PART II -- RULES 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, Form 20-F, 11-K or Form N-SAR, or portion thereof,
/X/         will be filed on or before the fifteenth calendar day following
            the prescribed due date; or the subject quarterly report of
            transition report on Form 10-Q, 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 Forms 10-K, 20-F, 11-K, 10-Q,
N-SAR, or the transition report or portion thereof, could not be filed
within prescribed time period.

     Superior National could not eliminate the reasons for its inability to
file the Quarterly Report on Form 10-Q for the Quarterly Period ended
September 30, 1999 that is the subject of this Notification of Late Filing on
Form 12b-25 without unreasonable effort or expense because of the substantial
amounts of time, energy and resources that Superior National's management has
had to devote in defending and pursuing its significant legal dispute with
Inter-Ocean Reinsurance Company Ltd. and American Re-Insurance Company over
Inter-Ocean's purported rescission of its aggregate excess of loss
reinsurance agreement that gives effect to its $175 million loss reserves
guarantee and the liquidity, regulatory and other issues that this dispute
has created. In addition, since July 1999 when J. Chris Seaman, Superior
National's President and Chief Executive Officer, was promoted from Chief
Financial Officer, pending the hiring of a permanent replacement, Superior
National has not had the services of a full-time Chief Financial Officer and
has had to rely instead on the services of consultants and Mr. Seaman to act
in such a capacity.

                                            (ATTACH EXTRA SHEETS IF NEEDED)
                                                            SEC 1344 (6/94)




PART IV -- OTHER INFORMATION

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

J. Chris Seaman            (818)                 880-1600
- ------------------------------------------------------------------------------
    (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
     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.

    We recorded an underwriting loss from continuing operation of $60.0
    million in the nine month period ended September 30, 1999, versus an
    underwriting profit of $8.9 million in the corresponding period in 1998.
    The decrease in underwriting profit from continuing operations was
    primarily the result of a $60.0 million increase in our claim and claim
    adjustment expense reserves due to adverse loss development and
    cancellation of a contract with affiliates of Zurich Reinsurance (North
    America), Inc.  In addition to the $60.0 million claim and claim
    adjustment expense reserve increase, our underwriting profit from
    continuing operations decreased partially due to costs associated with
    combining the operations of the newly acquired insurance subsidiaries of
    Business Insurance Group, Inc. ("BIG"), California Compensation Insurance
    Company, Commercial Compensation Insurance Company, and Combined Benefits
    Insurance Company (the "BIG insurance subsidiaries"), with Superior
    National. During the nine months ended September 30, 1999, we realized a
    net loss of $30.1 million or $1.70 diluted earnings per share and $1.70
    basic earnings per share as compared to net income of $6.2 million or
    $0.79 diluted earnings per share and $1.07 basic earnings per share for
    the nine months ended September 30, 1998.  The decrease in net income of
    $36.2 million was primarily the result of the decrease reflected in the
    underwriting profit from continuing operations which was partially offset
    by an increase of $18.0 million in net investment income.  The increase
    in net investment income was due to an increase in invested assets which
    was the result of our December 10, 1998 acquisition of BIG. Partially
    offsetting the increase in net investment income was an increase in
    interest expense.  Our cash flow and general financial condition has been
    and, until it is resolved, will be materially and adversely affected by
    our dispute with Inter-Ocean Reinsurance Ltd. and American Re-Insurance
    Company over Inter-Ocean's purported recision of its aggregate excess of
    loss reinsurance agreement, which gives effect to its $175.0 million loss
    reserves guarantee, which went into effect immediately before we acquired
    BIG.
