                   SPECTRASITE HOLDINGS, INC. AND SUBSIDIARIES
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS


1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

         SpectraSite Holdings, Inc. ("SpectraSite") and its wholly owned
subsidiaries (collectively referred to as the "Company") are principally engaged
in providing services to companies operating in the telecommunications industry,
including leasing antenna sites on multi-tenant towers, network design, tower
construction and antenna installation throughout the United States and Canada.

PRINCIPLES OF CONSOLIDATION

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

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 amounts reported in the unaudited condensed
consolidated financial statements and accompanying notes. Actual results could
differ from those estimates.

REVENUE RECOGNITION

         Site leasing revenues are recognized when earned. Escalation clauses
present in the lease agreements with the Company's customers are recognized on a
straight-line basis over the term of the lease. Network service revenues from
site selection, construction and construction management activities are derived
under service contracts with customers which provide for billing on a time and
materials or fixed price basis. Revenues are recognized as services are
performed with respect to time and materials contracts. Revenues are recognized
using the percentage-of-completion method for fixed price contracts, measured by
the percentage of contract costs incurred to date compared to estimated total
contract costs. Costs and estimated earnings in excess of billings on
uncompleted contracts represent revenues recognized in excess of amounts billed.
Billings in excess of costs and estimated earnings on uncompleted contracts
represent billings in excess of revenues recognized. Provisions for estimated
losses on uncompleted contracts are made in the period in which such losses are
determined.

SIGNIFICANT CUSTOMERS

         In the three and six months ended June 30, 2000, one customer, which is
a significant shareholder of the Company, accounted for 27% and 26% of revenues,
respectively. In the three and six months ended June 30, 1999, the same customer
accounted for 40% and 34% of revenues, respectively.

RESTRUCTURING AND NON-RECURRING CHARGES

         In March 1999, the Company announced that it would relocate its
marketing and administrative operations from Little Rock, Arkansas and
Birmingham, Alabama to its corporate headquarters in Cary, North Carolina. As a
result, the Company recorded a non-recurring charge of $0.6 million for employee
termination and other costs related to the relocation of these activities.

INCOME TAXES

         The Company provides for income taxes at the end of each interim period
using the liability method based on the estimated effective tax rate for the
full fiscal year for each tax reporting entity. Cumulative adjustments to the
Company's estimate are recorded in the interim period in which a change in the
estimated annual effective rate is determined.

                   SPECTRASITE HOLDINGS, INC. AND SUBSIDIARIES
              NOTES TO THE UNAUDITED CONDENSED FINANCIAL STATEMENTS



EARNINGS PER SHARE

         Basic and diluted earnings per share are calculated in accordance with
Statement of Financial Accounting Standards No. 128 "Earnings per Share". The
Company had potential common stock equivalents related to its convertible
preferred stock until all such preferred stock converted into common stock in
February 2000 and also has potential common stock equivalents related to
outstanding stock options. These potential common stock equivalents were not
included in diluted earnings per share for all periods because the effect would
have been antidilutive. Accordingly, basic and diluted net loss per share are
the same for all periods presented.

RECLASSIFICATIONS

         Certain reclassifications have been made to the 1999 condensed
consolidated financial statements to conform to the 2000 presentation.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         In June 1998, the FASB issued Statement of Financial Accounting
Standards No. 133, Accounting for Derivative Instruments and Hedging Activities
("SFAS 133"). SFAS 133 requires that derivative instruments be recognized as
either assets or liabilities in the consolidated balance sheet based on their
fair values. Changes in the fair values of such derivative instruments will be
recorded either in results of operations or in other comprehensive income,
depending on the intended use of the derivative instrument. The initial
application of SFAS 133 will be reported as the effect of a change in accounting
principle. SFAS 133 is effective for all fiscal quarters beginning after June
15, 2000. The Company has not yet determined the effect that the adoption of
SFAS 133 will have on its consolidated financial statements.

