DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

       This prospectus contains forward-looking statements. For example, statements that relate to our expectations regarding projected earning levels, market outlook, new awards, backlog levels, competition, the adequacy of funds to service debt and the implementation of new strategic initiatives are forward looking in nature. These forward-looking statements reflect our current analysis of existing information, although no assurance can be given that such statements will be realized. Due to unknown risks, our actual results may differ materially from our expectations or projections. As a result, caution must be exercised in relying on forward-looking statements. The factors potentially contributing to such differences include, among others:

Table of Contents

      The forward-looking statements are also based on various operating assumptions regarding, among other matters, overhead costs and employment levels that may not be realized. In addition, while most risks affect only future costs or revenues that we anticipate we will receive, some risks may relate to accruals that have already been reflected in earnings. Our failure to receive payments of these accrued earnings could result in charges against future earnings.

      Additional information concerning factors that may influence our results can be found in press releases and periodic filings with the Securities and Exchange Commission including the risk factors set forth in the section captioned “Company Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2001. These filings are available publicly and upon request from Fluor’s Investor Relations Department: (949) 349-3909. We disclaim any intent or obligation to update forward-looking statements.

THE COMPANY

       Fluor Corporation is a leading professional services company offering a diverse range of value-added, knowledge-based services from traditional engineering, procurement and construction services to total asset management. Fluor Corporation is basically a holding company which owns, directly or indirectly, the stock of numerous subsidiary corporations. Fluor Corporation is aligned into five principal operating segments:

      Fluor Constructors International, Inc., which is organized and operates separately from our operating segments, provides unionized management, construction and management services in the United States and Canada, both independently and as a subcontractor, on projects to our operating segments.

      On November 30, 2000, Fluor Corporation completed a reverse spin-off transaction in which its coal segment, previously operated under its A. T. Massey Coal Company, Inc. subsidiary, was separated from the other business segments of Fluor Corporation.

      Fluor Corporation was incorporated in Delaware on September 11, 2000. Fluor Corporation’s principal executive offices are located at One Enterprise Drive, Aliso Viejo, California 92656, telephone number (949) 349-2000.

       Except as otherwise specified in a prospectus supplement, we will use the net proceeds from the sale of the debt securities for general corporate purposes including working capital, capital expenditures, stock purchase programs, repayment and refinancing of debt and acquisitions. We may invest funds not required immediately for such purposes in marketable securities and short-term investments.

RATIO OF EARNINGS TO FIXED CHARGES

      Our ratios of earnings to fixed charges for each of the four years ended October 31, 2000, the year ended December 31, 2001 and the three months ended March 31, 2002 are as follows:

      For purposes of computing the ratios of earnings to fixed charges, “earnings” consist of earnings from continuing operations before provision for income taxes plus fixed charges less equity in earnings from less than 50% owned persons, net of distributions. “Fixed charges” consist of interest and approximately one-third of rental expense. Please also refer to the section captioned “Results of Operations” contained in our Annual Report on Form 10-K for the year ended December 31, 2001 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2002 for a discussion of factors which have affected our earnings from continuing operations before income taxes.

       The debt securities covered by this prospectus will be our direct unsecured obligations. The debt securities will be issued in one or more series under an indenture, between us and The Bank of New York, as trustee. Because we are a holding company, however, our ability to meet our debt obligations depends upon the earnings of, and dividends and other payments from, our subsidiaries. Furthermore, the debt securities offered hereby will be effectively subordinated to all existing and future liabilities of our subsidiaries. This means that upon the liquidation, reorganization or insolvency of any of our subsidiaries, the claims of creditors and any preferred stockholders will generally take priority over our right to participate as a stockholder in any distribution of the assets of such subsidiary.

      This prospectus briefly outlines the material provisions of the indenture. A copy of the form of indenture has been filed as an exhibit to the registration statement. Although this prospectus and the applicable prospectus supplement provide all the information that we believe is material with respect to the debt securities, you should read the indenture for provisions that may be important to you. In the summary below, we have included references to section numbers of the indenture so that you can easily locate these provisions.

General

      The debt securities will rank equally with all of our other unsecured and unsubordinated debt. The indenture does not limit the amount of debt we may issue under the indenture or otherwise. We may issue the debt securities in one or more series with the same or various maturities, at par or a premium, or with original issue discount.

