Manuel Cadena Survey 242, A-1240, the Manuel Cadena Survey 149, A-977, the
Hippolito Garecia Survey 115, A-998 and the Hippolito Garcia Survey 95, A-881
all out of Duval County, Texas.

In the event above-described lands are not described correctly, Lessor agrees to
execute an instrument or instruments in which to correctly describe the property
or properties.

     1. Said property is leased for the purposes of investigating, exploring,
prospecting, drilling, solution mining, producing, extracting, milling,
treating, processing, upgrading, removing, transporting, stockpiling and storing
uranium, thorium and other fissionable or spatially associated substances
similar to and produced in conjunction with those mentioned above (hereinafter
referred to individually or collectively as "Leased Substances") by methods
deemed desirable by Lessee; but excluding sand, gravel, and caliche unless
produced in connection with those mentioned; SPECIFICALLY EXCLUDING oil, gas and
associated hydrocarbon substances. Lessor further grants, leases and lets unto
Lessee the Leased Land for the purposes of injecting gas, water or other fluids
commonly associated with solution mining practices, air and any other substance
into the subsurface strata, conducting all types of solution mining recovery
operations for the Leased Substances; establishing and using facilities for the
disposition of solution, tailings and other waste materials produced in the
extraction of the Leased Substances, laying pipeline, building roads, bridges,
tanks, power and telephone lines, electric and distribution lines and other
utilities together with the maintenance and removal thereof, mills or processing
structures or facilities deemed reasonably necessary by Lessee to conduct
solution mining, recovery and restoration operations granted under this lease.

Notwithstanding, however, the general provisions of the foregoing paragraph, it
is further agreed and stipulated as follows:

     The facilities to be placed on the Leased Premises shall be confined to
those facilities reasonably deemed necessary or convenient by Lessee for
exploring, prospecting, mining, stockpiling, storing, processing, treating
upgrading, removing and transporting the Leased Substances. Lessee is hereby
granted the right, without any further consideration or payment, to use the
Leased Premises and other improvements and facilities on, in or under the Leased
Premises for or in connection with the mining, removing, transporting,
preparation and treatment of minerals, metals and materials (and disposal of
waste materials into a waste water disposal well at a site at Lessee's choice)
from adjacent lands, and lands in the areas of interest, and to construct and
use additional facilities on the Leased Premises for said purposes. and these
rights shall survive termination of this lease for so long a period of time as
Lessee has need for all or any of them.

     2. Subject to the provisions herein contained, this lease shall remain in
force for a term of eight (8) years from the date first written above
(hereinafter referred to as the "Primary Term") and so long thereafter as
uranium or any of the other Leased Substances is produced in paying quantities
from said Leased Land or land with which said Leased Land is pooled, and/or as
long thereafter as this lease may be maintained in force and effect under any of
the other provisions herein contained. Paying quantities being defined as
production in quantities sufficient to yield a profitable return to Lessee in
excess of drilling, development and operation costs set solely at the discretion
of the Lessee.

--------------------------------------------------------------------------------

     3. Royalties: Lessee agrees to pay Lessor royalty on Leased Substances
produced, saved and sold from the Premises as follows:

  a

If Leased Substances mined and produced from the Premises by Lessee are sold by
Lessee on the basis of a price per pound, Lessee shall pay to Lessor a
production royalty on such Leased Substances equal to the percentage determined
in the manner set forth below of the amount paid to and received by Lessee upon
the sale of such Leased Substances through an arms-length transaction. An
"arms-length transaction" as used in this Paragraph 3, shall be deemed to be a
bona fide transaction with a third party purchaser not an affiliate, subsidiary
or parent of Lessee, or other entity in which Lessee has a financial interest by
stock ownership or otherwise of 10% or more. If such Leased Substances are used
by Lessee off the Premises, or sold other than through an arms-length
transaction, then the appropriate royalty percentage shall be applied to the
market value of such Leased Substances after the same has been processed and
assayed. If there is no such market value on or near the Premises as of the date
such Leased Substances are used or sold, such market value shall be determined
in the general area in which the Premises are situated, or if there is no such
market in the general area, then at the closest market to the Premises. The
royalty percentage contemplated by this Paragraph 3A shall be determined as
follows:

