Expected to be Accretive to Andrew Earnings Per Share in the First Full Year Following Completion

        ORLAND PARK, IL and BEACHWOOD, OH, FEBRUARY 18, 2003—Andrew Corporation (Nasdaq: ANDW) and Allen Telecom Inc. (NYSE: ALN) today announced the signing of a definitive agreement under which Andrew will acquire Allen in a stock-for-stock transaction valued at approximately $500 million. This strategically important and highly complementary combination establishes Andrew as the preeminent global wireless infrastructure subsystems supplier, with capabilities to provide total customer solutions, including virtually the entire base station RF footprint.

        With relationships with every major global OEM and operator, a product portfolio of unrivaled breadth, and local sales, manufacturing, and distribution presence in every major region of the world, Andrew is ideally positioned to support CDMA, TDMA and GSM wireless standards, as well as emerging 3G technologies.

        The combined company will be the number one global supplier of coaxial cables, RF power amplifiers, terrestrial microwave antennas, network geolocation solutions, and repeaters and in-building systems; and the number two global merchant provider of filters and base station antennas. Furthermore, the combined company can deliver an integrated offering of active components—filters and RF power amplifiers—to better meet the evolving performance and cost-efficiency requirements of customers.

        Andrew is now uniquely positioned in the telecommunications industry to generate both accelerated near-term growth from its expanded presence in these key market segments and to capture a greater portion of the $20 billion wireless infrastructure subsystems market.

        The transaction is expected to be accretive to Andrew earnings per share in the first full year following completion and will be structured to qualify as a tax-free exchange. The company sees substantial opportunities for synergies and cost savings—in excess of $40 million in annual cost savings following integration—from efficiencies in manufacturing, purchasing, research and development, and sales, general and administration.

        Under terms of the agreement, which has been unanimously approved by the Boards of Directors of both companies, Allen shareholders will receive 1.775 shares of newly-issued Andrew stock for each

Allen share that they currently own. Based on Andrew's closing price of $9.01 per share on February 14, 2003, the consideration represents a 21% premium over Allen's share price on the same day. Following completion of the transaction, on a fully diluted basis, excluding Allen preferred stock, Andrew shareholders will own approximately 64% and Allen shareholders will own approximately 36%.

        Following completion of the transaction, the combined company will have nearly 7,000 employees, pro forma annual revenues of approximately $1.3 billion, and annual R&D spending of $90 million. The company will also have a strong balance sheet and enhanced financial flexibility. Customers of the combined company will benefit tremendously from this unparalleled scale and financial strength.

        Ralph Faison, Chief Executive Officer and President of Andrew, said: "This is a landmark transaction that fundamentally redefines the dynamics of our industry. It extends Andrew's leadership in the wireless infrastructure subsystems market and positions us to lead the industry through its consolidation phase. The addition of Allen's strong presence in the attractive areas of filters, base station antennas, in-building systems and geolocation also diversifies and expands our product offerings, opening up new revenue streams and enabling us to provide customers with the most comprehensive product portfolio in the industry. We will also benefit greatly from the insights and experience of the talented Allen professionals joining our team."

        Robert G. Paul, President and Chief Executive Officer of Allen, said: "The strategic vision of this transaction is compelling. By joining forces with Andrew, we will gain access to new customers, who will benefit from our ability to offer them the most comprehensive solutions in the industry. Our shareholders receive a premium over the current value of their shares and the opportunity to benefit from the considerable upside we see for the combined company by virtue of their continuing investment."

        Dr. Floyd L. English, Chairman of Andrew, said: "Building on the success of our acquisition of Celiant, which greatly strengthened our position in power amplifiers, this transaction continues to advance our strategy of increasing our addressed markets through internal development initiatives and acquisitions, and significantly enhances our leadership position in the wireless infrastructure market."

        Philip Wm. Colburn, Chairman of Allen, and Robert G. Paul, Chief Executive Officer of Allen, will join the Andrew Board of Directors following completion of the transaction, increasing the total number of directors to 12.

        Completion of the transaction, which is expected to occur in the first half of 2003, is subject to approval of shareholders of both companies, expiration of the applicable waiting period under the Hart-Scott-Rodino Act and other customary closing conditions.

        Morgan Stanley acted as financial advisor to Andrew. Bear, Stearns & Co. Inc. acted as financial advisor to Allen.
