                         COMPUTER SCIENCES CORPORATION
                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN


                                 ARTICLE I

                                  Purpose
                                  -------

     The purpose of this Supplemental Executive Retirement Plan ("Supplemental 
Plan") is to provide retirement benefits to designated officers and key 
executives of Computer Sciences Corporation (the "Company") in addition to 
retirement benefits that may be payable under the Computer Sciences 
Corporation Employee Pension Plan, and in addition to any other retirement 
plan (other than the social security system to the extent provided herein) 
under which benefits may be payable with respect to such person.

     It is intended that this Supplemental Plan be a plan "for a select group 
of management or highly compensated employees" as set forth in Section 201(2) 
of the Employee Retirement Income Security Act of 1974.

     Benefits under this Supplemental Plan shall be payable solely from the 
general assets of the Company and no Participant or other person shall be 
entitled to look to any source for payment of such benefits other than the 
general assets of the Company.


                                  ARTICLE II

                       Effective Date/Restatement Date
                       -------------------------------

     The Supplemental Plan was effective as of September 1, 1985. It is hereby 
amended and restated effective November 4, 1996.


                                  ARTICLE III

                                  Participants
                                  ------------

     No person shall be a Participant in this Supplemental Plan unless (a) 
such individual is specifically designated as such in a written instrument 
executed by the Chief Executive Officer of the Company (the "Chief Executive 
Officer"), and (b) such individual has consented to be governed by the terms 
of this Supplemental Plan by execution of a written instrument in form 
satisfactory to the Company.

     A person shall cease to be a Participant in this Supplemental Plan in the 
event of (a) a Plan amendment having such effect, or (b) the occurrence of an 
event described in this Supplemental Plan which terminates such participation, 
or (c) the Chief Executive Officer notifies such person, in writing, of the 
discontinuance of 




such person's participation pursuant to Article XVIII of this Supplemental 
Plan. In determining whether any person shall commence or cease to be a 
Participant herein, the Chief Executive Officer, acting in such capacity, 
shall have complete and unfettered discretion.


                                   ARTICLE IV

                               Retirement Benefits
                               -------------------

     The amount of retirement benefit payable to each Participant upon 
Separation from Service (as defined in paragraph (d) below) shall be as 
determined in this Article IV.

     (a)  A Participant who is entitled to receive a benefit under the 
Computer Sciences Corporation Employee Pension Plan ("Pension Plan"), shall be 
entitled to receive his Excess Benefit under this Supplemental Plan upon being 
fully vested under the Pension Plan. The Excess Benefit is the additional 
monthly amount which the Participant would otherwise be entitled to receive 
under the Pension Plan as if the Participant had elected the normal form of 
life annuity payment option under the Pension Plan except for the limitations 
imposed by Sections 401(a)(17) and 415 of the Internal Revenue Code, as 
amended. In addition to the benefit described in this paragraph (a), a benefit 
as described in paragraph (b) following shall be payable to the Participant.

     (b)  Each Participant, upon Separation from Service on or after 
attainment of age sixty-two (62) (the "Retirement Date"), shall receive an 
amount as determined under this paragraph (b) which is payable monthly in the 
form of a life annuity. The amount payable shall be equal to one-twelfth 
(1/12) of fifty percent (50%) of the Participant's Average Base Salary Rate 
(as defined in paragraph (d) below) reduced by the amount determined under 
paragraph (c) below and, as applicable, paragraph (e) below.

     (c)  The amount determined under this paragraph (c) shall generally be 
equal to the primary social security benefit paid or payable to the 
Participant at the time benefits commence under this Supplemental Plan, 
whether or not the Participant is denied social security benefits because of 
other income or voluntarily forgoes social security income. However, where a 
Participant commences to receive benefits under this Supplemental Plan prior 
to the date that he is entitled to commence receiving social security benefits 
(currently age sixty-two (62)), his benefits under this Plan shall be reduced, 
by the amount of social security benefits it is estimated he would be entitled 
to receive monthly. The estimated social security benefit will be calculated 
based on the Participant's compensation through his Separation from Service 
date as though he were age sixty-two (62) on such date, and in accordance with 
social security rules in effect at the time of his Separation from Service.  
If the Participant has qualified for a special early separation benefit 
pursuant to paragraph (b) of Article V, then a five percent (5%) 


                                       2



annual reduction factor, with proportionate fractional reduction for periods 
of fewer than twelve (12) months, shall be applied to the estimated social 
security benefit for the period between the date of the Participant's 
Separation from Service and the date he is expected to attain age sixty-two 
(62). By way of example, if a Participant otherwise entitled to benefits 
commencing at age sixty-two (62) retires at age sixty (60) and qualifies for a 
special early separation benefit pursuant to paragraph (b) of Article V and 
the Participant's social security benefit is assumed to be $8,000 a year at 
the projected age of sixty-two (62), then the estimated annual social security 
benefit determined under this paragraph (c) will be $7,200, which is the 
$8,000 reduced at 5% per year for two years, or 10% .

