OVERRIDING ROYALTY INTEREST CONVEYANCE

STATE OF FLORIDA		§
COUNTY OF		§

Quantum Resources A1, LP, a Delaware limited partnership (“QRA”), Quantum Resources B, LP, a Delaware limited partnership (“QRB”), Quantum Resources C LP, a Delaware limited partnership (“QRC”), QAB Carried WI, LP, a Delaware limited partnership (“QAB”), QAC Carried WI, LP, a Delaware limited partnership (“QAC”), and Black Diamond Resources, LLC, a Delaware limited liability company (“Black Diamond” and, together with QRA, QRB, QRC, QAB and QAC, “Assignor”), each of whose address is ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, for good and valuable consideration, the receipt of which is hereby acknowledged, effective as of 12:01 a.m. on ___________ (the “Effective Time”) does hereby GRANT unto QRE Operating, LLC, a Delaware limited liability company, whose address is ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇ (“Assignee”) an overriding royalty interest in, to and under each of the oil and gas leases described on Exhibit A attached hereto (collectively the “Leases”, individually a “Lease”) equal to 8.05% of 8/8ths in and to the Oil Hydrocarbons (as hereinafter defined) in and under and that may be produced and saved from the Leases (the “ORRI”) subject to the terms and provisions set forth herein.

     As used herein, (i) “Contribution Agreement” shall mean that certain Contribution, Conveyance and Assumption Agreement, dated as of [________], among Assignor, Assignee, QRE GP, LLC and QR Energy, LP, and (ii) “Oil Hydrocarbons” shall mean crude petroleum oil only, excluding any natural gas liquids or gaseous hydrocarbons produced in connection therewith. Capitalized terms used but not defined herein shall have the meanings ascribed thereto in the Contribution Agreement.

     The ORRI is subject to all applicable laws, rules, regulations and orders of Governmental Authorities.

     The ORRI is a non-operating, non-expense-bearing overriding royalty interest in the nature of an interest in real and/or immovable property, free of all cost, risk and expense of production and operations and delivery including all drilling, developing, operating and transportation costs and expenses, provided that the valuation of the Oil Hydrocarbons attributable to the ORRI shall be made in the same manner and under the same conditions as is provided in said Leases for the payment and delivery of royalties to the lessors under the applicable Lease. In addition, Assignee shall bear and pay all production and ad valorem taxes that may now or hereafter be applicable to the ORRI or the production of Oil Hydrocarbons attributable thereto. In no event shall Assignee ever be liable or responsible in any way for the payment of any costs, expenses, or liabilities attributable to the Leases (or any part thereof) or incurred in connection with the production, saving or delivery of Oil Hydrocarbons produced related thereto. Assignor agrees to tender payment of the ORRI to Assignee at the same time and in the same manner as royalty payments are made to the lessor under the applicable Lease. This Overriding Royalty Interest Conveyance (this “Conveyance”) is an absolute conveyance of an interest in real and/or immovable property.

     The ORRI shall not apply to, and in any event shall not be paid or accrued upon, any Oil Hydrocarbon used for operating, development or production purposes upon the lands covered by the Leases or unavoidably lost, and the ORRI shall not apply to and shall not be paid with respect to Oil Hydrocarbons used in re-pressuring or recycling operations or pressure maintenance operations benefiting the lands covered by the Leases.

     If Assignor owns less than 100% of the leasehold interest under a Lease, or in the event a Lease covers less than the full fee mineral estate, then the ORRI shall be reduced proportionately with respect to Assignor’s interest in such Lease or the partial fee mineral interest covered by such Lease.

