 (a) Base Salary. During the Executive’s continued employment hereunder, the Company shall pay the Executive a
base salary (the “Base Salary”) at the annualized rate of $171,164, which shall be subject to customary withholdings and authorized deductions and be payable in equal installments in accordance with the Company’s customary
payroll practices in place from time to time. The Executive’s Base salary shall be subject to periodic adjustments as the Board and/or the Compensation Committee of the Board (the “Compensation Committee”) shall in its/their
discretion deem appropriate. As used in this Agreement, the term “Base Salary” shall refer to Base Salary as may be adjusted from time to time. Executive acknowledges and agrees that, although his regularly scheduled work hours are
limited to three (3) full days per week, as an exempt employee, the Executive (i) will be expected to work during his regularly scheduled hours, as well as, from time to time and as mutually agreed between the Executive and the President

days per week. 
 (b) Annual Bonus. For each calendar year ending during the Executive’s continued employment with

Salary earned by the Executive for such calendar year. The actual amount of each Annual Bonus will be based upon the level of achievement of the Company’s corporate objectives and the Executive’s individual objectives, in each case, as
established by the Board or the Compensation Committee (taking into account the input of the CEO with respect to the establishment of the Executive’s individual objectives) for the calendar year with respect to which such Annual Bonus relates.
The determination of the level of achievement of the corporate objectives and the Executive’s individual performance objectives for a year shall be made by the Board or the Compensation Committee (taking into account the input of the CEO with
respect to the level of achievement of the Executive’s individual objectives), in its reasonable discretion. Each Annual Bonus for a calendar year, to the extent earned, will be paid in a lump sum in the following calendar year, within the
first 75

actively employed by the Company at the time of such payment.

Company’s 2004 Equity Compensation Plan, as amended (the “2004 Plan”), the Executive was granted options to purchase shares of the Company’s common stock (the “Prior Grants”) pursuant to the terms of stock

Section 4.4 hereof, nothing in this Agreement shall be deemed to alter, limit or abrogate the terms of the Prior Grant Agreements or the Executive’s rights with respect to the Prior Grants. During the period of the Executive’s
continued employment hereunder, subject to the terms and conditions established within the Company’s 2013 Equity Compensation Plan or any successor equity compensation plan as may be in place from time to time (the “2013 Plan”)
and separate Award Agreements (as defined in the 2013 Plan), the Executive also shall be eligible to receive from time to time additional Stock Options, Stock Units, Performance Shares, Performance Units, Incentive Bonus Awards, Other Cash-Based
Awards and/or Other Stock-Based Awards (as such capitalized terms are defined in the 2013 Plan), in amounts, if any, to be approved by the Board or the Compensation Committee in its discretion. 

(d) Benefit Plans. As a part-time employee regularly scheduled to work only three (3) days per week, the Executive is not
eligible to participate in the Company’s group health insurance or flexible spending plans, but is eligible to participate in the Company’s 401(k) plan (to the extent permissible under the general terms and provisions of such plan and in
accordance with the provisions thereof). The Company may amend, modify or rescind any employee benefit plan or program without notice in its discretion. 
 (e) Paid Vacation. The Executive shall be entitled to paid vacation days in accordance with the Company’s vacation policies in effect from time to time; provided, however, that the
Executive shall be entitled to no less than twelve (12) paid vacation days per calendar year during his continued employment.

Company requests that the Executive provide notice of his resignation at least two (2) weeks prior to the effective date of his resignation; provided, however, the Company
reserves the right, upon written notice to the Executive, to accept the Executive’s notice of resignation and to accelerate such notice and make the Executive’s resignation effective immediately, or on such other date prior to the
Executive’s intended last day of work as the Company deems appropriate. Further, without altering the Executive’s status as an At-Will employee, the Company will endeavor to give the Executive two (2) weeks prior notice of termination
of employment if, under the circumstances, it is appropriate in the judgment of the Company to do so. 
 Section 4.2
Company’s Obligations upon Termination. Upon the termination of the Executive’s employment with the Company, whether with or without cause or notice and whether initiated by the Executive or the Company, the Executive shall, in full
discharge of all of the Company’s obligations to the Executive, be entitled to receive, and the Company’s sole obligation under this Agreement or otherwise shall be to pay or provide to the Executive, the following (collectively, the
“Accrued Obligations”): 
 (a) the Executive’s earned, but unpaid, Base Salary through the final date of
the Executive’s employment by the Company (the “Termination Date”), payable in accordance with the Company’s standard payroll practices; 
 (b) the Executive’s accrued, but unused, vacation (in accordance with the Company’s policies); 
 (c) expenses reimbursable under Section 3.2 above incurred on or prior to the Termination Date, but not yet reimbursed; and 

