In any 57 58 such revised Exhibit, pursuant to this paragraph, the Tract Participation of the retained previously 58 59 qualified Tracts shall remain in the same ratio one to the other. 59 60 60 61 61 6 1 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 On the effective date of this Agreement and thereafter, all Native Unitized Substances produced hereunder (except any part thereof used in conformity with good operating practices for drilling, operating, camp, and other production or development purposes for enhanced recovery operations in accordance with plan of operation approved by the AO or unavoidably lost) shall be deemed to be produced from the several Tracts or Unitized Land, and for the purpose of determining any benefits accruing under this Agreement, each such Tract shall have allocated to it the percentage of said production equal to its Tract Participation effective hereunder during the respective period such Native Unitized Substances were produced. The amownt of Native Unitized Substances allocated to each Tract shall be deemed to be produced from such Tract irrespective of the location of the wells from which the same produced and regardless of depletion of wells or Tracts. In the absence of a controlling contract or Agreement to the contrary, when two or more leases or part or parts thereof have been combined into a single Tract, the percentage participation assigned to such Tract shall for all purposes be divided among the separate leases or part or parts thereof, which have been put into such Tract, in proportion to the number of surface acres contained in said Tract. For unleased Federal acreage, the Unit Operator must set aside all funds attributable to unleased Federal acreage in an interest earning escrow or trust account. 13. GAS STORAGE OPERATIONS. It is agreed that the Unit Operator shall be allowed hereunder to establish a "gas storage reservoir" comprising the Unitized Formation under the lands shown on Exhibit "A" hereto. The Unit Operator proposes to utilize the said gas storage reservoir for the underground storage of natural gas, whether or not gas injected for the purposes of gas storage is produced from lands subject to this agreement. No gas storage operations shall be conducted prior to the consent, approval or certification of the Federal Energy Regulatory Commission (FERC), or other authorizing agency, allowing gas storage operations. The Unit Operator shall provided notice of such approval to the HIM and the State of Colorado prior to conducting any storage operations, and shall provide an updated Plan of Operations to the AO detailing said storage operations. Upon approval of the authorizing agencies, this date shall be established whereby all gas injection thereafter shall be considered storage gas and subject to the provisions of this Section 13. For the purposes of this agreement, unless directed otherwise by the AO and/or by judicial order, the fees related to gas storage operations shall be allocated to the Mineral Owners of the Unitized Formation under the lands shown on Exhibit "A" hereto. Unit Operator agrees to pay to the Mineral Interest Owners an injection fee of $.0028 Mcf and a withdrawal fee of $.0112 per Mcf of all gas injected into the Unitized Formation that is deemed Storage Gas. Allocation of the fees of injected and withdrawn gas shall be based upon the following factors and formula: Gross Tract Pore Volume 75% Surface Acres 25% 100% Payment of the injection and withdrawal fees in excess of $25.00 shall be paid within thirty (30) days after each calendar year quarter. All accounts which represent an amount of less than $25.00 will be paid on an annual basis. In addition, Unit Operator further agrees that an annual storage fee will be paid to both the mineral owners and the non -Federal Surface Owners of the surface area under the lands shown on Exhibit "A" hereto. The annual storage fee will be $1.12 per net mineral acre, or fraction thereofldown d by the mineral owners, and a payment of $1.12 per net surface acre owned by the/SuoriaceeOwneerrs, in the Unit Area. The annual storage fees will become due and payable not later than thirty (30) days after Unit Operator first receives fees for injection of gas for storage purposes and shall be paid on or prior to the anniversary date established thereby for each year injection fees are received by the Unit Operator. Liquid hydrocarbons recovered during the processing of natural gas subsequent to the commencement of storage operations shall be considered to be Native Unitized Substances and royalties will be paid according to the formula set forth in Section 12, and allocated in accordance with Exhibit "C" of this agreement. 