                             PINNACLE HOLDINGS INC.
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. FINANCIAL STATEMENTS

         The accompanying consolidated financial statements reflect the
financial position and results of operations and cash flows of Pinnacle Holdings
Inc. and its wholly owned subsidiaries: Pinnacle Towers Inc., Pinnacle Towers
Canada Inc., Coverage Plus Antenna Systems, Inc. and Tower Systems, Inc. In
addition, beginning in 1999 Pinnacle Holdings Inc. contributed capital to PT III
("PT III") to establish a preferred stock interest. Pinnacle Towers Inc. and
certain members of management of Pinnacle Holdings Inc. own the common stock of
PT III. PT III utilized the capital contributed to purchase certain
communications site assets and the stock of a corporation that owns and manages
communications sites. As a result of Pinnacle Holdings Inc.'s ability to direct
the policies and management that guide the ongoing activities of PT III, the
financial position and results of operations and cash flows of PT III are
consolidated in the financial statements of Pinnacle. Unless otherwise noted,
"we," "us," "our," or "Pinnacle" refers to Pinnacle Holdings Inc. and its
consolidated subsidiaries, including PT III. All significant intercompany
balances and transactions have been eliminated.

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

         Results of operations for any interim period are not necessarily
indicative of results of any other periods or for the year. The consolidated
statements as of March 31, 2000 and for the three month periods ended March 31,
2000 and 1999 are unaudited, but in the opinion of management include all
adjustments (consisting of normal recurring adjustments) necessary for a fair
presentation of results for such periods. These consolidated financial
statements should be read in conjunction with Pinnacle's financial statements
and notes thereto for the year ended December 31, 1999.

2. ACQUISITIONS

         We actively acquires communications sites and related real estate
assets.

         On August 31, 1999, we acquired 1,858 communications sites and related
assets from Motorola, Inc. ("Motorola") for $254 million, comprised of $245
million in cash and $9 million of our common stock, plus fees and expenses of
approximately $17 million (the "Motorola Antenna Site Acquisition"). The
purchase price allocations related to this transaction are preliminary. However,
we do not expect that the final allocation of the purchase price will be
materially different from its preliminary allocation. This acquisition results
in Pinnacle having sites in all 50 states and nine Canadian Provinces. We
transferred certain of the rooftop communication sites we acquired from Motorola
to PT III.

         Included in the total purchase price recorded on a preliminary basis
for the Motorola acquisition were accrued costs related to completion of the
transaction of approximately $31.5 million. These accrued deal costs were
comprised primarily of employee severance and relocation costs ($1.7 million),
contract and title work related to communications sites, due diligence and
closing costs ($29.8 million). As of March 31, 1999, approximately $21.0 million
of these accrued costs had been paid by us.

         In addition to the Motorola Antenna Site Acquisition, during the year
ended December 31, 1999 we completed 129 acquisitions of 442 communications
sites and related assets, each of which was individually insignificant to
Pinnacle, from various sellers for an aggregate purchase price of $238 million
consisting of $228 million in cash and $10 million of notes payable to the
former communications site owners.

                                       5
<PAGE>

         During the three months ended March 31, 2000, we completed 65
acquisitions of 668 communications sites and related assets, each of which was
individually insignificant to Pinnacle, from various sellers for an aggregate
purchase price of $176.3 million consisting of $169.0 million in cash and $7.3
million of notes payable to the former communications site owners.

         We account for our acquisitions using the purchase method of
accounting. The results of operations of the acquired assets are included with
those of Pinnacle from the dates of the respective acquisitions. The pro forma
results of operations listed below reflect purchase accounting and pro forma
adjustments as if the transactions occurred as of January 1, 1999. The unaudited
pro forma consolidated financial statements are not necessarily indicative of
the results that would have occurred if the assumed transactions had occurred on
the dates indicated and are not necessarily indicative of the expected financial
position or results of operations in the future.

3.       LONG-TERM DEBT

         As of June 25, 1999, we amended our Senior Credit Facility to provide
$520 million of financing, of which $470 million was committed. Advances under
the Senior Credit Facility accrue interest at our option of either LIBOR plus a
margin of up to 3.00%, as defined in the related agreement, or at the greater of
the Federal Funds Effective Rate plus 0.50% or the prime rate, plus a margin of
up to 1.75%. Additionally, certain financial covenants were modified.

