l l . PARTICIPATING AREAS . At the proposal of the Unit Operator, with approval in accordance with the voting provisions of the unit operating agreement of working interest owners holding at least sixty - five percent ( 65 % ) of the net mineral acreage within the proposed area, separate Participating Areas shall be established for those pools or deposits of unitized substances, or zones thereof, that contain helium in concentrations of greater than three tenths of one percent ( . 3 % ) of the unitized substances present in such zone (the "Limit") and for those pools or deposits, or zones thereof, that contain helium in concentrations of less than or equal to the Limit . Prior to the commencement of deliveries of production of unitized substances to the Plant, the Unit Operator shall submit for approval of the Federal AO and the State AO a schedule, based on subdivisions of the public - land survey or aliquot parts thereof, of all land covered by each initial Participating Area . Each of these sets of lands shall constitute a Participating Arca upon approval of the Federal AO and the State AO, effective as of the Effective Date . The schedule shall set forth the percentage of unitized substances to be allocated, as provided in Section 12 , to each committed tract in each Participating Area so established and shall govern the allocation of production commencing with the effective date of the Participating Area . ln order to determine the percentage amount of helium present in a certain zone the zone shall be tested by the Unit Operator . The Unit Operator shall perform a seventy - two ( 72 ) hour well test of such zone, with samples from the well test stream taken every twenty - four ( 24 ) hours and measured for helium content The average of all such samples shall be deemed to be the percentage amount of helium present in the applicable zone ; provided that, if such average is above the Limit, but at least one such sample is below the Limit, Unit Operator sball conduct an additional seventy - two ( 72 ) hour well test of such zone, with samples from the well test stream taken every twenty four ( 24 ) hours and measured for helium content . If Unit Operator conducts an additional seventy - two ( 72 ) hour well test in accordance with the proviso of the preceding sentence, then the average of all samples taken over the total one - hundred and forty - four ( 144 ) hour period shall be deemed to be the percentage amount of helium present within the applicable zone . At the proposal of the Unit Operator, any two or more Participating Areas established hereunder may be combined into one, on approval of the Federal AO and the State AO and on approval in accordance with the voting provisions of the unit operating agreement of working interest owners holding at least sixty - five percent ( 65 % ) of the participating interest in each of the two Participating Areas . If it is determined that a portion of a Participating Area established for proved or probable reserves with helium in concentrations of greater than the Limit contains proved or probable reserves with helium in concentrations of less than or equal to the Limit, or that a portion of a Participating Area established for proved or probable reserves with helium in concentrations of less than or equal to the Limit contains proved or probable reserves with helium in concentrations of greater than the Limit, such portion of the Participating Area may at the proposal of Unit Operator be excluded from that Participating Area and made a separate Participating Area, or combined with another existing Participating Area, established for the appropriate helium content, on approval of the Federal AO and the State AO, and with the approval in accordance with the voting provisions of the unit operating agreement of working interest owners holding at least sixty - five percent ( 65 % ) of the participating interest in each affected Participating Area . The Participating Area or Areas may at the proposal of the Unit Operator be revised from time to time, subject to the approval of the Federal AO and the State AO and, where applicable under Section 2 , with the approval in accordance with the voting provisions of the unit operating agreement of working interest owners holding at least sixty - five percent ( 65 % ) of the participating interest in each affected Participating Area, to include additional lands then regarded as reasonably proved to contain proved or probable reserves of unitized substances from the same pool (as defined in A . R . S . 27 - 501 ) or which arc necessary for unit operations, or to exclude lands then regarded as reasonably proved not to contain proved or probable reserves of unitized substances from the same pool . The effective date of any revision shall be the first of the month in which the knowledge or information is obtained on which such revision is predicated ; provided, however, that a more appropriate effective date may be used if justified by the Unit Operator and approved by the Federal AO and the State AO . No land shall be excluded from a Participating Area on account of depletion of its unitized substances, except that any Participating Arca established under the provisions of this unit agreement shall terminate automatically whenever all completions in the formation on which the Participating Area is based are abandoned . It is the intent of this section that a Participating Area shall represent the area known or reasonably proved to contain proved or probable reserves of unitized substances with helium concentrations of greater than the Limit or with helium concentrations of less than the Limit or which are necessary for unit operations ; but, regardless of any revision of a Participating Area, nothing herein contained shall be construed as requiring any retroactive adjustment for production obtained prior to the effective date of the establishment or revision of the Participating Area . 8 DBl/63287028

In the absence of agreement at any time between the Unit Operator and the Federal AO and the State AO, as to the proper definition of, or change proposed by the Unit Operator to, a Participating Area or Areas, the portion of all payments affected thereby shall, except royalty due the United States and the State, be impounded in a manner mutually acceptable to the owners of committed working interests and the Federal AO and the State AO . Royalties due to the United States and the State shall be determined on a preliminary basis by the Federal AO for Federal lands and the State AO for the State lands and the amount thereof shall be deposited as directed by the Federal AO and the State AO until a Participating Area is finally approved and then adjusted in accordance with a determination of the sum due as Federal royalty and State royalty on the basis of such approved Participating Area . Subject to the approval rights of the Federal AO and the State AO set forth herein, any owner of unleased rights to unitized substances, and any owner of any royalty interest, overriding royalty interest or payment out of production, that has become a Party to this agreement, either directly or through subscription or consent to this agreement by a lessee who holds a power to unitize such interest, shall automatically be subject to the formation, combination, or modification of any Participating Area which is duly approved by the requisite working interest owners in accordance with this Section 11 . 