                     WESTOWER CORPORATION AND SUBSIDIARIES

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--BASIS OF PRESENTATION

     Westower Corporation (the "Company") designs, builds and maintains wireless
communications transmitting and receiving facilities for providers of wireless
communications services. The Company also owns and leases communications towers.
The Company operates throughout the U.S. and Canada.

     The unaudited condensed consolidated financial statements and notes thereto
at June 30, 1999 and September 30, 1998 (audited), and for the three and nine
months ended June 30, 1999 and 1998, reflect the October 28, 1997 merger with
Western Telecom Construction Ltd., an Alberta corporation, the May 29, 1998
merger with MJA Communications Corp., a Florida corporation, and the August 31,
1998 merger with Standby Services, Inc., a Texas corporation. All companies
design, fabricate and construct wireless transmitting and receiving facilities
and shelters for communications providers. The Company issued 835,000 shares of
its common stock for all the common shares of Western Telecom Construction Ltd.,
397,000 shares of its common stock for all of the common shares of MJA
Communications Corp., and 544,000 shares of its common stock for all of the
common shares of Standby Services, Inc. All of these mergers were accounted for
as a pooling-of-interests.

     On October 27, 1998, the Company changed its fiscal year-end from February
28 to September 30. All prior information has been restated to conform with a
September 30 year end.

     The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial reporting and in accordance with the instructions for Form
10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of
the information and disclosures normally required by generally accepted
accounting principles for complete financial statements or those normally
reflected in the Company's Annual Report on Form 10-KSB. The financial
information included herein reflects all adjustments (consisting of normal
recurring adjustments) which are, in the opinion of management, necessary for a
fair presentation of results for interim periods. Results of interim periods are
not necessarily indicative of the results to be expected for a full year. These
unaudited condensed consolidated financial statements should be read in
conjunction with the consolidated financial statements for the seven-month
Transition Period ended September 30, 1998 and the notes thereto included in the
Company's Form 10-KSB.

     CONSOLIDATION--The consolidated financial statements include the accounts
of the Company and its wholly owned domestic and Canadian subsidiaries.
Investments in subsidiaries in which the Company exercises significant influence
but which it does not control are accounted for using the equity method.
Investment in a 60% owned affiliated company is accounted for on the equity
method of accounting. The Company's equity (loss) earnings from this investment
during the three and nine months ended June 30, 1999 was $(83,000) and $142,000,
respectively, which has been included in other income. All material intercompany
accounts and transactions have been eliminated in consolidation.

     FOREIGN CURRENCY TRANSLATION--All asset and liability accounts of Canadian
operations are translated into U.S. dollars at current exchange rates. Revenues
and expenses are translated using the average exchange rate during the period.
Foreign currency translation adjustments are reported as a component of
comprehensive income and stockholders' equity in the consolidated balance sheet.
Exchange gains and losses from foreign currency transactions are included in
income currently.

     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. Examples of estimates subject to
possible revision based upon the outcome of future events include costs and
estimated earnings on uncompleted contracts, depreciation of property and
equipment, accrued income tax liabilities, and purchase price allocations for
acquisitions. Actual results could differ from those estimates.

  NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

     RECLASSIFICATION--Certain prior year amounts have been reclassified to
conform to the current year presentation and did not impact previously reported
stockholders' equity or cash flow.

NOTE 2--INVENTORY

     Inventory is stated at the lower of cost and estimated net realizable value
using the first-in, first-out method. Inventory consists of materials purchased
for future construction not associated with specific jobs.

NOTE 3--PROPERTY AND EQUIPMENT

     Property and equipment consists of the following:

</TABLE>

     For the three and nine months ended June 30, 1999, all potential common
shares were excluded from the computation of diluted earnings (loss) per share
because inclusion would have had an anti-dilutive effect on earnings (loss) per
share. For the three months ended June 30, 1998, shares associated with
convertible debt were excluded from the computation of diluted earnings per
share because inclusion would have had an anti-dilutive effect on earnings per
share. All other potential common shares have been included in the diluted
earnings per share calculations for the three and nine months ended June 30,
1998.

NOTE 10--SEGMENT INFORMATION

     The Company's operations are comprised of a number of communication tower
construction entities that were recently acquired. While management assesses the
operating results of each of these entities separately, as these entities and
its existing operations exhibit similar financial performance and have similar
economic characteristics, they have been aggregated as one segment.

     The following table summarizes contract and other revenues and long-lived
assets related to the respective countries in which the Company operates.

Westower Corporation

     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, of stockholders' equity, and of cash flows
present fairly, in all material respects, the financial position of Westower
Corporation and its subsidiaries at September 30, 1998, and the results of their
operations and their cash flows for the seven months ended September 30, 1998 in
conformity with accounting principles generally accepted in the United States.
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 of these statements in accordance with
auditing standards generally accepted in the United States which 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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for the opinion expressed above. The financial statements of Westower
Corporation for the three years in the period ended February 28, 1998 were
audited by other independent accountants whose report dated April 14, 1998,
except for the third paragraph in Note 3, as to which the date is May 31, 1998

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders
Westower Corporation

     We have audited the accompanying consolidated balance sheets of Westower
Corporation and Subsidiaries as of February 28, 1997 and 1998, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three years in the period ended February 28, 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 did not audit the financial statements of MJA Communications
Corporation, which are included in the financial statements of Westower
Corporation as discussed in Note 3 to the financial statements, and which
statements reflect total assets constituting 56% and 16% of consolidated total
assets as of February 28, 1997 and 1998 and total revenues constituting 22%, 57%
and 33% of consolidated total revenues for each of the three years in the period
ended February 28, 1998, respectively. Those statements were audited by other
auditors, whose report has been furnished to us, and our opinion, insofar as it
relates to the amounts included for MJA Communications Corporation, is based
solely on the report of the other auditors.

     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 and the reports of other auditors provide a
reasonable basis for our opinion.

     In our opinion, based on our audits and the reports of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the consolidated financial position of Westower Corporation
and Subsidiaries as of February 28, 1997 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
February 28, 1998 in conformity with generally accepted accounting principles.

                     WESTOWER CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--ORGANIZATION

     Westower Corporation (the "Company") was incorporated in Washington state
in June 1997 for the purpose of acquiring Westower Holdings Ltd. and its
wholly-owned subsidiaries, Westower Communications Ltd. and Westower
Communications, Inc. In connection with an initial public offering on October
15, 1997, the Company raised approximately $7.5 million in net cash proceeds.
Proceeds have been used in part to acquire the assets and operations of other
businesses.

     The Company is successor to operations begun in 1990 by Westower
Communication Ltd. It designs, builds and maintains wireless communication
transmitting and receiving facilities for providers of wireless communication
services. The Company also owns and leases wireless communication towers to
wireless communication providers. Principal operations are located in the
Pacific Northwest, including the Canadian provinces of British Columbia and
Alberta, and the Southeastern and Southwestern United States. Other operations
extend throughout the Western United States and into Eastern Canada.

