To: Mini-Circuits Customers:

We have been informed that China will announce the shutdown of all polluting factories for 9 weeks within a 200 kilometer radius of Beijing to clear the smog for the Olympics and Paralympics.

Many customers have inquired whether Mini-Circuits would be able to supply parts due to the impending shutdown of manufacturing facilities in China for 9 weeks within 200 km radius of Beijing prior to the Olympics.

Please be advised that Mini-Circuits has no suppliers in the vicinity of the proposed shutdown and consequently our ability to supply products to our customers will not be affected.

Please be assured of our continued commitment to providing excellent service to our customers.

With best regards,
Harvey Kaylie
President
