Acquisition Information so disclosed; (v) if authorized by QRM; and (vi) to the extent such
Acquisition Information becomes publicly available other than through a breach by the General
Partner of its obligation arising under Section 6.2(a).

          (c) Remedies and Enforcement. The General Partner acknowledges and agrees that a
breach by it of its obligations under this Article VI would cause irreparable harm to QRM
and that monetary damages would not be adequate to compensate QRM. Accordingly, the General
Partner agrees that QRM shall be entitled to immediate equitable relief, including a

-12-

 

temporary or permanent injunction, to prevent any threatened, likely or ongoing violation by
the General Partner, without the necessity of posting bond or other security. QRM’s right to
equitable relief shall be in addition to other rights and remedies available to QRM, for monetary
damages or otherwise.

     6.3 Survival. The provisions of this Article VI shall survive the termination
of this Agreement.

continuing at the time notice of termination is delivered to the General Partner; or

          (c) This Agreement may be terminated at any time by the General Partner upon QRM’s material

AUDIT RIGHTS

     At any time during the Term and for one year thereafter, the General Partner shall have the

affected thereby and shall be enforced to the greatest extent permitted by law.

the same effect as if all signatory Parties had signed the same document. All counterparts shall
be construed together and shall constitute one and the same instrument.

     9.13 Withholding or Granting of Consent. Except as expressly provided to the contrary
in this Agreement, each Party may, with respect to any consent or approval that it is entitled to
grant pursuant to this Agreement, grant or withhold such consent or approval in its sole and
uncontrolled discretion, with or without cause, and subject to such conditions as it shall deem
appropriate.

if the effect thereof would be to cause such Party to be in violation of any applicable law,
statute, rule or regulation.

The Credits

     Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each
Lender agrees to make Loans to the Borrower during the Availability Period in an aggregate
principal amount that will not result in such Lender’s Revolving Credit Exposure exceeding such
Lender’s Commitment or the total Revolving Credit Exposures exceeding the total Commitments.
Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower
may borrow, repay and reborrow the Loans.

     Section 2.02 Loans and Borrowings.

          (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing
consisting of Loans made by the Lenders ratably in accordance with their respective Commitments.
The failure of any Lender to make any Loan required to be made by it shall not relieve any other
Lender of its obligations hereunder; provided that the Commitments are several and no
Lender shall be responsible for any other Lender’s failure to make Loans as required.

          (b) Types of Loans. Subject to Section 3.03, each Borrowing shall be
comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance
herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or
foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of
such option shall not affect the obligation of the Borrower to repay such Loan in accordance with
the terms of this Agreement.

          (c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each
Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that
is an integral multiple of $500,000 and not less than $1,000,000. At the time that each ABR
Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of
$250,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an
aggregate amount that is equal to the entire unused balance of the total Commitments or that is
required to finance the reimbursement of an LC Disbursement as contemplated by Section
2.08(e). Borrowings of more than one Type may be outstanding at the same time,
provided that there shall not at any time be more than a total of ten (10) Eurodollar
Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall
not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest
Period requested with respect thereto would end after the Maturity Date.

25

 

          (d) Notes. Upon request of such Lender, the Loans made by a Lender shall be evidenced
by a single promissory note of the Borrower in substantially the form of Exhibit A, dated,
in the case of (i) any Lender party hereto as of the date of this Agreement or (ii) any Lender
that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of
the Assignment and Assumption, payable to such Lender in a principal amount equal to its Maximum
Credit Amount as in effect on such date, and otherwise duly completed. In the event that any
Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to
Section 2.06, Section 12.04(b) or otherwise), the Borrower shall, upon request of
such Lender, deliver or cause to be delivered on the effective date of such increase or decrease, a
new Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after
giving effect to such increase or decrease, and otherwise duly completed and such Lender shall
promptly return to the Borrower the previously issued Note held by such Lender. The date, amount,
Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all
payments made on account of the principal thereof, shall be recorded by such Lender on its books
for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to
such Note or any continuation thereof or on any separate record maintained by such Lender. Failure
to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s
rights or obligations in respect of such Loans or affect the validity of such transfer by any
Lender of its Note.

     Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall
notify the Administrative Agent of such request by telephone in the case of a Eurodollar
Borrowing, not later than 12:00 noon, New York City time, three (3) Business Days before the date
of the proposed Borrowing or in the case of an ABR Borrowing, not later than 12:00 noon, New York
City time, on the Business Day of the proposed Borrowing; provided that no such notice
shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC
Disbursement as provided in Section 2.08(e). Each such telephonic Borrowing Request shall
be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative
Agent of a written Borrowing Request in substantially the form of Exhibit B and signed by
the Borrower. Each such telephonic and written Borrowing Request shall specify the following
information in compliance with Section 2.02:

               (i) the aggregate amount of the requested Borrowing;

               (ii) the date of such Borrowing, which shall be a Business Day;

               (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

Period”;

Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit
Exposures (giving effect to the requested Borrowing); and

26

 

               (vi) the location and number of the Borrower’s account to which funds are to be disbursed,
which shall comply with the requirements of Section 2.05(a).

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an
ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar
Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s
duration. Each Borrowing Request shall constitute a representation that the amount of the
requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total
Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective
Borrowing Base).

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the
Administrative Agent shall advise each Lender of the details thereof and of the amount of such
Lender’s Loan to be made as part of the requested Borrowing.

     Section 2.04 Interest Elections.

          (a) Conversion and Continuance. Each Borrowing initially shall be of the Type
specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower
may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the
case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this
Section 2.04. The Borrower may elect different options with respect to different portions
of the affected Borrowing, in which case each such portion shall be allocated ratably among the
Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion
shall be considered a separate Borrowing.

          (b) Interest Election Requests. To make an election pursuant to this Section
2.04, the Borrower shall notify the Administrative Agent of such election by telephone by the
time that a Borrowing Request would be required under Section 2.03 if the Borrower were
requesting a Borrowing of the Type resulting from such election to be made on the effective date of
such election. Each such telephonic Interest Election Request shall be irrevocable and shall be
confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest
Election Request in substantially the form of Exhibit C and signed by the Borrower.

          (c) Information in Interest Election Requests. Each telephonic and written Interest
Election Request shall specify the following information:

               (i) the Borrowing to which such Interest Election Request applies and, if different options
are being elected with respect to different portions thereof, the portions thereof to be allocated
to each resulting Borrowing (in which case the information to be specified pursuant to Section
2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing);

               (ii) the effective date of the election made pursuant to such Interest Election Request,
which shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;
and

27

 

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period contemplated by
the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one
month’s duration.

          (d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an
Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing.

          (e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default on
Interest Election. If the Borrower fails to deliver a timely Interest Election Request with
respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then,
unless such Borrowing is repaid as provided herein, at the end of such Interest Period such
Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof,
if an Event of Default has occurred and is continuing: no outstanding Borrowing may be converted
to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the
conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall
be ineffective) and unless repaid, each Eurodollar Borrowing shall be converted to an ABR
Borrowing at the end of the Interest Period applicable thereto.

     Section 2.05 Funding of Borrowings.

          (a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder
on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m., New York
City time, to the account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the
Borrower by promptly crediting the amounts so received, in like funds, to the account of the
Borrower designated by the Borrower in the applicable Borrowing Request; provided that ABR
Loans made to finance the reimbursement of an LC Disbursement as provided in Section
2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. Nothing herein
shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or
manner or to constitute a representation by any Lender that it has obtained or will obtain the
funds for its Loan in any particular place or manner.

          (b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender’s share of such Borrowing, the
Administrative Agent may assume that such Lender has made such share available on such date in
accordance with Section 2.05(a) and may, in reliance upon such assumption, make available
to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and
the Borrower severally agree to pay to the Administrative Agent forthwith on demand such
corresponding amount with interest thereon, for each day from and including the date such amount is
made available to the Borrower to but excluding the date of

28

 

payment to the Administrative Agent, at in the case of such Lender, the greater of the
Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with
banking industry rules on interbank compensation or in the case of the Borrower, the interest rate
applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such
amount shall constitute such Lender’s Loan included in such Borrowing.

     Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts.

          (a) Scheduled Termination of Commitments. Unless previously terminated, the
Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit
Amounts or the Borrowing Base is terminated or reduced to zero, then the Commitments shall
terminate on the effective date of such termination or reduction.

          (b) Optional Termination and Reduction of Aggregate Credit Amounts.

               (i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate
Maximum Credit Amounts; provided that each reduction of the Aggregate Maximum Credit
Amounts shall be in an amount that is an integral multiple of $1,000,000 and not less than
$10,000,000 and the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts
if, after giving effect to any concurrent prepayment of the Loans in accordance with Section
3.04(c), the total Revolving Credit Exposures would exceed the total Commitments.

               (ii) The Borrower shall notify the Administrative Agent of any election to terminate or
reduce the Aggregate Maximum Credit Amounts under Section 2.06(b)(i) at least three (3)
Business Days prior to the effective date of such termination or reduction, specifying such
election and the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by
the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable. Any termination
or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be reinstated.
Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in
accordance with each Lender’s Applicable Percentage.

     Section 2.07 Borrowing Base.

          (a) Initial Borrowing Base. For the period from and including the Effective Date to
but excluding the first Redetermination Date to occur after such date, the amount of the Borrowing
Base shall be $300,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to
further adjustments from time to time pursuant to Section 2.07(e), Section 8.13(c),
Section 9.02(h) or Section 9.12(d).

          (b) Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined
semi-annually in accordance with this Section 2.07 (a “Scheduled Redetermination”),
and, subject to Section 2.07(d), such redetermined Borrowing Base shall become effective
and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders on May 1
and November 1 of each year, commencing May 1, 2011. In addition, the Borrower may, by notifying
the Administrative Agent thereof, and the Administrative Agent may, at the direction of the
Required Lenders, by notifying the Borrower thereof, one time

29

 

during any six (6) month period, each elect to cause the Borrowing Base to be redetermined
between Scheduled Redeterminations, and the Borrower may elect, by notifying the Administrative
Agent of any acquisition of Oil and Gas Properties with a purchase price in excess of the lesser of
$50,000,000 and a dollar amount equal to ten percent (10%) of the Borrowing Base, to cause the
Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim
Redetermination”) in accordance with this Section 2.07.

          (c) Scheduled and Interim Redetermination Procedure.

               (i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as
follows: Upon receipt by the Administrative Agent of (A) the Reserve Report and the certificate
required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled

Interim Redetermination, pursuant to Sections 8.12(b) and (c), and (B) such other
reports, data and supplemental information, including, without limitation, the information
provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested
by the Required Lenders (the Reserve Report, such certificate and such other reports, data and
supplemental information being the “Engineering Reports”), the Administrative Agent shall
evaluate the information contained in the Engineering Reports and shall, in its sole discretion,
propose a new Borrowing Base (the “Proposed Borrowing Base”), based upon such information
and such other information (including, without limitation, the status of title information with
respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of
any other Debt) as the Administrative Agent deems appropriate and consistent with its normal oil
and gas lending criteria as it exists at the particular time. In no event shall the Lenders
include Oil and Gas Properties located in jurisdictions other than the United States and Canada in
the Proposed Borrowing Base.

               (ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed
Borrowing Base (the “Proposed Borrowing Base Notice”):

          (A) in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have
received the Engineering Reports required to be delivered by the Borrower pursuant to Sections
8.12(a) and (c) in a timely and complete manner, then on or before April 15 and October
15 of such year following the date of delivery or (2) if the Administrative Agent shall not have
received the Engineering Reports required to be delivered by the Borrower pursuant to Sections
8.12(a) and (c) in a timely and complete manner, then promptly after the Administrative
Agent has received complete Engineering Reports from the Borrower and has had a reasonable
opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i);
and

          (B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15)
days after the Administrative Agent has received the required Engineering Reports.

               (iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must
be approved or deemed to have been approved by all of the Lenders as provided in this Section
2.07(c)(iii); and any Proposed Borrowing Base that would decrease or

30

 

maintain the Borrowing Base then in effect must be approved or be deemed to have been
approved by the Required Lenders as provided in this Section 2.07(c)(iii). Upon receipt
of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with the
Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate
Borrowing Base. If at the end of such fifteen (15) days, any Lender has not communicated its
approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be
an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, all of the
Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in
effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or
maintain the Borrowing Base then in effect, have approved or deemed to have approved, as
aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base effective on the
date specified in Section 2.07(d). If, however, at the end of such 15-day period, all of
the Lenders or the Required Lenders, as applicable, have not approved or deemed to have approved,
as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest
Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required
Lenders and, so long as such amount does not increase the Borrowing Base then in effect such
amount shall become the new Borrowing Base effective on the date specified in Section
2.07(d).

          (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing
Base is approved or is deemed to have been approved by all of the Lenders or the Required Lenders,
as applicable, pursuant to Section 2.07(c)(iii), or adjusted pursuant to Section
2.07(e), Section 8.13(c), Section 9.02(h) or Section 9.12(d), the
Administrative Agent shall notify the Borrower and the Lenders of the amount of the redetermined
Borrowing Base (the “New Borrowing Base Notice”), and such amount shall become the new
Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing
Bank and the Lenders:

               (i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have
received the Engineering Reports required to be delivered by the Borrower pursuant to Sections
8.12(a) and (c) in a timely and complete manner, then on May 1 or November 1, as
applicable, following such notice, or (B) if the Administrative Agent shall not have received the
Engineering Reports required to be delivered by the Borrower pursuant to Sections 8.12(a)
and (c) in a timely and complete manner, then on the Business Day next succeeding delivery
of such notice; and

               (ii) in the case of an Interim Redetermination or adjustment to the Borrowing Base under
Section 2.07(e), Section 8.13(c), Section 9.02(h) or Section
9.12(d), on the Business Day next succeeding delivery of such notice.

Such amount shall then become the Borrowing Base, as applicable, until the next Scheduled
Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing
Base under Section 2.07(e), Section 8.13(c), Section 9.02(h) or Section
9.12(d), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination,
Interim Redetermination or adjusted Borrowing Base shall become effective until the New Borrowing
Base Notice related thereto is received by the Borrower.

31

 

          (e) Reduction of Borrowing Base Upon Termination of Swap Agreements. If the
Borrower or any Subsidiary shall assign, terminate, unwind or create any off-setting positions in
respect of any hedge positions established pursuant to Swap Agreements upon which the Lenders
relied in determining the Borrowing Base and the net effect of such action (when taken together
with any other Swap Agreements executed contemporaneously with the taking of such action) would be
to reduce the economic value supporting the Borrowing Base, then the Borrowing Base shall be
simultaneously reduced by an amount (as reasonably determined by the Administrative Agent and
approved by the Required Lenders) equal to the economic value of such reduction.

     Section 2.08 Letters of Credit.

          (a) General. Subject to the terms and conditions set forth herein, the Borrower may
request the issuance of dollar denominated Letters of Credit for its own account or for the account
of any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the
Issuing Bank, at any time and from time to time during the Availability Period; provided
that the Borrower may not request the issuance, amendment, renewal or extension of Letters of
Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result
thereof. In the event of any inconsistency between the terms and conditions of this Agreement and
the terms and conditions of any Letter of Credit Agreement, the terms and conditions of this
Agreement shall control.

