Item 2. Acquisition Or Disposition Of Assets

Northrop Grumman Corporation (formerly NNG, Inc.), a Delaware corporation ("New Northrop Grumman") entered into an Amended and Restated Agreement and Plan of Merger (the "Amended Merger Agreement"), dated January 23, 2001, among New Northrop Grumman, Northrop Grumman Systems Corporation (formerly Northrop Grumman Corporation), a Delaware corporation ("Systems"), Litton Industries, Inc., a Delaware corporation ("Litton") and LII Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of New Northrop Grumman ("LII").

Pursuant to the Amended Merger Agreement, New Northrop Grumman agreed to acquire all of the outstanding capital stock of Litton through an offer to purchase or exchange (the "Offer") followed by a merger (the "Litton Merger") of LII with and into Litton, with Litton as the corporation surviving the Litton Merger as a wholly-owned subsidiary of New Northrop Grumman. Pursuant to the Offer to Purchase or Exchange dated February 1, 2001 and comprising a part of New Northrop Grumman's Registration Statement on Form S-4 (Commission File No. 333-54800) as amended from time to time, New Northrop Grumman offered to purchase (a) each outstanding share of the Litton Common Stock for any of the following, at the election of the holder: (i) $80.00 net per share, in cash, not subject to proration, (ii) 0.9286 shares of common stock of New Northrop Grumman, par value $1.00 per share, subject to proration, or (iii) 0.80 shares of Series B Preferred Stock of New Northrop Grumman, subject to proration, and
(b) each outstanding share of Series B $2 Cumulative Preferred Stock (the "Litton Preferred Stock") of Litton for $35.00 net per share, in cash. Pursuant to the Offer, a maximum of 13,000,000 shares of New Northrop Grumman common stock and 3,500,000 shares of New Northrop Grumman Series B Preferred Stock were issuable in exchange for validly tendered shares of Litton Common Stock.

The Offer expired at Midnight New York City time on Monday, April 2, 2001 and at approximately 12:30 a.m. on April 3, 2001, New Northrop Grumman accepted for purchase or exchange 44,660,440 shares of Litton Common Stock and 240,632 shares of Litton Preferred Stock, which represents approximately 97.3% of the outstanding shares of Litton Common Stock and approximately 58.6% of the outstanding shares of Litton Preferred Stock, respectively, as of March 28, 2001. On April 11, 2001, New Northrop Grumman assigned all of its right, title and interest in the 240,632 shares of Litton Preferred Stock purchased by it pursuant to the Offer to Systems, its wholly-owned subsidiary.

The value of the Litton acquisition is approximately $5.1 billion, which includes the assumption of Litton's approximately $1.3 billion in net debt. The purchase price was based upon an analysis of the perceived value of the ongoing business and the estimated net assets to be acquired and took into account the liabilities reflected on the balance sheet of Litton and assumed by New Northrop Grumman.

New Northrop Grumman obtained the cash portion of the purchase price from
(i) an offering made by Systems pursuant to Rule 144A promulgated under the Securities Act of 1933, as amended, of $1.5 billion in debt securities having maturity dates of 10 and 30 years and (ii) advances pursuant to credit facilities consisting of a $2.5 billion Five Year Revolving Credit Agreement and a $2.5 billion 364-Day Revolving Credit Agreement, each dated

Page 2 of 7

March 30, 2001, among New Northrop Grumman, Systems, Litton, The Chase Manhattan Bank and Credit Suisse First Boston, as Co-Administrative Agents, Solomon Smith Barney Inc., as Syndication Agent, the Bank of Novia Scotia and Deutsche Banc Alex. Brown, Inc., as Co-Documentation Agents, and the lender signatories thereto (each, a "Credit Agreement"). Forms of each Credit Agreement are included as Exhibits 10.6 and 10.7 hereto and reference is made thereto for the complete terms and conditions of each Credit Agreement.

On April 3, 2001, New Northrop Grumman executed and delivered guarantees of the outstanding indenture indebtedness of Litton and Systems, Systems executed and delivered guarantees of the outstanding indenture indebtedness of Litton, and Litton executed and delivered guarantees of the outstanding indenture indebtedness of Systems.

