Item 4.  Description of Securities.

         Not applicable.

                                       2



Item 5.  Interests of Named Experts and Counsel.

         Not applicable.

Item 6.  Indemnification of Directors and Officers.

         Article IV, Section 3 of our Second Amended and Restated By-Laws states
that we shall indemnify and advance expenses to directors, officers, employees
and agents to the maximum extent permissible under the Texas Business
Organization Code, or TBOC.

         Article VII of our Amended and Restated Certificate of Formation
precludes any personal liability by a director to us or our shareholders for
monetary damages for an act or omission in the director's capacity as a
director, except for liability for (1) any breach of the director's duty of
loyalty to us or our shareholders, (2) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (3) a
transaction from which the director received an improper personal benefit, or
(4) an act or omission for which the liability of a director is expressly
provided for by statute. Article VII also provides that the liability of
directors shall be eliminated or limited to the fullest extent permitted by
TBOC.

         While Article VII provides directors with protection from awards of
monetary damages for breaches of the duty of care, it does not eliminate each
director's duty of care. Accordingly, Article VII has no effect on the
availability of an equitable remedy such as an injunction or rescission based
upon a director's breach of the duty of care. In addition, Article VII applies
only to claims against the director arising out of his or her role as a
director, and does not apply to the director's role as an officer or in any
capacity other than that of a director or to the director's responsibilities
under other law, such as the federal securities laws. Article VII relates only
to liabilities of directors to us and our shareholders, and does not affect
liability to third parties.

         We maintain an officers' and directors' liability insurance policy
covering all of our officers and directors. The effect of such policy is to
indemnify our officers and directors against losses incurred by them while
acting in such capacities.

         Insofar as indemnification by us for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act"), may be permitted to
our directors, officers or persons controlling us pursuant to the foregoing
provisions, we have been informed that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is therefore unenforceable.

Item 7.  Exemption from Registration Claimed.

         Not applicable.

Item 9.  Undertakings.

     (a) Atwood Oceanics, Inc. hereby undertakes:

              (1)    To file, during any period in which offers or sales
                     are being made, a post-effective amendment to this
                     registration statement:

                   (i)     To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                   (ii)    To reflect in the prospectus any facts or events
                           arising after the effective date of the
                           registration statement (or the most recent
                           post-effective amendment thereof) which, individually
                           or in the aggregate, represent a fundamental change
                           in the information set forth in the registration
                           statement. Notwithstanding the foregoing, any
                           increase or decrease in volume of securities offered
                           (if the total dollar value of securities offered
                           would not exceed that which was registered) and any
                           deviation from the low or high end of the estimated
                           maximum offering range may be reflected in the
                           form of prospectus filed with the Securities and
                           Exchange Commission pursuant to Rule 424(b) if, in
                           the aggregate, the changes in volume and price
                           represent no more than a 20 percent change in the
                           maximum aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement; and

                   (iii)   To include any material information with
                           respect to the plan of distribution not
                           previously disclosed in the registration
                           statement or any material change to such
                           information in the registration statement;

                     Provided, however, that paragraphs (a)(1)(i) and
                     (a)(1)(ii) above do not apply if the information
                     required to be included in a post-effective amendment
                     by those paragraphs is contained in reports filed
                     with or furnished to the Securities and Exchange
                     Commission by Atwood Oceanics, Inc. pursuant to
                     section 13 or section 15(d) of the Securities
                     Exchange Act of 1934 that are incorporated by
                     reference in the registration statement.

              (2)    That, for the purpose of determining any liability
                     under the Securities Act of 1933, 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.

              (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) Atwood Oceanics, Inc. hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of its
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the 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 of 1933 may be permitted to our directors, officers and

                                       5


controlling persons pursuant to the foregoing provisions, or otherwise, Atwood
Oceanics, Inc. has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by Atwood
Oceanics, Inc. of expenses incurred or paid by a director, officer or
controlling person of Atwood Oceanics, Inc. 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, Atwood Oceanics, Inc.
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 Act and will be governed by the final adjudication of such
issue.

         Pursuant to the requirements of the Securities Act of 1933, Atwood