12 . ALLOCATION OF PRODUCTION . All unitized substances produced from a Participating Area established under this agreement, except any part thereof used in conformity with good operating practices within the unit area for drilling, operating, and other production or development purposes, or for repressuring or recycling in accordance with a plan of development and operation that has been approved by the Federal AO and the State AO, or unavoidably lost shall be allocated to each tract within the Participating Area in proportion to the volumes of unitized substances originally in place under reservoir conditions under each tract as of the Effective Date as prescribed in the unit operating agreement (regardless of the type of unitized substance or its market value) . All unitized substances produced from within the unit area but outside of a Participating Area established under this agreement, except any part thereof used in confonnity with good operating practices within the unit area for drilling, operating, and other production or development purposes, or for repressuring or recycling in accordance with a plan of development and operation that has been approved by the Federal AO and the State AO, or unavoidably lost shall be allocated to the tract or tracts making up the drilling block for the applicable well as prescribed in the unit operating agreement (regardless of the type of unitized substance or its market value) . Tract participations in each Participating Area shall be subject to redetermination following the fifth ( 5 th) anniversary of commencement of commercial sales of unit substances from that Participating Area through the Pipeline in accordance with the procedures set forth in tl 1 e applicable unit operating agreement, effective on the first day of the calendar month following the calendar month in which those procedures are completed and subject to the approval of the Federal AO and the State AO . There will be no other redetermination of tract participations, except as provided for in the following paragraph . In the event any tract is added to or excluded from a Participating Area as provided in Sections 2, 11, 27, 28 or 30, the tract participations shall be redetermined, effective as of the date of addition or exclusion, as follows: (a) In the case of the exclusion of a tract, the remaining tract participations shall be increased proportionately so that they again total 100 % ; or (b) In the case of the addition of a tract, the volumes of unitized substances originally in place under reservoir conditions in the added tract shall be determined in the same manner as provided for an initial determination of tract participations in the unit operating agreement, and then, using that volume so detennined and the volumes then in effect for the existing tracts in the Participating Area, the tract participations shall again be calculated by dividing each tract's volume of unitized substances originally in place under reservoir conditions by the total volume of unitized substances originally in place under reservoir conditions in the entire Participating Area . With respect to settlement of royalty, overriding royalty and payment out of production obligations of the respective working interest owners, there shall be no retroactive adjustment for production obtained prior to the effective date of the redetermination, but instead such obligations shall be calculated from that point forward based on the increased or reduced quantities of unitized substances (including any make - up quantities) allocated to each tract 9 DBl/63287028

Following any redetermination of tract participations, the Unit Operator shall distribute to all Parties, the Federal AO and the State AO a new schedule showing tract participations for the Participating Area . There shall be allocated to th e working interest owner(s) of each tract of unitized land in each Participating Area, in addition, tha t interest in uni t production that would be attributable to any unlcased right s to unitized substance s within that Participating Are a based upon th e calculations provided herein, if such unitized substance rights wer e leased, subjec t to the compensatory royalty obligations specified in Section 17 of thi s agreement . Allocation of production hereunder for purposes other than for settlement of th e royalty, overriding royalty, or paymen t out of production obligation s of th e respective working interest owners, including compensatory royalty obligation s under Section I 7 , shal l be prescribed as set forth in the uni t operating agreemen t or as otherwise mutually agreed by the affected Parties . Each working interest owner shall have the right and obligation to take in kind and separately dispose of its allocated share of unitized substances, and shall have the right to construct, maintain and operate within the unit area, at its sole risk . cost and expense, all facilities required for that purpose, provided they arc constructed, maintained and operated so as not to interfere with unit operations . Each Party's share of unitized substances shall be delivered at the outlet flange of the Plant . If any Party fails to take in kind or separately dispose of such party's share of unitized substances, Unit Operator shall have the right, but not the obligation, subject to revocation by notice by the Party owning the share, to purchase such share or sell such share to others, provided, however, that the effective date of such revocation notice may be deferred at Unit Operator's election for a period not to exceed ninety ( 90 ) days if Unit Operator has committed some or all of such share to a purchase contract . The proceeds from the unitized substances so disposed of by Unit Operator shall be paid to the working interest owners of each affected tract who shall pay the burdens thereon and distribute such proceeds to the persons entitled thereto . Any purchase or sale by Unit Operator of any other working interest owner's share of unitized substances shall be only for such reasonable periods of time as are consistent wtth the minimum needs of the industry under the particular circumstances, but in no event for a period in excess of one (I) year . Any sale by Unit Operator on behalf of another Party under this Section shall be in a manner commercially reasonable under the circumstances, but Unit Operator shall have no duty to share any existing market or contract or to obtain a price or transportation fee equal to that received by Unit Operator . Any purchase by Unit Operator or any of its affiliates from another Party under this Section shall be at the prevailing market price for sales from the unit area agreed at the same time and shall be in compliance with all legal obligations applicable to production purchasers . Unitized substances allocated to each tract pursuant to this agreement shall be considered production from that tract for all purposes, including payment of royalties and calculation of severance truces . It is hereby agreed that production of unitized substances from a Participating Area shall be allocated as provided herein, for royalty and other purposes, regardless or whether any wells are drilled on any particular part or tract of the Participating Area . If any unitized substances produced from one Participating Area are used for repressuring or recycling purposes or otherwise for purposes of unit operations in another Participating Area, the first of that type of unitized substances withdrawn from the latter Participating Area for sale during the life of this agreement shall be considered to be the unitized substances so transferred, until an amount equal to that transferred shall be so produced for sale and such unitized substances shall be allocated to the Participating Area from which initially produced as such area was defined at the time that such transferred unitized substances were finally produced and sold . Such withdrawn unitized substances shall be free of royalties if royalty was paid on such volumes upon production from the original Participating Area pursuant to Section 14 . Unitized substances which have, in the case of liquids, been lifted from the tanks prior to the Effective Date and, in the case of gas, passed the intake or sales meter of the purchaser or receiving pipeline in (or in the vicinity of) the unit area prior to the Effective Date of this agreement shall not be allocated under this agreement and shall remain the property of the persons entitled thereto prior to the Effective Date, and such persons shall be entitled to receive all proceeds thereof and shall be responsible for the payment of all royalties, overriding royalties, production payments, production truces and all other payments chargeable against or payable out of such unitized substances . 13 . DEVELOPMENT OR OPERATION OF NON - PARTICIPATING LAND OR FORMATIONS . Any Party owning or controlling the working interest in any unitized land having thereon a regular well location may, at such party's sole risk, costs, and expense, drill a well to test any formation provided the well is outside any Participating Area established for that formation, unless within ninety ( 90 ) days of receipt of notice from said Party of his DBl/63287028

