              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 30, 1998
                                  (UNAUDITED)

1.     THE COMPANY

       Preferred Networks, Inc. ("PNI"), headquartered in metropolitan Atlanta,
       provides outsourcing solutions to the wireless industry which allow
       companies to offer branded wireless services directly to subscribers,
       while relying on PNI to provide high-quality network, technical, and
       product services. PNI offers its services through its Network Services
       Division, a provider of wholesale paging network service as one of the
       largest carrier's carriers in the U.S., and through its wholly-owned
       subsidiaries: Preferred Technical Services, Inc. ("PTS"), a provider of
       paging network equipment installation, maintenance and engineering
       services; and EPS Wireless, Inc. ("EPS"), a national provider of paging
       and cellular product repair services, sales of new, used and refurbished
       paging and cellular products and inventory management services.

       The Company has formed wholly-owned subsidiaries and limited liability
       companies to execute certain business transactions. All significant
       intercompany activity has been eliminated.

2.     BASIS FOR PRESENTATION

       The interim condensed consolidated financial information contained
       herein has been prepared by the Company, without audit, pursuant to the
       rules and regulations of the Securities and Exchange Commission ("SEC")
       and include in the opinion of management, all adjustments, which are of
       a normal recurring nature necessary for a fair presentation of the
       financial position, results of operations and cash flows for the periods
       presented. Certain information and footnote disclosures normally
       included in financial statements prepared in accordance with generally
       accepted accounting principles ("GAAP") have been condensed or omitted
       pursuant to such rules and regulations. The Company believes, however,
       that its disclosures are adequate to make the information presented not
       misleading. These financial statements and related notes should be read
       in conjunction with the financial statements and notes as of December
       31, 1997, included in the Company's Annual Report on Form 10-K (File No.
       0-27658). Results of operations for the periods presented herein are not
       necessarily indicative of results to be expected for the full year or
       any other interim period.

3.     SUPPLEMENTAL CASH FLOW INFORMATION

       Cash and cash equivalents include investments in money market
       instruments, which are carried at fair market value. Cash payments made
       for interest during the six months ended June 30, 1998 and 1997 were
       approximately $622,000 and $575,000, respectively. There were no
       significant federal or state income taxes paid or refunded for the six
       months ended June 30, 1998 and 1997.

4.     LOSS PER SHARE

       Net loss per share was computed and restated, in the case of periods
       prior to the fourth quarter of 1997, using the requirements of Statement
       of Financial Accounting Standards No. 128, Earnings per Share, and Staff
       Accounting Bulletin No. 98. Net loss per share-basic was computed by
       dividing net loss attributable to common stock by the weighted average
       number of shares of common stock outstanding during the period excluding
       unvested shares of restricted stock. The denominator for net loss per
       share-diluted also considers the dilutive effect of outstanding stock
       options, warrants, and convertible preferred stock. Due to the Company's
       net loss, the amounts reported for basic and diluted are the same. The
       following securities could potentially dilute basic earnings per share
       in the future and were not included in the computation of diluted net
       loss per share because they would have been antidilutive for the period
       presented:

5.     ACQUISITIONS

       In January 1997, the Company acquired the stock of Mercury Paging &
       Communications, Inc. ("Mercury") and its affiliated companies for
       approximately $14.2 million of which approximately $10.0 million was
       paid in cash and the remainder by the issuance of 624,321 shares of
       Common Stock. Proceeds from the Comprevolving credit facility which were
       drawn in December 1996 were used to fund the majority of the cash
       portion of the purchase price, with working capital being used to fund
       the remainder. The transaction was accounted for as a purchase as of
       January 31, 1997. Mercury is a reseller-based paging carrier in the
       states of New York, New Jersey, and Connecticut. Prior to closing, the
       Company earned revenues from Mercury under an agency agreement.

