                               PG&E CORPORATION
                       EXECUTIVE STOCK OWNERSHIP PROGRAM

                           Administrative Guidelines
                           -------------------------
                        (As amended September 19, 2000)

1.   Description. The Executive Stock Ownership Program ("Program") was approved
     -----------
     by the Nominating and Compensation Committee of the Board of Directors on
     October 15, 1997. The Program is an important element of the Committee's
     compensation policy of aligning executive interests with those of the
     Corporation's shareholders. As an integral part of the Program, the
     Committee also authorized the use of Special Incentive Stock Ownership
     Premiums ("SISOPs") which are designed to provide incentives to Eligible
     Executives to assist in achieving minimum stock ownership targets
     established by the Committee. These Guidelines were originally adopted by
     the Committee on November 19, 1997, amended by the Committee on July 22,
     1998, October 21, 1998, February 16, 2000, and September 19, 2000. These
     amended Guidelines, along with the written materials provided to the
     Committee on October 15, 1997, describe the Program which became effective
     on January 1, 1998. The Program is administered by the Corporation's Senior
     Human Resources Officer.

2.   Eligible Executives.  The Chief Executive Officer shall designate the
     -------------------
     officers of the Corporation and its affiliates who shall be Eligible
     Executives covered by the Program. The officers covered by the Guidelines
     and the applicable total stock ownership target ("Target") are:

     ---------------------------------------------------------------------------
       Officer Band                Position                    Total Stock
                                                             Ownership Target
     ---------------------------------------------------------------------------

            1                        CEO                       3 x base salary
     ---------------------------------------------------------------------------
            2               Heads of Business Lines,           2 x base salary
                            CFO, & General Counsel
     ---------------------------------------------------------------------------
            3               SVPs of Corp. & Utility            1.5 x base salary
     ---------------------------------------------------------------------------

3.   Annual Milestones.   Under the Guidelines, Targets are designed to be
     -----------------
     achieved by the end of the fifth calendar year following the calendar year
     in which an officer first becomes an Eligible Executive ("Target Date").
     Annual Milestones have been established as a means of measuring progress
     towards achieving Targets and of providing incentives for Eligible
     Executives to expeditiously meet their Targets. The Annual Milestone at the
     end of the first full calendar year is 20 percent of the Target, and the
     Annual Milestone for each succeeding year is an additional 20 percent of
     the Target. Annual Milestones shall be adjusted to reflect changes in base
     salary; provided, however, that in each instance any such modification
     shall be amortized over the remaining original five-year term. Following
     the Target Date, Targets also shall be modified to reflect changes in base
     salary.

4.   Calculation of Stock Ownership Levels. Stock ownership level is the dollar
     -------------------------------------
     value of stock and stock equivalents owned by an Eligible Executive and
     calculated as of the last day of the calendar year ("Measurement Date").
     The purpose of this calculation is to determine the value of the stock or
     stock equivalents owned by the Eligible Executive as compared with the
     Annual Milestone or Target for that executive. For purposes of this
     calculation, the value per share of stock or stock equivalent ("Measurement
     Value") is the average closing price of PG&E Corporation common stock as
     traded on the New York Stock Exchange for the last thirty (30) trading days
     of the year.

     a)   The value of stock beneficially owned by the Eligible Executive is
          determined by multiplying the number of shares owned beneficially on
          the Measurement Date times the Measurement Value.

     b)   The value of PG&E Corporation phantom stock units credited to the
          Eligible Executive's account in the PG&E Corporation Supplemental
          Retirement Savings Plan ("SRSP") is determined by multiplying the
          number of phantom stock units credited to the Eligible Executive's
          SRSP account on the Measurement Date times the Measurement Value.

     c)   The value of stock held in the PG&E Corporation stock fund of any
          defined contribution plan maintained by PG&E Corporation or any of its
          subsidiaries is determined by multiplying the number of shares in such
          plan on the Measurement Date times the Measurement Value.

     d)   For Eligible Executive's whose Target Date is on or before 12/31/2004,
          the value of the frozen share-equivalent units of the vested "in the
          money" stock options as of 12/31/2000. The value of the frozen share-
          equivalent units of the vested "in the money" stock options is the
          difference between the number of options on 12/31/2000 multiplied by
          the Measurement Value on 12/31/2000 minus the number of options on
          12/31/2000 multiplied by the option exercise price (for purposes of
          this calculation, any value attributable to dividend equivalents is
          excluded).

5.   Award of SISOPs. SISOPs are awarded to Eligible Executives who achieve and
     ---------------
     maintain stock ownership levels prior to the end of the third year
     following the year in which an officer first became an Eligible Executive.
     For purposes of determining awards, the total stock ownership level is
     calculated as set forth under paragraph 4, on the Measurement Date. The
     amount of a SISOP award shall be equal to:

     a)   For the first year, 20 percent of the amount of the Eligible
          Executive's stock ownership level at the end of the year, up to the
          Annual Milestone, plus an additional 30 percent of the amount by which
          the stock ownership level exceeds the Annual Milestone up to the
          Target; and

     b)   For each of the second and third years, the current stock ownership
          level is reduced by the stock ownership level used to calculate
          previous SISOP awards to determine the new ownership then 20 percent
          of the amount up to the Annual Milestone by which the end of the year
          stock ownership level exceeds the beginning of the year stock
          ownership level, plus an additional 30 percent of the amount by which
          the end of the year balance exceeds the Annual Milestone, up to the
          Target.

                                       2
<PAGE>

     Each time a SISOP award calculation is made, a second calculation also is
     made to determine the minimum number of shares which must be retained by
     the Eligible Executive to avoid forfeiture of the SISOP award ("Minimum
     Ownership Level") as discussed below in paragraph 8. This calculation
     converts the dollar value of the stock ownership level used as the basis
     for qualifying for SISOPs into a number of shares of stock. It is
     calculated by dividing the stock ownership level by the Measurement Value.
     Thus, for example, if an Eligible Executive's stock ownership level was
     $250,000 and the Measurement Value was $25 per share, then the Minimum
     Ownership Level would be 10,000 shares.

     For purposes of this calculation, the maximum share ownership level used is
     the Eligible Executive's Target.  If an Eligible Executive has a share
     ownership level higher than his/her Target, the increment over the Target
     is not included.  Thus, for example, if an Eligible Executive has a Target
     of $750,000 and his/her share ownership level is $900,000, then only
     $750,000 is used to calculate the Minimum Ownership Level.

6.   SISOPs Credited to the SRSP. Upon award, SISOPs are credited to the
     ---------------------------
     Eligible Executive's SRSP account and converted into units of phantom stock
     each equal in value to a share of PG&E Corporation common stock ("SISOP
     units") as determined in accordance with the SRSP. The SISOP units
     constitute "incentive awards" authorized to be awarded by the Committee to
     Eligible Executives under the PG&E Corporation Long-Term Incentive Program
     ("LTIP"). Upon credit of SISOP units to an Eligible Executive's SRSP
     account, an equal number of shares of PG&E Corporation common stock shall
     be reserved for issuance from the pool of shares authorized for issuance
     under the LTIP. Once a SISOP unit is credited to the Eligible Executive's
     SRSP account, it shall be subject to all of the terms and conditions
     specifically applicable to SISOP units under the SRSP. Once vested in
     accordance with paragraph 7 below, SISOP units are distributed in the form
     of an equal number of shares of PG&E Corporation common stock as provided
     in the SRSP.

7.   Vesting. SISOPs vest only upon the expiration of three years after the date
     -------
     of award (provided the Eligible Executive continues to be employed on such
     date), or, if earlier, upon an Eligible Executive's death, disability,
     Retirement, upon a Change in Control, as defined in the LTIP, or upon a
     termination of employment coincident with the sale of all or substantially
     all of the assets of a subsidiary of PG&E Corporation. An Eligible
     Executive's unvested SISOPs will be forfeited upon termination of
     employment unless otherwise provided in the PG&E Corporation Officer
     Severance Policy or by another separation agreement

8.   Forfeiture of SISOP Units. So long as SISOP units remain unvested, such
     -------------------------
     units are subject to forfeiture if, on each Measurement Date, the Eligible
     Executive's stock ownership is less than the Minimum Ownership Level
     established when the SISOPs were granted (see paragraph 5). To determine
     forfeiture, the following steps are followed on each Measurement Date:

     a)   The total stock and stock equivalents owned by an Eligible Executive
          is determined as set forth under paragraph 4. This total ("Current
          Holdings") is compared with the Minimum Ownership Level determined
          when the SISOPs were granted. If the Current Holdings are equal to or
          greater than the Minimum Ownership Level, then no unvested SISOP units
          are forfeited. If the Current Holdings are less than the Minimum
          Ownership Level, then the unvested SISOP units are forfeited in the
          same proportion as the Current Holdings are less than Minimum
          Ownership Level (for

                                       3
<PAGE>

          example, if the Current Holdings are 20 percent less than the Minimum
          Ownership Level, then 20 percent of the SISOP units are forfeited).

