Our Business
 
We are an independent energy company primarily engaged in the development and production of oil and gas. Historically, we have grown through the acquisition and subsequent development and exploitation of producing properties, principally through the redevelopment of old fields utilizing new technologies such as modern log analysis and reservoir modeling techniques as well as 3-D seismic surveys, horizontal drilling and modern completion techniques. As a result of these activities, we believe that we have a number of development opportunities on our properties. In addition, we intend to expand upon our development activities with complementary exploration projects in our core areas of operation. Success in our development and exploration activities is critical in the maintenance and growth of our current production levels and associated reserves.

RISK FACTORS
 An investment in our securities involves a high degree of risk. You should carefully consider the risk factors and all of the other information included in, or incorporated by reference into, this prospectus, including those included in our most recent Annual Report on Form 10-K and, if applicable, in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, in evaluating an investment in our securities. If any of these risks were to occur, our business, financial condition or results of operations could be adversely affected. In that case, the trading price of our securities could decline and you could lose all or part of your investment. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

USE OF PROCEEDS
Unless we specify otherwise in the applicable prospectus supplement, the net proceeds we receive from the sale of the securities offered by this prospectus and any prospectus supplement will be used for general corporate purposes.  General corporate purposes may include any of the following:
·  repaying debt;
·  providing working capital;
·  funding capital expenditures; or
·  paying for possible acquisitions or the expansion of our business.
We may temporarily invest the net proceeds we receive from any offering of securities or use the net proceeds to repay short-term debt until we can use them for their stated purposes.
DILUTION
Our net tangible book value at December 31, 2008, we had 25,116 MBoe2012 was $0.50 per share of estimated net proved reserves,common stock.  Net tangible book value per share of which 28% were oil, with a standardized measure of $152.0 million. Our net proved reserves as of December 31, 2008 were 54% proved developed and 46% proved undeveloped. At December 31, 2008, we owned an average working interest of 23.7% in 1,811 producing wells that produced 1,607 net MBoe during 2008. We have identified numerous drilling locations, of which 163 were classified as proved undeveloped as of December 31, 2008, which we believe provides us with a multi-year inventory of drilling opportunities.
Recent Developments
Merger Agreement

We refer to this merger as the Merger. Under the terms of the Merger Agreement, at the effective time of the Merger on October 5, 2009, which we refer to as the Effective Time, the common units of Abraxas Energy not owned by Abraxas Petroleum and its subsidiaries were converted into the right to receive 4.25 shares of Abraxas Petroleum common stock for each Abraxas Energy common unit not ownedis determined by Abraxas Petroleum or its subsidiaries. We issued adividing our tangible net worth, which is tangible assets less liabilities, by the total number of 26,174,061 shares of our common stock outstanding.  If we offer shares of our common stock, purchasers of our common stock in that offering may experience immediate dilution in net tangible book value per share.  The prospectus supplement relating to an offering of shares of our common stock will set forth the information regarding any dilutive effect of that offering.

Unless otherwise indicated in the applicable prospectus supplement, the debt securities will be our direct, unsecured obligations.  The senior debt securities will rank equally with all of our other senior and unsubordinated debt.  The subordinated debt securities will have a junior position to certain of our debt, as described in the subordinated securities themselves or under the supplemental indenture under which they are issued.
We conduct some of our operations through our subsidiaries.  To the extent of such operations, holders of debt securities will have a position junior to the prior claims of creditors of our subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities and guarantee holders, and any preferred stockholders, except to the extent that we may ourself be a creditor with recognized and unsubordinated claims against any subsidiary.
If specified in the prospectus supplement, the debt securities will be general obligations of our subsidiaries that execute subsidiary guarantees.  Unless otherwise specified in the prospectus supplement, such subsidiary guarantees will be unsecured obligations.  See “– Subsidiary Guarantees.”
A prospectus supplement and a supplemental indenture relating to any series of debt securities being offered will include specific terms relating to the offering.  These terms will include some or all of the following:
·  the title and type of the debt securities;
·  any limit upon the total principal amount of the debt securities;
·  the dates on which the principal and premium (if any) of the debt securities will be payable;
·  the interest rate or rates, or the method of determination thereof, that the debt securities will bear and the interest payment dates for the debt securities;
·  places where payments of the principal, premium, if any, and interest may be made on the debt securities;
·  any optional redemption periods;
·  any subordination and the terms thereof;
·  any sinking fund, amortization or other provisions that would obligate us to redeem, repurchase or repay some or all of the debt securities;
3
·  if other than US dollars, the currency or currencies, or the form of other securities or property in which principal of (and premium, if any) and/or interest on the debt securities will or may be payable;
·  any index or other method used to determine the amount of payment of principal of (and premium, if any) and/or interest on the debt securities;
·  whether any portion of the principal amount of such debt securities is payable upon declaration of the acceleration of the maturity thereof;
·  any additional means of satisfaction or discharge of the debt securities;
·  whether our subsidiaries will provide guarantees of the debt securities, and the terms of any subordination of such guarantee;
·  whether the debt securities will be secured or unsecured;
·  any deletions, modifications, or additions to the events of default or covenants pertaining to the debt securities or made for the benefit of the holders thereof;
·  whether the debt securities will be convertible or exchangeable and, if so, the provisions regarding convertibility or exchangeability of the debt securities;
·  whether the debt securities will be subject to certain optional interest rate reset provisions;
·  whether the debt securities will be issued as a global debt security and, in that case, the identity of the depository for the debt securities; and
·  any other terms of the debt securities.
Neither of the indentures limits the amount of debt securities that may be issued.  Each indenture allows debt securities to be issued up to the principal amount that may be authorized by us and may be in any currency or currency unit designated by us.
Debt securities of a series may be issued in registered, bearer, coupon or global form.
The prospectus supplement for each series of debt securities will state whether the debt securities will be issued in registered form and whether the debt securities will be in denominations other than $1,000 each or multiples thereof.
Original Issue Discount
One or more series of debt securities offered by this prospectus may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates.  The federal income tax consequences and special considerations applicable to any series of debt securities generally will be described in the applicable prospectus supplement.
Subsidiary Guarantees
Our payment obligations under any series of the debt securities may be jointly and severally guaranteed by one or more of our subsidiaries.  If a series of debt securities is so guaranteed by any of our subsidiaries, such subsidiaries will execute a supplemental indenture or notation of guarantee as further evidence of their guarantee.  The applicable prospectus supplement will describe the terms of any guarantee by our subsidiaries. We will file any supplemental indenture or notation of guarantee relating to any guarantees with the Securities and Exchange Commission, and incorporate them by reference as an exhibit to, or incorporated by reference in,  the registration statement of which this prospectus is a part on or before the time such subsidiaries execute a supplemental indenture or notation of guarantee.

