Any Substitute Location drilled hereunder shall be drilled subject to the same terms and conditions and to the same depth as provided for the said well. Any reference herein or hereinafter made to the said well shall be deemed to be a reference to any Substitute Locations which may be drilled therefor. 4. EARNING INTERESTS. RRE hereby grants to Avalon a continuous drilling option on the Pilot Project area. Avalon may exercise its option to receive rights and interests in the Pilot Project upon commencement of operations to drill the first Pilot Well in the Pilot Project. Avalon shall have such an option for the Pilot Project if such operations to drill commence on or before September 30, 2000. If Avalon timely commences such first Pilot Well, Avalon shall earn 100% of RRE's right, title and interest in the Pilot Well Production from each respective Pilot Well and Spacing Unit containing such Pilot Well within an applicable Pilot Project. After commencement of the first Pilot Well, the Pilot Project Wells may be conducted in any order determined by Avalon and its obligation to commence a Pilot Well shall be satisfied if a Pilot Well in the Pilot Project is timely commenced as hereafter provided. To earn such interest in each subsequent Pilot Well Production and corresponding Spacing Units, Avalon must commence operations for the drilling of each subsequent Pilot Well within thirty (30) days from the Completion Date of the previous Pilot Well or such continuous drilling option shall expire, subject to the notice requirements provided in Section 12 hereon. RRE will allow Avalon a 90 day testing and evaluation period after the Completion Date of the fourth (4th) well and the commencement of operations of the fifth (5th) well of the Pilot Project. Should Avalon timely commence each consecutive Pilot Well, Avalon will maintain and continue its right to drill and complete consecutive Pilot Wells within the Pilot Project until Completion of the Pilot Project. 4 5. ASSIGNMENT OF INTERESTS. Upon the Completion Date of each Pilot Well or JVDA Well drilled within a Pilot Project or the JVDA, RRE agrees to assign all its right, title and interest in the Pilot Well Production from the completed Pilot Well and 60% of RRE's right title and interest in the JVDA Well Production from the completed JVDA Well, subject to RRE's election to participate with its 40% interest as provided herein, in the corresponding Spacing Unit. Title to the leasehold for the Hunton rights is derived from RRE's respective ownership in the entire WEHLU; however, Avalon's earning interest will be limited to Pilot Well Production or JVDA Production received by virtue of the Pilot Wells or JVDA Wells drilled in each respective Spacing Unit. Depth of rights earned will be from the surface to the base of the stratigraphic equivalent of total depth drilled in each Pilot Well or JVDA Well and further limited to those leasehold rights RRE actually owns. Assignment of rights lying outside the Hunton formation will be done for each Spacing Unit as rights are earned limited to those leasehold rights RRE actually owns. RRE will retain all right, title and interest in and to all production from the Unit Wells, if any, within the Pilot Project or the JVDA. RRE grants Avalon the right to operate, drill, inject, dispose fluids into any and all formations which RRE presently owns the leasehold and operating rights to inject said fluids in the WEHLU. All Pilot Wells shall be drilled to the Contract Depth. The interests earned as specified above shall be conveyed and assigned to Avalon with covenants of special warranty for each Pilot Well, JVDA Well and applicable Spacing Unit pursuant to the applicable form of Assignment attached hereto as Exhibit "B". The assignments for each such well and Spacing Unit and any future assignments for future wells and Spacing Units shall be in a recordable form for the applicable recording offices, shall be otherwise acceptable to Avalon and shall be delivered to Avalon within thirty (30) days after the Completion Date of each Pilot Well or JVDA Well. The assignment shall be made subject to the terms of the WEHLU and to all royalties, overrides and other lease burdens currently existing, but shall otherwise be free and clear of all liens, encumbrances and claims of any kind. Additionally, the parties may hereafter designate an AMI. If either Avalon or RRE shall own or hereafter acquire any additional leases or rights within the AMI, said party, as soon as possible, shall provide the other party the details of such interest, including purchase price, acreage amounts, description and acquisition costs. Such party shall then have twenty (20) days from receipt of such information to elect whether it wishes to pay its proportionate share (based on each parties respective participating working interest) of the costs and acquire its proportionate share of the leases or rights. In the event such party does not make an election within the twenty (20) day period, or elects not to participate in the acquisition, the leases and rights offered shall not be considered subject to this Agreement and the AMI, and such party shall be deemed to have waived any present or future claim to said leases or rights. Any such leases or rights owned or acquired by the consenting party shall be operated, developed and produced outside the terms and conditions of this Agreement and shall be subject to other joint operating agreements and documentation. By written agreement between Avalon and RRE, the AMI may be expanded or contracted as may be mutually agreed. Any renewal or extension of any leases or rights previously offered and not accepted, shall not be required to be reoffered. 