9.   Failure to Achieve or Maintain Target. Failure to achieve stock ownership
     -------------------------------------
     levels at Target on the Target Date, or to maintain stock ownership levels
     at Target on any Measurement Date thereafter, will result in the deferral
     into the PG&E Corporation Phantom Stock Fund of the SRSP of annual awards
     from the Performance Unit Plan ("PUP") and the Short-Term Incentive Plan
     ("STIP"). As of any Measurement Date, to the extent that stock ownership
     levels are below Target, PUP awards shall be converted into PG&E
     Corporation Phantom Stock Units and held in the PG&E Corporation Phantom
     Stock Fund of the SRSP. If, with the addition of the phantom stock units
     attributable to the PUP award, the stock ownership level is still below
     Target for any Measurement Date, any STIP award above target STIP also
     shall be converted into phantom stock units, to the extent necessary to
     achieve the Target stock ownership level. Such conversion of PUP and STIP
     awards shall continue for successive Measurement Dates, if necessary, until
     Target is met. Phantom stock units attributable to PUP and STIP awards
     described in this paragraph 9 will be paid from the SRSP in a lump sum in
     January of the year following the year in which the Eligible Executive's
     employment terminates, or upon such earlier date as may have been elected
     by the Eligible Executive within thirty days after the date of mandatory
     deferral of PUP and/or STIP awards which date shall not be earlier than
     three (3) years after the date of mandatory deferral.

                             OFFICERS' CERTIFICATE
                     PURSUANT TO SECTIONS 201, 301 AND 303
                                OF THE INDENTURE

          The undersigned, John H. Mullan and David H. Strode, do hereby certify
that they are the duly appointed and acting Corporate Vice President and
Secretary, and the Assistant Treasurer, respectively, of Northrop Grumman
Corporation, a Delaware corporation (the "Company").  Each of the undersigned
also hereby certifies, pursuant to Sections 201, 301 and 303 of the Indenture,
dated as of October 15, 1994 (the "Indenture"), between the Company and The
Chase Manhattan Bank, as Trustee (the "Trustee"), that:

          A.  There is hereby established pursuant to resolutions duly adopted
by the Board of Directors of the Company on January 23, 2001, two series of
Securities (as defined in the Indenture) to be issued under the Indenture, with
the following terms (defined terms used herein and not otherwise defined herein
have the meaning set forth in the Indenture):

                         I.    7-1/8 % Notes due 2011

          (1)  The title of the Securities of the series is "7-1/8% Series A
     Notes due 2011" (the "Series A Notes") and "7-1/8% Series B Notes due 2011"
     (the "Series B Notes" and, together with the Series A Notes, the "Notes").

          (2)  The aggregate principal amount of the Notes which initially may
     be authenticated and delivered under the Indenture (except for Notes
     authenticated and delivered upon registration of transfer of, or in
     exchange for, or in lieu of, other Notes of the series pursuant to Sections
     304, 305, 306, 906 or 1107 of the Indenture and except for any Securities
     which, pursuant to Section 303 of the Indenture, are deemed never to have
     been authenticated and delivered hereunder) is $750,000,000. The Company
     may, without the consent of the holders of the Notes, issue additional
     notes having the same ranking, interest rate, maturity, CUSIP number and
     other terms as the Notes. Any additional notes having such similar terms,
     together with the Notes, would constitute a single series of Notes under
     the Indenture. No additional notes may be issued if an Event of Default has
     occurred and is continuing with respect to the Notes.

          (3)  Interest on the Notes shall be payable to the persons in whose
     names the Notes are registered at the close of business on the Regular
     Record Date (as specified in paragraph I(5) below) for such interest
     payment.

                                      -1-
<PAGE>

          (4)  The principal of the Notes shall be payable, unless accelerated
     or earlier redeemed or repurchased pursuant to the Indenture, on February
     15, 2011.

          (5)  The rate at which each of the Notes shall bear interest shall be
     7-1/8% per annum; provided, that in the event of a Non-Registration Event
                       --------
     (as defined in the Registration Rights Agreement dated as of February 27,
     2001 by and among the Company and the initial purchasers identified therein
     (the "Registration Rights Agreement")) with respect to the Notes,
     additional interest will accrue on the Notes at an annual rate of .25% for
     the first 90-day period immediately following the occurrence of a Non-
     Registration Event, and such annual rate will increase by an additional
     .25% with respect to each subsequent 90-day period until all Non-
     Registration Events have been cured, up to a maximum additional annual
     interest rate of 1.0%. The additional interest will accrue from and
     including the date on which any such Non-Registration Event shall occur to
     but excluding the date on which all such Non-Registration Events have been
     cured. The Company will pay such additional interest on each Interest
     Payment Date. Such additional interest will be in addition to any other
     interest payable from time to time with respect to the Notes. Interest on
     the Notes shall be computed on the basis of a 360-day year of twelve 30-day
     months. The date from which interest shall accrue for each of the Notes
     shall be February 27, 2001. The Interest Payment Dates on which interest on
     the Notes shall be payable are February 15 and August 15, commencing August
     15, 2001. The Regular Record Date for the interest payable on the Notes on
     any Interest Payment Date shall be the February 1 or August 1 (whether or
     not a Business Day), as the case may be, next preceding such Interest
     Payment Date.

          (6)  The principal of and interest on the Notes shall be payable in
     immediately available funds at the office or agency of the Company
     maintained for that purpose in the Borough of Manhattan, the City of New
     York (as of the date of this Officers' Certificate, such office being
     located at the office of the Trustee, 450 West 33rd Street, 15th Floor, New
     York, New York 10001, Attention: Institutional Trust Services), in such
     coin or currency of the United States of America as at the time of payment
     is legal tender for payment of public and private debts, provided, however,
     that at the option of the Company payment of interest may be made by wire
     transfer in immediately available funds to an account maintained by the
     person entitled thereto as specified in the Security Register.

          (7)  Northrop Grumman may redeem all or part of the Notes at any time
     at its option at a redemption price equal to the greater of (a) the
     principal amount of the Notes being redeemed plus accrued and unpaid
     interest to the redemption date or (b) the Make-Whole Amount for the Notes
     being redeemed.

                                      -2-

     As used in this Section I(7):

               "Adjusted Treasury Rate" means, with respect to any Redemption
     Date, (i) the yield, under the heading which represents the average for the
     immediately preceding week, appearing in the most recently published
     statistical release designated "H.15 (519)" or any successor publication
     which is published weekly by the Board of Governors of the Federal Reserve
     System and which establishes yields on actively traded United States
     Treasury securities adjusted to constant maturity under the caption
     "Treasury Constant Maturities," for the maturity corresponding to the
     Comparable Treasury Issue (if no maturity is within three months before or
     after the remaining term of the Notes being redeemed, yields for the two
     published maturities most closely corresponding to the Comparable Treasury
     Issue shall be determined and the Adjusted Treasury Rate shall be
     interpolated or extrapolated from such yields on a straight line basis,
     rounding to the nearest month) or (ii) if such release (or any successor
     release) is not published during the week preceding the calculation date or
     does not contain such yields, the rate per year equal to the semi-annual
     equivalent yield to maturity of the Comparable Treasury Issue (expressed as
     a percentage of its principal amount) equal to the Comparable Treasury
     Price for such Redemption Date, in each case calculated on the third
     Business Day preceding the Redemption Date, plus .25%.

          "Comparable Treasury Issue" means the United States Treasury security
     selected by the Quotation Agent as having a maturity comparable to the
     remaining term from the Redemption Date to the Stated Maturity of the
     principal amount of the Notes being redeemed that would be utilized, at the
     time of selection and in accordance with customary financial practice, in
     pricing new issues of corporate debt securities of comparable maturity to
     the remaining term of the Notes being redeemed.

          "Comparable Treasury Price" means, with respect to any Redemption
     Date, if clause (ii) of the Adjusted Treasury Rate is applicable, the
     average of three, or such lesser number as is obtained by the Trustee,
     Reference Treasury Dealer Quotations for such Redemption Date.

          "Make Whole Amount" means the sum, as determined by a Quotation Agent,
     of the present values of the principal amount of the Notes to be redeemed,
     together with scheduled payments of interest (exclusive of interest to the
     Redemption Rate) from the Redemption Date to the Stated Maturity of the
     principal amount of the Notes being redeemed, in each case discounted to
     the Redemption Date on a semi-annual basis, assuming a 360-day year
     consisting of twelve 30-day months, at the Adjusted Treasury Rate, plus
     accrued and unpaid

                                      -3-
<PAGE>

     interest on the principal amount of the Notes being redeemed to the
     Redemption Date.

          "Quotation Agent" means the Reference Treasury Dealer selected by the
     Trustee after consultation with the Company.

          "Reference Treasury Dealer" means any of Chase Securities Inc. and
     Credit Suisse First Boston Corporation, and their respective successors and
     assigns, and one other nationally recognized investment banking firm
     selected by the Company that is a primary U.S. Government securities
     dealer.