6.     ISSUANCE OF CLASS B SENIOR REDEEMABLE PREFERRED STOCK AND COMMON STOCK 
       PURCHASE WARRANTS

       In March 1998, the Company issued 5,333,336 shares of Class B Senior
       Redeemable Preferred Stock (the "Class B Preferred") and warrants to
       purchase up to 5.4 million shares of Common Stock for a total purchase
       price of $8 million. Dividends accrue at the rate of 15% per annum, are
       cumulative and compound annually. The Class B Preferred may be redeemed
       at any time at the option of the Company at a price equal to $1.50 per
       share plus accrued dividends and if the holder so demands, five years
       from the date of issuance, the Class B Preferred must be redeemed by the
       Company at a price equal to $1.50 per share plus accrued dividends. In
       the event of redemption of the Company's Class A Redeemable Preferred
       Stock (the "Class A Preferred"), the Company must simultaneously redeem
       the Class B Preferred. Each warrant is exercisable for five years
       following the issuance of the Class B Preferred and entitles the holder
       to purchase one share of Common Stock for $1.50 per share subject to
       possible downward adjustment based on any private placement of the
       Company's Preferred or Common Stock for less than $1.50 per share. The
       Class B Preferred is recorded at cost, net of expenses, plus accretion
       and undeclared dividends.

7.     IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

       In June 1997, the Financial Accounting Standards Board issued Statement
       No. 131 "Disclosures about Segments of an Enterprise and Related
       Information" ("FAS 131"), which establishes standards for the way public
       business enterprises report information about operating segments in
       their financial statements. FAS 131 also establishes standards for
       related disclosures about products and services, geographic areas, and
       major customers. FAS 131 is effective for annual financial statements
       for periods beginning after December 15, 1997. The Company will adopt
       FAS 131 in 1998 and does not expect the effect of adoption to be
       material to its consolidated financial statements but additional
       disclosures may be required.

       In April 1998, the Accounting Standards Executive Committee (AcSEC)
       issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
       Activities" ("SOP 98-5"). SOP 98-5 requires entities to charge to
       expense start-up costs, including organizational costs, as incurred. In
       addition, SOP 98-5 requires a write-off of any previously capitalized
       start-up or organization costs, and must be reported as the cumulative
       effect of a change in accounting principle. SOP 98-5 is effective
       January 1, 1999. The Company will adopt SOP 98-5 by the required date
       and will write off the unamortized balance of its market entry costs and
       cease to capitalize such costs at that time. Market entry costs net of
       accumulated amortization at June 30, 1998 were approximately $1.9
       million. Additional amounts capitalized, net of amortization expense,
       during the three months ended June 30, 1998 and 1997 were ($20,000) and
       $226,000, respectively, and during the six months ended June 30, 1998
       and 1997 were ($117,000) and $451,000, respectively.

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

OVERVIEW

In this section, the Company makes reference to "EBITDA" which represents
earnings before interest expense, interest income, taxes, depreciation and
amortization. EBITDA is a financial measure commonly used in the
telecommunications industry and should not be construed as an alternative to
operating income (as determined in accordance with generally accepted
accounting principles ("GAAP")), as an alternative to cash flows from operating
activities (as determined in accordance with GAAP), or as a measure of
liquidity.

The table below provides the components of the Company's consolidated
statements of operations and EBITDA for each of the three months and the six
months ended June 30, 1998 and 1997, respectively, as a percentage of total
revenues.

RESULTS OF OPERATIONS

Total revenues increased by $274,000, or 2.9%, to $9.9 million for the three
months ended June 30, 1998 from $9.6 million for the three months ended June 30,
1997. Total revenues increased by $1.8 million, or 10.3%, to $19.5 million for
the six months ended June 30, 1998 from $17.7 million for the six months ended
June 30, 1997.

Revenues from network services increased by $44,000, or 1.4%, to $3.3 million
for the three months June 30, 1998 from $3.3 million for the three months ended
June 30, 1997. Revenues from network services increased by $742,000, or 12.7%,
to $6.6 million for the six months ended June 30, 1998 from $5.8 million for the
six months ended June 30, 1997. The Company has experienced an increase in
network services revenue as unit growth and the associated recurring revenue
stream have continued both in existing markets and in new markets as well as
from the acquisition of Mercury Paging & Communications, Inc., ("Mercury"), a
reseller-based paging carrier acquired in January 1997. The Company expanded to
27 markets at June 30, 1998 from 23 markets at June 30, 1997. Units in service
increased by 76,525, or 18.0%, to 501,516 from 424,991 over the prior year three
month period. Airtime revenue per unit decreased by $0.37 for the three months
ended June 30, 1998 compared to the three months ended June 30, 1997. Airtime
revenue per unit decreased by $0.23 for the six months ended June 30, 1998
compared to the six months ended June 30, 1997. This decrease is primarily due
to an increase in units in service from colocation/interconnection customers as
a percentage of total units in service. The Company incurs minimal marginal cost
in supplying only airtime to its colocation/interconnection customers and
therefore charges these customers substantially less per unit in service per
month than it charges its reseller customers.