  Price per Pound for which Royalty   Leased Substances are Sold Percentage Rate
  Less than $30.00 6.00%   $30.01 or more but less than $35.00 7.00%   $35.01 or
more 8.00%

  b

All royalty payments provided for herein shall be paid either directly to Lessor
or to the depository bank(s) named hereinabove, and shall be payable not later
than the 25th day of the month following the month in which Lessee receives
payment therefor.

        c

Lessor shall have the right, upon 90 days notice to Lessee, to receive Lessor's
royalty in kind, provided that any such election by Lessee must be for a minimum
term of at least one (1) year, and Lessor, at Lessor's sole expense, shall make
available to Lessee all necessary facilities to enable Lessee to deliver
Lessor's royalty share of Leased Substances to Lessor.

        d.

Notwithstanding the use of the term Leased Substances in this Paragraph 3, if
any other valuable metals, minerals and ores, whether similar or dissimilar to
uranium, thorium, vanadium, molybdenum, and all other fissionable materials,
compounds, solutions, mixtures and source materials, or any one of them and
which are necessarily produced in association therewith are produced and
marketed from the Leased Premises, Lessor shall be paid a production royalty of
10% of the gross sales price of such valuable metals, minerals and ores.

The above listed Royalty percentages will be paid based on the actual net sales
proceeds received by Lessee for yellowcake, or slurry, sold and delivered
through an arms length transaction. An arms length transaction shall be deemed
to be a bona fide transaction with a third party purchaser, not an affiliate,
subsidiary or parent of Lessee, or other entity in which Lessee has a financial
interest by stock ownership or otherwise of Ten Percent (10%) or more.

All royalties which are due and payable under the terms of this lease, shall be
paid within twenty-five (25) days after the end of the calendar month within
which Lessee receives the proceeds from the sale of the uranium or other Leased
Substances, which payment shall be subject to adjustment, by addition to or
deduction from royalty due, as a result of actual sale assay. Lessee's failure
to pay or tender or timely pay or tender any sum as royalty, shall render Lessee
liable for the amount due plus simple interest of Twelve Percent (12%), but
shall not operate as a forfeiture or to terminate this lease.

     4. Lessee shall use reasonable diligence to sell the uranium or Leased
Substances and any of them, on which royalty is payable under the terms of this
lease, but in the exercise of such diligence Lessee shall not be obligated to
sell the same, or any of them, under terms, conditions or circumstances which in
the Lessee's judgment, exercised in good faith, is not in its best interest.

     5. If Lessee, through the drilling of a well or wells has discovered
uranium or other Leased Substances on said Leased Land or on land pooled
therewith, which in Lessees' opinion is capable of being produced in commercial
quantities, but is not being produced and this lease is not being maintained
otherwise as provided herein; or if Lessee after commencement of production,
periodically suspends production or sales and stockpiles uranium or other Leased
Substances for lack of a market reasonably satisfactory to Lessee, as determined
by Lessee in its sole discretion, then this lease shall not terminate whether it
be during the Primary or Renewal Term (unless released by Lessee), and it shall
nevertheless be considered that uranium or other Leased Substance is being
produced in paying quantities from said Leased Land provided a Shut-in Royalty
is paid. When the lease is continued in force in this manner, Lessee shall pay
or tender as a Shut-in Royalty to the parties who at the time of such payment
would be entitled to receive Royalty hereunder if production were then
occurring, a sum of Ten Dollars ($10.00) per acre on the number of acres subject
to this lease at the time such payment is made for each lease year, or portion
thereof, that this lease is not otherwise maintained. When the above Shut-in
payment is made, it shall serve to extend the term of said lease for one (1)
year from the date said payment is made, whether in the Primary or Renewal Term.
The first payment of such sum shall be made on or before the first day of the
calendar month after ninety (90) days from the date the lease is not otherwise
maintained and thereafter annually on or before each succeeding anniversary date
of such payment. Payments made as Shut-in Royalty under this paragraph shall be
made as advance minimum royalty and after royalty begins to accrue hereunder,
Lessee may offset royalty owing to Lessor by deducting the abovementioned
advance minimum royalty. Advance minimum royalty shall constitute prepayment of,
and advances against royalty accruing at any time hereunder and Lessee may
recover all advance minimum royalty by crediting it against and in reduction of
royalty becoming due at any time until all advance minimum royalty has been
recovered by Lessee.

