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) in the state 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) of any state, such sale of
the Mortgaged Property, or any part thereof, may be made in any County (or judicial

posted in such places and for such time periods and after all Persons entitled to notice
thereof have been sent such notice, all as required by 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. Any such sale may be as a whole or in
such parcels as Trustee may select. After such sale, Trustee shall make to the purchaser or
purchasers thereunder good and sufficient deeds and assignments, in the name of Grantor,

with general warranty of title (subject to the Liens, if any, in favor of Senior Lender as
set forth in the Subordination Agreement) 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 the 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
deeds 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, the 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. Wherever herein the word
“Trustee” is used, the same shall mean the Person who is the duly appointed trustee or
substitute trustee hereunder at the time in question.

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 hereof, being sold, leased or otherwise
disposed of. The Sale of any part of the Collateral shall not exhaust Beneficiary’s power of

Property come into the possession of Beneficiary, whether before or after Default, Beneficiary may
use or operate 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 the Note is 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, attorneys fees of the Beneficiary 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 except to the extent directly resulting from Beneficiary’s gross negligence or willful
misconduct, nor for failure to obtain or maintain insurance, nor for failure to determine whether
any insurance ever in force is adequate as to the 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 Three, any proceeds of Hydrocarbons collected by
Beneficiary pursuant to Article Four, and sums received pursuant to Section 5.5 shall be applied by
Trustee, or by Beneficiary, as the case may be, 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 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.
In the event Grantor cannot waive his right to redemption under applicable state law, Grantor
agrees to limit said redemption period to the shortest legal time.

ARTICLE FOUR

ASSIGNMENT OF PRODUCTION

Section 4.1. Additional Security. Subject to the terms of the Subordination Agreement
(defined below), to additionally secure the Obligation, Grantor has, effective as of 7:00 A.M.,
local time, on August 1, 2007, at the site of each of the Subject Interests, 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 process
therefrom (such proceeds and products being herein called “Proceeds”), produced and to be
produced from the Mortgaged property, and 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 and 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. 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 attorney’s fees
that may be incurred by Beneficiary as to any 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 are 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:

BASELINE CAPITAL, INC. 5

08 West Wall, Suite 775

Midland, Texas 79701

and such authorization shall continue until this Deed of Trust is released. Beneficiary is
authorized to collect, receive 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. Payments 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 direct 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 direct to Beneficiary, and then, at the request of Beneficiary payments are, for
a period or periods 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.

Rights and Liens hereunder or the liability of Grantor or any other party liable for payment and

Beneficiary, and Grantor shall, upon request of Beneficiary, make, execute, acknowledge and deliver
any and all additional assignments and documents as may be necessary from time to time to enable
Beneficiary to collect and receipt for any such sums. Beneficiary shall not be, under any
circumstances, liable or responsible for failure to collect, or exercise diligence in the

statement, Grantor is the debtor and Beneficiary is the secured party. The addresses shown in

of either party, whether made before or after the institution of any legal proceedings, but prior
to the rendering of any judgment in that proceeding, all disputes, claims and controversies between

documents or otherwise, including without limitation contract disputes and tort claims, shall be
resolved by binding arbitration pursuant to the Commercial Rules of the American Arbitration

be conducted in Midland, Midland County, Texas. No act to take or dispose of any Collateral shall
constitute a waiver of this arbitration agreement or be prohibited by this arbitration agreement.

controversy to seek, use, and employ ancillary, or preliminary rights and/or remedies, judicial or
otherwise, for the purposes of realizing upon, preserving, protecting, foreclosing upon or

reasonableness of an act, or exercise of any right or remedy concerning any Collateral, including
any claim to rescind, reform, or otherwise modify any agreement relating to the Collateral, shall
also be arbitrated; provided, however that no arbitrator shall have the right or the power to
enjoin or restrain any act of either party. Judgment upon any award rendered by any arbitrator may
be entered in any court having jurisdiction. The statute of limitations, estoppel, waiver, laches
and similar doctrines which would otherwise be applicable in an action brought by a party shall be
applicable in any arbitration proceeding, and the commencement of an arbitration proceeding shall
be deemed the commencement of any action for these purposes. The Federal Arbitration Act (Title 9
of the United States Code) shall apply to the construction, interpretation, and enforcement of this

SUBORDINATION AGREEMENT

THIS SUBORDINATION AGREEMENT (this “Agreement”) is made and entered into as of August 1, 2008
by and among BaseLine Capital, Inc. (“Subordinated Lender”), Permian Legend Petroleum LP
(“Borrower”), Permian Legend LLC (“Guarantor”) and American State Bank (“Senior Lender”), with
reference to the following facts:

A. Borrower has executed a promissory note dated August 1, 2007, being made payable to the
order of the Subordinated Lender in the original principal amount of $500,000.00 (the “Subordinated
Note”). The Subordinated Note evidences an extension of credit from Subordinated Lender to Borrower
pursuant to that certain Loan Agreement dated effective of even date herewith (the “Subordinated
Loan Agreement”).

B. Borrower and Senior Lender have entered into a Loan Agreement, Promissory Note, and
security documents, all dated the same date as this Agreement (collectively, as amended, restated,
or supplemented, the “Senior Loan Documents”), pursuant to which Senior Lender will advance to
Borrower in the form of one or more credit facilities in an aggregate amount of up to
$1,675,000.00.

