TERM NOTE

$309,681.87 Midland, Texas September 1, 2009

1. For value received, ESCONDE RESOURCES LP, a Texas limited partnership, (the “Maker”), promises
to pay to the order of AMERICAN STATE BANK, a Texas banking association (the “Bank”), at its
offices at 620 N. Grant Avenue, Odessa, Texas 79761, in lawful money of the United States of
America, the sum of THREE HUNDRED NINE THOUSAND SIX HUNDRED EIGHTY-ONE AND EIGHTY-SEVEN/100 DOLLARS
($309,681.87), together with interest on the principal amount from time to time outstanding
hereunder, from the date of disbursement of such principal until maturity, at a variable rate of
interest per annum (the “Variable Rate") equal to the “American State Bank Base Rate”, as defined
below, plus two percentage points (2.0%), but shall never be less than six percentage points
(6.00%), and shall in no event to exceed the “Highest Lawful Rate,” as defined below, with
adjustments to the Variable Rate to be made on the same date as the effective date of any change in
the American State Bank Base Rate and adjustments due to changes in the Highest Lawful Rate to be
made on the effective date of any change in the Highest Lawful Rate.

2. This Note is executed pursuant to the terms of that certain Loan Agreement, dated as of
September 1, 2009, by and among Maker, as Borrower; Esconde Energy LLC, as Guarantor; and Bank, as
Lender (the “Loan Agreement”). This Note incorporates by reference the terms of the Loan
Agreement. In the event of a conflict between the terms of this Note and the terms of the Loan
Agreement, the terms of the Loan Agreement shall be deemed to be controlling.

3. Notwithstanding the foregoing, if at any time the Variable Rate exceeds the Highest Lawful Rate,
the rate of interest to accrue on this Note shall be limited to the Highest Lawful Rate, but any
subsequent reductions in such Variable Rate shall not reduce the rate of interest to accrue on this
Note below the Highest Lawful Rate until the total amount of interest accrued on this Note equals
the amount of interest which would have accrued if the Variable Rate had at all times been in
effect.

4. If at maturity or final payment of this Note the total amount of interest paid or accrued under
the foregoing provisions is less than the total amount of interest which would have accrued if the
Variable Rate had at all times been in effect, then Makers agree to pay to Bank, to the extent
permitted by law, an amount equal to the difference between (a) the lesser of (i) the amount of
interest which would have accrued on this Note if the Highest Lawful Rate had at all times been in
effect, or (ii) the amount of interest which would have accrued if the Variable Rate had at all
times been in effect, and (b) the amount of interest accrued in accordance with the other
provisions of this Note.

5. The term “American State Bank Base Rate” shall mean the rate announced by Bank as its base
lending rate as of the beginning of each Business Day, as hereinafter defined, (and for holidays or
weekends the Base Rate shall be the American State Bank Base Rate as of the close of business on
the most recent Business Day immediately preceding such weekend or holiday) before all sums payable
hereunder have been paid in full. Without notice to the Makers or any other person, the Base Rate
may change from time to time pursuant to the preceding sentence. The Base Rate is a reference rate
and does not necessarily represent the lowest or best rate actually charged to any customer. Bank
may make commercial loans or other loans at rates of interest at, above or below the Base Rate.
Business Day shall mean a day other than a Saturday, Sunday, or legal holiday for commercial banks
under the laws of the State of Texas.

6. The term “Highest Lawful Rate” shall mean the maximum nonusurious interest rate, if any, that at
any time or from time to time may be contracted for, taken, reserved, charged, collected or
received by the Bank in connection with this Note under laws applicable to the Bank which are
presently in effect or, to the extent allowed by law, under applicable laws which may hereafter be
in effect and which allow a higher maximum nonusurious interest rate than applicable laws now
allow.

7. The principal balance of this Note shall be due and payable on or before December 15, 2009.

8. Interest, computed on the unpaid principal balance of this Note shall be due and payable as it
accrues monthly, commencing on September 15, 2009, and thereafter on the fifteenth day of each and
every succeeding month during the term hereof, until maturity, December 15, 2009, when the entire
amount of this Note, principal and accrued, unpaid interest, shall be due and payable.

9. All past due principal and interest on this Note shall bear interest from the maturity thereof
until paid, at the Highest Lawful Rate. Interest on this Note shall be computed on a 365/360 simple
interest basis; that is, by applying the ratio of the annual interest over a year of 360 days,
times the outstanding principal balance, times the actual number of days the principal is
outstanding, unless such calculation would result in a usurious rate, in which case interest shall
be calculated on a per diem basis of 360 days.

10. If an Event of Default should occur under the Loan Agreement, thereupon, following any
applicable notice and cure provisions, at the option of Bank, the principal balance and accrued
interest of the Note, and any and all other indebtedness of Makers to Bank shall become and be due
and payable forthwith without demand, notice of default, notice of acceleration, notice of intent
to accelerate the maturity hereof, notice of nonpayment, presentment, protest or notice of
dishonor, all of which are hereby expressly waived by Makers and each other liable party. Bank may
waive any default without waiving any prior or subsequent default.

11. If a payment is ten (10) days or more late, Makers will be charged five percent (5%) of the
regularly scheduled payment or $100.00, whichever is less.

