                    NON-DISTURBANCE AND ATTORNMENT AGREEMENT

     THIS AGREEMENT ("Agreement") is made and entered into as of the 10th day
of December, 1999 by and between E.THREE CUSTOM ENERGY SOLUTIONS, LLC, A NEVADA
LIMITED LIABILITY COMPANY, ("Tenant"), FITZGERALDS LAS VEGAS, INC., A NEVADA
CORPORATION (either "Landlord" or "Customer"), and FOOTHILL CAPITAL
CORPORATION, A CALIFORNIA CORPORATION ("Lender").

                                    RECITALS

     A.  Lender is the Beneficiary under that certain Deed of Trust, Security
Agreement and Fixture Filing with Assignment of Rents dated as of October 29,
1998 (as supplemented and otherwise amended from time to time) (hereinafter
"Mortgage") by and among Landlord, as Trustor, in favor of Lawyers Title
Insurance Corporation, as Trustee, for the benefit of Lender, as Beneficiary.
The Mortgage encumbers the Real Estate (hereinafter defined) and secures future
advances up to a principal indebtedness equal to $15,000,000.

     B.  Tenant will be entering into a lease agreement (such lease agreement,
together with all amendments and modifications thereof, is hereinafter referred
to as the "Lease") with Landlord, pursuant to which Tenant leased a certain
parcel of land in Las Vegas, Nevada (the "Real Estate") legally described in
Exhibit A attached hereto.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and for other valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties do hereby covenant
and agree as follows:

     1.  Prior to pursuing any remedy available to Tenant under the Lease
and/or the Chilled Water Agreement, at law or in equity as a result of any
failure of Landlord to perform or observe any covenant, condition, provision or
obligation to be performed or observed by Landlord under the Lease and/or that
certain chilled water service agreement, of even date herewith, executed by
Tenant, as "Supplier", and Landlord, as "Customer" (the "Chilled Water
Agreement") (any such failure hereinafter referred to as a "Fitzgerald's
Default"), Tenant shall: (a) provide Lender with a notice of Fitzgerald's
Default specifying the nature thereof and the section of the Lease or the
Chilled Water Agreement under which same arose, and (b) allow Lender thirty
(30) days following receipt of such notice of Fitzgerald's Default to cure the
same, provided, however, that, if such Fitzgerald's Default is not readily
curable within such thirty (30) day period, Tenant shall give Lender such
additional time as Lender may reasonably need to cure such Fitzgerald's Default
so long as Lender is diligently pursuing a cure, Tenant shall not pursue any
remedy available to it as a result of any Fitzgerald's Default unless Lender
fails to cure same within the time period specified above.

     2.  Tenant covenants with Lender that the Lease and the Chilled Water
Agreement shall be subject and subordinate to the lien and all other provisions
of the Mortgage and the other documents evidencing or securing the loan secured
by the Mortgage (the "Other Loan Documents") and to all modifications and
extensions thereof, to the full extent of all principal, interest and all other
amounts secured thereby. Without limiting the generality of the foregoing
subordination provision, Tenant hereby agrees that any of its right, title and
interest in and to

                                       1

<PAGE>   2
condemnation awards (or other similar awards arising from eminent domain
proceedings) with respect to condemnation (or similar taking) of any of the Real
Estate, shall be subject and subordinate to Lender's right, title and interest
in and to such awards, except to the extent of any such award specifically
allocated to the value of Tenant's personal property, trade fixtures installed
by Tenant, at Tenant's cost, and/or other improvements installed by Tenant, at
Tenant's cost, located thereon.

     3.   Tenant acknowledges that Landlord has collaterally assigned to Lender
all leases affecting the Real Estate, including the Lease, and the rents due
and payable under such leases, in connection therewith, Tenant and Landlord
agree that, upon receipt of a demand by Lender for direct payment to Lender of
the rents due under the Lease, Tenant shall honor such demand and make all
subsequent rent payments directly to Lender, and Landlord waives all rights to
such rent payments in such event.

     4.   Lender agrees that so long as Tenant is not in default under the
Lease and/or the Chilled Water Agreement:

          (a)  Tenant shall not be named or joined as a party in any suit,
     action or proceeding for the foreclosure of the Mortgage or the enforcement
     of any rights under the Mortgage; and

          (b)  The possession by Tenant of the Real Estate and Tenant's rights
     thereto shall not be disturbed, affected or impaired by, nor will the Lease
     or the term thereof be terminated or otherwise materially adversely
     affected by (i) any Suit, action or proceeding for the foreclosure of the
     Mortgage or the enforcement of any rights under the Mortgage, or by any
     judicial sale or execution or other sale of the Real Estate, or any deed
     given in lieu of foreclosure, or (ii) any default under the Mortgage.

     5.   If Lender or any future holder of the Mortgage shall become the owner
of the Real Estate by reason of foreclosure of the Mortgage or otherwise, or if
the Real Estate shall be sold as a result of any action or proceeding to
foreclose the Mortgage or transfer of ownership by deed given in lieu of
foreclosure, the Lease and the Chilled Water Agreement shall continue in full
force and effect, without necessity for executing any new lease, as a direct
lease between Tenant and the new owner of the Real Estate as "landlord" upon all
the same terms, covenants and provisions contained in the Lease (subject to the
exclusions set forth in subparagraph (b) below), or executing a new chilled
water agreement and in such event,

          (a)  Tenant shall be bound to such new owner under all of the terms,
     covenants and provisions of the Lease and the Chilled Water Agreement for
     the remainder of the term thereof (including the extension periods, it
     Tenant elects of has elected to exercise its options to extend the term),
     and, upon Tenant's receipt of written notice from the former and new owner
     as to a change in ownership of the Real Estate, Tenant hereby agrees to
     attorn to such new owner and to recognize such new owner as "landlord"
     under the Lease and to recognize such new owner as "customer" as long as
     there exists no Customer Default under the Chilled Water Agreement at the
     time of the receipt of said written notice;

                                       2
<PAGE>   3
          (b)  Such new owner shall be bound to Tenant under all of the terms,
     covenants and provisions of the Lease and the Chilled Water Agreement for
     the remainder of the term thereof (including the extension periods, if
     Tenant or Customer, as applicable, elects or has elected to exercise its
     options to extend the term); provided, however, that such new owner shall
     not be:

               (i)    liable for any act or omission of any prior landlord
          (including Landlord) or any prior customer (including Customer) that
          is not then continuing under the Lease and the Chilled Water
          Agreement; provided, however, that Tenant's sole remedy against Lender
          with respect to any act or omission of any prior landlord (including
          Landlord) that is then continuing under the Lease and the Chilled
          Water Agreement shall be to assert against Lender any offsets of rent,
          if any, or other defenses which Tenant has against any landlord under
          the Lease and/or against any customer under the Chilled Water
          Agreement (including Landlord) (subject to the limitations set forth
          in clause (ii) below);

               (ii)   subject to any offsets or defenses which Tenant has
          against any prior landlord (including Landlord) or any prior customer
          (including Customer) unless Tenant shall have provided Lender with (A)
          notice of the Fitzgerald's Default that gave rise to such offset or
          defense and (B) the opportunity to cure the same, all in accordance
          with the terms of Section 1 above;

               (iii)  bound by any base rent, additional rent or any other
          amounts payable under the Lease which Tenant might have paid in
          advance for more than the current month to any prior landlord
          (including Landlord), excluding, however, any offsets or rent credits
          pursuant to the terms of the Chilled Water Agreement;

               (iv)   liable to refund or otherwise account to Tenant for any
          security deposit not actually paid over to such new owner by Landlord;

               (v)    bound by any amendment or modification of the Lease and
          the Chilled Water Agreement made without Lender's consent;

               (vi)   bound by, or liable for any breach of, any representation
          or warranty or indemnity agreement contained in the Lease and/or the
          Chilled Water Agreement or otherwise made by any prior landlord
          (including Landlord) or by any prior customer (including Customer);

               (vii)  liable for the payment of any allowance or other amount

          the Landlord under the Lease and/or the Customer under the Chilled
          Water Agreement; or

               (viii) liable for any breach of the Lease by any successor
          landlord or for any breach of the Chilled Water Agreement by any
          successor customer except during any period that Lender is the
          landlord under the Lease or a customer under the Chilled Water
          Agreement.

                         CHILLED WATER SERVICE AGREEMENT

        THIS CHILLED WATER SERVICE AGREEMENT is dated as of December 10, 1999,
by and between e.three CUSTOM ENERGY SOLUTIONS, LLC, a Nevada limited-liability
company (the "Supplier"), and the customer (the "Customer") identified on the
Cover Page (this and all other capitalized terms used in this Agreement shall
have the meanings ascribed to those terms in Appendix A attached to this
Agreement).

                                    RECITALS:

        A.      Customer possesses an interest in the Premises, which interest
                is described more fully on the Cover Page.

        B.      Customer desires to purchase from Supplier, and Supplier desires
                to provide to Customer, chilled water service, at the delivery
                point, chilled water to meet the customers chilled water needs
                in the Premises, on the terms and subject to the conditions set
                forth in this Agreement.

        C.      Customer has acknowledged the possibility that it will file a
                Chapter 11 Petition during the Initial Term.

        D.      Customer has fully evaluated the benefits it would continue to
                derive under this Agreement after filing a Chapter 11 Petition,
                and has determined that it would be in the best interest of
                Customer to assume this Agreement under Section 365(a) during
                the administration of its Reorganization case.

        E.      Customer and Supplier consider this Agreement and Lease
                Agreement to be integral components of the overall contractual
                relationship between them, and neither Customer nor Supplier
                would be willing to enter into this Agreement without also
                entering into the Lease Agreements and having both agreements
                assumed by Customer under Section 365(a) during the
                administration of its Reorganization Case.

        F.      Customer and Supplier are entering into the Agreement based on
                Customer's agreement to assume the Lease Agreement, as well as
                this Agreement, in a timely manner under Section 365(a) during
                the administration of its reorganization Case.

        NOW, THEREFORE, for good and valuable consideration, the receipt and
        sufficiency of which are hereby acknowledged, Supplier and Customer
        agree as follows:

        1A. The Customer agrees that it will purchase all of its future chilled
        water requirements for the Premises from the Supplier and shall provide
        the Supplier with not less than thirty (30) days prior written notice of
        any expansion of the Premises or the construction of new Premises,
        structures or other facilities owned, leased or operated by the Customer
        that will require additional chilled water services. In the event that
        any additional Customer requirement for

                                       -2-

<PAGE>   10

        chilled water requires modification, expansion or improvements to the
        Facility, taking into account all obligations of Supplier to provided
        chilled water, Supplier, in Supplier's sole and absolute discretion, may
        reject Customer's request for additional chilled water service and this
        Agreement, as amended from time to time, shall continue in full force.

        1B. Chilled Water Service. Supplier agrees to supply Customer with
        chilled water service up to the Contract Capacity. The specifications
        for such service, including the temperature are set forth in the
        Installation, Operation and Maintenance ("IOM") Specifications on
        Exhibit D. The chilled water provided to Customer pursuant to this
        Agreement shall be used by Customer exclusively to reduce the ambient
        temperature within the Premises. Customer shall be responsible for and
        control the temperature levels of all space within the Premises as set
        forth on Exhibit D.

        2. Term.

                2.1 Commencement Date. The Commencement Date shall be the date
        on which Supplier is ready and able to begin supplying Customer with the
        chilled water service in accordance with the terms of this Agreement,
        provided that such date shall not be later than the Projected
        Commencement Date unless otherwise agreed by Supplier and Customer. If
        the Commencement Date fails to occur by September 1, 2000 for any reason
        other than the occurrence of a Force Majeure Event or a delay caused by
        Customer, then Customer may terminate this Agreement upon not less than
        five days prior written notice to Supplier given at any time thereafter
        and prior to the earlier of the Commencement Date or the 60th day
        following the Projected Commencement Date; however, such failure shall
        not constitute a Supplier Default and Customer's sole remedy as a result
        of such failure shall be the termination of this Agreement as aforesaid.

                2.2 Initial Term. The Initial Term of this Agreement commences
        on Commencement Date and continues for the period specified on the Cover
        Page, unless terminated earlier pursuant to the terms of this Agreement.

