Item 1.01 Entry into a Material Definitive Agreement

     Agreements Related to Grey Wolf Exploration Inc.'s Initial Public Offering.
     --------------------------------------------------------------------------

         As stated in the Current  Report on Form 8-K dated  January 19, 2005 of
Abraxas  Petroleum  Corporation  (the  "Company"),  on  January  18,  2005,  the
Company's  wholly-owned  Canadian subsidiary,  Grey Wolf Exploration Inc. ("Grey
Wolf") filed a preliminary prospectus with the securities regulatory authorities
in each of Canada's  provinces in connection  with an initial public offering of
Grey Wolf's common stock (the "IPO").

         On February 17, 2005, the Company,  Grey Wolf and certain  underwriters
executed an Underwriting Agreement (the "Underwriting  Agreement").  Pursuant to
the Underwriting Agreement, the underwriters have offered to purchase 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 the  Company  (the
"Secondary Shares") from the Company at a purchase price of CDN $2.80 per share,
and  Grey  Wolf  and  the  Company  have  agreed  to  issue  and to  sell to the
underwriters such shares.

         Pursuant to the Underwriting Agreement,  the Company and Grey Wolf have
agreed, jointly and severally, to protect and indemnify each of the underwriters
named in the Underwriting Agreement for certain losses. In connection therewith,
the Company and Grey Wolf entered into a Contribution  Agreement  which provides
that if  either  the  Company  or Grey  Wolf or  both of them  are  required  to
indemnify  or  make  contribution  to any  underwriter  under  the  Underwriting
Agreement, then the Company and Grey Wolf will contribute to the indemnification
amount required to be paid in proportion to the amount of net proceeds  received
by each of them in the IPO.

         The  Company has also  granted to the  underwriters  an  over-allotment
option to purchase from the Company,  at the  underwriters'  election,  up to an
additional  3,902,360  shares of Grey Wolf common stock held by the Company (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  anticipates  using
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 the
Company.  The Company  anticipates using the $1million  received from Grey Wolf,
the proceeds  received from the sale of the Secondary  Shares,  and any proceeds
from  the  sale of  shares  pursuant  to the  over-allotment  option  to  re-pay
outstanding  debt under its $25 million  bridge loan.  The sales of the Treasury
Shares and the  Secondary  Shares are  expected to be  completed on February 28,
2005.

         In connection with the IPO, the Company entered into several definitive
agreements in anticipation  of separating  Grey Wolf's  operations from those of
the  Company.  These  agreements  include:  (i) an  amendment  to the  Company's
employment  agreement with Robert L.G. Watson, (ii) a related Corporate Services
Agreement  between  the  Company  and Grey Wolf,  (iii) an  Indemnity  Agreement
between the Company and Grey Wolf and (iv) a  Non-competition  Agreement between
the Company and Grey Wolf.

         Both the  amendment  to the  Company's  employment  agreement  with Mr.
Watson and the Corporate Services  Agreement address Mr. Watson's  continuing to
act as the Chief  Executive  Officer  and  President  for the Company and as the
Chief Executive Officer for Grey Wolf. Upon consummation of the IPO, the parties
have agreed that Mr. Watson will devote  two-thirds of his time to his positions
and duties  with the  Company  and the  remaining  one-third  of his time to his
positions  and duties  with Grey Wolf.  Grey Wolf has agreed to pay the  Company
USD$120,000  per year for Mr.  Watson's  services,  together with  out-of-pocket
third  party  expenses  reasonably  incurred by the  Company in  providing  such
services.  Either the Company or Grey Wolf may terminate the Corporate  Services
Agreement upon 60 days prior written notice,  or immediately upon certain events
of default,  including  events related to the filing of bankruptcy or insolvency
proceedings or the determination that a party is bankrupt, Mr. Watson ceasing to
be at least one of either  the CEO,  President  or other  position  in Grey Wolf
acceptable to the Company, Grey Wolf and Mr. Watson, or Mr. Watson ceasing to be
an employee or director of the Company.

         The Company has also agreed to indemnify  and hold  harmless  Grey Wolf
and each of its  directors,  officers,  employees  and  agents  for any  losses,
expenses,  claims, damages and liabilities related to an indemnity provided in a
Guarantee  given to  PrimeWest  dated  February  23,  2003,  whereby  Grey  Wolf
guaranteed the prompt payment and performance to PrimeWest of all  indebtedness,
liabilities  and  obligations  which  PrimeWest,  PrimeWest  Energy Inc. and the

                                       2


Company  incurred or may incur under a Purchase and Sale  Agreement  dated as of
November 21, 2002 and certain  documents  related  thereto.  The Company has the
right to defend any claim on behalf of an indemnified party; provided,  however,
that it may not settle,  enter into any judgment concerning or otherwise seek to
terminate any claim without Grey Wolf's consent.

         Upon  consummation  of the  IPO  and  pursuant  to the  Non-competition
Agreement,  the  Company has agreed that until 180 days after the earlier of Mr.
Watson's no longer being an  affiliate of the Company or Grey Wolf,  the Company
will not acquire,  manage,  hold,  operate or own,  directly or indirectly,  any
petroleum or natural gas rights  anywhere  outside the United States of America.
Similarly,  Grey Wolf has agreed  that for the same term,  it will not  acquire,
manage,  hold, operate or own, directly or indirectly,  any petroleum or natural
gas rights  anywhere  inside the United States of America.  The  Non-competition
agreement provides exceptions for passive investments of up to 10% in any public
entity's securities and for certain incidental acquisitions.

     Bonus Grant to Robert L.G. Watson, the Company's CEO and President.
     ------------------------------------------------------------------

         In connection with the Company's January 2003 financial  restructuring,
certain  former  noteholders  had required that the Company  re-price all of its
outstanding  stock options to $0.66 per share,  except for those options held by
Mr. Watson.  Only one-half of Mr.  Watson's  options were so re-priced.  At that
time,  the former  noteholders  gave the Company the discretion to grant certain
options to purchase the  Company's 11 1/2%  secured  notes due 2007,  which were
being issued in connection with the January 2003 financial restructuring, to Mr.
Watson.  The Board  determined that it would not be in the best interests of the
Company  and its  stockholders  to grant the note  options to Mr.  Watson as the
notes  issuable  pursuant to the note options would have increased the Company's
indebtedness  and the Board believed that the issuance of the note options would
have created a conflict of interest for Mr. Watson as his  interests  could have
been seen to be aligned  with those of the  noteholders  rather than solely with
the  shareholders  of the Company.  In October  2004,  the Company  successfully
completed a  recapitalization  that included the  redemption of the Company's 11
1/2 % secured notes due 2007. After the conclusion of the 2004 refinancing,  the
Board and Mr. Watson  engaged in a dialogue  regarding a potential  bonus to Mr.
Watson relating to the successful completion of the refinancing.  Based upon the
foregoing,  on February 16, 2005,  the Board  approved the payment of a one-time
discretionary  bonus to Mr. Watson of $490,000 for his  leadership in concluding
the Company's  October 2004 refinancing as well as the completion of the initial
public  offering by Grey Wolf discussed  above.  In determining the amount to be
paid to Mr. Watson,  the Board  considered the potential value that Mr. Watson's
shares  would  have  had if  all  of  his  stock  options  had  been  re-priced,
approximately $490,000, in January 2003.