     (d)  The term "Base Salary Rate" means the annual salary rate of a 
Participant exclusive of overtime, bonus, incentive or any other type of 
special compensation. The term "Average Base Salary Rate" means the average of 
the highest three (3) of the last five (5) Base Salary Rates of a Participant 
which are the Base Salary Rates in effect on his Retirement Date and on the 
same day and month for each of the four (4) years (or the period of Continuous 
Service if fewer than four (4) years) immediately preceding the Retirement 
Date.

     Unless otherwise determined in writing with respect to a Participant by 
the Chief Executive Officer, the term "Continuous Service" means the period of 
service without interruption of a person commencing as of the date of hire of 
such person by the Company or an Affiliate and ending on the date of 
separation from service for any reason from the Company and all Affiliates 
("Separation from Service"). The term "Affiliate" means a corporation or other 
entity of which fifty-one percent (51%) or more of the capital stock or 
capital or profits interest (in the case of a noncorporate entity) is directly 
or indirectly owned by the Company. A medical leave of absence not exceeding 
twelve (12) months authorized by a Company written policy or any other leave 
of absence authorized by a Company written policy or approved in writing by 
the Chief Executive Officer shall not be deemed an interruption in Continuous 
Service or a Separation from Service.

     In the event the Company acquires a corporation or other entity 
("Acquisition"), and any employee of the Acquisition, by written determination 
of the Chief Executive Officer of the Company, becomes a Participant in the 
Supplemental Plan, such Participant's period of Continuous Service shall 
commence no sooner than the date the Acquisition becomes an Affiliate of the 
Company unless the Company's Chief Executive Officer otherwise determines and 
so confirms in writing.

     (e)  If upon Separation from Service on or after attaining age sixty-two 
(62), or upon the granting of a special early separation benefit pursuant to 
paragraph (b) of Article V, a Participant has fewer than twelve (12) years of 
Continuous Service, the benefit otherwise payable under this Supplemental Plan 
shall be proportionately reduced, except for the benefit payable under 
paragraph (a) 


                                       3



of this Article IV which shall not be reduced. By way of example, if a 
Participant otherwise entitled to benefits hereunder commencing at age sixty-
two (62) has completed only ten (10) years of Continuous Service upon 
attainment of age sixty-two (62), such Participant's benefit shall be 10/12, 
or 83.33%, of the benefit otherwise payable hereunder.

     Unless expressly determined to the contrary in writing by the Chief 
Executive Officer, no period of service completed by a person after attainment 
of age sixty-five (65) and no adjustment to any person's Base Salary Rate 
which occurs after attainment of age sixty-five (65) shall be taken into 
account in computing benefits hereunder.


                                   ARTICLE V

                           Eligibility for Benefits
                           ------------------------

     (a)  Participants shall become eligible to commence receiving retirement 
benefits under this Supplemental Plan after Separation from Service on or 
after attaining age sixty-two (62) and such benefits shall be calculated in 
accordance with the provisions of Article IV. Except as otherwise provided in 
paragraph (a) of Article IV and in Articles Vll, IX and X, no Participant in 
this Supplemental Plan shall have any vested interest in or right to receive a 
benefit hereunder until attainment of the age of sixty-two (62). Unless 
otherwise determined in writing by the Chief Executive Officer, any 
interruption in the Continuous Service of a Participant herein prior to the 
attainment of age sixty-two (62) shall terminate the participation in this 
Supplemental Plan of such Participant, and no benefit shall be payable to or 
with respect to such Participant.