      The debt securities may be issuable in the form of one or more global securities, as further described under the caption “Global Securities” below. Except for any debt securities issued in the form of a global security, the debt securities are exchangeable or transferable without charge. We may, however, require you to pay us for any tax or other governmental charge payable in connection with the transfer and exchange and may also require you to furnish appropriate endorsements and transfer documents. (Section 3.05)

6

Table of Contents

      Unless otherwise specified in a prospectus supplement, any principal, premium or interest payment will be payable, and the transfer of debt securities will be registrable, at the principal corporate trust office of the Trustee. In addition, unless otherwise specified in a prospectus supplement and except in the case of any debt securities issued in the form of a global security, we may opt to make interest payments by check, mailed to the address of the person entitled to receive the interest payment as reflected on the security register. (Sections 3.01, 3.05, 10.01 and 10.02)

      The prospectus supplement relating to any series of debt securities being offered will include all additional material terms of the offering not otherwise contained in this prospectus. These terms will include some or all of the following:

7

Table of Contents

(Section 3.01)

      The debt securities may be issued with original issue discount, which means that the debt securities may be sold at a discount below their principal amount. Even if debt securities are not issued at a discount below their principal amount, the debt securities may, for United States Federal income tax purposes, be deemed to have been issued with original issue discount because of their interest payment characteristics. United States Federal income tax and other considerations applicable to debt securities issued with original issue discount will be described in the prospectus supplement relating to those debt securities. In addition, United States Federal tax considerations or other terms or restrictions applicable to debt securities which are denominated in a currency other than United States dollars will be described in the prospectus supplement relating to those debt securities.

Consolidation, Merger or Sale

      We have agreed not to consolidate with or merge with or into any other entity or convey, transfer or lease substantially all of our properties and assets to any person, unless:

(Section 8.01)

      The successor entity would succeed to and would be able to exercise every right and power that we possess under the indenture. Except in the case of a lease of substantially

Modification of Indenture

      There are three categories of changes that we can make to the indenture and the debt securities. First, there are changes that cannot be made to the debt securities without the approval of each holder of debt securities affected by the change. Second, there are changes that can be made with the approval of holders of debt securities owning a majority in aggregate principal amount of the outstanding debt securities of all series affected by the change (voting as one class). All other changes may be made by us without the consent or vote of holders of the debt securities.

      The following is a summary of the changes that cannot be made without the approval of each holder of debt securities affected by the change:

(Section 9.02)

      Holders of debt securities owning a majority in aggregate principal amount of the outstanding debt securities of all series affected by a change (voting as one class) may, on behalf of the holders of all debt securities of the series, waive:

      In determining whether the holders of the requisite aggregate principal amount of the outstanding debt securities have given, made or taken any request, demand, authorization, direction, notice, consent, waiver or other action,

Table of Contents

(Section 1.02)

Events of Default

      The following will be “Events of Default” under the indenture with respect to the debt securities of any series, unless otherwise specified in a prospectus supplement:

(Section 5.01)

      If an Event of Default exists with respect to any series of debt securities, then either 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 amount of all the debt securities of that series immediately due and payable. If the Event of Default involves events in bankruptcy, insolvency or reorganization (as described in clause (5) in the paragraph above), then the principal amount of all the debt securities of that series will automatically, and without any declaration or other action on the part of the Trustee or any holder, become immediately due and payable. If any debt securities of a series are issued with original issue discount, the amount of the debt securities that will become immediately due and payable in an Event of Default will be the portion of the principal amount specified by the terms of the debt securities. At any time after the Trustee or the

10

Table of Contents

      Subject to the provisions of the Trust Indenture Act, the indenture provides that the Trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with the holders’ request or direction. (Sections 6.01 and 6.03) What will be deemed to constitute reasonable indemnity may vary depending on what rights or powers the holders have requested or directed the Trustee to exercise. Subject to the Trustee’s right to indemnification, the holders of a majority in aggregate principal amount of the debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, with respect to the debt securities of that series. (Section 5.12)

      We are required to furnish to the Trustee an annual statement by our officers as to whether we have defaulted in the performance of our obligations under the indenture. In the event that we are in default, we are required to specify the nature and status of the default. (Section 10.04)

      The right of any holder to receive principal, any premium and interest payments on the debt securities or to institute suit for the enforcement of such payment cannot be impaired without that holder’s consent. (Section 5.08)

Conversion Rights

      We may issue debt securities that are convertible into our common stock or other securities or property. The specific terms on which the debt securities are convertible will be described in an applicable prospectus supplement. The terms will include provisions as to whether conversion is mandatory or optional and may include provisions that establish the amount of securities or property that you will receive according to a formula based upon the market price of the securities or property at a particular time.

