23

(h)           At the time of execution of this Agreement, the Initial Purchaser shall have received from NSAI an initial letter (the “initial expert letter”), in form and substance satisfactory to the Initial Purchaser, addressed to the Initial Purchaser and dated the date hereof and a subsequent letter dated as of the Closing Date, which such letter shall cover the period from any initial expert letter to the Closing Date, stating the conclusions and findings of such firm with respect to the reserve and other operational information and other matters as is customary to initial purchasers in connection with similar transactions.

(iii)          To the effect of Section 7(g) (provided that no representation with respect to the judgment of Goldman need be made) and Section 7(j).

(j)            Subsequent to the earlier of the Applicable Time and the execution and delivery of this Agreement there shall not have occurred any of the following: (i) downgrading shall have occurred in the rating accorded the Company’s debt securities by any “nationally recognized statistical rating organization,” as that term is used by the Commission in Section 15E under the Exchange Act, or (ii) such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities.

(k)           The Notes shall be eligible for clearance and settlement through DTC.

(n)           On or prior to the Closing Date, the Company and the Guarantor shall have furnished to the Initial Purchaser such further certificates and documents as the Initial Purchaser may reasonably request.

8.             Indemnification and Contribution.

(a)           The Company and the Guarantor, hereby agree, jointly and severally, to indemnify and hold harmless the Initial Purchaser, its affiliates, directors, officers and employees and each person, if any, who controls the Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which that Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by the Company or the Guarantor (or based upon any written information furnished by the Company or the Guarantor) specifically for the purpose of qualifying any or all of the

25

Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), or (C) in any materials or information provided to investors by, or with the approval of, the Company or the Guarantor in connection with the marketing of the offering of the Notes (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically), or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse the Initial Purchaser and each such affiliate, director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Initial Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company and the Guarantor shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Offering Memorandum, the Pricing Disclosure Package or Offering Memorandum, or in any such amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company by the Initial Purchaser specifically for inclusion therein, which information consists solely of the information specified in Section 8(e).  The foregoing indemnity agreement is in addition to any liability that the Company or the Guarantor may otherwise have to the Initial Purchaser or to any affiliate, director, officer, employee or controlling person of the Initial Purchaser.

(b)           The Initial Purchaser hereby agrees to indemnify and hold harmless the Company, the Guarantor, their respective officers and employees, each of their respective directors, and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, the Guarantor or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky Application, or (C) in any Marketing Materials, or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company by the Initial Purchaser specifically for inclusion therein, which information is limited to the information set

26

forth in Section 8(e).  The foregoing indemnity agreement is in addition to any liability that the Initial Purchaser may otherwise have to the Company, the Guarantor or any such director, officer, employee or controlling person.

(c)           Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under paragraphs (a) or (b) above except to the extent it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under paragraphs (a) or (b) above.  If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Initial Purchaser shall have the right to employ counsel to represent the Initial Purchaser and its respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Initial Purchaser against the Company or the Guarantor under this Section 8, if (i) the Company, the Guarantor and the Initial Purchaser shall have so mutually agreed; (ii) the Company and the Guarantor have failed within a reasonable time to retain counsel reasonably satisfactory to the Initial Purchaser; (iii) the Initial Purchaser and its respective directors, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the Company and the Guarantor; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Initial Purchaser or its respective directors, officers, employees or controlling persons, on the one hand, and the Company and the Guarantor, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Company and the Guarantor and the Company and the Guarantor shall no longer have the right to assume the defense of any such claim or action.  No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be

27

unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any 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 Section 8(a) or (b) hereof, 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 60 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 or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d)           If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Guarantor, on the one hand, and the Initial Purchaser, on the other, from the offering of the Notes, or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the Company and the Guarantor, on the one hand, and the Initial Purchaser, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations.  The relative benefits received by the Company and the Guarantor, on the one hand, and the Initial Purchaser, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Company and the Guarantor, on the one hand, and the total discounts and commissions received by the Initial Purchaser with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement as set forth on the cover page of the Offering Memorandum.  The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, the Guarantor, or the Initial Purchaser, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission.  For purposes of the preceding two sentences, the net proceeds deemed to be received by the Company shall be deemed to be also for the benefit of the Guarantor, and information supplied by the Company shall also be deemed to have been supplied by the Guarantor.  The Company, the Guarantor, and the Initial Purchaser agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Initial Purchaser was treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein.  The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or

28

defending any such action or claim.  Notwithstanding the provisions of this Section 8(d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale to Eligible Purchasers of the Notes initially purchased by it exceeds the amount of any damages that such Initial Purchaser has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission.  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.

