Exposure, including that under any then requested Letter of Credit, shall not exceed at any time
$1,000,000 and (iv) no Letter of Credit shall be issued in an amount less than $25,000.

          (e) In connection with the issuance, renewal or extension by the Lender of any Letter of
Credit pursuant to subsection (d) immediately above, the Borrower shall pay to the Lender a letter
of credit fee in an amount equal to the greater of (i) two and one-half percent (2.50%) per annum,
calculated on the basis of a year of 360 days, and actual days elapsed (including the first day but
excluding the last day), on the amount of the L/C Exposure under such Letter of Credit and for the
period for which such Letter of Credit is issued or renewed or extended and remains outstanding or
(ii) $750. Such fee with respect to each Letter of Credit

-18-

 

shall be payable quarterly in advance commencing on the date of issuance, renewal or extension
of the relevant Letter of Credit and continuing on the corresponding day of each third calendar
month thereafter. The Lender shall be obligated to refund the portion of any such fee previously
received upon early cancellation of the relevant Letter of Credit. The Borrower also agrees to pay
on demand to the Lender its customary letter of credit transaction fees and expenses, including
amendment fees, payable with respect to each Letter of Credit.

          (f) The Borrower agrees that the Lender shall not be responsible for, nor shall the
Obligations be affected by, among other things, (i) the validity or genuineness of documents or any
endorsements thereon presented in connection with any Letter of Credit, even if such documents
shall in fact prove to be in any and all respects invalid, fraudulent or forged, so long as the
Lender has no actual knowledge of any such invalidity, lack of genuineness, fraud or forgery prior
to the presentment for payment of a corresponding Letter of Credit or any draft thereunder or (ii)
any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other
Person to which any Letter of Credit may be transferred, or any claims whatsoever of the Borrower
against any beneficiary of any Letter of Credit or any such transferee. The Borrower further
acknowledges and agrees that the Lender shall be liable to the Borrower to the extent, but only to
the extent, of any direct, as opposed to consequential or punitive, damages suffered by the
Borrower as a result of the willful misconduct or gross negligence of the Lender in determining
whether documents presented under a Letter of Credit complied with the terms of such Letter of
Credit that resulted in either a wrongful payment under such Letter of Credit or a wrongful
dishonor of a claim or draft properly presented under such Letter of Credit. In the absence of
gross negligence or willful misconduct by the Lender, the Lender shall not be liable for any error,
omission, interruption or delay in transmission, dispatch or delivery of any message or advice,
however transmitted, in connection with any Letter of Credit. The Lender and the Borrower agree
that any action taken or omitted by the Lender under or in connection with any Letter of Credit or
the related drafts or documents, if done in the absence of gross negligence or willful misconduct,
shall be binding as among the Lender and the Borrower and shall not put the Lender under any
liability to the Borrower.

          (g) The Borrower shall provide to the Lender, immediately upon demand by the Lender, funds
sufficient to allow the Lender to pay any drawing by a beneficiary under a Letter of Credit.
Absent receipt of such funds prior to the Lender being obligated to pay the relevant drawing under
a Letter of Credit, the Lender shall make a Letter of Credit Payment in payment of such drawing.

          (h) Each Letter of Credit Payment shall be deemed to be a Loan by the Lender and shall be
evidenced by the Note and shall be payable by the Borrower upon demand by the Lender.

     2.2 Limitations on Interest Periods. Each Interest Period selected by the Borrower
(a) which commences on the last Business Day of a calendar month (or any day for which there is no
numerically corresponding day in the appropriate subsequent calendar month) shall end on the last
Business Day of the appropriate subsequent calendar month, (b) which would otherwise end on a day
which is not a Business Day shall end on the next succeeding Business Day (or, if such next
succeeding Business Day falls in the next succeeding calendar month, on the next preceding Business
Day), (c) which would otherwise end after the Commitment Termination

-19-

 

Date shall end on the Commitment Termination Date, and (d) shall have a duration of not less
than one month and, if any Interest Period would otherwise be a shorter period, the relevant Loan
shall be a Base Rate Loan during such period.

     2.3 Limitation on LIBO Rate Loans. Anything herein to the contrary notwithstanding,
no more than three separate LIBO Rate Loans shall be outstanding at any one time, with, for
purposes of this Section 2.3, all LIBO Rate Loans for the same Interest Period constituting
one LIBO Rate Loan. Anything herein to the contrary notwithstanding, if, on or prior to the
determination of any interest rate for any LIBO Rate Loan for any Interest Period therefor:

          (a) the Lender determines in good faith (which determination shall be conclusive, absent
manifest error) that quotations of interest rates for the deposits referred to in the definition of
“LIBO Rate” in Section 1.2 are not being provided in the relevant amounts or for the
relevant maturities for purposes of determining the rate of interest for such Loan as provided in
this Agreement; or

          (b) the Lender determines in good faith (which determination shall be conclusive, absent
manifest error) that the rates of interest referred to in the definition of “LIBO Rate” in
Section 1.2 upon the basis of which the rate of interest for such Loan for such Interest
Period is to be determined do not adequately and fairly cover the cost to the Lender of making or
maintaining such Loan for such Interest Period;

then the Lender shall give the Borrower notice thereof as promptly as practicable and so long as
such condition remains in effect, the Lender shall be under no obligation to make LIBO Rate Loans
or to convert Base Rate Loans into LIBO Rate Loans, and the Borrower shall, on the last day of the
then current Interest Period for each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan
or convert such Loan into a LIBO Rate Loan with amounts and maturities for which quotations are
provided, or convert such Loan into a Base Rate Loan in accordance with the provisions of
Section 2.12.

     2.4 Use of Loan Proceeds and Letters of Credit. (a) Proceeds of all Loans shall be
used solely by the Borrower (i) to pay expenses associated with the establishment of the Facility,
(ii) to develop or acquire Oil and Gas Properties, (iii) for working capital purposes or (iv) for
other general business purposes not otherwise prohibited under applicable provisions of this
Agreement.

          (b) Letters of Credit shall be issued solely for the account of the Borrower and may be used
for general business purposes not otherwise prohibited under applicable provisions of this
Agreement; provided, however, no Letter of Credit may be used in lieu or in support
of stay or appeal bonds or Obligations in respect of Commodity Hedge Agreements or Interest Rate
Hedge Agreements.

     2.5 Interest. Subject to applicable provisions of this Agreement (including those of
Section 2.16):

-20-

 

	 	(a)	 	interest on LIBO Rate Loans shall accrue and be
payable at the Adjusted LIBO Rate plus the Applicable Margin as
to LIBO Rate Loans; and
	 
	 	(b)	 	interest on Base Rate Loans shall accrue and be
payable at the Floating Rate.

Notwithstanding the foregoing, interest on past-due principal and, to the extent permitted by
applicable law, past-due interest and fees, shall accrue at the Default Rate and shall be payable
upon demand by the Lender at any time as to all or any portion of such interest. Interest provided
for herein shall be calculated on unpaid sums actually advanced and outstanding pursuant to the
terms of this Agreement and only for the period from the date or dates of such advances to, but not
including, the date or dates of repayment. In the event that the Borrower fails to select the
duration of any Interest Period for any LIBO Rate Loan within the time period and otherwise as
provided herein, such Loan (if outstanding as a LIBO Rate Loan) shall be automatically converted
into a Base Rate Loan on the last day of the then current Interest Period for such Loan or (if
outstanding as a Base Rate Loan) shall remain as, or (if not then outstanding) shall be made as, a
Base Rate Loan. Interest provided for herein shall be calculated on unpaid sums actually advanced
and outstanding pursuant to the terms of this Agreement and only for the period from the date or
dates of such advances to, but not including, the date or dates of repayment.

     2.6 Repayment of Loans and Interest. Accrued and unpaid interest on each outstanding
Base Rate Loan shall be due and payable quarterly commencing on the first day of August, 2008 and
continuing on the first day of each calendar quarter thereafter while any Base Rate Loan remains
outstanding, the payment in each instance to be the amount of interest which has accrued and
remains unpaid in respect of the relevant Loan. Accrued and unpaid interest on each outstanding
LIBO Rate Loan shall be due and payable on the earlier of (a) the last day of the Interest Period
for such LIBO Rate Loan or (b) if any Interest Period is of a duration longer than three months, on
the day of each third month of the relevant Interest Period corresponding to the day preceding the
initial day of such Interest Period and on the last day of the relevant Interest Period, the
payment in each instance to be the amount of interest which has accrued and remains unpaid in
respect of the relevant Loan. The Loan Balance, together with all accrued and unpaid interest
thereon as of such date, shall be due and payable on the Commitment Termination Date. At the time
of making each payment hereunder or under the Note, the Borrower shall specify to the Lender the
Loans or other amounts payable by the Borrower hereunder to which such payment is to be applied.
In the event the Borrower fails to so specify, or if an Event of Default has occurred and is
continuing, the Lender may apply such payment as it may elect in its discretion and in accordance
with the terms hereof.

     2.7 Outstanding Amounts. The outstanding principal balance of the Note reflected by
the notations of the Lender on its records shall be deemed rebuttably presumptive evidence of the
principal amount owing on the Note. The liability for payment of principal and interest evidenced
by the Note shall be limited to principal amounts actually advanced and outstanding pursuant to
this Agreement and interest on such amounts calculated in accordance with this Agreement.

-21-

 

     2.8 Taxes. (a) All payments required pursuant to this Agreement or the Note shall be
made without set-off or counterclaim in Dollars and in immediately available funds free and clear
of, and without deduction for, any Indemnified Taxes or Other Taxes; provided,
however that if the Borrower shall be required to deduct any Indemnified Taxes or Other
Taxes from such payments, then (i) the sum payable shall be increased by the amount (the
“Additional Amount”) necessary so that after making all required deductions (including
deductions applicable to additional sums described in this paragraph) the Lender receives an amount
equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall
make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law. In addition, to the extent not paid in
accordance with the preceding sentence, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

          (b) The Borrower shall indemnify the Lender for Indemnified Taxes and Other Taxes
paid by the Lender, provided, however, that the Borrower shall not in any event be
obligated to make payment to the Lender in respect of penalties, interest and other similar
liabilities attributable to such Indemnified Taxes or Other Taxes if such penalties, interest or
other similar liabilities are attributable to the gross negligence or willful misconduct of the
Lender.

