To the best of Debtor's knowledge such xxxxx are in fact bottomed under and are producing from, and the well bores are wholly within, the lands described in Exhibit “A”.

With respect to each of the oil and gas leases and xxxxx described in Exhibit “A,” Debtor’s share of development and operating costs with respect to the portion of the Land covered thereby as described in Exhibit “A”, without regard to pooling and unitization, is not greater than the “Working Interest” or “WI” specified in Exhibit “A”; and Debtor’s share of the gross production of all oil, gas and other Hydrocarbons produced, saved and marketed from said Land, without regard to pooling and unitization, is no less than the “Net Revenue Interest” or “NRI” specified in Exhibit “A”.

2. Neither Debtor, nor to the best of Debtor's knowledge its predecessors in title, have entered into or are subject to any agreement or arrangement (including “take or pay” or similar arrangements) nor to the best of Debtor's knowledge is the Collateral subject to any such agreement or arrangement, to deliver Hydrocarbons produced or to be produced from the Collateral at some future time without then or thereafter receiving full payment therefor.

Debtor is not a party to any litigation or administrative proceeding, nor, to the best of Debtor’s knowledge, is any litigation, administrative proceeding or investigation threatened against Debtor or the Collateral, that asserts or alleges that Debtor or its predecessors in title to the Collateral violated or are violating Environmental Laws or that Debtor or such predecessors are required to clean up, remove or take remedial or other responsive action due to the use, storage, treatment, disposal, discharge, leaking or release of any Hazardous Substances or Solid Waste (as such terms are hereinafter defined). Neither Debtor nor to the best of Debtor's knowledge such predecessors or any part of the Collateral is subject to any judgment, decree, order or citation related to or arising out of Environmental Laws and Debtor has not been named or listed as a potentially responsible party by any governmental or other entity in a matter arising under or relating to any Environmental Laws. This representation shall 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 Collateral or to Debtor.

2. Debtor undertook, at the time of acquisition of the Collateral, all appropriate inquiry into the previous ownership and uses of the Collateral consistent with good commercial and industry practice. To the best of Debtor's knowledge no Hazardous Substances or Solid Waste have been disposed of or otherwise released on, to or from the Collateral, except in full compliance with all Environmental Laws. The use which Debtor makes and intends to make of the Collateral will not result in the use or storage of any Hazardous Substances or Solid Waste on, in or in connection with the Collateral, or disposal from the Collateral, except in full compliance with all Environmental Laws, or result in any requirement that Debtor apply for or obtain a permit under RCRA (as hereinafter defined) or other Environmental Law for the treatment, storage or disposal of Hazardous Substances or Solid Waste. To the best of Debtor's knowledge there are no regulated underground storage tanks located on or in the Collateral.

Debtor shall promptly, and in no event later than 3 days after becoming aware, notify Secured Party (1) if any representation or warranty of Debtor contained in this Agreement is discovered to be or becomes untrue, or (2) Debtor fails to perform or comply with any covenant or agreement contained in this Agreement or it is reasonably anticipated that Debtor will be unable to perform or comply with any covenant or agreement contained in this Agreement. Debtor shall cause all the representations and warranties of Debtor contained in this Agreement to be true and correct in all material respects from time to time and all times.

F. Defense of Title. If the title or interest of Debtor or Secured Party to the Collateral or any part thereof, or the lien or encumbrance created by this Instrument, or the rights or powers of Secured Party hereunder, shall be attacked, either directly or indirectly, or if any legal proceedings are commenced against Debtor or the Collateral, Debtor shall promptly give written notice thereof to Secured Party and at Debtor’s own expense shall take all reasonable steps diligently to defend against any such attack or proceedings, employing attorneys acceptable to Secured Party. Secured Party may take such independent action in connection therewith as it may in its discretion deem advisable, and all costs and expenses, including attorneys’ fees and legal expenses, incurred by or on behalf of Secured Party in connection therewith shall be a demand obligation owing by Debtor to Secured Party and shall bear interest at the Default Rate (as defined in the Credit Agreement) until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Instrument.