        3. Charges and Adjustments.

                3.1 Monthly Contract Capacity Charge. Customer shall pay to
        Supplier monthly during the term of this Agreement the Contract Capacity
        Charge for Supplier's undertaking to supply chilled water service up to
        the Contract Capacity.

                3.2 Consumption Charge. Customer shall pay to Supplier the
        monthly Consumption Charge for chilled water service actually consumed
        by Customer during such month.

                3.3 Facility Charge. Customer shall pay to Supplier the monthly
        Facility Charge for connection to the Facility used by the Supplier to
        provide chilled water service to the Customer for the first ten (10)
        years of the Initial Term, after which time the Facility Charge is

                                      -3-
<PAGE>   11

no longer due.

        3.4 Adjustments.

                3.4.1 Contract Capacity Charge. On each annual anniversary of
        the Commencement Date, the Contract Capacity Charge shall be increased
        to the sum of the following:

                (i)     the initial Contract Capacity Charge, plus

                (ii)    the product of (A) the initial Contract Capacity Charge,
                        multiplied by (B) the percentage increase, if any, in
                        the Consumer Price Index from the calendar month
                        immediately preceding the month in which the
                        Commencement Date occurs to the calendar month
                        immediately preceding the month in which the adjustment
                        to the Contract Capacity Charge is to occur, but in no
                        event to exceed three percent (3%) per annum.

                (iii)   If during any one-hour period during the term of this
                        Agreement, the Customer's requirement for chilled water
                        exceeds the Contract Capacity then in effect, then for
                        the next 3 (three) months the Contract Capacity and
                        Contract Capacity Charge shall be adjusted to an amount
                        equal to the Customer's peak use ("Temporary Demand
                        Adjustment"). At the expiration of such three (3) month
                        period, and provided that Customer's peak use has not
                        exceeded the Contract Capacity at any time during such
                        three (3) month period, the Temporary Demand Adjustment
                        shall expire and the Customer's Contract Capacity and
                        Contract Capacity Charge shall revert to the amounts in
                        effect immediately prior to the Temporary Demand
                        Adjustment, subject, however, to continuing adjustments
                        pursuant to this Agreement. In the event that the
                        Customer's actual capacity requirement exceed Contract
                        Capacity more than three (3) times within twelve
                        consecutive calendar month, the Contract Capacity and
                        Contract Capacity Charge shall be adjusted to the
                        highest actual capacity requirement within the preceding
                        twelve calendar months.

        The foregoing adjustment shall in no event result in a decrease in the
        Contract Capacity Charge in any year. The Contract Capacity Charge, if
        adjusted as aforesaid, shall remain unchanged until it is adjusted again
        pursuant to the terms of this Section or Section 3.4 below.

                                      -4-
<PAGE>   12

                3.6 Post-Filing-Payment Obligations. Any payment obligations
        which Customer incurs under this Agreement during the pendency of a
        Reorganization Case shall be deemed administrative expenses under
        Section 503(b)(1) in such Reorganization Case.

        4. Payment Terms.

                4.1 Invoices. Beginning on the Commencement Date, Supplier shall
        deliver to Customer monthly invoices reflecting all amounts then owing
        by Customer. The Contract Capacity Charge and the Facility Charge shall
        be prorated for partial first and last months within the term of this
        Agreement and shall be due and payable each month in advance. The
        Consumption Charge shall be due and payable each month in arrears.
        Payment shall be due in full, on or before the 30th day following the
        date of each invoice. Customer shall not be permitted to setoff any
        amounts owing by Customer to Supplier against any amounts owing by or
        claimed to be owing by Supplier to Customer or otherwise reduce any
        amounts owing by Customer to Supplier; provided, however, that if
        Customer provides Supplier with written notice of its good faith belief
        that a Consumption Charge set forth on an invoice from Supplier is
        incorrect within fifteen (15) days after receipt of such invoice, then
        Customer may withhold the payment of the disputed portion of such
        Consumption Charge; provided, however, that at no time may Customer
        withhold payment of Consumption Charges exceeding $5,000 in the
        aggregate, nor may Customer withhold payment of any amounts that are not
        in dispute. Notwithstanding the foregoing, as long as Customer is the
        landlord under that certain Lease dated as of December 10, 1999 between
        Customer, as landlord, and Supplier, as tenant and its permitted
        assignees (as amended, restated, modified or supplemented and in effect
        from time to time, the "Lease"), Customer may offset any amounts due
        hereunder in satisfaction of any "Rent" (as defined in the Lease) which
        is due under the Lease. If Customer fails to pay any portion of the
        Consumption Charges pursuant to the terms of the penultimate preceding
        sentence, the parties shall proceed to resolve such dispute pursuant to
        Section 15.14, and no Customer Default shall be deemed to exist because
        of such failure of payment during such period. Upon resolution of such
        dispute pursuant to Section 15.14, Customer shall promptly (and in any
        event within fifteen (15) days following the resolution of such
        dispute), pay any amount determined to be owing to Supplier in respect
        of such dispute. In the event that resolution of such dispute
        establishes that Supplier owes any additional amount to Customer beyond
        the amount which has been withheld pending resolution of such dispute,
        Supplier shall promptly (and in any event within fifteen (15) days
        following the resolution of such dispute) pay such amount to Customer.

                4.2 Default Rate Interest. (i) Any amounts owing by Customer to
        Supplier pursuant to the terms of this Agreement and not paid when due
        (or, if applicable pursuant to resolution of a dispute as provided in
        Section 4.1 and 15.14, within five Business (5) days after resolution of
        such dispute) shall thereafter bear interest until paid at a rate equal
        to the lesser of one and one-half percent (1.5%) per month or the
        highest rate permitted by law, whichever is less, and such interest
        shall be due and payable upon receipt of Supplier's invoice. Payment of
        such interest is not Supplier's sole remedy for the failure of Customer
        to make timely payments

                                      -6-
<PAGE>   13

        under this Agreement. All such interest shall be calculated using a year
        of 365 or 366 days (as applicable) and actual days elapsed.

                (ii) Any amounts owing by Supplier to Customer pursuant to the
        terms of the final sentence of Section 4.1 and not paid within five
        Business (5) days after resolution of the applicable dispute shall
        thereafter bear interest until paid at a rate equal to the lesser of one
        and one-half percent (1.5%) per month or the highest rate permitted by
        law, whichever is less, and such interest shall be due and payable upon
        receipt of Customer's invoice. All such interest shall be calculated
        using a year of 365 or 366 days (as applicable) and actual days elapsed.

         5. Installation, Maintenance and Ownership of Energy Transfer Station,
            Connection Equipment and Customer Cooling Equipment.

                5.1 Installation of Equipment. Supplier shall install the
        Equipment in accordance with the IOM Specifications. Customer shall
        cooperate with Supplier to the extent necessary to facilitate the
        installation of the Equipment in a timely, safe and efficient manner.
        The Energy Transfer Station shall remain the personal property of
        Supplier and shall not be deemed a fixture of the Premises.

                5.2 Location of Equipment. Customer shall provide a safe and
        secure space within the Premises that is reasonable and appropriate for
        the installation, inspection, testing, servicing, maintenance,
        operation, replacement and removal of the Equipment, which space shall
        include the location(s) described in the IOM Specifications and be
        satisfactory to Supplier.

                5.3 Maintenance of Energy Transfer Station. Supplier shall
        maintain the Energy Transfer Station during the term of this Agreement,
        at Supplier's sole cost and expense, in accordance with IOM
        Specifications, provided that if the Energy Transfer Station is damaged
        or destroyed as a result of the acts of Customer or its agents,
        employees, tenants, customers, contractors or other Persons for whom
        Customer is responsible, then Customer shall be liable for the cost of
        the required repair or replacement.

                5.4 Connection Equipment; Customer Cooling Equipment. Customer
        shall maintain the Connection Equipment and the Customer Cooling
        Equipment during the term of this Agreement, at Customer's sole cost and
        expense, unless Customer has executed a separate agreement with Supplier
        to provide such maintenance.

        6. Removal of Refrigerants and Existing Chiller Equipment

                6.1 Refrigerants. If Customer requests Supplier to remove the
        Refrigerants from the Premises, and if Supplier notifies Customer in
        writing that it has agreed to do so, Supplier shall remove said
        Refrigerants within 90 days after the date of Supplier's notice, at no
        cost to Customer.

                                      -7-
<PAGE>   14

                6.2 Existing Chiller Equipment. If Customer requests Supplier to
        remove the Existing Chiller Equipment from the Premises, and if Supplier
        notifies Customer in writing that it has agreed to do so, Supplier shall
        remove the Existing Chiller Equipment from Premises within 180 days
        after the date of Supplier's notice, at no cost to Customer.

                6.3 Removal of Refrigerants and Existing Chiller Equipment. If
        Supplier is not requested by Customer to remove the Refrigerants and
        Existing Chiller Equipment pursuant to Sections 6.1 and 6.2 above, or if
        Supplier has been requested to remove the same but does not elect to do
        so, then Customer shall be required to remove the Refrigerants and the
        Existing Chiller Equipment from the Premises on or before the First
        anniversary of the Commencement Date. Customer hereby agrees that if
        chilled water service is being provided by Supplier in accordance with
        the terms of this Agreement, Customer shall not use the Existing Chiller
        Equipment (prior to its removal) to provide cooling service for the
        Premises without Supplier's prior written consent.

                6.4 Title. Customer hereby covenants that upon Supplier's
        removal of the Refrigerants and/or Existing Chiller Equipment pursuant
        to Sections 6.1 and 6.2, title to the Refrigerants and/or Existing
        Chiller Equipment shall pass to Supplier free and clear of all rights of
        and liens and other claims by Customer and other third parties, and
        Supplier shall be entitled to retain all proceeds received upon the
        disposition of such Refrigerants and/or Existing Chiller Equipment.

                6.5 New Equipment. Within fourteen (14) days after the Effective
        Date of the Lease, Supplier shall at Supplier's sole cost and expense
        procure a new Lockinvar Boiler (the "Boiler") for Customer. Customer
        shall be responsible for ordering and installing the Boiler and Customer
        shall be the owner of the Boiler.

        7. Rights of Access.

                7.1 Generally. Commencing on the date of this Agreement,
        Supplier and its employees, agents, contractors and representatives
        shall have a non-exclusive right of access to and through the Premises
        at all times to the extent reasonably necessary for the convenient and
        efficient exercise and performance of Supplier's rights, duties and
        obligations under this Agreement, including the installation, testing,
        maintenance, operation, repair, replacement and removal of the Equipment
        and maintenance and operation of the Customer's Existing Chiller
        Equipment. Supplier agrees to coordinate such activities with Customer
        so as to minimize disruption to Customer's business to the extent
        reasonably practicable.

                7.2 Protection of Energy Transfer Station. Neither Customer nor
        its agents, employees. tenants, customers, contractors or other Persons
        under its control shall authorize or permit any Person (other than a
        duly authorized employee or agent of Supplier) to operate, maintain,
        alter or otherwise have access to the Energy Transfer Station, any
        component of the Energy Transfer Station or other property of Supplier
        located on or in the Premises, or to break

                                      -8-
<PAGE>   15

        or replace any seal or lock of Supplier, or to alter or interfere with
        the operation of meters or Supplier's connection or metering equipment,
        or any other equipment (other than the Connection Equipment) installed
        by Supplier on the Premises. Subject to the foregoing sentence, Customer
        and its agents, employees, tenants, customers, contractors and any other
        Persons under its control may have access to the portions of the
        Premises containing the items referred to in the foregoing sentence for
        reasonable inspection thereof and for other unrelated purposes;
        provided, however, that if at any time Customer reasonably believes that
        action with respect to the aforementioned equipment or property is
        necessary to prevent imminent harm to persons or property, then such
        access shall be permissible if and only if Customer takes only those
        actions with respect to such equipment or property, as are reasonably
        necessary to prevent said imminent harm and Supplier is promptly
        notified of such access and other action taken by Customer.

