SUMMARY

The following summary is qualified in its entirety by the more detailed information included elsewhere in this prospectus supplement and the accompanying prospectus. Because this is a summary, it may not contain all the information that may be important to you. You should read the entire prospectus supplement and the accompanying prospectus, including “Risk Factors” beginning on page S-3, and the financial statements and the notes to those statements and other information incorporated by reference, before making a decision whether to invest in the notes.

The Company

We are a global security company that is principally engaged in the research, design, development, manufacture, integration, and sustainment of advanced technology systems and products. We also provide a broad range of management, engineering, technical, scientific, logistic and information services. We serve both domestic and international customers with products and services that have defense, civil and commercial applications, with our principal customers being agencies of the U.S. Government.

In 2008, 84% of our net sales were made to the U.S. Government, either as a prime contractor or as a subcontractor. Each of our business segments is heavily dependent on sales to the U.S. Government. Our U.S. Government sales were made to both Department of Defense (DoD) and non-DoD agencies. Sales to foreign governments (including foreign military sales funded, in whole or in part, by the U.S. Government) amounted to 13% of net sales in 2008, while 3% of our net sales were made to commercial and other customers. Our main areas of focus are in defense, space, intelligence, homeland security and government information technology.

We operate in four principal business segments: Electronic Systems, Information Systems & Global Services, Aeronautics and Space Systems.

Our principal executive offices are located at 6801 Rockledge Drive, Bethesda, Maryland 20817, and our telephone number at that address is (301) 897-6000. Our website home page on the Internet is www.lockheedmartin.com. We make our website content available for information purposes only. It should not be relied upon for investment purposes, and it is not incorporated by reference into this prospectus supplement or the accompanying prospectus.

Governing Law Maryland law will govern the Indenture and the notes.

S-2

RISK FACTORS

An investment in the notes involves risk. You should carefully consider the following risks, together with the information included in or incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding whether an investment in the notes is suitable for you. In addition to the risk factors set forth below, we also specifically incorporate by reference into this prospectus supplement the section captioned “Item IA. Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2008. If any of these risks actually occurs, our business, results of operations or financial condition could be materially and adversely affected. In such an event, the trading prices of the notes could decline, and you might lose all or part of your investment.

The indenture does not limit the amount of indebtedness that we may incur.

The indenture under which the notes will be issued does not limit the amount of indebtedness that we may incur. The indenture does not contain any financial covenants or other provisions that would afford the holders of the notes any substantial protection in the event we participate in a highly leveraged transaction.

The notes are obligations exclusively of Lockheed Martin Corporation and not of our subsidiaries and payment to holders of the notes will be structurally subordinated to the claims of our subsidiaries’ creditors.

The notes will be our general unsecured obligations and will rank equally with all of our other current and future unsecured and unsubordinated debt and senior in right of payment to all of our future subordinated debt. The notes are not guaranteed by any of our subsidiaries. Although most of our business currently is conducted through Lockheed Martin Corporation, to the extent that we were to conduct operations through subsidiaries, the assets of our subsidiaries would not be available directly for payments on the notes. The notes effectively will be subordinated to all indebtedness and other liabilities of our subsidiaries to the extent of our subsidiaries’ assets.

There is no public market for the notes, which could limit their market price or your ability to sell them.

The notes are new issues of securities for which there currently are no trading markets. As a result, we cannot provide any assurance that markets will develop for the notes or that you will be able to sell your notes. If the notes are traded after their initial issuance, they may trade at a discount from their initial offering prices. Future trading prices of the notes will depend on many factors, including prevailing interest rates, the market for similar securities, general economic conditions and our financial condition, performance and prospects. Accordingly, you may be required to bear the financial risk of an investment in the notes for an indefinite period of time. We do not intend to apply for listing or quotation of the notes on any securities exchange or automated quotation system.

S-3

USE OF PROCEEDS

We estimate that the net proceeds from this offering, after deducting estimated fees and expenses and underwriting discounts and commissions, will be approximately $1,474,175,000.

We expect to use the net proceeds from this offering for general corporate purposes. These purposes may include the repayment of indebtedness, future acquisitions, capital expenditures, working capital and any other corporate purpose. Until we apply the net proceeds for specific purposes, we may invest the net proceeds in cash equivalents or short-term investments.

S-4

CAPITALIZATION

The following table sets forth our capitalization on a consolidated basis as of September 27, 2009, and as adjusted to reflect the issuance of the notes, net of the underwriting discounts and our estimated offering expenses and the application of the net proceeds as described under “Use of Proceeds” above assuming that all of the net proceeds from the sale of the notes would be used for general corporate purposes. This table should be read in conjunction with our consolidated financial statements and the related notes as included in our Annual Report on Form 10-K for the year ended December 31, 2008 and as included in our quarterly report on Form 10-Q for the quarter ended September 27, 2009.

RATIO OF EARNINGS TO FIXED CHARGES

We have presented in the table below our historical consolidated ratio of earnings to fixed charges for the periods shown.

	Nine Months Ended September 27, 2009	Year Ended December 31,
		2008	2007	2006	2005	2004
Ratio of earnings to fixed charges	13.1	12.9	11.8	9.7	7.3	4.6

Our computation of the ratio of earnings to fixed charges includes our consolidated subsidiaries and companies in which we own at least 20% but less than or equal to 50% of the equity. “Earnings” are determined by adding “total fixed charges,” excluding interest capitalized, to earnings before income taxes, eliminating equity in undistributed earnings and adding back losses (or deducting undistributed earnings) of companies in which we own at least 20% but less than or equal to 50% of the equity. “Total fixed charges” consists of interest on all indebtedness (whether expensed or capitalized), amortization of debt discount or premium, capitalized expenses related to indebtedness and an interest factor attributable to rents.

S-6

DESCRIPTION OF THE NOTES

The following description of the particular terms of the notes supplements the description of the general terms and provisions of debt securities set forth under “Description of Debt Securities” in the accompanying prospectus. We refer you to the accompanying prospectus for that description. If this description differs in any way from the general description of the debt securities in the accompanying prospectus, you should rely on this description.

