     3.1 SCOPE OF DELIVERIES: The Contract Demand for deliveries under this 
Agreement is 7,500 kW. PacifiCorp shall deliver such amounts of Firm Power 
and Energy SUMMO requires to meet its load requirements up to, but not in 
excess of, such Contract Demand; PROVIDED, that if the Measured Demand 
exceeds the Contract Demand as a result of SUMMO's operations, the Measured 
Demand shall establish a new Contract Demand if PacifiCorp has capacity 
available adequate to supply such Demand on a firm basis. PacifiCorp shall 
notify SUMMO within sixty (60) days of the billing covering the period in 
which Measured Demand exceeded the Contract Demand whether such capacity is 
available. In such event, the new Contract Demand shall continue in effect 
until either (1) the new Demand is in turn exceeded by a Contract Demand, or 
(2) the eleventh billing

                                       2
<PAGE>

month following the billing month in which such Demand was established;
PROVIDED, in the latter event the Contract Demand shall then become the maximum
actual Measured Demand established in any of the preceding eleven (11) billing
months.

     3.2 REQUEST FOR ADDITIONAL CONTRACT DEMAND: Upon PacifiCorp's receipt of 
SUMMO's written request for additional power and energy, PacifiCorp shall 
attempt to supply such additional power and energy under terms and conditions 
acceptable to both parties. Within 15 days of the request PacifiCorp shall 
advise SUMMO in writing whether the additional power and energy is or can be

in excess of the Contract Demand commitments, such deliveries shall trigger a 
Contract Demand superseding the Contract Demand set forth in section 3.1.

     3.3 PAYMENT FOR AND COMMENCEMENT OF CONSTRUCTION: Within one (l) year of 
the date of this Agreement SUMMO expects to obtain all necessary permits and 
financing for its copper mining facilities in Lisbon Valley, Utah. Summo 
shall notify PacifiCorp when it obtains such permits and financing. If SUMMO 
provides such notice after December 24, 1996, PacifiCorp may recalculate the 
cost of the line extension and adjust the line extension payment and 
guaranteed minimum payments in a manner to compensate PacifiCorp fully for 
any decreased value of the dollar from the date of this Agreement to the date 
PacifiCorp receives such notice. Until it gives notice to PacifiCorp, 
SUMMO shall owe no financial obligation to PacifiCorp except the payment 
of $35,000 required upon execution of this Agreement pursuant to section 4.4. 
SUMMO shall make the first payment required under section 4.4 when it 
notifies PacifiCorp that it has obtained the necessary permits and financing. 
PacifiCorp shall complete construction of the facilities necessary to provide

     of reactive power between PacifiCorp's and SUMMO's system so as to 
     maintain a Power Factor of between ninety five percent (95%) lagging and 
     ninety percent (90%) leading at all times. If SUMMO's Power Factor 
     adversely affects operation of PacifiCorp's facilities or adversely 
     affects PacifiCorp's other customers, SUMMO shall install at SUMMO's 
     expense switched capacitors, synchronous condensers, or such other 
     devices and

                                       3
<PAGE>

     equipment as PacifiCorp may reasonably require to eliminate that portion
     of unscheduled reactive power flow which causes the Power Factor to 
     exceed the limits established herein. Should SUMMO fail to take
     corrective action requested by PacifiCorp within six (6) months after 
     written notice from PacifiCorp, PacifiCorp may perform such services or 
     supply and install such equipment as it deems necessary to provide 
     corrective action, whereupon SUMMO shall compensate PacifiCorp for all 
     sums expended and all services contracted or performed, including 
     PacifiCorp's standard overhead costs, plus ten percent (10%) of all 
     expenditures. SUMMO shall pay such sums within thirty (30) days after 
     PacifiCorp has mailed to SUMMO an itemized statement of its charges 
     therefor.

           3.6.2 ADJUSTMENT TO BILLING DEMAND: In the event SUMMO's Power 
     Factor drops below either 95% lagging or 90% leading, PacifiCorp's 
     Billing Demands shall be increased as specified for Power Factor that 
     drops below 90% lagging in Electric Service Schedule 9.

