adjustment to the Manufacturing Pricing shall be made. This may be more than one
quarter away from the present quarter, but is intended to be the present

comparison with the Old Exchange Rate, then Company and Buyer agree to adjust
the Manufacturing Pricing for the upcoming calendar quarter based on the
percentage change of the Current Exchange Rate as compared to the Old Exchange
Rate. Company agrees to send Buyer an updated price quotation reflecting the new
Manufacturing Pricing within three (5) business days of the 14th .

c. The only inputs to the Manufacturing Pricing formula that will be subject to
adjustment are the Labor Rate and Overhead factors. The Labor Rate will be
adjusted based on the percentage change of the Current Exchange Rate as compared
to the Old Exchange Rate. Any adjustments to the Manufacturing Pricing per the
provisions above shall be made based on the percentage change to the Old
Exchange Rate.

d. The Current Exchange Rate shall be defined by the following known resource:
www.oanda.com and shall be determined by calculating the daily exchange rate
average from the 14th day of the last month of the prior calendar quarter to the
14th day of the last month of the current calendar quarter.

e. Company and Buyer agree that in any applicable quarter, that the
Manufacturing Pricing may be adjusted either upwards or downwards based on the
increase or decrease in the currency value, as reflected in the Exchange Rate
comparison described above.

f. Any adjustments to the Manufacturing Pricing will only be made on a quarterly
basis in accordance with the procedures described above and will only impact
Products that are shipped in the new quarter. All Products that are delinquent
based on the original Company scheduled shipment date will not be impacted
