                                  The Company

  We are a leading independent owner and operator of wireless communications
infrastructure in the United States. We generate revenues from our two primary
businesses -- site leasing and site development services. Since our founding in
1989, we have participated in the development of more than 12,000 antenna sites
in 49 of the 51 major wireless markets in the United States. In 1997, we began
aggressively expanding our site leasing business by capitalizing on our
nationally recognized site development experience and strong relationships with
wireless service providers to take advantage of the trend toward colocation and
independent tower ownership. As of April 30, 1999, we owned or controlled 642
towers, had 51 towers pending acquisition under letters of intent or definitive
agreements and had non-binding mandates to build over 400 additional towers for
anchor tenants. Our Annualized tower cash flow for the first quarter of 1999
was $11.1 million.

  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. We
lease antenna space on: (1) the towers we construct through build-to-suit
programs; (2) existing sites we acquire; (3) the towers we develop
strategically; and (4) sites we lease, sublease and/or manage for third
parties. Under a build-to-suit program, we build a tower for a wireless service
provider who has entered into a long-term anchor tenant lease. We also retain
ownership of the tower and the exclusive right to colocate additional tenants
on the tower. We believe that many wireless service providers are choosing the
build-to-suit option as an alternative to tower ownership and that this
outsourcing trend is likely to continue. We have also grown through selective
acquisitions from smaller independent tower owners. BellSouth Mobility DCS
recently awarded us a non-binding mandate to execute all of its outsourced 1999
new tower build-out, which is concentrated mainly in North Carolina, South
Carolina, eastern Tennessee and coastal Georgia. We expect this mandate to
involve approximately 150 new towers. We also recently were awarded a non-
binding mandate from Sprint PCS to build approximately 100 towers in Tennessee,
North Carolina, South Carolina and the Midwest.

  Our site development business consists of site development consulting and
site development construction. In our site development business, we provide a
full range of end-to-end services which typically occur in five phases: (1)
network pre-design; (2) communication site selection; (3) communication site
acquisition; (4) local zoning and permitting; and (5) site construction and
antenna installation. We have a diverse range of customers, including cellular,
personal communications service, or PCS, paging, specialized mobile radio, or
SMR, and enhanced specialized mobile radio, or ESMR, providers as well as other
users of wireless transmission and reception equipment. Our customers currently
include many of the major wireless communications companies, including AT&T
Wireless, BellSouth Mobility DCS, Nextel, Omnipoint, Pac Bell, PrimeCo,
Southwestern Bell and Sprint PCS. We have capitalized on our leadership
position in the site development business, our existing national field
organization and our strong relationships with wireless service providers to
develop our build-to-suit programs.

  We will continue to use our site development expertise to complement our site
leasing business and secure additional build-to-suit mandates. In 1998, we
built 310 towers. We believe that as the site development industry matures, our
revenues and gross profit from the consulting segment of that business will
continue to decline substantially. We also believe that, over the longer term,
our site leasing revenues will increase as carriers move to outsource ownership
and management of towers and as the number of towers we own or control grows as
a result.

                               Industry Overview

  We believe that the rapid growth in demand for wireless services will
continue to increase the need for communication sites (which include towers,
rooftops and other structures on which antennas are placed). The growth in
demand for wireless services and communication sites is the result of several
factors, including:

  .  the continuing build-out of higher frequency technologies, such as PCS,
     which have a reduced cell range and thus require a more dense network of
     towers;

  .  the need to expand services and fill-in and upgrade existing networks;

  .  business and consumer preferences for higher quality voice and data
     transmission;

  .  the emergence of new wireless technologies;

  .  decreasing costs of wireless services to consumers;

  .  increasing mobility of the U.S. population and the growing awareness of
     the benefits of mobile communications;

  .  favorable changes in telecommunications regulations; and

  .  the issuance of new wireless network licenses requiring the construction
     of new wireless networks.

  In addition, our site leasing business benefits from diversified recurring
revenue and effective operating leverage as a result of several factors,
including:

  .  the long-term nature of lease contract revenues;

  .  low customer churn rates due to the high direct and indirect costs of
     relocation;

  .  low variable operating costs, which cause increases in revenues to
     generate disproportionately larger increases in tower cash flow;

  .  low on-going maintenance capital expenditure requirements;

  .  a customer base diversified across geographic markets, industry segments
     (PCS, cellular, paging, ESMR and SMR) and individual customers within
     these segments; and

  .  the limited number of available tower sites serving a given area and
     consequent barriers to entry, principally as a result of local
     opposition to the proliferation of towers within such area.

  In 1995 the Personal Communications Industry Association, or PCIA, estimated
that the number of antenna sites in the United States for both cellular and PCS
providers would increase by an additional 100,000 antenna sites (more than one
of which can be located on a single communication site) over the subsequent ten
years as cellular systems expand coverage and PCS systems continue to be
deployed. We believe that wireless service providers face greater competition
today and are now focusing their capital and operations primarily on activities
that build subscriber growth, such as marketing and distribution. Therefore,
they will increasingly seek to outsource communication site ownership,
construction, management and maintenance.

                               Business Strategy

Our strategy is to lease antenna space to multiple tenants on towers that we
construct or acquire. We plan to enhance our position as a leading owner and
operator of communication sites. Key elements of our strategy include:

  .  Maximizing Use of Tower Capacity

  .  Developing New Towers That We Will Own and Operate

  .  Acquiring Existing Towers

  .  Building on Strong Relationships with Major Wireless Service Providers

  .  Maintaining our Expertise in Site Development Services

  .Capitalizing on Management Experience

                                 Recent Events

The Senior Credit Facility

  In the first quarter of 1999, SBA Telecommunications, Inc., our wholly-owned
subsidiary, entered into a $175.0 million senior credit facility. Our use of
the facility was limited to $125.0 million pending obtaining consents from the
holders of our senior discount notes. Borrowings under the senior credit
facility are being used to finance our business plan.

The Consent Solicitation

  On March 8, 1999, we concluded a consent solicitation whereby holders of
99.98% of our senior discount notes consented to amend a portion of the
indenture governing the notes, so that we would be permitted to borrow the full
$175.0 million under our senior credit facility. In exchange for the consent,
we offered holders an amount in cash equal to 1.25% of the accreted value, as
of March 1, 1999, of each note for which a consent was tendered.

The Com-Net Acquisition

  On April 30, 1999, we acquired Com-Net Construction Services, Inc.
Com-Net constructs towers and terminal switches on a turn-key basis for
wireless and other telecommunications companies, primarily through the
midwestern, eastern and western United States. Since its inception in 1990,
Com-Net has provided construction and other related services on over 2,000
tower sites, ranging from turn-key tower construction to the installation of
antennas. Clients of Com-Net include AT&T, BellSouth Cellular Corp., GTE and
Sprint. For the year ended December 31, 1998, Com-Net had revenues of over
$20.0 million and gross profit of $2.2 million. Dan Eldridge, the founder and
President of Com-Net, will continue as President of Com-Net subsequent to the
acquisition. We intend for Com-Net to continue to provide construction services
to wireless carriers and other telecommunications companies, and to build
towers for our ownership. At closing, we issued 780,000 shares of our Class A
common stock to the shareholders of Com-Net (480,000 of which were pledged to
us and will be returned to us if certain earnings targets are not met) and
assumed working capital debt of approximately $4.5 million. In addition, the
shareholders of Com-Net may receive up to $2.5 million in cash and 320,000
additional shares of Class A common stock if certain 1999 earnings targets are
met by the acquired entity, and up to an additional 400,000 shares of Class A
common stock if certain 2000 earnings targets are met.

  In connection with the Com-Net acquisition, we acquired an affiliate of Com-
Net that owns 15 completed towers located in Texas, Ohio and Tennessee and over
30 additional tower sites in various stages of development under build-to-suit
programs for a purchase price of $1.0 million in cash and assumed debt of
approximately $2.5 million.

                          Principal Executive Offices

  Our principal executive offices are located at One Town Center Road, Third
Floor, Boca Raton, Florida 33486, and our telephone number is (561) 995-7670.
We were founded in 1989 and incorporated in Florida in 1997.

                              the offering assuming the exercise of the over-
                              allotment option in full. See "Principal
                              Shareholders." We use the term "common stock" to
                              mean both of these classes.

                              Each class of common stock has the same rights to
Other rights................  dividends and upon liquidation. The Class B
                              common stock is convertible into Class A common
                              stock on a share-for-share basis. The Class B
                              common stock cannot be sold or transferred,
                              except (1) after conversion to Class A common
                              stock or (2) to certain categories of persons
                              specified in our articles of incorporation. The
                              Class B common stock automatically converts into
                              Class A common stock upon the occurrence of
                              certain events. See "Description of Capital
                              Stock--Class B Common Stock."

Use of proceeds.............
                              We estimate that the net proceeds to SBA from the
                              offering will be approximately $117.0 million. We
                              expect to use these proceeds to finance the
                              construction and acquisition of towers, for
                              general working capital purposes, to finance
                              future acquisitions of other tower companies or
                              related businesses, to pay outstanding dividends
                              on our Series A preferred stock, to redeem all
                              outstanding shares of our Series B preferred
                              stock and to repay revolving credit borrowings
- --------                      under our senior credit facility.

(a) Includes shares of Class A common stock to be issued to the holders of
    Series A preferred stock upon the automatic conversion of Series A
    preferred stock that will occur at the closing of the offering. Also
    includes all shares of Class A common stock issuable upon exercise of
    outstanding vested options or warrants having an exercise price below the
    initial public offering price. Does not include shares reserved for
    issuance upon exercise of unvested options or options that may be issued in
    the future pursuant to stock option plans. See "Management." Includes
    780,000 shares issued at the closing of the Com-Net acquisition, but does
    not include shares that may be issuable to the former shareholders of Com-
    Net if the agreed-upon 1999 and 2000 earnings targets are met.

(b) Reflects surrender of 351,518 shares of Class B common stock as of May 31,
    1999 to repay a shareholder note in the amount of approximately $3.8
    million.

                   Summary Unaudited Pro Forma Financial Data

  The following table presents our summary unaudited pro forma financial and
other data for the year ended December 31, 1998 and as of and for the three
months ended March 31, 1999. The pro forma summary operating data for the year
ended December 31, 1998 and the three months ended March 31, 1999 give effect
to the SBA pro forma transactions, which are (1) all individually immaterial
acquisitions completed during 1998 and the three months ended March 31, 1999
and (2) the issuance of Class A common stock and the application of the net
proceeds as described under "Use of Proceeds" as if each had occurred at the
beginning of the periods presented. The unaudited pro forma balance sheet data
as of March 31, 1999 have been prepared as if the issuance of Class A common
stock and the application of the net proceeds had occurred on that date. The
pro forma adjustments are based upon available information and certain
assumptions that we believe are reasonable. The pro forma financial data are
for informational purposes only and do not purport to present what our results
of operations or financial position would actually have been had these
transactions actually occurred on the date presented or to project our results
of operations or financial position at any future period. You should read the
information set forth below together with "Selected Historical Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the Consolidated Financial Statements and their related notes
included elsewhere in this prospectus.

(a) For the year ended December 31, 1995, selling, general and administrative
    expense includes cash compensation expense of $1.3 million representing the
    amount of officer compensation in excess of what would have been paid had
    the officer employment agreements entered into in 1997 been in effect
    during that period. For the year ended December 31, 1996, selling, general
    and administrative expense includes non-cash compensation expense of $7.0
    million incurred in connection with the consolidation of the predecessor
    companies and cash compensation expense of $4.9 million representing the
    amount of officer compensation in excess of what would have been paid had
    the officer employment agreements entered into in 1997 been in effect
    during that period. For the year ended December 31, 1997, selling, general
    and administrative expense includes non-cash compensation expense of $1.0
    million incurred in the consolidation of the predecessor companies. For the
    year ended December 31, 1998, selling, general and administrative expense
    includes non-cash compensation expense of $0.6 million incurred in
    connection with the issuance of stock options and Class A common stock.
(b) Selling, general and administrative expense includes corporate development
    expenses associated with our site leasing business that were incurred in
    connection with the acquisition or construction of owned towers. These
    expenses consist of compensation and overhead costs that are not directly
    related to the administration or management of existing towers. All of
    these costs are expensed as incurred. The amount of these corporate
    development expenses for the periods presented was as follows:

(c) Provision for income taxes represents a pro forma calculation (40%) for the
    years ended December 31, 1994, 1995 and 1996, when we were treated as an S
    Corporation under Subchapter S of the Internal Revenue Code of 1986, as
    amended. We converted to a C Corporation in 1997. Provision (benefit) for
    income taxes for the years ended December 31, 1997 and 1998 and for the
    three months ended March 31, 1998 and 1999 represents an actual provision
    (benefit). For 1997, the effective rate was in excess of the 40% rate used
    in the pro forma calculations due to the tax effect of our conversion to a
    C Corporation.

(d) EBITDA represents earnings before interest income, interest expense, other
    income, income taxes, depreciation and amortization. EBITDA is commonly
    used in the telecommunications industry to analyze companies on the basis
    of operating performance, leverage and liquidity. Adjusted EBITDA excludes
    the effect of the non-cash compensation expense referred to in footnote (a)
    above. Adjusted EBITDA is not intended to represent cash flows for the
    periods presented, nor has it been presented as an alternative to operating
    income or as an indicator of operating performance and should not be
    considered in isolation or as a substitute for measures of performance
    prepared in accordance with generally accepted accounting principles.
    Companies calculate Adjusted EBITDA differently and, therefore, Adjusted
    EBITDA as presented for us may not be comparable to Adjusted EBITDA
    reported by other companies. See our Consolidated Statements of Cash Flows
    in our Consolidated Financial Statements contained elsewhere in this
    prospectus.

(e) We define "tower cash flow" as site leasing revenue less cost of site
    leasing revenue (exclusive of depreciation). Tower cash flow includes
    deferred revenue attributable to certain leases. We believe tower cash flow
    is useful because it allows you to compare tower performance before the
    effect of expenses (selling, general and administrative) that do not relate
    directly to tower performance. We define "annualized tower cash flow" as
    tower cash flow for the last calendar quarter attributable to our site
    leasing business multiplied by four. Pro forma Annualized tower cash flow
    also includes the effect of fourth quarter acquisitions as if each had
    occurred at the beginning of the period presented.

(f) Total debt does not include amounts owed to the shareholder of $0.1 million
    and $10.7 million as of December 31, 1995 and 1996, respectively. These
    amounts were paid in March 1997.

                                  RISK FACTORS

  You should carefully consider the following risks as well as the other
information contained in this prospectus before investing in shares of our
Class A common stock.

  We expect the consulting segment of our site development revenues to decline
substantially as we continue to expand our site leasing business.

  Our growth strategy is primarily focused on expanding our site leasing
business, as opposed to our site development business. We believe that wireless
service providers have begun to move away from the traditional build-out
formula where those providers contract for site development services for a fee
and invest the capital necessary to build and own their own network of
communication towers. We believe that the use of build-to-suit programs is
rapidly becoming the preferred method of wireless network expansion. The
success of our site leasing business will depend on our ability to construct
and acquire towers and profitably manage the leasing of antenna sites on those
towers. In particular, the profitability of our site leasing business will
depend on our ability to construct and acquire towers and secure additional
tenants following initial tower construction or acquisition. We have only
limited experience in the site leasing business and we cannot assure you that
we will be successful in acquiring or constructing towers or securing
additional tenants in accordance with our business plan.

  As wireless service providers have moved away from the traditional build-out
formula, our site development revenue from the consulting segment declined in
fiscal 1997, fiscal 1998 and the first quarter of fiscal 1999, and we expect a
further substantial decline during the remainder of fiscal 1999. We expect this
trend to continue for the forseeable future as our customers continue to move
toward build-to-suit programs and other outsourcing alternatives and away from
wireless service provider-funded site development and ownership. However, you
should be aware that a substantial portion of our revenues has historically
come from the consulting segment of our site development business. In addition,
we anticipate that our operating expenses and cash needs will increase as we
continue to focus primarily on our site leasing business and the construction
and acquisition of tower assets.

  Our success in the site leasing business depends to a large extent on our
management's expectations and assumptions concerning future demand for
independently-owned communication sites and numerous other factors, many of
which are beyond our control. Any material error in any of these expectations
or assumptions could have a material adverse effect on our growth rate,
prospects, financial condition or results of operations. Because most of our
towers are newly constructed, and because these towers have little or no
positive cash flow at the time of their construction, the risks of lower tenant
demand for tower space are much greater for us than for a tower company which
has grown its portfolio by acquiring towers with existing cash flow. We cannot
assure you that we will be successful in growing our site leasing business.

The number of towers we build and our site development business revenues
fluctuate from quarter to quarter.

  The number of towers we build and the demand for our site development
services each fluctuates from period to period and within periods. Numerous
factors cause these fluctuations, including the timing of our customers'
capital expenditures, the number and significance of active customer
engagements during a quarter, delays incurred in connection with a project,
employee hiring, the use of consultants and the rate and volume of wireless
service providers' tower build-outs. While this demand fluctuates, we incur
significant fixed costs, such as maintaining a staff and office space in
anticipation of future contracts, even when there is no current business. The
timing of revenues is difficult to forecast as our sales cycle can be
relatively long and may depend on factors such as the size and scope of
assignments, budgetary cycles and pressures and general economic conditions.
Seasonal factors, such as weather, vacation days and total business days in a
quarter, and 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, may add to the variability of new tower builds and revenues and

                                       8
<PAGE>

could have a material adverse effect on our growth rate, prospects, financial
condition or results of operations. Consequently, the number of towers we build
and operating results of our site development business for any particular
period may vary significantly, and should not be considered as indicative of
longer-term results.

We face zoning and other restrictions on our ability to construct new towers.

  Our growth strategy depends on our ability to construct and operate towers in
a timely and cost-effective manner. A number of factors beyond our control,
including zoning and local permitting requirements, FAA considerations,
availability of tower components and construction equipment, skilled
construction personnel and bad weather conditions, can affect our ability to
construct new towers. In addition, as the concern over tower proliferation has
grown in recent years, certain communities have placed restrictions on new
tower construction or have delayed granting permits required for construction.
We cannot assure you (1) of the number of mandates that we will be awarded or
the number of mandates that will result in constructed towers; (2) that we will
be able to overcome regulatory or other barriers to new construction; (3) that
the number of towers planned for construction will be completed in accordance
with the requirements of our customers; or (4) that there will be a significant
need for the construction of new towers once existing wireless service
providers complete their tower network infrastructure build-out. Certain of our
anchor tenant leases contain penalty or forfeiture provisions in the event the
towers are not completed within specified time periods.

We face increasing competition for new tower opportunities and acquisitions of
existing towers.

  We compete for new tower opportunities primarily with site developers,
wireless carriers and other independent tower companies. We believe that
competition for new tower opportunities will increase and that additional
competitors will enter the tower market. Some of these additional competitors
have or are expected to have greater financial resources than we do.

  Our growth strategy also depends on our ability to acquire and operate
existing towers not built by us to augment our existing tower network. We
compete with other independent tower owners and operators for acquisitions of
towers, as well as site developers, and we expect that this competition will
increase. Increased competition for acquisitions may result in fewer
acquisition opportunities for us, as well as higher acquisition prices. We
regularly explore acquisition opportunities, and we are currently actively
negotiating to acquire additional towers. As of April 30, 1999, we had letters
of intent or definitive agreements with respect to the acquisition of 51
additional towers. We cannot assure you that we will be able to identify towers
or tower companies to acquire in the future on commercially reasonable terms or
at all. We may also face challenges in integrating newly acquired towers or
tower companies.

  We cannot assure you that we will be able to identify, finance and complete
future acquisitions on acceptable terms or that we will be able to profitably
manage and market available space on our towers. The extent to which we are
unable to construct or acquire additional towers, or profitably manage such
tower operations, may have a material adverse effect on our growth rate,
prospects, financial condition or results of operations.

  In addition, the timeframe for the current wireless build-out cycle may be
limited to the next few years, and many PCS networks have already been built
out in large markets. Our failure to move quickly and aggressively to obtain
growth capital and capitalize on this infrastructure opportunity could have a
material adverse effect on our growth rate, prospects, financial condition or
results of operations with respect to both site development services and site
leasing.

We will need to seek additional financing to fund our business plan.

  Our business strategy contemplates substantial capital expenditures in
connection with the expansion of our tower footprints by agreeing with wireless
carriers to assume ownership or control of their existing towers, by pursuing
build-to-suit opportunities and by exploring other tower acquisition
opportunities.

                                       9
<PAGE>


  We currently estimate that we will make at least $160.0 million of capital
expenditures in 1999 for the construction and acquisition of communication
sites, primarily towers, and the acquisition of Com-Net. Based on our current
operations and anticipated revenue growth, we believe that, if our business
strategy is successful, cash flow from operations and available cash, together
with the proceeds of the offering and available borrowings under our senior
credit facility, will be sufficient to fund our anticipated capital
expenditures through the end of 1999. Thereafter, however, or in the event we
exceed our currently anticipated capital expenditures by the end of 1999, or
are unable to fully draw on our senior credit facility, we anticipate that we
will need to seek additional equity or debt financing to fund our business
plan. We cannot assure you that additional financing will be available, on
commercially acceptable terms or at all, or that any additional debt financing
will be permitted by the terms of our existing indebtedness, including our
senior discount notes. Prior to March 1, 2003, interest expense on our
outstanding senior discount notes will consist solely of non-cash accretion of
original issue discount and the notes will not require cash interest payments.
After that time, our outstanding senior discount notes will have accreted to
$269.0 million and will require annual cash interest payments of approximately
$32.3 million. If we are required to issue additional common equity, it could
be dilutive to our existing equity investors. To the extent we are unable to
finance future capital expenditures, we will be unable to achieve our currently
contemplated business goals. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

The development of our site leasing business may strain our resources.

  Expanding our site leasing business may impose significant strains on our
management, operating systems and financial resources. In addition, we
anticipate that our operating expenses may increase from their 1998 levels as
we construct and acquire additional tower assets. Our failure to manage our
growth or unexpected difficulties encountered during expansion could have a
material adverse effect on our growth rate, prospects, financial condition or
results of operations. The pursuit and integration of new tower builds,
acquisitions, investments, joint ventures and strategic alliances will require
substantial attention from our senior management, which will limit the amount
of time available to devote to our existing operations.

  From January 1, 1995 to March 31, 1999, our work force increased from 82 to
320 employees. This growth has placed, and will likely continue to place, a
substantial strain on our administrative, operational and financial resources.
Our executive officers generally have had no experience in managing companies
this large. In addition, as part of our business strategy, we may acquire
complementary businesses or expand into new businesses. We cannot assure you
that we will be able to manage our growth successfully, or that our management,
personnel or operational and financial control systems will be adequate to
support expanded operations. Any such inabilities or inadequacies could have a
material adverse effect on our growth rate, prospects, financial condition or
results of operations.

We depend on demand for wireless communications for our revenues.

  Substantially all of our customers to date have been providers of wireless
communications services and, therefore, our success is dependent on their
success. Demand for our services is dependent on demand for communication sites
from wireless service providers, which, in turn, is dependent on the demand for
wireless services. Most types of wireless services currently require ground-
based network facilities, including communication sites for transmission and
reception. The extent to which wireless service providers lease these
communication sites depends on a number of factors beyond our control,
including the level of demand for wireless services, the financial condition
and access to capital of wireless service providers, the strategy of providers
with respect to owning or leasing communication sites, government licensing of
broadcast rights, changes in telecommunications regulations and general
economic conditions. In addition, wireless service providers frequently enter
into roaming agreements with competitors allowing them to use one another's
wireless communications facilities to accommodate customers who are out of
range of their home provider's services. These roaming agreements may be viewed
by wireless service providers as a superior alternative to leasing antenna
space on communications sites owned or controlled by us. The proliferation of
these roaming agreements could have a material adverse effect on our growth
rate, prospects, financial condition or results of operations.

                                       10
<PAGE>

  The wireless communications industry has grown significantly in recent years.
A slowdown in the growth of, or reduction in, demand in a particular wireless
segment could adversely affect the demand for communication sites. For example,
we anticipate that a significant amount of our revenues over the next several
years will be generated from providers in the PCS market and thus we will be
subject to downturns in PCS demand. Moreover, wireless service providers often
operate with substantial leverage, and financial problems for our customers
could result in accounts receivable going uncollected, in the loss of a
customer and the associated lease revenue, or in a reduced ability of these
customers to finance expansion activities.

We have many competitors for site leasing tenants.

  We compete for site leasing tenants with: (1) wireless service providers that
own and operate their own tower footprints and lease, or may in the future
decide to lease, antenna space to other providers; (2) site development
companies that acquire antenna space on existing towers for wireless service
providers, manage new tower construction and provide site development services;
(3) other large independent tower companies; and (4) smaller local independent
tower operators. Wireless service providers that own and operate their own
tower footprints generally are substantially larger and have greater financial
resources than we do. Several other independent companies also have larger
tower footprints and greater financial resources than we do. We believe that
tower location and capacity, price, quality of service and density within a
geographic market historically have been and will continue to be the most
significant competitive factors affecting the site leasing business. Because
most of our towers are newly constructed, and because these towers have little
or no positive cash flow at the time of their construction, the risks of lower
tenant demand for tower space are much greater for us than for a tower company
which has purchased most of its towers with existing cash flow.

Our mandates may not yield binding agreements.

  As of April 30, 1999, we had non-binding mandates to build over 400
additional towers under build-to-suit programs for wireless service providers.
Although we believe that the majority of these non-binding mandates will result
in long-term anchor leases for specific communication towers, there are a
number of steps that need to occur before any leases are executed. These steps
include, in some cases, finalization of build-out plans by the customers who
have awarded the mandates, completion of due diligence by us and our customers
and finalization of other definitive documents between the parties. As a
result, we cannot assure you as to the percentage of current and future non-
binding mandates that will ultimately result in binding anchor tenant leases
and constructed towers.

We depend on a small number of customers for most of our revenues.

  We derive a significant portion of our revenues from a small number of
customers. For example, during 1997 and 1998, our five largest customers
accounted for approximately 89.9% and 91.4%, respectively, of our revenues from
site development services. Four of the five largest site development customers
were also among our five largest customers overall in 1998. Sprint PCS, our
largest customer for the years ended December 31, 1997 and 1998, accounted for
53.6% and 41.3%, respectively, of our revenues from site development services
during those years. Other large customers include Pacific Bell Mobile Systems,
which accounted for 14.0% and 13.5% of our revenues from site development
services for the years ended December 31, 1997 and 1998, respectively, and
BellSouth Mobility DCS, which accounted for 23.8% of our revenues from site
development services for 1998. PageNet, our largest site leasing customer,
accounted for 33.4% of our site leasing revenue in 1998. 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 cannot assure you that
we will be successful in establishing relationships with new clients. Moreover,
we cannot assure you that our existing customers will continue to engage us for
additional projects. We have experienced and expect to continue to experience a
decline in overall demand for the consulting segment of our site development
services. The substantial majority of our existing non-binding mandates are
from BellSouth Mobility DCS and Sprint PCS. The loss of any significant
customer could have a material adverse effect on our growth rate, prospects,
financial condition or results of operations. See "Business--Customers."

Substantial Leverage--Our substantial indebtedness could adversely affect our
financial health and prevent us from fulfilling our payment obligations.

  We have a significant amount of indebtedness. The following chart shows
certain important credit information:
<TABLE>
<CAPTION>
                                                               At March 31,
                                                                   1999
                                                          ----------------------

      <S>                                                 <C>
      Total indebtedness.................................        $210,445
      Stockholders' equity (deficit).....................        $(35,141)
</TABLE>

  Our substantial indebtedness could have important consequences to you. For
example, it could:

  .  increase our vulnerability to general adverse economic and industry
     conditions;

  .  limit our ability to fund future working capital, capital expenditures,
     research and development costs and other general corporate requirements;

  .  require us to dedicate a substantial portion of our cash flow from
     operations to payments on our indebtedness, thereby reducing the
     availability of our cash flow to fund working capital, capital
     expenditures, research and development efforts and other general
     corporate purposes;

  .  limit our flexibility in planning for, or reacting to, changes in our
     business and the industry in which we operate;

  .  place us at a competitive disadvantage compared to our competitors that
     are less leveraged; and

  .  limit, along with the financial and other restrictive covenants in our
     indebtedness, among other things, our ability to borrow additional
     funds. And, failing to comply with those covenants could result in an
     event of default which, if not cured or waived, could have a material
     adverse effect on our growth rate, prospects, financial condition or
     results of operations.

  Our ability to service our debt obligations will depend on our future
operating performance, which will be affected by prevailing economic conditions
in the wireless communications industry, and financial, business and other
factors, certain of which are beyond our control. If we are unable to generate
sufficient cash flow from operations to service our indebtedness, we will be
forced to adopt an alternative strategy that may include actions such as
reducing, delaying or eliminating acquisitions, tower construction and other
capital expenditures, selling assets, restructuring or refinancing our
indebtedness or seeking additional equity capital. We cannot assure you that we
can effect any of these alternative strategies on satisfactory terms, if at
all. The implementation of any of these alternative strategies could have a
negative impact on the value of our Class A common stock.

  Our senior credit facility and the indenture governing our senior discount
notes each contains certain restrictive covenants. The senior credit facility
also requires us to maintain specified financial ratios and satisfy certain
financial condition tests. Our ability to meet these financial ratios and tests
can be affected by events beyond our control, and we cannot assure you that we
will be able to meet those tests. A breach of any of these covenants could
result in a default under the senior credit facility and the indenture
governing our senior discount notes. If an event of default should occur under
the senior credit facility, our lenders can elect to declare all amounts of
principal outstanding under the senior credit facility, together with all
accrued interest, to be immediately due and payable. This could also result in
the triggering of cross-default or cross-acceleration provisions in other
instruments, permitting acceleration of the maturity of additional
indebtedness. If we were unable to repay amounts that become due under the
senior credit facility, our lenders could proceed against the collateral
granted to them to secure that indebtedness. If the indebtedness under the
senior credit facility were to be accelerated, we cannot assure you that our
assets would be sufficient to repay in full such indebtedness. Substantially
all of our assets are pledged as security under the senior credit facility. See
"Description of Existing Debt."


                                       12
<PAGE>

  Our earnings have been insufficient to cover our fixed charges since the
issuance of our senior discount notes. We expect our earnings to continue to be
insufficient to cover our fixed charges for the foreseeable future. We may be
able to incur substantial additional indebtedness in the future. If new debt is
added to our current debt levels, the related risks that we face could
intensify.

We must comply with a variety of extensive regulations.

  We are subject to a variety of regulations, including those at the federal,
state and local level. Both the FCC and the FAA regulate towers and other sites
used for wireless communications transmitters and receivers. Such regulations
control siting, lighting and marking of towers and may, depending on the
characteristics of the tower, require prior approval or registration of tower
facilities. Wireless communications devices operating on towers are separately
regulated and independently licensed based upon the regulation of the
particular frequency used. Proposals to construct new communication sites or to
modify existing communication sites are reviewed by both the FCC and the FAA to
ensure that a site will not present a hazard to aviation. Construction or
modification of such structures is also subject to the requirements of the
National Environmental Policy Act, which requires additional review of any
tower that may have a significant effect upon the quality of the human
environment. Owners of towers may have an obligation to paint them or install
lighting to conform to FCC and FAA standards and to maintain such painting or
lighting. Tower owners also bear the responsibility for notifying the FAA of
any tower lighting failures. We generally indemnify our customers against any
failure to comply with applicable standards. Failure to comply with applicable
requirements may lead to civil penalties.

  Local regulations include city or other local ordinances, zoning restrictions
and restrictive covenants imposed by community developers. These regulations
vary greatly, but typically require tower owners to obtain approval from local
officials or community standards organizations prior to tower construction.
Local regulations can delay or prevent new tower construction or site upgrade
projects, thereby limiting our ability to respond to customers' demands. In
addition, these regulations increase the costs associated with new tower
construction. We cannot assure you that existing regulatory policies will not
adversely affect the timing or cost of new tower construction or that
additional regulations will not be adopted which increase these delays or
result in additional costs to us. These factors could have a material adverse
effect on our growth rate, prospects, financial condition or results of
operations and on our ability to implement and/or achieve our business
objectives in the future. Our customers may also become subject to new
regulations or regulatory policies that adversely affect the demand for
communication sites. See "Business--Regulatory and Environmental Matters."

  In addition, our operations are subject to federal, state and local
environmental laws and regulations regarding the use, storage, disposal,
emission, release and remediation of hazardous and nonhazardous substances,
materials or wastes. Under certain of these environmental laws, we could be
held strictly, jointly and severally liable for the remediation of hazardous
substance contamination at our facilities or at third-party waste disposal
sites, and could also be held liable for any personal or property damage
related to such contamination. Although we believe that we are in substantial
compliance with and have no material liability under applicable environmental
laws, the costs of compliance with existing or future environmental laws and
liability related to those laws may have a material adverse effect on our
growth rate, prospects, financial condition or results of operations.

  We and the wireless service providers that use our towers are also subject to
government requirements and other guidelines relating to radio frequency, or
RF, emissions. The potential connection between RF emissions and certain
negative health effects, including some forms of cancer, has been the subject
of substantial study by the scientific community in recent years. To date, the
results of these studies have been inconclusive. Although we have not been
subject to any claims relating to RF emissions, we may be subject to such
claims in the future.

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

                                       13
<PAGE>

insurance policies are subject to caps and deductibles. We also maintain third
party liability insurance 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 tower or group of towers, could have a material adverse effect on our
growth rate, prospects, financial condition or results of operations.

New technologies may undermine the success of our operations.

  The emergence of new technologies could have a negative impact on our
operations. For example, the FCC has granted license applications for three
low-earth orbiting satellite systems that are intended to provide mobile voice
and data services. Although such systems are highly capital-intensive and
technologically untested, mobile satellite systems could compete with land-
based wireless communications systems. These systems could reduce the demand
for our infrastructure services. These events could have a material adverse
effect on our growth rate, prospects, financial condition or results of
operations.

Because of our holding company structure, we depend on our subsidiaries for
cash flow. SBA's access to this cash flow is restricted.

  We are a holding company with no business operations of our own. Our only
significant asset is and will be the outstanding capital stock of our
subsidiaries. We conduct, and will conduct, all of our business operations
through our subsidiaries. Accordingly, our only source of cash to pay our
obligations is distributions from our subsidiaries of their net earnings and
cash flow. We currently expect that the earnings and cash flow of our
subsidiaries will be retained and used by them in their operations, including
to service their debt obligations. Even if our subsidiaries determined to make
a distribution in respect of their capital stock, we cannot assure you that
applicable state law and contractual restrictions, including the dividend
covenants contained in our senior credit facility, would permit such dividends
or distributions. See "Description of Existing Debt."

Steven E. Bernstein will control the outcome of shareholder votes.

  Steven E. Bernstein, our President and Chief Executive Officer, beneficially
owns 100% of the outstanding shares of Class B common stock. Through his
beneficial ownership of Class B common stock, Mr. Bernstein will control
approximately 79.1% of the total voting power of both classes of the common
stock after consummation of the offering (assuming the exercise of the over-
allotment option in full). As a result, Mr. Bernstein will have the ability to
control the outcome of all matters determined by a vote of our common
shareholders, including the election of all of our directors.

We depend on the services of our executive officers.

  Our success depends to a significant extent upon the continued services of
Steven E. Bernstein, our President and Chief Executive Officer, Ronald G.
Bizick, II, our Executive Vice President-Sales and Marketing, Robert M.
Grobstein, our Chief Accounting Officer, Michael N. Simkin, our Chief Operating
Officer, and Jeffrey A. Stoops, our Chief Financial Officer. Each of Messrs.
Bizick, Grobstein, Simkin and Stoops has an employment agreement. We do not
have an employment agreement with Mr. Bernstein. Mr. Bernstein's compensation
and other terms of employment will be determined by the Board of Directors.
Although we maintain key person life insurance on Mr. Bernstein, such insurance
would not adequately compensate for the loss of his services. The loss of the
services of any of Messrs. Bernstein, Bizick, Grobstein, Simkin, Stoops or
other key managers or employees, could have a material adverse effect upon our
growth rate, prospects, financial condition or results of operations.

We need to attract, retain and manage skilled employees.

  Our business involves the delivery of professional services and is labor-
intensive. Our success depends in large part upon our ability to attract,
develop, motivate and retain skilled employees. We compete with other

                                       14
<PAGE>

wireless communications firms and other enterprises for employees with the
skills required to perform our services. We cannot assure you that we will be
able to attract and retain a sufficient number of highly-skilled employees in
the future or that we will continue to be successful in training, retaining and
motivating employees. The loss of a significant number of employees and/or our
inability to hire a sufficient number of qualified employees could have a
material adverse effect on our growth rate, prospects, financial condition or
results of operations.

If we or our existing shareholders sell additional shares of our Class A common
stock after the offering, it could hurt the market price of our Class A common
stock.

  If we sell a substantial number of shares of our Class A common stock after
the offering, those sales could adversely affect the market price of our Class
A common stock and could impair our ability to raise capital through the sale
of equity securities. Upon completion of the offering, we will have 28,972,866
shares of common stock outstanding (including the 7,723,482 shares of Class B
common stock to be outstanding after the offering, the 8,050,000 shares of
Class A common stock to be issued upon the conversion of the Series A preferred
stock and the 780,000 shares of Class A common stock issued at the closing of
the Com-Net acquisition). In addition, we have reserved for issuance 4,151,383
shares of Class A common stock upon exercise of stock options and 402,500
shares of Class A common stock upon exercise of the outstanding warrant. The
11,538,462 shares (13,269,231 shares if the over-allotment option is exercised
in full) sold in the offering will be freely transferable without restriction
under the Securities Act, unless they are held by "affiliates" of ours as that
term is used under the Securities Act. Of the remaining 17,434,404 shares
(15,703,635 shares if the over-allotment option is exercised in full),
15,773,482 shares will be freely transferable without restriction under the
Securities Act, unless they are held by our "affiliates" and will be available
for public sale upon expiration of the "lock-up" agreements described below.
The remaining 1,660,922 shares will be "restricted securities" as that term is
defined in Rule 144 and subject to the volume restrictions of Rule 144.
Substantially all of these restricted securities are entitled to demand and
piggyback registration rights under certain circumstances.

  We intend to file a registration statement under the Securities Act after the
offering to register shares of Class A common stock reserved for issuance under
the 1996 Stock Option Plan and the 1999 Equity Participation Plan. This
registration would permit the resale of such shares by non-affiliates upon
issuance in the public market without restriction under the Securities Act.
Such registration statement will automatically become effective immediately
upon filing. See "Management."

  In connection with the offering and subject to certain exceptions, we, all of
our executive officers and directors and holders of our Series A preferred
stock have agreed not to sell any shares of Class A common stock, or any
securities which may be converted into or exchanged for any such shares of
Class A common stock or substantially similar securities, for a period of 180
days after the date of this prospectus without the prior written consent of
Lehman Brothers Inc., subject to typical exceptions. In addition, our employees
who will own 10,000 or more vested options during the 180-day period described
above will execute similar "lock-up" agreements. See "Underwriting."

The value of shares of Class A common stock purchased in the offering will be
diluted.

  Persons purchasing shares of Class A common stock in the offering will incur
immediate and substantial dilution in net tangible book value per share. In
addition, to the extent that outstanding options and warrants to purchase Class
A common stock are exercised, there could be substantial additional dilution.
See "Dilution."

There is no existing market for our Class A common stock. The share price for
our Class A common stock may fluctuate significantly.

  Prior to the offering, there has been no public market for the Class A common
stock. We cannot assure you that an active trading market will develop upon
completion of the offering or, if it does develop, that it

                                       15
<PAGE>


will be sustained. The initial public offering price of the Class A common
stock was determined by negotiation among us and the representatives of the
underwriters, and may not be representative of the price that will prevail in
the open market after the offering. See "Underwriting" for a discussion of the
factors that were considered in determining the initial public offering price.

  The market price of the Class A common stock after the offering may be
significantly affected by factors such as quarterly variations in our results
of operations, changes in government regulations, the announcement of new
contracts by us or our competitors, technological innovation of ours or of our
competitors, general market conditions specific to our industry, changes in
general economic conditions and volatility in the financial markets. These
fluctuations may adversely affect the market price of the Class A common stock.

Our articles of incorporation and by-laws include provisions that may
discourage a change of control transaction which may affect the rights of
holders of our Class A common stock.

  Upon consummation of the offering, our articles of incorporation will allow
our Board of Directors to issue up to 30,000,000 shares of preferred stock and
to fix the rights, privileges and preferences of these shares without any
further vote or action by the shareholders. The rights of the holders of our
Class A common stock will be subject to, and may be adversely affected by, the
rights of the holders of any preferred stock that may be issued in the future.
While we have no present intention to issue shares of preferred stock, any such
issuance could be used to discourage, delay or make more difficult a change in
control of SBA. In addition, our articles of incorporation provide for a
staggered Board of Directors and our by-laws impose restrictions on calling
special meetings of shareholders and introducing shareholder proposals. Each of
these features could also be used to discourage, delay or make more difficult a
change in control of SBA. See "Description of Capital Stock."

                                USE OF PROCEEDS

  We estimate that the net proceeds to SBA from the offering, after deduction
of the underwriting discount and estimated offering expenses, will be
approximately $117.0 million (assuming an offering price at the mid-point of
the proposed range). Each share of Series A preferred stock will automatically
convert into one share of Series B preferred stock and one share of Class A
common stock upon consummation of the offering. We expect to use approximately
$38.3 million of the net proceeds from the offering to finance the construction
and acquisition of towers, and for general working capital purposes. We may
also use such net proceeds to finance acquisitions of other tower companies or
other related businesses. In addition, we expect to use approximately $32.7
million of these net proceeds to pay all outstanding dividends on all
outstanding shares of our Series A preferred stock and to redeem all
outstanding shares of our Series B preferred stock. We also expect to use
approximately $46.0 million to repay revolving credit borrowings under our
senior credit facility. An affiliate of Lehman Brothers, one of the
underwriters in the offering, is a lender under the senior credit facility. We
have used borrowings under the senior credit facility to finance our business
plan. The weighted average interest rate of revolving credit loans outstanding
under the senior credit facility was 8.437% at March 31, 1999. The revolving
credit loans mature on December 31, 2004. See "Description of Existing Debt--
The Senior Credit Facility" for more information on the calculation of interest
under the senior credit facility. Pending these uses, we will invest the net
proceeds in short-term government obligations.

                                DIVIDEND POLICY

  We have never paid dividends on the common stock, and we do not anticipate
paying dividends in the foreseeable future. Any determination to pay cash
dividends in the future will be at the discretion of our Board of Directors and
will depend upon our results of operations, financial condition, contractual
restrictions and other factors deemed relevant at that time by the Board of
Directors.

  Our ability to pay dividends on the common stock is dependent upon the
ability of our subsidiaries to pay dividends, or otherwise loan, advance or
transfer funds, to us. The terms of our indebtedness impose limitations on our
ability to pay dividends or make other distributions on our capital stock. See
"Description of Existing Debt."

                                    DILUTION

  Dilution is the amount by which the offering price paid by the purchasers of
the Class A common stock offered hereby will exceed the net tangible book value
per share of Class A common stock after the offering. Net tangible book value
per share is determined at any date by subtracting our total liabilities from
the total book value of our tangible assets and dividing the difference by the
number of shares of common stock deemed to be outstanding at that date.

  Our net tangible book value as of March 31, 1999 was $(53.2) million or
$(5.94) per share. After giving effect to the receipt of approximately $117.0
million of estimated net proceeds from the sale of shares of Class A common
stock in the offering and to the conversion of our outstanding Series A
preferred stock that will occur automatically upon consummation of the
offering, our pro forma net tangible book value at March 31, 1999 would have
been approximately $61.8 million or $2.19 per share. This represents an
immediate increase in pro forma net tangible book value of $8.13 per share to
existing shareholders and an immediate dilution of $8.81 per share to new
investors purchasing shares of Class A common stock in the offering. The
following table illustrates the substantial and immediate per share dilution to
new investors (assuming an offering price at the mid-point of the proposed
range):

  The above tables assume no exercise of options outstanding as of March 31,
1999 and no exercise of the warrant to purchase shares of our Class A common
stock issued at the time of the offering of the Series A preferred stock. It
also excludes the conversion of Series A preferred stock into 8,050,000 shares
of Class A common stock. As of March 31, 1999, there were 1,656,783 shares of
Class A common stock reserved for issuance pursuant to outstanding stock
options and 402,500 shares of Class A common stock issuable upon the exercise
of the outstanding warrant at exercise prices ranging from $0.05 to $4.00 per
share. To the extent that any of such shares are issued, there will be further
dilution to new investors. See "Description of Capital Stock."

(a) As of March 31, 1999, we had $40.0 million of borrowings outstanding under
  our senior credit facility, of which $15.0 million were revolving credit
  borrowings. We expect the actual amount of revolving credit borrowings
  outstanding at the closing of the offering to be higher as we continue to
  borrow to finance our business plan.
(b) Each share of Series A preferred stock is convertible into one share of
  Series B preferred stock and one share of Class A common stock. "As adjusted"
  assumes redemption of the Series B preferred stock.
(c) The "as adjusted" number does not include (1) 2,556,783 shares of Class A
  common stock that have been reserved for issuance pursuant to outstanding
  options, (2) 1,600,000 shares of Class A common stock that are reserved for
  issuance upon exercise of options that may be issued in the future under our
  1999 Equity Participation Plan, (3) 402,500 shares of Class A common stock
  that are reserved for issuance upon exercise of the warrant that we granted
  to BT Alex. Brown in connection with the offering of our Series A preferred
  stock. See "Management--1996 Stock Option Plan" and "--1999 Equity
  Participation Plan."
(d) The "as adjusted" number also does not include the 780,000 shares of Class
  A common stock that we issued upon the acquisition of Com-Net. We may have to
  issue additional shares of Class A common stock to the former shareholders of
  Com-Net if certain agreed-upon 1999 and 2000 earnings targets are achieved.
  These additional shares are not included in the "as adjusted" number. See
  "Business--Company Services--Site Development Business--The Com-Net
  Acquisition."

(e) Reflects the surrender as of March 31, 1999 to SBA of 349,085 shares of
  Class B common stock by Mr. Bernstein to repay a loan made to him in 1997.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

  The following unaudited pro forma condensed consolidated financial statements
are based on our historical financial statements during the periods presented.
The unaudited pro forma consolidated statements of operations give effect to
the SBA pro forma transactions, which are (1) all individually immaterial
acquisitions completed during 1998 and the three months ended March 31, 1999
and (2) the issuance of Class A common stock and the application of the net
proceeds as described under "Use of Proceeds," as if each had occurred as of
the beginning of the periods presented. The unaudited pro forma consolidated
balance sheet as of March 31, 1999 gives pro forma effect to the issuance of
the Class A common stock and the application of the net proceeds as described
under "Use of Proceeds," as if each had occurred as of March 31, 1999. The pro
forma adjustments are described in the accompanying notes and are based upon

(a) Reflects the estimated net proceeds from the offering of approximately
    $117.0 million, which is net of the estimated underwriting discounts and
    offering expenses totaling approximately $9.9 million.

(b) Reflects use of proceeds from the offering to pay all accrued dividends on
    outstanding shares of Series A preferred stock and to redeem all
    outstanding shares of Series B preferred stock for a total of $32.5
    million. Also reflects the issuance of 8,050,000 shares of Class A common
    stock as a result of the Series A preferred stock conversion that will
    occur automatically upon the consummation of the offering.

(c) Reflects receipt of a shareholder note in the amount of approximately $3.8
    million. Upon consummation of the offering, Steven E. Bernstein will repay
    a loan made to him in 1997 by surrendering to SBA 349,085 shares (as of
    March 31, 1999) of his Class B common stock valued at the midpoint of the
    range of the initial public offering price.

(d) Reflects use of proceeds from the offering to repay approximately $15.0
    million of revolving credit loans and accrued interest thereon, which
    represents all amounts then outstanding under our senior credit facility.
    We expect the actual amount of revolving credit loans outstanding at the
    closing of the offering to be higher as we continue to borrow to finance
    our business plans.

(a) For the year ended December 31, 1995, selling, general and administrative
    expense includes cash compensation expense of $1.3 million representing the
    amount of officer compensation in excess of what would have been paid had
    the officer employment agreements entered into in 1997 been in effect
    during that period. For the year ended December 31, 1996, selling, general
    and administrative expense includes non-cash compensation expense of $7.0
    million incurred in connection with the consolidation of the predecessor
    companies and cash compensation expense of $4.9 million representing the
    amount of officer compensation in excess of what would have been paid had
    the officer employment agreements entered into in 1997 been in effect
    during that period. For the year ended December 31, 1997, selling, general
    and administrative expense includes non-cash compensation expense of $1.0
    million incurred in the consolidation of the predecessor companies. For the
    year ended December 31, 1998, selling, general and administrative expense
    includes non-cash compensation expense of $0.6 million incurred in
    connection with the issuance of stock options and Class A common stock.
(b) Selling, general and administrative expense includes corporate development
    expenses associated with our site leasing business that were incurred in
    connection with the acquisition or construction of owned towers. These
    expenses consist of compensation and overhead costs that are not directly
    related to the administration or management of existing towers. All of
    these costs are expensed as incurred. The amount of these corporate
    development expenses for the periods presented was as follows:

(c) Provision for income taxes represents a pro forma calculation (40%) for the
    years ended December 31, 1994, 1995 and 1996, when we were treated as an S
    Corporation under Subchapter S of the Internal Revenue Code of 1986, as
    amended. We converted to a C Corporation in 1997. Provision (benefit) for
    income taxes for the years ended December 31, 1997 and 1998 and for the
    three months ended March 31, 1998 and 1999 represents an actual provision
    (benefit). For 1997, the effective rate was in excess of the 40% rate used
    in the pro forma calculations due to the tax effect of our conversion to a
    C Corporation.
(d) EBITDA represents earnings before interest income, interest expense, other
    income, income taxes, depreciation and amortization. EBITDA is commonly
    used in the telecommunications industry to analyze companies on the basis
    of operating performance, leverage and liquidity. Adjusted EBITDA excludes
    the effect of the non-cash compensation expense referred to in footnote (a)
    above. Adjusted EBITDA is not intended to represent cash flows for the
    periods presented, nor has it been presented as an alternative to operating
    income or as an indicator of operating performance and should not be
    considered in isolation or as a substitute for measures of performance
    prepared in accordance with generally accepted accounting principles.
    Companies calculate Adjusted EBITDA differently and, therefore, Adjusted
    EBITDA as presented for us may not be comparable to Adjusted EBITDA
    reported by other companies. See our Consolidated Statements of Cash Flows
    in our Consolidated Financial Statements contained elsewhere in this
    prospectus.
(e) We define "tower cash flow" as site leasing revenue less cost of site
    leasing revenue (exclusive of depreciation). Tower cash flow includes
    deferred revenue attributable to certain leases. We believe tower cash flow
    is useful because it allows you to compare tower performance before the
    effect of expenses (selling, general and administrative) that do not relate
    directly to tower performance. We define "annualized tower cash flow" as
    tower cash flow for the last calendar quarter attributable to our site
    leasing business multiplied by four. Pro forma Annualized tower cash flow
    also includes the effect of fourth quarter acquisitions as if each had
    occurred at the beginning of the period presented.
(f)  Total debt does not include amounts owed to the shareholder of $0.1
     million and $10.7 million as of December 31, 1995 and 1996, respectively.
     These amounts were paid in March 1997.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

  We are a leading independent owner and operator of wireless communications
infrastructure in the United States. Our strategy is to use our historical
leadership position in the site development business, a project revenue
business, to expand our ownership and leasing of communication towers, a
recurring revenue business. We are transitioning our revenue stream from
project driven revenues to recurring revenues through the leasing of antenna
space at or on communications facilities.

  While we intend to continue to offer site development services to wireless
carriers where demand and profitable opportunities exist, we will emphasize our
site leasing business through the construction of owned towers for lease to
wireless service providers, the acquisition of existing sites and the leasing,
subleasing and management of other antenna sites. We believe that as the site
development industry matures, our revenues and gross profit from the consulting
segment of that business will continue to decline substantially in the near
term and this rate of decline will increase for the foreseeable future as
wireless service providers choose to outsource ownership of communication sites
in order to conserve capital. We also believe that, over the longer term, our
site leasing revenue will increase as carriers move to outsource ownership and
management of towers and as the number of towers we own grows.

  As a result of these trends and the shift in focus of our business, our
earnings and EBITDA declined in 1997 and 1998 from prior periods and capital
expenditures increased sharply as we accumulated towers. We expect capital
expenditures to increase even more in 1999. In addition, we anticipate that our
operating expenses may remain at or above 1998 levels as we continue to
construct and acquire tower assets.

  We derive our revenues from two businesses--site development and site
leasing. Our site development business consists of site development consulting
and site development construction. We provide site development services, both
consulting and construction, on a contract basis which is usually customer and
project specific. We generally charge for site development services on either a
fixed price basis or a time and materials basis. Approximately 80%, 61% and 35%
of site development services were performed on a time and materials basis in
1996, 1997 and 1998, respectively, and approximately 31% and 13% of site
development services were performed on a time and materials basis in the three
months ended March 31, 1998 and 1999, respectively. We also provide site
leasing services on a contract basis. Revenue from our site development
business may fluctuate from period to period depending on construction
schedules, which are a function of our clients' build-out schedules, weather
and other factors. Our antenna site leases are typically long-term agreements
with renewal periods. Leases are generally paid on a monthly basis. Because of
the low variable operating costs of the site leasing business, additional
tenants on a tower generate disproportionately larger increases in tower cash
flow.

  We are in the process of acquiring and constructing towers to be owned by us
and leased to wireless service providers. We intend to continue to make
strategic acquisitions in the fragmented and rapidly consolidating tower owner
and operator industry. We completed our first tower acquisition in June 1997
and spent $17.7 million on capital expenditures in 1997 and $138.1 million in
1998 to acquire and construct tower assets and acquire a tower construction
company. Of the 642 towers we owned or controlled as of April 30, 1999, 418
were new builds. At that date, we had non-binding mandates to build over 400
additional towers under build-to-suit programs (the majority of which we expect
will result in binding anchor tenant lease agreements). We believe we have one
of the largest number of non-binding build-to-suit mandates from wireless
service providers in the industry. In addition, we are currently actively
negotiating to acquire additional towers. At April 30, 1999, we had letters of
intent or definitive agreements to acquire 51 additional towers in a number of
separate transactions for an aggregate purchase price of approximately $12.6
million. We cannot assure you that we will be able to close these transactions,
or identify towers or tower companies to acquire in the future.

Tower Economics

  We intend to increase the site leasing portion of our business by
constructing new multi-tenant towers, primarily through build-to-suit programs
for wireless service providers, and by making selective acquisitions of
existing towers and tower companies. We evaluate potential tower construction
and acquisition opportunities for projected future operating results before
making any capital investments.

  The total cost of constructing a tower can vary significantly from site to
site, based upon capacity, geographic location and other factors. The primary
components of tower costs are the tower structure and related components, tower
foundations, labor, site preparation and finish and providing vehicular and
utilities access. If we are responsible for the zoning of a site prior to
construction (which is often the case), the cost associated with obtaining the
necessary zoning may also be material. We estimate that the average cost of
constructing a multi-tenant lattice tower is approximately $225,000 exclusive
of land costs, although this estimate may vary from site to site. While we may
purchase the underlying property, we typically lease any necessary real estate
pursuant to a long-term lease. The typical property lease has a term of five
years, usually provides for annual or periodic price increase and gives us the
option to renew the lease for up to four or five additional five-year terms.

New Tower Builds

  As part of our new build strategy, we generally begin construction of a new
tower only if an anchor tenant (which is typically a PCS, cellular or ESMR
provider) has signed an antenna site lease agreement with us. In some cases we
may build towers before we have obtained a tenant, although we do not expect to
do this very often. The tower site is marketed to other wireless service
providers whose monthly rents vary based usually on location, the different
antenna installations and tower loading requirements of each type of service.
The typical PCS, cellular or ESMR provider pays a monthly rent substantially
greater than that of the typical paging provider. Other tenants, including
local wireless service providers, generally pay lower monthly rent. Anchor
tenants usually receive a discount from the rent paid by subsequent tenants of
the same type of wireless service. In certain cases, an anchor tenant may also
enjoy an introductory lease rate for a period of time. Our objective is to
construct towers for identified anchor tenants in locations where we believe we
can secure other wireless providers as additional tenants. Through the addition
of new tenants, we seek to achieve a target multiple of tower-level cash flow
to the cost of construction by the end of a specified period following
construction. We believe that our targeted multiple, which we constantly
evaluate and is subject to change from time to time, can be achieved through a
variety of tenant mixes ranging from two to three PCS, cellular or ESMR tenants
to a greater number of paging or local wireless service providers. Additional
tenants provide an increase in revenues without generating significant
increases in operating expense. The expenses associated with tower ownership
are limited and generally remain fixed regardless of the number of tenants on
the tower. These expenses are primarily ground lease payments, real estate
taxes, utilities, insurance and maintenance. Because of the operating leverage
of the site leasing business, additional tenant leases generate a
disproportionately higher increase in tower cash flow.

  We build towers for our ownership on locations selected by us or, in the case
of carrier build-to suit programs, by the carrier. Build-to-suit projects
typically originate from a proposal we submit in response to a request from a
wireless service provider. If the wireless service provider accepts the terms
of our proposal, the provider will award us a non-binding mandate to pursue:
(1) specific sites: (2) search rings: or (3) general areas. Based on the status
of the site we have been given a mandate to pursue, we will perform due
diligence investigations for a designated period, during which time we will
analyze the site based on a number of factors, including colocation
opportunities, zoning and permitting issues, economic potential of the site,
difficulty of constructing a multi-tenant tower and remoteness of the site.
These mandates are non-binding agreements and either party may terminate the
mandate at any time. In some cases we must build a tower for the carrier if no
suitable colocation site is available, regardless of the results of our due
diligence and marketability analysis.

  If we conclude that it is economically feasible to construct the tower after
our due diligence investigation during the mandate, we will enter into an
antenna site lease agreement with the provider. The antenna site lease
agreement typically provides that the lessees' obligations are conditioned on
our receipt of all necessary zoning

                                       27
<PAGE>

approvals where zoning remains to be obtained. We have negotiated several
master build-to-suit programs with PCS, cellular and ESMR carriers. Some
antenna site lease agreements contain penalty or forfeiture provisions in the
event the tower is not completed within specified time periods.

Com-Net Acquisition

  We recently acquired Com-Net and an affiliated entity for $1.0 million in
cash, $7.0 million of assumed debt and 780,000 shares of our Class A common
stock (480,000 of which were pledged to us and will be returned to us if
certain earnings targets are not met). In addition, the shareholders of Com-Net
may receive up to $2.5 million in cash and 320,000 additional shares of Class A
common stock if certain 1999 earnings targets are met, and up to an additional
400,000 shares of Class A common stock if certain 2000 earnings targets are
met. Substantially all of Com-Net's revenues have been derived from site
development activities, primarily construction services.

Future Acquisitions

  We also regularly explore tower acquisition opportunities as part of our
growth strategy. While we evaluate potential tower acquisitions on an
individual basis, our acquisition criteria is similar to our construction
criteria. In general, we seek to acquire towers in locations where we believe
we will be able to secure other wireless service providers as tenants so that
the tower will generate a targeted multiple of tower-level cash flow by a
certain time period after its acquisition. In making this determination, we
evaluate several factors, including: the existing number of tenants, current
revenue of the tower, tower location, available tower capacity for additional
tenants and the availability and likelihood of securing additional tenants.

  While we use projections of future tower cash flows when evaluating potential
tower builds or acquisitions, we cannot assure you that our projections will
prove to be accurate nor can we assure you that we will be able to successfully
market a tower to other tenants or implement our build-out strategy on the
timetable currently contemplated or at all. Numerous factors affect the
economics of each tower, many of which are beyond our control. We cannot assure
you that any particular tower will generate the revenues projected at the time
it is first constructed or acquired by us.

Future Compensation Charges Related to Stock Option Grants

  In April 1999, we granted options to employees for the purchase of 900,000
shares of our Class A common stock at an exercise price of $8.00 per share
pursuant to our 1999 Equity Participation Plan. These options will vest over
the next three years, commencing on December 31, 1999 and ending in April 2002.
Since the exercise price of these options is substantially below the
anticipated price to the public in the offering, we will record non-cash
compensation charges in each quarter during the vesting period beginning with
the second quarter of this year. The amount of these charges is a function of
the price to the public in the offering. Based upon the midpoint of the
anticipated price range in the offering, these charges will total approximately
$1.7 million over the next three years.

Results of Operations

  As we continue our transition into site leasing, operating results in prior
periods may not be meaningful predictors of future prospects. You should be
aware of the dramatic changes in the nature and scope of our business when
reviewing the ensuing discussion of comparative historical results. We expect
that the acquisitions consummated to date and any future acquisitions, as well
as our new tower builds, will have a material impact on future revenues,
expenses and net income. In particular, depreciation and amortization and
interest expense increased significantly in 1998 and in the three months ended
March 31, 1999 over the prior periods, and will continue to increase
significantly in future periods. We believe that our construction programs will
have a material adverse effect on future results of operations, until such
time, if ever, as the newly constructed towers attain higher levels of tenant
use.

 First Quarter 1999 Compared to First Quarter 1998

  Total revenues decreased 6.6% to $13.7 million for the first quarter of 1999
from $14.7 million for the first quarter of 1998. We derive our revenues from
two businesses--site development and site leasing. Our site

                                       28
<PAGE>

development business consists of site development consulting and site
development construction. Site development revenue decreased 31.6% to $8.6
million in the first quarter of 1999 from $12.5 million in the first quarter of
1998 due to a substantial decline in site development consulting revenue, which
was partially offset by a substantial increase in site development construction
revenue. Site development consulting revenue decreased 59.7% to $3.9 million in
the first quarter of 1999 from $9.7 million in the first quarter of 1998, due
primarily to the decreased demand for site acquisition and zoning services from
PCS licensees, as well as the increasing acceptance by wireless carriers of
outsourced communication site infrastructure through build-to-suit programs.
Site development construction revenue increased 66.2% to $4.7 million for the
first quarter of 1999 from $2.8 million for the first quarter of 1998, due to
the expanded customer base of our construction company and the number of
projects on which services were rendered. We expect our site development
construction revenue to continue to increase substantially as a result of the
recently completed Com-Net acquisition. Site leasing revenue increased 138.2%
to $5.1 million for the first quarter of 1999 from $2.2 million for the first
quarter of 1998, due to the substantially greater number of towers in our
portfolio during the 1999 period compared to 1998.

  Total cost of revenues decreased 14.2% to $9.0 million for the first quarter
of 1999 from $10.5 million for the first quarter of 1998. Site development cost
of revenue decreased 26.3% to $6.6 million for the 1999 period from $9.0
million for the 1998 period due to the decrease in the site development
consulting cost of revenue, which was partially offset by an increase in the
site development construction cost of revenue. Site development consulting cost
of revenue decreased 58.1% to $3.0 million for the first quarter of 1999 from
$7.2 million for the first quarter of 1998 due primarily to the lower level of
activity. Site development construction cost of revenue increased to $3.6
million for the 1999 period from $1.7 million for the 1998 period, due
primarily to the increased level of activity. Site leasing cost of revenue
increased 57.8% to $2.4 million for the 1999 period from $1.5 million for the
1998 period, due primarily to the increased number of owned or controlled
towers resulting in an increased amount of lease payments to land owners.

  Gross profit increased 12.5% to $4.7 million for the first quarter of 1999
from $4.2 million for the first quarter of 1998 due to the increase in high
margin site leasing revenue which was offset by a decrease in gross profit in
our site development business. Gross profit from site development decreased
44.9% to $2.0 million in the 1999 period from $3.5 million in the 1998 period,
due to the decline in site development consulting activity and a slight decline
in that segment's gross profit in the 1999 period to 22.7% from 25.5% in the
1998 period. Gross profit from site development construction remained flat at
$1.1 million in each of the periods. Gross profit margin on site development
construction dropped in the 1999 period to 22.8% from 37.7% in the 1998 period,
reflecting the increased use of subcontractor labor in 1999. In the future, we
believe our gross profit margin on site development construction may be lower
than that experienced in the first quarter of 1999 as we integrate Com-Net's
business, which has historically had gross profit margins in the 15% to 20%
range. Gross profit for the site leasing business increased 324.2% to $2.8
million in the first quarter of 1999 from $0.7 million in the first quarter of
1998, and site leasing gross profit margin improved to 53.8% in the 1999 period
from 30.2% in the 1998 period. The increased gross profit and improved margin
were both due to the substantially greater number of towers owned or controlled
in the 1999 period. As a percentage of total revenues, total gross profit
increased to 34.4% in the 1999 period from 28.5% in the 1998 period due to
increased levels of higher margin site leasing gross profit.

  Selling, general and administrative expenses increased 3.4% to $4.1 million
for the first quarter of 1999 from $3.9 million for the first quarter of 1998.
As a percentage of total revenues, selling, general and administrative expenses
increased to 29.7% for the 1999 period from 26.8% in the 1998 period.

  Depreciation and amortization increased to $3.1 million for the first quarter
of 1999 as compared to $0.5 million for the first quarter of 1998. This
increase is directly related to the increased amount of fixed assets (primarily
towers) we owned or controlled in the 1999 period as compared to the 1998
period.

  Operating loss increased to $(2.5) million for the first quarter of 1999 from
$(0.3) million for the first quarter of 1998 as a result of the increased
depreciation and amortization expenses in 1999 associated with the increase in
tower ownership. Other income (expense) increased to $(5.5) million for the
first quarter of 1999 from $(1.1) million for the first quarter of 1998. This
increase resulted primarily from the interest expense associated with our
senior discount notes. The extraordinary item in the first quarter of 1999 of
$1.1 million relates to the write-off of deferred financing fees associated
with our prior bank credit agreement. Net loss was $(8.4) million for the 1999
period as compared to net loss of $(1.5) million for the 1998 period.

 1998 Compared to 1997

  Total revenues increased 7.5% to $59.1 million for 1998 from $55.0 million
for 1997. Total site development revenue decreased 3.2% to $46.7 million in
1998 from $48.2 million in 1997 due to a substantial decline in site
development consulting revenue, which was largely offset by a substantial
increase in site development construction revenue. Site development consulting
revenue decreased 41.6% to $27.4 million for 1998 from $47.0 million for 1997,
due primarily to the decreased demand for site acquisition and zoning services
from PCS licensees, as well as the increasing acceptance by wireless carriers
of outsourced communication site infrastructure through build-to-suit
programs. Site development construction revenue increased to $19.3 million for
1998 from $1.2 million for 1997, due to the acquisition of CSSI, our
construction subsidiary, in September 1997 and higher levels of activity. Site
leasing revenue increased 83.4% to $12.4 million for 1998 from $6.8 million
for 1997, due to a substantial number of revenue producing towers added during
the period through new builds and acquisitions.

  Total cost of revenues increased 18.9% to $43.8 million for 1998 from $36.8
million for 1997. Site development cost of revenue increased 16.0% to $36.5
million in 1998 from $31.5 million in 1997 due to a substantial increase in
site development construction cost of revenue, which was partially offset by a
decrease in site development consulting cost of revenue. Site development
consulting cost of revenue decreased 28.5% to $21.9 million for 1998 from
$30.6 million for 1997, due to lower revenue. Site development construction
cost of revenue increased to $14.6 million for 1998 from $0.8 million for
1997, due again to the inclusion of the construction subsidiary for a full
twelve months in 1998 versus three months in 1997. Site leasing cost of
revenue increased 35.9% to $7.3 million for 1998 from $5.4 million for 1997,
due primarily to the increased volume of towers owned resulting in an
increased amount of lease payments to land owners.

  Gross profit decreased 15.7% to $15.3 million for 1998 from $18.2 million
for 1997, due to the decrease in site development consulting revenue and lower
margins earned on such revenue, which more than offset gross profits from
increased site development construction and site leasing. Gross profit for
site development consulting services decreased 66.1% to $5.6 million for 1998
from $16.4 million for 1997. The lower gross profit margins experienced in
1998 were due to more work being performed on a fixed fee basis and the
completion of a number of large projects on which we experienced
proportionately higher expenses than in the earlier stages of a project. Gross
profit for site development construction services increased to $4.7 million
for 1998 from $0.4 million for 1997 due to higher revenue. Gross profit for
the site leasing business increased 264.6% to $5.1 million for 1998 from $1.4
million for 1997 due primarily to higher revenue but also due to higher gross
profit margins earned on towers owned as opposed to the margins earned on our
lease/sublease business which contributed most of our 1997 site leasing
revenue. As a percentage of total revenues, gross profit decreased to 25.9%
for 1998 as compared to 33.0% for 1997 due to significantly lower site
development consulting gross profit.