          (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter
of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication,
if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the
Administrative Agent (not less than three (3) Business Days in advance of the requested date of
issuance, amendment, renewal or extension) a notice:

               (i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be
amended, renewed or extended;

               (ii) specifying the date of issuance, amendment, renewal or extension (which shall be a
Business Day);

               (iii) specifying the date on which such Letter of Credit is to expire (which shall comply
with Section 2.08(c));

               (iv) specifying the amount of such Letter of Credit;

               (v) specifying the name and address of the beneficiary thereof and such other information as
shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

               (vi) specifying the amount of the then effective Borrowing Base and whether a Borrowing Base
Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to
the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding
Letter of Credit) and the pro forma total Revolving

32

 

Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment,
renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation that after giving effect to the requested issuance,
amendment, renewal or extension, as applicable, (i) the LC Exposure shall not exceed the LC
Commitment and (ii) the total Revolving Credit Exposures shall not exceed the total Commitments
(i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

If requested by the Issuing Bank in connection with the issuance or amendment of any Letter of
Credit, the Borrower also shall submit a Letter of Credit Application; provided that, in
the event of any conflict between such Letter of Credit Application and the terms of this
Agreement, the terms of this Agreement shall control.

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earlier of the date one (1) year after the date of the issuance of such Letter of
Credit (or, in the case of any renewal or extension thereof, one year after such renewal or
extension) and the date that is five Business Days prior to the Maturity Date.

          (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the
Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby
acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s
Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit.
In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank,
such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not
reimbursed by the Borrower on the date due as provided in Section 2.08(e), or of any
reimbursement payment required to be refunded to the Borrower for any reason. Each Lender
acknowledges and agrees that its obligation to acquire participations pursuant to this Section
2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected
by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of
Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency
or reduction or termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

          (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative
Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the
date that such LC Disbursement is made, if the Borrower shall have received notice of such LC
Disbursement prior to 10:00 a.m., New York City time, on such date, or if such notice has not been
received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York
City time, on the Business Day immediately following the day that the Borrower receives such
notice; provided that, unless the Borrower has notified the Administrative Agent that it
intends to reimburse all or part of such LC Disbursement without using Loan proceeds (and does
provide such reimbursement by the deadline set forth in the first sentence of this Section
2.08(e)) or has submitted a Borrowing Request with respect thereto (by

33

 

the deadline for reimbursement set forth in the first sentence of this Section
2.08(e)), if such LC Disbursement is not less than $1,000,000, the Borrower shall, subject to
the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does
hereby request under such circumstances, that such payment be financed with an ABR Borrowing in an
equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment
shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make
such payment when due, the Administrative Agent shall notify each Lender of the applicable LC
Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s
Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to
the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in
the same manner as provided in Section 2.05(a) with respect to Loans made by such Lender
(and Section 2.05(a) shall apply, mutatis mutandis, to the payment obligations of the
Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so
received by it from the Lenders. Promptly following receipt by the Administrative Agent of any
payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall
distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments
pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and
the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this
Section 2.08(e) to reimburse the Issuing Bank for any LC Disbursement (other than the
funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the
Borrower of its obligation to reimburse such LC Disbursement.

          (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as
provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of any lack of validity or enforceability of any Letter of Credit, any
Letter of Credit Agreement or this Agreement, or any term or provision therein, any draft or other
document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any
respect or any statement therein being untrue or inaccurate in any respect, payment by the Issuing
Bank under a Letter of Credit against presentation of a draft or other document that does not
comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or any other
event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but
for the provisions of this Section 2.08(f), constitute a legal or equitable discharge of,
or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the
Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have
any liability or responsibility by reason of or in connection with the issuance or transfer of any
Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to in the preceding sentence), or any error, omission, interruption,
loss or delay in transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a drawing thereunder),
any error in interpretation of technical terms or any consequence arising from causes beyond the
control of the Issuing Bank; provided that the foregoing shall not be construed to excuse
the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the Borrower to the extent
permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure
to exercise care when determining whether drafts and other documents presented under a Letter of
Credit comply with the terms thereof. The parties hereto

34

 

expressly agree that, in the absence of gross negligence or willful misconduct on the part of
the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank
shall be deemed to have exercised all requisite care in each such determination. In furtherance of
the foregoing and without limiting the generality thereof, the parties agree that, with respect to
documents presented which appear on their face to be in substantial compliance with the terms of a
Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon
such documents without responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such documents if such
documents are not in strict compliance with the terms of such Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of
Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by
telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made
or will make an LC Disbursement thereunder; provided that any failure to give or delay in
giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank
and the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until
the Borrower shall have reimbursed the Issuing Bank for such LC Disbursement (either with its own
funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest,
for each day from and including the date such LC Disbursement is made to but excluding the date
that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR
Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of the
Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant
to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of such Lender to
the extent of such payment.

          (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement
of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall
pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section
3.05(b). From and after the effective date of any such replacement, the successor Issuing
Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with
respect to Letters of Credit to be issued thereafter and references herein to the term
“Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank,
or to such successor and all previous Issuing Banks, as the context shall require. After the
replacement of the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto
and shall continue to have all the rights and obligations of the Issuing Bank under this Agreement
with respect to Letters of Credit issued by it prior to such replacement, but shall not be required
to issue additional Letters of Credit.

          (j) Cash Collateralization. If any Event of Default shall occur and be continuing
and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding
the deposit of cash collateral pursuant to this Section 2.08(j), or the Borrower is
required to pay to the Administrative Agent the excess attributable to an LC

35

 

Exposure in connection with any prepayment pursuant to Section 3.04(c), then the
Borrower shall deposit, in an account with the Administrative Agent, in the name of the
Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of
an Event of Default, the LC Exposure, and in the case of a payment required by Section
3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus
any accrued and unpaid interest thereon; provided that the obligation to deposit such cash
collateral shall become effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any Event of Default
described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to
the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first
priority and continuing perfected security interest in and Lien on such account and all cash,
checks, drafts, certificates and instruments, if any, from time to time deposited or held in such
account, all deposits or wire transfers made thereto, any and all investments purchased with funds
deposited in such account, all interest, dividends, cash, instruments, financial assets and other
Property from time to time received, receivable or otherwise payable in respect of, or in exchange
for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income
and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation
to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional,
without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down
all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent
permitted by applicable law, shall not be subject to any defense or be affected by a right of
set-off, counterclaim or recoupment which the Borrower or any other Obligor may now or hereafter
have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any
other Person for any reason whatsoever. Such deposit shall be held as collateral securing the
payment and performance of the Borrower’s and the other Obligors’ obligations under this Agreement
and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, over such account. Other than any interest earned on
the investment of such deposits, which investments shall be made at the option and sole discretion
of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear
interest. Interest or profits, if any, on such investments shall accumulate in such account.
Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank
for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall
be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure
at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other
obligations of the Borrower and the other Obligors under this Agreement or the other Loan
Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a
result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay
to the Administrative Agent the excess attributable to an LC Exposure in connection with any
prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as
aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default
have been cured or waived.

36

 

ARTICLE III

Payments of Principal and Interest; Prepayments; Fees

     Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay
to the Administrative Agent for the account of each Lender the then unpaid principal amount of each
Loan on the Termination Date.

     Section 3.02 Interest.

          (a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the
Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such Eurodollar Borrowing
plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (c) Post-Default Rate. Notwithstanding the foregoing, if any principal of or
interest on any Loan or any fee or other amount payable by the Borrower or any other Obligor
hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon
acceleration or otherwise, and including any payments in respect of a Borrowing Base Deficiency
under Section 3.04(c), then such overdue amount shall bear interest, after as well as
before judgment, at a rate per annum equal to in the case of overdue principal of any Loan, the
rate otherwise applicable to such Loan as provided in Section 3.02(a) or (b)
(including the Applicable Margin) plus an additional two percent (2%), but in no event to exceed
the Highest Lawful Rate and in the case of any other amount, the rate applicable to ABR Loans as
provided in Section 3.02(a) (including the Applicable Margin) plus an additional two
percent (2%), but in no event to exceed the Highest Lawful Rate and if an Event of Default has
occurred and is continuing, all Loans outstanding at such time shall bear interest, after as well
as before judgment, at the rate otherwise applicable to such Loan as provided in Section
3.02(a) or (b) (including the Applicable Margin) plus an additional two percent (2%), but in no
event to exceed the Highest Lawful Rate.

          (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan and on the Termination Date; provided that
interest accrued pursuant to Section 3.02(c) shall be payable on demand, in the event of
any repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior to
the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable
on the date of such repayment or prepayment, and in the event of any conversion of any Eurodollar
Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall
be payable on the effective date of such conversion.

          (e) Interest Rate Computations. All interest hereunder shall be computed on the basis
of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case
interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except
that interest computed by reference to the Alternate Base Rate at times when the Alternate Base
Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days
in a leap year), and in each case shall be payable for the actual number of days elapsed (including
the first day but excluding the last day). The applicable Alternate Base Rate,

37

 

Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

     Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest
Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO
Rate or the LIBO Rate for such Interest Period; or

          (b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or
LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost
to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest
Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent
notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer
exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made at the rate that is
the lower of (A) the Alternate Base Rate plus the Applicable Margin or (B) an alternate rate of
interest determined by the Majority Lenders as their cost of funds plus the Applicable Margin for
Eurodollar Borrowings.

     Section 3.04 Prepayments.

          (a) Optional Prepayments. Subject to Section 3.04(b), the Borrower shall have
the right at any time and from time to time to prepay any Borrowing in whole or in part.

          (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the
Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder in the case
of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three (3)
Business Days before the date of prepayment, or in the case of prepayment of an ABR Borrowing, not
later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be
irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or
portion thereof to be prepaid. Promptly following receipt of any such notice relating to a
Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial
prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance
of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a
Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments
shall be accompanied by accrued interest to the extent required by Section 3.02.

          (c) Mandatory Prepayments.

               (i) If, after giving effect to any termination or reduction of the Aggregate Maximum Credit
Amounts pursuant to Section 2.06(b), the total Revolving Credit

38

 

Exposures exceeds the total Commitments, then the Borrower shall prepay the Borrowings on
the date of such termination or reduction in an aggregate principal amount equal to such excess,
and if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure,
pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held
as cash collateral as provided in Section 2.08(j).

               (ii) Upon any redetermination of the Borrowing Base pursuant to Section 2.07(c)(iii)
or any adjustment to the amount of the Borrowing Base in accordance with Section 8.13(c),
if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then
the Borrower shall prepay the Borrowings in an aggregate principal amount equal to such excess,
and if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure,
pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held
as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to
make such prepayment and/or deposit of cash collateral either, at its election, (A) in one lump
sum payment on or before the date that is 30 days following the receipt by the Borrower of the New
Borrowing Base Notice in accordance with Section 2.07(d), or (B) in three (3) equal
payments, with each such payment being due on the date that is 30 days, 60 days, and 90 days,
respectively, following the date of receipt by the Borrower of the New Borrowing Base Notice in
accordance with Section 2.07(d); provided that all payments required to be made
pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date.
The Borrower shall notify the Administrative Agent in writing of its election in respect of
clauses (A) or (B) of the immediately preceding sentence within ten (10) days following the
receipt of the New Borrowing Base Notice in accordance with Section 2.07(d).

               (iii) Upon any adjustment to the amount of the Borrowing Base in accordance with Section
9.02(h) or Section 9.12(d), if the total Revolving Credit Exposures exceeds the
Borrowing Base as adjusted, then the Borrower shall prepay the Borrowings in an aggregate
principal amount equal to such excess, and if any excess remains after prepaying all of the
Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders
an amount equal to such excess to be held as cash collateral as provided in Section
2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash
collateral on the first (1st) Business Day after it receives the applicable New
Borrowing Base Notice in accordance with Section 2.07(d); provided that all
payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or
prior to the Termination Date.

               (iv) Upon any adjustment to the amount of the Borrowing Base in accordance with Section
2.07(e), if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then
the Borrower shall prepay the Borrowings in an aggregate principal amount equal to such excess,
and if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay
to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as
cash collateral as provided in Section 2.08(j). If the net proceeds received by QRE MLP
or its Subsidiaries from the unwinds or other actions described in Section 2.07(e) equals
or exceeds the prepayment or cash collateral amount required under this Section
3.04(c)(iv), then the Borrower shall be obligated to make such prepayment and/or deposit of
cash collateral in one lump sum payment on the first (1st) Business Day after it
receives the applicable New Borrowing Base Notice in accordance with

39

 

Section 2.07(d); however, if such net proceeds received by QRE MLP or its
Subsidiaries is less than the prepayment or cash collateral amount required under this Section
3.04(c)(iv), then the Borrower shall be obligated to make such prepayment and/or deposit of
cash collateral by (A) making a prepayment and/or cash collateral deposit in an amount equal to
all such net proceeds on the first (1st) Business Day after it receives the applicable
New Borrowing Base Notice in accordance with Section 2.07(d) and (B) then paying the
remainder of such required prepayment and/or cash collateral amount in three (3) equal payments,
with each such payment being due on the date that is 30 days, 60 days, and 90 days, respectively,
following the date of receipt by the Borrower of the New Borrowing Base Notice in accordance with
Section 2.07(d); provided that all payments required to be made pursuant to this
Section 3.04(c)(iv) must be made on or prior to the Termination Date.

               (v) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied,
first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings
then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such
Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least
number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar
Borrowing with the most number of days remaining in the Interest Period applicable thereto.

               (vi) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied
ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section
3.04(c) shall be accompanied by accrued interest to the extent required by Section
3.02.

          (d) No Premium or Penalty. Prepayments permitted or required under this Section
3.04 shall be without premium or penalty, except as required under Section 5.02.

     Section 3.05 Fees.

          (a) Commitment Fees. Except as otherwise provided in Section 4.03(c), the
Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee,
which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused
amount of the Commitment of such Lender during the period from and including the Effective Date to
but excluding the Termination Date. Accrued commitment fees shall be payable in arrears on the last
day of March, June, September and December of each year and on the Termination Date, commencing on
the first such date to occur after the date hereof. All commitment fees shall be computed on the
basis of a year of 360 days, unless such computation would cause interest on the Notes or on other
Obligations hereunder to exceed the Highest Lawful Rate, in which case such fees and interest shall
be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable
for the actual number of days elapsed (including the first day but excluding the last day).

          (b) Letter of Credit Fees. The Borrower agrees to pay to the Administrative Agent
for the account of each Lender a participation fee with respect to its participations in Letters of
Credit, which shall accrue at the same Applicable Margin used to determine the interest rate
applicable to Eurodollar Loans on the average daily amount of such Lender’s LC

40

 

Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during
the period from and including the date of this Agreement to but excluding the later of the date on
which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC
Exposure, to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum
on the average daily amount of the LC Exposure (excluding any portion thereof attributable to
unreimbursed LC Disbursements) during the period from and including the date of this Agreement to
but excluding the later of the date of termination of the Commitments and the date on which there
ceases to be any LC Exposure, provided that in no event shall such fee be less than $500
during any quarter, and to the Issuing Bank, for its own account, its standard fees with respect
to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings
thereunder. Participation fees and fronting fees accrued through and including the last day of
March, June, September and December of each year shall be payable on the third (3rd)
Business Day following such last day, commencing on the first such date to occur after the date of
this Agreement; provided that all such fees shall be payable on the Termination Date and
any such fees accruing after the Termination Date shall be payable on demand. Any other fees
payable to the Issuing Bank pursuant to this Section 3.05(b) shall be payable within ten
(10) days after demand. All participation fees and fronting fees shall be computed on the basis of
a year of 360 days, unless such computation would cause interest hereunder to exceed the Highest
Lawful Rate, in which case such fees and interest shall be computed on the basis of a year of 365
days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

          (c) Administrative Agent Fees. The Borrower agrees to pay to the Administrative
Agent, for its own account, fees payable in the amounts and at the times separately agreed upon in
writing between the Borrower and the Administrative Agent, including the fees set forth in the Fee
Letters.