intention to drill the well, the Unit Operator elects and commences to drill the well in a like manner as other wells are drilled by the Unit Operator under this agreement . If any well drilled under this section by a working interest owner results in production of unitized substances in paying quantities such that the land upon which it is situated may properly be included in a Participating Area, then, subject to the requirements of Sections 2 and 11 hereof, such Participating Area shall be established or enlarged as provided in this agreement and the well shall thereafter be operated by the Unit Operator in accordance with tl 1 e terms of this agreement and the unit operating agreement . If any well drilled under this section by a working interest owner obtains production in quantities that do not clearly meet the standards in the previous paragraph for inclusion of the land upon which such well is situated in a Participating Area, such well may be operated and produced by the Party drilling the same, subject to the consetvation requirements of this agreement . The royalties in amount or value of production from any such well shall be paid as specified in tlle underlying lease and agreements affected . 14 . ROYALTY SETTLEMENT . The United States and the State and any royalty owner who is entitled under his lease to take in kind a share of the substances now unitized hereunder shall hereafter be entitled to the right to take in kind its share of the unitized substances, and Unit Operator, or the working interest owner in case of the operation of a well by a working interest owner as provided in Section 13 or otherwise herein, shall make deliveries of such royalty share taken in kind, in conformity with the applicable contracts, laws, and regulations, at the outlet flange of the Plant (referred to herein as the "delivery point") . The working interest owners receiving in kind or separately disposing of all or part of the unitized substances allocated to any tract (except Unit Operator when disposing of another working interest owner's share pursuant to Section 12 ) shall be responsible for payment of all royalties, overriding royalties and other payments out of production not taken in kind with respect to such tract . Settlement for royalty interest not taken in kind shall be made by working interest owners responsible therefor as provided under the applicable lease or, if not so provided, on or before the last day of each month for unitized substances produced during the preceding calendar month . In the event that the State or a private royalty owner elects to lake its royalty share in kind and in the event tllat the applicable royalty owner elects to transport such royalty share through the Pipeline, or to use other infrastructure downstream of the delivery point, such royalty interest owner shall reimburse the applicable working interest owners the actual cost of such transportation, compression, storage or other infrastructure use, including the royalty interest owner's proportionate share, based on throughput as dcscnbed below in fuis Section, of any cost of capital incurred by such working interest owners related to the construction of the Pipeline or such other infrastructure . Royalty owners grant working interest owners the right to inject gas, water or other substances from the unit area into the unit area for pwposes of unit operations, together with a right to drill, use and maintain injection wells in the unit area, provided that no anthropogenic (man made) carbon dioxide may be injected into the unit area without the prior consent of the Federal AO and the State AO . Royalty owners further grant to working interest owners the right to take over and use for production or injection purposes existing wells or dry holes in the unit area . No royalty shall be payable on unitized substances obtained from any Participating Area if reinjected in the Participating Area . Gas (other than anthropogenic carbon dioxide}, water and other substances obtained from lands not subject to this agreement may be introduced into any Participating Area hereunder, but only for use in repressuring, stimulation of production, or increasing ultimate recovery in conformity with a plan of development and operation approved by tlle Federal AO and the State AO, in which case in the case of gas a like amount of that type of gas, after settlement as herein provided for any unitized substance transferred from any other Participating Area and witll appropriate deduction for loss from any cause, may be withdrawn from the formation into which such gas was introduced, royalty free as to dry gas, but not as to any products which may be extracted therefrom ; provided that the first gas of that type withdrawn shall be considered to be tlle gas so transferred, unless ofuerwise provided in the approved plan of development and operation or as may otherwise be consented to by the Federal AO and the State AO as conforming to good petroleum engineering practice ; and provided further, that such right of withdrawal shall terminate on the tennination of this unit agreement . 11 DBl/63287028

Royalty due the United States shall be computed as provided in 30 C . F . R . Group 200 and paid in value or delivered in kind as to all unitized substances on the basis of the amounts thereof allocated to unitized Federal land as provided in Section 12 at the rates specified in the respective Federal lease, or at such other rate or rates as may be authorized by law or regulation and approved by the Federal AO ; provided, that for 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 each Participating Area were a single consolidated lease . This paragraph does not apply to State unitized substances acquired from the United States and initially leased by a federal agency . Royalty due on account of State lands shall be computed and paid on the basis of all unitized substances allocated to such lands . The royalties paid upon helium allocated to each tract shall be based upon (i) if sold other titan to an affiliate of the applicable working interest owner, the value actually obtained for such helium, free of any costs of production and market preparation, including but not limited to compression, dehydration and gathering, prior to the delivery point of the royalty share as specified in this Section, but net of all costs of compression, transportation, storage and marketing, and costs of liquefaction, if liquefied, on such royalty share incurred from and after such delivery point through such point of sale or (ii) if sold to any affiliate of the applicable working interest owner, the market value at the delivery point of the royalty share . It is recognized by the Parties that there are few arm's length sales for carbon dioxide gas . It is further recognized by the Parties that it is the responsibility of the working interest owners to place carbon dioxide gas in a marketable condition, free of cost to the royalty owners . Therefore, the Parties agree that, as further consideration for entering into this agreement, royalties paid upon carbon dioxide allocated to each tract shall be based upon the greatest of the following : (a) (i) if sold other than to an affiliate of the applicable working interest owner, the value actually obtained for such carbon dioxide, free of any costs of production and market preparation, including but not limited to compression, dehydration, and gathering, prior to the delivery point of the royalty share as specified in this Section, but net of all costs of compression, transportation, storage and marketing on such royalty share incurred from and after such delivery point through such point of sale or (ii) if sold to any affiliate of the applicable working interest owner, the market value at the delivery point of the royalty share ; (b) A minimum value for carbon dioxide of fifty cents per thousand cubic feet ( $ 0 . 