        8. Insurance Requirements; Financial information. The respective
        insurance requirements for Supplier and Customer are set forth in
        Exhibit B attached hereto, and the insurance described in Exhibit B
        shall be maintained throughout the term of this Agreement. The liability
        of each party under this Agreement to the other party shall not be
        diminished by the insurance limitations set forth in said Exhibit B. All
        insurance policies required by this Section shall provide that such
        policies may not be canceled or terminated without 30 days prior written
        notice to both Customer and Supplier.

        9. Events of Default

                9.1 Supplier Defaults.

                        9.1.1 Performance Failures and Service Default. A
                "Performance Failure" shall occur if, at any time after the
                Commencement Date and for any reason other than a Force Majeure
                Event or as permitted by Sections 10.1 and 10.2 hereof, (i)
                Supplier shall fail to provide chilled water service as required
                by this Agreement up to a lesser of the Contract Capacity or the
                Tons of chilled water service then required by Customer and (ii)
                such failure shall continue for a period of six (6) consecutive
                hours or longer and (iii) during such period Customer is ready,
                willing and able to receive such chilled water service and (iv)
                Supplier's failure is not otherwise the result of Customer's
                acts or omissions or those of its agents, employees, tenants,
                customers or contractors or of any other Persons for whom
                Customer is responsible or over which Customer has control.
                Promptly upon becoming aware of a Performance Failure (whether
                by notice thereof from Customer or by Supplier's monitoring of
                its systems or otherwise) Supplier shall:

                        (i) immediately seek to determine the cause of such
                Performance Failure and shall advise Customer of Supplier's
                conclusions as to such cause as quickly as possible and provide
                Customer with a corrective action plan;

                        (ii) commence implementation of such corrective action
                plan,

                                      -9-
<PAGE>   16

                using all reasonable efforts to correct or cure such Performance
                Failure in the shortest period of time which is reasonable in
                the circumstances (taking into account the nature and cause of
                the Performance Failure);

                        (iii) if Supplier believes that correcting or curing
                such Performance Failure requires or can reasonably be
                anticipated to last more than eight (8) consecutive hours, and
                Supplier and Customer agree that the Premises cannot be operated
                in a reasonably normal manner due to such ongoing Performance
                Failure, Supplier shall initiate (at Supplier's expense)
                procuring of substitute cooling services to be brought to the
                site and put into operation as quickly as possible.

        If any Performance Failure, which is not cured by Supplier as set forth
        in Section 9.1.1 (iii) above, continues for an additional period of
        seventy-two (72) consecutive hours or more, it shall thereupon be deemed
        a "Service Default."

                9.1.2. Supplier Defaults. The occurrence at any time of any of
        the following events shall constitute a "Supplier Default":

                (i) a Service Default; or

                (ii) the failure of Supplier to perform or cause to be performed
        any obligation required to be performed by Supplier under this Agreement
        other than a Service Default; provided, however, that if such failure by
        its nature can be cured, then Supplier shall have a period of 30 days
        after written notice from Customer of such failure to cure the same and
        a Supplier Default shall not be deemed to exist during such period, and
        provided further, that if Supplier commences to cure such failure during
        such period and is diligently and in good faith attempting to effect
        such cure, said period shall be extended for 30 additional days.

        9.2 Customer Default. The occurrence at any time of any of the following
        events shall constitute a "Customer Default":

                9.2.1 Failure to pay. The failure of Customer to pay any amounts
        owing to Supplier under this Agreement on or before the 30th day
        following the date when due and payable (or, if such amount has been
        determined to be payable pursuant to resolution of a dispute in
        accordance with Sections 4.1 and 15.14. within five (5) business days
        after resolution of such dispute.).

                9.2.2 Failure to Perform Other Obligations. The failure of
        Customer to perform or cause to be performed any other obligation
        required to be performed by Customer under this Agreement; provided,
        however, that if such failure by its nature can be cured, then Customer
        shall have a period of 30 days after written notice from Supplier of
        such failure to cure the same and a Customer Default shall not be deemed

                                      -10-
<PAGE>   17

                to exist during such period, and provided further, that if
                Customer commences to cure such failure during such period and
                is diligently and in good faith attempting to effect such cure,
                said period shall be extended for 30 additional days.

        10. Planned Maintenance; Other Service Interruptions.

                10.1 Planned Maintenance. Supplier shall have the right to
        interrupt or reduce Customer's chilled water service for a reasonable
        duration, (which shall not exceed eight (8) consecutive hours unless
        agreed upon in advance by Customer), upon prior notice to Customer, for
        the purpose of performing ordinary maintenance, repairs, replacements,
        connections or changes (on or off the Premises) of or to the Energy
        Transfer Station or any other equipment or apparatus which is required
        by good engineering and operating practices or by manufacturers'
        specifications. Supplier shall diligently attempt to restore service as
        soon as is reasonably possible and, in order to minimize interference
        with the normal operations of the Premises, Supplier shall coordinate
        with Customer to schedule such interruptions and reductions during
        non-summer months and during non-peak business hours (11:00 p.m. to 7:00
        a.m.) to the extent reasonably practicable.

                10.2 Other Interruptions. Supplier shall have the right to
        interrupt or reduce Customer's chilled water service for a duration
        determined necessary by Supplier, in its good faith judgment, without
        prior notice to Customer, if (i) a Force Majeure Event has occurred that
        causes or requires such interruption or reduction of such service, or
        (ii) the Customer Cooling System, the Connection Equipment or the
        Premises has become dangerous or defective in Supplier's good faith
        judgment and, as a result thereof, Supplier believes that such
        interruption or reduction is necessary to prevent injury to other
        Persons or damage to or destruction of property, including but not
        limited to, any component of the Energy Transfer Station or Supplier's
        other equipment and piping or to prevent the interruption or reduction
        of Supplier's service to its other customers. In the event of any such
        interruption or reduction of service, Supplier shall diligently attempt
        to restore service as soon as it is reasonably possible in the
        circumstances. Supplier shall notify Customer of the interruption, the
        anticipated duration of the interruption and the reason therefore as
        soon as possible after the interruption or reduction.

        11. Force Majeure Events. If either party to this Agreement is prevented
        from or delayed in performing any of its obligations under this
        Agreement by reason of a Force Majeure Event, such party shall notify
        the other party in writing as soon as practicable after the onset of
        such Force Majeure Event and shall be excused from the performance of
        its obligations under this Agreement to the extent such Force Majeure
        Event has interfered with such performance. The party whose performance
        under this Agreement is prevented or delayed as the result of a Force
        Majeure Event shall use reasonable efforts to remedy its inability to
        perform. If a party's failure to perform its obligations under this
        Agreement is due to a Force Majeure Event, then such failure shall not
        be deemed a Supplier Default or a Customer Default. If Supplier fails to
        provide the chilled water service required by this Agreement due to the
        occurrence of a Force Majeure Event, Customer shall be entitled to an
        abatement of the Contract Capacity Charge and the Consumption Charge
        from the date on which such failure commenced through the date

                                      -11-
<PAGE>   18

on which such failure ceases or this Agreement is terminated, and the term of
this Agreement shall be extended by a period of time equal to the period of such
abatement.

        12. Remedies Following Default.

                12.1 Customer's Remedies upon Occurrence of a Performance
        Failure Default. If a Performance Failure occurs and Supplier and
        Customer agree that the Premises cannot be operated in a reasonably
        normal manner due to such ongoing Performance Failure, and if Supplier
        does not thereupon initiate procuring of substitute cooling services to
        be brought to the site and put into operation as quickly as possible,
        then Customer, at Supplier's expense, shall have the right to take any
        action reasonably intended to procure substitute cooling services to be
        brought to the site and put into operation as quickly as possible to
        correct or cure such failure. In the event that such Performance Failure
        becomes a Service Default, the foregoing shall be in addition to the
        rights of Customer provided for a Service Default. All costs and
        expenses incurred by Customer in procuring such cooling services may be
        deducted from any sums owing Supplier for the Contract Capacity Charge
        and the Consumption Charge.

                12.2 Customer's Remedies Upon Occurrence of a Supplier Default.

                        12.2.1 Abatement. If a Service Default described in
                Section 9.1.2 above has occurred, Customer shall be entitled to
                an abatement of the Contract Capacity Charge and the Consumption
                Charge from the date on which such Service Default commenced
                through the date on which such Service Default ceases to exist,
                or (if applicable) is waived or this Agreement is terminated.
                Notwithstanding anything in this Agreement, at law or in equity
                to the contrary, abatement of the Contract Capacity Charge and
                the Consumption Charge specified in this Section 12.2.1 shall be
                Customer's sole and exclusive remedy upon the occurrence of a
                Service Default described in Section 9.1.2 above, subject to
                Customer's termination right under Section 12.2.2 below (and in
                the event of such termination, the remedies set forth in Section
                12.2.3 below).

                        12.2.2 Termination. If a Supplier Default has occurred
                and continues for not less than thirty (30) consecutive days,
                then Customer at any time thereafter may give Supplier a notice
                of Customer's intent to terminate this Agreement, and if such
                written notice is given and Supplier fails to correct or cure
                such conditions by the close of business on the fifth (5th) day
                after the date on which Customer gives Supplier such written
                notice of Customer's intent to terminate this Agreement as a
                result of such Supplier Default, then this Agreement shall
                terminate and be of no further force or effect as of the close
                of business on such fifth (5th) day; provided, however, that in
                the case of a Service Default which cannot be cured within
                thirty (30) days and Supplier has procured substitute cooling
                services for the Premises, Customer may not terminate this
                Agreement so long as Supplier is diligently and in good faith
                attempting to cure such Service Default.

                                      -12-
<PAGE>   19

                12.2.3 Other Rights and Remedies.

        (i)     The remedies provided herein for a Performance Failure shall be
                the exclusive remedies of Customer for such failure, unless and
                until the same becomes a Service Default.

        (ii)    If any Service Default has occurred, then Customer's sole remedy
                shall be abatement of charges as provided in Section 12.2.1,
                unless such Service Default continues for a period permitting
                Customer to terminate this Agreement pursuant to Section 12.2.2,
                in which case, upon such termination, Customer may pursue any

                occurred and continues for a period permitting Customer to

                remedies available to it at law or in equity, subject, however,
                to the limitations set forth in Section 12.4 below.

        period.

                12.3.2 Termination. If a Customer Default has occurred and

from Customer on account of a Customer Default) or other special or
consequential damages, all claims for which are hereby irrevocably waived by
Customer and Supplier. Notwithstanding the foregoing, third party claims against
either Supplier or Customer against which such party has a right of
indemnification pursuant to Section 14 below shall not be considered to be
consequential damages.

13. Effect of Termination of Agreement.

        13.1 Payment; No Further Obligations. Subject to Section 12.3 above,
upon the termination or expiration of this Agreement, any amounts then owing
under this Agreement by a party to this Agreement to other party to this
Agreement shall become immediately due and payable, and the then future

(other than the indemnity obligations set forth in Section 14 below). Such
termination shall not relieve either party from obligations accrued prior to the

the Premises, in which case Supplier shall have the right to do so within sixty
(60) days after such termination or expiration, and Customer shall provide
Supplier with access to the Premises as reasonably requested by Supplier to
allow Supplier to complete such removal, or (b) with Customer's written consent,
abandon any or all of such property to Customer and said property shall become
Customer's free and clear of any liens or encumbrances created by Supplier.

        14.1 Indemnification by Supplier. Supplier shall fully indemnify, save

Expenses incurred by such Customer Group Member, including reasonable attorneys'
fees and costs, in connection with or arising from any claim by a third party
for physical damage to or physical destruction of property, or death of or
bodily injury to any Person, caused by (i) the gross negligence or willful
misconduct of Supplier or its agents or employees or others under Supplier's
control, or (ii) a Supplier Default; provided, however, that nothing in this
Section is intended to modify the limitation of Supplier's liability set forth
in Sections 12.1 and 12.3 above.

        14.2 Indemnification by Customer. Customer shall fully indemnify, save
harmless and defend each Supplier Group Member from and against any and all

physical destruction of property, or death of or bodily injury to any Person,
caused by (i) the gross negligence or willful misconduct of Customer or its
agents or employees or others under Customer's control or (ii) a Customer
Default; provided, however, that nothing in this Section is intended to modify

under this Section 14 shall deliver to the Indemnitor a Claim Notice describing
the facts underlying its indemnification claim and the amount of such claim, if
known at the time. A notice describing any action at law or in equity involving
an Indemnified Party shall be delivered promptly to the Indemnitor after the
such Indemnified Party receives notice that such action or suit has commenced;
provided, however, that failure to deliver such notice as aforesaid shall not
relieve the Indemnitor of its obligations under this Section 14, except to the
extent that such Indemnitor has been prejudiced by such failure.

