(See p.12) ** Long Term Incentive Plan 11 Agreements with Executives The Company entered into Restated Employment Agreements with Roger P. 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, 1998, 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) 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 ................ $ 30,302 $ 40,403 $ 50,504 $ 54,544 $ 54,544 $150,000 ................ $ 37,247 $ 49,662 $ 62,078 $ 67,044 $ 67,044 $175,000 ................ $ 44,191 $ 58,922 $ 73,652 $ 79,544 $ 79,544 $200,000 ................ $ 51,136 $ 68,181 $ 85,226 $ 92,044 $ 92,044 $225,000 ................ $ 58,080 $ 77,440 $ 96,800 $104,544 $104,544 $250,000 ................ $ 65,025 $ 86,699 $108,374 $117,044 $117,044 $300,000 ................ $ 78,913 $105,218 $125,000 $125,000 $125,000 $350,000 ................ $ 92,802 $123,737 $125,000 $125,000 $125,000 $400,000 ................ $106,691 $125,000 $125,000 $125,000 $125,000 $450,000 ................ $120,580 $125,000 $125,000 $125,000 $125,000 $500,000................. $125,000 $125,000 $125,000 $125,000 $125,000 - -------- *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 1997 the maximum benefit allowable under the Employee Retirement Income Security Act of 1974 is $125,000. 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 25 years of credited service, and Jacqueline, Peter and Stephanie Sonnabend have 14, 11 and 19 years of accredited service, respectively. Compensation Committee Report on Executive Compensation The executive compensation program of the Company has, for many years, had two primary components: base salary and annual cash incentive compensation. These components are administered by the Compensation Committee of the Company which is comprised solely of non-management directors. The Committee evaluates executive compensation in light of numerous factors, including changes in the cost of living, job responsibilities, job performance, the compensation awarded to executives holding similar positions in other companies of comparable size and complexity to the Company, characteristics unique to the Company, and the performance and financial condition of the Company. Base salaries for the chief executive officer and the other executives named in the Summary Compensation Table for the year 1997 were determined by the Compensation Committee, which convened in early 1997 and 13 reviewed, in particular, the outstanding 1996 performances of the Company's owned hotel in Boston (Cambridge), Massachusetts and its leased hotel in New Orleans, Louisiana, as well as the improving results reported by the Company's resort hotel in Anguilla, B.W.I. The Committee also considered the Company's successful refinancing of the mortgage loan on Royal Sonesta Hotel Boston (Cambridge), and the amount of cash realized from the Company's sale of its interest in a building in New York City. Based on the foregoing and the factors set forth in the preceding paragraph, the Committee, on Management's recommendation, granted base salary increases to all executive officers of the Company, except the chief executive officer, the chairman of the executive committee and chief financial officer, and the senior vice president of the Company who received no increase in their base salaries for 1997. Generally, the average increase in base compensation for other executives of the Company was 4% for 1997. The second component of 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 such plan. The key hotel employees earn annual bonuses under the plan based upon 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 no longer maintains a stock option plan 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 the 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, Lawrence M. Levinson, and Jean C. Tempel.
