Business Segments Description

Rental and Management

We conduct our site leasing business through our rental and management segment. Our primary business is leasing antenna space on multi-tenant communications sites to wireless service providers and radio and television broadcast companies. Our portfolio consists of towers that we own and towers that we operate pursuant to long-term lease arrangements, including approximately 20,000 tower sites in the United States and over 2,800 in Mexico and Brazil. In addition to these tower sites, we also offer access to over 10,000 rooftop and tower sites in the United States that we manage for third parties. Through our rental and management segment, we also operate in-building distributed antenna systems in malls and casino/hotel resorts.

Wireless Communications Towers. We are a leading owner and operator of wireless communications towers in the United States, Mexico and Brazil, based on number of towers and revenue. Our network in the United States includes approximately 19,200 wireless communications towers and spans 49 states and the District of Columbia. In addition, 87% of our U.S. network provides coverage in the top 100 markets or core areas such as high traffic interstate corridors. Our network in Mexico includes over 2,000 wireless communications towers in highly populated areas, including Mexico City, Monterrey, Guadalajara and Acapulco. Our network in Brazil consists of over 600 wireless communications towers, which are concentrated in southern Brazil in major metropolitan areas, including Sao Paulo, Rio de Janeiro, Brasilia and Curitiba.

Annual rental payments vary considerably depending upon:

• tower location;

• number and weight of antennas on the tower and the size of the transmission lines;

• ground space necessary to store customer’s electronic and other equipment related to the antennas;

• existing tower capacity;

• type of tower structure (e.g., stealth tower);

• placement of the customer’s antennas on the tower; and

• type and amount of frequency transmitted by the customer.

Broadcast Communications Towers. We are one of the largest independent owners and operators of broadcast towers in the United States and Mexico. We own approximately 200 broadcast towers in the United States and have exclusive rights to approximately 200 in Mexico. Broadcast towers generally are taller and structurally more complex than wireless communications towers, require unique engineering skills and are more costly to build. We lease antenna space on our broadcast towers primarily to radio and television broadcast companies. In leasing antenna space, we generally receive monthly fees from customers, with initial lease periods ranging from ten-to-twenty years.

In-Building Neutral Host Distributed Antenna Systems. We are a leading provider in the United States of in-building neutral host distributed antenna systems, with over 125 in-building systems in operation in retail shopping malls and casino/hotel resorts. We obtain rights to install and operate in-building systems by entering into leases with property owners, and we grant rights to wireless service providers to attach their equipment to our in-building system for a fee under licenses that typically have an initial non-cancelable term of at least ten years.

Network Development Services

We offer tower-related services through our network development services segment. We historically offered extensive tower-related services to support our site leasing business. During the last several years, as we continued to focus our operations on our rental and management segment, we sold services businesses that did not provide incremental value to our site leasing business. With the sale of our tower construction services unit in November 2004, we substantially completed our strategic transition to a focused site leasing company. Our network development services segment continues to provide site acquisition, zoning and permitting services and structural analysis services that support our site leasing operations and the addition of new tenants and equipment on our sites.

Site Acquisition, Zoning and Permitting Services. We engage in site acquisition services for our own account in connection with our tower development projects, as well as for our customers. We typically work with our customers’ engineers to determine the geographic areas where the customer needs to construct a new tower site to address its coverage objectives. Once a new site is identified, we acquire the rights to the land or structure on which the site will be constructed, and we manage the permitting process to ensure all necessary approvals are obtained to construct and operate the communications site under applicable law.