(d) any amounts or benefits that are vested amounts or vested benefits or that the Executive is otherwise entitled to receive under any

Section 4.3 Removal from any Boards and Position. If the Executive’s employment with the Company terminates for any
reason or no reason (whether initiated by the Company or the Executive), he shall be deemed (without further action, deed or notice) to resign (i) if a member, from the Board or board of directors (or similar governing body) of any Affiliate of
the Company or any other board to which he has been appointed or nominated by or on behalf of the Company and (ii) from all other positions with the Company or any subsidiary or other Affiliate of the Company, including, but not limited to, as
an officer of the Company and any of its subsidiaries or other Affiliates. 
 Section 4.4. Equity Vesting
Acceleration. 
 (a) In the event that, within twelve (12) months following a Change in Control (as defined below) of
the Company, the Company terminates the Executive’s employment hereunder without Cause (as defined below) (other than by reason of death or Disability (as defined below)) or the Executive resigns for Good Reason (as defined below), all stock
options and other awards that the Executive may have under the 2004 Plan and the 2013 Plan shall vest and, in the case of stock options or like awards, become exercisable, to the extent not already vested and (if applicable) exercisable, on the
Termination Date. 

  
 -5-









 (b) As used in this Agreement, “Change in Control” means (x) a change
in ownership of the Company under clause (i) below or (y) a change in the ownership of a substantial portion of the assets of the Company under clause (ii) below: 

(i) Change in the Ownership of the Company. A change in the ownership of the Company shall occur on the date that
any one person, or more than one person acting as a group (as defined in clause (iii) below), acquires ownership of capital stock of the Company that, together with capital stock held by such person or group, constitutes more than 50 percent of
the total fair market value or total voting power of the capital stock of the Company. However, if any one person or more than one person acting as a group, is considered to own more than 50 percent of the total fair market value or total voting
power of the capital stock of the Company, the acquisition of additional capital stock by the same person or persons shall not be considered to be a change in the ownership of the Company. An increase in the percentage of capital stock owned by any
one person, or persons acting as a group, as a result of a transaction in which the Company acquires capital stock in the Company in exchange for property will be treated as an acquisition of stock for purposes of this paragraph. 

(ii) Change in the Ownership of a Substantial Portion of the Company’s Assets. A change in the ownership of a
substantial portion of the Company’s assets shall occur on the date that any one person, or more than one person acting as a group (as defined in clause (iii) below), acquires (or has acquired during the 12-month period ending on the date
of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than 80 percent of the total gross fair market value of all of the assets of the Company immediately prior
to such acquisition or acquisitions. For this purpose, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets.
There is no Change in Control under this clause (ii) when there is a transfer to an entity that is controlled by the shareholders of the Company immediately after the transfer, as provided below in this clause (ii). A transfer of assets by the
Company is not treated as a change in the ownership of such assets if the assets are transferred to (a) a shareholder of the Company (immediately before the asset transfer) in exchange for or with respect to its capital stock, (b) an
entity, 50 percent or more of the total value or voting power of which is owned, directly or indirectly, by the Company, (c) a person, or more than one person acting as a group, that owns, directly or indirectly, 50 percent or more of the total
value or voting power of all the outstanding capital stock of the Company, or (d) an entity, at least 50 percent of the total value or voting power of which is owned, directly or indirectly, by a person described in clause (ii)(c) of this
paragraph. For purposes of this clause (ii), a person’s status is determined immediately after the transfer of the assets. 

