Change-in-Control Severance Agreement



 Exhibit 10.1 
 PRIVILEGED AND CONFIDENTIAL 
 February 3, 2010

 TECO Energy, Inc. (the “Company”) considers it essential to the best interests of its stockholders to foster the
continuous employment of key management personnel. In this connection, the Board of Directors of the Company (the “Board”) recognizes that, as is the case with many publicly held corporations, the possibility of a change in control may
exist and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of key management personnel to the detriment of the Company and its stockholders. 
 The Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members
of the Company’s management, including yourself, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a change in control of the Company. 
 In order to induce you to remain in the employ of the Company and in consideration of your agreement set forth in Subsection 2(iii) hereof,
the Company agrees that you shall receive the severance benefits set forth in this letter agreement (the “Agreement”) in the event your employment with the Company is terminated subsequent to a “change in control of the Company”
(as defined in Section 2(i) hereof) (or is deemed to be terminated subsequent to a change in control of the Company in accordance with the second sentence of Section 3 hereof) under the circumstances described below. This Agreement amends
and restates the letter agreement dated November 1, 2007 between you and the Company (the “Prior Agreement”). 
 1. Term of Agreement. This Agreement shall commence on the date hereof and shall continue in effect through June 30, 2012; provided, however, that commencing on July 1, 2011 and each July 1 thereafter, the term of this
Agreement shall automatically be extended for one additional year unless, not later than March 31 of such year, the Company shall have given notice that it does not wish to extend this Agreement (provided that no such notice may be given during
the pendency of or within two years following a potential change in control of the Company, as defined in Section 2(ii) hereof); provided, further, if a change in control of the Company shall have occurred during the original or extended term
of this Agreement, this Agreement shall continue in effect for a period of thirty-six (36) months beyond the month in which such change in control occurred. 
 2. Change in Control; Potential Change in Control. (i) Except as provided in the second sentence of Section 3 hereof, no benefits shall be payable hereunder unless there shall have been a
change in control of the Company, as set forth below. For purposes of this Agreement, a “change in control of the Company” shall mean a change in control of a nature that would be required to be reported in response to Item 6(e) of
Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), whether or not the Company is in fact required to comply therewith; provided, that, without limitation, such a change in
control shall be deemed to have occurred if: 
 (A) any “person” (as such term is used in Sections
13(d) and 14(d) of the Exchange Act), other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned, directly or indirectly, by the stockholders of the Company in
substantially the same proportions as their ownership of stock of the Company, is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 30% or
more of the combined voting power of the Company’s then outstanding securities; 







 (B) the following individuals cease to constitute a majority of the number
of directors then serving: individuals who on the date hereof constitute the Board and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not
limited to a consent solicitation, relating to the election of directors of the Company) whose election by the Board or nomination for election by the stockholders of the Company was approved by a vote of at least two-thirds (2/3) of the
directors then still in office who either were directors on the date hereof or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or 
 (C) there is consummated a merger or consolidation of the Company or any direct or indirect subsidiary of the Company with
any other corporation, other than (i) a merger or consolidation resulting in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity) at least 50% of the combined voting securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation or (ii) a merger or consolidation
effected to implement a recapitalization of the Company (or similar transaction) in which no “person” (as hereinabove defined) acquires 30% or more of the combined voting power of the Company’s then outstanding securities; or

 (D) the stockholders of the Company approve a plan of complete liquidation of the Company or there is
consummated the sale or disposition by the Company of all or substantially all of the Company’s assets. 
 (ii) For
purposes of this Agreement, a “potential change in control of the Company” shall be deemed to have occurred if: 
 (A) the Company enters into an agreement, the consummation of which would result in the occurrence of a change in control of the Company; 
  

