(ii) there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Prospectus that, in your judgment, is material and adverse and that makes it, in your judgment, impracticable to market the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus.

(b) The Underwriters shall have received on the Closing Date a certificate, dated the Closing Date and signed by an executive officer of the Company, to the effect set forth in Section 6(a) above and to the effect that the representations and warranties of the Company contained in this Agreement are true and correct as of the Closing Date and that the Company has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before the Closing Date.

(a) To furnish to you if requested, without charge, four (4) signed copies of the Registration Statement (excluding exhibits thereto) and to furnish to you in New York City, without charge, prior to 10:00 a.m. New York City time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 7 (e) or 7 (f) below, as many copies of the Time of Sale Prospectus, the Prospectus and any supplements and amendments thereto or to the Registration Statement as you may reasonably request.

(b) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, to furnish to you a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which you reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule.

(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the reasonable opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Company) to which Shares may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(g) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request; provided, that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified.

(h) To make generally available to the Company’s security holders and to you as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(i) If the Selling Shareholder is not a U.S. person for U.S. federal income tax purposes, the Company will deliver to each Underwriter (or its agent), on or before the Closing Date, (i) a certificate with respect to the Company’s status as a “United States real property holding corporation,” dated not more than thirty (30) days prior to the Closing Date, as described in Treasury Regulations Sections 1.897-2(h) and 1.1445-2(c)(3), and (ii) proof of delivery to the IRS of the required notice, as described in Treasury Regulations 1.897-2(h)(2).

(j) The Company will promptly notify the Underwriters if the Company ceases to be a an “emerging growth company,” as defined in Section 2(a) of the Securities Act (an “Emerging Growth Company”) at any time prior to the later of (a) completion of the distribution of the Shares within the meaning of the Securities Act and (b) completion of the Restricted Period referred to in Section 3.

The provisions of this Section shall not supersede or otherwise affect any agreement that the Selling Shareholder may otherwise have for the allocation of such expenses among themselves.

10. Covenants of the Underwriters. Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

11. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the Selling Shareholder, each person, if any, who controls any Underwriter or the Selling Shareholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter or the Selling Shareholder within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a

“road show”), or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein.

(b) The Selling Shareholder agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein or based upon the information relating to the Selling Shareholder furnished to the Company in writing by the Selling Shareholder expressly for use therein, it being understood and agreed that (1) the only information relating to the Selling Shareholder, furnished by the Selling Shareholder consists of the following information in the Time of Sale Prospectus and Prospectus: the name of the Selling Shareholder and the beneficial ownership information (excluding percentages) and number of Shares being sold by the Selling Shareholder, each as described under the caption “Principal and Selling Shareholder” (the “Shareholder Information”) and (2) the liability of the Selling Shareholder under the indemnity and contribution provisions contained in Section 8 and this Section 11 shall be limited to an amount equal to the net proceeds (but before expenses), to the Selling Shareholder from the sale of Shares sold by the Selling Shareholder (with respect to the Selling Shareholder, the “Selling Shareholder Amount”).

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Selling Shareholder, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or the Selling Shareholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or

other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show, or the Prospectus or any amendment or supplement thereto.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a), 11 (b) or 11(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party shall be entitled to participate in such proceeding and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and, except as provided in the following sentence, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholder and all persons, if any, who control the Selling Shareholder within the meaning of either such Section, and that all such fees and

expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Underwriters. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholder and such control persons of the Selling Shareholder, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Shareholder under the Powers of Attorney. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(e) To the extent the indemnification provided for in Section 11(a), 11(b) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 11(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholder on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each of the Company and Selling Shareholder and the total underwriting discounts and commissions received by the Underwriters bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company and the Selling Shareholder on the one hand and the Underwriters on the other hand 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 or the Selling Shareholder or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 11 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(f) The Company and the Selling Shareholder and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 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 that does not take account of the equitable considerations referred to in Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(e) shall be deemed to include, subject to the limitations set forth above, 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 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(e) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 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.

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and the Selling Shareholder contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, the Selling Shareholder or any person controlling the Selling Shareholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

12. Termination. The Underwriters may terminate this Agreement by notice given by you to the Company and the Selling Shareholder, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over the counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred or other relevant jurisdiction, (iv) any moratorium on commercial banking activities shall

have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Underwriters’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

13. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to you, the Company and the Selling Shareholder for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Shareholder. In any such case either you or the relevant Sellers shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Selling Shareholder to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any Seller shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all reasonably incurred out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

14. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and the Selling Shareholder, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length with, are not agents of, and owe no fiduciary duties to, the Company or any other person, (ii) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company. The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

Re: Public Offering of Common Stock by Wingstop Inc.