          "Reference Treasury Dealer Quotations" means, with respect to each
     Reference Treasury Dealer and any Redemption Date, the average, as
     determined by the Trustee, of the bid and asked prices for the Comparable
     Treasury Issue, expressed in each case as a percentage of its principal
     amount, quoted in writing to the Trustee by such Reference Treasury Dealer
     at 5:00 p.m., New York City time, on the third Business day preceding such
     Redemption Date.

          (8)  There is no obligation of the Company to redeem or purchase the
     Notes pursuant to any sinking fund or analogous provisions or to redeem or
     purchase any of the Notes prior to the Stated Maturity at the option of the
     Holder thereof.

          (9)  There is no provision for the conversion or exchange of the
     Notes, either at the option of the Holder thereof or the Company, into or
     for another security or securities of the Company.

          (10) The Notes shall be issued only in fully registered form without
     coupons in denominations of $1,000 and integral multiples thereof.

          (11) The entire principal amount of the Notes shall be payable upon
     declaration of acceleration of the maturity thereof pursuant to Section 502
     of the Indenture.

          (12) Except as provided in subparagraph (13) below, the Notes shall be
     issued in the form of one or more Global Securities, in accordance with and
     subject to the provisions of Section 305 of the Indenture and as follows
     (all references in this Section I to Global Securities shall be with
     respect to the Notes):

              (a)  Notes sold within the United States to qualified
     institutional buyers ("QIBs"), as defined under Rule 144A under the
     Securities Act of 1933, as amended (the "Securities Act"), initially will
     be represented by one or more Global Securities (the "144A Global Notes"),
     and Notes sold outside of the United States in reliance on Regulation S
     under the Securities

                                      -4-
<PAGE>

      Act initially will be represented by one or more Global Securities (the
     "Regulation S Global Notes" and, together with the 144A Global Notes, the
     "Global Notes"). The Global Notes will be deposited upon issuance with the
     Trustee as custodian for The Depository Trust Company (the "DTC") and
     registered in the name of DTC or its nominee, in each case for credit to an
     account of a direct or indirect participant in DTC.

               (b)  Through and including the 40th day after the later of the
     commencement of the offering of the Notes and the closing of the offering
     (such period the "Restricted Period"), beneficial interests in the
     Regulation S Global Notes may be held only through the Euroclear System
     ("Euroclear") and Clearstream Banking S.A. ("Clearstream") (as indirect
     participants in DTC), unless transferred to a person that takes delivery
     though a 144A Global Note in accordance with certain certification
     requirements.

               (c)  Investors in the 144 Global Notes who are participants in
     DTC's system ("Participants") may hold their interests therein directly
     through DTC. Investors in the 144A Global Notes who are not Participants
     may hold their interests therein indirectly through organizations
     (including Euroclear and Clearstream) which are Participants in such
     system. Investors in the Regulation S Global Notes must initially hold
     their interests therein through Euroclear or Clearstream, if they are
     participants in such systems, or indirectly through organizations that are
     participants in such systems. After the expiration of the Restricted Period
     (but not earlier), investors may also hold interests in the Regulation S
     Global Notes through Participants in the DTC system other than Euroclear
     and Clearstream. Euroclear and Clearstream will hold interests in the
     Regulation S Global Notes on behalf of their participants through
     customers' security accounts in their respective names on the books of
     their respective depositories. All interests in Global Notes, including
     those held through Euroclear or Clearstream, may be subject to the
     procedures and requirements of DTC. Those interests held through Euroclear
     or Clearstream may also be subject to the procedures and requirements of
     such systems.

               (d)  Transfers between participants in DTC will be effected in
     accordance with DTC's procedures, and will be settled in same-day funds,
     and transfers between participants in Euroclear and Clearstream will be
     effected in accordance with their respective rules and operating
     procedures.

               (e)  Prior to the expiration of the Restricted Period, beneficial
     interests in Regulation S Global Notes may be exchanged for beneficial
     interests in 144A Global Notes only if (a) such exchange occurs in

                                      -5-
<PAGE>

     connection with a transfer of the Notes pursuant to Rule 144A; and (b) the
     transferor first delivers to the Trustee a written certificate in the form
     attached hereto as Annex I to the effect that the Notes are being
                        -------
     transferred to a person (i) who the transferor reasonably believes to be a
     QIB; (ii) purchasing for its own account or the account of a QIB in a
     transaction meeting the requirements of Rule 144A; and (iii) in accordance
     with all applicable securities laws of the states of the United States and
     other jurisdictions.

          (f)  Beneficial interests in 144A Global Notes may be transferred to a
     person who takes delivery in the form of an interest in Regulation S Global
     Notes, whether before or after the expiration of the Restricted Period,
     only if the transferor first delivers to the Trustee a written certificate
     in the form attached hereto as Annex I to the effect that such transfer is
                                    -------
     being made in accordance with Rule 903 or 904 of Regulation S or Rule 144
     (if available) and that, if such transfer occurs prior to the expiration of
     the Restricted Period, the interest transferred will be held immediately
     thereafter through Euroclear or Clearstream.

          (g)  In addition to the circumstances set forth in clause (2) of
     Section 305 of the Indenture with respect to the exchange of Global Notes
     for Notes registered in definitive form, Notes issued as Global Notes may
     be exchanged in whole or in part for registered Notes if the Company in its
     discretion at any time determines not to have all the Notes represented by
     Global Notes; and provided, that clause (B) of clause (2) of Section 305 of
                       --------
     the Indenture shall apply only if the Event of Default referred to therein
     has occurred and is continuing and entitles the Holders to accelerate the
     maturity of the Notes. Subject to the foregoing and to paragraph I(13)
     hereof, the Global Notes are not exchangeable, except for a Global Note or
     Global Notes of the same aggregate denomination to be registered in the
     name of DTC or its nominee.

          (13) Subject to the provisions of paragraph I(12) above, Notes that
     are (i) originally issued to or transferred to an institutional "accredited
     investor" as defined in Rule 501(a)(1), (2), (3) or (7) under the
     Securities Act who is not a QIB or (ii) issued as certificated securities
     pursuant to the Indenture will be issued in definitive form. Upon the
     transfer to a QIB of a Note in definitive form, such Note will, unless the
     Global Note in respect of such Note has previously been exchanged for Notes
     in definitive form, be exchanged for an interest in the Global Note
     representing the principal amount of the Note being transferred.

          (14) There shall be added to Section 501 of the Indenture the
     following additional Events of Default with respect to the Notes:

                                      -6-
<PAGE>

                "(8) the failure of a Guarantor to promptly execute its
                     guaranty of the Notes upon the occurrence of the Guarantee
                     Event, or

                (9)  except as permitted by the Indenture or the Guarantee, any
                     Guarantee shall be held in any judicial proceeding to be
                     unenforceable or invalid or shall cease for any reason to
                     be in full force and effect or any Guarantor, or any entity
                     or person acting on behalf of the Guarantor, shall deny or
                     disaffirm its obligations under the Guarantor's Guarantee."

          (15) Upon the occurrence of the Guarantee Event the Notes shall be
     entitled to the benefit of guarantees to be executed by NNG and Litton,
     respectively (individually a "Guarantor" and collectively "Guarantors"), in
     the forms of the guarantees attached hereto as Exhibits A and B,
                                                    ----------------
     respectively, and incorporated herein by this reference (the "Guarantees").
     The Guarantees shall be executed by each of NNG and Litton promptly upon
     the occurrence of the Guarantee Event.

          (16) The following definitions shall be added to Section 101 of the
     Indenture with respect to the Notes:

               "Exchange Offer" shall mean the offer by NNG to purchase, and to
     exchange NNG common and preferred stock for, common and preferred stock of
     Litton pursuant to that certain Registration Statement on Form S-4
     originally filed by NNG on February 1, 2001 with the Commission under the
     Securities Act as it may be amended, supplemented, replaced or superseded.

               "Guarantee Event" shall mean the occurrence of the purchase by
     NNG of Litton common stock in accordance with the Exchange Offer.

               "Litton" shall mean Litton Industries, Inc., a Delaware
     corporation.

               "NNG" shall mean NNG, Inc., a Delaware corporation, to be renamed
     Northrop Grumman Corporation immediately prior to the Guarantee Event.

          (17) Article Thirteen of the Indenture shall be applicable to the
     Notes and in the event of the satisfaction of the conditions to Defeasance
     and Discharge (Section 1302), the obligations of the Guarantors pursuant to
     the Guarantees shall be discharged, and in the event of Covenant Defeasance
     (Section 1303), the obligations of the Guarantors shall be relieved with
     respect to the obligations of the Company that have been released (but not
     the provisions of Section 501(7)).

                                      -7-
<PAGE>

          (18) Each Guarantee shall be subject to amendment by agreement of the
     Guarantor and the Trustee in the manner provided in Article Nine of the
     Indenture. Section 902 of the Indenture is hereby amended to add a new
     subsection (4) as follows with respect to the Notes:

               "(4) modify the obligations of a Guarantor under its Guarantee in
               a manner adverse to the interests of the Holders of the
               Securities."

