ITEM 15.	Indemnification of Directors and Officers	
The general effect of the following provisions is to provide indemnification to officers, directors and control persons for liabilities that may arise by reason of their status as officers, directors or control persons, other than liabilities arising from willful or intentional misconduct, acts or omissions not in good faith, unlawful distributions of corporate assets or transactions from which the officer or manager derived an improper personal benefit.
Delaware Registrants
Delaware Corporations
Concho and RSP are organized as corporations in the State of Delaware. Section 145 of the Delaware General Corporation Law (“DGCL”) provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Section 145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the
 
II-1

extent that the Delaware Court of Chancery or such other court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper.
Delaware law provides that directors of a corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of their fiduciary duties as directors, except for liability:
 
 	•	 	for any breach of their duty of loyalty to the corporation or its stockholders;	
 
 	•	 	for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;	
 
 	•	 	under Section 174 of the DGCL relating to unlawful payments of dividends or unlawful stock repurchases or redemptions; or	
 
 	•	 	for any transaction from which the director derived an improper personal benefit.	
Our Restated Certificate of Incorporation provides that we shall indemnify our officers and directors to the extent provided in our Fourth Amended and Restated Bylaws (our “Bylaws”). In turn, our Bylaws provide that we will indemnify and hold harmless, to the full extent permitted by the DGCL, any of our officers or directors (including those persons serving as an officer or director of another entity at our request) who is party to a suit or other proceeding by reason of his or her position as an officer or director against all reasonably incurred expense, liability or loss. We may only indemnify an officer or director who brought the suit or proceeding if our board of directors had previously authorized such suit or proceeding. The rights to indemnification provided by our Bylaws include the right to advancement of expenses to the full extent permitted by the DGCL. In addition, our Bylaws allow us to indemnify our non-officer employees and agents to the extent (i) permitted by the DGCL and (ii) authorized by our Chief Executive Officer and at least one other authorized officer.
We have also entered into indemnification agreements with all of our directors and executive officers. These indemnification agreements are intended to permit indemnification to the fullest extent now or hereafter permitted by the DGCL. It is possible that the applicable law could change the degree to which indemnification is expressly permitted.
The indemnification agreements cover expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement incurred as a result of the fact that such person, in his or her capacity as a director or officer, is made or threatened to be made a party to any suit or proceeding. The indemnification agreements generally cover claims relating to the fact that the indemnified party is or was an officer, director, employee or agent of us or any of our affiliates, or is or was serving at our request in such a position for another entity. The indemnification agreements also obligate us to promptly advance all reasonable expenses incurred in connection with any claim. The indemnitee is, in turn, obligated to reimburse us for all amounts so advanced if it is later determined that the indemnitee is not entitled to indemnification. The indemnification provided under the indemnification agreements is not exclusive of any other indemnity rights; however, double payment to the indemnitee is prohibited.
We are not obligated to indemnify the indemnitee with respect to claims brought by the indemnitee against us or our directors or officers without approval by our board of directors, except for claims regarding the indemnitee’s rights under the indemnification agreement.
We have obtained director and officer liability insurance for the benefit of each of the indemnitees. These policies include coverage for losses for wrongful acts and omissions and to ensure our performance under the indemnification agreements. Each of the indemnitees are insured under such policies and provided with the same rights and benefits as are accorded to the most favorably insured of our directors and officers.
 