Global Securities

      We may issue some or all of the debt securities of a series in the form of one or more global securities. Global securities will be deposited with a depository identified in the applicable prospectus supplement. A global security is a security, typically held by a depository, that represents the beneficial interests of a number of purchasers of the security. The specific terms of the depositary arrangement with respect to a series of debt securities will be described in an applicable prospectus supplement.

Defeasance

      The following provisions relating to defeasance and discharge of indebtedness, or relating to defeasance of covenants in the indenture, will apply to the debt securities of any series, or to any specified part of a series, unless otherwise specified in a prospectus supplement. (Section 13.01)

      Defeasance and Discharge. We may discharge all of our obligations with respect to the debt securities by depositing in trust, for the benefit of the holders of the debt securities, money or U.S. government obligations, or both, which will provide a sufficient

11

Table of Contents

      Defeasance of Covenants. Under some circumstances, we may not be required to comply with the restrictive covenants that may be described in this prospectus or any applicable prospectus supplement. In addition, under some circumstances, the occurrence of some Events of Default, including any that may be described in an applicable prospectus supplement, will be deemed not to be or result in an Event of Default. In order for this to occur, we must deposit in trust, for the benefit of the holders of debt securities, money or U.S. government obligations, or both, which will provide a sufficient amount of money to pay any installment of principal, premium or interest payment and any mandatory sinking fund payment required by the debt securities on the designated payment dates. There must also have been, among other things, a United States Internal Revenue Service ruling, or a change in tax law, to the effect that holders of debt securities will be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge were not to occur.

      In the event we exercised this option with respect to any debt securities and the debt securities were accelerated and declared due and payable as a result of an Event of Default, the amount of money and U.S. government obligations deposited in trust may not be sufficient to pay amounts due on the debt securities at the time of the acceleration. In that case, we would remain liable for any amounts still due. (Sections 13.03 and 13.04)

      Acceptable U.S. government obligations are limited under the indenture to:

Table of Contents

Concerning the Trustee

      Upon the occurrence of an Event of Default or an event which, after notice or lapse of time or both, would become an Event or Default, the Trustee may be deemed to have a conflicting interest with respect to the debt securities for purposes of the Trust Indenture Act. In that event, unless the Trustee is able to eliminate the conflicting interest, the Trustee may be required to resign as Trustee under the indenture. If the Trustee resigns, we will be required to appoint a successor Trustee for the indenture.

Governing Law

      The debt securities and the indenture will be governed by, and construed in accordance with, the laws of the State of New York.

PLAN OF DISTRIBUTION

       We may sell debt securities from time to time in one or more transactions. We may sell debt securities (a) through underwriters or dealers; (b) through agents; or (c) directly to one or more purchasers.

Sale Through Underwriters

      If we use underwriters in the sale, the underwriters will acquire the debt securities for their own account. The underwriters may resell the debt securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the debt securities will be subject to conditions. The underwriters will be obligated to purchase all the debt securities of a series offered by a prospectus supplement if any of such debt securities are purchased. The 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. The underwriters may change from time to time any initial public offering price and any discounts, concessions or commissions allowed or re-allowed or paid to dealers.

Sale Through Agents

      We may sell debt securities through agents designated by us. Unless indicated in the prospectus supplement, the agents have agreed to use their reasonable best efforts to solicit purchases for the period of their appointment.

Direct Sales

      We also may sell debt securities directly to purchasers without the involvement of underwriters or agents.

