8.    Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such modification, waiver or discharge is agreed to in writing signed by Executive and a duly authorized officer of the Company. No waiver by a party hereto at any time of any breach by the other party hereto of, or of compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement.

9.    Taxes; Set-off. All payments to be made to Executive under this Agreement will be subject to required withholding of federal, state and local income and employment taxes, including any excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (“Code”), or any interest or penalties incurred with respect to such excise tax. The right of Executive to receive benefits under this Agreement, however, shall be absolute and shall not be subject to any set-off, counter-claim, recoupment, defense, duty to mitigate or other rights the Company may have against Executive or anyone else.

10.    Severability. The invalidity and unenforceability of any particular provision of this Agreement shall not affect any other provision of this Agreement, and the Agreement shall be construed in all respects as if the invalid or unenforceable provision were omitted.

11.    Covenant Not to Compete; Non Solicitation; and Confidentiality.

(a)    During the Employment Term and until the third anniversary of the effective date of the termination of Executive’s employment with the Company, Executive shall not:

(i)    engage (whether as an owner, operator, manager, employee, officer, director, consultant, advisor, representative or otherwise) directly or indirectly in any business that produces, develops,

markets or sells any type of food products that compete with those food products produced by the Company; provided however, that ownership of less than ten percent (10%) of the outstanding stock of any publicly-traded corporation (other than the Company) shall not be deemed to be engaging solely by reason thereof in any of the Company’s businesses; or

(ii)    induce or attempt to induce any customer, supplier, lender or other business relation of the Company to cease doing business with the Company or any of its subsidiaries.

(b)    Executive agrees to treat and hold as confidential any information concerning the business and affairs of the Company that is not or does not become generally available to the public other than as a result of a disclosure in violation of this Agreement (the “Confidential Information”), refrain from using any of the Confidential Information except in connection with this Agreement, and deliver promptly to the Company or destroy, at the request and option of the Company, all tangible embodiments (and all copies) of the Confidential Information which are in Executive’s possession.

(c)    Executive acknowledges and agrees that in the event of a breach by Executive of any of the provisions of this Section 11, monetary damages shall not constitute a sufficient remedy. Consequently, in the event of any such breach, the Company or its successor or assigns shall be entitled to, in addition to the other rights and remedies existing in their favor, specific performance and/or injunctive or other relief in order to enforce or prevent any violations of the provisions hereof from any court of competent jurisdiction in each case without the requirement of posting a bond or proving actual damages.

(d)    Executive agrees that except in connection with any legal proceeding relating to the enforcement of this Agreement, following the effective date of the termination of Executive’s employment with the Company, Executive shall not publicly disparage the Company or its officers or directors.

(e)    The term “indirectly” as used in this Section 11 with respect to Executive is intended to mean any acts authorized or directed by or on behalf of Executive or any entity controlled by Executive.

12.    Release of Claims. Executive agrees that in exchange for the payment of all sums due hereunder, Executive forever settles, compromises, discharges, forgives and voids all employment related claims and causes of action Executive has or may have against the Company or its successor or assigns.

13.    Code Section 409A.

(a)    Notwithstanding anything contained herein to the contrary, if at the time of Executive’s termination of employment with the Company for whatever reason, (i) Executive is determined to be a specified employee within the meaning of Section 409A of the Code and the regulations and other guidance thereunder, at the time of such termination and, (ii) any of the payments or benefits provided hereunder may constitute “deferred compensation” under Section 409A of the Code, then the date of payment of such payments or benefits shall be made or begin, as applicable, on the first payroll date which is more than six months following the date of separation from service, to the extent required to avoid any adverse tax consequences under Section 409A of the Code and the regulations and other guidance thereunder.

(b)    To the extent that any right to reimbursement of expenses or payment of any in-kind benefit under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.