1 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 6I 7 1 1 2 Upon approval to conduct storage operations, no remaining native methane gas would be 2 3 deemed recoverable. When storage operations cease and all non-native gas is removed, then any gas 3 4 recovered thereafter would be deemed native and royalty will be due on the sale of that gas. 4 5 5 6 Notwithstanding anything to the contrary contained herein, for the purposes of this 6 7 agreement the owners of both the mineral and surface estates subject to this agreement shall be 7 8 compensated for the storage of gas as provided for in this Section 13. in the event a court having 8 9 jurisdiction over this matter rules to the contrary, then from that date forward allocation of gas 9 10 storage fees shall be tendered to those parties as a result of the court's ruling. No adjustment will be 10 11 made for fees paid prior to that date. 11 12 12 13 The amount of fees set out in this Section 13, shall be renegotiated with the AO at the end of 13 I4 five years from the effective date of consent, approval or certification of the Federal Energy 14 15 Regulatory Commission (FERC), or other authorizing agency. At the end of each successive five 15 16 year period that this agreement remains in effect, the amount of injection, withdrawal and storage 16 17 fees shall be renegotiated with the AO. At any point while this agreement is in effect the fees for 17 18 injection, withdrawal and storage are revised as a result of renegotiation with the AO, the Unit 18 19 Operator agrees to pay to the mineral and surface owners in accordance with this Section 13, the 19 20 newly negotiated rates or the rates then in effect, whichever is the higher. 20 2I 21 22 14. NATIVE GAS. Any remaining Native Gas will be recovered through liquid recovery 22 23 processing. Fuel usage for the operation will be calculated and/or metered and subtracted from the 23 24 remaining native methane gas on a quarterly basis. Continued cycling of native and non-native 24 25 methane gas would result in additional Natural Gas Liquids (NGL) recovery until no native methane 25 26 exists. Fuel usage for the continued cycling operation after all native gas has been recovered or used, 26 27 shall be subtracted from the non-native methane gas. The working interest owners committed hereto 27 28 shall bear all costs associated with the usage of non-native methane gas. 28 29 29 30 The value of the native gas will be deemed to be recovered proportionately in accordance 30 31 with the formula found in Section 12, and reflected on Exhibit "C" hereof. All liquefiable 3I 32 hydrocarbons recovered from the Unitized Formation shall be considered as native Unitized 32 33 Substances and shall be allocated in accordance with Exhibit "C" of this Agreement. The value 33 34 would be their proportionate share of the products sold. 34 35 35 36 Unless otherwise directed by the AO, all payments due the United States provided for herein, 36 37 shall be paid to the order of the United States Minerals Management Service, Royalty Management 37 38 Program, P. O. Box 5810, Denver, Colorado 80217-5810. 38 39 39 40 15. ROYALTY SETTLEMENT. Settlement for Royalty Interest shall be made by an 40 4I operator responsible, therefore, under existing contracts, laws, and regulations on or before the last 4I 42 day of each month for oil included within the Native Unitized Substances produced during the 42 43 preceding calendar month and on or before the last day of each month for gas included within the 43 44 Native Unitized Substances produced during the second preceding calendar month; provided, 44 45 however, that nothing herein contained shall operate to relieve the responsible parties of any land 45 46 from their respective lease obligations for the payment of any royalties due under their leases. 'ILe 46 47 oil and gas leases committed hereto as to the lands involved as well as unit or other agreements 47 48 which are affected are hereby modified to the extent that no royalties shall accrue and be payable 48 49 thereunder on any stored gas removed from the unitized formation pursuant to this Agreement. 49 50 50 51 If gas obtained from lands or formations not subject to this Agreement is introduced into the 5l 52 Unitized Formation hereunder for use in repressuring, stimulation or production, increasing ultimate 52 53 recovery or gas storage operations, which shall be in conformity with a plan first approved by the 53 54 AO, a like amount of gas less appropriate deduction for loss or depletion from any cause, may be 54 55 withdrawn from the Unitized Formation, royalty free as to dry gas, but not as to the products 55 56 extracted therefrom; provided, that such withdrawal shall be at such time as may be provided in the 56 57 approved plan of operations or as may otherwise be consented to by the AO as conforming to good 57 58 petroleum engineering practice; and provided furtshall t her that such right of withdrawal erminate on 58 59 59 the termination of this Unit Agreement. 