The Underwriters may exercise their option to acquire Option Shares in whole or in part from time to time only by written notice from RBC to the Company, given within a period of thirty (30) calendar days after the date of this Agreement and setting forth the aggregate number of Option Shares to be purchased and the date on which such Option Shares are to be delivered, as determined by RBC but in no event earlier than the Closing Date or, unless RBC and the Company otherwise agree in writing, earlier than one or later than five (5) business days after the date of such notice.

It is understood that the several Underwriters propose to offer the Firm Shares for sale to the public upon the terms and conditions set forth in the Prospectus.

3. Payment and Delivery. The Company will deliver the Firm Shares to RBC through the facilities of The Depository Trust Company (“DTC”) for the accounts of the Underwriters, against payment of the purchase price therefor in Federal (same day) funds by wire transfer drawn to the order of the Company at the offices of Andrews Kurth Kenyon LLP, 600 Travis Street, Suite 4200, Houston, Texas 77002, at 9:00 A.M., New York time, on March 15, 2017, or at such other time not later than seven (7) full business days thereafter as RBC and the Company may determine, such time being herein referred to as the “Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Firm Shares.

Each time for the delivery of and payment for the Option Shares, being herein referred to as an “Option Closing Date,” which may be the Closing Date, shall be determined by RBC and the Company as provided above. The Company will deliver the Option Shares being purchased on each Option Closing Date to RBC through the facilities of DTC for the accounts of the Underwriters, against payment of the purchase price therefor in Federal (same day) funds by wire transfer drawn to the order of the Company at the above office of Andrews Kurth Kenyon LLP, at 9:00 A.M., New York time on the applicable Option Closing Date.

(a) The Company agrees to indemnify and hold harmless each Underwriter and each of their directors, officers, employees, agents and representatives and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any post-effective amendment thereof, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement, as originally filed or any amendment thereof, the Registration Statement, or any post-effective amendment thereof, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof or any Issuer Free Writing Prospectus in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter is the information described as such in Section 8(b) of this Agreement.

(b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company and each of its directors, officers, employees, agents and representatives, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any post-effective amendment thereof, or any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus, to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement made therein in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of any Underwriter: (i) the selling concession figure set forth under the caption “Underwriting—Underwriting Discounts and Expenses” in the Pricing Disclosure Package and (ii) the information provided under the captions “Underwriting—Passive Market Making,” “Underwriting—Price Stabilization, Short Positions and Penalty Bids” and “Underwriting—Electronic Distribution” in the Pricing Disclosure Package.

(c) Promptly after receipt by an indemnified party under Section 8(a) or 8(b) of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 8). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and jointly with any other indemnifying party similarly notified, to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnified party). Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, which counsel, in the event of indemnified parties under Section 8(a), shall be selected by the Representative. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand and the Underwriter, on the other hand, from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Underwriters on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount pursuant to this Section 8(d) in excess of the sum of (i) any structuring fees paid to it hereunder and (ii) the underwriting discounts and commissions applicable to the Shares underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

The obligations of the parties to this Agreement contained in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

9. Increase in Underwriters’ Commitments. If any Underwriter or Underwriters default in its or their obligations to purchase Shares hereunder on the Closing Date or any Option Closing Date and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, the Representative may make arrangements satisfactory to the Company for the purchase of such Shares by other persons, including any of the other Underwriters, but if no such arrangements are made within 36 hours after such default, this Agreement will terminate, subject to the provisions of Section 10, without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. Nothing herein will relieve a defaulting Underwriter from liability for its default.

In the event of any such default, which does not result in a termination of this Agreement, either RBC or the Company shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven (7) days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9.

10. Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company or any of its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If this Agreement is terminated pursuant to Section 7 or 9 or if for any reason the purchase of any of the Shares by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 6, the respective obligations of the Company and the Underwriters pursuant to Section 8 and the provisions of Sections 10, 11 and 14 shall remain in effect.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Company and the Underwriters, the officers and directors of the Company referred to herein, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Shares from any Underwriter shall be deemed to be a successor or assign by reason merely of such purchase.

12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given upon receipt thereof by the recipient if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representative, c/o RBC Capital Markets, LLC, 200 Vesey Street, 10th Floor, New York, New York 10281 (fax no.: 212-658-6137); Attention: DCM Transaction Management.

No other Person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

17. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the purchase price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection therewith and with the process leading to such transaction each Underwriter is and has been acting solely as a principal and not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (c) other than FBR Capital Markets & Co. (“FBR”), no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of each of the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

18. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriter’s investment banking divisions.