        14.4 Amount of Claim. The amount to which an Indemnified Party is
entitled under this Section 14 shall be determined by (i) a mutually
satisfactory written agreement between such Indemnified Party and the
Indemnitor, (ii) a final judgment or decree of any court of competent
jurisdiction, or (iii) any other means agreed upon by such Indemnified Party and
the Indemnitor.

        14.5 Defense of Action. If requested by an Indemnified Party, the
Indemnitor shall assume on behalf of the Indemnified Party, and conduct with due
diligence and in good faith, the defense of such Indemnified Party with counsel
reasonably satisfactory to the Indemnified Party; provided, however, that if the
Indemnitor is a defendant in any such action and the Indemnified Party believes
that there may be legal defenses available to it which are inconsistent with
those available to the Indemnitor, the Indemnified Party shall have the right to
select separate counsel to participate in the defense of such action at the
Indemnitor's expense. If any claim, action, proceeding or investigation arises
as to which the indemnity provided for in this Section 14 applies, and the
Indemnitor fails to assume the defense of such claim, action, proceeding or
investigation after having been requested to do so by the Indemnified Party,
then the Indemnified Party may, at the Indemnitor's expense, contest or, with
the prior written consent of the Indemnitor, which consent shall not be
unreasonably withheld, settle such claim, action, proceeding or investigation.
All costs and expenses incurred by the Indemnified Party in connection with any
such contest or settlement shall be paid upon demand by the Indemnitor.

        14.6 Survival of Provisions. The provisions of this Section 14 shall
survive the expiration or termination of this Agreement.

                                   EXHIBIT D

             Installation, Operation and Maintenance Specifications

The purpose of this exhibit is to outline the method and means of operating and
maintaining the Supplier's chilled water system that will deliver chilled water
service to the customer's premises:

a)    Supplier's Chilled Water System Overview

The provision of chilled water to the Customer's premises is based on the
establishment of a central chilled water plant located at 301 Fremont St.
that produces chilled water cooling energy for space cooling. The chilled water
is distributed to each Customer via supply and return Service Line(s) dedicated
to each Customer. The central chilled water plant primary piping and
Distribution Lines are both designed to provide chilled water on a variable-flow
(demand) basis. The Distribution Lines will be configured as hydraulically
decoupled from the central chilled water plant primary piping. The system will
be designed to operate such that the temperature differential or Delta T between
the central chilled water plant primary piping and the Distribution Lines is
maintained as close as possible to the chilled water plant design temperature
differential. This is used to ensure that the central chilled water plant is
used at the highest efficiency possible at any given load.

The chilled water system at each Customer will have a plate and frame heat
exchanger as part of the Energy Transfer Station (ETS). The plate and frame heat
exchanger transfers chilled water cooling energy from the Service Lines to the
Customer cooling system. The plate and frame heat exchanger prevents mingling of
the central chilled water plant cooling medium and the Customer cooling system
medium. Chilled water energy consumption and demand are metered at the service
entry point or point of demarcation of the Customer facility. The plate and
frame heat exchanger(s), energy meter(s), and associated controls will be
installed in the Customer Premises as a packaged unit, which, along with the
Energy Transfer Station, marks the point of demarcation between the Supplier and
the Customer cooling system. This interface point with the packaged equipment is
termed the Energy Transfer Station (ETS).

B)    Chilled Water Service Temperatures

The chilled water supply temperatures are specified as "entering" the Supplier
side of the Energy Transfer Station. The supplier will ensure that the chilled
water supply temperature will be within the range of 40 to 42(degree)F.

The Supplier anticipates that the Customer requires 45(degree)F leaving chilled
water temperature from the Customer side of the Energy Transfer Station. The
Supplier anticipates that the Customer will return chilled water to the Customer
side of the Energy Transfer Station at 55 - 59(degree)F.

<PAGE>   36

c)    Distribution System - General System Description

The Supplier will provide the chilled water services to the Customer from the
City Centre Chilled Water Plant. The chilled water distribution system is a
network of piping, pumps, and controls linking the chilled water source with the
Customer. The system is installed in the easement allocated using trenched
construction methods.

The distribution network will be designed to have a minimum cover of two (2)
feet over the Distribution Lines. The actual amount of cover will depend on
utility conflicts and Distribution Line servicing requirements. Typical piping
will be installed with approximately three feet of cover. In the majority of
cases, direct buried valves and vents will be installed on the cooling
distribution system. Drains will be installed either at valve chambers or at
separately built chambers, as necessary. Valves, vents, and drains will be
installed on-line and within the easements.

d)    Energy Transfer Station(s) (ETS) - General Description

The chilled water from the Supplier is circulated in the Distribution and
Service Lines from the central chilled water plant to the Energy Transfer
Station. The customer side of the Energy Transfer Station uses cooling energy as
needed to reduce the temperature of the Customer cooling system. The manner in
which the Customer uses chilled water cooling energy in its cooling systems has
no direct interconnect to the distribution system from the supplier. The
Customers cooling system is isolated from the chilled water Service and
Distribution Lines of the Supplier by way of a heat exchanger.

The interface point at which the energy exchange takes place and is measured as
it enters a Customer facility is referred to as the "Energy Transfer Station"
(ETS).

e)    Energy Transfer Station (ETS)

The ETS is a prefabricated unit including a plate and frame heat exchanger used
for the transfer of heat energy. The ETS usually consists of flat plate heat
exchangers for the chilled water, energy meters, control valves, and
thermometers. The Service lines, pipes that connect the Energy Transfer Station
with the Distribution Lines, are assembled on-site and will include isolating
valves, strainers, and pressure indicators. The Customer will be responsible for
connection of the Customer cooling system to the Customer side of the Energy
Transfer Station. The Supplier will coordinate the required specifications of
the Customer side of the Energy Transfer Station with the Customer.

The minimum space requirements for the installation of the ETS will be
approximately 250 Sq. Ft and the room will be dust free with ventilation.

<PAGE>   37

f)    Energy Metering

The consumption of chilled water cooling energy by the Customer will be measured
by an Energy Meter. The Energy Meter measures the flow of the entering and
leaving chilled water of the Energy Transfer Station In addition to measuring
flow, the Supplier side of the Energy Transfer Station is measured for, entering
and leaving chilled water temperatures. The Energy Meter will be able to
calculate the instantaneous energy demand, the peak energy demand, and total
usage/consumption to-date for billing purposes.

g)    Chilled Water Plant Equipment

The chilled water production system will use electric-driven, mechanical
chillers to generate cold water for distribution. The chillers will be
high-efficiency units. Each chiller will be a factory prepackaged and factory
witness tested unit that includes unit piping connections, controls,
instrumentation, and local control panel.

The chiller(s) condenser will be supplied with cooling water from cooling towers
located on the roof of the chilled water plant building. The towers will be
suitable for outdoor, all-weather operation. Each chiller would be equipped with
a dedicated evaporator circulation pump as well as a dedicated condenser water
circulation pump. The evaporator circulation pumps are required, as the central
chilled water plant primary piping and the Distribution Lines will be configured
as a hydraulically decoupled system. The cooling tower bank will be supplied
with makeup water from the makeup water system.

h)    Distribution Pumps

The chilled water will be distributed to the Distribution Lines by a set of
variable-speed/horizontal split-case, and standby fixed-speed pumps located in
the central chilled water plant. Control of the distribution pumps will be via
the chilled water plant's DDC control system based on the Distribution Lines
pressure differential.

i)    Plant Control System

The central plant will be controlled by a direct digital control system (DDC).
The DDC control system is based on a central chilled water plant serving all
customers from the central chilled water plant. The DDC control system will
allow the central chilled water plant to operate in automatic mode, or allow the
operator to operate selected equipment manually. The DDC control system will
monitor each system for faults, provide warning alarms, and initiate shutdowns
as required to protect the safety of the operating staff and to minimize damage
to the equipment. The DDC control system also will collect, calculate, and store
data pertaining to the energy produced or consumed at the central chilled water
plant. The DDC control system will also be used to collect and store energy
consumed values for billing purposes from each of the Customers receiving
chilled water service.

<PAGE>   38

j)    Equipment and Redundancy

The philosophy followed in establishing the amount of redundancy to be installed
is to ensure enough standby chilling capacity to satisfy the cooling
requirements of the Customer. Electric supply to the central chilled water plant
has been designed to include separate power feeds from different utility company
substations to the central chilled water plant

k)    Spare Parts

Onsite capital spare parts will not be required because complete spare units
will be installed for the chillers. The only items needed to be stored at the
plant are the consumable items such as chemicals, oils, belts, filter elements,
temperature instruments, pressure instruments, gaskets, pressure regulator
overhaul kits, etc.

                  the supplier based at its option upon (i) the supplier's meter
                  record immediately before and after the period of
                  interruption, (ii) past customer usage during a similar period

                  combination of these methods, and the customer will pay
                  invoices during such period based on the estimated
                  measurement. All billings based on estimated usage will
                  indicate the method of estimation employed.

        over, in and under the real property described on Exhibit "B" as
        Landlord Parcel ("Landlord Parcel") (i) for the purpose of providing
        access to Landlord's buildings, and (ii) to permit access for, and the
        construction, installation, maintenance, repair, security and
        replacement of, pipes, ducts, cables, conduit and other equipment and
        apparatus used or to be used by Tenant for the construction, operation
        and maintenance of the Facility and the Distribution System, and for
        installation of the Distribution System from the Facility to Fourth
        Street, which easements are depicted on Exhibit B-1.

                (c) Landlord hereby grants to Tenant and its successors and
        assigns an exclusive temporary easement in the real property in Clark
        County, Las Vegas, Nevada that is depicted on Exhibit B-2 ("Temporary
        Construction Easement"), for purposes of staging all construction
        activities related to the Facility and Distribution System. This
        easement shall terminate and expire upon completion of construction of
        the Facility and Distribution System.

        The easements granted in this Section 3.1, except with respect to the
easement granted in Section 3.1 (c) shall continue so long as this Lease remains
in effect and shall expire and be of no further force or effect upon the
expiration or termination of this Lease. Each easement granted under this Lease
shall exist by virtue of this Lease, without the necessity of or confirmation by
any other document, and shall run with the Premises. Upon the expiration,
termination (in whole or in part) or the release of any such easement in
accordance with the provisions of this Lease, the same shall be deemed to have
expired, or have been terminated or released without the necessity of
confirmation by any other document.

        Section 3.2 Term. The terms and conditions of this Lease, other than the
obligation of

                                       2
<PAGE>   51

Tenant to pay the Initial Base Rent, as defined below, shall be effective as of
the date of this Lease ("Effective Date"); subject, however, to Tenant's right
to terminate this Lease upon the failure of any condition precedent set forth in
this Lease or in Annex D attached hereto. The initial term of this Lease shall
be a period commencing on the date that all conditions set forth on Annex D,
attached hereto, are fully satisfied or waived by Tenant or the date Tenant
takes possession, whichever occurs first (the "Commencement Date") and, except
as otherwise provided in this Lease to the contrary, ending on the date that is
twenty (20) years following the Commencement Date (the "Initial Lease Term"),
subject to Section 3.3. below. The parties hereto shall execute a written
statement setting forth (i) that all conditions precedent are either waived or
satisfied, (ii) the Commencement Date and (iii) the expiration date of the Term
promptly after the same shall have been ascertained. The term of this Lease, as
the same may be extended or renewed, is referred to herein as the "Lease Term".

        Section 3.3 Renewal Options.

