                                  THE COMPANY
 
     Metrocall is currently the sixth largest paging company in the United
States, based on 1,109,647 pagers in service at June 30, 1996, providing local,
regional and nationwide paging and other wireless messaging services. Metrocall
currently operates regional and nationwide paging networks throughout the United
States and has historically concentrated its selling efforts in four operating
regions: (i) the Northeast (Massachusetts through Delaware); (ii) the
Mid-Atlantic (Maryland and the Washington, D.C. metropolitan area); (iii) the
Southeast (Virginia and Florida); and (iv) the West (California, Nevada and
Arizona). Through the Metrocall Nationwide Wireless Network, Metrocall can
provide paging services in approximately 864 U.S. cities which include the top
100 Standard Metropolitan Statistical Areas.
 
     Metrocall has announced a pending acquisition which, when consummated, will
add approximately 220,000 subscribers to its base of pagers in service. In
addition, one acquisition was consummated on July 16, 1996 and another was
consummated on August 30, 1996, adding approximately 140,000 and 100,000
subscribers, respectively. The merger (the "A+ Network Merger") of the Company
and A+ Network, Inc. ("A+ Network") is also pending. Through the acquisitions
and the A+ Network Merger, Metrocall will expand its operations into the
Midwest, Southwest and Southeast, while strengthening its existing customer base
in the Northeast. On a combined basis (pro forma for all acquisitions and the A+
Network Merger), the Company would service a total subscriber base consisting of
approximately 2.2 million units in service, and would constitute the fourth
largest paging company in the United States. Metrocall was organized as a
Delaware corporation in October 1982. The Company's Common Stock is traded on
the NNM under the symbol "MCLL". The Company's principal executive offices are
located at 6677 Richmond Highway, Alexandria, Virginia 22306 and its telephone
number is (703) 660-6677.

                                  RISK FACTORS
 
     In evaluating the proposed transaction, prospective purchasers should
carefully consider the following factors as well as the other matters discussed
in this Prospectus.
 
SUBSTANTIAL INDEBTEDNESS
 
     Metrocall currently has incurred approximately $222 million in
indebtedness, and will assume approximately $125 million of A+ Network
indebtedness in the A+ Network Merger. In addition, Metrocall expects to incur
additional indebtedness as a result of the Page America Acquisition (estimated
at $55 million). Metrocall has a new credit facility (the "New Credit Facility")
in the principal amount of $350 million (of which $67 million was drawn as of
September 26, 1996 and is included in the incurred indebtedness described
above), and intends to use funds available under this facility to fund the
pending acquisition and/or to refinance indebtedness of A+ Network that
Metrocall will assume in the A+ Network Merger. The Company may also incur
additional indebtedness (in the form of draws on the New Credit Facility or
otherwise) in connection with future acquisitions or for other purposes.
However, the ability to incur additional indebtedness (including draws on the
New Credit Facility) is subject to certain limitations in the agreements
relating to existing indebtedness and Metrocall currently may not incur
additional indebtedness. In particular, Metrocall cannot assume the indebtedness
of A+ Network in connection with the A+ Network Merger unless certain financial
covenants are not exceeded after assumption of the indebtedness. In order to be
in compliance with these covenants after the A+ Network Merger, reported cash
flow of Metrocall and A+ Network must increase to a level that is sufficient to
allow Metrocall to assume the indebtedness of A+ Network or the overall level of
indebtedness that would exist after the A+ Network Merger must be reduced by
raising additional equity capital or other means. See "Need for Additional
Capital." Moreover, the ability of the Company to meet its debt service and
other obligations will be dependent upon the future performance of the Company
and its cash flows from operations, which will be subject to financial, business
and other factors, certain of which are beyond its control, such as prevailing
economic conditions. No assurance can be given that, in the event the Company
were to require additional financing, such additional financing would be
available on terms permitted by agreements relating to existing indebtedness or
otherwise satisfactory to the Company. See "RECENT DEVELOPMENTS -- New Credit
Facility."
 
NEED FOR ADDITIONAL CAPITAL
 
     As set forth above, Metrocall is seeking to raise additional equity capital
in order to insure that it will remain in compliance with certain debt covenants
after completion of the A+ Network Merger. In addition, only $100 million of the
$350 million under the New Credit Facility is available (subject in any event to
compliance with certain financial ratios) until Metrocall raises at least $25
million in additional equity capital, and this capital must be raised before
Metrocall can complete the Page America Acquisition. The New Credit Facility
will also require Metrocall to raise a further $25 million in equity capital if
Metrocall's ratio of cash flow to interest expense is less than 2.0 to 1 for the
quarter ended June 30, 1997. See "RECENT DEVELOPMENTS -- New Credit Facility."
Metrocall is exploring options for raising up to $50 million of additional
equity financing, but there can be no assurance that it will be successful in
doing so. Such additional equity may be in the form of additional shares of the
Common Stock, preferred stock, or some other instrument. Any equity issued in
the form of preferred stock would have preference as to dividends and
liquidating distributions over the Common Stock and may contain other terms
adversely affecting holders of the Common Stock.
 
CHALLENGES OF BUSINESS INTEGRATION
 
     Metrocall has implemented a strategy of acquiring other paging companies
and intends to continue to seek additional acquisition candidates. The process
of integrating acquired businesses into the Company's operations may result in
unforeseen difficulties and may require a disproportionate amount of
management's attention and the Company's resources.
 
                                        4
<PAGE>   6
 
     No assurance can be given that additional suitable acquisition candidates
can be identified, financed and purchased on acceptable terms, or that future
acquisitions, if completed, will be successful. Metrocall also intends to
continue to pursue internal growth through expansion of its paging operations.
The Company's continued internal growth will depend, in part, upon its ability
to attract and retain skilled employees, and the ability of the Company's
officers and key employees to manage successfully rapid growth and to implement
appropriate management information systems and controls. If the Company were
unable to attract and retain skilled employees, manage successfully rapid growth
and/or implement appropriate systems and controls, the Company's operations
could be adversely affected.
 
     The paging industry is currently undergoing significant consolidation as
various participants seek to accomplish growth strategies similar to those of
Metrocall. Although Metrocall is not currently engaged in any negotiations with
respect to a business combination involving the acquisition of Metrocall and
intends to continue to pursue its own business strategy, an unsolicited proposal
to acquire the Company could cause a distraction of management of the Company
and impede the Company's ability to accomplish its strategic goals and
objectives and could cause significant volatility in the price of the Common
Stock.
 
POSSIBLE IMPACT OF COMPETITION AND TECHNOLOGICAL CHANGE
 
     The Company will face competition from other paging companies in all
markets in which it operates. The wireless communications industry is a highly
competitive industry, with price being the primary means of differentiation
among providers of numeric messaging services (which account for the majority of
the Company's current revenues). Companies in the industry also compete on the
basis of coverage area, enhanced services, transmission quality, system
reliability and customer service. Certain of the Company's competitors, which
include regional and national paging companies, will possess greater financial,
technical, marketing and other resources than the Company. In addition, other
entities offering wireless two-way communications technology, including cellular
telephone and specialized mobile radio services, will also compete with the
paging services the Company provides. There can be no assurance that additional
competitors will not enter markets served by the Company or that the Company
will be able to compete successfully. In this regard, certain long distance
carriers have announced their intention to market paging services jointly with
other telecommunications services.
 
     The wireless communications industry is characterized by rapid
technological change. Future technological advances in the wireless
communications industry could create new services or products competitive with
the paging and wireless messaging services provided or to be developed by the
Company. Recent and proposed regulatory changes by the FCC are aimed at
encouraging such new services and products.
 
     In particular, in 1994, the FCC began auctioning licenses for new personal
communications services ("PCS"). The FCC's rules also provide for the private
use of PCS spectrum on an unlicensed basis. PCS will involve a network of small,
low-powered transceivers placed throughout a neighborhood, business complex,
community or metropolitan area to provide customers with mobile voice and data
communications. There are two types of PCS, narrowband and broadband. Narrowband
PCS is expected to provide enhanced or advanced paging and messaging
capabilities, such as "acknowledgment paging" or "talk-back" paging. Broadband
PCS is expected to provide new types of communications devices that will include
multi-functional portable phones and imaging devices, which may also have paging
and messaging capabilities. PCS systems may compete directly and indirectly with
the Surviving Corporation.
 
     Moreover, changes in technology could lower the cost of competitive
services and products to a level where the Company's services and products would
become less competitive or to where the Company would be required to reduce the
prices of its services and products. There can be no assurance that the Company
will be able to develop or introduce new services and products to remain
competitive or that the Company will not be adversely affected in the event of
such technological developments.
 
     Technological change also may affect the value of the pagers owned by the
Company and leased to its subscribers. If the Company's subscribers requested
more technologically advanced pagers, the Company could incur additional
inventory costs and capital expenditures if it were required to replace pagers
leased to its subscribers within a short period of time.

HISTORY OF NET LOSSES
 
     Metrocall sustained net losses of $2.2 million, $2.4 million and $20.1
million for the years ended December 31, 1993, 1994 and 1995, respectively, and
a loss of $18.6 million for the six months ended June 30, 1996. No assurance can
be given that losses can be reversed in the future. In addition, at June 30,
1996, Metrocall's accumulated deficit was $65.5 million. Metrocall's business
requires substantial funds for capital expenditures and acquisitions that result
in significant depreciation and amortization charges. Additionally, substantial
levels of borrowing, which will result in significant interest expense, are
expected to be outstanding in the foreseeable future. Accordingly, net losses
are expected to continue to be incurred in the future. There can be no assurance
that the Company will be able to operate profitably at any time in the future.
 
SUBSCRIBER TURNOVER
 
     The results of operations of paging service providers, such as Metrocall,
can be significantly affected by subscriber cancellations and by subscribers who
switch their service to other carriers. In order to realize net growth in
subscribers, disconnected subscribers must be replaced and new subscribers must
be added. The sales and marketing costs associated with attracting new
subscribers are substantial relative to the costs of providing service to
existing customers. Because Metrocall's business is characterized by high fixed
costs, disconnections directly and adversely affect operating cash flow. An
increase in its subscriber cancellation rate may adversely affect the Company's
results of operations.
 
POTENTIAL FOR CHANGE IN REGULATORY ENVIRONMENT
 
     The Company's paging operations will be subject to regulation by the FCC
and, to a lesser extent, by various state regulatory agencies. There can be no
assurance that those agencies will not adopt regulations or take actions that
would have a material adverse effect on the business of the Company. Changes in
regulation of the Company's paging business or the allocation of radio spectrum
for services that compete with the Company's business could adversely affect the
Company's results of operations. For example, the FCC is currently engaged in a
rule making proceeding whereby it proposes to issue paging licenses on a
wide-area basis by competitive bidding (i.e., auctions). Although Metrocall
believes that the proposed rule changes may simplify the Company's regulatory
compliance burdens, particularly regarding adding or relocating transmitter
sites, those rule changes may also increase the Company's costs of obtaining
paging licenses.
 
NO ANTICIPATED STOCKHOLDER DISTRIBUTIONS
 
     It is not anticipated that the Company will pay cash dividends in the
foreseeable future. Certain covenants in the Company's bank credit agreement
prohibit the payment of dividends by Company. See "RECENT DEVELOPMENTS -- New
Credit Facility."
 
RELIANCE ON KEY PERSONNEL
 
     Metrocall is dependent upon the efforts and abilities of a number of its
current key management, sales, support and technical personnel. The success of
the Company will depend to a large extent upon its ability to retain and
continue to attract key employees. The loss of certain of these employees or the
Company's inability to retain or attract key employees in the future could have
an adverse effect upon the Company's operations.
 
POSSIBLE VOLATILITY OF STOCK PRICE; SHARES ELIGIBLE FOR FUTURE SALE
 
     Since the Metrocall Common Stock became publicly traded in July 1993, the
closing price has ranged from a low of $6 1/4 per share to a high of $29 per
share. The market price of the Metrocall Common Stock may be volatile due to,
among other things, technological innovations affecting the paging industry, the
Company's acquisition strategy and the shares being registered pursuant to this
registration statement. In addition, Metrocall currently has effective
registration statements with respect to approximately 6.7 million shares of
Metrocall Common Stock held by certain stockholders of Metrocall in addition to
the approximately 1.4 million shares registered by the registration statement of
which this Prospectus is a part. In addition, Metrocall expects to issue up to
approximately 9,042,260 additional shares of Common Stock in connection
 
                                        6
<PAGE>   8
 
with the A+ Network Merger. Metrocall also expects to issue additional shares of
Metrocall Common Stock in connection with the Page America Acquisition, with the
amount of such shares depending on purchase price adjustments under the
acquisition agreement and the market price of Metrocall Common Stock at the time
of the purchase. Based on second quarter results of Page America and assuming a
price of $8 per share for Metrocall Common Stock, the number of additional
shares would be approximately 782,000 shares. There can be no assurance that any
action taken by holders of these shares or other stockholders would not have an
adverse effect on the market price of the Metrocall Common Stock.
 
CONCENTRATION OF OWNERSHIP
 
     The Company's current executive officers, directors and their affiliates
together beneficially own 31.7% of the outstanding shares of Metrocall Common
Stock. In addition, immediately following the effective time of the A+ Network
Merger, executive officers, directors and affiliates of the combined entity
together will beneficially own 34.2% of the outstanding shares of Metrocall
Common Stock. As a result, such persons, if they act together, will have the
ability to substantially influence the Company's direction and to determine the
outcome of corporate actions requiring stockholder approval. This concentration
of ownership may have the effect of delaying or preventing a change of control
of the Company.
 
ANTI-TAKEOVER AND OTHER PROVISIONS
 
     The Company's Amended and Restated Certificate of Incorporation, as amended
(the "Certificate of Incorporation") and Fourth Amended and Restated Bylaws (the
"Bylaws") include provisions that could operate to delay, defer or prevent a
change of control in the event of certain transactions such as a tender offer,
merger, or sale or transfer of substantially all of the Company's assets. These
provisions are expected to discourage certain types of coercive takeover
practices and inadequate takeover bids and to encourage persons seeking to
acquire control of the Company first to negotiate with the Board of Directors of
the Company. In addition, the New Credit Facility will include, and indentures
relating to notes issued by Metrocall include, certain covenants limiting the
ability of the Company to engage in certain mergers and consolidations or
transactions involving a change of control of the Company.
 
     The Certificate of Incorporation authorizes the Board of Directors, when
considering a tender offer, merger or acquisition proposal, to take into account
factors in addition to potential economic benefits to stockholders. In addition,
the Certificate of Incorporation will generally prohibit the Company from
purchasing any shares of the Company's stock from any person, entity or group
that beneficially owns five percent or more of the Company's stock at a price
exceeding the average closing price for the 20 business days prior to the
purchase date, unless a majority of the Company's disinterested stockholders
approve the transaction, or as may be necessary to protect the Company's
regulatory licenses.
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law, as amended ("Section 203"). Under Section 203, a
resident domestic corporation may not engage in a business combination with a
person who owns (or within three years prior, did own) 15% or more of the
corporation's outstanding voting stock (an "interested stockholder") for a
period of three years after the date such person became an interested
stockholder, unless (i) prior to such date the board of directors approved
either the business combination or the transaction which resulted in the
stockholder becoming an interested stockholder, (ii) upon consummation of the
transaction which resulted in such person becoming an interested stockholder,
the interested stockholder owned at least 85% of the corporation's voting stock
outstanding at the time the transaction commenced, or (iii) on or subsequent to
such date the business combination is approved by the board of directors and
authorized by the affirmative vote of holders of at least two-thirds of the
outstanding voting stock which is not owned by the interested stockholder.

                              RECENT DEVELOPMENTS
 
RECENT AND PENDING TRANSACTIONS
 
     Reflected below is a summary of transactions by Metrocall that were
recently completed or are currently subject to binding agreements. Consummation
of pending transactions is subject to a number of conditions including, but not
limited to, receipt of all necessary regulatory approvals. In addition to the
transactions identified below, Metrocall entered into an agreement in April 1996
to purchase the assets of Source One Wireless, Inc. and placed $1 million cash
in escrow. On June 26, 1996, Metrocall advised Source One that Source One had
failed to meet certain conditions to completion of the transaction and Metrocall
terminated the agreement. On September 20, 1996, Source One filed an action in
the Circuit Court of Cook County, Illinois, claiming that Metrocall had breached
the agreement and seeking specific performance of the purchase agreement or
unspecified damages in excess of $80 million. Metrocall believes that it has
meritorious defenses to this action and intends to vigorously defend the claims
in this action.
 
  A+ Network, Inc.
 
     On May 16, 1996, Metrocall entered into an Agreement and Plan of Merger
(the "Merger Agreement") with A+ Network.
 
     Pursuant to the terms of the Merger Agreement, Metrocall purchased
2,140,526 shares of A+ Network Common Stock pursuant to a tender offer dated May
22, 1996 to the holders of such shares and Metrocall purchased 2,210,217
additional shares of A+ Network Common Stock for certain shareholders of A+
Network pursuant to a Shareholders' Option and Sale Agreement dated May 16, 1996
among Metrocall and certain shareholders of A+ Network named therein.
 
     Upon consummation of the A+ Network Merger, A+ Network will be merged with
and into Metrocall. Each share of common stock, par value $.01 per share, of A+
Network outstanding immediately prior to consummation of the Merger (other than
shares of such common stock held by Metrocall or any of its subsidiaries, which
will be canceled) will be converted into the right to receive: (i) that number
of shares of Metrocall Common Stock equal to the Conversion Ratio, (ii) the same
number of Variable Common Rights ("VCRs"), plus (iii) cash in respect of
fractional shares of Metrocall Common Stock and VCRs (together, the "Metrocall
Securities"), if any. The Conversion Ratio shall be determined by dividing
$21.10 by the average of the last bid prices for shares of Metrocall Common
Stock on the Nasdaq National Market for the 50 consecutive trading days ending
on the trading day that is five days prior to the effective time of the A+
Network Merger (the "Average Metrocall Share Price"), except that if the Average
Metrocall Share Price is greater than $21.88 or less than $17.90, then the
Conversion Ratio shall be .96435 or 1.17877, respectively. Each VCR will entitle
the holder to receive the amount, not to exceed $5.00 per VCR (unless increased
as described below), by which the market value of the Metrocall Common Stock
determined as of the first anniversary of the effective time (the "Effective
Time") of the A+ Network Merger (the "Maturity Date") is less than the "Target
Price" of $21.10 per share, adjusted downward, but not upward, based on changes
in an index composed of average closing bid prices of three other companies in
the paging industry. If Metrocall extends the Maturity Date by one year (the
"Extended Maturity Date"), the Target Price will increase to $25.10, adjusted as
previously described, and the maximum amount which the holder may receive will
be $7.00 per VCR. The market value of Metrocall Common Stock for this purpose
will be the median of the averages of the last bid price for the Metrocall
Common Stock on each trading day during each 20 trading-day period within the 60
trading days prior to the Maturity Date. In addition, if the last bid price of
the Metrocall Common Stock exceeds $21.10 on each day during any period of 50
consecutive calendar days after the Effective Time and before the Maturity Date,
or, if the Maturity Date is extended, $25.10 on each day during any period of 50
consecutive calendar days after the Maturity Date and before the Extended
Maturity Date, then the right to receive payments under the VCRs will terminate.
Any amounts payable under the VCRs will be paid in cash, Metrocall Common Stock
or shares of preferred stock of Metrocall having economic and other rights
substantially equivalent to the rights of holders of shares of Metrocall Common
Stock, as determined by Metrocall. Up to 9,042,260 shares of Metrocall Common
Stock will be issued in the
 
                                        8
<PAGE>   10
 
A+ Network Merger, and additional shares may be issued if Metrocall elects to
make any payments required under the VCRs in the form of shares of Metrocall
Common Stock.
 
     The A+ Network Merger will become effective upon the later of the
acceptance by the Secretary of State of the State of Delaware or the Secretary
of State of the State of Tennessee of filing of the Certificate of Merger, which
is expected to be executed by Metrocall and A+ Network and filed as soon as
practicable following approval of the Merger Agreement by the requisite vote of
the Metrocall stockholders and the A+ Network shareholders and satisfaction or
waiver of the other conditions set forth in the Merger Agreement. Such
conditions include (i) the absence of any statute, rule, order, decree or
regulation of a governmental entity, or injunction or other court order, that
would prohibit the consummation of the A+ Network Merger, (ii) the approval for
quotation of the shares of Metrocall Common Stock issuable pursuant to the
Merger Agreement on NNM, (iii) receipt of all authorizations, consents and
approvals necessary from the FCC and of any other governmental entity necessary
for consummation of the A+ Network Merger, (iv) the continued accuracy of the
representations and warranties made by each party in the Merger Agreement, and
(v) the absence of any material adverse change in the business, properties,
assets, liabilities, financial condition, cash flow, operations, licenses,
franchises or results of operations of either party since the date of the Merger
Agreement, with certain allowable exceptions. A special meeting of Metrocall's
stockholders to vote on the A+ Network Merger is currently scheduled to be held
on November 6, 1996.
 
     The Board of Directors of the corporation surviving the merger of Metrocall
and A+ Network (the "Surviving Corporation") will have the same membership as
the Board of Directors of Metrocall prior to the Effective Time, except that
Steven D. Jacoby and Vincent D. Kelly have both agreed to resign as directors
and Ray D. Russenberger and Elliott H. Singer will both be appointed directors.
In addition, the executive officers of Metrocall will be the executive officers
of the Surviving Corporation. Pursuant to an employment agreement, Charles A.
Emling III, currently President and Chief Executive Officer of A+ Network, has
agreed, effective as of the Effective Time, to serve as President, Southeast
Region of the Surviving Corporation for a term of one year, subject to automatic
annual extension unless either party notifies the other that the contract should
be terminated and such notice is given at least 90 days before an anniversary of
the Effective Time. Mr. Emling's employment agreement also provides for certain
severance rights.
 
     Pursuant to the terms of the Merger Agreement, the A+ Network Merger is
required to be consummated by November 16, 1996 subject to extension if final
FCC approvals have not been received by that date. If the A+ Network Merger is
not consummated or the Merger Agreement otherwise amended, the Company may be
required to sell its 40% investment in A+ Network. As of June 30, 1996, the
Company's investment in A+ Network together with related goodwill is reflected
on the Company's balance sheet at approximately $92 million, which resulted from
a cash purchase price of $21.10 per share for approximately 4.4 million shares
of A+ Network. The closing market price of A+ Network common stock on September
27, 1996 was $7.75 per share, or a decrease, based upon market value, of
approximately $58 million. Therefore, if the Company were required to sell this
investment at current market prices, the Company would likely realize a
substantial loss upon disposition, which has not been reflected in the pro forma
statement incorporated herein.
 
  Parkway Paging, Inc.
 
     On July 16, 1996, Metrocall completed the acquisition of Parkway Paging,
Inc. of Plano, Texas ("Parkway"). Metrocall paid $25 million in cash and assumed
approximately $3.2 million in long-term obligations at closing to complete the
acquisition. The Company also incurred direct acquisition costs of $600,000.
 
  Satellite Paging and Message Network
 
     On August 30, 1996, Metrocall completed the acquisition of Satellite Paging
of Fairfield, New Jersey and Message Network of Boca Raton, Florida. Metrocall
paid $17 million in cash and issued 1,417,181 of the Shares subject to this
Registration Statement to complete the acquisition. The number of shares issued
at closing will be adjusted if necessary so that the aggregate value of the
shares issued will be $10,008,843 based upon the average of the midpoints of the
closing bid and asked prices of Common Stock for the five trading day period
ending on the second business day prior to (a) the effective date of the
Registration Statement in the case of shares not held in escrow and (b) the date
of release from escrow for shares held in
 
                                        9
<PAGE>   11
 
escrow. Additional shares of Common Stock may also be issued as an adjustment to
the purchase price based on certain defined performance criteria.
 
  Page America Group, Inc.
 
     On April 22, 1996, Metrocall signed a definitive acquisition agreement (the
"Page America Agreement") with Page America Group, Inc. of Hackensack, New
Jersey ("Page America"). Under the terms of the Page America Agreement,
Metrocall will acquire substantially all of the assets of Page America in
exchange for $55 million in cash and up to 1.3 million shares of Metrocall
Common Stock, subject to adjustment. Pursuant to the terms of the New Credit
Facility, Metrocall is required to complete the A+ Network Merger and raise $25
million in new equity financing before completing the acquisition of Page
America.
 
NEW CREDIT FACILITY
 
     On September 20, 1996, Metrocall entered into an agreement with The
Toronto-Dominion Bank and The First National Bank of Boston to amend and restate
the loan agreement governing Metrocall's existing credit facility. Subject to
certain conditions set forth in the new agreement, Metrocall may borrow up to
$350,000,000 under two loan facilities. The first facility ("Facility A") is a
$225,000,000 reducing revolving credit facility and the second ("Facility B") is
a $125,000,000 reducing credit facility (together Facility A and Facility B are
referred to as the "New Credit Facility"). Up to $100,000,000 under Facility A
is currently available for borrowing; the remaining $125,000,000 commitment
under Facility A and all of the Facility B commitment will become available only
after completion of the A+ Network Merger (the "Merger Condition") and the
infusion of $25,000,000 of equity (net of reasonable transaction costs) into
Metrocall (the "Equity Condition"). Amounts borrowed under Facility B may only
be used to refinance the 11 7/8% Senior Subordinated Notes due 2005 of A+
Network. If the Merger Condition and Equity Condition have not been completed on
or prior to December 16, 1996, the remaining $125,000,000 commitment under
Facility A and the commitment under Facility B will terminate automatically. The
New Credit Facility has a term of eight years and is secured by substantially
all the assets of Metrocall. Required quarterly principal repayments begin on
March 31, 2000 and continue through December 31, 2004.
 
     The New Credit Facility contains various covenants that, among other
restrictions, require Metrocall to maintain certain financial ratios, including
total debt to annualized operating cash flow (not to exceed 6.6 to 1.0 through
September 30, 1996 and declining thereafter), senior debt to annualized
operating cash flow, annualized operating cash flow to pro forma debt service,
total sources of cash to total uses of cash and operating cash flow to interest
expense (in each case, as such terms are defined in the agreement relating to
the New Credit Facility). As a result, as of October 1, 1996, Metrocall is not
entitled to draw any of the $33 million remaining available under Facility A.
The New Credit Facility also requires Metrocall to raise at least $50 million in
new equity if its ratio of cash flow to interest expense is less than 2.0 to 1
for the quarter ended June 30, 1997. The covenants also limit additional
indebtedness and future mergers and acquisitions (other than the A+ Network
Merger and the acquisition of Page America) without the approval of the lenders
and restrict the payment of cash dividends and other stockholder distributions
by Metrocall during the term of the New Credit Facility. The New Credit Facility
also prohibits certain changes in ownership control of Metrocall, as defined,
during the term of the New Credit Facility.
 
     Under the New Credit Facility, Metrocall may designate all or any portion
of the borrowings outstanding as either a floating base rate advance or a
Eurodollar rate advance with an applicable margin that ranges from 0.0% to
1.750% for base rate advances and 0.75% to 2.750% for Eurodollar rate advances.
The predefined margins will be based upon the level of indebtedness outstanding
relative to annualized cash flow, as defined in the agreement relating to the
New Credit Facility. As of September 27, 1996, the interest rate on base rate
advances was 10.0% and no Eurodollar rate advances were outstanding. Commitment
fees of 0.25% to 0.375% per year (depending on the level of Metrocall's
indebtedness outstanding to annualized cash flow) will be charged on the average
unused balance and will be charged to interest expense as incurred. Under the
New Credit Facility, Metrocall must obtain and maintain interest rate protection
on at least 50% of Metrocall's outstanding debt; all fixed rate debt, including
the 10 3/8% Senior Subordinated Notes due 2007, will count against the
requirement.

     Certain stockholders of Metrocall holding approximately 40.3% of the issued
and outstanding shares of Metrocall Common Stock (prior to the A+ Network
Merger) are parties to a voting agreement (the "Voting Agreement") pursuant to
which the stockholders agreed to vote for up to seven persons designated by
various of the stockholders to serve as directors of Metrocall. In connection
with the adoption of the Merger Agreement, these stockholders have agreed to
amend the Voting Agreement to provide for its termination effective as of the
Effective Time of the A+ Network Merger, but have agreed to vote in favor of the
reelection of Ms. Brock when her term expires at the next Metrocall annual
meeting and in favor of the election of Messrs. Singer and Russenberger to fill
the vacancies created by the resignations of Messrs. Jacoby and Kelly. Messrs.
Singer and Russenberger have separately agreed to vote shares of Metrocall
Common Stock they hold at the next Metrocall annual meeting in favor of the
reelection of Ms. Brock.
 
