Sonnabend, Paul Sonnabend, and Stephen Sonnabend, effective as of January 1, 1992, and amended and updated in November 1995 (Paul) and March 1996 (Roger, Stephen), which replaced Restated Employment Agreements dated January 1, 1984, at annual base salaries of at least $418,374, $396,158, and $280,395, respectively. The current terms end December 31, 1999, but are automatically renewed for successive one year terms unless terminated by either party. Upon the death of any of such executives, the Company has undertaken to continue payments to their respective "Beneficiary" (as defined in the Agreement) in an amount equal to fifty percent (50%) of the applicable base salary as of the date of death, for a period of four years following death. Under separate agreements, dated December 31, 1991, and amended and updated in November 1995 (Paul) and March 1996 (Roger, Stephen), the Company has agreed that in the event of the permanent and total disability of Roger P. Sonnabend, Paul Sonnabend or Stephen Sonnabend while in the employ of the Company, the Company will continue payments to such executive in an amount equal to fifty percent (50%) of the applicable base salary at the date of disability, for a period of four years following the disability; and if death occurs during disability, for the balance of the four-year period, to the executive's spouse, estate or other designated beneficiary. Incentive Compensation Plan The Company has an incentive compensation plan under which pre-tax profit thresholds are established at the beginning of each year for certain of its hotels. Once the profit threshold is reached at a hotel, key employees of that hotel are entitled to receive a bonus equal to 3% of their annual salary, and 10% of any profits in excess of the threshold are shared proportionally by the same group. Additionally, key employees of each hotel may receive a bonus of up to two percentage points based on an evaluation of that hotel's performance in the areas of personal service and hotel physical appearance. The total incentive bonus paid out during each year is capped at 25% of base salary. Executive Office key employees, including officers of the Company, are entitled to receive incentive payments equal to that percentage of their respective salaries which equals the average (as a percentage of salaries) of all incentive payments made to certain hotel key employees as a group. Pension Plan The Company has an I.R.S. qualified defined benefit pension plan which covers all non-union salaried employees at its Executive Offices and its hotels in Boston (Cambridge), Key Biscayne and New Orleans. All officers and Directors who are full-time employees of the Company are covered under this plan. Benefits under the plan are based on the average compensation for the highest sixty consecutive months of service during employment, reduced proportionately for each year of service less than twenty-seven (full service period). The plan provides for integration with 50% of the primary Social Security benefit, reduced proportionately for each year of service less than twenty-seven. It provides for a normal retirement age of 65 and an early retirement age of 55 with five years of service. Benefits become vested at normal retirement age or upon the completion of five years of service and attaining the age of 21. Thus, the Company is unable to ascertain the benefits which may accrue to its Directors and/or officers since the benefits are based on variable factors. The following table sets forth a range of estimated annual retirement benefits under the plan upon retirement at age 65. 12 PENSION PLAN TABLE Average Annual Compensation for Years of Service Highest Sixty ------------------------------------------------------ Consecutive Months 15 20 25 30* 35* - ----------------------- ---------- ---------- ---------- ---------- ---------- $125,000 ................ $30,249 $40,332 $50,415 $54,448 $54,448 $150,000 ................ $37,193 $49,591 $61,989 $66,948 $66,948 $175,000 ................ $44,138 $58,850 $73,563 $79,448 $79,448 $200,000 ................ $51,082 $68,110 $85,137 $91,948 $91,948 $225,000 ................ $58,027 $77,369 $96,711 $104,448 $104,448 $250,000 ................ $64,971 $86,628 $108,285 $116,948 $116,948 $300,000 ................ $78,860 $105,147 $130,000 $130,000 $130,000 $350,000 ................ $92,749 $123,665 $130,000 $130,000 $130,000 $400,000 ................ $106,638 $130,000 $130,000 $130,000 $130,000 $450,000 ................ $120,527 $130,000 $130,000 $130,000 $130,000 $500,000 ................ $130,000 $130,000 $130,000 $130,000 $130,000 - -------- *The maximum benefit under the Company's Pension Plan is based on 27 years of service. The above benefits are calculated on a straight-life annuity basis and after deducting a portion of Social Security benefits, as described above. For 1998 the maximum benefit allowable under the Employee Retirement Income Security Act of 1974 is $130,000. Each of Roger, Paul and Stephen Sonnabend has the maximum number of years of credited service under the pension plan (27 years). Of the other individuals named in the Summary Compensation Table on page 11, Hans Wandfluh has 26 years of credited service, and Jacqueline, Peter and Stephanie Sonnabend have 15, 12 and 20 years of accredited service, respectively. Compensation Committee Report on Executive Compensation The compensation paid to Company executives has, for many years, consisted largely of two components: base salary and cash incentive bonus program. The Compensation Committee, which is comprised solely of non-management directors, is responsible for reviewing, approving and administering executive compensation. In evaluating executive compensation, the Committee considers several factors, including job responsibilities, job performance, the compensation paid to executives holding similar positions in other companies of comparable size and complexity to the Company, the performance and financial condition of the Company, factors unique to the Company, and changes in the cost of living. 13 The Compensation Committee met in January 1998 to consider the base salaries to be paid to the chief executive officer and the executives named in the Summary Compensation Table for 1998. The Committee noted the record performance in 1997 of the Company's hotels in Boston (Cambridge), Massachusetts, its leased hotel in New Orleans, Louisiana, and the improved results and enhanced facilities of its resort hotel in Anguilla, B.W.I. The year 1997 was also notable in that the Company completed the extensive renovation of one half of the guestrooms at its Boston hotel, and installed other improvements at the property including a new communications system; opened a new hotel in Luxor, Egypt; and entered into agreements for a new hotel in Miami Beach, Florida. Based on the above-mentioned factors, the Committee, on Management's recommendation, approved base salary increases for all executive officers of the Company, except the chief executive officer, the chairman of the executive committee and senior vice president, who for the third consecutive year received no increase in base salary. The increase in base salary for Hans U. Wandflluh was 8%, and the increase for Jacqueline, Peter and Stephanie Sonnabend was 20%. The second component of executive compensation relates to annual bonuses which may be earned by the chief executive officer as well as all other executive and key officers of the Company under the Company's Incentive Compensation Plan. The chief executive officer and the other named executive officers earn bonuses under this plan based on the average (as a percentage of salaries) of all incentive payments made to certain key hotel employees under the plan based on performance objectives established by Management and approved by the Compensation Committee at the beginning of each year for certain of the company's hotels. The Company's Incentive Compensation Plan is described in more detail under "Incentive Compensation Plan" contained elsewhere in this Proxy Statement. The Company has not maintained a stock option plan for several years and none of the executive officers named in the Summary Compensation Table presently holds any stock options. Stock options have not been deemed a necessary part of the Company's compensation program due in part to the fact that six of the seven named executive officers are beneficial owners of a significant number of shares of the Company's capital stock. Submitted by the Compensation Committee. Vernon R. Alden, Joseph L. Bower, Chairman, and Jean C. Tempel.
