Under this shelf process, we may issue, from time to time, up to 50,000,000 shares of our common stock in connection with acquisitions of other businesses or assets. Each time we issue common stock under the registration statement we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with the additional information described under the heading "Where You Can Find More Information." SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS In this prospectus and in the documents we incorporate by reference, we state our views about our future performance. These views, which constitute "forward-looking statements" under the Private Securities Litigation Reform Act of 1995, involve risks and uncertainties that are difficult to predict and, accordingly, our actual results may differ materially from the results discussed in such forward- looking statements. The Company has no obligation to update any forward-looking statements as a result of new information, future events or otherwise. Factors that affect our results of operations include the levels of home improvement and residential construction activity principally in North America and Europe (including repair and remodeling and new construction), our ability to effectively manage our overall cost structure, fluctuations in European currencies (primarily the euro and British pound), the importance of and our relationships with home centers (including The Home Depot, which represented approximately 25 percent of our sales in 2001) as distributors of home improvement and building products, and our ability to maintain our leadership positions in our markets in the face of increasing global competition. Historically, we have been able to largely offset cyclical declines in housing markets through new product introductions and acquisitions as well as market share gains. Additional factors that may significantly affect our performance are discussed under "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K and in our Quarterly Reports on Form 10-Q that are on file with the SEC as well as under the heading "Risk Factors" in this prospectus. YOU SHOULD RELY ONLY ON THE INFORMATION CONTAINED IN THIS PROSPECTUS, IN THE ACCOMPANYING PROSPECTUS SUPPLEMENT AND IN MATERIAL WE FILE WITH THE SEC. WE HAVE NOT AUTHORIZED ANYONE TO PROVIDE YOU WITH INFORMATION THAT IS DIFFERENT. WE ARE OFFERING TO SELL, AND SEEKING OFFERS TO BUY, THE SECURITIES DESCRIBED IN THIS PROSPECTUS ONLY WHERE OFFERS AND SALES ARE PERMITTED. SINCE INFORMATION THAT WE FILE WITH THE SEC IN THE FUTURE WILL AUTOMATICALLY 2 UPDATE AND SUPERSEDE INFORMATION CONTAINED IN THIS PROSPECTUS OR ANY ACCOMPANYING PROSPECTUS SUPPLEMENT, YOU SHOULD NOT ASSUME THAT THE INFORMATION CONTAINED IN THIS PROSPECTUS OR IN ANY PROSPECTUS SUPPLEMENT IS ACCURATE AS OF ANY DATE OTHER THAN THE DATE ON THE FRONT OF THE DOCUMENT. MASCO CORPORATION Masco Corporation manufactures, sells and installs home improvement and building products, with emphasis on brand name products and services holding leadership positions in their markets. Masco is among the largest manufacturers in North America of brand name consumer products designed for the home improvement and home construction markets. Our business segments are: cabinets and related products; plumbing products; installation and other services; decorative architectural products and other specialty products. Our executive offices are located at 21001 Van Born Road, Taylor, Michigan 48180. Our telephone number is (313) 274-7400 and our website address is http://www.masco.com. The information on our website is not part of this prospectus. Except as the context otherwise indicates, the terms "Masco," "we," "us," and "our" refer to Masco Corporation. RISK FACTORS Before purchasing these securities, you should consider all of the information set forth in this prospectus, in any accompanying prospectus supplement and the information incorporated by reference in this prospectus and, in particular, you should take into account the risk factors set forth below. WE CANNOT ASSURE YOU THAT OUR GROWTH STRATEGIES WILL BE SUCCESSFUL Mergers and acquisitions have historically contributed significantly to our long-term growth, after the initial impact on earnings of transaction-related costs and expenses such as interest and added depreciation and amortization. Successful strategic acquisitions require the integration of operations and management and other efforts to realize the benefits that may be available to us following the acquisition. Although we believe that we have been successful in doing so in the past, we can give no assurance that we will continue to be able to identify, acquire and integrate successful strategic acquisitions in the future or be able to implement successfully our operating and growth strategies within our existing markets or with respect to any future product or geographic diversification efforts. OUR BUSINESS HAS BEEN AFFECTED BY ECONOMIC WEAKNESS AND BUSINESS CONDITIONS Factors that affect our results of operations include the levels of home improvement and residential construction activity, principally in North America and Europe (including repair and remodeling and new