Pursuant to the Amended Merger Agreement, on April 2, 2001, Systems completed a corporate reorganization to create a holding company structure (the "Northrop Reorganization") that was effected by action of its Board of Directors without a vote of System's stockholders pursuant to Section 251(g) of the Delaware General Corporation Law (the "DGCL"). In accordance with Section 251(g) of the DGCL, NGC Acquisition Corp., a Delaware corporation and indirect wholly- owned subsidiary of Systems, was merged with and into Systems, with Systems as the surviving corporation and a wholly-owned subsidiary of New Northrop Grumman, the new holding company. At the effective time of that merger and in connection with the Northrop Reorganization, New Northrop Grumman changed its name from NNG, Inc. to "Northrop Grumman Corporation," and Northrop Grumman Corporation changed its name to "Northrop Grumman Systems Corporation." In the Northrop Reorganization, all of the outstanding shares of capital stock of Systems became the same number of shares of the same class of capital stock of New Northrop Grumman. Outstanding options to acquire common stock of Systems became options to acquire common stock of New Northrop Grumman.

Pursuant to the Amended Merger Agreement, the acquisition of Litton will be completed through a second step merger in which LII will be merged into Litton and the remaining holders of common shares of Litton will receive $80.00 in cash for each common share.

In the normal course of their business, Systems and Litton are parties to transactions and agreements.

Unitrin, Inc., which together with certain of its subsidiaries, collectively owned approximately 27.8% of the outstanding shares of Litton common stock as of January 23, 2001, entered into a Stockholders Agreement dated as of January 23, 2001 with New Northrop Grumman and Systems, pursuant to which Unitrin agreed to tender and cause its subsidiaries and affiliates to tender at least 3,750,000 of their shares of Litton common stock in the offer for shares of New Northrop Grumman preferred stock and to tender the remainder for New Northrop Grumman common stock. In addition, Systems and New Northrop Grumman entered into a Registration Rights Agreement dated as of January 23, 2001 with Unitrin, whereby Systems and New Northrop Grumman agreed to provide certain registration rights to Unitrin with respect to the shares of New Northrop Grumman stock issued in exchange for Unitrin's and its subsidiaries' and affiliates' Litton common stock. The Stockholder's Agreement and the Registration Rights Agreement are included as Exhibits 10.1 and 4.1 hereto, and reference is made thereto for the complete terms and conditions of each agreement.

Pursuant to a letter agreement with Dr. Ronald D. Sugar dated December 21, 2000, as amended on January 31, 2001, Systems and Dr. Sugar agreed that Dr. Sugar will serve as Corporate Vice President of New Northrop Grumman and President and Chief Executive Officer of Litton. The parties also agreed that Dr. Sugar will be nominated to New Northrop Grumman's Board of Directors effective as of the closing of the Litton Merger, provided that the Litton Merger closes on or before December 31, 2001. On April 3, 2001, Dr. Sugar was elected to New Northrop Grumman's Board of Directors. In general, under the terms of the letter agreement, New Northrop Grumman assumed Litton's obligations under Dr. Sugar's change of control employment agreement and his letter agreement dated June 21, 2000.

Except as described above or disclosed in the Offer to Purchase or Exchange, no known material relationship exists between Litton and New Northrop Grumman or any of its affiliates, directors or officers, or any associate of any such directors or officers. The foregoing summary is qualified in its entirety by the exhibits attached hereto, which are incorporated herein by this reference.

EXHIBIT 10.9

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-

(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-

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-

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-

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.

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.

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-

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

(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").

-7-

(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-

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-

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-

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.

(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 Guarantee Event; or

EXHIBIT A

PARENT GUARANTEE

PARENT GUARANTEE dated as of ______________, 2001 (this "Guarantee") made by Northrop Grumman Corporation, a Delaware corporation (formerly NNG, Inc.) ("Guarantor") in favor of and for the benefit of The Chase Manhattan Bank, as trustee (the "Trustee") for the Holders (as such term is defined in the Indenture referred to below) of the 7-1/8% Series A Notes due 2011 (the "Series A Notes") and the 7-1/8% Series B Notes due 2011 (the "Series B Notes" and,
together with the Series A Notes, the "Notes") and the 7-3/4% Series A Debentures due 2031 (the "Series A Debentures") and the 7-3/4% Series B Debentures due 2031 (the "Series B Debentures" and, together with the Series A Debentures, the "Debentures") of Northrop Grumman Operations Corporation, a Delaware corporation (formerly Northrop Grumman Corporation) (the "Company"). The Notes and the Debentures shall be referred to collectively as the "Securities".

