ITEM 1.01    ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

MESSRS. CLARK, BILTZ AND SLAVEN EMPLOYMENT AGREEMENT AMENDMENTS

             Effective as of June 20, 2005, SpectraSite, Inc. (the "Registrant")
amended its employment agreements with each of Stephen H. Clark, the
Registrant's Chief Executive Officer, Timothy G. Biltz, the Registrant's Chief
Operating Officer and Mark A. Slaven, the Registrant's Chief Financial Officer,
in order to comply with new Section 409A of the Internal Revenue Code, as added
by the American Jobs Creation Act of 2004. The amendments provide that if the
employment of any of Messrs. Clark, Biltz and Slaven is terminated in a manner
which entitles him to the payment of severance, the severance payments do not
commence until six months after the date of the termination, with the first
severance payment to include any severance installments deferred due to the
six-month delay (plus interest) and the remaining severance installments paid as
scheduled.

             In addition, in connection with the transactions contemplated by
that Agreement and Plan of Merger by and among the Registrant, American Tower
Corporation and Asteroid Merger Sub, LLC (the "Merger Agreement"), the
Registrant has amended its employment agreement with Mr. Slaven to provide for a
payment to Mr. Slaven of up to $2,056,000 to reimburse him (on a grossed-up
basis) for any "golden parachute" excise taxes (and any related interest or
penalties) to which he may become subject under Section 4999 of the Internal
Revenue Code in connection with a change of control of the Registrant. The
Registrant has also amended its employment agreement with Mr. Slaven to provide
for a reimbursement of up to $17,500 (plus an additional amount so that Mr.
Slaven retains $17,500 after payment of all income and employment taxes) for a
down payment on real estate that may be lost by him as a result of the
anticipated termination of his employment in connection with the Company's
upcoming merger into a subsidiary of American Tower Corporation (the "Merger").

             The foregoing description of the amendments to the Registrant's
employment agreements with each of Messrs. Clark, Biltz and Slaven does not
purport to be complete and is qualified in its entirety by reference to the
employment agreement amendments that are filed as Exhibits 10.1, 10.2 and 10.3
hereto and incorporated herein by reference.


MR. ALBERT STOCK OPTION AGREEMENT AMENDMENT

             Effective as of June 20, 2005, in connection with the transactions
contemplated by the Merger Agreement, the Registrant amended a Stock Option
Agreement entered into between the Registrant and outside director Paul M.
Albert, Jr. dated March 12, 2003 (the "Option Agreement") to provide that if Mr.
Albert is not selected to serve as a member of the Board of Directors of
American Tower Corporation upon and following the Merger, any unvested portion
of option represented by the Option Agreement shall become fully vested and
exercisable as of such date.

             The foregoing description of the amendment to Mr. Albert's Stock
Option Agreement does not purport to be complete and is qualified in its
entirety by reference to the amendment to Mr. Albert's Stock Option Agreement,
which is filed as Exhibit 10.4 hereto and incorporated herein by reference.
