      of the invoice. If the Buyer disputes part of an invoice but pays the
      undisputed portion of the invoice within ten (10) days of receipt of the
      invoice, then the Buyer will he entitled to a discount equal to [XX] per

of shipment of such equipment (“the Warranty”). For the 07 Transformer only, the
Warranty as it applies to oil leaks shall apply for a period of three (3) years,
but shall in all other respects apply for five (5) years. Notice of any claim
arising out of this Warranty shall be made in writing within the Warranty
period. Without limiting the. Buyer’s right to claim for all damages, losses,
expenses, and costs of whatever nature arising out of the Vendor’s breach of
this Agreement, if any Transformer supplied under this Agreement is deficient in
workmanship or material, the Vendor shall, at the sole option of the Buyer,
replace the Transformer or refund the Buyer the price paid for the Transformer.
Additionally, if a Transformer should fail within the Warranty Period then the
Vendor will pay to the Buyer the costs associated with labour and other
associated costs of removal and replacement of the failed unit to a maximum
actual cost of two thousand two hundred dollars ($2,200) per failure occurrence.
This Warranty shall survive the expiration or termination of this

from the Dedicated Inventory to the Buyer within forty-eight (48) hours of
receipt of notification from the Buyer, on an as needed basis.

     

    12.           Inspection

     

    All
Transformers will be subject to final inspection and approval by the Buyer after
delivery, and notwithstanding any prior payment. In the event that Transformers
are delivered which are not in conformity with the terms, conditions and
specifications of this Agreement, the Buyer may, at its option:

              (c)

            	
              repair/rework
      the delivered non-conforming goods or cause them to be repaired/reworked

      by the Buyer against amounts otherwise due the Vendor under this
      Agreement.

            


    

     

    13.           Termination

      Buyer may, for its convenience and at its sole option, terminate the

      stop performance of the Vendor’s services under the Agreement, except as
      may be necessary to carry out such termination and take any other action
      which the Buyer may reasonably direct. Without limiting the generality of

              The
      primary switch shall have a nominal continuous current rating of 200
      amperes. It shall be capable of withstanding a short-circuit current of
      25kA rms symmetrical for 2 seconds, and 40kA rms asymmetrical for 0.2
      seconds without causing any damage to contacts, leads, or other parts, or
      permitting sufficient heat to be generated which could seriously lower
      insulating value of the oil or generate gases to increase the pressure to
      dangerous levels.

    Upon the
placement of Toronto Hydro’s initial order of the transformer, the successful
Respondent(s) shall submit two (2) copies of a Certified Test Report reflecting
all production and type test results as outlined in this
specification.

     

    Certified
Test Reports shall include all the information as outlined in the attached
sample Test Report format (see Appendices Al & A2 to this

      deliver the transformer within the time scheduled for delivery as
      specified in the purchase order, it may be required to pay to Toronto
      Hydro a fee, up to a maximum of ten percent (10%) of the total purchase
      price, which will be deducted from the invoice. This fee will be deducted
      only if Toronto Hydro, as a result of the shipment delay, is required to
      construct and remove temporary facilities which may be required to meet
      the commitments of Toronto Hydro to provide electric
  power.

              In
      cases where the final average measured losses of identical units exceed
      the guaranteed values, the Toronto Hydro reserves the right to reject all
      of said units. If the Toronto Hydro should choose to accept these units,
      the successful Respondent(s) must reimburse the Toronto Hydro for the
      additional cost of the transformer losses, which will be deducted from the
      successful Respondent(s)’s invoice.

            


    

     

    
      	
               
      

            	
              In
      order to assess the value of non-guarantee, the average value of the
      measured no-load and full-load losses, taken from all of the identical
      units on order, will be used as the basis for the losses calculation. The
      cost. of losses will be calculated as
follows:

              If
      the no-load losses exceed the guarantee while the full-load losses are
      within the guarantee, the calculation for the cost of losses will be based
      on the following formula:

              If
      the no-load losses are within guarantee while the full-load losses exceed
      the guarantee, the calculation for the cost of losses will be based on the
      following formula:

      the guaranteed values, Toronto Hydro reserves the right to reject all of
      said units. If Toronto Hydro should choose to accept these units, the
      successful Respondent(s) must reimburse Toronto Hydro for the additional
      cost of the transformer losses, which will be deducted from the successful
      Respondent(s)’s invoice.

            


    

     

    
      	
               
      

            	
              In
      order to assess the value of non-guarantee, the average value of the
      measured no-load and full-load losses, taken from all of the identical
      units on order, will be used as the basis for the losses calculation. The
      cost of losses will be calculated as
follows:

            


    

     

    
      	
               
      

            	
              a)

            	
              If
      the no-load losses exceed the guarantee while the full-load losses are
      within the guarantee, the calculation for the cost of losses will be based
      on the following formula:

              b)

            	
              If
      the no-load losses are within guarantee while the full-load losses exceed
      the guarantee, the calculation for the cost of losses will be based on the
      following formula:

              c)

            	
              If
      both no-load and full-load losses exceed the guarantee, the calculation
      for the cost of losses will be based on formula
  (2).