         As of September 17, 1999, we again amended our Senior Credit Facility
to provide $670 million of financing, of which $520 million was committed and
$290 million was utilized at March 31, 2000.

         The Senior Credit Facility is secured by a lien on substantially all of
our assets and a pledge of substantially all of the capital stock of our
subsidiaries. The Senior Credit Facility contains customary covenants such as
limitations on our ability to incur indebtedness, to incur liens or encumbrances
on assets, to make certain investments, to make distributions to stockholders,
or prepay subordinated debt. Under the Senior Credit Facility, we may not permit
the ratio of senior debt to annualized EBITDA as defined in the agreement to
exceed certain amounts.

         On March 22, 2000 we completed a private placement of $200 million of
5.5% Convertible Subordinated Notes Due 2007 (the "Convertible Notes") to
certain institutional purchasers pursuant to the exemption from registration
provided by Section 4(2) of the Securities Act. We repaid outstanding
revolving debt under our Senior Credit Facility with the net proceeds of $193.5
million from this private placement. We will pay interest on the Convertible
Notes on March 15 and September 15 of each year, with the first interest payment
to be made September 15, 2000. The Convertible Notes will mature on September
15, 2007 unless previously redeemed or repurchased. The Convertible Notes are
convertible into Pinnacle's common stock at the option of the Convertible Note
holders at an initial price of $78.375 per share, which conversion price is
subject to adjustment under the terms of the Convertible Notes. We may redeem
the Convertible Notes on or after March 21, 2003. Pursuant to a Registration
Rights Agreement dated March 22, 2000, we must use reasonable best efforts to
file a registration statement on or before June 20, 2000, to cover resales of
the Convertible Notes and the shares of Common Stock issuable upon conversion
of the Convertible Notes.

4. PUBLIC OFFERINGS AND STOCKHOLDERS' EQUITY

         INITIAL PUBLIC OFFERING

         On February 19, 1999, we completed our initial public offering of our
common stock ("the Offering") whereby we sold 20,000,000 shares of a new class
of common stock (the "Common Stock"). In addition, on March 19, 1999, the
Underwriters over-allotment options were exercised to the extent that an
additional 2,026,000 shares were sold. The initial price per share was $14,
resulting in net proceeds from the Offering of approximately $288 million.

         In connection with the Offering, pursuant to a recapitalization
agreement between Pinnacle, our largest stockholder, ABRY Broadcast Partners II,
L.P. ("ABRY II"), and certain members of our management that are stockholders of
Pinnacle, we converted all outstanding shares of each class of Pinnacle's five
classes of common stock into shares of the Common Stock sold in the Offering and
paid to the holders of certain of such classes of common stock preferential
amounts and yields. Pinnacle's certificate of incorporation was amended
immediately prior to the consummation of the Offering to eliminate the multiple
classes of Pinnacle's common stock and create the now single class of Common
Stock, and all of the outstanding shares of all the classes of common stock of
Pinnacle other than Class D Common stock were converted into approximately
8,571,309 shares of Common Stock and all shares of Class D common stock were
converted into approximately 1,428,691 shares of Common Stock. All unvested
shares of Class D Common stock held by employees at the date of the Offering
become vested shares.

         The holders of Pinnacle's outstanding (prior to the above described
conversion) shares of Class A Common stock, Class B Common stock and Class E
Common stock were collectively paid approximately $38.9 million by Pinnacle from
proceeds of the Offering, which amount equaled the amount of preferences such
shares were entitled to over the other classes of Pinnacle's common stock
pursuant to our certificate of incorporation before giving effect to the
amendment relative to the conversion of those shares as described above. In
addition, the holders of Pinnacle's outstanding (prior to the above described
conversion) shares of Class A Common stock were collectively paid approximately
$4.8 million by Pinnacle from proceeds of the Offering, which amount equaled the
amount of yield such shares had accrued from the date of their issuances through
June 30, 1997 pursuant to Pinnacle's certificate of incorporation before giving
effect to the amendment relative to the conversion of those shares as described
above.

