From: Gideon Wertheizer, CEO

Re: 2010 Incentive Plan

This document outlines your Incentive Plan for 2010. The rules and guidelines for the plan are
contained herein.

	 	1.	 	Compensation Package: Your compensation package is made up of a base salary and an
Incentive Bonus (IB) target. The IB provides reward for successful performance and is
based upon your performance to your assigned annual quota, Corporate Quarterly Revenue
Target (CQRT) and Strategic Accounts (SA) deals.
	 
	 	 	 	While the Quota is based upon annual target, the IB payment period is quarterly. Payments
are calculated on a quarterly basis, against your annual quota target, based on bookings
that has been invoiced and recognized as revenue by the Company, and paid after the end of
the respective quarter as soon as is practically possible.

	 	a.	 	Company Revenue Target (CRT)           $*

	 	i.	 	Revenue-Based Incentive Target       $115,000
	 
	 	ii.	 	Commission Rat: *%
	 
	 	iii.	 	Commission Multiplier: The plan include multipliers
(Commission Multipliers), as shown in the table below. The Commission
Multiplier to be used in the quarterly Commission Calculation will be
based on your percent of cumulative Quota and achievement

	 	 	 	 	 
	Percent of Cumulative Quota	 	Commission Multiplier to be
	Achievement	 	Applied
	From 0 to 100%

	 	 	1.0	 
	From 100%

	 	 	1.5	 

	 	b.	 	Corporate Quarterly Revenue Target (CQRT): An additional bonus of
$5,000 will be paid for each of the following quarterly revenue targets if
achieved.

	 	i.	 	Q1          $*
	 
	 	ii.	 	Q2          $*
	 
	 	iii.	 	Q3          $*
	 
	 	iv.	 	Q4          $*

	 	c.	 	Strategic Account (SA) Bonus- An additional bonus of $5,000 will be
paid for each deal that exceeds $1M. (not including prepaid royalties) with
the following companies: *. Payments are calculated on an annual basis, based on
bookings that have been invoiced and recognized as revenue by the Company, and paid
as is practically possible.

 

 

 

The total bonus payment due to SA deals will be capped at $20,000 as long as annual
revenue achieved is below the CRT. The cap for SA bonus will be removed once annual
revenue achieved exceeds the CRT.

	 	2.	 	Effective date/terms: This plan is effective for January 1st, 2010 through
December 31st 2010, unless if modified in writing by the CEO. This plan
supersedes all prior commission plan. Management reserves the right to make any changes to
the sales incentive plan at any time.
	 
	 	3.	 	Plan Eligibility: This plan is applied to full time sales personnel. If you resign,
terminate, or cease to be an employee of the company, you will be entitled to IB on any
revenue amount invoiced up to the date of termination.

I have read and understand the 2010 Incentive Compensation Plan. I have received a copy of the Plan
for my record. I accept the terms and conditions of the Plan as outlined above and agree that my
compensation will be determined according to these terms and conditions.

Financial Statements delivered pursuant to Section 7.04(a)(i) except for changes in which
Borrower’s independent certified public accountants concur and which are disclosed to
Administrative Agent on the next date on which financial statements are required to be delivered to
the Lenders pursuant to Section 8.01(a); provided that, unless the Borrower and the
Majority Lenders shall otherwise agree in writing, no such change shall modify or affect the manner
in which compliance with the covenants contained herein is computed such that all such computations
shall be conducted utilizing financial information presented consistently with prior periods.

ARTICLE II

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 (a) such Lender’s Credit Exposure exceeding such Lender’s
Commitment or (b) the total 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 $1,000,000 and not less than $5,000,000. At the time that each ABR
Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of
$500,000 and not less than $2,500,000; 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.

          (d) Notes. Any Lender may request that Loans made by it be evidenced by a single
promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a
promissory note payable to such Lender in substantially the form of Exhibit A, dated, in
the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this
Agreement and (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.
If any Lender’s Maximum Credit Amount is decreased for any reason (whether pursuant to Section
2.06, Section 12.04(b) or otherwise), the Borrower shall upon request deliver or cause
to be delivered on the effective date of such decrease, a new Note payable to any Lender who
requested a Note hereunder in a principal amount equal to its Maximum Credit Amount after giving
effect to such decrease, and otherwise duly completed, and such Lender agrees to promptly
thereafter return the previously issued Note held by such Lender marked canceled or otherwise
similarly defaced. The date, amount, Type, interest rate and, if applicable, Interest Period of
each Loan made by each Lender that receives a Note, 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 or by written Borrowing Request in
substantially the form of Exhibit B and signed by the Borrower (a “written Borrowing
Request”): (a) in the case of a Eurodollar Borrowing, not later than 2:00 p.m., New York, New
York time,

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

25

 

three (3) Business Days before the date of the proposed Borrowing or (b) in the case of
an ABR Borrowing, not later than 1:00 p.m., New York, New York 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 telephonic and written Borrowing Request shall be irrevocable and each telephonic
Borrowing Request shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent of a written Borrowing Request. 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;

               (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable
thereto, which shall be a period contemplated by the definition of the term “Interest
Period”;

               (v) the amount of the then effective Borrowing Base, the current total Credit Exposures
(without regard to the requested Borrowing) and the pro forma total Credit Exposures (giving effect
to the requested Borrowing); and

               (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.

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 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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

26

 

each such portion shall be considered a separate Borrowing. This Section 2.04 shall not apply to Swingline
Borrowings, which may not be converted or continued.

          (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 or by a
written Interest Election Request in substantially the form of Exhibit C and signed by the
Borrower (a “written Interest Election Request”) 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
telephonic and written Interest Election Request shall be irrevocable and each telephonic Interest
Election Request shall be confirmed promptly by hand delivery or telecopy to the Administrative
Agent.

          (c) Information in Interest Election Requests. Each telephonic and written Interest
Election Request shall specify the following information in compliance with Section 2.02:

               (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

               (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: (i) 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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

27

 

Borrowing shall be ineffective) and (ii) 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,
New York time, to the account of the Administrative Agent most recently designated by it for such
purpose by notice to the Lenders; provided that Swingline Loans shall be made by the time
specified in Section 2.09(c). The Administrative Agent will make such Loans available to
the Borrower by promptly crediting or wire transferring the amounts so received, in like funds, to
one or more accounts 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 that
made such LC Disbursement.

          (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 payment to the Administrative Agent, at
(i) 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 (ii) 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 Changes in the 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 (A) 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 $5,000,000 and
(B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts if, after
giving effect to any concurrent prepayment of the

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

28

 

Loans in accordance with Section 3.04(c), the total 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. 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, the amount of the Borrowing Base shall be
$260,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further
adjustments from time to time pursuant to Section 8.13(d) or Section 9.12.

          (b) Scheduled and Interim Redeterminations.

               (i) 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 Agents, each
Issuing Bank and the Lenders on April 1st and October 1st of each year, commencing with October 1,
2010.

               (ii) The Administrative Agent may, at the direction of the Required Lenders, by notifying the
Borrower thereof, (A) one time during any six-month period (not counting any redetermination
pursuant clause (B) hereof), and (B) at any time upon the issuance of Debt by any Loan Party
pursuant to Section 9.02(f), elect to cause the Borrowing Base to be redetermined between
Scheduled Redeterminations in accordance with this Section 2.07.

               (iii) The Borrower may elect to redetermine the Borrowing Base in connection with any
acquisition by any Loan Party of proved Oil and Gas Properties or any Person owning proved Oil and
Gas Properties (in each such case, if the fair market value of such proved Oil and Gas Properties
or such Person is in excess of $10,000,000) permitted hereunder in accordance with this Section
2.07; provided that such redetermination of the Borrowing Base shall not occur more
than twice between Scheduled Redeterminations.

          (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, in the case of a Scheduled Redetermination, pursuant to
Section 8.12(a) and (c), and, in the case of an

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

29

 

Interim Redetermination, pursuant to Section 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 Administrative Agent or 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 good faith, 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 proved Oil and Gas Properties as described in the Engineering Reports and the existence of
any other Debt) as the Administrative Agent deems appropriate in its sole discretion and consistent
with its normal oil and gas lending criteria as it exists at the particular time. In no event shall
the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts.

               (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
Section 8.12(a) and (c) in a timely and complete manner, then on or before March
15th and September 15th 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 Section 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 have
had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with
Section 2.07(c)(i), and in any event within fifteen (15) days after the Administrative
Agent has received the required Engineering Reports; 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 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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

30

 

or deemed to have approved, as aforesaid, then the Administrative Agent shall (A) notify
the Borrower of the Proposed Borrowing Base and which Lenders have not approved or been deemed to
have approved of the Proposed Borrowing Base and (B) poll the Lenders to ascertain the highest
Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required Lenders
for purposes of this Section 2.07 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), 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 Agents, each 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 Section
8.12(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, 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 Section 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, on the Business Day next succeeding delivery
of such notice.

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

     Section 2.08 Letters of Credit.

