Capitalized terms used but not defined in this Amendment have the meaning given them in the Credit Agreement (defined below).  Background  A. Borrower and Lender have previously entered into an Amended and Restated Senior First Lien Secured Credit Agreement dated September 14, 2006 (as amended by the First Amendment to Credit Agreement dated November 7, 2006, the Second Amendment to Credit Agreement dated August 5, 2010, the Third Amendment to Credit Agreement dated October 19, 2010, and as otherwise amended, restated, modified or supplemented from time to time, the Credit Agreement), for the purpose of making available to Borrower a senior secured term loan for the purposes set forth in the Credit Agreement.  B. Borrower has requested Lender, among other things, to extend the Maturity Date of the Credit Agreement and to suspend monthly amortization payments from Borrower to Lender thereunder.  C. Radiant Oil & Gas, Inc. (Parent) proposes to issue convertible preferred Equity Interests (the Convertible Preferred Equity Raise) as set forth in the term sheet attached hereto as Exhibit A, on or before the Maturity Date (as defined in this Amendment).  D. Borrower and Lender desire to modify certain terms and conditions of the Credit Agreement.  E. Lender is willing to amend the Credit Agreement pursuant to the terms and conditions of this Amendment.  Agreements  In consideration of the mutual covenants of Borrower and Lender set forth in this Amendment and other good and valuable consideration, the receipt and sufficiency of which are acknowledged by each of the parties, Borrower and Lender agree as follows:  1. Definitions.  Article I of the Credit Agreement is amended as follows:  (a) The definition of Maturity Date is deleted in its entirety and replaced with the following:  Maturity Date means the earlier of (a) September 9, 2011, or (b) the first date on which the payment and performance of the Obligations are accelerated by Lender as a result of the occurrence of one or more Events of Default.  (b) The following definitions are added to Article I of the Credit Agreement in alphabetical order:  Fourth Amendment means the Fourth Amendment to Credit Agreement between Borrower, Lender and the other parties thereto dated effective as of March 20, 2011.  Parent means Radiant Oil & Gas, Inc.  2. Convertible Preferred Equity Raise.  Upon consummation of the Convertible Preferred Equity Raise by Parent in an aggregate amount of not less than five-million dollars ($5,000,000.00) on or before the Maturity Date, Borrower shall cause and Parent agrees to pay Lender an amount not less than $900,000 to be applied to the Obligations (including accrued interest), with any remaining amount to be applied to the Obligations (including accrued interest) under and as defined in the Amber Loan Documents.  In the event less than five-million dollars ($5,000,000.00) is raised under the Convertible Preferred Equity Raise, Borrower shall cause and Parent agrees to pay one-sixth (1/6) of the amount actually raised, to be applied as stated above.  For avoidance of doubt, notwithstanding any other provision in the Loan Documents or the Amber Loan Documents to the contrary and any payment in full of the Obligations under the Loan Documents, the Borrower and each other Obligor hereby agree that the Security Documents in support of the Loan Documents will remain in full force and effect to secure the Obligations under the Amber Loan Documents, until such Obligations have been paid in full.    3. Amortization Payments.  Borrower, each other Obligor and Lender agree that any and all minimum monthly amortization payments due and owing under Section 2.6(a) of the Credit Agreement will be suspended until the Maturity Date; provided, however, that, notwithstanding the foregoing, any and all equity funding received by Borrower or any of its Affiliates (other than the Preferred Convertible Equity Raise, which is otherwise addressed in Section 2 hereof) or any cash flow or insurance proceeds received by Borrower on or before the Maturity Date shall be paid to Lender in accordance with the terms, including without limitation, Section 2.10, of the Credit Agreement, as amended hereby, to be applied against the Obligations.  4. Limited Waiver of Defaults.  Lender hereby waives any Default or Event of Default existing under any of the Loan Documents immediately prior to the execution and delivery of this Amendment.  Notwithstanding the previous sentence, however, NOTHING IN THIS AMENDMENT WILL BE CONSTRUED TO CONSTITUTE A WAIVER BY LENDER OF ANY FUTURE DEFAULT OR EVENT OF DEFAULT BY BORROWER OR ANY OTHER PERSON UNDER THE CREDIT AGREEMENT (AS AMENDED HEREBY) OR ANY OF THE OTHER LOAN DOCUMENTS.  NOTHING HEREIN SHALL BE CONSTRUED TO WAIVE ANY RIGHTS OR REMEDIES AVAILABLE TO LENDER OR ITS AFFILIATES PURSUANT TO THE CREDIT AGREEMENT, OTHER LOAN DOCUMENTS, THE COMPANY AGREEMENT, OR BY OPERATION OF LAW OR OTHERWISE (WHICH RIGHTS SHALL BE CUMULATIVE) AS A RESULT OF ANY FUTURE DEFAULT OR EVENT OF DEFAULT.  5. Conversion of Debt.  Lender and Borrower agree that Lender shall convert an aggregate of One Million Dollars ($1,000,000) of the Obligations under the Amber Loan Documents to Equity Interests in Parent pursuant to definitive and mutually acceptable documentation and upon the satisfaction of the following conditions:  (i) Parent has paid (and Lender has received) an aggregate of Nine Hundred Thousand Dollars ($900,000) to Lender pursuant to Section 2 and/or Section 3 of this Amendment to be applied as set forth in Section 2, and (ii) no Event of Default exists.  Parent and Lender agree that the unit share price of the Equity Interests in Parent into which Lender will convert will be equal to the per share price of Parents most recent material equity raise from a Person who is not an Affiliate.  6. The Obligations.  