Revenues from product sales increased by $148,000, or 4.3%, to $3.6 million for
the three months June 30, 1998 from $3.5 million for the three months ended
June 30, 1997. Revenues from product sales increased by $1.1 million, or 17.3%,
to $7.5 million for the six months ended June 30, 1998 from $6.4 million for
the six months ended June 30, 1997. The increase in revenues from product sales
resulted from growth during 1998 of sales of new, used and refurbished pager
and cellular products.

Other services revenues increased by $82,000, or 2.9%, to $2.9 million for the
three months ended June 30, 1998 from $2.9 million for the three months ended
June 30, 1997. Other services revenues decreased by $29,000 or 0.1%, to $5.5
million for the six months ended June 30, 1998. The decrease for the six months
ended June 30, 1998 is primarily due to decreased revenue charged per unit for
pager repair and refurbishment services, at EPS, which the Company believes will
be offset in the future by higher volumes of units serviced. This decrease is
offset in the second quarter of 1998 by increases in technical services revenue
at PTS.

Cost of network services decreased by $9,000, or 0.4%, to $2.2 million for the
three months ended June 30, 1998 from $2.2 million for the three months ended
June 30, 1997, and decreased as a percentage of network services revenue to
66.3% for the three months ended June 30, 1998 from 67.5% for the three months
ended June 30, 1997. Cost of network services increased by $237,000, or 5.8%,
to $4.3 million for the six months ended June 30, 1998, but decreased as a
percentage of network services revenue to 66.2% for the six months ended June
30, 1998 from 70.6% for the six months ended June 30, 1997. As markets generate
increased revenue, the decrease in costs as a percentage of revenue is expected
due to the fixed nature of many of these expenses.

Cost of product sales decreased by $454,000, or 12.8%, to $3.1 million for the
three months ended June 30, 1998 from $3.6 million for the three months ended
June 30, 1997. Cost of product sales decreased by $302,000, or 4.5%, to $6.3
million for the six months ended June 30, 1998 from $6.6 million for the six
months ended June 30, 1997. Cost of product sales as a percentage of product
sales decreased to 85.7% for the three months ended June 30, 1998 from 102.5%
for the three months ended June 30, 1997. Cost of product sales decreased
primarily due to EPS's profitable product sales, and to a lesser extent due to
decreasing losses on pagers sold to its network customers. The Company also
reduced the carrying cost of its inventory by $186,000 as of June 30, 1998 to
the lower of cost or market compared to a $612,000 writedown as of June 30,
1997.

Cost of other services decreased by $105,000, or 4.4% to $2.3 million for the
three months ended June 30, 1998 from $2.4 million for the three months ended
June 30, 1997. Cost of other services decreased by $166,000, or 3.8%, to $4.2
million for the six months ended June 30, 1998 from $4.4 million for the six
months ended June 30, 1997. The decrease in cost of other services is primarily
due to the decrease in pager repair and refurbishment services revenue offset in
part by increases in costs associated with increased technical services
revenues.

Selling, general and administrative expenses (SG&A) decreased by $912,000, or
20.7%, to $3.5 million for the three months ended June 30, 1998 from $4.1
million for the three months ended June 30, 1997. SG&A decreased as a
percentage of total revenues to 35.4% for the three months ended June 30, 1998
from 43.0% for the three months ended June 30 1998. SG&A expenses decreased to
$7.1 million for 

                                       9

the six months ended June 30, 1998 from $8.5 million for the six months ended
June 30, 1997. The decrease in SG&A expenses is primarily due to certain
non-recurring severance expenses incurred in the second quarter of 1997 related
to personnel cost reduction measures. SG&A decreased as a percentage of total
revenues to 36.4% for the six months ended June 30, 1998, from 48.0% for the six
months ended June 30, 1997. The decrease in SG&A expenses is primarily due to
personnel cost reduction measures taken in the second quarter of 1997. In
addition, because the Company does not market directly to end-users, it does
not incur subscriber-related acquisition costs and, accordingly, its SG&A
expenses do not increase in direct proportion to its revenue growth.