5 6. OWNERSHIP OF INTERESTS. RRE represents that it owns an approximate 97% Unit leasehold interest in Hunton rights only within the WEHLU and controls field operations with respect to the WEHLU. WEHLU is currently a valid existing unit, which has been duly and properly established and maintained in accordance with applicable Oklahoma law. RRE will deliver to Avalon an average 80.0% net revenue interest on all interests delivered under this Agreement. 7. RIGHT TO REPURCHASE. ------------------- Avalon hereby grants to RRE an option to repurchase from Avalon 40% of RRE's original interest in the Pilot Project, proportionately reduced. Such option shall be exercised in writing and delivered to Avalon within one hundred twenty (120) days of the Completion Date of the last Pilot Well in the Pilot Project. The repurchase price shall be an amount equal to 40% of the actual costs incurred by Avalon in drilling and completing the Pilot Wells for the Pilot Project. Avalon agrees to reassign such interest free and clear of all liens, overriding royalty interests, or encumbrances not of record prior to Avalon's acquisition of such interest from RRE. Should RRE elect not to exercise its option to repurchase or shall fail to timely elect to repurchase, this option shall terminate and all right, title, and interest of RRE to such 40% option interest shall be null and void. 8. JVDA WELLS. ---------- Upon completion and development of the Pilot Project, Avalon shall have the continuing right to develop the remaining portion of the WEHLU constituting the JVDA on a joint venture basis with RRE. The terms of such venture shall be as follows: (a) Avalon will have the right to earn 64.0% of the JVDA Production attributable to RRE's ownership position in the JVDA on a continuous drilling to earn basis. (b)All JVDA Production attributable to RRE's acreage acquired by Avalon pursuant to Section 8(a) above in the JVDA will be subject to Avalon paying all drilling, testing, completing, and equipping costs equal to a 6.25% carried working interest to the tanks (i.e. ready for production) for the benefit of RRE, proportionately reduced to Avalon's actual interest acquired in each respective Spacing Unit for each JVDA Well. (c) RRE will deliver to Avalon an average 80.0% net revenue interest equal to the same terms as specified in Section 6 above. (d) RRE will retain the right to participate in all JVDA Wells in the JVDA with 36.0% of its original leasehold interest in each Spacing Unit. Should RRE elect to participate with its 36.0% interest, said interest shall be in addition to the carried working interest set out in Section 8(b) above. For illustrative purposes only, each parties' JVDA unit working interest, should all parties elect to participate with their full interest, would be as follows, proportionately reduced: Working Interest Before Production in the Tanks: Avalon- 64.0%, RRE- 36.0%; Working Interest After Production in the Tanks: Avalon- 64.0% less (64.0% x 6.25%) = 60.0%, RRE- 36.0% plus (64.0% x 6.25%) = 40.0%. 6 (e) Avalon shall provide written notice of any proposed JVDA Well to RRE and RRE shall then have twenty (20) days from receipt of such notice to elect whether it wishes to participate in such JVDA Well. In the event RRE does not make an election within the twenty (20) day period, or elects not to participate in the JVDA Well, Avalon will have the right of first refusal to acquire and participate with such interest. Such right of first refusal shall be exercised by written notification from Avalon to RRE within thirty (30) days after the expiration of RRE's twenty (20) day election period. RRE shall retain its right to the 6.25% carried working interest in wells in which it does not elect to participate. (f) Within one hundred eighty (180) days from the Completion Date of the final Pilot Well in the Pilot Project, Avalon must notify RRE in writing of its desire to develop the JVDA and commence operations on the initial JVDA Well in the JVDA. The parties agree that such one hundred eighty (180) day period is intended to be sufficient time to evaluate the production success from the Pilot Project; however, should additional time be needed to evaluate the success of the Pilot Project, Avalon will request such extension from RRE in writing, and RRE shall not unreasonably withhold its consent thereto. (g) Avalon will continue to develop the JVDA on a well by well basis within applicable Spacing Units with no more than thirty (30) days elapsing between the Completion Date of one JVDA Well and the commencement of operations on the subsequent JVDA Well. (h) For any JVDA Well, the drilling and spacing earning units in the JVDA shall be Spacing Units of 160 acre units, unless hereafter modified by the written agreement of the parties. 