construction), our ability to effectively manage our overall cost structure, fluctuations in European currencies (primarily the euro and British pound), and our ability to maintain our leadership positions in our markets in the face of increasing global competition. Historically, we have been able largely to offset cyclical declines in housing markets through new product introductions and acquisitions as well as market share gains. We can give no assurance that we will be able to offset these cyclical declines in the future. WE RELY ON OUR KEY CUSTOMERS Our relationships with home centers are important to us. Direct sales of our product lines to home center retailers have increased substantially in recent years and, in 2001, sales to our largest customer, The Home Depot, were $2.1 billion (approximately 25 percent of total sales). Although builders, dealers and other retailers represent other channels of distribution for our products, we believe that the loss of a substantial portion of our sales to The Home Depot would have a material adverse impact on our company. 3 WE ARE DEFENDANTS IN LITIGATION INVOLVING PRODUCTS OF OUR BEHR PROCESS CORPORATION SUBSIDIARY We and our Behr Process Corporation subsidiary are defendants in several class action lawsuits, including a class action lawsuit in the State of Washington against Behr. These lawsuits related to certain of Behr's previously manufactured exterior wood coating products. None of the complaints set forth any specific amount of damages. On October 29, 2002, we announced preliminary settlements to resolve all of these class actions pending in the United States under which all claims relating to the products would be dismissed without any admission of liability or wrongdoing following final court approval of the settlements. Preliminary settlement agreements have been reached; the aggregate cost of which we estimate will be in a range of $166 million to $206 million. The Company has concluded that no amount within that range is more likely than any other, and therefore has recorded $166 million as a liability in the third quarter 2002 consolidated financial statements related to these settlements. The Company is currently negotiating its liability insurers' contribution to the cost of the settlements. However, no insurance amounts have been recorded as of November 30, 2002. Recoveries from liability insurers or other third parties will be recorded at such time as they are agreed to, or otherwise received. Management believes that the settlements described above will receive final approval without substantial changes, although there can be no assurance in that regard. Management believes that the Company will not incur additional material losses with regard to this matter. These proceedings and any recent developments concerning this litigation are more fully described in our periodic and other reports filed with the SEC and incorporated by reference into the registration statement of which this prospectus forms a part. OUR INTERNATIONAL BUSINESS HAS SPECIAL RISKS Our international operations outside of North America, principally in Europe, are subject to political, monetary, economic and other risks attendant generally to international businesses. These risks generally vary from country to country. Results of existing European operations have been adversely influenced in recent years, in part due to softness in our European markets, competitive pricing pressures on certain products, the effect of a higher percentage of lower margin sales to total European sales and a stronger U.S. dollar. OUR MARKETS ARE HIGHLY COMPETITIVE The major markets for our products are highly competitive. Competition in all of our product lines is based primarily on performance, quality, style, delivery, customer service and price, with the relative importance of such factors varying among product categories. WE HAVE FINANCIAL COMMITMENTS AND INVESTMENTS IN FINANCIAL ASSETS As part of our acquisition strategy we often structure acquisition and other transactions to provide, in addition to the consideration paid at closing, contingent consideration to be paid in cash or stock if specified conditions are met. These conditions may include the operating performance of the acquired business in the case of an acquisition, the price of our common stock, or both. In addition to possibly increasing the consideration we ultimately pay for an acquisition, these conditions may also affect the number of contingently issuable shares that are included in our periodic computation of diluted earnings per common share, the amount of our accrued liabilities and our results of operations. We also maintain investments in a number of private equity funds and in marketable securities. These investments are generally carried as long-term assets on our balance sheet. We record investments in marketable securities at fair value, which is subject to adjustment based on market fluctuations. Unrealized losses that are temporary impairments and unrealized gains are recognized, net of taxes, through shareholders' equity as a component of other comprehensive income. Realized gains and losses and charges for