NOW, THEREFORE, it is hereby agreed by and between the parties, for good and valuable consideration the receipt and sufficiency of which are hereby
acknowledged, as follows:

then current fiscal year assuming achievement under the Plan of the maximum performance targets for such fiscal year.

2. Benefits Upon
a Change of Control. If within twelve (12) months following a Change of Control (as defined below): (i) the Company shall terminate the Executives employment with the Company without Cause (as defined below), or (ii) the
Executive shall voluntarily terminate such employment with Good Reason (as defined below), the Company shall provide reimbursement of health care premiums for Executive and his dependents, for a period of eighteen (18) months from the date of

duties or actions consistent with the Executives then current position in a timely manner and otherwise in a manner reasonable acceptable to the Board and such failure or refusal shall have continued for a period of ten (10) days
following written notice from the Board describing such failure or refusal in reasonable detail;
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

l3d-3 promulgated under the Exchange Act) of fifty percent (50%) or more of the combined voting power of the Companys then-outstanding Voting Securities; provided, however, in determining whether or not a Change of Control has occurred,
Voting Securities which are acquired in a Non-Control Acquisition (as hereinafter defined) shall not constitute an acquisition which would constitute a Change of Control. A Non-Control Acquisition shall mean an acquisition by
(i) any employee benefit plan (or related trust) sponsored or maintained by the Company or any affiliate of the Company, (ii) the Company, (iii) any Person in connection with a Non-Control Transaction (as hereinafter defined), or

| | (ii) | individuals who, as of the date hereof, constitute the Board (the Incumbent Board) cease for any reason to constitute at least a majority of the Board; provided,
however, that any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Companys shareholders, was approved by a vote of at least a majority of the directors then comprising the
Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election
contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board; or

| | (iii) | the consummation of:

| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | no Person or Group, other than (i) the Company, (ii) any subsidiary of the Company, (iii) any employee benefit plan (or any trust forming a part thereof) maintained
by the Company immediately prior to such merger, consolidation, or reorganization, or (iv) any holder of the Companys Class A Common Stock as of the date hereof, owns twenty percent (20%) or more of the combined voting power of
the Surviving Corporations then-outstanding voting securities; or
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | --- | --------------------------------------------------------



| | (c) | the sale of disposition of all or substantially all of the assets of the Company to any Person.

Notwithstanding the foregoing, a Change of Control shall not be deemed to occur solely because any Person (the Subject Person) acquired
Beneficial Ownership of more than the permitted amount of the outstanding Voting Securities as a result of the acquisition of Voting Securities by the Company which, by reducing the number of Voting Securities outstanding, increases the proportional
number of shares Beneficially Owned by the Subject Person, provided that if a Change of Control would occur (but for the operation of this sentence) and after such acquisition of Voting Securities by the Company, the Subject Person becomes the
Beneficial Owner of any additional Voting Securities, then a Change of Control shall occur.

(d) Employment Termination shall
mean the effective date of: (i) Executives voluntary termination of employment with the Company with Good Reason, or (ii) the termination of Executives employment by the Company without Cause.

(e) Good Reason shall exist if, without Executives express written consent, the following occurs:

responsibilities, authority, powers or functions immediately prior to the Change of Control;

| | (ii) | if the Executive is no longer (a) an executive officer of a publicly-traded company, or (b) a Section 16 reporting person under the 1934 Act;
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | a reduction in the Executives Annual Salary; or
| | ----- | ------------------------------------------------

4. Certain Additional Payments by the Company. In the event it shall be determined at any time
that as a result, directly or indirectly, of any payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a
Payment), the Executive would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the Executive 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 the Executive shall be entitled to promptly receive from the Company an additional payment (a Gross-Up Payment) in an amount such that after
payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon
the Gross-Up Payment, but excluding any income taxes on the Payment, the Executive is in the same after-tax position as if no Excise Tax had been imposed upon the Executive. The Company shall pay the Gross-Up Payment to Executive no later than the
last day of Executives taxable year following the taxable year in which Executive remits the Excise Tax.

5. Mitigation and
Set-Off. Executive shall not be required to mitigate Executives damages by seeking other employment or otherwise, and except as expressly provided in Section 2 of this Agreement, the Companys obligations under this Agreement
shall not be reduced in any way by reason of any compensation or benefits received (or foregone) by Executive from sources other than the Company after Executives employment termination, or any amounts that might have been received by
Executive in other employment had Executive sought other employment.

6. Attorneys Fees. In the event that any suit or action
is instituted to enforce any provision in this Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to
this Agreement, including without limitation, such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals. Except as otherwise permitted by Section 409A, any
reimbursement to which Executive is entitled pursuant to this Section 6 shall (a) be paid no later than the last day of Executives taxable year following the taxable year in which the expense was incurred, (b) not be affected by
the amount of expenses eligible for reimbursement in any other taxable year, and (c) not be subject to liquidation or exchange for another benefit.

7. Assignment and Transfer. This Agreement shall not be terminated by the merger or consolidation of the Company with any corporate or other entity or by the transfer of all or substantially all of the assets
of the Company to any other person, corporation, firm or entity. In the event of a sale of all or substantially all of the assets of the Company and in connection with such sale the person or entity purchasing such assets does not assume this
Agreement, the Executive shall have the right to terminate his employment hereunder for Good Reason. The provisions of this Agreement shall be binding on and shall inure to the benefit of any such successor in interest to the Company. Neither this
Agreement nor any of the rights, duties or obligations of the Executive shall be assignable by the Executive, nor shall any of the payments required or permitted to be made to the Executive by this Agreement be encumbered, transferred or in any way
anticipated, except as required by applicable laws.

8. Severable Provisions. The provisions of this Agreement are severable and the
invalidity of any one or more provisions shall not affect the validity of any other provision.

9. Withholding. The Company may
withhold from any payment that it is required to make under this Agreement amounts sufficient to satisfy applicable withholding requirements under any federal, state or local law.

terms, as the Company shall determine, to make payments to Executive in accordance with the terms of this Agreement.
