ITEM 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED. Reference is hereby made to the Registration Statement on Form 8-A filed by Smith International, Inc. (the "Company") with the Securities and Exchange Commission on June 15, 2000, relating to the Rights Agreement by and between the Company and Equiserve Trust Company, N.A., successor to First Chicago Trust Company of New York dated June 2, 2000, as amended (the "Rights Plan"). Such Form 8-A is hereby incorporated by reference. Pursuant to the Rights Plan, our Board of Directors declared a dividend of one junior participating preferred stock purchase right ("Right") for each share of our common stock outstanding on June 20, 2000. The Board also authorized the issuance of one such Right for each share of our common stock issued after June 20, 2000 until the occurrence of certain events. On June 6, 2002, we announced that our Board of Directors declared a two-for-one stock split, which was effected in the form of a stock dividend and paid on July 8, 2002 to stockholders of record as of June 20, 2002. On July 21, 2005, we announced that our Board of Directors declared a two-for-one stock split, to be effected in the form of a stock dividend (the "Stock Dividend"). The dividend was paid on August 24, 2005 to stockholders of record as of August 5, 2005. Pursuant to the provisions of the Rights Plan, the effect of the stock split is that effective August 5, 2005, each outstanding share of common stock and each share of common stock issued in the future until the Distribution Date (as defined in the Rights Plan) shall have attached a right to purchase one four-hundredth (1/400) of a Preferred Share (as defined in the Rights Plan) upon the terms and conditions set out in the Rights Plan. A copy of a Certificate of Adjusted Purchase Price or Number of Shares, dated as of August 4, 2005, delivered by the Company to the Rights Agent and the Company's transfer agent and setting forth the required adjustment is attached hereto as Exhibit 99.2 and is incorporated herein by reference. The description of the Rights set forth below reflects certain additional adjustments arising from the Stock Dividend and is qualified in its entirety by reference to the Rights Plan. The Rights are exercisable upon the occurrence of certain events related to a person (an "Acquiring Person") acquiring or announcing the intention to acquire beneficial ownership of 20 percent or more of our common stock. In the event any person becomes an Acquiring Person, each holder (except an Acquiring Person) will be entitled to purchase, at an effective exercise price of $87.50, subject to adjustment, shares of our common stock having a market value of twice the Right's exercise price. The Acquiring Person will not be entitled to exercise these Rights. In addition, if, at any time after a person has become an Acquiring Person, we are involved in a merger or other business combination transaction, or sell 50 percent or more of its assets or earning power to another entity, each Right will entitle its holder to purchase, at an effective exercise price of $87.50, subject to adjustment, shares of common stock of such other entity having a value of twice the Right's exercise price. After a person or group becomes an Acquiring Person, but before an Acquiring Person owns 50% or more of our common stock, the Board may extinguish the Rights by exchanging one share of common stock, or an equivalent security, for each Right, other than Rights held by the Acquiring Person. In the event the Rights become exercisable and sufficient shares of our common stock are not authorized to permit the exercise of all outstanding Rights, we are required under the Rights Plan to take all necessary action including, if necessary, seeking stockholder approval to obtain additional authorized shares. The Rights are subject to redemption at the option of the Board of Directors at a price of one-quarter of a cent per Right until the occurrence of certain events. The Rights currently trade with our common stock, have no voting or dividend rights and expire on June 8, 2010. ITEM 2.