--------------------------------------------------------------------------------

     6. If mining operations are not commenced on said Leased Land or on land
pooled therewith on or before one (1) year from the date first above stated,
this lease shall terminate unless on or before such date Lessee shall pay or
tender, or make a bona fide attempt to pay or tender to Lessor or to the credit
of Lessor or Lessor's in _____________________________________ Bank the sum of
Ten Dollars ($10.00) per acre multiplied by the number of acres retained under
this lease (hereinafter referred to as "Rental"), which shall cover the
privilege of deferring commencement of mining operations for a period of twelve
(12) months. In like manner and upon like payment or tender annually, the
commencement of mining operations may be further deferred for successive period
of twelve (12) months each during the Primary, Renewal and Continuing Term. The
payment or tender of Rental under this paragraph or of any other payment coming
due under the terms of this lease may be made by check or draft of Lessee mailed
to the parties entitled thereto or to said Bank on or before the due date of
such payment Such Bank or its successor, is hereby designated as Lessor's agent
to receive from Lessee all payments by Lessee to Lessor under the terms of this
lease and shall continue as depository for all payments hereunder regardless of
changes of ownership of the Leased Land and/or Leased Substances. Lessees'
obligations to Lessor as to the payment of money under the terms of this lease
shall end upon payment of the correct amounts to Lessor or said Bank, as set
forth in this paragraph, and Lessee in no manner shall be responsible for any
disposition or distribution of moneys so paid or deposited. In the event that
such bank (or any successor bank) should fail, liquidate or be succeeded by
another bank, or for any reason fail or refuse to accept payment, or should
Lessor or any Assignee or Assignees desire to designate another depository bank,
then Lessee shall not be held in default for failure to make payment or tender
payment until thirty (30) days after Lessor, or Lessor's Assignees, shall
deliver to Lessee a proper recordable instrument, naming another bank as agent
to receive such payments or tender.

     7. If at any time Lessee is in default in the performance of the terms and
conditions of this lease to be performed by it, and if, within sixty (60) days
after written notice of the default is given by Lessor to Lessee, Lessee has not
commenced activities which will cure the default if pursued diligently, then
Lessor may terminate this lease by written notice to Lessee. If the default is
due to failure to timely pay, ineffective or erroneous payment or deposit as
described herein, this lease shall not terminate, but shall be maintained in the
same manner as if such failure to timely pay, ineffective or erroneous payment
or deposit had been properly made, provided that the abovementioned payment,
Rental or Royalty payment be corrected within sixty (60) days after the receipt
by Lessee of written notice by such party or parties of such error, accompanied
by such instruments as are necessary to enable Lessee to make proper payment.