other-than-temporary impairments are included in other income. Our investments in private equity funds have no readily ascertainable market value. These equity funds may invest in transactions that have an above average degree of financial leverage or business risk. Our investments in 4 these funds are carried at cost and are periodically evaluated for impairment or when circumstances indicate an impairment may exist. Income and gains, net realized from these investments are included in other income when distributed or received. In addition, we have commitments that may require us to contribute additional capital to these private equity funds. USE OF PROCEEDS This prospectus relates to shares of common stock that may be offered and issued by us from time to time in connection with acquisitions of other businesses or assets. Other than the businesses or assets acquired, there will be no proceeds to us from these offerings.

For more information as to how you can obtain a current copy of our amended and restated certificate of incorporation, see "Where You Can Find More Information." Our amended and restated certificate of incorporation authorizes the issuance of one million shares of preferred stock, par value $1.00 per share and 1.4 billion shares of common stock, par value $1.00 per share. PREFERRED STOCK We may issue preferred stock from time to time in one or more series, without stockholder approval. Subject to limitations prescribed by law, our board of directors is authorized to determine the voting powers, if any, designations and powers, preferences and rights, and the qualifications, limitations or restrictions thereof, for each series of preferred stock that may be issued and to fix the number of shares of each series of preferred stock. As of September 30, 2002, there were approximately 16,700 shares of series B convertible preferred stock outstanding. These preferred shares are convertible into approximately 16,700,000 shares of common stock, subject to adjustment. Each share of series B preferred stock is entitled to receive the same dividends as, and in general has voting rights equivalent to those of, the shares of common stock into which such preferred stock is convertible. Shares of series B preferred stock vote as a class as required by Delaware law and are subject to certain restrictions on transfer. COMMON STOCK Holders of common stock are entitled to one vote per share on matters to be voted on by our stockholders and, subject to the rights of the holders of any preferred stock of Masco then outstanding, to receive dividends, if any, when declared by our board of directors in its discretion out of legally available funds. Upon any liquidation or dissolution of Masco, holders of common stock are entitled to receive pro rata all assets remaining after payment of all liabilities and liquidation of any shares of any preferred stock at the time outstanding. Holders of common stock have no preemptive or other subscription rights, and there are no conversion rights or redemption or sinking fund provisions with respect to common stock. As of September 30, 2002, there were approximately 493,240,000 shares of our common stock outstanding and approximately 20,601,000 shares reserved for issuance upon exercise of outstanding stock options. All of our outstanding common stock is fully paid and non-assessable and all of the shares of common stock that may be offered with this prospectus will be fully paid and non-assessable. The transfer agent and registrar for our common stock is The Bank of New York, New York, New York. STOCKHOLDER RIGHTS AGREEMENT We have a stockholder rights agreement which provides that each share of our outstanding common stock has one-half of one right to purchase one one-thousandth of a share of preferred stock. The purchase price per one one-thousandth of a preferred share under the stockholder rights agreement is $100. Our board of directors may, at its option, redeem all of the outstanding rights at a redemption price of $0.01 per right, subject to adjustment, prior to the time that an acquiring person obtains 15% or more of our outstanding common stock. The rights will expire on December 6, 2005 unless earlier redeemed or exchanged by us. The rights under our stockholder rights agreement are evidenced by the outstanding certificates representing our common stock but will be represented by separate certificates approximately 10 days after someone, other than we or any of our subsidiaries or employee benefit plans, acquires at least 15% of our outstanding common stock, or approximately 10 days after someone commences a tender offer that would result in that person owning at least 15% of our outstanding common stock. If an acquiring person obtains or has the right to obtain at least 15% of our outstanding common stock, then each right will entitle the holder to purchase for $100 either a number of shares of our common stock having a then 6 current market value of $200 or a number of shares of common stock of the acquiring person having a then current market value of $200. After an acquiring person obtains 15% or more, but less than 50%, of our outstanding common stock, our board of