YDI Wireless and Terabeam Complete Merger

Falls Church, VA — June 22, 2004: Wireless systems providers YDI Wireless, Inc. (OTCBB: YDIW) and Terabeam Corporation today announced that they have completed their merger and Terabeam is now a wholly owned subsidiary of YDI.

At the meeting of Terabeam stockholders on June 21, 2004, the merger of YDI and Terabeam was approved by holders of approximately 98% of Terabeam’s shares that were voted on the proposal. The merger then became effective at 3:00 p.m. Eastern Time on June 22, 2004.

In the merger, each share of Terabeam’s common stock was converted into the right to receive 0.22 shares of YDI’s common stock (except for approximately 1.14 million shares of Terabeam stock the holders of which took the initial step to seek appraisal rights). Given the approximately 52.58 million shares of Terabeam stock outstanding prior to the merger, YDI expects to issue approximately 11.32 million shares of its stock to the former Terabeam stockholders (other than those who may seek appraisal rights). These shares will represent approximately 42.6% of YDI’s stock outstanding immediately after the transaction.

Also as part of the merger, YDI’s board of directors was revised to consist of four YDI designees and three Terabeam designees. The board members are now Daniel Saginario (Chairman), Robert Fitzgerald, Robert Wiedemer, and Michael Young (the four YDI designees) and John Gerdelman, Daniel Hesse, and Gary Rieschel (the three Terabeam designees).

Robert Fitzgerald, Chief Executive Officer of YDI, stated, “We are very pleased to have completed this transaction with Terabeam. I welcome Terabeam’s stockholders and thank them for their overwhelming support of the transaction. I also welcome Dan Hesse, John Gerdelman, and Gary Rieschel to our board of directors and look forward to working with them. Now, we will strive to achieve the contemplated benefits of this transaction and our recent acquisition of KarlNet and complete our transaction with Phazar.”
