ADDvantage Technologies Group, Inc. Expands Role with Scientific-Atlanta.

Business Editors

BROKEN ARROW, Okla.--(BUSINESS WIRE)--March 10, 2003

ADDvantage Technologies Group (OTCBB:ADDM) announced today that its subsidiary, Tulsat, is expanding its legacy products distribution program, by adding more product coverage under its existing exclusive agreement with Scientific-Atlanta.

Tulsat's legacy products program, initiated last year with Scientific-Atlanta, is unique in the industry. The program permits the manufacturer to maintain production efficiencies as volumes drop on maturing products, by producing a significant volume for Tulsat on a periodic basis. Customers benefit by having a convenient way to continue purchasing legacy products from a ready supply of inventory, rather than waiting on long lead times that often occur at the factory.

Initial products included in the program were Scientific-Atlanta's Prisma I Optics platform and its high-performance fixed-channel analog headend products. Such products include the industry classic 6350 modulator and its companion signal processor, as well as stereo encoding and demodulator products. Products now being added to the program include Scientific-Atlanta's flagship analog satellite receivers, agile modulators, stereo encoders and mid-market fixed-channel modulators.

"We are pleased that Scientific-Atlanta has decided to expand the legacy products program with us," commented Dave Chymiak, Chairman of the Board of ADDvantage Technologies Group. "This additional line coverage completes the transition of the legacy analog headend line which began last year, and further complements our expanding role as a master distributor and service center for Scientific-Atlanta."

ADDVANTAGE TECHNOLOGIES GROUP, INC. and its subsidiaries, TULSAT, LEE CATV Corporation, NCS Industries, Comtech Services, TULSAT-Texas, and TULSAT-Atlanta comprise an organization involved in the re-manufacture, repair and sale of previously owned cable television ("CATV") equipment and the distribution of new and surplus equipment to CATV operators for manufacturers such as Scientific-Atlanta and Motorola.