  Selling, general and administrative expenses increased 52.1% to $18.3
million for 1998 from $12.0 million for 1997 primarily due to the addition of
personnel, the expansion of office space and overall increases in operating
expenses attributable to the growth in the organization and building of our
tower development infrastructure. We also incurred $1.0 million of direct
expenses on acquisitions or proposed new tower builds which were not
completed. As a percentage of total revenues, selling, general and
administrative expenses increased to 31.0% for 1998 from 21.9% in 1997.

  Depreciation and amortization increased to $5.8 million for 1998 as compared
to $0.5 million for 1997. This increase is directly related to the increased
amount of fixed assets (primarily towers) we owned in 1998 as compared to
1997.

  Operating income (loss) decreased to $(8.8) million for 1998 from $5.6
million for 1997 as a result of the factors discussed above. Other income
(expense) decreased to $(12.6) million for 1998 from $0.2 million for 1997.
This decrease resulted primarily from the interest expense associated with the
senior discount notes offset by interest income that was earned on cash
balances. Net income (loss) was $(19.9) million for 1998 as compared to net
income of $0.3 million for 1997.

 1997 Compared to 1996

  Total revenues decreased 15.1% to $55.0 million for 1997 from $64.8 million
for 1996. Total site development revenue decreased 20.0% to $48.2 million in
1997 from $60.3 million in 1996 due to a substantial

                                      30
<PAGE>

decline in site development consulting revenue. Site development consulting
revenue decreased 22.0% to $47.0 million for 1997 from $60.3 million for 1996,
due primarily to the decreased demand for site development services from A- and
B- block broadband PCS licensees, partially offset by the increased demand for
services from D-, E-, and F- block broadband PCS licensees and ESMR providers.
This decreased demand from A- and B- block licensees resulted from their
initial markets nearing build-out completion and not yet having commenced
anticipated build out of secondary or tertiary markets, as well as the
increasing acceptance by these providers of outsourced communication site
infrastructure through build-to-suit programs. Site development construction
revenue were $1.2 million for 1997. There was no site development construction
revenue in 1996 because we did not acquire CSSI, our construction subsidiary,
until September 1997. Site leasing revenue increased 49.2% to $6.8 million for
1997 from $4.5 million for 1996, due primarily to the continued growth of
lease/sublease business from new and existing paging clients, and also to our
ownership of 51 revenue producing towers at year end 1997.

  Total cost of revenues decreased 15.3% to $36.8 million for 1997 from $43.5
million for 1996. Site development cost of revenue decreased 21.0% to $31.5
million in 1997 from $39.8 million in 1996 due to a decrease in site
development consulting cost of revenue. Site development consulting cost of
revenue decreased 23.0% to $30.6 million for 1997 from $39.8 million for 1996
due primarily to decreased site development consulting revenue. Site
development construction cost of revenue was $0.8 million for 1997. Because we
did not purchase CSSI until September 1997, there was no site development
construction cost of revenue in 1996. Site leasing cost of revenue increased
47.2% to $5.4 million in 1997 from $3.6 million in 1996, due primarily to the
higher revenue.

  Gross profit decreased 14.9% to $18.2 million for 1997 from $21.3 million for
1996, due primarily to the decrease in site development revenue. Gross profit
for site development consulting services decreased 19.9% to $16.4 million for
1997 from $20.5 million for 1996. This decrease was related to the decrease in
revenue. Gross margin percentages were constant at 34%. Gross profit for site
development construction was $0.4 million for 1997. Gross profit for the site
leasing business increased 57.3% to $1.4 million for 1997 from $0.9 million for
1996. These increases were attributable to the growth of the lease/sublease
business. As a percentage of total revenues, gross profit remained constant at
33% for 1997 and 1996.

  Selling, general and administrative expenses decreased 32.2% to $12.0 million
for 1997 from $17.8 million for 1996, primarily due to a reduction in executive
compensation and increased 1996 expenses associated with a bonus paid to Mr.
Bernstein, our Chief Executive Officer, and non-cash compensation expense of
$7.0 million relating to the granting of options to our other officers. The
bonus was $4.0 million in 1996. Non-cash compensation expense recorded in 1997
was $1.0 million. As a percentage of total revenues, selling, general and
administrative expenses decreased to 21.9% for 1997 from 27.4% for 1996.
Excluding the effect of the above mentioned bonus and non-cash compensation
expense, selling, general and administrative expenses as a percentage of
revenue would have increased to 20.1% for 1997 from 10% for 1996. This increase
is attributable to the addition of personnel and increased operating expenses
we incurred to grow the site leasing business.

  Depreciation and amortization increased to $0.5 million for 1997 as compared
to $0.2 million for 1996. This increase is directly related to the increased
amount of fixed assets (primarily towers) we owned in 1997 as compared to 1996.

  Operating income increased 63.9% to $5.6 million for 1997 from $3.4 million
for 1996. Other income (expense) was not material in either period. Actual net
income decreased 91.9% to $0.3 million for 1997 from $3.3 million for 1996. On
a pro forma basis, assuming SBA had been a C corporation for both periods, net
income decreased 86.5% to $0.3 million for 1997 from $2.0 million for 1996.
These decreases resulted from a reduction in site development revenues and the
inclusion of a provision for income taxes in 1997. Prior to 1997, we were not
subject to tax at the corporate level.

Liquidity and Capital Resources

  SBA Communications Corporation is a holding company with no business
operations of its own. Its only significant asset is the outstanding capital
stock of its subsidiaries. It conducts all its business operations through its
subsidiaries. Accordingly, its only source of cash to pay its obligations is
distributions from its subsidiaries from their net earnings and cash flow. Even
if our subsidiaries determined to pay a dividend on or make a distribution in
respect of their capital stock, we cannot assure you that our subsidiaries will
generate sufficient cash flow to pay such a dividend or distribute such funds
or that they will be permitted to pay dividends by the terms of our senior
credit facility.

  Net cash used in operations during the three months ended March 31, 1999 was
$4.5 million compared to net cash used in operations of $6.1 million in the
three months ended March 31, 1998. Net cash used in investing activities for
the three months ended March 31, 1999 was $36.9 million compared to $11.1
million for the three months ended March 31, 1998. This increase is
attributable to a higher level of tower acquisition and new build activity in
1999 versus 1998. Net cash provided by financing activities for the three
months ended March 31, 1999 was $16.9 million compared to $134.6 million for
the three months ended March 31, 1998. The 1998 amount includes the proceeds of
the notes.

  Net cash provided by operations during 1998 and 1997 was relatively constant
at $7.5 million and $7.8 million, respectively. Net cash used in investing
activities for 1998 was $138.1 million compared to $17.7 million for 1997. The
increase in cash used in investing activities results from the acquisition and
construction of 443 towers during 1998. Net cash provided by financing
activities for 1998 was $151.3 million compared to $15.6 million for 1997. This
increase is attributable to the proceeds of our senior discount notes.

  Net cash provided by operations during 1997 was $7.8 million compared to $1.2
million in 1996. The increase in net cash provided by operations was primarily
attributable to the decrease in net income together with changes in the account
balances associated with accounts receivable, accounts payable, intangibles and
various tax accounts for the respective periods. Net cash used in investing
activities for 1997 was $17.7 million compared to $0.1 million for 1996. The
increase in cash used for investing activities resulted from the acquisition of
towers and CSSI, a tower construction company. Net cash provided by financing
activities for 1997 was $15.6 million compared to net cash used in financing
activities of $1 million for 1996. The increase in net cash provided by
financing activities was primarily attributable to the proceeds from the sale
of our Series A preferred stock.

  Our balance sheet reflected positive working capital of $6.0 million and $8.1
million as of March 31, 1999 and December 31, 1998, respectively.

  As a result of a preferred stock offering in March 1997, we received net
proceeds of $25.3 million after deducting the agents' commission, offering
expenses and a stock redemption. These proceeds were used primarily for the
repayment of short-term debt, for the funding of various expansion costs, for
the construction and acquisition of various towers and for general working
capital.

  On March 2, 1998 we issued $269.0 million in aggregate principal amount at
maturity of 12% senior discount notes due 2008. This offering provided
approximately $150.2 million of gross proceeds to us. From these gross
proceeds, we repaid approximately $20.2 million of existing indebtedness and
paid approximately $5.7 million of fees and expenses. The remaining proceeds
were used primarily for the acquisition and construction of communications
towers. Prior to March 1, 2003, interest expense on the senior discount notes
will consist solely of non-cash accretion of original issue discount and the
senior discount notes will not require cash interest payments. After such time,
the senior discount notes will have accreted to $269.0 million and will require
annual cash interest payments of approximately $32.3 million. In addition, the
senior discount notes mature on March 1, 2008.

  In February 1999, we entered into a senior credit facility through our
Telecommunications subsidiary with a group of lenders. This $175.0 million
senior credit facility, which replaced our prior $55.0 million credit

                                       32
<PAGE>

facility, consists of a $25.0 million term loan and a $150.0 million revolving
line of credit. The term loan was fully funded at closing. Availability under
the senior credit facility is determined by a number of factors including
number of towers built by us with anchor tenants on the date of completion, the
financial performance of our other towers, site development and construction
segments, as well as by other financial covenants, financial ratios and other
conditions. The senior credit facility, matures December 31, 2004 and, pursuant
to a schedule, amortization and reduced availability begins March 31, 2001.
Borrowings under the senior credit facility bear interest at the eurodollar
rate plus a margin ranging from 2.25% to 3.50% (determined by a leverage ratio)
or a "base rate" (as defined in the senior credit facility) plus a margin
ranging from 1.25% to 2.50% (determined by a leverage ratio). The senior credit
facility is secured by substantially all of the assets of our
Telecommunications subsidiary and its direct and indirect subsidiaries,
requires our Telecommunications subsidiary to maintain certain financial
covenants and places restrictions on, among other things, the payment of
dividends to SBA, the incurrence of debt and liens, disposition of assets,
transactions with affiliates and certain investments. In connection with the
termination of the previous credit agreement, we recorded an extraordinary
charge of approximately $1.1 million representing the write-off of previously
capitalized deferred financing fees related to the previous bank credit
agreement. Deferred financing fees related to obtaining the new senior credit
facility were approximately $3.9 million. Additionally, on March 8, 1999, after
receiving the requisite consents from the holders of our senior discount notes,
we amended the indenture governing the notes to increase one of the categories
of permitted indebtedness from $125.0 million to $175.0 million. In connection
therewith, we paid $2.1 million to the holders of the notes. The amount is also
reflected in deferred financing fees.

  In the event that the business acquired in the Com-Net acquisition achieves
certain EBITDA targets in 1999 and 2000, we may be obligated to issue up to
720,000 additional shares of Class A common stock and to pay up to $2.5 million
to the former shareholders of Com-Net. If the business acquired does not
achieve certain EBITDA targets in 1999, the former shareholders of Com-Net will
return to us up to 480,000 of the shares we issued to them at the closing of
the Com-Net acquisition.

  We currently estimate that we will make at least $160.0 million of capital
expenditures during 1999 for the construction and acquisition of communication
sites, primarily towers, and the acquisition of Com-Net. We currently expect
that capital expenditures will be at the same or higher levels in 2000. We
expect to use cash from operations together with the proceeds of the offering
and availability under our senior credit facility to fund these capital
expenditures. These expected capital expenditures will substantially exhaust
our availability under our senior credit facility. However, the exact amount of
our future capital expenditures will depend on a number of factors. In 1999, we
currently anticipate building a significant number of towers for which we have
non-binding mandates pursuant to our build-to-suit program. We also intend to
continue to explore opportunities to acquire additional towers, tower companies
and/or related businesses. Our capital expenditures in 1999 will depend in part
upon acquisition opportunities that become available during the period, the
needs of our primary build-to-suit customers and the availability to us of
additional debt or equity capital on acceptable terms. In the event that
borrowings under the senior credit facility have otherwise been used when an
acquisition or construction opportunity arises, we would be required to seek
additional debt or equity financing. We cannot assure you that any such
financing will be available on commercially reasonable terms or at all or that
any additional debt financing would be permitted by the terms of our existing
indebtedness.

  Our ability to make scheduled payments of principal of, or to pay interest
on, our debt obligations, and our ability to refinance any such debt
obligations, or to fund planned capital expenditures, will depend on our future
performance, which, to a certain extent, is subject to general economic,
financial, competitive, legislative, regulatory and other factors that are
beyond our control. Our business strategy contemplates substantial capital
expenditures in connection with our planned tower build-out and acquisitions.
Based on our current operations and anticipated revenue growth, we believe
that, if our business strategy is successful, cash flow from operations and the
proceeds of the offering and available borrowings under the senior credit
facility will be sufficient to fund our anticipated capital expenditures in
1999. Thereafter, however, or in the event we exceed our currently anticipated
capital expenditures for 1999, we anticipate that we will need to seek
additional equity

                                       33
<PAGE>

or debt financing to fund our business plan. Failure to obtain any such
financing could require us to significantly reduce our planned capital
expenditures and scale back the scope of our tower build-out or acquisitions,
either of which could have a material adverse effect on our projected financial
condition or results of operations. In addition, we may need to refinance all
or a portion of our indebtedness (including the senior discount notes and/or
the senior credit facility) on or prior to its scheduled maturity. We cannot
assure you that we will generate sufficient cash flow from operations in the
future, that anticipated revenue growth will be realized or that future
borrowings or equity contributions will be available in amounts sufficient to
service our indebtedness and make anticipated capital expenditures. In
addition, we cannot assure you that we will be able to effect any required
refinancing of our indebtedness (including the senior discount notes) on
commercially reasonable terms or at all. See "Risk Factors."

Market Risk

  We are exposed to certain market risks which are inherent in our financial
instruments. These instruments arise from transactions entered into in the
normal course of business, and in some cases, relate to our acquisition of
related businesses. We are subject to interest rate risk on our senior credit
facility and any future financing requirements. Our fixed rate debt consists
primarily of the accreted balance of the notes. Our variable rate debt consists
of borrowings made under the senior credit facility.

  The following table presents the future principal payment obligations and
weighted average interest rates associated with our existing long-term debt
instruments assuming our actual level of long-term indebtedness:

  Our primary market risk exposure relates to (1) the interest rate risk on
long-term and short-term borrowings, (2) our ability to refinance our senior
discount notes at maturity at market rates, (3) the impact of interest rate
movements on our ability to meet interest expense requirements and exceed
financial covenants and (4) the impact of interest rate movements on our
ability to obtain adequate financing to fund future acquisitions. We manage the
interest rate risk on our outstanding long-term and short-term debt through our
use of fixed and variable rate debt and interest rate swaps. While we cannot
predict or manage 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.

Year 2000

  During 1998 we continued our review of the installation of new systems
hardware and software and determined that the installation is on schedule for
completion before the year 2000.

  There are five phases that describe our process in becoming Year 2000
compliant. The awareness phase encompasses developing a budget and project
plan. The assessment phase identifies mission-critical systems to check for
compliance. Both of these phases have been completed. We are at various stages
in the three remaining phases: renovation, validation and implementation.
Renovation is the design of the systems to be Year 2000 compliant. Validation
is testing the systems followed by implementation.

  We have begun implementation of a new financial system. The system is
certified by the vendor as Year 2000 compliant. In conjunction with this
implementation, we have undertaken the renovation of our operational systems.
The testing and implementation of these systems is scheduled for completion in
1999. The cost of the new financial system and renovation of our operational
systems is expected to be approximately $750,000.

                                       34
<PAGE>

  Management is reviewing the state of Year 2000 readiness of third parties
with whom we share a material relationship, such as banks and vendors used by
us. At this time, we are unaware of any third party Year 2000 issues that would
materially effect these relationships or our financial condition.

  We expect to be Year 2000 compliant in 1999 for all major systems. We are
assessing our risks and the full impact on operations if the worst case Year
2000 scenario were to occur. In conjunction with this, we are developing a
contingency plan and expect to complete the development of this plan in 1999.

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.

Recent Accounting Pronouncements

 Comprehensive Income

  In June 1997, the Financial Accounting Standards Board, or FASB, issued SFAS
No. 130, "Reporting Comprehensive Income" which establishes standards for
reporting and display of comprehensive income and its components in a full set
of general-purpose financial statements. This statement requires that an
enterprise classify items of other comprehensive income separately from
accumulated deficit and additional paid-in capital in the equity section of the
balance sheet. Comprehensive income is defined as the change in equity during
the
financial reporting period of a business enterprise resulting from non-owner
sources. During the year ended December 31, 1998, 1997 and 1996 and for the
three months ended March 31, 1999 and 1998, we did not have any changes in our
equity resulting from such non-owner sources and accordingly, comprehensive
income as set forth by SFAS No. 130 was equal to the net loss amounts presented
for the respective periods in our Consolidated Financial Statements.

 Segment Reporting

  In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" which is required to be adopted in fiscal
1998. SFAS No. 131 requires us to report financial and other descriptive
information about our reportable operating segments. Required disclosures
include, among other things, a measure of segment profit or loss, certain
specific revenue and expense items, and segment assets. We have implemented
SFAS No. 131 during 1998.

 Derivative Instruments and Hedging Activities

  In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. SFAS
No. 133 will require that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. SFAS
No. 133 is effective for fiscal years beginning after June 15, 1999. Management
believes that adopting this statement will not have a material impact upon our
results of operations or financial position.

                               INDUSTRY OVERVIEW

General

  We are a leading independent owner and operator of wireless communications
infrastructure in the United States. In order to capitalize on the trend toward
colocation and independent tower ownership in this industry, we have
aggressively expanded our site leasing business by using our nationally
recognized site development experience and strong relationships with wireless
service providers to source opportunities to build and acquire communication
sites. The wireless communications industry continues to grow rapidly as
consumers become more aware of the benefits of wireless services, current
wireless technologies are used in more applications, the cost of wireless
services to consumers declines and new wireless technologies are developed.
Changes in U.S. federal regulatory policy, including the implementation of the
Telecommunications Act of 1996, have led to a significant number of new
competitors in the industry through the auction of frequency spectrum for a
wide range of uses, most notably PCS. This competition, combined with a growing
reliance on wireless services by consumers, has led to an increased demand for
higher quality, uninterrupted service and improved coverage. This demand for
higher quality service and coverage has led to increased demand for
communication sites as new providers build out their networks and existing
providers upgrade and expand their networks to maintain their competitiveness.
We believe that, as the wireless communications industry has become more
competitive, wireless service providers have outsourced certain network
services and build-out activities and colocated transmission equipment with
other providers on multi-tenant towers, in order to maximize their operating
and capital efficiencies. The need for colocation has also been driven by the
growing trend by municipalities to slow the proliferation of towers by
requiring that towers accommodate multiple tenants.

  All of these factors have provided an opportunity for us to develop and own
communication sites, lease antenna space on such sites and provide related
network infrastructure and support services.

Development of the Tower Industry

  The U.S. wireless communications industry was transformed in the 1970s
through the issuance of licenses by the FCC to provide high quality
communications services to vehicle-mounted and hand-held portable telephones,
pagers and other devices. The licensees built and began operating wireless
networks that were supported by communication sites, transmission equipment and
other infrastructure. In the early 1980s, the number of towers began to expand
significantly with the development of more advanced wireless communications
systems, particularly cellular and paging. Nevertheless, as additional towers
were built by the wireless carriers, they often were built for a single purpose
rather than as multiple tenant towers. In addition, these towers were generally
owned and maintained by carriers and were treated as corporate cost centers
operated primarily for the purpose of transmitting or receiving such carriers'
signals.

  During the mid-to-late 1980s, a number of independent operators of towers
began to emerge. These independent tower operators focused on owning and
managing towers with multiple tenants by adding lessees to existing and
reconstructed towers. We believe the majority of these operators were small
business owners with a small number of local towers and few services other than
site leasing. In the last five years, however, several larger independent tower
operators have emerged as demand for wireless services has continued to grow
and as additional high frequency licenses have been awarded for new wireless
services (including PCS, narrowband paging and wireless local loop), each
requiring networks with extensive tower infrastructure. These independent tower
operators have sought to acquire smaller operators as well as clusters of
towers formerly owned by carriers and broadcasters.

  Today, a variety of companies, including wireless carriers, local and long
distance telecommunications companies, broadcasting companies, independent
tower operators, utilities and railroad companies, own towers. Despite the
increasing demand for towers, the tower industry in the United States remains
highly fragmented, with only a few independent tower operators owning a large
number of towers. The pace of consolidation has begun to accelerate, however,
as the larger independent operators continue to acquire small local operators
and purchase towers from wireless communications companies. In addition,
wireless carriers are building out new,

                                       36
<PAGE>

or filling in existing, tower footprints for new and existing wireless
services. Independent operators have also expanded into a number of associated
network and communication site services, including the design of communication
sites and networks, the selection and acquisition of tower and rooftop sites
(including the resolution of zoning and permitting issues) and the construction
of towers. Previously, carriers typically handled such services through in-
house departments, and local nonintegrated service contractors focused on
specific segments such as site acquisition.

Networks and Towers

  Wireless service providers require wireless transmission networks in order to
provide service to their customers. Each of these networks is configured
specifically to meet the coverage requirements of the particular provider and
includes transmission equipment such as antennas placed at various locations
throughout the service area. These locations, or communication sites, are
critical to the operation of a wireless network. A communication site may have
the capacity for multiple antenna installations, or antenna sites, depending on
the size and type of the communication site. The value of a tower generally
depends on its location and the number of antennas that it can support.

  Set forth below is a diagram illustrating the basic functions of each of the
primary components of a "wireless network."



  Communication sites consist of towers, rooftops and other structures upon
which antennas are placed. A typical tower usually includes a compound
enclosing the tower and an equipment shelter (which houses a variety of
transmitting, receiving and switching equipment). The tower can be either a
self-supported or guyed model. There are two types of self-supported models,
the lattice and the monopole. A lattice model is usually tapered from the
bottom up and can have three or four sides of open-framed steel supports. A
monopole is a free-standing tubular structure. Guyed towers gain their support
capacity from a series of guy cables attaching separate levels of the tower to
anchor foundations in the ground. Monopoles typically range in height from 50-
200 feet, lattice towers can reach up to 1000 feet and guyed towers can reach
2000 feet or more.

                                       37
<PAGE>

  Rooftop sites are more common in urban areas where tall buildings are
generally available and multiple communication sites are required because of
high wireless traffic density. One advantage of a rooftop site is that zoning
regulations typically permit installation of antennas. In cases of such high
population density, neither height nor extended radius of coverage are as
important and the installation of a tower structure may prove to be impossible
because of zoning restrictions, land cost and land availability. Antennas may
also be installed on structures such as electric transmission towers, silos,
water tanks, windmills and smokestacks.

 Operation of Two-Way Wireless Systems

  Wireless transmission networks use a variety of radio frequencies to transmit
voice and data. Wireless transmission networks include two-way radio
applications, such as cellular, wide band and narrow band PCS and ESMR
networks, and one way radio applications, such as paging services. Each
application operates within a distinct radio frequency. Although cellular
represents the largest segment of the wireless communications industry, other
wireless technologies are expected to grow significantly.

  Two-way wireless service areas are divided into multiple regions called
"cells," each of which contains a base station consisting of a low-power
transmitter, a receiver and signaling equipment, typically located on a tower.
The cells are usually configured in a grid pattern, although terrain factors
(including natural and man-made obstructions) and signal coverage patterns may
result in irregularly shaped cells and overlaps or gaps in coverage. Cellular
system cells generally have a radius ranging from two miles to 25 miles and PCS
system cells generally have a radius ranging from one-quarter mile to 12 miles,
depending on the PCS technology being used, installation, height and the
terrain. Growing demand for cell sites is one of the primary reasons for
growing demand for our services. The base station in each cell is connected by
microwave, fiber optic cable or telephone wires to a switch, which uses
computers and specially developed software to control the operation of the
wireless telephone system for its entire service area. The switch controls the
transfer of calls from cells within the system and connects calls to the local
landline telephone system or to a long distance telephone carrier.

  Each wireless transmission network is planned to meet a certain level of
subscriber density and traffic demand in addition to providing a certain
geographic coverage. Each transmission requires a certain amount of radio
frequency, so a system's capacity is limited by the amount of frequency that is
available. Each separate transmitter can reuse the same frequency, subject to
certain interference limitations. The design of each wireless system involves
the placement of transmission equipment in locations that will make optimal use
of available frequency based upon projected usage patterns, subject to the
availability of such locations and the ability to use them for wireless
transmission under applicable zoning requirements.

 Wireless Communications

  The wireless communications industry now provides a broad range of services,
including cellular, PCS, paging, SMR and ESMR. The industry has benefited in
recent years from increasing demand for its services, and industry experts
expect this demand to continue to increase. The following table sets forth Paul
Kagan Associates, Inc.'s industry estimates regarding projected subscriber
growth for certain types of wireless communications services.

<PAGE>

  Although Paul Kagan Associates, Inc. is a leading industry analyst, we cannot
assure you that their projections of industry growth will be realized.
Projections are inherently uncertain and actual results will likely differ from
these projections, possibly materially.

  We believe that more communication sites will be required in the future to
accommodate the expected increase in demand for wireless communications
services. In addition, we see additional opportunities with the development of
higher frequency technologies (such as PCS), which have a reduced cell range as
a result of signal propagation characteristics that require a more dense
network of towers. Also, network services may be required to service the
network build-outs of new carriers and the network upgrades and expansion of
existing carriers.

  Current emerging wireless communications systems, such as PCS and ESMR,
represent an immediate and sizable market for providers of communication site
services as they build out large nationwide and regional networks. While
several PCS and ESMR providers have already built limited networks in certain
markets, these providers still need to fill in "dead zones" and expand
geographic coverage. The Cellular Telecommunications Industry Association, or
CTIA, estimates that, as of June 30, 1998, there were 57,674 antenna sites in
the United States. In October 1995, the PCIA, estimated that the number of
antenna sites in the United States for both cellular and PCS providers would
increase by an additional 100,000 antenna sites (more than one of which can be
located on a single communication site) over the subsequent ten years as
cellular systems expand coverage and PCS systems are deployed.

  As a result of advances in digital technology, ESMR operators have also begun
to design and deploy digital mobile telecommunications networks in competition
with cellular providers. In response to the increased competition, cellular
operators are re-engineering their networks by increasing the number of sites,
locating sites within a smaller radius, filling in "dead zones" and converting
from analog to digital cellular service in order to manage subscriber growth,
extend geographic coverage and provide competitive services. The demand for
communication sites is also being stimulated by the development of new paging
applications, such as e-mail and voicemail notification and two-way paging, as
well as other wireless data applications.

  Licenses are also being awarded, and technologies are being developed, for
numerous new wireless applications that will require networks of communication
sites. These potential applications include the auction of licenses that
occurred in February 1998 for local multi-point distribution services,
including wireless local loop, wireless cable television, data and Internet
access. Radio spectrum required for these technologies has, in many cases,
already been awarded and licensees have begun to build out and offer services
through new wireless systems. Examples of these systems include local loop
networks operated by WinStar and Teligent, wireless cable networks operated by
companies such as Cellular Vision and CAI Wireless, and data networks being
constructed and operated by BellSouth Wireless Data, MTEL and Ardis.

Characteristics of the Tower Industry

  In addition to the increased demand for wireless services and the need to
develop and expand wireless communications networks, we believe that other
trends influencing the wireless communications industry have important
implications for independent tower operators. In this increasingly competitive
wireless industry environment, we believe that many providers are dedicating
their capital and operations primarily to those activities that directly
contribute to subscriber growth, such as marketing and distribution. Many
providers have, therefore, sought to reduce costs and increase efficiency
through the outsourcing of infrastructure network functions such as
communication site ownership, construction, operation and maintenance. Further,
in order to speed new network deployment or expansion and generate
efficiencies, providers are increasingly colocating transmission equipment with
that of other wireless service providers. The trend towards colocation has been
furthered by the "Not-In-My-Backyard" arguments generated by local
zoning/planning authorities in opposition to the proliferation of towers.

  We also believe that, in addition to the favorable growth and outsourcing
trends in the wireless communications industry and barriers to entry as a
result of local zoning restrictions associated with new tower

                                       39
<PAGE>

sites, tower operators benefit from several favorable characteristics. The
ability of tower operators to provide antenna sites to customers on multiple
tenant towers protects them against the specific technology, product and market
risks typically faced by any individual provider. The emergence of new
technologies, providers, products and markets may allow independent tower
operators to further diversify against such risks. We believe that independent
tower operators also benefit from the contract nature of the site leasing
business and the predictability and stability of these recurring revenues. In
addition, the site leasing business has low variable operating costs and
significant operating leverage. Towers generally are fixed cost assets with
minimal variable operating costs associated with additional tenants. A tower
operator can generally expect to experience increasing operating margins when
new tenants are added to existing towers.

  We believe that the site leasing business typically experiences low customer
churn rates as a result of the high costs that would be incurred by a wireless
service provider if it were to relocate an antenna to another site and
consequently be forced to re-engineer its network. Moving a single antenna may
alter the pre-engineered maximum signal coverage, requiring a reconfigured
network at significant cost to maintain the same coverage. Municipal approvals
are increasingly difficult to obtain and may also affect the provider's
decision to relocate. We believe that the costs associated with network
reconfiguration and municipal approval and the time required to complete these
activities are not generally justified by any potential savings in reduced site
leasing expense.

  We are a leading independent owner and operator of wireless communications
infrastructure in the United States. We generate revenues from our two primary
businesses--site leasing and site development services. Since our founding in
1989, we have participated in the development of more than 12,000 antenna sites
in 49 of the 51 major wireless markets in the United States. In 1997, we began
aggressively expanding our site leasing business by capitalizing on our
nationally recognized site development experience and strong relationships with
wireless service providers to take advantage of the trend toward colocation and
independent tower ownership. As of April 30, 1999, we owned or controlled 642
towers, had 51 towers pending acquisition under letters of intent or definitive
agreements and had non-binding mandates to build over 400 additional towers for
anchor tenants. Our Annualized tower cash flow for the first quarter of 1999
was $11.1 million.

  As a result of our extensive existing tower base, we believe we are well-
positioned to continue to capitalize on the growth opportunities available in
the rapidly consolidating and highly fragmented tower leasing industry. We have
used our leadership position in the site development services business, our
existing national field organization and our strong relationships with wireless
service providers to expand into the ownership and leasing of communication
sites. We have added build-to-suit programs and other antenna site leasing
options to our service offerings and have acquired attractive communication
sites. Our build-to-suit programs provide an integrated solution to those
wireless service providers seeking to minimize their capital expenditures,
overhead and time associated with the build-out and on-going maintenance of
their wireless network infrastructure.

  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. We
lease antenna space on: (1) the towers we construct through build-to-suit
programs; (2) existing sites we acquire; (3) the towers we develop
strategically; and (4) sites we lease, sublease and/or manage for third
parties. Under a build-to-suit program, we build a tower for a wireless service
provider who has entered into a long-term anchor tenant lease. We retain
ownership of the tower and the exclusive right to colocate additional tenants
on the tower. We also develop towers strategically, identifying an attractive
location and completing all pre-construction procedures (such as zoning)
necessary to secure the site. We then market the tower site to potential
customers.

  Our site development business consists of site development consulting and
site development construction. Our site development services business is an
"end-to-end" service offering design, construction and operating expertise to a
range of wireless service providers. Our site development services consist of:
(1) network pre-design; (2) communication site selection; (3) communication
site acquisition; (4) local zoning and permitting; and (5) site construction
and antenna installation.

  We have a diverse range of customers, including cellular, PCS, paging, SMR
and ESMR providers, as well as other users of wireless transmission and
reception equipment. Our customers currently include many of the major wireless
communications companies, including AT&T Wireless, BellSouth Mobility DCS,
Nextel, Omnipoint, Pac Bell, PrimeCo, Southwestern Bell and Sprint PCS.

  We will continue to use our site development expertise to complement our site
leasing business, secure additional build-to-suit mandates and choose
acquisitions and strategic sites that we believe will be attractive for future
tenants. We believe that as the site development industry matures, our revenues
and gross profit from the consulting segment of that business will continue to
decline substantially. We also believe that, over the longer term, our site
leasing revenues will increase as carriers move to outsource ownership and
management of towers and as the number of towers we own or control grows as a
result.

Business Strategy

Our strategy is to lease antenna space to multiple tenants on towers that we
construct or acquire. We plan to enhance our position as a leading owner and
operator of communication sites. Key elements of our strategy include:

  .  Maximizing Use of Tower Capacity. We believe that many of our towers
     have or will have significant capacity available for antenna space
     leasing and that increased use of our owned towers can be achieved at
     low incremental cost. We generally construct our towers to accommodate
     multiple tenants in addition to the anchor tenant, and a substantial
     majority of our towers are lattice or guyed towers. We actively market
     space on our own towers through our internal sales force.

  .  Developing New Towers That We Will Own and Operate. As wireless service
     providers increasingly outsource their investment in, and ownership of,
     towers, we can meet their outsourcing needs by using our expertise and
     relationships in the site development business to construct towers with
     anchor tenants through build-to-suit programs. We can also independently
     identify attractive locations for new towers and strategically complete
     pre-construction procedures necessary to secure tower sites in advance
     of customer demand. We believe that we have one of the largest number of
     non-binding build-to-suit mandates from wireless service providers in
     the industry. As of April 30, 1999, we had non-binding mandates to build
     over 400 additional towers under build-to-suit programs for carriers
     including BellSouth Mobility DCS and Sprint PCS. Furthermore, we have in
     varying stages of development over 150 additional sites which we believe
     will be attractive locations for new tower construction. In 1998, we
     built 310 towers.

  .  Acquiring Existing Towers. We believe that our existing national field
     organization gives us a competitive advantage in identifying
     opportunities for the acquisition of existing towers. Our strategy is to
     acquire towers that can service multiple tenants and are attractive to
     wireless service providers based on their location, height and available
     capacity. While we generally target smaller acquisitions, we believe
     that there are many potential acquisition candidates and that the number
     of available towers will grow as large cellular, PCS and other wireless
     service providers divest their tower holdings. We have strict valuation
     criteria and believe that certain tower properties can be purchased at
     reasonable price levels. In 1998, we acquired 135 towers. As of April
     30, 1999, we had letters of intent or definitive agreements with respect
     to pending acquisitions for 51 towers.

  .  Building on Strong Relationships with Major Wireless Service
     Providers. We are well-positioned to be a preferred partner in build-to-
     suit programs because of our strong relationships with wireless service
     providers and proven operating experience. In many cases, the personnel
     awarding site development projects for wireless service providers are
     the same personnel who make decisions with respect to build-to-suit
     programs. We continually market our build-to-suit programs to our site
     development service customers. Our build-to-suit customers include AT&T
     Wireless, BellSouth Mobility DCS, Nextel, PrimeCo PCS, Southwestern
     Bell, Sprint PCS and Western Wireless.

  .  Maintaining our Expertise in Site Development Services. We continue to
     perform an array of site development services for wireless service
     providers across the United States, including AT&T Wireless, BellSouth
     Mobility DCS, Nextel, Pacific Bell Mobile Services, PrimeCo PCS,
     Southwestern Bell, Sprint PCS and Western Wireless. We have a broad
     national field organization that allows us to identify and participate
     in site development projects across the country and that gives us a
     knowledge of local markets and strong customer relationships with
     wireless service providers.

  .  Capitalizing on Management Experience. Our management team has extensive
     experience in site leasing and site development services. Management
     believes that its industry expertise and strong relationships with
     wireless carriers will allow us to continue to build and acquire a high
     quality

                                       42
<PAGE>

     portfolio of towers. Steven E. Bernstein, our President and Chief
     Executive Officer, has more than 12 years of experience in the wireless
     communications industry and our other executive officers have an average
     of approximately five years of experience in this industry. In addition,
     management is highly motivated to produce strong operating results based
     on their approximately 52.5% ownership of our common stock equivalents
     currently outstanding.

Company Services

  We are a leading independent provider of communication sites and services,
offering an array of site leasing and site development services to the
wireless communications industry. We offer our customers the flexibility of
choosing between the provision of a full ready-to-operate site or any of the
component services involved in the operation of a full ready-to-operate site.
The site leasing services we provide include owning, leasing or managing
communication sites and leasing antenna space on communication sites to
wireless service providers. The site development services we provide, directly
or through subcontractors, include all activities associated with the
selection, acquisition and construction of communication sites for wireless
service providers.

Site Leasing Business

The site leasing business consists of:

  .  the ownership of communication sites pursuant to build-to-suit programs,
     strategic builds and acquisitions;

  .  the leasing or subleasing of antenna space on communication sites to
     wireless service providers; and

  .  the maintenance and management of communication sites.

  We lease and sublease antenna space on our communication sites to a variety
of wireless service providers. We own or lease the ground under such
communication sites from third parties, and in some cases manage communication
sites for third parties in exchange for a percentage of the revenues or tower
cash flow. We determine tower cash flow by subtracting from gross tenant
revenues the direct expenses associated with operating the communication site,
such as ground lease payments, real estate taxes, utilities, insurance and
maintenance. The substantial majority of our owned or controlled towers are
the result of build-to-suit programs. In our build-to-suit programs, we use
some or all of the five phases of our site development business as we would
when providing site development services to a third party. After a tower has
been constructed, we lease antenna space on the tower. We generally receive
monthly lease payments from customers payable under written antenna site
leases. The majority of our outstanding customer leases, and the new leases we
typically enter into, have original terms of five years (with four or five
renewal periods of five years each) and usually provide for annual or periodic
price increases. Monthly lease pricing varies with the number and type of
antenna installed on a communication site. Broadband customers such as PCS,
cellular or ESMR generally pay substantially more monthly rent than paging or
other narrowband customers. We also provide a lease/sublease service as part
of our site leasing business whereby we lease space on a communication site
and sublease the space to a wireless service provider.

  Management believes that the site leasing portion of our business has
significant potential for growth and we intend to expand our site leasing
business through increasing activity from our new tower builds and selective
acquisitions. We recently were awarded a non-binding mandate from BellSouth
Mobility DCS to execute all of its outsourced 1999 new tower build-out
(currently expected to be approximately 150 new towers) and also recently were
awarded a non-binding mandate from Sprint PCS to build approximately 100
towers in 1999.

<PAGE>

  In 1998, total capital expenditures associated with the acquisition and
construction of 443 towers were approximately $138.1 million. The following
table indicates the total number of our built and acquired towers as of April
30, 1999:

 Build-to-Suit Programs

  Under our build-to-suit programs, we generally construct towers only after
having signed an antenna site lease agreement with an anchor tenant and having
made the determination that the initial or planned capital investment for those
towers would not exceed a targeted multiple of expected tower cash flow from
those towers after a certain period of time. In selling our build-to-suit
programs, our sales representatives use their existing relationships in the
wireless communications industry to target wireless service providers
interested in outsourcing their network buildout. Our sales representatives
make proposals for build-to-suit towers in

                                       44
<PAGE>

response to competitive bids or specific requests and in circumstances where we
believe the provider would have an interest in build-to-suit towers. Although
the terms vary from proposal to proposal, we typically sign a five-year lease
agreement with an anchor tenant, with four or five additional five-year renewal
periods at the option of the lessee. While the proposed monthly rent also
varies, broadband customers such as PCS, cellular or ESMR generally pay more
than the aggregate monthly rent paid by paging or other narrowband customers.
In addition, anchor tenants will typically pay lower monthly rents than
subsequent tenants of a similar type service. In some cases, an anchor tenant
may also enjoy an introductory lease rate for a period of time.

  If a wireless provider accepts the terms of the proposal submitted by us, the
provider will award us a non-binding mandate to pursue specific sites. Based on
the status of the geographic areas we have been given a mandate to pursue, we
will perform due diligence investigations for a designated period during which
time we will analyze the site based on a number of factors, including
colocation opportunities, zoning and permitting issues, economic potential of
the site, difficulty of constructing a multi-tenant tower and remoteness of the
site. These mandates are non-binding agreements and either party may terminate
the mandate at any time.

  If, after our due diligence investigation during the mandate, we conclude
that it is economically feasible to construct the towers requested by the
wireless service provider, we will enter into an antenna site lease agreement
with the provider. In certain limited circumstances we are contractually
obligated to build a tower for the carrier regardless of the outcome of our due
diligence investigation. We have negotiated several master build-to-suit
agreements, including antenna site lease terms, with providers in specific
markets that we believe will facilitate our obtaining build-to-suit programs
from such providers in those markets. The antenna site lease agreements
typically provide that all obligations are conditioned on our receiving all
necessary zoning approvals where zoning remains to be obtained. Certain of the
antenna site lease agreements contain penalty or forfeiture provisions in the
event the tower is not completed within specified time periods.

 Strategic Siting

  Our strategic siting activities focus on developing new towers in locations
chosen by us, instead of by an anchor tenant in a build-to-suit program. We try
to identify attractive locations for new towers and strategically complete pre-
construction procedures necessary to secure the site in advance of demand from
a specific customer. We may invest in the zoning and permitting of these
strategic sites (and even the construction of the towers) when we have not yet
obtained an anchor tenant if we believe that demand for the site will exist in
the near term, or that a competitor of ours may acquire the site if we wait
until an anchor tenant is secured. However, we generally will not build a tower
on a strategic site until we have signed a lease with a tenant.

 Acquisitions

  We actively pursue acquisitions of communication sites. Our acquisition
strategy, like our new build strategy, is financially-oriented as opposed to
geographically or customer-oriented. Our goal is to acquire towers that have an
initial or planned capital investment not exceeding a targeted multiple of
expected tower cash flow from the acquired towers after a certain period of
time. We determine tower cash flow by subtracting from gross tenant revenues
the direct expenses associated with operating the communication site, such as
ground lease payments, real estate taxes, utilities, insurance and maintenance.

  Our dedicated mergers and acquisitions personnel direct our acquisition
activities and are responsible for identification, negotiation, documentation
and consummation of acquisition opportunities, as well as the coordination and
management of independent advisors and consultants retained by us from time to
time in connection with acquisitions. In addition to our mergers and
acquisitions personnel, we rely on our national field representatives to
identify potential acquisitions. Our field representatives identify generally
smaller acquisition prospects, involving one to ten towers, and often provide
us with the exclusive opportunity to structure and consummate a transaction
with the potential seller. We believe that our field representatives and
knowledge of potential acquisition candidates gained through our substantial
site development business experience provide us with a competitive advantage.
This information will permit us to identify and

                                       45
<PAGE>

consummate acquisitions on more favorable terms than would be available to us
through competitively-bid or brokered acquisition prospects. As is the case
with our new tower builds, our focus is to acquire multi-tenant communication
sites with under-used capacity in locations that we believe will be attractive
to wireless service providers that have not yet built out their service in such
locations.

 Lease/Sublease

  Under our lease/sublease program, we lease antenna space on a communication
site and then sublease the space to wireless service providers. When these
lease/subleases were first signed, these providers chose the financial benefits
associated with the lease/sublease program, which include reduced capital
expenditures, as compared to paying for site development services on a fee
basis. Wireless paging providers comprise a significant majority of customers
who sublease antenna sites from us. The subleases generally have original terms
of five years, with four or five renewal periods of five years each at the
option of the lessee, and usually provide for annual or periodic price
increases.

 Maintenance and Management

  Once acquired or constructed, we maintain and manage our communication sites
through a combination of in-house personnel and independent contractors. We
also manage communication sites for third parties. In-house personnel are
responsible for oversight and supervision of all aspects of site maintenance
and management, and are particularly responsible for monitoring security access
and lighting, RF emission and interference issues, signage, structural
engineering and tower capacity, tenant relations and supervision of independent
contractors. We hire independent contractors locally to perform routine
maintenance functions such as landscaping, pest control, snow removal,
vehicular access, site access and equipment installation oversight. We engage
independent contractors on a fixed fee or time and materials basis or, in a few
limited circumstances where such contractors were sellers of towers to us, for
a percentage of tower cash flow.

  Our network operations center in Boca Raton, Florida centrally monitors
security access and lighting for our towers, as well as other functions. As the
number of communication sites we own and manage increases, we anticipate
incurring greater expenditures to expand our maintenance infrastructure,
including expenditures for personnel and computer hardware and software. We
expect these expenditures to be marginal compared to the anticipated increased
revenues.

Site Development Business

  We offer each phase of our site development services to our customers. These
services and phases are the same ones we employ for our own benefit when we
build towers for our ownership. During Phase I, network pre-design, we perform
pre-design analysis by investigating those geographic areas that are designated
as a priority by our customer. We will then identify, to the extent possible,
all sites that meet the customer's RF requirements in those areas. Mapping
specialists create maps of the sites, analyzing for a number of factors,
including which areas may have the most favorable zoning regulations and
availability of colocation opportunities. Typically, we conduct preliminary
zoning analysis and determine those areas where zoning approval is likely,
along with a possible time frame for approval. We use Phase I services to
eliminate costly redesigns once a project is started, which can result in
significant savings of both time and money.

  In Phase II, site selection, we determine:

  .  which sites most closely meet the RF engineering requirements of the
     customer;

  .  which sites are leasable or can be purchased;

  .  which sites have the potential to be zoned for site construction or
     colocation based on the then current zoning requirements; and

  .  which sites are most suitable for construction and installation of
     antennas.

                                       46
<PAGE>

  Mapping specialists select the most suitable sites based on demographics,
traffic patterns and signal characteristics. Typically, we will identify two or
three potential sites for each location in the RF engineering plan, with the
intent of colocating on an existing site or constructing a new site on the
location most advantageous to the customer. We also seek FAA approval at this
time.

  In Phase III, site acquisition, we secure the right from the property owner
to construct a tower or colocate on the site. Depending on the type of interest
in the property that we believe will best suit the needs of the customer, we
will negotiate and enter into on behalf of the customer:

  .  a contract of sale pursuant to which the customer acquires fee title to
     the property;

  .  a long-term ground or rooftop lease pursuant to which the customer
     acquires a leasehold interest in the property (typically a five-year
     lease with four or five renewal periods of five years each);

  .  an easement agreement pursuant to which the customer acquires an
     easement over the property; or

  .  an option to purchase or lease the property pursuant to which the
     customer has a future right to acquire fee simple title to the property
     or acquire a leasehold interest.

  It is during this phase of the site development service that we generally
obtain a title report on the site, conduct a survey of the site, perform soil
analysis of the site and obtain an environmental survey of the site.

  Phase IV, local zoning and permitting, includes preparing all appropriate
zoning applications and providing representation at any zoning hearings that
may be conducted. We also obtain all necessary entitlement land use permits
necessary to commence construction on the site or install equipment on the
site.

  Phase V, construction and installation, involves the construction management
of the tower on a selected site, whether by the third party or directly by us.
During Phase V, we prepare a construction budget, install or monitor the
installation of equipment and antennas, hire sub-contractors to perform the
actual construction of the tower or equipment installation when not performed
by us, prepare a construction schedule, monitor all vendors' delivery and
installation of equipment and monitor the completion of all construction and
landscaping of the site.

  The acquisition of CSSI, our construction subsidiary, in 1997 provided us
with in-house tower construction and antenna installation capability. CSSI had
extensive experience in the development and construction of tower sites and the
installation of antennas, microwave dishes and electrical and
telecommunications lines, primarily in the southeastern region of the United
States. CSSI's site development and construction services include clearing
sites, laying foundations and electrical and telecommunications lines, and
constructing equipment shelters and towers. CSSI has designed and built tower
sites for a number of its customers and will continue to provide construction
services for third parties. In addition, CSSI has constructed and is expected
to construct a portion of our towers in the future. Through CSSI, we can
provide cost-effective and timely completion of construction projects in part
because its site development personnel are cross-trained in all areas of site
development, construction and antenna installation. CSSI maintains a varied
inventory of heavy construction equipment and materials at its five-acre
equipment storage and handling facility in Ocala, Florida, which is used as a
staging area for projects in the southeastern region of the United States.

  Our site development business is headquartered in Boca Raton, Florida. Once
we are awarded a site development project, we dispatch a site development team
from headquarters to the project site and establish a temporary field office
for the duration of the project. The site development team is typically
composed of our permanent employees and supplemented with local hires employed
only for that particular project. A team leader is assigned to each phase of
the site development project and reports to a project manager who oversees all
team leaders. Upon the completion of a site development project, the field
office is typically closed and all of our permanent employees are either
relocated to another project or directed to return to headquarters.

                                       47
<PAGE>

  We generally set prices for each site development service separately.
Customers are billed for these services on a fixed price or time and materials
basis and we may negotiate fees on individual sites or for groups of sites.

 The Com-Net Acquisition

  On April 30, 1999, we acquired Com-Net Construction Services, Inc. Com-Net
constructs towers and terminal switches on a turn-key basis for wireless and
other telecommunications companies, primarily through the midwestern, eastern
and western United States. Since its inception in 1990, Com-Net has provided
construction and other related services on over 2,000 tower sites, ranging from
turn-key tower construction to the installation of antennas. Clients of Com-Net
include AT&T, BellSouth Cellular Corp., GTE and Sprint. For the year ended
December 31, 1998, Com-Net had revenues of over $20.0 million and gross profit
of $2.2 million. Dan Eldridge, the founder and President of Com-Net, will
continue as President of Com-Net subsequent to the acquisition. We intend for
Com-Net to continue to provide construction services to wireless carriers and
other telecommunications companies, and to build towers for our ownership. At
closing, we issued 780,000 shares of our Class A common stock to the
shareholders of Com-Net (480,000 of which were pledged to us and will be
returned to us if certain earnings targets are not met) and assumed working
capital debt of approximately $4.5 million. In addition, the shareholders of
Com-Net may receive up to $2.5 million in cash and 320,000 additional shares of
Class A common stock if certain 1999 earnings targets are met by the acquired
entity, and up to an additional 400,000 shares of Class A common stock if
certain 2000 earnings targets are met.

  In connection with the Com-Net acquisition, we acquired an affiliate of Com-
Net that owns 15 completed towers located in Texas, Ohio and Tennessee and over
30 additional tower sites in various stages of development under build-to-suit
programs for a purchase price of $1.0 million in cash and assumed debt of
approximately $2.5 million.

Customers

  Since commencing operations, we have performed site leasing and site
development services for many of the largest wireless service providers. The
majority of our contracts have been for PCS broadband, ESMR, cellular and
paging customers. We also serve PCS narrowband, SMR, multichannel multipoint
distribution service, or MMDS, and multipoint distribution service, or MDS,
wireless providers. In both our site development and site leasing businesses,
we work with large national providers and smaller local, regional or private
operators. In 1998, our largest site development customers were Sprint PCS,
BellSouth Mobility DCS and Pacific Bell Mobile Services, representing 41.3%,
23.8% and 13.5%, respectively, of our 1998 site development revenue. PageNet
represented 33.4% of our site leasing revenue. These revenues come primarily
from our lease/sublease component of our site leasing business. Our other major
site leasing customers were Sprint PCS, BellSouth Mobility DCS and AT&T,
representing 6.3%, 2.6% and 1.4%, respectively, of our 1998 site leasing
revenue. No other customer represented more than 10.0% of our revenues.

  In 1997 or 1998, we provided services for a number of customers, including:

Sales and Marketing

  Our sales and marketing goals are:

  .  to continue to grow our site leasing business;

  .  to further cultivate existing customers to obtain mandates for build-to-
     suit programs as well as to sell site development services;

  .  to use our contacts and industry knowledge to better identify attractive
     locations for new tower builds;

  .  to use existing relationships and develop new relationships with
     wireless service providers to lease antenna space on our owned or
     managed communication sites;

  .  to form affiliations with select communications systems vendors who use
     end-to-end services, including those provided by us, which will enable
     us to market our services and product offerings through additional
     channels of distribution; and

  .  to sustain a market leadership position in the site development
     business.

  Historically, we have capitalized on the strength of our experience,
performance and relationships with wireless service providers to position
ourselves for additional site development business. We have leveraged these
attributes to obtain build-to-suit mandates, and we expect to continue to do so
in the future. We also use these attributes to identify attractive locations to
build towers on strategic sites.

  We have a dedicated sales force which is supplemented by members of our
executive management team. Our salespeople are based regionally as well as in
the corporate office. Our senior management focuses on maintaining and
cultivating relationships with wireless service providers. Our strategy is to
delegate sales efforts to those employees of ours who have the best
relationships with the wireless service providers. We assign our
representatives specific accounts based on historical experience with a
provider and the quality of the relationship between our representative and the
provider. Most wireless service providers have national corporate headquarters
with regional offices. We believe that most decisions for site development and
site leasing services are made by providers at the regional level with input
from their corporate headquarters. Our sales representatives work with provider
representatives at the local level and at the national level when appropriate.
Our sales staff compensation is heavily weighted to incentive-based goals and
measurements. In addition to our marketing and sales staff, we rely upon our
executive and operations personnel on the national and field office levels to
identify sales opportunities within existing customer accounts, as well as
acquisition opportunities.

  Our primary marketing and sales support is centralized and directed from our
headquarters office in Boca Raton, Florida and is supplemented by our regional
offices. We have a full-time staff dedicated to our marketing efforts. The
marketing and sales support staff are charged with implementing our marketing
strategies, prospecting and producing sales presentation materials and
proposals.

Competition

  We compete for site leasing tenants with:

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

  .  site development companies that acquire antenna space on existing towers
     for wireless service providers, manage new tower construction and
     provide site development services;

  .  other large independent tower companies; and

  .  smaller local independent tower operators.

                                       49
<PAGE>

Wireless service providers that own and operate their own tower networks
generally are substantially larger and have greater financial resources than we
do. We believe that tower location and capacity, price, quality of service and
density within a geographic market historically have been and will continue to
be the most significant competitive factors affecting the site leasing
business. We also compete for development and new tower construction
opportunities with wireless service providers, site developers and other
independent tower operating companies and believe that competition for site
development will increase and that additional competitors will enter the tower
market, some of which may have greater financial resources than we do.

  The following is a list of our primary competitors for build-to-suit mandates
and tower acquisitions: American Tower Corporation, Crown Castle International
Corp., LCC International, Lodestar Communications, Motorola, Pinnacle Tower,
SpectraSite, Unisite and WesTower.

  We believe that the majority of our competitors in the site development
business operate within local market areas exclusively, while some firms appear
to offer their services nationally, including American Tower Corporation,
Bechtel, Black & Veach, Mastec, NLS, Pyramid, SpectraSite and WesTower. 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 providers' internal staff. We believe that providers base
their decisions on site development services on a number of criteria, including
a company's experience, track record, local reputation, price and time for
completion of a project. We believe that we compete favorably in these areas.

Employees

  As of March 31, 1999, we had 320 employees, none of whom is represented by a
collective bargaining agreement. We consider our employee relations to be good.
Due to the nature of our business, we experience a "run-up" and "run-down" in
the number of employees as contracts are completed in one area of the country
and are commenced in a different area.

Properties

  We are headquartered in Boca Raton, Florida, where we currently lease
approximately 32,000 square feet of space. We open and close project offices
from time to time in connection with our site development business, which
offices are generally leased for periods not to exceed 18 months. We have
entered into longer leases in Atlanta, Boston and Milwaukee, which are regional
office locations.

Legal Proceedings

  From time to time, we are involved in various legal proceedings relating to
claims arising in the ordinary course of business. We are not a party to any
such legal proceeding, the adverse outcome of which, individually or taken
together with all other legal proceedings, is expected to have a material
adverse effect on our prospects, financial condition or results of operations.

Regulatory and Environmental Matters


  Federal Regulations. Both the FCC and FAA regulate towers used for wireless
communications transmitters and receivers. These regulations control the siting
and marking of towers and may, depending on the characteristics of particular
towers, require prior approval and registration of tower facilities. Wireless
communications devices operating on towers are separately regulated and
independently licensed based upon the particular frequency used.

  Pursuant to the requirements of the Communications Act of 1934, the FCC, in
conjunction with the FAA, has developed standards to consider proposals for new
or modified antennas. These standards mandate that the

                                       50
<PAGE>

FCC and the FAA consider the height of proposed antennas, the relationship of
the structure to existing natural or man-made obstructions and the proximity of
the antennas to runways and airports. Proposals to construct or to modify
existing antennas above certain heights are reviewed by the FAA to ensure the
structure will not present a hazard to aviation. The FAA may condition its
issuance of a no-hazard determination upon compliance with specified lighting
and/or marking requirements. The FCC will not license the operation of wireless
telecommunications devices on towers unless the tower has been registered with
the FCC or a determination has been made that such registration is not
necessary. The FCC will not register a tower unless it has been cleared by the
FAA. The FCC may also enforce special lighting and painting requirements.
Owners of wireless transmissions towers may have an obligation to maintain
painting and lighting to conform to FCC standards. Tower owners also bear the
responsibility of notifying the FAA of any tower lighting outage. We generally
indemnify our customers against any failure to comply with applicable
regulatory standards. 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 new law, however,
limits local zoning authority by prohibiting any action that would (1)
discriminate between different providers of personal wireless services or (2)
ban altogether the construction, modification or placement of radio
communication towers. Finally, the 1996 Telecom Act 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.

  Owners and operators of antennas may be subject to, and therefore must comply
with, environmental laws. The FCC's decision to license a proposed tower may be
subject to environmental review pursuant to the National Environmental Policy
Act of 1969, which requires federal agencies to evaluate the environmental
impacts of their decisions under certain circumstances. The FCC has issued
regulations implementing the National Environmental Policy Act. These
regulations place responsibility on each applicant to investigate any potential
environmental effects of operations and to disclose any significant effects on
the environment in an environmental assessment prior to constructing a tower.
In the event the FCC determines the proposed tower 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. This process
could significantly delay the registration of a particular tower.

  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
damages. We are also subject to certain environmental laws that govern tower
placement, including pre-construction environmental studies. Operators of
towers must also take into consideration certain RF emissions regulations that
impose a variety of procedural and operating requirements. The potential
connection between RF emissions and certain negative health effects, including
some forms of cancer, has been the subject of substantial study by the
scientific community in recent years. To date, the results of these studies
have been inconclusive. We believe that we are in substantial compliance with
and we have no material liability under all 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 and leasing activities. Where required, we conduct the site
acquisition portions of our site development services business through licensed
real estate brokers or agents, who may be our employees or hired as independent
contractors. Local regulations include city and other local ordinances, zoning
restrictions and restrictive covenants imposed by community developers. These
regulations vary greatly, but typically require tower owners to obtain approval
from local officials or community standards organizations prior to tower
construction. Local zoning authorities generally have been hostile to
construction of new transmission towers in their communities because of the
height and visibility of the towers.

employment by us without cause, we will pay an amount equal to the aggregate
present value of the product of the base annual salary paid to Mr. Bizick by us
multiplied by 2.0. The agreement also provides for noncompetition,
nonsolicitation and nondisclosure covenants.

Compensation of Directors

  We reimburse our four outside directors for expenses incidental to attendance
at meetings of the Board of Directors. Prior to the offering, each of Messrs.
Miller and Picow received options to purchase 100,000 shares of Class A common
stock, at an exercise price of $2.63 per share upon their election to the Board
of Directors, and those options vest over three years from the date of grant.
After the consummation of the offering, any new directors will be compensated
under the 1999 Equity Participation Plan. See "1999 Equity Participation Plan--
Independent Directors." In addition, Richard W. Miller and Robert S. Picow each
receives compensation for his services as our director and consultant. Mr.
Miller and Mr. Picow each receives $1,000 per Board meeting for attendance at
such meetings, and $1,000 per day for consulting, plus expenses.

1996 Stock Option Plan

  Pursuant to the 1996 Stock Option Plan, options to purchase an aggregate of
1,272,452 shares of Class A common stock in the form of both nonqualified stock
options and incentive stock options, were granted to our directors, key
employees and consultants. A total of 1,800,000 shares of Class A common stock
was reserved for issuance under this option plan. As of March 31, 1999, options
to acquire 1,164,300 shares were issued and outstanding, with an exercise price
of $2.63 per share and options to acquire 105,719 shares were issued and
outstanding with an exercise price of $4.00 per share. These options generally
vest over three-year periods from the date of grant. Pursuant to a resolution
by our board of directors, no new options may be granted under this option
plan.

<PAGE>

1999 Equity Participation Plan

  In 1999, our Board of Directors approved the creation of the 1999 Equity
Participation Plan of SBA Communications Corporation, which we also refer to as
the Equity Plan. A total of 2,500,000 shares of Class A common stock are
reserved for issuance under this option plan. The principal purposes of the
Equity Plan are to provide incentives for our officers, employees and
consultants through granting of options, restricted stock and other awards,
thereby stimulating their personal and active interest in our development and
financial success, and inducing them to remain in our employ. The Equity Plan
is also intended to assist us in attracting and retaining qualified independent
directors (that is, directors who are not employed by us), by providing for the
automatic grant of options to independent directors. In April 1999, we granted
to our executive officers and other employees options to purchase an aggregate
of approximately 900,000 shares of Class A common stock at an exercise price of
$8.00 per share, which vest in three installments commencing December 31, 1999
and ending on April 19, 2002.

  Under the Equity Plan, not more than 2,500,000 shares of Class A common stock
(subject to antidilution and other adjustment provisions) are authorized for
issuance upon exercise of options, stock appreciation rights (which we also
refer to as SARs), and other awards, or upon vesting of restricted or deferred
stock awards. Furthermore, the maximum number of shares which may be subject to
options, SARs, restricted stock or other awards granted under the Equity Plan
to any individual in any calendar year cannot exceed 500,000 (subject to
antidilution and other adjustment provisions).

  The principal features of the Equity Plan are summarized below, but the
summary is qualified in its entirety by reference to the Equity Plan, which is
filed as an exhibit to the registration statement of which this prospectus is a
part.

 Administration

  Prior to our initial registration of Class A common stock under Section 12 of
the Exchange Act, our Board of Directors will administer the Equity Plan.
Following such registration, the compensation committee or another committee or
subcommittee appointed under the terms of the Equity Plan (which we refer to as
the Committee) which other committee or subcommittee consists solely of two or
more members of the Board, each of whom is both a "non-employee director" for
purposes of Rule 16b-3 under the Exchange Act and an "outside director" for the
purposes of Section 162(m) of the Code, will administer the Equity Plan with
respect to grants to our employees or consultants and the full Board will
administer the Equity Plan with respect to options granted to independent
directors.

  Notwithstanding the foregoing, the full Board may administer the Equity Plan
with respect to grants to our employees or consultants, except with respect to
matters which under Rule 16b-3 or Section 162(m) of the Code are required to be
determined by the Committee.

  Subject to the terms and conditions of the Equity Plan, the Committee has the
authority to select the employees and consultants, if any, to whom awards are
to be made, to determine the number of shares to be subject thereto and the
terms and conditions thereof, and to make all other determinations and to take
all other actions necessary or advisable for the administration of the Equity
Plan with respect to grants or awards made to employees or consultants. The
Committee (and the Board) is also authorized to adopt, amend and rescind rules
relating to the administration of the Equity Plan. Notwithstanding the
foregoing, the Board shall conduct the general administration of the Equity
Plan with respect to options granted to independent directors.

 Eligibility

  Options, SARs, restricted stock and other awards under the Equity Plan may be
granted to individuals who are our employees or consultants (or employees or
consultants of any current or future subsidiaries of SBA) selected by the
Committee for participation in the Equity Plan. In addition, the Equity Plan
provides for certain automatic grants of non-qualified stock options to
independent directors.

                                       57
<PAGE>

 Independent Directors

  The Equity Plan provides for automatic grants of non-qualified stock options
to purchase 50,000 shares of Class A common stock to each independent director
who is initially elected to the Board after April 19, 1999, with a per share
exercise price equal to the fair market value per share at the date of grant.
Each such option will become exercisable in cumulative annual installments of
one-fifth each on each of the first five anniversaries of the date of the grant
so long as the independent director continues to serve as our director;
provided, however, to the extent permitted by Rule 16b-3, the Board of
Directors may accelerate the exercisability of options upon the occurrence of
certain specified extraordinary corporate transactions or events. No portion of
an option granted to any independent director shall be exercisable after the
tenth anniversary of the date of grant or after the termination of the
independent director's services as our director. In addition to providing for
automatic option grants to independent directors first elected to the Board
after April 19, 1999, the Equity Plan provides that the Board may, in its
discretion, make additional option grants to independent directors from time to
time. The terms of each option granted to independent directors will be set
forth in a written agreement between us and the independent director.

 Awards under the Equity Plan

  The Equity Plan provides that the Committee may grant or issue stock options,
SARs, restricted stock, deferred stock, dividend equivalents, performance
awards, stock payments, and other stock related benefits, or any combination
thereof to any eligible employee or consultant. Each such award will be set
forth in a separate agreement with the person receiving the award and will
indicate the type, terms and conditions of the award.

  Nonqualified Stock Options, which we also refer to as NQSOs, will provide for
the right to purchase Class A common stock at a specified price which, except
with respect to NQSOs intended to qualify as performance-based compensation
under Section 162(m) of the Internal Revenue Code, may be less than fair market
value on the date of grant (but not less than par value), and usually will
become exercisable (in the discretion of the Committee) in one or more
installments after the grant date, subject to the participant's continued
employment with us and/or subject to the satisfaction of individual performance
targets established by the Committee. NQSOs may be granted for any term
specified by the Committee. Notwithstanding the foregoing, NQSOs granted to
independent directors shall be subject to the terms described above.

  Incentive Stock Options, which we also refer to as ISOs, will be designed to
comply with certain restrictions contained in the Internal Revenue Code. Among
such restrictions, ISOs: (1) must have an exercise price not less than the fair
market value of a share of Class A common stock on the date of grant, (2) may
only be granted to employees, (3) must expire within a specified period of time
following the optionee's termination of employment, and (4) must be exercised
within ten years after the date of grant; but may be subsequently modified to
disqualify them for treatment as ISOs. In the case of an ISO granted to an
individual who owns (or is deemed to own) at least 10% of the total combined
voting power of all of our classes of stock, the Equity Plan provides that the
exercise price must be at least 110% of the fair market value of a share of
Class A common stock on the date of grant and the ISO must expire upon the
fifth anniversary of the date of its grant.

  Restricted Stock may be sold to participants at various prices (but not below
par value) and made subject to such restrictions as may be determined by the
Committee. Restricted stock, typically, may be repurchased by us at the
original purchase price if the conditions or restrictions are not met. In
general, restricted stock may not be sold, or otherwise transferred, until
restrictions are removed or expire. Purchasers of restricted stock, unlike
recipients of options, will have voting rights and will receive dividends prior
to the time when the restrictions lapse.

  Deferred Stock may be awarded to participants, subject to vesting conditions
based on continued employment or on performance criteria established by the
Committee. Like restricted stock, deferred stock may not be sold, or otherwise
transferred, until vesting conditions are removed or expire. Unlike restricted
stock, deferred stock will not be issued until the deferred stock award has
vested, and recipients of deferred stock generally will have no voting or
dividend rights prior to the time when vesting conditions are satisfied.

                                       58
<PAGE>

  Stock Appreciation Rights may be granted in connection with stock options or
other awards, or separately. SARs granted by the Committee in connection with
stock options or other awards typically will provide for payments to the holder
based upon increases in the price of Class A common stock over the exercise
price of the related option or other awards. Except as required by Section
162(m) of the Internal Revenue Code with respect to any SAR intended to qualify
as performance-based compensation as described in Section 162(m) of the
Internal Revenue Code, there are no restrictions specified in the Equity Plan
on the amount of gain realizable from the exercise of SARs, although
restrictions may be imposed by the Committee in the SAR agreements. The
Committee may elect to pay SARs in cash or in Class A common stock or in a
combination of both.

  Dividend Equivalents represent the value of the dividends per share paid by
us, calculated with reference to the number of shares covered by the stock
options, SARs or other awards held by the participant. These dividend
equivalents may be paid in cash or in shares of Class A common stock or in a
combination of both.

  Performance Awards may be granted by the Committee on an individual or group
basis. Generally, these awards will be based upon specific performance targets
and may be paid in cash or in shares of Class A common stock or in a
combination of both. Performance Awards may include "phantom" stock awards that
provide for payments based upon increases in the price of our Class A common
stock over a predetermined period. Performance Awards may also include bonuses
which may be granted by the Committee on an individual or group basis and which
may be payable in cash or in Class A common stock or in a combination of both.

