Borrower acknowledges that Lender does not intend to advance Borrower any amount which would at any point in time exceed the Maximum Commitment; provided, however, if the obligations of Borrower under the Term Loan exceed the Maximum Commitment, all obligations will nevertheless constitute Obligations under this Agreement, become a part of the Term Loan and be entitled to the benefit of all of Lender’s security interests in, and mortgage liens on, the Collateral.

Section 2.2. Term Note. Borrower’s obligation to repay the Term Loan will be evidenced by a Term Note in favor of Lender. The Term Note will be dated as of and delivered to Lender on the Closing Date.

Section 2.3. Interest.

(a) Outstanding borrowed and unpaid principal amounts of the Term Loan shall bear interest at the Contract Rate for the period commencing on the date of each Advance until all Obligations are paid in full in accordance with this Agreement. Upon the occurrence and during the continuation of an Event of Default, the rate of interest applicable to the Obligation will be equal to the lesser of (i) the Highest Lawful Rate and (ii) four percent (4.0%) over the Contract Rate (the “Default Rate”). In addition, if any principal of or interest on any Advance or any fee or other amount payable by Borrower or any other obligor hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to the Default Rate.

(b) All interest will be computed on the actual number of days elapsed over a year comprised of 360 days. Interest will be due and payable in immediately available funds on the Maturity Date.

(c) The applicable interest rate shall be determined by Lender, and its determination shall be conclusive absent manifest error and binding upon the parties hereto.

Section 2.4. Outstanding Payments.

(a) All outstanding principal and accrued interest shall be due and payable as provided in the Development and Exploration Agreement, and in no event later than the Maturity Date. All payments shall be applied first to accrued interests and the balance to outstanding principal.

▇▇▇ ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

or to any other account Lender may designate in writing to Borrower from time to time. If any payment to be made under this Agreement falls due on a day that is not a Business Day, the payment will be payable on the next succeeding Business Day.

Section 2.5. Taxes.

(a) Taxes Not Deducted from Payments to Lender. All payments made by Borrower under this Agreement will be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all similar liabilities excluding, in the case of Lender, taxes imposed on its income, and franchise or similar taxes imposed on it, by any jurisdiction (or political subdivision thereof) of which Lender is a citizen or resident, in which Lender is organized, or in which Lender is presently doing business (collectively, “Taxes”). If Borrower is required by law to deduct any Taxes from any sum payable to Lender, (i) the sum payable will be increased by an amount so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.5) Lender will receive an amount equal to the sum it would have received had no deductions been made, (ii) Borrower will deduct from the sum payable to Lender an amount sufficient to pay the Taxes and pay the balance to Lender, and (iii) Borrower will promptly pay the full amount deducted to the relevant Taxing Authority or other Governmental Authority in accordance with applicable law.

(b) Other Taxes. In addition, and to the fullest extent permitted by applicable law, Borrower agrees to pay any present or future stamp, documentary, mortgage registration, or similar taxes or any other excise or property taxes, charges or similar levies that arise from any payment made or from the execution, delivery, or registration of, or otherwise with respect to, this Agreement, or any Security Documents (collectively, the “Other Taxes”).

(c) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, AND PROVIDED THAT THERE IS NO DEFAULT OF THE LENDER REPRESENTATIONS CONTAINED IN THIS AGREEMENT, BORROWER WILL INDEMNIFY LENDER FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 2.5 AND PAID BY LENDER) PAID BY LENDER (ON BEHALF OF BORROWER), AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND REASONABLE EXPENSES) ARISING FROM OR WITH RESPECT TO THOSE AMOUNTS, WHETHER OR NOT THE TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED. ANY PAYMENT PURSUANT TO THE INDEMNIFICATION DESCRIBED IN THIS SECTION 2.5(c) WILL BE MADE BY BORROWER WITHIN THIRTY (30) DAYS AFTER THE DATE LENDER MAKES WRITTEN DEMAND FOR THOSE PAYMENTS. 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.

(d) Certification of Tax Status By Lender. Lender agrees that it will, not more than thirty (30) Business Days after the date of this Agreement, deliver to Borrower a United States Internal Revenue Service Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax.

ARTICLE III

(a) Mortgage and Security Interest. As collateral security for all of its Obligations to Lender under this Agreement and the other Loan Documents, Borrower shall and hereby grants, assigns, transfers and conveys to Lender a mortgage lien on and perfected security interest in the Collateral.

