(collectively, the “Company”) together with the Company’s parent, sister companies, subsidiaries, divisions and affiliates, whether direct or indirect, its and their joint ventures and joint venturers (including their respective directors, officers, employees, shareholders, attorneys, partners and agents, past, present and future), and each of its and their respective successors and assigns (hereinafter collectively, the “Releasees”), from any and all known or unknown actions, causes of action, damages, claims or liabilities of any kind that have or could be asserted against any of the Releasees arising out of or related to my employment with and/or separation from employment with the Company or any of the other Releasees up to and including the date of this Waiver and Release Agreement, including, but not limited to:

3. Covenant Not To Sue. A “covenant not to sue” is a legal term which means I promise not to file a lawsuit in court.

2

any of the other Releasees from any reinstatement rights I have or could have. I acknowledge that I (i) have not suffered any on-the-job injury for which I have not already filed a claim, (ii) have received all compensation owed to me for hours worked, including overtime, if any, and (iii) have been provided all leave required by law or regulation.

I further understand that if I revoke this Waiver and Release Agreement, my employment with the Company will still be terminated and I will not receive the severance pay set forth in paragraph 2 of the Letter Agreement.

7. Unemployment. I understand that I am not waiving my right to file for unemployment insurance benefits.

8. Consideration. I also understand that the severance payments and benefits which I will receive in exchange for signing and not later revoking this Waiver and Release Agreement are in addition to anything of value to which I already am entitled.

3

10. Severability. I acknowledge and agree that if any provision of the Waiver and Release Agreement is found, held or deemed by a court of competent jurisdiction to be void, unlawful or unenforceable under any applicable statute or controlling law, the remainder of the Waiver and Release Agreement shall continue in full force and effect.
