THIS EIGHTH AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT (this
“Amendment”) dated as of April 12, 2012, is by and among Concho Resources Inc.,
a Delaware corporation (the “Borrower”), the Lenders party hereto (the
“Lenders”) and JPMorgan Chase Bank, N.A., as Administrative Agent (in such
capacity, the “Administrative Agent”). Unless the context otherwise requires or
unless otherwise expressly defined herein, capitalized terms used but not
defined in this Amendment have the meanings assigned to such terms in the Credit
Agreement (as defined below).

WITNESSETH:

WHEREAS, the Borrower, the Administrative Agent and the Lenders entered into
that certain Amended and Restated Credit Agreement dated as of July 31, 2008 (as
amended, amended and restated, supplemented or otherwise modified from time to
time, the “Credit Agreement”); and

WHEREAS, the Borrower has requested that the Administrative Agent and the
Required Lenders amend the Credit Agreement in certain respects.

NOW, THEREFORE, for and in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged and confessed, the Borrower, the
Administrative Agent and the Required Lenders hereby agree as follows:

SECTION 1. Amendments to Credit Agreement. Subject to the satisfaction or waiver
in writing of each condition precedent set forth in Section 3, and in reliance
on the representations, warranties, covenants and agreements contained in this
Amendment, the Credit Agreement shall be amended in the manner provided in this
Section 1.

1.1 Senior Notes Adjustment. Section 3.05 of the Credit Agreement shall be and
it hereby is amended in its entirety to read as follows:

3.05 Senior Notes Adjustment. Unless otherwise waived in writing by the Required
Lenders, upon the incurrence of any Indebtedness under any Senior Notes
permitted under Section 7.03(f) at any time and from time to time on and after
May 1, 2013, the Borrowing Base and the Conforming Borrowing Base then in effect
shall each be reduced by the lesser of (i) $300 for every $1,000 in stated
amount of such Indebtedness as of the date such Indebtedness is incurred and
(ii) such other amount, if any, determined by the Required Lenders in their sole
discretion prior to issuance of such Senior Notes; provided that no such
adjustment shall be required with respect to any Permitted Refinancing of any
such Senior Notes. For the avoidance of doubt, the stated amount of such
Indebtedness that constitutes Permitted Refinancings of existing Senior Notes
shall not be included for purposes of determining the reduction in the Borrowing
Base and the Conforming Borrowing Base required by this Section 3.05 and only
the stated amount in excess of such Permitted Refinancings shall be included in
calculating the adjustment required by this Section 3.05.

1.2 Indebtedness Under Senior Notes. Section 7.03(f) of the Credit Agreement

(f) subject to any adjustment to the Borrowing Base and Conforming Borrowing
Base required under Section 3.05, unsecured Indebtedness of the Borrower
evidenced by unsecured senior notes (other than the Marbob Seller Note) or
unsecured senior subordinated notes and Guarantees thereof in an aggregate
principal amount not to exceed $3,100,000,000 at any time outstanding (“Senior
Notes”) and any Permitted Refinancing of any Indebtedness incurred under this
clause (f); provided that (i) at the time of and immediately after giving effect
to each issuance of such Senior Notes or any Permitted Refinancing thereof, no
Default shall have occurred and be continuing, (ii) the final stated maturity
date of such Senior Notes is not earlier than the first anniversary after the
Maturity Date (as in effect on the date of issuance of such Senior Notes),
(iii) the non-default stated interest rate of such Senior Notes shall be
consistent with market terms for issuers of similar size and credit quality at
the time of issuance, (iv) no scheduled principal amortization is required under
such Senior Notes prior to the stated maturity of such Senior Notes and (v) such
Senior Notes are evidenced by an indenture and related documents containing
terms and conditions, covenants and events of default that are customary for
similar notes and that are, in each case, reasonably satisfactory to the
Administrative Agent; and

SECTION 2. Reaffirmation of Borrowing Base. This Amendment shall constitute a
notice of reaffirmation of the Borrowing Base pursuant to Section 3.04 of the
Credit Agreement and the Administrative Agent hereby notifies the Borrower that,
as of the date of this Amendment, the Borrowing Base shall continue to be
$2,500,000,000 until the earlier of (a) next Redetermination of the Borrowing
Base pursuant to Article III of the Credit Agreement and (b) the date the
Borrowing Base is otherwise adjusted pursuant to the terms of the Credit
Agreement. The Borrower and the Required Lenders agree that the reaffirmation of
the Borrowing Base provided for in this Section 2 shall be considered and deemed
to be the April 1, 2012 Scheduled Redetermination.

and correct in all respects).

amended and modified hereby, remain in full force and effect. The Borrower
hereby agrees that the amendments and modifications herein contained shall not
impair its liabilities, duties and obligations under the Credit Agreement and
the other Loan Documents to which it is a party or the Liens granted by it
securing the payment and performance thereof. The execution, delivery and

power or remedy of any Lender, the L/C Issuer or the Administrative Agent under

by different parties hereto in separate counterparts each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document. However, this Amendment shall bind no party until the Borrower, the
Required Lenders, and the Administrative Agent have executed a counterpart.

electronic mail shall be effective as delivery of manually executed counterparts
