| | (b) | claims, actions, causes of action or liabilities arising under the Age Discrimination in Employment Act (ADEA) or under any other federal, state or local statute, law, ordinance or regulation regarding
discrimination on the basis of age; and/or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | claims, actions, causes of action or liabilities arising under any other federal, state, municipal or local statute, law, ordinance or regulation; and/or

| | (d) | any other claim whatsoever including, but not limited to, claims for severance pay or benefits (other than payments and benefits paid under the Letter Agreement), claims based upon breach of contract, promissory or

2.        Exclusions from General Release. Excluded from the General Release above are any
claims or rights which cannot be waived by law, including my rights to accrued vacation, if any. Specifically excluded from the General Release above are: (i) Mr. Delaneys Agreement of Indemnification with the Company dated
September 30, 2004 to the extent provided for by the terms of the Agreement; (ii) D&O coverage to the extent provided for by the terms of the applicable insurance policy; (iii) payments and benefits provided in the Letter

whether filed by me or another individual or entity.

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. It is different from the General Release of claims contained in paragraph 1 above. In addition to waiving and releasing the claims covered by that paragraph 1 above,
I further agree never to sue the Company and/or any of the other Releasees or become party to a lawsuit on the basis of any claim of any type whatsoever arising out of or related to my employment with and/or separation from employment with the
Company and/or any of the other Releasees. I agree not to become a member of any class in any case in which claims are asserted against the Company. I warrant and represent that I have not filed any complaint, claim or lawsuit against the Company
with any governmental agency or with any court. Notwithstanding this Covenant Not To Sue, I may bring a claim against the Company and/or any of the other Releasees to enforce this Agreement or to challenge the validity of this Waiver and Release
Agreement under the ADEA. I further acknowledge and agree in the event that I breach this paragraph, then (i) the Company shall be entitled to apply for and receive an injunction to restrain such violation of this paragraph, (ii) I shall
be obligated to pay the Company its costs and expenses incurred in enforcing this paragraph and defending against such lawsuit (including court costs, expenses and reasonable legal fees), and (iii) as an alternative to (ii), at the
Companys option, I shall be obligated upon demand to repay to the Company all but $250 of any severance payment paid to me under paragraph 2 of the Letter Agreement. I further agree that this Covenant Not to Sue will not affect the validity of
the Letter Agreement and will not be deemed to be a penalty or a forfeiture.