Borrower and each of the other Obligors agree and acknowledge that, as of March 18, 2011, (a) the principal amount outstanding under the Term Note is Eight Hundred Eighteen Thousand Three Hundred Eight Dollars and Fifty-Two Cents ($818,308.52), (b) the amount of unpaid and accrued interest on the Term Note is Forty-Seven Thousand Two Hundred Forty-Four Dollars and Forty-Five Cents ($47,244.45), and (c) no defense or right of set off exists with respect to the enforceability of any of the Obligations.  7. Default Interest Rate.  For the avoidance of any doubt, notwithstanding Section 4 hereof and in accordance with the email dated September 17, 2009, pursuant to which Lender notified Borrower that a payment default exists and is continuing under the Credit Agreement, interest shall continue to accrue at the Default Rate and to the extent that interest due and payable is not satisfied by the cash flow sweep provisions of Section 2.8 of the Credit Agreement, interest shall, each month, be capitalized as principal and bear interest at the Default Rate until the Maturity Date set forth in this Amendment at which time all principal and accrued and unpaid interest shall be due and payable.  8. Breach of Agreements.  For avoidance of doubt, Borrowers or any other Obligors breach of the agreements set forth in Sections 2 and 3 of this Amendment shall constitute an Event of Default under Section 10.1 of the Credit Agreement, as amended hereby.  9. Conditions to Effectiveness of This Amendment .  This Amendment will become effective upon the execution and/or delivery to Lender of each of the following documents by the Parent or Borrower, as applicable, each in form and substance acceptable to Lender:  (a) Parent has delivered to Lender the Term Sheet for the Convertible Preferred Equity Raise, which shall be in form and substance satisfactory to Lender; and  (b) Borrower and the other parties to each of the following documents (other than Lender) have executed and delivered each of the following documents to Lender in form and substance acceptable to Lender:  (i) this Amendment;  (ii) Certificate of the Managing Member of Borrower certifying as to Borrowers and Managing Members Charter Documents, authorizing resolutions and good standing;  (iii) Certificate of Secretary of JOG certifying as to JOGs Charter Documents, authorizing resolutions and good standing;  2    (iv) Certificate of Secretary of Parent certifying as to Parents Charter Documents, authorizing resolutions and good standing; and  (v) any other document necessary or convenient in the opinion of Lender or its counsel to give effect to the modifications to the Credit Agreement contemplated by this Amendment.  10.

(b) This Amendment represents the legal, valid and binding obligations of Borrower and such other Obligor enforceable against them in accordance with its terms except as enforceability may be limited by applicable Debtor Relief Laws and by general equitable principles.  (c) A true and complete copy of the Term Sheet for the Convertible Preferred Equity Raise is attached as Exhibit A hereto.  11. Ratification of Liens and Security Interests.  Borrower and each other Obligor, as applicable, hereby acknowledge and ratify the existence and priority of the Liens granted by Borrower or such Obligor in favor of Lender in and to the Collateral and represent, warrant and covenant that such liens and security interests are valid, existing and in full force and effect.  12. Miscellaneous.  The Credit Agreement, as amended hereby, supersedes all prior agreements (written or oral) between Borrower and Lender with regard to the subject matters hereof.  This Amendment is a Loan Document.  Except as affected by this Amendment, the Loan Documents are unchanged and continue in full force and effect.  However, in the event of any inconsistency between the terms of the Credit Agreement as amended by this Amendment and any other Loan Document, the terms of the Credit Agreement will control and the other document will be deemed to be amended to conform to the terms of the Credit Agreement.  All references to the Credit Agreement will refer to the Credit Agreement as amended by this Amendment and any other amendments properly executed among the parties.  Borrower and each other Obligor agree that all Loan Documents to which they are a party (whether as an original signatory or by assumption of the Obligations) remain in full force and effect and continue to evidence their legal, valid and binding obligations enforceable in accordance with their terms (as the same are affected by this Amendment or are amended in connection with this Amendment).  Borrower and each other Obligor release Lender from any liability for actions or failures to act in connection with the Loan Documents prior to the date of this Amendment.  No course of dealing among Borrower and Lender or any other Person will be deemed to have altered or amended the Credit Agreement or affected either Borrowers or Lenders right to enforce the Credit Agreement as written.  This Amendment will be binding upon and inure to the benefit of each of the undersigned and their respective successors and permitted assigns.  13. Form.  Each agreement, document, instrument or other writing to be furnished to Lender under any provision of this instrument must be in form and substance satisfactory to Lender and its counsel.  14. Multiple Counterparts.  This Amendment may be executed in more than one counterpart, each of which shall be deemed an original, and all of which constitute, collectively, one instrument; but, in making proof of this instrument, it shall not be necessary to produce or account for more than one such counterpart.  It shall not be necessary for Borrower, each other Obligor and Lender to execute the same counterpart hereof so long as Borrower, each other Obligor and Lender each execute a counterpart hereof.  For purposes of this Amendment, an electronic copy of any partys signature to this Amendment shall be deemed an original signature.  15. Governing Law.  This Amendment and all transactions provided for in this Amendment will be governed by, interpreted and construed under and enforced pursuant to the laws of the State of Texas, without regard to its conflicts of laws provisions.  3    16.