60 60 61 61 8 1 2 3 4 5 6 7 8 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 If natural gasoline, liquid petroleum gas fractions, or other liquid hydrocarbon substances (herein collectively called "LPGS") which were not extracted from gas produced from the Unitized Formation and upon which royalty was paid at the time of production are injected in the Unitized Formation, which shall be in conformity with a plan of operation first approved by the AO, Working interest Owners shall be entitled to recover, royalty free, part or all of such LPGS pursuant to such conditions and formulas as may be prescribed or approved by the AO. Royalty due to the United States shall be computed as provided in the Federal operating regulations in 30 CFR Group 200 and paid in value or delivered in kind as to all Native Unitized Substances on the basis of the amounts hereof allocated to Unitized Federal Land as provided herein as to the rates specified in the respective Federal leases, or at such lower rates as may be authorized by law or regulation; provided, that for such leases on which the royalty rate depends on the daily average production per well, said average production shall be determined in accordance with the operating regulations as though the Unitized Lands were a single consolidated lease. As to non -Federal Lands, any royalty or other payment which varies under the terms of the instrument creating it, according to actual production from a Tract, or according to the capabilities of wells located thereof to produce, shall, on or after the effective date, be computed upon that portion of the Native Unitized Substances allocated to the particular Tract and not upon the actual production of oil and gas from the Tract or the capability of the well(s) thereon to produce. Any virgin or original oil and/or gas subsequently discovered in other formations within the Unit Area shall be produced only under the terms and conditions of the respective oil and gas leases, unit agreement, or other agreements covering such formation within the Unit Area. 16. RENTAL SETTLEMENT. Rental or minimum royalties due on leases committed hereto shall be paid by parties responsible therefore, under existing contracts, laws, and regulations, provided that nothing herein contained shall operate to relieve the responsible parties of any land from their respective lease obligations for the payment of any rental or minimum royalty in lieu thereof due under their leases. Rental and minimum royalty for lands of the United States subject to this Agreement shall be paid at the rate specified in the respective leases from the United States unless such rental or minimum royalty is waived, suspended, or reduced by law or by approval of the Secretary or his duly authorized representative. 17. CONSERVATION. Operations hereunder and production of Native Unitized Substances shall be conducted to provide for the most economical and efficient recovery of said substances without waste, as defined by or pursuant to State or Federal law or regulation. 18. DRAINAGE. The Unit Operator shall take appropriate and adequate measures to prevent drainage of Native Unitized Substances from Unitized Land by wells on land not subject to this Agreement, or with prior consent of the Authorized Officer, pursuant to applicable regulations pay a fair and reasonable compensatory royalty as determined by the Authorized officer. In the event Compensatory royalty is so paid, it shall be treated in the same manner as Unitized Substances. 19. GAUGE OF MERCHANTABLE OIL. Unit Operator shall make proper and timely gauge of all leases and other tanks within the Unit Area and associated with the operation of Unitized Land in order to ascertain the amount of merchantable oil above the pipeline connections in such tanks at 7:00 a.m. on the effective date hereof. All such oil shall be and remain the property of the parties entitled thereto the same as if the Unit has not been formed and such parties shall promptly remove said oil from said tanks. Any such oil not so removed shall be sold by Unit Operator for the account of parties entitled thereto, subject to the payment of all royalties, overriding royalties, production payments, and all other payments under the terms and provisions of the applicable lease, leases, or other contracts. All stored gas shall be measured when injected into and withdrawn from storage, and a record thereof shall be kept. Unit Operator agrees to render to the authorized officer within thirty (30) days after each calendar year quarter, a statement certified by Unit Operator showing the total amount and Btu content of gas injected into and withdrawn from said gas storage formation during that preceding calendar year quarter. The amount of gas reported as injected and withdrawn each quarter shall be computed at a standard pressure of 14.73 pounds per square inch absolute and a standard temperature of 60 degrees Fahrenheit, regardless of the pressure and temperature at which 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 9 I the gas was actually measured. The statements herein required shall be filed in duplicate with the 1 2 authorized officer. 