                                      -----

          This agreement made and entered into this 1st day of May, 1977, by and
between the State of Nevada, Department of Human Resources, hereinafter called
"LESSOR," and Nuclear Engineering Company, Inc., hereinafter called "LESSEE," a
corporation duly organized and existing under the laws of the State of
California, authorized to do business in the State of Nevada, having its
registered office in Beatty, Nevada, and authorized to engage in the business of
receiving, possessing, processing, repackaging, using, storing and disposing of
radioactive wastes and materials by License No. 04-3766-01 issued by the Nevada
State Health Division, and being further authorized by appropriate perm issued
in accordance with applicable provisions of law to engage in the disposal of
chemical and toxic wastes and materials.

                                   WITNESSETH:
                                   ----------

          WHEREAS, LESSOR has determined that a facility for the disposal of
low-level radioactive waste materials may be maintained in the State of Nevada;
and

          WHEREAS, LESSOR has determined that a facility for the disposal of
chemical and toxic waste and materials may be maintained in the State of Nevada;
and

          WHEREAS, LESSOR has procured certain real estate hereinafter referred
to as the "Site";

          NOW, THEREFORE, in consideration of the payments reserve herein and
the mutual covenants made by the parties, it is agreed as follows:

          I.  RENTAL-LICENSE FEE.  For and in consideration of the terms,
          ----------------------
covenants, payments, conditions and restrictions hereinafter set forth, the
LESSOR, pursuant to Chapter 374 of the 1961 Statutes of Nevada, does hereby
lease, let and demise unto LESSEE the following described premises situate in
the County of Nye, State of Nevada, more particularly described as follows, to
wit:

               All that certain piece, parcel or

               tract of land located in the NW1/4

               NE1/4; NE1/4 NW1/4 of Section 35,

               Twp. 13 South, Range 47 Ease, M.D.B.&M.

               containing 80 acres, more or less.


                                        1
<PAGE>
          To have and to hold unto the LESSEE for the term of twenty (20) years
from the effective date hereof, with the option to extend for an additional in
accordance with the terms of this lease, at a yearly rental of ten thousand
($10,000.00) per year, the first annual payment acknowledged, and succeeding
payments to be payable annually within twenty (20) days after the anniversary
date of this lease.  The rental payments shall be payable to the LESSOR;
provided, however, that in the event regulations are promulgated establishing a
license fee for the issuance of a license to dispose of low-level radioactive
waste it is acknowledged and agreed that LESSEE shall have as a full credit
against the payment of the aforestated license fee any and all rental fees
previously paid under this lease.  Further, LESSOR and LESSEE agree that upon
the establishment of a license fee that LESSEE'S responsibility for payment of
any and all rental fees, as set forth in this lease, shall immediately cease and
the rental fee terms contained herein shall be null and void at that time.

          II.  RENEWAL OF LEASE.  The term of this lease shall be extended for
          ---------------------
an additional ten (10) year term if, prior to six (6) months before the end of
the term but not before nineteen (19) years from the effective date of this
lease, the LESSEE makes written request to the LESSOR that it wishes to exercise
its option to extend under this paragraph.  The LESSOR may, notwithstanding
LESSEE'S option herein, declare the lease terminated at the end of the initial
term if, after consultation with the State Health Officer, it makes a reasonable
determination that, considering the volume of waste materials buried at the Site
and the available space remaining, that an extension for an additional term
would not be feasible.  The LESSOR may, however, extend the lease for a term
less than ten (10) years if, after consultation with the State Health Officer,
it determines that such an extension is feasible, considering the factors
hereinbefore set forth.  The LESSOR'S determination of feasibility under this
paragraph is subject to review by the State Board of Health.

          III.  OPPORTUNITY FOR HEARING.  Prior to the issuing of any order or
          -----------------------------
the making of any determination including but not limited to the denial,
modification or revocation of this lease the LESSOR and the State Board of
Health shall give reasonable notice in writing by certified mail to the LESSEE
and shall afford the LESSEE an opportunity for a hearing within twenty (20)
calendar days after giving the aforesaid notice.

          IV.  ASSIGNMENT.  The LESSEE may not assign the lease, nor any right
          ---------------
inuring to its benefit by virtue of any term or covenant herein set forth,
without prior written approval of the LESSOR.  For purposes of this paragraph a
sale or change of Corporate ownership directly affecting this lease shall be
deemed


                                        2
<PAGE>
an assignment requiring prior written approval by LESSOR as to the technical
competence of the assignee to assume burial operations, it being understood and
agreed that technical competence shall, as a minimum, be deemed legal and
factual capability for successfully obtaining and carrying out lawful activity
under either a license issued in accordance with law for the receipt, storage
and disposal of chemical and toxic waste materials. The parties acknowledge and
agree that the LESSOR shall not unreasonably withhold its approval of any
proposed assignment by LESSEE.

