                                ENERGY SERVICE

      2.1   SERVICES; EXCLUSIVITY; RIGHT OF FIRST REFUSAL; PERFORMANCE; 
CUSTOMER AGREEMENTS.

            (a)   PROJECT SCOPE; CUSTOMER ENERGY REQUIREMENTS.  The Northwind 
Facilities will be engineered, designed and constructed under the terms of 
the Development Agreement and in accordance with the design and equipment 
parameters set forth in Exhibit A hereto (such Exhibit, as it may be amended, 
restated, modified or supplemented and in effect from time to time, is 
referred to as the "Project Scope"), to generate and provide to the Complex:  
(a) chilled water ("Chilled Water Services"), (b) hot water ("Hot Water 
Services"), and (c) primary and secondary AC electricity (up to and including 
the initial transformation) generated both by the Northwind Facilities and 
third party sources of electricity 



("Electricity Services", and together with Chilled Water Services and Hot 
Water Services, the "Services"), in capacities which are set forth in Exhibit 
A.  The characteristics and capacities of the Northwind Facilities have been 
agreed upon by the Parties pursuant to the statement of projected energy 
requirements for the Complex under the heading "Contracted Demand" set forth 
in Exhibit B hereto.  (The definitive specifications of the Plant Energy 
Requirements are set forth in Exhibit B.1 and the Customer Energy 
Requirements are set forth in Exhibit B.2.  Exhibit B.1, as it may be 
amended, restated, modified or supplemented and in effect from time to time, 
is referred to as the "Energy Requirements.")

            (b)   SERVICES.  Subject to the provisions of the Development 
Agreement, which govern the Supplier's obligation to engineer, design and 
construct the Northwind Facilities, the Supplier agrees that it will provide 
Initial Services up to the Initial Energy Requirements to the Customer on the 
Initial Services Date and Services to the Customer on the Substantial 
Completion Date up to the Energy Requirements.

            With respect to Electricity Services, the Northwind Facilities 
shall be capable of generating 4.9 megawatts.  The Supplier shall have the 
sole responsibility for procuring from third party electricity sources, and 
providing to the Customer up to the Specified Demand Amount in effect from 
time to time, the Electricity Services whether or not generated by the 
Northwind Facilities.

            (c)   EXCLUSIVITY; RIGHT OF FIRST REFUSAL.  The Supplier agrees 
that, so long as the Customer is not in default hereunder and subject to the 
provisions of the following paragraphs of this Section 2.1(c), the Customer 
shall have first call on that portion of the Services produced and procured 
by the Northwind Facilities necessary to serve the Customer Energy 
Requirements set forth in Exhibit B.1.  The Customer agrees that, for the 
term of this Agreement and thereafter so long as this Agreement remains in 
effect, it shall purchase all of its requirements for Services from the 
Supplier, except to the extent that, (i) the Customer's requirements for 
Services exceed its allocated portion of Services as set forth in Exhibit B.1 
and the Supplier does not agree to supply such excess in accordance with this 
Section 2.1, or (ii) the Supplier does not supply such Services for any 
reason.

            If the Northwind Facilities are being operated to meet the Energy 
Requirements and the Customer determines that its requirements for one or 
more Services exceed those set forth in Exhibit B.1, and if the Northwind 
Facilities are then able to supply such additional requirements of Services 
(the "Additional Services") and the Supplier has not entered into commitments 
to sell such Services to 



anyone else other than the Complex Energy Service Agreements, which, while 
this Agreement is in effect, the Supplier shall not do without the prior 
written consent of the Customer, then the Customer shall have the obligation 
to purchase all the Additional Services from the Supplier except as otherwise 
permitted by this Section 2.1 and Section 6.1(c) and Section 6.3, and the 
Supplier shall be obligated to supply the Additional Services.

            In the event that the Customer shall determine that its Services 
requirements exceed those set forth in Exhibit B.1 hereto and the provision 
of such Services would not require the Plant to exceed the capacities set 
forth on Exhibit A hereto and the Supplier has not entered into commitments 
to sell such Services to third parties, in accordance with the terms hereof, 
then the Supplier shall provide such Services to the Customer at the existing 
rates comprising the Consumption Charges applicable to such Services, and 
without any increase in the Capacity Charges payable hereunder.

            In the event that the Customer shall determine that its Services 
requirements exceeds those set forth in Exhibit B.1 hereto and such Services 
requirements would cause the  Plant to exceed the capacities set forth in 
Exhibit A hereto, then the Customer will negotiate in good faith with the 
Supplier to reach agreement as to the terms and conditions upon which the 
Supplier will provide Additional Services, in accordance with Section 
2.1(c)(i)-(v) of this Agreement.  Customer may simultaneously solicit bids 
from other sources of energy services.  Supplier shall have the right to 
match the terms and conditions of the lowest tender or proposal within the 
bid process set forth below.  The terms and conditions of the bid process 
shall be as follows:

                  (i)   the Customer shall prepare a statement (the 
"Additional Services Request") setting forth specifics of the amount and type 
of the Additional Services which the Customer desires to obtain, the period 
for which the Additional Services are to be obtained, the date (or dates) 
upon which such Services are to commence, any changes to the Customer's 
equipment which are contemplated or intended to be made in connection 
therewith and such other information as may be relevant, and shall provide a 
copy of the Additional Services Request to the Supplier and request the 
Supplier to consider providing the Additional Services in accordance with the 
Additional Services Request.  In the event that the Supplier shall desire 
additional information or specifications concerning the matter, the Supplier 
shall request such information or specifications in writing and the Customer 
shall thereafter provide such additional information or specifications to the 
Supplier as 




soon as reasonably possible following such request and the Additional 
Services Request shall be deemed modified or supplemented to include the same;

                  (ii)  if the Supplier determines that it will offer to 
provide the Additional Services requested, then the parties shall negotiate 
in good faith the terms upon which the Additional Services shall be provided, 
including the amount of additional Contract Capacity Charges payable as a 
result of changes to the Plant and increased operations expenses only and 
additional Consumption Charges which will be payable by the Customer in 
respect thereof and upon reaching agreement with respect thereto the parties 
shall thereupon take all actions which are necessary to implement and carry 
out such agreement, including negotiating and executing any relevant 
documents or agreements (or amendments to existing documents and agreements) 
including an appropriate amendment to the Project Scope and to the Contract 
Capacity Charge and the Consumption Charges;

                  (iii) in addition to the above paragraphs (i) and (ii), the 
Customer may simultaneously provide the Additional Services Request to any 
other Person or Persons and solicit offers to provide the Additional Services 
from such other Person or Persons and if any of such other Persons responds 
with an offer to provide the Additional Services and the Customer determines 
that it intends to accept such an offer, then the Customer shall give written 
notice thereof to the Supplier which notice shall include a summary of the 
terms and conditions of the offer which the Customer intends to accept (the 
"Offer").  In the event that the Supplier desires additional information or 
clarification concerning the Offer, the Supplier shall request the same in 
writing within four (4) days of the date upon which it receives the 
notification and the Customer shall thereafter provide such additional 
information or clarification to the Supplier as permitted under the terms of 
the Offer as soon as reasonably possible following such request and the Offer 
shall be deemed modified or supplemented to include the same;

                  (iv)  the Supplier shall have ten (10) days from the date 
upon which it receives the notification (or ten (10) days from the date upon 
which it receives any additional information or clarification requested) 
under clause (iii) above that the Customer intends to accept the Offer to 
determine if the Supplier is willing to provide the Additional Services on 
the terms of the Offer and, if it is so willing, to so indicate to the 
Customer by written notice thereof to the Customer (the "Notice of Exercise") 
given within such ten (10) day period stating that the Supplier will provide 
the Additional Services on the terms and conditions set forth in the Offer, 
whereupon the Supplier shall be deemed to have made an offer to the Customer 
to provide the Additional Services on the terms and conditions set forth in 



the Notice of Exercise and the Offer and the Customer shall be deemed to have 
accepted such offer by the Supplier. Notwithstanding anything to the contrary 
contained herein, if the Supplier is unwilling or unable to match the Offer, 
the Customer shall have the right to purchase the Additional Services from 
such other Person or Persons;

                  (v)   the Customer and the Supplier shall thereupon take 
all actions which are necessary to implement and carry out the arrangements 
and undertakings contemplated by the Notice of Exercise and the Offer, 
including negotiating and executing any relevant documents or agreements (or 
amendments to existing documents and agreements), including an appropriate 
amendment to the Project Scope and to the Contract Capacity Charge and the 
Consumption Charges.

            In the event that any Additional Services Request contemplates 
increasing services in two or more phases, then, unless the Supplier and the 
Customer shall then agree otherwise, each such phase shall be deemed to be 
subject to a distinct right of first refusal hereunder and the Customer shall 
be required to comply with the procedures set forth herein with respect to 
each such phase.

            (d)   PERFORMANCE.  At all times while this Agreement is in 
force, but subject to the terms hereof,  the Supplier will operate the 
Northwind Facilities to comply with the Project Scope and all applicable 
federal, state and local codes, laws, rules and regulations.  The Supplier's 
obligations will include, but not be limited to, (i) performing all 
day-to-day operations, routine testing, normal maintenance, service and 
repair of the Northwind Facilities; (ii) the estimating, scheduling, 
coordinating and monitoring the performance of any extraordinary service, 
maintenance, repair, improvement or modification to the Northwind Facilities; 
(iii) carrying out such performance tests of equipment as is required under 
this Agreement or otherwise reasonably requested by the Customer; (iv) 
coordinating maintenance and power deliveries with the Customer and (v) 
providing for the handling and disposal of chemicals and hazardous materials 
at and from the Site; and (vi) subject to Section 5.7, obtaining and 
maintaining all required licenses, permits, approvals and clearances to 
provide the Services and operate the Northwind Facilities.  The Supplier 
shall at all times maintain the appropriate operating personnel at the 
Northwind Facilities, twenty four (24) hours per day, seven (7) days per 
week. The Supplier agrees to coordinate matters with those parties designated 
by the Customer to be the Customer's representative with respect to this 
Agreement or portions thereof.



            The Customer shall have the right, upon at least twenty four (24) 
hours' advance notice, or no notice in the event of an emergency, to inspect 
the operation of the Northwind Facilities during normal business hours and to 
review the Supplier's maintenance and operating records to assure compliance 
with this Section 2.1(d).