12. To the extent not prohibited by applicable law, Makers will pay all reasonable costs and
expenses and reimburse Bank for any and all expenditures of every character incurred or expended
from time to time, regardless of whether an Event of Default shall have occurred, in connection
with (a) Bank’s evaluating, monitoring, administering and protecting the Mortgaged Property, as
hereinafter defined, and (b) Bank’s creating, perfecting or realizing upon Bank’s security interest
in and liens on the Mortgaged Property, and all reasonable costs and expenses relating to Bank’s
exercising any of its rights and remedies under this or any other instrument now or hereafter
securing the Indebtedness or at law, including, without limitation, all filing fees, taxes,
brokerage fees and commissions, title review and abstract fees, Uniform Commercial Code search
fees, other fees and expenses incident to title searches, reports and security interests, escrow
fees, attorneys’ fees, legal expenses, court costs, fees and expenses incurred in connection with
any complete or partial liquidation of the Mortgaged Property, and all fees and expenses for any
professional services relating to the Mortgaged Property or any operations conducted in connection
with it; provided, however, that no right or option granted by Makers or Bank or otherwise arising
pursuant to any provision of this or any other instrument shall be deemed to impose or admit a duty
on the Bank to supervise, monitor or control any aspect of the character or condition of the
Mortgaged Property or any operations conducted in connection with it for the benefit of Makers or
any other person or entity other than the Bank.

13. If this Note is not paid at maturity whether by acceleration or otherwise and is placed in the
hands of an attorney for collection, or suit is filed hereon, or proceedings are had in probate,
bankruptcy, receivership, reorganization, arrangement or other legal proceedings for collection
hereof, Makers and each other liable party agrees to pay Bank their collection costs, including a
reasonable amount for attorney’s fees, but in no event to exceed the maximum amount permitted by
law. Makers and each other liable party is and shall be directly and primarily, jointly and
severally, liable for the payment of all sums called for hereunder, and Makers and each other
liable party hereby expressly waives bringing of suit and diligence in taking any action to collect
any sums owing hereon and in the handling of any security, and Makers and each other liable party
hereby consents to and agrees to remain liable hereon regardless of any renewals, extensions for
any period or rearrangements hereof, or partial prepayments hereon, or any release or substitution
of security hereof, in whole or in part, with or without notice, from time to time, before or after
maturity.

14. It is the intent of the Makers and Bank in the execution and performance of this note to
contract in strict compliance with the usury laws of the State of Texas and the United States of
America from time to time in effect. For purposes hereof, “interest” shall include the aggregate
of all charges which constitute interest under such laws that are contracted for, reserved, taken,
charged or received under this note. In furtherance thereof, the Bank and the Makers stipulate and
agree that none of the terms and provisions contained in this note, shall ever be construed to
create a contract to pay for the use, forbearance or detention of money with interest at a rate in
excess of the Highest Lawful Rate. In the event the Bank or any other holder of the note ever
charges or contracts for any amount in excess of lawful interest, the documents or instruments
constituting such charge or contract shall be ipso facto modified without any further action by any
party so that no amount in excess of lawful interest shall be charged or contracted for. If the
Bank or any other holder of the note ever receives, collects or applies as interest any amount in
excess of lawful interest, such amount which would be excessive interest shall be applied to the
reduction of the unpaid principal balance of the note, and, if upon such application the principal
balance of the note is paid in full, any remaining excess shall be forthwith paid to the Makers.
In determining whether or not the interest paid or payable under any specific contingency exceeds
the Highest Lawful Rate, the Makers and the Bank shall, to the maximum extent permitted under
applicable law, (a) treat all advances as but a single extension of credit (and the Makers and the
Bank agree that such is the case and that provision herein for multiple advances is for convenience
only), (b) characterize any nonprincipal payment as an expense, fee or premium rather than as
interest, (c) exclude voluntary prepayments and the effects thereof, and (d) “spread” the total
amount of interest throughout the entire contemplated term of the note. The provisions of this
paragraph shall control over all other provisions of the note or other documents executed in
connection with this note which may be in apparent conflict herewith.

15. Except as otherwise provided in the Loan Documents, all payments and prepayments on this Note,
including proceeds from the exercise of any Rights of the Bank under the Loan Documents, shall be
applied to this Note in the following order: (i) first, to the accrued interest on this Note being
paid or prepaid; (ii) to the principal of this Note being paid or prepaid, with the amounts so
prepaid to be applied upon installments of most remote maturity; (iii) to any remaining obligation
of Borrower under the Loan Agreement, and (iv) last, to reasonable expenses for which the Bank
shall not have been reimbursed under the Loan Documents and then to all amounts to which the Bank
is entitled to indemnification under the Loan Documents.

16. Makers reserve the option of prepaying the principal of this Note, in whole or in part, at any
time after the date hereof without penalty. At the option of Bank, it may demand (at any time at
or after prepayment) all accrued and unpaid interest with respect to the principal amount prepaid
through the date of prepayment. All amounts of principal so prepaid and received by the owner and
holder of this Note shall be applied to the last maturing installments of this Note in their
inverse order of maturity.

17. Unless otherwise specified below, this Note shall be construed under and governed by the laws
of the State of Texas (including applicable federal law), but in any event TEX. FIN. CODE ANN.
SECTION 346.001 et. seq. (which regulates certain revolving loan accounts and revolving tripartite
accounts) shall not apply to the loan evidenced by this Note.

18. Unless changed in accordance with the law, the applicable rate ceiling under Texas law shall be
the indicated (weekly) rate ceiling from time to time in effect as provided in TEX. FIN. CODE ANN.
Section 303.001 et seq., as amended.

