3.50% Notes due April
15, 2008 
 
This security is one of a duly authorized series of
debt securities of Computer Sciences Corporation, a Nevada corporation (the “Company”) issued or to be issued in one or more series under and pursuant to an Indenture for the Company’s unsubordinated debt securities, dated as of
February 10, 2003 (the “Base Indenture”), duly executed and delivered by and between the Company and Citibank, N.A. (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of February 14, 2003 (the
“First Supplemental Indenture”), by and between the Company and the Trustee and the Second Supplemental Indenture, dated as of April 3, 2003 (the “Second Supplemental Indenture”), by and between the Company and the Trustee. The
Base Indenture as supplemented and amended by the First Supplemental Indenture and the Second Supplemental Indenture shall be referred to herein as the “Indenture.” By the terms of the Base Indenture, the debt securities issuable
thereunder are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Base Indenture. This security is one of the series designated on the face hereof (individually, a
“Security,” and collectively, the “Securities”), and reference is hereby made to the Indenture for a description of the rights, limitations of rights, obligations, duties and immunities of the Trustee, the Company and the holders
of the Securities (“Securityholders”). Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Base Indenture or the Second Supplemental Indenture, as applicable. 
 
1.    Interest.    The Company promises to pay interest on the principal amount of this Security at a rate per annum of 3.50%. The Company will pay interest semi-annually on April 15 and
October 15 of each year (each such day, an “Interest Payment Date”). If any Interest Payment Date, redemption date or maturity date of this Security is not a Business Day, then payment of interest or principal (and premium, if any) shall
be made on the next succeeding Business Day with the same force and effect as if made on the date such payment was due, and no interest shall accrue for the period after such date to the next succeeding Business Day. Interest on the Securities will
accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid, from the date of issuance; provided that, if there is no existing Default in the payment of interest, and if this Security is
authenticated between a regular record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; and provided, further, that the first Interest Payment
Date shall be October 15, 2003. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 
2.    Method of Payment.    The Company will pay interest on the Securities (except
defaulted interest), if any, to the persons in whose name such Securities are registered at the close of business on the regular record date referred to on the facing page of this Security for such interest installment. In the event that the
Securities or a portion thereof are called for redemption and the Redemption Date is subsequent to a regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest on such Securities will be paid upon
presentation and surrender of such Securities as provided in the Indenture. The principal of and the interest on the Securities shall be payable in the coin or currency of the 






United States of America that at the time is legal tender for public and private debt, at the office or
agency of the Company maintained for that purpose in accordance with the Indenture. 
 
3.    Paying Agent and Registrar.    Initially, Citibank, N.A., the Trustee, will act as paying agent and Security Registrar. The Company may change or
appoint any paying agent or Security Registrar without notice to any Securityholder. The Company may act in any such capacity. 
 
4.    Indenture.    The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939 (“TIA”) as in effect on the date the Indenture is qualified. The Securities are subject to all such terms, and Securityholders are referred to the Indenture
and TIA for a statement of such terms. The Securities are unsecured general obligations of the Company and constitute the series designated on the face hereof as the “3.50% Notes due April 15, 2008”, initially limited to $300,000,000 in
aggregate principal amount. 
 
The Company will
furnish to any Securityholder upon written request and without charge a copy of the Base Indenture and the Second Supplemental Indenture. Requests may be made to: Computer Sciences Corporation, 2100 East Grand Avenue, El Segundo, California 90245,
Attention: Corporate Secretary. 
 
5.    Optional Redemption.    The Securities will be subject to redemption at the option of the Company on any date prior to the maturity date, in whole or from time to time in part, in
$1,000 increments (provided that any remaining principal amount thereof shall be at least the minimum authorized denomination thereof), on written notice given to the Securityholders thereof not less than 30 days nor more than 90 days prior
to the date fixed for redemption in such notice (the “Redemption Date”), at a redemption price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed and (ii) the sum of the present values of the
Remaining Scheduled Payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date, on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months), at the Treasury Rate plus 15 basis points (such greater amount is referred to herein as the “Redemption Price”), plus, in either the case of clause (i) or clause (ii), accrued and unpaid interest thereon to the
Redemption Date.  
 
If the giving of the
notice of redemption is completed as provided in the Indenture, interest on such Securities or portions of Securities shall cease to accrue on and after the Redemption Date, unless the Company shall default in the payment of such redemption price
and accrued interest with respect to any such Security or portion thereof. 
 
The Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Securities. 
 
6.    Denominations, Transfer, Exchange.    The Securities are
in registered form without coupons in the denominations of $1,000 or any integral multiple of $1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Securities may be presented for
exchange or for registration of transfer (duly endorsed or 






with the form of transfer endorsed thereon duly executed if so required by the Company or the Security
Registrar) at the office of the Security Registrar or at the office of any transfer agent designated by the Company for such purpose. No service charge will be made for any registration of transfer or exchange, but a Securityholder may be required
to pay any applicable taxes or other governmental charges. If the Securities are to be redeemed, the Company will not be required to: (i) issue, register the transfer of, or exchange any Security during a period beginning at the opening of business
15 days before the day of mailing of a notice of redemption of less than all of the outstanding Securities of the same series and ending at the close of business on the day of such mailing; (ii) register the transfer of or exchange any Security of
any series or portions thereof selected for redemption, in whole or in part, except the unredeemed portion of any such Security being redeemed in part; nor (iii) register the transfer of or exchange a Security of any series between the applicable
record date and the next succeeding Interest Payment Date. 
 