  Stock Payments may be authorized by the Committee in the form of shares of
Class A common stock or an option or other right to purchase Class A common
stock as part of a deferred compensation arrangement or otherwise in lieu of or
in addition to all or any party of compensation, including bonuses, that would
otherwise be payable in cash to the employee or consultant.

Securities Laws and Federal Income Taxes

  Securities Laws. The Equity Plan is intended to conform to the extent
necessary with all provisions of the Securities Act and the Exchange Act and
any and all regulations and rules promulgated by the SEC thereunder, including,
without limitation, Rule 16b-3. To the extent permitted by applicable law, the
Equity Plan and options or other awards granted thereunder shall be deemed
amended to the extent necessary to conform to such laws, rules and regulations.

  General Federal Tax Consequences. Under current federal laws, in general,
recipients of awards and grants of nonqualified stock options, stock
appreciation rights, restricted stock, deferred stock, dividend equivalents,
performance awards, and stock payments under the Equity Plan are generally not
taxable at the time of grant but are taxable under Section 83 of the Internal
Revenue Code upon their receipt of Class A common stock or cash with respect to
the exercise or vesting of such awards or grants and, subject to Section 162(m)
of the Internal Revenue Code, we will be entitled to an income tax deduction
with respect to the amounts taxable to these recipients. Under Sections 421 and
422 of the Internal Revenue Code, recipients of ISOs are generally not taxable
at the time of grant or on their receipt of Class A common stock upon their
exercises of ISOs if the ISOs and option stock are held for certain minimum
holding periods and, in such event, we are not entitled to income tax
deductions with respect to such exercises.

  Section 162(m) Limitation. In general, under Section 162(m) of the Internal
Revenue Code, income tax deductions of publicly-held corporations may be
limited to the extent total compensation (including base salary, annual bonus,
stock option exercises and non-qualified benefits paid) for certain executive
officers exceeds $1 million in any one year. However, under Section 162(m), the
deduction limit does not apply to certain "performance-based compensation"
established by an independent compensation committee which is adequately
disclosed to, and approved by, stockholders. In particular, stock options and
SARs will satisfy the "performance-based compensation" exception if the awards
are made by a qualifying compensation

                                       59
<PAGE>

committee, the plan sets the maximum number of shares that can be granted to
any person within a specified period and the compensation is based solely on an
increase in the stock price after the grant date (that is, the option exercise
price is equal to or greater than the fair market value of the stock subject to
the award on the grant date). Under an Internal Revenue Code Section 162(m)
transition rule for compensation plans of corporations which are privately held
and which become publicly held in an initial public offering, the Equity Plan
will not be subject to Section 162(m) until the transition date, which is the
earliest of (1) the material modification of the Equity Plan; (2) the issuance
of all common stock and other compensation that has been allocated under the
Equity Plan; or (3) the first meeting of shareholders at which directors are to
be elected that occurs after December 31, 2002. After this transition date,
rights and awards granted under the Equity Plan, other than options and SARs,
will not qualify as "performance-based compensation" for purposes of Section
162(m) unless such rights and awards are granted or vest upon preestablished
objective performance goals, the material terms of which are disclosed to and
approved by our shareholders.

  We have attempted to structure the Equity Plan in such a manner that, after
the transition date discussed above, subject to obtaining shareholder approval
of the Equity Plan, the remuneration attributable to stock options and SARs
which meet the other requirements of Section 162(m) will not be subject to the
$1,000,000 limitation. We have not, however, requested a ruling from the IRS or
an opinion of counsel regarding this issue.

1999 Stock Purchase Plan

  In 1999, our Board of Directors adopted the 1999 Stock Purchase Plan, or the
Purchase Plan. The Purchase Plan is intended to be an "employee stock purchase
plan" as described in Section 423 of the Code. The Purchase Plan is
administered by the compensation committee of our Board of Directors. A total
of 500,000 shares of Class A common stock are reserved and available for
purchase under the Purchase Plan, subject to antidilution and other adjustment
provisions.

  The Purchase Plan permits eligible employee participants to purchase Class A
common stock through payroll deductions at a price per share which is equal to
the lesser of eighty-five percent (85%) of the fair market value of the Class A
common stock on the first or the last day of an offering period. The Purchase
Plan provides for two offering periods each calendar year. The first is January
1 through June 30 and the second is July 31 through December 31, except that
the first offering period under the Purchase Plan will begin on September 1,
1999. On the last day of each offering period, each participant's accrued
payroll deductions are automatically applied to the purchase of Class A common
stock.

  Employees eligible to participate in the Purchase Plan consist of all persons
employed for at least 90 days by us or by certain of our subsidiaries described
in the Purchase Plan, except that the Purchase Plan excludes from participation
any employee whose customary employment is for less than 20 hours per week or
for not more than 5 months during a calendar year and any employee who owns
stock representing 5% or more of the total combined voting power or value of
all classes of our stock or the stock of our subsidiaries. No participant may
purchase shares of Class A common stock in any calendar year under the Purchase
Plan with an aggregate fair market value (generally determined as of the
beginning of the plan year) in excess of $25,000.

                              CERTAIN TRANSACTIONS

  Steven M. Bernstein, our President and Chief Executive Officer, is indebted
to us in the amount of $3,839,930, including accrued interest as of March 31,
1999. The indebtedness was incurred in March 1997 in the principal amount of
$3.5 million, accrues interest at 4.67% per annum and is secured by 823,530
shares of Mr. Bernstein's Class B common stock. The debt matures on the earlier
of March 2001 or the completion of an initial public offering of our common
stock. Upon the consummation of the offering, Mr. Bernstein will surrender
shares of Class B common stock to SBA, valued at the initial offering price for
Class A common stock, in order to repay the loan and all accrued interest on
the loan.

  We, on occasion, have employed the services of Traveleze, a travel agent that
uses the services of Skylink, a corporation owned by the wife of Ronald G.
Bizick II, our Executive Vice President--Sales and Marketing. Traveleze paid
commissions to Skylink during 1998 as a result of such transactions based on
terms that are customary in the industry aggregating less than $100,000.

                          DESCRIPTION OF CAPITAL STOCK

  The following summary of the terms and provisions of our capital stock is not
complete and is qualified in its entirety by reference to our Amended and
Restated Articles of Incorporation, which have been filed as an exhibit to the
registration statement of which this prospectus is a part.

  As of April 1, 1999, our outstanding capital stock consisted of 880,922
shares of Class A common stock, 8,075,000 shares of Class B common stock, and
8,050,000 shares of Series A preferred stock. No other shares of any class or
series were issued and outstanding as of April 1, 1999. In addition, (1)
1,800,000 shares of Class A common stock were reserved for issuance upon the
exercise of outstanding stock options that were granted under the 1996 Stock
Option Plan, (2) 2,500,000 shares of Class A common stock were reserved for
issuance upon the exercise of stock options granted or to be granted under the
1999 Equity Participation Plan, (3) 8,050,000 shares of Series B preferred
stock were reserved for issuance upon conversion of the outstanding shares of
Series A preferred stock, (4) 8,050,000 shares of Class A common stock were
reserved for issuance upon conversion of outstanding shares of Series A
preferred stock, (5) 402,500 shares were reserved for issuance upon exercise of
an outstanding warrant granted to BT Alex. Brown in connection with the
offering of Series A preferred stock, (6) 500,000 shares of Class A common
stock were reserved for issuance under the 1999 Employee Stock Purchase Plan
and (7) 386,764 shares of Class A common stock were reserved for issuance upon
the exercise of stock options held by Mr. Grobstein.

  In connection with the offering, each share of Series A preferred stock will
be automatically converted into one share of Class A common stock, which will
remain outstanding, and one share of Series B preferred stock, which will be
redeemed with a portion of the proceeds from the offering. See "Use of
Proceeds." Also in connection with the offering, we are amending and restating
our articles of incorporation and by-laws. The description that follows gives
effect to these amendments.

  Upon consummation of the offering, our authorized capital stock will consist
of 100,000,000 shares of Class A common stock, par value $.01 per share,
8,100,000 shares of Class B common stock, par value $.01 per share, and
30,000,000 shares of preferred stock, par value $.01 per share. These shares of
preferred stock will not have been designated as to series and will be
available for issuance from time to time in one or more series at the
discretion of our Board of Directors. While we have no present intention to
issue additional shares of preferred stock, any such issuance could be used to
discourage, delay or make more difficult a change in control of SBA.

  We have two classes of authorized common stock: Class A common stock and
Class B common stock. The Class A common stock has one vote per share. The
Class B common stock has ten votes per share. All outstanding shares of Class A
common stock and Class B common stock are validly issued, fully paid and
nonassessable. As of March 31, 1999, there were five holders of all of our
Class A common stock and there was one holder of all of our Class B common
stock.

  Except as otherwise required by law or in our articles of incorporation,
owners of the Class A common stock and Class B common stock will vote together
as a single class on all matters, including the election of directors. Our
articles of incorporation provide, upon the consummation of this offering, for
a separate class vote of each class of common stock in the event of any
amendment that alters the terms of the Class B common stock. Pursuant to our
articles of incorporation and by-laws, our Board of Directors will be
classified into three classes of directors, denoted as Class I, Class II and
Class III. Messrs. Picow and Landry will be Class I directors, Mr. Miller will
be a Class II director, and Messrs. Bernstein and Hebb will be Class III
directors.

Class A Common Stock

 Voting Rights

  Each share of Class A common stock is entitled to one vote. Except as noted
above, and except as provided under the Florida Business Corporation Act, the
holders of shares of Class A common stock and Class B common stock vote
together as a single class on all matters on which shareholders are permitted
or

                                       65
<PAGE>

entitled to vote. All the outstanding shares of Class A common stock are held
by directors, executive officers, other employees and affiliates of ours or our
subsidiaries.

 Dividends

  Each share of Class A common stock is entitled to receive dividends if, as
and when declared by the Board of Directors out of funds legally available for
that purpose, subject to preferences that may apply to any preferred stock that
we may issue in the future. No dividends may be declared and paid to holders of
shares of Class A common stock unless the Board of Directors at the same time
also declares and pays to the holders of Class B common stock a per share
dividend equal to the dividend declared and paid to the holders of shares of
Class A common stock. See "Dividend Policy."

 Liquidation Rights

  In the event of our dissolution or liquidation, after satisfaction of all our
debts and liabilities and distributions to the holders of any preferred stock
that we may issue in the future, if any, of amounts to which they are
preferentially entitled, holders of Class A common stock will be entitled to
share ratably with holders of common stock in the distribution of assets to the
shareholders.

 Other Provisions

  There are no cumulative, subscription or preemptive rights to subscribe for
any additional securities which we may issue, and there are no redemption
provisions, conversion provisions or sinking fund provisions applicable to the
Class A common stock.

Class B Common Stock

 Voting Rights

  Each share of Class B common stock is entitled to ten votes for each share on
all matters presented to the shareholders. Except as provided under the Florida
Business Corporation Act, the holders of the shares of Class B common stock and
Class A common stock vote together as a single class on all matters on which
shareholders are permitted or entitled to vote.

 Dividends

  Each share of Class B common stock is entitled to receive dividends if, as
and when declared by the Board of Directors out of funds legally available for
that purpose, subject to preferences that may apply to any preferred stock that
we may issue in the future. No dividends may be declared and paid to holders of
shares of Class B common stock unless the Board of Directors at the same time
also declares and pays to holders of Class A common stock a per share dividend
equal to the dividend declared and paid to holders of shares of Class B common
stock.

 Liquidation Rights

  In the event of our dissolution or liquidation, after satisfaction of all our
debts and liabilities to creditors and distributions to the holders of any
preferred stock that we may issue in the future, if any, of amounts to which
they are preferentially entitled, holders of Class B common stock will be
entitled to share ratably with holders of common stock in the distribution of
assets available for distribution to the shareholders.

 Convertibility

  Each outstanding share of Class B common stock may, at the option of the
holder thereof, at any time, be converted into one fully paid and non-
assessable share of Class A common stock. Each share of outstanding

                                       66
<PAGE>

Class B common stock shall convert into one fully paid and non-assessable share
of Class A common stock immediately upon transfer to any holder other than any
one or more of the following (an "Eligible Class B Shareholder"): (1) Steven E.
Bernstein; (2) other members of his immediate family or their lineal
descendants; (3) spouses of lineal descendants or lineal descendants of
spouses, whether alive as of the date of the articles of incorporation or born
subsequently; (4) any trusts or other estate planning vehicles for the benefit
of any of the foregoing, whether existing as of the date of the articles of
incorporation or subsequently created; or (5) any estate or tax planning
vehicles on the part of Mr. Bernstein. If the shares of Class B common stock
held by Eligible Class B Shareholders in the aggregate constitute 10% or less
of the outstanding shares of our common stock, or upon the death or mental
incapacity of Steven E. Bernstein, each share of Class B common stock shall
immediately convert into one fully paid and non-assessable share of Class A
common stock. Each share of outstanding Class B common stock which is held by
any Eligible Class B Shareholder shall immediately convert into one share of
Class A common stock at such time as such holder is no longer an Eligible Class
B Shareholder.

 Other Provisions

  There are no cumulative, subscription or preemptive rights to subscribe for
any additional securities that we may issue, and there are no redemption
provisions or sinking fund provisions applicable to the Class B common stock.

  The rights and preferences of holders of both classes of common stock are
subject to the rights of any series of preferred stock which we may issue in
the future.

Warrant

  In connection with the sale of our Series A preferred stock in March 1997, we
issued a warrant to acquire shares of Class A common stock to BT Alex. Brown.
The warrant, (which represents 1.3% of our common stock on a fully diluted
basis as of the closing of the offering, and assuming the exercise of the over-
allotment option in full) when exercised, entitles its holder to receive
402,500 fully paid and non-assessable shares of Class A common stock at an
exercise price of $3.73 per share. The warrant is exercisable at any time on or
before March 2002. The exercise and transfer of the warrant is subject to
applicable federal and state securities laws.

Registration Rights

  If at any time, the holders of not less than 25% of the Class A common stock
issued or issuable upon conversion of our outstanding Series A preferred stock
request that we file a registration statement covering common stock (with an
anticipated aggregate offering price of $15.0 million or more in the case of a
registration which is an initial public offering and $3.0 million for any other
registration), we will use our best efforts to cause such shares to be
registered, subject to certain cut-back provisions; provided, however, that we
may delay any such registration for a period of up to three months for a valid
business reason. We will not be required to file more than three registration
statements, other than on Form S-3. The holders of Series A preferred stock
will have the right to require us to file up to two registration statements per
year on Form S-3, provided the anticipated aggregate offering price in each
registration on Form S-3 equals $1.0 million or more.

  Each of Messrs. Bernstein, Bizick, Grobstein and Stoops also has certain
rights to have his shares of common stock registered under the Securities Act.
Mr. Bernstein has the right to have 8,075,000 shares of Class B common stock
registered under the Securities Act. Mr. Bizick has the right to have 773,528

<PAGE>

  If at any time, Mr. Bernstein, Mr. Bizick, Mr. Grobstein or Mr. Stoops,
individually or as a group, request that we file a registration statement on
Form S-3 for these shares, we will use our best efforts to cause such shares to
be registered subject to certain cut-back provisions; provided, however, that
we may delay any such registration for a period of up to three months for a
valid business reason. We will not be required to file the registration
statement on Form S-3 more frequently than twice a year.

  The holders of Series A preferred stock are entitled to have the shares of
Class A common stock issued upon conversion of the Series A preferred stock
included in each registration statement filed on behalf of SBA or our
shareholders, subject to certain cut-back provisions. Except as otherwise
agreed, in the event of an application of such cut-back provisions, the holders
of Series A preferred stock have a priority right to participate in such
registration over Messrs. Bernstein, Bizick, Grobstein or Stoops.

Preferred Stock

  All shares of our currently outstanding preferred stock will be retired upon
consummation of the offering. Our board of directors will be authorized by our
articles of incorporation to provide for the issuance of new shares of
preferred stock, in one or more series, to establish the number of shares to be
included in each series, to fix the designation, rights, preferences,

                          DESCRIPTION OF EXISTING DEBT

The Senior Credit Facility

  On February 5, 1999, our wholly owned subsidiary, Telecommunications, entered
into a senior credit facility with a group of banks and other financial
institutions led by Lehman Commercial Paper Inc., as administrative agent, and
Lehman Brothers Inc. and General Electric Capital Corporation, as co-arrangers.
Lehman Brothers Inc. is an underwriter in this offering. The following is a
summary of certain provisions of the senior credit facility, but you should
refer to the actual credit agreement, which is filed as an exhibit to the
registration statement of which this prospectus is a part.

  The senior credit facility provides for revolving credit loans of up to
$150.0 million. The senior credit facility also provides for a term loan in the
amount of $25.0 million. Telecommunications borrowed the full $25.0 million of
this term loan on February 5, 1999. We plan to use some of the proceeds of the
offering to repay outstanding revolving credit loans. The senior credit
facility is secured by a lien on substantially all of our assets and the assets
of our domestic subsidiaries and a pledge of all of the outstanding capital
stock of each of our domestic subsidiaries. We, and each of our domestic
subsidiaries (other than Telecommunications) have guaranteed the obligations of
Telecommunications under the senior credit facility.

  The revolving credit commitments are required to be reduced and the term
loans are required to be amortized in quarterly installments beginning on March
31, 2001 until December 31, 2004, when the senior credit facility matures. In
addition, the senior credit facility provides for the mandatory prepayment of
the revolving credit loans and the term loan with the net cash proceeds of (1)
any issuance of equity or incurrence of debt by us or any of our subsidiaries,
subject to certain exceptions, (2) any asset sale by us or any of our
subsidiaries, subject to certain exceptions, (3) any payment received by us or
any of our subsidiaries in respect to any property or casualty insurance claim
and (4) 75% of excess cash flow of Telecommunications commencing with the
fiscal year of Telecommunications ending December 31, 1999.

  The loans under the senior credit facility bear interest, at the option of
Telecommunications, at either (1) a "base rate" equal to the greater of (a) the
rate of interest announced by Bankers Trust Company as its prime rate at its
New York office, (b) the secondary market rate for three-month certificates of
deposit, as adjusted for statutory reserve requirements plus 1.0%, or (c) the
sum of 0.5% plus the federal funds effective rate plus, in each case, a margin
ranging from 1.25% to 2.50% (determined by a leverage ratio), or (2) the rate
at which eurodollar deposits for one, two, three or six months (as selected by
Telecommunications) are offered in the interbank eurodollar market plus a
margin ranging from 2.25% to 3.50% (determined by a leverage ratio). If all or
any portion of the principal amount of any loan is not paid when due, the
applicable interest rate on the overdue amount will increase by 2.0% per year.
If all or any portion of any interest, fees or other amounts is not paid when
due, the overdue amount shall bear interest at 2.0% above the rate applicable
to the base rate loans.

  The senior credit facility contains a number of covenants that, among other
things, restrict our ability, and the availability of each of our subsidiaries,
to dispose of assets, incur additional indebtedness, incur guaranty
obligations, pay dividends or make capital distributions, create liens on
assets, make investments, make acquisitions, engage in mergers or
consolidations, engage in certain transactions with subsidiaries and affiliates
and otherwise restrict corporate activities. In addition, the senior credit
facility requires compliance with certain financial covenants and restricts the
number of towers that may be constructed in advance of securing an anchor
tenant. Prior to August 5, 2001, Telecommunications and its subsidiaries must
maintain a minimum annualized adjusted EBITDA, a minimum ratio of annualized
adjusted EBITDA to interest expense and a minimum amount of revenues from
towers and cannot exceed a maximum amount of total debt per tower, a maximum
ratio of total debt to total capitalization, a maximum amount of total debt to
annualized adjusted EBITDA and a maximum amount of capital expenditures. From
and after August 5, 2001, Telecommunications

                                       69
<PAGE>

and its subsidiaries must maintain a minimum ratio of consolidated EBITDA to
interest expense, a minimum ratio of fixed charges and a minimum ratio of debt
service coverage and cannot exceed a maximum ratio of total debt to EBITDA and
maximum amount of capital expenditures. We do not expect that such covenants
will materially impact our ability to operate our respective businesses.

  The senior credit facility contains customary events of default, including
(1) the failure to pay principal when due, (2) the failure to pay any interest
or any other amount within five days after it becomes due, (3) the material
inaccuracy of any representation or warranty being made by us or any of our
domestic subsidiaries on or as of the date made or deemed made, (4) a default
in the performance of any negative covenant (including any financial covenant),
(5) a default in the performance of other covenants or agreements subject, in
certain cases, to a 30 day grace period, (6) default in certain of our other
indebtedness, (7) certain insolvency events and (8) certain change of control
events. In addition, a default under the indenture governing our senior
discount notes will result in a default under the senior credit facility.

The 12% Senior Discount Notes Due 2008

  On March 2, 1998, we privately placed $269.0 million in aggregate principal
amount at maturity of our 12% senior discount notes due 2008. This description
summarizes certain terms of those notes, but does not describe all of the
terms. You should refer to the indenture governing the notes, a copy of which
has been filed as an exhibit to the registration statement of which this
prospectus is a part.

  The senior discount notes are unsecured senior obligations of SBA, and will
rank equal in right of payment with all existing and future unsecured senior
indebtedness of SBA and will be senior in right of payment to future
subordinated indebtedness of SBA. Our subsidiaries are not guarantors of the
notes. The notes will mature on March 1, 2008. The notes will accrete in value
until March 1, 2003. After that date, cash interest will accrue on the notes at
the rate of 12% per year and will be payable semi-annually, commencing on
September 1, 2003.

  Except as stated below, the notes are not redeemable at our option prior to
March 1, 2004. Thereafter, the notes are redeemable at our option, in whole or
in part, at any time, at a premium which is at a fixed percentage that declines
to par on or after March 1, 2007, in each case together with accrued and unpaid
interest, if any, to the date of redemption. In the event we consummate a
public equity offering or certain strategic equity investments prior to March
1, 2001, we may, at our option, use all or a portion of the proceeds from such
offering to redeem up to 20% of the original aggregate principal amount at
maturity of the notes at a redemption price equal to 112% of the accreted value
of the notes to be redeemed, plus accrued and unpaid interest, if any, thereon
to the redemption date, if at least 80% of the original aggregate principal
amount at maturity of the notes remains outstanding after each such redemption.

  Upon the occurrence of certain change of control events, each holder of notes
has the right to require us to purchase all or a portion of such holder's notes
at a price equal to 101% of the aggregate principal amount thereof, together
with accrued and unpaid interest to the date of purchase or, if the notes are
purchased prior to March 1, 2003, at a purchase price equal to 101% of the
accreted value of the notes on the date of purchase.

  The indenture contains certain covenants, including covenants that limit (1)
the incurrence of certain additional indebtedness and issuance of preferred
stock, (2) restricted payments, (3) distributions from restricted subsidiaries,
(4) transactions with affiliates, (5) sales of assets and subsidiary stock
(including sale and leaseback transactions), (6) dividend and other payment
restrictions affecting restricted subsidiaries, and (7) mergers or
consolidations.

                        SHARES ELIGIBLE FOR FUTURE SALE

  Upon completion of the offering, we will have 28,972,866 shares of common
stock outstanding (including the 7,723,482 shares of Class B common stock to be
outstanding after the offering, the 8,050,000 shares of Class A common stock to
be issued upon the conversion of the Series A preferred stock and the 780,000
shares of Class A common stock issued at the closing of the Com-Net
acquisition). In addition, we have reserved for issuance 4,151,383 shares of
Class A common stock upon exercise of stock options and 402,500 shares of Class
A common stock upon exercise of the outstanding warrant. The 11,538,462 shares
(13,269,231 shares if the over-allotment option is exercised in full) sold in
the offering will be freely transferable without restriction under the
Securities Act, unless they are held by "affiliates" of ours as that term is
used under the Securities Act. Of the remaining 17,434,404 shares (15,703,635
shares if the over-allotment option is exercised in full), 15,773,482 shares
will be freely transferable without restriction under the Securities Act,
unless they are held by our "affiliates" and will be available for public sale
upon expiration of the "lock-up" agreements described below. The remaining
1,660,922 shares will be "restricted securities" as that term is defined in
Rule 144 and subject to the volume restrictions of Rule 144. Substantially all
of these restricted securities are entitled to demand and piggyback
registration rights under certain circumstances.

  We intend to file a registration statement under the Securities Act after the
offering to register shares of Class A common stock reserved for issuance under
the 1996 Stock Option Plan and the 1999 Equity Participation Plan. This
registration would permit the resale of such shares by non-affiliates upon
issuance in the public market without restriction under the Securities Act.
Such registration statement will automatically become effective immediately
upon filing. See "Management."

  In connection with the offering and subject to certain exceptions, we, all of
our executive officers and directors and holders of our Series A preferred
stock have agreed not to sell any shares of Class A common stock, or any
securities which may be converted into or exchanged for any such shares of
Class A common stock or substantially similar securities, for a period of 180
days after the date of this prospectus without the prior written consent of
Lehman Brothers Inc., subject to typical exceptions. In addition, our employees
who will own 10,000 or more vested options during the 180-day period described
above will execute similar "lock-up" agreements. See "Underwriting."

  In general, under Rule 144 as currently in effect, a shareholder, including
an "affiliate," who has beneficially owned his or her restricted securities (as
that term is defined in Rule 144) for at least one year from the later of the
date such securities were acquired from us or, if applicable, the date they
were acquired from an affiliate, is entitled to sell, within any three-month
period, a number of such shares that does not exceed the greater of 1% of the
then outstanding shares of Class A common stock (which will equal approximately
290,269 shares or the average weekly trading volume in the Class A common stock
during the four calendar weeks before the date on which notice of such sale was
filed under Rule 144, provided certain requirements concerning availability of
public information, manner of sale and notice of sale are satisfied. In
addition, under Rule 144(k), if a period of at least two years has elapsed from
the later of the date restricted securities were acquired from us or, if
applicable, the date they were acquired from an affiliate of ours, a
shareholder who is not an affiliate of ours at the time of sale and has not
been an affiliate of ours for at least three months prior to the sale is
entitled to sell the shares immediately without compliance with the foregoing
requirements under Rule 144.

  Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from us by our employees,
directors, officers, consultants or advisors prior to the date we become
subject to the reporting requirements of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), pursuant to written compensatory benefit plans
or written contracts relating to the compensation of these persons. In
addition, the SEC has indicated that Rule 701 will apply to typical stock
options granted by an issuer before it becomes subject to the reporting
requirements of the Exchange Act, along with the shares acquired upon exercise
of these options (including exercises, after the date of this offering).
Securities issued in reliance on Rule 701 are restricted

                                       71
<PAGE>

securities and commencing 90 days after we become subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, subject to the
contractual restrictions described above, may be sold (1) by persons other than
affiliates, subject only to the manner of sale provisions of Rule 144, and (2)
by affiliates, under Rule 144 without compliance with its one-year minimum
holding period requirements.

  Except as indicated above, we are unable to estimate the amount, timing and
nature of future sales of outstanding Class A common stock. Prior to this
offering, there has been no public market for the Class A common stock, and no
prediction can be made as to the effect, if any, that market sales of shares of
Class A common stock or the availability of shares of sale will have on the
market price of the Class A common stock prevailing at any given time.
Nevertheless, sales of significant numbers of shares of Class A common stock in
the public market could adversely affect the market price of the Class A common
stock and could impair our ability to raise capital through an offering of our
equity securities. See "Risk Factors" and "Underwriting".

Registration Rights

  The holders of our outstanding preferred stock, as well as Messrs. Bernstein,
Bizick, Grobstein and Stoops, have certain rights to have their shares of
common stock registered under the Securities Act. See "Description of Capital
Stock --Registration Rights."

  CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

  The following is a general summary of the material United States Federal
income and estate tax considerations to a Non-U.S. Holder (as defined below)
relevant to the ownership and disposition of shares of Class A common stock.
This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), final, temporary and proposed United States Treasury regulations
promulgated thereunder, Internal Revenue Service (the "IRS") rulings, official
pronouncements and judicial decisions, all as in effect on the date hereof and
all of which are subject to change, possibly with retroactive effect, or
different interpretations. This summary does not discuss all the tax
consequences that may be relevant to a particular Non-U.S. Holder in light of
the holder's particular circumstances and it is not intended to be applicable
in all respects to all categories of Non-U.S. Holders, some of whom may be
subject to special rules not discussed below. In addition, this summary does
not address any state, local or foreign tax considerations that may be relevant
to a Non-U.S. Holder's decision to purchase shares of Class A common stock.

  For purposes of this discussion, a "Non-U.S. Holder" means a beneficial owner
of common stock that is not (1) a citizen or resident of the United States, (2)
a corporation or partnership created or organized in or under the laws of the
United States or any political subdivision thereof, (3) an estate the income of
which is subject to United States federal income taxation regardless of its
source and (4) a trust (a) that is subject to the supervision of a court within
the United States and the control of one or more United States persons as
described in section 7701(a)(30) of the Code or (b) that has a valid election
in effect under applicable U.S. Treasury regulations to be treated as a United
States person. An individual may be deemed to be a resident alien (as opposed
to a nonresident alien) by virtue of being present in the United States on at
least 31 days during the calendar year and for an aggregate of at least 183
days during the calendar year and the two preceding calendar years (counting,
for such purposes all the days present in the current year, one-third of the
days present in the immediately preceding year and one sixth of the days
present in the second preceding year). In addition to the "substantial presence
test" described in the immediately preceding sentence, an individual may be
treated as a resident alien if he or she (1) meets the lawful permanent
residence test (a so-called "green card" test) or (2) elects to be treated as a
U.S. resident and meets the "substantial presence test" in the immediately
following year. Generally, resident aliens are subject to U.S. Federal income
and estate tax in the same manner as U.S. citizens and residents.

  ALL NON-U.S. HOLDERS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING
THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE PURCHASE,
OWNERSHIP AND DISPOSITION OF SHARES OF CLASS A COMMON STOCK IN LIGHT OF THEIR
OWN PARTICULAR CIRCUMSTANCES.

Dividends on Common Stock

  Generally, any dividends paid to a Non-U.S. Holder of common stock will be
subject to United States Federal withholding tax at a rate of 30% of the amount
of the dividend, or at a lower applicable income tax treaty rate. However, if
the dividend is effectively connected with the conduct of a United States trade
or business of a Non-U.S. Holder (and is attributable to a U.S. permanent
establishment of such Non-U.S. Holder, if an applicable income tax treaty so
requires as a condition for the Non-U.S. Holder to be subject to U.S. income
tax on a net income basis in respect of such dividends) it will be subject to
United States Federal income tax on a net income basis at ordinary Federal
income tax rates (in which case the "branch profits tax" at 30% (or such lower
rate as may be specified in an applicable income tax treaty) may also apply if
such Non-U.S. Holder is a foreign corporation), and assuming certain
certification requirements are met, will not be subject to the 30% withholding
tax. Certain certification and disclosure requirements must be complied with in
order to be exempt from withholding under such effectively connected income
exemption.

  Under current Treasury regulations, a holder's status as a Non-U.S. Holder
and eligibility for a tax treaty reduced rate of withholding will be determined
by reference to the holder's address and to any outstanding certificates or
statements concerning eligibility for a reduced rate of withholding, unless
facts and

                                       73
<PAGE>

circumstances indicate that reliance on such address, certificates or
statements is not warranted. However, subject to certain transitional rules,
recently issued Treasury regulations require a Non-U.S. Holder to provide
certifications under penalties of perjury in order to obtain treaty benefits
for payments made after December 31, 2000.

  A Non-U.S. Holder of common stock eligible for a reduced rate of United
States withholding tax pursuant to an income tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
IRS.

Disposition of Common Stock

  Subject to the discussion of backup withholding below, any capital gain
realized upon a sale or other disposition of common stock by a Non-U.S. Holder
ordinarily will not be subject to United States Federal income tax unless (1)
such gain is effectively connected with a trade or business conducted by such
Non-U.S. Holder within the United States (and is attributable to a U.S.
permanent establishment of such holder, if an applicable income tax treaty so
requires as a condition for the Non-U.S. Holder to be subject to U.S. income
tax on a net income basis in respect of such gain) (in which case the branch
profits tax at 30% of the Non-U.S. Holder's effectively connected earnings and
profits within the meaning of the Code for the taxable year, as adjusted for
certain items, (or such lower rate as may be specified in an applicable income
tax treaty) may also apply, in addition to tax on the net gain derived from the
sale under regular graduated United States federal income tax rates, if the
Non-U.S. Holder is a foreign corporation), (2) in the case of a Non-U.S. Holder
that is an individual who holds the common stock as a capital asset, such Non-
U.S. Holder is present in the United States for a period or periods aggregating
183 days or more in the taxable year of the sale or other disposition and
either (a) has a "tax home" for Federal income tax purposes in the United
States or (b) has an office or other fixed place of business in the United
States to which the gain is attributable (in which case such holder will be
subject to a flat 30% tax on the gain derived from the sale, which may be
offset by United States source capital losses (even though the individual is
not considered a resident of the United States)), or (3) we are or have been a
"United States real property holding corporation" (a "USRPHC") for Federal
income tax purposes within the lesser of (a) the five-year period ending on the
date of the sale or other disposition and (b) the Non-U.S. Holder's holding
period, and, in each case, no income tax treaty exception is applicable. We
believe that we are currently a USRPHC. However, any gain recognized by a Non-
U.S. Holder on the disposition of the common stock still would not be subject
to U.S. tax if the common stock were to be "regularly traded" (within the
meaning of applicable Treasury regulations) on an established securities market
(such as, for example, the Nasdaq Stock Market) and the Non-U.S. Holder did not
own, directly or constructively, more than 5% of the outstanding common stock
at any time during the shorter of (a) the five-year period ending on the date
of the sale or other disposition and (b) the Non-U.S. Holder's holding period.
We believe that upon the consummation of the offering the common stock will be
"regularly traded" (within the meaning of applicable Treasury regulations) on
an established securities market. Non-U.S. Holders should consult their tax
advisors to determine whether an income tax treaty is applicable.

  Special rules may apply to certain Non-U.S. Holders, such as "controlled
foreign corporations", "passive foreign investment companies" and "foreign
personal holding companies", that are subject to special treatment under the
Code. Such entities should consult their own tax advisors to determine the U.S.
federal, state, local and other tax consequences that may be relevant to them.

Federal Estate Taxes

  Common stock that is beneficially owned by an individual Non-U.S. Holder at
the time of death will be included in such individual's gross estate for United
States Federal estate tax purposes, unless an applicable estate tax treaty
provides otherwise.

Backup Withholding and Information Reporting

  Under current law, dividends on common stock paid to a Non-U.S. Holder at an
address outside the United States will generally be exempt from backup
withholding tax (unless the payer has knowledge that the
payee is a U.S. person). Under United States Treasury regulations, however,
backup withholding of United

                                       74
<PAGE>

States Federal income tax at a rate of 31% may apply to dividends paid with
respect to common stock to Non-U.S. Holders that fail to provide certain
information (including the holder's taxpayer identification number) in the
manner required by United States law and applicable regulations.

  Payments of the proceeds from the sale by a Non-U.S. Holder of shares of
common stock made by or through a foreign office of a broker will not be
subject to information reporting or backup withholding except that if the
broker is, for United States tax purposes, a United States person, a controlled
foreign corporation or a foreign person 50% or more of whose gross income is
effectively connected with the conduct of a United States trade or business for
a specified three-year period, information reporting may apply to such
payments. Payments of the proceeds from the sale of shares of common stock by
or through the United States office of a broker will be subject to information
reporting and backup withholding unless the Non-U.S. Holder certifies under
penalties of perjury that it is a Non-U.S. Holder or otherwise establishes an
exemption from information reporting and backup withholding. Subject to certain
transitional rules, recently adopted Treasury regulations change information
reporting requirements for Non-U.S. Holders for payments made after December
31, 2000. Accordingly, a Non-U.S. Holder should consult its tax advisor
regarding the effects on it, if any, of these new regulations.

  Any amounts withhold under the backup withholding rules may be allowed as a
refund or a credit against such Non-U.S. Holder's U.S. federal income tax
liability provided the required information is furnished to the IRS.

</TABLE>

  The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in the offering are subject to
approval of legal matters by counsel as well as to other conditions. The
underwriters are obligated to purchase all the shares (other than those covered
by the over-allotment option described below) if they purchase any of the
shares.

  The underwriters propose to offer some of the shares directly to the public
at the public offering price set forth on the cover page of this prospectus and
some of the shares to certain dealers at the public offering price less a
concession not in excess of $        per share. The underwriters may allow, and
such dealers may reallow, a concession not in excess of $        per share on
sales to certain other dealers. If all of the shares are not sold at the
initial offering price, the representatives may change the public offering
price and the other selling terms. The representatives have advised us that the
underwriters do not intend to confirm any sales to any accounts over which they
exercise discretionary authority without the prior written approval of the
customer.

  We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to 1,730,769 additional shares of
our Class A common stock at the public offering price less the underwriting
discount. The underwriters may exercise this option solely for the purpose of
covering over-allotments, if any, in connection with the offering. To the
extent this option is exercised, each underwriter will be obligated, subject to
various conditions, to purchase a number of additional shares approximately
proportionate to its initial purchase commitment.

  We, our executive officers and directors and, with certain limited
exceptions, all of our other existing shareholders have agreed not to do any of
the following, whether any transaction described in clause (1), (2) or (3)
below is to be settled by delivery of Class A common stock or other securities,
in cash or otherwise, in each case without the prior written consent of Lehman
Brothers Inc., on behalf of the underwriters, for a period of 180 days after
the date of this prospectus:

(1) offer, sell, pledge, or otherwise dispose of, or enter into any transaction
    or device which is designed or could be expected to, result in the
    disposition by any person at any time in the future of, any shares of Class
    A common stock or securities convertible into or exchangeable for Class A
    common stock or substantially similar securities, other than any of the
    following:

  .the Class A common stock sold under this prospectus and

  .  shares of Class A common stock we issue pursuant to employee benefit
     plans, qualified stock option plans or other employee compensation plans
     existing on the date of this prospectus or pursuant to currently
     outstanding options, warrants or rights;

(2) sell or grant options, rights or warrants with respect to any shares of our
    Class A common stock or securities convertible into or exchangeable for our
    Class A common stock or substantially similar securities, other than the
    grant of options pursuant to option plans existing on the date hereof; and

(3) enter into any swap or other derivatives transaction that transfers to
    another, in whole or in part, any of the economic benefits or risks or
    ownership of shares of Class A common stock.

  These lock up arrangements will be subject to the following exceptions:

  .transfers of common stock in private transactions or

  .transfers of common stock for estate planning purposes;

in each case, provided that the transferees agree to be bound by the
restrictions described above.


  Prior to the offering, there has been no public market for the shares of
Class A common stock. The initial public offering price will be negotiated
between the representatives and us. In determining the initial public offering
price of the Class A common stock, the representatives will consider, among
other things and in addition to prevailing market conditions, our historical
performance and capital structure, estimates of our business potential and
earnings prospects, an overall assessment of our management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.

  We have applied to list our Class A common stock on the Nasdaq National
Market under the symbol "SBAC".

  Any offer of the shares of Class A common stock in Canada will be made only
pursuant to an exemption from the prospectus filing requirement and an
exemption from the dealer registration requirement (where such an exemption is
not available, offers shall be made only by a registered dealer) in the
relevant Canadian jurisdiction where any such offer is made.

  In connection with the offering, Lehman Brothers, on behalf of the
underwriters, may purchase and sell shares of our Class A common stock in the
open market. These transaction may include over-allotment, syndicate covering
transactions and stabilizing transactions. Over-allotment involves syndicate
sales of Class A common stock in excess of the number of shares to be purchased
by the underwriters in the offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of our Class A common stock
in the open market after the distribution has been completed in order to cover
syndicate short positions. Stabilizing transactions consist of certain bids or
purchases of our Class A common stock made for the purpose of preventing or
retarding a decline in the market price of our Class A common stock while the
offering is in progress.

                                       77
<PAGE>

  The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Lehman Brothers, in covering syndicate short positions or making stabilizing
purchases, repurchases shares originally sold by that syndicate member.

  Any of these activities may cause the price of our Class A common stock to be
higher than the price that otherwise would exist in the open market in the
absence of such transactions. These transactions may be affected in the over-
the-counter market or otherwise and, if commenced, may be discontinued at any
time.

  Purchasers of the shares of Class A common stock offered in this prospectus
may be required to pay stamp taxes and other charges in accordances with the
laws and practices of the country of purchase, in addition to the offering
price set forth on the cover of this prospectus.

  We have agreed to indemnify the underwriters against liabilities, including
liabilities under the Securities Act of 1933, or to contribute to payments the
underwriters may be required to make in respect of any of those liabilities.

  Certain of the representatives have from time to time provided investment
banking, financial advisory and other services to us for which such
representatives received customary fees and commissions. Lehman Brothers acted
as co-arranger of our senior credit facility and its affiliate, Lehman
Commercial Paper Inc., is the administrative agent of the senior credit
facility. Lehman Commercial Paper Inc. will receive a portion of the proceeds
of the offering in repayment of indebtedness outstanding under the senior
credit facility. Lehman Brothers and BT Alex. Brown were also the initial
purchasers of our senior discount notes. In addition, BT Alex. Brown acted as
placement agent in connection with the private placement of shares of our
Series A preferred stock in March 1997. We granted BT Alex. Brown (which is now
referred to as "Deutsche Bank Securities") a warrant to purchase up to 402,500
shares of Class A common stock, subject to certain anti-dilution rights. An
affiliate of BT Alex. Brown is also a limited partner in ABS Capital Partners,
II, L.P. ABS Capital Partners, II, L.P. owns shares of our Series A preferred
stock. Certain officers and employees of BT Alex. Brown are direct and indirect
holders of Series A preferred stock. See "Principal Shareholders." Under Rule
2720 of the Conduct Rules of the NASD, BT Alex. Brown may be deemed to have a
"conflict of interest" with us. The offering is being conducted in accordance
with Rule 2720, which provides that, among other things, when a NASD member
participates in the underwriting of the equity securities of a company with
which it has a deemed "conflict of interest," the public offering price per
share can be no higher than that recommended by a "qualified independent
underwriter," or QIU, meeting certain standards. In accordance with this
requirement, Lehman Brothers has assumed the responsibilities of acting as QIU.
In its role as QIU, Lehman Brothers has performed a due diligence investigation
and reviewed and participated in the preparation of this prospectus and the
registration statement of which this prospectus in a part. We and the other
underwriters have agreed to indemnify Lehman Brothers in its capacity as QIU
against certain liabilities, including liabilities under the Securities Act, or
to contribute to payments Lehman Brothers in its capacity as QIU may be
required to make in respect of any of those liabilities.

Class A common stock will be passed upon for the underwriters by Simpson

              CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. General

  The accompanying unaudited condensed consolidated financial statements
include the accounts of SBA Communications Corporation and its subsidiaries
(the "Company"). All significant intercompany accounts and transactions have
been eliminated. Certain information related to the Company's organization,
significant accounting policies and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles has been condensed or omitted. These unaudited condensed
consolidated financial statements reflect, in the opinion of management, all
material adjustments (which included only normal recurring adjustments)
necessary to fairly state the financial position and the results of operations
for the periods presented and the disclosures herein are adequate to make the
information presented not misleading. Operating results for interim periods are
not necessarily indicative of the results that can be expected for a full year.
These interim financial statements should be read in conjunction with the
Company's audited consolidated financial statements and notes thereto.

  Certain reclassifications have been made to the 1998 financial statements to
conform to the 1999 presentation.

2. Current Accounting Pronouncements

Comprehensive Income

  In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income", which establishes standards for
reporting and display of comprehensive income and its components in a full set
of general-purpose financial statements. This statement requires that an
enterprise classify items of other comprehensive income separately from
accumulated deficit and additional paid-in-capital in the equity section of the
balance sheet. Comprehensive income is defined as the change in equity during
the financial reporting period of a business enterprise resulting from non-
owner sources. During the three months ended March 31, 1998 and 1999, the
Company did not have any changes in its equity resulting from such non-owner
sources and accordingly, comprehensive income as set forth by SFAS No. 130 was
equal to the net loss amounts presented for the respective periods in the
accompanying Consolidated Statements of Operations.

Derivative Instruments and Hedging Activities

  In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. SFAS
No. 133 requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. SFAS
No. 133 is effective for fiscal years beginning after June 15, 1999. Management
believes adopting this statement will not have a material impact upon the
Company's results of operations or financial position.

3. Acquisitions

  During the three months ended March 31, 1999, the Company completed five
acquisitions consisting of 38 towers and related assets from various sellers,
all of which were individually insignificant to the Company. The aggregate
purchase price was approximately $19,100,000 and was paid with proceeds from
long-term borrowings.

  The Company accounted for the above acquisitions using the purchase method of
accounting. The results of operations of the acquired assets are included with
those of the Company from the dates of the respective

acquisitions. The following unaudited pro forma summary for the three months
ended March 31, 1998 and 1999 presents the consolidated results of operations
as if the acquisitions had occurred as of the beginning of each of the periods
presented, after giving effect to certain adjustments such as depreciation.
These unaudited pro forma results have been prepared for comparative purposes
only and do not purport to be indicative of what would have occurred had the
acquisitions been made as of the beginning of the periods presented or of
results which may occur in the future.

Senior Credit Facility

  On February 5, 1999 the Company, through its subsidiary, SBA
Telecommunications Inc., ("Telecommunications") entered into a new senior
credit facility with a syndicate of lenders which replaced and superseded in
its entirety its previous credit agreement. The senior credit facility consists
of a $25 million term loan, which was fully funded at closing, and a $100
million revolving line of credit, on which the Company had the option to
increase to $150 million under certain conditions. Proceeds from the term loan
were used to repay the previous bank credit agreement. The senior credit
facility also provides for letter of credit availability. Availability under
the senior credit facility is determined by a number of factors, including
number of towers built by the Company with anchor tenants on the date of
completion, the financial performance of the Company's towers, site development
and construction segments, as well as by other financial covenants, financial
ratios and other conditions. The senior credit facility matures December 31,
2004 and amortization pursuant to a schedule and reduced availability begins
March 31, 2001. Borrowings under the senior credit facility bear interest at
the eurodollar rate plus a margin ranging from 2.25% to 3.50% (determined by a
leverage ratio) or "base rate" (as defined in the senior credit facility) plus
a margin ranging from 1.25% to 2.50% (determined by a leverage rate). The
senior credit facility is secured by substantially all of the assets of
Telecommunications and its direct and indirect subsidiaries, requires
Telecommunications to maintain certain financial ratios, and places
restrictions on, among other things, the incurrence of debt and liens,
dispositions of assets, transactions with affiliates and certain investments.
In connection with the termination of the previous credit agreement, the
Company recorded an extraordinary charge of approximately $1,150,000
representing the write-off of previously capitalized deferred financing fees
related to the previous bank credit agreement. Deferred financing fees related
to obtaining the new senior credit facility were approximately $3.9 million.
Additionally, on March 8, 1999, after receiving the requisite consents from the
holders of our senior discount notes, we amended the indenture governing the
notes to increase one of the categories of permitted indebtedness from $125.0
million to $175.0 million. In connection therewith, we paid $2.1 million to the
holders of the notes. The amount is also reflected in deferred financing fees.
Simultaneously, Telecommunications exercised its option to increase the
revolving line of credit portion of the senior credit facility from $100
million to $150 million.

  The Company has recorded a benefit in the first quarter of 1999 as a result
of net operating loss carrybacks available. The amount recorded as a benefit
represents the entire carryback amount available If the Company generates
taxable losses in the future, net operating loss carryforwards will be

8. Commitments and Contingencies

The Company is involved in various claims, lawsuits and proceedings arising in
the ordinary course of business. While there are uncertainties inherent in the
ultimate outcome of such matters and it is impossible to presently determine
the ultimate costs that may be incurred, management believes the resolution of
such uncertainties and the incurrence of such costs should not have a material
adverse effect on the Company's consolidated financial position or results of
operations.

10. Subsequent Events

  In April 1999, the Company adopted the 1999 Equity Participation Plan. A
total of 2,500,000 shares of Class A common stock are reserved for issuance
under this plan. In April, 1999, the Company granted options to employees for
the purchase of approximately an aggregate of 900,000 shares of Class A common
stock at an exercise price of $8.00 per share. The options will vest in three
installments commencing December 31, 1999 and ending April 19, 2002. Since the
exercise price range of these options is substantially below the midpoint of
the anticipated price range in the proposed initial public offering of Class A
common stock, the Company will record a non-cash compensation charge over the
vesting period of approximately $3.3 million.

  On April 19, 1999, the Company filed a Registration Statement on Form S-1 to
register shares of its Class A common stock in an initial public offering. The
Company filed for an offering of gross proceeds of $150.0

million, which is anticipated to produce net proceeds after deduction of the
underwriting discount and estimated offering expenses of $138.5 million. The
Company expects to use approximately $32.7 million of these net proceeds to pay
all outstanding dividends on all outstanding shares of the Company's Series A
preferred stock and to redeem all outstanding shares of the Company's Series B
preferred stock. The Company also expects to use $50.0 million to repay all
revolving credit loans under the senior credit facility. Remaining proceeds
will be used for the construction and acquisition of towers, the acquisition of
tower companies or related businesses, and for general working capital
purposes. There can be no assurance that the Company's planned initial public
offering of Class A common stock will be successfully consummated or, if
consummated, of the final terms of such initial public offering.

  On April 30, 1999, the Company acquired through merger all of the issued and
outstanding stock of Com-Net Construction Services, Inc. ("Com-Net"). The
Company issued 780,000 shares of its Class A common stock to the shareholders
of Com-Net, of which 480,000 shares have been pledged back to the Company and
are subject to forfeiture if certain 1999 earnings targets are not achieved by
the acquired company. The Company also assumed working capital debt of
approximately $4.5 million. In addition, the shareholders of Com-Net may
receive up to $2.5 million in cash and 320,000 additional shares of Class A
common stock if certain 1999 earnings targets are met by the acquired company,
and up to an additional 400,000 shares of Class A common stock if certain 2000
earnings targets are met.

  On the same date the Company acquired all of the issued and outstanding
capital stock of an affiliate of Com-Net, Com-Net Development Group, LLC
("Development Group"). Development Group owns 15 completed towers located in
Texas, Ohio and Tennessee and over 30 additional tower sites in various stages
of development under build-to-suit programs. The Company paid $1.0 million in
cash and assumed debt of approximately $2.5 million for Development Group.

  The Company will account for each of the above acquisitions as a purchase.

               Report of Independent Certified Public Accountants

To SBA Communications Corporation and Subsidiaries:

  We have audited the accompanying consolidated balance sheets of SBA
Communications Corporation (a Florida corporation) and subsidiaries as of
December 31, 1998 and 1997, and the related consolidated statements of
operations, stockholders' deficit and cash flows for each of the three years in
the period ended December 31, 1998. 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 generally accepted auditing
standards. 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 financial position of SBA Communications Corporation
and subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. GENERAL

  SBA Communications Corporation (the "Company") was incorporated in the State
of Florida in March, 1997. The Company holds all of the outstanding capital
stock of SBA Telecommunications, Inc. ("Telecommunications").
Telecommunications holds all of the capital stock of SBA Towers, Inc.
("Towers"), SBA, Inc. ("SBA" ), SBA Leasing, Inc. ("Leasing"), and
Communication Site Services, Inc ("CSSI").

  Towers and its subsidiaries own and operate transmission towers in various
parts of the country. Space on these towers is leased primarily to wireless
communications carriers.

  SBA provides comprehensive turnkey services for the telecommunications
industry in the areas of site development services for wireless carriers. Site
development services provided by SBA includes site identification and
acquisition, contract and title administration, zoning and land use permitting,
construction management and microwave relocation.

  Leasing leases antenna tower sites from owners and then subleases such sites
to wireless telecommunications providers.

  CSSI is engaged in the erection and repair of, and construction associated
with, transmission towers, including hanging of antennae, cabling and
associated tower components.

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. Basis of Consolidation

  The consolidated financial statements include the accounts of the Company and
all of its subsidiaries. All significant intercompany transactions have been
eliminated in consolidation.

  Prior to the formation of the Company, SBA and Leasing were 100% owned by
their founder. The 1996 financial statements reflect the combining of these two
companies rather than a consolidation.

  Historical net income (loss) per share has not been presented because it
would not be meaningful.

 b. Use of Accounting Estimates

The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. The more significant estimates made by management include
the allowance for doubtful accounts receivable, the costs and revenues relating
to the Company's site development and construction contracts and the economic
useful lives of towers. Actual results could differ from those estimates.

 c. Cash and Cash Equivalents

  The Company classifies as cash and cash equivalents all interest-bearing
deposits or investments with original maturities of three months or less.

                SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 d. Property and Equipment

  Property and equipment are recorded at cost. Depreciation is provided using
the straight-line method over their estimated useful lives. Leasehold
improvements are amortized on a straight-line basis over the shorter of the
useful life of the improvement or the term of the lease. Maintenance and
repairs are expensed as incurred.

  Interest is capitalized in connection with the construction of towers. The
capitalized interest is recorded as part of the asset to which it relates and
is amortized over the asset's estimated useful life. As the Company
significantly expanded its construction activities in 1998, $1,160,869 of
interest cost was capitalized in 1998. No interest was capitalized in 1997 or
1996.

 e. Intangible Assets

  Intangible assets are comprised of costs paid in excess of the fair value of
assets acquired ("Goodwill") and amounts paid related to covenants not to
compete. Goodwill is being amortized over periods which range from 7-15 years.
The covenants not to compete are being amortized over the terms of the
contracts, which range from 7 to 10 years. Accumulated amortization totaled
approximately $340,000 at December 31, 1998.

 f. Impairment of Long-Lived Assets

  Statement of Financial Accounting Standards No. 121 ("SFAS 121") Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed of requires that long-lived assets, including certain identifiable
intangibles, and the goodwill related to those assets, be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of the asset in question may not be recoverable. Management has
reviewed the Company's long-lived assets and has determined that there are no
events requiring impairment loss recognition.

 g. Deferred Financing Fees

  Financing fees have been deferred and are being amortized using the straight-
line method over the length of indebtedness to which they relate. This method
approximates the effective interest rate method.

 h. Revenue Recognition

  Revenue from tower leasing services is recorded on a monthly basis. Revenue
for Leasing is generated on a monthly basis from subleases entered into for
periods of time equivalent to the Company's original lease obligation. Current
lease terms range from one to five years. Revenue received in advance is
recorded in other liabilities.

  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 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. Revenue related to services performed on
uncompleted phases of site development projects was not recorded by the Company
at the end of the reporting periods presented as it was not material to the
Company's results of operations. Any losses on a particular phase of completion
are recognized in the period in which the loss becomes evident. Site
development projects generally take from 3 to 12 months to complete.

<PAGE>

                SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  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 anticipated 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 revenues
recognized in excess of amounts billed. The liability, "Billings in excess of
costs and estimated earnings on complete contracts" represents billings in
excess of revenues recognized.

  Costs of site development project revenue and construction revenue include
all direct material costs, salaries and labor costs, including payroll taxes,
subcontract labor, vehicle expense and other costs directly related to the
projects. All costs related to site development projects and construction
projects are recognized as incurred. Provisions for estimated losses on
uncompleted contracts are made in the period in which such losses are
determined to be probable.

 i. Income Taxes

  Effective January 1, 1997, the Company converted to a C Corporation under
Subchapter C of the Internal Revenue Code of 1986, as amended. The pro-forma
provision for income taxes for the year ended December 31, 1996 represents a
pro-forma calculation (40%) as if the Company was a C Corporation.

  Effective January 1, 1997, the Company began accounting for income taxes in
accordance with the provisions of Statement of Financial Accounting Standards
No., 109 Accounting for Income Taxes ("SFAS No. 109"). SFAS No. 109 requires
the Company to recognize deferred tax liabilities and assets for the expected
future income tax consequences of events that have been recognized in the
Company's consolidated financial statements. Deferred tax liabilities and
assets are determined based on the temporary differences between the
consolidated financial statements carrying amounts and the tax bases of assets
and liabilities, using enacted tax rates in the years in which the temporary
differences are expected to reverse.

 j. Selling, General and Administrative Expenses

  Selling, general and administrative costs represents those costs incurred
which are related to the administration or management of the Company. Also
included in this category are corporate development expenses which represent
costs incurred in connection with acquisitions, construction activities and
expansion of the customer base. These expenses consist of compensation and
overhead costs that are not directly related to the administration or
management of existing towers. The above costs are expensed as incurred.

 k. Fair Value of Financial Instruments

  The carrying value of cash and cash equivalents, accounts receivable, prepaid
expenses, notes receivable, accounts payable, accrued expenses and notes
payable, approximates fair value. The market value and carrying value of the
Senior Discount Notes Payable is $156.0 million and $165.6 million at December
31, 1998, respectively.

 l. Reclassifications

  Certain reclassifications have been made to the 1997 and 1996 financial
statements to conform to the 1998 presentation.

3. CURRENT ACCOUNTING PRONOUNCEMENTS

 Comprehensive Income

  In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income" which establishes standards for
reporting and display of comprehensive income and its components in a full set
of general-purpose financial statements. This statement requires that an
enterprise classify items of other comprehensive income separately from
accumulated deficit and additional paid-in capital in the equity section of the
balance sheets. Comprehensive income is defined as the change in equity during
the financial reporting period of a business enterprise resulting from non-
owner sources. During the year ended December 31, 1998, 1997, and 1996, the
Company did not have any changes in its equity resulting from such non-owner
sources and accordingly, comprehensive income as set forth by SFAS No. 130 was
equal to the net loss amounts presented for the respective periods in the
accompanying Consolidated Statements of Operations.

 Segment Reporting

  In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" which is required to be adopted in fiscal
1998. SFAS No. 131 requires the Company to report financial and other
descriptive information about its reportable operating segments. Required
disclosures include, among other things, a measure of segment profit or loss,
certain specific revenue and expense items, and segment assets. The Company has
implemented SFAS No. 131 during 1998.

 Derivative Instruments and Hedging Activities

  In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities. "This statement establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. SFAS
No. 133 will require that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. SFAS
No. 133 is effective for fiscal years beginning after June 15, 1999. Management
believes the impact of adopting this statement will not have a material impact
upon the Company's results of operations or financial position.

4. ACQUISITIONS

  On September 18, 1997, the Company consummated the acquisition of CSSI and
certain related tower assets of Segars Communications Group, Inc. ("SCGI," and
together with the acquisition of CSSI, the "CSSI Acquisition"). The CSSI
Acquisition provided the Company with 21 towers in Florida and Georgia in
varying stages of construction, together with a number of parcels of leased
real estate on which towers may be constructed in the future, and gave the
Company the in-house capability to construct towers in the southeastern United
States. The Company paid $7 million at closing and an additional $2.6 million
as a contingent payment to the sellers, which was based on certain tenant
leasing goals being realized. The acquisition was accounted for under the
purchase method of accounting. Accordingly, the excess of the purchase price
over the estimated fair value of the net assets acquired, or approximately $2.1
million, was recorded as goodwill which is being amortized on a straight-line
basis over a period of 15 years. CSSI's results of operations have been
included in the Company's consolidated financial statements from the date of
acquisition. Additionally, in 1997, the Company acquired 30 towers in five
separate transactions for an aggregate initial investment of $5.9 million.
These acquisitions were paid for in cash.

  During 1998, the Company completed 39 acquisitions consisting of 135 towers
and related assets from various sellers, all of which were individually
insignificant to the Company. The aggregate purchase price for these
acquisitions for the year ended December 31, 1998 was $55.3 million, which was
paid from cash on hand.

<PAGE>

                SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  The Company accounted for the above acquisitions using the purchase method of
accounting. The results of operations of the acquired assets are included with
those of the Company from the dates of the respective acquisitions. The pro-
forma results of operations listed below reflect purchase accounting and pro-
forma adjustments as if the transactions occurred as of the beginning of the
period presented.

  The unaudited pro-forma results have been prepared for comparative purposes
only and include certain adjustments, such as additional amortization expense
as a result of goodwill and pro-forma provision for income taxes for the period
in which CSSI was an S Corporation under Subchapter S of the Internal Revenue
Code. The pro-forma results do not purport to be indicative of results that
would have occurred had the combination been in effect for the periods
presented, nor do they purport to be indicative of the results that will be
obtained in the future.

5. CONCENTRATION OF CREDIT RISK

  The Company's credit risks consist of accounts receivable in the
telecommunications industry. The Company performs periodic credit evaluations
of its customers' financial condition and provides allowances for doubtful
accounts as required. Following is a list of significant customers and the

 Bank Credit Agreement

  On August 8, 1997, the Company entered into a credit agreement with a
syndicate of banks (the "Credit Agreement"). The original Credit Agreement
consisted of a secured revolving line of credit in the amount of

                                      F-23
<PAGE>

                SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
$10,000,000 and term debt in an amount up to $65,000,000. Under this Agreement
funds were generally borrowed at the EURO rate at the time of borrowing plus
1.25%.

  On June 29, 1998, the Company amended and restated the Credit Agreement. The
amended Credit Agreement provides for revolving credit loans of $55,000,000.
Availability was limited based on a minimum number of owned, leased or managed
towers and at all times by certain financial conditions and covenants and
ratios, and other conditions. The Credit Agreement matures on June 29, 2005.
The borrowings under the Credit Agreement will bear interest at the EURO rate
plus a margin ranging from 1.0% to 3.25% (determined based on a leverage ratio)
or an "alternate base rate" as defined by the lender. The term facility
provided $50,000,000 availability to the Company to be used to secure letters
of credit. As of December 31, 1998, there were no outstanding letters of
credit.

  The Credit Agreement is secured by substantially all of the Company's tower
assets and assignment of tower leases, requires the Company to maintain certain
financial covenants and places restrictions on the Company's ability to, among
other things, incur debt and liens, dispose of assets, undertake transactions
with affiliates and make investments.

  This credit agreement was replaced by a new credit facility in February, 1999
(See Note 16).

 Senior Discount Notes Payable

  On March 2, 1998, the Company closed on $269,000,000 12% Senior Discount
Notes (the "Notes") due March 1, 2008. The issuance of the Notes netted
approximately $150,200,000 in proceeds to the Company. The Notes will accrete
in value until March 1, 2003 at which time they will have an aggregate
principal amount of $269,000,000. Thereafter, interest will accrue on the Notes
and will be payable semi-annually in arrears on March 1 and September 1,
commencing September 1, 2003. Proceeds from the Notes are being used to acquire
and construct telecommunications towers as well as for general working capital
purposes.

  After the issuance of the Notes, the Company became highly leveraged which
could have important consequences to holders of the Notes and common and
preferred stockholders of the Company, including, but not limited to: (i)
making it more difficult for the Company to satisfy its obligations with
respect to the Notes, (ii) increasing the Company's vulnerability to general
adverse economic and industry conditions, (iii) limiting the Company's ability
to obtain additional financing to fund its growth strategy, future working
capital, capital expenditures and other general corporate requirements, (iv)
requiring the dedication of a substantial portion of the Company's cash flow
from operations to the payment of principal of, and interest on, its
indebtedness, thereby reducing the availability of such cash flow to fund its
growth strategy, working capital, capital expenditures or other general
corporate purposes, (v) limiting the Company's flexibility in planning for, or
reacting to, changes in its business and the industry, and (vi) placing the
Company at a competitive disadvantage vis-a-vis less leveraged competitors. In
addition, the degree to which the Company is leveraged could prevent it from
repurchasing any Notes tendered to it upon the occurrence of a change of
control.

  There can be no assurance that the Company will generate sufficient cash flow
from operations in the future, that anticipated revenue growth will be realized
or that future borrowings or equity contributions will be available in amounts
sufficient to service its indebtedness and make anticipated capital
expenditures. In addition, there can be no assurance that the Company will be
able to effect any required refinancing of its indebtedness (including the
Notes) on commercially reasonable terms or at all.

  The Notes and Credit Agreement contain numerous restrictive covenants,
including but not limited to covenants that restrict the Company's ability to
incur indebtedness, pay dividends, create liens, sell assets and engage in
certain mergers and acquisitions. The ability of the Company to comply with the
covenants and other

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
terms of the Notes and to satisfy its respective debt obligations will depend
on the future operating performance of the Company. In the event the Company
fails to comply with the various covenants contained in the Notes it would be
in default thereunder, and in any such case, the maturity of substantially all
of its long-term indebtedness could be accelerated.

9. NOTE RECEIVABLE--STOCKHOLDER

  The amount due from stockholder as of December 31, 1998 and 1997, represents
a loan made to one of the stockholders plus accrued interest. The loan was in
the amount of $3.5 million and bears interest at a rate of 5.83%. This loan
matures at the earlier of three years or upon consummation of an initial public
offering of the Company. This loan is secured by 823,530 shares of Class B
Common Stock of the Company owned by the stockholder.

10. REDEEMABLE PREFERRED STOCK

  In 1997, the Company sold 8,050,000 shares of 4% Series A Preferred Stock,
convertible into one share of the Company's Class A Common Stock and one share
of the Company's 4% Series B Redeemable Preferred Stock, to a syndicate of
institutional investors (the "Private Investors"). The Series A Preferred Stock
has a conversion price of $3.73 and net proceeds received by the Company from
the sale of the shares was approximately $27,600,000 (net of approximately
$2,400,000 of issuance costs charged to retained earnings).

  The Series A Preferred Stock has the following rights and preferences:

  Each holder of Series A Preferred Stock has the right to convert his or her
shares at any time into one share of Class A Common Stock, subject to certain
antidilution protection provisions, and one share of Series B Preferred Stock.

  The Series A Preferred Stock will automatically convert into Class A Common
Stock and Series B Preferred Stock upon the earlier of (i) completion by the
Company of a public offering raising gross proceeds of at least $20,000,000 at
an offering price per share greater than or equal to 150% of then applicable
conversion price of the Series A Preferred Stock if such public offering occurs
before June 30, 1998 or at a price per share greater than or equal to 200% of
the then applicable conversion price of the Series A Preferred Stock if such
public offering occurs after June 30, 1998 or (ii) the written consent of the
holders of at least 66 2/3% of the Series A Preferred Stock then outstanding.

  The holders of outstanding shares of Series A Preferred Stock are entitled,
in preference to the holders of any and all other classes of capital stock of
the Company (other than the Series B Preferred Stock, which will rank equally
with the Series A Preferred Stock as to dividends), to receive, out of funds
legally available therefore, cumulative dividends on the Series A Preferred
Stock in cash, at a rate per annum of 4% of the Series A Base Liquidation
Amount subject to pro-ration for partial years. The Series Base Liquidation
Amount equals the sum of $3.73 and any accumulated and unpaid dividends on the
Series A Preferred Stock. Accrued but unpaid dividends on the Series A
Preferred Stock will be payable upon conversion of the Series A Preferred Stock
into Class A Common Stock and Series B Preferred Stock. At December 31, 1998,
such accrued and unpaid dividends amounted to $3,558,333. At March 7, 2002, the
dividend rate of the Series A Preferred Stock will increase to 8% of the Series
A Base Liquidation Amount per annum. On March 7, 2003, the dividend rate on the
Series A Preferred Stock will increase to 14% per year. On March 7, 2002, the
Company will, to the extent it may do so under applicable law, redeem all of
the outstanding shares of Series A Preferred Stock over a two year period, one
half in each year, at an aggregate price equal to the Series A Base Liquidation
Amount. The Company accretes for preferred stock dividends on the effective
interest rate method over the period from issuance to scheduled redemption.

                SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  In the event of any liquidation or winding up of the Company, including a
merger, sale of all of its outstanding shares of capital stock, consolidation
or sale of all or substantially all of the assets of the Company, each holder
of outstanding Shares of Series B Preferred Stock will be entitled to receive
before any amount shall be paid or distributed to the holders of the Common
Stock, an amount in cash equal to the sum of $3.73 per share plus any
accumulated but unpaid dividends to which such holder is entitled.

  The holders of Series A Preferred Stock have ten votes for each share until
converted to Class A Common Stock and Series B Preferred Stock and votes with
holders of shares of Class A Common Stock and Class B Common Stock as a single
voting group on all matters brought before the shareholders, except as
otherwise required by law and other restrictive covenants. The Series B
Preferred Stock does not have voting rights.

  The holders of the shares of Series A Preferred Stock are entitled to
participate on a pro rata basis in certain issuances of equity securities by
the Company.

  The Series B Preferred Stock generally has the same rights and preferences as
the Series A Preferred Stock plus the following rights and preferences:

  Upon a qualified public offering, the Company will redeem all of the
outstanding shares of Series B Preferred Stock at an aggregate price equal to
the Series B Base Liquidation Amount.