         Other uses of proceeds from the Offering were: (1) approximately $32.0
redeemed the outstanding shares of Pinnacle's Series A Senior Preferred Stock
(the "Senior Preferred Stock"); (2) approximately $61.7 million redeemed the
outstanding shares of Pinnacle's Series B Junior Preferred Stock (the "Junior
Preferred Stock"); (3) approximately $15.7 million repaid in full and retired
loan from ABRY II; (4) approximately $123.8 million repaid outstanding
borrowings under Pinnacle's Senior Credit Facility; and, (5) $11.4 was used to
fund the closing of pending acquisitions proximate to the date the funds were
available from the Offering.

         SECONDARY OFFERINGS

         On July 27, 1999, we completed a secondary offering of common stock
(the "July Offering") whereby we sold 8,650,000 shares of our common stock. The
price per share was $25, resulting in net proceeds from the July Offering of
approximately $206 million. Certain stockholders of Pinnacle also sold 2,350,000
shares of common stock, the net proceeds of which are not available to us. The
proceeds from the July Offering were invested initially in short-term liquid
securities and were used in conjunction with Pinnacle's availability of senior
debt under our amended Senior Credit Facility to fund acquisitions, the
construction of new communications sites and improvements to existing
communications sites.

         On January 24, 2000, we completed another secondary offering of common
stock (the "January Offering") whereby we sold 7,200,000 shares of our common
stock. The price per share was $41, resulting in net proceeds from the January
Offering of approximately $283 million. Certain stockholders of Pinnacle also
sold 3,150,000 shares of common stock, the net proceeds of which are not
available to us. The proceeds


                                       7
<PAGE>

from the January Offering were invested initially in short-term liquid
securities and will be used to reduce our debt or be used with borrowings made
under the Senior Credit Facility to fund acquisitions, the construction of new
communications sites and improvements to existing communications sites
(approximately $106 million used through March 31, 2000). The total shares sold
included a concurrent exercise of the underwriters' over-allotment option
whereby 1,350,000 shares were sold (including 450,000 shares sold by certain of
our stockholders).

         OTHER ISSUANCES OF STOCK

         In conjunction with the Motorola Antenna Site Acquisition, we issued
418,520 shares of common stock to Motorola as part of the consideration given
for the acquisition. These shares were recorded at the fair value of the
securities when the terms of the acquisition were agreed to and announced.

         During the three months ended March 31, 2000, we issued 46,452 shares
of our common stock upon exercise of various stock options granted to our
employees at the time of the Offering.

4. COMMITMENTS

         As of and subsequent to March 31, 2000, we entered into several letters
of intent with various third parties to purchase 676 communications sites,
reflecting an aggregate commitment to pay approximately $131.4 million, all of
which are subject to consummation of a transaction pending completion of due
diligence efforts and any further negotiation which may result therefrom. In
addition, we have completed acquisitions of 178 communications sites for an
aggregate purchase price of $39.2 million subsequent to March 31, 2000.

OVERVIEW

         We acquire communications sites and construct rental towers and lease
space on these communications sites to a broad base of wireless communications
providers, operators of private networks, government agencies and other
customers. Our objective is to acquire or construct clusters of rental
communications sites in areas where there is significant existing and expected
continued growth in the demand for rental communications sites by wireless
communications providers. We seek to obtain a significant ownership position of
communications site assets in our targeted markets in order to offer "one-stop
shopping" to wireless communications providers who are deploying or expanding
wireless communications networks.

         Our growth has come primarily from the acquisition of communications
sites and construction of towers and from adding new tenants to these towers.
Our business strategy focuses on aggressively pursuing communications site
acquisitions and selectively constructing towers in areas that complement our
existing base of rental communications sites and the expansion into additional
high growth wireless communications markets. Since commencing operations in May
1995, we have completed acquisitions and builds as follows:

--------------
* Does not include 34 communications sites currently managed or leased that were
  acquired between 1995 and 1998.

         Since March 31, 2000, we have closed 19 acquisitions with 178
additional communications sites and, as of May 5, 2000, have agreements or
letters of intent to acquire 676 additional communications sites. In addition,
we have identified numerous additional acquisition candidates. We expect that
internal growth

                                       9
<PAGE>

related to completed acquisitions and the business potential of pending
acquisitions will have a material impact on our future revenues and EBITDA.