General Information

      We may authorize agents, underwriters or dealers to solicit offers by institutional investors to purchase debt securities providing for payment and delivery on a future date specified in the prospectus supplement. Institutional investors to which such offers may be made, when authorized, include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions that are approved by us. The obligations of any purchasers under delayed delivery and payment arrangements will not be subject to any conditions except that

13

Table of Contents

      Underwriters, dealers and agents that participate in the distribution of the offered securities may be underwriters as defined in the Securities Act of 1933, and any discounts or commissions received by them from us and any profit on the resale of the debt securities by them may be treated as underwriting discounts and commissions under the Securities Act of 1933. We will identify any underwriters or agents, and describe their compensation, in a prospectus supplement.

      The debt securities may or may not be listed on a national securities exchange or a foreign securities exchange. The debt securities will be a new issue of securities with no established trading market. Any underwriters or agents to or through whom we sell debt securities for public offering and sale may make a market in the debt securities. However, the underwriters and agents will not be obligated to make a market in the debt securities and may discontinue their market-making activities at any time without notice. We cannot provide any assurance with respect to the liquidity of the trading market for any of the debt securities.

      We may have agreements with the underwriters, dealers and agents to indemnify them against civil liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments which the underwriters, dealers or agents may be required to make.

      Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of their businesses.

LEGAL MATTERS

       Gibson, Dunn & Crutcher LLP, our outside legal counsel, will issue an opinion about the legality of the debt securities for us. Any underwriters will be advised about other issues relating to any offering of debt securities by their own legal counsel.

EXPERTS

       Ernst & Young LLP, independent auditors, have audited our consolidated financial statements incorporated by reference in our Annual Report on Form 10-K for the year ended December 31, 2001, as set forth in their report, which is incorporated herein by reference. Our financial statements are incorporated by reference in reliance on Ernst & Young LLP’s report, given on their authority as experts in accounting and auditing.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

Item 15. Indemnification of Directors and Officers

      Our Amended and Restated Certificate of Incorporation requires that our directors and officers be indemnified to the maximum extent permitted by Delaware law.

      The General Corporation Law of the State of Delaware provides in general that a director or officer of a corporation (i) shall be indemnified by the corporation for all expenses of litigation or other legal proceedings when he is successful on the merits, (ii) may be indemnified by the corporation for the expenses, judgments, fines and amounts paid in settlement of such litigation (other than a derivative suit) even if he is not successful on the merits if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation (and, in the case of a criminal proceeding, had no reasonable cause to believe his conduct was unlawful), and (iii) may be indemnified by the corporation for expenses of a derivative suit (a suit by a stockholder alleging a breach by a director or officer of a duty owed to the corporation), even if he is not successful on the merits, if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, provided that no such indemnification may be made in accordance with this clause (iii) if the director or officer is adjudged liable to the corporation, unless a court determines that, despite such adjudication but in view of all of the circumstances, he is entitled to indemnification of such expenses. The indemnification described in clauses (ii) and (iii) above shall be made only upon order by a court or a determination by (a) a majority of a quorum of disinterested directors, (b) under certain circumstances, independent legal counsel or (c) the stockholders, that indemnification is proper because the applicable standard of conduct is met. Expenses incurred by a director or officer in defending an action may be advanced by the corporation prior to the final disposition of such action upon receipt of an undertaking by such director or officer to repay such expenses if it is ultimately determined that he is not entitled to be indemnified in connection with the proceeding to which the expenses related.

      Our Amended and Restated Certificate of Incorporation includes a provision eliminating, to the fullest extent permitted by Delaware law, director liability for monetary damages for breaches of fiduciary duty.

Item 16. Exhibits

Item 17. Undertakings

A. Undertaking Pursuant to Rule 415

      We hereby undertake:

      (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

provided, however, that paragraphs A(l)(a) and A(l)(b) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by us pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”) that are incorporated by reference in the Registration Statement.

      (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-2

Table of Contents

      (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. Undertaking Regarding Filings Incorporating Subsequent Exchange Act Documents by Reference

      We hereby undertake that, for purposes of determining any liability under the Securities Act, each filing of our annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed the initial bona fide offering thereof.

C. Undertaking in Respect of Indemnification

      Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of our counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by us is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

D. Undertaking Regarding Rule 430A Under the Securities Act

      We hereby undertake that:

      (1) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of the Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by us pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of the Registration Statement as of the time it was declared effective.

      (2) For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
