## CONSISTENT. PREDICTABLE. STABLE.
SBA COMMON STOCK IS LEADING OUR INDUSTRY AND OUTPERFORMING THE DOW, NASDAQ AND S&P 500 INDICES BY APPRECIATING 20% IN 2010.

In the future, when I think back to the year 2010 for SBA, I will remember a year of consistency, predictability, and stability. It was a year where we produced solid financial results every quarter, in each case slightly beating our own expectations and analysts' consensus estimates. A year where aggregate customer activity was steady, and similar to 2008 and 2009 levels of activity. A year where we achieved the high end of our portfolio growth goals without any single large acquisition, instead accomplishing our goals through a number of smaller transactions and new tower builds spread throughout the year. Consistent. Predictable. Stable. In all the consistency, however, there was no complacency. Management and our employees pushed hard all year long to constantly improve SBA, and as a result there was both material achievement and reward.

Achievement came in the form of firmly establishing SBA as an international company and attaining several financial milestones. We acquired or built towers in Costa Rica, El Salvador and Panama, and now have a base of operations in Central America with substantial human and operational resources. The towers we own internationally in Central America and Canada now represent 3% of our total tower portfolio, and we expect that percentage will grow in 2011. In the second half of 2010 we once again achieved our financial goal of 20% or greater year-over-year growth in equity free cash flow per share. In the fourth quarter we reached two financial milestones for SBA, our first $100 million adjusted EBITDA quarter and 80% tower cash flow margins, the highest ever publicly reported in our industry. Reward came in the form of stock price appreciation. Your SBA common stock in 2010 appreciated 20%, leading our industry and outperforming the Dow, NASDAQ and S&P 500 indices. We ended the year with our highest stock price per share since early 2001, and a gain over the five years ended December 31, 2010 of 129%.

How did we produce consistent, predictable and stable results, and achieve all of our goals while at the same time materially enhancing our company, positioning it well for the future and producing industry-leading rewards for our shareholders? Hard work, a very favorable environment for wireless demand, stable capital markets and a sharp focus on our long-time, three-part strategy for creating shareholder value: capture and maximize organic growth, achieve material portfolio growth and actively manage our balance sheet.

## ORGANIC GROWTH

Organic growth for SBA has always been a function of two things: the level of demand of our wireless carrier customers for additional network infrastructure, and the attractiveness and suitability of our assets and services offerings to those customers. As I mentioned earlier, in the United States and its territories wireless carrier activity in 2010 in the aggregate was steady and approximated 2008 and 2009 levels. In fact, in each of the three years from 2008 to 2010, our revenue added per tower was consistent and varied by less than 10% per year. Two nationwide carriers, AT&T and Verizon, were consistently busy all through 2010. AT&T's focus was on building additional 3G capacity and coverage, and also starting a 4G network. For Verizon, the focus was almost entirely on building a 4G network, which Verizon launched in certain markets in late 2010. Our other carrier customers in the U.S. had periods of activity in 2010 but were not consistently busy all year long with network development activities. In years past, these other carriers have been very busy with network development, and in certain periods were our most active customers. Does the fact that not all our customers were uniformly active in 2010 trouble me? No. To the contrary it gives me reason for optimism. Seldom in our 21 years in the network development business have all of our customers been uniformly busy. While the overall growth of wireless infrastructure has been secular, individual carrier capital spending has been cyclical based on each carrier's unique circumstances. Our customers have been busy enough in the aggregate to allow us to produce results ahead of our initial budgets and guidance, but never uniformly busy in any single year. Over multiple years, however, given the explosive growth in wireless (first voice, and now data), carriers have had to invest material amounts in their networks to satisfy consumer demands for new and improved service, and to remain competitive with their peers. This has been the trend for as long as we have been in business, and I believe the trend will continue indefinitely into the future.
There is ample evidence to support our belief around strong future carrier demand for additional network infrastructure and its impact on our organic growth. One source, Cisco, in its February 1, 2011 white paper, Global Mobile Data Traffic Forecast Update, 2010-2015, provides some startling and, for SBA, very positive observations and predictions for mobile wireless growth. In 2010, Cisco noted that the mobile data traffic growth rate was higher than anticipated and traffic nearly tripled for the third year in a row. Cisco projects global mobile data traffic will increase 26-fold between 2010 and 2015, growing at a compound annual growth rate of 92%. Mobile network connection speeds will increase ten-fold in the same period. Two-thirds of global mobile traffic will be video by 2015, with video being the most capacity and bandwidth-intensive form of data traffic. These forecasts, and others like them from a number of different sources, project significant growth in wireless over the next five years. To accommodate this growth, we believe material additional network infrastructure will be needed and as a result the organic growth prospects for SBA are very good.

IS SBA well-positioned to capture this organic growth? I believe the answer is clearly yes. Over the years we have worked very hard to assemble what we believe is the highest quality tower portfolio in the industry. We have been able to do this by building towers one at a time or by buying towers in many transactions small enough where we can review and underwrite the quality of each tower purchased. We select towers to build or buy mostly for their future lease-up potential. Our history has shown that we have made good choices with our portfolio, as our per tower revenue growth, per tower expense control and tower cash flow margin typically lead our industry. We believe the reasons why our tower portfolio has performed so successfully in the past will be the same reasons why we will capture our fair share (or more than our fair share) of the wireless infrastructure demand we expect will be so strong in the future. Our quality is similarly evident on the services, or site development, side of our business. In 2010, we

produced $91 million of services revenue, our highest since 2007, while satisfying the site development needs of our customers including all of the major U.S. wireless carriers. There are few site development firms in the U.S. with the history, experience, resources and capabilities of SBA. We believe our customers recognize those qualities and value them, and we are confident that we will continue as a preferred vendor for site development services.

## PORTFOLIO GROWTH

We had a good year in 2010 for portfolio growth. We added 836 towers to the portfolio, growing 9.5% on a net basis achieving our annual goal of 5% to 10% portfolio growth. Of the 836 towers we added, 567 were in the United States and its territories, and 269 were in international markets. It was business as usual for SBA in the U.S., and we broke new ground with our international activity. We have decided to expand into international markets for a number of reasons. First, the same underlying wireless demand drivers that have spurred U.S. network development (consumer penetration, data, smartphones, wireline substitution, etc.) are present globally. In many international markets, wireless is or will be the primary means of communication. Second, we understand the tower and network development business very well. We believe our domestic industry expertise can be carried to other markets. Third, in the international markets in which we are interested, there is zoning, regulation or other barriers to entry that make towers exclusive assets and not commodities. Fourth, by increasing our geographic scope, we believe we are increasing the odds of SBA achieving 5% to 10% portfolio growth each year. While we have accomplished our portfolio growth goals solely inside the U.S. in recent years, and we may still do so in 2011 and beyond, having a greater geographic reach will provide us with more investment opportunities to maximize return on investment. We believe we could enjoy materially higher returns on investment internationally, even after risk-adjusting the returns, given the much fewer number of independent tower owners, operators and developers outside the U.S.

We continue to be very active buying and building towers because of the demand drivers for additional wireless network development discussed above, both in the U.S. and internationally. We view portfolio growth as one of our core competencies, and typically favor it over other uses for our capital. Portfolio growth allows us to positively leverage our overhead, expand our adjusted EBITDA and adjusted EBITDA margin, increase our financeable asset base and add towers that we expect will produce favorable future organic growth. The more quality towers you own, the more absolute organic growth you will enjoy. We think we are pretty good at picking quality towers to build or buy that over time will achieve or exceed our revenue growth forecasts and return on capital requirements. We are very good at integrating new towers into our company smoothly and efficiently. So far our actual results have exceeded our forecasts. Each new asset investment, whether a tower build, tower acquisition or the purchase of land underlying our towers, must satisfy return on capital requirements that vary with our weighted average cost of capital and the perceived risk of the asset. I am pleased to say that this rigor has served us well, and our assets are producing returns ahead of plan.

## BALANCE SHEET MANAGEMENT

With respect to our balance sheet, we believe that through active management we can positively impact growth in equity free cash flow per share and increase shareholder value. We seek to maintain certain levels of net debt/annualized adjusted EBITDA leverage and interest coverage within what we consider to be an appropriate risk profile. Today, our liquidity position and balance sheet are strong. Thankfully, the capital markets returned to a favorable state in 2010 after rough periods in 2008 and 2009. In February 2010, we obtained a

$500 million credit facility. In April, we successfully completed a $1.23 billion Secured Tower Revenue Securities issue, refinancing all remaining 2011 debt maturities and extending future debt maturities. Our next maturity is now March 2013. Our credit facility, cash on hand and our expected cash flow from operations, provide us with more than enough capital to meet our portfolio growth goals for 2011. We continue to be thoughtful around capital structure and the ideal target leverage ratio. We continue to keep in the forefront of our thinking the capital markets crash of 2008, and the perceived and real impact it had on our ability to refinance. Our views on target leverage will change from time to time, and will depend on the amount of debt outstanding, our current and expected growth rate, overall market conditions and the general availability of credit, the timing and amount of our refinancing obligations, interest rates and whether the interest rate is floating or fixed for a period of time. We currently believe our position and prospects around all these items is sound.

Given our confidence around our capital structure and our goal to manage our capital structure for the long-term benefit of our shareholders, we increased our stock repurchase activity in 2010, repurchasing over $100 million of our common stock. We use stock repurchases opportunistically, when we believe our stock is undervalued, when we have ample liquidity and capacity within our target leverage ratio, and when there is no conflicting use for the funds to grow our asset portfolio.

## THE RESULT

The plan is working. 2010 was another good year for SBA and our shareholders. Our three-part strategy is working well and equity free cash flow per share is growing materially. Today, your company is in excellent shape. We continue to operate in the center of the fast-growing world of wireless, which will continue to provide us with many opportunities for growth for years to come. Our customers have needs for material additions and enhancements to their wireless networks, and they will call on us and others in our industry to address these needs. We have a sound capital structure with which to take advantage of growth opportunities. Our team is in place, and our employees continue to perform at the highest level of excellence and customer service. More than ever, we remain confident and optimistic about our prospects for creating additional value for our shareholders. As always, I want to thank our shareholders, customers and employees for their part in our success and we look forward to reporting our future results.

Sincerely,



Jeffrey A. Stoops
President & Chief Executive Officer

## ITEM 1. BUSINESS

## General

We are a leading independent owner and operator of wireless communications towers. Our principal operations are in the United States and its territories. In addition, we own towers in Canada, Costa Rica, El Salvador and Panama. Our primary business line is our site leasing business, which contributed 97.5% of our total segment operating profit for the year ended December 31, 2010. In our site leasing business, we lease antenna space primarily to wireless service providers on towers and other structures that we own, manage or lease from others. The towers that we own have been constructed by us at the request of a wireless service provider, built or constructed based on our own initiative or acquired. As of December 31, 2010, we owned 9,111 tower sites, the substantial majority of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. We also managed or leased approximately 5,300 actual or potential communications sites, approximately 500 of which were revenue producing as of December 31, 2010. Our other business line is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless service networks.

## Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under long-term lease contracts. Site leasing revenues are received primarily from wireless service provider tenants, including AT&T, Sprint, Verizon Wireless, and T-Mobile. Wireless service providers enter into numerous different tenant leases with us, each of which relates to the lease or use of space at an individual tower site. Tenant leases are generally for an initial term of five years with five 5-year renewal periods at the option of the tenant. These tenant leases typically contain specific rent escalators, which average 3% per year, including the renewal option periods.

In our new build program, we construct towers in locations that were strategically chosen by us or under build-to-suit arrangements. Under build-to-suit arrangements, we build towers for wireless service providers at locations that they have identified. We retain ownership of the tower and the exclusive right to co-locate additional tenants on the tower. When we construct towers in locations chosen by us, we utilize our knowledge of our customers' network requirements to identify locations where we believe multiple wireless service providers need, or will need, to locate antennas to meet capacity or service demands. We seek to identify attractive locations for new towers and complete pre-construction procedures necessary to secure the site concurrently with our leasing efforts. We generally will have at least one signed tenant lease for each new build tower on the day that it is completed and expect that some will have multiple tenants. During 2011, we intend to build at least 390 to 410 new towers, domestically and internationally.

In our tower acquisition program, we pursue towers that meet or exceed our internal guidelines regarding current and future potential returns. For each acquisition, we prepare various analyses that include projections of a five-year unlevered internal rate of return, review of available capacity, future lease up projections and a summary of current and future tenant/technology mix.



The table below provides information regarding the development and status of our tower sites portfolio over the past three years.

<table><tr><td rowspan="2"></td><td colspan="3">For the year ended December 31,</td></tr><tr><td>2008</td><td>2009</td><td>2010</td></tr><tr><td>Towers owned at beginning of period</td><td>6,220</td><td>7,854</td><td>8,324</td></tr><tr><td>Towers acquired (1)</td><td>1,560</td><td>376</td><td>712</td></tr><tr><td>Towers constructed</td><td>85</td><td>101</td><td>124</td></tr><tr><td>Towers reclassified/disposed of (2)</td><td>(11)</td><td>(7)</td><td>(49)</td></tr><tr><td>Towers owned at end of period</td><td>7,854</td><td>8,324</td><td>9,111</td></tr></table>

(1) 2008 includes 528 towers acquired in the Optasite acquisition, 423 towers acquired in the Tower Co. acquisition and 340 towers acquired in the Light Tower acquisition.

(2) Reclassifications reflect the combination for reporting purposes of multiple tower structures on a single parcel of real estate, which we market and customers view as a single location, into a single owned tower site. Dispositions reflect the decommissioning, sale, conveyance or other legal transfer of owned tower sites.

As of December 31, 2010, we had an average of 2.4 tenants per tower.

Our site leasing business generates substantially all of our total segment operating profit. Our site leasing business generated 85.4% of our total revenues during the year ended December 31, 2010 and has represented 97.4% or more of our total segment operating profit for the past three years. For the year ended December 31, 2010, site leasing revenues generated outside the U.S. and its territories was less than 1% of total revenue.

## Site Development Services

Our site development business is complementary to our site leasing business and provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation at our tower locations. Our site development business consists of two segments, site development consulting and site development construction. Site development services revenues are received primarily from providing a full range of end to end services to wireless service providers or companies providing development or project management services to wireless service providers. We principally perform services for third parties in our core historical areas of wireless expertise, specifically, site acquisition, zoning, technical services and construction.

In the consulting segment of our site development business, we offer clients the following range of services: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas; (4) support in buying or leasing of the location; and (5) assistance in obtaining zoning approvals and permits. In the construction segment of our site development business we provide a number of services, including, but not limited to the following: (1) tower and related site construction; (2) antenna installation; and (3) radio equipment installation, commissioning and maintenance. Personnel in our site development business also support our leasing and new tower build functions through an integrated plan across the divisions.

We provide our site development consulting and construction services on a local basis, through regional offices, territory offices and project offices. The regional offices are responsible for all site development operations, including hiring employees and opening or closing project offices, and a substantial portion of the sales in such area.

For financial information about our operating segments, please see Note 22 of our Consolidated Financial Statements included in this Form 10-K.



## Industry Overview

We believe that growing wireless traffic (particularly data and video), the successful spectrum auctions and technology developments will require wireless service providers to improve their network infrastructure and increase their network capacity resulting in an increase in the number of communication sites that they use or the number of antennas at existing communication sites. The following is a discussion of certain growth trends in the wireless communications industry:

- We believe that our customer's introduction and continued deployment of next generation wireless technologies including (i) 3G wireless services and (ii) long-term evolution and WiMAX (or “4G”), will require our customers to add a large number of additional cell sites and increase the amount of their equipment at current cell sites.

- The Federal Communications Commission's (the “FCC”) successful advanced wireless service spectrum auction 66 during 2006 for advanced broadband services and the FCC spectrum auction 73 during 2008 relating to the auction of the 700 MHz band, have provided existing carriers the opportunity to deploy spectrum for 3G and 4G wireless service which will further drive the demand for communication sites. For example, Leap Wireless and Metro PCS acquired spectrum in auction 66 in new coverage areas that have led and continue to lead to the launch of brand new networks while Clearwire is in the process of building out new markets as well. The current administration under President Barack Obama has made the release of additional wireless spectrum for commercial use in the U.S. a priority, and we believe that when such spectrum is released that it will drive additional demand for communication sites.

- Consumers continue to increase minutes of use, whether through wireline to wireless migration, increasing use of broadband services or simply talking more. Consumers are demanding quality wireless networks, and list network coverage and quality as two of the greatest contributors to their dissatisfaction when terminating or changing service. To decrease subscriber churn rate and drive revenue growth, wireless carriers have made substantial capital expenditures on wireless networks to improve service quality and expand coverage.

Despite the recent recessionary conditions affecting the global marketplace, based on these factors, we believe that the U.S. wireless industry will continue to grow and is well-capitalized, highly competitive and focused on quality and advanced services. Therefore, we expect that we will see a multi-year trend of strong additional cell site demand from our customers, which we believe will translate into strong leasing growth for us.

We believe that the international wireless markets in which we currently operate will continue to present growth opportunities for the wireless communications industry as these markets are anticipated to need new towers and communication sites. These markets also typically have limited, but quickly growing, wireline infrastructure and limited wireless data penetration. Further, some countries, such as Costa Rica, have recently had spectrum auctions that we expect will result in a meaningful build-out of new towers and communication sites. We intend to participate in such activity in these markets through buying or building towers, managing communication sites and leasing space to wireless service providers on assets we control.

## Business Strategy

Our primary strategy is to continue to focus on expanding our site leasing business due to its attractive characteristics such as long-term contracts, built-in rent escalators, high operating margins and low customer churn. The long-term nature of the revenue stream of our site leasing business makes it less volatile than our site development business, which is more cyclical. By focusing on our site leasing business, we believe that we can



maintain a stable, recurring cash flow stream and reduce our exposure to cyclical changes in customer spending. Key elements of our strategy include:

Maximizing Use of Tower Capacity. We generally have constructed or acquired towers that accommodate multiple tenants and a substantial majority of our towers are high capacity lattice or guyed towers. Most of our towers have significant capacity available for additional antennas and we believe that increased use of our towers can be achieved at a low incremental cost. We actively market space on our towers through our internal sales force.

Disciplined Growth of our Tower Portfolio. During 2011, we intend to grow our tower portfolio, domestically and internationally, by 5% to 10%. In connection with our international expansion, we have targeted international markets that we believe have relatively stable political environments and a growing wireless communication industry. We intend to use our available cash from operating activities and available liquidity, including borrowings, to build and/or acquire new towers at prices that we believe will be accretive to our shareholders both short and long term and which allow us to maintain our long-term target leverage ratios. Furthermore, we believe that our tower operations are highly scalable. Consequently, we believe that we are able to materially increase our tower portfolio without proportionately increasing selling, general and administrative expenses.

Capitalizing on our Scale and Management Experience. We are a large owner, operator and developer of tower and other communication sites, with substantial capital, human and operating resources. We have been developing communication sites for wireless service providers in the U.S. since 1989 and owned and operated tower sites for ourselves since 1997. We believe our size, experience, capabilities and resources make us a preferred partner for wireless service providers both in the U.S. and internationally. Our management team has extensive experience in site leasing and site development, with some of the longest tenures in the tower and site development industries. Management believes that its industry expertise and strong relationships with wireless service providers will allow us to expand our position as a leading provider of site leasing and site development services.

Controlling our Underlying Land Positions. We have purchased and intend to continue to purchase and/or enter into long-term leases for the land that underlies our towers, to the extent available at commercially reasonable prices. We believe that these purchases and/or long-term leases will increase our margins, improve our cash flow from operations and minimize our exposure to increases in ground lease rents in the future. As of December 31, 2010, we owned or controlled, for a minimum period of fifty years, land under 31.1% of our communication sites.

Using our Local Presence to Build Strong Relationships with Major Wireless Service Providers. Given the nature of towers as location specific communications facilities, we believe that substantially all of what we do is done best locally. Consequently, we have a broad field organization that allows us to develop and capitalize on our experience, expertise and relationships in each of our local markets which in turn enhances our customer relationships. We are seeking to replicate this expertise internationally. Due to our presence in local markets, we believe we are well positioned to capture additional site leasing business and new tower build opportunities in our markets and identify and participate in site development projects across our markets.

## Customers

Since commencing operations, we have performed site leasing and site development services for all of the large U.S. wireless service providers. In both our site development and site leasing businesses, we work with large national providers and smaller regional, local or private operators.



We depend on a relatively small number of customers for our site leasing and site development revenues. The following customers represented at least 10% of our total revenues during at least one of the last three years:

<table><tr><td rowspan="2"></td><td colspan="3">Percentage of Total Revenues</td></tr><tr><td colspan="3">For the year ended December 31,</td></tr><tr><td></td><td>2008</td><td>2009</td><td>2010</td></tr><tr><td>AT&amp;T (1)</td><td>23.1%</td><td>23.8%</td><td>23.9%</td></tr><tr><td>Sprint (2)</td><td>25.0%</td><td>21.9%</td><td>20.4%</td></tr><tr><td>Verizon Wireless (3)</td><td>15.6%</td><td>15.4%</td><td>14.8%</td></tr><tr><td>T-Mobile</td><td>11.2%</td><td>13.7%</td><td>11.6%</td></tr></table>

## Sales and Marketing

Our sales and marketing goals are to:

- use existing relationships and develop new relationships with wireless service providers to lease antenna space on and sell related services with respect to our owned or managed towers, enabling us to grow our site leasing business; and

- successfully bid and win those site development services contracts that will contribute to our operating margins and/or provide a financial or strategic benefit to our site leasing business.

We approach sales on a company-wide basis, involving many of our employees. We have a dedicated sales force that is supplemented by members of our executive management team. Our dedicated salespeople are based regionally as well as in the corporate office. We also rely on our regional vice presidents, general managers and other operations personnel to sell our services and cultivate customers. Our strategy is to delegate sales efforts to those employees of ours who have the best relationships with our customers. Most wireless service providers have national corporate headquarters with regional and local offices. We believe that wireless service providers make



most decisions for site development and site leasing services at the regional and local levels with input from their corporate headquarters. Our sales representatives work with wireless service provider representatives at the regional and local levels and at the national level when appropriate. Our sales staff compensation is heavily weighted to incentive-based goals and measurements.