General

We will issue the 2019 notes and the 2039 notes as separate series of senior debt securities under the Indenture dated as of March 11, 2008 (the “Indenture”), between us and The Bank of New York Mellon, as Trustee. The summaries of certain provisions of the Indenture described below are not complete and are qualified in their entirety by reference to all the provisions of the Indenture. The Indenture has been filed as an exhibit to our Current Report on Form 8-K filed March 12, 2008, which is incorporated by reference in our registration statement of which the accompanying prospectus is a part.

The notes will be our general unsecured obligations and will rank equally with all of our other current and future unsecured and unsubordinated debt. The notes are not guaranteed by any of our subsidiaries. The notes effectively will be subordinated to all of our secured debt (as to the collateral pledged to secure that debt) and to all indebtedness and other liabilities of our subsidiaries to the extent of our subsidiaries’ assets. The covenants in the Indenture will not afford the holders of the notes protection in the event of a decline in our credit quality resulting from highly leveraged or other transactions involving us.

We may issue separate series of debt securities under the Indenture from time to time without limitation on the aggregate principal amount. We may specify a maximum aggregate principal amount for the debt securities of any series.

The 2019 notes will initially be limited to $900,000,000 in aggregate principal amount, and the 2039 notes will initially be limited to $600,000,000 in aggregate principal amount. The notes will be issued in minimum denominations of $2,000 and $1,000 multiples above that amount.

The 2019 notes will mature on November 15, 2019, and the 2039 notes will mature on November 15, 2039.

The notes will bear interest from November 18, 2009 or from the most recent interest payment date to which interest has been paid or provided for. We will pay interest on the notes semiannually in arrears on May 15 and November 15 to the registered holders of the notes as of the close of business on the immediately preceding May 1 and November 1, respectively, whether or not such day is a business day. The first interest payment date will be May 15, 2010. The notes will be issued only in denominations of $2,000 and $1,000 multiples above that amount.

We may, without the consent of the holders of a series of notes, issue additional notes of that series and thereby increase the principal amount of the notes of that series in the future, on the same terms and conditions and with the same CUSIP number as the notes of that series offered in this prospectus supplement.

We do not intend to apply to list the notes on any securities exchange or to have the notes quoted on any automated quotation system.

From time to time, in our sole discretion, depending upon market, pricing and other conditions, as well as our cash balances and liquidity, we or our affiliates may seek to repurchase a portion of the notes. Any such future purchases may be made in the open market, privately-negotiated transactions, tender offers or otherwise, in each case in our sole discretion.

S-7

No Sinking Fund

The notes will not be entitled to the benefit of a sinking fund.

Optional Redemption

Each series of notes will be redeemable as a whole or in part, at our option, at any time, at a redemption price equal to the greater of:

• 100% of the principal amount of the notes to be redeemed; and

• the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of interest accrued to the date of redemption) on the notes to be redeemed discounted to the redemption date semiannually (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) for the series of notes, plus 15 basis points with respect to the 2019 notes and plus 20 basis points with respect to the 2039 notes.

In either case, the redemption price will also include any accrued and unpaid interest on the series of notes to the date of redemption. The Independent Investment Banker (as defined below) will calculate the redemption price.

“Treasury Rate” means, with respect to the notes on any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue (as defined below), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the notes that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity with the remaining term of the notes.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of the bid and asked prices for the Comparable Treasury Issue (expressed as a percentage of its principal amount) on the third business day preceding such redemption date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated “Composite 3:30 p.m. Quotations for U.S. Government Securities” or (2) if such release (or any successor release) is not published or does not contain such prices on such business day, (a) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (b) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Trustee after consultation with us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer for any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third business day preceding such redemption date.

“Reference Treasury Dealer” means each of Citigroup Global Markets Inc., J.P. Morgan Securities Inc., Banc of America Securities LLC and Morgan Stanley & Co. Incorporated, and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we shall replace that former dealer with another Primary Treasury Dealer.

We will mail notice of any redemption between 20 days and 60 days before the redemption date to each holder of the notes to be redeemed.

Unless we default in payment of the redemption price and accrued interest, if any, on and after the redemption date, interest will cease to accrue on the notes or portions of the notes called for redemption.

S-8

In the case of a partial redemption of a series of notes, selection of the notes in such series for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems fair and appropriate. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed; provided that the unredeemed portion of the note shall be $2,000 in principal amount and $1,000 multiples above that amount. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note.

Covenants

The notes are subject to the restrictive covenants described under the section entitled “Description of Debt Securities—Certain Covenants” in the accompanying prospectus.

Consolidation, Merger and Sale of Assets

The notes are subject to some limitations on our ability to enter into some consolidations, mergers or transfers of substantially all of our assets as described under the section entitled “Description of Debt Securities—Consolidation, Merger or Sale” in the accompanying prospectus.

Events of Default

The notes of each series are subject to the events of default described under the section entitled “Description of Debt Securities—Events of Default” in the accompanying prospectus. In connection with the trustee’s exercise of any rights or remedies at the direction of holders of the notes, the trustee may require an indemnity satisfactory to it from such holders.

Modification and Waiver

The notes are subject to provisions allowing, under some conditions, the modification or amendment of the Indenture or the notes or waiving our compliance with some provisions of the Indenture or the notes, as described under the section entitled “Description of Debt Securities—Changes to the Indenture” in the accompanying prospectus.

Defeasance and Discharge Provisions

We may defease certain of our obligations with respect to a series of notes or discharge our obligations with respect to a series of notes by irrevocably depositing with the Trustee, in trust, cash or government securities sufficient to pay all sums due on such series of notes. The establishment of such a trust will be conditioned on the delivery by us to the Trustee of an opinion of counsel, who may be counsel to Lockheed Martin, to the effect that, based on applicable U.S. federal income tax law or a ruling published by the United States Internal Revenue Service, the defeasance or discharge, as the case may be, will not be deemed, or result in, a taxable event with respect to the holders of the notes.