          (d) Arrangers Fees. The Borrower agrees to pay to the Arrangers, for their own
accounts, fees payable in the amounts and at the times separately agreed upon in writing among the
Borrower and the Arrangers, including the fees set forth in the Fee Letters.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs.

     Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

          (a) Payments by the Borrower. The Borrower shall make each payment required to be
made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or
of amounts payable under Section 5.01, Section 5.02, Section 5.03 or
otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available
funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be
fully earned and shall not be refundable under any circumstances absent manifest error. Any
amounts received after such time on any date may, in the discretion of the Administrative Agent, be
deemed to have been received on the next succeeding Business Day for purposes of calculating
interest thereon. All such payments shall be made to the Administrative Agent at its offices
specified in Section 12.01(a), except payments to be made directly to the Issuing Bank as
expressly provided herein and except that payments pursuant to Section 5.01,

41

 

Section 5.02, Section 5.03 and Section 12.03 shall be made directly to
the Persons entitled thereto. The Administrative Agent shall distribute any such payments received
by it for the account of any other Person to the appropriate recipient promptly following receipt
thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for
payment shall be extended to the next succeeding Business Day, and, in the case of any payment
accruing interest, interest thereon shall be payable for the period of such extension. All
payments hereunder shall be made in dollars.

          (b) Application of Insufficient Payments. If at any time insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal,
unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied
first, towards payment of interest and fees then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of interest and fees then due to such parties, and second,
towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among
the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC
Disbursements then due to such parties.

          (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of
set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment
of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements
and accrued interest thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value) participations in the
Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans and participations
in LC Disbursements; provided that if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations shall be rescinded and
the purchase price restored to the extent of such recovery, without interest, and the provisions
of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower
pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a
Lender as consideration for the assignment of or sale of a participation in any of its Loans or
participations in LC Disbursements to any assignee or participant, other than to QRE MLP or any of
its Subsidiaries or Affiliates (as to which the provisions of this Section 4.01(c) shall
apply). Each of QRE MLP and the Borrower consents to the foregoing and agrees, to the extent it
may effectively do so under applicable law, that any Lender acquiring a participation pursuant to
the foregoing arrangements may exercise against the Borrower and any other Obligor rights of
set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of the Borrower or such other Obligor in the amount of such participation.

     Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent
shall have received notice from the Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not
make such payment, the Administrative Agent may assume that the Borrower has made such payment on
such date in accordance herewith and may, in reliance upon such assumption, distribute to the
Lenders or the Issuing Bank, as the case may be, the amount due.

42

 

In such event, if the Borrower has not in fact made such payment, then each of the Lenders or
the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent
forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon,
for each day from and including the date such amount is distributed to it to but excluding the date
of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a
rate determined by the Administrative Agent in accordance with banking industry rules on interbank
compensation.

     Section 4.03 Deductions by the Administrative Agent; Defaulting Lenders.

          (a) Certain Deductions by the Administrative Agent. If any Lender shall fail to make
any payment required to be made by it pursuant to Section 2.05(b), Section 2.08(d),
Section 2.08(e), Section 4.01(c), Section 4.02 or Section 12.03(c)
then the Administrative Agent may, in its discretion (notwithstanding any contrary provision
hereof), apply any amounts thereafter received by the Administrative Agent for the account of such
Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied
obligations are fully paid.

          (b) Payments to Defaulting Lenders. If a Defaulting Lender (or a Lender who would be
a Defaulting Lender but for the expiration of the relevant grace period) as a result of the
exercise of a set off shall have received a payment in respect of its Revolving Credit Exposure
which results in its Revolving Credit Exposure being less than its Applicable Percentage of the
aggregate Revolving Credit Exposures, then no payment will be made to such Defaulting Lender until
all amounts due and owing to the Lenders have been equalized in accordance with each Lender’s
respective pro rata share of the Obligations. Further, if at any time prior to the acceleration or
maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal
of a Loan or a reimbursement of an LC Disbursement while one or more Defaulting Lenders shall be
party to this Agreement, the Administrative Agent shall apply such payment first to the
Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until
such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender)
is owed its Applicable Percentage of all Loans then outstanding. After acceleration or maturity of
the Loans, subject to the first sentence of this Section 4.03(b), all principal will be
paid ratably as provided in Section 10.02(c).

          (c) Defaulting Lenders. Notwithstanding any provision of this Agreement to the
contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for
so long as such Lender is a Defaulting Lender:

               (i) Fees otherwise payable pursuant to Section 3.05(a) shall cease to accrue on the
unfunded portion of the Commitment of such Defaulting Lender.

               (ii) The Commitment and the principal amount of the Loans and participation interests in
Letters of Credit of such Defaulting Lender shall not be included in determining whether all
Lenders, the Majority Lenders, the Required Lenders or the Supermajority Lenders have taken or may
take any action hereunder (including any consent to any amendment or waiver pursuant to
Section 12.02), provided that any waiver, amendment or modification (A) that would
increase the Commitment or the Maximum Credit Amount of such Defaulting Lender or that would amend
this Section 4.03(c)(ii) in any manner that would result

43

 

in such Defaulting Lender’s right to vote as provided herein being further restricted or (B)
requiring the consent of all Lenders or each adversely affected Lender which affects such
Defaulting Lender differently than all other Lenders or all other adversely affected Lenders, as
the case may be, shall require the consent of such Defaulting Lender; and provided further
that any redetermination or affirmation of the Borrowing Base shall occur without the
participation of a Defaulting Lender, but the Commitment (i.e. the Applicable Percentage of the
Borrowing Base of a Defaulting Lender) may not be increased without the consent of such Defaulting
Lender.

               (iii) If any LC Exposure exists at the time a Lender becomes a Defaulting Lender then:

                    (A) all or any part of such LC Exposure shall be reallocated among the Non-Defaulting Lenders
in accordance with their respective Applicable Percentages (for the purposes of such reallocation
the Defaulting Lender’s Commitment shall be disregarded in determining the Non-Defaulting Lender’s
Applicable Percentage) but only to the extent (x) the sum of all Non-Defaulting Lenders’ Revolving
Credit Exposures plus such Defaulting Lender’s LC Exposure does not exceed the total of all
Non-Defaulting Lenders’ Commitments, (y) the conditions set forth in Section 6.02 are
satisfied at such time and (z) the sum of each Non-Defaulting Lender’s Revolving Credit Exposure
plus its reallocated share of such Defaulting Lender’s LC Exposure does not exceed such
Non-Defaulting Lender’s Commitment;

                    (B) if the reallocation described in clause (A) above cannot, or can only partially, be
effected, then the Borrower shall within one (1) Business Day following notice by the
Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure (after giving effect
to any partial reallocation pursuant to clause (A) above) in accordance with the procedures set
forth in Section 2.08(j) for so long as such LC Exposure is outstanding and the relevant
Defaulting Lender remains a Defaulting Lender;

                    (C) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure
pursuant to this Section 4.03 then the Borrower shall not be required to pay any fees to
such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting Lender’s
LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

                    (D) if the applicable LC Exposure of the Non-Defaulting Lenders is reallocated pursuant to
this Section 4.03(c), then the fees payable to the Lenders pursuant to Section
3.05(a) and Section 3.05(b) shall be adjusted in accordance with such Non-Defaulting
Lenders’ Applicable Percentages; or

                    (E) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated
pursuant to Section 4.03(c)(iii), then, without prejudice to any rights or remedies of the
Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have been payable to
such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment
that was utilized by such LC Exposure) under Section 3.05(a) and letter of credit fees
payable under Section 3.05(b) with respect to such Defaulting

44

 

Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash
collateralized and/or reallocated.

          (d) So long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to
issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure
will be one hundred percent (100%) covered by the Commitments of the Non-Defaulting Lenders and/or
cash collateral will be provided by the Borrower in accordance with Section 4.03(c), and
participating interests in any such newly issued or increased Letter of Credit shall be allocated
among Non-Defaulting Lenders in a manner consistent with Section 4.03(c)(iii) (and
Defaulting Lenders shall not participate therein).

          (e) In the event that the Administrative Agent, the Borrower and the Issuing Bank each agrees
that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a
Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion
of such Lender’s Commitment and on such date, if necessary as a result of a Loan funding pursuant
to Section 2.08(e), such Lender shall purchase at par such of the Loans of the other
Lenders as the Administrative shall determine may be necessary in order for such Lender to hold
such Loans in accordance with its Applicable Percentage.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment
by the Obligors unto and in favor of the Administrative Agent for the benefit of the Lenders, the
Secured Hedging Providers and the Secured Treasury Management Counterparties of all of the
Obligors’ interest in and to production and all proceeds attributable thereto which may be produced
from or allocated to the Mortgaged Property. The Security Instruments further provide in general
for the application of such proceeds to the satisfaction of the Obligations and other obligations
described therein and secured thereby. Notwithstanding the assignment contained in such Security
Instruments, until the occurrence of an Event of Default, the Administrative Agent and the Lenders
agree that they will neither notify the purchaser or purchasers of such production nor take any
other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but
the Lenders will instead permit such proceeds to be paid to the applicable Obligor and the Lenders
hereby authorize the Administrative Agent to take such actions as may be necessary to cause such
proceeds to be paid to applicable Obligor.

ARTICLE V

Increased Costs; Break Funding Payments; Taxes; Illegality

     Section 5.01 Increased Costs.

          (a) Eurodollar Changes in Law. If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of, or credit extended by, any Lender (except
any such reserve requirement reflected in the Adjusted LIBO Rate); or

               (ii) impose on any Lender or the London interbank market any other condition affecting this
Agreement or Eurodollar Loans made by such Lender;

45

 

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to
reduce the amount of any sum received or receivable by such Lender (whether of principal, interest
or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

          (b) Capital Requirements. If any Lender or the Issuing Bank determines that any
Change in Law regarding capital requirements has or would have the effect of reducing the rate of
return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the
Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or
participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the
Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the
Issuing Bank’s holding company could have achieved but for such Change in Law (taking into
consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the
Issuing Bank’s holding company with respect to capital adequacy), then from time to time the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or
amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s
holding company for any such reduction suffered.

          (c) Certificates. A certificate of a Lender or the Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company,
as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to
the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or
the Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten
(10) days after receipt thereof.

          (d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the
part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01
shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such
compensation; provided that the Borrower shall not be required to compensate a Lender or
the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions
incurred more than 180 days prior to the date that such Lender or the Issuing Bank, as the case may
be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions
and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs or
reductions is retroactive, then the 180-day period referred to above shall be extended to include
the period of retroactive effect thereof.

     Section 5.02 Break Funding Payments. In the event of the payment of any principal of
any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including
as a result of an Event of Default), the conversion of any Eurodollar Loan into an ABR Loan other
than on the last day of the Interest Period applicable thereto, the failure to borrow, convert,
continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant
hereto or the assignment or purchase of any Eurodollar Loan other than on the last day of the
Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section
5.04(b), then, in any such event, the Borrower shall compensate each Lender for the loss, cost
and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or
expense to any Lender shall be deemed to include an amount determined by such Lender to be

46

 

the excess, if any, of the amount of interest which would have accrued on the principal
amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been
applicable to such Loan, for the period from the date of such event to the last day of the then
current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for
the period that would have been the Interest Period for such Loan), over the amount of interest
which would accrue on such principal amount for such period at the interest rate which such Lender
would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable
amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section 5.02 and reasonably detailed calculations therefor, upon
request of the Borrower, shall be delivered to the Borrower and shall be conclusive absent manifest
error. The Borrower shall pay such Lender the amount shown as due on any such certificate within
ten (10) days after receipt thereof.

     Section 5.03 Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of the Borrower or any other Obligor under any Loan Document shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower
or any other Obligor shall be required to deduct any Indemnified Taxes or Other Taxes from such
payments, then the sum payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under this Section
5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an
amount equal to the sum it would have received had no such deductions been made, the Borrower or
such other Obligor shall make such deductions and the Borrower or such other Obligor shall pay the
full amount deducted to the relevant Governmental Authority in accordance with applicable law.

          (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

          (c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative
Agent, each Lender and the Issuing Bank, within ten (10) days after written demand therefor, for
the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such
Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account
of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section 5.03) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto. A written demand under
this Section 5.03(c) shall include a certificate of the Administrative Agent, a Lender or
the Issuing Bank specifying the amount and description of such payment or liability under this
Section 5.03.

          (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower or any other Obligor to a Governmental Authority, the Borrower
shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by
such Governmental Authority evidencing such payment, a copy of the

47

 

return reporting such payment or other evidence of such payment reasonably satisfactory to the
Administrative Agent.

          (e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or
any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or
any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation
prescribed by applicable law or reasonably requested by the Borrower as will permit such payments
to be made without withholding or at a reduced rate.

          (f) FATCA. If a payment made to a Lender under this Agreement would be subject to
U.S. Federal withholding Tax imposed by FATCA if such Lender fails to comply with the applicable
reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the
Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times
prescribed by law and at such time or times reasonably requested by the Withholding Agent, such
documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of
the Code) and such additional documentation reasonably requested by the Withholding Agent as may be
necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that
such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to
deduct and withhold from such payment.

     Section 5.04 Mitigation Obligations; Replacement of Lenders.

          (a) Designation of Different Lending Office. If any Lender requests compensation
under Section 5.01, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to Section
5.03, then such Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another
of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or
assignment would eliminate or reduce amounts payable pursuant to Section 5.01 or
Section 5.03, as the case may be, in the future and would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The
Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

          (b) Replacement of Lenders. If (i) any Lender requests compensation under Section
5.01, (ii) the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 5.03, (iii) any
Lender becomes a Defaulting Lender, or (iv) any Lender fails to approve or consent to a requested
amendment, waiver or other action (including increasing or maintaining the Borrowing Base) when the Supermajority Lenders have provided their approval or consent to such amendment,
waiver or other action, then the Borrower may, at its sole expense and effort, upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse
(in accordance with and subject to the restrictions contained in Section 12.04(b)), all its
interests, rights and obligations under this Agreement to an assignee that shall assume such

48

 

obligations (which assignee may be another Lender, if a Lender accepts such assignment);
provided that the Borrower shall have received the prior written consent of the
Administrative Agent, which consent shall not unreasonably be withheld, such Lender shall have
received payment of an amount equal to the outstanding principal of its Loans and participations in
LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and
fees) or the Borrower (in the case of all other amounts) and in the case of any such assignment
resulting from a claim for compensation under Section 5.01 or payments required to be made
pursuant to Section 5.03, such assignment will result in a reduction in such compensation
or payments. A Lender shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply.

     Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in
the event that it becomes unlawful for any Lender or its applicable lending office to honor its
obligation to make or maintain Eurodollar Loans either generally or having a particular Interest
Period hereunder, then such Lender shall promptly notify the Borrower and the Administrative Agent
thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the
“Affected Loans”) until such time as such Lender may again make and maintain such
Eurodollar Loans and all Affected Loans which would otherwise be made by such Lender shall be made
instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the
Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically
converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent
that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which
would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR
Loans.