     8. If at the expiration of the Primary or Renewal Term uranium or other
Leased Substances is not being produced from said Leased Land or land pooled
therewith, but Lessee is engaged in operations directed toward the establishment
or re-establishment of production therefrom, this lease shall remain in force so
long as such operations are prosecuted with no cessation of more than ninety
(90) consecutive days; and if the operations result in production, so long
thereafter as uranium or other Leased Substances is produced from said Leased
Land or land pooled therewith. If production of uranium or other Leased
Substances from said Leased Land or land pooled therewith has been obtained, and
such production shall cease for any cause, whether on one or more occasion, this
lease shall not terminate if Lessee commences or resumes operations directed
towards the re-establishment of production from said Leased Land or land pooled
therewith within ninety (90) days after cessation of production and such
operations continue with no cessation of more than ninety (90) days until
production is re-established, or if it be within the Primary or Renewal Term,
commences or resumes the payment or tender of Rentals or commences operations
directed towards to re-establishment of production on or before the Rental
payment date next ensuing.

     9. If, upon the expiration of the Primary Term, no mining, development or
processing is being conducted, and regardless of whether the Primary Term of
this lease is extended by some other provision herein, then Lessee shall have
the right to extend this lease for an extended primary term by the payment to
Lessor of an extension bonus in the amount of Seventy-five Dollars ($75.00) per
acre multiplied by the number of acres then covered by this lease, and upon
payment or tender, this lease shall automatically and without further action on
the part of Lessor or Lessee and without execution of any additional instrument,
be renewed for a term of five (5) years from and after the Primary Term hereof
(hereinafter referred to as the "Renewal Term") and so long thereafter as
uranium or other Leased Substances is being produced in paying quantities from
said Leased Land or land with which said Leased Land is pooled. On or before
each anniversary date thereafter, Lessee shall pay to Lessor a delay rental in
the amount of Five Dollars Fifteen Dollars acre multiplied by the number of
acres retained under this lease which delay rentals shall not be recoupable
against any royalty becoming due at any time to Lessor.

--------------------------------------------------------------------------------

     This lease is also granted for a continuing term as long after the Primary
or Renewal Term as any inning, development or processing is being conducted
hereunder on a continuous basis. Such operations shall be deemed conducted on a
continuous basis unless and until, after the end of the Primary or Renewal Term,
a period of one hundred eighty (180) consecutive days elapses in which no such
operations are conducted, excluding, however, periods of force majeure as
provided herein.

     10. Lessee is hereby granted the right to pool all or any part of said
Leased Land with any other land, lease or leases in the vicinity thereof when in
Lessee's judgment it is necessary or advisable to do so for the purpose of
exploring or developing and operating the Leased Premises for in situ leach or
solution mining operations whether owned by Lessor or a third party at any time
and from time to time to explore, drill, solution mine, operate for, produce,
extract, remove and transport uranium or other Leased Substances, provided the
area so pooled shall, as near as practicable, cover only the delineated ore body
from which production attributable to the pooled area is concerned, but in no
event shall the pooled area exceed twenty (20) acres in size. For the purpose of
determining Royalty hereunder, any uranium or other Leased Substances produced
from the land so pooled shall be allocated to said Leased Land on the basis the
surface acreage contributed by said Leased Land relates to the total surface
acreage of the land so pooled. It shall be conclusively presumed that the
uranium or other Leased Substances produced from such pooled land is produced
uniformly within the boundaries of the pooled land both as to quantity and
quality, and the amount allocated to the Leased Land shall, for all purposes
hereunder, be presumed to have been produced from said Leased Land.

     11. Lessee shall have the right from time to time and at any time to mix or
commingle uranium or other Leased Substances from the Leased Land or land pooled
therewith with like substances produced from other land for transporting,
treating, processing and storing prior to or for the purpose of sale. Prior to
such mixing or commingling the uranium content or other Leased Substances
content where such are being processed for sale, of the raw ore or the amount
thereof in solution (as the case may be), shall be assayed or otherwise
determined by periodic sampling, using sound engineering principles and the
volume of all solutions produced shall be determined by adequate metering
devises. For Royalty purposes, the uranium or other Leased Substances
attributable to the said Leased Land where such mixing or commingling has
occurred, shall be a percentage of the total uranium or other Leased Substances
sold by Lessee (including Lessor's share from pooled land in accordance with the
paragraph listed above), which percentage shall be determined by the
relationship of uranium or other Leased Substances content in the production
from said Leased Land, multiplied by the volume thereof (including Lessor's
share from pooled land) bears to the total uranium or other Leased Substances
content, multiplied by the total volume of the mixed or commingled production
from all land for the applicable production period.