50 /MCF) . At the beginning of the calendar year after first delivery carbon dioxide gas from the unit area is made, and each year thereafter, said value shall be adjusted in accordance with the annual rate of change in the Oil and Gas Extraction Index (or the successor index thereto) published by the Bureau of Labor Statistics of the United States Department of Commerce for the prior calendar year, or, if such Index ceases to be published and there is no successor index, a reasonably equivalent index published by an authoritative third party that Unit Operator reasonably designates and is approved by the State AO, such consent not to be unreasonably withhold . However, no adjustment below fifty cents per thousand cubic feet ( $ 0 . 50 /MCF) shall ever be made ; or (c) In no case shall (i) the royalties paid under this agreement for any calendar year after the first commercial delivery of carbon dioxide gas from the unit area is made be less than (ii) the annual rentals or minimum royalties paid for the calendar year preceding the calendar year during which the first commercial delivery of carbon dioxide gas from the unit area occWTed . In the case whore amount (i) is less than amount (ii) for any year, an appropriate retroactive payment shall be made in an amount equal to the difference between the amount that would have been paid for such year in accordance with subpart (ii) of this paragraph and the amount actually paid for such year in accordance with subpart (i) of this paragraph . Where the cost of capital incurred by a working interest owner or its affiliates downstream of the delivery point is to be deducted or recovered, deduction or recovery shall be accomplished over time by dividing the total capital cost by the forecast quantities of unitized substances to be produced from the Participating Areas for the first twenty years of commercial production, as approved by the working interest owners in accordance with the voting provisions of the unit operating agreement, to obtain a capital recovery charge per unit of production . That charge shall then be applied against all production using the relevant facilities until the applicable capital costs have been fully deducted or recovered . 12 DB1/63287028

15. RENTAL SETTLEMENT . Rental or minimum royalties due on leases committed hereto shall be paid by appropriate working interest owners under existing contracts, laws, and regulations, provided that nothing herein contained shall operate to relieve the lessees of any land from their respective lease obligations for the payment of any rental or minimum royalty due under their leases . Rental or minimum royalty for lands subject to this agreement shall be paid at the rate specified in the respective leases or, in the case of minimum royalty, the rate specified in Section 14 , if higher, unless such rental or minimum royalty is waived, suspended, or reduced by law or by approval of the Secretary or his duly authorized representative, as to Federal leases, or the State AO, as to State leases, or the private royalty owner, as to private leases . Unitized substances expected to be produced from the unit area cannot be marketed until the Plant and Pipeline can be built, and sales and delivery of carbon dioxide gas to such facilities will not begin until some time after the Effective Date hereof . Therefore, as part of the consideration for the execution of this agreement, the working interest owners will pay to each royalty owner whose interest under a lease has been committed to this agreement, and each such royalty owner will hereby accept, for each year until the earliest of : (i) the commencement of commercial sales of unitized substances from a Participating Area containing all or a part of the tract(s) covered by the applicable lease, (ii) exclusion of such tract(s) from the unit area, or (iii) release of such tract(s), a rental payment equal to the shut - in royalty payable to that royalty owner in accordance with the tenns of its lease, provided that, in the case of State leases, the compensatory rental shall be paid at a rate equivalent to the shut - in royalty payable in accordance with the terms of the lease and applicable statutes and regulations (including, without limitation, A . R . S . 27 - 555 . 01 ) or, if a rate is not so specified for a particular year, three dollars per acre for each such year . This special compensatory rental shall be payable in advance on or before 30 days after the Effective Date and annually thereafter on each anniversary of the Effective Date . The compensatory rental requirement stated in this paragraph shall be in lieu of, and shall not be in addition to, any shut - in royalty payment requirements of the leases and the satisfaction of the compensatory rental payment requirements stated in this paragraph shall serve to maintain the leases . With respect to any lease on non - federal land containing provisions which would terminate such lease unless drilling operations are commenced upon the land covered thereby within the time therein specified or rentals are paid for the privilege of deferring such drilling operations, the rentals required hereby shall, notwithstanding any provision of such lease, be deemed to accrue and become payable during the term as extended by this agreement in lieu of the rentals required thereby until : (i) the required drilling operations are commenced upon the land covered thereby, (ii) some portion of such land is included within a Participating Area, or (iii) such land is excluded from the unit area or such lease is released . 16. CONSERVATION . Operations hereunder and production of 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 . 17. DRAINAGE . (a) The Unit Operator shall take such measures as the Federal AO and the State AO deems appropriate and adequate to prevent drainage of unitized substances from unitized land by wells on land not subject to this agreement, which shall include the drilling of protective wells and which may include the payment of a fair and reasonable compensatory royalty, as determined by the Federal AO, as to Federal leases, and the State AO, as to State leases . (b) Whenever a Participating Area approved under Section 11 of this agreement contains unleased Federal lands, the value of 12 ½ percent of the production that would be allocated to such Federal lands under Section 12 of this agreement, if such lands were leased, committed, and entitled to participation, shall be payable as compensatory royalties to the Federal Government . Parties to this agreement holding working interests in committed leases within the applicable Participating Area shall be responsible for such compensatory royalty payment on the volume of production reallocated from the unleased Federal lands to their unitized tracts under Section 12 . The value of such production subject to the payment of said royalties shall be determined pursuant to 30 C . F . R . Part 206 . Payment of compensatory royalties on the production reallocated from unleased Federal land to the committed tracts within the Participating Area shall fulfill the Federal royalty obligation for such production, and said production shall be subject to no further royalty assessment under Section 14 of this agreement . Payment of compensatory royalties as provided herein shall accrue from the date the committed tracts in the Participating Area that includes unleased Federal lands receive a production allocation, and shall be due and payable monthly by the 13 DBl/63287028