Book-Entry Delivery and Settlement

We will issue each series of notes in the form of one or more permanent global notes in definitive, fully registered, book-entry form. The global notes will be deposited with or on behalf of The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., as nominee of DTC. Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC.

S-9

DTC has advised us as follows:

• DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”);

• DTC holds securities that its participants deposit with DTC and facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates;

• direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations;

• access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly; and

• the rules applicable to DTC and its participants are on file with the SEC.

We expect that under procedures established by DTC:

• upon deposit of the global notes with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriters with portions of the principal amounts of the global notes; and

• ownership of the notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.

The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by the global note for all purposes under the indenture and under the notes. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or the global note.

Neither we nor the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC or for maintaining, supervising or reviewing any records of those organizations relating to the notes.

Payments on the notes represented by the global note will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by the global note, will credit participants’ accounts with payments in amounts proportionate to their

S-10

respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global note held through such participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

Settlement for the notes will be made by the underwriters in immediately available funds. The notes will trade in DTC’s Same-Day Funds Settlement System until maturity. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds. So long as DTC continues to make its Settlement System available to us, it is anticipated that payments of principal of and interest on the notes will be made by us in immediately available funds.

S-11

CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES

The following discussion summarizes certain U.S. federal income tax consequences of the purchase, beneficial ownership and disposition of the notes by a U.S. Holder (as defined below). Also following is general information regarding the U.S. federal tax consequences of the purchase, beneficial ownership and disposition of the notes by a holder that is not a U.S. Holder (“Non-U.S. Holder”).

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), regulations issued under the Code, judicial authority and administrative rulings and practice, all of which are subject to change and differing interpretation. Any such change may be applied retroactively and may adversely affect the U.S. federal income tax consequences described in this prospectus supplement. This summary addresses only tax consequences to investors that purchase the notes pursuant to this prospectus supplement at the price set forth on the cover page. This summary assumes the notes will be held as capital assets within the meaning of Section 1221 of the Code. This summary does not discuss all of the tax consequences that may be relevant to particular investors or to investors subject to special treatment under the U.S. federal income tax laws (such as insurance companies, financial institutions, tax-exempt organizations, partnerships or other pass-through entities (and persons holding the notes through a partnership or other pass-through entity), retirement plans, regulated investment companies, securities dealers, traders in securities who elect to apply a mark-to-market method of accounting, persons holding the notes as part of a “straddle,” “constructive sale,” or a “conversion transaction” for U.S. federal income tax purposes, or as part of some other integrated investment, expatriates or persons whose functional currency for tax purposes is not the U.S. dollar). This summary also does not discuss any tax consequences arising under the laws of any state, local, foreign or other tax jurisdiction or, except to the extent provided below, any tax consequences arising under U.S. federal tax laws other than U.S. federal income tax laws. The term “holder” as used in this section refers to a beneficial holder of the notes and not the record holder.

Persons considering the purchase of the notes, including any persons who would be Non-U.S. Holders, should consult their own tax advisors concerning the application of U.S. federal tax laws to their particular situations as well as any consequences of the purchase, beneficial ownership and disposition of the notes arising under the laws of any other taxing jurisdiction.

U.S. Federal Income Tax Consequences to U.S. Holders

The following is a general discussion of U.S. federal income tax consequences of the purchase, beneficial ownership and disposition of the notes by a holder that is a “U.S. Holder.” For purposes of this discussion, a U.S. Holder means:

• a citizen or resident of the United States;

• a corporation or other business entity taxable as a corporation created or organized in or under the laws of the United States or any State or the District of Columbia;

• an estate whose income is subject to U.S. federal income taxation regardless of its source; or

• a trust if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have the authority to control all substantial decisions of the trust, or certain electing trusts that were in existence on August 20, 1996 and were treated as domestic trusts before that date.

If a partnership holds notes, the U.S. federal income tax treatment of a partner generally will depend on the status of the partner and upon the activities of the partnership. Persons who are partners in a partnership holding notes should consult their tax advisors.

S-12

Taxation of Interest

Stated interest on the notes will be taxable to a U.S. Holder as ordinary interest income. A U.S. Holder must report this income either when it accrues or is received, depending on the holder’s method of accounting for U.S. federal income tax purposes.

Treatment of Dispositions of Notes

Upon the sale, exchange, retirement or other taxable disposition of a note, a U.S. Holder generally will recognize gain or loss equal to the difference between the amount received on such disposition (other than amounts received in respect of accrued and unpaid interest, which will be taxable as interest to the extent not previously included in income) and the U.S. Holder’s tax basis in the note. A U.S. Holder’s tax basis in a note generally will be the cost of the note to the U.S. Holder less any principal payments received by that U.S. Holder. Gain or loss realized on the sale, exchange, retirement or other taxable disposition of a note generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of such sale, exchange, retirement or other taxable disposition, the U.S. Holder has held the note for more than one year. The ability to deduct capital losses is subject to limitation under U.S. federal income tax laws. Net long-term capital gain recognized by a non-corporate U.S. Holder is generally taxed at preferential rates.

U.S. Federal Tax Consequences to Non-U.S. Holders

The following is a general discussion of U.S. federal income tax consequences and, only to the extent provided below, certain U.S. federal estate tax consequences of the purchase, beneficial ownership and disposition of the notes by a holder that is a “Non-U.S. Holder.” This discussion does not address all aspects of U.S. federal income or estate taxation that may be relevant to such Non-U.S. Holders in light of their particular circumstances. For example, special rules may apply to a Non-U.S. Holder that is a “controlled foreign corporation” or a “passive foreign investment company.”

For purposes of the following discussion, any interest income and any gain realized on the sale, exchange, retirement or other taxable disposition of the notes will be considered “U.S. trade or business income” if such interest income or gain is (i) effectively connected with the conduct of a trade or business in the United States and (ii) in the case of a treaty resident, attributable to a permanent establishment (or in the case of an individual, to a fixed base) in the United States.