         We believe that significant opportunities for growth exist by
maximizing the use of our existing and future communications sites. Because the
costs of operating a communications site are primarily fixed on owned sites,
increasing tower utilization significantly improves tower level operating
margins on these sites. We believe that "same site" revenue growth on owned
communications sites (measured by comparing the annualized run rate revenue of
our owned communications sites at the end of a period to the annualized run rate
revenue for the same owned communications sites at the end of a prior period),
is a meaningful indicator of the quality of these sites and our ability to
generate incremental revenue on such sites. Taking into consideration new leases
written as of December 31, 1999, we experienced "same site" revenue growth of
approximately 19.0% for the year ended December 31, 1999 on the base of
communications sites we owned as of December 31, 1998.

         We have generated net losses since inception and at March 31, 2000, had
an accumulated deficit totaling approximately $136.4 million. Due to the nature
of our business (the leasing of cash-generating assets) and our plans to
continue to grow the business, it is expected that charges relating to
depreciation of existing and future assets and interest expense associated with
related debt balances will be substantial. Accordingly, we expect to continue to
generate losses for the foreseeable future.

         Our annualized run rate revenue is calculated as of a given date by
annualizing the monthly rental rates then in effect for customer lease contracts
as of such date. We believe that growth in our annualized run rate revenue is a
meaningful indicator of our performance. As of March 31, 2000, our annualized
run rate revenue was approximately $160 million.

         On August 31, 1999, we completed the Motorola Antenna Site Acquisition.
In connection with that transaction, we acquired approximately 1,858
communications sites, consisting of approximately 499 owned sites, 526 managed
sites and 833 leased sites, for $254 million in cash and stock, plus fees and
expenses. For the year ended December 31, 1999 on a pro forma basis, the
Motorola sites generated $55.7 million in revenue, $25.6 million in tower level
cash flow and $17.7 million in EBITDA for the eight months ended prior to
closing on August 30, 1999. Previously, we have not had a significant number of
managed or leased sites in our portfolio. Generally, managed and leased sites
have higher operating costs than owned towers, primarily as a result of higher
rental costs related to revenue sharing with site owners. In addition, on leased
sites, we generally have a right to lease only a limited portion of a site,
which limits total revenue potential. Higher relative operating costs and
limited revenue growth results in substantially lower tower cash flow and EBITDA
margin performance on managed and leased sites. Accordingly, the acquisition of
managed and leased sites in the Motorola Antenna Site Acquisition or any
potential future acquisitions will substantially decrease our site level
operating margins.

         Following the closing of the Motorola Antenna Site Acquisition we
transferred a portion of the rooftop communication sites we acquired from
Motorola to PT III, a corporation in which we own substantially all of the
equity interests, in exchange for $9.8 million of convertible preferred stock
and a $39.2 million Convertible Promissory note, in order to minimize the risk
that the ownership of or income from such assets might negatively affect our
qualification as a REIT. We also agreed to make our personnel, facilities and
general and administrative overhead available to PT III, the cost thereof to be
reimbursed to us by PT III. During the quarterly period ended March 31, 2000, we
purchased approximately $2.4 million of additional convertible preferred stock
of PT III and approximately $9.5 of additional convertible promissory notes. PT
III used such funds to acquire all of the stock of a corporation that owns and
manages communications sites, and to acquire certain assets used in
communications site management and related activities. See Item 5, Other
Information.

 THREE MONTHS ENDED MARCH 31, 2000 COMPARED TO THREE MONTHS ENDED MARCH 31, 1999

         Revenues increased by $27.9 million, or 232.5%, to $39.9 million for
the three month period ended March 31, 2000 from $12.0 million for the three
month period ended March 31, 1999. This additional revenue is mainly
attributable to the acquisition and construction of 2,994 sites since January 1,
1999. They are as follows: 671 sites during the first quarter 2000; 2,198 sites
during the last three quarters of 1999 which includes the Motorola Antenna Site
Acquisition; and 125 sites during the first quarter of 1999. A portion of the
revenue increase is related to same-site organic growth. Same-site organic
growth is a result of expanded marketing efforts to increase the number of
customers per site, renegotiating leases that are subject to renewal, and,
contractual price escalations for existing customers.

