The General Corporation Law of the State of Delaware (the "DGCL") permits the Registrant and its stockholders to limit directors' exposure to liability for certain breaches of the directors' fiduciary duties, either in a lawsuit on behalf of the Registrant or in an action by stockholders of the Registrant. The Restated Certificate of Incorporation of the Registrant provides that a director of the Registrant shall not be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit.
The Amended and Restated Bylaws (the "Bylaws") of the Registrant provide that the Registrant shall, to the full extent permitted by applicable laws (including the DGCL), indemnify its directors, officers, employees and agents with respect to expenses (including counsel fees), judgments, fines, penalties, other liabilities and amounts incurred by any such person in connection with any threatened, pending or completed action, suit or proceeding to which such person is or was a party, or is or was threatened to be made a party, by reason of the fact that such person is or was serving as a director, officer, employee or agent of the Registrant or any of its subsidiaries, or is or was serving at the request of the Registrant or any of its subsidiaries as a director, officer, employee, agent or trustee of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. The Bylaws provide that the indemnification provided pursuant to the Bylaws is not exclusive of any other rights to which those seeking indemnification may be entitled under any provision of law, the certificate of incorporation, bylaws, governing documents, any agreement, any vote of stockholders or disinterested directors or otherwise.
The Registrant maintains an officers' and directors' liability insurance policy that provides coverage to the officers and directors of the Registrant for certain losses, damages, claims, liabilities and expenses, including certain liabilities that may arise out of this Registration Statement.

Item 9. Undertakings.
a)
The undersigned Registrant hereby undertakes:
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;
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 a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and
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) do not apply if 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 Exchange Act that are incorporated by reference in this 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.
4)
To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished,
provided
that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements.
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 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 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 on Form S-8 to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Houston, State of Texas on January 18, 2019.

Ladies and Gentlemen:
We have acted as counsel to ION Geophysical Corporation, a Delaware corporation (the "Company"), in  connection with the preparation of the Company's Registration Statement on Form S-8 (the "Registration  Statement") filed by the Company under the Securities Act of 1933, as amended (the "Securities Act"), with respect  to the issuance of up to an additional 1,200,000 shares of the Company's common stock (the "Shares"), $0.01 par value per share, under the Third Amended and Restated 2013 Long-Term Incentive Plan of the Company (the "Plan").
As the basis for the opinion hereinafter expressed, we examined the Plan, copies of the relevant corporate  resolutions of the Company and have examined originals or copies, certified or otherwise identified to our  satisfaction, of such corporate records and documents as we have deemed necessary as a basis for the opinions  hereinafter expressed.
In making our examination, we have assumed the authenticity and completeness of all records, certificates  and other instruments submitted to us as originals, the conformity to the original documents of all records,  certificates and other instruments submitted to us as copies, the authenticity and completeness of the originals of  those records, certificates and other instruments submitted to us as copies and the correctness of all statements of  fact contained in all records, certificates and other instruments that we have examined. We have also assumed the Registration Statement has been filed with the U.S. Securities and Exchange Commission and has become effective under the Securities Act.
Based on the foregoing, and having regard for such legal considerations as we have deemed relevant, we are of  the opinion that the Shares have been duly authorized and, when issued in accordance  with the terms of the Plan and the related award agreements thereunder, will be validly issued, fully paid and non-assessable.
The opinions expressed herein relate solely to, are based solely upon and are limited exclusively to the federal laws of the United States of America and the General Corporation Law of the State  of Delaware and the applicable provisions of the Delaware Constitution and reported judicial decisions concerning  such laws, and we express no opinion as to the effect of the laws of any other jurisdiction.
We hereby consent to the filing of this opinion as an exhibit to the Registration Statement.
Very truly yours,