9 OPERATIONS. (a) RRE or one of its Affiliates is presently the legal unit operator of the WEHLU as recognized by the Oklahoma Corporation Commission. RRE hereby grants Avalon the right to be contractual operator of all Pilot Wells in the Pilot Project and all JVDA Wells in the JVDA, notwithstanding that RRE shall continue to be the unit operator of WEHLU and continue to be responsible and obligated for all unit operating requirements established by the WEHLU unitization agreement. RRE will retain the right and obligation to operate the WEHLU for all Unit Wells presently in existence and be the legal operator of all Pilot Wells and JVDA Wells drilled by Avalon. RRE agrees to support Avalon in any Oklahoma Corporation Commission or other governmental filings necessary to conduct operations under this Agreement within the boundaries of the WEHLU. (b) Avalon shall have the responsibility for all operations involved with the drilling and completion of the Pilot Wells and JVDA Wells hereunder and for causing each such well that is capable of producing in Paying Quantities to be hooked-up to the appropriate separation facilities and gathering system. Avalon shall perform all the activities and functions normally performed by an operator as a contract service to the working interest owners in the Pilot Project and JVDA Wells. Avalon's contract operational rights and responsibilities shall be evidenced by the Joint Operating Agreement. In the event any provision of the Joint Operating Agreement conflicts with or is contrary to the terms and conditions of this Agreement, the terms and conditions of this Agreement shall govern and control. Any reference in the Joint Operating Agreement to Avalon being the operator shall be deemed to be Avalon as a contract operator under this Agreement. The services, materials, and equipment for such wells shall be procured and used by Avalon in accordance with this Agreement and shall be subject to the 7 interests of Avalon and RRE as provided herein. Upon the Completion Date of each well completed as a well capable of producing oil/and or gas in Paying Quantities, Avalon shall continue to be contract operator and RRE shall continue to be operator of record and Avalon agrees to conduct operations in accordance with the Operations Contract, the form of which is attached hereto as Exhibit "D". (c) Prior to the commencement of drilling operations on each Pilot Well or JVDA Well, Avalon shall prepare a well program for the drilling and completion of the well. Avalon will conduct its operations of such well in accordance with the terms and conditions of the Joint Operating Agreement. (d) In performing the drilling program contemplated hereunder, the parties acknowledge that Avalon shall not be obligated to provide services or Third Party Charges for drilling any well beyond the depth specified on the appropriate well program. Should Avalon determine that continued drilling operations on any well have become uneconomical due to unforeseen conditions or circumstances, then Avalon may discontinue further drilling and may commence such further services Avalon deems necessary to determine whether completion operations should be undertaken. Avalon shall provide RRE twenty-four (24) hours notice of Avalon's intent to log a well so that RRE may have a representative present. Upon completion of such log, Avalon shall have the right to make an election to proceed with completion or plugging and abandonment of the well. (e) RRE shall perform the duties of the operator in accordance with all operating agreements applicable to the Unit Wells and the WEHLU unitization agreement. Avalon agrees to perform or cause to be performed all of its duties and obligations under this Agreement, including, without limitation, with respect to the Pilot Wells and JVDA Wells, the operation of such wells in good faith, in a workmanlike and prudent manner, in conformity with accepted and prudent oil and gas industry standards of operations, in full compliance in all material respects with all applicable federal, state, and local laws, rules, and regulations and in material compliance with all expressed or implied obligations of the lessee under all leases subject hereto and assigned hereunder and in material compliance with the WEHLU unitization agreement. Notwithstanding the above, RRE shall be responsible for collection and distribution of all revenues attributable to the Pilot Wells, the JVDA Wells and the Unit Wells, provided, however, that Avalon shall have the right (i) to assume the administrative functions for revenue distribution under the Pilot Wells and/or the JVDA Wells, and/or (ii) to assume the responsibilities for marketing oil and gas from the Pilot Wells and/or the JVDA Wells, upon twenty (20) days prior written notice to RRE and the written agreement/consent of RRE. The assumption of these functions shall not relieve RRE of its obligations and responsibilities as operator of WEHLU. Avalon shall be responsible for the payment of all Expenditures on any Pilot Well or JVDA Well. RRE shall be responsible for the payment of all Expenditures on all Unit Wells. (f) Avalon covenants and agrees to use prudent, good faith, and reasonable efforts (and to devote sufficient numbers of its employees and adequate amounts of equipment and machinery) to maintain production from each Pilot Well and JVDA Well operated by it pursuant to this Agreement, all in accordance with industry standards, to the extent that a market exists for such production. 