          (c) If the Lender shall become aware that it is entitled to claim a refund from a Governmental
Authority in respect of Indemnified Taxes or Other Taxes paid by the Borrower pursuant to this
Section 2.8, including Indemnified Taxes or Other Taxes as to which it has been indemnified
by the Borrower, or with respect to which the Borrower has paid Additional Amounts pursuant to the
Loan Documents, it shall promptly notify the Borrower of the availability of such refund claim and,
if the Lender determines in good faith that making a claim for refund will not have an adverse
effect to its taxes or business operations, shall, within ten (10) days after receipt of a request
by the Borrower, make a claim to such Governmental Authority for such refund at the expense of the
Borrower. If the Lender receives a refund in respect of any Indemnified Taxes or Other Taxes paid
by the Borrower pursuant to the Loan Documents, it shall within thirty (30) days from the date of
such receipt pay over such refund to the Borrower (but only to the extent of Indemnified Taxes or
Other Taxes paid pursuant to the Loan Documents, including indemnity payments made or Additional
Amounts paid, by the Borrower under this Section 2.8 with respect to the Indemnified Taxes
or Other Taxes giving rise to such refund), net of all reasonable out of pocket expenses of the
Lender and without interest (other than interest paid by the relevant Governmental Authority with
respect to such refund).

          (d) If the Lender is or becomes eligible under any applicable law, regulation, treaty or other
rule to a reduced rate of taxation, or a complete exemption from withholding, with respect to
Indemnified Taxes or Other Taxes on payments made to it or for its benefit by the Borrower, the
Lender shall, upon the request, and at the cost and expense, of the Borrower, complete and deliver
from time to time any certificate, form or other document requested by the Borrower, the completion
and delivery of which are a precondition to obtaining the benefit of such reduced rate or
exemption, provided that the taking of such action by the Lender would not, in the
reasonable judgment of the Lender be disadvantageous or prejudicial to the Lender or inconsistent
with its internal policies or legal or regulatory restrictions. For any period with

-22-

 

respect to which the Lender has failed to provide any such certificate, form or other document
requested by the Borrower, the Lender shall not be entitled to any payment under this Section
2.8 in respect of any Indemnified Taxes or Other Taxes that would not have been imposed but for
such failure.

          (e) The Lender, shall (i) deliver to the Borrower, upon the written request of the Borrower,
two original copies of United States Internal Revenue Service Form W-9 or any successor form,
properly completed and duly executed by the Lender, certifying that the Lender is exempt from
United States backup withholding Tax on payments of interest made under the Loan Documents and (ii)
thereafter, at each time it is so reasonably requested in writing by the Borrower, deliver within a
reasonable time two original copies of an updated United States Internal Revenue Service Form W-9
or any successor form thereto.

     2.9 Time, Place and Method of Payments. All payments by the Borrower under this
Agreement or on the Note shall be deemed received on (i) receipt or (ii) the next Business Day
following receipt if such receipt is after 2:00 p.m., Central Standard or Central Daylight Savings
Time, as the case may be, on any Business Day, and shall be made to the Lender at the Principal
Office. Except as provided to the contrary herein, if the due date of any payment hereunder or
under the Note would otherwise fall on a day which is not a Business Day, such date shall be
extended to the next succeeding Business Day, and interest shall be payable for any principal so
extended for the period of such extension.

     2.10 Determinations of Applicable Amounts.

          (a) The Borrowing Base as of the Closing Date is acknowledged by the Borrower and the Lender
to be $4,500,000. Commencing on the first day of July, 2008 and continuing thereafter on the first
day of each calendar month through the Commitment Termination Date, the amount of the Borrowing
Base then in effect shall be reduced by the Monthly Reduction Amount, which Monthly Reduction
Amount as of the date of this Agreement is acknowledged by the Borrower and the Lender to be $0.

          (b) The Borrowing Base and the Monthly Reduction Amount shall be redetermined by the Lender on
September 1, 2008 and thereafter semi-annually (on each October 1 and April 1 prior to the
Commitment Termination Date) on the basis of information supplied by the Borrower in compliance
with the provisions of this Agreement, including Reserve Reports, and all other information
available to the Lender, such determination to be on the basis of the Lender’s reasonable credit
judgment. In addition, the Lender shall, in the normal course of business following a request of
the Borrower, redetermine the Borrowing Base and the Monthly Reduction Amount; provided,
however, (i) the Lender shall not be obligated to respond to more than one such request
during any calendar year and (ii) in no event shall the Lender be required to redetermine such
amounts more than twice (separately as to each amount) in any six-month period, including each
scheduled semi-annual redetermination provided for above. Notwithstanding the foregoing, the
Lender may, in the exercise of its reasonable credit judgment, redetermine the Borrowing Base and
the Monthly Reduction Amount at any time, provided that no engineering fee shall be payable to the
Lender for such unscheduled redetermination of the Borrowing Base.

-23-

 

          (c) Upon each determination of the Borrowing Base and the Monthly Reduction Amount, the Lender
shall notify the Borrower in writing of such determinations, and the amounts so communicated to the
Borrower shall become effective upon such notification and shall remain in effect until the next
subsequent determination of such amounts.

          (d) The Borrowing Base shall represent the determination by the Lender, in accordance with the
applicable definitions and provisions herein contained and the customary lending practices of the
Lender for loans of this nature, of the value, for loan purposes, of the Mortgaged Properties and
any other Oil and Gas Properties acceptable to the Lender. Furthermore, the Borrower acknowledges
that the determination of the Borrowing Base contains an equity cushion (market value in excess of
loan value), which is acknowledged by the Borrower to be essential for the adequate protection of
the Lender.

     2.11 Mandatory Prepayments. If at any time, as a result of the second sentence of
subsection (a) of Section 2.10, the sum of the Loan Balance and the L/C Exposure exceeds
the Commitment Amount then in effect, the Borrower shall, within fiveBusiness Days of receipt of
written notice from the Lender of such occurrence, prepay such portion of the Loan Balance and/or,
as provided below in this subsection (a), provide cash as Collateral so that the sum of the Loan
Balance and the L/C Exposure does not exceed the Commitment Amount then in effect. If at any time,
other than as a result of the second sentence of subsection (a) of Section 2.10, the sum of
the Loan Balance and the L/C Exposure exceeds the Commitment Amount then in effect, the Borrower
shall, at the option of the Borrower and within 10 days of receipt of written notice from the
Lender of such occurrence, (a) prepay the amount of such excess in three substantially equal
installment payments, each for application on the Loan Balance and then to provide cash as
Collateral for the L/C Exposure in the manner provided below in this Section 2.11, the
first of which being due on the 30th day following receipt by the Borrower of the
relevant written notice from the Lender, the second of which being due on the 60th day
following receipt by the Borrower of the relevant written notice from the Lender, and the third of
which being due on the 90th day following receipt by the Borrower of the relevant
written notice from the Lender, (b) provide, within 30 days of such election by the Borrower,
additional Collateral, of character and value satisfactory to the Lender in its sole discretion,
and/or cash as Collateral to secure the Obligations, by way of the execution and delivery to the
Lender of Security Documents in form and substance satisfactory to the Lender or (c) affect any
combination of the alternatives described in clauses (a) and (b) of this sentence and acceptable to
the Lender in its reasonable credit judgment. Any prepayment pursuant to the provisions of this
Section 2.11 or Section 6.4 shall be without premium or penalty and shall be
applied against the Loan Balance and accrued and unpaid interest thereon, and the amount of any
such prepayment applied against the Loan Balance may be reborrowed if otherwise available to the
Borrower pursuant to the terms of this Agreement. In the event that a mandatory prepayment is to
be made under this Section 2.11 and the Loan Balance is less than the amount required to be
prepaid, the Borrower shall repay the entire Loan Balance and, in accordance with the provisions of
the relevant Letter of Credit Applications executed by the Borrower or otherwise to the
satisfaction of the Lender, deposit with the Lender, as additional collateral securing the
Obligations, an amount of cash, in immediately available funds, equal to the L/C Exposure minus the
Commitment Amount. The cash deposited with the Lender in satisfaction of the requirement provided
in this Section 2.11 may be invested, at the sole discretion of the Lender and then only at
the express direction of the

-24-

 

Borrower as to investment vehicle and maturity (which shall be no later than the latest expiry
date of any then outstanding Letter of Credit), for the account of the Borrower in cash or cash
equivalent investments offered by or through the Lender.

     2.12 Voluntary Prepayments and Conversions of Loans. Subject to applicable provisions
of this Agreement, the Borrower shall have the right at any time or from time to time to prepay
Loans without prepayment penalty and to convert Loans of one type or with one Interest Period into
Loans of another type or with a different Interest Period; provided, however, that
(a) the Borrower shall give the Lender notice of each such prepayment or conversion of (i) all or
any portion of a LIBO Rate Loan no less than three Business Days prior to prepayment or conversion
or (ii) all or any portion of a Base Rate Loan no less than one Business Day prior to prepayment or
conversion, (b) any prepayment of any LIBO Rate Loan shall be in an amount of at least equal to
$100,000 and a multiple of $100,000, (c) the Borrower shall pay all accrued and unpaid interest on
the amounts prepaid or converted, (d) no such prepayment or conversion shall serve to postpone the
repayment when due of any Obligation or any installments thereof, and (e) the Borrower shall
reimburse the Lender, as provided in subsection (d) of Section 2.17, for losses, expenses
or costs directly attributable and incurred by the Lender pursuant to prepayment or conversion of a
Loan, or the failure of the Borrower to make any proposed prepayment or conversion. Any prepayment
pursuant to the provisions of this Section 2.12 shall be without premium or penalty and the
amount of any such prepayment applied against the Loan Balance may be reborrowed if otherwise
available to the Borrower pursuant to the terms of this Agreement.