Taxation of Interest

A Non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax in respect of interest income on the notes if each of the following requirements is satisfied:

• The interest is not U.S. trade or business income.

• The Non-U.S. Holder provides to us or the paying agent an appropriate completed statement on an IRS Form W-8BEN, together with all appropriate attachments, signed under penalties of perjury, identifying the Non-U.S. Holder and stating, among other things, that the Non-U.S. Holder is not a U.S. person, and neither we nor the paying agent have actual knowledge or reason to know that such holder is a U.S. person. If a note is held through a securities clearing organization, bank or another financial institution that holds customers’ securities in the ordinary course of its trade or business, this requirement is satisfied if (i) the Non-U.S. Holder provides such a form to the organization or institution, and (ii) the organization or institution, under penalties of perjury, certifies to us that it has received such a form from the beneficial owner or another intermediary and furnishes us or the paying agent with a copy. In addition, Non-U.S. Holders that are entities rather than individuals must satisfy certain special certification requirements.

S-13

• The Non-U.S. Holder does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote.

• The Non-U.S. Holder is not a “controlled foreign corporation” that is actually or constructively related to us.

If these conditions are not met, a 30% withholding tax will apply to interest income on the notes, unless one of the following two exceptions is satisfied. The first exception is that an applicable income tax treaty reduces or eliminates such tax, and a Non-U.S. Holder claiming the benefit of that treaty provides to us or the paying agent a properly executed IRS Form W-8BEN and neither we nor the paying agent have actual knowledge or reason to know that such holder is a U.S. person. The second exception is that the interest is U.S. trade or business income and the Non-U.S. Holder provides an appropriate statement to that effect on an IRS Form W-8ECI. In the case of the second exception, such Non-U.S. Holder generally will be subject to U.S. federal income tax with respect to all income from the notes in the same manner as U.S. Holders, as described above. Additionally, in such event, Non-U.S. Holders that are corporations could be subject to an additional “branch profits” tax on such income. Non-U.S. Holders should consult their own tax advisors regarding the application of U.S. federal income tax laws to their particular situations.

Treatment of Dispositions of Notes

Generally, a Non-U.S. Holder will not be subject to U.S. federal income tax on gain realized upon the sale, exchange, retirement or other disposition of a note unless:

• such holder is an individual present in the United States for 183 days or more in the taxable year of the sale, exchange, retirement or other disposition and certain other conditions are met; or

• the gain is U.S. trade or business income.

If a Non-U.S. Holder is an individual described in the first bullet point above, such holder will be subject to a flat 30% tax (subject to reductions under an applicable income tax treaty) on the gain derived from the sale, exchange, retirement or other disposition, which may be offset by U.S.-source capital losses, even though such holder is not considered a resident of the United States. If a Non-U.S. Holder is described in the second bullet point above, it will be subject to tax on the net gain derived from the sale, exchange, retirement, or other disposition in the same general manner as if the Non-U.S. Holder were a U.S. Holder, unless an applicable income tax treaty provides otherwise. In addition, if a Non-U.S. Holder is a foreign corporation that falls under the second bullet point above, it may be subject to an additional “branch profits” tax on such income.

Treatment of Notes for U.S. Federal Estate Tax Purposes

A note held, or treated as held, by an individual who is a Non-U.S. Holder at the time of his or her death will not be subject to U.S. federal estate tax, provided the Non-U.S. Holder does not at the time of death actually or constructively own 10% or more of the combined voting power of all classes of our stock and payments of interest on such notes would not have been considered U.S. trade or business income.

U.S. Information Reporting Requirements and Backup Withholding Tax

Information reporting requirements generally will apply to certain payments to a U.S. Holder of interest and principal on, and proceeds received from the sale, exchange, retirement or other taxable disposition of, a note, unless the holder is an exempt recipient, such as a corporation. In addition, backup withholding may apply to such payments or proceeds if the U.S. Holder (that is not an exempt recipient) fails to furnish the payor with a correct taxpayer identification number or other required certification, has been notified by the IRS that it is subject to backup withholding for failing to report interest or dividends required to be shown on the holder’s federal income tax returns, or otherwise fails to comply with applicable requirements of the backup withholding rules.

S-14

In general, a Non-U.S. Holder will not be subject to backup withholding with respect to interest or principal payments on the notes if such holder certifies under penalties of perjury that it is not a U.S. person and the payor does not have actual knowledge or reason to know that such holder is a U.S. person. However, information reporting may still apply with respect to interest payments.

In addition, a Non-U.S. Holder will not be subject to backup withholding with respect to the proceeds of the sale, exchange, retirement or other taxable disposition of a note made within the United States or conducted through certain United States financial intermediaries if such holder certifies under penalties of perjury that it is not a U.S. person and the payor does not have actual knowledge or reason to know that such holder is a U.S. person or such holder otherwise establishes an exemption. Payment of such proceeds generally will not be subject to information reporting if the Non-U.S. Holder certifies as to its taxpayer identification number or otherwise establishes an exemption. Non-U.S. Holders should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of exemptions and the procedure for obtaining such exemptions, if available.

Backup withholding is not an additional tax and may be refunded or credited against the holder’s U.S. federal income tax liability, provided that certain required information is timely furnished to the IRS. The information reporting requirements may apply regardless of whether withholding is required. Copies of the information returns reporting such interest and withholding may be made available to the tax authorities in foreign countries under the provisions of a tax treaty or agreement.

S-15

UNDERWRITING

We and the underwriters for the offering named below have entered into an underwriting agreement with respect to the notes. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of notes indicated in the following table.

