PURE Bioscience Raises $8.44 Million in Equity Financing

PURE Bioscience announced today that it has raised approximately $8.44 million in a private placement of its securities. After fees and expenses, the net proceeds to the Company were approximately $7.72 million.

Michael L. Krall, President and CEO of PURE Bioscience, stated, "We are extremely gratified by this vote of confidence by our investors. This capital raise represents another step on the road toward the listing of our stock on a national exchange. We have several sales and distribution agreements in process and look forward to 2008 being our breakout year."

The funds were raised through the sale of 1,677,596 unregistered securities units on October 19, 2007, solely to accredited investors, at $5.03 per unit. Each unit consisted of one share of PURE Bioscience common stock and one quarter of a five-year warrant to purchase PURE Bioscience common stock at $7.17 per share. A total of 419,394 such five-year warrants were issued to the investors. The purchase price per share represented an approximate 11% discount to the average closing bid price of the trailing ten days ending October 18, 2007. The aggregate of shares sold represents approximately 6.7% of the prior outstanding shares. A five-year warrant to purchase 167,776 shares of common stock at $8.60 per share was issued to Taglich Brothers, Inc. as the placement agent. The $7.72 million of net proceeds from the offering will be used for business development, research and development, working capital and other general corporate purposes.

The Company has agreed to file a registration statement with the Securities and Exchange Commission within ninety days of the closing for purposes of registering for resale the common stock issued and sold in the private placement and the shares underlying the warrants issued to both the investors and the placement agent.

With respect to the unregistered sales made, the Company relied on Regulation D and Section 4(2) of the Securities Act of 1933, as amended. No advertising or general solicitation was employed in offering the securities. The securities were offered to sophisticated, accredited investors who were provided all of the current public information available on the Company. This press release does not and will not constitute an offer to sell these securities and it is not soliciting an offer to buy these securities.
