ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

ITEM 2.03.  CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN
            OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT

ITEM 8.01.  OTHER EVENTS

         On August 27, 2004, Diamond Offshore Drilling, Inc. (the "Company")
issued and sold, in a private placement (the "Private Placement") exempt from
the registration requirements under the Securities Act of 1933, as amended (the
"Securities Act"), $250 million aggregate principal amount of its 5.15% Senior
Notes Due September 1, 2014 (the "Notes"). The Notes were sold in the United
States only to accredited investors pursuant to an exemption from the Securities
Act, and subsequently resold to qualified institutional buyers pursuant to Rule
144A under the Securities Act and to non-U.S. persons in accordance with
Regulation S under the Securities Act. The Notes have not been registered under
the Securities Act and may not be offered or sold in the United States absent
registration or an applicable exemption from registration requirements. The
Private Placement resulted in net proceeds to the Company of approximately $248
million, which the Company intends to use to partially fund a refinancing of the
Company's zero coupon convertible debentures due 2020 ("Debentures"). The
holders of those Debentures can require the Company to repurchase their
Debentures on June 6, 2005 at the issue price plus accrued original issue
discount of 3.5% per year (the "Accreted Value"). The Company has the option to
repurchase all or part of the Debentures on or after June 6, 2005 at the
Accreted Value. As of June 30, 2004, the aggregate Accreted Value of the
Debentures was approximately $463 million. On June 6, 2005, the Accreted Value
of the Debentures currently outstanding will be approximately $478 million.

         The Notes are governed by an Indenture, dated as of February 4, 1997,
between the Company and JPMorgan Chase Bank (formerly known as The Chase
Manhattan Bank), as Trustee, as supplemented by the Fourth Supplemental
Indenture, dated as of August 27, 2004 (the "Fourth Supplemental Indenture"),
between the Company and JPMorgan Chase Bank, as Trustee (as so supplemented by
the Fourth Supplemental Indenture, the "Indenture"). In connection with the
Private Placement, the Company entered into the Fourth Supplemental Indenture
and an Exchange and Registration Rights Agreement, dated August 27, 2004 (the
"Registration Rights Agreement"), with Goldman, Sachs & Co., the initial
purchaser of the Notes.

         The Notes bear interest at 5.15% per year, payable semiannually in
arrears on March 1 and September 1 of each year, beginning March 1, 2005, and
mature on September 1, 2014. The Notes are unsecured and unsubordinated
obligations of the Company and they rank equal in right of payment to the
Company's existing and future unsecured and unsubordinated indebtedness,
although the Notes will be effectively


                                       2


subordinated to all existing and future obligations of the Company's
subsidiaries. The Company has the right to redeem all or a portion of the Notes
for cash at any time or from time to time on at least 15 days but not more than
60 days prior written notice, at the redemption price specified in the Indenture
plus accrued and unpaid interest on the principal amount of the Notes redeemed
to the date of redemption. The Indenture contains covenants that limit, among
other things, subject to certain exceptions, the Company's ability to (a)
consolidate with or merge into another entity or convey or transfer its
properties and assets substantially as a whole, (b) create liens and (c) enter
into a sale and lease-back transaction covering a drilling rig or drillship.

         The Company has agreed, pursuant to the Registration Rights Agreement,
to file a registration statement relating to an offer to exchange the Notes for
debt securities issued by the Company which are substantially identical in all
material respects to the Notes. The Company agreed to file such registration
statement within 120 days from August 27, 2004 and to use its reasonable best
efforts to cause such registration statement to be declared effective by the
Securities and Exchange Commission within 180 days from August 27, 2004. If the
Company fails to file a registration statement, or a registration statement
fails to become effective, by the respective deadline set forth in the
Registration Rights Agreement, or if the required exchange offer is not
completed within 45 days after the initial effectiveness of the registration
statement for the exchange offer or if, after a registration statement has
become effective, it ceases under certain circumstances to be effective or
available, then the Registration Rights Agreement provides that the Company will
be obligated to pay additional interest in the amount of 0.25% per year for the
first 90 days and 0.50% per year thereafter until no such failure remains in
effect.

        The description set forth above is qualified in its entirety by
reference to the Indenture and the Registration Rights Agreement, which are
filed as exhibits to this report. This report does not constitute an offer to
sell or the solicitation of an offer to buy any securities.
