1. GENERAL

     PageMart, Inc. ("PageMart") was incorporated as a Delaware corporation on
May 8, 1989 to provide wireless messaging products and services. In January
1995, PageMart effected a corporate reorganization pursuant to which PageMart
Nationwide, Inc., a Delaware corporation, became the holding company parent of
PageMart. In December 1995, the corporate name was changed from PageMart
Nationwide, Inc. to PageMart Wireless, Inc. ("Wireless"). Wireless and its
subsidiaries are referred to herein as the "Company." The consolidated
financial statements of the Company include the accounts of PageMart and
PageMart PCS, Inc., a wholly owned subsidiary of Wireless, ("PageMart PCS").
PageMart PCS holds certain narrowband personal communications services
licenses. The consolidated financial statements of PageMart include the
accounts of PageMart II, Inc., PageMart Operations, Inc., PageMart of
California, Inc., PageMart of Virginia, Inc. and PageMart International, Inc.
Each of these companies is a wholly-owned subsidiary of PageMart. PageMart II,
Inc. and PageMart Operations, Inc. hold certain Federal Communications
Commission ("FCC") licenses. PageMart International, Inc., which has had no
significant operations to date, holds certain investments in an international
venture in Canada. Other than these licenses and international investments, the
subsidiaries of PageMart have no significant assets or liabilities.

2. BASIS OF PRESENTATION

     The accompanying unaudited condensed consolidated financial statements
have been prepared by the Company in accordance with generally accepted
accounting principles for interim financial information and are in the form
prescribed by the Securities and Exchange Commission in instructions to Form
10-Q and Article 10 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. The interim unaudited financial
statements should be read in conjunction with the audited financial statements
of the Company for the year ended December 31, 1996. In the opinion of
management, all adjustments (consisting only of normal recurring accruals)
considered necessary for a fair presentation have been included. Operating
results for the three and six months ended June 30, 1997 are not necessarily
indicative of the results that may be expected for the year ending December 31,
1997.

     Certain amounts in the prior year condensed consolidated financial
statements have been reclassified to conform with the current year
presentation.

3. NET LOSS PER SHARE

     Net loss per share amounts as reflected on the statements of operations
are based upon the weighted average number of common shares outstanding. As
required by the Securities and Exchange Commission rules, all warrants, options
and shares issued during the year immediately preceding the June 1996 initial
public offering are assumed to be outstanding for all periods presented.

     The Company will adopt the provisions of Statement of Financial Accounting
Standards No. 128, "Earnings per Share," ("SFAS No. 128") in the fourth quarter
of fiscal 1997. SFAS No. 128, issued February 1997, replaces the primary
earnings per share calculation with a basic earnings per share calculation and
modifies the calculation of diluted earnings per share. The Company anticipates
the adoption of SFAS No. 128 will have no impact on its reporting of net loss
per share for 1997 or prior periods.

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

     The following is a discussion of the results of operations and financial
condition of the Company for the three and six months ended June 30, 1997 and
1996. This discussion should be read in conjunction with the Company's
condensed consolidated financial statements and the notes thereto included
elsewhere in this report.

     When used in this discussion, the words `estimate,' `project,' `plan,'
`expect' and similar expressions are intended to identify forward-looking
statements. Such statements are subject to certain risks and uncertainties that
could cause actual results to differ materially from those projected. Readers
are cautioned not to place undue reliance on these forward-looking statements,
which reflect management's judgment only as of the date hereof.

GENERAL

     The Company has constructed and operates a wireless messaging and
communications network and provides paging and other one-way wireless messaging
services to its subscribers. In addition, the Company sells and distributes
wireless messaging equipment to subscribers, retailers and resellers. The
Company earns recurring revenues from each subscriber in the form of fixed
periodic fees and incurs substantial operating expenses in offering its
services, including technical, customer service and general and administrative
expenses. See "Management's Presentation of Results of Operations."

     Since commencing operations in 1990, the Company has invested heavily in
its one-way wireless communications network and administrative infrastructure
in order to establish nationwide coverage, sales offices in major metropolitan
areas, customer service call centers and centralized administrative support
functions. The Company incurs substantial fixed operating costs related to its
one-way wireless communications infrastructure, which is designed to serve a
much larger subscriber base than the Company currently serves in order to
accommodate growth. In addition, the Company incurs substantial costs
associated with new subscriber additions. As a result, the Company has
generated significant net operating losses for each year of its operations. See
"Management's Presentation of Results of Operations."

     The Company's strategy is to expand its subscriber base and to increase
profitability and cash flow through greater utilization of its nationwide
wireless communications network. From June 30, 1996 to June 30, 1997, the
number of domestic units in service increased from 1,524,297 to 2,181,775. None
of the Company's growth is attributable to acquisitions. Given its growth
strategy and the substantial associated selling and marketing expenses, the
Company expects to continue to generate operating losses in 1997 from its
one-way wireless communications business. In addition, the Company began
testing and development of two-way wireless messaging services in 1996 and
plans to continue the development and implementation in 1997 and 1998. The
Company expects to incur additional operating losses during the start-up phase
for two-way wireless messaging services. The Company does not anticipate any
significant revenues from two-way services during 1997, however, it expects to
generate revenues with respect to two-way services in 1998. The Company's
ability to generate operating income is primarily dependent on its ability to
attain a sufficiently large installed subscriber base that generates recurring
revenues which offsets the fixed operating costs of its wireless networks,
administration and selling and marketing expenses. The Company intends to
achieve this growth by promoting its customized paging and other wireless
messaging services through its national sales offices, retail distribution
channels, private brand strategic alliances with GTE Corporation, Southwestern
Bell Mobile Systems, AT&T Wireless Services, Ameritech Mobile Services, Inc.
and long distance reseller EXCEL Communications, Inc., and international
expansion.