last day of the calendar month next following the calendar month of actual production . If leased Federal lands receiving a production allocation from the Participating Area become unleased, compensatory royalties shall accrue from the date the Federal lands become unleased . Payment due under this provision shall end when the unleased Federal tract is leased, when the affected lands are excluded from the unit area, or when production of unitized substances ceases within the Participating Area and the Participating Area is terminated, whichever occurs first (c) Whenever a Participating Area approved under Section 11 of this agreement contains unleased rights to unitized substances, other than Federal lands, which have been committed to this agreement by the applicable owner of such rights, those lands shall be treated in the same manner as Federal lands pursuant to Section 17 (b) unless and until the fee owner or owners lease the lands or drill a well and commence production of unitized substances, subject to this agreement and the unit operating agreement . 18. LEASES AND CONTRACTS CONFORMED AND EXTENDED . As of the Effective Date, the terms, conditions, and provisions of all leases, subleases, rights - of - way and other contracts relating to exploration, drilling, development, or operation for unitized substances on lands committed to this agreement are hereby expressly modified and amended to the extent necessary to make the same conform to the provisions hereof, but otherwise to remain in full force and effect ; and the Parties hereby consent that the Secretary, as to Federal leases, and the Land Commissioner, as to State leases, each by his approval hereof, or by the approval hereof by his duly authorized representative, shall and does hereby establish, alter, change, or revoke the drilling, producing, rental minimum royalty, and royalty requirements of Federal and State leases committed hereto and the regulations in respect thereto to conform said requirements to the provisions of this agreement, and, without limiting the generality of the foregoing, all leases, subleases, and contracts are particularly modified in accordance with the following : (a) The development and operation of lands subject to this agreement under the terms hereof shaJI be deemed full performance of all obligations for development and operation with respect to each and every separately owned tract subject to this agreement, regardless of whether there is any development of any particular tract of this unit area . (b) Drilling and producing operations perfonned hereunder upon any tract of unitized lands will be accepted and deemed to be performed upon and for the benefit of each and every tract of unitized land, and no lease (or segregated portion thereof pursuant to Sections 18 ( £ ) and 18 (g)) shall be deemed to expire by reason of failure to drill or produce wells situated on the land therein embraced . (c) Suspension of drilling or producing operations on all unitized lands pursuant to direction or consent of the Federal AO and the State AO, shall be deemed to constitute such suspension pursuant to such direction or consent as to each and every tract of unitized land . A suspension of drilling or producing operations limited to specified lands shall be applicable only to such lands . (d) Each lease, sublease and right - of - way and other agreements with royalty owners relating to the exploration, drilling, development, or operation for unitized substances on lands other than those of the United States committed to this agreement which, by its terms might expire prior to the termination of this agreement, is hereby extended beyond any such tenns so provided therein so that it shall be continued in full force and effect for and during the term of this agreement {subject, in the case of State leases, to Section 18 (g)} . (e) Any Federal lease committed hereto shall continue in force beyond the term so provided therein or by law as to the land committed so long as such lease remains subject hereto, provided that production of unitized substances in paying quantities is established under this unit agreement prior to the expiration date of the term of such lease, or in the event actual drilling operations are commenced on unitized land, in accordance with provisions of this agreement, prior to the end of the primary term of such lease and are being diligently prosecuted at that time, such lease shall be extended for two years, and so long thereafter as unitized substances are produced in paying quantities in accordance with the provisions of the Mineral Leasing Act, as amended . (f) The segregation of any Federal lease committed to this agreement is governed by the following provision in the fourth paragraph of Section 17 G) of the Mineral Leasing Act, as amended by the Act of September 1 , 1960 , { 74 Stat . 781 - 784 ) ( 30 U . S . C . 226 (m)) : "Any (Federal) lease heretofore or hereafter committed to any such (Unit) plan embracing lands that are in part within and in part outside the area covered by any such plan 14 DBl/63287028

shall be segregated into separate leases as to the lands committed and the lands not committed as of the effective date of unitization . Proyjded, however, that any such lease as to non - unitized portion shall continue in force and effect for the tenn thereof, but for not less than two years from the date of such segregation and so long thereafter as oil or gas is produced in paying quantities . " (g) Any lease embracing lands of the State having only a portion of its lands committed hereto, shall be segregated as to the portion committed and the portion not committed, and the terms of such lease shall apply separately to such segregated portions commencing as of the Effective Date hereof ; provided, however, that notwithstanding any of the provisions of this agreement to the contrary, any such lease, as to the non - unitized portion, shall continue in full force and effect for a period of time equal to the greater of the original term of the lease or two years from the date of such segregation and for so long thereafter as there is production in paying quantities from or attributable to such non - unitized portion of such lease . 19. COVENANTS RUN WITH LAND . The covenants herein shall be construed to be covenants running with the land with respect to the interests of the Parties and their successors in interest until this agreement terminates, and any grant, transfer or conveyance of interest in land or lease subject hereto shall be and hereby is conditioned upon the assumption of all privileges and obligations hereunder by the grantee, transferee, or other successor in interest . No assignment or transfer of any working interest, royalty, or other interest subject hereto shall be binding upon Unit Operator or any other working interest owner until the first day of the calendar month after Unit Operator is furnished with the original, photostatic, or certified copy of the instrument of transfer . 