Pursuant to the terms of the acquisition agreement, we will pay all expenses of registering the shares under the Securities Act of 1933, including all registration and filing fees, printing expenses and the fees and disbursements of our counsel and accountants. The agreement also provides that we will indemnify the selling stockholder against certain civil liabilities, including liabilities under the Securities Act of 1933, or will contribute to payments the selling stockholder may be required to make in respect thereof. The selling stockholder will pay all fees and disbursements of its counsel and all brokerage fees, commissions and expenses for any shares that are registered and that it sells. We expect to withdraw registration of any unsold shares on or shortly after November 16, 2003, when we expect the shares will be eligible for public sale pursuant to the exemption from registration provided by Rule 144(k) under the Securities Act of 1933. The selling stockholder may assign its registration rights in connection with any distribution in accordance with applicable law of its shares to its shareholders. Any distributees will be included in a prospectus supplement if they wish to use this prospectus to re-offer the shares. The following table sets forth the beneficial ownership of common stock by the selling stockholder as of December 4, 2001, all of which may be sold pursuant to this prospectus: <Table> <Caption> PERCENTAGE OF NAME OF NUMBER OF SHARES OUTSTANDING SELLING STOCKHOLDER OWNED (1) SHARES - -------------------------------------------- ---------------- ------------- CiDRA Corporation ........................ 1,896,149 1.7 </Table> - ---------- (1) Because the selling stockholder may offer all or a portion of the shares pursuant to this prospectus, we cannot estimate as to the number of shares of our common stock that the selling stockholder will hold upon termination of any sales. 4 PLAN OF DISTRIBUTION The selling stockholders have advised us that they may sell the shares on the New York Stock Exchange or otherwise, at market prices or at negotiated prices. They may sell shares by one or a combination of the following: o a block trade in which a broker or dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction; o purchases by a broker or dealer as principal and resale by the broker or dealer for its account pursuant to this prospectus; o ordinary brokerage transactions and transactions in which a broker solicits purchasers; o privately negotiated transactions; and o put or call option transactions relating to the shares (whether such options are listed on an options exchange or otherwise), through short sales of shares, or a combination of such methods, at varying prices determined at the time of sale or at negotiated prices. In connection with the sale of shares, the selling stockholders may enter into hedging transactions with brokers, dealers or others, who, in turn, may engage in short sales of the shares in the course of hedging the positions they assume; sell short or deliver shares to close out their positions; or loan shares to brokers, dealers or others who may then sell such shares. Brokers or dealers engaged by the selling stockholders may arrange for other brokers or dealers to participate in sales of shares. Brokers or dealers will receive commissions or discounts from selling stockholders in amounts to be negotiated prior to the sale. The selling stockholders and any broker-dealers that participate in the distribution may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, and any proceeds or commissions received by them or any profits on the resale of shares sold by broker-dealers, may be deemed to be underwriting discounts and commissions. When any of the selling stockholders notifies us of a particular offering of common stock under this prospectus, we will file a prospectus supplement, if required by the Securities Act of 1933, setting forth: o the number of shares being offered and the terms of the offering, including the purchase price; o the name of each of the participating broker-dealers or agents; o the purchase price paid for the shares purchased from the selling stockholders; and o any items constituting compensation from the selling stockholders. We will not receive any of the proceeds from the sale of the shares offered by this prospectus. LEGAL MATTERS Burt M. Martin, our Vice President - Law, has advised us with respect to the validity of the shares of common stock offered by this prospectus. Mr. Martin holds options to purchase 239,013 shares of common stock. 5 EXPERTS The consolidated financial statements of Weatherford International, Inc. and the related consolidated financial statement schedule incorporated by reference in this prospectus and elsewhere in the registration statement, to the extent and for the periods indicated in their report, have been audited by Arthur Andersen LLP, independent public accountants, and are incorporated by reference in reliance upon the authority of said firm as experts in giving said report. 6