      2.2   CHILLED WATER.

            (a)   Commencing on the Commencement Date, the Supplier agrees to 
supply at the Chilled Water Delivery Point and the Customer agrees to 
purchase the Customer's requirements of Chilled Water Service up to the 
capacity or capacities described in Exhibit B.2 under the heading "Contracted 
Demand". Chilled water the Supplier provides under this Agreement shall not 
be intermixed by the Customer with any other water or other substances 
without the prior written consent of the Supplier, which consent shall not be 
unreasonably withheld.

            (b)   The Supplier shall ensure that the chilled water is 
delivered to the Chilled Water Delivery Point at a design temperature of not 
more than 36 degrees Fahrenheit, measured at the Chilled Water Delivery Point.

            (c)   Provided that the Supplier is in compliance with Section 
2.2(b) above, the Customer will ensure that all chilled water supplied 
hereunder is returned to the Supplier at the Chilled Water Return Point at a 
temperature not less than 20 degrees Fahrenheit in excess of the temperature 
at which such chilled water was supplied and otherwise uncontaminated in any 
material respect and in the condition in which it was received.  In the event 
Customer fails to comply with this Section 2.2(c), the Supplier may elect, as 
its sole remedy (other than as set forth in Section 6.2(a) and Section 6.3(a) 
with respect to a Payment Default), to determine the actual cost(s) to the 
Supplier of such failure and invoice the Customer on the next monthly invoice 
under Section 2.7 for such amount(s) as additional Consumption Charges 
hereunder.  In such event, the Supplier shall notify the Customer of such 
action and such invoice(s) shall be accompanied by detailed calculations 
demonstrating the manner in which such additional Consumption Charges have 
been determined, and such additional Consumption Charges shall thereupon be 
payable in accordance with Section 2.8.

      2.3   HOT WATER.

            (a)   Commencing on the Commencement Date, the Supplier agrees to 
supply at the Hot Water Delivery Point and the Customer agrees to 



purchase the Customer's requirements of Hot Water Services up to the capacity 
or capacities described in Exhibit B under the heading "Customer Energy

is returned to the Supplier at the Hot Water Return Point at a temperature at 
least 35 degrees Fahrenheit less than the temperature at which it was 
delivered and otherwise uncontaminated in any material respect and in the 
condition in which it was received.  In the event Customer fails to comply 
with this Section 2.3(c), the Supplier may elect to determine the actual 
cost(s) to the Supplier of such failure and invoice the Customer on the next 
monthly invoice under Section 2.7 for such amount(s) as additional 
Consumption Charges hereunder.  In such event, the Supplier shall notify the 
Customer of such action and such invoice(s) shall be accompanied by detailed 
calculations demonstrating the manner in which such additional Consumption 
Charges have been determined, and such additional Consumption Charges shall 
thereupon be payable in accordance with Section 2.8.

      2.4   ELECTRICITY.  Commencing on the Commencement Date, the Supplier 
shall make available at the Electricity Delivery Points electricity to meet 
all of the Customer's primary and secondary AC electricity (up to and 
including the initial transformation -- i.e., immediately prior to the 
Customer Interconnection Equipment) needs for the Premises, up to the

      2.5   CHARGES.  In consideration of the Supplier's undertakings 
hereunder, the Customer shall pay to the Supplier, when and in the manner 
required by Section 2.8, the following charges, as the same may be adjusted 
from time to time pursuant to Section 2.6 and any other applicable provisions 
of this Agreement:

            (a)   CONTRACT CAPACITY CHARGE  - a monthly Contract Capacity 
Charge for Customer's share of the capital cost of the Plant determined in 
accordance with Exhibit C hereto, as the same may be amended, restated, 
modified or supplemented and in effect from time to time, for each month or 
portion thereof 



occurring after the Commencement Date, whether or not any Services are taken 
by the Customer during such month; and

            (b)   CONSUMPTION CHARGE  - a monthly Consumption Charge for 
Services actually taken by the Customer during each month or portion thereof 
occurring after the Substantial Completion Date, determined in accordance 
with Exhibit C hereto, as the same may be amended, restated, modified or 
supplemented and in effect from time to time, for each month or portion 
thereof occurring after the Substantial Completion Date.

The Contract Capacity Charge shall be paid by the Customer monthly in 
accordance with Section 2.8 so long as this Agreement remains in force and 
has not been terminated, whether or not the Customer actually takes or uses 
any Services and, except as provided for in Section 6.1(c), whether or not 
there shall exist a default by the Supplier in any of its obligations 
hereunder.

      2.6   ADJUSTMENTS.

            (a)   On each annual anniversary of the Commencement Date, the 
Contract Capacity Charge and the Consumption Charges for the Contract Year 
then beginning shall be adjusted as set forth in Section 2.6 (b) and in 
accordance with Exhibit C.

            (b)   The Supplier shall adjust the Contract Capacity Charge 
payable during the remaining term hereof then in effect and the Consumption 
Charges to reflect any changes in Supplier's costs of providing any Service 
that results directly from the adoption or modification of any applicable 
laws, rules or regulations of any governmental authority, or from any change 
in the interpretation by any court, tribunal or regulatory agency of any such 
applicable laws, rules or regulations or any other Force Majeure Event, after 
the date of this Agreement, and such adjustment shall become effective 
immediately upon notice of the adjustment to Customer.

      2.7   SERVICE INVOICES.  On or about the first day of each month, 
beginning with the first month which commences after the Substantial 
Completion Date, the Supplier shall deliver to the Customer a monthly invoice 
which reflects any Consumption Charges for the prior month just ended.  
Beginning with the first invoice delivered following the Commencement Date, 
such invoice shall also reflect the Contract Capacity Charge for the month 
then beginning and any other amounts then owing by the Customer under this 
Agreement.  In the event that the 



Commencement Date is a date other than the first day of a calender month, 
then the first invoice for Contract Capacity Charges shall also include a 
prorated Contract Capacity Charge for the portion of the immediately 
preceding month occurring after the Commencement Date.  In the event that the 
term of this Agreement ends on a date other than the first day of a calender 
month, then the Contract Capacity Charge for the final month shall be 
prorated accordingly.

      2.8   PAYMENT.  Payment of each invoice shall be due in full, on or 
before the thirtieth (30th) day following the date each invoice is received 
by the Customer (each a "Due Date").  The Customer shall make each payment 
invoiced by the Supplier when due without any further notice or demand, 
without offset of any kind, and irrespective of dispute to the amount of such 
invoice or otherwise, except as provided for in Section 6.1(b).  In addition 
to any actions which the Supplier may take during the continuance of a 
Customer Default, whether at law or in equity or otherwise, a service charge 
shall be imposed if payment of an invoice is not received within thirty (30) 
days after such invoice is delivered to the Customer equal to one and 
one-half percent (1.50%) per month, or the maximum legal rate, whichever is 
less, on the unpaid balance of such invoice for the period from the fifteenth 
(15th) day after such invoice was delivered through and including the date of 
payment thereof (calculated using actual days elapsed and a year of 365 or 
366 days, as applicable).

      2.9   TAXES.  In addition to the Contract Capacity Charges and the 
Consumption Charges payable hereunder, the Customer will pay all Taxes, 
including, without limitation, any Taxes which the Supplier is required to 
collect, except to the extent that such Taxes have been included in 
determining the Contract Capacity Charges then payable.
                                       
                                   ARTICLE 3
                MAINTENANCE OF EQUIPMENT, SYSTEMS AND METERS

      3.1   MAINTENANCE OF SUPPLIER INTERCONNECTION EQUIPMENT.

            (a)   At all times while this Agreement is in force, the Supplier 
shall operate and maintain the Supplier Interconnection Equipment, in 
accordance with the O&M Specifications.  If any of the Supplier 
Interconnection Equipment is damaged or destroyed as a direct result of the 
acts of the Customer or its agents, employees, tenants, customers, 
contractors or other Persons for whom the Customer is responsible, then the 
Customer shall be liable for the cost of the required repair or replacement.



            (b)   The Supplier, its agents and employees will not authorize 
or knowingly permit any Person, except a duly authorized employee or agent of 
the Supplier or the Customer, to operate, maintain, alter or otherwise affect 
the Supplier Interconnection Equipment or any component thereof or any 
equipment of the Customer, to break or replace any seal or lock of the 
Supplier or the Customer, or to alter or interfere with the operation of any 
item of equipment installed by the Customer.

            (c)  The Supplier will not modify the Supplier Interconnection 
Equipment in any material respect without the prior written consent of the 
Customer, which consent shall not be unreasonably withheld.  The Supplier's 
operations or equipment shall not adversely affect the Customer's ability to 
receive the Services in accordance with the provisions hereof and the 
Exhibits attached hereto and, in the event they do, the Supplier shall, at 
its own expense, except as set forth in Section 3.2, make such reasonable 
changes in its operations or equipment as are necessary to restore capacity 
in respect of the Services.

      3.2   CUSTOMER'S EQUIPMENT.

                  The Customer will notify the Supplier of substantial 
modifications it makes to the operating equipment and systems of the Premises 
and will be responsible for the maintenance of such equipment and systems.  
The Customer will not modify its equipment so as to adversely affect the 
Supplier's ability to deliver or the Customer's ability to receive the 
Services, or, if it does, the Customer shall, at its own expense, make such 
reasonable changes in its equipment as are necessary to permit the Supplier 
to deliver, and the Customer to receive, the Services in the capacities 
required hereby.

      3.3   METERING.

            (a)   The Supplier will provide metering equipment to measure the 
delivery of electricity to the Customer, the quantity of chilled water and 
hot water delivered to the Customer and the temperature at the Chilled Water 
Delivery Points and the Hot Water Delivery Points, respectively, of the 
chilled water and hot water being delivered to, and returned by, the 
Customer. Electrical meters shall be placed on the secondary site of each 
transformer, and the results of the electrical metering shall be based on 
coincidental demand. All metering equipment will be furnished, paid for, 
owned and maintained by the Supplier.  All such metering equipment shall be 
of the type which provides, and preserves a continuous flow of the relevant 
data 



twenty four (24) hours per day; all parties shall have full right of access 
to all such data and printouts thereof at all times and without reference to 
the other parties.  The Supplier will regularly test its metering equipment 
in accordance with the manufacturer's recommendations but not less than two 
(2) times per year and, if requested by the Customer, will conduct such tests 
in the presence of a representative of the Customer.  All testing shall 
include recalibration.  If requested by the Customer, the Supplier will 
conduct such testing on additional occasions; PROVIDED, that unless such 
testing indicates that the tested equipment provides metering results which 
are inaccurate by three percent (3%) or more with respect to water or by 
one-half of one percent (0.5%) or more with respect to electricity in a 
manner which is adverse to the Customer, the Customer will pay all 
out-of-pocket costs and expenses incurred by the Supplier in conducting such 
additional tests.  The Supplier will maintain an accurate log or record of 
all tests, whether initiated by the Supplier or the Customer, and will make 
the results of such tests available in a comprehensible manner to the 
Customer promptly upon request.