        (a) Landlord hereby grants to Tenant two (2) successive five (5) year
options to renew the term hereof (each a "Renewal Option") with respect to all
(but not less than all) of the Premises demised under or pursuant to this Lease
(the term of each Renewal Option is referred to as a "Renewal Term") commencing
as of the expiration date of the Initial Lease Term or any Renewal Term then in
effect, upon the following terms and conditions: (i) Tenant shall give Landlord
written notice of Tenant's election to exercise the Renewal Option not later
than six (6) months prior to the expiration date of the Initial Lease Term or
any Renewal Term then in effect; and

                (ii) No Tenant Default exists and is continuing on the date
        Tenant exercises the Renewal Option or on the expiration date of the
        Initial Lease Term or such Renewal Term then in effect, and this Lease
        has not been terminated on the date on which Tenant exercises the
        Renewal Option or on the proposed commencement date of the Renewal Term.

        (b) If Tenant timely and properly exercises the Renewal Option:

                (i) The Base Rent payable monthly for the Renewal Term shall be
        determined in accordance with Annex F;

                (ii) Tenant shall have no further options to renew the Lease
        Term beyond the expiration date of the last Renewal Term which becomes
        effective hereunder;

                (iii) Tenant shall accept the Premises at the commencement of
        each Renewal Term in its "as is" condition, and Landlord shall not be
        obligated to perform any leasehold improvement work in the Premises or
        give Tenant any allowance for any such work or any other purposes during
        or for any Renewal Term; and

                                       3
<PAGE>   52

                (iv) Except for the rate of Base Rent and except as otherwise
        provided herein, all of the terms, provisions, representations and
        warranties of this Lease shall remain the same and in full force and
        effect during each Renewal Term.

        (c) If Tenant exercises a Renewal Option, then, upon either party's
request Landlord and Tenant shall execute and deliver an amendment to this Lease
or a memorandum in recordable form reflecting the lease of the Premises by
Landlord to Tenant for the Renewal Term on the terms provided above, which
amendment or memorandum shall be executed and delivered within thirty (30) days
after Tenant exercises a Renewal Option.

        (d) Any unused Renewal Options shall automatically terminate and become
null and void upon the expiration or termination of this Lease.

        (e) Notwithstanding the foregoing, if Tenant shall fail to give any such
notice within the time limit set forth above, Tenant's right to exercise its
options shall nevertheless continue until thirty (30) days after Landlord shall
have given Tenant notice of Landlord's election to terminate such option, and
Tenant may exercise such option at any time until the expiration of said thirty
(30) day period.

        It is the intention of the parties to avoid forfeiture of Tenant's
rights to extend the Term under any of the options set forth in this Section 3.3
through inadvertent failure to give notice of exercise thereof within the time
limits prescribed. Accordingly, if Tenant shall fail to give notice to Landlord
of Tenant's election to extend the Lease Term for any of the aforesaid renewal
periods and if Landlord shall fail to give notice to Tenant of Landlord's
election to terminate Tenant's right to extend the Lease Term under the option
applicable thereto, then and so often as such event shall occur, the Term shall
be automatically extended from month to month upon all of the terms and
conditions then in effect, subject to Tenant's right under such option to extend
the Term for the remainder of the applicable Renewal Term covered thereby, and
subject to Landlord's right to place the thirty (30) day limit on such option by
a notice in the manner provided in this Section, and subject to adjustments in
the initial Base Rent as more specifically set forth in Annex E.

        Section 3.4 Acceptance of Premises; Environmental Matters;
Environmental Indemnity. Upon expiration of the Inspection Period and
satisfaction, in Tenant's sole and absolute discretion, of the conditions set
forth on Annex D, Tenant accepts the Premises and agrees that, other than as set
forth in this Lease, neither Landlord, nor any of Landlord's agents, has made
any oral or written representations or warranties with respect to the Premises
and Landlord has no obligation and has made no promises to remediate any
environmental condition of the Premises, or any part thereof, or to alter,
remodel, improve, repair or renovate the Premises or any part thereof, other
than as set forth on Exhibit D hereto.

        Notwithstanding the foregoing, Landlord hereby agrees to indemnify,
defend and hold Tenant harmless, from and against: (a) any Hazardous Material
located on the Premises solely as a result of the acts or omissions of the
Landlord at any time after the date hereof; or (b) any condition

                                       4
<PAGE>   53

of the Premises existing as of the date hereof, or which arises or occurs after
the date hereof solely as a result of the acts or omissions of the Landlord,
which violates any Hazardous Materials or Environmental Laws. Tenant hereby
agrees to indemnify, defend and hold Landlord harmless, from and against: (a)
any Hazardous Material located on the Premises as a result of the acts or
omissions of Tenant at any time after the date hereof; or (b) any condition of
the Premises which arises or occurs after the date hereof as a result of the
acts or omissions of Tenant, which violates any Hazardous Materials or
Environmental Laws. The provisions of this Section 3.4 shall survive the
expiration or termination of this Lease.

        Notwithstanding the Effective Date of this Lease or Tenant's
unwillingness to accept the Premises, Tenant shall not be liable or responsible
for any clean-up, remediation, reporting, evaluation, costs or fees, of whatever
nature, or any diminution in value of the Premises arising from or in connection
with any known or unknown Hazardous Material or violation of Environmental Laws
discovered or disturbed on, in, under or around the Premises during or as a
result of Tenant's due diligence examination of the Premises during the
Inspection Period and Landlord hereby agrees to indemnify, defend and hold
Tenant harmless, from and against any such loss, cost, fees (including
attorneys' fees and discovery costs), expense, liability, suit or proceeding
arising from or in connection with any Hazardous Material or violation of
Environmental Laws discovered or disturbed on, in, under or around the Premises
during or as a result of Tenant's due diligence examination of the Premises.
Tenant shall be entitled to approve or disapprove in good faith any legal
counsel or experts used in connection with Landlord's defense of Tenant. In the
event that Landlord and Tenant are unable to agree, in good faith, upon
acceptable legal counsel, Tenant may, in its sole and absolute discretion,
select its legal counsel the costs and fees for which legal counsel and defense
shall be paid directly by Landlord. Any amounts advanced by Tenant and not
reimbursed by Landlord within thirty (30) days following Landlord's receipt of
written demand therefore shall accrue interest at the rate of twelve percent
(12%) per annum until paid.

In case any action, suit or proceeding is brought against a party hereto by
reason of any such occurrence, at the indemnified party's option, the
indemnifying party shall, at the indemnifying party's sole cost and expense, by
counsel selected by the indemnifying party (which counsel must be reasonably
satisfactory to the indemnified party), defend such action, suit or proceeding,
or cause the same to be defended.

        Section 3.5 Quiet Enjoyment. Landlord covenants that Tenant shall have
quiet enjoyment of the Premises and further agrees that Landlord's activities
shall not have an adverse effect on Tenant's activities. For the purposes of
this paragraph, "adverse effect" means a materially detrimental effect on the
ownership, construction, maintenance, repair, or operation of the Facility or
the Distribution System.

Rent for each subsequent Lease Year shall be increased from time to time in
accordance with Annex E. Tenant's obligation to pay Rent shall commence on
January 1, 2000 or the date that Tenant takes possession of the premises,
whichever is later (the "Rent Commencement Date"). The parties hereto shall
execute a written statement setting forth the Rent Commencement Date promptly
after the same shall have been ascertained which statement may be combined with
the statement identified in Section 3.2.

        Section 4.2 Rent Payments. Base Rent shall be payable to Landlord, at
301 Fremont Street, Las Vegas, Nevada 89101 or at such other place as Landlord
may designate in writing to Tenant from time to time. All payments of Rent shall
be made in lawful money of the United States. Tenant's obligation to pay Base
Rent on or after the Rent Commencement Date shall, however, be subject to a
right of setoff in favor of Tenant for amounts payable by Fitzgeralds Las Vegas,
Inc., or its successor or assigns, to Tenant under any Chilled Water Service
Agreement between such parties in effect from time to time; provided, however,
that Tenant shall not offset any payment of Base Rent unless amounts payable
under any such Chilled Water Service Agreement are at least thirty (30) days
past due.

        Section 4.3 Net Lease. This Lease shall be a "net" lease and, commencing
on the Commencement Date and until the expiration or termination of this Lease,
Tenant shall be responsible for and pay all Impositions of any kind whatsoever
relating to the Premises and the Facility and any alterations, improvements and

such due diligence as is reasonably necessary with respect to the conditions set

Tenant the right to enter upon the Premises and Other Lands to construct,
operate and maintain the Facility and Distribution System. Tenant shall pay all
costs and expenses of obtaining the reports and surveys identified on Annex D,

Landlord's request, Tenant will provide Landlord with a copy of said reports and
surveys. Prior to entry upon the Premises and Other Lands, Tenant shall provide
to Landlord evidence of comprehensive general liability insurance in the amount
set forth on Exhibit E. It is the intent of the parties that Tenant shall not
have exclusive possession of the premises until the Commencement Date.

        Section 5.2 Use and Possession. Upon satisfaction or waiver by Tenant of
the

                                       6

described in Sections 3.2 and 4.1, Tenant shall with due diligence construct,
operate and maintain the Facility on the Premises to provide chilled water to
customers. The Facility shall be constructed within the boundary lines of the
Premises. The Facility and the Distribution System may include fiber optic cable
and conduit and related equipment installed by Tenant for use in connection with
providing and monitoring the chilled water service or for providing other
telecommunications services. Tenant understands that there are other
telecommunications facilities in and around casino/hotel and Tenant agrees not
to install or use any telecommunication equipment that interferes with the
operation of existing equipment in Landlord's casino/hotel. Title to the
Facility and to all of the personal property owned by Tenant and used in
connection with the construction, operation and maintenance of the Facility and

Landlord's lenders) at all times, except as otherwise provided elsewhere in this
Lease.

        Section 5.3 Signage. Landlord and Tenant will both display signage on
the exterior of the Facility. Tenant's signage will read "Nevada Power Services"
and will include its red logo, and will be placed on both the south and east
walls of the Facility. Tenant's signage must be of such size as to be easily
readable from the adjacent streets. Tenant will work with Landlord so that
Tenant's signage coordinates with and does not overpower Landlord's signage and
Landlord's casino/hotel. Tenant shall be responsible for all costs of
purchasing, installing and maintaining Tenant's signage. Landlord shall be
responsible for all costs of purchasing, installing and maintaining the Landlord
signage. Landlord signage shall not interfere with the operation or use of the
Facility and shall not require any material modification to the Facility.
Ownership and title to any Landlord signage shall remain with Landlord. Landlord
shall pay to Tenant the cost of any utilities used in connection with Landlord's
signage; provided, however, that in the event that Landlord fails or refuses to
maintain the Landlord signage or pay for such utilities used in connection
therewith, Tenant may cause such obligations to be performed or discharged and
upon receipt of written demand from Tenant, Landlord shall reimburse Tenant for
all reasonable costs in relation thereto. Landlord and Tenant shall agree on the
amount per month that Landlord shall pay Tenant for utilities used in operating
the signage. Tenant shall pay for the cost of purchasing, installing and
maintaining its signage. If Tenant fails or refuses to maintain its signage,
Landlord may cause such obligations to be performed or discharged and upon
written demand from Tenant, Landlord shall reimburse Tenant for all reasonable
costs in relation thereto.

        Section 5.4 Limitations on Use. Tenant shall not use the Premises for
any purpose other than a Chilled Water Distribution Facility. Landlord hereby
acknowledges and agrees, however, that Tenant may distribute and/or sell chilled
water services from the Facility to locations outside of the Premises and to
third Persons. Tenant shall not use or occupy the Premises, or permit the use or
occupancy of the Premises, in any manner or for any purpose which would:

                (a) violate any law, statute, ordinance or other federal, state
        or local governmental rule, regulation or requirement ("Applicable Law")
        including, without limitation, those with respect to hazardous or toxic
        materials, or the provisions of any applicable governmental permit or
        document related to the Facility or the Premises;

                                       7
<PAGE>   56

                (b) violate any reasonable safety or security regulation or
        policy of Landlord, as Landlord may from time to time adopt; provided,
        however that in no event shall any such rule, regulation or policy
        substantially or materially interfere with or restrict the operation or
        maintenance of the Facility or require Tenant to expend any substantial
        funds to comply with any such rule, regulation or policy, except as
        otherwise agreed to, in writing, by Tenant;

                (c) in any way cause an adverse effect on any of Landlord's
        activities or Landlord's use of Landlord's property (provided that the
        handling of interruptions of chilled water service to Landlord shall be
        exclusively addressed in a Chilled Water Service Agreement between
        Landlord and Tenant); or

                (d) cause the cancellation, ineffectiveness or increased premium
        of any fire or other insurance maintained or required hereunder to be
        maintained by Tenant or Landlord.