Citigroup Global Markets Inc.	$	270,000,000	$	180,000,000
J.P. Morgan Securities Inc.	$	270,000,000	$	180,000,000
Banc of America Securities LLC	$	90,000,000	$	60,000,000
Morgan Stanley & Co. Incorporated	$	90,000,000	$	60,000,000
Goldman, Sachs & Co.	$	36,000,000	$	24,000,000
RBS Securities Inc.	$	36,000,000	$	24,000,000
BNP Paribas Securities Corp.	$	18,000,000	$	12,000,000
Lloyds TSB Bank plc	$	18,000,000	$	12,000,000
Mitsubishi UFJ Securities (USA), Inc.	$	18,000,000	$	12,000,000
Mizuho Securities USA Inc.	$	18,000,000	$	12,000,000
UBS Securities LLC	$	18,000,000	$	12,000,000
Wells Fargo Securities, LLC	$	18,000,000	$	12,000,000
Total	$	900,000,000	$	600,000,000

The underwriters are committed to take and pay for all of the notes being offered, if any are taken.

Notes sold by the underwriters to the public initially will be offered at the initial public offering price for the series of notes set forth on the cover of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to 0.40% of the principal amount of 2019 notes and 0.50% of the principal amount of 2039 notes. Any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price of up to 0.25% of the principal amount of 2019 notes and 0.25% of the principal amount of the 2039 notes. If all the notes are not sold at their initial offering price, the underwriters may change the offering prices and the other selling terms. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The notes are new issues of securities with no established trading markets. We have been advised by the underwriters that the underwriters intend to make markets in the notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading markets for the notes.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market prices of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

S-16

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $1.6 million.

We have agreed to indemnify the several underwriters against certain liabilities, including certain liabilities under the Securities Act of 1933.

Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory, investment banking and commercial banking services for us, for which they received or will receive customary fees and expenses.

VALIDITY OF THE NOTES

The validity of the notes offered hereby will be passed upon for us by Hogan & Hartson LLP, Baltimore, Maryland. Davis Polk & Wardwell LLP, New York, New York, will act as counsel for the underwriters.

EXPERTS

Ernst & Young LLP, independent registered public accounting firm, has audited our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2008, and the effectiveness of our internal control over financial reporting as of December 31, 2008, as set forth in their reports, which are incorporated by reference herein. Our consolidated financial statements are incorporated by reference in reliance upon Ernst & Young LLP’s reports, given on their authority as experts in accounting and auditing.

With respect to our unaudited condensed consolidated interim financial information for the three-month periods ended March 29, 2009 and March 30, 2008, the three- and six-month periods ended June 28, 2009 and June 29, 2008, and the three- and nine-month periods ended September 27, 2009 and September 28, 2008 incorporated by reference herein, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated April 21, 2009, July 22, 2009, and October 22, 2009 included in our Quarterly Reports on Forms 10-Q for the quarters ended March 29, 2009, June 28, 2009, and September 27, 2009 and incorporated by reference herein, state that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their reports on the unaudited interim financial information because those reports are not a “report” or a “part” of the registration statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (the “SEC”) utilizing a “shelf” registration process. Using this process, we may offer and sell Debt Securities in one or more offerings.

We have not authorized anyone to give any information or to make any representations concerning the Debt Securities we may offer except those which are in this prospectus, any prospectus supplement that is delivered with this prospectus or any documents incorporated by reference into this prospectus. If anyone gives any other information or representation, you should not rely on it. This prospectus is not an offer to sell or a solicitation of an offer to buy any securities other than the Debt Securities that are referred to in the prospectus supplement. This prospectus is not an offer to sell or a solicitation of an offer to buy Debt Securities in any circumstances in which the offer or solicitation is unlawful. You should not interpret the delivery of this prospectus, or any offer or sale of Debt Securities, as an indication that there has been no change in our affairs since the date of this prospectus.

Neither this prospectus, any accompanying prospectus supplement nor any free writing prospectus that we have authorized contain all of the information included in the registration statement. We have omitted parts of the registration statement as permitted by the SEC’s rules and regulations. For further information, we refer you to the registration statement on Form S-3 we filed with the SEC on March 11, 2008, which can be read at the SEC web site or at the SEC offices mentioned under the headings “Where To Find Additional Information” and “Incorporation of Certain Information by Reference.” The registration statement also includes exhibits. Statements contained in this prospectus, any prospectus supplement and any free writing prospectus that we have authorized, or that are incorporated by reference into this prospectus or a prospectus supplement, about the provisions or contents of any agreement or other document are not necessarily complete. If SEC rules and regulations require that any agreement or document be filed as an exhibit to the registration statement and we file the agreement or document, you should refer to that agreement or document for a complete description of these matters.

This prospectus provides you with a general description of the Debt Securities we may offer. Each time we sell any of the Debt Securities, we will provide a prospectus supplement or free writing prospectus that will contain specific information about the terms of that offering and the securities being offered at that time. The prospectus supplement or free writing prospectus also may add, update or change information contained in this prospectus, and any statement in this prospectus will be modified or superseded by any inconsistent statement in a prospectus supplement or free writing prospectus. You should read both this prospectus and any prospectus supplement or free writing prospectus together with the additional information described under the headings “Where To Find Additional Information” and “Incorporation of Certain Information by Reference.”

RISK FACTORS

An investment in our Debt Securities involves risks. We urge you to consider carefully the risks described in the documents incorporated by reference in this prospectus and, if applicable, in any prospectus supplement used in connection with an offering of Debt Securities, before making an investment decision, including those risks identified under “Item IA. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2007, which is incorporated by reference in this prospectus and which may be amended, supplemented or superseded from time to time by other reports that we subsequently file with the SEC. Additional risks, including those that relate to any particular Debt Securities we offer, may be included in a prospectus supplement or free writing prospectus that we authorize from time to time, or that are incorporated by reference into this prospectus or a prospectus supplement.

Our business, financial condition, results of operations and cash flows could be materially adversely affected by any of these risks. The market or trading price of our Debt Securities could decline due to any of these risks. Additional risks not presently known to us or that we currently deem immaterial also may impair our business and operations or cause the price of our Debt Securities to decline.

FORWARD-LOOKING INFORMATION

The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking information. Forward-looking information is based on projections and estimates, not historical information.