ARTICLE VII

Representations and Warranties

     Each of QRE MLP and the Borrower represents and warrants to the Lenders that:

     Section 7.01 Organization; Powers. Each of the General Partner and the Obligors is
duly organized, validly existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority, and has all material governmental licenses,
authorizations, consents and approvals necessary, to own its assets and to carry on its business as
now conducted, and is qualified to do business in or has applied to qualify to do business in, and
is in good standing in, every jurisdiction where such qualification is required, except where
failure to have such power, authority, licenses, authorizations, consents, approvals and
qualifications could not reasonably be expected to have a Material Adverse Effect.

     Section 7.02 Authority; Enforceability. The Transactions are within each Obligor’s
corporate, company or partnership powers and have been duly authorized by all necessary corporate,
limited liability company or partnership action and, if required, stockholder, member or partner
action (including, without limitation, any action required to be taken by any class of directors of
the General Partner, any Obligor or any other Person, whether interested or disinterested, in order
to ensure the due authorization of the Transactions). Each Loan Document and each Transaction
Document to which each Obligor is a party has been duly executed and delivered by such Obligor and
constitutes a legal, valid and binding obligation of such Obligor, enforceable in accordance with
its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors’ rights generally and subject to general principles of equity, regardless of
whether considered in a proceeding in equity or at law.

     Section 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent
or approval of, registration or filing with, or any other action by, any Governmental Authority or
any other third Person (including shareholders, members, partners or any class of directors or
managers, whether interested or disinterested, of the General Partner, any Obligor or any other
Person), nor is any such consent, approval, registration, filing or other action necessary for the
validity or enforceability of any Loan Document or the consummation of the transactions
contemplated thereby, except such as have been obtained or made and are in full force and effect
other than (i) the recording and filing of the Security Instruments as required by this Agreement
and (ii) those third party approvals or consents which, if not made or obtained, would not cause a
Default hereunder, could not reasonably be expected to have a Material Adverse Effect or do not

53

 

have an adverse effect on the enforceability of the Loan Documents, (b) will not violate any
applicable law or regulation or the charter, by-laws or other organizational documents of the
General Partner or any Obligor or any order of any Governmental Authority, (c) will not violate or
result in a default under any indenture, agreement or other instrument binding upon the General
Partner, the Obligors or their Properties, or give rise to a right thereunder to require any
payment to be made by the General Partner or any Obligor and (d) will not result in the creation or
imposition of any Lien on any Property of the General Partner or any Obligor (other than the Liens
created by the Loan Documents).

     Section 7.04 Financial Condition; No Material Adverse Change.

          (a) The Borrower has heretofore furnished to the Lenders the Initial Financial Statements, in
form and substance reasonably satisfactory to the Administrative Agent.

          (b) Since December 31, 2009, there has been no event, development or circumstance that has had
or could reasonably be expected to have a Material Adverse Effect.

          (c) No Obligor is a party to any agreement or instrument or subject to any corporate or other
constitutional restriction that has resulted or could reasonably be expected to result in a
Material Adverse Effect. No Obligor is in default in any manner under any provision of any
indenture or other agreement or instrument evidencing Debt, or any other agreement or instrument to
which it is a party or by which it or any of its Property is or may be bound, where such default
could reasonably be expected to result in a Material Adverse Effect, and no condition exists which,
with the giving of notice or the lapse of time or both, would constitute such a default.

     Section 7.05 Litigation. Except as set forth on Schedule 7.05, there are no
actions, suits, investigations or proceedings by or before any arbitrator or Governmental Authority
pending against or, to the knowledge of the General Partner, QRE MLP or the Borrower, threatened
against or affecting the General Partner or any Obligor or involving the Transactions as to which
there is a reasonable possibility of an adverse determination that, if adversely determined, could
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or
that involve any Loan Document, any Transaction Documents or the Transactions.

     Section 7.06 Environmental Matters. Except for such matters that, individually or in
the aggregate, could not reasonably be expected to have a Material Adverse Effect:

          (a) no Property of QRE MLP or any of its Subsidiaries nor the operations conducted thereon
violate any order or requirement of any court or Governmental Authority or any Environmental Laws.

          (b) no Property of QRE MLP or any of its Subsidiaries nor the operations currently conducted
thereon or, to the knowledge of the General Partner, QRE MLP or the Borrower, by any prior owner or
operator of such Property or operation, are in violation of or subject to any existing, pending or
threatened action, suit, investigation, inquiry or proceeding by or before any court or
Governmental Authority or to any remedial obligations under Environmental Laws.

54

 

          (c) all notices, permits, licenses, exemptions, approvals or similar authorizations, if any,
required to be obtained or filed in connection with the operation or use of any and all Property of
QRE MLP and each of its Subsidiaries, including, without limitation, past or present treatment,
storage, disposal or release of a hazardous substance, oil and gas waste or solid waste into the
environment, have been duly obtained or filed, and QRE MLP and each of its Subsidiaries are in
compliance with the terms and conditions of all such notices, permits, licenses and similar
authorizations.

          (d) all hazardous substances, solid waste and oil and gas waste, if any, generated at any and
all Property of QRE MLP or any of its Subsidiaries have in the past been transported, treated and
disposed of in accordance with Environmental Laws and so as not to pose an imminent and substantial
endangerment to public health or welfare or the environment, and, to the knowledge of the General
Partner, QRE MLP or the Borrower, all such transport carriers and treatment and disposal facilities
have been and are operating in compliance with Environmental Laws and so as not to pose an imminent
and substantial endangerment to public health or welfare or the environment, and are not the
subject of any existing, pending or threatened action, investigation or inquiry by any Governmental
Authority in connection with any Environmental Laws.

          (e) each of QRE MLP and the Borrower has taken reasonable steps to determine and has
determined that no oil, hazardous substances, solid waste or oil and gas waste, have been disposed
of or otherwise released and there has been no threatened release of any oil, hazardous substances,
solid waste or oil and gas waste on or to any Property of QRE MLP or any of its Subsidiaries except
in compliance with Environmental Laws and so as not to pose an imminent and substantial
endangerment to public health or welfare or the environment.

          (f) to the extent applicable, all Property of QRE MLP and each of its Subsidiaries currently
satisfies all design, operation, and equipment requirements imposed by the OPA, and none of the
General Partner, QRE MLP and the Borrower has any reason to believe that such Property, to the
extent subject to the OPA, will not be able to maintain compliance with the OPA requirements during
the term of this Agreement.

          (g) neither QRE MLP nor any of its Subsidiaries has any known contingent liability or Remedial
Work in connection with any release or threatened release of any oil, hazardous substance, solid
waste or oil and gas waste into the environment.

     Section 7.07 Compliance with the Laws and Agreements; No Defaults.

          (a) Each of the Borrower and the other Obligors is in compliance with all Governmental
Requirements applicable to it or its Property and all agreements and other instruments binding upon
it or its Property, and possesses all licenses, permits, franchises, exemptions, approvals and
other governmental authorizations necessary for the ownership of its Property and the conduct of
its business, except where the failure to do so, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

          (b) Each of the Borrower and the other Obligors is not in default nor has any event or
circumstance occurred which, but for the expiration of any applicable grace period or

55

 

the giving of notice, or both, would constitute a default or would require the Borrower or any
other Obligor to Redeem or make any offer to Redeem under any indenture, note, credit agreement or
instrument pursuant to which any Material Debt is outstanding or by which the Borrower or any other
Obligor or any of their Properties is bound.

          (c) No Default has occurred and is continuing.

     Section 7.08 Investment Company Act. Neither QRE MLP nor any of its Subsidiaries is
an “investment company” or a company “controlled” by an “investment company,” within the meaning
of, or subject to regulation under, the Investment Company Act of 1940, as amended.

     Section 7.09 Taxes. Each of the Borrower and the other Obligors has timely filed or
caused to be filed all Tax returns and reports required to have been filed and has paid or caused
to be paid all Taxes required to have been paid by it, except Taxes that are being contested in
good faith by appropriate proceedings and for which the Borrower or such other Obligor, as
applicable, has set aside on its books adequate reserves in accordance with GAAP or to the extent
that the failure to do so could not reasonably be expected to result in a Material Adverse Effect.
The charges, accruals and reserves on the books of the Borrower and each other Obligor in respect
of Taxes and other governmental charges are, in the reasonable opinion of the General Partner,
adequate. No Tax Lien has been filed and, to the knowledge of the General Partner, no claim is
being asserted with respect to any such Tax or other such governmental charge.

     Section 7.10 ERISA.

          (a) QRE MLP, the Subsidiaries and each ERISA Affiliate have complied in all material respects
with ERISA and, where applicable, the Code regarding each Plan.

          (b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where
applicable, the Code.

          (c) No act, omission or transaction has occurred which could result in imposition on QRE MLP,
any of its Subsidiaries or any ERISA Affiliate (whether directly or indirectly) of either a civil
penalty assessed pursuant to subsections (c), (i) or (l) of section 502 of ERISA or a tax imposed
pursuant to Chapter 43 of Subtitle D of the Code or breach of fiduciary duty liability damages
under section 409 of ERISA which civil penalty or tax could reasonably be expected to result in a
Material Adverse Effect.

          (d) No ERISA Event with respect to any Plan has occurred or is reasonably likely to occur
which could reasonably be expected to result in a Material Adverse Effect.

          (e) Full payment when due has been made of all amounts which QRE MLP, any Subsidiary or any
ERISA Affiliate is required under the terms of each Plan or applicable law to have paid as
contributions to such Plan as of the date hereof, and no accumulated funding deficiency (as defined
in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to
any Plan.

          (f) The actuarial present value of the benefit liabilities under each Plan which is subject to
Title IV of ERISA does not, as of the end of QRE MLP’s most recently ended fiscal

56

 

year, exceed the current value of the assets (computed on a plan termination basis in
accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities. The term
“actuarial present value of the benefit liabilities” shall have the meaning specified in section
4041 of ERISA.

          (g) Neither QRE MLP, any Subsidiary nor any ERISA Affiliate sponsors, maintains, or
contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including,
without limitation, any such plan maintained to provide benefits to former employees of such
entities, that may not be terminated by QRE MLP, a Subsidiary or any ERISA Affiliate in its sole
discretion at any time without any material liability.

          (h) Neither QRE MLP, any Subsidiary nor any ERISA Affiliate sponsors, maintains or contributes
to, or has at any time in the six-year period preceding the date hereof sponsored, maintained or
contributed to, any Multiemployer Plan.

under section 401(a)(29) of the Code due to a Plan amendment that results in an increase in current
liability for the Plan.

     Section 7.11 Disclosure; No Material Misstatements. Neither (a) any written
information, report, financial statement, certificate, Borrowing Request, request for a Letter of
Credit, exhibit or schedule furnished by or on behalf of any Obligor to the Administrative Agent or
any Lender in connection with the negotiation of any Loan Document or included therein or delivered
pursuant thereto, taken as a whole, (b) the Confidential Information Memorandum dated November
2010, nor (c) any statements or conclusions in any Reserve Report, contained or contains any
material misstatement of fact or omitted or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were or are made, not
misleading as of the date such information is dated or certified; provided that (i) to the
extent any such information, report, financial statement, exhibit or schedule was based upon or
constitutes a forecast or projection, the Borrower represents only that it acted in good faith and
utilized reasonable assumptions and due care in the preparation of such forecast or projection (it
being recognized by the Lenders, however, that projections as to future events are not to be viewed
as facts and that results during the period(s) covered by such projections may differ from the
projected results and that such differences may be material and that the Borrower makes no
representation that such projections will be realized) and (ii) as to statements, information and
reports supplied by third parties after the Effective Date, the Borrower represents only that it is
not aware of any material misstatement or omission therein.

     Section 7.12 Insurance. QRE MLP has, and has caused all of its Subsidiaries to have,
all insurance policies sufficient for the compliance by each of them with all material Governmental
Requirements and all material agreements and insurance coverage in at least amounts and against
such risk (including, without limitation, public liability) that are usually insured against by
companies similarly situated and engaged in the same or a similar business for the assets and
operations of QRE MLP and its Subsidiaries. The Administrative Agent has been named as an
additional insured in respect of such liability insurance policies and the Administrative Agent has
been named as loss payee with respect to property loss insurance.

     Section 7.15 Properties; Titles, Etc.

          (a) Each of the Borrower and its Subsidiaries has good and defensible title to the Oil and Gas
Properties evaluated in the most recently delivered Reserve Report and each of QRE MLP and its
Subsidiaries has good title to all of its personal Properties, in each case, free and clear of all
Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted
Liens, the Borrower or the Subsidiary specified as the owner owns the net interests in production
attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve
Report, and the ownership of such Properties shall not in any material respect obligate the
Borrower or such Subsidiary to bear the costs and expenses relating to the maintenance, development
and operations of each such Property in an amount in excess of the working interest of each
Property set forth in the most recently delivered Reserve Report that is not offset by a
corresponding proportionate increase in the Borrower’s or such Subsidiary’s net revenue interest in
such Property.

          (b) All material leases and agreements necessary for the conduct of the business of QRE MLP
and its Subsidiaries are valid and subsisting, in full force and effect, and there exists no
default or event or circumstance which with the giving of notice or the passage of

58

 

time or both would give rise to a default under any such leases or agreements, which could
reasonably be expected to have a Material Adverse Effect.

          (c) QRE MLP and each of its Subsidiaries owns, or is licensed to use, all trademarks,
tradenames, copyrights, patents and other intellectual Property material to its business, and the
use thereof by QRE MLP or such Subsidiary does not infringe upon the rights of any other Person,
except for any such infringements that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect. QRE MLP and its Subsidiaries either own or have
valid licenses or other rights to use all databases, geological data, geophysical data, engineering
data, seismic data, maps, interpretations and other technical information used in their businesses
as presently conducted, subject to the limitations contained in the agreements governing the use of
the same, which limitations are customary for companies engaged in the business of the exploration
and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a
Material Adverse Effect.

     Section 7.16 Maintenance of Properties. Except for such acts or failures to act as
could not be reasonably expected to have a Material Adverse Effect, the Oil and Gas Properties (and
Properties unitized therewith) have been maintained, operated and developed in a good and
workmanlike manner and in conformity with all Governmental Requirements and in conformity with the
provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon
Interests and other contracts and agreements forming a part of the Oil and Gas Properties.
Specifically in connection with the foregoing, except for those as could not be reasonably expected
to have a Material Adverse Effect, no Oil and Gas Property is subject to having allowable
production reduced below the full and regular allowable (including the maximum permissible
tolerance) because of any overproduction (whether or not the same was permissible at the time) and
none of the wells comprising a part of the Oil and Gas Properties (or Properties unitized
therewith) is deviated from the vertical more than the maximum permitted by Governmental
Requirements, and such wells are, in fact, bottomed under and are producing from, and the well
bores are wholly within, the Oil and Gas Properties (or in the case of wells located on Properties
unitized therewith, such unitized Properties). All pipelines, wells, gas processing plants,
platforms and other material improvements, fixtures and equipment owned in whole or in part by QRE
MLP or any of its Subsidiaries that are necessary to conduct normal operations are being maintained
in a state adequate to conduct normal operations, and with respect to such of the foregoing which
are operated by the Borrower or any of its Subsidiaries, in a manner consistent with customary
industry practices (other than those the failure of which to maintain in accordance with this
Section 7.16 could not reasonably be expected to have a Material Adverse Effect).

     Section 7.17 Gas Imbalances, Prepayments. Except as set forth on Schedule
7.17 or on the most recent certificate delivered pursuant to Section 8.12(c), on a net
basis there are no gas imbalances, take or pay or other prepayments which would require QRE MLP or
any of its Subsidiaries to deliver, in the aggregate, one-fourth of one percent (0.25%) or more of
QRE MLP’s and its Subsidiaries’ proved reserves (calculated at the Effective Date or the “as of”
date of such certificates, as applicable) at some future time without then or thereafter receiving
full payment therefor.