C. The Subordinated Loan Agreement provides that the Subordinated Lender shall be entitled to
one or more assignments of an interest in certain of the property pledged to secure the debt
created under the Senior Loan Documents (whether one or more, the “Assignment”), which Assignment
will be executed by Borrower of even date herewith and held by the Subordinated Lender until the
Subordinated Lender is entitled thereto under the Subordinated Loan Agreement.

D. Guarantor is the sole general partner of Borrower and has agreed to guarantee both the
Senior Debt and the Subordinated Debt.

E. As an inducement and a condition to Senior Lender to extend the Senior Debt to Borrower,
Senior Lender has required that Subordinated Lender agree to the terms and conditions of, and
execute and deliver this Agreement.

NOW, THEREFORE, for and in consideration of the mutual covenants and promises of this
Agreement, and for other consideration, the receipt and adequacy of which are hereby acknowledged,
Borrower, Guarantor, Subordinated Lender and Senior Lender agree as follows:

1. Definitions. As used in this Agreement the following terms have the following
meanings (other terms are defined above or elsewhere herein):

"Debtor Relief Laws” means Title 11 of the United States Code, as amended from time to time,
and any and all applicable laws regarding liquidation, conservatorship, bankruptcy, assignment for
the benefit of creditors, moratorium, rearrangement, receivership, suspension of payments,
insolvency, reorganization, or similar laws affecting the rights of creditors generally, as in
effect from time to time and as hereafter amended.

"Equipment Collateral” means the equipment, inventory, pipe and other personal property assets
of Borrower pledged to Subordinated Lender under the Subordinated Loan Documents which are not
located on the oil and gas properties covered by liens in favor of the Senior Lender under the
Senior Loan Documents.

"Event of Default” means an “Event of Default” under and as defined in the Senior Loan
Documents.

"Person” means any individual, partnership, limited partnership, corporation, limited
liability company, business trust, joint stock company, trust, unincorporated association, joint
venture, syndicate, or other entity or organization of whatever nature.

"Senior Debt” means the principal, interest, fees, and any and all costs and expenses owed by
Borrower to Senior Lender under the Senior Loan Documents, and all extensions and renewals thereof,
as well as any additions thereto, including, but not limited to, any future advances to be extended
by Senior Lender to Borrower up to the maximum amount of $1,675,000.00, plus accrued interest and
amounts owed for fees, costs and expenses.

"Subordinated Debt” means the principal of and interest on the Subordinated Note and all other
debt of Borrower to Subordinated Lender up to the maximum amount of $500,000.00, plus accrued
interest and amounts owed for fees, costs and expenses.

"Subordinated Loan Documents” means the Subordinated Loan Agreement, Subordinated Note and all
related agreements, documents and instruments.

2. Subordination. Until the Senior Debt is paid in full, (a) any payment in respect of
the Subordinated Debt is and shall be expressly junior and subordinated in right of payment to all
amounts due and owing upon all Senior Debt outstanding from time to time, (b) except as expressly
provided in Section 3 hereof, Subordinated Lender may not receive or accept any payment in any form
with respect to the Subordinated Debt and (c) any liens or security interests now or hereafter
securing payment of any and all Subordinated Debt are expressly subordinated to the liens and
security interests now or hereafter securing the Senior Debt; in each case, including all other
notes and security instruments executed in connection therewith, and each amendment, extension,
refinancing, restatement or other modification thereof. Subordinated Lender may require Borrower or
Guarantor to pledge, mortgage or grant liens on their properties to Subordinated Lender so long as
Senior Lender also has a lien on or security interest in such property or has determined in its
discretion not to have such lien or security interest. Senior Lender acknowledges and agrees that
it has determined not to have and does not have a lien on or security interest in any of the
Equipment Collateral, and that the Subordinated Lender’s lien on and security interest in the
Equipment Collateral is not subject to the subordination provided in this Agreement.

3. Payment on Subordinated Debt. If the Payment Conditions (as hereinafter defined in
this Section 3) are satisfied, Borrower may pay Subordinated Lender on the Subordinated Note and
under the Subordinated Loan Agreement pursuant to the terms thereof (the “Permitted Payments”). The
term “Payment Conditions,” means that: (i) no Event of Default has occurred and is continuing under
the Senior Loan Documents, and (ii) no Event of Default would result under the Senior Loan
Documents from the making of any such Permitted Payments. If the Payment Conditions are not
satisfied with respect to any calendar month, such that the Permitted Payments attributable to such
calendar month may not be made pursuant to this Agreement, then such Permitted Payments shall
continue to be an obligation of Borrower to Subordinated Lender, expressly subject to the rights of
the Senior Lender, and subject to the terms of this Agreement. If the Payment Conditions are not
satisfied with respect to any calendar month, resulting in the Permitted Payments for that month
not being made, then at the end of any subsequent calendar month, if the Payment Conditions are
satisfied based on a cumulative calculation that includes all unpaid Permitted Payments, then the
sum of the unpaid Permitted Payments for all such previous calendar months may be paid.

4. Proceedings Against Borrower or Guarantor. Until the Senior Debt is paid in full,
Subordinated Lender may not, without the consent of the Senior Lender (which consent will not be