19. Makers warrant and represent to the Bank, and to all other holders of this note that all loans
evidenced by this Note are and will be for business, commercial, investment or other similar
purposes and not primarily for personal, family, household or agricultural use, as such terms are
used in TEX. REV. CIV. STAT. ANN. ART. 5069-1D. 201, as amended.

20. This Note is secured by the pledge of the following Collateral:

	 	a.	 	all present and future interests now owned or hereafter acquired by the Maker
in those oil, gas, and mineral properties identified in Deeds of Trust, by and between
Makers and the Lender, together with all proceeds of production therefrom;

	 	b.	 	all present and future increases, profits, combinations, reclassifications,
improvements and products of, accessions, attachments, and other additions to, and
substitutes and replacements for, any of the Collateral;

	 	c.	 	all cash and noncash proceeds and other Rights arising from or by virtue of, or
from the voluntary or involuntary sale, lease or other disposition of, or collections
with respect to, or insurance proceeds payable with respect to, or proceeds payable by
virtue of warranty or other claims against manufacturers of, or claims against any
other persons with respect to, any of the Collateral;

	 	d.	 	all present and future security for the payment to Borrower for any of the
Collateral;

	 	e.	 	all goods which gave or will give rise to any of the Collateral or are
evidenced, identified or represented therein or thereby; and

	 	f.	 	all certificates of title, manufacturer’s statements of origin, or other
documents, accounts and chattel paper arising from or related to any of the Collateral.

The Collateral is covered and governed by Deeds of Trust, Security Agreements, and Financing
Statements, or amendments thereto, of even date herewith, covering oil and gas properties located
in Borden, Garza, and Scurry Counties, in the State of Texas. The Maker’s performance under this
Note is further secured by that certain Guaranty Agreement, also of even date herewith, executed by
Esconde Energy LLC. Failure to describe all or part of the security shall not be considered as a
waiver of such security.

21. Bank reserves the right, exercisable in Bank’s sole discretion and without notice to Makers or
any other person, to sell participations, to assign its interest or both, in all or any part of the
Note or the debt evidenced by the Note.

22. By execution of this Note, Makers acknowledge the receipt of the following notices from Bank:

chattel paper, securities, accounts, general intangibles, fixtures, real property or other assets
(the Mortgaged Property, Collateral and the proceeds of the Collateral and payments in lieu of
Production, collectively, the AProperty@).

CERTAIN REPRESENTATIONS, WARRANTIES,

AND COVENANTS OF GRANTOR

Section 2.1 Representations and Warranties. With knowledge that Beneficiary is
relying on the representations and warranties made herein without independent investigation,
Grantor hereby covenants, agrees, represents, and warrants to Beneficiary that:

(a) Authority. The Subject Leases are valid and subsisting and are in
full force and effect, and Grantor has authority to execute this Deed of Trust, to grant,
bargain, sell, mortgage, assign, transfer, and convey the Mortgaged Property to the Trustee
pursuant to this Deed of Trust, and to make the covenants, representations, warranties, and
assignments contained in this Deed of Trust.

(b) Title. Grantor (i) has good and indefeasible title to, (ii) is lawful
owner and holder of, and (iii) is possessed of the Mortgaged Property free and clear of any
and all liens except Permitted Liens.

(c) Interests. With respect to each Mortgaged Property, the ownership of
Grantor in such Mortgaged Property does and will, (i) with respect to each well described in
Exhibit “A” hereto in connection with such Mortgaged Property, (A) entitle Grantor to
receive (subject to the terms and provisions of this Mortgage) a decimal share of the
Production produced from, or allocated to, such well equal to not less than the decimal
share set forth in Exhibit “A” in connection with such well opposite the words ANet
Revenue Interest@ (or words of similar import), (B) cause Grantor to be obligated to
bear a decimal share of the cost of exploration, development and operation of such well not
greater than the decimal share set forth in Exhibit “A” in connection with such well
opposite the words AWorking Interest@ (or words of similar import) and (ii) if
such Mortgage Property is shown in Exhibit “A” to be subject to a unit or units, with
respect to each such unit, (A) entitle Grantor to receive (subject to the terms and
provisions of this Mortgage) a decimal share of Production produced from, or allocated to,
such unit equal to not less than the decimal share set forth in Exhibit “A” in connection
with such Mortgaged Property opposite the words AUnit Net Revenue Interest@ or
words of similar import (and if such Mortgaged Property is subject to more than one unit,
words identifying such interest with such unit), and (B) obligate Grantor to bear a decimal
share of the cost of exploration, development and operation of such unit not greater than
the decimal share set forth in Exhibit “A” in connection with such Mortgaged Property
opposite the words AUnit Working Interest@ or words of similar import (and if
such Mortgaged Property is subject to more than one unit, words identifying such interest
with such unit); such shares of Production which Grantor is entitled to receive, and shares
of expenses which Grantor is obligated to bear, are not and will not be subject to change
(other than changes which arise pursuant to non-consent provisions of operating agreements
described in Exhibit “A” in connection with such Mortgaged Properties, respectively, in
connection with operations hereafter proposed) except, and only to the extent that, such
changes are reflected in Exhibit “A”. There is not and will not be any unexpired financing
statement covering any part of the Property on file in any public office naming any party
other than Lender as secured party. The execution, delivery and performance of this
Mortgage and the creation of the liens hereunder do not violate any provision or constitute
a default under any operating agreement or other instrument which affects any Mortgaged
Property or to which Grantor is a party.

