                                     PART II
                             RULE 12B-25(B) AND (C)

      If the subject report could not be filed without unreasonable effort or
expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
following should be completed. (Check box if appropriate)

      (a)   The reasons described in reasonable detail in Part III of this form
            could not be eliminated without unreasonable effort or expense;

      (b)   The subject annual report, semi-annual report, transition report on
            Form 10-K, 10-KSB, 20-F, 11-K or Form N-SAR, or portion thereof,
            will be filed on or before the fifteenth calendar day following the
/X/         prescribed due date; or the subject quarterly report or transition
            report on Form 10-Q, 10-QSB or portion thereof will be filed on or
            before the fifth calendar day following the prescribed due date; and

      (c)   The accountant's statement or other exhibit required by Rule
            12b-25(c) has been attached if applicable.


                                    PART III
                                    NARRATIVE

      State below in reasonable detail the reasons why Form 10-K, 10-KSB, 11-K,
20-F, 10-Q, 10-QSB, N-SAR or the transition report or portion thereof could not
be filed within the prescribed time period.

           The Company respectfully requests an extension of time for the filing
           of its Form 10-Q for the quarterly period ended March 31, 2002, from
           May 15, 2002 to May 20, 2002. This request is primarily made as a
           result of the Company's recent change of its principal independent
           accountant, as reported on a Current Report on Form 8-K, dated April
           30, 2002. This extension is requested in order to allow additional
           time for the Company's new principal independent accountant to
           complete its review of the Company's interim financial statements
           prior to the Company's filing of its Form 10-Q as required by Rule
           10-01(d) of Regulation S-X.

           The Company is also evaluating the potential financial statement
           impacts of an unfavorable ruling it received on May 14, 2002 in
           respect of certain unfair labor practice claims.  This item is more
           fully discussed in a Current Report on Form 8-K also filed on May
           15, 2002.

                                     PART IV
                                OTHER INFORMATION

(1)   Name and telephone number of person to contact in regard to this
      notification.

      Daniel D. Maddox                (713)                 267-3891
      (Name)                       (Area Code)         (Telephone Number)

(2)   Have all other periodic reports required under Section 13 or 15(d) of the
      Securities Exchange Act of 1934 or Section 30 of the Investment Company
      Act of 1940 during the preceding 12 months or for such shorter period that
      the registrant was required to file such report(s) been filed? If the
      answer is no, identify report(s). [X] Yes [ ] No

(3)   Is it anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion
      thereof?
      [X] Yes    [  ] No

      If so, attach an explanation of the anticipated change, both narratively
      and quantitatively, and, if appropriate, state the reasons why a
      reasonable estimate of the results cannot be made.

           Excluding non-recurring items from both comparable periods, the
           Company's operating loss in the first quarter of 2002 will be smaller
           than that of the fourth quarter of 2001. Much of this improvement
           will be attributable to better results in the Bauxite and Alumina
           segment, where the Gramercy facility has effected a substantial
           reduction in its start-up costs and the Company's 49% owned
           affiliate, Kaiser Jamaica Bauxite Company, has improved its operating
           performance. The favorable impacts of these improvements in operating
           performance are expected to be partially offset by a significant
           increase in Corporate segment expenses as a result of higher pension,
           postretirement medical and other benefit expenses.

                  (Name of Registrant as Specified in Charter)
