Filed by SpectraSite, Inc. Pursuant to Rule 425 under the Securities Act of 1933 and Deemed Filed under Rule 14a-12 of the Securities Exchange Act of 1934 Subject Company: SpectraSite, Inc. Commission File No. 001-31769 FREQUENTLY ASKED QUESTIONS PLEASE NOTE THAT WE HAVE RECEIVED NUMEROUS INTEGRATION QUESTIONS CONCERNING ISSUES THAT WE ARE UNABLE TO ANSWER AT THIS TIME. MANY OF THEM WILL BE DECIDED UPON DURING THE MERGER INTEGRATION PROCESS OVER THE COMING MONTHS. ANSWERS TO THESE QUESTIONS WILL BE FORTHCOMING AT THE APPROPRIATE TIME AS THE INTEGRATION TEAMS CARRY OUT THEIR WORK. ANY OFFICIAL DECISIONS THAT ARE MADE WILL BE COMMUNICATED JOINTLY BY DALE CAREY (SPECTRASITE), AND STEVEN MOSKOWITZ (AMERICAN TOWER), AFTER THE INTEGRATION TEAM HAS APPROVED THEM. JUNE 20, 2005 1. Can the disclosure of American Tower current benefits plans, HR policies, etc. be available to SpectraSite employees for basic overview? Can Intranet access to these resources be granted to SpectraSite employees at this time? Until the closing of the merger, SpectraSite and American Tower must operate as separate entities and the current benefit programs offered by American Tower are subject to change as part of normal business practices. As part of the integration process, the human resources teams are analyzing the differences in the benefit programs and will make recommendations to the Steering Committee regarding benefits for the combined company following the closing. As you know, the Merger Agreement provides that SpectraSite employees retained following the closing of the merger will have the same or comparable benefits as they currently have for one year following the closing. 2. With respect to recent hiring activity, are we primarily filling positions that have been vacated, or are new positions being created? Are the new hires aware of the pending merger? It is "business as usual" and positions that have been vacated or budgeted will continue to be filled on an as needed basis. In addition, every new hire is being made aware of the pending merger as part of the hiring process. 3. With respect to the SpectraSite Severance Policy, where it states "[i]f an employee is asked to accept a position that requires him or her to accept a pay cut of 15% or more they can decline and receive severance," is such pay cut in terms of base pay or total pay (including bonus)? Base pay only. The Severance Policy states that a reasonable request for transfer includes lateral transfers and demotions where the employee's "base rate of pay" (excluding bonus) is impacted less than 15%. 4. If you are told that your position will not be eliminated in the first 90 days following closing but will be eliminated sometime after that, can you voluntarily leave the company after that 90 days but before you are officially "severed" and receive severance pay? No. If you voluntarily terminate your employment prior to the official termination date of your position, you would not be eligible for severance benefits. Please refer to the FAQ dated May 26, 2005, question no. 2 under "Severance." 5. Is there a requirement, or will an effort be made, for the new company to give XX days notice to the employee before severing him or her? The goal would be to provide as much advance notice as possible to employees who will not have a continuing position with the new company. This advance notice may vary based upon the specific department or position. 6. Why does Field Support Services have a hiring freeze, but other departments do not? There is no official hiring freeze for Field Support Services. At this time, there are some positions open in the West that SpectraSite management has decided to provide coverage for using existing resources and contractors. However, if the workload becomes such that this coverage plan is no longer effective, an alternative arrangement, which may include hiring additional resources, could be made.