(d) Advance Payment Contract. Grantor is not a party to any Advance Payment
Contract affecting or relating to any of the Subject Interests not heretofore disclosed to
Beneficiary in writing.

(e) Environmental.

(i) Current Status. The Property and Grantor and, to the best knowledge
of Grantor, any property adjoining the Property are not in violation of or subject to
any existing, pending or, to the best knowledge of Grantor, threatened investigation
or inquiry by any governmental authority or to any remedial obligations under any
AEnvironmental Laws@ (as hereinafter defined), and this representation
will continue to be true and correct following disclosure to the applicable
governmental authorities of all relevant facts, conditions, and circumstances, if
any, pertaining to the Property and Grantor. Grantor undertook, at the time of
acquisition of the Property, all appropriate inquiry into the previous ownership and
uses of the Property consistent with good commercial or customary practice to
determine if the Property is in violation of any Environmental Laws. Grantor has
taken all steps necessary to determine and has determined that no Hazardous Materials
have been disposed of or otherwise released on or to the Property except in
accordance with Environmental Laws. The use which Grantor makes and intends to make
of the Property will not result in the disposal or other release of any Hazardous
Material on or to the Property except in accordance with Environmental Laws. In the
event any Environmental Law is amended so as to broaden the meaning of any term
defined thereby, such broader meaning shall apply subsequent to the effective date of
such amendment and provided further, to the extent that the applicable laws and
regulations promulgated by the United States of America, the State of Texas, or other
applicable jurisdiction establish a meaning for any term defined thereby which is
broader than that specified in any Environmental Law, such broader meaning shall
apply. The AAssociated Property@ (as hereinafter defined) is not in
violation of any Environmental Law for which Grantor or its predecessors in interest
in the Property would be responsible. As used in this Mortgage, the term
AAssociated Property@ means any and all real and/or personal property
interests in and to (and/or carved out of) the Lands which are described or referred
to as Exhibit “A” hereto, or which are otherwise described in any of the oil, gas
and/or mineral leases or other instruments described or referred to in such Exhibit
“A”.

(ii) Future Performance. Grantor will not cause or permit the
Property, the Associated Property or Grantor to be in violation of, or do anything or
permit anything to be done which will subject the Property or the Associated Property
to any remedial obligations under any Environmental Laws, including without
limitation CERCLA, RCRA, the Toxic Substance Control Act, assuming disclosure to the
applicable governmental authorities of all relevant facts, conditions and
circumstances, if any, pertaining to the Property or Associated Property and Grantor
will promptly notify Beneficiary in writing of the presence of any Hazardous Material
on the Property or Associated Property and of any existing, pending or, to the best
knowledge of Grantor, threatened investigation or inquiry by any governmental
authority in connection with any Environmental Laws. Grantor will take all steps
necessary to determine that no Hazardous Materials have been disposed of or otherwise
released on or to the Property or Associated Property except in accordance with
Environmental Laws. Grantor will not cause or permit the disposal or other release
of any Hazardous Materials on or to the Property, or the Associated Property or any
property adjoining the Property except in accordance with Environmental Laws and
covenants and agrees to keep or cause the Property and the Associated Property to be
kept free of any Hazardous Materials and to remove the same (or if removal is
prohibited by law, to take whatever action is required by law) promptly upon
discovery at its sole expense. Without limitation of the Beneficiary’s rights to
declare an event of default hereunder and to exercise all remedies available by
reason thereof, in the event Grantor fails to comply with or perform any of the
foregoing covenants and obligations, the Beneficiary may (without any obligation,
express or implied) remove any Hazardous Materials from the Property or the
Associated Property (or if removal is prohibited by law, take whatever action is
required by law) and the cost of the removal or such other action shall be a demand
obligation owing by Grantor to the Beneficiary pursuant to this Mortgage. Grantor
grants to Beneficiary and its agents, employees, contractors and consultants access
to the Property and the Associated Property and the license (which is coupled with an
interest and irrevocable while this Mortgage is in effect) to remove the Hazardous
Materials (or if removal is prohibited by law, to take whatever action is required by
law) and agrees to indemnify and hold Beneficiary harmless from all costs and
expenses involved therewith. Upon Beneficiary’s reasonable request, at any time and
from time to time during the existence of this Mortgage, Grantor will provide at
Grantor’s sole expense an inspection or audit of the Property and the Associated
Property from an engineering or consulting firm approved by Beneficiary, indicating
the presence or absence of Hazardous Materials on the Property. If Grantor fails to
provide same after ten (10) days’ notice, Beneficiary may order same, and Grantor
grants to Beneficiary and its employees, agents, contractors and consultants access
to the Property and the Associated Property and a license (which is coupled with an
interest and irrevocable while this Mortgage is in effect) to perform such
inspections and tests. The cost of such inspections and tests shall be a demand
obligation owing by Grantor to Beneficiary pursuant to this Mortgage. The
Beneficiary’s rights under this paragraph are for the sole purpose of protecting the
Beneficiary’s security for the repayment of the secured indebtedness and shall not
under any circumstance be construed as granting the right to participate or
constitute participation in the management of the Property or the business conducted
thereon.

(f) Compliance with Applicable Laws. Grantor represents that, to the best of
its knowledge, Grantor is currently in compliance with all applicable laws, ordinances,
rules and regulations governing Grantor=s ownership, use and operation of the
Mortgaged Property.