     12 Lessee, its successors and assigns, shall execute and deliver to Lessor,
or to the depository Bank, or file for record, a release or releases of this
lease within ninety (90) days of the date of termination of that portion or
interval affected, in whole or in part of the Leased Land, Leased Substances,
subsurface interval or any depth thereunder, and Lessee shall thereby be
released from all obligations as to the released land, substances, horizon, zone
or formation as of the date of release. If this lease is released as to a
portion of said Leased Land, the Rental, Shut-in Royalty, or Royalty payments
shall thereupon be reduced in proportion that the acreage released bears to the
acreage which was covered by this lease immediately prior to such release.

     13. The rights of either party hereunder may be assigned in whole or in
part as to the Leased Land or any Leased Substances or subsurface interval or
any depth thereunder and the provisions hereof shall extend to the heirs,
executors, administrators, successors and assigns, but no change or division in
ownership of the Leased Land, Rental, Shut-in Royalty or Royalty, however
accomplished shall operate to enlarge the obligation or diminish the rights of
the Lessee or be binding upon Lessee for any purpose until sixty (60) days after
such person acquiring any interest has furnished Lessee with the instrument,
instruments or certified copies thereof, constituting his chain of title from
the original Lessor. In the event of an assignment of this lease as to a
segregated portion of said Leased Land, the Rental, Shut-in Royalty or Royalty
due hereunder shall be proportioned between the several leasehold owners ratable
according to the surface areas of each in the Leased Land, and default in
payment of one shall not affect the rights of the other leasehold owners
hereunder. An assignment by Lessee shall, to the extent of each assignment,
relieve and discharge Lessee of any obligation hereunder accruing after the date
of such assignment. If Lessee or assignee or part or parts hereof shall fail or
make default in payment of the proportionate part of the Rental, Shut-in Royalty
or Royalty payment due from such Lessee or assignee, or fail to comply with any
other provision of the lease, such default shall not affect the entire lease
insofar as it covers a part of said Leased Land upon which Lessee or any
assignee thereof shall make payment of said Rental, Shut-in Royalty or Royalty.
In the event of the death of any person entitled to any payment under the
provision of this lease, including Royalty, Lessee may pay or tender any such
payment to the credit of the deceased, or the estate of the deceased, until such
time as Lessee is furnished with proper evidence of the appointment and
qualification of an executor or administrator of the estate, or if there be
none, then until Lessee is furnished with evidence satisfactory to it as to the
heirs and devisees of the deceased and that all debts, taxes, state inheritance
taxes and federal estate taxes of the estate have been paid.

--------------------------------------------------------------------------------

     14. Lessee shall have free use of water (except water from Lessor's wells,
tanks and reservoirs) for all operations hereunder, however, Lessee shall have
the right to test water from these sources. Exploration, solution mining and
restoration operations wherever situated on the Leased Land shall be conducted
so not to damage or destroy any water supply constructed by Lessor. In the
event, however, that such activity, in order to properly explore, solution mine
and develop said Leased Land should result in damage to or in destruction of any
such water supply, if feasible in the opinion of Lessee, the Lessee, at his
option, shall repair, restore or replace any such well, tank, reservoir or other
water facility so damaged or destroyed, with reasonable diligence and dispatch,
weather permitting, or if not feasible then Lessee shall pay to Lessor a
reasonable compensation for any such damage so sustained. Any such water
facility so repaired, restored or replaced shall be of a capacity and quality
equal to that which was damaged or destroyed. Any claims for such damage or
destruction MUST be made within two (2) years following the termination of this
lease.

