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.