The obligations of each subsidiary under its subsidiary guarantee may be limited to the maximum amount that will not result in such guarantee obligations constituting a fraudulent conveyance or fraudulent transfer under federal or state law, after giving effect to all other contingent and fixed liabilities of that subsidiary and any collections from or payments made by or on behalf of any other subsidiary guarantor in respect to its obligations under its subsidiary guarantee.
Each indenture may restrict consolidations or mergers with or into a subsidiary guarantor or provide for the release of a subsidiary from a subsidiary guarantee, as set forth in a related prospectus supplement, the applicable indenture, and any applicable related supplemental indenture.
If a series of debt securities is guaranteed by our subsidiaries and is designated as subordinate to our senior debt, then the guarantee by those subsidiaries will be subordinated to their senior debt and will be subordinated to any guarantees by those subsidiaries of our senior debt.  See “– Subordination.”
Subordination
Under the subordinated indenture, payment of the principal, interest and any premium on the subordinated debt securities will generally be subordinated and junior in right of payment to the prior payment in full of any debt specified in the applicable prospectus supplement and supplemental indenture as being senior to the subordinated debt.
Consolidation, Merger or Sale
The indentures generally permit a consolidation or merger between us and another entity.  They also permit the sale by us of all or substantially all of our property and assets.  If this happens, the remaining or acquiring entity shall assume all of our responsibilities and liabilities under the indentures, including the payment of all amounts due on the debt securities and performance of the covenants in the indentures.  However, we will consolidate or merge with or into any other entity or sell all or substantially all of our assets only according to the terms and conditions of the indentures.  The remaining or acquiring entity will be substituted for us in the indentures with the same effect as if it had been an original party to the indentures.  Thereafter, the successor entity may exercise our rights and powers under any indenture, in our name or in its own name.  Any act or proceeding required or permitted to be done by our board of directors or any of our officers may be done by the board or officers of the successor entity.  If we sell all or substantially all of our assets, upon compliance with these provisions, we shall be released from all of our liabilities and obligations under any indenture and under the debt securities.
Modification of Indentures
Under each indenture our rights and obligations and the rights of the holders may be modified with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected by the modification.  No modification of the principal or interest payment terms, and no modification reducing the percentage required for modifications, is effective against any holder without its consent. Certain of our rights and obligations not having an adverse effect on the rights of the holders may be modified without the consent of the holders of the debt securities.
Events of Default
Each of the indentures defines an event of default with respect to debt securities of any series as any of the following events:
·  failure to pay interest on any debt security for 30 days after it is due;
·  failure to pay the principal of or premium, if any, on any debt security when due;
·  failure to deposit any sinking fund payment for 30 days after it is due;
5
·  failure to perform any other covenant in the indenture that continues for 60 days after being given written notice;
·  certain events of bankruptcy, insolvency or reorganization; or
·  any other event of default included in any indenture or supplemental indenture.
An event of default for a particular series of debt securities does not necessarily constitute an event of default for any other series of debt securities issued under an indenture.  The trustee may withhold notice to the holders of debt securities of any default (except in the payment of principal or interest) if it considers such withholding of notice to be in the best interests of the holders.
If an event of default for any series of debt securities occurs and continues, the trustee or the holders of at least 25% in aggregate principal amount of the debt securities of the series may declare the entire principal of all the debt securities of that series to be due and payable immediately.  If an event of default occurs and is continuing with respect to all series of debt securities as a result of a failure to perform a covenant applicable to all securities or because of bankruptcy, insolvency or reorganization, the trustee or the holders of at least 25% in aggregate principal amount of all of the debt securities may declare the entire principal of all the debt securities to be due and payable immediately.  If either of these events occurs, subject to certain conditions, the holders of a majority of the aggregate principal amount of the debt securities of that series (or of the debt securities of all series, as the case may be) can void the declaration.  There is no automatic acceleration, even in the event of bankruptcy, insolvency or reorganization.
Other than its duties in case of a default, a trustee is not obligated to exercise any of its rights or powers under any indenture at the request, order or direction of any holders, unless the holders offer the trustee reasonable indemnity.  If they provide this reasonable indemnification, the holders of a majority in principal amount of any series of debt securities may direct the time, method and place of conducting any proceeding or any remedy available to the trustee, or exercising any power conferred upon the trustee, for any series of debt securities.
Covenants
Under the indentures, we will:
·  pay the principal of, and interest and any premium on, the debt securities when due;
·  maintain a place of payment;
·  maintain our corporate existence;
·  deliver a report to the trustee at the end of each fiscal year reviewing our obligations under the indentures; and
·  deposit sufficient funds with any paying agent on or before the due date for any principal, interest or premium.
Equal and Ratable Securitization
Neither we nor any restricted subsidiary may secure senior debt securities of any series unless the debt securities of every other series of senior debt securities are also equally and ratably secured.  The subordinated securities have no such restrictive covenant.
Payment and Transfer
Principal, interest and any premium on fully registered securities will be paid at designated places.  Payment will be made by check mailed to the persons in whose names the debt securities are registered on days specified in the indentures or any prospectus supplement.  Debt securities payments in other forms will be paid at a place designated by us and specified in a prospectus supplement.
6
Fully registered securities may be transferred or exchanged at the corporate trust office of the trustee or at any other office or agency maintained by us for such purposes without the payment of any service charge except for any tax or governmental charge.
Global Securities
Certain series of the debt securities may be issued as permanent global debt securities to be deposited with a depositary with respect to that series.  Unless otherwise indicated in the prospectus supplement, the following is a summary of the depository arrangements applicable to debt securities issued in permanent global form and for which The Depositary Trust Company (“DTC”) acts as depositary.
Each global debt security will be deposited with, or on behalf of, DTC, as depositary, or its nominee and registered in the name of a nominee of DTC.  Except under the limited circumstances described below, global debt securities are not exchangeable for definitive certificated debt securities.
Ownership of beneficial interests in a global debt security is limited to institutions that have accounts with DTC or its nominee (“participants”) or persons that may hold interests through participants.  In addition, ownership of beneficial interests by participants in a global debt security will be evidenced only by, and the transfer of that ownership interest will be effected only through, records maintained by DTC or its nominee for a global debt security.  Ownership of beneficial interests in a global debt security by persons that hold through participants will be evidenced only by, and the transfer of that ownership interest within that participant will be effected only through, records maintained by that participant.  DTC has no knowledge of the actual beneficial owners of the debt securities.  Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants through which the beneficial owners entered the transaction.  The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global debt security.
Payment of principal of, and interest on, debt securities represented by a global debt security registered in the name of or held by DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner and holder of the global debt security representing those debt securities.  We have been advised by DTC that upon receipt of any payment of principal of, or interest on, a global debt security, DTC will immediately credit accounts of participants on its book-entry registration and transfer system with payments in amounts proportionate to their respective beneficial interests in the principal amount of that global debt security as shown in the records of DTC.  Payments by participants to owners of beneficial interests in a global debt security held through those participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the sole responsibility of those participants, subject to any statutory or regulatory requirements that may be in effect from time to time.
Neither we, any trustee nor any of our respective agents will be responsible for any aspect of the records of DTC, any nominee or any participant relating to, or payments made on account of, beneficial interests in a permanent global debt security or for maintaining, supervising or reviewing any of the records of DTC, any nominee or any participant relating to such beneficial interests.
A global debt security is exchangeable for definitive debt securities registered in the name of, and a transfer of a global debt security may be registered to, any person other than DTC or its nominee, only if:
·  DTC notifies us that it is unwilling or unable to continue as depositary for that global debt security or at any time DTC ceases to be registered under the Securities Exchange Act of 1934;
·  we determine in our discretion that the global debt security shall be exchangeable for definitive debt securities in registered form; or
·  a supplemental indenture shall so provide.
7
Any global debt security that is exchangeable pursuant to the preceding sentence will be exchangeable in whole for definitive debt securities in registered form, of like tenor and of an equal aggregate principal amount as the global debt security, in denominations specified in the applicable prospectus supplement (if other than $1,000 and integral multiples of $1,000).  The definitive debt securities will be registered by the registrar in the name or names instructed by DTC.  We expect that these instructions may be based upon directions received by DTC from its participants with respect to ownership of beneficial interests in the global debt security.
Except as provided above, owners of the beneficial interests in a global debt security will not be entitled to receive physical delivery of debt securities in definitive form and will not be considered the holders of debt securities for any purpose under the indentures.  No global debt security shall be exchangeable except for another global debt security of like denomination and tenor to be registered in the name of DTC or its nominee.  Accordingly, each person owning a beneficial interest in a global debt security must rely on the procedures of DTC and, if that person is not a participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder under the global debt security or the indentures.
We understand that, under existing industry practices, in the event that we request any action of holders, or an owner of a beneficial interest in a global debt security desires to give or take any action that a holder is entitled to give or take under the debt securities or the indentures, DTC would authorize the participants holding the relevant beneficial interests to give or take that action, and those participants would authorize beneficial owners owning through those participants to give or take that action or would otherwise act upon the instructions of beneficial owners owning through them.
DTC has advised us that DTC is a limited purpose trust company organized under the laws of the State of New York, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Securities Exchange Act of 1934.  DTC was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in those securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates.  DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.  DTC is owned by a number of its participants and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National Association of Securities Dealers, Inc.  Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.  The rules applicable to DTC and its participants are on file with the Securities and Exchange Commission.
Defeasance
We will be discharged from our obligations on the debt securities of any series at any time if we deposit with the trustee sufficient cash or government securities to pay the principal, interest, any premium and any other sums due to the stated maturity date or a redemption date of the debt securities of the series.  If this happens, the holders of the debt securities of the series will not be entitled to the benefits of the indenture except for registration of transfer and exchange of debt securities and replacement of lost, stolen or mutilated debt securities.
We must also obtain an opinion of counsel to the effect that as a result of the defeasance, holders of that series of debt securities will not recognize income, gain or loss for federal income tax purposes and will be subject to federal income tax on the same amount, in the same manner and at the same time as would have been the case if such defeasance had not occurred.
8
Meetings
Each indenture contains provisions describing how meetings of the holders of debt securities of a series may be convened.  A meeting may be called at any time by the trustee, and also, upon request, by us or the holders of at least 20% in principal amount of the outstanding debt securities of a series.  A notice of the meeting must always be given in the manner described under “Notices” below.  Generally speaking, except for any consent that must be given by all holders of a series as described under “Modification of Indentures” above, any resolution presented at a meeting of the holders of a series of debt securities may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series, unless the indenture allows the action to be voted upon to be taken with the approval of the holders of a different specific percentage of principal amount of outstanding debt securities of a series.  In that case, the holders of outstanding debt securities of at least the specified percentage must vote in favor of the action.  Any resolution passed or decision taken at any meeting of holders of debt securities of any series in accordance with the applicable indenture will be binding on all holders of debt securities of that series and any related coupons, unless, as discussed in “Modification of Indentures” above, the action is only effective against holders that have approved it.  The quorum at any meeting called to adopt a resolution, and at any reconvened meeting, will be holders holding or representing a majority in principal amount of the outstanding debt securities of a series.
Governing Law
Each indenture and the debt securities will be governed by and construed in accordance with the laws of the State of New York.
Notices
Notices to holders of debt securities will be given by mail to the addresses of such holders as they appear in the security register.
Credit Facilities
Senior Secured Credit Facility
 
Simultaneous with the closing of the Merger, we entered into an amended and restatedWe have a senior secured credit facility with Société Générale, as administrative agent and issuing lender, and certain other lenders, which we refer to as the new credit facility.  In connection with the Merger, we borrowed approximately $145.0 million under our new credit facility,As of which $135.0December 31, 2012, $113.0 million was borrowedoutstanding under the revolving portion of the new credit facility and $10.0 million

was borrowed under the term loan portion of the new credit facility, and we refinanced and amended and restated all of Abraxas Energy’s existing credit facilities into the new credit facility.
 
The revolving portion of the new credit facility has a maximum commitment of $300.0 million and availability under the revolving portion of the new credit facility will beis subject to a borrowing base. As of December 31, 2012 we had a borrowing base of $150.0 million. In April 2013 this facility was increased to $155.0 million.  Unless redetermined otherwise based on new reserve and production information from the June 30, 2013 engineering report, the borrowing base would reduce to $145 million on October 1, 2013. Management and the bank group anticipate the facility will be redetermined in a timely manner post the Company providing its June 30, 2013 reserve report. The borrowing base under the new credit facility is currently $145.0 million and will be determined semi-annually by the lenders based upon our reserve reports, one of which must be prepared by our independent petroleum engineers and one of which may be prepared internally. The amount of the borrowing base will beis calculated by the lenders based upon their valuation of our provedProved reserves securing the facility utilizing these reserve reports and their own internal decisions. In addition, the lenders, in their sole discretion, will beare able to make one additional borrowing base redetermination during any six-month period between scheduled redeterminations and we will beare able to request one redetermination during any six-month period between scheduled redeterminations.  The lendersborrowing base will also be able to make a redeterminationautomatically reduced in connection with any sales of producing properties with a market value of 5% or more of our then-current borrowing base and in connection with any hedge termination which could reduce the collateral value by 5% or more. Our borrowing base of $145.0was increased to $155.0 million was determined based upon our reserve report dated June 1, 2009.December 31, 2012. Our borrowing base can never exceed the $300.0 million maximum commitment

At October 16, 2009,December 31, 2012, the interest rate on the revolving portion of the new credit facility was 5.75%.
We also borrowed $10.0 million under the term loan portion3.21% based on 1-month LIBOR borrowings and level of the new credit facility at the closing of the Merger. Outstanding amounts under the term loan portion of the new credit facility are expected to bear interest at (a) the greater of (1) the reference rate announced from time to time by Société Générale, (2) the Federal Funds Rate plus 0.5%, and (3) a rate determined by Société Générale as the daily one-month LIBOR plus, in each case, (b) 4.75%, or, if we elect, at the greater of (1) 2.0% and (2) LIBOR plus, in each case, 5.75%.  At October 16, 2009, the interest rate on the term loan portion of the new credit facility was 7.75%. The term loan portion of the new credit facility is subject to amortization beginning on January 31, 2010. The first amortization installment of $1.0 million is due on January 31, 2010 and the second amortization installment of $3.0 million is due on March 31, 2010; thereafter, a quarterly amortization installment of $2.0 million is due at the end of each quarter until the term loan is repaid. It is anticipated that the term loan will be repaid on or before December 31, 2010, after which, it may not be redrawn.utilization.
 