          (a) General. The Loan Parties, the Administrative Agent, the Issuing Bank and the
Lenders agree that all Existing Letters of Credit shall be deemed to be issued under this Agreement
as of the Effective Date and shall constitute Letters of Credit hereunder for all purposes (except
that the Issuing Bank’s standard issuance fee shall not be payable on such deemed issuance).
Subject to the terms and conditions set forth herein, the Borrower may request any Issuing Bank to
issue Letters of Credit in dollars for its own account or for the account of any Loan Party, in a
form reasonably acceptable to the Administrative Agent and such Issuing Bank, at any time and from
time to time during the Availability Period. In the event of any inconsistency between the terms
and conditions of this Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by the Borrower to, or entered into by the Borrower with,
an Issuing Bank relating to any Letter of Credit, 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 any 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 outstanding Letter of Credit
issued by such Issuing Bank 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,
the current total 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 Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment,
renewal or extension of an outstanding Letter of Credit). If requested by any Issuing Bank, the
Borrower shall submit a letter of credit application on such Issuing Bank’s standard form in
connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended,
renewed or extended only if (and with respect to each notice provided by the Borrower above and any
issuance, amendment, renewal or extension of each Letter of Credit, the Borrower shall be deemed to
represent and warrant that), after giving effect to such issuance, amendment, renewal or extension
(A) the LC Exposure shall not exceed the LC Commitment and (vii) the total Credit Exposures shall
not exceed the total Commitments (i.e. the lesser of the Aggregate Maximum Credit Amounts and the
then effective Borrowing Base).

          (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of
business on the earliest of (i) the date requested by the Borrower, (ii) the date one year after
the date of the issuance of such Letter of Credit (or, in the case of any renewal, which renewal
may be provided for in the initial Letter of Credit, or extension thereof, one year after such
renewal or extension) and (iii) the date that is five (5) Business Days prior to the Maturity Date.

          (d) Participations. By the issuance of a Letter of Credit (or an amendment to an
existing Letter of Credit increasing the amount thereof) and without any further action on the part
of the Issuing Bank that issues such Letter of Credit or the Lenders, each Issuing Bank that issues
a Letter of Credit hereunder hereby grants to each Lender, and each Lender hereby acquires from
such 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 any Issuing Bank that
issues a Letter of Credit hereunder, such Lender’s Applicable Percentage of each LC Disbursement
made by such 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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

32

 

amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default 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 any Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit issued by such Issuing Bank, the Borrower shall reimburse such LC Disbursement by
paying to the Administrative Agent an amount equal to such LC Disbursement not later than 2:00
p.m., New York, New York time, on the date that such LC Disbursement is made, if the Borrower shall
have received notice of such LC Disbursement prior to 12:00 noon, New York, New York 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 2:00 p.m., New York, New York time, on the Business Day immediately following
the day that the Borrower receives such notice; provided that if such LC Disbursement is
not paid by such time, 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 (or, if such amount is less than $1,000,000, a
Swingline Loan) 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 (or Swingline
Loan). 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 with respect to Loans
made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment
obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank
that issued such Letter of Credit 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
that issued such Letter of Credit or, to the extent that Lenders have made payments pursuant to
this Section 2.08(e) to reimburse such Issuing Bank, then to such Lenders and such Issuing
Bank as their interests may appear. Any payment made by a Lender pursuant to this Section
2.08(e) to reimburse any Issuing Bank for any LC Disbursement (other than the funding of ABR
Loans or Swingline 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 (i) 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, (ii) 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, (iii) payment by
any Issuing Bank under a Letter of Credit issued by such Issuing Bank 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 (iv) 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 any 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 any Issuing Bank;
provided that the foregoing shall not be construed to excuse any 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 such 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 expressly agree that, in the absence of gross negligence or
willful misconduct on the part of any Issuing Bank (as finally determined by a court of competent
jurisdiction), such 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 that issued such
Letter of Credit 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. Each Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of
Credit issued by such Issuing Bank. Such Issuing Bank shall promptly notify the Administrative
Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether
such 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 such Issuing Bank and the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. If any Issuing Bank shall make any LC Disbursement, then, until
the Borrower shall have reimbursed such 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 such
Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant
to Section 2.08(e) to reimburse such Issuing Bank shall be for the account of such Lender
to the extent of such payment.

          (i) Replacement of an Issuing Bank. Any Issuing Bank may be replaced or resign at any
time by written agreement among the Borrower, the Administrative Agent, such

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

34

 

resigning or replaced Issuing Bank and, in the case of a replacement, the successor Issuing
Bank. The Administrative Agent shall notify the Lenders of any such resignation or replacement of
an Issuing Bank. At the time any such resignation or replacement shall become effective, the
Borrower shall pay all unpaid fees accrued for the account of the resigning or replaced Issuing
Bank pursuant to Section 3.05(b). In the case of the replacement of an Issuing Bank, from
and after the effective date of such replacement, (i) the successor Issuing Bank shall have all the
rights and obligations of the replaced Issuing Bank under this Agreement with respect to Letters of
Credit to be issued thereafter and (ii) 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 resignation or replacement of an
Issuing Bank hereunder, the resigning or replaced Issuing Bank shall remain a party hereto and
shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with
respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not
be required to issue additional Letters of Credit.

          (j) Cash Collateralization. If (i) 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(i), or (ii) the Borrower is
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 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 with respect to the Borrower or any
Restricted Subsidiary of the Borrower described in Section 10.01(h) or Section
10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of each
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(i) 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 of its Subsidiaries may now or hereafter have against any such
beneficiary, any 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 Guarantor’s obligations under this Agreement and the other Loan Documents in
a “securities account” (within the meaning of Article 8 of the Uniform

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

35

 

Commercial Code in effect from time to time in the State of New York, the “UCC”) over
which the Administrative Agent shall have “control” (within the meaning of the UCC).
Notwithstanding the foregoing, the Borrower may direct the Administrative Agent and the “securities
intermediary” (within the meaning of the UCC) to invest amounts credited to the securities account,
at the Borrower’s risk and expense, in Investments described in Section 9.05(c) through
(g). 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 Swingline
Lender for Swingline Loans for which it has not been repaid, and reimburse, on a pro rata basis,
each 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 Guarantors 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 (3) Business Days after all Events of
Default have been cured or waived.

          (k) Existing Letters of Credit. If Wells Fargo ceases to be a Lender during a time
when it has one or more Letters of Credit outstanding that it has issued hereunder, each such
Letter of Credit shall continue to be a Letter of Credit hereunder and Wells Fargo shall have all
the rights, remedies, powers and privileges of an Issuing Bank hereunder (including, without
limitation, the right to be reimbursed for any drawing hereunder) with respect to each such
existing Letter of Credit until such time as each such Letter of Credit expires, is drawn and fully
reimbursed or is renewed by another Letter of Credit issued hereunder by another Issuing Bank.

     Section 2.09 Swingline Loans

          (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make
Swingline Loans to the Borrower from time to time during the Availability Period, in an aggregate
principal amount at any time outstanding that will not result in (i) the aggregate principal amount
of outstanding Swingline Loans exceeding $15,000,000 or (ii) the total Credit Exposures exceeding
the total Commitments; provided that the Swingline Lender shall not be required to make a
Swingline Loan to refinance an outstanding Swingline Loan. The Borrower shall pay to the Swingline
Lender, for the account of each Lender, the outstanding aggregate principal and accrued and unpaid
interest under each Swingline Loan no later than five (5) Business Days following such Swingline
Borrowing. Within the foregoing limits and subject to the terms and conditions set forth herein,
the Borrower may borrow, prepay and reborrow Swingline Loans.

          (b) To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such
request by telephone (confirmed by telecopy), not later than 2:00 p.m., New York,
New York time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable
and shall specify the requested date (which shall be a Business Day) and amount of the requested
Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such
notice received from the Borrower. The Swingline Lender shall make each Swingline Loan

Second Amended & Restated Credit Agreement

36

 

available to
the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline
Lender by 3:00 p.m., New York, New York time, on the requested date of such Swingline Loan.

          (c) The Swingline Lender may by written notice given to the Administrative Agent not later
than 2:00 p.m., New York, New York time, on any Business Day require the Lenders to acquire
participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such
notice shall specify the aggregate amount of Swingline Loans in which Lenders will participate.
Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each
Lender, specifying in such notice such Lender’s Applicable Percentage of such Swingline Loan or
Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided
above, to promptly pay to the Administrative Agent, for the account of the Swingline Lender, such
Lender’s Applicable Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees
that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is
absolute and unconditional and shall not be affected by any circumstance whatsoever, including the
occurrence and continuance of a Default or reduction or termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.
Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately
available funds by 3:00 p.m. New York, New York time, in the same manner as provided in Section
2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis
mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly
pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative
Agent shall notify the Borrower of any participation in any Swingline Loan acquired pursuant to
this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the
Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender
from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after
receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be
promptly remitted to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made
their payments pursuant to this paragraph and to the Swingline Lender, as their interests may
appear; provided that any such payment so remitted shall be repaid to the Swingline Lender
or to the Administrative Agent, as applicable, if and to the extent such payment is required to be
refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan
pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.
Notwithstanding the foregoing, a Lender shall not have any obligation to acquire a participation in
a Swingline Loan pursuant to this paragraph if an Event of Default shall have occurred and be
continuing at the time such Swingline Loan was made and such Lender shall have notified the
Swingline Lender in writing, at least one (1) Business Day prior to the time such Swingline Loan
was made, that such Event of Default has occurred and that such Lender will not acquire
participations in Swingline Loans made while such Event of Default is continuing.