Our primary marketing and sales support is centralized and directed from our headquarters office in Boca Raton, Florida and is supplemented by our regional and territory offices. We have a full-time staff dedicated to our marketing and sales efforts. The marketing and sales support staff is charged with implementing our marketing strategies, prospecting and producing sales presentation materials and proposals. In addition to our marketing and sales staff, we rely upon our executive and operations personnel at the regional and local office levels to identify sales opportunities within existing customer accounts.

## Competition

Site Leasing – Our primary competitors for our site leasing activities are (1) the national independent tower companies including American Tower Corporation, Crown Castle International and Global Tower Partners, (2) a large number of regional independent tower owners, (3) wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna space to other providers, and (4) alternative facilities such as rooftops, outdoor and indoor distributed antenna system (“DAS”) networks, billboards and electric transmission towers. There has been significant consolidation among the large independent tower companies in the past five years. Specifically, American Tower completed its merger with SpectraSite, Inc. in 2005, we completed our acquisition of AAT Communications Corporation in 2006 and Crown Castle completed its merger with Global Signal, Inc. in 2007. As a result of these consolidations, American Tower and Crown Castle have substantially more towers and greater financial resources than we do. Wireless service providers that own and operate their own tower networks are also generally larger and have greater financial resources than we do. We believe that tower location and capacity, quality of service to our tenants, and, to a lesser extent, price have been and will continue to be the most significant competitive factors affecting the site leasing business. Internationally, to date, the competition we have encountered has been from both independent tower companies and wireless service providers that own and operate their own tower networks. In our markets outside the U.S. and its territories, the majority of existing towers are owned by wireless service providers.

Site Development – The site development business is extremely competitive and price sensitive. We believe that the majority of our competitors in the U.S. site development business operate within local market areas exclusively, while some firms appear to offer their services nationally, including Bechtel Corporation, Black & Veatch Corporation, Goodman Networks, General Dynamics Corporation, Nsoro, and Wireless Facilities, Inc. The market includes participants from a variety of market segments offering individual, or combinations of, competing services. The field of competitors includes site development consultants, zoning consultants, real estate firms, right-of-way consulting firms, construction companies, tower owners/managers, radio frequency engineering consultants, telecommunications equipment vendors, which provide end-to-end site development services through multiple subcontractors, and wireless service providers' internal staff. We believe that providers base their decisions for site development services on a number of criteria, including: company experience, price, track record, local reputation, geographic reach and time for completion of a project. Currently, we do not offer site development services in markets outside of the U.S. and its territories.

## Employees

Our executive, corporate development, accounting, finance, human resources, legal and regulatory, information technology, site administration personnel, and our network operations center are located in our headquarters in Boca Raton, Florida. Certain sales, new tower build support and tower maintenance personnel are also located in our Boca Raton office. Our remaining employees are based in our regional and local offices.



As of December 31, 2010, we had 720 employees, none of whom are represented by a collective bargaining agreement. Of these 720 employees, 47 were based outside of the U.S. and its territories. We consider our employee relations to be good.

## Regulatory and Environmental Matters

Federal Regulations. Both the FCC and the Federal Aviation Administration (the “FAA”) regulate antenna towers and structures that support wireless communications and radio or television antennas. Many FAA requirements are implemented in FCC regulations. These regulations govern the construction, lighting and painting or other marking of towers and structures and may, depending on the characteristics of particular towers or structures, require prior approval and registration of towers or structures before they may be constructed, altered or used. Wireless communications equipment and radio or television stations operating on towers or structures are separately regulated and may require independent customer licensing depending upon the particular frequency or frequency band used. In addition, any applicant for an FCC antenna tower or structure registration must certify that, consistent with the Anti-Drug Abuse Act of 1988, neither the applicant nor its principals are subject to a denial of Federal benefits because of a conviction for the possession or distribution of a controlled substance.

Pursuant to the requirements of the Communications Act of 1934, as amended, the FCC, in conjunction with the FAA, has developed standards to consider proposals involving new or modified antenna towers or structures. These standards mandate that the FCC and the FAA consider the height of the proposed tower or structure, the relationship of the tower or structure to existing natural or man-made obstructions and the proximity of the tower or structure to runways and airports. Proposals to construct or to modify existing towers or structures above certain heights must be reviewed by the FAA to ensure the structure will not present a hazard to air navigation. The FAA may condition its issuance of a no-hazard determination upon compliance with specified lighting and/or painting requirements. Antenna towers that meet certain height and location criteria must also be registered with the FCC. A tower or structure that requires FAA clearance will not be registered by the FCC until it is cleared by the FAA. Upon registration, the FCC may also require special lighting and/or painting. Owners of wireless communications antenna towers and structures may have an obligation to maintain painting and lighting or other marking in conformance with FAA and FCC regulations. Antenna tower and structure owners and licensees that operate on those towers or structures also bear the responsibility of monitoring any lighting systems and notifying the FAA of any lighting outage or malfunction.

Owners and operators of antenna towers and structures may be subject to, and therefore must comply with, environmental laws. Any licensed radio facility on an antenna tower or structure is subject to environmental review pursuant to the National Environmental Policy Act of 1969, among other statutes, which requires federal agencies to evaluate the environmental impact of their decisions under certain circumstances. The FCC has issued regulations implementing the National Environmental Policy Act. These regulations place responsibility on applicants to investigate potential environmental effects of their operations and to disclose any potential significant effects on the environment in an environmental assessment prior to constructing or modifying an antenna tower or structure and prior to commencing certain operations of wireless communications or radio or television stations from the tower or structure. In the event the FCC determines the proposed structure or operation would have a significant environmental impact based on the standards the FCC has developed, the FCC would be required to prepare an environmental impact statement, which will be subject to public comment. This process could significantly delay the registration of a particular tower or structure.

We generally indemnify our customers against any failure to comply with applicable regulatory standards relating to the construction, modification, or placement of antenna towers or structures. Failure to comply with the applicable requirements may lead to civil penalties.



The Telecommunications Act of 1996 amended the Communications Act of 1934 by preserving state and local zoning authorities’ jurisdiction over the construction, modification and placement of towers. The law, however, limits local zoning authority by prohibiting any action that would discriminate among different providers of personal wireless services or ban altogether the construction, modification or placement of radio communication towers. Finally, the Telecommunications Act of 1996 requires the federal government to help licensees for wireless communications services gain access to preferred sites for their facilities. This may require that federal agencies and departments work directly with licensees to make federal property available for tower facilities.

As an owner and operator of real property, we are subject to certain environmental laws that impose strict, joint and several liability for the cleanup of on-site or off-site contamination and related personal or property damage. We are also subject to certain environmental laws that govern tower or structure placement, including pre-construction environmental studies. Operators of towers or structures must also take into consideration certain radio frequency (“RF”) emissions regulations that impose a variety of procedural and operating requirements. Certain proposals to operate wireless communications and radio or television stations from antenna towers and structures are also reviewed by the FCC to ensure compliance with requirements relating to human exposure to RF emissions. Exposure to high levels of RF energy can produce negative health effects. The potential connection between low-level RF energy and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. We believe that we are in substantial compliance with and we have no material liability under any applicable environmental laws. These costs of compliance with existing or future environmental laws and liability related thereto may have a material adverse effect on our prospects, financial condition or results of operations.

State and Local Regulations. Most states regulate certain aspects of real estate acquisition, leasing activities and construction activities. Where required, we conduct the site acquisition portions of our site development services business through licensed real estate brokers’ agents, who may be our employees or hired as independent contractors, and conduct the construction portions of our site development services through licensed contractors, who may be our employees or independent contractors. Local regulations include city and other local ordinances, zoning restrictions and restrictive covenants imposed by community developers. These regulations vary greatly from jurisdiction to jurisdiction, but typically require tower and structure owners to obtain approval from local officials or community standards organizations, or certain other entities prior to tower or structure construction and establish regulations regarding maintenance and removal of towers or structures. In addition, many local zoning authorities require tower and structure owners to post bonds or cash collateral to secure their removal obligations. Local zoning authorities generally have been unreceptive to construction of new antenna towers and structures in their communities because of the height and visibility of the towers or structures, and have, in some instances, instituted moratoria.

International. Regulatory regimes outside of the U.S. and its territories vary by country and locality, however, these regulations typically require tower owners and/or licensees to obtain approval from local officials, or government agencies prior to tower construction or the addition of a new antenna to an existing tower. Based on our experience to date, these regimes have been similar to, but not more rigorous, burdensome or comprehensive than those in the U.S. Our international operations are also subject to various regulations and guidelines regarding employee relations and other occupational health and safety matters. As we expand our operations into additional international geographic areas, we will be subject to regulations in these jurisdictions.

## Backlog

Backlog related to our site leasing business consists of lease agreements and amendments, which have been signed, but have not yet commenced. As of December 31, 2010, we had 253 new leases which had been executed with customers but which had not begun generating revenue. These leases will contractually provide for approximately $4.9 million of annual revenue. By comparison, as of December 31, 2009, we had 344 new leases



which had been executed with customers but which had not begun generating revenue. These leases contractually provided for approximately $7.6 million of annual revenue.

Our backlog for site development services consists of the value of work that has not yet been completed on executed contracts. As of December 31, 2010, we had approximately $17.8 million of contractually committed revenue as compared to approximately $13.9 million as of December 31, 2009.

## ITEM 1A. RISK FACTORS

## Risks Related to Our Business

If our wireless service provider customers combine their operations to a significant degree, our future operating results and our ability to service our indebtedness could be adversely affected.

Significant consolidation among our wireless service provider customers may result in our customers failing to renew existing leases for tower space or reducing future capital expenditures in the aggregate because their existing networks and expansion plans may overlap or be very similar. For example, in connection with the combinations of Verizon Wireless and ALLTEL (to form Verizon Wireless), Cingular and AT&T Wireless (to form AT&T Mobility) and Sprint PCS and Nextel (to form Sprint Nextel), the combined companies have rationalized and may continue to rationalize duplicative parts of their networks, which has led and may continue to lead to the non-renewal of certain leases on our towers. Furthermore, to the extent that other wireless service providers consolidate in the future, they may not renew any duplicative leases that they have on our towers and/or may not lease as much space on our towers in the future. If these consolidations significantly impact the number of tower leases that are not renewed or the number of new leases that the wireless service providers require to expand their network, our future operating results and our ability to service our indebtedness could be adversely affected.



We have a substantial level of indebtedness which may have an adverse effect on our business or limit our ability to take advantage of business, strategic or financing opportunities.

As indicated below, we have and will continue to have a significant amount of indebtedness relative to our equity. The following table sets forth our total principal amount of debt and shareholders' equity as of December 31, 2009 and 2010.

<table><tr><td rowspan="3"></td><td colspan="3">As of December 31,</td></tr><tr><td>2009</td><td>2010</td><td></td></tr><tr><td colspan="3">(in thousands)</td></tr><tr><td>Total principal amount of indebtedness</td><td>$ 2,771,012</td><td>$ 3,050,000</td><td></td></tr><tr><td>Shareholders&#x27; equity</td><td>$ 599,949</td><td>$ 317,110</td><td></td></tr></table>

Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay the principal, interest or other amounts when due. Subject to certain restrictions under our existing indebtedness, we and our subsidiaries may also incur significant additional indebtedness in the future, some of which may be secured debt. This may have the effect of increasing our total leverage.

As a consequence of our indebtedness, (1) demands on our cash resources may increase, (2) we are subject to restrictive covenants that further limit our financial and operating flexibility and (3) we may choose to institute self-imposed limits on our indebtedness based on certain considerations including market interest rates, our relative leverage and our strategic plans. For example, as a result of our substantial level of indebtedness and the uncertainties arising in the credit markets and the U.S. economy:

• we may be more vulnerable to general adverse economic and industry conditions;

- we may find it more difficult to obtain additional financing to fund future working capital, capital expenditures and other general corporate requirements that would be in our best long-term interests;

- we may be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and interest on our debt, reducing the available cash flow to fund other investments, including capital expenditures;

• we may, in the future, be required to reduce our annual tower acquisition and new build goals;

• we may have limited flexibility in planning for, or reacting to, changes in our business or in the industry;

- we may have a competitive disadvantage relative to other companies in our industry that are less leveraged; and

- we may be required to sell debt or equity securities or sell some of our core assets, possibly on unfavorable terms, in order to meet payment obligations.

These restrictions could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, mergers and acquisitions or other opportunities.

In addition, fluctuations in market interest rates may increase interest expense relating to our floating rate indebtedness, which we expect to incur under our 2010 Credit Facility and may make it difficult to refinance our existing indebtedness at a commercially reasonable rate or at all. There is no guarantee that the future refinancing



of our indebtedness will have fixed interest rates or that interest rates on such indebtedness will be equal to or lower than the rates on our current indebtedness.

We depend on a relatively small number of customers for most of our revenue, therefore if any of our significant customers reduced their demand for tower space or became financially unstable it may materially decrease our revenues.

We derive a significant portion of our revenue from a small number of customers. The loss of any one of our significant customers, as a result of bankruptcy, merger with other customers of ours or otherwise, could materially decrease our revenue and have an adverse effect on our growth.

The following is a list of significant customers (representing at least 10% of revenue in any of the last three years) and the percentage of our total revenues for the specified time periods derived from these customers:

Revenue from these clients is derived from numerous different site leasing contracts and site development contracts. Each site leasing contract relates to the lease of space at an individual tower site and is generally for an initial term of five years renewable for five 5-year periods at the option of the tenant. However, if any of our significant site leasing clients were to experience financial difficulty, substantially reduce their capital expenditures or reduce their dependence on leased tower space and fail to renew their leases with us, our revenues, future revenue growth and results of operations would be adversely affected.

Our site development customers engage us on a project-by-project basis, and a customer can generally terminate an assignment at any time without penalty. In addition, a customer’s need for site development services can decrease, and we may not be successful in establishing relationships with new customers. Furthermore, our existing customers may not continue to engage us for additional projects.



New technologies and their use by carriers may have a material adverse effect on our growth rate and results of operations.

The emergence of new technologies could reduce the demand for space on our towers. For example, the increased use by wireless service providers of signal combining and related technologies and products that allow two or more wireless service providers to provide services on different transmission frequencies using the same communications antenna and other facilities normally used by only one wireless service provider could reduce the demand for our tower space. Additionally, the use of technologies that enhance spectral capacity, such as beam forming or “smart antennae,” that can increase the range and capacity of an antenna could reduce the number of additional sites a wireless service provider needs to adequately serve a certain subscriber base and therefore reduce demand for our tower space. The development and growth of communications and other new technologies that do not require ground-based sites, such as the growth in delivery of video, voice and data services by satellites or other technologies, could also adversely affect the demand for our tower space. New technologies, including “small cell” technologies, that reduce the need for large antenna (or “macro configurations”) could reduce our customers need to lease space on our communication sites. Traditional macro-site installations currently are the source, and are expected to continue to be the source, of substantially all our site leasing revenue.

Our foreign operations are subject to economic, political and other risks that could materially and adversely affect our revenues or financial position, including risks associated with foreign currency exchange rates.

Our current business operations in Canada, Costa Rica, El Salvador and Panama and our expansion into any other international markets in the future, could result in adverse financial consequences and operational problems not typically experienced in the United States. Although the consolidated revenues generated by our international operations were immaterial during the year ended December 31, 2010, we anticipate that our revenues from our international operations may grow in the future. Accordingly, our business is and will in the future be subject to risks associated with doing business internationally, including:

• changes in a specific country’s or region’s political or economic conditions;

- laws and regulations that tax or otherwise restrict repatriation of earnings or other funds or otherwise limit distributions of capital;

- laws and regulations that dictate how we operate our communications sites and conduct business, including zoning and environmental matters;

• changes to existing or new tax laws directed specifically at the ownership and operation of tower sites;

• expropriation and governmental regulation restricting foreign ownership;

- the applicability of laws governing foreign operations including the Foreign Corrupt Practices Act and similar local anti-bribery laws;

- uncertainties regarding legal or judicial systems, including inconsistencies between and within laws, regulations and decrees, and judicial application thereof;

• health or similar issues, such as a pandemic or epidemic;

• difficulty in recruiting and retaining trained personnel; and

• language and cultural differences.



The majority of our international operations are denominated in United States dollars. However, for some of our international operations, we face risks associated with changes in foreign currency exchange rates, including those arising from our operations, investments and financing transactions related to our international business. Volatility in foreign currency exchange rates can also affect our ability to plan, forecast and budget for our international operations and expansion efforts.

Our convertible note hedge transactions may not cover all of the potential dilution or additional cash outlay, if we settled the notes in cash, to which we may be subject upon conversion of the notes.

Concurrently with the pricing of our 1.875% Convertible Senior Notes due 2013 (the “1.875% Notes”) and our 4.0% Convertible Senior Notes due 2014 (the “4.0% Notes”) we entered into convertible note hedge transactions and warrant transactions with affiliates of certain of the initial purchasers of the convertible note offerings. The initial strike price of the convertible note hedge transactions relating to our 1.875% Notes is $41.46 per share of our Class A common stock (the same as the initial conversion price of our 1.875% convertible notes) and the upper strike price of the warrants is $67.37 per share. The initial strike price of the convertible note hedge transactions relating to our 4.0% convertible Notes is $30.38 per share of our Class A common stock (the same as the initial conversion price of the 4.0% Notes) and the upper strike price of the warrant transactions is $44.64 per share.

Initially we entered into convertible note hedge and warrant transactions to cover the full amount of the shares that were issuable upon conversion of the 1.875% Notes and the 4.0% Notes. However, as a result of the global economic conditions in 2008, Lehman Brothers OTC Derivatives Inc. (“Lehman Derivatives”), a counterparty to one of the convertible note hedge transactions entered into in connection with our 1.875% Notes, filed a voluntary petition for protection under Chapter 11 of the United States Bankruptcy Code. As a result, on November 7, 2008, we terminated the convertible note hedge transaction with Lehman Derivatives which covered 55% of the 13,265,780 shares of our Class A common stock potentially issuable upon conversion of our 1.875% Notes. Consequently, we do not currently have a hedge with respect to those shares and, to the extent that the market price of our Class A common stock exceeds $41.46 per share upon conversion of the notes, we will be subject to dilution or if we settle in cash, additional costs, upon conversion of that portion of the 1.875% Notes. If any of the other counterparties to our convertible hedge transactions were to default in their obligations, then our potential dilution or costs upon conversion of the respective notes would be materially increased.

Pursuant to the terms of the warrant transaction, we are responsible for the dilution or costs, to the extent that we settle in cash or stock, arising from the conversion of the notes to the extent that the market price of our Class A common stock exceeds the strike price of the warrants. The strike price for the warrants covering 45% of the 1.875% Notes is $67.37 per share and the strike price for the warrants covering the 4.0% Notes is $44.64 per share. As of February 17, 2011, the closing sales price of our Class A common stock was $43.66 per share. If the market price of our Class A common stock significantly exceeded either of these strike prices on their respective conversion dates we would be subject to material dilution or, to the extent we elected to settle in cash, material additional costs.

Increasing competition may negatively impact our ability to grow our tower portfolio long-term.

We currently intend to grow our tower portfolio 5% to 10% annually, domestically and internationally, through acquisitions and new builds. Our ability to meet these growth targets significantly depends on our ability to acquire existing towers that meet our investment requirements. Traditionally, our acquisition strategy has focused on acquiring towers from smaller tower companies, independent tower developers and wireless service providers. However, as a result of consolidation in the tower industry there are fewer of these mid-sized tower transactions available and there is more competition to acquire existing towers. Increased competition for acquisitions may result in fewer acquisition opportunities for us, higher acquisition prices and increased difficulty.



in negotiating and consummating agreements to acquire such towers. Furthermore, to the extent that the tower acquisition opportunities are for significant tower portfolios, many of our competitors are significantly larger and have greater financial resources than us. If we are not able to successfully address these challenges, we may not be able to materially increase our tower portfolio in the long-term.

We currently intend to build at least 390 to 410 new towers, domestically and internationally, during 2011. However, our ability to build these new towers is dependent upon the availability of sufficient capital to fund construction, our ability to locate, and acquire at commercially reasonable prices, attractive locations for such towers and our ability to obtain the necessary zoning and permits. Furthermore, with respect to our international new builds, our tower construction may be delayed or halted as a result of local zoning restrictions, inconsistencies between laws or other barriers to construction in international markets.

Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by community developers, vary greatly, but typically require antenna tower and structure owners to obtain approval from local officials or community standards organizations prior to tower or structure construction or modification.

Due to these risks, it may take longer to complete our new tower builds than anticipated, the costs of constructing or acquiring these towers may be higher than we expect or we may not be able to add as many towers as we had planned in 2011. If we are not able to increase our tower portfolio as anticipated, it could negatively impact our ability to achieve our financial goals.

A slowdown in demand for wireless communications services or for tower space could materially and adversely affect our future growth and revenues.

If wireless service subscribers significantly reduce their minutes of use, or fail to widely adopt and use wireless data applications, our wireless service provider customers would experience a decrease in demand for their services. Regardless of consumer demand, each wireless service customer must have substantial capital resources and capabilities to build out their wireless networks. Two wireless carriers that currently own nationwide spectrum positions have announced the intention to build nationwide networks, but have also announced that they do not have all of the necessary financing in place to complete such networks. As a result of all of the above, wireless carriers may scale back their business plans or otherwise reduce their spending, which could materially and adversely affect demand for our tower space and our wireless communications services business, which could have a material adverse effect on our business, results of operations and financial condition.

In addition, other factors affecting the demand for our communication sites include:

- the impact of general economic conditions on consumers of wireless services;

- the impact of general economic conditions or regulatory policy on wireless service providers;

- the ability and willingness of wireless service providers to maintain or increase capital expenditures; and

• interest rates and the overall availability and cost of capital.