  The Company's Articles of Incorporation also provide for the issuance of
Series C Preferred Stock and Series D Preferred Stock. The terms of the Series
C Preferred Stock are substantially similar to the terms of the Series A
Preferred Stock other than the Series C Base Liquidation Amount, which is
currently $4.472 per share. The terms of the Series D Preferred Stock is
substantially similar to the terms of the Series B Preferred Stock other than
the Series D Liquidation Amount, which is $4.472. Management at this time does
not expect to issue any shares of Series C Preferred Stock or Series D
Preferred Stock.

  In connection with the acquisition of certain towers during 1998, the Company
recorded deferred tax liabilities and goodwill of $4.2 million related to the
book/tax basis differences in the acquired towers.

  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.

Officer, the Chief Accounting Officer, the Chief Financial Officer, and the
Executive Vice President--Sales and Marketing. These employment contracts are
for a three year period and provide for minimum annual compensation of
$1,025,000. Additionally, these contracts provide for incentive bonuses of
annual amounts up to $1,025,000.

 d. Litigation

  The Company is involved in various claims, lawsuits and proceedings arising
in the ordinary course of business. While there are uncertainties inherent in
the ultimate outcome of such matters and it is impossible to

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
presently determine the ultimate costs that may be incurred, management
believes the resolution of such uncertainties and the incurrence of such costs
should not have a material adverse effect on the Company's consolidated
financial position or results of operations.

13. HEALTH AND RETIREMENT PLANS

  The Company has a defined contribution profit sharing plan under Section 401
(k) of the Internal Revenue Code that provides for voluntary employee
contributions of 1% to 14% of compensation for substantially all employees. The
Company makes a matching contribution of 50% of an employee's first $2,000 of
contributions. Company contributions and other expenses associated with the
plan were $123,981, $126,101, and $98,052 for the years ended December 31,
1998, 1997, and 1996 respectively.

14. STOCK OPTIONS AND WARRANTS

  As of December 31, 1996, certain of the Company's senior executives
terminated existing employment, incentive and option agreements in exchange for
new employment agreements and, immediately exercisable options to purchase
1,425,000 shares of Class A Common Stock. All of the options are exercisable at
$.05 per share. The Company accounted for the grant of options in accordance
with APB No. 25 and, accordingly, recognized a nonrecurring compensation
expense of $7,011,000 in 1996 as a result of the grant of the options. The
expense represents the difference between the exercise price of the options and
the estimated fair value of the underlying common stock. During March 1997,
immediately following the consummation of the Series A Preferred Stock
offering, options to purchase 264,708 shares of Class A Common Stock were
redeemed by the Company for $8.50 per share. Accordingly, the Company
recognized compensation expense totaling $934,419 which represented the
difference between the redemption value and the fair value of the common stock
at the date of grant.

  The Company also has a stock option plan whereby options (both Non-qualified
and Incentive Stock Options), stock appreciation rights and restricted stock
may be granted to directors, key employees and consultants. A total of
1,800,000 shares of Class A Common Stock are reserved for issuance under this
plan. These options generally vest over three-year periods from the date of
grant. The Company accounts for this plan under APB Opinion No. 25, under which
compensation cost is not recognized on those issuances where the exercise price
exceeds the market price of the underlying stock on the grant date.

  In connection with the issuance of the redeemable preferred stock the Company
issued a five year warrant enabling the holder to purchase up to 402,500 shares
of Class A Common stock with an exercise price of $3.73 per share. Accordingly,
402,500 shares of Class A Common stock are reserved. The fair value of the
warrants at issuance was not material.

  During 1998, 208,419 options to purchase Class A Common Stock were issued at
exercise prices which the Company believed were at below market value.
Accordingly, the Company recorded compensation expense in the amount of
$174,810. Additional compensation related to these options of approximately
$278,518 will be recorded by the Company over the remaining vesting period of
the options. Also during 1998, the Company granted 104,961 shares of Class A
Common Stock to two executives and recorded non-cash compensation expense of
$505,167 which represents the fair value of the shares on the date of grant.

  As required by FASB Statement No. 123 ("FASB 123"), for those options which
the Company granted at or above fair market value, the Company has determined
the pro-forma effect of the options granted had the Company accounted for stock
options granted under the fair value method of FASB 123. The Black-Scholes
option pricing model was used with the following assumptions for 1998 and 1997;
risk free interest rate of

12%, dividend yield of 0%; expected volatility of .001% and expected lives of 3
years. Had compensation cost for the stock option plan been determined based on
fair value at the date of grant in accordance with FASB 123, the Company's pro-
forma net income (loss) would have totaled $(20,156,126) and $162,111 for the
years ended December 31, 1998 and 1997, respectively. The effect of applying
FASB 123 in this pro-forma disclosure are not necessarily indicative of future
results.

16. SUBSEQUENT EVENTS

  On February 5, 1999 the Company, through its subsidiary, Telecommunications,
entered into a new senior credit facility (the "New Facility") with a syndicate
of lenders which replaced and superceded in its entirety the Credit Agreement
described in Note 8. The New Facility consists of a $25 million term, loan,
which was fully funded at closing, and a $100 million revolving line of credit,
on which the Company has the option to increase to $150 million under certain
conditions. The New Facility also provides for letter of credit availability.
Availability under the New Facility is determined by a number of factors,
including number of towers built by the Company with anchor tenants on the date
of completion, the financial performance of the Company's towers, site
development and construction segments, as well as by other financial covenants,
financial ratios and other conditions. The New Facility matures December 31,
2004 and amortization pursuant

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
to a schedule and reduced availability begins March 31, 2001. Borrowings under
the New Facility will bear interest at the EURO rate plus a margin ranging from
2.25% to 3.50% (determined by a leverage ratio) or "base rate" (as defined in
the New Facility) plus a margin ranging from 1.25% to 2.50% (determined by a
leverage rate). The New Facility is secured by substantially all of the assets
of Telecommunications and its direct and indirect subsidiaries, requires
Telecommunications to maintain certain financial covenants, and places
restrictions on, among other things, the incurrence of debt and liens,
dispositions of assets, transactions with affiliates and certain investments.
In connection with the termination of the previous Credit Agreement during the
first quarter of 1999, the Company recorded an extraordinary charge of
approximately $950,000 representing the write-off of previously capitalized
deferred financing fees related to the previous Credit Agreement . On March 8,
1999, after receiving the requisite consents from the holders of the Notes, the
Company amended the indenture governing the Notes to increase one of the
categories of permitted indebtedness from $125 million to $175 million.
Simultaneously, Telecommunications exercised its option to increase the
revolving line of credit portion of the New Facility from $100 million to $150
million.

               Report of Independent Certified Public Accountants

To SBA Communications Corporation:

  We have audited the accompanying statements of operations and retained
earnings and cash flows of Caddo Tower Company, Inc. (a Florida corporation)
for the fiscal year ended July 31, 1998. 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 audit.

  We conducted our audit in accordance with generally accepted auditing
standards. 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 results of operations and cash flows of Caddo Tower
Company, Inc., for the fiscal year ended July 31, 1998, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                        For the Year Ended July 31, 1998

1. Nature of Business and Basis of Presentation

 Nature of Business

  On October 8, 1998, SBA Towers, Inc. ("SBA") acquired all of the outstanding
stock of Caddo Tower Company, Inc. ("Caddo" or "the Company")--see Note 5.
Caddo owns telecommunications towers and leases space on these towers to
customers in the wireless communications industries in Louisiana. The Company
also has operations in the commercial real estate business in Shreveport,
Louisiana.

 Basis of Presentation

  The accompanying statements of operations and retained earnings, and cash
flows of Caddo have been prepared in accordance with generally accepted
accounting principles. Certain of the Company's activities have been treated as
discontinued operations and are presented as such in the accompanying statement
of operations and retained earnings. See Note 4.

2. Summary of Significant Accounting Policies

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from these estimates.

 Property and Equipment

  Caddo owns fixed assets used in the tower and commercial real estate
businesses. All assets are recorded at cost. Tower assets consist of towers,
portable buildings and related attachments which are depreciated using the
straight-line method over the estimated useful life of the assets of 15 years.
Improvements, renewals and extraordinary repairs which increase the value or
extend the life of the asset are capitalized. Repairs and maintenance costs are
expensed as incurred.

 Impairment of Long-lived Assets

  The Company evaluates the recoverability of its long-lived assets whenever
the adverse events or changes in business climate indicate that the expected
undiscounted cash flows from the related asset may be less than previously
anticipated. If the net book value of the related asset exceeds the
undiscounted future cash flows of the asset, the carrying amount would be
reduced to the present value of its expected future cash flows and an
impairment loss would be recognized. As of July 31, 1998, the Company does not
believe that an impairment is necessary.

 Revenue Recognition

  Rental revenue is recognized on a straight-line basis over the life of the
related lease agreements. Revenue is recorded in the month in which it is due.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                        For the Year Ended July 31, 1998

 Income Taxes

  The Company accounts for income taxes using the liability method as required
by Statement on Financial Accounting Standards ("SFAS") No. 109, "Accounting
for Income Taxes." The significant difference between the tax bases of assets
and liabilities and the bases used for financial accounting and reporting is
due to differences in the methods used to compute depreciation expense.

  The effective tax rate approximates the statutory federal and state rates on
a historical basis as only immaterial permanent differences exist for the
Company.

3. Tenant Leases and Commitments

  The following is a schedule of total future minimum rentals to be received
from tower space under non-cancelable lease agreements as of July 31, 1998:

                                                                        ========
</TABLE>

  In addition, the Company made payments of approximately $38,000 during the
current fiscal year under lease commitments.

4. Discontinued Operations

  Subsequent to July 31, 1998, but prior to October 8, 1998, the Company
transferred all of its assets and liabilities related to the commercial real
estate business to a newly created company that was not sold to SBA. The newly-
created company is owned by the same owners of Caddo Tower Company, Inc.

  The results of the non-tower operations for the fiscal year ended July 31,
1998, have thus been treated as discontinued operations in the accompanying
statement of operations and retained earnings for the fiscal year ended July
31, 1998. Revenues and expenses of the discontinued operations for the fiscal
year ended July 31, 1998, were $72,850 and $77,705, respectively.

5. Subsequent Event

  On October 8, 1998, SBA acquired all of the outstanding common stock of the
Company for approximately $4,925,000. In anticipation of this sale but
subsequent to July 31, 1998, the Company transferred all of its non-tower
assets and liabilities to another company created to receive these non-tower
assets and liabilities. See Note 4.

               Report of Independent Certified Public Accountants

To SBA Communications Corporation:

  We have audited the accompanying statements of operations and retained
earnings and cash flows of the tower assets acquired from PrimeCo Personal
Communications L.P. (see Note 1) for the year ended December 31, 1997. 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 audit.

  We conducted our audit in accordance with generally accepted auditing
standards. 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 results of operations and cash flows of the tower
assets acquired from PrimeCo Personal Communications L.P., for the year ended
December 31, 1997 in conformity with generally accepted accounting principles.

         (A carve-out entity of PrimeCo Personal Communications, L.P.)

                         NOTES TO FINANCIAL STATEMENTS

1. Natures of Business and Basis of Presentation

 Nature of Business

  On April 15, 1998 SBA Towers, Inc. acquired certain of the assets and
business operations of PrimeCo Personal Communications, L.P. (the "Parent").
See Note 5. Collectively, the acquired assets and related operations are
referred to hereafter as PrimeCo-Wisconsin. PrimeCo-Wisconsin owns
telecommunications towers and leases space on these towers to customers in the
wireless communications industries in Wisconsin.

 Basis of Presentation

  PrimeCo-Wisconsin is not a separate subsidiary, division or segment of the
Parent. The accompanying statement of operations and cash flows have been
derived from the accounting records of the Parent and have been prepared to
present the result of operations and cash flows on a stand-alone basis. All
revenues and expenses specifically identifiable to tower ownership are
included.

  PrimeCo-Wisconsin began construction on the eight towers, subsequently sold
to SBA Towers, Inc. (see Note 5), in the latter half of 1997. As of December
31, 1997, construction on all eight towers was still in progress. As such, no
revenue had been earned, nor did the Parent record any depreciation expense or
allocate any general and administrative expenses to these towers.

  All costs incurred and presented in the accompanying financial statements
represent direct costs incurred by the tower operations. It is the Parent's
policy not to allocate overhead or other costs to towers until construction is
complete and the towers have been placed into service.

2. Summary of Significant Accounting Policies

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and use assumptions
that affect the reported amounts of assets and liabilities and the disclosure
for contingent assets and liabilities at the date of the financial statements
as well as the reported amounts of revenues and expenses during the reporting
period. Actual results may vary from those estimates.

 Tower Assets

  Tower assets consist of towers, buildings, and related attachments which are
recorded at cost and will be depreciated using the straight-line method over
the estimated useful life of the assets of 15 years. Depreciation of the asset
begins at the time the asset is placed in service. Improvements, renewals and
extraordinary repairs which increase the value or extend the life of the asset
are capitalized. Repairs and maintenance costs are expensed as incurred.

 Impairment of Long-lived Assets

  PrimeCo-Wisconsin evaluates the recoverability of its long-lived assets
whenever adverse events or changes in business climate indicate that the
expected undiscounted future cash flows from the related asset may be less than
previously anticipated. If the net book value of the related asset exceeds the
undiscounted future cash flows of the asset, the carrying amount would be
reduced to the present value of its expected future cash flows and an
impairment loss would be recognized. As of December 31, 1997, management does
not believe that an impairment reserve is required.

                                      F-43
<PAGE>

 Revenue Recognition

  Rental revenue is recognized on a straight-line basis over the life of the
related lease agreements. Revenue is recorded in the month in which it is due.

 Income Taxes

  PrimeCo-Wisconsin generated a net loss for the year ended December 31, 1997.
Accordingly, no benefit has been recorded in the statement of operations and
retained earnings.

3. Commitments and Contingencies

  The Company is obligated under eight non-cancelable leases for land which
expire between July 23, 2001 and June 16, 2003. The future minimum lease
commitments under these leases are as follows:

                                                                        ========
</TABLE>

  Rental expense for 1997 was $20,157.

4. Related party Transactions

  The Parent paid all costs related to the site development and construction of
these eight towers. In addition, the Parent also paid all tower operating
expenses related to PrimeCo-Wisconsin. For the year ended December 31, 1997,
PrimeCo-Wisconsin incurred tower operating expenses of $20,157, which were
directly attributable to PrimeCo-Wisconsin.

5. Subsequent Event

  On April 15, 1998, eight towers and related assets were sold to SBA Towers,
Inc. In accordance with the purchase and sale agreement, PrimeCo Personal
Communications, L.P. received approximately $1,353,325 for these eight towers
and related assets.

                         NOTES TO FINANCIAL STATEMENTS

1. Natures of Business and Basis of Presentation

  Nature of Business

  On June 29, 1998, SBA Towers, Inc. acquired the assets and business
operations of Northwest Tower Service, Inc., a Minnesota Corporation (the
"Company"). The Company owns telecommunications towers and leases space on
these towers to customers in the wireless communications industries in Virginia
and Minnesota.

  Basis of Presentation

  The accompanying financial statements have been prepared in accordance with
generally accepted accounting principles.

2. Summary of Significant Accounting Policies

  Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and use assumptions
that affect the reported amounts of assets and liabilities and the disclosure
for contingent assets and liabilities at the date of the financial statements
as well as the reported amounts of revenues and expenses during the reporting
period. Actual results may vary from those estimates.

  Tower Assets

  Tower assets consist of towers, buildings, and related attachments which are
recorded at cost and depreciated using the straight-line method over the
estimated useful life of the assets of 15 years. Improvements, renewals and
extraordinary repairs which increase the value or extend the life of the asset
are capitalized. Repairs and maintenance costs are expensed as incurred.

  Impairment of Long-lived Assets

  The Company evaluates the recoverability of its long-lived assets whenever
adverse events or changes in business climate indicate that the expected
undiscounted future cash flows from the related asset may be less than
previously anticipated. If the net book value of the related asset exceeds the
undiscounted future cash flows of the asset, the carrying amount would be
reduced to the present value of its expected future cash flows and an
impairment loss would be recognized. As of December 31, 1997, management does
not believe that an impairment reserve is required.

  Revenue Recognition

  Rental revenue is recognized on a straight-line basis over the life of the
related lease agreements. Revenue is recorded in the month in which it is due.

  Income Taxes

  The Company consisted of certain assets of an S Corporation. The statement of
operations and retained earnings reflects a tax provision for the operations of
Northwest Tower Service, Inc. at December 31, 1997 on a pro-forma basis as if
the Company were treated as a C Corporation.

4. Subsequent Events

  On June 29, 1998, the Company sold significantly all of its assets to SBA

Tower Service, Inc., received approximately $4,900,000 for three towers,
related assets and land.

               Report of Independent Certified Public Accountants

To SBA Communications Corporation:

  We have audited the accompanying statements of operations and retained
earnings and cash flows of the tower assets acquired from General
Communications Properties, Inc. (see Note 1) for the year ended December 31,
1997. 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 audit.

  We conducted our audit in accordance with generally accepted auditing
standards. 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 results of operations and cash flows of the tower

ended December 31, 1997 in conformity with generally accepted accounting

                         NOTES TO FINANCIAL STATEMENTS

1. Natures of Business and Basis of Presentation

 Nature of Business

  On August 31, 1998, SBA Towers, Inc. acquired certain of the assets and
business operations of General Communications, Properties, Inc., a Kansas
corporation (the "Parent"). Collectively, the acquired assets and related
operations are referred to hereafter as General Communications. General
Communications owns one telecommunications tower and leases space on this tower
to customers in the wireless communications industries in Kansas.

 Basis of Presentation

  General Communications is not a separate subsidiary, division or segment of
the Parent. The accompanying statements of operations and retained earnings and
cash flows of General Communications have been derived from the accounting
records of General Communications, Inc., and have been prepared to present the
results of operations and cash flows on a stand-alone basis. All revenues and
expenses specifically identifiable to tower ownership are included.
Additionally, the accompanying statement of operations and cash flows include
certain costs and expenses that have been allocated to the tower business from
the Parent. These costs have been allocated on a carve-out basis described in
Note 2.

2. Summary of Significant Accounting Policies

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and use assumptions
that affect the reported amounts of assets and liabilities and the disclosure
for contingent assets and liabilities at the date of the financial statements
as well as the reported amounts of revenues and expenses during the reporting
period. Actual results may vary from those estimates.

 Tower Assets

  Tower assets consist of a tower, buildings, and related attachments which are
recorded at cost and depreciated using the straight-line method over the
estimated useful life of the assets of 15 years. Improvements, renewals and
extraordinary repairs which increase the value or extend the life of the asset
are capitalized. Repairs and maintenance costs are expensed as incurred.

 Impairment of Long-lived Assets

  General Communications evaluates the recoverability of its long-lived assets
whenever adverse events or changes in business climate indicate that the
expected undiscounted future cash flows from the related asset may be less than
previously anticipated. If the net book value of the related asset exceeds the
undiscounted future cash flows of the asset, the carrying amount would be
reduced to the present value of its expected future cash flows and an
impairment loss would be recognized. As of December 31, 1998, management does
not believe that an impairment reserve is required.

 Revenue Recognition

  Rental revenue is recognized on a straight-line basis over the life of the
related lease agreements. Revenue is recorded in the month in which it is due.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

 Allocation of Expenses

  The accompanying financial statements include certain costs and expenses that
have been allocated to the tower business from the Parent. Of approximately
$130,000 in expenses incurred by General Communications Properties, Inc., on
behalf of all of its businesses, $26,166 has been allocated to the tower
operations on a pro rata basis primarily on revenues. Management believes this
allocation is reasonable.

 Income Taxes

  General Communications consisted of certain assets of an S Corporation. As
such, net income was not subject to income taxes as the income is taxed
directly to their owners. The statement of operations and retained earnings
reflects a tax provision for the operations of General Communications at
December 31, 1997 on a pro forma basis as if General Communications were
treated as a C corporation.

</TABLE>

4. Subsequent Events

  On August 31, 1998 a tower and related assets were sold to SBA Towers, Inc.
In accordance with the purchase and sale agreement, the owners of General
Communications received approximately $1,400,000 for the tower, related assets
and land.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1--Summary of Significant Accounting Policies

 Nature of Business

  Transmission Facilities, Inc. (the "Company") is in the business of operating
facilities for the transmission of television, radio and other communication by
wire or airwave.

 Depreciation

  Property and equipment are stated at cost. Maintenance and repairs are
charged to expense as incurred; costs of major additions and betterments are
capitalized. The Company provides for depreciation over the estimated useful
life of the asset based upon accelerated methods. Leasehold improvements are
amortized using the straight-line method over the estimated useful life of the
related improvements.

 Income Taxes

  The Company, with the consent of its stockholders, has elected under the
Internal Revenue Code to be an "S" corporation. This election provides that, in
lieu of federal corporate income taxes, the stockholders are taxed on their
proportionate share of the Company's taxable income. Therefore, no provision or
liability for federal income taxes is reflected in the accompanying financial
statements.

 Use of Estimates in the Financial Statements

  The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual amounts could differ from these amounts.

NOTE 2--Pension Plan

  The Company has a non-contributory pension plan for all eligible employees.
Contributions are made at the discretion of management and totaled $35,791 for
the year ended December 31, 1997.

NOTE 3--Commitments and Related Party Transactions

 Related Party Transactions/Land Lease

  The Company rented the land that the tower is located on without a formal
lease agreement from the stockholders of the Company through July 1997. During
the year ended December 31, 1997, rent expense amounted to $91,800.

NOTE 3--Commitments and Related Party Transactions, continued

 Operating Lease

  The Company also rents office space on a month-to-month basis from an
unrelated entity. Rent expense amounted to $15,730 for the year ended December
31, 1997.

NOTE 4--Subsequent Event

  On May 7, 1998, the Company sold certain assets in the amount of $7,250,000
to an unrelated company. Pursuant to the agreement, the purchase price of the
assets can not exceed $8,500,000 based on the subsequent payments as per the
agreement.

               Report of Independent Certified Public Accountant

To the Stockholders of Long Island Waves, Inc.:

  I have audited the accompanying Statements of income and retained earnings
Long Island Waves, Inc. (a New York corporation) and Cash Flow for the period

standards. Those standards require that I 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 overall financial statement
presentation. I believe that my audit provides a reasonable basis for my
opinion.

  In my opinion, the financial statements of Long Island Waves, Inc. referred
to above present fairly, in all material respects, the results of the

                         NOTES TO FINANCIAL STATEMENTS

                               September 30, 1998
1. Nature of Business and Basis of Presentation

 Nature of Business

  Long Island Waves, Inc., a New York Corporation, hereinafter referred to as
L.I. Waves owns a telecommunication tower in the State of New York and leases
space on this tower to customers in the wireless communications industries in
New York.

  On September 30, 1998 SBA TOWERS NEW YORK, INC., Inc. a Florida Corporation,
acquired all of the outstanding common stock of L.I. Waves.

 Basis of Presentation

  The financial statements of L.I. Waves have been developed from the
accounting records of L.I. Waves, Inc. and represent a short accounting period
covering from December 1, 1997 to September 30, 1998. L.I. Waves normal fiscal
year usually commenced on December 1st and ended on November 30th in all prior
years.

2. Summary of Significant Accounting Policies

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and use assumptions
that affect the reported amounts of assets and liabilities and the disclosure
for contingent assets and liabilities at the date of the financial statements
as well as the reported amounts of revenues and expenses during the reporting
period. Actual results may vary from those estimates.

 Tower Assets

  Tower assets consist of towers, buildings, and related attachments which are
recorded at cost and depreciated using the straight-line method over the
estimated useful life of the assets, which range from five (5) to thirty-nine
(39) years. Improvements, renewals, and extraordinary repairs which increase
the value or extend the life of the asset are capitalized. Repairs and
maintenance costs are expensed as incurred.

 Impairment of Long-lived Assets

  L.I. Waves evaluates the recoverability of its long-lived assets whenever
adverse events or changes in business climate indicate that the expected
undiscounted future cash flows from the related asset may be less than
previously anticipated. If the net book value of the related asset exceeds the
undiscounted future cash flows of the asset, the carrying amount would be
reduced to the present value of its expected future cash flows and an
impairment loss would be recognized. As of September 30, 1998, management does
not believe that an impairment reserve is required.

 Fair Value of Financial Instruments

  The carrying amount of L.I. Waves financial instruments as at September 30,
1998 which include accounts receivable, prepaid expenses and short term debt,
approximates fair value due to the short maturity of those investments.

 Revenue Recognition

  Rental revenue is recognized on a straight line basis over the life of the
related lease agreements. Revenue is recorded in the month in which it is due.

                               September 30, 1998

 Direct Tower Costs

  The accompanying financial statements include certain costs and expenses that
have been directly charged to tower operating costs in arriving at Gross
Margin. (See Note 6)

 Income Taxes

  L.I. Waves accounts for income taxes using the liability method as required
by Statement No. 109, Accounting for Income Taxes, issued by the Financial
Accounting Standards Board. Deferred income taxes are provided for temporary
differences between the basis of assets and liabilities for financial reporting
and income tax reporting. As a result of the acquisition of L.I. Waves by SBA
Towers of New York, Inc., L.I. Waves taxable year terminated on the date of the
acquisition, creating a short taxable year ending September 30, 1998 (IRC Reg.
Sec. 1.1502-76(b)(2)(i)). The applicable Federal and NYS tax returns were filed
and SBA Towers New York, Inc. has been furnished copies thereof which include
prepaid income taxes, carryforward losses and contributions. (See Note 8)

3. Commitments and Contingencies

  The Company is obligated under two non-cancelable leases for land which
expire March 14, 2008 and September 30, 2006. The leases have no renewal
options. The future minimum lease commitments under these leases are as
follows:

evidence supporting the amounts and disclosures in the statements of income and
cash flows. An audit also includes assessing the accounting principles used and

      (A carve-out entity of Quad States Towers and Communications, Inc.)

                         NOTES TO FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies:

 a. Business Activity

  Quad States Towers and Communications (A carve-out entity of Quad States
Towers and Communications, Inc.) is incorporated in Minnesota primarily to
lease tower and equipment usage from towers located in Minnesota, Iowa, South
Dakota and Nebraska.

 b. Basis of Accounting

  The Company uses the accrual method of accounting for financial statements
and income tax purposes.

 c. Use of Estimates

  Management uses estimates and assumptions in preparing financial statements.
Those estimates and assumptions affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities, and the
reported revenues and expenses.

 d. Cash

  Cash equivalents are included in cash. The Company considers interest bearing
investments due on demand as cash equivalents.

 e. Depreciation

  Depreciation is computed by using both the straight-line and accelerated
methods at statutory rates which approximate their estimated useful lives.

 f. Income Taxes

  Income taxes are provided for the tax effects of transactions reported in the
financial statements and consist of taxes currently due.

2. Rental Income Under Operating Leases:

  The Company is a lessor of certain tower and equipment usage over terms
ranging from one to twenty-five years. Some leases contain option renewal
periods. These leases are accounted for as operating leases under which rental
revenues are recognized ratably over the life of the lease and the related
towers and equipment are depreciated over their estimated useful lives.
Following is a schedule of future rental income to be received under operating
leases, without the benefit of contractual consumer price index increases as
these percentages are not determinable, in effect as of June 30, 1998:

  The Company incurred a capital loss of $2,245 for the year ended June 30,
1998, which is available to carry forward and offset future capital gains. Due

</TABLE>

4. Major Customers:

  The Company generates a significant amount of its tower rental income from a
small number of companies totaling approximately sixteen. While one individual
customer accounts for approximately 22% of rental revenues which is significant
to total revenues, due to the limited number of companies serviced any
particular combination or group of accounts provide a significant portion of
revenues.

5. Concentrations:

  The Company derives the majority of its revenues from businesses requiring
internal communications transmissions or reselling communications access. The
Company grants credit to these customers in the normal course of business.

Item 14. Indemnification of Directors and Officers

Under the Florida Business Corporation Act (the "FBCA"), a director is not
personally liable for monetary damages to the corporation or any other person
for any statement, vote, decision, or failure to act regarding corporate
management or policy unless (1) the director breached or failed to perform his
duties as a director and (2) the director's breach of, or failure to perform,
those duties constitutes: (a) a violation of the criminal law, unless the
director had reasonable cause to believe his conduct was lawful or had no
reasonable cause to believe his conduct was unlawful, (b) a transaction from
which the director derived an improper personal benefit, either directly or
indirectly, (c) a circumstance under which an unlawful distribution is made,
(d) in a proceeding by or in the right of the corporation to procure a judgment
in its favor or by or in the right of a shareholder, conscious disregard for
the best interest of the corporation, or willful misconduct, or (e) in a
proceeding by or in the right of someone other than the corporation or a
shareholder, recklessness or an act or omission which was committed in bad
faith or with malicious purpose or in a manner exhibiting wanton and willful
disregard of human rights, safety, or property. A corporation may purchase and
maintain insurance on behalf of any director or officer against any liability
asserted against him or her and incurred by him or her in his or her capacity
or arising out of his or her status as such, whether or not the corporation
would have the power to indemnify him or her against such liability under the
FBCA.

Under the FBCA, a corporation has power to indemnify any person who was or is a
party to any proceeding (other than an action by, or in the right of the
corporation), by reason of the fact that he is or was a director, officer,
employee or agent of the corporation or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against liability
incurred in connection with such proceeding, including any appeal thereof, if
he acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. The termination of any proceeding by judgment, order, settlement
or conviction or upon a plea of nolo contendere or its equivalent does not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in, or not opposed to, the best
interests of the corporation or, with respect to any criminal action or
proceeding, has reasonable cause to believe that his conduct was unlawful.

                                      II-1
<PAGE>

However, indemnification or advancement of expenses shall not be made to or on
behalf of any director, officer, employee or agent if a judgment or other final
adjudication establishes that his actions, or omissions to act, were material
to the cause of action so adjudicated and constitute: (a) a violation of the
criminal law, unless the director, officer, employee or agent had reasonable
cause to believe his conduct was lawful or had no reasonable cause to believe
his conduct was unlawful; (b) a transaction from which the director, officer,
employee or agent derived an improper personal benefit; (c) in the case of a
director, a circumstance under which the above liability provisions are
applicable; or (d) willful misconduct or a conscious disregard for the best
interests of the corporation in a proceeding by or in the right of the
corporation to procure a judgment in its favor or in a proceeding by or in the
right of a shareholder.

The articles of incorporation of the Company provide that the Company shall, to
the fullest extent permitted by applicable law and its by-laws, as amended from
time to time, indemnify all officers and directors of the Company.

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable.

Item 15. Recent Sales of Unregistered Securities

In each of the sales described below, unless otherwise indicated, the Company
(or the relevant predecessor) relied on Section 4(2) of the Securities Act of
1933 for exemption from registration. No brokers or underwriters were used in
connection with any of such sales. The recipients of securities in each such
transaction represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof and appropriate legends were affixed to the share
certificates, warrants and notes issued in such transactions. All recipients
had adequate access, through their relationship with the Company, to
information about the Company.

Through March 31, 1999, the Company had raised approximately $180.2 million
through private sales of debt and equity securities in a series of private
placements with various institutional and other accredited investors and
certain employees of the Company as described below.

The 1997 Corporate Reorganization. In March 1997, Steven E. Bernstein, at that
time the sole shareholder of SBA, Inc. and SBA Leasing, Inc., as well as the
Chief Executive Officer of SBA, contributed all of the outstanding stock of SBA
Inc. and SBA Leasing, Inc. to SBA in exchange for 8,075,000 shares of SBA's
Class B common stock. Also in March 1997, Ronald G. Bizick, II, at that time
SBA's Executive Vice President-Sales and Marketing, voluntarily terminated
options he owned in SBA Inc. and SBA Leasing, Inc., (along with existing
employment and incentive agreements) in exchange for 176,472 shares of Class A
common stock of SBA and immediately exercisable options to purchase an
additional 773,528 shares of Class A common stock of SBA. Also in March 1997,
Robert M. Grobstein, at that time SBA's Chief Financial Officer, voluntarily
terminated options he owned in SBA Inc. and SBA Leasing, Inc., (along with
existing employment and incentive agreements) in exchange for 88,236 shares of
Class A common stock of SBA and immediately exercisable options to purchase an
additional 386,764 shares of Class A common stock. On March 7, 1997, SBA
redeemed the outstanding shares of its Class A common stock from Messrs. Bizick
and Grobstein for $8.50 per share. As a result of these transactions, SBA, Inc.
and SBA Leasing, Inc., became wholly-owned subsidiaries of SBA.

The Series A Preferred Stock Investment. In March 1997, the Company sold
8,050,000 shares of 4% Series A Preferred Stock, convertible initially into one
share of the Company's Class A common stock and one share of the Company's 4%
Series B Redeemable Preferred Stock, to a syndicate of institutional investors
who were accredited investors, (as such term is defined in Rule 501(a) of
Regulation D of the Securities Act) including ABS and TA Associates. BT Alex.
Brown Incorporated acted as the exclusive agent of the Company in connection
with the preferred stock offering. The Series A preferred stock had a
conversion price of $3.73. In

                                      II-2
<PAGE>


connection with the preferred stock offering, the Company also agreed to issue
to BT Alex. Brown a warrant to purchase 402,500 shares of its Class A common
stock, exercisable at $3.73 per share at any time up to March, 2002. An
affiliate of BT Alex. Brown is a limited partner in ABS. Certain officers and
employees of BT Alex. Brown are direct and indirect holders of Series A
preferred stock.

The 12% Senior Discount Notes due 2008. On March 2, 1998, the Company privately
placed, under Rule 144A of the Securities Act, $269 million aggregate principal
amount at maturity ($150,236,500 initial accreted value) of its 12% Senior
Discount Notes due 2008, yielding net proceeds to the Company of approximately
$144.5 million after deducting discounts and estimated transaction fees and
expenses. BT Alex. Brown and Lehman Brothers Inc. were the initial purchasers
of such securities. Pursuant to an effective registration statement, on
September 11, 1998, the Company exchanged $269 million aggregate principal
amount at maturity of its registered 12% Senior Discount Notes due 2008 for all
of its outstanding unregistered 12% Senior Discount Notes due 2008.

Class A Common Stock Grant to Executive Officers. On December 31, 1998, the
Company granted to Mr. Bernstein, as his bonus compensation for 1998, 51,609
shares of its Class A common stock. On December 31, 1998, the Company also
granted to Mr. Simkin, its Chief Operating Officer, as his bonus compensation

Schedule I--Condensed Financial Information of Registrant

All other schedules are omitted because they are not applicable or because the
required information is contained in the financial statements or notes thereto
included in this Registration Statement.

Item 17. Undertakings

Insofar as indemnification for liabilities arising under the Securities Act of
1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issues.

The undersigned Registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

proposes to sell to the underwriters named in Schedule 1 hereto (the
"Underwriters"), for whom Lehman Brothers Inc., Deutsche Bank Securities Inc.,
Donaldson, Lufkin & Jenrette Securities Corporation and Salomon Smith Barney

          In addition, the Company proposes to grant to the Underwriters an

further amendments or supplements to the Registration Statement or the
Prospectus will, when they become effective or are filed with the Commission, as
the case may be, conform in all material respects to the requirements of the
Securities Act and the Rules and Regulations and do not and will not, as of the
applicable effective date (as to the Registration Statement and any amendment
thereto) and as of the applicable filing date (as to the Prospectus and any
amendment or supplement thereto) contain an untrue statement of a material fact

make the statements therein not misleading; provided that no representation or
warranty is made as to information contained in or omitted from the Registration
Statement or the Prospectus in reliance upon and in conformity with written

standing under the laws of their respective jurisdictions of incorporation, are

any such court or governmental agency or body is required for the execution,

obtain would not have a material adverse effect on the general affairs,
management, consolidated financial position, stockholders' equity, results of
operations, business or prospects of the Company and its subsidiaries taken as a

such property and do not materially interfere with the use made and proposed to
be made of such property by the Company and its subsidiaries; all assets held
under lease by the Company and its subsidiaries are held by them under valid,
subsisting and enforceable leases, with such exceptions as are not material and
do not materially interfere with the use made and proposed to be made of such

the present and contemplated use of the assets owned or leased by the Company or
any of its subsidiaries for the operation of towers is in compliance in all
material respects with all applicable zoning ordinances and regulations and
other laws and regulations where failure so to comply would result, or create
reasonable risk of resulting, in a Material Adverse Effect.

rights of others, in each case except as could not reasonably be expected to
have a Material Adverse Effect.

          (q)  There are no legal or governmental proceedings pending to which
the Company or any of its subsidiaries is a party or of which any property or
assets of the Company or any of its subsidiaries is the subject which, if
determined adversely to the Company or any of its subsidiaries, might have a
Material Adverse Effect; and to the best of the Company's knowledge, no such
proceedings are threatened or contemplated by governmental authorities or
threatened by others.

          (r)  There are no contracts or other documents which are required to
be described in the Prospectus or filed as exhibits to the Registration
Statement by the Securities Act or by the Rules and Regulations which have not
been described in the Prospectus or filed as exhibits to the Registration
Statement.

          (s)  No material relationship, direct or indirect, exists between or
among the Company or the Principal Subsidiary on the one hand, and the
directors, officers, shareholders, customers or suppliers of the Company or the
Principal Subsidiary on the other hand, which is required to be described in the

withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the Internal

interpretations thereunder (the "Code"); and each "pension plan" for which the
Company would have any liability that is intended to be qualified under Section
401(a) of the Code is so qualified in all material respects and nothing has
occurred, whether by action or by failure to act, which would cause the loss of
such qualification.

          (v)  The Company has filed all federal, state and local income and
franchise tax returns required to be filed through the date hereof and has paid
all taxes due thereon, and no tax deficiency has been determined adversely to

any knowledge of any tax deficiency which, if determined adversely to the
Company or any of its subsidiaries, might have) a Material Adverse Effect.

          (w)  Since the date as of which information is given in the Prospectus
through the date hereof, and except as may otherwise be disclosed in the

violation of its charter or by-laws, (ii) is in default in any material respect,
and no event has occurred which, with notice or lapse of time or both, would
constitute such a default, in the due performance or observance of any term,
covenant or condition contained in any material indenture, mortgage, deed of
trust, loan agreement or other agreement or instrument to which it is a party or
by which it is bound or to which any of its properties or assets is subject or
(iii) is in violation in any material respect of any law, ordinance,

          (z)   Neither the Company nor any of its subsidiaries, nor any

other unlawful payment.

          (aa)  There has been no storage, disposal, generation, manufacture,
refinement, transportation, handling or treatment of toxic wastes, medical
wastes, hazardous wastes or hazardous substances by the Company or any of its
subsidiaries (or, to the knowledge of the Company, any of their predecessors in
interest) at, upon or from any of the property now or previously owned or leased
by the Company or its subsidiaries in violation of any applicable law,
ordinance, rule, regulation, order, judgment, decree or permit or which would
require remedial action under any applicable law, ordinance, rule, regulation,
order, judgment, decree or permit, except for any violation or remedial action
which would not have, or could not be reasonably likely to have, singularly or
in the aggregate with all such violations and remedial actions, a Material
Adverse Effect; there has been no material spill, discharge, leak emission,
injection, escape, dumping or release of any kind onto such property or into the
environment surrounding such property of any toxic wastes, medical wastes, solid
wastes, hazardous wastes or hazardous substances due to or caused by the Company
or any of its subsidiaries or with respect to which the Company or any of its
subsidiaries have knowledge, except for any such spill, discharge, leak,
emission, injection, escape, dumping or release which would not have or would

spills, discharges, leaks, emissions, injections, escapes, dumpings and
releases, a Material Adverse Effect; and the terms "hazardous wastes", "toxic

specified in any applicable local, state, federal and foreign laws or
regulations with respect to environmental protection.

          (bb)  Neither the Company nor any subsidiary is, or upon application
of the net proceeds from the sale of the Stock as set forth in the Prospectus,
will be, an "investment company" as defined in the Investment Company Act of

          (cc)  Any reprogramming required to permit the proper functioning, in
and following the year 2000, of (i) the Company's computer systems and (ii)
equipment containing embedded microchips (including systems and equipment
supplied by others or with which the Company's systems interface) and the
testing of all such systems and equipment, as so reprogrammed, will be completed
by September 30, 1999. The cost to the Company of such reprogramming and testing
and of the reasonably foreseeable consequences of year 2000 to the Company
(including, without limitation, reprogramming errors and the failure of others'
systems or equipment) will not result in a Material Adverse Effect. Except for
such of the reprogramming referred to in the preceding sentence as may be
necessary, the computer and management information systems of the Company and
its subsidiaries are and, with ordinary course upgrading and maintenance, will
continue to be, sufficient to permit the Company to conduct its business without
a Material Adverse Effect.

compliance with all such laws, rules, regulations and ordinances, including
those promulgated by the FCC and the FAA, to the extent the non-compliance with

          (ff)  For each existing tower of the Company (or of its subsidiaries)
not yet registered with the FCC where registration will be required, the FCC's
grant of an application for registration of such tower will not have a
significant environmental effect as defined under Section 1.1307(a) of the FCC's
rules.

          (gg)  Neither the Company, nor to its knowledge, any of its
affiliates, has taken, directly or indirectly, any action designed to cause or

          In addition, the Company grants to the Underwriters an option to

exercisable as provided in Section 5 hereof. Shares of Option Stock shall be
purchased severally for the account of the Underwriters in proportion to the
number of shares of Firm Stock set forth opposite the name of such Underwriters
in Schedule 1 hereto. The respective purchase obligations of each Underwriter
with respect to the Option Stock shall be adjusted by the Representatives so
that no Underwriter shall be obligated to purchase Option Stock other than in

          The price of both the Firm Stock and any Option Stock shall be $[

          The Company shall not be obligated to deliver any of the Stock to be
delivered on any Delivery Date (as hereinafter defined), except upon payment for
all the Stock to be purchased on such Delivery Date as provided herein.

or at such other date or place as shall be determined by agreement between the
Representatives and the Company. This date and time are sometimes referred to as
the "First Delivery Date." On the First Delivery Date, the Company shall deliver
or cause to be delivered certificates representing the Firm Stock to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company of the purchase price by wire transfer in immediately
available funds. Time shall be of the essence, and delivery at the time and
place specified pursuant to this Agreement is a further condition of the
obligation of each Underwriter hereunder. Upon delivery, the Firm Stock shall be
registered in such names and in such denominations as the Representatives shall
request in writing not less than two full business days prior to the First
Delivery Date. For the purpose of expediting the checking and packaging of the
certificates for the Firm Stock the Company shall make the certificates

written notice being given to the Company by the Representatives.  Such notice
shall set forth the aggregate number of shares of Option Stock as to which the
option is being exercised, the names in which the shares of Option Stock are to
be registered, the denominations in which the shares of Option Stock are to be
issued and the date and time, as determined by the Representatives, when the
shares of Option Stock are to be delivered; provided, however, that this date
and time shall not be earlier than the First Delivery Date nor earlier than the
second business day after the date on

which the option shall have been exercised nor later than the fifth business day
after the date on which the option shall have been exercised. The date and time
the shares of Option Stock are delivered are sometimes referred to as a "Second
Delivery Date" and the First Delivery Date and any Second Delivery Date are
sometimes each referred to as a "Delivery Date".

          Delivery of and payment for the Option Stock shall be made at the
place specified in the first sentence of the first paragraph of this Section 5
(or at such other place as shall be determined by agreement between the
Representatives and the Company) at 10:00 A.M., New York City time, on such

to the Representatives for the account of each Underwriter against payment to or

printing and filing under the Securities Act of the Registration Statement and
any amendments and exhibits thereto; (c) the costs of distributing the

post-effective amendments thereof (including, in each case, exhibits), any
Preliminary Prospectus, the Prospectus and any amendment or supplement to the
Prospectus, all as provided in this Agreement; (d) the filing fees incident to
securing the review by the NASD of the terms of sale of the Stock; (e) any
applicable listing or other fees; (f) the fees and expenses of qualifying the
Stock under the securities laws of the several jurisdictions as provided in

of the obligations of the Company under this Agreement; provided that, except as
provided in this Section 8 and in Section 13, the Underwriters shall pay their
own costs and expenses, including the costs and expenses of their counsel, any
transfer taxes on the Stock which they may sell and the expenses of advertising
any offering of the Stock made by the Underwriters.

          Notwithstanding the foregoing, the Underwriters agree to pay the costs
and expenses of the Company relating to investor presentations on any "road
show" undertaken in connection with the marketing of the offering of the Stock,
including, without limitation, expenses associated with the production of road
show slides and graphics, fees and expenses of any consultants engaged in
connection with the road show presentations, travel and lodging expenses of the
representatives of the Company and any such consultants, and the cost of any
aircraft chartered in connection with the road show.

          SECTION 9.  Conditions of Underwriters' Obligations.  The respective
obligations of the Underwriters hereunder are subject (x) to the accuracy when
made and on each Delivery Date, of the representations and warranties of the
Company and the Principal Subsidiary contained herein (provided, that in the
                                                       --------
case of this clause (x), the obligations of the Underwriters hereunder shall be

warranties that are not qualified by material adverse effect), (y) to the
performance in all material respects by the Company of its obligations hereunder
and (z) to each of the following additional terms and conditions:

have been complied with.

          (b)  No Underwriter shall have discovered and disclosed to the Company
on or prior to the First Delivery date that the Registration Statement or the
Prospectus or any amendment or supplement thereto contains an untrue statement
of fact which, in the opinion of Simpson Thacher & Bartlett, counsel for the
Underwriters, is material or omits to state a fact
<PAGE>

                                                                              14

which, in the opinion of such counsel, is material and is required to be stated
therein or is necessary to make the statements therein not misleading.

          (c)  All corporate proceedings and other legal matters incident to the
authorization, form and validity of this Agreement, the Stock, the Registration
Statement and the Prospectus, and all other legal matters relating to this
Agreement and the transactions contemplated hereby shall be reasonably

Company shall have furnished to such counsel all documents and information that
they may reasonably request to enable them to pass upon such matters.

          (d) Latham & Watkins shall have furnished to the Representatives its
written opinion, as counsel to the Company, addressed to the Underwriters and

          (e) Gunster, Yoakley, Valdes-Fauli & Stewart P.A. shall have furnished

require, and the Company shall have furnished to such counsel such documents as
they reasonably request for the purpose of enabling them to pass upon such
matters.

          (g)  At the time of execution of this Agreement, the Representatives
shall have received from Arthur Andersen LLP a letter, in form and substance
satisfactory to the Representatives, addressed to the Underwriters and dated the
date hereof (i) confirming that they are independent public accountants within
the meaning of the Securities Act and are in compliance with the applicable
requirements relating to the qualification of accountants under Rule 2-01 of
Regulation S-X of the Commission and (ii) stating, as of the date hereof (or,
with respect to matters involving changes or developments since the respective
dates as of which specified financial information is given in the Prospectus, as
of a date not more than five days prior to the date hereof), the conclusions and
findings of such firm with respect to the financial information and other
matters ordinarily covered by accountants' "comfort letters" to underwriters in
connection with registered public offerings.

          (h)  With respect to the letter of Arthur Andersen LLP referred to in

of the Commission, (ii) stating, as of the date of the bring-down letter (or,
with respect to matters involving changes or
<PAGE>

                                                                              15

developments since the respective dates as of which specified financial
information is given in the Prospectus, as of a date not more than five days
prior to the date of the bring-down letter), the conclusions and findings of
such firm with respect to the financial information and other matters covered by
the initial letter and (iii) confirming in all material respects the conclusions
and findings set forth in the initial letter.

          (i)  The Company shall have furnished to the Representatives a
certificate, dated such Delivery Date, of its Chairman of the Board or its
President and its chief financial officer stating that:

          (i)  The representations, warranties and agreements of the Company and
     the Principal Subsidiary in Section 1 are true and correct as of such
     Delivery Date (provided, that such representations, warranties and
                    --------
     agreements that are not qualified by material adverse effect shall be true
     and correct in all material respects); the Company has complied in all
     material respects with all its agreements contained herein; and the
     conditions set forth in Sections 9(a), 9(j) and 9(k) have been fulfilled;
     and

          (ii) They have carefully examined the Registration Statement and the
     Prospectus and, in their opinion (A) as of the Effective Date, the
     Registration Statement and the Prospectus did not include any untrue
     statement of a material fact and did not omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, and (B) since the Effective Date no event has occurred
     which should have been set forth in a supplement or amendment to the
     Registration Statement or the Prospectus.

          (j)  Neither the Company nor any of its subsidiaries shall have
sustained since the date of the latest audited financial statements included in
the Prospectus (i) any material loss or interference with its business from
fire, explosion, flood or other calamity, whether or not covered by insurance,
or from any labor dispute or court or governmental action, order or decree,
otherwise than as set forth or contemplated in the Prospectus or (ii) since such
date there shall not have been any change in the capital stock or long-term debt
of the Company on a consolidated basis or any material adverse change, or any
development involving a prospective change, in or affecting the general affairs,
management, financial position, stockholders' equity or results of operations of
the Company and its subsidiaries, otherwise than as set forth or contemplated in
the Prospectus, the effect of which, in any such case described in clause (i) or
(ii), is, in the judgment of the Representatives, so material and adverse as to
make it impracticable or inadvisable to proceed with the public offering or the
delivery of the Stock being delivered on such Delivery Date on the terms and in
the manner contemplated in the Prospectus.

          (k)  Subsequent to the execution and delivery of this Agreement (i) no
downgrading shall have occurred in the rating accorded the Company's debt
securities by any "nationally recognized statistical rating organization", as
that term is defined by the Commission for purposes of Rule 436(g)(2) of the
Rules and Regulations and (ii) no such organization shall have publicly
announced that it has under surveillance or review, with possible negative
implications, its rating of any of the Company's debt securities.

          (l)  Subsequent to the execution and delivery of this Agreement there
shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange or the American Stock Exchange or in
the over-the-counter market, or trading in any securities of the Company on any
exchange or in the over-the-counter market, shall have been suspended or minimum
prices shall have been established on any such exchange or such market by the
Commission, by such exchange or by any other regulatory body or governmental
authority having jurisdiction, (ii) a banking moratorium shall have been
declared by Federal or state authorities, (iii) the United States shall have
become engaged in hostilities, there shall have been an escalation in
hostilities involving the United States or there shall have been a declaration
of a national emergency or war by the United States or (iv) there shall have
occurred such a material adverse change in general economic, political or
financial conditions (or the effect of international conditions on the financial
markets in the United States shall be such) as to make it, in the judgment of
the Representatives, impracticable or inadvisable to proceed with the public
offering or delivery of the Stock being delivered on such Delivery Date on the
terms and in the manner contemplated in the Prospectus.

          (m)  The National Market System shall have approved the Stock for
listing, subject only to official notice of issuance and evidence of
satisfactory distribution.

          (n) The Representatives shall have received from each officer,
director and shareholder of the Company owning at least 10,000 shares of Common
Stock or common stock equivalents or options exercisable within 180 days of the
date of the final Prospectus to acquire at least 10,000 shares of Common Stock
an executed letter in the form of Exhibit E pursuant to Section 6(i) hereto.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

          SECTION 10.  Indemnification and Contribution.

          (a)  The Company and the Principal Subsidiary, jointly and severally,
shall indemnify and hold harmless each Underwriter (including any Underwriter in
its role as a qualified independent underwriter pursuant to the rules of the
National Association of Securities Dealers, Inc.), its officers and employees
and each person, if any, who controls any Underwriter within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof (including, but not limited to, any
loss, claim, damage, liability or action relating to purchases and sales of
Stock), to which that Underwriter, officer, employee or controlling person may
become subject, under the Securities Act or otherwise, insofar as such loss,
claim, damage, liability or action arises out of, or is based upon, (i) any
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus or in any
amendment or supplement thereto, (ii) the omission or alleged omission to state
in any Preliminary Prospectus, the Registration Statement or the Prospectus, or
in any amendment or supplement thereto, or in any Blue Sky application, any
material fact required to be stated therein or necessary to make the statements
therein not misleading or (iii) any act or failure to act or any alleged act or
failure to

                                                                              17

act by any Underwriter in connection with, or relating in any manner to, the
Stock or the offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or action arising out of or
based upon matters covered by clause (i) or (ii) above (provided that the
Company and the Principal Subsidiary shall not be liable under this clause (iii)
to the extent that it is determined in a final judgment by a court of competent
jurisdiction that such loss, claim, damage, liability or action resulted
directly from any such acts or failures to act undertaken or omitted to be taken
by such Underwriter through its gross negligence or willful misconduct), and
shall reimburse each Underwriter and each such officer, employee or controlling
person promptly upon demand for any legal or other expenses reasonably incurred
by that Underwriter, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company and the Principal Subsidiary shall not be liable in any such
case to the extent that any such loss, claim, damage, liability or action arises
out of, or is based upon, any untrue statement or alleged untrue statement or
omission or alleged omission made in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or in any such amendment or
supplement, in reliance upon and in conformity with written information
concerning such Underwriter furnished to the Company through the Representatives
by or on behalf of any Underwriter specifically for inclusion therein which
information consists solely of the information specified in Section 10(e). The
foregoing indemnity agreement is in addition to any liability which the Company
may otherwise have to any Underwriter or to any officer, employee or controlling
person of that Underwriter.

          (b)  Each Underwriter, severally and not jointly, shall indemnify and
hold harmless the Company, its officers and employees, each of its directors,
and each person, if any, who controls the Company within the meaning of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company or any such
director, officer or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained (A) in any Preliminary Prospectus, the
Registration Statement or the Prospectus or in any amendment or supplement
thereto, or (B) in any Blue Sky Application or (ii) the omission or alleged
omission to state in any Preliminary Prospectus, the Registration Statement or
the Prospectus, or in any amendment or supplement thereto, any material fact
required to be stated therein or necessary to make the statements therein not
misleading, but in each case only to the extent that the untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information concerning such Underwriter
furnished to the Company through the Representatives by or on behalf of that
Underwriter specifically for inclusion therein, and shall reimburse the Company
and any such director, officer or controlling person for any legal or other
expenses reasonably incurred by the Company or any such director, officer or
controlling person in connection with investigating or defending or preparing to
defend against any such loss, claim, damage, liability or action as such
expenses are incurred.  The foregoing indemnity agreement is in addition to any
liability which any Underwriter may otherwise have to the Company or any such
director, officer, employee or controlling person.
<PAGE>

                                                                              18

          (c)  Promptly after receipt by an indemnified party under this Section
10 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 10, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 10 except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 10.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party.  After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be liable
to the indemnified party under this Section 10 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the Representatives shall have the right to employ counsel to represent jointly
the Representatives and those other Underwriters and their respective officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Underwriters
against the Company or the Principal Subsidiary under this Section 10 if, in the
reasonable judgment of the Representatives, it is advisable for the
Representatives and those Underwriters, officers, employees and controlling
persons to be jointly represented by separate counsel, and in that event the
fees and expenses of such separate counsel shall be paid by the Company or the
Principal Subsidiary.  No indemnifying party shall (i) without the prior written
consent of the indemnified parties (which consent shall not be unreasonably
withheld), settle or compromise or consent to the entry of any judgment with
respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified parties are actual or potential parties to such
claim or action) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action, suit or proceeding, or (ii) be liable for any settlement
of any such action effected without its written consent (which consent shall not
be unreasonably withheld), but if settled with the consent of the indemnifying
party or if there be a final judgment of the plaintiff in any such action, the
indemnifying party agrees to indemnify and hold harmless any indemnified party
from and against any loss or liability by reason of such settlement or judgment.

          (d)  If the indemnification provided for in this Section 10 shall for
any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 10(a) or 10(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Principal Subsidiary on the one hand and the
Underwriters on the other from the offering of the Stock or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is
<PAGE>

                                                                              19

appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company or the Principal Subsidiary on
the one hand and the Underwriters on the other with respect to the statements or
omissions which resulted in such loss, claim, damage or liability, or action in
respect thereof, as well as any other relevant equitable considerations. The
relative benefits received by the Company and the Principal Subsidiary on the
one hand and the Underwriters on the other with respect to such offering shall
be deemed to be in the same proportion as the total net proceeds from the
offering of the Stock purchased under this Agreement (before deducting expenses)
received by the Company and the Principal Subsidiary, on the one hand, and the
total underwriting discounts and commissions received by the Underwriters with
respect to the shares of the Stock purchased under this Agreement, on the other
hand, bear to the total gross proceeds from the offering of the shares of the
Stock under this Agreement, in each case as set forth in the table on the cover
page of the Prospectus. The relative fault shall be determined by reference to
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company, the Principal Subsidiary, or the Underwriters, the intent of the
parties and their relative knowledge, access to information and opportunity to
correct or prevent such statement or omission. For purposes of the preceding two
sentences, the net proceeds deemed to be received by the Company shall be deemed
to be also for the benefit of the Principal Subsidiary and information supplied
by the Company shall also be deemed to have been supplied by the Principal
Subsidiary. The Company, the Principal Subsidiary and the Underwriters agree
that it would not be just and equitable if contributions pursuant to this
Section were to be determined by pro rata allocation (even if the Underwriters
were treated as one entity for such purpose) or by any other method of
allocation which does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section shall be deemed to include, for purposes of
this Section 10(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 10(d), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Stock underwritten by it and distributed to the public
was offered to the public exceeds the amount of any damages which such
Underwriter has otherwise paid or become liable to pay by reason of any untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 1l(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations to
contribute as provided in this Section 10(d) are several in proportion to their
respective underwriting obligations and not joint.

          (e)  The Underwriters severally confirm and the Company acknowledges
that the statements with respect to the public offering of the Stock by the
Underwriters set forth on the cover page of and the concession and reallowance
figures and the statements concerning over-allotments appearing under the
caption "Underwriting" in, the Prospectus are correct and constitute the only
information concerning such Underwriters furnished in writing to the Company by
or on behalf of the Underwriters specifically for inclusion in the Registration
Statement and the Prospectus.
<PAGE>

                                                                              20

          SECTION 11.  Defaulting Underwriters.

          If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining non-
defaulting Underwriters shall be obligated to purchase the Stock which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of shares of the Firm Stock set
opposite the name of each remaining non-defaulting Underwriter in Schedule 1
hereto bears to the total number of shares of the Firm Stock set opposite the
names of all the remaining non-defaulting Underwriters in Schedule 1 hereto;
provided, however, that the remaining non-defaulting Underwriters shall not be
obligated to purchase any of the Stock on such Delivery Date if the total number
of shares of the Stock which the defaulting Underwriter or Underwriters agreed
but failed to purchase on such date exceeds 9.09% of the total number of shares
of the Stock to be purchased on such Delivery Date, and any remaining non-
defaulting Underwriter shall not be obligated to purchase more than 110% of the
number of shares of the Stock which it agreed to purchase on such Delivery Date
pursuant to the terms of Section 3.  If the foregoing maximums are exceeded, the
remaining non-defaulting Underwriters, or those other underwriters satisfactory
to the Representatives who so agree, shall have the right, but shall not be
obligated, to purchase, in such proportion as may be agreed upon among them, all
the Stock to be purchased on such Delivery Date.  If the remaining Underwriters
or other underwriters satisfactory to the Representatives do not elect to
purchase the shares which the defaulting Underwriter or Underwriters agreed but
failed to purchase on such Delivery Date, this Agreement (or, with respect to
the Second Delivery Date, the obligation of the Underwriters to purchase, and of
the Company to sell, the Option Stock) shall terminate without liability on the
part of any non-defaulting Underwriter or the Company except that the Company
will continue to be liable for the payment of expenses to the extent set forth
in Sections 8 and 13.  As used in this Agreement, the term "Underwriter"
includes, for all purposes of this Agreement unless the context requires
otherwise, any party not listed in Schedule 1 hereto who, pursuant to this
Section 11, purchases Firm Stock which a defaulting Underwriter agreed but
failed to purchase.

      Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default.  If
other underwriters are obligated or agree to purchase the Stock of a defaulting
or withdrawing Underwriter, either the Representatives or the Company may
postpone the Delivery Date for up to seven full business days in order to effect
any changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

          SECTION 12.  Termination.  The obligations of the Underwriters
hereunder may be terminated by the Representatives by notice given to and
received by the Company prior to delivery of and payment for the Firm Stock if,
prior to that time, any of the events described in Sections 9(j), 9(k) or 9(l),
shall have occurred or if the Underwriters shall decline to purchase the Stock
for any reason permitted under this Agreement.

          SECTION 13.  Reimbursement of Underwriters' Expense.  If the Company
shall fail to tender the Stock for delivery to the Underwriters by reason of any
failure, refusal or inability on the part of the Company to perform any
agreement on its part to be performed, or
<PAGE>

                                                                              21

because any other condition of the Underwriters' obligations hereunder required
to be fulfilled by the Company is not fulfilled (other than pursuant to Section
9(l)(iv)), the Company will reimburse the Underwriters for all reasonable
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
incurred by the Underwriters in connection with this Agreement and the proposed
purchase of the Stock and upon demand the Company shall pay the full amount
thereof to the Representatives. If this Agreement is terminated pursuant to
Section 11 by reason of the default of one or more Underwriters, the Company
shall not be obligated to reimburse any defaulting Underwriter on account of
those expenses.

          SECTION 14.  Notices, Etc.  All statements, requests, notices and
agreements hereunder shall be in writing, and:

          (a)  if to the Underwriters, shall be delivered or sent by mail, telex
or facsimile transmission to Lehman Brothers Inc., Three World Financial Center,
New York New York 10285, Attention: Syndicate Department (Fax: 212-526-6588),

          (b)  if to the Company or to the Principal Subsidiary, shall be

provided, however, that any notice to an Underwriter pursuant to Section 10(c)
shall be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its acceptance telex to the

                           LOCK-UP LETTER AGREEMENT


Lehman Brothers Inc.
Deutsche Bank Securities Inc.
Donaldson, Lufkin & Jenrette Securities Corporation
Salomon Smith Barney Inc.


As Representatives of the several
   Underwriters named in Schedule 1,
c/o Lehman Brothers Inc.
Three World Financial Center
New York New York 10285

Dear Sirs:

          The undersigned understands that you and certain other firms propose
to enter into an Underwriting Agreement (the "Underwriting Agreement") providing
for the purchase by you and such other firms (the "U.S. Underwriters") of shares
(the "Shares") of Class A common stock, par value $0.01 per share (the "Common
Stock"), of SBA Communications Corporation, a Florida corporation (the
"Company"), and that the U.S. Underwriters propose to reoffer the Shares to the
public (the "U.S. Offering").

          In consideration of the execution of the Underwriting Agreement by the
U.S. Underwriters, and for other good and valuable consideration, the
undersigned hereby irrevocably agrees that, without the prior written consent of
Lehman Brothers Inc., on behalf of the U.S. Underwriters, the undersigned will
not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise
dispose of (or enter into any transaction or device that is designed to, or
could be expected to, result in the disposition by any person at any time in the
future of) any shares of Common Stock (including, without limitation, shares of
Common Stock that may be deemed to be beneficially owned by the undersigned in
accordance with the rules and regulations of the Securities and Exchange
Commission and shares of Common Stock that may be issued upon exercise of any
option or warrant) or securities convertible into or exchangeable for Common
Stock (other than the Shares and shares issued pursuant to employee benefit
plans, qualified stock option plans or other employee compensation plans
existing on the date hereof or pursuant to currently outstanding options,
warrants or rights) or substantially similar securities owned by the undersigned
on the date of execution of this Lock-Up Letter Agreement or on the date of the
completion of the U.S. Offering, or sell or grant options, rights or warrants
with respect to any shares of Common Stock or substantially similar securities
(other than the grant of options pursuant to option plans existing on the date
hereof) or (2) enter into any swap or other derivatives transaction that
transfers to another, in whole or in part, any of the economic benefits
<PAGE>

or risks of ownership of such shares of Common Stock whether any such
transaction described in clause (1) or (2) above is to be settled by delivery of
Common Stock or other securities, in cash or otherwise, for a period of 180 days
after the date of the final Prospectus relating to the U.S. Offering.
Notwithstanding the foregoing, the undersigned shall be permitted to make (i)
gifts and other private transfers of Common Stock solely for the purpose of
estate planning and (ii) transfers of Common Stock in private transactions;
provided, that in the case of any transfer pursuant to the foregoing clauses (i)
- --------
and (ii), the transferee agrees to be bound by all of the terms and provisions
of this Lock-Up Letter Agreement.

          In furtherance of the foregoing, the Company is hereby authorized to
decline to make any transfer of securities if such transfer would constitute a
violation or breach of this Lock-Up Letter Agreement.

          It is understood that, if the Company notifies you that it does not
intend to proceed with the U.S. Offering, if the Underwriting Agreement does not
become effective, or if the Underwriting Agreement (other than the provisions
thereof which survive termination) shall terminate or be terminated prior to
payment for and delivery of the Shares, we will be released from our obligations
under this Lock-Up Letter Agreement.

          The undersigned understands that the Company and the U.S. Underwriters
will proceed with the U.S. Offering in reliance on this Lock-Up Letter
Agreement.

          Whether or not the U.S. Offering actually occurs depends on a number
of factors, including market conditions.  Any U.S. Offering will only be made
pursuant to an Underwriting Agreement, the terms of which are subject to
negotiation between the Company and the U.S. Underwriters.

          The undersigned hereby represents and warrants that the undersigned
has full power and authority to enter into this Lock-Up Letter Agreement and
that, upon request, the undersigned will execute any additional documents
necessary in connection with the enforcement hereof.  Any obligations of the
undersigned shall be binding upon the heirs, personal representatives,
successors and assigns of the undersigned.

                                        Very truly yours,

                                 Capital Stock

A.        AUTHORIZED SHARES

          The total number of shares of all classes of stock that the

Stock") and Eight Million One Hundred Thousand (8,100,000) shares shall be
classified as Class B Common Stock, par value $0.01 per share ("Class B Common
Stock") (collectively, together with the Class A Common Stock, the "Common
Stock").  The Board of Directors is expressly authorized to provide for the
classification and reclassification of any unissued shares of Common Stock or
Preferred Stock and the issuance thereof in one or more classes or series
without the approval of the stockholders of the Corporation.

B.        PROVISIONS RELATING TO COMMON STOCK

          1.  Relative Rights.  The Common Stock shall be subject to all of the
rights, privileges, preferences and priorities of the Preferred Stock as set
forth in the certificate of designations filed to establish the respective
series of Preferred Stock.  Except as provided in this Article III.B, each share
of Class A Common Stock and Class B Common Stock shall have the same relative
rights and shall be identical in all respects as to all matters.

          2.  Ownership of Class B Common Stock.

              (a)  The Corporation may issue shares of Class B Common Stock only
to Steven E. Bernstein, who may transfer such shares only to other members of

or lineal descendants of spouses, whether alive as of the date hereof or born
subsequently, any trusts or other estate planning vehicles for the benefit of
any of the foregoing, whether existing as of the date hereof or created
subsequently, or any estate or tax planning vehicles on the part of Mr.

that the Corporation may not issue any Class B Common Stock at any time after
the date on which the Corporation issues any Preferred Stock to any person other
than Mr. Bernstein. For purposes of this Article III.B.2, an entity shall be
deemed to be controlled by any person or entity who or which, directly or
indirectly, holds more than 50% of the outstanding voting rights of such entity
and has the power to direct or cause the direction of the management and
policies of such entity.

              (b)  "Immediate Family" of Mr. Bernstein shall include his spouse,
parents, children, siblings, mother and father-in-law, sons and daughters-in-
laws and brothers and sisters-in-law, or any other person who is supported,
directly or indirectly, to a material extent by Mr. Bernstein.

<PAGE>

          3.  Voting Rights.  Each holder of shares of Class A Common Stock and
Class B Common Stock shall be entitled to attend all special and annual meetings
of the stockholders of the Corporation.  On all matters upon which stockholders
are entitled or permitted to vote, every holder of Class A Common Stock shall be
entitled to cast one (1) vote in person or by proxy for each outstanding share
of Class A Common Stock standing in such holder's name on the transfer books of
the Corporation, and every holder of Class B Common Stock shall be entitled to
cast ten (10) votes in person or by proxy for each outstanding share of Class B
Common Stock standing in such holder's name on the transfer books of the
Corporation.  Except as otherwise provided in these Articles of Incorporation or
by applicable law, the holders of shares of Class A Common Stock and Class B
Common Stock shall vote together as a single class, subject to any voting rights
which may be granted to holders of Preferred Stock.