7.    Persons Deemed Owners.    The registered Securityholder of a Security may be treated as its owner for all purposes. 
 
8.    Amendments, Supplements and Waivers.    The Base
Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Outstanding debt securities of each series affected by such supplemental indenture
or indentures (including the Securities, if applicable) to execute supplemental indentures for the purpose of adding or eliminating any provisions to the Base Indenture or of modifying in any manner the rights of the holders of the securities of
such series; provided, however, that no such supplemental indenture shall, without the consent of each holder of Outstanding securities affected thereby: (i) extend a fixed maturity of or any installment of principal of any securities
of any series or reduce the principal amount thereof, or reduce the amount of principal of any original issue discount security that would be due and payable upon declaration of acceleration of the maturity thereof; (ii) reduce the rate of or extend
the time for payment of interest of any Security of any series; (iii) reduce the premium payable upon the redemption of any Security; (iv) make any Security payable in Currency other than that stated in the Security; (v) impair the right to
institute suit for the enforcement of any payment on or after the fixed maturity thereof (or in the case or redemption, on or after the redemption date); or (vi) reduce the percentage in principal amount of the Outstanding debt securities of any
series issued pursuant to the Base Indenture, the holders of which are required to consent to any such supplemental indenture or indentures. The Base Indenture also contains provisions permitting the holders of not less than a majority in aggregate
principal amount of the Outstanding debt securities of each series affected thereby, on behalf of all of the holders of the securities of such series, to waive any past Default under the Base Indenture, and its consequences, except a Default in the
payment of the principal of, premium, if any, or interest on any security of such series or a Default in respect of a covenant or provision of the Base Indenture which cannot be modified or amended without the consent of the holder of each
Outstanding security of such affected series. Any such consent or waiver by the registered holder of this Security shall be conclusive and binding upon such holder and upon all future holders and owners of this Security and of any Security issued in
exchange for this Security or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Security. 






 
9.    Defaults and Remedies.    Events of Default under the Indenture include, with respect to the debt securities of any series issued pursuant to the Base Indenture (including the
Securities): (i) failure to pay interest when due and such failure continues for 90 days and the time for payment has not been extended or deferred; (ii) failure to pay the principal (or premium, if any) when due; (iii) failure to observe or perform
any other covenant contained herein or in the Indenture with respect to the series of debt securities, and such failure continues for 90 days after the Company has received notice from the Trustee or the holders of at least 25% in aggregate
principal amount of the Outstanding securities of the series; and (iv) certain events of bankruptcy, insolvency or reorganization of the Company. If an Event of Default with respect to the debt securities of a series issued pursuant to the Base
Indenture occurs and is continuing, the Trustee or the holders of at least 25% in aggregate principal amount of the Outstanding securities of such series, by notice in writing to the Company (and to the Trustee if notice is given by such holders),
may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. Subject to the terms of the Indenture, if an Event of Default under the Indenture shall occur and be continuing, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders, unless such holders have offered the Trustee indemnity satisfactory to it. Upon satisfaction of certain conditions set
forth in the Indenture, the holders of a majority in principal amount of the Outstanding debt securities of a series issued pursuant to the Base Indenture will have the right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the securities of such series. 
 
10.    No Recourse Against Others.    No recourse under or upon any obligation, covenant or
agreement of the Indenture, or of any Security, or for any claim based thereon or otherwise in respect hereof or thereof, shall be had against any incorporator, stockholder, officer or director, past, present or future as such, of the Company or of
any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly understood that the Indenture and the obligations issued hereunder and thereunder are solely corporate obligations, and that no such personal liability whatever shall attach to, or is or shall be incurred by, the
incorporators, stockholders, officers or directors as such, of the Company or of any predecessor or successor corporation, or any of them, because of the creation of the indebtedness authorized by the Indenture, or under or by reason of the
obligations, covenants or agreements contained in the Indenture or in any of the Securities or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution or statute,
of, and any and all such rights and claims against, every such incorporator, stockholder, officer or director as such, because of the creation of the indebtedness authorized by the Indenture, or under or by reason of the obligations, covenants or
agreements contained in the Indenture or in the Securities or implied therefrom, are hereby expressly waived and released as a condition of, and as a consideration for, the acceptance of the Securities. 
 
11.    Discharge of
Indenture.    The Indenture contains certain provisions pertaining to defeasance, which provisions shall for all purposes have the same effect as if set forth herein. 






 
12.    Authentication.    This Security shall not be valid until the Trustee signs the certificate of authentication attached to the other side of this Security. 
 
13.    Abbreviations.    Customary abbreviations may be used in the name of a Securityholder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
 
14.    Governing Law.    The Base Indenture, the Second Supplemental Indenture and the
Securities shall be construed in accordance with and governed by the laws of the State of New York.