     Section 2.10 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:

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

37

 

          (a) fees pursuant to Section 3.05(a) shall cease to accrue on the unused portion of
the Commitment of such Defaulting Lender;

          (b) the Commitment and the principal amount of the Loans and participation interests in
Letters of Credit and Swingline Loans of such Defaulting Lender shall not be included in
determining whether all Lenders, the Required Lenders or the Majority 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 (i) that would increase the
Commitment or the Maximum Credit Amount of such Defaulting Lender or (ii) 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;

          (c) if any Swingline Exposure or LC Exposure exists at the time a Lender becomes a Defaulting
Lender then:

               (i) all or any part of such Swingline Exposure and LC Exposure shall be reallocated among the
non-Defaulting Lenders in accordance with their respective Commitments but only to the extent (A)
the sum of all non-Defaulting Lenders’ Credit Exposure plus such Defaulting Lender’s Swingline
Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments and
(B) the conditions set forth in Section 6.02 are satisfied at such time; and

               (ii) if the reallocation described in clause (i) above cannot, or can only partially, be
effected, the Borrower shall within two (2) Business Days following notice by the Administrative
Agent cash collateralize such Defaulting Lender’s LC Exposure and Swingline Exposure (after giving
effect to any partial reallocation pursuant to clause (i) above) for so long as such LC Exposure
and Swingline Exposure are outstanding and the relevant Defaulting Lender continues to be a
Defaulting Lender in accordance with the procedures set forth in Section 2.08(j);

               (iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure
pursuant to this Section 4.04(c), 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;

               (iv) if the applicable LC Exposure of the non-Defaulting Lenders is reallocated pursuant to
this Section 4.04(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’ reallocated Commitment and LC Exposure; or

               (v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated
pursuant to this Section 4.04(c), then, without prejudice to any rights or remedies of any
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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

38

 

3.05(a) and letter of credit fees
payable under Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be
payable to the applicable Issuing Bank until such LC Exposure is cash collateralized and/or
reallocated; and

          (d) so long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required
to fund any Swingline Loan and no Issuing Bank shall 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 4.04(c), and participating interests in
any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated
among non-Defaulting Lenders in a manner consistent with Section 4.04(c)(i) (and any
Defaulting Lender shall not participate therein).

     In the event that the Administrative Agent, the Borrower, the Swingline Lender, and each
Issuing Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused
such Defaulting Lender to be a Defaulting Lender, then the LC Exposure and Swingline Exposure of
the non-Defaulting Lenders shall be readjusted to reflect the inclusion of such Defaulting Lender’s
Commitment and on such date such Defaulting Lender shall purchase at par such of the Loans of the
other Lenders as the Administrative Agent shall determine may be necessary in order for such
Defaulting Lender to hold such Loans in accordance with its Commitment.

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 Borrowing plus the
Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (c) Swingline Loans. Swingline Loans shall bear interest at the Alternate Base Rate
plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

          (d) Post-Default Rate. Notwithstanding the foregoing, if any principal of or interest
on any Loan or any fee or other amount payable by the Loan Parties hereunder or under any other
Loan Document is not paid when due, whether at stated maturity, upon acceleration or otherwise,
such overdue amount shall bear interest, after as well as before judgment, at a rate per

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

39

 

annum equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section
3.02(a), but in no event to exceed the Highest Lawful Rate.

          (e) 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 (i)
interest accrued pursuant to Section 3.02(d) shall be payable on demand, (ii) 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 (iii) 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.

          (f) 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, 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 as an ABR
Borrowing.

     Section 3.04 Prepayments.

          (a) Optional Prepayments. The Borrower shall have the right at any time and from time
to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with
Section 3.04(b).

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

40

 

          (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the
Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder not later
than 2:00 p.m., New York, New York time, on the Business Day 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 Credit Exposures exceeds the total
Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such termination or
reduction in an aggregate principal amount equal to such excess, and (B) 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(i).

               (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in
accordance with Section 2.07 or Section 8.13(d), if the total Credit Exposures
exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall, within thirty (30)
days of such redetermination or adjustment of the Borrowing Base, elect: (A) (1) to prepay the
Loans in an aggregate principal amount equal to such excess and (2) if any excess remains after
prepaying all of the Borrowings as a result of an LC Exposure, to 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(i); (B) to pay such excess in four (4) equal installments, the first (1st)
such installment being due and payable by the first (1st) Business Day after such election has been
made by the Borrower and the three (3) remaining installments due monthly thereafter until such
excess is paid in full; (C) to grant first-priority Liens in favor of the Administrative Agent in
accordance with Section 8.14(a) on additional proved Oil and Gas Properties of the Loan
Parties not previously evaluated in determining the Borrowing Base that are satisfactory to the
Administrative Agent and are determined by the Administrative Agent to have a value equal to or
greater than the amount of such excess; or (D) to make partial payments under the preceding clauses
(A) or (B) and also to provide Collateral under the preceding clause (C) that together are
effective to deal with such excess. In the case of an election by the Borrower of the option set
forth in clause (A) above, the Borrower shall be obligated to pay such prepayment and/or deposit of
cash collateral amount within forty-five (45) days following its receipt of the New Borrowing Base
Notice in accordance with Section 2.07(d) or the date the adjustment occurs;
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; provided further that if a sale of Property containing
proved reserves constituting a portion of the Borrowing Base occurs pursuant to Section
9.12 during such period when the total Credit Exposures exceeds the redetermined or adjusted
Borrowing Base, then the

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

41

 

proceeds of such sale of Property, to the extent thereof and after
deducting taxes and costs of sale, shall be used first to prepay the Borrowings in an aggregate
principal amount equal to such excess.

               (iii) Upon any adjustments to the Borrowing Base pursuant to Section 9.02(f),
Section 9.12 or Section 9.19, if the total Credit Exposures exceeds the Borrowing
Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal
amount equal to such excess, and (B) 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(i). The
Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on or before
the first (1st) Business Day after it receives cash proceeds as a result of such Debt incurrence,
disposition or Unwind; 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) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied,
first, to any Swingline Loans then outstanding, second, ratably to any ABR
Borrowings then outstanding, and, third, 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.

               (v) 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

Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to
each Issuing Bank, for its own account, a fronting fee, which shall accrue at the rate of 0.200%
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

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 2:00 p.m., New York, New York time, on the date when due, in dollars that

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

43

 

constitute immediately available funds, without defense, deduction, recoupment, set-off or
counterclaim. Fees, once paid, shall not be refundable under any circumstances absent manifest
error (e.g., as a result of a clerical mistake). 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, except payments
to be made directly to an Issuing Bank or the Swingline Lender as expressly provided herein and
except that payments pursuant to Section 5.01, 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
(i) 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
(ii) 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 or Swingline Loans resulting in such Lender
receiving payment of a greater proportion of the aggregate amount of its Loans and participations
in LC Disbursements or Swingline Loans 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 and Swingline Loans; provided that
(i) 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 (ii) 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 or Swingline Loans to any assignee or participant, other than to the Borrower or any
Subsidiary or Affiliate thereof (as to which the provisions of this Section
4.01(c) shall apply). 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 rights of set-off and counterclaim

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

44

 

with respect to such participation as fully as if such Lender were a direct creditor of the
Borrower 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 any 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 such Issuing Bank, as the case may be, the amount due. In such event, if the Borrower
has not in fact made such payment, then each of the Lenders or such 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 such 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 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 2.09(c) or Section 4.02 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.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment
by the Loan Parties 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 Loan
Parties’ interest in and to production and all proceeds attributable thereto that 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 Indebtedness and other obligations
described therein and secured thereby. Notwithstanding the assignment contained in such Security
Instruments, unless an Event of Default has occurred and is continuing (a) 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 Borrower and its
Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such
actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such
Restricted Subsidiaries.

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:

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

45

 

               (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;

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 Loan Parties 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 any 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 such Issuing Bank’s capital or on the capital of such Lender’s or such 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 such
Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such
Issuing Bank’s holding company could have achieved but for such Change in Law (taking into
consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or
such Issuing Bank’s holding company with respect to capital adequacy), then from time to time the
Loan Parties will pay to such Lender or such Issuing Bank, as the case may be, such additional
amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such
Issuing Bank’s holding company for any such reduction suffered.