          4.  Dividends.  Whenever there shall have been paid, or declared and
set aside for payment, to the holders of shares of any class of stock having
preference over the Common Stock as to the payment of dividends, the full amount
of dividends and of sinking fund or retirement payments, if any, to which such
holders are respectively entitled in preference to the Common Stock, then the
holders of record of the Class A Common Stock and Class B Common Stock, and any
class or series of stock entitled to participate therewith as to dividends,
shall be entitled to receive dividends, when, as, and if declared by the Board
of Directors, out of any assets legally available for the payment of dividends
thereon, provided that no dividend may be declared and paid to the holders of
the Class A Common Stock unless at the same time the Board of Directors shall
also declare and pay to the holders of the Class B Common Stock a per share
dividend equal to and, subject to the next sentence, in the same form as the
dividend declared and paid to the holders of the Class A Common Stock, and vice
versa.  Dividends payable in Common Stock declared on Class A Common Stock shall
be payable in Class A Common Stock and Common Stock dividends declared on Class
B Common Stock shall be payable in Class B Common Stock.

          5.  Dissolution, Liquidation, Winding Up.  In the event of any
dissolution, liquidation or winding up of the Corporation, whether voluntary or
involuntary, the holders of record of the Class A Common Stock then outstanding
and the holders of record of the Class B Common Stock then outstanding, and all
holders of any class or series of stock entitled to participate therewith, in
whole or in part, as to distribution of assets, shall become entitled to
participate equally on a per share basis in the distribution of any assets of
the Corporation remaining after the Corporation shall have paid or provided for
payment of all debts and liabilities of the Corporation, and shall have paid, or
set aside for payment, to the holders of any class of stock having preference
over the Common Stock in the event of dissolution, liquidation or winding up,
the full preferential amounts (if any) to which they are entitled.

          6.  Conversion of Class B Common Stock.

              (a)  Conversion Events. (i) Each outstanding share of Class B
                   -----------------
Common Stock may, at the option of the holder thereof, at any time, be converted
into one fully paid and non-assessable share of Class A Common Stock. (ii) Each
share of outstanding Class B Common Stock which is transferred to any holder
other than an Eligible Class B Stock Holder shall

                                       3
<PAGE>

convert into one fully paid and non-assessable share of Class A Common Stock
immediately upon such transfer. (iii) If the shares of Class B Common Stock held
by the Eligible Class B Stock Holders in the aggregate constitute 10% or less of
the outstanding shares of Common Stock of the Corporation or upon the death or
mental incapacity of Steven E. Bernstein, each share of Class B Common Stock
shall immediately convert into one fully paid and non-assessable share of Class
A Common Stock. (iv) At such time as an Eligible Class B Stock Holder ceases to
be an Eligible Class B Stock Holder, each share of Class B Common Stock held by
such person or entity shall immediately convert into one fully paid and non-
assessable share of Class A Common Stock. (v) In the event that any shares of
Series C Preferred Stock are issued, each share of Class B Common Stock shall
immediately convert into one fully paid and non-assessable share of Class A
Common Stock.

          (b) Automatic Conversion Procedure.  In the event of any conversion of
              ------------------------------
shares of Class B Common Stock pursuant to Article III.B.6(a), the holder of
such shares of Class B Common Stock shall promptly surrender the certificate or
certificates therefor, duly endorsed in blank or accompanied by proper
instruments of transfer, at the office of the Corporation, or of any transfer
agent for such shares, and shall give written notice to the Corporation (the
"Notice"), at such office: (i) stating that shares of Class B Common Stock have
been converted into shares of Class A Common Stock as provided in this Article
III.B.6; (ii) specifying the subdivision of Article III.B.6(a) pursuant to which
the conversion occurred; (iii) identifying the number of shares of Class B
Common Stock being converted; and (iv) setting out the name or names (with
addresses) and denominations in which the certificate or certificates for shares
of Class A Common Stock shall be issued, with instructions for delivery thereof.
Delivery of such notice together with the certificates representing the shares
of Class B Common Stock shall obligate the Corporation to issue such shares of
Class A Common Stock.  Thereupon the Corporation or its agent shall promptly
issue and deliver to such holder a certificate or certificates representing the
shares to which such holder is entitled, registered in the name of such holder
or designee as specified in the Notice.  The Corporation shall take any and all
steps necessary to effect a conversion pursuant to Article III.B.6(a),
notwithstanding any failure by the holder to deliver to the Corporation the
Notice or the certificates representing the shares subject to such conversion.

          (c) Effect of Automatic Conversion.  To the extent permitted by law,
              ------------------------------
conversion shall be deemed to have been effected as of the date on which
conversion was first permitted under Article III.B.6(a) (such date being the
"Conversion Time").  The person entitled to receive shares issuable upon such
conversion shall be treated for all purposes as the record holder of such class
of shares at and as of the Conversion Time, and the right of such person as a
holder of the shares held prior to such conversion shall cease and terminate at
and as of the Conversion Time, in each case notwithstanding any failure by the
holder to deliver to the Corporation the Notice or the certificates representing
the shares subject to conversion, or the Corporation's failure to issue to the
holder certificates representing the shares to be held after the conversion has
been effected.

          (d) Reservation.  The Corporation hereby reserves and shall at all
              -----------
times reserve and keep available, out of its authorized and unissued shares of
capital stock, for the

                                       4
<PAGE>

purposes of effecting conversions, such number of duly authorized shares of
capital stock as shall from time to time be sufficient to effect the conversion
of the Class B Common Stock contemplated herein. All such shares so issuable
shall, when so issued, be duly and validly issued, fully paid and non-
assessable, and free from liens and charges with respect to the issue. The
Corporation will take all such action as may be necessary to ensure that all
such shares may be so issued without violation of any applicable law or
regulation, or of any requirements of any national securities exchange or The
Nasdaq Stock Market's National Market upon which such shares may be listed or
traded.

          7.  Subdivisions and Combinations of Shares.  If the Corporation in
any manner subdivides (by any stock split, reclassification, stock dividend,
recapitalization or otherwise) or combines the outstanding shares of one class
of Common Stock at a time when shares of the other class of Common Stock are
outstanding, the outstanding shares of the other class of Common Stock will be
likewise subdivided or combined.

          8.  Amendment of Terms of a Class of Common Stock.  Notwithstanding
any other provision of these Articles of Incorporation, any amendment to these
Articles of Incorporation implemented on or after the date of consummation of an
initial public offering of shares of Class A Common Stock that alters or changes
the powers, preferences or special rights of Class B Common Stock will require
both a separate class vote of the Class A Common Stock as to such amendment and
a separate class vote of the Class B Common Stock as to such amendment.

C.        PREFERRED STOCK

          1.  Issuance, Designations, Powers, etc. The Board of Directors
expressly is authorized, subject to limitations prescribed by the Florida

rights of priority, if any, of payment of dividends on shares of that series;

          (c) Whether that series shall have voting rights, in addition to the
voting rights provided by law, and, if so, the terms of such voting rights;

          (d) Whether that series shall have conversion privileges, and, if so,
the terms and conditions of such conversion, including provision for adjustment
of the conversion rate in such events as the Board of Directors shall determine;

                                       5
<PAGE>

          (e) Whether or not the shares of that series shall be redeemable, and,
if so, the terms and conditions of such redemption, including the dates upon or
after which they shall be redeemable, and the amount per share payable in case
of redemption, which amount may vary under different conditions and at different
redemption dates;

          (f) Whether that series shall have a sinking fund for the redemption
or purchase of shares of that series, and, if so, the terms and amount of such
sinking fund;

          (g) The rights of the shares of that series in the event of voluntary
or involuntary liquidation, dissolution or winding up of the Corporation, and
the relative rights of priority, if any, of payment of shares of that series;
and

          (h) Any other relative powers, preferences, and rights of that series,
and qualifications, limitations or restrictions on that series.

     2.   Dissolution, Liquidation, Winding Up.  In the event of any
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary, the holders of Preferred Stock of each series shall be entitled to
receive only such amount or amounts as shall have been fixed by the resolution
or resolutions of the Board of Directors providing for the issuance of such
series.

                                  ARTICLE IV.
                                  -----------

                                   Existence

        The Corporation shall exist perpetually unless sooner dissolved
according to law.

                                  ARTICLE V.
                                  ----------

                         Management of the Corporation

          The following provisions are inserted for the management of the
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and shareholders:

A.        BOARD OF DIRECTORS

          The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors.  In addition to the powers and
authority expressly conferred upon them by Statute or by these Articles of
Incorporation or the Bylaws of the Corporation, the directors are hereby
empowered to exercise all such powers and do all such acts and things as may be
exercised or done by the Corporation.

                                       6
<PAGE>

B.        SPECIAL MEETINGS CALLED BY BOARD OF DIRECTORS OR SHAREHOLDERS

          Special Meetings of Shareholders of the Corporation may be called by
the Board of Directors pursuant to a resolution adopted by a majority of the
total number of authorized directors (whether or not there exist any vacancies
in previously authorized directorships at the time any such resolution is
presented to the Board for adoption) (the "Full Board"), or by the holders of
not less than fifty percent (50%) of all the votes entitled to be cast on any
issue at the proposed special meeting if such holders of stock sign, date and
deliver to the Corporation's Secretary one or more written demands for the
meeting describing the purpose or purposes for which the special meeting is to
be held.

                                  ARTICLE VI.
                                  -----------

                        Number of Directors; Vacancies

A.        NUMBER OF DIRECTORS AND COMPOSITION OF BOARD

          The initial number of directors of the Corporation shall be one (1).
The number of directors may be either increased or diminished from time to time
in the manner provided in the Bylaws, but shall never be less than one (1) nor
more than twenty-five (25).

B.        CLASSIFICATION OF BOARD

          The Board of Directors shall be and is divided into three classes,
Class I, Class II and Class III, with the number of directors in each class
being as nearly equal as possible.  Each director shall serve for a term ending
on the date of the third annual meeting following the annual meeting at which
such director was elected; provided, however, that the directors assigned to
                           --------  -------
Class I shall serve for a term ending on the date of the first annual meeting
next following May 31, 1999, the directors assigned to Class II shall serve for
a term ending on the date of the second annual meeting next following May 31,
1999, and the directors assigned to Class III shall serve for a term ending on
the date of the third annual meeting next following May 31, 1999.

          Any increase or decrease in the number of directors shall be so
apportioned among the classes as to make all classes as nearly equal in number
as possible.

          Notwithstanding any of the foregoing provisions of this Article, each
director shall serve until his successor is elected and qualified or until his
death, retirement, resignation or removal.  Should a vacancy occur or be
created, the remaining directors (even though less than a quorum) may fill the
vacancy for the full term of the class in which the vacancy occurs or is
created.

C.        VACANCIES

          A director shall hold office until the annual meeting of the
shareholders and until his successors shall be elected, subject, however, to the
director's prior death, resignation, retirement, disqualification or removal
from office.  Subject to the rights of the holders of any

                                       7
<PAGE>

series of Preferred Stock then outstanding, any vacancy on the Board of
Directors, howsoever resulting (including vacancies created as a result of a
resolution of the Board of Directors increasing the authorized number of
directors), may be filled by a majority of the directors then in office, even if
less than a quorum, or by a sole remaining director.

                                 ARTICLE VII.
                                 ------------

                                Indemnification

          Provided the person proposed to be indemnified satisfies the requisite
standard of conduct for permissive indemnification by a corporation as
specifically set forth in the applicable provisions of the Florida Business
Corporation Act (currently, Section 607.0850(7) of the Florida Statutes), as the
same may be amended from time to time, the Corporation shall indemnify its
officers and directors, and may indemnify its employees and agents, to the
fullest extent provided, authorized, permitted or not prohibited by the
provisions of the Florida Business Corporation Act and the Bylaws of the
Corporation, as the same may be amended and supplemented, from and against any
and all of the expenses or liabilities incurred in defending a civil or criminal
proceeding, or other matters referred to in or covered by said provisions,
including advancement of expenses prior to the final disposition of such
proceedings and amounts paid in settlement of such proceedings, both as to
action in his or her official capacity and as to action in another capacity
while an officer, director, employee or other agent.  The indemnification
provided for herein shall not be deemed exclusive of any other rights to which
those indemnified may be entitled under any bylaw, agreement, vote of
shareholders or Disinterested Directors or otherwise.  Such indemnification
shall continue as to a person who has ceased to be a director, officer, employee
or agent, and shall inure to the benefit of the heirs and personal
representatives of such a person.  Except as otherwise required by law, an
adjudication of liability shall not affect the right to indemnification for
those indemnified.

                                 ARTICLE VIII.
                                 -------------

                                   Amendment

          The Corporation reserves the right to amend or repeal any provision
contained in these Articles of Incorporation in the manner prescribed by the
laws of the State of Florida and all rights conferred upon shareholders are
granted subject to this reservation; provided, however, that, notwithstanding
any other provision of these Articles of Incorporation or any provision of law
which might otherwise permit a lesser vote or no vote, but in addition to any
votes of the holders of any class or series of the stock of this Corporation
required by law or by these  Articles of Incorporation, the affirmative vote of
the holders of at least two-thirds (66 2/3%) of the voting power of all of the
then outstanding shares of the capital stock of the Corporation entitled to vote
generally in the election of directors, voting together as a single class shall
be required to amend or repeal any of Articles V, VI, VII, and VIII.

                        AMENDED AND RESTATED BYLAWS OF
                        SBA COMMUNICATIONS CORPORATION

      As adopted by the Board of Directors on the 7th day of June 1999.

                                  ARTICLE I.
                           MEETINGS OF SHAREHOLDERS
                           ------------------------

     Section 1.  Annual Meeting.  The annual meeting of the shareholders of this
                 --------------
Corporation shall be held annually at the time and place designated by the Board
of Directors of the Corporation. Business transacted at the annual meeting shall
include the election of directors of the Corporation, in accordance with the
applicable provisions of the Articles of Incorporation, and all other duties and
powers conferred upon the shareholders by the laws of the State of Florida.

     Section 2.  Special Meetings. Special meetings of the shareholders shall be
                 ----------------
held when directed by the Board of Directors through a resolution adopted by a
majority of the total number of authorized directors (whether or not any
vacancies of previously authorized directorships exist at the time the Board is
presented with such resolution), or when requested in writing by the holders of
not less than fifty percent (50%) of all the shares entitled to vote on any
issue at the meeting. The call for the meeting shall be issued by the Secretary
or the shareholders requesting the special meeting, unless the President, the
Board of Directors or such shareholders designate another person to do so.

     Section 3.  Place.  Meetings of shareholders may be held within or outside
                 -----
of the State of Florida. If no place is designated in the notice for a meeting
of shareholders, the place of meeting shall be the principal office of the
Corporation.

     Section 4.  Notice.  Except as provided in the Florida Business Corporation
                 ------
Act (the "Act"), written notice stating the place, day and hour of the meeting,
and in the case of a special meeting, or as otherwise provided by law, the
purpose or purposes for which the meeting is called, shall be delivered to each
shareholder of record entitled to vote at such meeting. Such notice shall be
given at least ten (10) but not more than sixty (60) days before the date of the
meeting, by first class mail by the Secretary or, in the case of a special
meeting duly called by the shareholders, the shareholders requesting the special
meeting, unless the President, the Board of Directors or such shareholders
designate another person to do so. Such notice shall be mailed to each
shareholder at his or her address as it appears on the books of the Corporation.
If the notice is mailed at least thirty (30) days before the date of the
meeting, it may be done by a class of United States mail other than first class.
Such notice is deemed delivered when deposited in the United States mail with
postage prepaid thereon.

     Section 5.  Notice of Adjourned Meetings.  When a meeting is adjourned to
                 ----------------------------
another time or place, it shall not be necessary to give any notice of the
adjourned meeting if the time and place to which the meeting is adjourned are
announced at the meeting at which the adjournment is taken, and at the adjourned
meeting any business may be transacted that might have been
<PAGE>

transacted on the original date of the meeting. If, however, after the
adjournment the Board of Directors fixes a new record date for the adjourned
meeting, a notice of the adjourned meeting shall be given as provided in Article
I, Section 4 of these Bylaws to each shareholder of record on the new record
date entitled to vote at such meeting.

     Section 6.  Waiver of Notice of Shareholders Meetings.  Whenever any notice
                 -----------------------------------------
is required to be given to any shareholder, a waiver thereof in writing signed
by the shareholder or shareholders entitled to such notice, whether before,
during or after the time of the meeting stated therein and delivered to the
Corporation for inclusion in the minutes or filing with the corporate records,
shall be equivalent to the giving of such notice. Attendance by a shareholder at
a meeting shall constitute a waiver of: (a) lack of notice or defective notice
of such meeting, unless the shareholder at the beginning of the meeting objects
to holding the meeting; or (b) lack of defective notice of a particular matter
at a meeting that is not within the purpose or purposes described in the meeting
notice, unless the person objects to considering that particular matter when it
is presented. Unless otherwise required by the Articles of Incorporation,
neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the shareholders need be specified in any written waiver of
notice.

     Section 7.  Fixing Record Date.  For the purpose of determining
                 ------------------
shareholders entitled to notice of, or to vote at, any meeting of shareholders
or any adjournment thereof, or to demand a special meeting, or to receive
payment of any distribution, or in order to make a determination of shareholders
for any other purpose,  the Board of Directors may fix in advance a date as the
record date for any determination of shareholders, such date in any case to be
not more than seventy (70) days prior to the date on which the particular action
requiring such determination of shareholders is to be taken.  A determination of
shareholders entitled to notice of, or to vote at, any meeting of shareholders
shall apply to any adjournment thereof, unless the Board of Directors fixes a
new record date for the adjourned meeting, which it must do if the meeting is
adjourned to a date more than one hundred twenty (120) days after the date fixed
for the original meeting.

     Section 8.  Voting Record.  After fixing a record date for a meeting of
                 -------------
shareholders, the Corporation shall prepare an alphabetical list of the names of
all shareholders who are entitled to notice of such meeting, arranged by voting
group, with the address of, and the number and class and series, if any, of the
shares held by, each shareholder. The shareholders' list must be available for
inspection by any shareholder for a period of ten (10) days prior to the meeting
or such shorter time as exists between the record date and the meeting and
continuing through the meeting at the Corporation's principal office, at a place
identified in the meeting notice in the city where the meeting will be held, or
at the office of the Corporation's transfer agent or registrar. Any shareholder
of the Corporation or his agent or attorney is entitled on written demand to
inspect the shareholders' list (subject to the requirements of the Act), during
regular business hours and at the shareholder's expense, during the period it is
available for inspection. The Corporation shall make the shareholders' list
available at the meeting of shareholders, and any shareholder or his agent or
attorney is entitled to inspect the list at any time during the meeting or any
adjournment.

                                       2
<PAGE>

     If the requirements of this Section have not been substantially complied
with, the meeting shall be adjourned until such time as the Corporation complies
with such requirements on demand of any shareholder in person or by proxy who
failed to get such access. If no such demand is made, failure to comply with the
requirements of this Section shall not affect the validity of any action taken
at such meeting.

     Section 9.   Shareholder Quorum and Voting.  Shares entitled to vote as a
                  -----------------------------
separate voting group may take action on a matter at a meeting only if a
quorum of those shares exists with respect to that matter.  Except as otherwise
provided in the Articles of Incorporation or by the Act, a majority of the
shares entitled to vote on the matter by each voting group, represented in
person or by proxy, shall constitute a quorum at any meeting of shareholders,
but in no event shall a quorum consist of less than one-third of the shares of
each voting group entitled to vote.  If less than a majority of outstanding
shares entitled to vote are represented at a meeting, a majority of the shares
so represented may adjourn the meeting from time to time without further notice.
After a quorum has been established at any shareholders' meeting, the subsequent
withdrawal of shareholders, so as to reduce the number of shares entitled to
vote at the meeting below the number required for a quorum, shall not affect the
validity of any action taken at the meeting or any adjournment thereof.

     Once a share is represented for any purpose at a meeting, it is deemed
present for quorum purposes for the remainder of the meeting and for any
adjournment of that meeting, unless a new record date is or must be set for that
adjourned meeting.  When a specified item of business is required to be voted on
by a class or series of stock, a majority of the shares of such class or series
shall constitute a quorum for the transaction of such item of business by that
class or series.

     Section 10.  Votes Per Share.  Except as otherwise provided in the Articles
                  ---------------
of Incorporation, the terms of any outstanding Preferred Stock or by the Act,
each outstanding share, regardless of class, shall be entitled to one vote on
each matter submitted to a vote at a meeting of shareholders.

     Section 11.  Manner of Action.  If a quorum is present, action on a matter
                  ----------------
(other than the election of directors) by a voting group is approved if the
votes cast within the voting group favoring the action exceed the votes cast
opposing the action, unless a greater or lesser number of affirmative votes is
required by the Articles of Incorporation, the Bylaws or by law.

     Section 12.  Voting for Directors.  At each election for directors, every
                  --------------------
shareholder entitled to vote at such election shall have the right to vote, in
person or by proxy, the number of shares owned by him or her for as many persons
as there are directors to be elected at that time and for whose election he or
she has a right to vote. Unless otherwise and affirmatively provided for in the
Articles of Incorporation, cumulative voting is not authorized and the directors
shall be elected by a plurality of the votes cast by the shares entitled to vote
in such election at a meeting at which a quorum is present.

     Section 13.  Voting of Shares.  A shareholder may vote at any duly called
                  ----------------
and noticed meeting of shareholders of the Corporation, either in person or by
proxy.

                                       3
<PAGE>

     Shares standing in the name of another corporation, domestic or foreign,
may be voted by the officer, agent or proxy designated by the bylaws of the
corporate shareholder or, in the absence of any applicable bylaw, by such person
as the board of directors of the corporate shareholder may designate. Proof of
such designation may be made by presentation of a certified copy of the Bylaws
or other instrument of the corporate shareholder. In the absence of any such
designation or, in the case of conflicting designation by the corporate
shareholder, the chairman of the board, the president, any vice president, the
secretary and the treasurer of the corporate shareholder shall be presumed to
possess, in that order, authority to vote such shares.

     Shares held by an administrator, executor, guardian, personal
representative or conservator may be voted by him or her, either in person or by
proxy, without a transfer of such shares into his or her name. Shares standing
in the name of a trustee may be voted by him or her, either in person or by
proxy, but no trustee shall be entitled to vote shares held by him or her
without a transfer of such shares into his or her name or the name of his or her
nominee.

     Shares held by or under the control of a receiver, a trustee in bankruptcy
proceedings or an assignee for the benefit of creditors may be voted by such
person without the transfer thereof into his or her name.

     If a share or shares stand of record in the names of two or more persons,
whether as fiduciaries, members of a partnership, joint tenants, tenants in
common, tenants by the entirety or otherwise, or if two or more persons have the
same fiduciary relationship with respect to the same shares, unless the
Secretary of the Corporation is given notice to the contrary and is furnished
with a copy of the instrument or order appointing them or creating the
relationship wherein it is so provided, then acts with respect to voting shall
have the following effect: (a) if only one votes, in person or by proxy, that
act binds all; (b) if more than one votes, in person or by proxy, the act of the
majority so voting binds all; (c) if more than one votes, in person or by proxy,
but the vote is evenly split on any particular matter, each faction is entitled
to vote the share or shares in question proportionally; or (d) if the instrument
or order so filed shows that any such tenancy is held in unequal interest, a
majority or a vote evenly split for purposes hereof shall be a majority or a
vote evenly split in interest. The principles of this paragraph shall apply,
insofar as possible, to execution of proxies, waivers, consents, or objections
and for the purpose of ascertaining the presence of a quorum.

     Section 14.  Proxies.  Any shareholder of the Corporation, other person
                  -------
entitled to vote on behalf of a shareholder pursuant to the Act, or attorney-in-
fact for such persons, may vote the shareholder's shares in person or by proxy.
Any shareholder of the Corporation may appoint a proxy to vote or otherwise act
for him or her by signing an appointment form, either personally or by an
attorney-in-fact. An executed telegram or cablegram appearing to have been
transmitted by such person, or a photographic, photostatic, or equivalent
reproduction of an appointment form, shall be deemed a sufficient appointment
form.

     An appointment of a proxy is effective when received by the Secretary of
the Corporation or such other officer or agent which is authorized to tabulate
votes, and shall be valid for up to eleven (11) months, unless a longer period
is expressly provided in the appointment form.

                                       4
<PAGE>

     The death or incapacity of the shareholder appointing a proxy does not
affect the right of the Corporation to accept the proxy's authority unless
notice of the death or incapacity is received by the Secretary or other officer
or agent authorized to tabulate votes before the proxy exercises his authority
under the appointment.

     An appointment of a proxy is revocable by the shareholder unless the
appointment form conspicuously states that it is irrevocable and the appointment
is coupled with an interest.

     Section 15.  Voting Trusts.  One or more shareholders may create a voting
                  -------------
trust, conferring on a trustee the right to vote or otherwise act for them, by
signing an agreement setting out the provisions of the trust and transferring
their shares to the trustee. When a voting trust agreement is signed, the
trustee shall prepare a list of the names and addresses of all owners of
beneficial interest in the trust, together with the number and class of shares
each transferred to the trust, and deliver copies of the list and agreement to
the Corporation's principal office. After filing a copy of the list and
agreement in the Corporation's principal office, such copies shall be open to
inspection by any shareholder of the Corporation, subject to the requirements of
the Act, or to any beneficiary of the trust under the agreement during business
hours. The trustee must also deliver a copy of each extension of the voting
trust agreement, and a list of beneficial owners under such extended agreement,
to the Corporation's principal office.

     Section 16.  Shareholders' Agreements.  Two or more shareholders may
                  ------------------------
provide for the manner in which they will vote their shares, and providing for
such other matters as are permitted by the Act, by signing an agreement for that
purpose.  When a shareholders' agreement is signed, the shareholders who are
parties thereto shall deliver copies of the agreement to the Corporation's
principal office.  After filing a copy of the agreement in the Corporation's
principal office, such copies shall be open to inspection by any shareholder of
the Corporation, subject to the requirements of the Act, or any party to the
agreement during business hours.

     Section 17.  Inspectors of Election. Prior to each meeting of shareholders,
                  ----------------------
the Board of Directors or the President may appoint one or more Inspectors of
Election. Upon his appointment, each such Inspector shall take and sign an oath
to faithfully execute the duties of Inspector at such meeting with strict
impartiality and to the best of his ability. Such Inspector(s) shall determine
the number of shares outstanding, the number of shares present at the meeting
and whether a quorum is present at such meeting. The Inspector(s) shall receive
votes and ballots and shall determine all challenges and questions as to the
right to vote and shall thereafter count and tabulate all votes and ballots and
determine the result. Such Inspector(s) shall do such further acts as are proper
to conduct the elections of directors and the vote on other matters with
fairness to all shareholders. The Inspector(s) shall make a certificate of the
results of the elections of directors and the vote on other matters. No
Inspector shall be a candidate for election as a director of the Corporation.

     Section 18.  Action by Shareholders Without a Meeting.  Unless otherwise
                  ----------------------------------------
provided in the articles of incorporation, action required or permitted to be
taken at any meeting of the shareholders may be taken without a meeting, without
prior notice and without a vote if the action is taken by the holders of
outstanding shares of each voting group entitled to vote thereon

                                       5
<PAGE>

having not less than the minimum number of votes with respect to each voting
group that would be necessary to authorize or take such action at a meeting at
which all voting groups and shares entitled to vote thereon were present and
voted.  In order to be effective, the action must be evidenced by one or more
written consents describing the action taken, dated and signed by approving
shareholders having the requisite number of votes of each voting group entitled
to vote thereon, and delivered to the corporation by delivery to its principal
office in Florida, its principal place of business, the Secretary of the
corporation, or another office or agent of the corporation having custody of the
book in which proceedings of meetings of shareholders are recorded.  No written
consent shall be effective to take such corporate action unless, within sixty
(60) days of the date of the earliest dated consent delivered in the manner
required by this Section, written consents signed by the number of holders
required to take such action are delivered to the corporation as set forth in
this Section.

     Any written consent may be revoked prior to the date that the corporation
receives the required number of consents to authorize the proposed action. No
revocation is effective unless in writing and until received by the corporation
at its principal office in Florida or its principal place of business, or
received by the Secretary or other officer or agent of the corporation having
custody of the book in which proceedings of meetings of shareholders are
recorded.

     Within ten (10) days after obtaining such authorization by written consent,
notice shall be given to those shareholders who have not consented in writing or
who are not entitled to vote on the action. The notice shall fairly summarize
the material features of the authorized action and, if the action is one for
which dissenters' rights are provided under the articles of incorporation or by
law, the notice shall contain a clear statement of the right of shareholders
dissenting therefrom to be paid the fair value of their shares upon compliance
with applicable law.

     A consent signed as required in this Section has the effect of a meeting
vote and may be described as such in any document.

     Whenever action is taken as set forth in this Section, the written consent
of the shareholders consenting thereto or the written reports of inspectors
appointed to tabulate such consents shall be filed with the minutes of
proceedings of shareholders.

     Section 19.  Notifications of Nominations and Proposed Business.
                  --------------------------------------------------

     (a) General. Subject to the rights of holders of any class or series
         -------
of stock having a preference over the Common Stock as to dividends or upon
liquidation,

          (i)   nominations for the election of directors, and

          (ii)  business proposed to be brought before any shareholder meeting

may be made by the Board of Directors or proxy committee appointed by the Board
of Directors or by any shareholder entitled to vote in the election of directors
generally.  However, any such shareholder may nominate one or more persons for
election as directors at a meeting or propose business to be brought before a
meeting, or both, only if such shareholder has given timely notice

                                       6
<PAGE>

in proper written form of his intent to make such nomination or nominations or
to propose such business. To be timely, a shareholder's notice must be delivered
to or mailed and received by the Secretary of the Corporation as set forth in
paragraph (b) with respect to an annual meeting or as set forth in paragraph (c)
with respect to a special meeting. To be in proper written form, a shareholder's
notice to the Secretary shall set forth:

          (i)   the name and address of the shareholder who intends to make the
          nominations or propose the business and, as the case may be, of the
          person or persons to be nominated or of the business to be proposed;

          (ii)  a representation that the shareholder is a holder of record of
          stock of the Corporation entitled to vote at such meeting and, if
          applicable, intends to appear in person or by proxy at the meeting to
          nominate the person or persons specified in the notice;

          (iii) a representation as to whether the shareholder or the beneficial
          owner, if any, intends or is part of  a group which intends to (a)
          deliver a proxy statement and/or form of proxy to holders of at least
          the percentage of the Corporation's outstanding stock required to
          approve or adopt the proposal or elect the nominee and/or (b)
          otherwise solicit proxies from shareholders in support of such
          proposal or nomination;

          (iv)  if applicable, a description of all arrangements or
          understandings between the shareholder and each nominee and any other
          person or persons (naming such person or persons) pursuant to which
          the nomination or nominations are to be made by the shareholder;

          (v)   such other information regarding each nominee or each matter of
          business to be proposed by such shareholder as would be required to be
          included in a proxy statement filed pursuant to the proxy rules of the
          Securities and Exchange Commission had the nominee been nominated, or
          intended to be nominated or the matter been proposed or intended to be
          proposed by the Board of Directors; and

          (vi)  if applicable, the consent of each nominee to serve as director
          of the corporation if so elected.

     (b) Annual Meetings.  For nominations or other business to be properly
         ---------------
brought before an annual meeting by a shareholder pursuant to this Section 19,
the shareholder must have given timely notice thereof in writing to the
Secretary of the Corporation and such other business must otherwise be a proper
matter for shareholder action.  To be timely, a shareholder's notice shall be
delivered to the Secretary at the principal executive offices of the Corporation
not later than the close of business on the one hundred twentieth day nor
earlier than the close of business on the one hundred fiftieth day prior to the
date of the Corporation's proxy statement released to shareholders in connection
with the preceding year's annual meeting (provided, however, that in the event
that the date of the annual meeting is more than thirty days before or more than
seventy days after the first anniversary of the preceding year's annual meeting,
notice by the shareholder

                                       7
<PAGE>

must be so delivered not earlier than the close of business on the one hundred
fiftieth day prior to such annual meeting and not later than the close of
business on the later of the one hundred twentieth day prior to such annual
meeting or the tenth day following the day on which public announcement of the
date of such meeting is first made by the Corporation). In no event shall the
public announcement of an adjournment or postponement of an annual meeting
commence a new time period (or extend any time period) for the giving of a
shareholder's notice as described above. Notwithstanding anything in the second
sentence of this paragraph (b) to the contrary, in the event that the number of
directors to be elected to the Board of Directors of the Corporation at an
annual meeting is increased and there is no public announcement by the
Corporation naming all of the nominees for director or specifying the size of
the increased Board of Directors at least one hundred thirty days prior to the
date of the Corporation's proxy statement released to shareholders in connection
with the preceding year's annual meeting, a shareholder's notice required by
this Section 19 shall also be considered timely, but only with respect to
nominees for any new positions created by such increase, if it shall be
delivered to the Secretary at the principal executive offices of the Corporation
not later than the close of business on the tenth day following the day on which
such public announcement is first made by the Corporation.

     (c) Special Meetings. Only such business shall be conducted at a special
         ----------------
meeting of shareholders as shall have been brought before the meeting pursuant
to the Corporation's notice of meeting. Nominations of persons for election to
the Board of Directors may be made at a special meeting of shareholders at which
directors are to be elected pursuant to the Corporation's notice of meeting (1)
by or at the direction of the Board of Directors or (2) provided that the Board
of Directors has determined that directors shall be elected at such meeting, by
any shareholder of the Corporation who is a shareholder of record at the time
the notice provided for in this Section 19 is delivered to the Secretary of the
Corporation, who shall be entitled to vote at the meeting and upon such election
and who complies with the notice procedures set forth in this Section 19. In the
event the Corporation calls a special meeting of shareholders for the purpose of
electing one or more directors to the Board of Directors, any such shareholder
entitled to vote in such election of directors may nominate a person or persons
(as the case may be) for election to such position(s) as specified in the
Corporation's notice of meeting, if the shareholder's notice required by
paragraph (a) of this Section 19 shall be delivered to the Secretary at the
principal executive offices of the Corporation not earlier than the close of
business on the one hundred fiftieth day prior to such special meeting and not
later than the close of business on the one hundred twentieth day prior to such
special meeting, or the tenth day following the day on which public announcement
is first made of the date of the special meeting and of the nominees proposed by
the Board of Directors to be elected at such meeting. In no event shall the
public announcement of an adjournment or postponement of a special meeting
commence a new time period (or extend any time period) for the giving of a
shareholder's notice as described above.

     (d) Public Announcement.  For purposes of this Section 19, "public
         -------------------
announcement" shall mean disclosure in a press release reported by  Business
Wire, the Dow Jones News Service, Associated Press or comparable national news
service or in a document publicly filed by the Corporation with the Securities
and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Securities
Exchange Act (the "Exchange Act").

                                       8
<PAGE>

     (e) Exchange Act Compliance. Notwithstanding the foregoing provisions
         -----------------------
of this Section 19, a shareholder shall also comply with all applicable
requirements of the Exchange Act and the rules and regulations promulgated
thereunder with respect to the matters set forth in this Section 19.  Nothing in
this Section 19 shall be deemed to affect any rights (i) of stockholders to
request inclusion of proposals in the Corporation's proxy statement pursuant to
Rule 14a-8 under the Exchange Act or (ii) of the holders of any series of
Preferred Stock to elect directors under specified circumstances.

     The chairman of the meeting may refuse to acknowledge the nomination of any
person or the proposal of any business not made in compliance with the foregoing
procedure.

                                  ARTICLE II.

                                   DIRECTORS
                                   ---------

     Section 1.  Functions.  Except as provided in the Articles of Incorporation
                 ---------

                 ------

from time to time; provided, however, that the Board of Directors shall not
consist of less than one (1) person, and not more than twenty-five (25) persons.

     Section 3.  How Selected.  Unless appointed to fill a vacancy, directors
                 ------------

from time to time.

     Section 4.  Qualifications. Directors must be natural persons over the age
                 --------------
of 18 years old, but need not be residents of the State of Florida or
shareholders of this Corporation.

     Section 5.  Resignation.  Any director may resign at any time by delivering
                 -----------
written notice to the Corporation, the Board of Directors or its Chairman. Such
resignation is effective when the notice is delivered unless the notice
specifies a later effective date, in which event the Board of Directors may fill
the pending vacancy before the effective date if the Board of Directors provides
that the successor does not take office until the effective date.

     Section 6.  Vacancies.  A director shall hold office until the annual
                 ---------
meeting of the shareholders and until his successors shall be elected and shall
qualify, subject, however, to the director's prior death, resignation,
retirement, disqualification, or removal from office.  Any vacancy occurring in
the Board of Directors, including any vacancy created by reason of an increase
in the number of directors, may be filled by the affirmative vote of a majority
of the remaining directors though less than a quorum of the Board of Directors,
or by the sole remaining director.

     Section 7.  Regular Meetings.  An annual regular meeting of the Board of
                 ----------------
Directors shall be held without notice as soon as practicable after the annual
meeting of shareholders for

                                       9
<PAGE>

the purpose of the election of officers and the transaction of such other
business as may come before the meeting, and at such other time and place as may
be determined by the Board of Directors. The Board of Directors may, with or
without notice, at any time and from time to time, decide the time and place,
either within or outside of the State of Florida, for the holding of the annual
regular meeting or additional regular meetings of the Board of Directors.
Meetings of the Board of Directors may be called by the Chairman of the Board,
the President of the Corporation, or a majority of the Board of Directors.

     Section 8.  Special Meetings.  Special meetings of the Board of Directors
                 ----------------
may be called by the Chairman of the Board, the President of the Corporation, or
a majority of the Board of Directors.

     The person or persons authorized to call special meetings of the Board of
Directors may designate any place, either within or outside of the State of
Florida, as the place for holding any special meeting of the Board of Directors
called by them. If no designation is made, the place of meeting shall be the
principal office of the Corporation in the State of Florida.

     Notice of any special meeting of the Board of Directors may be given by any
reasonable means, whether oral or written, and at any reasonable time prior to
such meeting. The reasonableness of any notice given in connection with any
special meeting of the Board of Directors shall be determined in light of all of
the pertinent circumstances. It shall be presumed that notice of any special
meeting given at least two (2) days prior to such special meeting, either orally
(by telephone or in person), or by written notice delivered personally or mailed
to each director at his or her business or residence address, is reasonable. If
mailed, such notice of any special meeting shall be deemed to be delivered on
the second day after it is deposited in the United States mail, so addressed,
with postage thereon prepaid. If notice is given by electronic transmission,
such notice shall be deemed to be delivered when the notice is delivered by the
electronic device. Neither the business to be transacted at, nor the purpose or
purposes of, any special meetings of the Board of Directors need be specified in
the notice or in any written waiver of notice of such meeting.

     Section 9.  Waiver of Notice of Meeting.  Notice of a meeting of the Board
                 ---------------------------
of Directors need not be given to any director who signs a written waiver of
notice either before, during or after the meeting. Attendance of a director at a
meeting shall constitute a waiver of notice of such meeting and waiver of any
and all objections to the place of the meeting, the time of the meeting and the
manner in which it has been called or convened, except when a director states,
at the beginning of the meeting or promptly upon arrival at the meeting, any
objection to the transaction of business because the meeting is not lawfully
called or convened.

     Section 10.  Quorum and Voting.  A majority of the number of directors
                  -----------------
fixed in the manner provided by these Bylaws shall constitute a quorum for the
transaction of business; provided, however, that whenever, for any reason, a
vacancy occurs in the Board of Directors, a quorum shall consist of a majority
of the remaining directors until the vacancy has been filled. The act of the
majority of the directors present at a meeting at which a quorum is present when
the vote is taken shall be the act of the Board of Directors.

                                       10
<PAGE>

     A majority of the directors present, whether or not a quorum exists, may
adjourn any meeting of the Board of Directors to another time and place. Notice
of any such adjourned meeting shall be given to the directors who were not
present at the time of the adjournment and, unless the time and place of the
adjourned meeting are announced at the time of the adjournment, to the other
directors.

     Section 11.  Presumption of Assent.  A director of this Corporation who is
                  ---------------------
present at a meeting of its Board of Directors, or a committee of the Board of
Directors, at which action on any corporate matter is taken shall be presumed to
have assented to the action taken, unless he or she (i) objects at the beginning
of the meeting (or promptly upon his or her arrival) to holding the meeting or
transacting specified business at the meeting, or (ii) votes against such action
or abstains from the action taken; or (iii) has his or her dissent entered into
the minutes of the meeting or filed with the person acting as the secretary of
the meeting before the adjournment thereof or immediately thereafter, unless the
dissenting director voted in favor of such action.

                  -----------------------------------------------------------
Telephone or Similar Communications.  Members of the Board of Directors may
- -----------------------------------
participate in a meeting of such Board by means of a conference telephone or
similar communications equipment if all persons participating in the meeting can
hear each other at the same time. Participation by such means shall constitute
presence in person at a meeting.

     Section 13.  Action Without a Meeting.  Any action required or permitted
                  ------------------------
to be taken at a meeting of the Board of Directors or a committee thereof may be
taken without a meeting if a consent in writing, setting forth the action so
taken, is signed by all of the directors of this Corporation, or all the members
of the committee, as the case may be. Action taken under this Section is
effective when the last director or member of the committee signs the consent,
unless the consent specifies a different effective date. Such consent shall have
the effect as a meeting vote and may be described as such in any document.

     Section 14.  Compensation.  Each director may be paid his expenses, if any,
                  ------------
of attendance at each meeting of the Board of Directors and a committee thereof,
and may be paid a stated salary as a director or a fixed sum for attendance at
each meeting of the Board of Directors (or a committee thereof) or both, as may
from time to time be determined by action of the Board of Directors. No such
payment shall preclude any director from serving the Corporation in any other
capacity and receiving compensation therefor.

     Section 15.  Director Conflicts of Interests.  No contract or other
                  -------------------------------
transaction between this Corporation and one or more of its directors or any
other corporation, firm, association or entity in which one or more of the
directors of this Corporation are directors or officers or are financially
interested shall be either void or voidable because of such relationship or
interest, or because such director or directors of this Corporation are present
at the meeting of the Board of Directors or a committee thereof which
authorizes, approves or ratifies such contract or transaction, or because his or
their vote(s) are counted for such purpose, if:

             (a) The fact of such relationship or interest is disclosed or known
to the Board of Directors or committee which authorizes, approves or ratifies
the contract or transaction by a

                                       11
<PAGE>

vote or consent sufficient for the purpose without counting the vote(s) or
written consent(s) of such interested director(s); or

          (b) The fact of such relationship or interest is disclosed or known to
the shareholders entitled to vote and they authorize, approve or ratify such
contract or transaction by vote taken at an annual or special meeting of
shareholders; or

          (c) The contract or transaction is fair and reasonable as to the
Corporation at the time it is authorized by the Board of Directors, a committee
thereof or the shareholders.

          Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the Board of Directors or a committee
thereof which authorizes, approves or ratifies such contract or transaction.

                                 ARTICLE III.

terminated at any time by affirmative action of the Board.

          Section 3.  Meetings.  Each committee shall hold as many meetings as
                      --------
are necessary to continue or complete the performance of its duties.

          Section 4.  Record of Meetings.  Each committee shall keep or cause to
                      ------------------
be kept minutes of each meeting held, and each set of minutes shall include a

                                  ARTICLE IV.

                                   OFFICERS
                                   --------

          Section 1.  Officers.  If so appointed by the Board of Directors, the
                      --------

<PAGE>

Corporation in his capacity as an officer of the Corporation, designate in which

     Section 1.  Certificates for Shares.  The Board of Directors shall
                 -----------------------

of shares or different series within a class are authorized, a summary of the
designation, relative rights, preferences, and limitations applicable to each
class and the variations in rights, preferences, and limitations determined for
each series (and the authority of the Board of Directors to determine variations
for future series), or in the alternative, that the Corporation will provide the

issued in consecutive order, and on the face of each share shall be entered the
name of the person owning the shares represented by the certificate, the number
of shares represented by the certificate, and the date of issuance of the
certificate.  Upon issuance, the certificate shall be signed by the President or
a Vice President, and countersigned by the Secretary or an assistant secretary,

books of the Corporation, and only after the surrender to the Corporation of the
certificates representing such shares, if any, by the person in whose name the
shares stand on the books of the Corporation, or his duly authorized legal
representative.  In all cases of transfer, the former certificate must be
surrendered and canceled before a new certificate will be issued.  In case of
transfer by an attorney-in-fact, the power of attorney, duly executed and
acknowledged, shall be deposited with the Secretary of the Corporation.

          Section 4.   Lost, Stolen or Destroyed Certificates.  The Corporation
                       --------------------------------------

form that it has been lost, destroyed or wrongfully taken; (b) requests the

certificate has been acquired by a purchaser for value in good faith and without
notice of any adverse claim; (c) at the discretion of the Board of Directors,
gives bond in such form and amount as the Corporation may require, to indemnify
the Corporation, the transfer agent and registrar against any claim that may be
made on account of the alleged loss, destruction or theft of such certificate;
and (d) satisfies any other reasonable requirements imposed by the Corporation.

                                   ---------

          Section 1.  Declaration.  The Board of Directors may by resolution or
                      -----------
vote declare such dividends as are permitted pursuant to Florida law, and which
are not otherwise prohibited by any other applicable law or regulation, whenever
in their opinion the condition of the Corporation's affairs will render it
expedient for such dividends to be declared; provided, however that no such
dividends shall be declared when the Corporation is insolvent, when such payment
would render the Corporation insolvent, or when the declaration or payment
thereof

                                       16
<PAGE>

would be contrary to applicable laws or regulations or to any restrictions
contained in the Articles of Incorporation.

          Section 2.  Types.  The following types of dividends may be declared
                      -----
from time to time by the Board of Directors:

such dividends may be paid only out of the unreserved and unrestricted earned
surplus of the Corporation.

                 (b)  Dividends in cash paid for out of current net profits or
retained earnings in accordance with the provisions of Florida Statutes, or any
successor statute.

                 (c)  Dividends paid in the Corporation's own authorized but
unissued shares out of any unreserved and unrestricted surplus of the
Corporation upon the following conditions:

                      (1) If the dividend is payable in its own shares having a
par value, such shares shall be issued at not less than the par value, and there
shall be transferred to stated capital at the time such dividend is paid an
amount of surplus equal to the aggregate par value of the shares to be issued as
a dividend;

                      (2) If a dividend is payable in its own shares without par
value, such shares shall be issued at such stated value as shall be fixed by the
Board of Directors by a resolution adopted at the time such dividend is
declared, and there shall be transferred to stated capital at the time such
dividend is paid an amount of surplus equal to the aggregate stated value so
fixed in respect to such shares, and the amount per share so transferred to
stated capital shall be disclosed to the shareholders receiving such dividend
concurrently with the payment thereof.

                 (d)  No dividend payable in shares of any class shall be paid
to the holders of the shares of any other class unless the Articles of
Incorporation so provide, or such payment is authorized by the affirmative vote
or the written consent of the holders of at least a majority of the outstanding
shares of the class in which the payment is to be made.

                                 ARTICLE VIII.

         INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS
         ------------------------------------------------------------

          Section 1.  Insurance.  The Board of Directors of the Corporation, in
                      ---------
its discretion, shall have authority on behalf of the Corporation to purchase
and maintain insurance on behalf of any person who is or was a director,
officer, employee, or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, partner, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the Corporation
would have the power to indemnify him against such liability under the
provisions of this Article.  The provisions of the following sections of this
Article VIII shall apply only in the event that no such insurance is in effect
or, if such insurance is in effect, only to the extent that matters for which
indemnification by the Corporation is permitted by such sections are not within
the coverage of such insurance.

          Section 2.  Action Against a Party Because of Corporation Position.
                      ------------------------------------------------------
The Corporation shall indemnify each officer or director, and may indemnify, in
its sole discretion, any employee or agent who was or is a party, or is
threatened to be made a party, to any threatened, pending, or completed claim,
action, suit, or proceeding, whether civil, criminal, administrative, or
investigative (other than an action by, or in the right of, the Corporation) by
reason of the fact that he or she is or was a director, officer, employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, partner, officer, employee, or agent of another corporation, a
partnership, joint venture, trust, or other enterprise against expenses
(including attorneys' fees), judgments, fines, and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit or
proceeding, including any appeal thereof, if he or she acted in good faith and
in a manner he reasonably believed to be in, or not opposed to, the best
interests of the Corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination of any claim, action, suit or proceeding by judgment, order,
settlement or conviction, or upon a plea of nolo contendere or its equivalent
shall not, of itself, create a presumption that such person did not act in good
faith and in a manner which he reasonably believed to be in, or not opposed to,
the best interests of the Corporation or, with respect to any criminal action or
proceeding, had reasonable cause to believe that his or her conduct was
unlawful.

          Section 3.  Action by or in the Right of Corporation.  The Corporation
                      ----------------------------------------
shall indemnify any officer or director, and may indemnify, at its sole
discretion, any employee or agent who was or is a party, or is threatened to be
made a party, to any threatened, pending, or completed claim, action or suit by
or in the right of the Corporation to procure a judgment in its favor by reason
of the fact that he or she is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, partner, officer, employee, or agent of another corporation,
partnership, joint venture, trust, or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him or her in
connection with the defense or settlement of such claim, action, or suit,
including any appeal thereof, if he or she acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made in respect of any
claim, issue, or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his or her duty to the
Corporation unless, and only to the extent that, the court in which such claim,
action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
such court shall deem proper.

          Section 4.  Reimbursement if Successful.  To the extent that the
                      ---------------------------
director, officer, employee, or agent of the Corporation has been successful on
the merits or otherwise in defense of any claim, action, suit, or proceeding
referred to in Section 2 or Section 3 of this Article VIII, or in defense of any
claim, issue, or matter therein, he or she shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith, notwithstanding that he had not been successful (on the
merits or otherwise) on any other claim, issue, or matter in any such claim,
action, suit or proceeding.

                      -------------
Section 3 of this Article VIII (unless ordered by a court of competent
jurisdiction) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he or she met
the applicable standard of conduct set forth in Section 2 or Section 3 of this
Article VIII.  Such determination shall be made:

                 (a)  By a majority vote of a quorum of the Board of Directors;
however, for the purposes of this Subsection, a quorum shall consist of
directors who are or were not parties to such action, suit or proceeding; or

                 (b)  If such quorum is not obtainable, or even if obtainable,
by a majority vote of a committee duly designated by the Board of Directors (in
which directors who are parties may participate) consisting solely of two or
more directors who were not at the time parties to the proceeding;

                 (c)  By independent legal counsel who are (i) selected by the
Board of Directors prescribed in paragraph (a) or the committee prescribed in
paragraph (b); or (ii) if a quorum of the directors cannot be obtained for
paragraph (a) and the committee cannot be designated under paragraph (b),
selected by majority vote of the full Board of Directors (in which directors who
are parties may participate);

                 (d)  By the shareholders by a majority vote of a quorum
consisting of shareholders who are or were not parties to such action, suit or
proceeding, or, if no such quorum is obtainable, by a majority vote of
shareholders who were not parties to such action, suit or proceeding.

          Section 6.  Advance Reimbursement.  Expenses, including attorneys'
                      ---------------------
fees, incurred in defending a civil or criminal action, suit, or proceeding
shall be paid to officers and directors, and, in its sole discretion, may be
paid to agents and employees by the Corporation in advance of the final
disposition of such action, suit or proceeding, upon a preliminary
determination, following one of the procedures set forth in Section 5 of this
Article VIII, that the director, officer, employee or agent met the applicable
standard of conduct set forth in Section 2 or Section 3 of this Article VIII, or
as authorized by the Board of Directors in the specific case and, in either
event, upon receipt of an undertaking by or on behalf of the director, officer,
employee or agent to repay such amount unless it shall ultimately be determined
that he is entitled to be indemnified by the Corporation as authorized in this
Article.

          Section 7.  Further Indemnification.  Indemnification as provided in
                      -----------------------
this Article shall not be deemed exclusive.  The Corporation shall make any
other further indemnification of any of its directors, officers, employees or
agents that may be authorized under any statute, rule or law, provision of
Articles of Incorporation, agreement, vote of shareholders or disinterested
directors, or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, except an indemnification
against gross negligence or willful misconduct.  Where such other provision
provides broader rights of indemnification than these Bylaws, such other
provision shall control.

director, officer, employee, or agent, and shall inure to the benefit of the
heirs, executors, and administrators of such a person.

accurate accounting records and shall keep records of minutes of all meetings of
its shareholders and Board of Directors, a record of all actions taken by the
Board of Directors without a meeting and a record of all actions taken by a

                        SBA COMMUNICATIONS CORPORATION

     RESOLVED, that on June 7, 1999, the Board of Directors and shareholders of
the Corporation desired that the preferences and relative, participating,
optional or other special rights, and the qualifications, limitations or
restrictions of the 4% Series A Convertible Preferred Stock, $.01 par value per
share, consisting of 8,050,000 shares issued and authorized (the "Series A
Preferred Stock"), the 4% Series B Redeemable Preferred Stock, $.01 par value
per share, consisting of 8,050,000 shares authorized, no shares issued (the
"Series B Preferred Stock"), the 4% Series C Convertible Preferred Stock, par
value $.01 per share, consisting of up to 4,472,272 shares authorized, no shares
issued (the "Series C Preferred Stock"), and the 4% Series D Redeemable
Preferred Stock, par value $.01 per share, consisting of up to 4,472,272 shares
authorized, no shares issued (the "Series D Preferred Stock"), shall be amended
and restated as set forth in this Second Amended and Restated Statement of
Designation, Preferences, Rights and Limitations, as follows:

             A.  4% SERIES A CONVERTIBLE PREFERRED STOCK
                 ---------------------------------------

1.   Dividends.
     ---------

     (a)  The holders of outstanding shares of Series A Preferred Stock shall be
entitled, in preference to the holders of any and all other classes of capital
stock of the Corporation (other than the Series B Preferred Stock, the Series C
Preferred Stock, and the Series D Preferred Stock, which will rank equally with
the Series A Preferred Stock as to dividends), to receive, out of any funds
legally available therefor, cumulative dividends on the Series A Preferred Stock
in cash, at the rate per annum of four percent (4%) of the Series A Base
Liquidation Amount (as defined in Section A.2 below), subject to proration for
partial years on the basis of a 365-day year ("Series A Cumulative Preference
Dividends"). Such dividends will accumulate commencing as of the date of
issuance of the Series A Preferred Stock and will be cumulative, to the extent
unpaid, whether or not they have been declared and whether or not there are
profits, surplus or other funds of the Corporation legally available for the
payment of dividends. Accrued but unpaid dividends on the Series A Preferred
Stock shall be payable upon conversion of the Series A Preferred Stock into
Class A Common Stock and Series B Preferred Stock. Dividends paid in cash in an
amount less than the total amount of such dividends at the time accumulated and
payable on all outstanding shares of Series A Preferred Stock, including
fractions, shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. At
<PAGE>

any time when shares of Series A Preferred Stock are outstanding and the Series
A Cumulative Preference Dividends have not been paid in full in cash: (i) no
dividend whatsoever shall be paid or declared, and no distribution shall be
made, on any capital stock of the Corporation ranking junior to the Series A
Preferred Stock; and no shares of capital stock of the Corporation ranking
junior to the Series A Preferred Stock shall be purchased, redeemed or acquired
by the Corporation and no monies shall be paid into or set aside or made
available for a sinking fund for the purchase, redemption or acquisition
thereof. All numbers relating to the calculation of dividends pursuant to this
Section A.1(a) shall be subject to equitable adjustment in the event of any
stock split, combination, reorganization, recapitalization, reclassification or
other similar event involving a change in the Series A Preferred Stock. At the
time of the fifth anniversary following the initial sale of the Series A
Preferred Stock, the dividend rate on the Series A Preferred Stock shall
increase to 8% of the Series A Base Liquidation Amount per annum. On the sixth
anniversary date, the dividend rate on the Series A Preferred Stock shall
increase to 14% of the Series A Base Liquidation Amount per annum.

     (b)  Notwithstanding the foregoing, while any of the Corporation's Senior
Discount Notes Due 2008, or any refinancing thereof (the "Senior Notes") remain
outstanding, the Corporation shall not be permitted to pay any cash dividends
upon the Series A Preferred Stock (including any such dividends payable in
connection with a conversion of the Series A Preferred Stock) and the holders of
the Series A Preferred Stock shall not be entitled to receive any such
dividends, if and to the extent that such dividends would be prohibited by any
term or provision of the indenture governing the Senior Notes issued by the
Corporation on or prior to April 1, 1998, as the same is in effect on the date
of original issuance of the Senior Notes and as may be amended, supplemented or
modified from time to time (the "Indenture"), or any documents relating to any
refinancing of the Senior Notes; provided that the covenant under the caption
"Restricted Payments" in the Indenture, or any documents relating to any
refinancing of the Senior Notes, will not be materially more restrictive with
regard to payments than the restrictions set forth in the covenant under the
caption "Certain Covenants--Restricted Payments" set forth in the Company's
final Offering Memorandum, dated February 25, 1998 (the "Referenced Document"),
and provided further that no such amendment, supplement or modification of the
Indenture, or any documents relating to any refinancing of the Senior Notes,
shall (i) increase the aggregate principal amount of Senior Notes outstanding,
(ii) be materially more restrictive with regard to payments than the
restrictions set forth in the covenant under the caption "Certain Covenants--
Restricted Payments" in the Referenced Document or (iii) extend the maturity of
the Senior Notes. Any change that will prohibit a payment that would otherwise
be permitted pursuant to the Referenced Document will be deemed material.

2.   Liquidation Preferences.
     -----------------------

     (a)  In the event of any distribution of assets upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, including
by consolidation, merger, share exchange or sale of all or substantially all of
the assets of the Corporation (in each case, an "Event of Dissolution"), each
holder of outstanding shares of Series A Preferred Stock shall be entitled to be
paid out of the assets of the Corporation available for distribution to
stockholders, whether such assets are capital, surplus, or earnings, and before
any amount shall be paid or

                                       2
<PAGE>

distributed to the holders of Class A Common Stock or Class B Common Stock or of
any other stock ranking on liquidation junior to the Series A Preferred Stock
(other than the Series B Preferred Stock, the Series C Preferred Stock, and the
Series D Preferred Stock, which will rank equally with the Series A Preferred
Stock in an Event of Dissolution) an amount in cash equal to the greater of (i)
the sum of (a) $3.726708075 per share (adjusted appropriately for stock splits,
stock dividends, recapitalizations and the like with respect to the Series A
Preferred Stock), plus (b) any accumulated but unpaid dividends to which such
holder of outstanding shares of Series A Preferred Stock is entitled pursuant to
Section A.1 hereof (the sum of (a) and (b) being referred to as the "Series A
Base Liquidation Amount") or (ii) the amount per share of Series A Preferred
Stock which the holders thereof would have received if all such shares had been
converted to Class A Common Stock and Series B Preferred Stock pursuant to
Sections A.5, A.6 or A.7 hereof immediately prior to such Event of Dissolution,
less any amount previously distributed on such shares in connection with such
Event of Dissolution; provided, however, that if, upon any Event of Dissolution,
                      --------  -------
the amounts payable with respect to the Series A Preferred Stock are not paid in
full, the holders of the Series A Preferred Stock shall share ratably in any
distribution of assets in proportion to the full respective preferential amounts
to which they are entitled.

     (b)  After full payment shall have been made to the holders of shares of
the Series A Preferred Stock (and Series B Preferred Stock, Series C Preferred
Stock and Series D Preferred Stock in accordance with Sections B.2, C.2 and D.2,
respectively), any balance of the assets of the Corporation then remaining shall
be allocated to the holders of shares of other classes of stock ranking junior
to the Series A Preferred Stock, including the holders of Class A Common Stock
and Class B Common Stock, in accordance with the respective interests therein.

3.   Voting Rights.
     -------------

     (a)  Except as otherwise expressly provided in these Amended and Restated
Articles of Incorporation, or as required by the Florida Business Corporation
Act (the "FBCA"), the holders of shares of Series A Preferred Stock shall vote
together with the holders of Class A Common Stock, Class B Common Stock and
Series C Preferred Stock as a single voting group on all actions to be taken by
the shareholders of the Corporation. Each share of Series A Preferred Stock
shall entitle the holder thereof to such number of votes per share on each such
action as shall equal (i) the largest number of whole shares of Class A Common
Stock into which such shares of Series A Preferred Stock could be converted,
pursuant to the provisions of Sections A.5, A.6 or A.7 hereof, multiplied by
(ii) ten (10) at the record date for the determination of shareholders entitled
to vote on such matter or, if no such record date is established, at the date
such vote is taken or any written consent of shareholders is solicited.

     (b)  Except as expressly provided herein or as required by law, as long as
20% or more of the greatest number of shares of Series A Preferred Stock issued
remain outstanding, the Corporation shall not, without the approval by vote or
written consent of the holders of at least 662/3% of the outstanding shares of
Series A Preferred Stock; (i) authorize or issue any class or series of equity
securities having equal or superior rights to the Series A Preferred Stock as to
payment upon liquidation, dissolution or a winding up of the Corporation; (ii)
enter into any agreement that would restrict the Corporation's ability to
perform under any purchase agreement

                                       3
<PAGE>

executed by the Corporation in connection with an issuance of Series A Preferred
Stock; (iii) amend its Articles of Incorporation or Bylaws in any way which
adversely affects the rights and preferences of the holders of Series A
Preferred Stock as a class; (iv) sell or lease 20% or more of its assets, except
in the ordinary course of business; (v) issue additional securities to
employees, officers or directors, except securities issuable upon the exercise
of options and warrants outstanding immediately prior to the issuance of any
Series A Preferred Stock, or issuable upon the exercise of options granted in
the future at fair market value; (vi) issue any securities for a price less than
fair market value, other than as may be required by contractual commitments
existing prior to the issuance of any Series A Preferred Stock; or (vii) adopt
any stock option plan other than the Corporation's 1996 Stock Option Plan or
increase the number of shares available for issuance under such plan.

     (c)  The holders of the Series A Preferred Stock and Series C Preferred
Stock, voting together as a single class, shall be entitled to elect two-fifths
(2/5) of the number of directors on the Board of Directors of the Corporation.

4.   Redemption.
     ----------

     (a)  Commencing on the fifth anniversary of the initial sale of the Series
A Preferred Stock (the "Redemption Commencement Date"), the Corporation shall,
to the extent it may do so under applicable law, redeem all of the outstanding
shares of Series A Preferred Stock at a price equal to the Series A Base
Liquidation Amount at the time of redemption. Such redemption shall occur in two
payments, the first to occur on the Redemption Commencement Date and the second
to occur one (1) year thereafter (each a "Payment Date"). Each payment (a
"Redemption Payment") shall be in an amount equal to one-half of the Series A
Base Liquidation Amount calculated as of the date of such payment, with the
final Redemption Payment in an amount necessary to fully redeem all remaining
outstanding Series A Preferred Stock at a price equal to the Series A Base
Liquidation Amount.

     (b)  On each Payment Date, the Corporation shall redeem shares of Series A
Preferred Stock ratably from the holders thereof to the extent of the Redemption
Payment due on such date, according to the respective amounts which would be
payable with respect to the full number of Series A Preferred Stock to be
redeemed from them on such date, as if all such Series A Preferred Stock were
redeemed in full. The Redemption Payment shall be payable in cash in immediately
available funds on the Payment Date. Any outstanding shares of Series A
Preferred Stock not redeemed shall remain outstanding. All shares of Series A
Preferred Stock which are to be redeemed hereunder shall remain issued and
outstanding until the Redemption Price therefor has been indefeasibly paid in
full in cash or has been deposited with an independent payment agent pursuant to
Section A.4(c). Any Series A Preferred Stock which would otherwise be redeemed
on a Payment Date may be converted by the holder thereof to Class A Common Stock
and Series B Preferred Stock, in accordance with the provisions hereof, at any
time prior to the close of business on the last business day next preceding such
Payment Date.

     (c)  On or before the Redemption Commencement Date, the Corporation will
give written notice by mail, postage prepaid to the holders of record of Series
A Preferred Stock to be

                                       4
<PAGE>

redeemed, such notice to be addressed to each such holder at its post office
address shown by the records of the Corporation, specifying the place of such
redemption; provided, however, that the Corporation's failure to give such
notice shall in no way affect its obligation to redeem the shares of Series A
Preferred Stock as provided in this Section A.4. If on or before a Payment Date,
the funds necessary for satisfaction of the Redemption Payment on such date
shall have been deposited with an independent payment agent so as to be, and
continue to be, available for such redemption, then, notwithstanding that any
certificate for shares of Series A Preferred Stock to be redeemed shall not have
been surrendered for cancellation, from and after the close of business on the
Payment Date, the shares to be redeemed as of such Payment Date shall no longer
be deemed outstanding, any dividends thereof shall cease to accrue, and all
rights with respect to such shares shall forthwith cease, except the conversion
rights pursuant to Sections A.5 and A.6, and the right of the holders thereof to
receive, upon presentation of the certificate representing shares so called for
redemption, the Redemption Payment applicable to such Series A Preferred Stock
without interest thereon.

     (d)  If the funds of the Corporation legally available for redemption of
Series A Preferred Stock on a Payment Date are insufficient to pay the
Redemption Payment then due and to redeem the number of outstanding Series A
Preferred Stock to be redeemed on such Payment Date, the Corporation shall
redeem such shares of Series A Preferred Stock ratably from the holders thereof
to the extent of any funds legally available for redemption of such Series A
Preferred Stock, according to the respective amounts which would be payable with
respect to the full number of Series A Preferred Stock to be redeemed from them
on such date, as if all such Series A Preferred Stock were redeemed in full. At
any time thereafter when additional funds of the Corporation are legally
available for the redemption of Series A Preferred Stock, such funds will be
used to redeem the balance of such Series A Preferred Stock which would have
otherwise been redeemed on such Payment Date, or such portion thereof for which
funds are then available, on the basis set forth above.

     (e)  Subsequent to the Redemption Commencement Date, until the full Series
A Base Liquidation Amount has been paid in cash for all outstanding shares of
Series A Preferred Stock: (A) no dividend whatsoever shall be paid or declared,
and no distribution shall be made, on any capital stock of the Corporation other
than shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock; and (B) no shares of capital stock
of the Corporation (other than the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or the Series D Preferred Stock) shall be
purchased, redeemed or acquired by the Corporation and no monies shall be paid
into or set aside or made available for a sinking fund for the purchase,
redemption or acquisition thereof.

     (f)  Upon receipt of the applicable Redemption Payment by certified check
or wire transfer, each holder of shares of Series A Preferred Stock to be
redeemed shall surrender the certificate or certificates representing such
shares to the Corporation, duly assigned or endorsed for transfer (or
accompanied by duly executed stock powers relating thereto), or shall deliver an
Affidavit of Loss with respect to such certificates at the principal executive
office or the Corporation or the office of the transfer agent for the Series A
Preferred Stock or such office or offices in the continental United States of an
agent for redemption as may from time to time be

                                       5
<PAGE>

designated by notice to the holders of Series A Preferred Stock and each
surrendered certificate shall be canceled and retired.

     (g)  All shares of Series A Preferred Stock acquired by the Corporation by
reason of redemption, purchase, conversion or otherwise shall be returned to the
status of authorized, unissued and undesignated shares of the Corporation's
preferred stock, and all such shares shall no longer be governed by this
Statement of Designation, Preferences, Rights and Limitations.

     (h)  Notwithstanding anything in this Section A.4 to the contrary, the
Corporation shall not be permitted to effect any redemption of the Series A
Preferred Stock, and no holder thereof shall have any right to have his or her
shares of Series A Preferred Stock redeemed by the Corporation, if at that time
such redemption is not permitted by the terms and provisions of the Indenture or
any refinancing thereof.

5.   Optional Conversion.
     -------------------

     (a)  Beginning on and at all times after the effective date of this Second
Amended and Restated Statement of Designation, Preferences, Rights and
Limitations, the holder of each single share of the outstanding Series A
Preferred Stock of the Corporation shall have the right to surrender the
certificate or certificates evidencing such share(s) and receive, in lieu and in
conversion thereof for each one (1) share of Series A Preferred Stock of the
Corporation so surrendered, a certificate evidencing (i) a number of shares of
Class A Common Stock of the Corporation equal to the quotient obtained by
dividing $3.726708075 by the then applicable Conversion Price, plus (ii) one (1)
share of Series B Preferred Stock of the Corporation. The "Conversion Price" of
the Series A Preferred Stock is initially $3.726708075, subject to adjustment as
provided in Section A.7(a) hereof. Fractional shares of Series A Preferred Stock
may not be surrendered. Except as provided in Section A.1.(b) hereof,
accumulated but unpaid dividends on the shares of Series A Preferred Stock
converted shall be paid at the time of conversion, and such dividends are not
convertible into Class A Common Stock or Series B Preferred Stock.

