remaining outstanding reimbursable expenses you have incurred through the

Non-Solicitation. You agree that the provisions of Section 9 of your Employment
Agreement (with the exception of Section 9.d. thereof), as modified by this
Agreement, concerning non-disclosure of Confidential Information, the return of
Greyhound property and the non-solicitation of Greyhound personnel, will
continue in effect. It is agreed that the non-competition provisions of Section
9.d. shall not apply. Unless otherwise agreed to in writing, you agree to return

Employment Agreement concerning indemnification in connection with your
employment with Greyhound through the Separation Date will continue in effect.
Additionally, the Indemnification Agreement dated October 16, 1998 by and
between you and Greyhound will remain in full force and effect.

6.       Other Commitments.

         Greyhound will reimburse you for all reimbursable business expenses, if
         any, incurred with the approval or at the request of Greyhound and will
         provide reasonable clerical support for any agreed upon transitional
         assistance you have agreed to provide. The non-disclosure obligations
         of your Employment Agreement will continue in effect during the course
         of any such transitional assistance.

         messages or mail in a timely manner.

         (d)      You, Greyhound and Parent have agreed that your separation of
         employment shall be communicated internally and externally as having
         resulted from the Parent's desire for a visible change at Greyhound and
         that none of us shall make any statement, oral or written, that is
         inconsistent with this understanding.

Agreement shall be in writing and sent or delivered in the manner prescribed by