     15 Lessor, or his duly authorized representatives, shall have the right at
all reasonable times and at his own risk to enter into and upon said premises
and workings thereon for the purposes of examining and inspecting the same and
ascertaining whether the terms and conditions of this lease are being carried
out and performed by Lessee, so long as such access or inspection does not
interfere with the operations of Lessee; Lessor or his duly authorized
representatives, shall at all reasonable times have access to production
records, assays and evaluation of ore records, and all other records pertinent
and necessary for substantiating the compliance of Lessee with the provisions of
this lease. It is agreed and stipulated that neither the Lessee, its agents,
employees, contractors or subcontractors, their agents or employees, shall at
any time hunt or fish on the premises, nor shall they, or any of them, carry
onto the premises firearms or other equipment designed or adapted for such
purpose. Lessor, or his duly authorized representatives, shall have the right at
all times to inspect vehicles entering upon or leaving said premises for the
purpose of ascertaining whether the provisions of this paragraph are being
carried out

     16 Lessee agrees to conduct its mining operations on said Leased Land in a
workmanlike manner, abiding by all applicable State and Federal laws, rules and
regulations. In addition, Lessee agrees to make payment for surface usage
according to the following.

  a

To pay Lessor the sum of twenty-five dollars ($25.00) per exploration test hole
drilled by Lessee as FULL COMPENSATION for all damages to grass, crops and land
that occur during any exploration drilling operation.

        b.

Within sixty (60) days from the date any acreage is actually taken out of use by
Lessee, to pay to the Lessor owning the surface to that particular acreage taken
out of use, a one time sum of two hundred fifty dollars ($250.00) per acre.

        c

Insure all well holes will be filled, plugged, and covered with top soil as
required.

        d.

Once solution mining operations have ceased on said Leased Land and restoration
has been completed, with Lessee receiving FULL release from the governing
authority, Lessee shall return the surface configuration of the land so used to
as near the condition that existed immediately prior to Lessees operations
described herein and to deep plow the area disturbed, by methods common to the
area; if acreage is used for grazing purposes Lessee shall reseed the area so
plowed to prevent erosion with seed selected by Lessor that is consistent with
the surrounding area.

        e.

It is agreed and stipulated that no exploring or mining shall be conducted, nor
any facilities necessary to the same, constructed within one hundred fifty (150)
feet of the main dwelling place or appurtenant structures thereto, unless the
consent of Lessor, in writing, shall have been first obtained.

     All payments made under this lease for surface usage shall be based on the
actual acreage disturbed, rendered unharvestable or made unusable for pasture
and will be paid on a per acre basis, or portion thereof. If Lessor owns a
lesser interest in the surface of the lands covered by this lease less than the
entire fee simple estate, then any payment herein provided to be made to Lessor
which relates to the surface shall be proportionately reduced.

     17, Lessee shall endeavor to locate any road on the Leased Land at places
mutually agreeable to both Lessor and Lessee, consistent with Lessee's
operations. Lessor shall not make unreasonable objections to the location that
will cause undue restrictions or added costs to Lessee. All roads shall be
constructed and maintained in such a manner as to bear the traffic necessary to
Lessee's operations, and so as not to be a barrier to the natural drainage of
the site. Upon cessation of operations by Lessee and the termination of this
lease, all roads so constructed shall become the property of Lessor except,
however, that the Lessor reserves the option and privilege of requiring Lessee
to remove said road material from said Leased Land and to plow the surface below
ordinary plow depth by methods common to the area. Such option MUST be exercised
in writing by Lessor within thirty (30) days after the termination of this lease
Lessor shall have the right, at his own risk, to use any such road so
constructed by Lessee for Lessee's use so long as this use does not interfere
with the Lessee's use thereof.