     (b)  In the event the Corporation shall, at any time that any of the shares
of Series A Preferred Stock are outstanding, be consolidated with or merged into
any other corporation or corporations, or sell or lease all or substantially all
of its property and business as an entirety, then lawful provision shall be made
as part of the terms of such consolidation, merger, sale, or lease for the
holder of any shares of Series A Preferred Stock thereafter to receive in lieu
of such shares of Class A Common Stock and Series B Preferred Stock otherwise
issuable to him upon conversion of his shares of Series A Preferred Stock, but
at the Conversion Price which would otherwise be in effect at the time of
conversion as hereinbefore provided, the same kind and relative amount of
securities or assets as may be issuable, distributable, or payable upon such
consolidation, merger, sale or lease, with respect to shares of Class A Common
Stock of the Corporation.

     (c)  The Corporation need not issue fractional shares in satisfaction of
the conversion privilege of the shares of Series A Preferred Stock but, in lieu
of fractional shares, the Corporation at its option may make a cash settlement
in respect thereof equal to the purchase

                                       6
<PAGE>

price of such Series A Preferred Stock, as adjusted in accordance with Section
A.7(a), multiplied by such fractional share amount, or may issue scrip
certificates exchangeable together with other such scrip certificates
aggregating one or more full shares for certificates representing such full
share or shares. Until the exchange thereof for certificates representing full
shares of Class A Common Stock and Series B Preferred Stock, the holder of any
such scrip certificates shall not be entitled to receive dividends thereon, to
vote with respect thereto, or to have any other rights by virtue thereof as a
shareholder of the Corporation, except such rights, if any, as the Board of
Directors may in its discretion determine in the event of dissolution of the
Corporation.

     (d)  The right of conversion of any holder of Series A Preferred Stock
shall be exercisable only if he or she provides thirty (30) days prior written
notice, by certified or registered mail, addressed to the attention of the
Secretary of the Corporation at the principal office of the Corporation, of his
or her intention to surrender shares of Series A Preferred Stock for conversion.
Such conversion notice shall state the number of shares of Series A Preferred
Stock to be converted.

     (e)  As promptly as practicable after the surrender for conversion of any
Series A Preferred Stock and considering the requirements for and in conformity
with all applicable laws, including, but not limited to, the Securities Act of
1933, as amended, the Corporation shall deliver or cause to be delivered at the
principal office of the Corporation (or such other places as may be designated
by the Corporation) to or upon the written order of the holder of such Series A
Preferred Stock, certificates representing the shares of Class A Common Stock
and Series B Preferred Stock, issuable upon such conversion, issued in such name
or names as such holder may direct. Shares of the Series A Preferred stock shall
be deemed to have been converted as of the close of business on the date of the
surrender of the Series A Preferred Stock for conversion and the rights of the
holders of such Series A Preferred Stock shall cease at such time, and the
person or persons in whose name or names the certificates for such surrender are
to be issued shall be treated for all purposes as having become the record
holder or holders of such Class A Common Stock and Series B Preferred Stock at
such time; provided, however, that if the surrender is on any date when the
stock transfer books of the Corporation shall be closed, the person or persons
in whose name or names the certificates for such shares are to be issued shall
be treated as the record holder or holders thereof for all purposes at the close
of business on the next succeeding day on which such stock transfer books are
open.

     (f)  The issuance of certificates for shares of Class A Common Stock and
Series B Preferred Stock upon conversion of the Series A Preferred Stock shall
be made without charge for any tax in respect of such issuance. However, if any
certificate is to be issued in a name other than that of the holder of record of
the Series A Preferred Stock so converted, the person or persons requesting the
issuance thereof shall pay to the Corporation the amount of any tax which may be
payable in respect of any transfer involved in such issuance, or shall establish
to the satisfaction of the Corporation that such tax has been paid or is not due
and payable.

6.   Automatic Conversion.
     --------------------

     (a)  Each outstanding share of Series A Preferred Stock shall automatically
be converted into (i) a number of shares of Class A Common Stock equal to the
quotient obtained by dividing $3.726708075 by the then applicable Conversion
Price, plus (ii) one (1) share of Series B Preferred Stock, immediately upon the
first to occur of either of the following events (each, an "Automatic Conversion
Event"): (A) the authorization of such conversion, including without limitation
in an action by written consent in accordance with Section 607.0704, Florida
Statutes, as amended from time to time, by the holders of not less than two-
thirds (66 2/3%) of all of the then issued and outstanding shares of Series A
Preferred Stock, or (B) the consummation by the Corporation of a public offering
of its securities which offering shall (x) raise total gross proceeds to the
Corporation of greater than or equal to $20,000,000 and (y) have a per share
offering price (I) if such offering is consummated on or before June 30, 1998,
greater than or equal to 150% of the then applicable Conversion Price, or (II)
if such offering is consummated after June 30, 1998, greater than or equal to
200% of the then applicable Conversion Price (a "Qualified Public Offering").

     (b)  On or after the date of an occurrence of an Automatic Conversion
Event, and in any event within ten (10) days after receipt of notice, by mail,
postage prepaid from the Corporation of the occurrence of such event, each
holder of record of shares of Series A Preferred Stock shall surrender such
holder's certificates evidencing such shares at the principal office of the
Corporation or at such other place as the Corporation shall designate, and shall
thereupon be entitled to receive certificates evidencing the number of shares of
Class A Common Stock and Series B Preferred Stock into which such shares of
Series A Preferred Stock are converted. Notwithstanding any other provisions
herein to the contrary, on the date of the occurrence of an Automatic Conversion
Event, each holder of record of the shares of Series A Preferred Stock shall be
deemed to be the holder of record of the Class A Common Stock and Series B
Preferred Stock issuable upon such conversion and no shares of Series A
Preferred Stock shall be considered outstanding notwithstanding that the
certificates representing such shares of Series A Preferred Stock shall not have
been surrendered at the office of the Corporation, that notice from the
Corporation shall not have been received by any holder of record of shares of
Series A Preferred Stock, or that the certificates evidencing such shares of
Class A Common Stock and Series B Preferred Stock shall not then be actually
delivered to such holder; provided, however, that the Corporation shall not be
obligated to issue certificates evidencing the shares of Class A Common Stock
and Series B Preferred Stock issuable upon such conversion unless certificates
evidencing such shares of the Series A Preferred Stock being converted are
either delivered to the Corporation or its transfer agent, or the holder
notifies the Corporation or its transfer agent that such certificates have been
lost, stolen or destroyed and executes an agreement satisfactory to the
Corporation to indemnify the Corporation from any loss incurred by it in
connection therewith.

7.   Provisions Relating to Automatic and Optional Conversions.
     ---------------------------------------------------------

     (a)  Adjustments to Conversion Price.
          -------------------------------

          (i)  Subdivision, Combination or Reclassification of Class A Common
               --------------------------------------------------------------
               Stock.
               -----

               (A)  If the Corporation shall, while there are any shares of
                    Series A Preferred Stock issued and outstanding, effect a
                    subdivision of its shares of Common Stock into a greater
                    number of such shares or a combination of such shares into a
                    lesser number of shares, whether by forward or reverse stock
                    split, stock dividend (payable in shares of Common Stock) or
                    otherwise, the Conversion Price shall be proportionally
                    increased or reduced, as the case may be, to reflect the
                    effectuation of such subdivision or combination.

               (B)  If the Corporation shall, while there are any shares of
                    Series A Preferred Stock issued and outstanding, effect a
                    capital reorganization or reclassification of the Common
                    Stock or any distribution by the Corporation to holders of
                    Class A Common Stock, whether in the form of stock, debt
                    securities, or other assets or property of the Corporation,
                    (each, an "Adjustment Event"), then, as a condition of such
                    Adjustment Event, lawful and adequate provision shall be
                    made whereby the holders of the Series A Preferred Stock
                    shall thereafter have the right to acquire and receive upon
                    conversion of the Series A Preferred Stock such shares of
                    stock, securities, assets or property as would have been
                    issuable or payable as a result of such Adjustment Event
                    with respect to or in exchange for such number of
                    outstanding shares of the Class A Common Stock as would have
                    been received as if such Series A Preferred Stock were
                    converted immediately prior to the consummation of such
                    Adjustment Event.

               (C)  In the event that an Adjustment Event shall occur by means
                    of a merger, consolidation, combination, share exchange, or
                    sale or lease of all or substantially all the assets of the
                    Corporation, then as a condition of such Adjustment Event,
                    lawful and adequate provision shall be made whereby the
                    holders of the Series A Preferred Stock shall thereafter
                    have the rights to acquire and receive upon conversion of
                    their shares of Series A Preferred Stock, such shares of
                    stock, securities or assets as would have been issuable or
                    payable as part of such Adjustment Event with respect to or
                    in exchange for such number of outstanding shares of the
                    Class A Common Stock as would have been received upon
                    conversion of the Series A Preferred Stock (in all
                    instances) immediately before such Adjustment Event, and in
                    any such case

                    appropriate provisions shall be made with respect to the
                    rights and interests of the holders of the Series A
                    Preferred Stock such that the provisions hereof (including
                    without limitation provisions for adjustments of the
                    Conversion Price and of the number of shares of Class A
                    Common Stock acquirable and receivable upon the conversion
                    of the Series A Preferred Stock) shall thereafter be
                    applicable, in relation to any shares of stock, securities
                    or assets thereafter deliverable upon the conversion of the
                    Series A Preferred Stock (including an immediate adjustment,
                    by reason of such Adjustment Event of the Series A Preferred
                    Stock to the value for the Class A Common Stock reflected by
                    the terms of such Adjustment Event if the value so reflected
                    is less than the Conversion Price in effect immediately
                    prior to such Adjustment Event). In the event of an
                    Adjustment Event as a result of which a number of shares of
                    Common Stock of the surviving or purchasing corporation is
                    greater or lesser than the number of shares of Common Stock
                    of the Corporation outstanding immediately prior to such
                    Adjustment Event, then the Conversion Price in effect
                    immediately prior to such Adjustment Event shall be adjusted
                    in the same manner as though there were a subdivision or
                    combination of the outstanding shares of Class A Common
                    Stock of the Corporation. The Corporation will not effect
                    any such Adjustment Event unless prior to the consummation
                    thereof the successor corporation (if other than the
                    Corporation) resulting from such consolidation or merger or
                    the purchase or lease of such assets shall assume by written
                    instrument mailed or delivered to the holders of the Series
                    A Preferred Stock at the last address of each such holder
                    appearing on the books of the Corporation, the obligation to
                    deliver to each such holder such shares of stock, securities
                    or assets as, in accordance with the foregoing provisions,
                    such holder may be entitled.

          (ii) Issuance of Common Stock.  Except as provided in Sections
               ------------------------
               A.7(a)(iii) and A.7(a)(iv), if and whenever the Corporation shall
               issue or sell, or shall in accordance with subparagraphs (A)
               through (F), inclusive, of Section A.7(a)(iii) be deemed to have
               issued or sold, any shares of its Class A Common Stock, or
               options, warrants or other rights to purchase Class A Common
               Stock or securities convertible into Class A Common Stock, for a
               consideration per share less than the Conversion Price in effect
               immediately prior to the time of such issuance or sale, then
               forthwith upon such issuance or sale, the Conversion Price shall,
               subject to subparagraphs (A) to (F) of Section A.7(a)(iii), be
               reduced to:

                                      10
<PAGE>

                 (A)  For issuances or sales on or before 18 months after the
                      date of the first issuance of Series A Preferred Stock,
                      the Conversion Price shall equal such issuance or sale
                      price.

                 (B)  For issuances or sales after 18 months from the date of
                      the first issuance of Series A Preferred Stock, the
                      Conversion Price shall be determined by multiplying the
                      Conversion Price in effect immediately prior to such
                      issuance or sale by a fraction; the numerator of which
                      shall be (1) the number of shares of Class A Common Stock
                      outstanding immediately prior to the issuance of such
                      additional shares of Class A Common Stock, plus (2) the
                      number of shares of Class A Common Stock which the net
                      aggregate consideration, if any, received by the
                      Corporation for the total number of such additional shares
                      of Class A Common Stock so issued would purchase at the
                      Conversion Price in effect immediately prior to such
                      issuance, and; the denominator of which shall be (1) the
                      number of shares of Class A Common Stock outstanding
                      immediately prior to the issuance of such additional
                      shares of Class A Common Stock plus (2) the number of such
                      additional shares of Class A Common Stock so issued.

          (iii)  For purposes of determining the adjusted Conversion Price under
                 Section A.7(a)(ii)(A) and (B), the following subsections (A) to
                 (F), inclusive, shall be applicable:

                 (A)  Issuance of Rights or Options. Except as provided Section
                      -----------------------------
                      A.7(a)(iv), in case at any time the Corporation shall in
                      any manner grant (whether directly or by assumption in a
                      merger or otherwise) any rights to subscribe for or to
                      purchase, or any options for the purchase of, Class A
                      Common Stock or any stock or other securities convertible
                      into or exchangeable for Class A Common Stock (such rights
                      or options being herein called "Options" and such
                      convertible or exchangeable stock or securities being
                      herein called "Convertible Securities") whether or not
                      such Options or the right to convert or exchange any such
                      Convertible Securities are immediately exercisable, and
                      the price per share for which such Class A Common Stock is
                      issuable upon the exercise of such Options or upon
                      conversion or exchange of such Convertible Securities
                      (determined by dividing (x) the total amount, if any,
                      received or receivable by the Corporation as consideration
                      for the granting of such Options, plus the minimum
                      aggregate amount of additional consideration payable to
                      the Corporation upon the exercise of all such Options,
                      plus, in the case of such Options which relate to
                      Convertible Securities, the minimum aggregate amount of
                      additional consideration, if any, payable upon the issue

                      conversion or exchange thereof, by (y) the total maximum
                      number of shares of Class A Common Stock issuable upon the
                      exercise of such Options) shall be less than the
                      Conversion Price in effect immediately prior to the time
                      of the granting of such Option, then the total maximum
                      number of shares of Class A Common Stock issuable upon the
                      exercise of such Options or upon conversion or exchange of
                      the total maximum amount of such Convertible Securities
                      issuable upon the exercise of such Options shall (as of
                      the date of granting of such Options) be deemed to be
                      outstanding and to have been issued by the Corporation for
                      such price per share. No adjustment of the Conversion
                      Price shall be made upon the actual issuance of such
                      Convertible Securities except as otherwise provided in
                      subsection (C) below.

                 (B)  Issuance of Convertible Securities. In case the
                      ----------------------------------
                      Corporation shall in any manner issue (whether directly or
                      by assumption in a merger or otherwise) or sell any
                      Convertible Securities, whether or not the rights to
                      exchange or convert thereunder are immediately
                      exercisable, and the price per share for which such Class
                      A Common Stock is issuable upon such conversion or
                      exchange (determined by dividing (x) the total amount
                      received or receivable by the Corporation as consideration
                      for the issuance or sale of such Convertible Securities,

                      consideration, if any, payable to the Corporation upon the
                      conversion or exchange thereof, by (y) the total maximum
                      number of shares of Class A Common Stock issuable upon the
                      conversion or exchange of all such Convertible Securities)
                      shall be less than the Conversion Price in effect
                      immediately prior to the time of such issuance or sale,
                      then the total maximum number of all such Convertible
                      Securities shall (as of the date of the issue or sale of
                      such Convertible Securities) be deemed to be outstanding
                      and to have been issued and sold by the Corporation for
                      such price per share, provided that, except as otherwise
                      specified in subsection (C) below, no adjustment of the
                      Conversion Price shall be made upon the actual issue of
                      such Class A Common Stock upon exercise of any Options for
                      which adjustments of the Conversion Price have been or are
                      to be made pursuant to other provisions of this Section
                      A.7(a) and no further adjustment of the Conversion Price
                      shall be made by reason of such issuance or sale.

                 (C)  Change in Option Price or Conversion Rate. If the purchase
                      -----------------------------------------
                      price provided for in any Option referred to in

                      Convertible Securities referred to in subparagraphs (A) or
                      (B) are convertible into or exchangeable for Class A
                      Common Stock, shall change at any time (other than under
                      or by reason of provisions designed to protect against
                      dilution of the type set forth in Section A.7(a)), the
                      Conversion Price in effect at the time of such change
                      shall forthwith be readjusted to the Conversion Price
                      which would have been in effect at such time had such
                      Options or Convertible Securities still outstanding
                      provided for such changed purchase price, additional
                      consideration, or conversion rate, as the case may be, at
                      the time initially granted, issued or sold. If the
                      purchase price provided for in any Option referred to in
                      subsection (A), or the rate at which any Convertible
                      Securities referred to in subparagraphs (A) or (B) are
                      convertible into or exchangeable for Class A Common Stock,
                      shall be reduced at any time under or by reason or
                      provisions with respect thereto designed to protect
                      against dilution, then in case of the delivery of Class A
                      Common Stock upon the exercise of any such Option or upon
                      conversion or exchange of any such Convertible Security,
                      the Conversion Price then in effect hereunder shall
                      forthwith be adjusted to such respective amount as would
                      have been obtained had such Option or Convertible Security
                      never been issued as to such Class A Common Stock and had
                      adjustments been made upon the issuance of the shares of
                      Class A Common Stock delivered as aforesaid, but only if
                      as a result of such adjustment the Conversion Price then
                      in effect hereunder is hereby reduced.

                 (D)  Treatment of Expired Options and Unexercised Convertible
                      --------------------------------------------------------
                      Securities.  On the expiration of any Option or the
                      ----------
                      termination of any right to convert or exchange any
                      Convertible Securities, the Conversion Price then in
                      effect hereunder shall forthwith be increased to the
                      Conversion Price which would have been in effect at the
                      time of such expiration or termination had such Option or
                      Convertible Securities, to the extent outstanding
                      immediately prior to such expiration or termination, never
                      been issued.

                 (E)  Integral Transaction.  In case any Options shall be issued
                      --------------------
                      in connection with the issue or sale of other securities
                      of the Corporation, together comprising one integral
                      transaction in which no specific consideration is
                      allocated to such Options by the parties thereto, such
                      Options shall be deemed to have been issued without
                      consideration.

                 (F)  Consideration for Stock.  In case any shares of Class A
                      -----------------------
                      Common Stock, Options or Convertible Securities shall be
                      issued or sold or

<PAGE>

                      deemed to have been issued or sold for cash, the
                      consideration received therefor shall be deemed to be the
                      amount received by the Corporation therefor. In case any
                      shares of Class A Common Stock, Options, or Convertible
                      Securities shall be issued or sold for a consideration
                      other than cash, the amount of the consideration other
                      than cash received by the Corporation shall be the fair
                      value of such consideration. In case any shares of Class A
                      Common Stock, Options, or Convertible Securities shall be
                      issued in connection with any merger in which the
                      Corporation is the surviving corporation, the amount of
                      consideration therefor shall be deemed to be the fair
                      value of such portion of the net assets and business of
                      the non-surviving corporation as shall be attributable to
                      such Class A Common Stock, Options, or Convertible
                      Securities, as the case may be. In the event of any
                      consolidation or merger of the Corporation in which the
                      Corporation is not the surviving corporation, or, in the
                      event of any sale of all or substantially all of the
                      assets of the Corporation for stock or other securities of
                      any corporation, this subsection shall be applied in the
                      same manner as if the Corporation had been the surviving
                      corporation in such consolidation or merger, or the
                      purchasing corporation in such sale of assets; and for
                      purposes of this sentence the Corporation shall be deemed:

                      (1)  to have issued and sold a number of shares of its
                           Class A Common Stock, Options, or Convertible
                           Securities equal to the sum of (x) the number of
                           shares of the Corporation's Class A Common Stock
                           actually outstanding, (y) the number of shares of the
                           Corporation's Class A Common Stock acquirable upon
                           the exercise of all outstanding Options, and (z) the
                           number of shares of the Corporation's Class A Common
                           Stock acquirable upon conversion of all outstanding
                           Convertible Securities, which those persons who were
                           security holders of the surviving corporation
                           immediately before the consummation of the
                           transaction would have received in exchange for the
                           common stock, options, and convertible securities of
                           the surviving corporation held by them immediately
                           after consummation of the transaction, based on the
                           exchange ratio on which the transaction was
                           consummated (i.e., the inverse of the ratio pursuant
                           to which the Corporation's Class A Common Stock were
                           exchangeable into the surviving corporation's
                           securities) and assuming that Corporation had been
                           the surviving corporation; and

                      (2)  to have received in exchange therefor a consideration
                           equal to the fair market value (immediately before
                           the consummation of such transaction) of the assets
                           (less the liabilities) of the surviving corporation;
                           and if the application of this sentence results in
                           adjustment of the Conversion Price and number of
                           Conversion Shares issuable upon conversion of the
                           Series A Preferred Stock, then the determination of
                           the Conversion Price and the number of Conversion
                           Shares issuable upon conversion of the Series A
                           Preferred Stock immediately prior to such merger,
                           consolidation, or sale shall be made after giving
                           effect to the adjustment set forth herein. If the
                           stock of the surviving or purchasing corporation in
                           such a transaction is publicly traded, the market
                           value of such corporation's outstanding stock
                           immediately before consummation of the exchange shall
                           be presumptive evidence of the fair market value of
                           its assets (less liabilities).

          (iv) Notwithstanding anything in Section A.7 to the contrary, no
               adjustment shall be made to the Conversion Price upon (w) the
               issuance of any shares of Class A Common Stock, options or
               Convertible Securities in connection with an acquisition by the
               Corporation or a merger in which the Corporation is the surviving
               corporation, calculated on a fully diluted basis and further
               provided such issuance is to the sellers of the acquired entity
               or assets or security of the merged entity and is made for fair
               value and the Board of Directors of the Corporation determines
               that the acquisition or merger is in the best interests of the
               Corporation and its stockholders; (x) the issuance of any shares
               of Class A Common Stock upon conversion of any shares of Series A
               Preferred Stock; (y) the issuance of Class A Common Stock upon
               the exercise of any options, warrants or other rights to purchase
               Class A Common Stock outstanding on the date of the first
               issuance of Series A Preferred Stock, including the warrant to be
               issued to Alex. Brown & Sons Incorporated in connection with the
               initial sale of Series A Preferred Stock or (z) the future
               issuance of Class A Common Stock or warrants, options or rights
               to purchase such Class A Common Stock to employees, consultants,
               directors or vendors directly or pursuant to plans approved by
               the Board of Directors so long as such options are granted at
               fair market value.

     (b)  The Corporation shall at all times reserve and keep available out of
its authorized but unissued shares of Class A Common Stock solely for the
purpose of effecting the conversion of the shares of Series A Preferred Stock
pursuant to Sections A.5 and A.6 hereof, such number of its shares of Class A
Common Stock and Series B Preferred Stock as shall from time to time be
sufficient to effect such conversion of all outstanding shares of the Series A
Preferred Stock; and, if at any time the number of authorized but unissued
shares of Class A Common Stock or

                                       15
<PAGE>

Series B Preferred Stock shall not be sufficient to effect the conversion of all
of the then outstanding shares of Series A Preferred Stock, the Corporation will
take such corporate action as may, in the opinion of its counsel be necessary to
increase its authorized but unissued shares of Class A Common Stock or Series B
Preferred Stock to such number of shares as shall be sufficient for such
purposes.

8.   Preemptive Rights.
     -----------------

     (a)  At any time after the first closing of the sale of the Series A
Preferred Stock but prior to the filing of effective registration statement
relating to a Qualified Public Offering, or from time to time prior thereto, if
the Corporation shall issue, grant or sell any of its equity securities, the
Corporation shall, in each such case, offer a pro rata share of any such
issuance, grant or sale to the holders of Series A Preferred Stock and Series C
Preferred Stock. If any holders of Series A Preferred Stock or Series C
Preferred Stock determine not to accept their pro rata share, then the other
Series A Preferred Stock holders and Series C Preferred Stockholders shall be
given the right to accept such share on a pro rata basis.

     (b)  Notwithstanding the foregoing, the preemptive rights set forth in
Section A.8(a) shall not apply in the event of any issue, grant or sale in
connection with (i) a merger, consolidation, combination, share exchange or sale
or lease of all or substantially all assets of the Corporation or another
corporation; (ii) conversion of Series A Preferred Stock pursuant to Sections
A.5 or A.6 hereof; (iii) the exercise of options, warrants or other rights to
purchase stock outstanding prior to the issuance of any Series A Preferred
Stock; (iv) any stock option or other employee benefit plans of the Corporation
and (v) the grant or exercise of a warrant to purchase Class A Common Stock
issued to Alex. Brown & Sons Incorporated in connection with the initial sale of
Series A Preferred Stock.  In any event, all preemptive rights shall expire and
be of no further force and effect upon the effectiveness of a registration
statement relating to a Qualified Public Offering.

9.   No Impairment of Rights.
     -----------------------

     Other than pursuant to the provisions of Section E hereunder, the
Corporation will not, by amendment of the Articles of Incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of the Series A
Preferred Stock set forth herein, and will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may
be necessary or appropriate in order to protect the rights of the holders of the
Series A Preferred Stock against dilution or other impairment. Without limiting
the generality of the foregoing, other than pursuant to the provisions of
Section E hereunder, the Corporation (i) will not increase the par value of any
shares of stock receivable on the conversion of the Series A Preferred Stock
above the amount payable therefor on such conversion, and (ii) will take all
such action as may be necessary or appropriate in order that the Corporation may
validly and legally issue fully paid and non-assessable shares of stock on the
conversion of all Series A Preferred Stock under the terms hereof from time to
time outstanding.

          B.   4% SERIES B REDEEMABLE PREFERRED STOCK
               --------------------------------------

1.   Dividends.
     ---------

     (a)  The holders of outstanding shares of Series B Preferred Stock shall be
entitled, in preference to the holders of any and all other classes of capital
stock of the Corporation (other than the Series A Preferred Stock, Series C
Preferred Stock, and Series D Preferred Stock, which will rank equally with the
Series B Preferred Stock as to dividends), to receive, out of any funds legally
available therefor, cumulative dividends on the Series B Preferred Stock in
cash, at the rate per annum of four percent (4%) of the Series B Base
Liquidation Amount (as defined in Section B.2 below), subject to proration for
partial years on the basis of a 365-day year ("Series B Cumulative Preference
Dividends"). Such dividends will accumulate commencing as of the date of
issuance of the Series B Preferred Stock and will be cumulative, to the extent
unpaid, whether or not they have been declared and whether or not there are
profits, surplus or other funds of the Corporation legally available for the
payment of dividends. Series B Cumulative Preference Dividends shall become due
and payable with respect to any share of Series B Preferred Stock as provided in
Section B.2 and Section B.4. Dividends paid in cash in an amount less than the
total amount of such dividends at the time accumulated and payable on all
outstanding shares of Series B Preferred Stock, including fractions, shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. At any time when shares of Series B Preferred Stock are outstanding
and the Series B Cumulative Preference Dividends have not been paid in full in
cash: (i) no dividend whatsoever shall be paid or declared, and no distribution
shall be made, on any capital stock of the Corporation ranking junior to the
Series B Preferred Stock; and no shares of capital stock of the Corporation
ranking junior to the Series B Preferred Stock shall be purchased, redeemed or
acquired by the Corporation and no monies shall be paid into or set aside or
made available for a sinking fund for the purchase, redemption or acquisition
thereof. All numbers relating to the calculation of dividends pursuant to this
Section B.1 shall be subject to equitable adjustment in the event of any stock
split, combination, reorganization, recapitalization, reclassification or other
similar event involving a change in the Series B Preferred Stock. At the time of
the fifth anniversary following the initial sale of the Series A Preferred
Stock, the dividend on the Series B Preferred Stock shall increase to 8% of the
Series B Base Liquidation Amount per annum. At the time of the sixth anniversary
following the initial sale of the Series A Preferred Stock, the dividend rate on
the Series B Preferred Stock shall increase to 14% of the Series B Base
Liquidation Amount per annum.

     (b)  Notwithstanding the foregoing, while any of the Senior Notes remain
outstanding, the Corporation shall not be permitted to pay any cash dividends
upon the Series B Preferred Stock (including any such dividends payable in
connection with a conversion of the Series B Preferred Stock) and the holders of
the Series B Preferred Stock shall not be entitled to receive any such
dividends, if and to the extent that such dividends would be prohibited by any
term or provision of the Indenture or any documents relating to any refinancing
of the Senior Notes; provided that the covenant under the caption "Restricted
                     --------
Payments" in the Indenture, or any documents relating to any refinancing of the
Senior Notes, will not be materially more restrictive with regard to payments
than the restrictions set forth in the covenant under the caption "Certain
Covenants--Restricted Payments" in the Referenced Document, and provided further
that no

                                       17
<PAGE>

such amendment, supplement or modification of the Indenture, or any documents
relating to any refinancing of the Senior Notes, shall (i) increase the
aggregate principal amount of Senior Notes outstanding, (ii) be materially more
restrictive with regard to payments than the restrictions set forth in the
covenant under the caption "Certain Covenants--Restricted Payments" in the
Referenced Document or (iii) extend the maturity of the Senior Notes. Any change
that will prohibit a payment that would otherwise be permitted pursuant to the
Referenced Document will be deemed material.

2.   Liquidation Preferences.
     -----------------------

     (a)  Upon any Event of Dissolution, each holder of an outstanding share of
Series B Preferred Stock shall be entitled to be paid out of the assets of the
Corporation available for distribution to stockholders, whether such assets are
capital, surplus, or earnings as follows, and before any amount shall be paid or
distributed to the holders of  Class A Common Stock or Class B Common Stock or
of any other stock ranking on liquidation junior to the Series B Preferred Stock
(other than the Series A Preferred Stock, the Series C Preferred Stock, and the
Series D Preferred Stock, which will rank equally with the Series B Preferred
Stock in an Event of Dissolution) an amount in cash equal to the sum of (a)
$3.726708075 per share (adjusted appropriately for stock splits, stock
dividends, recapitalizations and the like with respect to the Series B Preferred
Stock), plus (b) any accumulated but unpaid dividends to which such holder of
outstanding shares of Series B Preferred Stock is entitled pursuant to Section
B.1 hereof (the sum of (a) and (b) being referred to as the "Series B Base
Liquidation Amount"); provided, however, that if, upon any Event of Dissolution,
                      --------  -------
the amounts payable with respect to the Series B Preferred Stock are not paid in
full, the holders of the Series B Preferred Stock shall share ratably in any
distribution of assets in proportion to the full respective preferential amounts
to which they are entitled.

     (b)  After full payment shall have been made to the holders of shares of
the Series B Preferred Stock (and Series A Preferred Stock, Series C Preferred
Stock and Series D Preferred Stock in accordance with Sections A.2, C.2 and
D.2), any balance of the assets of the Corporation then remaining shall be
allocated to the holders of shares of other classes of stock ranking junior to
the Series B Preferred Stock, including the holders of Class A Common Stock and
Class B Common Stock, in accordance with the respective interests therein.

3.   Voting Rights.
     -------------

     The holders of Series B Preferred Stock shall not be entitled to vote on
any matters except those contemplated by Section E and to the extent otherwise
required under the FBCA.

4.   Redemption.
     ----------

     (a)  The Corporation shall redeem the Series B Preferred Stock as follows:

          (i)  The Corporation shall, upon consummation of a Qualified Public
               Offering, to the extent it may do so under applicable law and to
               the extent it may do so under Section B.4(a)(ii), redeem all of
               the outstanding shares of Series

                                       18
<PAGE>

                B Preferred Stock at a price equal to the Series B Base
                Liquidation Amount as of the date of such consummation. For
                redemptions required under this Section B.4(a)(i), the "Payment
                Date" shall be the date of consummation of a Qualified Public
                Offering, and the "Redemption Payment" shall be the aggregate
                Series B Base Liquidation Amount.

          (ii)  The managing underwriter of the Qualified Public Offering shall
                have the right to limit the redemption of all or any part of the
                Series B Preferred Stock then outstanding. In such event, the
                part of the Series B Preferred Stock not redeemed shall
                automatically convert into a three year obligation (the
                "Obligation") payable to the holder thereof in the principal
                amount of the Series B Base Liquidation Amount. Principal and
                interest on each Obligation shall be payable quarterly, with
                interest at the rate of 2% over the Prime Rate during the first
                year, 4% over the Prime Rate during the second year, and 6% over
                the Prime Rate during the third year after issuance. "Prime
                Rate" shall mean the prime rate reported from time to time in
                The Wall Street Journal, initially on the date the Series B
                -----------------------
                Preferred Stock converts into the Obligation, and each
                anniversary thereafter. In the event that any quarterly payment
                on the Obligations is not paid when due, the interest rate
                applicable over the remaining life of the Obligations shall be
                increased to 6% over the Prime Rate.

          (iii) Commencing on the fifth anniversary of the initial sale of the
                Series A Preferred Stock, the Corporation shall, to the extent
                it may do so under applicable law, redeem all of the outstanding
                shares of Series B Preferred Stock at a price equal to the
                Series B Base Liquidation Amount at the time of redemption.

     (b)  Any redemption under Section B.4(a)(iii) shall occur in two payments,
the first to occur on the Redemption Commencement Date and the second to occur
one (1) year thereafter (each a "Payment Date").  Each payment (a "Redemption
Payment") shall be in an amount equal to one-half of the Series B Base
Liquidation Amount calculated as of the date of such payment, with the final
Redemption Payment in an amount necessary to fully redeem all remaining
outstanding Series B Preferred Stock at a price equal to the Series B Base
Liquidation Amount.

     (c)  On each Payment Date, the Corporation shall redeem shares of Series B
Preferred Stock ratably from the holders thereof to the extent of the Redemption
Payment due on such date, according to the respective amounts which would be
payable with respect to the full number of Series B Preferred Stock to be
redeemed from them on such date, as if all such Series B Preferred Stock were
redeemed in full. The Redemption Payment shall be payable in cash in immediately
available funds on the Payment Date. Any outstanding shares of Series B
Preferred Stock not redeemed shall remain outstanding. All shares of Series B
Preferred Stock which are to be redeemed hereunder shall remain issued and
outstanding until the Redemption Price therefor has been indefeasibly paid in
full in cash or has been deposited with an independent payment agent pursuant to
Section B.4(d).

                                       19
<PAGE>

     (d)  On or before the Redemption Commencement Date, the Corporation will
give written notice by mail, postage prepaid to the holders of record of Series
B Preferred Stock to be redeemed under Section B.4(a), such notice to be
addressed to each such holder at its post office address shown by the records of
the Corporation, specifying the place of such redemption; provided, however,
that the Corporation's failure to give such notice shall in no way affect its
obligation to redeem the shares of Series B Preferred Stock as provided in this
B.4. If on or before a Payment Date, the funds necessary for satisfaction of the
Redemption Payment under Section B.4(a) on such date shall have been deposited
with an independent payment agent so as to be, and continue to be, available for
such redemption, then, notwithstanding that any certificate for shares of Series
B Preferred Stock to be redeemed shall not have been surrendered for
cancellation, from and after the close of business on the Payment Date, the
shares to be redeemed as of such Payment Date shall no longer be deemed
outstanding, any dividends thereof shall cease to accrue, and all rights with
respect to such shares shall forthwith cease, except the right of the holders
thereof to receive, upon presentation of the certificate representing shares so
called for redemption, the Redemption Payment applicable to such Series B
Preferred Stock without interest thereon.

     (e)  If the funds of the Corporation legally available for redemption of
Series B Preferred Stock on the Payment Date are insufficient to pay the
Redemption Payment then due and to redeem the number of outstanding Series B
Preferred Stock to be redeemed on such Payment Date, the Corporation shall
redeem such shares of Series B Preferred Stock ratably from the holders thereof
to the extent of any funds legally available for redemption of such Series B
Preferred Stock, according to the respective amounts which would be payable with
respect to the full number of Series B Preferred Stock to be redeemed from them
on such date, as if all such Series B Preferred Stock were redeemed in full. At
any time thereafter when additional funds of the Corporation are legally
available for the redemption of Series B Preferred Stock, such funds will be
used to redeem the balance of such Series B Preferred Stock, which would have
otherwise been redeemed on such Payment Date, or such portion thereof for which
funds are then available, on the basis set forth above.

     (f)  Subsequent to the Redemption Commencement Date, until the full Series
B Base Liquidation Amount has been paid in cash for all outstanding shares of
Series B Preferred Stock: (A) no dividend whatsoever shall be paid or declared,
and no distribution shall be made, on any capital stock of the Corporation other
than shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock; and (B) no shares of capital stock
of the Corporation (other than the Series A Preferred Stock, the Series B
Preferred Stock, the Series C Preferred Stock or the Series D Preferred Stock)
shall be purchased, redeemed or acquired by the Corporation and no monies shall
be paid into or set aside or made available for a sinking fund for the purchase,
redemption or acquisition thereof.

     (g)  Upon receipt of the applicable Redemption Payment by certified check
or wire transfer, each holder of shares of Series B Preferred Stock to be
redeemed shall surrender the certificate or certificates representing such
shares to the Corporation, duly assigned or endorsed for transfer (or
accompanied by duly executed stock powers relating thereto), or shall deliver an
Affidavit of Loss with respect to such certificates at the principal executive
office or the

                                       20
<PAGE>

Corporation or the office of the transfer agent for the Series B Preferred Stock
or such office or offices in the continental United States of an agent for
redemption as may from time to time be designated by notice to the holders of
Series B Preferred Stock and each surrendered certificate shall be canceled and
retired.

     (h)  All shares of Series B Preferred Stock acquired by the Corporation by
reason of redemption, purchase, conversion or otherwise shall be returned to the
status of authorized, unissued and undesignated shares of the Corporation's
preferred stock, and all such shares shall no longer be governed by this
Statement of Designation, Preferences, Rights and Limitations.

     (i)  Notwithstanding anything in this Section B.4. to the contrary, the
Corporation shall not be permitted to effect any redemption of the Series B
Preferred Stock, and no holder thereof shall have any right to have his or her
shares of Series B Preferred Stock redeemed by the Corporation, if at that time
such redemption is not permitted by the terms and provisions of the Indenture or
any documents relating to any refinancing of the Senior Notes.  Any change that
will prohibit a payment that would otherwise be permitted pursuant to the
Referenced Document will be deemed material.

5.   No Impairment of Rights.
     -----------------------

     Other than pursuant to the provisions of Section E hereunder, the
Corporation will not, by amendment of the Articles of Incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of the Series B
Preferred Stock set forth herein, and will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may
be necessary or appropriate in order to protect the rights of the holders of the
Series B Preferred Stock against dilution or other impairment.

          C.  4% SERIES C CONVERTIBLE PREFERRED STOCK
              ---------------------------------------

1.   Dividends.
     ---------

     (a)  The holders of outstanding shares of Series C Preferred Stock shall be
entitled, in preference to the holders of any and all other classes of capital
stock of the Corporation (other than the Series A Preferred Stock, the Series B
Preferred Stock, and the Series D Preferred Stock, which will rank equally with
the Series C Preferred Stock as to dividends), to receive, out of any funds
legally available therefor, cumulative dividends on the Series C Preferred Stock
in cash, at the rate per annum of four percent (4%) of the Series C Base
Liquidation Amount (as defined in Section C.2 below), subject to proration for
partial years on the basis of a 365-day year ("Series C Cumulative Preference
Dividends").  Such dividends will accumulate commencing as of the date of
issuance of the Series C Preferred Stock and will be cumulative, to the extent
unpaid, whether or not they have been declared and whether or not there are
profits, surplus or other funds of the Corporation legally available for the
payment of dividends.  Accrued but unpaid dividends on the Series C Preferred
Stock shall be payable upon  conversion of the Series C Preferred Stock into
Class A Common Stock and Series D Preferred Stock.  Dividends paid in cash in an
amount less than the total amount of such dividends at the time accumulated and

                                       21
<PAGE>

payable on all outstanding shares of Series C Preferred Stock, including
fractions, shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. At any time when shares of Series C Preferred
Stock are outstanding and the Series C Cumulative Preference Dividends have not
been paid in full in cash: (i) no dividend whatsoever shall be paid or declared,
and no distribution shall be made, on any capital stock of the Corporation
ranking junior to the Series C Preferred Stock; and no shares of capital stock
of the Corporation ranking junior to the Series C Preferred Stock shall be
purchased, redeemed or acquired by the Corporation and no monies shall be paid
into or set aside or made available for a sinking fund for the purchase,
redemption or acquisition thereof. All numbers relating to the calculation of
dividends pursuant to this Section C.1 shall be subject to equitable adjustment
in the event of any stock split, combination, reorganization, recapitalization,
reclassification or other similar event involving a change in the Series C
Preferred Stock. At the time of the fifth anniversary following the initial sale
of the Series A Preferred Stock, the dividend rate on the Series C Preferred
Stock shall increase to 8% of the Series C Base Liquidation Amount per annum. On
the sixth anniversary date, the dividend rate on the Series C Preferred Stock
shall increase to 14% of the Series C Base Liquidation Amount per annum.

     (b)  Notwithstanding the foregoing, while any of the Senior Notes remain
outstanding, the Corporation shall not be permitted to pay any cash dividends
upon the Series C Preferred Stock (including any such dividends payable in
connection with a conversion of the Series C Preferred Stock) and the holders of
the Series C Preferred Stock shall not be entitled to receive any such
dividends, if and to the extent that such dividends would be prohibited by any
term or provision of the Indenture or any documents relating to any refinancing
of the Senior Notes; provided that the covenant under the caption "Restricted

Payments" in the Indenture, or any documents relating to any refinancing of the
Senior Notes, will not be materially more restrictive with regard to payments
than the restrictions set forth in the covenant under the caption "Certain
Covenants--Restricted Payments" in the Referenced Document, and provided further
                                                                ----------------
that no such amendment, supplement or modification of the Indenture, or any
documents relating to any refinancing of the Senior Notes, shall (i) increase
the aggregate principal amount of Senior Notes outstanding, (ii) be materially
more restrictive with regard to payments than the restrictions set forth in the
covenant under the caption "Certain Covenants--Restricted Payments" in the
Referenced Document or (iii) extend the maturity of the Senior Notes.  Any
change that will prohibit a payment that would otherwise be permitted pursuant
to the Referenced Document will be deemed material.

2.   Liquidation Preferences.
     -----------------------

     (a)  In the event of any distribution of assets upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, including
by consolidation, merger, share exchange or sale of all or substantially all of
the assets of the Corporation (in each case, an "Event of Dissolution"), each
holder of outstanding shares of Series C Preferred Stock shall be entitled to be
paid out of the assets of the Corporation available for distribution to
stockholders, whether such assets are capital, surplus, or earnings, and before
any amount shall be paid or distributed to the holders of  Class A Common Stock
or Class B Common Stock or of any other stock ranking on liquidation junior to
the Series C Preferred Stock (other than the Series A

                                       22
<PAGE>

Preferred Stock, the Series B Preferred Stock, and the Series D Preferred Stock,
which will rank equally with the Series C Preferred Stock in an Event of
Dissolution) an amount in cash equal to the greater of (i) the sum of (a) $4.472
per share (adjusted appropriately for stock splits, stock dividends,
recapitalizations and the like with respect to the Series C Preferred Stock),
plus (b) any accumulated but unpaid dividends to which such holder of
outstanding shares of Series C Preferred Stock is entitled pursuant to Section
C.1 hereof (the sum of (a) and (b) being referred to as the "Series C Base
Liquidation Amount") or (ii) the amount per share of Series C Preferred Stock
which the holders thereof would have received if all such shares had been
converted to Class A Common Stock and Series D Preferred Stock pursuant to
Sections C.5, C.6 or C.7 hereof immediately prior to such Event of Dissolution,
less any amount previously distributed on such shares in connection with such
Event of Dissolution; provided, however, that if, upon any Event of Dissolution,
                      --------  -------
the amounts payable with respect to the Series C Preferred Stock are not paid in
full, the holders of the Series C Preferred Stock shall share ratably in any
distribution of assets in proportion to the full respective preferential amounts
to which they are entitled.


     (b)  After full payment shall have been made to the holders of shares of
the Series C Preferred Stock (and Series A Preferred Stock, Series B Preferred
Stock and Series D Preferred Stock in accordance with Sections A.2, B.2 and D.2,
respectively), any balance of the assets of the Corporation then remaining shall
be allocated to the holders of shares of other classes of stock ranking junior
to the Series C Preferred Stock, including the holders of Class A Common Stock
and Class B Common Stock, in accordance with the respective interests therein.

3.   Voting Rights.
     -------------

     (a)  Except as otherwise expressly provided in these Amended and Restated
Articles of Incorporation, or as required by the FBCA, the holders of shares of
Series C Preferred Stock shall vote together with the holders of Class A Common
Stock, Class B Common Stock and Series A Preferred Stock as a single voting
group on all actions to be taken by the shareholders of the Corporation.  Each
share of Series C Preferred Stock shall entitle the holder thereof to such
number of votes per share on each such action as shall equal (i) the largest
number of whole shares of Class A Common Stock into which such shares of Series
C Preferred Stock could be converted, pursuant to the provisions of Sections
C.5, C.6 or C.7 hereof, multiplied by (ii) ten (10) at the record date for the
determination of shareholders entitled to vote on such matter or, if no such
record date is established, at the date such vote is taken or any written
consent of shareholders is solicited.

     (b)  Except as expressly provided herein or as required by law, as long as
20% or more of the greatest number of shares of Series C Preferred Stock issued
remain outstanding, the Corporation shall not, without the approval by vote or
written consent of the holders of at least 66 % of the outstanding shares of
Series C Preferred Stock; (i) authorize or issue any class or series of equity
securities having equal or superior rights to the Series C Preferred Stock as to
payment upon liquidation, dissolution or a winding up of the Corporation; (ii)
enter into any agreement that would restrict the Corporation's ability to
perform under any purchase agreement executed by the Corporation in connection
with an issuance of Series C Preferred Stock; (iii) amend its Articles of
Incorporation or Bylaws in any way which adversely affects the rights and

                                       23
<PAGE>

preferences of the holders of Series C Preferred Stock as a class; (iv) sell or
lease 20% or more of its assets, except in the ordinary course of business; (v)
issue additional securities to employees, officers or directors, except
securities issuable upon the exercise of options and warrants outstanding
immediately prior to the issuance of any Series C Preferred Stock, or issuable
upon the exercise of options granted in the future at fair market value; (vi)
issue any securities for a price less than fair market value, other than as may
be required by contractual commitments existing prior to the issuance of any
Series C Preferred Stock; or (vii) adopt any stock option plan other than the
Corporation's 1996 Stock Option Plan or increase the number of shares available
for issuance under such plan.

     (c)  The holders of the Series C Preferred Stock and Series A Preferred
Stock, voting together as a single class, shall be entitled to elect two-fifths
(2/5) of the number of directors on the Board of Directors of the Corporation.

4.   Redemption.
     ----------

     (a)  Commencing on the fifth anniversary of the initial sale of the Series
A Preferred Stock (the "Redemption Commencement Date"), the Corporation shall,
to the extent it may do so under applicable law, redeem all of the outstanding
shares of Series C Preferred Stock at a price equal to the Series C Base
Liquidation Amount at the time of redemption. Such redemption shall occur in two
payments, the first to occur on the Redemption Commencement Date and the second
to occur one (1) year thereafter (each a "Payment Date"). Each payment (a
"Redemption Payment") shall be in an amount equal to one-half of the Series C
Base Liquidation Amount calculated as of the date of such payment, with the
final Redemption Payment in an amount necessary to fully redeem all remaining
outstanding Series C Preferred Stock at a price equal to the Series C Base
Liquidation Amount.

     (b)  On each Payment Date, the Corporation shall redeem shares of Series C
Preferred Stock ratably from the holders thereof to the extent of the Redemption
Payment due on such date, according to the respective amounts which would be
payable with respect to the full number of Series C Preferred Stock to be
redeemed from them on such date, as if all such Series C Preferred Stock were
redeemed in full.  The Redemption Payment shall be payable in cash in
immediately available funds on the Payment Date.  Any outstanding shares of
Series C Preferred Stock not redeemed shall remain outstanding.  All shares of
Series C Preferred Stock which are to be redeemed hereunder shall remain issued
and outstanding until the Redemption Price therefor has been indefeasibly paid
in full in cash or has been deposited with an independent payment agent pursuant
to Section C.4(c).  Any Series C Preferred Stock which would otherwise be
redeemed on a Payment Date may be converted by the holder thereof to Class A
Common Stock and Series D Preferred Stock, in accordance with the provisions
hereof, at any time prior to the close of business on the last business day next
preceding such Payment Date.

     (c)  On or before the Redemption Commencement Date, the Corporation will
give written notice by mail, postage prepaid to the holders of record of Series
A Preferred Stock to be redeemed, such notice to be addressed to each such
holder at its post office address shown by the records of the Corporation,
specifying the place of such redemption; provided, however, that the

                                       24
<PAGE>

Corporation's failure to give such notice shall in no way affect its obligation
to redeem the shares of Series C Preferred Stock as provided in this Section
C.4.  If on or before a Payment Date, the funds necessary for satisfaction of
the Redemption Payment on such date shall have been deposited with an
independent payment agent so as to be, and continue to be, available for such
redemption, then, notwithstanding that any certificate for shares of Series C
Preferred Stock to be redeemed shall not have been surrendered for cancellation,
from and after the close of business on the Payment Date, the shares to be
redeemed as of such Payment Date shall no longer be deemed outstanding, any
dividends thereof shall cease to accrue, and all rights with respect to such
shares shall forthwith cease, except the conversion rights pursuant to Sections
C.5 and C.6, and the right of the holders thereof to receive, upon presentation
of the certificate representing shares so called for redemption, the Redemption
Payment applicable to such Series C Preferred Stock without interest thereon.

     (d)  If the funds of the Corporation legally available for redemption of
Series C Preferred Stock on a Payment Date are insufficient to pay the
Redemption Payment then due and to redeem the number of outstanding Series C
Preferred Stock to be redeemed on such Payment Date, the Corporation shall
redeem such shares of Series C Preferred Stock ratably from the holders thereof
to the extent of any funds legally available for redemption of such Series C
Preferred Stock, according to the respective amounts which would be payable with
respect to the full number of Series C Preferred Stock to be redeemed from them
on such date, as if all such Series C Preferred Stock were redeemed in full.  At
any time thereafter when additional funds of the Corporation are legally
available for the redemption of Series C Preferred Stock, such funds will be
used to redeem the balance of such Series C Preferred Stock which would have
otherwise been redeemed on such Payment Date, or such portion thereof for which
funds are then available, on the basis set forth above.

     (e)  Subsequent to the Redemption Commencement Date, until the full Series
C Base Liquidation Amount has been paid in cash for all outstanding shares of
Series C Preferred Stock: (A) no dividend whatsoever shall be paid or declared,
and no distribution shall be made, on any capital stock of the Corporation other
than shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock; and (B) no shares of capital stock
of the Corporation (other than the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or the Series D Preferred Stock) shall be
purchased, redeemed or acquired by the Corporation and no monies shall be paid
into or set aside or made available for a sinking fund for the purchase,
redemption or acquisition thereof.

     (f)  Upon receipt of the applicable Redemption Payment by certified check
or wire transfer, each holder of shares of Series C Preferred Stock to be
redeemed shall surrender the certificate or certificates representing such
shares to the Corporation, duly assigned or endorsed for transfer (or
accompanied by duly executed stock powers relating thereto), or shall deliver an
Affidavit of Loss with respect to such certificates at the principal executive
office or the Corporation or the office of the transfer agent for the Series C
Preferred Stock or such office or offices in the continental United States of an
agent for redemption as may from time to time be designated by notice to the
holders of Series C Preferred Stock and each surrendered certificate shall be
canceled and retired.

                                       25
<PAGE>

     (g)  All shares of Series C Preferred Stock acquired by the Corporation by
reason of redemption, purchase, conversion or otherwise shall be returned to the
status of authorized, unissued and undesignated shares of the Corporation's
preferred stock, and all such shares shall no longer be governed by this
Statement of Designation, Preferences, Rights and Limitations.  In addition,
upon the occurrence of (a) the redemption, purchase or conversion of all
outstanding shares of Series A Preferred Stock together with (b) the redemption,
purchase or conversion of all outstanding shares of Series B Preferred Stock,
all shares of Series C Preferred Stock of the Corporation shall be returned to
the status of authorized, unissued and undesignated shares of the Corporation's
preferred stock, and all such shares shall no longer be governed by this
Statement of Designation, Preferences, Rights and Limitations.

     (h)  Notwithstanding anything in this Section C.4. to the contrary, the
Corporation shall not be permitted to effect any redemption of the Series C
Preferred Stock, and no holder thereof shall have any right to have his or her
shares of Series C Preferred Stock redeemed by the Corporation, if at that time
such redemption is not permitted by the terms and provisions of the Indenture or
any refinancing thereof.

5.   Optional Conversion.
     -------------------

     (a)  Beginning on and at all times after the effective date of this Second
Amended and Restated Statement of Designation, Preferences, Rights and
Limitations, the holder of each single share of the outstanding Series C
Preferred Stock of the Corporation shall have the right to surrender the
certificate or certificates evidencing such share(s) and receive, in lieu and in
conversion thereof for each one (1) share of Series C Preferred Stock of the
Corporation so surrendered, a certificate evidencing (i) a number of shares of
Class A Common Stock of the Corporation equal to the quotient obtained by
dividing $4.472 by the then applicable Conversion Price, plus (ii) one (1) share
of Series D Preferred Stock of the Corporation.  The "Conversion Price" of the
Series C Preferred Stock is initially $4.472, subject to adjustment as provided
in Section C.7(a) hereof.  Fractional shares of Series C Preferred Stock may not
be surrendered.  Except as provided in Section C.1.(b) hereof, accumulated but
unpaid dividends on the shares of Series C Preferred Stock converted shall be
paid at the time of conversion, and such dividends are not convertible into
Class A Common Stock or Series D Preferred Stock.

     (b)  In the event the Corporation shall, at any time that any of the shares
of Series C Preferred Stock are outstanding, be consolidated with or merged into
any other corporation or corporations, or sell or lease all or substantially all
of its property and business as an entirety, then lawful provision shall be made
as part of the terms of such consolidation, merger, sale, or lease for the
holder of any shares of Series C Preferred Stock thereafter to receive in lieu
of such shares of Class A Common Stock and Series D Preferred Stock otherwise
issuable to him upon conversion of his shares of Series C Preferred Stock, but
at the Conversion Price which would otherwise be in effect at the time of
conversion as hereinbefore provided, the same kind and relative amount of
securities or assets as may be issuable, distributable, or payable upon such
consolidation, merger, sale or lease, with respect to shares of Class A Common
Stock of the Corporation.

                                       26
<PAGE>

     (c)  The Corporation need not issue fractional shares in satisfaction of
the conversion privilege of the shares of Series C Preferred Stock but, in lieu
of fractional shares, the Corporation at its option may make a cash settlement
in respect thereof equal to the purchase price of such Series C Preferred Stock,
as adjusted in accordance with Section C.7(a), multiplied by such fractional
share amount, or may issue scrip certificates exchangeable together with other
such scrip certificates aggregating one or more full shares for certificates
representing such full share or shares. Until the exchange thereof for
certificates representing full shares of Class A Common Stock and Series D
Preferred Stock, the holder of any such scrip certificates shall not be entitled
to receive dividends thereon, to vote with respect thereto, or to have any other
rights by virtue thereof as a shareholder of the Corporation, except such
rights, if any, as the Board of Directors may in its discretion determine in the
event of dissolution of the Corporation.

     (d)  The right of conversion of any holder of Series C Preferred Stock
shall be exercisable only if he or she provides thirty (30) days prior written
notice, by certified or registered mail, addressed to the attention of the
Secretary of the Corporation at the principal office of the Corporation, of his
or her intention to surrender shares of Series C Preferred Stock for conversion.
Such conversion notice shall state the number of shares of Series C Preferred
Stock to be converted.

     (e)  As promptly as practicable after the surrender for conversion of any
Series C Preferred Stock and considering the requirements for and in conformity
with all applicable laws, including, but not limited to, the Securities Act of
1933, as amended, the Corporation shall deliver or cause to be delivered at the
principal office of the Corporation (or such other places as may be designated
by the Corporation) to or upon the written order of the holder of such Series C
Preferred Stock, certificates representing the shares of Class A Common Stock
and Series D Preferred Stock, issuable upon such conversion, issued in such name
or names as such holder may direct.  Shares of the Series C Preferred Stock
shall be deemed to have been converted as of the close of business on the date
of the surrender of the Series C Preferred Stock for conversion and the rights
of the holders of such Series C Preferred Stock shall cease at such time, and
the person or persons in whose name or names the certificates for such surrender
are to be issued shall be treated for all purposes as having become the record
holder or holders of such Class A Common Stock and Series D Preferred Stock at
such time; provided, however, that if the surrender is on any date when the
stock transfer books of the Corporation shall be closed, the person or persons
in whose name or names the certificates for such shares are to be issued shall
be treated as the record holder or holders thereof for all purposes at the close
of business on the next succeeding day on which such stock transfer books are
open.

     (f)  The issuance of certificates for shares of Class A Common Stock and
Series D Preferred Stock upon conversion of the Series C Preferred Stock shall
be made without charge for any tax in respect of such issuance.  However, if any
certificate is to be issued in a name other than that of the holder of record of
the Series C Preferred Stock so converted, the person or persons requesting the
issuance thereof shall pay to the Corporation the amount of any tax which may be
payable in respect of any transfer involved in such issuance, or shall establish
to the satisfaction of the Corporation that such tax has been paid or is not due
and payable.

6.   Automatic Conversion.
     --------------------

     (a)  Each outstanding share of Series C Preferred Stock shall automatically
be converted into (i) a number of shares of Class A Common Stock equal to the
quotient obtained by dividing $4.472 by the then applicable Conversion Price,
plus (ii) one (1) share of Series D Preferred Stock, immediately upon the first
to occur of either of the following events (each, an "Automatic Conversion
Event"): (A) the authorization of such conversion, including without limitation
in an action by written consent in accordance with Section 607.0704, Florida
Statutes, as amended from time to time, by the holders of not less than two-
thirds (66 %) of all of the then issued and outstanding shares of Series C
Preferred Stock, or (B) the consummation by the Corporation of a Qualified
Public Offering.

     (b)  On or after the date of an occurrence of an Automatic Conversion
Event, and in any event within ten (10) days after receipt of notice, by mail,
postage prepaid from the Corporation of the occurrence of such event, each
holder of record of shares of Series C Preferred Stock shall surrender such
holder's certificates evidencing such shares at the principal office of the
Corporation or at such other place as the Corporation shall designate, and shall
thereupon be entitled to receive certificates evidencing the number of shares of
Class A Common Stock and Series D Preferred Stock into which such shares of
Series A Preferred Stock are converted. Notwithstanding any other provisions
herein to the contrary, on the date of the occurrence of an Automatic Conversion
Event, each holder of record of the shares of Series C Preferred Stock shall be
deemed to be the holder of record of the Class A Common Stock and Series D
Preferred Stock issuable upon such conversion and no shares of Series C
Preferred Stock shall be considered outstanding notwithstanding that the
certificates representing such shares of Series C Preferred Stock shall not have
been surrendered at the office of the Corporation, that notice from the
Corporation shall not have been received by any holder of record of shares of
Series C Preferred Stock, or that the certificates evidencing such shares of
Class A Common Stock and Series D Preferred Stock shall not then be actually
delivered to such holder; provided, however, that the Corporation shall not be
obligated to issue certificates evidencing the shares of Class A Common Stock
and Series D Preferred Stock issuable upon such conversion unless certificates
evidencing such shares of the Series C Preferred Stock being converted are
either delivered to the Corporation or its transfer agent, or the holder
notifies the Corporation or its transfer agent that such certificates have been
lost, stolen or destroyed and executes an agreement satisfactory to the
Corporation to indemnify the Corporation from any loss incurred by it in
connection therewith.

7.   Provisions Relating to Automatic and Optional Conversions.
     ---------------------------------------------------------

     (a)  Adjustments to Conversion Price.
          -------------------------------

          (i)  Subdivision, Combination or Reclassification of Class A Common
               --------------------------------------------------------------
               Stock.
               -----

               (A)  If the Corporation shall, while there are any shares of
                    Series C Preferred Stock issued and outstanding, effect a
                    subdivision of its shares of Common Stock into a greater
                    number of such shares or a combination of such shares into a
                    lesser number of shares, whether

                                       28
<PAGE>

                    by forward or reverse stock split, stock dividend (payable
                    in shares of Common Stock) or otherwise, the Conversion
                    Price shall be proportionally increased or reduced, as the
                    case may be, to reflect the effectuation of such subdivision
                    or combination.

               (B)  If the Corporation shall, while there are any shares of
                    Series C Preferred Stock issued and outstanding, effect a
                    capital reorganization or reclassification of the Common
                    Stock or any distribution by the Corporation to holders of
                    Class A Common Stock, whether in the form of stock, debt
                    securities, or other assets or property of the Corporation,
                    (each, an "Adjustment Event"), then, as a condition of such
                    Adjustment Event, lawful and adequate provision shall be
                    made whereby the holders of the Series C Preferred Stock
                    shall thereafter have the right to acquire and receive upon
                    conversion of the Series C Preferred Stock such shares of
                    stock, securities, assets or property as would have been
                    issuable or payable as a result of such Adjustment Event
                    with respect to or in exchange for such number of
                    outstanding shares of the Class A Common Stock as would have
                    been received as if such Series C Preferred Stock were
                    converted  immediately prior to the consummation of such
                    Adjustment Event.

               (C)  In the event that an Adjustment Event shall occur by means
                    of a merger, consolidation, combination, share exchange, or
                    sale or lease of all or substantially all the assets of the
                    Corporation, then as a condition of such Adjustment Event,
                    lawful and adequate provision shall be made whereby the
                    holders of the Series C Preferred Stock shall thereafter
                    have the rights to acquire and receive upon conversion of
                    their shares of Series C Preferred Stock, such shares of
                    stock,  securities or assets as would have been issuable or
                    payable as part of such Adjustment Event with respect to or
                    in exchange for such number of outstanding shares of the
                    Class A Common Stock as would have been received upon
                    conversion of the Series C Preferred Stock (in all
                    instances) immediately before such Adjustment Event, and in
                    any such case appropriate provisions shall be made with
                    respect to the rights and interests of the holders of the
                    Series C Preferred Stock such that the provisions hereof
                    (including without limitation provisions for adjustments of
                    the Conversion Price and of the number of shares of Class A
                    Common Stock acquirable and receivable upon the conversion
                    of the Series C Preferred Stock) shall thereafter be
                    applicable, in relation to any shares of stock, securities
                    or assets thereafter deliverable upon the conversion of the
                    Series C Preferred Stock (including an immediate adjustment,
                    by reason of such Adjustment Event of the Series C Preferred
                    Stock to the value for

                                       29
<PAGE>

                    the Class A Common Stock reflected by the terms of such
                    Adjustment Event if the value so reflected is less than the
                    Conversion Price in effect immediately prior to such
                    Adjustment Event). In the event of an Adjustment Event as a
                    result of which a number of shares of Common Stock of the
                    surviving or purchasing corporation is greater or lesser
                    than the number of shares of Common Stock of the Corporation
                    outstanding immediately prior to such Adjustment Event, then
                    the Conversion Price in effect immediately prior to such
                    Adjustment Event shall be adjusted in the same manner as
                    though there were a subdivision or combination of the
                    outstanding shares of Class A Common Stock of the
                    Corporation. The Corporation will not effect any such
                    Adjustment Event unless prior to the consummation thereof
                    the successor corporation (if other than the Corporation)
                    resulting from such consolidation or merger or the purchase
                    or lease of such assets shall assume by written instrument
                    mailed or delivered to the holders of the Series C Preferred
                    Stock at the last address of each such holder appearing on
                    the books of the Corporation, the obligation to deliver to
                    each such holder such shares of stock, securities or assets

                    may be entitled.

          (ii) Issuance of Common Stock.  Except as provided in Sections
               ------------------------
               C.7(a)(iii) and C.7(a)(iv), if and whenever the Corporation shall
               issue or sell, or shall in accordance with subparagraphs (A)
               through (F), inclusive, of Section C.7(a)(iii) be deemed to have
               issued or sold, any shares of its Class A Common Stock, or
               options, warrants or other rights to purchase Class A Common
               Stock or securities convertible into Class A Common Stock, for a
               consideration per share less than the Conversion Price in effect
               immediately prior to the time of such issuance or sale, then
               forthwith upon such issuance or sale, the Conversion Price shall,
               subject to subparagraphs (A) to (F) of Section C.7(a)(iii), be
               reduced to:

               (A)  For issuances or sales on or before 18 months after the date
                    of the first issuance of Series A Preferred Stock, the
                    Conversion Price shall equal such issuance or sale price.

               (B)  For issuances or sales after 18 months from the date of the
                    first issuance of Series A Preferred Stock, the Conversion
                    Price shall be determined by multiplying the Conversion
                    Price in effect immediately prior to such issuance or sale
                    by a fraction; the numerator of which shall be (1) the
                    number of shares of Class A Common Stock outstanding
                    immediately prior to the issuance of such additional shares
                    of Class A Common Stock, plus (2) the number of shares of
                    Class A Common Stock which the net

                    aggregate consideration, if any, received by the Corporation
                    for the total number of such additional shares of Class A
                    Common Stock so issued would purchase at the Conversion
                    Price in effect immediately prior to such issuance, and; the
                    denominator of which shall be (1) the number of shares of
                    Class A Common Stock outstanding immediately prior to the
                    issuance of such additional shares of Class A Common Stock
                    plus (2) the number of such additional shares of Class A
                    Common Stock so issued.

          (iii) For purposes of determining the adjusted Conversion Price under
                Section C.7(a)(ii)(A) and (B), the following subsections (A) to
                (F), inclusive, shall be applicable:

                (A) Issuance of Rights or Options.  Except as provided Section
                    -----------------------------
                    C.7(a)(iv), in case at any time the Corporation shall in any
                    manner grant (whether directly or by assumption in a merger
                    or otherwise) any rights to subscribe for or to purchase, or
                    any options for the purchase of, Class A Common Stock or any
                    stock or other securities convertible into or exchangeable
                    for Class A Common Stock (such rights or options being
                    herein called "Options" and such convertible or exchangeable
                    stock or securities being herein called "Convertible
                    Securities") whether or not such Options or the right to
                    convert or exchange any such Convertible Securities are
                    immediately exercisable, and the price per share for which
                    such Class A Common Stock is issuable upon the exercise of
                    such Options or upon conversion or exchange of such
                    Convertible Securities (determined by dividing (x) the total
                    amount, if any, received or receivable by the Corporation as

                    to the Corporation upon the exercise of all such Options,

                    Convertible Securities, the minimum aggregate amount of
                    additional consideration, if any, payable upon the issue or
                    sale of such Convertible Securities and upon the conversion
                    or exchange thereof, by (y) the total maximum number of
                    shares of Class A Common Stock issuable upon the exercise of
                    such Options) shall be less than the Conversion Price in
                    effect immediately prior to the time of the granting of such
                    Option, then the total maximum number of shares of Class A
                    Common Stock issuable upon the exercise of such Options or

                    such Options shall (as of the date of granting of such
                    Options) be deemed to be outstanding and to have been issued
                    by the Corporation for such price per share.  No adjustment
                    of the Conversion Price shall be made upon

                    the actual issuance of such Convertible Securities except as
                    otherwise provided in subsection (C) below.

               (B)  Issuance of Convertible Securities.  In case the Corporation
                    ----------------------------------
                    shall in any manner issue (whether directly or by assumption
                    in a merger or otherwise) or sell any Convertible
                    Securities, whether or not the rights to exchange or convert
                    thereunder are immediately exercisable, and the price per
                    share for which such Class A Common Stock is issuable upon
                    such conversion or exchange (determined by dividing (x) the

                    number of shares of Class A Common Stock issuable upon the
                    conversion or exchange of all such Convertible Securities)
                    shall be less than the Conversion Price in effect
                    immediately prior to the time of such issuance or sale, then
                    the total maximum number of all such Convertible Securities
                    shall (as of the date of the issue or sale of such
                    Convertible Securities) be deemed to be outstanding and to
                    have been issued and sold by the Corporation for such price
                    per share, provided that, except as otherwise specified in
                    subsection (C) below, no adjustment of the Conversion Price
                    shall be made upon the actual issue of such Class A Common
                    Stock upon exercise of any Options for which adjustments of
                    the Conversion Price have been or are to be made pursuant to
                    other provisions of this Section C.7(a) and no further
                    adjustment of the Conversion Price shall be made by reason
                    of such issuance or sale.