2 3 3 4 20. LEASES AND CONTRACTS CONFORMED AND EXTENDED. The terms 4 5 and conditions, and provisions of all leases, subleases, and other contracts relating to exploration, 5 6 drilling, development, or operation for oil or gas on lands committed to this Agreement are hereby 6 7 expressly modified and amended to the extent necessary to make the same conform to the provisions 7 8 hereof, but otherwise to remain in full force and effect; and the parties hereof by this duly authorized 8 9 representative, do hereby establish, alter, change, or revoke the drilling, producing, rental, minimum 9 10 royalty, and royalty requirements of Federal leases committed hereto and the regulations in respect 10 I I thereto to conform said requirements to the provisions of this Agreement and, without limiting the 11 12 generality of the foregoing, all leases, subleases, and contracts are particularly modified in 12 13 accordance with the following: 13 14 14 15 (a) The development and operation of lands to this Agreement, under the terms hereof, 15 16 shall be deemed fill performance of all obligations for development and operation with respect to 16 17 each and every part or separately owned Tract subject to this Agreement, regardless of whether there 17 18 is any development of any particular part or Tract of the Unitized Land, notwithstanding anything to IS 19 the contrary in any lease, operating Agreement, or other contract by and between the parties hereto, 19 20 or their respective predecessors in interest, or any of them. 20 21 21 22 (h) Drilling, producing and/or gas storage operations performed hereunder upon any 22 23 tract of Unitized Land will be accepted and deemed to be performed upon and for the benefit of each 23 24 and every tract of Unitized Land, and no lease shall be deemed to expire by reason of failure to drill 24 25 or produce wells situated on the land therein embraced. 25 26 (c) Suspension of drilling or producing operations or gas storage operations on all 26 27 Unitized Land pursuant to direction or consent of the AO or his duly authorized representative shall 27 28 be deemed to constitute such suspension pursuant to such direction or consent as to each and every 28 29 Tract of Unitized Land. But, if a suspension of those operations is limited to specific lands, it shall 29 30 be applicable only to such lands. 30 31 31 32 (d) Each lease, sublease, or contract relating to the exploration, drilling, development, or 32 33 operation for oil and gas on lands committed to this Agreement which, by its terms, might expire 33 34 prior to the termination of this Agreement, is hereby extended beyond any such term so provided 34 35 therein so that it shall be continued in fill force and effect for and during the term of this Agreement. 35 36 36 37 (e) The segregation of any Federal lease committed to this Agreement is governed by the 37 38 following provision in the fourth paragraph of Section 17(m) of the Mineral Leasing Act, as amended 38 39 by the Act of September 2, 1960 (74 Stat. 781-784, 30 USC 226 m): "any (Federal) lease heretofore 39 40 or hereafter committed to any such (unit) plan embracing lands that are in part within and in part 40 41 outside of the area covered by any such plan shall be segregated into separate leases as to the lands 41 42 committed and the lands not committed as of the effective date of unitization. Provided, however, 42 43 that any such lease as to the non -unitized portion shall continue in force and effect for the terms 43 44 thereof but for not less than two years from the date of such segregation and so long thereafter as oil 44 45 and gas is produced in paying quantities." 45 46 46 47 (0 Working Interest Owners shall have the full right to use the Unitized Formation for all 47 48 necessary injection, storage and withdrawal of gas in connection with gas storage operations and 48 49 activities provided for or authorized hereunder. 