  
 -6-









 (iii) Persons Acting as a Group. For purposes of clauses (i) and
(ii) above, persons will not be considered to be acting as a group solely because they purchase or own capital stock or purchase assets of the Company at the same time. However, persons will be considered to be acting as a group if they are
owners of a corporation that enters into a merger, consolidation, purchase or acquisition of assets or capital stock, or similar business transaction with the Company. If a person, including an entity, owns stock in both corporations that enter into
a merger, consolidation, purchase or acquisition of assets or capital stock, or similar transaction, such shareholder is considered to be acting as a group with other shareholders in a corporation only with respect to the ownership in that
corporation before the transaction giving rise to the change and not with respect to the ownership interest in the other corporation. For purposes of this paragraph, the term “corporation” shall have the meaning assigned such term under
Treasury Regulation section 1.280G-1, Q&A-45. 
 (iv) Each of clauses (i) through (iii) above shall
be construed and interpreted consistent with the requirements of Section 409A and any Treasury Regulations or other guidance issued thereunder. 
 (c) As used in this Agreement, “Cause” means: (i) a material act, or act of fraud, committed by the Executive that is intended to result in the Executive’s personal enrichment
to the detriment or at the expense of the Company or any of its Affiliates; (ii) the Executive is convicted of a felony; (iii) gross negligence or willful misconduct by the Executive, or failure by the Executive to perform the duties or
obligations reasonably assigned to the Executive by the Board or the CEO from time to time, which is not cured upon ten (10) days prior written notice (unless such negligence, misconduct or failure is not susceptible to cure, as determined in
the reasonable discretion of the Board); or (iv) the Executive violates the Covenants Agreement (as defined in Section 5.1 below) 
 (d) As used in this Agreement, “Disability” means a determination by the Company in accordance with applicable law that as a result of a physical or mental injury or illness, the
Executive is unable to perform the essential functions of his job with or without reasonable accommodation for a period of (i) ninety (90) consecutive days; or (ii) one hundred twenty (120) days during any twelve (12) month
period. 
 (e) As used in this Agreement, “Good Reason” means the occurrence of any of the following:
(1) a material breach by the Company of the terms of this Agreement; (2) a material reduction in the Executive’s Base Salary; (3) a material diminution in the Executive’s authority, duties or responsibilities; or
(4) the Company requires that Executive’s principal place of business for the performance of his duties under this Agreement be located outside of a 50 mile radius of Naples, Florida; provided, however, that the Executive
must notify the Company within ninety (90) days of the occurrence of any of the foregoing conditions that he considers it to be a “Good Reason” condition and provide the Company with at least thirty (30) days in which to cure the
condition. If the Executive fails to provide this notice and cure period prior to his resignation, or resigns more than six (6) months after the initial existence of the condition, his resignation will not be deemed to be for “Good
Reason.”

 -9-









 Section 5.7. Waiver. Either party hereto may waive compliance by the other party
with any provision of this Agreement. The failure of a party to insist on strict adherence to any term of this Agreement on any occasion shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence
to that term or any other term of this Agreement. No waiver of any provision shall be construed as a waiver of any other provision. Any waiver must be in writing. 
 Section 5.8. Severability. If any one or more of the terms, provisions, covenants and restrictions of this Agreement shall be determined by a court of competent jurisdiction to be invalid,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated and the parties will attempt to agree upon a
valid and enforceable provision which shall be a reasonable substitute for such invalid and unenforceable provision in light of the tenor of this Agreement, and, upon so agreeing, shall incorporate such substitute provision in this Agreement. In
addition, if any one or more of the provisions contained in this Agreement shall for any reason be determined by a court of competent jurisdiction to be excessively broad as to duration, geographical scope, activity or subject, it shall be
construed, by limiting or reducing it, so as to be enforceable to the extent compatible with then applicable law. 

Section 5.9. Counterparts. This Agreement may be executed in any number of counterparts and each such duplicate counterpart
shall constitute an original, any one of which may be introduced in evidence or used for any other purpose without the production of its duplicate counterpart. Moreover, notwithstanding that any of the parties did not execute the same counterpart,
each counterpart shall be deemed for all purposes to be an original, and all such counterparts shall constitute one and the same instrument, binding on all of the parties hereto. 