8 (g) RRE will promptly make all filings, elections, and applications and will promptly take such other action (including, without limitation, price re-determination) as may be necessary to establish and obtain the highest maximum pricing category and highest price reasonably available for the oil or gas production from the wells, subject to existing oil or gas purchase contracts. In the negotiation of future contracts for the sale of production from the wells, RRE will use its best efforts to obtain the highest price and best terms reasonably available. (h) Gas produced and sold from the Pilot Wells and JVDA Wells completed hereunder will be measured at the wellhead prior to commingling with any other gas stream. Copies of measurement tests and monthly volume statements provided by gas purchasers for the subject wells will be available to Avalon from RRE. RRE covenants to maintain sufficient facilities to be able to conduct, and to conduct no less than semi-annually, sufficient tests for each well, so as to be able to allocate the quantities of gas produced back to the well producing such gas within a degree of accuracy normally acceptable within the industry for gas and wells of this nature. RRE shall provide the results of tests to Avalon within ten (10) days after completion of the tests. Avalon shall have the right to inspect the production facilities, surface equipment and meters, to be able to verify the tests and allocations of production for the gas. Oil and condensate produced from the subject wells will be stored and measured separately, before commingling with other well streams. Avalon shall have the right, at its own expense, to determine production and measurement accuracy. Upon request, Avalon shall be provided with advance notice of any meter tests or calibrations so that it may have a representative present to witness such tests. (i) Each party shall notify the other party of every material adverse claim or demand made or threatened to be made by any person (including any government or governmental agency) affecting the Pilot Wells or the JVDA Wells or the proceeds of production therefrom in any manner whatsoever, and of any proceeding instituted with respect thereto. (j)RRE, on behalf of itself and any present or future Affiliates, covenants that it will not contract with any third party pursuant to a sublease, farmout or other arrangement for any Unit Well completed as a producer of oil or gas in Paying Quantities, without Avalon's prior written consent during the productive life of any Pilot Well or JVDA Well hereunder, unless required by applicable statutes, rules, regulations or lease obligations, nor will it drill, propose, or consent to drill additional wells located in a Spacing Unit where a Pilot Well or JVDA Well is drilled or Avalon owns the right to propose and drill a JVDA well pursuant to this agreement. Notwithstanding the foregoing, nothing contained in this subsection shall prohibit RRE from drilling replacement Unit Wells should RRE lose such a well during recompletion operations. 10. ENVIRONMENTAL LIABILITY. RRE, as operator of the WEHLU, shall have all responsibility and liability for any past, present or future generation, handling, storage, transportation, treatment and disposal of all hazardous or toxic substances, pollutants or contaminants ("contamination") at or relating to any Unit Well site in the WEHLU. Avalon, as operator of the Pilot Wells and JVDA Wells, shall have all responsibility and liability for any future generation, handling, storage, transportation, treatment and disposal of all contamination at or relating to any Pilot Well site or JVDA Well site. Each party shall defend and indemnity the other party against all liabilities, obligations, costs and expenses which may arise from a violation of such party's responsibilities described above. 