--------------------------------------------------------------------------------

     18. If there are FENCES located on the premises and Lessee finds it
necessary to cut any fence or fences for the purpose of passage, Lessee agrees
that prior to cutting such fence there will be installed and braced heavy
"corner-type" posts at each end of the opening to be made, to which the fence
wire will be securely fastened in such a manner as to prevent sagging; Lessee
will install a gate of a quality acceptable to Lessor in each such opening; in
the event Lessee desires that such opening provide uninterrupted ingress and
egress, then Lessee shall install therein cattle guards of sufficient size and
substance to bear the type of traffic necessary for its operations and capable
of turning all domestic livestock; If there is livestock on said Leased Land,
Lessee agrees to properly fence all pits, fixed machinery and other hazards
which it may dig, bore or construct on the premises so as not to present a
hazard to such livestock; Lessee agrees to bury all pipelines, if requested by
Lessor, except those contained within a fenced area, enclosure or wellfield, so
that the top thereof is of sufficient depth so as not to interfere with the
surface operations of Lessor.

     19 Lessee shall have the right at any time during or within one (1) year
after the termination or expiration of this lease to remove all property and
fixtures placed by Lessee on said Leased Land. In the event the Primary and
Renewal Term of said lease have expired and complete restoration has not been
accomplished by Lessee, Lessee shall have the right of ingress and egress over
existing roads, to the acreage containing plant, well field, monitor wells and
other facilities associated with Lessee's operations, to complete the required
restoration of said Leased Land, without additional compensation, in accordance
with Federal and State regulations.

     20 In conducting its operations hereunder, Lessee shall fully comply with
the terms and provisions of the Workman's Compensation Laws of the State of
Texas, and shall hold the Lessor harmless against and from any and all loss,
damage or claims resulting in violations of workman compensation laws of
whatever nature or character occasioned by or arising out of its operation under
the terms and provisions of this lease, unless loss, damage or claims arises as
a result of act or of negligence of Lessor.

     21. Lessee shall not be liable for delays or defaults in its performance of
any agreement or covenant hereunder due to force majeure. The term "FORCE
MAJEURE" as employed herein shall mean. any act of God, including but not
limited to storms, floods, washouts, landslides and lightning; acts of the
public enemy; wars, blockades, insurrections or riots; strikes or lockouts;
epidemics or quarantine regulations, laws, acts, orders or requests of federal,
state, municipal or other governmental officers or agents acting under color of
authority; freight embargoes or failures; exhaustion, unavailability or delays
of any product, labor, service or material. If Lessee is prevented from
conducting or required to cease operations directed toward establishment or
re-establishment of production or producing operations by any order, decree,
direction, inaction or denial of permit by and federal, state or municipal law,
executive order, rule, regulation or request enacted or promulgated under color
of authority on said Leased Land or on land pooled therewith, or if Lessee by
other types of force majeure is prevented from conducting operations directed
toward establishment or re-establishment of production or producing operations,
then until such time as law, order, rule, regulations, request or other force
majeure is terminated or the permit issued and for a period of ninety (90) days
after such termination of issuance, each and every provision of this lease that
might operate to terminate it or the estate conveyed by it shall be suspended
and inoperative, and this lease shall continue in full force and effect. If any
period of suspension occurs during the Primary, Renewal or Continuing Term, the
time thereof shall be added to such term with continuing payment of annual
Rental, Shut-in Royalty or Royalty consistent with the applicable term for such
period of suspension

     22. Lessee shall have the right to terminate this lease at any time or
times during the term hereof, as to the subject minerals underlying all or any
one or more parts of the premises, by delivering or mailing to Lessor written
notice stating such intention to terminate and describing the parts of the
premises, if less than all, as to which the termination applies. The termination
shall take effect upon the date specified in the notice, or, if no date is
specified upon the date on which the date is given. Upon such termination, all
right, title, interest and obligations of Lessee hereunder in and to the
premises specified in the notice shall terminate, except obligations which then
have accrued under the express provisions of this lease and which they have not
