                  deemed at all times to be the Collateral Value of the
                  7,128,772 shares of Capital Stock of Computer Sciences
                  Corporation that are exchanged by the Guarantor for the
                  Capital Stock of Newco, as determined immediately prior to

                  (c) The definition of "Marketable Securities" in Section 1.01
         is hereby amended by adding a proviso at the end of such definition to

         time that the Capital Stock of Newco is required to be pledged to the
         Administrative Agent for the benefit of the Lenders, neither the
         Borrower nor the Guarantor shall permit Newco to (i) create, incur,
         assume or suffer to exist any Lien upon any of its property, assets or

material agreement or instrument to which any such Person is a party or by which
any of its properties may be bound or the approval of any Governmental Authority
relating to such Person except as could not reasonably be expected to have a
Material Adverse Effect, (e) the representations and warranties contained in

         5. No Other Changes; Ratification. Except as expressly modified hereby,
all of the terms and provisions of the Credit Agreement (including schedules and
exhibits thereto) and the other Loan Documents shall remain in full force and
effect. The term "this Agreement" or "Credit Agreement" and all similar
references as used in each of the Loan Documents shall hereafter mean the Credit
Agreement as amended by this Amendment. Except as herein specifically agreed,
the Credit Agreement is hereby ratified and confirmed and shall remain in full
force and effect according to its terms.

         6. Costs and Expenses. The Borrower agrees to pay all reasonable costs
and expenses of the Administrative Agent in connection with the preparation,
execution and delivery of this Amendment, including without limitation the
reasonable fees and expenses of Moore & Van Allen, PLLC.

         7. Counterparts; Facsimile. This Amendment may be executed in any
number of counterparts, each of which when so executed and delivered shall be
deemed an original and it shall not be necessary in making proof of this
Amendment to produce or account for more than one such counterpart. Delivery of
an executed counterpart of this Amendment by telecopy by any party hereto shall
be effective as such party's original executed counterpart.

         8. Governing Law. This Amendment shall be deemed to be a contract made
under, and for all purposes shall be construed in accordance with, the laws of
the State of New York.

         9. Entirety. This Amendment and the other Loan Documents embody the
entire agreement between the parties and supersede all prior agreements and
understandings, if any, relating to the subject matter hereof. These Loan
Documents represent the final agreement between the parties and may not be
contradicted by evidence of prior, contemporaneous or subsequent oral agreements
of the parties. There are no oral agreements between the parties.


         10. Acknowledgment of Guarantor. The Guarantor acknowledges and
consents to all of the terms and conditions of this Amendment and agree that
this Amendment and any documents executed in connection herewith do not operate
to reduce or discharge the Guarantor's obligations under the Credit Agreement or
the other Loan Documents.

         11. Affirmation of Liens. Each Loan Party affirms the liens and
security interests created and granted by it in the Loan Documents (including,
but not limited to, the Security Agreement) and agrees that this Amendment shall
in no manner adversely affect or impair such liens and security interests.

         12. Excluded Disposition. For the avoidance of doubt, the Lenders
hereby acknowledge and agree that, so long as the Acquisition of the Capital
Stock of Newco constitutes a Permitted Acquisition, the Disposition of the
Capital Stock of Computer Sciences Corporation constitutes a Permitted
Investment and, therefore, an Excluded Disposition under clause (v) of such
definition.