WHEREAS, the Company has entered into an Indenture dated as of October 15, 1994 between the Company and the Trustee, as supplemented by that certain Officers' Certificate attached hereto as Exhibit A dated as of February 22, 2001 establishing the Securities (as so supplemented, and as further amended, modified and supplemented from time to time with respect to the Securities, the "Indenture"). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture; and

WHEREAS, the Company offered and sold $750,000,000 aggregate principal amount of Series A Notes and $750,000,000 aggregate principal amount of Series A Debentures in a private placement transaction that closed on February 27, 2001; and

WHEREAS, pursuant to a Registration Rights Agreement entered into on February 27, 2001 by and among the Company and the other parties thereto (the "Registration Rights Agreement"), the Company has agreed to certain terms in connection with the registration of the Series B Notes and the Series B Debentures; and

WHEREAS, the Company and its affiliates (including, without limitation, the Guarantor) derive, and expect to continue to derive, substantial direct and indirect benefit from the transactions financed by the issuance and sale of the Securities; and

WHEREAS, the Indenture provides that the Guarantor shall execute and deliver this Guarantee upon the occurrence of the Guarantee Event (as defined therein).

A-1

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

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;

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) 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.

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.

A-5

behalf of the Holders, to be credited and applied to the Guaranteed Obligations, whether matured or unmatured.

SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guarantee and no consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee, on behalf of the Holders, pursuant to the provisions of Article Nine of the Indenture, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and delivered in person or mailed by first-class mail, if to the Guarantor, addressed to it at the address of the Company at 1840 Century Park East, Los Angeles, California 90067, Attention:

All such notices and other communications shall, when mailed by first class mail, be effective when deposited in the first class mails.

SECTION 8. No Waiver; Remedies.

Except with the consent of the holders of Securities as provided in the Indenture, the Guarantor may not consolidate with or merge into another entity, or convey, transfer or lease its properties and assets substantially as an entirety to any Person unless:

LITTON GUARANTEE

LITTON GUARANTEE dated as of __________, 2001 (this "Guarantee") made by Litton Industries, Inc., a Delaware corporation ("Guarantor") in favor of and for the benefit of The Chase Manhattan Bank, as trustee (the "Trustee") for the Holders (as such term is defined in the Indenture referred to below) of the 7- 1/8% Series A Notes due 2011 (the "Series A Notes") and the 7-1/8% Series B Notes due 2011 (the "Series B Notes" and, together with the Series A Notes, the "Notes") and the 7-3/4% Series A Debentures due 2031 (the "Series A Debentures")
and the 7-3/4% Series B Debentures due 2031 (the "Series B Debentures" and, together with the Series A Debentures, the "Debentures") of Northrop Grumman Operations Corporation, a Delaware corporation (formerly Northrop Grumman Corporation) (the "Company"). The Notes and the Debentures shall be referred to collectively as the "Securities".

WHEREAS, the Company has entered into an Indenture dated as of October 15, 1994 between the Company and the Trustee, as supplemented by that certain Officers' Certificate attached hereto as Exhibit A dated as of February 22, 2001 establishing the Securities (as so supplemented, and as further amended, modified and supplemented from time to time with respect to the Securities, the "Indenture"). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture; and

WHEREAS, the Company offered and sold $750,000,000 aggregate principal amount of Series A Notes and $750,000,000 aggregate principal amount of Series A Debentures in a private placement transaction that closed on February 27, 2001; and

WHEREAS, pursuant to a Registration Rights Agreement entered into on February 27, 2001 by and among the Company and the other parties thereto (the "Registration Rights Agreement"), the Company has agreed to certain terms in connection with the registration of the Series B Notes and the Series B Debentures; and

WHEREAS, the Company and its affiliates (including, without limitation, the Guarantor) derive, and expect to continue to derive, substantial direct and indirect benefit from the transactions financed by the issuance and sale of the Securities; and

WHEREAS, the Indenture provides that the Guarantor shall execute and delivery this Guarantee upon the occurrence of the Guarantee Event (as defined therein).

B-1

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

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

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

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.

B-5

behalf of the Holders, to be credited and applied to the Guaranteed Obligations, whether matured or unmatured.

SECTION 6. Amendments, Etc.

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.

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

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

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.