     On October 27, 1998, the Company changed its fiscal year-end from February
28 to September 30 resulting in a seven month reporting period from March 1,
1998 to September 30, 1998 (the "Transition Period").

NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a) Consolidation--The consolidated financial statements include the
accounts of Westower Corporation and its wholly owned domestic and Canadian
subsidiaries.

     Investments in subsidiaries in which the Company exercises significant
influence but which it does not control are accounted for using the equity
method. At September 30, 1998, the Company has an equity investment in a joint
venture which engages in operations in Brazil that are similar to those of the
Company, in which it has an economic ownership interest of 60 percent. Revenues
and associated expenses are transacted in Canadian dollars. As of September 30,
1998, the Company's investment totaled $217,000, which has been included in
other assets, and the Company's equity earnings from this investment during the
Transition Period totaled $46,000, which has been included in contract and other
revenues earned.

     All material intercompany accounts and transactions have been eliminated in
consolidation.

     (b) 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 consolidated
financial statements. Examples of estimates subject to possible revision based
upon the outcome of future events include costs and estimated earnings on
uncompleted contracts, depreciation of property and equipment, accrued income
tax liabilities, and purchase price allocations for acquisitions. Actual results
could differ from those estimates.

     (c) Contract and Other Revenue and Cost Recognition--Revenue from
fixed-price construction contracts is recognized using the
percentage-of-completion method based on cost incurred to total estimated cost.
Revenue from contracts based upon time and materials is recognized based upon
hours worked and materials consumed. Most of the Company's contracts are
short-term and are completed in two to three months. Contract costs include all
direct material and labor costs and those indirect costs related to contract
performance. Provisions for estimated losses on uncompleted contracts are made
in the period in which such losses are determined.

     Costs and estimated earnings in excess of billings on uncompleted contracts
represents revenues recognized in excess of amounts billed. Billings in excess
of costs and estimated earnings on uncompleted contracts represents billings in
excess of revenues earned.

     The Company owns wireless communication towers which it leases to third
parties. Revenues are recognized on a monthly basis over the term of the leasing
agreement. Revenues and cost of services of approximately $170,000 and $25,000,
respectively, have been included in contract and other revenues earned and cost
of revenues earned, respectively, in the Transition Period.

     (d) Cash and Cash Equivalents--Cash and cash equivalents consist of cash in
banks and money market investments on deposit with major Canadian and U.S.
financial institutions. Investments with maturities of three months or less when
purchased are considered cash equivalents.

     (e) Inventory--Inventory consists of construction parts and supplies and is
stated at the lower of cost or market. Cost is determined using the first-in,
first-out (FIFO) method.

     (f) Property and Equipment--Property and equipment is recorded at cost.
Depreciation is computed using the straight-line method over the estimated
useful lives of the assets. Estimated useful lives by major asset category are
as follows: buildings--10-25 years; furniture, fixtures and equipment--3 to 10
years; wireless communication towers--20 years; vehicles--5 years. Gains or
losses on the dispositions of assets are recorded at the time of disposition.
The costs of normal repairs and maintenance are charged to expense as incurred.

     (g) Capitalized Software--Purchased software is capitalized at cost and
amortized over its estimated useful life of 3 years.

     (h) Intangible Assets--Business acquisition costs are allocated to the
tangible and identifiable intangible assets that are acquired. Business
acquisition costs allocated to contracts to purchase wireless communication
towers are amortized over a 20 year period upon acquisition of the wireless
communication towers, and costs allocated to non-compete agreements are
amortized over the term of the agreements, which are generally 5 years. The
excess of the aggregate purchase price over the fair value of the net assets
acquired and identifiable intangible assets acquired is recorded as goodwill.
Goodwill is amortized over a 20 year period. The Company amortizes its
intangible assets using the straight line method.

     (i) Financing Costs--Direct costs associated with obtaining debt financing
are deferred and are amortized over the term of the debt using the effective
interest method. Direct costs of obtaining commitments for financing are
deferred and charged to expense over the term of the commitments. Direct costs
associated with obtaining equity financing are charged to additional paid-in
capital as the related funds are raised. Deferred financing costs totaled $2.4
million at September 30, 1998, which has been included in other assets.
Accumulated amortization of deferred financing costs totaled $113,000 at
September 30, 1998.

     (j) Valuation of Long-Lived Assets--The Company periodically reviews its
long-lived assets and certain identifiable intangible assets, including
goodwill, whenever events or changes in circumstance indicate that the carrying
amount of an asset may be impaired and not recoverable. Adjustments are made if
the sum of the expected future undiscounted operating cash flows is less than
the carrying value of the asset.

     (k) Income Taxes--The Company accounts for income taxes under the liability
method. Deferred taxes are recognized for temporary differences between the
basis of assets and liabilities for financial statement and income tax purposes
at the enacted tax rates. The significant differences relate primarily to the
timing and recognition of depreciation and amortization of long-lived assets,
profit on uncompleted contracts, amortization of financing costs and bad debt
expense. Deferred tax amounts represent the future tax consequences of those
differences, which will either be deductible or taxable when the assets and
liabilities are recovered or settled. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amounts expected to be realized.
The Company files a consolidated federal income tax return in the United States.
The Company files separate tax returns for each of its Canadian subsidiaries in
Canada. Additionally, certain of the Company's operations are subject to
Provincial income taxes in Canada and state income taxes in the United States.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     (l) Foreign Currency Translation--All asset and liability accounts of
Canadian operations are translated into U.S. dollars at current exchange rates.
Revenues and expenses are translated using the average exchange rate during the
period. Foreign currency translation adjustments are reported as a component of
comprehensive income and stockholders' equity in the consolidated balance sheet.
Gains and losses resulting from foreign currency transactions are included in
income currently.

     (m) Earnings Per Share and Change in Accounting Policy--During fiscal year
ended February 28, 1998, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 128, Earnings Per Share. The new standard supersedes
Accounting Principles Board (APB) No. 15, Earnings Per Share and establishes
standards for computing and presenting earnings per share. Prior years have been
restated to conform with the new requirements.

     Basic earnings per share amounts are computed based on the weighted average
number of shares outstanding during the period after giving retroactive effect
to stock dividends and stock splits. Diluted earnings per share amounts are
computed by determining the number of additional shares that are deemed
outstanding from stock options and warrants, using the treasury stock method,
and convertible debentures.

     (n) Segment Information--In the Transition Period, the Company adopted SFAS
No. 131, Disclosures about Segments of an Enterprise and Related Information.
SFAS No. 131 supersedes SFAS 14, Financial Reporting for Segments of a Business
Enterprise, replacing the "industry segment" approach with the "management"
approach. The management approach designates the internal organization that is
used by management for making operating decisions and assessing performance as
the source of the Company's reportable segments. SFAS No. 131 also requires
disclosures about products and services, geographic areas, and major customers.
The adoption of SFAS No. 131 did not significantly affect the disclosure of
segment information previously reported (see "Segment Information" note).