     Mr. Collins, Mr. Jacoby, and Mr. Kelly entered into new employment
contracts approved by the Compensation Committee and dated May 15, 1996. The new
contracts did not change the salary or benefits of any of those officers, except
that Metrocall will now be responsible for certain life insurance premiums
incurred by Mr. Collins. The term of employment for each of the officers was
extended to December 31, 1999 from December 31, 1996 (for Mr. Collins), August
31, 1998 (for Mr. Jacoby), and June 1, 1999 (for Mr. Kelly). In addition, Mr.
Collins' contract now includes a provision (similar to that in Messrs. Jacoby's
and Kelly's contracts) for automatic one-year extensions on anniversaries of May
15.
 
     Each of Messrs. Collins', Jacoby's and Kelly's contracts provides that, if
the executive's employment is terminated without cause, if the executive
terminates the contract for good reason, or if the executive's employment is
terminated by reason of death or disability, Metrocall will pay the executive or
his estate the full base salary and benefits (in connection with termination
without cause or resignation for good reason) that would otherwise have been
paid to the executive during the remaining term of the agreement. Terminations
without cause or resignations for good reason would also require Metrocall to
pay the executive, at his election,
 
                                       12
<PAGE>   14
 
the difference between the fair market value of stock subject to options
(including those otherwise unexercisable) and the price he would have had to pay
to exercise the options. If the executive voluntarily terminates employment
(other than for good reason), Metrocall will pay the executive one year's base
salary and benefits under the contract. The reasons for resignation for good
reason under the revised contracts include the termination of any of the others
for reasons other than cause, death, or disability.
 
     Messrs. Collins, Jacoby, and Kelly entered into separate change of control
agreements approved by the Compensation Committee as of May 15, 1996 to run
through December 31, 1999 (with automatic extensions). Changes of control are
defined as: (i) any action required to be reported pursuant to Item 6(e) of
Schedule 14A as a "change of control" (generally a 50% change in share ownership
but other changes may also qualify), (ii) any person's acquiring more than 25%
of the voting power of Metrocall voting stock, unless with the prior approval of
the Board, (iii) changes in Board membership such that during any two
consecutive years, Board members at the beginning constitute less than a
majority of the Board at the end (including as Board members at the beginning of
the period any directors added during the period with approval of two-thirds of
the Board), (iv) a merger or reorganization in which Metrocall does not survive
or in which the outstanding shares of Metrocall are converted into other shares
or securities (except through a reincorporation or setting up a holding
company); (v) a more than 50% turnover of voting power in a merger,
reorganization, or other similar transaction approved by stockholders, unless
75% of the Board carries over to the new entity; or (vi) any other event the
Board determines constitutes a change of control. A change of control is also
deemed to occur if the executive is removed at the request of a third party who
has taken steps to effect a change of control or the termination was otherwise
caused by a change of control. Under the change of control agreements,
executives would be entitled to payment of three times the sum of their salary
and most recent bonus within 30 days after termination of employment after a
change of control (other than termination for death, disability, or cause),
together with a payment of the option spread (as described above under
terminations of employment), paid health coverage for up to 18 months, and
certain other benefits. Payments would be grossed up, as necessary, to provide
that the executive receives his payments net of any excise taxes and any taxes
on the excise payment (but the executive would remain responsible for any income
taxes on the payment).
 
     Messrs. Collins, Jacoby and Kelly hold options to acquire 100,000, 100,000
and 206,588 shares of Metrocall Common Stock, respectively. On September 18,
1996, the Compensation Committee of the Metrocall Board of Directors changed the
exercise price of all non-qualified options outstanding to all current employees
of Metrocall as of that date to equal $7.9375 per share, the closing price of
Metrocall Common Stock on that date. Prior to this action: Mr. Collins' options
were exercisable until January 16, 2006 for a price of $19.125; Mr. Jacoby's
options were exercisable until July 26, 2005 for a price of $20.25 (50,000
shares), until January 16, 2006 for a price of $19.125 (25,000 shares) and until
February 7, 2006 for a price of $20.25 (25,000 shares); and Mr. Kelly's options
were exercisable until November 8, 2003 for a price of $19.50 (72,000 shares),
until May 23, 2004 for a price of $13.00 (34,588 shares), until July 26, 2005
for a price of $20.25 (50,000 shares), until January 16, 2006 for a price of
$19.125 (25,000 shares) and until February 7, 2006 for a price of $20.25 (25,000
shares).

     The Company will not receive any of the proceeds from the sale of the
Shares by the Selling Stockholder.
 
                              SELLING STOCKHOLDER
 
     The following table sets forth certain information regarding beneficial
ownership of the Shares as of September 26, 1996 and the number of Shares which
may be offered for the account of the Selling Stockholder or its transferees or
distributees from time to time. Because the Selling Stockholder may sell all or
any part of its Shares pursuant to this Prospectus, no estimate can be given as
to the number of Shares that will be held by the Selling Stockholder upon
termination of this offering. The amounts set forth below are to the best of the
Company's knowledge. See "Plan of Distribution."

(1) Includes 136,833 shares which may be issued depending upon certain purchase
    price adjustments and the market price of the Common Stock on the second
    business day prior to the effectiveness of this Registration Statement.
(2) Includes an aggregate of 212,389 Shares which are held in escrow pursuant to
    the terms of an Amended and Restated Escrow Agreement dated as of       ,
    1996, among Metrocall, the Selling Stockholder and certain other parties
    (the "Escrow Agreement"). Such Shares may not be released from escrow and
    sold hereunder except in compliance with all terms and conditions of the
    Escrow Agreement.
 
                              PLAN OF DISTRIBUTION
 
     The Shares offered hereby may be sold by the Selling Stockholder or by its
pledgees, donees, transferees or other successors in interest. Such sales may be
made at fixed prices that may be changed, at market prices prevailing at the
time of sale, at prices related to such prevailing market prices, or at
negotiated prices. The Shares may be sold by one or more of the following: (a)
one or more block trades in which a broker or dealer so engaged will attempt to
sell all or a portion of the Shares held by the Selling Stockholder as agent but
may position and resell a portion of the block as principal to facilitate the
transaction; (b) purchase by a broker or dealer as principal and resale by such
broker or dealer for its account pursuant to this Prospectus; (c) ordinary
brokerage transactions and transactions in which the broker solicits purchasers;
and (d) face-to-face transactions between the Selling Stockholder and purchasers
without a broker-dealer. The Selling Stockholder may effect such transactions by
selling shares to or through broker-dealers, and such broker-dealers will
receive compensation in negotiated amounts in the form of discounts,
concessions, commissions or fees from the Selling Stockholder and/or the
purchasers of the shares for whom such broker-dealers may act as agent or to
whom they sell as principal, or both (which compensation to a particular
broker-dealer might be in excess of customary commissions). Such brokers or
dealers or other participating brokers or dealers and the Selling Stockholder
may be deemed to be "underwriters" within the meaning of the Securities Act of
1933, in connection with such sales. In addition, any securities covered by this
Prospectus that qualify for sale pursuant to Rule 144 might be sold under Rule
144 rather than pursuant to this Prospectus.
 
     The Asset Purchase Agreement dated as of February 28, 1996, as amended on
August 30, 1996 (the "Asset Purchase Agreement"), by and among Satellite and
Message Network (collectively, the "Seller"), Bertram M. Wachtel, Edward R.
Davalos and Kevan D. Bloomgren (collectively, the "Stockholders" and
individually, a "Stockholder"), and Metrocall provides that for a period of two
years from the closing under the Asset Purchase Agreement (the "Closing"), no
Seller or Stockholder may sell, assign, transfer, pledge or otherwise dispose of
any Shares unless such Seller or Stockholder shall first have offered to sell
such Shares to Metrocall. Upon such an offer, Metrocall has the right to
purchase all, but not less than all, of the Shares subject to such offer for a
price per share equal to the opening ask price on the date of the sale less 3%.
In addition, the Asset Purchase Agreement provides that for a period of six
months from the Closing, Metrocall or its designee shall have the option to
purchase any Shares held by a seller or stockholder and not offered for sale as
described in the immediately preceding sentences for a price equal to the
greater of (i) the Issue Price (as defined below) or (ii) the opening ask price
immediately following the delivery of notice of the exercise of
 
                                       14
<PAGE>   16
 
this option less 3%. The "Issue Price" is equal to the average of the midpoints
of the closing bid and ask prices of Metrocall Common Stock for the five trading
day period ending on the second business day prior to the effective date of this
Registration Statement.
 
     This Registration Statement shall remain effective until all Shares could
immediately be sold pursuant to Rule 144 and Rule 145(d) under the Securities
Act of 1933 without regard to the volume limitations.
 
                                 LEGAL MATTERS
 
     The issuance of the Shares will be passed upon for the Company by Wilmer,

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporate Law ("DGCL") empowers a
Delaware corporation to indemnify any person who was or is, or is threatened to
be made, a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
an action by or in the right of such corporation) by reason of the fact that
such person is or was a director, officer, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise. The indemnity may include expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such action,
suit or proceeding, provided that such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, such person had no reasonable cause to believe his conduct was
unlawful. A Delaware corporation may indemnify such persons against expenses
(including attorneys' fees) in actions brought by or in the right of the
corporation to procure a judgment in its favor under the same conditions, except
that no indemnification is permitted in respect of any claim, issue or matter as
to which such person shall have been adjudged to be liable to the corporation
unless and to the extent the Court of Chancery of the State of Delaware or the
court in which such action or suit was brought shall determine upon application
that, in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses as the Court of Chancery or
other such court shall deem proper. To the extent such person has been
successful on the merits or otherwise in defense of any action referred to
above, or in defense of any claim, issue or matter therein, the corporation must
indemnify such person against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection therewith. The indemnification
and advancement of expenses provided for in, or granted pursuant to, Section 145
is not exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors or otherwise.
 
     Section 145 also provides that a corporation may maintain insurance against
liabilities for which indemnification is not expressly provided by the statute.
 
     Section 6 of the Metrocall Amended and Restated Certificate of
Incorporation provides for indemnification of the directors, officers, employees
and agents of Metrocall to the full extent currently permitted by the DGCL.
 
     In addition, the Metrocall Amended and Restated Certificate of
Incorporation, as permitted by Section 102(b) of the DGCL, limits directors'
liability to Metrocall and its stockholders by eliminating liability in damages
for breach of fiduciary duty. Section 5.5 of the Metrocall Amended and Restated
Certificate of Incorporation provides that neither Metrocall nor its
stockholders may recover damages from Metrocall directors for breach of their
fiduciary duties in the performance of their duties as directors of
 
                                      II-1
<PAGE>   19
 
Metrocall. As limited by Section 102(b), this provision cannot, however, have
the effect of indemnifying any director of Metrocall in the case of liability
(i) for a breach of the director's duty of loyalty, (ii) for acts of omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) for unlawful payments of dividends or unlawful stock repurchases
or redemptions as provided in Section 174 of the DGCL or (iv) for any
transactions for which the director derived an improper personal benefit.

                     dollar value of securities offered would not exceed that
                     which was registered) and any deviation from the low or
                     high and of the estimated maximum offering range may be
                     reflected in the form of prospectus filed with the
                     Commission pursuant to Rule 424(b) if, in the aggregate,
                     the changes in volume and price represent no more than 20
                     percent change in the maximum aggregate offering price set
                     forth in the "Calculation of Registration Fee" table in the
                     effective registration statement;
 
               (iii) To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     registration statement or any material change to such
                     information in the registration statement;
 
        provided, however, that paragraphs (c)(1)(i) and (c)(1)(ii) do not apply
        if the information required to be included in a post-effective amendment
        by those paragraphs is contained in periodic reports filed with or
        furnished to the Commission by the registrant pursuant to Section 13 or
        15(d) of the Securities Exchange Act of 1934 that are incorporated by
        reference in the registration statement.
 
        (2) That, for the purpose of determining any liability under the
            Securities Act of 1933, each such post-effective amendment shall be
            deemed to be a new registration statement relating to the securities
            offered therein, and the offering of such securities at that time
            shall be deemed to be the initial bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
            any of the securities being registered which remain unsold at the
            termination of the offering.

                  (a) Choice of Interest Rate, Etc. Any Advance shall, at the
option of the Borrower, be made as a Base Rate Advance or a Eurodollar Advance;
provided, however, that at such time as there shall have occurred and be
continuing a Default hereunder, the Borrower shall not have the right to receive
a Eurodollar Advance. Any notice given to the Administrative Agent in connection
with a requested Advance hereunder shall be given to the Administrative Agent
prior to 11:00 a.m. (New York time) in order for such Business Day to count
toward the minimum number of Business Days required.

                  (b) Base Rate Advances.

                      (i)  Advances. The Borrower shall give the Administrative
         Agent irrevocable prior written notice prior to 11:00 a.m. (New York
         time) on the date of any requested Base Rate Advance in the form of a
         Request for Advance, or telephonic notice followed immediately by a
         Request for Advance; provided, however, that the Borrower's failure to
         confirm any telephonic notice with a Request for Advance shall not
         invalidate any notice so given if acted upon by the Administrative
         Agent. Upon receipt of such notice from the Borrower, the
         Administrative Agent shall promptly notify each Bank by telephone or
         telecopy of the contents thereof.

                      (ii) Repayments and Reborrowings. The Borrower may repay
         or prepay a Base Rate Advance without regard to its Payment Date and
         (A) upon irrevocable prior written notice prior to 11:00 a.m. (New York
         time) on the date of any requested repayment and reborrowing, reborrow
         all or a portion of the principal amount thereof as a Base Rate
         Advance, (B) upon at least three (3) Business Days' irrevocable prior
         written notice, reborrow all or a portion of the principal thereof as
         one or more Eurodollar Advances, or (C) not reborrow all or any portion
         of such Base Rate Advance. On the date indicated by the Borrower, such
         Base Rate Advance shall be so repaid and, as applicable, reborrowed.
         The failure to give timely notice hereunder with respect to the Payment
         Date of any Base Rate Advance shall be deemed a request for a Base Rate
         Advance.

                  (c) Eurodollar Advances.

                      (i)  Advances. Upon request, the Administrative Agent,
         whose determination shall be conclusive, shall determine the available
         Eurodollar Bases and shall notify the Borrower of such Eurodollar
         Bases. The Borrower shall give the Administrative Agent in the case of
         Eurodollar Advances at least three (3) Business Days' irrevocable prior


                                      -26-
<PAGE>   32
         written notice in the form of a Request for Advance, or telephonic
         notice followed immediately by a Request for Advance; provided,
         however, that the Borrower's failure to confirm any telephonic notice
         with a Request for Advance shall not invalidate any notice so given if
         acted upon by the Administrative Agent. Upon receipt of such notice
         from the Borrower, the Administrative Agent shall promptly notify each
         Bank by telephone or telecopy of the contents thereof.

                      (ii) Repayments and Reborrowings. At least three (3)
         Business Days prior to the Payment Date for each Eurodollar Advance,
         the Borrower shall give the Administrative Agent written notice
         specifying whether all or a portion of such Eurodollar Advance (A) is
         to be repaid and then reborrowed in whole or in part as one or more
         Eurodollar Advances, (B) is to be repaid and then reborrowed in whole
         or in part as a Base Rate Advance, or (C) is to be repaid and not
         reborrowed. The failure to give such notice shall preclude the Borrower
         from reborrowing such Advance as a Eurodollar Advance on its Payment
         Date and shall be deemed a request for a Base Rate Advance. Upon such
         Payment Date such Eurodollar Advance will, subject to the provisions
         hereof, be so repaid and, as applicable, reborrowed.

                  (d) Notification of Banks. Upon receipt of a Request for
Advance, or a notice from the Borrower with respect to any outstanding Advance
prior to the Payment Date for such Advance, the Administrative Agent shall
promptly notify each Bank by telephone or telecopy of the contents thereof and
the amount of such Bank's portion of the Advance. Each Bank shall, not later
than 12:00 noon (New York time) on the date of borrowing specified in such
notice, make available to the Administrative Agent at the Administrative Agent's
Office, or at such account as the Administrative Agent shall designate, the
amount of its portion of any Advance which represents an additional borrowing
hereunder in immediately available funds.

                  (e) Disbursement.

                      (i) Prior to 2:00 p.m. (New York time) on the date of an
         Advance hereunder, the Administrative Agent shall, subject to the
         satisfaction of the conditions set forth in Article 3 hereof, disburse
         the amounts made available to the Administrative Agent by the Banks in
         like funds by (a) transferring the amounts so made available by wire
         transfer pursuant to the Borrower's instructions, or (b) in the absence
         of such instructions, crediting the amounts so made available to the
         account of the Borrower maintained with the Administrative Agent.



                                      -27-
<PAGE>   33
                        (ii) Unless the Administrative Agent shall have received
         notice from a Bank prior to 12:00 noon (New York time) on the date of
         any Advance that such Bank will not make available to the
         Administrative Agent such Bank's ratable portion of such Advance, the
         Administrative Agent may assume that such Bank has made or will make
         such portion available to the Administrative Agent on the date of such
         Advance and the Administrative Agent may in its sole discretion and in
         reliance upon such assumption, make available to the Borrower on such
         date a corresponding amount. If and to the extent the Bank does not
         make such ratable portion available to the Administrative Agent, such
         Bank agrees to repay to the Administrative Agent on demand such
         corresponding amount together with interest thereon, for each day from
         the date such amount is made available to the Borrower until the date
         such amount is repaid to the Administrative Agent, at the Federal Funds
         Rate.

                       (iii) If such Bank shall repay to the Administrative
         Agent such corresponding amount, such amount so repaid shall constitute
         such Bank's portion of the applicable Advance for purposes of this
         Agreement. If such Bank does not repay such corresponding amount
         immediately upon the Administrative Agent's demand therefor, the
         Administrative Agent shall notify the Borrower and the Borrower shall
         immediately pay such corresponding amount to the Administrative Agent,
         with interest at the Federal Funds Rate. The failure of any Bank to
         fund its portion of any Advance shall not relieve any other Bank of its
         obligation, if any, hereunder to fund its respective portion of the
         Advance on the date of such borrowing, but no Bank shall be responsible
         for any such failure of any other Bank.

                        (iv) In the event that, at any time when the Borrower is
         not in Default and has otherwise satisfied each of the conditions in
         Section 3.2 hereof, a Bank for any reason fails or refuses to fund its
         portion of such Advance, then, until such time as such Bank has funded
         its portion of such Advance (which late funding shall not absolve such
         Bank from any liability it may have to the Borrower), or all other
         Banks have received payment in full from the Borrower (whether by
         repayment or prepayment) or otherwise of the principal and interest due
         in respect of such Advance, such non-funding Bank shall not have the
         right (A) to vote regarding any issue on which voting is required or
         advisable under this Agreement or any other Loan Document, and such
         Bank's portion of the Loans shall not be counted as outstanding for
         purposes of determining "Majority Banks" hereunder, or (B) to receive
         payments of principal, interest or fees from the Borrower, the
         Administrative Agent or the other Banks in respect of its portion of
         the Loans.

         Section 2.3                Interest.

                  (a) On Base Rate Advances. Interest on each Base Rate Advance
shall be computed on the basis of a year of 365/366 days for the actual number
of days elapsed and shall be payable at the Base Rate Basis for such Advance, in

outstanding shall also be due and payable on the Maturity Date.

Advance shall be computed on the basis of a 360-day year for the actual number

in arrears on the applicable Payment Date, and, in addition, if the Interest
Period for a Eurodollar Advance exceeds three (3) months, interest on such
Eurodollar Advance shall also be due and payable in arrears on every three-month
anniversary of the beginning of such Interest Period. Interest on Eurodollar
Advances then outstanding shall also be due and payable on the Maturity Date.

                  (c) Interest if no Notice of Selection of Interest Rate Basis.
If the Borrower fails to give the Administrative Agent timely notice of its
selection of a Eurodollar Basis, or if for any reason a determination of a
Eurodollar Basis for any Advance is not timely concluded, the Base Rate Basis
shall apply to such Advance.

                  (d) Interest Upon Default. Immediately upon the occurrence of
an Event of Default hereunder, the outstanding Obligations (to the extent
permitted by Applicable Law) shall bear interest at the Default Rate. Such
interest shall be payable on demand by the Majority Banks and shall accrue until
the earlier of (i) waiver or cure of the applicable Event of Default, (ii)
agreement by the Majority Banks (or, if applicable to the underlying Event of

                           Notwithstanding the foregoing, if the Borrower
shall fail timely to deliver the Administrative Agent the financial statements
required for the calculation of the Total Leverage Ratio for any fiscal quarter,
then commencing with the fifth (5th) Business Day after the date such financial
statements were due and continuing through the fifth (5th) Business Day
following the date of delivery thereof, the Total Leverage Ratio for such period
shall be conclusively presumed to be, and the Applicable Margin shall be
calculated based upon, the Total Leverage Ratio which is one level greater than
the Total Leverage Ratio in effect for the immediately preceding fiscal quarter
for which financial statements were delivered or were due to be delivered,
provided that such Total Leverage Ratio for any such period shall be
recalculated upon delivery to the Administrative Agent of the delinquent
financial statements and an appropriate adjustment shall be made by the
Administrative Agent to the Applicable Margin, based upon the Total Leverage
Ratio reflected

in the delinquent financial statements, retroactive to the first day for which
the presumed Total Leverage Ratio was applied.

         Section 2.4  Commitment Fees.

                  (a) The Borrower agrees to pay each of the Banks, in
accordance with their respective Commitment Ratios, a commitment fee on the
aggregate unborrowed balance of the available Facility A Commitment plus the
aggregate unborrowed balance of the available Facility B Commitment, for each
day from the Agreement Date until the Maturity Date, (i) at all times during
which the Total Leverage Ratio is greater than or equal to 4.50:1, at the rate
of three-eighths of one percent (3/8%) per annum, and (ii) at all times during
which the Total Leverage Ratio is less than 4.50:1, at the rate of one-quarter
of one percent (1/4%) per annum.

                  (b) The Borrower further agrees to pay each of the Banks, in
accordance with their respective Commitment Ratios, a commitment fee on the
Unavailable Portions of the Commitments for each day from the Agreement Date
until the earlier of (i) the A+ Merger Events Completion Date or (ii) December
16, 1996, at the rate of one-quarter of one percent (1/4%) per annum.

                  (c) Such commitment fees shall be computed on the basis of a
year of 365/366 days for the actual number of days elapsed, shall be payable
quarterly in arrears on the last day of each calendar quarter, and shall be
fully earned when due and non-refundable when paid. A final payment of all
commitment fees then payable shall also be due and payable on the Maturity Date.

         Section 2.5  Mandatory Commitment Reductions.

                  (a) Scheduled Reductions in Facility A Commitment. Commencing

                  (b) Excess Cash Flow Recapture. Commencing on March 31, 2000
and on each March 31st and September 30th occurring thereafter during the term
of this Agreement, the Facility A Commitment shall be automatically and
permanently reduced by an amount equal to fifty percent (50%) of Excess Cash
Flow, determined for the two (2) consecutive fiscal quarters then ended.

                  (c) Reductions in Facility B Commitment from Subordinated Debt
Proceeds. The Facility B Commitment shall be automatically and permanently
reduced in an amount equal to the aggregate amount of any Subordinated Debt (net
of reasonable and customary transaction costs) issued by the Borrower or any of
its Restricted Subsidiaries on or after the Agreement Date immediately upon the
issuance thereof.

The Borrower shall make a repayment of the Loans outstanding under the
applicable Commitment, together with accrued interest thereon, on or before the
effective date of each reduction in such Commitment under this Section 2.5, such
that the aggregate principal amount of the Loans outstanding under such
Commitment at no time exceeds such Commitment as so reduced. Any remaining
unpaid principal and interest under the Commitments shall be due and payable in
full on the Maturity Date, and the Commitments shall thereupon terminate to the
extent not previously terminated.

         Section 2.6 Voluntary Commitment Reductions. The Borrower shall have
the right, at any time and from time to time after the Agreement Date, upon at
least three (3) Business Days' prior written notice to the Administrative Agent,
without premium or penalty, to cancel or reduce permanently all or a portion of
either Commitment, on a pro rata basis among the Banks; provided, however, that
any such partial reduction shall be made in an amount not less than $5,000,000
and in integral multiples of $1,000,000. As of the date of cancellation or
reduction set forth in such notice, the applicable Commitment shall be
permanently reduced to the amount stated in the Borrower's notice for all
purposes herein, and the Borrower shall pay to the Administrative Agent for the
Banks the amount necessary to reduce the principal amount of the Loans then
outstanding under such Commitment to not more than the amount of such Commitment
as so reduced, together with accrued interest on the amount so prepaid


                                      -32-

and commitment fees accrued through the date of the reduction with respect to
the amount reduced.

         Section 2.7 Prepayments and Repayments.

                  (a) Prepayment. The principal amount of any Base Rate Advance
may be prepaid in full or ratably in part at any time, without penalty and
without regard to the Payment Date for such Advance. Eurodollar Advances may be
prepaid prior to the applicable Payment Date, upon three (3) Business Days'
prior written notice to the Administrative Agent, provided that the Borrower
shall reimburse the Banks and the Administrative Agent, on the earlier of demand
by the applicable Bank or the Maturity Date, for any loss or out-of-pocket
expense incurred by any Bank or the Administrative Agent in connection with such
prepayment, as set forth in Section 2.10 hereof. Any prepayment hereunder shall
be in amounts of not less than $1,000,000 and in integral multiples thereof.
Amounts prepaid pursuant to this Section may be reborrowed, subject to the terms
and conditions hereof. Prepayments of Advances under the Facility B Commitment
after the Facility B Commitment Termination Date shall be applied to amounts
outstanding thereunder in inverse order of maturity. Amounts prepaid pursuant to
this Section may be reborrowed, subject to the terms and conditions hereof.

                  (b)   Repayments.

                        (i) Loans in Excess of Commitments. If, at any time, the
         amount of the Loans then outstanding under either Commitment shall
         exceed the applicable Commitment, the Borrower shall, on such date and
         subject to Section 2.10 hereof, make a repayment of the principal
         amount of the Loans in an amount equal to such excess, together with
         any accrued interest and fees with respect thereto.

                        (ii) Scheduled Repayments under Facility B Commitment.
         Commencing March 31, 2000, the principal balance then outstanding under
         the Facility B Commitment shall be amortized in quarterly installments
         equal to the percentage of such principal balance set forth below on
         the dates set forth below:

                       (iii) Equity Proceeds. The Borrower shall repay Loans
         outstanding under the Facility A Commitment with the proceeds of any
         equity issued by the Borrower on or after the Agreement Date, net of
         reasonable and customary transaction costs.

                        (iv) Asset Sale Proceeds. The Borrower shall repay the
         Loans outstanding under the Commitments as set forth in Section 7.4(a)
         hereof. On and after the Facility B Commitment Termination Date any
         such payments in respect of the Facility B Commitment shall be applied
         to Loans outstanding thereunder in inverse order of maturity.

                         (v) Maturity Date. In addition to the foregoing, a
         final payment of all Obligations then outstanding shall be due and
         payable on the Maturity Date.

         Section 2.8  Notes; Loan Accounts.

                  (a) The Loans shall be repayable in accordance with the terms
and provisions set forth herein and shall be evidenced by the Notes. One
Facility A Note and one Facility B Note shall be payable to the order of each
Bank, in accordance with such Bank's respective Commitment Ratio. The Notes
shall be issued by the Borrower to the Banks and shall be duly executed and
delivered by one or more Authorized Signatories.

                  (b) Each Bank may open and maintain on its books in the name
of the Borrower a loan account with respect to its portion of the Loans and
interest thereon. Each Bank which opens such a loan account shall debit such
loan account for the principal amount of its portion of each Advance made by it
and accrued interest thereon, and shall credit such loan account for each
payment on account of principal of or interest on its Loans. The records of a
Bank with respect to the loan account maintained by it shall be prima facie
evidence of its portion of the Loans and accrued interest thereon absent
manifest error, but the failure of any Bank to make any such notations or any
error or mistake in such notations shall not affect the Borrower's repayment
obligations with respect to such Loans.

         Section 2.9                Manner of Payment.

                  (a) Each payment (including any prepayment) by the Borrower on
account of the principal of or interest on the Loans, commitment fees and any
other amount owed to the Banks or the Administrative Agent or any of them under
this Agreement or the Notes shall be made not later than 1:00 p.m. (New York
time) on the date specified for payment under this Agreement to the
Administrative Agent at the Administrative Agent's Office, for the account of
the Banks or the Administrative Agent, as the case may be, in lawful money of
the United States of America in immediately available funds. Any payment
received by the Administrative Agent after 1:00 p.m. (New York time) shall be
deemed received on the next Business Day. Receipt by the Administrative Agent of
any payment intended for any Bank or Banks hereunder prior to 1:00 p.m. (New
York time) on any Business Day shall be deemed to constitute receipt by such
Bank or Banks on such Business Day. In the case of a payment for the account of
a Bank, the Administrative Agent will promptly thereafter distribute the amount
so received in like funds to such Bank. If the Administrative Agent shall not
have received any payment from the Borrower as and when due, the Administrative
Agent will promptly notify the Banks accordingly. In the event that the
Administrative Agent shall fail to make distribution to any Bank as required
under this Section 2.9, the Administrative Agent agrees to pay such Bank
interest from the date such payment was due until paid at the Federal Funds
Rate.