     Subject to prior calls on production or other such commitments existing as of the date hereof, Assignee may elect to receive the ORRI in kind if it so elects by giving Assignor at least 30 days advance written notice. If Assignee elects to take its Oil Hydrocarbons attributable to the ORRI in kind then as between Assignor and Assignee, Assignor shall be in exclusive control and possession of the Oil Hydrocarbons produced related to the ORRI delivered hereunder and responsible for any loss, damage or injury caused thereby until the same shall have been delivered to Assignee at the agreed delivery point for such Oil Hydrocarbons, after which delivery Assignee shall be deemed to be in exclusive control and possession thereof and responsible for any loss, injury, or damage caused thereby. To the extent it has the legal and contractual right to do so, Assignor hereby grants to Assignee easements and rights-of-way over and across the Leases and lands pooled, communitized and/or unitized therewith, together with rights of ingress and egress, for the purposes of receiving, accepting, and taking the ORRI, and to the extent necessary, the construction, maintenance, operation, and repair, of pipelines, metering stations, and any and all other facilities and appurtenances necessary or useful related to the receipt, transportation, measurement, treatment, and marketing of the ORRI.

     The ORRI shall be free of (and without deduction therefrom of) any and all royalties and other burdens on production and shall bear no part of the same. Assignor’s retained leasehold interests shall be burdened with, and Assignor shall be responsible for the timely payment of all such royalties, overriding royalties, and other burdens on production, and Assignor shall defend, indemnify, and hold Assignee harmless from and against any loss or claim with respect to any such royalties, overriding royalties, or other burdens on production or any claim by the owners or holders of such royalties, overriding royalties, or other burdens on production.

     The ORRI shall be applicable to any renewal, extension, or new lease taken or acquired by Assignor, or its successors or assigns, within two years after the date of termination of the Leases covering all or any part of the same property and Oil Hydrocarbons minerals.

     Except to the extent expressly provided in any other document executed in connection with the Contribution Agreement or the Offering, the grant of the ORRI pursuant to this Assignment is made expressly subject to all recorded and unrecorded liens (other than consensual liens), encumbrances, agreements, defects, restrictions, advance claims and all laws, rules, regulations, ordinances, judgments and orders of Governmental Authorities or tribunals having or asserting jurisdiction over the ORRI and operations conducted in connection with the Leases, in each case to the extent the same are valid and enforceable and affect the ORRI, including all matters that a current survey or visual inspection of the Leases would reflect.

     EXCEPT TO THE EXTENT PROVIDED IN ANY OTHER DOCUMENT EXECUTED OR DELIVERED IN CONNECTION WITH THE CONTRIBUTION AGREEMENT OR THE OFFERING, ASSIGNOR AND ASSIGNEE ACKNOWLEDGE AND AGREE THAT NO PARTY HAS MADE, DOES NOT MAKE, AND EACH SUCH PARTY SPECIFICALLY NEGATES AND DISCLAIMS, ANY REPRESENTATIONS, WARRANTIES, PROMISES, COVENANTS, AGREEMENTS OR GUARANTIES OF ANY KIND OR CHARACTER WHATSOEVER, WHETHER EXPRESS, IMPLIED OR STATUTORY, ORAL OR WRITTEN, PAST OR PRESENT, REGARDING (A) THE VALUE, NATURE, QUALITY OR CONDITION OF THE LEASES, INCLUDING THE WATER, SOIL, GEOLOGY OR ENVIRONMENTAL CONDITION OF THE LEASES GENERALLY, INCLUDING THE PRESENCE OR LACK OF HAZARDOUS SUBSTANCES OR OTHER MATTERS ON THE PROPERTIES UNDERLYING THE LEASES, (B) THE INCOME TO BE DERIVED FROM THE ORRI, (C) THE SUITABILITY OF THE LEASES FOR ANY AND ALL ACTIVITIES AND USES THAT MAY BE CONDUCTED THEREON, (D) THE COMPLIANCE OF OR BY THE LEASES OR THEIR OPERATION WITH ANY LAWS (INCLUDING ANY ZONING, ENVIRONMENTAL PROTECTION, POLLUTION OR LAND USE LAWS, RULES, REGULATIONS, ORDERS OR REQUIREMENTS), OR (E) THE HABITABILITY, MERCHANTABILITY, MARKETABILITY, PROFITABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE LEASES. EXCEPT TO THE EXTENT PROVIDED IN ANY OTHER DOCUMENT EXECUTED OR DELIVERED IN CONNECTION WITH THIS CONTRIBUTION AGREEMENT OR THE OFFERING, ASSIGNOR AND ASSIGNEE ACKNOWLEDGE AND AGREE THAT EACH HAS HAD THE OPPORTUNITY TO INSPECT THE LEASES AND RELATED PROPERTIES, AND EACH IS RELYING SOLELY ON ITS OWN INVESTIGATION OF SUCH AND NOT ON ANY INFORMATION PROVIDED OR TO BE PROVIDED BY ANY OTHER PARTY. NONE OF ASSIGNOR NOR ASSIGNEE IS LIABLE OR BOUND IN ANY MANNER BY ANY VERBAL OR WRITTEN STATEMENTS, REPRESENTATIONS OR INFORMATION PERTAINING TO THE ORRI OR THE LEASES FURNISHED BY ANY AGENT, EMPLOYEE, SERVANT OR THIRD PARTY. EACH SUCH PARTY ACKNOWLEDGES THAT TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE GRANT OF THE ORRI AS PROVIDED FOR HEREIN IS MADE IN AN “AS IS”, “WHERE IS” CONDITION WITH ALL FAULTS, AND THE ORRI IS GRANTED SUBJECT TO ALL OF THE MATTERS CONTAINED IN THIS SECTION. THE PROVISIONS OF THIS SECTION HAVE BEEN NEGOTIATED BY ASSIGNOR AND ASSIGNEE AFTER DUE CONSIDERATION AND ARE INTENDED TO BE A COMPLETE EXCLUSION AND NEGATION OF ANY REPRESENTATIONS OR WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, WITH RESPECT TO THE ORRI THAT MAY ARISE PURSUANT TO ANY LAW NOW OR HEREAFTER IN EFFECT, OR OTHERWISE.