20. EFFECTIVE DATE AND TERM . Subject to approval by the Federal AO and the State AO or tl 1 eir duly authorized representatives, this agreement shall become effective as of February 1 , 2009 (the "Effective Date"), and shall remain in effect for five ( 5 ) years from the Effective Date and so long thereafter as unitized substances can be produced in quantities sufficient to pay for the cost of producing same from wells on unitized land within any Participating Area established hereunder . Should production cease after the initial five - year term for reasons other than force majeure (as that term is defined in Section 25 ) and diligent drilling, completion or reworking operations to restore production or establish new production are not in progress within sixty ( 60 ) days, or should such operations cease for more than sixty ( 60 ) consecutive days for reasons other than force majeure, and production is not restored or new production is not obtained in paying quantities on committed lands within this unit area, this agreement will automatically tenninate effective the last day of the month in which the last unitized production occurred . Notwithstanding the preceding, this agreement shall terminate: (a) Ninety ( 90 ) days after notice by the State AO, given at any time on or after the first anniversary of the Effective Date, if by such first anniversary the work program agreed in Section 9 has not been completed or waived in writing by the State AO, and Unit Operator fails to complete such work program wiiliin such ninety ( 90 ) day notice period (or such longer period as may be agreed by the State AO) ; (b) Ninety ( 90 ) days after notice by the State AO, given at any time on or after the fifth ( 5 th) anniversary of the Effective Date, if by such fifth anniversary, substantially all tlle elements of tlle plan of development and operation approved by the Federal AO and the State AO pursuant to Section IO that arc to be completed prior to that date have not been completed or waived in writing by ilie State AO, and Unit Operator fails to complete such work program witllin such ninety ( 90 ) day notice period (or such longer period as may be agreed by the State AO) ; (c) Ninety ( 90 ) days after notice by the State AO, given at any time on or after tlle fifth ( 5 th) anniversary of tlle Effective Date, if by such fifth ( 5 th) anniversary the Plant and the Pipeline have not been constructed and commissioned ; or (d) Upon voluntary dissolution of the unit approved in accordance with the voting provisions of ilie unit operating agreement by working interest owners holding at least sixty - five percent ( 65 % ) of the net mineral acreage in the unit, such approval to be evidenced in writing . The Unit Operator shall give notice of any such approval to all Parties . 15 DBl/63287028

Upon termination of this agreement, the further development and operation of the Participating Areas as a unit shall be abandoned and uni t operations shall cease . Each lease and other agreement covering lands within the uni t area shal l remain in force for two ( 2 ) years after th e date on which thi s agreemen t terminates as if there were production in paying quantitie s fro m or attributable to each such lease and for such further period, if any, as is provided by th e terms of the lease or other contract, except for (i) Stat e leases, which shall, subject to Article X, Section 3 of the Constitution of th e State of Arizona, continu e in effec t for a period of tim e equa l to the greater of the remainder of the original term of the leas e or two years after the dat e on which this agreemen t terminates and for so long thereafter as ther e is production in paying quantities from or attributabl e to such leas e and (ii) Federa l leases, which shall, subjec t to 43 C . F . R . † 3 l 83 . 4 (b), continue in effec t for a period of tim e equa l to th e greater of the remainder of th e origina l ter m of the leas e or two years after the dat e on which this agreement terminates, and for so long thereafter as ther e is production in paying quantities from or attributable to such lease . If not otherwise granted by th e leases or other instruments affecting each tract, royalty owners hereby grant working interest owners a period of ninety ( 90 ) day s after th e date of termination of this agreement within which to salvag e and remov e unit equipment . 21. ADJUSTMENTS DURING APPROVAL PERIOD . The Parties recognize that, notwithstanding the Effective Date, expenditures will not actually be borne, and production will not actually be shared, on the basis set forth herein until this agreement has been approved by the State AO and the Federal AO . All expenditures incurred by the Unit Operator with respect to the unit area or with respect to unit operations during the period (the "Approval Period") prior to the date upon which this agreement has been approved by the State AO and the Federal AO or their duly authorized representatives (the "Approval Date") but after the Effective Date shall be considered to be expenditures for the unit account for all pwposes of this agreement and the unit operating agreement For die purpose of the preceding sentence, the word "incurred" shall be interpreted in accordance with generally accepted accounting principles and the Unit Operator's historic accounting recognition practices . Within thirty ( 30 ) days after the Approval Date, the Unit Operator shall issue to each working interest owner a schedule showing each Party's actual share of expenditures incurred during the Approval Period, the share that each such Party would have borne, had it paid its share of such expenditures, calculated on the basis of net mineral acres held by each such Party in the unit, in accordance with the tenns of the unit operating agreement, and the amount owing by or to each such Party . Each Party owing an aggregate underpayment shall pay that amount to the Unit Operator, and upon receipt of any such amounts the Unit Operator shall promptly pay the amounts owed to the Parties that have made an aggregate overpayment in proportion to the aggregate overpayment by each . Each Party owing any amount pursuant to this paragraph shall pay that amount in full at the end of the calendar month following the calendar month in which the Unit Operator delivers its schedule under this paragraph . Should any Party owing any amount pursuant to this paragraph fail to pay that amount when due, no other Party shall be obligated to contnbute the amounts in default, but all other rights and remedies referenced in Section 7 shall apply with respect to such default . Production of unitized substances from the unitized land during the Approval Period shall be considered part of each working interest owner's production for all purposes of this agreement . Adjustments to the unitized substances produced from the unitized land during the Approval Period shall be made as follows : Within thirty ( 30 ) Days of the Approval Date, the Unit Operator shall furnish each working interest owner with a statement showing : (a) the aggregate quantities of each type of unitized substance allocated to each tract during the Approval Period ; (b) the quantities of each type of unitized substance which each tract should have been allocated during the Approval Period, calculated on the basis of net mineral acres in each tract, in accordance with the tenns of the unit operating agreement ; and (c) the amount of each tract's aggregate net swplusage or net deficiency of each type of unitized substances based upon the difference between (A) the aggregate quantities of each type of unitized substances allocated to each tract during the Approval Period and (B) the aggregate quantities which each tract should have been allocated within the Approval Period in accordance with the net mineral acres in each tract in the unit, as determined in accordance with paragraphs (a) and (b) above (the aggregate surplusage or deficiency shall be referred to as the "Adjustment Quantity" with respect to each tract for each type ofunitized substance sold separately) . 16 DB 1/63287028

