ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

      In connection with the recently enacted Section 409A of the Internal
Revenue Code of 1986, (the "Code") which regulates deferred compensation plans,
the Board of Directors of Smith International, Inc. (the "Company") approved and
adopted on December 8, 2004 the Smith International, Inc. Post-2004 Supplemental
Executive Retirement Plan (the "Post-2004 SERP"), to be effective December 31,
2004. In connection with the adoption of the Post-2004 SERP and recently enacted
Code Section 409A, the Company has also suspended contributions, other than such
contributions that were earned and vested as of December 31, 2004, to the
Company's existing Smith International, Inc. Supplemental Executive Retirement
Plan effective as of December 31, 2004. The following is a summary of the
material provisions of the Post-2004 SERP.

      The Post-2004 SERP is a non-qualified, deferred compensation plan, for the
benefit of officers and certain other eligible employees of the Company as
selected by the Compensation and Benefits Committee of the Board of Directors of
the Company (the "Compensation Committee"). Participants may contribute, on a
pre-tax basis, up to 100 percent of their cash compensation. Distributions may
generally be made either as a lump sum or installment payments following the
participant's termination of employment due to death, disability or other
separation from service. Distributions may also be made on a limited basis and
to the extent necessary as a lump sum upon the occurrence of the participant's
unforeseeable financial emergency as approved by the Compensation Committee. The
Post-2004 SERP also provides for Company contributions, as follows:

      Age-Weighted Contributions. Effective as of the last day of each quarter
during the year, a contribution by the Company will be allocated under the
Post-2004 SERP based on the participant's age-weighted contribution percentage
("AWCP") ranging from 2% to 6%. The Post-2004 SERP provides that the AWCP for
executive officers is 6% regardless of age. The difference between a
participant's (i) "Total 401(k) Compensation" and (ii) "Net 401(k) Compensation"
is multiplied by the AWCP to compute the age-weighted contribution. "Total
401(k) Compensation" generally means the total of all cash amounts paid by the
Company to a participant, including deferred amounts. "Net 401(k) Compensation"
generally means Total 401(k) Compensation less participant contributions to the
Post-2004 SERP, but not to exceed the limit set under Code Section 401(a)(17)
($210,000 in 2005 and $205,000 in 2004).

      Matching Contributions. The Post-2004 SERP contains matching provisions
that mirror the matching formulas in effect for the Company's 401(k) Plan, but
without regard to certain Code limits applicable to the 401(k) Plan. Matching
contributions for a plan year in both the Post-2004 SERP and the 401(k) Plan
combined cannot exceed 6% of a participant's Total 401(k) Compensation net of
any incentive bonus. Executive officers will receive matching contributions up
to 6% of their Total 401(k) Compensation.

      Additional Company Contributions. In addition to the contributions
described above, the Company may be required to make contributions to
participants' accounts to the extent they are deemed to be invested in the money
market fund that is available as a deemed investment option under the Post-2004
SERP. These additional contributions are made to guarantee an investment return
equal to 120% of the long-term applicable federal rate ("AFR"). Therefore, for
the portion of each participant's account deemed to be invested in the money
market fund that is earning less than 120% of AFR, the Company makes a
contribution equal to the difference in interest accruals between the money
market fund rate



actually earned by the money market fund and the AFR, which contribution is
credited to the participant's account under the Post-2004 SERP.

      Discretionary Profit Sharing Contributions. The Compensation Committee
may, in its discretion, determine the amount of any profit sharing contribution
for a plan year and how that amount is to be allocated among the accounts of the
Post-2004 SERP participants.

      In the event of insolvency or bankruptcy, all assets allocable to the
Post-2004 SERP are available to satisfy the claims of all general unsecured
creditors of the Company. The Company will establish a trust to serve as a
source of funds from which it can satisfy its obligations under the Post-2004
SERP. Participants in the Post-2004 SERP will have no rights to any assets held
in the trust, except as general creditors of the Company. A participant's rights
to any amounts credited to an account under the Post-2004 SERP cannot be
anticipated, alienated, sold, assigned, pledged, encumbered or charged by the
participant and may only pass upon the participant's death pursuant to a
beneficiary designation made by the participant under the Post-2004 SERP. The
Company may, by action of the Compensation Committee, terminate the Post-2004
SERP with respect to future contributions; provided, however, such termination
shall not affect any participant's right to receive any distribution due under
the Post-2004 SERP.

      The Post-2004 SERP will be interpreted by the Compensation Committee in
such manner as necessary to comply with the requirements of Code Section 409A
and the authority issued thereunder.
