(1)      Shares of common stock of ENSCO International Incorporated, a Delaware
         corporation (the "Company" or the "Registrant"), par value $.10 per
         share ("Company common stock"), being registered hereby represent the
         aggregate number of shares of Company common stock issuable pursuant to
         the ENSCO International Incorporated 2000 Stock Option Plan, as amended
         (formerly known as the Chiles Offshore Inc. 2000 Stock Option Plan)
         (the "Plan"). The Company has assumed each outstanding option to
         purchase shares of common stock of Chiles, par value $.10 per share
         ("Chiles common stock"), pursuant to the Plan ("Chiles Options") as
         further explained in Note 2 below. Pursuant to Rule 416 promulgated
         under the Securities Act of 1933, as amended (the "Securities Act"),
         there are also being registered such additional shares of Company
         common stock as may become issuable under the anti-dilution provisions
         of the Plan or by reason of any dividend, stock-split, recapitalization
         or any other similar transaction without receipt of consideration that
         results in an increase in the number of shares of Company common stock
         issuable pursuant to the assumption of Chiles Options by the Company.

(2)      On May 14, 2002, the Company, Chore Acquisition, Inc., a Delaware
         corporation and wholly-owned subsidiary of the Company ("Merger Sub"),
         and Chiles Offshore Inc., a Delaware corporation ("Chiles"), entered
         into a Merger Agreement (the "Merger Agreement"). Pursuant to the
         Merger Agreement, Chiles was merged with and into Merger Sub (the
         "Merger") on August 7, 2002 (the "Effective Time"), with Merger Sub
         surviving as a wholly-owned subsidiary of the Company (the "Surviving
         Company"). As the result of the Merger, each outstanding share of
         Chiles common stock, other than dissenting shares and shares held by
         the Company, Merger Sub or Chiles, if any, was converted into the right
         to receive 0.6575 of a share of Company common stock and $5.25 in cash
         (the "Merger Consideration").

         Also as a result of the Merger, Chiles common stock is no longer
         issuable upon the exercise of Chiles Options. As of the Effective Time,
         the Company has assumed Chiles Options originally granted to Plan
         participants under the Plan. Pursuant to the Merger Agreement, Chiles
         Options have been converted into options exercisable for such amount of
         the Merger Consideration as the holders thereof would have received had
         they exercised their Chiles Options in full immediately prior to the
         Effective Time.

(3)      Estimated solely for purpose of calculating the registration fee
         pursuant to Rule 457(c) and (h) promulgated under the Securities Act,
         based on the average high and low per share prices of the common stock
         as reported by the New York Stock Exchange on August 5, 2002.

(4)      The securities being registered hereby were included in calculation of
         the registration fee paid in connection with the Company's registration
         statement no. 333-89998 on Form S-4, filed with the Securities and
         Exchange Commission (the "Commission") on June 7, 2002.

ITEM 4. DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         None.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law, or the DGCL,
provides that, subject to specific limitations in the case of derivative suits
brought by a corporation's stockholders in its name, a corporation may indemnify
any individual who is made a party or threatened to be made a party to any third
party suit or proceeding on account of being a director, officer, employee or
agent of the corporation against expenses, including attorneys' fees, judgments,
fines and amounts paid in settlement reasonably incurred by him or her in
connection with the action, if the individual:

           o      acted in good faith and in a manner he or she reasonably
                  believed to be in or not opposed to the best interests of the
                  corporation; and

           o      in the case of a criminal proceeding, had no reasonable cause
                  to believe his or her conduct was unlawful.

         Moreover, to the extent a present or former director or officer is
successful in the defense of the action, suit or proceeding, the DGCL requires a
corporation to indemnify the individual for reasonable expenses incurred
thereby.

         Article 15 of the Registrant's certificate of incorporation provides,
in general, that the Registrant must, to the full extent authorized or permitted
by law, indemnify its directors and officers under certain of the circumstances
defined in Section 145 of the DGCL, and that no director of the Registrant will
be personally liable to the Registrant or its stockholders for monetary damages
for any breach of such director's fiduciary duty, with certain exceptions.
Article 15 further allows the Registrant to purchase and maintain insurance on
behalf of the Registrant's directors, officers, employees or agents and to
provide for such indemnification by means of a trust fund, security interest,
letter of credit, surety bond, contract and/or similar arrangement. The
directors and officers of the Registrant and its subsidiaries are insured
(subject to certain exceptions and deductions) against liabilities which they
may incur in their capacity as such, including liabilities under the Securities
Act, under a liability insurance policy carried by the Registrant. The
Registrant has also entered into agreements with its officers and directors
which essentially provide that the Registrant will indemnify the officers and
directors to the extent set forth in the Registrant's certificate of
incorporation and bylaws.

         Article VII, Section 7 of the Registrant's bylaws provides that the
Registrant must indemnify its officers, directors, employees and agents to the
full extent permitted by the DGCL.

         The Merger Agreement provides that for six years from the Effective
Time, the Registrant will maintain for the benefit of the current directors and
officers of Chiles all existing rights to indemnification. These rights shall be
observed by the Registrant to the fullest extent permitted by Delaware law for a
period of six years from the Effective Time and the Registrant has agreed to
guarantee the performance of these obligations.





         From the Effective Time until September 18, 2006, the Surviving Company
shall maintain in effect, for the benefit of the current directors and officers
of Chiles with respect to acts or omissions occurring prior to the Effective
Time, the existing policy of directors' and officers' liability insurance
maintained by Chiles as of the date of the Merger Agreement in the form
disclosed by Chiles to the Registrant prior to the date of the Merger Agreement;
provided that (a) the Surviving Company may substitute for such existing policy
a policy or policies of comparable coverage and (b) the Surviving Company shall
not be required to pay annual premiums for such existing policy (or for any
substitute policies) in excess of $200,000 in the aggregate. In the event any
future annual premiums for such existing policy (or any substitute policies)
exceed $200,000 in the aggregate, the Surviving Company shall be entitled to
reduce the amount of coverage of the existing policy (or any substitute
policies) to the amount of coverage that can be obtained for an aggregate annual
premium of $200,000.

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in this Registration Statement or

this Registration Statement;

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof; and

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

(b) The undersigned Registrant hereby further undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant





has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Dallas, State of Texas, on August 7, 2002.