G. Environmental Matters. Debtor shall comply with all Environmental Laws and shall maintain and obtain all permits, licenses and approvals required under Environmental Laws. Debtor shall not cause or permit the Collateral or Debtor to be in violation of, or do anything or permit anything to be done that will subject the Collateral, Debtor or Secured Party to any remedial obligations under any applicable Environmental Laws, assuming disclosure to the applicable governmental authorities of all relevant facts, conditions and circumstances, if any, pertaining to the Collateral or otherwise. Debtor shall promptly notify Secured Party in writing of any existing, pending or threatened investigation or inquiry by any governmental authority in connection with any applicable Environmental Laws. Debtor shall take all steps necessary to determine that no Hazardous Substances or Solid Waste have been used or stored on, in or in connection with the Collateral, or disposed of or otherwise released on, to or from the Collateral, except in full compliance with all Environmental Laws. Debtor shall not cause or permit the use or storage of Hazardous Substances or Solid Waste on, in or in connection with the Collateral or disposal of Hazardous Substances or Solid Waste from the Collateral, except in full compliance with all Environmental Laws, or make any use of the Collateral that results in any requirement that Debtor apply for or obtain a permit under RCRA or other Environmental Law for the treatment, storage or disposal of Hazardous Substances or Solid Waste. Debtor covenants and agrees to keep or cause the Collateral to be kept free of any Hazardous Substances or Solid Waste except in full compliance with all Environmental Laws, and, promptly upon the discovery that the presence of any such substance on the Collateral is not in full compliance, to remove the same (or if removal is prohibited by law, to take whatever action is required by law) at its sole expense. Upon Secured Party’s reasonable request based upon the condition of or operations on the Collateral, at any time and from time to time, Debtor shall provide at Debtor’s sole expense inspections, tests and audits of the Collateral from an engineering or consulting firm approved by Secured Party indicating the presence or absence of Hazardous Substances or Solid Waste on, in or under the Collateral that are not in compliance with applicable Environmental Laws. If Debtor fails to provide same after 20 days’ notice, Secured Party may order same, and Debtor grants to Secured Party and its respective employees, agents, contractors, designees and consultants access to the Collateral and a license (which is coupled with an interest and irrevocable) to perform inspections, tests and audits. The cost of such inspections, tests and audits shall be a demand obligation owing by Debtor to Secured Party and shall bear interest at the Default Rate until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Instrument. Nothing contained herein shall relieve Debtor from conducting its own inspections, tests and audits or taking any other steps necessary to comply with all Environmental Laws, nor shall anything contained herein be construed to imply or impose any duty on Secured Party concerning Debtor’s compliance or noncompliance therewith. Secured Party’s rights under this paragraph are for the sole purpose of protecting Secured Party’s security for the repayment of the Obligations and shall not under any circumstances be construed as granting the right to participate or constitute participation in the management of the Collateral or the business conducted thereon.

H. Change in Structure. Debtor shall not cause or permit any change to be made in its name, identity, entity structure, organizational identification number or state of organization,

unless Debtor shall have notified Secured Party of such change at least thirty days prior to the effective date of such change, and shall have first taken all action required by Secured Party for the purpose of further perfecting or protecting the security interest in favor of Secured Party in the Collateral. In any notice furnished pursuant to this Subsection 2.2-H, Debtor shall expressly state that the notice is required by this Instrument and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of Secured Party’s security interest in the Collateral.

I. Further Assurances. Debtor shall execute, acknowledge and deliver, or cause to be executed, acknowledged or delivered, to Secured Party such other and further instruments and do such other acts as in the reasonable opinion of Secured Party may be necessary or desirable to effect the intent of this Instrument, promptly upon request of Secured Party and at Debtor’s expense.

Section 2.3 Costs, Expenses and Indemnities. Debtor agrees to pay and indemnify Secured Party as follows:

A. Costs and Expenses. Debtor shall indemnify Secured Party from and reimburse and pay Secured Party for all fees, costs and expenses (including attorneys’ fees, court costs and legal expenses and consultant’s and expert’s fees and expenses), incurred or expended by Secured Party in connection with (1) the breach by Debtor of any representation or warranty contained in this Instrument, the Credit Agreement, the Note or any other documents and instruments evidencing, securing or otherwise relating to the Obligations, (2) the failure by Debtor to perform any agreement, covenant, condition, indemnity or obligation contained in this Instrument, the Credit Agreement, the Note or any other documents and instruments evidencing, securing or otherwise relating to the Obligations, (3) Secured Party’s exercise of any of its rights and remedies under this Instrument, the Credit Agreement, the Note and the other documents and instruments evidencing, securing or otherwise relating to the Obligations, or (4) the protection of the Collateral and the liens thereon and security interests therein. All such fees, costs and expenses shall be a demand obligation owing by Debtor to Secured Party and shall bear interest at the Default Rate until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Instrument. The liabilities of Debtor as set forth in this Section 2.3-A shall survive the termination of this Instrument.

B. Indemnity. Debtor shall indemnify and hold harmless Secured Party and persons or entities owned or controlled by or affiliated with Secured Party and their respective directors, officers, shareholders, partners, employees, consultants and agents (herein individually, an “Indemnified Party,” and collectively, “Indemnified Parties”) from and against, and reimburse and pay Indemnified Parties with respect to, any and all claims, demands, liabilities, losses, damages (including actual, consequential, exemplary and punitive damages), causes of action, judgments, penalties, fees, costs and expenses (including attorneys’ fees, court costs and legal expenses and consultant’s and expert’s fees and expenses), of any and every kind or character, known or unknown, fixed or contingent, that may be imposed upon, asserted against or incurred or paid by or