(b) Further Assurances. Borrower will, upon request, execute and deliver to Lender any and all documents necessary or desirable, in the reasonable opinion of Lender, to create, perfect, maintain, and preserve the priority of Lender’s security interests in and mortgage liens on the Collateral.

Borrower irrevocably authorizes Lender to prepare and file at any time and from time to time in any filing office initial financings statements and amendments to them necessary or convenient to the perfection or continuation of the security interests granted by Borrower.

(c) Release of Financing Statements. Upon the indefeasible payment in cash and performance in full of all Obligations under this Agreement (other than indemnity obligations and similar obligations that survive the termination of this Agreement), Lender will deliver to Borrower, at Borrower’s expense, releases of all financing statements and all other Security Documents with an acknowledgment that the same have been terminated, and Borrower shall deliver to Lender a general release of all of Lender’s liabilities and obligations under this Agreement and the other Loan Documents. The obligations of Borrower under the Assignment and ▇▇▇▇ of Sale will survive the termination of this Agreement and the release of the security interests.

ARTICLE IV

Representations and Warranties

In order to induce Lender to make the Term Loan, Borrower makes the following representations and warranties to Lender as of the Closing Date, each and all of which will survive the execution and delivery of this Agreement and continue until all Obligations (other than indemnity obligations and similar obligations that survive the termination of this Agreement) have been satisfied and Lender has no further commitment to make Advances under this Agreement.

Borrowers are qualified to do business in every other jurisdiction where the nature of its business or the ownership of its property requires it to be so qualified and where failure to so qualify could reasonably be expected to have a Material Adverse Effect.

Section 4.2. Ownership of Collateral; Interests. All Collateral is owned of record by Borrower and the Working Interests will be conveyed to Lender or its designee by Borrower, free and clear of any security interest, lien, encumbrance, mortgages, security agreement or other charge. Borrower has Defensible Title to the Properties, including each Lease related to the Properties. Except for the liens and security interests contemplated by this Agreement and the Security Documents, to Borrower’s knowledge there are no unrecorded documents or agreements which may result in the impairment or loss of Borrower’s ability to mortgage the Properties or of Lender’s ability to enforce the Mortgage and convey the Properties. Borrower has all beneficial rights, titles and interests in and to the Net Revenue Interest in all production from or allocable to Borrower’s interest in the Properties (including each Lease) and has the exclusive right to sell or mortgage the Properties subject to any right in the owners of Royalty Interests to take their royalty interest in kind.

Section 4.3. Leases, etc. All leases and agreements referenced in the reports or other title materials delivered in connection with the Closing are valid and subsisting, in full force and effect and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would adversely affect in any material respect the conduct of the business of Borrower. All of the assets of Borrower which are reasonably necessary for the operation of its business are in good working condition (ordinary wear and tear excepted) and are maintained in accordance with prudent business standards.

Section 4.4. Authorization; Non-Contravention. The execution, delivery and performance of Borrower’s obligations under this Agreement, the Term Note, the Assignment and ▇▇▇▇ of Sale, the Security Documents and all and any other Loan Documents and the creation of all liens, mortgages and security interests provided for in those agreements:

(a) are within the corporate power and authority of Borrower;

(b) have been duly authorized by all necessary company action of Borrower;

(c) are not in contravention of (i) any agreement or indenture to which Borrower is a party or by which it or its property is bound, (ii) the charter documents of Borrower, or (iii) to Borrower’s knowledge any provision of law applicable to Borrower;

(d) do not require the consent or approval of any governmental body, agency, authority or any other Person which has not been obtained and a correct and complete copy of each of those approvals has been furnished to Lender; and

(e) are legal, valid, and binding obligations of Borrower, enforceable against Borrower in accordance with their respective terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors rights generally and by general equitable principles.

Section 4.5. Solvency. Borrower is Solvent and will continue to be Solvent after giving effect to the transactions contemplated by this Agreement.

