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.

Item 6.
Indemnification of Directors and Officers.
Subsection 7 of Section 78.138 of the Nevada Revised Statutes (the "Nevada Law") provides 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 even if there is a provision in the corporation's articles of incorporation unless an amendment to Abraxas' Articles of Incorporation 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 Covered Person's 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 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 a criminal or civil 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 indemnification 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.
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 for a breach of fiduciary duties to the extent currently allowed under the Nevada GCL.  To the extent certain claims against directors or officers are limited to equitable remedies, this 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 Board of Director'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.

Item 9.
Undertakings.
(a)
The Registrant undertakes the following:
1.
To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the "
Securities Act
");
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement.  Notwithstanding the
foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement;
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the registration statement is on Form S-8 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") that are incorporated by reference in the Registration Statement.
2.
That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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.
3.
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)
The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) 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.
(c)
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Antonio, State of Texas, on June 5, 2015.