(g) Rents, Royalties and Taxes. All rents and royalties due and payable under
the Subject Leases have been paid or otherwise accounted for and all Hydrocarbon severance
and production Taxes, windfall profit Taxes, and all property Taxes payable by Grantor with
respect to the Mortgaged Property have been paid.

(h) Condition of Personal or Movable Property. The equipment, inventory,
improvements, fixtures, goods and other tangible personal/movable property forming a part of
the Property are and will remain in good repair and condition and are and will be adequate
for the normal operation of the Property in accordance with prudent industry standards; all
of such Property is, and will remain, located on the Mortgaged Property, except for that
portion thereof which is or shall be located elsewhere (including that usually located on
the Mortgaged Properties but temporarily located elsewhere) in the course of the normal
operation of the Property.

Section 2.2 Covenants of Grantor. Grantor, for Grantor and Grantor’s successors,
covenants and agrees, unless otherwise specifically permitted or allowed in the Loan Agreement, to:

such legal proceedings, including, but not limited to, the employment of counsel acceptable
to Beneficiary, the prosecution or defense of litigation and the release or discharge of all
adverse claims, and Trustee and Beneficiary, or either of them (whether or not named as
parties to legal proceedings with respect thereto), are hereby authorized and empowered to
take such additional steps as in their judgment and discretion may be necessary or proper
for the defense of any such legal proceedings, including, but not limited to, the

his duty, upon such request of Beneficiary, and to the extent permitted by applicable Law,
to sell all or any part of the Mortgaged Property at one or more sales, as an entirety or in
parcels, at such place or places and otherwise in such manner and upon such notice as may be
required by applicable Law, or in the absence of any such requirement, as Trustee and/or
Beneficiary may deem appropriate, and to make conveyance to the purchaser or purchasers
thereof. Any sale of any part of the Mortgaged Property shall be made to the highest bidder
or bidders for cash, at the courthouse door of, or at such other place as may be required or
permitted by applicable Law in, the county (or judicial district) wherein the Land included
within the Mortgaged Property to be sold is situated; provided that if the Land is situated
in more than one county (or judicial district), such sale of the Mortgaged Property, or any
part thereof, may be made in any county (or judicial district) wherein any part of the Land

applicable Law in effect at the time of such sale; and nothing herein shall be deemed to
require Beneficiary or Trustee to do, and Beneficiary and Trustee shall not be required to
do, any act other than as required by applicable Law in effect at the time of such sale.

Trustee shall make to the purchaser or purchasers thereunder good and sufficient deeds and
assignments, in the name of Grantor, conveying the Mortgaged Property, or part thereof, so
sold to the purchaser or purchasers with general warranty of title (subject to Permitted
Liens) by Grantor. Sale of a part of the Mortgaged Property shall not exhaust the power of
sale, but sales may be made from time to time until the Obligation is paid and performed in
full. It shall not be necessary to have present or to exhibit at any such sale any of the
Collateral. In addition to the Rights and powers of sale granted under the preceding
provisions of this Subsection 3.2(c), if default is made in the payment of any installment
of the Obligation, Beneficiary, at its option, at once or at any time thereafter while any
matured installment remains unpaid, without declaring the entire Obligation to be due and
payable may orally or in writing direct Trustee to enforce this trust and to sell the
Mortgaged Property subject to such unmatured Obligation and the Liens securing its payment,
in the same manner, on the same terms, at the same place and time, and after having given
notice in the same manner, all as provided in the preceding provisions of this Subsection
3.2(c). After such sale, Trustee shall make due conveyance to the purchaser or purchasers.
Sales made without maturing the Obligation may be made hereunder whenever there is a default
in the payment of any installment of the Obligation without exhausting the power of sale
granted hereby, and without affecting in any way the power of sale granted under this
Subsection 3.2(c) on the unmatured balance of the Obligation (except as to any proceeds of
any sale which Beneficiary may apply as a prepayment on the Obligation) or the Liens
securing payment of the Obligation. It is intended by each of the foregoing provisions of
this Subsection 3.2(c) that Trustee may, after any request or direction by Beneficiary,
sell, not only the Subject Interests included within, but also, all other items constituting
a part of, the Mortgaged Property, or any part thereof, along with the Land, or any part
thereof, included within the Mortgaged Property all as a unit and as a part of a single
sale, or may sell any part of the Mortgaged Property separately from the remainder of the
Mortgaged Property. It is agreed that, in any deed or assignment given by Trustee, any and
all statements of fact or other recitals therein made as to the identity of Beneficiary, or
as to the occurrence or existence of any Default, or as to the acceleration of the maturity
of the Obligation, or as to the request to sell, notice of sale, time, place, terms and
manner of sale, and the receipt, distribution and application of the money realized
therefrom, or as to the due and proper appointment of a substitute trustee, and, without
being limited by the foregoing, as to any other act or thing having been duly done by
Beneficiary or by Trustee, shall be taken by all courts of law and equity as prima
facie evidence that the said statements or recitals state facts and are without
further question to be so accepted, and Grantor does hereby ratify and confirm any and all
acts that Trustee may lawfully do in the premises by virtue hereof. In the event of the
resignation (such resignation being hereby authorized for any reason) or death of Trustee,
or his removal from his county of residence stated on the first page hereof, or his failure,
refusal or inability, for any reason, to make any such sale or to perform any of the trusts
herein declared, or, at the option of Beneficiary, without cause, Beneficiary may appoint,
in writing, a substitute trustee, who shall thereupon succeed to all the estates, titles,
rights, powers and trusts herein granted to and vested in Trustee. Such appointment may be
made on behalf of Beneficiary by any person who is then the president, or any vice
president, or the cashier or secretary, or branch manager, or a senior representative, or
any other authorized officer or agent of Beneficiary. In the event of the resignation (such
resignation being hereby authorized for any reason) or death of any such substitute trustee,
or his failure, refusal or inability to make such sale or perform such trusts, or, at the
option of Beneficiary, without cause, successive substitute trustees may thereafter, from
time to time, be appointed by Beneficiary in the same manner. Trustee may appoint, in
writing, any one or more Persons as Trustee’s agent and attorney-in-fact to act as Trustee
under him and in his name, place and stead, to perform any one or more acts necessary or
incident to any sale under the power of sale granted under the preceding provisions of this
Subsection 3.2(c), including, without limitation, the posting and filing of any notices, the
conduct of such sale and the execution and delivery of any instruments conveying the
Mortgaged Property so sold, but in the name and on behalf of Trustee. All acts done or
performed by any such agent and attorney-in-fact shall be valid, lawful and binding as if
done or performed by Trustee. Wherever herein the word ATrustee@ is used, the
same shall mean the person who is the duly appointed trustee or substitute trustee hereunder
at the time in question.