As a result of these factors, wireless service providers may delay or abandon implementation of new systems and technologies, including 3G, 4G or other wireless services or, worse, elect not to renew existing antenna leases in order to reduce operating expenses.



We may not secure as many site leasing tenants as planned or our lease rates for new tenant leases may decline.

If wireless service provider demand for tower space or our lease rates on new leases decreases, we may not be able to successfully grow our site leasing business as expected. This may have a material adverse effect on our strategy, revenue growth and our ability to satisfy our financial and other contractual obligations. Our plan for the growth of our site leasing business largely depends on our management’s expectations and assumptions concerning future tenant demand and potential lease rates for our towers.

Delays or changes in the deployment or adoption of new technologies or slowing consumer adoption rates may have a material adverse effect on our growth rate.

There can be no assurances that 3G, 4G or other new wireless technologies will be deployed or adopted as rapidly as projected or that these new technologies will be implemented in the manner anticipated. The deployment of 3G experienced delays from the original projected timelines of the wireless and broadcast industries, and deployment of 4G has been limited to date. Additionally, the demand by consumers and the adoption rate of consumers for these new technologies once deployed may be lower or slower than anticipated. These factors could have a material adverse effect on our growth rate since growth opportunities and demand for our tower space as a result of such new technologies may not be realized at the times or to the extent anticipated.

Our expansion initiatives may disrupt our operations or expose us to additional risk.

As we continue to acquire communications sites in our existing markets and expand into new markets, we are subject to a number of risks and uncertainties, including not meeting our return on investment criteria and financial objectives, increased costs, undisclosed and assumed liabilities and the diversion of managerial attention due to an acquisition. Acquisitions involve substantial operating and financial risks and no assurance can be given as to our future success in identifying, executing and integrating acquisitions. Our international expansion initiatives are subject to additional risks such as complex laws, regulations and business practices that may require additional resources and personnel, as well as those risks described above in “—Our foreign operations are subject to economic, political and other risks that could materially and adversely affect our revenues or financial position, including risks associated with foreign currency exchange rates.” Furthermore, we began expanding our operations internationally relatively recently, and the success of our international operations is subject to a number of uncertainties, including our ability to compete internationally with tower companies or wireless service providers that own and operate their own tower networks, that have been in the international market for a longer period of time. Although we generally focus our international efforts in countries with relatively stable political and macroeconomic environments, growing, competitive wireless communications industries and multiple wireless carriers that are likely to outsource their communications site infrastructure needs to us, we are subject to several factors outside of our control, and no assurance can be given that our expansion initiatives will succeed and not materially and adversely affect our business, results of operations and financial condition.

Increasing competition in the tower industry may create pricing pressures that may materially and adversely affect us.

Our industry is highly competitive, and our customers have numerous alternatives for leasing antenna space. Some of our competitors, such as (1) U.S. and international wireless carriers that allow collocation on their towers and (2) large independent tower companies, are substantially larger and have greater financial resources than us. This could provide them with advantages with respect to establishing favorable leasing terms with wireless service providers or in their ability to acquire available towers.

In the site leasing business, we compete with:



- wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna space to other providers;

• national and regional tower companies; and

- alternative facilities such as rooftops, outdoor and indoor DAS networks, billboards and electric transmission towers.

We believe that tower location and capacity, quality of service, density within a geographic market and, to a lesser extent, price historically have been and will continue to be the most significant competitive factors affecting the site leasing business. However, competitive pricing pressures for tenants on towers from these competitors could materially and adversely affect our lease rates. In addition, we may not be able to renew existing customer leases or enter into new customer leases, resulting in a material adverse impact on our results of operations and growth rate. Increasing competition could also make the acquisition of high quality tower assets more costly. Any of these factors could materially and adversely affect our business, results of operations or financial condition.

The site development segment of our industry is also extremely competitive. There are numerous large and small companies that offer one or more of the services offered by our site development business. As a result of this competition, margins in this segment continue to be under pressure. Many of our competitors have lower overhead expenses and therefore may be able to provide services at prices that we consider unprofitable. If margins in this segment were to further decrease, our consolidated revenues and our site development segment operating profit could be adversely affected.

If we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results.

Our real property interests relating to our towers consist primarily of leasehold and sub-leasehold interests, fee interests, easements, licenses and rights-of-way. From time to time, we experience disputes with landowners regarding the terms of ground agreements for the land under our towers, which can affect our ability to access and operate such towers. Further, landowners may not want to renew their ground agreements with us, they may lose their rights to the land, or they may transfer their land interests to third parties, including ground lease aggregators, which could affect our ability to renew ground agreements on commercially viable terms. Our inability to protect our rights to the land under our towers may have a future material adverse effect on our business, results of operations or financial condition.

In addition, we may not always have the ability to analyze and verify all information regarding title, access and other issues regarding the land underlying acquired towers. To the extent that we do not have complete access to, or use of, the land underlying the acquired towers, it could require us to incur additional expenses before we can operate and generate revenue from such tower.

Our debt instruments contain restrictive covenants that could adversely affect our business by limiting our flexibility.

Our 2010 Credit Facility contains certain restrictive covenants. Among other things, these covenants limit our ability to:

• incur indebtedness above a certain level;

• sell assets;



• make certain investments;

• engage in mergers or consolidations;

• incur liens; and

• enter into affiliate transactions.

These covenants could place us at a disadvantage compared to some of our competitors which may have fewer restrictive covenants and may not be required to operate under these restrictions. Further, these covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisitions or other opportunities. If we fail to comply with these covenants, it could result in an event of default under the 2010 Credit Facility. In addition, if we default in the payment of our other indebtedness, including under our 2010 Tower Securities and our notes, then such default could cause a cross-default under our 2010 Credit Facility.

The mortgage loan relating to our 2010 Tower Securities also contains financial covenants that require that the mortgage loan borrowers maintain, on a consolidated basis, a minimum debt service coverage ratio. To the extent that the debt service coverage ratio, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the debt service coverage ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. As lease payments from 3,683 tower sites of our total tower portfolio are pledged as collateral under the mortgage loan, if this cash flow was not available to us it could adversely impact our ability to pay our indebtedness, other than the mortgage loan, and to operate our business.

## Our dependence on our subsidiaries for cash flow may negatively affect our business.

We are a holding company with no business operations of our own. Our only significant asset is, and is expected to be, the outstanding capital stock and membership interests of our subsidiaries. We conduct, and expect to continue conducting, all of our business operations through our subsidiaries. Accordingly, our ability to pay our obligations is dependent upon dividends and other distributions from our subsidiaries to us. Most of our indebtedness is owed directly by our subsidiaries, including the mortgage loan underlying the 2010 Tower Securities, the 2016 Notes, the 2019 Notes and any amounts that we may borrow under the 2010 Credit Facility. Consequently, the first use of any cash flow from operations generated by such subsidiaries will be payments of interest and principal, if any, under their respective indebtedness. Other than the cash required to repay amounts due under our outstanding convertible notes, we currently expect that substantially all the earnings and cash flow of our subsidiaries will be retained and used by them in their operations, including servicing their respective debt obligations. The ability of our operating subsidiaries to pay dividends or transfer assets to us is restricted by applicable state law and contractual restrictions, including the terms of their outstanding debt instruments.



Our quarterly operating results for our site development services fluctuate and therefore we may not be able to adjust our cost structure on a timely basis with regard to such fluctuations.

The demand for our site development services fluctuates from quarter to quarter and should not be considered indicative of long-term results. Numerous factors cause these fluctuations, including:

- the timing and amount of our customers’ capital expenditures;

• the size and scope of our projects;

- the business practices of customers, such as deferring commitments on new projects until after the end of the calendar year or the customers’ fiscal year;

• delays relating to a project or tenant installation of equipment;

• seasonal factors, such as weather, vacation days and total business days in a quarter;

• the use of third party providers by our customers;

• the rate and volume of wireless service providers’ network development; and

• general economic conditions.

Although the demand for our site development services fluctuates, we incur significant fixed costs, such as maintaining a staff and office space in anticipation of future contracts. In addition, the timing of revenues is difficult to forecast because our sales cycle may be relatively long. Therefore, we may not be able to adjust our cost structure on a timely basis to respond to the fluctuations in demand for our site development services.

We are not profitable and expect to continue to incur losses.

We are not profitable. The following chart shows the net losses we incurred for the periods indicated:

<table><tr><td rowspan="3"></td><td colspan="4">For the year ended December 31,</td></tr><tr><td rowspan="2">2008</td><td colspan="2">2009</td><td>2010</td></tr><tr><td colspan="2">(in thousands)</td><td></td></tr><tr><td>Net loss</td><td>$ (67,164)</td><td>$ (141,119)</td><td>$ (194,421)</td><td></td></tr></table>

Our losses are principally due to depreciation, amortization and accretion expenses, interest expense (including non-cash interest expense and amortization of deferred financing fees), and losses from the extinguishment of debt as well as impairment charges on our towers in the periods presented above. We expect to continue to incur significant losses, which may affect our ability to service our indebtedness.

The loss of the services of certain of our key personnel or a significant number of our employees may negatively affect our business.

Our success depends to a significant extent upon performance and active participation of our key personnel. We cannot guarantee that we will be successful in retaining the services of these key personnel. We have employment agreements with Jeffrey A. Stoops, our President and Chief Executive Officer, Kurt L. Bagwell, our President - International, Thomas P. Hunt, our Senior Vice President, Chief Administrative Officer and General Counsel, and Brendan T. Cavanagh, our Senior Vice President and Chief Financial Officer. We do not have



employment agreements with any of our other key personnel. If we were to lose any key personnel, we may not be able to find an appropriate replacement on a timely basis and our results of operations could be negatively affected. Further, the loss of a significant number of employees or our inability to hire a sufficient number of qualified employees could have a material adverse effect on our business.

Our business is subject to government regulations and changes in current or future regulations could harm our business.

We are subject to federal, state and local regulation of our business, both in the U.S. and internationally. In the U.S., both the Federal Aviation Administration (“FAA”) and the FCC regulate the construction, modification and maintenance of antenna towers and structures that support wireless communications and radio and television antennas. In addition, the FCC separately licenses and regulates wireless communications equipment and television and radio stations operating from such towers and structures. FAA and FCC regulations govern construction, lighting, painting and marking of towers and structures and may, depending on the characteristics of the tower or structure, require registration of the tower or structure. Certain proposals to construct new towers or structures or to modify existing towers or structures are reviewed by the FAA to ensure that the tower or structure will not present a hazard to air navigation.

Antenna tower owners and antenna structure owners may have an obligation to mark or paint towers or structures or install lighting to conform to FAA and FCC regulations and to maintain such marking, painting and lighting. Antenna tower owners and antenna structure owners may also bear the responsibility of notifying the FAA of any lighting outages. Certain proposals to operate wireless communications and radio or television stations from antenna towers and structures are also reviewed by the FCC to ensure compliance with environmental impact requirements. Failure to comply with existing or future applicable requirements may lead to civil penalties or other liabilities and may subject us to significant indemnification liability to our customers against any such failure to comply. In addition, new regulations may impose additional costly burdens on us, which may affect our revenues and cause delays in our growth.

Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by community developers, vary greatly, but typically require antenna tower and structure owners to obtain approval from local officials or community standards organizations prior to tower or structure construction or modification. Local regulations can delay, prevent, or increase the cost of new construction, co-locations, or site upgrades, thereby limiting our ability to respond to customer demand. In addition, new regulations may be adopted that increase delays or result in additional costs to us. These factors could have a material adverse effect on our future growth and operations.

## Our towers are subject to damage from natural disasters.

Our towers are subject to risks associated with natural disasters such as tornadoes, hurricanes and earthquakes. We maintain insurance to cover the estimated cost of replacing damaged towers, but these insurance policies are subject to loss limits and deductibles. We also maintain third party liability insurance, subject to loss limits and deductibles, to protect us in the event of an accident involving a tower. A tower accident for which we are uninsured or underinsured, or damage to a significant number of our towers, could require us to incur significant expenditures and may have a material adverse effect on our operations or financial condition.

To the extent that we are not able to provide wireless services to our customers, due to a natural disaster or other catastrophic circumstances, our customers may not be obligated or willing to pay their lease expenses; however, we would be required to continue paying our fixed expenses related to the affected tower, including ground lease expenses. If we are unable to provide wireless services to our customers for a material portion of our towers, our operations could be materially and adversely affected.



We could have liability under environmental laws that could have a material adverse effect on our business, financial condition and results of operations.

Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal, state, local and foreign environmental and occupational safety and health laws and regulations, including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials, and wastes. As owner, lessee or operator of numerous tower sites, we may be liable for substantial costs of remediating soil and groundwater contaminated by hazardous materials, without regard to whether we, as the owner, lessee or operator, knew of or were responsible for the contamination. We may be subject to potentially significant fines or penalties if we fail to comply with any of these requirements. The current cost of complying with these laws is not material to our financial condition or results of operations. However, the requirements of these laws and regulations are complex, change frequently, and could become more stringent in the future. It is possible that these requirements will change or that liabilities will arise in the future in a manner that could have a material adverse effect on our business, financial condition and results of operations.

We have adopted anti-takeover provisions that could make it more difficult for a third party to acquire us.

Provisions of our articles of incorporation, our bylaws and Florida law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our shareholders. We adopted a shareholder rights agreement, which could make it considerably more difficult or costly for a person or group to acquire control of us in a transaction that our board of directors opposes. These provisions, alone or in combination with each other, may discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of our Class A common stock, or could limit the ability of our shareholders to approve transactions that they may deem to be in their best interests.

We could suffer adverse tax and other financial consequences if taxing authorities do not agree with our tax positions, or we are unable to utilize our net operating losses.

We are periodically subject to a number of tax examinations by taxing authorities in the states and countries where we do business. We also have significant deferred tax assets related to our net operating losses (“NOLs”) in U.S. federal and state taxing jurisdictions. Generally, for U.S. federal and state tax purposes, NOLs can be carried forward and used for up to twenty years, and all of our tax years will remain subject to examination until three years after our NOLs are used or expire. We expect that we will continue to be subject to tax examinations in the future. We recognize tax benefits of uncertain tax positions when we believe the positions are more likely than not of being sustained upon a challenge by the relevant tax authority. We believe our judgments in this area are reasonable and correct, but there is no guarantee that we will be successful if challenged by a tax authority. If there are tax benefits, including from our use of NOLs or other tax attributes, that are challenged successfully by a taxing authority, we may be required to pay additional taxes or we may seek to enter into settlements with the taxing authorities, which could require significant payments or otherwise have a material adverse effect on our business, results of operations and financial condition.

In addition, we may be limited in our ability to utilize our NOLs to offset future taxable income and thereby reduce our otherwise payable income taxes. We have substantial federal and state NOLs, including significant portions obtained through acquisitions and dispositions, as well as those generated through our historic business operations. In addition, we have disposed of some entities and restructured other entities in conjunction with financing transactions and other business activities.

To the extent we believe that a position with respect to an NOL is not more likely than not to be sustained, we do not record the related deferred tax asset. In addition, for NOLs that meet the recognition threshold, we assess



the recoverability of the NOL and establish a valuation allowance against the deferred tax asset related to the NOL if recoverability is questionable. Given the uncertainty surrounding the recoverability of certain of our NOLs, we have established a valuation allowance to offset the related deferred tax asset so as to reflect what we believe to be the recoverable portion of our NOLs.

Our ability to utilize our NOLs is also dependent, in part, upon us having sufficient future earnings to utilize our NOLs before they expire. If market conditions change materially and we determine that we will be unable to generate sufficient taxable income in the future to utilize our NOLs, we could be required to record an additional valuation allowance. We review our uncertain tax position and the valuation allowance for our NOLs periodically and make adjustments from time to time, which can result in an increase or decrease to the net deferred tax asset related to our NOLs. Our NOLs are also subject to review and potential disallowance upon audit by the taxing authorities of the jurisdictions where the NOLs were incurred, and future changes in tax laws or interpretations of such tax laws could limit materially our ability to utilize our NOLs. If we are unable to use our NOLs or use of our NOLs is limited, we may have to make significant payments or otherwise record charges or reduce our deferred tax assets, which could have a material adverse effect on our business, results of operations and financial condition.

Future sales of our Class A common stock in the public market or the issuance of other equity may cause dilution or adversely affect the market price of our Class A common stock and our ability to raise funds in new equity or equity-related offerings.

Sales of a substantial number of shares of our Class A common stock or other equity-related securities in the public market, including sales by any selling shareholder or conversion of the Notes, could depress the market price of our Class A common stock and impair our ability to raise capital through the sale of additional equity securities.

Our costs could increase and our revenues could decrease due to perceived health risks from radio frequency (“RF”) energy.

The U.S. government imposes requirements and other guidelines relating to exposure to RF energy. Exposure to high levels of RF energy can cause negative health effects. The potential connection between exposure to low levels of RF energy and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. According to the Federal Communications Commission (the “FCC”), the results of these studies to date have been inconclusive. However, public perception of possible health risks associated with cellular and other wireless communications media could slow the growth of wireless companies, which could in turn slow our growth. In particular, negative public perception of, and regulations regarding, health risks could cause a decrease in the demand for wireless communications services. Moreover, if a connection between exposure to low levels of RF energy and possible negative health effects, including cancer, were demonstrated, we could be subject to numerous claims. If we were subject to claims relating to exposure to RF energy, even if such claims were not ultimately found to have merit, our financial condition could be materially and adversely affected.

Our issuance of equity securities and other associated transactions may trigger a future ownership change which may negatively impact our ability to utilize net operating loss deferred tax assets in the future.

The issuance of equity securities and other associated transactions may increase the chance that we will have a future ownership change under Section 382 of the Internal Revenue Code of 1986. We may also have a future ownership change, outside of our control, caused by future equity transactions by our current shareholders. Depending on our market value at the time of such future ownership change, an ownership change under Section 382 could negatively impact our ability to utilize our net operating loss deferred tax assets in the event we generate future taxable income. Currently, we have recorded a full valuation allowance against our net operating



loss deferred tax asset because we have concluded that our loss history indicates that it is not “more likely than not” that such deferred tax assets will be realized.

## ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

## ITEM 2. PROPERTIES

We are headquartered in Boca Raton, Florida, where we currently lease approximately 73,000 square feet of office space. This lease expires February 28, 2022. We have entered into long-term leases for regional and certain site development office locations where we expect our activities to be longer-term. We open and close project offices from time to time in connection with our site development business. We believe our existing facilities are adequate for our current and planned levels of operations and that additional office space suited for our needs is reasonably available in the markets within which we operate.

Our interests in towers are comprised of a variety of fee interests, leasehold interests created by long-term lease agreements, perpetual easements, easements and licenses or rights-of-way granted by government entities. Of the 9,111 tower sites in our portfolio as of December 31, 2010, approximately 31.1% were located on parcels of land that we own, land subject to perpetual easements, or parcels of land that have a leasehold interest that extends beyond 50 years. In rural areas, a wireless communications site typically consists of up to a 10,000 square foot tract, which supports towers, equipment shelters and related equipment. Less than 2,500 square feet is required for a monopole or self-supporting tower structure of the kind typically used in metropolitan areas for wireless communications tower sites. Land leases generally have an initial term of five years with five or more additional automatic renewal periods of five years, for a total of thirty years or more.

## ITEM 3. LEGAL PROCEEDINGS

We are involved in various legal proceedings relating to claims arising in the ordinary course of business. We do not believe that the ultimate resolution of these matters will have a material adverse effect on our business, financial condition, results of operations or liquidity.

## ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with the information contained in our consolidated financial statements and the notes thereto. The following discussion includes forward-looking statements that involve certain risks and uncertainties, including, but not limited to, those described in Item 1A. Risk Factors. Our actual results may differ materially from those discussed below. See “Special Note Regarding Forward-Looking Statements” and Item 1A. Risk Factors.

We are a leading independent owner and operator of wireless communications towers. Our principal operations are in the United States and its territories. In addition, we own towers in Canada, Costa Rica, El Salvador and Panama. Our primary business line is our site leasing business, which contributed approximately 97.5% of our total segment operating profit for the year ended December 31, 2010. In our site leasing business, we lease antenna space to wireless service providers on towers and other structures that we own, manage or lease from others. The towers that we own have been constructed by us at the request of a wireless service provider, built or constructed based on our own initiative or acquired. As of December 31, 2010, we owned 9,111 tower sites, the substantial majority of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. As of December 31, 2010, we also managed or leased approximately 5,300 actual or potential communications sites, approximately 500 of which were revenue producing as of December 31, 2010. Our other business line is our site development business,



through which we assist wireless service providers in developing and maintaining their own wireless service networks.

## Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under long-term lease contracts. Site leasing revenues are received primarily from wireless service provider tenants, including AT&T, Sprint, Verizon Wireless and T-Mobile. Wireless service providers enter into numerous different tenant leases with us, each of which relates to the lease or use of space at an individual tower site. Tenant leases are generally for an initial term of five years with five 5-year renewal periods at the option of the tenant. These tenant leases typically contain specific rent escalators, which average 3% per year, including the renewal option periods. Tenant leases are generally paid on a monthly basis and revenue from site leasing is recorded monthly on a straight-line basis over the current term of the related lease agreements. Rental amounts received in advance are recorded in deferred revenue.

Cost of site leasing revenue primarily consists of:

• Rental payments on ground and other underlying property leases;

- Straight-line rent adjustment for the difference between rental payments made and the expense recorded as if the payments had been made evenly throughout the minimum lease term (which may include renewal terms) of the underlying property leases;

• Property taxes;

- Site maintenance and monitoring costs (exclusive of employee related costs);

• Utilities;

• Property insurance; and

• Deferred lease origination cost amortization.