49 50 50 51 21. COVENANTS RUN WITH LAND. The covenants herein shall be construed to be 51 52 covenants running with the land with respect to the interest of the parties hereto and their successors 52 53 in interest until this Agreement terminates, and any grant, transfer, or conveyance of interest in land 53 54 or leases subject hereto shall be and hereby is conditioned upon the assumption of all privileges and 54 55 obligations hereunder by the grantee, transferee, or other successors in interest. No assignment or 55 56 transfer of any Working interest shall be binding upon Unit Operator, nor shall any transfer of any 56 57 Royalty Interest or other interest be binding on the Working interest Owner responsible for payment 57 58 or settlement thereof until the first day of the calendar month after Unit Operator or the responsible 58 59 Working interest Owner, as the case may be, is furnished with the original, photostat, or certified 59 60 copy of the recorded instrument of transfer. 60 61 61 10 i 22. EFFECTIVE DATE. This Agreement shall become binding upon each party who I 2 executes or ratifies it as of the date of execution or ratification by such party and shall become 2 3 effective as of 7:00 a.m. on the first day of the calendar month next following the approval of this 3 4 Agreement by the Secretary or his duly authorized delegate. 4 5 5 6 Unit Operator shall within sixty (60) days after the effective date of this Agreement file for 6 7 record in Weld County, Colorado, a copy of this Agreement executed by the Unit Operator and a 7 8 certificate to the effect that this Agreement has become effective according to its terms and stating 8 9 further the effective date. 9 10 10 11 23. TERM. The term of this Agreement shall be for and during the time that Native I I 12 Unitized Substances can be produced in quantities sufficient to pay for the cost of producing same 12 13 from wells on Unitized Land and for as long thereafter as drilling, reworking, or other operations are 13 14 prosecuted on Unitized Land without cessation of more than sixty (60) consecutive days, and so long 14 15 thereafter as Native Unitized Substances can be produced as aforesaid, or so long as the Unitized 15 16 Formation is being utilized for the injection, withdrawal or storage of natural gas, whether or not that 16 17 natural gas is considered Native Unitized Substances, unless sooner terminated by the AO as 17 18 provided in Section 8, Successor Unit Operator, by the Working interest Owners as provided in 18 19 Section 24, Termination by Working interest Owners. 19 20 20 21 24. TERMINATION BY WORKING INTEREST OWNERS. This Agreement may 21 22 be terminated at any time by Working interest Owners owning ninety percent (90%) or more of the 22 23 participation percentage in the Unitized Land with the approval of the AO. Notice of any such 23 24 termination shall be given by the Unit Operator to all parties hereto. 24 25 25 26 Upon termination of this Agreement, the parties hereto shall be governed by the terms and 26 27 provisions of the leases and contracts affecting the separate Tracts. 27 28 28 29 If not specified otherwise by the leases unitized under this Agreement, the Basic Royalty 29 30 Owners hereby grant Working interest Owners a period of six (6) months after termination of this 30 31 Agreement in which to salvage, sell, distribute, or otherwise dispose of the personal property and 31 32 facilities used in connection with unit operations. 32 33 33 34 Unit Operator shall, within sixty (60) days after the termination of this Agreement has been 34 35 determined, pursuant to Section 8 and 24 hereof, file for record in the office or offices where a 35 36 counterpart of this Agreement is recorded, a certificate setting forth the fact of such termination and 36 37 the date thereof. 37 38 38 39 25. RATE OF PROSPECTING, DEVELOPMENT, AND PRODUCTION. The AO 39 40 is hereby vested with authority to alter or modify from time to time in his discretion the quantity and 40 41 rate of production under this Agreement when such quantity and rate of production are not fixed 41 42 pursuant to Federal or State law or does not conform to any statewide or voluntary conservation or 42 43 allocation program which is established, recognized, and generally adhered to by the majority of 43 44 operators in such state, such authority being hereby limited to alteration or modification in the public 44 45 interest, the purpose thereof and the public interest to be served thereby to be stated in the order of 45 46 alteration or modification. Without regard to the foregoing, the AO is also hereby vested with 46 47 authority to alter or modify from time to time at his discretion the rate of prospecting and 47 48 development and the quantity and rate of production wider this Agreement when such alteration or 48 49 modification is in the interest of attaining the conservation objectives stated in this Agreement and is 49 50 not in violation of any applicable Federal or State law. 50 51 SI 52 Powers in this Section vested in the AO shall only be exercised after notice to Unit Operator 52 53 and opportunity for hearing to be held not less than fifteen (15) days from notice. 