 Page 2 








 (B) any person (as hereinabove defined), including the Company, publicly
announces an intention to take or consider taking actions which if consummated would constitute a change in control of the Company; 
 (C) any person (as hereinabove defined), other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned, directly or
indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company (a) is or becomes the beneficial owner, (b) discloses directly or indirectly to the Company or publicly a plan
or intention to become the beneficial owner, or (c) makes a filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, with respect to securities to become the beneficial owner, directly or indirectly, of securities
representing 9.9% or more of the combined voting power of the outstanding voting securities of the Company; or 
 (D) the Board adopts a resolution to the effect that, for purposes of this Agreement, a potential change in control of the Company has occurred. 
 (iii) You agree that, subject to the terms and conditions of this Agreement, in the event of a potential change in control of the Company during the term of this Agreement (as determined under
Section 1 hereof), you will remain in the employ of the Company until the earliest of (a) a date which is one (1) year from the occurrence of such potential change in control of the Company, (b) the termination by you of your
employment after you attain “normal retirement age” under the provisions of the TECO Energy Group Retirement Plan or any successor thereto (the “Retirement Plan”) or by reason of death or Disability as defined in
Section 3(i), or (c) the date of the occurrence of a change in control of the Company. 
 3. Termination Following
Change in Control. If your employment is terminated following a change in control of the Company and during the term of this Agreement, other than (A) by the Company for Cause, (B) by reason of death or Disability, or (C) by you
without Good Reason, then the Company shall pay you the amounts, and provide you the benefits, described in Section 4(iii) hereof. For purposes of this Agreement, your employment shall be deemed to have been terminated following a change in
control of the Company by the Company without Cause or by you with Good Reason, if (i) your employment is terminated by the Company without Cause prior to a change in control of the Company (whether or not such a change in control ever occurs)
and such termination was at the request or direction of a “person” (as hereinabove defined) who has entered into an agreement with the Company the consummation of which would constitute a change in control of the Company, (ii) you
terminate your employment for Good Reason prior to a change in control of the Company (whether or not such a change in control ever occurs) and the circumstance or event which constitutes Good Reason occurs at the request or direction of such
person, or (iii) your employment is terminated by the Company without Cause or by you for Good Reason and such termination or the circumstance or event which constitutes Good Reason is otherwise in connection with or in anticipation of a change
in control of the Company (whether or not such a change in

  

 Page 3 








 
control ever occurs). Notwithstanding anything in this Agreement to the contrary, you shall not be entitled to the benefits provided in Section 4 hereof unless you have incurred a
“separation from service” under Section 409A of the Code. 
 (i) Disability. If, as a result of your
incapacity due to physical or mental illness, you shall have been absent from the full-time performance of your duties with the Company for six (6) consecutive months, and within thirty (30) days after written notice of termination is
given you shall not have returned to the full-time performance of your duties, your employment may be terminated for “Disability”. 
 (ii) Cause. Termination by the Company of your employment for “Cause” shall mean termination upon (A) the willful and continued failure by you to substantially perform your duties
with the Company (other than any such failure resulting from your incapacity due to physical or mental illness or any such actual or anticipated failure after the issuance of a Notice of Termination by you for Good Reason, as defined in Subsections
3(iv) and 3(iii), respectively) after a written demand for substantial performance is delivered to you by the Board, which demand specifically identifies the manner in which the Board believes that you have not substantially performed your duties,
or (B) the willful engaging by you in conduct which is demonstrably and materially injurious to the Company, monetarily or otherwise. For purposes of this Subsection, no act, or failure to act, on your part shall be deemed “willful”
unless done, or omitted to be done, by you not in good faith and without reasonable belief that your action or omission was in the best interest of the Company. Notwithstanding the foregoing, you shall not be deemed to have been terminated for Cause
unless and until there shall have been delivered to you a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to you and an opportunity for you, together with your counsel, to be heard before the Board), finding that in the good faith opinion of the Board you were guilty of conduct set forth above in this Subsection and
specifying the particulars thereof in detail. 
 (iii) Good Reason. “Good Reason” for termination by you of
your employment shall mean the occurrence (without your express written consent) after any change in control of the Company, or prior to a change in control of the Company under the circumstances described in the second sentence of Section 3
hereof (treating all references in paragraphs (A) through (H) below to a “change in control of the Company” as references to a “potential change in control of the Company”), of any one of the following acts by the
Company, or failures by the Company to act: 
 (A) the assignment to you of any duties inconsistent (except in
the nature of a promotion) with the position in the Company that you held immediately prior to the change in control of the Company or a substantial adverse alteration in the nature or status of your position or responsibilities or the conditions of
your employment from those in effect immediately prior to the change in control of the Company; 
  