RATIO OF EARNINGS TO FIXED CHARGES

We have presented in the table below our historical consolidated ratio of earnings to fixed charges for the periods shown.

	Year Ended December 31,
	2007	2006	2005	2004	2003
Ratio of earnings to fixed charges	11.8	9.7	7.3	4.6	3.8

Our computation of the ratio of earnings to fixed charges includes our consolidated subsidiaries and companies in which we own at least 20% but less than or equal to 50% of the equity. “Earnings” are determined by adding “total fixed charges,” excluding interest capitalized, to earnings before income taxes, eliminating equity in undistributed earnings and adding back losses (or deducting undistributed earnings) of companies in which we own at least 20% but less than or equal to 50% of the equity. “Total fixed charges” consists of interest on all indebtedness (whether expensed or capitalized), amortization of debt discount or premium, capitalized expenses related to indebtedness and an interest factor attributable to rents.

USE OF PROCEEDS

Except as may be described otherwise in a prospectus supplement, we expect to use the net proceeds from the sale of the Debt Securities under this prospectus for general corporate purposes. These purposes may include the repayment of indebtedness, future acquisitions, capital expenditures, working capital and any other corporate purpose. Until we apply the net proceeds for specific purposes, we may invest the net proceeds in cash equivalents or short-term investments.

DESCRIPTION OF DEBT SECURITIES

The following is a general description of the Debt Securities that may be issued from time to time by us under this prospectus. The particular terms relating to each Debt Security will be set forth in a prospectus supplement. In the description of the Debt Securities that follows, “we,” “us” and “our” refer only to Lockheed Martin Corporation and not to any of its subsidiaries.

General

We may issue from time to time one or more series of Debt Securities under an indenture between us and The Bank of New York, as trustee. The indenture will not limit the amount of Debt Securities that we may issue.

The Debt Securities will be our direct, unsecured and unsubordinated obligations, and may be issued either separately or together with, or upon the conversion of, or in exchange for, other securities.

The following description is only a summary of the material provisions of the indenture for the Debt Securities and is qualified by reference to the indenture, a form of which is filed as an exhibit to the registration statement of which this prospectus is a part. We urge you to read the indenture because it, and not this description, define your rights as a holder of the Debt Securities. The summary below of the general terms of the Debt Securities will be supplemented by the more specific terms in the prospectus supplement for a particular series of Debt Securities.

Terms

The indenture provides for the issuance of Debt Securities in one or more series. A prospectus supplement relating to a series of Debt Securities will include specific terms relating to that offering. These terms will include some or all of the following:

• the title of the Debt Securities;

• any limit on the total principal amount of the Debt Securities;

• the price or prices at which we will sell the Debt Securities;

• the maturity date or dates of the Debt Securities;

• the rate or rates, which may be fixed or variable, at which the Debt Securities will bear interest and the date from which such interest will accrue;

• the dates on which interest will be payable and the related record dates;

• whether any index, formula or other method will be used to determine payments of principal or interest and the manner of determining the amount of such payments;

• the place or places of payments on the Debt Securities;

• whether the Debt Securities are redeemable;

• any redemption dates, prices, obligations and restrictions on the Debt Securities;

• any mandatory or optional sinking fund or purchase fund or analogous provisions;

• the denominations in which the Debt Securities will be issued, if other than $1,000 or multiples of $1,000;

• the currency in which principal and interest will be paid, if other than U.S. dollars;

• any provisions granting special rights upon the occurrence of specified events;

• any deletions from, changes in or additions to the events of default or the covenants specified in the indenture;

5

• any trustees, authenticating or paying agents, transfer agents, registrars or other agents for the Debt Securities if other than the trustee;

• any conversion or exchange features of the Debt Securities;

• whether we will issue the Debt Securities as original issue discount securities for federal income tax purposes;

• any special tax implications of the Debt Securities;

• the terms of payment upon acceleration; and

• any other material terms of the Debt Securities.

We may issue Debt Securities that are convertible into or exchangeable for our common stock or other securities of Lockheed Martin or another company. We may also continuously offer Debt Securities in a medium term note program. If we issue these types of Debt Securities, we will provide additional information in a prospectus supplement.

We may sell Debt Securities at a discount below their stated principal amount, bearing no interest or interest at a rate that, at the time of issuance, is different than market rates. When we refer to the principal and interest on Debt Securities, we also mean the payment of any additional amounts that we are required to pay under the indenture or the Debt Securities, including amounts for certain taxes, assessments or other governmental charges imposed on holders of Debt Securities.

Denomination, Form, Payment and Transfer

In general, we will denominate and make payments on Debt Securities in U.S. dollars. If we issue Debt Securities denominated, or with payments, in a foreign or composite currency, a prospectus supplement will specify the currency or composite currency.

We may from time to time issue Debt Securities as registered securities. This means that holders will be entitled to receive certificates representing the Debt Securities registered in their name. You can transfer or exchange Debt Securities in registered form upon reimbursement of any taxes or government charges. This transfer or exchange can be made at the trustee’s corporate trust office or at any other office maintained by us for such purposes. We may charge a reasonable fee in connection with certain transfers and exchanges. If the Debt Securities are in registered form, we can pay interest by check mailed to the person in whose name the Debt Securities are registered on the days specified in the indenture.

As a general rule, however, we will issue Debt Securities in the form of one or more global certificates that will be deposited with The Depository Trust Company, New York, New York (“DTC”). DTC will act as depository for the global certificates. Beneficial interests in global certificates will be shown on, and transfer of beneficial interests will be effected only through, records maintained by DTC and its participants. Therefore, if you wish to own Debt Securities that are represented by one or more global certificates, you can do so only indirectly or “beneficially” through an account with a broker, bank or other financial institution that has an account with DTC (that is, a DTC participant) or through an account directly with DTC if you are a DTC participant.

During the period of time the Debt Securities are represented by one or more global certificates:

• You will not be able to have the Debt Securities registered in your name.

• You will not be able to receive a physical certificate for the Debt Securities.