directors may, at its option, exchange all or part of the then outstanding and exercisable rights for shares of our common stock, at an exchange ratio of two shares of common stock per right. Any rights obtained by a person acquiring at least 15% of our outstanding common stock will be null and void. Our stockholder rights agreement has anti-takeover effects. The rights may cause substantial dilution to a person or group that attempts to acquire us without conditioning the offer on a substantial number of rights being acquired, redeemed or declared invalid. Accordingly, the existence of the rights may deter acquirors from making takeover proposals or tender offers. However, the rights are not intended to prevent a takeover, but rather are designed to enhance the ability of our board of directors to negotiate with an acquiror on behalf of all of the stockholders. In addition, the rights should not interfere with a proxy contest. OFFERED SECURITIES We propose to issue and sell the shares of common stock offered by this prospectus in connection with acquisitions of other businesses or assets. The shares of common stock will be offered on terms to be determined at the time of sale. Shares of common stock may be issued in exchange for shares of capital stock, partnership interests or other assets representing an interest, direct or indirect, in other entities, in exchange for assets used in or related to the business of these entities or otherwise pursuant to acquisition agreements. The consideration for these acquisitions may consist of common stock, cash, assumption of liabilities, or a combination of these and other forms of consideration. The terms of any acquisition and of the issuance of any shares of common stock in connection with an acquisition will generally be determined by direct negotiations with the owners of the business or assets to be acquired or, in the case of entities which are more widely held, through exchange offers to stockholders or documents soliciting the approval of statutory mergers, consolidations or sales of assets. Underwriting discounts or commissions will generally not be paid by us. However, in some situations, we may issue shares of common stock covered by this prospectus to pay brokers' commissions incurred in connection with acquisitions. For a description of our common stock, see "Description of Capital Stock." This prospectus, as amended or supplemented if appropriate, has also been prepared for use by prospective selling stockholders who receive shares of common stock in acquisitions, including shares received under this prospectus; provided, however, that no selling stockholder is authorized to use this prospectus to reoffer any shares of common stock without first obtaining our prior written consent. Resales may be made in the manner described in this prospectus, as amended or supplemented, in the manner permitted by Rule 145(d) under the Securities Act or under an exemption from the Securities Act. Profits realized on resales by selling stockholders may be regarded as underwriting compensation under the Securities Act. Resales by selling stockholders may be made directly to investors or through a securities firm acting as an underwriter, broker or dealer. When resales are to be made through a securities firm, that securities firm may be engaged to act as the selling stockholder's agent in the sale of the shares by the selling stockholder, or the securities firm may purchase shares from the selling stockholder as principal and then resell the shares from time to time. The fees earned by or paid to the securities firm may be the normal stock exchange commission or negotiated commissions or underwriting discounts to the extent permissible. In addition, the securities firm may effect resales through other securities dealers, and customary commissions or concessions to these other dealers may be allowed. Sales of shares may be at negotiated prices, at fixed prices, at market prices or at prices related to market prices then prevailing. Sales of common stock may be made on the New York Stock Exchange or other exchange on which the shares are traded, in the over-the-counter market, by block trade, in special or other offerings, directly to investors or through a securities firm acting as agent or principal, or a combination of these methods. Any participating securities firm may be indemnified against certain liabilities, including liabilities under the Securities Act. Any participating securities firm may be deemed to be an underwriter within the meaning of the Securities Act, and any commission earned by the securities firm may be deemed to be underwriting discounts or commissions under the Securities Act. In connection with resales, a prospectus supplement, if required, will be filed under Rule 424(b) under the Securities Act, disclosing the name of the selling stockholder, the participating securities firm, if any, the number of shares involved and other details of the resale to the extent appropriate. 7 EXPERTS The financial statements incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended December 31, 2001, have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting.