     Unlike most other paging carriers, the Company sells, rather than leases,
substantially all of the messaging equipment used by its subscribers. As a
result, the Company has much less capital invested in messaging equipment than
other paging carriers since it recoups a substantial portion of messaging
equipment costs upon sale to retailers and subscribers. This results in
significantly lower capital expenditures and depreciation expense than if the
Company leased such equipment to its subscribers. In addition, the Company's
financial results are much different from those of other paging carriers that
lease messaging equipment to subscribers because the Company recognizes the
cost of messaging equipment sold in connection with adding new subscribers at
the time of sale rather than




                                       7
<PAGE>   8


capitalizing and depreciating the cost of messaging equipment over periods
ranging from three to five years as occurs with paging carriers that lease
messaging equipment to subscribers. In addition, the Company's retail
distribution strategy results in the recognition of expenses associated with
messaging equipment sales and other sales and marketing expenses in advance of
new subscribers being added to the base and generating revenues (as retailers
carry inventory).

     The Company sells its messaging equipment through multiple distribution
channels, including direct sales, third-party resellers, private brand
strategic alliances and local and national retail stores. Selling and marketing
expenses are primarily attributable to compensation paid to the Company's sales
force, advertising and marketing costs and to losses resulting from the fact
that, for competitive and marketing reasons, the Company generally sells each
new unit for less than its acquisition cost. The Company's accounting practices
result in selling and marketing expenses, including loss on sale of equipment,
being recorded at the time a unit is sold. Units sold by the Company during a
given month may exceed units activated and in service due to inventory stocking
by and distribution strategies of national retailers. As a result, selling and
marketing expenses per net subscriber addition may fluctuate from period to
period.

     The Company derives its recurring revenue primarily from fixed periodic
fees for services that are not generally dependent on usage. Consequently, the
Company's ability to recoup its initial selling and marketing costs, to meet
operating expenses and to achieve profitability is dependent on the average
length of each customer's subscription period. As long as a subscriber
continues to utilize the Company's service, operating results benefit from the
recurring payments of the fixed fees without the incurrence of additional
selling expenses by the Company. Conversely, operating results are adversely
affected by customer disconnections. Each month a percentage of the Company's
existing customers have their service terminated for a variety of reasons,
including failure to pay, dissatisfaction with service and switching to a
competing service provider. The Company's average monthly disconnection rates
for the years ended December 31, 1994, 1995 and 1996 and the six months ended
June 30, 1997 were 3.4%, 2.5%, 2.4% and 2.4%, respectively.

     Approximately 90% of the Company's average monthly revenue per unit
("ARPU") is attributable to fixed fees for airtime, coverage options and
features. A portion of the remainder of additional ARPU is dependent on usage.

RESULTS OF OPERATIONS

     The Company's principal operations to date are its domestic one-way
wireless messaging division. The following discussion of results of operations
analyzes the results of the Company's one-way wireless messaging operations,
unless otherwise indicated.

     Certain of the following financial information is presented on a per unit
basis. Management believes that such a presentation is useful in understanding
the Company's results because it is a meaningful comparison period to period
given the Company's growth rate and the significant differences in the number
of subscribers of other paging companies.

THREE AND SIX MONTHS ENDED JUNE 30, 1996 AND 1997

Units in Service

     Units in service from domestic operations were 1,524,297 and 2,181,775 as
of June 30, 1996 and 1997, respectively, representing an annual growth rate of
43%. In addition, for the three and six months ended June 30, 1997, PageMart
Canada Limited ("PageMart Canada") added 5,629 and 11,721 subscribers,
respectively. As a result of its ownership interest in PageMart Canada, the
Company's proportional share of net subscriber additions from PageMart Canada
was 3,378 and 7,033 units for the three and six months ended June 30, 1997,
respectively. The Company has experienced strong growth in units in service due
primarily to the success of its sales and marketing strategies in the national
retail, private brand strategic alliance and direct sales programs.




                                       8

Revenues

     Revenues for the three and six months ended June 30, 1997 were $65.9
million and $127.5 million, respectively, compared to $49.1 million and $97.7
million for the three and six months ended June 30, 1996. Recurring revenues
for airtime, voice mail and other services for the three and six months ended
June 30, 1997 were $50.0 million and $96.5 million, respectively, compared to
$37.0 million and $70.7 million for the comparable periods ended June 30, 1996.
Revenues from equipment sales and activation fees for the three and six months
ended June 30, 1997 were $15.9 million and $31.1 million, respectively,
compared to $12.2 million and $27.0 million for the comparable periods ended
June 30, 1996. The increases in recurring revenues and revenues from equipment
sales and activation fees were primarily due to the rapid growth in the number
of units in service. The increase in equipment sales during the second quarter
of 1997 was somewhat offset by a decline in the average price per unit sold.
The Company expects equipment prices per unit generally to remain constant or
decline only slightly as sales volumes increase.