     2.13 Commitment Fees. In addition to interest on the Note as provided herein and
other fees payable hereunder, and to compensate the Lender for maintaining funds available under
the Facility, the Borrower shall pay to the Lender, in immediately available funds, on the first
day of each calendar quarter during the Commitment Period, commencing on the first day of August,
2008, and on the Commitment Termination Date, a fee equal to the Applicable Commitment Fee
Percentage, calculated on the basis of a year of 365 or 366 days, as the case may be, and actual
days elapsed (including the first day, but excluding the last day), on the average daily amount of
the Available Commitment during the preceding quarterly or shorter period, as the case may be.
Commitment Fees shall be payable by the Borrower upon receipt of an invoice therefor or statement
thereof delivered by the Lender and shall be past due if not paid within ten days of receipt of
each such invoice or statement.

     2.14 Additional Fees. In addition to interest on the Note as provided herein and
other fees payable hereunder, the Borrower shall pay to the Lender, in immediately available funds
and at the times indicated with respect to each such fee, the following fees:

          (a) a fee in the amount of $22,500, payable contemporaneously with execution of this
Agreement;

          (b) an initial engineering review fee in the amount of $3,500, payable contemporaneously with
execution of this Agreement;

          (c) a fee in the amount equal to one-half of one percent (0.50%) multiplied by the amount of
(i) any increase to the Borrowing Base in effect on the Closing Date and (ii) each

-25-

 

increase to the Borrowing Base thereafter to an amount in excess of the highest Borrowing Base
previously in effect at any time payable, in each instance, at the time of each such increase; and

          (d) a fee in the amount of $3,500, payable with respect to each engineering review in
connection with each scheduled or Borrower requested redetermination of the Borrowing Base,
payable, in each instance, within ten days of receipt from the Lender of an invoice therefor.

Each fee payable under this Section 2.14 shall be fully earned upon payment and not subject
to any refund.

     2.15 Loans to Satisfy Obligations of Borrower. Upon a Default, the Lender may, but
shall not be obligated to, make Loans for the benefit of the Borrower and apply proceeds thereof to
the satisfaction of any condition, warranty, representation or covenant of the Borrower contained
in this Agreement or any other Loan Document in an aggregate principal amount, when taken with the
then existing sum of the Loan Balance and the L/C Exposure, not to exceed at any time the
Commitment Amount. Such Loans shall be evidenced by the Note and shall bear interest at the
Floating Rate, subject, however, to the provisions of Section 2.5 regarding
the accrual of interest at the Default Rate in certain circumstances.

     2.16 General Provisions Relating to Interest. (a) It is the intention of the parties
hereto to comply strictly with the usury laws of the State of Texas and the United States of
America. In this connection, there shall never be collected, charged, or received on the sums
advanced hereunder interest in excess of that which would accrue at the Highest Lawful Rate. The
Borrower agrees that, to the extent the Highest Lawful Rate is determined with reference to the
laws of the State to Texas, the Highest Lawful Rate shall be the “weekly” rate as defined in
Chapter 303 of the Texas Finance Code (Vernon’s 1999), provided that the Lender may, at its
election, substitute for the “weekly” rate the “annualized” or “quarterly” rate, as such terms are
defined in the aforesaid statute, upon the giving of notices provided for in such statute and
effective upon the giving of such notices. The Lender may also rely, to the extent permitted by
applicable laws of the State of Texas or the United States of America, on alternative maximum rates
of interest under other laws of the State of Texas or the United States of America applicable to
the Lender, if greater.

          (b) Notwithstanding anything herein or in the Note to the contrary, during any Limitation
Period, the interest rate to be charged on amounts evidenced by the Note shall be the Highest
Lawful Rate, and the obligation, if any, of the Borrower for the payment of fees or other charges
deemed to be interest under applicable law shall be suspended. During any period or periods of
time following a Limitation Period, to the extent permitted by applicable laws of the State of
Texas or the United States of America, the interest rate to be charged hereunder shall remain at
the Highest Lawful Rate until such time as there has been paid to the Lender (i) the amount of
interest in excess of that accruing at the Highest Lawful Rate that the Lender would have received
during the Limitation Period had the interest rate remained at the otherwise applicable rate, and
(ii) all interest and fees otherwise payable to the Lender but for the effect of such Limitation
Period.

-26-

 

          (c) If, under any circumstances, the aggregate amounts paid on the Note or under this
Agreement or any other Loan Document include amounts which by law are deemed interest and which
would exceed the amount permitted if the Highest Lawful Rate were in effect, the Borrower
stipulates that such payment and collection will have been and will be deemed to have been, to the
extent permitted by applicable laws of the State of Texas or the United States of America, the
result of mathematical error on the part of the Borrower and the Lender; and the Lender shall
promptly refund the amount of such excess (to the extent only of such interest payments in excess
of that which would have accrued and been payable on the basis of the Highest Lawful Rate) upon
discovery of such error by the Lender or notice thereof from the Borrower. In the event that the
maturity of any Obligation is accelerated, by reason of an election by the Lender or otherwise, or
in the event of any required or permitted prepayment, then the consideration constituting interest
under applicable laws may never exceed that payable on the basis of the Highest Lawful Rate, and
excess amounts paid which by law are deemed interest, if any, shall be credited by the Lender on
the principal amount of the Obligations, or if the principal amount of the Obligations shall have
been paid in full, refunded to the Borrower.

          (d) All sums paid, or agreed to be paid, to the Lender for the use, forbearance and detention
of the proceeds of any advance hereunder shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term hereof until paid in full so
that the actual rate of interest is uniform but does not exceed the Highest Lawful Rate throughout
the full term hereof.

     2.17 Yield Protection. (a) Without limiting the effect of the other provisions of
this Section 2.17 (but without duplication), the Borrower shall pay to the Lender from time
to time such amounts as the Lender may reasonably determine are necessary to compensate it for any
actual and reasonable Additional Costs incurred by the Lender;

          (b) Without limiting the effect of the other provisions of this Section 2.17 (but
without duplication), the Borrower shall pay to the Lender (or the Lender’s holding company) from
time to time on request such amounts as the Lender (or the Lender’s holding company) may determine
are necessary to compensate the Lender (or the Lender’s holding company) for any costs attributable
to the maintenance by the Lender (or the Applicable Lending Office), pursuant to any Regulatory
Change, of capital in respect of its Commitment, such compensation to include an amount equal to
any reduction of the rate of return on assets or equity of the Lender (or the Lender’s holding
company or any Applicable Lending Office) to a level below that which the Lender (or the Lender’s
holding company or any Applicable Lending Office) could have achieved but for such Regulatory
Change.

          (c) Without limiting the effect of the other provisions of this Section 2.17 (but
without duplication), in the event that any Requirement of Law or Regulatory Change or the
compliance by the Lender therewith shall (i) impose, modify or hold applicable any reserve, special
deposit or similar requirement against any Letter of Credit or obligation to issue Letters of
Credit or (ii) impose upon the Lender any other condition regarding any Letter of Credit or
obligation to issue Letters of Credit, and the result of any such event shall be to increase the
cost to the Lender of issuing or maintaining any Letter of Credit or obligation to issue Letters of
Credit or any liability with respect to Letter of Credit Payments, or to reduce any amount
receivable in connection therewith, then upon demand by the Lender, the Borrower shall pay to

-27-

 

the Lender, from time to time as specified by the Lender, additional amounts which shall be
sufficient to compensate the Lender for such increased cost or reduced amount receivable.

          (d) Without limiting the effect of the other provisions of this Section 2.17 (but
without duplication), the Borrower shall pay to the Lender such amounts as shall be sufficient in
the reasonable opinion of the Lender to compensate it for any actual and reasonable loss, cost or
expense incurred by and as a result of:

	 	(i)	 	any payment, prepayment or
conversion by the Borrower of a LIBO Rate Loan on a
date other than the last day of an Interest Period for
such Loan; or
	 
	 	(ii)	 	any failure by the Borrower to
borrow a LIBO Rate Loan or to convert a Base Rate Loan
into a LIBO Rate Loan on the date for such borrowing or

prepaid, converted or not borrowed or converted for the period from the date of such payment,
prepayment, conversion or failure to borrow or convert to the last day of the then current Interest

Letters of Credit or such other obligations, and the additional amounts required to compensate the

other circumstance arising after the Closing Date affecting the Lender, the Lender (a) incurs
Additional Costs based on or measured by the excess above a level, as prescribed from time to time

LIBO Rate Loan is determined as provided in this Agreement or a category of extensions of credit or

none of the letters in lieu of transfer or division orders provided by the Borrower pursuant to the
provisions of Section 3.1(f) or Section 5.7 will be sent to the addressees thereof
unless an Event of Default has occurred and is continuing, at which time the Lender may, at its
option, and in addition to the exercise of any of its other rights and remedies, send any or all of
such letters.

     2.21 Power of Attorney. The Borrower hereby designates the Lender as its agent and
attorney-in-fact, to act in its name, place and stead solely for the purpose of completing and,

of Section 3.1(f) or Section 5.7, including completing any blanks contained in such
letters and attaching exhibits thereto describing the relevant Collateral. The Borrower hereby
ratifies and confirms all that the Lender shall lawfully do or cause to be done by virtue of this
power of attorney and the rights granted with respect to such power of attorney. This power of
attorney is coupled with the interests of the Lender in the Collateral, shall commence and be in
full force and effect as of the Closing Date and shall remain in full force and effect and shall be
irrevocable so long as any Obligation remains outstanding or unpaid or any Commitment exists. The
powers conferred on the Lender by this appointment are solely to protect the interests of the
Lender and any other Approved Hedge Counterparties under the Loan Documents with respect to the
Borrower’s assignment of production proceeds under certain of the Security Documents and shall not
impose any duty upon the Lender to exercise any such powers. The power of attorney herein is
expressly limited to the rights and powers set forth herein and no additional rights or powers are
herein created or implied. The Lender shall be accountable only for amounts that it

-29-

 

actually receives as a result of the exercise of such powers and shall not be responsible to
the Borrower or any other Person for any act or failure to act with respect to such powers, except

     2.22 Security Interest in Accounts; Right of Offset. As security for the payment and
performance of the Obligations, the Borrower hereby transfers, assigns, and pledges to the Lender
and grants to the Lender a security interest in all funds of the Borrower now or hereafter or from
time to time on deposit with the Lender, with such interest of the Lender to be retransferred,
reassigned and/or released at the expense of the Borrower upon payment in full and complete
performance by the Borrower of all Obligations. All remedies as secured party or assignee of such
funds shall be exercisable by the Lender upon the occurrence of any Event of Default, so long as
such Event of Default is continuing and has neither been cured nor waived, regardless of whether
the exercise of any such remedy would result in any penalty or loss of interest or profit with
respect to any withdrawal of funds deposited in a time deposit account prior to the maturity
thereof. Furthermore, the Borrower hereby grants to the Lender the right, exercisable at such time
as any Obligation shall mature, whether by acceleration of maturity or otherwise, of offset or
banker’s lien against all funds of the Borrower now or hereafter or from time to time on deposit
with the Lender, regardless of whether the exercise of any such remedy would result in any penalty
or loss of interest or profit with respect to any withdrawal of funds deposited in a time deposit
account prior to the maturity thereof.

elsewhere herein, all of which are hereby expressly waived by the Borrower and (ii) the Commitment

waived nor cured, (i) the Lender may, by notice in writing to the Borrower, declare all Obligations
under the Loan Documents immediately due and payable, without presentment, demand, protest, notice
of protest, default, or dishonor, notice of intent to accelerate maturity, notice of acceleration

MISCELLANEOUS

     8.1 Assignments; Participations.

          (a) The Borrower may not assign any of its rights or delegate any of its obligations under any
Loan Document without the prior consent of the Lender.

