Item 2.01 Completion of Acquisition or Disposition of Assets

     On February 28, 2005, Abraxas Petroleum Corporation  substantially divested
its  investment  in Grey Wolf  Exploration,  Inc.  Pursuant  to an  Underwriting
Agreement,  the  underwriters  purchased  17,800,000  common shares of Grey Wolf
capital stock from Grey Wolf (the "Treasury  Shares"),  and 9,100,000  shares of
Grey Wolf common stock owned by Abraxas (the "Secondary Shares") from Abraxas at
a purchase price of CDN $2.80 per share.

     Abraxas  also  granted  to the  underwriters  an  over-allotment  option to
purchase  from  Abraxas,  at the  underwriters'  election,  up to an  additional
3,902,360  shares  of Grey  Wolf  common  stock  held by  Abraxas  (the  "Option
Shares").  The over-allotment option may be exercised in whole or in part at any
one time prior to 5:00 p.m.,  Calgary time,  on the day that is thirty  calendar
days after the closing date for the IPO.  Grey Wolf  utilized the proceeds  from
the sale of the  Treasury  Shares to re-pay and  terminate  its $35 million term
loan and re-pay $1 million in  inter-company  debt to Abraxas.  Abraxas utilized
the $1million received from Grey Wolf and the proceeds received from the sale of
the Secondary  Shares to re-pay  outstanding  debt under its $25 million  bridge
loan.  After  consummation  of the offering,  Abraxas'  remaining debt under the
bridge loan was $5.4 million, before the sale of the 3,902,360 Option Shares.


Item 9.01 Financial Statements and Exhibits

         (b) Pro forma financial information



                    UNAUDITED PRO FORMA FINANCIAL INFORMATION

     The pro forma  financial  data  presented  below is unaudited  and has been
derived from our consolidated financial statements and from unaudited historical
and pro forma consolidated  financial data. The pro forma financial  information
presented  below for the year ended  December  31,  2003 and for the nine months
ended  September 30, 2004  reflects  consolidated  statement of operations  data
relating to Abraxas and gives effect to:

     o   the exclusion of Grey Wolf from Abraxas' statement of operations;

     o   the consummation of the October 2004 financial restructuring; and

     o   the exclusion of the January 2003 financial restructuring.

     The pro forma  condensed  balance sheet reflects the  consolidated  balance
sheet data relating to Abraxas and gives effect to:

     o   the  exclusion  of  balance  sheet  data  relating  to Grey  Wolf as of
         September 30, 2004.

     o   the impact of the Grey Wolf IPO on  February  28,  2005  including  the
         effect of the sale of the 3,902,360 Option Shares.

     Grey Wolf, through which we conducted our Canadian  operations and held our
properties and assets located in Canada,  is excluded from the pro forma results
due to the  consummation  of Grey Wolf's initial public offering on February 28,
2005.  Approximately  87% of the Company's  investment in Grey Wolf was divested
and the Company  plans to divest the remaining  13% of its  investment  over the
next  several  months.  The  accompanying  pro forma  financial  information  is
presented as if the Secondary Shares and the Option Shares (representing 100% of
Abraxas' investment in Grey Wolf) has been divested.

     The pro forma information set forth below is not necessarily  indicative of
the results that actually  would have been achieved if the Grey Wolf  operations
had not been part of Abraxas' operations or the refinancing had been consummated
as of the dates indicated.