UNAUDITED INTERIM FINANCIAL STATEMENTS

         The accompanying unaudited condensed consolidated financial statements

3. ACQUISITION ACTIVITIES

         On January 5, 2000, the Company acquired Vertical Properties, Inc. in a
merger for 225,000 shares of SpectraSite's common stock valued at $2.6 million
and repaid Vertical Properties' outstanding indebtedness of $1.5 million.
Vertical Properties was a broadcast tower development company formed to meet the
needs of broadcasters in secondary broadcast markets faced with the complexities
of converting to digital technology through site acquisition, tower placement
and leasing of antenna space.

         On January 5, 2000, the Company acquired Apex Site Management Holdings,
Inc. ("Apex") in a merger transaction for 4.5 million shares of SpectraSite's
common stock valued at $55.8 million and 191,465 options to purchase common
stock at an exercise price of $3.58 per share to the shareholders of Apex at the
closing of the merger. In addition, SpectraSite issued approximately 1.5 million
additional shares of common stock into escrow. These shares may be released to
Apex's shareholders on or about August 4, 2000 based on the average trading
price for SpectraSite's common stock for the 30-day

period immediately preceding such release. SpectraSite also used approximately
$6.2 million in cash to repay outstanding indebtedness and other obligations of
Apex in connection with the merger. Apex provides rooftop and in-building access
to wireless carriers.

         On January 28, 2000, the Company acquired substantially all of the
assets of International Towers Inc. and its subsidiaries, including S&W
Communications Inc. International Towers owned a broadcast tower manufacturing
facility and, through S&W Communications, provided integrated services for the
erection of broadcast towers, foundations and multi-tenant transmitter
buildings. The Company paid $5.4 million and issued 350,000 shares of
SpectraSite's common stock, valued at $7.1 million, in connection with this
acquisition.

         On March 14, 2000, the Company acquired substantially all of the assets
of TelCo Site Services, Inc. ("TelCo"), which provided network services.
SpectraSite issued 155,000 shares of common stock, valued at $4.2 million, in
connection with the acquisition. On May 2, 2000, the Company acquired
substantially all of the assets of BCS Wireless, Inc. ("BCS") for $2.0 million
in cash. BCS was a provider of network services.

         On May 18, 2000, the Company acquired Lodestar Towers, Inc.
("Lodestar") for approximately $178.6 million in cash. As of May 18, 2000,
Lodestar owned 110 wireless towers and 11 broadcast towers, and managed an
additional 120 wireless towers and 10 broadcast towers.

         The acquisitions of Vertical Properties, Apex, International Towers,
TelCo, BCS and Lodestar were accounted for as purchases, and the excess of cost
over fair value of the net assets acquired is being amortized on a straight-line
basis over 15 years. The operations of each are included in the consolidated
statement of operations from the date of acquisition.

         The following unaudited pro forma summary for the six months ended June
30, 2000 and 1999 presents the condensed consolidated results of operations as
if the 1999 acquisitions of Westower Corporation, Stainless, Inc. and the Doty
Moore companies and the 2000 acquisitions discussed above had occurred as of
January 1, 1999. 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 January 1, 1999 or of results that
may occur in the future.

         On June 8, 2000, the Company completed a joint venture, pursuant to
which the Company and Transco (the arm of BG Group plc which runs Britains' gas
network) will jointly develop a tower business to support Europe's growing
mobile communications industry. The Company and Transco each own 50% of the
joint venture. Transco transferred existing operational communications towers
and industrial land suitable for construction of new towers into the joint
venture, and the Company provided intellectual property and wireless network
development skills. The Company contributed $164.1 million in cash for future
developments and possible acquisitions. The Company also contributed Ample
Design to the joint venture and incurred other costs related to its investment
for a total investment in the joint venture of $190.0 million.