          (c) Certificates. A certificate of a Lender or any Issuing Bank setting forth the
amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company,
as the case may be, as specified in Section 5.01(a) or (b) and reasonably detailed
calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest
error. The Loan Parties shall pay such Lender or such 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 any Issuing Bank to demand compensation pursuant to this Section 5.01
shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such
compensation; provided that the Loan Parties shall not be required to compensate a Lender
or an Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions
incurred more than one hundred eighty (180) days prior to the date that such Lender or such 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 such 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 one hundred eighty (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 (a) 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), (b) the conversion of any Eurodollar Loan into an
ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to
borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice
delivered pursuant hereto, or (d) the assignment 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 Loan Parties shall compensate each Lender
upon request 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 the excess, if any, of (i) the amount of interest which would have accrued on the
prepaid or otherwise affected 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 (ii) 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 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Loan
Parties 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 Loan Parties under any Loan Document shall be made free and clear of and without deduction for
any Indemnified Taxes or Other Taxes; provided that if a Loan Party shall be required to
deduct any Indemnified Taxes or Other Taxes from such payments, then (i) 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 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, (ii) the Loan Parties shall make such deductions and (iii) the Loan
Parties 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 Loan Parties shall pay any Other Taxes
to the relevant Governmental Authority in accordance with applicable law.

          (c) Indemnification by the Borrower. The Loan Parties shall indemnify each Agent, each
Lender and each Issuing Bank, within ten (10) days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by such Agent, such Lender or such Issuing
Bank, as the case may be, on or with respect to any payment by or on account of any obligation of a
Loan Party 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, whether or not such

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

47

 

Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate of such Agent, a Lender or an Issuing Bank as to the amount
of such payment or liability under this Section 5.03 shall be delivered to the Borrower and
shall be conclusive absent manifest error.

          (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by a Loan Party 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 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) Tax Refunds. If an Agent or a Lender determines, in its reasonable discretion,
that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by
the Loan Parties or with respect to which the Loan Parties have paid additional amounts pursuant to
this Section 5.03, it shall pay over such refund to such Loan Party (but only to the extent
of indemnity payments made, or additional amounts paid, by such Loan Party under this Section
5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of all
out-of-pocket expenses of such Agent or such Lender and without interest (other than any interest
paid by the relevant Governmental Authority with respect to such refund); provided, that
the Loan Parties, upon the request of such Agent or such Lender, agree to repay the amount paid
over to the Loan Party (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to such Agent or such Lender in the event such Agent or such Lender is
required to repay such refund to such Governmental Authority. This Section 5.03 shall not
be construed to require any Agent or any Lender to make available its tax returns (or any other
information relating to its taxes which it deems confidential) to any Loan Party or any other
Person.

     Section 5.04 Mitigation Obligations.

          (a) Designation of Different Lending Office. If any Lender requests compensation under
Section 5.01, or if a Loan Party 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
(i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section
5.03, as the case may be, in the future and (ii) would not subject such Lender to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

48

 

Loan Parties hereby agree 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 or gives notice of “Affected Loans” under Section 5.05, (ii) the Loan
Parties are 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 hereunder, or (iv) any Lender has not approved (or is not deemed to have approved) an
increase in the Borrowing Base proposed by the Administrative Agent pursuant to Section
2.07(c)(iii), then the Borrower may, at its sole expense and effort, upon notice to such Lender
and the Administrative Agent, (A) 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
obligations (which assignee may be another Lender, if a Lender accepts such assignment) or (B)
require such Lender to be removed as a Lender under this Agreement and the other Loan Documents
with a corresponding reduction in the Aggregate Maximum Credit Amount equal to the Maximum Credit
Amount of such Lender; provided that (1) if a Lender is removed as a Lender hereunder, the
Loan Parties have paid such Lender all amounts due and owing under this Agreement and the other
Loan Documents, including, without limitation, all principal, accrued interest, fees and breakage
costs, (2) in the case of a required assignment of interest, the Borrower shall have received the
prior written consent of the Administrative Agent, which consent shall not unreasonably be
withheld, (3) 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 a Loan Party (in the case of all other
amounts) and (4) 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 (a) 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 (b) 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.

Loan Party’s corporate, partnership or LLC powers and have been duly authorized by all necessary
action (including, without limitation, any action required to be taken by any class of directors

any consent or approval of, registration or filing with, or any other action by, any Governmental
Authority or any other third Person (including

or any other Person), nor is any such consent, approval, registration, filing or other action

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, (ii) those third party approvals or consents which, if not made or obtained, would not

by any Loan Party, (d) will not violate or result in a default under any other agreement or
instrument binding upon any Loan Party or its Properties, or give rise to a right thereunder to
require any payment to be made by any Loan Party, in any way that could reasonably be expected to
have a Material Adverse Effect, and (e) will not result in the creation or imposition of any Lien
on any Property of any Loan Party (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 (i) audited consolidated
financial statements of the Borrower and its Consolidated Subsidiaries for the fiscal year ended
December 31, 2008, and (ii) unaudited combined financial statements of the Borrower and its
Consolidated Subsidiaries for the fiscal quarter ending September 30, 2009, all in form and
substance reasonably satisfactory to the Administrative Agent. Such financial statements described
in clauses (i) and (ii) above present fairly, in all material respects, the financial position and
results of operations and cash flows of such Persons as of such dates and for such periods in
accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the
case of the unaudited quarterly financial statements.

          (b) Since the date of the last delivery of financial statements pursuant to
Section 7.04(a) or Section 8.01, (i) there has been no event, development or
circumstance that has had or could reasonably be expected to have a Material Adverse Effect and
(ii) the business of each Loan Party and each Restricted Subsidiary has been conducted in the
ordinary course consistent with past business practices.

          (c) Except as set forth on Schedule 7.21, on the most recent financial
statement delivered pursuant to Section 7.04(a) or Section 8.01(a) or (b),

investigations or proceedings by or before any arbitrator or Governmental Authority pending against
or, to the knowledge of any Loan Party, threatened in writing against or affecting any Loan Party
or any Subsidiary (i) as to which there is a reasonable possibility of an adverse determination

          (b) Since the date of this Agreement, there has been no change in the status of the
matters disclosed in Schedule 7.05 that, individually or in the aggregate, has resulted in a
Material Adverse Effect or has resulted in 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.

     Section 7.06 Environmental Matters. Except as could not reasonably be
expected to have a Material Adverse Effect (or with respect to (c), (d) and (e) below, where the
failure to take such actions could not be reasonably expected to have a Material Adverse Effect):

          (a) neither any Property of a Loan Party or any Subsidiary nor the operations
conducted thereon violate any order or requirement of any court or Governmental Authority or any
Environmental Laws.

          (b) no Property of a Loan Party or any Subsidiary nor the operations currently
conducted thereon or, to the knowledge of any Loan Party, 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.

          (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 each Loan Party and each Subsidiary, 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 each Loan Party and each Subsidiary are
in compliance with the terms and conditions of all such notices, permits, licenses and similar
authorizations.

          (d) to the knowledge of each Loan Party, all hazardous substances, solid waste and
oil and gas waste, if any, generated at any and all Property of each Loan Party or any Subsidiary
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 in transporting, treating or disposing of the same all such transport carriers
and treatment and disposal facilities have been and are operating in compliance with Environmental
Laws 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 Loan Party has taken all steps reasonably necessary 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,

          (f) to the extent applicable, all Property of each Loan Party and each Subsidiary
currently satisfies all design, operation, and equipment requirements imposed by the OPA, and each
Loan Party does not have 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) no Loan Party nor any Subsidiary 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 Loan Party and each Restricted Subsidiary 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) No Loan Party is in default nor has any event or circumstance occurred which,
but for the expiration of any applicable grace period or the giving of notice, or both, would
constitute a default or would require
any Loan Party 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 Loan
Party or any of their Properties is bound.

          (c) No Default has occurred and is continuing.

     Section 7.08 Investment Company Act. No Loan Party nor any Subsidiary 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 [Reserved].

     Section 7.10 Taxes. Each Loan Party and each Subsidiary 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 (a) Taxes that are being contested in
good faith by appropriate proceedings and for which each Loan Party or such Subsidiary, as
applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) 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 each Loan Party and each Subsidiary in
respect of Taxes and other governmental charges are, in the reasonable opinion of such Loan Party,
adequate. No Tax Lien has been filed and, to the knowledge of each Loan Party, no claim is being
asserted with respect to any such Tax or other such governmental charge.

     Section 7.11 ERISA.

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

56

 

          (a) Each Loan Party, each Subsidiary 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) Except as could not reasonably be expected to result in liability in excess of
$500,000, no act, omission or transaction has occurred which could result in imposition on each
Loan Party, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) 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 (ii) breach of fiduciary duty liability
damages under section 409 of ERISA.

          (d) No Plan (other than a defined contribution plan) or trust created under any such
Plan has been terminated since September 2, 1974. No liability to the PBGC (other than for the
payment of current premiums which are not past due) by any Loan Party, any Subsidiary or any ERISA

incurred with respect to any Plan. No ERISA Event with respect to any Plan has occurred.

          (e) Full payment when due has been made of all amounts which each Loan Party, each
Subsidiary or each 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 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 does not,
as of the end of each Loan Party’s most recently ended fiscal 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) No Loan Party, no Subsidiary and no 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 a Loan Party, a Subsidiary or an ERISA Affiliate in its
sole discretion at any time without any material liability to any Loan Party.

          (h) No Loan Party, no Subsidiary and no 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.