     (o) New Accounting Standards--In June 1997, the Financial Accounting
Standards Board issued SFAS No. 133, Accounting for Derivative Instruments and
Hedging Activities. Among other provisions, SFAS No. 133 requires that entities
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. Gains and losses
resulting from changes in the fair values of those derivatives would be
accounted for depending on the use of the derivative and whether it qualifies
for hedge accounting. This Statement becomes effective beginning June 15, 2000,
for the Company. The Company is currently assessing the impact, if any, to its
financial position or results of operations.

     (p) Interim Financial Data (Unaudited)--As discussed in Note 1, on October
27, 1998 the Company changed its fiscal year end to September 30 from February
28. The information presented for the seven months ended September 30, 1997 is
unaudited. The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with Rule 10-01 of Regulation S-X. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments necessary for a fair presentation of results of the
interim period have been made and such adjustments were of a normal and
recurring nature. The results of operations and cash flows for the seven months
ended September 30, 1997 are not necessarily indicative of the results that were
reported for the entire fiscal year ending February 28, 1998.

NOTE 3--MERGERS AND ACQUISITIONS

  MERGERS

     Westower Holdings Ltd.  Concurrent with its incorporation in June 1997, the
Company completed a merger with Westower Holdings Ltd. by issuing 3,000,000
shares of common stock in exchange for all outstanding common stock of Westower
Holdings Ltd. Westower Holdings Ltd. is a Wyoming corporation

                                      F-23

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

that owns all outstanding common stock of Westower Communications Ltd. and
Westower Communications, Inc. The merger qualified as a tax-free exchange and is
accounted for similar to a pooling-of-interests.

     WTC Holdings, Inc. and Western Telecom Construction Ltd.  Effective October
28, 1997, the Company completed a merger with WTC Holdings, Inc. (formerly
411677 Alberta Ltd.) and its wholly owned subsidiary, Western Telecom
Construction Ltd., (collectively, "Western Telecom"). WTC Holdings, Inc. was
wholly-owned by a relative of a significant stockholder and a director of
Westower Corporation. WTC Holdings, Inc. is a Wyoming corporation, and Western
Telecom Construction Ltd. is a Canadian corporation. Western Telecom engages in
operations similar to those of the Company. The merger was effected by
exchanging 835,000 shares of common stock for all outstanding common stock of
Western Telecom. The merger qualified as a tax-free exchange and has been
accounted for using the pooling-of-interests method for business combinations.
Accordingly, the consolidated financial statements for the fiscal years ended
February 29, 1996 and February 28, 1997 and 1998 and the Transition Period have
been restated to include the combined financial position, results of operations,
and cash flows of Western Telecom.

     MJA Communications Corporation.  Effective May 31, 1998, the Company
completed a merger with MJA Communications Corporation ("MJA"). MJA is a Florida
corporation which engages in operations similar to those of the Company. In
connection with the merger, MJA's tax status was changed from an S corporation
to a C corporation. The merger was effected by exchanging 397,000 shares of
common stock for all outstanding common stock of MJA. The merger qualified as a
tax-free exchange and has been accounted for using the pooling-of-interests
method for business combinations. Accordingly, the consolidated financial
statements for the fiscal years ended February 29, 1996 and February 28, 1997
and 1998 and the Transition Period have been restated to include the combined
financial position, results of operations, and cash flows of MJA.

     Standby Services, Inc.  Effective August 31, 1998, the Company completed a
merger with Standby Services, Inc. ("Standby"). Standby is a Texas corporation
which engages in operations similar to those of the Company. In connection with
the merger, Standby's tax status was changed from an S corporation to a C
corporation. The merger was effected by exchanging 544,000 shares of common
stock for all outstanding common stock of Standby. The merger qualified as a
tax-free exchange and has been accounted for using the pooling-of-interests
method for business combinations. Accordingly, the consolidated financial
statements for the fiscal years ended February 29, 1996 and February 28, 1997
and 1998 and the Transition Period have been restated to include the combined
financial position, results of operations, and cash flows of Standby.

     Prior to the respective mergers, Western Telecom had a fiscal year-end of
January 31 and MJA and Standby had a fiscal year end of December 31. In
recording the business combinations, the fiscal years ended 1998 and 1997
financial statements have not been restated to conform with Westower
Corporation's previous fiscal year end of February 28, as the effect on the
consolidated financial statements is not material. As a result of Western
Telecom, MJA and Standby having a different fiscal year end and the change in
the Company's fiscal year end, Western Telecom and MJA and Standby's results of
operations for the respective one and two-month periods ended February 28, 1998
have been excluded from the reported results of operations in the Transition
Period and, therefore, have been presented as an adjustment to the Company's
consolidated statement of stockholders' equity for the Transition Period.
Aggregate revenues, expenses, income before extraordinary items and net income,
attributable to these mergers, which have been excluded from the Company's
reported results of operations in the Transition Period, were $3,302,000,
$2,864,000, $438,000 and $438,000, respectively, for the period from January 1,
1998 to February 28, 1998.

  ACQUISITIONS

     The following acquisitions have been accounted for using the purchase
method of accounting for business combinations and, accordingly, the operating
results of the acquired companies have been included in the Company's
consolidated financial statements from the date of acquisition.

     Acquisitions from November 1, 1997 to February 28, 1998.  On dates ranging
between November 1, 1997 and January 17, 1998, the Company acquired all
outstanding shares of common stock of National Tower Service Ltd., 501053 B.C.
Ltd., and the minority interest in WTC Leasing Ltd. which are Canadian
corporations with operations similar to those of the Company. Additionally, on
January 17, 1998 the Company acquired the assets, principally communication
towers, of Ralph's Radio, Inc. and 344813 Alberta Ltd. The aggregate purchase
price of these transactions totaled approximately $2.7 million which consisted

valued at approximately $1.2 million, based on the publicly traded price.

     Jovin Communications, Inc. and Acier Filteau, Inc.  On June 12, 1998 the
Company completed the acquisitions of Jovin Communications, Inc. ("Jovin") and
Acier Filteau, Inc. ("Acier"), both Montreal, Quebec (Canada) corporations which

effected by exchanging shares of common stock of the Company and shares of a
separate class of common stock of an acquisition subsidiary, with rights
identical to those of the Company's common stock, aggregating 118,000 shares in
total and valued at approximately $2.8 million, based on the publicly traded
price, and the assumption of certain obligations of Jovin and Acier, for all

$5 million in cash and the assumption of certain obligations of Cord for all
outstanding common shares of Cord. The former stockholders of Cord may also
receive an additional 348,000 shares of common stock, based on the attainment of
certain performance measures of Cord during the twelve month period following
the date of acquisition. Additional shares of common stock will be recorded as
an adjustment of the purchase price and will increase recorded goodwill.

