Item 1.01 Entry into a Material Definitive Agreement

         See Item  3.02  below  for a  description  of a Common  Stock  Purchase
Agreement  between the Company and certain  accredited  investors  relating to a
private placement of common stock.

Item 3.02  Unregistered Sales of Equity Securities

         On July 20, 2005, Abraxas Petroleum Corporation (the "Company") entered
into a Common Stock Purchase Agreement (the "Agreement") with certain accredited
investors (the  "Purchasers"),  pursuant to which the Company issued 4.0 million
shares of its common stock,  par value $.01 per share (the "Common  Stock"),  to
the  Purchasers at a price of $3.00 per share,  or an aggregate of $12.0 million
in cash before  transaction  expenses.  The Common Stock has not been registered
under the  Securities  Act of 1933, as amended (the  "Securities  Act"),  or any
applicable  state  securities laws in reliance on the exemption  provided by ss.
4(2)  of  the  Securities  Act  and  Rule  506 of  the  regulations  promulgated
thereunder.  The Common  Stock may not be  offered or sold in the United  States
absent   registration   or  an  applicable   exemption  from  the   registration
requirements.  There was no general  solicitation  involved in the offer and the
Common Stock was sold  exclusively  to  accredited  investors  as defined  under
Regulation  D. The Company will pay a five percent (5%) cash  commission  out of
such  proceeds to Energy  Capital  Solutions  LLC which  acted as the  Company's
financial advisor.

         The  Company has agreed,  promptly  following  the Closing but no later
than August 31,  2005,  to prepare  and file with the  Securities  and  Exchange
Commission a  registration  statement on Form S-3 or such other  successor  form
(except  that if the Company is not then  eligible  to  register  for resale the
Common  Stock on Form S-3,  then such  registration  shall be on Form S-1 or any
successor form) (a "Registration  Statement") to enable the resale of the Common
Stock by the Purchasers or their transferees from time to time over the American
Stock  Exchange or any other  national  exchange on which the  Company's  Common
Stock is then traded, or in privately-negotiated  transactions.  The Company has
agreed to use its  commercially  reasonable  efforts to cause such  Registration
Statement  to become  effective  as soon as  practicable  (subject to receipt of
necessary  information from the Purchasers after prompt request from the Company
to the  Purchasers  to  provide  such  information)  and to remain  continuously
effective  for a  period  ending  on the  date  that is,  with  respect  to each
Purchaser's Common Stock purchased pursuant to the Agreement, the earlier of (i)
the date on which the Purchaser may sell all shares of Common Stock then held by
the Purchaser  without  restriction  under Rule 144(k), or (ii) such time as all
shares of Common Stock  purchased by such  Purchaser  pursuant to the  Agreement
have been sold or otherwise transferred pursuant to a registration  statement or
otherwise.

         If the  Registration  Statement  is not declared  effective  within one
hundred twenty (120) days after the Closing Date, the Company shall be obligated
to pay  liquidated  damages in  additional  shares of the  Common  Stock to each
Purchaser of a number of shares  equal to two percent  (2%) of such  Purchaser's
Purchase  Price for Common Stock  purchased at the Closing and then  outstanding
pursuant to the  Agreement  divided by the 10-day  average  closing price of the
Common  Stock prior to the date that the payment is due, and two percent (2%) of
such Purchaser's  Purchase Price for Common Stock purchased and then outstanding
pursuant to the Agreement  divided by the prior 10-day average  closing price of
the Common  Stock prior to the date that the payment is due for each  subsequent
thirty (30) day period (pro rated for such  periods  less than thirty (30) days)
until the Registration  Statement is declared  effective.  However,  in no event
shall the total  number of shares  of Common  Stock  that the  Company  shall be
required to issue pursuant to the Agreement  exceed the maximum number of shares
of Common Stock that the Company can issue without stockholder approval pursuant
to any rule of the American Stock  Exchange,  or any other national  exchange on
which the Company's Common Stock is then traded including,  without  limitation,
Section 713 of the  American  Stock  Exchange  Listing  Standards,  Policies and
Requirements,   subject  to  equitable   adjustments   from  time  to  time  for
stock-splits, stock dividends, combinations, capital reorganizations and similar
events relating to the Common Stock occurring after the date of the Agreement.

         The  foregoing  statements  are  qualified  in  their  entirety  by the
provisions of the Common Stock  Purchase  Agreement  filed as an exhibit to this
report.
