[ALLEN TELECOM LOGO] ANDREW-ALLEN TRANSACTION Q&A - US-BASED ALLEN EMPLOYEE 401(K) BENEFITS JUNE 2003 Allen employees have been asking many questions about what changes will be made to the Allen Telecom Inc. employee benefit plans as a result of the impending merger with Andrew Corporation. Please note that all of your current benefits and policies will remain in effect immediately following the merger. A team of HR representatives from both Allen and Andrew are reviewing the current practices and will be making recommendations to senior management as to possible changes. Changes to benefits and policies will be communicated in advance allowing for transition time. The current Allen 401(k) plan recommendations are discussed below. For more information, please read the questions and answers below. Additional information will be provided as it becomes available. Q. WHAT WILL HAPPEN WITH THE ALLEN TELECOM INC. EMPLOYEE BEFORE-TAX SAVINGS PLAN (ALLEN'S 401(K) PLAN) AFTER THE OFFICIAL ANDREW-ALLEN MERGER DATE? A. Following the official merger date, the Allen 401(k) plan will continue to be administered by Charles Schwab. The Allen 401(k) plan will be continued except that employees will no longer have the ability to purchase Allen common stock through the plan because Allen common stock will cease to exist after the merger date. In lieu of Allen common stock, employees will have the opportunity to purchase Andrew common stock under the plan, although not at a discount. Q. SINCE THE ALLEN COMMON STOCK FUND WILL NO LONGER EXIST AFTER THE MERGER DATE, WHAT WILL HAPPEN TO THE EXISTING SHARES OF ALLEN COMMON STOCK THAT ARE IN MY 401(K) ACCOUNT? A. On the official merger date, any shares of Allen common stock that are in your Allen 401(k) plan account will be converted into shares of Andrew common stock. Your account will receive 1.775 shares of Andrew common stock for each share of Allen common stock currently held in your account. Q. IF I HAVE ELECTED TO PURCHASE ALLEN COMMON STOCK THROUGH THE ALLEN 401(K) PLAN, WHAT WILL HAPPEN WITH THE PERCENTAGE I HAVE ALLOCATED TO BUY ALLEN COMMON STOCK AFTER THE MERGER DATE? A. Since the Allen common stock fund will be converted into the Andrew common stock fund on the effective date of the merger, any percentage of your deferrals that you have allocated to the Allen common stock fund will be allocated to purchase shares of Andrew common stock in the Andrew common stock fund (please note that Andrew common stock will not be purchased at a discount). Q. IF I WANT TO MAKE CHANGES TO MY 401(K) INVESTMENT ALLOCATIONS, HOW CAN I DO SO? A. You can continue to make changes to your 401(k) allocations, either before or after the merger, by calling the SchwabPLAN hotline at 1-800-SCHPLAN or through www.schwabplan.com. Q. WILL THE ALLEN 401(K) PLAN CONTINUE TO EXIST AS IT IS TODAY FOR THE LONG TERM? A. No. The Allen 401(k) plan is expected to be combined with the Andrew 401(k) plan by the end of this calendar year. THIS DOCUMENT CONSTITUTES PART OF A PROSPECTUS COVERING SHARES OF ALLEN COMMON STOCK THAT HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THIS MEMORANDUM DOES NOT CONSTITUTE AN OFFER TO SELL OR A SOLICITATION OF ANY OFFER TO BUY THE ANDREW SECURITIES DESCRIBED IN THIS MEMORANDUM IN ANY STATE OR JURISDICTION TO ANY ENTITY OR PERSON TO WHOM IT IS UNLAWFUL TO MAKE SUCH AN OFFER OR SALE. Q. WHEN WILL MY 401(K) CONTRIBUTIONS NO LONGER GO INTO THE ALLEN 401(K) PLAN, BUT INSTEAD GO INTO THE ANDREW 401(K) PLAN? A. The 401(k) payroll deductions for October of 2003 will go into the Andrew 401(k) plan. The investment fund choices under the Andrew 401(k) plan are not the same as the investment fund choices under the Allen 401(k) plan. By the end of the 2003 calendar year, existing Allen 401(k) plan balances (including loans) are expected to be transferred into the Andrew 401(k) plan and investment fund choices. More details concerning investment fund choices under the Andrew 401(k) plan and the transfer will be forthcoming. Q. IF I AM EMPLOYED IN NORTHERN VIRGINIA AT EITHER COMSEARCH OR GRAYSON WIRELESS, WILL I GET MY PROFIT SHARING CONTRIBUTION FOR 2003? A. If you are employed at either Comsearch or the Reston, VA office of Grayson Wireless on September 30, 2003, you will get 75% of the 2003 profit sharing contribution into the Allen 401(k) plan. Thereafter, retirement benefits will be provided through Andrew's 401(k) plan. Q. WHEN WILL I FIND OUT MORE ABOUT THE ANDREW 401(K) PLAN? A. Employee on-site meetings about the Andrew 401(k) plan will be held in August and September of 2003. Q. AS A PARTICIPANT IN THE ALLEN 401(K) PLAN, WILL I HAVE A VOTE ON THE ANDREW-ALLEN MERGER? A. Yes, but only if you have Allen common stock as one of your investments. As a participant in the Allen 401(k) plan, you will be receiving materials being sent to all shareholders of Allen relating to the Special Meeting of Allen, which is scheduled to be held on July 15, 2003. To direct the Allen 401(k) plan trustee how to vote the shares of Allen common stock held in your account under the Allen 401(k) plan, simply mark your choices on the back of the Voting Instruction Card you will receive and return it in the postage-paid envelope so that it is received by the Allen 401(k) plan trustee no later than five days prior to the Special Meeting of Allen.