               (C)  Change in Option Price or Conversion Rate.  If the purchase
                    -----------------------------------------
                    price provided for in any Option referred to in subparagraph
                    (A), the additional consideration, if any, payable upon the
                    conversion or exchange of any Convertible Securities
                    referred to in subparagraphs (A) or (B), or the rate at
                    which any Convertible Securities referred to in
                    subparagraphs (A) or (B) are convertible into or
                    exchangeable for Class A Common Stock, shall change at any
                    time (other than under or by reason of provisions designed
                    to protect against dilution of the type set forth in Section
                    C.7(a)), the Conversion Price in effect at the time of such
                    change shall forthwith be readjusted to the Conversion Price
                    which would have been in effect at such time had such
                    Options or Convertible Securities still outstanding provided
                    for such changed purchase price, additional consideration,
                    or conversion rate, as the case may be, at the time
                    initially granted, issued or sold.  If the purchase price
                    provided for in any Option referred to in subsection (A), or

                    the rate at which any Convertible Securities referred to in
                    subparagraphs (A) or (B) are convertible into or
                    exchangeable for Class A Common Stock, shall be reduced at
                    any time under or by reason or provisions with respect
                    thereto designed to protect against dilution, then in case
                    of the delivery of Class A Common Stock upon the exercise of
                    any such Option or upon conversion or exchange of any such
                    Convertible Security, the Conversion Price then in effect
                    hereunder shall forthwith be adjusted to such respective
                    amount as would have been obtained had such Option or
                    Convertible Security never been issued as to such Class A
                    Common Stock and had adjustments been made upon the issuance
                    of the shares of Class A Common Stock delivered as
                    aforesaid, but only if as a result of such adjustment the
                    Conversion Price then in effect hereunder is hereby reduced.

               (D)  Treatment of Expired Options and Unexercised Convertible
                    --------------------------------------------------------
                    Securities.  On the expiration of any Option or the
                    ----------
                    termination of any right to convert or exchange any
                    Convertible Securities, the Conversion Price then in effect
                    hereunder shall forthwith be increased to the Conversion
                    Price which would have been in effect at the time of such
                    expiration or termination had such Option or Convertible
                    Securities, to the extent outstanding immediately prior to
                    such expiration or termination, never been issued.

               (E)  Integral Transaction.  In case any Options shall be issued
                    --------------------
                    in connection with the issue or sale of other securities of
                    the Corporation, together comprising one integral
                    transaction in which no specific consideration is allocated
                    to such Options by the parties thereto, such Options shall
                    be deemed to have been issued without consideration.

               (F)  Consideration for Stock.  In case any shares of Class A
                    -----------------------
                    Common Stock, Options or Convertible Securities shall be
                    issued or sold or deemed to have been issued or sold for
                    cash, the consideration received therefor shall be deemed to
                    be the amount received by the Corporation therefor.  In case
                    any shares of Class A Common Stock, Options, or Convertible
                    Securities shall be issued or sold for a consideration other
                    than cash, the amount of the consideration other than cash
                    received by the Corporation shall be the fair value of such
                    consideration.  In case any shares of Class A Common Stock,
                    Options, or Convertible Securities shall be issued in
                    connection with any merger in which the Corporation is the
                    surviving corporation, the amount of consideration therefor
                    shall be deemed to be the fair value of such portion of the
                    net assets and business of the non-surviving corporation as
                    shall be attributable to

                                       33
<PAGE>

                    such Class A Common Stock, Options, or Convertible
                    Securities, as the case may be. In the event of any
                    consolidation or merger of the Corporation in which the
                    Corporation is not the surviving corporation, or, in the
                    event of any sale of all or substantially all of the assets
                    of the Corporation for stock or other securities of any
                    corporation, this subsection shall be applied in the same
                    manner as if the Corporation had been the surviving
                    corporation in such consolidation or merger, or the
                    purchasing corporation in such sale of assets; and for
                    purposes of this sentence the Corporation shall be deemed:

                    (1)  to have issued and sold a number of shares of its Class
                         A Common Stock, Options, or Convertible Securities
                         equal to the sum of (x) the number of shares of the
                         Corporation's Class A Common Stock actually
                         outstanding, (y) the number of shares of the
                         Corporation's Class A Common Stock acquirable upon the
                         exercise of all outstanding Options, and (z) the number
                         of shares of the Corporation's Class A Common Stock
                         acquirable upon conversion of all outstanding
                         Convertible Securities, which those persons who were
                         security holders of the surviving corporation
                         immediately before the consummation of the transaction
                         would have received in exchange for the common stock,
                         options, and convertible securities of the surviving
                         corporation held by them immediately after consummation
                         of the transaction, based on the exchange ratio on
                         which the transaction was consummated (i.e., the
                         inverse of the ratio pursuant to which the
                         Corporation's Class A Common Stock were exchangeable
                         into the surviving corporation's securities) and
                         assuming that Corporation had been the surviving
                         corporation; and

                    (2)  to have received in exchange therefor a consideration
                         equal to the fair market value (immediately before the
                         consummation of such transaction) of the assets (less
                         the liabilities) of the surviving corporation; and if
                         the application of this sentence results in adjustment
                         of the Conversion Price and number of Conversion Shares
                         issuable upon conversion of the Series C Preferred
                         Stock, then the determination of the Conversion Price
                         and the number of Conversion Shares issuable upon
                         conversion of the Series C Preferred Stock immediately
                         prior to such merger, consolidation, or sale shall be
                         made after giving effect to the adjustment set forth
                         herein.  If the stock of the surviving or purchasing
                         corporation in such a transaction is

                                       34

                         publicly traded, the market value of such corporation's
                         outstanding stock immediately before consummation of
                         the exchange shall be presumptive evidence of the fair
                         market value of its assets (less liabilities).

          (iv) Notwithstanding anything in Section C.7 to the contrary, no
               adjustment shall be made to the Conversion Price upon (w) the
               issuance of any shares of Class A Common Stock, options or
               Convertible Securities in connection with an acquisition by the
               Corporation or a merger in which the Corporation is the surviving
               corporation, calculated on a fully diluted basis and further
               provided such issuance is to the sellers of the acquired entity
               or assets or security of the merged entity and is made for fair
               value and the Board of Directors of the Corporation determines
               that the acquisition or merger is in the best interests of the
               Corporation and its stockholders; (x) the issuance of any shares
               of Class A Common Stock upon conversion of any shares of Series C
               Preferred Stock; (y) the issuance of Class A Common Stock upon
               the exercise of any options, warrants or other rights to purchase
               Class A Common Stock outstanding on the date of the first
               issuance of Series A Preferred Stock, including the warrant to be
               issued to Alex. Brown & Sons Incorporated in connection with the
               initial sale of Series A Preferred Stock or (z) the future
               issuance of Class A Common Stock or warrants, options or rights
               to purchase such Class A Common Stock to employees, consultants,
               directors or vendors directly or pursuant to plans approved by
               the Board of Directors so long as such options are granted at
               fair market value.

     (b)  The Corporation shall at all times reserve and keep available out of
its authorized but unissued shares of Class A Common Stock solely for the
purpose of effecting the conversion of the shares of Series C Preferred Stock
pursuant to Sections C.5 and C.6 hereof, such number of its shares of Class A
Common Stock and Series D Preferred Stock as shall from time to time be
sufficient to effect such conversion of all outstanding shares of the Series C
Preferred Stock; and, if at any time the number of authorized but unissued
shares of Class A Common Stock or Series D Preferred Stock shall not be
sufficient to effect the conversion of all of the then outstanding shares of
Series C Preferred Stock, the Corporation will take such corporate action as
may, in the opinion of its counsel be necessary to increase its authorized but
unissued shares of Class A Common Stock or Series D Preferred Stock to such
number of shares as shall be sufficient for such purposes.

8.   Preemptive Rights.
     -----------------

     (a)  At any time after the first closing of the sale of the Series A
Preferred Stock but prior to the filing of effective registration statement
relating to a Qualified Public Offering, or from time to time prior thereto, if
the Corporation shall issue, grant or sell any of its equity securities, the
Corporation shall, in each such case, offer a pro rata share of any such
issuance, grant or sale to the holders of Series A Preferred Stock and Series C
Preferred Stock. If any

                                       35
<PAGE>

holders of Series A Preferred Stock or Series C Preferred Stock determine not to
accept their pro rata share, then the other Series A Preferred Stock holders and
Series C Preferred Stockholders shall be given the right to accept such share on
a pro rata basis.

     (b)  Notwithstanding the foregoing, the preemptive rights set forth in
Section C.8(a) shall not apply in the event of any issue, grant or sale in
connection with (i) a merger, consolidation, combination, share exchange or sale
or lease of all or substantially all assets of the Corporation or another
corporation; (ii) conversion of Series C Preferred Stock pursuant to Sections
C.5 or C.6 hereof; (iii) the exercise of options, warrants or other rights to
purchase stock outstanding prior to the issuance of any Series C Preferred
Stock; (iv) any stock option or other employee benefit plans of the Corporation
and (v) the grant or exercise of a warrant to purchase Class A Common Stock
issued to Alex. Brown & Sons Incorporated in connection with the initial sale of
Series A Preferred Stock.  In any event, all preemptive rights shall expire and
be of no further force and effect upon the effectiveness of a registration
statement relating to a Qualified Public Offering.

9.   No Impairment of Rights.
     -----------------------

     Other than pursuant to the provisions of Section E hereunder, the
Corporation will not, by amendment of the Articles of Incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of the Series C
Preferred Stock set forth herein, and will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may
be necessary or appropriate in order to protect the rights of the holders of the
Series C Preferred Stock against dilution or other impairment.  Without limiting
the generality of the foregoing, other than pursuant to the provisions of
Section E hereunder, the Corporation (i) will not increase the par value of any
shares of stock receivable on the conversion of the Series C Preferred Stock
above the amount payable therefor on such conversion, and (ii) will take all
such action as may be necessary or appropriate in order that the Corporation may
validly and legally issue fully paid and non-assessable shares of stock on the
conversion of all Series C Preferred Stock under the terms hereof from time to
time outstanding.

10.  Issuance of Series C Preferred Stock.
     ------------------------------------

     The Series C Preferred Stock shall only be issued in connection with the
consummation of the Series A Convertible Preferred Stock Purchase Agreement
dated as of March 6, 1997, among the Corporation and the Purchasers named
therein.

          D.   4% SERIES D REDEEMABLE PREFERRED STOCK
               --------------------------------------

1.   Dividends.
     ---------

     (a)  The holders of outstanding shares of Series D Preferred Stock shall be
entitled, in preference to the holders of any and all other classes of capital
stock of the Corporation (other than the Series A Preferred Stock, Series B
Preferred Stock, and Series C Preferred Stock, which will rank equally with the
Series D Preferred Stock as to dividends), to receive, out of any funds

                                       36
<PAGE>

legally available therefor, cumulative dividends on the Series D Preferred Stock
in cash, at the rate per annum of four percent (4%) of the Series D Base
Liquidation Amount (as defined in Section D.2 below), subject to proration for
partial years on the basis of a 365-day year ("Series D Cumulative Preference
Dividends").  Such dividends will accumulate commencing as of the date of
issuance of the Series D Preferred Stock and will be cumulative, to the extent
unpaid, whether or not they have been declared and whether or not there are
profits, surplus or other funds of the Corporation legally available for the
payment of dividends.  Series D Cumulative Preference Dividends shall become due
and payable with respect to any share of Series D Preferred Stock as provided in
Section D.2 and Section D.4.  Dividends paid in cash in an amount less than the
total amount of such dividends at the time accumulated and payable on all
outstanding shares of Series D Preferred Stock, including fractions, shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding.  At any time when shares of Series D Preferred Stock are
outstanding and the Series D Cumulative Preference Dividends have not been paid
in full in cash: (i) no dividend whatsoever shall be paid or declared, and no
distribution shall be made, on any capital stock of the Corporation ranking
junior to the Series D Preferred Stock; and no shares of capital stock of the
Corporation ranking junior to the Series D Preferred Stock shall be purchased,
redeemed or acquired by the Corporation and no monies shall be paid into or set
aside or made available for a sinking fund for the purchase, redemption or
acquisition thereof.  All numbers relating to the calculation of dividends
pursuant to this Section D.1 shall be subject to equitable adjustment in the
event of any stock split, combination, reorganization, recapitalization,
reclassification or other similar event involving a change in the Series D
Preferred Stock.  At the time of the fifth anniversary following the initial
sale of the Series A Preferred Stock, the dividend on the Series D Preferred
Stock shall increase to 8% of the Series D Base Liquidation Amount per annum.
At the time of the sixth anniversary following the initial sale of the Series A
Preferred Stock, the dividend rate on the Series D Preferred Stock shall
increase to 14% of the Series D Base Liquidation Amount per annum.

     (b)  Notwithstanding the foregoing, while any of the Senior Notes remain
outstanding, the Corporation shall not be permitted to pay any cash dividends
upon the Series D Preferred Stock (including any such dividends payable in
connection with a conversion of the Series D Preferred Stock) and the holders of
the Series D Preferred Stock shall not be entitled to receive any such
dividends, if and to the extent that such dividends would be prohibited by any
term or provision of Indenture or any documents relating to any refinancing of
the Senior Notes; provided that the covenant under the caption "Restricted
Payments" in the Indenture, or any documents relating to any refinancing of the
Senior Notes, will not be materially more restrictive with regard to payments
than the restrictions set forth in the covenant under the caption "Certain
Covenants--Restricted Payments" in the Referenced Document, and provided further
that no such amendment, supplement or modification of the Indenture, or any
documents relating to any refinancing of the Senior Notes, shall (i) increase
the aggregate principal amount of Senior Notes outstanding, (ii) be materially
more restrictive with regard to payments than the restrictions set forth in the
covenant under the caption "Certain Covenants--Restricted Payments" in the
Referenced Document or (iii) extend the maturity of the Senior Notes. Any change
that will prohibit a payment that would otherwise be permitted pursuant to the
Referenced Document will be deemed material.

<PAGE>

2.   Liquidation Preferences.
     -----------------------

     (a)  Upon any Event of Dissolution, each holder of an outstanding share of
Series D Preferred Stock shall be entitled to be paid out of the assets of the
Corporation available for distribution to stockholders, whether such assets are
capital, surplus, or earnings as follows, and before any amount shall be paid or
distributed to the holders of Class A Common Stock or Class B Common Stock or of
any other stock ranking on liquidation junior to the Series D Preferred Stock
(other than the Series A Preferred Stock, the Series B Preferred Stock, and the
Series C Preferred Stock, which will rank equally with the Series D Preferred
Stock in an Event of Dissolution) an amount in cash equal to the sum of (a)
$4.472 per share (adjusted appropriately for stock splits, stock dividends,
recapitalizations and the like with respect to the Series D Preferred Stock),
plus (b) any accumulated but unpaid dividends to which such holder of
outstanding shares of Series D Preferred Stock is entitled pursuant to Section
D.1 hereof (the sum of (a) and (b) being referred to as the "Series D Base
Liquidation Amount"); provided, however, that if, upon any Event of Dissolution,
                      --------  -------
the amounts payable with respect to the Series D Preferred Stock are not paid in
full, the holders of the Series D Preferred Stock shall share ratably in any
distribution of assets in proportion to the full respective preferential amounts
to which they are entitled.

     (b)  After full payment shall have been made to the holders of shares of
the Series D Preferred Stock (and Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock in accordance with Sections A.2, B.2 and
C.2), any balance of the assets of the Corporation then remaining shall be
allocated to the holders of shares of other classes of stock ranking junior to
the Series D Preferred Stock, including the holders of Class A Common Stock and
Class B Common Stock, in accordance with the respective interests therein.

3.   Voting Rights.
     -------------

     The holders of Series D Preferred Stock shall not be entitled to vote on
any matters except those contemplated by Section E and to the extent otherwise
required under the FBCA.

4.   Redemption.
     ----------

     (a)  The Corporation shall redeem the Series D Preferred Stock as follows:

          (i)  The Corporation shall, upon consummation of a Qualified Public
               Offering, to the extent it may do so under applicable law and to
               the extent it may do so under Section D.4(a)(ii), redeem all of
               the outstanding shares of Series D Preferred Stock at a price
               equal to the Series D Base Liquidation Amount as of the date of
               such consummation.  For redemptions required under this Section
               D.4(a)(i), the "Payment Date" shall be the date of consummation
               of a Qualified Public Offering, and the "Redemption Payment"
               shall be the aggregate Series D Base Liquidation Amount.

          (ii) The managing underwriter of the Qualified Public Offering shall
               have the right to limit the redemption of all or any part of the
               Series D Preferred

                                       38
<PAGE>

                 Stock then outstanding. In such event, the part of the Series D
                 Preferred Stock not redeemed shall automatically convert into a
                 three year obligation (the "Obligation") payable to the holder
                 thereof in the principal amount of the Series D Base
                 Liquidation Amount. Principal and interest on each Obligation
                 shall be payable quarterly, with interest at the rate of 2%
                 over the Prime Rate during the first year, 4% over the Prime
                 Rate during the second year, and 6% over the Prime Rate during
                 the third year after issuance. "Prime Rate" shall mean the
                 prime rate reported from time to time in The Wall Street
                 Journal, initially on the date the Series B Preferred Stock
                 converts into the Obligation, and each anniversary thereafter.
                 In the event that any quarterly payment on the Obligations is
                 not paid when due, the interest rate applicable over the
                 remaining life of the Obligations shall be increased to 6% over
                 the Prime Rate.

          (iii)  Commencing on the fifth anniversary of the initial sale of the
                 Series A Preferred Stock, the Corporation shall, to the extent
                 it may do so under applicable law, redeem all of the
                 outstanding shares of Series D Preferred Stock at a price equal
                 to the Series D Base Liquidation Amount at the time of
                 redemption.

     (b)  Any redemption under Section D.4(a)(iii) shall occur in two payments,
the first to occur on the Redemption Commencement Date and the second to occur
one (1) year thereafter (each a "Payment Date"). Each payment (a "Redemption
Payment") shall be in an amount equal to one-half of the Series D Base
Liquidation Amount calculated as of the date of such payment, with the final
Redemption Payment in an amount necessary to fully redeem all remaining
outstanding Series D Preferred Stock at a price equal to the Series D Base
Liquidation Amount.

     (c)  On each Payment Date, the Corporation shall redeem shares of Series D
Preferred Stock ratably from the holders thereof to the extent of the Redemption
Payment due on such date, according to the respective amounts which would be
payable with respect to the full number of Series D Preferred Stock to be
redeemed from them on such date, as if all such Series D Preferred Stock were
redeemed in full. The Redemption Payment shall be payable in cash in immediately
available funds on the Payment Date. Any outstanding shares of Series D
Preferred Stock not redeemed shall remain outstanding. All shares of Series D
Preferred Stock which are to be redeemed hereunder shall remain issued and
outstanding until the Redemption Price therefor has been indefeasibly paid in
full in cash or has been deposited with an independent payment agent pursuant to
Section D.4(d).

     (d)  On or before the Redemption Commencement Date, the Corporation will
give written notice by mail, postage prepaid to the holders of record of Series
D Preferred Stock to be redeemed under Section D.4(a), such notice to be
addressed to each such holder at its post office address shown by the records of
the Corporation, specifying the place of such redemption; provided, however,
that the Corporation's failure to give such notice shall in no way affect its
obligation to redeem the shares of Series D Preferred Stock as provided in this
Section D.4. If on or before a Payment Date, the funds necessary for
satisfaction of the Redemption Payment under

                                       39
<PAGE>

Section D.4(a) on such date shall have been deposited with an independent
payment agent so as to be, and continue to be, available for such redemption,
then, notwithstanding that any certificate for shares of Series D Preferred
Stock to be redeemed shall not have been surrendered for cancellation, from and
after the close of business on the Payment Date, the shares to be redeemed as of
such Payment Date shall no longer be deemed outstanding, any dividends thereof
shall cease to accrue, and all rights with respect to such shares shall
forthwith cease, except the right of the holders thereof to receive, upon
presentation of the certificate representing shares so called for redemption,
the Redemption Payment applicable to such Series D Preferred Stock without
interest thereon.

     (e)  If the funds of the Corporation legally available for redemption of
Series D Preferred Stock on the Payment Date are insufficient to pay the
Redemption Payment then due and to redeem the number of outstanding Series D
Preferred Stock to be redeemed on such Payment Date, the Corporation shall
redeem such shares of Series D Preferred Stock ratably from the holders thereof
to the extent of any funds legally available for redemption of such Series D
Preferred Stock, according to the respective amounts which would be payable with
respect to the full number of Series D Preferred Stock to be redeemed from them
on such date, as if all such Series D Preferred Stock were redeemed in full. At
any time thereafter when additional funds of the Corporation are legally
available for the redemption of Series D Preferred Stock, such funds will be
used to redeem the balance of such Series D Preferred Stock, which would have
otherwise been redeemed on such Payment Date, or such portion thereof for which
funds are then available, on the basis set forth above.

     (f)  Subsequent to the Redemption Commencement Date, until the full Series
D Base Liquidation Amount has been paid in cash for all outstanding shares of
Series B Preferred Stock: (A) no dividend whatsoever shall be paid or declared,
and no distribution shall be made, on any capital stock of the Corporation other
than shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, and Series D Preferred Stock; and (B) no shares of capital
stock of the Corporation (other than the Series A Preferred Stock, the Series B
Preferred Stock, the Series C Preferred Stock and the Series D Preferred Stock)
shall be purchased, redeemed or acquired by the Corporation and no monies shall
be paid into or set aside or made available for a sinking fund for the purchase,
redemption or acquisition thereof.

     (g)  Upon receipt of the applicable Redemption Payment by certified check
or wire transfer, each holder of shares of Series D Preferred Stock to be
redeemed shall surrender the certificate or certificates representing such
shares to the Corporation, duly assigned or endorsed for transfer (or
accompanied by duly executed stock powers relating thereto), or shall deliver an
Affidavit of Loss with respect to such certificates at the principal executive
office or the Corporation or the office of the transfer agent for the Series D
Preferred Stock or such office or offices in the continental United States of an
agent for redemption as may from time to time be designated by notice to the
holders of Series D Preferred Stock and each surrendered certificate shall be
canceled and retired.

     (h)  All shares of Series D Preferred Stock acquired by the Corporation by
reason of redemption, purchase, conversion or otherwise shall be returned to the
status of authorized,

                                       40
<PAGE>

unissued and undesignated shares of the Corporation's preferred stock, and all
such shares shall no longer be governed by this Statement of Designation,
Preferences, Rights and Limitations. In addition, upon the occurrence of (a) the
redemption, purchase or conversion of all outstanding shares of Series A
Preferred Stock together with (b) the redemption, purchase or conversion of all
outstanding shares of Series B Preferred Stock, all shares of Series D Preferred
Stock of the Corporation shall be deemed to be authorized, unissued and
undesignated shares of the Corporation's preferred stock, and all such shares
shall no longer be governed by this Statement of Designation, Preferences,
Rights and Limitations.

     (i)  Notwithstanding anything in this Section D.4. to the contrary, the
Corporation shall not be permitted to effect any redemption of the Series D
Preferred Stock, and no holder thereof shall have any right to have his or her
shares of Series D Preferred Stock redeemed by the Corporation, if at that time
such redemption is not permitted by the terms and provisions of the Indenture or
any refinancing thereof.

5.   No Impairment of Rights.
     -----------------------

     Other than pursuant to the provisions of Section E hereunder, the
Corporation will not, by amendment of the Articles of Incorporation or through
any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of the Series D
Preferred Stock set forth herein, and will at all times in good faith assist in
the carrying out of all such terms and in the taking of all such actions as may
be necessary or appropriate in order to protect the rights of the holders of the
Series D Preferred Stock against dilution or other impairment.

6.   Issuance of Series D Preferred Stock.
     ------------------------------------

     The Series D Preferred Stock shall only be issued in connection with the
consummation of the Series A Convertible Preferred Stock Purchase Agreement
dated as of March 6, 1997, among the Corporation and the Purchasers named
therein.

E.   AMENDMENT OF RIGHTS, DESIGNATIONS AND PREFERENCES HEREUNDER.
     -----------------------------------------------------------

     The holders of at least 66 2/3% of the then outstanding Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock voting together as a single class, shall have the authority to bind the
holders of all of the then outstanding shares of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock

waiver of any of the rights and preferences afforded to such holders hereunder.

          ----------------------------------------------

Ladies and Gentlemen:

     In connection with the registration of shares of Class A Common Stock of
the company, par value $.01 per share (the "Shares"), consisting of 13,269,231
Shares offered by the Company under the Securities Act of 1933, as amended (the
"Act"), by SBA Communications Corporation, a Florida corporation (the
"Company"), on Form S-1 filed with the Securities and Exchange Commission (the
"Commission") on April 19, 1999 (File No. 333-76547), as amended by Amendment
No. 1 filed with the Commission on May 7, 1999 (collectively, the "Registration
Statement"), you have requested our opinion with respect to the matters set
forth below.

     In our capacity as your special Florida counsel in connection with such
registration, we are familiar with the proceedings taking and proposed to be
taken by the Company in connection with the authorization, issuance and sale of
the Shares, and for the purposes of this opinion, have assumed such proceedings
will be timely completed in the manner presently proposed. In addition, we have
made such legal and factual examinations and inquiries, including an examination
of originals or copies certified or otherwise identified to our satisfaction of
such documents, corporate records and instruments, as we have deemed necessary
or appropriate for purposes of this opinion.

     In our examination, we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, and the conformity
to authentic original documents of all documents submitted to us as copies.
<PAGE>

     We are opining herein as to the effect on the subject transaction only of
the internal laws of the State of Florida, and we express no opinion with
respect to the applicability thereto, or the effect thereon, of the laws of any
other jurisdiction or as to any matters of municipal law or the laws of any
local agencies within any state.

     Subject to the foregoing, it is our opinion that the Shares have been duly
authorized and upon issuance, delivery and payment therefor in the manner
contemplated by the Registration Statement, will be, validly issued, fully paid
and nonassessable.

     We consent to your filing this opinion as an exhibit to the Registration
Statement and to the reference to our firm contained under the heading "Legal
Matters."

                              Very truly yours,

      3.01 Engagement of Vendor. (a) Subject to the provisions of Article 9,
BellSouth hereby engages Vendor to acquire the Sites, construct and install the

applicable Project Schedule. Vendor shall perform and be responsible for all
responsibilities assigned to Vendor in the Vendor Responsibility Matrix attached

            (b) Except as set forth in the following sentence and in Article 7,
Vendor's entire compensation for the Project or any part thereof will be derived
solely from the payments of rent by BellSouth for each Site, pursuant to the
terms of the Master Lease and the applicable Site Lease. In the event that
BellSouth withdraws a Site from this Agreement for any reason except in
connection with Section 4.02(e) or 13.05(a), BellSouth shall pay Vendor for all
of Vendor's reasonable out-of-pocket costs directly incurred, to the date of
withdrawal, in connection with such Site ("Withdrawal Costs"), including,
without limitation, reasonable third party vendor costs plus a fee to cover
overhead and employee time equal to ten percent (10%) of the amount of any
Withdrawal Costs; provided that Vendor has provided BellSouth with
substantiation of such Withdrawal Costs in reasonable detail.

      3.02 Term. (a) The term of this Agreement shall commence on the Effective
Date, and shall continue until the Project Completion Date, unless sooner

Completed as of that date, BellSouth, in its sole discretion, may extend the
term hereof as to all or any of the Sites that have not been Completed, until
the Completion thereof.

            (b) Notwithstanding anything to the contrary contained herein, the
parties acknowledge and agree that, upon Completion of any Site and the

survive the expiration or termination hereof, Article 9, Annex D, the Master
Lease, the applicable Site Lease and related documents shall govern the
respective rights and obligations of the parties with respect to each such Site.

      3.03 Time for Commencement and Completion. Vendor and BellSouth
acknowledge that the time for Scheduled Commencement Date and Completion of the
Project will be determined by the Project Schedule. Vendor's unexcused failure

Liquidated Damages pursuant to Section 11.01.

performing its obligations hereunder, and the parties agree to cooperate with
each other in Completing the Project in accordance with this Agreement.
BellSouth and Vendor, in the performance of this Agreement, will be acting in
their respective individual capacities and not as employees, partners, joint
venturers, agents or associates of one another. In the performance of this
Agreement, Vendor is, and shall at all times during the term of this Agreement
be, an independent contractor. Nothing contained in this Agreement creates the
relationship of a joint venture, partnership, association or agency between the
parties. No party shall have any authority to bind or otherwise obligate the
other. Persons retained by either party as employees or agents shall not, solely
by reason thereof, be deemed to be employees or agents of the other party.

otherwise engaged in the Project to be properly licensed and legally qualified

contractors and subcontractors. Vendor and BellSouth will each ensure that
anything related to its employees, agents, consultants, advisors, contractors or
subcontractors shall be in strict compliance with Governmental Requirements,
except for noncompliances which would not have a Material Adverse Effect.

           (d) BellSouth reserves the right to require from Vendor the
immediate removal from or to exclude any Person or entity employed by or working
for Vendor from any Site, in BellSouth's judgment, but only if the exercise
thereof is a commercially reasonable procedure under the circumstances, who in
BellSouth's opinion (i) engages in any misconduct, (ii) is incompetant or (iii)
is negligent in the performance of its, his or her duties. Vendor shall be
responsible for any additional labor costs arising in connection with the
removal requested pursuant to this Section 3.05(d).

and agrees that Neil Wiser, as General Manager of Vendor's Mid-Atlantic Region,
will devote time and attention to matters not related to the Project, and (ii)
Vendor shall not remove any Key Employee from any such position or reassign any
such Key Employee, either within the Project or to another project, without the
prior written consent of BellSouth, such consent not to be unreasonably
withheld.

     3.06  Familiarity with Project and Sites. Vendor represents and warrants
that Vendor is familiar with the Project and Specifications applicable to the
Towers and Improvements, has visited and examined, or will visit and examine,
each Site and the surrounding locale, and knows or will know the working

standards applied by Vendor prior to the date of this Agreement.

afforded access to all of Vendor's records, books, correspondence, instructions,
drawings, plans, blueprints, specifications, receipts, vouchers, memoranda and
similar data relating to the Project and this Agreement to the extent relating

structural integrity of the Improvements, or if BellSouth otherwise provides
reasonable justification therefor, except for privileged documents or where
disclosure is prohibited by law. Such books and records shall be open for
inspection and copying upon reasonable written notice by BellSouth, at its cost,

obligated to accept any Additional Site listed as a part of Region One on Part
II of Annex A (the "Rejected Additional Site"), and (ii) be obligated to perform
any Services with respect to such Rejected Additional Site. Such notice shall
specify those potential cell sites which, upon BellSouth's selection pursuant to
Section 5.03, would constitute Additional Sites for purposes of this Agreement.
If the sites are not set forth in Part II of Annex A, Vendor shall have thirty
(30) days from receipt of such written notice to provide a written approval or
rejection of such sites. Vendor's failure to respond within such thirty (30) day
period as to any such sites shall be deemed a rejection by Vendor of such sites.
If Vendor rejects any such sites or is deemed to have rejected any such sites,
such sites shall not be Additional Sites and shall not be part of the Project.
Upon BellSouth's giving of such written notice, Vendor shall extend the
performance of its obligations hereunder to any sites that become the Additional
Sites. The parties shall adopt a Project Schedule as to such Additional Sites,
so as to facilitate Completion of all Additional Sites, without affecting the
Project Schedule as to the Original Sites. Vendor acknowledges and agrees that
if it constructs a tower and improvements similar to Towers and Improvements
hereunder on any site, after Vendor has received notice that such Site is in a
search area designated by BellSouth on any site, prior to an election by
BellSouth pursuant to this Section 3.09 for Vendor to include such site in the
Project, such site shall, at BellSouth's election, be subject to the terms of
this Agreement for all purposes. If BellSouth makes any such election as to any
such site, Vendor shall make such site available to BellSouth as though it were
an Additional Site, on the same terms and conditions as are set forth herein and
in the Master Lease, it being understood and agreed that BellSouth or other
Anchor Tenant shall be the anchor tenant of such site, notwithstanding any
agreement Vendor may have entered into with any Other Tenant. Vendor shall cause
any such tower and improvements to comply with all the requirements hereunder
for Towers and Improvements.

     3.10  Available Sites in Event of Condemnation. If, prior to the execution
of a Site Lease for a Site, any condemnation occurs as to any Site as
contemplated by Section 20(b) of the Master Lease, Vendor shall, at the request
of BellSouth or the applicable Anchor Tenant, perform all its obligations
hereunder in respect of a replacement site for such condemned Site, satisfactory
to BellSouth, as if such replacement site were an Original Site hereunder,
including without limitation the proposal of potential cell site locations
pursuant to Section 5.03, the construction of a Tower and Improvements on any
selected Site pursuant to and in accordance with Article 6 and the leasing of
such Site to the applicable Anchor Tenant pursuant to the Master Lease and a
Site Lease, provided that the monthly rent payable in respect of such
replacement Site shall be the monthly Rent that would have been payable in
respect of the replaced Site. The Site Schedule, Scheduled Commencement Date and
Scheduled Completion Date for any such replacement site shall be determined by
Vendor and BellSouth consistently with the construction schedules set forth in
this Agreement. This Agreement shall survive the completion of the Project
indefinitely to the extent necessary to give effect to this Section 3.10.

any Site is required by applicable law, Vendor shall provide BellSouth with
written notice setting forth such belief and requesting BellSouth's approval of
such disclosure to any Governmental Authority specified therein, and BellSouth
shall provide Vendor with its approval or disapproval of such disclosure within
five (5) Business Days of BellSouth's receipt of Vendor's notice. If BellSouth
fails to respond within such five (5) Business Day period, BellSouth will be
deemed to have rejected Vendor's request. In such event or if BellSouth provides
its disapproval within such five (5) Business Day period, Vendor shall be
prohibited from disclosing BellSouth's relationship to such Site or the Project
to any Governmental Authority, provided, however, that the Scheduled
Commencement Date, the Project Completion Date, the Site Schedule and the
Project Schedule, in each case only with respect to the applicable Site, shall
be adjusted by Vendor and BellSouth to the extent of any delays caused by the
failure of BellSouth to permit such disclosure.

           (d) Vendor shall use its best efforts to obtain any Permits
necessary to commence construction of the Towers and the Improvements on or
before the Scheduled Commencement Date with respect to each Site, including
without limitation the approval of any necessary rezoning of such Site, grant of
any variance, vacating of any right-of-way, issuance of any order or other
action that may be necessary, or approve any other land use approval necessary,
to commence construction of the Tower and Improvements on such Site. If, despite
such efforts, any Permits required to be obtained before commencement of
construction have not been obtained or could not have been obtained as of the
Scheduled Commencement Date, then Vendor shall continue to exercise its best
efforts to obtain any such Permits as promptly as possible, and the Scheduled
Commencement Date, the Site Schedule, the Project Schedule and the Project
Completion Date, in each case as it applies to such Site, shall be adjusted by
Vendor and BellSouth, as may be commercially reasonable to reflect any
additional time period necessary for obtaining such Permits, and such additional
time shall be deemed to be an Excusable Delay. Notwithstanding the foregoing, if
(i) Vendor (x) fails to obtain any such Permits within six (6) months after the
applicable Scheduled Commencement Date without giving effect to any adjustment
or (y) spends more than $25,000 in costs, fees and expenses (including
reasonable attorneys' fees and expenses) in pursuing Permits for any Site, and
(ii) BellSouth has not exercised its rights under Section 4.02(e), then Vendor
will have the right to cease using its best efforts to obtain such Permits,
exercisable by giving BellSouth written notice thereof. Not later than ten (10)
days after receiving such notice, BellSouth shall give Vendor notice of its
election of a right under clause (i), (ii) or (iii) of Section 4.02(e) in
respect of such Site. If BellSouth fails to give notice as to any such election,
such Site shall be deemed to be

rejected by BellSouth pursuant to Section 4.02(e)(iii), and Vendor shall propose
to BellSouth an alternative cell site pursuant to Section 5.03.

           (e) If Vendor has not obtained any Permit required for the
Construction of the Tower or any Site and Improvements or Intended Use thereof
(other than as to installation of BellSouth's Improvements), by the applicable
Scheduled Commencement Date, then, at any time after such Scheduled Commencement
Date, BellSouth's sole remedy shall be, at BellSouth's sole option, to (i)
assume responsibility for obtaining such Permit by written notice to Vendor, and
Vendor shall reimburse BellSouth for any costs, fees, or expenses (including
reasonable attorneys' fees and expenses) incurred in pursuing and obtaining such
Permit, to the extent such costs and expenses (including amounts spent by Vendor
in pursuing Permits for such Site) do not exceed $25,000; provided that any
costs, fees and expenses in excess of $25,000 may be incurred upon mutual
agreement of the parties, in which case BellSouth and Vendor shall each pay 50%
of such excess, (ii) reject the Site at no cost or expense to BellSouth,
whereupon such Site shall no longer be a part of the Project or (iii) reject the
Site and cause Vendor to propose additional potential cell sites as
alternatives, in accordance with Section 5.03.

           (f) Vendor shall comply with all Governmental Requirements in
performing its obligations under this Agreement, the Master Lease and each Site
Lease, except where the failure to comply could not have a Material Adverse
Effect. Vendor shall indemnify, and hold harmless, each BellSouth Indemnitee
from and against any Claims (including without limitation any fine, penalty or
damage) arising out of Vendor's failure to comply with any Governmental
Requirements including, without limitation, zoning laws and FAA regulations,
unless such failure arises from BellSouth's willful or negligent conduct.

           (g) In the event that (i) BellSouth elects to exercise its rights
under Section 4.02(e)(i) or (iii) above, or (ii) any Site is deemed to be
rejected by BellSouth pursuant to the last sentence of Section 4.02(d), the
Scheduled Commencement Date, the Site Schedule, the Project Schedule and the
Project Completion Date, in each case as it applies to such Site, shall be
adjusted by Vendor and BellSouth, as may be commercially reasonable to reflect
any additional time period necessary for obtaining Permits or acquisition of a
new Site.

(i) reflected in the implementation of the Project Schedule for such Site, (ii)
coordinated with the implementation of the Project Schedule for the other Sites
in its Cluster and (iii) consistent with the Project Schedule.

     5.02  Due Diligence. Vendor shall, through one or more qualified
consultants: (i) compile and review all existing data with respect to each Site
from a seller or lessor of such Site and any and all Governmental Authorities
having jurisdiction thereof, and any other Persons who may have relevant
information necessary to develop each Site; (ii) cause to be performed any and
all analyses, examinations, investigations, tests and inspections of each Site,
including, but not limited to, environmental studies, surveys, geo-technical
studies, soil borings and the like and cause to be accurately completed and
returned to BellSouth with respect to each Site, the Site Data Package attached

Governmental Authorities and Persons who will furnish electric power, telephone
service or any other utility to each Site as to any matters which may affect or
be necessary to the Development of each Site; (iv) determine all Governmental
Requirements necessary for the Development of each Site, including, but not
limited to, the Tower and Improvements, zoning laws or regulations. Vendor shall
perform or supervise the activities described in items (i) through (iv) above,
and, upon BellSouth's request, shall deliver to BellSouth copies of written
reports, memoranda or material correspondence prepared for Vendor with respect
to the foregoing.

     5.03  Proposal of Cell Sites. Subject to Section 5.01, from time to time
Vendor shall propose to BellSouth three (3) potential cell site locations for a
Site within each search area set forth in Annex A, in accordance with the
Project Schedule, unless Vendor can demonstrate to BellSouth's reasonable
satisfaction that three (3) such potential sites do not exist in such area,
gives BellSouth an officer's certificate to such effect, duly executed by an
authorized officer of Vendor, and proposes as many potential cell site locations
as comply with the requirements of the next succeeding sentence. Vendor shall
not propose any such potential cell site unless it reasonably believes that such
site meets the requirements of this Agreement for a Site in all material
respects. If none of the sites proposed by Vendor for any search area meets such
requirements, Vendor shall continue proposing additional potential cell sites,
until one becomes a Site hereunder, unless Vendor can demonstrate to BellSouth's
reasonable satisfaction that no such site is available and gives BellSouth an
officer's certificate to such effect, duly executed by an authorized officer of
Vendor. Not later than five (5) Business Days after receipt of any such proposal
as to any potential cell site, BellSouth shall notify Vendor as to which (if
any) of such proposed cell sites it views in its judgment as acceptable,
whereupon such cell sites shall become Sites for all purposes of this Agreement.
BellSouth's selection of any proposed cell site as a Site shall not relieve or
release Vendor from performing any of its obligations hereunder in respect of
such Site, or otherwise affect any of Vendor's obligations hereunder. Promptly
following BellSouth's selection of any such Site, BellSouth shall deliver to
Vendor a Notice to Proceed for such Site.

     5.04  Utilities. Vendor shall negotiate with the electric utility company
servicing each Site a plan for the provision of service to such Site required
for the Intended Use of the Site.

Vendor shall make application for such electric utility company to furnish
service to such Site as may be adequate for the Intended Use and the use and
enjoyment of the Site by all Other Tenants that may exist from time to time.
Vendor shall cause such electric utility company to provide connection to such
Site. In the case of telephone company connection facilities, all obligations
remain with the Vendor to effect connections required for the Intended Use of
the Site, with the exception that the Vendor shall utilize BellSouth as their
agent to work with the local telephone company on the development of the
servicing plan. Annex C sets forth additional details of electric utility and
telephone company connections.

     6.01  General. (a) The parties shall hold progress meetings, and Vendor
shall submit progress reports to BellSouth, in accordance with the
implementation of the Project Schedule or otherwise on a weekly, bi-weekly or
monthly basis as may be agreed between parties. Progress reports will show for
each Site, at a minimum, and not by way of limitation, all dates and schedules
referred to in the Project Schedule and the applicable Site Schedule, any
anticipated delays, other relevant information, and the corresponding activity
period. The progress reports shall also show the progress of all Sites included
in each Cluster. In addition, BellSouth may request and Vendor shall facilitate
progress meetings with Vendor's key managers and subcontractors, including the
establishment of oversight committees to monitor specific work in progress on
Sites at times and locations agreed upon by BellSouth and Vendor in writing no
less than seven days prior to such meetings. Progress reports shall be for
planning purposes and monitoring compliance with this Agreement.

           (b) Should any information or approval be required from BellSouth as
Work progresses, Vendor shall request such information or approval in writing.
Said requests shall be submitted sufficiently in advance of the date upon which
the information or approval is needed, but in no event less than five (5) days
in advance of such date unless Vendor becomes aware of such required information
or approval in less than such 5-day period, to permit BellSouth to act without
affecting the progress or sequence of the Work. Such request shall provide a
reasonable time for a response by BellSouth.

           (c) Vendor shall, on a periodic basis (but not less frequently than
weekly), review the progress of the construction, evaluate the percentage of
completion of each Site and its Cluster as indicated in the Project Schedule and
the applicable Site Schedule and review such percentages with BellSouth. The
construction schedule report shall be distributed not less than weekly during
the construction phase of the Project, indicating the actual progress compared
to the scheduled progress of the Work in accordance with the applicable Site
Schedule, the schedules for all Sites in the applicable Cluster and the Project
Schedule. The reports shall compare the actual construction dates to scheduled
construction dates for each Site and the Cluster.

           (d) Notwithstanding anything to the contrary in this Agreement,
Vendor's obligation to keep BellSouth informed on the status of the Project
under this Agreement, including, without limitation, progress meetings, progress
reports, establishment of oversight committees and construction schedule
reports, shall be managed to the extent directed by the BellSouth local market.

     6.02  Performance of the Work. Vendor shall have the responsibility and
obligation to perform the Work in accordance with Annex D. Vendor shall provide
a management team or a representative on each Site to provide supervision and
administration of the Completion of the Work for each such Site. Vendor shall
establish and implement coordination and communication procedures between Vendor
and BellSouth. Vendor shall establish and implement procedures for reviewing and
processing requests for clarifications and interpretations of the
Specifications, including, without limitation, drawings and technical
specifications, schedule adjustments; and such other procedures as may be
required to Complete the Project.

     6.03  [reserved]

     6.04  Site and Project Schedules. (a) To enable the Towers and the
Improvements to be planned, scheduled and Completed in an orderly and
expeditious manner, Vendor acknowledges and agrees that each Site Schedule shall
be consistent with the Specifications and the implementation of each stage of
the Project Schedule.

           (b) Upon the occurrence of an Excusable Delay, the Site Schedule for
any affected Site, the Project Schedule, the Scheduled Commencement Date and the
Project Completion Date, each only as they apply to the affected Site, shall be
adjusted to reflect any additional time which will be required for the
performance of any of the duties or obligations of Vendor under this Agreement
as a result of such event, provided that the extent of such adjustment shall be
subject to the prior written approval of BellSouth, which approval shall not be
unreasonably withheld or delayed.

           (c) Except as set forth in Section 6.04(b) as to an individual Site,
neither the Site Schedule for any Site nor the Project Schedule shall change,
and Vendor will have no right to cause any such change, without prior written
approval by BellSouth. Within five (5) Business Days per Site after the receipt
of any request from Vendor for a change to any Site Schedule or the Project
Schedule, BellSouth shall notify Vendor in writing of its approval or
disapproval of such proposed change. Failure of BellSouth to respond within said
five (5) Business Day period shall constitute and be deemed an approval of such
requested change unless the change is, or results in, an extension of the
Scheduled Completion Date with respect to any Site, any other Site in the
Cluster in which such Site is located, or the Project, in which case BellSouth's
failure to respond within such five (5) Business Day period shall constitute and
be deemed a disapproval.

           (d) Vendor acknowledges and agrees that it has an affirmative
obligation and responsibility promptly to notify BellSouth of any circumstance
which affects or may affect any Site Schedule in any material respect or the
Project Schedule and the extent to which it is anticipated such Site Schedule or
the Project Schedule may be affected as a result of such circumstance.

     6.05  Quality Review. Vendor shall establish and implement a program to
monitor the quality of the construction during the implementation of the Project
Schedule. The purpose of the program shall be to assist in guarding against
defects and deficiency in the Work. At any time and from time to time BellSouth
may in its discretion, and without need to demonstrate cause, conduct an
independent program to monitor the quality of the construction and Vendor's
compliance with its obligations hereunder.

     6.06  Compliance with Requirements, Permits, Bonds and Insurance during
Construction. Vendor shall comply with all Environmental, Health and Safety
Requirements as they relate to the construction of the Towers and the
Improvements in connection with the Project, except for noncompliances that have
not had and are not reasonably likely to have a Material Adverse Effect. Vendor
shall, at its own cost and expense, procure and maintain all licenses and
Permits required by local, state or federal regulatory agencies and authorities
with respect to the construction, and shall comply with all local, state and
federal laws, ordinances, rules and regulations applicable to this Agreement,
except for failures that have not had and are not reasonably likely to have a
Material Adverse Effect. If, notwithstanding Vendor's diligent efforts, Vendor
experiences any delays in obtaining any license or Permit related to the
construction phase of the Project on time, such delay shall constitute an
Excusable Delay and shall be subject to Section 6.04(b). Vendor shall indemnify
and hold harmless each of the BellSouth Indemnitees from and against any fine,
penalty or damage arising out of the failure by Vendor, its Affiliates or any of
their respective employees, agents, contractors, subcontractors, advisors or
consultants to comply with any such laws, ordinances, rules or regulations
including, without limitation, zoning laws and FAA regulations, unless such
failure arises from BellSouth's or the Carolina Partnership's willful or
negligent conduct. Vendor shall obtain, or cause to be obtained, all bonds and
insurance, including without limitation the insurance required under Article 10,
which are consistent with sound commercial practices in Vendor's industry for
the commencement of construction and Completion of the Work with respect to each
Site.

     6.07  Work Permits. Vendor shall be the applicant for any and all necessary
work Permits, except as BellSouth may otherwise consent pursuant to Section
4.02(c). Vendor shall coordinate and manage all professional and technical
services required in connection with the preparation and filing of applications
for and obtaining all Permits. Vendor shall be responsible for ensuring that all
applications for the Permits are diligently prepared and filed, and pursued and
obtained.

     6.08  Construction. (a) Vendor, at Vendor's sole cost and expense, shall
cause the Towers and the Improvements to be constructed and installed diligently

with the industry standard workmanship and materials, in accordance with the
Specifications, the implementation of the Project Schedule for each Site and all
applicable laws. BellSouth will have the right to approve or reject the quality
of all materials, equipment and systems to be used in the Completion of the
Towers and Improvements if such materials, equipment or systems do not comply
with the Specifications or are not commercially suitable for the Intended Use.
Vendor shall supervise the work and activities of the contractors,
subcontractors, engineers and other Persons engaged in the design, development,
construction and installation of the Towers and Improvements. Vendor shall
obtain, or cause to be obtained, all warranties. Vendor shall cause (i) the
construction of a Tower and other Improvements on each Site in accordance with
the applicable Site Schedule subject to Vendor's rights under Section 7.01 and
(ii) the Completion of the Project to occur on or before the Project Completion
Date.

           (b) If BellSouth requests changes to any Specifications, Vendor
shall promptly make such changes to the Specifications and, the parties shall
adjust the Scheduled Commencement Date, the Site Schedule, the Project Schedule
and the Project Completion Date, in each case as it applies to the affected
Site, as may be necessary or required, and such adjustment shall be an Excusable
Delay, subject to BellSouth's reimbursement of Vendor for all reasonable
out-of-pocket costs incurred by Vendor in making such changes, and subject to
such changes not reducing the multi-tenant colocation capability of the Tower.

      6.09 Project Data. In performing Services hereunder, Vendor shall compile
data concerning the Project and furnish such data to BellSouth, all in
accordance with the procedures set forth in Annex F.

      6.10 Warranty. Vendor does hereby warrant and guarantee that the Tower and
Improvements on each Site and all workmanship and materials incorporated therein
will be constructed in accordance with the Specifications and will be free from
defects in workmanship for a period of twelve (12) months commencing on the
Completion Date for such Site (the "Warranty Period"). At BellSouth's request,
Vendor shall assign to BellSouth a non-exclusive right to enforce all warranties
respecting materials used by Vendor in Completing the Project and shall secure
any and all consents from the suppliers of such materials to make such
assignment effective or enforce any such warranties on behalf of BellSouth. If
any defect or deviation should exist, develop, be discovered or appear within
the Warranty Period, Vendor, at its sole cost and expense, immediately upon
demand, shall fully and completely repair, correct and eliminate such defect or
deviation. The foregoing warranties and guarantees are cumulative of and in
addition to, and not restrictive of or in lieu of, any and all other warranties
and guarantees provided for or required by the Specifications, any other
provision of this Agreement or applicable laws, and shall survive the expiration
or termination of this Agreement.

      6.11 Access and Inspection. (a) The construction shall be performed in
such a manner as will permit BellSouth to inspect each Site. BellSouth may, at
its election, conduct such inspections as it deems necessary at each Site, upon
reasonable notice to Vendor, and provided that BellSouth shall not delay, hinder
or interfere with performance of construction. If

BellSouth notifies Vendor of any observed defects or nonconformities with the
Specifications, Vendor shall promptly correct any defect or nonconformity in
such time and manner as will permit Completion of each Site or Sites in
accordance with the Site Schedule and the Project Schedule. The failure of
BellSouth to inspect any Site or Sites, however, will not in any way limit,
waive, or otherwise affect the rights of BellSouth with respect to any of
Vendor's warranties or obligations under this Agreement.

            (b) BellSouth will, upon reasonable notice to Vendor, have access to
any Site during all working hours, and will have the right to observe the Work
performed; provided, however, that BellSouth shall not delay, hinder or
interfere with the performance of the Work. BellSouth's inspection of any Work
will not relieve Vendor of any of its obligations to perform the Work in
accordance with this Agreement, including without limitation the Specifications,
except to the extent a specific deviation from the Specifications at any Site is
or has been accepted in writing by BellSouth. Work found not to be in accordance
with the Specifications shall be replaced or re-performed by Vendor, except to
the extent a specific deviation from the Specifications is or has been accepted
in writing by BellSouth. BellSouth will have the right to reject materials and
workmanship which are defective or not in conformance with the Specifications.
Rejected Work at any Site must be promptly removed from such Site. Failure on
the part of BellSouth to reject defective or nonconforming Work will not be
construed to imply an acceptance of such Work; provided, however, to the extent
a specific deviation from the Specifications is or has been accepted in writing
by BellSouth, such deviation shall not be deemed to be defective or
nonconforming Work.

            (c) Should BellSouth consider it necessary or advisable at any time
before Completion to examine Work already completed therein, Vendor shall, on
request of BellSouth, promptly furnish all necessary facilities, labor, and
material for that purpose. If such Work is found to be defective in any material
respect, Vendor shall pay all expenses of such examination. If, however, such
Work is not found to be defective in any material respect, BellSouth shall pay
all expenses of such examination and restoration of the Work. Any delays caused
by BellSouth's incorrect assessment that any Work is defective shall constitute
an Excusable Delay and be subject to Section 6.04(b).

            (d) BellSouth shall have a non-exclusive right and easement to
access each Site on a twenty-four (24) hour, seven (7) day per week basis, on
foot or motor vehicles, for the purposes of inspecting the construction on such
Site. BellSouth may, upon written notice to Vendor at least twenty-four (24)
hours before entering any Site, access such Site and climb the Tower, provided
that if such entry is necessary, required or advisable in respect of an
emergency, no prior written notice shall be required. Only authorized employees,
contractors, subcontractors, engineers, agents or representatives of BellSouth
will be permitted to enter any Site. BellSouth agrees that any employee,
contractor, subcontractor, engineer, representative or agent directed or
permitted by BellSouth to enter any Site will be covered by the insurance
described in Article 10.

      6.12 Completion. (a) Promptly following the Completion of the Work at any
Site in accordance with the requirements of the Specifications and the
requirements of this Agreement, including without limitation the construction of
the Tower and the Improvements on such Site and the performance of the final
cleanup thereon, Vendor shall notify BellSouth in writing of its good faith
belief that such Site is Completed. The parties shall execute a Completion
Certificate with respect to such Site as soon as reasonably practicable after
BellSouth receives such notification, provided, that BellSouth shall not
unreasonably withhold or delay execution of the Completion Certificate with
respect to such Site.

           (b) In addition to any right BellSouth may have under Section 6.11,
BellSouth will have the right to (i) inspect any Site at any time after
BellSouth receives the notification under Section 6.12(a) and prior to any date
on which the Completion Certificate is executed and (ii) notify Vendor in
writing if such inspection by BellSouth reveals that Completion has not occurred
with respect to any Site or Sites. Promptly after receipt of any such
notification, Vendor shall promptly cause any unperformed Work to be performed.

      7.01 Identification of Colocation Sites. For those Sites in respect of
which Vendor has not entered into a Ground Lease as of the date of this
Agreement, BellSouth shall notify SBA within five (5) business days after the
date of this Agreement or simultaneously with the submission of an Additional
Site, of any known existing cell sites in such search area that would be
suitable for the colocation of BellSouth's Improvements, consistent with the
requirements of Annex I ("Potential Colocation Sites"), including without
limitation sites that would be available by virtue of existing contractual
arrangements to which BellSouth is a party ("Existing Colocation Arrangements").
BellSouth shall identify the location of such Potential Colocation Site and
specify whether or not the lessor of such Potential Colocation Site is a party
to an Existing Colocation Arrangement. BellSouth acknowledges that Vendor
maintains a preference to fulfill BellSouth's needs for wireless communications
towers as to the Sites via suitable colocation sites that may be available
within the search areas, and consequently, Vendor shall use good faith efforts
to maximize colocation opportunities. BellSouth agrees to accept any colocation
opportunity (including Potential Colocation Sites and Existing Colocation
Arrangements) presented by Vendor so long as the rent is consistent with the
rent payable for BellSouth's other colocations for similar sites and such

the lease and the proposed colocation for any Potential Colocation Site are
acceptable to BellSouth, upon approval of such terms and conditions by
BellSouth, as evidenced by BellSouth's execution of a site lease therefor, such
Potential Colocation Site shall become a Site for purposes of this Agreement,
shall be added to the scope of the Project and shall be covered by the Project
Schedule. Thereafter Vendor shall perform such other Colocation Services (as
defined in Annex I) as BellSouth may direct, in accordance with this Agreement.

                                  SITE MATTERS

      8.01 Site Acquisition. In order to permit the construction and
installation of the Tower and the Improvements on each Site, SBA Towers shall
acquire either fee simple title to, or a leasehold interest in, each Site. Each
Site in which SBA Towers acquires either a fee simple title or a leasehold
interest shall be free and clear of all Liens other than Permitted Liens. Except
as set forth in Schedule 8.01, the Ground Lease for each Site in which SBA
Towers acquires a leasehold interest shall be substantially in the form attached
hereto as Exhibit C, except for Colocation Sites; provided that Ground Leases
for Colocation Sites shall be subject to BellSouth's prior written approval, not
to be unreasonably withheld, prior to such site becoming a Colocation Site.

      8.02 Vendor's Inspection of Site Prior to Scheduled Commencement Date.
Vendor shall not effect the Acquisition of any Site unless, prior to the
Acquisition Date, Vendor and its agents, employees, consultants, contractors and
subcontractors, have entered such Site and conducted such due diligence,
examinations, investigations, tests and inspections ("Inspections") with respect
to such Site as are customary in the industry, together with such other
Inspections as Vendor customarily performs or are necessary or advisable under
the circumstances and Vendor finds the results of such Inspections to be
satisfactory. In the event that Vendor determines, in Vendor's reasonable
judgment, that the results of such Inspections are not satisfactory, Vendor
shall give BellSouth notice to such effect and thereafter such site shall no
longer be a Site hereunder and Vendor shall identify and propose to BellSouth a
new potential cell site location for a Site pursuant to and subject to Sections
5.01 and 5.03 hereof, and the Site Schedule, the Scheduled Commencement Date,
the Project Schedule and the Project Completion Date, each as they apply to the
applicable Site, shall be adjusted to reflect any additional time which will be
required for the performance of any of the duties or obligations of Vendor under
this Agreement as a result of such event, as an Excusable Delay.

      8.03 Hazardous Waste and Contamination Investigation. (a) Prior to the
Acquisition Date for any Site, Vendor shall cause the Environmental Assessment

BellSouth with copies of all such Environmental Assessments.

           (b) Within five (5) Business Days after discovery of any
environmental condition on any Site not disclosed by, or in excess of the
conditions disclosed by, the Environmental Assessment, Vendor shall advise
BellSouth in writing of such condition and its effect upon the Site Schedule and
the Project Schedule. All costs and expenses incurred by Vendor arising out of
or by reason of the discovery of any such condition on the Site (including,
without limitation, costs and expenses paid or incurred to rectify such
condition) shall be borne by Vendor. The applicable Site Schedule, the Project
Schedule, the Scheduled Commencement Date and the Project Completion Date, each
only as they apply to the affected Site, shall be adjusted pursuant to Section
6.04(b) to reflect all additional time which will be required for the
performance of any of the duties or obligations of Vendor under this Agreement
as a result of any such condition, and the adjustment shall be deemed an
Excusable Delay.

      8.04 Geotechnical Subsurface and Soil Investigation. (a) Vendor shall
obtain, perform and analyze all reasonably appropriate geotechnical data, soil
and subsurface tests and other soil engineering tests and reports necessary to
the design, engineering, permitting, and construction of the Tower and the
Improvements (except that the provisions of this Section 8.04 shall not apply to
the Environmental Assessment).

           (b) If Vendor shall have timely obtained all reasonably appropriate
tests, but, nonetheless, concealed and unknown conditions that affect the
performance of the Work are encountered below ground or in an existing structure
other than the Work, then (i) Vendor shall bear all costs and expenses arising
out of or by reason of the existence of any such condition on the Site and (ii)
the Scheduled Commencement Date, the Site Schedule, the Project Schedule and the
Project Completion Date, in each case as it applies to such Site, shall be
adjusted to reflect all additional time which will be required for the
performance of any of the duties or obligations of Vendor under this Agreement
as to such Site as a result of any such condition. Notwithstanding anything to
the contrary in this Agreement, Vendor's obligation to pay all losses and
expenses relative to an environmental conditions under Section 8.03(b) or a
concealed, unknown condition under Section 8.04(b) is limited to $10,000 per
Site in the aggregate. If such costs are more than $10,000 for a Site, Vendor
may elect to reject such Site and such Site shall no longer be part of the
Project or subject to this Agreement.

      8.05 Additional Environmental Requirements. Prior to commencement of
construction in respect of any Site (except as to any Potential Colocation Sites
or other colocation sites, prior to obtaining any Permit), and as a condition to
any Anchor Tenant's obligation to accept any Site, Proposed Colocation Site or
other colocation site or opportunity from Vendor, Vendor shall perform an
analysis to determine whether (i) the proposed site is in a historical district,
(ii) there is any endangered species that may be affected by the proposed site,

proposed site, including without limitation diesel fuel spills or similar
conditions or (iv) the potential site is located in a floodplain (as defined by
the FCC). Vendor shall deliver the results of each such analysis to BellSouth
upon completion of such analysis, together with a written certification based on
the consulting reports received by Vendor, to the results thereof, including
Vendor's certification that there is no condition of the type described in
clause (i), (ii), (iii) or (iv). All costs and expenses incurred by Vendor
arising out of or by reason of compliance with the requirements of this Section
8.05 shall be borne by Vendor.

rent such Premises from the Bankruptcy Remote Entity, all pursuant to and in
accordance with the terms and conditions set forth in the Master Lease and a
Site Lease for such Site, provided that no Rent is payable for any Site unless

Bankruptcy Remote Entity has a leasehold interest prior to the execution and
recordation of a Site Lease for such Site and (ii) submit to the appropriate
recording office each Site Lease not later than seven (7) days after the
execution thereof, and cause such memorandum or Site Lease, as the case may be,
to be so recorded in such recording office.

      9.04 Effect of Master Lease and Site Lease. The parties acknowledge and
agree that upon the Completion of a Site, in addition to any obligations of
Vendor hereunder that survive the Completion of such Site, the respective duties
and responsibilities of the parties pertaining to the lease of such Site shall

      10.02 Evidence of Insurance. Vendor shall furnish BellSouth with
appropriate certificates evidencing the insurance required to be maintained by
Vendor hereunder. If Vendor for any reason fails to obtain and/or maintain in
force any of the insurance required under Section 10.01, then Vendor shall, and
Vendor does hereby agree to, indemnify each BellSouth Indemnitee against, and
hold, save, and defend each BellSouth Indemnitee harmless from, any and all
claims, demands, actions, causes of action, suits, liabilities, damages, losses,
costs and expenses of any kind or nature whatsoever (including, without
limitation, reasonable attorneys' fees and court costs incurred in enforcing
this indemnity and otherwise) which such BellSouth Indemnitee may suffer or
incur, or which may be asserted against such BellSouth Indemnitee, whether
meritorious or not, against which such BellSouth Indemnitee would or should have
been insured under any required insurance which Vendor does not for any reason
obtain or maintain in force.

      10.03 Waiver of Subrogation. Each insurance policy maintained by Vendor
with respect to the Project shall contain a waiver of subrogation clause, so
that no insurer shall have any claim over or against BellSouth, by way of
subrogation or otherwise, with respect to any claims which are insured under any

                              LIABILITY; INDEMNITY

      11.01 Liquidated Damages. (a) Except as expressly provided in this
Agreement, if Vendor delays in performing any of its obligations pursuant to any
Site Schedule or the Project Schedule, then BellSouth will have the option,
exercisable in its sole discretion, to adjust any Site Schedule or the Project
Schedule so as to allow Vendor to perform the obligations which Vendor could not
perform due to Vendor's delay to a later time; provided that no such adjustment
shall be effective unless evidenced by a writing executed by BellSouth.

            (b) Except as provided in Section 14.02, if Vendor fails to meet its
obligation to Complete any Site or the Project or any phase or milestone thereof
in accordance with the applicable Site Schedule or the Project Schedule (subject
to any extensions thereof in respect of Excusable Delays pursuant to Section
6.04(b)), BellSouth will have the right to liquidated damages in respect of each
Site that has not been Completed in an amount equal to $5,000 per month for each
month that such failure continues (the "Liquidated Damages") (subject to
proration). If Vendor owes Liquidated Damages in respect of any Site, and such
Site is Completed by the date that is thirty (30) days after the Scheduled
Completion Date therefor, BellSouth shall receive credits in the aggregate
amount of such Liquidated Damages against the next succeeding monthly rent
payments owed under the applicable Site Lease. If such Site is not Completed by
such date, Liquidated Damages shall be payable by Vendor in cash, on demand,
made by BellSouth at any time after such date.

            (c) The payment of the Liquidated Damages shall not relieve Vendor
from its obligations to construct and install the Towers and Improvements, and
perform its other obligations hereunder in accordance with the respective Site
Schedules and the Project Schedule. The parties hereto acknowledge that the
amount of the Liquidated Damages payable by Vendor to BellSouth under this
Section 11.01 constitute liquidated damages and not penalties, that the injuries
to BellSouth caused by Vendor's delays described above are difficult or
impossible to estimate accurately, and that the sums payable herein are
reasonable estimates of the probable losses associated with such injuries. The
parties further acknowledge that BellSouth may not assert other damages separate
from and in addition to the Liquidated Damages and this shall be BellSouth's
sole remedy with respect to Vendor's failure to fulfill its obligation asserted
in Section 11.01(b).

      11.02 Indemnity of BellSouth. Vendor shall, and Vendor does hereby agree
to, indemnify and hold harmless each BellSouth Indemnitee from and against any
loss, damage, liability, cost, expense, action or claim, including reasonable
attorneys' fees and amounts paid in settlement ("Claims"), by reason of or
arising out of: (a) personal injury, death, and damage to tangible property
resulting from the intentional or negligent acts or omissions of Vendor's
directors, officers, employees, agents, consultants, contractors or
subcontractors in connection with the Completion of the Project and performance
of this Agreement; (b) Vendor's breach of its obligations under this Agreement,
including without limitation in respect of any Services; and (c) Vendor's breach
of any representation or warranty in this Agreement, including without
limitation its warranty pursuant to Section 6.10.

      11.03 Indemnity of Vendor. BellSouth shall, and BellSouth does hereby
agree to, indemnify and hold harmless each Vendor Indemnitee from and against
any Claim, by reason of or arising out of (a) a personal injury, death, and
damage to tangible property resulting from the intentional or negligent acts or
omissions of BellSouth's directors, officers, employees, agents, consultants,
contractors or subcontractors in connection with BellSouth's performance of this
Agreement, and (b) BellSouth's breach of its obligations under this Agreement.

      11.04 Consequential Damages. Notwithstanding anything to the contrary
contained herein, neither party shall be liable to the other party under this
Agreement for loss of profits, loss of business, or any special, exemplary,
consequential or incidental damages of any kind or nature or for any reason,
including, without limitation, the breach of this Agreement, or any termination
of this Agreement, whether such liability is asserted on the basis of contract,
tort (including negligence or a strict liability) or otherwise, even if the
party has been advised of the possibility of such damages.

      11.05 Relationship to Insurance. In no event shall the indemnification
provisions of Section 11.01 above diminish, affect, impede or impair, in any
manner whatsoever, the benefits to which any BellSouth Indemnitee may be
entitled under any insurance policy required by this Agreement or otherwise with
respect to the Project, or under the terms of any waiver of any subrogation
contained therein.

      11.06 No Third-Party Beneficiaries. None of the duties and obligations of

create any liability of Vendor to, or any rights in, any person or entity other
than the BellSouth Indemnitees and the Vendor Indemnitees.

                        SBA COMMUNICATIONS CORPORATION

                             AMENDED AND RESTATED
                            1996 STOCK OPTION PLAN


     1.   Purpose.  The purpose of the 1996 Stock Option Plan ("Plan") of SBA
          -------
Communications Corporation ("Company") is to provide a means through which the
Company and its Subsidiaries may attract able persons to enter and remain in the
employ or other service of the Company and its Subsidiaries, including as
directors, and to provide a means whereby those key persons upon whom the
responsibilities of the successful administration and management of the Company
rest, and whose present and potential contributions to the welfare of the
Company are of importance, can acquire and maintain stock ownership, thereby
strengthening their commitment to the welfare of the Company and promoting an
identity of interest between shareholders and these key persons.

