         Pursuant to the terms and provisions of Article 4.04 of the Texas

Articles of Amendment to its Restated Articles of Incorporation:


                                       I.

         The name of the corporation is Atwood Oceanics, Inc.

                                       II.

         The Restated Articles of Incorporation are hereby amended by adding a
new Article X, the full text of which provision is as follows:


                                    ARTICLE X

                  A director of the Corporation shall not be liable to the
         Corporation or its shareholders for monetary damages for an act or
         omission in the director's capacity as a director, except for liability
         for (i) a breach of the director's duty of loyalty to the Corporation
         or its shareholders, (ii) an act or omission not in good faith or that
         involves intentional misconduct or a knowing violation of the law,
         (iii) a transaction from which the director received an improper
         benefit, whether or not the benefit resulted from an action taken
         within the scope of the director's office, or (iv) an act or omission
         for which the liability of a director is expressly provided for by
         statute.

                  If the Texas Miscellaneous Corporation Laws Act is amended
         after approval by the shareholders of this Article to authorize
         corporate action further eliminating or limiting the personal liability
         of directors, then the liability of a director of the Corporation shall
         be eliminated or limited to the fullest extent permitted by the Texas
         Miscellaneous Corporation Laws Act, as so amended.

                  Any repeal or modification of the foregoing paragraph by the
         shareholders of the Corporation shall not



         adversely affect any right or protection of a director of the
         Corporation existing at the time of such repeal or modification.


                                      III.

         The foregoing amendment to the Restated Articles of Incorporation was
adopted by the shareholders on February 13, 1992.


                                       IV.

         The number of shares of the corporation outstanding and entitled
to vote on the foregoing amendment at the time of such adoption was 6,582,613.


         The holders of 5,549,632 outstanding shares entitled to vote on the