     The Company's ARPU was $8.50 and $7.97 in the second quarter of 1996 and
1997, respectively. Over the past year, the Company's ARPU has decreased
primarily as a result of an increase in subscribers added through the private
brand strategic alliance channel. This decrease in ARPU has been offset
somewhat by a higher mix of multi-city, regional and nationwide services as
well as increased sales of other value-added services such as voice mail and
toll-free numbers. Management anticipates that the Company's ARPU will decline
in the foreseeable future due to a continued higher mix of subscribers added
through private brand strategic alliance programs, which yield lower ARPU. ARPU
is lower for subscribers added through private brand strategic alliances
because these are generally high volume customers that are charged wholesale
airtime rates. However, because private brand strategic alliance partners are
responsible for selling and marketing costs, billing, collection and other
administrative costs associated with end-users, the Company incurs
substantially lower marketing and administrative costs with respect to such
subscribers.

Cost of Equipment Sold

     The cost of equipment sold for the three and six months ended June 30,
1997 was $20.2 million and $38.3 million, respectively, compared to $14.6
million and $31.7 million for the comparable periods ended June 30, 1996. The
change in 1997 was primarily due to an increase in the number of units sold.
The Company expects pager costs generally to remain constant, with modest
reductions in cost to the Company as a result of volume purchases. Management
anticipates that loss on equipment sold will generally remain constant on a per
unit basis for the foreseeable future.

Operating Expenses

     Technical expenses were $11.4 million and $22.2 million for the three and
six months ended June 30, 1997, respectively, compared to $8.8 million and
$16.9 million for the comparable 1996 periods. The increase was primarily due
to increased telecommunications and site expenses associated with servicing the
Company's expanded network and larger subscriber base. On an average monthly
cost per unit in service basis, technical expenses were $2.02 and $1.81 in the
second quarter of 1996 and 1997, respectively, compared to $2.02 and $1.83 for
the six months ended June 30, 1996 and 1997, respectively. The per unit
decrease was the result of increased operating efficiencies and economies of
scale achieved through the growth of the Company's subscriber base. During the
six months ended June 30, 1997, the Company incurred $3,000 in technical
expenses associated with the development of its two-way wireless messaging
services.

     Selling expenses for the three and six months ended June 30, 1997 were
$12.2 million and $24.8 million, respectively, compared to $10.5 million and
$19.9 million for the three and six months ended June 30, 1996, respectively.
This increase resulted from greater marketing and advertising costs related to
the growth in units sold as well as costs associated with the stocking of
additional retail outlets. The Company added 6,126 retail outlets from June 30,
1996 to June 30, 1997. During the six months ended June 30, 1996 and 1997, the
Company added 284,273 and 330,330 net new domestic units in service,
respectively. Management views the net loss on equipment sold to be a component
of selling and marketing expenses incurred to add new subscribers. See
"Management's Presentation of Results of Operations." Selling and marketing
expenses per net subscriber addition (including loss on equipment sales) were
$85 and $86 for the three and six months ended June 30, 1996, respectively,
compared to



                                       9
<PAGE>   10


$92 and $97 for the three and six months ended June 30, 1997, respectively.
This increase was due to losses recognized on the sale of pagers due to
stocking new retail outlets in the second quarter of 1997. The Company added
3,024 additional retail outlets in the three months ended June 30, 1997,
including additions from RadioShack(R) and Southland (7-Eleven) stores. The
losses on equipment sold are recognized when pagers are shipped to the
retailers, usually before the units are placed into service, thus increasing
selling expenses (including loss on the sale of equipment) per net subscriber
addition. During the three and six months ended June 30, 1997, the Company
incurred $150,000 and $244,000, respectively, in selling expenses associated
with its international operations (including loss on sale of equipment).

     General and administrative expenses (including costs associated with
customer service, field administration and corporate headquarters) for the
three and six months ended June 30, 1997 were $15.8 million and $31.6 million,
respectively, compared to $13.0 million and $26.0 million for the comparable
1996 periods. This increase was attributable to the Company's expansion of its
customer service call centers and other administrative capabilities to support
the growing subscriber base which required additional office space,
administrative personnel and customer service representatives. On an average
cost per month per unit in service basis, general and administrative expenses
were $3.00 and $2.52 in the second quarter of 1996 and 1997, respectively, and
$3.13 and $2.61 for the six months ended June 30, 1996 and 1997, respectively.
The per unit decrease was a result of increased operating efficiencies and
economies of scale achieved through the growth of the Company's subscriber
base. During the six months ended June 30, 1997, the Company incurred $13,000
in general and administrative expenses associated with the development of its
two-way wireless messaging services.

     Depreciation and amortization for the three and six months ended June 30,
1997 were $7.2 million and $14.0 million, respectively, compared to $4.9
million and $9.2 million for the comparable periods ended June 30, 1996. The
increase resulted from the expansion of the Company's network infrastructure
including transmitter and terminal equipment, as well as the purchase and
development of a new centralized administrative system in 1996 and the first
six months of 1997. As an average cost per month per unit in service,
depreciation and amortization was $1.14 and $1.15 in the second quarter of 1996
and 1997, respectively, and was $1.11 and $1.16 for the six months ended June
30, 1996 and 1997, respectively. During the three and six months ended June 30,
1997, the Company incurred $45,000 and $86,000, respectively, in depreciation
expenses associated with the development of its two-way wireless messaging
services.