     (b)  In the sole and unfettered discretion of the Chief Executive 
Officer, a Participant whose Separation from Service occurs prior to 
attainment of age sixty-two (62) may qualify for a special early separation 
benefit, payable monthly as calculated in accordance with the provisions of 
Article IV, except as follows:

       (i)   For purposes of determining the Participant's Base Salary Rate, 
the Average Base Salary Rate and the number of years of Continuous Service 
completed by the Participant, the Participant's date of Separation from 
Service shall apply instead of the date of the Participant's attainment of age 
sixty-two (62); and

       (ii)  For each twelve (12) month period by which the date of 
commencement of the Participant's benefit precedes the Participant's sixty-
second (62nd) birthday, the benefit otherwise payable shall be reduced by five 
percent (5%), except for the benefit payable under paragraph (a) of Article IV 
which shall not be reduced. Proportionate fractional reduction shall be used 
for periods of fewer than twelve (12) months.


                                       4



                                    ARTICLE VI

                             Form of Benefit Payments
                             ------------------------

     (a)  Except as provided in Article Vll, benefits payable based on the 
calculations in Article IV of this Supplemental Plan shall be paid monthly for 
the life-time of the Participant (unless an optional form is selected under 
paragraphs (b) or (c) of this Article Vl). Upon the death of the Participant, 
benefits shall continue to be paid to the Participant's spouse for the 
lifetime of such spouse at the rate of fifty percent (50%) of Participant's 
benefit, provided certain conditions are met. The conditions of such Spousal 
Benefit are (1) that the spouse shall be married to the Participant as of the 
date of the Participant's Separation from Service and (2) the spouse shall be 
no more than five years younger than the Participant. In the event the spouse 
is more than five years younger than the Participant, the Participant may 
elect to receive benefit payments in the form of a joint and survivor option 
as described in paragraph (c) following.

     (b)  Any Participant, who before September 1, 1993 has commenced to 
receive benefits and has not made a written election to receive an annuity 
pursuant to paragraph (a) preceding or paragraph (c) following, shall be 
entitled to one hundred twenty (120) monthly benefit payments in the amount 
specified in paragraph (b) of Article IV preceding and a life annuity of the 
Excess Benefit as defined in paragraph (a) of Article IV preceding. If a 
Participant, who before September 1, 1993, has commenced to receive benefits 
and has not made a written election to receive an annuity pursuant to 
paragraph (a) preceding or paragraph (c) following, dies after Separation from 
Service and before receiving one hundred and twenty (120) monthly benefit 
payments, the remainder of the one hundred and twenty (120) monthly benefit 
payments shall be made to the Participant's designated beneficiary or, if no 
such beneficiary is then living or no such beneficiary can be located, to the 
Participant's estate. In the event a Participant has made a written election, 
prior to September 1, 1993, to receive an annuity pursuant to paragraph (a) 
preceding or paragraph (c) following, no benefit shall be payable under this 
paragraph (b), except that any Excess Benefit under the Pension Plan, as 
provided in paragraph (a) of Article IV, shall be payable at the rate of fifty 
percent (50%) thereof to the Participant's spouse.

     (c)  In the event that the Participant's spouse is more than five years 
younger than Participant, at any time prior to the later of September 1, 1993 
or the commencement of benefits under this Supplemental Plan, a Participant 
may, in lieu of receiving benefits in the form described in paragraph (a) of 
this Article Vl, elect to receive benefit payments under this Supplemental 
Plan in the form of a joint and survivor option providing monthly benefits for 
the lifetime of the Participant with a stipulated percentage of such amount 
continued after the Participant's death to the spouse to whom the Participant 
is married as of the date of the Participant's Separation from Service, for 
the lifetime of such spouse. The amount of monthly 


                                       5



payments available under this option shall be determined by reference to 
factors such as the Participant's life expectancy, the life expectancy of the 
Participant's spouse, prior benefits received under the Supplemental Plan, and 
the percentage of the Participant's monthly benefit which is continued after 
the Participant's death to the Participant's spouse, so that the value of the 
joint and survivor option is the actuarial equivalent of the benefits 
otherwise payable under paragraph (a) (or paragraph (b) if the Participant has 
elected coverage under paragraph (b) preceding) of this Article Vl inclusive 
of the Participant and the spousal fifty percent (50%) survivor benefits, 
which shall be calculated assuming the Participant's spouse was exactly five 
years younger than Participant. In determining the monthly amount payable 
under the joint and survivor option with respect to any Participant, the 
Company may rely upon such information as it, in its sole discretion, deems 
reliable, including but not limited to, the opinion of an enrolled actuary or 
annuity purchase rates quoted by an insurance company licensed to conduct an 
insurance business in the State of California. The election of a joint and 
survivor option is irrevocable after benefit payments have commenced, and the 
monthly amount payable during the lifetime of the Participant shall in no 
event be adjusted by reason of the death of the Participant's spouse prior to 
the death of the Participant, or by reason of the dissolution of the marriage 
between the Participant and such spouse, or for any other reason.