        Section 5.5 Construction of Improvements; Alterations.

        (a) Tenant's Work. For purposes of this Article 5, the term "Tenant's
Work" shall mean and refer to the design construction and installation of all
aspects of the Facility and Distribution System as described in detail in
Exhibit C hereto (such work being referred to herein as the "Tenant's Work").
Tenant shall be responsible for all cost associated with Tenant's work.

        (b) Landlord's Work. Any work to be performed by Landlord in connection
with the construction and development of the Facility and Distribution System is
described in detail in Exhibit D hereto (such work being referred to herein as
the "Landlord's Work"). Tenant shall pay to Landlord or reimburse Landlord for
the actual costs and fees incurred by Landlord in connection with Landlord
obtaining the permits and approvals described on Exhibit D except Tenant shall
have no obligation to pay or reimburse to Landlord any costs related to site
improvements or changes required of Landlord by the City of Las Vegas that have
been deferred from prior projects or that are required because of prior
construction or commitments by the Landlord. Any amounts advanced by Landlord
and not reimbursed by Tenant as provided herein shall accrue interest at the
rate of twelve percent (12%) per annum until paid. Tenant agrees to pay or
reimburse Landlord for said costs and fees upon receipt of Landlord's written
demand therefore. Tenant shall not be required to pay for any costs or fees
incurred by Landlord in connection with obtaining any permits or approvals for
(i) structural or cosmetic alteration to Landlord's hotel casino, other than
such alterations with respect to the inter-connection of the Facility to
Landlord's hotel casino, but exclusive of any work required to Landlord's
facility to bring such facility into compliance with current building, health or
safety codes or (ii) signage or any other lighting or decorative identifications
or displays.

        To enhance the aesthetics of the Premises, Landlord may install
landscaping in the areas surrounding the Facility ("Landlord Landscaping").
Landlord shall be responsible for all costs of

                                       8
<PAGE>   57

purchasing, installing and maintaining such Landlord Landscaping; provided that
upon completion of installation of the Landlord Landscaping, Tenant shall pay to
Landlord $15,000 towards the purchase and installation of the Landlord
Landscaping upon receipt of Landlord's invoice therefore. Landlord shall provide
a suitable water line from the Facility to permit irrigation of the Landlord
Landscaping. Landlord shall, at Landlord's sole cost and expense, maintain the
Landlord Landscaping and pay to Tenant the cost of any utilities used in
connection with Landlord's Landscaping; provided, however, that in the event
that Landlord fails or refuses to maintain its landscaping or pay for utilities
used in connection with Landlord's Landscaping, Tenant may cause such
obligations to be performed or discharged and upon receipt of written demand
from Tenant, Landlord shall reimburse Tenant for all costs in relation thereto.
Any amounts advanced by Tenant and not reimbursed by Landlord as provided herein
shall accrue interest at the rate of twelve percent (12%) per annum until paid.
Landlord shall install, at Landlord's sole cost and expense, any necessary
separate meters for any utilities used in connection with the Landlord
Landscaping. Landlord shall coordinate its installation and maintenance program
with Tenant; provided, however, that in no event and at no time may any Landlord
Landscaping or Landlord's installation and maintenance program therefore
interfere with or delay Tenant's construction schedule for the Facility or the
operation of or access to the Facility.

        (c) Alterations. Tenant shall have the right to make additions,
improvements and alterations to the Facility and Distribution System
(collectively, "Alterations") from time to time during the Lease Term; provided,
however, that prior to altering the exterior of the Facility or the footprint of
the Facility, Tenant shall obtain the Landlord's prior written consent, which
consent shall not be unreasonably withheld.

        (d) Mutual Cooperation. Landlord and Tenant, both acting reasonably,
agree to cooperate with each other so that the Landlord's Work and Tenant's Work
can be completed in a timely manner to permit completion of the Facility and
commencement by Tenant of exporting of chilled water service there from by not
later than June 26, 2000. Tenant shall prosecute construction of any
improvements on the Premises with due diligence, subject, however, to
unavoidable delays and/or Force Majeure Events.

        (e) All Improvements, Construction and Alterations. All improvements,
construction and alteration shall be constructed in a good and workmanlike
manner in accordance with all applicable rules, regulations and codes. Tenant
shall provide Landlord with as-built construction documents for the Facility for
safety purpose in the event of an emergency. Other than as necessary for safety
purposes, Landlord agrees not to disclose such documents without the prior
written consent of Tenant.

                 ARTICLE 6 - INSURANCE AND WAIVER OF SUBROGATION

        Section 6.1 Insurance. At all times from and after the date hereof,
Tenant and Landlord shall each, at its sole expense, purchase and maintain in
full force and effect, the insurance coverage set forth in Exhibit E hereto.

                                       9
<PAGE>   58

        Section 6.2 Additional Requirements. All insurance required to be
purchased by Tenant or Landlord pursuant to this Article 6 shall be placed with
reputable companies licensed to do business in the State of Nevada and shall
provide for deductibles reasonably acceptable to Landlord or Tenant, as
applicable. Prior to the Commencement Date, each party shall deliver to the
other certificates of insurance evidencing the insurance required hereby. All
such insurance will require not less than thirty (30) days prior written notice
to both parties in the event of modification or cancellation of coverage.

        Section 6.3 Waiver of Subrogation Rights; Default. Each party hereby
releases and waives for itself and, to the extent legally possible for it to do
so, without invalidating its insurance coverage, on behalf of its insurer, the
other party hereto and its respective officers, directors, agents, members,
partners, servants, and employees from liability for any loss or damage to any
or all property located on the Other Lands or the Premises which loss or damage
is of the type and within the limits covered by the "all-risk" property damage
insurance and other property/casualty insurance which the parties have agreed to
obtain and maintain in effect pursuant to Section 6.1, irrespective of any
negligence on the part of the released party and its respective officers,
directors, agents, partners, members, servants, or employees, which may have
contributed to or cause such loss or damage. Each party covenants that it will,
if available, obtain for the benefit of the other party and its officers,
directors, agents, members, partners, servants, and employees, a waiver of any
right of subrogation which the insurer of such party may acquire against such
party by virtue of the payment of any such loss covered by property/casualty
insurance. In the event a party is by law, statute or governmental regulation
unable to obtain a waiver of the right of subrogation for the benefit of the
other party (and its respective, officers, directors, agents, members, partners,
servants, and employees) or its insurance carriers will not give such a waiver
or its property/casualty insurance will be invalidated or terminated by the
waiver and release set forth in the first sentence of this Section 6.3, then,
during any period of time when such waiver is unobtainable, said party shall not
have been deemed to have released any subrogated claim of its insurance carrier
against such other party (or its respective officers, directors, agents,
members, partners, servants, or employees), and during the same period of time,
such other party shall not have been deemed to have released the party which has
been unable to obtain such waiver (or such party's respective officers,
directors, agents, members, partners, servants, or employees) from any claims it
or its insurance carrier may assert which otherwise would have been released
pursuant to this Section 6.3.

        Section 6.4 Failure of Tenant to Insure. If Tenant at any time fails to
provide the insurance coverage required by Section 6.1, Landlord will be
entitled, but not obligated, to purchase such coverage, after written notice of
Landlord's intent, and to collect the cost of such coverage from Tenant as
additional rent. Any amounts advanced by Landlord and not reimbursed by Tenant
as provided herein shall accrue interest at the rate of twelve percent (12%) per
annum until paid.

        Section 6.5 No Consequential Damages. Notwithstanding anything to the
contrary in this Lease, in no event shall Landlord or Tenant be liable to the
other for any lost business, loss of profits or other special and/or
consequential damages, whether direct or indirect, in respect of which each
hereby excuses the other and waives any and all such claims against the other,
provided that

                                       10
<PAGE>   59

the foregoing is not intended to be a waiver of any rights or obligations of
Tenant or Landlord under any Chilled Water Service Agreement or other agreement
between Fitzgeralds Las Vegas, Inc. and Tenant.

         ARTICLE 7 - DAMAGE OR DESTRUCTION OF FACILITY AND CONDEMNATION

        Section 7.1 Damage or Destruction. If any building or improvement at any
time on the Premises or Landlord Signage shall be damaged or destroyed by any
cause whatsoever (other than the negligence or willful misconduct of the
Landlord), during the first seventeen (17) years of this Lease, Tenant shall,
with reasonable promptness repair and replace the same at its own expense, to at
least the condition existing immediately prior to such damage or destruction,
and shall do so, even though proceeds of any insurance policies covering the
loss shall be insufficient to reimburse Tenant therefore; provided, however that
if such proceeds of insurance are more than sufficient to pay the cost of any
such rebuilding, Tenant shall be entitled to receive any surplus. Except for
damage or destruction caused by the negligence or willful misconduct of
Landlord, Tenant shall not be entitled to any abatement of Rent during any
period of reconstruction nor shall Tenant's obligations under this Lease be
terminated, notwithstanding any damage or destruction to said building or
improvements.

        If during the last three (3) Lease Years of the Initial Term or any
Renewal Term the Facility is damaged to the extent of fifty percent (50%) or
more of the full restoration cost (exclusive of the land and foundations), then
this Lease may be terminated at the election of either Landlord or Tenant,
provided that notice of such election shall be delivered by the electing party
to the other within thirty (30) days after the occurrence of such damage or
destruction. Upon the exercise of such option to terminate by either party
hereto, this Lease shall be deemed of no further force or effect, the parties
shall be released from all further liabilities thereafter arising under this
Lease, except as to indemnity, and any pre-existing unperformed obligations, and
all Rent or other charges paid by Tenant for periods after the date of
destruction shall be promptly refunded. Notwithstanding the foregoing, however,
if at the time of such damage or destruction Tenant has the right to extend the
Term as provided in Section 3.3 hereof, then Tenant may elect to exercise such
right within twenty (20) days after receiving notice of Landlord's election to
terminate pursuant to this Section 7.1, and in such case Landlord's notice of
termination shall be void and Tenant shall diligently proceed to repair the
Facility. Notwithstanding the termination of this Lease as provided in this
paragraph, Tenant's obligation for unpaid Rent, Additional Rent or any other
sums due under this Lease through the date of termination, restoration of the
Premises and Landlord and Tenant's indemnification obligations shall survive
such termination as provided in the Lease. Notwithstanding that Tenant's future
obligation to pay Rent under the Lease may be terminated pursuant to this
paragraph, to the extent that Tenant is entitled to any insurance proceeds
related to the destruction of the Facility after the discharge and full payment
of all of Tenant's creditors who have a security interest in the Facility,
Distribution System, Chilled Water Agreements or any equipment within the
Facility, Landlord shall be entitled to receive from the remaining insurance
proceeds an amount equal to the Base Rent that would otherwise have been due
under the Lease, exclusive of any adjustments, for the remainder of the Lease
term then in effect.

        Section 7.2 Eminent Domain. If the whole of the Premises (or such part
of the Premises that the balance of the Premises is no longer suitable for
Tenant's permitted use) shall be taken by any public authority under the power
of condemnation or eminent domain, the term of this Lease shall cease as of the
date possession shall be taken by such public authority, except as to indemnity
and any pre-existing unperformed obligations, and Tenant shall pay Rent,
additional rent and any other sums due under this Lease up to that date with an
appropriate refund by Landlord of such Rent as may have been paid in advance for
any period subsequent to the date possession is taken. If less than all of the
Premises shall be so taken (and the balance of the Premises is suitable for
Tenant's permitted use), the term of this Lease shall continue, but the Premises
shall be redefined to properly identify and delete that portion of the Premises
that has been taken and Tenant shall pay Rent and any other sums due under this
Lease up to the date of possession by a public authority with appropriate refund
by Landlord of such prorated Rent as may have been paid in advance for any
period subsequent to the date possession is taken. Thereafter the Base Rent
shall be proportionately adjusted and Tenant shall promptly restore the
remaining improvements on the Premises, exclusive of any Landlord Signage
effected by such taking. Landlord and Tenant shall each be entitled to
participate in the negotiations and settlement of any amounts or other
compensation in connection with the condemnation or other taking of the Premises
or any part thereof.