For any given tower, such costs are relatively fixed over a monthly or an annual time period. As such, operating costs for owned towers do not generally increase significantly as a result of adding additional customers to the tower. The amount of other direct costs associated with operating a tower varies from site to site depending on the taxing jurisdiction and the height and age of the tower but typically do not make up a large percentage of total operating costs. The ongoing maintenance requirements are typically minimal and include replacing lighting systems, painting a tower or upgrading or repairing an access road or fencing. Lastly, ground leases are generally for an initial term of five years or more with multiple renewal terms of five year periods at our option and provide for rent escalators, which typically average 3% annually, or provide for term escalators of approximately 15%.



As indicated in the table below, our site leasing business generates substantially all of our total segment operating profit. For information regarding our operating segments, see Note 22 of our Consolidated Financial Statements included in this annual report.

(1) Site leasing segment operating profit and total segment operating profit are non-GAAP financial measures. We reconcile these measures and other Regulation G disclosures in this annual report in the section entitled Non-GAPP Financial Measures.

We believe that over the long-term, site leasing revenues will continue to grow as wireless service providers lease additional antenna space on our towers due to increasing minutes of network use, network expansion and network coverage requirements. We believe our site leasing business is characterized by stable and long-term recurring revenues, predictable operating costs and minimal non-discretionary capital expenditures. Due to the relatively young age and mix of our tower portfolio, we expect future expenditures required to maintain these towers to be minimal. Consequently, we expect to grow our cash flows by adding tenants to our towers at minimal incremental costs by using existing tower capacity or requiring wireless service providers to bear all or a portion of the cost of tower modifications. Furthermore, because our towers are strategically positioned and our customers typically do not relocate, we have historically experienced low tenant lease terminations as a percentage of revenue.

## Site Development Services

Our site development services business is complementary to our site leasing business and provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation at our tower locations. Our site development services business consists of two segments, site development consulting and site development construction. Site development services revenues are received primarily from providing a full range of end to end services to wireless service providers or companies providing development or project management services to wireless service providers. We principally perform services for third parties in our core, historical areas of wireless expertise, specifically, site acquisition zoning, technical services and construction.



Our site development customers engage us on a project-by-project basis and a customer can generally terminate an assignment at any time without penalty. Site development projects, both consulting and construction, include contracts on a time and materials basis or a fixed price basis. The majority of our site development services are billed on a fixed price basis. Time and materials based site development contracts are billed and revenue is recognized at contractual rates as the services are rendered. Our site development projects generally take from three to twelve months to complete. For those site development consulting contracts in which we perform work on a fixed price basis, we recognize revenue based on the completion of agreed upon phases of the project on a per site basis.

Our revenue from site development construction contracts is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. Revenue from our site development construction business may fluctuate from period to period depending on construction activities, which are a function of the timing and amount of our clients’ capital expenditures, the number and significance of active customer engagements during a period, weather and other factors.

Cost of site development consulting revenue and construction revenue includes all costs of materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly related to the projects. All costs related to site development consulting contracts and construction contracts are recognized as incurred.

The table below provides the percentage of total company revenues contributed by site development services over the last three years. For information regarding our operating segments, see Note 22 of our Consolidated Financial Statements included in this annual report.

## International Operations

As of December 31, 2010, we had operations in Canada, Costa Rica, El Salvador and Panama. Our operations in these four countries are solely in the site leasing business, and we expect to expand operations through new builds and acquisitions. Tenant leases and ground leases in these international markets typically have similar terms and conditions as those in the United States, with a fixed initial term of three to five years, and specific rent escalators.

In our Central American markets, significantly all of our revenue, expenses, and capital expenditures arising from our new build activities are denominated in U.S. dollars. Specifically, our ground leases, our tenant leases and most of our tower related expenses are due, and paid, in U.S. dollars. In our Canadian operations, significantly all of our revenue, expenses and capital expenditures arising from our new build activities, including



tenant leases, ground leases and other tower-related expenses, are denominated in Canadian dollars. In each of these markets our local currency obligations are principally limited to (1) salaries and other employee benefits, (2) permitting and other local fees, (3) utilities and (4) taxes; however, in some of our Central American markets, a portion of these expenses may also be paid in U.S. dollars.

## Critical Accounting Policies and Estimates

We have identified the policies and significant estimation processes below as critical to our business operations and the understanding of our results of operations. The listing is not intended to be a comprehensive list. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States, with no need for management’s judgment in their application. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. The impact and any associated risks related to these policies on our business operations is discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations” where such policies affect reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see Note 2 of our Consolidated Financial Statements for the year ended December 31, 2010, included herein. Our preparation of our financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities at the date of our financial statements, and the reported amounts of revenue and expenses during the reporting periods. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. There can be no assurance that actual results will not differ from those estimates and such differences could be significant.

## Construction Revenue

Revenue from construction projects is recognized using the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because we consider total cost to be the best available measure of progress on each contract. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on each contract nears completion. The asset “Costs and estimated earnings in excess of billings on uncompleted contracts” represents expenses incurred and revenues recognized in excess of amounts billed. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized.

## Allowance for Doubtful Accounts

We perform periodic credit evaluations of our customers. We continuously monitor collections and payments from our customers and maintain an allowance for estimated credit losses based upon our historical experience and any specific customer collection issues that we have identified. Establishing reserves against specific accounts receivable and the overall adequacy of our allowance is a matter of judgment.

## Asset Impairment

We evaluate the potential impairment of individual long-lived assets, principally the tower sites. We record an impairment charge when we believe an investment in towers or intangible assets has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower site. We consider many factors and make certain assumptions when making this assessment, including but not limited to: general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In addition, we make certain assumptions in determining an asset’s fair value for purposes of calculating the amount of an impairment charge. Changes in those assumptions or market conditions may result in a fair value which is different from management’s estimates. Future adverse changes in



market conditions could result in losses or an inability to recover the carrying value, thereby possibly requiring an impairment charge in the future. In addition, if our assumptions regarding future undiscounted cash flows and related assumptions are incorrect, a future impairment charge may be required.

## Property Tax Expense

We typically receive notifications and invoices in arrears for property taxes associated with the tangible personal property and real property used in our site leasing business. As a result, we recognize property tax expense, which is reflected as a component of site leasing cost of revenue, based on our best estimate of anticipated property tax payments related to the current period. We consider several factors in establishing this estimate, including our historical level of incurred property taxes, the location of the property, our awareness of jurisdictional property value assessment methods and industry related property tax information. If our estimates regarding anticipated property tax expenses are incorrect, a future increase or decrease in site leasing cost of revenue may be required.

## KEY PERFORMANCE INDICATORS

## Non-GAAP Financial Measures

This report contains certain non-GAAP measures, including Segment Operating Profit and Adjusted EBITDA information. We have provided below a description of such non-GAAP measures, a reconciliation of such non-GAAP measures to their most directly comparable GAAP measures and an explanation as to why management utilizes these measures.

## Segment Operating Profit:

We believe that Segment Operating Profit is an indicator of the operating performance of our site leasing and site development segments and is used to provide management with the ability to monitor the operating results and margin of each segment, while excluding the impact of depreciation, accretion and amortization, which is largely fixed and non-cash in nature. Segment Operating Profit is not intended to be an alternative measure of revenue or segment gross profit as determined in accordance with GAAP.

The increase in site leasing segment operating profit of $51.1 million in 2010 is primarily related to additional profit generated by the revenues from the towers that we acquired or constructed in the latter half of 2009 or subsequent to December 31, 2009, organic site leasing growth from new leases and contractual rent escalators and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers in the year ended December 31, 2010, control of our site leasing cost of revenue and the positive impact of our ground lease purchase program.

The increase in site leasing segment operating profit of $65.8 million in 2009 is primarily related to additional profit generated by the revenues from the towers that we acquired in the 2008 acquisitions of Optasite, Light



Tower and Tower Co and other towers that we acquired or constructed in the latter half of 2008 or subsequent to December 31, 2008, organic site leasing growth from new leases and contractual rent escalators and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers in the year ended December, 31 2009, control of our site leasing cost of revenue and the positive impact of our ground lease purchase program.

Each respective Segment Operating Profit is defined as segment revenues less segment cost of revenues (excluding depreciation, accretion and amortization).

## Adjusted EBITDA

We believe that Adjusted EBITDA is an indicator of the performance of our core operations and reflects the changes in our operating results. Adjusted EBITDA is a component of the calculation that has been used by our lenders to determine compliance with certain covenants under our 2010 Credit Facility (as defined below) and Senior Notes (as defined below). Adjusted EBITDA is not intended to be an alternative measure of operating income or gross profit margin as determined in accordance with GAAP.

We define Adjusted EBITDA as net loss excluding the impact of net interest expenses (including amortization of deferred financing fees), provision for taxes, depreciation, accretion and amortization, asset impairment and other charges, non-cash compensation, net loss (gain) from extinguishment of debt, other income and expenses, acquisition related expenses, non-cash straight-line leasing revenue and non-cash straight-line ground lease expense. Adjusted EBITDA excludes acquisition related costs which were previously capitalized but, commencing January 1, 2009, were required to be expensed and included within operating expenses pursuant



to the adoption of new business combination accounting guidance. The reconciliation of Adjusted EBITDA is as follows:

(1) Interest expense includes cash interest expense, non-cash interest expense and amortization of deferred financing fees.

(2) Includes $1,899, $1,712 and $1,334 of franchise taxes reflected on the Statement of Operations in selling, general and administrative expenses for the year ended 2010, 2009 and 2008, respectively.

Adjusted EBITDA was $387.4 million for the year ended December 31, 2010 as compared to $338.5 million for the year ended December 31, 2009. The increase of $48.9 million is primarily the result of increased segment operating profit from our site leasing segment.

Adjusted EBITDA was $338.5 million for the year ended December 31, 2009 as compared to $269.2 million for the year ended December 31, 2008. The increase of $69.3 million is primarily the result of increased segment operating profit from our site leasing segment.

## Revenues:

Site leasing revenue increased $58.4 million for the year ended December 31, 2010 largely due to (i) revenues from the towers that we acquired or constructed in the latter half of 2009 or subsequent to December 31, 2009 and (ii) organic site leasing growth from new leases and contractual rent escalators with current tenants and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers.



Site development consulting revenue increased $1.8 million and site development construction revenues increased $10.9 million for the year ended December 31, 2010, as compared to the year ended December 31, 2009, as a result of a higher volume of work associated with continued network expansion of the wireless carriers.

## Operating Expenses:

Site leasing cost of revenues increased $7.3 million primarily as a result of the growth in the number of tower sites owned by us, which was 9,111 at December 31, 2010 up from 8,324 at December 31, 2009 offset by the positive impact of our ground lease purchase program.

Site development consulting cost of revenues increased $1.7 million and site development construction cost of revenues increased $9.9 million for the year ended December 31, 2010, as compared to the prior year, as a result of a higher volume of work performed during 2010 as compared to 2009.

Selling, general, and administrative expenses increased $5.4 million primarily as a result of an increase in salaries, benefits and other employee related expenses resulting primarily from a higher number of employees, increased non-cash compensation expense as well as costs incurred in connection with our international expansion.

Acquisition related expenses increased $5.3 million for the year ended December 31, 2010, as compared to the prior year, primarily as a result of an increase in the number of towers acquired as well as under contract for acquisition during 2010 as compared to 2009.

We recognized an asset impairment charge of $5.9 million for the year ended December 31, 2010 and $3.9 million for the year ended December 31, 2009. These asset impairment charges resulted from a reevaluation of (i) future cash flow expectations, using a discounted cash flow analysis, for those towers (59 towers in 2010 and 21 towers in 2009) that have not achieved expected lease-up results, compared to (ii) the related net book value of those towers. In addition, the asset impairment charge for 2009 included an impairment charge on our six DAS networks based on their estimated fair value at December 31, 2009.

Depreciation, accretion and amortization expense increased $20.2 million to $278.7 million for the year ended December 31, 2010 from $258.5 million for the year ended December 31, 2009 due to an increase in the number of towers and associated intangible assets owned for the year ended December 31, 2010 compared to those owned at December 31, 2009.

## Operating Income:

Operating income increased $19.3 million for year ended December 31, 2010 to $74.3 million compared to $55.0 million for the year ended December 31, 2009 primarily due to the result of higher segment operating profit in the site leasing segment partially offset by increases in depreciation, accretion and amortization expense, acquisition related expenses and selling, general and administrative expenses.

## Other Income (Expense):

Interest income decreased $0.7 million for the year ended December 31, 2010 compared to the year ended December 31, 2009 primarily as a result of the lower weighted average interest rates during 2010 compared to 2009.

Interest expense for the year ended December 31, 2010 increased $19.1 million from the year ended December 31, 2009 primarily due to the higher weighted average amount of cash-interest bearing debt



outstanding offset by the lower weighted average interest rate for the year ended December 31, 2010 as compared to the year ended December 31, 2009.

Non-cash interest expense for the year ended December 31, 2010 increased $10.2 million from the year ended December 31, 2009 primarily as a result of accretion of debt discounts using the effective interest method on the 1.875% Notes, the 4.0% Notes, and the Senior Notes, offset by the impact of the repurchase of an aggregate of $107.7 million in principal of the 0.375% Notes during 2009 and repayment of the Optasite Credit Facility in July 2009.

The loss from extinguishment of debt of $49.1 million for the year ended December 31, 2010 is primarily associated with the repayment of the outstanding balance of $938.6 million in principal of our 2006 CMBS Certificates. The net loss from extinguishment of debt of $5.7 million for the year ended December 31, 2009 includes a loss of $7.2 million related to the repurchases and subsequent payoff of our 2005 CMBS Certificates in July 2009, $2.7 million associated with the repurchase of $150.1 million in principal of our 2006 CMBS Certificates and $1.9 million related to the payoff of our Optasite Credit Facility in July 2009, offset by a gain of $6.1 million associated with the repurchases of an aggregate of $107.7 million in principal of our 0.375% Notes.

## Net Loss:

Net loss was $194.4 million for the year ended December 31, 2010 as compared to $141.1 million for the year ended December 31, 2009. The net loss increased in 2010 primarily due to the loss on extinguishment of debt of $49.1 million, increases in interest expense, non-cash interest expense, and depreciation, accretion and amortization expense partially offset by an increase in site leasing segment operating profit.

## Revenues:

Site leasing revenue increased $81.5 million for the year ended December 31, 2009 largely due to (i) revenues from the towers that we acquired in the 2008 acquisitions of Optasite, Light Tower and Tower Co and the other towers that we acquired or constructed subsequent to December 31, 2008 and (ii) organic site leasing growth from new leases and contractual rent escalators and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers. Average rents per tenant increased in the year ended December 31, 2009 due primarily to rent escalators, lease amendments and higher rents associated with new leases.

Site development consulting revenue decreased $1.3 million for the year ended December 31, 2009, compared to the same period in the prior year, as a result of a lower volume of work. Site development construction revenues remained relatively stable for the year ended December 31, 2009 as compared to the year ended December 31, 2008.



## Operating Expenses:

Site leasing cost of revenues increased $15.7 million primarily as a result of the growth in the number of tower sites owned by us, which was 8,324 at December 31, 2009 up from 7,854 at December 31, 2008, offset by the positive impact of our ground lease purchase program.

Site development consulting cost of revenues decreased by $2.0 million and site development construction cost of revenues decreased by $1.3 million for the year ended December 31, 2009, as compared to the same period in the prior year, as a result of lower volume of work and continued effort to manage and reduce fixed overhead costs.

Selling, general, and administrative expenses increased $4.1 million primarily as a result of an increase in salaries, benefits and other employee related expenses resulting primarily from a higher number of employees, and increased non-cash compensation expense that we recognized for the year ended December 31, 2009 compared to the year ended December 31, 2008.

Acquisition related expenses of $4.8 million are associated with acquisitions which effective January 1, 2009, are required to be expensed and included within operating expenses. We had historically capitalized the majority of these expenses.

Asset impairment of $3.9 million for the year ended December 31, 2009 is a result of a reevaluation of future cash flow expectations for 21 towers that have not achieved expected lease-up results as determined using a discounted cash flow analysis compared to the related net book value of the tower assets and an impairment charge on our six DAS networks based on the estimated fair value of the DAS networks at December 31, 2009. Asset impairment of $0.9 million for the year ended December 31, 2008 is a result of a reevaluation of future cash flow expectations for 8 towers that have not achieved expected lease-up results as determined using a discounted cash flow analysis compared to the related net book value of the tower asset and related intangibles.

Depreciation, accretion and amortization expense increased $47.1 million to $258.5 million for the year ended December 31, 2009 from $211.4 million for the year ended December 31, 2008 due to an increase in the number of towers and associated intangible assets we owned for the year ended December 31, 2009 compared to those owned at December 31, 2008.

## Operating Income:

Operating income increased $9.4 million for year ended December 31, 2009 to $55.0 million compared to $45.6 million for the year ended December 31, 2008 primarily due to the result of higher segment operating profit in the site leasing segment partially offset by increases in depreciation, accretion and amortization expense, acquisition related expenses and selling, general and administrative expenses.

## Other Income (Expense):

Interest income decreased $5.8 million for the year ended December 31, 2009 compared to the year ended December 31, 2008 primarily as a result of lower weighted average interest rates offset by higher average invested funds during 2009 compared to 2008.

Interest expense for the year ended December 31, 2009 increased $25.5 million from the year ended December 31, 2008 primarily due to the higher interest rates on the mix of our outstanding debt and the higher weighted average amount of cash interest bearing debt outstanding for the year ended December 31, 2009 as compared to the year ended December 31, 2008.



Non-cash interest expense for the year ended December 31, 2009 increased $16.6 million from the year ended December 31, 2008 primarily as a result of the accretion of debt discounts on the Senior Notes which were issued in July 2009 and the 4.0% Notes which were issued in April 2009 and the Optasite Credit Facility acquired in September 2008, offset by the impact of the repurchase of an aggregate of $319.6 million in principal of the 0.375% Notes in the fourth quarter of 2008 and year ended December 31, 2009.

The net loss from extinguishment of debt of $5.7 million for the year ended December 31, 2009 includes a loss of $7.2 million related to the repurchases and subsequent payoff of our 2005 CMBS Certificates in July 2009, $2.7 million associated with the repurchase of $150.1 million in principal of our 2006 CMBS Certificates and $1.9 million related to the payoff of our Optasite Credit Facility in July 2009, offset by a gain of $6.1 million associated with the repurchases of an aggregate of $107.7 million in principal of our 0.375% Notes. The net gain from extinguishment of debt of $44.3 million for the year ended December 31, 2008 included $25.7 million related to the repurchase of $211.9 million in principal amount of our 0.375% Notes and $18.9 million related to the repurchases of $65.5 million of our CMBS Certificates offset by the write-off of deferred financing fees related to the portion of the debt extinguished and the reduction in the aggregate commitment of the lenders under the Senior Credit Facility as a result of Lehman Commercial Paper Inc.'s default of its funding obligations. See discussion in Note 12 to the Notes to the Consolidated Financial Statements for more information.

Other income (expense) for the year ended December 31, 2009 decreased $13.6 million from the year ended December 31, 2008 primarily as a result of an other-than-temporary impairment charge on our investments in auction rate securities during 2008. See Note 4 of our Consolidated Financial Statements for more information on our investments in auction rate securities and this other-than-temporary impairment charge.

## Net Loss:

Net loss increased by $74.0 million to $141.1 million for the year ended December 31, 2009 primarily as a result of: the 2009 net losses from the early extinguishment of debt as opposed to net gains from the early extinguishment of debt in 2008, increases in interest expense, non-cash interest expense, and depreciation, accretion and amortization expense partially offset by an increase in site leasing segment operating profit.

## LIQUIDITY AND CAPITAL RESOURCES

SBA Communications Corporation is a holding company with no business operations of its own. SBA Communications’ only significant asset is the outstanding capital stock of SBA Telecommunications, Inc.

## Sources of Liquidity

We fund our growth, including our tower portfolio growth, through cash flows from operations, long-term indebtedness and equity issuances. With respect to our debt financing, we have utilized secured and unsecured financings and issuances at various levels of our organizational structure to minimize our financing costs while maximizing our operational flexibility.

Cash provided by operating activities was $201.2 million for the year ended December 31, 2010 as compared to $222.6 million for the year ended December 31, 2009. This decrease was primarily due to the timing of interest payments relating to the higher average amount of cash-interest bearing debt outstanding for the year ended December 31, 2010, compared to the same period in the prior year, offset by an increase in segment operating profit from the site leasing segment.

On February 11, 2010, SBA Senior Finance II, LLC (“SBA Senior Finance II”), our indirect wholly-owned subsidiary, entered into a credit agreement for a $500.0 million senior secured revolving credit facility (the “2010 Credit Facility”) with several banks and other financial institutions or entities from time to time parties to the credit agreement (the “Credit Agreement”). Amounts borrowed under the 2010 Credit Facility are secured by a first lien on the capital stock of Telecommunications, SBA Senior Finance and SBA Senior Finance II, and substantially all of the assets, other than leasehold, easement or fee interests in real property, of SBA Senior Finance II and the Subsidiary Guarantors (as defined in the Credit Agreement). The 2010 Credit Facility matures on February 11, 2015 and may be borrowed, repaid and redrawn, subject to compliance with the financial and other covenants in the Credit Agreement. As of December 31, 2010, we had $20.0 million outstanding under the 2010 Credit Facility and the weighted average interest rate for the amounts borrowed was 2.15%. As of December 31, 2010, the availability under the 2010 Credit Facility was $480.0 million. Proceeds under the 2010 Credit Facility may be used for general corporate purposes. The material terms of the 2010 Credit Facility are described below under "Debt Instruments and Debt Service Requirements – 2010 Credit Facility."