          The LESSEE agrees that it will not, without the written consent of the
LESSOR, sublet the premises or any part thereof or permit the use of the
premises by any party other than the LESSEE.

          V.  TERMINATION.  The LESSOR and LESSEE agree that the primary purpose
          ---------------
for which this lease is entered into is the proper burial and disposal of
radioactive and chemical and toxic wastes and materials and any other activity
which may lawfully be carried out under the terms of License No. 04-3766-01 or
any other provision of Nevada Revised Statutes.  The parties, therefore,
expressly agree that the portion of the lease providing for the disposal or
burial of radioactive waste may, at the option of the LESSOR, terminate after
hearing and opportunity for judicial review is afforded LESSEE in the event
License No. 04-3766-01 and all amendments thereto or any renewal thereof expires
without timely application for renewal thereof having been made or for any
reason ceases to be effective.

          VI.  RENEWAL OF LICENSE.  The LESSEE shall diligently and
          -----------------------
expeditiously provide the State Health Officer with information as required by
law for processing any application LESSEE may submit for any renewal of its
license issued under NRS Chapter 459.  Failure on the part of the LESSEE to
timely file an application for renewal in accordance with applicable State
regulations, after notice to the LESSEE and reasonable opportunity to file
following such notice, not to exceed thirty (30) days, may be deemed an
expression of intent on the part of the LESSEE to voluntarily surrender the
portion of the premises utilized for the disposal of low-level radioactive waste
unto the LESSOR who may then declare that part of the lease terminated by
serving written notice of its intent to terminate under this paragraph upon
LESSEE.  In no event, however, shall such an aforesaid voluntary surrender or
termination of the LESSEE'S rights to dispose or bury low-level radioactive
waste affect the portion of the lease that provides for the disposal of chemical
and toxic wastes and materials and in that respect this lease shall continue in
full force and effect.


                                        3
<PAGE>
          VII.  LIMITED TERMINATION-ADJUSTMENT OF BURIAL FEE.  The LESSOR and
          --------------------------------------------------
LESSEE further agree that a termination or voluntary surrender of one of
LESSEE'S rights to dispose of or store either low-level radioactive wastes or
chemical and toxic wastes and materials shall not affect LESSEE'S right under
this lease to continue to dispose of or store any of the other aforestated
materials not so terminated or surrendered.  LESSEE agrees that in the event it
continues operations at either Site not so terminated or surrendered LESSEE will
renegotiate a reasonable adjustment, if any, in the burial fee applicable to the
Site retained by LESSEE.

          VIII.  COMPLIANCE WITH APPLICABLE LAWS.  The LESSEE covenants and
          --------------------------------------
agrees that it will use the leased premises only for the purposes for which this
lease is entered into and in all respects in accordance with the laws of the
State of Nevada, and with the requirements specified in License No. 04-3766-01
and all amendments thereto or renewal thereof.  It is expressly understood that
the LESSEE shall comply with all applicable laws, rules and regulations of the
United States, and all applicable regulations of the State of Nevada as the same
are properly promulgated and amended from time to time by the Nevada State Board
of Health and the Nevada State Environmental Commission.  However, if the LESSEE
is required to comply with any Federal or State laws, rules or regulations that
render it prohibitive economically or otherwise, for LESSEE to continue its
rights and obligations under this lease the parties agree to immediately
renegotiate those provisions of this lease affected by such laws, rules or
regulations.

          If, within ninety (90) days after LESSEE'S written request to
renegotiate the lease, the parties fail to reach agreement, either party shall
thereafter have the right to cancel this lease, within thirty (30) days.

          IX.  INSURANCE.  The LESSEE shall provide adequate hazard and fire
          --------------
insurance at its own proper expense on all outbuildings, fixtures and other
personal property situate on the leased premises, with loss payable provisions
in favor of the LESSEE.  The proceeds from any hazard or fire insurance shall be
used by the LESSEE to replace all or so much of said outbuildings, fixtures or
other personal property as may be economically reasonable and feasible.

          X.  REPAIRS.  The LESSEE shall make all necessary repairs or
          -----------
improvements as may be economically reasonable or feasible to all outbuildings,
fixtures and other personal property situate on the leased premises at its own
proper expense.