         Direct operating expenses, excluding depreciation and amortization,
increased by $12.1 million or 542.3% to $14.3 million for the three month period
ended March 31, 2000 from $2.2 million for the three month period ended March
31, 1999. This increase is consistent with the acquisition and construction of
the 2,994 sites discussed above. Direct operating expenses as a percentage of
revenue increased to 35.9% for the three month period ended March 31, 2000 from
18.6% for the three month period ended March 31, 1999. The percentage increase
is primarily a result of the change in mix of sites. Both managed and leased
sites produce lower margins than owned sites because of their variable rent
expense. Notwithstanding, these sites are financially and strategically
consistent with our objective of providing wireless service providers a large
selection of antenna site locations.

         General and administrative expenses increased for the three month
period ended March 31, 2000 to $1.9 million from $0.8 million for the three
month period ended March 31, 1999. The increases in expenses are from additional
staffing required for the increased work volume, increased levels of advertising
and marketing expenditures, and other related costs associated with our growth.
However, as a percentage of revenue, it decreased to 4.8% of revenue for the
three month period ended March 31, 2000 from 7.0% for the three month period
ended March 31, 1999 reflecting the disproportionately higher growth in revenues
relative to expenses. The decrease in percentage is from economies of scale
realized from increases in revenues as a result of our acquisitions and
construction of communications sites.

         Corporate development expenses increased by $2.2 million or 126.2% to
$3.9 million for the three month period ended March 31, 2000 from $1.7 million
for the three month period ended March 31, 1999. Corporate development expenses
decreased as a percentage of revenue to 9.7% for the three month period ended
March 31, 2000 compared to 14.3% for the three month period ended March 31,
1999. The increase in expense is related to the overall growth in the business
and related activity during this same period. The decrease in percentage is from
economies of scale realized from increases in tower revenues relative to direct
operating expenses as a result of Pinnacle's acquisitions and construction of
communications sites.

                                       11
<PAGE>

         State franchise, excise and minimum taxes, which represent taxes
assessed in connection with our operations in various state jurisdictions,
increased to $0.4 million for the three month period ended March 31, 2000 from
$0.2 for the three month period ended March 31, 1999. Such taxes are calculated
using various methods such as a portion of our property within a given state,
our capital structure or based upon a minimum tax in lieu of income taxes. The
increase in expense is related to the overall growth in the business and related
activity during this same period.

         Interest expense, net of amortization of original issue discount,
increased 125.0% to $8.8 million for the three month period ended March 31, 2000
from $3.9 million for the three month period ended March 31, 1999. The increase
in interest expense was attributable to increased borrowing associated with our
acquisitions and construction activity during the period since March 31, 1999,
and that the weighted average balance of debt outstanding during the three month
period ended March 31, 1999 (approximately $160 million) was much lower than
that outstanding during the three month period ended March 31, 2000
(approximately $438 million) as a result of the use of proceeds from the
Offering in February 1999 to pay down our debt outstanding under our Senior
Credit Facility.

LIQUIDITY AND CAPITAL RESOURCES

         Our liquidity needs arise from our acquisition-related activities, debt
service obligations, working capital needs and capital expenditures. We have
historically funded our liquidity needs with proceeds from equity contributions,
public equity offerings, bank borrowings, debt offerings, and cash flow from
operations. We had net working capital of $188.6 million and $40.4 million as of
March 31, 2000 and December 31, 1999, respectively. Our ratio of total debt to
stockholders' equity was 1.2 to 1.0 at March 31, 2000 and 1.9 to 1.0 at December
31, 1999.