19. Tax Disclosure. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

20. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof

21. RIGHT TO TRIAL BY JURY. Each of the Company and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Cumulative Redeemable Perpetual Preferred Shares

Number of Option Shares:	210,000 shares of Series A Preferred Stock.
Trade Date:	March 8, 2017.
Settlement and Delivery Date:	March 15, 2017 (T + 5).
Public Offering Price:	$25.00 per share of Series A Preferred Stock; $35,000,000 total (assuming no exercise of the underwriters’ option to purchase additional shares of Series A Preferred Stock).
Underwriting Discount:	$0.7875 per share; $1,102,500 total (assuming no exercise of the underwriters’ option to purchase additional shares of Series A Preferred Stock).
Maturity Date:	Perpetual (unless redeemed by Issuer on or after April 15, 2022 or in connection with a change of control).
Rating:	The Series A Preferred Stock will not be rated.



Dividend Rate:	From, and including, the date of original issuance to, but not including, April 15, 2022, at an annual rate of 8.75%, based on the $25.00 liquidation preference per annum. On and after April 15, 2022 at an annual rate equal to the sum of (a) Three-Month LIBOR (as defined below) as calculated on each applicable Date of Determination (as defined below) and (b) 6.578%, based on the $25.00 liquidation preference per share of Series A Preferred Stock. The term “Three-Month LIBOR” means, on the second Business Day in London immediately preceding the first day of each relevant Dividend Period (as defined below under “Dividend Payment Date”) for the Series A Preferred Stock, or if applicable, the redemption date (the “Date of Determination”): o the rate (expressed as a percentage per year) for deposits in U.S. dollars having an index maturity of three months, in amounts of at least $1,000,000, as such rate appears on “Reuters Page LIBOR01” at approximately 11:00 a.m. (London time) on such Date of Determination; or o if no such rate appears on “Reuters Page LIBOR01” or if the “Reuters Page LIBOR01” is not available at approximately 11:00 a.m. (London time) on the relevant Date of Determination, then the Issuer will select four nationally-recognized banks in the London interbank market and request that the principal London offices of those four selected banks provide the Issuer with their offered quotation for deposits in U.S. dollars for a period of three months, commencing on the first day of the applicable Dividend Period, to prime banks in the London interbank market at approximately 11:00 a.m. (London time) on that Date of Determination for the applicable Dividend Period. Offered quotations must be based on a principal amount equal to an amount that, in the Issuer’s discretion, is representative of a single transaction in U.S. dollars in the London interbank market at that time. If at least two quotations are provided, the Three-Month LIBOR Rate for such Dividend Period will be the arithmetic mean (rounded upward if necessary, to the nearest 0.00001 of 1%) of those quotations. If fewer than two quotations are provided, the Three-Month LIBOR Rate for such Dividend Period will be the arithmetic mean (rounded upward if necessary, to the nearest 0.00001 of 1%) of the rates quoted at approximately 11:00 a.m. (New York City time) on that Date of Determination for such Dividend Period by three nationally-recognized banks in New York, New York selected by the Issuer, for loans in U.S. dollars to nationally-recognized European banks (as selected by the Issuer), for a period of three months commencing on the first day of such Dividend Period. The rates quoted must be based on an amount that, in the Isuer’s discretion, is representative of a single transaction in U.S. dollars in that market at that time. If fewer than three New York City banks selected by the Issuer do not quote rates in the manner described above, the Three-Month LIBOR Rate for the applicable Dividend Period will be the same as for the immediately preceding Dividend Period, or, if there was no such Dividend Period, the dividend shall be calculated at the dividend rate in effect for the immediately preceding Dividend Period.



Dividend Payment Date:	Dividends on the Series A Preferred Stock shall accrue daily and be cumulative from, and including, the date of original issue and shall be payable quarterly on the 15th day of each of April, July, October and January (each such payment date, a “Dividend Payment Date,” and each such quarterly period, a “Dividend Period”); provided that if any Dividend Payment Date is not a Business Day, then the dividend which would otherwise have been payable on that Dividend Payment Date may be paid on the next succeeding Business Day, and no interest, additional dividends or other sums will accrue on the amount so payable for the period from and after that Dividend Payment Date to that next succeeding Business Day. The first dividend on the Series A Preferred Stock is scheduled to be paid on July 15, 2017 in the amount of $0.72917 per share of Series A Preferred Stock to the persons who are the holders of record of the Series A Preferred Stock at the close of business on July 1, 2017.
Liquidation Preference:	$25.00 per share of Series A Preferred Stock, plus accumulated and unpaid dividends.
Optional Redemption Date:	On and after April 15, 2022, for cash at a redemption price of $25.00 per share of Series A Preferred Stock, plus any accumulated and unpaid dividends thereon to, but not including, the date fixed for redemption.
Special Optional Redemption:	Upon the occurrence of a Change of Control, provided no Limiting Document may prohibit it, the Issuer may, at its option, upon not less than thirty (30) days nor more than sixty (60) days’ written notice, redeem the Series A Preferred Stock, in whole or in part, within one hundred twenty (120) days after the first date on which such Change of Control occurred, for cash at a redemption price of $25.00 per share, plus any accumulated and unpaid dividends thereon to, but not including, the date fixed for redemption. If, prior to the Change of Control Conversion Date, the Issuer provided notice of its election to redeem some or all of the shares of Series A Preferred Stock (whether pursuant to the Issuer’s optional redemption right described above or this special optional redemption right), the holders of shares of Series A Preferred Stock will not have the Change of Control Conversion Right with respect to the shares called for redemption. If the Issuer elects to redeem any shares of the Series A Preferred Stock as described in this paragraph, it may use any available cash to pay the redemption price.