            (b)   If any test of the metering equipment reveals equipment 
that has failed to accurately record consumption of the Services metered 
thereby, the Supplier shall restore such metering equipment to a condition of 
accuracy or replace it.  If the metering equipment is in error by three 
percent (3%) or more with respect to water or by one-half of one percent 
(0.5%) or more with respect to electricity, then the Supplier will repair or 
replace such defective metering equipment within a reasonable period after 
receiving notice or becoming aware thereof and an adjustment shall be made in 
respect of the Consumption Charges for such Service in accordance with clause 
(d) below.

            (c)   The regular meter reading and billing period will be 
monthly. If more than one meter is installed on the Premises, the readings of 
all meters will be used in calculating the invoice with respect thereto.

            (d)   If the Supplier's metering record is interrupted at any 
time for any reason, or is found to be inaccurate and in need of repair or 
replacement under Section 3.3(b), the measurement of Services to be billed 
for such period of interruption, or for the period from the last test of the 
affected meters which shows them to have been operating within the acceptable 
limits of error under Section 3.3(b) through the date upon which such meters 
are corrected, will be estimated by the Supplier, acting reasonably, based 
upon past Customer usage during a similar period and under similar conditions 
if such information is available (and if such information is not available, 
based upon fuels consumed during such period and any other relevant 
information and/or bases which may reasonably be used for such 



purpose in the circumstances), and the Customer will pay invoices during such 
period based on the estimated measurement; subject to the Customer's right to 
withhold up to $12,500 in the aggregate from invoices based on estimates in 
any such period and dispute the same in good faith if the Customer reasonably 
disagrees with such estimated measurement.

            (e)   The Customer will provide to Supplier, without charge, 
adequate space, power and access on the Premises for the housing and 
maintenance of all metering and related equipment and other equipment related 
to the delivery of Energy which the Supplier provides to comply with its 
obligations hereunder; PROVIDED, however, that the Supplier shall act in 
accordance with all reasonable safety and security rules, regulations and 
policies then in effect on the Customer's property or other reasonable rules 
or requirements which the Customer may impose, and the Supplier's use shall 
in no way materially adversely affect the Customer's other activities at the 
Premises.

                   REPRESENTATIONS, WARRANTIES AND COVENANTS

      4.1   MUTUAL REPRESENTATIONS.

            (a)   Each party represents and warrants to the other that it has 
the requisite limited-liability company capacity to enter into this Agreement 
and fulfill its obligations hereunder, that the execution and delivery by it 
of this Agreement and the performance by it of its obligations hereunder have 
been duly authorized by all requisite action of its members, and by its board 
of directors or other governing body, and that, subject to compliance with 
any applicable regulatory laws or regulations governing the sale or delivery 
of the Services, the entering into of this Agreement and the fulfillment of 
its obligations hereunder does not contravene any law, statute or contractual 
obligation of the party giving the representation or warranty.

            (b)   Each party represents and warrants to the other that no 
suit, action or arbitration, or legal administrative or other proceeding is 
pending or has been threatened against the representing party that would 
affect the validity or enforceability of this Agreement or the ability of the 
representing party to fulfill its commitments hereunder, or that could result 
in any material adverse change in the business or financial condition of the 
representing party.



      4.2   SUPPLIER REPRESENTATIONS.  The Supplier hereby represents and 
warrants to the Customer that, as of the date of this Agreement, the Supplier 
is an indirect wholly-owned subsidiary of Unicom Corporation.

      4.3   SUPPLIER COVENANTS. 

            (a)   CONTINGENCY PLAN.  The Supplier covenants that it shall be 
responsible for developing a written contingency plan, with the technical 
assistance of the Customer, setting forth an agreed upon process for dealing 
with interruptions to Services, which contingency plan shall have as its goal 
minimizing the duration and effect of such interruptions to Services.  
Because the contingency plan may require the purchase or lease of equipment, 
the parties shall use their best efforts to agree upon the contingency plan 
on or before the date upon which the "Guaranteed Maximum Plant Price" is 
fixed under the Development Agreement.  If the parties are unable to agree 
upon the contingency plan on or before such date, then the Supplier shall be 
entitled to require an increase in the Guaranteed Maximum Plant Price with 
respect to any items required by the final contingency plan agreed upon which 
terms were not included in determining the Guaranteed Maximum Plant Price.  
In order to facilitate the process of establishing the contingency plan, 
within 120 days after the date of receipt of the Notice to Proceed by the 
Supplier, the Supplier will prepare an initial draft thereof and provide the 
same to the Customer, which, within fifteen (15) days of receipt thereof, 
shall review the same and provide written comments with respect thereto to 
the Supplier, or, if the Customer deems such plan to be satisfactory, then 
the Customer shall provide written confirmation of such satisfaction to the 
Supplier within such fifteen (15) day period.  (In the absence of any written 
comments from the Customer within such fifteen (15) day period, the Supplier 
shall be entitled to presume that the Customer is satisfied with such plan as 
provided.)  In the event that the Customer provides comments, the parties 
will meet to review the same and seek in good faith to incorporate such 
comments into the agreed final plan.

            (b)   OWNERSHIP OF NORTHWIND. The Supplier covenants that it 
shall not permit any transfer of any membership interest in the Supplier by 
the sole member of the Supplier as of the date of this Agreement, and not to 
issue any new membership interests in the Supplier, except as provided for in 
Section 10.2, without the prior written consent of the Customer (such consent 
not to be unreasonably withheld).

            (c)   THIRD PARTY ENERGY SERVICE AGREEMENTS.    The Supplier 
covenants that it shall not modify the Energy Service Agreement entered into 
by the 



Supplier with Music without Customer's prior written consent, provided such 
consent is not unreasonably withheld (provided, however, that Customer's 
consent shall not be required in the event of a Payment Default), and that 
such Agreement is in force substantially identical to this Agreement.
                                       
                                   ARTICLE 5
                           ADDITIONAL AGREEMENTS

      5.1   CONDITIONS PRECEDENT TO EFFECTIVENESS.

            (a)   The Supplier and the Customer agree that this Agreement and 
the obligations of the parties hereunder shall not become effective until 
each of the following conditions has been satisfied:

                  (i)   all exhibits to this Agreement shall have been agreed 
upon in definitive form, initialed by the parties and attached hereto, it 
being agreed and acknowledged that certain of the exhibits attached hereto on 
the date of execution of this Agreement have been identified as "preliminary" 
and are subject to further refinement as agreed by the parties, within 
specified applicable time limits identified herein, in connection with 
finalization of the plans and specifications for the Premises;

                  (ii)  the Supplier shall have entered into a construction 
agreement in form and terms reasonably satisfactory to the Supplier providing 
for the construction of the Northwind Facilities; and

                  (iii) Financial Closing shall have occurred and the 
Customer shall have become the fee owner of the "Aladdin Lands" (as such term 
is defined in the Development Agreement), subject to any  Customer 
obligations to convey portions thereof to Bazaar and Music.

            (b)   In addition, it shall be a condition precedent to the 
initial obligation of the Supplier to deliver any Service hereunder on the 
date when such Service is first required to be provided by it hereunder  that 
(i) the Customer shall have complied in all material respects with all of its 
covenants and Agreements contained herein to be complied with during the 
period from the date hereof to the date upon which such Service is to be 
delivered, and (ii) the Customer shall have provided to the Supplier evidence 
reasonably satisfactory to the Supplier that the Customer has obtained or is 
or will use all reasonable efforts to obtain all clearances, permits, 
licenses and approvals which are necessary for the Customer to construct 



and/or operate the Premises as contemplated hereby and receive such Services 
from the Supplier as of such date.

            (c)   In addition, it shall be a condition precedent to the 
initial obligation of the Customer to receive any Service hereunder on the 
date when such Service is first required to be provided hereunder or to pay 
Contract Capacity Charges or Consumption Charges otherwise required to be 
received by it hereunder  that: (i)  the Supplier shall have complied in all 
material respects with all of its covenants and Agreements contained herein 
to be complied with during the period from the date hereof to the date when 
such Service is to be delivered, and (ii) the Supplier shall have provided to 
the Customer evidence reasonably satisfactory to the Customer that the 
Supplier has obtained or will use all reasonable efforts to obtain all third 
party clearances, permits, licenses and approvals which are necessary for the 
Supplier to construct and/or operate the Northwind Facilities as contemplated 
hereby.

      5.2   INSURANCE.  The respective insurance requirements for the 
Supplier and the Customer are set forth in Exhibit E attached hereto, and 
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 E, except as set forth in 
below in this Section 5.2.  All insurance policies required by this Section 
shall provide that such policies may not be cancelled or terminated without 
thirty (30) days prior written notice to the Customer, Customer's lenders and 
the Supplier.  All liability insurance policies of Supplier and all insurance 
policies of Customer shall name the Customer's lender as an additional 
insured.

            Each party hereto agrees that the insurance described above to be 
provided by the other party may be provided through blanket coverages which 
may be provided in whole or in part through a policy or policies covering 
other liabilities and locations of the party obligated to provide such 
insurance and its affiliates.

            Each party hereby releases, to the extent legally possible for it 
to do so without invalidating its insurance coverages, for itself and 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 Aladdin Lands 
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 
this Section 5.2, irrespective of any negligence on the part of the 



released party and its respective officers, directors, agents, members, 
partners, servants or employees, which may have contributed to or caused 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 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 paragraph, 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 
party (or its respective officers, directors, agents, members, partners, 
servants and 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 5.2.

      5.3   CONFIDENTIAL INFORMATION.  The Customer and the Supplier each 
agree to treat in confidence all information regarding this Agreement and the 
performance by the parties of their obligations hereunder and all information 
which either the Customer or the Supplier will have obtained from the other 
party in contemplation of entering into, or in the performance of, this 
Agreement and not make any use of any of such information for any purpose 
other than complying with its obligations under this Agreement and the 
Related Agreements.  Such information will not be communicated to any Person 
other than the Customer, the Supplier, Aladdin Bazaar, LLC and Aladdin Music, 
LLC and their respective officers, directors, employees, members, agents, 
attorneys and professional consultants, except to the extent disclosure of 
such information:

            (a)   is required by law or governmental authority;

            (b)   is made by a party pursuant to litigation in which such 
party is a party;



            (c)   is made to any lender or prospective lender to such party
(PROVIDED such lender or prospective lender agrees in writing to keep such
information confidential on the terms set forth in this Section 5.3); or

            (d)   is made to a Person under contract with the disclosing party,
or to which the disclosing party wishes to sell or assign all or part of its
business or an equity interest in such Person in a transaction permitted hereby,
which Person has given a confidentiality undertaking which is substantially
similar to this one.