59

 

     Section 7.18 Marketing of Production. Except for contracts listed and in effect on
the date hereof on Schedule 7.18, and thereafter either disclosed in writing to the
Administrative Agent or included in the most recently delivered Reserve Report (with respect to all
of which contracts the Borrower represents that it or its Subsidiaries are receiving a price for
all production sold thereunder which is computed substantially in accordance with the terms of the
relevant contract and are not having deliveries curtailed substantially below the subject
Property’s delivery capacity, except as disclosed in Schedule 7.18 or the most recently
delivered Reserve Report), no material agreements exist which are not cancelable on sixty (60) days
notice or less without penalty or detriment for the sale of production from the Borrower’s or its
Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights to purchase,
production, whether or not the same are currently being exercised) that pertain to the sale of
production at a fixed price and have a maturity or expiry date of longer than six (6) months.

     Section 7.19 Swap Agreements. Schedule 7.19, as of the date hereof, and after
the date hereof, each report required to be delivered by the Borrower pursuant to Section
8.01(e), as of the date of such report, sets forth, a true and complete list of all Swap
Agreements of QRE MLP and each Subsidiary, the material terms thereof (including the type, term,
effective date, termination date and notional amounts or volumes), the net mark to market value
thereof, all credit support agreements relating thereto (including any margin required or supplied)
and the counterparty to each such agreement. For purposes of this Section 7.19, the net
mark-to-market value shall with respect to reports required to be delivered by the Borrower
pursuant to Section 8.01(e), be calculated as of the date of the financial statements
concurrently delivered pursuant to Section 8.01(a) or Section 8.01(b), as
applicable.

     Section 7.20 Use of Loans and Letters of Credit. The proceeds of the Loans and the
Letters of Credit shall be used (i) to provide funds for the exploration, development and/or
acquisition of oil and gas properties, including, without limitation, the acquisition by the
Obligors of the Assets to be acquired pursuant to the Transaction Documents, including the
repayment of debt assumed in connection with the acquisition of the Assets and (ii) for working
capital and other general corporate purposes, including permitted Restricted Payments;
provided that if the Borrowing Base Utilization Percentage is equal to or exceeds 95%
before or after giving effect to the requested Loan or Letter of Credit, then no proceeds of any
Loan or any Letter of Credit shall be used to fund Restricted Payments under Section 9.04.
QRE MLP and its Subsidiaries are not engaged principally, or as one of its or their important
activities, in the business of extending credit for the purpose, whether immediate, incidental or
ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the
Board). No part of the proceeds of any Loan or Letter of Credit will be used for any purpose which
violates the provisions of Regulations T, U or X of the Board.

     Section 7.21 Solvency. After giving effect to the Transactions contemplated hereby,
(a) the aggregate assets (after giving effect to amounts that are expected to reasonably be
received by reason of indemnity, offset, insurance or any similar arrangement), at a fair
valuation, of the Borrower and the other Obligors, taken as a whole, exceed the aggregate Debt of
the Borrower and the other Obligors on a consolidated basis, (b) each of the Borrower and the other
Obligors have not incurred and do not intend to incur, and do not believe that it has incurred,
Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash
it expects to receive and the amounts it expects to be payable on or in respect of

60

 

its liabilities, and giving effect to amounts that it expects could reasonably be received by
reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute
and matures and (c) each of the Borrower and the other Obligors do not have (and do not have reason
to believe that it will have thereafter) unreasonably small capital for the conduct of its
business.

     Section 7.22 Anti-Terrorism Laws.

          (a) Neither QRE MLP nor the Borrower is, and to the knowledge of the General Partner, none of
QRE MLP’s or the Borrower’s Affiliates, officers or directors is in violation of any Governmental
Requirement relating to terrorism or money laundering (“Anti-Terrorism Laws”), including
Executive Order No. 13224 on Terrorist Financing, effective September 24, 2001 (the “Executive

Intercept and Obstruct Terrorism Act of 2001, Public Law 107-56, and the Trading with the Enemy
Act, 50 U.S.C. App. 1 et seq., in each case, as amended from time to time.

          (b) Neither QRE MLP nor the Borrower is, and to the knowledge of the General Partner, none of
QRE MLP’s or the Borrower’s Affiliates, officers, directors, brokers or other agent of QRE MLP or
the Borrower acting or benefiting in any capacity in connection with the Loans is, any of the
following:

the Executive Order;

               (ii) a Person owned or controlled by, or acting for or on behalf of, any Person that is
listed in the annex to, or is otherwise subject to the provisions of, the Executive Order;

               (iii) a Person with which any Lender is prohibited from dealing or otherwise engaging in any
transaction by any Anti-Terrorism Law;

               (iv) a Person that commits, threatens or conspires to commit or supports “terrorism” as
defined in the Executive Order; or

               (v) a Person that is named as a “specially designated national and blocked Person” on the
most current list published by the U.S. Treasury Department Office of Foreign Assets Control
(“OFAC”) at its official website or any replacement website or other replacement official
publication of such list.

          (c) No Obligor and, to the knowledge of the General Partner, no broker or other agent of any
Obligor acting in any capacity in connection with the Loans (i) conducts any business or engages in
making or receiving any contribution of funds, goods or services to or for the benefit of any
Person described in paragraph (b) above, (ii) deals in, or otherwise engages in any transaction
relating to, any Property or interests in Property blocked pursuant to the Executive Order, or
(iii) engages in or conspires to engage in any transaction that evades or avoids, or has the
purpose of evading or avoiding, or attempts to violate, any of the prohibitions set forth in any
Anti-Terrorism Law.

     Section 8.04 Payment of Obligations. QRE MLP will, and will cause each of its
Subsidiaries to, pay its obligations, including Tax liabilities of QRE MLP and all of its

amount thereof is being contested in good faith by appropriate proceedings, QRE MLP or such
Subsidiary has set aside on its books adequate reserves with respect thereto in accordance with

Environmental Laws (excluding routine testing and corrective action) if the General Partner
reasonably anticipates that such action will result in liability (whether

67

other means of recovery or reimbursement acceptable to the Lenders, subject to normal deductibles.

          (c) QRE MLP and the Borrower will, and will cause each Subsidiary of the Borrower to, provide

evidence and more fully describe the Collateral intended as security for the Obligations, or to
correct any omissions in this Agreement or the Security Instruments, or to state more fully the
obligations secured therein, or to perfect, protect or preserve any Liens created pursuant to this
Agreement or any of the Security Instruments or the priority thereof, or to make any recordings,

sole discretion of the Administrative Agent, in connection therewith.

          (b) Each of QRE MLP and the Borrower hereby authorizes the Administrative Agent to file one or

     Section 8.12 Reserve Reports.

          (a) On or before March 15 and September 15 of each year, commencing March 15, 2011, the
Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report evaluating the
Oil and Gas Properties of the Borrower and its Subsidiaries as of the immediately preceding
December 31 and June 30, respectively. The Reserve Report as of December 31 of each year shall be
prepared by one or more Approved Petroleum Engineers or by or under the supervision of an Internal
Petroleum Engineer and audited by one or more Approved Petroleum Engineers, and the June 30 Reserve
Report of each year shall be prepared by or under the supervision of an Internal Petroleum Engineer
who shall certify such Reserve Report to be true and accurate in all material respects and to have
been prepared in accordance with the procedures used in the immediately preceding December 31
Reserve Report.

          (b) In the event of an Interim Redetermination, the Borrower shall furnish to the
Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision

68

 

of an Internal Petroleum Engineer who shall certify such Reserve Report to be true and
accurate in all material respects and to have been prepared in accordance with the procedures used
in the immediately preceding December 31 Reserve Report. For any Interim Redetermination requested
by the Administrative Agent or the Borrower pursuant to Section 2.07(b), the Borrower shall
provide such Reserve Report with an “as of” date as required by the Administrative Agent as soon as
possible, but in any event no later than thirty (30) days following the receipt of such request.

          (c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative
Agent and the Lenders a certificate from a Responsible Officer certifying that in all material
respects:

               (i) there are no statements or conclusions in the Reserve Report which are based upon or
include misleading information or fail to take into account material information regarding the
matters reported therein, it being understood that projections concerning volumes attributable to
the Oil and Gas Properties of the Borrower and its Subsidiaries and production and cost estimates
contained in the Reserve Report are necessarily based upon professional opinions, estimates and
projections and that the Borrower and its Subsidiaries do not warrant that such opinions,
estimates and projections will ultimately prove to have been accurate;

               (ii) the Borrower or its Subsidiaries owns good and defensible title to the Oil and Gas
Properties evaluated in such Reserve Report and such Properties are free of all Liens except for
Liens permitted by Section 9.03;

               (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas
imbalances, take or pay or other prepayments in excess of the volume specified in Section
7.17 with respect to the Oil and Gas Properties evaluated in such Reserve Report which would
require QRE MLP or any of its Subsidiaries to deliver Hydrocarbons either generally or produced
from such Oil and Gas Properties at some future time without then or thereafter receiving full
payment therefor;

               (iv) none of the Oil and Gas Properties have been sold since the date of the last Borrowing
Base determination except as set forth on an exhibit to the certificate, which certificate shall
list all of the Oil and Gas Properties sold and in such detail as reasonably required by the
Administrative Agent;

               (v) attached to the certificate is a list of all marketing agreements entered into subsequent
to the later of the date hereof or the most recently delivered Reserve Report which the Borrower
could reasonably be expected to have been obligated to list on Schedule 7.18 had such
agreement been in effect on the date hereof; and

               (vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve
Report that are Mortgaged Properties and demonstrating the percentage of the Borrowing Base that
the value of such Mortgaged Properties represent.

     Section 8.13 Title Information.

69

 

          (a) On or before the date of delivery to the Administrative Agent and the Lenders of each
Reserve Report required by Section 8.12(a), the Borrower will deliver title information in
form and substance reasonably acceptable to the Administrative Agent covering enough of the Oil and
Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding
Reserve Report, so that the Administrative Agent shall have received together with title
information previously delivered to the Administrative Agent, reasonably satisfactory title
information on at least eighty percent (80%) of the total value of the proved Oil and Gas
Properties evaluated by such Reserve Report.

          (b) If the Borrower has provided title information for additional Properties under Section
8.13(a), the Borrower shall, within sixty (60) days of notice from the Administrative Agent
that title defects or exceptions exist with respect to such additional Properties, either cure any
such title defects or exceptions (including defects or exceptions as to priority) which are not
permitted by Section 9.03 raised by such information, substitute acceptable Mortgaged
Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens
described in clauses (e), (g), (h) and (j) of such definition) having an equivalent value or
deliver title information in form and substance reasonably acceptable to the Administrative Agent
so that the Administrative Agent shall have received, together with title information previously
delivered to the Administrative Agent, reasonably satisfactory title information on at least eighty
percent (80%) of the value of the proved Oil and Gas Properties evaluated by such Reserve Report.

          (c) If the Borrower is unable to cure any title defect requested by the Administrative Agent
or the Lenders to be cured within the 60-day period or the Borrower does not comply with the
requirements to provide acceptable title information covering eighty percent (80%) of the value of
the proved Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall
not be a Default, but instead the Administrative Agent and/or the Required Lenders shall have the
right to exercise the following remedy in their sole discretion from time to time, and any failure
to so exercise this remedy at any time shall not be a waiver as to future exercise of such remedy
by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the
Required Lenders are not satisfied with title to any Mortgaged Property after the 60-day period has
elapsed, such unacceptable Mortgaged Property shall not count towards the eighty percent (80%)
requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that
the then outstanding Borrowing Base shall be reduced by an amount as determined by the
Administrative Agent and approved by the Required Lenders to cause the Borrower to be in compliance
with the requirement to provide acceptable title information on eighty percent (80%) of the value
of the proved Oil and Gas Properties. This new Borrowing Base shall become effective immediately
after receipt of such notice.

     Section 8.14 Collateral; Parent Guaranty. QRE MLP shall (a) at all times
unconditionally guarantee the prompt payment and performance of the Obligations pursuant to the
Guaranty Agreement and (b) grant to the Administrative Agent, pursuant to the Guaranty Agreement, a
perfected, first-priority security interest in 100% of the issued and outstanding Equity Interests
in the Borrower. In connection therewith, QRE MLP shall (i) execute and deliver the Guaranty
Agreement, (ii) pledge 100% of the issued and outstanding Equity Interests in the Borrower
(including, without limitation, delivery of original equity certificates evidencing such Equity
Interests, together with an appropriate undated stock power for each certificate duly

70

 

executed in blank by QRE MLP), and (iii) execute and deliver such other additional closing
documents, certificates and legal opinions as shall reasonably be requested by the Administrative
Agent.

     Section 8.15 Additional Collateral; Additional Obligors.

          (a) In connection with each redetermination of the Borrowing Base, the Borrower shall review
the Reserve Report and the list of current Mortgaged Properties (as described in Section
8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least eighty percent
(80%) of the total value of the Oil and Gas Properties evaluated in the most recently completed
Reserve Report after giving effect to exploration and production activities, acquisitions,
dispositions and production. In the event that the Mortgaged Properties do not represent at least
eighty percent (80%) of such total value, then the Borrower shall, and shall cause its Subsidiaries
to, grant, within thirty (30) days of delivery of the certificate required under Section
8.12(c), to the Administrative Agent as security for the Obligations a first-priority Lien
(provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the
definition thereof may exist, but subject to the proviso at the end of such definition) on
additional Oil and Gas Properties not already subject to a Lien created by the Security
Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least
80% of such total value. All such Liens will be created and perfected by and in accordance with
the provisions of deeds of trust, security agreements and financing statements or other Security
Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in
sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording
purposes.

          (b) The Borrower shall cause (i) each of its Subsidiaries to unconditionally guarantee, on a
joint and several basis, the prompt payment and performance of the Obligations pursuant to the
Guaranty Agreement and to grant a security interest in its assets pursuant to the Security
Agreement and (ii) all of the issued and outstanding Equity Interests in each Subsidiary of the
Borrower to be subject to a perfected, first-priority security interest in favor of the
Administrative Agent pursuant to the Guaranty Agreement. In connection therewith, the Borrower
shall, or shall cause its Subsidiaries, to promptly, but in any event within ten (10) days after
the creation or acquisition (or other similar event) of any Subsidiary, execute and deliver an
amendment or a supplement to the Guaranty Agreement and the Security Agreement as required by the
Administrative Agent, pledge all of the Equity Interests of such Subsidiary (including, without
limitation, delivery of original stock or equity certificates evidencing the Equity Interests of
such Subsidiary, together with an appropriate undated stock powers for each certificate duly
executed in blank by the registered owner thereof) and execute and deliver such other additional
closing documents, certificates and legal opinions as shall reasonably be requested by the
Administrative Agent.

          (c) QRE MLP and the Borrower will at all times cause the other material tangible and
intangible assets (other than deposit accounts) of QRE MLP, the Borrower and each Subsidiary to be
subject to a Lien created by the Security Instruments.