     Section 7.12 Disclosure; No Material Misstatements. Each Loan Party has
disclosed to the Administrative Agent and the Lenders all agreements, instruments and corporate or
other restrictions to which it or any Restricted Subsidiary is subject, and all other matters
peculiar to it and known to it, that, individually or in the aggregate, could reasonably be
expected to result in a Material Adverse Effect. Taken as a whole, none of the other reports,
financial statements, certificates or other information furnished by or on behalf of any Loan Party
to the Administrative Agent or any Lender or any of their Affiliates in connection with the
negotiation of this Agreement or any other Loan Document or delivered hereunder or under any other
Loan Document (as modified or supplemented by other information so furnished) contain material
misstatements of fact or omit to state material facts necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading; provided that,
with respect to projected financial information, prospect information, geological and geophysical
data and engineering projections, each Loan Party represents only that such information was
prepared in good faith based upon assumptions believed to be reasonable at the time. To the
knowledge of each Loan Party, there is no fact peculiar to such party or any Subsidiary which could
reasonably be expected to have a Material Adverse Effect or in the future is reasonably likely to
have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan
Documents or the other documents, certificates and statements furnished to the Administrative Agent
or the Lenders by or on behalf of each Loan Party or any Subsidiary in connection with the
transactions contemplated hereby. There are no statements or conclusions known to any Loan Party in
any 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 and production and cost
estimates contained in each Reserve Report are necessarily based upon professional opinions,
estimates and projections and that each Loan Party and each Subsidiary do not warrant that such
opinions, estimates and projections will ultimately prove to have been accurate.

     Section 7.13 Insurance. Each Loan Party has (a) all insurance policies
sufficient for the compliance by each of them with all material Governmental Requirements and all
material agreements and (b) 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
each Loan Party. The Administrative Agent and the Lenders have been named as additional insureds in
respect of such liability insurance policies and the Administrative Agent has been named as loss
payee with respect to Property loss insurance.

     Section 7.14 Restriction on Liens. No Loan Party is a party to any material
agreement or arrangement (other than leases creating Liens permitted by Section 9.03(b) or
(c), but then only on the Property subject of such lease), or subject to any order, judgment,
writ or decree, which either restricts or purports to restrict its ability to grant Liens to the
Administrative Agent and the Lenders on or in respect of their Properties to secure the
Indebtedness and the Loan Documents.

     Section 7.15 Subsidiaries. Except as set forth on Schedule 7.15 or as
disclosed in writing to the Administrative Agent (which shall promptly furnish a copy to the
Lenders), which shall be a supplement to Schedule 7.15, (a) each Loan Party has no
Subsidiaries, (b) each

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

58

 

Subsidiary is a Wholly-Owned Subsidiary and (c) no Loan Party nor any Subsidiary of the Borrower has any Foreign Subsidiaries. Schedule
7.15 indentifies each Subsidiary as either a Restricted Subsidiary or an Unrestricted
Subsidiary.

     Section 7.16 Location of Business and Offices. The jurisdiction of
organization, the name as listed in the public records of the state of organization and the
organizational identification number of each Loan Party is set forth on Schedule 7.16 (or, in
each case, as set forth in a notice delivered to the Administrative Agent pursuant to Section
8.01(m) in accordance with Section 12.01). Each Loan Party’s principal place of
business is located at the address specified in Section 12.01 (or as set forth in a notice
delivered pursuant to Section 8.01(m) and Section 12.01(c)).

     Section 7.17 Properties; Titles, Etc.

          (a) Except as disclosed in Schedule 7.17, the Loan Parties have good and
defensible title in all material respects to the proved Oil and Gas Properties evaluated in the
most recently delivered Reserve Report (excluding, to the extent this representation and warranty
is deemed to be made after the Effective Date, any such Oil and Gas Properties sold or transferred
in compliance with Section 9.12) and good title in all material respects to all their
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, each Loan Party 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 any Loan Party 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 Loan Party’s net revenue interest in such
Property.

          (b) All material leases and agreements necessary for the conduct of the business of
each Loan Party 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 time or both would give
rise to a default under any such lease or leases, which could reasonably be expected to result in a
Material Adverse Effect.

          (c) The rights and Properties presently owned, leased or licensed by each Loan Party
including, without limitation, all easements and rights of way, include all rights and Properties
necessary to permit each Loan Party to conduct its business in all material respects in the same
manner as such business has been conducted prior to the date hereof.

          (d) All of the material Properties of each Loan Party which are reasonably necessary
for the operation of their businesses are in good working condition and are maintained in
accordance with prudent business standards.

          (e) Each Loan Party owns, or is licensed to use, all trademarks, tradenames,
copyrights, patents and other intellectual Property material to its business, and the use thereof
by each Loan Party 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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

59

 

a Material Adverse Effect. Each Loan Party either owns or has 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 7.18 Maintenance of Properties. Except for such acts or failures to
act as could not be reasonably expected to have a Material Adverse Effect, (a) the proved Oil and
Gas Properties of the Loan Properties (and Properties unitized therewith) have been maintained,
operated and developed in a good and workmanlike manner and in conformity with all Government
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 of the Loan Parties, and (b) the other Oil and
Gas Properties of the Loan Parties (and Properties unitized therewith) have been held by the Loan
Parties in conformity with all Government Requirements and in conformity with the provisions of all
leases, subleases and other contracts and agreements forming a part of the Oil and Gas Properties
of the Loan Parties. Specifically in connection with the foregoing, except for those as could not
be reasonably expected to have a Material Adverse Effect, (i) no proved Oil and Gas Property of the
Loan Parties 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 (ii) to the knowledge of each Loan Party, none of the wells
comprising a part of the proved Oil and Gas Properties (or Properties unitized therewith) of the
Loan Parties is deviated from the vertical more than the maximum permitted by Government
Requirements, and such wells are, in fact, bottomed under and are producing from, and the well
bores are wholly within, the proved Oil and Gas Properties (or in the case of wells located on
Properties unitized therewith, such unitized Properties) of the Loan Parties. All pipelines, wells,
gas processing plants, platforms and other material improvements, fixtures and equipment owned in
whole or in part by each Loan Party 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 that are operated by each Loan Party, in a manner consistent with each Loan Party’s past
practices (other than those the failure of which to maintain in accordance with this Section
7.18 could not reasonably be expect to have a Material Adverse Effect).

     Section 7.19 Gas Imbalances, Prepayments. Except as set forth on
Schedule 7.19 or as set forth 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 any Loan Party to deliver Hydrocarbons produced from the proved Oil and Gas
Properties at some future time without then or thereafter receiving full payment therefor exceeding
500 mmcf equivalent in the aggregate for all Loan Parties.

     Section 7.20 Marketing of Production. Except for contracts listed and in
effect on the date hereof on Schedule 7.20 or 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

60

 

each Loan Party represents that it is receiving a price for all production sold
thereunder which is computed substantially in accordance with the terms of the relevant contract
and is not having deliveries curtailed substantially below the subject Property’s delivery
capacity), 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 its Hydrocarbons (including, without
limitation, calls on or other rights to purchase, production, whether or not the same are currently
being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a
maturity or expiry date of longer than six (6) months.

     Section 7.21 Hedging Agreements. Schedule 7.21 sets forth, as of the
date hereof, a true and complete list of all Hedging Agreements of the Loan Parties, the material
terms thereof (including the type, term, effective date, termination date and notional amounts or
volumes), all credit support agreements relating thereto other than the Loan Documents (including
any margin required or supplied) and the counterparty to each such agreement. After the date
hereof, each report that has been delivered by the Borrower pursuant to Section 8.01(e)
sets forth the same information, as well as any additional information required by Section
8.01(e), as of the date(s) specified therein.

     Section 7.22 Use of Loans and Letters of Credit. The proceeds of the Loans
and the Letters of Credit shall be used to refinance the loans outstanding under the Existing
Credit Agreement, to pay fees, commissions and expenses in connection with the transactions
contemplated hereby, and to finance ongoing working capital and for other general corporate
purposes of the Borrower and its Restricted Subsidiaries, including the acquisition of exploration
and production and midstream properties and to benefit the Unrestricted Subsidiaries as allowed by
Section 9.05. The Loan Parties and the 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 7.23 Solvency. Before and after giving effect to the transactions
contemplated hereby, (a) the aggregate assets, at a fair valuation, of the Loan Parties, taken as a
whole, will exceed the aggregate Debt of the
Loan Parties on a consolidated basis, as the Debt becomes absolute and matures, (b) each of
the Loan Parties will not have incurred or intended to incur, and will not believe that it will
incur, Debt beyond its ability to pay such Debt as such Debt becomes absolute and matures and (c)
each of the Loan Parties will not have (and will have no reason to believe that it will have
thereafter) unreasonably small capital for the conduct of its business.

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 7.19 with respect to its proved Oil and Gas
Properties evaluated in such Reserve Report which would require any Loan Party 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, (v) none of their proved Oil and Gas

     Section 8.13 Title Information.

          (a) On or before the 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 acceptable to
the Administrative Agent covering enough of the proved 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,
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

Properties, either (i) cure any such title defects or exceptions (including defects or exceptions
as to priority) which are not permitted by Section 9.03, (ii) substitute Mortgaged
Properties acceptable to the Administrative Agent with no title defects or exceptions except for
Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition)
having an equivalent value or (iii) deliver title information in form and substance acceptable to
the Administrative Agent so that it shall have received, together with title information previously

value of the proved Oil and Gas Properties evaluated by such Reserve Report.