Subject to earlier termination rights and events of default, the stated maturity date of the new credit facility is October 5, 2012.June 30, 2015. Interest is payable quarterly on reference rate advances and not less than quarterly on EurodollarLIBOR advances. We are permitted to terminate the new credit facility and are able, from time to time, to permanently reduce the lenders’ aggregate commitment under the new credit facility in compliance with certain notice and dollar increment requirements.
 
Each of our subsidiaries (other than Canadian Abraxas Petroleum Corporation) has guaranteed our obligations under the new credit facility on a senior secured basis. Obligations under the new credit facility are secured by a first priority perfected security interest, subject to certain permitted encumbrances, in all of our and our subsidiary guarantors’ material property and assets.assets, other than Raven Drilling.
 
Under the new credit facility, we are subject to customary covenants, including certain financial covenants and reporting requirements.  We are required to maintain a current ratio, as of the last day of each quarter of not less than 1.00 to 1.00 and an interest coverage ratio as of the last day of each quarter, of not less than 2.50 to 1.00.  We are also required as of the last day of each quarter to maintain a total debt to EBITDAX ratio as of the last day of each quarter of not more than 4.50 to 1.00 for the quarter ending September 30, 2009 through the quarter ending September 30, 2010, and not more than 4.00 to 1.00 thereafter.1.00. The current ratio is defined as the ratio of consolidated current assets to consolidated current liabilities.  For the purposes of this calculation, current assets include the portion of the borrowing base which is undrawn but excludes any cash deposited with or at the request of a counter-party to a hedging arrangement and any assets representing a valuation account arising from the application of SFAS 133 (which relates to derivative instrumentsASC 815 and hedging activities) and SFAS 143 (which relates to asset retirement obligations)ASC 410-20 and current liabilities exclude the current portion of long-term debt and any liabilities representing a valuation account arising from the application of SFAS 133ASC 815 and SFAS 143.ASC 410-20.  The interest coverage ratio is defined as the ratio of consolidated EBITDAX to consolidated interest expense for the four fiscal quarters ended on the calculation date after giving pro forma effect to the Merger.date. For the purposes of this calculation, EBITDAX is consolidated net income plus interest expense, oil and gas exploration expenses, income, franchise or margin taxes,

depreciation, amortization, depletion and other non-cash charges including non-cash charges resulting from the application of SFAS 123R (which relates to stock-based compensation), SFAS 133ASC 718, ASC 815 and SFAS 143ASC 410-20 plus all realized net cash proceeds arising from the settlement or monetization of any hedge contracts or upon the termination of any hedge contract minus all non-cash items of income which were included in determining consolidated net income, including all non-cash items resulting from the application of SFAS 133ASC 815 and SFAS 143.ASC 410-20. Interest expense includes total interest, letter of credit fees and other fees and expenses incurred in connection with any debt. The total debt to EBITDAX ratio is defined as the ratio of total debt to consolidated EBITDAX for the four fiscal quarters ended on the calculation date after giving pro forma effect to the Merger.date.  For the purposes of this calculation, total debt is the outstanding principal amount of debt, excluding debt associated with the office building, Raven Drilling rig loan and obligations with respect to surety bonds and hedge arrangements.
At December 31, 2012, we were in compliance with all of our debt covenants.  As of December 31, 2012, the interest coverage ratio was 7.72 to 1.00, the total debt to EBITDAX ratio was 2.97 to 1.00, our current ratio was 1.19 to 1.00 and we had liquidity of $39.1 million of which 37.0 million was availability under the credit facility.
 
The new credit facility also required that we enter into hedging arrangements for specified volumes, which equate to approximately 85% of the estimated oil and gas production from our net proved developed producing reserves through December 31, 2012 and 70% for 2013.

The rig loan agreement provided for interim borrowings payable to Raven Drilling until the final amount of the Effective Time, to file a registration statement relatingloan was determined. 
On February 14, 2012, Raven Drilling finalized the note with respect to the resalerig loan agreement.  The principal amount of the sharesnote is $7.0 million and bears interest at 4.26%, which equates to the four-year interest swap rate plus 3.50% on the date of Abraxas Petroleum common stock issuedclosing.  Interest only is due for the first 18-months of the note and thereafter, the note will amortize in full over the remaining life of the note.  Interest and principal, when required, is payable monthly.  Subject to earlier prepayment provisions and events of default, the stated maturity date of the note is February 14, 2017. As of December 31, 2012, $7.0 million was outstanding under the rig loan agreement.

RISK FACTORS
Purchasers of shares of our common stock should carefully consider the following risk factors.  These risk factors should be considered in conjunction with the other information included or incorporated by reference in this prospectus, including those in Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2008 and any forward looking statements.
Risks Related to Our Business
We incurred substantial new indebtedness in order to close the Merger, which may adversely affect our cash flow and business operations.
In connection with closing the Merger, we incurred a total of $145.0 million of indebtedness under the new credit facility which was used to refinance all of Abraxas Energy’s and Abraxas Petroleum’s outstanding indebtedness under their existing credit facilities and pay certain fees and expenses related to the Merger. Immediately prior to the Merger, Abraxas Energy had outstanding indebtedness of $135.0 million and Abraxas Petroleum had outstanding indebtedness of $5.9 million, for a total of $140.9 million, excluding the mortgage on our office building.
Our future indebtedness could have important consequences to us, including:
·our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired or such financing may not be available on favorable terms;
·covenants contained in our new credit facility and future debt arrangements will require us to meet financial tests that may affect our flexibility in planning for and reacting to changes in our business, including possible acquisition opportunities;
·we may need a substantial portion of our cash flow from operations to make principal and interest payments on our indebtedness, reducing the funds that would otherwise be available for operations and future business opportunities; and
·our level of debt will make us more vulnerable to competitive pressures or a downturn in our business or the economy generally, than our competitors with less debt.
Our ability to service our indebtedness will depend upon, among other things, our future financial and operating performance, which will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which are beyond our control. If our operating results are not sufficient to service our current or future indebtedness, we will be forced to take actions such as reducing or delaying acquisitions and/or capital expenditures, selling assets, restructuring or refinancing our indebtedness or seeking additional debt or equity capital or bankruptcy protection. We may not be able to effect any of these remedies on satisfactory terms or at all.
A breach of the terms and conditions of the new credit facility, including the inability to comply with the required financial covenants, could result in an event of default. If an event of default occurs (after any applicable notice and cure periods), the lenders would be entitled to terminate any commitment to make further extensionsadvancing line of credit under the new credit facility and to accelerate the repayment of amounts outstanding (including accrued and unpaid interest and fees).  Upon a default under the new credit facility, the lenders could also foreclose against any collateral securing such obligations, which may be all or substantially all of our assets.  If that occurred, we may not be able to continue to operate as a going concern.
We may not be able to fund the capital expenditures that will be required for us to increase reserves and production.
We must make capital expenditures to develop our existing reserves and to discover new reserves.  Historically, we have financed our capital expenditures primarily with cash flow from operations, borrowings under credit facilities, sales of producing properties, and sales of debt and equity securities and we expect to continue to do so in the future.  We cannot assure you that we will have sufficient capital resources in the future to finance all of our planned capital expenditures.

