While this statute does not change directors&#8217; duty of care, it enables corporations to limit available relief to equitable remedies such as injunction or rescission. The statute has no effect on a director&#8217;s duty of loyalty or liability for acts or omissions not in good faith or involving intentional misconduct or knowing violations of law, illegal payment of dividends or stock redemptions or repurchases, or for any transaction from which the director derives an improper personal benefit. As permitted by the statute, the Registrant has adopted provisions in its certificate of incorporation that eliminate to the fullest extent permissible under Delaware law the personal liability of its directors to the Registrant and its stockholders for monetary damages for breach or alleged breach of their duty of care. The Registrant&#8217;s certificate of incorporation eliminates the personal liability of each of its directors for monetary damages resulting from any breach of his fiduciary duty as a director, except for liability:</font></div><table cellpadding="0" cellspacing="0" style="padding-bottom:16px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:48px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">for any breach of the director&#8217;s duty of loyalty to the Registrant or its stockholders; </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:16px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:48px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:16px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:48px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">under Section 174 of the Delaware General Corporation Law regarding unlawful dividends, stock purchases and redemptions; or </font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:16px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:11pt;padding-left:48px;"><font style="font-family:inherit;font-size:11pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">for any transaction from which the director derived an improper personal benefit. </font></div></td></tr></table><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify directors and officers as well as other individuals against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent to the Registrant.

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 1933 Act, (ii) to reflect in the prospectus any facts or events arising after the effective date of this 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 this 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 Securities Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the &#8220;Calculation of Registration Fee&#8221; table in the effective Registration Statement) and (iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) above shall not apply if the information required to be included in a post-effective amendment by those clauses 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 1934 Act that are incorporated by reference into this Registration Statement; (2) that for the purpose of determining any liability under the 1933 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 </font></div><div><br></div><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">at that time shall be deemed to be the initial bona fide offering thereof; and (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.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;">B.

Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers, or controlling persons of the Registrant pursuant to the indemnification provisions summarized in Item 6 or otherwise, the Registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by the final adjudication of such issue.</font></div><div><br></div><div><div style="line-height:120%;font-size:10pt;"><font

Item 4.    Description of securities

Item 5.    Interests of named experts and counsel
None.
Item 6.    Indemnification of directors and officers
Section 102(b) of the Delaware General Corporation Law authorizes a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach or alleged breach of the director's "duty of care." While this statute does not change directors' duty of care, it enables corporations to limit available relief to equitable remedies such as injunction or rescission. The statute has no effect on a director's duty of loyalty or liability for acts or omissions not in good faith or involving intentional misconduct or knowing violations of law, illegal payment of dividends or stock redemptions or repurchases, or for any transaction from which the director derives an improper personal benefit. As permitted by the statute, the Registrant has adopted provisions in its certificate of incorporation that eliminate to the fullest extent permissible under Delaware law the personal liability of its directors to the Registrant and its stockholders for monetary damages for breach or alleged breach of their duty of care. The Registrant's certificate of incorporation eliminates the personal liability of each of its directors for monetary damages resulting from any breach of his fiduciary duty as a director, except for liability:
•
for any breach of the director's duty of loyalty to the Registrant or its stockholders;
•
for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
•
under Section 174 of the Delaware General Corporation Law regarding unlawful dividends, stock purchases and redemptions; or
•
for any transaction from which the director derived an improper personal benefit.
Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify directors and officers as well as other individuals against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent to the Registrant. The Delaware General Corporation Law provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.
The Registrant's bylaws provide that:
•
the Registrant is required to indemnify its directors and officers, subject to limited exceptions in which such directors or officers are adjudged to be liable to the Registrant;
•
the Registrant is required to advance expenses, as incurred, to its directors and officers in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions; and
•
the rights conferred in the bylaws are not exclusive.
In addition, the Registrant has entered or will enter in the future into indemnity agreements with each of its current directors and officers. These agreements provide for the indemnification of the Registrant's officers and directors for all expenses and liabilities incurred in connection with any action or proceeding brought against them by reason of the fact that they are or were agents of the Registrant. At present, there is no pending litigation or proceeding involving a director, officer or employee of the Registrant regarding which indemnification is sought, nor is the Registrant aware of any threatened litigation that may result in claims for indemnification.
The Registrant also has obtained directors' and officers' insurance to cover its directors, officers and some of the Registrant's employees for liabilities, including coverage for public securities matters.
Reference is made to the underwriting agreement filed as Exhibit 1.1 to Registrant's Registration Statement on Form S-1 (Registration No. 333-141884), as amended, pursuant to which the underwriters have agreed to indemnify the Registrant's officers and directors against certain liabilities under the 1933 Act.

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 1933 Act, (ii) to reflect in the prospectus any facts or events arising after the effective date of this 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 this 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 Securities Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 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 this Registration Statement or any material change to such information in this Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) above shall not apply if the information required to be included in a post-effective amendment by those clauses 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 1934 Act that are incorporated by reference into this Registration Statement; (2) that for the purpose of determining any liability under the 1933 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; and (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 1933 Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is incorporated by reference into this 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 1933 Act may be permitted to directors, officers, or controlling persons of the Registrant pursuant to the indemnification provisions summarized in Item 6 or otherwise, the Registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the 1933 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 1933 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 Houston, State of Texas on this 19th day of January 2017.