on behalf of any Indemnified Party on account of, in connection with, or arising out of (1) any bodily injury or death or property damage occurring in or upon or in the vicinity of the Collateral through any cause whatsoever, (2) any act performed or omitted to be performed hereunder or the breach of or failure to perform any warranty, representation, indemnity, covenant, agreement or condition contained in this Instrument, the Credit Agreement, the Note or any other documents and instruments evidencing, securing or relating to the Obligations, (3) any transaction, act, omission, event or circumstance arising out of or in any way connected with the Collateral or with this Instrument, the Credit Agreement, the Note or any other documents and instruments evidencing, securing or relating to the Obligations, and (4) the violation of or failure to comply with any statute, law, rule, regulation or order, including Environmental Laws and statutes, laws, rules, regulations and orders relating to Hazardous Substances or Solid Waste. Without limiting the generality of the foregoing, it is the intention of Debtor and Debtor agrees that the foregoing indemnities shall apply to each Indemnified Party with respect to claims, demands, liabilities, losses, damages (including actual, consequential, exemplary and punitive damages), causes of action, judgments, penalties, fees, costs and expenses (including attorneys’ fees, court costs and legal expenses and consultant’s and expert’s fees and expenses) of any and every kind or character, known or unknown, fixed or contingent, that in whole or in part are caused by or arise out of the negligence of such Indemnified Party; however, such indemnities shall not apply to any Indemnified Party to the extent the subject of the indemnification is caused by or arises out of the gross negligence or willful misconduct of such Indemnified Party. The foregoing indemnities shall not terminate upon the release, foreclosure or other termination of this Instrument, but shall survive the foreclosure of the liens and security interests created by this Instrument or conveyance in lieu of foreclosure and the repayment and performance of the Obligations and the discharge and release of the liens and security interest created by this Instrument and the other instruments and documents evidencing, securing or relating to the Obligations. Any amount to be paid hereunder by Debtor to Secured Party or for which Debtor has indemnified an Indemnified Party shall be a demand obligation owing by Debtor to Secured Party and shall bear interest at the Default Rate until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Instrument. The rights, powers and remedies herein conferred are cumulative, and not exclusive, of any and all other rights, powers and remedies existing at law or in equity (including rights, powers and remedies under Environmental Laws) or provided for in any other documents or instruments evidencing, securing or relating to the Obligations and nothing in this paragraph or elsewhere in this Instrument or in any other documents or instruments evidencing, securing or relating to the Obligations shall limit or impair any rights, powers or remedies of Secured Party under any Environmental Laws, including any rights of contribution or indemnification available thereunder. The liabilities of Debtor as set forth in this Section 2.3-B shall survive the termination of this Instrument.

Section 2.4 Performance by Secured Party. Debtor agrees that, if Debtor fails to perform any act which Debtor is required to perform hereunder, Secured Party may, but shall not be obligated to, perform or cause to be performed such act, and any expense so incurred by Secured Party in connection therewith shall be a demand obligation owing by Debtor to Secured Party and shall bear interest at the Default Rate until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Instrument, and Secured Party

shall be subrogated to all of the rights of the party receiving such payment. Debtor hereby irrevocably appoints Secured Party as Debtor’s attorney-in-fact and proxy, with full authority in the place and stead of Debtor and in the name of Debtor or otherwise, from time to time to take any action and to execute any instrument which Secured Party may deem necessary or advisable to accomplish the purposes of this Agreement. Such appointment is coupled with an interest and shall be irrevocable from the date hereof and so long as any part of the Obligations is outstanding.

ARTICLE III

Collection of Proceeds of Production

Section 3.1 Assignment of Proceeds. Pursuant to paragraph C of the granting clause of this Instrument, Secured Party is absolutely assigned and entitled to receive all of the severed and extracted Hydrocarbons produced from or allocated or attributed to all of the Collateral, together with all of the proceeds thereof and payments in lieu thereof such as “take or pay” or similar payments. Debtor acknowledges and agrees that said assignment is intended to be an absolute and unconditional assignment and not merely a pledge of or creation of a security interest in said Hydrocarbons and proceeds or an assignment as additional security. Debtor shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered, transfer orders or letters-in-lieu thereof directing all pipeline companies or other purchasers of Hydrocarbons to make payments directly to Secured Party. All parties producing, purchasing, receiving or having in their possession any such Hydrocarbons or proceeds are hereby authorized and directed by Debtor to treat and regard Secured Party as the party entitled in Debtor’s place and stead to receive such Hydrocarbons and proceeds; and said parties shall be fully protected in so treating and regarding Secured Party and shall be under no obligation to see to the application by Secured Party of any such proceeds received by it. For its convenience, Secured Party may, with respect to any or all such Hydrocarbons or proceeds, permit Debtor to receive such Hydrocarbons or proceeds until such time as Secured Party shall have made written demand therefor. Such election by Secured Party shall not in any way waive the right of Secured Party to demand and receive such Hydrocarbons and proceeds thereafter allocated or attributed to the Collateral and shall not in any way diminish the absolute and unconditional right of Secured Party to receive all of such Hydrocarbons and proceeds and cash proceeds not theretofore expended or distributed by Debtor. Any such Hydrocarbons or proceeds received by Debtor shall, when received, constitute trust funds in Debtor’s hands and shall be held by Debtor for the benefit of Secured Party. Debtor hereby agrees that upon the first to occur of either (A) written demand of Secured Party, or (B) the occurrence of any event which constitutes an Event of Default (as hereinafter defined) or which upon the giving (or receiving) of notice or lapse of time, or both, would constitute such an Event of Default, all cash, proceeds, instruments and other property, of whatever kind or character, received by Debtor on account of the Collateral, whether received by Debtor in the exercise of its collection rights hereunder or otherwise, shall, in accordance with instructions then given by Secured Party, be remitted to Secured Party or deposited to an account designated by Secured Party, in the form received (properly assigned or endorsed to the order of Secured Party or for collection and in accordance with Secured Party’s instructions) not later than the first banking business day following the day of receipt, to be applied as provided in Section 3.2 hereof and, until so applied, may be held by Secured Party in a separate account on which Debtor may not draw. Debtor agrees not to commingle any such property, following the receipt of any such demand from Secured Party or the occurrence of an Event of Default, with any of its other funds or property and agrees to hold the same upon an express trust for Secured Party until remitted to Secured Party.