                  (b) The Borrower agrees to pay principal, interest, fees and
all other amounts due hereunder or under the Notes without set-off or
counterclaim or any deduction whatsoever and free and clear of all taxes, levies
and withholding. If the Borrower is required by Applicable Law to deduct any
taxes from or in respect of any sum payable to the Administrative Agent or any
Bank hereunder, under any Note or under any other Loan Document: (i) the sum
payable hereunder or thereunder, as applicable, shall be increased to the extent
necessary to provide that, after making all required deductions (including
deductions applicable to additional sums payable under this Section 2.9(b)), the
Administrative Agent or such Bank, as applicable, receives an amount equal to
the sum it would have received had no such deductions been made; (ii) the
Borrower shall make such deductions from such sums payable hereunder or
thereunder, as applicable, and pay the amount so deducted to the relevant taxing
authority as required by Applicable Law; and (iii) the Borrower shall provide
the Administrative Agent or such Bank, as applicable, with evidence satisfactory
to the Administrative Agent or such Bank, as applicable, that such deducted
amounts have been paid to the relevant taxing authority.

<PAGE>   41
                  (c) Prior to the declaration of an Event of Default under
Section 8.2 hereof, if some but less than all amounts due from the Borrower are
received by the Administrative Agent with respect to the Obligations, the
Administrative Agent shall distribute such amounts in the following order of
priority, all on a pro rata basis to the Banks: (i) to the payment on a pro rata
basis of any fees or expenses then due and payable to the Administrative Agent
and the Banks, or any of them; (ii) to the payment of interest then due and
payable on the Loans; (iii) to the payment of all other amounts not otherwise
referred to in this Section 2.9(c) then due and payable to the Administrative
Agent and the Banks, or any of them, hereunder or under the Notes or any other
Loan Document; and (iv) to the payment of principal then due and payable on the
Loans.

                  (d) Subject to any contrary provisions in the definition of
Interest Period, if any payment under this Agreement or any of the other Loan
Documents is specified to be made on a day which is not a Business Day, it shall
be made on the next Business Day, and such extension of time shall in such case
be included in computing interest and fees, if any, in connection with such
payment.

         Section 2.10               Reimbursement.

                  (a) Whenever any Bank shall sustain or incur any losses or
out-of-pocket expenses in connection with (i) failure by the Borrower to borrow
any Eurodollar Advance after having given notice of its intention to borrow in
accordance with Section 2.2 hereof (whether by reason of the Borrower's election
not to proceed or the non-fulfillment of any of the conditions set forth in
Article 3), or (ii) prepayment (or failure to prepay after giving notice
thereof) of any Eurodollar Advance in whole or in part for any reason, the
Borrower agrees to pay to such Bank, upon the earlier of such Bank's demand or
the Maturity Date, an amount sufficient to compensate such Bank for all such
losses and out-of-pocket expenses other than any lost margin on the Loans. Such
Bank's good faith determination of the amount of such losses or out-of-pocket
expenses, as set forth in writing and accompanied by calculations in reasonable
detail demonstrating the basis for its demand, shall be conclusively correct
absent manifest error.

                  (b) Losses subject to reimbursement hereunder shall include,
without limiting the generality of the foregoing, expenses incurred by any Bank
or any participant of such Bank permitted hereunder in connection with the
re-employment of funds prepaid, paid, repaid, not borrowed, or not paid, as the
case may be, and will be payable as a result of acceleration of the Obligations.

         Section 2.11               Pro Rata Treatment.

                  (a) Advances. Each Advance from the Banks hereunder shall be
made pro rata on the basis of the respective Commitment Ratios of the Banks.

                  (b) Payments. Except as provided in Section 2.2(e) and Article
10 hereof, each payment and prepayment of principal of the Loans and each
payment of interest on the Loans, shall be made to the Banks pro rata on the
basis of their respective unpaid principal amounts outstanding under the Notes
immediately prior to such payment or prepayment. If any Bank shall obtain any
payment (whether involuntary, through the exercise of any right of set-off, or
otherwise) on account of the Loans in excess of its ratable share of the Loans
under its Commitment Ratio, such Bank shall forthwith purchase from the other
Banks such participations in the portion of the Loans made by them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably with
each of them; provided, however, that if all or any portion of such excess
payment is thereafter recovered from such purchasing Bank, such purchase from
each Bank shall be rescinded and such Bank shall repay to the purchasing Bank
the purchase price to the extent of such recovery. The Borrower agrees that any
Bank so purchasing a participation from another Bank pursuant to this Section
2.11(b) may, to the fullest extent permitted by law, exercise all its rights of
payment (including the right of set-off) with respect to such participation as
fully as if such Bank were the direct creditor of the Borrower in the amount of
such participation.

         Section 2.12 Capital Adequacy. If after the date hereof, the adoption
of any Applicable Law regarding the capital adequacy of banks or bank holding
companies, or any change in Applicable Law (whether adopted before or after the
Agreement Date) or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Bank with any
directive regarding capital adequacy (whether or not having the force of law) of
any such governmental authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on any Bank's or any Bank's
holding company's capital as a consequence of its obligations hereunder with
respect to the Loans and the Commitments to a level below that which it could
have achieved but for such adoption, change or compliance (taking into

jurisdiction in which the character of their respective properties or the nature
of their respective businesses requires such qualification or authorization.


                                      -44-
<PAGE>   50
                  (b) Authorization; Enforceability. The Borrower has the
corporate power and has taken all necessary corporate action to authorize it to

other Loan Documents to which it is a party in accordance with their respective
terms, and to consummate the transactions contemplated hereby and thereby. This
Agreement has been duly executed and delivered by the Borrower and is, and each
of the other Loan Documents to which the Borrower is party is, a legal, valid
and binding obligation of the Borrower enforceable against the Borrower in
accordance with its terms, subject, as to enforcement of remedies, to the
following qualifications: (i) an order of specific performance and an injunction
are discretionary remedies and, in particular, may not be available where
damages are considered an adequate remedy at law, and (ii) enforcement may be
limited by bankruptcy, insolvency, liquidation, reorganization, reconstruction
and other similar laws affecting enforcement of creditors' rights generally
(insofar as any such law relates to the bankruptcy, insolvency or similar event
of the Borrower).

                  (c) Subsidiaries: Authorization; Enforceability. The
Borrower's Subsidiaries and the Borrower's direct and indirect ownership thereof

the corporate or partnership power and has taken all necessary corporate or
partnership action to authorize it to execute, deliver and perform each of the
Loan Documents to which it is a party in accordance with their respective terms
and to consummate the transactions contemplated by this Agreement and by such

specific performance and an injunction are discretionary remedies and, in
particular, may not be available where damages are considered an adequate remedy

each of its Subsidiaries represents a direct or indirect controlling interest of
such Subsidiary for purposes of directing or causing the direction of the
management and policies of each Subsidiary.

Licenses, to which the Borrower or any of its Subsidiaries is a party or by
which any of them or their respective properties may be bound, or (iv) result in
or require the creation or imposition of any Lien upon or with respect to any

the Borrower's knowledge, threatened revocation. The sole assets of each License
Sub are Licenses used in the operation and construction of the paging business
of the Borrower and the Restricted Subsidiaries and management agreements with

as well as at least 4,350,743 shares of common stock of A+ Network, Inc., a
Tennessee corporation (the "A+ Shares"). All of the A+ Shares are owned directly

which covers or purports to cover any of the assets of the Borrower or any of
the Restricted Subsidiaries is currently effective and on file in any state or
other jurisdiction, and neither the Borrower nor any of the Restricted
Subsidiaries has signed any such financing statement or filing or any security
agreement authorizing any secured party thereunder to file any such financing
statement or filing.

                  (i) Litigation. There is no action, suit, proceeding or
investigation pending against, or, to the best of the Borrower's knowledge,
threatened against or in any other manner relating adversely to, the Borrower or
any of its Subsidiaries or, to the best of the Borrower's knowledge, A+ Network,
Inc., a Tennessee corporation, or any of its Subsidiaries, any of their
respective properties, including without limitation the Licenses, in any court
or before any arbitrator of any kind or before or by any governmental body
(including without limitation the FCC) except as set forth on Schedule 8
attached hereto (as such schedule may be updated with the consent of the
Majority Banks from time to time). No such action, suit, proceeding or
investigation (i) calls into question the validity of this Agreement or any
other Loan Document, or (ii) individually or collectively involves the
possibility of any judgment or liability not fully covered by insurance which,
if determined adversely to the Borrower or any of its Subsidiaries or A+
Network, Inc., a Tennessee corporation, or any of its Subsidiaries, would have a
Materially Adverse Effect.

Borrower and each of its Subsidiaries required by law to be filed have been duly
filed and all federal, state and other taxes, including, without limitation,
withholding taxes, assessments and other governmental charges or levies required
to be paid by the Borrower or any of its Subsidiaries or imposed upon the

have been paid, except any such taxes (i) (x) the payment of which the Borrower
or any of its Subsidiaries is diligently contesting in good faith by appropriate
proceedings, (y) for which adequate reserves have been provided on the books of
the Borrower or the Subsidiary of the Borrower involved, and (z) as to which no
Lien other than a Permitted Lien has attached and no foreclosure, distraint,
sale or similar proceedings have been commenced, or (ii) which may result from
audits not yet conducted. The charges, accruals and reserves on the books of the
Borrower and each of its Subsidiaries in respect of taxes are, in the judgment
of the Borrower, adequate.

                  (k) Financial Statements. The Borrower has furnished or caused
to be furnished to the Administrative Agent and the Banks the audited financial
statements for the Borrower and its Subsidiaries on a consolidated basis for the
fiscal year ended December 31, 1995, and unaudited financial statements for the
fiscal quarter ended June 30, 1996, all of which, together with other financial
statements furnished to the Banks subsequent to the Agreement Date have been
prepared in accordance with GAAP and present fairly in all material respects the
financial position of the Borrower and the Restricted Subsidiaries on a
consolidated and consolidating basis, as the case may be, on and as at such
dates and the results of operations for the periods then ended (subject, in the
case of unaudited financial statements, to normal year-end and audit
adjustments). Neither the Borrower nor any of the Restricted Subsidiaries has
any material liabilities, contingent or otherwise, other than as disclosed in
the financial statements referred to in the preceding sentence or as set forth
or referred to in this Agreement, and there are no material unrealized losses of
the Borrower or any of the Restricted Subsidiaries and no material anticipated
losses of the Borrower or any of the Restricted Subsidiaries other than those
which have been previously disclosed in writing to the Administrative Agent and
the Banks and identified as such.

                  (l) No Material Adverse Change. Since December 31, 1995, there
has occurred no event which has had or which could reasonably be expected to
have a Materially Adverse Effect.

                  (m) ERISA. The Borrower and each Subsidiary of the Borrower
and each of their respective Plans are in compliance with ERISA and the Code and
neither the Borrower nor any of its ERISA Affiliates, including its
Subsidiaries, has incurred any accumulated funding deficiency with respect to
any such Plan within the meaning of ERISA or the Code. The Borrower, each of its
Subsidiaries, and each other ERISA Affiliate have complied with all requirements
of COBRA. Neither the Borrower nor any of its Subsidiaries has made any promises
of retirement or other benefits to employees, except as set forth in the Plans,
in


                                      -48-
<PAGE>   54
written agreements with such employees, or in the Borrower's employee handbook
and memoranda to employees. Neither the Borrower nor any of its ERISA
Affiliates, including its Subsidiaries, has incurred any material liability to
PBGC in connection with any such Plan. The assets of each such Plan which is
subject to Title IV of ERISA are sufficient to provide the benefits under such
Plan, the payment of which PBGC would guarantee if such Plan were terminated,
and such assets are also sufficient to provide all other "benefit liabilities"
(within the meaning of Section 4041 of ERISA) due under the Plan upon
termination. No Reportable Event has occurred and is continuing with respect to
any such Plan. No such Plan or trust created thereunder, or party in interest
(as defined in Section 3(14) of ERISA), or any fiduciary (as defined in Section
3(21) of ERISA), has engaged in a "prohibited transaction" (as such term is
defined in Section 406 of ERISA or Section 4975 of the Code) which would subject
such Plan or any other Plan of the Borrower or any of its Subsidiaries, any
trust created thereunder, or any such party in interest or fiduciary, or any
party dealing with any such Plan or any such trust, to the tax or penalty on
"prohibited transactions" imposed by Section 502 of ERISA or Section 4975 of the
Code. Neither the Borrower nor any of its ERISA Affiliates, including its
Subsidiaries, is or has been obligated to make any payment to a Multiemployer
Plan.

                  (n) Compliance with Regulations G, T, U and X. Neither the
Borrower nor any of the Borrower's Subsidiaries is engaged principally in or has
as one of its important activities the business of extending credit for the
purpose of purchasing or carrying, and neither the Borrower nor any of the
Borrower's Subsidiaries owns or presently intends to acquire, any "margin
security" or "margin stock" as defined in Regulations G, T, U, and X (12 C.F.R.
Parts 207, 220, 221 and 224) of the Board of Governors of the Federal Reserve
System (herein called "margin stock") other than the A+ Shares. Except with
respect to the A+ Shares, none of the proceeds of the Loans will be used,
directly or indirectly, for the purpose of purchasing or carrying any margin
stock or for the purpose of reducing or retiring any Indebtedness which was
originally incurred to purchase or carry margin stock or for any other purpose
which might constitute this transaction a "purpose credit" within the meaning of
said Regulations G, T, U, and X. The Borrower has not taken, caused or
authorized to be taken, and will not take any action which might cause this
Agreement or the Notes to violate Regulation G, T, U, or X or any other
regulation of the Board of Governors of the Federal Reserve System or to violate
the Securities Exchange Act of 1934, in each case as now in effect or as the
same may hereafter be in effect. If so requested by the Administrative Agent,
the Borrower will furnish the Administrative Agent with (i) a statement or
statements in conformity with the requirements of Federal Reserve Forms G-3
and/or U-1 referred to in


                                      -49-
<PAGE>   55
Regulations G and U of said Board of Governors and (ii) other documents
evidencing its compliance with the margin regulations, reasonably requested by
the Administrative Agent. Neither the making of the Loans nor the use of
proceeds thereof will violate, or be inconsistent with, the provisions of
Regulation G, T, U, or X of said Board of Governors.

                  (o) Investment Company Act. Neither the Borrower nor any of
its Subsidiaries is required to register under the provisions of the Investment
Company Act of 1940, as amended, and neither the entering into or performance by
the Borrower and its Subsidiaries of this Agreement and the Loan Documents nor
the issuance of the Notes violates any provision of such Act or requires any
consent, approval or authorization of, or registration with, the Securities and
Exchange Commission or any other governmental or public body or authority
pursuant to any provisions of such Act.

                  (p) Governmental Regulation. Neither the Borrower nor any of
its Subsidiaries is required to obtain any consent, approval, authorization,
permit or license which has not already been obtained from, or effect any filing
or registration which has not already been effected with, any federal, state or
local regulatory authority in connection with the execution and delivery of this
Agreement or any other Loan Document. Neither the Borrower nor any of its
Subsidiaries is required to obtain any consent, approval, authorization, permit
or license which has not already been obtained from, or effect any filing or
registration which has not already been effected with, any federal, state or
local regulatory authority in connection with the performance, in accordance
with their respective terms, of this Agreement or any other Loan Document.

                  (q) Absence of Default, Etc. The Borrower and its Subsidiaries
are in compliance in all respects with all of the provisions of their respective
partnership agreements, Certificates or Articles of Incorporation and By-Laws,
as the case may be, and no event has occurred or failed to occur (including,
without limitation, any matter which could create a Default hereunder by
cross-default) which has not been remedied or waived, the occurrence or
non-occurrence of which constitutes, (i) a Default or (ii) a material default by
the Borrower or any of its Subsidiaries, or an event or condition giving rise to
any put right or other prepayment right of any holder of Indebtedness, under any
indenture, agreement or other instrument relating to Indebtedness of the
Borrower or any of its Subsidiaries (other than as set forth on Schedule 6
attached hereto), or a default under any License (which Default could reasonably
be expected to result in an Event of Default under Section 8.1(m) hereof), or a
default under any judgment, decree or order to which the Borrower or any of its
Subsidiaries is a


                                      -50-
<PAGE>   56
party or by which the Borrower or any of its Subsidiaries or any of their
respective properties may be bound or affected. Neither the Borrower nor any of
its Subsidiaries is a party to or bound by any contract or agreement continuing
after the Agreement Date, or bound by any Applicable Law, the performance of
which or the compliance with which, as applicable, could have a Materially
Adverse Effect or result in the loss of any License issued by the FCC.

                  (r) Accuracy and Completeness of Information. All information,
reports, prospectuses and other papers and data relating to the Borrower or any
of its Subsidiaries or, to the best of the Borrower's knowledge, A+ Network,
Inc., a Tennessee corporation, or any of its Subsidiaries and furnished by or on
behalf of the Borrower or any of its Subsidiaries to the Administrative Agent or
the Banks were, at the time furnished, true, complete and correct in all
material respects to the extent necessary to give the Administrative Agent and
the Banks true and accurate knowledge of the subject matter.

                  (s) Agreements with Affiliates. Except for agreements or
arrangements with Affiliates wherein the Borrower or one or more of the
Restricted Subsidiaries provides services to such Affiliates for fair
consideration and which are set forth on Schedule 9 attached hereto, neither the
Borrower nor any of the Restricted Subsidiaries has (i) any agreements or
arrangements of any kind with any Affiliate or (ii) any management or consulting
agreements of any kind with any Affiliate.

                  (t) Payment of Wages. The Borrower and each of the Restricted
Subsidiaries are in compliance with the Fair Labor Standards Act, as amended, in
all material respects, and such Persons have paid all minimum and overtime wages
required by law to be paid to their respective employees.

                  (u) Priority. The Security Interest is a valid and perfected
first priority security interest in the Collateral in favor of the
Administrative Agent, for the benefit of itself and the Banks, securing, in
accordance with the terms of the Security Documents, the Obligations, and the
Collateral is subject to no Liens other than Permitted Liens. The Liens created
by the Security Documents are enforceable as security for the Obligations in
accordance with their terms with respect to the Collateral subject, as to
enforcement of remedies, to the following qualifications: (i) an order of
specific performance and an injunction are discretionary remedies and, in
particular, may not be available where damages are considered an adequate remedy
at law, and (ii) enforcement may be limited by bankruptcy, insolvency,
liquidation, reorganization, reconstruction and other similar laws affecting
enforcement of creditors' rights generally (insofar as any such law relates to
the bankruptcy, insolvency or


                                      -51-
<PAGE>   57
similar event of the Borrower or any of its Subsidiaries, as the case may be).
The fair market value of all partnership interests owned by the Borrower or any
of its Subsidiaries which do not constitute Collateral is less than $5,000,000
in the aggregate.

                  (v) Indebtedness for Money Borrowed. Except as described on
Schedule 10 attached hereto, neither the Borrower nor any of its Subsidiaries
has outstanding, as of the Agreement Date, and after giving effect to the
initial Advances hereunder on the Agreement Date, any Indebtedness for Money
Borrowed.

                  (w) Solvency. As of the Agreement Date and after giving effect
to the transactions contemplated by the Loan Documents and, both before and
after giving effect to the A+ Merger, (i) the property of the Borrower, at a
fair valuation, will exceed its debt; (ii) the capital of the Borrower will not
be unreasonably small to conduct its business; (iii) the Borrower will not have
incurred debts, or have intended to incur debts, beyond its ability to pay such
debts as they mature; and (iv) the present fair salable value of the assets of
the Borrower will be materially greater than the amount that will be required to
pay its probable liabilities (including debts) as they become absolute and
matured. For purposes of this Section, "debt" means any liability on a claim,
and "claim" means (i) the right to payment, whether or not such right is reduced
to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured,
undisputed, legal, equitable, secured or unsecured, or (ii) the right to an
equitable remedy for breach of performance if such breach gives rise to a right
to payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, undisputed, secured or
unsecured.

         Section 4.2 Survival of Representations and Warranties, etc. All
representations and warranties made under this Agreement and any other Loan
Document shall be deemed to be made, and shall be true and correct, at and as of
the Agreement Date and on the date of each Advance except to the extent
previously fulfilled in accordance with the terms hereof and to the extent
relating specifically to the Agreement Date. All representations and warranties
made under this Agreement and the other Loan Documents shall survive, and not be
waived by, the execution hereof by the Banks and the Administrative Agent, any
investigation or inquiry by any Bank or the Administrative Agent, or the making
of any Advance under this Agreement.

                                General Covenants

               So long as any of the Obligations is outstanding and unpaid or
the Banks have an obligation to fund Advances hereunder (whether or not the
conditions to borrowing have been or can be fulfilled), and unless the Majority
Banks, or such greater number of Banks as may be expressly provided herein,
shall otherwise consent in writing:

               Section 5.1 Preservation of Existence and Similar Matters. Except
as permitted under Section 7.4(b) below and except with respect to Subsidiaries
which are created solely for the purpose of effecting Acquisitions permitted
hereby which are dissolved immediately following the subject Acquisitions, the
Borrower will, and will cause each of the Restricted Subsidiaries to:

                                (i) preserve and maintain its existence, and its
                             material rights, franchises, licenses and
                             privileges in the state of its incorporation,
                             including, without limiting the foregoing, the
                             Licenses and all other Necessary Authorizations;
                             and

                               (ii) qualify and remain qualified and authorized
                             to do business in each jurisdiction in which the
                             character of its properties or the nature of its
                             business requires such qualification or
                             authorization.

               Section 5.2 Business; Compliance with Applicable Law. The
Borrower will, and will cause each of its Subsidiaries to, (a) engage solely in
the business of owning, constructing, managing, operating and investing in
paging service systems and communications businesses incidental or directly
relating thereto, and (b) comply in all material respects with the requirements
of all Applicable Law.

               Section 5.3 Maintenance of Properties. The Borrower will, and
will cause each of the Restricted Subsidiaries to, maintain or cause to be
maintained in the ordinary course of business in good repair, working order and
condition (reasonable wear and tear excepted) all properties used in their
respective businesses (whether owned or held under lease), other than obsolete
equipment or unused assets, and from time to time make or cause to be made all
needed and appropriate repairs, renewals, replacements, additions, betterments
and improvements thereto.

               Section 5.4 Accounting Methods and Financial Records. The
Borrower will, and will cause each of the Restricted Subsidiaries on a
consolidated and consolidating basis to,

                                      -53-
<PAGE>   59
maintain a system of accounting established and administered in accordance with
GAAP, keep adequate records and books of account in which complete entries will
be made in accordance with GAAP and reflecting all transactions required to be
reflected by GAAP, and keep accurate and complete records of their respective
properties and assets. The Borrower and the Restricted Subsidiaries will
maintain a fiscal year ending on December 31.

               Section 5.5 Insurance. The Borrower will, and will cause each of
the Restricted Subsidiaries to:

                    (a) Maintain insurance including, but not limited to,
business interruption coverage and public liability coverage insurance from
responsible companies in such amounts and against such risks to the Borrower and
each of the Restricted Subsidiaries as is prudent for similarly situated
companies engaged in the paging and wireless communications industry.

                    (b) Keep their respective assets insured by insurers on
terms and in a manner acceptable to the Administrative Agent against loss or
damage by fire, theft, burglary, loss in transit, explosions and hazards insured
against by extended coverage, in amounts which are prudent for the paging and
wireless communications industry and satisfactory to the Administrative Agent,
all premiums thereon to be paid by the Borrower and the Restricted Subsidiaries.

                    (c) Require that each insurance policy provide for at least
thirty (30) days' prior written notice to the Administrative Agent of any
termination of or proposed cancellation or nonrenewal of such policy, and name
the Administrative Agent as additional named lender loss payee and, as
appropriate, additional insured, to the extent of the Obligations.

               Section 5.6 Payment of Taxes and Claims. The Borrower will, and
will cause each of its Subsidiaries to, pay and discharge all taxes, including,
without limitation, withholding taxes, assessments and governmental charges or
levies required to be paid by them or imposed upon them or their income or
profits or upon any properties belonging to them, prior to the date on which
penalties attach thereto, and all lawful claims for labor, materials and
supplies which, if unpaid, might become a Lien or charge upon any of their
properties; except that no such tax, assessment, charge, levy or claim need be
paid which is being diligently contested in good faith by appropriate
proceedings and for which adequate reserves shall have been set aside on the
appropriate books, but only so long as such tax, assessment, charge, levy or
claim does not become a Lien or charge other than a Permitted Lien and no
foreclosure, distraint, sale or similar proceedings shall have been commenced.
The Borrower will, and

                                      -54-
<PAGE>   60
will cause each of its Subsidiaries to, timely file all information returns
required by federal, state or local tax authorities.

               Section 5.7 Compliance with ERISA.

                    (a) The Borrower shall, and shall cause its Subsidiaries to,
make all contributions to any Employee Pension Plan when such contributions are
due and not incur any "accumulated funding deficiency" within the meaning of
Section 412(a) of the Code, whether or not waived, and will otherwise comply in
all material respects with the requirements of the Code and ERISA with respect
to the operation of all Plans.

                    (b) The Borrower shall, and shall cause its Subsidiaries to,

any Plans subject to the requirements thereof.

                    (c) The Borrower shall furnish to the Administrative Agent
and the Banks (i) within thirty (30) days after any officer of the Borrower
obtains knowledge that a "prohibited transaction" (within the meaning of Section
406 of ERISA or Section 4975 of the Code) has occurred with respect to any Plan
of the Borrower or its ERISA Affiliates, including its Subsidiaries, that any
Reportable Event has occurred with respect to any Employee Pension Plan or that
PBGC has instituted or will institute proceedings under Title IV of ERISA to
terminate any Employee Pension Plan or to appoint a trustee to administer any
Employee Pension Plan, a statement setting forth the details as to such
prohibited transaction, Reportable Event or termination or appointment
proceedings and the action which it (or any other Employee Pension Plan sponsor
if other than the Borrower) proposes to take with respect thereto, together with
a copy of the notice of such Reportable Event given to PBGC if a copy of such
notice is available to the Borrower, any of its Subsidiaries or any of its ERISA
Affiliates, (ii) promptly after receipt thereof, a copy of any notice the

Department of Labor which sets forth or proposes any action or determination
with respect to such Plan, (iii) promptly after the filing thereof, any annual
report required to be filed pursuant to ERISA in connection with each Plan

request therefor, such additional information concerning any such Plan as may be
reasonably requested by the Administrative Agent or any Bank.

                                      -55-
<PAGE>   61
                    (d) The Borrower will promptly notify the Administrative
Agent and the Banks of any excise taxes which have been assessed or which the
Borrower, any of its Subsidiaries or any of its ERISA Affiliates has reason to
believe may be assessed against the Borrower, any of its Subsidiaries or any of
its ERISA Affiliates by the Internal Revenue Service or the Department of Labor
with respect to any Plan of the Borrower or its ERISA Affiliates, including its
Subsidiaries.

                    (e) Within the time required for notice to the PBGC under
Section 302(f)(4)(A) of ERISA, the Borrower will notify the Administrative Agent
and the Banks of any lien arising under Section 302(f) of ERISA in favor of any
Plan of the Borrower or its ERISA Affiliates, including its Subsidiaries.

                    (f) The Borrower will not, and will not permit any of its
Subsidiaries or any of its ERISA Affiliates to take any of the following actions
or permit any of the following events to occur if such action or event together
with all other such actions or events would subject the Borrower, any of its
Subsidiaries, or any of its ERISA Affiliates to any tax, penalty, or other
liabilities which could have a Materially Adverse Effect:

                         (i) engage in any transaction in connection with which
               the Borrower, any of its Subsidiaries or any ERISA Affiliate
               could be subject to either a civil penalty assessed pursuant to
               Section 502(i) of ERISA or a tax imposed by Section 4975 of the
               Code;

                         (ii) terminate any Employee Pension Plan in a manner,
               or take any other action, which could result in any liability of
               the Borrower, any of its Subsidiaries or any ERISA Affiliate to
               the PBGC;

                         (iii) fail to make full payment when due of all amounts
               which, under the provisions of any Plan, the Borrower, any of its
               Subsidiaries or any ERISA Affiliate is required to pay as
               contributions thereto, or permit to exist any accumulated funding
               deficiency within the meaning of Section 412(a) of the Code,
               whether or not waived, with respect to any Employee Pension Plan;
               or

                         (iv) permit the present value of all benefit
               liabilities under all Employee Pension Plans which are subject to
               Title IV of ERISA to exceed the present value of the assets of
               such Plans allocable to such benefit liabilities (within the
               meaning of Section 4041 of ERISA), except as may be permitted
               under actuarial funding standards adopted in accordance with
               Section 412 of the Code.

               Section 5.8 Visits and Inspections. The Borrower will, and will

Banks to discuss with their respective accountants the Borrower's and the
Borrower's Subsidiaries' businesses, assets, liabilities, financial positions,
results of operations and business prospects.