Ladies and Gentlemen:

We have acted as counsel for Wingstop Inc., a Delaware corporation (the “Company”), in connection with the sale of [•] shares (the “Shares”) of the Company’s Common Stock, par value $0.01 per share (the “Common Stock”), by RC II WS LLC (the “Selling Stockholder”) to you pursuant to an Underwriting Agreement (the “Underwriting Agreement”), dated November [•], 2016, among you, the Company and the Selling Stockholder. This opinion is being rendered at the Company’s and the Selling Stockholder’s request pursuant to Section 6(c) of the Underwriting Agreement. Capitalized terms used in this opinion and not otherwise defined herein shall have the meanings given to such terms in the Underwriting Agreement.

As used herein, the term (i) “Registration Statement” means the “shelf registration statement” (as defined in Rule 405 under the Securities Act) on Form S-3 (Registration No. 333- 212393) in the form in which it became effective on July 25, 2016, including the information deemed to be a part thereof pursuant to Rule 430A, 430B or 430C under the Securities Act to be part thereof at the time of its effectiveness, together with the documents incorporated by reference therein, (ii) “Preliminary Prospectus” means the preliminary prospectus supplement dated [ • ], 2016 filed by the Company pursuant to Rule 424(b) and the prospectus included in the Registration Statement at the time of its effectiveness, together with the documents incorporated by reference therein, (iii) “Prospectus” means the final prospectus supplement dated [•], 2016, filed by the Company pursuant to Rule 424(b), together with the documents incorporated by reference therein and (iv) “Time of Sale Prospectus” means the Preliminary Prospectus together with the pricing information set forth on Schedule III to the Underwriting Agreement.

In our capacity as counsel to the Company, we have reviewed (i) the Registration Statement, (ii) the Preliminary Prospectus, (iii) the Prospectus and (iv) the Underwriting Agreement. We have also reviewed such matters of law and examined original, certified, conformed or photographic copies of such other documents, records, agreements and certificates as we have deemed necessary as a basis for the opinions hereinafter expressed. In such review we have assumed the genuineness of signatures on all documents submitted to us as originals and the conformity to original documents of all copies submitted to us as certified, conformed or photographic copies. We have relied, as to the matters set forth therein, on certificates of public officials.

As to certain matters of fact material to this opinion, we have relied to the extent we deemed appropriate, without independent verification, upon (i) certificates of officers of the Company and (ii) the representations and warranties of the Company and the Selling Stockholder in the Underwriting Agreement. Whenever our opinion in this letter is stated to be based upon our knowledge, such qualification shall signify that no information has come to the attention of the attorneys in our firm who have been involved in the preparation or review of the Registration Statement, the Prospectus or this opinion or that regularly provide advice to the Company and its subsidiaries and the Selling Stockholder that would give us actual current knowledge of the existence or absence of the matter in question.

Based upon the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that:

(1) the Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the state of Delaware, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and is duly qualified to transact business in the jurisdictions listed on Schedule I attached hereto and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole;

(2) each subsidiary of the Company listed on Schedule II attached hereto (each a “Subsidiary”) has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and is duly qualified to transact business in the jurisdictions listed on Schedule II and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole;

(3) the authorized capital stock of the Company conforms as to legal matters to the description thereof contained in each of the Time of Sale Prospectus and the Prospectus;

(4) the shares of Common Stock (including the Shares to be sold by the Selling Stockholder) outstanding have been duly authorized and are validly issued, fully paid and non-assessable;

(5) to our knowledge, all of the issued shares of capital stock of each Subsidiary of the Company have been duly and validly authorized and issued, are fully paid and non-assessable and, except as described in the Time of Sale Prospectus, are owned directly by the Company, free and clear of all liens, encumbrances, equities or claims;

(6) the Underwriting Agreement has been duly authorized, executed and delivered by the Company;

(7) the execution and delivery by the Company of, and the performance by the Company of its obligations under, this Agreement will not contravene any provision of applicable law or the certificate of incorporation or by-laws of the Company or any agreement or other instrument that is filed as an exhibit to the Registration Statement, or, to our knowledge, any judgment, order or decree of any governmental body, agency or court known by us to have jurisdiction over the Company or any Subsidiary, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under this Agreement, except such as may have been obtained or may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Shares;

(8) the statements relating to legal matters, documents or proceedings included in (A) the Time of Sale Prospectus and the Prospectus under the captions “Description of Capital Stock” and “Shares Eligible for Future Sale” and (B) the Registration Statement in Items 14 and 15, in each case fairly summarize in all material respects such matters, documents or proceedings;

(9) we do not know of any legal or governmental proceedings pending or threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject that are required to be described in the Registration Statement or the Prospectus and are not so described or of any statutes, regulations, contracts or other documents that are required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required;

(10) the Company is not required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended;

(11) the Registration Statement, including any information deemed to be a part thereof pursuant to Rule 430B, the Preliminary Prospectus and the Prospectus, excluding the documents incorporated by reference therein, and each amendment or supplement to the Registration