(d) Suit. Beneficiary may, or Trustee may upon written request of Beneficiary,
proceed by suit or suits, at law or in equity, to enforce the payment and performance of the
Obligation in accordance with the terms hereof, of the Notes or the other security
instruments, or other documents and/or writings securing and/or evidencing the Obligation,
to foreclose the liens of this Deed of Trust as against all or any part of the Mortgaged
Property and to have all or any part of the Mortgaged Property sold under the judgment or
decree of a court of competent jurisdiction.

(e) Appointment of Receiver. Beneficiary, as a matter or right and without
regard to the sufficiency of the security, and without any showing of insolvency, fraud or
mismanagement on the part of Grantor, and without the necessity of filing any judicial or
other proceeding other than the proceeding for appointment of a receiver, shall be entitled
to the appointment of a receiver or receivers of the Mortgaged Property, or any part
thereof, and of the income, rents, issues and profits thereof.

(f) Possession of Mortgaged Property. Beneficiary may enter upon the Land
included within the Mortgaged Property, take possession of the Mortgaged Property, and
remove the Personal Property included within the Mortgaged Property, or any part thereof,
with or without any responsibility or liability on the part of Beneficiary, take possession
of any property located on or in the Mortgaged Property which is not a part of the Mortgaged
Property and hold or store such property at Grantor’s expense.

(g) Assemble Collateral. Beneficiary may require Grantor to assemble the
Collateral included within the Mortgaged Property, or any part thereof, and make it
available to Beneficiary at a place to be designated by Beneficiary which is reasonably
convenient to Grantor and Beneficiary.

(h) Disposition of Collateral. After notification, if any, as hereafter
provided in this Subsection 3.2(h), Beneficiary may sell, lease or otherwise dispose of, at
the office of Beneficiary, or on the Land, or elsewhere, as chosen by Beneficiary, all or
any part of the Collateral included within the Mortgaged Property, in its then condition, or
following any commercially reasonable preparation or processing, and each sale [as used in
this Subsection 3.2(h), the term “sale” means any such sale, lease, or other disposition
made pursuant to this Subsection 3.2(h)] may be a unit or in parcels, by public or in
private proceedings, and by way of one or more contracts, and, at any sale, it shall not be
necessary to exhibit the Collateral, or part thereof, being sold, leased or otherwise
disposed of. The sale of any part of the Collateral shall not exhaust Beneficiary’s power
of sale, but sales may be made from time to time until the Obligation is paid and performed
in full. Reasonable notification of the time and place of any public sale pursuant to this
Subsection 3.2(h), or reasonable notification of the time after which any private sale is to
be made pursuant to this Subsection 3.2(h), shall be sent to Grantor and to any other person
entitled under the applicable Code to notice. It is agreed that notice sent or given not
less than twenty-one (21) calendar days prior to the taking of the action to which the
notice relates, is reasonable notification and notice for such purposes of this Subsection
3.2(h).

(i) Surrender of Insurance Policies. Beneficiary may surrender the insurance
policies maintained pursuant to Subsection 2.2(p) hereof, or any part thereof, and receive
and apply the unearned premiums as a credit on the Obligation, and, in connection therewith,
Grantor hereby appoints Beneficiary as the agent and attorney-in-fact for Grantor to collect
such premiums.

Section 3.3 Purchase of Mortgaged Property by Beneficiary. If Beneficiary is the
purchaser of the Mortgaged Property, or any part thereof (and it is specifically agreed that
Beneficiary may be the purchaser of the Mortgaged Property, or any part thereof, if permitted by
applicable law), at any sale thereof, whether such sale be under the power of sale hereinabove
vested in Trustee, or upon any other foreclosure of the liens hereof, or otherwise, Beneficiary
shall, upon any such purchase, acquire good title to the Mortgaged Property so purchased, free of
the liens of these presents.