Section 3.2 Application of Proceeds. Secured Party shall apply all of the proceeds received pursuant to Section 3.1 hereof in satisfaction of the Obligations as provided below, unless otherwise agreed to by Secured Party and Debtor. All such proceeds received and to be applied by Secured Party up to the close of business on the last day of each calendar month shall be applied by Secured Party on or before the fifth business day of the next succeeding calendar month as follows (with any balance remaining after such application to be paid to Debtor):

A. First, to the payment to Secured Party of all outstanding or unreimbursed fees, costs and expenses incurred by Secured Party pursuant hereto, and any part of the Obligations not evidenced by written instrument, including all charges and penalties, including interest thereon, due Secured Party;

B. Second, to the payment of all interest accrued on the Obligations; and

C. Third, to the payment or prepayment of the principal of the Obligations in any order the Secured Party may elect from time to time;

If any date of application specified above shall be a Saturday, Sunday or legal holiday, the proceeds to be applied by Secured Party pursuant to this Section 3.2 shall be applied on the business day next succeeding such date which is not a Saturday, Sunday or legal holiday, and the amount to be applied as described above shall be the amount accrued up to such date. If the proceeds received by Secured Party pursuant to Section 3.1 during any month are not sufficient to make the minimum payments of principal of and interest on the Obligations required by the terms of the Credit Agreement or the Note, then Debtor on or before the due date shall make payment to Secured Party of an amount sufficient when added to such proceeds received to make the minimum required payments of principal and interest of the Obligations.

Section 3.3 Inclusion in Sale. Upon any sale of any of the Collateral pursuant to Article V hereof and expiration of any mandatory redemption periods, the Hydrocarbons thereafter produced from or attributed to the part of the Collateral so sold, and the proceeds thereof, shall be included in such sale and shall pass to the purchaser free and clear of the provisions of this Article III.

Section 3.4 No Liability in Secured Party. Secured Party is hereby absolved from all liability for failure to enforce collection of any such proceeds and from all other responsibility in connection therewith, except the responsibility to account to Debtor for proceeds actually received.

Section 3.5 Indemnity. Debtor shall indemnify Secured Party against all claims, actions, liabilities, judgments, costs, attorneys’ fees or other charges of every kind or nature (“Claims”) made against or incurred by Secured Party as a consequence of the assertion, either before or after the payment in full of the Obligations, that Secured Party received Hydrocarbons or proceeds pursuant to this Article III which were claimed by third persons. Secured Party shall have the right to employ attorneys and to defend against any Claims, and unless furnished with reasonable indemnity, Secured Party shall

have the right to pay or compromise and adjust all Claims. Debtor shall indemnify and pay to Secured Party all such amounts as may be paid with respect thereto or as may be successfully adjudicated against Secured Party, and such amounts shall be a demand obligation owing by Debtor to Secured Party and shall bear interest at the Default Rate until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Instrument. The liabilities of Debtor as set forth in this Section 3.5 shall survive the termination of this Instrument.

Section 3.6 Rights of Secured Party. Secured Party shall have the immediate and continuing right to demand, collect, receive and receipt for all production, proceeds and payments assigned hereunder, and Secured Party is hereby appointed agent and attorney-in-fact of Debtor (which appointment is coupled with an interest and is irrevocable) for the purpose of executing any release, receipt, division order, transfer order, relinquishment or other instrument that Secured Party deems necessary in order for Secured Party to collect and receive such production, proceeds and payments. In addition, Debtor agrees that, upon the request of Secured Party, it will promptly execute and deliver to Secured Party such transfer orders, payment orders, division orders and other instruments as Secured Party may deem necessary, convenient or appropriate in connection with the payment and delivery directly to Secured Party of all proceeds, production, and payments assigned hereunder. Debtor hereby authorizes and directs that, upon the request of Secured Party, all pipeline companies, purchasers, transporters and other parties now or hereafter purchasing oil, gas or other mineral production produced from or allocated or attributed to the Collateral or any other interest of Debtor (whether now owned or hereafter acquired by operation of law or otherwise), in, to or relating to the Land or to any of the estates, property, rights or other interests included in the Collateral, or any part thereof, or now or hereafter having in their possession or control any production from or allocated to the Collateral or any other interest of Debtor (whether now owned or hereafter acquired by operation of law or otherwise), in, to or relating to the Land or to any of the estates, property, rights or other interests included in the Collateral, or any part thereof, or the proceeds therefrom, or now or hereafter otherwise owing monies to Debtor under contracts and agreements herein assigned, shall, until Secured Party directs otherwise, pay and deliver such proceeds, production or amounts directly to Secured Party at Secured Party’s address set forth in the introduction to this Instrument, or in such other manner as Secured Party may direct such parties in writing, and this authorization shall continue until the assignment of production and proceeds contained herein is released and reassigned. Debtor agrees that all division orders, transfer orders, receipts and other instruments that Secured Party may from time to time execute and deliver for the purpose of collecting and receipting for such proceeds, production or payments may be relied upon in all respects, and that the same shall be binding upon Debtor and its successors and assigns. No payor making payments to Secured Party at its request under the assignment of production and proceeds contained herein shall have any responsibility to see to the application of any of such funds, and any party paying or delivering proceeds, production or amounts to Secured Party under such assignments shall be released thereby from any and all liability to Debtor to the full extent and amount of all payments, production or proceeds so delivered. Should Secured Party bring suit against any third party for collection of any amounts or sums included within the assignment of production and proceeds contained herein (and Secured Party shall have the right to bring any such suit), it may xxx either in its own name or in the name of Debtor, or both.

