                              CERIDIAN CORPORATION
                            EXECUTIVE INVESTMENT PLAN

                         SECOND DECLARATION OF AMENDMENT

Pursuant to the retained power of amendment contained in Section 6.2 of the
Ceridian Corporation Executive Investment Plan, the undersigned hereby amends
the Plan in the manner described below.

1.       Section 1.4 of the Plan is amended by adding a new Subsection (c) which
         reads as follows:

         (c)      In connection with the spin-off by Ceridian Corporation of all
                  of the outstanding common stock of New Ceridian Corporation
                  ("New Ceridian"), a Delaware corporation and wholly owned
                  subsidiary of Ceridian Corporation (the "New Ceridian
                  Spin-off"), the Plan was amended, effective as of March 27,
                  2001, to effect the transfer of sponsorship of the Plan from
                  Ceridian Corporation to New Ceridian Corporation. Following
                  the New Ceridian Spin-off, Ceridian Corporation was renamed
                  Arbitron Inc. and New Ceridian was renamed Ceridian
                  Corporation.

2.       Section 7.10 of the Plan is amended to read as follows:

         7.10     COMPANY.

                  "Company" means New Ceridian Corporation, renamed Ceridian
         Corporation after the New Ceridian Spin-off.

3.       Section 7.28 of the Plan is amended to read as follows:

         7.28.    QUALIFIED EMPLOYEE.

                  "Qualified Employee" means an individual who performs services
         for a Participating Employer as an employee of the Participating
         Employer (as classified by the Participating Employer at the time the
         services are performed without regard to any subsequent
         reclassification) and who is (a) an officer of the Participating
         Employer elected by the Participating Employer's Board, (b) a Vice
         President of the Participating Employer or (c) a Director of the
         Participating Employer with a salary grade level of D1 or D2.

The amendments set forth at items 1 and 2 above are effective as of March 27,
2001, and apply to all Participants, including Participants who terminated
employment prior to the effective date of the amendment. The amendment set forth
at item 3 above is effective immediately after the New Ceridian Spin-off, as
defined at item 1 above.
