MELBOURNE, Australia, May 22 — QRSciences Holdings Limited, a leading developer of security technology products for governments and commercial clients worldwide with offices in Melbourne and San Diego, said today that it has agreed to acquire substantially all of the common shares of Diversified Opportunities, Inc, a US corporation whose shares trade on the Electronic Bulletin Board under the ticker symbol “DVOP.” Diversified Opportunities filed a 14F-1 notice with the United States Securities & Exchange Commission on May 19, 2008 to that effect. QRSciences shares trade on the Australian Stock Exchange under the ticker symbol “QRS,” and in the US as an ADR under the symbol “QRSNY.”

Kevin Russeth, Managing Director of QRSciences, said that the Company expects to merge into Diversified Opportunities certain of its proprietary technology assets. He said the Company believes that allowing its principal technology subsidiary to trade separately in the United States will be in the best interests of the shareholders, financial partners and customers.

The stock purchase agreement provides for the purchase by QRSciences of all Diversified Opportunities 9,000,000 shares of common stock, which shares represent approximately 98% of the 9,199,221 shares of common stock outstanding as of the date of the purchase agreement, in exchange for the payment of US$650,000.