                                   ARTICLE VII

                          Pre-retirement Death Benefits
                          -----------------------------

     In the event of the death of a Participant hereunder during a period of 
Continuous Service and participation in this Supplemental Plan, the 
beneficiary or the spouse of the Participant shall be entitled to benefits as 
provided below in paragraphs (a) and (b):

     (a)  Participant's spouse shall be entitled to a fifty percent (50%) or 
the actuarial equivalent spousal benefit (as determined pursuant to Article 
Vl, paragraphs (a) or (c), as applicable), attributable to Participant's 
Excess Benefit under the Pension Plan provided the Participant is entitled to 
receive a benefit under the Pension Plan.

     (b)  At the written election of the Participant, either a benefit under 
paragraph (i) below or a benefit under paragraph (ii) below shall be paid by 
the Company. Such election shall be signed by the Participant and notarized 
and, if the Participant is married at the time of election, the election must 
also be signed by the Participant's spouse and notarized. The latest election 
on file in the Company's records shall be controlling.

       (i)   A lump sum death benefit shall be payable by the Company to the 
Participant's designated beneficiary or, if no such beneficiary is then living 
or no such beneficiary can be located, to the Participant's estate. 


                                       6



The amount of such death benefit shall be two (2) times the Participant's Base 
Salary Rate in effect on the date of the Participant's death. On the written 
request of a beneficiary but subject to the approval in writing of the Chief 
Executive Officer, the amount payable under this paragraph (b)(i) may be paid 
to a beneficiary in monthly or other installments over a period not exceeding 
one hundred and twenty (120) months. 

       (ii)  Participant's spouse shall receive a spousal fifty percent (50%) 
or the actuarial equivalent spousal benefit (as determined pursuant to Article 
Vl, paragraphs (a) or (c), as applicable), as provided for in paragraph (a) 
preceding and in Article IV and Article Vl. In the event a Participant is not 
married at the time of Participant's death and the Participant has elected the 
fifty percent (50%) spousal benefit, a lump sum death benefit shall be payable 
in accordance with paragraph (b)(i) preceding. 

     No benefits shall be payable under this Article Vll if the Participant's 
death occurs as a result of an act of suicide within twenty-five (25) months 
after commencement of participation in this Supplemental Plan.


                                  ARTICLE VIII

                            No Disability Benefits
                            ----------------------

     No disability benefit is payable under this Supplemental Plan.


                                  ARTICLE IX

              Right to Amend, Modify, Suspend or Terminate Plan
              -------------------------------------------------

     By action of the Company's Board of Directors, the Company may amend, 
modify, suspend or terminate this Supplemental Plan without further liability 
to any employee or former employee or any other person. Notwithstanding the 
preceding sentence, this Supplemental Plan may not be amended, modified, 
suspended or terminated as to a Participant whose Separation from Service has 
occurred and who is entitled to receive or has commenced to receive benefits 
under this Supplemental Plan, without the express written consent of such 
Participant or, if deceased, such Participant's designated beneficiary or, if 
no beneficiary is then living or if no beneficiary can be located, such 
Participant's legal representative.

     If within three (3) years following a Change in Control (as defined in 
Article X) this Supplemental Plan is amended, modified, suspended or 
terminated as to all Participants or as to any Participant who was a 
Participant prior to such Change in Control, such Participant(s) shall become 
fully vested in benefits accrued under this Supplemental Plan as of the date 
of such amendment, modification, 


                                       7



suspension or termination taking into account Continuous Service to such date 
and the Average Base Salary Rate of the Participant(s) as of such date. Upon 
any subsequent Separation from Service, such Participant(s) shall be entitled 
immediately to receive benefits under Articles IV, V, Vl, Vll and X, as 
applicable, as such Articles were in effect on the date of such Change in 
Control, without regard to the approval of the Chief Executive Officer or any 
other person(s).