         Our Senior Credit Facility provides us with a $235 million revolving
line of credit, with an uncommitted increase option which could increase the
revolving line of credit to $435 million, a $125 million term loan and a $110
million term loan, for a total availability of up to $670 million, of which $520
million (including letters of credit) is currently committed. Under our
revolving line of credit, we may make borrowings and repayments until June 30,
2006. Under one term loan, advances must be repaid in full by June 30, 2006.
Under the other term loan, advances must be repaid in full by June 30, 2007.
Once repaid, amounts under the term loans may not be reborrowed. Advances under
the term loans may be used for refinancing certain existing indebtedness,
acquisitions, working capital, and other general corporate purposes. Advances
under our revolving line of credit are limited to acquisitions. Advances under
our Senior Credit Facility have been used primarily to fund acquisitions,
construction of new communications sites and improvements to existing
communications sites.

         Beginning September 30, 2001, the availability under our revolving line
of credit and one term loan starts reducing by specified amounts on a quarterly
basis until June 30, 2006, when the availability under such credits will be
reduced to zero. Beginning June 30, 2001, the availability under the other term
loan starts reducing by specified amounts on a quarterly basis until June 30,
2007, when the term loan must be repaid in full. As of March 31, 2000 we had
$195.4 million available under our Senior Credit Facility, after giving effect
to approximately $34.0 million of outstanding letters of credit, which reduced
availability under our Senior Credit Facility.

         We also use seller financing to fund certain of our communications site
acquisitions. As of March 31, 2000, we had outstanding, in the aggregate amount,
$35.8 million of seller notes bearing interest at rates ranging from 8.5% to
13.0% per annum.

         On February 19, 1999, we completed the Offering where we sold
20,000,000 shares of our common stock and on March 19, 1999, the over-allotment
options were exercised and an additional 2,026,000 shares were sold. The initial
price per share was $14, resulting in net proceeds of approximately $290 million
before deducting the costs of the Offering. The proceeds were used to acquire
communications sites.

         On July 27, 1999, we completed a secondary offering of common stock
(the "July Offering") whereby we sold 8,650,000 shares of our common stock. The
price per share was $25, resulting in net proceeds from the July Offering of
approximately $206 million. Certain stockholders of Pinnacle also sold 2,350,000
shares of common stock, the net proceeds of which are not available to us. The
proceeds from the July Offering were invested initially in short-term liquid
securities and were used in conjunction with Pinnacle's availability of senior
debt under our amended Senior Credit Facility to fund acquisitions, the
construction of new communications sites and improvements to existing
communications sites.

         On January 24, 2000, we completed another secondary offering of common
stock (the "January Offering") whereby we sold 7,200,000 shares of our common
stock. The price per share was $41, resulting in net proceeds from the January
Offering of approximately $283 million. Certain stockholders of Pinnacle also
sold 3,150,000 shares of common stock, the net proceeds of which are not
available to us. The proceeds from the January Offering were invested initially
in short-term liquid securities and will be used to reduce our debt or be used
with borrowings made under the Senior Credit Facility to fund acquisitions, the
construction of new communications sites and improvements to existing
communications sites (approximately $106 million used through March 31, 2000).
The total shares sold included a concurrent exercise of the underwriters'
over-allotment option whereby 1,350,000 shares were sold (including 450,000
shares sold by certain of our stockholders).

         On March 22, 2000 we completed a private placement of $200 million of
5.5% Convertible Subordinated Notes Due 2007 (the "Convertible Notes") to
certain institutional purchasers pursuant to the exemption from registration
provided by Section 4(2) of the Securities Act. We repaid outstanding
revolving debt under our Senior Credit Facility with the net proceeds of $193.5
million from this private placement. We will pay interest on the Convertible
Notes on March 15 and September 15 of each year, with the first interest payment
to be made September 15, 2000. The Convertible Notes will mature on September
15, 2007 unless previously redeemed or repurchased. The Convertible Notes are
convertible into Pinnacle's common stock at the option of the Convertible Note
holders at an initial price of $78.375 per share, which conversion price is
subject to adjustment under the terms of the Convertible Notes. We may redeem
the Convertible Notes on or after March 21, 2003. Pursuant to a Registration
Rights Agreement dated March 22, 2000, we must use reasonable best efforts to
file a registration statement on or before June 20, 2000, to cover resales of
the Convertible Notes and the shares of Common Stock issuable upon conversion
of the Convertible Notes.