Depreciation and amortization decreased by $172,000, or 9.5%, to $1.6 million
for the three months ended June 30, 1998 from $1.8 million for the three months
ended June 30, 1997. Depreciation and amortization decreased as a percentage of
total revenues to 16.5% for the three months ended June 30, 1998 from 18.8% for
the three months ended June 30, 1997. Depreciation and amortization decreased by
$58,000 or 1.7%, to $3.4 million for the six months ended June 30, 1998 from
$3.4 million for the six months ended June 30, 1997. Depreciation and
amortization decreased as a percentage of total revenues to 17.4% for the six
months ended June 30, 1998 from 19.5% for the six months ended June 30, 1977.
Depreciation and amortization decreased primarily due to less amortization
expense incurred in the current year as market start-up costs become fully
amortized offset in part by increased depreciation expense on additional assets
placed in service in 1998.

Other expenses decreased by $278,000, or 100.0% to $0 for the three and six
months ended June 30, 1998. The decrease is due to certain non-recurring
severance expenses incurred in the second quarter of 1997 related to personnel
cost reduction measures.

Interest expense, net of capitalized amounts, decreased by $85,000, or 22.4%,
to $294,000 for the three months ended June 30, 1998 from $380,000 for the
three months ended June 30, 1997. Interest expense increased $15,000, or 2.4%,
to $621,000 for the six months ended June 30, 1998, from $606,000 for the six
months ended June 30, 1997 due to the financing of the network buildout and
borrowings related to the January 1997 acquisition of Mercury.

Interest income increased by $47,000 or 59.0% to $126,000 for the three months
ended June 30, 1998 from $79,000 for the three months ended June 30, 1997.
Interest income decreased $17,000, or 8.0%, to $200,000 for the six months
ended June, 30, 1998 from $218,000 for the six months ended June 30, 1997.

Net loss for the three months ended June 30, 1998 as compared to the three
months ended June 30, 1997 decreased to $3.0 million from $5.0 million. Net
loss for the six months ended June 30, 1998, as compared with the six months
ended June 30, 1997 decreased to $6.3 million from $9.8 million due to
substantial increases in gross margin combined with decreases in SG&A, as
described above. The net loss attributable to Common Stock decreased due to the
lower net loss, offset in part by higher accretion and dividends related to the
Class A Redeemable Preferred Stock ("the Class A Preferred") and the Class B
Senior Redeemable Preferred Stock ("the Class B Preferred"), issued in June
1997 and March 1998, respectively.

The net loss per share of Common Stock for the three months ended June 30, 1998
decreased to $0.23 from $0.32 for the three months ended June 30, 1997. The net
loss per share of Common Stock for the six months ended June 30, 1998 decreased
to $0.47 from $0.62 for the same six months ended in 1997, due to the Company's
decreased net loss, which was offset in part by higher accretion and dividends
on the Company's outstanding preferred stock. All prior year net loss per share
amounts have been restated to conform to Statement of Financial Accounting
Standards No. 128 and Staff Accounting Bulletin No. 98.

LIQUIDITY AND CAPITAL RESOURCES

The Company's expansion strategy has historically required substantial funds to
finance the expansion of existing operations, the expansion into new markets as
part of the nationwide build-out of its networks, the purchase of network
assets and related FCC licenses, capital expenditures, debt service and general
corporate purposes. Because the Company's network expansion is in its later
stages, the Company expects that its capital expenditures in 1998 will be
reduced compared to 1997. The timing and construction of additional markets
will depend, among other things, on customer requirements and the timing and
availability of capital.

 The Company's net cash used in operations was $4.5 million and $7.2 million for
the six months ended June 30, 1998 and 1997, respectively. The primary reasons
for the reduction in net cash used in operations were the decrease in the net
loss from operations and a decrease in accounts receivable compared to the prior
year period.

 Capital expenditures were $852,000 and $3.7 million for the six months ended
June 30, 1998 and 1997, respectively, reflecting the later stage of the
Company's network expansion. The Company has funded its expansion in the past by
equity infusions, bank and finance company debt, loans from stockholders, and
vendor and seller financing.

