Osteologix Inc. Completes Reverse Merger Wednesday, May 24, 2006

SAN FRANCISCO, May 24 /PRNewswire/ -- Osteologix, Inc. a biopharmaceutical company headquartered in San Francisco, California, and with offices in Copenhagen, Denmark, announced today the completion of a reverse merger and share exchange transaction with publicly-held Castle & Morgan Holdings, Inc. based in New York, NY.

Concurrent with the merger, Osteologix also announced that it closed a $10 million private placement financing led by Rodman & Renshaw and Roth Capital Partners as placement agents. One of the key investors in this financing was Nordic Biotech which, until now, had been the sole investor in Osteologix. "We are very pleased with the interest and enthusiasm investors have shown in Osteologix," said Charles J. Casamento, President and CEO of Osteologix. "This additional capital should expedite the development of NB S101 and enable Osteologix to continue to further expand its pipeline and capabilities."

"This transaction should accelerate our company strategy of developing our innovative product, NB S101, for treatment of Osteoporosis and further enable negotiation and development of strategic collaborations and alliances," said Mr. Casamento "With our lead product NB S101 entering Phase II trials in the treatment of Osteoporosis, we have a solid platform for developing and commercializing drugs for bone disease and for women's health."

The transaction was completed by the exchange of newly issued shares of Castle & Morgan for shares held by the shareholders of Osteologix A/S of Copenhagen, Denmark and its subsidiary company, Osteologix, Inc. of San Francisco, California. Osteologix A/S remained the surviving corporation and as a result of the share exchange became a wholly-owned operating subsidiary of Castle & Morgan. In connection with the merger, Castle & Morgan's corporate name changed to Osteologix, Inc.

In consideration for their shares of Osteologix A/S, the Osteologix stockholders (including the investors in the $10 million private placement) collectively received approximately 87 percent of Castle & Morgan's shares on a fully-diluted basis after giving effect to the transaction. Further, the officers and directors of Osteologix replaced the officers and directors of Castle & Morgan. Castle & Morgan will cease all of its existing business operations and will immediately adopt and implement Osteologix's business plan.
