A termination for “Cause” shall be effective immediately (or on such other date set forth by the Company).

5.2 By the Company Without Cause or Upon Expiration of the Term. If during the Term the Company terminates Executive’s employment without Cause (which may be done at any time without prior notice), or upon the expiration of the Term, the Executive shall receive the incremental severance payments set forth in this Section 5.2 (in addition to the payments upon termination specified in Section 5.1) upon execution without revocation of a valid release agreement in a form reasonably acceptable to the Company.
