Number is 94-0744280 ("Grantor"), to Duke Capital Partners, LLC, a Delaware limited liability company, whose mailing address is 128 South Tryon Street, Suite 1100, Charlotte, North Carolina, 28202, and whose Federal Tax I.D. Number is 56-2186625 ("Grantee"). WHEREAS, Grantor is the owner of an interest in the oil and gas leases described in Exhibit A hereto, and Grantor has agreed to convey to Grantee the Overriding Royalty Interest as defined in Section 1.1 below, as a condition of that certain Credit Agreement dated June 29, 2001, by and among Callon Petroleum Company, as Borrower thereunder, the lenders signatory thereto and Grantee, as Administrative Agent thereunder (the "Credit Agreement"), pursuant to that certain letter agreement dated the date hereof between Callon Petroleum Company and Grantee; and WHEREAS, capitalized terms as used herein shall have the meanings given to them in Article II hereof unless otherwise defined herein. NOW, THEREFORE, KNOW ALL MEN BY THESE PRESENTS: ARTICLE 1 CONVEYANCE SECTION 1.1 CONVEYANCE. For and in consideration of $1,000.00 and other good and valuable consideration to Grantor cash in hand paid by Grantee, the receipt and sufficiency of which is hereby acknowledged, Grantor hereby GRANTS, BARGAINS, SELLS, CONVEYS, ASSIGNS, SETS OVER, AND DELIVERS unto Grantee, its successors and assigns, effective as of the Effective Time, an overriding royalty interest in and to each of the Leases equal to the Overriding Royalty Percentage of all Hydrocarbons produced and saved from each of the Leases, together with all and singular the rights and appurtenances thereto in anywise belonging (the "Overriding Royalty Interest"). TO HAVE AND TO HOLD the Overriding Royalty Interest unto Grantee, its successors and assigns forever, subject to the following terms, reservations, rights of first refusal, provisions and conditions. SECTION 1.2 REPURCHASE OPTION AND RIGHT OF FIRST REFUSAL. (a) Grantor hereby RETAINS and RESERVES unto itself, its successors and assigns, an option ("Repurchase Option") to repurchase this Overriding Royalty Interest in all or any Property in the event that Grantor has a binding contract to sell its interest in such Property to a bona-fide third party purchaser. The repurchase price to be paid to Grantee by Grantor shall be proportional to such bona-fide third party purchaser's purchase price attributable to such Property. Grantee hereby accepts this Conveyance subject to and acknowledges that the Overriding Royalty Interest is burdened by such Repurchase Option. In connection with a sale of all or substantially all of Grantor's interest in any Property to a bona-fide third party purchaser, Grantor may give Grantee written notice stating the terms and conditions of such offer ("Grantor's Offer Notice") and Grantee shall agree to sell its Overriding Royalty Interest to Grantor on or before the same day Grantor's interest is sold at the price described above on an "as is-where is" basis without representation or warranty or indemnity of any kind except as to title with respect to any claims by, through and under Grantee. (b) If Grantee desires to sell, assign, convey or transfer all or any portion of its Overriding Royalty Interest in any Property (the "Interest"), Grantee shall give written notice ("Grantee's Offer Notice") to Grantor stating that Grantee desires to effect such transfer and setting forth the material terms thereof. The giving of the Grantee's Offer Notice by Grantee to Grantor shall constitute an offer by Grantee to sell the Interest to Grantor pursuant to the terms set forth in the Grantee's Offer Notice. Grantor shall have 15 days after its receipt of the Grantee's Offer Notice in which to accept such offer by giving written notice of acceptance to Grantee prior to the expiration of such 15-day period. If Grantor accepts such offer, Grantee and Grantor shall exercise their commercially reasonable efforts to effectuate the transfer as between them as soon as practicable. If Grantor rejects in writing the offer set forth in the Grantee's Offer Notice, or fails to respond within 15 days after its receipt of the Grantee's Offer Notice, Grantee may consummate the sale to any bona-fide third party purchaser, but only on terms equal to or better than those set forth in the Grantee's Offer Notice. If Grantee does not consummate the sale within 90 days after receipt of written refusal by Grantee or expiration of the 15-day period, as applicable, Grantee's right to effectuate the sale shall lapse, and Grantee shall be required to again provide Grantor with a Grantee's Offer Notice, provided, however, no such conveyance shall be valid until Grantor has received a certified copy of such conveyance. This Section 1.2 shall not apply with regard to conveyances of Interests in connection with Grantee's