                      II.    7-3/4 % Debentures due 2031

          (1)  The title of the Securities of the series is "7-3/4% Series A
     Debentures due 2031" (the "Series A Debentures") and "7-3/4% Series B
     Debentures due 2031" (the "Series B Debentures" and, together with the
     Series A Debentures, the "Debentures").

          (2)  The aggregate principal amount of the Debentures which initially
     may be authenticated and delivered under the Indenture (except for
     Debentures authenticated and delivered upon registration of transfer of, or
     in exchange for, or in lieu of, other Debentures of the series pursuant to
     Sections 304, 305, 306, 906 or 1107 of the Indenture and except for any
     Securities which, pursuant to Section 303 of the Indenture, are deemed
     never to have been authenticated and delivered hereunder) is $750,000,000.
     The Company may, without the consent of the holders of the Debentures,
     issue additional debentures having the same ranking, interest rate,
     maturity, CUSIP number and other terms as the Debentures. Any additional
     debentures having such similar terms, together with the Debentures, would
     constitute a single series of Debentures under the Indenture. No additional
     debentures may be issued if an Event of Default has occurred and is
     continuing with respect to the Debentures.

          (3)  Interest on the Debentures shall be payable to the persons in
     whose names the Debentures are registered at the close of business on the
     Regular Record Date (as specified in paragraph II(5) below) for such
     interest payment.

          (4)  The principal of the Debentures shall be payable, unless
     accelerated or earlier redeemed or repurchased pursuant to the Indenture,
     on February 15, 2031.

          (5)  The rate at which each of the Debentures shall bear interest
     shall be 7-3/4% per annum; provided, that in the event of a Non-
                                --------
     Registration Event (as defined in the Registration Rights Agreement) with
     respect to the Debentures, additional interest will accrue on the
     Debentures at an annual rate of.25% for the first 90-day period
     immediately following the occurrence of a Non-Registration Event, and such
     annual rate will increase by an additional.25% with respect to each
     subsequent 90-day period until all Non-Registration Events have been cured,

                                      -8-
<PAGE>

     up to a maximum additional annual interest rate of 1.0%. The additional
     interest will accrue from and including the date on which any such Non-
     Registration Event shall occur to but excluding the date on which all such
     Non-Registration Events have been cured. The Company will pay such
     additional interest on each Interest Payment Date. Such additional interest
     will be in addition to any other interest payable from time to time with
     respect to the Debentures. Interest on the Debentures shall be computed on
     the basis of a 360-day year of twelve 30-day months. The date from which
     interest shall accrue for each of the Debentures shall be February 27,
     2001. The Interest Payment Dates on which interest on the Debentures shall
     be payable are February 15 and August 15, commencing August 15, 2001. The
     Regular Record Date for the interest payable on the Debentures on any
     Interest Payment Date shall be the February 1 or August 1 (whether or not a
     Business Day), as the case may be, next preceding such Interest Payment
     Date.

          (6)  The principal of and interest on the Debentures shall be payable
     in immediately available funds at the office or agency of the Company
     maintained for that purpose in the Institutional Trust Services, Borough of
     Manhattan, the City of New York (as of the date of this Officers'
     Certificate, such office being located at the office of the Trustee, 450
     West 33rd Street, 15th Floor, New York, New York 10001, Attention:
     Institutional Trust Services), in such coin or currency of the United
     States of America as at the time of payment is legal tender for payment of
     public and private debts, provided, however, that at the option of the
     Company payment of interest may be made by wire transfer in immediately
     available funds to an account maintained by the person entitled thereto as
     specified in the Security Register.

          (7)  Northrop Grumman may redeem all or part of the Debentures at any
     time at its option at a redemption price equal to the greater of (a) the
     principal amount of the Debentures being redeemed plus accrued and unpaid
     interest to the redemption date or (b) the Make-Whole Amount for the
     Debentures being redeemed.

     As used in this Section II(7):

               "Adjusted Treasury Rate" means, with respect to any Redemption
     Date, (i) the yield, under the heading which represents the average for the
     immediately preceding week, appearing in the most recently published
     statistical release designed "H.15 (519)" or any successor publication
     which is published weekly by the Board of Governors of the Federal Reserve
     System and which establishes yields on actively traded United States
     Treasury securities adjusted to constant maturity under the caption
     "Treasury Constant Maturities," for the maturity corresponding to the
     Comparable Treasury Issue (if no maturity is within three months before or
     after the remaining term of the Debentures being

                                      -9-
<PAGE>

     redeemed, yields for the two published maturities most closely
     corresponding to the Comparable Treasury Issue shall be determined and the
     Adjusted Treasury Rate shall be interpolated or extrapolated from such
     yields on a straight line basis, rounding to the nearest month) or (ii) if
     such release (or any successor release) is not published during the week
     preceding the calculation date or does not contain such yields, the rate
     per year equal to the semi-annual equivalent yield to maturity of the
     Comparable Treasury Issue (expressed as a percentage of its principal
     amount) equal to the Comparable Treasury Price for such Redemption Date, in
     each case calculated on the third Business Day preceding the Redemption
     Date, plus .30%.

          "Comparable Treasury Issue" means the United States Treasury security
     selected by the Quotation Agent as having a maturity comparable to the
     remaining term from the Redemption Date to the Stated Maturity of the
     principal amount of the Debentures being redeemed that would be utilized,
     at the time of selection and in accordance with customary financial
     practice, in pricing new issues of corporate debt securities of comparable
     maturity to the remaining term of the Debentures being redeemed.

          "Comparable Treasury Price" means, with respect to any Redemption
     Date, if clause (ii) of the Adjusted Treasury Rate is applicable, the
     average of three, or such lesser number as is obtained by the Trustee,
     Reference Treasury Dealer Quotations for such Redemption Date.

          "Make Whole Amount" means the sum, as determined by a Quotation Agent,
     of the present values of the principal amount of the Debentures to be
     redeemed, together with scheduled payments of interest (exclusive of
     interest to the Redemption Rate) from the Redemption Date to the Stated
     Maturity of the principal amount of the Debentures being redeemed, in each
     case discounted to the Redemption Date on a semi-annual basis, assuming a
     360-day year consisting of twelve 30-day months, at the Adjusted Treasury
     Rate, plus accrued and unpaid interest on the principal amount of the
     Debentures being redeemed to the Redemption Date.

          "Quotation Agent" means the Reference Treasury Dealer selected by the
     Trustee after consultation with the Company.

          "Reference Treasury Dealer" means any of the Chase Securities Inc. and
     Credit Suisse First Boston Corporation, and their respective successors and
     assigns, and one other nationally recognized investment banking firm
     selected by the Company that is a primary U.S. Government securities
     dealer.

          "Reference Treasury Dealer Quotations" means, with respect to each
     Reference Treasury Dealer and any Redemption Date, the average, as
     determined

                                      -10-
<PAGE>

     by the Trustee, of the bid and asked prices for the Comparable
     Treasury Issue, expressed in each case as a percentage of its principal
     amount, quoted in writing to the Trustee by such Reference Treasury Dealer
     at 5:00 p.m., New York City time, on the third Business day preceding such
     Redemption Date.

          (8)  There is no obligation of the Company to redeem or purchase the
     Debentures pursuant to any sinking fund or analogous provisions or to
     redeem or purchase any of the Debentures prior to the Stated Maturity at
     the option of the Holder thereof.

          (9)  There is no provision for the conversion or exchange of the
     Debentures, either at the option of the Holder thereof or the Company, into
     or for another security or securities of the Company.

          (10) The Debentures shall be issued only in fully registered form
     without coupons in denominations of $1,000 and integral multiples thereof.

          (11) The entire principal amount of the Debentures shall be payable
     upon declaration of acceleration of the maturity thereof pursuant to
     Section 502 of the Indenture.

          (12) Except as provided in subparagraph (13) below, the Debentures
     shall be issued in the form of one or more Global Securities, in accordance
     with and subject to the provisions of Section 305 of the Indenture and as
     follows (all references in this Section II to Global Securities shall be
     with respect to the Debentures):

                (a)  Debentures sold within the United States to qualified
     institutional buyers, as defined under Rule 144A under the Securities Act
     of 1933, as amended (the "Securities Act"), initially will be represented
     by one or more Global Securities (the "144A Global Debentures"), and
     Debentures sold outside of the United States in reliance on Regulation S
     under the Securities Act initially will be represented by one or more
     Global Securities (the "Regulation S Global Debentures" and, together with
     the 144A Global Debentures, the "Global Debentures"). The Global Debentures
     will be deposited upon issuance with the Trustee as custodian for The
     Depository Trust Company (the "DTC") and registered in the name of DTC or
     its nominee, in each case for credit to an account of a direct or indirect
     participant in DTC.

                (b)  Through and including the 40th day after the later of the
     commencement of the offering of the Debentures and the closing of the
     offering (such period the "Restricted Period"), beneficial interests in the
     Regulation S Global Debentures may be held only through the Euroclear

                                      -11-
<PAGE>

     System ("Euroclear") and Clearstream Banking S.A. ("Clearstream") (as
     indirect participants in DTC), unless transferred to a person that takes
     delivery though a 144A Global Debenture in accordance with certain
     certification requirements.