Section 5.10. Advice of Counsel. Both parties hereto acknowledge that they have had the opportunity to seek and obtain the
advice of counsel before entering into this Agreement and have done so to the extent desired, and have fully read the Agreement and understand the meaning and import of all the terms hereof. 

Section 5.11. Assignment. This Agreement shall inure to the benefit of the Company and its successors and assigns (including,
without limitation, the purchaser of all or substantially all of its assets) and shall be binding upon the Company and its successors and assigns. This Agreement is personal to the Executive, and the Executive shall not assign or delegate his rights
or duties under this Agreement, and any such assignment or delegation shall be null and void. 
 Section 5.12. Agreement
to Take Actions. Each party to this Agreement shall execute and deliver such documents, certificates, agreements and other instruments, and shall take all other actions, as may be reasonably necessary or desirable in order to perform his or its
obligations under this Agreement. 
 Section 5.13. No Attachment. Except as required by law, no right to receive
payments under this Agreement shall be subject to anticipation, commutation, alienation, sale, assignment, encumbrance, charge, pledge, or hypothecation or to execution, attachment, levy or similar process or assignment by operation of law, and any
attempt, voluntary or involuntary, to effect 

  
 -10-









 
any such action shall be null, void and of no effect; provided, however, that nothing in this Section 5.13 shall preclude the assumption of such rights by executors,
administrators or other legal representatives of the Executive or the Executive’s estate and their assigning any rights hereunder to the person or persons entitled thereto. 

Section 5.14. Source of Payment. Except as otherwise provided under the terms of any applicable employee benefit plan, all
payments provided for under this Agreement shall be paid in cash from the general funds of Company. The Company shall not be required to establish a special or separate fund or other segregation of assets to assure such payments, and, if the Company
shall make any investments to aid it in meeting its obligations hereunder, the Executive shall have no right, title or interest whatever in or to any such investments except as may otherwise be expressly provided in a separate written instrument
relating to such investments. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship, between Company and the Executive or any
other person. To the extent that any person acquires a right to receive payments from Company hereunder, such right, without prejudice to rights which employees may have, shall be no greater than the right of an unsecured creditor of Company. The
Executive shall not look to the owners of the Company for the satisfaction of any obligations of the Company under this Agreement. 
 Section 5.15. Tax Withholding. The Company or other payor is authorized to withhold from any benefit provided or payment due hereunder, the amount of withholding taxes due any federal, state
or local authority in respect of such benefit or payment and to take such other action as may be necessary in the opinion of the Board to satisfy all obligations for the payment of such withholding taxes. The Executive will be solely responsible for
all taxes assessed against him with respect to the compensation and benefits described in this Agreement, other than typical employer-paid taxes such as FICA, and the Company makes no representations as to the tax treatment of such compensation and
benefits. 
 Section 5.16. 409A Compliance. All payments under this Agreement are intended to comply with or be
exempt from the requirements of Section 409A of the Code and regulations promulgated thereunder (“Section 409A”). As used in this Agreement, the “Code” means the Internal Revenue Code of 1986, as amended. To
the extent permitted under applicable regulations and/or other guidance of general applicability issued pursuant to Section 409A, the Company reserves the right to modify this Agreement to conform with any or all relevant provisions regarding
compensation and/or benefits so that such compensation and benefits are exempt from the provisions of 409A and/or otherwise comply with such provisions so as to avoid the tax consequences set forth in Section 409A and to assure that no payment
or benefit shall be subject to an “additional tax” under Section 409A. To the extent that any provision in this Agreement is ambiguous as to its compliance with Section 409A, or to the extent any provision in this Agreement must
be modified to comply with Section 409A, such provision shall be read in such a manner so that no payment due to the Executive shall be subject to an “additional tax” within the meaning of Section 409A(a)(1)(B) of the Code. If
necessary to comply with the restriction in Section 409A(a)(2)(B) of the Code concerning payments to “specified employees,” any payment on account of the Executive’s separation from service that would otherwise be due hereunder
within six (6) months after such separation shall be delayed until the first business day of the seventh month following the Termination Date and the first 

