10:40 AM EDT. A copy of the Company’s presentation will be accessible on the
Abraxas website at www.abraxaspetroleum.com.

Bob Watson, President and CEO of Abraxas, commented, “Activity levels remain
strong at Abraxas. In the Eagle Ford, we are eager to see how our first long
lateral the Sting Ray A 1H performs. Moreover, our forty-acre spacing test at
WyCross on the Camaro B 4H and Camaro B 3H, if successful, carries with it
significant reserve and inventory implications. The upcoming four well
completion on the Lillibridge East PAD promises to provide a significant boost
to volumes. As previously announced, we will be walking the rig to the
Lillibridge West PAD in an effort to avoid any potential road ban delays. We
look forward to updating the market in the near future post these
