or ship the defective goods to High Voltage’s factory, Purchaser, at its own 
cost and expense, shall provide the facilities for such work as needed to 
inspect and evaluate and possibly repair/replace the goods. If inspection 
discloses that the defect is not one for which High Voltage is liable, then 
Purchaser shall promptly reimburse High Voltage for all expenses incurred. 

iii.

 

Upon receipt of the defective goods, or following access to the same, 

High Voltage shall inspect and evaluate the goods and determine the 
validity of Purchaser’s claim. 

iv.

 

The validity of any warranty claim, Purchaser’s compliance with the 

Limited Warranty and Limited Warranty Claim Procedure, and the 
obligation to replace, repair, or issue credit for any goods are solely and 
exclusively to be determined by High Voltage and any determination shall 
be final and binding.

RETURNS. 

No goods may be returned to High Voltage without High 

Voltage’s prior written permission, which permission may be withheld by 
High Voltage in its sole discretion. Any request for return authorization 
must be in writing and include, as applicable, model number, serial number, 
part number, reason for return, alleged defect, and apparent cause of alleged 
defect. Except as specifically provided in Section 9 Limited Warranty, if  
High Voltage consents to return of goods: (a) all return shipments are to be 
via prepaid freight and with all other charges prepaid, (b) if goods are 
returned to High Voltage within sixty (60) days from the date of original 
shipment for reasons other than an error by High Voltage in filling the 
Purchaser’s order, Purchaser shall only be entitled to receive a credit in an 
amount equal to the payment received by High Voltage for the goods minus 
(i) handling charges, and (ii) a restocking fee determined solely by High 
Voltage which shall not exceed twenty five percent (25%) of the invoiced 
amount, and (c) if goods are returned to High Voltage after sixty (60) days 
from the date of original shipment for reasons other than an error by High 
Voltage in filling the Purchaser’s order, Purchaser shall only be entitled to 
receive a credit in the amount equal to the payment received by High 
Voltage for the goods minus (x) a handling fee, and (y) a restocking fee in 
excess of twenty five percent (25%) which shall be determined by High 
Voltage.  

11.

 

SECURITY INTEREST.

  In order to induce High Voltage to ship 

goods without full payment, Purchaser grants a security interest to High 
Voltage in any and all of  Purchaser’s right, title and interest in the goods, 
and Purchaser agrees to comply with any reasonable request of High 
Voltage to perfect such security interest.  Purchaser hereby further 
authorizes High Voltage to perfect High Voltage’s security interest in said 
goods and consents to  filing  one or more financing statements without the 
signature of Purchaser. 

12.
