 14. Equitable Remedies; Availability of Other Remedies; Obligations Absolute.

 (a) Executive represents and warrants that Executive has had an opportunity to consult with an attorney regarding this
Agreement, has thoroughly and completely reviewed this Agreement with an attorney, and fully understands the contents hereof. 

(b) Executive acknowledges that (i) the provisions of Sections 12 and 13 are reasonable and necessary to protect the legitimate
interests of the Corporation and its Affiliates, and (ii) any violation of Sections 12 or 13 will result in irreparable injury to the Corporation, the exact amount of which will be difficult to ascertain, and that the remedies at law for any
such violation would not be reasonable or adequate compensation to the Corporation and its Affiliates for such a violation. Accordingly, Executive agrees that if Executive violates the provisions of Sections 12 or 13, in addition to any other remedy
which may be available at law or in equity, the Company and its Affiliates shall be entitled to specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual damages.

misappropriation of trade secrets, under other laws and common law requirements and under all applicable rules and regulations. 

(d) Executive’s obligations under this Agreement are absolute and shall not be terminated or otherwise limited by virtue of any
breach (on the part of the Corporation or any other person) of any provision of any other agreement, or by virtue of any failure to perform or other breach of any obligation of the Corporation, the Company, or any other person.

permitted by law, this Agreement shall be interpreted in such a manner that all payments to Executive under this Agreement are either exempt from, or comply with, Section 409A of the Code and the regulations and other interpretive guidance
issued thereunder (collectively, “Section 409A”), including without limitation any such regulations or other guidance that may be issued after the CEO Employment Date. It is intended that payments


  
 -13-









 
under this Agreement will be exempt from Section 409A, including the exceptions for short-term deferrals, separation pay arrangements, reimbursements, and in-kind distributions, so as not to
subject the Executive to payment of interest or any additional tax under Section 409A. To the extent any reimbursements or in-kind benefit payments under this Agreement are subject to Section 409A, such reimbursements and in-kind benefit
payments shall be made in accordance with Treasury Regulation §1.409A-3(i)(1)(iv) (or any similar or successor provisions). In furtherance thereof, if the provision of any reimbursement or in-kind benefit payment hereunder that is subject to
Section 409A at the time specified herein would subject such amount to any additional tax under Section 409A, the provision of such reimbursement or in-kind benefit payment shall be postponed to the earliest commencement date on which the
provision of such amount could be made without incurring such additional tax. In addition, to the extent that any regulations or other guidance issued under Section 409A (after application of the previous provisions of this Section 15)
would result in the Executive’s being subject to the payment of interest or any additional tax under Section 409A, the parties agree, to the extent reasonably possible, to amend this Agreement to the extent necessary (including
retroactively) in order to avoid the imposition of any such interest or additional tax under Section 409A, which amendment shall have the minimum economic effect necessary and be reasonably determined in good faith by the Corporation and the
Executive. Executive acknowledges and agrees that the Corporation has made no representation to Executive as to the tax treatment of the compensation and benefits provided pursuant to this Agreement and that Executive is solely responsible for all
taxes due with respect to such compensation and benefits. 
 16. PARACHUTE PAYMENTS.
If any payment or benefit Executive would receive from the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue
Code of 1986, as amended (the “Code”), and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be reduced to the Reduced Amount. The
“Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment,
whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive’s receipt, on an after-tax
basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment
equals the Reduced Amount, reduction shall occur in the following order: reduction of cash payments; cancellation of accelerated vesting of stock awards; reduction of employee benefits. In the event that acceleration of vesting of stock award
compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of Executive’s stock awards. 
 17. Successors. This Agreement is personal to the Executive and may not be assigned by the Executive other than by will or the laws of descent and distribution. This Agreement will inure to
the benefit of and be enforceable by the Executive’s legal representatives or successors in interest. Notwithstanding any other provision of this Agreement, the Executive may designate a successor or successors in interest to receive any
amounts due 

  
 -14-









 
under this Agreement after the Executive’s death. If he has not designated a successor in interest, payment of benefits under this Agreement will be made to his wife, if surviving, and if
not surviving, to his estate. A designation of a successor in interest must be made in writing, signed by the Executive, and delivered to the Corporation pursuant to Section 20. Except as otherwise provided in this Agreement, if the Executive
has not designated a successor in interest, payment of benefits under this Agreement will be made to the Executive’s estate. This Section will not supersede any designation of beneficiary or successor in interest made by the Executive or
provided for under any other plan, practice, or program of the Corporation. 
 This Agreement will inure to the benefit of and
be binding upon the Corporation and its successors and assigns. 
 The Corporation will require any successor (whether direct or
indirect, by acquisition of assets, merger, consolidation or otherwise) to all or substantially all of the operations or assets of the Corporation or any successor and without regard to the form of transaction used to acquire the operations or
assets of the Corporation, to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform it if no succession had taken place. As used in this Agreement,
“Corporation” means the Corporation and any successor to its operations or assets as set forth in this Section that is required by this clause to assume and agree to perform this Agreement or that otherwise assumes and agrees to perform
this Agreement. 
 18. Failure, Delay or Waiver. No course of action or failure to act by the Corporation or the
Executive will constitute a waiver by the party of any right or remedy under this Agreement, and no waiver by either party of any right or remedy under this Agreement will be effective unless made in writing. 

19. Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any
jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment
of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific
words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this
Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable
term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term. 
 20. Notice. All written communications to a party required hereunder shall be in writing and (a) delivered in person (to be effective when so delivered), (b) mailed by registered
or certified mail, return receipt requested (to be effective four days after the date it is

deposited in the U.S. Mail), (c) deposited with a reputable overnight courier service (to be effective two business days after the delivery to such courier service), or (d) sent by