          (b) With the consent of the Borrower (which shall not be unreasonably withheld or delayed),
Lender may assign to one or more assignees all or a portion of its rights and obligations under
this Agreement; provided, however, (i) such consent of the Borrower shall not be
required when a Default or an Event of Default shall have occurred and is continuing, (ii) such
consent of the Borrower shall not be required with respect to an assignment from the

-53-

 

Lender to an Affiliate of the Lender and (iii) such consent of the Borrower shall not be
required with respect to an assignment from the Lender to one or more Approved Funds.

          (c) The Lender may transfer, grant or assign participations in all or any portion of its
interests hereunder to any Person pursuant to this Section 9.1(c), provided that
the Lender shall remain the “Lender” for all purposes of this Agreement and the transferee of such
participation shall not constitute a “Lender” hereunder. In the case of any such participation,
the participant shall not have any rights under any Loan Document, the rights of the participant in
respect of such participation to be against the Lender as set forth in the agreement with the
Lender creating such participation, and all amounts payable by the Borrower hereunder shall be
determined as if the Lender had not sold such participation.

          (d) The Lender may furnish any information concerning the Borrower in the possession of the
Lender from time to time to assignees and participants and prospective assignees and participants.

          (e) Notwithstanding anything in this Section to the contrary, the Lender may assign and pledge
the Note or any interest therein to any Federal Reserve Bank or the United States Treasury as
collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve
System and any operating circular issued by such Federal Reserve System and/or such Federal Reserve
Bank. No such assignment or pledge shall release the Lender from its obligations hereunder.

          (f) Notwithstanding any other provisions of this Section 9.1, no transfer or
assignment of the interests or obligations of the Lender or grant of participations therein shall
be permitted if such transfer, assignment or grant would require the Borrower to file a
registration statement with the Securities and Exchange Commission or any successor Governmental
Authority or qualify the Loans under the “Blue Sky” laws of any state.

     8.2 Survival of Representations, Warranties, and Covenants. All representations and
warranties of the Borrower and all covenants and agreements herein made shall survive the execution
and delivery of the Note and the Security Documents and shall remain in force and effect so long as
any Obligation is outstanding or any Commitment exists.

     8.3 Notices and Other Communications. Except as to oral notices expressly authorized
herein, which oral notices shall be confirmed in writing, all notices, requests and communications
hereunder shall be in writing (including facsimile or other electronic form). Unless otherwise
expressly provided herein, any such notice, request, demand, or other communication shall be deemed
to have been duly given or made when delivered by hand, or, in the case of delivery by mail, five
days after being deposited in the mail, certified mail, return receipt requested, postage prepaid,
or, in the case of facsimile notice, when receipt thereof is acknowledged orally or by written
confirmation report, addressed as follows:

Attention: E. Sven Hagen, Chairman and CEO

Facsimile: (805) 566-2917

Any party may, by proper written notice hereunder to the others, change the individuals or
addresses to which such notices to it shall thereafter be sent.

     8.4 Parties in Interest. Subject to the restrictions on changes in structure set
forth in Section 6.10 and other applicable restrictions contained herein, all covenants and
agreements herein contained by or on behalf of the Borrower or the Lender shall be binding upon and
inure to the benefit of the Borrower or the Lender, as the case may be, and their respective
successors and permitted assigns.

     8.5 Renewals; Extensions. All provisions of this Agreement relating to the Note shall
apply with equal force and effect to each promissory note hereafter executed which in whole or in
part represents a renewal or extension of any part of the Indebtedness of the Borrower under this
Agreement, the Note or any other Loan Document.

     8.6 Rights of Third Parties. All provisions herein are imposed solely and exclusively
for the benefit of the Lender, any other Approved Hedge Counterparties and the Borrower. No other
Person shall have any right, benefit, priority or interest hereunder or as a result hereof or have
standing to require satisfaction of provisions hereof in accordance with their terms.

     8.7 No Waiver; Rights Cumulative. No course of dealing on the part of the Lender or
its officers or employees, nor any failure or delay by the Lender with respect to exercising any of
its rights under any Loan Document shall operate as a waiver thereof. The rights of the Lender
under the Loan Documents shall be cumulative and the exercise or partial exercise of any such right
shall not preclude the exercise of any other right. Neither the making of any Loan nor the
issuance of any Letter of Credit shall constitute a waiver of any of the covenants, warranties or
conditions of the Borrower contained herein. In the event the Borrower is unable to satisfy any
such covenant, warranty or condition, neither the making of any Loan nor the issuance of any Letter
of Credit shall have the effect of precluding the Lender from thereafter declaring such inability
to be an Event of Default as hereinabove provided.

-55-

 

     8.8 Survival Upon Unenforceability. In the event any one or more of the provisions
contained in any of the Loan Documents or in any other instrument referred to herein or executed in
connection with the Obligations shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any
other provision of any Loan Document or of any other instrument referred to herein or executed in
connection with such Obligations.

     8.9 Amendments; Waivers. Neither this Agreement nor any provision hereof may be
amended, waived, discharged or terminated orally, but only by an instrument in writing signed by
the party against whom enforcement of the amendment, waiver, discharge or termination is sought.
Subject to the preceding sentence, any provision of this Agreement or any other Loan Document may
be amended, modified or waived by the Borrower and the Lender.

     8.10 Controlling Agreement. In the event of a conflict between the provisions of this
Agreement and those of any other Loan Document, the provisions of this Agreement shall control.

     8.11 Disposition of Collateral. Except as expressly provided to the contrary in this
Agreement, notwithstanding any term or provision, express or implied, in any of the Security
Documents, the realization, liquidation, foreclosure or any other disposition on or of any or all
of the Collateral shall be in the order and manner and determined in the sole discretion of the
Lender; provided, however, that in no event shall the Lender violate applicable law
or exercise rights and remedies other than those provided in such Security Documents or otherwise
existing at law or in equity.

     8.12 Governing Law. This Agreement and the Note shall be deemed to be
contracts made under and shall be construed in accordance with and governed by the laws of the
State of Texas, without giving effect to principles thereof relating to conflicts of law.

     8.13 Waiver of Rights to Jury Trial. The Borrower and the Lender hereby
knowingly, voluntarily, intentionally, irrevocably and unconditionally waive all rights to trial by
jury in any action, suit, proceeding, counterclaim or other litigation that relates to or arises
out of this Agreement or any other Loan Document or the acts or omissions of the Lender in the
enforcement of any of the terms or provisions of this Agreement or any other Loan Document or
otherwise with respect thereto. The provisions of this Section 8.13 are a material
inducement for the Lender to enter into this Agreement.

     8.14 Jurisdiction and Venue. All actions or proceedings with respect to,
arising directly or indirectly in connection with, out of, related to or from this Agreement or any
other Loan Document may be litigated, at the sole discretion and election of the Lender, in courts
having situs in Houston, Harris County, Texas. In such regard, the Borrower hereby submits to the
jurisdiction of any local, state or federal court located in Houston, Harris County, Texas, and
hereby waives any rights it may have to transfer or change the jurisdiction or 

-56-

 

venue of any litigation brought against it by the Lender in accordance with this
Section 8.14.

     8.15 Integration. This Agreement and the other Loan Documents
constitute the entire agreement between the parties hereto and thereto with respect to the subject
hereof and thereof and shall supersede any prior agreement between the parties hereto and thereto,
whether written or oral, relating to the subject hereof and thereof, including any commitment
letter or term sheet. Furthermore, in this regard, this Agreement and the other written Loan
Documents represent, collectively, the final agreement between the parties hereto and thereto and
may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of such
parties. There are no unwritten oral agreements between such parties.

     8.16 Waiver of Punitive and Consequential Damages. Each of the Borrower
and the Lender hereby knowingly, voluntarily, intentionally and irrevocably (A) waives, to the
maximum extent it may lawfully and effectively do so, any right it may have to claim or recover, in
any dispute based hereon, or directly or indirectly at any time arising out of, under or in
connection with the Loan Documents or any transaction contemplated thereby or associated therewith,
before or after maturity, any special, exemplary, punitive or consequential damages, or damages
other than, or in addition to, actual damages and (b) acknowledges that it has been induced to
enter into this Agreement, the other Loan Documents and the transactions contemplated hereby and
thereby by, among other things, the mutual waivers and certifications contained in this Section
8.16.

     8.17 Counterparts. For the convenience of the parties, this Agreement may be executed
in multiple counterparts and by different parties hereto in separate counterparts, each of which
for all purposes shall be deemed to be an original, and all such counterparts shall together
constitute but one and the same Agreement and shall be enforceable as of the date hereof upon the
execution of one or more counterparts hereof by each of the parties hereto. In this regard, each
of the parties hereto acknowledges that a counterpart of this Agreement containing a set of
counterpart execution pages reflecting the execution of each party hereto shall be sufficient to
reflect the execution of this Agreement by each party hereto and shall constitute one instrument.