Limited Conversion Rights Upon a Change of Control:	Upon the occurrence of a Change of Control, each holder of shares of Series A Preferred Stock will have the right (unless, prior to the Change of Control Conversion Date, the Issuer has provided or provides irrevocable notice of its election to redeem the Series A Preferred Stock, in which case such holder will only have the right with respect to the shares of Series A Preferred Stock not called for redemption (unless the Issuer defaults in the payment of the redemption price and accumulated and unpaid dividends in which case such holder will again have a conversion right with respect to the shares of Series A Preferred Stock subject to such default in payment)) to convert some or all of the shares of Series A Preferred Stock held by such holder on the Change of Control Conversion Date into a number of shares of the Issuer’s Class A common stock per share of Series A Preferred Stock, which is equal to the lesser of: • the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference per share of Series A Preferred Stock plus the amount of any accumulated and unpaid dividends (whether or not declared) to, but not including, the Change of Control Conversion Date (unless the Change of Control Conversion Date is after a record date for a Series A Preferred Stock dividend payment and prior to the corresponding Dividend Payment Date, in which case no additional amount for such accumulated and unpaid dividend will be included in this sum) by (ii) the Common Stock Price; and • 1.834862 shares of Class A common stock (the “Share Cap”), subject to certain adjustments described in the prospectus supplement. The Share Cap was derived by dividing the $25.00 liquidation preference by $13.625 (50% of the last sale price of our Class A common stock as reported on the NASDAQ on March 7, 2017).

m.	The Company is not an “investment company” within the meaning of said term as used in the Investment Company Act of 1940, as amended.

In addition, we have participated in conferences with officers and other representatives of the Company, the independent registered public accounting firm for the Company, your counsel and your representatives, at which the contents of the Registration Statement, the Disclosure Package

Exhibit A-2

and the Prospectus (including any of the Company’s reports that have been filed with the Commission and are incorporated by reference in the Registration Statement (the “Incorporated Documents”)) and related matters were discussed and, although we have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus (except as and to the extent set forth in paragraph 12 above), on the basis of the foregoing (relying with respect to factual matters to the extent we deem appropriate upon statements by officers and other representatives of the Company), (a) we confirm to you that, in our opinion, each of the Registration Statement, as of its most recent effective date, the Preliminary Prospectus, as of its date, and the Prospectus, as of its date, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the General Rules and Regulations thereunder (except that we express no statement or belief as to Regulation S-T), (b) we have not become aware of any documents that are required to be filed as exhibits to the Registration Statement or any of the Incorporated Documents and are not so filed or of any documents that are required to be summarized in the Preliminary Prospectus or the Prospectus or any of the Incorporated Documents, and are not so summarized and (c) furthermore, no facts have come to our attention that have led us to believe that (i) the Registration Statement, as of its most recent effective date, insofar as relating to the offering of the Shares, contained an untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Disclosure Package (including the Incorporated Documents), as of 4:45 p.m., New York city time, on March 8, 2017 (which you have informed us is a time prior to the time of the first sale of the Firm Shares by any Underwriter), insofar as relating to the offering of the Shares, contained an untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) the Prospectus (including the Incorporated Documents), as of its date and as of the date hereof, insofar as relating to the offering of the [Firm] Shares, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that we did not participate in the preparation of the Incorporated Documents and that we express no opinion, statement or belief in this letter with respect to (i) the historical and pro forma financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon, (ii) any other financial, statistical or accounting data, included or incorporated or deemed incorporated by reference in, or excluded from, the Registration Statement or the Prospectus or the Disclosure Package, (iii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement or Incorporated Documents and (v) the exclusion from the Disclosure Package of any pricing information (and directly related disclosure) included in the Prospectus.

Furthermore, we advise you that according to the effectiveness order of the SEC (regarding the Registration Statement) appearing in the SEC’s Electronic Data Gathering, Analysis, and Retrieval system, the Registration Statement was declared effective under the Securities Act on October 20, 2016. In addition, based solely on our review of the information made available by the SEC at http://www.sec.gov/litigation/stoporders.shtml, we confirm that the SEC has not issued any stop order suspending the effectiveness of the Registration Statement. To our knowledge, based

Exhibit A-3

solely on our participation in the conferences mentioned above regarding the Registration Statement, no proceedings for that purpose are pending or have been instituted or threatened by the SEC.

We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of New York, (ii) applicable laws of the State of Texas, (iii) applicable laws of the United States of America, (iv) the DGCL, and (v) the Delaware LLC Act. References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Underwriting Agreement without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation those appearing in paragraphs 10 and 11 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws, rules or regulations.