Section 3.7 Change of Connection. Should any purchaser taking the production from the Collateral or any other interest of Debtor (whether now owned or hereafter acquired by operation of law or otherwise), in, to or relating to the Land or to any of the estates, property, rights or other interests included in the Collateral, or any part thereof, fail to make any payment promptly to Secured Party, in accordance with the assignment of production and proceeds herein made, then Secured Party, to the fullest extent permissible under applicable law, shall have the right to demand a change of connection and to designate another purchaser with whom a new connection may be made, without any liability on the part of Secured Party in making such selection; and failure of Debtor to consent to and promptly effect such change of connection shall constitute an Event of Default under Article V below.

Section 3.8 No Delegation or Assumption. Nothing in this Instrument shall be deemed or construed to create a delegation to or assumption by Secured Party, of the duties and obligations of Debtor under any agreement or contract relating to the Collateral or any portion thereof, and all of the parties to any such contract shall continue to look to Debtor for performance of all covenants and other obligations and the satisfaction of all representations, warranties, covenants, indemnities and other agreements of Debtor thereunder, notwithstanding the assignment of production and proceeds contained herein or the exercise by Secured Party, prior to foreclosure, of any of its rights hereunder or under applicable law.

Section 3.9 Cumulative. The assignment of production and proceeds contained herein shall not be construed to limit in any way the other rights and remedies of Secured Party hereunder, including its right to accelerate the indebtedness evidenced by the Obligations upon an Event of Default and the other rights and remedies herein conferred, conferred in the other documents and instruments evidencing, securing or relating to the Obligations, or conferred by operation of law. Monies received under the assignment of production and proceeds contained herein shall not be deemed to have been applied in payment of the Obligations unless and until such monies actually are applied thereto by Secured Party.

ARTICLE IV

Termination and Release

Section 4.1 Release Upon Termination. If all of the Obligations shall be paid in full and otherwise satisfied pursuant to the terms and conditions of this Instrument and the other documents and instruments evidencing, securing or relating to the Obligations, and if Secured Party has no further obligation to advance any amounts to Debtor, then all of the Collateral shall revert to Debtor, the liens and security interests created by this Instrument shall terminate and Secured Party shall, promptly after the request of Debtor or as otherwise required by applicable law, execute, acknowledge and deliver to Debtor a release or reconveyance of this Instrument and such other instruments as may be necessary to evidence the termination of the liens and security interests created by this Instrument.

Section 4.2 Partial Release. No partial release or reconveyance from the liens and security interests created by this Instrument of any part of the Collateral by Secured Party shall in any way alter, vary or diminish the force or effect of this Instrument or impair, release or subordinate the liens and security interests created by this Instrument on the remainder of the Collateral.

Except as specifically provided in any such partial release or reconveyance (i) this Instrument and liens and security interests created hereby shall remain in full force and effect, (ii) such partial release or reconveyance will not modify or affect the terms, conditions or provisions of this Instrument, and (iii) nothing contained in any such partial release or reconveyance shall be deemed to be, or construed as, a waiver of any such terms, conditions or provisions or as a waiver of any other term, condition or provision. All releases and reconveyances executed in connection with this Instrument shall be without warranty of any kind, express, implied or statutory.

Section 4.3 Costs, Expenses and Effect. Debtor shall pay all legal fees and other fees, costs and expenses incurred by Secured Party for preparing and reviewing instruments of termination and release or reconveyance and the execution and delivery thereof and Secured Party may require payment of the same prior to delivery of such instruments. The release and reconveyance of this Instrument and the termination of the liens and security interests created by this Instrument, in whole or in part, shall not terminate or otherwise affect Secured Party’s right or ability to exercise any right, power or remedy relating to any claim for breach of warranty or representation, for failure to perform any covenant or other agreement, under any indemnity or for fraud, deceit or other misrepresentation or omission.

ARTICLE V

Default

Section 5.1 Events of Default. The occurrence of any of the following events shall constitute an event of default (“Event of Default”) and upon the occurrence thereof the liens and security interests created hereby shall be subject to foreclosure in any manner provided for herein or provided for by applicable law:

A. Failure of Debtor to pay any fee or other amount due Secured Party under this Instrument within 10 days after the date that any such payment is due;

B. Failure of Debtor to perform or observe any covenant, agreement, indemnity, condition or provision in this Instrument and such failure shall continue for 30 days after the earlier to occur of (1) Debtor becoming aware of such failure, and (2) written notice of such failure has been given to Debtor;

C. Any of Debtor’s representations or warranties made in this Instrument or any statement or certificate at any time given in writing pursuant hereto or in connection herewith shall be false or misleading in any material respect as of the date made or deemed made; or

D. An “Event of Default” as defined in the Credit Agreement shall occur.

Section 5.2 Treatment of Fixtures. If an Event of Default shall have occurred and be continuing, if deemed appropriate by Secured Party or if required by applicable law, Secured Party may elect to treat the fixtures included in the Collateral either as real property or as personal property, or both, and proceed to exercise such rights as apply to the type of property selected.