     CNG Communications, Inc.  On September 28, 1998, the Company completed the
acquisition of CNG Communications, Inc. ("CNG") for approximately $1.7 million
in cash and the assumption of certain obligations of CNG. The former shareholder
of CNG may also receive up to an additional $3 million in cash pending the
successful acquisition of certain wireless communication towers under an
existing contract held by CNG. As part of the acquisition, the Company assumed
certain liabilities of CNG, including convertible debentures, outstanding
warrants and the termination costs relating to a financing agreement with a
third party investment banker. The Company entered into a settlement agreement
with the above parties that resulted in an aggregate payment of $3.25 million to
the convertible debenture holders, which included principal and interest, and
the third party investment banker. On October 22, 1998, the Company exercised
its right to acquire the wireless communication towers under contract at an
exercise price of $9.2 million. The consummation of the acquisition is subject
to regulatory approval.

     The following is a summary of all consideration exchanged for acquisitions
that were accounted for as purchases:

  CONVERTIBLE NOTE

     In June 1998, the Company issued a private placement of $15.0 million of 7%
convertible senior subordinated note (the "Convertible Debt") and warrant to
purchase 40,000 shares of common stock in exchange for $14.85 million net cash
proceeds. The Convertible Debt was immediately convertible at a ratio of $25.03
per share of common stock and the warrant provides for purchase of shares at
$23.00 per share of common stock at the holder's option. The purchase agreement
provides for an adjustment of the conversion amount for the subordinated debt
and warrant exercise price for any stock dividends, splits and other changes as
defined in the respective agreements, so as to preserve the Convertible Debt
holder's relative rights. The conversion ratio and warrant exercise price per
common share were less than the fair value of the Company's common stock at the
date of issuance. The value of the conversion features was approximately
$124,000 and was immediately charged to interest expense and an increase in
additional paid-in capital. The value ascribed to the warrant of approximately
$723,000, was reflected as both a debt discount and an increase in additional
paid-in capital. The debt discount is accounted for as a component of interest
expense using the effective interest rate method.

     The Convertible Debt requires quarterly interest payments through April 30,
2005, when the Company will be required to make principal payments of $3 million
each April 30 and October 31 thereafter through the final maturity date, April
30, 2007. The Company may begin making optional prepayments of the Convertible
Debt beginning May 30, 2000 subject to a certain minimum trading price of the
Company's common stock commencing on or after April 30, 2000. The Company is
subject to various affirmative and negative covenants contained in the
agreement, including minimum net worth and earnings requirements, and
limitations on additional indebtedness, asset disposals and asset additions. The
agreement required the holder of the Convertible Debt to consent to
subordination of the obligation to senior bank indebtedness discussed below. On
September 30, 1998, the Company was in compliance with all covenants with the
exception of the certain indebtedness covenant, which was cured subsequent to
year end. The Company has received a waiver from the note holder waiving the
right to demand repayment of the note as a result of the violation.

  CREDIT FACILITY

     Under terms of a revolving credit facility, dated June 9, 1998 and expiring
April 25, 2005, with a consortium of U.S. and non-U.S. banks, the Company may
borrow up to $75.0 million. The credit facility provides for interest only
payments through August 30, 2000, with escalating principal reductions each
three months from that date through maturity. Borrowings under the credit
facility bear interest at optional rates as specified in the agreement, subject
to the Company's election at the borrowing date. The Company is also required to
pay quarterly commitment fees of .5% on the average undrawn balance of the
credit facility, which is included as a component of interest expense. There
were no borrowings under the credit facility at September 30, 1998. Subsequent
to year end, the Company has drawn approximately $24.0 million on the

credit facility to finance business acquisitions, including the repayment of
acquired subsidiary debt, and to fund operations. Covenants of the credit
facility require the Company to maintain certain debt-to-earnings and interest
coverage ratios. Other provisions limit capital expenditures, subsidiary
indebtedness and require certain minimum levels of earnings and net worth. On
September 30, 1998, the Company was in compliance with all covenants with the
exception of the certain indebtedness covenant, which was cured subsequent to
September 30, 1998. The Company has received a waiver from the lenders waiving
their right to demand repayment of the credit facility as a result of this
violation.

     Undistributed earnings of the Company's Canadian subsidiaries amounted to
approximately $5.7 million at September 30, 1998. Essentially all of those
earnings are considered to be indefinitely reinvested and, accordingly, no
provision for U.S. federal and state income taxes has been provided thereon.
Upon distribution of those earnings in the form of dividends or otherwise, the
Company would be subject to both U.S. income taxes, net of foreign tax credits,
and withholding taxes payable in Canada.

     The tax effects of temporary differences that give rise to deferred tax
assets and liabilities are as follows:

     At September 30, 1998, 342,000 weighted-average shares associated with the
Convertible Debt discussed in Note 8 were excluded from the computation of
diluted earnings per share for the Transition Period because their inclusion
would have had an anti-dilutive effect on earnings per share. All other
potential common shares have been included in the diluted earnings per share
calculation. All potential common shares were included in the calculation of
diluted earnings per share for the years ended February 29, 1996 and February
28, 1997 and 1998.

NOTE 11--STOCKHOLDERS' EQUITY

  REDEEMABLE PREFERRED STOCK

     During the year ended February 28, 1998, the Company merged with WTC
Holdings Ltd. and its wholly-owned subsidiary, Western Telecom Construction Ltd.
(collectively, "Western Telecom"). The merger was accounted for as a
pooling-of-interests and the February 28, 1997 financial statements have been
restated to include the accounts of Western Telecom. In February 1994, Western
Telecom issued 467 shares of Class A redeemable preferred stock. The preferred
stock ranked in priority to common stock in the event of liquidation,
dissolution or winding up of the affairs of Western Telecom. The shares also
contain stated redemption values and rights to 5% noncumulative dividends when
declared by the Board of Directors. There were no unpaid dividends at February
28, 1997 and 1998. The preferred stock has no voting rights.

     The shares have been reflected at their total redemption price of $450,000
in the February 28, 1997 balance sheet. During the year ended February 28, 1998,
the Company redeemed all outstanding shares.

  COMMON STOCK

     The Company has a single class of $0.01 par value common stock. Authorized
shares total 10 million, of which 2,580,000 have been registered on Form SB-2
with the Securities and Exchange Commission under the 1933 Securities Act. A
total of 1,200,000 of the registered securities were sold in connection with an
initial public offering on October 15, 1997. Proceeds from the offering totaled
$7.5 million, net of $485,000 of underwriting costs.

     As disclosed in Note 3, an additional 1,277,000 shares were issued in
connection with various business combinations during the Transition Period and
an additional 3,969,000 shares were issued in the fiscal year ended February 28,
1998. During the fiscal year ended February 28, 1998, a total of 7,000 shares
were issued as stock awards to employees of the Company and acquired businesses
as incentive to remain in the employ of the Company.

