DEVCON COMPLETES PURCHASE OF ADELPHIA COMMUNICATIONS CORPORATION

ELECTRONIC SECURITY SERVICES ASSETS

DEERFIELD BEACH, Fla., Mar. 1—Devcon International Corp. (NASDAQ: DEVC) today announced that, through Devcon Security Services Corp. (DSS), one of its indirect wholly owned subsidiaries, it completed the acquisition of certain net assets of the electronic security services operation of Adelphia Communications Corporation for $40.2 million in cash based substantially upon estimated contractually recurring monthly revenue of approximately $1.15 million.

The electronic security services operation assets acquired include a modern, full-service monitoring center located in Naples, Florida, from which more than 57,000 subscribers’ homes and businesses are monitored. The operation has sales and services offices in Boca Raton, Bonita Springs, Miami, Naples, Orlando and Tampa, Florida as well as in Buffalo, New York.

Ruzika, President of Devcon and DSS, said, “The acquisition of Adelphia’s security services operation makes DSS a leader in the Florida electronic security services market and will serve as our platform from which we will deliver customer focused security services to businesses, large and small, as well as to the ever-expanding residential market.”