     8.18 USA Patriot Act Notice. The Lender hereby notifies the Borrower that, pursuant
to the requirements of the USA Patriot Act, it is required to obtain, verify and record information
that identifies the Borrower, which information includes the name and address of the Borrower and
other information that will allow the Lender to identify the Borrower in accordance with the USA
Patriot Act.

     8.19 Tax Shelter Regulations. The Borrower does not intend to treat the Loans and
related transactions hereunder and under the other Loan Documents as a “reportable transaction”
(within the meanings under current Treasury Regulation Section 1.6011-4 and Proposed Treasury
Regulation Section 1.6011-4, promulgated on November 1, 2006). In the event the Borrower
determines to take any action inconsistent with the foregoing statement, it will

-57-

 

promptly notify the Lender thereof. If the Borrower so notifies the Lender, the Borrower
acknowledges that the Lender may treat the Loans and related transactions hereunder and under the
other Loan Documents as part of a transaction that is subject to current Treasury Regulation
Section 301.6112-1 or Proposed Treasury Regulation Section 301.6112-1, promulgated on November 1,
2006, and, in such case, the Lender will maintain the lists and other records required, if any, by
such Treasury Regulations.

Texas Capital Bank, N.A.

Attention: Energy Banking

One Riverway, Suite 2450

Houston, Texas 77056

	 	Re: 	 	 Credit Agreement dated June ___, 2008, by and between Legacy Energy,
Inc., a Delaware corporation, and Texas Capital Bank, N.A., a national banking
association (as amended, supplemented, restated or otherwise modified from time
to time, the “Credit Agreement”)

Ladies and Gentlemen:

     We have acted as special California counsel to Legacy Energy, Inc., a Delaware corporation
(the “Borrower”), in connection with the transactions contemplated in the Credit Agreement.
This opinion is delivered pursuant to Section 3.1(n) of the Credit Agreement, and the Lender is
hereby authorized to rely upon this opinion in connection with the transactions contemplated in the
Credit Agreement. For convenience, each capitalized term used but not defined herein shall have
the meaning assigned to such term in the Credit Agreement, unless expressly provided to the
contrary herein.

     In our representation of the Borrower, we have examined an executed counterpart or a copy of
an executed counterpart of each of the following (collectively, the “Loan Documents”), each
of which is dated of even date herewith:

     (a) the Credit Agreement;

     (b) the Note; and

     (c) Deed of Trust, Security Agreement, Financing Statement and Assignment of Production from
the Borrower in favor of Jonathan Gregory, Trustee for the benefit of the Lender (the “Deed of
Trust”).

     In making such examinations, we have, with your permission, assumed:

     (i) the genuineness of all signatures to the Loan Documents;

IV-i 

 

     (ii) the authenticity of all documents submitted to us as originals and the conformity with
the originals of all documents submitted to us as copies;

     (iii) that each party to the Loan Documents is duly organized, legally existing and in good
standing under the laws of its jurisdiction of organization and is either qualified to do business
in California or is a foreign lending institution and is involved only in those activities defined
in California Corporations Code Section 191(d);

     (iv) that the Lender and Borrower are each authorized and has the power to enter into and
perform its obligations under the Credit Agreement and the other Loan Documents to which it is a
party;

     (v) the due authorization, execution and delivery of all Loan Documents by each party thereto;

     (vi) that the Borrower has good and marketable title to all Mortgaged Property (as such term
is defined in the Real Property Security Documents, respectively) and rights in the Collateral (as
such term is defined in the Security Agreement); and

     (vii) the truth and accuracy of the factual representations and warranties made and contained
in each of the Loan Documents, and that they will remain true and accurate as of the date of
recordation of the Deed of Trust. We have not independently investigated or determined such facts.

     Based upon the foregoing and subject to the qualifications set forth herein, we are of the
opinion that:

     1. The Loan Documents constitute legal, valid and binding obligations of the
Borrower enforceable against the Borrower in accordance with their respective terms.

     2. The form of the Deed of Trust and the forms of the descriptions in the Deed
of Trust of the Mortgaged Property (as defined therein) satisfy all applicable laws
of the State of California to create the lien upon the Collateral as provided for in
such Deed of Trust and are legally sufficient under the laws of the State of
California to create the lien upon the Collateral as provided for in such Deed of
Trust.

     3. The Deed of Trust (a) creates liens upon and security interests in all
Mortgaged Property (as defined therein) to secure the Indebtedness (as defined
therein) and (b) provides for nonjudicial foreclosure remedies customarily used in
the State of California.

     4. The Deed of Trust is in satisfactory form for filing and recording in the
office described in paragraph 5.

     5. The filing and/or recording, as the case may be, of a counterpart of the
Deed of Trust in the office of the county clerk/recorder of each county in the

IV-ii 

 

State of California in which any portion of the Mortgaged Property (as defined
in the Deed of Trust) is located is the only recording or filing in the State of
California necessary to perfect the liens and security interests created by the Deed
of Trust or to permit the Lender to enforce in the State of California its rights
under the Deed of Trust.

     6. No state or local mortgage registration tax stamp tax or other similar fee,
tax or governmental charge (other than statutory filing and recording fees to be
paid upon filing) is required to be paid to the State of California or any
subdivision thereof, in connection with the execution, delivery, filing or recording
of the Deed of Trust.

     The opinions expressed herein are subject to the following qualifications and limitations:

     A. We are licensed to practice law only in the State of California and other
jurisdictions the laws of which are not applicable to the opinions expressed herein;
accordingly, the foregoing opinions are limited solely to the laws of the State of
California and applicable United States federal law.

     B. The validity, binding effect and enforceability of the Loan Documents may be
limited or affected by bankruptcy, insolvency, moratorium, reorganization or other
similar laws affecting rights of creditors generally, including, without limitation,
statutes or rules of law which limit the effect of waivers of rights by a debtor or
grantor; provided, however, that the limitations and other effects
of such statutes or rules of law upon the validity and binding effect of the Loan
Documents should not differ materially from the limitations and other effects of
such statutes or rules of law upon the validity and binding effect of assignments
and security documents generally.

     C. The enforceability of the obligations of the Borrower under the Loan
Documents is subject to general principles of equity (whether such enforceability is
considered in a suit in equity or at law).

     D. We express no opinion as to the condition of title to or ownership of any of
the Collateral.

     E. The enforceability of the Deed of Trust is subject to the qualification that
certain rights, remedies, waivers and other provisions of such Deed of Trust may be
rendered ineffective, or limited, by applicable State laws or judicial decisions
governing such rights, remedies, waivers and provisions, but the inclusion of such
rights, remedies, waivers and provisions does not affect the validity or
enforceability of the other provisions thereof and in the event the Borrower does
not comply with the material terms of the Loan Documents, the Trustee or Lender may
exercise remedies that would normally be available under State law to a secured
lender provided it proceeds in accordance with State law. Without limiting the
generality of the preceding qualification, we advise you that:

IV-iii 

 

	 	(1)	 	limitations exist on the form of action and the
order in which remedies may be exercised under the Deed of
Trust, in particular where a single debt is secured by both real
and personal property. If a creditor wishes to exercise
judicial remedies with regard to the personal property the
creditor may be required to first complete all judicial
foreclosures on real property and fixtures or to include all as
security in a single judicial foreclosure;
	 
	 	(2)	 	limitations on the procedure for obtaining, and
the amount of, a deficiency judgment against the Borrower are
imposed by California Code of Civil Procedure §§ 580a, 580b,
580d, 726, 726.5 and 736 if the Deed of Trust is foreclosed in
the manner of a mortgage;
	 
	 	(3)	 	the amount necessary to redeem property sold
following judicial foreclosure proceedings is limited to the
amounts specified in California Code of Civil Procedure §§ 726
and 729.06 through 729.08;
	 
	 	(4)	 	insofar as the Deed of Trust secures future
advances, the lien of the Deed of Trust as to a future advance
will be entitled to priority over liens first appearing of
record after the date of recording of such Deed of Trust, to the
extent of the Collateral covered thereby, but prior to the date
on which such advance is made, so long as the Lender was legally
bound to make the advance;
	 
	 	(5)	 	insofar as the Deed of Trust encumbers
after-acquired real property of the Borrower not described in
the Deed of Trust, such encumbrance may not be perfected without
recordation of appropriate supplements describing the new
after-acquired property as Collateral.

     F. With respect to the opinion in paragraph 4, we have only reviewed
the requirements of the laws of the State of California as to form
necessary for filing and recording of the Deed of Trust. We have not
reviewed requirements of laws of local jurisdictions of the State of
California as to form, if any.

     G. The opinions rendered herein are given without regard to any
choice of law rules, and further, we provide no opinion as to what
law governs the Deed of Trust.

     This opinion is furnished for the benefit of the Lender and any transferee or assignee of the
Lender in connection with the transactions contemplated by the Credit Agreement and the

IV-iv 

 

other Loan Documents and is not to be quoted in whole or in part or otherwise referred to or
disclosed to any other person or entity or in any other transaction.

Very truly yours,

Inc., a Delaware corporation, and Texas Capital Bank, N.A., a national banking
association (as amended, supplemented, restated or otherwise modified from time

Ladies and Gentlemen:

     We have acted as counsel to Legacy Energy, Inc., a Delaware corporation (the
“Borrower”), in connection with the transactions contemplated in the Credit Agreement.
This opinion is delivered pursuant to Section 3.1(n) of the Credit Agreement, and the Lender is
hereby authorized to rely upon this opinion in connection with the transactions contemplated in the
Credit Agreement. For convenience, each capitalized term used but not defined herein shall have
the meaning assigned to such term in the Credit Agreement, unless expressly provided to the
contrary herein.

(items (i) through (iv) are collectively hereinafter referred to as the “Supporting

Production in favor of Jonathan Gregory, Trustee for the benefit of the Lender, and the Act of
Mortgage, Pledge, Security Agreement and Assignment of Production in favor of the Lender, for the
limited purpose of rendering our opinion that the execution and delivery of same are within the
power of the Borrower and have been duly executed and authorized by all necessary corporate action
by the Borrower.