 In 1997 and prior years, the Company expanded and augmented its local and
wide-area 157.740 MHz networks by purchasing and consolidating existing local
network assets licensed on the 150 MHz, 450 MHz and 900 MHz

frequency bands to offer additional capacity and flexibility to its customers.

In June 1997, the Company sold $15 million of Class A Preferred with warrants
to certain existing stockholders. The Class A Preferred accrues cumulative
dividends at a rate of 10.0% of its original principal value per annum. The
holders of the Class A Preferred were issued warrants to purchase 11.5 million
shares of Common Stock at an exercise price of $1.50 per share. No dividends on
the Class A Preferred have been paid as of June 30, 1998.

 In March 1998, the Company sold $8.0 million of Class B Preferred with
warrants to one institutional investor and certain of its existing
stockholders. The Class B Preferred accrues cumulative dividends at a rate of
15.0% of its liquidation value, compounded annually. The holders of the Class B
Preferred were issued warrants to purchase 5.4 million shares of Common Stock
at an exercise price of $1.50 per share. No dividends on the Class B Preferred
have been paid as of June 30, 1998.

The Company has a secured credit facility for $12.0 million of vendor financing
bearing interest at the five-year U.S. Treasury rate plus 6.5% payable in
various monthly installments of principal and interest over 60 months. This
credit facility contains various conditions, financial covenants and
restrictions and is secured by paging equipment. As of June 30, 1998, there was
$5.5 million outstanding under this facility with $5.7 million available.

 The Company has a secured credit facility for $5.0 million to finance paging
system equipment from a finance company bearing interest between 10% and 11%
payable in various monthly installments of principal and interest over 60
months. This credit facility contains various conditions, financial covenants
and restrictions and is secured by paging equipment. As of June 30, 1998, there
was $3.4 million outstanding under this facility with no additional
availability.

The Company has a $11.0 million credit facility with a financial institution,
which is to be used to finance paging network acquisitions and for general
working capital purposes. The outstanding balance under this facility bears
interest at either (i) 1% plus the higher of the Federal Funds Rate for each
day plus 1/2% or prime, or (ii) LIBOR plus 3.75%, at the Company's option.
Borrowings under this facility are secured by substantially all the assets of
the Company. This credit facility contains various conditions and financial
covenants, including but not limited to a requirement to maintain a minimum
cash balance of $4 million at all times. The amount outstanding under this
facility as of June 30, 1998 was $10.0 million, with $118,000 in additional
availability.

 At June 30, 1998, the Company had $7.6 million invested in short-term
investment grade securities at various interest rates.

 Management believes that cash and cash equivalents on hand together with the
secured credit facilities described above, will be sufficient to meet the
Company's working capital, capital expenditure and debt covenant requirements
to the end of the second quarter of 1999 without requiring additional vendor or
other financing. The Company may need additional funds in the form of equity,
bank debt or other debt financing in the future to execute its business plan.
However, no assurances can be given that if additional funds are required, such
funds will be available on terms acceptable to the Company, if at all, and the
failure to obtain such funds could have a material adverse effect on the
Company.

ACQUISITIONS

In January 1997, the Company acquired the stock of Mercury and its affiliated
companies for a total purchase price of $14.2 million. The transaction was
accounted for as a purchase as of January 31, 1997. Of this amount, the Company
paid $10.0 million in cash and issued 624,321 shares of Common Stock. Mercury
was a reseller-based paging carrier in the states of New York, New Jersey and
Connecticut. Prior to closing, the Company earned revenues from Mercury under
an agency agreement.

YEAR 2000 COMPUTER ISSUE

 Many computer systems in use today were designed and developed using two
digits, rather than four, to specify the year. As a result, such systems will
recognize the year 2000 as "00." This may cause many computer applications to
fail completely or to create erroneous results unless corrective measures are
taken.

 The Company utilizes software and related computer technologies essential to
its operations that will be affected by the Year 2000 issue. Although the
Company's evaluation is continuing, the Company currently believes that most of
its software is already Year 2000 compliant and the cost, if any, of modifying
its remaining software will not be material, or require extensive time.