 Page 4 








 (B) a reduction by the Company in your annual base salary as in effect on
the date hereof or as the same may be increased from time to time; 
 (C) the Company’s requiring you to be
based more than fifty (50) miles from the Company’s offices at which you were principally employed immediately prior to the date of the change in control of the Company except for required travel on the Company’s business to an extent
substantially consistent with your present business travel obligations; 
 (D) the failure by the Company to pay
to you any portion of your current compensation or compensation under any deferred compensation program of the Company, within seven (7) days of the date such compensation is due; 
 (E) the failure by the Company to continue in effect any material compensation or benefit plan in which you participate
immediately prior to the change in control of the Company unless an equitable arrangement (embodied in an ongoing substitute or alternative plan) has been made with respect to such plan, or the failure by the Company to continue your participation
therein (or in such substitute or alternative plan) on a basis not materially less favorable, both in terms of the amount of benefits provided and the level of your participation relative to other participants, than existed at the time of the change
in control; 
 (F) the failure by the Company to continue to provide you with benefits substantially similar to
those enjoyed by you under any of the Company’s pension, life insurance, medical, health and accident, or disability plans in which you were participating at the time of the change in control of the Company, the taking of any action by the
Company which would directly or indirectly materially reduce any of such benefits or deprive you of any material fringe benefit enjoyed by you at the time of the change in control of the Company, or the failure by the Company to provide you with the
number of paid vacation days to which you are entitled on the basis of your years of service with the Company in accordance with the Company’s normal vacation policy in effect at the time of the change in control of the Company; 
 (G) the failure of the Company to obtain a satisfactory agreement from any successor to assume and agree to perform this
Agreement, as contemplated in Section 6 hereof; or 
 (H) any purported termination of your employment which
is not effected pursuant to a Notice of Termination satisfying the requirements of Subsection (iv) below (and, if applicable, the requirements of Subsection (ii) above), which purported termination shall not be effective for purposes of
this Agreement. 
  

 Page 5 








 Your right to terminate your employment pursuant to this Subsection shall not be affected by your incapacity
due to physical or mental illness. Your continued employment shall not constitute consent to, or a waiver of rights with respect to, any circumstance constituting Good Reason hereunder. 
 (iv) Notice of Termination. Any purported termination of your employment by the Company or by you shall be communicated by written
Notice of Termination to the other party hereto in accordance with Section 7 hereof. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this
Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of your employment under the provision so indicated. 
 (v) Date of Termination, Etc. “Date of Termination” shall mean (A) if your employment is terminated for Disability,
thirty (30) days after Notice of Termination is given (provided that you shall not have returned to the full-time performance of your duties during such thirty (30) day period), and (B) if your employment is terminated pursuant to
Subsection (ii) or (iii) above or for any other reason (other than Disability), the date specified in the Notice of Termination (which, in the case of a termination pursuant to Subsection (ii) above shall not be less than thirty
(30) days, and in the case of a termination pursuant to Subsection (iii) above shall not be less than fifteen (15) nor more than sixty (60) days, respectively, from the date such Notice of Termination is given); provided that if
within fifteen (15) days after any Notice of Termination is given, or, if later, prior to the Date of Termination (as determined without regard to this proviso), the party receiving such Notice of Termination notifies the other party that a
dispute exists concerning the termination, the Date of Termination shall be the date on which the dispute is finally determined, either by mutual written agreement of the parties or by a binding arbitration award; and provided further that the Date
of Termination shall be extended by a notice of dispute given by you only if such notice is given in good faith and you pursue the resolution of such dispute with reasonable diligence. Notwithstanding the pendency of any such dispute, the Company
will continue to pay you your full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, base salary) and continue you as a participant in all compensation, benefit and insurance plans in which
you were participating when the notice giving rise to the dispute was given, until the dispute is finally resolved in accordance with this Subsection. Amounts paid under this Subsection are in addition to all other amounts due under this Agreement
and shall not be offset against or reduce any other amounts due under this Agreement. Notwithstanding anything in this Agreement to the contrary, you shall not be entitled to the benefits provided in Section 4 hereof unless you have incurred a
“separation from service” under Code Section 409A.

