EXHIBIT 10d February 24, 2000 By Hand Delivery Admiral Huntington Hardisty 45 Bloomfield Ave. Hartford, CT 06105 Dear Hunt: This letter is to summarize our agreement regarding your decision to discontinue management responsibilities at Kaman Aerospace International. We are all very grateful that you are regaining your health and look forward to the continuing relationship between us, as described below. 1. Separation Payment. We have agreed that you will end your employment with Kaman Aerospace International Corporation on March 1, 2000 and your signature to this letter will constitute your resignation of your officer and director positions at that subsidiary. On that date, Kaman will make a lump sum payment to you in the amount of Three Hundred Seventy Thousand Dollars ($370,000). This payment will be subject to tax and any applicable employee benefit withholdings. 2. Restricted Stock Awards. As of March 1, 2000, you will have a total of Ten Thousand Six Hundred (10,600) Class A shares remaining subject to restriction pursuant to all of your restricted stock awards. As of that date, we will cause the restrictions to lapse and will deliver the share certificates to you. These shares will be valued at March 1, based on the closing price of the stock on that date, and the total value will be added to your taxable income for 2000. 3. Consultant's Agreement. Effective March 2, 2000, Kaman Aerospace Corporation will retain you as a consultant for a term of two (2) years at a per diem rate of One Thousand Dollars ($1,000) for each day that services are provided under the agreement. You will be guaranteed payment for a minimum of one hundred (100) days per year during the term of the agreement. This arrangement will be memorialized in a mutually satisfactory agreement that Kaman Aerospace will prepare. 4. Board of Directors, Kaman Corporation. We appreciate that you have agreed to continue serving as a member of the Board of Directors of the Corporation, subject of course to necessary shareholder approvals. Page 1 5. Employee Benefit Matters. We will be in contact with you regarding any other matters that are customarily associated with separation from employment, including confirmation of your account balance under the Corporation's Deferred Compensation Plan (in your case, the supplemental deferred compensation contributions that have been made by the Corporation) and information regarding the form of distribution that you have already chosen. If the foregoing accurately reflects your understanding of our agreement, please sign and date this letter in the space provided. When fully signed, this letter will constitute our entire agreement regarding this matter. As additional consideration for the payments described in paragraphs 1 and 2, this letter and your signature to the attached General Release and Agreement will also constitute your general release of Kaman from any matters other than those described here.