          (c) [Reserved.]

the 60-day period or the Borrower does not comply with the requirements to provide acceptable title
information covering eighty percent (80%) of the total 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

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

69

 

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 the remedy by any Agent or the Lenders. To
the extent that the Administrative Agent or the Required Lenders are not reasonably 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 Required Lenders to cause the Borrower to be in
compliance with the requirement to provide acceptable title information on eighty percent (80%) of
the total value of the proved Oil and Gas Properties of the Loan Parties. This new Borrowing Base
shall become effective immediately after receipt of such notice.

     Section 8.14 Additional Collateral; Additional Guarantors.

          (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 proved Oil and Gas Properties that constitute
Mortgaged Properties represent (i) one hundred percent (100%) of the proved Oil and Gas Properties
held by the Loan Parties in San Juan County, Utah and (ii) in the aggregate, at least eighty
percent (80%) of the total value of the proved 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 proved Oil and Gas Properties that
constitute Mortgaged Properties do not represent (i) one hundred percent (100%) of the proved Oil
and Gas Properties held by the Loan Parties in San Juan County, Utah and (ii) in the aggregate, at
least eighty percent (80%) of the total value of the proved Oil and Gas Properties evaluated in the
most recently completed Reserve Report, then each Loan Party shall grant to the Administrative
Agent as security for the Indebtedness a first-priority Lien interest (subject only to Excepted
Liens of the type described in clauses (a) to (d) and (f) of the definition thereof, but subject to
the provisos at the end of such definition) on additional proved Oil and Gas Properties not already
subject to a Lien of the Security Instruments such that after giving effect thereto, the proved Oil
and Gas Properties that constitute Mortgaged Properties will represent (i) one hundred percent
(100%) of the proved Oil and Gas Properties held by the Loan Parties in San Juan County, Utah and
(ii) otherwise, at least eighty percent (80%) of such total value. All such Liens will be created
and perfected by and in accordance with the provisions of mortgages, deeds of trust, security
agreements and financing statements or other Security Instruments, all in form and substance
satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where
necessary or appropriate) counterparts for recording purposes.

          (b) The Borrower shall promptly cause each Domestic Subsidiary (other than any
Subsidiary classified as such based on any Loan Party or any other Subsidiary being a general
partner thereof, unless such Subsidiary is a Wholly-Owned Subsidiary) now existing or hereafter
created or acquired that is not an Unrestricted Subsidiary to guarantee the Indebtedness pursuant
to the Guaranty and Collateral Agreement. In connection with any such guaranty, the Borrower shall,
or shall cause each such Domestic Subsidiary to, (A) assume the obligations under the Guaranty and
Collateral Agreement and this Agreement applicable to a Guarantor, by

Resolute Energy Corporation

executing and delivering a
supplement or joinder to the Guaranty and Collateral Agreement, in form and substance satisfactory
to the Administrative Agent, (B) pledge all of the Equity Interests that it owns in any Loan Party
(including, without limitation, delivery of any original stock certificates or other certificates
evidencing the Equity Interests of such Loan Party, together with an appropriate undated stock
powers for each certificate duly executed in blank by the registered owner thereof) and (C) execute
and deliver such other additional closing documents, certificates and legal opinions as shall
reasonably be requested by the Administrative Agent.

          (c) The Loan Parties will at all times cause the other material Property of the Loan
Parties of the types not addressed by clauses (a) and (b) above to be subject to a perfected first
priority Lien (subject only to Liens permitted by Section 9.03) pursuant to the Security
Instruments to the extent that such Lien can be granted and perfected under applicable law and
subject to any exceptions set forth in the Security Instruments; provided, that the
Administrative Agent may waive the requirements of this Section 8.14(c), in its sole discretion,
with respect to (i) certain Property if the Administrative Agent determines that the cost of
obtaining a Lien on such Property is excessive in relation to the value afforded thereby, (ii)
Property with respect to which a Lien cannot be perfected under the Uniform Commercial Code and
(iii) deposit account control agreements and security account control agreements.

     Section 8.15 ERISA Compliance. Except as could not reasonably be expected
to result in liability of any Loan Party and any Subsidiary of more than $1,000,000 individually or
in the aggregate for all Loan Parties and the Subsidiaries, the Borrower will promptly furnish and
will cause the Subsidiaries and any ERISA Affiliate to promptly furnish to the Administrative Agent
(i) promptly after the filing thereof with the United States Secretary of Labor, the Internal
Revenue Service or the PBGC, copies of each annual and other report with respect to each Plan or
any trust created thereunder, (ii) promptly upon becoming aware of the occurrence of any ERISA
Event or of any “prohibited transaction,” as described in section 406 of ERISA or in section 4975
of the Code, in connection with any Plan or any trust created thereunder, a written notice signed
by the President or the principal Financial Officer, the Subsidiary or the ERISA Affiliate, as the
case may be, specifying the nature thereof, what action such Loan Party, 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 (iii) promptly upon receipt thereof, copies of any notice of the PBGC’s intention to
terminate or to have a trustee appointed to administer any Plan. With respect to each Plan (other
than a Multiemployer Plan) except as could not reasonably be expected to result in liability to any
Loan Party and any Subsidiary of less than $1,000,000 individually or in the aggregate for all Loan
Parties and all Subsidiaries, such Loan Party will, and will cause each Subsidiary and ERISA
Affiliate to, (i) satisfy in full and in a timely manner, without incurring any late payment or
underpayment charge or penalty and without giving rise to any lien, all of the contribution and

Administrative Agent, the Borrower or such Loan Party shall deliver a certificate of a Responsible
Officer of such Loan Party certifying to that effect),

               (iii) if such Transfer of any Borrowing Base Property or Restricted Subsidiary owning
Borrowing Base Properties included in the most recently delivered Reserve Report during any period
between two successive Scheduled Redetermination Dates has a fair market value (together with all
other Transfers of Borrowing Base Properties or Restricted Subsidiaries owning Borrowing Base
Properties included in the most recently delivered Reserve Report during such period) in excess of
ten percent (10%) of the Borrowing Base then in effect as determined by the Required Lenders, the
Borrowing Base shall be reduced, effective immediately upon such Transfer, by an amount equal to
the value, if any, assigned such Borrowing Base Property (or Borrowing Base Properties) in the most
recently delivered Reserve Report and any mandatory prepayments required by Section
3.04(c)(iii) shall be made concurrently and

               (iv) if any such Transfer is of a Restricted Subsidiary owning Borrowing Base Properties, such

similar rights;

provided that the cash proceeds (net of costs of sale) of any Transfer of any Borrowing
Base Property (A) when any Event of Default exists shall be used to prepay the Borrowings and (B)

remedial obligations could reasonably be expected to have a Material Adverse Effect.

     Section 9.14 Transactions with Affiliates. Each Loan Party will not enter into any
transaction, including, without limitation, any purchase, sale, lease or exchange of Property or

less favorable to it than it would obtain in a comparable arm’s length transaction with a Person
not an Affiliate.

     Section 9.15 Subsidiaries. Each Loan Party shall not create or acquire any additional
Subsidiaries, except that the Borrower and any of its Restricted Subsidiaries may create or acquire
any additional Subsidiaries if the Borrower or such Restricted Subsidiary gives prior written
notice to the Administrative Agent of such creation or acquisition and, if such additional
Subsidiary is a Restricted Subsidiary, complies with Section 8.14(b). The Borrower shall

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 Restricted
Subsidiary from paying dividends or making distributions to any Loan Party, or which requires the

and Gas Properties of a Loan Party or any Restricted Subsidiary.

     Section 9.19 Hedging Agreements. Each Loan Party will not enter into any Hedging
Agreements with any Person other than:

          (a) Hedging Agreements in respect of commodities (i) with an Approved Counterparty and (ii)
which, when aggregated with all other commodity Hedging Agreements of the Loan Parties then in
effect (but excluding all basis differential swaps on volumes already hedged pursuant to other
Hedging Agreements), do not have the net effect of constituting a call (whether under physical or
derivative Hedging Agreements) on more than eighty-five (85%) of the reasonably anticipated
projected production from proved, developed, producing Oil and Gas Properties of the Loan Parties
for each year during the period during which such Hedging Agreements are in effect for each of
crude oil and natural gas, calculated separately, and

          (b) Hedging Agreements in respect of interest rates with an Approved Counterparty, as follows:
(i) Hedging Agreements effectively converting interest rates from fixed to floating, the notional
amounts of which (when aggregated and netted with all other Hedging Agreements of the Borrower and
its Restricted Subsidiaries then in effect) do not exceed the then outstanding principal amount of
the Borrower’s Debt for borrowed money which bears interest at a fixed rate and (ii) Hedging
Agreements effectively converting interest rates from floating to fixed, the notional amounts of
which (when aggregated and netted with all other Hedging Agreements of the Borrower and its
Restricted Subsidiaries then in effect) do not exceed (A) for revolving loans, seventy-five (75%)
of the then outstanding principal amount of the Borrower’s Debt for revolving loans which bear
interest at a floating rate and (B) for term loans, one hundred percent (100%) of the then
outstanding principal amount of the Borrower’s Debt for term loans which bear interest at a
floating rate.

