V.     Reaffirmation of Representations and Warranties.  To induce the Combined
Lenders and the Global Administrative Agent to enter into this Amendment, the
U.S. Borrower and the Canadian Borrower hereby reaffirm, as of the date hereof,
the following:
 
(i)     The representations and warranties of each Loan Party (as such term is
defined in the U.S. Credit Agreement and the Canadian Credit Agreement,
collectively, the “Combined Loan Parties”) set forth in the Combined Loan
Documents to which it is a party are true and correct on and as of the date
hereof (or, if stated to have been made expressly as of an earlier date, were
true and correct in all material respects as of such date and, except to the
extent waived in writing by the Combined Lenders, the Required Lenders, the
Majority Lenders, the U.S. Lenders or the U.S. Required Lenders, as applicable).
 
(ii)    Each of the Combined Loan Parties (a) is a corporation or limited
partnership duly incorporated or organized (as applicable), validly existing and
in good standing under the laws of its jurisdiction of incorporation or
organization, (b) has all corporate or limited partnership power (as applicable)
and all material governmental licenses, authorizations, consents and approvals
required to carry on its businesses as now conducted and as proposed to be
conducted, and (c) is duly qualified to transact business as a foreign
corporation or limited partnership in each jurisdiction where a failure to be so
qualified would reasonably be expected to have a Material Adverse Effect.
 
(iii)   The execution, delivery and performance of this Amendment and the other
Combined Loan Documents by each Combined Loan Party (to the extent each Combined
Loan Party is a party to this Amendment and such Combined Loan Documents) (a)
are within such Combined Loan Party’s corporate or limited partnership powers,
(b) when executed will be duly authorized by all necessary corporate or limited
partnership action, (c) require no action by or in respect of, or filing with,
any Governmental Authority (other than (1) actions or filings pursuant to the
Exchange Act and (2) actions or filings that have been taken or made and are in
full force and effect) and (d) do not contravene, or constitute a default under,
any provision of applicable Governmental Rule (including, without limitation,
Regulation U) or of the articles or certificate of incorporation, bylaws,
regulations, partnership agreement or comparable charter documents of any
Combined Loan Party or of any agreement, judgment, injunction, order, decree or
other instrument binding upon any Combined Loan Party or result in the creation
or imposition of any Lien on any Borrowing Base Property or Collateral other
than the Liens securing the Combined Obligations.
 
(iv)   This Amendment and each other Combined Loan Document constitutes, or when
executed and delivered will constitute, valid and binding obligations of each
Combined Loan Party which is a party thereto, enforceable against each such
Combined Loan Party which executes the same in accordance with its terms except
as the enforceability thereof may be limited by (a) bankruptcy, insolvency,
reorganization, moratorium, or similar Governmental Rules affecting creditors’
rights generally, and (b) equitable principles of general applicability (whether
enforcement is sought by proceedings at law or in equity).
 
(v)    Neither a Default nor an Event of Default has occurred and will exist
under either Combined Credit Agreement after giving effect to the transactions
contemplated by this Amendment or the other Combined Loan Documents, after
giving effect to the amendments and consents contained herein.  Neither the U.S.
Borrower or any of its Subsidiaries nor the Canadian Borrower or any of its
Subsidiaries is in default under, nor has any event or circumstance occurred
which, but for the expiration of any applicable grace period or the giving of
notice, or both, would constitute a default under, any Material Agreement to
which the U.S. Borrower or any of its Subsidiaries or the Canadian Borrower or
any of its Subsidiaries is a party or by which the U.S. Borrower or any of its
Subsidiaries or the Canadian Borrower or any of its Subsidiaries is bound which
default would reasonably be expected to have a Material Adverse Effect.  The
U.S. Borrower is in compliance with the financial covenants set forth in Article
VI of the U.S. Credit Agreement.
 
(vi)   No event or events have occurred since December 31, 2009 which
individually or in the aggregate would reasonably be expected to have a Material
Adverse Effect.
 
VI.     Defined Terms.  Capitalized terms used herein when defined in the U.S.
Credit Agreement shall have the same meanings herein unless the context
otherwise requires.
 
VII.    Reaffirmation of Combined Credit Agreements.  This Amendment shall be
deemed to be an amendment to the Combined Credit Agreements, and the Combined
Credit Agreements, as amended hereby, and the other Combined Loan Documents are
hereby ratified, approved and confirmed in each and every respect.  All
references to the Combined Credit Agreements herein and in any other document,
instrument, agreement or writing shall hereafter be deemed to refer to the
Combined Credit Agreements as amended hereby.
 
VIII.  Governing Law.  THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF TEXAS.
 
NOTWITHSTANDING THE FOREGOING SENTENCE AND AFTER GIVING EFFECT TO THE TEXTUAL
AMENDMENTS CONTAINED IN SECTIONS I AND II OF THIS AMENDMENT, (i) THE U.S. CREDIT
AGREEMENT (AS AMENDED HEREBY) SHALL CONTINUE TO BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW SPECIFIED IN SECTION 10.9(a) OF THE U.S. CREDIT
AGREEMENT, AND (ii) THE CANADIAN CREDIT AGREEMENT SHALL CONTINUE TO BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW SPECIFIED IN SECTION 10.9(a) OF
THE CANADIAN CREDIT AGREEMENT.
 
IX.   Severability of Provisions.  Any provision of this Amendment held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.
 
X.    Counterparts.  This Amendment may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract.  Delivery of an executed counterpart of a signature page of
this Amendment by telecopy (or other electronic transmission acceptable to the
Global Administrative Agent) shall be effective as delivery of a manually
executed counterpart of this Amendment.
 
XI.   Headings.  Article and Section headings used herein are for convenience of
reference only, are not part of this Amendment and shall not affect the
construction of, or be taken into consideration in interpreting, this Amendment.
 
XII.  Successors and Assigns.  This Amendment shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby (including any Affiliate of an Issuing Bank that issues any
Letter of Credit), except that neither the U.S. Borrower nor the Canadian
Borrower may assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of the Global Administrative Agent,
each Issuing Bank and each Combined Lender (and any attempted assignment or
transfer by either the U.S. Borrower or the Canadian Borrower without such
consent shall be null and void).  Nothing in this Amendment, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, and their respective successors and assigns permitted hereby) any legal
or equitable right, remedy or claim under or by reason of this Amendment.
 
XIII. No Oral Agreements.  THIS AMENDMENT, THE COMBINED CREDIT AGREEMENTS, AS
AMENDED HEREBY, AND THE OTHER COMBINED LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT BETWEEN AND AMONG THE PARTIES WITH RESPECT TO THE SUBJECT MATTER
HEREOF AND THEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.
 
XIV. Loan Document.  This Amendment constitutes a “Loan Document,” a “Canadian
Loan Document” and a “Combined Loan Document” under and as defined in the U.S.
Credit Agreement, and a “Loan Document,” a “U.S. Loan Document” and a “Combined
Loan Document” under and as defined in the Canadian Credit Agreement.