If either party is required to disclose confidential information pursuant to 
clause (a) above, such party will take reasonable steps to limit the extent 
of the disclosure and to make such disclosure confidential under the 
circumstances and will, to the extent it reasonably can do so in the 
circumstances, afford the other party hereto notice of such request for 
disclosure so as to permit such other party to seek an appropriate protective 
order or other means by which such information may be maintained in 
confidence pursuant to such disclosure. Information provided by a party 
hereunder will remain the sole property of the party providing such 
information.  The obligation of each party to treat in confidence, and not to 
use, information which it will have obtained from the other party will not 
apply to any information which (x) is or becomes available to such party from 
a source not otherwise under obligations of confidentiality with respect 
thereto, other than the party providing such information, or (y) is or 
becomes available to the public other than as a result of disclosure by such 
party or its agents in breach of this Section 5.3.

      5.4   FINANCIAL INFORMATION.  The Customer agrees to provide to the 
Supplier from time to time the following financial information concerning the 
Customer:

            (a)   copies of all definitive documentation governing 
indebtedness incurred by the Customer to finance (or refinance) the 
construction of the Premises;

            (b)   until such time, if ever, as the Customer becomes a 
reporting company under the Securities Exchange Act of 1934, as amended (or 
any successor statute thereto), copies of all monthly, quarterly and annual 
financial statements and forecasts which the Customer is obligated to provide 
to its lenders or to the trustee in respect of the  13.5% Senior Discount 
Notes Due 2010 to be issued by certain Affiliates of the Customer, which 
financial statements and forecasts will be provided concurrently or promptly 
after they are provided to such lenders and/or such trustee;



            (c)   in the event that the Customer or its parent entity shall 
file a registration statement under the Securities Act of 1933, as amended 
(or any successor statute thereto), the Customer will provide a copy of such 
registration statement (including any preliminary prospectus contained 
therein) to the Supplier promptly after the same has been filed with the 
United States Securities and Exchange Commission, or any successor entity 
thereto (the "SEC"); and

            (d)   from and after the date, if ever, upon which the Customer 
or its parent entity shall become a reporting company under the Securities 
Exchange Act of 1934, as amended (or any successor statute thereto), in lieu 
of the financial statements required by the preceding clause (b), the 
Customer will provide to the Supplier, by hard copy or electronically, 
promptly after filing of the same with the SEC, copies of all reports and 
financial statements filed with the SEC, including, but not limited to, any 
reports on any of Form S-K, Form 10-K or Form 10-Q and any annual reports to 
shareholders.

All such financial information, other than information which is contained in 
filings with the SEC, shall be received and held in confidence and shall not 
be used or disclosed by the Supplier except as permitted by Section 5.3 
hereof with respect to the confidential information provided by the Customer 
to the Supplier.

      5.5   TRANSFER OF INFORMATION TO CUSTOMER PURSUANT TO SALE.  The 
Supplier hereby agrees that in the event that the Customer acquires the 
Northwind Facilities pursuant to Section 6.3, 6.4 or 9.3, the Supplier will 
provide the Customer with copies of all specifications, manufacturers' 
warranties, design drawings, operating manuals and maintenance records for 
the Northwind Facilities, as well as other information concerning the design, 
operation and maintenance of the Northwind Facilities which are in the 
possession or control of the Supplier and which are relevant or reasonably 
necessary to the Customer's ownership or operation of the Northwind 
Facilities and will transfer to the Customer all of the Supplier's right, 
title and interest in and to such materials and items, which transfer shall 
be without recourse and without representation or warranty as to title to any 
such materials or items.

      5.6   FUEL AND ELECTRICITY ARRANGEMENTS.  From time to time, as the 
Customer may reasonably request, the Supplier shall provide the Customer with 
information concerning the Supplier's arrangements then in effect with 
respect to the purchase of fuels for use in providing Services hereunder and 
with respect to obtaining electricity from third party providers.  The 
Supplier agrees that it shall use 



best efforts to obtain economical and reliable sources of fuels and 
electricity from third party providers.

      5.7   REGULATORY COMPLIANCE RE ELECTRICITY.

            (a)   The provisions of this Section 5.7 shall not in any way 
affect the obligation of the Supplier to construct and demonstrate "Final 
Completion" (as such term is defined in the Development Agreement) of the 
Northwind Facilities, or to provide Chilled Water Service or Hot Water 
Service or to procure and provide to the Customer electricity up to the 
Specified Demand Amount applicable from time to time under this Agreement.  
The parties acknowledge that the generation, distribution, transmission 
and/or sale of Electricity Services by the Supplier hereunder may cause the 
Supplier and/or its Affiliates to be subject to compliance with or obtaining 
exemption from certain federal and Nevada laws and regulations.  The Supplier 
agrees, for itself and its Affiliates, subject to Section 5.7(b) hereof, to 
comply with, or obtain the necessary exemption from, any applicable laws and 
regulations affecting the Supplier's generation, distribution, transmission 
and/or sale of Electricity Services hereunder such that, on the Substantial 
Completion Date, the Supplier will lawfully be able to provide, or cause to 
be provided, such Electricity Services to the Customer.  The Customer, in 
turn, agrees to comply with any request of the Supplier which the Customer, 
in its good faith judgment, deems reasonable in connection with such 
regulatory compliance, including, without limitation, a request to amend this 
Agreement, the Lease or the Development Agreement in any way reasonably (in 
the good faith judgment of the Customer) necessary in the circumstances, so 
long as, as a result thereof, (i) the reliability of the Electric Services 
provided to the Customer is not adversely affected, (ii) the Supplier's 
responsibility to comply with its obligations in accordance with this 
Agreement, the Development Agreement and the Lease remains in full force and 
effect, (iii) the fees paid by the Customer pursuant to this Agreement are 
not increased, and (iv) the Customer's costs and expenses of any such action 
will be borne solely by the Supplier, providedthat this subsection (iv) shall 
not apply to the extent such action becomes reasonably necessary, in whole or 
in part, as a result of a change in the Customer's circumstances.

            (b)   The Customer agrees that, provided the Supplier uses best 
efforts to comply or obtain any necessary exemption from any applicable 
federal and Nevada laws and regulations, the Supplier need not become a 
"public utility" under Nevada law in order to comply with its obligations 
under this Agreement and Unicom Corporation need not, solely as a result of 
Supplier's compliance with its obligations under this Agreement, become a 
registered holding company pursuant to 



the Public Utility Holding Company Act of 1935 ("PUHCA"), as amended.  
Subject to the foregoing, the Customer and the Supplier agree to the 
following:

                  (i)   Notwithstanding any other provisions in this Agreement,
      from the Substantial Completion Date to March 1, 2000, the Supplier shall
      only be obligated to provide the Customer with electricity produced by the
      Northwind Facilities;

                  (ii)  The Supplier shall use best efforts to ensure that on or
      before March 1, 2000 it will be able to provide to the Customer, pursuant
      to the terms of this Agreement, the Electricity Services as defined in
      Section 2.1; best efforts shall not include requiring the Supplier to
      become a "public utility" under Nevada law, but shall include, if
      necessary to meet the Supplier's obligations, certification of the
      Northwind Facilities as a "Qualifying Facility" as defined in the Public
      Utility Regulatory Policies Act of 1978, as amended, and the regulations
      implementing such Act promulgated by the Federal Energy Regulatory
      Commission, as amended; provided that in order to certify the Northwind
      Facilities as a Qualifying Facility, the Supplier shall be permitted to
      transfer a membership interest in the Supplier to a third party, provided
      the Supplier obtains the Customer's prior written approval, such approval
      not to be unreasonably withheld or delayed, and provided the Supplier
      allows the Customer the right of first refusal to acquire the requisite
      membership interest in the Supplier;

                  (iii) For so long as the Supplier is lawfully able to do so
      without becoming a "public utility" under Nevada Law, after March 1, 2000,
      the Supplier shall provide the Customer its Electricity Services, which
      shall include both electricity generated by the Supplier and electricity
      otherwise obtained by the Supplier for the Customer; provided, however
      that such electricity not generated by the Supplier shall be provided by
      the Supplier to the Customer pursuant to and as part of this Agreement; or

                  (iv)  In the event the Supplier, despite its best efforts, is
      unable to provide the Electricity Services without becoming a "public
      utility" under Nevada Law or a registered holding company under PUHCA,
      then after March 1, 2000:

                        1.    the Supplier shall sell to the Customer and the
            Customer shall purchase from the Supplier all electricity generated
            by the Northwind Facilities;



                        2.    the Supplier shall be required to obtain on its
            own behalf, from a third party, electricity required to serve the
            Northwind Facilities;

                        3.    the Customer shall contract with a third party of
            its choosing to supply the Customer with the electricity required by
            the Customer not generated by the Supplier at the Northwind
            Facilities.  Such contract shall be of the shortest term practicable
            to ensure that the rates, terms and conditions thereof are
            commercially reasonable (and the Customer and the Supplier shall use
            reasonable efforts to coordinate their purchases under clauses (iv)2
            and (iv)3 to seek to obtain advantageous  rates);

                        4.    the Supplier guarantees to the Customer that the
            blended rate paid by the Customer after March 1, 2000 for
            electricity, such blended rate to include the rate paid by the
            Customer to the Supplier and by the Customer to the third party
            Supplier pursuant to the previous subparagraph 3, shall be lower
            than the rate then charged by Nevada Power Company to customers with
            a load comparable to the Customer's load (the "Rate Standard").  The
            Customer shall provide the Supplier with yearly statements, if
            applicable, establishing that the blended rate paid by the Customer
            for such year was not lower than the Rate Standard for such year. 
            In such event, and within thirty (30) days of receipt of such
            statement, the Supplier shall make a payment to the Customer
            sufficient to give the Customer a blended rate which is lower than
            the Rate Standard. 

            (v)   The Customer agrees that in the event the Supplier
      subsequently becomes able to provide the total Electric Services to the
      Customer without being considered a "public utility" under Nevada law,
      then the Customer shall purchase the total Electricity Services from the
      Supplier in accordance with the terms of this Agreement upon the
      expiration of any third party contract(s) described above in Section
      5.7(b)(iv)(3) then in effect.