On April 16, 2010, a New York common law trust (the "Trust"), initially formed by our indirect subsidiary, issued $680.0 million of Secured Tower Revenue Securities Series 2010-1 (the "2010-1 Tower Securities"), and $550.0 million of Secured Tower Revenue Securities Series 2010-2 (the "2010-2 Tower Securities" and together with the 2010-1 Tower Securities, the "2010 Tower Securities"). The weighted average annual fixed coupon interest rate of the 2010 Tower Securities is 4.6%, payable monthly. The anticipated repayment date and the final maturity date for the 2010–1 Tower Securities is April 16, 2015 and April 16, 2040, respectively. The anticipated repayment date and the final maturity date for the 2010–2 Tower Securities is April 16, 2017 and April 16, 2042, respectively. The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of SBA Properties, Inc., SBA Sites, Inc., and SBA Structures, Inc., our indirect operating subsidiaries (the "Borrowers"). The mortgage loan consists of two components, each with terms that are identical to the series of 2010 Tower



Securities to which it relates. The Borrowers are special purpose vehicles which exist solely to hold the towers which are subject to the securitization. The Borrowers are jointly and severally liable for all obligations under the mortgage loan. The material terms of the 2010 Tower Securities are described below under — “Debt Instruments and Debt Service Requirements – Secured Tower Revenue Securities Series 2010”.

## Registration Statements

We have on file with the Commission a shelf registration statement on Form S-4 registering shares of Class A common stock that we may issue in connection with the acquisition of wireless communication towers or antenna sites and related assets or companies who own wireless communication towers, antenna sites or related assets. During the year ended December 31, 2010, we did not issue any shares of Class A common stock under this registration statement. As of December 31, 2010, we had approximately 1.7 million shares of Class A common stock remaining under this shelf registration statement.

On March 3, 2009, we filed with the Commission an automatic shelf registration statement for well-known seasoned issuers on Form S-3ASR. This registration statement enables us to issue shares of our Class A common stock, preferred stock or debt securities either separately or represented by warrants, or depositary shares as well as units that include any of these securities. Under the rules governing automatic shelf registration statements, we will file a prospectus supplement and advise the Commission of the amount and type of securities each time we issue securities under this registration statement. For the year ended December 31, 2010, we did not issue any securities under this automatic shelf registration statement.

## Uses of Liquidity

We believe that our principal use of liquidity will be to fund tower portfolio growth and, secondarily, to fund our stock repurchase program. In the future, we may repurchase, for cash or equity, our outstanding indebtedness in privately-negotiated or open market transactions in order to optimize our liquidity and leverage and take advantage of market opportunities.

Our cash capital expenditures, including cash used for acquisitions, for the year ended December 31, 2010 were $394.7 million. The $394.7 million includes cash capital expenditures of $303.1 million that we incurred primarily in connection with the acquisition of 712 completed towers, net of related working capital adjustments and earmouts associated with previous acquisitions. The $394.7 million also includes $46.9 million for construction and related costs associated with the completion of 124 new towers during the year ended December 31, 2010 and for the sites in process at December 31, 2010, $8.2 million for tower maintenance capital expenditures, $9.4 million for augmentations and tower upgrades, $2.1 million for general corporate expenditures, and $25.0 million for ground lease purchases (not including $9.0 million spent to extend ground lease terms).

Subsequent to December 31, 2010, we acquired 123 towers and related assets and liabilities from various sellers. The aggregate consideration paid for the towers and related assets was approximately $63.6 million in cash.

Pursuant to the terms of the Indenture, on or prior to November 26, 2010, we received conversion notices from holders of an aggregate of $30.3 million in principal of our 0.375% Notes. Pursuant to Section 10.02 of the Indenture, these notes were converted at a price of $1,152.78 per $1,000 of principal or an aggregate of $34.9 million. Concurrently with the settlement of our conversion obligation, we settled two convertible note hedge transactions that we had initially purchased at the time the 0.375% Notes were issued. In connection with the settlement of these options, we received an aggregate of $13.1 million (including $8.5 million attributable to a portion held by our wholly-owned subsidiary). The remaining $120,000 aggregate principal amount of 0.375% Notes that was not earlier converted or repurchased matured on December 1, 2010. On December 1, 2010, we satisfied our obligation on the notes held to maturity by paying $120,000 in cash plus accrued interest.



On April 16, 2010, we used the proceeds from the issuance of our 2010 Tower Securities to repay the remaining principal balance of $938.6 million of the 2006 CMBS Certificates and to pay $38.5 million for related prepayment consideration plus accrued interest and fees. During the year-to-date period ended December 31, 2010, but prior to the payoff of the principal balance, we repurchased an aggregate of $2.0 million in principal amount of 2006 CMBS Certificates for $2.1 million in cash.

The Board of Directors authorized a stock repurchase program effective November 3, 2009. This program authorizes us to purchase, from time to time, up to $250.0 million of our outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Act of 1933, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program will continue until otherwise modified or terminated by our Board of Directors at any time in our sole discretion. During the year ended December 31, 2010, we repurchased and retired approximately 3,174,385 shares for an aggregate of $107.4 million including commissions and fees. As of December 31, 2010 we had a remaining authorization to repurchase an additional $140.9 million of our common stock under our current $250.0 million stock repurchase program.

In order to manage our leverage and liquidity positions, take advantage of market opportunities and ensure continued compliance with our financial covenants, we may decide to pursue a variety of other financial transactions. These transactions may include the issuance of additional indebtedness, the repurchase of our outstanding indebtedness for cash or equity, selling certain assets or lines of business, issuing common stock or securities convertible into shares of common stock, or pursuing other financing alternatives, including securitization transactions. If either our debt repurchases or exchanges or any of the other financial transactions are implemented, these actions could materially impact the amount and composition of indebtedness outstanding, increase our interest expense and/or dilute our existing shareholders. We cannot assure you that we will not implement any of these strategies or that, if implemented, these strategies could be implemented on terms favorable to us and our shareholders.

During 2011, we expect to incur non-discretionary cash capital expenditures associated with tower maintenance and general corporate expenditures of $10.0 million to $14.0 million and discretionary cash capital expenditures, based on current obligations, of $230.0 million to $250.0 million primarily associated with the towers we intend to build in 2011, tower acquisitions closed or currently under contract, tower augmentations and ground lease purchases. We may spend additional capital in 2011 on acquiring revenue producing or expense reducing assets not yet identified and under contract, or possibly stock repurchases.

We estimate we will incur less than $1,000 per tower per year for non-discretionary maintenance capital improvements related to our towers. We expect to fund cash capital expenditures from cash on hand, cash flow from operations and borrowings under the 2010 Credit Facility. The exact amount of our future capital expenditures will depend on a number of factors including amounts necessary to support our tower portfolio, our new tower build and tower acquisition programs, and our ground lease purchase program.

## Debt Instruments and Debt Service Requirements

As of December 31, 2010, we believe that our cash on hand and cash flows from operations will be sufficient to service our outstanding debt during the next twelve months.



## Commercial Mortgage Pass-Through Certificates Series 2006-1

On November 6, 2006, a New York common law trust (the “Trust”), formed by our indirect subsidiary, issued in a private transaction $1.15 billion of Commercial Mortgage Pass-Through Certificates Series 2006-1 (the “2006 CMBS Certificates”).

The 2006 CMBS Certificates consisted of nine subclasses with annual pass-through interest rates ranging from 5.314% to 7.825%. The weighted average annual fixed interest rate of the 2006 CMBS Certificates was 5.9%, payable monthly, and the effective weighted average annual fixed interest rate was 6.2% after giving effect to the settlement of the nine interest rate swap agreements entered into in contemplation of the transaction.

On April 16, 2010, we paid off the remaining outstanding balance of $938.6 million on the 2006 CMBS Certificates and paid $38.5 million in related prepayment consideration plus accrued interest and fees.

## Secured Tower Revenue Securities Series 2010

The 2010-1 Tower Securities have an annual interest rate of 4.254% and the 2010-2 Tower Securities have an annual interest rate of 5.101%. The weighted average annual fixed coupon interest rate of the 2010 Tower Securities is 4.6%, payable monthly. The anticipated repayment date and the final maturity date for the 2010–1 Tower Securities is April 16, 2015 and April 16, 2040, respectively. The anticipated repayment date and the final maturity date for the 2010–2 Tower Securities is April 16, 2017 and April 16, 2042, respectively. Net proceeds from the 2010 Tower Securities were used to repay in full the outstanding 2006 CMBS Certificates in the amount of $938.6 million and pay the related prepayment consideration plus accrued interest and fees. The remaining net proceeds were used for general corporate purposes.

The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of the Borrowers. The Borrowers are special purpose vehicles which exist solely to hold the towers which are subject to the securitization. In connection with the issuance of the 2010 Tower Securities and the repayment of the 2006 CMBS Certificates, the mortgage loan components relating to the 2006 CMBS Certificates were repaid and the mortgage loan was amended to create two new loan components, each with terms that are identical to the series of 2010 Tower Securities to which it relates. The Borrowers are jointly and severally liable for all obligations under the mortgage loan.

The mortgage loan underlying the 2010 Tower Securities will be paid from the operating cash flows from the aggregate 3,683 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust and deeds to secure debt on a substantial portion of the tower sites, (ii) a security interest in substantially all of the Borrowers’ personal property and fixtures, (iii) the Borrowers’ rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., our indirect subsidiary, is entitled to receive a management fee equal to 7.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay either of the mortgage loan components, in whole or in part, with no prepayment consideration, (i) within nine months of the anticipated repayment date of such mortgage loan component, (ii) with proceeds received as a result of any condemnation or casualty of any tower site owned by the Borrowers or (iii) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of 2010 Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid.



from the date of prepayment to and including the first due date that is nine months prior to the anticipated repayment date over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the 2010 Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any, by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the 2010 Tower Securities, all rents and other sums due on any of the tower sites owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as restricted cash on our Consolidated Balance Sheets. However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of December 31, 2010, the Borrowers met the required Debt Service Coverage Ratio. Based on the amounts outstanding at December 31, 2010, debt service for the next twelve months on the 2010 Tower Securities would be $57.0 million.

## Convertible Senior Notes

0.375% Convertible Senior Notes - On March 26, 2007, we issued $350.0 million of our 0.375% Convertible Senior Notes (the “0.375% Notes”). Interest was payable semi-annually on June 1 and December 1. The 0.375% Notes had a maturity date of December 1, 2010. The 0.375% Notes were convertible, at the holder’s option, at any time between October 12, 2010 and November 26, 2010, into shares of our Class A common stock, at an initial conversion rate of 29.7992 shares of Class A common stock per $1,000 principal amount of 0.375% Notes (subject to certain customary adjustments), which was equivalent to an initial conversion price of approximately $33.56 per share. Pursuant to the terms of the Indenture, upon conversion, we had the right to settle our conversion obligation in cash, shares of Class A common stock or a combination of cash and shares of our Class A common stock. On October 5, 2010, we provided notice to the trustee and holders of our 0.375% Notes that we had elected to settle 100% of our conversion obligation relating to the 0.375% Notes in cash. During the fourth quarter of 2010, we converted or repaid at maturity all outstanding 0.375% Notes.

1.875% Convertible Senior Notes - On May 16, 2008 we issued $550.0 million of our 1.875% Notes. Interest is payable semi-annually on May 1 and November 1. The maturity date of the 1.875% Notes is May 1, 2013. The 1.875% Notes are convertible, at the holder’s option, into shares of our Class A common stock, at an initial conversion rate of 24.1196 shares of Class A common stock per $1,000 principal amount of 1.875% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $41.46 per share or a 20% conversion premium based on the last reported sale price of $34.55 per share of Class A common stock on the Nasdaq Global Select Market on May 12, 2008, the purchase agreement date.



Concurrently with the pricing of the 1.875% Notes, we entered into convertible note hedge transactions covering 13,265,780 shares of our Class A common stock at an initial price of $41.46 per share (the same as the initial conversion price of the 1.875% Notes). Separately and concurrently with the pricing of the 1.875% Notes, we entered into warrant transactions whereby we sold warrants to each of the hedge counterparties to acquire 13,265,780 shares of our Class A common stock at an initial exercise price of $67.37 per share. The convertible note hedge transactions and the warrant transactions, taken as a whole, effectively increase the conversion price of the 1.875% Notes from $41.46 per share to $67.37 per share. As we cannot determine when, or whether, the 1.875% Notes will be converted, the convertible note hedge transactions and the warrant transactions, taken as a whole, minimize the dilution risk associated with early conversion of the 1.875% Notes until such time that our Class A common stock is trading at a price above $67.37 per share (the upper strike of the warrants).

One of the convertible note hedge transactions entered into in connection with the 1.875% Notes was with Lehman Brothers OTC Derivatives Inc. (“Lehman Derivatives”). The convertible note hedge transaction with Lehman Derivatives covers 55% of the 13,265,780 shares of our Class A common stock potentially issuable upon conversion of the 1.875% Notes. In October 2008, Lehman Derivatives filed a voluntary petition for protection under Chapter 11 of the United States Bankruptcy Code. The filing by Lehman Derivatives of a voluntary Chapter 11 bankruptcy petition constituted an “event of default” under the convertible note hedge transaction with Lehman Derivatives. As a result, on November 7, 2008 we terminated the convertible note hedge transaction with Lehman Derivatives. Based on information available to us, we have no indication, as of the date of filing this Form 10-K, that any party other than Lehman Derivatives would be unable to fulfill their obligations to us under the convertible note hedge transactions.

The net cost of the convertible note hedge transaction with Lehman Derivatives was recorded as an adjustment to Additional Paid in Capital and therefore the termination of the convertible note hedge did not have any impact on our consolidated balance sheet. However, we could incur significant costs to replace this hedge transaction if we elect to do so. If we do not elect to replace the convertible note hedge transaction, then we will be subject to potential dilution upon conversion of the 1.875% Notes, if on the date of conversion the per share market price of our Class A common stock exceeds the conversion price of $41.46.

At December 31, 2010, we had $550.0 million outstanding of 1.875% Notes. Based on the amounts outstanding at December 31, 2010, debt service for the next twelve months on the 1.875% Notes will be approximately $10.3 million.

4.0% Convertible Senior Notes - On April 24, 2009, we issued $500.0 million of our 4.0% Notes in a private placement transaction. Interest on the 4.0% Notes is payable semi-annually on April 1 and October 1. The maturity date of the 4.0% Notes is October 1, 2014. The 4.0% Notes are convertible, at the holder's option, into shares of our Class A common stock, at an initial conversion rate of 32.9164 shares of our Class A common stock per $1,000 principal amount of 4.0% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $30.38 per share or a 22.5% conversion premium based on the last reported sale price of $24.80 per share of our Class A common stock on the Nasdaq Global Select Market on April 20, 2009, the purchase agreement date.

Concurrently with the pricing of the 4.0% Notes, we entered into convertible note hedge transactions whereby we purchased from affiliates of the initial purchasers of the 4.0% Notes an option covering 16,458,196 shares of our Class A common stock at an initial price of $30.38 per share (the same as the initial conversion price of the notes). Separately and concurrently with the pricing of the 4.0% Notes, we entered into warrant transactions whereby we sold to affiliates of the initial purchasers of the 4.0% Notes warrants to acquire 16,458,196 shares of our Class A common stock at an initial exercise price of $44.64 per share. We used approximately $61.6 million of the net proceeds from the 4.0% Notes offering plus the proceeds from the warrant transactions to fund the cost of the convertible note hedge transactions. The convertible note hedge transactions and the warrant transactions, taken as a whole, effectively increase the conversion price of the 4.0% Notes from $30.38 per share to $44.64 per



share, reflecting a premium of 80% based on the closing stock price of $24.80 per share of our Class A common stock on April 20, 2009. If the market price of our Class A common stock exceeded the upper strike price of $44.64 per share on the conversion date of the 4.0% Notes, then we will be subject to dilution or cost upon conversion of the 4.0% Notes. The remaining net proceeds of $376.6 million were used for general corporate purposes, including repurchases or repayments of our outstanding debt.

As of December 31, 2010, we had outstanding $500.0 million of our 4.0% Notes. Based on the amounts outstanding at December 31, 2010, debt service for the next twelve months on the 4.0% Notes would be approximately $20.0 million.

Convertible Senior Notes conversion options - The 1.875% Notes and 4.0% Notes (collectively “the Notes”) are convertible only under the following circumstances:

- during any calendar quarter, if the last reported sale price of our Class A common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last trading day of the preceding calendar quarter is more than 130% of the applicable conversion price per share of Class A common stock on the last day of such preceding calendar quarter,

- during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each day in the measurement period was less than 95% of the product of the last reported sale price of Class A common stock and the applicable conversion rate,

- if specified distributions to holders of Class A common stock are made or specified corporate transactions occur, and

- at any time on or after February 19, 2013 for the 1.875% Notes and July 22, 2014 for the 4.0% Notes.

Upon conversion, we have the right to settle our conversion obligation in cash, shares of Class A common stock or a combination of cash and shares of our Class A common stock. From time to time, upon notice to the holders of the Notes, we may change our election regarding the form of consideration that we will use to settle our conversion obligation; provided, however, that we are not permitted to change our settlement election after February 18, 2013 for the 1.875% Notes and July 21, 2014 for the 4.0% Notes.

## Senior Notes

On July 24, 2009, Telecommunications issued $750.0 million of unsecured senior notes (the “Senior Notes”), $375.0 million of which are due August 15, 2016 (the “2016 Notes”) and $375.0 million of which are due August 15, 2019 (the “2019 Notes”). At December 31, 2010, we had $375.0 million of 2016 Notes outstanding, which were recorded at a carrying value of $372.9 million, and $375.0 million of 2019 Notes outstanding, which were recorded at a carrying value of $372.1 million.

The 2016 Notes have an interest rate of 8.00% and were issued at a price of 99.330% of their face value. The 2019 Notes have an interest rate of 8.25% and were issued at a price of 99.152% of their face value. Interest on the 2016 Notes and 2019 Notes is due semi-annually on February 15 and August 15 of each year beginning on February 15, 2010. Based on the amounts outstanding at December 31, 2010, debt service for the next twelve months on the 2016 Senior Notes and the 2019 Senior Notes would be $30.0 million and $30.9 million, respectively. The 2016 Notes and the 2019 Notes are fully and unconditionally guaranteed by SBA Communications.



The 2016 Notes and the 2019 Notes are subject to redemption in whole or in part on or after August 15, 2012 and on or after August 15, 2014, respectively, at the redemption prices set forth in the indenture agreement plus accrued and unpaid interest. Prior to August 15, 2012 for the 2016 Notes and August 15, 2014 for the 2019 Notes, we may at our option redeem all or a portion of the 2016 Notes or 2019 Notes at a redemption price equal to 100% of the principal amount thereof plus a “make whole” premium plus accrued and unpaid interest. In addition, we may redeem up to 35% of the originally issued aggregate principal amount of each of the 2016 Notes and 2019 Notes with the net proceeds of certain equity offerings at a redemption price of 108.00% and 108.25%, respectively, of the principal amount of the redeemed notes plus accrued and unpaid interest.

The Indenture governing the Senior Notes contains customary covenants, subject to a number of exceptions and qualifications, including restrictions on Telecommunications’ ability to (1) incur additional indebtedness unless its Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio (as defined in the Indenture), pro forma for the additional indebtedness, does not exceed 7.0x for the fiscal quarter, (2) merge, consolidate or sell assets, (3) make restricted payments, including dividends or other distributions, (4) enter into transactions with affiliates, and (5) enter into sale and leaseback transactions and restrictions on the ability of Telecommunications’ Restricted Subsidiaries (as defined in the Indenture) to incur liens securing indebtedness.

On May 19, 2010, SBA Communications and Telecommunications filed a registration statement on Form S-4 with the Commission pursuant to which Telecommunications offered to (1) exchange all of its outstanding unregistered $375.0 million 8.00% Senior Notes due 2016 for registered $375.0 million 8.00% Senior Notes due 2016, and (2) exchange all of its outstanding unregistered $375.0 million 8.25% Senior Notes due 2019 for registered $375.0 million 8.25% Senior Notes due 2019. On July 15, 2010, the exchange offer was consummated.

## 2010 Credit Facility

The 2010 Credit Facility consists of a revolving loan up to $500.0 million, based on SBA Senior Finance II’s ratio of Annualized Adjusted EBITDA to Consolidated Total Debt plus Net Hedge Exposure, may be borrowed, repaid and redrawn subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing, as set forth in the Credit Agreement. Amounts borrowed under the 2010 Credit Facility accrue interest at the Eurodollar rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate (as defined in the Credit Agreement) plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (as defined in the Credit Agreement). A 0.375% to 0.5% per annum fee is charged on the amount of unused commitment. Unless terminated earlier, the 2010 Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, February 11, 2015. Proceeds available under the 2010 Credit Facility may be used for general corporate purposes. As of December 31, 2010, we had $20.0 million outstanding under the 2010 Credit Facility and the weighted average interest rate for the amounts borrowed was 2.15%. As of December 31, 2010, the availability under the 2010 Credit Facility was $480.0 million. We may, from time to time, borrow from and repay the 2010 Credit Facility. Consequently, the amount outstanding under the 2010 Credit Facility at the end of a period may not be reflective of the total amounts outstanding during the period. Based on the amounts outstanding under the 2010 Credit Facility at December 31, 2010, debt service for the next twelve months will be approximately $0.4 million for the amounts borrowed and $1.8 million for the unused commitment.

The Credit Agreement requires SBA Senior Finance II and SBA Communications to maintain specific financial ratios, including, at the SBA Senior Finance II level, a ratio of Consolidated Total Debt to Annualized Borrower EBITDA (as defined in the Credit Agreement) that does not exceed 5.0x for any fiscal quarter, a ratio of Consolidated Total Debt and Net Hedge Exposure (as defined in the Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 5.0x for 30 consecutive days and a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (as defined in the Credit Agreement) of not less than 2.0x for any fiscal quarter. In addition, our ratio of Consolidated Total Net Debt to Consolidated Adjusted EBITDA (as defined in the Credit Agreement) for any fiscal quarter on an annualized basis cannot



exceed 8.9x. The Credit Agreement also contains customary affirmative and negative covenants that, among other things, limit SBA Senior Finance II’s ability to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions or engage in certain asset dispositions, including a sale of all or substantially all of our assets. As of December 31, 2010, SBA Senior Finance II and SBA Communications were in full compliance with the financial covenants contained in the 2010 Credit Facility.