Each tract entitled to an Adjustment Quantity (a "Dejicie 11 cy Tract'') shall be allocated, beginning from the first day of the second calendar month following the date upon which the Unit Operator furnishes the statement containing the Adjustment Quantities to all of the working interest owners (the "Adjustment Date") . an additional share of production of each type of unitized substances with respect to which they have an Adjustment Quantity, which share shall be subtracted from the quantity of such type of unitized substance which the tracts with a net surplusage as described in paragraph (c) above (the "Surplusage Tracts") would otherwise have been allocated, until the Adjustment Quantity has been made up . The additional share to which each Deficiency Tract is entitled shall be its pro rata share, in the proportion that its Adjustment Quantity bears to the total Adjustment Quantities for that unitized substance, of fifty percent ( 50 % ) of the production of that type of unitized substance to which the Surplusage Tracts would otherwise be allocated following the Adjustment Date . The share of the Adjustment Quantity for each unitized substance that each Surplusage Tract must bear shall be the proportion that each such tract's overproduction of that type of unitized substance bears to the overproduction of that type of unitized substance by all Surplusage Tracts . If necessary to facilitate this adjustment, the Parties holding interests in the Deficiency Tracts shall be temporarily assigned, and shall temporarily assume, an interest in each contract for the sale of unitized substances held by the Parties holding interests in the Surplusage Tracts, sufficient to permit each of the Parties holding interests in the Deficiency Tracts to receive the full percentage of the Adjustment Quantity allocation of unitized substances covered by each such sales contract to which it is entitled under this Section . Such assignment shall be effective as of the Approval Date . Each Party shall cooperate to obtain any approvals needed from the production purchasers and processors and shall execute such instruments and take such actions as shall be reasonably required to accomplish such assignment (and, if applicable, novate the Parties from the Deficiency Tract into the sales contracts) . No compensation shall be paid to any affected Party for past variations in the price of unitized substances. The adjustments for unitized substances during the Approval Period descnoed in this Section shall not result in a retroactive adjustment of amounts previously delivered to the owners of royalty interests, overriding royalty interests or payments out of production with respect to those interests, but instead the adjustments to unitized substances delivered pursuant to this Section shall be taken into account for purposes of detennining such interests as increases or reductions in production received by each working interest owner in the calendar month in which such increases or reductions in allocations of unitized substances are actually implemented . 22. APPEARANCES . Unit Operator shall, after notice to other Parties affected, have the right to appear for and on behalf of any and all interests affected hereby before the Department of the Interior, the Land Commissioner and the Commission, and to appeal from orders issued under the regulations of said Department, Land Commissioner or Commission or to apply for relief from any of said regulations, or in any proceedings relative to operations before the Department, the Land Commissioner or the Commission or any other legally constituted authority ; provided, however, that any other interested Party shall also hove the right at its own expense to be heard in any such proceeding . 23. NOTICES . All notices, demands, or statements required hereunder to be given or rendered to the Parties shall be in writing and shall be personally delivered to the Party or Parties, or sent by postpaid registered or certified mail, to the last known address of the Party or Parties . 24. NO WAIYER OF CERTAlN RIGHTS . Nothing contained in this agreement shall be construed as a waiver by any Party of the right to assert any legal or constitutional right or defense as to the validity or invalidity of any law of the State or of the United States, or regulations issued thereunder in any way affecting such party, or as a waiver by any such Party of any right beyond his or its authority to waive . 25. UNAVOIDABLE DELAY . All obligations under this agreement requiring the Unit Operator to commence or continue drilling, or to operate on, or produce unitized substances from any of the lands covered by this agreement, shall be suspended while the Unit Operator, despite the exercise of due care and diligence, is prevented from complying with such obligations, in whole or in part, by strikes, acts of God, Federal law or agencies, any state law or agencies, any municipal law or agencies, unavoidable accidents, uncontrollable delays in transportation, inability to obtain necessary materials or equipment in open market, or other matters beyond the reasonable control 17 DBl/63287028

of the Unit Operator whether similar to matters herein enumerated or not (all such matters shall be referred to herein as "force majeure") . Financial difficulty, insufficient funds, and failure to pay money shall not qualify as events of force majeure . 26. NONDISCRIMINATION . In connection with the performance of work under this agreement, the Unit Operator agrees to comply with all provisions in Section 202 ( 1 ) to ( 7 ) inclusive, of Executive Order 11246 ( 30 C . F . R . 12319 ), as amended, which are hereby incorporated by reference in this agreement . 27. LOSS OF TITLE . In the event title to any working interest or unleased rights to unitized substances in any tract of unitized land shall fail and the true owner cannot be induced to join in this unit agreement, such tract shall be automatically regarded as not committed hereto, and there shall be a redetermination of tract participations as may be required on account of the loss of such title . In the event title to any royalty interest, overriding royalty interest or other payment out of production with respect to any tract of unitized land shall fail and the true owner cannot be induced to join this unit agreement, the provisions of Section 28 (c) shall apply . In the event of a dispute as to title to any royalty, working interest, or other interests subject hereto, payment or delivery on account thereof may be withheld without liability for interest until the dispute is finally settled ; provided, that, as to Federal and State lands or leases, no payments of funds due the United States or the State should be withheld, but such funds due the United States shall be deposited as directed by the Federal AO and such funds due the State shall be deposited as directed by the State AO, to be held as unearned money pending final settlement of the title dispute, and then applied as earned or returned in accordance with such final settlement . Unit Operator as such is relieved from any responsibility for any defect or failure of any title hereunder, except in respect of working interests owned by Unit Operator, in which case Unit Operator will be treated as any other working interest owner . 28. NON - JOINDER AND SUBSEQUENT JOINDER . (a) If the owner of any royalty or other non - working interest in a tract within the unit area fails or refuses to subscribe or consent to this agreement, the owner of the working interest in that tract may withdraw the tract from this agreement by written notice delivered to the proper Bureau of Land Management office, the Land Commissioner and the Unit Operator prior to the approval of this agreement by the Federal AO and State AO . Upon any such withdrawal, there shall be a redetermination of tract participations as may be required on account of such withdrawal . (b) Prior to the approval of this agreement by the Federal AO and the State AO or their authorized representatives, any gas interests in lands within the exterior outline of the unit area shown on Exhibit "A" that are not committed hereto may be committed hereto by the owner or owners thereof subscribing or consenting to this agreement, and, if the interest is a working interest, by the owner of such interest subscribing to the unit operating agreement, without a requirement for approval by the working interest owners in the existing unit area, provided that all working interests and unleased gas rights within a tract must be committed hereto or that tract may not be included in the unit area (nor interests therein committed to this agreement) . After such federal and state approvals, the right of subsequent joinder, as provided in this section, by a working interest owner or owner of unleased gas rights is subject to the approval provided for in Section 2 (d) and, in the case of a working interest owner, such requirements, if any, pertaining to such joinder, as may be provided for in the unit operating agreement After such