     Section 8.16 ERISA Compliance. QRE MLP will promptly furnish and will cause each of
its Subsidiaries and any ERISA Affiliate to promptly furnish to the Administrative Agent (a)

71

 

upon becoming aware of the occurrence of any ERISA Event which could reasonably be expected to
result in a Material Adverse Effect or of any “prohibited transaction,” as described in section 406
of ERISA or in section 4975 of the Code which could reasonably be expected to result in a Material
Adverse Effect, in connection with any Plan or any trust created thereunder, a written notice
signed by the principal Financial Officer, the Subsidiary or the ERISA Affiliate, as the case may
be, specifying the nature thereof, what action the Borrower, the Subsidiary or the ERISA Affiliate
is taking or proposes to take with respect thereto, and, when known, any action taken or proposed
by the Internal Revenue Service, the Department of Labor or the PBGC with respect thereto, and (b)
immediately upon receipt thereof, copies of any notice of the PBGC’s intention to terminate or to
have a trustee appointed to administer any Plan.

     Section 8.17 Swap Agreements. The Borrower shall maintain the hedge position
established by the Swap Agreements required under Section 6.01(n) during the period
specified therein and shall neither assign, terminate or unwind any such Swap Agreements nor sell
any Swap Agreements if the effect of such action (when taken together with any other Swap
Agreements executed contemporaneously with the taking of such action) would have the effect of
canceling its positions under such Swap Agreements required hereby, except as permitted in
Section 9.18.

     Section 8.18 Marketing Activities. Neither QRE MLP or the Borrower will, and will not
permit any Subsidiary to, engage in marketing activities for any Hydrocarbons or enter into any
contracts related thereto other than (a) contracts for the sale of Hydrocarbons scheduled or
reasonably estimated to be produced from their proved Oil and Gas Properties during the period of
such contract, (b) contracts for the sale of Hydrocarbons scheduled or reasonably estimated to be
produced from proved Oil and Gas Properties of third parties during the period of such contract
associated with the Oil and Gas Properties of the Borrower and its Subsidiaries that the Borrower
or one of its Subsidiaries has the right to market pursuant to joint operating agreements,
unitization agreements or other similar contracts that are usual and customary in the oil and gas
business and (c) other contracts for the purchase and/or sale of Hydrocarbons of third parties (i)
which have generally offsetting provisions (i.e. corresponding pricing mechanics, delivery dates
and points and volumes) such that no “position” is taken and (ii) for which appropriate credit
support has been taken to alleviate the material credit risks of the Borrower and its Subsidiaries
with respect to the counterparty thereto.

     Section 8.19 Patriot Act. The Borrower will, and will cause each other Obligor to,
promptly following a request by the Administrative Agent or any Lender, provide all documentation
and other information that the Administrative Agent or such Lender reasonably requests in order to
comply with its ongoing obligations under the applicable “know your customer” and anti-money
laundering rules and regulations, including the USA Patriot Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the “Patriot Act”).

     Section 8.20 Post-Closing Conditions. So long as the Borrower has delivered, on or
before the Effective Date, title information in form and substance satisfactory to the
Administrative Agent covering at least sixty-eight percent (68%) of the total value of the proved
Oil and Gas Properties evaluated by the Initial Reserve Report, then the Borrower shall be
permitted to, and agrees that it shall, deliver additional title information in form and substance
satisfactory to the Administrative Agent resulting in the delivery of satisfactory title
information

72

 

covering at least eighty percent (80%) of the total value of the proved Oil and Gas Properties
evaluated by the Initial Reserve Report on or before the forty-fifth (45th) day after
the Effective Date (or by such later date as may be agreed to by the Administrative Agent in its
sole discretion), but such later date shall not exceed the ninetieth (90th) day after
the Effective Date unless otherwise approved by the Majority Lenders.

security to such Plan under section 401(a)(29) of the Code.

     Section 9.10 Sale or Discount of Receivables. Except for receivables obtained by the

Property to any other Person (whether now owned or hereafter acquired) (any such transaction, a
“consolidation”) or liquidate, wind-up or dissolve (or suffer any liquidation or
dissolution), terminate or discontinue its business; provided that (a) so long as no
Default or Event of Default has occurred and is continuing, or would result after giving effect
thereto, any Wholly-Owned Subsidiary of the Borrower may participate in a consolidation with any
other Wholly-Owned Subsidiary of the Borrower and the Borrower may participate in a consolidation
with any Wholly-Owned Subsidiary of the Borrower so long as the Borrower is the surviving Person
and (b) any Subsidiary may dissolve, liquidate or wind up its affairs at any time; provided
that such dissolution, liquidation or winding up, as applicable, could not reasonably be expected
to have a Material Adverse Effect.

     Section 9.12 Sale of Properties. QRE MLP will not, and will not permit any of its
Subsidiaries to, sell, assign, farm-out, convey or otherwise transfer any Property except for:

case, in the ordinary course of business;

          (c) the sale or transfer of equipment that is obsolete, worn out or no longer necessary for
the business of the Borrower or such Subsidiary or is replaced by equipment of at

78

 

least comparable value and use and, in each case, is sold or transferred in the ordinary
course of business;

          (d) sales or other dispositions (including Casualty Events), other than as provided in clauses
(a) through (c), of Borrowing Base Properties or any interest therein or Subsidiaries owning
Borrowing Base Properties; provided that with respect to any portion of such Borrowing
Base Properties which are categorized as “proved, undeveloped,” “proved, developed, non-producing”
or “proved, developed, producing,” 100% of the consideration received in respect of such sale or
other disposition shall be cash or other Oil and Gas Properties of comparable value and reserve
classification, the consideration received in respect of such sale or other disposition shall be
equal to or greater than the fair market value of the Borrowing Base Property, interest therein or
Subsidiary that is the subject of such sale or other disposition (as reasonably determined by the
board of managers of the General Partner and, if requested by the Administrative Agent, the
Borrower shall deliver a certificate of a Responsible Officer certifying to that effect), if the
aggregate value of all such Borrowing Base Properties, interest therein or Subsidiaries owning
Borrowing Base Properties sold or disposed of exceed seven percent (7%) of the Borrowing Base then
in effect during any period between two (2) successive Scheduled Redetermination Dates (for
purposes of this clause (d) the Effective Date will be deemed to be a Scheduled Redetermination),
then the Borrowing Base shall be reduced effective as set forth in Section 2.07(d) upon
such sale or disposition, by an amount equal to the Borrowing Base value, if any, attributed by the
Administrative Agent (and approved by the Required Lenders) to such Borrowing Base Properties in
the current Borrowing Base based upon the most recently delivered Reserve Report, and if any such
sale or other disposition is of a Subsidiary owning Borrowing Base Properties, such sale or other
disposition shall include all the Equity Interests of such Subsidiary; and

          (e) sales and other dispositions of Properties not regulated by Section 9.12(a)
through (d) having a fair market value not to exceed $5,000,000 during any 12-month period.

     Section 9.13 Environmental Matters. QRE MLP will not, and will not permit any of its
Subsidiaries to, cause or permit any of its Property to be in violation of, or do anything or
permit anything to be done which will subject any such Property to any Remedial Work under any
Environmental Laws, assuming disclosure to the applicable Governmental Authority of all relevant
facts, conditions and circumstances, if any, pertaining to such Property where such violations or
remedial obligations could reasonably be expected to have a Material Adverse Effect.

     Section 9.14 Transactions with Affiliates; Management Fees. QRE MLP will not, and
will not permit any of its Subsidiaries to, enter into any transaction including, without
limitation, any purchase, sale, lease or exchange of Property or the rendering of any service, with
any Affiliate (other than the Guarantors and Wholly-Owned Subsidiaries of the Borrower) (excluding
agreements in effect on the Effective Date, services agreements, managerial agreements, operating
agreements and arrangements with Affiliates relating to future acquisitions) unless such
transactions are not otherwise prohibited under this Agreement and are upon fair and reasonable
terms no less favorable to it than it would obtain in a comparable arm’s length transaction with a
Person not an Affiliate. The Borrower will not, and will not permit any of its Subsidiaries to,
pay management and related fees, but excluding management fees, costs and

79

 

expenses currently permitted as of the Effective Date under organizational documents and
management agreements of the Borrower and its Affiliates, as such agreements and documents may be
amended in the future; provided, that any amendment increasing the management and related
fees shall require the consent of the Administrative Agent, such consent not to be unreasonably
withheld or delayed.

     Section 9.15 Subsidiaries. The Borrower will not, and will not permit any of its
Subsidiaries to, create or acquire any additional Subsidiary unless such Subsidiary is a

Subsidiaries other than Wholly-Owned Subsidiaries.

     Section 9.16 Negative Pledge Agreements; Dividend Restrictions. QRE MLP will not, and
will not permit any of its Subsidiaries to, create, incur, assume or suffer to exist any contract,
agreement or understanding which in any way prohibits or restricts the granting, conveying,
creation or imposition of any Lien on any of its Property in favor of the Administrative Agent and
the Lenders or restricts any Subsidiary from paying dividends or making distributions to the
Borrower or any Guarantor, or which requires the consent of or notice to other Persons in
connection therewith; provided, however, that the preceding restrictions will not apply to
encumbrances or restrictions arising under or by reason of (a) this Agreement or the Security
Instruments, (b) any contract, agreement or understanding creating Liens permitted by Section
9.03(c) or Section 9.03(d) (but only to the extent related to the Property on which
such Liens were created), (c) any leases or licenses or similar contracts as they affect any
Property or Lien subject to a lease or license, (d) customary restrictions and conditions with
respect to the sale or disposition of Property or Equity Interests permitted under Section

require the Borrower or such Subsidiary to deliver, in the aggregate, one percent (1.0%) or more of
the Borrower’s proved reserves (calculated at the Effective Date or the “as of” date of such
certificates, as applicable) at some future time without then or thereafter receiving full payment
therefor.

     Section 9.18 Swap Agreements; Swap Agreement Terminations.

          (a) QRE MLP will not, and will not permit any of its Subsidiaries to, enter into any Swap
Agreements with any Person other than:

80

 

               (i) Swap Agreements in respect of commodities (A) with an Approved Counterparty, (B) with a
tenor not to exceed ten (10) years and (C) the notional volumes for which (when aggregated with
other commodity Swap Agreements then in effect other than basis differential swaps on volumes
already hedged pursuant to other Swap Agreements) do not exceed, as of the date such Swap
Agreement is executed, the greater of (1) 90% of the reasonably anticipated projected production
from proved developed producing reserves constituting the Oil and Gas Properties evaluated in the
most recently delivered Reserve Report for each month during the period during which such Swap
Agreement is in effect for each of crude oil and natural gas, calculated separately and (2) 85% of
forecasted production from total proved reserves constituting Oil and Gas Properties evaluated in
the most recently delivered Reserve Report for two (2) years from the date of determination for
each of crude oil and natural gas, calculated separately and 75% of forecasted production from
total proved reserves constituting Oil and Gas Properties evaluated in the most recently delivered
Reserve Report thereafter for each of crude oil and natural gas, calculated separately (such
amounts computed on a monthly basis) provided that, with respect to any year, maximum notional
volumes under this Section 9.18(a)(i)(C) will be determined using the applicable calculation for
such year regardless of the calculation applicable to the preceding or succeeding year and

               (ii) Swap Agreements in respect of interest rates with an Approved Counterparty, as follows:
(A) Swap Agreements effectively converting interest rates from fixed to floating, the notional
amounts of which (when aggregated with all other Swap Agreements of QRE MLP and its Subsidiaries
then in effect effectively converting interest rates from fixed to floating) do not exceed 50% of
the then outstanding principal amount of the Borrower’s Debt for borrowed money which bears
interest at a fixed rate and (B) Swap Agreements effectively converting interest rates from
floating to fixed, the notional amounts of which (when aggregated with all other Swap Agreements
of QRE MLP and its Subsidiaries then in effect effectively converting interest rates from floating
to fixed) do not exceed 100% of the then outstanding principal amount of the Borrower’s Debt for
borrowed money which bears interest at a floating rate.

          (b) In no event shall any Swap Agreement, other than the Swap Agreements with the Secured
Hedging Providers which are secured by the Security Instruments, contain any requirement, agreement
or covenant for QRE MLP or any of its Subsidiaries to post collateral or margin to secure their
obligations under such Swap Agreement or to cover market exposures.

          (c) QRE MLP shall, and shall require its Subsidiaries to, maintain the hedged positions
established pursuant to Swap Agreements used to calculate the then effective Borrowing Base and
shall, and shall require its Subsidiaries to, neither assign, terminate or unwind any such Swap
Agreements nor sell any Swap Agreements unless the Borrower provides not less than ten (10)
Business Days’ prior written notice of such intent to the Administrative Agent and the Lenders;
provided that if the net effect of such assignment, termination or unwind (when taken
together with any other Swap Agreements executed contemporaneously with the taking of such action)
would have the effect of reducing the economic value supporting the Borrowing Base, then the
Borrowing Base shall be simultaneously reduced in accordance with Section 2.07(e).

81

 

     Section 9.19 Transaction Documents. QRE MLP will not, and will not permit any of its
Subsidiaries to, amend, modify or supplement any of the Transaction Documents if the effect thereof
could reasonably be expected to have a Material Adverse Effect (and provided that the
Borrower promptly furnishes to the Administrative Agent a copy of such amendment, modification or
supplement).

     Section 9.20 Organizational Documents. QRE MLP will not, and will not permit any of
its Subsidiaries to, amend, modify or supplement (or vote to enable, or take any other action to
permit an amendment, modification or supplement of) any Organizational Document of the Borrower or
any Subsidiary in a manner that would be adverse to the Lenders in any material respect.

     Section 9.21 Anti-Terrorism Law; Anti-Money Laundering.

          (a) QRE MLP shall not, and shall not permit any Subsidiary to, directly or indirectly, (i)
knowingly conduct any business or engage in making or receiving any contribution of funds, goods or
services to or for the benefit of any Person described in Section 7.22, (ii) knowingly deal
in, or otherwise engage in any transaction relating to, any Property or interests in Property
blocked pursuant to the Executive Order or any other Anti-Terrorism Law, or (iii) knowingly engage
in or conspire to engage in any transaction that evades or avoids, or has the purpose of evading or
avoiding, or attempts to violate, any of the prohibitions set forth in any Anti-Terrorism Law (and
the General Partner shall deliver to any Lender any certification or other evidence requested from
time to time by such Lender confirming QRE MLP’s and its Subsidiaries’ compliance with this
Section 9.21(a)).

          (b) QRE MLP shall not, and shall not permit any Subsidiary to, cause or permit any of the
funds of QRE MLP, the Borrower or any of its Subsidiary that are used to repay the Loans to be
derived from any unlawful activity with the result that the making of the Loans would be in
violation of any Governmental Regulation.

     Section 9.22 Embargoed Person. QRE MLP shall not, and shall not permit any of its
Subsidiaries to, permit (a) any of the funds or Properties of QRE MLP or any of its Subsidiaries

International Emergency Economic Powers Act, 50 U.S.C. §§ 1701 et seq., The Trading with the Enemy
Act, 50 U.S.C. App. 1 et seq., and any Executive Order or Governmental Regulation promulgated
thereunder, with the result that the investment in QRE MLP or any of its Subsidiaries (whether
directly or indirectly) is prohibited by a Governmental Regulation, or the Loans would be in
violation of a Governmental Regulation, or (ii) the Executive Order, any related enabling
legislation or any other similar Executive Orders or (b) any Embargoed Person to have any direct or
indirect interest, of any nature whatsoever in QRE MLP or any of its Subsidiaries, with the result
that the investment in QRE MLP or any of its Subsidiaries (whether directly or indirectly) is
prohibited by a Governmental Regulation or the Loans are in violation of a Governmental Regulation.