The 2010 Credit Facility also permits us to request that one or more lenders (1) increase their proportionate share of the 2010 Credit Facility commitment, up to an additional $200.0 million in the aggregate and (2) provide SBA Senior Finance II term loans for an aggregate amount up to $800.0 million, without requesting consent of the other lenders. SBA Senior Finance II's ability to request such increase of the 2010 Credit Facility or term loans is subject to its compliance with the conditions set forth in the Credit Agreement including, with respect to any term loan, compliance, on a pro forma basis, with the financial covenants and ratios set forth therein. Upon SBA Senior Finance II's request, each lender may decide, in its sole discretion, whether to increase all or a portion of its revolving credit facility commitment or whether to provide SBA Senior Finance II term loans and if so upon what terms.

## Senior Credit Facility

On January 18, 2008, SBA Senior Finance, our indirect wholly-owned subsidiary, entered into a Senior Credit Facility (the “Senior Credit Facility”) with several banks and other financial institutions or entities from time to time parties to the credit agreement.

Amounts borrowed under the facility accrued interest at the Eurodollar rate plus a margin that ranged from 150.0 basis points to 300.0 basis points or at a Base Rate (as defined in the Restated Credit Agreement) plus a margin that ranged from 50.0 basis points to 200.0 basis points, in each case based on the Consolidated Total Debt to Annualized Borrower EBITDA ratio (as defined in the Restated Credit Agreement). A 0.5% per annum fee was charged on the amount of unused commitment.

On February 11, 2010, we terminated our $320.0 million Senior Credit Facility. We had no borrowings under the Senior Credit Facility at the time of its termination. No early termination penalties were incurred by us as a result of the termination.

## Inflation

The impact of inflation on our operations has not been significant to date. However, we cannot assure you that a high rate of inflation in the future will not adversely affect our operating results particularly in light of the fact that our site leasing revenues are governed by long-term contracts with pre-determined pricing that we will not be able to increase in response to increases in inflation.

## ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks that are inherent in our financial instruments. These instruments arise from transactions entered into in the normal course of business.

The following table presents the future principal payment obligations and fair values associated with our long-term debt instruments assuming our actual level of long-term indebtedness as of December 31, 2010:

<table><tr><td></td><td>2011</td><td>2012</td><td>2013</td><td>2014</td><td>2015</td><td>Thereafter</td><td>Total</td><td>Fair Value</td></tr><tr><td></td><td></td><td></td><td></td><td colspan="5">(in thousands)</td></tr><tr><td>Debt:</td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>1.875% Convertible Senior Notes due 2013</td><td>$ -</td><td>$ -</td><td>$ 550,000</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 550,000</td><td>$ 617,375</td></tr><tr><td>4.0% Convertible Senior Notes due 2014</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 500,000</td><td>$ -</td><td>$ -</td><td>$ 500,000</td><td>$ 744,375</td></tr><tr><td>8.0% Senior Notes due 2016</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 375,000</td><td>$ 375,000</td><td>$ 405,938</td></tr><tr><td>8.25% Senior Notes due 2019</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 375,000</td><td>$ 375,000</td><td>$ 409,688</td></tr><tr><td>4.254% 2010-1 Tower Securities (1)</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 680,000</td><td>$ -</td><td>$ 680,000</td><td>$ 691,900</td></tr><tr><td>5.101% 2010-2 Tower Securities (2)</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 550,000</td><td>$ 550,000</td><td>$ 556,875</td></tr><tr><td>2010 Credit Facility</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ -</td><td>$ 20,000</td><td>$ -</td><td>$ 20,000</td><td>$ 20,000</td></tr></table>

(1) The anticipated repayment date and the final maturity date for the 2010–1 Tower Securities is April 16, 2015 and April 16, 2040, respectively.
(2) The anticipated repayment date and the final maturity date for the 2010–2 Tower Securities is April 16, 2017 and April 16, 2042, respectively.

Our current primary market risk exposure is interest rate risk relating to (1) our ability to meet financial covenants and (2) the impact of interest rate movements on any borrowings that we may incur under our 2010 Credit Facility, which are at floating rates. We manage the interest rate risk on our outstanding debt through our large percentage of fixed rate debt. While we cannot predict our ability to refinance existing debt or the impact interest rate movements will have on our existing debt, we continue to evaluate our financial position on an ongoing basis. In addition, in connection with our convertible notes, we are subject to market risk associated with the market price of our common stock.

- the impact of recent consolidation among wireless service providers on our leasing revenue;

- our ability to secure as many site leasing tenants as anticipated and our ability to retain current leases on towers;

- our ability to recognize our expected economies of scale with respect to new tenants on our towers and new towers in our portfolio and additional expenses or capital expenditures that we may be required to incur to capture the additional revenue;

- factors that would adversely impact our ability to build the anticipated number of new towers, including our ability to identify and acquire land that would be attractive for our clients and to successfully and timely address zoning, permitting and other issues that arise in connection with the building of new towers;

- competition for the acquisition of towers and other factors that may adversely affect our ability to purchase towers that meet our investment criteria and are available at prices which we believe will be accretive to our shareholders and allow us to maintain our long-term target leverage ratios;

- our ability to successfully manage the risks associated with international operations, including foreign exchange risk, currency restrictions and foreign regulatory and legal risks;

- our intent and ability to continue our ground lease purchase program and the effect of such ground lease purchases on our margins and long-term financial condition;

- our ability to secure and deliver anticipated services business at contemplated margins;

- our ability to continue to comply with covenants and the terms of our credit instruments;

- our ability to successfully estimate the impact of certain accounting and tax matters, including the effect on our company of adopting certain accounting pronouncements and the availability of sufficient net operating losses to offset future taxable income; and

- natural disasters and other unforeseen damage for which our insurance may not provide adequate coverage.

## ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

## ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures - We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

In connection with the preparation of this Annual Report on Form 10-K, as of December 31, 2010, an evaluation was performed under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on such evaluation, our CEO and CFO concluded that, as of December 31, 2010, our disclosure controls and procedures were effective.

There has been no change in our internal control over financial reporting during the quarter ended December 31, 2010 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting -Management is responsible for establishing and maintaining adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2010. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our system of internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of SBA; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of SBA are being made only in accordance with authorizations of management and directors of SBA; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of SBA's assets that could have a material effect on the financial statements.

Management performed an assessment of the effectiveness of SBA's internal control over financial reporting as of December 31, 2010 based upon criteria in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our assessment, management determined that SBA’s internal control over financial reporting was effective as of December 31, 2010 based on the criteria in Internal Control-Integrated Framework issued by COSO.



Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Ernst & Young LLP, the independent registered certified public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has issued an attestation report on SBA’s internal control over financial reporting.



# Report of Independent Registered Certified Public Accounting Firm

The Board of Directors and Shareholders of SBA Communications Corporation and Subsidiaries

We have audited SBA Communications Corporation and Subsidiaries' internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). SBA Communications Corporation and Subsidiaries' management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, SBA Communications Corporation and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of SBA Communications Corporation and Subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of operations, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2010 of SBA Communications Corporation and Subsidiaries and our report dated February 25, 2011 expressed an unqualified opinion thereon.

# REPORT OF INDEPENDENT REGISTERED CERTIFIED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of SBA Communications Corporation and Subsidiaries

We have audited the accompanying consolidated balance sheets of SBA Communications Corporation and Subsidiaries as of December 31, 2010 and 2009, and the related consolidated statements of operations, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2010. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of SBA Communications Corporation and Subsidiaries at December 31, 2010 and 2009, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), SBA Communications Corporation and Subsidiaries' internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 25, 2011 expressed an unqualified opinion thereon.

## 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements is as follows:

## a. Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the Company and its majority and wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

## b. Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company's construction contracts, stock-based compensation, valuation allowance related to deferred tax assets, fair value of long-lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, fair value of investments and asset retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and such differences could be material.

## c. Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in banks, money market funds, commercial paper and other marketable securities with an original maturity of three months or less at the time of purchase. These investments are carried at cost, which approximates fair value.

## d. Investments

Investment securities with original maturities of more than three months but less than one year at time of purchase are considered short-term investments. The Company’s short-term investments primarily consist of certificates of deposit with maturities of less than a year. Investment securities with maturities of more than a year are considered long-term investments and are classified in other assets on the accompanying Consolidated Balance Sheets. Long-term investments primarily consist of U.S. Treasuries, corporate bonds and preferred



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

securities. Gross purchases and sales of the Company’s investments are presented within “Cash flows from investing activities” on the Company’s Consolidated Statements of Cash Flows.

## e. Restricted Cash

The Company classifies all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. This includes cash held in escrow to fund certain reserve accounts relating to the 2010 Tower Securities and 2006 CMBS Certificates, for payment and performance bonds, and surety bonds issued for the benefit of the Company in the ordinary course of business (see Note 5).

## f. Property and Equipment

Property and equipment are recorded at cost or at estimated fair value (in case of acquired properties), adjusted for asset impairment and estimated asset retirement obligations. Costs associated with the development and construction of towers are capitalized as a cost of the towers. Costs for self-constructed towers include direct materials and labor, indirect costs and capitalized interest. Approximately $0.4 million and $0.2 million of interest cost was capitalized in 2010 and 2009, respectively.

Depreciation on towers and related components is provided using the straight-line method over the estimated useful lives, not to exceed the minimum lease term of the underlying ground lease. The Company defines the minimum lease term as the shorter of the period from lease inception through the end of the term of all tenant lease obligations in existence at ground lease inception, including renewal periods, or the ground lease term, including renewal periods. If no tenant lease obligation exists at the date of ground lease inception, the initial term of the ground lease is considered the minimum lease term. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the minimum lease term of the lease. For all other property and equipment, depreciation is provided using the straight-line method over the estimated useful lives.

The Company performs ongoing evaluations of the estimated useful lives of its property and equipment for depreciation purposes. The estimated useful lives are determined and continually evaluated based on the period over which services are expected to be rendered by the asset. If the useful lives of assets are reduced, depreciation may be accelerated in future years. Property and equipment under capital leases are amortized on a straight-line basis over the term of the lease or the remaining estimated life of the leased property, whichever is shorter, and the related amortization is included in depreciation expense. Expenditures for maintenance and repair are expensed as incurred.

Asset classes and related estimated useful lives are as follows:

Towers and related components 3 - 15 years

Furniture, equipment and vehicles 2 - 7 years

Buildings and improvements 5 - 10 years

Betterments, improvements and extraordinary repairs, which increase the value or extend the life of an asset, are capitalized and depreciated over the remaining estimated useful life of the respective asset. Changes in an asset’s estimated useful life are accounted for prospectively, with the book value of the asset at the time of the change being depreciated over the revised remaining useful life. There has been no material impact for changes in estimated useful lives for any years presented.



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## g. Deferred Financing Fees

Financing fees related to the issuance of debt have been deferred and are being amortized using the effective interest rate method over the expected length of related indebtedness (see Note 12).

## h. Deferred Lease Costs

The Company defers certain initial direct costs associated with the origination of tenant leases and lease amendments and amortizes these costs over the initial lease term, generally five years, or over the lease term remaining if related to a lease amendment. Such deferred costs were approximately $4.7 million, $4.0 million, and $3.8 million in 2010, 2009, and 2008, respectively. Amortization expense was $3.6 million, $3.3 million, and $2.7 million for the years ended December 31, 2010, 2009 and 2008, respectively, and is included in cost of site leasing on the accompanying Consolidated Statements of Operations. As of December 31, 2010 and 2009, unamortized deferred lease costs were $9.4 million and $8.3 million, respectively, and are included in other assets on the accompanying Consolidated Balance Sheets.

## i. Intangible Assets

The Company classifies as intangible assets the fair value of current leases in place at the acquisition date of towers and related assets (referred to as the “Current contract intangibles”), and the fair value of future tenant leases anticipated to be added to the acquired towers (referred to as the “Network location intangibles”). These intangibles are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years. For all intangible assets, amortization is provided using the straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived evenly over the life of the asset.

## j. Impairment of Long-Lived Assets

The Company records an impairment charge when the Company believes an investment in towers or related assets has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower site and related intangible. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an asset’s fair value for the purpose of calculating the amount of an impairment charge. The Company recorded an impairment charge of $5.9 million, $3.9 million and $0.9 million for the twelve months ended December 31, 2010, 2009 and 2008, respectively (see Note 17).

## k. Fair Value of Financial Instruments

The Company determines the fair market values of its financial instruments based on the fair value hierarchy established by the Fair Value Measurements and Disclosures accounting guidance, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

## 1. Revenue Recognition and Accounts Receivable

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease agreements, which are generally five years. Receivables recorded related to the straight-lining of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets.



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Site development projects in which the Company performs consulting services include contracts on a time and materials basis or a fixed price basis. Time and materials based contracts are billed at contractual rates as the services are rendered. For those site development contracts in which the Company performs work on a fixed price basis, site development billing (and revenue recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of each phase on a per site basis, the Company recognizes the revenue related to that phase. Site development projects generally take from 3 to 12 months to complete.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management's estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset "costs and estimated earnings in excess of billings on uncompleted contracts" represents expenses incurred and revenues recognized in excess of amounts billed. The liability "billings in excess of costs and estimated earnings on uncompleted contracts," included within other current liabilities on the Company's Consolidated Balance Sheets, represents billings in excess of revenues recognized. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

The Company performs periodic credit evaluations of its customers. The Company monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon historical experience, specific customer collection issues identified and past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from customers on a case by case basis in accordance with the terms of the respective contracts or agreements with those customers. Amounts determined to be uncollectible are written off against the allowance for doubtful accounts in the period in which uncollectibility is determined to be probable.

The following is a rollforward of the allowance for doubtful accounts for the years ended December 31, 2010, 2009, and 2008;

<table><tr><td rowspan="3"></td><td colspan="5">For the year ended December 31,</td></tr><tr><td>2010</td><td colspan="2">2009</td><td colspan="2">2008</td></tr><tr><td colspan="5">(in thousands)</td></tr><tr><td>Beginning balance</td><td>$     350</td><td>$     852</td><td>$     1,186</td><td></td><td></td></tr><tr><td>Allowance recorded relating to acquisitions</td><td>-</td><td>10</td><td>-</td><td></td><td></td></tr><tr><td>Provision (credits) for doubtful accounts</td><td>630</td><td>465</td><td>(81)</td><td></td><td></td></tr><tr><td>Write-offs, net of recoveries</td><td>(717)</td><td>(977)</td><td>(253)</td><td></td><td></td></tr><tr><td>Ending balance</td><td>$     263</td><td>$     350</td><td>$     852</td><td></td><td></td></tr></table>

## m. Cost of Revenue

Cost of site leasing revenue includes ground lease rent, property taxes, maintenance (exclusive of employee related costs) and other tower operating expenses. Liabilities recorded related to the straight-lining of ground leases are reflected in other long-term liabilities on the Consolidated Balance Sheets. Cost of site development revenue includes the cost of materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly related to the projects. All costs related to site development projects are recognized as incurred. All rental obligations due to be paid out over the minimum lease term, including fixed escalations, are recorded on a straight-line basis over the minimum lease term.



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## n. Income Taxes

The Company had taxable losses during the years ended December 31, 2010, 2009 and 2008, and as a result, net operating loss carry-forwards have been generated. The majority of these net operating loss carry-forwards are fully reserved as management believes it is not “more-likely-than-not” that the Company will generate sufficient taxable income in future periods to recognize the losses. The tax years 1997 through 2010 remain open to examination by the major jurisdictions in which the Company operates.

The Company determines whether it is “more-likely-than-not” that a tax position taken in an income tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. The Company has not identified any tax exposures that require adjustment. In the future, to the extent that the Company records unrecognized tax exposures, any related interest and penalties will be recognized as interest expense in the Company’s Consolidated Statements of Operations.

The Company does not calculate U.S. taxes on undistributed earnings of foreign subsidiaries because substantially all such earnings are expected to be reinvested indefinitely.

## o. Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors, including stock options, restricted stock units and employee stock purchases under employee stock purchase plans. The Company records compensation expense, net of estimated forfeitures, for stock options and restricted stock units on a straight-line basis over the vesting period. Compensation expense for employee stock options is based on the estimated fair value of the options on the date of the grant using the Black-Scholes option-pricing model. The stock options granted to non-employees are valued using the Black-Scholes option-pricing model based on the market price of the underlying common stock on the “valuation date,” which for options to non-employees is the vesting date. Expense related to the options granted to non-employees is recognized on a straight-line basis over the shorter of the period over which services are to be received or the vesting period. Compensation expense for restricted stock units is based on the fair market value of the units awarded at the date of the grant.

## p. Asset Retirement Obligations

The Company recognizes asset retirement obligations in the period in which they are incurred, if a reasonable estimate of a fair value can be made, and accretes such liability through the obligation’s estimated settlement date. The associated asset retirement costs are capitalized as part of the carrying amount of the related tower fixed assets, and over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the estimated useful life of the tower.

The Company has entered into ground leases for the land underlying the majority of the Company’s towers. A majority of these leases require the Company to restore leaseholds to their original condition upon termination of the ground lease. The asset retirement obligation at December 31, 2010 and December 31, 2009 was $5.2 million and $4.6 million, respectively, and is included in other long-term liabilities on the Consolidated Balance Sheets. Upon settlement of the obligations, any difference between the cost to retire an asset and the recorded liability is recorded in the Consolidated Statements of Operations as a gain or loss. In determining the impact of the asset retirement obligations, the Company considered the nature and scope of the contractual restoration obligations contained in the Company’s third party ground leases, the historical retirement experience as an indicator of future restoration probabilities, intent in renewing existing ground leases through lease termination dates, current



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

## q. Loss Per Share

The Company has potential common stock equivalents related to its outstanding stock options and convertible senior notes. These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive in calculating the full year earnings per share. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computations are the same for all periods presented in the Consolidated Statements of Operations.

## r. Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is comprised of net income (loss) and “other comprehensive income (loss).” Comprehensive income (loss) is presented in the Consolidated Statements of Shareholders’ Equity.

## s. Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through other comprehensive loss in shareholders' equity.

## t. Reclassifications

Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

## 3. CURRENT ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2010-06, Improving Disclosures about Fair Value Measurements (“ASU 2010-06”) which requires new disclosures about recurring or nonrecurring fair-value measurements including significant transfers into and out of Level 1 and Level 2 fair value measurements and information on purchases, sales, issuances, and settlements on a gross basis in the reconciliation of Level 3 fair value measurements. The FASB also clarified existing fair value measurement disclosure guidance about the level of disaggregation, inputs, and valuation techniques. ASU 2010-



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

06 is effective for fiscal years beginning after December 15, 2009. The adoption of this accounting guidance did not have any impact on the Company’s disclosures.

In February 2010, the FASB issued ASU 2010-09, Amendments to Certain Recognition and Disclosure Requirements. ASU 2010-09 updates ASC Topic 855, Subsequent Events. ASU 2010-09 removes the requirement to disclose the date through which an entity has evaluated subsequent events. The Company adopted the provisions of ASU 2010-09 upon issuance with no material impact to the Company’s financial position or results of operations.

## 4. FAIR VALUE OF FINANCIAL INSTRUMENTS

Items Measured at Fair Value on a Recurring Basis— The carrying values of the Company's financial instruments that approximate fair value due to the short maturity of those instruments primarily includes cash and cash equivalents, short-term investments, restricted cash, accounts receivable, and accounts payable. These financial instruments are valued using Level 1 inputs. Level 1 valuations rely on quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Long-term investments which are included in other assets on the Company’s Consolidated Balance Sheet consist of U.S. treasuries, corporate bonds and preferred securities (formerly auction rate securities) (see Note 2 for additional information).

During the year ended December 31, 2010 and 2009, there were no changes in the fair value of the preferred securities (formerly auction rate securities). The Company recorded $13.3 million of other-than-temporary impairment charges in other income (expense) on its Consolidated Statements of Operations for the year ended December 31, 2008. The Company determined the other-than-temporary impairment charge for the year ended December 31, 2008 based on a variety of factors, including the significant decline in fair value indicated for the individual investments, the adverse market conditions impacting preferred securities (formerly auction rate securities) and the exercise of the put rights that resulted in the Company owning shares of FGIC Preferred Stock and shares of Ambac Preferred Stock.

The Company has estimated the fair value of these preferred securities (formerly auction rate securities) utilizing a Level 3 valuation methodology. Level 3 valuations rely on unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The assumptions used in the valuation included the ultimate time horizon over which dividends are anticipated to be paid on the preferred stock, the coupon rate for these securities, and the appropriate discount margins. The Company continues to monitor market and other conditions in assessing whether further changes in the fair value of these securities are warranted. These estimated fair values could change based on future market conditions and as such, the Company may be required to record additional unrealized losses for impairment if the Company determines there are further declines in their fair value.

A reconciliation of the beginning and ending balances for the preferred securities (formerly auction rate securities) that use significant unobservable inputs (Level 3) as of December 31, 2010 and 2009 is as follows:

Items Measured at Fair Value on a Nonrecurring Basis—The Company’s long-lived assets (see Note 2), intangibles, asset retirement obligations (see Note 2) and earnouts related to acquisitions (see Note 6) are measured at fair value on a nonrecurring basis using Level 3 inputs. The fair value of the long-lived assets, intangibles and asset retirement obligations is calculated using a discounted cash flow model. The fair value of the earnouts is based on the anticipated future earnout obligations. The Company recorded an impairment charge of $5.9 million, $3.9 million and $0.9 million for the twelve months ended December 31, 2010, 2009 and 2008, respectively (see Note 17).

Fair Value of Financial Instruments— The carrying value of the Company’s financial instruments, with the exception of long-term debt including current portion, reasonably estimate the related fair values as of December 31, 2010 and December 31, 2009.