          Finally, in rendering our opinion, we have also examined originals or copies, certified to
our satisfaction, of such public records and certificates of representatives of the Borrower, and
such other documents as we have deemed necessary for the purposes of the opinions herein
expressed. As to any facts material to our opinion, we have relied, with your consent, and
without independent inquiry or investigation, upon the representations and warranties of the
Borrower made in the Loan Documents as to factual matters (but not as to matters of law) and the
Officer’s Certificate.

     B. Assumptions. In making such examinations, we have, with your permission, assumed:

     (i) the genuineness of all signatures to the Loan Documents other than those of the officers

franchises, leases, plans, specifications, operating agreements, service contracts, contract rights

or encumbrance as contemplated by the Security Agreement, such consent has been obtained;

     (ix) that the Borrower has good and marketable title to all Mortgaged Properties and rights in
the Collateral (as such term is defined in the Security Agreement);

     (x) that the Loans are made to the Borrower and the Letters of Credit are issued for the
account of the Borrower by the Lender in accordance with the Loan Documents;

and obtaining of Letters of Credit thereunder, the execution and delivery by the Borrower of the
other Loan Documents to which the Borrower is a party, and the payment and performance by the
Borrower of all Obligations under the Credit Agreement and the other Loan Documents to which the
Borrower is a party, are within the power of the Borrower, have been duly authorized by all
necessary corporate action by the Borrower, and do not (a) contravene or conflict with any
Requirement of Law, (b) to our knowledge, contravene or conflict with any indenture, instrument or
other agreement to which the Borrower is a party or by which any Property of the Borrower may be
presently bound or encumbered or (c) to our knowledge, result in or require the creation or
imposition of any Lien upon any Property of the Borrower other than as contemplated by the Loan
Documents.

     (iii) The execution and delivery of the Deed of Trust, Security Agreement, Financing
Statement and Assignment of Production in favor of Jonathan Gregory, Trustee for the benefit of
the Lender and the Act of Mortgage, Pledge, Security Agreement and Assignment of

V-iii 

 

Production in favor of the Lender are within the power of the Borrower and the same have been
duly executed and authorized by all necessary corporate action by the Borrower.

     (iv) The Loan Documents constitute legal, valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their respective terms.

     (v) Subject to the limitations and qualification set forth herein, the Security Agreement
creates security interests in all Collateral (as defined therein) to secure the Secured Obligations

     (vi). The form of the Financing Statement is in proper form for filing and upon filing with
the Office of the Delaware Secretary of State will, with the exception of the creation of a
perfected security interest in oil, gas and other minerals before extraction, oil, gas and other
minerals as extracted, or accounts arising out of the sale at the wellhead or minehead of oil, gas,
or other minerals in which Borrower has an interest prior to extraction of the oil, gas, or other
minerals, create a perfected security interest in the Collateral, to the extent that a security
interest may be perfected by the filing of a UCC-1 Financing Statement in the State of Delaware.

     (vii) The filing of a counterpart of the Financing Statement with the Secretary of State of
the State of Delaware is the only recording or filing in the State of Delaware necessary to perfect
the security interests created by the Security Agreement.

     (viii) The Borrower is not an “investment company” or an “affiliate person” of an “investment
company” within the meaning of the Investment Company Act of 1940, as amended.

     D. Qualifications and Limitations. The opinions expressed herein are subject to the
following qualifications and limitations:

     (i) No opinion is given with respect to any document other than the Loan Documents (as the
term is defined above), even if such other documents are referenced or described in the Loan
Documents.

     (ii) No opinion is given as to whether a court would limit the exercise or enforcement of
rights or remedies under the Loan Documents (a) in the event of any default by any person under the
Loan Documents or any related agreement or instrument if it is determined that such default is not
material or if such exercise or enforcement is not reasonably necessary for a creditor’s
protection, or (b) if the exercise or enforcement thereof under the circumstances would violate an
implied covenant of good faith and fair dealing.

     (iii) No opinion is given with respect to (a) the power or authority of the Lender to enter
into or perform its obligations pursuant to the Loan Documents or of any party to otherwise act in
accordance with the terms of any agreement to which it is a party; (b) whether multiple remedies
may be pursued concurrently; (c) compliance by the Lender with any federal or state banking law,
rule, regulation or restriction; and (d) the enforceability of obligations set forth in documents
upon parties who are not signatories to such documents.

V-iv 

 

     (iv) No opinion is given with respect to: (a) the right, title or interest of Borrower in or
to any property, real or personal, or the freedom from any security interest, lien, charge or
encumbrance thereon; (b) the creation, existence, attachment, enforceability or perfection of any
lien on or security interest in any real property; (c) the priority of any lien on or security
interest in any Collateral or the accuracy or sufficiency of the description thereof in any of the
Loan Documents or in the Financing Statement; or (d) the enforceability of any provisions of the
Loan Documents that purport to (1) prospectively release a party with respect to a liability or (2)
require the parties to negotiate in good faith or to mutually agree on any terms and conditions.

     (v) No opinion is given with respect to the enforceability of any provision of the Loan
Documents waiving any rights or remedies under applicable law, imposing penalties, forfeitures,
increased interest rates and/or late payment charges upon delinquency in payment or the occurrence
of a default, or any provisions which may grant Lender the right to obtain attorneys’ fees and
other costs incurred which a court determines to be unreasonable or excessive.

     (vi) Certain of the remedial provisions of the Loan Documents may be limited or rendered
unenforceable by laws governing them or by public policy considerations. However, the
unenforceability referred to in this paragraph (D)(vi) will not render the Loan Documents invalid
as a whole nor preclude judicial enforcement of the repayment or acceleration of principal and
interest under the Loan Documents or the foreclosure on Collateral under the Security Agreement in
the event of a breach of a provision of the Loan Documents, assuming that Lender exercises its
rights and remedies in a commercially reasonable manner.

     (vii) We express no opinion as to the condition of the title to or ownership of any of the
Collateral or Mortgaged Properties.

     (viii) In connection with this opinion, we express legal conclusions based solely on the laws
of the State of Texas, the Delaware Act, the Delaware UCC, and applicable United States federal
statutory law of general application and, accordingly, we express no opinion as to the laws of any
other state or jurisdiction.

     (ix) No opinion is expressed as to the enforceability of any remedy set forth in the Loan
Documents that requires either the invocation of the jurisdiction of the courts of Louisiana or
California or enforcement within Louisiana or California.

     (x) The validity, binding effect and enforceability of the Loan Documents may be limited or
affected by bankruptcy, insolvency, moratorium, reorganization or other similar laws affecting
rights of creditors generally, including, without limitation, statutes or rules of law which limit
the effect of waivers of rights by a debtor or grantor; provided, however, that the
limitations and other effects of such statutes or rules of law upon the validity and binding effect
of the Loan Documents should not differ materially from the limitations and other effects of such
statutes or rules of law upon the validity and binding effect of assignments and security documents
generally.

V-v 

 

     (xi) The enforceability of the obligations of the Borrower under the Loan Documents is subject
to general principles of equity (whether such enforceability is considered in a suit in equity or
at law).

     (xii) We express no opinion with regard to state or federal securities laws or regulations.

     (xiii) We express no opinion as to state or federal regulatory requirements or restrictions
imposed on financial institutions or their affiliates (federally-insured or otherwise).

     (xiv) We express no opinion with respect to the effect of the failure of the Lender to enforce
its rights under any of the Loan Documents in good faith and in a commercially reasonable manner.

     (xv) We have not independently examined the physical condition or actual use of the Mortgaged
Properties or the Collateral and express no opinion as to whether the Mortgaged Properties or the
Collateral are in compliance with any laws and regulations relating to the construction, occupation
or use thereof (including, without limitation, zoning laws, subdivision laws, building codes, and
environmental laws and regulations).

     (xvi) With respect to the enforceability and perfection of the security interests through the
filing of UCC-1 Financing Statements, our opinion is limited to the perfection of a security
interest in property of a type where perfection may be had through the filing of a UCC-1 Financing
Statement pursuant to Article 9 of the Delaware UCC.

     (xvii) Whenever our opinion herein is indicated to be based upon the “best of our knowledge,”
or “to our knowledge” or any similar phrases, such phrase is intended to signify that during the
course of our representation of the Borrower, no information has come to the attention of the
attorneys in our office who have worked on this transaction or otherwise regularly perform services
for the Borrower which would give such attorneys actual knowledge contrary to such statement,
provided that no independent investigation was conducted with respect to any such matters except as
specifically set forth at the beginning of this letter.

     Our opinions set forth herein are limited to the date set forth above and to the matters
expressly set forth in this opinion letter, and no opinion is implied or may be inferred beyond the
matters expressly so stated. We assume no obligation to update or supplement this opinion to
reflect any facts or circumstances which may hereafter come to our attention or any changes in laws
which may hereafter occur. This opinion is furnished for the benefit of the Lender and any
transferee or assignee of the Lender in connection with the transactions contemplated by the Credit
Agreement and the other Loan Documents and is not to be relied on, quoted in whole or in part or
otherwise referred to or disclosed to any other person or entity or in any other transaction. Other
than the Lender and any transferee or assignee, we are not hereby assuming any professional
responsibility to any other person.

	 	Re:  	 	Credit Agreement dated June ___, 2008, by and between Legacy Energy,
Inc., a Delaware corporation, and Texas Capital Bank, N.A., a national banking
association (as amended, supplemented, restated or otherwise modified from time
to time, the “Credit Agreement”)

Ladies and Gentlemen:

     We have acted as Louisiana counsel for Legacy Energy, Inc., a Delaware corporation (d/b/a
Legacy Energy, Inc. of Delaware in the State of Louisiana) (the “Borrower”), in connection
with the transactions contemplated in the Credit Agreement. This opinion is furnished pursuant to
Section 3.1(n) of the Credit Agreement, and the Lender is hereby authorized to rely upon this
opinion in connection with the transactions contemplated in the Credit Agreement. For convenience,
each capitalized term used but not defined herein shall have the meaning assigned to such term in
the Credit Agreement, unless expressly provided to the contrary herein.