                (c)  Investors in the 144 Global Debentures who are participants
     in DTC's system ("Participants") may hold their interests therein directly
     through DTC. Investors in the 144A Global Debentures who are not
     Participants may hold their interests therein indirectly through
     organizations (including Euroclear and Clearstream) which are Participants
     in such system. Investors in the Regulation S Global Debentures must
     initially hold their interests therein through Euroclear or Clearstream, if
     they are participants in such systems, or indirectly through organizations
     that are participants in such systems. After the expiration of the
     Restricted Period (but not earlier), investors may also hold interests in
     the Regulation S Global Debentures through Participants in the DTC system
     other than Euroclear and Clearstream. Euroclear and Clearstream will hold
     interests in the Regulation S Global Debentures on behalf of their
     participants through customers' security accounts in their respective names
     on the books of their respective depositories. All interests in Global
     Debentures, including those held through Euroclear or Clearstream, may be
     subject to the procedures and requirements of DTC. Those interests held
     through Euroclear or Clearstream may also be subject to the procedures and
     requirements of such systems.

                (d)  Transfers between participants in DTC will be effected in
     accordance with DTC's procedures, and will be settled in same-day funds,
     and transfers between participants in Euroclear and Clearstream will be
     effected in accordance with their respective rules and operating
     procedures.

                (e)  Prior to the expiration of the Restricted Period,
     beneficial interests in Regulation S Global Debentures may be exchanged for
     beneficial interests in 144A Global Debentures only if (a) such exchange
     occurs in connection with a transfer of the Debentures pursuant to Rule
     144A; and (b) the transferor first delivers to the Trustee a written
     certificate in the form attached hereto as Annex I to the effect that the
                                                -------
     Debentures are being transferred to a person (i) who the transferor
     reasonably believes to be a QIB; (ii) purchasing for its own account or the
     account of a QIB in a transaction meeting the requirements of Rule 144A;
     and (iii) in accordance with all applicable securities laws of the states
     of the United States and other jurisdictions.

                                      -12-
<PAGE>

                (f)  Beneficial interests in 144A Global Debentures may be
     transferred to a person who takes delivery in the form of an interest in
     Regulation S Global Debentures, whether before or after the expiration of
     the Restricted Period, only if the transferor first delivers to the Trustee
     a written certificate in the form attached hereto as Annex I to the effect
                                                          -------
     that such transfer is being made in accordance with Rule 903 or 904 of
     Regulation S or Rule 144 (if available) and that, if such transfer occurs
     prior to the expiration of the Restricted Period, the interest transferred
     will be held immediately thereafter through Euroclear or Clearstream.

                (g)  In addition to the circumstances set forth in clause (2) of
     Section 305 of the Indenture with respect to the exchange of Global
     Debentures for Debentures registered in definitive form, Debentures issued
     as Global Debentures may be exchanged in whole or in part for registered
     Debentures if the Company in its discretion at any time determines not to
     have all the Debentures represented by Global Debentures; and provided,
                                                                   --------
     that clause (B) of clause (2) of Section 305 of the Indenture shall apply
     only if the Event of Default referred to therein has occurred and is
     continuing and entitles the Holders to accelerate the maturity of the
     Debentures. Subject to the foregoing and to paragraph II(13) hereof, the
     Global Debentures are not exchangeable, except for a Global Debenture or
     Global Debentures of the same aggregate denomination to be registered in
     the name of DTC or its nominee.

          (13) Subject to the provisions of paragraph II(12) above, Debentures
     that are (i) originally issued to or transferred to an institutional
     "accredited investor" as defined in Rule 501(a)(1), (2), (3) or (7) under
     the Securities Act who is not a QIB or (ii) issued as certificated
     securities pursuant to the Indenture will be issued in definitive form.
     Upon the transfer to a QIB of a Debenture in definitive form, such
     Debenture will, unless the Global Debenture in respect of such Debenture
     has previously been exchanged for Debentures in definitive form, be
     exchanged for an interest in the Global Debenture representing the
     principal amount of the Debenture being transferred.

          (14) There shall be added to Section 501 of the Indenture the
     following additional Events of Default with respect to the Debentures:

                "(8) The failure of a Guarantor to promptly execute its
                     guaranty of the Debentures upon the occurrence of the

               THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A
               TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES
               SECURITIES ACT OF 1933 (THE "SECURITIES ACT"), AND THIS SECURITY
               MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE

               OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO
               IN (A) ABOVE.

               REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER
               INFORMATION AS IT MAY REASONABLY REQUIRE TO CONFIRM THAT THE
               TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

               TRANSFER OF THE SECURITIES REPRESENTED HEREBY SHALL BE EVIDENCED
               EXCLUSIVELY BY ENDORSEMENT OF THE TRANSFEROR OF THIS CERTIFICATE.

          In addition, Notes and Debentures issued in the name of DTC's nominee
     shall bear the following legend:

               is made to Cede & Co. or to such other entity as is requested by
               an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR
               OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
               WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has

          C.  Any proposed transfer of the Notes or the Debentures, or any
interest therein, shall be subject to the delivery to the Trustee by the

the Trustee may reasonably require.

subject to the transfer restrictions set forth in the Indenture. The Holders of
the Notes shall vote and consent together on all matters as one class and the
Holders of the Debentures shall vote and consent together on all matters as one

               FORM OF CERTIFICATE TO BE DELIVERED UPON EXCHANGE
                   OR REGISTRATION OF TRANSFER OF SECURITIES

          This Certificate relates to $____________ principal amount of
[designate Securities] held in __________ book entry or * __________ definitive
form by ______________ (the "Transferor") and issued under that certain
Indenture dated as of October 15, 1994 (the "Indenture") between Northrop
Grumman Corporation and The Chase Manhattan Bank, as Trustee (the "Trustee").

The Transferor*:

[_]      has requested the Trustee by written order to deliver in exchange for
         its beneficial interest in the Global Security held by the Depository a
         Security or Securities in definitive, registered form of authorized
         denominations in an aggregate principal amount equal to its beneficial
         interest in such Global Security (or the portion thereof indicated
         above); or

[_]      has requested the Trustee by written order to exchange or register the
         transfer of a Security or Securities.

In connection with such request and in respect of each such Security, the
Transferor does hereby certify that the Transferor is familiar with the
Indenture relating to the above captioned Securities and the transfer of this
Security does not require registration under the Securities Act of 1933, as
amended (the "Securities Act") because:*

[_]      Such Security is being acquired for the Transferor's own account,
         without transfer; or

[_]      Such Security is being transferred to a "qualified institutional buyer"
         (as defined in Rule 144A under the Securities Act) in reliance on Rule
         144A; or

[_]      Such Security is being transferred pursuant to an exemption from
         registration in accordance with Rule 903 or Rule 904 under the
         Securities Act; or

                                      -1-

[_]      Such Security is not a "restricted security" as defined under Rule 144
         under the Securities Act.

          NOW, THEREFORE, in consideration of the foregoing, the Guarantor
hereby agrees as follows:

          SECTION 1.  Guarantee; Limitation of Liability.
                      ----------------------------------

          (a) The Guarantor irrevocably and unconditionally guarantees as a
primary obligor and not merely as a surety, to the Trustee and to each Holder of
a Security authenticated and delivered by the Trustee the due and punctual
payment of the principal of and any premium and interest on such Security
(including, in case of default, interest on overdue principal and interest) and
including any additional interest required to be paid according to the terms of
the Securities or the Indenture, when due, whether at stated maturity, upon
redemption or repayment, upon declaration of acceleration or otherwise according
to the terms of the Securities or the Indenture and the due and punctual
performance of all other obligations of the Company to such Holder or the
Trustee, all in accordance with the terms of the Securities and the Indenture
(such obligations being the "Guaranteed Obligations"), and agrees to pay any and
                             ----------------------
all expenses (including reasonable counsel fees and expenses) incurred by such
Holder or the Trustee in enforcing any rights under this Guarantee.  Without
limiting the generality of the foregoing, the Guarantor's liability shall extend
to all amounts that constitute part of the Guaranteed Obligations and would be
owed by the Company to such Holder or the Trustee under the Securities or the
Indenture but for the fact that they are unenforceable or not allowable due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Company because it is the intention of the Guarantor, the Trustee and the
Holders that the Guaranteed Obligations should be determined without regard to
any rule of law or order that might relieve the Company of any portion of the
Guaranteed Obligations.

