     This Amendment No. 2 to Schedule 13G (this "Amendment No. 2") is being 
filed to amend and restate in its entirety the Schedule 13G (the "Initial 
Schedule 13G") filed by the Filing Persons (as defined below, but excluding 
International Insurance Investors, L.P. ("III")), J.P. Morgan Capital Corp. 
("J.P. Morgan"), Bacardi Capital Ltd. ("Bacardi") and Centre Reinsurance 
Limited ("Centre Re") on February 14, 1996, as amended and restated by 
Amendment No. 1 to Schedule 13G, filed on February 14, 1997 by such parties 
(with the exception of Centre Re) and Centre Reinsurance (Bermuda) Limited 
(which subsequently changed its name to Centre Solutions (Bermuda) Limited 
("Centre Solutions")), relating to the common stock, par value $.01 per share 
(the "Common Stock"), issued by Superior National Insurance Group, Inc., a 
Delaware corporation (the "Issuer").

     This Amendment No. 2 is being filed to report the distribution on 
November 21, 1996 to the limited partners and general partner of III of the 
warrants to purchase 1,474,306 shares of Common Stock that were held of 
record by International Insurance Advisors, Inc. ("IIA"), as agent for the 
partners of III.  This Amendment No. 2 is also being filed to report the sale 
on May 14, 1997 and May 30, 1997, by J.P. Morgan and Bacardi, respectively, 
each of which is a limited partner of III, of warrants to purchase 138,785 
and 92,188 shares of Common Stock, respectively, to entities that are not 
party to the Agency Agreement (as defined in Item 4 below).  In connection 
with these sales, J.P. Morgan and Bacardi also transferred to the general 
partner of III an aggregate of 31,435 warrants, which are subject to the 
Agency Agreement.  As a result of these sales, the number of warrants and 
underlying shares of Common Stock with respect to which IIA acts as agent 
under the Agency Agreement (and as a result, is deemed to own beneficially 
for purposes of Rule 13d-3 under the Securities Exchange Act of 1934, as 
amended (the "Act")) decreased from 1,474,306 to 1,243,332 shares.

     This Amendment No. 2 is also being filed to report the transfer to III 
on December 11, 1997 by the holders of the warrants that are subject to the 
Agency Agreement of a portion of each such holders' warrants, for an 
aggregate of 204,759 warrants.  These warrants were transferred to III so 
that they could be held (subject to IIA's revocable agency relationship under 
the Agency Agreement) in reserve for the payment to Centre Re, a limited 
partner of III, and IIA (collectively, the "Advisers"), of their incentive 
fee under III's investment advisory agreements.  This Amendment No. 2 is also 
being filed to report the acquisition on December 10, 1998 by Robert A. 
Spass, Paul H. Warren and Bradley E. Cooper of warrants to purchase an 
aggregate of 65,651 shares of Common Stock.

ITEM 4.  OWNERSHIP.

INTERNATIONAL INSURANCE ADVISORS, INC.

The responses of IIA to Items 5-9 and Item 11 of the cover page to this
Amendment No. 2 are incorporated herein by reference.

The 1,243,332 shares of Common Stock that IIA beneficially owns consist of
warrants (the "Warrants") that, for purposes of Rule 13d-3 under the Act, are
exercisable within 60 days of the date hereof, and would represent approximately
6.5% of the outstanding shares of Common Stock if exercised.  The Warrants are
not held by IIA, but rather, are subject to a revocable agency relationship
whereby IIA acts as an agent, on behalf of the holders of the Warrants, with
respect to the exercise of the voting and consent rights set forth in the
Warrants and that attach to the underlying Common Stock.  This agency
relationship was established pursuant to the Agency and Proxy Agreement dated
March 16, 1992, a copy of which is attached as Exhibit A to the Initial
Schedule 13G (the "Agency Agreement").  The following persons are subject to
this agency relationship: III, International Insurance Investors (Bermuda)
Limited ("III (Bermuda)"), Bacardi, Centre Re, the Trustees of the Estate of
Bernice P. Bishop ("Bishop Estate"), J.P. Morgan, Carlisle Ventures, Inc., Beach
Haven Investors, Inc., Fluor Reinsurance Investments, Inc., Robert A. Spass,
Paul H. Warren, Bradley E. Cooper, Craig F. Schwarberg and the International
Insurance Advisors, Inc. 401(k) and Pension Plans (the "IIA Pension Plans"), all
of which, with the exception of III, III (Bermuda), Bradley E. Cooper and Craig
F. Schwarberg, are limited partners of III.  III (Bermuda) is the sole general
partner of III.  IIA is the financial adviser to III.  Centre Solutions, which
is not a partner of III, acquired its Warrants from Centre Re, a limited partner
of III and wholly owned subsidiary of Centre Solutions.  The Warrants acquired
by Centre Solutions are subject to IIA's agency relationship.

The Warrants, which were purchased from the Issuer by III in March 31, 1992 in a
transaction which also included the issuance to III of the Issuer's 14.5% Senior

- --------------------
(2)  The outstanding principal amount of the Voting Notes is $30,000.  The
     number of votes attaching to the Voting Notes is equal to the number of
     shares of Common Stock that may be purchased upon exercise of the Warrants
     that were issued in that March 31, 1992 transaction and that remain
     outstanding and are unexercised as of the applicable record date for a
     stockholder vote.  As of the date hereof, the number of votes held by III,
     the holder of the Voting Notes, was equivalent to 1,566,465 shares of
     Common Stock.  The holder of the Voting Notes is permitted to vote only in
     director elections, director removals, votes on amending that right to
     vote, and changes to the number of authorized directors.  The specific
     voting rights of the Voting Notes are set forth in the Issuer's Certificate
     of Incorporation and Bylaws.

Subordinated Voting Notes due April 1, 2002 (the "Voting Notes")(2), were
originally issued directly to IIA, as agent for each of the limited partners and
general partner of III, pursuant to the Agency Agreement.  On November 21, 1996
the Warrants, which were held of record by IIA, as agent, were distributed to
the partners of III; however, IIA's revocable agency relationship with such
partners under the Agency Agreement was reestablished after the distribution. 
Under this agency relationship, in the event that the holders of the Warrants,
the underlying Common Stock and/or any other security issued as a dividend or
distribution thereon (together with such Common Stock, the "Underlying
Securities") are entitled to vote or consent with respect to any matter (with
certain limited exceptions), then IIA, as agent and proxy, shall exercise such
voting or consent right with respect to all Warrants and/or Underlying
Securities then subject to such relationship.  This agency relationship may be
revoked by the holder of the Warrants upon 10 days' notice to IIA.  The Agency
Agreement may be terminated by IIA upon 30 days' notice to the other parties to
the Agency Agreement and will be terminated upon the termination of III pursuant
to its partnership agreement.

were transferred to III on December 11, 1997 by each holder of the Warrants
(representing a portion of the Warrants held by each such holder) so that they
could be held by III (subject to IIA's revocable agency relationship) in reserve
for the payment to the Advisers of their incentive fee under III's investment
advisory agreements.