          A further purpose of the Plan is to provide such key persons with
additional incentive and reward opportunities designed to enhance the profitable
growth of the Company. The Plan provides for granting Incentive Stock Options,
Non-Qualified Stock Options, Stock Appreciation Rights, Restricted Stock Awards,
Phantom Stock Unit Awards and Performance Share Units, or any combination of the
foregoing.

     2.   Definitions.  The following definitions shall be applicable throughout
          -----------
the Plan.

          (1) "Appreciation Date" shall mean the date designated by a Holder of
Stock Appreciation Rights for measurement of the appreciation in the value of
rights awarded to him, which date shall be the date notice of such designation
is received by the Committee, or its designee.

          (2) "Award" shall mean, individually or collectively, any Incentive
Stock Option, Non-Qualified Stock Option, Stock Appreciation Right, Restricted
Stock Award, Phantom Stock Unit Award or Performance Share Unit Award.

          (3) "Award Period" shall mean a period of time within which
performance is measured for the purpose of determining whether an award of
Performance Share Units has been earned.

          (4) "Board" shall mean the Board of Directors of the Company.

          (5) "Cause" shall mean the Company or a Subsidiary having cause to
terminate a Participant's employment under any existing employment agreement
between the Participant and the Company or a Subsidiary or, in the absence of
such an employment agreement, upon (i) the determination by the Committee that
the Participant has failed to perform his duties to the Company or a
<PAGE>

Subsidiary (other than as a result of his incapacity due to physical or mental
illness or injury), which failure amounts to an intentional and extended neglect
of his duties to such party, (ii) the Committee's determination that the
Participant has engaged or is about to engage in conduct materially injurious to
the Company or a Subsidiary, or (iii) the Participant having been convicted of a
felony.

          (6)  "Change in Control" shall, unless the Board otherwise directs by
resolution adopted prior thereto, be deemed to occur if (i) any "person" (as
that term is used in Sections 13 and 14(d)(2) of the Exchange Act) other than
Steven E. Bernstein is or becomes the beneficial owner (as that term is used in
Section 13(d) of the Exchange Act), directly or indirectly, of twenty-five
percent (25%) or more of the voting stock; or (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board cease for any reason to constitute at least a majority thereof, unless
the election or the nomination for election by the Company's shareholders of
each new director was approved by a vote of at least three-quarters of the
directors then still in office who were directors at the beginning of the
period.  Any merger, consolidation or corporate reorganization in which the
owners of the Company's capital stock entitled to vote in the election of
directors ("Voting Stock") prior to said combination own fifty percent (50%) or
more of the resulting entity's Voting Stock shall not, by itself, be considered
a Change in Control.

          (7)  "Code" shall mean the Internal Revenue Code of 1986, as amended.

amendments or successor provisions to such section and any regulations under

or such other committee as may be appointed by the Board, each member of which

in any substantial gainful activity, as determined by the Committee based upon
medical evidence acceptable to it.

          (13) "Eligible Employee" shall mean any person regularly employed by
the Company or a Subsidiary on a full-time salaried basis who satisfies all of
the requirements of Section 6 hereof.

amended.

          (15) "Fair Market Value" shall mean (i) the average of the high and

Stock on the Nasdaq National Market for the ten (10) trading days immediately
preceding the date of determination, if the Common Stock is not then traded on a
national securities exchange; or (iii) the closing bid price (or average of bid
prices) last quoted by an established quotation service for over-the-counter
securities for the ten (10) trading days immediately preceding the date of

option is granted under the Plan, "Fair Market Value" shall be deemed to be the
fair value of the Common Stock as determined by the Compensation Committee of

and offer prices of the Common Stock in private transactions negotiated at arm's

                    copy of irrevocable instructions to a stockbroker to deliver
                    promptly to the Company an amount of sale or loan proceeds
                    sufficient to pay the Option Price.

          (3)  Stock Option Agreement.  Each Option granted under the Plan shall
be evidenced by a "Stock Option Agreement" between the Company and the Holder of
the Option containing such provisions as may be determined by the Committee, but
shall be subject to the following terms and conditions.

               (1)  Each Option or portion thereof that is exercisable shall be
                    exercisable for the full amount or for any part thereof,
                    except as otherwise determined by the terms of the Stock
                    Option Agreement.

               (2)  Each share of Stock purchased through the exercise of an
                    Option shall be paid for in full at the time of the
                    exercise. Each Option shall cease to be exercisable, as to
                    any share of Stock, when the Holder purchases the share or
                    exercises a related SAR or when the Option lapses.

               (3)  Options shall not be transferable by the Holder except by
                    will or the laws of descent and distribution and shall be
                    exercisable during the Holder's lifetime only by him or her.

               (4)  Each Option shall become exercisable by the Holder in
                    accordance with the vesting schedule (if any) established by
                    the Committee for the Award.

               (5)  Each Stock Option Agreement may contain an agreement that,
                    upon demand by the Committee for such a representation, the
                    Holder shall deliver to the Committee at the time of any
                    exercise of an Option a written representation that the
                    shares to be acquired upon such exercise are to be acquired
                    for investment and not for resale or with a view to the
                    distribution thereof. Upon such demand, delivery of such
                    representation prior to the

                                       8
<PAGE>

                    delivery of any shares issued upon exercise of an Option
                    shall be a condition precedent to the right of the Holder or
                    such other person to purchase any shares. In the event
                    certificates for Stock are delivered under the Plan with
                    respect to which such investment representation has been
                    obtained, the Committee may cause a legend or legends to be
                    placed on such certificates to make appropriate reference to
                    such representation and to restrict transfer in the absence
                    of compliance with applicable federal or state securities
                    laws.

          (4)  Other Terms and Conditions.  An Option granted pursuant to the
Plan shall become exercisable and shall lapse in such manner and within such
period or periods ("Option Period"), not to exceed ten (10) years from its Date
of Grant (or such shorter time period as may be otherwise specified herein), as
set forth in the Stock Option Agreement to be entered into in connection with
the grant of such Option.

          (5)  Grants to 10% Holders of Company Voting Stock.  Notwithstanding
Section 7(a), if an Incentive Stock Option is granted to a Holder who owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or of the Company and its Subsidiaries, the period
specified in the Stock Option Agreement for which the Option thereunder is
granted and at the end of which such Option shall expire shall not exceed five
(5) years from the Date of Grant of such Option and the Option Price shall be at
least one hundred ten percent (110%) of the Fair Market Value (on the Date of
Grant) of the Stock subject to the Option.

          (6)  Limitation.  To the extent the aggregate Fair Market Value (as
determined as of the Date of Grant) of Stock for which Incentive Stock Options
are exercisable for the first time by any Participant during any calendar year
(under all plans of the Company and its Subsidiaries) exceeds One Hundred
Thousand Dollars ($100,000), such excess Incentive Stock Options shall be
treated as Non-Qualified Stock Options.

          (7)  Voluntary Surrender. The Committee may permit the voluntary
surrender of all or any portion of any Non-Qualified Stock Option and its
corresponding SAR, if any, granted under the Plan to be conditioned upon the
granting to the Holder of a new Option for the same or a different number of
shares as the Option surrendered or require such voluntary surrender as a
condition precedent to a grant of a new Option to such Participant. Such new
Option shall be exercisable at the Option Price, during the exercise period, and
in accordance with any other terms or conditions specified by the Committee at
the time the new Option is

                                       9
<PAGE>

granted, all determined in accordance with the provisions of the Plan without
regard to the Option Price, exercise period, or any other terms and conditions
of the Non-Qualified Stock Option surrendered.

          (8)  Order of Exercise.  Options granted under the Plan may be
exercised in any order, regardless of the Date of Grant or the existence of any
other outstanding Option.

          (9)  Notice of Disposition.  Participants shall give prompt notice to
the Company of any disposition of Stock acquired upon exercise of an Incentive
Stock Option if such disposition occurs within either two (2) years after the
Date of Grant of such Option and/or one (1) year after the receipt of such Stock
by the Holder.

          (10) Termination of Employment.  If the Participant's employment by
the Company or any of its subsidiaries is terminated for any reason other than
death, only that portion of the Option exercisable at the time of such
termination of employment may thereafter be exercised, and it may not be
exercised more than three months after such termination nor after the expiration
date of the option, whichever date is earlier, unless such termination is by
reason of the Participant's permanent and total disability, in which case such
period of three months shall be extended to one year. Except as otherwise set
forth in the Stock Option Agreement, in all other respects, the Option shall
terminate upon such termination of employment.

     8.   Stock Appreciation Rights.  Any Option granted under the Plan may
          -------------------------
include an SAR, either at the time of grant or by amendment except that in the
case of an Incentive Stock Option, such SAR shall be granted only at the time of
grant of the related Option.  The Committee may also award to Participants SARs
independent of any Option.  An SAR shall be subject to such terms and conditions
not inconsistent with the Plan as the Committee shall impose, including, but not
limited to, the following:

          (1)  Vesting. An SAR granted in connection with an Option shall become
exercisable, be transferable and shall lapse according to the same vesting
schedule, transferability and lapse rules that are established by the Committee
for the Option. An SAR granted independent of an Option shall become
exercisable, be transferable and shall lapse in accordance with a vesting
schedule, transferability and lapse rules established by the Committee.
Notwithstanding the above, an SAR shall not be exercisable by a person subject
to Section 16(b) of the Exchange Act for at least six (6) months following the
Date of Grant.

          (2)  Failure to Exercise.  If on the last day of the Option Period (or
in the case of an SAR independent of an Option, the SAR period established by
the Committee), the Fair Market Value of the Stock exceeds the Option Price, the
Holder has not exercised the Option or SAR, and neither the Option nor the SAR
has lapsed, such SAR shall be deemed to have been exercised by the Holder on

                                       10
<PAGE>

such last day and the Company shall make the appropriate payment therefor.

          (3)  Payment.  The amount of additional compensation which may be
received pursuant to the award of one SAR is the excess, if any, of the Fair
Market Value of one share of Stock on the Appreciation Date over the Option
Price, in the case of an SAR granted in connection with an Option, or the Fair
Market Value of one (1) share of Stock on the Date of Grant, in the case of an
SAR granted independent of an Option.  The Company shall pay such excess in
cash, in shares of Stock valued at Fair Market Value, or any combination
thereof, as determined by the Committee. Fractional shares shall be settled in
cash.

          (4)  Designation of Appreciation Date.  A Participant may designate an
Appreciation Date at such time or times as may be determined by the Committee at
the time of grant by filing an irrevocable written notice with the Committee or
its designee, specifying the number of SARs to which the Appreciation Date
relates, and the date on which such SARs were awarded. Such time or times
determined by the Committee may take into account any applicable "window
periods" required by Rule 16b-3 under the Exchange Act.

          (5) Expiration.  Except as otherwise provided in the case of SARs
granted in connection with Options, the SARs shall expire on a date designated
by the Committee which is not later than ten (10) years after the date on which
the SAR was awarded.

     9.   Performance Shares,
          ------------------

          (1)  Award Grants.  The Committee is authorized to establish
Performance Share programs to be effective over designated Award Periods of not
less than one (1) year nor more than five (5) years.  At the beginning of each
Award Period, the Committee will establish in writing Performance Goals based
upon financial or other objectives for the Company for such Award Period and a
schedule relating the accomplishment of the Performance Goals to the Awards to
be earned by Participants.  Performance Goals may include absolute or relative
growth in earnings per share or rate of return on shareholders' equity or other
measurement of corporate performance and may be determined on an individual
basis or by categories of Participants.  The Committee may adjust Performance
Goals or performance measurement standards as it deems equitable in recognition
of extraordinary or non-recurring events experienced during an Award Period by
the Company, a Subsidiary or by any other corporation whose performance is
relevant to the determination of whether Performance Goals have been attained.
The Committee shall determine the number of Performance Share Units to be
awarded, if any, to each Participant who is selected to receive an Award.  The
Committee may add new Participants to a Performance Share program after its
commencement by making pro rata grants.

                                       11
<PAGE>

          (2)  Determination of Award.  At the completion of a Performance Share
program, or at other times as specified by the Committee, the Committee shall
calculate the amount earned with respect to each Participant's award by
multiplying the Fair Market Value on the Valuation Date by the number of
Performance Share Units granted to the Participant and multiplying the amount so
determined by a performance factor representing the degree of attainment of the
Performance Goals.

          (3)  Partial Awards.  A Participant for less than a full Award Period,
whether by reason of commencement or termination of employment or otherwise,
shall receive such portion of an Award, if any, for that Award Period as the
Committee shall determine.

          (4)  Payment of Non-deferred Awards. The amount earned with respect to
an Award shall be fully payable in shares of Stock based on the Fair Market
Value on the Valuation Date; provided, however, that, at its discretion, the
Committee may vary such form of payment as to any Participant upon the specific
request of such Participant. Except as provided in subparagraph 9(e), payments
of Awards shall be made as soon as practicable after the completion of an Award
Period.

          (5)  Deferral of Payment.  A Participant may file a written election
with the Committee to defer the payment of any amount otherwise payable pursuant
to subparagraph 9(d) on account of an Award to a period commencing at such
future date as specified in the election.  Such election must be filed with the
Committee no later than the last day of the month which is two-thirds of the way
through the Award Period during which the Award is earned, unless the Committee
specifies an earlier filing date.

          (6)  Separate Accounts.  At the conclusion of each Award Period, the
Committee shall cause a separate account to be maintained in the name of each
Participant with respect to whom all or a portion of an Award of Performance
Share Units earned under the Plan has been deferred. All amounts credited to
such account shall be fully vested at all times.

          (7)  Election of Form of Investment.  Within sixty (60) days from the
end of each Award Period, and at such time or times, if any, as the Committee
may permit, a Participant may file a written election with the Committee of the
percentage of the deferred portion of any Award of Performance Share Units which
is to be expressed in the form of dollars and credited with interest, the
percentage of such Award which is to be expressed in the form of Phantom Stock
Units and the percentage of such Award which is to be deemed invested in any
other hypothetical investment equivalent from time to time made available under
the Plan by the Committee.  In the event a Participant fails to file an election
within the time prescribed, one hundred percent (100%) of the deferred portion

                                       12
<PAGE>

of such Participant's Award shall be expressed in the form of Phantom Stock
Units.

          (8)  Interest Portion. The amount of interest credited with respect to
the portion of an Award credited to the Participant's account which is deferred
and credited with interest (the "Interest Portion") shall be equal to the amount
such portion would have earned had it been credited with interest from the last
day of the Award Period with respect to which the Award was made until the
seventh (7th) business day preceding the date as of which payment is made,
compounded annually, at the Company's rate of return on shareholders' equity for
each fiscal year that payment is deferred, or at such other rate as the
Committee may from time to time determine. The Committee may, in its sole
discretion, credit interest on amounts payable prior to the date on which the
Company's rate of return on shareholders' equity becomes ascertainable at the
rate applicable to deferred amounts during the year immediately preceding the
year of payment.

          (9)  Phantom Stock Unit Portion.  With respect to the portion of an
Award credited to the Participant's account which is deferred and expressed in
the form of Phantom Stock Units (the "Phantom Stock Unit Portion"), the number
of Phantom Stock Units so credited shall be equal to the result of dividing (i)
the Phantom Stock Unit Portion by (ii) the Fair Market Value on the date the
Award Period ended.

          (10) Dividend Equivalents. Within thirty (30) days from the payment of
a dividend by the Company on its Stock, the Phantom Stock Unit Portion of each
Participant's account shall be credited with additional Phantom Stock Units the
number of which shall be determined by (i) multiplying the dividend per share
paid on the Company's Stock by the number of Phantom Stock Units credited to his
account at the time such dividend was declared, then (ii) dividing such amount
by the Fair Market Value on the payment date for such dividend.

          (11) Payment of Deferred Awards.  Payment with respect to amounts
credited to the account of a Participant shall be made in a series of annual
installments over a period of ten (10) years, or such other period as the
Committee may direct, or as the Committee may allow the Participant to elect, in
either case at the time of the original deferral election.  Except as otherwise
provided by the Committee, each installment shall be withdrawn proportionately
from the Interest Portion and from the Phantom Stock Unit Portion of a
Participant's account based on the percentage of the Participant's account which
he originally elected to be credited with interest and with Phantom Stock Units,
or, if a later election has been permitted by the Committee and is then in
effect, based on the percentage specified in such later election.  Payments
shall commence on the date specified by the Participant in his deferral
election, unless the Committee in its sole discretion determines that payment
shall be made over a shorter period or in more

                                       13
<PAGE>

frequent installments, or commence on an earlier date, or any or all of the
above. If a Participant dies prior to the date on which payment with respect to
all amounts credited to his account shall have been completed, payment with
respect to such amounts shall be made to the Participant's beneficiary in a
series of annual installments over a period of five (5) years, unless the
Committee in its sole discretion determines that payment shall be made over a
shorter period or in more frequent installments, or both. To the extent
practicable, each installment payable hereunder shall approximate that part of
the amount then credited to the Participant's or beneficiary's account which, if
multiplied by the number of installments remaining to be paid would be equal to
the entire amount then credited to the Participant's account.

          (12) Composition of Payment.  The Committee shall cause all payments
with respect to deferred Awards to be made in a manner such that not more than
one-half of the value of each installment shall consist of Stock.  To that end,
payment with respect to the Interest Portion and the Phantom Stock Unit Portion
of a Participant's account shall be paid in cash and Stock as the Committee
shall determine in its sole discretion.  The determination of any amount to be
paid in cash for Phantom Stock Units shall be made by multiplying (i) the Fair
Market Value of one share of Stock on the date as of which payment is made, by
(ii) the number of Phantom Stock Units for which payment is being made.  The
determination of the number of shares of Stock, if any, to be distributed with
respect to the Interest Portion of a Participant's account shall be made by
dividing (i) one-half of the value of such portion on the date as of which
payment is made, by (ii) the Fair Market Value of one (1) share of Stock on such
date.  Fractional shares shall be paid in cash.

          (13) Alternative Investment Equivalents.  If the Committee shall have
permitted Participants to elect to have deferred Awards of Performance Share
Units invested in one or more hypothetical investment equivalents other than
interest or Phantom Stock Units, such deferred Awards shall be credited with
hypothetical investment earnings at such rate, manner and time as the Committee
shall determine.  At the end of the deferral period, payment shall be made in
respect of such hypothetical investment equivalents in such manner and at such
time as the Committee shall determine.

          (14) Adjustment of Performance Goals.  The Committee may, during the
Award Period, make such adjustments to Performance Goals as it may deem
appropriate, to compensate for, or reflect, any significant changes that may
have occurred during such Award Period in (i) applicable accounting rules or
principles or changes in the Company's method of accounting or in that of any
other corporation whose performance is relevant to the determination of whether
an Award has been earned or (ii) tax laws or other laws or regulations that
alter or affect the computation of the measures of Performance Goals used for
the calculation of Awards.

     10.  Restricted Stock Awards and Phantom Stock Units.
          -----------------------------------------------

          (1)  Award of Restricted Stock and Phantom Stock Units.

               (1)  The Committee shall have the authority (1) to grant
                    Restricted Stock and Phantom Stock Unit Awards, (2) to issue
                    or transfer Restricted Stock to Participants, and (3) to
                    establish terms, conditions and restrictions applicable to
                    such Restricted Stock and Phantom Stock Units, including the
                    Restricted Period, which may differ with respect to each
                    grantee, the time or times at which Restricted Stock or
                    Phantom Stock Units shall be granted or become vested and
                    the number of shares or units to be covered by each grant.

               (2)  The Holder of a Restricted Stock Award shall execute and
                    deliver to the Secretary of the Company an agreement with
                    respect to Restricted Stock and escrow agreement
                    satisfactory to the Committee and the appropriate blank
                    stock powers with respect to the Restricted Stock covered by
                    such agreements and shall pay to the Company, as the
                    purchase price of the shares of Stock subject to such Award,
                    the aggregate par value of such shares of Stock within sixty
                    (60) days following the making of such Award. If a
                    Participant shall fail to execute the agreement, escrow
                    agreement and stock powers or shall fail to pay such
                    purchase price within such period, the Award shall be null
                    and void. Subject to the restrictions set forth in Section
                    10(b), the Holder shall generally have the rights and
                    privileges of a shareholder as to such Restricted Stock,
                    including the right to vote such Restricted Stock. At the
                    discretion of the Committee, cash and stock dividends with
                    respect to the Restricted Stock may be either currently paid
                    or withheld by the Company for the Holder's account, and
                    interest may be paid on the amount of cash dividends
                    withheld at a rate and subject to such terms as determined
                    by the Committee. Cash or stock dividends so withheld by the
                    Committee shall not be subject to forfeiture.

               (3)  In the case of a Restricted Stock Award, the Committee shall
                    then cause stock certificates registered in the name of the
                    Holder to be

                                       15
<PAGE>

                    issued and deposited together with the stock powers with an
                    escrow agent to be designated by the Committee. The
                    Committee shall cause the escrow agent to issue to the
                    Holder a receipt evidencing any stock certificate held by it
                    registered in the name of the Holder.

               (4)  In the case of a Phantom Stock Units Award, no shares of
                    Stock shall be issued at the time the Award is made, and the
                    Company will not be required to set aside a fund for the
                    payment of any such Award. The Committee shall, in its sole
                    discretion, determine whether to credit to the account of,
                    or to currently pay to, each Holder of an Award of Phantom
                    Stock Units an amount equal to the cash dividends paid by
                    the Company upon one share of Stock for each Phantom Stock
                    Unit then credited to such Holder's account ("Dividend
                    Equivalents"). Dividend Equivalents credited to Holder's
                    account shall be subject to forfeiture and may bear interest
                    at a rate and subject to such terms as determined by the
                    Committee.

          (2)  Restrictions.

               (1)  Restricted Stock awarded to a Participant shall be subject
                    to the following restrictions until the expiration of the
                    Restricted Period: (1) the Holder shall not be entitled to
                    delivery of the stock certificate; (2) the shares shall be
                    subject to the restrictions on transferability set forth in
                    the grant; (3) the shares shall be subject to forfeiture to
                    the extent provided in subparagraph (d) and, to the extent
                    such shares are forfeited, the stock certificates shall be
                    returned to the Company, and all rights of the Holder to
                    such shares and as a shareholder shall terminate without
                    further obligation on the part of the Company.

               (2)  Phantom Stock Units awarded to any Participant shall be
                    subject to the following restrictions until the expiration
                    of the Restricted Period: (1) the units shall be subject to
                    forfeiture to the extent provided in subparagraph (d), and
                    to the extent such units are forfeited, all rights of the
                    Holder to such units shall terminate without further
                    obligation on the part of the Company and (2) any other

                                       16
<PAGE>

                    restrictions which the Committee may determine in advance
                    are necessary or appropriate.

               (3)  The Committee shall have the authority to remove any or all
                    of the restrictions on the Restricted Stock and Phantom
                    Stock Units whenever it may determine that, by reason of
                    changes in applicable laws or other changes in circumstances
                    arising after the date of the Restricted Stock Award or
                    Phantom Stock Award, such action is appropriate.

          (3)  Restricted Period.  The Restricted Period of Restricted Stock and
Phantom Stock Units shall commence on the Date of Grant and shall expire from
time to time as to that part of the Restricted Stock and Phantom Stock Units
indicated in a schedule established by the Committee with respect to the Award.

          (4)  Forfeiture Provisions.  In the event a Holder terminates
employment or service as a director during a Restricted Period, that portion of
the Award with respect to which restrictions have not expired ("Non-Vested
Portion") shall be treated as follows.

               (1)  Resignation or discharge:

                    --   The Non-Vested Portion of the Award shall be completely
                         forfeited.

               (2)  Normal Termination:

                    --   The Non-Vested Portion of the Award shall be prorated
                         for service during the Restricted Period and shall be
                         received as soon as practicable following termination.

               (3)  Death:

                    --   The Non-Vested Portion of the Award shall be prorated
                         for service during the Restricted Period and paid to
                         the Participant's beneficiary as soon as practicable
                         following death.

          (5)  Delivery of Restricted Stock and Settlement of Phantom Stock
Units.  Upon the expiration of the Restricted Period with respect to any shares
of Stock covered by a Restricted Stock Award, a stock certificate evidencing the
shares of Restricted Stock which have not then been forfeited and with respect
to which the Restricted Period has expired (to the nearest full share) shall be
delivered without charge to the Holder, or his beneficiary, free of all
restrictions under the Plan.

                                       17
<PAGE>

               Upon the expiration of the Restricted Period with respect to any
Phantom Stock Units covered by a Phantom Stock Unit Award, the Company shall
deliver to the Holder or his beneficiary without any charge one share of Stock
for each Phantom Stock Unit which has not then been forfeited and with respect
to which the Restricted Period has expired ("vested unit") and cash equal to any
Dividend Equivalents credited with respect to each such vested unit and the
interest thereon, if any; provided, however, that the Committee may, in its sole
discretion, elect to pay cash or part cash and part Stock in lieu of delivering
only Stock for vested units.  If cash payment is made in lieu of delivering
Stock, the amount of such payment shall be equal to the Fair Market Value for
the date on which the Restricted Period lapsed with respect to such vested unit.

          (6)  Payment for Restricted Stock.  Except as provided in subparagraph
10(a)(ii), a Holder shall not be required to make any payment for Stock received
pursuant to a Restricted Stock Award.

     11.  General.
          -------

          (1)  Additional Provisions of an Award. The award of any benefit under
the Plan may also be subject to such other provisions (whether or not applicable
to the benefit awarded to any other Participant) as the Committee determines
appropriate including, without limitation, provisions to assist the Participant
in financing the purchase of Common Stock through the exercise of Options,
provisions for the forfeiture of or restrictions on resale or other disposition
of shares acquired under any form of benefit, provisions giving the Company the
right to repurchase shares acquired under any form of benefit in the event the
Participant elects to dispose of such shares, and provisions to comply with
Federal and state securities laws and Federal and state income tax withholding
requirements.

          (2)  Privileges of Stock Ownership.  Except as otherwise specifically
provided in the Plan, no person shall be entitled to the privileges of stock
ownership in respect of shares of stock which are subject to Options or
Restricted Stock Awards, Performance Share Unit Awards or Phantom Stock Unit
Awards hereunder until such shares have been issued to that person upon exercise
of an Option according to its terms or upon sale or grant of those shares in
accordance with a Restricted Stock Award, Performance Share Unit Award or
Phantom Stock Unit Award.

          (3)  Government and Other Regulations.  The obligation of the Company
to make payment of Awards in Stock or otherwise shall be subject to all
applicable laws, rules, and regulations, and to such approvals by governmental
agencies as may be required.  The Company shall be under no obligation to
register under the Securities Act any of the shares of Stock issued under the
Plan.

                                       18
<PAGE>

If the shares issued under the Plan may in certain circumstances be exempt from
registration under the Securities Act, the Company may restrict the transfer of
such shares in such manner as it deems advisable to ensure the availability of
any such exemption.

          (4)  Tax Withholding. Notwithstanding any other provision of the Plan,
the Company or a Subsidiary, as appropriate, shall have the right to deduct from
all Awards, to the extent paid in cash, all federal, state or local taxes as
required by law to be withheld with respect to such Awards and, in the case of
Awards paid in Stock, the Holder or other person receiving such Stock may be
required to pay to the Company or a Subsidiary, as appropriate prior to delivery
of such Stock, the amount of any such taxes which the Company or Subsidiary is
required to withhold, if any, with respect to such Stock. Subject in particular
cases to the disapproval of the Committee, the Company may accept shares of
Stock of equivalent Fair Market Value in payment of such withholding tax
obligations if the Holder of the Award elects to make payment in such manner at
least six months prior to the date such tax obligation is determined.

          (5)  Claim to Awards and Employment Rights.  No employee or other
person shall have any claim or right to be granted an Award under the Plan nor,
having been selected for the grant of an Award, to be selected for a grant of
any other Award. Neither this Plan nor any action taken hereunder shall be
construed as giving any Participant any right to be retained in the employ of
the Company or a Subsidiary.

          (6)  Conditions. Each Participant to whom Awards are granted under the
Plan shall be required to enter into an Incentive Plan Agreement in a form
authorized by the Committee, which may include provisions that the Participant
shall not disclose any confidential information of the Company or any of its
Subsidiaries acquired during the course of such Participant's employment.

          (7)  Designation and Change of Beneficiary.  Each Participant shall
file with the Committee a written designation of one or more persons as the
beneficiary who shall be entitled to receive the amounts payable with respect to
an Award of Performance Share Units, Phantom Share Units or Restricted Stock, if
any, due under the Plan upon his death. A Participant may, from time to time,
revoke or change his beneficiary designation without the consent of any prior
beneficiary by filing a new designation with the Committee. The last such
designation received by the Committee shall be controlling; provided, however,
                                                            --------  -------
that no designation, or change or revocation thereof, shall be effective unless
received by the Committee prior to the Participant's death, and in no event
shall it be effective as of a date prior to such receipt.

          (8)  Payments to Persons Other than Participants.  If the Committee
shall find that any person to whom any amount is payable

                                       19
<PAGE>

under the Plan is unable to care for his affairs because of illness or accident,
or is a minor, or has died, then any payment due to such person or his estate
(unless a prior claim therefor has been made by a duly appointed legal
representative), may, if the Committee so directs the Company, be paid to his
spouse, child, relative, an institution maintaining or having custody of such
person, or any other person deemed by the Committee to be a proper recipient on
behalf of such person otherwise entitled to payment. Any such payment shall be a
complete discharge of the liability of the Committee and the Company therefor.

          (9)  No Liability of Committee Members. No member of the Committee
shall be personally liable by reason of any contract or other instrument
executed by such member or on his behalf in his capacity as a member of the
Committee nor for any mistake of judgment made in good faith, and the Company
shall indemnify and hold harmless each member of the Committee and each other
employee, officer or director of the Company to whom any duty or power relating
to the administration or interpretation of the Plan may be allocated or
delegated, against any cost or expense (including counsel fees) or liability
(including any sum paid in settlement of a claim) arising out of any act or
omission to act in connection with the Plan unless arising out of such person's
own fraud or bad faith; provided, however, that approval of the Board shall be
                        --------  -------
required for the payment of any amount in settlement of a claim against any such
person. The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under the
Company's Articles of Incorporation or By-Laws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold them
harmless.

          (10) Governing Law.  The Plan will be administered in accordance with
federal laws, or in the absence thereof, the laws of the State of Florida.

          (11) Funding. Except as provided under Section 10, no provision of the
Plan shall require the Company, for the purpose of satisfying any obligations
under the Plan, to purchase assets or place any assets in a trust or other
entity to which contributions are made or otherwise to segregate any assets, nor
shall the Company maintain separate bank accounts, books, records, or other
evidence of the existence of a segregated or separately maintained or
administered fund for such purposes. Holders shall have no rights under the Plan
other than as unsecured general creditors of the Company, except that insofar as
they may have become entitled to payment of additional compensation by
performance of services, they shall have the same rights as other employees
under general law.

          (12) Nontransferability. A person's rights and interest under the
Plan, including amounts payable, may not be sold, assigned, donated or
transferred or otherwise disposed of,

                                       20
<PAGE>

mortgaged, pledged or encumbered except, in the event of a Holder's death, to a
designated beneficiary to the extent permitted by the Plan, or in the absence of
such designation, by will or the laws of descent and distribution.

          (13) Reliance on Reports. Each member of the Committee and each member
of the Board shall be fully justified in relying, acting or failing to act, and
shall not be liable for having so relied, acted or failed to act in good faith,
upon any report made by the independent public accountant of the Company and its
Subsidiaries and upon any other information furnished in connection with the
Plan by any person or persons other than himself.

          (14) Relationship to Other Benefits.  No payment under the Plan shall
be taken into account in determining any benefits under any pension, retirement,
profit sharing, group insurance or other benefit plan of the Company or any
Subsidiary except as otherwise specifically provided.

          (15) Expenses. The expenses of administering the Plan shall be borne
by the Company and its Subsidiaries.

          (16) Pronouns.  Masculine pronouns and other words of masculine gender
shall refer to both men and women.

          (17) Titles and Headings.  The titles and headings of the sections in
the Plan are for convenience of reference only, and in the event of any
conflict, the text of the Plan, rather than such titles or headings shall
control.

     12.  Changes in Capital Structure.  Options, Stock Unit Awards, Performance
          ----------------------------
Share Unit Awards, and any agreements evidencing such Awards, and Performance
Goals, shall be subject to adjustment or substitution, as determined by the
Committee in its sole discretion, as to the number, price or kind of a share of
Stock or other consideration subject to such Awards or as otherwise determined
by the Committee to be equitable (i) in the event of changes in the outstanding
Stock or in the capital structure of the Company, or of any other corporation
whose performance is relevant to the attainment of Performance Goals hereunder,
by reason of stock dividends, stock splits, recapitalizations, reorganizations,
mergers, consolidations, combinations, exchanges or other relevant changes in
capitalization occurring after the Date of Grant of any such Award or (ii) in
the event of any change in applicable laws or any change in circumstances which
results in or would result in any substantial dilution or enlargement of the
rights granted to, or available for, Participants in the Plan, or which
otherwise warrants equitable adjustment because it interferes with the intended
operation of the Plan.  In addition, in the event of any such adjustments or
substitution, the aggregate number of shares of Stock available under the Plan
shall be appropriately adjusted by the Committee, whose determination shall be
conclusive.  Any

                                       21
<PAGE>

adjustment in Incentive Stock Options under this Section 13 shall be made only
to the extent not constituting a "modification" within the meaning of Section
424(h)(3) of the Code, and any adjustments under this Section 13 shall be made
in a manner which does not adversely affect the exemption provided pursuant to
Rule 16b-3 under the Exchange Act. The Company shall give each Participant
notice of an adjustment hereunder and, upon notice, such adjustment shall be
conclusive and binding for all purposes.

     13.  Effect of Change in Control.
          ---------------------------

          (1)  In the event of a Change in Control, notwithstanding any vesting
schedule provided for hereunder or by the Committee with respect to an Award of
Options, Director Awards, SARs, Phantom Stock Units or Restricted Stock, such
Option or SAR shall become immediately exercisable for such period of time
specified in the Optionee's Stock Option Agreement with respect to one hundred
percent (100%) of the shares subject to such Option or SAR, and the Restricted
Period shall expire immediately with respect to one hundred percent (100%) of
the Phantom Stock Units or shares of Restricted Stock subject to Restrictions.

          (2)  In the event of a Change in Control, all incomplete Award Periods
in effect on the date the Change in Control occurs shall end on the date of such
change, and the Committee shall, (i) determine the extent to which Performance
Goals with respect to each such Award Period have been met based upon such
audited or unaudited financial information then available as it deems relevant,
(ii) cause to be paid to each Participant partial or full Awards with respect to
Performance Goals for each such Award Period based upon the Committee's
determination of the degree of attainment of Performance Goals, and (iii) cause
all previously deferred Awards to be settled in full as soon as possible.

          (3)  The obligations of the Company under the Plan shall be binding
upon any successor corporation or organization resulting from the merger,
consolidation or other reorganization of the Company, or upon any successor
corporation or organization succeeding to substantially all of the assets and
business of the Company.  The Company agrees that it will make appropriate
provisions for the preservation of Participant's rights under the Plan in any
agreement or plan which it may enter into or adopt to effect any such merger,
consolidation, reorganization or transfer of assets.

     14.  Nonexclusivity of the Plan.  Neither the adoption of this Plan by the
          --------------------------
Board nor the submission of this Plan to the shareholders of the Company for
approval shall be construed as creating any limitations on the power of the
Board to adopt such other incentive arrangements as it may deem desirable,
including, without limitation, the granting of stock options otherwise than
under this Plan, and such arrangements may be either applicable generally or
only in specific cases.

                                       22
<PAGE>

     15.  Amendments and Termination.  The Board may at any time terminate the
          --------------------------
Plan.  With the express written consent of an individual Participant, the Board
may cancel or reduce or otherwise alter the outstanding Awards thereunder if, in
its judgment, the tax, accounting, or other effects of the Plan or potential
payouts thereunder would not be in the best interest of the Company.  The Board
may, at any time, or from time to time, amend or suspend and, if suspended,
reinstate, the Plan in whole or in part; provided, however, that the Board shall
not, without further shareholder approval:

          (1)  Increase the maximum number of shares of Stock which may be
issued on exercise of Options, SARs, or pursuant to Restricted Stock Awards,
Phantom Stock Unit Awards, or Performance Share Unit Awards, except as provided
in Section 12;

          (2)  Change the maximum Option Price;

          (3)  Extend the maximum Option Term;

          (4)  Extend the termination date of the Plan; or

          (5)  Change the class of persons eligible to receive Awards under the
Plan.

     issued upon exercise of such Options or rights or upon any such awards
     under the Plan shall not exceed two million five hundred thousand
     (2,500,000). The shares of Class A Common Stock issuable upon exercise of

                 (b) The maximum number of shares which may be subject to
     Awards, granted under the Plan to any individual in any calendar year shall

such Option or other right was not exercised prior to its expiration,
cancellation or exercise may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1. Furthermore, any shares subject to
Awards which are adjusted pursuant to Section 11.3 and become exercisable with
respect to shares of stock of another corporation shall be considered canceled
and may again be optioned, granted or awarded hereunder, subject to the
limitations of Section 2.1. Shares of Class A Common Stock which are delivered
by the Holder or withheld by the Company upon the exercise of any Award under
the Plan, in payment of the exercise price thereof or tax withholding thereon,
may again be optioned, granted or awarded hereunder, subject to the limitations
of Section 2.1. If any shares of Restricted Stock are surrendered by the Holder
or repurchased by the Company pursuant to Section 7.4 or 7.5 hereof, such shares
may again be optioned, granted or awarded hereunder, subject to the limitations
of Section 2.1. Notwithstanding the provisions of this Section 2.2, no shares of
Class A Common Stock may again be optioned, granted or awarded if such action
would cause an Incentive Stock Option to fail to qualify as an incentive stock
option under Section 422 of the Code.

applicable provisions of Section 162(m) of the Code. Award Agreements evidencing

     Committee may grant any Award to a Section 162(m) Participant, including

     attainment of performance goals which are related to one or more of the

     each fiscal year or other designated fiscal period or period of service,
     the Committee shall certify in writing whether the applicable performance
     targets have been achieved for such fiscal year or other designated fiscal
     period or period of service. In determining the amount earned by a Section
     162(m) Participant, the Committee shall have the right to reduce (but not
     to increase) the amount payable at a given level of performance to take
     into account additional factors that the Committee may deem relevant to the
     assessment of individual or corporate performance for the fiscal year or
     other designated fiscal period or period of service.

               (d) Furthermore, notwithstanding any other provision of the Plan
     or any Award which is granted to a Section 162(m) Participant and is
     intended to qualify as performance-based compensation as described in
     Section 162(m)(4)(C) of the Code shall be subject to any additional
     limitations set forth in Section 162(m) of the Code (including any
     amendment to Section 162(m) of the Code) or any regulations or rulings
     issued thereunder that are requirements for qualification as performance-
     based compensation as described in Section 162(m)(4)(C) of the Code, and
     the Plan shall be deemed amended to the extent necessary to conform to such
     requirements.

          3.3. Limitations Applicable to Section 16 Persons.  Notwithstanding
               --------------------------------------------
any other provision of the Plan, the Plan, and any Award granted or awarded to
any individual who is then subject to Section 16 of the Exchange Act, shall be
subject to any additional limitations set forth in any applicable exemptive rule
under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of
the Exchange Act) that are requirements for the application of such exemptive
rule. To the extent permitted by applicable law, the Plan and Awards granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to
such applicable exemptive rule.

          3.4. Consideration.  In consideration of the granting of an Award
               -------------
under the Plan, the Holder shall agree, in the Award Agreement, to remain in the

applicable) the Company or any Subsidiary for a period of at least one year (or
such shorter period as may be fixed in the Award Agreement or by action of the

the case of an Independent Director, until the next annual meeting of
stockholders of the Company).

          3.5. At-Will Employment.  Nothing in the Plan or in any Award
               ------------------

     portion of the Option;

               (b) Such representations and documents as the Administrator, in
     its sole discretion, deems necessary or advisable to effect compliance with

     interest under the Code) and payable upon such terms as may be prescribed
     by the Administrator; (vi) allow payment, in whole or in part, through the
     delivery of a notice that the Holder has placed a market sell order with a
     broker with respect to shares of Class A Common Stock then issuable upon
     exercise of the Option, and that the broker has been directed to pay a
     sufficient portion of the net proceeds of the sale to the Company in

                                    --------  -------
to Performance Awards granted to Section 162(m) Participants, the Administrator
in its sole and absolute discretion may provide that Performance Awards may be

                                  ARTICLE IX.

                           STOCK APPRECIATION RIGHTS

          9.1. Grant of Stock Appreciation Rights. A Stock Appreciation Right
               ----------------------------------
may be granted to any key Employee or Consultant selected by the Committee. A
Stock Appreciation Right may be granted (a) in connection and simultaneously
with the grant of an Option, (b) with respect to a previously granted Option, or
(c) independent of an Option. A Stock Appreciation Right shall be subject to
such terms and conditions not inconsistent with the Plan as the Committee shall
impose and shall be evidenced by an Award Agreement.

          9.2. Coupled Stock Appreciation Rights
               ---------------------------------

               (a)  A Coupled Stock Appreciation Right ("CSAR") shall be related
     to a particular Option and shall be exercisable only when and to the extent
     the related Option is exercisable.

               (b)  A CSAR may be granted to the Holder erfor no more than the
     number of shares subject to the simultaneously or previously granted Option
     to which it is coupled.

                                       20
<PAGE>

               (c)  A CSAR shall entitle the Holder (or other person entitled to
     exercise the Option pursuant to the Plan) to surrender to the Company
     unexercised a portion of the Option to which the CSAR relates (to the
     extent then exercisable pursuant to its terms) and to receive from the
     Company in exchange therefor an amount determined by multiplying the
     difference obtained by subtracting the Option exercise price from the Fair
     Market Value of a share of Class A Common Stock on the date of exercise of
     the CSAR by the number of shares of Class A Common Stock with respect to
     which the CSAR shall have been exercised, subject to any limitations the
     Committee may impose.

          9.3. Independent Stock Appreciation Rights
               -------------------------------------

               (a)  An Independent Stock Appreciation Right ("ISAR") shall be
     unrelated to any Option and shall have a term set by the Committee.  An
     ISAR shall be exercisable in such installments as the Committee may
     determine.  An ISAR shall cover such number of shares of Class A Common
     Stock as the Committee may determine. The exercise price per share of Class
     A Common Stock subject to each ISAR shall be set by the Committee.  An ISAR
     is exercisable only while the Holder is an Employee or Consultant; provided
     that the Committee may determine that the ISAR may be exercised subsequent
     to Termination of Employment or Termination of Consultancy without cause,
     or following a Change in Control of the Company, or because of the Holder's
     retirement, death or disability, or otherwise.

               (b)  An ISAR shall entitle the Holder (or other person entitled
     to exercise the ISAR pursuant to the Plan) to exercise all or a specified
     portion of the ISAR (to the extent then exercisable pursuant to its terms)
     and to receive from the Company an amount determined by multiplying the
     difference obtained by subtracting the exercise price per share of the ISAR
     from the Fair Market Value of a share of Class A Common Stock on the date
     of exercise of the ISAR by the number of shares of Class A Common Stock
     with respect to which the ISAR shall have been exercised, subject to any
     limitations the Committee may impose.

          9.4. Payment and Limitations on Exercise
               -----------------------------------

               (a)  Payment of the amounts determined under Section 9.2(c) and
     9.3(b) above shall be in cash, in Class A Common Stock (based on its Fair
     Market Value as of the date the Stock Appreciation Right is exercised) or a
     combination of both, as determined by the Committee.  To the extent such
     payment is effected in Class A Common Stock it shall be made subject to
     satisfaction of all provisions of Section 6.3 above pertaining to Options.

               (b)  Holders of Stock Appreciation Rights may be required to
     comply with any timing or other restrictions with respect to the settlement
     or exercise of a Stock Appreciation Right, including a window-period
     limitation, as may be imposed in the

                                       21
<PAGE>

     discretion of the Committee.

                                  ARTICLE X.

                                ADMINISTRATION

          10.1.  Compensation Committee.  Prior to the Company's initial
                 ----------------------
registration of Class A Common Stock under Section 12 of the Exchange Act, the
Compensation Committee shall consist of the entire Board. Following such
registration, The Compensation Committee (or another committee or a subcommittee
of the Board assuming the functions of the Committee under the Plan) shall
consist solely of two or more Independent Directors appointed by and holding
office at the pleasure of the Board, each of whom is both a "non-employee
director" as defined by Rule 16b-3 and an "outside director" for purposes of
Section 162(m) of the Code. Appointment of Committee members shall be effective
upon acceptance of appointment. Committee members may resign at any time by
delivering written notice to the Board. Vacancies in the Committee may be filled
by the Board.

          10.2.  Duties and Powers of Committee.  It shall be the duty of the
                 ------------------------------
Committee to conduct the general administration of the Plan in accordance with
its provisions. The Committee shall have the power to interpret the Plan and the
Award Agreements, and to adopt such rules for the administration,
interpretation, and application of the Plan as are consistent therewith, to
interpret, amend or revoke any such rules and to amend any Award Agreement
provided that the rights or obligations of the Holder of the Award that is the
subject of any such Award Agreement are not affected adversely. Any such grant
or award under the Plan need not be the same with respect to each Holder. Any
such interpretations and rules with respect to Incentive Stock Options shall be
consistent with the provisions of Section 422 of the Code. In its sole
discretion, the Board may at any time and from time to time exercise any and all
rights and duties of the Committee under the Plan except with respect to matters
which under Rule 16b-3 or Section 162(m) of the Code, or any regulations or
rules issued thereunder, are required to be determined in the sole discretion of
the Committee. Notwithstanding the foregoing, the full Board, acting by a
majority of its members in office, shall conduct the general administration of
the Plan with respect to Options and Dividend Equivalents granted to Independent
Directors.

          10.3.  Majority Rule; Unanimous Written Consent.  The Committee shall
                 ----------------------------------------
act by a majority of its members in attendance at a meeting at which a quorum is
present or by a memorandum or other written instrument signed by all members of
the Committee.

          10.4.  Compensation; Professional Assistance; Good Faith Actions.
                 ---------------------------------------------------------
Members of the Committee shall receive such compensation for their services as
members as may be determined by the Board. All expenses and liabilities which
members of the Committee incur in connection with the administration of the Plan
shall be borne by the Company. The Committee may, with the approval of the
Board, employ attorneys, consultants, accountants, appraisers, brokers, or other
persons. The Committee, the Company and the Company's officers and Directors
shall be entitled to rely upon the advice, opinions or valuations of any such
persons. All actions taken and all interpretations and determinations made by
the Committee or the Board in good faith shall be final and binding upon all
Holders, the Company and all other interested

                                       22
<PAGE>

persons. No members of the Committee or Board shall be personally liable for any
action, determination or interpretation made in good faith with respect to the
Plan or Awards, and all members of the Committee and the Board shall be fully
protected by the Company in respect of any such action, determination or
interpretation.

          10.5.  Delegation of Authority to Grant Awards.  The Committee may,
                 ---------------------------------------
but need not, delegate from time to time some or all of its authority to grant
Awards under the Plan to a committee consisting of one or more members of the
Committee or of one or more officers of the Company; provided, however, that the
Committee may not delegate its authority to grant Awards to individuals (i) who
are subject on the date of the grant to the reporting rules under Section 16(a)
of the Exchange Act, (ii) who are Section 162(m) Participants or (iii) who are
officers of the Company who are delegated authority by the Committee hereunder.
Any delegation hereunder shall be subject to the restrictions and limits that
the Committee specifies at the time of such delegation of authority and may be
rescinded at any time by the Committee. At all times, any committee appointed
under this Section 10.5 shall serve in such capacity at the pleasure of the
Committee.

                                  ARTICLE XI.

                           MISCELLANEOUS PROVISIONS

          11.1.  Not Transferable. No Award under the Plan may be sold, pledged,
                 ----------------
assigned or transferred in any manner other than by will or the laws of descent
and distribution or, subject to the consent of the Administrator, pursuant to a
DRO, unless and until such Award has been exercised, or the shares underlying
such Award have been issued, and all restrictions applicable to such shares have
lapsed. No Award or interest or right therein shall be liable for the debts,
contracts or engagements of the Holder or his successors in interest or shall be
subject to disposition by transfer, alienation, anticipation, pledge,
encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law by judgment, levy, attachment, garnishment
or any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect, except to
the extent that such disposition is permitted by the preceding sentence.

          Notwithstanding the foregoing provisions of this Section 11.1, the
Administrator, in its sole discretion, may determine to grant to any Holder a
Non-Qualified Stock Option which, by its terms as set forth in the applicable
Award Agreement, may be transferred by the Holder, in writing and with prior
written notice to the Administrator, by gift, without the receipt of any
consideration, to any child, stepchild, grandchild, parent, stepparent,
grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law,
father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law,
including adoptive relationships, any person sharing the Holder's household
(other than a tenant or employee), a trust in which such persons have more than
fifty percent of the beneficial interest, a foundation in which such persons (or
the Holder) control the management of assets, and any other entity in which such
persons (or the Holder) own more than fifty percent of the voting interests,
provided, that a Non-Qualified Stock Option that has been so transferred shall
- --------
continue to be subject to all of the terms and conditions of the Non-Qualified

                                       23
<PAGE>

Stock Option as applicable to the original Holder, and the transferee shall
execute any and all such documents requested by the Administrator in connection
with the transfer, including without limitation to evidence the transfer and to
satisfy any requirements for an exemption for the transfer under applicable
federal and state securities laws.

          11.2.  Amendment, Suspension or Termination of the Plan. Except as
                 ------------------------------------------------
otherwise provided in this Section 11.2, the Plan may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time
to time by the Administrator. However, without approval of the Company's
stockholders given within twelve months before or after the action by the
Administrator, no action of the Administrator may, except as provided in Section
11.3, increase the limits imposed in Section 2.1 on the maximum number of shares
which may be issued under the Plan. No amendment, suspension or termination of
the Plan shall, without the consent of the Holder alter or impair any rights or
obligations under any Award theretofore granted or awarded, unless the Award
itself otherwise expressly so provides. No Awards may be granted or awarded
during any period of suspension or after termination of the Plan, and in no
event may any Incentive Stock Option be granted under the Plan after the first
to occur of the following events:

                 (a)  The expiration of ten years from the date the Plan is
     adopted by the Board; or

                 (b)  The expiration of ten years from the date the Plan is
     approved by the Company's stockholders under Section 11.4.


          11.3.  Changes in Class A Common Stock or Assets of the Company,
                 ---------------------------------------------------------
Acquisition or Liquidation of the Company and Other Corporate Events
- --------------------------------------------------------------------

                 (a)  Subject to Section 11.3 (d), in the event that the
     Administrator determines that any dividend or other distribution (whether
     in the form of cash, Class A Common Stock, other securities, or other
     property), recapitalization, reclassification, stock split, reverse stock
     split, reorganization, merger, consolidation, split-up, spin-off,
     combination, repurchase, liquidation, dissolution, or sale, transfer,
     exchange or other disposition of all or substantially all of the assets of
     the Company, or exchange of Class A Common Stock or other securities of the
     Company, issuance of warrants or other rights to purchase Class A Common
     Stock or other securities of the Company, or other similar corporate
     transaction or event, in the Administrator's sole discretion, affects the
     Class A Common Stock such that an adjustment is determined by the
     Administrator to be appropriate in order to prevent dilution or enlargement
     of the benefits or potential benefits intended to be made available under
     the Plan or with respect to an Award, then the Administrator shall, in such
     manner as it may deem equitable, adjust any or all of

                      (i)  the number and kind of shares of Class A Common Stock
          (or other securities or property) with respect to which Awards may be
          granted or awarded (including, but not limited to, adjustments of the
          limitations in Section 2.1 on the maximum number and kind of shares

                                       24
<PAGE>

          which may be issued and adjustments of the Award Limit),

                    (ii)    the number and kind of shares of Class A Common
          Stock (or other securities or property) subject to outstanding Awards,
          and

                    (iii)  the grant or exercise price with respect to any
          Award.

               (b)  Subject to Section 11.3(d), in the event of any transaction
     or event described in Section 11.3(a) or any unusual or nonrecurring
     transactions or events affecting the Company, any affiliate of the Company,
     or the financial statements of the Company or any affiliate (including,
     without limitation, any Change in Control), or of changes in applicable
     laws, regulations, or accounting principles, the Administrator, in its sole
     and absolute discretion, and on such terms and conditions as it deems
     appropriate, either by the terms of the Award or by action taken prior to
     the occurrence of such transaction or event and either automatically or
     upon the Holder's request, is hereby authorized to take any one or more of
     the following actions whenever the Administrator determines that such
     action is appropriate in order to prevent dilution or enlargement of the
     benefits or potential benefits intended to be made available under the Plan
     or with respect to any Award under the Plan, to facilitate such
     transactions or events or to give effect to such changes in laws,
     regulations or principles:

                    (i)    To provide for either the purchase of any such Award
          for an amount of cash equal to the amount that could have been
          attained upon the exercise of such Award or realization of the
          Holder's rights had such Award been currently exercisable or payable
          or fully vested or the replacement of such Award with other rights or
          property selected by the Administrator in its sole discretion;

                    (ii)   To provide that the Award cannot vest, be exercised
          or become payable after such event;

                    (iii)  To provide that such Award shall be exercisable as to
          all shares covered thereby, notwithstanding anything to the contrary
          in Section 5.3 or 5.4 or the provisions of such Award;

                    (iv)   To provide that such Award be assumed by the
          successor or survivor corporation, or a parent or subsidiary thereof,
          or shall be substituted for by similar options, rights or awards
          covering the stock of the successor or survivor corporation, or a
          parent or subsidiary thereof, with appropriate adjustments as to the
          number and kind of shares and prices;

                    (v)    To make adjustments in the number and type of shares
          of Class A Common Stock (or other securities or property) subject to
          outstanding Awards, and in the number and kind of outstanding

                                       25
<PAGE>

          Restricted Stock or Deferred Stock and/or in the terms and conditions
          of (including the grant or exercise price), and the criteria included
          in, outstanding options, rights and awards and options, rights and
          awards which may be granted in the future; and

                    (vi)   To provide that, for a specified period of time prior
          to such event, the restrictions imposed under an Award Agreement upon
          some or all shares of Restricted Stock or Deferred Stock may be
          terminated, and, in the case of Restricted Stock, some or all shares
          of such Restricted Stock may cease to be subject to repurchase under
          Section 7.5 or forfeiture under Section 7.4 after such event.

               (c)  Subject to Sections 11.3(d), 3.2 and 3.3, the Administrator
     may, in its discretion, include such further provisions and limitations in
     any Award, agreement or certificate, as it may deem equitable and in the
     best interests of the Company.

               (d)  With respect to Awards which are granted to Section 162(m)
     Participants and are intended to qualify as performance-based compensation
     under Section 162(m)(4)(C), no adjustment or action described in this
     Section 11.3 or in any other provision of the Plan shall be authorized to
     the extent that such adjustment or action would cause such Award to fail to
     so qualify under Section 162(m)(4)(C), or any successor provisions thereto.
     No adjustment or action described in this Section 11.3 or in any other
     provision of the Plan shall be authorized to the extent that such
     adjustment or action would cause the Plan to violate Section 422(b)(1) of
     the Code.  Furthermore, no such adjustment or action shall be authorized to
     the extent such adjustment or action would result in short-swing profits
     liability under Section 16 or violate the exemptive conditions of Rule 16b-
     3 unless the Administrator determines that the Award is not to comply with
     such exemptive conditions.  The number of shares of Class A Common Stock
     subject to any Award shall always be rounded to the next whole number.

               (e)  Notwithstanding the foregoing, in the event that the Company
     becomes a party to a transaction that is intended to qualify for "pooling
     of interests" accounting treatment and, but for one or more of the
     provisions of this Plan or any Award Agreement would so qualify, then this
     Plan and any Award Agreement shall be interpreted so as to preserve such
     accounting treatment, and to the extent that any provision of the Plan or
     any Award Agreement would disqualify the transaction from pooling of
     interests accounting treatment (including, if applicable, an entire Award
     Agreement), then such provision shall be null and void.  All determinations
     to be made in connection with the preceding sentence shall be made by the
     independent accounting firm whose opinion  with respect to "pooling of
     interests" treatment is required as a condition to the Company's
     consummation of such transaction.

               (f)  The existence of the Plan, the Award Agreement and the
     Awards granted hereunder shall not affect or restrict in any way the right
     or power of the Company or the shareholders of the Company to make or
     authorize any adjustment,

                                       26
<PAGE>

     recapitalization, reorganization or other change in the Company's capital
     structure or its business, any merger or consolidation of the Company, any
     issue of stock or of options, warrants or rights to purchase stock or of
     bonds, debentures, preferred or prior preference stocks whose rights are
     superior to or affect the Class A Common Stock or the rights thereof or
     which are convertible into or exchangeable for Class A Common Stock, or the
     dissolution or liquidation of the company, or any sale or transfer of all
     or any part of its assets or business, or any other corporate act or
     proceeding, whether of a similar character or otherwise.

          11.4.  Approval of Plan by Stockholders.  The Plan will be submitted
                 --------------------------------
for the approval of the Company's stockholders within twelve months after the
date of the Board's initial adoption of the Plan. Awards may be granted or
awarded prior to such stockholder approval, provided that such Awards shall not
be exercisable nor shall such Awards vest prior to the time when the Plan is
approved by the stockholders, and provided further that if such approval has not
been obtained at the end of said twelve-month period, all Awards previously
granted or awarded under the Plan shall thereupon be canceled and become null
and void. In addition, if the Board determines that Awards other than Options or
Stock Appreciation Rights which may be granted to Section 162(m) Participants
should continue to be eligible to qualify as performance-based compensation
under Section 162(m)(4)(C) of the Code, the Performance Criteria must be
disclosed to and approved by the Company's stockholders no later than the first
stockholder meeting that occurs in the fifth year following the year in which
the Company's stockholders previously approved the Performance Criteria.

          11.5.  Tax Withholding.  The Company shall be entitled to require
                 ---------------
payment in cash or deduction from other compensation payable to each Holder of
any sums required by federal, state or local tax law to be withheld with respect
to the issuance, vesting, exercise or payment of any Award. The Administrator
may in its discretion and in satisfaction of the foregoing requirement allow
such Holder to elect to have the Company withhold shares of Class A Common Stock
otherwise issuable under such Award (or allow the return of shares of Class A
Common Stock) having a Fair Market Value equal to the sums required to be
withheld.

          11.6.  Loans. The Committee may, in its discretion, extend one or more
                 -----
loans to key Employees in connection with the exercise or receipt of an Award
granted or awarded under the Plan, or the issuance of Restricted Stock or
Deferred Stock awarded under the Plan. The terms and conditions of any such loan
shall be set by the Committee.

          11.7.  Forfeiture Provisions.  Pursuant to its general authority to
                 ---------------------
determine the terms and conditions applicable to Awards under the Plan, the
Administrator shall have the right to provide, in the terms of Awards made under
the Plan, or to require a Holder to agree by separate written instrument, that
(a) (i) any proceeds, gains or other economic benefit actually or constructively
received by the Holder upon any receipt or exercise of the Award, or upon the
receipt or resale of any Class A Common Stock underlying the Award, must be paid
to the Company, and (ii) the Award shall terminate and any unexercised portion
of the Award (whether or not vested) shall be forfeited, if (b)(i) a Termination
of Employment, Termination of Consultancy or Termination of Directorship occurs
prior to a specified date, or within a specified

                                       27
<PAGE>

time period following receipt or exercise of the Award, or (ii) the Holder at
any time, or during a specified time period, engages in any activity in
competition with the Company, or which is inimical, contrary or harmful to the
interests of the Company, as further defined by the Administrator or (iii) the
Holder incurs a Termination of Employment, Termination of Consultancy or
Termination of Directorship for cause.

          11.8.   Effect of Plan Upon Options and Compensation Plans.  The
                  --------------------------------------------------
adoption of the Plan shall not affect any other compensation or incentive plans
in effect for the Company or any Subsidiary. Nothing in the Plan shall be
construed to limit the right of the Company (a) to establish any other forms of
incentives or compensation for Employees, Directors or Consultants of the
Company or any Subsidiary or (b) to grant or assume options or other rights or
awards otherwise than under the Plan in connection with any proper corporate
purpose including but not by way of limitation, the grant or assumption of
options in connection with the acquisition by purchase, lease, merger,
consolidation or otherwise, of the business, stock or assets of any corporation,

3.2.   Election to Participate; Payroll Deductions

       An Eligible Employee may participate in the Plan only by means of payroll
deduction. An Eligible Employee may elect to participate in the Plan during an

<PAGE>

4.2.  Purchase of Shares
      ------------------

      (a) On each Exercise Date on which he or she is employed, each Participant
will automatically and without any action on his or her part be deemed to have
exercised his or her option to purchase at the Option Price the largest number
of whole shares of Class A Common Stock which can be purchased with the amount
in the Participant's Plan Account. The balance, if any, remaining in the
Participant's Plan Account (after exercise of his or her option) as of an
Exercise Date shall be carried forward to the next Option Period, unless the
Participant has elected to withdraw from the Plan pursuant to Section 6.1
hereof.

      (b) As soon as practicable following each Exercise Date, the Company will
deliver to the Participant a certificate issued in his or her name for such
number of shares purchased by such Participant pursuant to subsection (a) above.
In the event the Company is required to obtain from any commission or agency
authority to issue any such certificate, the Company will seek to obtain such
authority. Inability of the Company to obtain from any such commission or agency
authority which counsel for the Company deems necessary for the lawful issuance
of any such certificate shall relieve the Company from liability to any
Participant except to refund to him or her the amount withheld.

4.3.  Limitations on Purchase
      -----------------------

      No Employee shall be granted an option under the Plan which permits his or
her rights to purchase Class A Common Stock under the Plan or any other employee
stock purchase plan of the Company or any of its Subsidiaries to accrue at a
rate which exceeds $25,000 (as measured by the Fair Market Value of such Class A
Common Stock at the time the option is granted) for each calendar year such
option is outstanding. For purposes of this Section 4.3, the right to purchase
Class A Common Stock under an option accrues when the option (or any portion
thereof) becomes exercisable, and the right to purchase Class A Common Stock
which has accrued under one option under the Plan may not be carried over to any
other option.

4.4.  Transferability of Rights
      -------------------------

      An option granted under the Plan shall not be transferable and is
exercisable only by the Participant. No option or interest or right therein or
part thereof shall be liable for the debts, contracts or engagements of the
Participant or his or her successors in interest or shall be subject to
disposition by alienation, anticipation, pledge, encumbrance, assignment or any
other means whether such disposition be voluntary or involuntary or by operation
of law by judgment, levy, attachment, garnishment or any other legal or
equitable proceedings (including bankruptcy), and any attempt at disposition
thereof shall be null and void and of no effect.

5.1.  Class A Common Stock Reserved
      -----------------------------

      There shall be 500,000 authorized but unissued or reacquired shares of
Class A Common Stock reserved for issuance pursuant to this Plan, subject to
adjustment in accordance with Section 5.2 hereof.

5.2.  Adjustment for Changes in Class A Common Stock
      ----------------------------------------------

      In the event that adjustments are made in the number of outstanding shares
of Class A Common Stock or the shares are exchanged for a different class of
stock of the Company by reason of stock dividend, stock split or other
subdivision, the Committee shall make appropriate adjustments in (a) the number
and class of shares or other securities that may be reserved for purchase
hereunder and (b) the Option Price of outstanding options.

5.3.  Merger, Acquisition or Liquidation
      ----------------------------------

      In the event of the merger or consolidation of the Company into another
corporation, the acquisition by another corporation of all or substantially all
of the Company's assets or 80% or more of the Company's then outstanding voting
stock or the liquidation or dissolution of the Company, the date of exercise
with respect to outstanding options shall be the business day immediately
preceding the effective date of such merger, consolidation, acquisition,
liquidation or dissolution unless the Committee shall, in its sole discretion,
provide for the assumption or substitution of such options in a manner complying
with Section 424(a) of the Code.

5.4.  Insufficient Shares
      -------------------

      If the aggregate funds available for the purchase of Class A Common Stock
on any Exercise Date would cause an issuance of shares in excess of the number
provided for in Section 5.1 hereof, (a) the Committee shall proportionately
reduce the number of shares that would otherwise be purchased by each
Participant in order to eliminate such excess, and (b) the Plan shall
automatically terminate immediately after such Exercise Date.

5.5.  Rights as Stockholders
      ----------------------

      With respect to shares of Class A Common Stock subject to an option, a
Participant shall not be deemed to be a stockholder and shall not have any of
the rights or privileges of a stockholder. A Participant shall have the rights
and privileges of a stockholder when, but not until, a certificate for shares
has been issued to him or her following exercise of his or her option.

      (a) A Participant may cease payroll deductions during an Option Period by
delivering written notice of such cessation to the Company. Upon any such
cessation, such Participant may elect either to withdraw from the Plan pursuant
to subsection (b) below or to have amounts credited to his or her Plan Account
held in the Plan for the purchase of Class A Common Stock pursuant to Section
4.2. A Participant who ceases contributions to the Plan during any Option Period
shall not be permitted to resume contributions to the Plan during such Option
Period.

      (b) A Participant may withdraw from the Plan at any time by written notice
to the Company prior to the close of business on an Exercise Date. Within 21
days after the notice of withdrawal is delivered, the Company shall refund the
entire amount, if any, in a Participant's Plan Account to him or her, and
thereupon, the Participant's payroll deduction authorization, his or her
interest in the Plan and his or her option under the Plan shall terminate. Any
Eligible Employee who withdraws from the Plan may again become a Participant in
accordance with Section 3.2 hereof.

6.2.  Termination of Eligibility
      --------------------------

      (a) If a Participant ceases to be eligible under Section 3.1 hereof for
any reason, the amount in such Participant's Plan Account will be refunded to
the Participant or his or her designated beneficiary or estate within 21 days of
his or her termination of employment or other cessation of eligibility.

      (b) Upon payment by the Company to the Participant or his or her
beneficiary or estate of the remaining balance, if any, in Participant's Plan
Account, the Participant's interest in the Plan and the Participant's option
under the Plan shall terminate.

                                 ARTICLE VII.
                              GENERAL PROVISIONS

7.1.  Condition of Employment
      -----------------------

      Neither the creation of the Plan nor an Employee's participation therein
shall be deemed to create any right of continued employment or in any way affect
the right of the Company or a Subsidiary to terminate an Employee at any time
with or without cause.

7.2.  Amendment of the Plan
      ---------------------

      (a) The Board may amend, suspend or terminate the Plan at any time and
from time to time; provided, however, that without approval of the Company's

Plan may not be amended to increase the maximum number of shares subject to the
Plan or change the designation or class of Eligible Employees.

      (b) Upon termination of the Plan, the balance in each Participant's Plan
Account shall be refunded within 21 days of such termination.

trust or other restriction and may be used for any corporate purpose. No
interest will be paid to any Participant or credited under the Plan.

7.4.  Term; Approval by Stockholders
      ------------------------------

      The Plan shall terminate on the tenth anniversary of the date of its
initial approval by the stockholders of the Company, unless earlier terminated

of the Plan nor after termination of the Plan. The Plan will be submitted for
the approval of the Company's stockholders within 12 months after the date of
the Board's initial adoption of the Plan. Options may be granted prior to such
stockholder approval; provided, however, that such options shall not be
exercisable prior to the time when the Plan is approved by the stockholders;
provided further that if such approval has not been obtained by the end of said
12-month period, all options previously granted under the Plan shall thereupon
be canceled and become null and void.

7.5.  Effect Upon Other Plans
      -----------------------

      The adoption of the Plan shall not affect any other compensation or
incentive plans in effect for the Company or any Subsidiary. Nothing in this
Plan shall be construed to limit the right of the Company or any Subsidiary (a)
to establish any other forms of incentives or compensation for employees of the
Company or any Subsidiary or (b) to grant or assume options otherwise than under
this Plan in connection with any proper corporate purpose, including, but not by

acquisition, by purchase, lease, merger, consolidation or otherwise, of the
business, stock or assets of any corporation, firm or association.

7.6.  Conformity to Securities Laws

any amendment to Rule 16b-3 of the Exchange Act) that are

                                       7
<PAGE>

requirements for the application of such exemptive rule. To the extent permitted
by applicable law, the Plan shall be deemed amended to the extent necessary to