Statement, the Preliminary Prospectus and the Prospectus, as of their respective effective or issue dates, appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder; except that we do not express any opinion on (A) the financial statements and notes thereto and the other financial information included or incorporated by reference therein or omitted therefrom, or (B) the representations and warranties and other statements of fact included in the exhibits to the Registration Statement;

(12) the documents incorporated by reference in the Prospectus (other than the financial statements and related schedules and other financial information contained or incorporated by reference therein, as to which we express no belief), when they were filed with the Commission complied as to form in all material respects with the requirements of the Exchange Act;

(13) the Underwriting Agreement has been duly authorized, executed and delivered by or on behalf of the Selling Stockholder;

(14) the execution and delivery by the Selling Stockholder of, and the performance by such Selling Stockholder of its obligations under, this Agreement will not contravene any provision of applicable law, the limited liability company agreement or certificate of formation of such Selling Stockholder, or, to our knowledge, any material agreement or other instrument binding upon the Selling Stockholder or, to our knowledge, any judgment, order or decree of any governmental body, agency or court known by it to have jurisdiction over the Selling Stockholder, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Selling Stockholder of its obligations under this Agreement, except such as has already been obtained or as may be required by the securities or Blue Sky laws of the various states in connection with offer and sale of the Shares;

(15) the Selling Stockholder has valid title to, or a valid security entitlement in respect of, the Shares to be sold by the Selling Stockholder free and clear of all security interests, claims, liens, equities and other encumbrances, and the Selling Stockholder has the legal right and power, and all authorization and approval required by law, to enter into this Agreement and to sell, transfer and deliver the Shares to be sold by the Selling Stockholder or a security entitlement in respect of such Shares;

(16) upon payment for the Shares to be sold by the Selling Stockholder pursuant to this Agreement, delivery of such Shares, as directed by the Underwriter, to Cede or such other nominee as may be designated by DTC, registration of such Shares in the name of Cede or

such other nominee and the crediting of such Shares on the books of DTC to securities accounts of the Underwriter (assuming that neither DTC nor the Underwriter has notice of any adverse claim within the meaning of Section 8-105 of the UCC to such Shares), (A) DTC shall be a “protected purchaser” of such Shares within the meaning of Section 8-303 of the UCC, (B) under Section 8-501 of the UCC, the Underwriter will acquire a valid security entitlement in respect of such Shares and (C) no action based on any “adverse claim” (within the meaning of Section 8-102 of the UCC) to such Shares may be asserted against the Underwriter with respect to such security entitlement; in giving this opinion, we assume that when such payment, delivery and crediting occur, (x) such Shares will have been registered in the name of Cede or another nominee designated by DTC, in each case on the Company’s share registry in accordance with its certificate of incorporation, bylaws and applicable law, (y) DTC will be registered as a “clearing corporation” within the meaning of Section 8-102 of the UCC and (z) appropriate entries to the accounts of the Underwriter on the records of DTC will have been made pursuant to the UCC.

We have participated in conferences with representatives of the Company, representatives of the Underwriter and their counsel and representatives of Ernst & Young LLP, the independent public accountants of the Company, during which the contents of the Registration Statement, the Time of Sale Prospectus and the Prospectus and any amendment and supplement thereto and related matters were discussed and reviewed; although we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Prospectus and any amendment or supplement thereto (except as expressly provided in paragraph 8 above) or the Prospectus, on the basis of the information that was developed in the course of the performance of the services referred to above, nothing has come to our attention that causes us to believe that: (A) the Registration Statement, as of the time it became effective (including the information, if any, deemed pursuant to Rule 430A, 430B or 430 C to be part of the Registration Statement at the time of effectiveness), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; (B) the Time of Sale Prospectus, at the time of sale of the Shares, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (C) the Prospectus, as of its date or as amended or supplemented, if applicable, or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that, with respect to clauses (A), (B) and (C) above, we do not express any opinion or belief with respect to the financial statements and notes thereto and the other financial information included or incorporated by reference therein or omitted therefrom.

This opinion is delivered in connection with the consummation of the transactions contemplated by the Underwriting Agreement, may be relied upon only by you in connection therewith, may not be relied upon by you for any other purpose or by anyone else for any purpose, except that Computershare Trust Company, N.A. may rely on this opinion in its capacity as transfer agent, and may not be quoted, published or otherwise disseminated without our prior written consent.

This opinion is limited in all respects to the federal laws of the United States of America, the laws of the States of New York, Texas and Georgia and the General Corporation Law of the State of Delaware, and no opinion is expressed with respect to the laws of any other jurisdiction or any effect that such laws may have on the opinions expressed herein. This opinion is limited to the matters stated herein, and no opinion is implied or may be inferred beyond the matters expressly stated herein.

This opinion is given as of the date hereof, and we assume no obligation to update this opinion letter to reflect any facts or circumstances that may hereafter come to our attention or any changes in any laws or regulations which may hereafter occur.
