Restricted Stock. The Director shall receive an annual issuance of one million (1,000,000) shares of the Company’s common stock, pursuant and subject to the Company’s Equity Incentive Plan. Such shares shall vest in four (4) equal amounts over a period of twelve (12) months, the initial amount vesting on September 14, 2018 of the Effective Date. Notwithstanding the foregoing, if the Director ceases to be a member of Board at any time during the vesting period for any reason (such as resignation, withdrawal, death, disability or any other reason), then any unvested shares shall be irrefutably forfeited.

The Corporation, as of the Effective Date, hereby grants to the Participant a Restricted Stock award of ​ shares of common stock, par value $0.10 per share, of the Corporation (the "Common Stock"), subject to the terms and conditions set forth herein and subject to the terms and conditions of the Plan which is incorporated herein by reference and made a part hereof for all purposes.

Restricted Stock. The Director shall be granted five hundred thousand (500,000) shares of restricted stock, to be granted promptly after the execution of this Agreement pursuant to the Restricted Stock Award Agreement in the form annexed hereto as [Appendix A]. In addition, the Director shall be granted shares of restricted stock in an amount equal to 0.25% of the fully diluted share count (including any and all outstanding common stock plus convertible securities, including convertible preferred shares, convertible debentures, granted stock options both vested and unvested, and warrants), following each annual stockholders meeting if re-elected as a Director of the Board by the stockholders of the Company (the “Re-Election Award”), the first grant of which will be made if re-elected at the first annual stockholders meeting that occurs at least 12 months after the Effective Date.

Provided that the Executive remains employed with the Company on the day following the expiration of the six months Probationary Period as set forth in Section 1 hereof, the Company shall grant to the Executive 50,000 Restricted Shares of the Company’s common stock under the Plan, pursuant to the terms and conditions of the Plan. The vesting of the Restricted Shares shall vest, subject to continued employment with the Company on the applicable vesting date, as follows: 15,000 immediately vested shares, 15,000 of the shares shall vest on the second anniversary of the Employment Commencement Date and the remainder shall vest on the third anniversary of the Employment Commencement Date.

Restricted Stock. A lump sum amount equal to the sum of # with respect to restricted shares and/or restricted share units granted to the Participant under any of the Equity Plans that were outstanding but not vested on the Relevant Date where such vesting of restricted shares and/or restricted share units was not determined by the attainment of performance goals, and which are forfeited as a result of the Participant's Separation from Service, an amount equal to the Fair Market Value of an equivalent number of shares of common stock of the Corporation (or such other equity security into which the restricted shares and/or restricted share units has been converted) on the date of Separation from Service, and # with respect to restricted shares and/or restricted share units granted to the Participant under any of the Equity Plans that were outstanding but not vested on the Relevant Date where such vesting of restricted shares and/or restricted share units was determined by the attainment of performance goals, and which are forfeited as a result of the Participant's Separation from Service, an amount equal to the Average PRSU Payout multiplied by the Fair Market Value of an equivalent number of shares of common stock of the Corporation (or such other equity security into which the restricted shares and/or restricted share units has been converted) based on the number of PRSU grants which are forfeited due to the Qualified Termination of Employment. The Participant will also be paid an amount equal to the equivalent of the amount of any dividends and other distributions which would have been paid on the number of shares of common stock of the Corporation (or such other equity security into which the restricted shares and/or restricted share units has been converted) determined based on the Average PRSU Payout determined under this section. The forfeited restricted shares and/or restricted share units determined by the attainment of performance goals according to a schedule determined by the Committee will not be paid. For purposes of this subsection # the Average PRSU Payout shall mean the three year average of the target percentage paid with respect to the restricted shares and/or restricted share units determined by the attainment of performance goals (the “PRSU’s”) awards paid to the Participant under the Equity Plans, or any successor or additional plan. The three year average of the PRSU’s paid to the Participant will be determined based on the higher of two target percentage averages computed during alternative three year periods consisting of either # the year in which the Relevant Date occurred (or, if the award is not yet paid as of the Relevant Date, for the preceding year) and the two preceding years or, # the year of the Qualified Termination of Employment (or, if the award is not yet paid as of the Qualified Termination of Employment, for the preceding year) and the two preceding years. If a Participant has been paid less than three years of PRSU’s the three year average of the PRSU’s paid to the Participant will be determined based on the average target percentage of the PRSU’s paid in prior years to the Participant under the Equity Plans, or any successor or additional plan. If a Participant has not received any prior payment of PRSU’s, the Average PRSU Payout under the Equity Plans, or any successor or additional plan, will be determined as follows:

Restricted Stock Awards/Restricted Stock Units. Employee’s unvested Restricted Stock Awards (“RSAs”) and Restricted Stock Units (“RSUs”) under the Company’s Amended and Restated Equity Incentive Plan and the Company’s 2015 Omnibus Incentive Plan (collectively, the “Equity Incentive Plans”) shall continue to vest through the Separation Date. Pursuant to the terms of the Employee’s Restricted Stock Award Agreements and Restricted Stock Unit Award Agreements, Employee agrees that any RSAs and RSUs that have not vested on or prior to the Separation Date are forfeited and cancelled. For avoidance of doubt, Employee shall not receive any additional RSAs or RSUs.

Restricted Stock and Restricted Stock Units. Any shares of Restricted Stock or Restricted Stock Units held by the Participant that have not vested, or with respect to which all applicable restrictions and conditions have not lapsed, shall immediately be deemed forfeited.