  
 -11-









 
such payment shall include the cumulative amount of any payments (without interest) that would have been paid prior to such date if not for such restriction. Each payment in a series of payments
hereunder shall be deemed to be a separate payment for purposes of Section 409A. In no event may the Executive, directly or indirectly, designate the calendar year of payment. All reimbursements provided under this Agreement shall be made or
provided in accordance with the requirements of Section 409A, including, where applicable, the requirement that (i) any reimbursement is for expenses incurred during the Executive’s lifetime (or during a shorter period of time
specified in this Agreement), (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an eligible expense
will be made on or before the last day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement is not subject to liquidation or exchange for another benefit. In no event whatsoever shall the
Company be liable for any additional tax, interest or penalty that may be imposed on the Executive by Section 409A or damages for failing to comply with Section 409A. 

Section 5.17. 280G Modified Cutback. 
 (a) If any payment, benefit or distribution of any type to or for the benefit of the Executive, whether paid or payable, provided or to be provided, or distributed or distributable pursuant to the terms
of this Agreement or otherwise (collectively, the “Parachute Payments”) would subject the Executive to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the Parachute Payments shall be
reduced so that the maximum amount of the Parachute Payments (after reduction) shall be one dollar ($1.00) less than the amount which would cause the Parachute Payments to be subject to the Excise Tax; provided that the Parachute Payments shall only
be reduced to the extent the after-tax value of amounts received by the Executive after application of the above reduction would exceed the after-tax value of the amounts received without application of such reduction. For this purpose, the
after-tax value of an amount shall be determined taking into account all federal, state, and local income, employment and excise taxes applicable to such amount. Unless the Executive shall have given prior written notice to the Company to effectuate
a reduction in the Parachute Payments if such a reduction is required, which notice shall be consistent with the requirements of Section 409A to avoid the imputation of any tax, penalty or interest thereunder, then the Company shall reduce or
eliminate the Parachute Payments by first reducing or eliminating accelerated vesting of stock options or similar awards, then reducing or eliminating any cash payments (with the payments to be made furthest in the future being reduced first), then
by reducing or eliminating any other remaining Parachute Payments; provided, that no such reduction or elimination shall apply to any non-qualified deferred compensation amounts (within the meaning of Section 409A) to the extent such reduction
or elimination would accelerate or defer the timing of such payment in manner that does not comply with Section 409A. 

(b) An initial determination as to whether (x) any of the Parachute Payments received by the Executive in connection with the
occurrence of a change in the ownership or control of the Company or in the ownership of a substantial portion of the assets of the Company shall be subject to the Excise Tax, and (y) the amount of any reduction, if any, that may be required
pursuant to the previous paragraph, shall be made by an independent accounting firm selected by the Company (the “Accounting Firm”) prior to the consummation of such change in the ownership or effective control of the Company or in
the ownership of a substantial portion of the

assets of the Company. The Executive shall be furnished with notice of all determinations made as to the Excise Tax payable with respect to the Executive’s Parachute Payments, together with
the related calculations of the Accounting Firm, promptly after such determinations and calculations have been received by the Company. 
 (c) For purposes of this Section 5.17, (i) no portion of the Parachute Payments the receipt or enjoyment of which the Executive shall have effectively waived in writing prior to the date
of payment of the Parachute Payments shall be taken into account; (ii) no portion of the Parachute Payments shall be taken into account which in the opinion of the Accounting Firm does not constitute a “parachute payment” within the
meaning of Section 280G(b)(2) of the Code; (iii) the Parachute Payments shall be reduced only to the extent necessary so that the Parachute Payments (other than those referred to in the immediately preceding clause (i) or (ii)) 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 auditor or tax counsel
referred to in such clause (ii); and (iv) the value of any non-cash benefit or any deferred payment or benefit included in the Parachute Payments shall be determined by the Company’s independent auditors based on Sections 280G and 4999 of
the Code and the regulations for applying those sections of the Code, or on substantial authority within the meaning of Section 6662 of the Code.