         Capital investments, including acquisitions, for the three month period
ended March 31, 2000 were $176.2 million, compared to $85.7 million in the
comparable 1999 period. Depending on availability of additional capital, we
expect that we may make substantial additional capital investments for
acquisitions, construction and upgrading of additional towers in 2000. We
currently estimate that we will make additional capital investments in 2000 of
at least $400 million. To the extent we commit to complete additional
significant acquisitions beyond those we have identified and currently believe
are probable that we will complete, that amount may increase materially.

         We believe that the availability under our Senior Credit Facility, cash
flow from operations and existing cash balances will be sufficient to meet
working capital requirements for existing properties and to fund our current
probable acquisitions. To the extent that we pursue additional acquisitions,
construction activity and other capital expenditures requiring funding in excess
of that then available under our Senior Credit Facility, we will be required to
obtain additional financing. To the extent that we are unable to finance future
capital expenditures, we may not be able to achieve our current business
strategy.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         We are exposed to certain market risks inherent in our financial
instruments. These instruments arise from transactions entered into in the
normal course of business and, in some cases, relate to our acquisitions of
related businesses. We are subject to interest rate risk on our Senior Credit
Facility and any future financing requirements. Our fixed rate debt consists
primarily of outstanding balances on the Notes, the Convertible Notes, and notes
payable to former tower owners and our variable rate debt relates to borrowings
under our Senior Credit Facility. See "--Liquidity and Capital Resources."

         The following table presents the future principal payment obligations
and weighted-average interest rates associated with our existing long-term debt
instruments assuming our actual level of long-term indebtedness of $325,000,000
under the Notes, $200,000,000 under the Convertible Notes, and $290,886,800
under our Senior Credit Facility as of March 31, 2000:

         Our primary market risk exposure relates to the following:

         o    the interest rate risk on long-term and short-term borrowings;

         o    our ability to refinance the Notes and the Convertible Notes at
              maturity at market rates;

         o    the impact of interest rate movements on our ability to meet
              interest expense requirements and exceed financial covenants; and

         o    the impact of interest rate movements on our ability to obtain
              adequate financing to fund future acquisitions.

         We manage interest rate risk on our outstanding long-term and
short-term debt through our use of fixed and variable rate debt. While we cannot
predict or manage our ability to refinance existing debt or the impact interest
rate movements will have on our existing debt, we continue to evaluate our
financial position on an ongoing basis.

INFLATION

         Because of the relatively low levels of inflation experienced in 1999
and 2000, inflation did not have a significant effect on our results in such
years.

PART II. OTHER INFORMATION

ITEM 1.       LEGAL PROCEEDINGS.

         We are from time to time involved in ordinary litigation incidental to
the conduct of our business. We believe that none of our pending litigation will
have a material adverse effect on our business, financial condition or results
of operations.

ITEM 2.       CHANGES IN SECURITIES AND USE OF PROCEEDS.

              On March 22, 2000, we completed a private placement of $200
million principal amount of 5.5% Convertible Subordinated Notes due 2007 to
certain institutional purchasers pursuant to the exemption from registration
provided by section 4(2) of the Securities Act. The 5.5% Notes are convertible
into shares of Common stock at the option of the holder at a conversion price of
$78.375 per share. The net proceeds to Pinnacle from such sale were
approximately $193.5 million (after deduction of the initial purchaser's
discount and estimated offering expenses). We used the net proceeds to repay
outstanding debt under our Senior Credit Facility. Pursuant to a Registration
Rights Agreement dated March 22, 2000, we must use reasonable best efforts to
file a registration statement on or before June 20, 2000, to cover resales of
the Convertible Notes and the shares of Common Stock issuable upon conversion
of the Convertible Notes.

ITEM 3.       DEFAULTS UPON SENIOR SECURITIES.

         Not applicable.

ITEM 4        SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
              ---------------------------------------------------

         Not applicable.

ITEM 5.       OTHER INFORMATION.

