Department of Justice Closes Investigation of Metrocall/Arch Merger

     Alexandria, VA, Friday, November 5, 2004 – Metrocall Holdings, Inc. (NASDAQ: MTOH) today announced that it has been advised by the Anti-Trust Division of the United States Department of Justice that its investigation of the pending Metrocall/Arch merger has been closed. As a result, the related condition in the merger agreement has been satisfied. The merger continues to be subject to additional conditions, including the review and consent of the Federal Communications Commission and shareholder approval of both companies, both of which are pending, and the absence of appraisal demands by Metrocall shareholders exceeding 8% of the Metrocall common stock on a fully diluted basis, which, as previously announced, is not currently satisfied and may require waiver by the boards of directors of both companies.

     In addition, Metrocall also announced that the final tally for Metrocall shareholders electing cash in the cash election in the merger is 4,719,321 shares out of a total of 5,857,670 fully-diluted shares of Metrocall common stock eligible for election. In addition, one Metrocall shareholder that had asserted its appraisal rights gave notice to Metrocall prior to the 5:00 p.m. cash election deadline that it was revoking its appraisal exercise. After giving effect to that revocation, approximately 9.1% of the fully-diluted shares of Metrocall common stock have asserted appraisal rights to date. Exercises of appraisal rights may be made up to the time the vote is taken by Metrocall shareholders regarding the merger.
