Such payment shall be made in equal incremental payments, consistent with the Company's usual payroll payment periods, over a period of four (4) months immediately following your last day of employment with the Company. As used herein, the term "cause" means (i) your willful breach or gross neglect of the duties and obligations required of you either expressly or impliedly by the terms of this letter agreement; or (ii) your commission of fraud, embezzlement or misappropriation, involving the Company whether or not a criminal or civil charge is filed in connection with such activity.

In consideration of this letter agreement, you release and forever discharge Pro-Dex, and each of its respective employees, shareholders, officers, directors, agents, attorneys, or affiliated corporations or organizations, and Pro-Dex releases and forever discharges you from any and all claims, whether or not now known by you or by Pro-Dex, up to the date of this letter. Claims released by you hereunder include, but are not limited to, any claims relating to your compensation (including wage, salary, bonus, commission, incentive, vacation, medical insurance benefits, or other compensation); rights arising out of alleged violations of any contracts, express or implied; any covenant of good faith and fair dealing, express or implied; any tort; and, without limitation, any local, state, or federal statute, rule, regulation, ordinance, law, or constitutional provision, governing employment, employment termination, discrimination or harassment in employment, or the payment of wages or benefits, but do not include wages or benefits currently payable in the ordinary course of your employment as provided herein.

You and Pro-Dex each understand and agree that you and it are making a mutual general release of all claims, and that this release is intended to encompass all known and unknown, foreseen and unforeseen claims which you or any of your heirs, legal representatives, successors, or assigns may have against Pro-Dex or any other related person or entity, and all known and unknown, foreseen and unforeseen claims which Pro-Dex may have against you.

(General Release - Claims Extinguished.) A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor."