               Section 5.9 Payment of Indebtedness; Loans. Subject to any
provisions herein or in any other Loan Document, the Borrower will, and will
cause each of the Restricted Subsidiaries to, pay any and all of their
respective Indebtedness when and as it becomes due or to the extent of trade
payables of such Persons otherwise in accordance with ordinary business
practices customary for the wireless communications industry, other than amounts
diligently disputed in good faith and for which adequate reserves have been set
aside in accordance with GAAP.

               Section 5.10 Use of Proceeds. The Borrower will use the aggregate
proceeds of all Advances under the Facility A Commitment directly or indirectly:

Subsidiaries; (b) to refinance Indebtedness for Money Borrowed of A+ Network,
Inc. arising under the A+ Indenture after the Facility B Commitment has been
fully utilized for such purpose; (c) for working capital needs and other general
corporate purposes of the Borrower and the Restricted Subsidiaries which do not
otherwise conflict with this Section 5.10 (including, without limitation, the
payment of fees and expenses incurred in connection with the execution and
delivery of this Agreement and the other Loan Documents); and (d) subject to
compliance with Section 5.13 hereof, to finance Acquisitions permitted pursuant

Hedge Agreement between the Borrower and any other Person shall be unsecured.

or substantially adversely modified such that the Borrower and the Restricted
Subsidiaries are no longer able to operate the related paging system or portions
thereof and retain the revenue received therefrom, if any, or any such License

and the Restricted Subsidiaries are no longer able to operate the related paging
system or portions thereof and retain the revenue received therefrom, if any,
and, in either case, there shall be any loss of revenue or forecast revenue of
the Borrower or any of the Restricted Subsidiaries as a direct or indirect
result thereof; or

                         (n) Any Loan Document or any material provision

by the Borrower or any of the Borrower's Subsidiaries or any shareholder, or by
any governmental authority having jurisdiction over the Borrower or any of the

               Section 8.2 Remedies.

                         (a) If an Event of Default specified in Section 8.1
(other than an Event of Default under Section 8.1(f) or Section 8.1(g)) shall
have occurred and shall be continuing, the Administrative Agent, at the request
of the Majority Banks subject to Section 9.8(a) hereof, shall (i) terminate the
Commitments, and/or (ii) declare the principal of and interest on the Loans and
the Notes and all other amounts owed to the Banks and the Administrative Agent
under this Agreement, the Notes and any other Loan Documents to be forthwith due
and payable without presentment, demand, protest or other notice of any kind,
all of which are hereby expressly waived, anything in this Agreement, the Notes
or any other Loan Document to the contrary notwithstanding, and the Commitments
shall thereupon forthwith terminate.

                         (b) Upon the occurrence and continuance of an Event of
Default specified in Section 8.1(f) or Section 8.1(g), all principal, interest
and other amounts due hereunder and under the Notes, and all other Obligations,
shall thereupon and concurrently therewith become due and payable and the
Commitments shall forthwith terminate and the principal amount of the Loans
outstanding hereunder shall bear interest at the Default Rate, all without any
action by the Administrative Agent or the Banks, or the Majority Banks, or any
of them, and without presentment, demand, protest or other notice of any kind,
all of which are expressly waived, anything in this Agreement or in the other
Loan Documents to the contrary notwithstanding.

                         (c) Upon acceleration of the Notes, as provided in
subsection (a) or (b) of this Section 8.2, above, the Administrative Agent and
the Banks shall have all of the post-default rights granted to them, or any of
them, as applicable, under the Loan Documents and under Applicable Law.

                                      -78-
<PAGE>   84
                         (d) Following acceleration of the Notes as provided in
subsection (a) or (b) of this Section 8.2, provided the Majority Banks elect to
initiate (or direct the Administrative Agent to initiate) either (i) a civil
proceeding for the appointment of a receiver with respect to the Borrower's
assets or (ii) an involuntary bankruptcy (or similar) petition against the
Borrower, the Majority Banks shall have the right, but not the obligation, to
direct the Administrative Agent, to the extent permitted under Applicable Law,
to take possession of and to operate the paging systems of the Borrower and the
Restricted Subsidiaries during the "Pre-receivership Period," as defined below,
in accordance with the terms of the Licenses and pursuant to the terms and
subject to any limitations contained in the Security Documents and, within
guidelines established by the Majority Banks prior to such action, to make any
and all payments and expenditures necessary or desirable in connection
therewith, including, without limitation, payment of wages as required under the
Fair Labor Standards Act, as amended, and any necessary withholding taxes to
state or federal authorities. In the event the guidelines referred to in the
preceding sentence do not contemplate payments or expenditures that subsequently
arise in the ordinary course after the Administrative Agent has begun to operate
the systems, the Administrative Agent may, after giving three (3) Business Days'
notice to the Banks of its intention to do so, make such payments and
expenditures as it deems reasonable and advisable in its sole discretion to
maintain the normal day-to-day operation of such systems. All payments and
expenditures incurred in connection with this provision in excess of receipts
shall constitute costs and expenses of performance and/or collection
reimbursable by the Borrower pursuant to Section 11.2 hereof, which until paid
by the Borrower shall be reimbursed to the Administrative Agent by the Banks
pursuant to Section 9.11 hereof. No exercise by the Administrative Agent and the
Majority Banks of the rights granted to any of them under this Section 8.2(d)
shall constitute a waiver of any other rights and remedies granted to the
Administrative Agent and the Banks, or any of them, under this Agreement or any
other Loan Document or at law. The Borrower hereby irrevocably appoints the
Administrative Agent, as collateral agent for the Banks, the true and lawful
attorney of the Borrower, in its name and stead and on its behalf, to execute,
receipt for or otherwise act in connection with any and all contracts,
instruments or other documents in connection with the completion and operating
of such systems in the exercise of the Administrative Agent and Banks' rights
under this Section 8.2(d). Such power of attorney is coupled with an interest
and is irrevocable. The rights of the Administrative Agent and the Banks under
this Section 8.2(d) shall be subject to the prior compliance with the
Communications Act and the FCC rules and policies promulgated thereunder to the
extent applicable to the exercise of such rights. If the Administrative Agent
(or the Banks) take possession of the systems pursuant to

                                      -79-
<PAGE>   85
this Section 8.2(d) prior to initiation of the actions described in the first
sentence of this Section, the Administrative Agent shall initiate such action
within the time period established by the Majority Banks prior to such action.
The "Pre-receivership Period" referred to in the first sentence of this Section
8.2(d) shall mean the time period beginning on the date of the first possession
of the systems by the Administrative Agent (or the Banks) and ending upon the
earlier of (i) the taking of possession of the systems by a receiver appointed
by a court of competent jurisdiction or (ii) the taking of possession of the
systems by a trustee or by the Borrower as debtor-in-possession following the
entry of an order for relief in a case of the Borrower pending under the United
States Bankruptcy Code.

                         (e) Upon acceleration of the Notes, as provided in
subsection (a) or (b) of this Section 8.2, the Administrative Agent, upon
request of the Majority Banks, shall have the right to the appointment of a
receiver for the properties and assets of the Borrower and the Restricted
Subsidiaries, and the Borrower, for itself and on behalf of the Restricted
Subsidiaries, hereby consents to such rights and such appointment and hereby
waives any objection the Borrower or any Subsidiary may have thereto or the
right to have a bond or other security posted by the Administrative Agent on
behalf of the Banks, in connection therewith. The rights of the Administrative
Agent under this Section 8.2(e) shall be subject to its prior compliance with
the Communications Act and the FCC rules and policies promulgated thereunder to
the extent applicable to the exercise of such rights.

                         (f) The rights and remedies of the Administrative Agent
and the Banks hereunder shall be cumulative, and not exclusive.

               Section 8.3 Payments Subsequent to Declaration of Event of
Default. Subsequent to the acceleration of the Loans under Section 8.2 hereof,
payments and prepayments under this Agreement made to any of the Administrative
Agent and the Banks or otherwise received by any of such Persons (from
realization on Collateral for the Obligations or otherwise) shall be paid over
to the Administrative Agent (if necessary) and distributed by the Administrative
Agent as follows: first, to the Administrative Agent's reasonable costs and
expenses, if any, incurred in connection with the collection of such payment or
prepayment, including, without limitation, any reasonable costs incurred by it
in connection with the sale or disposition of any Collateral for the Obligations
and all amounts under Section 11.2(b) and (c); second, to the Banks and the
Administrative Agent for any fees hereunder or under any of the other Loan
Documents then due and payable; third, to the Banks pro rata on the basis of
their respective unpaid principal amounts (except as provided in

                                      -80-
<PAGE>   86
Section 2.2(e)), to the payment of any unpaid interest which may have accrued on
the Obligations; fourth, to the Banks pro rata until all Loans have been paid in
full (and, for purposes of this clause, obligations under Interest Rate Hedge
Agreements with the Banks or any of them shall be paid on a pro rata basis with
the Loans); fifth, to the Banks pro rata on the basis of their respective unpaid
amounts, to the payment of any other unpaid Obligations; and sixth, to the
Borrower or as otherwise required by law.

                                    ARTICLE 9

                            The Administrative Agent

               Section 9.1 Appointment and Authorization. Each Bank hereby
irrevocably appoints and authorizes, and hereby agrees that it will require any
transferee of any of its interest in its portion of the Loans and in its Notes
irrevocably to appoint and authorize, the Administrative Agent to take such
actions as its agent on its behalf and to exercise such powers hereunder and
under the other Loan Documents as are delegated by the terms hereof and thereof,
together with such powers as are reasonably incidental thereto. Neither the
Administrative Agent nor any of its directors, officers, employees, agents or
counsel, shall be liable for any action taken or omitted to be taken by it or
them hereunder or in connection herewith, except for its or their own gross
negligence or willful misconduct as determined by a final, non-appealable
judicial order of a court of competent jurisdiction.

               Section 9.2 Interest Holders. The Administrative Agent may treat
each Bank, or the Person designated in the last notice filed with the
Administrative Agent, as the holder of all of the interests of such Bank in its
portion of the Loans and in its Notes until written notice of transfer, signed
by such Bank (or the Person designated in the last notice filed with the
Administrative Agent) and by the Person designated in such written notice of
transfer, in form and substance satisfactory to the Administrative Agent, shall
have been filed with the Administrative Agent.

               Section 9.3 Consultation with Counsel. The Administrative Agent
may consult with Powell, Goldstein, Frazer & Murphy, Atlanta, Georgia, special
counsel to the Administrative Agent, or with other legal counsel selected by it
and shall not be liable for any action taken or suffered by it in good faith in
consultation with such counsel and in reasonable reliance on such consultations.

                                      -81-
<PAGE>   87
               Section 9.4 Documents. The Administrative Agent shall be under no
duty to examine, inquire into, or pass upon the validity, effectiveness or
genuineness of this Agreement, any Note, any other Loan Document, or any
instrument, document or communication furnished pursuant hereto or in connection
herewith, and the Administrative Agent shall be entitled to assume that they are
valid, effective and genuine, have been signed or sent by the proper parties and
are what they purport to be.

               Section 9.5 Administrative Agent and Affiliates. With respect to
the Commitments and the Loans, the Bank which is an affiliate of the
Administrative Agent shall have the same rights and powers hereunder as any
other Bank and the Administrative Agent and affiliates of the Administrative
Agent may accept deposits from, lend money to and generally engage in any kind
of business with the Borrower, any of its Subsidiaries or any Affiliates of, or
Persons doing business with, the Borrower, as if they were not affiliated with
the Administrative Agent and without any obligation to account therefor.

               Section 9.6 Responsibility of the Administrative Agent. The
duties and obligations of the Administrative Agent under this Agreement are only
those expressly set forth in this Agreement. The Administrative Agent shall be
entitled to assume that no Default or Event of Default has occurred and is
continuing unless it has actual knowledge, or has been notified in writing by
the Borrower, of such fact, or has been notified by a Bank in writing that such
Bank considers that a Default or an Event of Default has occurred and is
continuing, and such Bank shall specify in detail the nature thereof in writing.
The Administrative Agent shall not be liable hereunder for any action taken or
omitted to be taken except for its own gross negligence or willful misconduct as
determined by a final, non-appealable judicial order of a court of competent
jurisdiction. The Administrative Agent shall provide each Bank with copies of
such documents received from the Borrower as such Bank may reasonably request.

               Section 9.7 Security Documents. The Administrative Agent is
hereby authorized to act on behalf of the Banks, in its own capacity and through
other agents and sub-agents appointed by it, under the Security Documents,
provided that the Administrative Agent shall not agree to the release of any
Collateral, or any property encumbered by any mortgage, pledge or security
interest, except in compliance with Section 11.12 hereof.

               Section 9.8 Action by the Administrative Agent.

                         (a) The Administrative Agent shall be entitled to use
its discretion with respect to exercising or refraining from exercising any
rights which may be vested in it by, and with respect to taking or refraining
from taking any action or actions which it may be able to take under or in
respect of, this Agreement, unless the Administrative Agent shall have been
instructed by the Majority Banks to exercise or refrain from exercising such
rights or to take or refrain from taking such action; provided that the
Administrative Agent shall not exercise any rights under Section 8.2(a) of this
Agreement without the request of the Majority Banks (or, where expressly
required, all the Banks) unless time is of the essence. The Administrative Agent
shall incur no liability under or in respect of this Agreement with respect to
anything which it may do or refrain from doing in the reasonable exercise of its
judgment or which may seem to it to be necessary or desirable in the
circumstances, except for its gross negligence or willful misconduct as
determined by a final, non-appealable judicial order of a court of competent
jurisdiction.

                         (b) The Administrative Agent shall not be liable to the
Banks or to any Bank or the Borrower or any of the Borrower's Subsidiaries in
acting or refraining from acting under this Agreement or any other Loan Document
in accordance with the instructions of the Majority Banks (or, where expressly
required, all the Banks), and any action taken or failure to act pursuant to
such instructions shall be binding on all Banks. The Administrative Agent shall
not be obligated to take any action which is contrary to law or which would in
the Administrative Agent's reasonable opinion subject the Administrative Agent
to liability.

               Section 9.9 Notice of Default or Event of Default. In the event
that the Administrative Agent or any Bank shall acquire actual knowledge, or
shall have been notified, of any Default or Event of Default, the Administrative
Agent or such Bank shall promptly notify the Banks and the Administrative Agent,
as applicable (provided failure to give such notice shall not result in any
liability on the part of such Bank or the Administrative Agent), and the
Administrative Agent shall take such action and assert such rights under this
Agreement and the other Loan Documents as the Majority Banks shall request in
writing, and the Administrative Agent shall not be subject to any liability by
reason of its acting pursuant to any such request. If the Majority Banks shall
fail to request the Administrative Agent to take action or to assert rights
under this Agreement or any other Loan Documents in respect of any Default or
Event of Default within ten (10) days after their receipt of the notice of any
Default or Event of Default from the Administrative Agent or any

                                      -83-
<PAGE>   89
Bank, or shall request inconsistent action with respect to such Default or Event
of Default, the Administrative Agent may, but shall not be required to, take
such action and assert such rights (other than rights under Article 8 hereof) as
it deems in its discretion to be advisable for the protection of the Banks,
except that, if the Majority Banks have instructed the Administrative Agent not
to take such action or assert such right, in no event shall the Administrative
Agent act contrary to such instructions.

               Section 9.10 Responsibility Disclaimed. The Administrative Agent
shall not be under any liability or responsibility whatsoever as Administrative
Agent:

                         (a) To the Borrower or any other Person as a
consequence of any failure or delay in performance by or any breach by, any Bank
or Banks of any of its or their obligations under this Agreement;

                         (b) To any Bank or Banks, as a consequence of any
failure or delay in performance by, or any breach by, (i) the Borrower of any of
its obligations under this Agreement or the Notes or any other Loan Document, or
(ii) any Subsidiary of the Borrower or any other obligor under any other Loan
Document;

                         (c) To any Bank or Banks, for any statements,
representations or warranties in this Agreement, or any other document
contemplated by this Agreement or any information provided pursuant to this
Agreement, any other Loan Document, or any other document contemplated by this
Agreement, or for the validity, effectiveness, enforceability or sufficiency of
this Agreement, the Notes, any other Loan Document, or any other document
contemplated by this Agreement; or

                         (d) To any Person for any act or omission other than
that arising from gross negligence or willful misconduct of the Administrative
Agent as determined by a final, non-appealable judicial order of a court of
competent jurisdiction.

               Section 9.11 Indemnification. The Banks agree to indemnify the
Administrative Agent, the Managing Agents, the Syndication Agent and the
Documentation Agent (to the extent not reimbursed by the Borrower) pro rata
according to their respective Commitment Ratios, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including fees and expenses of experts, agents, consultants and
counsel), or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by or asserted against the Administrative Agent, the Managing
Agents, the Syndication Agent and the Documentation Agent in any way relating to
or arising out of this Agreement, any other Loan

                                      -84-

Document, or any other document contemplated by this Agreement or any other Loan
Document or any action taken or omitted by the Administrative Agent, the
Managing Agents, the Syndication Agent and the Documentation Agent under this
Agreement, any other Loan Document, or any other document contemplated by this
Agreement, except that no Bank shall be liable to the Administrative Agent, the
Managing Agents, the Syndication Agent and the Documentation Agent for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, or disbursements resulting from the gross
negligence or willful misconduct of such Person as determined by a final,
non-appealable judicial order of a court of competent jurisdiction.

               Section 9.12 Credit Decision. Each Bank represents and warrants
to each other and to the Administrative Agent that:

                         (a) In making its decision to enter into this Agreement
and to make its portion of the Loans it has independently taken whatever steps
it considers necessary to evaluate the financial condition and affairs of the
Borrower and that it has made an independent credit judgment, and that it has
not relied upon the Administrative Agent or information provided by the
Administrative Agent (other than information provided to the Administrative
Agent by the Borrower and forwarded by the Administrative Agent to the Banks);
and

                         (b) So long as any portion of the Loans remains
outstanding or such Bank has an obligation to make its portion of Advances
hereunder, it will continue to make its own independent evaluation of the
Collateral and of the financial condition and affairs of the Borrower.

               Section 9.13 Successor Administrative Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving written notice
thereof to the Banks and the Borrower and may be removed at any time for cause
by the Majority Banks. Upon any such resignation or removal, the Majority Banks
shall have the right to appoint a successor Administrative Agent, which
appointment shall, prior to a Default, be subject to the consent of the
Borrower, acting reasonably. If no successor Administrative Agent shall have
been so appointed by the Majority Banks and shall have accepted such appointment
within thirty (30) days after the retiring Administrative Agent gave notice of
resignation or the Majority Banks' removal of the retiring Administrative Agent,
then the retiring Administrative Agent may, on behalf of the Banks, appoint a
successor Administrative Agent which shall be any Bank or a commercial bank
organized under the laws of the United States of America or any political
subdivision thereof which has combined capital and reserves in excess of
$250,000,000. Such appointment shall, prior to a Default, be

                                      -85-
<PAGE>   91
subject to the consent of the Borrower, acting reasonably. Upon the acceptance
of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges, duties and
obligations of the retiring Administrative Agent and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder and under
the other Loan Documents. After any retiring Administrative Agent's resignation
or removal hereunder as Administrative Agent the provisions of this Article
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent.

               Section 9.14 Delegation of Duties. The Administrative Agent may
execute any of its duties under the Loan Documents by or through agents or
attorneys selected by it using reasonable care, and shall be entitled to advice
of counsel concerning all matters pertaining to such duties.

                                   ARTICLE 10

                             Change in Circumstances

                          Affecting Eurodollar Advances

               Section 10.1 Eurodollar Basis Determination Inadequate or Unfair.
If with respect to any proposed Eurodollar Advance for any Interest Period, the
Administrative Agent determines after consultation with the Banks that deposits
in dollars (in the applicable amount) are not being offered to each of the Banks
in the relevant market for such Interest Period, the Administrative Agent shall
forthwith give notice thereof to the Borrower and the Banks, whereupon until the
Administrative Agent notifies the Borrower that the circumstances giving rise to
such situation no longer exist, the obligations of any affected Bank to make its
portion of such type of Eurodollar Advances shall be suspended.

               Section 10.2 Illegality. If after the date hereof, the adoption
of any Applicable Law, or any change in any Applicable Law (whether adopted
before or after the Agreement Date), or any change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank with any directive (whether or not having the force of law) of any
such authority, central bank or comparable agency, shall make it unlawful or
impossible for any Bank to make, maintain or fund its portion of Eurodollar
Advances, such Bank shall so notify the Administrative Agent, and the
Administrative Agent shall forthwith give notice thereof to the other Banks and
the Borrower. Before giving any notice to the Administrative

                                      -86-
<PAGE>   92
Agent pursuant to this Section 10.2, such Bank shall designate a different
lending office if such designation will avoid the need for giving such notice
and will not, in the sole judgment of such Bank, be otherwise materially
disadvantageous to such Bank. Upon receipt of such notice, notwithstanding
anything contained in Article 2 hereof, the Borrower shall repay in full the
then outstanding principal amount of such Bank's portion of each affected
Eurodollar Advance, together with accrued interest thereon, on either (a) the
last day of the then current Interest Period applicable to such affected
Eurodollar Advances if such Bank may lawfully continue to maintain and fund its
portion of such Eurodollar Advance to such day or (b) immediately if such Bank
may not lawfully continue to fund and maintain its portion of such affected
Eurodollar Advances to such day. Concurrently with repaying such portion of each
affected Eurodollar Advance, the Borrower may borrow a Base Rate Advance from
such Bank, and such Bank shall make such Advance, if so requested, in an amount
such that the outstanding principal amount of the affected Note held by such
Bank shall equal the outstanding principal amount of such Note or Notes
immediately prior to such repayment.

               Section 10.3 Increased Costs.

                         (a) If after the date hereof, the adoption of any
Applicable Law, or any change in any Applicable Law (whether adopted before or
after the Agreement Date), or any interpretation or change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof or compliance
by any Bank with any directive (whether or not having the force of law) of any
such authority, central bank or comparable agency:

                         (1) shall subject any Bank to any tax, duty or other
               charge with respect to its obligation to make its portion of
               Eurodollar Advances, or its portion of existing Advances, or
               shall change the basis of taxation of payments to any Bank of the
               principal of or interest on its portion of Eurodollar Advances or
               in respect of any other amounts due under this Agreement, in
               respect of its portion of Eurodollar Advances or its obligation
               to make its portion of Eurodollar Advances (except for changes in
               the rate or method of calculation of tax on the overall net
               income of such Bank); or

                         (2) shall impose, modify or deem applicable any reserve
               (including, without limitation, any imposed by the Board of
               Governors of the Federal Reserve System, but excluding any
               included in an applicable Eurodollar Reserve Percentage), special
               deposit, capital adequacy, assessment or other requirement or
               condition against assets of,

                                      -87-
<PAGE>   93
               deposits with or for the account of, or commitments or credit
               extended by, any Bank or shall impose on any Bank or the London
               interbank borrowing market any other condition affecting its
               obligation to make its portion of such Eurodollar Advances or its
               portion of existing Advances;

and the result of any of the foregoing is to increase the cost to such Bank of
making or maintaining any of its portion of Eurodollar Advances, or to reduce
the amount of any sum received or receivable by such Bank under this Agreement
or under its Note with respect thereto, then, on the earlier of a date within
ten (10) days after demand by such Bank or the Maturity Date, the Borrower
agrees to pay to such Bank such additional amount or amounts as will compensate
such Bank for such increased costs. Each Bank will promptly notify the Borrower
and the Administrative Agent of any event of which it has knowledge, occurring
after the date hereof, which will entitle such Bank to compensation pursuant to
this Section 10.3 and will designate a different lending office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the sole judgment of such Bank made in good faith, be otherwise
disadvantageous to such Bank.

                         (b) Any Bank claiming compensation under this Section
10.3 shall provide the Borrower with a written certificate setting forth the
additional amount or amounts to be paid to it hereunder and calculations
therefor in reasonable detail. Such certificate shall be presumptively correct
absent manifest error. In determining such amount, such Bank may use any
reasonable averaging and attribution methods. If any Bank demands compensation
under this Section 10.3, the Borrower may at any time, upon at least five (5)
Business Days' prior notice to such Bank, prepay in full such Bank's portion of
the then outstanding Eurodollar Advances, together with accrued interest thereon
to the date of prepayment, along with any reimbursement required under Section
2.10 hereof. Concurrently with prepaying such portion of Eurodollar Advances the
Borrower may borrow a Base Rate Advance, or a Eurodollar Advance not so
affected, from such Bank, and such Bank shall, if so requested, make such
Advance in an amount such that the outstanding principal amount of the affected
Note or Notes held by such Bank shall equal the outstanding principal amount of
such Note or Notes immediately prior to such prepayment.

               Section 10.4 Effect On Other Advances. If notice has been given
pursuant to Section 10.1, 10.2 or 10.3 suspending the obligation of any Bank to
make its portion of any type of Eurodollar Advance, or requiring such Bank's
portion of Eurodollar Advances to be repaid or prepaid, then, unless and until
such Bank notifies the Borrower that the circumstances giving rise to such
repayment no longer apply, all amounts which

                                      -88-
<PAGE>   94
would otherwise be made by such Bank as its portion of Eurodollar Advances
shall, unless otherwise notified by the Borrower, be made instead as Base Rate
Advances.

               Section 11.2 Expenses. The Borrower will promptly pay, or
reimburse:

                         (a) all out-of-pocket expenses of the Administrative
Agent, the Managing Agents, the Syndication Agent and the Documentation Agent in
connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Loan Documents, and the transactions contemplated
hereunder and thereunder and the making of the initial Advance hereunder
(whether or not such Advance is made), including, but not limited to, the fees
and disbursements of Powell, Goldstein, Frazer & Murphy, special counsel for the
Administrative Agent;

                         (b) all out-of-pocket expenses of the Administrative
Agent, the Managing Agents, the Syndication Agent and the Documentation Agent in
connection with the restructuring and "work out" of the transactions
contemplated in this Agreement or the other Loan Documents, and the preparation,
negotiation, execution and delivery of any waiver, amendment or consent by the
Administrative Agent and the Banks, or any of them, relating to this Agreement
or the other Loan Documents, including, but not limited to, the fees and
disbursements of any experts, agents or consultants and of special counsel for
the Administrative Agent; and

                         (c) all out-of-pocket costs and expenses of obtaining
performance under this Agreement or the other Loan Documents and all
out-of-pocket costs and expenses of collection if an Event of 

                                      -90-
<PAGE>   96
Default occurs in the payment of the Notes, which in each case shall include
fees and out-of-pocket expenses of counsel for the Administrative Agent, the
Managing Agents, the Syndication Agent and the Documentation Agent and the
Banks.

               Section 11.3 Waivers. The rights and remedies of the
Administrative Agent and the Banks under this Agreement and the other Loan
Documents shall be cumulative and not exclusive of any rights or remedies which
they would otherwise have. No failure or delay by the Administrative Agent, the
Majority Banks, or the Banks, or any of them, in exercising any right, shall
operate as a waiver of such right. The Administrative Agent and the Banks
expressly reserve the right to require strict compliance with the terms of this
Agreement in connection with any future funding of a Request for Advance. In the
event the Banks decide to fund a Request for Advance at a time when the Borrower
is not in strict compliance with the terms of this Agreement, such decision by
the Banks shall not be deemed to constitute an undertaking by the Banks to fund
any further Request for Advance or preclude the Banks or the Administrative
Agent from exercising any rights available under the Loan Documents or at law or
equity. Any waiver or indulgence granted by the Administrative Agent, the Banks,
or the Majority Banks, or any of them, shall not constitute a modification of
this Agreement or any other Loan Document, except to the extent expressly
provided in such waiver or indulgence, or constitute a course of dealing at
variance with the terms of this Agreement or any other Loan Document such as to
require further notice of their intent to require strict adherence to the terms
of this Agreement or any other Loan Document in the future.

               Section 11.4 Set-Off. In addition to any rights now or hereafter
granted under Applicable Law and not by way of limitation of any such rights,
upon the occurrence of an Event of Default and during the continuation thereof,
the Administrative Agent and each of the Banks are hereby authorized by the
Borrower at any time or from time to time, without notice to the Borrower or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and to apply any and all deposits (general or special, time or
demand, including, but not limited to, Indebtedness evidenced by certificates of
deposit, in each case whether matured or unmatured) and any other Indebtedness
at any time held or owing by any Bank or the Administrative Agent, to or for the
credit or the account of the Borrower or any of its Subsidiaries, against and on
account of the obligations and liabilities of the Borrower to the Banks and the
Administrative Agent, including, but not limited to, all Obligations and any
other claims of any nature or description arising out of or connected with this
Agreement, the Notes or any other Loan Document, irrespective of whether (a) any
Bank or the Administrative Agent shall have made any demand hereunder or

                                      -91-
<PAGE>   97
(b) any Bank or the Administrative Agent shall have
declared the principal of and interest on the Loans and other amounts due
hereunder to be due and payable as permitted by Section 8.2 and although such
obligations and liabilities or any of them shall be contingent or unmatured.
Upon direction by the Administrative Agent with the consent of the Banks, each
Bank holding deposits of the Borrower or any of its Subsidiaries shall exercise
its set-off rights as so directed.

