(e) Life Insurance. CNT shall pay for Executive's life insurance coverage under COBRA through Reliance Standard Insurance Company's group policy for six months after the date of this Agreement.

Executive hereby confirms his obligations under the provisions of Sections 4 and 5 of his Employment Agreement with CNT dated May 10, 1994. Executive shall treat the terms and conditions of this Agreement as confidential information of CNT and shall not disclose such terms to any person, except to members of his immediate family, his attorneys and accountants, and such other persons to whom disclosure may be required by law. 6. Release. (a) Settlement. While Executive asserts that he has certain claims against CNT, Executive acknowledges that CNT denies any liability to Executive for any violation of any legal rights of Executive and Executive acknowledges that the amounts payable to him pursuant to this Agreement constitute a substantial benefit to Executive over and above the amount to which he would otherwise have been entitled under the terms of CNT's severance practice had he not entered into this Agreement. CNT and Executive intend by this Agreement to settle any and all claims Executive has or may have against CNT arising out of or relating to CNT's employment of Executive or the termination thereof. (b) Settlement Payments. CNT shall pay to Executive the gross amount of $26,250 as initial settlement payments, in six equal semi-monthly installments of $4,375.

If Executive is unemployed, the additional installments shall be $4,375 each. If Executive is 2 employed at a monthly gross compensation less than $8,750, these installments shall each be in an amount equal to the difference between (i) $4,375 minus (ii) one-half of Executive's new monthly gross compensation. To receive installments of additional settlement payments under this Section 6(b), Executive must notify CNT at least five and no more than ten days prior to payment of each installment that he is not employed or that he is employed at a monthly gross compensation of less than $8,750, as the case may be.