                                   ARTICLE 6
                           DEFAULTS AND REMEDIES

      6.1   SUPPLIER DEFAULTS.



            (a)   PERFORMANCE FAILURES.

                  (i)   the occurrence of any of the following events shall
constitute a "Performance Failure":

                        1.    if, at any time after the Substantial Completion
            Date and for any reason other than a Force Majeure Event, chilled
            water is not provided to the Supplier's side of the Chilled Water
            Delivery Point at 13,905 gallons per minute and 42 degrees
            Fahrenheit or lower;

                        2.    if, at any time after the Substantial Completion
            Date and for any reason other than a Force Majeure Event, hot water
            is not provided to the Supplier's side of the Hot Water Delivery
            Point at 2882 gallons per minute and 200 degrees Fahrenheit or
            higher; or

                        3.    if, at any time after the Initial Services Date
            but prior to the Substantial Completion Date for any reason other
            than a Force Majeure Event, chilled water is not provided to the
            Supplier's side of a Chilled Water Delivery Point at 4800 gallons
            per minute and 46 degrees Fahrenheit or lower.

                  (ii)  ACTIONS TO BE TAKEN.  Promptly upon becoming aware of a
Performance Failure (whether by notice thereof from the Customer or by the
Supplier's monitoring of its systems and the operation of the Northwind
Facilities or otherwise) the Supplier shall:

                        1.    immediately seek to determine the cause of such
            Performance Failure and shall apprise the Customer of the Supplier's
            conclusion as to such cause as quickly as possible and provide the
            Customer with a corrective action plan consistent with the
            Contingency Plan, which the Supplier will implement at its sole cost
            and expense where the Performance Failure is for any reason other
            than a Force Majeure Event, except that such implementation with
            respect to a Performance Failure described in Section 6.1(a)(i)3
            will be at the Customer's expense, and use its best efforts to
            accommodate any changes thereto which the Customer reasonably
            requests;



                        2.    commence implementation of such corrective action
            plan, using all best efforts to correct or cure such Performance
            Failure in the shortest period of time;

                  (iii) ADDITIONAL MEASURES.  In addition to the above,
immediately upon becoming aware of a Performance Failure, Supplier shall allow
Customer or Customer's agents immediate access to the Northwind Facilities and
permit Customer full inspection rights of the Northwind Facilities.

            (b)   SERVICE FAILURES.

                  (i)   the occurrence of any of the following events shall
constitute a "Service Failure":

                        1.    if, at any time after the Substantial Completion
            Date and for any reason other than a Force Majeure Event, chilled
            water is not provided to the Supplier's side of the Chilled Water
            Delivery Point at 13,905 gallons per minute and 44 degrees
            Fahrenheit or lower;

                        2.    if, at any time after the Substantial Completion
            Date and for any reason other than a Force Majeure Event, hot water
            is not provided to the Supplier's side of the Hot Water Delivery
            Point at 2882 gallons per minute and 190 degrees Fahrenheit or
            higher;

                        3.    if, at any time after the Substantial Completion
            Date and for any reason other than a Force Majeure Event, primary
            and secondary AC electricity (up to and including the initial
            transformation) delivered to an Electricity Delivery Point is less
            than the Specified Demand Amount then in effect; 

                        4.    if, at any time after the Initial Services Date
            but prior to the Substantial Completion Date for any reason other
            than a Force Majeure Event, chilled water is not provided to the
            Supplier's side of the Chilled Water Delivery Point at 4800 gallons
            per minute and 48 degrees Fahrenheit or lower; or

                        5.     if any Performance Failure exists for any seventy
            two (72) hours of any ninety six (96) hour period.



                  (ii)  ACTIONS TO BE TAKEN.  Promptly upon becoming aware of a
Service Failure (whether by notice thereof from the Customer or by the
Supplier's monitoring of its systems and the operation of the Northwind
Facilities or otherwise) the Supplier shall:

                        1.    immediately seek to determine the cause of such
            Service Failure and shall apprise the Customer of the Supplier's
            conclusion as to such cause as quickly as possible and provide the
            Customer with a corrective action plan consistent with the
            Contingency Plan, which the Supplier will implement at its sole cost
            and expense where the Service Failure is for any reason other than a
            Force Majeure Event, except that such implementation with respect to
            a Performance Failure described in Section 6.1(b)(i)4 will be at the
            Customer's expense, and use its best efforts to accommodate any
            changes thereto which the Customer reasonably requests;

                        2.    commence implementation of such corrective action
            plan, using all best efforts to correct or cure such Service Failure
            in the shortest period of time;

                        3.    if the Supplier believes that correcting or curing
            such Service Failure requires or can reasonably be anticipated to
            require more than eight (8) hours from the time either party became
            aware of the Service Failure, promptly notify the Customer of the
            same and advise the Customer of the efforts which the Supplier
            believes will be necessary to accomplish such correction or cure,
            the probable timetable for doing so and any load management
            adjustments which the Supplier believes will be helpful to
            minimizing the impact of such Service Failure on the operation of
            the Premises; and

                        4.    if the Supplier believes that correcting or curing
            such Service Failure requires or can reasonably be anticipated to
            require more than twenty four (24) additional hours (thirty two (32)
            hours from the time either party became aware of the Service
            Failure), and the Customer believes that the Premises cannot be
            operated in a reasonably normal manner due to such ongoing Service
            Failure, Supplier shall procure, at its own expense (but without
            reduction of the Contract Capacity Charges and Consumption Charges
            hereunder except to the extent each reduction is mandated by Section
            6.1(c)(ii) 



            below), substitute Services (meaning, for example, in the case of 
            Chilled Water Services or Hot Water Services, portable temporary 
            chillers or boilers) in accordance with the Contingency Plan to be 
            brought to the site and put into operation as quickly as possible.

                  (iii) ADDITIONAL MEASURES.  In addition to the above, 
immediately upon becoming aware of a Service Failure, Supplier shall allow 
Customer or Customer's agents immediate access to the Northwind Facilities 
and permit Customer full inspection rights of the Northwind Facilities.  If 
Customer identifies the cause of such Service Failure and requires corrective 
action or cure, Supplier shall either promptly take such corrective action or 
promptly make such cure, or permit the Customer to take any action reasonably 
intended to correct or cure such Service Failure  at the Supplier's sole cost 
and expense (except that, other than as provided in Section 6.1(c)(ii) below, 
the Customer shall remain liable for the Contract Capacity Charge) and/or 
assume control of the Northwind Facilities and maintain such control until 
the Service Failure has been cured or corrected.

            (c)   SERVICE DEFAULTS.  If any Service Failure other than a 
Service Failure under Section 6.1(b)(i)(4) continues for any thirty two (32) 
hours of any forty eight (48) hour period, it shall be deemed a "Service 
Default" and the following additional provisions shall apply:

                  (i)   CONTROL OF NORTHWIND FACILITIES.  The Customer shall 
have the right to assume control of the Northwind Facilities and maintain 
such control until such Service Default has been cured or corrected and take 
any action reasonably intended to correct or cure such Service Default at the 
Supplier's sole cost and expense (except that, other than as provided in 
Section 6.1(c)(ii) below, the Customer shall remain liable for the Contract 
Capacity Charge).

                  (ii)  ABATEMENT.  The Customer shall be entitled to an 
abatement of the Contract Capacity Charge for the month during which such 
Service Default has occurred in an amount equal to (A) the Contract Capacity 
Charge then in effect for such month multiplied by a fraction, the numerator 
of which shall be the number of days during which such Service Default has 
occurred during such month and the denominator of which shall be the number 
of days in such months, multiplied by (B) 70% if such Service Default was 
with respect to Chilled Water Service, or 9% if such Service Failure was with 
respect to Hot Water Service, or 21% if such Service Default was with respect 
to Electricity Service.  The amount of any applicable abatement of Contract 
Capacity Charges under this Section 6.1(b) shall be due and payable on the 
first day of the month following the month during which such 



Service Default shall have occurred and may be off-set by the Customer 
against the Contract Capacity Charge which is due and payable on such date 
with respect to the month then beginning.

                  (iii) RETAIN CONSULTANTS AND IMPLEMENT CONSULTANTS' 
RECOMMENDATIONS.  The Customer shall have the right to hire, at the expense 
of the Supplier, an independent consultant to review the circumstances 
involving the Service Default and make written recommendations as to 
reasonable corrective action (the "Consultants' Recommendations"), which 
shall be provided to the Supplier and promptly implemented by the Supplier at 
its sole expense (or, if the Customer has assumed control of the Northwind 
Facilities pursuant to Section 6.1(b)(i), may be implemented by the Customer 
at the Supplier's sole expense).

                  (iv)  TERMINATION OF AGREEMENT.  In the event that the 
Supplier fails to promptly implement the Consultants' Recommendations in 
accordance with a reasonable timetable agreed upon by the consultant, or to 
otherwise correct any Service Default (or provide substitute services 
reasonably acceptable to the Customer for the Services which are the subject 
of such Service Default) within the timetable reasonably recommended by such 
independent consultants, the Customer shall have the right to terminate this 
Agreement by not less than thirty (30) days' prior written notice to the 
Supplier specifying the effective date of termination, which shall be the 
date upon which Customer acquires the Northwind Facilities pursuant to 
Section 6.4.

            (d)   OTHER DEFAULTS.

                  (i)   In the event of failure, other than a Performance 
Failure, a Service Failure or a Service Default, by the Supplier to comply 
with or perform any agreement or obligation to be complied with or performed 
by the Supplier in accordance with this Agreement, which failure is not the 
result of actions or omissions of the Customer and which failure remains 
uncorrected or uncured thirty (30) days after notice of such failure is given 
to the Supplier by the Customer (or, if such failure is of such a nature that 
it cannot reasonably and with due diligence be corrected or cured within such 
thirty (30) day period and the Supplier commences action to correct or cure 
such default within such thirty (30) day period and thereafter diligently and 
without interruption or delay completes the correction or cure of such 
failure, such longer time as is necessary to complete such correction or 
cure, in no event to exceed one hundred eighty (180) days), the Customer 
shall have the right: (1) at the Supplier's sole cost and expense (except 
that, other than as provided in Section 6.1(c)(ii) below, the Customer shall 
remain liable for the Contract Capacity 



Charge), to take any action reasonably intended to correct or cure such 
failure; or (2) to terminate this Agreement by not less than thirty (30) 
days' prior written notice to the Supplier specifying the effective date of 
termination.

