     As set forth in the Offer to Exchange  dated  December , 2004 (as it may be
supplemented from time to time, the "Offer") of Abraxas Petroleum Corporation, a
Nevada corporation ("Abraxas" or the "Company"), this Letter of Transmittal (the
"Letter of Transmittal" and, together with the Offer, the "Exchange Offer") must
be used to tender the  Outstanding  Notes in response to the Company's  offer to
exchange $125,000,000 principal amount of Floating Rate Senior Secured Notes due
2009, Series B (the "Exchange  Notes"),  for all Outstanding Notes tendered,  if
(i) certificates  representing  Outstanding Notes are to be physically delivered
to the Exchange Agent herewith by such  Noteholders;  (ii) tender of Outstanding
Notes is to be made by book-entry  transfer to the Exchange  Agent's  account at
The Depository  Trust Company ("DTC") pursuant to the procedures set forth under
the caption "The Series A/B Exchange Offer--Procedures for Tendering Outstanding
Notes--Valid Tender" in the Offer; or (iii) tender of Outstanding Notes is to be
made according to the guaranteed delivery procedures set forth under the caption
"The  Series  A/B   Exchange   Offer--Procedures   for   Tendering   Outstanding

     Noteholders  that are  tendering  by  book-entry  transfer to the  Exchange
Agent's  account  at DTC can  execute  the  tender  through  ATOP for  which the
transaction will be eligible.  DTC participants  that are accepting the Exchange
Offer must transmit  their  acceptance to DTC,  which will verify the acceptance
and execute a book-entry  delivery to the Exchange  Agent's  account at DTC. DTC
will then send an agent's  message  to the  Exchange  Agent for its  acceptance.

Offer as to execution and delivery of a Letter of Transmittal by the participant
identified in the agent's message. DTC participants may also accept the Exchange
Offer by submitting a notice of guaranteed delivery through ATOP.

     If  a  Noteholder   desires  to  tender  Outstanding  Notes  and  (i)  such
Outstanding Notes are not lost but are not immediately available, (ii) time will
not permit the  Noteholder's  Outstanding  Notes or other required  documents to
reach the Exchange Agent before the Expiration Time, or (iii) the procedures for
book-entry  transfer  cannot be  completed  on a timely  basis,  a tender may be
effected if the following conditions are satisfied:

         o     the tender is made by or through an Eligible Institution;

         o     prior to the  Expiration  Time,  the Exchange Agent receives from
               the  Eligible   Institution  a  properly   completed   Notice  of
               Guaranteed  Delivery  (by  facsimile  transmission,  mail or hand
               delivery)  substantially  in the form the Company  provides which
               sets forth the name and address of the  Noteholder and the amount
               of the Outstanding Notes tendered; and

         o     a Letter of Transmittal (or a manually signed facsimile thereof),
               properly   completed  and  validly  executed  with  any  required
               signature  guarantees,  or, in the case of a book-entry transfer,
               an  agent's   message,   together  with   certificates   for  all
               Outstanding  Notes in proper form for  transfer  (or a book-entry
               confirmation with respect to all tendered Outstanding Notes), and
               any other  required  documents are received by the Exchange Agent
               within  three  business  days after the date of  execution of the

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     The undersigned hereby tender(s) to Abraxas,  upon the terms and subject to
the conditions set forth in the Offer,  receipt of which is hereby acknowledged,
and in  accordance  with this Letter of  Transmittal,  the  principal  amount of
Outstanding  Notes  indicated  in  the  table  above  entitled  "Description  of
Outstanding  Notes  Tendered"  under the  column  heading  "Principal  Amount of
Outstanding  Notes  Tendered" in exchange for the Exchange  Notes.  The Exchange
Notes  evidence the same debt as the  Outstanding  Notes  (which they  replace).
Capitalized terms used but not defined herein have the respective meanings given
such  terms  in  the  Offer.  The  undersigned   understand(s)  that  tender  of
Outstanding Notes may not be withdrawn except under the circumstances  described
in the Offer.