Section 4.6. Omissions and Misstatements. Borrower has disclosed to Lender all agreements, instruments and corporate or other restrictions to which it is subject, and all other matters known to it, that, individually or in the aggregate, would reasonably be expected to result in a Material Adverse Effect. 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. There is no fact peculiar to Borrower or any Affiliate which would reasonably be expected to have a Material Adverse Effect or in the future would be likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan Documents or the other documents, certificates and statements furnished to Lender by or on behalf of Borrower or any Affiliate prior to, or on, the date hereof in connection with the transactions contemplated hereby. There are no statements or conclusions in any reserve report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein.

Section 4.7. USA Patriot Act Representation. Neither Borrower nor any of its Affiliates is a country, individual or entity named on the Specifically Designated National and Blocked Persons list issued by the Office of Foreign Asset Control of the Department of the Treasury of the United States of America.

Upon the occurrence of an Event of Default described in Section 8.1(c) or Section 8.1(d), the commitments to make additional Advances shall automatically terminate and the Term Note and the principal of the Term Loan then outstanding, together with accrued interest thereon and all fees and the other obligations of Borrower accrued hereunder and under the Notes and the other Loan Documents, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by Borrower. Upon a termination of its commitments following an Event of Default, Lender will have, in addition to all of its other rights arising under any of the Loan Documents or by operation of law or otherwise (which rights shall be cumulative), all of the rights and remedies of a secured party under the Uniform Commercial Code and will have the right to enter upon any premises where the Collateral is kept and peacefully retake possession.

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.

Lender may assign, transfer or otherwise dispose of any of its rights or obligations under this Agreement or any of the other Loan Documents on the prior written consent of Borrower, such consent to not be unreasonably withheld. 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.

Section 10.3. Notices. Any notice, demand or document which either party is required or may desire to give to the other will be in writing and, except as otherwise provided in this Agreement, given by messenger, nationally recognized courier, overnight delivery, facsimile or other electronic transmission, or United States certified mail, postage prepaid, return receipt requested, addressed to the recipient at the location shown below, or at any other address as either party may furnish to the other by notice given in accordance with this provision.

If to any other obligor party, the notice will be sent to the Borrower and to the address set forth in the Security Document or other Loan Document to which the recipient is a party.

Any notice delivered or made by messenger, telecopy, electronic mail or United States mail will be deemed to be given on the date of actual delivery as shown by messenger receipt, the sender’s facsimile machine confirmation or other verifiable electronic receipt, or the registry or certification receipt. Notwithstanding the previous sentence, if either party receives from the other any message via electronic mail that purports to be a notice under this Agreement but that contains information that is syntactically incorrect, garbled or otherwise unintelligible, the recipient will notify the sender and the message containing the unintelligible information will not be deemed to be given until it is successfully delivered (including redelivery by electronic mail) pursuant to this Section 10.3. If Lender receives oral notice of any event from an authorized officer of Borrower, Lender will not be required to delay the exercise of any rights arising from the occurrence of that event until it receives written confirmation of the oral notice. In the event that a discrepancy exists between the notice received by Lender orally and the written confirmation, or in the absence of a written confirmation, the oral notice, as understood by Lender will be deemed the controlling and proper notice.

Section 10.4. Waivers; Amendments. Neither the failure nor any delay on the part of any party to exercise any right, remedy, power, privilege or option under this Agreement will operate as a waiver of that or any other right, remedy, power, privilege or option. No single or partial exercise of any right, remedy, power, privilege or option under this Agreement will preclude any other or further exercise or the exercise of any other right, remedy, power, privilege or option. No waiver of any right, remedy, power, privilege or option with respect to any occurrence will be construed as a waiver of that right, remedy, power, privilege or option with respect to any subsequent or other occurrence.

Section 10.5. Confidentiality.

Notwithstanding the previous sentence, Lender may disclose the substantive terms of or furnish its lenders and potential lenders and investment bankers and their respective attorneys, accountants or engineers with copies of this Agreement or any Security Document or any other document agreement or instrument relating to or executed or delivered to Lender in conjunction with this Agreement without the consent of Borrower. 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. This Agreement and the other agreements to which this Agreement refers, together with all exhibits, schedules and annexes attached to any of them, constitute the final, entire agreement among the parties and supersede any prior oral or written and all contemporaneous oral proposals, commitments, promises, agreements and understandings between the parties with respect to the subject matter of this Agreement and the other Loan Documents, all of which are merged into and replaced by the Loan Documents.

Section 10.10. Fees, Costs and Expenses; Indemnification

(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).

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.

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.