         We are taxed as a Real Estate Investment Trust ("REIT") for federal
income tax purposes. The federal tax laws and regulations relating to REITs
limit our ability to own and derive income from certain types of assets. In
order to minimize the risk that our ownership of or income from certain assets
might negatively affect our qualification as a REIT, we previously transferred
certain potentially non-REIT qualifying assets to PT III, a corporation in which
Pinnacle owns substantially all of the equity interests in the form of
nonvoting, convertible preferred stock, as well as approximately 9% of the
voting common stock. Certain officers of Pinnacle own the remaining outstanding
shares of voting common stock of PT III. During the first quarter ended March
31, 2000, Pinnacle purchased approximately $2.4 million of additional
convertible preferred stock of PT III and approximately $9.5 million of
additional convertible promissory notes. PT III used such funds to acquire all
of the stock of a corporation that owns and manages communications sites,
certain of which may not be REIT qualifying assets or generate income from
assets that are non-REIT qualifying, and to acquire certain assets used in
communication tower consulting and management activities, which assets and the
income generated thereby may not be REIT qualifying.

         PT III has guaranteed the Senior Credit Facility and has pledged all of
its assets to secure such guarantee. The Board of Directors of Pinnacle,
excluding the officers of Pinnacle owning PT III common stock, who abstained,
approved the transactions with PT III and determined that such transactions were
on terms no less favorable to Pinnacle than those that would be obtained in
comparable arms-length transactions with parties that were not affiliated with
Pinnacle, and that such transactions were in the best interests of Pinnacle.

         As a result of the acts referenced in the preceding paragraph and prior
transactions between PT III and a subsidiary of Pinnacle, a subsidiary of
Pinnacle currently owns $ 48.7 of convertible promissory notes issued by PT III
that accrues interest at the rate of 13%, with interest payable quarterly and
all principal and accrued interest due and payable within 30 days upon demand,
and $12.2 million of PT III convertible preferred stock that accrues dividends
at 18% per annum, payable quarterly. The terms of PT III's certificate of
incorporation limit PT III's ability to borrow money, pledge its assets, issue
additional securities, make distributions to its stockholders, purchase and sell
assets, enter into transactions with


                                       15
<PAGE>

affiliates and take certain actions without seeking approval from its common
stockholders, and its ability to issue or redeem certain securities, make
certain distributions, enter into certain transactions with its affiliates or to
sell, lease or dispose of a majority of its assets without the approval of the
holders of the convertible preferred stock is also limited by such certificate
of incorporation. Should all of the PT III convertible preferred stock and the
convertible promissory notes be fully converted to common stock of PT III, a
subsidiary of Pinnacle would own in excess of 99.9% of the outstanding common
stock of PT III. We currently anticipate that the officers of Pinnacle who own
PT III common stock will derive only such benefits as are consistent with, and
not greater than, the very small interest in the overall equity of Pinnacle
represented by their common stock and as such that such officers will not
receive significant benefits from such stock ownership. PT III may issue limited
amounts of nonvoting common stock in the future in order for it to independently
qualify as a REIT.

         The foregoing is merely a summary description of PT III and the
transactions between it and Pinnacle. The description does not purport to be a
complete description of such matters and is subject to the provisions of, and is
qualified in its entirety be reference to, the material agreements relating to
those matters, copies of which are filed as exhibits to this Quarterly Report on
Form 10-Q.

         We continue to assess the risk to our status as a REIT that might
result from us reacquiring the assets transferred to PT III. Depending upon the
conclusions reached from such assessment, we may seek to reacquire such assets
by purchase, merger or other means. It is possible that we may enter into
additional transactions with PT III or other similar entities in certain
circumstances to minimize the risk that we may no longer qualifying as a REIT.
In addition, as additional acquisition opportunities become available to us in
our existing line of business or in complimentary non-real estate based
communication site or services activities, we may determine that it is in our
best interests to acquire, operate or derive income from assets, businesses or
entities that would cause us to no longer qualify as a REIT.

ITEM 6.       EXHIBITS AND REPORTS ON FORM 8-K.

         (a) The Exhibits listed in the "Exhibit Index" are filed as part of
this report.

         (b) Reports on Form 8-K. Pinnacle filed a report on Form 8-K on January
4, 2000 regarding its acquisition of 201 communications sites on March 4, 1998
from Southern Communications Services, Inc. ("Southern Communications"), a
subsidiary of Southern Company. We paid $83.5 million for these communications
sites located in Georgia, Alabama, Mississippi and Florida.