     In connection with this opinion, we have examined an executed counterpart or a copy of an
executed counterpart of each of the following (collectively, the “Loan Documents”), each of
which is dated of even date herewith:

	 	(a)	 	the Credit Agreement;
	 
	 	(b)	 	the Note; and
	 
	 	(c)	 	the Act of Mortgage, Pledge, Security Agreement and Assignment of Production
from the Borrower in favor of the Lender (the “Act of Mortgage”).

     We have also examined copies of a UCC Financing Statement reflecting the Borrower as the
Debtor and the Lender as the Secured Party to be filed in _____________ Parish, Louisiana (the “Louisiana
Financing Statement”).

     In making such examinations, we have, with your permission, assumed:

VI-i 

 

     (i) the genuineness of all signatures to the Loan Documents other than those of the Borrower;

     (ii) the authenticity of all documents submitted to us as originals and the conformity with
the originals of all documents submitted to us as copies;

     (iii) that the Lender and Borrower are duly organized, legally existing and in good standing
under the respective laws of each of their jurisdictions of organization;

     (iv) that the Lender is authorized and has the power to enter into and perform its obligations
under the Credit Agreement and the other Loan Documents to which it is a party;

     (v) the due authorization, execution and delivery of all Loan Documents by each party thereto;
and

     (vi) that the Borrower has good and marketable title to all Mortgaged Property (as such term
is defined in the Act of Mortgage).

     In addition, with your consent, we have (i) relied on a certificate of good standing issued by
the State of Louisiana on June 17, 2008, that the Borrower is authorized to do business as a
foreign corporation in the State of Louisiana as of such date, (ii) made no additional
investigation after that date, (iii) assumed that the Borrower has “rights in the collateral” and
that “value has been given” both within the meaning of R.S. 10:9-203, and (iv) relied upon the
advise of the Borrower that the Loan Documents have been duly delivered to the Lender.

     Based upon the foregoing and subject to the qualifications set forth herein, we are of the
opinion that:

     1. The Borrower is a foreign corporation authorized to do business in the State
of Louisiana and in good standing under the laws of the State of Louisiana.

     2. The forms of the Act of Mortgage and the Louisiana Financing Statement and
the forms of the descriptions in the Act of Mortgage of the Mortgaged Property
satisfy all applicable laws of the State of Louisiana and are legally sufficient
under the laws of the State of Louisiana to enable the Lender to realize the
practical benefits purported to be afforded by the Act of Mortgage and the Louisiana
Financing Statement. The Act of Mortgage is in proper authentic form under
Louisiana law, although we express no opinion as whether the Act of Mortgage has
been properly executed in authentic form..

     3. The Act of Mortgage creates a perfected mortgage lien in the “Mortgaged
Property” (as defined in the Act of Mortgage) to the extent that such Mortgaged
Property consists of immovable (real) property, and a valid, binding, enforceable,
and perfected security interest in such Mortgaged Property to the extent that such
Mortgaged Property constitutes movable (personal) property, fixtures, as-extracted
collateral or proceeds thereof with respect to which a

VI-ii 

 

security interest can be created under the Uniform Commercial Code of Louisiana
(the “LAUCC”) and perfected by the filing of a financing statement pursuant to the
LAUCC.

     4. The Act of Mortgage and the Louisiana Financing Statement are each in
satisfactory form for filing and recording in the offices described in paragraph
below.

     5. The filing and/or recording, as the case may be, of a counterpart of the Act
of Mortgage in the office of the parish clerk of each parish in the State of
Louisiana in which any portion of the Mortgaged Property (as defined therein) is
located and the filing of a counterpart of the Louisiana Financing Statement in ____________________________________
Parish, Louisiana are the only recordings or filings in the State of Louisiana
necessary to perfect the liens and security interests created by the Act of Mortgage
or to permit the Lender to enforce in the State of Louisiana its rights under the
Act of Mortgage.

     6. No state or local mortgage registration tax stamp tax or other similar fee,
tax or governmental charge (other than statutory filing and recording fees to be
paid upon filing) is required to be paid to the State of Louisiana, or any
subdivisions thereof, in connection with the execution, delivery, filing or
recording of the Act of Mortgage or the Louisiana Financing Statement or the
consummation of the transactions contemplated in those documents.

     The opinions expressed herein are subject to the following qualifications and limitations:

     A. We are licensed to practice law only in the State of Louisiana and other
jurisdictions the laws of which are not applicable to the opinions expressed herein;
accordingly, the foregoing opinions are limited solely to the laws of the State of
Louisiana and applicable United States federal law.

     B. The enforceability of the Loan Documents and the availability of certain
remedial provisions provided for therein may be limited by (i) the effects of
applicable bankruptcy, insolvency, reorganization, moratorium, and similar laws now
or hereinafter in effect relating to or affecting creditors’ rights generally, and
(ii) general equitable principles which may limit the availability of certain
equitable remedies (such as specific performance) in certain circumstances or give
rise to equitable defenses in certain instances. Without further limiting our
opinion as to the validity or form of the underlying instruments, we express no
opinion as to the availability of executory process, which under Louisiana law
depends upon strict technical compliance with all legal requirements for execution
of documents in authentic form, as to which execution we have no direct knowledge.

     C. We express no opinion on the validity, binding effect, or enforceability of
provisions, if any, in the Act of Mortgage that waive or affect demand or notice;
purport to provide remedies inconsistent with applicable law;

VI-iii 

 

create self-help remedies; establish jurisdiction or venue for disputes and
causes of action; waive the right to a jury trial; impose indemnity liability on
others for acts or omissions of any party to the Act of Mortgage; waive the
requirements of good faith and commercial reasonableness; purport to sever
unenforceable provisions to the extent that the enforcement of remaining provisions
would frustrate the fundamental intent of parties thereto; and prohibit or make an
event of default any transfer of any interest in any property. Nonetheless, the
unenforceability of any such provisions will not render any Loan Document invalid as
a whole or interfere with the practical realization of the principal legal benefits
afforded thereby, except for the economic consequences of procedural or other legal
delay.

     This opinion is furnished for the benefit of the Lender and any transferee or assignee of the
Lender in connection with the transactions contemplated by the Credit Agreement and the other Loan
Documents and is not to be quoted in whole or in part or otherwise referred to or disclosed to any
other person or entity or in any other transaction.

Agreement, due to an event or circumstance (other than any action taken by a party or, if
applicable, any Credit Support Provider of such party) occurring after a Transaction is
entered into, it becomes unlawful under any applicable law (including without limitation the
laws of any country in which payment, delivery or compliance is required by either party or
any Credit Support Provider, as the case may be), on any Business Day, or it would be
unlawful if the relevant payment, delivery or compliance were required on that day (in each
case, other than as a result of a breach by the party of

(1) for the Office through which such party (which will be the Affected Party) makes

SECTION 6(e) OF THIS AGREEMENT OR THE OBLIGATION TO PAY ANY AMOUNT REQUIRED PURSUANT TO
SECTION 6(e) OF THIS AGREEMENT; PROVIDED, FURTHER, THIS PART 5(a) SHALL SURVIVE THE
TERMINATION OR EXPIRATION OF THIS AGREEMENT. IF AND TO THE EXTENT ANY PAYMENT REQUIRED TO BE
MADE PURSUANT TO THIS AGREEMENT IS DEEMED TO CONSTITUTE LIQUIDATED DAMAGES, THE PARTIES
ACKNOWLEDGE AND AGREE THAT SUCH DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE AND THAT SUCH
PAYMENT IS INTENDED TO BE A REASONABLE APPROXIMATION OF THE AMOUNT OF SUCH DAMAGES AND NOT A
PENALTY.

7

 

	 	(i)	 	Transactions Entered Into Orally. Should the parties come to an understanding

bound by each Transaction from the time they agree to its terms and acknowledge that
each party will rely thereon in doing business related to the Transaction. Any
Transaction formed and effectuated pursuant to the foregoing shall be considered a
“writing” or “in writing” and to have been “signed” by each party.
	 
	 	(ii)	 	Taping of Transactions. Each party hereby agrees that the other party or its
agents may electronically record all telephone conversations between officers or
employees of the consenting party and the officers or employees of the other party who
quote on, agree to, or otherwise discuss terms of Transactions or potential
Transactions on behalf of the party. Each party may, at each party’s respective
expense, maintain equipment necessary to record Transactions on audiotapes and/or
digital recording media (“Transaction Tapes”) and retain Transaction Tapes and the
electronic evidence of Transactions on such Transaction Tapes in such manner and for so
long as each party deems necessary in its sole respective discretion, but is not
obligated to do so; provided that NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR
ANY MALFUNCTION OF SUCH EQUIPMENT OR THE OPERATION THEREOF IN RESPECT OF ANY
TRANSACTION WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING, WITHOUT
LIMITATION, THE SOLE, JOINT, CONCURRENT, CONTRIBUTORY, AND/OR COMPARATIVE NEGLIGENCE
(WHETHER GROSS OR SIMPLE, OR ACTIVE OR PASSIVE), STRICT LIABILITY, OR OTHER FAULT OF
ANY PARTY. No Transaction shall be invalidated should a Transaction Tape be erased for
any reason or a malfunction occur in equipment utilized for recording Transactions or
retaining Transaction Tapes or the operation thereof.
	 
	 	(iii)	 	Waiver of Statute of Frauds. THE PARTIES HEREBY WAIVE ALL PROVISIONS OF ANY
APPLICABLE STATUTE OF FRAUDS WITH RESPECT TO ANY TRANSACTIONS SUBJECT TO THIS
AGREEMENT; PROVIDED, HOWEVER, AMENDMENTS TO THE TERMS AND PROVISIONS OF THIS AGREEMENT
MUST BE IN WRITING AND SIGNED BY THE PARTIES. The parties agree not to contest or
assert a defense to the validity or enforceability of Transactions entered into orally
under laws relating to whether certain agreements are to be in writing or signed by the
party to be thereby bound.
	 
	 	(iv)	 	Confirmation of a Transaction.

