SUCH LENDER’S DEMAND WILL STATE WITH SPECIFICITY THE BASIS FOR THE TAX, IDENTIFY THE TAXING AUTHORITY ASSERTING THE TAX AND CERTIFY THAT LENDER HAS PAID THE TAX.

None of the other reports, financial statements, certificates or other information furnished by or on behalf of Borrower or any Affiliate to Lender or any of their Affiliates in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or under any other Loan Document (as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time.

17

Section 9.3.Set-Off Rights. Upon the occurrence and during the continuation of an Event of Default, Lender will have the right, at any time and from time to time, to set-off and apply against the Obligations, in any manner Lender may determine, any and all deposits (general or special, time or demand, provisional or final) or other amounts at any time credited by or owing from Lender or any depositary to Borrower whether or not the Obligations are then due; provided, however, that this sentence will not apply to any amounts owing to third-party Working Interest and Royalty Interest previously identified in writing to Lender.

To the extent Lender assigns to any other Person an interest in the Term Note, Borrower shall execute and deliver to Lender any documents reasonably necessary in connection with such transaction, including the issuance by Borrower of one or more Term Notes. Additionally, so long as Borrower’s rights and obligations hereunder are not adversely affected, Lender will be entitled to grant and assign a security interest in its rights, titles, and interests in and to the Term Note, the Security Documents and all other Loan Documents to its lender or lenders as security for indebtedness of the Lender.

Neither party or any of their respective Affiliates will issue any press release or make any other public announcement relating to this Agreement without the prior written consent of the other party; provided, however, Lender and Borrower may each publish a “tombstone” announcement regarding this Agreement.

Section 10.6.Final Agreement.

(a)Fees, Costs and Expenses. Borrower will promptly pay (within thirty (30) days after receipt of invoice or other statement or notice) (i) all transfer, stamp, mortgage, documentary or other similar taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on behalf of Lender (including attorneys’ fees, consultants’ fees and engineering fees, travel costs and miscellaneous expenses) in connection with (A) the negotiation, preparation, execution and delivery of any and all consents, waivers and amendments to any of the Loan Documents, (B) the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled or re-recorded by the terms of any Loan Document, (C) the borrowings hereunder and other action reasonably required in the course of administration hereof, and (D) monitoring or confirming (or preparation or negotiation of any documents related to) Borrower’s compliance with any covenants or conditions contained in this Agreement or in any other Loan Document, and (iii) all reasonable costs and expenses incurred by or on behalf of Lender (including attorneys’ fees, consultants’ fees and accounting fees) in connection with the defense or enforcement of any of the Loan Documents (including this section) or the defense of Lender’s exercise of its rights thereunder. In addition, except as otherwise provided herein, until all Obligations are paid in full, Borrower shall also pay or reimburse Lender for all reasonable out-of-pocket costs and expenses of Lender or its agents or employees in connection with the continuing administration of the Term Loan and the related due diligence of Lender, including travel and miscellaneous expenses and fees and expenses of Lender’s outside counsel, reserve engineers and consultants engaged in connection with the Loan Documents.

(b)Indemnification. BORROWER AGREES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW TO DEFEND, RELEASE AND INDEMNIFY LENDER, UPON DEMAND, FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, CLAIMS, LOSSES, DAMAGES, PENALTIES, FINES, ACTIONS, JUDGMENTS, SUITS, SETTLEMENTS, COSTS, EXPENSES OR DISBURSEMENTS (INCLUDING REASONABLE FEES OF ATTORNEYS, ACCOUNTANTS, EXPERTS AND ADVISORS) OF ANY KIND OR NATURE WHATSOEVER (IN THIS SECTION, COLLECTIVELY CALLED “LIABILITIES AND COSTS”) WHICH TO ANY EXTENT (IN WHOLE OR IN PART) MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST LENDER ARISING OUT OF, RESULTING FROM OR IN ANY OTHER WAY ASSOCIATED WITH ANY OF THE COLLATERAL, THE LOAN DOCUMENTS AND THE TRANSACTIONS AND EVENTS (INCLUDING THE ENFORCEMENT OR DEFENSE THEREOF) AT ANY TIME ASSOCIATED THEREWITH OR CONTEMPLATED THEREIN (INCLUDING ANY VIOLATION OR NONCOMPLIANCE WITH ANY ENVIRONMENTAL LAWS BY ANY RESTRICTED PERSON OR ANY LIABILITIES OR DUTIES OF ANY RESTRICTED PERSON OR LENDER WITH RESPECT TO HAZARDOUS MATERIALS FOUND IN OR RELEASED INTO THE ENVIRONMENT).