GUARANTEE
(NGC of Litton 1991 Indenture Debt)

GUARANTEE dated as of April 3, 2001 (this "Guarantee") made by Northrop Grumman Corporation, a Delaware corporation (formerly NNG, Inc.) ("Guarantor"), in favor of and for the benefit of The Bank of New York, as trustee (the "Trustee") for the Holders (as such term is defined in the Indenture referred to below) of the 7.75% Debentures due 2026 and the 6.98% Debentures due 2036 (collectively, the "Securities") of Litton Industries, Inc. (the "Company").

WHEREAS, the Company has entered into a Senior Indenture dated as of December 15, 1991 between the Company and the Trustee (as amended, modified and supplemented from time to time with respect to the Securities, the "Indenture"). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture; and

WHEREAS, the Company is a subsidiary of the Guarantor.

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

-1-

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 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

-2-

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, 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.

-3-

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.

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.

-4-

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 held in trust for the benefit of the Holders and the Trustee and shall forthwith be paid to the Trustee, on behalf of the Holders, to be credited and applied to the Guaranteed Obligations, whether matured or unmatured.

SECTION 6. Amendments, Etc. No amendment or waiver of any provisio of this Guarantee and no consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee, on behalf of the Holders, pursuant to the provisions of Article Nine of the Indenture, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and delivered in person or mailed by first-class mail, if to the Guarantor, addressed to it at the address of the Company at 1840 Century Park East, Los Angeles, California 90067, Attention:

EXHIBIT 10.11
GUARANTEE
(NGC of NGSC Outstanding Indenture Debt)

GUARANTEE dated as of April 3, 2001 (this "Guarantee") made by Northrop Grumman Corporation, a Delaware corporation (formerly NNG, Inc.)

("Guarantor"), in favor of and for the benefit of The Chase Manhattan Bank, as trustee (the "Trustee") for the Holders (as such term is defined in the Indenture referred to below) of the 8.625% Notes due 2004, the 9.735% Debentures due 2024, the 7% Notes due 2006, the 7.75% Debentures due 2016 and the 7.875% Debentures due 2026 (collectively, the "Securities") of Northrop Grumman Systems Corporation (formerly Northrop Grumman Corporation) (the "Company").

WHEREAS, the Company has entered into an Indenture dated as of October 15, 1994 between the Company and the Trustee (as amended, modified and supplemented from time to time with respect to the Securities, the "Indenture"). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture; and

WHEREAS, the Company is a wholly-owned subsidiary of the Guarantor.

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

-1-

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 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).

-2-

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, 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

-3-

(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.

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.

-4-

(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 held in trust for the benefit of the Holders and the Trustee and shall forthwith be paid to the Trustee, on behalf of the Holders, to be credited and applied to the Guaranteed Obligations, whether matured or unmatured.

SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guarantee and no consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee, on behalf of the Holders, pursuant to the provisions of Article Nine of the Indenture, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and delivered in person or mailed by first-class mail, if to the Guarantor, addressed to it at the address of the Company at 1840 Century Park East, Los Angeles, California 90067, Attention:

GUARANTEE
(NGSC of Litton 1991 Indenture Debt)

GUARANTEE dated as of April 3, 2001 (this "Guarantee") made by Northrop Grumman Systems Corporation, a Delaware corporation (formerly Northrop Grumman Corporation) ("Guarantor"), in favor of and for the benefit of The Bank of New York, as trustee (the "Trustee") for the Holders (as such term is defined in the Indenture referred to below) of the 7.75% Debentures due 2026 and the 6.98% Debentures due 2036 (collectively, the "Securities") of Litton Industries, Inc. (the "Company").

WHEREAS, the Company has entered into a Senior Indenture dated as of December 15, 1991 between the Company and the Trustee (as amended, modified and supplemented from time to time with respect to the Securities, the "Indenture"). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture; and

WHEREAS, the Guarantor and the Company are both subsidiaries of Northrop Grumman Corporation (formerly NNG, Inc.); and

WHEREAS, in consideration for the guarantee of the Securities by the Guarantor, the Company has agreed to guarantee certain outstanding indenture debt of the Guarantor.

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

-1-

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 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).

(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, 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;

-3-

(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.

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

-4-

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 held in trust for the benefit of the Holders and the Trustee and shall forthwith be paid to the Trustee, on behalf of the Holders, to be credited and applied to the Guaranteed Obligations, whether matured or unmatured.

SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guarantee and no consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee, on behalf of the Holders, pursuant to the provisions of Article Nine of the Indenture, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and delivered in person or mailed by first-class mail, if to the Guarantor, addressed to it at the address of the Company at 1840 Century Park East, Los Angeles, California 90067, Attention:

shall be designated by such party in a written notice to each other party. All such notices and other communications shall, when mailed by first class mail, be effective when deposited in the first class mails.

SECTION 8. No Waiver; Remedies. No failure on the part of any Holder or the Trustee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 9. Continuing Guarantee. This Guarantee is a continuing guarantee and shall (a) remain in full force and effect until the earlier of the payment in full (including deemed payment pursuant to Section 403 of the Indenture) of the Guaranteed Obligations and all other amounts payable under this Guarantee, and the termination of this Guarantee pursuant to Section 10 of this Guarantee, (b) subject to the terms hereof, be binding upon the Guarantor, its respective successors and assigns and (c) inure to the benefit of and be enforceable by each Holder and the Trustee and their respective successors, transferees and assigns.

SECTION 10. Guarantor May Consolidate, Etc., on Certain Terms. Except with the consent of the Holders of Securities as provided in the Indenture, the Guarantor may not consolidate with or merge into any other Person or transfer (by lease, assignment, sale or otherwise) all or substantially all its properties and assets to another Person or group of affiliated Persons, unless:

(a) any successor entity is a corporation, partnership or trust organized and validly existing under the laws of the United States or any state thereof;

(b) the successor entity assumes the Guarantor's obligations under this Guarantee;

(c) after giving effect to the transaction, no Event of Default, and no event which, after notice and lapse of time, or both, would become an Event of Default, has occurred and is continuing; and

(d) the Guarantor delivers to the Trustee certificates and opinions to the effect that the transaction complies with the Indenture.

Upon any such consolidation or merger or conveyance, transfer or lease of substantially all the properties and assets of the Guarantor any person, the successor person will succeed to, and be substituted for, such Guarantor under the Indenture and this Guarantee, and the Guarantor, except in the case of a lease of its properties and

assets substantially as an entirety, will be discharged and released from all obligations and covenants under the Indenture and this Guarantee.

SECTION 13. Governing Law. This Guarantee shall be governed by, and construed in accordance with, the law of the State of New York, without regard to any otherwise governing principles of conflicts of law.

EXHIBIT 10.13
GUARANTEE
(Litton of Outstanding NGSC Indenture Debt)

GUARANTEE dated as of April 3, 2001 (this "Guarantee") made by Litton Industries, Inc., a Delaware corporation ("Guarantor") in favor of and for the benefit of The Chase Manhattan Bank, as trustee (the "Trustee") for the Holders (as such term is defined in the Indenture referred to below) of the 8.625% Notes due 2004, the 9.735% Debentures due 2024, the 7% Notes due 2006, the 7.75% Debentures due 2016 and the 7.875% Debentures due 2026 (collectively, the

"Securities") of Northrop Grumman Systems Corporation (formerly Northrop Grumman Corporation) (the "Company").

WHEREAS, the Company has entered into an Indenture dated as of October 15, 1994 between the Company and the Trustee (as amended, modified and supplemented from time to time with respect to the Securities, the "Indenture"). Capitalized terms not otherwise defined herein shall have the meanings set forth in the Indenture; and

WHEREAS, Guarantor and the Company are both subsidiaries of Northrop Grumman Corporation (formerly NNG, Inc.); and

WHEREAS, in consideration for the guarantee of the Securities by the Guarantor, the Company has agreed to guarantee certain outstanding indenture debt of the Guarantor.

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

-1-

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 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.

-2-

(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, 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;

-3-

(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.

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

-4-

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 held in trust for the benefit of the Holders and the Trustee and shall forthwith be paid to the Trustee, on behalf of the Holders, to be credited and applied to the Guaranteed Obligations, whether matured or unmatured.

SECTION 6. Amendments, Etc. No amendment or waiver of any provision of this Guarantee and no consent to any departure by the Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by the Trustee, on behalf of the Holders, pursuant to the provisions of Article Nine of the Indenture, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given.

SECTION 7. Notices, Etc. All notices and other communications provided for hereunder shall be in writing and delivered in person or mailed by first-class mail, if to the Guarantor, addressed to it at the address of the Company at 1840 Century Park East, Los Angeles, California 90067, Attention:

SECTION 8. No Waiver; Remedies. No failure on the part of any Holder or the Trustee to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right.

SECTION 9. Continuing Guarantee.