Section 3.4 Operation of Properties by Beneficiary. Should any part of the Mortgaged
Property come into the possession of Beneficiary, whether before or after default, Beneficiary may
use or operate (to the extent allowed under applicable operating arrangements) the Mortgaged
Property for the purpose of preserving it or its value, pursuant to the order of a court of
appropriate jurisdiction, or in accordance with any other rights held by Beneficiary in respect to
the Mortgaged Property. Grantor covenants promptly to reimburse and pay to Beneficiary, at the
place where notes are payable, or at such other place as may be designated by Beneficiary in
writing, the amount of all reasonable expenses (including the cost of any insurance, taxes,
attorney’s fees and other charges) incurred by Beneficiary in connection with its custody,
preservation, use or operation of the Mortgaged Property, together with interest thereon from the
date incurred by Beneficiary at the Highest Lawful Rate, and all such expenses, cost, taxes,
interest and other charges shall be a part of the Obligation. It is agreed, however, that the risk
of loss or damage to the Mortgaged Property is on Grantor, and Beneficiary shall have no liability
whatever for decline or diminution in value of the Mortgaged Property, nor for failure to obtain or
maintain insurance, nor for failure to determine whether any insurance ever in force is adequate as
to amount or as to the risks insured.

Section 3.5 Possession of Property After Foreclosure. In case the liens hereof shall
be foreclosed by Trustee’s sale, or by other judicial or non-judicial action, the purchaser at any
such sale shall receive, as an incident to his ownership, immediate possession of the Mortgaged
Property, or any part thereof so conveyed, and, subsequent to foreclosure, Grantor and Grantor’s
successors shall be considered as tenants at sufferance of the purchaser at foreclosure sale, and
anyone occupying the property after demand made for possession thereof shall be guilty of forcible
detainer and shall be subject to eviction and removal, forcible, or otherwise, with or without
process of law, and all damages by reason thereof are hereby expressly waived.

Section 3.6 Application of Proceeds. The proceeds from any sale, lease or other
disposition made pursuant to this Article 3, any proceeds of Hydrocarbons collected by Beneficiary
pursuant to Article 4, and sums received pursuant to Section 6.5 shall be applied by Trustee, or by
Beneficiary, as the case may be, first to the payment of any and all expenses incurred by the
Trustee or the Beneficiary in foreclosing upon the Property and carrying out such sale (including
any attorneys= fees); second to the payment of any fees assessed by the Trustee, and third to
the payment or prepayment of the Obligation, whether or not matured, as may be determined by the
Beneficiary in its sole discretion until the Obligation is paid in full.

Section 3.7 Abandonment of Sale. In the event a foreclosure hereunder should be
commenced by Trustee in accordance with Subsection 3.2(c), Beneficiary may at any time before the
sale direct Trustee to abandon the sale, and may then institute suit for collection of the
Obligation, and/or for the foreclosure of the liens hereof. If Beneficiary should institute a suit
for the collection of the Obligation, and/or for a foreclosure of the liens hereof, it may at any
time before the entry of a final judgment in said suit dismiss the same, and sell and/or require
Trustee to sell (and the Trustee is hereby expressly authorized to sell) the Mortgaged Property, or
any part thereof, in accordance with the provisions of this Deed of Trust.

Section 3.8 Waiver of Appraisement and Redemption. To the full extent Grantor may
lawfully do so, Grantor agrees that Grantor will not at any time insist upon, plead, claim or take
the benefit or advantage of any appraisement, valuation, stay, extension or redemption laws, now or
hereafter in force, in order to prevent or hinder the enforcement of this Deed of Trust or the
absolute sale of the Mortgaged Property or any part thereof, or the possession thereof by any
purchaser at any such sale, but Grantor, insofar as Grantor now or hereafter may lawfully do so,
hereby waives the benefit of all such laws; provided, however, that the appraisement of any of the
Mortgaged Property is hereby expressly waived or not waived at the option of Trustee and/or
Beneficiary, such option to be exercised prior to or at the time judgment is rendered in any
foreclosure of this Deed of Trust. Grantor also expressly waives, to the extent Grantor may
lawfully do so, all rights to have the Mortgaged Property marshaled upon any foreclosure of this
Deed of Trust.

ARTICLE 4

Section 4.1 Assignment and Additional Security. In addition to the conveyance to
Trustee herein made and to additionally secure the Obligation, Grantor has, effective as of 7:00

ASSIGNED, TRANSFERRED AND CONVEYED, and does hereby ASSIGN, TRANSFER AND CONVEY, unto Beneficiary
all of the following:

(a) All Hydrocarbons, and the proceeds therefrom and products obtained or
processed therefrom (such proceeds and products being herein called
AProceeds@), produced and to be produced from the Mortgaged Property, and all
Rights of Grantor to security interests and Liens securing payment of Proceeds, including,
without limitation, those security interests and Liens provided for in '9.343 of the
Code. Grantor hereby authorizes and empowers Beneficiary to demand, collect and receive
such Hydrocarbons and Proceeds, to endorse and cash any checks and drafts payable to Grantor
or Beneficiary for the account of Grantor received from or in connection with such
Hydrocarbons and Proceeds, to execute any release, receipt, division order, transfer order,
and relinquishment or other instrument that may be required or necessary to collect and
receive such Hydrocarbons and Proceeds, and to exercise any Rights as the holder of security
interests and Liens securing payment of Proceeds. Grantor hereby authorizes and directs all
pipeline companies, gathering companies, and others purchasing such Hydrocarbons or having
in their possession any such Hydrocarbons or Proceeds, to pay and deliver to Beneficiary all
such Hydrocarbons and Proceeds. Grantor agrees that all division orders, transfer orders,
receipts and other instruments which Beneficiary may from time to time execute and deliver
for the purpose of collecting or receipting for Hydrocarbons or Proceeds may be relied upon
in all respects and that the same shall be binding upon Grantor and Grantor’s Successors.
Grantor agrees to execute and deliver all necessary, convenient and appropriate instruments,
including transfer and division orders, which may be required by Beneficiary in connection
with the receipt by Beneficiary of such Hydrocarbons or Proceeds and to indemnify and keep
and hold Beneficiary free and harmless from all parties whomsoever having or claiming an
adverse interest in such Hydrocarbons and Proceeds and in this respect agrees to pay all
expenses, costs, charges and attorneys’ fees that may be incurred by Beneficiary as to any
of such matters.