 4. Compensation Upon Termination or During Disability. Following a change in control
of the Company, as defined by Subsection 2(i), or prior to a change in control of the Company under the circumstances described in the second sentence of Section 3 hereof, upon termination of your employment or during a period of disability you
shall be entitled to the following benefits: 
 (i) During any period that you fail to perform your full-time duties with the
Company as a result of incapacity due to physical or mental illness, you shall continue to receive your base salary at the rate in effect at the commencement of any such period, together with all compensation payable to you under the Company’s
disability plan or program or other similar plan during such period, until this Agreement is terminated pursuant to Section 3(i) hereof. Thereafter, or in the event your employment shall be terminated by reason of your death, your benefits
shall be determined under the Company’s retirement, insurance and other compensation programs then in effect in accordance with the terms of such programs. 
 (ii) If your employment shall be terminated by the Company for Cause or by you other than for Good Reason, the Company shall pay you your full base salary through the Date of Termination at the rate in
effect at the time Notice of Termination is given, plus all other amounts to which you are entitled under any compensation plan of the Company at the time such payments are due, and the Company shall have no further obligations to you under this
Agreement. 
 (iii) If your employment by the Company terminates in a manner entitling you to benefits under this Section
pursuant to Section 3 hereof, then you shall be entitled to the benefits provided below: 
 (A) the Company
shall pay you your full base salary through the Date of Termination at the rate in effect at the time Notice of Termination is given, plus all other amounts to which you are entitled under any compensation plan of the Company, at the time such
payments are due, except as otherwise provided below; 
 (B) in lieu of any further salary payments to you for
periods subsequent to the Date of Termination, the Company shall pay as severance pay to you a lump sum severance payment (together with the payments provided in paragraphs (C) and (D) below, the “Severance Payments”) equal to
three (3) times the sum of (1) the greater of (a) your annual rate of base salary in effect on the Date of Termination or (b) your annual rate of base salary in effect immediately prior to the change in control of the Company and
(2) your highest annual incentive target award in effect at any time during the 36 months prior to the Date of Termination; 
 (C) for a thirty-six (36) month period after such termination, the Company shall arrange to provide you with life, disability, accident and health insurance benefits substantially similar to those
which you are receiving immediately prior to the Notice of Termination. Benefits otherwise receivable by you pursuant to this Subsection 4(iii)(D) shall be reduced to the extent comparable benefits are actually received by you from a subsequent
employer during the thirty-six (36) month period following your termination, and any such benefits actually received by you shall be reported to the Company. The period during which benefits are provided under this Section shall satisfy the
Company’s obligations to provide continuation coverage under Section 4980B of the Code; and 
  