5. DEBT

12 7/8% SENIOR DISCOUNT NOTES DUE 2010

         In March 2000, SpectraSite issued $559.8 million aggregate principal
amount at maturity of senior discount notes due 2010 (the "2010 Notes") for
gross proceeds of $300.0 million. Interest on the 2010 Notes accretes daily at a
rate of 12.875% per annum, compounded semiannually, to an aggregate principal
amount of $559.8 million on March 15, 2005. Cash interest will not accrue on the
2010 Notes prior to March 15, 2005. Commencing March 15, 2005, cash interest
will accrue and be payable semiannually in arrears on each March 15 and
September 15, commencing September 15, 2005, at a rate of 12.875% per annum.
After March 15, 2005, the Company may redeem all or a portion of the 2010 Notes
at specified redemption prices, plus accrued and unpaid interest. On one or more
occasions prior to March 15, 2003, the Company may redeem up to 35% of the
aggregate principal amount at maturity of the 2010 Notes with the net cash
proceeds from one or more equity offerings. The redemption price would be
112.875% of the accreted value on the redemption date. The Company is required
to comply with certain covenants under the terms of the 2010 Notes that restrict
the Company's ability to incur additional indebtedness and make certain
payments, among other things.

10 3/4% SENIOR NOTES DUE 2010

         In March 2000, SpectraSite issued $200.0 million aggregate principal
amount of senior discount notes due 2010 (the "Cash Notes"). The Cash Notes bear
interest at a rate of 10.75% per annum, payable semi-annually in arrears on
March 15 and September 15, commencing September 15, 2000. After March 15, 2005,
the Company may redeem all or a portion of the Cash Notes at specified prices,
plus accrued interest. On one or more occasions prior to March 15, 2003, the
Company may redeem up to 35% of the Cash Notes with the net cash proceeds from
one or more equity offerings. The redemption price would be 110.75% of the
principal amount of the Cash Notes bought, plus accrued interest. The Company is
required to comply with certain covenants under the terms of the Cash Notes that
restrict the Company's ability to incur additional indebtness and make certain
payments, among other things.

6. SHAREHOLDERS' EQUITY

         On February 4, 2000, SpectraSite completed an underwritten public
offering of 25.6 million shares of common stock for net proceeds of
approximately $411.3 million. As a result of the offering, all outstanding
shares of Series, A, B and C preferred stock automatically converted to common
stock on a share-for-share basis.

7. BUSINESS SEGMENTS

         The Company operates in two business segments, site leasing and network
services. Prior period information has been restated to reflect the current
business segments. The site leasing segment provides for leasing and subleasing
of antenna sites on multi-tenant towers for a diverse range of wireless
communication services, including personal communication services, paging,
cellular and microwave. The network services segment offers a broad range of
network development services, including network design, tower construction and
antenna installation.

         In evaluating financial performance, management focuses on operating
profit (loss), excluding depreciation and amortization and restructuring
charges. This measure of operating profit (loss) is also before interest income,
interest expense, other income (expense) and income taxes. All reported segment
revenues are generated from external customers as intersegment revenues are not
significant.

         Summarized financial information concerning the reportable segments as
of and for the three months ended June 30, 2000 and 1999 is shown in the
following table. The "Other" column represents amounts excluded from specific
segments, such as income taxes, corporate general and administrative expenses,
depreciation and amortization, restructuring and other non-recurring charges and
interest. In addition, "Other" also includes corporate assets such as cash and
cash equivalents, tangible and intangible assets and income tax accounts which
have not been allocated to a specific segment.

8. SUBSEQUENT EVENTS

         On February 17, 2000, the Company signed a definitive agreement with
AirTouch Communications, Inc. to obtain the rights to approximately 430 towers
through a master sublease for approximately $155 million. The transaction is
expected to close in stages with the initial closing to occur no later than
November 15, 2000, if certain conditions are met.