The Company determines fair value of its debt instruments utilizing various sources including quoted prices and indicative quotes (that is non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices. The following table reflects fair values, principal values and carrying values of the Company’s debt instruments (see Note 12).

## 5. RESTRICTED CASH

Restricted cash consists of the following:

<table><tr><td></td><td>As of December 31, 2010</td><td>As of December 31, 2009</td><td>Included on Balance Sheet</td></tr><tr><td></td><td colspan="3">(in thousands)</td></tr><tr><td>Securitization escrow accounts</td><td>$     28,583</td><td>$     29,108</td><td>Restricted cash - current asset</td></tr><tr><td>Payment and performance bonds</td><td>873</td><td>1,177</td><td>Restricted cash - current asset</td></tr><tr><td>Surety bonds and workers compensation</td><td>11,392</td><td>11,097</td><td>Other assets - noncurrent</td></tr><tr><td>Total restricted cash</td><td>$     40,848</td><td>$     41,382</td><td></td></tr></table>

Pursuant to the terms of the Mortgage Pass-Through Certificates Series 2006-1 (the "2006 CMBS Certificates") and, upon their refinancing, pursuant to the terms of the Secured Tower Revenue Securities Series 2010-1 (the "2010-1 Tower Securities") and the Secured Tower Revenue Securities Series 2010-2 (the "2010-2 Tower Securities" and together with the 2010-1 Tower Securities, the "2010 Tower Securities") (see Note 12), the Company is required to establish a controlled deposit account, held by the indenture trustee, into which all rents and other sums due on the towers that secured the 2006 CMBS Certificates and those that currently secure the 2010 Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes and insurance premiums related to tower sites, (3) trustee and servicing expenses, (4) management fees, and (5) to reserve a portion of advance rents from tenants. The restricted cash in the controlled deposit account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 12) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no Event of Default has occurred. All monies held by the indenture trustee are classified as restricted cash on the Company’s Consolidated Balance Sheets.

Securitization escrow accounts relate to funds that are required to be in escrow, initially pursuant to the terms of the 2006 CMBS Certificates and, upon their refinancing, pursuant to the terms of the 2010 Tower Securities. Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily related to the Company’s tower removal obligations. As of December 31, 2010, the Company had $19.7 million in surety, payment and performance bonds for which it is only required to post $9.6 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements. As of December 31, 2010 and 2009, the Company had pledged $2.2 million and $2.4 million, respectively, as collateral related to its workers compensation policy. Restricted cash for surety bonds and workers compensation are included in other assets on the Company’s Consolidated Balance Sheets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

applicable closing date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed by major balance sheet caption, as well as the separate recognition of intangible assets from goodwill if certain criteria are met. These intangible assets represent the value associated with current leases in place at the acquisition date (“Current contract intangibles”) and future tenant leases anticipated to be added to the acquired towers (“Network location intangibles”) and were calculated using the discounted values of the current or future expected cash flows. The intangible assets are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years.

From time to time, the Company agrees to pay additional consideration (or earnouts) in connection with its acquisitions if the towers or businesses that are acquired meet or exceed certain performance targets in the one to three years after they have been acquired. The Company records contingent consideration for acquisitions that occurred prior to January 1, 2009 when the contingent consideration is paid. Effective January 1, 2009, the Company accrues for contingent consideration in connection with acquisitions at fair value as of the date of the acquisition. All subsequent changes in fair value are recorded through the Consolidated Statements of Operations. In certain acquisitions, the additional consideration may be paid in cash or shares of Class A common stock at the Company’s option.

For the years ended December 31, 2010 and 2009, certain earnings targets associated with the acquired towers were achieved, and therefore, the Company paid in cash $8.7 million and $3.4 million, respectively. For the year ended December 31, 2009, the Company issued approximately 78,000 shares of Class A common stock as a result of acquired towers exceeding certain performance targets. As of December 31, 2010, the Company’s estimate of its potential obligation if the performance targets contained in various acquisition agreements were met was $3.3 million which the Company recorded in accrued expenses. The maximum potential obligation related to the performance targets was $7.9 million as of December 31, 2010. These obligations are associated with new build and tower acquisition programs within the Company’s site leasing segment.

Subsequent to December 31, 2010, the Company acquired 123 towers from third party sellers in exchange for $63.6 million in cash.

## 10. CONCENTRATION OF CREDIT RISK

The Company’s credit risks consist primarily of accounts receivable with national, regional and local wireless service providers and federal and state government agencies. The Company performs periodic credit evaluations of its customers’ financial condition and provides allowances for doubtful accounts, as required, based upon factors surrounding the credit risk of specific customers, historical trends and other information. The Company generally does not require collateral.

## The CMBS Certificates

## Commercial Mortgage Pass-Through Certificates, Series 2005-1

On November 18, 2005, a New York common law trust (the “Trust”), formed by an indirect subsidiary of the Company, issued in a private transaction, $405.0 million of 2005 CMBS Certificates, Series 2005-1 (the “2005 CMBS Certificates”).”

The 2005 CMBS Certificates consisted of five classes with annual pass-through interest rates ranging from 5.369% to 6.706%. The weighted average annual fixed coupon interest rate of the 2005 CMBS Certificates was 5.6%, payable monthly, and the effective weighted average annual fixed interest rate was 4.8%, after giving effect to the settlement of two interest rate swap agreements entered into in contemplation of the transaction (see Note 13).

On July 28, 2009, the Company repaid the remaining principal balance of $380.2 million of the 2005 CMBS Certificates and paid $10.1 million for related prepayment consideration plus accrued interest and fees. During the year ended December 31, 2009, but prior to the payoff of the principal balance, the Company repurchased an aggregate of $18.6 million, in principal amount of 2005 CMBS Certificates for $16.6 million in cash. The Company recorded in its Consolidated Statements of Operations a $7.2 million net loss on the early extinguishment of debt for the year ended December 31, 2009. During 2008, the Company repurchased an

aggregate of $6.2 million in principal amount of the 2005 CMBS Certificates for $5.5 million in cash. The Company recorded in its Consolidated Statements of Operations a $0.7 million gain on early extinguishment of debt for the year ended December 31, 2008.

## Commercial Mortgage Pass-Through Certificates Series 2006-1

On November 6, 2006, the Trust issued in a private transaction $1.15 billion of 2006 CMBS Certificates. The 2006 CMBS Certificates consisted of nine subclasses with annual pass-through interest rates ranging from 5.314% to 7.825%. The weighted average annual fixed coupon interest rate of the 2006 CMBS Certificates was 5.9%, payable monthly, and the effective weighted average annual fixed interest rate was 6.2% after giving effect to the settlement of the nine interest rate swap agreements entered into in contemplation of the transaction (see Note 13).

On April 16, 2010, the Company repaid the remaining principal balance of $938.6 million of the 2006 CMBS Certificates and paid $38.5 million for prepayment consideration plus accrued interest and fees. During the year-to-date period ended December 31, 2010, but prior to the payoff of the principal balance, the Company repurchased an aggregate of $2.0 million in principal amount of 2006 CMBS Certificates for $2.1 million in cash. The Company recorded on the Company’s Consolidated Statements of Operations a $49.0 million loss on extinguishment of debt related to the repurchases and prepayment during the year ended December 31, 2010.

During the year ended 2009, the Company repurchased an aggregate of $150.1 million in principal amount of 2006 CMBS Certificates for $150.5 million in cash. The Company recorded in its Consolidated Statements of Operations a $2.7 million loss on the early extinguishment of debt for the year ended December 31, 2009. During 2008, the Company repurchased an aggregate of $59.3 million in principal amount of 2006 CMBS Certificates for $39.8 million in cash and recorded in its Consolidated Statements of Operations a $18.2 million gain on early extinguishment of debt for the year ended December 31, 2008.

During the year ended December 31, 2010, 2009 and 2008, the Company incurred $16.4 million, $74.6 million and $91.8 million of interest expense related to the 2005 CMBS Certificates and 2006 CMBS Certificates, respectively.

## Secured Tower Revenue Securities Series 2010

On April 16, 2010, the Trust issued $680.0 million of 2010-1 Tower Securities and $550.0 million of 2010-2 Tower Securities. The 2010-1 Tower Securities have an annual interest rate of 4.254% and the 2010-2 Tower Securities have an annual interest rate of 5.101%. The weighted average annual fixed coupon interest rate of the 2010 Tower Securities is 4.6%, payable monthly. The anticipated repayment date and the final maturity date for the 2010–1 Tower Securities is April 16, 2015 and April 16, 2040, respectively. The anticipated repayment date and the final maturity date for the 2010–2 Tower Securities is April 16, 2017 and April 16, 2042, respectively. The Company incurred deferred financing fees of approximately $17.8 million in relation to this transaction which are being amortized through the anticipated repayment date of each of the 2010 Tower Securities. Net proceeds from the 2010 Tower Securities were used to repay in full the outstanding 2006 CMBS Certificates in the amount of $938.6 million and pay the related prepayment consideration plus accrued interest and fees. The remaining net proceeds were used for general corporate purposes.

The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of SBA Properties, Inc., SBA Sites, Inc., and SBA Structures, Inc., indirect wholly-owned operating subsidiaries of the Company (the "Borrowers"). The Borrowers are special purpose vehicles which exist solely to hold the towers which are subject to the securitization. In connection with the issuance of the 2010 Tower Securities and the repayment of the 2006 CMBS Certificates, the mortgage loan components relating to the 2006 CMBS Certificates were repaid and the



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

mortgage loan was amended to create two new loan components, each with terms that are identical to the series of 2010 Tower Securities to which it relates. The Borrowers are jointly and severally liable for all obligations under the mortgage loan.

The mortgage loan underlying the 2010 Tower Securities will be paid from the operating cash flows from the aggregate 3,683 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust and deeds to secure debt on a substantial portion of the tower sites, (ii) a security interest in substantially all of the Borrowers' personal property and fixtures, (iii) the Borrowers' rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., the Company's indirect subsidiary, is entitled to receive a management fee equal to 7.5% of the Borrowers' operating revenues for the immediately preceding calendar month.

The Borrowers may prepay either of the mortgage loan components, in whole or in part, with no prepayment consideration, (i) within nine months of the anticipated repayment date of such mortgage loan component, (ii) with proceeds received as a result of any condemnation or casualty of any tower site owned by the Borrowers or (iii) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of 2010 Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of prepayment to and including the first due date that is nine months prior to the anticipated repayment date over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the 2010 Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any, by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the 2010 Tower Securities, all rents and other sums due on any of the tower sites owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as restricted cash on the Company’s Consolidated Balance Sheets (see Note 5). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of December 31, 2010, the Borrowers met the required Debt Service Coverage Ratio and were in compliance with all other covenants.

The Company incurred cash interest expense of $40.7 million during the year ended December 31, 2010 related to the 2010 Tower Securities.

## 0.375% Convertible Senior Notes due 2010

On March 26, 2007, the Company issued $350.0 million of its 0.375% Convertible Senior Notes (the “0.375% Notes”). Interest was payable semi-annually on June 1 and December 1. The 0.375% Notes had a maturity date of December 1, 2010.

On October 5, 2010, the Company provided notice to the trustee and holders of its 0.375% Notes that the Company had elected to settle 100% of its conversion obligation relating to the 0.375% Notes in cash.

Pursuant to the terms of the Indenture, on or prior to November 26, 2010, the Company received conversion notices from holders of an aggregate of $30.3 million in principal of our 0.375% Notes. Pursuant to Section 10.02 of the Indenture, these notes were converted at a price of $1,152.78 per $1,000 of principal or an aggregate of $34.9 million. Concurrently with the settlement of the Company's conversion obligation, the Company settled two convertible note hedge transactions that the Company had initially purchased at the time the 0.375% Notes were issued. In connection with the settlement of these options, the Company received an aggregate of $13.1 million (including $8.5 million attributable to a portion held by a wholly-owned subsidiary of the Company). The remaining $120,000 aggregate principal amount of 0.375% Notes that was not earlier converted or repurchased matured on December 1, 2010. On December 1, 2010, the Company satisfied its obligation on the notes held to maturity by paying $120,000 in cash plus accrued interest.

During the year ended December 31, 2009, the Company consummated privately negotiated exchanges of the 0.375% Notes for Class A common stock in reliance on Section 3(a)(9) of the Securities Act of 1933, as amended. Pursuant to these exchanges, the Company issued approximately 618,000 shares of the Company’s Class A common stock in exchange for $12.5 million in principal amount of 0.375% Notes. In addition, the Company also repurchased an aggregate of $95.2 million in principal amount of 0.375% Notes for $90.6 million in cash. The Company recorded a gain on the early extinguishment of debt of $6.1 million and a net reduction to additional paid in capital of $0.6 million related to these transactions.

During the year ended December 31, 2008, the Company consummated privately negotiated exchanges of the 0.375% Notes for Class A common stock in reliance on Section 3(a)(9) of the Securities Act of 1933, as amended. During the fourth quarter of 2008, the Company issued approximately 3,407,914 shares of the Company’s Class A common stock in exchange for $73.8 million in principal amount of 0.375% Notes. In addition, the Company also repurchased an aggregate of $138.1 million in principal amount of 0.375% Notes for $102.5 million in cash. The Company recorded a gain on the early extinguishment of debt of $25.7 million and a net increase to additional paid in capital of $54.3 million related to these transactions.

In April 2009, the Company also terminated the portion of the convertible note hedge and warrant transactions that it entered into in March 2007 with respect to its 0.375% Notes which related to the $264.1 million principal amount of 0.375% Notes that the Company previously repurchased for cash or stock. The Company received a net settlement of approximately 546,000 shares from the counterparties of the hedge and warrant transactions.

The Company was amortizing the debt discount on the 0.375% Notes utilizing the effective interest method over the life of the 0.375% Notes which increased the effective interest rate of the 0.375% Notes from its coupon rate of 0.375% to 6.9%. The Company incurred cash interest expense of $0.05 million, $0.2 million and $1.2 million for the years ended December 31, 2010, 2009 and 2008, respectively. The Company recorded non-cash

interest expense of $1.8 million, $3.7 million and $17.2 million for the years ended December 31, 2010, 2009 and 2008, respectively.

## 1.875% Convertible Senior Notes due 2013

On May 16, 2008, the Company issued $550.0 million of its 1.875% Convertible Senior Notes (the “1.875% Notes”). Interest is payable semi-annually on May 1 and November 1. The 1.875% Notes have a maturity date of May 1, 2013. The Company incurred fees of $12.9 million with the issuance of the 1.875% Notes of which $9.1 million was recorded as deferred financing fees and $3.8 million was recorded as a reduction of shareholders’ equity.

The 1.875% Notes are convertible, at the holder’s option, into shares of the Company’s Class A common stock, at an initial conversion rate of 24.1196 shares of Class A common stock per $1,000 principal amount of 1.875% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $41.46 per share or a 20% conversion premium based on the last reported sale price of $34.55 per share of Class A common stock on the Nasdaq Global Select Market on May 12, 2008, the purchase agreement date. The 1.875% Notes are convertible only under the following certain circumstances: (1) during any calendar quarter commencing at any time after June 30, 2008 and only during such calendar quarter, if the last reported sale price of the Company’s Class A common stock for at least 20 trading days during the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the applicable conversion price per share of the Company’s Class A common stock on the last trading day of such preceding calendar quarter, (2) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of 1.875% Notes for each day in the measurement period was less than 95% of the product of the last reported sale price of the Company’s Class A common stock and the applicable conversion rate, (3) if specified distributions to holders of the Company’s Class A common stock are made or specified corporate transactions occur, and (4) at any time on or after February 19, 2013.

Upon conversion, the Company has the right to settle the conversion of each $1,000 principal amount of 1.875% Notes with any of the three following alternatives, at its option: delivery of (1) 24.1196 shares of the Company’s Class A common stock, (2) cash equal to the value of 24.1196 shares of the Company’s Class A common stock calculated at the market price per share of the Company’s Class A common stock at the time of conversion or (3) a combination of cash and shares of the Company’s Class A common stock.

The net proceeds from this offering were approximately $536.8 million after deducting discounts, commissions and expenses. A portion of the net proceeds from the sale of the 1.875% Notes was used to repurchase and retire approximately 3.47 million shares of Class A common stock, valued at $120.0 million based on the closing stock price of $34.55 on May 12, 2008. The repurchased shares were recorded as a reduction to Class A common stock for the par value of the Class A common stock as well as an increase to accumulated deficit on the Company’s Consolidated Balance Sheets.

Concurrently with the pricing of the 1.875% Notes, the Company entered into convertible note hedge transactions with affiliates of four of the initial purchasers of the 1.875% Notes. The initial strike price of the convertible note hedge transactions is $41.46 per share of the Company’s Class A common stock (the same as the initial conversion price of the 1.875% Notes) and is similarly subject to certain customary adjustments. The convertible note hedge transactions originally covered 13,265,780 shares of Class A common stock. The cost of the convertible note hedge transactions was $137.7 million. A portion of the net proceeds from the sale of the 1.875% Notes and the warrant transactions discussed below were used to pay for the cost of the convertible note hedge transactions. The cost of the convertible note hedge transactions was recorded as a reduction to additional paid-in capital on the Company’s Consolidated Balance Sheets.



## SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Separately and concurrently with entering into the convertible note hedge transactions, the Company entered into warrant transactions whereby the Company sold warrants to each of the hedge counterparties to acquire an aggregate of 13,265,780 shares of Class A common stock at an initial exercise price of $67.37 per share. The aggregate proceeds from the warrant transactions were $56.2 million. The proceeds from issuance of the warrants were recorded as an increase to additional paid-in capital on the Company’s Consolidated Balance Sheets.

One of the convertible note hedge transactions entered into in connection with the 1.875% Notes was with Lehman Brothers OTC Derivatives Inc. (“Lehman Derivatives”). The convertible note hedge transaction with Lehman Derivatives covers 55% of the 13,265,780 shares of the Company’s Class A common stock potentially issuable upon conversion of the 1.875% Notes. In October 2008, Lehman Derivatives filed a voluntary petition for protection under Chapter 11 of the United States Bankruptcy Code. The filing by Lehman Derivatives of a voluntary Chapter 11 bankruptcy petition constituted an “event of default” under the convertible note hedge transaction with Lehman Derivatives. As a result, on November 7, 2008 the Company terminated the convertible note hedge transaction with Lehman Derivatives. Based on information available to the Company, there is no indication, as of the date of filing this Form 10-K, that any party other than Lehman Derivatives would be unable to fulfill their obligations under the convertible note hedge transactions.

The net cost of the convertible note hedge transaction with Lehman Derivatives was recorded as an adjustment to additional paid in capital and therefore the “event of default” did not have any impact on the Company’s financial position or results of operations. However, the Company could incur significant costs to replace this hedge transaction if it elects to do so. If the Company does not elect to replace the convertible note hedge transaction, then the Company would be subject to potential dilution or additional cost (depending on if the note is settled with shares or cash) upon conversion of the 1.875% Notes, if on the date of conversion the per share market price of the Company’s Class A common stock exceeded the conversion price of $41.46.

The Company is amortizing the debt discount on the 1.875% Notes utilizing the effective interest method over the life of the 1.875% Notes which increases the effective interest rate of the 1.875% Notes from its coupon rate of 1.875% to 9.4%. The Company incurred cash interest expense of $10.3 million, $10.3 million and $6.5 million for each of the years ended December 31, 2010, 2009 and 2008, respectively and non-cash interest expense of $31.5 million, $28.7 million and $16.8 million for the years ended December 31, 2010, 2009 and 2008, respectively. As of December 31, 2010, the carrying amount of the equity component related to the 1.875% Notes was $159.2 million.

The 1.875% Notes are reflected in long-term debt in the Company’s Consolidated Balance Sheets at carrying value. The following table summarizes the balances for the 1.875% Notes:

<table><tr><td></td><td>As of December 31, 2010</td><td>As of December 31, 2009</td></tr><tr><td></td><td colspan="2">(in thousands)</td></tr><tr><td>Principal balance</td><td>$     550,000</td><td>$     550,000</td></tr><tr><td>Debt discount</td><td>(86,030)</td><td>(117,541)</td></tr><tr><td>Carrying value</td><td>$     463,970</td><td>$     432,459</td></tr></table>

## 4.0% Convertible Senior Notes due 2014

On April 24, 2009, the Company issued $500.0 million of its 4.0% Convertible Senior Notes (“4.0% Notes”) in a private placement transaction. Interest on the 4.0% Notes is payable semi-annually on April 1 and October 1. The maturity date of the 4.0% Notes is October 1, 2014. The Company incurred fees of $11.7 million with the



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

issuance of the 4.0% Notes of which $7.7 million was recorded as deferred financing fees and $4.0 million was recorded as a reduction to shareholders' equity.

The 4.0% Notes are convertible, at the holder's option, into shares of the Company's Class A common stock, at an initial conversion rate of 32.9164 shares of Class A common stock per $1,000 principal amount of 4.0% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $30.38 per share or a 22.5% conversion premium based on the last reported sale price of $24.80 per share of the Company's Class A common stock on the Nasdaq Global Select Market on April 20, 2009, the purchase agreement date. The 4.0% Notes are convertible only under the following circumstances: (1) during any calendar quarter commencing at any time after June 30, 2009 and only during such calendar quarter, if the last reported sale price of the Company's Class A common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last trading day of the preceding calendar quarter is more than 130% of the applicable conversion price per share of Class A common stock on the last day of such preceding calendar quarter; (2) during the five business day period after any 10 consecutive trading day period (the "measurement period") in which the trading price per $1,000 principal amount of notes for each day in the measurement period was less than 95% of the product of the last reported sale price of the Company's Class A common stock and the applicable conversion rate; (3) if specified distributions to holders of the Company's Class A common stock are made or specified corporate transactions occur; or (4) at any time on or after July 22, 2014. Upon conversion, the Company has the right to settle its conversion obligation in cash, shares of Class A common stock or a combination of cash and shares of its Class A common stock. From time to time, upon notice to the holders of the 4.0% Notes, the Company may change its election regarding the form of consideration that the Company will use to settle its conversion obligation; provided, however, that the Company is not permitted to change its settlement election after July 21, 2014.