                  (ii)  TERMINATION WITHOUT PREJUDICE.  Any election by the 
Customer to terminate this Agreement under Section 6.1 shall be without 
prejudice to the other rights and obligations of the parties hereunder and 
shall not relieve the Supplier of its obligation to provide Services 
hereunder until the effective date of termination, but any subsequent 
correction by the Supplier of the event which is the basis for such notice of 
termination shall not be effective to cause rescission of the effectiveness 
of such termination unless the Customer shall otherwise agree at the time of 
the subsequent correction, provided that the Customer acquires the Northwind 
Facilities pursuant to Section 6.4.

      6.2   CUSTOMER DEFAULTS.  The occurrence at any time with respect to 
the Customer of any of the following events constitutes a Customer Default:

            (a)   failure by the Customer to make, within twenty five (25) 
days after the Due Date, any payment stated herein to be due from it 
hereunder (each, a "Payment Default"); provided, however, that failure to 
make a payment which results from the Customer's right of abatement pursuant 
to Section 6.1 hereof shall not be a Payment Default;

            (b)   except as otherwise excused pursuant to Section 7.1 hereof, 
failure, other than a Payment Default, by the Customer to comply with or 
perform any agreement or obligation to be complied with or performed 
exclusively by the Customer in accordance with this Agreement, which failure 
is not the result of actions or omissions by the Supplier, or Music, if such 
failure is not remedied on or before the 30th day after notice of such 
failure is given to the Customer and Music by the Supplier, provided if such 
default is of such a nature that it cannot reasonably and with due diligence 
be cured within such thirty (30) day period and the Customer commences to 
cure such default within such thirty (30) day period and thereafter 
diligently and without interruption or delay completes the cure of such 
default within a reasonable period of time, but in no event to exceed one 
hundred eighty (180) days, it will not constitute a Customer Default.

      6.3   REMEDIES UPON CUSTOMER DEFAULT. 

            (a)   In addition to any other remedies available at law or in 
equity, upon the occurrence of a Payment Default, the Supplier shall have the 
right, upon 



providing the Customer with an additional five (5) days' prior written notice 
(sixty (60) days from when the invoice was received by the Customer), to 
discontinue the supply of Services to the Customer until the Customer 
remedies such Payment Default; PROVIDED that if such Payment Default 
continues for a period of one hundred fifty (150) consecutive days (one 
hundred eighty (180) days from when the invoice was received) or more the 
Supplier, by written notice to the Customer, may terminate the Customer's 
right to cure such Payment Default by terminating this Agreement, without 
prejudice to the Supplier's claims in respect to such Payment Default and 
other rights accruing hereunder prior to such termination.

            (b)   In the event of a Customer Default, other than a Payment 
Default, which remains uncorrected or uncured thirty (30) days after notice 
of such Customer Default is given to the Customer by the Supplier (or if such 
Customer Default is of such a nature that it cannot reasonably and with due 
diligence be corrected or cured within such thirty (30) day period and the 
Customer commences action to cure or correct such Customer Default within 
such thirty (30) day period and thereafter diligently and without 
interruption or delay completes the correction or cure such Customer Default, 
such longer time as is necessary to complete such connection or cure, in no 
event to exceed one hundred eighty (180) days), the Supplier shall have the 
right to require the Customer to purchase the Northwind Facilities for a 
purchase price equal to the Make Whole Amount  at such time.

      6.4   CUSTOMER'S OBLIGATION TO PURCHASE UPON TERMINATION.  If the 
Supplier shall fail to comply with its obligations to correct any Service 
Default which it is obligated to correct hereunder and the Customer has given 
notice of termination of this Agreement pursuant to Section 6.1(b), Section 
6.1(c) or Section 6.1(d), then the Supplier shall thereupon be obligated to 
sell, assign and transfer, and the Customer shall thereby be obligated to 
purchase and acquire possession and ownership of the Northwind Facilities 
upon the effective date of termination for a purchase price (the "Payment 
Amount") equal to (a) the Supplier's investment in the Northwind Facilities, 
determined in accordance with Exhibit C, multiplied by a fraction the 
numerator of which shall be the number of months remaining in the Initial 
Term and the denominator of which shall be 240, minus (b) any costs incurred 
by Customer for required repair and/or maintenance.  The Payment Amount shall 
not provide for any return on Supplier's project investment.  (See 9.2)

            In such event, on such date of termination or as soon as 
reasonably possible, the Customer shall pay to the Supplier through escrow 
and by wire transfer of immediately available funds, an amount equal to the 
Payment Amount and shall, with respect to all contracts approved of by 
Customer in advance of their execution 



(which approval the Customer will consider in good faith) concurrently 
assume, and agree to indemnify and hold the Supplier harmless from, as of the 
date of such termination and for all periods thereafter, all obligations of 
the Supplier accruing on or after the date of termination under any contracts 
or Agreements with respect to the Northwind Facilities (excluding, however, 
at the option of the Customer, any such contract or agreement entered into 
with Nevada Power Company (or any wholly-owned subsidiary of Nevada Power 
Company), Boston Edison, Ontario Hydro, Houston Industries or UTT or any of 
their Affiliates which in Customer's sole discretion is deemed to be 
materially more onerous to the Supplier than a third party arm's length 
agreement for the same goods or services would be in the circumstances) under 
a written assignment and assumption agreement in form and substance 
reasonably satisfactory to the Supplier and its counsel, against delivery by 
the Supplier of possession of the Northwind Facilities and an executed bill 
of sale therefor in form and substance reasonably satisfactory to the 
Customer and its counsel.

      6.5   LENDERS' RIGHT TO CURE.  Each party hereto hereby agrees that in 
the event that the other party hereto shall make any assignment of its rights 
hereunder to any lender or lenders to whom such party provides a security 
interest in such party's right, title and interest in the Premises or the 
Northwind Facilities, as applicable, in connection with financing (or 
refinancing) the Premises or the Northwind Facilities, respectively, that 
each party will provide such lenders or the entity identified to the parties 
as having authority to act as the agent for such lenders with all notices 
given pursuant to this Agreement and that such lender or lenders shall have 
an additional ten (10) days to cure any failure by such party to comply with 
its obligations hereunder.  The Supplier agrees that it shall afford Music 
and Bazaar, and their lenders, identical cure rights.

      6.6   REMEDIES NOT EXCLUSIVE.  The right of the Customer to terminate 
this Agreement pursuant to Section 6.1 and to acquire the Northwind 
Facilities pursuant to Section 6.4 and the rights of the Supplier to cease 
providing Services and to terminate this Agreement and/or require the 
Customer to purchase the Northwind Facilities pursuant to Section 6.3 shall 
not be deemed to be exclusive and, except as expressly waived in Section 8.1 
and Section 8.2, shall be in addition to any and all other rights either of 
them may have at law or in equity for any default under Section 6.1(d) or any 
Service Default or Customer Default (as applicable) hereunder after notice 
and any opportunity to cure provided for herein.  The remedies provided 
herein for a Performance Failure or a Service Failure shall be the exclusive 
remedies until such failure or failures become a Service Default.



                                   ARTICLE 7
                                 FORCE MAJEURE

      7.1   FORCE MAJEURE.

            (a)   If either party hereto is prevented from or delayed in 
performing any of its obligations hereunder by reason of a Force Majeure 
Event, such party will notify the other party in writing as soon as 
practicable and will be excused from its obligations hereunder to the extent 
of such interference; PROVIDED, that no payment obligation hereunder will be 
excused or delayed as the result of a Force Majeure Event.

            (b)   The party whose performance hereunder is prevented or 
delayed as the result of a Force Majeure Event will use reasonable efforts to 
remedy its inability to perform; PROVIDED, however, nothing in this Section 
7.1(b) will be construed to require the settlement of any strike, walkout or 
other labor dispute with its employees on terms which are contrary to its 
interest.  The Supplier agrees however, that in the event of a strike, 
walkout or other labor dispute which may reasonably be expected to interrupt 
the providing of Services due to the Supplier's employees participating in or 
honoring such strike, walkout or dispute, (i) the Supplier, at Supplier's 
sole cost and expense (but without reduction in Contract Capacity Charges), 
shall use good faith efforts to operate the Northwind Facilities using 
management or other personnel which will not participate in or honor such 
strike, walkout or dispute, and (ii) if the Supplier will not be able to 
operate the Northwind Facilities using such management or other personnel, 
the Supplier will cooperate with the Customer to permit the Customer or its 
duly authorized representative, at Supplier's sole cost and expense (without 
reduction in Consumption Charges and Contract Capacity Charges), to operate 
the Northwind Facilities in such circumstances, PROVIDED that such operation 
is carried out by personnel which are, in the Supplier's reasonable judgment, 
adequately trained and experienced to operate the Northwind Facilities.

            (c)   CONDEMNATION.  In the event of a condemnation or eminent 
domain taking of all or part of the site upon which the Plant is to be 
located (a "Taking"), Supplier shall, as soon as practicable, determine 
whether it is commercially reasonable and technically feasible in the 
circumstances for Supplier to redesign, repair and/or restore the Northwind 
Facilities such that the Supplier can meet its obligations to provide 
Services to the Customer hereunder.  In the event Supplier determines that it 
is commercially reasonable and technically feasible, Supplier will so inform 
Customer, this Agreement shall remain in force and, to the 




extent set forth in Section 8.2 of the Northwind Lease, Supplier shall be 
entitled to the award or awards from such Taking and the Contract Capacity 
Charges payable hereunder thereafter shall be adjusted downward in an amount 
corresponding to any such award paid to the Supplier.  In the event that 
Supplier determines that it is not commercially reasonable or technically 
feasible in the circumstances to redesign, repair or restore the Northwind 
Facilities, then Supplier shall so notify Customer and such notice shall also 
constitute termination of this Agreement, effective on the date when such 
Taking shall effectively prevent Supplier from complying with its obligations 
to provide Services hereunder, and, to the extent set forth in Section 8.1 of 
the Northwind Lease, Supplier shall be entitled to the award or awards from 
such Taking.  Notwithstanding the foregoing, in the event Supplier and 
Customer disagree as to whether it is commercially reasonably and technically 
feasible in the circumstances for Supplier to redesign, repair or restore the 
Northwind Facilities, then Supplier and Customer shall promptly meet and use 
their best efforts to resolve such dispute.  If the Parties are unable to 
resolve such dispute within ten (10) days, then the Parties shall refer such 
dispute to the "Independent Engineer"(as defined in the Development 
Agreement). The Independent Engineer's conclusion as to whether it is 
commrcially reasonable and technically feasible in the circumstances for 
Supplier to redesign, repair or restore the Northwind Facilities shall be 
accepted by and binding upon the Parties.

