prices prevailing at the time of sale or at prices otherwise negotiated. See
"Selling Stockholder" and "Plan of Distribution."
    
 
     The Company will not receive any of the proceeds from the sale of the
Shares being sold by the Selling Stockholder. The Company has agreed to bear the
expenses incurred in connection with the registration of the Shares. The Selling
Stockholder will pay or assume brokerage commissions or similar charges incurred

                                  THE COMPANY
 
   
     Metrocall has 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 fifth
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 or refinance approximately $125 million of A+
Network indebtedness in connection with 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 November 7, 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. See "RECENT
DEVELOPMENTS -- Offer and Solicitation Relating to A+ Network Notes." 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
 
   
     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 has
received commitments to purchase $25 million of preferred stock to be issued by
Metrocall and is exploring options for issuing up to an additional $15 million
of preferred stock. There can be no assurance that it will be successful in
completing these transactions or any other transaction. 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 $5 3/8 per share to a high of $29 per
share. On November 7, 1996, the closing price of Metrocall Common Stock was
$5.375, which was less than the book value per share on September 30, 1996 of
approximately $8.24. 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 1,961,942 million shares registered
by the
    
 
                                        6

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 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 $6 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 in mid-November
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 November
4, 1996 was $7.25 per share, or a decrease, based upon market value, of
approximately $60 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 $10,888,778 (consisting of $9,500,000 purchase price, plus
$424,384 working capital adjustment, plus $971,894 capital expenditure
adjustment, less $7,500 for certain expenses) 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 the effective date
of the Registration Statement in the case of shares not held in escrow. Of the
$9,500,000 purchase price, shares of Common Stock with a value of $1,500,000
were placed in escrow at closing to cover the sellers' indemnity obligations.
The number of shares in escrow will be adjusted 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 the date of
release from 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 purchase 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 November 7, 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 November 7, 1996, the interest rate on Eurodollar
rate advances was 8.13% and no base 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.

OFFER AND SOLICITATION RELATING TO A+ NETWORK NOTES
    
 
   
     On October 9, 1996, Metrocall commenced a tender offer for all $125 million
principal amount of A+ Network's outstanding 11 7/8% Senior Subordinated Notes
due 2005 ("A+ Notes") and a solicitation of consents to amend the indenture
governing the A+ Notes to eliminate restrictive covenants and certain events of
default. Holders of the A+ Notes who validly consent and tender will receive
aggregate payments of $1,010, plus accrued and unpaid interest, for each $1,000
principal amount of bonds. Metrocall intends to finance the offer and
solicitation through advances under the New Credit Facility. The purchase or
refinancing of the A+ Notes is not a condition of the Merger. The successful
completion of the tender offer is expected to enable Metrocall to reduce its
interest expense obligations after the Merger and, if all the A+ Notes are
tendered and accepted, simplify its capital structure. The successful completion
of the solicitation will provide Metrocall financial flexibility by eliminating
potentially overlapping or more restrictive covenants than those in the
indenture governing Metrocall's senior subordinated debt. The tender offer and
consent are subject to various conditions, including, among others, (i) there
having been validly tendered and not withdrawn prior to the solicitation
expiration date a majority of the aggregate outstanding principal amount of the
A+ Notes, (ii) receipt by Metrocall of consents from a majority of the aggregate
outstanding principal amount of the A+ Notes prior to the solicitation
expiration date, (iii) the execution of a supplemental indenture incorporating
the proposed amendments, (iv) satisfaction of all conditions to the availability
of bank financing and the receipt by the Metrocall of sufficient funds
thereunder to make the payments pursuant to the tender offer and solicitation
including a requirement that Metrocall raise cash proceeds of at least $25
million in equity, and (v) consummation of the Merger. The solicitation expired
November 5, 1996, and consents were received from holders of approximately
$121.5 million principal amount of A+ Notes. The tender offer will expire
November 14, 1996, subject to extension by Metrocall. As of November 5, 1996, A+
Notes with a principal amount of approximately $121.5 million had been validly
tendered and not withdrawn.

     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.
 
                                       13
<PAGE>   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, 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).

(1) Includes 311,764 Shares which will be issued as an adjustment based on the
    market price of Common Stock for the five trading day period ending on
    November 6, 1996 and 232,997 shares which may be issued depending upon

    for the five trading day period prior to the second business day prior to
    the date of release from escrow of shares held in escrow.
    
   
(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 August 30,
    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
 
                                       15
<PAGE>   17
 
(as defined below) or (ii) the opening ask price immediately following the
delivery of notice of the exercise of 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,
Cutler & Pickering, Washington, D.C.

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>   20
 
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.

     (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an

<PAGE>   21
 
incorporated by reference in the registration statement 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.
 
     (b) The undersigned registrant hereby undertakes to supply by means of
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     (c) The undersigned registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
            a post-effective amendment to this registration statement:
 
                (i)  To include any prospectus required by section 10(a)(3) of
                     the Securities Act of 1933;
 
                (ii) To reflect in the prospectus any facts or events arising
                     after the effective date of the registration statement (or
                     the most recent post-effective amendment thereof) which,
                     individually or in the aggregate, represent a fundamental
                     change in the information set forth in the registration
                     statement. Notwithstanding the foregoing, any increase or
                     decrease in volume of securities offered (if the total
                     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.

        Re:     Metrocall, Inc. Registration Statement on Form S-3

Dear Ladies and Gentlemen:

        We have acted as counsel to Metrocall, Inc., a Delaware corporation
(the "Company"), in connection with a Registration Statement (the "Registration
Statement") on Form S-3 initially filed with the Securities and Exchange
Commission (the "Commission") on October 1, 1996 under the Securities Act of
1933, as amended.  The Registration Statement relates to the registration of
the shares of Common Stock of the Company, par value $0.01 per share (the
"Shares"), issued in connection with the purchase by the Company of the assets
of O.R. Estman, Inc. d/b/a Satellite Paging ("Satellite") and Dana Paging, Inc.
d/b/a Message Network ("Message Network").  The purchase was effected pursuant
to an Asset Purchase Agreement dated as of February 28, 1996, as amended
pursuant to an amendment dated August 30, 1996 (the "Purchase Agreement"),
among the Company, Satellite, Message Network, Bertram M. Wachtel, Edward R.
Davalos and Kevan D. Bloomgren.  For the purposes of this opinion, we have
examined and relied upon such documents, records, certificates and other
instruments as we have deemed necessary.

        Based solely upon the foregoing, and upon our examination of such
questions of law and statutes as we have considered necessary or appropriate,
and subject to the assumptions, qualifications, limitations and exceptions set
forth herein, we are of the opinion that (i) the Shares have been lawfully and
duly authorized; and (ii) such Shares have been validly issued and are fully
paid and nonassessable.

        We are members of the bar of the State of Maryland and the District of
Columbia and do not hold ourselves out as being experts in the law of any other
state.  This opinion is limited to the laws of the United States and the
General Corporation Law of Delaware.  Although we do not hold ourselves out as
being experts in the laws of Delaware, we have made an investigation of such
laws to the extent necessary to render our opinion.  Our opinion is rendered
only with respect to the laws and the rules, regulations and orders thereunder
that are currently in effect.