II-2

The Second Amended and Restated Bylaws of RSP provide that RSP will indemnify and hold harmless, to the full extent permitted by the DGCL, any of its officers, directors, employees or agents (including those persons serving as an officer, director, employee or agent of another entity at RSP’s request) who is party to a suit or other proceeding by reason of his or her position as an officer or director against all reasonably incurred expenses unless RSP determines that such person (i) did not act in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of RSP or, (ii) with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful. RSP may only indemnify an individual if such person gave notice to RSP within six months of the right to receive indemnification or advance payment or reimbursement.
Delaware Limited Liability Companies
COG Operating LLC, Mongoose Minerals LLC and RSP LLC are organized as limited liability companies in the State of Delaware. Section 18-108 of the Delaware Limited Liability Company Act provides that, subject to such standards and restrictions, if any, as are set forth in its limited liability company agreement, a Delaware limited liability company may, and has the power to, indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever.
The limited liability company agreement of COG Operating LLC provides that COG Operating LLC will indemnify and hold harmless us and our affiliates and respective stockholders, members, managers, directors, officers, employees and agents against any loss, expense or damage arising out of activities on behalf of COG Operating LLC or in furtherance of the interests of COG Operating LLC; provided, that the acts or omissions upon which such proceeding or claim is based were not a result of fraud or willful misconduct by the indemnified person. The rights to indemnification provided by the limited liability company agreement of COG Operating LLC include the right to advancement of expenses; provided, that the indemnified person shall reimburse such advances if it is later determined such indemnified person was not entitled to indemnification with respect to such action or proceeding.
The limited liability company agreement of Mongoose Minerals LLC provides that Mongoose Minerals LLC will indemnify and hold harmless (i) its members, officers, directors, employees, affiliates, representatives or agents and (ii) any officer, employee, representative or agent of Mongoose Minerals LLC against any loss, liability, damage, expense or claim arising out of any act or omission of such indemnified person in connection with its management of the affairs of Mongoose Minerals LLC or which relate to Mongoose Minerals LLC or its property, business or affairs; provided, that such acts or omissions do not constitute bad faith, gross negligence or willful misconduct by the indemnified person.
The limited liability company agreement of RSP LLC provides that RSP LLC will indemnify and hold harmless (i) its members, officers, directors, employees, affiliates, representatives or agents and (ii) any officer, employee, representative or agent of RSP LLC against any loss, liability, damage, judgment, demand, expense or claim arising out of any act or omission of such indemnified person in connection with its management of the affairs of RSP LLC or which relate to RSP LLC or its property, business or affairs; provided, that such acts or omissions do not constitute bad faith, gross negligence or willful misconduct by the indemnified person.
Texas Registrants
Pursuant to Section 1.106 of the Texas Business Organizations Code (the “TBOC”), the indemnification provisions set forth in the TBOC are applicable to most entities established in the State of Texas, including corporations, limited liability companies and limited partnerships. Under Section 8.002 of the TBOC, unless a Texas limited liability company adopts the general indemnification provisions of the TBOC, described below, those provisions are not applicable to a Texas limited liability company.
 
II-3

Pursuant to Section 8.051 of the TBOC, an enterprise must indemnify a governing person, former governing person or delegate against reasonable expenses actually incurred by the person in connection with a proceeding in which the person was a respondent because the person is or was a governing person if the person is wholly successful, on the merits or otherwise, in the defense of the proceeding. Pursuant to Sections 8.101 and 8.102 of the TBOC, any governing person, former governing person or delegate of a Texas enterprise may be indemnified against judgments and reasonable expenses actually incurred by the person in connection with a proceeding, in which such person was a respondent if it is determined, in accordance with Section 8.103 of the TBOC, that: (i) the person acted in good faith, (ii) the person reasonably believed (a) in the case of conduct in the person’s official capacity, that the person’s conduct was in the enterprise’s best interests or (b) in any other case, that the person’s conduct was not opposed to the enterprise’s best interests, (iii) in the case of a criminal proceeding, such person did not have a reasonable cause to believe that the person’s conduct was unlawful and (iv) the indemnification should be paid. Indemnification of a person who is found to be liable to the enterprise is limited to reasonable expenses actually incurred by the person in connection with the proceeding and does not include judgments, penalties or fines, except for certain circumstances where indemnification cannot be given at all. Pursuant to Section 8.105 of the TBOC, an enterprise may indemnify an officer, employee or agent to the same extent that indemnification is required under the TBOC for a governing person or as provided in the enterprise’s governing documents, general or specific action of the enterprise’s governing authority, contract or by other means.
Texas Limited Liability Companies
Pursuant to Section 101.402 of the TBOC, a Texas limited liability company may indemnify a member, manager or officer of a limited liability company, pay in advance or reimburse expenses incurred by a member, manager or officer and establish and maintain insurance or another arrangement to indemnify or hold harmless a member, manager or officer.
COG Holdings LLC, COG Production LLC, COG Realty LLC, Concho Oil & Gas LLC, Delaware River SWD LLC and Quail Ranch LLC are organized as limited liability companies in the State of Texas (the “Texas LLC Registrants”). The limited liability company agreements of COG Realty LLC and Quail Ranch LLC provide that each entity will indemnify and hold harmless, to the full extent permitted by the TBOC, each of its, in the case of COG Realty LLC, managers and, in the case of Quail Ranch LLC, officers, who is or is threatened to be made party to a suit or other proceeding by reason of his or her position as a manager or officer, as applicable, and is acting within the scope of his or her duties under the authority of such entity’s members.
Additionally, the limited liability company agreements of COG Holdings LLC, COG Production LLC, Concho Oil & Gas LLC, and Delaware River SWD LLC provide that each entity shall indemnify and hold harmless, to the full extent permitted by the TBOC, any of their current or former (i) officers and (ii) members and each of their respective affiliates, stockholders, partners, members, directors, managers, officers, liquidators and employees from and against any loss, expense, damage or injury suffered or sustained by reason of acts, omissions or alleged acts or omissions that result from, arise in connection with or are by reason of (x) the activities of such entity and its affiliates, (y) anything done or not done by the indemnified person in its capacity as an indemnified person or (z) the fact that the indemnified person was an indemnified person; provided, that such right shall not apply if the applicable proceeding has been brought by or in the right of such entity unless related to the indemnified person’s participation in certain proceedings. Additionally, such entities shall indemnify and hold harmless, to the full extent permitted by the TBOC, such indemnified persons from and against all expenses reasonably incurred in connection with the defense or settlement of any proceeding by or in the right of such entity if the indemnified person acted in good faith and in a manner it reasonably believed to be in (or not opposed to) the best interests of the entity; provided, that no such indemnification shall be made where the indemnified person was adjudged to be liable to the entity unless the court in which such proceeding shall have been brought or is pending determines that, despite such adjudication of liability and in light of all circumstances, such indemnification may be made.
 