  STOCK WARRANTS

     In connection with its initial public offering in October 1997, the Company
issued stock warrants to purchase 1,380,000 shares of common stock of the
Company with an exercise price of $9.00 per share. The warrants contained a
provision whereby the Company could call for redemption of the warrants if the
closing price of the Company's common stock equaled or exceeded $15.00 for ten
consecutive days. During the Transition Period 559,000 warrants to purchase
559,000 shares of common stock were tendered for exercise with aggregate
proceeds of $4.79 million to the Company, net of commissions and related
expenses of $243,000. On September 29, 1998, the Company exercised its right to
call the remaining warrants, with a redemption date of October 30, 1998.
Subsequent to September 30, 1998 and prior to the redemption date, 819,000
warrants were tendered for conversion with gross proceeds of $7.37 million,
resulting in the cancellation of the remaining warrants which were not tendered.

NOTE 12--STOCK OPTIONS

     The Company has two stock option plans that provide for the granting of
stock options to certain officers, employees, directors and consultants of the
Company and its subsidiaries. These options generally vest over a period of
three years from the date of grant (as determined by the Company's Compensation
Committee) and have a maximum exercise term of ten years from the date of grant.
The 1998 Stock Incentive Compensation Plan (the "1998 Plan") is the only plan
with stock option awards currently available for grant; a prior plan has stock
options exercisable at September 30, 1998 to purchase up to 400,000 shares of
common stock. The Company is authorized to grant options for up to ten percent
of the issued shares of common stock under the 1998 Plan. A summary of awards
granted under the plans is as follows for the fiscal year ended February 28,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The Company applies the accounting provisions of APB Opinion No. 25,
Accounting for Stock Issued to Employees, and related interpretations for its
stock-based plans. Accordingly, costs for employee stock options or issuance of
shares is measured as the excess, if any, of the fair value of the Company's
common stock at the measurement date over the amount the employee must pay to
acquire the stock. The cost is recognized ratably by the Company as compensation
expense over the vesting period. The expense for the fiscal year ended February
28, 1998 and the Transition Period was $21,000 and $35,000 respectively.

     The Company adopted the disclosure provisions of SFAS No. 123, Accounting
for Stock-Based Compensation ("SFAS No. 123"), which was effective as of January
1, 1996. The fair value of each option was estimated on the date of grant using
the Black-Scholes option pricing model and the following assumptions:

NOTE 14--RETIREMENT PLAN

     The Company's subsidiary, Westower Communications Inc., adopted a defined
contribution retirement plan, effective January 1, 1997. The plan contains
certain participation criteria and allows for both employee and employer
discretionary contributions. The total Company funded discretionary contribution
for the years ended February 29, 1996 and February 28, 1997 and 1998 was $0,
$46,000 and $52,000, respectively. There were no employer contributions during
the Transition Period.

NOTE 15--RELATED PARTY TRANSACTIONS

  ADVANCE TO RELATED PARTIES

     During the fiscal year ended February 28, 1998, the Company advanced
$119,000 to a Canadian corporation owned by certain stockholders of Westower
Corporation. Proceeds were used by the Corporation to purchase facilities leased
by two of the Company's subsidiaries. The advance was repaid during the
Transition Period. The Company also advanced $77,000 to several stockholders
during the fiscal year ended February 28, 1998 which were repaid during the
Transition Period. At September 30, 1998, additional related party advances
include $379,000 of unsecured non-interest bearing shareholder loans made by
subsidiaries, prior to acquisition, during the Transition Period which are
expected to be paid in full subsequent to September 30, 1998. At September 30,
1998, the Company has a $65,000 receivable from a former shareholder of an
acquired S corporation. The acquired S corporation made a distribution to the
shareholder, prior to the combination, in an amount to meet the shareholder's
current estimated tax obligation. Subsequent to the combination it was
determined that the tax liability was approximately $65,000 overestimated and a
receivable for the excess distribution has been recorded.

  NOTE RECEIVABLE

     At September 30, 1998, the Company had a note receivable for $495,000, plus
accrued interest of $17,000, from an organization with which they share a common
director. The note bears interest at 12% and is collateralized by warrants to
purchase shares of the Company's common stock, and is due on demand.

  MANAGEMENT SERVICES AND ACCOUNTS PAYABLE

     In prior years the Company received consulting services from Westower
Consulting Ltd., a Canadian corporation owned by a stockholder of Westower
Corporation. Charges for these services were $94,000 and $126,000 in the fiscal
years ended February 28, 1997 and 1998, respectively. Included in trade accounts
payable at February 28, 1998 is $39,000 due to Westower Consulting Ltd. Fees
billed by related entities generally do not continue subsequent to acquisition
by the Company as the related services are performed by employees and officers
of the Company.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  LITIGATION

     The Company is subject to lawsuits and other legal claims in the normal
course of its operations. Management believes that the resolution of any such
lawsuits and legal claims, if any, will not have a material impact on the
Company's financial position, results of operations or cash flows.

NOTE 17--CREDIT RISK AND BUSINESS CONCENTRATIONS

     Financial instruments that potentially subject the Company to
concentrations of credit consist primarily of cash, cash equivalents and trade
accounts receivable. The Company places its temporary cash investments with a
major financial institution. At times, deposits with any one institution may
exceed federally insured limits. The Company extends credit to customers based
on evaluation of customer's financial condition and credit history. Collateral
is generally not required. Customers include large Canadian and U.S. companies
concentrated in the telecommunications industry.

     Contract revenues from two customers accounted for 29% of revenues during
the fiscal year ended February 28, 1998, and one customer accounted for 56% of
revenues during the fiscal year ended February 28, 1997. Accounts receivable
from two customers comprise 48% of accounts receivable at February 28, 1998 and
one customer accounted for 39% of account receivable at February 28, 1997. There
were no customers who accounted for greater than 10% of sales for the Transition
Period and there were no customers with accounts receivable representing 10% or
more of the total accounts receivable at September 30, 1998.

     Management expects that sales to relatively few customers will continue to
account for a high percentage of its revenues into the foreseeable future and
believes the Company's financial results depend in significant part upon the
success of these customers. Although the composition of the group comprising the
Company's largest customers may vary from period to period, the loss of a
significant customer or reduction in orders by any significant customers,
including reductions due to market, economic or competitive conditions in the
wireless communications industry, may have an adverse effect on the Company's
business, financial condition and results of operations.

NOTE 18--SEGMENT INFORMATION

     The Company's operations are comprised of a number of communication tower
construction entities that were recently acquired. While management assesses the
operating results of each of these entities separately, as these entities and
its existing operations exhibit similar financial performance and have similar
economic characteristics, they have been aggregated as one segment.

     The following table summarizes contract and other revenues and long-lived
assets related to the respective countries in which the Company operates.

payable, and other current liabilities approximate their carrying amounts. The
fair values of advances to and from related parties approximate their fair value
due to the short term nature of the instruments. The fair values of long-term
debt, which are based on the present values of the underlying cash flows
discounted at the Company's incremental borrowing rates, are as follows:

NOTE 20--SUBSEQUENT EVENTS

     On November 10, 1998 the Company completed the acquisition of Summit
Communications, LLC ("Summit"), a Mississippi limited liability company which
engages in operations similar to those of the Company. The merger was effected
by exchanging 200,000 shares of common stock valued at approximately $4.1
million, based on the publicly traded price, $4.4 million in cash, and the
assumption of certain liabilities, for all membership interests in Summit. The
former members of Summit may also receive an additional 100,000 shares of common
stock, based on certain performance criteria during the three years following
the date of acquisition. The acquisition was accounted for using the purchase
method for business combinations resulting in goodwill of approximately $8.0
million.