     Subject to, and effective upon, the acceptance for purchase of, and payment
for, the principal amount of Outstanding  Notes tendered  herewith in accordance
with the  terms  and  subject  to the  conditions  of the  Exchange  Offer,  the
undersigned hereby sell(s),  assign(s) and transfer(s) to, or upon the order of,
the  Company,  all right,  title and  interest in and to all of the  Outstanding
Notes tendered hereby.  The undersigned  hereby  irrevocably  constitute(s)  and
appoint(s)  the  Exchange  Agent as true and lawful  agent and  attorney-in-fact
(with  full  knowledge  that the  Exchange  Agent  also acts as the agent of the
Company)  with  respect  to  such  Outstanding   Notes,   with  full  powers  of
substitution  and  revocation  (such  power of  attorney  being  deemed to be an
irrevocable  power  coupled with an  interest)  to (i) present such  Outstanding
Notes and all evidences of transfer and authenticity  to, or transfer  ownership
of, such  Outstanding  Notes on the account books  maintained by DTC to, or upon
the order of, the Company,  (ii) present such Outstanding  Notes for transfer of
ownership  on the books of the  Company,  and (iii)  receive  all  benefits  and
otherwise exercise all rights of beneficial ownership of such Outstanding Notes,
all in  accordance  with the  terms  and  conditions  of the  Exchange  Offer as
described in the Offer.

     In the event of a termination of the Exchange Offer, the Outstanding  Notes
tendered  pursuant  to the  Exchange  Offer will be  returned  to the  tendering
Noteholders  promptly  (or,  in  the  case  of  Outstanding  Notes  tendered  by
book-entry  transfer,  such  Outstanding  Notes will be  credited to the account
maintained  at DTC from which such  Outstanding  Notes were  delivered).  If the
Company  reduces the principal  amount of the Exchange Notes to be exchanged for
the Outstanding Notes,  reduces the principal amount of the notes subject to the
Exchange Offer or is otherwise required by law to permit withdrawal, the Company
will  disseminate  additional  Exchange Offer materials and extend such Exchange
Offer to the extent required by law.

     The undersigned  understand(s) that tender of Outstanding Notes pursuant to
any of the procedures  described in the Offer and in the instructions hereto and
acceptance of such  Outstanding  Notes by the Company will  constitute a binding
agreement  between the undersigned and the Company upon the terms and subject to
the conditions of the Exchange Offer.  For purposes of the Exchange  Offer,  the
undersigned   understand(s)   that  validly  tendered   Outstanding   Notes  (or
defectively  tendered  Outstanding  Notes with  respect to which the Company has
waived such defect,  or has caused such defect to be waived),  will be deemed to
have been  accepted by the  Company  if, as and when the  Company  gives oral or
written notice thereof to the Exchange Agent.

         The undersigned hereby represent(s) and warrant(s) that it has full
power and authority to tender, exchange, sell, assign and transfer the
Outstanding Notes tendered hereby, and that when such tendered Outstanding Notes
are accepted for purchase and payment by the Company, the Company will acquire
good, marketable and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claim,
right or proxy. The undersigned will, upon request, execute and deliver any
additional documents deemed by the Exchange Agent or the Company to be necessary
or desirable to complete the sale, exchange, assignment and transfer of the
Outstanding Notes tendered hereby.

                                       5


     All  authority  conferred  or  agreed  to be  conferred  by this  Letter of
Transmittal shall not be affected by, and shall survive, the undersigned's death
or incapacity,  and any obligation of the undersigned hereunder shall be binding
upon the heirs, executors, administrators,  trustees in bankruptcy, personal and
legal representatives, successors and assigns of the undersigned.

     The  undersigned  understand(s)  that the  delivery  and  surrender  of any
Outstanding  Notes is not  effective,  and the  risk of loss of the  Outstanding
Notes does not pass to the Exchange  Agent,  until receipt by the Exchange Agent
of this Letter of Transmittal (or a manually signed facsimile hereof),  properly
completed  and duly  executed,  together  with  all  accompanying  evidences  of
authority and any other required  documents in form satisfactory to the Company.
All questions as to the form of all documents and the validity  (including  time
of receipt) and acceptance of tenders and withdrawals  will be determined by the
Company, in its sole discretion, which determination shall be final and binding.
For purposes of the Exchange Offer,  the Company will be deemed to have accepted
validly tendered  Outstanding  Notes if and when the Company gives notice to the
Exchange Agent.