          (b) Notwithstanding anything to the contrary in this Agreement, the
Guarantor hereby, and the Trustee and each Holder by accepting the benefits of
this Guarantee, confirms that it is its intention that the guarantee by the
Guarantor pursuant to this Guarantee together with each other guarantee by such
Guarantor of Participating Indebtedness (as defined below) shall not constitute
a fraudulent transfer or conveyance for purposes of any applicable provisions of
Title 11 of the United States Code, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act, or any similar federal or state law.  To
effectuate the foregoing intention, the obligations of the Guarantor under this
Guarantee and each other guarantee of Participating Indebtedness shall be
limited, collectively, to such maximum amount as will, after giving effect to
such maximum amount and all other liabilities of such Guarantor, contingent or
otherwise, that are relevant under such laws, and after giving effect to any
rights to subrogation, reimbursement, indemnification or contribution of such
Guarantor pursuant to applicable law or pursuant to any agreement, result in the
obligations of such Guarantor in respect of such maximum amount not constituting
a fraudulent transfer or conveyance.  The Trustee and each Holder by accepting
the

                                      A-2
<PAGE>

benefits of this Guarantee confirms its intention that, in the event of a
bankruptcy, reorganization or other similar proceeding of the Guarantor in which
concurrent claims are made upon such Guarantor hereunder and under any other
guarantee of Participating Indebtedness, to the extent such claims will not be
fully satisfied, each such claimant with a valid claim against the Guarantor
shall be entitled to a ratable share of all payments by such Guarantor in
respect of such concurrent claims.  For purposes of this Section l(b),
"Participating Indebtedness" means any Indebtedness (as defined below) of the
Company that is guaranteed by such Guarantor pursuant to a guarantee (i) the
incurrence of which is not prohibited by the terms of the Indenture or any
agreement governing any other Participating Indebtedness then outstanding (or,
if so prohibited by the Indenture or any such agreement, is permitted as a
result of a consent or waiver thereunder) and (ii) that contains a limitation of
liability and confirmation of intention regarding ratability of payments on
substantially the terms set forth in this Section l(b).  "Indebtedness" means
any indebtedness, whether or not contingent, in respect of borrowed money or
evidenced by bonds, notes, debentures or similar instruments or letters of
credit and, to the extent not otherwise included, the guarantee by the Company
of any indebtedness of any other Person.

          (c) Anything contained herein to the contrary notwithstanding, the
liability of the Company in respect of the Securities guaranteed by the
Guarantor hereunder shall not be limited by the terms of Section l(b).

          SECTION 2.  Guarantee Absolute.  The Guarantor guarantees that the
                      ------------------
Guaranteed Obligations will be paid or performed strictly in accordance with the
terms of the Securities and the Indenture, regardless of any law, regulation or
order now or hereafter in effect in any jurisdiction affecting any of such terms
or the rights of any Holder with respect thereto.  The obligations of the
Guarantor under this Guarantee are independent of the Guaranteed Obligations,
and a separate action or actions may be brought and prosecuted against such
Guarantor to enforce this Guarantee, irrespective of whether any action is
brought against the Company or whether the Company is joined in any such action
or actions.  The liability of the Guarantor under this Guarantee shall be
absolute and unconditional irrespective of:

          (a) any lack of validity or enforceability of the Securities or the
     Indenture or any agreement or instrument relating to the Securities or the
     Indenture or any failure to enforce the provisions thereof;

          (b) any renewal, extension or other change in the time, manner or
     place of payment or performance of, or in any other term of, all or any of
     the Guaranteed Obligations, or any other amendment or waiver of or any
     consent to the departure from the Securities or the Indenture;

          (c) any settlement, compromise, release or discharge, or acceptance or
     refusal of any offer of performance with respect to, or any substitution
     for,

                                      A-3
<PAGE>

     the Guaranteed Obligations or any agreement related thereto and/or any
     subordination of the payment of the same to the payment of any other
     obligations;

          (d) any taking, exchange, release or non-perfection of any mortgage,
     lien, pledge, charge, security interest or encumbrance of any kind, whether
     or not filed, recorded or otherwise perfected under applicable law (each a
     "Lien"), in any real or personal property to secure payment or performance
      ----
     of any or all of the Guaranteed Obligations (whether now or hereafter
     granted, the "Collateral"), or any taking, release, amendment, waiver of,
                   ----------
     or consent to the departure from, any other guarantee, for all or any of
     the Guaranteed Obligations;

          (e) any manner of application of Collateral, or proceeds thereof, to
     all or any of the Guaranteed Obligations, or any manner of sale or other
     disposition of any Collateral or any other assets of the Company or any
     Subsidiary;

          (f) any change, restructuring or termination of the corporate
     structure or existence of the Company or any Subsidiary; or

          (g) any other circumstance (including, without limitation, any statute
     of limitations) that might otherwise constitute a defense available to, or
     a discharge of, the Company or the Guarantor of the Guaranteed Obligations.

          This Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the Guaranteed Obligations is
rescinded or must otherwise be returned by any Holder or the Trustee upon the
insolvency, bankruptcy or reorganization of the Company or for any other reason,
all as though such payment had not been made.  The Guarantor further agrees, to
the fullest extent that it may lawfully do so, that, as between such Guarantor
on the one hand, and the Holders and the Trustee, on the other hand, (i) the
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article Five of the Indenture for the purposes of this Guarantee,

payable by the Guarantor for the purpose of this Guarantee.  In addition,
without limiting the foregoing provision, upon effectiveness of an acceleration
under Article Five of the Indenture, the Trustee shall promptly make a demand

facility, the Guarantor shall cause such Material Subsidiary to execute a
guarantee substantially similar to this Guarantee to guarantee the obligations
of the Company under the Securities, except that the Guarantor shall not be so
obligated to the extent that any such Material Subsidiary guarantee would not be
permitted pursuant to the terms of the Indenture.  The term "Material
                                                             --------

          SECTION 12.  Registration Rights Agreement.  The Guarantor hereby
                       -----------------------------
agrees to become a party to the Registration Rights Agreement on the date hereof
and to comply with the Registration Rights Agreement that are applicable to the
Company with respect to the Securities as they relate to its Guarantee.

          NOW, THEREFORE, in consideration of the foregoing, the Guarantor
hereby agrees as follows:

          SECTION 1.  Guarantee; Limitation of Liability.
                      ----------------------------------

          (a) The Guarantor irrevocably and unconditionally guarantees as a
primary obligor and not merely as a surety, to the Trustee and to each Holder of
a Security authenticated and delivered by the Trustee the due and punctual
payment of the principal of and any premium and interest on such Security
(including, in case of default, interest on overdue principal and interest) and
including any additional interest required to be paid according to the terms of
the Securities or the Indenture, when due, whether at stated maturity, upon
redemption or repayment, upon declaration of acceleration or otherwise according
to the terms of the Securities or the Indenture and the due and punctual
performance of all other obligations of the Company to such Holder or the
Trustee, all in accordance with the terms of the Securities and the Indenture
(such obligations being the "Guaranteed Obligations"), and agrees to pay any and
                             ----------------------
all expenses (including reasonable counsel fees and expenses) incurred by such
Holder or the Trustee in enforcing any rights under this Guarantee.  Without
limiting the generality of the foregoing, the Guarantor's liability shall extend
to all amounts that constitute part of the Guaranteed Obligations and would be
owed by the Company to such Holder or the Trustee under the Securities or the
Indenture but for the fact that they are unenforceable or not allowable due to
the existence of a bankruptcy, reorganization or similar proceeding involving
the Company because it is the intention of the Guarantor, the Trustee and the
Holders that the Guaranteed Obligations should be determined without regard to
any rule of law or order that might relieve the Company of any portion of the
Guaranteed Obligations.

          (b) Notwithstanding anything to the contrary in this Agreement, the
Guarantor hereby, and the Trustee and each Holder by accepting the benefits of
this Guarantee, confirms that it is its intention that the guarantee by the
Guarantor pursuant to this Guarantee together with each other guarantee by such
Guarantor of Participating Indebtedness (as defined below) shall not constitute
a fraudulent transfer or conveyance for purposes of any applicable provisions of
Title 11 of the United States Code, the Uniform Fraudulent Conveyance Act, the
Uniform Fraudulent Transfer Act, or any similar federal or state law.  To
effectuate the foregoing intention, the obligations of the Guarantor under this
Guarantee and each other guarantee of Participating Indebtedness shall be
limited, collectively, to such maximum amount as will, after giving effect to
such maximum amount and all other liabilities of such Guarantor, contingent or
otherwise, that are relevant under such laws, and after giving effect to any
rights to subrogation, reimbursement, indemnification or contribution of such
Guarantor pursuant to applicable law or pursuant to any agreement, result in the
obligations of such Guarantor in respect of such maximum amount not constituting
a fraudulent transfer or conveyance.  The Trustee and each Holder by accepting
the

                                      B-2
<PAGE>

benefits of this Guarantee confirms its intention that, in the event of a
bankruptcy, reorganization or other similar proceeding of the Guarantor in which
concurrent claims are made upon such Guarantor hereunder and under any other
guarantee of Participating Indebtedness, to the extent such claims will not be
fully satisfied, each such claimant with a valid claim against the Guarantor
shall be entitled to a ratable share of all payments by such Guarantor in
respect of such concurrent claims.  For purposes of this Section l(b),
"Participating Indebtedness" means any Indebtedness (as defined below) of the
Company that is guaranteed by such Guarantor pursuant to a guarantee (i) the
incurrence of which is not prohibited by the terms of the Indenture or any
agreement governing any other Participating Indebtedness then outstanding (or,
if so prohibited by the Indenture or any such agreement, is permitted as a
result of a consent or waiver thereunder) and (ii) that contains a limitation of
liability and confirmation of intention regarding ratability of payments on
substantially the terms set forth in this Section l(b).  "Indebtedness" means
any indebtedness, whether or not contingent, in respect of borrowed money or
evidenced by bonds, notes, debentures or similar instruments or letters of
credit and, to the extent not otherwise included, the guarantee by the Company
of any indebtedness of any other Person.