               Section 11.5 Assignment.

                         (a) The Borrower may not assign or transfer any of its
rights or obligations hereunder, under the Notes or under any other Loan
Document without the prior written consent of each Bank.

                         (b) Each Bank may sell assignments or participations of
one hundred percent (100%) of its interests hereunder to (A) one or more
affiliates of such Bank, or (B) any Federal Reserve Bank as collateral security
pursuant to Regulation A of the Board of Governors of the Federal Reserve System
and any Operating Circular issued by such Federal Reserve Bank without
limitation.

                         (c) Each of the Banks may at any time enter into
assignment agreements or participations with one or more other banks or other
Persons pursuant to which such Bank may assign or participate its interests
under this Agreement and the other Loan Documents, including its interest in any
particular Advance or portion thereof, provided, that all assignments and
participations (other than assignments to another Bank, which may be made
without limitation, whether as to dollar amount or otherwise, so long as, (x) if
such assignment takes place after the occurrence of an Event of Default such
assignment is made with the prior written consent of the Administrative Agent,
which consent shall not be unreasonably withheld, and, (y) in any event, such
assignments are made pro rata as provided in clause (v) below, and other
assignments and participations described in Section 11.5(b) which may be made
without any limitation whatsoever) shall be in minimum principal amounts of

conditions:

                         (i) No assignment shall be sold without the prior
               consent of the Administrative Agent and, prior to the occurrence
               of an Event of Default, the consent of the Borrower, which
               consents shall not be unreasonably withheld;

                         (ii) Any Person purchasing a participation or an
               assignment of any portion of the Loans from any Bank shall be
               required to represent and warrant that its purchase shall

<PAGE>   98
               not constitute a "prohibited transaction" (as defined in Section
               4.1(m) hereof);

                         (iii) Assignments permitted hereunder (including the
               assignment of any Advance or portion thereof) may be made with
               all voting rights, and shall be made pursuant to an Assignment
               and Assumption Agreement substantially in the form of Exhibit M
               attached hereto;

                         (iv) An administrative fee of $2,500 shall be payable
               to the Administrative Agent by the assigning Bank at the time of
               any assignment hereunder;

                         (v) Any Bank making an assignment of its rights and
               obligations under either Commitment shall also make an assignment
               of an equal percentage of its outstanding Loans under such
               Commitment and of its rights and obligations under the other
               Commitment and its outstanding Loans thereunder;

                         (vi) No participation agreement shall confer any rights
               under this Agreement or any other Loan Document to any purchaser
               thereof, or relieve any issuing Bank from any of its obligations
               under this Agreement, and all actions hereunder shall be
               conducted as if no such participation had been granted; provided,
               however, that any participation agreement may confer on the
               participant the right to approve or disapprove decreases in the
               interest rate, increases in the principal amount of the Loans
               participated in by such participant, decreases in fees,
               extensions of the Maturity Date or other principal payment date
               for the Loans or of a scheduled reduction of either Commitment or
               releases of Collateral or any Subsidiary Guaranty;

                         (vii) Each Bank agrees to provide the Administrative
               Agent and the Borrower with prompt written notice of any issuance
               of participations in or assignments of its interests hereunder;

                         (viii) No assignment, participation or other transfer
               of any rights hereunder or under the Notes shall be effected that
               would result in any interest requiring registration under the
               Securities Act of 1933, as amended, or qualification under any
               state securities law;

                         (ix) No such assignment may be made to any bank or
               other financial institution (x) with respect to which a receiver
               or conservator (including, without limitation, the Federal
               Deposit Insurance Corporation, the Resolution Trust Company or
               the Office of Thrift Supervision) has been appointed or (y) that
               is not "adequately capitalized" (as 

                                      -93-
<PAGE>   99
               such term is defined in Section 131(b)(1)(B) of the Federal
               Deposit Insurance Corporation Improvement Act as in effect on the
               Agreement Date); and

                         (x) If applicable, each Bank shall, and shall cause
               each of its assignees to, provide to the Administrative Agent on
               or prior to the effective date of any assignment an appropriate
               Internal Revenue Service form as required by Applicable Law
               supporting such Bank's or assignee's position that no withholding
               by the Borrower or the Administrative Agent for U.S. income tax
               payable by such Bank or assignee in respect of amounts received
               by it hereunder is required. For purposes of this Agreement, an
               appropriate Internal Revenue Service form shall mean Form 1001
               (Ownership Exemption or Reduced Rate Certificate of the U.S.
               Department of Treasury), or Form 4224 (Exemption from Withholding
               of Tax on Income Effectively Connected with the Conduct of a
               Trade or Business in the United States), or any successor or
               related forms adopted by the relevant U.S. taxing authorities.

                         (d) Except as specifically set forth in Section 11.5(c)
hereof, nothing in this Agreement or the Notes, expressed or implied, is
intended to or shall confer on any Person other than the respective parties
hereto and thereto and their successors and assignees permitted hereunder and
thereunder any benefit or any legal or equitable right, remedy or other claim
under this Agreement or the Notes.

                         (e) In the case of any participation, all amounts
payable by the Borrower under the Loan Documents shall be calculated and made in
the manner and to the parties hereto as if no such participation had been sold.

                         (f) The provisions of this Section 11.5 shall not apply
to any purchase of participations among the Banks pursuant to Section 2.11
hereof.

               Section 11.6 Accounting Principles. All references in this
Agreement to GAAP shall be to such principles as in effect from time to time.
All accounting terms used herein without definition shall be used as defined
under GAAP. All references to the financial statements of the Borrower and to
its Net Income, Operating Cash Flow, Senior Debt, Total Debt, Interest Expense,
Pro Forma Debt Service, and other such terms shall be deemed to refer to such
items of the Borrower and the Restricted Subsidiaries, on a fully consolidated
basis.

               Section 11.7 Counterparts. This Agreement may be executed in any
number of counterparts, each of which shall be deemed to

                                      -94-
<PAGE>   100
be an original, but all such separate counterparts shall together constitute but
one and the same instrument.

               Section 11.8 Governing Law. This Agreement and the Notes shall be
construed in accordance with and governed by the internal laws of the State of
New York applicable to agreements made and to be performed in New York. If any
action or proceeding shall be brought by the Administrative Agent or any Bank
hereunder or under any other Loan Document in order to enforce any right or
remedy under this Agreement or under any Note or any other Loan Document, the
Borrower hereby consents and will, and the Borrower will cause each Subsidiary
to, submit to the jurisdiction of any state or federal court of competent
jurisdiction sitting within the area comprising the Southern District of New
York on the date of this Agreement. The Borrower, for itself and on behalf of
its Subsidiaries, hereby agrees that service of the summons and complaint and
all other process which may be served in any such suit, action or proceeding may
be effected by mailing by registered mail a copy of such process to the offices
of the Borrower at the address given in Section 11.1 hereof and that personal
service of process shall not be required. Nothing herein shall be construed to
prohibit service of process by any other method permitted by law, or the
bringing of any suit, action or proceeding in any other jurisdiction. The
Borrower agrees that final judgment in such suit, action or proceeding shall be
conclusive and may be enforced in any other jurisdiction by suit on the judgment
or in any other manner provided by Applicable Law.

               Section 11.9 Severability. Any provision of this Agreement which
is prohibited or unenforceable in any jurisdiction shall be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof in that jurisdiction or affecting the validity or
enforceability of such provision in any other jurisdiction.

               Section 11.10 Interest.

                         (a) In no event shall the amount of interest due or
payable hereunder or under the Notes exceed the maximum rate of interest allowed
by Applicable Law, and in the event any such payment is inadvertently made by
the Borrower or inadvertently received by the Administrative Agent or any Bank,
then such excess sum shall be credited as a payment of principal, unless the
Borrower shall notify the Administrative Agent or such Bank, in writing, that it
elects to have such excess sum returned forthwith. It is the express intent
hereof that the Borrower not pay and the Administrative Agent and the Banks not
receive, directly or indirectly in any manner whatsoever, interest in

                                      -95-
<PAGE>   101
excess of that which may legally be paid by the Borrower under Applicable Law.

                         (b) Notwithstanding the use by the Banks of the Base
Rate and the Eurodollar Rate as reference rates for the determination of
interest on the Loans, the Banks shall be under no obligation to obtain funds
from any particular source in order to charge interest to the Borrower at
interest rates related to such reference rates.

               Section 11.11 Table of Contents and Headings. The Table of
Contents and the headings of the various subdivisions used in this Agreement are
for convenience only and shall not in any way modify or amend any of the terms
or provisions hereof, nor be used in connection with the interpretation of any
provision hereof.

               Section 11.12 Amendment and Waiver. Neither this Agreement nor
any term hereof may be amended orally, nor may any provision hereof be waived
orally but only by an instrument in writing signed by the Majority Banks and the
Administrative Agent and, in the case of an amendment, by the Borrower, except
that in the event of (a) any increase in the amount of either Commitment, (b)
any delay or extension in the terms of repayment of the Loans or any mandatory
reductions in either Commitment provided in Sections 2.5 or 2.7 hereof, (c) any
reduction in principal, interest or fees due hereunder or postponement of the
payment thereof without a corresponding payment by the Borrower, (d) any release
of any portion of the Collateral for the Loans, except in connection with a
merger, sale or other disposition otherwise permitted hereunder (in which case
such release shall require no further approval by the Banks), (e) any waiver of
any Default due to the failure by the Borrower to pay any sum due to any of the
Banks hereunder, (f) any release of any Guaranty of all or any portion of the
Obligations, except in connection with a merger, sale or other disposition
otherwise permitted hereunder (in which case, such release shall require no
further approval by the Banks), or (g) any amendment of this Section 11.12, of
the definition of Majority Banks, or of any Section herein to the extent that
such Section requires action by all Banks, any amendment or waiver or consent
may be made only by an instrument in writing signed by each of the Banks and the
Administrative Agent and, in the case of an amendment, by the Borrower. Any
amendment to any provision hereunder governing the rights, obligations, or
liabilities of the Administrative Agent may be made only by an instrument in
writing signed by the Administrative Agent and by each of the Banks.

               Section 11.13 Entire Agreement. Except as otherwise expressly
provided herein, this Agreement and the other documents described or
contemplated herein will embody the entire agreement

                                      -96-
<PAGE>   102
and understanding among the parties hereto and thereto and supersede all prior
agreements and understandings relating to the subject matter hereof and thereof.

               Section 11.14 Other Relationships. No relationship created
hereunder or under any other Loan Document shall in any way affect the ability
of the Administrative Agent and each Bank to enter into or maintain business
relationships with the Borrower or any of its Affiliates beyond the
relationships specifically contemplated by this Agreement and the other Loan
Documents.

               Section 11.15 Directly or Indirectly. If any provision in this
Agreement refers to any action taken or to be taken by any Person, or which such
Person is prohibited from taking, such provision shall be applicable whether
such action is taken directly or indirectly by such Person, whether or not
expressly specified in such provision.

               Section 11.16 Reliance on and Survival of Various Provisions. All
covenants, agreements, statements, representations and warranties made herein or
in any certificate delivered pursuant hereto (i) shall be deemed to have been
relied upon by the Administrative Agent and each of the Banks notwithstanding
any investigation heretofore or hereafter made by any of them, and (ii) shall
survive the execution and delivery of the Notes and shall continue in full force
and effect so long as any Note is outstanding and unpaid. Any right to
indemnification hereunder, including, without limitation, rights pursuant to
Sections 2.10, 2.12, 5.11, 10.3 and 11.2 hereof, shall survive the termination
of this Agreement and the payment and performance of all Obligations.

               Section 11.17 Senior Debt. The Obligations are secured by the
Security Documents and are intended by the parties hereto to be senior in right
of payment to all other Indebtedness of the Borrower.

               Section 11.18 Obligations Several. The obligations of the
Administrative Agent and each of the Banks hereunder are several, not joint.

                                    EXHIBIT A

            FORM OF AMENDED AND RESTATED BORROWER'S PLEDGE AGREEMENT

         THIS AMENDED AND RESTATED BORROWER'S PLEDGE AGREEMENT (the
"Agreement"), entered into as of this 20th day of September, 1996, by and
between Metrocall, Inc., a Delaware corporation (the "Borrower"), and Toronto
Dominion (Texas), Inc., as administrative agent (the "Administrative Agent") for
itself and on behalf of the Managing Agents, the Documentation Agent, the
Syndication Agent (each as described below) and the Banks (as defined in the
Loan Agreement defined below),

                              W I T N E S S E T H:

         WHEREAS, the Borrower, the Banks, The First National Bank of Boston, as
syndication agent (in such capacity, the "Syndication Agent"), The
Toronto-Dominion Bank, as documentation agent (in such capacity, the
"Documentation Agent"), The Toronto-Dominion Bank and The First National Bank of
Boston, as managing agents for the Banks (collectively, in such capacity, the
"Managing Agents"), and the Administrative Agent are all parties to that certain
Amended and Restated Loan Agreement dated as of September 20, 1996 (as amended,
restated or otherwise modified or replaced from time to time, the "Loan
Agreement"); and

         WHEREAS, as a condition precedent to the effectiveness of the Loan
Agreement, the Borrower is required to execute and deliver this Agreement, which
amends, restates, restructures, renews and extends, extends, consolidates,
supplements, modifies, supercedes and replaces in its entirety that certain
Borrower's Pledge Agreement dated as of August 31, 1994 by and between the
Borrower and the Administrative Agent, as heretofore amended, restated,
supplemented or otherwise modified (the "Original Security Document"); and

         WHEREAS, the Borrower acknowledges and agrees that the parties hereto
intend that this Agreement and the collateral furnished hereunder and under the
Original Security Document shall secure, without interruption or impairment of
any kind, all existing indebtedness secured by the Original Security Document
and all other Obligations (as defined herein), and the Borrower hereby ratifies,
confirms and agrees to continue in effect all Liens evidenced by the Original
Security Document, without interruption or impairment of any kind; and

         WHEREAS, the Administrative Agent has agreed to act as administrative
agent for itself and on behalf of the Managing Agents, the Documentation Agent,
the Syndication Agent and the
<PAGE>   107
Banks in connection with the transactions contemplated by the Loan Agreement; 
and

         WHEREAS, to secure the payment and performance of, among other things,
all obligations of the Borrower under the Loan Agreement and the promissory
notes issued by the Borrower to the Banks thereunder (the "Notes"), the Borrower
and the Administrative Agent (on behalf of itself, the Managing Agents, the
Documentation Agent, the Syndication Agent and the Banks) have agreed that the
shares of capital stock (the "Stock") owned by the Borrower in each of the
Subsidiaries of the Borrower listed on Schedule 1 attached hereto (the
"Subsidiaries"), which are the only directly owned corporate Subsidiaries of the
Borrower, shall be pledged by the Borrower to the Administrative Agent (on
behalf of itself, the Managing Agents, the Documentation Agent, the Syndication
Agent and the Banks) to secure the Obligations (as defined in the Loan
Agreement);

         NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree that capitalized terms used herein shall
have the meanings ascribed to them in the Loan Agreement to the extent not
otherwise defined or limited herein, and further agree as follows:

         1.    Warranty. The Borrower hereby represents and warrants to the
Administrative Agent, the Managing Agents, the Documentation Agent, the
Syndication Agent and the Banks that, except for the security interest created
hereby, the Borrower owns the Stock, which constitutes the percentage of the
issued and outstanding capital stock of each Subsidiary as set forth on Schedule
1 attached hereto, free and clear of all Liens, that the Stock is duly issued,
fully paid and non-assessable, and that the Borrower has the unencumbered right
to pledge the Stock. In addition, the Borrower represents and covenants as
follows: (1) the Stock represents all of the Borrower's shares of capital stock
in each Subsidiary of the Borrower; (2) upon possession of the Stock by the
Administrative Agent, the Administrative Agent shall have a valid and perfected
first priority security interest in the Stock, securing the payment of the
Obligations; and (3) except as noted on Schedule 2 attached hereto, the Stock
represents all of the outstanding shares of stock issued by any direct
Subsidiary of the Borrower.

         2.    Security Interest.  The Borrower hereby unconditionally grants 
and assigns to the Administrative Agent, for itself and on behalf of the
Managing Agents, the Documentation Agent, the Syndication Agent and the Banks,
and their respective successors and assigns, a continuing security interest in
and security title to the Stock and any other shares of capital stock of any


                                      - 2 -
<PAGE>   108
Subsidiary of the Borrower obtained in the future, and in each case, all
certificates representing such shares, all rights, options, warrant, stock or
other securities or other property which may hereafter be received, receivable
or distributed in respect of the Stock, together with all proceeds of the
foregoing, including, without limitation, all dividends, cash, notes, securities
or other property from time to time acquired, receivable or otherwise
distributed in respect of, or in exchange for, the foregoing, all of which shall
constitute "Stock" hereunder. The Borrower herewith delivers to and deposits
with the Administrative Agent all of its right, title and interest in and to the
Stock, together with certificates representing the Stock, and undated stock
powers endorsed in blank, as security for the Obligations; it being the
intention of the parties hereto that beneficial ownership of the Stock,
including, without limitation, all voting, consensual and dividend rights, shall
remain in the Borrower until the occurrence of an Event of Default under the
terms of the Loan Agreement and until the Administrative Agent shall notify the
Borrower of the Administrative Agent's exercise of voting and dividend rights to
the Stock pursuant to Section 9 of this Agreement.

         3.       Additional Shares.  In the event that, during the term of this
Agreement:

                  (a)   any stock dividend, stock split, reclassification,
         readjustment, or other change is declared or made in the capital
         structure of any directly owned Subsidiary, or any new stock is issued
         by such Subsidiary, or any new directly owned Subsidiary is formed or
         acquired, then, in any such event, all new, substituted, and additional
         shares, or other securities, which are issued to the Borrower in
         connection therewith shall be promptly delivered to the Administrative
         Agent, together with undated stock powers endorsed in blank by the
         Borrower, and shall thereupon constitute Stock to be held by the
         Administrative Agent under the terms of this Agreement; and

                  (b)   any subscriptions, warrants or any other rights or 
         options shall be issued in connection with the Stock, all new stock or
         other securities acquired through such subscriptions, warrants, rights
         or options by the Borrower shall be promptly delivered to the
         Administrative Agent, together with undated stock powers endorsed in
         blank, and shall thereupon constitute Stock to be held by the
         Administrative Agent under the terms of this Agreement.

         4.       Default.  In the event of the occurrence of an Event of
Default and so long as any such Event of Default is continuing, and subject to
Section 13 hereof, the Administrative Agent may sell or otherwise dispose of the
Stock at a public or private


                                      - 3 -
<PAGE>   109
sale or make other commercially reasonable disposition of the Stock or any
portion thereof after fifteen (15) days' notice to the Borrower, and the
Administrative Agent, the Managing Agents, the Documentation Agent, the
Syndication Agent and the Banks, or any of them, may purchase the Stock or any
portion thereof at any public sale. The proceeds of the public or private sale
or other disposition shall be applied first to the costs of the Administrative
Agent incurred in connection with the sale, expressly including, without
limitation, any costs under Section 7 hereof, and then to the Obligations as
provided in the Loan Agreement. In the event the proceeds of the sale or other
disposition of the Stock are insufficient to satisfy the Obligations, the
Borrower shall remain liable for any such deficiency. The Borrower waives the
rights of equity of redemption, appraisal, notice of acceptance, presentment,
demand and marshalling, to the extent applicable.

         5.   Additional Rights of Secured Party. In addition to its rights and
privileges under this Agreement, the Administrative Agent, on behalf of itself,
the Managing Agents, the Documentation Agent, the Syndication Agent and the
Banks, shall have all the rights, powers and privileges of a secured party under
the Uniform Commercial Code as in effect in any applicable jurisdiction and
other Applicable Law.

         6.   Return of Stock to the Borrower. Upon payment in full of all
principal and interest on the Notes, full performance by the Borrower of all
covenants, undertakings and obligations under the Loan Agreement, the Notes, and
the other Loan Documents, and satisfaction in full of any other Obligations,
other than the Obligations which survive the termination of the Loan Agreement
as provided in Section 11.16 of the Loan Agreement, and after such time as the
Banks shall have no obligation to make any further Advances to the Borrower,
this Agreement shall terminate and the Administrative Agent shall return the
remaining Stock and all rights received by the Administrative Agent as a result
of its possessory interest in the Stock to the Borrower.

         7.   Disposition of Stock by Administrative Agent. The Stock is not
registered or qualified under the various Federal or state securities laws of
the United States, and disposition thereof after default may be restricted to
one or more private (instead of public) sales. The Borrower understands that
upon such disposition, the Administrative Agent may approach only a restricted
number of potential purchasers and further understands that a sale under such
circumstances may yield a lower price for the Stock than if the Stock were
registered and qualified pursuant to Federal and state securities laws and sold
on the open market. The Borrower, therefore, agrees that:


                                      - 4 -
<PAGE>   110
                  (a)   if the Administrative Agent shall, pursuant to the terms
         of this Agreement, sell or cause the Stock or any portion thereof to be
         sold at a private sale, the Administrative Agent shall have the right
         to rely upon the advice and opinion of any national brokerage or
         investment firm having recognized expertise and experience in
         connection with shares of companies providing paging and related
         wireless communication services (but shall not be obligated to seek
         such advice and the failure to do so shall not be considered in
         determining the commercial reasonableness of such action) as to the
         best manner in which to expose the Stock for sale and as to the best
         price reasonably obtainable at the private sale thereof; and

                  (b)   that such reliance shall be conclusive evidence that the
         Administrative Agent has handled such disposition in a commercially
         reasonable manner.

         8.       Borrower's Obligations Absolute. The obligations of the
Borrower under this Agreement shall be direct and immediate and not conditional
or contingent upon the pursuit of any remedies against the Borrower or any other
Person, nor against other security or liens available to the Administrative
Agent, either Managing Agent, the Documentation Agent, the Syndication Agent or
any Bank. The Borrower hereby waives any right to require that an action be
brought against any other Person or to require that resort be had to any other
security or to any balance of any deposit account or credit on the books of the
Administrative Agent, the Managing Agents, the Documentation Agent, the
Syndication Agent or any of the Banks in favor of any other Person prior to the
exercise of remedies hereunder, or to require action hereunder prior to resort
by the Administrative Agent to any other security or collateral for the Notes
and the other Obligations. No amendment, modification, waiver, transfer or
renewal, extension, assignment or termination of this Agreement or of the Loan
Agreement or of any other Loan Document, or of any instrument or document
executed and delivered by the Borrower or any other obligor to the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, nor additional advances made by the Banks
and the Administrative Agent, or any of them, to the Borrower, nor the taking of
further security, nor the retaking or re-delivery or release of the Collateral
to the Borrower or any other collateral or guaranty by the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, nor any lack of validity or enforceability
of any Loan Document or any term thereof, nor any other act of the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, shall release the Borrower from any
Obligation, except a release or discharge executed in


                                      - 5 -
<PAGE>   111
writing by the Administrative Agent in accordance with the Loan Agreement with
respect to such Obligation or upon full payment and satisfaction of all
Obligations. None of the Administrative Agent, either Managing Agent, the
Documentation Agent, the Syndication Agent or any Bank shall, by any act, delay,
omission or otherwise, be deemed to have waived any of its or their rights or
remedies hereunder, unless such waiver is in writing and signed by the
Administrative Agent in accordance with the Loan Agreement and then only to the
extent therein set forth. A waiver by the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, of any right or remedy on any occasion shall not be construed as a bar to
the exercise of any such right or remedy which any such Person would otherwise
have had on any other occasion.

         9.       Voting Rights.

                  (a)   For so long as the Notes or any other Obligations remain
         unpaid, after and during the continuation of an Event of Default, but
         subject to the provisions of Section 13 hereof, (i) the Administrative
         Agent may, upon fifteen (15) days' prior written notice to the Borrower
         of its intention to do so, exercise all voting rights, and all other
         ownership or consensual rights of the Stock, but under no circumstances
         is the Administrative Agent obligated by the terms of this Agreement to
         exercise such rights, and (ii) the Borrower hereby appoints the
         Administrative Agent, which appointment shall be effective on the
         fifteenth (15th) day following the giving of notice by the
         Administrative Agent as provided in the foregoing Section 9(a)(i), the
         Borrower's true and lawful attorney-in-fact and IRREVOCABLE PROXY to
         vote the Stock in any manner the Administrative Agent deems advisable
         for or against all matters submitted or which may be submitted to a
         vote of shareholders. The power-of-attorney granted hereby is coupled
         with an interest and shall be irrevocable.

                  (b)   For so long as the Borrower shall have the right to vote
         the Stock, the Borrower covenants and agrees that it will not, without
         the prior written consent of the Administrative Agent, vote or take any
         consensual action with respect to the Stock which would constitute an
         Event of Default.

         10.      Notices.  All notices and other communications required or 
permitted hereunder shall be in writing and shall be given in the manner and at
the addresses set forth in Section 11.1 of the Loan Agreement.

         11.   Binding Agreement. The provisions of this Agreement shall be
construed and interpreted, and all rights and obligations of the parties hereto
determined, in accordance with the internal laws of the State of New York
applicable to contracts made and to be performed in the State of New York. This
Agreement, together with all documents referred to herein, constitutes the
entire agreement between the parties with respect to the matters addressed
herein and may not be modified except by a writing executed by the
Administrative Agent and the Borrower and delivered by the Administrative Agent
to the Borrower.

         12.   Severability. If any paragraph or part thereof shall for any 
reason be held or adjudged to be invalid, illegal or unenforceable by any court
of competent jurisdiction, such paragraph or part thereof so adjudicated
invalid, illegal or unenforceable shall be deemed separate, distinct and
independent, and the remainder of this Agreement shall remain in full force and
effect and shall not be affected by such holding or adjudication.

         13.   FCC Compliance. Notwithstanding anything herein which may be
construed to the contrary, no action shall be taken by the Administrative Agent
which may require the consent or approval of the FCC or other governmental
authority, and the proxy granted in Section 9(a) shall not become effective,
unless and until all requirements of the Communications Act or other Applicable
Law requiring the consent to or approval of such action by the FCC or other
governmental authority have been satisfied. The Borrower covenants that,
following and during the continuation of an Event of Default, upon request of
the Administrative Agent, it will cause to be filed such applications and take
such other action as may be requested by the Administrative Agent to obtain
consent or approval of the FCC or other governmental authority to any action
contemplated by this Agreement and to give effect to the security interest of
the Administrative Agent, including, without limitation, the execution of an
application for consent by the FCC or other governmental authority to an
assignment or transfer involving a change in ownership or control pursuant to
the provisions of the Communications Act or other Applicable Law.

         14.   Care and Custody of Collateral. The Administrative Agent shall be
deemed to have exercised reasonable care in the custody and preservation of the
Collateral if it takes such action for that purpose as is customary in the
banking industry or as the Pledgor shall request in writing, but failure of the
Administrative Agent to comply with any such request shall not of itself be
deemed a failure to exercise reasonable care, and no failure of the
Administrative Agent to preserve or protect any rights with respect to the
Collateral against prior parties, or to do any act not customary in the banking
industry with respect to preservation of the Collateral not so requested by the


                                      - 7 -
<PAGE>   113
Pledgor, shall be deemed a failure to exercise reasonable care in the custody or
preservation of the Collateral.

         15.   Counterparts.  This Agreement may be executed in multiple 
counterparts, each of which shall be deemed to be an original, but all such 
separate counterparts shall together constitute but one and the same instrument.