         On July 17, 2000, the Company acquired 11 broadcast towers from Pegasus
Communications Corporation ("Pegasus") for 1,373,545 shares of unregistered
common stock. Under the agreement, the Company will also build up to five new
digital television towers for Pegasus in the next twelve months.

         On July 28, 2000, SpectraSite completed an underwritten public offering
of 11 million shares of common stock for net proceeds of approximately $220.2
million. On August 2, 2000, the underwriters purchased an additional 1,650,000
shares of common stock pursuant to the exercise of their overallotment option
for net proceeds of $33.2 million.

         On August 4, 2000, the Apex escrow agreement expired, and all of the
approximately 1.5 million shares of common stock held in escrow will be released
to SpectraSite for cancellation.

ITEM 2- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

GENERAL

         This report contains "forward looking statements" concerning our future
expectations, plans or strategies that involve risks and uncertainties. When we
use the words or phrases "will likely result," "expects" or "will continue," "is
anticipated," "estimated" or similar expressions (including oral confirmations
by our authorized executive officers), these statements are intended to identify
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Readers are cautioned not to place undue reliance
on any such forward-looking statements, each of which speaks only as of the date
made. Such statements are subject to certain risks and uncertainties that could
cause actual results to differ materially from historical earnings and those
presently anticipated or projected. Factors that could impact our expectations
include (i) substantial capital requirements and leverage principally as a
consequence of our ongoing acquisition and construction activities, (ii)
dependence on demand for wireless communications services, (iii) the success of
our network development and tower construction programs, and (iv) the successful
integration of assets and businesses we have acquired. We have no obligation to
release publicly the result of any revisions, which may be made to any
forward-looking statements to reflect anticipated or unanticipated events or
circumstances occurring after the date of such statements.

BUSINESS OVERVIEW

         SpectraSite's primary focus is on the ownership of multi-tenant towers
and leasing of antenna space on such towers. As of June 30, 2000, we had 3,474
towers in service, as compared to 2,765 towers at December 31, 1999.

         Historically, we have derived most of our revenues from network
services activities. As a result of recent acquisitions, principally the
acquisition of 2,000 communications towers from Nextel Communications, Inc. in
April 1999 and the merger with Westower Corporation in September 1999, we expect
that network services and antenna site leasing will generate most of our
revenues. We believe that our site leasing business will continue to represent a
substantial portion of our revenues and will continue to grow as we increase our
network of towers.

         Our two largest expense line items, other than interest expense and
cost of operations, have been depreciation and amortization and selling, general
and administrative expense. Depreciation expense primarily relates to our
communications towers, which we depreciate over 15 years. In 2000, amortization
expense is primarily due to goodwill associated with the acquisitions of
Westower, Stainless, the Doty Moore companies, Apex and International Towers. We
experienced a significant increase in selling, general and administrative
expense in 2000 as we integrated Westower's operations and increased our
employee base to market and manage our existing towers and to acquire and build
additional towers.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2000 COMPARED TO THE RESULTS FOR THE THREE MONTHS
ENDED JUNE 30, 1999.

         Consolidated revenues for the three months ended June 30, 2000 were
$77.8 million, an increase of $63.4 million from the three months ended June 30,
1999. Revenues from site leasing increased to $25.7 million for the three months
ended June 30, 2000 from $12.2 million for the three months ended June 30, 1999
primarily as a result of revenues derived from communications towers which we
acquired or constructed during 1999 and 2000. We owned 3,474 communications
towers at June 30, 2000 compared to 2,134 communications towers at June 30, 1999
and 106 at January 1, 1999.

         Revenues from network services increased to $52.1 million for the three
months ended June 30, 2000, as compared to $1.9 million in the three months
ended June 30, 1999, primarily as a result of the acquisitions of Westower,
Stainless, Doty-Moore and International Towers.