	 	(1)	 	With respect to each Transaction entered into pursuant to this
Agreement, Party A will promptly send a Confirmation to Party B by any
reasonable means, including, without limitation, by facsimile, hand delivery,
courier, or certified United States mail (return receipt requested). Failure
by Party A to send, or Party B to return, a Confirmation shall not invalidate
any Transaction. Party A adopts its confirming letterhead, or the like, as its
signature on any Confirmation as its identification and authentication.
	 
	 	(2)	 	If Party A’s Confirmation is materially different from Party
B’s understanding of the terms of a Transaction, Party B shall notify Party A
of any such material differences in writing by the Confirm Deadline. “Confirm
Deadline” shall mean 5:00 p.m. in Party B’s time zone on the fifth New York
Business Day following the New York Business Day a Confirmation is received by
Party B; provided, if the Confirmation is received after 5:00 p.m. in Party B’s
time zone, it shall be deemed received at the opening of the next New York
Business Day. “New York Business Day” shall mean any day except for a
Saturday, Sunday or a day on which the Federal Reserve Bank of New York is
closed.
	 
	 	(3)	 	The failure of Party B to so notify Party A of any such
material differences in writing by the Confirm Deadline constitutes Party B’s
acceptance of the description of the terms of the Transaction in Party A’s
Confirmation. If Party B has timely objected in writing to the terms of Party
A’s Confirmation, such Transaction remains valid and the parties remain legally

8

 

	 	 	 	bound thereby; however, both parties shall in good faith attempt to resolve
such differences. Once such material differences are resolved, Party A may
transmit a written Confirmation to Party B, and such written Confirmation
shall be accepted (or disputed) pursuant to the provisions of Part 5(b)(iv).
The provisions of Part 5(b)(iv) may be repeated as many times as necessary
to produce a written Confirmation that is accepted or deemed accepted by the
receiving party.

	 	(4)	 	Notwithstanding the provisions of Section 12(a)(iii) of the
Agreement, a written Confirmation and any other writing related to or in
response to a written Confirmation shall be deemed delivered to the receiving
party (i) when actually received by the receiving party or (ii) with respect to
a written Confirmation and other writing delivered by facsimile, when the
sending party’s facsimile machine indicates by an electronic or written
facsimile log that the receiving party’s facsimile machine received such
written Confirmation.
	 
	 	(5)	 	Party A shall not be required to maintain or retain a
paper-based version of the written Confirmation delivered to Party B. In
addition to a paper-based version of the written Confirmation delivered to
Party B, the following shall constitute a “written Confirmation” for all
purposes of this Agreement: (i) an electronic image of a paper-based version of
the written Confirmation, and (ii) data in Party A’s computer system.
	 
	 	(6)	 	In the absence of a written Confirmation that the parties have
signed or deemed to have accepted, any evidence may be used to establish the
terms of a Transaction, including, without limitation, a Transaction Tape, oral
testimony, data in a computer system, trade tickets, and/or notes. If a
written Confirmation exists which the parties have executed or deemed to have
accepted, in the event of conflict between the terms of the written
Confirmation and any other evidence of the terms of a Transaction (including,
without limitation, a Transaction Tape, oral testimony, data in a computer
system, trade tickets, and/or notes), the terms of the written Confirmation
shall control to the extent of any such conflict.

	 	(v)	 	Confirmations Do Not Amend Certain Terms. Confirmations shall not amend the
terms of this Agreement unless a Confirmation is in writing and signed by both parties.

	(c)	 	Applicable Rate. The definition of “Applicable Rate” set forth in Section 14 is hereby
amended by adding to the end of Section (b) of the definition after the word “Rate” the
following provision: “; provided, however, that if the payee is a Defaulting
Party for purposes of Section 6(e), then the rate shall be the Non-default Rate.”
	 
	(d)	 	Limitation of Rate. Notwithstanding any provision to the contrary contained in this
Agreement, in no event shall the Default Rate, Non-default Rate, or Termination Rate exceed
the maximum non-usurious interest rate, if any, that at any time or from time to time may be
contracted for, taken, reserved, charged, or received on the subject indebtedness under the
law applicable to such party.
	 
	(e)	 	Set-off. Without affecting or prejudicing the provisions of this Agreement requiring the
calculation and payment of certain net payment amounts on Scheduled Payment Dates, all
payments will be made without Set-off or counterclaim; provided, however, that upon the
designation or deemed designation of an Early Termination Date, in addition to and not in
limitation of any other right or remedy (including any right to Set-off, counterclaim, or
otherwise withhold payment) under applicable law or this Agreement, the Non-defaulting Party
or the non-Affected Party (in either case, “X”) may, at its option and in its discretion,
Set-off, against any amounts owed to the Defaulting Party or Affected Party (in either case,
“Y”) in Dollars or any other currency by X or any Affiliate of X under this Agreement or
otherwise, any amounts owed in Dollars or any other currency by Y to X or any Affiliate of X
under this Agreement or otherwise. The obligations of Y and X under this Agreement in respect
of such amounts shall be deemed satisfied and discharged to the extent of any such Set-off.
For this purpose, the amounts subject to the Set-off may be

9

 

	 	 	converted at the applicable prevailing exchange rate into the Termination Currency by X. If
the amount of an obligation has not been ascertained, X may, in good faith, estimate that
obligation and Set-off in respect of the estimate, subject to X or Y, as the case may be,
accounting to the other party when the obligation is ascertained. X will give Y notice of
any Set-off effected under this section provided that failure to give such notice shall not
affect the validity of the Set-off. Nothing in this paragraph shall be deemed to create a
charge or other security interest. The rights provided by this paragraph are in addition to
and not in limitation of any other right or remedy (including any right to Set-off,
counterclaim, or otherwise withhold payment) to which a party may be entitled (whether by
operation of law, contract or otherwise).

	(f)	 	Definitions and Inconsistency. This Agreement, each Confirmation, and each Transaction are
subject to the 2006 ISDA Definitions (the “Swap Definitions”), the 2005 ISDA Commodity
Definitions, (the “Commodity Definitions”) each as published by the International Swaps and
Derivatives Association, Inc. (collectively the “ISDA Definitions”). The ISDA Definitions are
incorporated by reference herein, and made part of, this Agreement and each Confirmation as if
set forth in full in this Agreement and such Confirmations. Unless otherwise specified in a
Confirmation, any capitalized terms used herein and not otherwise defined herein shall have
the respective meanings ascribed to them in the Swap Definitions, and the Commodity
Definitions (except that references to “Swap Transactions” in the definitions will be deemed
to be references to “Transactions”). In the event of any inconsistency between the provisions
of the Swap Definitions and the Commodity Definitions, the Commodity Definitions will prevail.
In the event of any inconsistency between the provisions of this Agreement and the ISDA
Definitions, this Agreement will prevail. In the event of any inconsistency between the
provisions of the Credit Support Documents, if any, and the ISDA Definitions, the Credit
Support Documents will prevail. Subject to Section 1(b) of this Agreement, in the event of
any inconsistency between the provisions of any Confirmation and this Agreement or the ISDA
Definitions, the Confirmation will prevail for the purpose of the relevant Transaction;
provided however, a Confirmation may not amend or conflict with any provisions of this
Agreement regarding Events of Default, or Termination Events.
	 
	(g)	 	Change of Account. Section 2(b) is hereby amended by adding the following at the end thereof:
	 
	 	 	“and provided that, unless the other party consents (which consent shall not be unreasonably
withheld, conditioned, or delayed), such new account shall be in the same tax jurisdiction
as the original account.”
	 
	(h)	 	Deduction or Withholding for Tax. Section 2(d)(i)(4) of this Agreement is amended by the
addition of
	 
	 	 	a new sub-paragraph (C) as follows:
	 
	 	 	“(C) Y refusing to supply any form or document under 4(a)(iii) on grounds of material
prejudice to its legal or commercial position.”
	 
	 	 	Section 5(b)(ii) will be amended by the addition of “or (C)” after the words “or (B)” at the
end of the last line.
	 
	(i)	 	Agreements — Notices. Section 4(d) of this Agreement is hereby deleted in its entirety and
replaced by the following:
	 
	 	 	“(d) Notice. It will give notice of any failure of a representation made by it under
Section 3(f) to be accurate and true promptly upon learning of such failure.
	 
	(j)	 	Termination Payments by Non-Defaulting Party. Notwithstanding the provisions of Sections
6(e) and 6(d) of the Agreement, if there is a Defaulting Party, the obligations of the
Non-defaulting Party to pay to the Defaulting Party any amount under Section 6(e) shall not
arise until, and shall be subject to the conditions precedent that, the Non-defaulting Party
shall have received confirmation satisfactory to it in its sole discretion that (A) all
Transactions are terminated in accordance with Section 6(c), and (B) all obligations
(contingent or absolute, matured or unmatured) of the Defaulting Party and any Affiliate of
the Defaulting Party and any Affiliate of the Defaulting Party to make any payment to the
Non-defaulting Party

10

 

	 	 	or any Affiliate of the Non-defaulting Party shall have been fully and finally performed,
and (C) if the Defaulting Party is subject to the jurisdiction of a bankruptcy court, an
order of such bankruptcy court (in form reasonably acceptable to the Non-defaulting Party)
shall be final and non-appealable and shall approve such payment by the Non-defaulting
Party; and provided, further, that if under the foregoing provisions it is
determined that the Non-defaulting Party is to make a payment to the Defaulting Party, there
shall be deducted from the amount of such payment all amounts which the Defaulting Party may
be obligated to pay under Section 11.

	(k)	 	Transfer. Section 7 is hereby amended to read as follows:
	 
	 	 	“Subject to the last sentence of Section 6(b)(ii), neither this Agreement nor any interest
or obligation in or under this Agreement may be transferred (whether by way of security or
otherwise) by either party without the prior written consent of the other party and any
purported transfer without such consent will be void.”
	 
	(l)	 	Waiver of Right to Trial by Jury. Each of the parties hereby irrevocably waives any and all
right to a trial by jury with respect to any legal proceeding arising out of or relating to
this Agreement or any Transaction.
	 
	(m)	 	Additional Representations. Section 3 of the Agreement is hereby amended by adding at the
end thereof the following subsections (g) through (k):