9 11. HEALTH AND SAFETY COMPLIANCE. Avalon and RRE shall each comply with, and require and insure that all contractors or subcontractors, vendors and materialmen which it supervises or controls, comply with all federal, state and local laws and ordinances, or orders, regulations and directives issued by any governmental agency, or any health and safety plan pertaining to the health and safety of persons working or otherwise on any well site. All materials furnished and/or work performed under this Agreement, or any subcontract, by Avalon or RRE or any of their respective contractors or subcontractors under their supervision or control, shall fully comply with all governmental safety and health requirements, including the rules and standards contained in the Occupational Safety and Health Act of 1970, as amended, Federal Mine Safety and Health Act of 1977, as amended, and any other applicable or similar federal, state and local safety or health laws, rules or regulations. Avalon and RRE shall, to the extent either of them prepares, supervises or controls the conditions at any well site, provide all safety equipment, materials, tools and personal protection equipment necessary to insure that work is performed in a safe, healthful and workmanlike manner. 12. FAILURE TO CONDUCT DRILLING OPERATIONS OR DEFAULT. (a) Any failure of Avalon to (i) timely comply with the continuous drilling obligations provided for herein, under circumstances not constituting a force majeure, or (ii) perform or comply with any other provision of this Agreement applicable to Avalon, and with respect to either (i) or (ii) above, after thirty (30) days notice of such event by RRE to Avalon, shall be deemed a default hereunder by Avalon. (b) Any failure of RRE to perform or comply with any provision of this Agreement applicable to RRE after thirty (30) days notice of such event by Avalon to RRE, shall be deemed a default hereunder by RRE. (c) Upon a default by Avalon, RRE shall have the right to (i) terminate this Agreement, and (ii) receive reassignments of its interests except as hereafter provided, and (iii) recover such damages and other relief to which it may be entitled at law or in equity. Notwithstanding the foregoing, if such default occurs prior to the Completion Date of the last Pilot Well in the second Pilot Project, RRE shall be entitled to reassignment of its interests in the Pilot Wells and applicable Spacing Units, but in no event shall Avalon be obligated to reassign or release its interest in those Pilot Wells and applicable Spacing Units unless and until Payout has occurred (whether by prepayment or otherwise). Further, if such default occurs after the Completion Date of the last Pilot Well in the Pilot Project or after any JVDA Well has been completed, RRE shall not be entitled to reassignment of its interests in the Pilot Wells, the JVDA Wells and the applicable Spacing Units, and in no event shall Avalon be obligated to reassign or release its interest in those Pilot Wells, JVDA Wells and applicable Spacing Units. (d) Upon a default by RRE, Avalon shall have the right to any or all of the following: (i) terminate its obligations to drill additional Pilot Wells under this Agreement; (ii) if such default occurs prior to the Completion Date of the last Pilot Well in the Pilot Project, Avalon may, but shall have no obligation to, perform such covenant, agreement or obligation of RRE and any payment made or expense incurred in such performance shall be 10 reimbursed to Avalon by RRE on demand, and, until and unless so reimbursed (other than with revenues from the proceeds of production of the wells), such expenses shall bear interest calculated at the Interest Rate; and (iii) recover its damages and exercise all other remedies available, at law or in equity. In addition to the remedies provided in this subparagraph, Avalon shall be subrogated to the extent permitted by law to all rights, liens, and security interests securing the payment of any debt, claims, tax, or assessment for the payment of which Avalon may make an advance. No such payment or performance by Avalon shall constitute a waiver of any such default by RRE. If Avalon shall provide notice to RRE of Avalon's election to terminate this Agreement, Avalon shall thereafter have no further obligations or duties hereunder to drill such additional wells. Such termination shall not have any effect upon Avalon's right to receive payments as described herein, nor shall it affect the validity of any Assignments provided herein as to Pilot Wells or JVDA Wells already completed or in the process of being completed. Such termination shall not have any effect upon RRE's reversionary rights, rights to repurchase and carried interest hereunder. (e) Any termination of this Agreement shall not affect the obligations specified hereunder that survive termination, including without limitation Section 10& Section 13. (f) Upon RRE's receipt of written notice from Avalon, Avalon may, in its sole discretion, elect to amend completion of a Pilot Project containing fewer than five (5) wells as sufficient performance to continue Avalon's rights under this Agreement. 13. PROTECTION FROM LIENS AND ENCUMBRANCES. The parties shall keep the interests in the WEHLU free and clear from all liens and encumbrances created by the actions or improper inactions of themselves, their agents and their contractors, except (i) those for which a party has disputed in good faith and diligently acts to resolve, and (ii) any mortgage lien encumbering RRE's rights and interests.
