SOLTA AND MEDICIS ANNOUNCE CLOSE OF AGREEMENT FOR LIPOSONIX^®

HAYWARD, Calif. and SCOTTSDALE, Ariz.—November 1, 2011— Solta Medical, Inc. (Solta) (NASDAQ:SLTM) and Medicis Pharmaceutical Corporation (Medicis) (NYSE:MRX) today announced that the two companies have closed their previously announced Stock Purchase Agreement for Solta to acquire all of the outstanding shares of Medicis Technologies Corporation (formerly LipoSonix, Inc.), a subsidiary of Medicis.

“The addition of LIPOSONIX^® adds another innovative technology to our market-leading portfolio of products,” said Stephen J. Fanning, Chairman, President and Chief Executive Officer of Solta. “High Intensity Focused Ultrasound (HIFU) represents a unique technology in the fat ablation market. We view this as a complementary technology to our existing Fraxel^® and Thermage^® offerings, creating additional cross-selling opportunities in our core customer base of leading plastic surgeons and dermatologists. We now have one of the strongest portfolios in the aesthetic space, with non-invasive, cutting-edge technologies in large and growing market segments – body contouring, skin tightening, skin resurfacing and rejuvenation, as well as acne reduction.”

“We are pleased to announce the close of this agreement with Solta,” said Jonah Shacknai, Chairman and Chief Executive Officer. “We believe Solta’s expertise in the aesthetic energy device market will serve the LIPOSONIX technologies well, as the worldwide market for fat ablation continues to be attractive. We are grateful to our employees for their commitment to the success of LIPOSONIX, and look forward to its continued success.”

Under the terms of the agreement, Solta paid to Medicis $15 million at closing, and will pay $20 million on or prior to November 19, 2011, as a result of achieving clearance in late October 2011 by the U.S. Food and Drug Administration (FDA) of the second generation LIPOSONIX system. Solta will also make certain additional future contingent payments based upon, among other things, the achievement of specified year-to-year increases in the worldwide commercial performance of the LIPOSONIX technologies. Solta’s obligation to make these additional future contingent payments expires after approximately 7 years. Additionally, Solta has assumed Medicis’ obligations to make future contingent payments under the acquisition agreement between Medicis and the former shareholders of LipoSonix, Inc.

The first generation LIPOSONIX system is currently marketed in Canada, the European Union and Japan. Medicis announced plans in February to explore strategic alternatives for the LIPOSONIX business, including, but not limited to, the sale of the stand-alone business, as Medicis focused on its core heritage of medical dermatology and facial aesthetics. The LIPOSONIX business was classified as a discontinued operation for financial statement reporting purposes beginning in the first quarter of 2011. Medicis anticipates providing updated guidance with its third quarter financial results announcement.

The Market

The LIPOSONIX treatment is not intended as a replacement for liposuction surgery or a healthy lifestyle, or a way to lose weight, but as a noninvasive, nonsurgical approach to aesthetic waist circumference reduction when diet and exercise are not enough. According to the American Society for Aesthetic Plastic Surgery (ASAPS), liposuction represented the second highest number of surgical cosmetic procedures in 2010 with over 280,000 procedures. This equates to a combined U.S. market of over $1.6 billion for liposuction and abdominoplasty.¹

About the LIPOSONIX System

The LIPOSONIX system technology was developed over a period of 10 years by leading scientists and ultrasound experts with more than 200 years of combined experience in the development of therapeutic and diagnostic ultrasound devices.

The LIPOSONIX system uses advanced high-intensity focused ultrasound (HIFU) technology to permanently destroy targeted fat just beneath the skin in the treatment areas of the abdomen and flanks as a noninvasive, nonsurgical approach to aesthetic waist circumference reduction. Clinical studies conducted by Medicis Technologies Corporation showed an average waist circumference reduction of approximately 2.6 cm after a single treatment with the LIPOSONIX system. Office visit time and individual results may vary. Results are typically seen in 8 to 12 weeks.

The LIPOSONIX treatment is not a replacement for liposuction surgery or a healthy lifestyle, or a way to lose weight. No special diet or exercise program is required. The LIPOSONIX system has a well-defined safety profile. There is no need for anesthesia.

Important Safety Information for the LIPOSONIX System

The LIPOSONIX treatment may pose certain risks and may not be suitable for everyone. The LIPOSONIX system is intended for adults over 18 years of age who have at least 1.0 cm of fat thickness beyond the selected treatment focal depth of the system in the area to be treated. The most frequently reported side effects during the LIPOSONIX treatment are: discomfort, pain, cold, prickling, tingling or warmth. The most frequently reported side effects after the LIPOSONIX treatment, when used as recommended, are: pain (discomfort), bruising, redness and swelling, which are generally described (or rated) as mild.