Section 5.3 Acceleration and Foreclosure. If an Event of Default shall have occurred and be continuing, in addition to any other rights, powers and remedies herein conferred or conferred by operation of law, (a) Secured Party shall have all of the rights, powers and remedies of a creditor, secured party and mortgagee, (b) Secured Party may, without notice, demand or declaration of default, which are hereby waived by Debtor to the extent such waiver is not prohibited by applicable law, declare all indebtedness secured hereby due and payable, and (c) whether or not Secured Party exercises such option, it may, at its option and in its sole discretion, without any prior notice to or demand upon Debtor, proceed by one or more actions in equity or at law for the seizure and sale of the Collateral or any portion thereof, for the foreclosure or sale of the Collateral or any portion thereof by judicial foreclosure by appropriate proceedings in any court of competent jurisdiction or in any other manner then permitted by law, for the specific performance of any covenant or agreement of Debtor herein contained or in aid of the execution of any right, power or remedy herein granted, or for the enforcement of any other appropriate equitable or legal remedy and to recover judgment against Debtor. In furtherance, and not in limitation, thereof:

A. Mortgage. This Instrument shall constitute a mortgage under applicable law, and if an Event of Default shall have occurred and be continuing, may be foreclosed as to any of the Collateral by judicial action or in any manner then permitted by applicable law.

B. Additional Actions. This Instrument shall also constitute and may be enforced from time to time as an assignment, chattel mortgage, contract, mortgage, financing statement and security agreement, and from time to time as any one or more thereof as appropriate under applicable law. Secured Party shall be entitled to all of the rights, remedies and benefits of a secured party, mortgagee and a beneficiary granted under applicable law; and, to the fullest extent of such law, shall be entitled to enforce such rights, remedies and benefits. Debtor intends and hereby grants to Secured Party all rights, powers and remedies accorded a secured party, mortgagee and a beneficiary under applicable law whether or not such rights, powers and remedies are expressly granted or reserved herein.

C. Notice, Place and Manner of Sale. Any sale of the Collateral under this Article V shall take place at such place or places and otherwise in such manner and upon such notice as may be required by law; or, in the absence of any such requirement, as Secured Party may deem appropriate. Debtor expressly agrees that, except as may be required by applicable law, Secured Party may offer the Collateral as a whole or in such parcels or lots as Secured Party elects, regardless of the manner in which the Collateral may be described.

D. Postponement of Sale. Any sale of the Collateral conducted under this Article V may be postponed from time to time as provided by applicable law; or, in the absence of any such provisions, Secured Party may postpone the sale of the Collateral or any part thereof by public announcement at the time and place of such sale,

and from time to time thereafter may further postpone such sale by public announcement made at the time of sale fixed by the preceding postponement. Sale of a part of the Collateral will not exhaust the power of sale, and sales may be made from time to time until all Collateral is sold or the Obligations are paid in full.

E. Secured Party’s Right to Purchase. Secured Party shall have the right to bid or to become the purchaser at any sale made pursuant to the provisions of this Article V, and shall have the right to credit upon the amount of the bid made therefor the amount payable to it out of the net proceeds of such sale.

F. Conveyance to Purchaser. Any deed, xxxx of sale or other conveyance executed by or on behalf of Secured Party, the sheriff or other official or party responsible for conducting the sale shall be prima facie evidence of the compliance with all statutory requirements for the sale and execution of such deed, xxxx of sale or other conveyance and will conclusively establish the truth and accuracy of the recitals and other matters stated therein, including nonpayment or nonperformance of the Obligations, violation of the terms and covenants contained herein, and the advertisement and conduct of such sale in the manner provided herein or as provided by applicable law. Debtor, to the extent not prohibited by applicable law, does hereby ratify and confirm all legal acts that Secured Party may do in carrying out the provisions of this Instrument. Any sale of the Collateral or any portion thereof pursuant to the provisions of this Article V will operate to divest all right, title, interest, claim and demand of Debtor in and to the property sold and will be a perpetual bar against Debtor and shall, subject to applicable law, vest title in the purchaser free and clear of all liens, security interests and encumbrances, including liens, security interests and encumbrances junior or subordinate to the liens, security interests and encumbrances created by this Instrument. Upon any sale of the Collateral or any portion thereof pursuant to the provisions of this Article V, the receipt by Secured Party, the sheriff or other official or party responsible for conducting the sale, shall be sufficient discharge to the purchaser or purchasers at any sale for the purchase money, and such purchaser or purchasers and the heirs, devisees, personal representatives, successors and assigns thereof shall not, after paying such purchase money and receiving such receipt of Secured Party, the sheriff or such other official or party, be obliged to see to the application thereof or be in anywise answerable for any loss, misapplication or nonapplication thereof. Any purchaser at a sale will, subject to mandatory redemption periods, if any, receive immediate possession of the Collateral purchased, and Debtor agrees that if Debtor retains possession of the Collateral or any part thereof subsequent to such sale, Debtor will be considered a tenant at sufferance of the purchaser, and will, if Debtor remains in possession after demand to remove, be guilty of forcible detainer, and will be subject to eviction and removal, forcible or otherwise, with or without process of law and all damages to Debtor by reason thereof are hereby expressly waived by Debtor.