          (c) Anything contained herein to the contrary notwithstanding, the
liability of the Company in respect of the Securities guaranteed by the
Guarantor hereunder shall not be limited by the terms of Section l(b).

          SECTION 2.  Guarantee Absolute.  The Guarantor guarantees that the
                      ------------------
Guaranteed Obligations will be paid or performed strictly in accordance with the
terms of the Securities and the Indenture, regardless of any law, regulation or
order now or hereafter in effect in any jurisdiction affecting any of such terms
or the rights of any Holder with respect thereto.  The obligations of the
Guarantor under this Guarantee are independent of the Guaranteed Obligations,
and a separate action or actions may be brought and prosecuted against such
Guarantor to enforce this Guarantee, irrespective of whether any action is
brought against the Company or whether the Company is joined in any such action
or actions.  The liability of the Guarantor under this Guarantee shall be
absolute and unconditional irrespective of:

          (a) any lack of validity or enforceability of the Securities or the
     Indenture or any agreement or instrument relating to the Securities or the
     Indenture or any failure to enforce the provisions thereof;

          (b) any renewal, extension or other change in the time, manner or
     place of payment or performance of, or in any other term of, all or any of
     the Guaranteed Obligations, or any other amendment or waiver of or any
     consent to the departure from the Securities or the Indenture;

          (c) any settlement, compromise, release or discharge, or acceptance or
     refusal of any offer of performance with respect to, or any substitution
     for,

                                      B-3
<PAGE>

     the Guaranteed Obligations or any agreement related thereto and/or any
     subordination of the payment of the same to the payment of any other
     obligations;

          (d) any taking, exchange, release or non-perfection of any mortgage,
     lien, pledge, charge, security interest or encumbrance of any kind, whether
     or not filed, recorded or otherwise perfected under applicable law (each a
     "Lien"), in any real or personal property to secure payment or performance
      ----
     of any or all of the Guaranteed Obligations (whether now or hereafter
     granted, the "Collateral"), or any taking, release, amendment, waiver of,
                   ----------
     or consent to the departure from, any other guarantee, for all or any of
     the Guaranteed Obligations;

          (e) any manner of application of Collateral, or proceeds thereof, to
     all or any of the Guaranteed Obligations, or any manner of sale or other
     disposition of any Collateral or any other assets of the Company or any
     Subsidiary;

          (f) any change, restructuring or termination of the corporate
     structure or existence of the Company or any Subsidiary; or

          (g) any other circumstance (including, without limitation, any statute
     of limitations) that might otherwise constitute a defense available to, or
     a discharge of, the Company or the Guarantor of the Guaranteed Obligations.

This Guarantee shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by any Holder or the Trustee upon the insolvency,
bankruptcy or reorganization of the Company or for any other reason, all as
though such payment had not been made.  The Guarantor further agrees, to the
fullest extent that it may lawfully do so, that, as between such Guarantor on
the one hand, and the Holders and the Trustee, on the other hand, (i) the
maturity of the obligations guaranteed hereby may be accelerated as provided in
Article Five of the Indenture for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition extant under any
applicable bankruptcy law preventing such acceleration in respect of the
obligations guaranteed hereby and (ii) in the event of any declarations of
acceleration of such obligations as provided in Article Five of the Indenture,
such obligations (whether or not due and payable) shall forthwith become due and
payable by the Guarantor for the purpose of this Guarantee.  In addition,
without limiting the foregoing provision, upon effectiveness of an acceleration
under Article Five of the Indenture, the Trustee shall promptly make a demand
for payment on the Securities under this Guarantee provided for hereunder and
not discharged.

                                      B-4
<PAGE>

          SECTION 3. Waivers.
                     -------

          (a) The Guarantor hereby waives:  (i) promptness, diligence,
presentment, notice of acceptance and any other notice with respect to any of
the Guaranteed Obligations and this Guarantee, (ii) any requirement to file any
claims with a court in the event of merger or bankruptcy of the Company or any
guarantor of the Guaranteed Obligations, (iii) any right to require a proceeding
first against the Company or any other guarantor of the Guaranteed Obligations,
(iv) the benefit of discussion or protest or notice with respect to any such
Securities or the Indebtedness evidenced thereby, (v) any requirement that any
Holder or the Trustee protect, secure, perfect or insure any Lien or any
Collateral subject thereto or exhaust any right or take any action against the
Company or any other Person or any Collateral, (vi) any defense arising by
reason of the incapacity, lack of authority or any disability or other defense
of the Company, (vii) any defense based upon any statute or rule of law which
provides that the obligation of a surety must be neither larger in amount nor in
any other respects more burdensome than that of the principal, (viii) any
defense based upon any errors or omissions of the Trustee or the Holders'
administration of the Guaranteed Obligations, and (ix) any rights to set-offs,
recoupments and counterclaims.

          (b) The Guarantor hereby irrevocably waives all right to trial by jury
in any action, proceeding or counterclaim (whether based on contract, tort or
otherwise) arising out of or relating to any of the Securities or the Indenture,
the transactions contemplated thereby or the actions of the Trustee in the
negotiation, administration, performance or enforcement thereof.

          SECTION 4.  Financial Condition of the Company.  The Guarantor
                      ----------------------------------
represents and warrants that it is presently informed of the financial condition
of the Company and of all other circumstances which a diligent inquiry would
reveal and which bear upon the risk of nonpayment of the Guaranteed Obligations.
The Guarantor hereby covenants that it will continue to keep itself informed of
the Company's financial condition and of all other circumstances which bear upon
the risk of nonpayment and hereby waives any duty on the part of the Trustee or
any Holder to disclose or discuss with such Guarantor its assessment, or such
Guarantor's assessment, of the financial condition of the Company.

          SECTION 5.  Subrogation.  The Guarantor will not exercise any rights
                      -----------
that it may acquire by way of subrogation under this Guarantee, by any payment
made hereunder or otherwise, until all the Guaranteed Obligations shall have
been indefeasibly paid in full in cash.  If any amount shall be paid to the
Guarantor on account of any such subrogation rights at any time when all the
Guaranteed Obligations shall not have been paid in full, such amount shall be

          Northrop Grumman Corporation, a corporation duly organized and
existing under the laws of Delaware (herein called the "Company," which term
includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to __________, or registered assigns, the
principal sum of ________________ Dollars on February 15, 2011 and to pay
interest thereon from February 27, 2001 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, semi-annually on

15 in each year, commencing August 15, 2001 at the rate of 7-1/8% per annum,
until the principal hereof is paid or made available for payment; provided, that
                                                                  --------
in the event of a Non-Registration Event (as defined in the Registration Rights
Agreement dated as of February 27, 2001 by and among the Company and the initial
purchasers identified therein) with respect to the Securities of this series,
additional interest will accrue on such Securities at an annual rate of .25% for
the first 90-day period immediately following the occurrence of a Non-
Registration Event, and such annual rate will increase by an additional .25%
with respect to each subsequent 90-day period until all Non-Registration Events
have been cured, up to a maximum additional annual interest rate of 1.0%. The
additional interest will accrue from and including the date on which any such
Non-Registration Event shall occur to but excluding the date on which all such
Non-Registration Events have been cured. The Company will pay such additional
interest on each Interest Payment Date. Such additional interest will be in
addition to any other interest payable from time to time with respect to the
Securities of this series. Interest shall be computed on the basis of a 360-day
year of twelve 30-day months. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in such
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be the February 1 or August 1
(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

          Payment of the principal of (and premium, if any) and any such
interest on this Security will be made in immediately available funds at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City of New York in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made by wire transfer in immediately available funds to an
account maintained by the person entitled thereto as specified in the Security
Register.

          Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

                             [REVERSE OF SECURITY]

          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of October 15, 1994 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and The Chase Manhattan Bank, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are and are to be authenticated and delivered.  This
Security is one of the series designated on the face hereof.  The Securities are
unsecured general obligations of the Company.

          The Securities of this series are subject to redemption upon not less
than 30 days notice by mail, as a whole or in part, at the election of the
Company at a Redemption Price equal to the greater of (a) the principal amount
of the Securities being redeemed plus accrued and unpaid interest to the
Redemption Date or (2) the Make-Whole Amount for the Securities being redeemed.