     The undersigned  understand(s) that notwithstanding any other provisions of
the  Exchange  Offer  to the  contrary,  delivery  of  the  Exchange  Notes  for
Outstanding Notes accepted for tender pursuant to the Exchange Offer will in all
cases  be  made  only  after  timely  receipt  by  the  Exchange  Agent  of  (a)
certificates  for (or a timely  book-entry  confirmation  with  respect to) such
Outstanding  Notes,  (b) a Letter of Transmittal (or a manually signed facsimile
thereof),  properly completed and validly executed,  with any required signature
guarantees,  or, in the case of a book-entry  transfer,  an agent's message, and
(c) any other documents required by the applicable Letter of Transmittal and the
instructions thereto. Accordingly,  tendering Noteholders whose certificates for
Outstanding  Notes or book-entry  confirmation  with respect to such Outstanding
Notes are actually  received by the Exchange Agent after the Expiration Time may
be paid later than other  tendering  Noteholders.  Under no  circumstances  will
interest be paid on the Exchange Notes to be paid by the Company  because of any
delay in making such delivery or otherwise.

     Unless  otherwise   indicated   herein  under  "Special   Issuance/Delivery
Instructions," the undersigned hereby request(s) that the Exchange Notes and any
Outstanding  Notes  representing  principal amounts not tendered or not accepted
for purchase be issued in the name(s) of, and delivered to, the  undersigned  at
the address  indicated under  "Description of Outstanding  Notes Tendered" above
(and in the case of Outstanding Notes tendered by book-entry transfer, by credit
to the account of DTC).

     In the  event  that the  "Special  Issuance/Delivery  Instructions"  box is
completed,  the  undersigned  hereby  request(s) that the Exchange Notes and any
Outstanding  Notes  representing  principal amounts not tendered or not accepted
for purchase be issued in the name(s) of, and be delivered  to, the person(s) at
the address(es) therein indicated. The undersigned recognize(s) that the Company
has no obligation pursuant to the "Special  Issuance/Delivery  Instructions" box
to transfer any Outstanding Notes from the names of the registered Noteholder(s)
thereof if the Company does not accept for purchase any of the principal  amount
of such Outstanding Notes so tendered.

     1. Signature  Guarantees.  Signatures on this Letter of Transmittal must be
guaranteed by an Eligible  Institution,  unless the  Outstanding  Notes tendered

of an Eligible Institution.  If the Outstanding Notes are registered in the name
of a  person  other  than  the  signer  of  this  Letter  of  Transmittal  or if
Outstanding Notes not accepted for payment or not tendered are to be returned to
a person  other than the  registered  Noteholder,  then the  signatures  on this

agent's message,  together with certificates for all Outstanding Notes in proper
form for  transfer (or a  book-entry  confirmation  with respect to all tendered
Outstanding  Notes), and any other required documents within three business days
after the date of execution of the Notice of Guaranteed Delivery.

     The method of delivery of this Letter of Transmittal, the Outstanding Notes
and  all  other  required  documents,  including  delivery  through  DTC and any
acceptance of agent's message  delivered through ATOP, is at the option and risk
of the tendering Noteholder.  Instead of delivery by mail, we recommend that the
undersigned  use(s) an overnight  or hand  delivery  service.  If delivery is by
mail,  registered  mail with return  receipt  requested,  properly  insured,  is
recommended.  In all cases, sufficient time should be allowed for such documents
to reach the Exchange  Agent prior to the Expiration  Time.  Except as otherwise
provided in this  Instruction 2, delivery will be deemed made only when actually
received by the Exchange Agent.

                                       9


     No  alternative,  conditional or contingent  tenders will be accepted.  All
tendering  Noteholders,  by  execution  of  this  Letter  of  Transmittal  (or a
facsimile  thereof),  waive any right to receive any notice of the acceptance of
their Outstanding Notes for payment.

     3.  Inadequate  Space.  If the space  provided  herein is  inadequate,  the
certificate numbers and/or the principal amount represented by Outstanding Notes
should be listed on a separate signed schedule attached hereto.

     4.  Signatures  on Letter  of  Transmittal,  Instruments  of  Transfer  and
Endorsements.  If  this  Letter  of  Transmittal  is  signed  by the  registered
Noteholder(s) of the Outstanding  Notes tendered hereby,  the signature(s)  must
correspond with the name(s) as written on the face of the certificate(s) without
alteration,  enlargement or any change whatsoever. If this Letter of Transmittal
is  signed  by a  participant  in DTC  whose  name is shown as the  owner of the
Outstanding  Notes tendered hereby,  the signature must correspond with the name
shown on the security position listing as the owner of the Outstanding Notes.