     Each of Assignor and Assignee agrees that the disclaimers contained in the immediately preceding paragraph are “conspicuous” disclaimers. Any covenants implied by statute or law by the use of the words “contribute,” “distribute,” “assign,” “grant,” “transfer,” “deliver” or “set over” or any of them or any other words used in this ORRI conveyance document are hereby expressly disclaimed, waived or negated.

     Assignor and Assignee acknowledge that pursuant to the Contribution Agreement (a) each Assignor agreed to contribute, assign, transfer, set over and deliver to QR Energy, LP (the

“Partnership”) all of its right, title and interest to and in the MLP Assets (as defined in the Contribution Agreement), including the ORRI, as a capital contribution, and (b) the Partnership has agreed to contribute, assign, transfer, set over and deliver to Assignee all of its right, title and interest to and in the MLP Assets, including the ORRI, as a capital contribution, upon the terms set forth in the Contribution Agreement. For convenience and recording purposes, the Partnership requested that each Assignor convey directly to Assignee all of its right, title and interest to and in the MLP Assets, including the ORRI.

     All recording references in Exhibit A are to the appropriate records of the counties in which the Leases are located.

     THIS CONVEYANCE SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF FLORIDA, EXCLUDING ANY CONFLICTS OF LAW RULE OR PRINCIPLE THAT MIGHT REFER CONSTRUCTION OF SUCH PROVISIONS TO THE LAWS OF ANOTHER JURISDICTION, EXCEPT TO THE EXTENT THAT THE LAWS OF ANOTHER STATE ARE MANDATORILY APPLIED TO THE DISPUTED MATTER.

     This Conveyance shall bind and inure to the benefit of the parties hereto and their respective successors and assigns.

     This Conveyance may be executed in any number of counterparts, and each counterpart hereof shall be deemed to be an original instrument, but all such counterparts shall constitute but one instrument. Any signature hereto delivered by a party by facsimile transmission shall be deemed an original signature hereto. Exhibit A may be redacted for filing in each county, such that the exhibit filed in any county will describe only those Leases located in such county.