          As used in this Security:

               "Adjusted Treasury Rate" means, with respect to any Redemption
     Date, (i) the yield, under the heading which represents the average for the
     immediately preceding week, appearing in the most recently published
     statistical release designated "H.15 (519)" or any successor publication
     which is published weekly by the Board of Governors of the Federal Reserve
     System and which establishes yields on actively traded United States
     Treasury securities adjusted to constant maturity under the caption
     "Treasury Constant Maturities," for the maturity corresponding to the
     Comparable Treasury Issue (if no maturity is within three months before or
     after the remaining term of the Securities being redeemed, yields for the
     two published maturities most closely corresponding to the Comparable
     Treasury Issue shall be determined and the Adjusted Treasury Rate shall be
     interpolated or extrapolated from such yields on a straight line basis,
     rounding to the nearest month) or (ii) if such release (or any successor
     release) is not published during the week preceding the calculation date or
     does not contain such yields, the rate per year equal to the semi-annual
     equivalent yield to maturity of the Comparable Treasury Issue (expressed as
     a percentage of its principal amount) equal to the Comparable Treasury
     Price for such Redemption Date, in each case calculated on the third
     Business Day preceding the Redemption Date, plus .25%.

               "Comparable Treasury Issue" means the United States Treasury
     security selected by the Quotation Agent as having a maturity comparable to
     the

                                      C-6
<PAGE>

     remaining term from the Redemption Date to the Stated Maturity of the
     principal amount of the Securities being redeemed that would be utilized,
     at the time of selection and in accordance with customary financial
     practice, in pricing new issues of corporate debt securities of comparable
     maturity to the remaining term of this Security.

               "Comparable Treasury Price" means, with respect to any Redemption
     Date, if clause (ii) of the Adjusted Treasury Rate is applicable, the
     average of three, or such lesser number as is obtained by the Trustee,
     Reference Treasury Dealer Quotations for such Redemption Date.

               "Make Whole Amount" means the sum, as determined by a Quotation
     Agent, of the present values of the principal amount of the Securities to
     be redeemed, together with scheduled payments of interest (exclusive of
     interest to the Redemption Rate) from the Redemption Date to the Stated
     Maturity of the principal amount of the Securities being redeemed, in each
     case discounted to the Redemption Date on a semi-annual basis, assuming a
     360-day year consisting of twelve 30-day months, at the Adjusted Treasury
     Rate, plus accrued interest on the principal amount of the Securities being
     redeemed to the Redemption Date.

               "Quotation Agent" means the Reference Treasury Dealer selected by
     the Trustee after consultation with the Company.

               "Reference Treasury Dealer" means any of Chase Securities Inc.
     and Credit Suisse First Boston Corporation, and their respective successors
     and assigns, and one other nationally recognized investment banking firm
     selected by the Company that is a primary U.S. Government securities
     dealer.

               "Reference Treasury Dealer Quotations" means, with respect to
     each Reference Treasury Dealer and any Redemption Date, the average, as
     determined by the Trustee, of the bid and asked prices for the Comparable
     Treasury Issue, expressed in each case as a percentage of its principal
     amount, quoted in writing to the Trustee by such Reference Treasury Dealer
     at 5:00 p.m., New York City time, on the third Business Day preceding such
     Redemption Date.

          In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

          The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security or certain restrictive covenants and Events
of

                                      C-7
<PAGE>

Default with respect to this Security, in each case upon compliance with
certain conditions set forth in the Indenture.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the securities at
the time Outstanding of each series to be affected.  The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

          As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity.  The
foregoing shall not apply to any suit instituted by the Holder of this Security
for the enforcement of any payment of principal hereof or any premium or
interest hereon on or after the respective due dates expressed herein.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

                                      C-8

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

          Northrop Grumman Corporation, a corporation duly organized and
existing under the laws of Delaware (herein called the "Company," which term
includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to __________, or registered assigns, the
principal sum of ________________ Dollars on February 15, 2031 and to pay
interest thereon from February 27, 2001 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, semi-annually on
February 15 and August 15 in each year, commencing August 15, 2001 at the rate
of 7-3/4% per annum, until the principal

hereof is paid or made available for payment; provided, that in the event of a
                                              --------
Non-Registration Event (as defined in the Registration Rights Agreement dated as
of February 27, 2001 by and among the Company and the initial purchasers
identified therein) with respect to the Securities of this series, additional
interest will accrue on such Securities at an annual rate of .25% for the first
90-day period immediately following the occurrence of a Non-Registration Event,
and such annual rate will increase by an additional .25% with respect to each
subsequent 90-day period until all Non-Registration Events have been cured, up
to a maximum additional annual interest rate of 1.0%. The additional interest
will accrue from and including the date on which any such Non-Registration Event
shall occur to but excluding the date on which all such Non-Registration Events
have been cured. The Company will pay such additional interest on each Interest
Payment Date. Such additional interest will be in addition to any other interest
payable from time to time with respect to the Securities of this series.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be the February 1 or August 1 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

          Payment of the principal of (and premium, if any) and any such
interest on this Security will be made in immediately available funds at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City of New York in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made by wire transfer in immediately available funds to an
account maintained by the person entitled thereto as specified in the Security
Register.

          Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

                             [REVERSE OF SECURITY]

          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of October 15, 1994 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and The Chase Manhattan Bank, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee and the Holders of the Securities and of the terms
upon which the Securities are and are to be authenticated and delivered.  This
Security is one of the series designated on the face hereof.  The Securities are
unsecured general obligations of the Company.

          The Securities of this series are subject to redemption upon not less
than 30 days notice by mail, as a whole or in part, at the election of the
Company at a Redemption Price equal to the greater of (a) the principal amount
of the Securities being redeemed plus accrued and unpaid interest to the
Redemption Date or (2) the Make-Whole Amount for the Securities being redeemed.

          As used in this Security:

               "Adjusted Treasury Rate" means, with respect to any Redemption
     Date, (i) the yield, under the heading which represents the average for the
     immediately preceding week, appearing in the most recently published
     statistical release designated "H.15 (519)" or any successor publication
     which is published weekly by the Board of Governors of the Federal Reserve
     System and which establishes yields on actively traded United States
     Treasury securities adjusted to constant maturity under the caption
     "Treasury Constant Maturities," for the maturity corresponding to the
     Comparable Treasury Issue (if no maturity is within three months before or
     after the remaining term of the Securities being redeemed, yields for the
     two published maturities most closely corresponding to the Comparable
     Treasury Issue shall be determined and the Adjusted Treasury Rate shall be
     interpolated or extrapolated from such yields on a straight line basis,
     rounding to the nearest month) or (ii) if such release (or any successor
     release) is not published during the week preceding the calculation date or
     does not contain such yields, the rate per year equal to the semi-annual
     equivalent yield to maturity of the Comparable Treasury Issue (expressed as
     a percentage of its principal amount) equal to the Comparable Treasury
     Price for such Redemption Date, in each case calculated on the third
     Business Day preceding the Redemption Date, plus .30%.

                                      D-6
<PAGE>

               "Comparable Treasury Issue" means the United States Treasury
     security selected by the Quotation Agent as having a maturity comparable to
     the remaining term from the Redemption Date to the Stated Maturity of the
     principal amount of the Securities being redeemed that would be utilized,
     at the time of selection and in accordance with customary financial
     practice, in pricing new issues of corporate debt securities of comparable
     maturity to the remaining term of this Security.

               "Comparable Treasury Price" means, with respect to any Redemption
     Date, if clause (ii) of the Adjusted Treasury Rate is applicable, the
     average of three, or such lesser number as is obtained by the Trustee,
     Reference Treasury Dealer Quotations for such Redemption Date.

               "Make Whole Amount" means the sum, as determined by a Quotation
     Agent, of the present values of the principal amount of the Securities to
     be redeemed, together with scheduled payments of interest (exclusive of
     interest to the Redemption Rate) from the Redemption Date to the Stated
     Maturity of the principal amount of the Securities being redeemed, in each
     case discounted to the Redemption Date on a semi-annual basis, assuming a
     360-day year consisting of twelve 30-day months, at the Adjusted Treasury
     Rate, plus accrued interest on the principal amount of the Securities being
     redeemed to the Redemption Date.

               "Quotation Agent" means the Reference Treasury Dealer selected by
     the Trustee after consultation with the Company.

               "Reference Treasury Dealer" means any of Chase Securities Inc.
     and Credit Suisse First Boston Corporation, and their respective successors
     and assigns, and one other nationally recognized investment banking firm
     selected by the Company that is a primary U.S. Government securities
     dealer.

               "Reference Treasury Dealer Quotations" means, with respect to
     each Reference Treasury Dealer and any Redemption Date, the average, as
     determined by the Trustee, of the bid and asked prices for the Comparable
     Treasury Issue, expressed in each case as a percentage of its principal
     amount, quoted in writing to the Trustee by such Reference Treasury Dealer
     at 5:00 p.m., New York City time, on the third Business Day preceding such
     Redemption Date.

          In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

          The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security or certain restrictive covenants and Events
of Default with

                                      D-7
<PAGE>

respect to this Security, in each case upon compliance with certain conditions
set forth in the Indenture.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the securities at
the time Outstanding of each series to be affected.  The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

          As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity.  The
foregoing shall not apply to any suit instituted by the Holder of this Security
for the enforcement of any payment of principal hereof or any premium or
interest hereon on or after the respective due dates expressed herein.

          No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

                                      D-8
<PAGE>

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

          The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.