Volatility in oil and gas prices, the timing of our drilling programs and drilling results will affect our cash flow from operations.  Lower prices and/or lower production will also decrease revenues and cash flow, thus reducing the amount of financial resources available$5.4 million for the purchase and finish out of a building to meetserve as our capital requirements, including reducing the amount available to pursue our drilling opportunities.  If our cash flow from operations does not increase ascorporate headquarters. This note was refinanced in November 2008.  The note bears interest at a result of planned capital expenditures, a greater percentage of our cash flow from operations will be required for debt service and operating expenses and our planned capital expenditures would, by necessity, be decreased.
The borrowing base under our new credit facility will be determined from time to time by the lenders.  Reductions in estimates of oil and gas reserves could result in a reduction in the borrowing base, which would reduce the amount of financial resources available under the new credit facility to meet our capital requirements.  Such a reduction could be the result of lower commodity prices and/or production, inability to drill or unfavorable drilling results, changes in oil and gas reserve engineering, the lenders’ inability to agree to an adequate borrowing base or adverse changes in the lenders’ practices regarding estimation of reserves.
If cash flow from operations or our borrowing base decrease for any reason, our ability to undertake exploration and development activities could be adversely affected.  As a result, our ability to replace production may be limited.  In addition, if the borrowing base under the new credit facility is reduced, we would be required to reduce our borrowings under the new credit facility so that such borrowings do not exceed the borrowing base.  This could further reduce the cash available to us for capital spending and, if we did not have sufficient capital to reduce our borrowing level, we may be in default under the new credit facility.
We have sold producing properties to provide us with liquidity and capital resources in the past and we may do so in the future.  After any such sale, we would expect to utilize the proceeds to drill new wells on our remaining properties.  If we cannot replace the production lost from properties sold with production from the remaining properties, our cash flow from operations will likely decrease, which in turn, would decrease the amount of cash available for additional capital spending.
We may be unable to acquire or develop additional reserves, in which case our results of operations and financial condition would be adversely affected.
Our future oil and gas production, and therefore our success, is highly dependent upon our ability to find, acquire and develop additional reserves that are profitable to produce.  Thefixed rate of production from our oil5.25% and gas propertiesis payable in monthly installments of principal and our proved reserves will decline as our reserves are produced.  Unless we acquire additional properties containing proved reserves, conduct successful developmentinterest of $36,652 based on a twenty year amortization. The note matures in May 2015 at which time the outstanding balance becomes due. The note is secured by a first lien deed of trust on the property and exploration activities or, through engineering studies, identify additional behind-pipe zones or secondary recovery reserves, we cannot assure you that our exploration and development activities will result in increases in our proved reserves.  Approximately 92% of the estimated ultimate recovery of our proved developed producing reserves asimprovements. As of December 31, 2008 had been produced.  Based2012, $4.8 million was outstanding on the reserve information set forth in our reserve report as of December 31, 2008, our average annual estimated decline rate for our net proved developed producing reserves is 11% during the first five years, 8% in the next five years, and approximately 8% thereafter.  These rates of decline are estimates and actual production declines could be materially higher.  While we have had some success in finding, acquiring and developing additional reserves, we have not always been able to fully replace the production volumes lost from natural field declines and prior property sales.  For example, in 2006, we replaced only 7% of the reserves we produced.  As our proved reserves and consequently our production decline, our cash flow from operations, and the amount that we are able to borrow under our new credit facility will also decline.  In addition, approximately 46% of our total estimated proved reserves at December 31, 2008 were classified as undeveloped.  By their nature, estimates of undeveloped reserves are less certain.  Recovery of such reserves will require significant capital expenditures and successful drilling operations.  Even if we are successful in our development efforts, it could take several years for a significant portion of these undeveloped reserves to generate positive cash flow.
We may not find any commercially productive oil and gas reservoirs.
We cannot assure you that the new wells we drill will be productive or that we will recover all or any portion of our capital investment.  Drilling for oil and gas may be unprofitable.  Dry holes and wells that are productive but do not produce sufficient net revenues after drilling, operating and other costs are unprofitable.  The inherent risk of not finding commercially productive reservoirs will be compounded by the fact that 46% of our total estimated proved reserves as of December 31, 2008 were classified as undeveloped.  By their nature, estimates of undeveloped reserves are less certain.  Recovery of such reserves will require significant capital expenditures and successful drilling
6
operations.  In addition, our properties may be susceptible to drainage from production by other operations on adjacent properties.  If the volume of oil and gas we produce decreases, our cash flow from operations will decrease.
Our drilling operations may be curtailed, delayed or cancelled as a result of a variety of factors that are beyond our control or not covered by insurance.
Our drilling operations are subject to a number of risks, including:
·unexpected drilling conditions;
·facility or equipment failure or accidents;
·shortages or delays in the availability of drilling rigs, equipment and crews;
·adverse weather conditions;
·title problems;
·unusual or unexpected geological formations;
·pipeline ruptures;
·fires, blowouts and explosions; and
·uncontrollable flows of oil or gas or well fluids.
Any of these events could adversely affect our ability to conduct operations or cause substantial losses, including personal injury or loss of life, damage to or destruction of property, natural resources and equipment, pollution or other environmental, contamination, loss of wells, regulatory penalties, suspension of operations, and attorney’s fees and other expenses incurred in the prosecution or defense of litigation.
We maintain insurance against some but not all of these risks.  Additionally, we may elect not to obtain insurance if we believe that the cost of available insurance is excessive relative to the perceived risks presented.  Losses could therefore occur for uninsurable or uninsured risks or in amounts in excess of existing insurance coverage.  The occurrence of an event that is not fully covered by insurance could have a material adverse impact on our business activities, financial condition and results of operations.
Restrictive debt covenants could limit our growth and our ability to finance our operations, fund our capital needs, respond to changing conditions and engage in other business activities that may be in our best interests.
Our new credit facility contains a number of significant covenants that, among other things, limit our ability to:
·incur or guarantee additional indebtedness and issue certain types of preferred stock or redeemable stock;
·transfer or sell assets;
·create liens on assets;
·pay dividends or make other distributions on capital stock or make other restricted payments, including repurchasing, redeeming or retiring capital stock or subordinated debt or making certain investments or acquisitions;
·engage in transactions with affiliates;
·guarantee other indebtedness;
·make any change in the principal nature of our business;
·permit a change of control; or
·consolidate, merge or transfer all or substantially all of our assets.
In addition, our new credit facility requires us to maintain compliance with specified financial covenants.  Our ability to comply with these covenants may be adversely affected by events beyond our control, and we cannot assure
7
you that we can maintain compliance with these covenants.  These financial covenants could limit our ability to obtain future financings, make needed capital expenditures, withstand a future downturn in our business or the economy in general or otherwise conduct necessary or desirable business activities.
A breach of any of these covenants could result in a default under our new credit facility.  A default, if not cured or waived, could result in all of our indebtedness becoming immediately due and payable.  If that should occur, we may not be able to pay all such debt or to borrow sufficient funds to refinance it.  Even if new financing were then available, it may not be on terms that are acceptable or favorable to us.
The marketability of our production depends largely upon the availability, proximity and capacity of gas gathering systems, pipelines and processing facilities.
The marketability of our production depends in part upon processing and transportation facilities.  Transportation space on such gathering systems and pipelines is occasionally limited and at times unavailable due to repairs or improvements being made to such facilities or due to such space being utilized by other companies with priority transportation agreements.  Our access to transportation options can also be affected by U.S. Federal and state regulation of oil and gas production and transportation, general economic conditions and changes in supply and demand.  These factors and the availability of markets are beyond our control.  If market factors dramatically change, the financial impact on us could be substantial and adversely affect our ability to produce and market oil and gas.
An increase in the differential between NYMEX and the reference or regional index price used to price our oil and gas would reduce our cash flow from operations.
Our oil and gas is priced in the local markets where it is produced based on local or regional supply and demand factors.  The prices we receive for our oil and gas are typically lower than the relevant benchmark prices, such as NYMEX.  The difference between the benchmark price and the price we receive is called a differential.  Numerous factors may influence local pricing, such as refinery capacity, pipeline capacity and specifications, upsets in the midstream or downstream sectors of the industry, trade restrictions and governmental regulations.  Additionally, insufficient pipeline capacity, lack of demand in any given operating area or other factors may cause the differential to increase in a particular area compared with other producing areas.  For example, production increases from competing Canadian and Rocky Mountain producers, combined with limited refining and pipeline capacity in the Rocky Mountain area, have gradually widened differentials in this area.
During 2008, differentials averaged $7.07 per Bbl of oil and $1.30 per Mcf of gas.  Approximately 39% of our production during 2008 was from the Rocky Mountain and Mid-Continent regions.  Historically, these regions have experienced wider differentials than our Permian Basin and Gulf Coast properties.  As the percentage of our production from the Rocky Mountain and Mid-Continent regions increases, we expect that our price differentials will also increase.  Increases in the differential between the benchmark prices for oil and gas and the wellhead price we receive could significantly reduce our revenues and our cash flow from operations.
Our derivative contract activities could result in financial losses or could reduce our cash flow.
To achieve more predictable cash flow and reduce our exposure to adverse fluctuations in the prices of oil and gas and to comply with the requirements under our new credit facility, we enter into derivative contracts, which we sometimes refer to as hedging arrangements, for a significant portion of our oil and gas production that could result in both realized and unrealized derivative contract losses.  We have entered into NYMEX-based fixed price commodity swap arrangements on approximately 85% of the oil and gas production from our estimated net proved developed producing reserves through December 31, 2012 and 70% for 2013 in order to comply with the requirements of our new credit facility.   Any new hedging arrangements will be priced at then-current market prices and may be significantly lower than the commodity swaps we currently have in place.  The extent of our commodity price exposure will be related largely to the effectiveness and scope of our commodity price derivative contract activities.  For example, the prices utilized in our derivative instruments are currently NYMEX-based, which may differ significantly from the actual prices we receive for oil and gas which are based on the local markets where oil and gas are produced.  The prices that we receive for our oil and gas production are typically lower than the relevant benchmark prices that are used for calculating commodity derivative positions.  The difference between the benchmark price and the price we receive is called a differential.  As a result, our cash flow could be affected if the basis differentials widen more than we anticipate.  For more information see “—An increase in the differential between NYMEX and the reference or regional
8
index price used to price our oil and gas would reduce our cash flow from operations.” We currently do not have any basis differential hedging arrangements in place.  Our cash flow could also be affected based upon the levels of our production.  If production is higher than we estimate, we will have greater commodity price exposure than we intended.  If production is lower than the nominal amount that is subject to our hedging arrangements, we may be forced to satisfy all or a portion of our hedging arrangements without the benefit of the cash flow from our sale of the underlying physical commodity, resulting in a substantial reduction in cash flows.
If the prices at which we hedge our oil and gas production are less than current market prices, our cash flow from operations could be adversely affected.
When our derivative contract prices are higher than market prices, we will incur realized and unrealized gains on our derivative contracts and when contract prices are lower than market prices, we will incur realized and unrealized losses.  For the year ended December 31, 2008, we recognized a realized loss on oil and gas derivative contracts of $9.3 million and an unrealized gain of $40.5 million.  The realized loss resulted in a decrease in cash flow from operations.  We expect to continue to enter into similar hedging arrangements in the future to reduce our cash flow volatility.  On July 29, 2009, we entered into hedging arrangements for specified volumes, which equate to approximately 85% of the estimated oil and gas production from our proved developed producing reserves through December 31, 2012 and 70% for 2013.
We cannot assure you that the derivative contracts that we have entered into, or will enter into, will adequately protect us from financial loss in the future due to circumstances such as:
·highly volatile oil and gas prices;
·our production being less than expected; or
·a counterparty to one of our hedging transactions defaulting on its contractual obligations.
Lower oil and gas prices increase the risk of ceiling limitation write-downs.
We use the full cost method to account for our oil and gas operations.  Accordingly, we capitalize the cost to acquire, explore for and develop oil and gas properties.  Under full cost accounting rules, the net capitalized cost of oil and gas properties may not exceed a “ceiling limit” which is based upon the present value of estimated future net cash flows from proved reserves, discounted at 10%.  If net capitalized costs of oil and gas properties exceed the ceiling limit, we must charge the amount of the excess to earnings.  This is called a “ceiling limitation write-down.” This charge does not impact cash flow from operating activities, but does reduce our stockholders’ equity and earnings.  The risk that we will be required to write-down the carrying value of oil and gas properties increases when oil and gas prices are low.  In addition, write-downs may occur if we experience substantial downward adjustments to our estimated proved reserves.  An expense recorded in one period may not be reversed in a subsequent period even though oil and gas prices may have increased the ceiling applicable to the subsequent period.
At December 31, 2008, our net capitalized costs of oil and gas properties exceeded the present value of our estimated proved reserves by $116.4 million resulting in a write-down of $116.4 million.  We cannot assure you that we will not experience additional ceiling limitation write-downs in the future.
Use of our net operating loss carryforwards may be limited.
At December 31, 2008, we had, subject to the limitation discussed below, $194.4 million of net operating loss carryforwards for U.S. tax purposes.  These loss carryforwards will expire in varying amounts through 2028 if not otherwise used.
The use of our net operating loss carryforwards may be limited if an “ownership change” of over 50 percentage points occurs during any three-year period.  Based on current estimates, we believe that we have not surpassed this threshold.  With respect to any remaining net operating loss carryforwards following the Merger, it is feasible that even a modest change of ownership (including, but not limited to, a shift in common stock ownership by one reasonably large stockholder or any offering of common stock) during the three-year period following the Merger could trigger a significant limitation of the amount of such net operating loss carryforwards available to offset future taxable income.
9
Additionally, uncertainties exist as to the future utilization of the operating loss carryforwards under the criteria set forth under FASB Statement No. 109.  Therefore, we have established a valuation allowance of $66.9 million for deferred tax assets at December 31, 2006, $47.2 million at December 31, 2007 and $60.8 million at December 31, 2008.
We depend on our Chairman, President and CEO and the loss of his services could have an adverse effect on our operations.
We depend to a large extent on Robert L.G. Watson, our Chairman of the Board, President and Chief Executive Officer, for our management and business and financial contacts.  Mr. Watson may terminate his employment agreement with us at any time on 30 days notice, but, if he terminates without cause, he would not be entitled to the severance benefits provided under the terms of that agreement.  Mr. Watson is not precluded from working for, with or on behalf of a competitor upon termination of his employment with us.  If Mr. Watson were no longer able or willing to act as our Chairman, the loss of his services could have an adverse effect on our operations.note.
 