            (d)   In the event of a Force Majeure Event of a nature such 
that, by implementation of the Contingency Plan (or a part thereof), Services 
may be provided to the Customer during the interruption caused by such Force 
Majeure Event, then, upon the Customer's request and at the Customer's 
expense, except as set forth in Section 7.1(b) above, the Supplier shall use 
its best efforts to implement the Contingency Plan (or portion thereof which 
is applicable) to mitigate the interruption of Services caused by such Force 
Majeure Event.

                                   ARTICLE 8
                                INDEMNIFICATION

      8.1   INDEMNIFICATION BY THE SUPPLIER.  The Supplier agrees to protect, 
indemnify and hold harmless the Customer Group Member from and against any 
and all Loss and/or Expense, 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), incurred by the Customer Group 
Member in connection with or arising from:

            (a)   any breach by the Supplier of its obligations hereunder;



            (b)   the installation, maintenance, operation, repair, removal, 
replacement or alteration of any portion of the Northwind Facilities or the 
Supplier's metering and other equipment and piping on the Premises, including 
the Supplier Interconnection Equipment, or any acts or omissions of the 
Supplier or those Persons under its direction or control in connection 
therewith; PROVIDED such Loss or Expense does not result from actions or 
omissions of the Customer or those Persons under its direction or control 
(including its agents and those which it has authorized or knowingly 
permitted to act on its behalf);

            (c)   any unauthorized operation, maintenance or alteration of, 
or action affecting, the Customer's equipment, or any component thereof, by 
the Supplier or those Persons under its direction or control (including its 
agents and those which it has authorized or knowingly permitted to act on its 
behalf); or

            (d)   any claims, obligations, damages, expenses or liabilities 
to third parties for personal injury or property damage to the extent they 
arise out of any legally actionable action of the Supplier or its agents, 
contractors or employees, or those Persons under its direction or control, 
PROVIDED that this indemnity shall not apply to the extent that the claim, 
obligation, damage, expense or liability arises from the negligence or 
willful misconduct of, or a breach of the Customer's obligations under this 
Agreement by, the Customer, its agents, contractors or employees, or those 
Persons under its direction or control;

but excluding any Loss or Expense arising from interruption of Services
permitted by Section 6.3(a) or Section 7.1.

      8.2   INDEMNIFICATION BY THE CUSTOMER.  The Customer agrees to protect, 
indemnify and hold harmless the Supplier Group Member from and against any 
and all Loss and/or Expense incurred by the Supplier Group Member in 
connection with or arising from:

            (a)   any breach by the Customer of its obligations hereunder;

            (b)   any acts or omissions of the Customer or those Persons 
under its direction or control; PROVIDED such Loss or Expense does not result 
from the acts or omissions of the Supplier or those Persons under its 
direction or control (including its agents and those which it has authorized 
or knowingly permitted to act on its behalf) or, other than as set forth in 
clause (c) below, any third Persons; or



            (c)   any claims, obligations, damages, expenses or liabilities 
to third parties for personal injury or property damage to the extent they 
arise out of any legally actionable action of the Customer or its agents, 
contractors or employees, or those Persons under its direction or control, 
PROVIDED that this indemnity shall not apply to the extent that the claim, 
obligation, damage, expense or liability arises from the negligence or 
willful misconduct of, or a breach of the Supplier's obligations under this 
Agreement by, the Supplier, its agents, contractors or employees, or those 
Persons under its direction or control.

      8.3   NOTICE OF CLAIMS.

            (a)   If a claim is asserted or action brought against an 
Indemnified Party and the Indemnified Party believes that it is entitled to 
indemnification under this Article 8, the Indemnified Party shall promptly 
notify the Indemnitor, in writing, of such claim or action.  Such notice 
shall be provided in sufficient time to enable the Indemnitor to assert and 
prosecute appropriate defenses to the claim or action; PROVIDED, that failure 
to give such notice shall not relieve the Indemnitor of its obligations 
hereunder except to the extent it will have been prejudiced by such failure.  
Upon the receipt of such notice, the Indemnitor shall make a prompt 
determination of whether it believes it is required to indemnify the 
Indemnified Party, and shall promptly notify the Indemnified Party, in 
writing, of its determination.  If the Indemnitor determines that it is 
required to indemnify, it shall assume the defense of the Indemnified Party, 
including the employment of counsel, and shall thereafter pay all costs and 
expenses relative to the defense of the claim or action.  The Indemnified 
Party shall cooperate with the Indemnitor in all reasonable aspect in this 
defense.  The Indemnified Party shall also have the right, at its own 
expense, to employ separate counsel in any such action and to participate in 
the defense thereof.  The Indemnitor shall not be liable for any settlement 
of any claim or action made without its consent.

            (b)   In calculating any Loss or Expense there will be deducted 
(i) the amount of any insurance recovery by the Indemnified Party in respect 
thereof (and no right or subrogation will accrue hereunder to any insurer) 
or, in the event that the Indemnified Party has failed to maintain any 
insurance coverage required by this Agreement to be maintained by such party 
or fails to make a timely claim under any applicable insurance, the amount of 
the insurance recovery which would reasonably be expected to have been 
received had such insurance been maintained and/or such claim been timely 
filed, and (ii) the amount of any tax benefit to the Indemnified Party (or 
any of its Affiliates) with respect to such Loss or Expense (after giving 
effect to the tax effect of receipt of the indemnification payments).



            (c)   After any Claim Notice has been given pursuant hereto, the 
amount of indemnification to which an Indemnified Party will be entitled

      9.1   TERM.

            (a)   Unless the Supplier has been given by Customer the Notice 
to Proceed on or before May 1, 1998 and the conditions precedent set forth in 
Section 5.1 hereof have been met to the Supplier's reasonable satisfaction on 
or before such date (or, with respect to any condition which the Supplier is 
willing to waive on or before such date, waived in a writing delivered to the 
Customer on or before such date), at any time thereafter the Supplier may 
terminate this Agreement and its obligations hereunder by written notice to 
the Customer, such termination to be effective immediately; provided, 
however, that upon Supplier's acceptance of the Notice to Proceed, Supplier's 
right to terminate this Agreement pursuant to this section shall be null and 
void, and no longer in effect.  In the event that the Development Agreement 
is terminated by Aladdin pursuant to Section 10(b) thereof, or by the 
Supplier pursuant to Section 2(k), Section 10(d) or Section 10(c) thereof, 
then this Agreement shall concurrently terminate and be of no further force 
or effect.

            (b)   Unless sooner terminated pursuant to clause (a) above or 
any of Section 6.1 or Section 6.4, Section 7.1(c) or Section 9.3, this 
Agreement will remain in effect for the Initial Term, and will continue in 
effect for each Renewal Term, if any; PROVIDED that there shall not be more 
than three (3) Renewal Terms hereunder.  Unless written notice that this 
Agreement will terminate on the last day of the then current Initial Term or 
Renewal Term is provided by either party at least twelve (12) months prior to 
the end of the then current Initial Term or Renewal Term, this Agreement will 
continue for an additional Renewal Term.

      9.2   EFFECT OF TERMINATION.  Upon the expiration or termination of this
Agreement:



            (a)   unless the Customer purchases the Northwind Facilities 
pursuant to Section 9.3 or directs the Supplier to remove the Northwind 
Facilities pursuant to Section 9.2(b) (in which case the Supplier shall so 
disconnect and remove the Northwind Facilities),  the Supplier shall abandon 
the Northwind Facilities as is and where is and shall have no further 
obligations under this Agreement or the Lease in respect thereof;

            (b)   if the Customer directs the Supplier to remove the 
Northwind Facilities, then the Supplier, at the Customer's expense (less any 
net proceeds of salvage or other disposition of the Northwind Facilities), 
will remove the Northwind Facilities and all Supplier Interconnection 
Equipment and any other property of the Supplier on the Premises in a prudent 
and workmanlike manner, and will repair and restore in a manner reasonably 
satisfactory to the Customer all damage to the Premises caused by such 
removal (and pay for such damage where caused by Supplier's negligence or 
wilful misconduct), and the Customer will provide the Supplier access to the 
Premises reasonably requested by the Supplier to allow the Supplier to remove 
such property in a timely fashion;

            (c)   the Customer will pay the Supplier all amounts then payable 
to the Supplier hereunder (including costs of removal under clause (b) above 
or, in the event the Customer is purchasing the Northwind Facilities under 
any of Sections 6.3, 6.4, or 9.3, the purchase price payable); and

            (d)   the Customer and the Supplier will have no further 
obligations hereunder other than (i) obligations accruing prior to the date 
of such termination or expiration, (ii) Customer's obligations to provide 
access rights pursuant to Section 9.2(b) and (iii) obligations under Section 
5.3 and Article 8, all of which will survive the expiration or termination of 
this Agreement.

      9.3   THE CUSTOMER'S OPTION TO PURCHASE.

            (a)   Each of the Customer and the other Customer Group Members 
shall have a continuing non-exclusive option to purchase the Northwind 
Facilities at any time prior to termination of this Agreement, exercisable by 
the Customer alone or together with one or both Customer Group Members by 
written notice given to the Supplier not less than one (1) year prior to the 
date upon which such purchase shall close as specified in such notice (the 
"Closing Date"), which notice shall state that the option under this Section 
9.3 is being exercised.  The purchase price payable upon such exercise shall 
equal the Make Whole Amount as of the date of such purchase.  The option 
granted hereby shall expire and be of no further force or effect 



on the earliest of (i) the expiration of the Term hereof, or (ii) the date 
upon which any other entity which has an option to purchase the Northwind 
Facilities effectively exercises such option.

            It shall be a condition to the Supplier's obligation to 
consummate the sale hereunder that concurrently with closing the Customer 
shall assume, and indemnify and hold the Supplier harmless from, all 
obligations of the Supplier accruing after the Closing Date under all 
contracts and Agreements with respect to the Northwind Facilities under which 
any performance obligations will continue following such sale and at the 
closing the Supplier shall assign and the Customer shall assume all such 
contracts and Agreements under a written assignment and assumption agreement.