                                        4
<PAGE>
          XI.  FEES FOR PERPETUAL CARE AND MAINTENANCE.  The LESSEE agrees to
          --------------------------------------------
pay LESSOR the sum of thirteen cents (13 ) for each and every cubic foot of
low-level radioactive waste materials and seven cents (7 ) for each and every
cubic foot of chemical and toxic waste materials which is disposed of or buried
upon the described premises to provide funds for a perpetual care and
maintenance trust fund as provided by law.

          The amounts payable to LESSOR for the disposal or burial of low-level
radioactive waste or chemical and toxic waste under this lease are for a term of
ten (10) years from the effective date of this lease.  At the expiration of each
ten (10) year period the LESSOR and the LESSEE hereby agree to conduct a joint
technical study to reevaluate the then existing conditions.  Subsequent to the
completion of the aforestated joint study should additional funds be determined
necessary then the parties agree to renegotiate the cubic foot amounts payable
to LESSOR; provided, however, LESSOR agrees that any increase in the amounts to
be paid for each and every cubic foot of low-level radioactive waste or chemical
and toxic waste disposed of or buried upon the premises shall not exceed one
hundred percent (100%) of the then current rates.

          XII.  PREPAYMENT.  LESSEE shall pay to LESSOR the sum of FIFTY
          ----------------
THOUSAND AND NO/100 DOLLARS ($50,000.00) which shall constitute a prepayment for
the disposal and/or burial of radioactive, chemical and toxic wastes and
materials on the heretofore described premises.   All prepayments shall be
deposited by LESSOR in the radioactive materials disposal fund as provided by
law.  The aforesaid prepayment shall be debited by LESSOR in accordance with the
existing perpetual care and maintenance contribution rates and the monthly
burial or disposal quantities for radioactive, chemical and toxic waste and
materials.  LESSEE shall provide additional prepayments when the balance of the
deposit is equal to five percent (5%) of the original prepayment,
notwithstanding that such prepayments may occur at intervals more frequent than
on a yearly basis.  Furthermore, LESSOR and LESSEE agree that LESSEE shall
receive full credit and appropriate adjustments for any and all prepayments made
prior to the execution of this lease document.  In the even this lease is
terminated for whatsoever reason, LESSOR agrees that LESSEE shall receive a full
refund for any and all prepayment amounts not previously debited by LESSOR in
accordance with all applicable provisions of this lease.

          The LESSOR and LESSEE acknowledge and agree that the primary purpose
of LESSEE'S payment to LESSOR of the cubic foot charge on low-level radioactive,
chemical and toxic wastes disposed of


                                        5
<PAGE>
or buried at the Site is to provide funds for satisfactory surveillance in
conjunction with the implementation of proper safeguards for the public health
and safety upon expiration of the lease term or extension thereof and final
closure.

          XIII.  MINIMUM BURIAL DEDUCTION.  It is understood that the primary
          -------------------------------
purpose for the assessment of the aforestated burial rate is to ensure the
adequate growth of a perpetual care and maintenance fund.

          In order to stimulate the growth of the perpetual care and maintenance
fund, LESSOR shall deduct for any six (6) month operating period the minimum
amount of TWELVE THOUSAND AND NO/100 DOLLARS ($12,000.00) from the burial
prepayment as set forth in Section XII herein.  The Minimum Burial Deduction
amount will be adjusted at the end of each five (5) year calendar period during
the term of this lease or any extension thereof.  The adjusted minimum deduction
amount will be computed by multiplying the annual average of the latest five (5)
years' deposits by the then current contribution rates and said adjustment will
be effective for the next succeeding five (5) year period.

          The LESSOR agrees to make adjustments on a consecutive twelve month
basis in the event actual revenue earned by the LESSOR falls below the minimum
burial deduction; LESSEE shall receive a credit to the prepayment in the amount
of the difference between the minimum burial deduction and the actual revenue
earned.  However, if the actual revenue earned by the LESSOR from collection of
the burial rates set forth in Section XI exceeds the applicable minimum
deduction set forth in the preceding paragraph, the actual revenue earned will
be deducted from the prepayment set forth in Section XII.

          LESSOR and LESSEE agree that LESSEE'S performance as set forth in this
provision shall be excused for any month in the event of an act of God, war,
riot; fire, lack of adequate fuel; power, labor, transportation; compliance with
governmental requests, actions, laws, regulations, orders or action, or in the
event of labor trouble, (provided that LESSEE shall not be required to settle a
labor dispute against its own best judgment); or any other event beyond the
reasonable control of LESSEE; which event prevents the delivery, transportation,
acceptance or disposal of waste products.