Risks Related to Our Industry
Market conditions for oil and gas, and particularly volatility of prices for oil and gas, could adversely affect our revenue, cash flows, profitability and growth.
Our revenue, cash flows, profitability and future rate of growth depend substantially upon prevailing prices for oil and gas.  Gas prices affect us more than oil prices because 65% of our production and 72% of our reserves were gas at December 31, 2008.  Prices also affect the amount of cash flow available for capital expenditures and our ability to borrow money or raise additional capital.  Lower prices may also make it uneconomical for us to increase or even continue current production levels of oil and gas.
Prices for oil and gas are subject to large fluctuations in response to relatively minor changes in the supply and demand for oil and gas, market uncertainty and a variety of other factors beyond our control, including:
·changes in foreign and domestic supply and demand for oil and gas;
·political stability and economic conditions in oil producing countries, particularly in the Middle East;
·general economic conditions;
·domestic and foreign governmental regulation; and
·the price and availability of alternative fuel sources.
The current global recession has had a significant impact on commodity prices and our operations.  If commodity prices remain depressed, our revenues, profitability and cash flow from operations may decrease which could cause us to alter our business plans, including reducing our drilling activities.
Estimates of proved reserves and future net revenue are inherently imprecise.
The process of estimating oil and gas reserves is complex involving decisions and assumptions in evaluating the available geological, geophysical, engineering and economic data.  Accordingly, these estimates are imprecise.  Actual future production, oil and gas prices, revenues, taxes, capital expenditures, operating expenses and quantities of recoverable oil and gas reserves most likely will vary from those estimated.  Any significant variance could materially affect the estimated quantities and present value of our reserves set forth or incorporated by reference in this prospectus.  In addition, we may adjust estimates of proved reserves to reflect production history, results of exploration and development, prevailing oil and gas prices and other factors, many of which are beyond our control.
The estimates of our reserves are based upon various assumptions about future production levels, prices and costs that may not prove to be correct over time.  In particular, estimates of oil and gas reserves, future net revenue from proved reserves and the PV-10 thereof for our oil and gas properties are based on the assumption that future oil and gas prices remain the same as oil and gas prices at December 31, 2008.  The sales prices as of such date used for purposes of such estimates were $4.77 per Mcf of gas and $41.84 per Bbl of oil.  This compares with $6.33 per Mcf of gas and $87.30 per Bbl of oil as of December 31, 2007.  These estimates also assume that we will make future capital
10
expenditures of approximately $134.1 million in the aggregate primarily from 2009 through 2014, which are necessary to develop and realize the value of proved undeveloped reserves on our properties.  In addition, approximately 46% of our total estimated proved reserves as of December 31, 2008 were classified as undeveloped.  By their nature, estimates of undeveloped reserves are less certain than proved developed reserves.  Any significant variance in actual results from these assumptions could also materially affect the estimated quantity and value of our reserves set forth or incorporated by reference in this prospectus.
The present value of future net cash flows from our proved reserves is not necessarily the same as the current market value of our estimated reserves.  Any material inaccuracies in our reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves, which could adversely affect our business, results of operations and financial condition.
As required by SEC regulations, we base the estimated discounted future net cash flows from our proved reserves on prices and costs in effect on the day of the estimate.  However, actual future net cash flows from our properties will be affected by factors such as:
·supply of and demand for oil and gas;
·actual prices we receive for oil and gas;
·our actual operating costs;
·the amount and timing of our capital expenditures;
·the amount and timing of actual production; and
·changes in governmental regulations or taxation.
The timing of both our production and our incurrence of expenses in connection with the development and production of our properties will affect the timing of actual future net cash flows from proved reserves, and thus their actual present value.  In addition, the 10% discount factor we use when calculating discounted future net cash flow, which is required by the SEC, may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and gas industry in general.  Any material inaccuracies in our reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves, which could adversely affect our business, results of operations and financial condition.
Our operations are subject to the numerous risks of oil and gas drilling and production activities.
Our oil and gas drilling and production activities are subject to numerous risks, many of which are beyond our control.  These risks include the risk of fire, explosions, blow-outs, pipe failure, abnormally pressured formations and environmental hazards.  Environmental hazards include oil spills, gas leaks, ruptures and discharges of toxic gases.  In addition, title problems, weather conditions and mechanical difficulties or shortages or delays in delivery of drilling rigs and other equipment could negatively affect our operations.  If any of these or other similar industry operating risks occur, we could have substantial losses.  Substantial losses also may result from injury or loss of life, severe damage to or destruction of property, clean-up responsibilities, regulatory investigation and penalties and suspension of operations.  In accordance with industry practice, we maintain insurance against some, but not all, of the risks described above.  We cannot assure you that our insurance will be adequate to cover losses or liabilities.  Also, we cannot predict the continued availability of insurance at premium levels that justify its purchase.
We operate in a highly competitive industry which may adversely affect our operations.
We operate in a highly competitive environment.  The principal resources necessary for the exploration and production of oil and gas are leasehold prospects under which oil and gas reserves may be discovered, drilling rigs and related equipment to explore for such reserves and knowledgeable personnel to conduct all phases of oil and gas operations.  We must compete for such resources with both major oil and gas companies and independent operators.  Many of these competitors have financial and other resources substantially greater than ours.  Although we believe our current operating and financial resources are adequate to preclude any significant disruption of our operations in the immediate future, we cannot assure you that such resources will be available to us.
11
The unavailability or high cost of drilling rigs, equipment, supplies, insurance, personnel and oil field services could adversely affect our ability to execute our exploration and development plans on a timely basis and within our budget.
Our industry is cyclical and, from time to time, there could be a shortage of drilling rigs, equipment, supplies, insurance or qualified personnel.  During these periods, the costs and delivery times of rigs, equipment and supplies are substantially greater.  In addition, the demand for, and wages of, qualified drilling rig crews rise as the number of active rigs in service increases.  When oil and gas prices are high, the demand for oilfield services rises and the cost of these services increases.
Our oil and gas operations are subject to various Federal, state and local regulations that materially affect our operations.
Matters regulated include permits for drilling operations, drilling and abandonment bonds, reports concerning operations, the spacing of wells and unitization and pooling of properties and taxation.  At various times, regulatory agencies have imposed price controls and limitations on production.  In order to conserve supplies of oil and gas, these agencies have restricted the rates of flow from oil and gas wells below actual production capacity.  Federal, state and local laws regulate production, handling, storage, transportation and disposal of oil and gas, by-products from oil and gas and other substances and materials produced or used in connection with oil and gas operations.  To date, our expenditures related to complying with these laws and for remediation of existing environmental contamination have not been significant.  We believe that we are in substantial compliance with all applicable laws and regulations.  However, the requirements of such laws and regulations are frequently changed.  We cannot predict the ultimate cost of compliance with these requirements or their effect on our operations.
Risks Related to Our Common Stock
Future issuance of additional shares of common stock could cause dilution of ownership interests and adversely affect the stock price.
We are currently authorized to issue 200,000,000 shares of common stock with such rights as determined by our board of directors.  We may in the future issue previously authorized and unissued securities, resulting in the dilution of the ownership interests of current stockholders.  The potential issuance of any such additional shares of common stock may create downward pressure on the trading price of our common stock.  We may also issue additional shares of common stock or other securities that are convertible into or exercisable for common stock for capital raising or other business purposes.  Future sales of substantial amounts of common stock, or the perception that sales could occur, could have a material adverse effect on the price of our common stock.
We do not pay dividends on common stock.
We have never paid a cash dividend on our common stock and the terms of the new credit facility prohibit us from paying dividends on our common stock.
Shares eligible for future sale may depress our stock price.
At October 16, 2009, we had 76,083,117 shares of common stock outstanding of which 5,333,269 shares were held by affiliates and, in addition, 4,235,144 shares of common stock were subject to outstanding options granted under stock option plans (of which 2,102,874 shares were vested at October 16, 2009).
All of the shares of common stock held by affiliates are restricted or control securities under Rule 144 promulgated under the Securities Act of 1933, as amended.  The shares of common stock issuable upon exercise of stock options have been registered under the Securities Act.  Sales of shares of common stock under Rule 144 or another exemption under the Securities Act or pursuant to a registration statement could have a material adverse effect on the price of our common stock and could impair our ability to raise additional capital through the sale of equity securities.
12
The price of our common stock has been volatile and could continue to fluctuate substantially.
Our common stock is traded on The NASDAQ Stock Market.  The market price of our common stock has been volatile and could fluctuate substantially based on a variety of factors, including the following:
·fluctuations in commodity prices;
·variations in results of operations;
·legislative or regulatory changes;
·general trends in the industry;
·market conditions; and
·analysts’ estimates and other events in the oil and gas oil industry.
We may issue shares of preferred stock with greater rights than our common stock.
Subject to the rules of The NASDAQ Stock Market, our articles of incorporation authorize our board of directors to issue one or more series of preferred stock and set the terms of the preferred stock without seeking any further approval from holders of our common stock.  Any preferred stock that is issued may rank ahead of our common stock in terms of dividends, priority and liquidation premiums and may have greater voting rights than our common stock.
Anti-takeover provisions could make a third party acquisition of Abraxas difficult.
Our articles of incorporation and bylaws provide for a classified board of directors, with each member serving a three-year term, and eliminate the ability of stockholders to call special meetings or take action by written consent.  Each of the provisions in the articles of incorporation and bylaws could make it more difficult for a third party to acquire Abraxas without the approval of its board.  In addition, the Nevada corporate statute also contains certain provisions that could make an acquisition by a third party more difficult.
An active market may not continue for our common stock and we could face de-listing if our stock price declines.
Our common stock is quoted on The NASDAQ Stock Market.  While there are currently three market makers in our common stock, these market makers are not obligated to continue to make a market in our common stock.  In this event, the liquidity of our common stock could be adversely impacted and a stockholder could have difficulty obtaining accurate stock quotes.  If our stock price declines and remains below $1.00 per share for an extended period of time, we could be de-listed from The NASDAQ Stock Market as the minimum threshold for a continued listing is $1.00 per share.