         Costs of operations increased to $51.5 million for the three months
ended June 30, 2000 from $5.0 million for the three months ended June 30, 1999.
The increase in costs was primarily attributable to operating costs of
communications towers acquired or constructed during 1999 and 2000 and to the
acquisitions of Westower, Stainless, Doty-Moore and International Towers.


                                       13
<PAGE>   14

         Selling, general and administrative expenses increased to $14.5 million
for the three months ended June 30, 2000 from $6.6 million for the three months
ended June 30, 1999. The increase is a result of expenses related to additional
corporate overhead and field operations to manage and operate the growth in the
ongoing activities of SpectraSite and the acquisitions of Westower, Stainless,
Doty-Moore, International Towers and Apex.

         Depreciation and amortization expense increased to $22.7 million for
the three months ended June 30, 2000 from $8.6 million for the three months
ended June 30, 1999 primarily as a result of the increased depreciation from the
towers we have acquired or constructed and amortization of goodwill related to
acquisitions.

         For the three months ended June 30, 2000, we recorded non-cash
compensation charges of $0.4 million related to the issuance of stock options
and restricted shares issued to employees. We recorded non-cash compensation
charges of $0.2 million in the quarter ended June 30, 1999 related to restricted
shares of common stock issued to an employee.

         As a result of the factors discussed above, our loss from operations
was $11.4 million for the three months ended June 30, 2000 compared to $6.0
million for the three months ended June 30, 1999.

         Net interest expense increased to $26.2 million during the three months
ended June 30, 2000 from $21.5 million for the three months ended June 30, 1999,
reflecting additional interest expense due to the issuance of SpectraSite's 12%
senior discount notes due 2008 in June 1998, its 11 1/4% senior discount notes
due 2009 in April 1999, its 12 7/8% senior discount notes due 2010 in March 2000
and its 10 3/4% senior notes due 2010 in March 2000, as well as borrowings under
our credit facility.

SIX MONTHS ENDED JUNE 30, 2000 COMPARED TO THE RESULTS FOR THE SIX MONTHS ENDED
JUNE 30, 1999.

         Consolidated revenues for the six months ended June 30, 2000 were
$153.0 million, an increase of $135.7 million from the six months ended June 30,
1999. Revenues from site leasing increased to $45.9 million for the six months
ended June 30, 2000 from $13.0 million for the six months ended June 30, 1999
primarily as a result of revenues derived from communications towers which we
acquired or constructed during 1999 and 2000. We owned 3,474 communications
towers at June 30, 2000 compared to 2,134 communications towers at June 30, 1999
and 106 at January 1, 1999.

         Revenues from network services increased to $107.1 million for the six
months ended June 30, 2000, as compared to $4.3 million in the six months ended
June 30, 1999, primarily as a result of the acquisitions of Westower, Stainless,
Doty-Moore and International Towers.

         Costs of operations increased to $101.8 million for the six months
ended June 30, 2000 from $5.9 million for the six months ended June 30, 1999.
The increase in costs was primarily attributable to operating costs of the
communications towers acquired or constructed during 1999 and 2000 and to the
acquisitions of Westower, Stainless, Doty-Moore and International Towers.

         Selling, general and administrative expenses increased to $30.2 million
for the six months ended June 30, 2000 from $9.4 million for the six months
ended June 30, 1999. The increase is a result of expenses related to additional
corporate overhead and field operations to manage and operate the growth in the
ongoing activities of SpectraSite and the acquisitions of Westower, Stainless,
Doty-Moore, International Towers and Apex.

         Depreciation and amortization expense increased to $42.7 million for
the six months ended June 30, 2000 from $9.1 million for the six months ended
June 30, 1999 primarily as a result of the increased depreciation from the
towers we have acquired or constructed and amortization of goodwill related to
acquisitions.

         For the six months ended June 30, 2000, we recorded non-cash
compensation charges of $0.7 million related to the issuance of stock options
and restricted shares issued to employees. We recorded non-cash compensation
charges of $0.2 million in the quarter ended June 30, 1999 related to restricted
shares of common stock issued to an employee.