     On October 30, 1998 the Company completed the acquisition of Teletronics
Management Services, Inc. ("Teletronics"). The acquisition was effected by
exchanging 188,000 shares of common stock valued at approximately $4 million,
based on the publicly traded price, $1 million in cash, and the assumption of
certain liabilities including distributions payable to former shareholders in
the amount of $800,000, for all outstanding shares of Teletronics. The
acquisition was accounted for using the purchase method for business
combinations resulting in goodwill of approximately $5.0 million.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors
CORD Communications, Inc.

     We have audited the accompanying balance sheets of CORD Communications,
Inc. as of June 30, 1998 and 1997, and the related statements of operations,
changes in stockholders' equity (deficit), and cash flows for the years then
ended. 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 audits 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 CORD Communications, Inc. as
of June 30, 1998 and 1997, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

     As described in note 13 to the financial statements, the Company was sold
subsequent to June 30, 1998.

                         NOTES TO FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  NATURE OF OPERATIONS

     CORD Communications, Inc. was incorporated in July 1994 in the state of
California. The Company constructs cellular communication sites, underground and
overhead telephone and utility lines, and commercial tenant improvements. In
addition, they perform site acquisition and lease negotiations, and provide land
use planning services. The Company operates primarily in California, Washington,
and Oregon.

  CASH AND CASH EQUIVALENTS

     For purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with an original maturity of three
months or less to be cash equivalents. At June 30, 1997, cash and cash
equivalents that exceeded the FDIC insurance limits were $711,410.

  ACCOUNTS RECEIVABLE

     In the normal course of business, the Company extends credit to customers,
principally with customers located in California, Washington, and Oregon.
Collectibility of accounts receivable is periodically assessed by management.
This assessment provides the basis for any allowance for doubtful accounts and
related bad debt expense. An allowance of $83,000 was considered necessary by
management at June 30, 1998. No allowance for doubtful accounts was considered
necessary by management as of June 30, 1997. A concentration of credit risk
exists in connection with the Company's trade customers due to the proximity of
location and services provided. As of June 30, 1998 and 1997, the Company had
accounts receivable balances of $1,951,901 and $2,452,205, which were exposed to
the concentration of credit risk. Credit risk related to contract receivables is
minimized by the Company's rights under lien laws on contracts subject to those
laws.

  REVENUE AND COST RECOGNITION

     Revenues from fixed-price construction contracts are recognized on the
percentage of completion method, measured on the basis of cost incurred to date
to total estimated cost for each contract. Because of inherent uncertainties in
estimating cost to complete, it is at least reasonably possible that the
estimates used will change in the near term.

     Contract costs include all direct material, equipment and labor costs,
subcontract costs and those indirect costs related to contract performance, such
as supplies, travel and per diem costs. General and administrative costs are
charged to expense as incurred. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined. Changes in
job performance, job conditions, and estimated profitability, including those
arising from final contract settlements, may result in revisions to costs and
income and are recognized in the period in which the revisions are determined.
Claims are generally included in contract revenues when settled.

     The asset, "Cost and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in advance of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts," represents billings in advance of revenues recognized.

  PROPERTY AND EQUIPMENT

     Property and equipment is carried at cost and is depreciated on the
straight-line method over the estimated useful lives of the assets.

</TABLE>

     The cost and related accumulated depreciation of assets sold or disposed
are removed from the accounts, and any resulting gain or loss is included in
operations. Repairs and maintenance expenditures are expensed as incurred.

  INCOME TAXES

     Income taxes are provided for the tax effects of transactions reported in
the financial statements, and consist of taxes currently due plus deferred taxes
related primarily to different methods of accounting for depreciation and the
use of the cash method for income tax purposes. The deferred taxes represent the
future tax return consequences of those differences, which will either be
taxable or deductible when the assets and liabilities are recovered or settled.

  USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

     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 financial statements and
accompanying notes. Actual results could differ from those estimates.
Significant estimates used in preparing these financial statements include
estimated costs to complete which have a direct effect on gross profit.

  VALUATION OF LONG LIVED ASSETS AND CHANGE IN ACCOUNTING POLICY

     The Company periodically reviews long-lived assets and certain identifiable
intangibles whenever events of changes in circumstance indicate that the
carrying amount of an asset may not be recoverable. There will be no provisions
for impairment during 1998 or 1997.

8.  BOND GUARANTEES

     Most of the Company's business activities are performed under contract
agreements with customers which require bond guarantees from an independent
surety company. As is customary in the construction industry, the Company has
pledged all of its assets in order to indemnify the surety company against
losses under these bond guarantees.

9.  RELATED PARTY TRANSACTIONS

     During the year ended June 30, 1996, the Company bought back 418 shares of
its stock which was owned by a principal stockholder. The buy-back of stock was
accomplished by providing an unsecured promissory note for $138,063 payable upon
demand, which accrued interest at the rate of 10% per annum. During the year
ended June 30, 1998, the Company paid the remaining principal balance
outstanding at June 30, 1997 of $87,402.

     The Company leases equipment from a principal stockholder. Lease payments
for the years ended June 30, 1998 and 1997 were $57,600 and $78,920,
respectively. Amounts included in accounts payable that were due to the
stockholder for equipment rental were $0 and $22,200 at June 30, 1998 and 1997,
respectively.

     On June 30, 1995, the Company had an outstanding unsecured note receivable
from a stockholder, which it had received in exchange for the issuance of common
stock. The note is payable upon demand and accrues interest at the rate of 10%
per annum. The Company received payments of principal and interest of $0 and
$30,820 at June 30, 1998 and 1997, respectively. The remaining principal balance
owed the Company at June 30, 1998 and 1997 was $60,598. The Company's accrued
interest balance at June 30, 1998 and 1997 was $14,410 and $7,744, respectively.

10.  DEFINED CONTRIBUTION PENSION PLAN

     Effective January 1997, the Company adopted a 401(k) retirement plan that
covers all employees who have completed one year of service and are at least 21
years of age. The Company's contributions, which are discretionary, are
allocated to participants based on a percentage of wages. Participants may also
make elective contributions. Employer pension expense for the year ended June
30, 1998 and 1997 totaled $28,409 and $0, respectively.

11.  DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following methods and assumptions were used by the Company in
estimating its fair value disclosures for financial instruments:

     Cash, accounts receivable, accounts payable, and other current
liabilities--At June 30, 1998, carrying amounts of these financial instruments
approximate fair value because of their short maturities.

     Long term debt and capital lease obligations--At June 30, 1998, estimated
fair value of long-term debt approximates the carrying amount of $92,663, based
on current rates offered for similar debt.