(e)           The Initial Purchaser confirms and the Company and the Guarantor acknowledge and agree that the statements with respect to the offering of the Notes by the Initial Purchaser set forth in the paragraphs set forth in “Plan of Distribution—Over-Allotment and Stabilizing and Syndicate Covering Transactions” in the Pricing Disclosure Package and the Offering Memorandum are correct and constitute the only information concerning such Initial Purchaser furnished in writing to the Company or the Guarantor by the Initial Purchaser specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum or in any amendment or supplement thereto or in any Blue Sky Application or in any Marketing Materials.

9.             Reimbursement of Initial Purchaser’s Expenses.  If (a) the Company for any reason fails to tender the Notes for delivery to the Initial Purchaser, or (b) the Initial Purchaser declines to purchase the Notes for any reason permitted under this Agreement, the Company and the Guarantor shall reimburse the Initial Purchaser for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Initial Purchaser) incurred by the Initial Purchaser in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Company and the Guarantor shall pay the full amount thereof to the Initial Purchaser.

10.          Notices, etc.  All statements, requests, notices and agreements hereunder shall be in writing, and:

(a)           if to the Initial Purchaser, shall be delivered or sent by hand delivery, mail, overnight courier or facsimile transmission to Goldman, Sachs & Co., 200 West Street, New York, New York  10282, Attention:  Registration Department;

(b)           if to the Company or the Guarantor, shall be delivered or sent by mail, telex, overnight courier or facsimile transmission to RSP Permian, Inc., 3141 Hood Street, Suite 500, Dallas, Texas, 75219, Attention: James E.

29

respective successors.  This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that the representations, warranties, indemnities and agreements of the Company and the Guarantor contained in this Agreement shall also be deemed to be for the benefit of affiliates, directors, officers and employees of the Initial Purchaser and each person or persons, if any, controlling the Initial Purchaser within the meaning of Section 15 of the Securities Act.  Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 13, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

12.          Survival.  The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantor and the Initial Purchaser contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Notes and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them.

13.          Definition of the Terms “Business Day”, “Affiliate”, and “Subsidiary.” For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange, Inc. is open for trading, and (b) “affiliate” and “subsidiary” have the meanings set forth in Rule 405 under the Securities Act.

14.          Governing Law & Venue.  This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York.  The Company, the Guarantor and the Initial Purchaser agree that any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State or U.S. federal court in The City of New York and County of New York, and waives any objection that such party may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the exclusive jurisdiction of such courts in any suit, action or proceeding.

15.          Waiver of Jury Trial.  Each of the Company and the Initial Purchaser 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.

16.          No Fiduciary Duty.  The Company and the Guarantor acknowledge and agree that in connection with this offering, or any other services the Initial Purchaser may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Initial Purchaser: (a) no fiduciary or agency relationship between the Company, the Guarantor and any other person, on the one hand, and the Initial Purchaser, on the other, exists; (b) the Initial Purchaser is not acting as advisors, expert or otherwise, to the Company or the Guarantor, including, without limitation, with respect to the determination of the purchase price of the Notes, and such relationship between the Company and the Guarantor, on the one hand, and the Initial Purchaser, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Initial Purchaser may have to the Company and the Guarantor shall be limited to those duties and obligations specifically stated herein; (d)

30

the Initial Purchaser and its respective affiliates may have interests that differ from those of the Company and the Guarantor; and (e) the Company and the Guarantor have consulted their own legal and financial advisors to the extent they deemed appropriate.  The Company and the Guarantor hereby waive any claims that the Company and the Guarantor may have against the Initial Purchaser with respect to any breach of fiduciary duty in connection with the Notes.