Interest Expense

     Consolidated interest expense for the three and six months ended June 30,
1997 was $9.3 million and $18.3 million, respectively, compared to $8.9 million
and $17.3 million for the comparable periods ended June 30, 1996. The increase
in 1997 was primarily the result of increased interest expense related to the
12 1/4% Senior Discount Notes due 2003 issued by PageMart in October 1993 (the
"12 1/4% Notes") and the 15% Senior Discount Notes due 2005 issued by the
Company in January 1995 (the "15% Notes"). Interest expense related to the 12
1/4% Notes waS $3.3 million and $3.7 million for the three months ended June
30, 1996 and 1997, respectively, and was $6.5 million and $7.3 million for the
six months ended June 30, 1996 and 1997, respectively. Interest expense related
to the 15% Notes was $4.5 million and $5.4 million for the three months ended
June 30, 1996 and 1997, respectively, and was $8.9 million and $10.2 million
for the six months ended June 30, 1996 and 1997, respectively.

Net Loss

     The Company sustained consolidated net losses for the three and six months
ended June 30, 1997 of $11.1 million and $23.2 million, respectively, compared
to $12.1 million and $23.7 million for the three and six months ended June 30,
1996, respectively, principally due to the cost of funding the growth rate of
the Company's subscriber base which resulted in an increase in units sold,
selling and marketing expenses, operating expenses and interest expense.

MANAGEMENT'S PRESENTATION OF RESULTS OF OPERATIONS

Comparison with GAAP Presentation

     The Company's unaudited condensed consolidated financial statements for
the three and six months ended June 30, 1996 and 1997 included elsewhere in
this report, have been prepared in accordance with generally accepted
accounting principles ("GAAP"). For internal management purposes the Company
prepares statements of operations that are derived from the Company's GAAP
financial statements but are reordered in a format that management uses for its
internal review of the Company's performance and that management believes is
useful in understanding the Company's results.

     Management believes that operating profit before selling expenses is a
meaningful indicator of the profitability of the Company's installed base of
units in service because it measures the recurring revenues received for
services less the costs (including depreciation and amortization) associated
with servicing that installed base. Operating profit before selling expenses
per subscriber per month for the Company's one-way operations has grown from
$1.66 during the third quarter of 1995 to $2.48 during the second quarter of
1997 due primarily to the Company's increase in subscribers and resulting
benefits in economies of scale.

     In addition, selling and marketing expenses (including loss on equipment
sold) provide a measure of the costs associated with obtaining new subscribers
that the Company needs to generate the incremental recurring revenue necessary
to achieve profitability. Under the GAAP presentation, recurring revenues and
equipment and activation revenues are aggregated and are not separately
compared to the costs associated with each.

     The items included in Management's Presentation of the Results of
Operations and their derivation from financial information presented in
accordance with GAAP are described below.

     Recurring Revenues. Recurring revenues include periodic fees for airtime,
     voice mail, customized coverage options, toll-free numbers, excess usage
     fees and other recurring revenues and fees associated with the subscriber
     base. Recurring revenues do not include equipment sales revenues or
     initial activation fees. Recurring revenues are the same under both the
     management and GAAP presentations.

     Technical Expenses. This item is the same under the management and GAAP
     presentations.

     General and Administrative Expenses. This item is the same under the
     management and GAAP presentations.

     Depreciation and Amortization. This item is the same under the management
     and GAAP presentations.

     Operating Profit Before Selling Expenses. Operating profit before selling
     expenses under the management presentation is equal to recurring revenues
     less technical expenses, general and administrative expenses and
     depreciation and amortization. Operating profit before selling expenses is
     not derived pursuant to GAAP.

     Selling Expenses. Selling expenses under the management presentation
     represent the cost to the Company of selling pagers and other messaging
     units to a customer, and are equal to selling costs (sales compensation,
     advertising, marketing, etc.) plus costs of units sold less revenues from
     equipment sales and activation fees. As described above, the Company sells
     rather than leases substantially all of the one-way messaging equipment
     used by subscribers. Selling expenses under the management presentation
     are not derived pursuant to GAAP. Net loss on equipment sales is not
     included in the GAAP presentation of selling expenses.

     Operating Income (Loss). This item is the same under the management and
     GAAP presentations.

     EBITDA. EBITDA represents earnings (loss) before interest, taxes,
     depreciation and amortization. EBITDA is a financial measure commonly used
     in the paging industry. EBITDA is not derived pursuant to GAAP and
     therefore should not be construed as an alternative to operating income,
     as an alternative to cash flows from operating activities (as determined
     in accordance with GAAP) or as a measure of liquidity. The calculation of
     EBITDA does not include the commitments of the Company for capital
     expenditures and payment of debt and should not be deemed to represent
     funds available to the Company. In the fourth quarter of 1995, the
     Company's EBITDA from its one-way operations became positive for the first
     time.