         In March 1999, we announced that we would relocate our marketing and
administrative operations from Little Rock, Arkansas and Birmingham, Alabama to
our corporate headquarters in Cary, North Carolina. As a result, we recorded a
non-recurring charge of $0.6 million for employee termination and other costs
related to the relocation of these activities.




                                       14
<PAGE>   15


         As a result of the factors discussed above, our loss from operations
was $22.3 million for the six months ended June 30, 2000 compared to $7.9
million for the six months ended June 30, 1999.

         Net interest expense increased to $47.0 million during the six months
ended June 30, 2000 from $24.1 million for the six months ended June 30, 1999,
reflecting additional interest expense due to the issuance of SpectraSite's 12%
senior discount notes due 2008 in June 1998, its 11 1/4% senior discount notes
due 2009 in April 1999, its 12 7/8% senior discount notes due 2010 in March 2000
and its 10 3/4% senior notes due 2010 in March 2000, as well as borrowings under
our credit facility.

LIQUIDITY AND CAPITAL RESOURCES

         SpectraSite Holdings is a holding company whose only significant assets
are the outstanding capital stock of its subsidiaries, SpectraSite
Communications and SpectraSite International. Our only source of cash to pay
interest on and principal of our debt is distributions from SpectraSite
Communications. Prior to July 15, 2003, interest expense on the 2008 notes will
consist solely of non-cash accretion of an original issue discount and the notes
will not require annual cash interest payments. After such time, the 2008 notes
will have accreted to approximately $225.2 million and will require semi-annual
cash interest payments of $13.5 million. In addition, the notes mature on July
15, 2008. Similarly, the 2009 notes will not require cash interest payments
prior to October 15, 2004 and mature on April 15, 2009. On April 15, 2004, the
2009 notes will have accreted to $586.8 million and will require semi-annual
cash interest payments of $33.0 million. The 2010 discount notes will not
require cash interest payments prior to October 15, 2005, and mature March 15,
2010. On March 15, 2005, the 2010 discount notes will have accreted to $559.8
million and will require semi-annual cash interest payments of $36.0 million.
The 2010 cash notes require semi-annual cash interest payments of $10.75 million
and mature March 15, 2010. Furthermore, our credit facility provides for
periodic principal and interest payments.

         We currently have $200.0 million outstanding and $300.0 million
available under our credit facility to fund new tower construction or
acquisition activity. The weighted average interest rate on outstanding
borrowings under our credit facility as of June 30, 2000 was 10.1%. The facility
also requires compliance with certain financial covenants. At June 30, 2000, we
were in compliance with these covenants. In addition, our cash and cash
equivalents were $330.2 million at June 30, 2000.

         For the six months ended June 30, 2000, cash flows used in operating
activities were $14.9 million as compared to cash flows provided by operations
of $9.5 million for the six months ended June 30, 1999. The change is primarily
attributable to increases in working capital to support the growing operations
of the business partially offset by the favorable cash flow generated from
earnings before interest, depreciation and amortization.

         For the six months ended June 30, 2000, cash flows used in investing
activities were $597.4 million compared to $559.0 million for the six months
ended June 30, 1999. In the six months ended June 30, 2000, SpectraSite invested
$200.7 million in purchases of property and equipment and deposits on future
acquisitions, primarily related to the acquisition of communications towers. In
addition, we used an aggregate of $197.2 million in connection with our
acquisitions of Lodestar, Telco, Apex and Vertical Properties and the
acquisition of substantially all of the assets of International Towers and BCS
Wireless. We also invested $197.5 million in affiliates, primarily related to
our joint venture with Transco. In the six months ended June 30, 1999, we
invested $574.3 million in purchases of property and equipment and deposits on
future acquisitions, primarily related to the acquisition of wireless towers
from Nextel.