initial syndication of the Facility (as such term is defined in the Credit Agreement). SECTION 1.3 NON-OPERATING, NON-EXPENSE BEARING INTEREST. The Overriding Royalty Interest conveyed hereby is a non-operating, non-expense-bearing overriding royalty interest in the nature of an interest in real property, free of all costs, risks and expenses, except to the extent (i) any such costs and expenses are properly deductible in calculating the lessor's royalties payable under the Leases to the United States Minerals Management Service ("MMS") and/or (ii) any such costs and expenses are paid to unaffiliated third parties in arms-length transactions (or affiliated entities at market rates) and directly attributable to marketing, gathering, and delivering the Hydrocarbons to the initial sales points, provided, however, that in no event shall such costs and expenses be greater than proportionately equal to the costs and expenses that are paid or payable by Grantor with respect to its interest in Hydrocarbons produced from the Subject Interests ("Deductible Costs"). In no event shall Grantee ever be liable or responsible in any way for the payment of any costs, expenses, or liabilities attributable to the Subject Interests (or any part thereof) or incurred in connection with the exploration, production, operations or delivery of Overriding Royalty Hydrocarbons to the initial sales points except as provided in the preceding sentence. SECTION 1.4 MARKETING OF OVERRIDING ROYALTY HYDROCARBONS. Grantor shall market or cause to be marketed the Overriding Royalty Hydrocarbons in the same manner as Grantor markets or causes to be marketed Hydrocarbons attributable to its Net Revenue Interest, as a reasonable and prudent operator. Grantor shall pay, or cause to be paid, to Grantee the amount due in respect of the Overriding Royalty Hydrocarbons that are produced and sold in -2- any month no later than 26 days following the month in which the revenues attributable to the sale of such Overriding Royalty Hydrocarbons are received by Grantor. SECTION 1.5 CERTAIN LIMITATIONS. Grantee shall look solely to the Overriding Royalty Hydrocarbons for satisfaction and discharge of the Overriding Royalty Interest, and Grantor shall not be personally liable for the payment and discharge thereof. SECTION 1.6 ROYALTIES; TAXES. The Overriding Royalty Hydrocarbons shall be calculated as two percent (2%) of Grantor's Net Revenue Interests in the Leases, with the result that the Overriding Royalty Hydrocarbons shall be determined net of all Hydrocarbons allocable or otherwise attributable to all royalties, overriding royalties (other than the Overriding Royalty Interest), and other burdens on production allocable or otherwise attributable to the Subject Interests that are reflected of record as of the Effective Time. Grantor shall be responsible for the timely payment of all such royalties, overriding royalties, and other burdens on production, and Grantor shall defend, indemnify, and hold Grantee 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 by, through or under Grantor, but not otherwise. Grantee shall bear and pay all Taxes, income and franchise taxes attributable to the Overriding Royalty Interest and the Overriding Royalty Hydrocarbons or attributable to Grantee. SECTION 1.7 TITLE. Grantor warrants and represents that the Leases are valid and subsisting oil and gas leases covering the lands or waterbottoms described in Exhibit A; subject to the Leases and Permitted Encumbrances, Grantor's ownership of the Subject Interests entitles Grantor to a share of all Hydrocarbons produced from or attributable to each Lease, and of the proceeds of such production, after giving effect to and/or deducting all applicable royalties, overriding royalties, and other burdens or payments out of production (except the Overriding Royalty Interest), which is not less than the Net Revenue Interest applicable to the relevant Lease, as set forth in Exhibit A associated therewith. Grantor hereby binds Grantor and Grantor's legal representatives, successors, and assigns to warrant and forever defend all and singular title to the Overriding Royalty Interest and the Overriding Royalty Hydrocarbons unto Grantee, its successors and assigns, against every person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Grantor, but not otherwise; provided however, the foregoing warranty shall not be breached in any manner by the existence of the Permitted Encumbrances. SECTION 1.8 MORTGAGE OR ASSIGNMENT BY GRANTOR. Except for Permitted Encumbrances which do not create a lien to secure an obligation for borrowed money, Grantor shall not mortgage, pledge, or hypothecate the Overriding Royalty Interest or create or allow to remain thereon any lien or security interest on any Overriding Royalty Hydrocarbons produced