12.  YEAR 2000 COMPLIANCE

     The Company is conducting a review of its computer and other systems to
identify those areas that could be affected by the "Year 2000" issue and is
developing an implementation plan to resolve the issue. The Company is currently
working with consultants who believe, with modifications to existing software
and converting to new software and hardware, the Year 2000 problem will not pose
significant operational problems and is not anticipated to be material to its
financial position or results of operations in any given year.

13.  SUBSEQUENT EVENTS

     On September 1, 1998, the Company's line of credit was paid in full and
canceled.

     On August 31, 1998, the stockholders of CORD Communications sold all of the
outstanding shares of stock to Westower Corporation in exchange for $5,000,000
in cash and 217,389 shares of Westower stock. The stockholders can receive
347,826 additional shares contingent on the performance of CORD Communications
during the twelve months following the purchase. The purchase agreement also
provides that Westower will support CORD's need for additional working capital
during the twelve months following the purchase. Westower is a larger cellular
tower contractor and operator, and is planning to bring its additional
marketing, operational and capital resources to CORD Communications in order to
grow and enhance the Company's business activities.

management, as well as evaluating the overall financial statement presentation.
We believe our audit provides 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 Summit Communications, LLC
as of December 31, 1997, the results of its operations and its cash flows for
the Period of Inception (May 24, 1997) to December 31, 1997, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
        FOR THE PERIOD OF INCEPTION (MAY 24, 1997) TO DECEMBER 31, 1997
                  AND THE NINE MONTHS ENDED SEPTEMBER 30, 1998

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Organization

     Summit Communications LLC (the "Company") is incorporated under the laws of
the state of Mississippi as a limited liability company (LLC). The Company
constructs communications towers for use by the radio, television, telephone and
other industries in the continental United States.

  Accounting 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. Examples of estimates subject to possible revision based upon
the outcome of future events include costs and estimated earnings on uncompleted
contracts and depreciation on property and equipment. Actual results could
differ from those estimates.

  Revenue and Cost Recognition

     Revenues from fixed-priced and modified fixed-price construction contracts
are recognized on the percentage-of-completion method, measured by the
percentage of costs incurred to date to total estimated costs to complete each
contract. Most of the Company's contracts are short-term and are completed in
two to three months.

     Contract costs include all direct material and labor costs and those direct
costs related to contract performance, such as supplies, tools and repairs.
Selling, general and administrative costs, including indirect costs on
contracts, are charged to expense as incurred. Provisions for estimated losses
on uncompleted contracts are made in the period in which such losses are
determined.

     Costs and estimated earnings in excess of billings on uncompleted contracts
represents revenues recognized in excess of amounts billed. Billings in excess
of costs and estimated earnings on uncompleted contracts represents billings in
excess of revenues earned.

  Property and Equipment

     Property and equipment is recorded at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets.
Estimated useful lives by major asset category are as follows: machinery and
equipment--2 to 10 years; vehicles--3 to 5 years; furniture and fixtures--3 to 7
years. Gains or losses on the dispositions of assets are recorded at the time of
disposition and are included in other income. The costs of normal repairs and
maintenance are charged to expense as incurred.

  Income Taxes

     Income of the Company is taxed directly to its members for Federal income
tax purposes. As a result, no provision for Federal income taxes has been
reflected in the accompanying financial statements.

  Reclassifications

     Certain reclassifications have been made to prior year amounts to conform
with current year presentation. These reclassifications had no effect on
previously reported results of operations, net assets, cash flows or members'
equity.

7.  EMPLOYEE BENEFIT PLAN

     The Company has a defined contribution employee benefit plan, which is the
401(k) Profit Sharing Plan and Trust. Employees become eligible for
participation in the plan after one year of service. Employees may contribute a
percentage of their gross compensation not to exceed certain limits.
Contributions by the Company are made at the discretion of the members. There
were no contributions made by the Company related to this plan for the Period of
Inception (May 24, 1997) to December 31, 1997 and for the nine months ended
September 30, 1998.

8.  RELATED PARTY TRANSACTIONS

  NOTE RECEIVABLE

     At September 30, 1998, the Company had a note receivable for $155,000 from
one of its members. The note bears interest at the same rate as the line of
credit, is payable on demand, and is uncollateralized. The note was subsequently
repaid in full.

  SALE OF BUILDINGS

     In February 1998, the Company acquired a building from one of the members
for $500,000. In July 1998 the building was sold to the members resulting in a
loss of approximately $12,000.

                           SUMMIT COMMUNICATIONS, LLC

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

  FACILITY LEASES

     The Company leases space in two buildings owned by the members of the
Company under a month to month operating lease. For the nine months ended
September 30, 1998, total rent paid to the members was approximately $9,300.

9.  CONTINGENCIES

     The Company is subject to lawsuits and other legal claims in the normal
course of its operations. Management believes that the resolution of any such
lawsuits and legal claims, if any, will not have a material impact on the
Company's financial position, results of operations or cash flows.

10.  CREDIT RISK AND BUSINESS CONCENTRATIONS

     Financial instruments that potentially subject the Company to
concentrations of credit consist primarily of cash and accounts receivable. The
Company deposits its cash with a major financial institution. At times, deposits
may exceed federally insured limits. The Company extends credit to customers
based on evaluation of the customer's financial condition and credit history.
Collateral is generally not required. Customers include large U.S. companies
concentrated in the telecommunications industry.

     Contract revenues earned from three customers accounted for 54% of revenues
for the Period of Inception (May 24, 1997) to December 31, 1997. Accounts
receivable from these three customers comprise 53% of accounts receivable at
December 31, 1997. Contract revenues earned from two customers accounted for 58%
of revenues for the nine months ended September 30, 1998. Accounts receivable
from these two customers comprise 57% of accounts receivable at September 30,
1998.

     Management expects that sales to relatively few customers will continue to
account for a high percentage of its revenues into the foreseeable future and
believes that financial results depend in significant part upon the success of
these customers. Although the composition of the group comprising the Company's
largest customers may vary from period to period, the loss of a significant
customer or reduction in orders by any significant customers, including
reductions due to market, economic or competitive conditions in the wireless
communications industry, may have an adverse effect on the Company's business,
financial condition and results of operations.

Westower common stock based upon certain performance criteria during the three
years subsequent to the date of acquisition. The purchase agreement also
provides that Westower will supply the Company's need for additional working
capital following the purchase.

     On May 15, 1999, Westower entered into a definitive agreement with
SpectraSite Holdings, Inc. (SpectraSite), under which Westower will merge with a
subsidiary of SpectraSite. The transaction was consummated on September 2, 1999
and under the terms of the agreement, Westower shareholders received 1.81 shares
of SpectraSite common stock for each Westower share.

                       UNAUDITED PRO FORMA FINANCIAL DATA

GENERAL

     The unaudited pro forma financial data are based on the historical
financial statements of SpectraSite and Westower and the adjustments described
in the accompanying notes. The unaudited pro forma financial data do not purport
to represent what SpectraSite's, Westower's or the combined entity's financial
position or results of operations would actually have been if the transactions
had in fact occurred on the dates indicated and are not necessarily
representative of SpectraSite's financial position or results of operations at
any future date or for any future period.