Option Plans
 
The Abraxas Petroleum Corporation 2005 Employee Long-Term Incentive Plan, or LTIP, authorizes us to grant incentive stock options, non-qualified stock options and shares of restricted stock to our executive officers, as well as to all of our employees.  Option grants generally have a term of 10 years and vest in equal increments over 4 years.  Restricted stock grants vest in accordance with each individual grant agreement.  Vesting is accelerated in certain events such as a change of control.  A total of 5,200,0009,200,000 shares of Abraxas common stock are currently reserved under the LTIP, subject to adjustment following certain events, such as stock splits.
 
Pursuant to Abraxas Petroleum’s 2005 Director Plan, we also grant non-qualified stock options and restricted stock to non-employee directors.  This plan is administered by our compensation committee and provides that each year, at the first regular meeting of the board of directors immediately following our annual stockholder’s meeting, each non-employee director shall be granted or issued awards of 10,00012,000 shares of our common stock, for participation in board and committee meetings during the previous calendar year.  We also pay each director’s annual retainer fee, which is currently $12,000, in shares of restricted stock pursuant to the 2005 Director Plan.  The number of shares issued to each non-employee director is calculated each quarter by dividing one-quarter of the then-established annual retainer fee by the closing price of our common stock on the date of each quarterly board meeting.  Fractional shares are not issued; therefore, any shortfall of the then-established annual retainer fee will be paid in cash after the last quarterly board meeting of each year.  Any non-employee director who leaves the board during the calendar year is not eligible for any restricted stock awards after leaving the board.
 
The compensation committee also administers our 1993 Key Contributor Stock Option Plan, 1994 Long Term Incentive Plan, Directors Restricted Share Plan and Director Stock Option Plan, each of which is now expired, but under which we previously granted restricted stock, incentive stock options and non-qualified stock options as permitted by such plans.

Rights Plan

On March 16, 2010, we adopted a Tax Benefits Preservation Plan (the “Tax Benefits Preservation Plan”) and declared a dividend of one preferred share purchase right for each outstanding share of our common stock. The terms of the preferred stock purchase  rights and the Tax Benefits Preservation Plan are set forth in a Rights Agreement, by and between Abraxas and American Stock Transfer & Trust Company, LLC, as Rights Agent, dated as of March 16, 2010.

13
This summary of the preferred share purchase rights provides only a general description of the Tax Benefits Preservation Plan, and thus, should be read together with the entire Tax Benefits Preservation Plan, which has been incorporated by reference herein.

We adopted the Tax Benefits Preservation Plan in an effort to protect stockholder value by attempting to protect against a possible limitation on our ability to use our net operating loss carryforwards (the “NOLs”) to reduce potential future federal income tax obligations. We have experienced and continue to experience substantial operating losses, and under the Internal Revenue Code and rules promulgated by the Internal Revenue Service, we may “carry forward” these losses in certain circumstances to offset any current and future earnings and thus reduce our federal income tax liability, subject to certain requirements and restrictions. To the extent that the NOLs do not otherwise become limited, we believe that we will be able to carry forward a significant amount of NOLs, and therefore these NOLs could be a substantial asset to us. However, if we experience an “Ownership Change,” as defined in Section 382 of the Internal Revenue Code, our ability to use the NOLs will be substantially limited, and the timing of the usage of the NOLs could be substantially delayed, which could therefore significantly impair the value of that asset.

The Tax Benefits Preservation Plan is intended to act as a deterrent to any person or group acquiring 4.9% or more of our outstanding common stock (an “Acquiring Person”) without our approval. Stockholders who owned 4.9% or more of our outstanding common stock as of the close of business on March 16, 2010 will not trigger the Tax Benefits Preservation Plan so long as they do not (i) acquire any additional shares of common stock or (ii) fall under 4.9% ownership of common stock and then re−acquire 4.9% or more of the common stock. The Tax Benefits Preservation Plan does not exempt any future acquisitions of common stock by such persons. Any rights held by an Acquiring Person are null and void and may not be exercised. We may, in our sole discretion, exempt any person or group from being deemed an Acquiring Person for purposes of the Tax Benefits Preservation Plan.

The Preferred Stock Purchase Rights. We authorized the issuance of one preferred stock purchase right per each outstanding share of our common stock payable to our stockholders of record as of March 16, 2010. Subject to the terms, provisions and conditions of the Tax Benefits Preservation Plan, if the preferred stock purchase rights become exercisable, each preferred stock purchase right would initially represent the right to purchase from us one one−thousandth of a share of our Series 2010 Junior Participating Preferred Stock (“Series 2010 Preferred Stock”) for a purchase price of $7.00 (the “Purchase Price”) . If issued, each fractional share of Series 2010 Junior Preferred Stock would give the stockholder approximately the same dividend, voting and liquidation rights as does one share of our common stock. However, prior to exercise, a preferred stock purchase right does not give its holder any rights as a stockholder  including, without limitation any dividend, voting or liquidation rights.

Series 2010 Preferred Stock Provisions. Each one one-thousandth of a share of Series 2010 Preferred Stock, if issued: (1) will not be redeemable; (2) will entitle holders to quarterly dividend payments of $0.01 per one one-thousandth of a share of Series 2010 Preferred Stock, or an amount equal to the dividend paid on one share of common stock, whichever is greater, if, as and when declared by our board of directors out of funds legally available therefor; (3) will entitle holders upon liquidation either to receive $1.00 per one one-thousandth of a share of Series 2010 Preferred Stock or an amount equal to the payment made on one share of common stock, whichever is greater; (4) will have the same voting power as one share of common stock; and (5) if shares of our common stock are exchanged via merger, consolidation, or a similar transaction, will entitle holders to a per share payment equal to the payment made on one share of common stock. The value of one one-thousandth interest in a Preferred Share should approximate the value of one share of common stock.

Exercisability. The preferred stock purchase rights will not be exercisable until the earlier of (i) 10 business days after a public announcement by us that a person or group has become an Acquiring Person and (ii) 10 business days after the commencement of a tender or exchange offer by a person or group for 4.9% of the common stock.

14
We refer to the date that the preferred stock purchase rights become exercisable as the “Distribution Date.” Until the Distribution Date, our common stock certificates will evidence the preferred stock purchase rights and will contain a notation to that effect. Any transfer of shares of common stock prior to the Distribution Date will constitute a transfer of the associated  preferred stock purchase rights. After the Distribution Date, the preferred stock purchase rights may be transferred other than in connection with the transfer of the underlying shares of common stock.

After the Distribution Date, each holder of a preferred stock purchase right, other than  preferred stock purchase rights beneficially owned by the Acquiring Person (which will thereupon become void), will thereafter have the right to receive upon exercise of a  preferred stock purchase right and payment of the Purchase Price, that number of shares of common stock having a market value at the time of exercise of two times the Purchase Price.

Exchange. After the Distribution Date, we may exchange the  preferred stock purchase rights (other than  preferred stock purchase rights owned by an Acquiring Person, which will have become void), in whole or in part, at an exchange ratio of one share of common stock, or a fractional share of Series 2010 Preferred Stock (or of a share of a similar class or series of our preferred stock having similar rights, preferences and privileges) of equivalent value, per  preferred stock purchase right (subject to adjustment).

Expiration. The  preferred stock purchase rights and the Tax Benefits Preservation Plan will expire on the earliest of (i) March 16, 2015, (ii) the time at which the  preferred stock purchase rights are redeemed pursuant to the Rights Agreement, (iii) the time at which the  preferred stock purchase rights are exchanged pursuant to the Rights Agreement, (iv) the repeal of Section 382 of the Code or any successor statute if we determine that the Rights Agreement is no longer necessary for the preservation of NOLs and (v) the beginning of a taxable year in which we determine that no NOLs may be carried forward.

Redemption. At any time prior to the time an Acquiring Person becomes such, we may redeem the  preferred stock purchase rights in whole, but not in part, at a price of $0.01 per  preferred stock purchase right (the “Redemption Price”). The redemption of the  preferred stock purchase rights may be made effective at such time, on such basis and with such conditions as we in our sole discretion may establish. Immediately upon any redemption of the  preferred stock purchase rights, the right to exercise the  preferred stock purchase rights will terminate and the only right of the holders of  preferred stock purchase rights will be to receive the Redemption Price.

Anti−Dilution Provisions. We may adjust the purchase price of the shares of Series 2010 Preferred Stock, the number of shares Series 2010 Preferred Stock issuable and the number of outstanding  preferred stock purchase rights to prevent dilution that may occur as a result of certain events, including among others, a stock dividend, a stock split or a reclassification of the shares of Series 2010 Preferred Stock or our common stock. No adjustments to the purchase price of less than 1% will be made.

Amendments. Before the Distribution Date, we may amend or supplement the Tax Benefits Preservation Plan without the consent of the holders of the  preferred stock purchase rights. After the Distribution Date, we may amend or supplement the Tax Benefits Preservation Plan only to cure an ambiguity, to alter time period provisions, to correct inconsistent provisions, or to make any additional changes to the Tax Benefits Preservation Plan, but only to the extent that those changes do not impair or adversely affect any holder of preferred stock purchase rights.

The preferred stock purchase rights have certain anti-takeover effects. The  preferred stock purchase rights will cause substantial dilution to a person or group who attempts to acquire us on terms not approved by us. The  preferred stock purchase rights should not interfere with any merger or other business combination approved by us since we may redeem the preferred stock purchase rights at $0.01 per  preferred stock purchase right at any time until the date on which a person or group has become an Acquiring Person.
15
Anti-takeover Effects of Certain Provisions of the Articles of Incorporation and Bylaws
 
Our articles of incorporation and bylaws provide for the board of directors to be divided into three classes of directors serving staggered three-year terms.  As a result, approximately one-third of the board of directors will be elected each year.  The articles of incorporation and bylaws provide that the board of directors will consist of not less than three or more than twelve members, with the exact number to be determined from time to time by the affirmative vote of a majority of directors then in office.  The board of directors, and not the stockholders, has the authority to determine the number of directors.  This provision could prevent any stockholder from obtaining majority representation on the Abraxas board by enlarging the board of directors and by filling the new directorships with the stockholder’s own nominees.  In addition, directors may be removed by the stockholders only for cause.
 
Our articles of incorporation and bylaws provide that special meetings of our stockholders may be called only by the Chairman of the board, the President or a majority of the members of the board of directors.  This provision may make it more difficult for stockholders to take actions opposed by the board of directors.
 