II-4

The rights to indemnification provided by the limited liability company agreements of each of the Texas LLC Registrants include the right to advancement of expenses to the fullest extent permitted by the TBOC related to the indemnified person’s participation in certain proceedings; provided, except in the case of Quail Ranch LLC and COG Realty LLC, that the indemnified person shall reimburse such advances if it is later determined such indemnified person was not entitled to indemnification with respect to such action or proceeding.

***	To be filed in accordance with Section 310(a) of the Trust Indenture Act of 1939, as amended.	
 
ITEM 17.	Undertakings	
Each 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:
a. To include any prospectus required by section 10(a)(3) of the Securities Act of 1933 (the “Securities Act”);
b. To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
 
II-7

c. To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
Provided, however, that paragraphs 1(a), 1(b) and 1(c) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or 15(d) of the Exchange Act of 1934 (the “Exchange Act”) that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
2. That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
4. That, for the purpose of determining liability under the Securities Act to any purchaser:
a. Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
b. Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
5. That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this Registration Statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
a. Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
b. Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
c. The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
 
II-8

d. Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
6. That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
7. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
8. To file an application for the purpose of determining the eligibility of the trustee under the Subordinated Indenture to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939, as amended (the “Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

Exhibit 5.2
December 28, 2018
Concho Resources Inc.
600 W. Illinois Avenue
Midland, Texas 79701
 
Re:	Concho Resources Inc.	
 	Post-Effective Amendment No. 1 to Registration Statement on Form S-3	
Ladies and Gentlemen:
We have acted as counsel to Concho Resources Inc., a Delaware corporation (the “Company”) in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of the Registration Statement on Form S-3 (the “Initial Registration Statement”) filed on June 14, 2018, as amended by Post-Effective Amendment No. 1 to the Initial Registration Statement (“Amendment No. 1” and, together with the Initial Registration Statement, the “Registration Statement”), filed on the date hereof under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration under the Securities Act of guarantees (the “Guarantees”) of the Company’s unsecured debt securities, which may either be senior debt securities (the “Senior Debt Securities”) or subordinated debt securities (the “Subordinated Debt Securities” and, collectively with the Senior Debt Securities, the “Debt Securities”) by certain direct and indirect wholly owned subsidiaries of the Company listed as co-registrants thereto (the “Subsidiary Guarantors).
The Debt Securities and Guarantees are collectively referred to herein as the “Securities.” The Senior Debt Securities are to be issued under an indenture, dated as of September 18, 2009, between the Company, the subsidiary guarantors named therein and Wells Fargo Bank, National Association (the “Trust Company”), as trustee (the “Senior Base Indenture”), as amended and supplemented by the (i) Tenth Supplemental Indenture, dated as of December 28, 2016, (ii) Eleventh Supplemental Indenture, dated as of January 25, 2017, (iii) Twelfth Supplemental Indenture, dated as of September 26, 2017, (iv) Thirteenth Supplemental Indenture, dated as of September 26, 2017, (v) Fourteenth Supplemental Indenture, dated as of July 2, 2018, (vi) Fifteenth Supplemental Indenture, dated as of July 2, 2018, and (vii) Sixteenth Supplemental Indenture, dated as of August 14, 2018, among the Company, the guarantors party thereto and the Trust Company. The Subordinated Debt Securities are to be issued under an indenture to be entered into among the Company, the subsidiary guarantors named therein and a financial institution to be named at the time such indenture is executed, as trustee (the “Subordinated Base Indenture” and, together with the Senior Base Indenture, the “Base Indentures”).