(1)  Expenses reflected in this table are for the Company's international
     headquarters operations. The Company accounts for its investments in
     Canada under the equity method. Consequently, the Company's share of
     expenses from its Canadian operations are not reflected in this table.

SEASONALITY

     Pager usage is slightly higher during the spring and summer months, which
is reflected in higher incremental usage fees earned by the Company. The
Company's retail sales are subject to seasonal fluctuations that affect retail
sales generally. Otherwise, the Company's results are generally not
significantly affected by seasonal factors.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's operations have historically required substantial capital
investment for the development and installation of its wireless communications
network, the procurement of messaging equipment and expansion into new and
existing markets. To date, these investments by the Company have been funded by
the proceeds from the issuance of common stock, preferred stock, the 12 1/4%
Notes and the 15% Notes, as well as borrowings under vendor financing and
revolving credit agreements.

     Capital expenditures for the six months ended June 30, 1997 were $23.4
million compared to $27.2 million for the six months ended June 30, 1996.
Capital expenditures for the six months ended 1997 include approximately $9.9
million related to the development of two-way messaging services, $8.9 million
for the Company's one-way network and $4.6 million for the development of the
Company's new administrative system. During December 1995, the Company
committed to purchase $40 million in network infrastructure equipment from a
significant vendor from December 1, 1995 to October 31, 1999 (the "Vendor
Commitment"). Through June 30, 1997, the Company has purchased $21.7 million of
network infrastructure under this purchase commitment.

     The Company's net cash provided by operating activities for the six months
ended June 30, 1997 was $2.3 compared with the net cash used of $6.0 million
for the six months ended June 30, 1996. Net cash used in investing activities
was $24.1 million for the six months ended June 30, 1997 compared with $26.8
million for the comparable 1996 period. Of the $24.1 million used in investing
activities in 1997, $23.4 million was for capital expenditures. Net cash
provided by financing activities, including borrowings and equity issuances was
$6.1 million for the six months ended June 30, 1997 compared with the $55.6
million for the six months ended June 30, 1996. Long-term obligations, less
current maturities, increased by approximately $21.9 million during the six
months ended June 30, 1997. The increase resulted from the accretion of the 15%
Notes of $10.0 million, the accretion of the 12 1/4% Notes of $7.1 million and
$4.8 million of borrowings on a vendor financing arrangement.

     In March 1997, PageMart entered into a vendor financing arrangement with
an infrastructure vendor (the "Vendor Financing Arrangement"), providing for
the financing of one-way or two-way infrastructure equipment over a period of
60 months up to a maximum aggregate amount of $30 million. Borrowings under the
Vendor Financing Arrangement are secured by the equipment purchased. The
interest rate applicable to such financing is equal to the sum of 7.00% and the
London interbank offered rate ("LIBOR") as published in the Wall Street Journal
for three month maturities or the sum of 4.25% and the U.S. prime rate of
interest as published in the Wall Street Journal. The weighted average interest
rate in effect on June 30, 1997 with respect to the Vendor Financing
Arrangement was 12.5%.

     As of June 30, 1997, the Company had $5.7 million outstanding under a
vendor financing arrangement and its indebtedness under the 12 1/4% Notes was
$115.1 million and its indebtedness under the 15% Notes was $142.7 million.

     The 12 1/4% Notes, which are unsecured senior obligations of PageMart,
mature in 2003 and were issued at a substantial discount from their principal
amount at maturity. The accretion of original issue discount on the 12 1/4%
Notes will cause an increase in indebtedness from June 30, 1997 to November 1,
1998 of $21.4 million. From and after November 1, 1998, interest on the 12 1/4%
Notes will be payable semiannually, in cash.

     The 15% Notes, which are unsecured senior obligations of Wireless, mature
in 2005 and were issued at a substantial discount from their principal amount
at maturity. The accretion of original issue discount on the 15% Notes will
cause an increase in indebtedness from June 30, 1997 to February 1, 2000 of
$64.6 million. From and after February 1, 2000, interest on the 15% Notes will
be payable semiannually, in cash.

     In May 1995, the Company entered into a four year Revolving Credit
Agreement (the "Revolving Credit Agreement") with BT Commercial Corporation, as
Agent, and Bankers Trust Company, as Issuing Bank, which provides for a $50
million revolving line of credit. As of June 30, 1997 there were no loans
outstanding under the Revolving Credit Agreement. The maximum amount available
under the Revolving Credit Agreement at any time


                                      14
<PAGE>   15


is limited to a borrowing base amount equal to the lesser of (i) 80% of
eligible accounts receivable plus 50% eligible inventory owned by Wireless, and
(ii) an amount equal to the service contribution as defined in the Revolving
Credit Agreement of Wireless and its subsidiaries for the immediately preceding
three-month period times 4.0. As of June 30, 1997, the amount available under
the Revolving Credit Agreement was $36.1 million. In the event Wireless
exercised its option to increase its borrowing base by purchasing inventory and
accounts receivable from PageMart, the maximum amount available under the
Revolving Credit agreement would have been $41.0 million at June 30, 1997.
Management anticipates borrowing under the Revolving Credit Agreement during
the third quarter of 1997.