                             ARTICLE 8 - ASSIGNMENT

        Section 8.1 Assignment. Except for a "Permitted Transfer" (as such term
is herein defined) which may be made at any time without Landlord's consent, but
only after prior written notice to Landlord, Tenant shall not, either prior or
subsequent to the commencement of the Initial Term or a Renewal Term, assign
this Lease or any interest under this Lease without Landlord's prior written
consent, which consent shall not be unreasonably withheld or delayed. For
purposes of this Article 8, the term "Permitted Transfer" shall mean: 1) any
transfer or assignment of Tenant's interest in this Lease made in connection
with a transfer of Tenant's interest in the Facility in a transaction permitted
by the terms of any Chilled Water Service Agreement between Tenant and Landlord,
and their respective successors and assigns; 2) a transfer of Tenant's interest
in the Lease and Facility to another entity that is directly or indirectly a
wholly-owned subsidiary of Sierra Pacific Resources. In any event, no such
assignment shall be valid unless there shall be delivered to Landlord in due
form for recording, within ten (10) days after the date of the assignment (a) a
duplicate original of the instrument of assignment, and (b) an instrument of
assumption by the transferee of all of the Tenant's obligations under this Lease
and under the Landlord's Chilled Water Agreement; and (c) Tenant or assignee
shall within sixty (60) days prior to effective date of assignment provide
evidence that the prospective assignee is a reputable party whose financial net
worth, credit and financial responsibility is considering the responsibilities
involved, reasonably satisfactory to Landlord.

        Landlord acknowledges and agrees that the transferee under any
assignment or transfer to which Landlord has consented as aforesaid, as well as
the transferee or assignee under any Permitted Transfer, shall be deemed to be
the "Tenant" for purposes of this Lease and shall be

                                       12
<PAGE>   61
afforded all of the rights, benefits and obligations of Tenant hereunder.

        Upon the effective date of any assignment or transfer of this Lease
conforming to the terms hereof, but not otherwise, the assignor shall have no
further liability under this Lease to Landlord except as to matters of liability
which shall have accrued and are unsatisfied as of such date, it being intended
that the covenants and obligations contained in this Lease on the part of Tenant
shall be binding upon Tenant and its successors and assigns only during and in
respect of their respective successive periods of tenancy, excepting any
covenants relating to indemnification for Hazardous Materials on, in or under
the Premises. Without limiting any of the foregoing, but in addition thereto,
any assignment in contravention of the terms hereof is void, but this shall not
impair any remedy of Landlord because of Tenant having engaged in an act
prohibited by the terms hereof.

        Section 8.2 Subletting by Tenant. Tenant may sublet all but not less
than all of said Premises provided that: 1) the potential subtenant assumes all
of Tenant's obligations under this Lease and any Chilled Water Agreement between
Tenant and Landlord; and 2) Tenant delivers to Landlord an executed counterpart
of such sublease which shall be expressly conditioned upon and subject to
Landlord's prior written consent and the terms hereof, together with full and
complete current financial statements of the potential sublessee, not less than
sixty (60) days prior to the effective date thereof. Landlord shall not
unreasonably withhold its consent to a proposed sublease provided the
prospective sublessee is a reputable party whose financial net worth, credit and
financial responsibility is, considering the responsibilities involved,
reasonably satisfactory to Landlord, and providing the sublessee uses the
Premises and Facility for the sole purpose of operating a Chilled Water
Facility. Any sublease in violation hereof shall be void, but without thereby
impairing any remedy of Landlord because of Tenant having engaged in an act
prohibited by the terms hereof. Additionally, Tenant will furnish to Landlord
for Landlord's approval, the floor plan for all of the space proposed to be
sublet by Tenant. And, the sublease shall contain a provision substantially to
the effect that if there be any termination of the within Lease then the
subtenant, at the request of Landlord, will attorn to Landlord, and the sublease
shall continue in effect with Landlord.

        Landlord agrees to enter into Nondisturbance and Attornment Agreements
with subtenants of Tenant if the sublease of such subtenant shall have been
first approved in writing by Landlord. Without limiting that which would
constitute reasonable grounds for Landlord's withholding of approval, it is
agreed that it shall not be deemed unreasonable for Landlord to refuse to give
such consent to any such sublease if the sublessee cannot demonstrate that it
has the financial ability to perform under the terms of this Lease. In no
circumstance shall Landlord be required to give its approval if such sublease
(i) calls for the granting of a concession in rent, or (ii) would impose upon
the Landlord any obligation to make alterations to the Premises demised under
the sublease or to pay the subtenant for alterations made by it.

        Section 8.3 Consent Not a Release. Neither a Permitted Transfer nor the
consent by Landlord to any assignment or subletting shall be deemed to be a
consent to or relieve Tenant from obtaining Landlord's consent to any subsequent
assignment or subletting requiring consent under

                                       13
<PAGE>   62
Section 8.1 above.

        Section 8.4 Transfer by Landlord - Release From Liability. In the event
Landlord shall sell or transfer the Premises or any part thereof, and as a part
of such transaction shall assign its interest as Landlord in and to this Lease,
and Landlord shall provide an instrument of assumption by the transferee of all
the obligations of Landlord under this Lease. Then from and after the effective
date of such sale, assignment, or transfer, Landlord shall have no further
liability under this Lease to Tenant except as to matters of liability which
shall have accrued and are unsatisfied as of such date, it being intended that
the covenants and obligations contained in this Lease on the part of Landlord
shall be binding upon Landlord and its successors and assigns only during and in
respect of their respective successive periods of ownership of the fee,
excepting any covenants relating to indemnification for Hazardous Materials on,
in or under the Premises as set forth in this Lease, and the granting of those
certain easements in, under and over the Landlord Parcel as described in this
Lease. Tenant shall, immediately upon written request from any such assignee,
execute and deliver to such assignee an instrument in proper form by which
Tenant attorns to said assignee.

                       ARTICLE 9 - LIENS AND ENCUMBRANCES

        Section 9.1 Encumbering Landlord's Title. Tenant shall make all payments
and take all actions at its own cost and expense as may be necessary to ensure
that no lien, charge, or order for payment of money is registered against
Landlord's interest in and to the Premises that results from any work, services
or materials supplied to Tenant or the Facility or any act or omission of Tenant
and that is not discharged or vacated (or with respect to which payment has not
been secured by the placement of a bond in an amount, form and content
reasonably acceptable to Landlord) within thirty (30) Business Days after Tenant
receives notice of such registration. Tenant shall indemnify, defend and save
harmless Landlord against any and all costs, liabilities, suits, penalties,
claims and demands, including reasonable attorney's fees, arising there from.
Any claim to, or lien upon, the Premises arising from the acts or omissions of
Tenant shall accrue only against the leasehold estate of Tenant and the Tenant's
interest in the Facility. If Tenant fails to cause such lien, charge or order to
be discharged of record or bonded within ninety (90) Business Days after Tenant
receives notice of such registration, then Landlord shall have the right to
cause the same to be discharged. All amounts paid by Landlord to cause any such
lien, charge or order to be discharged shall constitute additional Rent payable
by Tenant to Landlord, or, at Landlord's option, may be recovered from Tenant in
an appropriate proceeding.

        Section 9.2 Collateral Assignment and Liens. Landlord agrees that Tenant
shall have the right to grant to a lender a security interest in Tenant's
interest in this Lease for collateral purposes and to grant to such lender
security interests in and liens on the personal property, fixtures, machinery
and equipment of Tenant located on the Premises. Tenant covenants and agrees to
promptly provide to Landlord a copy of any notice of default received by Tenant
from Tenant's lender.

'
                              ARTICLE 10 - UTILITIES

        Section 10.1 Utilities; Services. Tenant shall purchase the water, gas
and sewage services necessary for the operation of the Facility directly from
the utility, authority or municipality providing such service, and shall pay for
such services when such payments are due. Tenant covenants to pay all such
charges for these utility services and any others required in the operation of
its business on or before their due date.

                             ARTICLE 11 - INDEMNITY

        Section 11.1 General Indemnity. Subject to Section 11.2 below, each
party hereto shall protect, indemnify and save the other party and its agents
and employees harmless from and against all liabilities, obligations, claims,
damages (other than lost business, lost profits and other special and/or
consequential damages, whether direct or indirect, all claims for which are
hereby irrevocably waived), penalties, causes of action, costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) imposed
upon or asserted against such other party by reason of any accident, physical
injury to or death of persons or physical loss of or physical damage to property
arising:

                (a) from the conduct of such party's business;

                (b) from any breach or default on the part of the indemnifying
        party in the performance of any covenant or agreement on the part of
        such party to be performed pursuant to the terms of this Lease;

                (c) from the indemnifying party's violation of any Federal,
        state or local law, regulation or action governing environmental or
        workman or Facility operations safety statutes applicable to the
        Facility or work being performed; or

                (d) due to any other legally actionable act or omission of the
        indemnifying party or its agents, contractors or employees.

In case any action, suit or proceeding is brought against a party hereto by
reason of any such occurrence, at the indemnified party's option, the
indemnifying party shall, at the indemnifying party's sole cost and expense, by
counsel selected by the indemnifying party (which counsel must be reasonably
satisfactory to the indemnified party), defend such action, suit or proceeding,
or cause the same to be defended.

        Section 11.2 Limitation on Indemnity. The aforesaid indemnification
shall not be applicable to any claim, demand, penalty, cause of action, fine,
liability, settlement, damage, cost or other expense of any type whatsoever
occasioned, arising and caused solely and directly as the result of the
negligence or willful misconduct of a party claiming a right to be indemnified
or its agents or employees.

                                       15
<PAGE>   64

        Section 11.3 Effect of Waiver. The indemnities of either party contained
in this Lease shall not apply or pertain to liabilities, obligations, claims,
damages, penalties, causes of action, costs or expenses to the extent such party
has waived claims in respect thereto pursuant to Section 6.3 above.

        Section 11.4 Survival of Obligation. The duty to indemnify under this
Article 11 will continue in full force and effect notwithstanding the expiration
or termination of this Lease, with respect to any loss, liability, damage or
other expense based on factors and conditions which occurred prior to such
termination.

                               ARTICLE 12 - TITLE

        Section 12.1 Title; Subordination. Landlord may mortgage or otherwise
encumber the premises; however, Landlord agrees to promptly notify Tenant in
writing of any mortgage, trust deed, or ground lease encumbering the Premises,
other than the mortgages in effect as of the date hereof (copies of which
Landlord has provided to Tenant). If at any time the Premises shall become
subject to any mortgage, trust deed or ground lease, other than the mortgages in
effect on the date hereof, Landlord shall deliver to Tenant a recordable
non-disturbance agreement (pursuant to which, among other things, the Lease, and
Tenant's right of possession of the Premises on the terms and conditions set
forth in the Lease, would be honored by any lender, ground lessor or person or
entity claiming by, through or under such lender or ground lessor, in the event
a foreclosure or deed-in-lieu of foreclosure occurred or a ground lease was
terminated and no Tenant Default then existed) satisfactory in form and
substance to Tenant acting in a commercially reasonable manner (herein called a
"Non-Disturbance Agreement") signed by such lender or ground lessor, as the case
may be. In the event Landlord should request an extension of time to procure a
non-disturbance agreement, said request shall be granted provided Landlord
demonstrates it has made a request for the non-disturbance agreement within the
initial 30 day period.

        With respect to the existing mortgages identified on Annex B Section
(e), Landlord shall obtain Non-Disturbance Agreements, in a form reasonably
acceptable to Tenant, from the mortgagees thereunder prior to the Commencement
Date, which obligation is a condition precedent as set forth on Annex D.

