Exhibit 10.2

FIRST AMENDMENT
TO THE COMPUTER SCIENCES CORPORATION SEVERANCE PLAN FOR SENIOR MANAGEMENT AND
KEY EMPLOYEES

This AMENDMENT to the Computer Sciences Corporation Severance Plan for Senior
Management and Key Employees (the “Plan”) is effective as of December 31, 2012.

W I T N E S S E T H:

WHEREAS, the board of directors of Computer Sciences Corporation (the “Company”)
has previously approved certain amendments to the Plan;

NOW, THEREFORE, the Plan is hereby amended as follows:

1.
Section 11 of the Plan is hereby amended in its entirety as follows:

11.    Effect Of Section 409A of the Code. Notwithstanding anything to the
contrary in this Plan, if, upon the advice of its counsel, CSC determines that
any payments or benefits to be provided to a Designated Employee who is a
“Specified Employee” (as such term is defined under Section 409A of the Code and
the regulations and other Treasury Department guidance promulgated thereunder
(collectively, “Section 409A”)) of an Employer (a “Specified Employee”) by CSC
or the Employer pursuant to Sections 5 or 6 of this Plan are or may become
subject to the additional tax under Section 409A(a)(1)(B) or any other taxes or
penalties imposed under Section 409A (“409A Taxes”) as applicable at the time
such payments and benefits are otherwise required under this Plan, then:

(a)    (i) such payments shall be delayed until the date that is the earlier of
six months after date of the Specified Employee’s “separation from service” (as
such term is defined under Section 409A) with the Company or the date of the
Specified Employee’s death, or such shorter period that, in the opinion of such
counsel, is sufficient to avoid the imposition of 409A Taxes (the “Payments
Delay Period”), and (ii) such payments shall be increased by an amount equal to
interest on such payments for the Payments Delay Period at a rate equal to the
default rate credited to amounts deferred under CSC’s Deferred Compensation
Plan, as amended; provided, however, that such rate shall be calculated on a
monthly average basis rather than a daily basis (the “Interest Rate”);

(b)    (i) with respect to the provision of such benefits, for a period of six
months following date of the Specified Employee’s “separation from service” (as
such term is defined under Section 409A) with the Company, or such shorter
period, that, in the opinion of such counsel, is sufficient to avoid the
imposition of 409A Taxes (the “Benefits Delay Period”), the Specified Employee
shall be responsible for the full cost of providing such benefits, and (ii) on
the first day following the Benefits Delay Period, the Employer shall reimburse
the Specified Employee for the costs of providing such benefits imposed on the
Specified Employee during the Benefits Delay Period, plus interest accrued at
the Interest Rate; and

(c)     the applicable Employer shall fund any payments to a Specified Employee
that are to be delayed as a result of the imposition of a Payment Delay Period
(including the interest to be paid with respect to such delayed payments) and/or
any payments that are expected to be paid to a Specified Employee as a result of
the imposition of a Benefits Delay Period

--------------------------------------------------------------------------------

(including any interest to be paid with respect thereto) (collectively, the
“Delayed Payments”) by establishing and irrevocably funding a trust for the
benefit of the applicable Specified Employee. Such trust shall be a grantor
trust described in Section 671 of the Code and intended not to cause tax to be
incurred by the Specified Employee until amounts are paid out from the trust to
the Specified Employee. The trust shall provide for distribution of amounts to
the Specified Employee in order to pay taxes, if any, that become due on the
amounts as to which payment is being delayed during the Payment Delay Period
pursuant to this Section 11, but only to the extent permissible under Section
409A of the Code without the imposition of 409A Taxes. The amount of such fund
shall equal a good faith estimate of the Delayed Payments determined by the
Company in consultation with the Specified Employee. The establishment and
funding of such trust shall not affect the obligation of the applicable Employer
to pay the Delayed Payments pursuant to this Section 11.

Specified Employees shall be identified as provided in CSC’s Specified Employee
Determination Policy, as amended.

2.
In all other respects, the Plan is hereby ratified and confirmed.

IN WITNESS WHEREOF, the Company has caused this Amendment to be adopted as of
the effective date indicated above.
