Zoom Technologies to Transfer to Nasdaq SmallCap Market
Transfer Scheduled for the Opening of Business on January 15, 2003

Boston, MA, January 14, 2003 — Zoom Telephonics, Inc. (NASDAQ: ZOOM) announced today that it will transfer the listing of its common stock to the Nasdaq SmallCap Market from the Nasdaq National Market at the opening of business on January 15, 2003. Zoom's stock will continue to trade under the symbol "ZOOM".

Zoom sought a transfer to the Nasdaq SmallCap Market because its common stock had not met Nasdaq's $1.00 per share minimum bid price requirement. A transfer to the Nasdaq SmallCap Market gives Zoom additional time to meet the Nasdaq minimum bid price requirement of $1.00 per share. By transferring to the Nasdaq SmallCap Market Zoom may be afforded an additional 180 day grace period in which to satisfy the minimum bid price requirement, potentially until July 20, 2003, provided that Zoom is able to continue to meet other applicable listing criteria, including shareholders' equity of at least $5 million. Furthermore, Zoom should be eligible to transfer back to the Nasdaq National Market if Zoom's bid price maintains the minimum $1.00 per share requirement for 30 consecutive trading days during the extended grace period and if Zoom has maintained compliance with all other continued listing requirements on the Nasdaq National Market. The Company's continued listing on the Nasdaq SmallCap Market is subject to its successful completion of an application and review process.

The Nasdaq SmallCap Market is fully automated, and provides real-time trade reporting and a marketplace for more than 800 companies. With the introduction of the Nasdaq SuperMontageSM trading system, securities listed on both the Nasdaq National Market and Nasdaq SmallCap Market share a unified, more liquid and transparent order entry system.