         16.   Administrative Agent. Each reference herein to any right granted
to, benefit conferred upon or power exercisable by the "Administrative Agent"
shall be a reference to the Administrative Agent for the benefit of the Managing
Agents, the Documentation Agent, the Syndication Agent, and all the Banks, and
each action taken or right exercised hereunder shall be deemed to have been so
taken or exercised by the Administrative Agent for the benefit of and on behalf
of the Managing Agents, the Documentation Agent, the Syndication Agent and all
the Banks.

reasonably require for the purpose of perfecting or protecting the rights of the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent hereunder or otherwise giving effect to this Agreement,
all promptly upon request therefor.

warrants to the Banks, the Syndication Agent, the


                                       -4-
<PAGE>   119
Documentation Agent, the Managing Agents and the Administrative Agent that:

                  (a)  Exhibit A attached hereto and incorporated herein by this
         reference sets forth a complete and accurate list of the Contracts in
         effect on the date hereof which provide for aggregate payments over the
         life of each such Contract in excess of $250,000.00 or which are
         otherwise material to the Borrower, and the Borrower will furnish
         copies thereof to the Banks, the Syndication Agent, the Documentation
         Agent, the Managing Agents and the Administrative Agent upon the
         request of the Administrative Agent;

                  (b)  Exhibit B attached hereto and incorporated herein by this

         providing for aggregate payments over the life of any single Lease in
         excess of $250,000.00, to which the Borrower is party in effect on the
         date hereof, and the Borrower will furnish copies thereof to the Banks,
         the Syndication Agent, the Documentation Agent, the Managing Agents and
         the Administrative Agent upon the request of the Administrative Agent;

         3.       Representations and Warranties Concerning Collateral. The 
Borrower further represents and warrants to the Banks, the Syndication Agent,
the Documentation Agent, the Managing Agents and the Administrative Agent that
(a) the Security Interest in the Collateral granted hereunder shall constitute
at all times a valid, perfected first priority security interest (subject only
to Permitted Liens), vested in the Administrative Agent, in and upon the
Collateral, free of any Liens except for Permitted Liens, (b) the location of
the Inventory comprising at least ninety (90%) percent by value of the aggregate
value of all Inventory existing at any time is as set forth in Schedule 1(a)
hereto and the location of Equipment and Furniture and Fixtures is set forth on
Schedule 1(b) hereto which includes all office, transmitter and antenna sites,
(c) except as set forth in Schedule 1(c) hereto, none of the Accounts are
represented by promissory notes, or other documents or instruments, and (d) any
Collateral that includes obligations of consumers shall comply in all respects
with all applicable consumer credit laws. The Borrower shall take or cause to be
taken such acts and actions as shall be necessary or appropriate to assure that
the Security Interest in the Collateral shall not become subordinate or junior
to the security interests, liens or claims of any other Person, and that the
Collateral shall not otherwise be or become subject to any Lien, except for
Permitted Liens.

<PAGE>   120
         4.   Location of Books and Records. The Borrower further represents and
warrants that it now keeps all of its records concerning its Accounts,
Contracts, Leases, Other Contracts, and Intangibles at its chief executive
office, which is the address set forth with respect to the Borrower in Section 
11.1 of the Loan Agreement. The Borrower covenants and agrees that it shall not
keep any of such records at any other address except as set forth on Schedule
1(d) attached hereto, as supplemented from time to time, unless written notice
thereof is given to the Administrative Agent at least thirty (30) days prior to
the relocation to any new address for the keeping of such records. The Borrower
further agrees that it shall promptly advise the Administrative Agent, in
writing making reference to this Section 4 of any change in the location of the
place where it keeps Inventory and Equipment comprising five percent (5%) or
more by value of the aggregate value of Inventory and Equipment of the Borrower
or of any relocation of its chief executive office. Within thirty (30) days
following the end of each fiscal year of the Borrower, and at such other time as
the Administrative Agent shall request, the Borrower will deliver to the
Administrative Agent a current list of the office, transmitter and antenna sites
of the Borrower.

         5.   Collateral Not Fixtures.  The parties intend that, to the extent 
permitted by Applicable Law, the Collateral shall remain personal property
irrespective of the manner of its attachment or affixation to realty.

         6.   Covenants Regarding Collateral. Any and all injury to, or loss or
destruction of, the Collateral shall be at the Borrower's risk, and shall not
release the Borrower from its obligations hereunder. The Borrower agrees not to
sell, transfer, assign, dispose of, mortgage, grant a security interest in, or
encumber any of the Collateral except as permitted under the Loan Agreement. The
Borrower agrees to maintain in force such insurance with respect to the
Collateral as is required under the Loan Agreement. The Borrower agrees to pay
all required taxes, liens, and assessments upon the Collateral, its use or
operation, as required under the Loan Agreement. The Borrower further agrees
that the Administrative Agent may, but shall in no event be obligated to, upon
prior written notice to the Borrower, insure any of the Collateral in such form
and amount as the Administrative Agent may deem necessary or desirable if the
Borrower fails to obtain and maintain in effect insurance as required by the
Loan Agreement, and that the Administrative Agent may pay or discharge any taxes
or Liens (which are not Permitted Liens) on any of the Collateral, and the
Borrower agrees to pay any such sum so expended by the Administrative Agent,
with interest at the Default Rate, and such amounts shall be deemed to be a part
of the Obligations secured by the Collateral under the terms of this Agreement.

<PAGE>   121
         7.    Covenants Regarding Contracts, Other Contracts and Leases. The
Borrower shall (i) fulfill, perform and observe each and every material
condition and covenant contained in any of the Contracts, the Other Contracts or
the Leases, (ii) give prompt notice to the Administrative Agent of any claim
alleging loss or damage in excess of $250,000.00 resulting from a material
default under any Contract, Other Contract or Lease given to the Borrower or by
the Borrower, (iii) at the sole cost and expense of the Borrower, enforce the
performance and observance of each and every material covenant and condition of
the Contracts, the Other Contracts and the Leases in a manner consistent with
industry practice, and (iv) appear in and defend any action growing out of or in
any manner connected with any material Contract, Other Contract or Lease. None
of the Banks, the Syndication Agent, the Documentation Agent, the Managing
Agents or the Administrative Agent shall have or acquire any liability or
obligation under the Contracts, the Other Contracts or the Leases, by reason of
this Agreement, nor shall any of them have any obligation to perform or take any
action in respect thereof. The rights and interests granted to the
Administrative Agent hereunder include all of the Borrower's rights and title
(i) to modify the Contracts, the Other Contracts and the Leases, (ii) to
terminate the Contracts, the Other Contracts and the Leases, and (iii) to waive
or release the performance or observance of any obligation or condition of the
Contracts, the Other Contracts and the Leases; provided, however, that the
Borrower shall have the right to exercise these rights in a fashion consistent
with this Agreement and the Loan Agreement prior to any Event of Default and
that these rights shall not be exercised by the Administrative Agent prior to an
Event of Default. To the extent that the Borrower's rights under any Contract,
Lease or Other Contract may not be assigned as collateral security to the
Administrative Agent without the consent of another Person which has not been
obtained, this Agreement shall not constitute an assignment or an agreement to
assign the same if an attempted assignment would constitute a breach thereof or
be unlawful, and the Borrower, at its expense, shall use its best efforts to
obtain any such required consents as promptly as possible. If any such consent
shall not be obtained or if any attempted assignment would be ineffective or
would impair the Administrative Agent's rights under the Contract, Leases or
Other Contracts in question so that the Administrative Agent would not in effect
acquire the benefit of all such rights intended to be provided hereunder, the
Borrower, to the maximum extent permitted by law, shall act after the date
hereof as the Administrative Agent's agent in order to obtain for it the
benefits thereunder and shall cooperate, to the maximum extent permitted by law,
with the Administrative Agent in any other reasonable arrangement designed to
provide such benefits to the Administrative Agent.

         8.    Remedies. Upon the occurrence and during the continuation of an
Event of Default the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents and the Administrative Agent shall have such rights and remedies
as are set forth in the Loan Agreement and herein, all the rights, powers and
privileges of a secured party under the UCC of the State of New York and any
other applicable jurisdiction, and all other rights and remedies available to
the Banks, the Syndication Agent, the Documentation Agent, the Managing Agents
and the Administrative Agent, or any of them, at law or in equity. The Borrower
covenants and agrees that any notification of intended disposition of any
Collateral, if such notice is required by law, shall be deemed reasonably and
properly given if given in the manner provided for in paragraph 19 hereof at
least ten (10) days prior to such disposition. Upon the occurrence and during
the continuation of an Event of Default, the Administrative Agent shall have the
right to the appointment of a receiver for the properties and assets of the
Borrower, and the Borrower hereby consents to such right and to such appointment
and hereby waives any objection the Borrower may have thereto and hereby waives
the right to have a bond or other security posted by the Administrative Agent or
any other Person in connection therewith. The Borrower agrees, after the
occurrence and during the continuation of an Event of Default, to take any
actions that the Administrative Agent may reasonably request in order to enable
the Administrative Agent to obtain and enjoy the full rights and benefits
granted to the Administrative Agent under this Agreement and the other Loan
Documents. Without limiting the generality of the foregoing, upon the occurrence
and during the continuation of an Event of Default, the Borrower shall, at the
Borrower's cost and expense, use its best efforts to assist in obtaining all
approvals of the FCC which are then required by law for or in connection with
any action or transaction contemplated by this Agreement or Article 9 of the UCC
as in effect in any applicable jurisdiction, and, at the Administrative Agent's
request, promptly prepare, sign and file with the FCC the assignor's or
transferor's portion of any application or applications for consent to the
assignment of the Licenses or transfer of control thereof necessary or
appropriate under the FCC's rules for approval of any sale or transfer of the
Licenses in connection with the Administrative Agent's exercise of remedies
under this Agreement. The Administrative Agent shall have the right, in
connection with the issuance of any order for relief in a bankruptcy proceeding,
to petition the bankruptcy court for the transfer of control or assignment of
the Licenses to a receiver, trustee, transferee, or similar official or to any
purchaser of the Collateral pursuant to any public or private sale, foreclosure
or other exercise of remedies available to the Administrative Agent, all as
permitted by Applicable Law. All amounts realized or collected through the
exercise of remedies


                                       -8-
<PAGE>   123
hereunder shall be applied to the Obligations as provided in the Loan Agreement.

         9.    Notification of Account Debtors. Upon the occurrence and during 
the continuation of an Event of Default, the Administrative Agent may notify the
account debtors that all payments with respect to Accounts, Contracts, Leases,
Other Contracts and Miscellaneous Items are to be paid directly to the
Administrative Agent and any amount thereafter paid to the Borrower shall be
received in trust by Borrower for the benefit of the Administrative Agent and
segregated from other funds of the Borrower and paid over to the Administrative
Agent in the form received (together with any necessary endorsements).

         10.   Remedies of Administrative Agent. Upon the occurrence and during
the continuation of an Event of Default, and after written notice to the
Borrower, the Administrative Agent or its designee may proceed to perform any
and all of the obligations of the Borrower contained in any of the Contracts,
Other Contracts or Leases and exercise any and all rights of the Borrower
therein contained as fully as the Borrower itself could. The Borrower hereby
appoints the Administrative Agent its attorney-in-fact, with power of
substitution, to take such action, execute such documents, and perform such work
as the Administrative Agent may deem appropriate in exercise of the rights and
remedies granted the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents and the Administrative Agent, or any of them, herein or in any
other Loan Document. The powers herein granted shall include, but not be limited
to, powers to: (i) sue on the Contracts, the Other Contracts or the Leases; (ii)
seek all governmental approvals (other than FCC approvals) required for the
operation of the business of the Borrower; (iii) modify or terminate the
Contracts, the Other Contracts and the Leases; and (iv) waive or release the
performance or observance of any obligation under any of the Contracts, Other
Contracts or Leases. The power of attorney granted herein is coupled with an
interest and shall be irrevocable.

         11.   Additional Remedies. Upon the occurrence and during the
continuation of an Event of Default, should the Borrower fail to perform or
observe any covenant or comply with any condition contained in any of the
Contracts, the Other Contracts or the Leases, then the Administrative Agent may,
but without obligation to do so and without releasing the Borrower from its
obligation to do so, and after written notice to the Borrower, perform such
covenant or condition and, to the extent that the Administrative Agent shall
incur any costs or pay any expenses in connection therewith, including any
reasonable costs or expenses of litigation associated therewith, such costs,
expenses or payments shall be included in the Obligations secured hereby and
shall bear interest from the payment of such costs or expenses by the


                                       -9-
<PAGE>   124
Administrative Agent at the Default Rate. Neither the Administrative Agent nor
any Bank shall be obliged to perform or discharge any obligation of the Borrower
under any of the Contracts, the Other Contracts or the Leases, and, except as
may result from the gross negligence or willful misconduct of the Person seeking
indemnification, the Borrower agrees to indemnify and hold the Administrative
Agent and each Bank harmless against any and all liability, loss or damage which
any such Person may incur under any of the Contracts, the Other Contracts or the
Leases or under or by reason of this Agreement, and any and all claims and
demands whatsoever which may be asserted against the Borrower by reason of an
act of the Administrative Agent or any Bank under any of the terms of this
Agreement or under the Contracts, the Other Contracts or the Leases.

         12.   Administrative Agent May Collect Accounts. The Borrower hereby
further appoints the Administrative Agent as its attorney-in-fact, with power of
substitution, with authority, upon the occurrence and during the continuation of
an Event of Default, to collect all Accounts and Miscellaneous Items, to endorse
the name of the Borrower on any note, acceptance, check, draft, money order or
other evidence of debt or of payment which constitutes a portion of the
Collateral and which may come into the possession of the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent, or any of them, and generally to do such other things and acts in the
name of the Borrower with respect to the Collateral as are necessary or
appropriate to protect or enforce the rights hereunder of the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent. The Borrower further authorizes the Administrative Agent,
effective upon the occurrence and during the continuation of an Event of
Default, to compromise and settle or to sell, assign or transfer or to ask,
collect, receive or issue any and all claims possessed by the Borrower which
constitute a portion of the Collateral, all in the name of the Borrower. After
deducting all reasonable expenses and charges (including the Administrative
Agent's reasonable attorneys' fees) of retaking, keeping, storing and selling
the Collateral, the Administrative Agent may apply the proceeds in payment of
any of the Obligations in the order of application set forth in the Loan
Agreement. The power of attorney granted herein is coupled with an interest and
shall be irrevocable. The Borrower agrees that if steps are taken by the
Administrative Agent to enforce its rights hereunder, or to realize upon any of
the Collateral, the Borrower shall pay to the Administrative Agent the amount of
the Administrative Agent's costs, including reasonable attorneys' fees, and the
Borrower's obligation to pay such amounts shall be deemed to be a part of the
Obligations secured hereunder. Upon the occurrence and during the continuation
of an Event of Default, the Borrower shall mark conspicuously its Accounts and
chattel paper with a


                                      -10-
<PAGE>   125
legend indicating such Collateral is subject to the security interests created
hereby and at the request of the Administrative Agent deliver to the
Administrative Agent each promissory note, chattel paper, instrument or security
constituting Collateral, duly endorsed or accompanied by executed instruments of
transfer, in form and substance satisfactory to the Administrative Agent and
shall segregate all proceeds of any Collateral from other assets of the
Borrower.

         13.   Indemnification. The Borrower shall indemnify and hold harmless 
the Administrative Agent, each Bank, and any other Person acting hereunder for
all losses, costs, damages, fees and expenses whatsoever associated with the
exercise of the rights granted hereunder and powers of attorney granted herein
and shall release the Administrative Agent, each Bank, and any other Person
acting hereunder from all liability whatsoever for the exercise of the foregoing
rights and powers of attorney and all actions taken pursuant thereto, except, in
either event, in the case of gross negligence or willful misconduct by the
Person seeking indemnification.

         14.   Remedies Cumulative. The Borrower agrees that the rights of the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, or any of them, under this Agreement, the Loan
Agreement, any other Loan Document or any other contract or agreement now or
hereafter in existence among the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents and the Administrative Agent and the Borrower or any
Subsidiary of the Borrower and the other obligors thereunder, or any of them,
shall be cumulative, and that the Administrative Agent and each Bank may from
time to time exercise such rights and such remedies as such Person or Persons
may have thereunder and under the laws of the United States or any state, as
applicable, in the manner and at the time that such Person or Persons in its or
their sole discretion desire, subject to the terms of such agreements. The
Borrower further expressly agrees that the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent shall in
no event be under any obligation to resort to any Collateral secured hereby
prior to exercising any other rights that the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, may have against the Borrower or any Subsidiary of the Borrower or any of
their respective properties, nor shall the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, be obliged to resort to any other collateral or security for the
Obligations, other than the Collateral, prior to any exercise of the
Administrative Agent's rights against the Borrower and its property hereunder.


                                      -11-
<PAGE>   126
         15.  Obligations Commercial in Nature. The Borrower hereby acknowledges
that the Obligations arose out of a commercial transaction, and agrees that if
an Event of Default shall occur and be continuing, the Administrative Agent
shall have the right to immediate possession without notice or a hearing, and
hereby voluntarily, knowingly and intelligently waives any and all rights it may
have to any notice and posting of a bond by the Banks, the Syndication Agent,
the Documentation Agent, the Managing Agents and the Administrative Agent, or
any of them, prior to seizure by the Administrative Agent or any of its
transferees, assigns or successors in interest, of the Collateral or any portion
thereof.

         16.  Amendments and Waivers. No amendment, modification, waiver,
transfer or renewal, extension, assignment or termination of this Agreement or
of the Loan Agreement or of any other Loan Document, or of any instrument or
document executed and delivered by the Borrower or any other obligor to the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, or any of them, nor additional advances made by the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, or any of them, to the Borrower, nor the taking of
further security, nor the retaking or re-delivery or release of the Collateral
to the Borrower or any other collateral or guaranty by the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, nor any lack of validity or enforceability
of any Loan Document or any term thereof nor any other act of the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, shall release the Borrower from any
Obligation, except a release or discharge executed in writing by the
Administrative Agent in accordance with the Loan Agreement with respect to such
Obligation or upon full payment and satisfaction of all Obligations and
termination of the Commitments. None of the Administrative Agent, the Managing
Agents, the Documentation Agent, the Syndication Agent, nor any Bank shall by
any act, delay, omission or otherwise, be deemed to have waived any of its or
their rights or remedies hereunder, unless such waiver is in writing and signed
by the Administrative Agent in accordance with the Loan Agreement and then only
to the extent therein set forth. A waiver by the Banks, the Syndication Agent,
the Documentation Agent, the Managing Agents and the Administrative Agent, or
any of them, of any right or remedy on any occasion shall not be construed as a
bar to the exercise of any such right or remedy which any such Person would
otherwise have had on any other occasion.

         17.  Assignment.  The Borrower hereby agrees that this Agreement or the
rights hereunder may, in the discretion of the Banks, the Syndication Agent, the
Documentation Agent, the


                                      -12-
<PAGE>   127
Managing Agents and the Administrative Agent or any of them, as applicable, be
assigned in whole or in part in connection with any assignment of the Loan
Agreement or the Indebtedness evidenced thereby, as permitted thereunder. In the
event this Agreement or the rights hereunder are so assigned by any of the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, the terms "Banks," "Syndication Agent," "Documentation
Agent," "Managing Agents" or "Administrative Agent" wherever used herein shall
be deemed, as applicable, to refer to and include any such assignee.

         18.   Successors and Assigns.  This Agreement shall apply to and bind 
the respective successors and permitted assigns of the Borrower and inure to the
benefit of the successors and permitted assigns of the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent.

         19.   Notices.  All notices and other communications required or 
permitted hereunder shall be in writing and shall be given in the manner
prescribed in Section 11.1 of the Loan Agreement.

         20.   Governing Law. THE PROVISIONS OF THIS AGREEMENT SHALL BE 
CONSTRUED AND INTERPRETED, AND ALL RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO
DETERMINED, IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK
APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK. This
Agreement, together with all documents referred to herein, constitutes the
entire agreement among the Borrower, the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent with
respect to the matters addressed herein and may not be modified except by a
writing executed by the Administrative Agent and delivered to the Borrower.

         21.   Severability. If any paragraph or part thereof of this Agreement
shall for any reason be held or adjudged to be invalid, illegal or unenforceable
by any court of competent jurisdiction, such paragraph or part thereof so
adjudicated invalid, illegal or unenforceable shall be deemed separate, distinct
and independent, and the remainder of this Agreement shall remain in full force
and effect and shall not be affected by such holding or adjudication.

         22.   FCC Consent. Notwithstanding anything herein which may be 
construed to the contrary, no action shall be taken by the Administrative Agent
with respect to the Licenses unless and until all requirements of Applicable
Law, including, without limitation, any required approval under the
Communications Act, requiring the consent to or approval of such action by the
FCC or any governmental or other authority, have been satisfied. The Borrower
covenants that upon request of the Administrative Agent it will cause to be
filed such applications and take such other


                                      -13-
<PAGE>   128
action as may be requested by the Administrative Agent to obtain the consent or
approval of the FCC or any governmental or other authority which has granted any
License to the Borrower to any action contemplated by this Agreement and to give
effect to the Security Interest of the Administrative Agent, including, without
limitation, the execution of an application for consent by the FCC to an
assignment or transfer involving a change in ownership or control pursuant to
the provisions of the Communications Act.

         23.   Counterparts.  This Agreement may be executed in any number of 
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

         24.   Changes in Applicable Law. The parties acknowledge their intent
that, upon the occurrence and during the continuation of an Event of Default,
the Administrative Agent shall receive, to the fullest extent permitted by
Applicable Law and governmental policy (including, without limitation, the
rules, regulations and policies of the FCC), all rights necessary or desirable
to obtain, use or sell the Collateral and to exercise all remedies available to
it under this Agreement, the UCC as in effect in any applicable jurisdiction, or
other Applicable Law. The parties further acknowledge and agree that, in the
event of changes in law or governmental policy occurring subsequent to the date
hereof that affect in any manner the Administrative Agent's rights of access to,
or use or sale of, the Collateral, or the procedures necessary to enable the
Administrative Agent to obtain such rights of access, use or sale, the
Administrative Agent and the Borrower shall amend this Agreement in such manner
as the Administrative Agent shall reasonably request in order to provide the
Administrative Agent such rights to the greatest extent possible consistent with
Applicable Law and governmental policy.

         25.   Administrative Agent. Each reference herein to any right granted
to, benefit conferred upon or power exercisable by the "Administrative Agent"
shall be a reference to the Administrative Agent for the benefit of the Managing
Agents, the Documentation Agent, the Syndication Agent and all the Banks, and
each action taken or right exercised hereunder shall be deemed to have been so
taken or exercised by the Administrative Agent for the benefit of and on behalf
of the Managing Agents, the Documentation Agent, the Syndication Agent and all
the Banks.

                                    EXHIBIT C

                   FORM OF CERTIFICATE OF FINANCIAL CONDITION

         Metrocall, Inc., a Delaware corporation (the "Borrower"), in connection
with that certain Amended and Restated Loan Agreement (as amended, restated,
replaced or otherwise modified from time to time, the "Loan Agreement") of even
date herewith among the Borrower, certain financial institutions signatories to
the Loan Agreement (collectively, the "Banks"), The First National Bank of
Boston, as syndication agent (in such capacity, the "Syndication Agent"), The
Toronto-Dominion Bank, as documentation agent (in such capacity, the
"Documentation Agent"), The Toronto-Dominion Bank and The First National Bank of
Boston, as managing agents for the Banks (collectively, in such capacity, the
"Managing Agents"), and Toronto Dominion (Texas), Inc., as administrative agent
for the Banks, the Syndication Agent, the Documentation Agent and the Managing
Agents (the "Administrative Agent"), pursuant to which the Banks have agreed to
make loans to the Borrower (the "Loans"), hereby certifies to each of the
foregoing that:

         1.   The financial statements and all other documents relating to the
Borrower's present or projected future financial condition (together with
similar information relating to the Restricted Subsidiaries of the Borrower,
hereinafter referred to collectively as the "Subsidiaries") provided to the
Administrative Agent, the Managing Agents, the Documentation Agent, the
Syndication Agent and the Banks in connection with the Loan Agreement, have been
prepared by the undersigned or under the supervision of the undersigned, with
due diligence and in full awareness of the reliance of the Banks on the
information contained therein in reaching their decision to make the Loans. Such
financial statements have been prepared in accordance with GAAP.

         2.   The Borrower, as a result of the Loans and any obligations 
incurred in connection therewith and the other transactions contemplated by the
Loan Agreement, believes that the Borrower has not incurred and will not incur
debts beyond its ability to satisfy them as they mature, and will have a
positive operating cash flow after paying all of its anticipated indebtedness
when due, including the obligations due to the Banks under the Loan Agreement.

         3. After giving effect to the Loans and the obligations incurred in
connection therewith and the other transactions contemplated by the Loan
Agreement and the Loan Documents, the Borrower (on a consolidated basis with its
Subsidiaries) anticipates that it will have sufficient proceeds from its cash
<PAGE>   131
flow to pay cash interest expense and current maturities of long-term
Indebtedness when due. The cash flow of the Borrower is expected to be
sufficient to provide the cash needed to repay existing Indebtedness as such
matures.

         4.  Immediately after giving effect to the transactions contemplated by
the Loan Agreement and the other Loan Documents, the fair saleable value of the
assets of the Borrower and its Subsidiaries (on a consolidated basis) will
exceed the aggregate amount of all Indebtedness then outstanding of the Borrower
and its Subsidiaries (on a consolidated basis).

         5.  Based on the present and anticipated needs for capital of the
businesses conducted, or anticipated to be conducted in the future by the
Borrower and its Subsidiaries, and after giving effect to the Loans, the
Borrower (on a consolidated basis with its Subsidiaries) will not be left with
unreasonably small capital to finance the needs and anticipated needs of such
businesses.

         Capitalized terms used herein and not otherwise defined are used as
defined in the Loan Agreement.

assigns, called the "Bank"), at such place as is designated in or pursuant to
the Loan Agreement (as hereinafter defined), the principal sum of
_________________ AND ____ /100 DOLLARS ($____________) of United States funds,
or, if less, so much thereof as may from time to time be advanced by the Bank to
the Borrower and is outstanding hereunder, plus interest as hereinafter
provided. Such Advances may be endorsed from time to time on the grid attached
hereto, but the failure to make such notations (or any error in such notation)
shall not effect the obligation of the Borrower to repay unpaid principal and
interest hereunder.

         Except as otherwise defined or limited herein, capitalized terms used
herein shall have the meanings ascribed to them in that certain Amended and
Restated Loan Agreement dated as of September 20, 1996 (as amended, restated,
replaced or otherwise modified from time to time, the "Loan Agreement") by and
among the Borrower, the Bank, the other financial institutions which are from
time to time party thereto, The First National Bank of Boston, as syndication
agent (in such capacity, the "Syndication Agent"), The Toronto-Dominion Bank, as
documentation agent (in such capacity, the "Documentation Agent"), The
Toronto-Dominion Bank and The First National Bank of Boston, as managing agents
for the Banks (collectively, in such capacity, the "Managing Agents"), and
Toronto Dominion (Texas), Inc. as administrative agent for the Banks, the
Syndication Agent, the Documentation Agent and the Managing Agents (the
"Administrative Agent").

         The principal amount of this Note shall be paid in such amounts and at
such times as are set forth herein and in Sections 2.5 and 2.7 of the Loan
Agreement and as otherwise provided in the Loan Agreement. A final payment of
all principal amounts and other Obligations then outstanding hereunder shall be
due and payable in full on the Maturity Date.

         The Borrower shall be entitled to borrow, repay and reborrow hereunder
pursuant to the terms and conditions of the Loan Agreement. Prepayment of the
principal amount hereof may be made only as provided in the Loan Agreement. The
principal amount of each Eurodollar Advance shall be repaid on its Payment Date.
<PAGE>   134
         The Borrower hereby promises to pay interest on the unpaid principal
amount of the Loans outstanding hereunder as provided in the Loan Agreement.
Interest under this Note shall also be due and payable when this Note shall
become due (whether at maturity, by reason of acceleration or otherwise).
Overdue principal and, to the extent permitted by Applicable Law, overdue
interest, shall bear interest at the Default Rate as provided in the Loan
Agreement.

         No provision of the Loan Agreement or this Note shall require the
payment or permit the collection of interest in excess of that permitted by
Applicable Law. If any excess amount of interest in such respect is provided
for, or shall be adjudicated to be so provided in connection with the Loans
outstanding hereunder, the provisions of this paragraph shall govern and
prevail, and neither the Borrower nor any sureties, guarantors, endorsers,
successors or assigns of the Borrower shall be obligated to pay the excess
amount of such interest or any other excess sum paid for the use, forbearance,
or detention of sums loaned pursuant hereto. In the event the Borrower ever
pays, or the Bank ever receives, collects or applies as interest, any such sum,
such amount which would be in excess of the maximum amount permitted by
Applicable Law shall be applied as a payment in the reduction of the principal,
unless the Borrower shall notify the Bank in writing that it elects to have such
excess returned forthwith; and, if the principal has been paid in full, any
remaining excess shall forthwith be returned to the Borrower. Because of the
variable nature of the rates of interest applicable to the Loans evidenced by
this Note, the total interest that will accrue hereon cannot be determined in
advance. Neither the Borrower nor the Bank intends for the Bank to contract for,
charge or receive usurious interest and to prevent such an occurrence, any
agreements which may now or hereafter be in effect between the Borrower and the
Bank regarding the payment of fees to the Bank are hereby limited by the
provisions of this paragraph. To the extent not prohibited by Applicable Law,
determination of the legal maximum amount of interest shall at all times be made
by amortizing, prorating, and allocating all interest at any time contracted
for, charged or received from the Borrower in connection with the portion of the
Loans outstanding hereunder until the Maturity Date, so that the actual rate of
interest on account of the Loans outstanding hereunder does not exceed the
maximum amount permitted under Applicable Law.

         All parties now or hereafter liable with respect to this Note, whether
the Borrower, any guarantor, surety, endorser or any other person or entities,
hereby waive presentment for payment, demand, notice of non payment or dishonor,
protest and notice of protest.