53 54 54 55 26. APPEARANCES. Unit Operator shall„ after notice to other parties affected, have 55 56 the right to appear for and on behalf of any and all interests affected hereby before the Department of 56 57 Interior and to appeal from orders issued under the regulations of said Department or to apply for 57 58 relief from any of said regulations or in any proceedings relative to operations before the Department 58 59 of the interior or any other legally constituted authority; provided, however, that any other interested 59 60 party shall also have the right at his own expense to be heard in any such proceeding. 60 61 61 27. NOTICES. All notices, demands, or statements required hereunder to be given or I 2 rendered to the parties hereto shall be deemed filly given if given in writing, or personally delivered 2 3 to the party or sent by postpaid, registered, or certified mail, addressed to such party at the address 3 4 such party has furnished to the party sending the notice, demand, or statement. 4 5 5 6 28. NO WAIVER OF CERTAIN RIGiITS. Nothing in this Agreement contained shall 6 7 be construed as a waiver by any party hereto of the right to assert any legal or constitutional right or 7 8 defense as to the validity or invalidity of any law of the State of Colorado, or of the United States, or 8 9 regulations issued thereunder in any way affecting such party, or as a waiver by any such party of any 9 10 right beyond his or its authority to waive, provided, however, each party hereto except the United 10 11 States covenants that during the existence of this Agreement, such party shall not resort to any action I I 12 at law or in equity to partition the Unitized Land or the facilities used in the development or 12 13 operation thereof and to that extent waives the benefits of all laws authorizing such partition. 13 14 14 15 29. UNAVOIDABLE DELAY. All obligations under this Agreement, except the 15 16 payment of money, shall be suspended while, but only so long as Unit Operator, despite the exercise 16 17 of due care and diligence, is prevented from complying with such obligations, in whole or in part, by 17 18 strikes, acts of God, Federal, State or municipal law or agencies, unavoidable accidents, 18 19 uncontrollable delays in transportation, inability to obtain necessary material in open market, or other 19 20 matters beyond the reasonable control of the Unit Operator whether similar to matters herein 20 21 enumerated or not. 2 I 22 22 23 30. NON-DISCRIMINATION. In connection with the performance of work under this 23 24 Agreement, the Unit operator agrees to comply with all the provisions of Section 202(1) to (7) 24 25 inclusive, of Executive Order 11246, 30 CFR 12319, as amended, which are hereby incorporated by 25 26 reference in this Agreement. 26 27 27 28 31. LOSS OF TITLE. in the event title to any Tract of Unitized Land shall fail and the 28 29 true owner cannot be induced to join this Unit Agreement, such tract shall be automatically regarded 29 30 as not committed hereto and there shall be such readjustment of future costs and benefits as may be 30 31 required on account of the loss of such title. In the event of a dispute as to title as to any Royalty or 31 32 Working interest, or other interests subject hereto, payment or delivery on account thereof may be 32 33 withheld, but such funds shall be deposited as directed by the AO to be held as unearned money 33 34 pending final settlement of the title dispute, and then applied as earned or returned in accordance 34 35 with such final settlement. 35 36 36 37 Unit Operator as such is relieved from any responsibility for any defect or failure of any title 37 38 hereunder. 38 39 39 40 In order to avoid title failure which might incidentally cause the title to a Working interest or 40 41 interests to fail, the owners of (a) the surface rights to land subject to this Agreement, (b) severed 41 42 minerals or Royalty interests in said land, and (c) improvements located on said lands, but not 42 43 utilized for wait operations, shall individually, when taxed separately be responsible for the rendition 43 44 and assessment for property tax purposes of all such property, and for payment of such taxes, except 44 45 as otherwise provided in any contract or Agreement between such owners and a Working interest 45 46 Owner or in the Unit Operating Agreement. If any property taxes are not paid by such owners 46 47 responsible, therefore, when due, the Unit Operator may, at any time prior to tax sale, pay the same, 47 48 redeem such property, and discharge such tax liens as may arise through non-payment. In the event 48 49 the Unit Operator makes any such payment or redeems any such property from tax sale, the Unit 49 50 Operator shall be reimbursed, therefore, by the Working interest owners in proportion to their 50 Si respective percentages of Unit Participation; and the Unit Operator shall withhold from the proceeds 51 52 otherwise due to said delinquent taxpayer or taxpayers an amount sufficient to defray the costs of 52 53 such payment or redemption, such withholdings to be distributed among the Working interest owners 53 54 in proportion to their respective contributions toward such payment or redemption. 54 55 55 56 32.

