ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On April 26, 2005, the stockholders of Smith International, Inc. (the "Company")
approved the amended and restated 1989 Long-Term Incentive Compensation Plan,
effective January 1, 2005 (the "Plan"). The Plan had previously been approved by
the Company's Board of Directors on December 8, 2004, subject to stockholder
approval. The Plan allows for the award to employees, including officers, of
stock options, stock appreciation rights, restricted stock awards,
performance-based restricted stock awards and other stock awards, including
restricted stock units and performance-based restricted stock units. The Plan
was amended to conform to changes in the Internal Revenue Code and to provide
for the grant of performance-based awards. In addition, certain technical and
administrative amendments were made to the Plan. A copy of the Plan is attached
hereto as Exhibit 10.1.

A form of award agreement for grants of performance-based restricted stock units
under the Plan is attached hereto as Exhibit 10.2. The awards are subject to
both performance measures and continued employment. The performance measure is
based on return on equity, as established annually by the Compensation and
Benefits Committee of the Company's Board of Directors.