     The indenture under which the 15% Notes were issued (the "15% Indenture"),
the indenture under which the 12 1/4% Notes were issued (the "12 1/4%
Indenture"), the Revolving Credit Agreement and the Vendor Financing AgreemENT
contain certain restrictive covenants that, among other things, limit the
ability of the Company to incur indebtedness, pay dividends, repurchase capital
stock, engage in transactions with stockholders and affiliates, create liens,
sell assets, enter into leases and engage in mergers and consolidations, and
the Revolving Credit Agreement requires the Company to maintain certain
financial ratios and limits the ability of the Company to make capital
expenditures. In addition, the 12 1/4% Indenture prohibits PageMart from paying
any dividends or making other distributions on its capital stock, making loans
to Wireless, merging or consolidating with Wireless or assuming or guaranteeing
any obligations of Wireless unless PageMart is in compliance with certain
interest coverage ratios and certain other requirements. PageMart may, however,
sell its assets to Wireless in transactions that are arm's length in nature.
Wireless is currently a holding company with no business or operations of its
own. Because all of Wireless's operations are conducted through its
subsidiaries, Wireless's cash flow and consequently its ability to service
debt, is almost entirely dependent upon the earnings of its subsidiaries and
the distribution of those earnings or upon loans or other payment of funds by
those subsidiaries to Wireless. Wireless's subsidiaries are separate and
distinct legal entities and have no obligation, contingent or otherwise, to pay
any amounts due pursuant to Wireless's obligations or to make any funds
available therefor, whether by dividends, loans or other payments. Until the
maturity of the 12 1/4% Notes, which mature on November 1, 2003, earlier
repayment of such indebtedness or compliance with the requirements of such debt
instruments, Wireless will be unable to use any amount of cash generated by the
operations of PageMart and its subsidiaries. However, currently Wireless does
not have significant cash requirements until March 1999 when the Revolving
Credit Agreement matures.

     On November 15, 1995, the Company purchased through PageMart
International, Inc., 200,000 voting shares of common stock of PageMart Canada,
which represents 20% of the ownership of PageMart Canada. PageMart
International, Inc. also owns 33% of the voting common stock of the holding
company parent of PageMart Canada ("Canada Holding"), which owns the remaining
80% of the voting common stock of PageMart Canada. The Company's investment in
Canada Holding and PageMart Canada totals approximately $3.7 million.

     As of June 30, 1997, the Company had approximately $6.9 million in cash
and cash equivalents. The Company's cash balances and borrowings under the
Revolving Credit Agreement and the Vendor Financing Arrangement are expected to
be sufficient to fund the Company's one-way operations and related capital
requirements through 1997. The Company anticipates its one-way messaging
operations will generate sufficient cash flows to fund one-way capital
expenditures for 1998. The Company's two-way messaging operations are expected
to require additional capital in 1998. The Company anticipates funding a
portion of its two-way messaging operations with available borrowings under the
Revolving Credit Agreement, Vendor Financing Arrangement and from any excess
cash generated from the Company's one-way messaging operations.

     As the Company begins development and implementation of narrowband
personal communications services, the Company expects to incur additional
operating losses during the start-up phase for such services and it will
continue to be necessary for the Company to make substantial investments. The
Company anticipates requiring additional sources of capital to fund the
construction of a two-way messaging network, including expenditures relating to
the buildout requirements of the Federal Communications Commission ("FCC"). The
Company anticipates investing $75 to $100 million through fiscal 1998 to test
and construct a two-way transmission network. Thereafter, the Company
anticipates that the two-way operations may require up to $100 million of
additional investment to fund operations, marketing and to add capacity to the
network as the Company's two-way customer base grows. The Company expects to
lease rather than sell a portion of its two-way messaging units. The Company


                                      15
<PAGE>   16


expects to require additional financing to complete the buildout, which may
include additional vendor financing or entering into joint venture
arrangements, however, there can be no assurance that sufficient financing will
be available to the Company. The Company's ability to incur indebtedness is
limited by the covenants contained in the 15% Indenture, the 12 1/4% Indenture
and the Revolving Credit Agreement. As a result any additional financing may
need to be equity financing. The Company does not anticipate any significant
revenues from two-way services in 1997.

     Future revenues, costs, product mix and new product acceptance are all
influenced by a number of factors which are inherently uncertain and difficult
to predict. While management believes that it will be able to secure adequate
financing and achieve profitable operations, no assurance can be given that
financing for such investments will be available. No assurance can be given
that the Company's strategy will be implemented as currently planned or that
the Company's operations will generate positive cash flows.

     This Form 10-Q contains statements that constitute forward-looking
statements. Readers are cautioned that such forward-looking statements involve
risk and uncertainties, and are subject to change based on various important
factors. The following factors, among others, in some cases have affected and
in the future could affect the Company's financial performance and actual
results and could cause actual results for 1997 and beyond to differ materially
from those expressed in any such forward-looking statements - economic
conditions generally in the United States and consumer confidence; the ability
of the Company to manage its debt levels; the impact of technological change in
the telecommunications industry; the future cost of network infrastructure and
subscriber equipment; the impact of competition and pricing of paging and
wireless services; the timely development and acceptance of new products;
changes in regulation by the FCC and various state regulatory agencies and the
ability of the Company to obtain financing to construct, operate and market the
transmission network for two-way services.