• DTC will credit interest and principal payments from us to the accounts of your broker, bank or other financial institution according to their beneficial ownership as reflected in DTC’s records.

6

• Our obligations, as well as the obligations of the trustee and any of our agents, under the Debt Securities will run only to DTC as the registered owner of the Debt Securities. For example, once we make payment to DTC, we will have no further responsibility for the payment even if DTC or your broker, bank or other financial institution fails to pass it on so that you receive it.

• Your rights under the Debt Securities relating to payments, transfer, exchanges and other matters will be governed by applicable law and by the contractual arrangements between you and your broker, bank or other financial institution, and the contractual arrangements you have or your broker, bank or financial institution has with DTC. Neither we nor the trustee will have any responsibility for the actions of DTC or your broker, bank or financial institution.

• You may not be able to sell your interests in the Debt Securities to some insurance companies and others who are required by law to own their Debt Securities in the form of physical certificates.

• Because the Debt Securities will trade in DTC’s Same-Day Funds Settlement System, when you buy or sell interests in the Debt Securities, payment for them will have to be made in immediately available funds. This could affect the attractiveness of the Debt Securities to others.

We, the trustee and the paying agent have no responsibility or liability for the records relating to beneficial ownership interests in the global certificates or for the payments of principal and interest for the accounts of beneficial holders of interests in the global certificates. A global certificate generally can be transferred only as a whole, unless it is being transferred to certain nominees of DTC or it is exchanged in whole or in part for Debt Securities in physical form in accordance with the indenture. A series of Debt Securities represented by global certificates will be exchangeable for Debt Securities in registered form with the same terms in authorized denominations if:

• DTC notifies us that it is unwilling or unable to continue as depositary or if DTC ceases to be a clearing agency registered under applicable law and we do not appoint a successor depositary within 90 days; or

• we decide not to require all of the Debt Securities of a series to be represented by global certificates and notify the trustee of that decision.

Events of Default

Unless we indicate otherwise in a prospectus supplement, the following are events of default under the indenture with respect to each series of Debt Securities:

• failure to pay the principal or any premium on any Debt Security of that series when due;

• failure for 30 days to pay interest on any Debt Security of that series when due;

• failure to comply with any other agreement relating to the Debt Securities of that series or in the indenture that continues for 90 days after we have been given written notice of such failure; or

• certain events of bankruptcy, insolvency or reorganization.

An event of default for one series of Debt Securities does not necessarily constitute an event of default for any other series. The trustee may withhold notice to the Debt Securities holders of any default, except a payment default, if it considers such action to be in the holders’ interests.

If an event of default occurs and continues, the trustee, or the holders of at least 25% in aggregate principal amount of the Debt Securities of the series, may declare the entire principal of, and any premium or accrued interest on, all the Debt Securities of that series to be due and payable immediately. If this happens, subject to certain conditions, the holders of a majority of the aggregate principal amount of the Debt Securities of that series can void the acceleration of payment.

7

The indenture provides that the trustee has no obligation to exercise any of its rights at the direction of any holders, unless the holders offer the trustee reasonable indemnity. If they provide this indemnification, the holders of a majority in principal amount of any series of Debt Securities have the right to direct any proceeding, remedy, or power available to the trustee with respect to that series.

Conversion Rights

We will describe the terms upon which Debt Securities may be convertible into our common stock or other securities of Lockheed Martin or another company in a prospectus supplement. These terms will include provisions as to whether conversion is mandatory or optional. They also may include provisions adjusting the number of shares of our common stock or such other securities of Lockheed Martin or another company that are issuable upon any such conversion.

Certain Covenants

Unless the applicable prospectus supplement specifies otherwise, the Debt Securities will be subject to the restrictive covenants described below. Any additional restrictive covenants applicable to a particular series of Debt Securities that we offer will be described in the applicable prospectus supplement. Under the indenture, we will agree to:

• pay the principal, interest and any premium on the Debt Securities when due;

• maintain a place of payment; and

• deliver a report to the trustee at the end of each fiscal year reviewing our obligations under the indenture.

The indenture restricts our ability and the ability of certain of our subsidiaries to encumber assets that are defined in the indenture as restricted property. If we, or any restricted subsidiary, as defined below, pledge or mortgage any of our restricted property to secure any debt, then we will, unless an exception applies, pledge or mortgage the same property to or for the benefit of the trustee to secure the Debt Securities equally and ratably for as long as such debt is secured by such property.

This restriction will not apply in certain situations. Assets may be encumbered if the encumbrance is a permitted lien, as defined below, without regard to the amount of debt secured by the encumbrance. Assets also may be encumbered if the sum of the following does not exceed 10% of our consolidated net tangible assets:

• the amount of debt secured by such assets, plus

• the total amount of other secured debt on restricted property, excluding debt that is secured by a permitted lien and excluding debt secured by a lien existing on the date of the indenture, plus

• the total amount of attributable debt in respect of certain sale-leaseback transactions.

Permitted liens include:

• liens on a corporation’s property, stock or debt at the time it becomes a restricted subsidiary;

• liens on property at the time we or a restricted subsidiary acquires the property, provided that no such lien extends to any of our other property or any other property of a restricted subsidiary;

• liens securing payment of a property’s purchase price or to secure debt incurred within one year after the property’s acquisition for the purpose of financing the purchase price;

• liens securing debt owing by a restricted subsidiary to us or another restricted subsidiary;

• liens on property of an entity at the time such entity is merged into or consolidated with us or a restricted subsidiary or at the time we or a restricted subsidiary acquire all or substantially all of the assets of the entity;

8

• liens in favor of any customer to secure payments or performance pursuant to any contract or statute, any related indebtedness, or debt guaranteed by a government or governmental authority;

• liens arising pursuant to any order of attachment, distraint or similar legal process so long as the execution or other enforcement is effectively stayed and the claims secured are being contested in good faith by appropriate proceedings;

• materialmen’s, suppliers’, tax or similar liens arising in the ordinary course of business for sums not overdue or which are being contested in good faith by appropriate proceedings; and

• any renewal, extension or replacement for any lien permitted by one of the exceptions described above or a lien existing on the date that Debt Securities of a series are first issued, provided that the renewal, extension, or replacement is limited to all or any part of the same property subject to the existing lien.