          XIV.  VIOLATIONS.  The LESSEE will not, without the LESSOR'S consent
          ----------------
violate any of the terms and conditions of this lease, or the terms of
authorizing licenses issued by the State of Nevada.  If such violations, misuse,
or noncompliance occur, which result in lawful revocation of License No.
04-3766-01


                                        6
<PAGE>
or any amendment thereto or renewal thereof, the LESSOR shall have the right,
upon written notice of its intention and after providing an opportunity to
LESSEE for hearing as provided herein and judicial review, to terminate this
lease solely as to that portion thereof providing for radioactive waste
disposal.

          XV.  COMPENSATION TO LESSEE UPON TERMINATION.  In the event of such
          --------------------------------------------
termination of this lease as to that portion providing for radioactive waste
disposal should LESSOR relet that portion of the Site to any other party for the
same, similar, or allied use, LESSEE shall be entitled to reasonable
compensation, including, but not limited to, any and all buildings and other
Site improvements left thereon.  In the event LESSOR or LESSEE cannot reach an
agreement as to the amount of such compensation, the same shall be submitted to
arbitration before an arbitrator appointed by the American Arbitration
Association.  The costs of said arbitration shall be borne equally by the
parties.

          XVI.  WAIVER.  The LESSEE agrees that the LESSOR'S failure to insist
          ------------
upon the strict performance of any provision of this lease, failure to exercise
any right based upon a breach thereof, or the acceptance by the LESSOR of any
fees during such breach shall not waive any of the LESSOR'S rights under this
lease except when the LESSOR has agreed in writing to waive such rights.

          XVII.  INDEMNITY.  LESSEE agrees to indemnify and save LESSOR harmless
          ----------------
from and against any and all claims, demands, suits, damages, expenses and
liabilities brought by a third party to the extent that any injury to or death
of any person or any damage to or loss of property arises out of the sole
negligence of the LESSEE.

          XVIII.  CLOSURE REQUIREMENTS.  Upon final legal termination, legal
          ----------------------------
termination prior to expiration of the term of this lease, or formal voluntary
surrender of LESSEE'S rights to store or dispose of low-level radioactive waste
material, LESSOR and LESSEE acknowledge and agree that LESSEE shall perform the

          XXI.  SOVEREIGN AUTHORITY.  It is understood that none of the terms of
          -------------------------
this lease, nor any of the covenants herein contained, shall operate to restrain
the LESSOR from fulfilling its responsibilities in its capacity as sovereign of
the State of Nevada, including, but not limited to, a determination on the part
of the sovereign that a public emergency exists and that immediate State action
be formally determined as necessary.  Should the aforestated State action be
formally determined as necessary, LESSOR shall, as provided in NRS 459.130 or
any amendment thereto, upon LESSEE'S application, promptly afford LESSEE an
opportunity to be heard and to present proof that such a condition or activity
does not warrant the original determination.

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

          This Addendum Agreement made and entered into this the seventh day of
December, 1979, by and between the State of Nevada, Department of Human
Resources, hereinafter called "LESSOR," and Nuclear Engineering Company, Inc.,
hereinafter called "LESSEE," a corporation duly organized and existing under the
laws of the State of California, authorized to do business in the State of
Nevada, having its registered office in Beatty, Nevada, and authorized to engage
in the business of receiving, possessing, processing, repackaging, using,
storing and disposing of radioactive wastes and materials by License No.

                                   WITNESSETH:
                                   ----------

          WHEREAS, LESSOR and LESSEE entered into a Lease dated May 1, 1977,
whereby LESSOR leased to LESSEE certain real property in Nye County, Nevada,
hereinafter known as the "Site";

          WHEREAS, LESSOR and LESSEE have determined that additional monetary
consideration in the form of increased yearly rental payments Need to be
provided in order that LESSOR may further ensure that it has sufficient
personnel to continue and administer its on-site surveillance of that portion of
the Site pertaining solely to low-level radioactive waste; and

          WHEREAS, LESSOR and LESSEE have mutually agreed to raise the per cubic
foot Perpetual Care and Maintenance payments for low-level radioactive waste
paid by LESSEE in order to further accelerate the growth of the Perpetual Care
and Maintenance Trust Fund maintained by the LESSOR;