In no event shall any Hedging Agreement to which the Borrower or any of its Restricted Subsidiaries
is a party contain any requirement, agreement or covenant for the Borrower or any Restricted
Subsidiary to post cash or other collateral or margin (except for Letters of Credit not exceeding
$2,500,000 in the aggregate at any time and collateral subject to Liens allowed under Section
9.03(d)), other than pursuant to the Security Instruments for the benefit of the Secured
Hedging Providers, to secure their obligations under such Hedging Agreement or to cover market
exposures. The Loan Parties will not unwind, sell, terminate, restructure, modify or otherwise
affect (“Unwind”) any Hedging Agreement in respect of commodities that was in effect at the
time of the most recent Borrowing Base determination (the “Borrowing Base Hedging
Contracts”) where the net marked to market economic effect of such Hedging Agreement
Restructuring on the date thereof is negative (which, if such Hedging Agreement Restructuring is
settled for cash only, shall equal the net amount of cash such Loan Parties receive), unless (a)
the net marked to market economic effect of such Hedging Agreement Restructuring on the date
thereof, when combined with the net marked to market economic effect of all other Hedging

Agreement Restructurings consummated during the period since the last Redetermination Date, is less
than or equal to five percent (5%) of the value of the Borrowing Base then in effect, or (b) if the
net marked to market economic effect of such Hedging Agreement Restructuring on the date thereof,
when combined with the net marked to market economic effect of all other Hedging Agreement
Restructurings consummated during the period since the last Redetermination Date, is greater than
five percent (5%) of the Borrowing Base then in effect, the Borrowing Base is reduced in accordance
with the following sentence. The Administrative Agent shall recommend, if it determines in its
judgment that it is appropriate to do so, a reduction of the Borrowing Base by the portion of the
Borrowing Base attributable to such net economic effect of the Hedging Agreement Restructuring
(based on the economic assumptions consistent with the Administrative Agent’s lending requirements
at that time). Such recommendation by the Administrative Agent shall not become effective until it
is approved by the Required Lenders pursuant to the mechanisms for decreases in the Borrowing Base
set forth in Section 2.07(c)(iii).

     Section 9.20 Designation and Conversion of Restricted and Unrestricted Subsidiaries.

          (a) Unless designated as an Unrestricted Subsidiary on Schedule 7.15 as of the date
hereof or thereafter, assuming compliance with Section 9.20(b), any Person that becomes a
Subsidiary of a Loan Party shall be classified as a Restricted Subsidiary.

          (b) The Borrower may designate by written notification thereof to the Administrative Agent,
any Restricted Subsidiary, including a newly formed or newly acquired Subsidiary, as an
Unrestricted Subsidiary if (i) neither such Subsidiary nor any of its Subsidiaries owns any Equity
Interests or Debt of, or owns or holds any Lien on any Property of, a Loan Party or any other
Subsidiary of a Loan Party that is not a Subsidiary of the Subsidiary to be so designated, (ii)
prior, and after giving effect, to such designation, (A) no Default or Event of Default shall have
occurred and be continuing and (B) the total Credit Exposures shall not exceed the Borrowing Base,
(iii) such designation is deemed to be an Investment in an Unrestricted Subsidiary in an amount
equal to the fair market value as of the date of such designation of the Borrower’s direct and
indirect ownership interest in such Subsidiary and such Investment would be permitted to be made at
the time of such designation under Section 9.05(h). Except as provided in this Section
9.20(b), no Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

          (c) The Borrower may designate any Unrestricted Subsidiary to be a Restricted Subsidiary if
after giving effect to such designation, (i) the representations and warranties of the Loan Parties

ARTICLE XI

THE AGENTS

     Section 11.01 Appointment; Powers. Each of the Lenders and each Issuing Bank hereby
irrevocably (subject to Section 11.06) 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 not have any duties or obligations except those expressly set forth in the Loan
Documents. Without limiting the generality of the foregoing, the Administrative Agent (a) shall not
be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred
and is continuing, (b) shall not have any duty to take any discretionary action or exercise any
discretionary powers, except as provided in Section 11.03, and (c) except as expressly set
forth herein, shall not have any duty to disclose, and shall not be liable for the failure to
disclose, any information relating to the Loan Parties or any Subsidiary that is communicated to or
obtained by the bank serving as an 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 it by a Loan Party or a Lender, and shall not be responsible for or have
any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in
connection with this Agreement or any other Loan Document, (ii) the contents of any certificate,
report or other document delivered hereunder or under any other Loan Document or in connection
herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or
other terms or conditions set forth herein or in any other Loan Document, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any
other agreement, instrument or document, (v) 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 it or as to those conditions precedent specifically required to be to its
satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the
financial or other condition of the Loan Parties and the Subsidiaries or any other obligor or
guarantor, or (vii) any failure by any Loan Party 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.

     Section 11.03 Action by Administrative Agent. The Administrative Agent shall not have
any duty to take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby that it is required to exercise in
writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as
shall be necessary under the circumstances as provided in Section 12.02) and in all cases
it shall be fully justified in failing or refusing to act hereunder or under any other Loan
Documents unless it shall (a) receive written instructions from the Majority Lenders or the
Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary
under the

Resolute Energy Corporation

85

 

circumstances as provided in Section 12.02) specifying the action to be taken and (b)
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 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 Arrangers,
the Syndication Agent nor any Co-Documentation Agent shall have any obligation to perform any act
in respect thereof. No Agent shall be liable for any action taken or not taken by it with the
consent or at the request of 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
12.02), and otherwise no Agent shall 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 and each of the Loan Parties, the Lenders and
each Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such
statement, except in the case of gross negligence or willful misconduct by such Agent. The
Administrative Agent may consult with legal counsel (who may be counsel for the Loan Parties),
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 Agents 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 it. 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 each 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 Agents. Subject to the appointment and
acceptance of a successor Agent as provided in this Section 11.06, any Agent may resign at
any time by notifying the Lenders, each Issuing Bank and the Borrower, and any 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, in consultation with and upon the approval of the
Borrower (so long as no Event of Default has occurred and is continuing), which approval shall not
be unreasonably withheld, 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 New
York, New York or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent
hereunder by a successor, such successor shall succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. The fees payable by the Borrower to a successor Agent
shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower
and such successor. After the Agent’s resignation hereunder, the provisions of this ARTICLE
XI and Section 12.03 shall continue in effect for the benefit of such retiring 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 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 Loan Parties or any Subsidiary
or other 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 Loan Parties or any Subsidiary 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 Loan Parties or any Subsidiary. Except for notices, reports
and other documents and information expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, neither the Agents nor the Arrangers 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 Loan Parties (or any of their Affiliates) which may come
into the possession of such Agent or any of its Affiliates. Each Lender hereby acknowledges and, by
becoming a party hereto, consents to the fact that Vinson & Elkins L.L.P. is acting as special
counsel to the Administrative Agent in connection with this

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

87

 

transaction. Each other party hereto will consult with its own legal counsel to the extent it
deems necessary in connection with the Loan Documents and the matters contemplated therein.

     Section 11.09 Authority to Release Guarantors, Collateral and Liens. Each Lender and
each Issuing Bank hereby authorizes the Administrative Agent to release any Collateral that the
Administrative Agent is permitted or required to release pursuant to Section 9.12 or that
is otherwise permitted to be sold or released pursuant to the terms of the Loan Documents and to
release from the Guaranty and Collateral Agreements any Guarantor that is permitted to be sold or
disposed of, or converted into an Unrestricted Subsidiary, pursuant to the terms of the Loan
Documents. Each Lender and each Issuing Bank hereby authorizes the Administrative Agent to execute
and deliver to a Loan Party, at such Loan Party’s sole cost and expense, any and all releases of
Guaranty and Collateral Agreements, Liens, termination statements, assignments or other documents
reasonably requested by such Loan Party in connection with any sale or other disposition of
Property to the extent such sale or other disposition or the release of such Collateral is
permitted by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan
Documents.

     Section 11.10 The Arrangers and Agents. Neither the Arrangers, the Syndication Agent,
nor any Co-Documentation Agent shall have any 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.

     Section 11.11 Filing of Proofs of Claim. In case of any Default or Event of Default
under Section 10.01(g), Section 10.01(h) or Section 10.01(i), the
Administrative Agent (regardless of whether the principal of any Loan or LC Exposure shall then be
due and payable and regardless of whether the Administrative Agent has made any demand on the Loan
Parties) shall be entitled and empowered, by intervention in such proceeding or otherwise:

          (a) to (i) file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans, LC Exposure and all other Indebtedness that is owing and unpaid and
(ii) 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, the Administrative Agent and their respective
agents and counsel and all other amounts due the Lenders, the Administrative Agent under
Section 3.05 and 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.

Each Lender hereby authorizes any custodian, receiver, assignee, trustee, conservator, sequestrator
or other similar official in any such judicial proceeding: (i) to make such payments to the
Administrative Agent; and (ii) if 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 3.05
and Section 12.03. Nothing contained herein shall be deemed to authorize the

Resolute Energy Corporation

Second Amended & Restated Credit Agreement

88

 

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 Indebtedness 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. Each Lender retains its right to file and prove a claim separately.