Joinder to this Unit Agreement by a Working 2 3 interest Owner at any time must be accompanied by appropriate joinder to the Unit Operating 3 4 Agreement in order for the Interest to be regarded as committed to this Unit Agreement. Except as 4 5 may otherwise herein be provided, subsequent joinders to this Agreement shall be effective as of the 5 6 date of the filing with the AO of duly executed counterparts of all or any paper necessary to establish 6 7 commitment of any Tract to this Agreement unless objection to such joinder is made within sixty 7 8 (60) days by the AO. 8 9 9 10 33.

We are presently contacting all working, royalty and surface interest owners inviting them to commit their interest to the Unit Area, and for your consideration we are enclosing the following: 1. Copy of the Lilli Field (D -Sand) Unit Agreement with Exhibits thereto 2. Four (4) copies of the Ratification and Joinder instrument to the Lilli Field (D -Sand) Unit Agreement. We request that you review the Exhibits and advise of any discrepancies regarding your ownership in the oil, gas, or surface rights within the unit. It has been determined that gas injection into the Lilli Field would be economically advantageous, improve the efficiency of the field and recover a substantial amount of oil and gas liquids that would otherwise be unrecoverable under continued primary operations. Gas injection, or secondary recovery program, involves injecting gas into the producing formation through selected wells to supplement the natural energy of the reservoir and force oil and gas liquids trapped in the rock to the pumping units of the producing wells. This process displaces oil and gas liquids across property or lease lines which makes it necessary to unitize all properties in a way that they can be treated and operated as a single property. The working and royalty interest owners then share in the oil and gas liquids produced from the entire unit area based upon their unit participation. enc. Lilli Field (D -Sand) Unit Area page 2 Prior to approving the Lilli Field (D -Sand) Unit Agreement, the Colorado Oil and Gas Conservation Commission will review the engineering study and unit documents to determine whether the participation formula is fair and equitable and protects the rights of all owners within the unit. In the event any interested party desires to protest the application they need to file a protest under provision 508 of the Oil and Gas Conservation Act, which among other provisions requires the protest to be submitted with an original and eight copies along with a $70 docket fee. Additional information for this procedure may be obtained from the Colorado Oil and Gas Conservation Commission, 1120 Lincoln St., Suite 801, Denver, CO 80203, telephone 303-894-2100. As a royalty interest owner you will benefit from the projected increase in the amount of oil and gas liquids recovered but will not be responsible for any cost associated with the injection project. Should you have any questions regarding the unit agreement, the purpose of the unitization project, or other related matters, please contact the undersigned at the above address or telephone. You will note that the unit agreement and the ratification and joinder instruments are undated. We will insert the date after the date has been determined with the Bureau of Land Management. Please approve the unitization of the Lilli Field by signing all copies of the enclosed Ratification and Joinder Instrument before a Notary Public and return three (3) copies to Walsh Production in the enclosed self addressed stamped envelope. We would appreciate your consideration and approval of the Lilli Field (D -Sand) Unit by returning the executed ratification and joinder instrument at your earliest convenience. Sincerely, 7_47 - Jim McNay PLEASE BE SURE TO PROPERLY EXECUTE THE RATIFICATION AND JOINDER 1. IF YOU AND SOMEONE ELSE OWN THE INTEREST TOGETHER, BOTH OF YOU NEED TO SIGN. 2. IF THE INTEREST IS OWNED IN A TRUST, YOU NEED TO SIGN THE DOCUMENT AT THE TRUSTEE. 3. THE APPROPRIATE OFFICER NEEDS TO SIGN THE DOCUMENT IF THE INTEREST IS OWNED BY A CORPORATION OR PARTNERSHIP. COUNTY ATTORNEY STAFF APPROVAL This is to affirm the attached Division Order or Authorization to Receive Payment for an Oil and Gas Well has been reviewed by the County Attorney's staff as to form, legal description, and percentage of royalties, if applicable.