Our articles of incorporation and bylaws provide that any action required to be taken or which may be taken by holders of our common stock must be effected at a duly called annual or special meeting of such holders, and may not be taken by any written consent of such stockholders.  These provisions may have the effect of delaying consideration of a stockholder proposal until the next annual meeting unless a special meeting is called by the persons set forth above.  The provisions of the articles of incorporation and bylaws prohibiting stockholder action by written consent could prevent the holders of a majority of the voting power of Abraxas from using the written consent procedure to take stockholder action and taking action by consent without giving all of our stockholders entitled to vote on a proposed action the opportunity to participate in determining such proposed action.
 
Anti-Takeover Statutes
 
Chapter 78 of the Nevada Revised Statutes, which we refer to as the Nevada GCL,Law, contains two provisions, described below as “Combination Provisions” and the “Control Share Act,” that may make the unsolicited or hostile attempts to acquire control of a corporation through certain types of transactions more difficult.
 
Restrictions on Certain Combinations between Nevada Resident Corporations and Interested Stockholders
 
The Combination Provisions of Sections 78.411 through 78.444, inclusive, of the Nevada GCL includes certainLaw include provisions (the “Combination Provisions”) prohibiting certain “combinations”business combinations (generally defined to include certain mergers, disposition of assets transactions, and share issuance or transfer transactions) between a resident domestic corporation and an “interested stockholder”interested stockholder (generally defined to be the beneficial owner of 10% or more of the voting power of the outstanding shares of the corporation), except those combinations which are approved byresident domestic corporation or certain of its affiliates) with certain statutory exceptions under the board of directors before the interested stockholder first obtained a 10% interest in the corporation’s stock.  There are additional exceptions to the prohibition, which apply to combinations if they occur more than three years after the interested stockholder’s date of acquiring shares.Nevada law.  The Combination Provisions apply unless the corporation elects against their application in its original articles of incorporation or an
16
amendment thereto or timely elected against their application in its bylaws no later than October 31, 1991.  Our articles of incorporation and bylaws do not currently contain a provision rendering the Combination Provisions inapplicable.
 
Nevada Control Share Act
 
Nevada Revised Statutes 78.378 through 78.3793, inclusive, which we refer to as the Control Share Act, imposes procedural hurdles on and curtails greenmail practices of corporate raiders.  The Control Share Act temporarily disenfranchises the voting power of “control shares”control shares of a person or group (“Acquiring Person”acquiring person”) purchasing a “controlling interest”controlling interest in an “issuing corporation” (as defined in the Nevada GCL)issuing corporation not opting out of the Control Share Act.  In this regard, the Control Share Act will apply to an “issuing corporation” unless, before an acquisition is made, the articles of incorporation or bylaws in effect on the tenth day following the acquisition of a controlling interest provide that it is inapplicable.  Our articles of incorporation and bylaws do not currently contain a provision rendering the Control Share Act inapplicable.
 
16
Under the Control Share Act, an “issuing corporation”issuing corporation is a corporation organized in Nevada which has 200 or more stockholders, at least 100 of whom are stockholders of record and residents ofhave addresses in Nevada, and which does business in Nevada directly or through an affiliated company.  Our statusarticles of incorporation and bylaws at the time of the occurrence of a transaction governed by the Control Share Act (assuming that our articles of incorporation or bylaws have not theretofore been amended to include an opting out provision) would determine whether the Control Share Act is applicable.
 
The Control Share Act requires an Acquiring Personacquiring person to take certain procedural steps before such Acquiring Personacquiring person can obtain the full voting power of the control shares.  “Control shares”Control shares are the shares of a corporation (1) acquired or offered to be acquired which will enable the Acquiring Personacquiring person to own a “controllingcontrolling interest,” and (2) acquired within 90 days immediately preceding that date.  A “controlling interest”controlling interest is defined as the ownership of outstanding voting shares which would enable the Acquiring Personacquiring person to exercise certain graduatedthreshold amounts (beginning with one-fifth) of all voting power of the corporation.  The Acquiring Personacquiring person may not vote any control shares without first obtaining approval from the stockholders not characterized as “interested stockholders” (as defined below).
 
To obtain voting rights in control shares, the Acquiring Person must fileacquiring person may deliver a statement at the registered office of the issuer (“Offeror’s Statement”) setting forth certain information about the acquisition or intended acquisition of stock.  The Offeror’s Statement may also request a special meeting of stockholders to determine the voting rights to be accorded to the Acquiring Person.  Aacquiring person.  If the acquiring person undertakes to pay the expense of a special meeting, then a special stockholders’ meeting must thenshall be held at the Acquiring Person’sacquiring person’s expense within 30 to 50 days after the Offeror’s Statement is filed.  If a special meeting is not requested by the Acquiring Person,acquiring person, the matter will be addressed at the next regular or special meeting of stockholders.
 
At the special or annual meeting at which the issue of voting rights of control shares will be addressed, “interested stockholders”interested stockholders may not vote on the question of granting voting rights to control the corporation or its parent unless the articles of incorporation of the issuing corporation provide otherwise.  Our articles of incorporation do not currently contain a provision allowing for such voting power.
 
If full voting power is granted to the Acquiring Personacquiring person by the disinterested stockholders, and the Acquiring Personacquiring person has acquired control shares with a majority or more of the voting power, then (unless otherwise provided in the articles of incorporation or bylaws in effect on the tenth day following the acquisition of a controlling interest) all stockholders of record, other than the Acquiring Person,acquiring person, who have not voted in favor of authorizing voting rights for the control shares, must be sent a “dissenter’s notice” advising them of the fact and of their right to receive “fair value”fair value for their shares.shares pursuant to Sections 92A.300 through 92A.500 of the Nevada Law.  Our articles of incorporation and bylaws do not provide otherwise.  By the date set in the dissenter’s notice, which may not be less than 30 or more than 60 days after the dissenter’s notice is delivered, any such stockholder may demand to receive from the corporation the “fair value” for all or part of his shares.  “Fair value” is defined in the Control Share Act as “not less than the highest price per share paid by the Acquiring Person in an acquisition.”
 
The Control Share Act permits a corporation to redeem the control shares in the following two instances, if so provided in the articles of incorporation or bylaws of the corporation in effect on the tenth day following the acquisition of a controlling interest: (1) if the Acquiring Personacquiring person fails to deliver the Offeror’s Statement to the corporation within 10 days after the Acquiring Person’sacquiring person’s acquisition of the control shares; or (2) an Offeror’s Statement is delivered, but the control shares are not accorded full voting rights by the stockholders.  Our articles of incorporation and bylaws do not address this matter.

Dividends and Other Distributions
The depositary will distribute all cash dividends or other cash distributions received in respect of the preferred stock to the record holders of depositary shares relating to that preferred stock in proportion to the number of depositary shares owned by those holders.
If there is a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary shares that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the applicable holders.
Redemption of Depositary Shares
If a series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of that series of preferred stock held by the depositary. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to that series of the preferred stock. Whenever we redeem shares of preferred stock that are held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the shares of preferred stock so redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as determined by the depositary.
After the date fixed for redemption, the depositary shares called for redemption will no longer be outstanding, and all rights of the holders of those depositary shares will cease, except the right to receive any money, securities, or other property upon surrender to the depositary of the depositary receipts evidencing those depositary shares.
Voting the Preferred Stock
Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary shares underlying that preferred stock. Each record holder of those depositary shares on the record date (which will be the same date as the record date for the preferred stock) will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of the preferred stock underlying that holder’s depositary shares. The depositary will try, as far as practicable, to vote the number of shares of preferred stock underlying those depositary shares in accordance with such instructions, and we will agree to take all action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote the shares of preferred stock to the extent it does not receive specific instructions from the holders of depositary shares underlying the preferred stock.

·  any initial public offering price;
·  any discounts or concessions allowed or reallowed or paid to dealers; and
·  any commissions paid to agents.
Sales Through Underwriters or Dealers
If we use underwriters in the sale, the underwriters will acquire the securities for their own accounts.  The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale.  Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters.  Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them.  The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.
During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market.  These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering.  The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions.  These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market.  If commenced, the underwriters may discontinue these activities at any time.
22
If we use dealers in the sale of securities, we will sell the securities to them as principals.  They may then resell those securities to the public at varying prices determined by the dealers at the time of resale.  Transactions through brokers or dealers may include block trades in which brokers or dealers will attempt to sell securities as agent but may position and resell as principal to facilitate the transaction or in crosses, in which the same broker or dealer acts as agent on both sides of the trade. Any such dealer may be deemed an underwriter, as such term is defined in the Securities Act of 1933, as amended (the “Securities Act”), of the securities offered and sold. The prospectus supplement will include the names of the dealers and the terms of the transaction.
Direct Sales and Sales Through Agents
We may sell the securities directly.  In this case, no underwriters or agents would be involved.  We may sell securities upon the exercise of subscription rights that we may issue to our security holders which may or may not be transferable.  In any distribution of subscription rights to our stockholders, if all of the underlying securities are not subscribed for, we may sell the unsubscribed securities directly to third parties or we may engage underwriters, dealers or agents, including standby underwriters, to sell the unsubscribed securities.  We may also sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities.  In addition, sales not covered by this prospectus has been sold or otherwise transferredmay also be made pursuant to a registration statementRule 144 or otherwise.another applicable exemption under the Securities Act.
 