G. Federal Transfers. Upon a sale conducted pursuant to this Article V of all or any portion of the Collateral consisting of interests (the “Federal Interests”) in leases, easements, rights-of-way, agreements or other documents and instruments covering, affecting or otherwise relating to federal lands (including leases, easements and rights-of-way issued by the Bureau of Land Management); Debtor agrees to take all action and execute all instruments necessary or advisable to transfer the Federal Interests to the purchaser at such sale, including to execute,

acknowledge and deliver assignments of the Federal Interests on officially approved forms in sufficient counterparts to satisfy applicable statutory and regulatory requirements, to seek and request approval thereof and to take all other action necessary or advisable in connection therewith. By separate instruments, Debtor has irrevocably appointed, and by this Instrument hereby irrevocably appoints, Secured Party as Debtor’s attorney-in-fact and proxy, with full power and authority in the place and xxxxx of Debtor, in the name of Debtor or otherwise, to take any such action and to execute any such instruments on behalf of Debtor that Secured Party may deem necessary or advisable to so transfer the Federal Interests, including the power and authority to execute, acknowledge and deliver such assignments, to seek and request approval thereof and to take all other action deemed necessary or advisable by Secured Party in connection therewith; and Debtor hereby adopts, ratifies and confirms all such actions and instruments. By separate instruments Debtor has also irrevocably appointed Secured Party as Debtor’s attorney-in-fact and proxy, with full power and authority in the place and xxxxx of Debtor, in the name of Debtor or otherwise, to take any such action and to execute any such instruments on behalf of Debtor that Secured Party may deem necessary or advisable to so transfer the Federal Interests, including the power and authority to execute, acknowledge and deliver such assignments, to seek and request approval thereof and to take all other action deemed necessary or advisable by Secured Party in connection therewith; and by such separate instruments Debtor has adopted, ratified and confirmed all such actions and instruments. Such powers of attorney and proxies are coupled with an interest, shall survive the dissolution, termination, reorganization or other incapacity of Debtor and shall be irrevocable. No action taken by Secured Party shall constitute acknowledgment of, or assumption of liabilities relating to, the Federal Interests, and neither Debtor nor any other party may claim that Secured Party is bound, directly or indirectly, by any such action.

Section 5.4 Personal Property. If an Event of Default shall have occurred and be continuing, in addition to all other rights, powers and remedies herein conferred or conferred by operation of law, Secured Party shall have all of the rights and remedies of an assignee and secured party granted by applicable law, including the applicable Uniform Commercial Code as then in effect, and shall, to the extent permitted by applicable law, have the right and power, but not the obligation, to take possession of the personal property included in the Collateral and any proceeds thereof wherever located, and for that purpose Secured Party may enter upon any premises on which any or all of such personal property is located and take possession of and operate such personal property or remove the same therefrom. Secured Party may require Debtor to assemble such personal property and make it available to Secured Party at a place to be designated by Secured Party that is reasonably convenient to both parties. The following presumptions shall exist and shall be deemed conclusive with regard to the exercise by Secured Party of any of its remedies with respect to personal property:

A. If notice is required by applicable law, Debtor agrees that five days’ prior written notice of the time and place of any public sale or of the time after which any private sale or any other intended disposition thereof is to be made shall be deemed reasonable notice to Debtor. No such notice is necessary if such property is perishable, threatens to decline speedily in value or is of a type customarily sold on a recognized market.

B. If Secured Party in good faith believes that the Securities Act of 1933 or any other state or federal law prohibits or restricts the customary manner of sale or distribution of any of such property, Secured Party may sell such property privately or in any other manner deemed advisable by Secured Party at such price or prices as Secured Party determines in its sole discretion. Debtor recognizes that such prohibition or restriction may cause such property to have less value than it otherwise would have and that, consequently, such sale or disposition by Secured Party may result in a lower sales price than if the sale were otherwise held.

Section 5.5 Possession. If an Event of Default shall have occurred and be continuing, in addition to all other rights, powers and remedies herein conferred or conferred by operation of law, Secured Party shall, to the extent not prohibited by applicable law, have the right and power, but not the obligation, to enter upon and take immediate possession of the Collateral or any portion thereof, to exclude Debtor therefrom, to hold, use, operate, manage, enjoy and control such Collateral, to make all such repairs, replacements, alterations, additions and improvements to the same as Secured Party may deem proper or expedient, to sell all of the severed and extracted Hydrocarbons included in the same subject to the provisions of Article III hereof, to demand, collect and retain all other earnings, rents, issues, profits, proceeds and other sums due or to become due with respect to such Collateral accounting for and applying to the payment of the Obligations only the net earnings arising therefrom after charging against the receipts therefrom all fees, costs, expenses, charges, damages and losses incurred by reason thereof plus interest thereon at the Default Rate without any liability to Debtor in connection therewith. Such possession shall at once be delivered to Secured Party upon request, and on refusal or failure to so deliver possession, the delivery of such possession may be enforced by Secured Party by any appropriate civil suit, proceeding or other action.