     FOR VALUE RECEIVED, PageMart, Inc., a Delaware corporation ("Maker"),
hereby promises to pay to the order of GLENAYRE ELECTRONICS, INC., a Colorado

hereunder, together with accrued interest from the date or dates such funds
have been advanced until paid in full, on the principal amount from time to

computed on the basis of a three hundred sixty (360) day year.

     All capitalized terms used but not otherwise defined herein shall have the
meanings ascribed thereto in Section 9.

     This Note evidences purchase money indebtedness of Maker to Glenayre for
Equipment purchased by Maker from Glenayre in accordance with the terms of the
invoices and sales order(s) to be referenced on Exhibit A to each Schedule to
this Note. Upon the execution of a Schedule in the form attached hereto, the
terms and conditions contained herein, together with any and all additional or
specific terms and conditions contained therein, shall apply to that Schedule
and shall be incorporated into and have the same force and effect as to that
Schedule as though expressly set forth therein. This Note has such further
terms, is entitled to the benefits of such agreements and covenants, and is
subject to such provisions, as are set forth below:

     SECTION 1. PAYMENT PROVISIONS.

     1.3 Mandatory Prepayments. There shall be a mandatory Prepayment upon each
occurrence of any of the following events, in such amounts and to be applied as
set forth below in this Section 1.3:

     (a) If any of the Collateral is sold or otherwise disposed of as permitted
hereunder, then one hundred percent (100%) of the net cash proceeds from such
sale or disposition (that is, the gross sales proceeds less any customary
expenses incurred in connection with such sale or disposition) shall be paid to
Glenayre as a mandatory Prepayment, unless such proceeds are used to purchase
equipment from Glenayre within 180 days; or

     (b) If any insurance proceeds are received as a result of any loss or
damage to the Collateral, then one hundred percent (100%) of such proceeds
shall be paid to Glenayre as a mandatory Prepayment, unless such proceeds are
used to purchase replacement equipment from Glenayre within 180 days or, in the
case of proceeds received as a result of damage, used to reasonably and
promptly repair the Collateral so damaged.

     (c) If Parent, Maker or any of Parent's or Maker's Subsidiaries shall
receive in excess of $100 million from any net proceeds from an offering or
issuance of any Capital Stock after the date hereof, Maker shall apply 100% of
the proceeds in excess of $100 million thereof to the prepayment of this Note,
not to exceed the principal balance at the time of prepayment.

     1.4 Application of Payments. All payments made under Section 1.1 shall be
applied first to interest (in arrears) and then to principal. All Prepayments
shall be applied in order of scheduled maturities. Maker shall not be permitted
to reborrow any amounts paid or prepaid hereunder.

     1.5 Commitment Fee. Maker agrees to pay to Glenayre a commitment fee equal

fully earned when due and nonrefundable when paid, and computed on the basis of
a year of 360 days for the actual number of days elapsed.

     SECTION 3. SECURITY. This Note is and shall at all times be secured by a
first priority purchase money security interest in the Collateral pursuant to
the following terms and conditions:

     (a) Maker hereby grants a security interest in the Collateral and will,
upon request of Glenayre, execute such additional security agreements,
financing statements, notices of lien, notices of assignment, transfer
endorsements, conveyances, documents of title and continuations or amendments
to any of the foregoing (collectively, "Lien Documents"), and other documents
(and pay the filing fees or similar fees of filing or recording the same in all
public offices deemed necessary by Glenayre) and do such other acts and things,
all as Glenayre may from time to time reasonably request to establish and
maintain valid perfected security interests in the Collateral as set forth on
Exhibit A to each Schedule to this Note to secure the payment of the
obligations and




                                       3
<PAGE>   4



liabilities of Maker to Glenayre under this Note. Maker hereby constitutes and
appoints Glenayre (and the chairman of the board, the vice chairman of the
board, the chief executive officer, the president or any vice president of
Glenayre from time to time) as its attorney-in-fact with full power and
authority to execute and deliver all documents to the extent necessary to
perfect and keep perfected the security interests created hereby. This power of
attorney hereby granted is a special power of attorney coupled with an interest
and shall be irrevocable by Maker.

     (b) There are no Lien Documents now on file in any public office relating
to all or any portion of the Collateral, and so long as any amount remains
unpaid on any of the obligations secured hereby, Maker shall not execute any
Lien Documents, describing or attempting to describe the Collateral secured
herein, except for Lien Documents filed in favor of Glenayre.

     (c) Maker will, concurrently with the granting of this security interest
in the Collateral, place notations on its books and records disclosing the
security interest of Glenayre in such Collateral.

     (d) Maker will reimburse Glenayre for all reasonable out-of-pocket
expenses, including reasonable attorneys' fees and disbursements, incurred by
Glenayre in seeking to collect any amounts due hereunder or enforcing any
rights hereunder.

