of the Participant’s termination to be a “specified employee” within the meaning of that term under
Section 409A(a)(2)(B) of the Code and using the identification methodology selected by the Company from time to time, or if none, the default methodology set forth in Section 409A, then with regard to any payment due upon a
“separation from service,” to the extent required to be delayed in compliance with Section 409A(a)(2)(B) of the Code, such payment shall not be made prior to the earlier of (i) the expiration of the six (6)-month period measured
from the date of the Participant’s “separation from service,” and (ii) the date of the Participant’s death. All payments delayed pursuant to this Section 7.2 shall be paid to the Participant on the first day of the
seventh month following the date of the Participant’s “separation from service” or, if earlier, on the date of the Participant’s death. Whenever an Election specifies a payment period without reference to a particular date, the
actual date of payment within the specified period shall be within the sole discretion of the Company.
