Gull Holdings Reaffirms Offer to Purchase Publicly-Held Shares of USANA Health

Sciences, Inc. at $26.00 per Share

Salt Lake City, UT, June 23, 2008—Gull Holdings, Ltd. and Unity Acquisition Corp. today reaffirmed their offer to purchase the outstanding shares of USANA Health Sciences, Inc. (NASDAQ: USNA) at $26.00 per share after USANA’s announcement of preliminary second quarter 2008 results and the filing by USANA with the SEC of an amended Solicitation/Recommendation Statement on Schedule 14D-9. USANA’s earnings guidance further solidifies Gull’s confidence that the financial conditions related to the previously arranged financing for the transaction will be satisfied. Gull noted that while the preliminary EPS announced remained lower than the year ago quarter, the preliminary net sales were slightly above the 2007 second quarter, and each represented an expected improvement over the first quarter of 2008.

Dr. Myron Wentz, Gull’s ultimate shareholder, said, “I am pleased to see the company’s revenue stabilize given the challenging business environment and the continuing third party allegations affecting public companies within the direct selling industry.”