Section 5.6 Appointment of Receiver. If an Event of Default shall have occurred and be continuing, in addition to all other rights, powers and remedies herein conferred or conferred by operation of law, Secured Party shall be entitled to the appointment of a receiver of the Collateral without the necessity of the posting of a bond or notice; and shall, to the extent not prohibited by applicable law, be entitled to such receiver as a matter of right, without regard to the solvency or insolvency of Debtor, the value or adequacy of the Collateral or the Collateral being in danger of being materially injured or reduced in value as security by removal, destruction, deterioration, accumulation of prior liens or otherwise; and such receiver may be appointed by any court of competent jurisdiction upon ex parte application, and without notice, notice being expressly waived by Debtor to the extent such waiver is not prohibited by applicable law. Debtor does hereby consent to the appointment of such receiver or receivers, waives any and all defenses to such appointment, and agrees not to oppose any application therefor by Secured Party, and agrees that such appointment shall in no manner impair, prejudice or otherwise affect the rights of Secured Party under this Article V. Nothing herein is to be construed to deprive Secured Party of any other right, remedy or privilege it may now or hereafter have under law to have a receiver appointed. Any money advanced by Secured Party in connection with any such receivership shall be a demand obligation owing by Debtor to Secured Party and shall bear interest, from the date of making such advancement until paid, at the Default Rate.

Any such receiver shall have all powers conferred by the court appointing such receiver, which powers shall, to the extent not prohibited by applicable law include, without limitation, the right to enter upon and take immediate possession of the Collateral or any part thereof, to exclude Debtor therefrom, to hold, use, operate, manage and control such Collateral, to make all such repairs, replacements, alterations, additions and improvements to the same as such receiver or Secured Party may deem proper or expedient, to lease, sell or otherwise transfer the Collateral or any portion thereof as such receiver or Secured Party may deem proper or expedient, to sell all of the Hydrocarbons included in the same subject to the provisions of Article III hereof, to demand and collect all of the other earnings, rents, issues, profits, proceeds and other sums due or to become due with respect to such Collateral, accounting for only the net earnings arising therefrom after charging against the receipts therefrom all fees, costs, expenses, charges, damages and losses incurred by reason thereof plus interest thereon at the Default Rate without any liability to Debtor in connection therewith which net earnings shall be turned over by such receiver to Secured Party to be applied by Secured Party to the payment of the Obligations in the order set forth in Section 5.10.

Section 5.7 Waiver by Debtor. To the extent not prohibited by applicable law, Debtor agrees that Debtor shall not at any time have, invoke, utilize or assert any right under any laws pertaining to the marshaling of assets or liens, the sale of property in the inverse order of alienation, the exemption of homesteads, the administration of estates of decedents, appraisement, moratorium, valuation, stay, extension or redemption now or hereafter in force, and Debtor hereby waives the benefit of all such laws to the fullest extent not prohibited by applicable law.

Section 5.8 Remedies Cumulative. All rights, powers and remedies herein conferred are cumulative, and not exclusive, of (a) any and all other rights and remedies herein conferred, (b) any and all rights, powers and remedies existing at law or in equity, and (c) any and all other rights, powers and remedies provided for in any other documents or instruments evidencing, securing or relating to the Obligations, and Secured Party shall, in addition to the rights, powers and remedies herein conferred, be entitled to avail itself of all such other rights, powers and remedies as may now or hereafter exist at law or in equity for the collection of and enforcement of the Obligations and the enforcement of the warranties, representations, covenants, indemnities and other agreements contained in this Instrument and the other documents and instruments evidencing, securing or relating to the Obligations and the foreclosure of the liens and security interests created by this Instrument. Each and every such right, power and remedy may be exercised from time to time and as often and in such order as may be deemed expedient by Secured Party and the exercise of any such right, power or remedy shall not be deemed a waiver of the right to exercise, at the same time or thereafter, any other right, power or remedy. No delay or omission by Secured Party, the sheriff or other official or person in the exercise of any right, power or remedy will impair any such right, power or remedy or operate as a waiver thereof or of any other right, power or remedy then or thereafter existing.

Section 5.9 Costs and Expenses. All fees, costs and expenses (including reasonable attorneys’ fees and legal expenses, court costs, filing fees, and mortgage, transfer, stamp and other excise taxes, inspection fees, appraisers’ fees, outlays for documentary and expert evidence, stenographers’ charges, publication, notice and advertising costs, postage, photocopies, telephone charges and costs of procuring all abstracts of title, title searches and examinations,

D. Fourth, to the payment or prepayment of the Obligations other than the Obligations evidenced by the Note in such order as Secured Party may elect; and

Debtor hereby waives the right to assert any statute of limitations as a defense to the Obligations (including the indebtedness, liabilities and obligations under and pursuant to this Instrument, the Note, the Credit Agreement and any other instrument evidencing, securing or otherwise relating to the Obligations), to the fullest extent not prohibited by applicable law.

Section 5.12 Limitation on Rights and Waivers. All rights, powers and remedies herein conferred shall be exercisable by Secured Party only to the extent not prohibited by applicable law; and all waivers and relinquishments of rights and similar matters shall only be effective to the extent such waivers or relinquishments are not prohibited by applicable law.
