|12. | Parachute Payment Excise Tax:
|--- | -----------------------------

(a) Subject to paragraph 12(b), in the event that any payments or benefits (within the meaning of Section 280G(b)(2) of the Code) to you or for your benefit, paid or payable or distributed or distributable pursuant to the terms of this
offer letter or otherwise in connection with, or arising out of, your employment with the Company or a Transaction (a Payment or Payments) are deemed parachute payments (as that term is defined in
Section 280G(b)(2) of the Code, but determined without regard to Section 280G(b)(2)(A)(ii)) (the Parachute Payments), would be subject to the excise tax imposed by Code Section 4999, or any interest or penalties are
incurred by you with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the Excise Tax), then you will be entitled to receive an additional payment (a
Gross-Up Payment) in an amount such that after payment by you of all taxes (including any interest or penalties (other than interest and penalties imposed by reason of your failure to file timely a tax return or pay taxes shown due on
your return) imposed with respect to such taxes and the Excise Tax), including any Excise Tax imposed upon the Gross-Up Payment, you retain an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

(b) Notwithstanding any other provision to the contrary, in the event the total amount of Payments does not exceed 110% of the Capped Amount,
no Gross-Up Payment shall be made, and instead the total amount of Payments shall be reduced or limited to the Capped Amount. The reduction of the amounts payable hereunder, if applicable, shall be made by first reducing any cash payments. The
Capped Amount means three (3) times your base amount, within the meaning of Section 280G(b)(3) of the Code, minus one dollar ($1).

(c) You shall notify the Company in writing of the details of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-Up Payment or any
additional Gross-Up Payment as soon as practicable, but

no later than 10 business days after you are informed of such claim. You shall not pay such claim prior to the expiration of the 30-day period following the date on which you give such notice to
the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies you prior to the expiration of such period that the Company desires to contest such claim, you shall permit
the Company to participate in any proceedings relating to such claim in such a manner as determined by the Company in its sole discretion, and fully cooperate with the Company at the Companys expense in good faith in order effectively to
contest such claim in such manner as requested by the Company.

(d) As a result of the uncertainty in the application of
Sections 4999 and 280G of the Code, it is possible that a Gross-Up Payment (or a portion thereof) will be paid which should not have been paid (an Excess Payment).

(e) If an Excess Payment is determined by the applicable government authority to have been made, the amount of the Excess Payment shall be
promptly repaid by you to the Company.

(f) Notwithstanding anything contained in this offer letter to the contrary, in the
event that an Excise Tax will be imposed on any Payment or Payments, the Company shall pay to the applicable government taxing authorities, as Excise Tax withholding, the amount of the Excise Tax that the Company has actually withheld from the
Payment or Payments.

(g) Any Gross-Up Payment payable hereunder shall be made to you no later than the end of the tax year
following the tax year in which you remit payment of the applicable Excise Taxes to the applicable government taxing authority.