therefrom. Any purported mortgage, pledge, hypothecation, lien, security interest, assignment, sale, conveyance, or other transfer in contravention of the foregoing terms shall be null and void. SECTION 1.9 POOLING OR UNITIZATION. This Conveyance is subject to all applicable valid pooling or unitization orders, declarations or agreements affecting any of the Leases or any part thereof, currently or in the future. Further, in the event that the owners of the Leases, or the applicable regulatory authorities, shall hereafter at any time or times create, amend, terminate or declare a pool or unit for the development or production of Oil and/or Gas -3- that includes all or any part of any of the Leases, then in each such event such pooling or unitization shall be binding upon and effective with regard to the Overriding Royalty Interest insofar as it applies to the Leases included in such pool or unit, without the necessity of Grantee's further consent to or approval of such pool or unit. SECTION 1.10 OPERATIONS. Grantor is under no obligation or duty, insofar as Grantee is concerned, to pay any delay rentals or minimum royalties becoming due under any of the Leases or otherwise to maintain any of the Leases in force or effect by extending same or by operations thereon or production of Oil, Gas, or other minerals, in any quantity therefrom, and the payment of any such delay rentals, minimum royalties, taking of extensions or conduct or cessation of operations or production of Oil, Gas, or other minerals under the Leases shall be, as between the parties, at the sole discretion of Grantor. Furthermore, this Conveyance shall not give rise to or create any obligation for Grantor to obtain Grantee's consent or joinder or comply with any demand of Grantee, with respect to the maintenance, operation (e.g. the decision to drill, complete, rework or abandon wells), or abandonment of any platform or other exploration, production, handling or treating facility, or the Leases, and the execution of contracts related thereto. SECTION 1.11 SCOPE OF THE OVERRIDING ROYALTY INTEREST. The Overriding Royalty Interest shall not apply to Hydrocarbons lost, flared, vented or used in support of producing, handling, transporting and processing Hydrocarbons derived from or attributable to the Leases. The Overriding Royalty Interest shall not apply to any Hydrocarbons attributable to Grantor's Net Revenue Interest that are subject to a right of recoupment, forfeiture or relinquishment under the applicable joint operating agreements; provided, however, the Overriding Royalty Interest shall apply to any such Hydrocarbons if and when the Hydrocarbons are no longer subject to such right of recoupment, forfeiture or relinquishment. SECTION 1.12 SETTLEMENT. Grantee shall participate proportionately in any in-kind or cash settlements received by Grantor for underproduction of Hydrocarbons attributable to the Overriding Royalty Interest. Likewise, Grantee shall have the obligation to participate in or reimburse Grantor as to Grantee's proportionate share of any in-kind or cash settlements made or paid by Grantor for overproduction of Hydrocarbons attributable to the Overriding Royalty Interest. SECTION 1.13 PRUDENT STANDARD. Grantor (subject to the terms and provisions of any applicable operating agreements and subject to the other provisions of this Conveyance and the Credit Agreement) shall take any and all actions which a reasonably prudent non-operator would deem necessary or advisable in the management, operation and control of the Subject Interests, including, without limitation, the plugging and abandonment of any Hydrocarbon well located on the Leases in accordance with good oil field practices without regard to the existence of the Overriding Royalty Interest or any other royalty, overriding royalty, or other interest created after the Effective Time. SECTION 1.14 ROYALTY RELIEF. To the extent any of the Leases are entitled to royalty relief pursuant to the regulations of the MMS, Grantee as the owner of the Overriding Royalty Interest shall be entitled to two percent (2%) of such royalty relief that is attributable to Grantor's Net Revenue Interest shown on Exhibit A. -4- SECTION 1.15 RESTRICTIONS ON SUBSEQUENTLY CREATED INTERESTS. To the extent required by the express terms and provisions of any of the Permitted Encumbrances identified in Exhibit B to this Conveyance, Grantor and Grantee acknowledge and agree that this Conveyance is inferior to and is made expressly subject to such Permitted Encumbrances, and Grantor acknowledges and agrees that it shall indemnify and hold all of the parties to such Permitted Encumbrances, other than itself, harmless from any and all claims and demands for payment that may be asserted by Grantee as the owner of the Overriding Royalty Interest.