ARTICLE XI

The Agents

     Section 11.01 Appointment; Powers. Each of the Lenders and the Issuing Bank hereby
irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent
to take such actions on its behalf and to exercise such powers as are delegated to the
Administrative Agent by the terms hereof and the other Loan Documents, together with such actions
and powers as are reasonably incidental thereto.

     Section 11.02 Duties and Obligations of Administrative Agent. The Administrative
Agent shall have no duties or obligations except those expressly set forth in the Loan Documents.
Without limiting the generality of the foregoing, the Administrative Agent shall not be subject to
any fiduciary or other implied duties, regardless of whether a Default has occurred and is
continuing (the use of the term “agent” herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law; rather, such term is used
merely as a matter of market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties), the Administrative Agent shall have no duty
to take any discretionary action or exercise any discretionary powers, except as provided in
Section 11.03, and except as expressly set forth herein, the Administrative Agent shall
have no duty to disclose, and shall not be liable for the failure to disclose, any information
relating to the Borrower or any other Obligor that is communicated to or obtained by the bank
serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent
shall be deemed not to have knowledge of any Default unless and until written notice thereof is
given to the Administrative Agent by a Responsible Officer or a Lender, and shall not be
responsible for or have any duty to ascertain or inquire into any statement, warranty or
representation made in or in connection with this Agreement or any other Loan Document, the

86

 

contents of any certificate, report or other document delivered hereunder or under any other
Loan Document or in connection herewith or therewith, the performance or observance of any of the
covenants, agreements or other terms or conditions set forth herein or in any other Loan Document,
the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan
Document or any other agreement, instrument or document, the satisfaction of any condition set
forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly
required to be delivered to the Administrative Agent or as to those conditions precedent expressly
required to be to the Administrative Agent’s satisfaction, the existence, value, perfection or
priority of any collateral security or the financial or other condition of the Borrower and the
other Obligors or any other obligor or guarantor, or any failure by the Borrower or any other
Person (other than itself) to perform any of its obligations hereunder or under any other Loan
Document or the performance or observance of any covenants, agreements or other terms or conditions
set forth herein or therein. For purposes of determining compliance with the conditions specified
in Article VI, each Lender shall be deemed to have consented to, approved or accepted or to
be satisfied with, each document or other matter required thereunder to be consented to or approved
by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received
written notice from such Lender prior to the proposed closing date specifying its objection
thereto.

     Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no
duty to take any discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby or by the other Loan Documents that the
Administrative Agent is required to exercise in writing as directed by the Majority Lenders or the
Required Lenders as applicable (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 2.07(c)(iii) or Section
12.02) and in all cases the Administrative Agent shall be fully justified in failing or
refusing to act hereunder or under any other Loan Documents unless it shall receive written
instructions from the Majority Lenders or the Required Lenders or the Lenders, as applicable, (or
such other number or percentage of the Lenders as shall be necessary under the circumstances as
provided in Section 2.07(c)(iii) or Section 12.02) specifying the action to be
taken and be indemnified to its satisfaction by the Lenders against any and all liability and
expenses which may be incurred by it by reason of taking or continuing to take any such action.
The instructions as aforesaid and any action taken or failure to act pursuant thereto by the
Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is
continuing, then the Administrative Agent shall take such action with respect to such Default as
shall be directed by the requisite Lenders in the written instructions (with indemnities) described
in this Section 11.03, provided that, unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such Default as it shall deem
advisable in the best interests of the Lenders. In no event, however, shall the Administrative
Agent be required to take any action which exposes the Administrative Agent to personal liability
or which is contrary to this Agreement, the Loan Documents or applicable law. If a Default has
occurred and is continuing, neither the Syndication Agent nor any Documentation Agent shall have
any obligation to perform any act in respect thereof. The Administrative Agent shall not be liable
for any action taken or not taken by it with the consent or at the request of the Required Lenders,
the Majority Lenders or the Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 2.07(c)(iii) or Section
12.02), and otherwise the

87

 

Administrative Agent shall not be liable for any action taken or not taken by it hereunder or
under any other Loan Document or under any other document or instrument referred to or provided for
herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE,
except for its own gross negligence or willful misconduct.

     Section 11.04 Reliance by Administrative Agent. The Administrative Agent shall be
entitled to rely upon, and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon
any statement made to it orally or by telephone and believed by it to be made by the proper Person,
and shall not incur any liability for relying thereon except in the case of gross negligence or
willful misconduct by the Administrative Agent. The Administrative Agent may consult with legal
counsel (who may be counsel for the Borrower), independent accountants and other experts selected
by it, and shall not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountants or experts. The Administrative Agent may deem and treat
the payee of any Note as the holder thereof for all purposes hereof unless and until a written
notice of the assignment or transfer thereof permitted hereunder shall have been filed with the
Administrative Agent.

     Section 11.05 Subagents. The Administrative Agent may perform any and all its duties
and exercise its rights and powers by or through any one or more sub-agents appointed by the
Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its
duties and exercise its rights and powers through their respective Related Parties. The
exculpatory provisions of the preceding Sections of this Article XI shall apply to any such
sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall
apply to their respective activities in connection with the syndication of the credit facilities
provided for herein as well as activities as Administrative Agent.

     Section 11.06 Resignation or Removal of Administrative Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided in this Section
11.06, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing
Bank and the Borrower, and the Administrative Agent may be removed at any time with or without
cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall
have the right, with the approval of the Borrower (if no Event of Default exists) or in
consultation with the Borrower (if an Event of Default exists) to appoint a successor. If no
successor shall have been so appointed by the Majority Lenders and shall have accepted such
appointment within thirty (30) days after the retiring Administrative Agent gives notice of its
resignation or removal of the retiring Administrative Agent, then the retiring Administrative Agent
may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which
shall be a bank with an office in the United States of America, or an Affiliate of any such bank.
Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such
successor shall succeed to and become vested with all the rights, powers, privileges and duties of
the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from
its duties and obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After the Administrative Agent’s resignation hereunder,
the provisions of this Article XI and Section 12.03 shall continue in effect

88

 

for the benefit of such retiring Administrative Agent, its sub-agents and their respective
Related Parties in respect of any actions taken or omitted to be taken by any of them while it was
acting as Administrative Agent.

     Section 11.07 Agents as Lenders. Each bank serving as an Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and may exercise the
same as though it were not an Agent, and such bank and its Affiliates may accept deposits from,
lend money to and generally engage in any kind of business with the Borrower, any other Obligor or
Affiliate thereof as if it were not an Agent hereunder.

     Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and
without reliance upon the Administrative Agent, any other Agent or any other Lender and based on
such documents and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and each other Loan Document to which it is a party. Each
Lender also acknowledges that it will, independently and without reliance upon the Administrative
Agent, any other Agent or any other Lender and based on such documents and information as it shall
from time to time deem appropriate, continue to make its own decisions in taking or not taking
action under or based upon this Agreement, any other Loan Document, any related agreement or any
document furnished hereunder or thereunder. The Agents shall not be required to keep themselves
informed as to the performance or observance by the Borrower or any other Obligor of this
Agreement, the Loan Documents or any other document referred to or provided for herein or to
inspect the Properties or books of the Borrower or any other Obligor. Except for notices, reports
and other documents and information expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, no Agent or any Arranger shall have any duty or responsibility to
provide any Lender with any credit or other information concerning the affairs, financial condition
or business of the Borrower (or any of its Affiliates) which may come into the possession of such
Agent or any of its Affiliates. In this regard, each Lender acknowledges that Locke Lord Bissell &
Liddell LLP is acting in this transaction as special counsel to the Administrative Agent only,
except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each
other party hereto will consult with its own legal counsel to the extent that it deems necessary in
connection with the Loan Documents and the matters contemplated therein.

     Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment,
composition or other judicial proceeding relative to the Borrower or any other Obligor, the
Administrative Agent (irrespective of whether the principal of any Loan or other Obligations shall
then be due and payable as herein expressed or by declaration or otherwise and irrespective of
whether the Administrative Agent shall have made any demand on the Borrower or any other Obligor)
shall be entitled and empowered, by intervention in such proceeding or otherwise:

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such
other documents as may be necessary or advisable in order to have the claims of the Lenders and the
Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements
and advances of the Lenders and the Administrative Agent and their

89

 

respective agents and counsel and all other amounts due the Lenders and the Administrative
Agent under Section 12.03) allowed in such judicial proceeding; and

          (b) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender to make such payments to the
Administrative Agent and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its
agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement,
adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the
Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

     Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each
Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any Collateral
that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender
and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the
Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination
statements, assignments or other documents reasonably requested by the Borrower in connection with
any sale or other disposition of Property to the extent such sale or other disposition is permitted
by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents.

     Section 11.11 The Arrangers, the Syndication Agent and the Documentation Agents. The
Arrangers, the Syndication Agent and the Documentation Agents shall have no duties,
responsibilities or liabilities under this Agreement and the other Loan Documents other than their
duties, responsibilities and liabilities in their capacity as Lenders hereunder.

for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed
by certified or registered mail or sent by telecopy, as follows:

               (i) if to the Borrower, to it at c/o QRE GP, LLC, 1401 McKinney, Suite 2400, Houston, Texas

90

 

               (ii) if to the Administrative Agent, to Wells Fargo at 1000 Louisiana Street, 9th Floor,
Houston, Texas 77002, Attention: Douglas McDowell, Telecopy No. (713) 319-1925; and

               (iii) if to any other Lender, to it at its address (or telecopy number) set forth in its

          (b) Notices and other communications to the Lenders hereunder may be delivered or furnished by
electronic communications pursuant to procedures approved by the Administrative Agent;
provided that the foregoing shall not apply to notices pursuant to Article II,
Article III, Article IV and Article V unless otherwise agreed by the
Administrative Agent and the applicable Lender. The Administrative Agent or the Borrower may, in
its discretion, agree to accept notices and other communications to it hereunder by electronic

procedures may be limited to particular notices or communications.

          (c) Any party hereto may change its address or telecopy number for notices and other

     Section 12.02 Waivers; Amendments.

          (a) No failure on the part of the Administrative Agent, any other Agent, the Issuing Bank or
any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any
right, power or privilege, or any abandonment or discontinuance of steps to enforce such right,
power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall
any single or partial exercise of any right, power or privilege under any of the Loan Documents
preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies of the Administrative Agent, any other Agent, the Issuing Bank
and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive
of any rights or remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by any Obligor therefrom shall in
any event be effective unless the same shall be permitted by Section 12.02(b), and then
such waiver or consent shall be effective only in the specific instance and for the purpose for
which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of
a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the
Administrative Agent, any other Agent, any Lender or the Issuing Bank may have had notice or
knowledge of such Default at the time.

          (b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any
provision thereof may be waived, amended or modified except pursuant to an agreement or agreements
in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the
Administrative Agent with the consent of the Majority Lenders; provided that no such
agreement shall (i) increase the Commitment or the Maximum Credit Amount of any Lender without the
written consent of such Lender, (ii) increase the Borrowing Base without the written consent of
each Lender, decrease or maintain the Borrowing Base without the consent

91

 

of the Required Lenders, or modify in any manner Section 2.07 without the consent of
each Lender, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of
interest thereon, or reduce any fees payable hereunder, or reduce any other Obligations hereunder
or under any other Loan Document, without the written consent of each Lender affected thereby, (iv)
postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC
Disbursement, or any interest thereon, or any fees payable hereunder, or any other Obligations
hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such
payment, or postpone or extend the Termination Date without the written consent of each Lender
affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that
would alter the pro rata treatment of Lenders or the pro rata sharing of payments required thereby,
without the written consent of each Lender, (vi) waive or amend Section 3.04(c),
Section 6.01, Section 8.14, Section 8.15, Section 10.02(c),
Section 12.14 or change the definition of the terms “Domestic Subsidiary”,
“Foreign Subsidiary” or “Subsidiary”, without the written consent of each Lender,
(vii) release any Obligor from its obligations under the Guaranty Agreement (except as set forth in
the Guaranty Agreement), release any of the Collateral (other than as provided in Section
11.10), or reduce the percentage set forth in Section 8.15(a) to less than 80%, without
the written consent of each Lender and each Person that is adversely affected thereby, including a
Secured Hedging Provider that is not a Lender or an Affiliate of a Lender at the time of such
waiver or amendment, or (viii) change any of the provisions of this Section 12.02(b) or the
definitions of “Majority Lenders”, “Required Lenders” or “Supermajority
Lenders” or any other provision hereof specifying the number or percentage of Lenders required
to waive, amend or modify any rights hereunder or under any other Loan Documents or make any
determination or grant any consent hereunder or any other Loan Documents, without the written
consent of each Lender and each Person that is adversely affected thereby, including a Secured
Hedging Provider that is not a Lender or an Affiliate of a Lender at the time of such waiver or
amendment; provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of the Administrative Agent, any other Agent or the Issuing Bank hereunder or
under any other Loan Document without the prior written consent of the Administrative Agent, such
other Agent or the Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement
to Schedule 7.13 (Subsidiaries and Partnerships) shall be effective simply by delivering to
the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the
Administrative Agent will promptly deliver a copy thereof to the Lenders and Annex I may be
amended upon delivery by the Administrative Agent of a revised Annex I in accordance with
Section 12.04(b)(iv).

     Section 12.03 Expenses, Indemnity; Damage Waiver.

          (a) The Borrower shall pay, from time to time and on demand, all reasonable and documented
out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including, without
limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants

facilities provided for herein, the preparation, negotiation, execution, delivery and
administration (both before and after the execution hereof and including advice of counsel to the
Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with

92

 

and any amendments, modifications or waivers of or consents related to the provisions hereof
or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated),
all costs, expenses, Taxes, assessments and other charges incurred by any Agent or any Lender in
connection with any filing, registration, recording or perfection of any security interest
contemplated by this Agreement or any Security Instrument or any other document referred to
therein, all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the
issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment
thereunder, all out-of-pocket expenses incurred by any Agent, the Issuing Bank or any Lender,
including the fees, charges and disbursements of any counsel for any Agent, the Issuing Bank or any
Lender, in connection with the enforcement or protection of its rights in connection with this
Agreement or any other Loan Document, including its rights under this Section 12.03, or in
connection with the Loans made or Letters of Credit issued hereunder, including, without
limitation, all such out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans or Letters of Credit.

          (b) THE BORROWER AND EACH GUARANTOR SHALL INDEMNIFY EACH AGENT, EACH ARRANGER, THE ISSUING
BANK AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON
BEING CALLED AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL
LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE FEES, CHARGES AND
DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE
ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF THE EXECUTION OR DELIVERY OF THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT (OTHER THAN EXPENSES IN CONNECTION WITH THE EXECUTION AND DELIVERY OF
THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS DATED OF EVEN DATE HEREWITH, WHICH EXPENSES SHALL ONLY
BE PAID BY THE BORROWER TO THE EXTENT PROVIDED IN SECTION 12.03(a)) OR ANY AGREEMENT OR INSTRUMENT
CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER
LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, THE FAILURE OF THE BORROWER OR ANY
OTHER OBLIGOR TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY
GOVERNMENTAL REQUIREMENT, ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR
COVENANT OF THE BORROWER OR ANY OTHER OBLIGOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY
INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, ANY LOAN OR LETTER OF
CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, ANY REFUSAL BY THE
ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN
CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, OR THE
PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR
OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, ANY OTHER ASPECT
OF

93

 

THE LOAN DOCUMENTS, THE OPERATIONS OF THE BUSINESS OF THE BORROWER, THE OBLIGORS AND THEIR
AFFILIATES BY THE BORROWER, THE OTHER OBLIGORS AND THEIR AFFILIATES, ANY ASSERTION THAT THE
LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS,

PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR
CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN

94

 

          (c) To the extent that the Borrower fails to pay any amount required to be paid by it to any
Agent, any Arranger or the Issuing Bank under Section 12.03(a) or (b), each Lender
severally agrees to pay to such Agent, such Arranger or the Issuing Bank, as the case may be, such
Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense
or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed
expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was
incurred by or asserted against such Agent, such Arranger or the Issuing Bank in its capacity as
such.