           3.6.3 HARMONICS: SUMMO shall operate its facilities on harmonic
     distortion within the guideline of the Agreement.

                     3.6.3. 1 The total harmonic voltage distortion (THD) 
          shall be less than five percent (5%), and the maximum individual 
          frequency voltage harmonic shall be less than three percent (3%) of 
          the fundamental. The voltage notch depth shall be less than twenty 
          percent (20%) and the notch area shall be less than 22,800 
          microseconds-volts.

                3.6.3.2 The total demand distortion (TDD) or harmonic current 
          distortion shall be less than eight percent (8%) of the maximum 
          demand load current. Individual odd current harmonics shall be less 
          than the following percentage of the fundamental (60 hertz) current.

                               3rd through 9th      7.0%
                               11th through 15th    3.5%
                               17th through 21st    2.5%
                               23rd through 35th    1.5%
                               35th and higher      0.5%

          Individual even harmonics shall be limited to twenty-five percent 
          (25%) of the odd harmonic limits specified above.

                 ELECTRIC SERVICE SCHEDULE NO. 9 - CONTINUED

     and action of Customer but are not the result of Customer's usual and 
     ordinary operations, shall be excluded from determination of new 
     Contract Demands. Upon prior arrangement with Company, Customer may 
     test, repair or start-up equipment at mutually acceptable and scheduled 
     off-peak periods and any demands in excess of the Contract Demand 
     established during such test, repair or start-up shall be excluded from 
     determination of new Contract Demands.

     FORCE MAJEURE: Neither Company or Customer shall be subject to any 
liability or damages for inability to provide or receive service to the 
extent that such failure shall be due to causes beyond the control of 
either Company or Customer, including, but not limited to the following: 
(a) the operation and effect of any rules, regulations and orders 
promulgated by any Commission, municipality, or governmental agency of 
the United States, or subdivision thereof; (b) restraining order, 
injunction or similar decree of any court; (c) war; (d) flood; (e) 
earthquake; (f) act of God; (g) sabotage; or (h) strikes or boycotts. 
Should any of the foregoing occur, the minimum billing demands that 
would otherwise be applicable under this Schedule shall be waived and 
Customer will have no liability for service until such time as Customer 
is able to resume service.

     The party claiming Force Majeure under this provision shall make 
every reasonable attempt to remedy the cause thereof as diligently and 
expeditiously as possible.

     Should Customer find it necessary to shut down operations because 
of market or economic conditions for a period of at least thirty (30) 
days, the 65% minimum billing demands that would otherwise be 
applicable under this Schedule shall be waived; provided, however, that 
in this event, 65% minimum billing demands shall not be waived for more 
than two (2) billing months in any contract year.

     TERMINATION: This provision does not apply to any Customers who 
contracted prior to July 29, 1982, for service except for those 
Customers whose Electric Service Agreements contain Contract Demand 
provisions with 65% minimum demand payment obligations. Termination of 
electric service by the Customer prior to the expiration date of the 
Electric Service Agreement (or any extension thereof) will not relieve 
the Customer of his obligations under this Rate Schedule and the 
Electric Service Agreement, including all 65% minimum payment 
obligations. In the event of termination, the 65% minimum payment 
amounts as stated herein, shall remain in full force and effect for the 
remaining unexpired term of the Electric Service Agreement; provided, 
however, that Company upon written request of Customer, shall attempt to 
sell Customer's Contract Demand obligations, or any portion thereof, to 
other parties and, upon such sale, Customer shall be relieved of the 
equivalent 65% minimum Contract Demand payment obligation. Company shall 
determine the priority of Customer's request to sell any Portion of its 
Contract Demand obligations by the date upon which Company receives 
Customer's written request. A sale is deemed to have occurred on the 
date Company executes an Electric Service Agreement for service with 
another party, and Customer, in order of priority, shall be relieved of 
its equivalent 65% minimum Contract Demand payment obligation as of that 
date.

     Termination prior to the expiration date of the Electric Service 
Agreement (or any extensions thereof) shall not relieve Customer of any 
non-contract demand minimum payment obligations incurred as a result of 
Company investments in special facilities
