WHEREAS, the Employee has been employed by the Company in various capacities, most recently as its Chief Executive Officer;

WHEREAS, the Employee has as of the Effective Date resigned from the position of Chief Executive Officer and the parties have mutually agreed to continue the Employee’s employment by the Company as herein provided; and

WHEREAS, the Employee and the Company desire to enter into this Agreement to set forth the terms and conditions of the Employee’s continued employment by the Company.

NOW, THEREFORE, in consideration of the mutual covenants and promises herein contained, and intending to be legally bound hereby, the Company and the Employee hereby agree as follows:

1. Employment.

1.1 The Company hereby agrees to continue to employ the Employee, and the Employee hereby agrees to accept continued employment with the Company, in a non-executive capacity upon the terms and for the period set forth in this Agreement.

1.2 Unless sooner terminated in accordance with the terms of this Agreement, the Employee’s term of employment hereunder shall mean the period commencing on the Effective Date and ending five (5) years thereafter, on May 3, 2024 (the “ Transition Period ”).  The Employee acknowledges and agrees, subject to the terms and provisions of this Agreement, that the Employee’s employment with the Company during the Transition Period shall continue to be on an at-will basis and this Agreement shall not establish any term of employment for a fixed term.  

2. Duties .  During the Transition Period, the Employee shall serve in such positions as the Company’s Chief Executive Officer and/or Board of Directors (the “ Board ”) may determine from time to time. The Employee shall provide such services as are consistent with his position.

3. Compensation and Related Matters.  

3.1 Base Salary .  During the Transition Period, the Employee shall receive an annualized base salary equal to $250,000, less applicable withholdings (the “ Base Salary ”), which shall be paid in accordance with the Company’s standard payroll practice.

3.2 Bonus Opportunities . During the Transition Period, the Employee shall no longer be entitled to receive any annual or long-term bonus awards or opportunities. The Company has previously awarded to the Employee the annual cash incentive compensation opportunity (the “ Annual Cash Incentive Award ”) and the long-term cash incentive compensation opportunities (the “ LT Cash Incentive Awards ”) set forth on Schedule A that remain outstanding as of the Effective Date.  

(a) Annual Cash Incentive Award .  Subject to the terms of this Agreement, the Employee is eligible to receive a prorated award payment for the Annual Cash Incentive Award, paid at the same time that payments under similar annual cash incentive awards are made by the Company, but not later than two and one-half (2½) months after the end of the calendar year in which the Annual Cash Incentive Award was earned by the Employee, assuming the Employee is still

employed by the Company at that time .  Proration will be based on the number of full months prior to the Effective Date (four (4)) divided by the number of months in the performance period (twelve (12)).  The Annual Cash Incentive Award will be paid only to the extent the applicable performance period objectives are met, as determined in accordance with the Cash Incentive Compensation Plan (the “ CICP ” ) (i.e., a payout is not guaranteed), provided that any applicable individual performance goals shall be deemed to have been 100% satisfied.  

(b) LT Cash Incentive Awards .  Subject to the terms of this Agreement, the Employee is eligible to receive the full amount of the award payment for each of the performance periods covered by the respective LT Cash Incentive Awards listed on Schedule A , paid at the same time that payments under similar long-term cash incentive awards are made by the Company, but not later than two and one-half (2½) months after the end of the respective performance period in which the LT Cash Incentive Award was earned by the Employee, assuming the Employee is still employed by the Company at that time.  Each LT Cash Incentive Award will be paid only to the extent the applicable performance period objectives are met, as determined in accordance with the CICP (i.e., a payout is not guaranteed), provided that any individual performance goals shall be deemed to have been 100% satisfied.

3.3 Equity-Based Awards .  During the Transition Period, the Employee shall no longer be entitled to receive any new equity awards.  The Company has previously granted to the Employee the equity awards (the “ Outstanding Equity Awards ”) as set forth on Schedule B that remain outstanding as of the Effective Date. Unvested stock options included within the Outstanding Equity Awards will continue to vest during the Transition Period pursuant to the vesting schedule set forth in the applicable award agreement.  Unvested restricted stock, restricted stock units and stock appreciation rights included within the Outstanding Equity Awards will continue to vest, and the restrictions on such restricted stock awards and restricted stock units will continue to lapse, during the Transition Period pursuant to the vesting schedule set forth in the applicable award agreement.  

3.4 Employee Benefits .  During the Transition Period and subject to the provisions of any applicable plan (including any insurance plan or program), the Employee and/or the Employee’s eligible dependents, as the case may be, shall be eligible to participate in and shall receive all coverage under welfare benefit plans practices, policies and programs provided by the Company (including, without limitation, medical, prescription, dental, disability, employee life, group life, and accidental death insurance plans and programs and the Company’s 401(k) plan, including Company-matching contributions, and deferred compensation plan), to the extent generally available to the executive officers of the Company.  Pursuant to Section 1 , Employee shall be considered a full-time employee of the Company during the Transition Period.

11

12.4 Notices .  All notices required hereunder shall be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed to the Employee, at the address maintained in the Company’s records, and to the Company as follows:

12.6 Injunctive Relief .  In recognition of the fact that a breach by the Employee of any of the provisions of Sections 6 or 7 or the continuing obligations as provided in Section 8 will cause irreparable damage to the Company and/or its affiliated companies, for which monetary damages alone will not constitute an adequate remedy, the Company shall be entitled as a matter of right (without being required to prove damages or furnish any bond or other security) to obtain a restraining order, an injunction, an order of specific performance, or other equitable or extraordinary relief from any court of competent jurisdiction restraining any further violation of such provisions by the Employee or requiring the Employee to perform the Employee’s obligations hereunder.  Such right to equitable or extraordinary relief shall not be exclusive but shall be in addition to all other rights and remedies to which the Company or any of its affiliated companies may be entitled at law or in equity, including without limitation the right to recover monetary damages for the breach of any of the provisions of this Agreement.

12.7 Taxes .  The Company may withhold from any amounts payable under this Agreement such Federal, state, local or foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation.  Notwithstanding any other provision of this Agreement, each party hereto agrees to be responsible for and to pay the taxes imposed on it by applicable law without any contribution from the other.

12.8 No Guarantee of Tax Consequences .  Notwithstanding anything in this Agreement to the contrary, the Company makes no representation, commitment or guarantee that any federal, state, local or other tax treatment will (or will not) apply or be available with respect to the payments and benefits provided under this Agreement (including whether or not the same are exempt from, or compliant with, Section 409A of the Code) and does not assume any responsibility or liability for all or any portion of any taxes, penalties, interest or other costs or expenses that may be incurred by the Employee (or any person claiming through or on behalf of the Employee) with respect thereto.