 Page 7 








 (D) in addition to the retirement benefits to which you are entitled under
the Retirement Plan, any supplemental retirement or excess benefit plan maintained by TECO or any of its subsidiaries or any successor plans thereto (hereinafter collectively referred to as the “Pension Plans”), the Company shall pay you
in cash a lump sum equal to the excess of (a) the actuarial equivalent (computed at your date of termination) of the retirement pension (taking into account any early retirement subsidies and post-retirement surviving spouse benefits associated
therewith and determined as an annuity payable in the normal form under the Pension Plans commencing at your normal retirement age under the Retirement Plan or any earlier date, but in no event earlier than the third anniversary of the Date of
Termination, whichever annuity the actuarial equivalent of which is greatest) which you would have accrued under the terms of the Pension Plans (without regard to the limitations imposed by Section 401(a)(17) of the Code, or any amendment to
the Pension Plans made subsequent to a change in control of the Company and on or prior to the Date of Termination, which amendment adversely affects in any manner the computation of retirement benefits thereunder), determined as if you were fully
vested thereunder and had continued to be a participant in each of the Pension Plans for thirty-six (36) additional months and as if you had accumulated thirty-six (36) additional months of compensation (for purposes of determining your
pension benefits thereunder), each in an amount equal to the sum of the amounts determined under clauses (1) and (2) of Section 4(iii)(B) hereof over (b) the actuarial equivalent (computed at your date of termination) of the
vested retirement pension (taking into account any early retirement subsidies and post-retirement surviving spouse benefits associated therewith and determined as an annuity payable in the normal form under the Pension Plans commencing at your
normal retirement age under the Retirement Plan or any earlier date, but in no event earlier than the Date of Termination, whichever annuity the actuarial equivalent of which is greatest) which you had then accrued pursuant to the provisions of the
Pension Plans. For purposes of this Subsection, “actuarial equivalent” shall be determined using the same actuarial assumptions utilized in determining the amount of alternate forms of benefits under the Retirement Plan immediately prior
to the change in control of the Company. 
 (iv) Except as otherwise specifically provided in paragraph (C) hereof, the
payments provided for in Subsection (iii) shall be made not later than the fifth day following the Date of Termination; provided, however, that if the amounts of such payments cannot be finally determined on or before such day, the Company
shall pay to you on such day an estimate, as determined in good faith by the Company, of the minimum amount of such payments and shall pay the remainder of such payments (together with interest at the rate provided in Section 1274(b)(2)(B) of
the Code) as soon as the amount thereof can be determined but in no event later than the thirtieth day after the Date of Termination. In the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due,
such excess shall constitute a loan by the Company to you payable on the fifth day after demand therefor by the Company (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code). Notwithstanding anything in this

  

 Page 8 








 
Agreement to the contrary, to the extent required by Section 409A of the Code, payment of the amounts payable under this Agreement shall commence no earlier than the earlier of (i) the
first day of the first month commencing at least six (6) months following your separation from service with the Company (within the meaning of Section 409A) or (ii) your date of death. Any amount the payment of which is delayed by
application of the preceding sentence shall be paid as soon as possible following the expiration of such six month period and shall be paid with interest (at an interest rate equal to the rate used to calculate actuarial equivalence in the Pension
Plans) from the date on which such amount would otherwise have been paid but for the application of the preceding sentence to the date such amount is actually paid. To the extent you are terminated (i) following a change in control of the
Company but prior to a change in ownership or control of the Company within the meaning of Section 409A of the Code or (ii) prior to a change in control of the Company in a manner described in the second sentence of Section 3, to the
extent required to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, amounts payable to you hereunder, to the extent not in excess of the amount that you would have received under any other pre-change in control
severance plan or arrangement with the Company had such plan or arrangement been applicable, shall be paid at the time and in the manner provided by such plan or arrangement and the remainder shall be paid to you in accordance with the provisions of
this Section 4; 
 (v) You shall not be required to mitigate the amount of any payment provided for in this Section 4
by seeking other employment or otherwise, nor, except as specifically provided in Sections 4(iii)(C) above, shall the amount of any payment or benefit provided for in this Section 4 be reduced by any compensation earned by you as the result of
employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by you to the Company, or otherwise; and 
 (vi) the Company shall also pay to you all legal fees and expenses incurred by you as a result of or in connection with such termination, including all such fees and expenses, if any, incurred in
contesting or disputing any such termination or in seeking to obtain or enforce any right or benefit provided by this Agreement (other than any such fees or expenses incurred in connection with any such claim which is determined by arbitration, in
accordance with Section 11 of this Agreement, to be frivolous) or in connection with any tax audit or proceeding to the extent attributable to the application of Section 4999 of the Internal Revenue Code of 1986, as amended (the
“Code”), to any payment or benefit provided hereunder. Such payments shall be made within five (5) business days after delivery of your written requests for payment accompanied with such evidence of fees and expenses incurred as the
Company reasonably may require; provided, however, that in no event shall any such payments be made later than the last day of your taxable year following the taxable year in which the fee or expense was incurred. 
 5. Limit on Severance Payments. In the event that (i) any payment or benefit received or to be received by you in connection
with a change in control of the Company or the termination of

