Dear Customer:

We are pleased to share with you some exciting news that we believe will accelerate the growth of Thermage and offer increased revenue opportunities for your practice. As the enclosed press release outlines, today we announced that Thermage has entered into a definitive merger agreement to acquire Reliant Technologies Inc., a leader in skin resurfacing and rejuvenation with its Fraxel™ product line.

We’d like to share what this acquisition means for you.

We highly value our customers and believe that product innovation, safety, efficacy and helping you realize a return on your investment are all important factors in your decision to support an aesthetic company. At Thermage we continually strive to meet those expectations. The combination of Thermage’s leadership in skin tightening and contouring, and Reliant’s leadership in skin resurfacing and rejuvenation offers you an expanded and complementary product line, enabling you to offer a more complete solution to your clients.

Combining our resources will allow us to provide more comprehensive customer service and support, and the financial strength of the combined company will provide a foundation for innovation and development; enabling us to continue to develop compelling products to meet the demands of the growing aesthetic market.

The combined company will retain the Thermage name, and our executive offices will continue to be based in Hayward, California. We currently expect the proposed transaction to close during the fourth quarter of 2008, subject to customary closing conditions, including approval by Thermage stockholders. At this time, you should continue to contact your existing Thermage or Reliant representative for support. After we close the transaction, we expect to integrate the two sales organizations into one of the largest, most experienced sales teams in the aesthetic industry. We are confident that the combination of our sales and support resources will provide you with outstanding customer service.


We strongly believe that this combination will represent an excellent opportunity for both you and for Thermage. If you have any concerns or would like to share any feedback, please do not hesitate to contact me. Thank you for your continued support.

Regards,

Bill Brodie

Vice President of U.S. Sales
