the  Schedule 13D filed by the  undersigned.  This  Amendment  No. 11 amends the
Schedule 13D as specifically set forth.

     Item 4 is hereby amended to add the following:

            On April 18, 2003, Steel Partners II delivered a letter to the Board
of Directors of the Issuer (the "Board") responding to the Board's withdrawal of
a settlement  offer with Steel Partners II which would have, among other things,
reconstituted the Board at the 2003 Annual Meeting of Stockholders of the Issuer
and the  attempt  of one or more of the  controlling  members  of the  Board  to
facilitate a transaction between Steel Partners II and a third party purportedly
willing to purchase  Steel  Partners  II's entire  investment in the Issuer at a
significant  premium to the current market price of the Issuer's common stock. A
copy of the letter is attached as an exhibit hereto and  incorporated  herein by
reference.

     Item 7 is hereby amended to add the following exhibit:

            13. Letter from Steel Partners II, L.P. to the Board of Directors of
                United Industrial Corporation, dated April 18, 2003.

New York, New York 10022

Gentlemen:

            Once  again the  controlling  members of the Board of  Directors  of
United Industrial  Corporation (the "Company") have withdrawn a settlement offer
with Steel  Partners II, L.P.  ("Steel")  which would have,  among other things,
reconstituted the Board at the 2003 Annual Meeting.  As the largest  stockholder
of the Company, we made every effort to negotiate a fair and amicable resolution
to our longstanding  differences with the controlling  members of the Board that
we believe would be in the best interests of all stockholders.

            We were therefore quite shocked by the attempt of one or more of the
controlling members of the Board to bribe Steel Partners by trying to identify a
third party  apparently  willing to purchase  Steel's  entire  investment in the
Company at a  significant  premium to the current  market price of the Company's
common  stock.  We want to make this point  absolutely  clear to you. We are not
interested  in bribes,  greenmail or any  transaction  that will not benefit all
stockholders of the Company.  Our only interest is maximizing  stockholder value
for all stockholders  which we believe,  in the case of the Company,  must begin
with a  united  Board of  Directors  whose  accountability  to  stockholders  is
unquestioned and fiduciary responsibility is the gospel.

            For the record,  we continue to believe that the  composition of the
Board  must  change  and  that  the  Company  must  timely   announce   material
developments.  We believe  all  stockholders  should  know that (1) Hal Gelb has
agreed at a Board  meeting  that he will step down as  Chairman of the Board and
not run for  reelection at the 2003 annual  meeting of  stockholders,  (ii) Dick
Erkeneff will retire as Chief Executive Officer of the Company in July and (iii)
Fred  Strader will be appointed as Chief  Executive  Officer.  We also  strongly
support Fred Strader  being  nominated to fill the vacancy that results from Mr.
Gelb leaving the Board.

            We  remain  committed  to taking  all  action  required  in order to
maximize  value for all  stockholders  and to the  principles of full,  fair and
prompt disclose to all stockholders. We believe each of you should consider your
actions in such light and should  adopt all  proposals  outlined in our April 1,
2003 letter.

                                      Very truly yours,