The net proceeds of this offering were approximately $488.2 million after deducting discounts, commissions and expenses. Contemporaneously with the closing of the sale of the 4.0% Notes, a portion of the net proceeds from the sale of the 4.0% Notes was used to repurchase 2.0 million shares of the Company’s Class A common stock, valued at $50.0 million based on the closing stock price of $24.80 on April 20, 2009. These repurchased shares were immediately retired by the Company. The repurchased shares were recorded as a reduction to Class A common stock for the par value of the Class A common stock as well as an increase to accumulated deficit.

Concurrently with the pricing of the 4.0% Notes, the Company entered into convertible note hedge transactions whereby the Company purchased from affiliates of certain of the initial purchasers of the 4.0% Notes an option covering 16,458,196 shares of its Class A common stock at an initial strike price of $30.38 per share (the same as the initial conversion price of the notes). Separately and concurrently with the pricing of the 4.0% Notes, the Company entered into warrant transactions whereby it sold to affiliates of certain of the initial purchasers of the 4.0% Notes warrants to acquire 16,458,196 shares of its Class A common stock at an initial price of $44.64 per share. The Company used approximately $61.6 million of the net proceeds from the 4.0% Notes offering plus the proceeds from the warrant transactions to fund the cost of the convertible note hedge transactions. The convertible note hedge transactions and the warrant transactions, taken as a whole, effectively increase the conversion price of the 4.0% Notes from $30.38 per share to $44.64 per share, reflecting a premium of 80% based on the closing stock price of $24.80 per share of the Company’s Class A common stock on April 20, 2009. If the market price of the Company’s Class A common stock exceeded the upper strike price of $44.64 per share on the conversion date of the 4.0% Notes, then the Company will be subject to dilution or cost upon conversion of the 4.0% Notes. The remaining net proceeds of $376.6 million were used for general corporate purposes, including repurchases or repayments of the Company’s outstanding debt.

The Company is amortizing the debt discount on the 4.0% Notes utilizing the effective interest method over the life of the 4.0% Notes which increases the effective interest rate of the 4.0% Notes from its coupon rate of

The Company incurred deferred financing fees of approximately $16.5 million in relation to this transaction which are being amortized through the anticipated repayment date of each of the Senior Notes. Net proceeds of this offering were $727.8 million after deducting expenses and the original issue discount.

Telecommunications used the net proceeds from this offering to repay the 2005 CMBS Certificates issued by its subsidiary and the related prepayment consideration, repay and terminate the Optasite Credit Facility and repay Senior Credit Facility and 0.375% Notes. The remaining net proceeds were used for general corporate purposes.

## 2010 Credit Facility

On February 11, 2010, SBA Senior Finance II, an indirect wholly-owned subsidiary of the Company, entered into a credit agreement for a $500.0 million senior secured revolving credit facility (the "2010 Credit Facility") with several banks and other financial institutions or entities from time to time parties to the credit agreement (the "Credit Agreement"). Amounts borrowed under the 2010 Credit Facility are secured by a first lien on the capital stock of Telecommunications, SBA Senior Finance, Inc. and SBA Senior Finance II, and substantially all of the assets, other than leasehold, easement or fee interests in real property, of SBA Senior Finance II and the Subsidiary Guarantors (as defined in the Credit Agreement). The Company incurred deferred financing fees of $4.9 million associated with the closing of this transaction. In addition, at the time of termination of the Senior Credit Facility, the remaining deferred financing fees balance of approximately $1.0 million was transferred to the 2010 Credit Facility in accordance with FASB accounting guidance for revolving credit facilities.

The 2010 Credit Facility consists of a revolving loan up to $500.0 million, based on SBA Senior Finance II’s ratio of Annualized Adjusted EBITDA to Consolidated Total Debt plus Net Hedge Exposure, may be borrowed, repaid and redrawn subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing, as set forth in the Credit Agreement. The Credit Agreement requires SBA Senior Finance II and the Company to maintain specific financial ratios, including, at the SBA Senior Finance II level, a ratio of Consolidated Total Debt to Annualized Borrower EBITDA (as defined in the Credit Agreement) that does not exceed 5.0x for any fiscal quarter, a ratio of Consolidated Total Debt and Net Hedge Exposure (as defined in the Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 5.0x for 30 consecutive days and a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (as defined in the Credit Agreement) of not less than 2.0x for any fiscal quarter. In addition, the Company’s ratio of Consolidated Total Net Debt to Consolidated Adjusted EBITDA (as defined in the Credit Agreement) for any fiscal quarter on an annualized basis cannot exceed 8.9x. The Credit Agreement also contains customary affirmative and negative covenants that, among other things, limit SBA Senior Finance II’s ability to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions or engage in certain asset dispositions, including a sale of all or substantially all of its assets. As of December 31, 2010, the



# SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Company and SBA Senior Finance II were in full compliance with the financial covenants contained in the 2010 Credit Facility.

Amounts borrowed under the 2010 Credit Facility accrue interest at the Eurodollar rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate (as defined in the Credit Agreement) plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (as defined in the Credit Agreement). A 0.375% to 0.5% per annum fee is charged on the amount of unused commitment. If it is not earlier terminated by SBA Senior Finance II, the 2010 Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, February 11, 2015. Proceeds available under the 2010 Credit Facility may be used for general corporate purposes.

As of December 31, 2010, the Company had $20.0 million outstanding under the 2010 Credit Facility and the weighted average interest rate for the amounts outstanding was 2.15%. As of December 31, 2010, the availability under the 2010 Credit Facility was $480.0 million. The Company may, from time to time, borrow from and repay the 2010 Credit Facility. Consequently, the amount outstanding under the 2010 Credit Facility at the end of a period may not be reflective of the total amounts outstanding during the period.

The 2010 Credit Facility also permits the Company to request that one or more lenders (1) increase their proportionate share of the 2010 Credit Facility commitment, up to an additional $200.0 million in the aggregate and (2) provide SBA Senior Finance II term loans for an aggregate amount up to $800.0 million, without requesting consent of the other lenders. SBA Senior Finance II's ability to request such increase of the 2010 Credit Facility or term loans is subject to its compliance with the conditions set forth in the Credit Agreement including, with respect to any term loan, compliance, on a pro forma basis, with the financial covenants and ratios set forth therein. Upon SBA Senior Finance II's request, each lender may decide, in its sole discretion, whether to increase all or a portion of its revolving credit facility commitment or whether to provide SBA Senior Finance II term loans and if so upon what terms.

The Company incurred cash interest expense of $1.7 million for the year ended December 31, 2010 relating to the 2010 Credit Facility.

## Senior Credit Facility

On January 18, 2008, SBA Senior Finance, an indirect wholly-owned subsidiary of the Company, entered into a Senior Credit Facility (the “Senior Credit Facility”) with several banks and other financial institutions or entities from time to time parties to the credit agreement.

Amounts borrowed under the facility accrued interest at the Eurodollar rate plus a margin that ranged from 150.0 basis points to 300.0 basis points or at a Base Rate (as defined in the Restated Credit Agreement) plus a margin that ranged from 50.0 basis points to 200.0 basis points, in each case based on the Consolidated Total Debt to Annualized Borrower EBITDA ratio (as defined in the Restated Credit Agreement and discussed below). A 0.5% per annum fee was charged on the amount of unused commitment.

During the year ended December 31, 2009, SBA Senior Finance borrowed $8.5 million and repaid $239.1 million under its Senior Credit Facility, which is presented within “Cash flows from financing activities” on the Company’s Consolidated Statements of Cash Flows.

## 2006 CMBS Certificate Swaps

During 2006, an indirect wholly-owned subsidiary of the Company entered into nine forward-starting swap agreements (the “2006 CMBS Certificate Swaps”) in anticipation of the 2006 CMBS Transaction. In October 2006, the Company terminated the 2006 CMBS Certificate Swaps in connection with entering into the purchase and sale agreement for the 2006 CMBS Certificates (see Note 12). The Company determined a portion of the swaps to be an effective cash flow hedge and as a result, recorded a deferred loss of $12.8 million in accumulated other comprehensive loss, net of applicable income taxes on the Company’s Consolidated Balance Sheets. The deferred loss is being amortized utilizing the effective interest method over the anticipated five year life of the 2006 CMBS Certificates and increases the effective interest rate on these certificates by 0.3%. On April 16, 2010, the Company wrote-off the remaining unamortized deferred loss of $3.6 million in connection with the repayment of the 2006 CMBS Certificates (see Note 12).

## 2005 CMBS Certificate Swaps

On June 22, 2005, an indirect wholly-owned subsidiary of the Company entered into two forward-starting interest rate swap agreements (the "2005 CMBS Certificate Swaps") in anticipation of the 2005 CMBS Transaction. On November 4, 2005, the Company entered into a purchase agreement regarding the purchase and sale of 2005 CMBS Certificates (see Note 12). In connection with this agreement, the Company terminated the 2005 CMBS Certificate Swaps. The Company determined the swaps to be an effective cash flow hedge and as a result, recorded a deferred gain of $14.8 million in accumulated other comprehensive loss, net of applicable income taxes on the Company's Consolidated Balance Sheets. The deferred gain was being amortized utilizing the effective interest method over the anticipated five year life of the 2005 CMBS Certificates and reduced the effective interest rate on these certificates by 0.8%. On July 28, 2009, the Company wrote-off the remaining unamortized net deferred gain of $3.9 million in connection with the repayment of the 2005 CMBS Certificates.

The Company recorded amortization of $1.7 million, and $3.0 million as an offset to non-cash interest expense on the Company’s Consolidated Statements of Operations for the years ended December 31, 2009 and 2008, respectively.

## 14. REDEEMABLE NONCONTROLLING INTERESTS

In connection with the Company’s business operations in Canada and Central America, the Company entered into agreements with non-affiliated joint venture partners that contain both a put option for its partners and a call option for the Company, requiring or allowing the Company, in certain circumstances, to purchase the remaining interest in such entity at a price based on predetermined earnings multiples. Each of these options is triggered upon the occurrence of specified events and/or upon the passage of time. The put rights may be exercised on varying dates causing the Company to purchase the applicable partner’s equity interests (the “Redemption Amount”) based on a formula defined in the respective joint venture agreements. None of these options are currently exercisable by either the Company or its partners. The noncontrolling interest is classified as a redeemable equity interest in mezzanine (or temporary equity) on the Company’s Consolidated Balance Sheets.

The Company allocates income and losses to the noncontrolling interest holder based on the applicable membership interest percentage. After applying those provisions, the Company calculates the redemption amount at each reporting period and records the amount, if any, by which the redemption amount exceeds the book value as a charge against income (loss) available to common shareholders. As of December 31, 2010 the redeemable noncontrolling interest presented on the Company’s Consolidated Balance Sheet represents the estimated fair value of the amount the Company could be required to pay to redeem the noncontrolling interest at the date of the exercise of either the put or the call option.

In December 2010, the Company acquired an additional 10% interest in the Central American joint venture for consideration of $7.5 million. This acquisition increased the Company’s ownership to 90% of the joint venture. As of December 2010, the 10% noncontrolling interest was valued at $12.5 million. In addition, the Company paid approximately $0.7 million in exchange for a 4.6% interest in a Canadian joint venture increasing the Company’s interest in that joint venture to 95.4%. The acquisition of the noncontrolling interest has been reflected as a reduction of additional-paid-in capital in accordance with ASC 810.

## 15. SHAREHOLDERS' EQUITY

## Common Stock equivalents

The Company has potential common stock equivalents related to its outstanding stock options (see Note 16), restricted stock units, the 1.875% Notes and the 4.0% Notes (see Note 12). These potential common stock

equivalents were not included in diluted loss per share because the effect would have been anti-dilutive for the years ended December 31, 2010, 2009 and 2008, respectively. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computation are the same for the years presented.

## Shareholder Rights Plan and Preferred Stock

During January 2002, the Company's Board of Directors adopted a shareholder rights plan and declared a dividend of one preferred stock purchase right for each outstanding share of the Company's common stock. Each of these rights which are currently not exercisable will entitle the holder to purchase one one-thousandth (1/1000) of a share of the Company's newly designated Series E Junior Participating Preferred Stock. In the event that any person or group acquires beneficial ownership of 15% or more of the outstanding shares of the Company's common stock or commences or announces an intention to commence a tender offer that would result in such person or group owning 15% or more of the Company's common stock, each holder of a right (other than the acquirer) will be entitled to receive, upon payment of the exercise price, a number of shares of common stock having a market value equal to two times the exercise price of the right. In order to retain flexibility and the ability to maximize shareholder value in the event of transactions that may arise in the future, the Board retains the power to redeem the rights for a set amount. The rights were distributed on January 25, 2002 and expire on January 10, 2012, unless earlier redeemed or exchanged or terminated in accordance with the Rights Agreement.

## Employee Stock Purchase Plan

In 1999, the Board of Directors of the Company adopted the 1999 Stock Purchase Plan (the “1999 Purchase Plan”). A total of 500,000 shares of Class A common stock were reserved for purchase under the 1999 Purchase Plan. During 2003, an amendment to the 1999 Purchase Plan was adopted which increased the number of shares reserved for purchase from 500,000 to 1,500,000 shares. In April 2009, the 1999 Plan expired and no shares were issued during 2009. During 2008, the Company adopted the 2008 Employee Stock Purchase Plan (“2008 Purchase Plan”) which reserved 500,000 shares of Class A common stock for purchase. The 2008 Purchase Plan permits eligible employee participants to purchase Class A common stock at a price per share which is equal to 85% of the fair market value of Class A common stock on the last day of an offering period.

For the year ended December 31, 2010, 34,597 shares of Class A common stock were issued under the 2008 Purchase Plan, which resulted in cash proceeds to the Company of approximately $1.1 million compared to the year ended December 31, 2009 when approximately 30,692 shares of Class A common stock were issued under the 2008 Purchase Plan, which resulted in cash proceeds to the Company of $0.7 million. At December 31, 2010, 434,711 shares remained available for issuance under the 2008 Purchase Plan. In addition, the Company recorded $0.2 million, $0.1 million and $0.2 million of non-cash compensation expense relating to the shares issued under the 2008 and 1999 Purchase Plans for each of the years ended December 31, 2010, 2009, and 2008, respectively.

## Non-Cash Compensation Expense

## 17. ASSET IMPAIRMENT

The Company evaluates its individual long-lived and related assets with finite lives for indicators of impairment to determine when an impairment analysis should be performed. The Company evaluates its tower assets and Current contract intangibles at the tower level, which is the lowest level for which identifiable cash flows exists. The Company evaluates its Network location intangibles for impairment at the tower leasing business level. The Company has established a policy to at least annually evaluate its tower assets and Current contract intangibles for impairment. In 2010, as a result of the annual impairment evaluation, the Company recorded a $5.9 million impairment charge on 59 towers and related assets that are not expected to achieve previously anticipated lease-up results. The amount of impairment was determined by using a discounted cash flow analysis which included estimates and assumptions such as general market and economic conditions,

historical operating results, geographic location, lease-up potential and expected timing of lease-up. In 2009, as a result of the annual impairment evaluation, the Company recorded a $2.0 million impairment charge on 21 towers and related assets that were not expected to achieve previously anticipated lease-up results. In addition, the Company recorded a $1.9 million impairment charge on its six DAS networks based on the estimated fair value of the DAS networks. The amount of impairment was determined by using a discounted cash flow analysis.

## 18. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS), NET

Accumulated other comprehensive income (loss), net has no impact on the Company’s net loss but is reflected in the Consolidated Balance Sheet through adjustments to shareholders’ equity. Accumulated other comprehensive income (loss), net derives from the amortization of deferred (gain) loss from settlement of derivative financial instruments relating to the CMBS Certificates issuance (see Note 12), the unfunded projected benefit obligation relating to the Company’s pension plan and the Company’s foreign currency translation adjustment. A rollforward of accumulated other comprehensive income (loss), net for the years ended December 31, 2010, 2009 and 2008 is as follows:

The Company has recorded a valuation allowance for deferred tax assets as management believes that it is not "more likely than not" that the Company will be able to generate sufficient taxable income in future periods to recognize the assets. The net change in the valuation allowance for the years ended December 31, 2010 and 2009 was $41.1 million and $52.1 million, respectively. Additionally, at December 31, 2010 the Company recorded a valuation allowance relating to federal and state tax credit carryovers of approximately $1.0 million and $0.4 million, respectively. These tax credits expire beginning 2017.

The Company has available at December 31, 2010, a net federal operating tax loss carry-forward of approximately $1.1 billion and an additional $109.4 million of net operating tax loss carry forward from stock options which will benefit additional paid-in capital when the loss is utilized. These net operating tax loss carry-forwards will expire between 2019 and 2030. The Internal Revenue Code places limitations upon the future availability of net operating losses based upon changes in the equity of the Company. If these occur, the ability of the Company to offset future income with existing net operating losses may be limited. In addition, the Company has available at December 31, 2010, a foreign net operating loss carry-forward of $6.0 million and a net state operating tax loss carry-forward of approximately $555.6 million. These net operating tax loss carry-forwards will expire between 2011 and 2030.

In accordance with the Company’s methodology for determining when stock option deductions are deemed realized, the Company utilizes a “with-and-without” approach that will result in a benefit not being recorded in APIC if the amount of available net operating loss carry-forwards generated from operations is sufficient to offset the current year taxable income.

## e. Contingent Purchase Obligations

From time to time, the Company agrees to pay additional consideration (or earmarks) for acquisitions if the towers or businesses that are acquired meet or exceed certain performance targets in the one to three years after they have been acquired. For the years ended December 31, 2010 and 2009, certain earnings targets associated with the acquired towers were achieved, and therefore, the Company paid in cash $8.7 million and $3.4 million, respectively. For the year ended December 31, 2009, the Company issued approximately 78,000 shares of Class A common stock as a result of acquired towers exceeding certain performance targets. As of December 31, 2010, the Company’s estimate of its potential obligation if the performance targets contained in various acquisition agreements were met was $3.3 million which the Company recorded in accrued expenses. The maximum potential obligation related to the performance targets was $7.9 million as of December 31, 2010. These obligations are associated with new build and tower acquisition programs within the Company’s site leasing segment. On certain acquisitions, at the Company’s option, additional consideration may be paid in cash or shares of Class A common stock.

In the fourth quarter of 2010, the Company recorded a $5.9 million impairment charge on 59 towers and related assets that are not expected to achieve previously anticipated lease-up results (see Note 17).

Basic and diluted net loss per share is computed by dividing net income by the weighted average number of shares for the period. Potentially dilutive have been excluded from the computation of diluted loss per share as their impact would have been anti-dilutive.

Because loss per share amounts are calculated using the weighted average number of common and dilutive common shares outstanding during each quarter, the sum of the per share amounts for the four quarters may not equal the total loss per share amounts for the year.

## Performance Graph

SBA’s Class A Common Stock began trading on The NASDAQ National Market on June 16, 1999 when its initial public offering commenced and is currently traded on the NASDAQ Global Select Market. The following graph shows the total return to the shareholders of an investment in SBA’s Class A Common Stock as compared to (i) an investment in the NASDAQ Composite Index; and (ii) an investment in a peer group made up of American Tower Corporation, Crown Castle International Corporation and Global Signal, Inc. \( ^{1} \)  (the “Peer Group”). The Peer Group was selected because it is a comprehensive peer group comprised of all of the comparable public companies in the business of owning and operating wireless communications towers, including companies that have emerged from bankruptcy proceedings.

Total shareholder return is determined by dividing (i) the sum of (A) the cumulative amount of dividends for a given period (assuming dividend reinvestment) and (B) the change in share price between the beginning and end of the measurement period, by (ii) the share price at the beginning of the measurement period.

## Non-GAAP Financial Measures Required Disclosures in Accordance with Regulation G

SBA Communications Corporation (“SBA” or “We”) often makes disclosures of non-GAAP financial measures, such as Tower Cash Flow and Tower Cash Flow Margin. Following is a reconciliation of these non-GAAP financial measures to their most comparable GAAP measures and the other information required by Regulation G. Additional non-GAAP financial measures, such as Adjusted EBITDA, Site Leasing Segment Operating Profit and Site Leasing Segment Operating Profit Margin which are included in this annual report are discussed and included in our 10-K which accompanies this annual report.

Tower Cash Flow is defined as Site Leasing Segment Operating Profit excluding non-cash straight-line leasing revenue and non-cash straight-line ground lease expense and Tower Cash Flow Margin is defined as Tower Cash Flow divided by the difference of site leasing revenue minus non-cash straight-line site leasing revenue. We discuss these non-GAAP financial measures because we believe these items are indicators of performance of our site leasing operations. In addition, Tower Cash Flow is a component of the calculation used by our lenders to determine compliance with certain covenants under our senior credit facility and senior notes. Neither Tower Cash Flow nor Tower Cash Flow Margin are intended to be alternative measures of site leasing gross profit nor of site leasing gross profit margin as determined in accordance with GAAP.

<table><tr><td>Site leasing revenue</td><td>$ 140,054</td></tr><tr><td>Non-cash straight-line leasing revenue</td><td>(1,516)</td></tr><tr><td>Site leasing revenue minus non-cash straight-line leasing revenue</td><td>$ 138,538</td></tr><tr><td>Tower Cash Flow</td><td>$ 111,231</td></tr><tr><td>Tower Cash Flow Margin</td><td>80.3%</td></tr></table>

## Special Note Regarding Forward-Looking Statements

This annual report contains forward-looking statements that concern expectations, beliefs, projections, strategies, anticipated events or trends including those concerning trends in the wireless industry, our ability to capitalize on such trends and our future operational and financial performance. These forward-looking statements are qualified in their entirety by cautionary statements and risk factor disclosures contained in our Form10-K filed with the Securities and Exchange Commission on February 25, 2010 and our quarterly earning press releases included as exhibits to our Form 8-K’s previously furnished to the Securities and Exchange Commission.