     If any of the Outstanding  Notes tendered hereby are registered in the name
of two or more  Noteholders,  all such  Noteholders  must  sign  this  Letter of
Transmittal.  If any of the Outstanding  Notes tendered hereby are registered in
different names on several certificates,  it will be necessary to complete, sign
and  submit as many  separate  Letters  of  Transmittal  as there are  different
registrations of certificates.

     If this Letter of  Transmittal  or any  Outstanding  Notes or instrument of
transfer   is  signed  by  a   trustee,   executor,   administrator,   guardian,
attorney-in-fact,  agent,  officer of a corporation  or other person acting in a
fiduciary  or  representative  capacity,  such person  should so  indicate  when
signing,  and proper  evidence  satisfactory  to the  Company  of such  person's
authority to so act must be submitted.

     When this Letter of Transmittal is signed by the registered  Noteholders of
the  Outstanding  Notes  listed  and  transmitted  hereby,  no  endorsements  of
Outstanding  Notes or separate  instruments  of  transfer  are  required  unless
payment is to be made, or Outstanding  Notes not tendered or purchased are to be
issued,  to a  person  other  than the  registered  Noteholders,  in which  case
signatures  on  such  Outstanding  Notes  or  instruments  of  transfer  must be
guaranteed by a recognized member of the Medallion Signature Guarantee Program.

     If this  Letter of  Transmittal  is  signed  other  than by the  registered
Noteholders  listed,  the  Outstanding  Notes must be endorsed or accompanied by
appropriate  instruments of transfer,  in either case signed exactly as the name
or names of the  registered  Noteholders  appear  on the  Outstanding  Notes and
signatures on such Outstanding Notes or instruments of transfer are required and
must be guaranteed by an Eligible Institution.

     5.  Special  Issuance  and  Delivery  Instructions.   If  certificates  for
unpurchased  or untendered  Outstanding  Notes are to be issued in the name of a
person  other  than  the  signer  of  this  Letter  of  Transmittal,  or if such
Outstanding  Notes are to be returned  to someone  other than the signer of this
Letter of  Transmittal  or to an  address  other  than  that  shown  above,  the
appropriate  "Special  Issuance/Delivery  Instructions"  boxes on this Letter of
Transmittal  should be completed.  All Outstanding  Notes tendered by book-entry
transfer and not accepted for payment will be returned by crediting  the account
at DTC  designated  above as the account for which such  Outstanding  Notes were
delivered or by sending certificates for such Outstanding Notes to the tendering
Noteholder, as applicable.

     6. Transfer Taxes.  Except as set forth in this  Instruction 6, the Company
will pay or cause to be paid any transfer taxes with respect to the transfer and
sale of  Outstanding  Notes to it, or to its  order,  pursuant  to the  Exchange
Offer.  If payment  of the  Exchange  Notes is to be made to, or if  Outstanding
Notes not tendered or purchased are to be registered in the name of, any persons
other  than  the  registered  owners,  or  if  tendered  Outstanding  Notes  are
registered in the name of any persons other than the persons signing this Letter
of  Transmittal,  the  amount of any  transfer  taxes  (whether  imposed  on the
registered  Noteholder or such other person)  payable on account of the transfer
to  such  other  person  shall  be  deducted  from  the  Exchange  Notes  unless
satisfactory  evidence of the payment of such taxes or  exemption  therefrom  is
submitted.

                                       10


     7.  Waiver of  Conditions.  The  conditions  of the  Exchange  Offer may be
amended or waived by the Company, in whole or in part, at any time and from time
to time in the Company's sole discretion,  in the case of any Outstanding  Notes
tendered.

     8.  Substitute  Form W-9.  Each  tendering  Noteholder  (or other payee) is
required to provide the Exchange  Agent with a correct  taxpayer  identification
number ("TIN"),  generally the Noteholder's  Social Security or federal employer
identification  number, and with certain other  information,  on Substitute Form
W-9, which is provided under "Important Tax  Information"  below, and to certify
that the  Noteholder  (or other  payee) is not  subject  to backup  withholding.
Failure to provide the  information on the  Substitute  Form W-9 may subject the
tendering  Noteholder (or other payee) to a $50 penalty  imposed by the Internal
Revenue Service and 28% federal income tax backup  withholding on the payment of
the Exchange Notes.  The box in Part 3 of the Substitute Form W-9 may be checked
if the tendering  Noteholder  (or other payee) has not been issued a TIN and has
applied for a TIN or intends to apply for a TIN in the near  future.  If the box
in Part 3 is checked and the Exchange  Agent is not  provided  with a TIN by the
time of payment,  the Exchange  Agent will  withhold 28% on all such payments of
the Exchange Notes until a TIN is provided to the Exchange Agent.