               1. Further Assurances. Each Subsidiary hereby authorizes the
Administrative Agent to file such financing statements and such other documents
as the Administrative Agent may deem necessary or desirable to protect or
perfect the interest of the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents, and the Administrative Agent in the Collateral, and
each Subsidiary further irrevocably appoints the Administrative Agent as such
Subsidiary's attorney-in-fact, with a power of attorney to execute on behalf of
such Subsidiary such UCC financing statement forms and other documents as the
Administrative Agent may from time to time reasonably deem necessary or
desirable to protect or perfect such interest in the Collateral and to endorse
in such Subsidiary's name and on its behalf any payments received by such
Subsidiary as provided in Section 9 below. Such power of attorney is coupled
with an interest and shall be irrevocable. In addition, each Subsidiary agrees,
at its expense, to do, execute and deliver or cause to be done, executed and
delivered all such further acts, documents and things as the Administrative
Agent may reasonably require for the purpose of perfecting or protecting the
rights of the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents, and the Administrative Agent hereunder or otherwise giving

               2. Representations and Warranties. Each Subsidiary represents and
warrants to the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents, and the Administrative Agent that:

                    (a) the execution and delivery of this Agreement and the
               fulfillment of the terms hereof will not result in a breach of
               any of the terms or provisions of, or constitute a default under,
               such Subsidiary's Articles of Incorporation, Certificate of
               Incorporation, By-Laws or other organizational documents, as
               applicable, as currently in effect, or any order, rule or
               regulation applicable to such Subsidiary of any court or of any
               federal or state regulatory body or administrative agency or
               other governmental body having jurisdiction over such Subsidiary,
               or result in the termination or cancellation or breach of any
               indenture, mortgage, deed of trust, deed to secure debt, lease or
               other agreement or instrument to which such Subsidiary is a party
               or by which it is bound or affected;

                    (b) such Subsidiary has taken all necessary corporate
               action, as applicable, to authorize the execution and delivery of
               this Agreement, and this Agreement, when executed and delivered,
               is and will be the valid and binding obligation of such
               Subsidiary enforceable in accordance with its terms, subject only
               to the following qualifications:


                                       -5-
<PAGE>   163
                         (i) certain equitable remedies are discretionary and,
                    in particular, may not be available where damages are
                    considered an adequate remedy at law,

                         (ii) enforcement may be limited by bankruptcy,
                    insolvency, liquidation, reorganization, reconstruction and
                    other similar laws affecting enforcement of creditors'
                    rights generally (insofar as any such law relates to the
                    bankruptcy, insolvency or similar event of such Subsidiary),
                    and

                         (iii) enforcement as to the Licenses is limited by FCC
                    and state rules and regulations restricting the transfer of
                    such Licenses.

                    (c) Exhibit A attached hereto and incorporated herein by
               this reference sets forth a complete and accurate list of the
               Contracts in effect on the date hereof which provide for
               aggregate payments over the life of each such Contract in excess
               of $250,000.00 or which are otherwise material to such
               Subsidiary, and such Subsidiary will furnish copies thereof to
               the Banks, the Syndication Agent, the Documentation Agent, the
               Managing Agents, and the Administrative Agent upon the request of
               the Administrative Agent;

                    (d) Exhibit B attached hereto and incorporated herein by
               this reference sets forth a complete and accurate list of all
               Leases providing for aggregate payments over the life of any
               single Lease in excess of $250,000.00, to which such Subsidiary
               is a party in effect on the date hereof, and such Subsidiary will
               furnish copies thereof to the Banks, the Syndication Agent, the
               Documentation Agent, the Managing Agents, and the Administrative
               Agent upon the request of the Administrative Agent; and

                    (e) Exhibit C attached hereto and incorporated herein by
               this reference sets forth a complete and accurate list of the
               Licenses in effect on the date hereof.

               3. Representations and Warranties Concerning Collateral. Each
Subsidiary further represents and warrants to the Banks, the Syndication Agent,
the Documentation Agent, the Managing Agents, and the Administrative Agent that
(a) the Security Interest in the Collateral granted hereunder shall constitute
at all times a valid, perfected first priority security interest (subject only
to Permitted Liens), vested in the Administrative Agent, in and upon the
Collateral, free of any Liens except for Permitted Liens; (b) the location of
the Inventory comprising at least ninety (90%) percent by value of the aggregate
value of all Inventory existing at any time is as set forth on Schedule 1(a)


                                       -6-
<PAGE>   164
hereto and the location of Equipment and Furniture and Fixtures is set forth on
Schedule 1(b) hereto which includes all office, transmitter and antenna sites;
(c) none of the Accounts are represented by promissory notes, or other documents
or instruments; and (d) any Collateral that includes obligations of consumers
shall comply in all respects with all applicable consumer credit laws. Each
Subsidiary shall take or cause to be taken such acts and actions as shall be
necessary or appropriate to assure that the Security Interest in the Collateral
shall not become subordinate or junior to the security interests, liens or
claims of any other Person, and that the Collateral shall not otherwise be or
become subject to any Lien, except for Permitted Liens.

               4. Location of Books and Records. Each Subsidiary further
represents and warrants that it now keeps all of its records concerning its
Accounts, Contracts, Leases, Other Contracts, and Intangibles at its chief
executive office, at the address listed on Exhibit D hereto, except as otherwise
disclosed on Exhibit D hereto. Each Subsidiary covenants and agrees that it
shall not keep any of such records at any other address except as set forth on
Exhibit D attached hereto, as supplemented from time to time, unless written
notice thereof is given to the Administrative Agent at least thirty (30) days
prior to the relocation to any new address for the keeping of such records. Each
Subsidiary further agrees that it shall promptly advise the Administrative Agent
in writing, making reference to this Section 4 of this Agreement, of any change
in the location of the place where it keeps Inventory and Equipment comprising
five percent (5%) or more by value of the aggregate value of Inventory and
Equipment of the Subsidiary or of any relocation of its chief executive office.
Within thirty (30) days following the end of each fiscal year of each
Subsidiary, and at such other times as the Administrative Agent shall request,
each Subsidiary will deliver to the Administrative Agent a current list of the
office, transmitter and antenna sites of the Subsidiary.

               5. Collateral Not Fixtures. The parties intend that, to the
extent permitted by Applicable Law, the Collateral shall remain personal
property irrespective of the manner of its attachment or affixation to realty.

               6. Covenants Regarding Collateral. Any and all injury to, or loss
or destruction of, the Collateral shall be at each Subsidiary's risk, and shall
not release any Subsidiary from its obligations hereunder. Each Subsidiary
agrees not to sell, transfer, assign, dispose of, mortgage, grant a security
interest in, or encumber any of the Collateral except as permitted under the
Loan Agreement. Each Subsidiary agrees to maintain in force such insurance with
respect to the Collateral as is required under the Loan Agreement. Each
Subsidiary agrees to pay all


                                       -7-
<PAGE>   165
required taxes, liens, and assessments upon the Collateral, its use or
operation, as required under the Loan Agreement. Each Subsidiary further agrees
that the Administrative Agent may, but shall in no event be obligated to,
following written notice to such Subsidiary, insure any of the Collateral in
such form and amount as the Administrative Agent may deem necessary or desirable
if any Subsidiary fails to obtain and maintain in effect insurance as required
by the Loan Agreement, and that the Administrative Agent may pay or discharge
any taxes or Liens (which are not Permitted Liens) on any of the Collateral, and
each Subsidiary agrees to pay any such sum so expended by the Administrative
Agent, with interest at the Default Rate, and such amounts shall be deemed to be
a part of the Obligations secured by the Collateral under the terms of this
Agreement.

               7. Covenants Regarding Contracts, Other Contracts and Leases.
Each Subsidiary shall (a) fulfill, perform and observe each and every material
condition and covenant contained in any of the Contracts, the Other Contracts or
the Leases, (b) give prompt notice to the Administrative Agent of any claim
alleging loss or damage in excess of $250,000.00 resulting from a material
default under any Contract, Other Contract or Lease given to such Subsidiary or
by such Subsidiary, (c) at the sole cost and expense of such Subsidiary, enforce
the performance and observance of each and every material covenant and condition
of the Contracts, the Other Contracts and the Leases to which it is a party in a
manner consistent with industry practice, and (d) appear in and defend any
action growing out of or in any manner connected with any material Contract,
Other Contract or Lease to which it is a party. None of the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents, or the
Administrative Agent shall have or acquire any liability or obligation under the
Contracts, the Other Contracts or the Leases, by reason of this Agreement, nor
shall any of them have any obligation to perform or take any action in respect
thereof. The rights and interests granted to the Administrative Agent hereunder
include all of the Subsidiaries' rights and title (i) to modify the Contracts,
the Other Contracts and the Leases, (ii) to terminate the Contracts, the Other
Contracts and the Leases, and (iii) to waive or release the performance or
observance of any obligation or condition of the Contracts, the Other Contracts
and the Leases; provided, however, that the Subsidiaries shall have the right to
exercise these rights in a fashion consistent with this Agreement and the Loan
Agreement prior to any Event of Default and that these rights shall not be
exercised by the Administrative Agent prior to an Event of Default. To the
extent that the such Subsidiary' rights under any Contract, Lease or Other
Contract may not be assigned as collateral security to the Administrative Agent
without the consent of another Person which has not been obtained, this
Agreement shall not constitute an assignment or an agreement to


                                       -8-
<PAGE>   166
assign the same if an attempted assignment would constitute a breach thereof or
be unlawful, and such Subsidiary, at its expense, shall use its best efforts to
obtain any such required consents as promptly as possible. If any such consent
shall not be obtained or if any attempted assignment would be ineffective or
would impair the Administrative Agent's rights under the Contract, Leases or
Other Contracts in question so that the Administrative Agent would not in effect
acquire the benefit of all such rights intended to be provided hereunder, such
Subsidiary, to the maximum extent permitted by law, shall act after the date
hereof as the Administrative Agent's agent in order to obtain for it the
benefits thereunder and shall cooperate, to the maximum extent permitted by law,
with the Administrative Agent in any other reasonable arrangement designed to
provide such benefits to the Administrative Agent.


               8. Remedies. Upon the occurrence and during the continuation of
an Event of Default, the Banks, the Syndication Agent, the Documentation Agent,
the Managing Agents, and the Administrative Agent shall have such rights and
remedies as are set forth in the Loan Agreement, the other Loan Documents and
herein, all the rights, powers and privileges of a secured party under the
Uniform Commercial Code of the State of New York and any other applicable
jurisdiction, and all other rights and remedies available to the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents, and the
Administrative Agent, or any of them, at law or in equity. Each Subsidiary
covenants and agrees that any notification of intended disposition of any
Collateral, if such notice is required by law, shall be deemed reasonably and
properly given if given in the manner provided for in paragraph 19 hereof at
least ten (10) days prior to such disposition. Upon the occurrence and during
the continuation of an Event of Default, the Administrative Agent shall have the
right to the appointment of a receiver for the properties and assets of each
Subsidiary, and each Subsidiary hereby consents to such rights and to such
appointment and hereby waives any objection such Subsidiary may have thereto and
hereby waives the right to have a bond or other security posted by the
Administrative Agent or any other Person in connection therewith. Each
Subsidiary agrees, after the occurrence of an Event of Default, to take any
actions that the Administrative Agent may reasonably request in order to enable
the Administrative Agent to obtain and enjoy the full rights and benefits
granted to the Administrative Agent under this Agreement and the other Loan
Documents. Without limiting the generality of the foregoing, upon the occurrence
and during the continuation of an Event of Default, each Subsidiary shall, at
such Subsidiary's cost and expense, use its best efforts to assist in obtaining
all approvals of the FCC which are then required by law for or in connection
with any action or transaction contemplated by this


                                       -9-
<PAGE>   167
Agreement or Article 9 of the Uniform Commercial Code as in effect in any
applicable jurisdiction, and, at the Administrative Agent's request, promptly
prepare, sign and file with the FCC the assignor's or transferor's portion of
any application or applications for consent to the assignment of the Licenses or
transfer of control thereof necessary or appropriate under the FCC's rules for
approval of any sale or transfer of the Administrative Agent's remedies under
this Agreement. The Administrative Agent shall have the right, in connection
with the issuance of any order for relief in a bankruptcy proceeding, to
petition the bankruptcy court for the transfer of control or assignment of the
Licenses to a receiver, trustee, transferee, or similar official or to any
purchaser of the Collateral pursuant to any public or private sale, foreclosure
or other exercise of remedies available to the Administrative Agent, all as
permitted by Applicable Law. All amounts realized or collected through the
exercise of remedies hereunder shall be applied to the Obligations as provided
in the Loan Agreement.

               9. Notification of Account Debtors. Upon the occurrence and
during the continuation of an Event of Default, the Administrative Agent may
notify the account debtors that all payments with respect to Accounts,
Contracts, Leases, Other Contracts and Miscellaneous Items are to be paid
directly to the Administrative Agent and any amount thereafter paid to any
Subsidiary shall be received in trust by such Subsidiary for the benefit of the
Administrative Agent and segregated from other funds of such Subsidiary and paid
over to the Administrative Agent in the form received (together with any
necessary endorsements).

               10. Remedies of Administrative Agent. Upon the occurrence of an
Event of Default and during the continuation thereof, upon giving written notice
to the Borrower, the Administrative Agent or its designee may proceed to perform
any and all of the obligations of any Subsidiary contained in any of the
Contracts, Other Contracts or Leases and exercise any and all rights of any
Subsidiary therein contained as fully as such Subsidiary itself could. Each
Subsidiary hereby appoints the Administrative Agent its attorney-in-fact, with
power of substitution, to take such action, execute such documents, and perform
such work as the Administrative Agent may deem appropriate in exercise of the
rights and remedies granted the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents, and the Administrative Agent, or any of them, herein
or in any other Loan Document following written notice to such Subsidiary. The
powers herein granted shall include, but not be limited to, powers to: (a) sue
on the Contracts, the Other Contracts or the Leases; (b) seek all governmental
approvals (other than FCC approvals) required for the operation of the business
of any Subsidiary; (c) modify or terminate the Contracts, the Other Contracts
and the Leases; and


                                      -10-
<PAGE>   168
(d) waive or release the performance or observance of any obligation under any
of the Contracts, Other Contracts or Leases. The power of attorney granted
herein is coupled with an interest and shall be irrevocable.

               11. Additional Remedies. Upon the occurrence of an Event of
Default and during the continuation thereof, should any Subsidiary fail to
perform or observe any covenant or comply with any condition contained in any of
the Contracts, the Other Contracts or the Leases, then following written notice
to such Subsidiary, the Administrative Agent may, but without obligation to do
so and without releasing such Subsidiary from its obligation to do so, perform
such covenant or condition and, to the extent that the Administrative Agent
shall incur any costs or pay any expenses in connection therewith, including any
reasonable costs or expenses of litigation associated therewith, such costs,
expenses or payments shall be included in the Obligations secured hereby and
shall bear interest from the payment of such costs or expenses by the
Administrative Agent at the Default Rate. Neither the Administrative Agent nor
any Bank shall be obliged to perform or discharge any obligation of any
Subsidiary under any of the Contracts, the Other Contracts or the Leases, and,
except as may result from the gross negligence or willful misconduct of the
Person seeking indemnification, each Subsidiary agrees to indemnify and hold the
Administrative Agent and each Bank harmless against any and all liability, loss
or damage which any such Person may incur under any of the Contracts, the Other
Contracts or the Leases or under or by reason of this Agreement, and any and all
claims and demands whatsoever which may be asserted against any Subsidiary by
reason of an act of the Administrative Agent or any Bank under any of the terms
of this Agreement or under the Contracts, the Other Contracts or the Leases.

               12. Administrative Agent May Collect Accounts. Each Subsidiary
hereby further appoints the Administrative Agent as its attorney-in-fact, with
power of substitution, with authority, upon the occurrence and during the
continuation of an Event of Default, to collect all Accounts and Miscellaneous
Items, to endorse the name of such Subsidiary on any note, acceptance, check,
draft, money order or other evidence of debt or of payment which constitutes a
portion of the Collateral and which may come into the possession of the Banks,
the Syndication Agent, the Documentation Agent, the Managing Agents, and the
Administrative Agent, or any of them, and generally to do such other things and
acts in the name of such Subsidiary with respect to the Collateral as are
necessary or appropriate to protect or enforce the rights hereunder of the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents, and
the Administrative Agent. Each Subsidiary further authorizes the Administrative
Agent, effective upon the occurrence of an Event of Default and


                                      -11-
<PAGE>   169
during the continuation thereof, to compromise and settle or to sell, assign or
transfer or to ask, collect, receive or issue any and all claims possessed by
any Subsidiary which constitute a portion of the Collateral, all in the name of
such Subsidiary. After deducting all reasonable expenses and charges (including
the Administrative Agent's reasonable attorneys' fees) of retaking, keeping,
storing and selling the Collateral, the Administrative Agent may apply the
proceeds in payment of any of the Obligations in the order of application set
forth in the Loan Agreement. The power of attorney granted herein is coupled
with an interest and shall be irrevocable. Each Subsidiary agrees that if steps
are taken by the Administrative Agent to enforce its rights hereunder, or to
realize upon any of the Collateral, such Subsidiary shall pay to the
Administrative Agent the amount of the Administrative Agent's costs, including
reasonable attorneys' fees, and each Subsidiary's obligation to pay such amounts
shall be deemed to be a part of the Obligations secured hereunder. Upon the
occurrence and during the continuation of an Event of Default, each Subsidiary
shall mark conspicuously its Accounts and chattel paper with a legend indicating
such Collateral is subject to the security interests created hereby and at the
request of the Administrative Agent deliver to the Administrative Agent each
promissory note, chattel paper, instrument or security constituting Collateral,
duly endorsed or accompanied by executed instruments of transfer, in form and
substance satisfactory to the Administrative Agent and segregate all proceeds of
any Collateral from other assets of such Subsidiary.

               13. Indemnification. Each Subsidiary shall indemnify and hold
harmless the Administrative Agent, each Bank and any other Person acting
hereunder for all losses, costs, damages, fees and expenses whatsoever
associated with the exercise of the rights granted hereunder and powers of
attorney granted herein and shall release the Administrative Agent, each Bank
and any other Person acting hereunder from all liability whatsoever for the
exercise of the foregoing rights and powers of attorney and all actions taken
pursuant thereto, except, in either event, in the case of gross negligence or
willful misconduct by the Person seeking indemnification.

               14. Remedies Cumulative. Each Subsidiary agrees that the rights
of the Banks, the Syndication Agent, the Documentation Agent, the Managing
Agents, and the Administrative Agent, or any of them, under this Agreement, the
Loan Agreement, any other Loan Document, or any other contract or agreement now
or hereafter in existence among the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents, the Administrative Agent and any
Subsidiary and the other obligors thereunder, or any of them, shall be
cumulative, and that the Administrative Agent, the Documentation Agent, each
Managing Agent, the


                                      -12-
<PAGE>   170
Syndication Agent, and each Bank may from time to time exercise such rights and
such remedies as such Person or Persons may have thereunder and under the laws
of the United States or any state, as applicable, in the manner and at the time
that such Person or Persons in its or their sole discretion desire, subject to
the terms of such agreements. Each Subsidiary further expressly agrees that the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents, and
the Administrative Agent shall in no event be under any obligation to resort to
any Collateral secured hereby prior to exercising any other rights that the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents, and
the Administrative Agent, or any of them, may have against such Subsidiary or
its property, and none of the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents, or the Administrative Agent shall be obliged to
resort to any other collateral or security for the Obligations, other than the
Collateral, prior to any exercise of the Administrative Agent's rights against
such Subsidiary and its property hereunder.

               15. Obligations Commercial in Nature. Each Subsidiary hereby
acknowledges that the Obligations arose out of a commercial transaction, and
agrees that if an Event of Default shall occur and be continuing, the
Administrative Agent shall have the right to immediate possession without notice
or a hearing, and hereby voluntarily, knowingly and intelligently waives any and
all rights it may have to any notice and posting of a bond by the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents, and the
Administrative Agent, or any of them, prior to seizure by the Administrative
Agent or any of its transferees, assigns or successors in interest of the
Collateral or any portion thereof.

               16. Amendments and Waivers. No amendment, modification, waiver,
transfer or renewal, extension, assignment or termination of this Agreement or
of the Loan Agreement or of any other Loan Document, or of any instrument or
document executed and delivered by any Subsidiary or any other obligor to the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents, and
the Administrative Agent, or any of them, nor additional advances made by the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents, and
the Administrative Agent, or any of them, to the Borrower, nor the taking of
further security, nor the retaking or re-delivery or release of the Collateral
to any Subsidiary by the Banks, the Syndication Agent, the Documentation Agent,
the Managing Agents, and the Administrative Agent, or any of them, nor any lack
of validity or enforceability of any Loan Document or any term thereof, nor any
other act of the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents, and the Administrative Agent, or any of them, shall release any
Subsidiary from any Obligation, except


                                      -13-
<PAGE>   171
a release or discharge executed in writing by the Administrative Agent in
accordance with the Loan Agreement with respect to such Obligation or upon full
payment and satisfaction of all Obligations and termination of the Commitments.
None of the Administrative Agent, the Documentation Agent, either Managing
Agent, the Syndication Agent, or any Bank shall by any act, delay, omission or
otherwise, be deemed to have waived any of its or their rights or remedies
hereunder, unless such waiver is in writing and signed by the Administrative
Agent in accordance with the Loan Agreement and then only to the extent therein
set forth. A waiver by the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents, and the Administrative Agent, or any of them, of any
right or remedy on any occasion shall not be construed as a bar to the exercise
of any such right or remedy which any such Person would otherwise have had on
any other occasion.

               17. Assignment. Each Subsidiary agrees that this Agreement or the
rights hereunder may in the discretion of the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents, and the Administrative Agent, or any
of them, as applicable, be assigned in whole or in part in connection with any
assignment of the Loan Agreement or the Indebtedness evidenced thereby, as
permitted thereunder. In the event this Agreement or the rights hereunder are so
assigned by any of the Banks, the Syndication Agent, the Documentation Agent,
the Managing Agents, and the Administrative Agent, the terms "Banks,"
"Syndication Agent," "Documentation Agent," "Managing Agents" and
"Administrative Agent" wherever used herein shall be deemed, as applicable, to
refer to and include any such assignee.

               18. Successors and Assigns. This Agreement shall apply to and
bind the respective successors and permitted assigns of each Subsidiary and
inure to the benefit of the successors and permitted assigns of the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents, and the
Administrative Agent.

               19. Notices. All notices and other communications required or
permitted hereunder shall be in writing and shall be given in a fashion
prescribed in Section 11.1 of the Loan Agreement with respect to the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents, and the
Administrative Agent, and in the fashion prescribed in Section 11.1 of the Loan

documents referred to herein, constitutes the entire agreement among the
Subsidiaries, the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents, and the Administrative Agent with respect to the matters
addressed herein and may not be modified except by a writing executed by the
Administrative Agent and delivered to the Subsidiaries.

               21. Severability. If any paragraph or part thereof of this
Agreement shall for any reason be held or adjudged to be invalid, illegal or
unenforceable by any court of competent jurisdiction, such paragraph or part
thereof so adjudicated invalid, illegal or unenforceable shall be deemed
separate, distinct and independent, and the remainder of this Agreement shall
remain in full force and effect and shall not be affected by such holding or
adjudication.

               22. FCC Consent. Notwithstanding anything herein which may be
construed to the contrary, no action shall be taken by the Administrative Agent

FCC or any governmental or other authority, have been satisfied. Each Subsidiary
covenants that upon request of the Administrative Agent it will cause to be
filed such applications and take such other action as may be requested by the

governmental or other authority which has granted any License to such Subsidiary

counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

               24. Changes in Applicable Law. The parties acknowledge their
intent that, upon the occurrence of an Event of Default and during the
continuance thereof, the Administrative Agent shall receive, to the fullest
extent permitted by Applicable Law and governmental policy (including, without
limitation, the rules, regulations and policies of the FCC), all rights
necessary or desirable to obtain, use or sell the Collateral and to exercise all
remedies available to it under this Agreement, the Uniform Commercial Code as in
effect in any applicable jurisdiction, or other Applicable Law. The parties
further acknowledge and agree


                                      -15-
<PAGE>   173
that, in the event of changes in law or governmental policy occurring subsequent
to the date hereof that affect in any manner the Administrative Agent's rights
of access to, or use or sale of, the Collateral, or the procedures necessary to
enable the Administrative Agent to obtain such rights of access, use or sale,
the Administrative Agent and each Subsidiary shall amend this Agreement in such
manner as the Administrative Agent shall reasonably request in order to provide
the Administrative Agent such rights to the greatest extent possible consistent
with Applicable Law and governmental policy.

               25. Administrative Agent. Each reference herein to any right
granted to, benefit conferred upon or power exercisable by the "Administrative
Agent" shall be a reference to the Administrative Agent for the benefit of all
the Banks, the Syndication Agent, the Documentation Agent and the Managing
Agents, and each action taken or right exercised hereunder shall be deemed to

and on behalf of both Managing Agents, the Documentation Agent and all the
Banks.

the Banks, the Syndication Agent, the Documentation Agent, the Managing Agents,

or agent thereof, unless contained herein forms any part of this Guaranty or has
induced the making hereof or shall be deemed in any way to affect such

Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, may, from time to time, without exonerating or releasing any Guarantor in

securities for the Obligations or any part thereof as the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent, or any of them, may deem proper, consistent with the Loan Agreement, or
(ii) release, discharge, abandon or otherwise deal with or fail to deal with any

perfecting or taking advantage of any security for the Obligations and accept or
make any compositions or arrangements, and realize upon any security for the

Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, may deem expedient, consistent with the Loan Agreement, all without notice
to such Guarantor.

<PAGE>   178
               5. Guaranty Unconditional. Each Guarantor acknowledges and agrees
that no change in the nature or terms of the Obligations or any of the
Guaranteed Agreements, or other agreements, instruments or contracts evidencing,
related to or attendant with the Obligations (including any novation), nor any
determination of lack of enforceability thereof, shall discharge all or any part
of the liabilities and obligations of such Guarantor pursuant to this Guaranty;
it being the purpose and intent of such Guarantor, the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative Agent
that the covenants, agreements and all liabilities and obligations of such
Guarantor hereunder are absolute, unconditional and irrevocable under any and
all circumstances. Without limiting the generality of the foregoing, such
Guarantor agrees that until each and every one of the covenants and agreements
of this Guaranty is fully performed, such Guarantor's undertakings hereunder
shall not be released, in whole or in part, by any action or thing which might,
but for this paragraph of this Guaranty, be deemed a legal or equitable
discharge of a surety or guarantor, or by reason of any waiver, omission of the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, or any of them, or their failure to proceed promptly
or otherwise, or by reason of any action taken or omitted by the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, whether or not such action or failure to
act varies or increases the risk of, or affects the rights or remedies of, such
Guarantor or by reason of any further dealings between the Borrower, the Banks,
the Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, or any other guarantor or surety, and such
Guarantor hereby expressly waives and surrenders any defense to its liability
hereunder, or any right of counterclaim or offset of any nature or description
which it may have or which may exist based upon, and shall be deemed to have
consented to, any of the foregoing acts, omissions, things, agreements or
waivers.

               6. Set-off. The Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents and the Administrative Agent, or any of them, may,
without demand or notice of any kind upon or to any Guarantor, at any time or
from time to time when any amount shall be due and payable hereunder by any
Guarantor, if the Borrower shall not have timely paid its Obligations, set off
and appropriate any property, balances, credit accounts or moneys of any
Guarantor in the possession of the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, or under the control of any of them for any purpose, which property,
balances, credit accounts or moneys shall thereupon be turned over and remitted
to the Administrative Agent, to be held and applied to

                                       -4-
<PAGE>   179
the Obligations by the Administrative Agent in accordance with the Loan
Agreement, and each Guarantor hereby grants to the Banks, the Syndication Agent,
the Documentation Agent, the Managing Agents and the Administrative Agent, a
security interest in all such property. The Administrative Agent shall give
written notice to the Borrower of the exercise of any of the foregoing rights
within one (1) Business Day following the exercise thereof.

               7. Maximum Guaranteed Amount. The creation or existence from time
to time of Obligations in excess of the amount committed to or outstanding on
the date of this Guaranty is hereby authorized by each Guarantor, without notice
to such Guarantor, and shall in no way impair or affect this Guaranty or the
rights of the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents and the Administrative Agent, or any of them, herein. It is the
intention of each Guarantor, the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents and the Administrative Agent, that such Guarantor's
obligations hereunder shall be in, but not in excess of, the Maximum Guaranteed
Amount. The "Maximum Guaranteed Amount" shall mean the greater of (a) the amount
of economic benefit received (directly or indirectly) by such Guarantor pursuant
to the Loan Agreement and the other Loan Documents, and (b) the maximum amount
which could be paid out by such Guarantor without rendering this Guaranty void
or voidable under Applicable Law including, without limitation, (i) Title 11 of
the United States Code, as amended, and (ii) applicable state law regarding
fraudulent conveyances.