     Section 12.02 Waivers; Amendments.

          (a) No failure on the part of any Agent, any 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 Agents, each 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 Loan Party 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 any Agent, any Lender or any 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 of the Required Lenders,
or modify 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 Indebtedness hereunder or under any other Loan Document,
without the written consent of each Lender directly, adversely affected thereby, (iv) postpone the
scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest
thereon, or any fees payable hereunder, or any other Indebtedness 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 directly, adversely affected thereby,

obligations secured or guaranteed by the Security Instruments or the priority of payments set forth

adversely, directly affect any other secured party; provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of any Agent, any Issuing

          (c) To the extent that the Borrower or the Loan Parties fail to pay any amount required to be

any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or

     Section 12.04 Successors and Assigns.

          (a) 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 any Issuing Bank that issues any Letter of Credit), except that (i) the Loan Parties
may not assign or otherwise transfer (except as permitted under Section 9.11) any of their
rights or obligations hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Loan Parties without such consent shall be null and void) and (ii) 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 any 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, each
Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of
this Agreement.

          (b) (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 or delayed) of: (A) the Borrower,
provided that no consent of the Borrower shall be required for an assignment to a Lender,
an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is
continuing, any other assignee; and (B) the Administrative Agent, provided that no such
consent 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
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 $10,000,000, and the Commitments of any assigning Lender remaining a party hereto after
giving effect to the assignment shall be at least $10,000,000, unless, in each case, each of the
Borrower, the Administrative Agent otherwise consents, 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

Questionnaire and shall deliver notice of the Assignment and Assumption to the Borrower; (E)
in the case of an assignment to a CLO, the assigning Lender shall retain the sole right to approve
any amendment, modification or waiver of any provision of this Agreement, provided that the
Assignment and Assumption between such Lender and such CLO may provide that such Lender will not,
without the consent of such CLO, agree to any amendment, modification or waiver described in the
first proviso to Section 12.02(b) that affects such CLO; and (F) no such assignment shall
be made to the Borrower or any of the Borrower’s Subsidiaries or other Affiliates.

               (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 entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent, each 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, any Issuing Bank and any Lender, at any
reasonable time and from time to time upon reasonable prior notice.

               (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
shall already be a Lender hereunder), the processing and recordation fee referred to in Section
12.04(b) and any written consent to such assignment required by 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) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or any
Issuing Bank, sell participations to one or more banks or other financial investors (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 (A) such Lender’s obligations under this Agreement shall remain
unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (C) the Borrower, the Administrative Agent, each 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 and (D) such Participant agrees to be
bound by Section 12.11. 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 of the Loan
Documents described in the proviso to Section 12.02(b) that affects such Participant. In
addition such agreement must provide that the Participant be bound by the provisions of Section
12.03 and Section 12.11. 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 hereafter given. A Participant
that would be a Foreign Lender if it were a Lender shall not be entitled to the 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) 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 any pledge or
assignment to secure obligations to a Federal Reserve Bank, 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.

          (e) Notwithstanding any other provisions of this Section 12.04, no transfer or
assignment of the interests or obligations of any Lender or any grant of participations therein
shall be permitted if such transfer, assignment or grant would require the Loan Parties to file a
registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

     Section 12.05 Survival; Revival; Reinstatement.

          (a) All covenants, agreements, representations and warranties made by the Borrower 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, any 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. Subject to the
foregoing sentence, upon (i) repayment in full of the Loans and all interest thereon and other
amounts due and owing under this Agreement and all other Obligations (as defined in the Guaranty
and Collateral Agreement) then due and owing, (ii) the expiration or termination of the
Commitments, (iii) the expiration or termination of all Letters of Credit (or upon the providing of
collateral therefor satisfactory to the Issuing Bank in its absolute discretion), (iii) the
termination of the Hedging Agreements with the Secured Hedging Providers to the extent such Hedging
Agreements require any Loan Document or the Collateral to remain in effect, and (iv) the compliance
by the Loan Parties with the covenants and agreements set forth in the Guaranty and Collateral
Agreement, upon the written request of the Borrower and at the expense of the Borrower, (A) this
Agreement and the other Loan Documents shall terminate, (B) the Collateral thereunder shall be
released, and (C) the Administrative Agent shall provide to the Borrower reasonable releases of the
Collateral in recordable form (as necessary) and other reasonably requested confirmations or
evidence of termination and release.

          (b) To the extent that any payments on the Indebtedness 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 Indebtedness 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 shall take such action as may be reasonably requested
by the Administrative Agent or 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.

          (b) This Agreement, the other Loan Documents and any separate letter agreements with respect
to fees payable to the Arrangers and 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(a), 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 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 Hedging Agreements) at any time
owing by such Lender or Affiliate to or for the credit or the account of the Loan Parties or any
Restricted Subsidiary against any of and all the obligations of the Loan Parties or any Restricted
Subsidiary 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.

AND THEREOF AND APPLICABLE LAW, 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 12.13 No Third Party Beneficiaries. The agreement of the Lenders to make
Loans and each 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 Subsidiary
of the Borrower, 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, any Issuing Bank or any Lender for any reason whatsoever.
There are no third party beneficiaries of the rights of the Borrower under the Loan Documents.

     Section 12.14 Collateral Matters; Hedging Agreements; Treasury Management Agreements.
The benefit of the Security Instruments and of the provisions of this Agreement relating to any
Collateral securing the Indebtedness shall also extend to and be available to Secured Hedging

priorities set out in Section 10.02(c)) in respect of any Indebtedness of the Borrower or
any of its Restricted Subsidiaries which arises under any such Hedging 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 Hedging
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 Loan Parties may grant security interests, covering all
rights of the Loan Parties in Hedging Agreements with any Lender or Secured Hedging Provider, to
the Administrative Agent under the Security Instruments to secure the Indebtedness, notwithstanding
any restriction on such security interests under any Hedging Agreement.

     Section 12.15 US Patriot Act Notice. Each Lender hereby notifies the Loan Parties
that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record
information that identifies each Loan Party, which information includes the name and address of
each Loan Party and other information that will allow such Lender to identify each Loan Party in accordance
with the Patriot Act.

Credit Agreement, and
pursuant to an amendment to the Guaranty and Collateral Agreement dated as of the date hereof,
Resolute Aneth confirms that it is a Guarantor.

          (b) This Agreement amends and restates the Existing Credit Agreement in its entirety. On the
date of the initial funding of Loans hereunder, (i) each “Loan” (as defined in the Existing Credit
Agreement) outstanding under the Existing Credit Agreement shall be repaid in full with the
proceeds of such Loans, (ii) all other amounts outstanding under the Existing Credit Agreement
(including breakage costs due under Section 5.02 of the Existing Credit Agreement) shall be paid in
full with the proceeds of such Loans to the extent not otherwise paid by the Borrower on such date,
(iii) the “Commitments” (as defined in the Existing Credit Agreement) shall be terminated (except
as otherwise expressly provided in Section 12.05 of the Existing Credit Agreement with respect to
the survival of certain covenants and agreements made by the Borrower and/or its Affiliates in the
Existing Credit Agreement) and replaced with the Commitments hereunder, and (iv) the Existing
Letters of Credit shall be deemed to be issued under this Agreement. It is the intent of the
parties hereto that this Agreement neither constitute a novation of the obligations and liabilities
existing under the Existing Credit Agreement nor evidence termination of any such obligations and
liabilities and that this Agreement amend and restate in its entirety the Existing Credit Agreement
and hereafter evidence the obligations of the Borrower outstanding thereunder. The undersigned
waive any right to receive any notice of the termination of the “Commitments” (as defined in the
Existing Credit Agreement) and any right to receive any notice of prepayment of amounts owed under
the Existing Credit Agreement. Each “Lender” (as defined in the Existing Credit Agreement) hereby
agrees to return to the Borrower, with reasonable promptness, any note delivered by Resolute Aneth
to such Lender in connection with the Existing Credit Agreement.

     Section 12.17 No Fiduciary Duty. Each Lender and its respective Affiliates
(collectively, solely for purposes of this Section 12.17, the “Lenders”) may have economic
interests that conflict with those of the Loan Parties. Each Loan Party 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 Loan Parties, their partners or their Affiliates. Each Loan Party 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 Loan Parties, 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 Loan Party, or of any Loan Party’s
management, partners, creditors or other Affiliates, (c) no Lender has assumed a fiduciary
responsibility in favor of any Loan Party with respect to the transactions with Lenders
contemplated by the Financing 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 Loan Party
on other matters) and (d) such Loan Party has consulted its own legal and financial advisors to the
extent it deemed appropriate. Each Loan Party further acknowledges and agrees that it is
responsible for making its own independent judgment with respect to such transactions and the
process leading thereto. Each Loan Party agrees that it will not claim that any Lender owes a

fiduciary duty to such Loan Party in connection with the Financing Documents, any Hedging Agreement
or any Treasury Management Agreement or the process leading thereto.
