WHEREAS, the Parties acknowledge that the Company’s sale of the services business is beneficial to both Parties and both Parties desire such sale to be concluded;

NOW, THEREFORE, as an inducement for and in consideration of the Employee’s continued employment, the mutual promises set forth in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the Employee hereby further agree as follows:

(b)    Stock Options and Restricted Stock Vesting.    Each outstanding option to purchase shares of Common Stock of the Company held by the Employee immediately prior to the Services Business Sale shall become immediately exercisable in full; and each outstanding restricted stock award held by the Employee shall be deemed to be fully vested and no longer subject to a right of repurchase by the Company.

(c)    Other Benefits.    To the extent not previously paid or provided, the Company shall timely pay or provide to the Employee any other amounts or benefits required to be paid or provided or which the Employee is eligible to receive following the Employee’s termination of employment under any plan, program, policy, practice, contract or agreement of the Company and its affiliated companies.

(d)    Additional Bonus.    If either (i) within six (6) months following the later of the Change in Control Date or the Employee’s first date of employment with Unisys, the Employee’s employment with Unisys is terminated by Unisys other than for Cause, or by reason of the Employee’s Death or Disability or (ii) the Employee remains employed for six (6) full months following the later of the Change in Control Date or the Employee’s first date of employment with Unisys, then the Company shall pay to the Employee in a lump sum within 30 days after the earlier to occur of the event set forth in clause (i) or clause (ii), the aggregate amount of $100,000.