(b) All proceeds hereafter payable to or to become payable to Grantor or to which
Grantor is entitled under all gas sales or exchange contracts, all oil, distillate, or
condensate sales or exchange contracts, all gas transportation contracts, and all gas
processing contracts now or hereafter to become a part of the Mortgaged Property.

(c) All amounts, sums, revenues, and income which become payable to Grantor from any of
the Mortgaged Property (including any after-acquired properties) or under any contract,
present or future, relating to, any gas pipeline system and processing plant or unit now or
hereafter constituting a part of the Mortgaged Property.

(d) All lease bonus, delay rentals, royalties and shut-in gas royalties which become
payable to Grantor from any of the Mortgaged Property.

Section 4.2 Transfer Orders. Grantor agrees to execute such transfer orders, payment
orders, division orders and other instruments as may be needed by Beneficiary or requested by it
incident to its having all assigned payments made direct to it at its office in Midland, Texas.
Grantor hereby authorizes and directs all such pipeline companies, purchasers, transporters and
other parties owing moneys to Grantor under contracts herein assigned, to pay such amounts direct
to Beneficiary as follows:

AMERICAN STATE BANK

620 North Grant Avenue

Odessa, Texas 79761

and such authorization shall continue until this Deed of Trust is released. Beneficiary is
authorized to collect, receive, and give receipt for all such amounts, and no party making payment
shall have any responsibility to see to the application of any funds paid to the Beneficiary but
shall be fully protected in making such payment to Beneficiary under the assignments herein
contained. Should Beneficiary bring suit against any third party for collection of any amounts or
sums included within this assignment (and Beneficiary shall have the right to bring any such suit),
it may sue either in its own name or in the name of Grantor.

Section 4.3 Payment of Proceeds. In the event that, for its convenience, Beneficiary
should elect with respect to particular properties or contracts not to exercise immediately its
right to receive Hydrocarbons or proceeds, then the purchasers or other persons obligated to make
such payment shall continue to make payment to Grantor until such time as written demand has been
made upon them by Beneficiary or Trustee that payment be made directly to Beneficiary. Such
failure to notify shall not in any way waive the right of Beneficiary to receive any payments not
theretofore paid out to Grantor before the giving of written notice. In this regard, in the event
payments are made directly to Beneficiary, and then, at the request of Beneficiary payments are,
for a period of time, paid to Grantor, Beneficiary shall nevertheless have the right, effective
upon written notice, to require that future payments be again made to Beneficiary.

Section 4.4 Proceeds Held in Trust by Grantor. If under any existing gas sales or
exchange agreements or products sales or exchange contracts, other than division orders or transfer
orders, or under any gas transportation contract, any proceeds are required to be paid by the
purchaser or transporter direct to Grantor so that under such existing agreements payment cannot be
made to Beneficiary in the absence of foreclosure, then Grantor’s interest in all proceeds under
such sales agreement and in all other proceeds which for any reason may be paid to Grantor shall,
when received by Grantor, constitute trust funds in his hands and shall be immediately paid over to
Beneficiary, if Beneficiary has requested that such payments be delivered to it under this
assignment.

Section 4.5 Limitation of Liability of Beneficiary and Trustee. Beneficiary is
hereby absolved from all liability for failure to enforce collection of the proceeds and amounts
assigned under Section 4.1 above and from all other responsibility in connection therewith, except
the responsibility to account to the person legally entitled thereto (by application upon the
Obligation or otherwise) for funds actually received. Grantor agrees to indemnify and hold
harmless Trustee and Beneficiary against any and all liabilities, actions, claims, judgments,
costs, charges, and attorney’s fees by reason of the assertion that they or either of them have
received, either before or after payment and performance in full of the Obligation, funds from the
production of hydrocarbons claimed by third persons, and the Trustee and Beneficiary shall each
have the right to compromise and adjust any such claims, actions, and judgments, and in addition to
the rights to be indemnified as herein provided, all amounts paid by Trustee or by Beneficiary in
compromise, satisfaction, or discharge of any such claim, action or judgment, and all court costs,
attorney’s fees, and other expenses of every character incurred by Trustee or by Beneficiary,
pursuant to the provisions of this section, shall be demand obligations owing by Grantor and shall
bear interest at the Highest Lawful Rate from date of expenditure until paid and shall be secured
by the liens created and granted by this Deed of Trust.

Section 4.6 Duty to Pay Obligation. Nothing contained herein shall limit Grantor’s
absolute duty to make payment when due of the Obligation when the Proceeds received by Beneficiary
pursuant to Section 4.1 hereof are insufficient to pay the same, and receipt of Proceeds under said
Section 4.1 shall be in addition to all other security now or hereafter existing to secure payment
of the Obligation.