          (d) To the extent permitted by applicable law, neither the Borrower nor any other Obligor
shall assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability,
for special, indirect, consequential or punitive damages (as opposed to direct or actual damages)
arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or
any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of
Credit or the use of the proceeds thereof.

          (e) All amounts due under this Section 12.03 shall be payable not later than five (5)
days after written demand therefor.

     Section 12.04 Successors and Assigns.

          (a) Successors and Assigns Generally. The provisions of this Agreement 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 the Issuing Bank that issues any Letter of
Credit), except that the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and void) and no Lender
may assign or otherwise transfer its rights or obligations hereunder except in accordance with this
Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective successors and assigns
permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit),
Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly
contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and
the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

          (b) Assignments by Lenders.

               (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may
assign to one or more assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment and the Loans at the time owing to it)
with the prior written consent (such consent not to be unreasonably withheld) of:

          (A) the Borrower, provided that no consent of the Borrower shall be required for an
assignment (x) to a Lender, an Affiliate of a Lender, or an Approved Fund or (y) if an Event of
Default has occurred and is continuing; and

95

 

          (B) the Administrative Agent, provided that no consent of the Administrative Agent
shall be required for an assignment to an assignee that is a Lender immediately prior to giving
effect to such assignment.

               (ii) Assignments shall be subject to the following additional conditions:

          (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an
assignment of the entire remaining amount of the assigning Lender’s Commitment, the amount of the
Commitment of the (x) assigning Lender subject to each such assignment (determined as of the date
the Assignment and Assumption with respect to such assignment is delivered to the Administrative
Agent) shall not be less than $5,000,000 and (y) assignee Lender subject to each such assignment
(determined as of the date the Assignment and Assumption with respect to such assignment is
delivered to the Administrative Agent) shall be at least $5,000,000, in each case unless each of
the Borrower and the Administrative Agent otherwise consent, provided that no such consent
of the Borrower shall be required if an Event of Default has occurred and is continuing;

          (B) each partial assignment shall be made as an assignment of a proportionate part of all the
assigning Lender’s rights and obligations under this Agreement;

          (C) the parties to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Assumption, together with a processing and recordation fee of $3,500; and

          (D) the assignee, if it is not currently a Lender, shall deliver to the Administrative Agent
an Administrative Questionnaire.

               (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from
and after the effective date specified in each Assignment and Assumption the assignee thereunder
shall be a party hereto and, to the extent of the interest assigned by such Assignment and
Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption,
be released from its obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender’s rights and obligations under this Agreement,
such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of
Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale
by such Lender of a participation in such rights and obligations in accordance with Section
12.04(c).

               (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall
maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the Maximum Credit
Amount of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant
to the terms hereof from time to time (the “Register”). The

96

 

entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the
Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant
to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding
notice to the contrary. The Register shall be available for inspection by the Borrower, the
Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior
notice. In connection with any changes to the Register, if necessary, the Administrative Agent
will reflect the revisions on Annex I and forward a copy of such revised Annex I
to the Borrower, the Issuing Bank and each Lender.

               (v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning
Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee
is already a Lender), the processing and recordation fee referred to in this Section
12.04(b) and any written consent to such assignment required by this Section 12.04(b),
the Administrative Agent shall accept such Assignment and Assumption and record the information
contained therein in the Register. No assignment shall be effective for purposes of this
Agreement unless it has been recorded in the Register as provided in this Section
12.04(b).

          (c) Participations.

               (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the
Issuing Bank, sell participations to one or more banks or other entities (a “Participant”)
in all or a portion of such Lender’s rights and obligations under this Agreement (including all or
a portion of its Commitment and the Loans owing to it); provided that such Lender’s
obligations under this Agreement shall remain unchanged, such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and the Borrower,
the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this Agreement; provided
that such agreement or instrument may provide that such Lender will not, without the consent of
the Participant, agree to any amendment, modification or waiver described in the proviso to
Section 12.02 that affects such Participant. In addition such agreement must provide that
the Participant be bound by the provisions of Section 12.03. Subject to Section
12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of
Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it
were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b).
To the extent permitted by law, each Participant also shall be entitled to the benefits of
Section 12.08 as though it were a Lender, provided such Participant agrees to be subject
to Section 4.01(c) as though it were a Lender.

               (ii) A Participant shall not be entitled to receive any greater payment under Section
5.01 or Section 5.03 than the applicable Lender would have been entitled to receive
with respect to the participation sold to such Participant, unless the sale of the participation
to such Participant is made with the Borrower’s prior written consent. A Participant that would
be a Foreign Lender if it were a Lender shall not be entitled to the

97

 

benefits of Section 5.03 unless the Borrower is notified of the participation sold to
such Participant and such Participant agrees, for the benefit of the Borrower, to comply with
Section 5.03(e) as though it were a Lender.

          (d) Certain Pledges. Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations of such Lender,
including, without limitation, any pledge or assignment to secure obligations to a Federal Reserve
Bank or central bank having jurisdiction over such Lender, and this Section 12.04(d) shall
not apply to any such pledge or assignment of a security interest; provided that no such
pledge or assignment of a security interest shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     Section 12.05 Survival; Revival; Reinstatement.

          (a) All covenants, agreements, representations and warranties made by the Borrower or any
Obligor herein and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon
by the other parties hereto and shall survive the execution and delivery of this Agreement and the
making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by
any such other party or on its behalf and notwithstanding that the Administrative Agent, any other
Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and shall continue in full
force and effect as long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is
outstanding and so long as the Commitments have not expired or terminated. The provisions of
Section 5.01, Section 5.02, Section 5.03, and Section 12.03 and
Article XI shall survive and remain in full force and effect regardless of the consummation
of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination
of the Letters of Credit and the Commitments or the termination of this Agreement, any other Loan
Document or any provision hereof or thereof.

          (b) To the extent that any payments on the Obligations or proceeds of any collateral are
subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be
repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law,
common law or equitable cause, then to such extent, the Obligations so satisfied shall be revived
and continue as if such payment or proceeds had not been received and the Administrative Agent’s
and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and
each Loan Document shall continue in full force and effect. In such event, each Loan Document
shall be automatically reinstated and the Borrower and each other Obligor shall take such action as
may be reasonably requested by the Administrative Agent and the Lenders to effect such
reinstatement.

     Section 12.06 Counterparts; Integration; Effectiveness.

          (a) This Agreement 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.

98

 

          (b) This Agreement, the other Loan Documents and any separate letter agreements with respect
to fees payable to the Administrative Agent constitute the entire contract among the parties
relating to the subject matter hereof and thereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND
MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

          (c) Except as provided in Section 6.01, this Agreement shall become effective when it
shall have been executed by the Administrative Agent and when the Administrative Agent shall have
received counterparts hereof which, when taken together, bear the signatures of each of the other
parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart of a signature
page of this Agreement by telecopy or as an attachment to an email shall be effective as delivery
of a manually executed counterpart of this Agreement.

     Section 12.07 Severability. Any provision of this Agreement or any other Loan
Document 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 or
thereof; and the invalidity of a particular provision in a particular jurisdiction shall not
invalidate such provision in any other jurisdiction.

     Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be
continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time
to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general
or special, time or demand, provisional or final) at any time held and other obligations (of
whatsoever kind, including, without limitations obligations under Swap Agreements) at any time
owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any other
Obligor against any of and all the obligations of the Borrower or any other Obligor owed to such
Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of
whether or not such Lender shall have made any demand under this Agreement or any other Loan
Document and although such obligations may be unmatured. The rights of each Lender under this
Section 12.08 are in addition to other rights and remedies (including other rights of
setoff) which such Lender or its Affiliates may have.

     Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

          (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE
COURTS OF THE STATE OF NEW

99

 

YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY
EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT
PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF
THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT
LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS,
WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH
RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A
PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

          (c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED
MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER
ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), AND
TO THE EXTENT PERMITTED UNDER APPLICABLE LAW SUCH SERVICE SHALL BECOME EFFECTIVE THIRTY (30) DAYS
AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO
SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION.

          (d) EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL,
EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL
DAMAGES; CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR ANY PARTY
HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT
OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION
12.09.

     Section 12.10 Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and shall not affect
the construction of, or be taken into consideration in interpreting, this Agreement.

100

 

     Section 12.11 Confidentiality. Each of the Administrative Agent, the Issuing Bank and
the Lenders agrees to maintain the confidentiality of the Information (as defined below), except
that Information may be disclosed to its and its Affiliates’ directors, officers, employees and
agents, including accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), to the extent requested by any
regulatory authority or in connection with a pledge or assignment permitted by Section
12.04(d), to the extent required by applicable laws or regulations or by any subpoena or
similar legal process, to any other party to this Agreement or any other Loan Document, in
connection with the exercise of any remedies hereunder or under any other Loan Document or any
suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement
of rights hereunder or thereunder, subject to an agreement containing provisions substantially the
same as those of this Section 12.11, to any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations under this Agreement or
any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the
Borrower and its obligations, with the consent of the Borrower or to the extent such Information
becomes publicly available other than as a result of a breach of this Section 12.11 or
becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential
basis from a source other than the Borrower. For the purposes of this Section 12.11,
“Information” means all information received from the Borrower or any other Obligor
relating to the Borrower or any other Obligor and their businesses, other than any such information
that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential
basis prior to disclosure by the Borrower or any other Obligor; provided that, in the case
of information received from the Borrower or any Obligor after the date hereof, such information is
clearly identified at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section 12.11 shall be considered to
have complied with its obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to its own
confidential information.

     Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto
that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the
transactions contemplated hereby would be usurious as to any Lender under laws applicable to it
(including the laws of the United States of America and the State of Texas or any other
jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other
provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as security for the
Loans, it is agreed as follows: the aggregate of all consideration which constitutes interest
under law applicable to any Lender that is contracted for, taken, reserved, charged or received by
such Lender under any of the Loan Documents or agreements or otherwise in connection with the Loans
shall under no circumstances exceed the maximum amount allowed by such applicable law, and any
excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on
the principal amount of the Obligations (or, to the extent that the principal amount of the
Obligations shall have been or would thereby be paid in full, refunded by such Lender to the
Borrower); and in the event that the maturity of the Loans is accelerated by reason of an election
of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in
the event of any required or permitted prepayment, then such consideration that

101

 

constitutes interest under law applicable to any Lender may never include more than the
maximum amount allowed by such applicable law, and excess interest, if any, provided for in this
Agreement or otherwise shall be canceled automatically by such Lender as of the date of such
acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the
principal amount of the Obligations (or, to the extent that the principal amount of the Obligations
shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All
sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due
hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated,
allocated and spread throughout the stated term of the Loans evidenced by the Notes until payment
in full so that the rate or amount of interest on account of any Loans hereunder does not exceed
the maximum amount allowed by such applicable law. If at any time and from time to time (i) the
amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate
applicable to such Lender pursuant to this Section 12.12 and (ii) in respect of any
subsequent interest computation period the amount of interest otherwise payable to such Lender
would be less than the amount of interest payable to such Lender computed at the Highest Lawful
Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of
such subsequent interest computation period shall continue to be computed at the Highest Lawful
Rate applicable to such Lender until the total amount of interest payable to such Lender shall
equal the total amount of interest which would have been payable to such Lender if the total amount
of interest had been computed without giving effect to this Section 12.12.

     Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES
THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS
CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT
IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE
TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL
COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF
THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY
HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY
EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY
HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

     Section 12.14 Collateral Matters; Swap Agreements; Treasury Management Agreements.
The benefit of the Security Instruments and of the provisions of this Agreement relating to any
Collateral securing the Obligations shall also extend to and be available to Secured Hedging
Providers and the Secured Treasury Management Counterparties on a pro rata basis (subject to

102

 

the priorities set out in Section 10.02(c)) in respect of any Obligations of the
Borrower or any other Obligor which arises under any such Swap Agreement or Treasury Management
Agreement. No Lender or any Affiliate of a Lender shall have any voting rights under any Loan
Document as a result of the existence of obligations owed to it under any such Swap Agreements or
Treasury Management Agreements. Each Lender, on behalf of itself and its Affiliates who are
Secured Hedging Providers, and each Secured Hedging Provider, by accepting the benefits of the
Collateral, hereby agrees that the Obligors may grant security interests, covering all rights of
the Obligors in Swap Agreements with any Lender or Secured Hedging Provider, to the Administrative
Agent under the Security Instruments to secure the Obligations, notwithstanding any restriction on
such security interests under any Swap Agreement or Treasury Management Agreement.

     Section 12.15 No Third Party Beneficiaries. This Agreement, the other Loan Documents,
and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or
extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person
(including, without limitation, any other Obligor, any obligor, contractor, subcontractor, supplier
or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other
Loan Document against the Administrative Agent, any other Agent, the Issuing Bank or any Lender for
any reason whatsoever. There are no third party beneficiaries under the Loan Documents.

     Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies the General
Partner, the Borrower and each other Obligor that pursuant to the requirements of the Patriot Act,
it is required to obtain, verify and record information that identifies the General Partner, the
Borrower and each other Obligor, which information includes the name and address of each such
Person and other information that will allow such Lender to identify each such Person in accordance
with the Patriot Act.

     Section 12.17 No Fiduciary Duty. Each Lender and its respective Affiliates
(collectively, solely for purposes of this Section 12.18, the “Lenders”) may have
economic interests that conflict with those of the Obligors. Each Obligor agrees that nothing in
any Loan Document, any Hedging Agreement with any Secured Hedging Provider or any Treasury
Management Agreement will be deemed to create an advisory, fiduciary or agency relationship between
Lenders and the Obligors, their partners or their Affiliates. Each Obligor acknowledges and agrees
that (a) the transactions with Lenders contemplated by the Loan Documents, the Hedging Agreements
with Secured Hedging Providers and the Treasury Management Agreements are arm’s-length commercial
transactions between Lenders, on the one hand, and the applicable Obligors, on the other, (b) in
connection therewith and with the process leading to such transactions each Lender is acting solely
as a principal and not the agent or fiduciary of any Obligor, or of any Obligor’s management,
partners, creditors or other Affiliates, (c) no Lender has assumed a fiduciary responsibility in
favor of any Obligor with respect to the transactions with Lenders contemplated by the Loan
Documents, any Hedging Agreement or any Treasury Management Agreements or the process leading
thereto (irrespective of whether any Lender or any of its Affiliates has advised or is currently
advising any Obligor on other matters) and (d) such Obligor has consulted its own legal and
financial advisors to the extent it deemed appropriate. Each Obligor further acknowledges and
agrees that it is responsible for making its own independent judgment with respect to such
transactions and the process leading thereto.

103

 

Each Obligor agrees that it will not claim that any Lender owes a fiduciary duty to such
Obligor in connection with the Loan Documents, any Hedging Agreement or any Treasury Management
Agreement or the process leading thereto.