In arriving at the opinions expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the Senior Base Indenture, a form of the Subordinated Base Indenture and such other documents, corporate records, certificates of officers of the Company, the Subsidiary Guarantors and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions. In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies. As to any facts material to these opinions, we have relied to the extent we deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company, the Subsidiary Guarantors and others.
We have assumed without independent investigation that:
(i) at the time any Securities are sold pursuant to the Registration Statement (the “Relevant Time”), the Registration Statement and any supplements and amendments thereto (including Amendment No. 1 and other post-effective amendments) will be effective and will comply with all applicable laws;
(ii) at the Relevant Time, a prospectus supplement will have been prepared and filed with the Commission describing the Securities offered thereby and all related documentation and will comply with all applicable laws;
(iii) all Securities will be issued and sold in the manner stated in the Registration Statement and the applicable prospectus supplement;
(iv) at the Relevant Time, all corporate or other action required to be taken by the Company or any Subsidiary Guarantor to duly authorize each proposed issuance of Securities and any related documentation (including the execution (in the case of certificated Securities), delivery and performance of the Securities and any related documentation referred to in paragraph 1 below) shall have been duly completed and shall remain in full force and effect;
(v) in the case of Debt Securities and Guarantees, at the Relevant Time, the Senior Base Indenture shall have been duly qualified under the Trust Indenture Act of 1939, as amended (the “TIA”), and, with respect to the Subordinated Debt Securities, the Subordinated Base Indenture shall have been duly executed and delivered by the Company and all other parties thereto and duly qualified under the TIA; and
(vi) at the Relevant Time, a definitive purchase, underwriting or similar agreement and any other necessary agreement with respect to any Securities offered or issued will have been duly authorized by all necessary corporate or other action of the Company and each Subsidiary Guarantor and duly executed and delivered by the Company, each Subsidiary Guarantor and the other parties thereto.
 
2

Based on the foregoing and in reliance thereon, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that:
1.    With respect to the Guarantees, when:
a.    the terms and conditions of such Guarantees have been duly established by supplemental indenture or officers’ certificate in accordance with the terms and conditions of the Base Indentures,
b.    any such supplemental indenture has been duly executed and delivered by the Company, the Subsidiary Guarantors and the trustee (the Base Indentures, together with any such supplemental indenture or any officers’ certificate described in clause (a) above, the “Indentures”), and
c.    such Debt Securities have been executed (in the case of certificated Debt Securities), delivered and authenticated in accordance with the terms of the Indentures and issued and sold for the consideration set forth in the applicable definitive purchase, underwriting or similar agreement,
the Guarantees will be legal, valid and binding obligations of the Subsidiary Guarantors obligated thereon, enforceable against such Subsidiary Guarantors in accordance with their respective terms.
The opinions expressed above are subject to the following exceptions, qualifications, limitations and assumptions:
A.    We render no opinion herein as to matters involving the laws of any jurisdiction other than the State of New York and the United States of America. This opinion is limited to the effect of the current state of the laws of the State of New York and the United States of America and the facts as they currently exist. We assume no obligation to revise or supplement this opinion in the event of future changes in such laws or the interpretations thereof or such facts.
B.    The opinions above with respect to the Indentures and the Guarantees are subject to (i) the effect of any bankruptcy, insolvency, reorganization, moratorium, arrangement or similar laws affecting the rights and remedies of creditors generally, including without limitation the effect of statutory or other laws regarding fraudulent transfers or preferential transfers, and (ii) general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies regardless of whether enforceability is considered in a proceeding in equity or at law.
 
3

C.    We express no opinion regarding the effectiveness of (i) any waiver of stay, extension or usury laws, (ii) provisions relating to indemnification, exculpation or contribution, to the extent such provisions may be held unenforceable as contrary to public policy or federal or state securities laws or due to the negligence or willful misconduct of the indemnified party, (iii) any purported fraudulent transfer “savings” clause, (iv) any waiver of the right to jury trial or (v) any provision to the effect that every right or remedy is cumulative and may be exercised in addition to any other right or remedy or that the election of some particular remedy does not preclude recourse to one or more others.
You have informed us that you intend to issue Securities from time to time on a delayed or continuous basis, and we understand that prior to issuing any Securities pursuant to the Registration Statement (i) you will advise us in writing of the terms thereof, and (ii) you will afford us an opportunity to (x) review the operative documents pursuant to which such Securities are to be issued or sold (including the applicable offering documents), and (y) file such supplement or amendment to this opinion (if any) as we may reasonably consider necessary or appropriate.
We consent to the filing of this opinion as an exhibit to the Registration Statement, and we further consent to the use of our name under the caption “Legal Matters” in the Registration Statement and the prospectus that forms a part thereof. In giving these consents, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.
Very truly yours,
/s/ Gibson, Dunn & Crutcher LLP