     (e) Maker shall deliver written notice to Glenayre of any location where
the Equipment will be located other than the locations set forth on Exhibit A
hereto or on Exhibit A to any Schedule to this Note within 60 days of receiving

     (f) This Note shall create a continuing security interest in the
Collateral and shall (i) remain in full force and effect until payment and
performance in full of the obligations of Maker under the Note (ii) be binding
upon Maker, its successors and assigns and (iii) inure, together with the
rights and remedies of Glenayre hereunder, to the benefit of Glenayre, subject
to the terms and conditions of the Note. Glenayre may assign or transfer any
rights and obligations under this Note or the Lien Documents or any rights in
Collateral held by it to any other Person upon written consent of Maker, which
consent is not to be unreasonably withheld. Under no circumstances should Maker
be required to provide such consent in violation of any existing agreement. In
case of any such transfer, such other Person shall thereupon become vested with
all the benefits in respect thereof granted to Glenayre herein or otherwise.
Nothing set forth herein is intended or shall be construed to give to any other
party any right, remedy or claim under, to or in respect of this Note or any
Collateral. Upon the payment in full of the obligations secured hereby, the
security interest granted hereby shall terminate and all rights to the
Collateral shall revert to Maker. Upon the termination of any such security
interest, or upon Glenayre's release of any of the Collateral in accordance
with the terms of this Note, Glenayre shall promptly return to Maker, at
Maker's expense, such of the Collateral (and, in the case of a release, such of
the released Collateral) held by Glenayre as shall not have been sold or
otherwise applied pursuant to the terms



                                       4
<PAGE>   5



hereof. Glenayre will, at Maker's expense, execute and deliver to Maker such
other documents as Maker shall reasonably request to evidence such termination
or release, as the case may be.

     SECTION 4. LATE CHARGES AND DEFAULT INTEREST. Glenayre may collect a late
charge of three percent (3%) of each installment of principal and/or interest
hereunder or portion thereof more than fifteen (15) days in arrears to cover
the administrative expense in handling such delinquent payment. At Glenayre's
option, the rate applicable to this Note shall become a rate equal to the
Default Rate commencing with and continuing during any Event of Default.

warrants to Glenayre that:

     SECTION 6. AFFIRMATIVE COVENANTS. Maker agrees that until this Note is
paid in full and satisfied, unless Glenayre shall otherwise consent in writing:

     6.1 Maintain Corporate Existence. Maker will maintain its corporate

                                       6
<PAGE>   7



     (a) Annual Statements. Within ninety (90) days after the close of each
fiscal year, consolidated financial reports of Parent, Maker and its
Subsidiaries, including balance sheets, income statements and statements of
cash flows based on Generally Accepted Accounting Principles, as filed with the
Securities Exchange Commission.

     (b) Quarterly Statements. Within forty-five (45) days after the close of
each fiscal quarter of each year (except for the fourth and final quarter) a
consolidated balance sheet, income statement and statement of cash flows of
Parent, Maker and its Subsidiaries certified by the chief financial officer of
Maker to be correct and accurate and prepared in accordance with Generally
Accepted Accounting Principles, as filed with the Securities Exchange
Commission.

     (c) Other. Such other information respecting the financial condition,
business affairs and operations of Maker and its Subsidiaries as Glenayre may
from time to time reasonably request.

     6.3 Payment of Taxes. Maker will, and will cause each of its Subsidiaries
to, comply with all statutes and governmental regulations and pay all taxes,
assessments, governmental charges, claims for labor, supplies, rent and any
other obligation which, if unpaid, might become a lien against any of their
respective properties, except (i) liens for taxes not yet due and payable and
(ii) liabilities being contested in good faith with due diligence and against
which reserves in amounts required under Generally Accepted Accounting
Principles have been established.

     6.4 Insurance. Maker shall obtain and maintain for the entire term of this
Note, at its own expense, property damage and liability insurance against loss
or damage to the Equipment including, without limitation, loss by fire
(including so-called extended coverage), theft and such other risks of loss as
are customarily insured by "all risks" policies on the type of Equipment sold
hereunder and by businesses in which it is engaged in such amounts, in such
form and with such insurers as shall be reasonably satisfactory to Glenayre,
but the amount of insurance covering damage to or loss of the Equipment shall
not be less than the greater of (i) the full replacement value of the Equipment
or (ii) the total payments then remaining unpaid hereunder. Each insurance
policy will name Maker as an insured and Glenayre as an additional insured and
loss payee thereof and shall contain a clause requiring the insurer to give to
Glenayre at least thirty (30) days prior written notice of any alteration of
the terms of such policy or of the cancellation thereof. At Glenayre's request,
Maker shall provide Glenayre with a Certificate of Insurance or other evidence
satisfactory to Glenayre that such insurance coverage is in effect. If Maker
fails to provide evidence of insurance satisfactory to Glenayre, Glenayre may
purchase or otherwise provide such insurance and the cost thereof to Glenayre
shall be deemed an additional cost hereunder and shall be payable by Maker on
demand. Maker hereby appoints Glenayre its agent and attorney to make claims
and receive payment in accordance with the provisions of any policy so
purchased or provided by Glenayre. Maker further agrees to give Glenayre prompt
notice of any damage to, or loss of, the Equipment, or any part thereof. All
proceeds of insurance paid or payable under any insurance policy shall be paid
to Glenayre for the benefit of Maker. All insurance proceeds shall be



                                       7
<PAGE>   8



applied as a mandatory Prepayment to the extent required by the terms of
Section 1.3. Notwithstanding the application of any insurance proceeds to the
payment of a portion of the indebtedness evidenced hereby, the unpaid portion
of said indebtedness shall remain in full force and effect, and Maker shall not