               8. Bankruptcy. Upon the bankruptcy or winding up or other
distribution of assets of the Borrower or any Subsidiary of the Borrower (other
than such Guarantor) or of any surety or guarantor for the Obligations, the
rights of the Banks, the Syndication Agent, the Documentation Agent, the
Managing Agents and the Administrative Agent, or any of them, against a
Guarantor shall not be affected or impaired by the omission of the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, to prove its or their claim, as
appropriate, or to prove its or their full claim, as appropriate, and the Banks,
the Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent may prove such claims as they see fit and may refrain from
proving any claim and in their respective discretion they may value as they see
fit or refrain from valuing any security held by the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent, or any of them, without in any way releasing, reducing or otherwise
affecting the liability to the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents and the Administrative Agent of such Guarantor.

                                       -5-
<PAGE>   180
               9. Application of Payments. Any amount received by the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, from whatsoever source and applied toward
the payment of the Obligations shall be applied in such order of application as
is set forth in the Loan Agreement.

               10. Waivers by Guarantors. Each Guarantor hereby expressly
waives: (a) notice of acceptance of this Guaranty, (b) notice of the existence
or creation of all or any of the Obligations, (c) presentment, demand, notice of
dishonor, protest, and all other notices whatsoever, (d) all diligence in
collection or protection of or realization upon the Obligations or any part
thereof, any obligation hereunder, or any security for any of the foregoing and
(e) all rights of subrogation, indemnification, contribution and reimbursement
against the Borrower, all rights to enforce any remedy the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, may have against the Borrower and any
benefit of, or right to participate in, any collateral or security now or
hereinafter held by the Banks, the Syndication Agent, the Documentation Agent,
the Managing Agents and the Administrative Agent, or any of them, in respect of
the Obligations, even upon payment in full of the Obligations. Any payments
received by the Guarantor in violation of this Section shall be held in trust by
the Guarantor for the benefit of the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent and shall
be promptly delivered to the Administrative Agent. If a claim is ever made upon
the Banks, the Syndication Agent, the Documentation Agent, the Managing Agents
and the Administrative Agent, or any of them, for the repayment or recovery of
any amount or amounts received by any of them in payment of any of the
Obligations and such Person repays all or part of such amount by reason of (a)
any judgment, decree, or order of any court or administrative body having
jurisdiction over such Person or any of its property, or (b) any good faith
settlement or compromise of any such claim effected by such Person with any such
claimant, including the Borrower, then in such event each Guarantor agrees that
any such judgment, decree, order, settlement, or compromise shall be binding
upon such Guarantor, notwithstanding any revocation hereof or the cancellation
of any promissory note or other instrument evidencing any of the Obligations,
and such Guarantor shall be and remain obligated to such Person hereunder for
the amount so repaid or recovered to the same extent as if such amount had never
originally been received by such Person.

               11. Assignment by Banks, Syndication Agent, Managing Agents,
Administrative Agent. To the extent permitted under the Loan Agreement, the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative

                                       -6-
<PAGE>   181
Agent may each, and without notice of any kind, sell, assign or transfer all or
any of the Obligations, and in such event each and every immediate and
successive assignee, transferee, or holder of all or any of the Obligations,
shall have the right to enforce this Guaranty, by suit or otherwise, for the
benefit of such assignee, transferee or holder as fully as if such assignee,
transferee or holder were herein by name specifically given such rights, powers
and benefits.

               12. Remedies Cumulative. No delay by the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent, or any of them, in the exercise of any right or remedy shall operate as a
waiver thereof, and no single or partial exercise by the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent, or any of them, of any right or remedy shall preclude other or further
exercise thereof or the exercise of any other right or remedy. No action by the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, or any of them, permitted hereunder shall in any way
impair or affect this Guaranty. For the purpose of this Guaranty, the
Obligations shall include, without limitation, all Obligations of the Borrower
to the Banks, the Syndication Agent, the Documentation Agent, the Managing
Agents and the Administrative Agent notwithstanding any right or power of any
third party, individually or in the name of the Borrower or any other Person, to
assert any claim or defense as to the invalidity or unenforceability of any such
Obligation, and no such claim or defense shall impair or affect the obligations
of any Guarantor hereunder.

               13. Successors and Assigns. This Guaranty shall be binding upon
each Guarantor, its successors and assigns and inure to the benefit of the
successors and assigns of the Banks, the Syndication Agent, the Documentation
Agent, the Managing Agents and the Administrative Agent. No Guarantor shall
assign its rights or obligations under this Guaranty without the consent of all
the Banks, nor shall such Guarantor amend this Guaranty, without the consent of
the Majority Banks.

               14. Miscellaneous. This is a Guaranty of payment and not of
collection. In the event of a demand upon any Guarantor under this Guaranty,
such Guarantor shall be held and bound to the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent directly
as debtor in respect of the payment of the amounts hereby guaranteed. All
reasonable costs and expenses, including attorneys' fees and expenses, incurred
by the Banks, the Syndication Agent, the Documentation Agent, the Managing
Agents and the Administrative Agent, or any of them, in obtaining performance of
or collecting payments due under this Guaranty shall be deemed part of the

                                       -7-
<PAGE>   182
Obligations guaranteed hereby. Any notice or demand which the Banks, the
Syndication Agent, the Documentation Agent, the Managing Agents and the
Administrative Agent, or any of them, may wish to give shall be served upon a
Guarantor in the fashion prescribed for notices in Section 11.1 of the Loan
Agreement in care of the Borrower at the address for the Borrower set forth in
or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and the
notice so sent shall be deemed to be served as set forth in Section 11.1 of the
Loan Agreement.

               15. Loans Benefit Guarantor. Each Guarantor expressly represents
and acknowledges that any financial accommodations by the Banks, the Syndication
Agent, the Documentation Agent, the Managing Agents and the Administrative
Agent, or any of them, to the Borrower, including, without limitation the
extension of the Loans, are and will be of direct interest, benefit and
advantage to such Guarantor.

               16. Solvency. Each Guarantor expressly represents and warrants
that as of the date hereof and after giving effect to the transactions
contemplated by the Loan Documents (i) the property of such Guarantor, at a fair
valuation, will exceed its debt; (ii) the capital of such Guarantor will not be
unreasonably small to conduct its business; (iii) such Guarantor will not have
incurred debts, or have intended to incur debts, beyond its ability to pay such
debts as they mature; and (iv) the present fair salable value of the assets of
such Guarantor will be materially greater than the amount that will be required
to pay its probable liabilities (including debts) as they become absolute and
matured. For purposes of this Section 16, "debt" means any liability on a claim,
and "claim" means (a) the right to payment, whether or not such right is reduced
to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured,
undisputed, legal, equitable, secured or unsecured, or (b) the right to an
equitable remedy for breach of performance if such breach gives rise to a right
to payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, undisputed, secured or
unsecured.

               17. Visits and Inspections. Each Guarantor covenants and agrees
that so long as any amount is owing on account of Obligations or otherwise
pursuant to this Guaranty, such Guarantor shall permit representatives of the
Banks, the Syndication Agent, the Documentation Agent, the Managing Agents and
the Administrative Agent, or any of them, to visit and inspect properties of
such Guarantor during normal business hours after reasonable notice, inspect
such Guarantor's books and records and discuss with the principal officers of
such Guarantor its businesses, assets, liabilities, financial positions, results
of operations and business prospects.

                       FORM OF SUBSIDIARY PLEDGE AGREEMENT

         THIS SUBSIDIARY PLEDGE AGREEMENT (the "Agreement"), entered into as of
this ____ day of September, 1996 by and between ____________________, a
______________ corporation, (the "Pledgor") and Toronto Dominion (Texas), Inc.,
as administrative agent (the "Administrative Agent") for itself and on behalf of
the Managing Agents, the Documentation Agent, the Syndication Agent (each as
described below) and the Banks (defined in the Loan Agreement defined below),

                              W I T N E S S E T H:

         WHEREAS, Metrocall, Inc., a corporation organized under the laws of the
State of Delaware (the "Borrower"), the Banks, The First National Bank of
Boston, as syndication agent (in such capacity, the "Syndication Agent"), The
Toronto-Dominion Bank, as documentation agent (in such capacity, the
"Documentation Agent"), The Toronto-Dominion Bank and The First National Bank of
Boston, as managing agents for the Banks (collectively, in such capacity, the
"Managing Agents"), and the Administrative Agent are all parties to that certain
Amended and Restated Loan Agreement dated as of September 20, 1996 (as amended,
restated or otherwise modified or replaced from time to time, the "Loan
Agreement"); and

         WHEREAS, as a requirement under the Loan Agreement, the Pledgor is 
required to execute and deliver this Agreement; and

         WHEREAS, the Administrative Agent has agreed to act as administrative
agent for itself and on behalf of the Managing Agents, the Documentation Agent,
the Syndication Agent and the Banks in connection with the transactions
contemplated by the Loan Agreement; and

         WHEREAS, the Pledgor is a Subsidiary of the Borrower and is engaged in
the business of owning, constructing, managing, operating and investing in
paging service systems and communications businesses incidental or directly
relating thereto as an integrated operation with the Borrower and its other
Subsidiaries (as defined in the Loan Agreement); and

         WHEREAS, the Pledgor has determined that its execution, delivery and
performance of this Agreement directly benefit, and are within the corporate
purposes and in the best interests of the Pledgor; and
<PAGE>   186

         WHEREAS, to secure the payment and performance of, among other things,
the obligations of the Pledgor arising under that certain Amended and Restated
Master Subsidiary Guaranty of even date herewith, the Pledgor and the
Administrative Agent (on behalf of itself, the Managing Agents, the
Documentation Agent, the Syndication Agent and the Banks) have agreed that the
shares of capital stock (the "Stock") owned by the Pledgor in each of the
Subsidiaries of the Pledgor listed on Schedule 1 attached hereto (the
"Subsidiaries") shall be pledged by the Pledgor to the Administrative Agent (on
behalf of itself, the Managing Agents, the Documentation Agent, the Syndication
Agent and the Banks) to secure the Obligations (as defined below);

         NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree that capitalized terms used herein shall
have the meanings ascribed to them in the Loan Agreement to the extent not
otherwise defined or limited herein, and further agree as follows:

         1.   Warranty. The Pledgor hereby represents and warrants to the
Administrative Agent, the Managing Agents, the Documentation Agent, the
Syndication Agent and the Banks that, except for the security interest created
hereby, the Pledgor owns the Stock, which constitutes the percentage of the
issued and outstanding stock of each Subsidiary as set forth on Schedule 1
attached hereto, free and clear of all Liens, that the Stock is duly issued,
fully paid and non-assessable, and that the Pledgor has the unencumbered right
to pledge the Stock. In addition, Pledgor represents and covenants as follows:
(1) the Stock represents all of Pledgor's shares of capital stock in each
Subsidiary; (2) upon possession of the Stock by the Administrative Agent, the
Administrative Agent shall have a valid and perfected first priority security
interest in the Stock, securing the payment of the Obligations; and (3) except
as noted on Schedule 2 attached hereto, the Stock represents all the outstanding
shares of stock issued by any Subsidiary of the Pledgor.

         2.   Security Interest. The Pledgor hereby unconditionally grants and
assigns to the Administrative Agent, for itself and on behalf of the Managing
Agents, the Documentation Agent, the Syndication Agent and the Banks and their
respective successors and assigns, a continuing security interest in and
security title to the Stock and any other shares of capital stock of any
Subsidiary of the Pledgor obtained in the future, and in each case, all
certificates representing such shares, all rights, options, warrants, stock or
other securities or other property which may hereafter be received, receivable
or distributed in respect of the Stock, together with all proceeds of the
foregoing, including, without limitation, all dividends, cash, notes, securities
or other property from time to time acquired, 


                                       -2-
<PAGE>   187
receivable or otherwise distributed in respect of, or in exchange for, the
foregoing, all of which shall constitute "Stock" hereunder. The Pledgor herewith
delivers to and deposits with the Administrative Agent all of its right, title
and interest in and to the Stock, together with certificates representing the
Stock, and undated stock powers endorsed in blank, as security for the payment
and performance of all of the obligations of the Pledgor and any other obligor
to the Administrative Agent, the Managing Agents, the Documentation Agent, the
Syndication Agent or the Banks, or any of them, under this Agreement and the
Subsidiary Guaranty and any extensions, renewals or amendments of any of the
foregoing, however created, acquired, arising or evidenced, whether direct or
indirect, absolute or contingent, now or hereafter existing, or due or to become
due (the "Obligations"); it being the intention of the parties hereto that
beneficial ownership of the Stock, including, without limitation, all voting,
consensual and dividend rights, shall remain in the Pledgor until the occurrence
of an Event of Default and until the Administrative Agent shall notify the
Pledgor of the Administrative Agent's exercise of voting and dividend rights to
the Stock pursuant to Section 9 of this Agreement.

         3.       Additional Shares.  In the event that, during the term
of this Agreement:

                  (a)    any stock dividend, stock split, reclassification,
         readjustment, or other change is declared or made in the capital
         structure of any Subsidiary, or any new stock is issued by such
         Subsidiary, then, in any event, all new, substituted, and additional
         shares, or other securities, which are issued to the Pledgor in
         connection therewith shall be promptly delivered to the Administrative
         Agent, together with undated stock powers endorsed in blank by the
         Pledgor, and shall thereupon constitute Stock to be held by the
         Administrative Agent under the terms of this Agreement; and

                  (b)    any subscriptions, warrants or any other rights or 
         options shall be issued in connection with the Stock, all new stock or
         other securities acquired through such subscriptions, warrants, rights 
         or options by the Pledgor shall be promptly delivered to the
         Administrative Agent, together with undated Stock powers endorsed in
         blank, and shall thereupon constitute Stock to be held by the
         Administrative Agent under the terms of this Agreement.

         4.       Default. In the event of the occurrence of an Event of Default
and so long as any such Event of Default is continuing, and subject to Section
13 hereof, the Administrative Agent may sell or otherwise dispose of the Stock
at a public or private sale or make other commercially reasonable disposition of
the Stock or any portion thereof after fifteen (15) days' notice to the Pledgor;
and the Administrative Agent, the Managing Agents, 


                                       -3-

<PAGE>   188

the Documentation Agent, the Syndication Agent and the Banks, or any of them,
may purchase the Stock or any portion thereof at any public sale. The proceeds
of the public or private sale or other disposition shall be applied first to the
costs of the Administrative Agent incurred in connection with the sale,
expressly including, without limitation, any costs under Section 7 hereof, and
then as provided in the Loan Agreement. In the event the proceeds of the sale or
other disposition of the Stock are insufficient to satisfy the Obligations, the
Pledgor shall remain liable for any such deficiency. Pledgor waives the rights
of equity of redemption, appraisal, notice of acceptance, presentment, demand
and marshalling to the extent applicable.

         5.    Additional Rights of Secured Party. In addition to its rights and
privileges under this Agreement, the Administrative Agent, on behalf of itself,
the Managing Agents, the Documentation Agent, the Syndication Agent and the
Banks, shall have all the rights, powers and privileges of a secured party under
the Uniform Commercial Code as in effect in any applicable jurisdiction and
other Applicable Law.

         6.    Return of Stock to the Pledgor. Upon payment in full of all
principal and interest on the Notes, full performance by the Borrower of all
covenants, undertakings and obligations under the Loan Agreement and the other
Loan Documents, and satisfaction in full of any other Obligations, other than
the Obligations which survive the termination of the Loan Agreement as provided
in Section 11.16 of the Loan Agreement, and after such time as the Banks shall
have no obligation to make any further Advances to the Borrower, this Agreement
shall terminate and the Administrative Agent shall return the remaining Stock
and all rights received by the Administrative Agent as a result of its
possessory interest in the Stock to the Pledgor.

         7.    Disposition of Stock by Administrative Agent. The Stock is not
registered or qualified under the various Federal or state securities laws of
the United States and disposition thereof after an Event of Default may be
restricted to one or more private (instead of public) sales in view of the lack
of such registration. The Pledgor understands that upon such disposition, the
Administrative Agent may approach only a restricted number of potential
purchasers and further understands that a sale under such circumstances may
yield a lower price for the Stock than if the Stock were registered and
qualified pursuant to Federal and state securities laws and sold on the open
market. The Pledgor, therefore, agrees that:

               (a)   if the Administrative Agent shall, pursuant to the terms
         of this Agreement, sell or cause the Stock or any portion thereof to be
         sold at a private sale, the Administrative Agent shall have the right
         to rely upon the advice and opinion of any national brokerage or
         investment firm having recognized expertise and experience in

 
                                       -4-
<PAGE>   189
         connection with shares of companies providing paging and related 
         wireless communication services (but shall not be obligated to seek 
         such advice, and the failure to do so shall not be considered in
         determining the commercial reasonableness of such action) as to the
         best manner in which to expose the Stock for sale and as to the best
         price reasonably obtainable at the private sale thereof; and

                (b)   that such reliance shall be conclusive evidence that the
         Administrative Agent has handled such disposition in a commercially
         reasonable manner.

         8.     Pledgor's Obligations Absolute. The obligations of the Pledgor
under this Agreement shall be direct and immediate and not conditional or
contingent upon the pursuit of any remedies against the Borrower or any other
Person, nor against other security or liens available to the Administrative
Agent, either Managing Agent, the Documentation Agent, the Syndication Agent or
any Bank. The Pledgor hereby waives any right to require that an action be
brought against any other Person or to require that resort be had to any
security or to any balance of any deposit account or credit on the books of the
Administrative Agent, either Managing Agent, the Documentation Agent, the
Syndication Agent or any of the Banks in favor of any other Person prior to the
exercise of remedies hereunder, or to require action hereunder prior to resort
by the Administrative Agent to any other security or collateral for the
Obligations. No amendment, modification, waiver, transfer or renewal, extension,
assignment or termination of this Agreement or of the Loan Agreement or of any
other Loan Document, or of any instrument or document executed and delivered by
the Pledgor or any other obligor to the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, nor additional advances made by the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, to the Borrower, nor the taking of further security, nor the retaking or
re-delivery or release of the Collateral to the Borrower or any other person or
any other collateral or guaranty by the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, nor any lack of validity or enforceability of any Loan Document or any
term thereof, nor any other act of the Banks, the Syndication Agent, the
Documentation Agent, the Managing Agents and the Administrative Agent, or any of
them, shall release the Pledgor from any Obligation, except a release or
discharge executed in writing by the Administrative Agent in accordance with the
Loan Agreement with respect to such Obligation or upon full payment and
satisfaction of all Obligations. Neither the Administrative Agent, nor either
Managing Agent, nor the Documentation Agent, nor the Syndication Agent, nor any
Bank shall, by any act, delay, omission or otherwise, be deemed to have waived
any of its or their rights or remedies hereunder, unless such waiver is in
writing and signed 


                                       -5-
<PAGE>   190
by the Administrative Agent in accordance with the Loan Agreement and then only
to the extent therein set forth. A waiver by the Banks, the Syndication Agent,
the Documentation Agent, the Managing Agents and the Administrative Agent, or
any of them, of any right or remedy on any occasion shall not be construed as a
bar to the exercise of any such right or remedy which any such Person would
otherwise have had on any other occasion.

         9.     Voting Rights.

                (a)   For so long as any Obligations remain unpaid, after and
         during the continuation of an Event of Default, but subject to the
         provisions of Section 13 hereof, (i) the Administrative Agent may, upon
         fifteen (15) days' prior written notice to the Pledgor of its intention
         to do so, exercise all voting rights, and all other ownership or
         consensual rights of the Stock, but under no circumstances is the
         Administrative Agent obligated by the terms of this Agreement to
         exercise such rights, and (ii) the Pledgor hereby appoints the
         Administrative Agent, which appointment shall be effective on the
         fifteenth (15th) day following the giving of notice by the
         Administrative Agent as provided in the foregoing Section 9(a)(i), the
         Pledgor's true and lawful attorney-in-fact and IRREVOCABLE PROXY to
         vote the Stock in any manner the Administrative Agent deems advisable
         for or against all matters submitted or which may be submitted to a
         vote of shareholders. The power-of-attorney granted hereby is coupled
         with an interest and shall be irrevocable.

                (b)   For so long as the Pledgor shall have the right to vote
         the Stock, the Pledgor covenants and agrees that it will not, without
         the prior written consent of the Administrative Agent, vote or take any
         consensual action with respect to the Stock which would constitute an
         Event of Default.

         10.    Notices. All notices and other communications required or 
permitted hereunder shall be in writing, and shall be given in the fashion set
forth in Section 11.1 of the Loan Agreement, and with respect to the Pledgor, at
the address for the Borrower set forth in or otherwise provided pursuant to
Section 11.1 of the Loan Agreement.

         11.    Binding Agreement. The provisions of this Agreement shall be
construed and interpreted, and all rights and obligations of the parties hereto
determined, in accordance with the internal laws of the State of New York
applicable to contracts made and to be performed in the State of New York. This
Agreement, together with all documents referred to herein, constitutes the
entire agreement between the parties with respect to the matters addressed
herein and may not be modified except by a writing executed by the
Administrative Agent and the Pledgor and delivered by the Administrative Agent
to the Pledgor.


                                       -6-
<PAGE>   191
         12.   Severability. If any paragraph or part thereof shall for any 
reason be held or adjudged to be invalid, illegal or unenforceable by any court
of competent jurisdiction, such paragraph or part thereof so adjudicated
invalid, illegal or unenforceable shall be deemed separate, distinct and
independent, and the remainder of this Agreement shall remain in full force and
effect and shall not be affected by such holding or adjudication.

         13.   FCC Compliance. Notwithstanding anything herein which may be
construed to the contrary, no action shall be taken by the Administrative Agent
which may require the consent or approval of the FCC or other governmental
authority, and the proxy granted in Section 9(a) hereof shall not become
effective, unless and until all requirements of the Communications Act or other
Applicable Law, requiring the consent to or approval of such action by the FCC
or other governmental authority have been satisfied. The Pledgor covenants that,
following and during the continuance of an Event of Default, upon request of the
Administrative Agent, it will cause to be filed such applications and take such
other action as may be requested by the Administrative Agent to obtain consent
or approval of the FCC or other governmental authority to any action
contemplated by this Agreement and to give effect to the security interest of
the Administrative Agent, including, without limitation, the execution of an
application for consent by the FCC or other governmental authority to an
assignment or transfer involving a change in ownership or control pursuant to
the provisions of the Communications Act or other Applicable Law.

         14.   Care and Custody of Collateral. The Administrative Agent shall be
deemed to have exercised reasonable care in the custody and preservation of the
Collateral if it takes such action for that purpose as is customary in the
banking industry or as the Pledgor shall request in writing, but failure of the
Administrative Agent to comply with any such request shall not of itself be
deemed a failure to exercise reasonable care, and no failure of the
Administrative Agent to preserve or protect any rights with respect to the
Collateral against prior parties, or to do any act not customary in the banking
industry with respect to preservation of the Collateral not so requested by the
Pledgor, shall be deemed a failure to exercise reasonable care in the custody or
preservation of the Collateral.

         15.   Counterparts.  This Agreement may be executed in multiple 
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

         16.   Administrative Agent.  Each reference herein to any right granted
to, benefit conferred upon or power exercisable by the "Administrative Agent"
shall be a reference to the Administrative Agent for the benefit of the Managing
Agents, the Documentation Agent, the Syndication Agent and the Banks, and


                                       -7-
<PAGE>   192
each action taken or right exercised hereunder shall be deemed to have been so
taken or exercised by the Administrative Agent for the benefit of and on behalf
of the Managing Agents, the Documentation Agent, the Syndication Agent and all
of the Banks.

         A.   Metrocall, Inc., a Delaware corporation (the "Borrower"), the

certain Amended and Restated Loan Agreement dated as of September 20, 1996 (the

The Assignor's pro rata portions of the Commitments are the amounts specified in
Item 1 of Schedule 1 hereto (the "Assignor's Commitments"). The aggregate
principal amounts of outstanding Loans made by the Assignor to the Borrower
under the Commitments pursuant to the Assignor's Commitments are specified in
Item 2 of Schedule 1 hereto (the "Assignor's Loans"). All capitalized terms not

         B.   The Assignor wishes to sell and assign to the Assignee, and the
Assignee wishes to purchase and assume from the Assignor, (i) the portion of the
Assignor's Commitments specified in Item 3 of Schedule 1 hereto which is
equivalent to the percentage of the Facility A Commitment and the Facility B
Commitment specified in Item 4 of Schedule 1 ("Assigned Commitments"), and (ii)

<PAGE>   195
         The parties agree as follows:

         1.  Assignment. Subject to the terms and conditions set forth herein,
the Assignor hereby sells and assigns to the Assignee, and the Assignee
purchases and assumes from the Assignor, without recourse to the Assignor, on
the date set forth above (the "Assignment Date") (a) all right, title, and
interest of the Assignor to the Assigned Loans and (b) all obligations of the
Assignor under the Loan Agreement with respect to the Assigned Commitments. As
full consideration for the sale of the Assigned Loans and the Assigned
Commitments, the Assignee shall pay to the Assignor on the Assignment Date such
amount as shall have been agreed to between the Assignor and the Assignee (the
"Purchase Price").

         2.  Consents and Undertaking. The Administrative Agent and the Borrower
hereby consent to the assignment made herein, and the Borrower hereby undertakes
within five (5) Business Days from the Assignment Date to provide new Facility A
Notes and Facility B Notes to the Administrative Agent, for the benefit of the
Assignee and the Assignor, as appropriate to reflect the portion of the Facility
A Commitment and the Facility B Commitment, as appropriate, held by each of the
Assignee and the Assignor after giving effect to the assignment contemplated by
this Agreement. The Assignor agrees on the Business Day following receipt by the
Administrative Agent of the new Notes, to return its superseded Note to the
Administrative Agent, which shall thereupon transmit the new Notes to the
Assignor and the Assignee and the superseded Notes to the Borrower for
cancellation.

         3.  Representations and Warranties. Each of the Assignor and the
Assignee represents and warrants to the other, to the Administrative Agent and

deliver this Agreement and to perform the provisions of this Agreement; (b) the
execution, delivery, and performance of this Agreement have been authorized by
all necessary action, corporate or otherwise, on its part and do not violate any
provisions of its charter or by-laws or any contractual obligations or
requirement of law binding on it; and (c) this Agreement constitutes its legal,
valid and binding obligation, enforceable against it in accordance with its
terms subject, as to enforcement of remedies, to the following qualifications:
(i) an order of specific performance and an injunction are discretionary
remedies and, in particular, may not be available where damages are considered
an adequate remedy at law, and (ii) enforcement may be limited by bankruptcy,
insolvency, liquidation, reorganization, reconstruction and other similar laws
affecting enforcement of creditors' rights generally (insofar as any such law
relates to the bankruptcy, insolvency or similar event of the Assignee or the
Assignor, as the case may be). The Assignee further represents and warrants to
the

Assignor, the Administrative Agent and the Borrower that its purchase of the
Assigned Loans and the Assigned Commitments does not constitute a "prohibited
transaction" as defined in Section 4.1(m) of the Loan Agreement.

Assignee hereunder shall be subject to the fulfillment of the condition that (a)
the Assignor shall have received payment in full of the Purchase Price and (b)

Administrative Agent for the benefit of the Assignee as provided in the Loan
Agreement; provided, however, that the Borrower and the Administrative Agent
shall be entitled to continue to deal solely and directly with the Assignor in
connection with the interests so assigned until (i) the Administrative Agent
shall have received a copy of this Assignment and Assumption Agreement duly
executed by the Assignor, the Assignee, and the Borrower, and shall have
received the assignment fee described in Section 11.5 of the Loan Agreement, and
(ii) the Assignor shall have delivered to the Administrative Agent any Notes
that shall be subject to the assignment. From and after the date (the "Effective
Date") on which the Administrative Agent shall notify the Borrower, the Assignee
and the Assignor that (i) and (ii) have occurred and all consents (if any)
required have been given, the Assignee shall be deemed to be a party to the Loan
Agreement and, to the extent that rights and obligations thereunder shall have
been assigned to Assignee as provided herein, shall have the rights and
obligations of a Bank under the Loan Agreement. After the Effective Date, and
with respect to all such amounts accrued from the Assignment Date, (a) all
interest, principal, fees, and other amounts that would otherwise be payable to
the Assignor in respect of the Assigned Loans and the Assigned Commitments shall
be paid to the Assignee, (b) if the Assignor receives any payment on account of
the Assigned Loans or the Assigned Commitments that is payable to the Assignee,
the Assignor shall promptly deliver such payment to the Assignee, and (c) if the

The Assignee agrees to deliver to the Borrower and the Administrative Agent on
or before the Effective Date such Internal Revenue Service forms as may be
required to establish that the Assignee is entitled to receive payments under
the Loan Agreement without deduction or withholding of tax.