                                  ARTICLE X

                              Change in Control
                              -----------------

     The term "Change in Control" means, after the effective date of this 
Supplemental Plan, (a) the acquisition by any person, entity or group (as 
defined in Section 13(d)3 of the Securities Exchange Act of 1934, as amended) 
as beneficial owner, directly or indirectly, of securities of the Company 
representing twenty percent (20%) or more of the combined voting power of the 
then outstanding securities of the Company, (b) a change during any period of 
two (2) consecutive years of a majority of the Board of Directors as 
constituted as of the beginning of such period, unless the election of each 
director who was not a director at the beginning of such period was approved 
by vote of at least two-thirds of the directors then in office who were 
directors at the beginning of such period, (c) a sale of substantially all of 
the property and assets of the Company, (d) a merger, consolidation, 
reorganization or other business combination to which the Company is a party 
and the consummation of which results in the outstanding voting securities of 
the Company being exchanged for or converted into cash, property and/or 
securities not issued by the Company, or (e) any other event constituting a 
change in control of the Company for purposes of Schedule 14A of Regulation 
14A under the Securities Exchange Act of 1934.

     In the event a Participant who was a Participant as of the date of a 
Change in Control either (a) has a voluntary Separation from Service for any 
reason (including the death of the Participant) more than twelve (12) full 
calendar months after, but within thirty-six (36) full calendar months 
following, such Change in Control, or (b) has an involuntary Separation from 
Service for any reason within thirty-six full calendar months following such 
Change in Control, such Participant shall be entitled to receive immediately 
upon such Separation from Service benefits hereunder in accordance with 
Articles IV, Vl and Vll, as applicable, without regard to approval by the 
Chief Executive Officer or any other person(s).  Such benefits shall be 
calculated as if, on the date of such Separation from Service, the Participant 
(i) had completed a number of years of Continuous Service equal to the greater 
of twelve (12) or the actual number of years of his or her Continuous Service, 
and (ii) had attained an age equal to the greater of sixty-two (62) or his or 
her actual age.

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

     Benefits under this Supplemental Plan may not be assigned or alienated 
and shall not be subject to the claims of any creditor.


                                 ARTICLE XII

                                Administration
                                --------------

     This Supplemental Plan shall be administered by the Chief Executive 
Officer or by such other person or persons to whom the Chief Executive Officer 
may delegate functions hereunder. With respect to all matters pertaining to 
this Supplemental Plan, the determination of the Chief Executive Officer or 
his designated delegate shall be conclusive and binding. The Chief Executive 
Officer shall be eligible to participate in this Supplemental Plan in the same 
manner as any other employee; provided, however, that the designation of the 
Chief Executive Officer as a Participant and any other action provided herein 
with respect to the Chief Executive Officer's participation shall be taken by 
the Compensation Committee of the Board of Directors of the Company.

                                  -------

     In connection with any benefit or benefit payment under this Supplemental 
Plan, or the designation of any beneficiary or any election or other action 
taken or to be taken under the Supplemental Plan by any Participant or any 
other person, the Company, acting through its Chief Executive Officer or his 
delegate, may require such consents or releases as are reasonable under the 
circumstances, and further may require any such designation, election or other 
action to be in writing and in form reasonably satisfactory to the Chief 
Executive Officer or his delegate.

                                  ---------

     The failure of the Company, the Chief Executive Officer or any other 
person acting on behalf thereof to demand a Participant or other person 
claiming rights with respect to a Participant to perform any act which such 
person is or may be required to perform hereunder shall not constitute a 
waiver of such requirement or a waiver of the right to require such act. The 
exercise of or failure to exercise any discretion reserved to the Company, its 
Chief Executive Officer or his delegate, to grant or deny any benefit to any 
Participant or other person under this Supplemental Plan shall in no way 
require the Company, its Chief Executive Officer 


                                       9



or his delegate to similarly exercise or fail to exercise such discretion with 
respect to any other Participant.

                                  No Contract
                                  -----------

     This Supplemental Plan is strictly a voluntary undertaking on the part of 
the Company and shall not be deemed to constitute a contract or part of a 
contract between the Company (or an Affiliate) and any employee or other 
person, nor shall it be deemed to give any employee the right to be retained 
for any specified period of time in the employ of the Company (or an 
Affiliate) or to interfere with the right of the Company (or an Affiliate) to 
discharge or retire any employee at any time, nor shall this Supplemental Plan 
interfere with the right of the Company (or an Affiliate) to establish the 
terms and conditions of employment of any employee.


                                 ARTICLE XVI

                               Indemnification
                               ---------------

     The Company shall defend, indemnify and hold harmless the Officers and 
Directors of the Company acting in their capacity as such (and not as 
Participants herein) from any and all claims, expenses and liabilities arising 
out of their actions or failure to act hereunder, excluding fraud or willful
