Advanced Biotherapy, Inc. (OTCBB:ADVB) announced today that it has closed the private placement of its 2002 Subordinated Convertible Pay-In-Kind Notes.

Mr. Edmond Buccellato, President and Chief Executive Officer, stated: "The placement of $500,000.00 of convertible notes on November 19, 2002 with an individual accredited investor, now places the Company's cash position at approximately $3.1 million as of November 27, 2002. As with our previous convertible debt and note offerings, the principal amount and related accrued interest is convertible to common stock at $0.25 per share. This most recently issued convertible note will bear interest at 12.5% per annum, payable semi-annually in cash or at the Company's option, in additional convertible notes. The note is due, unless converted to common stock prior to maturity, on June 1, 2006."

Mr. Buccellato further commented, "As indicated in our quarterly financial statements filed with the Securities and Exchange Commission on November 12, 2002, the Company had approximately $2.7 million in cash and short-term investments as of September 30, 2002. For the twelve-month period subsequent to September 30, 2002, the Company anticipates that its minimum cash requirements to continue as a going concern will be less than $1,500,000, and therefore, believes that it has adequate cash to maintain operations during that period."
