Risk Factors We are heavily dependent on sales to the United States Government Approximately 75% of our net sales in 1998 were to the United States Government. The U.S. Government programs in which Northrop Grumman is involved must compete with other defense contractors for a limited number of defense programs for uncertain levels of funding. These defense programs are also normally subject to termination by the government for convenience. The funding of defense programs competes with non-defense spending of the U.S. Government. Budget decisions made by the U.S. Government are outside of our control and have long-term consequences for the size and structure of Northrop Grumman. Page 2 of 11 The market for Northrop Grumman stock can be volatile During the twelve months prior to August 20, 1999, the market price of our common stock as quoted on the New York Stock Exchange has ranged from a low of $56.625 per share to a high of $84 per share. The price of our common stock may, at times, be volatile. Forward-looking Statements We make statements in this prospectus and the documents incorporated by reference that we believe are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Sometimes these statements will contain words such as "believes," "expects," "intends," "plans," and other similar words. These statements are not guarantees of our future performance and are subject to risks, uncertainties and other important factors that could cause our actual performance or achievements to be materially different from those we may project. These forward-looking statements also represent our estimates and assumptions only as of the date they were made. These risks, uncertainties and factors include: o our successful performance of internal plans; o government customers' budgetary restraints; o customer changes in short-range and long-range plans; o domestic and international competition in both the defense and commercial areas; o product performance; o continued development and acceptance of new products; o performance issues with key suppliers and subcontractors; o government import and export policies; o termination of government contracts, which may include termination for the convenience of the government; o the outcome of political and legal processes; o legal, financial and governmental risks related to international transactions and global needs for military and commercial aircraft and electronic systems and support; and o other economic, political and technological risks and uncertainties. Page 3 of 11 Given these uncertainties, you should not place undue reliance on these forward-looking statements. The future results may differ materially from those expressed in the forward-looking statements. For these statements, we intend to claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Please see the documents incorporated by reference for more information on these factors.

Page 5 of 11 Description of Common Stock Our certificate of incorporation provides that we have authority to issue 200,000,000 shares of common stock, par value $1.00 per share. As of August 16, 1999, 69,431,351 shares of common stock were outstanding. Our common stock is listed on the New York Stock Exchange and the Pacific Stock Exchange. Dividends. Dividends may be paid on the common stock and on any class or series of stock entitled to participate with the common stock as to dividends, but only when and as declared by our board of directors. Voting Rights. Each holder of our common stock is entitled to one vote per share on all matters submitted to a vote of stockholders and does not have cumulative voting rights. Liquidation. If we liquidate, holders of common stock are entitled to receive all remaining assets available for distribution to stockholders after satisfaction of our liabilities and the preferential rights of any preferred stock that may be outstanding at that time. Our outstanding common shares are fully paid and nonassessable. The holders of our common stock do not have any preemptive, conversion or redemption rights. The registrar and transfer agent for our common stock is ChaseMellon Shareholder Services, L.L.C. Preferred Stock Purchase Rights. On September 16, 1998, our board of directors declared a dividend distribution of one preferred share purchase right for each outstanding share of common stock. Each right, when it becomes exercisable, entitles the registered holder to purchase from us one one-thousandth of a share of our Series A junior participating preferred stock, $1.00 par value per share, at a price of $250.00 per one one-thousandth of a preferred share, subject to adjustment. These rights attached to all certificates representing our common shares outstanding on October 2, 1998, and attach to common shares issued after that date until the distribution date described below. No separable right certificates will be distributed. The rights will separate from our common shares on the distribution date. Distribution date means the date which is the earliest to occur of: o a person or group of affiliated or associated persons having acquired beneficial ownership of 15% or more of our outstanding common shares, except pursuant to a permitted offer; or o 10 days, or such later date as our board of directors may determine, following the commencement of, or announcement of an intention to make, a tender offer or exchange offer, the consummation of which would result in a person or group acquiring 15% of our outstanding voting power. We may redeem the rights at the option of our board of directors for $0.01 per right at any time prior to the earlier of the expiration of the rights or on the date that a person or persons acquire 15% of our voting power. Our board of directors may amend the rights at any time without stockholder approval. The rights will expire by their terms on October 31, 2008. Page 6 of 11 Some Important Charter and Statutory Provisions. Our certificate of incorporation provides for the division of our board of directors into 3 classes of directors, each serving staggered, 3-year terms. Our certificate of incorporation further provides generally that any alteration, amendment or repeal of the following sections of our certificate of incorporation requires the approval of the holders of at least 80% of our outstanding voting power, unless such action is approved by a majority of our board of directors: (a) the election and classification of the board of