1 EXHIBIT 10.1 January 19, 1998 Mr. Mark Tapling 4734 Lohr Road Ann Arbor, MI 48108 RE: LETTER OF UNDERSTANDING Dear Mark: This letter ("Agreement") confirms the terms and conditions of your termination from Comshare, Incorporated ("Comshare") under mutually agreed upon circumstances. The arrangement will be as follows: (1) Your termination from Comshare, Incorporated will be effective on February 9, 1998 ("Termination Date"). (2) Comshare agrees to pay you salary continuation pay commencing from your "Termination Date" until January 29, 1999 ("Salary Continuation Period"). After April 17, 1998, Comshare will apply all of your future salary continuation payments, less appropriate federal and state withholdings and deductions, to the outstanding balance of your stock loan. You agree to repay any outstanding balance of your stock loan, if your total obligation is not exhausted through salary continuation. If your stock loan is repaid in full during the salary continuation period, payroll deductions for loan repayment will cease. You will be paid $7,692.31 bi-weekly during the Salary Continuation Period, less appropriate federal and state withholdings and deductions, on Comshare's regular, scheduled pay dates. Your group health, dental, vision, and life coverage, including elected dependent coverage, which are currently in effect shall continue for you and any of your covered dependents for six (6) months (July 17, 1998) or you secure other employment, whichever occurs first, provided that Comshare shall have the right to change such coverage to the extent Comshare is generally changing coverage for its employees. You shall continue to make required contributions, via payroll deductions, at the then current rate for similarly situated Comshare employees. Long-term disability coverage ceases on your Termination Date (February 9, 1998). There is no conversion option available for this benefit. (3) In addition, we will pay your bi-weekly car allowance of $436.15 through April 30, 1998. (4) You will be provided with reasonable tax return preparation provided by Arthur Andersen for calendar year, 1997. (5) You will be eligible to participate in an executive outplacement program conducted by a firm that is selected by you and Comshare. The costs of the program will be borne by Comshare and will not exceed $10,000. You may also retain your current voice mail box until September 30, 1998. (6) Comshare shall make available to you and your qualified dependents, the election of coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") at the time required by COBRA. (7) You will not accrue vacation benefits during the Salary Continuation Period. All unused and accrued vacation that is available to you, as of your Termination Date, will be paid within two weeks of February 9, 1998. Our records indicate that you have twenty (20) vacation days. (8) You will not be eligible to continue your participation in the Profit Sharing Plan, including the 401K option, throughout the Salary Continuation Period.
