WHEREAS, Analysis & Technology, Inc. (the "Employer") heretofore adopted the
Analysis & Technology, Inc. Savings and Investment Plan (the "Plan"); and

WHEREAS, the Employer reserved the right to amend the Plan; and

WHEREAS, the Employer desires to amend the Plan to reflect the merger of the
Applied Science Associates, Inc. Employee Stock Ownership and Profit Sharing
Plan into the Plan;

NOW, THEREFORE, the Plan is hereby amended, effective, except as otherwise
specifically provided, as of September 30, 1995, as follows:

1.   Section 2.1 of the Plan shall be amended to read in its entirety as 
     follows:

     2.1 YEAR OF SERVICE. An Employee shall be credited with a Year of Service
     for each Plan Year in which he is credited with at least one thousand
     (1,000) Hours of Service.

     Effective January 1, 1995, any Participant who was a participant in the
     Applied Science Associates, Inc. 401(k) Retirement Savings Plan (the "ASA
     401(k) Plan") and whose account balance under the ASA 401(k) Plan was
     transferred to this Plan in connection with the merger of the ASA 401(k)
     Plan with this Plan shall be credited with an additional Year of Service in
     determining such Participant's nonforfeitable (vested) right to his Account
     under the applicable vesting schedule pursuant to Section 6.1.

     For purposes of this Section 2.1, any Employee of Applied Science
     Associates, Inc. who becomes a Participant in this Plan on or after
     September 30, 1995 shall be credited with any "Years of Service" completed
     under the Applied Science Associates, Inc. Employee Stock Ownership and
     Profit Sharing Plan (the "ASA Profit-Sharing Plan"). In addition, any
     Participant who was a participant in the ASA Profit-Sharing Plan and whose
     account balance under the ASA Profit-Sharing Plan was transferred to this
     Plan in connection with the merger of the ASA Profit-Sharing Plan with this
     Plan shall be credited with an additional Year of Service in determining
     such Participant's nonforfeitable (vested) right to his Account under the
     applicable vesting schedule pursuant to Section 6.1.

2.   Article Eight of the Plan shall be amended by adding the following Section
     8.3:

     8.3 WITHDRAWAL OF ASA PLAN ACCOUNT. The provisions of this Section shall
     apply to any Participant who was a participant in the Applied Science
     Associates, Inc. Employee Stock Ownership and Profit Sharing Plan (the "ASA
     Plan") and whose account balance under the ASA Plan (the Participant's "ASA
     Account") was transferred to this Plan in connection with the merger of the
     ASA Plan with this Plan as of September 30, 1995. Any such Participant, who
     is 100% vested in his 

                                       1

     Account under Section 6.1, may apply in writing to the Plan Administrator
     to withdraw up to 50% of the balance of his ASA Account. However, such
     withdrawal may not exceed that part of the balance of the ASA Account
     attributable to contributions that had been credited to the Participant's
     ASA Account for at least five (5) years. Withdrawals shall be paid as soon
     as administratively practicable following such Participant's withdrawal
     request. However, once a Participant makes a withdrawal under this Section
     8.3, he may not make another such withdrawal until three (3) years after
     the date of the prior withdrawal.

3.   Except as hereinabove amended, the provisions of the Plan shall continue
     in full force and effect.

IN WITNESS WHEREOF, the Employer, by its duly authorized officer, has caused
this Amendment to be executed on the 9th day of September 1995.