LEGAL MATTERSWe may sell the securities through agents we designate from time to time.  Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.
“At the Market” Offering
We may from time to time engage a firm to act as our agent for one or more offerings of our securities. We sometimes refer to this agent as our “offering agent.” If we reach an agreement with an offering agent with respect to a specific offering, including the number of securities and any minimum price below which sales may not be made, then the offering agent will try to sell such securities on the agreed terms. The offering agent could make sales in privately negotiated transactions or any other method permitted by law, including sales deemed to be an “at the market” offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on the New York Stock Exchange, or sales made to or through a market maker other than on an exchange. The offering agent will be deemed to be an “underwriter” within the meaning of the Securities Act with respect to any sales effected through an “at the market” offering.
Electronic Auctions
We may also make sales through the Internet or through other electronic means. Since we may from time to time elect to offer securities directly to the public, with or without the involvement of agents, underwriters or dealers, utilizing the Internet (sometimes referred to as the “world wide web”) or other forms of electronic bidding or ordering systems for the pricing and allocation of such securities, you will want to pay particular attention to the description of that system we will provide in a prospectus supplement.
Such electronic system may allow bidders to directly participate, through electronic access to an auction site, by submitting conditional offers to buy that are subject to acceptance by us, and which may directly affect the price or other terms and conditions at which such securities are sold. These bidding or ordering systems may present to each bidder, on a so-called “real-time” basis, relevant information to assist in making a bid, such as the clearing spread at which the offering would be sold, based on the bids submitted, and whether a bidder’s individual bids would be accepted, prorated or rejected. For example, in the case of a debt security, the clearing spread could be indicated as a number
23
of “basis points” above an index treasury note. Of course, many pricing methods can and may also be used. Upon completion of such an electronic auction process, securities will be allocated based on prices bid, terms of bid or other factors. The final offering price at which securities would be sold and the allocation of securities among bidders would be based in whole or in part on the results of the Internet or other electronic bidding process or auction.
Market Making, Stabilization and Other Transactions
Each series of securities offered by this prospectus may be a new issue of securities with no established trading market.  Any underwriters to whom securities offered by this prospectus are sold by us for public offering and sale may make a market in the securities offered by this prospectus, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice.  No assurance can be given as to the liquidity of the trading market for any securities offered by this prospectus.
Representatives of the underwriters through whom our securities are sold for public offering and sale may engage in over-allotment, stabilizing transactions, syndicate short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.  Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position.  Stabilizing transactions permit bids to purchase the offered securities so long as the stabilizing bids do not exceed a specified maximum.
Syndicate covering transactions involve purchases of the offered securities in the open market after the distribution has been completed in order to cover syndicate short positions.  Penalty bids permit the representative of the underwriters to reclaim a selling concession from a syndicate member when the offered securities originally sold by such syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions.  Such stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the offered securities to be higher than it would otherwise be in the absence of such transactions.  These transactions may be effected on a national securities exchange and, if commenced, may be discontinued at any time.
General Information
Underwriters, dealers and agents that participate in the distribution of our securities may be underwriters as defined in the Securities Act, and any discounts or commissions they receive and any profit they make on the resale of the offered securities may be treated as underwriting discounts and commissions under the Securities Act.  Any underwriters or agents will be identified and their compensation described in a prospectus supplement.  We may indemnify underwriters, dealers and agents against certain civil liabilities, including liabilities under the Securities Act, or make contributions to payments they may be required to make relating to those liabilities.  Our underwriters, dealers, and agents, or their affiliates, may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.
Agents, underwriters and dealers may engage in transactions with, or perform services for, us and our respective subsidiaries in the ordinary course of business.
 
The validityplace and time of delivery for the issuance ofsecurities will be set forth in the common stock covered byaccompanying prospectus supplement for such securities.

Item 15.  Indemnification of Directors Andand Officers
 
Chapter 78Subsection 7 of Section 78.138 of the Nevada Revised Statutes (the “Nevada Statute”Law”) containsprovides that, subject to certain very limited statutory exceptions, a director or officer is not individually liable to the corporation or its stockholders or creditors for any damages as a result of any act or failure to act in his or her capacity as a director or officer, unless it is proven that the act or failure to act constituted a breach of his or her fiduciary duties as a director or officer and such breach of those duties involved intentional misconduct, fraud or a knowing violation of law. The statutory standard of liability established by Section 78.138 controls unless there is a provision in the corporation’s articles of incorporation or an amendment to Abraxas’ Articles of Incorporation which were to provide for greater individual liability.
Subsection 1 of Section 78.7502 of the Nevada Law empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (any such person, a “Covered Person”), against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the Covered Person in connection with such action, suit or proceeding if the Covered Person is not liable pursuant to Section 78.138 of the Nevada Law or the Covered Person acted in good faith and in a manner the Covered Person reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceedings, had no reasonable cause to believe the conduct was unlawful.
Subsection 2 of Section 78.7502 of the Nevada Law empowers a corporation to indemnify any Covered Person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in the capacity of a Covered Person against expenses, including amounts paid in settlement and attorneys’ fees actually and reasonably incurred by the Covered Person in connection with the defense or settlement of such action or suit, if the Covered Person is not liable pursuant to Section 78.138 of the Nevada Law or the Covered Person acted in good faith
II-1
and in a manner the Covered Person reasonably believed to be in or not opposed to the best interests of the corporation. However, no indemnification may be made in respect of any claim, issue or matter as to which the Covered Person shall have been adjudged by a court of competent jurisdiction (after exhaustion of all appeals) to be liable to the corporation or for amounts paid in settlement to the corporation unless and only to the extent that the court in which such action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances the Covered Person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.
Section 78.7502 of the Nevada Law further provides that to the extent a Covered Person has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in Subsection 1 or 2, as described above, or in the defense of any claim, issue or matter therein, the corporation shall indemnify the Covered Person against expenses (including attorneys’ fees) actually and reasonably incurred by the Covered Person in connection with the defense.
Subsection 1 of Section 78.751 of the Nevada Law provides that any discretionary indemnification pursuant to Section 78.7502 of the Nevada Law, unless ordered by a court or advanced pursuant to Subsection 2 of Section 78.751, may be made by a corporation only as authorized in the specific case upon a determination that indemnification of the Covered Person is proper in the circumstances. Such determination must be made (a) by the stockholders, (b) by the board of directors of the corporation by majority vote of a quorum consisting of directors who were not parties to the action, suit or proceeding, (c) if a majority vote of a quorum of such non-party directors so orders, by independent legal counsel in a written opinion, or (d) by independent legal counsel in a written opinion if a quorum of such non-party directors cannot be obtained.
Subsection 2 of Section 78.751 of the Nevada Law provides that a corporation’s articles of incorporation or bylaws or an agreement made by the corporation may require the corporation to pay as incurred and in advance of the final disposition of an action, suit or proceeding, the expenses of officers and directors in defending such action, suit or proceeding upon receipt by the corporation of an undertaking by or on behalf of the officer or director to repay the amount if it is ultimately determined by a court of competent jurisdiction that he or she is not entitled to be indemnified by the corporation. Subsection 2 of Section 78.751 further provides that its provisions do not affect any rights to advancement of expenses to which corporate personnel other than officers and directors may be entitled under contract or otherwise by law.
Subsection 3 of Section 78.751 of the Nevada Law provides that eliminateindemnification pursuant to Section 78.7502 of the Nevada Law and advancement of expenses authorized in or ordered by a court pursuant to Section 78.751 does not exclude any other rights to which the Covered Person may be entitled under the articles of incorporation or any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in his or her official capacity or in another capacity while holding his or her office. However, indemnification, unless ordered by a court pursuant to Section 78.7502 or for the advancement of expenses under Subsection 2 of Section 78.751 of the Nevada Law, may not be made to or on behalf of any director or officer of the corporation if a final adjudication establishes that his or her acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and were material to the cause of action. Additionally, the scope of such indemnification and advancement of expenses shall continue for a Covered Person who has ceased to be a director, officer, employee or agent of the corporation, and shall inure to the benefit of his or her heirs, executors and administrators.
Section 78.752 of the Nevada Law empowers a corporation to purchase and maintain insurance or make other financial arrangements on behalf of a Covered Person for any liability asserted against such person and liabilities and expenses incurred by such person in his or her capacity as a Covered Person or arising out of such person’s status as a Covered Person whether or not the corporation has the authority to indemnify such person against such liability and expenses.
The Amended and Restated Bylaws of Abraxas provide for indemnification of Covered Persons substantially identical in scope to that permitted under the Nevada Law. Such Bylaws provide that the expenses of directors and officers of Abraxas incurred in defending any action, suit or proceeding, whether civil, criminal, administrative or investigative, must be paid by Abraxas as they are incurred and in advance of the final disposition of the action, suit or proceeding, upon receipt of an undertaking by or on behalf of such director or officer to repay all amounts so advanced if it is ultimately determined by a court of competent jurisdiction that the director or officer is not entitled to be indemnified by Abraxas.
II-2
Abraxas has a contract for insurance coverage under which Abraxas and certain Covered Persons (including the directors and officers of Abraxas) are covered under certain circumstances with respect to litigation and other costs and liabilities arising out of actual or alleged misconduct of such Covered Persons. In addition, Abraxas has entered into indemnification agreements with its directors and officers that require Abraxas to indemnify such directors and officers to the fullest extent permitted by applicable provisions of Nevada law, subject to amounts paid by insurance. The above-described provisions of the Nevada Law relating to the indemnification of directors and officers do not prohibit the indemnification of such persons in certain circumstances against liabilities (including reimbursement of expenses incurred) arising under the Securities Act of 1933.
Our articles of incorporation contain a provision that eliminates the personal monetary liability of directors and officers to us and our stockholders asfor a resultbreach of any act or failurefiduciary duties to act in his capacity as a director or officer.the extent currently allowed under the Nevada Law.  To the extent certain claims against directors or officers are limited to equitable remedies, thesethis provision of our articles of incorporation may reduce the likelihood of derivative litigation and may discourage stockholders or management from initiating litigation against directors or officers for breach of their duty of care.  Additionally, equitable remedies may not be effective in many situations.  If a stockholder’s only remedy is to enjoin the completion of the Boardboard of Director’sdirector’s action, this remedy would be ineffective if the stockholder did not become aware of a transaction or event until after it had been completed.  In such a situation, it is possible that we and our stockholders would have no effective remedy against the directors or officers.
 
Liability for monetary damages has not been eliminated for acts or omissions which involve intentional misconduct, fraud or a knowing violation of law or payment of an improper dividend in violation of section 78.300 of the Nevada Statute.  The limitation of liability also does not eliminate or limit director liability arising in connection with causes of action brought under the Federal securities laws.
The Nevada Statute permits a corporation to indemnify certain persons, including officers and directors, who are (or are threatened to be made) parties to actions, suits or proceedings against all expenses (including attorneys’ fees) actually and reasonably incurred by, or imposed upon, him in connection with the defense by reason of his being or having been a director or officer if he acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful; provided, however, that indemnification may not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper.   The indemnification pursuant to the Nevada Statute and advancement of expenses authorized in or ordered by a court pursuant to the Nevada Statute does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under the articles of incorporation or any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in his official capacity or an action in another capacity while holding his office, except that indemnification, unless ordered by a court or for the advancement of expenses made pursuant to the Nevada Statute, may not be made to or on behalf of any director or officer if a final adjudication establishes that his acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and was material to the cause of action. Indemnification continues for a person who has ceased to be a director, officer, employee or agent and inures to the benefit of the heirs, executors and administrators of such a person. Abraxas’ bylaws provide indemnification to the same extent allowed pursuant to the foregoing provisions of the Nevada Statute.
II -1
Nevada corporations also are authorized to obtain insurance to protect officers and directors from certain liabilities, including liabilities against which the corporation cannot indemnify its directors and officers.  We currently have a directors’ and officers’ liability insurance policy in effect providing $10.0 million in coverage and an additional $1.0 million in coverage for certain employment related claims.
We have entered into indemnity agreements with each of our directors and officers.  These agreements provide for indemnification to the extent permitted by the Nevada Statute.

As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
(5)That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(6)For the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
