Following your retirement on September 30, 1996, you will be entitled to the compensation and benefits set forth below in accordance with and subject to the following terms: A. You will receive severance pay, equal to $493,553 (a total of 65.155 weeks' severance pay) paid in the form of a lump sum in October 1996. B. Incentive Compensation You will be considered for a prorated annual incentive compensation award for 1996 based on the financial performance of the Company and your individual performance. Your 1996 award, which is subject to Board approval, will be paid to you in March 1997. C. Executive Salary Protection Plan and Split-Dollar Life Insurance Plan Your death benefit coverage under the Executive Salary Protection Plan shall cease on October 31, 1996, while your disability coverage under that Plan will cease on September 30, 1996, in accordance with the terms of that Plan. Your participation in the Split-Dollar Life Insurance Plan will cease on November 30, 1996, although you may purchase the policy by reimbursing the Company for the premiums paid by the Company for that policy on your behalf through the date of your retirement. Estimated premiums paid by the Company through November 30, 1996 are expected to total approximately $323,000 for five policy years with estimated cash value of approximately $270,000. Your death benefit coverage is $1,000,000 under the split dollar policy and $560,000 under the Company-paid group basic life plan. D. Long-Term Incentive Plan Your participation in the Company's Long-Term Incentive Plan for the 1994-96, 1995-97 and 1996 -98 Performance Periods will vest and be paid to you at the same time as other 2 - 2 - participants. Your awards for 1994-96, 1995-97 and 1996-98 will be prorated as of your September 30, 1996 retirement date. E. Stock Options Your November 5, 1987, October 4, 1990, December 5, 1991, December 3, 1992, November 4, 1993, April 7, 1994 and March 2, 1995 stock option grants are fully vested. Subject to SEC requirements and restrictions (as to which you should consult Bob Lamm), you will be free to exercise your stock options and to sell the shares acquired on exercise following your resignation as an officer of the Company on September 30, 1996. After your retirement, you will have a three-year grace period during which you may exercise your options, except for the November 5, 1987 grant which will expire on its existing expiration date of November 4, 1997. F. Stock Swap Arrangement The 12,676 shares of restricted stock granted to you under the August 1, 1991 "Stock Swap Arrangement" are scheduled to have the restrictions lapse in five equal installments during the five-year period beginning January 31, 1997 and ending with the restrictions lapsing on the last installment on January 31, 2001. The 49,000 stock options you received under that arrangement are scheduled to vest in five equal annual installments beginning January 31, 1997 through January 31, 2001. Notwithstanding this schedule, as a result of your retirement on September 30, 1996, all such stock options will vest, to the extent not already vested, on March 31, 1999 (30 months following your retirement) and you will have until September 30, 1999 to exercise such options during the six month remainder of the three-year grace period following your retirement.