directors; (b) liability of directors; and (c) the vote requirements for amendments to our certificate of incorporation. If any of these changes to our certificate of incorporation are approved by our board of directors, the approval of a majority of our outstanding voting power is required to make these changes effective. These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or our management. We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, the statute prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless: (1) prior to that date, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; (2) when the transaction that resulted in such person becoming an interested stockholder is completed, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding, for purposes of determining the number of shares outstanding, shares owned by some directors or employee stock plans; or (3) on or after the date the stockholder became an interested stockholder, the business combination is approved by the board of directors and authorized by the affirmative vote, and not by the written consent, of at least two-thirds of outstanding voting stock, excluding the stock owned by the interested stockholder. A "business combination" includes a merger, asset sale, or other transaction resulting in a financial benefit to the interested stockholder. An "interested stockholder" is a person who, other than the corporation and any direct or indirect majority-owned subsidiary of the corporation, together with affiliates and associates, owns or, as an affiliate or associate, within three years prior, did own, 15% or more of the corporation's outstanding voting stock. Page 7 of 11 Plan of Distribution Neither we nor the selling stockholders have employed an underwriter for the sale of common stock by the selling stockholders. We will pay all expenses, other than broker or dealer discounts and commissions, stock transfer taxes and the fees and disbursements of separate counsel, if any, retained by the selling stockholders, associated with the sale of the common stock. The securities covered by this prospectus may be sold by or for the account of the selling stockholders pursuant to this prospectus or pursuant to Rule 144 under the Securities Act, if available. The selling stockholders may offer their shares of common stock directly or through pledgees, donees, transferees or other successors in interest at various times in one or more of the following transactions, which may include block sales: o on any stock exchange on which the shares of common stock may be listed at the time of sale, either through a broker or otherwise; o in negotiated transactions; o in a combination of any of the above transactions; or o through any other available market transaction. The selling stockholders may offer their shares of common stock at any of the following prices: o fixed prices which may be changed; o market prices prevailing at the time of sale; o prices related to such prevailing market prices; or o at negotiated prices. The selling stockholders may effect these transactions by selling shares to or through broker-dealers, and all such broker-dealers may receive compensation in the form of discounts, concessions, or commissions from the selling stockholders and/or the purchasers of shares of common stock for whom these broker-dealers may act as agents or to whom they sell as principals, or both. In connection with the distribution of the shares of offered common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers. In connection with these transactions, broker-dealers may engage in short sales of shares of common stock in the course of hedging the positions they assume with the selling stockholders. The selling stockholders may also sell shares of common stock short and deliver shares of offered common stock to close out these short positions. The selling stockholders may also enter into option or other transactions with broker-dealers which require the delivery to the broker-dealer of shares of offered common stock, which the broker-dealer may resell or otherwise transfer pursuant to this prospectus. The selling Page 8 of 11 stockholder may also lend or pledge the shares of offered common stock to a broker-dealer and the broker-dealer may sell the shares of common stock so lent or upon default the broker-dealer may effect sales of the pledged shares pursuant to this prospectus. The selling stockholders may also pledge shares of offered common stock to a lender other than a broker-dealer, and upon default the lender may sell the shares of common stock so pledged pursuant to this prospectus. The selling stockholders may also contribute or sell shares of offered common stock to trusts or other entities for the benefit of the contributing selling stockholder and members of his or her family. Any broker-dealer acquiring common stock from the selling stockholders may sell the shares either directly, in its normal market-making activities, through or to other brokers on a principal or agency basis or to its customers. Any of these sales may be at prices then prevailing on the New York Stock Exchange or the Pacific Stock Exchange, or at prices related to prevailing market prices or at negotiated prices to its customers or a combination of these methods. The selling stockholders and any broker-dealers that act in connection with the sale of the common stock might be deemed to be "underwriters" pursuant to Section 2(11) of the Securities Act of 1933; any commissions received by them and any profit on the resale of shares as principals might be deemed to be underwriting discounts and commissions under that Act. Any of these commissions, as well as stock transfer taxes and the fees and disbursements of separate counsel, if any, retained by the selling stockholders, are payable by the selling stockholders. We have not registered or qualified offers and sales of shares of the common stock under the laws of any country, other than the United States. To comply with the securities laws of some states, if applicable, the selling stockholders will offer and sell their shares of common stock in those jurisdictions only through registered or licensed brokers or dealers. Unless an exemption from the registration and qualification requirements of these states is available, we may be required to register and qualify the offered common stock in those states which the selling stockholders may reasonably request.