         In the six months ended June 30, 2000, cash flows provided by financing
activities were $904.7 million as compared to $687.4 million in the six months
ended June 30, 1999. The cash provided by financing activities in 2000 was
attributable to the proceeds from the issuance of common stock, the 2010
discount notes and the 2010 cash notes. The cash provided by financing
activities in 1999 was primarily attributable to the proceeds from the issuance
of preferred stock, the 2009 discount notes and from borrowing under the credit
facility.

         Our ability to fund capital expenditures, make scheduled payments of
principal of, or to pay interest on, our debt obligations, and our ability to
refinance any such debt obligations, including the 2008 notes, 2009 notes and
2010 notes 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, primarily to fund the construction and acquisition of additional
towers. We believe that cash flow from operations, available cash and
anticipated available borrowings under our credit facility will be




                                       15
<PAGE>   16


sufficient to fund capital expenditures and future acquisitions for the
foreseeable future. However, if acquisitions or other opportunities present
themselves more rapidly than we currently anticipate or if our estimates prove
inaccurate, we may seek additional sources of debt or equity or reduce the scope
of tower construction and acquisition activity. We cannot assure you that we
will generate sufficient cash flow from operations, or that future borrowings or
equity financing will be available, on terms acceptable to us, in amounts
sufficient to service our indebtedness and make anticipated capital
expenditures.

RECENT DEVELOPMENTS

         On February 17, 2000, we signed a definitive agreement with AirTouch
Communications, Inc. to obtain the rights to approximately 430 towers through a
master sublease for approximately $155 million. This transaction is expected to
close in stages with the initial closing to occur no later than November 15,
2000, if certain conditions are met.

         On July 28, 2000, SpectraSite completed an underwritten public offering
of 11 million shares of common stock for net proceeds of approximately $220.2
million. On August 2, 2000, the underwriters purchased an additional 1,650,000
shares of common stock pursuant to the exercise of their overallotment option
for net proceeds of $33.2 million.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In June 1998, the FASB issued Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities". SFAS 133 requires that derivative instruments be recognized as
either assets or liabilities in the consolidated balance sheet based on their
fair values. Changes in the fair values of such derivative instruments will be
recorded either in results of operations or in other comprehensive income,
depending on the intended use of the derivative instrument. The initial
application of SFAS 133 will be reported as the effect of a change in accounting
principle. SFAS 133 is effective for all fiscal years beginning after June 15,
2000. We have not yet determined the effect that the adoption of SFAS 133 will
have on our consolidated financial statements.

ITEM 3- QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         We use financial instruments, including fixed and variable rate debt,
to finance our operations. The information below summarizes our market risks
associated with debt obligations outstanding as of June 30, 2000. The following
table presents principal cash flows and related weighted average interest rates
by fiscal year of maturity. Variable interest rate obligations under our credit
facility are not included in the table. We have no long-term variable interest
obligations other than borrowings under our credit facility.

ITEM 5. OTHER INFORMATION

         On May 24, 2000, we entered into an exclusive agreement with Ubiquitel
Holdings, Inc., an affiliate of Sprint PCS, to construct, own and operate their
wireless communication towers in their 38 current markets, which are located in
the western and mid-western United States.

         On July 12, 2000, we entered into a master site lease agreement with
Cell-Loc Inc. for a minimum of 2,000 antenna site lease commencements over a
two-year period.

         For the three-month period ended June 30, 2000, our owned towers
increased by 404, to 3,474 towers. Of the 404 towers added during the second
quarter, 256 were newly built and 148 were acquisitions of existing towers. With
respect to the 3,070 towers owned at March 31, 2000, we executed 360 new tenant
leases during the second quarter at an average initial monthly rental of $1,575,
which is an annualized rate of .47 new tenants per tower.

         On August 4, 2000, the Apex escrow agreement expired, and all of the
approximately 1.5 million shares of common stock held in escrow will be released
to SpectraSite for cancellation.