            (b)   In the event that the Customer gives notice that it is 
exercising its option under this Section 9.3 to acquire the Northwind 
Facilities, then:

                  (i)   not less than ten (10) days nor more than six (6) 
months prior to the Closing Date, the Supplier shall obtain and deliver to 
the Customer payoff letters, in form and substance reasonably satisfactory to 
the Customer, from the holders of any Facilities Debt or any trustee or agent 
with power to act for such holders stating the principal amount of such 
Facilities Debt as of the Closing Date, any accrued interest thereon through 
such date, and any other amounts which shall be payable in respect thereof as 
of the Closing Date;

                  (ii)  not less than ten (10) days prior to the Closing 
Date, the Supplier shall provide to the Customer a written statement of the 
Make Whole Amount, determined as of the Closing Date, accompanied by 
appropriate detail. The Customer and its advisors shall be deemed to have 
accepted such statement unless written objection thereto is delivered to the 
Supplier within three (3) days after the date of receipt thereof by the 
Customer.  Any such written objection shall specify in reasonable detail the 
reasons therefor.  In the event of such objection, the Supplier and the 
Customer shall meet and try to reach agreement as to the Make Whole Amount, 
but if such agreement is not reached within five (5) days after the date upon 
which such written objections are received by the Supplier, then such matter 
shall be submitted to three outside accounting firms, one of which shall be 
the Customer's outside accounting firm, one of which shall be the Supplier's 
outside accounting firm, and the third of which shall be chosen by the first 
two firms, and such accounting firms shall each determine the Make Whole 
Amount and the two determinations which are closest together shall then be 
averaged and the average of such two determinations shall be the Make Whole 
Amount;



            (c)   Closing of the purchase shall occur on the Closing Date 
(or, if such day is not a business day, on the next following business day) 
or such other date as the parties may agree upon through an escrow 
established by the Parties.  At the closing, the Supplier shall execute and 
deliver to the Customer such bills of sale and instruments of assignment 
(including the assignment and assumption agreement referred to in clause (a) 
above) as are necessary or appropriate to transfer to the Customer all of the 
Supplier's right, title and interest in and to the Northwind Facilities and 
any contracts or Agreements to be assigned, on an "as is, where is" basis, 
without representation or warranty other than as to the Supplier's due 
authorization and legal capacity to execute and deliver such instruments, 
documents and Agreements, and the Customer shall deliver to the Supplier the 
purchase price, by wire transfer of immediately available funds or by other 
payment means acceptable to the Supplier, and shall execute and deliver such 
assignment and assumption agreement.

            (d)   In the event that the Customer exercises its option to 
purchase under this Section 9.3, effective upon closing of the purchase, this 
Agreement and the Lease shall automatically terminate.

            (e)   In the event that the Customer exercises the option granted 
by this Section 9.3 but shall fail to consummate the purchase pursuant to 
such option, such failure shall be a breach of the Customer's obligation to 
purchase the Northwind Facilities arising pursuant to exercise of such option 
and the Supplier shall be entitled to any remedies therefor which may be 
available at law or in equity.

      10.2  SUCCESSORS AND ASSIGNS.

            (a)   Neither party shall assign its interest or delegate its 
duties under this Agreement without the prior written consent of the other 
party, (which consent shall not be unreasonably withheld), except:

                  (i)   the Supplier may assign its right, title and interest 
under this Agreement, or any part thereof, to any wholly-owned subsidiary of 
Unicom Corporation;



                  (ii)  the Customer may assign its right, title and interest 
under this Agreement, or any part thereof, to any Affiliate, or to Music.  
Upon any such assignment by the Customer, the Supplier will provide any such 
assignee with all Notices given by the Supplier pursuant to this Agreement 
and such assignee (and its lenders) shall have the same respective rights to 
cure any failure by the Customer to comply with its obligations hereunder 
that the Customer and its lenders have hereunder.  In addition, if such 
assignee (or its lenders) assumes the Customer's rights and obligations 
hereunder, unconditionally and in a writing delivered to the Supplier, then, 
upon a request in writing from all such assignees stating that they desire 
the Supplier to sell some or all of the Services to third parties and 
specifying the portions of Services which they wish to have the Supplier sell 
to third parties and expressly and unconditionally committing to relinquish 
back to the Supplier such portions of the Services to effect such sale (the 
"Relinquished Services") as of a date specified in such request (but without 
any reduction in Contract Capacity Charges or Consumption Charges payable 
hereunder), and provided that such assignees pay all reasonable costs and 
expenses thereof, then the Supplier will use commercially reasonable efforts 
to sell any or all of the Relinquished Services to third parties on terms and 
conditions acceptable to such assignees, and any amounts which the Supplier 
receives from third parties in respect of Relinquished Services (if any) 
shall be applied to the Contract Capacity Charges and Consumption Charges 
payable hereunder (such application to be determined by the Supplier 
reasonably and in good faith and consistent with the concepts reflected in 
Exhibit C hereto and subject to such assignees' approval, not to be 
unreasonably withheld).

                  (iii) the Customer may assign its right, title and interest 
in this Agreement to any lender or lenders to whom the Customer provides a 
security interest in the Customer's right, title and interest in the Premises 
in connection with financing (or refinancing) the Premises; 

                  (iv)  the Customer may assign, without the Supplier's 
consent, the Customers's right, title and interest in this Agreement to any 
purchaser of the Premises or all of the interests in the Customer; and

                  (v)   the Supplier may assign its right, title and interest 
in this Agreement to any lender or lenders to whom the Supplier provides a 
security interest in the Supplier's right, title and interest in the 
Northwind Facilities in connection with financing (or refinancing) the 
Northwind Facilities.

In connection with any such financing or refinancing, from time to time, upon 
request, each party will provide one or more estoppel certificates in form 
and 



substance reasonably satisfactory to the other or such lender.  No consent by 
either party to any assignment or delegation by the other party shall be 
deemed to be a novation or otherwise to relieve the transferring party of its 
obligations hereunder unless otherwise expressly so stated in such consent.

            (b)   The Supplier agrees not to permit any transfer of any 
membership interest in the Supplier, and not to issue any new membership 
interests in the Supplier without the prior written consent of the Customer 
(such consent not to be unreasonably withheld); provided, however that the 
Customer hereby agrees to any such transfer or issuance to  Nevada Power 
Company (or any wholly-owned subsidiary of Nevada Power Company), Boston 
Edison, Ontario Hydro, Houston Industries, or to any entity which is 
beneficially owned  solely by Unicom Corporation and one of Nevada Power 
Company, Boston Edison, Ontario Hydro or Houston Industries (or any wholly 
owned subsidiary of Unicom Corporation); provided further that Unicom 
Corporation (or any wholly-owned subsidiary of Unicom Corporation) at all 
times holds at least a 51% share in the Supplier, unless such percentage 
requirement needs to be modified in order for Supplier to comply with Section 
5.7 hereof.

            (c)   This Agreement will be binding upon and inure to the 
benefit of the parties hereto and their successors and permitted assigns.  
Nothing in this Agreement, expressed or implied, is intended or will be 
construed to confer upon any Person (other than the parties and successors 
and assigns permitted by this Section 10.2 and Persons expressly benefitted 
by the provisions of Sections 8.1 and 8.2) any right, remedy or claim under 
or by reason of this Agreement.

      10.3  ENTIRE AGREEMENT; AMENDMENTS.  This Agreement, the Annex, the 
Exhibits and Schedules referred to herein, the Development Agreement, the 
Guaranty the Lease and the Energy Services Coordination Agreement and the 
documents delivered pursuant hereto and thereto contain the entire 
understanding of the parties hereto with regard to the subject matter 
contained herein or therein, and supersede all prior Agreements or 
understandings between or among any of the parties hereto.  This Agreement

instrument signed by an authorized representative of each of the parties 
hereto.

are inserted for convenience of reference only and are not intended to be a 
part of or to affect the meaning or interpretation of this Agreement.





      10.5  WAIVERS.  Any term or provision of this Agreement may be waived, 
or the time for its performance may be extended, by the party or parties 
entitled to the benefit thereof.  Any such waiver will be validly and 
sufficiently authorized for the purposes of this Agreement if, as to any 
party, it is authorized in writing by an authorized representative of such 
party.  The failure of any hereto to enforce at any time any provision of 
this Agreement will not be construed to be a waiver of such provision, nor in 
any way to affect the validity of this Agreement or any part hereof or the 
right of any party thereafter to enforce each and every such provision.  No 
waiver of any breach of this Agreement will be held to constitute a waiver of 
any other or subsequent breach.

      10.6  EXPENSES.  Except as otherwise set forth herein, each party 
hereto will pay all costs and expenses incident to its negotiation and 
preparation of this Agreement and to its performance and compliance with all 
Agreements and conditions contained herein on its part to be performed or 
complied with, including the fees, expenses and disbursements of its counsel 
and accountants.

      10.7  PARTIAL INVALIDITY.  Wherever possible, each provision hereof 
will be interpreted in such manner as to be effective and valid under 
applicable law, but in case any one or more of the provisions contained 
herein will, for any reason, be held to be invalid, illegal or unenforceable 
in any respect, such provision will be ineffective to the extent, but only to 
the extent, of such invalidity, illegality or unenforceability without 
invalidating the remainder of such invalid, illegal or unenforceable 
provision or provisions or any other provisions hereof, unless such a 
construction would be unreasonable.  Upon any such determination that any 
term or other provision hereof is invalid, illegal or unenforceable, the 
parties hereto shall negotiate in good faith to modify this Agreement so as 
to effect the original intent of the parties as closely as possible in an 
acceptable manner, to the end that the transactions contemplated hereby are 
fulfilled to the extent possible in the circumstances.

      10.8  EXECUTION IN COUNTERPARTS.  This Agreement may be executed in one 
or more counterparts, each of which will be considered an original 
instrument, but all of which will be considered one and the same agreement, 
and will become binding when one or more counterparts have been signed by 
each of the parties hereto and delivered to the Supplier and the Customer.

      10.9  GOVERNING LAW.  This Agreement will be governed by and construed 
in accordance with the internal laws and decisions of the State of Nevada.




      10.10 TIME.  Time is of the essence hereof.

      10.11 NO PARTNERSHIP.  This Agreement does not and shall not be 
construed to create or establish a partnership, agency, joint venture, lease, 
license or any other relationship between the parties hereto, nor constitute 
either party as an agent of the other.  Neither party hereto shall hold 
itself out to others, by act or omission, contrary to the terms of this 
Section 10.11.

      10.12 ARBITRATION.  In the event of any dispute hereunder between the 
parties, either party may at any time refer the dispute to be settled by 
binding arbitration pursuant to the Commercial Arbitration Rules of the 
American Arbitration Association.