     9. Requests for Assistance or Additional  Copies. Any questions or requests
for assistance or additional  copies of the Offer, this Letter of Transmittal or
the Notice of Guaranteed Delivery,  may be directed to the Exchange Agent at the
telephone  number and location  listed above. A Noteholder may also contact such
Noteholder's  broker,  dealer,  commercial  bank or trust company or nominee for
assistance concerning the Exchange Offer.

     IMPORTANT:  This Letter of Transmittal  (or a facsimile  hereof),  together
with  Outstanding  Notes  and all  other  required  documents  or the  Notice of
Guaranteed  Delivery,  must be received by the Exchange Agent at or prior to the
Expiration Time in order to receive the Exchange Notes.

                            IMPORTANT TAX INFORMATION

     Under federal income tax law, a Noteholder whose tendered Outstanding Notes
are accepted  for payment or exchange is required to provide the Exchange  Agent
with  such  Noteholder's  current  TIN on  Substitute  Form W-9  below.  If such
Noteholder is an individual,  the TIN is his or her Social Security  number.  If
the Exchange Agent is not provided with the correct TIN, the Noteholder or other
payee may be subject to a $50 penalty imposed by the Internal  Revenue  Service.
In addition,  any  Exchange  Notes paid to such  Noteholder  or other payee with
respect to  Outstanding  Notes  pursuant to the Exchange Offer may be subject to
28% backup withholding tax.

     Certain Noteholders (including,  among others, all corporations and certain
foreign  individuals) are not subject to these backup  withholding and reporting
requirements.  In  order  for a  foreign  individual  to  qualify  as an  exempt
recipient,  that  Noteholder  must  submit  to the  Exchange  Agent  a  properly
completed Internal Revenue Service Form W-8BEN, Certificate of Foreign Status of
Beneficial Owner for United States Tax Withholding, (a "Form W-8"), signed under
penalties of perjury,  attesting to that individual's  exempt status. A Form W-8
can be obtained from the Exchange Agent.

     If backup withholding  applies,  the Exchange Agent is required to withhold
28% of any  Exchange  Notes  paid  to the  Noteholder  or  other  payee.  Backup
withholding is not an additional tax.  Rather,  the federal income tax liability
of persons  subject to backup  withholding  will be reduced by the amount of tax
withheld.  If  withholding  results in an  overpayment of taxes, a refund may be
obtained from the Internal Revenue Service.



                                       11


Purpose of Substitute Form W-9

     To prevent backup withholding on any Exchange Notes paid to a Noteholder or
other payee with respect to Outstanding Notes purchased pursuant to the Exchange
Offer,  the  Noteholder  is  required  to  notify  the  Exchange  Agent  of  the
Noteholder's  current TIN (or the TIN of any other payee) by completing the form
below,  certifying  that the TIN provided on Substitute  Form W-9 is correct (or
that such  Noteholder is awaiting a TIN),  and that (i) the  Noteholder  has not
been notified by the Internal  Revenue Service that the Noteholder is subject to
backup withholding as a result of failure to report all interest or dividends or
(ii)  the  Internal  Revenue  Service  has  notified  the  Noteholder  that  the
Noteholder is no longer subject to backup withholding.

What Number to Give the Exchange Agent

     The Noteholder is required to give the Exchange Agent the TIN (e.g., Social
Security  number or Employer  Identification  Number) of the record owner of the
Outstanding Notes.

Certificate of Awaiting Taxpayer Identification Number

     If the tendering Noteholder has not been issued a TIN and has applied for a
number  or  intends  to apply  for a number  in the near  future,  check the box
"Awaiting TIN" provided in Part 2 on Substitute Form W-9, sign and date the form
and the Certificate of Awaiting Taxpayer  Identification  Number and return them
to the Exchange Agent.  If such  certificate is completed and the Exchange Agent
is not provided  with the TIN within 60 days,  the Exchange  Agent will withhold
28% of all  payments  made  thereafter  until a TIN is provided to the  Exchange
Agent.