        Without limiting the foregoing, if the mortgagee or trustee in any first
mortgage or first trust deed hereafter made desires this Lease to be subject and
subordinate to its mortgage or trust deed, then all or a portion of the rights
and interests of Tenant under this Lease (other than rights in respect of any
Taking) shall be subject and subordinate to such mortgage or trust deed and to
any and all advances to be made thereunder, and to the interest thereon, and all
renewals, replacements and extensions thereof, if and only if such mortgagee or
trust deed holder or such ground lessor, as the case may be, has delivers to
Tenant a Non-Disturbance Agreement signed by such lender or ground lessor, as
the case may be. Any mortgagee or trustee in any mortgage or trust deed
hereafter made may elect that, instead of making this Lease subject and
subordinate to its mortgage or trust deed, the rights and interest of Tenant
under this Lease shall have priority over the lien of its mortgage or trust
deed. Tenant agrees that in the event that any trustee or mortgagee or ground

                                       16
<PAGE>   65

lessor elects to make this Lease subordinate to its mortgage, trust deed or
ground lease, and Tenant receives from such lender or ground lessor a signed
Non-Disturbance Agreement in a form reasonably acceptable to Tenant, Tenant
shall, upon the request thereof, attorn to any such trustee or mortgagee who
becomes owner of the Premises through foreclosure or deed in lieu of foreclosure
or to any other purchaser of the Premises at a foreclosure sale or to such
ground lessor, as the case may be.

                      ARTICLE 13 - SURRENDER AND HOLDOVER.

        Section 13.1 Surrender and Removal of Improvements. No later than the
180th day following the date on which this Lease expires or is terminated in
accordance with the terms hereof, but subject to extension upon the occurrence
of a Force Majeure Event or delays caused by Landlord, Tenant shall surrender
the Premises to Landlord, free and clear of any liens or encumbrances arising
out of the use and operation of the Facility by Tenant. Additionally, Tenant
shall have removed from the Premises any and all machinery, equipment and
personal property and other improvements at Tenant's expense and shall have
restored the Premises to a level, graded condition acceptable to Landlord and
otherwise as reasonably practicable restore the Premises to its original
condition. Tenant's interest in any improvements remaining on the Premises after
the 180th day following expiration or earlier termination of this Lease shall be
vacated and surrendered by Tenant to Landlord, without the payment of any
consideration, unless otherwise agreed to, in writing, by the parties, and shall
automatically become the property of Landlord. Landlord may but shall not be
obligated to remove and/or store any of Tenant's property or improvements left
on the Premises after expiration of the 180 day period. Should Landlord elect to
remove and/or store Tenant's remaining property, upon written demand by
Landlord, Tenant shall pay to Landlord all reasonable costs incurred by Landlord
in connection with the storage or removal of any machinery, equipment and
personal property and other improvements which Tenant has not removed. Any sums
not paid when due shall accrue interest at the rate of twelve percent (12%) per
annum until paid.

        Upon the expiration of the Lease Term or sooner termination of this
Lease, Tenant shall execute, acknowledge and deliver to Landlord a proper
instrument in recordable form, releasing and quitclaiming to Landlord all right,
title and interest of Tenant in and to the Premises, other lands and easements
granted herein by Landlord to Tenant.

        Section 13.2 Holding Over. Except for the 180 day period referred to in
Section 13.1 above or such shorter period as Tenant requires in order to remove
the Facility under Section 13.1 (and it is agreed that Tenant shall pay Landlord
Rent and Impositions at the rate(s) in effect during such 180 days or shorter
holdover period, payable monthly in advance), Tenant shall have no right to
occupy the Premises or any portion thereof after the expiration of the Term or
after termination of this Lease or of Tenant's right to possession. In the event
Tenant holds over, Landlord may exercise any and all remedies available to it at
law or in equity to recover possession of the Premises and for any damages
resulting from such holdover.

                              ARTICLE 14 - DEFAULTS

        Section 14.1 Tenant Default. Tenant agrees that any one or more of the
following events shall be considered a "Tenant Default" as said term is used
herein:

                (a) Tenant shall fail to pay any Rent or other charge owing by
        Tenant pursuant to the terms of this Lease, and such failure shall
        continue for fifteen (15) days after notice thereof in writing to
        Tenant:

                (b) Tenant shall fail to keep, observe or perform any of the
        other covenants or agreements herein contained to be kept, observed and
        performed by Tenant, and such failure shall continue for thirty (30)
        days (or such shorter period as is specifically referred to in this
        Lease for any particular breach) after notice thereof in writing to
        Tenant; provided, however, in the event that such failure cannot
        reasonably be cured within the aforesaid thirty (30) day period (or
        shorter period, if applicable), and Tenant shall within said period
        commence to cure said default and diligently thereafter prosecutes to
        correction said failure, the period for completion shall be extended for
        so long as is reasonably required to cure said default; or

                (c) The estate or interest of Tenant in the Premises is levied
        upon or attached in any proceeding and such process is not stayed,
        vacated or discharged within ninety (90) days after such levy or
        attachment.

                (d) Abandonment or surrender of the Premises or of the leasehold
        estate.

                (e) The appointment of a receiver to take possession of Tenant's
        interest in the Premises, Tenant's improvements on the Premises,
        Tenant's interest in the leasehold estate, or of Tenant's operations on
        the Premises for any reason, including but not limited to assignment for
        benefit of creditors or voluntary or involuntary bankruptcy proceedings,
        but not including receivership (i) pursuant to any mortgage permitted by
        provisions of this Lease relating to purchase or construction of
        improvements, or (ii) instituted by Landlord, the event of default being
        not the appointment of a receiver at Landlord's instance but the event
        justifying the receivership, if any.

                (f) An assignment by Tenant for the benefit of creditors or the
        filing of a voluntary or involuntary petition by or against Tenant under
        any law for the purpose of adjudicating Tenant bankrupt; or for
        extending time for payment, adjustment or satisfaction of Tenant's
        liability; or for reorganization, dissolution, or arrangement on account
        of or to prevent bankruptcy or insolvency; unless the assignment or
        proceeding, and all consequent orders, adjudications, custodies and
        supervisions are dismissed, vacated or otherwise permanently stayed or
        terminated within thirty (30) days after the assignment, filing, or
        other initial event.

                Section 14.2 Landlord Remedies. In the event of any such Tenant
        Default,

                                       18
<PAGE>   67

Landlord may, at any time thereafter, with or without notice or demand, and
without limiting Landlord in the exercise of any right or remedy which Landlord
may have by reason of such default or breach, do any number or all of the
following:

        (a) Terminate Tenant's right to possession of the Leased Premises, in
which case this Lease shall terminate and Tenant shall immediately surrender
possession of the Leased Premises to Landlord. In such event, Landlord shall be
entitled to immediately recover from Tenant the following: all damages incurred
by Landlord by reason of Tenant's default, including, but not limited to, the
cost of recovering possession of the Leased Premises; expenses of reletting,
reasonable attorneys' fees and any real estate commission actually paid; and the
worth at the time of the amount by which the unpaid rent for the balance of the
term after the breach exceeds the amount of such rental loss for the same period
that Tenant proves could be reasonably avoided. All sums due Landlord pursuant
to this paragraph 14.2 (a) shall bear interest at the annual rate of twelve
percent (12%) from the date the same becomes due and payable hereunder, and in
the event such sum is an expenditure of money by Landlord, then from the date
such expenditure is made by Landlord. Landlord shall have an affirmative duty to
mitigate.

        (b) Terminate Tenant's possession, but not terminate this Lease, in
which event Landlord may lease the Leased Premises for the account of Tenant,
and Tenant shall pay any deficiency in rent, and all other charges incurred by
Landlord attributable to the breach and reletting. Landlord shall not be deemed
to be unreasonable in its mitigation efforts if it refuses to let the Leased
Premises to a person or entity which does not meet the criteria set forth in
paragraphs 5.1 and 14.2, above.

        (c) Maintain Tenant's right to possession in which case this Lease shall
continue in effect, whether or not Tenant shall have abandoned the Leased
Premises. In such event, Landlord shall be entitled to enforce all of Landlord's
rights and remedies under this Lease, including the right to recover the rent
and all other sums as they become due hereunder.

        (d) Terminate this Lease.

        Subject to the foregoing, Landlord shall have such rights and remedies
for Tenant defaults as provided elsewhere in this Lease and at law and in
equity, and all remedies shall be cumulative such that Landlord's exercise or
failure to exercise any remedy shall not limit or prevent Landlord from
exercising any other remedy available to Landlord. Notwithstanding the
foregoing, Tenant may offset against any damages owed by Tenant to Landlord any
amounts due or damages awarded or incurred pursuant to that certain Chilled
Water Services Agreement between Landlord and Tenant, provided, however, that
Tenant shall not offset any payment of Base Rent unless amounts payable under
the Chilled Water Services Agreement are at least thirty (30) days past due.

        Section 14.3 Performance by Tenant's Tender. Tenant may make a mortgage
or mortgages of its interest in this Lease and Tenant may grant security
interests in the Facility, Distribution System and equipment and improvements on
the Premises. If Tenant shall have made any such mortgage or security interest,
(the holder of such mortgage and/or security

                                       19
<PAGE>   68

interest being herein referred to as "Leasehold Mortgagee" and such mortgage
being herein sometimes referred to as "Leasehold Mortgage") and if the Leasehold
Mortgagee(s) shall have given to Landlord a notice ("Leasehold Mortgagee's
Notice") specifying the name and address of the Leasehold Mortgagee, Landlord
shall give to the Leasehold Mortgagee a copy of each notice of a default by
Tenant at the same time as and whenever any such notice of a default shall
thereafter be given by Landlord to Tenant, addressed to such Leasehold Mortgagee
at the address last furnished to the Landlord. Failure to give simultaneous
notice of such Leasehold Mortgagee shall not impair any notice properly given to
Tenant and shall not enlarge Tenant's cure period. Such Leasehold Mortgagee
shall thereupon have an additional period of thirty (30) days, after service of
such notice upon it for remedying the default or causing the same to be
remedied, than is given Tenant after service of such notice upon Tenant. Such
Leasehold Mortgagee, in case Tenant shall be in default, shall, within the
additional period, and otherwise as herein provided, have the right to remedy
such default or cause the same to be remedied. No default by Tenant shall be
deemed to exist, so long as the Leasehold Mortgagee shall have notified Landlord
within the period of time allowed for Tenant to cure that the Leasehold
Mortgagee intends to cure on behalf of the Tenant within the additional 30 day
cure period. From and after receiving the Leasehold Mortgagee's Notice, Landlord
and Tenant will not cancel, surrender, modify, or amend this Lease in any
respect without the prior written consent of the Leasehold Mortgagee.

        If a Leasehold Mortgagee shall acquire Tenant's interest in the Lease as
a result of a sale under such Leasehold Mortgage pursuant to a power of sale
contained herein, pursuant to a judgment or foreclosure or through any transfer
in lieu of foreclosure, such Leasehold Mortgagee shall have the privilege of
transferring its interest in this Lease to a nominee or a wholly owned
subsidiary corporation with the prior consent of Landlord (which consent shall
not be unreasonably withheld) and provided, that there shall be delivered to
Landlord in due form for recording, within ten days after the date of such
transfer (a) a duplicate original or the instrument of assignment, and (b) an
instrument of assumption by the transferee of all of the Tenant's obligations
under this Lease, and said Leasehold Mortgagee shall be relieved of any further
liability under this Lease from and after the effective date of such transfer,
except as to matters of liability which shall have accrued and are unsatisfied
as of such date. Any purchaser at a foreclosure sale, other than a Leasehold
Mortgagee, must assume this Lease and it shall have no right in respect to the
Premises unless it so assumes and delivers a duplicate original of the
assumption agreement (to be executed in form for recording) within ten (10) days
after such purchaser acquired title to the Tenant's interest in this Lease.
Under no circumstances may the purchaser or new tenant be in the lodging or
gaming industry.

        Section 14.4 Landlord Default; Tenant Remedies. In the event Landlord
shall fail to keep, observe or perform any of its covenants or agreements
contained in this Lease and such failure shall continue for thirty (30) days

building, the chilled water plant including the plate and frame exchangers and
pumps will be located. The roof of the building will house the cooling towers.

The cooling plant is made up of electric driven water cooled chillers initially
totaling 3,600 nominal-tons, servicing approximately 2,200 tons connected
customer loads, primary and secondary pumps, VFDs, and a plate and frame Heat
exchanger. The primary piping headers have been sized for 5,000 nominal-tons
with future connections for 2 additional chillers.

The primary purpose of this building is to serve chilled water for cooling to
Downtown Las Vegas properties including gaming, commercial and governmental
customers.