21

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY LENDER, PROVIDED ONLY THAT LENDER SHALL NOT BE ENTITLED UNDER THIS SECTION TO RECEIVE INDEMNIFICATION FOR THAT PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS PROXIMATELY CAUSED BY ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL JUDGMENT. IF ANY PERSON (INCLUDING BORROWER OR ANY OF ITS AFFILIATES) EVER ALLEGES SUCH GROSS NEGLIGENCE OR WILLFUL MISCONDUCT BY LENDER, THE INDEMNIFICATION PROVIDED FOR IN THIS SECTION SHALL NONETHELESS BE PAID UPON DEMAND, SUBJECT TO LATER ADJUSTMENT OR REIMBURSEMENT, UNTIL SUCH TIME AS A COURT OF COMPETENT JURISDICTION ENTERS A FINAL JUDGMENT AS TO THE EXTENT AND EFFECT OF THE ALLEGED GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. AS USED IN THIS SECTION THE TERM “LENDER” SHALL REFER NOT ONLY TO THE PERSONS DESIGNATED AS SUCH IN SECTION 1.1 BUT ALSO TO EACH DIRECTOR, OFFICER, AGENT, ATTORNEY, EMPLOYEE, REPRESENTATIVE AND AFFILIATE OF SUCH PERSONS.

Section 10.11.Compliance with Law. It is the intention of the parties to comply with applicable usury laws (now or later enacted). Accordingly, and notwithstanding any provision to the contrary in this Agreement, the other Security Documents or any other Loan Document, in no event will this Agreement or any other Loan Document require the payment or permit the collection of interest in excess of the maximum amount permitted by those laws. If, under any circumstances, the fulfillment of any provision of this Agreement or of any other Loan Document will involve exceeding the limit prescribed by applicable law for the contracting for or charging or collecting interest, then the obligation to be fulfilled will, ipso facto, be reduced to the allowable limit, and if, under any circumstances, Lender ever receives pursuant to any of the Loan Documents anything of value as interest or that is deemed to be interest under applicable law that would exceed the highest lawful rate, the amount that would otherwise be excessive interest will be applied to the reduction of the principal amount owing under the Term Note or on account of any other indebtedness owed by Borrower to Lender, and not to the payment of interest; or, if any portion of the excessive interest exceeds the unpaid balance of principal of that indebtedness, then the excess amount will be refunded to Borrower. In determining whether or not the interest paid or payable with respect to any indebtedness owed by Borrower to Lender exceeds the highest lawful rate, Borrower and Lender will, to the maximum extent permitted by applicable law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects of them, (c) amortize, prorate, allocate and spread the total amount of interest throughout the full term of the indebtedness so that the actual rate of interest on account of the indebtedness does not exceed the maximum amount permitted by applicable law, and (d) allocate interest between portions of the indebtedness so that no portion will bear interest at a rate greater than that permitted by applicable law.

22

Section 10.12.Power of Attorney; Etc. Borrower grants to Lender a power of attorney for the purpose of executing on behalf of Borrower documents related to the enforcement of Lender’s rights under the Security Documents, including but not limited to the execution of any instrument to be filed with or approved by any applicable state regulatory agency in the event of a foreclosure on any of the Property. The power of attorney granted to Lender by Borrower under this Section 10.12 is a right coupled with an interest and will be irrevocable for as long as any of the Obligations remain outstanding provided, however that Lender agrees not to exercise the power of attorney described in this Section 10.12 prior to the occurrence of an Event of Default.

Section 10.13.Payment of Borrower Debt. Lender may, at its sole option, but without any obligation, pay on behalf of Borrower any Debt of Borrower giving rise to Liens which have priority ahead of the Liens of Lender in and to the Collateral or any part thereof and any amounts so paid by Lender shall become a part of the Obligations considered an Advance on the Term Note hereunder and shall accrue interest at the Contract Rate or Default Rate, as applicable.

Section 10.14.Severability. Any section, clause, subsection, sentence, paragraph, provision or term this Agreement held invalid, illegal, or ineffective by a court of competent jurisdiction will not impair, invalidate or nullify the remainder of this Agreement.

Section 10.15.Captions; Headings. The headings, captions and arrangements contained in this Agreement have been inserted for convenience only and will not be deemed in any manner to modify, explain, enlarge or restrict any provision in this Agreement.

Section 10.16.Construction. Borrower and Lender acknowledge that each of them has had the benefit of legal counsel of its own choice and has been afforded an opportunity to review this Agreement, the Term Note and each of the other Loan Documents with its legal counsel and that this Agreement and the other Security Documents will be construed as if jointly drafted by Borrower and Lender. In the event of a conflict between the terms of this Agreement and the Security Documents, the terms of this Agreement shall be controlling.