federal and state approvals, joinder by a non - working interest owner must be consented to in writing by the working interest owner committed hereto and responsible for the payment of any benefits that may accrue hereunder on behalf of such non - working interest . A non - working interest may not be committed to this unit agreement unless the corresponding working interest is committed hereto . Joinder to the unit agreement by a working interest owner, at any time, must be accompanied by appropriate joinder to the unit operating agreement, in order for the interest to be regarded as committed to this agreement . Except as may otherwise herein be provided, subsequent joinders to this agreement shall be effective as of the last date of the filing with the Unit Operator, the Federal AO and the State AO of duly executed counterparts of all or any papers necessary to establish effective commitment of any interest and/or tract to this agreement . Upon any such commitment or joinder, there shall be a redetermination of tract participations as may be required on account of such additional tract . (c) While any royalty interest, overriding royalty interest or other non - working interest in leased lands in the unit area is not committed to the unit, that interest shall be accounted for by the working interest owners responsible therefor as if this agreement were not in effect and no unit had been formed . 18 DBl/63287028

(d} In the event that previously unleased rights to unitized substances that have been committed to the unit are leased, and the working interest owner joins this agreement and the unit operating agreement in conformance with the requirements hereof and thereof, there shall be no redetermination of tract participations but such working interest owner shall reimburse all other working interest owners for the share of (i) pre - unitization costs payable pursuant to Section 3 hereof, and (ii) costs incurred in development of the unit and plant from and after the Effective Date under this agreement and the unit operating agreement, that it would have incurred in each case, had it held such working interest at all times . Within thirty ( 30 } days after the joinder, the Unit Operator shall issue to each working interest owner a schedule showing such Party's actual share of such expenditures incurred prior to the joinder, the share that such Party would have borne had the new working interest owner always held such working interest, and the amount owing by such new working interest owner to each other working interest owner . The new working interest owner shall pay the amounts owing to the Unit Operator, and upon receipt of such amounts the Unit Operator shall promptly pay the amounts owed to the other working interest owners in accordance with the amounts owing to each . The new working interest owner shall pay the amount owing in full at the end of the calendar month following the calendar month in which the Unit Operator delivers its schedule under this paragraph . Should the new working interest owner fail to pay such amount when due, no other Party shall be obligated to contribute the amounts in default, but all other rights and remedies referenced in Section 7 shall apply with respect to such default . In the event that previously unleased rights to unitized substances that have been committed to the unit are leased but the working interest owner fails to join this agreement and the unit operating agreement in conformance with the requirements hereof and thereof within sixty ( 60 } days of such leasing, such failure shall be treated in the same manner as a loss of title to a working interest under Section 27 . 29. COUNTERPARTS . This agreement may be executed in any number of counterparts, no one of which needs to be executed by all Parties, or may be ratified or consented to by separate instrument in writing specifically referring hereto and, subject to approval hereof by the State AO and the Federal AO, shall be binding upon all those Parties who have executed such a counterpart, ratification, or consent hereto with the same force and effect as if all such Parties had signed the same document and regardless of whether or not it is executed by all other Parties owning or claiming an interest in the lands within the above - described unit area . 30. SURRENDER . Nothing in this agreement shall prohibit the exercise by any working interest owner of the right to surrender vested in such Party by any lease, sublease, or operating agreement as to all or any part of the lands covered thereby, provided that any person who will or might acquire such working interest by such surrender or by forfeiture as hereafter set forth, is bound by the terms of this agreement . If, as a result of any such surrender, the working interest rights as to such lands become vested in any person other than the fee owner of the unitized substances, said person may forfeit such rights and further benefits from operation hereunder as to said land to the person next in the chain of title who shall be and become the owner of such working interest . If, as a result of any such surrender or forfeiture, working interest rights become vested in the fee owner of the unitized substances, such owner may for a period of six ( 6 ) months after such surrender or forfeiture : (a) Accept those working interest rights subject to this agreement and the unit operating agreement; or (b) Lease the portion of such land as is included in a Participating Area established hereunder subject to this agreement and the unit operating agreement and cause its Jessee to join this agreement and the unit operating agreement ; or (c) Exclude any part of such land from the unit area that is not then included within a Participating Area established hereunder; or (d} Accept that the benefits and obligations of operations accruing to such lands under this agreement and the unit operating agreement shall be shared by the remaining owners of unitized working interests in accordance with their respective working interest ownerships, and such owners of working interests shall 19 DBI/63287028

compensate the fee owner of unitized substances in such lands by paying sums equal to the rentals, minimum royalties, and royalties applicable to such lands under the lease in effect when the lands were unitized. In the event such fee owner makes no election with such six (6) month period, it shall be deemed to have elected option (d). An appropriate accounting and settlement shall be made for all benefits accruing to or payments and expenditures made or incurred on behalf of such surrendered or forfeited working interest subsequent to the date of surrender or forfeiture, and payment of any monies found to be owing by such an accounting shall be made as between the affected persons within thirty ( 30 ) days . The exercise of any right vested in a working interest owner to reassign such working interest to the person from whom obtained shall be subject to the same conditions as set forth in this section in regard to the exercise of a right to surrender . 31.

The working interest owners for each tract shall render and pay for their account and the account of their royalty owners all valid taxes on or measured by the unitized substances in and under or that may be produced, gathered and sold from the land covered by this agreement and allocated to such working interest owner's tract after the Effective Date, or upon the proceeds derived therefrom . excluding taxes measured by income, profits or capital gains and excepting cases where the applicable leases provide that the royalty owners are responsible for handling payment of such taxes . The working interest owners on each tract shall and may charge the proper proportion of said taxes to royalty owners having interests in said tract, and may currently retain and deduct a sufficient amount of the unitized substances or derivative products, or net proceeds thereof, from the allocated share of each royalty owner to secure reimbursement for the taxes so paid .
