USM Capital Group, Inc. (UCGI), the financial services subsidiary of U.S. Microbics Inc. (OTCBB:BUGSE) announced today that its client, Majestic Safe-T-Products, LTD. (MSPL), has signed a Letter of Intent with ARS Networks, Inc. (OTCBB:ARSN) which will give MSPL shareholders 90% ownership of the common stock of ARSN after the transaction is completed.

Under the terms of the Letter of Intent, shareholders of MSPL will own 90% of the stock in ARSN after a 1 for 50 reverse split of ARSN stock. U.S. Microbics and USM Capital own approximately 27% of MSPL and estimate their combined holdings to be 5 MM shares after the transaction is complete. U.S. Microbics previously declared a dividend distribution of MSPL stock to BUGS shareholders of record as of August 30, 2002.

"We are delighted to convert our shareholdings of MSPL into restricted stock of a public company with a quoted market value and we believe that this transaction is in the best interest of BUGS shareholders and planned recipients of the MSPL dividend distribution," noted Robert C. Brehm, CEO of U.S. Microbics. "Once the transaction has been completed, BUGS will work with MSPL to determine the pro rata portion of ARSN stock to be distributed in place of MSPL stock to BUGS shareholders of record for August 30, 2002. The ARSN stock will be distributed after an SEC registration for the stock becomes effective. Based upon the current stock price of ARSN and a 1 for 50 reverse split, the dividend distribution is valued at approximately $600,000 and BUGS residual shareholdings are valued at $1,000,000."