Except in certain circumstances, the indenture also restricts our ability and the abilities of certain of our subsidiaries to enter into sale-leaseback transactions. The indenture will not otherwise limit our ability to incur additional debt, unless we tell you this in a prospectus supplement.

The following are summaries of definitions for certain terms we have just used. For the full definition of these terms, you should refer to the form of the indenture filed as an exhibit to the registration statement.

• Attributable debt for a lease means the carrying value of the capitalized rental obligation determined under generally accepted accounting principles.

• Consolidated net tangible assets means our total assets, including the assets of our consolidated subsidiaries, as reflected in our most recent balance sheet, less current liabilities, goodwill, patents and trademarks.

• Principal property means, with certain exceptions, any manufacturing facility located in the United States and owned by us or by one or more restricted subsidiaries and which has, as of the date the lien is incurred, a net book value, after deduction of depreciation and similar charges, greater than 3% of consolidated net tangible assets, or any manufacturing facility or other property declared to be a principal property by our chief executive officer or chief financial officer by delivery of a certificate to that effect to the trustee.

• Restricted property means, as to any particular series of Debt Securities, any principal property, any debt of a restricted subsidiary owned by us or one of our restricted subsidiaries on the date Debt Securities of the series are first issued or secured by a principal property or any shares of our stock or the stock of a restricted subsidiary owned by us or one of our restricted subsidiaries.

• Restricted subsidiary means one of our subsidiaries that has substantially all of its assets located in, or carries on substantially all of its business in, the United States and that owns a principal property, except that a subsidiary shall not be a restricted subsidiary if its shares are registered with the SEC or if it is required to file periodic reports with the SEC.

• Sale-leaseback transaction means, subject to certain exceptions, an arrangement pursuant to which we, or a restricted subsidiary, transfer a principal property to a person and contemporaneously lease it back from that person.

Consolidation, Merger or Sale

The indenture prohibits us from consolidating with or merging into another corporation, or transferring all or substantially all of our assets to another corporation unless:

• the successor corporation (which need not be a U.S. corporation) assumes all of our obligations under the Debt Securities and the indenture;

• immediately after giving effect to the transaction, no event of default and no circumstances which, after notice or lapse of time or both, would become an event of default, shall have happened and be continuing; and

9

• we have delivered to the trustee an officers’ certificate and a legal opinion confirming that we have complied with the indenture.

If we enter into such a transaction and comply with these provisions, our obligations under the Debt Securities and the indenture will terminate.

Redemption, Sinking Fund and Defeasance

If a series of Debt Securities may be redeemed or is subject to a sinking fund, the prospectus supplement will describe those terms.

The indenture permits us to discharge or defease certain of our obligations for any series of Debt Securities at any time. We may defease a series of Debt Securities by depositing with the trustee cash or government securities sufficient to pay all sums due on that series. Under certain circumstances, if we defease a series of Debt Securities, our legal obligation to pay principal, interest and any premium on that series will be discharged. We can defease one series of Debt Securities without defeasing any other series.

Under U.S. federal income tax law, a discharge of our obligation to pay principal, interest and any premium on the Debt Securities would be treated as an exchange of the Debt Securities for a new security representing an interest in the trust. Each holder would be required to recognize a gain or loss equal to any difference between the holder’s cost or other tax basis for the Debt Securities and the value of the holder’s interest in the trust. Holders would not be required to recognize a gain or loss under U.S. federal income tax law in the event of a defeasance of certain contractual obligations without a discharge of our legal obligation to pay principal, interest and any premium on the Debt Securities. Prospective investors are urged to consult their own tax advisers as to the consequences of a discharge, including the applicability and effect of tax laws other than U.S. federal income tax law.

Changes to the Indenture

Holders who own more than 50% in principal amount of the Debt Securities of a series can agree with us to change the provisions of the indenture relating to that series. However, no change can affect the payment terms or the percentage required to change other terms without the consent of all holders of Debt Securities of the affected series.

We may enter into supplemental indentures for other specified purposes and to make changes that would not materially adversely affect your interests, including the creation of any new series of Debt Securities, without the consent of any holder of Debt Securities.

10

PLAN OF DISTRIBUTION

We may sell Debt Securities to or through underwriters and also may sell Debt Securities directly to other purchasers or through agents.

The distribution of the Debt Securities offered under the prospectus may occur from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

In connection with the sale of Debt Securities, underwriters may receive compensation from us or from purchasers of Debt Securities for whom they may act as agents in the form of discounts, concessions or commissions.

Underwriters may sell Debt Securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of Debt Securities offered under the prospectus may be “underwriters” as defined in the Securities Act. Any underwriters or agents will be identified and their compensation (including underwriting discount) will be described in the applicable prospectus supplement. The prospectus supplement will also describe the other terms of the offering, including any discounts or concessions allowed or re-allowed or paid to dealers and any securities exchanges on which the offered securities may be listed.

We may have agreements with the underwriters, dealers and agents to indemnify them against certain liabilities, including certain liabilities under the Securities Act, or to contribute with respect to payments which the underwriters, dealers or agents may be required to make as a result of those liabilities.

If the applicable prospectus supplement indicates, we may authorize dealers or agents to solicit offers by certain institutions to purchase Debt Securities from us pursuant to contracts that provide for payment and delivery on a future date. We must approve all institutions, but they may include, among others:

• commercial and savings banks;

• insurance companies;

• pension funds;

• investment companies; and

• educational and charitable institutions.

An institutional purchaser’s obligation under the contract will be subject to the condition that the purchase of the offered Debt Securities at the time of delivery is allowed by the laws that govern such purchaser. The dealers and the agents will not be responsible for the validity or performance of the contracts.

11