SPECTRASITE

     The following unaudited pro forma consolidated financial data present both
the pre-merger and post-merger unaudited pro forma consolidated statements of
operations of SpectraSite for the year ended December 31, 1999. The SpectraSite
pro forma column and the Westower pro forma column presented in the post-merger
SpectraSite unaudited pro forma consolidated statement of operations for the
year ended December 31, 1999 are derived from the pre-merger SpectraSite and
Westower pro forma consolidated statements of operations for the corresponding
periods. The unaudited pro forma consolidated statement of operations data give
effect to the following transactions as if they had occurred on January 1, 1999:

     - the acquisition of 2,000 communications towers from Nextel, the leaseback
       of antenna space by Nextel and SpectraSite's exclusive agreement to
       acquire or construct 1,700 additional sites for Nextel;

     - the issuance and sale of Holdings' 11 1/4% senior discount notes due
       2009;

     - initial borrowings under SpectraSite's credit facility; and

     - the consummation of the Westower merger.

     Certain of the data presented in the "Nextel" column to the unaudited pro
forma statement of operations of SpectraSite are estimates provided by Nextel.
None of SpectraSite's independent accountants, Nextel's independent accountants
or Westower's independent accountants have audited or otherwise tested this
data. We believe the estimated amounts are factually supported and based on
reasonable assumptions. However, these amounts may not accurately reflect the
results of operations from the Nextel towers for the periods presented or the
operating results that we can expect from the Nextel towers in the future.

     The acquisition of tower assets from Nextel and the leaseback of antenna
space by Nextel are presented as if the purchase of assets had occurred on
January 1, 1999. Adjustments for revenues are based on the terms of the master
site lease agreement and on historical co-location revenues. Adjustments for
costs of operations consist of direct operating expenses, which include ground
lease payments, historical routine maintenance costs and property taxes
associated with the towers. Depreciation expense is straight-line depreciation
of the aggregate cost of the towers. Ground leases are non-cancelable operating
leases, generally for terms of five years and include options for renewal, and
pro forma ground lease expense is based on executed ground leases. Nextel has
leased space on each of the 2,000 towers we acquired, primarily for five-year
terms with options for renewal.

     The pro forma minimum ground lease expenses and minimum rental income for
these leases assuming the Nextel transaction occurred and the related leases
commenced January 1, 1999 are as follows:

WESTOWER

     The following unaudited pro forma consolidated financial data of Westower
present the unaudited pro forma consolidated statement of operations of Westower
for the period from January 1, 1999 through September 2, 1999, the date on which
SpectraSite acquired Westower.

     This statement gives effect to the acquisition of communications towers
from Koch Industries, Inc. and its affiliates, which occurred in February 1999,
as if this acquisition occurred on January 1, 1999. In addition to the above
acquisition, from January 1 through September 2, 1999, Westower acquired Cypress
Real Estate Services, Inc. and Telecommunications R. David. These acquisitions,
which are included in the historical financial statements of Westower, were not
considered significant transactions, individually or in the aggregate, and
therefore, were not included in the unaudited pro forma consolidated statement
of operations of Westower.

     Adjustments for revenues are based on the executed tenant lease terms for
the Koch towers. Adjustments for costs of operations consist of direct operating
expenses, which include ground lease payments, estimated routine maintenance
costs, property taxes and insurance associated with the towers. Depreciation
expense is straight-line depreciation of the aggregate cost of $17.0 million.
The Koch ground leases are non-cancelable operating leases for a term of 49
years, and pro forma ground lease expense is based on executed ground leases.
Koch has leased space on these towers for a ten-year term with options for
renewal. The pro forma minimum ground lease expense and minimum rental income
for these leases assuming the transaction occurred and the related leases
commenced January 1, 1999 are as follows:

                      FOR THE YEAR ENDED DECEMBER 31, 1999
                                 (IN THOUSANDS)

          (a)  Consists of $2,611 of historical co-location revenues received by
     Nextel prior to the acquisition, which are based on fixed payment lease
     terms. This information was provided to us by Nextel. Also consists of
     $12,343 of additional revenues to be recognized by SpectraSite under the
     terms of the Nextel master site lease agreement.

          (b)  Reflects certain direct operating expenses, primarily the cost of
     executed ground leases, historical routine maintenance and property taxes
     associated with the towers, paid by Nextel prior to the acquisition.

          (c)  SpectraSite has incurred incremental operating expenses as a
     result of the Nextel tower acquisition. Such incremental expenses are
     estimated to have been approximately $1,500 per month. These incremental
     operating expenses are based upon management's estimates rather than on any
     contractual obligation; as such, these amounts have not been presented as
     adjustments in the accompanying pro forma financial statements.

          (d)  Reflects the depreciation of the acquired towers calculated on a
     straight-line basis over 15 years.

          (e)  Reflects adjustment to interest expense as if SpectraSite had
     issued its 11 1/4% senior discount notes due 2009 and had entered into the
     credit facility on January 1, 1999 as follows:

       NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS
                      FOR THE YEAR ENDED DECEMBER 31, 1999
                                 (IN THOUSANDS)

     (a)  Reflects the elimination of intercompany site construction revenues
and costs of site construction for towers built by Westower for SpectraSite
during the period from January 1 through September 2, 1999.

     (b)  Reflects amortization of goodwill as if the merger of Westower and
SpectraSite had occurred on January 1, 1999. Goodwill is amortized over 15
years.

     (c)  Reflects adjustments to eliminate amortization of historical goodwill
of Westower of $1,062 and to convert Westower tower depreciation from 20 years
to 15 years, increasing expense by $611.

     (d)  Reflects the elimination of certain non-recurring charges resulting
directly from the transaction which were incurred by Westower prior to its
acquisition by Spectrasite.

     (e)  Reflects an adjustment to eliminate interest income as if SpectraSite
had used cash-on-hand to repay Westower's outstanding indebtedness.

     (f)  Reflects adjustments to eliminate interest expense as if Westower's
credit facility and its $15,000 convertible note from BET Associates were paid
in full on January 1, 1999.

     (g)  SpectraSite's earnings per share for the year ended December 31, 1999
reflects the adoption of Statement of Financial Accounting Standards No. 128,
"Earnings Per Share", which requires companies to compute earnings per share
under two different methods, basic and diluted. The weighted average common
shares outstanding at December 31, 1999 reflects the issuance of 15.5 million
shares of SpectraSite common stock in exchange for all of the outstanding shares
of Westower common stock.

     If SpectraSite had net income during this period, diluted earnings per
share would have included potential common shares related to its convertible
preferred stock and outstanding options. These potential common shares were not
included in the diluted earnings per share calculation for the year ended
December 31, 1999 because the effect would have been antidilutive. In connection
with the Nextel tower acquisition, provisions for dividends and redemption were
eliminated with respect to Holdings' Series A and Series B preferred stock.