  

 Page 9 








 
your employment (whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement with the Company, any person whose actions result in a change in control or any person
affiliated with the Company or such person) (collectively with the Severance Payments, “Total Payments”) would not be deductible (in whole or part) as a result of section 280G of the Code by the Company, an affiliate or other person making
such payment or providing such benefit and (ii) the net amount retained by you, after paying the excise tax imposed by section 4999 of the Code and any federal, state and local income and employment taxes on the Total Payments, would not exceed
the net amount that would have been retained by you after the reduction of the Severance Payments as set forth below and the payment of any federal, state and local income and employment taxes on the Total Payments as so reduced, the Severance
Payments shall be reduced until no portion of the Total Payments is not deductible, or the Severance Payments are reduced to zero. For purposes of this limitation (a) no portion of the Total Payments the receipt or enjoyment of which you shall
have effectively waived in writing prior to the date of payment of the Severance Payments shall be taken into account, (b) no portion of the Total Payments shall be taken into account which in the opinion of tax counsel selected by the
Company’s independent auditors and acceptable to you does not constitute a “parachute payment” within the meaning of section 280G(b)(2) of the Code, (c) the Severance Payments shall be reduced only to the extent necessary so that
the Total Payments (other than those referred to in clauses (a) or (b)) in their entirety constitute reasonable compensation for services actually rendered within the meaning of section 280G(b)(4) of the Code or are otherwise not subject to
disallowance as deductions, in the opinion of the tax counsel referred to in clause (b); and (d) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Company’s
independent auditors in accordance with the principles of sections 280G(d)(3) and (4) of the Code. For purposes of determining the income taxes on the Total Payments, you shall be deemed to pay federal income tax at the highest marginal rate of
federal income taxation in the calendar year in which the Total Payments are to be made and local income taxes at the highest marginal rate of taxation in the state and locality of your residence on the Date of Termination, net of the maximum
reduction in federal income taxes which could be obtained from deduction of such state and local taxes. 
 6. Successors;
Binding Agreement. 
 (i) The Company will require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it
if no such succession had taken place. Failure of the Company to obtain such assumption and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle you to compensation from the Company in the
same amount and on the same terms as you would be entitled to hereunder if you terminate your employment for Good Reason following a change in control of the Company, except that for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Date of Termination. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees
to perform this Agreement by operation of law, or otherwise. 
  

 Page 10 








 (ii) This Agreement shall inure to the benefit of and be enforceable by your personal or
legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If you should die while any amount would still be payable to you hereunder if you had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to your devisee, legatee or other designee or, if there is no such designee, to your estate. 
 7. Notice. For the purpose of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have been duly given when delivered or
mailed by United States registered mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth on the first page of this Agreement, provided that all notices to the Company shall be directed to the attention of
the Board with a copy to the Secretary of the Company, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

 8. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver,
modification or discharge is agreed to in writing and signed by you and such officer as may be specifically designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or 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. The validity, interpretation, construction and performance of this Agreement shall be
governed by the laws of the State of Florida, without giving effect to the conflicts of law principles thereof. All references to sections of the Exchange Act or the Code shall be deemed also to refer to any successor provisions to such sections.
Any payments provided for hereunder shall be paid net of any applicable withholding required under federal, state or local law. The obligations of the Company under Section 4 shall survive the expiration of the term of this Agreement.

 9. Validity. The invalidity or unenforceability or any provision of this Agreement shall not affect the validity or
enforceability of any other provision of this Agreement, which shall remain in full force and effect. 
 10.
Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 
 11. Arbitration. Any dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by
arbitration conducted before a panel of three arbitrators in

  

 Page 11 








 
the State of Florida in accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrator’s award in any court having jurisdiction;
provided, however, that you shall be entitled to seek specific performance of your right to be paid until the Date of Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement. 
 12. Entire Agreement. This Agreement sets forth the entire agreement of the parties hereto in respect of the subject matter contained
herein and during the term of the Agreement supersedes the provisions of all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by any officer, employee or representative of
any party hereto with respect to the subject matter hereof, including the Prior Agreement.
