Item 2. Acquisition or Disposition of Assets

On November 12, 1999, Numerex Corp. (the "Corporation") sold the stock of its
wholly owned subsidiary, Bronzebase Limited, to British Telecommunications plc
("BT"). Bronzebase Limited is an English limited liability company which owns
all of the stock of Versus Technology Limited. The consideration for the sale
was 12,500,000 pounds (approximately U.S. $20,000,000), payable in cash at
closing. However, 750,000 pounds has been retained and placed in escrow pending
a post-closing net asset statement. The terms of the transaction were negotiated
between the Corporation and BT at arm's length. Numerex and BT also entered into
separate agreements which, among other things, allow Numerex to retain licensing
rights to market, sell and develop derived channel technology in certain
territories, principally the Americas.

This summary of the sale of Bronzebase Limited is qualified in its entirety by
reference to the terms of the Agreement Relating to the Sale and Purchase of the
Whole of the Issued Share Capital of Bronzebase Limited, which is filed as an
exhibit to, and incorporated by reference into this Form 8-K.

Item 5. Other Events.

Effective as of November 1, 1999, the Corporation and BellSouth Wireless, Inc.
("BellSouth") completed the previously reported restructuring of certain aspects
of their Cellemetry joint venture operating agreement. Cellemetry is 60% owned
by the Corporation and 40% owned by BellSouth.

Under the terms of the restructuring, the original operating agreement for
Cellemetry LLC, a Delaware limited liability company, has been modified and the
original Cellemetry business plan has been modified, revised and extended
through November 1, 2004. Greater flexibility has been created for third party
investment capital and performance tests and related rights have been reset to
November 2, 2002 in accordance with a modified business plan. The Corporation
has conveyed 100% of the capital stock of its formerly wholly owned subsidiary,
Uplink Security, Inc., a Georgia corporation, to Cellemetry. The Corporation has
also agreed to provide up to $5.5 million in debt financing to Cellemetry. In
addition, the Corporation issued preferred stock to BellSouth that is redeemable
or convertible to approximately 6% of the Corporation's common stock, and that
includes certain registration rights for the common stock upon such conversion.

This summary of the restructured operating agreement is qualified in its
entirety by reference to the terms of the Series A Preferred Stock Purchase
Agreement, First Amendment to the Operating Agreement, and Terms of Convertible
Preferred Stock, Series A, each of which is filed as an exhibit to, and
incorporated by reference into this Form 8-K.
